Conduction Memes

Physics teachers really be out here branding their palms with metal objects just to prove a point! 🔥 That sizzling sound when they grab a hot metal rod and go "See? Heat transfer in action!" while their hand is literally cooking. The First Law of Thermodynamics clearly states energy can't be created or destroyed, but it doesn't mention anything about your teacher's pain tolerance being inversely proportional to their enthusiasm for demonstrating conduction! That hand tattoo is basically a badge of honor in the physics world - if you haven't permanently marked yourself explaining thermal conductivity, are you even teaching thermodynamics?
