“Superposition is SO COOL!” This comment by a FlexSchool 5th grader was one of many enthusiastic chats, during a lively FlexFriday discussion with graduate student Felicity Hills about the limitations of our knowledge of physics. “Gravity is a good example. We have Newton’s laws and day to day, most of what we interact with can be described with Newton’s Laws. But for really large, black holes, Newton’s laws are no longer sufficient,” Felicity explained. “What we always do in physics is ask questions about things that sort of push on them: Why can’t we explain this? We want to add to the standard model. We do have a set of equations that explain the standard model, but we know those equations aren’t complete because there are things we can’t understand. We want to refine that and make a better theory.”
