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

On Aug 21, the country came to a pause as millions of Americans — even the president — put on eclipse glasses and stopped to take in the first eclipse to cross the United States since 1918. Its path across the United States was a scientific bonanza for astronomers who were able to more easily point advanced equipment at the sun.

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.

In contrast to last year when the vast majority of economists expected the ECB to launch full-scale quantitative easing, just under half of the 33 respondents thought the ECB would do nothing this year. The rest said the ECB would expand QE or cut interest rates, although some of those who expected more easing stressed that the central bank was unlikely to radically reshape its existing policy response.

例如,佳士得给威尼斯艺术家弗朗西斯科·丰泰巴索(Francesco Fontebasso)在18世纪中叶创作的油画《井边的丽贝卡和埃利泽》(Rebecca and Eliezer at the Well)的最低估价为12万英镑。根据Artnet的数据,在1990年的拍卖会上,这幅令人愉快的洛可可装饰风格的油画是以28.6万英镑购得的。在12月8日的拍卖会上,它仅得到一个电话出价——11.5万英镑(不含佣金),约合17万美元。而投资者们可不认为在购买沃霍尔(Warhol)或巴斯奎特(Basquiat)的作品25年之后会损失约40%。如果一幅早期绘画大师的作品被搁置在交易商的画廊里,想转卖它就更加困难。
