Comments from students:
btw, i hope you get something REALLY great from life for helping so many people out here. like.. i dont know, foreverlasting happiness, neverfailing health and a wealthy life. if there is someone who deserves to have it all, it is you sir.
You have no idea what contribution OPEN SOURCE EDUCATION represents to people without the luxury of the education you take for granted. Spoilt with scant knowledge of the 'outside' world, I am genuinly suprised to find such a narrow minded individual on a science channel. Do folk find you self-centred and egotistical? Wake-up sunshine you stiffling your own contribution and evolution of self. Big up to the Khan Acadamy and anybody who appreciates their worth.
