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

There were reversals too. Sales of electric vehicles suffered as gas prices leveled off and then fell. Suzuki wound down its presence in the U.S. market, and Volvo looked none too healthy.

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.

In 2010, the Martin Aircraft Company introduced a jetpack it called "the world's first piratical jetpack." The jetpack even won a spot in Time's Top 50 Inventions of 2010. While its development has been on since 1981, the world's first jetpack is known to have flown in 1958. It was designed by Wendell Moore, a researcher at Bells Aerosystems. Early prototypes of Wendell's jetpack could reach a height of 5 meters (16 ft) and remain airborne for three minutes. This attracted the attention of the US Army, which funded the project with $150,000. Several test flights were later done for the US Army and even for JFK himself. The army later stopped paying for more research into the project because the flight time and distance were not convincing enough. NASA also wanted to use the jetpack for their Apollo 11 mission to serve as backups in case their lunar module malfunctioned. They later changed their minds, going for the lunar rover instead. After this setback, Bell discontinued further research on the jetpack.
