The Maths of General Relativity (2/8) – Spacetime velocity

In this series, we build together the theory of general relativity. This second video focuses on the notions of velocity, vector components, and we write down our very first equation.

0:00 – Velocity vector
1:09 – The speed of light
1:40 – c = 1
2:13 – Velocity coordinates
3:28 – The Einstein notation
4:29 – Concrete example
