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.

But researchers this year came up with a new method that makes flexible, realistic ears out of real cells. Those cells come from rats and cows, and they form a collagen gel that can take the shape of any mold. When placed in a mold of a human ear—a mold assembled using a 3-D printer—the gel forms an ear in less than an hour. The artificial ear then just needs a few days growing in nutrients before it's ready to be implanted in a subject.

This technology previously existed for arms, but legs are rather more complicated. And since a misread signal can send you jumping off a bridge or in front of a moving car, thought-controlled legs need more stringent programming than equivalent arms. As one of the researchers delicately put it, “If you're using a bionic arm and it misbehaves, the elbow may move slightly. If the prosthetic leg misbehaves . . . that could be quite a safety issue.”

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.

The armistice famously went into effect at "the eleventh hour of the eleventh day of the eleventh month."
