"What I cannot create, I do not understand." — R. P. Feynman
Richard Feynman was an American physicist who significantly contributed to the theory of quantum electrodynamics. He was a curious, tenacious scientist, always looking for the simplest explanation to the problems he encountered. This feature made him not only an excellent researcher but also a great teacher.
He was famous for breaking down complex concepts into simple, intuitive ideas. In particle physics, he devised pictorial diagrams - now known as Feynman diagrams - to reproduce the interactions between electrons and photons. This helped him develop the theory of quantum electrodynamics, which aims at understanding how light and matter interact at the microscopic level.
As a teacher, he inspired the younger generations by making physics accessible to everybody. His lectures are still used by students all over the world, to learn about quantum mechanics, electromagnetism and much more.
