Happy 200th birthday, Mr. Charles Darwin.
There's a bulletin board at school dedicated to Darwin, with a couple big sheets of poster-board sized paper, for comments and/or debate. I swung by earlier in the day, and was a little upset that it had been taken down (the display had been up since last year.) "Well, that doesn't make sense," I thought. Why would they take it down on the 12th? (it could've been taken down yesterday, I don't have classes on Wednesdays.) Anyway, I walked by later to find a brand new display (where I got the above pic), and some brand new comment paper. Woohoo!
Other than the bulletin board, I don't think the school did anything for today. OSU had a banquet of some sort, but I live two hours away from Columbus. Were there any events going on in your area?
