For various reasons I have recently been reading a bunch of books broadly addressing the theme “what is mathematics?” (Linderholm was accidentally a lead-in, and clearly belongs in the category.) This one is a short (under 100 pages) and snappy read, … Continue reading
I have seen attributed to Halmos (Linderholm’s advisor) the description of this book as an in-joke to the mathematical community, and that’s about right: I don’t think it would be possible to explain why it’s funny to someone who doesn’t … Continue reading
I like to study reflection groups of various kinds. Let Sn denote the group of permutations of n points, let GL(n, q) denote the general linear group of invertible linear transformations of an n-dimensional vector space over the finite field with … Continue reading

Had a great time at March for Science MN last weekend. (The fact that it was in the 70s and sunny didn’t hurt!) Here are some photos. Some more posters I liked but didn’t get good photos of included … Continue reading
Purely in the category of self-congratulation: I received a lovely note (edited below) from an advisor in the University Honors Program, for which I’ve been teaching multivariable calculus, differential equations and linear algebra this year. I heard through many disappointed … Continue reading
Until a colleague told me about it, I had not known that there is a Gauss family connection to Minnesota: Carl Friedrich’s second son (first by his second wife) Eugene had a falling out with his father, came to America, … Continue reading
As I mentioned, after Vancouver I went to a conference at Herstmonceux Castle in Sussex, England. It was mathematically excellent, and I feel that BBC detective shows properly prepared me for my first visit to the UK. Trees in England … Continue reading
