Twelfth Linkfest
This past half week, I was in Chicago, first to give a speech at the grad student logic seminar at UIC, and then to attend the Reverse Mathematics Workshop at the University of Chicago. Both events were awesome, I got to meet and hang out with lots of great mathematicians. It was a half a week of constant math discussion. I learned quite a bit.
Meanwhile, the blogosphere continued to churn out tons of great scholarship, some of which I’ve picked to share with you. Hope you enjoy these links.
The previous linkfest was Linkfest 11.
