HAHAHA!
Elementary linear algebra and calculus:
"2AB/(t'A-tA) = c" -- Einstein.
Light travels from A to A in time t'A-tA = 0/0.
The first thing to learn is not to divide by zero.
An error in Relativity "would be like Stephen Hawking dividing by zero or
something equally trivial." -- Bielawski.
ROFLMAO!

" kk's postings about physical content of Einstein's postulates made me
look again at his 1905 paper and I noticed what I think is another
experimental assumption.
Recall Einstein's definition of synchronisation of two clocks A and B:
send a light pulse from A to B, reflect the light at B back to A,
register the emmission and the arrival times: t_A, t_B, and t'_A. The
clocks A and B are synchronised if:
t_B - t_A = t'_A - t_B (*)
(Equivalently, one can send two light rays, from A to B and from B to A
and then the requirement is that:
t_B - t_A = t'_A - t'_B, (**)
where t'_B is the second ray's emission time at B.)
He then says: "We assume that this definition of synchronism is free
from contradictions" and notes that the following two conditions are
satisfied (thus guaranteeing the "freedom from contradictions"):
"1. If the clock at B synchronizes with the clock at A, the clock at
A synchronizes with the clock at B.
2. If the clock at A synchronizes with the clock at B and also with
the clock at C, the clocks at B and C also synchronize with each
other."
This portion of the 1905 paper is frequently glossed over (I've never
seen it discussed on this NG) but the second condition is in fact
non-trivial and it demands that certain experiment yield certain
result. Otherwise Einstein's synchronisation of clocks is vacuous.
Try to prove condition 2 yourself: sync clock at A with clock at B
(condition (*) or (**) satisfied), and also clock at A with clock at C
(ditto), and based on this try to prove that B is in sync with C
(again, this means that (*) or (**) must hold for B and C). While doing
this remember that A, B, C are in 3D space, i.e., not necessarily
colinear.
You'll see you cannot prove it unless you know that the following is
also true: the time it takes for a light ray to complete a triangular
roundtrip A-B-C-A equals the time it takes for a light ray to complete
the reverse triangular trip: A-C-B-A (imagine mirrors positioned at B
and C to make the light ray go around). This must be verified
experimentally, otherwise there is a chance the definition of Einstein
sync is vacuous. "
HAHAHAHA!!!
