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

Based on a new estimate provided by the government of Dubai, its visitor spending of $31.3 billion this year far exceeds London's estimated $19.8 billion, which comes second.
Chinese mainland is home to two of the top three universities in Asia, according to research published last Thursday by the Times Higher Education (THE).

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.

But the UK courts may land a heavy blow on ride-hailing app Uber. In 2017, the California-based company failed to persuade an appeal judge that two of its London drivers are independent contractors. In 2018, the test case will go to the Court of Appeal and possibly to the Supreme Court. If Uber loses the case and is told to assume the responsibilities of an employer, the implications will ripple far and wide.

This groundbreaking fight is loosely based on a bout between Chuck Wepner and Muhammad Ali, in which the "everyman" Wepner managed to become one of the four men to knock Ali down in his career. Just like in the film, Wepner pushed Ali through 15 rounds despite looking (and feeling) like he'd been hit by a truck. While both he and Rocky ended up losing their fights on a technicality, Wepner wins in our book for inspiring such an awesome character.

It was apparent not just in obvious brand extensions, like Banana Republic’s “Mad Men” collection (designed in collaboration with the show’s costume supremo, Janie Bryant), but in more pervasive, unspoken ways: in silhouette and print; in hemline and seam. And in the clear belief, visible on catwalks everywhere, that the 1960s were the answer to every moment of pallid inspiration, or aesthetic doubt.

Graham Allison, the famous Harvard professor, also warned that east Asia was headed towards the “Thucydides Trap”, adding: “When a rapidly rising power rivals an established ruling power, trouble ensues.” In early 2013, the then prime minister of Luxembourg, Jean-Claude Juncker, warned that 2013 was looking dangerously like 1913. The Economist also warned at the end of 2013, “A century on, there are uncomfortable parallels with the era that led to the outbreak of the first world war.”
At the center of the speculation is BlackBerry’s healthy intellectual property portfolio, 44,000 patents and still growing.

Security continues to be BlackBerry’s biggest selling point with businesses.

Market watchers were forced to digest the reality of negative 2.9% GDP for the first quarter of the year. All of a sudden, everyone’s forecasts seemed too rosy—or at least too smooth—compared to the lumpy reality. This led to a raft of second-guessing on the timing of the Fed’s eventual exit from its bond-buying stimulus program. We went from confidence to WTF? in a space of a few weeks, with all the asset class rotations and market corrections that come along with a fresh bout of uncertainty.
