If you’ve ever been skiing, you might have wondered how your skiis and the layer of water interact. What would happen if the slope was made out of wood or rubber? Or how would you make more snow in the most efficient way if it all melted away? These are the questions that comic artist Randall Munroe thinks about in his book How To: Absurd Scientific Advice for Common Real-World Problems. He answers these hypothetical scenarios and other everyday questions—from charging your phone to sending a digital file—with uncommon solutions. Munroe joins Ira to talk about how he comes up with his far-fetched solutions and why “…figuring out exactly why it’s a bad idea can teach you a lot—and might help you think of a better approach.”
Plus: Researchers have long known about the connection between concussions sustained on the football field and chronic traumatic encephalopathy, or CTE, a neurodegenerative illness caused by repeated head injuries. But another group of researchers wondered—what about the hits that don’t result in a concussion? They found that even when a player didn’t show outward signs of having a concussion, their brains were showing symptoms of injury. Brad Mahon, associate professor in the department of psychology at Carnegie Mellon University, and Adnan Hirad, MDPhD candidate in the Medical Sciences Training Program at the University of Rochester, share the results of their investigation into the unseen impacts of head injuries on football players.
