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

苹果公司和中国移动之间的协议尘埃落定之后,有关苹果下一款重大产品发布的供应链传言又开始浮现。Digitimes报道称,据“上游供应链的消息”,苹果公司正酝酿在明年5月发布一款5英寸屏幕的iPhone 6“平板手机”,在明年10月发布一款大尺寸平板电脑。

Such insights are of particular interest to litigation funders, who back claimants in return for a cut of damages and who try to assess the likely outcomes of disputes before committing their money. But that may have to be 2019’s breakthrough, or probably beyond.
But that moment, try as Google might, has yet to come. Some reports have named 2014 as the year when wearable devices will hit the mainstream, but a newer study from L2, a digital research firm, confirms what many have been quietly fighting for: wearables are still not socially acceptable, creating a significant hurdle to further sales.
目前已经被泄露的照片多达10个G。据《北京日报》12月1日报道,著名在线P2P借贷平台"借贷宝"也和此次事件有关。

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.

Yes. Mr Meade is the candidate of the ruling Institutional Revolutionary Party, or PRI. His main rival is the hard leftist Andrés Manuel López Obrador, a passionate orator who can work a crowd. Mr Meade has a lot to overcome: he will have to convince voters that they can trust him, after he put up petrol prices by 20 per cent overnight in January, triggering a surge in inflation. He will also have to reveal himself as his own man, not just a clone of an unpopular government that has failed spectacularly to rein in rampant corruption and crime. But backed by the formidable PRI get-out-the-vote machine, he could prove unstoppable. In Mexico’s one-round-only system, 30 per cent of the vote might be enough.

D'ALOISIO HAS BEEN quoted opining that 'time is the new currency.' It's the driving notion behind Summly. It's also a strangely wise observation from a 17-year-old. At that age, many of us had more time on our hands than we knew how to fill without plummeting into severe boredom. It's easy to forget-conversing over lunch in a London caf钼 or strolling through the Tate Modern-that D'Aloisio was born in 1995 and has not yet graduated from high school. Or that he still lives in his childhood bedroom, in a cozy upper-middle-class home. As I chat with his parents, he excuses himself to work on his computer. Slouching down the hall in his stocking feet, hems of his skinny jeans brushing the hallway carpet, it is the most kidlike you will ever see him.

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.

My grandmother’s favorite poem was Invictus by William Ernest Henley.

Recognize opportunities when they arise and get comfortable saying “Yes.”

In reality, Britons are just as likely to jump to the front of a queue and then punch the person behind them for coughing. It all depends on how muggy it is.
