The Weyl Definition of Redshifts
Harvey, Alex
European Journal of Physics, v33 n4 p823-835 Jul 2012
In 1923, Weyl published a (not widely known) protocol for the calculation of redshifts. It is completely independent of the origin of the shift and treats it as a pure Doppler shift. The method is comprehensive and depends solely on the relation between the world lines of source and observer. It has the merit of simplicity of statement and generality. We illustrate the protocol by application to several standard situations. As a matter of historical interest, we include, in an appendix, the earliest known application of the Doppler principle. This was by Romer who used it to calculate the speed of light. (Contains 4 figures and 11 footnotes.)
