Yes, but there is an acceleration going on because the direction of motion is along the arc of a circle... It's bound to do something... small, but something. -Chuck Harris _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
