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.

The first drone can be traced back to 1916 when British inventor Archibald Low designed and flew the first unmanned radio-controlled vehicle. The drone was made to counterattack German Zeppelin airships, and it also carried out ground attacks during World War I. It was made with wood and tin, its wings taken from the lower wing of another biplane. Overall, the drone was somewhat unsuccessful because the noise from its engine interfered with its radio. The Sopwith Aircraft Company also tried making a drone in 1916. They placed the radio equipment at the tail so that the engine would not interfere with its signal, but their drone never flew as it was damaged in an accident on the ground. Low would try flying his drone again in 1917 when he flew it in front of some senior military officers. It was launched from the back of a lorry and flew for some time before crashing due to engine failure, almost killing the military officers present.

“The auction market is extremely selective,” said Henry Pettifer, the head of old master paintings at Christie’s, whose sale total had been dented by a 15th-century Flemish Madonna and child by Hans Memling that the auction house had sold privately for more than 3.5 million and had withdrawn from the sale. “The availability of fresh material is limited,” he added, alluding to how few museum-quality works are in private hands.
“The consumer will take a little more time to come back which is why we’re focusing on a game plan we know that works, focusing on affordability and premium [drinks] in metro areas,” he said, adding that he is confident that the company can continue to gain share in the country and is set up for when consumer spending picks up again.
