Microwaves never cease to amaze me. If I were in some alternate timeline where they weren't ubiquitous, and you told me such a thing would soon be in everyone's homes, there's no way I would believe you. I mean, people putting their foods in a Faraday cage and then pointing a cavity magnetron at them to cook them? It sort of sounds far-fetched. Bimetallic strips are also so awesome. Every time I hear that little 'click' noise, I think about them. Is there a term for knowing just enough about the technology that underlies daily life, that you feel mildly absurd using it for mundane tasks?
