Physics
Feynman Diagrams
Quick fact
Feynman originally created these diagrams to help himself think, but they were so effective that they became the universal language of particle physics—despite initial resistance from some colleagues who saw them as too informal.
Why this is interesting
You've likely seen squiggly lines and arrows connecting particle dots—but what do these drawings actually represent? Feynman diagrams turn impossibly complex quantum math into simple sketches.
