"Pendulum Swing"

With all the crazy conversations that go on, it is very refreshing to have a true scientific conversation with a student. A fourth grader was in the mood to talk and wanted to discuss space. We talked of stars, planets, galaxies, the speed of light and the possibility of space exploration and colonization. We talked of the unfathomable wonders of the universe. Also mentioned was since the morning was so foggy it reminded him of the zombie apocalypse and he needed to practice patting his head and rubbing his belly. Apparently this will protect you from a zombie attack, just one of the interesting facts of the universe.
