Welcome to #104 of the Math Teachers At Play (MTaP) blog carnival. A blog carnival is a regular blogging round up coordinated by someone (in this case Denise Gaskins) that moves around different blogs each edition. This time, I’m taking a turn.

### Katie’s Binary Nails Tutorial – and a puzzle

I’ve just posted my latest YouTube video, in which I explain how to use binary numbers to jazz up your nail varnish:

Alongside this video, I also have an associated puzzle for you to think about.

### Video: Mathematical Christmas Present Wrapping

If you were wondering what happened with all the left-over wrapping paper from this morning’s post about wallpaper groups, Katie has made a YouTube video demonstrating some mathematical quirks of gift wrapping. Enjoy!

### Naked Scientists on the Clay Millennium Prize Problems, f. Katie Steckles

The Naked Scientists Podcast has released an episode on the Clay Millennium Prize Problems, titled ‘The Seven Million Dollar Maths Mystery’. The episode description is:

This week, we’re investigating the Millennium Prize Problems – a set of mathematical equations that, if solved, will not only nab the lucky winner a million, but also revolutionise the world. Plus, the headlines from the world of science and technology, including why screams are so alarming, how fat fish help the human fight against flab, and what’s the future of money?

Better yet, the episode includes a contribution from our very own Katie Steckles talking topology, Poincaré and Perelman.

The episode is available to listen or download as a podcast or, less conveniently, at 5am tomorrow on Radio 5 Live (or later on iPlayer). Not a listener? Read a transcript.

### Katie Steckles is Greenwich University ‘Mathematician in Residence’

Our very own Katie Steckles is currently residing mathematically in the University of Greenwich’s Stephen Lawrence Gallery. She’s there until Tuesday the 26th, doing a variety of numerical, geometrical and otherwisely logical things for anyone who pops along.

### Video: The Aperiodical’s π approximation challenge

As part of our massive π day celebrations, The Aperiodical has challenged me with the task of assembling a group of mathematicians, some bits of cardboard and string, and a video camera, and attempting to determine the exact value of π, for your entertainment.

The challenge, which was to be completed without a calculator, involved using known mathematical formulae for π and its occurrence in the equations of certain physical systems. In the video below, seven different methods are used – some more effective than others…

If you reckon you too can ineptly compute a value in the region of π (in particular, if you can get a more accurate approximation than the date of π day itself, which gives 3.1415), feel free to join in the challenge and see how close you get.

### Maths at the British Science Festival 2014

Since the British Science Festival’s programme of events for the 2014 festival is now online, you can search through it to find all the mathematical/maths-related events which will be taking place this September in Birmingham. But this is a full-service maths blog, and so you don’t have to because **we’ve done it for you**. (If you’d rather take a look yourself, the full listing is on the BSA website).
