I tried to imagine how many trees are in the Nantahala National Forest where I live, and I could not think of a number large enough to express that idea. I breathed in our air here today while exercising and was so invigorated by it. We are surrounded by almost pure oxygen here, it is so wonderful. Just to try to imagine that mathematical figure and even remotely do so was an accomplishment for me. I am not at all mathematically inclined, so this was HUGE for me in some strange kind of way.
