US organisations the Mathematical Sciences Research Institute (MSRI) and the Children’s Book Council (CBC) have founded a youth book prize, called *Mathical: Books for Kids from Tots to Teens**.* The prizes, awarded for the first time this year, recognise the most inspiring maths-related fiction and nonfiction books aimed at young people. This year, they’ve awarded a set of prizes for books released in 2014, as well as honouring books published been 2009 and 2014, plus two ‘hall of fame’ winners from the further past.

### Pi Day 2015: The Aperiodical goes π mad

Happy π day everyone! I hope you’re having a great day, and having lots of fun mathematical parties.

You may have noticed that here at The Aperiodical, we’ve been posting exciting π-related items all week – and here’s a list of them all, collected into one handy place. Enjoy!

### π and constrained writing

It’s a tool; a ratio, providing us simple rules for doing circular estimates. Admired regularly – and we all remember that today’s pi! Hooray! Let’s eat pie.

You may have noticed that the first paragraph of this article was immensely poorly written, and didn’t sound like good writing at all. And you’d be right – except writing it wasn’t easy as you’d think. I’ve written it under a constraint – that is, I’ve picked an arbitrary rule to follow, and have had to choose my words carefully in order to do so.
