Note to the mother of Marcus Chown, who had admired the profile of Feynman presented in the BBC TV Horizon program &quot;The Pleasure of Finding Things Out&quot; (1981). Written after Chown asked Feynman to write her a birthday note, hoping it would increase her interest in science. <br class="br">Photo of note published in No Ordinary Genius: The Illustrated Richard Feynman (1996), by Christopher Sykes, p. 161. <br class="br">In a &quot; Quantum theory via 40-tonne trucks http://www.independent.co.uk/arts-entertainment/books/features/quantum-theory-via-40tonne-trucks-how-science-writing-became-popular-1866934.html&quot;, The Independent (17 January 2010), and in a audio interview on BBC 4 (September 2010), Chown recalled the note as: &quot;Ignore your son&#x27;s attempts to teach you physics. Physics is not the most important thing, love is.&quot;
