    Y’all don’t give yourselves near enough credit for what sounds “common sense” to you.

    It would look more like this.

      The reaction in that picture is also bang-on though, because Semmelweis got a huge amount of pushback from the medical community at the time, who took offense at the apparent accusation that they were so dirty they were killing their own patients.

    Huh. At first, I thought that was about rubbing the kitty with some amber.

    “Thales of Miletus, writing at around 600 BC, noted that rubbing fur on various substances such as amber would cause them to attract specks of dust and other light objects.” (Yes, that Thales.) It is still, or again, a popular demonstration, though we use plastic instead of amber. Amber in Ancient Greek is “elektron”.

    I’m pretty sure there was research done that showed that people who are hypothetically transported back in time, won’t be able to make any meaningful contributions to the era they go to. They will just end up integrating in that the society of that era.

    Basically if you go back in time to medieval Europe, you could introduce something like paperclips to society, but you won’t be able to introduce things like computers even if you know how they work and how to use them.

    Yeah, you can’t just lay down electricity, especially not practical electricity it requires a ton of diverse knowledge from many different studies. What I would do is give them the concept of using steam to power to spin wheels or create an engine. Then use gear ratios to show them how to scale it up. Idk if they had found neodymium magnets back then, but teach them how to use them to heat iron by spinning them on the end of a steam engine and you’re starting to cook with electricity.

    Again, getting to electricity from there is still a whole fucking chore. But hopefully you could rely on science to advance way faster from your advances than if you weren’t there.

    Actually, the most important thing you could give the greeks is the concept of the modern scientific method. That shit was invented so late and just skyrocketed science (literally) the moment it was refined.

    Just write a book about everything you remember about a null hypothesis, randomized blind trials, control experiments, variable control etc. if you can squeeze any bit of statistics out of your brain, even if it’s just making a graph, you probably advance the world by thousands of years.

      Probably 2 of the biggest reasons the Greeks failed to become a technological civilization are that their various feuding city-states never united in cooperation, but primarily that they were super into slavery for all their labor. They didn’t want to make slaves work less, then they would have time and energy to rebel and slaughter their masters. No, scientific advancement was simply for curiosity’s sake, not practical applications.

    Electricity works by moving electrons from point a to point b.

    There are different ways of acomplishing this. Easiest is to have an electrolyte between zinc and copper. Kids use a potato for their science class. Volta used cloth soaked in saltwater.

    Which is also why call it “Volt” and “Voltage”

    Me at the 19thC Royal Society, all cocky like: Matter is energy, E=mc^2

    Michael Faraday: interesting, how would I go about proving that?

    Me: no fucking clue. Something to do with spaceships, or massive bombs?

    I actually read A Connecticut Yankee in King Arthur’s Court recently. It’s one of those things where I knew the whole story going in because pop culture had remade it several times for both children and adults. I got Star Wars the exact same way. But I recently listened through the original on LibreVox.

    Twain apparently wrote it to poke fun at a friend of his who wrote stories about noble knights errant, which is why he creates an ancient people who are perfectly ignorant and perfectly gullible, that stories of “rescuing maidens from a giant” were extremely embellished stories of buying pigs back.

    Then there’s the entire aspect of a modern engineer teaching a historical people new technology. Twain makes a BIG deal of “Arkansas journalism” and convincing knights to carry advertising billboards with them which would have been very modern and American to a 19th century man. But also he manages to set up a printing press in a land that doesn’t understand pulp paper, a telephone network in a land that doesn’t understand electricity…in apparently a couple years?

    Me? I think I’m an above average candidate for this scenario, I’d die in a boiler explosion attempting to build a steam engine.

    imagine showing them the quadratic equation and they’re just like “why does this matter” and just being like “idk I barely passed”

    How do people in this day and age not know how electricity works? That’s like grade 3 science…

      Go back to a time where material quality and manufacturing processes couldn’t produce consistent quality and quantity of things needed to build a basic generator.

      Where will you get the permanent magnet, for instance? What will you demonstrate once you’ve assembled a basic generator? Going to make a light bulb? How about a voltage regulator? Think about the manufacturing processes involved in that, like pulling a vacuum for the bulb? I mean, it’s one thing to know that spinning a magnet in a coil of wire makes electricity, it’s an entirely different thing to actually build such a thing correctly and to convince ancient peoples to even help you and not kill you for witchcraft or something.

        Well, a simple thing to do once you have a coil and magnet is to hook it up to another coil.and magnet some distance away. You can then transfer the spinning action. Something simple to set up would be a fan.

        As for not killing me for witchcraft, plenty of folks want to kill me now for much more tangible reasons, so there really isn’t much to gain here.

        Copper and lodestone were some of the first materials refined from ores. You can also create a permanent magnet by getting a piece of iron struck by lightning.

        Once you have copper and a magnet you can use the electricity to make additional magnets out of iron.

        It’s also possible to make a magnet with a compass, a piece of iron, and a striking hammer:

        position the metal facing north, strike the southern end repeatedly

    Uhh… I’ll give it a try. Let’s first start by digging everywhere looking for this natural metal called “copper.” We’re gonna need that for conductivity. Then…um… I honestly don’t know what happens after that.
