A Problem in Fourfold Geometry

Published online by Cambridge University Press:  03 November 2016

Extract

We take two bodies P Q which have straight world lines OP KQ. This means in classical language that P and Q have a constant relative velocity. Our object is to find the configuration which an observer U reckons that of nearest approach of P and Q, and to find U’s measure of the least distance.
