A while ago I collected a few of the mathsy games I play on my phone to while away my commute. I’ve found a few new ones since then, so I thought I’d do a new post to tell you about them.

### Integer sequence review: A225143

*The Online Encyclopedia of Integer Sequences contains over 200,000 sequences. It contains classics, curios, thousands of derivatives entered purely for completeness’s sake, short sequences whose completion would be a huge mathematical achievement, and some entries which are just downright silly.*

*For a lark, David and I have decided to review some of the Encyclopedia’s sequences. We’ll be rating sequences on four axes: Novelty, Aesthetics, Explicability and Completeness.*

A225143Primes from merging of 10 successive digits in decimal expansion of $\zeta(2)$ or $\frac{\pi^2}{6}$.

### Matt Parker: Number Ninja

Behold! Further evidence that maths is a thing which popular entertainment can be based on, and not the terrifying subject of horror and difficulty that its stereotype would suggest. Not only do we have a maths-based TV gameshow (now in its second series), and even a maths-based cop drama, but maths is also the topic of a UK-touring comedy show, performed by Aperiodical homie Matt Parker.

We sent Dave Hughes, of the Leeds MathsJam, along as a scout to one of Matt’s recent performances, and here’s what he thought of the show.

If you never thought maths could be made funny, you’ve never seen any of Matt Parker’s shows. Matt’s latest

Number Ninjashow takes a whirlwind trip through the everyday uses of mathematics in an accessible and fun way. His friendly and approachable personality invites audience participation pretty much all the way through with demonstrations of concepts which may have been previously shrouded in mystery.This show debunks a number of mathematical myths and shows the audience that maths is not to be feared. You will go away from this show with much to think and talk about. Just how much of everyday life is really down to coincidence? Ever wondered how barcodes work? Who did knit that scarf for Matt? All these questions and more are answered here – it’s designed to be appealing to all – you don’t have to be a complete number-brain to enjoy it!

There are still a couple of dates left on the tour, in Havant (Hampshire) and Barnstaple (Devon). For more details, visit www.standupmaths.com. If you can’t catch him on this run, Matt also does regular shows in London and occasionally tours as part of the excellent Festival of the Spoken Nerd.
