ABSTRACT
It was some time ago now when my son came home from school and reported around the dinner table that he had learned something new, something that was neat. The moon did not shine by its own light. Instead, it reflected the light of the sun. “Ah,” I sighed to myself, “it has started already.” You see, I knew he didn’t really understand it. It was just an isolated fact. Something he had been given and made to feel proud about having. That’s why, after we had talked about things for a while, I asked him: “But, Pete, if that’s so, how can we see the moon at night, when the sun isn’t even there?”
