"I'm not a serious person. I'm just a serious scientist."
"I was never a very good student, and I always had trouble with math. I was always in the bottom of the class in math."
"What I cannot create, I do not understand."
"I have a lot of fun. I've always had a lot of fun. I don't know why I should stop."
About Richard Feynman (1918-1988)
American theoretical physicist who shared the 1965 Nobel for QED, developed Feynman diagrams, and wrote the Feynman Lectures on Physics. Closely associated with Julian Schwinger (co-Nobelist for QED) and Murray Gell-Mann (Caltech rival and Eightfold-Way physicist). For an intellectual contrast, see Deepak Chopra, physician and quantum-mysticism author — Feynman's Caltech 'cargo cult science' commencement address is the precise template for what he saw as misuse of physics terminology — Chopra-style appropriation of quantum vocabulary for metaphysical claims is the canonical example of what Feynman called 'fooling yourself'.

Understanding this quote
What it means
True research exists only in the territory of the unknown. Once a method or answer becomes established knowledge, it transforms into technique or engineering. Research is defined by uncertainty and the active pursuit of understanding something that nobody yet fully grasps. The moment a process becomes routine and reproducible by following known steps, it has crossed from discovery into application.
Relevance to Richard Feynman
Feynman built his career at the frontier of quantum electrodynamics, developing entirely new mathematical frameworks like path integrals and Feynman diagrams where no established methods existed. He thrived on genuine puzzles, whether cracking safes at Los Alamos or rethinking quantum mechanics from first principles. His famous curiosity was inseparable from discomfort with the unknown, which he treated as a feature, not a burden.
The era
Post-World War II science experienced massive institutionalization, with government and corporate funding flooding into 'research' departments often doing routine development work. The Cold War and space race blurred lines between applied engineering and genuine discovery. Feynman, working through this era at Caltech, pushed back against credential-chasing and the inflation of the word 'research' to cover work that was really sophisticated problem-solving using already-understood physics.
