    I wouldn’t be taking any credit for most of this. This poster would be better served if I could find Leonardo Da Vinci or something and give it to him.

    “Putting electricity through quartz changes it’s shapes, that’s clocks” 😮 what?

    “Make aerofoil go fast and you can fly, here’s a vague picture of a wing.” Excuse me?

    I think I can pull off finding mouldy food and hot milk so I’ve got that, I guess.

    Saying that, if I made a time machine, I imagine I would understand the things in this poster.

      “Spin a large magnet near some copper coils, you’ve invented an electrocution device!” I think having a vague idea about some of these things is more dangerous than not knowing anything. Lots of stuff about electricity and nothing about grounding and insulation.

        “you can get insulin from dogs and pigs by tying the pancreatic duct!”

        Get rid of the wing and show me where to find this bit inside a pig and I can save lives, we can just wait for the wright brothers to figure out flying again.

    Polaris is absolutely NOT the brightest star in the sky. Not even close.

    How to actually find it: Find the big dipper (I know you know what it looks like). Take the two stars at the front end of the “cup” part. Draw a line through them “up” and out of the cup until you hit a star. That’s it.

    A lot of this I couldn’t do but… a lot of it I probably could. I’ve designed and built quite a few weird machines for people who were paying me, but probably the simplest thing for me to make in preindustrial times would be a battery and an electric motor.

      Congratulations, you’ve just earned a stoning by the town mob.

      Unless you can make an electric motor that goes with your electric generator, you’ll just be killed as a witch for making a device that hurts people with invisible energy.

      Also, good luck not just getting brutally murdered for being a weird person that doesn’t speak the language and is dressed funny. For like half of human history, even describing a magnet would be nearly impossible, let alone finding enough magnets of similar size and strength, and having enough money to purchase those rare items and thinly drawn copper.

      If a guy came up to you today, dressed funny and talking in broken Spanglish or something asked you for a small loan so he could buy some deuterium and promethium to make a fusion-tap-quark drive so he can advance humanity, you’d probably run away. A thousand years ago you’d probably just have been stabbed on general principles.
