Prime Numbers Visualization. A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. Primes are special numbers, then what makes primality so special? Don Zagier, an eminent specialist, said: Upon looking at these numbers, one has the feeling of being in the presence of one of the inexplicable secrets of Creation. This image is created using circles with consecutive prime number diameters stacked on top of each other and repeated from a common origin. For each natural number n, we draw a periodic curve starting from the origin, intersecting the x-axis at n and its multiples. The prime numbers are those that have been intersected by only two curves: the prime number itself and one. The currently highlighted number show sum of divisors σ(n), and its aliquot sum s(n) = σ(n) - n, which indicate whether the number is prime, deficient, perfect or abundant.
