Not quite. In LET you must, of course, choose the ACTUAL ether frame. It was not apparent to Lorentz that one could not do this via any experiment -- he simply assumed that there is such a frame and one naturally computes using it, whatever it is. It is serendipity that the inability to experimentally identify this frame does not matter, because the choice of the ether frame does not affect the predictions of the theory for any experiment. I am not concerned here with the intellectual route which led to SR or the intellectual differences between SR and LET merely in mathematical terms how the two theories are related. In LET one can arbitrarily choose any FoR as the ether frame so the option is open to always choose the observer's FoR as the ether frame. Mathematically SR is the equivalent of doing just that which is why SR and LET are mathematically equivalent. Close enough, as long as one remembers this applies only to EXPERIMENTAL PREDICTIONS. I was not trying to deal with anything else. Now it occurs to me that this, the SR approach, is actually one of two possible approaches which would rid LET maths of the totally arbitrary and unnecessary complication of an aether FoR. That is not really "the SR approach", that is, rather, your perversion of SR to force its round peg into the square hole that is LET. The SR approach from the perspective of LET maths which is what I am describing. One simply cannot "rid" LET of the ether frame. Computationally one can take a shortcut, as you say. That is my point. One can do the maths without having a FoR which is separate and different to the other FoR you are considering. You can make it common with one of the FoR you are considering. The other is to do LET maths always choosing the source frame as the aether frame. But it simply does not make sense for the ether to be at rest in multiple frames. This totally ignores the underlying theoretical basis of LET. Agreed but if we are simply looking at LET as a mathematical approach which gives the right answer, this doesn't matter. It is obvious that SR and LET will give the same results because SR is the mathematical equivalent of choosing the observer's FoR as the aether frame and we know that LET maths is not affected by the choice of aether frame. In SR if one changes observer then in terms of LET that is changing the FoR you designate as aether frame - this totally ignores the underlying theoretical basis of LET but it does show why the two are mathematically equivalent. Today SR has no pretensions to address physical processes, it is simply mathematical modelling, This is not merely SR, but all theories of modern physics. We have learned a thing or three since 1904. In the abstract, it should be QUITE CLEAR that the most that human beings can aspire to is to make models of the world -- we can never actually "know" what Nature herself is really doing. We can only make models and test them, which is known as science. Again considering it from the perspective of LET then what SR does is change 'aether frame' every time you change observer. No. You are attempting to apply ancient terminology to SR. The words simply do not fit. You need to LEARN SR, and its vocabulary. No. again I am talking about LET purely as a mathematical approach and how SR may be viewed from that context from a compatibility PoV. AT THIS POINT YOU DO AN UNACKNOWLEDGED SNIP AND FAIL TO ANSWER THE QUESTION. Now ballistic theory is also the *mathematical* equivalent of making the source frame and aether frame one and the same Not at all! Ballistic theory is based upon the assumption that light (whatever it is) travels away from the source at c in all directions. In a wave model when the source is stationary w.r.t the aether light travels away from the source at c in all directions. No ballistic theory includes relativistic kinematics. I didn't claim it did, neither was I trying to claim that ballistic theory and LET are equivalent. What I was saying is that it is possible to do the maths of LET choosing the source as the aether FoR without changing any of the predictions. My suggestion was that using that approach to do relativistic maths would more easily *highlight the differences* between relativistic maths and the maths of ballistic theory in that you then have in common the fact that both are mathematically equivalent to assuming that the source is stationary w.r.t the aether although neither relativists nor ballistic theory supporters would accept that an aether is involved of course. -- John Kennaugh |

John Kennaugh- Hide quoted text - - Show quoted text - The funny,funny,funny reason for warped space based on the lament of light leaving a star goes to waste if it is not bent - "This conception is in itself not very satisfactory. It is still less satisfactory because it leads to the result that the light emitted by the stars and also individual stars of the stellar system are perpetually passing out into infinite space, never to return, and without ever again coming into interaction with other objects of nature. Such a finite material universe would be destined to become gradually but systematically impoverished." http://www.bartleby.com/173/30.html I had to read it several times to make sure I was'nt hallucinating,instead,that pre-Galactic discovery statement from 1920 along with the rest of those paragraphs is genuinely hilarious.I have seen comments supporting and attacking Albert but I have yet to see another person actually laugh at the reasoning.Pity !. |

And thus it is rare that mathematicians are intuitive and that men of intuition are mathematicians, because mathematicians wish to treat matters of intuition mathematically and make themselves ridiculous, wishing to begin with definitions and then with axioms, which is not the way to proceed in this kind of reasoning. Not that the mind does not do so, but it does it tacitly, naturally, and without technical rules; for the expression of it is beyond all men, and only a few can feel it." Blaise Pascal It is a comfort to see what happens when men try to abandon geometry for guesswork and an equational treatment,that is the only thing that is predictable. |

Blaise Pascal I suppose you can make a living out of arguing over definitions and make a giant wordplay to substitute for a lack of intutive intelligence in geometric affairs but then again,that is what this thread is all about. |

Hi John, I already showed you that Einstein did just that in his 1905 paper when he discussed aberration. As for your question: why would such an approach highlight the differences? If you only introduce one object that is in rest, a lot of effects that should highlight the differences are 0 as well, and the speed of light relative to that aether as determined in a standard frame that is at rest in it is c according to both theories.

The notions are hilarious to behold and I am terrified that I will never find another person who finds them genuinely funny - "Now if we use a system of co-ordinates which is rigidly attached to the earth, then, relative to this system, every fixed star describes a circle of immense radius in the course of an astronomical day, a result which is opposed to the statement of the law of inertia." http://www.bartleby.com/173/4.html I guess the guy never heard of the astrological framework of Flamsteed/ Newton or that Polaris does not trace an immense circle - http://apod.nasa.gov/apod/image/0609...hambsch_f1.jpg On a serious side,the idea that there is a huge super-intellectual discussion going on between classical guys and the relativistic guys is simply a myth,Newton and his astrological framework and ballistic agenda always gets protected making this a nightmare for the rest of humanity. |
