Group, This is is a brief reply from a fellow on the BA board (coincidentally named Lorentz, BTW) stepping in to respond to words I wrote to another BA-er named Worzel. Worzel had originally asked me what I thought of Einstein, I believe, and I responded. Two subjects came up. Michelson-Morley, and the Twins Paradox. Someone else reported (not repeated here) on BA during the course of this conversation that I was wrong about the purpose of MM. They said it was to measure the movement of the earth through the aether. I felt that that was simply linear orbital speed of the earth around the sun, and that any measure of that was, by corollary, a proof that the earth rotated. There was some disagreement with that summation, and it was a minor point of contention on the board as I recall. But I still hold to that understanding. What else was MM trying to do if not prove the earth moved through space? Wouldn't moving through aether mean the same thing? Wouldn't proof of it mean proof of rotation, ergo? It was a bit off topic for the thread there, but that's what happens sometimes. I thought it might be of interest. In geostasis, Gary ------------------------------------ Gary wrote: Worzel, my off the cuff feelings about Einstein and all this relativity stuff he is credited for, is that it did loads of good to offset the actual scientific results of the Michelson Morley experiments. Those gents were out to prove the earth moved through space, and thereby rotated, and came up with zip movement. Lorentz replied: That wasn't the only reason. Without Einteinian-Lorentzian type relativity, the laws of electrodynamics as described by Maxwell contradicts the laws of mechanics as described by Newton. What got Einstein going was mainly questions about radiation pressure (part of electrodynamics), which when examined superficially seem to be nonNewtonian. The earth not moving was not really an issue in Einstein's head, maybe in Lorentz's. Gary wrote: For over 20 years these experiments were replicated all over the world. Same result. Earth is still in the heaven. But then Einstein was promoted up as a science superstar with ideas from Poincare, Lorentz, and others and he saved the day. Lorentz replied: Gary, did you know Poinare and Lorentz both new about Einstein's theory, both supported him, and both refused to take credit from him. In fact, it was Lorentz who first called Einstein a genius and is to a large part responsible for Einstein's diefication. Did you ever read any of Lorentz's or Einstein's papers? I did. Lorentz explains Einstein's theory, and how it was better than his, in great detail. I personally think Lorentz explains Einstein better than Einstein explains Einstein. Read "Theory of the Electrons." Gary wrote: Let me ask you [talking to Worzel. GLS] the one question I can about Einstein. What is the resolution to famous Twin's Paradox? Lorentz replied: Resolution: A force is acting on the twin in the spaceship, no force is acting on the twin on earth. From the spaceship twin's point of view, a foce is acting on him that violates Newton's third law. The pseudo-gravity that spaceship twin fells has no opposing force, no action-reaction. Earth twin can assign a body with a reaction force for every body with an action force. In special relativity, an inertial frame is one where both the laws of mechanics and the laws of electrodynamics hold true (Einstein's 1905 paper). GaryLShelton@xxxxxxxxxxx
