Ohio State University mathematician Niles Johnson got in touch on Friday to tell us that our π Approximation Challenge last year had inspired him to hatch an audacious plan to measure a really big π. The word ‘geometry’ is derived from the Greek for ‘measurement of land’, and Dr. Johnson took that quite literally: he wanted to measure the…
A man in London claims to have found a rat ‘the size of a small child’, near a children’s play area in Hackney, London. Alongside a photograph of gas engineer Tony Smith proudly displaying the gigantic creature held in the jaws of a litter picking stick, some news outlets have reported the claim that the rat was “about four foot long”.…
Restaurant chain Pizza Hut in the US have announced a promotion for “Pi Day” on March 14, involving an unlikely partnership with renowned group-theorist, Life-wrangler and apparent pizza-lover John Conway. (Apparently, pizza and pie are somehow linked in America. It is probably best not to worry about this.) Featuring on their blog as the inaugural post…

In fact, it’s so live it’s almost run its course: the third season will only be funded if at least $24,000 is pledged by Saturday 12th March 2016 at 4am…
Around about exactly this time a year ago, I bought the frivolous domain name three.onefouronefivenine.com, to celebrate π Day and to indulge my curiosity about a marvellous algorithm to compute π’s digits. This year, I’ve been thinking about prime numbers, and my hosting provider has run another sale on domain names. So, I’ve bought isthisprime.com. You…
Discrete Analysis, a new open-access journal for articles which are “analytical in flavour but that also have an impact on the study of discrete structures”, launched this week. What’s interesting about it is that it’s an arXiv overlay journal founded by, among others, Timothy Gowers.
Time for some more maths objects! This time I wanted to show you the various polyhedra I’ve got around my desk. The tetrahedron is made out of a paper plate, following the instructions on the brilliantly kooky wholemovement. The sonobe cube is a classic. Mine’s made out of Post-It notes. The swirly thing is made out…
