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

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.

今年选股遇到困难,部分原因在于市场顶部高度集中。苹果、伯克希尔o哈撒韦、强生、微软和英特尔这五只股票占去了市场涨幅的20%。如果你未持有上述股票,几乎就没有机会分享这场增长盛宴,而正是这几家公司的增长推高了标普500指数。市场上大部分股票的表现要逊色得多。研究公司路佛集团称,标普1500综合指数成分股中,仅有30%的个股跑赢了该指数。上次出现这样的景象,那还是1999年的事。

Dan Weiss “Fourteen” (Pi Recordings) There’s so much in “Fourteen,” the album-length composition by the drummer Dan Weiss: meticulous chamber maneuvers; avant-garde yowling; wordless vocals of new-music and northern Indian pedigree.

'12 Years A Slave' is shattering and anguishing, a singular anomaly in an entertainment medium. More than that, Steve McQueen's hugely ambitious chronicle of slavery in America is revelatory, a work of art that has been embraced by mainstream audiences. That's a testimony to the power of art (as expressed in John Ridley's script and performances by Chiwetel Ejiofor, Lupita Nyong'o and Michael Fassbender, among others), and heartening evidence of moviegoers' hunger for substance and meaning in the films they choose to see.

In one example, Christie’s was offering the mid-18th-century canvas “Rebecca and Eliezer at the Well” by the Venetian artist Francesco Fontebasso at a low estimate of 120,000. The pleasant piece of rococo decoration had been bought at auction in 1990 for $286,000, according to Artnet. At the Dec. 8 sale it fell to a single telephone bid of 115,000, about $170,000, before fees. Investors do not expect to incur a loss of about 40 percent a quarter century after buying a Warhol or a Basquiat. Reselling an old master can be even harder when that painting has been languishing in a dealer’s gallery.
