Mountain View’s global teacher of 1,516 lessons and counting – Inside Bay Area.
From a tiny closet in Mountain View, Sal Khan is educating the globe for free.
His 1,516 videotaped mini-lectures — on topics ranging from simple addition to vector calculus and Napoleonic campaigns — are transforming the former hedge fund analyst into a YouTube sensation, reaping praise from even reluctant students across the world.
“I’m starting a virtual school for the world, teaching things the way I wanted to be taught,” explains Khan, 33, the exuberant founder and sole faculty member of the nonprofit Khan Academy, run out of his small ranch house, which he shares with his wife and infant son.
