:::::::: And may I give you an advise, too? Sometimes it is good to listen to those great minds who actually had the ideas in the first place. Thinking for yourself is all fine and dandy, but sometimes, it seems to be the sensible thing not to ignore a century of textbooks.

::::::::: If your approach is to rely on authoritative, time-tested sources, Clement, then '''why haven't you been quoting the Bible during your many edits to this site'''? Instead, you seem very selective in which sources you quote, and as BHarlan pointed out first below, you don't even seem to interpret your own selective sources correctly.--[[User:Aschlafly|Andy Schlafly]] 20:33, 21 April 2009 (EDT)
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)
