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

Committee Chairman Thorbjoern Jagland praised the work of the three recipients, saying that "we cannot achieve lasting peace in the world unless women obtain the same opportunities as men."
较为大胆的律师将开始采用更为“科幻”的程序,这些程序宣称在上法庭前就能预测法律纠纷的结果——通过分析类似案件和过往裁决、反对方策略和胜诉/败诉统计数据、某些律师在某些法官面前的成功率等等。

为了尝试遏制煤炭消耗量的增长,中国正在可再生能源和核能领域投入巨资,但尽管付出了这些努力,中国迄今为止依然是最大的温室气体排放国。中国每年因化石燃料燃烧和水泥生产排放100亿吨二氧化碳,几乎是美国的两倍,但美国的人均排放量依然远远高于中国。
Emerging market focused fund groups have endured a torrid year with sharply lower assets under management at Aberdeen and Ashmore. Emerging market exchange traded funds have also suffered heavy redemptions, with investors pulling $9.5bn from BlackRock’s iShares MSCI Emerging Markets and Vanguard’s FTSE Emerging Markets, according to ETF.com.

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.

The Cassini spacecraft has been sending home images of Saturn, its rings and its moons since arriving at the gas giant in 2004. The mission ended in September with a planned fiery crash into Saturn’s atmosphere.

The probe also gave us great insight into our solar system, and will continue to do so for years as scientists pore over the data it collected.

3. 需求弹性。解决价格低迷的方法就是低价。这是老生常谈,而且适用于供需两个方面。超低的原油价格会刺激需求复苏吗?某些国家对石油市场控制较严,低油价可能不会延伸到零售领域。印尼等国已经取消成品油补贴,这有利于国家财政,但消费者得到的实惠将减少。不过,美国汽油价格已跌破每加仑2.40美元,与2014年中期相比,降幅超过了35%。而此番降价已带动汽油消费的攀升。2014年底,美国汽油日消费量创2007年以来新高。低价可以提升需求,而需求的增长则可带动油价反弹。

不会。华尔街策略师预测美国政府的10年期借贷成本将在未来一年攀升至3%以上,这话就像尴尬的办公室聚会一样是圣诞节那段时间的固定节目。鉴于美联储退出量化宽松和美国减税,今年的预测看起来更有可能实现。然而,压低通胀和长期债券收益率的长期重大因素依然存在,并且仍然被低估。2018年美联储将至少加息三次,但10年期收益率不会突破3%。
