We felt the waves of vibration coming from the tug boat today. The vessel was just running its generator, but waves, as my physics professor lectured so many years ago, travel. As college students we watched the diagrams and yawned through the films in physics. We dutifully memorized the necessary “laws” and promptly forgot them. But today we weren’t even all that close to the tug boat, and the vibrations carried through the iron hull, across the water, into our own hull, and right through the seats of our trousers.
There is, of course, significantly more theory to waves traveling than we felt in our trousers. A good teacher, and we have many in Rockland, will make that point, and will connect it to those vibrations. But we will remember them, we will remember wave theory, because of what we felt out on Rockland Harbor.
