Geometry and Relativity (Part 17)

A bit more about the hyperbolic function description of Lorentz transformations, and a derivation of the Doppler shift formula.

thanks for the videos. they are really great. towards the end here, you seem to reverse some signs for the Z, after v' = Z*v.

you use z = sqrt( (1-v)/(1+v) ). I think this ought to be z = sqrt( (1+ v)/(1 - v) ), as was demonstrated at the end of the last video. Correct?

thanks again!
