Tends (The Ulam Spiral) 



The Ulam Spiral was first found by the mathematician Stanislaw Ulam during a scientific meeting in 1963. Ulam was doodling on a scratch


of paper, starting with the number 1 in the middle and spiralling all the numbers out. When circling the prime numbers he found that 

these tend to line up in diagonals.
