John Baez, the very first maths blogger, has started a new blog called Visual Insight. It’s hosted by the American Mathematical Society and is “a place to share striking images that help explain advanced topics in mathematics.”
So that’ll be nice.

Translate Numberphile, please / Traduisez Numberphile, s’il-vous-plaît / Bitte übersetzen Numberphile…
Numberphile is that cool YouTube channel with the videos about the numbers and the philes. You might remember them from the time they did that ace video about our integer sequence reviews. But if you’re unlucky enough not to understand the English as she is spoke, then that’s no use to you.
But it could be! Chief Numberphile Brady Haran has set up a page asking for translations of the videos, so everyone can enjoy them. As long as you’re fluent in one of the languages for which a video already has subtitles, the process is pretty simple: you download a caption file in one language, translate it into another, and upload it back to the site. And then you’ve done a good deed!
Brady’s just posted on Twitter that he’s already approved 24 translations since starting the project yesterday evening, so join your fellow Frenchmen/Flemings/Faroese and get translating. (I suggest you start with “Six Sequences”…)

Deligne Day: October 5, 2013
A bit of press release copy-pasting for you now, as the Simons Foundation announced a celebration of the mathematics of Pierre Deligne. When the release first went out it was called ‘Deligne Day’, but cooler heads have prevailed and it’s now “A Celebration of the Mathematics of Pierre Deligne”. It’s also my dad’s birthday, as it happens.
Maths Careers Poster Competition 2013/14
The IMA Maths Careers website has launched its annual poster competition. This time in collaboration with the British Museum’s Citi Money Gallery and part of the Mathematics of Planet Earth, the competition asks entrants to design a single global currency:
Imagine there was a single global currency; what would it look like? How big would it be? What would it be worth?
Your poster should be a pitch to the ‘Bank of the planet Earth’, outlining why your design should be commissioned for minting. The poster must include:
The poster should be no larger than A4. Colour may be used in coin designs for effect. There are three age categories: 11-13, 14-16 and 17-19. One entry per person per category only is allowed.
The main prize in each age group is an Android tablet and family tickets to the latest exhibition at the British Museum. The deadline for entries is midnight on 15th January, 2014.
Full rules and to submit entries: Poster Competition 2013 / 2014 at Maths Careers.
Computational mathematics in the cloud with Sagemath
Sage is a free, open-source computational mathematics system in the vein of things like Mathematica and Maple. For the past few years, there’s been an online version called the Sage Notebook which worked pretty well, but it was pretty slow and not particularly easy to use.
Now the creator of Sage, William Stein, has started work on The Sagemath Cloud. It’s considerably more ambitious than Sage notebook – as well as the Sage notebook interface, it gives you a sophisticated area where you can write LaTeX files with live preview, work on IPython notebooks, and even bring up a Unix terminal to do the kinds of things you need a Unix terminal for.
Yoshimoto Friends
Here’s a happy little film starring two Yoshimoto cubes, by Justin Lanier and Paul Salomon of Math Munch. Enjoy!

Hyperbolic Hyperbolic Hyperbolic: Daina Taimina at the DUMBO Arts Festival 2013
Fans of hyperbolic crochet, and hyperbole, will be pleased to hear that Daina Taimina’s exhibit ‘Hyperbolic Hyperbolic Hyperbolic‘ is being shown at the DUMBO Arts Festival in New York, on 28 & 29 September. The show features examples of hyperbolic crochet, and invites visitors to experiment with their own hyperbolic crochet and paper creations.
