James Maynard, one of the prize winners at the European Congress of Mathematics, is counting primes that don't have 7s in them. But why?
In this excellent talk the mathematician Vicky Neale gives a fascinating and easy-to-follow introduction to the prime numbers.
There's been progress on one of the biggest open problems in maths: the twin prime conjecture.
This year has seen a flurry of results as mathematicians hunt down the elusive proof of the twin prime conjecture. Will they get their wish for Christmas this year?
Agreeing to pay £50,000 for something worth £2 wouldn't win you any haggling competitions. In mathematics, however, a similar result can bring you international acclaim. This is the case with recent progress towards the famous twin prime conjecture.
We know there is infinitely many primes, but are there infinitely many twin primes?
