Dear Mrs. Chown, Ignore your son's attempts to teach you physics. Physics isn't the most important thing. Love is. Best wishes, Richard Feynman.In a audio interview on BBC 4 in September 2010, Chown himself stated that the note said: "Ignore your son's attempts to teach you physics. Physics is not the most important thing, love is." — but this appears to be a casual use of the paraphrase or summation of its contents, for published photographs of the note reveal that it is phrased as quoted above from No Ordinary Genius : The Illustrated Richard Feynman.
