Okay, I'm about a week late posting this--super sorry! The
second edition of
The Carnival of Mathematics is up at
Good Math Bad Math. First, Mark does a great job as host; I love it when the Carnival host works a story into the post.
Second, once again the quality of blogging is exceptional. My favorites (sorry, no hotlinks, you'll have to go over to
the Carnival itself for those) are the spider problem (fun puzzle), the rubiks cube (I'm meaning to write a post on group theory--and maybe even groupoids, ooh), Escher (Escher, 'nuff said), and the halting problem (Turing is
da Man!).
