Richard Feynman probably didn't say, "If you think you understand quantum mechanics, then you don't." But he did say enough to make it clear that's how he regarded the quantum world. Here's a video that does a great job of showing why. https://t.co/OcHtwkxxnX

I think that I can safely say that nobody understands quantum mechanics.--Richard Feynman

@ValaAfshar @dancindoti @jaketapper No slouch. Richard Feynman, American theoretical physicist, who worked on the path integral formulation of quantum mechanics, theory of quantum electrodynamics, physics of the superfluidity of supercooled liquid helium, and particle physics for which he proposed the parton model.
