One of the delightful unforeseen consequences of the 'Dick's Birthday' project is the discovery of a very nice little paper by Daniel A Russell, Kettering University, Michigan : "On the sound field radiated by a tuning fork" Am. J. Phys., Vol. 68, No. 12, 1139-1145, December 2000 . To quote: Dan Russell has also produced a prize-winning website of animations relevant to teaching 'vibrations and waves'. He writes to us: "Richard's 1966 AJP paper on tuning forks provided the impetus for my experimental investigations." On the other hand, Google and MSN searches for 'tuning fork' give as the first hit a colourful prize-winning presentation by a Norwegian schoolboy who decided that the "assumption and formula for the intensity" made by "an old physicist by the name Richard M. Sillitto" was "only correct due to the distance (R), but not to the angle (q)". |
