I am a huge fan of Richard Feynman. The QED God also happened to be a great educator, motivating many people with his books and interviews! I have uploaded a 50 minute vdo of his to Google and he talks about the sense of pleasure one attains when he or she figures out how a certain thing works. I think I don’t have to say more about the man, since most of you folks would be familiar with him! I will let his video do all the talking! The video is titled, “Pleasure of finding things out”, and was broadcast on BBC TV as part of their Horizon series. Here is the link to the original production company where you can also find info about other documentaries and order the DVD’s.
