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

Anyway, it's nice to see that LeBron has filled into his monster physique nicely in the past nine years.
At its Worldwide Developer Conference in June, Mr Cook was mobbed by app makers who asked him to pose for selfies. By October’s iPad launch, he was even cracking jokes at his own expense. Clad in his habitual but unglamorous uniform of black untucked shirt and jeans, he said that Apple Watch had been well received by “people who know a lot about fashion and style — even more than I do”, pointing a knowing finger at the chuckling audience.
William Leung, portfolio manager at Cohen & Steers, the US investment house with $4bn of assets exposed to Asia, agrees. He argues that speculative investment will be driven out of the market as prices fall. He adds that a trend in the industry towards alternative investments should mean that the price of real estate investment trusts rises even if the value of underlying assets grow more slowly. “We don’t think this correction will be so sharp,” he says.

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.

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.

Leatrice Eiseman, the executive director of the Pantone Color Institute, said the joining of the two colors reflected “a soothing sense of order and peace” — presumably an attractive thing to incorporate into a product at a time of insecurity and global turbulence.

其实,在第一部iPhone手机发布的前一年,LG集团已经推出了全触屏手机。虽然那也不是第一台触屏手机。1992年,世界上第一台触屏手机IBM Simon发布。而触屏技术在"西蒙"之前已经出现。1965年,E·A·约翰逊发明了第一个触屏设备——平板电脑,截止到1995年,一直由空中交通管制员使用。本特·斯顿普和弗兰克·贝克(Frank Beck)在20世纪70年代早期发明了电容式触屏,与约翰逊所发明触屏不同的是,它不能用手指操作,而是需要使用触控笔。在1971年,山姆·赫斯特发明了第一台电阻式触屏,他称之为"电子图表"。手指和触控笔都可以对它进行操作。在1985年,惠普公司发明了世界上第一台触屏电脑H-P150。在1993年,苹果公司也发布了第一个触屏设备——牛顿个人电子助理设备。但此产品并不成功,它的销量很低。

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.

The one thing keeping the brains from growing beyond this stage and becoming fully functional is that they have no blood supply.
