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

为保证更快的经济增长就必须要要消除美联储所担忧的另一个恶魔:通货紧缩,或者说价格下降。Baumohl 称“经济增长达到3%以上,并且自90年代以来新增了大量工作的国家发生通货紧缩几乎是不可能的”。

他说:“国内需求增长太慢,而新增出口订单的增幅又放缓至5个月内的低点……我们依然预计(中国政府)会推出进一步货币和财政宽松举措,以抵消经济增长的下行风险。”
"It may affect them for life," Dershowitz said.

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.

Scott Brooks gets leeway as he learns his roster, and injuries continue to play too big a role. But I just can't fathom why this team is so much worse than the playoff team from a couple years back. The other piece is that it's unlikely the Wizards can conceivably be bad enough to get a top-five pick.
Mr Williams’ medium to long-term view is arguably more gloomy than that of Mr Baweja. He believes the 25-30 year period during which growth in global exports far exceeded that of global GDP, represented a “surge of globalisation that has come to an end”. In other words, the current slowdown in trade growth is structural, not cyclical.

There has also always been a certain fluidity to this concept of whiteness. Irish and Italian immigrants to the United States, and Jews in Britain, were once seen as separate from the white national majority, and are now generally considered part of it, benefiting from racial privilege. At the same time, Jews’ white skin did not protect them from being cast as outsiders by some of Mr. Trump’s supporters who have circulated anti-Semitic memes on social media.

正如这届美国政府中一切与贸易有关的事项一样,韩美贸易协定(Korus)的未来也不可避免地引发了激烈辩论。本届政府内部强烈反对退出该协议的是特朗普安全团队,他们认为在一场地缘政治危机期间切断与重要盟友的贸易纽带很可能不是个好主意。美国企业也不支持退出。这两股力量都可能意味着美国政府至少在短期内不会发出任何威胁。但是话又说回来,首尔方面的政治局势也不稳定。韩国新政府是否可能行使自己退出协定的权利呢?

It was Somerset Maugham who said the French Riviera is “a sunny place for shady people” – and looking around at all the 'models' in the hotel lobbies and the men in dark sunglasses who seemed to know them, I knew what he meant. Behind the festival's shiny facade, there is an unseemly side – and beneath the azure waters, a polluted mess. The French diver and environmentalist Laurent Lombard's video of the Cannes seabed strewn with waste and debris went viral before the festival began. We were assured there was no danger to swimmers, and the mayor had it cleaned up according to the Daily Mail – but the Med had certainly lost some of its sparkle.

当年的荷兰金融市场固然没有今天的任何科技,但他们的很多做法都和今天的交易员一样。投资者们买入证券,有时会用买入的股票质押获得贷款。用今天的话说,他们基于保证金买入股票。贷款机构为了自身安全,会要求一个超出贷款金额一定百分比的“折幅”,质押现金或证券。如果证券价格下跌超过一定幅度,贷款机构会要求投资者交出更多资金,与“折幅”保持一致。如果投资者拿不出追加保证金,贷款机构有权将证券平仓,收回贷款额。

Helsinki-based developer Remedy Entertainment has blurred the line between Hollywood and games with previous incarnations Max Payne and Alan Wake. Now the studio is combining next-generation visuals with the tension and drama of scripted television. Set in the university town of Riverport, Quantum Break puts players in control of Jack Joyce and Beth Wilder, a pair of ordinary people who are given the extraordinary power to manipulate time after an accident that creates a time rift. Time will randomly break down during the game, which causes disasters in the environment that pause, stutter, rewind and freeze. Fans of Max Payne’s bullet time will see new strategies emerge with gunfights involving time-amplified combat as the player fights against the Monarch Corporation. In addition to the virtual storyline, the game features custom live action storytelling that’s personalized based on the decisions one makes.
