“What Do You Care What Other People Think?”

Richard Phillips Feynman, Ralph Leighton

Biography and memoir

First published: 1988
Print length: 342 pagesG.K. Hall, 1990

Description

Drawn from recorded conversations with his friend Ralph Leighton, this collection lets physicist Richard Feynman revisit the experiences that shaped his restless, skeptical way of thinking. Its most personal passages recount his relationship with his first wife, Arline, while other episodes follow his appetite for puzzles, travel, mischief, and unconventional encounters. A substantial section turns to his service on the commission investigating the Challenger disaster, where his insistence on testing assumptions brings engineering evidence into conflict with institutional habits and official language. The conversational structure moves easily between intimate memoir, comic anecdote, and public inquiry. Throughout, Feynman asks what it means to think independently when affection, reputation, bureaucracy, and other people’s expectations all exert their own pressure.

About Richard Phillips Feynman

Richard Feynman was an American theoretical physicist whose books grew largely from lectures, recorded conversations, interviews, and public investigations. His subjects range from quantum electrodynamics and the behavior of subatomic particles to scientific education, institutional failure, and the practical habits of curiosity. He explains by rebuilding a problem from elementary questions, shifting perspective, and testing an idea against a concrete example. The Feynman Lectures on Physics preserves this classroom method on a broad scale, favoring physical intuition and connections between problems over formulas presented as settled rules. In QED, he uses visual devices such as clocklike arrows to lead nonspecialists through the probabilities governing light and matter. His memoirs use a looser, episodic structure. Surely You’re Joking, Mr. Feynman! assembles experiments, pranks, arguments, and intellectual detours into a self-portrait, while What Do You Care What Other People Think? moves between intimate recollection and the Challenger inquiry. In both scientific and autobiographical writing, his recurring method is to distrust received language, isolate the underlying question, and follow the evidence.

About Ralph Leighton

Ralph Leighton is an American biographer whose work grows out of sustained conversation, personal friendship, and an appetite for difficult quests. His best-known books emerged from recordings of the physicist Richard Feynman telling stories from his life. In “Surely You’re Joking, Mr. Feynman” and What Do You Care What Other People Think?, Leighton shaped voice-led material into direct, conversational narratives that reveal character through anecdotes, puzzles, travel, scientific curiosity, and skepticism. His contribution is less that of a detached chronicler than of an attentive listener and arranger, preserving the speaker’s rhythms while giving disparate recollections coherence. Tuva or Bust! turns to Leighton’s own long pursuit of reaching Tuva after a casual remark by Feynman, combining memoir with research into the region’s history, language, culture, and bureaucratic inaccessibility. As founder of Friends of Tuva, he extended that fascination beyond the page. Across these works, curiosity becomes a practical method built on listening, investigation, and persistence.
