It looks as though the Carnival of Mathematics is dead. The Blog Carnival site says “It appears that this carnival is no longer accepting submissions.” I may have had the honor of hosting the last Carnival of Mathematics unless the carnival is resurrected.
By the way, I also wanted to mention the previous blog post on Let’s Play Math. Denise links to a TED presentation by Robert Lang on origami and math. She pulls out this quote from the talk:
The secret to productivity in so many fields … is letting dead people do your work for you. … take your problem and turn it into a problem that someone else has solved and use their solutions.
Update: According to Jason’s comment below, rumors of the death of Carnival of Mathematics have been greatly exaggerated.
