Introduction to the Special Theory of Relativity - Lesson 25.1

Explore Einstein's Special Theory of Relativity in this 16-minute introductory video. Delve into the two fundamental postulates: the universality of physical laws in inertial frames and the constancy of light speed in vacuum. Understand the concept of inertial frames and their relation to Newton's First Law of Motion. Examine the implications of constant light speed across all inertial frames, leading to frame-dependent measurements of time and distance at high velocities. Review classical relative motion before investigating the relativistic consequences of constant light speed. Gain a solid foundation in this groundbreaking theory that revolutionized our understanding of space, time, and motion.
