I live in third world country, and universities are ludicrous. I have said this repeatedly, but I want to say that again because education is <i>the</i> important thing in the world in my opinion, and free lectures&#x2F;education is just like discovery of fire in human history.<p>If I were to choose prophets for humanity, I would choose the people who provide free <i>scientific</i> material for humanity.<p>Not a bunch of schizophrenic from 14 or 20 century ago.<p>For those who live in developed country maybe you cannot realize how much impact can a simple series of lectures can have on students on third world country. I live in third world country, I can see with my own eyes how can it change people mind.
