101 " Never be ashamed of madness, instead be ashamed of people that are ashamed of madness. Without a little bit of insanity, we would have never had the Theory of Relativity, electricity, airplanes, cars or your beloved iPhone. Madness got you that. "
― Shannon L. Alder
102 " At school we learn the theory to do the practice, but they didn't teach you that in real life you learn from the practice to know the theory "
103 " The theories of the social sciences do not consist of “laws” in the sense of empirical rules about the behavior of objects definable in physical terms. All that the theory of the social sciences attempts is to provide a technique of reasoning which assists us in connecting individual facts, but which, like logic or mathematics, is not about the facts. It can, therefore, and this is the second point, never be verified or falsified by reference to facts. "

104 " Neoclassical economics is precisely the theory one would expect a vastly complex system of international corporations, world markets, and interconnected currencies to create to sustain, justify, explain, and predict " itself." And classical economics, correspondingly, was a predictable expression of an earlier European capitalism. "
105 " Entrepreneurship rests on a theory of economy and society. The theory sees change as normal and indeed as healthy. And it sees the major task in society - and especially in the economy - as doing something different rather than doing better what is already being done. That is basically what Say, two hundred years ago, meant when he coined the term entrepreneur. It was intended as a manifesto and as a declaration of dissent: the entrepreneur upsets and disorganizes. As Joseph Schumpeter formulated it, his task is " creative destruction. "
106 " It is a small world. You do not have to live in it particuarly long to learn that for yourself. There is a theory that, in the whole world, there are only five hundred real people (the cast, as it were; all the rest of the people in the world, the theory suggests, are extras) and what is more, they all know each other. In reality the world is made of thousands upon thousands of groups of about five hundred people, all of whom will spend their lives bumping into each other, trying to avoid each other, and discovering each other in the same unlikely teashop in Vancouver. There is an unavoidability to this process. It's not even coincidence. It's just the way the world works, with no regard for individuals or for propriety. "

107 " I'm afraid Dr. Mondrick chose an unfortunate publicity device. After all, the theory of human evolution is no longer front page news. Every known detail of the origin of mankind is extremely important to such a specialist as Dr. Mondrick, but it doesn't interest the man in the street - not unless it's dramatized. "

108 " From a book you can learn the theory but it takes practise to learn how to live life. "

109 " The public never appears to tire of endless courses of strawberries and cream, and the theory that you run the risk of boring people with endless photo montages of the Chelsea Pensioners in their dress reds, or close-ups of a Pimm's Cup sprouting all kinda of flora, has yet to be proven. People like Wimbledon in the same way they like blue jeans or even their own spouses: for the pleasure yielded by their reliable sameness. "

110 " Everything must be taken into account. If the fact will not fit the theory---let the theory go. "

111 " Some persons fancy that bias and counter-bias are favorable to the extraction of truth–that hot and partisan debate is the way to investigate. This is the theory of our atrocious legal procedure. But Logic puts its heel upon this suggestion. It irrefragably demonstrates that knowledge can only be furthered by the real desire for it, and that the methods of obstinacy, of authority and every mode of trying to reach a foregone conclusion, are absolutely of no value. These things are proved. The reader is at liberty to think so or not as long as the proof is not set forth, or as long as he refrains from examining it. Just so, he can preserve, if he likes, his freedom of opinion in regard to the propositions of geometry; only, in that case, if he takes a fancy to read Euclid, he will do well to skip whatever he finds with A, B, C, etc., for, if he reads attentively that disagreeable matter, the freedom of his opinion about geometry may unhappily be lost forever. "

112 " I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according to well understood logical rules, step by step, a stately edifice, while his imaginative power brings out clearly the hidden relations between its parts. A well constructed theory is in some respects undoubtedly an artistic production. A fine example is the famous Kinetic Theory of Maxwell. ... The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art. "
― Ernest Rutherford
113 " Get it? Gender is a country, a field of signifying roses you can walk through, or wear tucked behind your ear.Eventually the flower wilts & you can pick another, or burn the field, or turn & run back across the tracks.(from " Essay on the Theory of Motion" ) "
114 " you're Shane, right?'He inched away from her and managed a quick nod as he twisted the rag he held in his fingers. 'Heidi sad you were willing to teach me how to ride.' Her expression shifted from entertained to confused, as if she was wondering why no one had mentioned he was a can or two shy of a six-pack. 'A horse,' he clarified, then wanted to kick himself. What else but a horse? Did he think she was here to learn to ride his mother's elephant? One corner of Annabelle's perfect, full mouth twitched. 'A horse would be good. You seem to have several.'He wanted to remind himself that he was usually fine around women. Smooth even. He was intelligent, funny and could, on occasion, be charming. Just not now, with his blood pumping and his brain doing nothing more than shouting " it's her, it's her" over and over again. Chemistry, he thought grimly. It could turn the smartest man into a drooling idiot. Here he was, proving the theory true. "
115 " [The] structural theory is of extreme simplicity. It assumes that the molecule is held together by links between one atom and the next: that every kind of atom can form a definite small number of such links: that these can be single, double or triple: that the groups may take up any position possible by rotation round the line of a single but not round that of a double link: finally that with all the elements of the first short period [of the periodic table], and with many others as well, the angles between the valencies are approximately those formed by joining the centre of a regular tetrahedron to its angular points. No assumption whatever is made as to the mechanism of the linkage. Through the whole development of organic chemistry this theory has always proved capable of providing a different structure for every different compound that can be isolated. Among the hundreds of thousands of known substances, there are never more isomeric forms than the theory permits. "
― Nevil Vincent Sidgwick
116 " We have one real candidate for changing the rules; this is string theory. In string theory the one-dimensional trajectory of a particle in spacetime is replaced by a two-dimensional orbit of a string. Such strings can be of any size, but under ordinary circumstances they are quite tiny, ... a value determined by comparing the predictions of the theory for Newton's constant and the fine structure constant to experimental values. "
― Edward Witten
117 " Realizing its fundamental importance in understanding spectral lines, in atomic physics and in the theory of how light and electrons interact, quantum electrodynamics, Pauli and Heisenberg were determined to derive it from quantum theory rather than introducing it from the start. They believed that if they could find a version of quantum electrodynamics capable of producing the fine structure constant, it would not contain the infinities that marred their theories. "

118 " Electrons, when they were first discovered, behaved exactly like particles or bullets, very simply. Further research showed, from electron diffraction experiments for example, that they behaved like waves. As time went on there was a growing confusion about how these things really behaved ---- waves or particles, particles or waves? Everything looked like both.This growing confusion was resolved in 1925 or 1926 with the advent of the correct equations for quantum mechanics. Now we know how the electrons and light behave. But what can I call it? If I say they behave like particles I give the wrong impression; also if I say they behave like waves. They behave in their own inimitable way, which technically could be called a quantum mechanical way. They behave in a way that is like nothing that you have seen before. Your experience with things that you have seen before is incomplete. The behavior of things on a very tiny scale is simply different. An atom does not behave like a weight hanging on a spring and oscillating. Nor does it behave like a miniature representation of the solar system with little planets going around in orbits. Nor does it appear to be somewhat like a cloud or fog of some sort surrounding the nucleus. It behaves like nothing you have seen before.There is one simplication at least. Electrons behave in this respect in exactly the same way as photons; they are both screwy, but in exactly in the same way….The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, " But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. I will not describe it in terms of an analogy with something familiar; I will simply describe it. There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time. There might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot of people understood the theory of relativity in some way or other, certainly more than twelve. On the other hand, I think I can safely say that nobody understands quantum mechanics. So do not take the lecture too seriously, feeling that you really have to understand in terms of some model what I am going to describe, but just relax and enjoy it. I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, " But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that. "
119 " The great object is to find the theory of the matter [of X-rays] before anyone else, for nearly every professor in Europe is now on the warpath. "
120 " After the discovery of spectral analysis no one trained in physics could doubt the problem of the atom would be solved when physicists had learned to understand the language of spectra. So manifold was the enormous amount of material that has been accumulated in sixty years of spectroscopic research that it seemed at first beyond the possibility of disentanglement. An almost greater enlightenment has resulted from the seven years of Röntgen spectroscopy, inasmuch as it has attacked the problem of the atom at its very root, and illuminates the interior. What we are nowadays hearing of the language of spectra is a true 'music of the spheres' in order and harmony that becomes ever more perfect in spite of the manifold variety. The theory of spectral lines will bear the name of Bohr for all time. But yet another name will be permanently associated with it, that of Planck. All integral laws of spectral lines and of atomic theory spring originally from the quantum theory. It is the mysterious organon on which Nature plays her music of the spectra, and according to the rhythm of which she regulates the structure of the atoms and nuclei. "
