For writing practice, Samuel Hansen and I are collaborating on a new blog, Second-Rate Minds. We take the name from a quote from the beginning of A Mathematician’s Apology by G.H. Hardy (1940):
There is no scorn more profound, or on the whole more justifiable, than that of the men who make for the men who explain. Exposition, criticism, appreciation, is work for second-rate minds.
We plan to alternately write short pieces on and around mathematics and edit each others writing. I wrote the first post, “Moving on a strange diagonal“, a write-up of my 2010 Maths Jam Conference talk about a puzzle and my thoughts on its use in education. Expect future posts at roughly two a month. If you want to keep up with future posts there is an RSS feed and a Twitter account.
