Richard Feynman: Frasi in inglese
Richard Feynman libro 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. <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 " 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", The Independent (17 January 2010), and in a audio interview on BBC 4 (September 2010), Chown recalled the note as: "Ignore your son's attempts to teach you physics. Physics is not the most important thing, love is."
“Physics is like sex: sure, it may give some practical results, but that's not why we do it.”
Does not appear to be from any of his books or cited in a biography. A Google Books search shows that the oldest book citing "physics is like sex" is Scary Monsters and Bright Ideas (2000) by science broadcaster Robyn Williams. On p. 44, this book claims: "Einstein said, 'You do not really understand something unless you can explain it to your grandmother'. Richard Feynman added, 'Physics is like sex: sure, it may give some practical results, but that's not why we do it'." Given that Einstein didn't really say the former, it's likely that Feynman didn't really say the latter.

same passage in transcript: video http://www.youtube.com/watch?v=-2NnquxdWFk&t=16m46s <br class="br">The Character of Physical Law (1965) <br class="br">Variante: In general we look for a new law by the following process. First we guess it. Then we compute the consequences of the guess to see what would be implied if this law that we guessed is right. Then we compare the result of the computation to nature, with experiment or experience, compare it directly with observation, to see if it works. If it disagrees with experiment it is wrong. In that simple statement is the key to science. It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is – if it disagrees with experiment it is wrong. That is all there is to it.
