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

这些项目一般是为平均年龄22岁的学员设计的。

The unemployment rate probably won't fall quite as rapidly in 2015, according to economists, especially if more people enter the labor force because jobs are easier to find. Yet another large spate of hiring similar to the gain in 2014 would make the low unemployment rate more believable.
今年年初,所有华尔街经济学家都呼吁提高利率,彭博社就这个问题调查了67位经济学家的意见,他们全票赞同,有鉴于此,任何一个有理性的人都不会想要增持对利率敏感的公用事业股。把赌注押在金融股上的投资者,回报进展缓慢;而瞅准了“低价”能源股的投资者,投资组合业绩在第一和第二季度曾因此推高,却在第三和第四季度被大拖后腿,可谓“成也萧何,败也萧何”。
林怡仲预测道,下半年A股IPO的数量或将维持与上半年相当,预计2016年全年A股IPO为120宗左右,融资规模在600-800亿元人民币左右。

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.

Like any college kid, Evan Wray loved using the tiny pictograms known as emoji. But he hated that there was no emoji to express his Fighting Irish pride with fellow University of Notre Dame students. So, alongside co-founder Sean O’Brien, he built a modest business on that disconnect. TextPride, as it was called, licensed images from brands in the sports and entertainment world and sold them as sticker packs. Within a messaging app like Kik, users could buy a packet of stickers for Disney’s Frozen for $1.99, for example.

The world's first flying bicycle flew on November 9, 1961, when Derek Pigott of the University of Southampton flew in a bicycle with an airplane-like body. It was called the Southampton University Man Powered Aircraft (sumpac). Derek furiously pedaled the air-bike to get it off the ground. It then flew 1.8 meters (about 6 ft) above the ground over a distance of 64 meters (210 ft). While the flight was short and slow, it still does not change the fact that it was the first bicycle to fly and at the same time, the first human-powered flight.

Rafael Corrales, a partner at Charles River Ventures, believes that the growth in a wide range of fields—from academia to infrastructure to policy—is a sign that 2014 was the biggest year bitcoin has had yet, despite its volatility. “In the short-term, that’s an easy knock from people who don’t understand or believe it can be something,” he says. “It’s the easiest thing for them to go after. In that transition stage, you’re going to have extreme volatility, so looking at its value over one year is kind of silly.” As for occasional hacks, he adds, “There are going to be bumps in the short term, but they’ll be solved sooner than later. And these things are being addressed by a huge community of people. So you have to be really excited, despite small bumps.”
