Are there any good youtube videos out there that explain at a conceptual level some of the foundational fields of math? Without going into how specific problems are solved, but more a general overview of what integrals *are*, for instance, and what they look like. Not strategies to actually do the math or legitimate teaching aids.
Basically, I want to be able to intelligently answer my boomer parents who never got past Algebra I when they ask what I'm doing in my complex analysis course.
