In between trying to eradicate polio, tame malaria, and fix the broken U.S. education system, Gates has managed to fulfill a dream of taking some classic physics lectures and making them available free over the Web. The lectures, done in 1964 by noted scientist (and Manhattan Project collaborator) Richard Feynman, take notions such as gravity and explains how they work and the broad implications they have in understanding the ways of the universe.
Gates first saw the series of lectures 20 years ago on vacation and dreamed of being able to make them broadly available. After spending years tracking down the rights--and spending some of his personal fortune--Gates has done just that. Tapping his colleagues in Redmond to create interactive software to accompany the videos, Gates is making the collection available free from the Microsoft Research Web site.
