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.

Joss Whedon came up with the idea of Firefly while he was on a non-working vacation. He was reading a book called The Killer Angels which told the story of soldiers in the Battle of Gettysburg. Whedon was attracted to the idea of the difficulty of the soldiers' everyday lives. He liked that the author focused on the mundane details of how people survived when they didn't have all of their needs conveniently met by modern technology and commercialism.

Yet expectations for the summit meeting on Tuesday are low, with no sign of any political breakthrough that would lead to more ambitious efforts. Scientists say emissions must peak within the next few years, and then begin to decline, if the world is to have any hope of keeping global warming to an upper limit that countries agreed on five years ago. So far, no plans are in place that would come close to achieving that.

Have any franchise-leading duo reinvented themselves as spectacularly as Twilight’s Kristen Stewart and Robert Pattinson? Both have become art-house mainstays. Pattinson’s latest Good Time, keeps going his recent pattern of looking fairly unrecognisable. After he transformed himself with shaggy beard and spectacles in The Lost City of Z he now has bleach-blond hair as a bank robber who tries to pull off the perfect heist in New York City, only to get his younger brother (Ben Safdie), who suffers from a developmental disability, arrested for the crime. He tries to use the money he stole to post his brother’s bail, but complications ensue. Many complications. In addition to appearing as the younger brother, Safdie co-directs the film with his own brother Josh Safdie, and Good Time was selected to compete for the Palme d’Or at Cannes. Released November 3 in Japan, November 17 in the UK and Ireland and November 23 in Greece. (Credit: A24)
Little wonder, then, that Christie’s, the dominant player in the auction market for modern and contemporary art, is re-marketing its old master paintings as “classic art.” It will be offering old masters and other historical pieces next year at its Rockefeller Center sales in April, rather than January.
