Hey, I'm just learning the ins and outs of special relativity and I'm having a little trouble with the derivation of the Lorentz Transformation. I bought Einstein's book 'Relativity: the special and general theories' and this is described in an appendix. For background, the appendix is linked to at the bottom of this post. (It was posted on marxists.org, I found that pretty funny, even though I knew Einstein was a socialist.) I get lost between(adsbygoogle = window.adsbygoogle || []).push({});

(x'+ct')=μ(x+ct) and

a=(λ+μ)/2

Also, looking ahead, I've gotten lost before (this isn't my first time looking over the appendix, I lost my work from last time, though) between

dx=1/a

and x'=a(1-(v2)/c^2))x <-- this one I really can't get (how does he get there?)

If anyone could be of any help, thanks!
