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

Logan's claws are slow on the draw and his self-healing powers are on the fritz, but he's committed to caring for his mentor Charles Xavier (Patrick Stewart, so good you want to applaud). It's not easy watching Professor X suffer seizures that rattle his telepathic brain. Make no mistake, Logan earns its tears. If Jackman and Stewart are serious about this being their mutual X-Men swan song, they could not have crafted a more heartfelt valedictory.

In early 2005, Stone and her co-founders Elisa Camahort Page and Jory Des Jardins noticed that there were countless women blogging, but mainstream media rarely linked to their posts. The trio decided to host a grassroots conference that year and attracted sponsors like Google and Yahoo. It quickly sold out and soon after, they launched BlogHer.com. The publishing platform turned blogging into a lucrative business for many women -- it paid $25 million to 5,000 of its bloggers between 2009 and 2012 -- and now reaches an audience of 92 million.
Consumer prices rose 2.3 per cent year-on-year, more than expectations of 1.8 per cent. That is the biggest rise since July 2014. They had risen 1.8 per cent in January.

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.

Episodic memory is also known as long-term memory, and the researchers approached the study of exercise in a different manner than previous studies. Other studies examined the impact of aerobic exercise conducted over many months, but this study simply asked participants to lift weights a single time. During the test, half of the participants were asked to use a weight machine before recalling a series of images they were shown at the start of the test. The other half of the participants were also asked to recall the images but without having engaged in any strenuous activity before the recall session. In demonstrating the memory improvement for the participants who engaged in just a single session of weight lifting, the researchers were able to show that improving one's memory through exercise didn't take hours of dedication in the gym. The next time you have the opportunity to lift weights or someone tries to convince you to join the gym you might just want to take him or her up on the offer.
But that moment, try as Google might, has yet to come.

In my adolescent years on the foothills of Himalayas, I had a friend we all referred to as the "dreamy guy." He would spend his days enjoying the smallest of things – color-tagging butterflies, counting peaks on the horizon, making stories out of cloud formations. He was a happy soul, deeply receptive to life's beauties and easily excited. I knew this guy many years ago and I thought about him today as I sat down to write this piece for you, dear class of 2013.

Aspiring young leaders already place more emphasis on using their influence, rather than trying to exert power through the embedded authority of their position or their assigned title. Many are already gaining leadership experience, not through promotion at established institutions but by running bottom-up movements and voluntary groups, or by shaping their own start-ups.

Taken together, these events and strategic initiatives highlight the Chinese aerospace industry’s realization that, in order to become a globally competitive player, it will need depth as much as breadth. After getting their hands on both ends of the value chain—aircraft design and final assembly—the Chinese now understand that what will make or break their industry over the long term is what happens in the middle of the value chain, at the component and subsystem levels. And that is why China’s ambition to compete with Boeing and Airbus, as well as with GE and Rolls-Royce for aircraft engines, is now more credible than ever.
