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

Widely misunderstood as a biopic about the novelist David Foster Wallace, Mr. Ponsoldt’s film is a comedy of journalistic bad manners and a bitter, knowing satire of the machinery of literary fame. Jesse Eisenberg and Jason Segel use the conventions of the buddy movie to perfect a new subgenre: the frenemy film.

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.

We'll start our review with the South American nations, and who else could we begin with, but the hosts Brazil. Rewind 18 months and they looked like they'd be struggling, but the appointment of 'Big Phil' Scolari has been inspired, and he's brought a belief to the team that was previously missing. Last years 3:0 demolition of Spain in the Confederations Cup final shocked many experts, and all of a sudden the Brazilians have expectations on them. Whilst you can't argue with that scoreline, we still wonder if Brazil have the firepower to win such a long tournament. Neymar is expected to conjure up the magic, but they're relying on Fred to come up with the goals. No disrepect to Fred, but the last two Brazilian teams to win the World Cup, in 2002 and 1994, could count on the likes of Ronaldo and Romario to lead the front line, two genuine legends of the game.

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.
