Some things are easy to learn, and other things are far more challenging and difficult. Learning to count, for example, is fairly simple. On the other hand, we would find the science and math needed to send a rocket into outer space, to be complicated. It takes years of painstak- ing study to learn that kind of math, and its application to rocket science. But we expect that to be the case. We’re not surprised, because we have a sense of the technical difficulties involved. In fact, if you reduced it to simple math, you would find it dangerous.
