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

Here are the top 5 share repurchases authorized so far this year, according to data collected by Birinyi.

里奥斯工作非常努力。她很小的时候就从萨尔瓦多来到了美国。以优异成绩从高中毕业后,她一边养家,一边读完大学。成立Nation Waste Inc.公司的时候,她并没有感到害怕。22岁的时候,里奥斯刚刚从休斯敦大学(the University of Houston)毕业几个月就贷款购买了两辆卡车,毅然投身由男性主导的垃圾处理行业。目前,这家位于休斯敦的公司有24名全职员工。里奥斯说:“回头看看过去的经历,总是让我感到吃惊。我很小的时候就跟着父母来到美国,现在我正在实现我的美国梦。”

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.

简言之,无叶风扇就是没有叶片的风扇。它的工作原理是先将空气吸入风扇基座内部,然后通过扇头环形上的洞将空气吹出。这款风扇据说是詹姆斯·戴森发明的,并命名为"气流倍增器"。就像可以飞行的喷气背包一样,无叶风扇被《时代周刊》评为"2009年度伟大发明"之一,同样它也不是世界上第一个无叶风扇。实际上,第一个无叶风扇于1981年被日本的东京芝区电力公司获得专利。尽管东京芝区电力公司的无叶风扇并没有用于生产制造,但詹姆斯的无叶风扇的原始设计与其设计相似,所以专利局拒绝授予詹姆斯这个专利。尽管授予东京芝区电力公司的专利已经过期,但在授予詹姆斯这项新专利之前,专利局需要他提供该设计的创新之处。詹姆斯的经理吉尔·斯密斯并没有否认这两种无叶风扇间的相似性,只是说两者间的差异在于所用"科技"不同。

The Cassini spacecraft has been sending home images of Saturn, its rings and its moons since arriving at the gas giant in 2004. The mission ended in September with a planned fiery crash into Saturn’s atmosphere. While it studied the planet, Cassini explored moons — Titan and Enceladus — that could be home to extraterrestrial life. The probe also gave us great insight into our solar system, and will continue to do so for years as scientists pore over the data it collected.
