Special Relativity: Crash Course Physics

The video explains special relativity using a hypothetical train scenario. It introduces the concept of inertial reference frames and discusses the two main postulates: the constancy of the speed of light and the uniformity of physical laws across frames. The video explores time dilation and length contraction, illustrating how time and distance change for observers in different frames. It also covers the lack of universal simultaneity and the concept of four-dimensional space-time, emphasizing the counterintuitive nature of these phenomena at high speeds.
