I promise this story about microwaves is interesting.

Tom Scott investigates whether the microwave oven was invented to reheat frozen hamsters in 1950s laboratories, tracing the urban legend back to cryobiology research by James Lovelock and R. K. Andjus, and interviewing Lovelock himself.

Answers: Was the microwave invented to heat frozen hamsters?

• microwave oven invention history
• cryobiology and animal reanimation
• microwave diathermy heating
• James Lovelock biography and inventions

What it concludes

• The microwave oven was not invented to heat hamsters in 1950s laboratories, but Percy Spencer realized radar could cook food.
• Scientists at the National Institute for Medical Research successfully reanimated frozen hamsters and rats using ice, propylene glycol, and microwave diathermy.
• Microwave reanimation of frozen mammals does not scale up to humans due to the size of the animal and antifreeze diffusion rates.
