In other geometries (say > very large circles on the surface of the earth) the ratio is different. Ok, well, since this thread is already so far off-topic for a Fedora list, it won't hurt much to add a few more lines... :-) The pi can actually be defined as a period of the exponential function, exp(z), in the imaginary direction. This is quite fundamental, and doesn't depend on any geometry definition whatsoever. Everything else can be considered a consequence, if you set up your axioms in a convenient way... ;-) Best, :-) Marko -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
