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

You might think that our love of lists could be pinned on the Ten Commandments, but Umberto Eco says otherwise. “The list is the origin of the culture,” he once said on a subject he knows well, having written a book titled “The Infinity of Lists.” And culture wants “to make infinity comprehensible” and “to create order — not always, but often,” hence Homer’s catalogs in “The Iliad” and the roll call of never-completed household chores on my fridge. “We like lists because we don’t want to die,” Mr. Eco also said, which is the best explanation of the listicle that I’ve yet read.

FOYLE’S WAR (acorn.tv, Feb. 2) After nabbing the final three episodes of “Agatha Christie’s Poirot” last year, the streaming service Acorn TV scores another coup in the field of traditional British mysteries with the American premiere of this superior show’s ninth season. Starring Michael Kitchen as Christopher Foyle, a detective as honorable as he is shrewd, the series has morphed over the years from a provincial home-front cop show to a le Carré-like Cold War thriller. New episodes involve the Nuremberg trials and Britain’s role in Palestine.

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.

No. One way it could play out: after a tentative start involving lots of trading stops, bitcoin futures will slowly begin to attract institutional money. Commodity Futures Trading Commission positioning data will reflect the extraordinary long bias that exists for the product among money managers. As the huge cost of rolling futures positions becomes self-evident, longs will complain ever more loudly about routine divergences around settlement time. Just as a senate hearing is being scheduled to investigate potential manipulation of the market, futures prices will fall below spot, initiating a sell-off.

本地社交媒体广告,即那些恰好出现在你的Twitter和Facebook信息流之中的广告,在2013年爆炸式增长。2014年,无论你爱也好,恨也罢,这类广告的规模只会变得越来越大。,尽管听起来有点让人毛骨悚然,但特定位置定位技术预计将在来年出现显著改进。Twitter刚刚推出了一项面向特定邮政编码区域发送有偿消息的功能。比如,当你走进一个社区,当地酒吧、干洗店和麦当劳(McDonald's)发布的“推广消息”就会突然闪现在你的Twitter信息流之中。自2011年来,Facebook一直在采用这种“地理围栏”技术。它能够让商家招揽临近的客户,这些客户实际上可能也想获得提供特别优惠和特价商品的广告信息。好处是,你可以获得更多相关的广告和推销信息。缺点同样是,更多的广告。

The result was a loss of playoff revenue so steep that it actually hurt the cap situation of teams trying to find room to compete with the Warriors. The Finals were supposed to be the last hope, the last chance, and there were those who foolishly kept telling you not to count out LeBron James. Well, I've covered five LeBron Finals, and I'm here to tell you: he knew. He spoke about Golden State with a tone of "What can I do? They won 73 games, I beat them, they added Kevin Durant." The Cavaliers managed to make things close with a chance to win in Game 3 before Kevin Durant's cold-blooded, series-ending dagger. In the end, the Cavaliers got their requisite single face-saving game, but the end result was ... anticlimactic.

And while you are at it, don't forget to celebrate the imperfections. While on a 10-day trek in the Himalayas, I learned that imperfections are beautiful too. The rough edges of the mountains, the heavy hail storms in the middle of the afternoon, were "inconvenient" but added to the beauty of the trek. I am acutely aware now that in my pursuit of perfection at work, I have often failed to recognize that imperfections are also a core part of our identity that needs to be preserved and not always changed.
