I just now learned that my friend Ravi Ramakrishna from Cornell spent a sabbatical term last spring at the Kigali Institute of Science and Technology in Rwanda. And he blogged his semester. Good reading for anyone interested in math in the developing world, or who likes awesome pictures of gorillas and volcanoes. Ravi made a side trip to Uganda with Teach and Tour Sojourners; seems like a nice program, though note that you pay your own way to the continent.

Note: I don’t know if Ravi actually deformed any Galois representations while in Rwanda. But come on, if you know the guy, you know he probably did. He can’t leave those things alone.
