ClementB, doesn't "a certain velocity V" imply that Einstein is saying that the speed does not change during the scope of the problem?
ClementB, doesn't "a certain velocity V" imply that Einstein is saying that the speed does not change during the scope of the problem?
For instance, if I say "If a certain man V is President for two full terms, V may not be elected to a third term" or "There is a certain function f such that if a car is traveling at a certain velocity V that is less than the escape velocity, then it will fall to Earth in less than time f(V)", then the variables are not changing over the scope of the problem, no? And since some problems take place over very long periods of time, the velocity is assumed not to change over that whole period, no? And doesn't that imply that the speed of light is constant, no matter how far your twin travels? [[User:BHarlan|BHarlan]] 18:26, 21 April 2009 (EDT)

:::::::::: The Bible is my source of inspiration. I keep it out of my science or history classes, though.
:::::::::: Yes, I'm selective in my sources: on science, I quote scientists. I'm humble enough to know that I can't improve the insights of the greatest minds of the last century, but I am confident that I can understand what they were talking about. If you read the quotes above with an open mind, you'll find that your wording of the postulates is lacking: it covers at most half of the original of Einstein, and leaves out the baffling part. You scold me for respecting to much ''what someone else said''. May I quote Sir Isaak Newton: ''If I have seen further it is only by standing on the shoulders of giants.''
:::::::::: I think it is prideful to refuse to climb on these shoulders, and to remain willfully in the shadows of the giants.
:::::::::: And may I say that you offered no quote, neither Biblical nor scientific, for your version of the postulate? I got the impression that you thought it up by yourself. But which sources did you use?
:::::::::: BTW, BHarlan talks about a conclusion drawn from the postulates, not the postulates themselves.
