I promised in a post last month that I'd write some more about the PrimeGrid project, and it so happened this week that we made a discovery which gives me a good excuse to blog! On 31st October 2016 at 22:13:54 UTC a computer owned by Péter Szabolcs of Hungary reported via the BOINC distributed computing software that the number 10223*231172165+1 was prime.

CMCGS2015: Two days of Maths in Singapore

Last week I was lucky enough to spend a few days in the tropical city of Singapore, attending the Computational Mathematics, Computational Geometry & Statistics (CMCGS) 2015 conference. I was there to present a review paper on the achievements of the PrimeGrid project, which I have blogged and talked about before, but as a more mathematical rather than computationally-themed conference, it was also a good chance to make contact with researchers who might be less au fait with parallel computing than most.

As well as helping out with our drop-in workshop at the British Science Festival in early September, I also had the chance to give a talk as part of the Festival's public lecture programme. Over 75 people turned out early on Sunday morning to hear 'Seventeen or Bust: Solving hard mathematical problems with your help!', where I explained how the PrimeGrid project is working on a solution to Sierpinski's conjecture, a fifty-year-old unsolved problem in Number Theory, as well as finding record-sized prime numbers in the process.

As a follow-up to speaking at the British Science Festival in Sept 2013, I was asked to write an article for the Institute of Mathematics & its Applications about the PrimeGrid project. The full article is available online, or in the Dec 2013 edition of the Mathematics Today magazine.

As mentioned in Alistair Grant's blog about our exhibition at the British Science Festival, I also gave a talk as part of the BSF Maths programme entitled "PrimeGrid: Join in the search for a world record prime number".
