Ulam Spiral Jigsaw Puzzle
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!

I had fun putting the pieces of the puzzles together. They weren’t to hard and the art was pretty. The colours and the images were pretty and vibrant.

Bought this as a Christmas gift for my sister and niece who love puzzles. Very cute. Good quality printing, even with the details of the leaves in the background.
