    If you paid attention in high school you could bring mathematics up to about the 17th century, if you really paid attention you could even grab some stuff from the 20th (wtf vectors why did you take so long to figure out?) and the 19th.

    Plus there is just so much basic stuff you know. Used boiled and sealed water to clean a wound. Bleeding a person only makes them feel good for a bit and does nothing else. Steel in cement makes cement better. Or in the case of this picture zinc and copper and lemon.

      anything about sanitary practices faces a massive barrier of getting people to accept and implement it. I could tell ancient doctors to wash their hands, but the first time someone tried that in actual history they laughed in his face.

        Monarchs cares about power. Give the ruler some more metallurgy or siege engines first, so you have their favour. Then split the Royal Court’s physicians into two groups, one that washes their hands, and one that doesn’t. Do the same for leeches, bloodletting, hydration, etc. It’ll be hard to argue with the resulting death rates. And in the long run, you’ll have a much bigger impact by introducing empricism/A-B testing/evidence-based medicine than any one thing specific thing you could have done.

        But on the other hand, there’s a decent chance of you worked hard enough, they could probably get there at least a century or two after your death.

      That’s assuming you don’t either kill them all off with your 21st century germs and/or be killed because the church doesn’t like you.

          I scoff at your suggestion! We must compulsively dissect those unspoken assumptions. This is the internet, you see, where the most brilliant of minds gather to squabble about peripheral details so that no fun can ever be had. Yuck having fun!

      People were so moronic back then, even more than today, saying any one of those things would have you burned like a witch 😂

        You should research how people actually were. It will do a lot for your opinion of human nature.

        It makes me happy realizing that im not better than people in ancient Egypt.

          People in ancient Egypt also thought people before them were so moronic for not knowing which gods to leave offers to, so their priests could predict when the Nile was going to overflow, or having an actual living God as their ruler, capable of turning off the Sun on a whim.

          But what you should be proud of, is being able to read this, unlike most people in ancient Egypt, who had to pay a scribe to write or read for them.

            The Egyptian gods created the universe in their culture. They would not make fun of their ancestors for worshipping the wrong gods. That would be an absurd notion to them.

            Struting about because youre so much better than your ancestors is not an innate property of being human, regardless of how much you like doing it.

              Is that why they had slaves, because they considered everyone equal? Or did Ra’s worshippers stage bloodshed after bloodshed because they thought their ancestors were not wrong for worshipping other gods like Horus, Amon, Aten, and some more, and vice versa?

              Akhenaten had such disdain for everyone, gods included, that he proclaimed himself to be God Supreme, curiously one his ancestors used to consider just an aspect of Ra.

              Right, not innate at all. Good to know you don’t consider yourself better than a bunch of egomaniacal power hungry religious zealots 🙄

                Deep breathes can be used to stay calm. Theres value in humbling yourself. Nobody really deserves as much respect as they think.

                The Meditations is a really good book to avoid holding yourself too highly.

                  LoL. Guess you’re true to your nick, no high is too high? 😆

                  Humbling oneself is a nice exercise, being a doormat and seeing all past through rosy glasses is a life endangering attitude.

      Steel reenforcement of old European concrete would have been disastrous. They used limestone in the aggregate and cement and it would have eaten the steel in a decade or two.

      Steel, like the strong metal for weapons? You want how much of it, and throw it where? And what’s a “lemon”?

          Depends on where and when you’d go.

          They had “citrons” since 4000 BC or more, which came in many different shapes, some with no pulp and no acidity, which wouldn’t work for making electricity. https://en.m.wikipedia.org/wiki/Citron

          Lemons were introduced in Europe around 200 AD, and were pretty rare and expensive.

          If you went to biblical times and asked for a lemon, they’d likely not know what you meant, then maybe gave you a citron, which could be of the low acidity kind, then beat you up for being a liar.
