Talk:phi

How is phi pronounced in English - [fai] or [fi:]? (AFAIK pi is pronounced as [pai].) --Kompik 13:43, 20 October 2005 (UTC)


 * It rhymes with pi, tie, high, fly (isn't English pronunciation easy to learn).


 * So why are there /faɪ/ and /fiː/ described? Xonqnopp (talk) 15:16, 9 March 2015 (UTC)


 * It is very odd. Fai is the established pronunciation. I guess some people (who had probably never heard other people pronounce in the normal way) thought that, since it was a letter like b, c, d, etc, it should rhyme with those and it caught on among other people who were unaware of the established pronunciation. Some people also pronounce xi as ksee which sounds a lot like c. They never pronounce pi as pee though.146.199.171.106 13:06, 20 November 2021 (UTC)

 * I suppose this counts:


 * 1963, Psychology Through Experiment (George Humphrey, ‎Jaroslav Antonio Deutsch), page 90:
 * tolerance (Frenkel-Brunswik 1949) for it showed that those persons with the strongest defences against internal conflict, i.e. obsessionals and conversion hysterics, were those least able to perceive the reality-conflicting phenomenon of phi.
 * I can also find a few citations of "phenomenon of (phi movement|perception)". And, of course, citations of "phi phenomenon", but do those count for [[phi]] or only [[phi phenomenon]]? - -sche (discuss) 17:43, 7 August 2015 (UTC)


 * This is citable if citations of "phi phenomenon" are citations of phi, which I guess they are. So, cited. - -sche (discuss) 07:59, 23 September 2015 (UTC)
