Welcome back to the Information Entropy Podcast where this week we continue our exploration into the electromagnetic spectrum. Given the extreme heat (transmitted through infrared radiation… see its relevant ramble!) the boys start the episode exploring heat waves, heat domes, British summer heat, and the El Niño–Southern Oscillation events and what that even is. After that, attention turns to microwaves… ovens and the waves themselves! Tom questions whether microwave ovens are small boxes of magic and explores how they heat your food. Mitch teaches us about radar systems and the other extremely cool uses in everyday life for microwaves!
