Information theory is, in my opinion, basically the study of Euclidean spaces with a huge dimensionality, particularly problems like sphere covering and sphere packing. Many things are easier when the dimensionality approaches infinity, but unfortunately such a space is quite hard to visualize and usually impossible to deal with directly using a computer (how would you calculate the Voronoi regions of 2^1000 points?), so it can be intimidatingly abstract and theoretical at first. However, once one learns to visualize such spaces, the theory becomes quite delightful to study.

I'm having some difficulty accessing many U.S. sites (MSN in particular) these days, because the Taiwan earthquake broke many fiber-optic cables. Don't feel surprised if there is no update for one week or more.
