Chapter 1: Why Relativity is Hard https://www.youtube.com/watch?v=1rLWVZVWfdY&

Chapter 3: Lorentz Transformations https://www.youtube.com/watch?v=Rh0pYtQG5wI

This video is chapter 4 in my series on special relativity, and it covers how things that appear simultaneous from one perspective in our universe aren’t simultaneous from other moving perspectives – that is, from inertial reference frames moving at different speeds. This is explained via the Lorentz transformation of coordinates of the events in question, enacted with a mechanical minkowski diagram, aka mechanical Lorentz transformation, aka spacetime globe.
