Over at Abstract Nonsense, they're hosting a great blog carnival (a what?).

It's called the Carnival of Mathematics, and the first post is now up! Heath Raftery's probability paradox post is already generating the most talk. Although the scale is different, the ensuing discussion already reminds of the discussions over the Monty Hall dilemma.

Of special interest to Grey Matters readers would be Barry Leiba's Number Tricks post. Before you read it, though, check out this site (Flash required) so you can be amazed and understand what Barry is talking about.

Enjoy this one, and look for the next one on February 23rd over at Good Math/Bad Math!
