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

“有个人给同事发了条短信说自己辞职了,并请她把这条短信转发给高管。”

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.

On Aug 21, the country came to a pause as millions of Americans — even the president — put on eclipse glasses and stopped to take in the first eclipse to cross the United States since 1918. Its path across the United States was a scientific bonanza for astronomers who were able to more easily point advanced equipment at the sun.
No one in Detroit has forgotten the snowstorm of 1999, when airplanes were mired for hours on the tarmac at Detroit Metropolitan International Airport. Likewise, US Airways encountered its own holiday mishap in 2004-05, when more than 72, 000 bags were lost or damaged.
During the same period, Braziland Russia slashed their holdings to USD 261.7 billion and USD 108.9 billion,respectively.
Taken together, these events and strategic initiatives highlight the Chinese aerospace industry’s realization that, in order to become a globally competitive player, it will need depth as much as breadth. After getting their hands on both ends of the value chain—aircraft design and final assembly—the Chinese now understand that what will make or break their industry over the long term is what happens in the middle of the value chain, at the component and subsystem levels. And that is why China’s ambition to compete with Boeing and Airbus, as well as with GE and Rolls-Royce for aircraft engines, is now more credible than ever.

当然,影片中最惊人的一幕是外星人遇到一个涉世不深,外表因为多发性神经纤维瘤而丑陋的年轻男子,由亚当·皮尔森扮演。格雷泽带来的这一幕是全然无畏而且毫无感情波动的,或许这是从大卫·林奇的《象人》这部影片的主题变化而来。外星人并不会在本质上区分这位年轻男子的长相,但是她与这位男子相遇——两个外星人的遭遇?——触发了危机,使得她成为了猎物,而不是猎人。
In Belgium's case, the reasons are more readily apparent. A nation sewn largely from a patchwork of three peoples, the Flemish, Walloons, and Germans, its football team nevertheless features several stars of African descent. Currently, Belgians of Moroccan descent -- including midfielder Marouane Fellaini and winger Nacer Chadli -- make up the biggest non-European group; for many Moroccans, French is a second language. Like France with its North African and Caribbean contingents and Germany with its Turks, Belgium's national team has benefited from multiple populations: one from Western Europe, one from Africa, and one from Eastern Europe.

About 40 per cent of entrepreneurs derive most of their income from their company with an average salary of about $194,000 compared to $171,000 for non-entrepreneurs.

在出售给Facebook前,WhatsApp一直特别反对植入广告。该公司首席执行官让o库姆在自己桌上一直贴着联合创始人布莱恩o阿克顿留下的一张便条,随时提醒自己牢记公司的核心价值观:“不要广告!不要游戏!不要宣传噱头!”这样一来,短信应用只好想出别的创意。比如Tango就在用户的短信“收件箱”里插入广告。中国互联网巨头腾讯公司旗下的短信应用——微信,则通过游戏、贴纸(类似于表情符号)和移动购物等方式谋取赚钱之道。Kik则提供一种被一些人称为“聊天广告”的功能,用户通过它能和幽默网站Funny or Die及电影信息网站Moviefone这类品牌运营的聊天程序进行交谈。

'Her,' which was written and directed by Spike Jonze, takes romance into the virtual realm, and its hero on a gently crazed journey of genuine passion. Joaquin Phoenix is the poignantly lonely guy who falls in love with his smartphone's new operating system.

Estimates vary, but the research firm IDC projects that wearable tech will exceed 19 million units this year—more than triple last year’s sales—and will soar to 111.9 million units by 2018.

But before that happens, the nascent market has that pesky wouldn’t-be-caught-dead-wearing-it hurdle to clear.
