M. Fourier was looking at the problem of heat transfer in cannon barrels, which, in 2D is a ring (aka a continuous periodic function). http://en.wikipedia.org/wiki/Joseph_Fourier has more info (including the interesting thing that I didn't know before, about his discovery of the greenhouse effect) _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
