<p>Wolf,</p>
<p>I have never denied that there is a difference between our
perception and a (possible) reality. What I always have said is
that this assumption does not help us in our attempt to understand
the world around us unless we understand the difference between
reality and our perception functionally, or at least investigate
our detectable errors in a <i>quantitative </i>way.</p>
<p>This last discussion about the important question in relativity,
whether there is a frame at absolute rest, can easily be treated
if using the Lorentz Transformation. This L.T. shows us <i>quantitatively</i>,
in which way the results of measurements are influenced by
relativistic effects so that this impression of a frame at rest is
caused in any frame; and our perception reacts similar to the
measurement tools.</p>
<p>This was content of the discussion between Grahame and me.<br>
</p>
<p>And using your example of dilation: this dilation is a physical
fact in the frame at rest; but it is only perception in a frame
not at rest by the effect of relativistic synchronization, where
the way of synchronization is quantitatively given by the Lorentz
Transformation. <br>

<p>I think you are saying something that I have been trying to
make clear to Albrecht which derives from my attempt to move
physics away from the Aristotelian belief that we see reality
through the windows of our senses and employ the Platonic belief
that we see the 'shadows" - in modern therms- we see our
interpretation of the measurement reports from our sensors - in
this case our body built in coordinate frame. I then translate
your statements into more anthropomorphic observer inclusive
language using larger font than your comments, <br>

<p>so as you have explained 'reciprocity' here, it is also my

<p>One question in advance: Does the book also cover GRT? And if

<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>
