Derivation of Lorentz transformation: youtu.be/6f_yxbtM2TI

Relativity of simultaneity can be very confusing the first time you see it because it doesn't match everyday experience. However, it turns out that we need simultaneity to be relative for physics to work! Here we use linear algebra to explain why events that are simultaneous in one reference frame are not simultaneous in another reference frame.
