Einstein was the first to insist that the priniciple physics facts were those stated in the two postulates, and showed that all the results that had been guessed by others before him (including Lorentz, Poincare, Voigt, Fitzgerald, and Larmor) were the direct consequences of these two fundamental principles. The two fundamental principles also led to a number of other conclusions that his predecessors had not guessed. While Einstein's work was not singular in its originality, as you note, he did figure out what the real underlying physics was, rather than getting it ass-backwards as so many of his predecessors did. This is not uncommon. Many of the results of QCD were guessed well before QCD (a theory based on SU(3) symmetry) was formulated, but QCD was the first to get the fundamental physics right. Fermi and Yukawa and others guessed many of the features of the weak interaction, but it wasn't until Weinberg, Glashow, and Salam that the real basis for the weak interaction was understood. Credit is often given not to those who guess some of the features first, but to those who make the breakthrough to provide the fundamental understanding. > In doing so, he made a series of errors, There are no errors. > but the results > were always what were of expectations.

Each of the resolutions can be derived from each of the others. This would not be possible if they were in direct contradiction. Your fond desire that there should be one and only one way of looking at the resolution to the puzzle, for the sake of your clarity, is not commonly shared. > Thus, effectively, the twin's paradox has not been > resolved.

The principle of relativity as YOU understand it is certainly invalid. That has been recognized here for a long time. However, the principle of relativity as correctly stated stands. |
