"Gregory L. Hansen" wrote in message ... In article , eleaticus wrote: "David McAnally" wrote in message ... The transformation law for the differential operators under the Galilean transformation is given by: d/dt' = d/dt + v d/dx, Tell us how there can be a d/dt' when there is no t'? When the Newton-theoretical lack of a time transform is honored when treating Newton-theoretical transforms, which are the subject matter in discussion? eleaticus In general, a transform has x'(x,y,z,t), y'(x,y,z,t), z'(x,y,z,t), t'(x,y,z,t). That is, each new coordinate is a function of all of the old coordinates. In a typical Newtonian transformation we have t'=t, but that's a special case. In the most prosaic Newtonian time transformation, we simply add an offset to put t'=0 somewhere convenient, t'=t-t0. Or we could scale the coordinate to go to a different time standard with a different rate of ticking, t'=kt. Less prosaically, stick with a universal time and transform to a frame rotating with angular velocity w relative to the stationary frame. Then we have, for a vector V, dV/dt' = dV/dt + w cross V See Goldstein, chapter 4. Thanks for the post Hansen, but it misses the point, perhaps because you missed posts here. In Newtonian terms there is no time transform, so acting as if there were has no functional purpose but to introduce a spurious new variable with which to decide that a Newtonian-theoretical transform is not invariant. On the other hand, velocity v definitely is not invariant under the transformations; it is relative to one of the coordinate systems. L = x0 + ut. x0 becomes x0-vt and ut becomes (v-u) in the second system. Yet, y'all do not include v in your list of transformations and xform-based operators. Why? The only excuse is that it is not a transformed coordinate and it is transformed coordinates under discussion. Just so, under the Newtonian premise time is absolute, there is no time transform, and there is no reason outside of obstinate insistence on doing it in a way that reaches a dogmatic conclusion by pretending there is a time transform. t=t in all systems. Just what is so hard about giving poor old Newton his 'props'? Why is it so hard to give him his premise when discussing something based on his premise? You KNOW that the operators McAnally (et al) give are not based on giving Newton his premise. You KNOW they are demonstrably not the operators you would derive without the spurious t'=t. If you are truly honest and interested in truth, you can show McAnally/etc that as fact. Show us all the operators that ensue from giving Newton his premise. eleaticus -- "What are the possibilities of small but movable machines? They may or may not be useful, but they surely would be fun to make." -- Richard P. Feynman, 1959 |

"robert j. kolker" wrote in message ... eleaticus wrote: He says there is a time transform under Newton, I say there isn't. You agree with me and insult me for it? It is the -identity- transform, stupid. No, it is not, idiot. The identity transform is t=t which introduces no spurious terms into the analysis. If you weren't too stupid and ignorant I'd suggest you devise the transformation operators using the actual identity transform so you could see that there is a tremendous difference. But, alas, you are both too stupid and too ignorant so ... sigh. eleaticus Bob Kolker |

"Uncle Al" wrote in message ... Newton was empirically wrong, you empirical idiot. Hey stooopid - tell us the GPS system does not work. To quote myself: Focus well on negative 'responses'. Are they vicious ranting? Are the replies actually responsive? Do they rant about gravity, or how Relativity is proved correct a million times each day, or some other 'we are proved right' rave that doesn't deal in details about the debunking done here? It is typically General Relativity or items about the energy and mass of moving objects that are being waved at you, and such items are completely irrelevant to coordinate transformations and invariance.. Just ask them for a list of all the observations that have been made of the shortening (contraction) of moving objects that Special Relativity says always occurs. eleaticus |
