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

两周后,伯恩海默等几十位著名的早期绘画大师作品交易商出席伦敦的夜间拍卖会。过去,他们通常会在这些拍卖会上购买一些作品,以备在第二年3月的荷兰马斯特里赫特欧洲美术博览会(Maastricht European Fine Art Fair)上展示。但是由于卖家们鼓励苏富比和佳士得报出更高的估价来争夺自己的拍品,所以拍卖行只针对少数富豪进行宣传,现场竞价十分冷清。

Brazil lost that 1950 final, 2-1, to Uruguay, a historic humiliation that still stings Brazilian fans today. Belmonte, 85, hopes he'll get to see his country regain its honor. "I hope Brazil will be able to win this time," he said. "This is our revenge. I want to go see our revenge."

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.

The second-best song that Shirley Bassey performed for the James Bond franchise is still one of the best. For a series that, on some level, has always been about wish fulfillment, listening to one of the great singers belt powerful notes about avarice seems just about right. So say what you will about the film (it's not on many of the lists of James Bond's best), but Bassey had good material here and she knocked it out of the park.

As the stars' private jets swooped in, the internet was going mad for 'the Dad bod'; the slightly flabby male physique was trending and there were plenty of examples on screen. Deborah Cole of AFP noted a “sweating, panting and shirtless” Gerard Depardieu in Valley of Love and a flash of Joaquin Phoenix's “tubby tummy” in Woody Allen's Irrational Man. When Colin Farrell strode the red carpet for the premiere of The Lobster, he looked his usual trim self – but in the film he is distinctly paunchy. To add some girth for the role of a lonely singleton in Yorgos Lanthimos' absurdist black comedy, Farrell went on a massively calorific diet that included drinking melted ice cream, he told the Hollywood Reporter. Eating “two cheeseburgers, fries and Coca-Colas, and two slices of chocolate cake at 10am is not that fun,” he said. “And I love cheese?burgers."

No one since Michael Haneke has enjoyed cinematically dissecting social conventions as much as Greek film-maker Yorgos Lanthimos. His The Lobster took Cannes by storm two years ago with its scathing look at a society that turns adults into animals if they cannot find a romantic partner within 45 days – it was our world but pushed toward the outermost limits of groupthink and conformity. Now he’s back with The Killing of a Sacred Deer, a domestic thriller about a surgeon (Colin Farrell) and his wife (Nicole Kidman), also a doctor, who befriends a fatherless teen named Martin. The boy seems determined to expose the family’s secrets and unmask a terrible trauma from their past. Is this film about how domestic (and perhaps societal) tranquility sometimes depends on shared, agreed-upon lies? Either way, prepare to be unnerved. Released November 9 in Denmark, November 16 in Russia and November 30 in China's Hong Kong. (Credit: A24)

Housing is finally recovering. Home values are up 7% nationally through the first nine months of 2012, according to the S&P/Case-Shiller index. Meanwhile, home-building is gaining traction, which means more jobs for construction workers, contractors and builders. Some 29,000 new construction jobs have been added since May. There's 'a significant thawing in labor conditions in the construction market,' notes Andrew Wilkinson, economist at Miller Tabak & Co. It's not just construction crews. Retailers who cater to Americans furnishing, repairing and improving their homes also will need to hire.[qh]

o Battery power may turn out to be a transition technology. Cost reductions have been slow in coming, and Tesla needs a 30% improvement in order to build the $35,000 Model 3 it has promised for 2017. Toyota’s recent move was eye-opening. It is allowing a battery-supply deal with Tesla to expire and instead will redouble its work on hydrogen fuel cells. The cost of fuel cells is coming down faster than batteries and fuel cell proponents believe drivers will prefer a relatively rapid refuel with hydrogen to waiting hours to recharge their batteries.
