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

The result doesn't look much like a nose—it's a bottle filled with liquid nutrient that cultivates bacteria. But give the “nose” a blood sample and let it sniff for a few days, and the bottle's dots will change color to indicate what bacteria, if any, it identifies.

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.

有些人仍坚持一种可称为“资源稀缺”的理论。该理论的核心是,资源开发遵循线性模式,低成本的资源最先被开发,也就是说,未来大部分乃至全部开发活动的成本一定会更高。遗憾的是,行业发展历史并不支持这一观点。过去几十年的经验表明,情况正相反。

What’s in a shade? If you are Pantone, the “color authority” and the dominant color trend forecaster, and you get to choose a “color of the year” every year, potentially a lot. It could include determining fashion’s direction (these are the hues that inform the fabrics that get bought by designers that get made into your clothes), influencing interiors, and even affecting how food appears. Still, I don’t think I’ve ever seen quite so much political and philosophical import attached to a color decision as I have for the 2016 “Color of the Year.”
The issue has also hit Beijing’s efforts to secure market economy status in the WTO, which it claims it will be entitled to automatically on December’s 15th anniversary of it joining. If China obtains that status it could affect the ability of the US and others to bring anti-dumping cases, as it would remove their ability to use prices in third countries for comparison.

Going, Going, Almost Gone Quentin Tarantino shot his latest, “The Hateful Eight,” in 70 millimeter, and the film is slated to play in almost 100 theaters that, like most of rooms across the country, now usually use digital projection. Whatever you think of Mr. Tarantino, try to catch “The Hateful Eight” on film so you can see for yourself how the industry-enforced switch to digital has radically changed movies.

Data from the Ministry of Industry and Information Technology showed the production of new-energy vehicles last month surged by 144 percent year-on-year to 16,100 units, and the output of fully electric passenger vehicles tripled from the same period last year, reaching 7,952 units in January. Official data showed that 97 percent of new-energy vehicles produced in January would be eligible for favorable taxation policies.

But although he foresees a “noticeable pick-up in exports” in the first quarter of 2017, the UBS man is keen to play down any euphoria. He believes year-on-year growth will weaken and maybe even turn negative by the second half of 2017 because “volume is not picking up in a big way and the base effect [of last year’s weak commodity prices] will fall off” during the course of 2017.

The immediacy for a larger-screen iPhone comes partially from the Asian market where Samsung’s phablets have made significant inroads. Assuming that Apple’s agreement with China Mobile includes these upcoming products, the pricing adjustments that normally occur with new iPhones could make the iPhone 5C significantly more affordable and attractive to the Chinese market. This would begin to make sense of the 5C, which so far seems to be a sales disappointment for Apple. Perhaps the important thing about the 5C is that it is not the 5S, so that down the road it can be discounted without putting price pressure on Apple’s flagship.

Thus it's rather a shock when you first encounter Nick D'Aloisio striding into London's Bar Boulud restaurant, firmly shaking hands and proceeding to outline his entrepreneurial vision. To imagine him in person, picture a Silicon Valley CEO blessed with an easy manner and 97th percentile media skills. Picture a guy who can confidently expound (while maintaining steady eye contact) on topics ranging from Noam Chomsky's theories to the science of neural networks to the immigrant mind-set to the Buddhist concept of jnana. And now picture this fellow trapped inside the gangly body of a British teen who might easily be mistaken for a member of the pop boy band One Direction-clad in a hipster T-shirt beneath a fitted blazer, hair swooping over his forehead, taking bites of a cheeseburger between bold pronouncements.

4. 欧佩克的下一步行动。说到去年的油价暴跌,石油输出国组织(OPEC)起了很大作用(或者说要承担很大责任)。虽然许多评论人士都说欧佩克保持原油产量不变无关紧要,然而,仅油价在该组织11月份会议过后出现暴跌这一事实便充分证明了该组织对油价走势的影响力。目前,欧佩克——更确切地说是沙特——仍在坚持己见,毫无下调生产配额的迹象。2015年这一情况是否会得以延续,仍有待观察。
