That equation has a different form in Einstein's text: 2AB/(t'_A - t_A )= c It's no big deal, of course, but quotes should be verbatim. The difference is: Einstein meant c and not the delay with this equation. You changed the order of terms and concluded, that Einstein meant the delay. But there is no evidence at all, that Einstein even considered the delay, because the word 'delay' or something equivalent is missing in the entire text. >> >> I know, of course, what that equation means. >> >> A is a point in space and B is a point in space.

The equation is NOT wrong (and your remark about notation AB is Formal requirements are also valid for geniusses! so: Einstein had to make clear, what he meant with 2AB. It is obvious from the context, that twice the distance from A to B was meant. Such distances have actually a common notation, (which I cannot easily replicate in ASCII), but has a line on top of AB. If no such line is present, then AB must be interpreted as scalar product of two position vectors A and B. Actually A and B denote points. But you cannot multiply points, because points are physical entities, which cannot be multiplied (like e.g. you cannot multiply an egg with an apople). So A and B must be interpreted as position vectors. Vectors can be multiplied, hence that would be a valid interpretation of 2AB. But 2AB is not twice the distance from A to B. ... TH
