The Exterior Algebra (Clifford/Geometric Algebra)

This video gives a decent introduction to the exterior algebra. It reviews the universal problem it solves, lays out the construction functor, shows how this functor can be seen as a left adjoint, gets into its structure as an N-graded commutative algebra, discuss the universal problem solved by the degree k parts, and even gets to defining the determinant of a linear endomorphim. A solid background before getting into GA/Clifford Algebra more properly.
