Physicists From Hungary

"Reports of the death of reductionism are greatly exaggerated. It is so ingrained in our thinking that if one day some magical force should make us all forget it, we would promptly have to reinvent it. The real worry is not with reductionism, which, as a paradigm and tool, is rather useful. It is necessary, but no longer sufficient. But, weighing up better ideas, it became a burden."

"The trouble with theorists is, they never pay attention to the experiments!"

"What is very important to me is two points: A theory should be internally consistent and it should have some contact with observation. Well, I’m told by all the experts that this theory String theory] is internally consistent, although they think up new interpretations every time I turn my back. But contact with reality? Nobody’s given me anything. I just watch. I’m somewhat unhappy that so many people are working on it. To me, as a physicist, it’s sort of sad that so many people at the same time work at something that doesn’t seem to have any contact with experiment. But that, to some extent, is due to the fact that we don’t have any great experimental puzzle to be thinking about. We have to supply the puzzles, and there aren’t that many puzzles right now."

"Feynman was not a theorist's theorist, but a physicist's physicist and a teacher's teacher. Feynman's theoretical concepts opened up research opportunities for experimenters, and his approach to physics dignified the role played by their work."

"...the ultimate objective of teaching physics is promoting a sound physical thinking and not merely tackling a list of topics."

"If history has a lesson, it is that the "winner take all" attitude deprives one of the pleasures of being the heir to the best of different traditions, even while avoiding their intolerance against each other."

"If we want to make a discovery, we have to take a risk, since everything new was discovered by accident or by the fact that somebody took a chance and went ahead when there wasn't 100 percent safety for the solution."

"It is not the things that we have, but how we use them that is important."

"Too much equipment can be, however, something that hampers scientific development. I had the feeling that if there is no equipment present, everybody is forced to simplify his ideas in such a way that the experiments become simple. If there is too much equipment available, he can attack any experiment immediately since all the difficulties will be overcome by putting more money in the equipment. In the long run, some of the equipment becomes so complicated that it is difficult to see how all the parts interact."

"I do not know of anything in modern poetry as violently hostile to contemporary life as was the poetry of T. S. Eliot, which so perfectly fitted the mood of the young people between the two wars. I also find much more benevolence towards humanity in younger historians than there was in Spengler or in Toynbee. Still, it is not difficult to sense the disgust of the intellectuals at the new prosperous working class, 'with their eyes glued to the television screen,' who have become indifferent to radical ideas."

"The future cannot be predicted, but futures can be invented. It was man's ability to invent which has made human society what it is."

"It would be pleasant to believe that the age of pessimism is now coming to a close, and that its end is marked by the same author who marked its beginning: Aldous Huxley. After thirty years of trying to find salvation in mysticism, and assimilating the Wisdom of the East, Huxley published in 1962 a new constructive utopia, The Island. In this beautiful book he created a grand synthesis between the science of the West and the Wisdom of the East, with the same exceptional intellectual power which he displayed in his Brave New World. (His gaminerie is also unimpaired; his close union of eschatology and scatology will not be to everybody's tastes.) But though his Utopia is constructive, it is not optimistic; in the end his island Utopia is destroyed by the sort of adolescent gangster nationalism which he knows so well, and describes only too convincingly. This, in a nutshell, is the history of thought about the future since Victorian days. To sum up the situation, the sceptics and the pessimists have taken man into account as a whole; the optimists only as a producer and consumer of goods. The means of destruction have developed pari passu with the technology of production, while creative imagination has not kept pace with either. The creative imagination I am talking of works on two levels. The first is the level of social engineering, the second is the level of vision. In my view both have lagged behind technology, especially in the highly advanced Western countries, and both constitute dangers."

"Incomplete knowledge of the future, and also of the past of the transmitter from which the future might be constructed, is at the very basis of the concept of information. On the other hand, complete ignorance also precludes communication; a common language is required, that is to say an agreement between the transmitter and the receiver regarding the elements used in the communication process... [The information of a message can] be defined as the 'minimum number of binary decisions which enable the receiver to construct the message, on the basis of the data already available to him.' These data comprise both the convention regarding the symbols and the language used, and the knowledge available at the moment when the message started."

"A possible explanation of the physicist's use of mathematics to formulate his laws of nature is that he is a somewhat irresponsible person. As a result, when he finds a connection between two quantities which resembles a connection well-known from mathematics, he will jump at the conclusion that the connection is that discussed in mathematics simply because he does not know of any other similar connection."

"Where in the Schrödinger equation do you put the joy of being alive?"

"In science, it is not speed that is the most important. It is the dedication, the commitment, the interest and the will to know something and to understand it — these are the things that come first."

"The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve."

"A deep sense of humor and an unusual ability for telling stories and jokes endeared Johnny even to casual acquaintances. He could be blunt when necessary, but was never pompous. A mind of von Neumann's inexorable logic had to understand and accept much that most of us do not want to accept and do not even wish to understand. This fact colored many of von Neumann's moral judgments. "It is just as foolish to complain that people are selfish and treacherous as it is to complain that the magnetic field does not increase unless the electric field has a curl. Both are laws of nature." Only scientific intellectual dishonesty and misappropriation of scientific results could rouse his indignation and ire — but these did — and did almost equally whether he himself, or someone else, was wronged."

"I believe in excellence. It is a basic need of every human soul. All of us can be excellent, because, fortunately, we are exceedingly diverse in our ambitions and talents."

"The eyes of childhood are magnifying lenses."

"When you fight for a desperate cause and have good reasons to fight, you usually win."

"At the end of the war, most people wanted to stop. I didn't. Because here was more knowledge. And in the coming uncertain period, with a dangerous man like Stalin around, and our incomplete knowledge, I felt that more knowledge is necessary. Among the people who knew a great deal about the hydrogen bomb, I was the only advocate of it. And that is, I think, my contribution. Not that I invented it, others would have — and others in the Soviet Union did. But I was the one person who put knowledge, and the availability of knowledge, above everything else."

"There is no case where ignorance should be preferred to knowledge — especially if the knowledge is terrible."

"Secrecy in science does not work. Withholding information does more damage to us than to our competitors."

"When you come to the end of all the light you know, and it's time to step into the darkness of the unknown, faith is knowing that one of two things shall happen: either you will be given something solid to stand on or you will be taught to fly."

"If we could have ended the war by showing the power of science without killing a single person, all of us would now be happier, more reasonable and much more safe."

"I hate doubt, yet I am certain that doubt is the only way to approach anything worth believing in."

"I believe in good. It is an ephemeral and elusive quality. It is the center of my beliefs, but it cannot be strengthened by talking about it."

"I believe in evil. It is the property of all those who are certain of truth. Despair and fanaticism are only differing manifestations of evil."

"I believe that no endeavor that is worthwhile is simple in prospect; if it is right, it will be simple in retrospect."

"A stands for atom; it is so small No one has ever seen it at all. B stands for bombs; the bombs are much bigger. So, brother, do not be too fast on the trigger. F stands for fission; that is what things do When they get wobbly and big and must split in two. And just to confound the atomic confusion What fission has done may be undone by fusion. H has become a most ominous letter; It means something bigger, if not something better. S stands for secret; you can keep it forever — Provided there's no one abroad who is clever."

"(Are there any scientists who may be well known, but who repulse you?) IA: Oh, sure. Edward Teller. I mean, there's my idea of a scientific villain."

"Business institutions universities Both are quite the circus where the killer wants his way I think of Edward Teller and his moribund reprise Then I look to Nevada and I can't believe my eyes It's time for him to die!"

"Dr. Teller has a mind very different from mine. I think one needs both kinds of minds to make a successful project. I think Dr. Teller's mind runs particularly to making brilliant inventions, but what he needs is some control, some other person who is more able to find out just what is the scientific fact about the matter. Some other person who weeds out the bad from the good ideas."

"Teller's mistake was his failure to foresee that a large section of the public would not consider his appearance at the Oppenheimer hearing to be decent behavior. Had Teller not appeared, the outcome of the hearing would almost certainly have been unaffected, and the moral force of Teller's position would not have been tainted."

"Before Bethe married, he was so often a guest in the Teller home that he became almost one of the family. In April, 1954, that was all over. There could be no real reconciliation. Bethe had lost one of his oldest friends. But Teller had lost more. Teller, by lending his voice to the cause of Oppenheimer's enemies, had lost not only the friendship but the respect of many of his colleagues, and he was portrayed by newspaper writers and cartoonists as a Judas, a man who had betrayed his leader for the sake of personal gain."

"When we came back through the trees to the house, we heared a strange sound coming through the open door. The children stopped their chatter and we all stood outside the door and listened. It was my old friend from long ago, Bach's Prelude No. 8 in E-flat minor. Superbly played. Played just the way my father used to play it. For a moment I was completely disoriented. I thought: What the devil is my father doing here in California? We stood in front of our Berkeley house and listened to that prelude. Whoever was playing it was putting into it his whole heart and soul. The sound floated up to us like a chorus of mourning from the depths, as if the spirits in the underworld were dancing to a slow pavane. We waited until the music came to an end and then walked in. There, sitting at the piano, was Edward Teller. We asked him to go on playing, but he excused himself."

"The physicist Edward Teller, known as the “father of the H-bomb,” went further to deny that omnicide—a concept he derided—was remotely feasible. In answer to a question I posed to him as late as 1982, he said emphatically it was “impossible” to kill by any imaginable use of thermonuclear weapons that he had co-invented “more than a quarter of the earth’s population.” At the time, I thought of this assurance, ironically, as his perception of “the glass being three-quarters full.” (Teller was, along with Kahn, Henry Kissinger, and the former Nazi missile designer Wernher von Braun, one of Kubrick’s inspirations for the character of Dr. Strangelove.) And Teller’s estimate was closely in line with what the JCS actually planned to do in 1961, though a better estimate (allowing for the direct effects of fire, which JSC calculations have always omitted) would have been closer to one-third to one-half of total omnicide. But the JCS were mistaken in 1961, and so was Herman Kahn in 1960, and so was Teller in 1982. Nobody’s perfect. Just one year after Teller had made this negative assertion (at a hearing of the California state legislature which we both addressed, on the Bilateral Nuclear Weapons Freeze Initiative), the first papers appeared on the nuclear-winter effects of smoke injected into the stratosphere by firestorms generated by a thousand or more of the fifty thousand existing H-bombs used on cities. Contrary to Kahn and Teller, an American Doomsday Machine already existed in 1961—and had for years—in the form of pre-targeted bombers on alert in the Strategic Air Command (SAC), soon to be joined by Polaris submarine-launched missiles. Although this machine wasn’t likely to kill outright or starve to death literally every last human, its effects, once triggered, would come close enough to that to deserve the name Doomsday."

"He is a danger to all that is important. I do really feel it would have been a better world without Teller."

"After he suffered a stroke three years ago, a nurse quizzed him to probe his lucidity. "Are you the famous Edward Teller?" she queried. "No," he snapped. "I'm the infamous Edward Teller.""

"It is not even impossible to imagine that the effects of an atomic war fought with greatly perfected weapons and pushed by the utmost determination will endanger the survival of man."

"If we stay strong, then I believe we can stabilize the world and have peace based on force. Now, peace based on force is not as good as peace based on agreement, but in the terrible world in which we live, in the world where the Russians have enslaved many millions of human beings, in the world where they have killed men, I think that for the time being the only peace we can have is the peace based on force. Furthermore, I do not think that this peace based on force is, can be, or should be, an ultimate end. Our ultimate end must be precisely what Dr. Pauling says, peace based on agreement, on understanding, on universally agreed and enforced law. I think this is a wonderful idea, but peace based on force buys the necessary time, and in this time we can work for better understanding, for closer collaboration, first with the countries which are closest to us, which we understand better, our allies, the western countries, the NATO countries, which believe in human liberties as we do. Then, as soon as possible, with the rest of the free world, and eventually, I hope, with the whole world, including Russia, even though it may take many years to come."

"I don't want to kill anybody. I am passionately opposed to killing, but I'm even more passionately fond of freedom. The freedom of Dr. Pauling and of myself expressing our opinions freely on any subject, however broad, however far removed of our proper competence, but particularly, to be able to express our opinions in the fields we really know; this would not be possible in Russia."

"Ladies and gentlemen, I am to talk to you about energy in the future. I will start by telling you why I believe that the energy resources of the past must be supplemented. First of all, these energy resources will run short as we use more and more of the fossil fuels. But I would [...] like to mention another reason why we probably have to look for additional fuel supplies. And this, strangely, is the question of contaminating the atmosphere. [....] Whenever you burn conventional fuel, you create carbon dioxide. [....] The carbon dioxide is invisible, it is transparent, you can’t smell it, it is not dangerous to health, so why should one worry about it? Carbon dioxide has a strange property. It transmits visible light but it absorbs the infrared radiation which is emitted from the earth. Its presence in the atmosphere causes a greenhouse effect [....] It has been calculated that a temperature rise corresponding to a 10 per cent increase in carbon dioxide will be sufficient to melt the icecap and submerge New York. All the coastal cities would be covered, and since a considerable percentage of the human race lives in coastal regions, I think that this chemical contamination is more serious than most people tend to believe."

"At present the carbon dioxide in the atmosphere has risen by 2 per cent over normal. By 1970, it will be perhaps 4 per cent, by 1980, 8 per cent, by 1990, 16 per cent [about 360 parts per million, by Teller’s accounting], if we keep on with our exponential rise in the use of purely conventional fuels. By that time, there will be a serious additional impediment for the radiation leaving the earth. Our planet will get a little warmer. It is hard to say whether it will be 2 degrees Fahrenheit or only one or 5. But when the temperature does rise by a few degrees over the whole globe, there is a possibility that the icecaps will start melting and the level of the oceans will begin to rise. Well, I don’t know whether they will cover the Empire State Building or not, but anyone can calculate it by looking at the map and noting that the icecaps over Greenland and over Antarctica are perhaps five thousand feet thick."

"On May 7, a few weeks after the accident at Three-Mile Island, I was in Washington. I was there to refute some of that propaganda that Ralph Nader, Jane Fonda and their kind are spewing to the news media in their attempt to frighten people away from nuclear power. I am 71 years old, and I was working 20 hours a day. The strain was too much. The next day, I suffered a heart attack. You might say that I was the only one whose health was affected by that reactor near Harrisburg. No, that would be wrong. It was not the reactor. It was Jane Fonda. Reactors are not dangerous."

"By having simplified what is known, physicists have been led into realms which as yet are anything but simple. That at some time, they, too, will appear as simple consequences of a theory of which no one has yet dreamed is not a statement of fact. It is a statement of faith."

"The preservation of peace and the improvement of the lot of all people require us to have faith in the rationality of humans. If we have this faith and if we pursue understanding, we have not the promise but at least the possibility of success. We should not be misled by promises. Humanity in all its history has repeatedly escaped disaster by a hair's breadth. Total security has never been available to anyone. To expect it is unrealistic; to imagine that it can exist is to invite disaster. What we do have in our technological capacities is an opportunity to use our inventiveness, our creativity, our wisdom and our understanding of our fellow beings to create a future world that is a little better than the one in which we live today."

"There's no system foolproof enough to defeat a sufficiently great fool."

"A fact is a simple statement that everyone believes. It is innocent, unless found guilty. A hypothesis is a novel suggestion that no one wants to believe. It is guilty, until found effective."
