Experiment Einstein Quotes

The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science.

A human being is a part of the whole called by us universe, a part limited in time and space. He experiences himself, his thoughts and feeling as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.

The only source of knowledge is experience.

Learning is experience. Everything else is just information.

No amount of experimentation can ever prove me right; a single experiment can prove me wrong.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom the emotion is a stranger, who can no longer pause to wonder and stand wrapped in awe, is as good as dead —his eyes are closed. The insight into the mystery of life, coupled though it be with fear, has also given rise to religion. To know what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull faculties can comprehend only in their most primitive forms—this knowledge, this feeling is at the center of true religiousness.

We experience ourselves our thoughts and feelings as something separate from the rest. A kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us.

Truth is what stands the test of experience.

The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, is as good as dead, and his eyes are dimmed (Albert Einstein)

Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next - and disappear. That's why it's so important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives.

The religion of the future will be a cosmic religion. It should transcend a personal God and avoid dogmas and theology. Covering both the natural and the spiritual, it should be based on a religious sense arising from the experience of all things, natural and spiritual, as a meaningful unity. Buddhism answers this description.

Children don’t heed the life experiences of their parents, and nations ignore history. Bad lessons always have to be learned anew.

A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it.

The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and science. He who knows it not and can no longer wonder, no longer feel amazement, is as good as dead, a snuffed-out candle.

I assert that the cosmic religious experience is the strongest and the noblest driving force behind scientific research.

Ethical axioms are found and tested not very differently from the axioms of science. Truth is what stands the test of experience.

The supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a simple datum of experience.

A new idea comes suddenly and in a rather intuitive way,” Einstein once said, “but intuition is nothing but the outcome of earlier intellectual experience.

In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds.

One of the strongest motives that leads men to art and science is escape from everyday life with its painful crudity and hopeless dreariness. Such men make this cosmos and its construction the pivot of their emotional life, in order to find the peace and security which they cannot find in the narrow whirlpool of personal experience.

A new idea comes suddenly and in a rather intuitive way, but intuition is nothing but the outcome of earlier intellectual experience.

The most beautiful experience we can have is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead and his eyes are dimmed.

It is very difficult to explain this feeling to anyone who is entirely without it, especially as there is no anthropomorphic conception of God corresponding to it. The individual feels the nothingness of human desires and aims and the sublimity and marvelous order which reveal themselves both in Nature and in the world of though. He looks upon individual existence as a sort of prison and wants to experience the universe as a single significant whole.

Did you know: The only source of knowledge is experience

When Einstein died, his greatest rival, Bohr, found for him words of moving admiration. When a few years later Bohr in turn died, someone took a photograph of the blackboard in his study. There’s a drawing on it. A drawing of the ‘light-filled box’ in Einstein’s thought experiment. To the very last, the desire to challenge oneself and understand more. And to the very last: doubt

To the extent that experience is the sum of our memories and wisdom the sum of experience, having a better memory would mean knowing not only more about the world, but also more about myself.

The point of what Einstein had done did not lie in this or that experiment. It lay, as Alan saw, in the ability to doubt, to take ideas seriously, and to follow them to a logical if upsetting conclusion.

You make experiments and I make theories. Do you know the difference? A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it. {Remark to scientist Herman Francis Mark}

The most beautiful thing we can experience is the mysterious.

The most beautiful and deepest experience a man can have is the sense of the mysterious. It is the underlying principle of religion as well as all serious endeavor in art and science. He who never had this experience seems to me, if not dead, then at least blind. To sense that behind anything that can be experienced there is a something that our mind cannot grasp and whose beauty and sublimity reaches us only indirectly and as a feeble reflection, this is religiousness. In this sense I am religious. To me it suffices to wonder at these secrets and to attempt humbly to grasp with my mind a mere image of the lofty structure of all that there is.

In my experience, the best creative work is never done when one is unhappy.

The definition of insanity is doing the same experiment and expecting different results.

Common to all these types is the anthropomorphic character of their conception of God. In general, only individuals of exceptional endowments, and exceptionally high-minded communities, rise to any considerable extent above this level. But there is a third stage of religious experience which belongs to all of them, even though it is rarely found in a pure form: I shall call it cosmic religious feeling. It is very difficult to elucidate this feeling to anyone who is entirely without it, especially as there is no anthropomorphic conception of God corresponding to it.

The most beautiful emotion we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of all true art and science. He to whom

How can it be that mathematics, being after all a product of human thought independent of experience, is so admirably appropriate to the objects of reality?

Concepts that have proven useful in ordering things easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens. Thus they come to be stamped as “necessities of thought”, “a priori givens”, etc. The path of scientific advance is often made impassable for a long time through such errors. For that reason, it is by no means an idle game if we become practiced in analyzing the long commonplace concepts and exhibiting those circumstances upon which their justification and usefulness depend, how they have grown up, individually, out of the givens of experience. By this means, their all-too-great authority will be broken. They will be removed if they cannot be properly legitimated, corrected if their correlation with given things be far too superfluous, replaced by others if a new system can be established that we prefer for whatever reason.

The most beautiful thing we can experience is the mysterious….He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead. —ALBERT EINSTEIN

what we call expertise is really just “vast amounts of knowledge, pattern-based retrieval, and planning mechanisms acquired over many years of experience in the associated domain.” In other words, a great memory isn’t just a by-product of expertise; it is the essence of expertise.

…it seemed to Kirsch that the most reliable guide to the mental landscape of a patient was the patient himself. He was better placed to explain his behaviour and his experiences than anyone else. Yet wherever Kirsch went, the patient was the very last person anyone thought to consult. Because, of course, the patient was insane.

there is found a third level of religious experience, even if it is seldom found in a pure form. I will call it the cosmic religious sense. This is hard to make clear to those who do not experience it, since it does not involve an anthropomorphic idea of God; the individual feels the vanity of human desires and aims, and the nobility and marvelous order which are revealed in nature and in the world of thought. He feels the individual destiny as an imprisonment and seeks to experience the totality of existence as a unity full of significance. Indications of this cosmic religious sense can be found even on earlier levels of development—for example, in the Psalms of David and in the Prophets. The cosmic element is much stronger in Buddhism, as, in particular, Schopenhauer's magnificent essays have shown us. The religious geniuses of all times have been distinguished by this cosmic religious sense, which recognizes neither dogmas nor God made in man's image. Consequently there cannot be a church whose chief doctrines are based on the cosmic religious experience. It comes about, therefore, that we find precisely among the heretics of all ages men who were inspired by this highest religious experience; often they appeared to their contemporaries as atheists, but sometimes also as saints.

The mystical trend of our time, which shows itself particularly in the rampant growth of the so-called Theosophy and Spiritualism, is for me no more than a symptom of weakness and confusion. Since our inner experiences consist of reproductions, and combinations of sensory impressions, the concept of a soul without a body seem to me to be empty and devoid of meaning. - Albert Einstein, letter of February 5, 1921

The most beautiful emotion we can experience is the mystical. It is the source of all true art and science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead.

A human being is a part of the whole called by us “the universe,” a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest—a kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening the circle of understanding and compassion to embrace all living creatures and the whole of nature in its beauty. —ALBERT EINSTEIN

The most beautiful and profound emotion we can experience is the sensation of the mystical. It is at the root of all true science. That deeply emotional conviction of the presence of a superior reasoning power which is revealed in the incomprehensible Universe is my idea of God.

I once expected to spend seven years walking around the world on foot. I walked from Mexico to Panama where the road ended before an almost uninhabited swamp called the Choco Colombiano. Even today there is no road. Perhaps it is time for me to resume my wanderings where I left off as a tropical tramp in the slums of Panama. Perhaps like Ambrose Bierce who disappeared in the desert of Sonora I may also disappear. But after being in all mankind it is hard to come to terms with oblivion - not to see hundreds of millions of Chinese with college diplomas come aboard the locomotive of history - not to know if someone has solved the riddle of the universe that baffled Einstein in his futile efforts to make space, time, gravitation and electromagnetism fall into place in a unified field theory - never to experience democracy replacing plutocracy in the military-industrial complex that rules America - never to witness the day foreseen by Tennyson 'when the war-drums no longer and the battle-flags are furled, in the parliament of man, the federation of the world.' I may disappear leaving behind me no worldly possessions - just a few old socks and love letters, and my windows overlooking Notre-Dame for all of you to enjoy, and my little rag and bone shop of the heart whose motto is 'Be not inhospitable to strangers lest they be angels in disguise.' I may disappear leaving no forwarding address, but for all you know I may still be walking among you on my vagabond journey around the world." [Shakespeare & Company, archived statement]

William James wrote (in Principles of Psychology in 1890): "In youth we may have an absolutely new experience, subjective or objective, every hour of the day. Apprehension is vivid, retentiveness strong, and our recollections of that time, like those of a time spent in rapid and interesting travel, are of something intricate, multitudinous and long-drawn-out. But as each passing year converts some of this experience into automatic routine which we hardly note at all, the days and the weeks smooth themselves out in recollection to contentless units..." Life seems to speed up as we get older because life gets less memorable as we get older.

Through the reading of popular scientific books I soon reached the conviction that much in the stories of the Bible could not be true. The consequence was a positively fanatic orgy of freethinking coupled with the impression that youth is intentionally being deceived by the state through lies; it was a crushing impression. Mistrust of every kind of authority grew out of this experience, a skeptical attitude toward the convictions that were alive in any specific social environment - an attitude that has never again left me. - Albert Einstein, Autobiographical Notes, edited by Paul Arthur Schilpp

The importance of C.F. Gauss for the development of modern physical theory and especially for the mathematical fundament of the theory of relativity is overwhelming indeed; also his achievement of the system of absolute measurement in the field of electromagnetism. In my opinion it is impossible to achieve a coherent objective picture of the world on the basis of concepts which are taken more or less from inner psychological experience.

Development of Western science is based on two great achievements: the invention of the formal logical system (in Euclidean geometry) by the Greek philosophers, and the discovery of the possibility to find out causal relationships by systematic experiment (during the Renaissance). In my opinion, one has not to be astonished that the Chinese sages have not made these steps. The astonishing thing is that these discoveries were made at all.

The most beautiful experience we can have is the mysterious.

The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science.

Information is not knowledge. The only source of knowledge is experience.

Einstein once wrote, “The most beautiful experience we can have is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science.

Albert Einstein, for one, repeatedly expressed these feelings, as in the following celebrated passage (Einstein, 1949, p. 5): The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science…the mystery of the eternity of life, and the inkling of the marvellous structure of reality, together with the single-hearted endeavor to comprehend a portion, be it ever so tiny, of the reason that manifests itself in nature.

Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things. In my opinion the answer to this question is, briefly, this:--As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.

Despite the earnest belief of most of his fans, Einstein did not win his Nobel Prize for the theory of relativity, special or general. He won for explaining a strange effect in quantum mechanics, the photoelectric effect. His solution provided the first real evidence that quantum mechanics wasn’t a crude stopgap for justifying anomalous experiments, but actually corresponds to reality. And the fact that Einstein came up with it is ironic for two reasons. One, as he got older and crustier, Einstein came to distrust quantum mechanics. Its statistical and deeply probabilistic nature sounded too much like gambling to him, and it prompted him to object that “God does not play dice with the universe.” He was wrong, and it’s too bad that most people have never heard the rejoinder by Niels Bohr: “Einstein! Stop telling God what to do.

In the temple of science are many mansions, and various indeed are they that dwell therein and the motives that have led them thither. Many take to science out of a joyful sense of superior intellectual power; science is their own special sport to which they look for vivid experience and the satisfaction of ambition; many others are to be found in the temple who have offered the products of their brains on this altar for purely utilitarian purposes. Were [someone to] drive all the people belonging to these two categories out of the temple, the assemblage would be seriously depleted, but there would still be some men, of both present and past times, left inside. Our Planck is one of them, and that is why we love him.

A human being is part of the whole, called by us “Universe,” a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest—a kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us.

Albert Einstein once said, "My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities". And "I love Humanity but I hate humans." The abstract concepts of social justice and humanity came easily, but the concrete experience of encountering another person was too hard.

Instead of studying old traditions, emphasis is now placed on new observations and experiments. When present observation collides with past tradition, we give precedence to the observation. Of course, physicists analysing the spectra of distant galaxies, archaeologists analysing the finds from a Bronze Age city, and political scientists studying the emergence of capitalism do not disregard tradition. They start by studying what the wise people of the past have said and written. But from their first year in college, aspiring physicists, archaeologists and political scientists are taught that it is their mission to go beyond what Einstein, Heinrich Schliemann and Max Weber ever knew.

Somebody who reads only newspapers and at best books of contemporary authors looks to me like an extremely near-sighted person who scorns eyeglasses. He is completely dependent on the prejudices and fashions of his times, since he never gets to see or hear anything else. And what a person thinks on his own without being stimulated by the thoughts and experiences of other people is even in the best case rather paltry and monotonous.

The most beautiful emotion we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of all true art and science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead, a snuffed-out candle. To sense that behind anything that can be experienced there is something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense, and in this sense only, I am a devoutly religious man.5 People

The chess experiments reveal a telling fact about memory, and about expertise in general: We don’t remember isolated facts; we remember things in context.

What a person does on his own, without being stimulated by the thoughts and experiences of others, is even in the best of cases rather paltry and monotonous.

It is a wonderful feeling to recognize the unifying features of a complex of phenomena which present themselves as quite unconnected to the direct experience of the senses.

A body will accelerate in proportion to the force acting upon it,

In a Sense, we all are Time Travelers! We are Surviving each and every Active Time-Point in this Timeline.......

Since Einstein derived his famous equation, literally millions of experiments have confirmed his revolutionary ideas.

I was always telling myself, “Keep it simple.” But as Albert Einstein pointed out, “Everything should be made as simple as possible, but not simpler.

Imagination is more important than knowledge.

All true learning is experience. Everything else is just information.

The only source of knowledge is the experience

The most beautiful experience we can have is the mysterious. It is the fundamental emotion which stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed. —ALBERT EINSTEIN

Each such cycle is a unique event; diet, choice, selection, season, weather, digestion, decomposition and regeneration differ each time it happens. Thus, it is the number of such cycles, great and small, that decide the potential for diversity. We should feel ourselves privileged to be part of such eternal renewal. Just by living we have achieved immortality - as grass, grasshoppers, gulls, geese and other people. We are of the diversity we experience in every real sense. If, as physical scientists assure us, we all contain a few molecules of Einstein, and if the atomic particles of our physical body reach to the outermost bounds of the universe, then we are all de facto components of all things. There is nowhere left for us to go if we are already everywhere, and this is, in truth, all we will ever have or need. If we love ourselves at all, we should respect all things equally, and not claim any superiority over what are, in effect, our other parts. Is the hand superior to the eye? The bishop to the goose? The son to the mother?

Certain it is that a conviction, akin to religious feeling, of the rationality or intelligibility of the world lies behind all scientific work of a higher order.... This firm belief, a belief bound up with deep feeling, in a superior mind that reveals itself in the world of experience, represents my conception of God.

The most beatiful and most profound experience is the sensation of the mystical. It is the sower of all true science. He to whom this emotion is a stranger, who can no longer stand rapt in awe, is as good as dead.

Few of us make any serious effort to remember what we read. When I read a book, what do I hope will stay with me a year later? If it’s a work of nonfiction, the thesis, maybe, if the book has one. A few savory details, perhaps. If it’s fiction, the broadest outline of the plot, something about the main characters (at least their names), and an overall critical judgment about the book. Even these are likely to fade. Looking up at my shelves, at the books that have drained so many of my waking hours, is always a dispiriting experience. One Hundred Years of Solitude: I remember magical realism and that I enjoyed it. But that’s about it. I don’t even recall when I read it. About Wuthering Heights I remember exactly two things: that I read it in a high school English class and that there was a character named Heathcliff. I couldn’t say whether I liked the book or not.

Watson,” says Frank, “experiment time. Could you go into the kitchen and get one balloon, two packets of salt, three packets of pepper, and one plastic spoon?” “That sounds about as scientific as . . . my peashooter,” says Watson, heading for the kitchen as Frank and the robots finish cleaning up the lab. Watson returns with the experiment supplies. “I can’t wait to see what you make with this.” Frank rips open the salt and pepper packets and dumps everything into one pile on the table. He blows up the balloon. “Rub this on your head, Watson.” Watson rubs the balloon on his head. “Oh, this is much more scientific.” “Just watch,” says Frank. “Now put the balloon over the salt and pepper.” Watson moves the balloon. The positively charged, lighter pieces of pepper separate from the heavier pieces of salt and stick to the balloon. “Wireless,” says Frank. “And cheap. Now watch this.” Frank rubs the plastic spoon on Watson’s sweater. He turns the water on in the lab sink so that a small, steady stream flows out. “Observe.” Frank puts the spoon near the water column. “No way!” says Watson. “The water is bending toward the spoon!” Klink beeps, “In both cases, extra negative charge caused by gathering electrons . . . attracts positively charged pepper pieces and water stream.

The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed.

Until now, I've been writing about "now" as if it were literally an instant of time, but of course human faculties are not infinitely precise. It is simplistic to suppose that physical events and mental events march along exactly in step, with the stream of "actual moments" in the outside world and the stream of conscious awareness of them perfectly synchronized. The cinema industry depends on the phenomenon that what seems to us a movie is really a succession of still pictures, running at twenty-five [sic] frames per second. We don't notice the joins. Evidently the "now" of our conscious awareness stretches over at least 1/25 of a second. In fact, psychologists are convinced it can last a lot longer than that. Take he familiar "tick-tock" of the clock. Well, the clock doesn't go "tick-tock" at all; it goes "tick-tick," every tick producing the same sound. It's just that our consciousness runs two successive ticks into a singe "tick-tock" experience—but only if the duration between ticks is less than about three seconds. A really bug pendulum clock just goes "tock . . . tock . . . tock," whereas a bedside clock chatters away: "ticktockticktock..." Two to three seconds seems to be the duration over which our minds integrate sense data into a unitary experience, a fact reflected in the structure of human music and poetry.

Only a few centuries ago, a mere second in cosmic time, we knew nothing of where or when we were. Oblivious to the rest of the cosmos, we inhabited a kind of prison, a tiny universe bounded by a nutshell. How did we escape from the prison? It was the work of generations of searchers who took five simple rules to heart: 1. Question authority. No idea is true just because someone says so, including me. 2. Think for yourself. Question yourself. Don't believe anything just because you want to. Believing something doesn't make it so. 3. Test ideas by the evidence gained from observation and experiment. If a favorite idea fails a well-designed test, it's wrong. Get over it. 4. Follow the evidence wherever it leads. If you have no evidence, reserve judgment. And perhaps the most important rule of all... 5. Remember: you could be wrong. Even the best scientists have been wrong about some things. Newton, Einstein, and every other great scientist in history -- they all made mistakes. Of course they did. They were human. Science is a way to keep from fooling ourselves, and each other.

Time is just an illusion. Einstein told us that. If this is the first time you have heard it, you may find it a hard concept to get your head around, because you see everything happening—one thing after the other. What quantum physicists and Einstein tell us is that everything is happening simultaneously. If you can understand that there is no time, and accept that concept, then you will see that whatever you want in the future already exists. If everything is happening at the one time, then the parallel version of you with what you want already exists! It takes no time for the Universe to manifest what you want. Any time delay you experience is due to your delay in getting to the place of believing, knowing, and feeling that you already have it. It is you getting yourself on the frequency of what you want. When you are on that frequency, then what you want will appear.

It is a special blessing to belong among those who can and may devote their best energies to the contemplation and exploration of objective and timeless things. How happy and grateful I am for having been granted this blessing, which bestows upon one a large measure of independence from one's personal fate and from the attitude of one's contemporaries. Yet this independence must not inure us to the awareness of the duties that constantly bind us to the past, present and future of humankind at large. Our situation on this earth seems strange. Every one of us appears here, involuntarily and uninvited, for a short stay, without knowing the why and the wherefore. In our daily lives we feel only that man is here for the sake of others, for those whom we love and for many other beings whose fate is connected with our own. I am often troubled by the thought that my life is based to such a large extent on the work of my fellow human beings, and I am aware of my great indebtedness to them. I do not believe in free will. Schopenhauer's words: 'Man can do what he wants, but he cannot will what he wills,' accompany me in all situations throughout my life and reconcile me with the actions of others, even if they are rather painful to me. This awareness of the lack of free will keeps me from taking myself and my fellow men too seriously as acting and deciding individuals, and from losing my temper. I have never coveted affluence and luxury and even despise them a good deal. My passion for social justice has often brought me into conflict with people, as has my aversion to any obligation and dependence I did not regard as absolutely necessary. [Part 2] I have a high regard for the individual and an insuperable distaste for violence and fanaticism. All these motives have made me a passionate pacifist and antimilitarist. I am against any chauvinism, even in the guise of mere patriotism. Privileges based on position and property have always seemed to me unjust and pernicious, as does any exaggerated personality cult. I am an adherent of the ideal of democracy, although I know well the weaknesses of the democratic form of government. Social equality and economic protection of the individual have always seemed to me the important communal aims of the state. Although I am a typical loner in daily life, my consciousness of belonging to the invisible community of those who strive for truth, beauty, and justice keeps me from feeling isolated. The most beautiful and deepest experience a man can have is the sense of the mysterious. It is the underlying principle of religion as well as of all serious endeavour in art and science. He who never had this experience seems to me, if not dead, then at least blind. To sense that behind anything that can be experienced there is a something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense I am religious. To me it suffices to wonder at these secrets and to attempt humbly to grasp with my mind a mere image of the lofty structure of all there is.

And all I’m saying is that it is within our capability to survive. I don’t guarantee it. Prophecy is a lost art. And I don’t know what the probabilities are that we will go one way or another. And no one says it’s easy. But it is clear, as Einstein said, that if we do not make a change in our way of thinking, all is lost.

A human being is a part of the whole, called by us ‘Universe,’ a part limited in time and space. He experiences himself, his thoughts and feelings as something separate from the rest—a kind of optical delusion of his consciousness. The striving to free oneself from this delusion is the one issue of true religion.” ~ Albert Einstein

Einstein once said, “but intuition is nothing but the outcome of earlier intellectual experience.

To the extent that experience is the sum of our memories and wisdom the sum of experience,

Physicists had only recently discovered radioactivity,

light was both a wave and a particle.

Einstein wrote, “Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.

Other mathematical geniuses, Einstein and Bertrand Russell among them, recount similarly revelatory experiences in early adolescence.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science." – Albert Einstein

If we are to help save the human race, we must first recognize the humanity in all, no matter their station in life.

Even the smallest among us have the potential to add a gigantic amount of energy to this world. And if you don’t believe that, first thing tomorrow morning, just look in the mirror.

Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next—and disappear. That’s why it’s important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives.

A human being,” Einstein concluded, “is a part of the whole, called by us ‘Universe,’ a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest—a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.”6

All truths in science must be demonstrated either through experiment or through mathematical proof. The idea that something must be so because Newton or Einstein said so is simply not scientific.

A human being is a spatially and temporally limited piece of the whole of what we call the "universe". He experiences himself and his feelings as separated from the rest, an optical illusion of his consciousness. The quest for liberation from this bondage [or delusion] is the sole object of real religion. Not nurturing the delusion but only overcoming it gives us the attainable measure of inner peace.

My experience had validated the old saw that practice makes perfect. But only if it’s the right kind of concentrated, self-conscious, deliberate practice. I’d learned firsthand that with focus, motivation, and, above all, time, the mind can be trained to do extraordinary things. This was a tremendously empowering discovery. It made me ask myself: What else was I capable of doing, if only I used the right approach?

The law of conservation of energy, reborn as the law of conservation of mass/energy, has established itself as one of the few unshakable theoretical guideposts in the wilderness of the world of our sense experiences. In scope and generality it surpasses Newton's laws of motion, Maxwell's equations for electricity and magnetism, and even Einstein's potent little E=mc². It comes as close to an absolute truth as our uncertain age will permit.

Time is relative. In human life, time is experience. The faster you archive a significant experience to your memory, the more you live in the same clock time. In physics, experience is represented by the distance traveled, and this entire thing is called the Relativity of Time. I want to age and die through archiving my experiences, not watching my biological clock. Please don't waste my clock time with mediocrity and egotism, let me use it towards serving to others.

there’s a telling answer to the question of what Albert Einstein claimed was so remarkable it could be labeled as both “the most beautiful thing we can experience” and “the source of all true science and art.” His contention: the mysterious.

He might also interpret his experience thus: “My body of reference (the carriage) remains permanently at rest. With reference to it, however, there exists (during the period of application of the brakes) a gravitational field which is directed forwards and which is variable with respect to time. Under the influence of this field, the embankment together with the earth move non-uniformly in such a manner that their original velocity in the backward direction is continuously reduced.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom the emotion is a stranger, who can no longer pause to wonder and stand wrapped in awe, is as good as dead—his eyes are closed. —Albert Einstein

Einstein never accepted that the universe was governed by chance; his feelings were summed up in his famous statement, ‘God does not play dice.’ Most other scientists, however, were willing to accept quantum mechanics because it agreed perfectly with experiment.

David Park is a physicist and philosopher at Williams College in Massachusetts with a lifelong interest in a time which he too thinks doesn't pass. For Park, the passage of time is not so much an illusion as a myth, "because it involves no deception of the senses.... One cannot perform any experiment to tell unambiguously whether time passes or not." This is certainly a telling argument. After all, what reality can be attached to a phenomenon that can never be demonstrated experimentally? In fact, it is not even clear how to think about demonstrating the flow of time experimentally. As the apparatus, laboratory, experimenter, technicians, humanity generally and the universe as a whole are apparently caught up in the same inescapable flow, how can any bit of the universe be "stopped in time" in order to register the flow going on in the rest of it? It is analogous to claiming that the whole universe is moving through space at the same speed—or, to make the analogy closer, that space is moving through space. How can such a claim ever be tested?

Perhaps there are many "nows" of varying duration, depending on just what it is we are doing. We must face up to the fact that, at least in the case of humans, the subject experiencing subjective time is not a perfect, structureless observer, but a complex, multilayered, multifaceted psyche. Different levels of our consciousness may experience time in quite different ways. This is evidently the case in terms of response time. You have probably had the slightly unnerving experience of jumping at the sound of a telephone a moment or two before you actually hear it ring. The shrill noise induces a reflex response through the nervous system much faster than the time it takes to create the conscious experience of the sound. It is fashionable to attribute certain qualities, such as speech ability, to the left side of the brain, whereas others, such as musical appreciation, belong to processes occurring on the right side. But why should both hemispheres experience a common time? And why should the subconscious use the same mental clock as the conscious?

It cannot be overstated that the emphasis on visual thinking among German-speaking scientists and engineers circa 1900 was widespread. Yet in 1905 it was Einstein who combined visual thinking with Gedanken experiments and quasiaesthetic notions with dazzling results.

Albert Einstein wrote, ‘A human being is a part of the whole, called by us “Universe”, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest, a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.’ Apparently,

Warping begets warping in a nonlinear, self-bootstrapping manner. This is a fundamental feature of Einstein’s relativistic laws, and so different from everyday experience. It’s somewhat like a hypothetical science-fiction character who goes backward in time and gives birth to herself.

Albert Einstein hardly ever set foot in the laboratory; he didn’t test phenomena or use elaborate equipment. He was a theorist who perfected the “thought experiment,” in which you engage nature through your imagination, by inventing a situation or model and then working out the consequences of some physical principle. In Germany before World War II, laboratory-based physics far outranked theoretical physics in the minds of most Aryan scientists. Jewish physicists were all relegated to the lowly theorists’ sandbox and left to fend for themselves. And what a sandbox that would become.

the end of his life, he was asked what stuck in his mind about his experiences in South America and on the Beagle. And he remembered climbing to the peak of the Andes in Peru or Chile—I can’t remember—and then turning as he reached the peak and looking behind him. And he said, it was like the Hallelujah Chorus in the Messiah, playing with full orchestra, blaring in his head, because he was on top of the world. He was looking down almost like God upon this creation, which he had begun to sort out in his own mind as he’d been climbing, as it were. At the end of his life he was asked, “What’s the most extraordinary experience you had?” And he remembered climbing to the peak of the Andes. And then he slept on it, and the next day he came back to the person and he said, “No, it was the rain forest. It was sitting there and feeling that there must be more to man than the breath in his body.

According to Ericsson, what we call expertise is really just “vast amounts of knowledge, pattern-based retrieval, and planning mechanisms acquired over many years of experience in the associated domain.” In other words, a great memory isn’t just a by-product of expertise; it is the essence of expertise.

Find a society that's adopted the teachings of Spinoza, Voltaire, Galileo, Einstein, Thomas Paine, Thomas Jefferson and gone down the pits—as a result of doing that—into famine and war and dictatorship and torture and repression. That's the experiment I would like to run. I don't think that's going to end up with a gulag.

When the combined taste, smell, and textural stimuli reach the brain, they remain to be interpreted. Whether the overall sensation will be pleasant, repulsive, or somewhere in between will depend on individual physiological differences, on previous experience (“just like my mother used to make”), and on cultural habituation (haggis, anyone?).

You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next—and disappear. That’s why it’s important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible

I watched as she took a second sip, imagining alcohol crossing the placental wall, damaging brain cells, reducing our unborn child from a future Einstein to a physicist who would fall just short of taking science to a new level. A child who would never have the experience described by Richard Feynman of knowing something about the universe that no one had before

Psychologists have devised some ingenious ways to help unpack the human "now." Consider how we run those jerky movie frames together into a smooth and continuous stream. This is known as the "phi phenomenon." The essence of phi shows up in experiments in a darkened room where two small spots are briefly lit in quick succession, at slightly separated locations. What the subjects report seeing is not a succession of spots, but a single spot moving continuously back and forth. Typically, the spots are illuminated for 150 milliseconds separated by an interval of fifty milliseconds. Evidently the brain somehow "fills in" the fifty-millisecond gap. Presumably this "hallucination" or embellishment occurs after the event, because until the second light flashes the subject cannot know the light is "supposed" to move. This hints that the human now is not simultaneous with the visual stimulus, but a bit delayed, allowing time for the brain to reconstruct a plausible fiction of what has happened a few milliseconds before. In a fascinating refinement of the experiment, the first spot is colored red, the second green. This clearly presents the brain with a problem. How will it join together the two discontinuous experiences—red spot, green spot—smoothly? By blending the colors seamlessly into one another? Or something else? In fact, subjects report seeing the spot change color abruptly in the middle of the imagined trajectory, and are even able to indicate exactly where using a pointer. This result leaves us wondering how the subject can apparently experience the "correct" color sensation before the green spot lights up. Is it a type of precognition? Commenting on this eerie phenomenon, the philosopher Nelson Goodman wrote suggestively: "The intervening motion is produced retrospectively, built only after the second flash occurs and projected backwards in time." In his book Consciousness Explained , philosopher Daniel Dennett points out that the illusion of color switch cannot actually be created by the brain until after the green spot appears. "But if the second spot is already 'in conscious experience,' wouldn't it be too late to interpose the illusory content between the conscious experience of the red spot and the conscious experience of the green spot?

Without time, there would be no need for a memory. But without a memory, would there be such a thing as time? I don’t mean time in the sense that, say, physicists speak of it: the fourth dimension, the independent variable, the quantity that dilates when you approach the speed of light. I mean psychological time, the tempo at which we experience life’s passage. Time as a mental construct.

Einstein's prohibition against travelling faster than light may clash with our common sense, but, on this question, why should we trust common sense? Why should our experience at 10 kilometers-an-hour constrain the laws of nature at 300,000 kilomters per second? Relativity does set limits on what humans can ultimately do, but the universe is not required to be in perfect harmony with human ambition.

A human being is a spatially and temporally limited piece of the whole of what we call the "universe". He experiences himself and his feelings as separated from the rest, an optical illusion of his consciousness. The quest for liberation from this bondage [or delusion] is the sole object of real religion. Not nurturing the illusion but only overcoming it gives us the attainable measure of inner peace.

Every clear night is an opportunity to experience something amazing. I have seen comets stretch across the sky, viewed sunlight glinting off the dust that floats between the planets, and witnessed a Milky Way so bright that the glow of its billion stars cast a shadow at my feet. But in all my life I have never seen anything as awe inspiring, as awesome—in the original definition of the word—as a total eclipse of the Sun.

Gruber speaks of an "evolving systems" approach to the study of creativity: that is, one monitors simultaneously the organization of knowledge in a domain, the purpose(s) pursued by the creator, and the affective experiences he or she undergoes. While these systems are only "loosely coupled," their interaction over time helps one understand the ebb and flow of creative activity over the course of a productive human life.

My four things I care about are truth, meaning, fitness and grace. [...] Sam [Harris] would like to make an argument that the better and more rational our thinking is, the more it can do everything that religion once did. [...] I think about my personal physics hero, Dirac – who was the guy who came up with the equation for the electron, less well-known than the Einstein equations but arguably even more beautiful...in order to predict that, he needed a positively-charged and a negatively-charged particle, and the only two known at the time were the electron and the proton to make up, let's say, a hydrogen atom. Well, the proton is quite a bit heavier than the electron and so he told the story that wasn't really true, where the proton was the anti-particle of the electron, and Heisenberg pointed out that that couldn't be because the masses are too far off and they have to be equal. Well, a short time later, the anti-electron -- the positron, that is -- was found, I guess by Anderson at Caltech in the early 30s and then an anti-proton was created some time later. So it turned out that the story had more meaning than the exact version of the story...so the story was sort of more true than the version of the story that was originally told. And I could tell you a similar story with Einstein, I could tell it to you with Darwin, who, you know, didn't fully understand the implications of his theory, as is evidenced by his screwing up a particular kind of orchid in his later work...not understanding that his theory completely explained that orchid! So there's all sorts of ways in which we get the...the truth wrong the first several times we try it, but the meaning of the story that we tell somehow remains intact. And I think that that's a very difficult lesson for people who just want to say, 'Look, I want to'...you know, Feynman would say, "If an experiment disagrees with you, then you're wrong' and it's a very appealing story to tell to people – but it's also worth noting that Feynman never got a physical law of nature and it may be that he was too wedded to this kind of rude judgment of the unforgiving. Imagine you were innovating in Brazilian jiu-jitsu. The first few times might not actually work. But if you told yourself the story, 'No, no, no – this is actually genius and it's working; no, you just lost three consecutive bouts' -- well, that may give you the ability to eventually perfect the move, perfect the technique, even though you were lying to yourself during the period in which it was being set up. It's a little bit like the difference between scaffolding and a building. And too often, people who are crazy about truth reject scaffolding, which is an intermediate stage in getting to the final truth.

He argued that expertise in “the field of shoemaking, painting, building, [or] confectionary” is the result of the same accumulation of “experiential linkings.” According to Ericsson, what we call expertise is really just “vast amounts of knowledge, pattern-based retrieval, and planning mechanisms acquired over many years of experience in the associated domain.” In other words, a great memory isn’t just a by-product of expertise; it is the essence of expertise

Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next—and disappear. That’s why it’s important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives. William James first wrote about the curious warping and foreshortening of psychological time in his Principles of Psychology in 1890: “In youth we may have an absolutely new experience, subjective or objective, every hour of the day. Apprehension is vivid, retentiveness strong, and our recollections of that time, like those of a time spent in rapid and interesting travel, are of something intricate, multitudinous and long-drawn-out,” he wrote. “But as each passing year converts some of this experience into automatic routine which we hardly note at all, the days and the weeks smooth themselves out in recollection to contentless units, and the years grow hollow and collapse.” Life seems to speed up as we get older because life gets less memorable as we get older. “If to remember is to be human, then remembering more means being more human,” said Ed.

It is said that a student of sexing must work through at least 250,000 chicks before attaining any degree of proficiency. Even if the sexer calls it “intuition,” it’s been shaped by years of experience. It is the vast memory bank of chick bottoms that allows him or her to recognize patterns in the vents glanced at so quickly. In most cases, the skill is not the result of conscious reasoning, but pattern recognition. It is a feat of perception and memory, not analysis.

The most beautiful and most profound emotion we can experience is the sensation of the mystical. It is the sower of all true science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead. To know that what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty which our dull faculties can comprehend only in their most primitive forms—this knowledge, this feeling is at the center of true religiousness.” And

At some very low level, we all share certain fictions about time, and they testify to the continuity of what is called human nature, however conscious some, as against others, may become of the fictive quality of these fictions. It seems to follow that we shall learn more concerning the sense-making paradigms, relative to time, from experimental psychologists than from scientists or philosophers, and more from St. Augustine than from Kant or Einstein because St. Augustine studies time as the soul's necessary self-extension before and after the critical moment upon which he reflects. We shall learn more from Piaget, from studies of such disorders as déjà vu, eidetic imagery, the Korsakoff syndrome, than from the learned investigators of time's arrow, or, on the other hand, from the mythic archetypes. Let us take a very simple example, the ticking of a clock. We ask what it says: and we agree that it says tick-tock. By this fiction we humanize it, make it talk our language. Of course, it is we who provide the fictional difference between the two sounds; tick is our word for a physical beginning, tock our word for an end. We say they differ. What enables them to be different is a special kind of middle. We can perceive a duration only when it is organized. It can be shown by experiment that subjects who listen to rhythmic structures such as tick-tock, repeated identically, 'can reproduce the intervals within the structure accurately, but they cannot grasp spontaneously the interval between the rhythmic groups,' that is, between tock and tick, even when this remains constant. The first interval is organized and limited, the second not. According to Paul Fraisse the tock-tick gap is analogous to the role of the 'ground' in spatial perception; each is characterized by a lack of form, against which the illusory organizations of shape and rhythm are perceived in the spatial or temporal object. The fact that we call the second of the two related sounds tock is evidence that we use fictions to enable the end to confer organization and form on the temporal structure. The interval between the two sounds, between tick and tock is now charged with significant duration. The clock's tick-tock I take to be a model of what we call a plot, an organization that humanizes time by giving it form; and the interval between tock and tick represents purely successive, disorganized time of the sort that we need to humanize. Later I shall be asking whether, when tick-tock seems altogether too easily fictional, we do not produce plots containing a good deal of tock-tick; such a plot is that of Ulysses.

The most beautiful emotion we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of all true art and science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead, a snuffed-out candle. To sense that behind anything that can be experienced there is something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense, and in this sense only, I am a devoutly religious man.

Take a moment, right now, and consider the enormity of activity going on inside of you – from the billions of cells to the even more billions of microscopic organisms. And in that same moment consider the enormity of activity in the oceans, the forests, the jungles, the earth below your feet, right now. And before you take your next breath, consider what might be going on in the outer regions of the universe. Finally, ask yourself, am I really in a position to discount possibilities beyond the limits of my conscious experience?

A human being,’ said Einstein, ‘is part of the whole, which we call the Universe; a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest – a kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.

The generalized theory of relativity has furnished still more remarkable results. This considers not only uniform but also accelerated motion. In particular, it is based on the impossibility of distinguishing an acceleration from the gravitation or other force which produces it. Three consequences of the theory may be mentioned of which two have been confirmed while the third is still on trial: (1) It gives a correct explanation of the residual motion of forty-three seconds of arc per century of the perihelion of Mercury. (2) It predicts the deviation which a ray of light from a star should experience on passing near a large gravitating body, the sun, namely, 1".7. On Newton's corpuscular theory this should be only half as great. As a result of the measurements of the photographs of the eclipse of 1921 the number found was much nearer to the prediction of Einstein, and was inversely proportional to the distance from the center of the sun, in further confirmation of the theory. (3) The theory predicts a displacement of the solar spectral lines, and it seems that this prediction is also verified.

I remember the words of the great physicist Albert Einstein: A human being is part of the whole we call the universe, a part limited in time and space. He experiences himself in his thoughts and feelings as something separated from the rest . . . a kind of optical illusion of his consciousness. This illusion is a prison for us, restricting us to our personal desires and to affection for only the few people nearest us.

From time to time, we hear physicists claim that Einstein didn’t understand Quantum Mechanics and therefore wasted his time with naive classical theories. I very much doubt that this is true. His arguments against Quantum Mechanics were extremely subtle, culminating in one of the most profound and most cited papers in all of physics.12 My guess is that Einstein was disturbed by the same thing that bothered the slow student. How could the ultimate theory of reality be about nothing more concrete than our own degree of surprise at the outcome of an experiment?

Albert Einstein once said, “Most people say that it is the intellect which makes a great scientist. They are wrong: it is character.” . . . On one level, science is a collection of facts about the world, and adding to that collection does require discoveries. But science is also something larger. It’s a mindset, a process, a way of reasoning about the world that allows us to expose wishful thinking and biases and replace them with deeper, more reliable truths. Considering how vast the world is, there’s no way to check every reported experiment yourself and personally verify it. At some point, you have to trust other people’s claims—which means those people need to be honorable, need to be worthy of trusting. Moreover, science is an inherently social process. Results cannot be kept secret; they have to be verified by the wider community, or science simply doesn’t work. And given what a deeply social process science is, acts that damage society by shortchanging human rights or ignoring human dignity will almost always cost you in the end—by destroying people’s trust in science and even undermining the very conditions that make science possible.

On the Electrodynamics of Moving Bodies” Now let’s look at how Einstein articulated all of this in the famous paper that the Annalen der Physik received on June 30, 1905. For all its momentous import, it may be one of the most spunky and enjoyable papers in all of science. Most of its insights are conveyed in words and vivid thought experiments, rather than in complex equations. There is some math involved, but it is mainly what a good high school senior could comprehend. “The whole paper is a testament to the power of simple language to convey deep and powerfully disturbing ideas,” says the science writer Dennis Overbye.

In my entire scientific life, extending over forty-five years, the most shattering experience has been the realization that an exact solution of Einstein's equations of general relativity, discovered by the New Zealand mathematician Roy Kerr, provides the absolute exact representation of untold numbers of massive black holes that populate the universe. This "shuddering before the beautiful," this incredible fact that a discovery motivated by a search after the beautiful in mathematics should find its exact replica in Nature, persuades me to say that beauty is that to which the human mind responds at its deepest and most profound level.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead. ALBERT EINSTEIN I am made to love the pond and the meadow, as the wind is made to ripple the water. HENRY DAVID THOREAU I hold to the presupposition that our loss of the sense of aesthetic unity was, quite simply, an epistemological mistake. I believe that that mistake may be more serious than all the minor insanities that characterized those older epistemologies which agreed upon fundamental unity. GREGORY BATESON

Einstein’s doubts were only heightened when in 1927 Heisenberg published his paper on the central role of uncertainty in the quantum world. What he meant was that it is impossible to determine at any given moment both an entity’s precise position and its precise momentum: “We cannot know, as a matter of principle, the present in all its details.” Born agreed, and argued that the outcome of any quantum experiment depended on chance. In 1927, Einstein wrote Born: “An inner voice tells me that this is not the true Jacob. The theory accomplishes a lot, but it does not bring us closer to the secrets of the Old One. In any case, I am convinced that He does not play dice.

In some cases, the reaction to Cantor’s theory broke along national lines. French mathematicians, on the whole, were wary of its metaphysical aura. Henri Poincaré (who rivaled Germany’s Hilbert as the greatest mathematician of the era) observed that higher infinities “have a whiff of form without matter, which is repugnant to the French spirit.” Russian mathematicians, by contrast, enthusiastically embraced the newly revealed hierarchy of infinities. Why the contrary French and Russian reactions? Some observers have chalked it up to French rationalism versus Russian mysticism. That is the explanation proffered, for example, by Loren Graham, an American historian of science retired from MIT, and Jean-Michel Kantor, a mathematician at the Institut de Mathématiques de Jussieu in Paris, in their book Naming Infinity (2009). And it was the Russian mystics who better served the cause of mathematical progress—so argue Graham and Kantor. The intellectual milieu of the French mathematicians, they observe, was dominated by Descartes, for whom clarity and distinctness were warrants of truth, and by Auguste Comte, who insisted that science be purged of metaphysical speculation. Cantor’s vision of a never-ending hierarchy of infinities seemed to offend against both. The Russians, by contrast, warmed to the spiritual nimbus of Cantor’s theory. In fact, the founding figures of the most influential school of twentieth-century Russian mathematics were adepts of a heretical religious sect called the Name Worshippers. Members of the sect believed that by repetitively chanting God’s name, they could achieve fusion with the divine. Name Worshipping, traceable to fourth-century Christian hermits in the deserts of Palestine, was revived in the modern era by a Russian monk called Ilarion. In 1907, Ilarion published On the Mountains of the Caucasus, a book that described the ecstatic experiences he induced in himself while chanting the names of Christ and God over and over again until his breathing and heartbeat were in tune with the words.

A century ago, Albert Einstein revolutionised our understanding of space, time, energy and matter. We are still finding awesome confirmations of his predictions, like the gravitational waves observed in 2016 by the LIGO experiment. When I think about ingenuity, Einstein springs to mind. Where did his ingenious ideas come from? A blend of qualities, perhaps: intuition, originality, brilliance. Einstein had the ability to look beyond the surface to reveal the underlying structure. He was undaunted by common sense, the idea that things must be the way they seemed. He had the courage to pursue ideas that seemed absurd to others. And this set him free to be ingenious, a genius of his time and every other.

As Einstein once said, “One of the strongest motives that lead persons to art or science is a flight from the everyday life. . . . With this negative motive goes a positive one. Man seeks to form for himself, in whatever manner is suitable for him, a simplified and lucid image of the world, and so to overcome the world of experience by striving to replace it to some extent by this image. This is what the painter does, and the poet, the speculative philosopher, the natural scientist, each in his own way. Into this image and its formation, he places the center of gravity of his emotional life, in order to attain the peace and serenity that he cannot find within the narrow confines of swirling personal experience.

Einstein’s developmental problems have probably been exaggerated, perhaps even by himself, for we have some letters from his adoring grandparents saying that he was just as clever and endearing as every grandchild is. But throughout his life, Einstein had a mild form of echolalia, causing him to repeat phrases to himself, two or three times, especially if they amused him. And he generally preferred to think in pictures, most notably in famous thought experiments, such as imagining watching lightning strikes from a moving train or experiencing gravity while inside a falling elevator. “I very rarely think in words at all,” he later told a psychologist. “A thought comes, and I may try to express it in words afterwards.”4

The brain best remembers things that are repeated, rhythmic, rhyming, structured, and above all easily visualized. The principles that the oral bards discovered, as they sharpened their stories through telling and retelling, were the same basic mnemonic principles that psychologists rediscovered when they began conducting their first scientific experiments on memory around the turn of the twentieth century: Words that rhyme are much more memorable than words that don’t; concrete nouns are easier to remember than abstract nouns; dynamic images are more memorable than static images; alliteration aids memory. A striped skunk making a slam dunk is a stickier thought than a patterned mustelid engaging in athletic activity.

A human being is part of the whole, called by us “Universe,” a part limited in time and space. He experiences himself, his thoughts and feelings, as something separated from the rest—a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such an achievement is in itself a part of the liberation and a foundation for inner security. —Albert Einstein, as quoted in the New York Times, March 29, 1972

Ten years before understanding that time is slowed down by mass,21 Einstein had realized that it was slowed down by speed.22 The consequence of this discovery for our basic intuitive perception of time is the most devastating of all. The fact itself is quite simple. Instead of sending the two friends from the first chapter to the mountains and the plains, respectively, let’s ask one of them to stay still and the other one to walk around. Time passes more slowly for the one who keeps moving. As before, the two friends experience different durations: the one who moves ages less quickly, his watch marks less time passing; he has less time in which to think; the plant he is carrying takes longer to germinate, and so on. For everything that moves, time passes more slowly.

A century ago, Albert Einstein revolutionised our understanding of space, time, energy and matter. We are still finding awesome confirmations of his predictions, like the gravitational waves observed in 2016 by the LIGO experiment. When I think about ingenuity, Einstein springs to mind. Where did his ingenious ideas come from? A blend of qualities, perhaps: intuition, originality, brilliance. Einstein had the ability to look beyond the surface to reveal the underlying structure. He was undaunted by common sense, the idea that things must be the way they seemed. He had the courage to pursue ideas that seemed absurd to others. And this set him free to be ingenious, a genius of his time and every other. A key element for Einstein was imagination. Many of his discoveries came from his ability to reimagine the universe through thought experiments. At the age of sixteen, when he visualised riding on a beam of light, he realised that from this vantage light would appear as a frozen wave. That image ultimately led to the theory of special relativity. One hundred years later, physicists know far more about the universe than Einstein did. Now we have greater tools for discovery, such as particle accelerators, supercomputers, space telescopes and experiments such as the LIGO lab’s work on gravitational waves. Yet imagination remains our most powerful attribute. With it, we can roam anywhere in space and time. We can witness nature’s most exotic phenomena while driving in a car, snoozing in bed or pretending to listen to someone boring at a party.

Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next—and disappear. That’s why it’s important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives. William James first wrote about the curious warping and foreshortening of psychological time in his Principles of Psychology in 1890: “In youth we may have an absolutely new experience, subjective or objective, every hour of the day.

When we experience true compassion in our lives, our sense of separation between ourselves and others, all life, and the world, as well as within ourselves, disappears. Albert Einstein recognized the power of compassion in our lives, as well as the potential it holds to alleviate suffering. In his words, “Our task must be to free ourselves . . . by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.”10 The fourteenth Dalai Lama carried this understanding from personal healing to global survival, stating, “I truly believe that compassion provides the basis of human survival.”11 The recognition of compassion’s role in our lives opens the door to the depths of our greatest self-mastery and the extraordinary experiences that make us human.

When his support team on the surface finally called down to him on September 14, the day his experiment was scheduled to wrap up, it was only August 20 in his journal. He thought only a month had gone by. His experience of time’s passage had compressed by a factor of two. Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life, while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next—and disappear. That’s why it’s important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can serve to anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives.

The reciprocal relationship of epistemology and science is of noteworthy kind. They are dependent upon each other. Epistemology without contact with science becomes an empty scheme. Science without epistemology is—insofar as it is thinkable at all—primitive and muddled. However, no sooner has the epistemologist, who is seeking a clear system, fought his way through to such a system, than he is inclined to interpret the thought-content of science in the sense of his system and to reject whatever does not fit into his system. The scientist, however, cannot afford to carry his striving for epistemological systematic that far. He accepts gratefully the epistemological conceptual analysis; but the external conditions, which are set for him by the facts of experience, do not permit him to let himself be too much restricted in the construction of his conceptual world by the adherence to an epistemological system. He therefore must appear to the systematic epistemologist as a type of unscrupulous opportunist: he appears as realist insofar as he seeks to describe a world independent of the acts of perception; as idealist insofar as he looks upon the concepts and theories as free inventions of the human spirit (not logically derivable from what is empirically given); as positivist insofar as he considers his concepts and theories justified only to the extent to which they furnish a logical representation of relations among sensory experiences. He may even appear as Platonist or Pythagorean insofar as he considers the viewpoint of logical simplicity as an indispensable and effective tool of his research. (Einstein 1949, 683–684)

Then there occurred to me the 'glucklichste Gedanke meines Lebens,' the happiest thought of my life, in the following form. The gravitational field has only a relative existence in a way similar to the electric field generated by magnetoelectric induction. Because for an observer falling freely from the roof of a house there exists-at least in his immediate surroundings-no gravitational field [his italics]. Indeed, if the observer drops some bodies then these remain relative to him in a state of rest or of uniform motion, independent of their particular chemical or physical nature (in this consideration the air resistance is, of course, ignored). The observer therefore has the right to interpret his state as 'at rest.' Because of this idea, the uncommonly peculiar experimental law that in the gravitational field all bodies fall with the same acceleration attained at once a deep physical meaning. Namely, if there were to exist just one single object that falls in the gravitational field in a way different from all others, then with its help the observer could realize that he is ina gravitational field and is falling in it. If such an object does not exist, however-as experience has shown with great accuracy-then the observer lacks any objective means of perceiving himself as falling in a gravitational field. Rather he has the right to consider his state as one of rest and his environment as field-free relative to gravitation. The experimentally known matter independence of the acceleration of fall is therefore a powerful argument for the fact that the relativity postulate has to be extended to coordinate systems which, relative to each other, are in non-uniform motion.

William James first wrote about the curious warping and foreshortening of psychological time in his Principles of Psychology in 1890: “In youth we may have an absolutely new experience, subjective or objective, every hour of the day. Apprehension is vivid, retentiveness strong, and our recollections of that time, like those of a time spent in rapid and interesting travel, are of something intricate, multitudinous and long-drawn-out,” he wrote. “But as each passing year converts some of this experience into automatic routine which we hardly note at all, the days and the weeks smooth themselves out in recollection to contentless units, and the years grow hollow and collapse.” Life seems to speed up as we get older because life gets less memorable as we get older. “If to remember is to be human, then remembering more means being more human,” said Ed.

When I got home, I thought about the fact that Einstein supposedly used to stock his wardrobe with the same suits and shoes so he’d never have to think about what he was going to wear. I lack the intellect it takes to solve problems that way. I’ve advanced nothing in the field of psychology, and my paper on PTSD was given little attention; I wrote that psychological disorders with a genetic link, such as borderline personality disorder, might seem impossible to treat, while PTSD, which is based in trauma that has been experienced, seems easy to tackle, at least to the layperson. The opposite is true. It can be difficult to find the right medication for genetic disorders, but they can be sufficiently treated. Conversely, PTSD never goes away. One might think that our genes are so elementary that we cannot escape them, but our experiences have the ability to do far greater damage.

I still remember seeing a great, ancient maple send shudder after shudder through its trunk one year—for days on end. The entire tree was undulating; I’d never seen or felt anything like it before. Some dimension of the world that I had never encountered before was intruding itself into my experience. It literally felt like the underpinnings of my world view were crumbling. It seemed as if the tree were having an epileptic seizure, something far outside my experience of trees. Then, with a great crash one day, a single giant, diseased limb came hurtling down from the canopy, at which point the shudders ceased. In a flash of insight then, I understood that trees self-prune, that they self-caretake, that I had only the barest understanding of the plant world and finally grasped Einstein’s observation that “we still do not know one thousandth of one percent of what nature has revealed to us.

In one of our early conversations, Bob said to me, "I like Einstein as a character, because everybody knows who he is." In a sense, we didn't need to tell an Einstein story because everybody who eventually saw our Einstein brought their own story with them. In the four months that we toured Einstein in Europe we had many occasions to meet with our audiences, and people occasionally would ask us what it "meant." But far more often people told us what it meant to them, sometimes even giving us plot elucidation and complete scenario. The point about Einstein was clearly not what it "meant" but that it was meaningful as generally experienced by the people who saw it. From the viewpoint of the creators, of course, that is exactly the way it was constructed to work. Though we made no attempt at all to tell a story, we did use dramaturgical devices to create a clearly paced overall dramatic shape. For instance, a "finale" is a dramaturgical device; an "epilogue" is another. Using contrasting sections, like a slow trial scene followed by a fast dance scene, is a dramaturgical device, and we used such devices freely. I am sure that the absence of direct connotative "meaning" made it all the easier for the spectator to personalize the experience by supplying his own special "meaning" out of his own experience, while the work itself remained resolutely abstract. As to the use of three visual schemes, or images, Bob often mentioned that he envisioned them in three distinct ways: (1) a landscape seen at a distance (the Field/Spaceship scenes); (2) still lifes seen at a middle distance (the Trial scenes); and (3) portraits seen as in a closeup (the Knee Plays). As these three perspectives rotated through the four acts of the work, they created the sequence of images in an ordered scale. Furthermore, the recurrence of the images implied a kind of quasi-development. For example, the sequence of Train scenes from the Act I, scene 1 Train, to the "night train" of Act II and finally the building which resembled in perspective the departing night train, presented that sequence of images in a reductive order (each one became less "train-like") and at the same time more focused and energized. The same process applies to the sequence of Trial scenes (ending with a bar of light representing the bed) as well as the Field/Spaceship, with the final scene in the interior of the spaceship serving as a kind of apocalyptic grand finale of the whole work. Each time an image reappeared, it was altered to become more abstract and, oddly enough, more powerful. The way these three sequences were intercut with each other, as well as with the portrait-scale Knee Plays, served to heighten the dramatic effect.

But as they walked out to the parking lot, Einstein suddenly appeared and Oppenheimer stopped to chat with him. Hobson sat in the car while the two men talked, and when Oppie returned to the car, he told her, “Einstein thinks that the attack on me is so outrageous that I should just resign.” Perhaps recalling his own experience in Nazi Germany, Einstein argued that Oppenheimer “had no obligation to subject himself to the witch-hunt, that he had served his country well, and that if this was the reward she [America] offered he should turn his back on her.” Hobson vividly remembered Oppenheimer’s reaction: “Einstein doesn’t understand.” Einstein had fled his homeland as it was about to be overwhelmed by the Nazi contagion—and he refused ever again to set foot in Germany. But Oppenheimer could not turn his back on America. “He loved America,” Hobson later insisted. “And this love was as deep as his love of science.

Many people have difficulty contemplating the human soul. They think that an immortal, massless entity with no dimensions that exists outside space and time is inherently preposterous. But they are perfectly willing to accept the existence of light. Yet what is light? Einstein’s special theory of relativity says that it is an immortal, massless entity with no dimensions that exists outside space and time. Hasn’t the penny dropped yet? Since Einstein, we have had scientific proof, verified by countless experiments, that something completely uncontroversial and unquestioned – light – has exactly the “physical” attributes commonly assigned to the soul. So, is it any longer tenable to assert that the concept of the soul is scientifically ridiculous? If it is then the concept of light must be equally ridiculous. If we took one further step of attributing mind to light, the theory of light would become the theory of souls.

A falsifiable theory is one that makes a specific prediction about what results are supposed to occur under a set of experimental conditions, so that the theory might be falsified by performing the experiment and comparing predicted to actual results. A theory or explanation that cannot be falsified falls outside the domain of science. For example, Freudian psychoanalysis, which does not make specific experimental predictions, is able to revise its theory to match any observations, in order to avoid rejecting the theory altogether. By this reckoning, Freudianism is a pseudoscience, a theory that purports to be scientific but is in fact immune to falsification. In contrast, for example, Einstein’s theory of relativity made predictions (like the bending of starlight around the sun) that were novel and specific, and provided opportunities to disprove the theory by direct experimental observation. [The folly of scientism]

During an individual's immersion in a domain, the locus of flow experiences shifts: what was once too challenging becomes attainable and even pleasurable, while what has long since become attainable no longer proves engaging. Thus, the journeyman musical performer gains flow from the accurate performance of familiar pieces in the repertoire; the youthful master wishes to tackle the most challenging pieces, ones most difficult to execute in a technical sense; the seasoned master may develop highly personal interpretations of familiar pieces, or, alternatively, return to those deceptively simple pieces that may actually prove difficult to execute convincingly and powerfully. Such an analysis helps explain why creative individuals continue to engage in the area of their expertise despite its frustrations, and why so many of them continue to raise the ante, posing ever-greater challenges for themselves, even at the risk of sacrificing the customary rewards.

Embracing a different vocabulary, Mihaly Csikszentmihalyi has described a highly sought-after affective state called the flow state or flow experience. In such intrinsically motivating experiences, which can occur in any domain of activity, people report themselves as fully engaged with and absorbed by the object of their attention. In one sense, those "in flow" are not conscious of the experience at the moment; on reflection, however, such people feel that they have been fully alive, totally realized, and involved in a "peak experience." Individuals who regularly engage in creative activities often report that they seek such states; the prospect of such "periods of flow" can be so intense that individuals will exert considerable practice and effort, and even tolerate physical or psychological pain, in pursuit thereof. Committed writers may claim that they hate the time spent chained to their desks, but the thought that they would not have the opportunity to attain occasional periods of flow while writing proves devastating.

The extraordinary value of the I Ching is that it reveals the secrets of dynamic natural law. Working with its changes opens up access to the middle level of the Positive Paradigm Wheel, the “e” energy layer of Einstein's Unified Theory. This middle level serves as mediating, two-directional gate-keeper between the ever-changing surface rim and the universal, timeless center. You can't get from here to there, except through the middle layer which, in Western thinking, is effectively taboo, buried in the inaccessible "unconscious." To the extent that natural law is a blind spot in the prevailing, linear and exclusively empirical paradigm, we are left powerless to move beyond the surface level of experience. The realm of light and conscience which rests beyond, on the far side of the dynamic energy level, remains functionally inaccessible. Moral codes promoted by religionists or politicians are sometimes equated with conscience. But they're no substitute for direct experience. Only by becoming intelligently competent in managing the subtle energies of the middle level is it possible to travel further inwards for the immediate, personal experience of inner light. When the middle level becomes clogged with painful memories, negative emotions and socially taboo urges, it becomes a barrier to deeper knowing. The Book of Change is indispensable as a tool for restoring the unnecessarily "unconscious" to conscious awareness, so that the levels of human potential can be linked and unified. In Positive Paradigm context, survivors who prevail in dangerous times aren't those with the most material wealth, possessions or political power. They're the ones who've successfully navigated the middle realm, reached the far shore of enlightenment and returned to the surface with their new information intact. Those who succeed in linking the levels of experience are genius-leaders in whatever fields they choose to engage. They're the fortunate ones who've acquired the inner wealth necessary to both hear the inner voice of conscience and act on the guidance they receive.

Einstein felt that he did not have great mathematical gifts and deliberately chose not to take courses and to continue in that area. The fact that I neglected mathematics to a certain extent had its causes not merely in my stronger interest in science than in mathematics but also in the following strange experience....I saw that mathematics was split up into numerous specialties, each of which could easily absorb the short lifetime granted to us....In physics, however, I soon learned to scent out that which was able to lead to fundamentals and to turn aside from everything else, from the multitude of things that clutter up the mind and divert it from the essential. This capacity to pick out important issues dovetailed with Einstein's search for the most general possible conception. "In a man of my type," he declared, "the turning point of the development lies in the fact that gradually the major interest disengages itself to a far reaching degree from the momentary and the merely personal and turns toward the striving for a mental grasp of things.

There were also many cases of feedback between physics and mathematics, where a physical phenomenon inspired a mathematical model that later proved to be the explanation of an entirely different physical phenomenon. An excellent example is provided by the phenomenon known as Brownian motion. In 1827, British botanist Robert Brown (1773-1858) observed that wen pollen particles are suspended in water, they get into a state of agitated motion. This effect was explained by Einstein in 1905 as resulting from the collisions that the colloidal particles experience with the molecules of the surrounding fluid. Each single collision has a negligible effect, because the pollen grains are millions of times more massive than the water molecules, but the persistent bombardment has a cumulative effect. Amazingly, the same model was found to apply to the motions of stars in star clusters. There the Brownian motion is produced by the cumulative effect of many stars passing by any given star, with each passage altering the motion (through gravitational interaction) by a tiny amount.

Saint John Paul II wrote, “when its concepts and conclusions can be integrated into the wider human culture and its concerns for ultimate meaning and value.”7 Religion, too, develops best when its doctrines are not abstract and fixed in an ancient past but integrated into the wider stream of life. Albert Einstein once said that “science without religion is lame and religion without science is blind.”8 So too, John Paul II wrote: “Science can purify religion from error and superstition; religion can purify science from idolatry and false absolutes. Each can draw the other into a wider world, a world in which both can flourish.”9 Teilhard de Chardin saw that dialogue alone between the disciplines is insufficient; what we need is a new synthesis of science and religion, drawing insights from each discipline into a new unity. In a remarkable letter to the director of the Vatican Observatory, John Paul II wrote: The church does not propose that science should become religion or religion science. On the contrary, unity always presupposes the diversity and integrity of its elements. Each of these members should become not less itself but more itself in a dynamic interchange, for a unity in which one of the elements is reduced to the other is destructive, false in its promises of harmony, and ruinous of the integrity of its components. We are asked to become one. We are not asked to become each other. . . . Unity involves the drive of the human mind towards understanding and the desire of the human spirit for love. When human beings seek to understand the multiplicities that surround them, when they seek to make sense of experience, they do so by bringing many factors into a common vision. Understanding is achieved when many data are unified by a common structure. The one illuminates the many: it makes sense of the whole. . . . We move towards unity as we move towards meaning in our lives. Unity is also the consequence of love. If love is genuine, it moves not towards the assimilation of the other but towards union with the other. Human community begins in desire when that union has not been achieved, and it is completed in joy when those who have been apart are now united.10 The words of the late pope highlight the core of catholicity: consciousness of belonging to a whole and unity as a consequence of love.

As you know, there was a famous quarrel between Max Planck and Einstein, in which Einstein claimed that, on paper, the human mind was capable of inventing mathematical models of reality. In this he generalized his own experience because that is what he did. Einstein conceived his theories more or less completely on paper, and experimental developments in physics proved that his models explained phenomena very well. So Einstein says that the fact that a model constructed by the human mind in an introverted situation fits with outer facts is just a miracle and must be taken as such. Planck does not agree, but thinks that we conceive a model which we check by experiment, after which we revise our model, so that there is a kind of dialectic friction between experiment and model by which we slowly arrive at an explanatory fact compounded of the two. Plato-Aristotle in a new form! But both have forgotten something- the unconscious. We know something more than those two men, namely that when Einstein makes a new model of reality he is helped by his unconscious, without which he would not have arrived at his theories...But what role DOES the unconscious play?...either the unconscious knows about other realities, or what we call the unconscious is a part of the same thing as outer reality, for we do not know how the unconscious is linked with matter.

It might be imagined that certain people in history—the naturally gifted, the geniuses—have either somehow bypassed the Apprenticeship Phase or have greatly shortened it because of their inherent brilliance. To support such an argument, people will bring up the classic examples of Mozart and Einstein, who seemed to have emerged as creative geniuses out of nowhere. With the case of Mozart, however, it is generally agreed among classical music critics that he did not write an original and substantial piece of music until well after ten years of composing. In fact, a study of some seventy great classical composers determined that with only three exceptions, all of the composers had needed at least ten years to produce their first great work, and the exceptions had somehow managed to create theirs in nine years. Einstein began his serious thought experiments at the age of sixteen. Ten years later he came up with his first revolutionary theory of relativity. It is impossible to quantify the time he spent honing his theoretical skills in those ten years, but is not hard to imagine him working three hours a day on this particular problem, which would yield more than 10,000 hours after a decade. What in fact separates Mozart and Einstein from others is the extreme youth with which they began their apprenticeships and the intensity with which they practiced, stemming from their total immersion in the subject. It is often the case that in our younger years we learn faster, absorb more deeply, and yet retain a kind of creative verve that tends to fade as we get older.

Using magnetoencephalography, a technique that measures the weak magnetic fields given off by a thinking brain, researchers have found that higher-rated chess players are more likely to engage the frontal and parietal cortices of the brain when they look at the board, which suggests that they are recalling information from long-term memory. Lower-ranked players are more likely to engage the medial temporal lobes, which suggests that they are encoding information. The experts are interpreting the present board in terms of their massive knowledge of past ones. The lower ranked players are seeing the board as something new...[de Groot] argued that expertise in the field of shoemaking, painting, building, or confectionary, is the result of the same accumulation of experiential linkings. According to Erikson, what we call expertise is really just vast amounts of knowledge, pattern-based retrieval, and planning mechanisms acquired over many years of experience in the associated domain. In other words, a great memory isn't just a byproduct of expertise; it is the essence of expertise. Whether we realize it or not, we are all like those chess masters and chicken sexers- interpreting the present in light of what we've learned in the past and letting our previous experiences shape not only how we perceive our world, but also the moves we end up making in it... Our memories are always with us, shaping and being shaped by the information flowing through our senses in a continuous feedback loop. Everything we see, hear, and smell is inflected by all the things we've seen, heard, and smelled in the past...Who we are and what we do is fundamentally a function of what we remember.

If you cannot drop a wrong problem, then the first time you meet one you will be stuck with it for the rest of your career. Einstein was tremendously creative in his early years, but once he began, in midlife, the search for a unified theory, he spent the rest of his life on it and had about nothing to show for all the effort. I have seen this many times while watching how science is done. It is most likely to happen to the very creative people; their previous successes convince them they can solve any problem, but there are other reasons besides overconfidence why, in many fields, sterility sets in with advancing age. Managing a creative career is not an easy task, or else it would often be done. In mathematics, theoretical physics, and astrophysics, age seems to be a handicap (all characterized by high, raw creativity), while in music composition, literature, and statesmanship, age and experience seem to be an asset. As valued by Bell Telephone Laboratories in the late 1970s, the first 15 years of my career included all they listed, and for my second 15 years they listed nothing I was very closely associated with! Yes, in my areas the really great things are generally done while the person is young, much as in athletics, and in old age you can turn to coaching (teaching), as I have done. Of course, I do not know your field of expertise to say what effect age will have, but I suspect really great things will be realized fairly young, though it may take years to get them into practice. My advice is if you want to do significant things, now is the time to start thinking (if you have not already done so) and not wait until it is the proper moment—which may never arrive!

Wheeler wasn’t the first to point out that quantum mechanics slips into paradox the minute you introduce a second observer. The Nobel Prize–winning physicist Eugene Wigner, for one, had emphasized it with a Schrödinger’s-cat-style thought experiment that became known as “Wigner’s friend.” It went something like this: Inside a lab, Wigner’s friend sets up an experiment in which an atom will randomly emit a photon, producing a flash of light that leaves a spot on a photographic plate. Before Wigner’s friend checks the plate for signs of a flash, quantum mechanics shows that the atom is in a superposition of having emitted a photon and not having emitted a photon. Once the friend looks at the plate, however, he sees a single outcome—the atom flashed or it didn’t. Somehow his looking collapses the atom’s wavefunction, transforming two possibilities into a single reality. Wigner, meanwhile, is standing outside the lab. From his point of view, quantum mechanics shows that until his friend tells him the outcome of the experiment, the atom remains in a superposition of having emitted a photon and not having emitted a photon. What’s more, his friend is now in a superposition of having seen a spot of light on the plate and not having seen a spot of light on the plate. Only Wigner, quantum theory says, can collapse the wavefunction by asking his friend what happened in there. The two stories are contradictory. According to Wigner’s friend, the atom’s wavefunction collapsed when he looked at the plate. According to Wigner, it didn’t. Instead, his friend entered a superposition correlated with the superposition of the atom, and it wasn’t until Wigner spoke to his friend that both superpositions collapsed. Which story is right? Who is the true creator of reality, Wigner or his friend?

Trying to trick the creature, hoping that it would react without hesitation to the first sign of movement in the door way, Travis tucked the revolver under his belt, quietly picked up one of the dining-room chairs, eased to within six feet of the kitchen, and pitched the chair through the open door. He snatched the revolver out of his waistband and, as the chair sailed into the kitchen, assumed a shooter's stance. The chair crashed into the Formica-topped table, clattered to the floor, and banged against the dishwasher. The lantern-eyed enemy did not go for it. Nothing moved. When the chair finished tumbling, the kitchen was again marked by a hushed expectancy . Einstein was making a curious sound, a quiet shuddery huffing, and after a moment Travis realized the noise was a result of the dog's uncontrollable shivering. No question about it: the intruder in the kitchen was the very thing that had pursued them through the woods more than three months ago. During the intervening weeks, it had made its way north, probably traveling mostly in the wildlands to the east of the developed part of the state, relentlessly tracking the dog by some means that Travis could not understand and for reasons he could not even guess. In response to the chair he had thrown, a large white-enameled canister crashed to the floor just beyond the kitchen doorway, and Travis jumped back in surprise, squeezing off a wild shot before he realized he was only being taunted. The lid flew off the container when it hit the floor, and flour spilled across the tile. Silence again. By responding to Travis's taunt with one of its own, the intruder had displayed unnerving intelligence. Abruptly Travis realized that, coming from the same research lab as Einstein and being a product of related experiments, the creature might be as smart as the retriever. Which would explain Einstein's fear of it. If Travis had not already accommodated himself to the idea of a dog with humanlike intelligence, he might have been unable to credit this beast with more than mere animal cleverness; however, events of the past few months had primed him to accept-and quickly adapt to-almost anything.

The traditional hospital practice of excluding parents ignored the importance of attachment relationships as regulators of the child’s emotions, behaviour and physiology. The child’s biological status would be vastly different under the circumstances of parental presence or absence. Her neurochemical output, the electrical activity in her brain’s emotional centres, her heart rate, blood pressure and the serum levels of the various hormones related to stress would all vary significantly. Life is possible only within certain well-defined limits, internal or external. We can no more survive, say, high sugar levels in our bloodstream than we can withstand high levels of radiation emanating from a nuclear explosion. The role of self-regulation, whether emotional or physical, may be likened to that of a thermostat ensuring that the temperature in a home remains constant despite the extremes of weather conditions outside. When the environment becomes too cold, the heating system is switched on. If the air becomes overheated, the air conditioner begins to work. In the animal kingdom, self-regulation is illustrated by the capacity of the warm-blooded creature to exist in a broad range of environments. It can survive more extreme variations of hot and cold without either chilling or overheating than can a coldblooded species. The latter is restricted to a much narrower range of habitats because it does not have the capacity to self-regulate the internal environment. Children and infant animals have virtually no capacity for biological self-regulation; their internal biological states—heart rates, hormone levels, nervous system activity — depend completely on their relationships with caregiving grown-ups. Emotions such as love, fear or anger serve the needs of protecting the self while maintaining essential relationships with parents and other caregivers. Psychological stress is whatever threatens the young creature’s perception of a safe relationship with the adults, because any disruption in the relationship will cause turbulence in the internal milieu. Emotional and social relationships remain important biological influences beyond childhood. “Independent self-regulation may not exist even in adulthood,” Dr. Myron Hofer, then of the Departments of Psychiatry and Neuroscience at Albert Einstein College of Medicine in New York, wrote in 1984. “Social interactions may continue to play an important role in the everyday regulation of internal biologic systems throughout life.” Our biological response to environmental challenge is profoundly influenced by the context and by the set of relationships that connect us with other human beings. As one prominent researcher has expressed it most aptly, “Adaptation does not occur wholly within the individual.” Human beings as a species did not evolve as solitary creatures but as social animals whose survival was contingent on powerful emotional connections with family and tribe. Social and emotional connections are an integral part of our neurological and chemical makeup. We all know this from the daily experience of dramatic physiological shifts in our bodies as we interact with others. “You’ve burnt the toast again,” evokes markedly different bodily responses from us, depending on whether it is shouted in anger or said with a smile. When one considers our evolutionary history and the scientific evidence at hand, it is absurd even to imagine that health and disease could ever be understood in isolation from our psychoemotional networks. “The basic premise is that, like other social animals, human physiologic homeostasis and ultimate health status are influenced not only by the physical environment but also by the social environment.” From such a biopsychosocial perspective, individual biology, psychological functioning and interpersonal and social relationships work together, each influencing the other.

When he applied this approach to a gas of quantum particles, Einstein discovered an amazing property: unlike a gas of classical particles, which will remain a gas unless the particles attract one another, a gas of quantum particles can condense into some kind of liquid even without a force of attraction between them. This phenomenon, now called Bose-Einstein condensation,* was a brilliant and important discovery in quantum mechanics, and Einstein deserves most of the credit for it. Bose had not quite realized that the statistical mathematics he used represented a fundamentally new approach. As with the case of Planck’s constant, Einstein recognized the physical reality, and the significance, of a contrivance that someone else had devised.49 Einstein’s method had the effect of treating particles as if they had wavelike traits, as both he and de Broglie had suggested. Einstein even predicted that if you did Thomas Young’s old double-slit experiment (showing that light behaved like a wave by shining a beam through two slits and noting the interference pattern) by using a beam of gas molecules, they would interfere with one another as if they were waves. “A beam of gas molecules which passes through an aperture,” he wrote, “must undergo a diffraction analogous to that of a light ray.

Einstein’s first public collision with this anti-Semitism came in the summer of 1920. A shady German nationalist named Paul Weyland, an engineer by training, had turned himself into a polemicist with political aspirations. He was an active member of a right-wing nationalistic political party that pledged, in its 1920 official program, to “diminish the dominant Jewish influence showing up increasingly in government and in public.”9 Weyland realized that Einstein, as a highly publicized Jew, had engendered resentment and jealousy. Likewise, his relativity theory was easy to turn into a target, because many people, including some scientists, were unnerved by the way it seemed to undermine absolutes and be built on abstract hypotheses rather than grounded in solid experiment. So Weyland published articles denouncing relativity as “a big hoax” and formed a ragtag (but mysteriously well-funded) organization grandly dubbed the Study Group of German Scientists for the Preservation of a Pure Science. Joining with Weyland was an experimental physicist of modest reputation named Ernst Gehrcke, who for years had been assailing relativity with more vehemence than comprehension. Their group lobbed a few personal attacks at Einstein and the “Jewish nature” of relativity theory, then called a series of meetings around Germany, including a large rally at Berlin’s Philharmonic Hall on August 24.

theory. “The development of the general theory of relativity introduced Einstein to the power of abstract mathematical formalisms, notably that of tensor calculus,” writes the astrophysicist John Barrow. “A deep physical insight orchestrated the mathematics of general relativity, but in the years that followed the balance tipped the other way. Einstein’s search for a unified theory was characterized by a fascination with the abstract formalisms themselves.”44 In his Oxford lecture, Einstein began with a nod to empiricism: “All knowledge of reality starts from experience and ends in it.” But he immediately proceeded to emphasize the role that “pure reason” and logical deductions play. He conceded, without apology, that his success using tensor calculus to come up with the equations of general relativity had converted him to a faith in a mathematical approach, one that emphasized the simplicity and elegance of equations more than the role of experience. The fact that this method paid off in general relativity, he said, “justifies us in believing that nature is the realization of the simplest conceivable mathematical ideas.”45 That is an elegant—and also astonishingly interesting—creed. It captured the essence of Einstein’s thought during the decades when mathematical “simplicity” guided him in his search for a unified field theory. And it echoed the great Isaac Newton’s declaration in book 3 of the Principia: “Nature is pleased with simplicity.” But Einstein offered no proof of this creed, one that seems belied by modern particle physics.46 Nor did he ever fully explain what, exactly, he meant by mathematical simplicity. Instead, he merely asserted his deep intuition that this is the way God would make the universe. “I am convinced that we can discover by means of purely mathematical constructions the concepts and the laws connecting them with each other,” he claimed.

Dunne’s dreams seemed to him evidence for what Einstein and other physicists and mathematicians were just beginning to assert: that since the present moment depends entirely on where you stand in relation to events—what might be in the past for one observer may still be in the future for another observer, and vice versa—then the future must in some sense already exist. Einstein’s theory of relativity suggested that time was a dimension like space. To help visualize this, his teacher, Hermann Minkowski, pictured “spacetime” as a four-dimensional block. For the purposes of this book, let’s make it a glass block so we can see what is happening inside it. One’s life, and the “life” of any single object or atom in the universe, is really a line—a “world line”—snaking spaghetti-like through that glass block. The solid three-dimensional “you” that you experience at any moment is really just a slice or cross section of a four-dimensional clump of spaghetti-like atoms that started some decades ago as a zygote, gradually expanded in size by incorporating many more spaghetti-strand atoms, and then, after several decades of coherence (as a literal “flying spaghetti monster”) will dissipate into a multitude of little spaghetti atoms going their separate ways after your death. (They will recoalesce in different combinations with other spaghetti-strand atoms to make other objects and other spaghetti beings, again and again and again, until the end of the universe.) What we perceive at any given moment as the present state of affairs is just a narrow slice or cross-section of that block as our consciousness traverses our world-line from beginning to end. (If it helps envision this, the comic artist, occult magician, and novelist Alan Moore has recently revised the “block” to a football—one tip being the big bang, the other the “big crunch” proposed in some cosmological models.32 I will stick with the term “glass block” since I am not a football fan and “glass football” sounds odd.) Precognitive dreams, Dunne argued, show that at night, as well as other times when the brain is in a relaxed state, our consciousness can wriggle free of the present moment and scan ahead (as well as behind) on our personal world-line, like a flashlight at night illuminating a spot on the path ahead. This ability to be both rooted mentally in our body, with its rich sensory “now,” and the possibility of coming unstuck in time (as Vonnegut put it) suggested to Dunne that human consciousness was dual. We not only possess an “individual mind” that adheres to the brain at any given time point, but we also are part of a larger, “Universal Mind,” that transcends the now and that spaghetti-clump body. The Universal Mind, he argued, is ultimately shared—a consciousness-in-common—that is equivalent to what has always been called “God.

Newton had conceived of light as primarily a stream of emitted particles. But by Einstein’s day, most scientists accepted the rival theory, propounded by Newton’s contemporary Christiaan Huygens, that light should be considered a wave. A wide variety of experiments had confirmed the wave theory by the late nineteenth century. For example, Thomas Young did a famous experiment, now replicated by high school students, showing how light passing through two slits produces an interference pattern that resembles that of water waves going through two slits. In each case, the crests and troughs of the waves emanating from each slit reinforce each other in some places and cancel each other out in some places.

Einstein further confused the issue in the last few years of his life by giving a series of statements on the subject to a physicist named Robert Shankland. At first he said he had read of Michelson-Morley only after 1905, then he said he had read about it in Lorentz’s book before 1905, and finally he added, “I guess I just took it for granted that it was true.”23 That final point is the most significant one because Einstein made it often. He simply took for granted, by the time he started working seriously on relativity, that there was no need to review all the ether-drift experiments because, based on his starting assumptions, all attempts to detect the ether were doomed to failure.24 For him, the significance of these experimental results was to reinforce what he already believed: that Galileo’s relativity principle applied to light waves.

The concept of absolute time—meaning a time that exists in “reality” and tick-tocks along independent of any observations of it—had been a mainstay of physics ever since Newton had made it a premise of his Principia 216 years earlier. The same was true for absolute space and distance. “Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external,” he famously wrote in Book 1 of the Principia. “Absolute space, in its own nature, without relation to anything external, remains always similar and immovable.” But even Newton seemed discomforted by the fact that these concepts could not be directly observed. “Absolute time is not an object of perception,” he admitted. He resorted to relying on the presence of God to get him out of the dilemma. “The Deity endures forever and is everywhere present, and by existing always and everywhere, He constitutes duration and space.”45 Ernst Mach, whose books had influenced Einstein and his fellow members of the Olympia Academy, lambasted Newton’s notion of absolute time as a “useless metaphysical concept” that “cannot be produced in experience.” Newton, he charged, “acted contrary to his expressed intention only to investigate actual facts.”46 Henri Poincaré also pointed out the weakness of Newton’s concept of absolute time in his book Science and Hypothesis, another favorite of the Olympia Academy. “Not only do we have no direct intuition of the equality of two times, we do not even have one of the simultaneity of two events occurring in different places,” he wrote.

One of Einstein’s clearest explanations of what he had wrought was in a letter to his Olympia Academy colleague Solovine: The theory of relativity can be outlined in a few words. In contrast to the fact, known since ancient times, that movement is perceivable only as relative movement, physics was based on the notion of absolute movement. The study of light waves had assumed that one state of movement, that of the light-carrying ether, is distinct from all others. All movements of bodies were supposed to be relative to the light-carrying ether, which was the incarnation of absolute rest. But after efforts to discover the privileged state of movement of this hypothetical ether through experiments had failed, it seemed that the problem should be restated. That is what the theory of relativity did. It assumed that there are no privileged physical states of movement and asked what consequences could be drawn from this.

Einstein’s insight, as he explained it to Solovine, was that we must discard concepts that “have no link with experience,” such as “absolute simultaneity” and “absolute speed.”61 It is very important to note, however, that the theory of relativity does not mean that “everything is relative.” It does not mean that everything is subjective. Instead, it means that measurements of time, including duration and simultaneity, can be relative, depending on the motion of the observer. So can the measurements of space, such as distance and length. But there is a union of the two, which we call spacetime, and that remains invariant in all inertial frames. Likewise, there are things such as the speed of light that remain invariant. In

Once again, he was deducing a theory from principles and postulates, not trying to explain the empirical data that experimental physicists studying cathode rays had begun to gather about the relation of mass to the velocity of particles. Coupling Maxwell’s theory with the relativity theory, he began (not surprisingly) with a thought experiment. He calculated the properties of two light pulses emitted in opposite directions by a body at rest. He then calculated the properties of these light pulses when observed from a moving frame of reference. From this he came up with equations regarding the relationship between speed and mass. The result was an elegant conclusion: mass and energy are different manifestations of the same thing. There is a fundamental interchangeability between the two. As he put it in his paper, “The mass of a body is a measure of its energy content.” The formula he used to describe this relationship was also strikingly simple: “If a body emits the energy L in the form of radiation, its mass decreases by L/V 2.” Or, to express the same equation in a different manner: L=mV 2. Einstein used the letter L to represent energy until 1912, when he crossed it out in a manuscript and replaced it with the more common E. He also used V to represent the velocity of light, before changing to the more common c. So, using the letters that soon became standard, Einstein had come up with his memorable equation: E=mc2

Einstein refined his thought experiment so that the falling man was in an enclosed chamber, such as an elevator in free fall above the earth. In this falling chamber (at least until it crashed), the man would feel weightless. Any objects he emptied from his pocket and let loose would float alongside him. Looking at it another way, Einstein imagined a man in an enclosed chamber floating in deep space “far removed from stars and other appreciable masses.” He would experience the same perceptions of weightlessness. “Gravitation naturally does not exist for this observer. He must fasten himself with strings to the floor, otherwise the slightest impact against the floor will cause him to rise slowly towards the ceiling.

The most beautiful emotion we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of all true art and science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead, a snuffed-out candle. To sense that behind anything that can be experienced there is something that our minds cannot grasp, whose beauty and sublimity reaches us only indirectly: this is religiousness. In this sense, and in this sense only, I am a devoutly religious man.

Pure logical thinking cannot yield us any knowledge of the empirical world. All knowledge of reality starts from experience and ends in it.

The only justification for our concepts and systems of concepts is that they serve to represent the complex of our experiences; beyond this they have no legitimacy.

But this result [that light would travel faster towards a moving observer] comes into conflict with the principle of relativity [the laws of physics are the same for all observers]", Einstein added. "For, like every other general law of nature, the law of the transmission of light must, according to the principle of relativity, be the same when the railway carriage is the reference body as it is when the enbamkment is the refernece body". [...] There should be no experiment you can do, including measuring the speed of light, to distinguish which inertial frame of refence is "at rest" and which is moving at a constant velocity.

One day during the 1930s, Einstein invited Saint-John Perse to Princeton to find out how the poet worked. “How does the idea of a poem come?” Einstein asked. The poet spoke of the role played by intuition and imagination. “It’s the same for a man of science,” Einstein responded with delight. “It is a sudden illumination, almost a rapture. Later, to be sure, intelligence analyzes and experiments confirm or invalidate the intuition. But initially there is a great forward leap of the imagination.”16 There was an aesthetic to Einstein’s thinking, a sense of beauty. And one component to beauty, he felt, was simplicity. He had echoed Newton’s dictum “Nature is pleased with simplicity” in the creed he declared at Oxford the year he left Europe for America: “Nature is the realization of the simplest conceivable mathematical ideas.

A human being is a spatially and temporally limited piece of the whole, what we call the ‘Universe.’ He experiences himself and his feelings as separate from the rest, [but that’s] an optical illusion of his consciousness. —Albert Einstein

Speed is measured as distance divided by time (miles per hour or meters per second). For the speed of light to remain constant, distance and time have to change. Let’s go back now to Galileo’s shipboard experiment, using a beam of light instead of a stone. On a boat that’s moving at a uniform speed across the water, shine a flashlight down the mast, and it will strike the deck at the base of the mast. The observer on the dock agrees with that. But from her vantage point on the dock, if she had a precision measuring tool, she would see the light travel a tiny extra distance, the distance the ship has moved in the time it took the light to reach the bottom of the mast. But the speed of light, which is measured in meters per second—again, distance divided by time—is a constant. So if the observer on the dock finds that light traveled an extra distance, the only way its speed can remain constant is if the light also took a longer time to travel. Time, therefore, is not immutable. The duration of time— measured as the ticks of a clock—is dif­ferent for observers who move at dif­ferent speeds. Each sees the other’s clock slow down. Even more strangely, distance is not absolute either; it appears to contract in the direction of motion.

By the “mysterious,” I do not think Einstein was referring to something fearful or supernatural. I believe he was speaking about the boundary between the known and the unknown. Standing at that boundary is an exhilarating experience. And it is a deeply human experience—concerning what the human mind understands and what that mind does not yet understand.
