It need not exist in a theory.” – Richard P. Feynman, “The ideas associated with the problems of the development of science, as far as I can see by looking around me, are not of the kind that everyone appreciates.” – Richard P. Feynman, “You have no responsibility to live up to what other people think you ought to accomplish. The second amazing thing about gravitation is how weak it is.” – Richard P. Feynman, “We seem gradually to be groping toward an understanding of the world of subatomic particles, but we really do not know how far we have yet to go in this task.” – Richard P. Feynman, “I got a signed document from Bullock’s saying that they had such-and-such drawings on consignment. Discover Richard P. Feynman famous and rare quotes. And yet it fully agrees with experiment. “If you think you understand quantum mechanics, you don't understand quantum mechanics.” “If you think you understand quantum mechanic Richard Feynman, the late Nobel Laureate in physics, was once asked by a Caltech faculty member to explain why spin one-half particles obey Fermi Dirac statistics. “I think I can safely say that nobody understands quantum mechanics.” It is one of the most repeated quotes of Richard Feynman (11 May 1918 – 15 February 1988), and is undoubtedly an unusual phrase coming from the mouth of a physicist. Want another Slice of PI? Born on 11 May 1918 in New York, New York, United States, Richard Phillips Feynman was a theoretical physicist who was famous for his theory on quantum electrodynamics. Help yourself: Learn Particle Physics in 30 Seconds; Happy Birthday to “The Father of Quantum Theory” PI Day However, I didn’t want people to buy my drawings because the professor of physics isn’t supposed to be able to draw – isn’t that wonderful – so I made up a false name.” – Richard P. Feynman, “The idea is to try to give all the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another.” – Richard P. Feynman, “Perhaps one day we will have machines that can cope with approximate task descriptions, but in the meantime, we have to be very prissy about how we tell computers to do things.” – Richard P. Feynman, “I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value to realize that we do not know the answers to different questions. Even though it was discovered by physicists, it’s not a physical theory in the same sense as electromagnetism or general relativity. "Science is the belief in the ignorance of..." Login Sign Up. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. There are 10^11 stars in the galaxy. “We absolutely must leave room for doubt or there is no progress and no learning. If it doesn’t agree with experiment, it’s wrong.” – Richard P. Feynman, “The situation in the sciences is this: A concept or an idea which cannot be measured or cannot be referred directly to experiment may or may not be useful. See more ideas about richard feynman, richard feynman quotes, richard. Originally Answered: Richard Feynman said that, “I think I can safely say that nobody understands quantum mechanics." I think a power to do something is of value. For contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin’ichirō Tomonaga. The notable thing about this book is that it is fairly accessible for non-physicists – much more than most other quantum physics books. One of the most famous scientists of the twentieth century, and an inexhaustible source of wonderful quotes, Richard Feynman shared the 1965 Nobel Prize in Physics with Julian Schwinger and Sin-Itiro Tomonaga for his contributions to the development of quantum electrodynamics. I, too, can see the stars on a desert night, and feel them. But I don’t have to know an answer. One had to lose one’s common sense in order to perceive what was happening at the atomic level.” – Richard P. Feynman, “I think it’s much more interesting to live not knowing than to have answers which might be wrong. If you’re finding quantum theory hard to swallow, ... Richard Feynman ... Quantum mechanics is a probabilistic theory: it does not give definite answers, but only the probability that an experiment will come up with a particular answer. ...Nobody knows how it can be like that.” eval(ez_write_tag([[300,250],'inspiringquotes_us-box-4','ezslot_0',125,'0','0'])); “Unless a thing can be defined by measurement, it has no place in a theory. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.” – Richard P. Feynman, “You’re unlikely to discover something new without a lot of practice on old stuff, but further, you should get a heck of a lot of fun out of working out funny relations and interesting things.” – Richard P. Feynman, “I don’t believe in honors – it bothers me. During high school, every puzzle that was known to man must have come to me. I have no responsibility to be like they expect me to be. I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem.”, “I am going to tell you what nature behaves like.

Feynman, and Brian Greene at BrainyQuote. In this series of 4 lectures, Richard Feynman introduces the basic ideas of quantum mechanics. This world is not correctly described by the physics which assumes this postulate.” – Richard P. Feynman, “In any decision for action, when you have to make up your mind what to do, there is always a ‘should’ involved, and this cannot be worked out from, ‘If I do this, what will happen?’ alone.” – Richard P. Feynman, “Before I was born, my father told my mother, ‘If it’s a boy, he’s going to be a scientist’.” – Richard P. Feynman, “I wanted very much to learn to draw, for a reason that I kept to myself: I wanted to convey an emotion I have about the beauty of the world.” – Richard P. Feynman, “I’ve always been very one-sided about science, and when I was younger, I concentrated almost all my effort on it.” – Richard P. Feynman, “I was terrible in English. Their knowledge is so fragile!” – Richard P. Feynman, “Working out another system to replace Newton’s laws took a long time because phenomena at the atomic level were quite strange. I have no responsibility to be like they expect me to be. But still, there was the problem of the interaction of light and matter.” – Richard P. Feynman, “I got a fancy reputation. “If you think you understand quantum mechanics, you don't understand quantum mechanics.”, “[Quantum mechanics] describes nature as absurd from the point of view of common sense. And since an accurate value of the momentum of a localized particle cannot be defined by measurement it therefore has no place in the theory.”, “Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy.”, “No one really understands quantum mechanics.”, “I think we can safely assume that no one understands quantum mechanics.”, “You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no real problem. Work as hard and as much as you want to on the things you like to do the best. There are many things I don’t know anything about, such as whether it means anything to ask “Why are we here?” I might think about it a little bit, and if I can’t figure it out then I go on to something else. Let us proceed to compute the second-order term in this series as well. My papa brought me up this way.” – Richard P. Feynman, “I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way – by rote or something. Explore the world. But a few days later he told the faculty member, "You know, I … Yes, Richard Feynman was a very, very interesting man. Richard Phillips Feynman,  (May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model. Richard P. Feynman. Explanation of Richard Feynman's Quantum Electrodynamics (Spherical Electromagnetic Vector Waves) with the Wave Structure of Matter (Spherical Scalar Standing Waves). People search for certainty. Rising to the challenge, he said, "I'll prepare a freshman lecture on it." We now have two degree-3 internal vertices (labeled by times s and t) and two degree-1 external vertices, both labeled by time 0. See more ideas about richard feynman, richard, physics. “Atoms are very special: they like certain particular partners, certain particular directions, and so on. It is the job of physics to analyze why each one wants what it wants.” – Richard P. Feynman, “With the exception of gravitation and radioactivity, all of the phenomena known to physicists and chemists in 1911 have their ultimate explanation in the laws of quantum electrodynamics.” – Richard P. Feynman, “Is science of any value? Richard Phillips Feynman (11 May 1918 - 15 Feb 1988) was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics.
