I just posted a new episode of my Science Teaching Tips podcast – Electrifying Ideas. My old boss, Paul Doherty, is a great storyteller, and this is one of the stories of science that he uses to explain the history of science. The ancient Greeks knew about magnets, and they knew about electricity, too. But it wasn’t until the nineteenth century that a connection between the two was discovered. Paul tells the story of how a professor made the connection . . . which led to modern motors.

Episode 38: Going to the Dogs

This one features my old boss, Paul Doherty, talking about how polarization was invented, and what it has to do with dog urine. Paul’s a great storyteller, and I love this story — give it a listen!
