Who could have guessed that this non-story about somebody being out of his depth and quite obviously wrong would get so out of hand? Here’s an update on The Continuing Tale Of The Man Whose Claims Couldn’t Be Verified.

Riemann Hypothesis not proved

Here’s a tweet from Alex Bellos this morning:
BBC claims Nigerian solves Riemann Hypothesis, most famous problem in maths. Surely a hoax! https://t.co/Wkltfkh2P3 https://t.co/UHGy9W8shC

He’s right to be surprised – as reported in Vanguard, a Nigerian newspaper:
The 156-year old Riemann Hypothesis, one of the most important problems in Mathematics, has been successfully resolved by Nigeria Scholar, Dr. Opeyemi Enoch.
Suspicion levels are raised, as the paper also reports:
Three of the [Clay Millenium Prize] problems had been solved and the prizes given to the winners. This makes it the fourth to be solved of all the seven problems.
Unless we missed something, that’s not massively true – the only Millennium Prize problem solved so far is the Poincaré conjecture.
Make your own bauble with icosahedral symmetry with Shapeways
Internet 3D printing emporium Shapeways has released a nifty little tool to create your own unique Christmas bauble, which they’ll print out and send to you in time for the festive season.
It works by mapping a triangular design onto a blown-out icosahedron, and applying some “kaleidoscope effects”. As far as I can tell, that means they expand and rotate the patterns so they overlap.
There’s a selection of built-in patterns you can choose from, or you can upload your own pattern to make a really unique decoration. However, because the resulting object needs to exist in the real world, you need to take care to make sure it all comes out in one connected piece. Shapeways have written some very clear instructions about how to achieve that.

Cheng vs Colbert

Mathematical app roundup, October 2015

I notice that our post queue is filling up with interesting mathematical apps, so I thought I’d deal with them all in one big roundup post. Read on for a mix of mathematical games, apps to help with calculations, and some frankly awful art.
Review: Unique polyhedral dice from Maths Gear
Our good friends at Maths Gear have sent us a tube of “unique polyhedral dice” to review. The description on mathsgear.co.uk says they’re “made from polyhedra you don’t normally see in the dice world”. My first thought was that we should test they’re fair by getting David to throw them a few thousand times but — while David was up for it — I’d have to keep score, which didn’t sound fun.
So instead we thought of some criteria we can judge the dice on, and sat down with a teeny tiny video camera. Here’s our review:
