My high school biology teacher was a scary jerk--at least that was his classroom persona, and it probably served him well in riding herd on bored 15-year-olds in a lab class. But intimidating asshole though he was, he didn't scare me away from being interested in the life sciences. I wish he'd taught us a bit more about how to take lab notes neatly, but we can't have everything.
P.Z. Meyers is like the cool, funny biology teacher I never had in high school (he teaches college biology, but that's a subnit, as my father would say). If you like learning new things, or thinking for yourself, or otherwise giving your brain a wee workout -- or if you just have a crush on cuttlefish -- you'll like his blog. I loved last Friday's photo of the Japanese Pancake Devilfish.
