"If I am to have faults, I would rather they be my own." Vi Hart
Vi Hart is somewhat critical of math teachers in this video, and of systems which prevent exploration into mathematics in their desire to ensure that all students have equal exposure to mathematical ideas. Of course, as she points out, students rarely have exposure to mathematical ideas. Instead, what they usually experience are mathematical procedures to solve problems that aren't their own.
