Learning aboutTensor Calculus

In early physics training coordinates are most likely grounded in intuition and common sense. But when the spacetime you are trying to describe twists and turns such that any coordinate system will eventually fail, it is time to take a detailed look at the logic and consequences of coordinate systems in general. Associate Professor Pavel Grinfeld does this very well, with a level of rigour suited to physics.
