The 30th edition of Tangled Bank, the carnival of science-oriented blog posts, is now up at The Geomblog. I didn’t submit anything, but Suresh has noticed that the squishy sciences tend to be over-represented in these carnivals, so he decided to take the initiative and include pointers to some interesting physics and math posts. So my entry on the arrow of time was included, as well as a nice older post by John Baez on topology and a newer one by Cosma Shalizi on Gödel’s theorem.
