Reclaiming The American Dream VI: The (Other) Lessons of Khan Academy

Howard Husock
This article is more than 6 years old.

To say that Khan Academy has important lessons to offer is to state the obvious. The Mountain View-based internet teaching institution—which has grown from founder Salman Khan’s individualized YouTube math lessons for his 7th grade niece to a worldwide phenomenon—offers thousands of free, plain-spoken online courses, from algebra to biology. But there are even broader lessons to be taken from the astounding success of Sal Khan, winner of the Manhattan Institute’s $100,000 2014 William E. Simon Prize for Lifetime Achievement in Social Entrepreneurship. Indeed, the lessons extend well beyond education

The story of Khan Academy’s start and growth is dramatic. Sal Khan, New Orleans-born and MIT-educated, was working in the finance industry as a hedge fund analyst when, in 2004, he learned that his niece, Nadia, needed help with algebra. He began sending her his own clear, step-by-step illustrated lectures (Khan himself did not appear) via YouTube. That allowed other web users to use the same lessons. The teaching of Khan—a complete outsider to education or education reform—went viral, ultimately catching the eye of Bill Gates, whom Khan learned was helping his own children with lessons first meant for Nadia. Khan eventually attracted $15 million-plus in philanthropic support from the Bill and Melinda Gates Foundation, Google , venture capitalist John Doerr, and others accustomed to the idea that radical newcomers might be worth investing in. Such funding allowed Khan to give up his day job and start Khan Academy, with a forthright, undeniably ambitious goal: a free world-class education, for anyone, anywhere.

The first wearable computer glasses were made by Edward Thorp and Claude Shannon in 1961. In 1968, Ivan Sutherland made the "Sword of Damocles." It was the first head-mounted computer display and an early variant of all wearable computer glasses we have today. In 1980, Steve Mann, known today as the father of wearable computing, made the "WearComp", a pair of tech-enhanced glasses that was capable of communicating wirelessly with other computers and could share videos. He continued to work on the glasses over the years, and by 1999, he had come up with a pair of glasses that looked like Google Glass, or rather, that Google Glass looks like. He called it the "EyeTap."

If you thought that getting sector over- and under-weights correct at the outset proved difficult, switching between them throughout the year was nearly impossible.
