Richard Feynman, over the course of his long career, wanted to convince students and even the public that quantum theory does not make sense. In his 1965 textbook on Quantum Electrodynamics (QED), the theory for which he won the Nobel Prize, he wrote:
The theory of quantum electrodynamics describes Nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you accept Nature as She is—absurd.
