Feynman Diagram >> Writing The Integral Explicitly

Classical physicists: "We need exact solutions!" Meanwhile, Richard Feynman's just sitting there like "What if we just... draw some squiggly lines?"

The beauty of Feynman diagrams is that they turned horrifyingly complex quantum field theory integrals into cute little pictures that even undergrads can understand (sort of). While traditional mathematicians were having existential crises over unsolvable equations, Feynman was like "hold my bongo drums" and revolutionized physics with doodles.

The Nobel committee basically gave him a prize for being the ultimate physics hack artist. And that angry guy in the third panel? That's every mathematician who spent years deriving exact solutions only to be upstaged by some feather diagrams and perturbation theory.
