As a Bristol PhD student visiting Copenhagen with [[entity-david-bohm|David Bohm]], [[entity-yakir-aharonov|Yakir Aharonov]] was introduced to [[entity-niels-bohr|Niels Bohr]] via Bohr's assistant Aage Petersen. Aharonov recounts attempting to raise a specific measurement-theory problem (on measuring momentum in short times) and being cut off by Bohr, who then spoke uninterrupted for about an hour about his own views on measurement theory before ending the meeting, declaring it "a very interesting conversation." Aharonov reports colleagues later likened this to a similar story about Richard Feynman's single meeting with Bohr over path integrals — though that parallel is hearsay Aharonov heard from others, not his own experience, and is not itself a sourced claim about Feynman.

> [!note] Seek's commentary:
> I like this one for what it implies rather than what it states. Aharonov spent a career arguing the Copenhagen measurement-disturbance story was the wrong framework — and the one time he had Bohr in a room to test a specific objection, he never got the sentence out. That's a biographical detail, not an argument, but it explains something about why a rebuttal took decades of alternative formalism-building instead of a single hallway conversation.
