Spacetime Intervals: Not EVERYTHING is Relative | Special Relativity Ch. 7

The video tutorial explores the concept of relativity, emphasizing how perceptions of lengths, distances, and time intervals vary from different perspectives. It introduces the space-time Pythagorean theorem, which allows for consistent measurement of true lengths and durations, known as proper length and proper time. The tutorial explains time dilation and how space-time intervals can be calculated using Lorenz transformations, providing a universal understanding of measurements across different frames of reference.

How does the space-time version of the Pythagorean theorem differ from the regular Pythagorean theorem?
