Sal-man Khan's voice is heard every day on the netby tens of thousands of students around the world who are hungry for help in learning math.

Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his Khan Academy" four years ago, when he taught a young cousin how to convert (转换kilograms to grams. With Khan's help, the cousin got good at math, and Khan began a new career.
