[ What you say is of course what Einstein believed and what he tried to demonstrate in section 3 with the rock toss, but he misunderstood how light would behave in your isolated frame or anywhere else for that matter. Originally by JesseM It is not that light behaves "The way I want it...

I admit nothing of the kind. What I meant was that there are no purely mathematical contradicitions to be found in the Transformations, they are mathematically consistent and not mathematically contridictory. It is the attachment of significance to them that is faulty and I do not agree that...

Sorry JesseM, I tried to reply to you earlier and had problems with my internet service and today I have been otherwise occpied. I haven't yet tried to use your link but I have read all of it before. I think Einstein gives a very good accounting of all of his Relativity thinking in this book...

I apologize for the personal digression about my Daughter. I spent the day today at the funeral of a dear friend and and at such times my daughter's untimly death and thoughts of her loom heavy in my mind. I do not agree that the Lorentz Transformations follow in the manner you say. I am...

Yes I read it a long time ago but I don't currently have it. It may be online, I haven"t checked. I am currently reading Poincare's "Science and Method" first published in 1908. He also used Lorentz Transformations in ways simular to Einstein but he never did give up the ether concept...

Sylas, you are alway kind to my misteps and I appreciate that. I am keenly aware of everything that you say, but you are attempting to introduce the conclusion as the reason to head toward it. All three of the things you mentioned are as you have said yourself derived from the results of the...

By the way, that 1920 on line version of relativity I'm sure reads the same as these sections in my 15th addition version which is still in print, copyright 1961 by the Estate of Albert Einstein. My copy is a paperback Published by Three Rivers Press ($8.95 US). The 15th edition first appeared...

Most of you seem to think I don't understand what I'm talking about or you think everything I have said is obvious. I do know that Einstein had already developed and had many discussions about time dilation and foreshorting etc. What I also know is that in these early sections of his book...

Dear Ich, Thanks for your concern. Everything I put in quotes is from Einsteins 1916 book "Relativity" and the problem I am dealing with is Einstein's own. I simply put numbers in where he had none and kept it true to his original. In this book Einstein is explaining the reasoning he used...

Dear Jesse M, Thanks for your reply. However I must take exception to all that you say. Section 7 of Relativity is Einstein's 1916 explanation of the reasoning path he took to discovering all of the things you are talking about. You are wanting me to accept that Einstein should have used...

The thought problem in section 7 of “Relativity” is the beginning of Einstein’s rationale for using his version of Lorentz Transformations. He uses a railroad embankment as one “rigid reference-body (frame)”, and a train car on the tracks moving at a constant speed parallel to the embankment as...

This is a slightly altered version of an old problem that is said to be the type of problem that led both Poincare and Einstein to adapt the Lorentz Transformations with a slight change from what Lorentz designed them for. Namely to calculate the contraction of "each body of light" as it moved...

Dear bcrowell, The scientific world never heard of time dilation until Einstein intorduced it along with his explanations about the consequences of Special Relativity. His explanation is in his book "Relativity" starting with section 7 and continuing through section 17 where he talks about...
