Carnival of maths

Plus is proud to host the 68th edition of the carnival of mathematics, celebrating mathematical blogging!

The carnival invites mathematical bloggers to submit the recent blog posts they're most proud of and the current host then publishes a list of the best ones on the first Friday of the month. (You can find out more at Walking randomly.) So here we go....
