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

两周后,伯恩海默等几十位著名的早期绘画大师作品交易商出席伦敦的夜间拍卖会。过去,他们通常会在这些拍卖会上购买一些作品,以备在第二年3月的荷兰马斯特里赫特欧洲美术博览会(Maastricht European Fine Art Fair)上展示。但是由于卖家们鼓励苏富比和佳士得报出更高的估价来争夺自己的拍品,所以拍卖行只针对少数富豪进行宣传,现场竞价十分冷清。

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.

Until now Thor has been the neglected child of the Marvel Cinematic Universe. Though some liked Kenneth Branagh’s first film featuring the god of thunder, Chris Hemsworth was arguably overshadowed by Tom Hiddleston’s preening popinjay of a villain, Loki. And the second film, the humourless Thor: The Dark World, is widely regarded as the worst film released by Marvel Studios to date. So to inject new life into this sagging franchise, Marvel brought in New Zealand comedy auteur Taiki Waititi to add some Kiwi quirk. This time Thor faces down the goddess of death, played by Cate Blanchett. Thor may have the hammer, but she has the attitude. Released November 1 in Serbia and Hungary, November 2 in Cambodia and Israel and November 3 in India and Canada. (Credit: Marvel Studios)
The Warriors are one of the best teams in NBA history, and you can put their championship run up against any team in NBA history for the best playoff performance ever. But there's also a legitimate question of what this means for the sport. If the best or second-best player of all time stands no chance against this team, what does it mean for the sport's competitiveness? It hasn't been a problem so far, thanks to an extremely wild offseason, but the question remains: what happens to a competitive sports league when it's not truly competitive at the highest level?
So far this year, companies have announced 376 share-repurchase initiatives for a total of $261 billion, according to data from Birinyi Associates. That's nearly 72% higher than 2012, though slightly lower when compared to the same period in 2013, which was a record year for buybacks.

If audiences didn’t yet know the film was set in the early 1980s, one look at Anna’s straight bangs confirms it. The rest of her shoulder-length hair forms a slight curved frame around her face. It’s a simple look, but a powerful one for this woman, whose husband, Abel (Oscar Isaac), runs a heating oil business, but whose past is a little more complicated.

iPhone推出一款更大屏幕iPhone手机的迫切性部分来自于亚洲市场——三星平板手机声势浩大地占领了这个市场。假设苹果和中国移动签订的协议包括上述即将推出的新品,那么新款iPhone推出时通常会出现的价格调整将使iPhone 5C对中国市场而言更为便宜且更具吸引力。而这对5C来说也是正确的方向——目前为止,苹果公司对该款产品的销售额颇为失望。或许关于5C重要的一点是,它不是5S,所以将来它可以在不对苹果旗舰产品价格造成压力的情况下进行打折。
例如,美国和亚洲向投资者推介产品的方式存在明显区别。在亚洲,很大比例的基金(一些人估计为90%)是以佣金为基础。这对ETF不利,因为它们在股票交易所公开交易,在结构上不便向可能推荐它们的银行、券商或理财顾问支付佣金,这与该地区的共同基金行业不同。
