Richard Feynman (1918–1988) was an influential American physicist renowned for his work in quantum mechanics and quantum electrodynamics (QED). He introduced Feynman diagrams, graphical representations used in quantum field theory to visualize particle interactions. Feynman, along with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965 for their contributions to QED. Feynman was not only a brilliant scientist but also an engaging teacher and communicator of science. His popular science books, including “Surely You’re Joking, Mr. Feynman!” and “What Do You Care What Other People Think?”, made complex concepts accessible to a wider audience. Feynman’s legacy extends beyond his scientific achievements; his enthusiasm for discovery and his unique teaching style continue to inspire scientists and enthusiasts alike.
