t' = (t-uxcc)/sqrt(1 -uu/cc) |
The time t' > t always ,if velocity u>0
It means ,that man become older in ( x'y'z't') system ,than man in (xyzt)
system

That's tau = (t - vx/c^2) / sqrt(1-v^2/c^2) [*], but you're correct
in that all processes in the moving system will appear to slow
down (including one's broadcast frequency!) relative to you.
[*] the traditional symbol for velocity is v;
tau is a greek letter, not a product;
c^2 = c * c (or, in your notation, cc).

Hi
The hands of clock goes more quickly in (x'y'z't') system,than in (xyzt)
system..
Sincerelly yours E.W.

Depends on who's observing it. As far as observer A goes, B's
clock is running slow. B can say the same regarding A's clock.
The transformation is as follows.
xi = (x - vt) / sqrt(1-v^2/c^2)
tau = (t - vx/c^2) / sqrt(1-v^2/c^2)
If one computes the following, where g = 1/sqrt(1-v^2/c^2) for brevity:
xi + v * tau = (x - v*t)*g + v*(t - vx/c^2)*g
= x*g - v*t*g + v*t*g - v^2*x*g/c^2
= x*g*(1 - v^2/c^2)
= x/g
tau + v * xi / c^2 = (t - v*x/c^2)*g + v*g*(x-v*t)/c^2
= t*g - v*x*g/c^2 + v*g*x/c^2 - v^2*g*t/c^2
= t*g*(1-v^2/c^2)
= t/g
then one immediately sees that
x = (xi + v*tau) / sqrt(1-v^2/c^2)
t = (tau + v*xi/c^2) / sqrt(1-v^2/c^2)
which is exactly what one should get.
So both of them would say "Hey, your clock is the one that's slow!" :-)
