— Richard Feynman, buch The Pleasure of Finding Things Out
Note to the mother of Marcus Chown, who had admired the profile of Feynman presented in the BBC TV Horizon program "The Pleasure of Finding Things Out" (1981). Written after Chown asked Feynman to write her a birthday note, hoping it would increase her interest in science.

Physics is not the most important thing, love is."
