Talk:On the Electrodynamics of Moving Bodies
I was just going through this paper "On the Electrodynamics of Moving Bodies", and in heading 3, which is "Theory of Co-ordinate and Time-Transformation from a stationary system to a system which moves relatively to this with uniform velocity.", I didn't understand the substituition x' = x-vt. First of all, the system in which x',y and z are independent of time is the k system, which is moving at a constant velocity w.r.t. K. But there it has been given otherwise. Also, if we are using x' = x-vt, aren't we going back to the Galilean transformations? But the purpose of this paper was to show that the Galilean transformation are not exactly correct, then why does it start from there?
longitudinal mass? 
Was the "translator" overly eager to add square roots, or is the erroneous equation for longitudinal mass in section 10 a wiki error? 126.96.36.199 23:29, 8 August 2010 (UTC)
