Neutron Quotes

Most importantly we have learned that from here on it is success for all or none, for it is experimentally proven by physics that "unity is plural and at minimum two" - the complementary but not mirror-imaged proton and neutron. You and I are inherently different and complimentary. Together we average as zero - that is, as eternity.

Now I've got nothing left to lose You take your time to choose I can tell you now without a trace of fear That my love will be forever And we'll die we'll die together Lie, I will never 'Cause our love will be forever" ~Neutron Star Collision (Love is Forever)

Scientists are slowly waking up to an inconvenient truth - the universe looks suspiciously like a fix. The issue concerns the very laws of nature themselves. For 40 years, physicists and cosmologists have been quietly collecting examples of all too convenient "coincidences" and special features in the underlying laws of the universe that seem to be necessary in order for life, and hence conscious beings, to exist. Change any one of them and the consequences would be lethal. Fred Hoyle, the distinguished cosmologist, once said it was as if "a super-intellect has monkeyed with physics". To see the problem, imagine playing God with the cosmos. Before you is a designer machine that lets you tinker with the basics of physics. Twiddle this knob and you make all electrons a bit lighter, twiddle that one and you make gravity a bit stronger, and so on. It happens that you need to set thirtysomething knobs to fully describe the world about us. The crucial point is that some of those metaphorical knobs must be tuned very precisely, or the universe would be sterile. Example: neutrons are just a tad heavier than protons. If it were the other way around, atoms couldn't exist, because all the protons in the universe would have decayed into neutrons shortly after the big bang. No protons, then no atomic nucleuses and no atoms. No atoms, no chemistry, no life. Like Baby Bear's porridge in the story of Goldilocks, the universe seems to be just right for life.

When he put the old-fashioned mechanical toy on her palm, she stopped breathing. It was a tiny representation of an atom, complete with colored ball bearings standing in for neutrons, protons, and on the outside, arranged on arcs of fine wire, electrons. Turning the key on the side made the electrons move, what she’d thought were ball bearings actually finely crafted spheres of glass that sparked with color. A brilliant, thoughtful, wonderful gift for a physics major. “Why magnesium?” she asked, identifying the atomic number of the light metal. His hand on her jaw, his mouth on her own. “Because it’s beautifully explosive, just like my X.

CARL SAGAN SAID that if you want to make an apple pie from scratch, you must first invent the universe. When he says “from scratch,” he means from nothing. He means from a time before the world even existed. If you want to make an apple pie from nothing at all, you have to start with the Big Bang and expanding universes, neutrons, ions, atoms, black holes, suns, moons, ocean tides, the Milky Way, Earth, evolution, dinosaurs, extinction- level events, platypuses, Homo erectus, Cro- Magnon man, etc. You have to start at the beginning. You must invent fire. You need water and fertile soil and seeds. You need cows and people to milk them and more people to churn that milk into butter. You need wheat and sugar cane and apple trees. You need chemistry and biology. For a really good apple pie, you need the arts. For an apple pie that can last for generations, you need the printing press and the Industrial Revolution and maybe even a poem.To make a thing as simple as an apple pie, you have to create the whole wide world.

The energy in the universe is not in the planets, or in the protons or neutrons, but in the relationship between them.

I felt like a punk who’d gone out to buy a switchblade and come home with a small neutron bomb. "Screwed again", I thought. "What good’s a neutron bomb in a streetfight?

I remember one bobcat they had in here - now bobcats are an endangered species in this neck of the woods - they'd caught it somewhere and they must have put that cat through a dozen rounds of burn experiments before they finally determined that it was utterly useless to them. Like an empty beer can. And then you know what they did to it? Claudius was late for a lunch date so rather thanput the destroyed but still breathing animal to sleep, he picked it up by its hind legs and simply smashed its head against a wall repeatedly until it was dead. How can I forget it: I was the one told to clean up the mess. The head dented in. The eyes slowly closing. The once proud claws hanging down, stunned and lifeless, the utter senselessness of it all, and the hate, a hatred that was consummated in me which is as dangerous a hormone, or chemical, or portion of the brain, as any neutron bomb. Except that I didnt know how to explode. I was like a computer without a keyboard, a bird without wings. Roaring inside. I wanted to kill that man. To do unto others what they had done unto me. I was that bobcat, you better believe it.

The core of a neutron star is so dense that a single spoonful of matter from it would weigh more than 500 billion kilograms.

One proton of faith, three electrons of humility, a neutron of compassion and a bond of honesty,” Robert said, winking at his daughter. “What’s that?” Cora frowned, confused. Maggie laughed. “That, according to your father, is the molecular structure of love.

I'm too drunk to recall much of what I've said. Which, come to think of it, is probably just as well, judging by the way people who are normally quite sensible dissolve into gibbering, rude, opinionated and bombastic idiots once the alcohol molecules in their bloom-stream outnumber the neutrons, or whatever. Luckily, one only notices this if one stays sober oneself, so the solution is as pleasant (at the time, at least) as it is obvious.

So I've tried to make this book as dense as possible, like a neutron star. And if you think I came up with that simile by googling 'What stuff is most dense?', you'd be wrong. I already knew neutron stars were maybe dense before I googled it to make sure.

We all are bundles of electric waves or streams of particles – proton, neutron, and electrons. If a piece of metal can be transformed into electric or magnetic waves, so can a string of sound, a thought, and a desire.

We sometimes hear of things that can travel faster than light. Something called 'the speed of thought' is occasionally proffered. This is an exceptionally silly notion especially since the speed of impulses through the neutrons in our brain is about the same as the speed of a donkey cart.

A proton or neutron is made up of three quarks, one of each color. A proton contains two up quarks and one down quark; a neutron contains two down and one up.

Self-discovery is among the greatest of discoveries, like atoms, electrons and neutrons, which cannot be seen but whose impact can either destroy billions of lives or save them.

These stars marked the moments of the universe. There were aging orange embers, blue dwarfs, twin yellow giants. There were collapsing neutron stars, and angry supernovae that hissed into the icy emptiness. There were borning stars, breathing stars, pulsing stars, and dying stars. There was the Death Star.

Up to about thirty years ago, it was thought that protons and neutrons were “elementary” particles, but experiments in which protons were collided with other protons or electrons at high speeds indicated that they were in fact made up of smaller particles.

Gravity ruled, and gravity did not take into account circumstances, or the unfairness of things, or listen to eleventh-hour petitions before reluctantly repealing its laws. Gravity crushed, and near the surface of a neutron star gravity crushed absolutely, until diamond flowed like water; until a mountain collapsed into a millionth of its height.

There are 4 things in the world, ions ,protons, neutrons and morons!

(The neutron is a bit of a drama queen.)

A good thing? Or a strong omen...Only time would tell what these newfangled neutrons and fission reactions would give to our ever-changing world.In all probability,this new scientific birth would change all of our lives forever and perhaps end the brutal war we were now engaged in?

The Age of the Stars had come to an end. Once in a billion years, a feeble supernova illuminated the vestiges of its home; brown dwarfs, neutron stars, blackholes... lifeless echoes of their former majesty.

Afterwards, the princeps asked the science consul, “Did we destroy a civilization in the microcosmos in this experiment?” “It was at least an intelligent body. Also, Princeps, we destroyed the entire microcosmos. That miniature universe is immense in higher dimensions, and it probably contained more than one intelligence or civilization that never had a chance to express themselves in macro space. Of course, in higher dimensional space at such micro scales, the form that intelligence or civilization may take is beyond our imagination. They’re something else entirely. And such destruction has probably occurred many times before.” “Oh?” “In the long history of scientific progress, how many protons have been smashed apart in accelerators by physicists? How many neutrons and electrons? Probably no fewer than a hundred million. Every collision was probably the end of the civilizations and intelligences in a microcosmos.

Even today, more than eighty years after Oort's bold guess, we still don't have a clue what this dark matter is made of. We know it exists. We know where it is. We have maps of its presence within and around galaxies throughout the universe. We even have stringent constraints on what it is not, but we have no clue what it is. And yes, its presence is overwhelming: for every one kilogram of ordinary matter made out of neutrons and protons and electrons, there are five kilograms of dark matter, made out of who-knows-what.

Some say we are not like humans but we are more like them than we are different. Man and animals are in the same species as mammals as they have mammary glands that produce the milk to nurse their young. Their lungs breathe air and their blood is warm. They are vertebrates in that their skeletal system and well-designed spines hold their bodies together. Each cell is made of molecules, each molecule is made of atoms, and each atom is made of protons, neutrons and mostly electrons, which are made of waves of fibered light.

You fling the book on the floor, you would hurl it out of the window, even out of the closed window, through the slats of the Venetian blinds; let them shred its incongruous quires, let sentences, words, morphemes, phonemes gush forth, beyond recomposition into discourse; through the panes, and if they are of unbreakable glass so much the better, hurl the book and reduce it to photons, undulatory vibrations, polarized spectra; through the wall, let the book crumble into molecules and atoms passing between atom and atom of the reinforced concrete, breaking up into electrons, neutrons, neutrinos, elementary particles more and more minute; through the telephone wires, let it be reduced to electronic impulses, into flow of information, shaken by redundancies and noises, and let it be degraded into a swirling entropy. You would like to throw it out of the house, out of the block, beyond the neighborhood, beyond the city limits, beyond the state confines, beyond the regional administration, beyond the national community, beyond the Common Market, beyond Western culture, beyond the continental shelf, beyond the atmosphere, the biosphere, the stratosphere, the field of gravity, the solar system, the galaxy, the cumulus of galaxies, to succeed in hurling it beyond the point the galaxies have reached in their expansion, where space-time has not yet arrived, where it would be received by nonbeing, or, rather, the not-being which has never been and will never be, to be lost in the most absolutely guaranteed undeniable negativity.

He had already decided that X rays, sonic probes, neutron beams, and all other nondestructive means of investigation would be brought into play before he called up the heavy artillery of the laser. It was the mark of a barbarian to destroy something one could not understand; but perhaps men were barbarians, beside the creatures who had made this thing.

It had to happen to someone. There is nothing exceptional about you, any more than there is about the first neutron that starts the chain reaction in an atomic bomb. It simply happens to be the first. Any other neutron would have served

I have been reading about the Neutron Bomb. I want to be like that, radiant and deadly, a ghost of an impact, to pass through walls, to kill everyone, in flight among the empty houses, punching through molecules like a knife through a paper bag.

Ideally, every single fission reaction should trigger just one more fission in a neighboring atom, so that each successive generation of neutrons contains exactly the same number as the one before, and the reactor remains in the same critical state.

There was, I think, a feeling that the best science was that done in the simplest way. In experimental work, as in mathematics, there was 'style' and a result obtained with simple equipment was more elegant than one obtained with complicated apparatus, just as a mathematical proof derived neatly was better than one involving laborious calculations. Rutherford's first disintegration experiment, and Chadwick's discovery of the neutron had a 'style' that is different from that of experiments made with giant accelerators.

That’s when I felt it. One thin finger. Gently touching my thigh. I kept talking about how alpha loses two protons and two neutrons, like his finger wasn’t on my thigh. And I think he liked that, because he kept asking questions, as if his finger weren’t on my thigh.

More energy is needed to rise a millimetre above a neutron star's surface than to break completely free of Earth's gravity. A pen dropped from a height of one metre would impact with the energy of a ton of TNT (although the intense gravity on a neutron star's surface would actually, of course, squash any such objects instantly). A projectile would need to attain half the speed of light to escape its gravity; conversely, anything that fell freely onto a neutron star from a great height would impact at more than half the speed of light.

I hope to inspire you to recognize that your reason for existence is to pursue the things that excite you the most. The best thing you can do--for yourself and everyone else--is to act on the things you're most passionate about. When you do, you'll shine, and everyone else will see that brilliance. On a biological level, the mirror neutrons of the people around you will activate. They will recognize that they can also follow their dreams and accomplish things they have always wanted to accomplish. On a spiritual level, their souls will remember their reason for being.

The essence of the evening was captured by a question from the audience. Someone asked: “What would it take to change your worldview?” My answer was simple: Any single piece of evidence. If we found a fossilized animal trying to swim between the layers of rock in the Grand Canyon, if we found a process by which a new huge fraction of a radioactive material’s neutrons could become protons in some heretofore fantastically short period of time, if we found a way to create eleven species a day, if there were some way for starlight to get here without going the speed of light, that would force me and every other scientist to look at the world in a new way. However, no such contradictory evidence has ever been found—not any, not ever.

At the end of the day, no matter how confident we are in our observations, our experiments, our data, or our theories, we must go home knowing that 85 percent of all the gravity in the cosmos comes from an unknown, mysterious source that remains completely undetected by all means we have ever devised to observe the universe. As far as we can tell, it’s not made of ordinary stuff such as electrons, protons, and neutrons, or any form of matter or energy that interacts with them. We call this ghostly, offending substance “dark matter,” and it remains among the greatest of all quandaries.

How do I know that a table still exists if I go out of the room and can’t see it? What does it mean to say that things we can’t see, such as electrons or quarks—the particles that are said to make up the proton and neutron—exist? One could have a model in which the table disappears when I leave the room and reappears in the same position when I come back, but that would be awkward, and what if something happened when I was out, like the ceiling falling in? How, under the table-disappears-when-I-leave-the-room model, could I account for the fact that the next time I enter, the table reappears broken, under the debris of the ceiling? The model in which the table stays put is much simpler and agrees with observation. That is all one can ask.

Let us return for a moment to Lady Lovelace’s objection, which stated that the machine can only do what we tell it to do. One could say that a man can "inject" an idea into the machine, and that it will respond to a certain extent and then drop into quiescence, like a piano string struck by a hammer. Another simile would be an atomic pile of less than critical size: an injected idea is to correspond to a neutron entering the pile from without. Each such neutron will cause a certain disturbance which eventually dies away. If, however, the size of the pile is sufficiently increased, the disturbance caused by such an incoming neutron will very likely go on and on increasing until the whole pile is destroyed. Is there a corresponding phenomenon for minds, and is there one for machines? There does seem to be one for the human mind. The majority of them seem to be "sub critical," i.e. to correspond in this analogy to piles of sub-critical size. An idea presented to such a mind will on average give rise to less than one idea in reply. A smallish proportion are supercritical. An idea presented to such a mind may give rise to a whole "theory" consisting of secondary, tertiary and more remote ideas. Animals’ minds seem to be very definitely sub-critical. Adhering to this analogy we ask, "Can a machine be made to be super-critical?

Amazed Generation! Found Generation! Diamond Generation! Brainwashed Generation! Amnesiac T.V. Bureaucracy Voidoids! New Wave Punk Generation! Neutron Bomb blast Babies! Apocalypse Spermatozoa! Did you grow up imbibing Microchip sex waters? Will you marry me in the next Millennium? Must I wait for the Great Year? - Listening to Susan Sontag

As the cosmos continues to cool—dropping below a hundred million degrees—protons fuse with protons as well as with neutrons, forming atomic nuclei and hatching a universe in which ninety percent of these nuclei are hydrogen and ten percent are helium, along with trace amounts of deuterium (“heavy” hydrogen), tritium (even heavier hydrogen), and lithium.

You probably have a bathroom scale that can tell the difference between a 180-pound man and a 185-pound man. I have a scientific scale that can tell the difference between an atom with twelve neutrons and an atom with thirteen neutrons. Actually, I have two such scales. They are called mass spectrometers, and they are worth about half a million dollars each.

Szilard also hoped to talk to Fermi: “I thought that if neutrons are in fact emitted in fission, this fact should be kept secret from the Germans

He wondered which element or elements might emit two or more neutrons for each neutron captured.

What’s wrong?” Kate asked. “Nothing… that’s just my soul collapsing like a neutron star,” Mary said. Kate thought the comparison was a little dramatic. “Why

The core of a neutron star is so dense that a single spoonful of matter from it would weigh 200 billion pounds.

hadrons”—a collective term used by physicists for protons, neutrons and other particles governed by the strong nuclear force.

Hay que mirar las cosas muy atentamente para poder ver los electrones. Son esas cositas minúsculas que parecen sonrisas diminutas. Los neutrones son grises y parecen ceños fruncidos.

[Joffe], during a visit to Russia, complained to his KGB handler about the awful coffee. The KGB dude replied that it was really the Kremlin's answer to America's neutron bomb -- both killed people but left the building intact. "I was then that I first saw this vision,"said Joffe. Bad coffee equals expansionism, imperialism, and war; good coffee drips with civility and pacifism and lassitude...

What remains of your past if you didn't allow yourself to feel it when it happened? If you don't have your experiences in the moment, if you gloss over them with jokes or zoom past them, you end up with curiously dispassionate memories. Procedural and depopulated. It's as if a neutron bomb went off and all you're left with are hospital corridors, where you're scanning the walls for familiar photographs.

There was the flu that exploded like a neutron bomb over the surface of the earth and the shock of the collapse that followed, the first unspeakable years when everyone was traveling, before everyone caught on that there was no place they could walk to where life continued as it had before and settled wherever they could, clustered close together for safety in truck stops and former restaurants and old motels.

Far from being empty, space is more like a snooker table. Stars explode or collide and that’s the white ball being smacked with the cue stick. Individual atoms go flying off at close to the speed of light. Regardless of how small they are, anything traveling that fast is dangerous. Even though space is a vacuum, given enough time, atoms will eventually collide with each other and—bang—the cosmic game of snooker just got interesting. Protons, neutrons and electrons scatter again, speeding along until they hit something else. If that something else happens to be alive, that’s bad—destroying cell walls and damaging DNA.

The discovery of slow-neutron radioactivity meant that Fermi’s group had to work its way through the elements again looking for different and enhanced half-lives—which is to say, different isotopes and decay products.

So Fermi said, “Well . . . there is the remote possibility that neutrons may be emitted in the fission of uranium and then of course perhaps a chain reaction can be made.” Rabi said, “What do you mean by ‘remote possibility’?” and Fermi said, “Well, ten per cent.” Rabi said, “Ten per cent is not a remote possibility if it means that we may die of it. If I have pneumonia and the doctor tells me that there is a remote possibility that I might die, and it’s ten percent, I get excited about it.

Fermi allowed himself a grin. He would tell the technical council the next day that the pile achieved a k of 1.0006.1700 Its neutron intensity was then doubling every two minutes. Left uncontrolled for an hour and a half, that rate of increase would have carried it to a million kilowatts.

They needed to understand how neutrons would diffuse through the core and the tamper. They needed a theory of the explosion’s hydrodynamics—the complex dynamic motions of its fluids, which the core and tamper would almost instantly become as their metals heated from solid to liquid to gas.

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.

The numerals 666 are most often identified with the Beast of Revelation, but they are also symbolic of the fact that we live in a carbon-based universe.  An atom of carbon features six protons, six neutrons and six electrons.  In other words, this universe we live in is coded in 666 by the very nature of what it is.

The pile as it waited in the dark cold of Chicago winter to be released to the breeding of neutrons and plutonium contained 771,000 pounds of graphite, 80,590 pounds of uranium oxide and 12,400 pounds of uranium metal. It cost about $1 million to produce and build. Its only visible moving parts were its various control rods.

They had discovered the reason no elements beyond uranium exist naturally in the world: the two forces working against each other in the nucleus eventually cancel each other out. They pictured the uranium nucleus as a liquid drop gone wobbly with the looseness of its confinement and imagined it hit by even a barely energetic slow neutron. The neutron would add its energy to the whole. The nucleus would oscillate. In one of its many random modes of oscillation it might elongate. Since the strong force operates only over extremely short distances, the electric force repelling the two bulbs of an elongated drop would gain advantage. The two bulbs would push farther

Let us return for a moment to Lady Lovelace’s objection, which stated that the machine can only do what we tell it to do.

Now let us say our morning pledge together,” said the mysterious professor from his position on the branch. All the glowing star-children seemed to place their little hands over their unidentified middles. Even Tuntuni placed a yellow wing over his chest. “We pledge allegiance to the element hydrogen, and also its partner, helium,” chanted the little star-lings. Neel and I giggled from the back row like we were the classroom delinquents. Luckily, no one seemed to hear us, and the stars kept pledging allegiance. “And to the principle of nuclear fusion. Luminous light, born from dust, nebula to stars, red giants to supernova, white dwarf, neutron star, or black hole!

We use the effect of centrifugal forces on matter to offer insight into the rotation rate of extreme cosmic objects. Consider pulsars. With some rotating at upward of a thousand revolutions per second, we know that they cannot be made of household ingredients, or they would spin themselves apart. In fact, if a pulsar rotated any faster, say 4,500 revolutions per second, its equator would be moving at the speed of light, which tells you that this material is unlike any other. To picture a pulsar, imagine the mass of the Sun packed into a ball the size of Manhattan. If that’s hard to do, then maybe it’s easier if you imagine stuffing about a hundred million elephants into a Chapstick casing. To reach this density, you must compress all the empty space that atoms enjoy around their nucleus and among their orbiting electrons. Doing so will crush nearly all (negatively charged) electrons into (positively charged) protons, creating a ball of (neutrally charged) neutrons with a crazy-high surface gravity. Under such conditions, a neutron star’s mountain range needn’t be any taller than the thickness of a sheet of paper for you to exert more energy climbing it than a rock climber on Earth would exert ascending a three-thousand-mile-high cliff. In short, where gravity is high, the high places tend to fall, filling in the low places—a phenomenon that sounds almost biblical, in preparing the way for the Lord: “Every valley shall be raised up, every mountain and hill made low; the rough ground shall become level, the rugged places a plain” (Isaiah 40:4). That’s a recipe for a sphere if there ever was one. For all these reasons, we expect pulsars to be the most perfectly shaped spheres in the universe.

Anna took love very seriously. She loved love. No, worshipped, that's the word. She worshipped love. That was the only thing which had any place in her life. That and hatred. Do you know what neutron stars are?' 'They're planets with such compactness and high surface gravity that if I dropped this cigarette on one of them it would strike with the same force as an atom bomb. It was the same with Anna. Her gravitation to love-and hatred-was so strong that nothing could exist in the space between them. Every tiny detail caused an atomic explosion. Do you understand? It took me time to understand. She was like Jupiter-hidden behind an eternal cloud of sulphur. And humour. And sexuality.

We have seen recursion in the grammars of languages, we have seen recursive geometrical trees, which grow upwards forever, and we have seen one way in which recursion enters the theory of solid state physics. Now we are going to see yet another way in which the whole world is built out of recursion. This has to do with the structure of elementary particles: electrons, protons, neutrons, and the tiny quanta of electromagnetic radiation called "photons". We are going to see that particles are - in a certain sense which can only be defined rigorously in relativistic quantum mechanics- nested inside each other in a way which can be described recursively, perhaps even by some sort of "grammar".

Busloads of visitors from Los Alamos and beyond had begun arriving at Compañia Hill, the viewing site twenty miles northwest of Zero, at 0200. Ernest Lawrence was there, Hans Bethe, Teller, Serber, Edwin McMillan, James Chadwick come to see what his neutron was capable of and a crowd of other men, including Trinity staff no longer needed down on the plain.

I have them all beat: I opened the safes which contained all the secrets to the atomic bomb: the schedules for the production of the plutonium, the purification procedures, how much material is needed, how the bomb works, how the neutrons are generated, what the design is, the dimensions—the entire information that was known at Los Alamos: the whole schmeer!

—¿Alguna vez te has preguntado lo que ocurre cuando muere una estrella? Liam duda y finalmente sacude la cabeza. —La verdad es que no. —Las estrellas transforman el hidrógeno en helio para brillar. Cuando ese hidrógeno se acaba y el núcleo solo es de helio, la estrella se vuelve más fría y más brillante. Hay una explosión. Se muere y sus restos originan una estrella de neutrones. A eso se le conoce como «supernova». Es una de las posibilidades. La otra es que aparezca un agujero negro. —Ni siquiera pestañeo—. A eso se refería mi padre. Nuestros malos momentos están representados por estrellas. Podemos elegir entre aprender algo de ellos, convertirnos en supernovas y volvernos mejores, o simplemente dejar que nos arrastren.

(Because neutrons have no charge, they aren’t repelled by the electrical fields at the heart of an atom and thus could be fired like tiny torpedoes into an atomic nucleus, setting off the destructive process known as fission.) Had the neutron been isolated in the 1920s, they note, it is “very likely the atomic bomb would have been developed first in Europe, undoubtedly by the Germans.” As

How can you spend your days just damning people? Man, where do you think we are right now? Not just right here, but here, alive on this planet? This is hell, Brother, look around. It doesn’t have to be, but we make it so. I can even prove it. All life on this planet is carbon-based, right? Do you know what the atomic number of carbon is? Six. That means six electrons, six neutrons, and six protons, 666, the mark of the beast is the illusion of matter! Who was cast out of paradise? Lucifer, right? Well, guess who else was kicked out? We were, Adam and Eve, eating the forbidden fruit, the Tree of Knowledge, driven from the garden like varmints. We’re the beast. DNA is the coil of the serpent. Duh. Hell is separation from the Source, man. Dig?” “Right on,” Manny spoke up. “I can dig that.

I come from the depths of infinity and from all directions of space-time. I traveled through dark tunnels, went through solar storms. I went straight, circled, parallel, rotated as a spiral. Cosmic clouds trapped me and escaped from them. Avoided collisions with meteories. I was helped by exotic particles, neutron stars and the love of gravity. Every leaf, every flower, every mountain and lake, every cloud and every star and every atom recognize me and greet me. I feel that i have live for million lifetimes. Who am i? What is my purpose? Last night i sent a question into universe, asking ”who am i or am i not? The universe responded immediately: ”You asked me the same thing billions of years ago. And then and now i answer: You’re the smile of no birth and no death, The Hidden Law!

By habit we perceive ourselves and the world around us as solid, real, and enduring. Yet without much effort, we can easily determine that not one aspect within the whole world’s system exists independent of change. I had just been in one physical location, and now I was in another; I had experienced different states of mind. We have all grown from babies to adults, lost loved ones, watched children grow, known changes in weather, in political regimes, in styles of music and fashion, in everything. Despite appearances, no aspect of life ever stays the same. The deconstruction of any one object—no matter how dense it appears, such as an ocean liner, our bodies, a skyscraper, or an oak tree—will reveal the appearance of solidity to be as illusory as permanence. Everything that looks substantial will break down into molecules, and into atoms, and into electrons, protons, and neutrons. And every phenomenon exists in interdependence with myriad other forms. Every identification of any one form has meaning only in relationship to another. Big only has meaning in relation to small. To mistake our habitual misperceptions for the whole of reality is what we mean by ignorance, and these delusions define the world of confusion, or samsara.

When, five years later, the great Robert Oppenheimer turned his attention to neutron stars in a landmark paper, he made not a single reference to any of Zwicky’s work even though Zwicky had been working for years on the same problem in an office just down the hall. Zwicky’s deductions concerning dark matter wouldn’t attract serious attention for nearly four decades. We can only assume that he did a lot of pushups in this period.

For example, life itself is supposedly understandable in principle from the movements of atoms, and those atoms are made out of neutrons, protons and electrons. I must immediately say that when we state that we understand it in principle, we only mean that we think that, if we could figure everything out, we would find that there is nothing new in physics which needs to be discovered in order to understand the phenomena of life. Another

Neutrons don’t influence an atom’s identity, but they do add to its mass. The number of neutrons is generally about the same as the number of protons, but they can vary up and down slightly. Add a neutron or two and you get an isotope. The terms you hear in reference to dating techniques in archeology refer to isotopes—carbon-14, for instance, which is an atom of carbon with six protons and eight neutrons (the fourteen being the sum of the

A year after that, the great red star, its waist now nearly to Jupiter, all at once collapsed in on itself and exploded into a supernova that vaporized every remaining planet, asteroid, and comet of the eighteenth planetary system of the third spiral arm of the Milky Way galaxy. A beautiful magenta-and-yellow wash spread through space, like spilled watercolors. Sensors aboard the hundreds of starliners recorded the event, but even just a short time later, when the Second Fleet would awaken near Delphi, those brilliant clouds would already be gone, and only a small, cold neutron star would remain, a celestial gravestone to humanity’s birthplace. But here, in this final moment . . . As arcs of plasma glowed . . . As stardust glittered . . . As rare elements formed in the atomic foam . . . A fleet of silent black ships, flickering like droplets, moved swiftly into the storm they had secretly created, and got to work.

The simplest form of nuclear reactor requires no equipment at all. If the right quantity of uranium 235 is gathered in the presence of a neutron moderator—water, for example, or graphite, which slows down the movement of the uranium neutrons so that they can strike one another—a self-sustaining chain reaction will begin, releasing molecular energy as heat. The ideal combination of circumstances required for such an event—a criticality—has even aligned spontaneously in nature: in ancient subterranean deposits of uranium found in the African nation of Gabon, where groundwater acted as a moderator. There, self-sustaining chain reactions began underground two billion years ago, producing modest quantities of heat energy—an average of around 100 kilowatts, or enough to light a thousand lightbulbs—and continued intermittently for as long as a million years, until the available water was finally boiled away by the heat of fission.

The official Los Alamos history measures the significance of Frisch’s Dragon-tickling: These experiments gave direct evidence of an explosive chain reaction. They gave an energy production of up to twenty million watts, with a temperature rise in the hydride up to 2°C per millisecond. The strongest burst obtained produced 1015 neutrons. The dragon is of historical importance. It was the first controlled nuclear reaction which was supercritical with prompt neutrons alone.

This core of enriched uranium, approximately the size of a cantaloupe, would weigh about thirty-three pounds. They could also construct a weapon from the even heavier element of plutonium—produced via a neutron-capture process using U-238. A plutonium bomb would need far less critical mass, and the plutonium core might therefore weigh only eleven pounds and appear no larger than an orange. Either core would need to be packed within a thick shell of ordinary uranium the size of a basketball.

Time: 0529:45. The firing circuit closed; the X-unit discharged; the detonators at thirty-two detonation points simultaneously fired; they ignited the outer lens shells of Composition B; the detonation waves separately bulged, encountered inclusions of Baratol, slowed, curved, turned inside out, merged to a common inward-driving sphere; the spherical detonation wave crossed into the second shell of solid fast Composition B and accelerated; hit the wall of dense uranium tamper and became a shock wave and squeezed, liquefying, moving through; hit the nickel plating of the plutonium core and squeezed, the small sphere shrinking, collapsing into itself, becoming an eyeball; the shock wave reaching the tiny initiator at the center and swirling through its designed irregularities to mix its beryllium and polonium; polonium alphas kicking neutrons free from scant atoms of beryllium: one, two, seven, nine, hardly more neutrons drilling into the surrounding plutonium to start the chain reaction.

The object of the project,” Serber said, “is to produce a practical military weapon in the form of a bomb in which the energy is released by a fast-neutron chain reaction in one or more of the materials known to show nuclear fission.” Summarizing what Oppenheimer’s team had learned from their Berkeley summer sessions, Serber reported that by their calculations an atomic bomb might conceivably produce an explosion equivalent to 20,000 tons of TNT. Any such “gadget,” however, would need highly enriched

Zwicky also was the first to recognize that there wasn’t nearly enough visible mass in the universe to hold galaxies together and that there must be some other gravitational influence—what we now call dark matter. One thing he failed to see was that if a neutron star shrank enough it would become so dense that even light couldn’t escape its immense gravitational pull. You would have a black hole. Unfortunately, Zwicky was held in such disdain by most of his colleagues that his ideas attracted almost no notice

We have already seen that gauge symmetry that characterizes the electroweak force-the freedom to interchange electrons and neturinos-dictates the existence of the messenger electroweak fields (photon, W, and Z). Similarly, the gauge color symmetry requires the presence of eight gluon fields. The gluons are the messengers of the strong force that binds quarks together to form composite particles such as the proton. Incidentally, the color "charges" of the three quarks that make up a proton or a neutron are all different (red, blue, green), and they add up to give zero color charge or "white" (equivalent to being electrically neutral in electromagnetism). Since color symmetry is at the base of the gluon-mediated force between quarks, the theory of these forces has become known as quantum chromodynamics. The marriage of the electroweak theory (which describes the electromagnetic and weak forces) with quantum chromodynamics (which describes the strong force) produced the standard model-the basic theory of elementary particles and the physical laws that govern them.

In our profession, we tend to name things exactly as we see them. Big red stars we call red giants. Small white stars we call white dwarfs. When stars are made of neutrons, we call them neutron stars. Stars that pulse, we call them pulsars. In biology they come up with big Latin words for things. MDs write prescriptions in a cuneiform that patients can’t understand, hand them to the pharmacist, who understands the cuneiform. It’s some long fancy chemical thing, which we ingest. In biochemistry, the most popular molecule has ten syllables—deoxyribonucleic acid! Yet the beginning of all space, time, matter, and energy in the cosmos, we can describe in two simple words, Big Bang. We are a monosyllabic science, because the universe is hard enough. There is no point in making big words to confuse you further. Want more? In the universe, there are places where the gravity is so strong that light doesn’t come out. You fall in, and you don’t come out either: black hole. Once again, with single syllables, we get the whole job done. Sorry, but I had to get all that off my chest.

I am Ding Yi.” He opened up two folding chairs and motioned for us to sit down, then returned to his chair. He said, “Before you tell me why you’ve come, let me discuss with you a dream I’ve just had.… No, you’ve got to listen. It was a wonderful dream, which you interrupted. In the dream I was sitting here, a knife in my hand, around so long, like for cutting watermelon. Next to me was this tea table. But there wasn’t an ashtray or anything on it. Just two round objects, yea big. Circular, spherical. What do you think they were?” “Watermelon?” “No, no. One was a proton, the other a neutron. A watermelon-sized proton and neutron. I cut the proton open first. Its charge flowed out onto the table, all sticky, with a fresh fragrance. After I cut the proton in half, the quarks inside tumbled out, tinkling. They were about the size of walnuts, in all sorts of colors. They rolled about on the table, and some of them fell onto the floor. I picked up a white one. It was very hard, but with effort, I was able to bite into it. It tasted like a manaizi grape.… And right then, you woke me up.

Have you ever pondered of the following: Space is a home for the Universe. The Universe is a home for its Galaxies. The Milky Way Galaxy is a home for the Solar System. The Solar System is a home for our planet. The Earth is a home for organic life forms. Your house or apartment is your home. Your body is a home for your soul; and yet for trillions of cells your organism consists of. A cell is a home for its molecules. A molecule is a home for its atoms. An atom is a home for its components, such as protons, electrons, and neutrons. Etc. The world is all about homes!

People are somewhat gorgeous collections of chemical fires, aren't they? Cells and organs burn and smolder, each one, and hot electricity flows and creates storms of further currents, magnetisms and species of gravity--we are towers of kinds of fires, down to the tiniest constituents of ourselves, whatever those are, those things burn like stars in space, in helpless mimicry of the vastness out there, electrons and neutrons, planets and suns, so that we are made of universes of fires contained in skin and placed in turn within a turning and lumbering universe of fires...

Landau pointed out that there was another possible final state for a star, also with a limiting mass of about one or two times the mass of the sun but much smaller even than a white dwarf. These stars would be supported by the exclusion principle repulsion between neutrons and protons, rather than between electrons. They were therefore called neutron stars. They would have a radius of only ten miles or so and a density of hundreds of millions of tons per cubic inch. At the time they were first predicted, there was no way that neutron stars could be observed. They were not actually detected until much later.

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.

During World War II, there had been a project to sabotage the Nazi nuclear weapons program. Years earlier, Leo Szilard, the first person to realize the possibility of a fission chain reaction, had convinced Fermi not to publish the discovery that purified graphite was a cheap and effective neutron moderator. Fermi had wanted to publish, for the sake of the great international project of science, which was above nationalism. But Szilard had persuaded Rabi, and Fermi had abided by the majority vote of their tiny three-person conspiracy. And so, years later, the only neutron moderator the Nazis had known about was deuterium. The only deuterium source under Nazi control had been a captured facility in occupied Norway, which had been knocked out by bombs and sabotage, causing a total of twenty-four civilian deaths. The Nazis had tried to ship the deuterium already refined to Germany, aboard a civilian Norwegian ferry, the SS Hydro. Knut Haukelid and his assistants had been discovered by the night watchman of the civilian ferry while they were sneaking on board to sabotage it. Haukelid had told the watchman that they were escaping the Gestapo, and the watchman had let them go. Haukelid had considered warning the night watchman, but that would have endangered the mission, so Haukelid had only shaken his hand. And the civilian ship had sunk in the deepest part of the lake, with eight dead Germans, seven dead crew, and three dead civilian bystanders. Some of the Norwegian rescuers of the ship had thought the German soldiers present should be left to drown, but this view had not prevailed, and the German survivors had been rescued. And that had been the end of the Nazi nuclear weapons program. Which was to say that Knut Haukelid had killed innocent people. One of whom, the night watchman of the ship, had been a good person. Someone who'd gone out of his way to help Haukelid, at risk to himself; from the kindness of his heart, for the highest moral reasons; and been sent to drown in turn. Afterward, in the cold light of history, it had looked like the Nazis had never been close to getting nuclear weapons after all. And Harry had never read anything suggesting that Haukelid had acted wrongly.

The non-event is not when nothing happens. It is, rather, the realm of perpetual change, of a ceaseless updating, of an incessant succession in real time, which produces this general equivalence, this indifference, this banality that characterizes the zero degree of the event. A perpetual escalation that is also the escalation of growth - or of fashion, which is pre-eminently the field of compulsive change and built-in obsolescence. The ascendancy of models gives rise to a culture of difference that puts an end to any historical continuity. Instead of unfolding as part of a history, things have begun to succeed each other in the void. A profusion of language and images before which we are defenceless, reduced to the same powerlessness, to the same paralysis as we might show on the approach of war. It isn't a question of disinformation or brainwashing. It was a naIve error on the part of the FBI to attempt to create a Disinformation Agency for purposes of managed manipulation - a wholly useless undertaking, since disinformation comes from the very profusion of information, from its incantation, its looped repetition, which creates an empty perceptual field, a space shattered as though by a neutron bomb or by one of those devices that sucks in all the oxygen from the area of impact. It's a space where everything is pre-neutralized, including war, by the precession of images and commentaries, but this is perhaps because there is at bottom nothing to say about something that unfolds, like this war, to a relentless scenario, without a glimmer of uncertainty regarding the final outcome.

The collapsing star pushes past the resistance of crushed electrons, past the resistance of the neutrons. When the stellar material is compressed enough, the curves in spacetime around the collapsing mass become so sharp that even light can be caught in orbit. As collapse continues, light cannot escape the surface, as though the spacetime spills behind the crushed material faster than light can race outward. A horizon defining the region of no return, the event horizon, is inscribed in the very geometry of spacetime. The event horizon casts a lightless shadow, and a black hole has formed. The black hole is not a star anymore. It’s not really even a thing. The pulverized matter that cast the shadow of the event horizon continues to fall and is gone. The black hole is nothing but its shadow. Wheeler

There are no roads in British Columbia. There are only corners joined together. And nowhere is this truer than in Vancouver. In this city, pedestrians, even those within clearly marked crosswalks -- especially those within clearly marked crosswalks -- are viewed not as nuisances to be avoided but as obstacles to be overcome. Rising to the challenge, Vancouver drivers will attempt to weave through these pedestrians without knocking any over -- and, here's the fun part, without ever applying the brakes. Swoosh, swoosh: downtown slalom. Pedestrians, in turn, try to keep things interesting by crisscrossing the streets at random, like neutrons in a particle accelerator. They cross the street like this because, being from Vancouver, they naturally have a sense of entitlement. Either that or they're stoned.

the most elementary material constituent, atoms consist of a nucleus, containing protons and neutrons, that is surrounded by a swarm of orbiting electrons. For a while many physicists thought that protons, neutrons, and electrons were the Greeks' "atoms." But in 1968 experimenters at the Stanford Linear Accelerator Center, making use of the increased capacity of technology to probe the microscopic depths of matter, found that protons and neutrons are not fundamental, either. Instead they showed that each consists of three smaller particles, called quarks—a whimsical name taken from a passage in James Joyce's Finnegans Wake by the theoretical physicist Murray Gell-Mann, who previously had surmised their existence. The experimenters confirmed that quarks themselves come in two varieties, which were named, a bit less creatively, up and down. A proton consists of two up-quarks and a down-quark; a neutron consists of two down-quarks and an up-quark.

The formula presents a symbol of the self, for the self is not just a static quantity or constant form, but is also a dynamic process. In the same way, the ancients saw the imago Dei in man not as a mere imprint, as a sort of lifeless, stereotyped impression, but as an active force. The four transformations represent a process of restoration or rejuvenation taking place, as it were, inside the self, and comparable to the carbon-nitrogen cycle in the sun, when a carbon nucleus captures four protons (two of which immediately become neutrons) and releases them at the end of the cycle in the form of an alpha particle. The carbon nucleus itself comes out of the reaction unchanged, “like the Phoenix from the ashes.”108 The secret of existence, i.e., the existence of the atom and its components, may well consist in a continually repeated process of rejuvenation, and one comes to similar conclusions in trying to account for the numinosity of the archetypes.

Moment, momentum, momentous If you reduce sports to its smallest discrete units, its subatomic particles, you're left with protons and electrons and neutrons called moments. They're the building blocks of every season, every game, every series of downs. Two or more moments may accrete into something more, a propulsive energy called momentum, which in turn can snowball into something greater still, that which is momentous. Consider those consecutive moments last Aug. 4 (2012 summer Olympics) in London, when Michael Phelps-in his final Olympic race-caught and then overtook Japan's Takeshi Matsuda on the butterfly leg of the men's 4 x 100 medley relay. Momentum passed to Phelps's U.S. teammate Nathan Adrian, who pulled away on the freestyle leg, sealing a victory that yielded Phelps's 18th gold medal, and 22nd medal overall, more than any other Olympian in history. It was like the conjugation of some Latin verb: moment, momentum, momentous. Or if you prefer: Veni, vidi, vici (we came, we saw, we conquered). From "moments of the year

Let us pause for a moment and consider the structure of the atom as we know it now. Every atom is made from three kinds of elementary particles: protons, which have a positive electrical charge; electrons, which have a negative electrical charge; and neutrons, which have no charge. Protons and neutrons are packed into the nucleus, while electrons spin around outside. The number of protons is what gives an atom its chemical identity. An atom with one proton is an atom of hydrogen, one with two protons is helium, with three protons is lithium, and so on up the scale. Each time you add a proton you get a new element. (Because the number of protons in an atom is always balanced by an equal number of electrons, you will sometimes see it written that it is the number of electrons that defines an element; it comes to the same thing. The way it was explained to me is that protons give an atom its identity, electrons its personality.) Neutrons don't influence an atom's identity, but they do add to its mass. The number of neutrons is generally about the same as the number of protons, but they can vary up and down slightly. Add a neutron or two and you get an isotope. The terms you hear in reference to dating techniques in archeology refer to isotopes—carbon-14, for instance, which is an atom of carbon with six protons and eight neutrons (the fourteen being the sum of the two). Neutrons and protons occupy the atom's nucleus. The nucleus of an atom is tiny—only one millionth of a billionth of the full volume of the atom—but fantastically dense, since it contains virtually all the atom's mass. As Cropper has put it, if an atom were expanded to the size of a cathedral, the nucleus would be only about the size of a fly—but a fly many thousands of times heavier than the cathedral. It was this spaciousness—this resounding, unexpected roominess—that had Rutherford scratching his head in 1910. It is still a fairly astounding notion to consider that atoms are mostly empty space, and that the solidity we experience all around us is an illusion. When two objects come together in the real world—billiard balls are most often used for illustration—they don't actually strike each other. “Rather,” as Timothy Ferris explains, “the negatively charged fields of the two balls repel each other . . . were it not for their electrical charges they could, like galaxies, pass right through each other unscathed.” When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimeter), your electrons and its electrons implacably opposed to any closer intimacy.

If we ascribe the ejection of the proton to a Compton recoil from a quantum of 52 x 106 electron volts, then the nitrogen recoil atom arising by a similar process should have an energy not greater than about 400,000 volts, should produce not more than about 10,000 ions, and have a range in the air at N.T.P. of about 1-3mm. Actually, some of the recoil atoms in nitrogen produce at least 30,000 ions. In collaboration with Dr. Feather, I have observed the recoil atoms in an expansion chamber, and their range, estimated visually, was sometimes as much as 3mm. at N.T.P. These results, and others I have obtained in the course of the work, are very difficult to explain on the assumption that the radiation from beryllium is a quantum radiation, if energy and momentum are to be conserved in the collisions. The difficulties disappear, however, if it be assumed that the radiation consists of particles of mass 1 and charge 0, or neutrons. The capture of the a-particle by the Be9 nucleus may be supposed to result in the formation of a C12 nucleus and the emission of the neutron. From the energy relations of this process the velocity of the neutron emitted in the forward direction may well be about 3 x 109 cm. per sec. The collisions of this neutron with the atoms through which it passes give rise to the recoil atoms, and the observed energies of the recoil atoms are in fair agreement with this view. Moreover, I have observed that the protons ejected from hydrogen by the radiation emitted in the opposite direction to that of the exciting a-particle appear to have a much smaller range than those ejected by the forward radiation. This again receives a simple explanation on the neutron hypothesis.

Las locas repiten que ni siquiera tenían pagado el plan, y así como así, se les prendía todo los accesos a las redes. Las locas estaban cagadas de la risa. Se acercaban a le chique y se alejaban de le chique, se apagaba y se prendía el sistema, así que así se empezó a correr la voz del caso de le chique. Dicen que todas empezaron a preguntarse cómo, por qué con qué, a le chique le pasaba esto, pero cada vez mejor. Al principio a centímetros de elle, después a metros y después a más distancia. Como que se fue alimentando el poder que tenía porque cada vez la conexión era más fuerte, estable. De a poco entre la comunidad se fue corriendo la voz, de los poderes de le chique. De que había nacido une chique con esta energía, con este poder en su cuerpo. Mis amigas travestis totalmente dislocadas, me cuentan que las locas empezaron a creer que la cosa era como científica, imaginaban que no sé por qué razón, a le niñe se le formaron dentro de la guata de su madre, hilos de electricidad entre los músculos que ahora son capaces de transmitir acceso a las redes sociales, o que tiene en su sangre protones y neutrones, minerales eléctricos, concentraciones de cobre y litio entre el calcio de las células, dicen, algo super posible a esta altura de la vida. Que sus células tienen la capacidad de adaptarse mágicamente al medio ambiente. El cuento es que empezaron a decir que había nacido ese chique con esa capacidad de distribuir cada vez a más gente, wifi y todas las redes sociales. Dicen que de a poco la empezaron a querer, a pesar de ser tan piola. [...] Sí, así, dicen que empezó a ser seguida por un montón de gente. Dicen también, que cuando le preguntan a la gente cómo se llama, cómo es o dónde vive, nadie sabe decir nada, porque la cuidan. No quieren que la pillen las autoridades y la vayan a tomar presa, así que la que sabe, sabe. Pero hay que ser piola, porque dicen que como cada vez más gente está teniendo Facebook, Instagram, y Tinder gratis, lo mas seguro es que las compañías de las telecomunicaciones, empiecen a perseguirla y la acusen de terrorista, de criminal, por hacer que los millonarios de las comunicaciones transnacionales pierdan millones de dólares. —Para no morir tan sola.
