The Maths of General Relativity (4/8) – Metric tensor

In this series, we build together the theory of general relativity. This fourth video focuses on the notion of metric tensor, its relations to the Christoffel symbols, and physical distances.

0:00 – The metric tensor
3:45 – Relating abstraction to geometry
4:25 – Calculating Christoffel symbols from the metric
6:44 – From the metric to trajectories
7:39 – Concrete example 1
9:35 – Concrete example 2 – The Minkowski metric
