American physicist Richard Feynman was born #OTD in 1918.
He developed the Feynman diagrams, a pictorial representation of the mathematical expressions governing the behavior of subatomic particles, which provided a powerful tool for calculating complex interactions among particles. He received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga for their fundamental contributions to the development of quantum electrodynamics (QED).
"...the full appreciation of natural phenomena, as we see them, must go beyond physics in the usual sense. We make no apologies for making these excursions into other fields, because the separation of fields, as we have emphasized, is merely a human convenience, and an unnatural thing. Nature is not interested in our separations, and many of the interesting phenomena bridge the gaps between fields.
Vol. I; lecture 35, "Color Vision"; "The human eye".
The Feynman Lectures on Physics
In addition to his research contributions, Feynman was known for his exceptional teaching ability & engaging lectures. He authored several popular science books, including "Surely You're Joking, Mr. Feynman!" & "What Do You Care What Other People Think?" Many of his lectures & miscellaneous talks were turned into other books: The Character of Physical Law, QED: The Strange Theory of Light and Matter, Statistical Mechanics, Lectures on Gravitation, & the Feynman Lectures on Computation.
