Matt Baker (who teaches the course) was my first math professor in college years ago. In fact, my first class on my first day as a freshman at Georgia Tech was his class. It contributed to my becoming a mathematician (and even a number theorist, although not the same field of number theory). In that, I'm happy. But I wonder whether or not his charisma carries through whatever formats in which he interacts with the students. It seems like some of that would be lost. I've never seen a professor teach both in person and through some sort of distance learning before.
