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 exchanges revealed there is little major difference between the two in term of their approach to security and foreign affairs. On Iran both vowed it will not be allowed to have nuclear weapons. Rommey said he would introduce more stringent sanctions; Obama said they were already as stringent as they could possibly be.

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.

In 2017, his 14th season in the league, LeBron James averaged a career high in assists and rebounds. In the first two months of 2017-18, he's averaging a career high in 3-point percentage, but that's been talked about and dissected; it's been written about extensively.
'Cutie and the Boxer' was hardly noticed by the movie-going public, but a list of fine films isn't a rundown of box-office triumphs. The reach of Zachary Heinzerling's debut feature-length documentary is equaled by its grasp. On the surface it's about nothing more-or less-than a troubled marriage that has somehow managed to last 40 years. Beneath the surface, then startlingly out in the open, is a history of rivalry (both husband and wife are artists), enmity, reluctant devotion and, most startling of all, enduring love.
China purchased 141,000 industrial robots in 2017, up 58.1% year-on-year, but foreign brands accounted for nearly three quarters of that, showing that the gap is still widening between Chinese robot makers and their foreign peers.

With the majority of professional advisors (myself included) preaching the benefits of global diversification to their clients, 2014 looks more like a draw than an outright victory in the harsh light of December’s low winter sun. Consider the fact that, through last week, the MSCI World Index gained just 2% on the year, with nearly 5% drops for both the MSCI Emerging Markets index and the EAFE index of developed markets outside of the United States. Ironically, the single best-performing foreign market in the world, the Shanghai Composite of mainland Chinese equities (up 45%) is the only one that U.S. investors could not actually put their money into.

除了这些理论之外,还有传统经济学家用来误导美国的坏的统计数据:最恶劣的是GDP,它在衡量美国长期增长的时候是一个狭窄的、误导人的指标。其次,我们对短期数据(每日收盘情况、季度业绩、年度回报等)的执迷正在阻碍美国的长远增长。

Will Smith had a very successful career in the late 80s and early 90s as the second half of rap duo DJ Jazzy Jeff and the Fresh Prince. But in spite of his financial success, Smith did not manage his money well. It's a pretty classic tale, really. New fame, lots of money, no future plans, and lots of fancy toys added up to a lot of overspending. This lack of oversight and fiscal irresponsibility landed him on the brink of bankruptcy. He owed the government back taxes that he had not paid.

不会。随着美联储收紧货币政策并扩大美国与日本的利率差,2018年日本央行的日子会更不好过。但是日本央行行长黑田东彦(Haruhiko Kuroda)已决心只会因一件事而上调利率,那就是通胀。如果通胀开始加速,日本央行可能会让收益率曲线略微上扬,但到2018年年底时日本实际利率不会高于年初时的水平。

Collins grew up in rural, apartheid-era South Africa in the 1970s. Her childhood inspired her to focus on empowering women living below the poverty line through grassroots efforts. The Wonderbag, which was inspired by watching her grandmother cook with cushions, uses heat retention technology to cook food for 8-12 hours without the need for additional fuel. Collins witnessed the benefits African women received from using Wonderbags, reducing the amount of time they spent collecting firewood. For every bag sold, another is donated to a household in Africa, and in the past four years, the Wonderbags have found themselves in 600,000 African homes. Collins has launched the Wonderbag in the U.S. on Amazon, and hopes to sell the products via other retailers by 2014.
Though its campuses often steal the benefits spotlight -- with their outdoor sports facilities, free food and more -- there's a more morbid perk that should certainly be noted.
