Professor Jim LaBelle disucsses the Foucault's Pendulum that swings in the atrium of the Fairchild Building on the Dartmouth campus.
The Messenger Lectures include seven videos of Dr. Richard Feynman speaking on physics at Cornell University in 1964. The videos are here presented in Microsoft’s Project Tuva (requires browser plugin download), which enhances the videos with closed captions, note-taking capabilities, links to related resources, video navigation functions, and more. The lectures are excellent (each of the seven videos is over 45 minutes, but less than an hour) and Project Tuva is an interesting new tool.
