It looks like Number Gossip is back, as gossipy and numerate as ever. Tanya hasn’t announced anything on her blog yet, so I thought a quick public-service note was in order.

A new episode of the Math/Maths Podcast has been released.
A conversation about mathematics between the UK and USA from Pulse-Project.org. This week Samuel and Peter spoke about: Making Heisenberg more Certain; Matt Parker’s domino computer challenge; Turing Machine on a Penrose tiling automata; Bletchley Park Bombe hut restoration; Turing Monopoly; Measuring Women’s Progress in Mathematics; Mochizuki on ABC; Google Earth Fractals; and more.

Leaves are falling, a chilly wind is blowing and I can hear the distant thunder of undergrads’ hooves as they stampede towards my department. Yes, Summer is giving way to Autumn, so it’s time for another Aperiodcast. If you had “42 days” in the “when will the next Aperiodcast appear” sweepstake, report to the comments section below for your prize.
In this episode Peter and Christian were enjoying the comforts of their respective homes, while Katie was preparing to be sawn in half by a crazed Matt Parker at the British Science Festival. We talked about:
As always, we’re keen to hear about your mathematical exploits at root@aperiodical.com, and you still have eight days to submit items for the 90th Carnival of Mathematics, which you can do through our form.

Following on from our maths/knitting post earlier this month, we’ve found a knitting blog full of knitted MC Escher designs. The famously mathematical graphic artist MC Escher was king of tessellating designs with repeated fish, birds and other animals.
Jana, who writes the blog in question, has taken on the formidable challenge of writing knitting patterns for a variety of different Escher designs and not without a deal of success. The designs are all hand-knitted and are ridiculously intricate: while some are made from separate shapes stitched together, there are some which are knit in rows with two colours, using a pattern of her own design. Much maths and knitting respect is due.
All posts on her site tagged with ‘Escher’ can be found here; particularly noteworthy are a blanket with a fish design, and some beautiful cushions.

Friend-in-good-standing of The Aperiodical, Matt Parker, has something big planned for Manchester Science Festival and he needs your help.
Matt is trying to build a computer out of dominoes.
GeoGebra is a surprisingly capable piece of free dynamic maths software, used widely by teachers and geometry aficionados. We haven’t discussed it here before, but people have created some really nice interactive tools with it, so we might do a round-up in the near future.
Earlier in the year, the developers released an HTML5 version of GeoGebra, dropping the dependency on Java, which means it works on new-fangled devices such as the iPad through the web browser. Now, following queries about a GeoGebra iPad App from “many people”, a Kickstarter project is trying to raise funds to develop a native iPad App, to be available for free from the Apple App Store.
They don’t say how the iPad app will be different to the HTML5 one, but I assume it’ll make use of the native controls and widgets to present a smoother interface. They could probably do with providing a bit more information to encourage interested parties to cough up the $10,000 they’re asking for. Right now they’re at just over $2,500.
Fellow Androidists can be reassured: the FAQ says that they are planning on getting round to “other platforms” once the iPad version is done.
