I’m going to abuse this here soapbox I have constructed to do a friend a favour. Here’s the friend, exhibiting typical behaviour:

I’ve mentioned my good friend David Cushing a few times here. I once even managed to record him doing a pretty clever card trick. He sits next to me in our office at Newcastle University’s School of Maths and Stats and when he isn’t doing card tricks he’s usually trying to grab my attention with unusual maths questions (or balloon polyhedra or potentially libellous “facts” about animals).

Reader, I have some good news: you too can share in the glory of David’s existence because he’s started a blog, called The Adventures of David Cushing. He’s already written about a few interesting mathematical factoids and has been asking me all week to post about it here. So please, have a look — you might even find it interesting!
