Albert Einstein Relativity Quotes

When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.

Time is an illusion.

If my theory of relativity is proven successful, Germany will claim me as a German and France will declare me a citizen of the world. Should my theory prove untrue, France will say that I am a German, and Germany will declare that I am a Jew.

Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity.

Since the mathematicians have invaded the theory of relativity I do not understand it myself any more.

No matter how old you are now. You are never too young or too old for success or going after what you want.

Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.

The future is not a gift-it is an achievement.

Philosophers play with the word, like a child with a doll. It does not mean that everything in life is relative.

Science can only ascertain what is, but not what should be, and outside of its domain value, elly judgments of all kinds remain necessary.

If you've never done anything wrong it's probably because you have never tried anything new.

Honestly, I cannot understand what people mean when they talk about the freedom of the human will. I have a feeling, for instance, that I will something or other; but what relation this has with freedom I cannot understand at all. I feel that I will to light my pipe and I do it; but how can I connect this up with the idea of freedom? What is behind the act of willing to light the pipe? Another act of willing? Schopenhauer once said: Der Mensch kann was er will; er kann aber nicht wollen was er will (Man can do what he will but he cannot will what he wills).

Dear Habicht, / Such a solemn air of silence has descended between us that I almost feel as if I am committing a sacrilege when I break it now with some inconsequential babble... / What are you up to, you frozen whale, you smoked, dried, canned piece of soul...?

Time is relative; its only worth depends upon what we do as it is passing.

Asked in 1919 whether it was true that only three people in the world understood the theory of general relativity, [Eddington] allegedly replied: 'Who's the third?

A theory is more impressive the greater the simplicity of its premises, the more different are the kinds of things it relates, and the more extended its range of applicability.

When you are courting a nice girl, an hour seems like a second. When you sit on a red-hot cinder, a second seems like an hour. That’s relativity. —Albert Einstein

One of the brighter humans, a German-born theoretical physicist called Albert Einstein, explained relativity to dimmer members of his species by telling them, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute.” What if looking at the pretty girl felt like putting your hand on a hot stove? What was that? Quantum mechanics?

A large part of our attitude toward things is conditioned by opinions and emotions which we unconsciously absorb as children from our environment. In other words, it is tradition—besides inherited aptitudes and qualities—which makes us what we are. We but rarely reflect how relatively small as compared with the powerfu... See more

Einstein has a feeling for the central order of things. He can detect it in the simplicity of natural laws. We may take it that he felt this simplicity very strongly and directly during his discovery of the theory of relativity. Admittedly, this is a far cry from the contents of religion. I don't believe Einstein is tied to any religious tradition, and I rather think the idea of a personal God is entirely foreign to him.

Albert Einstein once said, “Sit with a beautiful woman for an hour and it seems like a minute, sit on a hot stove for a minute and it seems like an hour—that’s relativity.

Silence is the hardest scream

The total number of people who understand relativistic time, even after eighty years since the advent of special relativity, is still much smaller than the number of people who believe in horoscopes.

of the actual objects of physical reality. Physical objects are not in space, but these objects are spatially extended.

it is not difficult to understand why the general principle of relativity (on the basis of the equivalence principle) has led to a theory of gravitation.

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.

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.

More careful reflection teaches us, however, that the special theory of relativity does not compel us to deny ether...To deny the ether is ultimately to assume that empty space has no physical qualities whatever.

result: every description of events in space involves the use of a rigid body to which such events have to be referred. The resulting relationship takes for granted that the laws of Euclidean geometry hold for ‘distances’, the ‘distance’ being represented physically by means of the convention of two marks on a rigid body.

The time—which, looking back, seems so idyllic—is gone forever when individuals or relatively small groups could be completely self-sufficient. It is only a slight exaggeration to say that mankind constitutes even now a planetary community of production and consumption.

Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory.

if, relative to K, K’ is a uniformly moving co-ordinate system devoid of rotation, then natural phenomena run their course with respect to K’ according to exactly the same general laws as with respect to K. This statement is called the Principle of Relativity (in the restricted sense).

The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as the elementary quantum of action is to the Quantum Theory: it is its absolute core.

Kada sedite sat vremena kraj lepe devojke, to prodje kao minut. Sedite minut na vrelu pec i to ce trajati kao sat. To se zove relativitet.

The first half of the twentieth century, beginning with Albert Einstein’s 1905 papers on relativity and quantum theory, featured a revolution driven by physics.

Einstein, my upset stomach hates your theory [of General Relativity]—it almost hates you yourself! How am I to' provide for my students? What am I to answer to the philosophers?!!

The struggle, so violent in the early days of science, between the views of Ptolemy and Copernicus would then be quite meaningless. Either CS [coordinate system] could be used with equal justification. The two sentences, “the Sun is at rest and the Earth moves,” or “the Sun moves and the Earth is at rest,” would simply mean two different conventions concerning two different CS.

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.

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

The purpose of mechanics is to describe how bodies change their position in space with ‘time’.

I fucking hate special relativity

How did it come to pass that I was the one to develop the theory of relativity? The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought of as a child. But my intellectual development was retarded, as a result of which I began to wonder about space and time only when I had already grown up. Naturally I could go deeper into the problem than a child with normal abilities.

I sometimes ask myself how it came about that I was the one to develop the theory of relativity. The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought of as a child. But my intellectual development was retarded, as a result of which I began to wonder about space and time only when I had already grown up.

I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according to well understood logical rules, step by step, a stately edifice, while his imaginative power brings out clearly the hidden relations between its parts. A well constructed theory is in some respects undoubtedly an artistic production. A fine example is the famous Kinetic Theory of Maxwell. ... The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art.

I had a sneaking suspicion that time was not constant, but I guess I could never prove it. I suppose it didn’t really matter. I even had a theory that time didn’t go in straight line at all. I knew I was no Albert Einstein, but I had the sneaking suspicion that everything had happened, was happening, or would happen was really happening all the time. There was no past, present, and future. Everything was going on all at once and forever. If that was true, then each moment was eternity.

During the youthful period of mankind's spiritual evolution human fantasy created gods in man's own image, who, by the operations of their will were supposed to determine, or at any rate to influence, the phenomenal world. Man sought to alter the disposition of these gods in his own favor by means of magic and prayer. The idea of God in the religions taught at present is a sublimation of that old concept of the gods. Its anthropomorphic character is shown, for instance, by the fact that men appeal to the Divine Being in prayers and plead for the fulfillment of their wishes. Nobody, certainly, will deny that the idea of the existence of an omnipotent, just, and omnibeneficent personal God is able to accord man solace, help, and guidance; also, by virtue of its simplicity it is accessible to the most undeveloped mind. But, on the other hand, there are decisive weaknesses attached to this idea in itself, which have been painfully felt since the beginning of history. That is, if this being is omnipotent, then every occurrence, including every human action, every human thought, and every human feeling and aspiration is also His work; how is it possible to think of holding men responsible for their deeds and thoughts before such an almighty Being? In giving out punishment and rewards He would to a certain extent be passing judgment on Himself. How can this be combined with the goodness and righteousness ascribed to Him? (Albert Einstein, Science, Philosophy, and Religion, A 1934 Symposium published by the Conference on Science, Philosophy and Religion in Their Relation to the Democratic Way of Life, Inc., New York, 1941; from Einstein's Out of My Later Years, Westport, Connecticut: Greenwood Press, 1970, pp. 26-27.)

For while religion prescribes brotherly love in the relations among the individuals and groups, the actual spectacle more resembles a battlefield than an orchestra. Everywhere, in economic as well as in political life, the guiding principle is one of ruthless striving for success at the expense of one's fellow. men. This competitive spirit prevails even in school and, destroying all feelings of human fraternity and cooperation, conceives of achievement not as derived from the love for productive and thoughtful work, but as springing from personal ambition and fear of rejection.

The owner of the means of production is in a position to purchase the labor power of the worker. By using the means of production, the worker produces new goods which become the property of the capitalist. The essential point about this process is the relation between what the worker produces and what he is paid, both measured in terms of real value. Insofar as the labor contract is "free," what the worker receives is determined not by the real value of the goods he produces, but by his minimum needs and by the capitalists' requirements for labor power in relation to the number of workers competing for jobs. It is important to understand that even in theory the payment of the worker is not determined by the value of his product.

I have known a great many intelligent people in my life. I knew Max Planck, Max von Laue, and Wemer Heisenberg. Paul Dirac was my brother-in-Iaw; Leo Szilard and Edward Teller have been among my closest friends; and Albert Einstein was a good friend, too. And I have known many of the brightest younger scientists. But none of them had a mind as quick and acute as Jancsi von Neumann. I have often remarked this in the presence of those men, and no one ever disputed me. [...] But Einstein's understanding was deeper than even Jancsi von Neumann's. His mind was both more penetrating and more original than von Neumann's. And that is a very remarkable statement. Einstein took an extraordinary pleasure in invention. Two of his greatest inventions are the Special and General Theories of Relativity; and for all of Jancsi's brilliance, he never produced anything so original.

If you could buckle your Bugs Bunny wristwatch to a ray of light, your watch would continue ticking but the hands wouldn't move. That's because at the speed of light there is no time. Time is relative to velocity. At high speeds, time is literally stretched. Since light is the ultimate in velocity, at light-speed time is stretched to its absolute and becomes static. Albert Einstein figured that one out.

However we select from nature a complex (of phenomena) using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate...But I do not doubt that the day will come when that description (the general theory of relativity), too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that that this process of deepening the theory has no limits.

Einstein, twenty-six years old, only three years away from crude privation, still a patent examiner, published in the Annalen der Physik in 1905 five papers on entirely different subjects. Three of them were among the greatest in the history of physics. One, very simple, gave the quantum explanation of the photoelectric effect—it was this work for which, sixteen years later, he was awarded the Nobel prize. Another dealt with the phenomenon of Brownian motion, the apparently erratic movement of tiny particles suspended in a liquid: Einstein showed that these movements satisfied a clear statistical law. This was like a conjuring trick, easy when explained: before it, decent scientists could still doubt the concrete existence of atoms and molecules: this paper was as near to a direct proof of their concreteness as a theoretician could give. The third paper was the special theory of relativity, which quietly amalgamated space, time, and matter into one fundamental unity. This last paper contains no references and quotes to authority. All of them are written in a style unlike any other theoretical physicist's. They contain very little mathematics. There is a good deal of verbal commentary. The conclusions, the bizarre conclusions, emerge as though with the greatest of ease: the reasoning is unbreakable. It looks as though he had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done.

In gravitational fields there are no such thing as rigid bodies with Euclidean properties; thus the fictitious rigid body of reference is of no avail in the general theory of relativity. ... For this reason non-rigid reference-bodies are used, which are, as a whole, not only moving in any way whatsoever, but which also suffer alterations in form ad lib. during their motion... This non-rigid reference-body, ... might appropriately be termed a "reference mollusc,"...

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.

Let us imagine ourselves transferred to our old friend, the railway carriage, which is travelling at a uniform rate. As long as it is moving uniformly, the occupant of the carriage is not sensible of its motion, and it is for this reason that he can without reluctance interpret the facts of the case as indicating that the carriage is at rest, but the embankment in motion. Moreover, according to the special principle of relativity, this interpretation is quite justified also from a physical point of view.

We thus obtain the following result: every description of events in space involves the use of a rigid body to which such events have to be referred. The resulting relationship takes for granted that the laws of Euclidean geometry hold for ‘distances’, the ‘distance’ being represented physically by means of the convention of two marks on a rigid body.

Professor Smith has kindly submitted his book to me before publication. After reading it thoroughly and with intense interest I am glad to comply with his request to give him my impression. The work is a broadly conceived attempt to portray man's fear-induced animistic and mythic ideas with all their far-flung transformations and interrelations. It relates the impact of these phantasmagorias on human destiny and the causal relationships by which they have become crystallized into organized religion. This is a biologist speaking, whose scientific training has disciplined him in a grim objectivity rarely found in the pure historian. This objectivity has not, however, hindered him from emphasizing the boundless suffering which, in its end results, this mythic thought has brought upon man. Professor Smith envisages as a redeeming force, training in objective observation of all that is available for immediate perception and in the interpretation of facts without preconceived ideas. In his view, only if every individual strives for truth can humanity attain a happier future; the atavisms in each of us that stand in the way of a friendlier destiny can only thus be rendered ineffective. His historical picture closes with the end of the nineteenth century, and with good reason. By that time it seemed that the influence of these mythic, authoritatively anchored forces which can be denoted as religious, had been reduced to a tolerable level in spite of all the persisting inertia and hypocrisy. Even then, a new branch of mythic thought had already grown strong, one not religious in nature but no less perilous to mankind -- exaggerated nationalism. Half a century has shown that this new adversary is so strong that it places in question man's very survival. It is too early for the present-day historian to write about this problem, but it is to be hoped that one will survive who can undertake the task at a later date.

Physicists had only recently discovered radioactivity,

Le Verrier left the solar system larger than he found it - one both better and less completely understood.

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.

All days are today. That is the relative paradox of the universe.

When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute—it’s longer than an hour. That’s relativity! Albert Einstein

light was both a wave and a particle.

To quote Albert Einstein,' said Sherman, "You stink and so do your relatives." "Einstein never said that," argued Garfield. "Did too," Insisted Sherman. "It's in his theory of relativity.

The enterprise of making sense of the material world turns on a key question: what happens when something observed in nature doesn’t fit within the established framework of existing human knowledge?

An observer who is sitting eccentrically on the disc K' is sensible of a force which acts outwards in a radial direction, and which would be interpreted as an effect of inertia (centrifugal force) by an observer who was at rest with respect to the original reference-body K. But the observer on the disc may regard his disc as a reference body which is “at rest”; on the basis of the general principle of relativity he is justified in doing this. The force acting on himself, and in fact on all other bodies which are at rest relative to the disc, he regards as the effect of a gravitational field.

As Vulcan’s troublesome history reveals, no one gives up on a powerful, or a beautiful, or perhaps simply a familiar and useful conception of the world without utter compulsion – and a real alternative.

People spoke to foreigners with an averted gaze, and everybody seemed to know somebody who had just vanished. The rumors of what had happened to them were fantastic and bizarre though, as it turned out, they were only an understatement of the real thing. Before going to see General Videla […], I went to […] check in with Los Madres: the black-draped mothers who paraded, every week, with pictures of their missing loved ones in the Plaza Mayo. (‘Todo mi familia!’ as one elderly lady kept telling me imploringly, as she flourished their photographs. ‘Todo mi familia!’) From these and from other relatives and friends I got a line of questioning to put to the general. I would be told by him, they forewarned me, that people ‘disappeared’ all the time, either because of traffic accidents and family quarrels or, in the dire civil-war circumstances of Argentina, because of the wish to drop out of a gang and the need to avoid one’s former associates. But this was a cover story. Most of those who disappeared were openly taken away in the unmarked Ford Falcon cars of the Buenos Aires military police. I should inquire of the general what precisely had happened to Claudia Inez Grumberg, a paraplegic who was unable to move on her own but who had last been seen in the hands of his ever-vigilant armed forces [….] I possess a picture of the encounter that still makes me want to spew: there stands the killer and torturer and rape-profiteer, as if to illustrate some seminar on the banality of evil. Bony-thin and mediocre in appearance, with a scrubby moustache, he looks for all the world like a cretin impersonating a toothbrush. I am gripping his hand in a much too unctuous manner and smiling as if genuinely delighted at the introduction. Aching to expunge this humiliation, I waited while he went almost pedantically through the predicted script, waving away the rumored but doubtless regrettable dematerializations that were said to be afflicting his fellow Argentines. And then I asked him about Senorita Grumberg. He replied that if what I had said was true, then I should remember that ‘terrorism is not just killing with a bomb, but activating ideas. Maybe that’s why she’s detained.’ I expressed astonishment at this reply and, evidently thinking that I hadn’t understood him the first time, Videla enlarged on the theme. ‘We consider it a great crime to work against the Western and Christian style of life: it is not just the bomber but the ideologist who is the danger.’ Behind him, I could see one or two of his brighter staff officers looking at me with stark hostility as they realized that the general—El Presidente—had made a mistake by speaking so candidly. […] In response to a follow-up question, Videla crassly denied—‘rotondamente’: ‘roundly’ denied—holding Jacobo Timerman ‘as either a journalist or a Jew.’ While we were having this surreal exchange, here is what Timerman was being told by his taunting tormentors: Argentina has three main enemies: Karl Marx, because he tried to destroy the Christian concept of society; Sigmund Freud, because he tried to destroy the Christian concept of the family; and Albert Einstein, because he tried to destroy the Christian concept of time and space. […] We later discovered what happened to the majority of those who had been held and tortured in the secret prisons of the regime. According to a Navy captain named Adolfo Scilingo, who published a book of confessions, these broken victims were often destroyed as ‘evidence’ by being flown out way over the wastes of the South Atlantic and flung from airplanes into the freezing water below. Imagine the fun element when there’s the surprise bonus of a Jewish female prisoner in a wheelchair to be disposed of… we slide open the door and get ready to roll her and then it’s one, two, three… go!

There are two foundational pillars upon which modern physics rests. One is Albert Einstein's general relativity, which provides a theoretical framework for understanding the universe on the largest of scales: stars, galaxies, clusters of galaxies, and beyond to the immense expanse of the universe itself. The other is quantum mechanics, which provides a theoretical framework for understanding the universe on the smallest of scales: molecules, atoms, and all the way down to subatomic particles like electrons and quarks. Through years of research, physicists have experimentally confirmed to almost unimaginable accuracy virtually all predictions made by each of these theories. But these same theoretical tools inexorably lead to another disturbing conclusion: As they are currently formulated, general relativity and quantum mechanics cannot both be right.

At rest, we know that its circumference is equal to p times the diameter. Once the merry-go-round is set into motion, however, the outer rim travels faster than the interior and hence, according to relativity, should shrink more than the interior, distorting the shape of the merry-go-round. This means that the circumference has shrunk and is now less than p times the diameter; that is, the surface is no longer flat. Space is curved.

PREFACE A New Look at the Legacy of Albert Einstein Genius. Absent-minded professor. The father of relativity. The mythical figure of Albert Einstein—hair flaming in the wind, sockless, wearing an oversized sweatshirt, puffing on his pipe, oblivious to his surroundings—is etched indelibly on our minds. “A pop icon on a par with Elvis Presley and Marilyn Monroe, he stares enigmatically from postcards, magazine covers, T-shirts, and larger-than-life posters. A Beverly Hills agent markets his image for television commercials. He would have hated it all,” writes biographer Denis Brian. Einstein is among the greatest scientists of all time, a towering figure who ranks alongside Isaac Newton for his contributions. Not surprisingly, Time magazine voted him the Person of the Century. Many historians have placed him among the hundred most influential people of the last thousand years.

... there’s a common trick nature plays on its would-be investigators: resemblance, the human urge to map the unknown onto the already known, can be a snare. Just because something looks like something else doesn’t mean that the backstory for both must be the same. Rocks scattered across the sky may appear to be a rubble field left behind by an explosion…but unless you stop to think how else you might get there, you rely on assumptions not in evidence.

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.

In a letter he wrote in 1953, Einstein related, “Every individual has to retain his way of thinking if he does not want to get lost in the maze of possibilities. However, nobody is sure of having taken the right road, me the least.”   By

The tendencies we have mentioned are something new for America. They arose when, under the influence of the two World Wars and the consequent concentration of all forces on a military goal, a predominantly military mentality developed, which with the almost sudden victory became even more accentuated. The characteristic feature of this mentality is that people place the importance of what Bertrand Russell so tellingly terms “naked power” far above all other factors which affect the relations between peoples. The Germans, misled by Bismarck’s successes in particular, underwent just such a transformation of their mentality—in consequence of which they were entirely ruined in less than a hundred years. I must frankly confess that the foreign policy of the United States since the termination of hostilities has reminded me, sometimes irresistibly, of the attitude of Germany under Kaiser Wilhelm II, and I know that, independent of me, this analogy has most painfully occurred to others as well. It is characteristic of the military mentality that non-human factors (atom bombs, strategic bases, weapons of all sorts, the possession of raw materials, etc.) are held essential, while the human being, his desires and thoughts—in short, the psychological factors—are considered as unimportant and secondary. Herein lies a certain resemblance to Marxism, at least insofar as its theoretical side alone is kept in view. The individual is degraded to a mere instrument; he becomes “human materiel.” The normal ends of human aspiration vanish with such a viewpoint. Instead, the military mentality raises “naked power” as a goal in itself—one of the strangest illusions to which men can succumb.

If I am full of confident hope concerning the progress of international organization in general, that feeling is based not so much on my confidence in the intelligence and high-mindedness of my fellows, but rather on the irresistible pressure of economic developments

The United States is the most powerful among the technically advanced countries in the world today. Its influence on the shaping of international relations is absolutely incalculable. But America is a large country and its people have so far not shown much interest in great international problems, among which the problem of disarmament occupies first place today. This must be changed, if only in America's own interest. The last war has shown that there are no longer any barriers between the continents and that the destinies of all countries are closely interwoven. The people of this country must realize that they have a great responsibility in the sphere of international politics. The part of passive spectator is unworthy of this country and is bound in the end to lead to disaster all round.

But now, in the daily business of our warped cosmos, Vulcan barley registers, even as an antiquarian curiosity. Only a few have some vague memory of the story – mostly physicists and astronomers with a historical bent. For them, Vulcan is a cautionary tale: it’s so damn easy to see what one wants or expects to find.

One is ordinarily accustomed to study geometry divorced from any relation between its concepts and experience... This is satisfactory to the pure mathematician. He is satisfied if he can deduce his theorems from axioms correctly, that is, without errors of logic. The question as to whether Euclidean geometry is true or not does not concern him... The physicist is concerned with the question as to whether the theorems of geometry are true or not. That Euclidean geometry, from this point of view, affirms something more than the mere deductions derived logically from definitions may be seen from the following simple consideration.

Finally, in 1905, he found the answer. His name was Albert Einstein, and his theory was called special relativity. He discovered that you cannot outrace a lightbeam, because the speed of light is the ultimate velocity in the universe. If you approach it, strange things happen. Your rocket becomes heavier, and time slows down inside it. If you were to somehow reach light speed, you would be infinitely heavy and time would stop. Both conditions are impossible, which means you cannot break the light barrier. Einstein became the cop on the block, setting the ultimate speed limit in the universe. This barrier has bedeviled generations of rocket scientists ever since.

By far the most important consequence of the conceptual revolution brought about in physics by relativity and quantum theory lies not in such details as that meter sticks shorten when they move or that simultaneous position and momentum have no meaning, but in the insight that we had not been using our minds properly and that it is important to find out how to do so.

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)

Lederman is also a charismatic personality, famous among his colleagues for his humor and storytelling ability. One of his favorite anecdotes relates the time when, as a graduate student, he arranged to bump into Albert Einstein while walking the grounds at the Institute for Advanced Study at Princeton. The great man listened patiently as the eager youngster explained the particle-physics research he was doing at Columbia, and then said with a smile, “That is not interesting.

A good question is like the one Albert Einstein asked himself as a small boy—“What would you see if you were traveling on a beam of light?” That question launched the theory of relativity, E=MC2, and the atomic age. A good question is not concerned with a correct answer. A good question cannot be answered immediately. A good question challenges existing answers. A good question is one you badly want answered once you hear it, but had no inkling you cared before it was asked. A good question creates new territory of thinking. A good question reframes its own answers. A good question is the seed of innovation in science, technology, art, politics, and business. A good question is a probe, a what-if scenario. A good question skirts on the edge of what is known and not known, neither silly nor obvious. A good question cannot be predicted. A good question will be the sign of an educated mind. A good question is one that generates many other good questions. A good question may be the last job a machine will learn to do. A good question is what humans are for.

Since her death in 1979, the woman who discovered what the universe is made of has not so much as received a memorial plaque. Her newspaper obituaries do not mention her greatest discovery. […] Every high school student knows that Isaac Newton discovered gravity, that Charles Darwin discovered evolution, and that Albert Einstein discovered the relativity of time. But when it comes to the composition of our universe, the textbooks simply say that the most abundant atom in the universe is hydrogen. And no one ever wonders how we know.

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.

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.

This Saturday, Galle and a volunteer assistant, Heinrich Ludwig d’Arrest, command the main telescope. Galle stands at the eyepiece and guides the instrument, pointing toward Capricorn. As each star comes into view, he calls out its brightness and position. D’Arrest pores over a sky map, ticking off each candidate as it reveals itself as a familiar object. So it goes until, sometime between midnight and 1 A.M., Galle reels out the numbers for one more mote of light invisible to the naked eye: right ascension 21 h, 53 min, 25.84 seconds. D’Arrest glances down at the chart, then yelps: “that star is not on the map!” The younger man runs to fetch the observatory’s director, who earlier that day had only reluctantly given his permission to attempt what he seems to have thought a fool’s errand. Together, the trio continue to watch the new object until it sets at around 2:30 in the morning. True stars remain mere points in even the most powerful telescopes. This does not, showing instead an unmistakable disk, a full 3.2 arcseconds across—just as Le Verrier had told them to expect. That visible circle can mean just one thing: Galle has just become the first man to see what he knows to be a previously undiscovered planet, one that would come to be called Neptune, just about exactly where Urbain-Jean-Joseph Le Verrier told him to look. —

Vulcan is long gone, almost completely forgotten. It may seem today to be merely a curiosity, just another mistake our ancestors made, about which we now know better. But the issue of what to do with failure in science was tricky right at the start of the Scientific Revolution, and it remains so now. We may—we do—know more than the folks back then. But we are not thus somehow immune to the habits of mind, the leaps of imagination, or the capacity for error that they possessed. Vulcan’s biography is one of the human capacity to both discover and self-deceive. It offers a glimpse of how hard it is to make sense of the natural world, and how difficult it is for any of us to unlearn the things we think are so, but aren’t.

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.

Finally, the greatest scientist of the twentieth century, Albert Einstein (1879-1955) was a pantheist. Of course Einstein is best known for his theory of relativity, but he frequently pronounced on political and ethical questions. Einstein made it plain that he did not believe in any kind of personal humanlike God who would work miracles and answer prayers in defiance of the laws of nature, and reward and punish us in the afterlife. For Einstein God was the order and harmony and law of the universe itself, and science was in that sense a religious quest. "I have never imputed to Nature a purpose or goal, or anything that could be understood as anthropomorphic. What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility. This is a genuinely religious feeling that has nothing to do with mysticism.

Man is, at one and the same time, a solitary being and a social being. As a solitary being, he attempts to protect his own existence and that of those who are closest to him, to satisfy his personal desires, and to develop his innate abilities. As a social being, he seeks to gain the recognition and affection of his fellow human beings, to share in their pleasures, to comfort them in their sorrows, and to improve their conditions of life. Only the existence of these varied, frequently conflicting, strivings accounts for the special character of a man, and their specific combination determines the extent to which an individual can achieve an inner equilibrium and can contribute to the well-being of society. It is quite possible that the relative strength of these two drives is, in the main, fixed by inheritance. But the personality that finally emerges is largely formed by the environment in which a man happens to find himself during his development, by the structure of the society in which he grows up, by the tradition of that society, and by its appraisal of particular types of behavior. The abstract concept “society” means to the individual human being the sum total of his direct and indirect relations to his contemporaries and to all the people of earlier generations. The individual is able to think, feel, strive, and work by himself; but he depends so much upon society—in his physical, intellectual, and emotional existence—that it is impossible to think of him, or to understand him, outside the framework of society. It is “society” which provides man with food, clothing, a home, the tools of work, language, the forms of thought, and most of the content of thought; his life is made possible through the labor and the accomplishments of the many millions past and present who are all hidden behind the small word “society.

What matters is not how much we remember, but how we remember. As I see it, intelligence is closely related to creativity, to noticing something new, to making unexpected connections between disparate facts. Isaac Newton’s genius consisted of realizing that what makes an apple fall from a tree is the same force that keeps the moon in its orbit around the earth: gravity. Centuries later, in his general theory of relativity, Albert Einstein uncovered another astounding relationship when he noted that the effect of the force of gravity is indistinguishable from the acceleration of a spaceship in outer space or the tug we feel in an elevator when it starts to move. Attempting to memorize facts by rote does nothing more than distract our attention from what really matters, the deeper understanding required to establish meaning and notice connections—that which constitutes the basis of intelligence. The method of loci does nothing to help us understand the things we memorize; it is just a formula for memorization that, in fact, competes against comprehension. As we saw in the previous chapter, Shereshevskii was able to memorize a list effortlessly using the method of loci, but was incapable of grasping its content enough to pick out the liquids from the list or, on another occasion, to realize that he had memorized a sequence of consecutive numbers. Using the method of loci to store these lists left Shereshevskii no room to make any of the categorizations that we perform unconsciously (person, animal, liquid, etc.) or to find basic patterns in a list of numbers. To be creative and intelligent, we must go beyond merely remembering and undertake completely different processes: we must assimilate concepts and derive meaning. Focusing on memorization techniques limits our ability to understand, classify, contextualize, and associate. Like memorization, these processes also help to secure memories, but in a more useful and elaborate way; these are precisely the processes that should be developed and encouraged by the educational system.

Today, the relativity of time is a proven scientific fact. This was revealed by Einstein's theory of relativity during the early part of the 20th century. Until then, it was not known that time was relative, nor that it could change according to the circumstances. Yet, the renowned scientist Albert Einstein proved this fact by discovering the theory of relativity. He showed that time is dependent on mass and velocity. However, the Qur'an had already included information about time's being relative! Some verses about the subject read: … A day with your Lord is equivalent to a thousand years in the way you count. (Qur'an, 22:47) He directs the whole affair from heaven to Earth. Then it will again ascend to Him on a day whose length is a thousand years by the way you measure. (Qur'an, 32:5) The angels and the spirit ascend to Him in a day whose length is fifty thousand years. (Qur'an, 70:4) The fact that the relativity of time is so definitely mentioned in the Qur'an, which began to be revealed in 610, is more evidence that it is a divine book.

A good question is like the one Albert Einstein asked himself as a small boy—“What would you see if you were traveling on a beam of light?” That question launched the theory of relativity, E=MC2, and the atomic age.

On his journey home from delivering his acceptance speech in Sweden the following summer, Einstein stopped in Copenhagen to see Bohr, who met him at the train station to take him home by streetcar. On the ride, they got into a debate. “We took the streetcar and talked so animatedly that we went much too far,” Bohr recalled. “We got off and traveled back, but again rode too far.” Neither seemed to mind, for the conversation was so engrossing. “We rode to and fro,” according to Bohr, “and I can well imagine what the people thought about us.”43 More than just a friendship, their relationship became an intellectual entanglement that began with divergent views about quantum mechanics but then expanded into related issues of science, knowledge, and philosophy. “In all the history of human thought, there is no greater dialogue than that which took place over the years between Niels Bohr and Albert Einstein about the meaning of the quantum,” says the physicist John Wheeler, who studied under Bohr. The social philosopher C. P. Snow went further. “No more profound intellectual debate has ever been conducted,” he proclaimed.44 Their dispute went to the fundamental heart of the design of the cosmos: Was there an objective reality that existed whether or not we could ever observe it? Were there laws that restored strict causality to phenomena that seemed inherently random? Was everything in the universe predetermined?

As it was, Einstein merely had the pleasure of renouncing the cosmological constant, which he had never liked.53 In a new edition of his popular book on relativity published in 1931, he added an appendix explaining why the term he had pasted into his field equations was, thankfully, no longer necessary.54 “When I was discussing cosmological problems with Einstein,” George Gamow later recalled, “he remarked that the introduction of the cosmological term was the biggest blunder he ever made in his life.”55 In fact, Einstein’s blunders were more fascinating and complex than even the triumphs of lesser scientists. It was hard simply to banish the term from the field equations. “Unfortunately,” says Nobel laureate Steven Weinberg, “it was not so easy just to drop the cosmological constant, because anything that contributes to the energy density of the vacuum acts just like a cosmological constant.”56 It turns out that the cosmological constant not only was difficult to banish but is still needed by cosmologists, who use it today to explain the accelerating expansion of the universe.57 The mysterious dark energy that seems to cause this expansion behaves as if it were a manifestation of Einstein’s constant. As a result, two or three times each year fresh observations produce reports that lead with sentences along the lines of this one from November 2005: “The genius of Albert Einstein, who added a ‘cosmological constant’ to his equation for the expansion of the universe but then retracted it, may be vindicated by new research.

In learning general relativity, and then in teaching it to classes at Berkeley and MIT, I became dissatisfied with what seemed to be the usual approach to the subject. I found that in most textbooks geometric ideas were given a starring role, so that a student...would come away with an impression that this had something to do with the fact that space-time is a Riemannian [curved] manifold. Of course, this was Einstein's point of view, and his preeminent genius necessarily shapes our understanding of the theory he created. However, I believe that the geometrical approach has driven a wedge between general relativity and [Quantum Field Theory]. As long as it could be hoped, as Einstein did hope, that matter would eventually be understood in geometrical terms, it made sense to give Riemannian geometry a primary role in describing the theory of gravitation. But now the passage of time has taught us not to expect that the strong, weak, and electromagnetic interactions can be understood in geometrical terms, and too great an emphasis on geometry can only obscuret he deep connections between gravitation and the rest of physics...[My] book sets out the theory of gravitation according to what I think is its inner logic as a branch of physics, and not according to its historical development. It is certainly a historical fact that when Albert Einstein was working out general relativity, there was at hand a preexisting mathematical formalism, that of Riemannian geometry, that he could and did take over whole. However, this historical fact does not mean that the essence of general relativity necessarily consists in the application of Riemannian geometry to physical space and time. In my view, it is much more useful to regard general relativity above all as a theory of gravitation, whose connection with geometry arises from the peculiar empirical properties of gravitation.

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.
