Is it possible that we "know" math already? You've all heard of Stan Lee, I presume? He's able to multiply, divide, add and subtract, cube, give the root, etc. of numbers within seconds and with calculator accuracy. I was watching a special on him recently. A brain scan revealed that Stan Lee's brain shows activity in a different area when doing math than a normal person's. Stan's math skills are based in the movement/muscle control area of the brain. So I thought about it. How much math does our brain do for even our simplest motions through our muscles? Vast amounts. You know how your limbs are oriented in space without looking at them, so the brain must calculate the angles of joints, perhaps based on the tensity of the attached muscles, just one example. Is it possible that our brain use functions such as those of trigonometry, perhaps even vectors and calculus already, subconsciously, as part of just performing tasks? Math is a way man describes the world and predicts things. I think that it's an even deeper part of us, and the math we are able to write down and number crunch is merely scratching the surface of what our brains truly do, mathematically. And, maybe those calculations we do on pen and paper is just what we are able to pull from our subconscious and think about. Your heart rate changes based on your fitness. A stronger heart can pump blood more effectively, resulting in a lowered resting heart rate. How does your brain know how to adjust the heart rate? You are able to exert the exact amount of effort required to bend your arm to a 90* angle. Does your brain already know that F = ma?
