# What physicist was famous for his out-of-the-box problem solving methodology using concept maps?

I remember having read on Wikipedia some time ago the page of a 20th century physicist. There was a subsection about his strategy for problem solving that involved drawing a concept map of the objects involved in the problem and then switching them around. I can't however remember the precise anecdote, nor the name of the physicist.

Details that I do remember, ranked by confidence that I recall them correctly:

• Male physicist
• Used concept maps (or mind maps) and then switched arrows and nodes around for out of the box thinking
• There was an anecdote along the lines of moving the Earth from its orbit (which would point to an astrophysicist)
• Might have been related the Los Alamos laboratory

Does anybody have a clue who it might be? My initial instinct was either Fermi or Szilard but their respective Wikipedia page does not contain anything relative to creative problem solving strategies.

• You're not thinking of Feynman diagrams here? They are not quite what you describe but a rather specific graphical method to represent complicated mathematics. But Richard Feynman was generally famous for out-of-box thinking and for lots of weird anecdotes, so perhaps he used some kind of concept maps too. Dec 11 '21 at 9:06
• Concept maps were introduced by Novak in 1970s for educational purposes, but he was a biologist, not a physicist. Mind maps by Buzan at about the same time, but he was a popular psychology author. Dec 13 '21 at 11:49
