A Fractal Characteristic of the Distribution of Prime Numbers

Created by

A resource for realizing the fractal characteristic of the distribution of the set of Prime Numbers. The set of prime numbers undergoes 2-D maps from the number line to Quadrant I of the xy-plane. A Line-graph relation is generated through the mapped primes numbers. The fractal characteristic of the relation is developed and verified. Graphs of the patterns of the relation for increasingly larger subsets of the prime numbers are presented, visualizing the fractalness of the relation. The re

Experience

I began mathematics teaching as a college math/computer tutor in 1988. I started onsite high school mathematics teaching in 1996. I started online mathematics teaching in 2002. I am still currently teaching mathematics.

Teaching style

I patiently make mathematics understandable to any student, rewording concepts without losing any content for ease of reading. For handouts and study guides I use clear visual illustrations.
