Nobel laureate Hans Bethe was a friend of mathematician-physicist John von Neumann, and he once said:

"I have sometimes wondered whether a brain like von Neumann's does not indicate a species superior to that of man"


"[von Neumann's] brain indicated a new species, an evolution beyond man"

This indicates that Bethe admired von Neumann's work very much.

My question is: Did he think the same about von Neumann's quantum logic? Did he like it?

    $\begingroup$ By "like," do you mean that he agreed with the math, or that he agreed with the conclusion, or just that he thought it looked cool? $\endgroup$ – Carl Witthoft Jan 8 at 13:46

    $\begingroup$ There is no way to answer a question stated like this, since Bethe is no longer with us. A proper form would be: "What did Bethe write or say, if anything, about quantum logic?" $\endgroup$ – Alexandre Eremenko Jan 8 at 18:57
  • $\begingroup$ My guess is that he did not think about it. It was a mathematical toy that physicists paid little attention to even in its heyday. $\endgroup$ – Conifold Jan 8 at 23:41
