Nuclear Physics Quotes

I think the writing of literature should give pleasure. What else should it be about? It is not nuclear physics. It actually has to give pleasure or it is worth nothing.

Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

Every sentence I utter must be understood not as an affirmation, but as a question. [A caution he gives his students, to be wary of dogmatism.]

Is this nuclear physics or are you ordering a cake? It's a cake. You eat it,,you don't frame it.

John,” I said, “when you get older, you’re going to understand a lot of things you don’t understand now.” “You must mean nuclear physics,” he said. “I can hardly wait.

It was quite the most incredible event that has ever happened to me in my life. It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you. [Recalling in 1936 the discovery of the nucleus in 1909, when some alpha particles were observed instead of travelling through a very thin gold foil were seen to rebound backward, as if striking something much more massive than the particles themselves. He won the Nobel Prize in Chemistry for this discovery.]

That's the trouble with cookbooks. Like sex education and nuclear physics, they are founded on an illusion. They bespeak order, but they end in tears.

We were told that we had to win. Against whom? The atom? Physics? The universe? Victory is not an event for us, but a process.

Living with the belief that you’re a walking piece of shit is hell. The smarter the person is, the more hellish it is. The only way out of this hell is physical death. In any case, it seems so to many people. This is the real reason for the nuclear war that destroyed our civilization.

in the heat of unprecedented technological breakthroughs it is easy to think that we are invincible, like gods who would rule the world. But none of us need be reminded that the future of our planet is being held hostage by our own cleverness, with nuclear physics, chemistry, agribusiness, mineral exploration, and bioengineering threatening our biosphere in ways we could never have imagined even twenty years ago.

Let me tell you as a brain scientist and a computer engineering dropout - transhumanism is to brain computer interface, what nuclear weapons are to nuclear physics.

We’re cognizant, curious beings, capable of philosophical thought, nuclear physics, repeating Nerf weapons, global consciousness, Glade air fresheners, and sentient automobiles. But we’re assholes first.

I find it consistently difficult to get around the notion that we are all, in our very natures, assholes. I am an asshole. I’m afraid you are also. That’s why the conversation about good manners even exists in the first place. We’re cognizant, curious beings, capable of philosophical thought, nuclear physics, repeating Nerf weapons, global consciousness, Glade air fresheners, and sentient automobiles. But we’re assholes first.

As chemists, we must rename [our] scheme and insert the symbols Ba, La, Ce in place of Ra, Ac, Th. As nuclear chemists closely associated with physics, we cannot yet convince ourselves to make this leap, which contradicts all previous experience in nuclear physics.

A few years after I gave some lectures for the freshmen at Caltech (which were published as the Feynman Lectures on Physics), I received a long letter from a feminist group. I was accused of being anti-women because of two stories: the first was a discussion of the subtleties of velocity, and involved a woman driver being stopped by a cop. There's a discussion about how fast she was going, and I had her raise valid objections to the cop's definitions of velocity. The letter said I was making the women look stupid. The other story they objected to was told by the great astronomer Arthur Eddington, who had just figured out that the stars get their power from burning hydrogen in a nuclear reaction producing helium. He recounted how, on the night after his discovery, he was sitting on a bench with his girlfriend. She said, "Look how pretty the stars shine!" To which he replied, "Yes, and right now, I'm the only man in the world who knows how they shine." He was describing a kind of wonderful loneliness you have when you make a discovery. The letter claimed that I was saying a women is incapable of understanding nuclear reactions. I figured there was no point in trying to answer their accusations in detail, so I wrote a short letter back to them: "Don't bug me, Man!

What I remember most is that the laws of physics no longer seemed to apply. Gravity was backwards and the world was, I'm quite certain, moving in slow motion. His pull wasn't a pull; I was just falling upward, and he caught me. There really was no beginning or end to the kiss; it wasn't even really there- and because of that, it was tremendous. Our lips were just four sweet, shy people meeting, saying, "Hello, it's nice to meet you." But what passed between them was massive. Nuclear. And in an instant, every cobweb inside me was obliterated. My inner struggles, my uncertainty, my fear of tiger attack... gone. Just the feeling of being a newborn, a pure soul just waiting to be imprinted upon.

I am an atheist.

Presidents and generals may not understand nuclear physics, but they have a good grasp of what nuclear bombs can do.

the statement “All uranium-235 spheres are less than a mile in diameter” could be thought of as a law of nature because, according to what we know about nuclear physics, once a sphere of uranium-235 grew to a diameter greater than about six inches, it would demolish itself in a nuclear explosion. Hence we can be sure that such spheres do not exist. (Nor would it be a good idea to try to make one!)

When the Soviet Union launched Sputnik in 1957, my parents, like the rest of America, were terrified. The Soviets had nuclear weapons and now were ahead of us in space. So my parents marched me and Owen into our living room, sat us down, and said, " You boys are going to study math and Science so we can beat the Soviets!" I thought that was a lot of pressure to put on a six-year old. But own and I were obedient sons, so we studied math and science. And we were good at it.. Owen was the first in our family to go to college. He went to MIT, graduating with a degree in physics, and then became a photographer. I went to Harvard, and became a comedian. My poor parents. But we still beat the Soviets. You're welcome.

(The string is extremely tiny, at the Planck length of 10 ^-33 cm, a billion billion times smaller than a proton, so all subatomic particles appear pointlike.) If we were to pluck this string, the vibration would change; the electron might turn into a neutrino. Pluck it again and it might turn into a quark. In fact, if you plucked it hard enough, it could turn into any of the known subatomic particles. Strings can interact by splitting and rejoining, thus creating the interactions we see among electrons and protons in atoms. In this way, through string theory, we can reproduce all the laws of atomic and nuclear physics. The "melodies" that can be written on strings correspond to the laws of chemistry. The universe can now be viewed as a vast symphony of strings.

The transition between our current Type 0 civilization and a future Type I civilization is perhaps the greatest transition in history. It will determine whether we will continue to thrive and flourish, or perish due to our own folly. This transition is extremely dangerous because we still have all the barbaric savagery that typified our painful rise from the swamp. Peel back the veneer of civilization, and we still see the forces of fundamentalism, sectarianism, racism, intolerance, etc., at work. Human nature has not changed much in the past 100,000 years, except now we have nuclear, chemical, and biological weapons to settle old scores.

Good science requires the interplay of analysis and synthesis. One never knows if basic research is truly basic until one knows what it is basic to. Modern physics came into its own not because of its theories—which can be enormously counterintuitive and highly controversial (muons, wavicles, superstrings, the anthropic principle, and all that)—but because physicists built the atomic bomb and modern nuclear power plants.

Sigmund Freud, he said, was the one who had introduced the single great idea upon which all the significant developments of the twentieth century had rested: the invisible is more important than the visible. You would never have had Einstein if Freud hadn't convinced the world of this first. You would never have had nuclear physics.

Nuclear didn't describe families. How could it? Dry physics was not equal to that task. In the twentieth century we needed a biological metaphor, Darwinian in scope, to suggest the gnash and crash of carnivorous life in the family gene pool. But for the 21st century, the new century, I think the metaphors must be chemical. Molecular. In the molecular family people are connected without being bound. They spindle themselves around shared experiences and affections rather than splashing in the shared gene pool.

Jeth had an unnatural talent for nuclear physics. Should that be a crime? He didn't like governments. Who did? How smart do you have to be before cynicism counts as villainy? And oh, God forbid you become independently wealthy enough to buy an island. Suddenly it's the Island of Dr. X, and the press can't refer to you without using the word "lair.

The Fukushima nuclear complex went on to become the worst man-made engineering disaster in all of human history, outside of war.

Wasting nuclear power on warheads is a barbaric use of a scientific revolution.

But eighteen seconds is a long time in neutron physics—and an eternity in a nuclear reactor with a high positive void coefficient.

The most striking impression was that of an overwhelming bright light. I had seen under similar conditions the explosion of a large amount—100 tons—of normal explosives in the April test, and I was flabbergasted by the new spectacle. We saw the whole sky flash with unbelievable brightness in spite of the very dark glasses we wore. Our eyes were accommodated to darkness, and thus even if the sudden light had been only normal daylight it would have appeared to us much brighter than usual, but we know from measurements that the flash of the bomb was many times brighter than the sun. In a fraction of a second, at our distance, one received enough light to produce a sunburn. I was near Fermi at the time of the explosion, but I do not remember what we said, if anything. I believe that for a moment I thought the explosion might set fire to the atmosphere and thus finish the earth, even though I knew that this was not possible.

The half-life of a substance is the time it takes for it to lose one half of its initial value. In nuclear physics, it’s the time it takes for unstable atoms to lose energy by emitting radiation. In biology, it usually refers to the time it takes to eliminate half of a substance (water, alcohol, pharmaceuticals) from the body. In chemistry, it is the time required to convert one half or a reactant (hydrogen or oxygen, for example) to product (water). In love, it’s the amount of time it takes for lovers to feel half of what they once did. When Natasha thinks about love, this is what she thinks: nothing lasts forever. Like hydrogen-7 or lithium-5 or boron-7, love has an infinitesimally small half-life that decays to nothing. And when it’s gone, it’s like it was never there at all.

In fact, there seem to be just four kinds of interaction between particles which, in the order of decreasing strength, are the nuclear force, electrical interactions, the beta-decay interaction, and gravity.

What gives modern society a superficial appearance of individualism, independence, and self-reliance is the vanishing of the ties that formerly linked individuals into small-scale communities. Today, nuclear families commonly have little connection to their next-door neighbors or even to their cousins. Most people have friends, but friends nowadays tend to use each other only for entertainment. They do not usually cooperate in economic or other serious, practical activities, nor do they offer each other much physical or economic security. If you become disabled, you don’t expect your friends to support you. You depend on insurance or on the welfare department.

How much the world lost that September is immeasurable. The complementarity of the bomb, its mingled promise and threat, would not be canceled by the decisions of heads of state; their frail authority extends not nearly so far. Nuclear fission and thermonuclear fusion are not acts of Parliament; they are levers embedded deeply in the physical world, discovered because it was possible to discover them, beyond the power of men to patent or to hoard.

Nonetheless, the appeal of Copenhagen makes some sense, seen in this light. Quantum physics drove much of the technological and scientific progress of the past ninety years: nuclear power, modern computers, the Internet. Quantum-driven medical imaging changed the face of health care; quantum imaging techniques at smaller scales have revolutionized biology and kicked off the entirely new field of molecular genetics. The list goes on. Make some kind of personal peace with Copenhagen, and contribute to this amazing revolution in science . . . or take quantum physics seriously, and come face-to-face with a problem that even Einstein couldn't solve. Shutting up never looked so good.

Let us fool ourselves no longer. At the very moment Western nations, threw off the ancient regime of absolute government, operating under a once-divine king, they were restoring this same system in a far more effective form in their technology, reintroducing coercions of a military character no less strict in the organization of a factory than in that of the new drilled, uniformed, and regimented army. During the transitional stages of the last two centuries, the ultimate tendency of this system might b e in doubt, for in many areas there were strong democratic reactions; but with the knitting together of a scientific ideology, itself liberated from theological restrictions or humanistic purposes, authoritarian technics found an instrument at hand that h as now given it absolute command of physical energies of cosmic dimensions. The inventors of nuclear bombs, space rockets, and computers are the pyramid builders of our own age: psychologically inflated by a similar myth of unqualified power, boasting through their science of their increasing omnipotence, if not omniscience, moved by obsessions and compulsions no less irrational than those of earlier absolute systems: particularly the notion that the system itself must be expanded, at whatever eventual co st to life. Through mechanization, automation, cybernetic direction, this authoritarian technics has at last successfully overcome its most serious weakness: its original dependence upon resistant, sometimes actively disobedient servomechanisms, still human enough to harbor purposes that do not always coincide with those of the system. Like the earliest form of authoritarian technics, this new technology is marvellously dynamic and productive: its power in every form tends to increase without limits, in quantities that defy assimilation and defeat control, whether we are thinking of the output of scientific knowledge or of industrial assembly lines. To maximize energy, speed, or automation, without reference to the complex conditions that sustain organic life, have become ends in themselves. As with the earliest forms of authoritarian technics, the weight of effort, if one is to judge by national budgets, is toward absolute instruments of destruction, designed for absolutely irrational purposes whose chief by-product would be the mutilation or extermination of the human race. Even Ashurbanipal and Genghis Khan performed their gory operations under normal human limits. The center of authority in this new system is no longer a visible personality, an all-powerful king: even in totalitarian dictatorships the center now lies in the system itself, invisible but omnipresent: all its human components, even the technical and managerial elite, even the sacred priesthood of science, who alone have access to the secret knowledge by means of which total control is now swiftly being effected, are themselves trapped by the very perfection of the organization they have invented. Like the Pharoahs of the Pyramid Age, these servants of the system identify its goods with their own kind of well-being: as with the divine king, their praise of the system is an act of self-worship; and again like the king, they are in the grip of an irrational compulsion to extend their means of control and expand the scope of their authority. In this new systems-centered collective, this Pentagon of power, there is no visible presence who issues commands: unlike job's God, the new deities cannot be confronted, still less defied. Under the pretext of saving labor, the ultimate end of this technics is to displace life, or rather, to transfer the attributes of life to the machine and the mechanical collective, allowing only so much of the organism to remain as may be controlled and manipulated.

If we conceive all the changes in the physical world as reducible to the motion of atoms, motions generated by means of the fixed nuclear forces of those atoms, the whole of the world could thus be known by means of the natural sciences.

I challenge you to destroy whatever roadblock is keeping you from moving forward. Destroy it with your physical body if you must, but first, destroy it with a power greater than a nuclear bomb—the power of your mind. Think it gone and it will go.

The complexities of national deficits, trade failures, budget gaps, negotiations to end the nuclear arms race, the crises of the Middle East, all these cannot be understood by giving the facts alone. The public needs appropriate historical background and clarification. People who are not taught much geography, history, economics, and physics simply cannot reach reasonable conclusions without help from specialists. This is not elitism, it is something far more important; it is called education.

quantum physics would open the door to a host of practical inventions that now define the digital age, including the modern personal computer, nuclear power, genetic engineering, and laser technology (from which we get such consumer products as the CD player

the philosopher John W. Carroll compared the statement “All gold spheres are less than a mile in diameter” to a statement like “All uranium-235 spheres are less than a mile in diameter.” Our observations of the world tell us that there are no gold spheres larger than a mile wide, and we can be pretty confident there never will be. Still, we have no reason to believe that there couldn’t be one, and so the statement is not considered a law. On the other hand, the statement “All uranium-235 spheres are less than a mile in diameter” could be thought of as a law of nature because, according to what we know about nuclear physics, once a sphere of uranium-235 grew to a diameter greater than about six inches, it would demolish itself in a nuclear explosion. Hence we can be sure that such spheres do not exist. (Nor would it be a good idea to try to make one!) This distinction matters because it illustrates that not all generalizations we observe can be thought of as laws of nature, and that most laws of nature exist as part of a larger, interconnected system of laws.

Transhumanism is terrorism, for it is the very antithesis of life. Wasting precious resources on a pompous, narcissistic and megalomaniacal dream of extending life through cold, mechanical means, instead of helping to improve genuine human condition, transhumanists act as modern day terrorists who desecrate the very spirit of life and liberty without ever being held accountable. Let me tell you as a brain scientist and a computer engineering dropout - transhumanism is to brain computer interface, what nuclear weapons are to nuclear physics.

What is personal death? Asking this question and pausing to look inward - isn't personal death a concept? Isn't there a thought-and-picture series going on in the brain? These scenes of personal ending take place solely in the imagination, and yet they trigger great mental ad physical distress - thinking of one's cherished attachments an their sudden, irreversible termination. Similarly, if there is 'pain when I let some of the beauty of life in' - isn't this pain the result of thinking, 'I won't be here any longer to enjoy this beauty?' Or, 'No one will be around and no beauty left to be enjoyed if there is total nuclear devastation.' Apart from the horrendous tragedy of human warfare - why is there this fear of 'me' not continuing? Is it because I don't realize that all my fear and trembling is for an image? Because I really believe that this image is myself? In the midst of this vast, unfathomable, ever-changing, dying, and renewing flow of life, the human brain is ceaselessly engaged in trying to fix for itself a state of permanency and certainty. Having the capacity to think and form pictures of ourselves, to remember them and become deeply attached to them, we take this world of pictures and ideas for real. We thoroughly believe in the reality of the picture story of our personal life. We are totally identified with it and want it to go on forever. The idea of "forever" is itself an invention of the human brain. Forever is a dream. Questioning beyond all thoughts, images, memories, and beliefs, questioning profoundly into the utter darkness of not-knowing, the realization may suddenly dawn that one is nothing at all - nothing - that all one has been holding on to are pictures and dreams. Being nothing is being everything. It is wholeness. Compassion. It is the ending of separation, fear, and sorrow. Is there pain when no one is there to hold on? There is beauty where there is no "me".

One of my friends compared me to Bruce Banner, due to my work with radiation and human health. So I looked up Bruce Banner and this is what I found: Banner, a physicist, is sarcastic and seemingly very self-assured when he first appears in Incredible Hulk #1, but is also emotionally withdrawn in most fashions...Banner is considered one of the greatest scientific minds on Earth, possessing "a mind so brilliant it cannot be measured on any known intelligence test." He holds expertise in biology, chemistry, engineering, physiology, and nuclear physics.

O. Hahn and F. Strassmann have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they demonstrated the production of nuclei of barium, lanthanum, strontium, yttrium, and, more recently, of xenon and caesium. It can be shown by simple considerations that this type of nuclear reaction may be described in an essentially classical way like the fission of a liquid drop, and that the fission products must fly apart with kinetic energies of the order of hundred million electron-volts each.

What courses are people excited about now? I asked a blonde senior in cap and gown. Nuclear physics, maybe? Modern art? Civilizations of Africa? Looking at me as if I were some prehistoric dinosaur, she said: "Girls don't get excited about things like that anymore. We don't want careers. Our parents expect us to go to college, everybody goes. You're a social outcast at home if you don't. But a girl who got serious about anything she studied, like wanting to go on and do research, would be peculiar, unfeminine. I guess everybody wants to graduate with a diamond ring on her finger, that's the important thing.

... picture of a hot early stage of the universe was first put forward by the scientist George Gamow in a famous paper written in 1948 with a student of his, Ralph Alpher. Gamow had quite a sense of humour - he persuaded the nuclear scientist Hans Bethe to add his name to the paper to make the list of authors 'Alpher, Bethe, Gamow'...

I think it is almost impossible that he [Prophet Muhammad (saas)] could have known about things like the common origin of the universe, because scientists have only found out within the last few years with very complicated and advanced technological methods that this is the case. Somebody who did not know something about nuclear physics 1400 years ago could not, I think, be in a position to find out from his own mind for instance that the earth and the heavens had the same origin, or many others of the questions that we have discussed here. (Alfred Kroner, Professor of the Department of Geosciences, University of Mainz, Germany. One of the world's most famous geologists)

True genius is the one of the heart, not of intellect. Because intellect-less heart, though exploited a lot, still does good, whereas heartless intellect, with or without the awareness of it, ends up only exploiting others. But here's the thing, even true genius of intellect is not without its fare sense of responsibility towards the society. It's only the genius of halfbaked intellect that has absolutely no sense of service towards society - the only sense they have towards society, is that of domination or control. That is why one of the guardians of nuclear physics, Albert Einstein though initially encouraged the US government in a letter, to develop a nuclear weapon of their own against the Nazi nuclear program, ended up being an outspoken activist of nuclear-disarmament, and called his letter to Roosevelt "one great mistake of life". That is why the mother of radioactivity, Marie Curie never made a dime out of her discovery of radium, because to her, even amidst obscurity, science was service, unlike most so-called scientists of the modern world. That is why the man who literally electrified the world with his invention of alternating current, Nikola Tesla embraced happily other people stealing his inventions, and died a poor man in his apartment. You see, it's easy to make billions out of other people's pioneering work, the sign of true genius is an uncorrupted sense of service.

Some search for the North Pole. Others seek to split the atom. They are both perilous journeys. When it comes to the former, it is up to the men and women involved to consider risking their lives. I throw up my hands and leave them to it. However, when it comes to the latter, these nuclear adventurers risk the future of mankind, and I, for one, fear for us all.

out as reconnaissance and sabotage actions. This was including the destruction of foreign command posts and communications systems for foreign nuclear guidance programs. And much like the U.S. Special Forces, the Spetsnaz underwent exhaustive psychological and physical training, eventually being left to operate autonomously for days or weeks at a time. As they were now.

We were members of a research group with a great interest in nuclear physics and totally devoted to this branch of science--and ironically we ourselves had become victims of th atom bomb which was the very core of the theory we were studying. Here we lay, helpless in a dugout! And yet it was a precious experience for us. Placed on the experimentation table, we could watch the whole process in a most intimate way. We could observe the changes that where taking place and that would take place in the future. Crushed with grief because of the defeat of Japan, filled with anger and resentment, we nevertheless felt rising within us a new drive and a new motivation in our search for truth. In this devastated atomic desert, fresh and vigorous scientific life began to flourish.

At the very least, such superconductors could reduce the waste found in high-voltage electrical cables, thereby reducing the cost of electricity. One of the reasons an electrical plant has to be so close to a city is because of losses in the transmission lines. That is why nuclear power plants are so close to cities, which poses a health hazard, and why wind power plants cannot be placed in areas with the maximum wind.

Love, that most banal of things, that most clichéd of religious motivations, had more power—Sol now knew—than did strong nuclear force or weak nuclear force or electromagnetism or gravity. Love was these other forces, Sol realized. The Void Which Binds, the subquantum impossibility that carried information from photon to photon, was nothing more or less than love. But could love—simple, banal love—explain the so-called anthropic principle which scientists had shaken their collective heads over for seven centuries and more—that almost infinite string of coincidences which had led to a universe that had just the proper number of dimensions, just the correct values on electron, just the precise rules for gravity, just the proper age to stars, just the right prebiologies to create just the perfect viruses to become just the proper DNAs—in short, a series of coincidences so absurd in their precision and correctness that they defied logic, defied understanding, and even defied religious interpretation. Love? For seven centuries the existence of Grand Unification Theories and hyperstring post-quantum physics and Core-given understanding of the universe as self-contained and boundless, without Big Bang singularities or corresponding endpoints, had pretty much eliminated any role of God—primitively anthropomorphic or sophisticatedly post-Einsteinian—even as a caretaker or pre-Creation former of rules. The modern universe, as machine and man had come to understand it, needed no Creator; in fact, allowed no Creator. Its rules allowed very little tinkering and no major revisions. It had not begun and would not end, beyond cycles of expansion and contraction as regular and self-regulated as the seasons on Old Earth. No room for love there.

absurd.” Quantum mechanics seems to study that which doesn’t exist—but nevertheless proves true. It works. In the decades to come, quantum physics would open the door to a host of practical inventions that now define the digital age, including the modern personal computer, nuclear power, genetic engineering, and laser technology (from which we get such consumer products as the CD player and the bar-code reader commonly used in supermarkets).

I know that my predictions and ideas are looked upon with horror by Parisian intellectuals, the same people who did not foresee the fall of Communism, who believe that the peaceful ‘assimilation’ of immigrants is possible, who expatiate all page long on abstruse questions, who drone out truisms on ‘democracy’ and pious asininities on the ‘republic’. I am not backing down, however: war is coming and announcing itself with unheard-of violence: war in the streets, civil war, widespread terrorist war, a generalised conflict with Islam and, very probably, nuclear conflicts. This will probably be the face of the first half of the Twenty-first century. And we have never been less prepared: invaded, devirilised, physically and morally disarmed, the prey of a culture of meaninglessness and masochistic culpability. Europeans have never in their history been as weak as at this very moment when the Great Threat appears on the horizon.

In the first lively second (a second that many cosmologists will devote careers to shaving into ever-finer wafers) is produced gravity and the other forces that govern physics. In less than a minute the universe is a million billion miles across and growing fast. There is a lot of heat now, ten billion degrees of it, enough to begin the nuclear reactions that create the lighter elements—principally hydrogen and helium, with a dash (about one atom in a hundred million) of lithium.

By extending our techniques—and if necessary our definitions—still further we can infer the time duration of still faster physical events. We can speak of the period of a nuclear vibration. We can speak of the lifetime of the newly discovered strange resonances (particles) mentioned in Chapter 2. Their complete life occupies a time span of only 10-24 second, approximately the time it would take light (which moves at the fastest known speed) to cross the nucleus of hydrogen (the smallest known object).

These fields, which govern the interaction of all subatomic particles, are now called Yang-Mills fields. However, the puzzle that has stumped physicists within this century is why the subatomic field equations look so vastly different from the field equations of Einstein-that is, why the nuclear force seems so different from gravity. Some of the greatest minds in physics have tackled this problem, only to fail. Perhaps the reason for their failure is that they were trapped by common sense. Confined to three or four dimensions, the field equations of the subatomic world and gravitation are difficult to unify. The advantage of the hyperspace theory is that the Yang-Mills field, Maxwell's field, and Einstein's field can all be placed comfortably within the hyperspace field. We see that these fields fit together precisely within the hyperspace field like pieces in a jig-saw puzzle. The other advantage of field theory is that it allows us to calculate the precise energies at which we can expect space and time to foem wormholes.

.... attempts to combine these two forces with the strong nuclear force into what is called a grand unified theory (GUT). This title is rather an exaggeration: the resultant theories are not all that grand, nor are they fully unified, as they do not include gravity. Nor are they really complete theories, because they contain a number of parameters whose values cannot be predicted from a theory but have to be chosen to fit in with experiment. Nevertheless, they may be a step toward a complete, fully unified theory.

One of the most impressive discoveries was the origin of the energy of the stars, that makes them continue to burn. One of the men who discovered this was out with his girl friend the night after he realized that nuclear reactions must be going on in the stars in order to make them shine. She said "Look at how pretty the stars shine!" He said "Yes, and right now I am the only man in the world who knows why they shine." She merely laughed at him. She was not impressed with being out with the only man who, at that moment, knew why stars shine. Well, it is sad to be alone, but that is the way it is in this world.

Nuclear power harnesses the same atomic reaction as a nuclear bomb, but is designed to ensure that it is physically incapable of causing a nuclear explosion, and instead controls the release of neutrons to generate the required heat. While a power station’s reactor contains barely-enriched uranium or plutonium fuel, dispersed over a large area and surrounded by control rods to restrain the reaction, a nuclear bomb is designed with the specific intention of causing this same reaction to occur instantaneously and with far greater intensity, by using explosives to force two hemispheres of 90%+ enriched uranium or plutonium together.

Over the last century, our physical description of the world has simplified quite a bit. As far as particles are concerned, there appear to be only two kinds, quarks and leptons. Quarks are the constituents of protons and neutrons and many particles we have discovered similar to them. The class of leptons encompasses all particles not made of quarks, including electrons and neutrinos. Altogether, the known world is explained by six kinds of quarks and six kinds of leptons, which interact with each other through the four forces (or interactions, as they are also known): gravity, electromagnetism, and the strong and weak nuclear forces.

Belief that the Earth is only several thousands years old carries a curious implication. The physical evidence for the Earth's age emerged from the same atomic discoveries that later gave the world nuclear weaponry and power plants. The scientific understanding of uranium isotopes that produce the date 4.5 billion years ago is the same understanding of uranium isotopes that led to the production and detonation of nuclear bombs. If scientists do not understand uranium decay well enough to date the Earth, there also cannot be, and can never have been, nuclear weaponry. Certainly a world and a history absent these weapons are desirable, but they are counter-factual.

Bush’s description of how basic research provides the seed corn for practical inventions became known as the “linear model of innovation.” Although subsequent waves of science historians sought to debunk the linear model for ignoring the complex interplay between theoretical research and practical applications, it had a popular appeal as well as an underlying truth. The war, Bush wrote, had made it “clear beyond all doubt” that basic science—discovering the fundamentals of nuclear physics, lasers, computer science, radar—“is absolutely essential to national security.” It was also, he added, crucial for America’s economic security. “New products and new processes do not appear full-grown. They are founded on new principles and new conceptions, which in turn are painstakingly developed by research in the purest realms of science. A nation which depends upon others for its new basic scientific knowledge will be slow in its industrial progress and weak in its competitive position in world trade.” By the end of his report, Bush had reached poetic heights in extolling the practical payoffs of basic scientific research: “Advances in science when put to practical use mean more jobs, higher wages, shorter hours, more abundant crops, more leisure for recreation, for study, for learning how to live without the deadening drudgery which has been the burden of the common man for past ages.”9 Based on this report, Congress established the National Science Foundation.

In the first lively second (a second that many cosmologists will devote careers to shaving into ever-finer wafers) is produced gravity and the other forces that govern physics. In less than a minute the universe is a million billion miles across and growing fast. There is a lot of heat now, ten billion degrees of it, enough to begin the nuclear reactions that create the lighter elements—principally hydrogen and helium, with a dash (about one atom in a hundred million) of lithium. In three minutes, 98 percent of all the matter there is or will ever be has been produced. We have a universe. It is a place of the most wondrous and gratifying possibility, and beautiful, too. And it was all done in about the time it takes to make a sandwich.

As the physicist Richard Feynman once observed, “[Quantum mechanics] describes nature as absurd from the point of view of common sense. And it fully agrees with experiment. So I hope you can accept nature as She is— absurd.” Quantum mechanics seems to study that which doesn’t exist—but nevertheless proves true. It works. In the decades to come, quantum physics would open the door to a host of practical inventions that now define the digital age, including the modern personal computer, nuclear power, genetic engineering, and laser technology (from which we get such consumer products as the CD player and the bar-code reader commonly used in supermarkets). If the youthful Oppenheimer loved quantum mechanics for the sheer beauty of its abstractions, it was nevertheless a theory that would soon spawn a revolution in how human beings relate to the world.

Heisenberg repeated his story about the German bomb program to anyone who would listen for the rest of his life. Goudsmit, who had access to the Farm Hall reports and had seen the pathetic remnants of the Nazi nuclear program firsthand, knew Heisenberg’s story was a fabrication. But, with the existence of the Farm Hall transcripts itself classified, Goudsmit could state only that Heisenberg was lying, without explaining how he knew. The first popular account of the Manhattan Project, Brighter Than a Thousand Suns, written by the Swiss journalist Robert Jungk in 1958, repeated Heisenberg’s story almost verbatim. So did The Virus House, the first book dedicated solely to the history of the German bomb program, which relied heavily on interviews from Heisenberg and his fellow former Farm Hall detainees. (The author, David Irving, was later revealed to be a Holocaust denier.)

In order to verify the conservation of energy, we must be careful that we have not put any in or taken any out. Second, the energy has a large number of different forms, and there is a formula for each one. These are: gravitational energy, kinetic energy, heat energy, elastic energy, electrical energy, chemical energy, radiant energy, nuclear energy, mass energy. If we total up the formulas for each of these contributions, it will not change except for energy going in and out. It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way. However, there are formulas for calculating some numerical quantity, and when we add it all together it gives "28"'—always the same number. It is an abstract thing in that it does not tell us the mechanism or the reasons for the various formulas.

At the beginning of the twentieth century we understood the workings of nature on the scales of classical physics that are good down to about a hundredth of a millimetre. The work on atomic physics in the first thirty years of the century took our understanding down to lengths of a millionth of a millimetre. Since then, research on nuclear and high-energy physics has taken us to length scales that are smaller by a further factor of a billion. It might seem that we could go on forever discovering structures on smaller and smaller length scales. However, there is a limit to this series as with a series of nested Russian dolls. Eventually one gets down to a smallest doll, which can’t be taken apart any more. In physics the smallest doll is called the Planck length and is a millimetre divided by a 100,000 billion billion billion. We are not about to build particle accelerators that can probe to distances that small.

When a perspective is integrated, it is accommodated by the intelligence of the body as a whole. The axis of that intelligence rests on the pelvic floor, informed by the world in ways that are utterly beyond the cause-and-effect logic of which our culture is so fond. In its function, the embodied center of being within us has many of the qualities of what physics has dubbed the quantum vacuum. As systems scientist Ervin Laszlo describes the quantum vacuum, it is the locus of a vast energy field that is neither classically electromagnetic nor gravitational, nor yet nuclear in nature. Instead, it is the originating source of the known electromagnetic, gravitational and nuclear forces and fields. It is the originating source of matter itself.197 The integrating genius of the pelvic intelligence is the quantum vacuum of the self: touched by the present, it receives into it all the perspectives of our living, and then rebirths them as the living sensitivities of the felt self, awakening it to the mutual awareness of reality. The

Over the next 300 years, the Afro-Asian giant swallowed up all the other worlds. It consumed the Mesoamerican World in 1521, when the Spanish conquered the Aztec Empire. It took its first bite out of the Oceanic World at the same time, during Ferdinand Magellan’s circumnavigation of the globe, and soon after that completed its conquest. The Andean World collapsed in 1532, when Spanish conquistadors crushed the Inca Empire. The first European landed on the Australian continent in 1606, and that pristine world came to an end when British colonisation began in earnest in 1788. Fifteen years later the Britons established their first settlement in Tasmania, thus bringing the last autonomous human world into the Afro-Asian sphere of influence. It took the Afro-Asian giant several centuries to digest all that it had swallowed, but the process was irreversible. Today almost all humans share the same geopolitical system (the entire planet is divided into internationally recognised states); the same economic system (capitalist market forces shape even the remotest corners of the globe); the same legal system (human rights and international law are valid everywhere, at least theoretically); and the same scientific system (experts in Iran, Israel, Australia and Argentina have exactly the same views about the structure of atoms or the treatment of tuberculosis). The single global culture is not homogeneous. Just as a single organic body contains many different kinds of organs and cells, so our single global culture contains many different types of lifestyles and people, from New York stockbrokers to Afghan shepherds. Yet they are all closely connected and they influence one another in myriad ways. They still argue and fight, but they argue using the same concepts and fight using the same weapons. A real ‘clash of civilisations’ is like the proverbial dialogue of the deaf. Nobody can grasp what the other is saying. Today when Iran and the United States rattle swords at one another, they both speak the language of nation states, capitalist economies, international rights and nuclear physics.

It is the nuclear "burning" of hydrogen which supplies the energy of the sun; the hydrogen is converted into helium. Furthermore, ultimately, the manufacture of various chemical elements proceeds in the centers of the stars, from hydrogen. The stuff of which we are made, was "cooked" once, in a star, and spit out. How do we know? Because there is a clue. The proportion of the different isotopes— how much C12 , how much C13 , etc., is something which is never changed by chemical reactions, because the chemical reactions are so much the same for the two. The proportions are purely the result of nuclear reactions. By looking at the proportions of the isotopes in the cold, dead ember which we are, we can discover what the furnace was like in which the stuff of which we are made was formed. That furnace was like the stars, and so it is very likely that our elements were "made" in the stars and spit out in the explosions which we call novae and super- novae. Astronomy is so close to physics that we shall study many astronomical things as we go along.

In this crucible of velocity, while feeling vulnerable and helpless to control your world of thoughts and images, you may discover a certain softness, an almost abstract tenderness toward everything and everyone. With that comes a moment of relief and of physical and mental relaxation. It is a feeling of sympathy and warmth toward everything outside of yourself along with the dropping away of an intensified self-consciousness. You are hardly alone in having had this experience. Almost universally, the one in the second state calls it Love or Compassion. Michaux called it "Misericordia in wave forms." But remember, you are still living in the great speed, and this too can "run wild." For a moment, sometimes a flashing moment, it brings you out beyond yourself, transcending your mental turmoil. It first stirred in you when you realized that you could be neutral; you could accommodate both intense pain and pleasure without attachment, without preference. You now may find that you are capable of experiencing wonderfully compassionate urges, and that this, more than anything else, is nuclear to your being. If ever there is an antidote to madness, it is here, in an opening out.

will give you anything I have—anything you want, if you let me go down on you right now.” I lie back, enjoy the fullness, and try to decide in the mush that is my brain. “I’ve never done it,” I whisper, and Jack must find the situation unacceptable, because he drops to his knees in front of me and inhales deeply against the crease of my abdomen. It takes exactly two swipes of his tongue to send me to outer space. One around my opening, where he’s stretching me too wide, and I think I’m going to die of embarrassment, of heat, of the liquid pressure that grows with each of his guttural groans. Then he moves up to my clit, and I know—I know—that nothing has ever felt like this in my life, that good things come sparingly, that I should try to make this last, but it’s over before it starts. My body seizes and snaps and bursts into a bubble of simple, pure, physical pleasure that feels too intense to weather alone. My fingers pull Jack’s hair too tight, dig in his scalp, and he keeps on eating at me, even when I’m coming down. His fingers stay deep inside, as if to give me something to contract around while I ride it out, and it’s perfect, this. It’s explosive, crashing, nuclear.

I don’t believe a word of the whole thing,” said Heisenberg upon hearing the news. “I don’t believe it has anything to do with uranium.” Hahn jeered, “If the Americans have a uranium bomb then you’re all second raters. Poor old Heisenberg.” After they heard the BBC report the news in great detail later that night, Heisenberg and the others accepted the truth: they had been beaten. Over the next few days, Heisenberg attempted to work out how his project had fallen so far behind; his fumbling calculations show that he had never really understood how to even build a bomb in the first place, though he had certainly thought he’d understood it. And the bickering of the other scientists at Farm Hall confirmed what documents captured by Alsos had already suggested: the Nazi bomb program, unlike the Manhattan Project, was a disorganized mess, with vital information compartmentalized and no clear vision of how to proceed. Yet, in those same few days, the Farm Hall transcripts make it clear that Heisenberg and his student, Carl von Weizsäcker, purposefully constructed a revisionist narrative of their wartime activities. According to them, while the Americans had built a weapon of death and destruction on unprecedented scales, they, the Germans, had deliberately pursued only a nuclear reactor, being unwilling to build a massive new weapon for Hitler’s Reich—thereby placing the responsibility for their failure on their supposed moral clarity, rather than their sheer incompetence.

This was undoubtedly one of symmetry's greatest success stories. Glashow, Wienberg, and Salam managed to unmask the electromagnetic and weak forces by recognizing that underneath the differences in the strengths of these two forces (the electromagnetic force is about a hundred thousand times stronger within the nucleus) and the different masses of the messenger particles lay a remarkable symmetry. The forces of nature take the same form if electrons are interchanged with neutrinos or with any mixture of the two. The same is true when photons are interchanged with the W and Z force-messengers. The symmetry persists even if the mixtures vary from place to place or from time to time. The invariance of the laws under such transformations performed locally in space and time has become known as gauge symmetry. In the professional jargon, a gauge transformation represents a freedom in formulating the theory that has no directly observable effects-in other words, a transformation to which the physical interpretation is insensitive. Just as the symmetry of the laws of nature under any change of the spacetime coordinates requires the existence of gravity, the gauge symmetry between electrons and neutrinos requires the existence of the photons and the W and Z messenger particles. Once again, when the symmetry is put first, the laws practically write themselves. A similar phenomenon, with symmetry dictating the presence of new particle fields, repeats itself with the strong nuclear force.

It was as if we had made something very simple incredibly complicated. Here were these bodies, ready to reproduce, controlled against reproduction, then stimulated for an eventual reproduction that was put on ice. My friends who wanted to prolong their fertility did so, now that they were in their thirties and professionally successful, because circumstances in their lives had not lined up as planned. They had excelled at their jobs. They had nice apartments and enough money to comfortably start a family, but they lacked a domestic companion who would provide the necessary genetic material, lifelong support, and love. They wanted to be the parents they had grown up under, but love couldn't be engineered, and ovaries could. Hanging over all of this was an idea of choice, an arbitrary linking of goals and outcomes, which reduced structural, economic and technological change to individual decision. "The right to choose"―the right to birth control and abortion services―is different from the idea of choice I mean here. I mean that the baby question justified a fiction that one had to conform one's life to a uniform box by a certain deadline. If the choice were only to have a baby or not, then anybody who wanted a baby and was physically able would simply have one (as many people did), but what I saw with my friends was that it wasn’t actually about the choice of having a baby but of setting up a nuclear family, which unfortunately could not, unlike making a baby, happen more or less by fiat.

The world is made of fields—substances spread through all of space that we notice through their vibrations, which appear to us as particles. The electric field and the gravitational field might seem familiar, but according to quantum field theory even particles like electrons and quarks are really vibrations in certain kinds of fields. • The Higgs boson is a vibration in the Higgs field, just as a photon of light is a vibration in the electromagnetic field. • The four famous forces of nature arise from symmetries—changes we can make to a situation without changing anything important about what happens. (Yes, it makes no immediate sense that “a change that doesn’t make a difference” leads directly to “a force of nature” . . . but that was one of the startling insights of twentieth-century physics.) • Symmetries are sometimes hidden and therefore invisible to us. Physicists often say that hidden symmetries are “broken,” but they’re still there in the underlying laws of physics—they’re simply disguised in the immediately observable world. • The weak nuclear force, in particular, is based on a certain kind of symmetry. If that symmetry were unbroken, it would be impossible for elementary particles to have mass. They would all zip around at the speed of light. • But most elementary particles do have mass, and they don’t zip around at the speed of light. Therefore, the symmetry of the weak interactions must be broken. • When space is completely empty, most fields are turned off, set to zero. If a field is not zero in empty space, it can break a symmetry. In the case of the weak interactions, that’s the job of the Higgs field. Without it, the universe would be an utterly different place.   Got

From the Author Matthew 16:25 says, “For whoever desires to save his life will lose it, but whoever loses his life for my sake will find it.”  This is a perfect picture of the life of Nate Saint; he gave up his life so God could reveal a greater glory in him and through him. I first heard the story of Operation Auca when I was eight years old, and ever since then I have been inspired by Nate’s commitment to the cause of Christ. He was determined to carry out God’s will for his life in spite of fears, failures, and physical challenges. For several years of my life, I lived and ministered with my parents who were missionaries on the island of Jamaica. My experiences during those years gave me a passion for sharing the stories of those who make great sacrifices to carry the gospel around the world. As I wrote this book, learning more about Nate Saint’s life—seeing his spirit and his struggles—was both enlightening and encouraging to me. It is my prayer that this book will provide a window into Nate Saint’s vision—his desires, dreams, and dedication. I pray his example will convince young people to step out of their comfort zones and wholeheartedly seek God’s will for their lives. That is Nate Saint’s legacy: changing the world for Christ, one person and one day at a time.   Nate Saint Timeline 1923 Nate Saint born. 1924 Stalin rises to power in Russia. 1930 Nate’s first flight, aged 7 with his brother, Sam. 1933 Nate’s second flight with his brother, Sam. 1936 Nate made his public profession of faith. 1937 Nate develops bone infection. 1939 World War II begins. 1940 Winston Churchill becomes British Prime Minister. 1941 Nate graduates from Wheaton College.

THEORY OF ALMOST EVERYTHING After the war, Einstein, the towering figure who had unlocked the cosmic relationship between matter and energy and discovered the secret of the stars, found himself lonely and isolated. Almost all recent progress in physics had been made in the quantum theory, not in the unified field theory. In fact, Einstein lamented that he was viewed as a relic by other physicists. His goal of finding a unified field theory was considered too difficult by most physicists, especially when the nuclear force remained a total mystery. Einstein commented, “I am generally regarded as a sort of petrified object, rendered blind and deaf by the years. I find this role not too distasteful, as it corresponds fairly well with my temperament.” In the past, there was a fundamental principle that guided Einstein’s work. In special relativity, his theory had to remain the same when interchanging X, Y, Z, and T. In general relativity, it was the equivalence principle, that gravity and acceleration could be equivalent. But in his quest for the theory of everything, Einstein failed to find a guiding principle. Even today, when I go through Einstein’s notebooks and calculations, I find plenty of ideas but no guiding principle. He himself realized that this would doom his ultimate quest. He once observed sadly, “I believe that in order to make real progress, one must again ferret out some general principle from nature.” He never found it. Einstein once bravely said that “God is subtle, but not malicious.” In his later years, he became frustrated and concluded, “I have second thoughts. Maybe God is malicious.” Although the quest for a unified field theory was ignored by most physicists, every now and then, someone would try their hand at creating one. Even Erwin Schrödinger tried. He modestly wrote to Einstein, “You are on a lion hunt, while I am speaking of rabbits.” Nevertheless, in 1947 Schrödinger held a press conference to announce his version of the unified field theory. Even Ireland’s prime minister, Éamon de Valera, showed up. Schrödinger said, “I believe I am right. I shall look an awful fool if I am wrong.” Einstein would later tell Schrödinger that he had also considered this theory and found it to be incorrect. In addition, his theory could not explain the nature of electrons and the atom. Werner Heisenberg and Wolfgang Pauli caught the bug too, and proposed their version of a unified field theory. Pauli was the biggest cynic in physics and a critic of Einstein’s program. He was famous for saying, “What God has torn asunder, let no man put together”—that is, if God had torn apart the forces in the universe, then who were we to try to put them back together?

But so far, we have only discussed applying quantum mechanics to the matter that moves within the gravity fields of Einstein’s theory. We have not discussed a much more difficult question: applying quantum mechanics to gravity itself in the form of gravitons. And this is where we encounter the biggest question of all: finding a quantum theory of gravity, which has frustrated the world’s great physicists for decades. So let us review what we have learned so far. We recall that when we apply the quantum theory to light, we introduce the photon, a particle of light. As this photon moves, it is surrounded by electric and magnetic fields that oscillate and permeate space and obey Maxwell’s equations. This is the reason why light has both particle-like and wavelike properties. The power of Maxwell’s equations lies in their symmetries—that is, the ability to turn electric and magnetic fields into each other. When the photon bumps into electrons, the equation that describes this interaction yields results that are infinite. However, using the bag of tricks devised by Feynman, Schwinger, Tomonaga, and many others, we are able to hide all the infinities. The resulting theory is called QED. Next, we applied this method to the nuclear force. We replaced the original Maxwell field with the Yang-Mills field, and replaced the electron with a series of quarks, neutrinos, etc. Then we introduced a new bag of tricks devised by ’t Hooft and his colleagues to eliminate all the infinities once again. So three of the four forces of the universe could now be unified into a single theory, the Standard Model. The resulting theory was not very pretty, since it was created by cobbling together the symmetries of the strong, weak, and electromagnetic forces, but it worked. But when we apply this tried-and-true method to gravity, we have problems. In theory, a particle of gravity should be called the graviton. Similar to the photon, it is a point particle, and as it moves at the speed of light, it is surrounded by waves of gravity that obey Einstein’s equations. So far, so good. The problem occurs when the graviton bumps into other gravitons and also atoms. The resulting collision creates infinite answers. When one tries to apply the bag of tricks painfully formulated over the last seventy years, we find that they all fail. The greatest minds of the century have tried to solve this problem, but no one has been successful. Clearly, an entirely new approach must be used, since all the easy ideas have been investigated and discarded. We need something truly fresh and original. And that leads us to perhaps the most controversial theory in physics, string theory, which might just be crazy enough to be the theory of everything.

Government is a contrivance of human wisdom to provide for human wants," wrote Edmund Burke in his Reflections on the Revolution in France. In the original and primary sense of lacks or needs, wants tend to structure our vision of government's responsibilities. The quest for security - whether economic, physical, psychological, or military - brings a sense of urgency to politics and is one of the enduring sources of passion in policy controversies. Need is probably the most fundamental political claim. Even toddlers know that need carries more weight than desire or deservingness. They learn early to counter a rejected request by pleading, "I need it." To claim need is to claim that one should be given the resources or help because they are essential. Of course, this raises the question "essential for what?" In conflicts over security, the central issues are what kind of security government should attempt to provide; what kinds of needs it should attempt to meet; and how the burdens of making security a collective responsibility should be distributed. Just as most people are all for equity and efficiency in the abstract, most people believe that society should help individuals and families when they are in dire need. But beneath this consensus is a turbulent and intense conflict over how to distinguish need from mere desire, and how to preserve a work - or - merit based system of economic distribution in the face of distribution according to need. Defining need for purposes of public programs become much an exercise like defining equity and efficiency. People try to portray their needs as being objective, and policymakers seek to portray their program criteria as objective, in order to put programs beyond political dispute. As with equity and efficiency, there are certain recurring strategies of argument that can be used to expand or contract a needs claim. In defense policy, relative need is far more important than absolute. Our sense of national security (and hence our need for weapons) depends entirely on comparison with the countries we perceive as enemies. And here Keynes is probably right: The need for weapons can only be satisfied by feeling superior to "them." Thus, it doesn't matter how many people our warheads can kill or how many cities they can destroy. What matters is what retaliatory capacity we have left after an attack by the other side, or whether our capacity to sustain an offense is greater than their capacity to destroy it. The paradox of nuclear weapons is that the more security we gain in terms of absolute capability (i.e., kill potential), the more insecure we make ourselves with respect to the consequences of nuclear explosions. We gain superiority only by producing weapons we ourselves are terrified to use.

Or think of the tale of the blind men who encounter an elephant for the first time. One wise man, touching the ear of the elephant, declares the elephant is flat and two-dimensional like a fan. Another wise man touches the tail and assumes the elephant is like rope or a one-dimensional string. Another, touching a leg, concludes the elephant is a three-dimensional drum or a cylinder. But actually, if we step back and rise into the third dimension, we can see the elephant as a three-dimensional animal. In the same way, the five different string theories are like the ear, tail, and leg, but we still have yet to reveal the full elephant, M-theory. Holographic Universe As we mentioned, with time new layers have been uncovered in string theory. Soon after M-theory was proposed in 1995, another astonishing discovery was made by Juan Maldacena in 1997. He jolted the entire physics community by showing something that was once considered impossible: that a supersymmetric Yang-Mills theory, which describes the behavior of subatomic particles in four dimensions, was dual, or mathematically equivalent, to a certain string theory in ten dimensions. This sent the physics world into a tizzy. By 2015, there were ten thousand papers that referred to this paper, making it by far the most influential paper in high-energy physics. (Symmetry and duality are related but different. Symmetry arises when we rearrange the components of a single equation and it remains the same. Duality arises when we show that two entirely different theories are actually mathematically equivalent. Remarkably, string theory has both of these highly nontrivial features.) As we saw, Maxwell’s equations have a duality between electric and magnetic fields—that is, the equations remain the same if we reverse the two fields, turning electric fields into magnetic fields. (We can see this mathematically, because the EM equations often contain terms like E2 + B2, which remain the same when we rotate the two fields into each other, like in the Pythagorean theorem). Similarly, there are five distinct string theories in ten dimensions, which can be proven to be dual to each other, so they are really a single eleven-dimensional M-theory in disguise. So remarkably, duality shows that two different theories are actually two aspects of the same theory. Maldacena, however, showed that there was yet another duality between strings in ten dimensions and Yang-Mills theory in four dimensions. This was a totally unexpected development but one that has profound implications. It meant that there were deep, unexpected connections between the gravitational force and the nuclear force defined in totally different dimensions. Usually, dualities can be found between strings in the same dimension. By rearranging the terms describing those strings, for example, we can often change one string theory into another. This creates a web of dualities between different string theories, all defined in the same dimension. But a duality between two objects defined in different dimensions was unheard of.

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.

The revival of MIT’s project, whatever its merits, clearly demonstrated what the combination of old-fashioned Washington horse-trading and new-fangled power — both nuclear and political — can do. Vast promise, little progress A fading poster titled “Fusion, Physics of a Fundamental Energy Source’’ takes up nearly an entire wall of MIT’s Plasma Science & Fusion Department’s second-floor lobby. It reads: “If fusion power plants become practical, they would provide a virtually inexhaustible energy supply . . . substantial progress toward this goal has been made.

You can take the entire world of physics with all of its macrocosm and microcosm, its quantum mechanics and nuclear physics and reduce it to one word: energy. It's all energy. Scientists say that if you can't measure it, weight it, or see it, it doesn't exist. Well, no one has ever seen energy. We can see its effects, but not "it.

How can a man be still if he sees such a great wrong being instigated?' 'It's difficult, but it's necessary,' Professor While insisted. 'Science must go on unhindered, and if we bring politics into our work we will cease to be scientists.' 'Will we cease being human?' MacGregor demanded with the rudeness of justifying himself. 'Should we hand over our affairs to men we despise?' 'I suppose that is unanswerable.' Professor White was an deep into it now as MacGregor. 'But when we dabble in politics we suffer what you are suffering now, and it isn't worth it. Is it?' 'I don't know,' MacGregor said morosely. 'Then why destroy yourself?' 'I don't believe a man has much choice any more,' MacGregor said. 'There seems to be some kind of a battle going on for any existence, science and all.' 'You may be right,' the Professor said. 'We are certainly facing a situation of terrible choice. Only yesterday the physicist chaps back from America brought in a petition to sign against control and secrecy of information and research in nuclear physics. Once they start on this secrecy business there is no telling where it will end. It was bad enough when we were working at Tennessee. We cannot have those ignorant politicians telling us what we must do.' 'They are already telling us what we must do,' MacGregor argued. 'The military control so much research that the phyusicist are becoming straight-out weapon makers and nothing else.' 'It's not the physicists' fault...' 'Then why don't they stop working for the military. Now they are talking about radio-active dust clouds and the biologists are producing concentrates of bacteria for wholesale disease-making. What's the matter with them? Have the Generals got them so scared that they meekly do as they are told?' 'Weapons are a part of life,' the Professor commented sadly, 'and since the politicians refuse to be peaceful, at least they ask for weapons and give us a chance we would not otherwise have of making enormous strides in costly research.' 'Perhaps. But don't we care how the products of our research are used?' 'You are looking for logic where there isn't any,' the Professor said. 'It isn't science which shapes the world, young man.' 'No sir, but we are part of it.' 'Really a very small part of it. The ultimate decision on human affairs lies outside science. We may be part of it, but if you are looking for the deciding factor in the shape of existence then I don't know where you'll find it.

Christianity is not brain surgery or rocket science, it is not quantum mechanics or nuclear physics; it is both infinitely easier and more difficult than all of these. The fragile flame of faith is fanned into life so simply: all we need do is sit still for a few moments, embrace the silence that engulfs us, and invite that flame to burn bright within us.

Science began with a gadget and a trick. The gadget was the wheel; the trick was fire. We have come a long way from the two-wheel cart to the round-the-world transport plane, or from the sparking flint to man-made nuclear fission. Yet I wonder whether the inhabitants of Hiroshima were more aware of the evolution of science than ancient man facing an on-storming battle chariot. It isn't physics that will make this a better life, nor chemistry, nor sociology. Physics may be used to atom-bomb a nation and chemistry may be used to poison a city and sociology has been used to drive people and classes against classes. Science is only an instrument, no more than a stick or fire or water that can be used to lean on or light or refresh, and also can be used to flail or burn or drown. Knowledge without morals is a beast on the loose.

You have to be an optimist to believe in the Singularity,” she says, “and that’s harder than it seems. Have you ever played Maximum Happy Imagination?” “Sounds like a Japanese game show.” Kat straightens her shoulders. “Okay, we’re going to play. To start, imagine the future. The good future. No nuclear bombs. Pretend you’re a science fiction writer.” Okay: “World government … no cancer … hover-boards.” “Go further. What’s the good future after that?” “Spaceships. Party on Mars.” “Further.” “Star Trek. Transporters. You can go anywhere.” “Further.” I pause a moment, then realize: “I can’t.” Kat shakes her head. “It’s really hard. And that’s, what, a thousand years? What comes after that? What could possibly come after that? Imagination runs out. But it makes sense, right? We probably just imagine things based on what we already know, and we run out of analogies in the thirty-first century.” I’m trying hard to imagine an average day in the year 3012. I can’t even come up with a half-decent scene. Will people live in buildings? Will they wear clothes? My imagination is almost physically straining. Fingers of thought are raking the space behind the cushions, looking for loose ideas, finding nothing. “Personally, I think the big change is going to be our brains,” Kat says, tapping just above her ear, which is pink and cute. “I think we’re going to find different ways to think, thanks to computers. You expect me to say that”—yes—“but it’s happened before. It’s not like we have the same brains as people a thousand years ago.” Wait: “Yes we do.” “We have the same hardware, but not the same software. Did you know that the concept of privacy is, like, totally recent? And so is the idea of romance, of course.” Yes, as a matter of fact, I think the idea of romance just occurred to me last night. (I don’t say that out loud.) “Each big idea like that is an operating system upgrade,” she says, smiling. Comfortable territory. “Writers are responsible for some of it. They say Shakespeare invented the internal monologue.” Oh, I am very familiar with the internal monologue. “But I think the writers had their turn,” she says, “and now it’s programmers who get to upgrade the human operating system.” I am definitely talking to a girl from Google. “So what’s the next upgrade?” “It’s already happening,” she says. “There are all these things you can do, and it’s like you’re in more than one place at one time, and it’s totally normal. I mean, look around.” I swivel my head, and I see what she wants me to see: dozens of people sitting at tiny tables, all leaning into phones showing them places that don’t exist and yet are somehow more interesting than the Gourmet Grotto. “And it’s not weird, it’s not science fiction at all, it’s…” She slows down a little and her eyes dim. I think she thinks she’s getting too intense. (How do I know that? Does my brain have an app for that?) Her cheeks are flushed and she looks great with all her blood right there at the surface of her skin. “Well,” she says finally, “it’s just that I think the Singularity is totally reasonable to imagine.

Sometimes it was entirely right and proper to be awed. And recognising the physics in these formations, the hand of time and matter and the nuclear forces underpinning all things, did not lessen that feeling. What

dark matter is probably all around us. The problem is that it plays by different physical rules than ordinary matter. All the subatomic elementary particles which make up ordinary matter—you know, the leptons and quarks, et cetera—they’re all bound together by the strong nuclear force. The candidate particles for dark matter are called WIMPs.” “Physicists come up with the best names.” She smiled. “Well, it’s a field dominated by men. It stands for Weakly Interacting Massive Particles. Like ordinary matter these WIMPs have mass, they’re acted on by the exceedingly faint force of gravity, but because they don’t obey strong nuclear forces they almost never interact or collide with ordinary matter.

As it turned out, the canister was filled with a substance called red mercury—also known as cinnabar—that physically resembles uranium oxide although chemically it is quite different. Red mercury has been used in nuclear scams for more than twenty-five years.

It’s useful to contrast the missileers’ dysfunctional culture with that of their navy counterparts who work in nuclear submarines. At first glance, the two groups seem roughly similar: Both spend vast amounts of time isolated from the rest of society, both are tasked with memorizing and executing tedious protocols, and both are oriented toward Cold War nuclear deterrence missions whose time has passed. Where they differ, however, is in the density of the belonging cues in their respective environments. Sailors in submarines have close physical proximity, take part in purposeful activity (global patrols that include missions beyond deterrence), and are part of a career pathway that can lead to the highest positions in the navy. Perhaps as a result, the nuclear submarine fleet has thus far mostly avoided the kinds of problems that plague the missileers, and in many cases have developed high-performing cultures.

Those whose aggression is masked, or oblique, or unsuccessful, will always condemn it in others. They are likely to think of boxing as “primitive”—as if inhabiting the flesh were not a primitive proposition, radically inappropriate to a civilization supported by and always subordinate to physical strength: missiles, nuclear warheads. The terrible silence dramatized in the boxing ring is the silence of nature before man, before language, when the physical being alone was God. In any case, anger is an appropriate response to certain intransigent facts of life, not a motiveless malignancy as in classic tragedy but a fully motivated and socially coherent impulse. Impotence takes many forms—one of them being the reckless physical expenditure of physical potency.

It is well known in physics that when one compresses the mass of an object its potential energy increases exponentially. Coal is an example of such compression; nuclear fission another. There are several techniques in Qabalah for 'compressing' a text of scripture to 'increase' its 'power.' A book called the Cifri Ali is said to one of the books used by the Bektashis. It is a book revealed to Ali ('Alaihi Assalam) and secretly handed down to his descendants. Learned Şehy's are supposed to have learned from it and therefore to be able to practice divination.

But not every threat is like that. There’s a small category (a list with three items) of physical threats so different in quantity that they become different in quality, their effects so far-reaching that we can’t be confident of surviving them with our civilizations more or less intact. One is large-scale nuclear war; it’s always worth recalling J. Robert Oppenheimer’s words as he watched the first bomb test, quoting from Hindu scripture: “Now I am become Death, the destroyer of worlds.” So far, the cobbled-together and jury-rigged international efforts to forestall an atomic war have worked, and indeed, for much of the last fifty years those safeguards, formal and informal, have seemed to be strengthening.
