nicely put MacM.Members,
Since James either cannot address this issue or chooses to dodge it let me clarify what we are looking at.
James R's continued arguement is very much like an affect we have all experienced.
That is a train whistle. As it approaches it sounds "Weeeee"
and as it passes and begins to receed it sounds "Oooooooooh."
The approaching sound has a higher pitch because as the train approaches each sound wave arrives sooner because the distance to travel is less than it would have been if the vehicle were sitting at rest relative to you.
When it receeds each sound wave now takes longer to reach you because distance is steadily increasing.
So the affect is to increase and decrease frequency or pitch from your frame of reference.
If you now count each sound wave using an on board counter.
Mark off an equal distance east and west of your location.
Have two trains with calibrated and synchronized whistles.
One train remains at rest and the other moves at 0.6c approaching from the east.
As the train passes the east marker it and the resting train begin to count sound waves and transmits a digital total count as it passes your location.
If the resting train transmits a count of 30,000 pulses. The traveling train will transmit a digital count of only 24,000 pulses.
The traveling train and resting train both reset their counters and as the traveling train receeds they both continue to count until the traveling train passes the west marker.
It then will transmit a digital total count of 24,000 counts and the resting train will have recorded 30,000 counts.
The synchronizaton is done any number of ways; including light signals and computing time delay of signals to and from respective frames with adjustments to the counts accordingly.
So the change in pitch to you is an "Illusion of motion" and did not affect the actual frequency of the whistle.
The "Perception" by observers that frequency is changing (speeding up and slowing down with vector of motion) and physical count results are two different issues.
In this example the wistle count represents time ticks.
The "Illusion of motion" of changing frequency does not have any bearing on the physical reality of time dilation of an accelerated frame.
It is equally important to note that while both the resting and traveling observer will experience the shift in frequency of respective whistles as they approach and pass, it is MORE important to understand that the digital information does not include reciprocity.
That is any prediction that both actually physcially tick slower is falsified. Because the traveling train is notified that the resting train had 30,000 counts to his 24,000 counts. So the view in SR is only valid physically for the traveling train which is what is supported by emeprical data.
The suggestion that the approaching clock increases tick rate to match a previous rest frame after having slowed due to having accelerated away is not supported since an inertial condition at turn around would create a new rest reference and the return flight is decreasing tick rate from that frame.
Clocks cannot and do not both physically increase and decrease tick rates simulatenously. They can "Appear" to do so but naot actually do so. The digital count of both frames is physical reality in both frames.
Sorry James R. Back to the drawing board.
and pretty damn good for something Sciforums deems worthy of the cesspool....what an embarrassment....[for them ha]
