Exactly. Vi isn't a teacher, either. Khan hired her to continue doing what she's been doing for quite some time: Make math inspirational and interesting. She didn't even take any math courses at university. She's just incredibly passionate about its odd applications.

I know more than a few artists who self-describe as math haters who changed their tune (if only briefly) and searched their souls for the true meaning of shapes after seeing a few of Vi's wonderful videos.
