That is that clock B > is ticking *SLOWER* than clocks in A Right....SR predicts that the passage of an interval of clock time on the B clock corresponds to the passage of a lesser interval of clock time on the A clock....that means that the B clock is running slower than the A clock. Delta(T_B)=gamma[Delta(T_A)] The problem is: Sr predicts the same for an observer on B. > > Now lets have a second gedanken. > > In this case we have a single clock A at rest in your frame, and two > co-moving moving clocks (B1, B2 say) that are synchronised in their own > frame and are moving past A (with the same speed as B in the previous > experiment) Why is B1 and B2 moving past A...why not A moving past B1 and B2 ??? > > AS in the previous experiment, clock A takes a set of two readings, one of > its own time, and the other of the time shown on the moving clock. > > So we get two sets of readings from A .. one set when B1 passes and another > set when B2 passes.

This is wrong....B is the observer and B1 and B2 are in sych in the B frame. Therefore B must predict that A is running fast as follows: Delta(T_A)=Delta(T_B)/gamma Ken Seto > > As the previous experiment shows that a moving clock, B, is measured as > ticking slower .. that must mean that the second interpretation (that moving > clocks are NOT in sync in your frame) is the correct one.

I just popped more popcorn.

Geez, you've been kooking in here for 15 years now but still don't understand the basic fundamentals of relativity? All inertial frames in SR have the same math, so of course an observer in A's frame can do measurements with B1 and B2 moving past A by assuming A is stationary. >> AS in the previous experiment, clock A takes a set of two readings, one of >> its own time, and the other of the time shown on the moving clock. >> >> So we get two sets of readings from A .. one set when B1 passes and another >> set when B2 passes. >So you are assuming that the B clocks are doing the moving while A >remains stationary....right? All motion is relative, so of course A will see the B clocks as moving. (and yes, an observer in B will see the A clocks as moving, but that was already discussed as the first gedanken, so it's not relevant here) You got to keep the A and B frames separate. This is where you always get mixed up. >> If you compare them, you'll find, in this case, a *longer* elapsed time >> between B1 and B2 than is shown on A (the opposite results to the previous >> experiment) >This is a bogus assumption based on the faulty SR math that all clocks >moving wrt the observer (A or B) are running slow. No, just do the logic that was just shown to you! >> How can this be? >> >> The result of the second experiment implies that either clocks B1 and B2 >> were in sync in your frame but ticking *FASTER* -- OR -- that the clocks are >> *NOT* in sync in your frame. >This is wrong....B is the observer and B1 and B2 are in sych in the B >frame. But not the A frame. And that is the point.

For the record, Koobee Wublee was explaining how the Lorentz transform actually predicts both blue and red shift at the same time. See the post below. http://groups.google.com/group/sci.physics.relativity/msg/c4d248370bde9eee?hl=en Suddenly, professor Andersen, out of the blue, changed the discussion with this post without addressing Koobee Wublees previous post. http://groups.google.com/group/sci.physics.relativity/msg/077983367e3fe36a?hl=en Koobee Wublee, an ever so humble, good Samaritan, answered professor Andersens questions fair and square. The good hearted Koobee Wublee saw the same mistakes and garbage that professor Andersen had defecated all over these newsgroups in the past few years and decided not to press any further charges. See the post below. http://groups.google.com/group/sci.physics.relativity/msg/59b3d0dcb8deab2d?hl=en Seeing himself checkmated once again, professor Andersen decided to behave childish and defiant with the following useless post. http://groups.google.com/group/sci.physics.relativity/msg/29d192787e693974?hl=en The good hearted and ever so humble Koobee Wublee tried once again to reach out to save professor Andersen from drowning in his cesspool of fermented diarrhea of Einstein the nitwit, the plagiarist, and the liar with the following post. In doing so, Koobee Wublee even showed professor Andersen what a mathematical model of Doppler effect would look like and guided with hints on how to arrive with that. http://groups.google.com/group/sci.physics.relativity/msg/22d990f50ede9754?hl=en The asinine professor Andersen then refused to discuss any further by repeating the same bullshit from the very beginning. Professor Andersen is indeed a very small man. <shrug> |
