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

2012年,谷歌发明了谷歌眼镜,一台你能戴在你脸上的电脑。在街上行走或者进行每天的任务的时候戴着它,可以同步看一些覆盖在眼镜上的日程会议,短信及地铁警戒等信息。戴着它行走的时候,可以用它们打视频电话,甚至把直播视频上传到网络,这一切都不需要动手。谷歌眼镜可能挺酷的,挺新颖,还有创新性,但是它绝对不是第一副可佩戴的电脑眼镜。

'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.

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.

Actuaries put a financial value on risk for instance, the chances of a hurricane destroying a beachfront home or the long-term liabilities of a pension system. In a world awash with risks of the natural and manmade variety, the profession is booming, says Tony Lee, publisher of CareerCast.com. In addition, he says, 'there's a severe shortage of actuaries, ' so wages are rising. (The median salary for actuaries in 2010 was $87, 650, according to the Labor Department.)

会。目前有很多利好因素:利润、经济增长和美国减税。但这些都是已知因素。按照历史标准看,眼下股价高得离谱,但这对短期走势毫无参考价值。最终还是要看流动性,自从股市在2009年从危机中走出来以后,流动性始终驱动着股市上涨。如果一切按计划进行,到2018年底,各国央行会在缩表和撤除流动性。如果各央行果真这样做,标普500指数很可能会牛气不再。但只要稍有风吹草动,央行官员们就会迟疑。这股牛气应该会继续。

For now, most of the activity around bitcoin is monetary in nature, so it makes sense that its critics point to volatility. Though the value of one bitcoin in U.S. dollars has fallen 67% in the past year, its value over the past two years is up 1,879%, according to the market price chart at blockchain.info. So whether it’s a good investment or a bad one is a matter of perspective.
