CNET News: Microsoft billionaire Bill Gates has managed to fulfill a personal 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 explain how they work and the broad implications they have in understanding the ways of the universe.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.
