Perfectly reasonable deviations from the beaten track

This collection offers a direct, unmediated insight into Feynman's personal thoughts and experiences through his own words, rather than through the interpretation of a biographer. It provides a more intimate and less filtered perspective on his life and scientific journey.

The letters in this collection touch upon various periods of Feynman's life, including his time at Los Alamos during the Manhattan Project. Readers will find his personal reflections and observations from that significant historical period.

This book complements other well-known works by and about Feynman, such as "Surely You're Joking, Mr. Feynman!" and "What Do You Care What Other People Think?", by providing the raw, unedited source material of his correspondence. It offers a deeper dive into the personal context behind many of the anecdotes and philosophies presented in his more narrative-driven books.
