The human mind is itself a miraculous machine. I am writing right now, but I have no idea how this is happening. I know that my brain is composed of a cerebrum, a cerebellum, and a medulla oblongata, but these are just words. I know that electrical impulses are involved somehow, but that is about the extent of my understanding of the mechanics. And while I at least have an intuition as to how an airplane works, I really have none with respect to my brain. Frankly, lots of what appears on my computer screen is as much a surprise to me as it is to you. I certainly never expected over my oatmeal and English muffin this morning to be writing about Bernoulli's principle today. For that matter, I have no idea why I like English muffins. But I do.
