Bit-player will be hosting the 130th Carnival of Mathematics, the monthly celebration of math(s) writing on the Web organized by The Aperiodical. Submissions are open now through January 9.

Please contribute! Anything that might engage or delight the mathematical mind is welcome: theorems, problems, games and recreations, notes on math education. We’ll take pure and applied, discrete and continuous, geometrical and arithmetical, differential and integral, polynomial and exponential…. You get the idea. And don’t be shy about proposing your own work!
