The manusript linked below is an introduction to special relativity that emphasizes spacetime diagrams.
Getting the Measure of Einstein's Space and Time
The following article, "The Path of an Electron Orbiting an Accelerating Nucleus" shows an alternative way to deduce the Lorentz transformation equations
using a series of "gedanken" experiments and calculations of the path of an electron around an
accelerating nucleus. The details of the calculation are shown in the Mathematica notebook listed
below the link to the manuscript.
