One of the many things I enjoy about teaching my university class, Science, Feuds, Scandals and Hoaxes, is the opportunity to explore some of the most outrageous ideas ever to gain traction in the public mind. It’s easy to make fun today, but some of these ideas were grounded in reasoning that, though flawed, eventually gave rise to the right answer. Then again, there’s really no defending those doctors who thought that woman was giving birth to rabbit parts.
