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

Local residents living near the launch sites have complained that the activists are putting their lives at risk by making them potential targets for North Korean retaliation.
That is up from a rise of 11.2 per cent in September.
However it's framed, 2018 was a strong year for many of China's biggest domestic film studios though.
在接下来的几个月里,金州勇士就恢复正常了。因为凯文·杜兰特受伤,让斯蒂芬·库里重新成为那个无所不能的斯蒂芬·库里,当凯文·杜兰特重返球队的时候,球队也在他们这两个MVP之间找到了平衡。于是季后赛横扫西部的可怕爆发显然可以预料得到。开拓者被打的毫无还手之力,爵士拼尽全力但仍无法获得一场比赛。本来马刺很有可能拿下一场比赛,在那场比赛中他们一度领先20分,然后,当扎扎帕楚里亚垫了一只脚之后,科怀·伦纳德便受伤了,结果就是这样。

“只要总体市场仍然相对积极,只要交易继续执行良好,我们继续预期今年余下时间会保持健康的交易量,”高盛(Goldman Sachs)美洲股票资本市场主管戴维?路德维格(David Ludwig)表示。

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.

And while you are at it, don't forget to celebrate the imperfections. While on a 10-day trek in the Himalayas, I learned that imperfections are beautiful too. The rough edges of the mountains, the heavy hail storms in the middle of the afternoon, were "inconvenient" but added to the beauty of the trek. I am acutely aware now that in my pursuit of perfection at work, I have often failed to recognize that imperfections are also a core part of our identity that needs to be preserved and not always changed.

自迈克尔?哈内克之后,再没有人像希腊导演欧格斯?兰斯莫斯那样喜欢在电影作品中解剖社会习俗了。两年前,他的电影《龙虾》用其看待社会的辛辣视角完全征服了戛纳电影节。在《龙虾》描述的社会中,如果成年人无法在45天内寻找到一个爱侣,就会变成动物——这也是我们的世界,只是将集体思维和从众性推向了最大的极限。如今他又带着新作《圣鹿之死》回归,这是关于一个外科医生(科林?法瑞尔饰)和他的妻子(妮可?基德曼饰)的家庭惊悚电影。这位妻子也是一个医生,她像朋友一样对待没有父亲的少年马丁。马丁似乎决心暴露这个家庭的秘密,并揭开这对夫妻过去的一段可怕的创伤。这部电影想表达的难道是家庭(也有可能是社会)的平静有时候依赖于共享商定的谎言?不管是不是,准备好接受惊吓吧。该片将于11月9日在丹麦上映,11月16日在俄罗斯上映,11月30在中国香港上映。(A24制片公司)

Mr Koepke argues, however, that the role of US interest rates in provoking EM crises has not been fully understood. He presents evidence that the probability of EM crises is substantially higher during a conjunction of three conditions: during a Fed tightening cycle, when the federal funds rate is above its natural rate (the rate that leads actual output to converge to potential output), and when market participants are surprised by signals that the Fed will tighten policy faster than previously expected.
