# Carnival of mathematics

The 36th Carnival of Mathematics is now up at Rigorous Trivialities.

In my RSS newsreader, I have so many different math/theory blogs listed that I've had to group them into categories — the ones by algorithms researchers, the ones about visualization, the ones using category theory, the ones more about politics than mathematics... (and now that I write this down here, it's starting to sound like Borges' encyclopedia). Anyway, I have only a half dozen or so grouped under "mathematics is serious business" and rigtriv is one of them. He's worked hard to inject some serious research mathematics into a carnival that is often too heavy on the side of elementary material (much as I may like such material myself), and found some interesting posts to link to, so go read.
