No. One part of it (A) is axiomatic, but the entirety is a physical theory, in that it models physical phenomena (within its domain). > It is (or originally was at > least) based on postulates, and from those it models physical reality > (which then allows one to experimentally verify the predictions) The theorems derived from the postulates form an axiomatic system.

No physical theory can be purely axiomatic -- Aristotle essentially tried that and it failed even him. I don't know what "purely physical" means in this context, but any mathematical model will not be "physical" (it will be a MODEL). Today, only theories based on mathematical models are acceptable to the community. Tom Roberts

It does not satisfy the null results of the MMX in general. <shrug> Thus, part (A) should read: A) a set of mathemaGical conjectures On Jun 29, 8:54 pm, Tom Roberts < wrote: > LET (LR) starts out with an implicit postulate: there is a unique inertial frame > in which the ether is at rest.

I don't know what mathematical model of LET you understand it as, but clearly, the Lorentz transform is a subset of Larmor's transform. The Lorentz transform satisfies the principle of relative, but Larmor's transform in general does not. <shrug> For your review, the following is Larmor's transform involving the 2 observers (1 and 2), the observed (3), and the absolute frame of reference (0). ** dt1 = (dt0 B01 dx03 / c) / sqrt(1 - B01^2) ** dx13 = (dx03 B01 c dt0) / sqrt(1 - B01^2) ** dy13 = dy03 ** dz13 = dz03 ** dt2 = (dt0 B02 dx03 / c) / sqrt(1 - B02^2) ** dx23 = (dx03 B02 c dt0) / sqrt(1 - B02^2) ** dy23 = dy03 ** dz23 = dz03 Where ** dtI = Time flow at I ** dqIJ = Parameter dq (dx, dy, dz) at J as observed by I ** B0I c = Absolute speed of I Written in this way implies that 1 and 2 are moving in parallel relative to 0. With that, the above equations do become the following which is the Lorentz transform. ** dt1 = (dt2 B21 dx23 / c) / sqrt(1 - B21^2) ** dx13 = (dx23 B21 c dt2) / sqrt(1 - B21^2) ** dy13 = dy23 ** dz13 = dz23 ** dt2 = (dt1 B12 dx13 / c) / sqrt(1 - B12^2) ** dx23 = (dx13 B12 c dt1) / sqrt(1 - B12^2) ** dy23 = dy13 ** dz23 = dz13 Notice ** B12 = - B21 > LET (LR) has an amazing and unexpected cancellation that makes the ether frame > completely unobservable FOR PHYSICAL MEASUREMENTS. But its transform equations > were all derived starting from that unique inertial frame. Don't rejoice about this cancellation of 0 from Larmor's transform. In a more general case where 1 and 2 are not necessarily moving in parallel relative to 0, this 0 does not cancel out. Yours truly has explained that below. http://groups.google.com/group/sci.physics.relativity/msg/c5a0a3c587fd4df4?hl=en On Jun 29, 9:00 pm, Tom Roberts wrote: > One part of it (A) is axiomatic, but the entirety is a physical theory, in > that it models physical phenomena (within its domain). For example, in Larmor's transform, when 1 and 2 are not necessarily moving in parallel to each other relative to 0, the temporal equations can be written as follows. ** dt1 = (dt0 [B01] * [ds03] / c) / sqrt(1 - B01^2) Very trivially, when 3 is observing 1 back, the following equations holds. ** dt3 = (dt0 [B03] * [ds01] / c) / sqrt(1 - B03^2) Where ** [dsI] = Change of spatial vector at I ** [A] * [B] = Dot product of the two vectors [A] and [B] One can easily and very trivially combine the above two equations into the following. dt1 sqrt(1 - B01^2) + [B01] * [ds03] / c = dt3 sqrt(1 - B03^2) + [B03] * [ds01] / c Notice the frame of reference called 0 also known as the absolute frame of reference does not go away. This follows closely how high speed particles are observed to exhibit time dilation relative to an observer moving more slowly relative to the absolute frame of reference. All your observations can be explained with Larmor's transform based on the absolute frame of reference thus breaking the precious symmetry while the Lorentz transform is a complete mathematical bogus. > The theorems derived from the postulates form an axiomatic system.

Try not to be sloppy with the symbols just like Einstein the nitwit, the plagiarist, and the liar did in his infamous 1905 paper on relativity. <shrug> Have you finally figured out the nitwit's mathemagical tricks of deriving (E = m c^2 / sqrt(1 - v^2 / c^2)) through a serious of mistakes namely being very sloppy on the symbols? > No physical theory can be purely axiomatic -- Aristotle essentially tried that > and it failed even him.

Have you finally realized that SR fails any mathematical integrity right off the bat? SR manifests the twins' paradox which is absolutely nonsense. SR should never be accepted as a valid model of the real world. All real life observations are based on Larmor's transform with all observations eventually have to reference back to the absolute frame of reference. Without the so-called symmetry, there is no paradox, and the GPS functions like a charm. <shrug> Just in case if you have finally realized your very basic mistakes, try not to jump off the tallest building in the Chicago area. There are still a lot of mysticism beyond SR to be exorcised. <shrug>

Can you quote it, or give a reference to it? If you can't then it looks like you are lying.
