Maybe I'm weird, but I think about that stuff all the time.Psinter said:If you were moved in time to the middle ages, would you know how to recreate current technology? I wouldn't. Theoretically I know how some things work more or less, but how on Earth do I build a transistor in the nano meter scale in the middle age?!
As a matter of fact: "How do I even build one now in this time in the nano meter scale?" Is the question.
Makes you think.
I think I would be mostly lost. I would probably give up on the transistor because I would be lost on making the more simpler things first. (I have a slight bit of knowledge regarding transistor fabrication, but not nearly enough to recreate one in the back shed.)
I'd start with something a bit simpler like an electric generator. I could make one, maybe, if I had some appropriate wire laying around, but that's not going to happen in the middle ages. How do I make the wire? I would need to get some copper first and cold roll it into something very thin. (Maybe I could get a blacksmith to help me make the tools for that.) Then I would have to apply a thin coat of enamel insulation on it. Where in the world do I get enamel? How do I apply that to the wire ?! And what about magnets? The ones I could make would be crude and weak at best.
