"Arithmetic has a very great and elevating effect ..." – Plato

"Might poets and visual artists consider searching in the real world outside the range of ordinary dreams for unexplored dimensions, depth, and meaning?" – Edward O. Wilson, The Meaning of Human Existence

Gary William Croft



Gary Croft is a guerrilla arithmetician well-schooled in "shallow" mathematics. For a quarter century, Croft has pursued the secret of prime numbers as a visual artist seeking the beauty one would expect of a sequence deemed for two millennia to be fundamental, powerful and mysterious. Ignorance being the mother of necessity, his method–if you can call it that–has been to 'go native' and engage directly with numbers in a hermeneutic circle (or should we say spiral?). As he puts it, "Self-taught? No. Number-taught would be more accurate. Almost everything I know about numbers I learned from numbers."

Croft first made his Prime Spiral Sieve 'public' in July, 1993, when he presented it to City University math instructor Mark Wahl while attending his class titled "Mathematics: Its Meaning, Mystery and Methods" (July/August, 1993). Mr. Wahl, who authored A Mathematical Mystery Tour: Higher-Thinking Math Tasks was intrigued enough by Croft's 8-dimension / modulo 30 spiral sieve that accounted for all prime numbers greater than 5 that he made copies for his records. Almost a quarter century later, it turns out that the algorithm transcends its exceptional efficiency (in fact, the fastest of its kind), by serving as a deeply illuminating gateway to a beautiful and mysterious universe of number patterns and geometric symmetries that provide deep insight into the distribution of prime numbers, et alia.

Croft's Career Highlights::
– Sr. Director, Global Procurement & Business Operations, Microsoft Corporation (retired from Microsoft in 2005 after 10 years there)
– Director, Purchasing and Accounts Payable, University of Washington

Croft currently resides on beautiful Whidbey Island, appropriately in the little unincorporated town of Freeland (originally established as a commune), where he lives on a hill looking down on his soul place, Holmes Harbor.
