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 standout is "Him," a tear-jerker about queer love and cultural intolerance that, in its understated way, is an LGBTQ civil rights anthem.

Similar trends have been seen at other Cup matches, though no polls were carried out previously.
Ahead of this year's fashion week, set to take place September 14 to 18, an open letter written by singer Paloma Faith and published by Peta also called for LFW and the BFC to ban animal fur.

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.

007电影中,反派人物往往没有自己的主题曲,但是《金枪人》中克里斯多弗·李扮演的暗杀者出场时有一段轻快动人的绝妙曲调,衬托出暗杀者如地狱使者般帅气冷酷。LuLu的演唱完全演绎出这个反派斯卡拉孟加的过人之处。即使这首歌在今天来说欢快得有点可笑,但这也增添了它的魅力。

Wheel skates look somewhat like regular inline skates, except that the wheels are much larger, up to the size of bicycle tires. They are seen as a cross between an inline skate, a ski, and a bike. Recently, a company called Chariot Skates said they had come up with something unique—the Chariot wheel skates. According to the company, wheel skates are "revolutionary new skating products." Revolutionary? They do at least revolve. New? No. The first wheel skate was made more than 142 years ago.

Alfonso Cuaron and his colleagues, most notably the cinematographer Emmanuel Lubezki, the production designer Andy Nicholson and the filmmaker's co-writer, Jonas Cuaron, have made a motion picture that expands the way motion pictures will be made. Readers with an interest in technology can get a sense of their extraordinary achievements from last month's cover story of American Cinematographer, which is available online. But the emotional essence of the film is already known to anyone who has seen it, and has been swept away by it-into the outer space of silence and menace, into an inner space of deep delight.

Rounding out the top-performing sectors of 2014 was an unlikely pair: tech (+16%) and consumer staples (+13.2%)—the most aggressive and most defensive areas of the market, running side-by-side toward the finish line, with confounded spectators struggling to concoct a narrative for this. Why would the least cyclical sectors—healthcare, staples and utilities—lead the markets in a year in which unemployment plummeted and GDP growth gained momentum? Much to the chagrin of the pundit class, sometimes there are no satisfying answers. To quote Kurt Vonnegut:
Last week, Clinton campaign chairman John Podesta said that the former first lady's shortlist of potential running mates will include women, quickly leading to speculation that Clinton will consider Massachusetts Sen. Elizabeth Warren, a popular progressive, for an all-female ticket.

Domestically, an increasingly active middle class is generating pressure for more accountable governance. Mounting inequalities have nurtured a sense of injustice; 200m migrant workers remain second-class citizens and corruption is worsening. Tackling these problems is urgent, but China's economic successes have fostered an unwarranted self-confidence. Instead, motivated by the Arab spring, the system has moved aggressively to contain any social discontent that might spark more politically sensitive movements.

Remedy: Make a budget. If you don’t know how much money you need to live the lifestyle you feel comfortable with, you can’t accurately project whether switching jobs for a $10K pay bump is actually a good deal. Making a pros and cons list when comparing your current job with a new opportunity is also helpful. If the only advantage a job offers is a bigger pay check, you can weigh that against longer hours, a more onerous commute and increased reporting responsibilities. Keep in mind that research shows that increases in happiness based on earnings peak at about $75K. Incomes above this level don’t increase your feeling of well-being on a day-to-day basis. So, if you think a jump up to $85 or $90K will make you feel less morose when your alarm goes off, you might want to look at addressing some of the non-monetary factors in your life that are contributing to your dissatisfaction.
