Physics

A couple of physics-related things you might find interesting:

• for a nice stroll through the problems, challenges, and possibilities of today's high-energy physics, read Michael Dine's article in the December issue of Physics Today: String theory in the era of the Large Hadron Collider.
• John Baez has a nice explanation of what Krauss and Dent really meant in their paper, as opposed to what New Scientist reported they meant.
