The Feynman Lectures on Physics have become a long time classic amongst science students around the globe. Last year Bill Gates announced that he had purchased the rights to videos of seven lectures that Feynman gave at Cornell University in 1964 called “The Character of Physical Law”. Microsoft has created a project web site called Tuva that is intended to enhance the videos by annotating them with related digital content. You can watch the videos for free.

If you are wondering why Microsoft has named its project ‘Tuva’ – after a small republic in Siberia, with its capital Kyzyl located near the geographical center of Asia – the following documentary about Feynman made by his good friend Ralph Leighton is definitely a must-see. It is a very personal portrait of a curious mind at large, an explorer, a drummer, a painter, a singer, a teacher, and a scientist who would have preferred to renounce the Nobel prize in 1965 (“I didn’t like the publicity beyond.”), and who died to early to fulfill his last journey.
