It is, on the face of it, self-contradictory. Well, the reason was that scientists reported the results of the Michelson-Morley experiment to be that a cesium clock in either frame of reference would show the speed of light to be c. The equations that show this would be x=ct and x'=cn' instead of x=ct and x'=ct' used by Einstein because t' is defined t'=t in the Galilean transformation equations. So a clock running slower that t'=t in the moving frame of reference has to be represented by a different variable n'. It does not have to be n', that was just the one I used. However, this only describes the position of a photon traveling along the x axis in the positive direction. A photon traveling along the x axis in the negative direction has a velocity of -c, not c, so to describe the coordinates of a photon traveling either direction, we have to use w=velocity of light. > Could you provide a physical picture (a Gedankenexperiment, as it > were) which these expressions are supposed to correspond to? The best example of how this works is Einstein's example of the two strikes of lightning. Lightning strikes the front and rear of a moving train, leaving marks on the front and rear of the train and marks on the railroad track. The distance between themarks on the train is the length of the train, and the distance between the marks on the track is the length of the train, proving there is no relativityof simultaneity or distance contraction. As the Galilean transformation equations show, x'=x-vt. t'=t A cesium clock on the train shows a time of n' for light from the lightning at the rear of the train where n'=t(1-v/c) x'=cn' A cesium clock on the train shows a time of n' for lightning at the front of the train where n'=t(1-v/(-c) = t(1+v/c) x'=(-c)n' > > Velocity of light is w, not c, because the velocity of a photon > > traveling on the x axis of a set of Cartesian coordinates in the > > negative direction is -c, not c. �The Lorentz equations ignore this > > fact by leaving the equations in an unreduced form so that c is always > > squared in those equations. � (-c)(-c)=c^2 > > Irrelevant.

The speed of the planet Mercury is 30 miles per second. At that speed, the Lorentz equations show that a cesium clock on Mercury would be slower than a cesium clock that is not moving. The equations for time n' give the same result to several decimal places at that velocity. > Nonetheless, do you actually have detailed calculation of these > effects that prove your claim? Detailed enough. w=x/t=x'/n' = (x-vt)/(t-vt/w) = (x-vt)/(t-vx/w^2) = (x-vt)gamma/(t-vx/c^2)gamma = x'Lorentz/t'Lorentz > Remember the burden is on the challenger to prove his own claim, not > on the incumbents to disprove the challenger's claim (as a mathematics > professor said once, if he had to read what every crank puts up on, > e.g., arXiv.org, he wouldn't have the time for anything else).

The Jews said an angel of God went through the camp of the Assyrians and killed 186,000 of them. They certainly seem to have ended up dead some way. Chaldean historians said they died of plague. ================================== The plague existed (and there may still be some of the bacteria in some laboratory, somewhere).
