Richard Feynman published the book 'Theory of Fundamental Processes' in 1961.

Richard Feynman, along with Edgar, Klein, Lielausis, and Steinberg, conducted mapping experiments with r mutants of bacteriophage T4D in 1962. This research contributed to the understanding of genetic mapping and viral genetics.

In 1964, Richard Feynman served on the California State Curriculum Commission, where he expressed his dissatisfaction with the mathematics textbooks that were being used in schools. He criticized the focus on topics like sets, which he believed were not practical for fields like theoretical physics, engineering, or business arithmetic.
