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

1. "Game of Thrones" (5.9 million)

The reading is just below economists' forecasts but it's not altogether surprising. When the People's Bank of China unexpectedly cut interest rates last month, some analysts said the move was likely a pre-emptive one and that a spate of weak data was likely ahead. Well, here it is.
Bolder lawyers will start working with more “sci-fi” programs that claim to predict the outcomes of legal disputes before they have reached court, by analysing similar cases and past rulings, opposition tactics and win/lose statistics, the success rates of certain lawyers before certain judges, and so on.

By 2020, annual box office sales are expected to reach 100 billion yuan, according to industry estimates.

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.

学者们对比特币的兴趣似乎也是前所未有的高涨。有190本关于比特币的白皮书在2014年发表,就在2013年,还只有55本。业余和专业作者们也纷纷为比特币著书立传:亚马逊列出了437本2014年出版的关于或涉及“比特币”的书籍,相比之下,2013年该数字为143本。【这是基于主题搜索的结果,因而其中包括《Bitcoin Bimbo 3:卧底警察科幻色情作品》(Bitcoin Bimbo 3: Undercover Cop Science Fiction Erotica)这种不大相干的结果】今年,体育迷们应该都注意到了首届比特币圣彼得堡碗比赛,这是北卡罗莱纳州立大学与中佛罗里达大学间的高校橄榄球季后赛。ESPN电视台迅速将BitPay以比特币形式支付的50万美元特许权费兑成了美元。
In 2010, the Martin Aircraft Company introduced a jetpack it called "the world's first piratical jetpack." The jetpack even won a spot in Time's Top 50 Inventions of 2010. While its development has been on since 1981, the world's first jetpack is known to have flown in 1958. It was designed by Wendell Moore, a researcher at Bells Aerosystems. Early prototypes of Wendell's jetpack could reach a height of 5 meters (16 ft) and remain airborne for three minutes. This attracted the attention of the US Army, which funded the project with $150,000. Several test flights were later done for the US Army and even for JFK himself. The army later stopped paying for more research into the project because the flight time and distance were not convincing enough. NASA also wanted to use the jetpack for their Apollo 11 mission to serve as backups in case their lunar module malfunctioned. They later changed their minds, going for the lunar rover instead. After this setback, Bell discontinued further research on the jetpack.

Taken together, these stories reveal “a new global food order, and a new health crisis.”

4. 欧佩克的下一步行动。说到去年的油价暴跌,石油输出国组织(OPEC)起了很大作用(或者说要承担很大责任)。虽然许多评论人士都说欧佩克保持原油产量不变无关紧要,然而,仅油价在该组织11月份会议过后出现暴跌这一事实便充分证明了该组织对油价走势的影响力。目前,欧佩克——更确切地说是沙特——仍在坚持己见,毫无下调生产配额的迹象。2015年这一情况是否会得以延续,仍有待观察。

So with such a strong South American contingent, where will the main challenge come from ? Well, the big guns from Europe is the obvious answer. And where else could you look for a team of Champions than Spain. Having won the last World Cup, sandwiched between two European Championship triumphs, this is a team that not only knows how to play fantastic football, but that knows how to win. So whilst Messi and Ronaldo get all the annual plaudits and player of the year titles, the likes of Xavi and Iniesta go about winning all the major trophies. So will they be as string this year ? Well, worryingly for the rest of the world, yes. Not only are most of the old guard still there but talented youngsters such as Koke and Thiago Alcantara have joined the ranks. Not only that, but they've managed to grab a prolific striker, Diego Costa, from under the noses of the host nation, with the Atletico Madrid forward opting to play for Spain, rather than the nation of his birth.
