CP and Cushing take the National Numeracy Challenge
Cushing was injured in a serious maths accident recently (he fell out of the bath) so I wanted to assess the damage to his number-wrangling faculties.

Fortunately, there’s the National Numeracy Challenge, which begins with a test to pinpoint your weak areas. National Numeracy is a charity that wants every adult in the UK to “reach a level of numeracy skills that allow them to meet their full potential.” Well, if there’s one thing we’ve got, it’s bags of potential.

Mathematical soap bubbles by Juan Bragado
I recently tried to blow some clever soap bubbles to demonstrate some maths concepts to some students. It went terribly. Juan Bragado is much better at blowing mathematical bubbles, so he’s made this gentle video showing all sorts of soapy polyhedra, and other mathematical shapes made from bubbles.

Oh, Stephen
“It is hugely complicated. In fact, compared to football I think Quantum Physics is relatively straightforward.”
– Professor Stephen Hawking
Even you, Stephen?
If you pick up basically any newspaper in Ireland or the UK today, you’ll probably find a story about Professor Stephen Hawking’s “formula for World Cup success”. At first glance, it doesn’t look good: The World’s Most Famous Scientist appears finally to have succumbed to the temptation of nonsense formula publicity.
Vi Hart has 3D printed a hypercube made of monkeys that has the symmetries of the Quaternion group
Group theorists, often interested principally in the abstract, have been known to neglect the vital importance of producing funky gizmos that exhibit the symmetries they have theorized about. Internet maths celeb Vi Hart, working with mathematician Henry Segerman, has addressed this absence in the case of $Q_8$, the quaternion group. The object they’ve designed is four-dimensional and made of monkeys, and they’ve done the closest thing possible to making one, which is to 3D-print an embedding of it into our three-dimensional universe, also made of monkeys. Their ArXiv preprint (pdf) is well worth a read, and when you get to the photos of the resulting sculpture (entitled “More fun than a hypercube of monkeys”), you’ll fall off your chair.

Aperiodical Round Up 10: a rathole down which valuable mathematical effort is being poured
Ten! TEN! TEN! Incredible. David Cushing asked me a very good question once: what have you done between five and ten times (inclusive)? Well, this is the last time ‘Writing an Aperiodical Round Up’ will be in the same category as ‘getting a new wallet’ and ‘saying hello to Peter Beardsley’.
Hello, my name’s Christian Perfect and, more often than an unbiased observer would expect, I find odd maths things on the internet.
Google Doodle: The Witch of Agnesi
Today’s Google doodle (for those not in the know, the Google homepage alters its header based on the date, and on dates of special nerdy significance, they theme them around relevant birthdays/anniversaries) is about Maria Gaetana Agnesi, a female mathematician. Agnesi was born on 16th May 1718, making today her 296th birthday. This means you have four years to prepare for her 300th birthday bash, which I hear is going to go off big style.
