Physics - Special Theory of Relativity

Course Description

This is a half a semester (20 Lecture) course on Special Theory of Relativity, which revolutionized our concept of physics in the last century by unifying concept of space and time, electricity and magnetism and mass and energy. In this course we will explore and explain many of the (often) counter-intuitive but fundamental principles of the Special Theory. Faculty Prof. Shiva Prasad IIT Bombay Courtesy: NPTEL HRD
