Pythagorean theorem

This is a nice article! Since you mention the Pythagorean theorem in the example of the light beam in the train, why not complete the thought and note that the formula for time dilation follows directly from it? The Lorentz transformations don't actually involve any advanced mathematics. Greg Woodhouse 22:41, 25 June 2007 (CDT)

I'm trying to keep the article pitched as non-technically as possible, since--amazingly--relativity's basic effects are much more accessible than people would have thought in 1905. If you mean to derive Lorentz from Pythagoras, I think that would make a lot of people's heads spin. If you mean just mention the connection in the article, then I think you should work it in if you see a good way to fit it. My only concern about the Lorentz Transformation is that it's kind of its own deal, and paying too much attention to it here might only distract. It's interesting you brought this up, though. I labored over whether to say more about Lorentz, but I came to believe that even though it apparently doesn't require more than high school algebra, the idea of transformation, of mapping one coordinate system onto another is not a high school notion, especially with time involved. I think even the Galilean Transformation would actually cause people more difficulty to fully comprehend than anything else in the article. Thanks for catching my latex typos, by the way.
