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

During last year's LFW, there were 250 anti-fur protesters, The Guardian reported, and a show in February saw an activist storm the stage at a Mary Katrantzou show.

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.

So the messaging apps have gotten creative. Tango, for example, inserts ads within a user’s messaging “inbox.” WeChat, a popular Chinese app that is owned by Tencent, makes money through games, stickers (which are similar to emojis), and mobile commerce. Kik offers a feature that some are calling “chatvertising,” where users hold conversations with chat-bots powered by brands like Funny or Die and Moviefone.

The first wearable computer glasses were made by Edward Thorp and Claude Shannon in 1961. In 1968, Ivan Sutherland made the "Sword of Damocles." It was the first head-mounted computer display and an early variant of all wearable computer glasses we have today. In 1980, Steve Mann, known today as the father of wearable computing, made the "WearComp", a pair of tech-enhanced glasses that was capable of communicating wirelessly with other computers and could share videos. He continued to work on the glasses over the years, and by 1999, he had come up with a pair of glasses that looked like Google Glass, or rather, that Google Glass looks like. He called it the "EyeTap."

James Gorman, a Times reporter, accompanied scientists who are trying to understand the genes that distinguish dogs from wolves. Humans who raise wolf puppies must spend 24 hours a day, seven days a week with them in order to socialize these puppies for scientific study. And while the pups may seem cute, they will grow to be predatory wolves, not humanity’s faithful companions. The researchers hope their work will help reveal the trigger that made some ancient wolves into the dogs we know today.

The film pulls heavily from the life of Arthur Bremer, who shot presidential candidate and segregationist George Wallace in 1972. Similarly to his film counterpart, Bremer shot Wallace shortly after being rebuffed by a young girl. Overall, though, his life was much less exciting than that of De Niro's character, with the biggest commonality between the two being that neither actually succeeds in killing a politician.

It even featured in the March 19, 1870, issue of Scientific American magazine. Made by Thomas Luders from Olney, Illinois, and called a "pedespeed," the wheels then were much smaller, measuring around 36 centimeters (15 in) in diameter. Luders also said the skates could be used by anybody, irrespective of their physique. He himself was a large, heavy man, and he claimed he could use them for two straight hours without getting tired. Another version of wheel skates, appearing in 1923, had its tires on the inside of the foot rather than outside. (Other than the size of the wheels, the main improvement made by Chariot Skates is the small tire at the back of the bigger tire for increased stability.)
