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

Bond King Bill Gross admits, 'QE must end.' Trillions of cheap money 'has distorted incentives and inflated asset prices to artificial levels.' But now Gross says 'the Fed plan may be too hasty.'
Brands with the most incentive to coast in 2015:Jeep, which must be exhausted after lifting sales an astonishing 44% on the back of the new Cherokee, and Subaru, now the 10th most popular brand in America after improving its sales by 21% in its usual fashion: quietly.
But what will politicians actually do While President Trump is focused on bringing back traditional manufacturing jobs to America, different US states are experimenting with other policies to help low-paid precarious workers. These range from sharply higher minimum wages to new rules to stop employers changing staff schedules at the last minute.

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.

Historical and fictional films each have their own strengths when it comes to storytelling. Every now and then, though, movies pop up that don't quite fit into either category. The stories are wildly unrealistic, but they carry an inkling of truth between their pages. While these are some of the most interesting films out there, viewers often don't even know that what they're watching really happened. Well, wonder no more!

5. Geopolitical flashpoints.In the not too distant past, a small supply disruption would send oil prices skyward. In early 2014, for example, violence in Libya blocked oil exports, contributing to a rise in oil prices. In Iraq, ISIS overran parts of the country and oil prices shot up on fears of supply outages. But since then, geopolitical flashpoints have had much less of an effect on the price of crude. During the last few weeks of 2014, violence flared up again in Libya. But after a brief increase in prices, the markets shrugged off the event. Nevertheless, history has demonstrated time and again that geopolitical crises are some of the most powerful short-term movers of oil prices.
