The Ordered Distribution of Natural Numbers On the Square Root Spiral

Harry K. Hahn

Abstract

Natural numbers divisible by the same prime factor lie on defined spiral graphs which are running through the “Square Root Spiral“ ( or “Spiral of Theodorus” or “Wurzel Spirale“ oder “Einstein-Spiral” ). Prime Numbers also clearly accumulate on such spiral graphs. And the square numbers 4, 9, 16, 25, 36 … form a highly three-symmetrical system of 3 spiral-graphs, which divide the square-root-spiral into 3 equal areas. A mathematical analysis shows, that these spiral graphs are defined by quadratic polynomials. The Square Root Spiral is a geometrical structure which is based on the 3 basic constants 1, sqrt2 and Pi , and the continuous application of the Pythagorean Theorem of the right angled triangle. Fibonacci number sequences also play a part in the structure of the Square Root Spiral. Fibonacci-Numbers divide the Square Root Spiral into areas and angle sectors with constant proportions. These proportions are linked to the “golden mean” ( golden section ), which behaves as a self avoiding walk constant in the lattice-like structure of the square root spiral.  see FIG. 1 / 9 / 10 / 18 / 19
