Maths legend Colin Wright posed this question on Twitter:
It led to a flurry of interesting replies, and here’s some of them.
After all the excitement of the UK Rubik’s cube championships last weekend, the European Court of Justice ruled on Thursday that after 10-year legal battle, the trademark on the shape of the Rubik’s cube is not valid.
The trademark was registered in 1999, but since the original design of the cube was never patented, it’s long been on shaky ground. The court has ruled that the shape of the cube alone is not enough to protect it from copying, and that a patent would be needed to do so. The implications are that licensed manufacturers of the game could now face more competition from cheaper overseas sellers.

As part of our special Apéry takeover today, I chatted to mathematicians Ben Sparks and James Grime, to find out what we know about the mathematics Apéry did – it’s an enjoyable 10-minute listen.

Christian’s put together this fun applet for exploring the Zeta function – you can move your pointer around to reveal the value of $\zeta$ at each point in the complex plane.
The hue (colour) revealed is the argument of the value, and the lightness (bright to dark) represents the magnitude. There’s a blog post over at Gandhi Viswanathan’s Blog explaining how it works.
The resulting plot has contour lines showing how the function behaves.
Here’s a round-up of some of the news from this month.
Never-ending Turing centenary, part XLVI
The Alan Turing centenary shows no signs of abating.
First of all, there’s a marvellous new art installation under Paddington Bridge in London, in memory of Turing. There’s also a theatre piece called Breaking the Code, showing at Manchester’s Royal Exchange Theatre until 19th November.
Secondly, work continues to introduce legislation in the UK pardoning all gay men who were convicted of crimes related to homosexuality, in the same way Alan was a few years ago. Ministers said they were ‘committed’ to getting the law passed, but in an emotional session the bill was “talked out” by minister Sam Gyimah, meaning it wasn’t voted on.
LMS wins the first Royal Society Athena prize
The London Mathematical Society (LMS) has been honoured this autumn by receiving the first Royal Society Athena Prize to recognise its advancement of diversity in science, technology, engineering and mathematics (STEM) within the mathematical community. The prize was awarded in a ceremony at the Royal Society’s annual diversity conference on 31 October.

Spanish independent publisher Kronecker Wallis is making a new edition of Isaac Newton’s Principia Mathematicia, using a Kickstarter campaign to fund the initial print run. Here’s their video:
It looks like it’ll be a fairly pretty object, and they’ve put a lot of time and thought into choosing the paper, fonts and layout. Their Kickstarter runs for around another 24 hours, and a pledge of €45 or more will secure you a copy of the finished article.
