I was in the kitchen this morning making breakfast and accidentally knocked over some stuff on the floor (as I am prone to do). In jest, I turned my face toward the ceiling and shook my fist, "Curse you, Newton, and your theory of gravity!" To which my dad said, "It's not a theory, it's a law." I then explained, with good humor and reason, the scientific definitions of "theory" and "law," and how they differ from the common, everyday definitions. My dad's head spun a little. He's one of those who has always expounded the common Creationist misconception that evolution is "merely a theory, not a fact." He didn't comment on that, though. He merely said, "That's stupid."
But maybe, just maybe, he'll look at evolution a little differently now. I can dream, can't I?
