## Main Question or Discussion Point

Hi,

I don't fully understand the derivation of the Lorentz Transform.

For example, in the transformation:

[tex]t' = \gamma t - \gamma\frac{vx}{c^2}[/tex]

Where do you get the x-term from? I understand the derivation of gamma, and I see that when x = 0 (when the two frames coincide in origin) the tranformation is just gamma * t, but I don't understand how you derive the x-term. I've checked out numerous sites and these sites don't give a derivation for the equation for t'.

The x-term looks suspiciously like the time it takes to time the light's trip but that's not the way of thinking of special relativity, so far as I know...

Basically, I'm looking for (A) the x-term in the t' transformation equation and (B) the derivation of the Lorentz transform for motion in the x-direction.

Thanks in advance.
