Modern Physics 5-4: The Lorentz Transformation
Channel: Mark Ancliff
Date: 06/02/2017

These videos are taken from a lecture course on Modern Physics I taught at the Catholic University of Korea in Spring 2016.

In this class we use the combined effects of length contraction, time dilation and relative simultaneity calculated in the previous video to derive a new coordinate transformation (of space and time) between inertial observers. This is known as the Lorentz transformation (which as far as we can tell is exact) and replaces the Galilean transformation (which is a good approximation only at speeds much less than the speed of light).
