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.

More recently, however, General Motors made a self-driving car in 1958 that adjusted its steering wheel based on the alternating currents given off by a wire placed inside the road. While the vehicle did actually drive itself, it does not qualify as the first autonomous vehicle because it depended on wires placed inside the ground. The world's first autonomous vehicle was made by S. Tsugawa and several of his colleagues at Japan's Tsukuba Mechanical Engineering Laboratory. However, German engineer Ernst Dickinson is regarded as the pioneer of the autonomous car. In 1987, he developed the VaMoRs which was capable of traveling more than 90 kilometers per hour (55 mph) for about 20 kilometers (12 mi). Seven years later, he made the VaMP, which could recognize road signs, know its own position in a lane, detect other vehicles, and even decide when to change lanes. And a year after that, he and his team made another autonomous vehicle which traveled from Germany to Denmark. The vehicle had a maximum speed of 180 kilometers per hour (111 mph) and was controlled by a human for about 5 percent of the journey.

2. 美国页岩油。截至2014年底,美国页岩油日产量已经超过900万桶,比2007年增加了80%。这些页岩油是造成石油供给过剩的主要力量,而供过于求是2014年油价暴跌的诱因之一。总的来说,美国页岩油开采公司都搬起石头砸了自己的脚,但关键在于,西德州轻质低硫原油(WTI)价格跌破60美元对它们有何影响?页岩油钻机数量不断减少,相关开支也遭到削减,然而到目前为止,美国页岩油产量依然稳定。按照当前油价,这个行业能否维持产出水平,或者说美国页岩油产量会不会减少将对国际市场供应乃至油价产生重大影响。

BETTER CALL SAUL (AMC, Feb. 8) Vince Gilligan and Peter Gould’s “Breaking Bad” spinoff is probably the most anticipated new series of the winter.
