MathsJam this month fell on the day before my birthday, which meant not only was our ‘Jam well supplied with birthday cake, but there was a jubilant mood only aided by the presence of some puzzles I’d written for my birthday party. Everyone had a good crack at the maths-related one, and found it entertaining (see: future Puzzlebombs, where said puzzles will almost certainly feature).

Happy Birthday Euler!
Today is Euler’s $-306 \times e^{i \pi}$th birthday, and Google have chosen to celebrate (despite ignoring several other prominent mathematical birthdays, including Erdős’s centenary – see the @MathsHistory twitter feed for a full list) by creating a Google doodle on their homepage.
For anyone who isn’t aware, this is when Google changes the image above the search box on the homepage at Google.com, so it still says ‘Google’ but using an appropriate image, which sometimes has built-in interactive elements. I thought it was worth pointing out some of the fantastic maths they’ve included in today’s doodle.
The Number Project, by Brandon Wilson
Brandon Wilson is drawing a logo for a number each day this year. He started at 0 on the first of January, and he’ll finish with 365 on the first of January 2014 (or with 364 on the 31st of December. Not sure.) Sadly that means 367 – the largest number whose square’s digits form a strictly increasing sequence – misses out on a logo, but if your favourite number is a natural number at least a couple of units smaller than that, you’re in luck.
Brandon’s blog is NSFS — Not Safe For Synaesthetes — since numbers may appear different to how you imagine them.
