Moving to Ithaca tomorrow (more or less). Time in the Twin Cities has flown past. Back to the monastic mathematical lifestyle!
Besides wrestling with Sage code and thinking a bit about polytopes and reconnecting with family and old friends, I spent some time learning about R, the statistics software I mentioned in an earlier course. I decided to take the quick introduction to R offered by Coursera, one of the major new forces in the MOOC movement. It is a nice way to structure my learning as well as learn about a potentially major competitor in the higher education landscape in coming years. Among other things, it's interesting to see how other professors teach: this is not something I experience much these days!
If/when I learn very cool new things from R, I will put some of them up here. For now, I have learned a very tiny amount about the growth of guinea pig teeth as related to vitamin C consumption, from a data set included with the standard distribution of R.
