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

For the fourth year in a row, the top five places continue to be dominated by the same five intercontinental EMBAs. Tiemba came top this year not by spectacularly outperforming its rivals but thanks to a strong performance across most indicators. In particular, the alumni have the second highest salary on average ($324,000) behind alumni from the Kellogg/HKUST programme ($408,000). Tiemba is also ranked second for career progression and fourth for work experience.

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.

Skin has the thankless job of coating and protecting your whole body, making it your most easily damaged organ. When you burn or rip off a stretch of skin, your main option right now is to graft some back on from elsewhere on your body. But an effective synthetic replacement skin may not be that far off, thanks to research from Stanford scientists.

'I thought I was going to sell the app in the Apple store for a pound or two each, and then I'd use the money to buy a new computer,' says D'Aloisio. 'I'd never had any contact from an investor before. And now here's an email supposedly from a Hong Kong billionaire. It sounded dodgy. I didn't respond the first time. They had to email me again.' D'Aloisio was accompanied by his mother and father ('they were a bit bewildered, it was kind of insane') as he took a meeting with Horizons Ventures's representatives in London in August 2011. The meeting ended with D'Aloisio receiving a seed investment of $300,000.

Like any college kid, Evan Wray loved using the tiny pictograms known as emoji. But he hated that there was no emoji to express his Fighting Irish pride with fellow University of Notre Dame students. So, alongside co-founder Sean O’Brien, he built a modest business on that disconnect. TextPride, as it was called, licensed images from brands in the sports and entertainment world and sold them as sticker packs. Within a messaging app like Kik, users could buy a packet of stickers for Disney’s Frozen for $1.99, for example.

Jonathan Glazer’s Under the Skin is a film about a beautiful, scary alien that is itself beautiful and scary and alien: it’s an entirely extraordinary, outrageously sensual film that Glazer’s previous excellent work had really only hinted at, partially and indistinctly. His Sexy Beast (2000) was a visually accomplished, exciting and intelligent crime thriller that was way ahead of the woeful mockney-geezer mode of the time. Birth (2004) had Kubrickian ingenuity and chill, with some remarkable moments; it was a movie that deserves cult-classic status but has yet to achieve it. Then a decade went by, and it seemed that Glazer might be a stylist for whom a sustained cinema career would perhaps not be achievable (and heaven knows, it can happen to the most talented).
