Prime numbers are a fascinating part of the Universe. The are numbers divisible by the number 1 and the number itself. One of the mystical searches regarding to these numbers is when and where they occur. Periodically one used to see a reference to someone who has discovered one more prime number using a pencil and paper. Today they are found with the use of Matrix-like electronic black boxes called algorithms which search on their own and notify the world when it had found another.
On a similar tack recently while surfing the Internet I stumbled across a demonstration of prime numbers called Ulams Spiral. You-lam or oo-lam... the correct pronunciation I know not. But contnuing on...
The prime spiral, also known as Ulam's spiral, is a plot in which the positive integers are arranged in a spiral, with primes indicated in some way along the spiral. There was an accompanying plot of the spiral but it wouldn't copy into the blog. But it should brighten anyone's day just to know there is a thing called Ulams Spiral out there.
Or not.
Ulams Spiral is proof that were all on this flight together.
