Everyone loves the internets.

• Greta Christina's Blog - Great blog with lots of cool thoughts and pictures. Recent case in point. Plus, she linked to me, so she obviously has good taste.
  
• Good Math Bad Math: Mathematical constructions - MarkCC discusses what axioms and definitions are. I sort of glossed over this in a previous post, but Mark actually knows what he's talking about whereas I don't.
• Infophilia: The Modus Tollens Exception - at some point I was planning on talking about when absence of evidence can be evidence of absence, but damn, Infophilia covered this several months ago, and I couldn't have said it better myself.
• a geocentric view: Turning a Sphere inside out - Topology video!
• Dresden Codak - Good news! Dresden Codak is now on a weekly update schedule. This webcomic brought us classics like this. "I have to find a way to get to school... WITH SCIENCE" I totally fantasize about saying something like that all the time.
