Once upon a time, I read a story about Karl Popper giving a lecture on scientific methodology. Afterwards, a chemist stood up and told him that the scientific method Popper was expounding did not match up with his experience, whereupon Popper told him that he was a very bad scientist.

I've been trying to look for that quote, but all I've found on it is this Reddit post. Does anyone have any other leads? Thanks in advance!
