"Suppose Germany had developed two bombs before we had any bombs. And suppose Germany had dropped one bomb, say, on Rochester and the other on Buffalo, and then having run out of bombs she would have lost the war. Can anyone doubt that we would then have defined the dropping of atomic bombs on cities as a war crime, and that we would have sentenced the Germans who were guilty of this crime to death at Nuremberg and hanged them? But, again, don't misunderstand me. The only conclusion we can draw is that governments acting in a crisis are guided by questions of expediency, and moral considerations are given very little weight, and that America is no different from any other nation in this respect."
"A great power imposes the obligation of exercising restraint, and we did not live up to this obligation. I think this affected many of the scientists in a subtle sense, and it diminished their desire to continue to work on the bomb."
"If we focus our attention on the next twenty-five years we may say that development is likely to reach some point intermediate between the first bomb detonated over Hiroshima and processes which once initiated might put an end to all life on earth. Just what intermediate point will be reached within twenty-five years no one can tell."
"I'm looking for a market for wisdom."
"A scientist's aim in a discussion with his colleagues is not to persuade, but to clarify."
"The most important step in getting a job done is the recognition of the problem. Once I recognize a problem I usually can think of someone who can work it out better than I could."
"In order to succeed it is not necessary to be much cleverer than other people. All you have to do is be one day ahead of them."
"It is not necessary to succeed in order to persevere. As long as there is a margin of hope, however narrow, we have no choice but to base all our actions on that margin. America and Russia have one interest in common which may override all their other interests: to be able to live with the bomb without getting into an all-out war that neither of them wants."
"In life you must often choose between getting a job done or getting credit for it. In science, the most important thing is not the ideas you have but the decision which ones you choose to pursue. If you have an idea and are not doing anything with it, why spoil someone else's fun by publishing it?"
"Science is progressing at such a rapid rate that when you make a prediction and think you are ahead of your time by 100 years you may be ahead of your time by 10 at most."
"All we had to do was lean back, turn a switch and watch a screen of a television tube. If flashes of light appeared on the screen it would mean that liberation of atomic energy would take place in our lifetime. We turned the switch, saw the flashes — we watched for about five minutes — then switched everything off and went home. That night I knew the world was headed for trouble."
"A man's clarity of judgment is never very good when you're involved, and as you grow older, and as you grow more involved, your clarity of judgment suffers."
"Even if we accept, as the basic tenet of true democracy, that one moron is equal to one genius, is it necessary to go a further step and hold that two morons are better than one genius?"
"I sometimes have the feeling that I have lived through all this before and, in a sense, I have. I was sixteen years old when the first World War broke out, and I lived at that time in Hungary. From reading the newspapers in Hungary, it would have appeared that, whatever Austria and Germany did was right and whatever England, France, Russia, or America did was wrong. A good case could be made out for this general thesis, in almost every single instance. It would have been difficult for me to prove, in any single instance, that the newspapers were wrong, but somehow, it seemed to me unlikely that the two nations located in the center of Europe should be invariably right, and that all the other nations should be invariably wrong. History, I reasoned, would hardly operate in such a peculiar fashion, and it didn't take long until I began to hold views which were diametrically opposed to those held by the majority of my schoolmates."
"Even in times of war, you can see current events in their historical perspective, provided that your passion for the truth prevails over your bias in favor of your own nation."
"The people who have sufficient passion for the truth to give the truth a chance to prevail, if it runs counter to their bias, are in a minority. How important is this "minority?" It is difficult to say at this point, for, at the present time their influence on governmental decisions is not perceptible."
"I had not been long back from Hiroshima when I heard someone say, in Szilárd's presence; that it was the tragedy of scientists that their discoveries were used for destruction. Szilárd replied, as he more than anyone else had the right to reply; that it was not the tragedy of scientists, it is the tragedy of mankind."
"By the time his ideas became accepted he had already forged ahead to take up a new attitude. Szilard himself illustrated this characteristic in a story which he liked to tell about himself. He served once on a jury in a murder case. When the first vote was taken, eleven jurors were in favour of convicting, but one — Szilard — was for acquittal. Since unanimity was required, the discussion was resumed and Szilard expounded his arguments. After some time another vote was taken; the result was again eleven to one, but this time eleven were for acquittal, and one for conviction: the odd vote was Szilard’s who had in the meantime changed his mind!"
"After the war ended, partly disgusted by the cruel use to which his beloved physics had been put, Szilard left professional physics to explore new pastures – in his case, biology... there was a more pragmatic reason. As Szilard put it, this was an age when you took a year to discover something new in physics but only took a day to discover something new in biology."
"Another explanation for the failure of logic and observation alone to advance medicine is that unlike, say, politics, which uses a form of logic – mathematics – as its natural language, biology does not lend itself to logic. Leo Szilard, a prominent physicist, made this point when he complained that after switching from physics to biology he never had a peaceful bath again. As a physicist he would soak in the warmth of the bathtub and contemplate a problem, turn it in his mind, reason his way through it. But once he became a biologist, he constantly had to climb out of the bathtub to look up a fact."
"I think it is a sad reflection on our civilisation that while we can and do measure the temperature in the atmosphere of Venus, we do not know what goes on inside our souffles."
"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."
"Two paradoxes are better than one; they may even suggest a solution."
"Physics is, hopefully, simple. Physicists are not."
"No, I'm the infamous Edward Teller."
"We must learn to live with contradictions, because they lead to deeper and more effective understanding."
"Religion was not an issue in my family; indeed, it was never discussed. My only religious training came because the Minta required that all students take classes in their respective religions. My family celebrated one holiday, the Day of Atonement, when we all fasted. Yet my father said prayers for his parents on Saturdays and on all the Jewish holidays. The idea of God that I absorbed was that it would be wonderful if He existed: We needed Him desperately but had not seen Him in many thousands of years."
"I contributed; Ulam did not. I'm sorry I had to answer it in this abrupt way. Ulam was rightly dissatisfied with an old approach. He came to me with a part of an idea which I already had worked out and difficulty getting people to listen to. He was willing to sign a paper. When it then came to defending that paper and really putting work into it, he refused. He said, "I don't believe in it.""
"My name is not Strangelove. I don't know about Strangelove. I'm not interested in Strangelove. What else can I say?... Look. Say it three times more, and I throw you out of this office."
"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 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."
"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.""
"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."
"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."
"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."
"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."
"Where in the Schrödinger equation do you put the joy of being alive?"
"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."
"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."
"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."
"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."
"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."
"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."
"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."
"...the ultimate objective of teaching physics is promoting a sound physical thinking and not merely tackling a list of topics."
"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."
"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."
"The trouble with theorists is, they never pay attention to the experiments!"
"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."
