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

直到最近,Weill Cornell Medical College的科学家们至少在老鼠和猴子身上实现了这一点。这种人造视网膜,它的芯片可以将画面转换为电子信号,而它的微型投影机可以将电子信号转化为投影光线。
"The Chinese government, universities and investors have provided a friendly environment for young startups. However, the failure rate of fresh graduates founding startups is still too high due to the lack of experience, resources and networking," said Wang Yixin, a senior consultant at Zhaopin.

从该剧2007年首播至今,我们似乎患上了哈德利·弗里曼(Hadley Freeman)在《卫报》(The Guardian)上所称的“广告狂人狂热症”(madmenalaria)。
听起来像是泰勒斯威夫特,但事实上,却是她一直以来的竞争对手,凯迪派瑞。这主要归因为她的棱镜世界巡回演唱会。现在演唱会的热潮已归于平静,派瑞今年凭此吸入13.5千万美金。在我们评分期间的126场演出中,她平均每个城市赚得2百万美金,再加上与科蒂,克莱尔和封面女郎的合约,得到了她的总共收入。
但最近,回购势头开始减弱。跟踪回购比例最大的100家公司的标准普尔500回购指数最近创下了自2012年年中以来的首次下跌。随着股价连创新高,股票回购所产生的推动作用消失,公司投资较长期项目或使用多余现金进行收购变得更有价值。

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.

But that hasn't stopped scientists from growing actual human brains in a lab. Starting with nothing but stem cells, scientists in Austria this year managed to create brains equivalent to those in nine-week-old fetuses. These miniature brains are the size of peas and are incapable of thought—so far. The one thing keeping the brains from growing beyond this stage and becoming fully functional is that they have no blood supply.
