Have you found the difference between xi and x' yet, local village idiot?
Androcles


x' = phi(-v)*beta(-v)*(xi + v*tau)
where beta(v) = 1/sqrt(1-v^2/c^2)

Since phi(-v) = 1,
x' = beta(-v)*(xi + v*tau) = (xi + v*tau)/sqrt(1-v^2/c^2)

therefore
xi - x' = xi - (xi + v*tau)/sqrt(1-v^2/c^2) .

http://www.fourmilab.ch/etexts/einstein/specrel/www/

Since tau is a free variable no conclusions can be drawn regarding
whether xi < x', xi > x', or xi = x'.

Note that there is a minor error in the paper, since x' is defined twice
in section 3; an alternate answer to your question is therefore

xi - (x - vt) = xi - x + vt

and we still can draw no conclusions about the relative ordering of x'
and xi.

Does this answer your question? :-)
