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 are always one or two coworkers in the office that most people can't stand. But if you don't like most of your coworkers, chances are your days aren't very enjoyable because you have to work with them day in and day out. If you can't stand most of your coworkers, it's time to think about finding a company whose employees you mesh with better.

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.

Logan's claws are slow on the draw and his self-healing powers are on the fritz, but he's committed to caring for his mentor Charles Xavier (Patrick Stewart, so good you want to applaud). It's not easy watching Professor X suffer seizures that rattle his telepathic brain. Make no mistake, Logan earns its tears. If Jackman and Stewart are serious about this being their mutual X-Men swan song, they could not have crafted a more heartfelt valedictory.

?Bond has it all and that's exactly what the most beautiful women demand in the men they date. Women who really enjoy sex prefer "bad boys" -- and there's no doubt 007 qualifies.

One of the best James Bond theme songs wasn't actually played over the opening credits, so we're giving it our first honorable mention. This enormously romantic song from On Her Majesty's Secret Service is one of the few James Bond themes that helps tell the story of the film, in which our hero finally meets the love of his life. (Alas, it was short-lived.) Satchmo warbles his trademark warble, our hearts melt, and a classic is born.
Ultimately I expect these new leaders to start selecting from a broader pool of candidates and appoint direct reports from more varied backgrounds, defying those who use current imbalances to extrapolate gloomily that leadership parity between men and women is still decades off.

Fund shareholders weren’t wasting any time reacting to this year of disappointment. Collectively, they’ve added just $35 billion to active stock-picking funds in the last 11 months, less than a quarter of the $162 billion they added in 2013, which was the first year of positive flows for the industry since 2007. This is not to say that they were sitting still. ETFs and passive index funds took in over $206 billion in net deposits through Thanksgiving, and Vanguard surpassed the $3 trillion mark sometime in late summer. Investors seem to have decided that they’d rather bet on the horses than the jockeys, after all.

"We are quite interested in looking at China's efforts and experience in combating corruption. It's a problem we are faced with in South Africa, and one we are tackling with a lot of vigor.Recently, the South African government introduced new measures to combat corruption. This is interesting, because it was immediately after a visit by our minister for public services, who met with the minister here who is responsible for anti-corruption measures.So this is one of the examples of the usefulness of this interaction between our leadership and the leadership of the People's Republic of China."

“Selling out!” “Pandering to the Americans!” The cries went up immediately when the official selection was announced. The list of directors crossing over to make films in English was a long one including the Italians Matteo Garrone and Paolo Sorrentino, Yorgos Lanthimos of Greece, Norway's Joachim Trier and even Guillaume Nicloux of France, a country whose cultural establishment is highly sensitive to the creeping Anglophone menace. The argument goes that Cannes is supposed to be a haven for world cinema; for English, there is Hollywood. But does it really matter? Films at Cannes in languages other than French or English play with subtitles in both languages – and that's a lot of text to deal with.
