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

? Ten of a reported 33 fatalities occured in New York City, and that number was expected to rise, according to Mayor Michael Bloomberg. Deaths in New York were attributed to falling trees, electrocution and drowning.

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’s not clear which group of Dutch lenders was wrong. It’s possible that the Seppenwolde lenders ignored the evidence about broader financial conditions and were too pessimistic. It’s also possible that the other lenders were too casual in brushing off the implications of the East India mess. Either way, the Dutch episode suggests that even sophisticated investors become optimistic or pessimistic for myopic reasons.

Remedy: The tricky aspect of this regret is that it’s typically rooted in hindsight. Only after you’ve left the job and have moved on to something better, do you start beating yourself up for not making the leap sooner, even if it hadn’t been practical or possible. What you can do is to identify the factors that kept you in your former position as red flags to be aware of in the future and work to line up supports that will allow you to more quickly capitalize on other opportunities as they may present themselves. This could include reviewing and updating your resume with new accomplishments on a monthly or quarterly basis, keeping your LinkedIn account current, building up a contingency fund to allow you to feel less tethered to your current pay check and staying in the loop on industry news and gossip to be aware of where your skills and experience could be of value.
Released in 2013, The Bling Ring is a satirical crime drama that chronicles the adventures of Hollywood Hills high schoolers who burgle the homes of local celebrities.

Argentina, the host nation's big rivals, are in with a great chance too.

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.
