<p>Grahame,</p>
<p>so as you have explained 'reciprocity' here, it is also my
understanding. <br>
</p>
<p>Sorry, I missed your book. Can you please give me a reference (if
it is in the internet) or the exact title and editor, if it is
only available as a hard copy?</p>
<p>One question in advance: Does the book also cover GRT? And if
this is the case, is it also based on a fixed frame, so that it
assumes something like an ether? <br>
</p>
<p>Best regards<br>
Albrecht<br>

all that you say here. I'd add just one reminder, of what
we've talked about before.</font></div>

<div><font size="2" face="Arial" color="#000080">For the 'unique
absolute rest frame' to fully stand up to scrutiny in the
light of experimental findings of SR, it's not only necessary
to show that an observer in a moving frame would be led to
believe from observation that their frame is static - it's
also necessary to show that this moving observer would
perceive the SAME degree of (a) time dilation and (b) length
contraction in the absolutely static frame as would be seen
from that static frame in the observer's frame (those two
effects are of course NOT objective realities in the static
frame, they are perceived by the moving observer as a
consequence of their OWN motion).</font></div>
<div> </div>
<div><font size="2" face="Arial" color="#000080">To show that the
moving observer perceives themself as static is relatively
(!!) easy; to show that they perceive an actually-static frame
as subject to relativistic effects takes a little more thought
- but it can be done, and shown to be so. [This is what I
have referred to previously as 'reciprocity'.]</font></div>
<div> </div>
<div><font size="2" face="Arial" color="#000080">In addition, of
course, it needs to be - and CAN be - shown how EVERY
experimental finding that's considered to be evidence for
frame symmetry can be fully explained without any need for, or
reference to, frame symmetry.</font></div>

just a little more thought than most physicists appear to have

explaining the 'how'?)</font></div>

<p>Chip,</p>

<p>I also think that it is the easiest and most physical way to
understand relativity in general and dilation in particular,
if one assumes that there is an absolute frame of rest, and
that the motion with respect to this frame causes (among other
phenomena) dilation. But it is a specific property of
relativity that every observer in any inertial frame can
assume that his frame is the frame at rest. And in his
observation the physical world behaves indeed as if his frame
would be the absolute frame at rest.</p>
<p><br>
</p>
<p>This sounds like a paradox at the first glance. But with a
proper use of the Lorentz transformation it can be explained
why it is this way. It is a bit of work to make these
calculations, but it is possible and one may say that this
work is a necessity to understand special relativity.</p>
