Ulam spiral

You will not believe at first glance that it is generated using prime numbers. In order to generate it, the numbers are arranged in a spiral, as follows: Then the prime numbers are marked. Note the abundance of diagonals. In the applet above you can see the spiral made up to 1014. Move the graph by clicking in the arrows or using the arrow keys. You can also see the position (x, y) in the spiral and the number n of any point of the graph by moving the cursor to that point. Move the center by typing a new number (up to 14 digits) in the left input box and press the return key. Change the starting number in the center of the spiral by typing a new number (up to 14 digits) in the right input box and press the return key.

The formula that gives the numbers in the diagonal lines can be expressed using quadratic polynomials. When the quadratic polynomial cannot be factorized, then its diagonal will contain primes.

That is all I require: Building Numbers

Summary: Visualizations of Ulam Spirals. Recently a brief discussion evolved into an hour of visualizations of the compositeness of numbers. A number that is the power of a prime seems to be closer to a prime than a number that has lots of prime factors. ω(n) is the number of distinct prime factors of n, a notion which is used here and there. How to visualize the compositeness of a number? We tried a few approaches, some of which we'll show in future posts. Each cell is colored based on its omega. A variation, this time showing the structure of each number: Each number is represented by a square that depicts the number's prime factorization. Color is given by the size (so to speak) of the largest prime in the factorization.

But we didn't like those as much. Here are some closer views of the 2D representations. If there's any interest, we can make our PDF versions available. A wall-sized print would be interesting.

Is there any pattern? Several Pratt students study a 48" x 96" print of one prime number study. Developing a Color System Looking at a matrix of integers in which the prime numbers are highlighted, the gap in between any two primes forms a block of space. As the intervals get larger, the hue of the color transitions from blue to purple to red to green. Prime Factorization Graph. Prime number. Prime Sieve.

Primal Chaos

In order to have twin primes we cannot have any circle intersecting adjacently to 6k (obviously). Let's see how this happens: Please note that the reason I'm only using prime numbers for this is because we only need prime numbers. For example, the 9 is not needed because it is a multiple of 3 (3 is prime and can only fall on 6k). Same with 15, 21, 27 and so on (which are also multiples of 3). -Multiples of 3 can only fall on 6k. -Multiples of 5 can fall on 6k, 6k-2, 6k-3.
