Links explained

Links (besides the ones whose titles are self-explanatory):

• MIT opencourseware: MIT is making available gratuitously online the material for its courses, so you can have a look at the homework, tests, and class material and try to follow it yourelf.
• Huygens'-Fresnel Principle in Superspace: is a paper I wrote on the transposition to superspace (the configuration space for a dynamical setting of G.R.) of a principle that better accounts for light diffraction and interference than Fraunhofer diffraction (which is valid for large relative distances between aperture and screen).
• Edge: is a site where leading intellectuals from many areas try to explain accessibly to each other their current work. Very recommended.
• Beyond Belief: Was a conference held in 2006, held to discuss the interaction between science and religion. Attended by such figures as Steven Weinberg and Richard Dawkins, the site holds videos of all the sessions. Truly interesting.
