Quotes by Physics There is no authority who decides what is a good idea. Richard P. Feynman physics authority ideas Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?" Richard P. Feynman physics forget looks If all of mathematics disappeared, physics would be set back by exactly one week. Richard P. Feynman week physics would-be So far as we know, all the fundamental laws of physics, like Newton's equations, are reversible. Richard P. Feynman physics fundamentals law I think I can safely say that nobody understands Quantum Mechanics. Richard P. Feynman physics fake-people thinking All theoretical chemistry is really physics; and all theoretical chemists know it. Richard P. Feynman chemistry physics knows Physicists like to think that all you have to do is say, these are the conditions, now what happens next? Richard P. Feynman next physics thinking It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we can discuss. Richard P. Feynman nobody-knows physics knows In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known" with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities. Richard P. Feynman modern effort physics We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation. Richard P. Feynman physics principles law Turbulence is the most important unsolved problem of classical physics. Richard P. Feynman physics important problem As revealed by physics, the truth is so remarkable, so amazing! Richard P. Feynman truth-is physics remarkable In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth. Richard P. Feynman truth-is affair physics Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics. Richard P. Feynman six physics different 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 possibly avoid it, 'But how can it be like that?' ...Nobody knows how it can be like that. Richard P. Feynman physics doe science As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise expect. Richard P. Feynman atheism physics able Physics advances by accepting absurdities. Its history is one of unbelievable ideas proving to be true. Rivka Galchen physics accepting ideas If you miss one day in physics, that's it. Robert Iler physics one-day missing-you The scientists who made the atomic bomb are, in my sense, people with a tragic destiny. You know, there was the US race with Nazi Germany and good evidence that the Germans were more advanced in nuclear physics, and we had to get the bomb first. But then there was the use of that dreadful weapon, or instrument of genocide, and many of the more sensitive scientists turned quickly into anti - nuclear people - and very effective ones. Robert Jay Lifton destiny physics people As a scholarly discipline, economics has always suffered from physics envy. Robert Kuttner envy discipline physics «678910111213141516»
