Happy 107ᵗʰ Birthday to Richard P. Feynman (1918–1988). A pioneering theoretical physicist, Feynman revolutionised quantum mechanics with his path integral formulation and the intuitive Feynman diagrams that make particle interactions easier to visualise and calculate.
During World War II, he worked on the Manhattan Project at Los Alamos, applying his deep understanding of nuclear physics to critical wartime research. After the war, his clear, engaging teaching style at Caltech produced the landmark The Feynman Lectures on Physics, still a foundational text for generations of students. Beyond academia, Feynman served on the Rogers Commission investigating the Challenger disaster in 1986, where his rigorous insistence on scientific integrity helped uncover the true cause.
