You probably wouldn't recognize his face, but Sal Kahn's voice is known by countless students.
Kahn founded the "Khan Academy" three years ago with video tutorials on a wide variety of subjects, including photosynthesis, calculus, the Bay of Pigs invasion and more. He has a knack for breaking down and explaining tough topics. Approximately 6 million students view the videos each month, and Khan is changing the way we teach kids.
He's going to be speaking at the Wall Street Journal's "All Things Digital" tech conference taking place in California today. He talks to Soledad on "Starting Point" this morning to talk about how his technique is revolutionizing education, and not just for kids.
Starting Point airs weekdays from 7am to 9am ET on CNN. Check in often to join the daily conversation.
