Like many scientists, the wonder of the natural laws of the Universe is where I draw my spiritual inspiration. I also study the religions of the world, and have been fascinated by the reoccurring theme of Creation, Preservation, and Destruction. The Mandelbrot Set (top) represents Creation, with the emergent properties of a simple equation that produces such a rich, complex, and unpredictable fractal pattern that goes on into Infinity. The equation for hydrostatic equilibrium (bottom left) represents Preservation, describing the precarious balance between crushing gravity and expanding pressure inside of stars (including our own) to keep them in a stable, sustainable size for billions of years. The equation describing entropy (bottom right) symbolizes Destruction, simply stating that this fundamental break down of systems and accumulation of disorder either increases or stays the same over time, but never decreases. All three circle around the Delta, the symbol for Change.
