I'm not sure I know exactly how to use the Minkowski diagram. For
example, let's say you have a stationary observer and a moving
observer, and an event somewhere, for which the coordinates are x and
t in the stationary frame and x' and t' in the moving frame. How do
you get t', for example, from the Minkowski diagram?

Only an amateur would try to use a Minkowski diagram
(rotation diagram) to study a Lorentz transformation.
The EXPERTS use OBLIQUE COORDINATE DIAGRAMS.... you've
probaly seen these in professional publications.
The Minkowski diagram does not show "true lengths" and as
someone pointed out you CANNOT use Euclidean Geometry in the
diagram.... and it does NOT give you ture picture of the
transformation.
The EXPERTS use the LOEDEL (oblique) diagram.
Understanding this diagram is equivalent to MASTERING SR,
and it can be done in a few minutes. It turns out that the
Lorentz Transformation is IDENTICAL to the coordinate
transformation between two OBLIQUE coordinate systems... one
obtuse and the other acute. Euclidean geometry applies, the
scales are true length,... the whole thing is a miracle!
The CLASSIC text on this is SHADOWITZ'S book, which only
costs $6.95 in the ppbk Dover edition....one of the all time
best book bargains ever! DON'T LEAVE HOME WITHOUT IT!!!


SPECIAL RELATIVITY, Albert Shadowitz, 1968, Dover ppbk,
ISBN 0-486-65743-4 only $6.95 a few years ago.

By the way, you can Google the Loedel diagram but all you
get is amateur crap explanations..... for chrissakes spend
the $6.95 and buy Shadowitz'a classic book and wrap up your
studies of SR in a couple of hours!
