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

But the struggle for white identity is not just a political problem; it is about the “deep story” of feeling stuck while others move forward.

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 the first "real" James Bond song (again, the first two films only opened with orchestral music), and it's still the best. Shirley Bassey got an opportunity to sing her soul out and she accepted the challenge with obvious pleasure. This is a song that makes the villain Auric Goldfinger seem a lot more threatening (and attractive) than he actually is, but that's part of the miracle of Bassey's work here. It's proud and heroic and enticing and it's kind of a lie, but who cares? The music is pure James Bond, the lyrics are pure machismo, and the performance is perfect.

What is the relation of effect to cause?) is both a charming, newly rediscovered artifact of its hectic time and a bulletin from the cinematic future. Everything has already been done, and everything is still possible.

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.

The artificial ear then just needs a few days growing in nutrients before it's ready to be implanted in a subject.

I am acutely aware now that in my pursuit of perfection at work, I have often failed to recognize that imperfections are also a core part of our identity that needs to be preserved and not always changed.
