The other day I failed to help with homework. New ways to describe the same old stuff, and baffle the old! But here my math works, F-stops and ISO settings to capture an image. These fuzzy little spirals are nature's math. Precisely designed to best capture spheres floating in the air. Then to make chemical spirals to perpetuate the process. Nature did math long before we put two and two together for the first time. I start to have visions of numbers falling through air, combining to solve equations that would baffle Euclid and Einstein, much less Grandpa at the kitchen table. How's that for a rationalization of failure? Meanwhile, Canada rush keeps growing in wetlands in AL, AR, CT, DE, FL.
