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

Influenced by the current economic situation, and resource relocation in China's financial market, the banking industry is away from the high-speed growth period, the expert added.

研究人员表示,去年之所以特别引人瞩目,是因为除了1月和4月以外,每个月都会创下新的全球高温记录,或与记录持平。

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.

But that hasn't stopped scientists from growing actual human brains in a lab. Starting with nothing but stem cells, scientists in Austria this year managed to create brains equivalent to those in nine-week-old fetuses. These miniature brains are the size of peas and are incapable of thought—so far. The one thing keeping the brains from growing beyond this stage and becoming fully functional is that they have no blood supply.

不会。这笔被誉为史上最大规模的首次公开发行(IPO),是沙特实际领导人穆罕默德本萨勒曼(Mohammed bin Salman)宏大经济重组计划的基石,因此沙特阿美IPO肯定会成行。该公司的股票将在沙特本国的证交所上市。不过,此次IPO计划在国外的部分不太可能是一次公开发行。唐纳德特朗普正在为纽约游说,伦敦也在全力以赴争取。香港和东京也在沙特的考虑之中。但沙特会转而选择非公开售股,或者在晚于预期的时间在国外上市。

James Gorman, a Times reporter, accompanied scientists who are trying to understand the genes that distinguish dogs from wolves. Humans who raise wolf puppies must spend 24 hours a day, seven days a week with them in order to socialize these puppies for scientific study. And while the pups may seem cute, they will grow to be predatory wolves, not humanity’s faithful companions. The researchers hope their work will help reveal the trigger that made some ancient wolves into the dogs we know today.
然后,事情峰回路转。库迪斯和沃斯发现,荷兰贷款机构对于Seppenwolde的倒闭做出的反应截然不同。那些曾经贷款给Seppenwolde、但一毛钱也没损失的贷款机构变得越发悲观,要求所有新借款人都提供更多的“折幅”。而那些从未贷款给Seppenwolde、因而躲过一劫的贷款机构则根本没有提高要求。事实上,这些贷款机构可能还略略降低了对借款人的“折幅”要求,至少表明他们和过去一样乐观。

On their first day of use, that first threshold was breached just after the return from the lunchbreak, prompting a 15-minute halt.
