Feynman Quantum Mechanics Quotes & Sayings

The uncertainty principle "protects" quantum mechanics. Heisenberg recognized that if it were possible to measure the momentum and the position simultaneously with a greater accuracy, the quantum mechanics would collapse. So he proposed that it must be impossible. — Richard Feynman

If you think you understand quantum mechanics, you don't understand quantum mechanics. — Richard P. Feynman

No phenomenon directly involving a frequency has yet been detected above approximately 10^12 cycles per second. We only deduce the higher frequencies from the energy of the particles, by a rule which assumes that the particle-wave idea of quantum mechanics is valid. — Richard Feynman

I think we can safely assume that no one understands quantum mechanics. — Richard P. Feynman

It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent. — Richard P. Feynman

Feynman once wrote, I think I can safely say that nobody understands quantum mechanics. — Stephen Hawking

Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter. — Richard P. Feynman

In 1965, physicist Richard Feynman opined, "I think I can safely say that nobody understands quantum mechanics," and the sentiment is equally applicable today. — Sean Carroll

No one really understands quantum mechanics. — Richard P. Feynman

[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 Feynman

Feynman once said, 'Science is imagination in a straitjacket.' It is ironic that in the case of quantum mechanics, the people without the straitjackets are generally the nuts. — Lawrence M. Krauss

I think it is safe to say that no one understands quantum mechanics. Do not keep saying to yourself, if you can possibly avoid it, "But how can it be like that?" because you will go "down the drain" into a blind alley from which nobody has yet escaped. - Nobel physicist Richard Feynman — Robert Lanza
