The question Is this Heisenberg joke actually real? is closed for the following reason:
This question does not appear to be about history of science and math, within the scope defined in the help center.
The help center lists these topics:
- What influenced a certain scientist or mathematician's work in a certain topic?
- Who discovered or invented this formula or theory?
It is unclear whether question about source for jokes on-topic or not.
FWIW, I have asked a similar question, and it's welcomed: In a popular anecdote, who took 20 minutes to decide that a thing was obvious?
