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

Now, Curry and the Golden State Warriors are right road of adding another accomplishment.

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.

会。目前有很多利好因素:利润、经济增长和美国减税。但这些都是已知因素。按照历史标准看,眼下股价高得离谱,但这对短期走势毫无参考价值。最终还是要看流动性,自从股市在2009年从危机中走出来以后,流动性始终驱动着股市上涨。如果一切按计划进行,到2018年底,各国央行会在缩表和撤除流动性。如果各央行果真这样做,标普500指数很可能会牛气不再。但只要稍有风吹草动,央行官员们就会迟疑。这股牛气应该会继续。

In my adolescent years on the foothills of Himalayas, I had a friend we all referred to as the "dreamy guy." He would spend his days enjoying the smallest of things – color-tagging butterflies, counting peaks on the horizon, making stories out of cloud formations. He was a happy soul, deeply receptive to life's beauties and easily excited. I knew this guy many years ago and I thought about him today as I sat down to write this piece for you, dear class of 2013.
