Relativity Using Spacetime Diagrams | Time Dilation & Length Contraction

How to use (Minkowski) SPACE TIME DIAGRAMS to prove - Time Dilation | Length Contraction | Relativistic Velocity Additions, etc?

In this video lecture, I show how simply we can demonstrate the consequences of Special theory of relativity using space time geometry calculations.

00:00 Introduction
01:50 Relativity of Simultaneous Events
09:42 Time Dilation
21:18 Length Contraction
37:11 Relativistic Addition of Velocities
