The "Googling" videos actually seem to touch on a number of things being covered in the linear algebra and discrete math classes I'm taking. The equation in the "Maths Behind Music" video and the Lorenz curve in the "Mathematics and Social Justice" video appeared in my calculus class homework assignments.
