## Main Question or Discussion Point

This has been bothering me for a while. In Einstein's original derivation of the Lorentz transformations, he finds...

[tex]\epsilon[/tex]=[tex]\frac{c^2}{c^2-v^2}[/tex]x'

Here, [tex]\epsilon[/tex] is what we would normally call x', and x'=x-vt (sorry if that's a bit confusing). He then says, "Substituting for x' its value, we obtain"...

[tex]\epsilon[/tex]=[tex]\gamma[/tex](x-vt)

Now, am I taking crazy pills, or should that be gamma squared instead of gamma? I'm getting a similar result for the time transformation.
