Lasrick writes "I Love this article in Smithsonian by Richard Conniff. One of my geology professors was in grad school when the theories for plate tectonics, seafloor spreading, etc., were introduced; he remembered how most of his professors denounced them as ridiculous. The article chronicles the introduction of continental drift theory, starting a century ago with Alfred Wegener. From the article: 'It was a century ago this spring that a little-known German meteorologist named Alfred Wegener proposed that the continents had once been massed together in a single supercontinent and then gradually drifted apart. He was, of course, right. Continental drift and the more recent science of plate tectonics are now the bedrock of modern geology, helping to answer vital questions like where to find precious oil and mineral deposits, and how to keep San Francisco upright. But in Wegener’s day, geological thinking stood firmly on a solid earth where continents and oceans were permanent features.'"
