Became a Maths godfather accidently

Nadia, niece of Salman Khan has done poorly in mathematics and asked him to assist her. For Khan in that time, 28, maths is his strength because one of his major was it in MIT.
They`re not in the same city, he taught her through internet, under his vivid and clear explanation, Nadia` s maths score upgraded rapidly, more people coming to find him.
Later, Khan thought why not make a video to play on internet and watch it for free. Then he buried himself at home starting to make the video. Over one year` s recording, from primary mathematics to calculus then to advanced mathematics, he presented totally.
All of the videos got a huge achievement on the internet, over 500 million click rate and 48 million people watched. In the United States, over 20 thousand of school teachers won` t give maths lessons. Students watch Khan` s video, teachers are just responsible for answering questions.

Refuge $1 billion dollar

After his achievement, lots of venture capital companies found him wishing to register a company and charging to these videos which means Khan will become a very rich man with million dollars immediately! But, he refused. He` d rather be a middle class and just accepts donation never charging. He said: “I just want to do the free education, once it charges, lots of children from developing countries cannot afford it. I cannot imagine what will be more meaningful than that in my life for now.” In March 2011, Khan made a speech in TED in California, all of audience stood up and applause. Bill Gates, Khan` s craziest fans, went up onto the platform on the spot to communicate with him about his item. He used to spend a lot of time teaching 3 kids basic concept of mathematics and science, but they all muddled, until the beginning of 2010, someone recommended Khan` s video, unexpectedly, only 12 minutes video can explain clearly and make kids digested what he never put across before. Gates said frankly, “I` m really jealous of him”.
While Khan` s idea is very simple: I` m a teacher behind the video and also a dad, my kid is same like the children all over the world whom need to be well educated and accompanied.
