That statement (of Einstein) was hilarious nonsense. Clocks are man-made devices and time should be understood as a phenomenon in nature. And nature is not supposed to care about what humans have created or read out. Clocks are machines, that imitate the natural flow of time internally and make that flow measurable. But the internal parts of a clock are by no means time or something similar. > >> If we synchronize clocks - they're indicating t'=t; that's what clock >> synchronization means. > > wrong too, you cannot read two clocks same time We have also a delay, if one clock is further away than the other one. Now Einstein didn't consider the delay and didn't figure it out. But that would have been necessary, because the transit time of the signal from the remote clock to the observer follows after the event of reading the clock, hence would add to that reading. So, you would need to measure the delay and subtract that value from your own time or add it to the remote reading, if you wanted to synchronize clocks. But Einstein didn't do that. He didn't even mention 'delay' or 'transit time' or anything similar. ... TH
