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

以美元计,上个月进口下跌了18.8%,跌至1141.9亿美元,跌幅超过了去年12月的7.6%,也超过了下跌3.6%的预期。
欧洲出现了债务危机。日本面临自然灾害。曾经是全球亮点的新兴市场也失去了光芒。近来意大利、埃及和泰国等国频现政治危机,这或许表明全球市场可能将出现新一轮动荡。
Shanghai Pudong International Airport reported the lowest punctuality rate last year. Only 52.4% of flights took off on time, with delays averaging 48 minutes.
毫无疑问,全世界的肠胃病学家都会感谢Emmanuel Ben-Soussan和Michel Antonietti,因为他们的研究给出了医生该如何进行结肠镜检查的推荐,从而让他们的病人发生气体爆炸的可能性降至最低。
麻省理工学院斯隆管理学院(MIT Sloan School of Management)教授迈克尔?库苏马诺(Michael Cusumano)表示:“我曾经认为乔布斯是不可取代的,而且这在一定程度上是个事实。但乔布斯的精神依然留存在苹果内部,而且公司正围绕着一种不那么对抗性的文化组织在一起。我们应为此给予蒂姆赞扬。”

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.

This pseudo-comedic 1970s crime drama tells the story of two romantically involved con artists named Irving Rosenfeld and Sydney Prosser, who are caught by an FBI agent and forced to scam corrupt politicians. The two continue to manipulate the FBI agent, their political targets, and their own family members, ultimately cutting an immunity deal that allows them to escape the ordeal without any criminal charges.
Coca-Cola is in the middle of transforming its business as it sells off its bottling operations in the US and across the globe to focus on producing the concentrate that makes many of its drinks as well as research and development. Those sales will allow the company to focus more of its resources on innovation and acquisitions.
中国拥有世界上最大的外汇储备,它一直被视为金融稳定的最终保障,因为外储可以被用来对冲资本外流,或纾困艰难应对坏账增加的国内金融机构。
今年最令人惊喜的消息还包括油价下跌。经济学家对油价下跌的经济影响也是见仁见智,一方面认为消费者因此节省了不少油钱,一方面则认为这种趋势会影响石油的开采钻探活动。但大家普遍认为这会影响小型车和混合动力车的销量。油价下跌加上车价过高,使得凯迪拉克公司的电动轿跑ELR稳居2014年最不受欢迎的车型“宝座”。11月份,这款售价高达8万美元的电动跑车只卖出了155辆。

“We will see a lot of headlines about [emerging market export growth] picking up in the first half of 2017,” says Bhanu Baweja, head of EM cross asset strategy at UBS, who believes EM exports will show year-on-year growth of between 8 and 13 per cent in dollar terms in the first quarter of this year, “a complete postcode away” from the negative numbers currently being reported.

Murietta belonged to a gang known as the Five Joaquins, who were notorious bandits during the height of the California Gold Rush. While Murietta's criminal activity likely did not have any political undertones, he nonetheless became a symbol of Mexican resistance as American settlers ventured to California. Unfortunately for him, this pushed the government to put a bounty on his head, leading to his murder and beheading. Luckily, Banderas's character didn't fall to the same fate.

Welcome, and before we begin – please accept our apologies. Your four-hour nightmare wait at passport control should not be taken as a symptom of Britain's contempt for foreigners.

Don't worry, they hate us too.

Since the establishment of Avic 1 and Avic 2 in 1999, which really marked the beginning of China’s push into the commercial aerospace market, there has been no doubt about China’s intent and the direction it wants its industry to take. But the pace at which it would achieve this ambition was less uncertain. Almost 20 years on, things have become much more clear, and there is now little doubt that China is well on its way to succeeding where several other countries have failed in becoming a full-fledged player in the large commercial aircraft manufacturing sector, with the potential to disrupt the long-standing duopoly of Airbus and Boeing.

The bigger Tesla gets, the more complex its operations become. Since it sells directly to customers and eschews franchised dealers, it will have to develop a network of service centers to handle repairs on the cars it sells. Its unusually generous warranty, which obligates it to buy back used cars for 50% of their original base price after three years, could create a second channel of used Teslas. “Tesla will be eating a lot of three-year-old cars that aren’t as sexy or rare as they were a year ago,” wrote one Seeking Alpha blogger. ‘To me, it sounds like a potential mess.”

People with near-perfect memories actually exist, and they have something called an "eidetic memory," which means they can recall a remarkable amount of information from their past experiences. Interestingly, many people assume having an eidetic memory means having a "perfect" memory, but even these superhuman memory machines can have some trouble recalling absolutely every detail with crystal clear accuracy. However, that doesn't mean you can't emulate these memory superstars and improve your own memory and protect yourself against age-related diseases and maladies.
