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 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.

It was Somerset Maugham who said the French Riviera is “a sunny place for shady people” – and looking around at all the 'models' in the hotel lobbies and the men in dark sunglasses who seemed to know them, I knew what he meant. Behind the festival's shiny facade, there is an unseemly side – and beneath the azure waters, a polluted mess. The French diver and environmentalist Laurent Lombard's video of the Cannes seabed strewn with waste and debris went viral before the festival began. We were assured there was no danger to swimmers, and the mayor had it cleaned up according to the Daily Mail – but the Med had certainly lost some of its sparkle.

In an industry enthralled to rehashed stories that strike a familiar chord with audiences, give Pixar credit for often trying something new and pushing their viewers into uncharted territories. Coco, directed by Toy Story 3’s Lee Unkrich, has a visual look based around Mexico’s Dia de los Muertos (Day of the Dead). It’s about a young boy named Miguel who idolises legendary guitar player Ernesto de la Cruz and wants to learn how to play as well as he could. So he goes on a transformative odyssey of self-discovery into the realm of the dead to find his long-deceased idol and learn some lessons about the nature of creativity and originality. Whether it can reach the heights of Pixar’s 2015 masterpiece Inside Out remains to be seen, but Coco should surely be a feast for the eyes. Released November 15 in France, November 22 in the US, Croatia and the Philippines, and November 30 in Israel. (Credit: Disney-Pixar)

The nearest star, Proxima Centauri, has a planet orbiting it not much bigger than Earth. Its "year" is only 11 days. But it's in the habitable zone because Proxima Centauri is a red dwarf star about 100 times fainter than the sun. And there's hot news that a similar star, 40 light years away, may have three planets in its habitable zone.
We will promote coordinated urban development above and below the ground, and begin construction on at least another 2,000 kilometers of underground utility tunnels in cities.

All these efforts will make our cities more attractive and function better.

My grandmother’s favorite poem was Invictus by William Ernest Henley. My father hung a copy of it on our kitchen wall, so I grew up reading it every day: “I am the master of my fate; I am the captain of my soul.” I think the best advice I can give anyone – especially someone just starting out in business – is to embrace your role as master of your own fate. Recognize opportunities when they arise and get comfortable saying “Yes.”

So until Brexit is formally complete in 2019, or an appealing alternative emerges, the Conservative party will keep her where she is. Remainers and Leavers alike wish to avoid a civil war that would be sparked by moving against her. What was thought to be an unsustainable position is proving surprisingly sustainable.

Friends wasn't known for being the most diverse show on television at the time, since the cast was comprised of almost entirely white actors.

The Mensa Supervised IQ Test can only be taken by children aged over ten-and-a-half and consists of two separate industry-standard assessments. One measures mainly verbal reasoning skills and the other, which includes diagrams and images, assesses visual and spatial logic.

She scored 142 in the second element, the Culture Fare Scale, with the results putting her in the top one per cent of the nation in terms of IQ. Anyone scoring a percentile of two in any Mensa test is admitted to the society.
