I found an article that said “The microwave was invented to heat hamsters humanely in 1950s experiments.” And I thought, no it wasn’t. …was it?

Pull down the description for thorough references and credits.

Thanks to James Lovelock for his time! His latest book is Novacene: https://amzn.to/3hmKsWz [that is, of course, an Amazon affiliate link]

I did consider whether to do an extended interview with Dr Lovelock, but the Science Museum has already done far better than I ever could:
