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

With China now not only “fully integrated”, but perhaps starting to retreat from this position as it brings more of its supply chain onshore, unless Africa can succeed in following China’s path, he adds: “I think we are going back now to a situation where we don’t think there is any particular reason for trade to grow faster than GDP.”

还有呢,就是道德。“如果你通过使用公司的设备来设法离开这里就实在对你的雇主太不公平了。”福斯说。

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.

But the best answer to the Oscar statue display question comes from Timothy Hutton, the youngest person ever to win the Academy Award for best supporting actor. Hutton, who won the gold figurine for his role in Ordinary People, was apparently having a party a number of years ago. His sister popped the Oscar in the fridge alongside the beers so that guests would happen upon it en route to refreshment. The statue is apparently still in there.
In 2011, at age 15, D'Aloisio closed a seed round of funding from Li Ka-shing. A year later, Summly launched, and within a month it had attracted 500,000 users and became the number-one news app in 28 countries. The Yahoo! sale capped off a remarkable run for someone not yet out of high school. But it's not mere technological savvy that sets D'Aloisio apart. Since long before he could shave, he has been driven by an intense curiosity and a desire to make some sort of mark on the tech world. Not just to create but to build and, yes, to monetize.
Still, the optimistic view is that several roadblocks to recovery -- an over-indebted consumer, a moribund housing market and shellshocked banks -- are no longer holding back hiring. Barring an unforeseen shock to the economy, this could mean 2013 will be another year of slow but steady growth.[qh]

Analysts believe the launch will help Apple to overcome its growth problem of the last two years. In markets such as America and Europe, where smartphone ownership is close to saturation and many customers are holding on to their existing handsets for longer, the best way to drive faster revenue growth is by charging more for each device, rather than simply relying on unit growth.

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 biggest story of the festival had nothing to do with films. It was about shoes. On Tuesday trade magazine Screen reported that a group of women had been denied access to a screening of Todd Haynes' Carol because their footwear – flat shoes with rhinestones – was unsuitable for the red carpet. Further tales came tumbling forth, social media erupted in indignation and soon enough we were soon dealing with a fully fledgedscandale. The Cannes press office rushed out a garbled statement: “Rules have not changed throughout the years (Tuxedo, formal dress for Gala screenings) and there is no specific mention about the height of the women's heels as well as for men's. Thus, in order to make sure that this rule is respected, the festival's hosts and hostesses were reminded of it.” Well, that cleared that up. Perhaps wisely, press screenings are exempt from any dress code: scruffy journalists are free to ascend the Palais' steps in flip flops and trainers.

上世纪70年代,考林斯出生在落后的、种族隔离时期的南非。她的童年经历让她更关注通过民间的努力改善贫困女性的生活。创办Wonderbag的灵感源自她观察祖母借助垫子做饭的经历。Wonderbag使用保暖技术在8至12个小时内烹饪食物,无需额外增加燃料。考林斯亲眼见证了非洲女性使用Wonderbag所带来的好处——它减少了她们收集柴火的时间。每卖出一个Wonderbag,这家公司就会向非洲的家庭捐赠一个这样的袋子。过去四年,Wonderbag已经走进600,000个非洲家庭。考林斯还通过亚马逊(Amazon)在美国推出了Wonderbag,并希望到2014年的时候能够通过其他零售商出售自己的产品。

Yes — just. Democrats will regain control of the House of Representatives in the November midterm elections. Though they will not take charge until January 2019, they will waste no time preparing the House Judiciary paperwork. Mr Trump will label it a “witch hunt”. But another year of his surreal presidency makes it all but inevitable Democrats will campaign on a pledge to hold him to account. Whatever Robert Mueller’s investigation unearths before then is unlikely to turn enough Republicans against him.

Taken together, these events and strategic initiatives highlight the Chinese aerospace industry’s realization that, in order to become a globally competitive player, it will need depth as much as breadth. After getting their hands on both ends of the value chain—aircraft design and final assembly—the Chinese now understand that what will make or break their industry over the long term is what happens in the middle of the value chain, at the component and subsystem levels. And that is why China’s ambition to compete with Boeing and Airbus, as well as with GE and Rolls-Royce for aircraft engines, is now more credible than ever.
