An elementary introduction to Special Relativity I | Wild Linear Algebra B 37 | NJ Wildberger

We give a non-standard introduction to the basic framework of Einstein’s Special theory of Relativity (SR), which avoids various assumptions that are usually introduced (often without either explanation or justification). We show that SR is a consequence of simple Newtonian mechanics when we replace the idea of an inertial frame with the idea of an inertial observer.

The discussion is introduced via a one-dimensional Newtonian situation involving bats using echo location to detect events!
