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

温斯顿?丘吉尔(加里?奥德曼饰)刚刚上任英国首相,就面临着一个他生命中最关键的抉择:暗流涌动,是与纳粹德国和谈,还是依旧保持坚定立场,为了国家的理想、自由而战斗。
In that meeting, he told Jacobs that such problems would decrease, as China is reforming its management system in science and technology, according to a statement by the association on Friday.

The value created by the service sector rose to 51.6 percent of GDP.

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.

In addition to WeChat's core private and group messaging functions, users can also find new contacts by using the application's Drift Bottle function, where a user records a message and sends it out to see in a virtual bottle for a stranger to pick up and respond. Its Look Around function, similar to some mobile dating applications, allows users to browse the profiles of other users who are in close proximity. It also has a function called Moments that allows users to share photo albums publicly with groups of contacts, much like photo-sharing application Instagram.
If any movie can bridge the deep racial, generational and class divides in American life — at least for a couple of hours — it would have to be this revival of the ancient “Rocky” franchise. Sylvester Stallone, shuffling into the wise old trainer role, gives perhaps the loosest, warmest performance of his career. Michael B. Jordan, as Adonis Johnson, Rocky’s protégé (and the illegitimate son of his onetime rival and long-lost friend, Apollo Creed), continues his emergence as one of the vital movie stars of our moment. As for Mr. Coogler, with his second feature as a director he proves himself to be a true contender. (Read the review)
So the messaging apps have gotten creative. Tango, for example, inserts ads within a user’s messaging “inbox.” WeChat, a popular Chinese app that is owned by Tencent, makes money through games, stickers (which are similar to emojis), and mobile commerce. Kik offers a feature that some are calling “chatvertising,” where users hold conversations with chat-bots powered by brands like Funny or Die and Moviefone.

2. American shale.By the end of 2014, the U.S. was producing more than 9 million barrels of oil per day, an 80 percent increase from 2007. That output went a long way to creating a glut of oil, which helped send oil prices to the dumps in 2014. Having collectively shot themselves in the foot, the big question is how affected U.S. drillers will be by sub-$60 WTI. Rig counts continue to fall, spending is being slashed, but output has so far been stable. Whether the industry can maintain output given today’s prices or production begins to fall will have an enormous impact on international supplies, and as a result, prices.

No. This is possible, of course, but with luck, Mrs May has at least now ensured that the UK is not going to tumble over a “no deal” cliff in 2019. In December 2017, Consensus Forecasts’ prediction for the UK was of 1.5 per cent growth in 2018. Its forecasts for Japan and Italy were even lower, at 1.3 per cent. So the chances that the UK will have the slowest-growing economy in the G7 next year should be around one in four.

Yes, even if real GDP growth does not. Speculation over the true GDP growth rate in China, as opposed to the official one, has spawned a cottage industry of specialist economists. The official figures are deceptively stable and serene thanks to suspected “smoothing” by the Chinese authorities, as they bend the figures to fit growth targets. So even if growth does stumble in 2018, the official growth rate is almost certain to come in above the preordained 6.5 per cent.
