Study math for long enough and you will likely have cursed Pythagoras’s name, or said “praise be to Pythagoras” if you’re a bit of a fan of triangles.

But while Pythagoras was an important historical figure in the development of mathematics, he did not figure out the equation most associated with him (a2 + b2 = c2). In fact, there is an ancient Babylonian tablet (by the catchy name of IM 67118) which uses the Pythagorean theorem to solve the length of a diagonal inside a rectangle. The tablet, likely used for teaching, dates from 1770 BCE – centuries before Pythagoras was born in around 570 BCE.

    literally 90% of human history has gone unrecorded, and what has been recorded usually gets destroyed, ransacked or deliberately destroyed, Caligula’s pleasure barges, Tower of Babel, Library of Alexander. Humans have tried to keep knowledge retained. and some people take that personally.

    remember when ISIS was at its peak they were just destroying artifacts like it was a kid in a candy store. And that’s just been in the 35 years I’ve been alive.

    when Rome fell it took another century for civilization to rediscover the technology and applied lessons used then.

    and im a dumb idiot, I’m just making a broad skim, if you could ask a historian they’d likely tell you all the things humans have lost, purposefully destroyed or forgotten along the way.

      It’s even more amazing than that in the case of Rome. To cite just one example, by the time of Constantine I in the mid-300s CE, Rome could support armies totaling 650,000 men. The logistics and organization required to do that are staggering. After the fall of Rome, it would take until the time of Napoleon’s Grand Armee in the early 1800s before numbers like that were fielded again. Even today, there are relatively few countries with an active military force of that size. They weren’t just sitting around either. Rome was always fighting someone. It speaks to the ability of ancient peoples to organize and support truly massive endeavors and sustain them over literal centuries. I mentioned Napoleon’s Grand Armee earlier. It was large, but it only lasted for about 5 years.

      So, yes, a ton of technology was lost for a long time, both physical and social/organizational.

        And during the second Punic war, when Rome mostly just controlled the Italian boot, Hannibal ravaged the peninsula for a decade but Rome just kept raising more armies to fight them. You could say that war wasn’t very well understood at that time (like Hannibal was very good at battles, but couldn’t turn that dominance into its own advantage), but it’s still crazy to me that Rome just had an enemy army just roaming around, surviving on plunder and foraging, destroying the armies Rome sent to oppose it, but otherwise Rome was still able to function as a state to the point where they could raise, organise, equip (actually, they might have had to equip themselves at this point, I think the Empire providing that was one of the innovations they later started), train, move, and feed armies despite it.

            And the final stage came years after the previous one had already beaten Carthage because they had the audacity of continuing to be more successful than Rome (in richness of the city), so they had to go back and completely destroy it and enslave the population that was left after the siege. And by destroy it, I mean they literally burned down the wooden parts and carried off the stones that couldn’t be burnt and forbade anyone to make a new city in that location.

    Reminds me of the mediaeval nun who erased a manuscript by Archimedes who was laying out the basics of calculus long before it was formally “invented” by Newton and Leibnitz because she needed space to write prayers.

        It was on parchment I believe, it was pretty common in the middle ages to scrape the ink off those and reuse them.

          For anyone interested, that’s called a palimpsest.

          a manuscript or piece of writing material on which the original writing has been effaced to make room for later writing but of which traces remain.

    What? Why? @Salamendacious@lemmy.world would you care to elaborate? Who curses Pythagoras? Fourier? Sure! Laplace? Fuck that guy AND the goat he rode in on! And don’t get me started on Fermat and his silly margin note joke. But Pythagoras?

      Unless OP actually wrote this article, they aren’t saying that. The post text body is literally just the first two paragraphs of the article.

        If OP actively copied it, and doesn’t give any indication that it’s plagiarized from the article, then OP can damn well defend it.

          I mean…do you not click on the comments sections of articles here? Standard practice is to copy some or all of the article to the text body of the post. I feel like maybe you either need more or less coffee/tea today. Take a deep breath my dude.

            Clearly I do.

            In that case I don’t follow the standard of stealing content when I post something.

              I don’t follow the standard of stealing content when I post something.

              It’s not stealing, it’s putting some of the info in the post. Most people aren’t going to actually read the article, so for those people, posting some/all of the body of the article gets them to actually read what was posted.

                I do choose weird hills to fight on, don’t I?

                Let me try this another way, this time with less sarcasm.

                1. The websites we link to generate revenue by displaying ads. If we copy the important parts of the articles, and put them on lemmy with the link, then, as you also brought up, people won’t want to read the original article as well. That results in fewer views and less revenue for the author. Is it the same as holding a gun to the author’s face and robbing them? Of course not. But I also don’t think it’s fair to the author either.
                2. It’s copyright infringement. Plain and simple infringement. If you copy all the relevant parts and don’t offer additional content, like commentary, then the fair use clause is really hard to argue. How copyright attorneys are going to handle getting content taken off the feddiverse is a different thing, but it is still copyright infringement.

                Why not reduce the posting rate, and take the time to just write a short enticing description instead?
