Cartesian Tensor Calculus of Euclidean Metric Spaces: Ep. 3 - Metric Tensors and Einstein Summation

In this video, I introduce Euclidean metric tensors and begin taking off with the mathematics by introducing the Einstein summation convention.

Edit: On the third example under "Other Examples" as well as Practice Problem 5, I meant to say "Contravariant tensor" instead of covariant tensor.
