Beauty and the Maths • mathmajik: The Prime Number Spiral was allegedly discovered by physicist Stanislaw Ulam while doodling during a boring physics talk.  When the natural numbers are arranged in a spiral on a grid, and the prime numbers are highlighted, an interesting pattern emerges: diagonal lines appear. The effect seems sufficiently obvious to preclude any sort of optical illusion, but thus far there is no explanation for the effect

Stanislaw Ulam's Prime Number Spiral, discovered while doodling during a boring physics talk.

The Ulam spiral is a simple method of visualizing the prime numbers that reveals the apparent tendency of certain quadratic polynomials to generate unusually large numbers of primes.

Found this Braille style picture of the Ulam Spiral: “ When arranging the natural numbers in a spiral and emphasizing the prime numbers, an intriguing and not fully explained pattern is observed,.

External Pulsed Plasma Propulsion (EPPP)  is something that’s been discussed for some time. In fact, it was originally proposed by Stanislaw Ulam way back in 1947. Unfortunately the public perception of atomic technology as well as pieces of otherwise well meaning legislation have called into question the feasibility of spacecraft that operate using this advanced principle.
