Re-entrant Motion in Special Relativity

Abstract

I BELIEVE that Dr. Phipps is mistaken in his assertions (1) that the round trip velocity vr.t. of a point on the edge of a rotating disk, defined by vr.t. = ωr = 2πr/T, where T is the period, is not equal to the instantaneous edge velocity, v, and (2) that ωr can become greater than c, the velocity of light.
