Neutrons Quotes

“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.”

“In the eighteenth century it was often convenient to regard man as a clockwork automaton. In the nineteenth century, with Newtonian physics pretty well assimilated and a lot of work in thermodynamics going on, man was looked on as a heat engine, about 40 per cent efficient. Now in the twentieth century, with nuclear and subatomic physics a going thing, man had become something which absorbs X-rays, gamma rays and neutrons.”

“Jenny Offill's Dept. of Speculation resembles no book I've read before. If I tell you that it's funny, and moving, and true; that it's as compact and mysterious as a neutron; that it tells a profound story of love and parenthood while invoking (among others) Keats, Kafka, Einstein, Russian cosmonauts, and advice for the housewife of 1896, will you please simply believe me, and read it?”

“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.”

“It's becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new ideas on particle physics. The energies in the Big Bang were far higher than we can ever achieve on Earth. So by looking at evidence for the Big Bang, and by studying things like neutron stars, we are in effect learning something about fundamental physics.”

“With all reserve we advance the view that a supernova represents the transition of an ordinary star into a neutron star consisting mainly of neutrons. Such a star may possess a very small radius and an extremely high density. As neutrons can be packed much more closely than ordinary nuclei and electrons, the gravitational packing energy in a cold neutron star may become very large, and under certain conditions may far exceed the ordinary nuclear packing fractions.”

“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.”

“Over the last century, physicists have used light quanta electrons, alpha particles, X-rays, gamma-rays, protons, neutrons and exotic sub-nuclear particles for this purpose. Much important information about the target atoms or nuclei or their assemblage has been obtained in this way. In witness of this importance one can point to the unusual concentration of scattering enthusiasts among earlier Nobel Laureate physicists. One could say that physicists just love to perform or interpret scattering experiments.”

“Mathematics is not only real, but it is the only reality. That is that entire universe is made of matter, obviously. And matter is made of particles. It's made of electrons and neutrons and protons. So the entire universe is made out of particles. Now what are the particles made out of They're not made out of anything. The only thing you can say about the reality of an electron is to cite its mathematical properties. So there's a sense in which matter has completely dissolved and what is left is just a mathematical structure.”

“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.”

“Toward the end of the Cold War, capitalism created a military horror: the neutron bomb, a weapon that destroys life while leaving buildings intact. During the Fourth World War, however, a new wonder has been discovered: the financial bomb. Unlike those dropped on Hiroshima and Nagasaki, this new bomb not only destroys the polis (here, the nation), imposing death, terror, and misery on those who live there, but also transforms its target into just another piece in the puzzle of economic globalization.”

“With what moral authority can they speak of human rights - the rulers of a nation in which the millionaire and beggar coexist; the Indian is exterminated; the black man is discriminated against; the woman is prostituted; and the great masses of Chicanos, Puerto Ricans, and Latin Americans are scorned, exploited, and humiliated? How can they do this - the bosses of an empire where the mafia, gambling, and child prostitution are imposed; where the CIA organizes plans of global subversion and espionage, and the Pentagon creates neutron bombs capable of preserving material assets and wiping out human beings.”
