Richard P. Feynman Quotes About Quantum Mechanics

Quotes about: Quantum Mechanics

• If you think you understand quantum mechanics, you don't understand quantum mechanics.

  Richard P. Feynman

  Thinking, Mechanic, Quantum

• What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.

• 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.

  Richard P. Feynman

  Looks, Want, Problem

  Richard P. Feynman (2015). “The Quotable Feynman”, p.76, Princeton University Press

• 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. It has not yet become obvious to me that there's no real problem. I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem.

  Richard P. Feynman

  Real, Ideas, Two

  "Simulating Physics with Computers". Richard P. Feynman, "International Journal of Theoretical Physics", Volume 21, 1982.

• [Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd.

  Richard P. Feynman

  Views, Common Sense, Religion

• I think I can safely say that nobody understands Quantum Mechanics.

  Fake People, Thinking, Physics

  The Character of Physical Law ch. 6 (1965)

• There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time ... On the other hand, I think I can safely say that nobody understands quantum mechanics.

  Richard P. Feynman

  Believe, Men, Thinking

  The Character of Physical Law ch. 6 (1965)

• If I say [electrons] behave like particles I give the wrong impression; also if I say they behave like waves. They behave in their own inimitable way, which technically could be called a quantum mechanical way. They behave in a way that is like nothing that you have seen before.

  Richard P. Feynman

  Science, Giving, Way

• 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

  Science, Doe, Physics

  "The Character of Physical Law". Book by Richard P. Feynman, 1965.

• Unless a thing can be defined by measurement, it has no place in a theory. 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.

  Richard P. Feynman

  Science, Momentum, Measurement

  Richard P. Feynman, Robert B. Leighton, Matthew Sands (2013). “The Feynman Lectures on Physics, vol. 3 for tablets”, Basic Books

• No one really understands quantum mechanics.

  Richard P. Feynman

  "Does quantum mechanics carry the seeds of its own destruction?". Physics World magazine, 1991.

• I think we can safely assume that no one understands quantum mechanics.
