Richard Feynman talks about his childhood and teenage years in Far Rockaway, teaching himself advanced mathematics before he even reached high school.
Recorded in the 1970s by his friend Ralph Leighton, this conversation covers his self-directed study of trigonometry, his invention of a private mathematical notation to replace "confusing" standard symbols, and his competitive streak on the high school algebra team.
I've added historically accurate photos and scans of Feynman's actual personal notebooks from the 1930s to give visual context to the story as it unfolds.
