His little lessons changed his life – and many others’, too

THE PRINCIPLE

It doesn’t take high-tech or a big team to change the world

In 2006 Sal Kahn worked in finance, so he was the logical person for his young cousins to turn to when they had problems learning science and maths. He started making YouTube videos to tutor them remotely.

His relatives weren’t the only ones who found his lessons useful. Six years later, he’s posted more than 2600 micro-lessons and his work has come to be known as the Khan Academy. It’s now his full-time job and the videos have been seen more than 67 million times.

The tutorials, which cover mathematics, finance, history, physics, chemistry, biology, astronomy, computer science and economics, are free, supported by donations and underwriting from foundations. In 2010 Google announced a grant of $2 million to support the creation of more courses and to translate the Academy’s content into more languages.

By the way, Khan’s face never appears in the videos, they’re all done with illustrations, diagrams and screen captures.

From a few mini-lessons for his relatives, Khan has gone to the goal of creating ‘the world’s first free, world-class virtual school where anyone can learn anything’.
