Ulam Spiral Silver Plated Necklace
- from our Affiliates
If you plot every integer in a spiral and darken the prime numbers, something weird happens. A pattern emerges. There's no known way to predict where prime numbers will occur, but the beautiful spiral patterns they create taunt mathematicians with the possibility that there IS a way. Ulam, the mathematician who discovered this effect, did so while doodling on a napkin during a boring conference talk!
