From: utzoo!utcsrgv!thomson Newsgroups: net.misc Title: Re: Clock Problem Article-I.D.: utcsrgv.915 Posted: Fri Jan 21 13:29:20 1983 Received: Fri Jan 21 14:27:16 1983 References: ucbvax.628 Wayne Christopher claims that special relativity is not applicable to the soon-to-be-famous "whirling digital clock" problem because the clock (display) is accelerated. SR requires only that the OBSERVER be in a local inertial frame, if the clock hypothesis is accepted (i.e. that time dilation effects depend only on instantaneous velocities, not on acceleration) and this hypothesis has been verified for very large accelerations. SR is certainly applicable, and if the whole clock were whirled rather than just the display it would indeed run slow.
