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

报告还写道“这一增长进一步依靠视频编辑技术,在第三季度显著增长了19%,因为视频内容已经成为了大多数顾客为中心的网站的首要的吸引和号召行为。通过社交媒体的大量的视频营销也助涨了这一需求。”
But because I can’t help but hope that with the end of “Mad Men” comes the end of a period in fashion that has seen designers become trapped in the past to an almost stifling degree. At least the past as it looked in the 1960s (which in the beginning, let us not forget, looked a lot like the late 1950s) and early ’70s.

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.

这部亚当·桑德勒和德鲁·巴里摩尔主演的轻松浪漫喜剧,似乎最不能反映现实生活,但实际上它确实部分基于真实故事。桑德勒扮演的兽医爱上了巴里摩尔,而她的记忆每天都会重置。他了解到,车祸造成创伤性脑损伤后,她就一直在重播同一天。因为她一直生活在谎言中,桑德勒的角色很苦恼,并制作了一系列录像,解释她的车祸和生活,给她每天早上看。

当年的荷兰金融市场固然没有今天的任何科技,但他们的很多做法都和今天的交易员一样。投资者们买入证券,有时会用买入的股票质押获得贷款。用今天的话说,他们基于保证金买入股票。贷款机构为了自身安全,会要求一个超出贷款金额一定百分比的“折幅”,质押现金或证券。如果证券价格下跌超过一定幅度,贷款机构会要求投资者交出更多资金,与“折幅”保持一致。如果投资者拿不出追加保证金,贷款机构有权将证券平仓,收回贷款额。

你可能觉得我们对于列清单的爱好是从“十诫”继承而来,但安伯托·艾柯( Umberto Eco)的说法却正相反,“清单是文化的起源”,他写过一本书,《无限的清单》(The Infinity of Lists),书中在讨论自己熟悉的东西时这样说道。而且,文化希望“让无限变得可以理解”,并且“创造秩序——不是永远如此,但通常都是这样”,所以才有了荷马在《伊利亚特》中的人名清单,以及你冰箱上贴着的,永远做不完的家务清单。“我们喜欢清单,因为我们不想死,”艾柯还说,这可能是对“清单体”(listicle)的最佳解释了。

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.
