I believe that a scientist looking at nonscientific problems is just as dumb as the next guy. Book by Richard P. Feynman, 1988. Study hard what interests you the most in the most undisciplined, irreverent and original manner possible. In that simple statement is the key to science. If it doesn’t agree with experiment, it’s wrong. You can recognize truth by its beauty and simplicity. If it disagrees with experience, the guess is wrong. From a long view of the history of mankind—seen from, say, ten thousand years from now—there can be little doubt that the most significant event of the 19th century will be judged as Maxwell’s discovery of the laws of electrodynamics. 2 (1965), Richard P. Feynman (2014). ", I learned a lot of different things from different schools. the most important discovery in the history of the theory of quantum electrodynamics. I can live with doubt and uncertainty. We don't just see light. God is always associated with those things that you do not understand. The fact that I beat a drum has nothing to do with the fact that I do theoretical physics. From interview by BBC TV in episode 'The Pleasure of Finding Things Out'. It is a good guess. God was invented to explain mystery. This is not yet a scientific age. Interview, in BBC TV program, 'The Pleasure of Finding Things Out', I learned a lot of different things from different schools. What is the pattern, or the meaning, or the “why?” It does not do harm to the mystery to know a little about it. However, one of his greatest characteristics was his ability to transmit the knowledge he had to others in a way they could grasp. The imagination of nature is far, far greater than the imagination of man. Upon identifying the reason for the explosion of the space shuttle. Richard P. Feynman > Quotes > Quotable Quote “We absolutely must leave room for doubt or there is no progress and there is no learning. 'Probability abd Uncertainty—the Quantum Mechanical View of Nature', the sixth of his Messenger Lectures (1964), Cornell University. Turbulence is the most important unsolved problem of classical physics. We measure “disorder” by the number of ways that the insides can be arranged, so that from the outside it looks the same. Richard Feynman was one of the great scientists and physicists of our time, truly one of the great minds of humanity. From Commencement Address, Caltech (1974), 'Cargo Cult Science'. In 'The Law of Gravitation, as Example of Physical Law', the first of his Messenger Lectures (1964), Cornell University. Collected in. “Perfectly Reasonable Deviations from the Beaten Track: The Letters of Richard P. Feynman”, p.256, Hachette UK, The Character of Physical Law ch. I don’t like that they’re not calculating anything. 2, February 1989. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on. Principles. But the most impressive fact is that gravity is simple…. Principles. “Half genius and half buffoon,” Freeman Dyson ... wrote. It is simple, and therefore it is beautiful…. The whole question of imagination in science is often misunderstood by people in other disciplines. It doesn’t frighten me. In interview for the American Association for the Advancement of Science (AAAS), 'Richard Feynman Builds a Universe', collected in Jeffrey Robbins (ed.). First you guess. I think equation guessing might be the best method to proceed to obtain the laws for the part of physics which is presently unknown. -- Richard P. Feynman . I do not know. It has developed for itself a spirit, so that every member of the whole place thinks that it’s the most wonderful place in the world—it’s the center, somehow, of scientific and technological development in the United States, if not the world … and while you don’t get a good sense of proportion there, you do get an excellent sense of being with it and in it, and having motivation and desire to keep on. These are beautiful things, and the content of science is wonderfully full of them. When they are burned, they go back to air, and in the flaming heat is released the flaming heat of the sun which was bound in to convert the air into tree, and in the ash is the small remnant of the part which did not come from air, that came from the solid earth, instead. Then new students should as a class have this. Feynman’s last words… I’d hate to die twice. A good theoretical physicist today might find it useful to have a wide range of physical viewpoints and mathematical expressions of the same theory (for example, of quantum electrodynamics) available to him. Noted in his pocket address book. There is one simplification at least. Davies and J. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" I have approximate answers and possible beliefs in different degrees of certainty about different things, but I am not absolutely sure of anything, and of many things I don’t know anything about but I don’t have to know an answer. But there are tens of thousands of years in the future. Suppose we divide the space into little volume elements. Published in. Tell your son to stop trying to fill your head with science—for to fill your heart with love is enough. This may be asking too much of one man. Now, when you finally discover how something works … you don't need him anymore. Mathematics may be applied in the complex situation to figure out what in given circumstances is a good move to make. Collected in Stig Lundqvist. The problem is clear language. A philosopher once said, ‘It is necessary for the very existence of science that the same conditions always produce the same results’. You see my physics students don't understand it... That is because I don't understand it. You can’t say A is made of B or vice versa. As stated in Lee Dye, 'Nobel Physicist R.P. Second, it is not exact; Einstein had to modify it…. … I find that teaching and the students keep life going, and I would never accept any position in which somebody has invented a happy situation for me where I don’t have to teach. Quoted in P. C. W. Davies and Julian Brown (eds.). © 2020 Richard Feynman. Well, they don’t! Clearly, there are many more ways to arrange them in the latter case. The idea that time may vary from place to place is a difficult one, but it is the idea Einstein used, and it is correct—believe it or not. The inexperienced, the crackpots, and people like that, make guesses that are simple, but you can immediately see that they are wrong, so that does not count. The usual theoretical physics was done since the time of Newton was to begin by writing down some equations and then to work hard calculating solutions of the equations.
