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

Описание: 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!

My blog is at http://njwildberger.com/, where I will discuss lots of foundational issues, along with other things.

Online courses will be developed at openlearning.com. The first one, already underway is Algebraic Calculus One at https://www.openlearning.com/courses/... Please join us for an exciting new approach to one of mathematics' most important subjects!
