What is the Special Theory of Relativity? What were the motivations of Einstein to lay down his postulates?In this video, I do a brief summary of the history of Galilean invariance, Maxwell's Equations and how Albert Einstein connected all the dots to present his two posthulates.

The Special Theory of Relativity or STR is a ground breaking theory of Physics. It makes certain predictions about the nature of space and time that have far reaching consequences. To name a few: Length contraction, Time Dilation, Relativity of Simultaneity, Relativistic Mass, the famous E=MC^2 and so on

But how did all this come about?
I discuss all this in this video lecture.
