Caption

The Ulam spiral (or prime spiral) is a graphic representation of positive integers displayed in ascending order from the centre and spiralling out. As the size of the spiral increases, surprising patterns of primes appear forming diagonal lines, here represented with white numbers, where nonprimes are grey. The Ulam spiral is connected with a number of unsolved problems in number theory such as Goldbach's Conjecture and the twin prime conjecture. The spiral was first devised by the mathematician Stanislaw Ulam in 1963. Computer artwork.
