Carnival of Mathematics #18

The 18th Carnival of Mathematics is up at JD2718. Outstanding work by Jonathan in assembling a nice variety of posts (52 topics by 49 different authors). Good thing I have no school on Monday, so I’ll have time to play with some of the questions to which Jonathan has linked (I don’t think I should bring them to the Homecoming Dance tonight). Anyway, have fun at the Carnival!
