Stonehenge Builders Used Pythagoras' Theorem 2,000 Years Before He Was Born (techtimes.com) 183

According to a new book entitled "Megalith," which was released on June 21 to coincide with summer solstice, ancient humans who designed Stonehenge followed Pythagoras' theorem 2,000 years before his birth, around 2500 B.C. The theorem states that the square of the hypotenuse is equal to the sum of the other two squares on the triangle. TechTimes reports: [The theorem] was developed by ancient Greek mathematician Pythagoras, who was born in 570 B.C. However, Stonehenge was assembled 2,000 years before his birth, around 2500 B.C. This theory suggests that these ancient humans were smarter than what people give them credit for. In order to use Pythagoras' theorem, they had to be really skilled at geometry.

"We think these people didn't have scientific minds but first and foremost they were astronomers and cosmologists," John Matineau, the editor of the book, told the Telegraph. "They were studying long and difficult to understand cycles and they knew about these when they started planning sites like Stonehenge."

      The governing principle here is not the establishment of a mathematical theorem but societies need for that theorem. Without the need there is no need of hypothesis to establish proof and create a theory. So driven by societies need for accurate measurement, that society must have advanced sufficiently in order to make use of the theory to keep it alive, especially prior to the printing press.

    The link sheds no light. But lots of ancient cultures knew right angled triangles. That does not mean they knew Pythagoras theorem as we know it today.

    I know an ancient Tamil formula that seems to be Pythagoras theorem at the first glance. "Make eight parts of the running length, and discard one part, add to it, half of the altitude. What you get is the hypotenuse". Instantly one notes, there is no quadratic term. It is a linear formula, so it is not a general Pythagoras theorem. It boils down to "when two sides of a right angled triangle is 4 and 3, the hypotenuse is 5".

    Nothing unusual. All they needed was an easy way to construct the right angle. That is all. The simplest way is the make a lasso with a rope ten units long, and mark off 3 feet and 4 feet, you can form a right angled triangle. If you make the rope hundreds of feet long, the angle will be accurate enough for the ancient construction techniques.

    Egyptians had been using the 3-4-5 right angled triangles to demarcate land holdings after Nile floodings 1500 years before Pythagoras.

    For aligning ancient temples, pyramids and other structures with East/West directions, the technique was ridiculously simple. Plant a pole, and mark the tip's shadow location at sunrise on equinox day and again the location at sunset. Line joining these two points is East-West. Use the 3-4-5 triangle from a 10 unit long loop of a rope and mark off North and South. Use plumb bob for vertical. You have a clean three axes Cartesian coordinate axes marked on the ground.

    Dont get me wrong. I am amazed they can identify the equinox and solstice days, that they can predict eclipses, form calendars, They were as intelligent and smart as any modern human being. 5000 years is, but a blink of an eye, in evolutionary time scale. But let us also note that what we mean by Pythogoras theorem today is vastly different what they were using back then.

      Equinox and solstice days are easy to find, as we know from the Nebra disk [wikipedia.org] and Goseck [wikipedia.org] and similar star observatories. All you need is enough time (e.g. a year).

      You choose a fixed place and mark the point on the horizon the sun appears each morning (and maybe the point it goes down). The most northward point is the point the sun goes up on summer solstice, the most southward point is the one it goes up on winter solstice. Half the distance between the two points are the equinoxes. The people around Goseck

        I'm sure there are constants such as Pi, phi, euler's constant, the golden ratio, and more that can be found in the pyramids' construction, as a consequence of geometry. That in no way is proof they understood the constants in abstract. In fact there's little evidence they did.

    Stonehenge contains right triangles; the right triangles obey the Pythagorean theorem; therefore whoever built Stonehenge must have known the Pythagorean theorem.

    But ALL right triangles obey the Pythagorean theorem (which is the whole point of the theorem), so this would be true whether the people who built them knew about the theorem or not.

      Not quite.

      A "Pythagorean triangle" is a right-angled triangle where the sides all have integer length. This guy claims to have found some of those, in particular there's a rectangle of stones that mark important sunrise/sunset events and moonrise/moonset events which, when you cut it in half, is Pythagorean.

      Which seems odd to me. If the stones are determined by the calendar events, that's the reason why they have those proportions, not Pythagoras' theorem. The builders may have discovered this integer ratio relationship and found it interesting, but I doubt it's the other way around.

      • Basically the put four stones around the circumference of a circle, which forms a rectangle. So if all three sides of a right triangle happen to be integer values then it's Pythagorean? But just decrease the length of each integral unit until you it's fuzzy enough and you can't measure it accurately, and any right triangle drawn on the ground can be Pythagorean.

        To me, the Pythagorean Theorem is about a^2 + b^2 = c^2, even if not an integer, and a proof that this is true. Merely noticing that 3^2 + 4^2 = 5

      Quite.

      Maths is not an inherently intellectual-only exercise. It can be determined to within a human margin of error quite easily by empirical evidence.

      The same claim goes to the pyramid-builders. But the desert is littered with collapsed and bad pyramids that weren't right or were changed mid-construction. And those are just the ones that got left rather than "Rip it up, it's wrong, that's a billion tons of stone, we can re-use it"...

      Though I don't doubt these people were not just Neanderthals bashing clubs against their head, they didn't formalise mathematics in this fashion. Pythagoras did, which is why we know his name and call him a mathematician.

      You have to recognise that Stonehenge proper was 3000-2000 BC. Mesolithic posts on the site align to a lunar calendar thousands of years before that.

      For thousands of years, people maintained a site with significance to their astronomical observations. Yes, for religious purposes, but they weren't idiots. Likely these people had intelligence not vastly different from our own, but they lacked a more formal education process. The ability to sit in a classroom for 18-20 years and be taught every day is the only thing that's changed. These people weren't stupid, just not formally educated. Plenty of people even today operate on the exact same principle!

      How many adults, now, today, could tell you what Pythagoras' Theorem was, state it, understand it, apply it and see it's application to places like Stonehenge? It's by far not everyone.

      How many adults, now, today, are going to build something that's still standing in thousands of years, and how intelligent (collectively) would everyone who worked on it have to be to do that?

      I find it quite insulting that people think even Stone Age man was some thick-headed caveman. And that EVERY Stone Age person was that thick.

      Hilariously, I watched a series on TV a few years ago where a group of people tried to live in an isolated area with no modern facilities and they failed MISERABLY. Literally, they ate through their initial stock of food, they couldn't build a shelter, meat was left to go rotten for days with no preparation and they were SURPRISED by that, they trekked miles to get water and came back with almost nothing, not even food gathered along the way, and when snow hit, they were all evacuated to safety because they didn't bother to make any preparations.

      Just being "modern man" doesn't make us collectively intelligent. There are outliers whose knowledge benefits us all, while half of people are of "below average" intelligence (by definition - if you don't understand that, nor do half the population!). That a few thousand years ago, not long enough to have biologically changed us very much at all except under extreme evolutionary pressure, there were people capable of taking a reasonable guess at the length of a side of a basic engineering project? Yeah? And? So what?

      We are doing these people a disservice. It's probably why a lot of people just assume that dinosaurs and cavemen lived together.

      These people probably didn't even have TIME to sit around and think, let alone formerly school, but it doesn't mean they were stupid. They could probably only burn wood, maybe a primitive oil for light (outside of full moons) - hell we don't know what they might have been doing of an evening, they may be much cleverer than we thought. But likely the night was a loss and most of the day was used for more essential tasks like surviving and gathering food and making weapons.

      You're not telling me that you're surprised a Bear Grylls existed back then who had mastered his art after generations and had time to sit and think, even if his village mates were still worshipping trees?

      Pick a modern human couple at random, put them back in that environment, and we'd likely not be able to replicate anything of Mesolithic mathematics, cosmology, survival skills, etc. for dozens of generations (if they even live that long).

      • Well, but after building Iglus every few month year after year, he surely knows PI is closer to 355/113, don't you think so?

  • I think they're all hallucinating. If I hold my cat up in the air her head perfectly blocks out the Sun. Coincidence?
  • The article says that even though they didn't write, didn't build houses, didn't settle, didn't have a common language, the builders of stonehenge were fine mathematicians and geographers and were able to set up giant right-angled triangles on a geographic scale. And this huge knowledge didn't reach us because it was destroyed... by Christians.
    • didn't build houses, didn't settle, Strange that we found so many relicts of houses and villages ...
      didn't have a common language Extremely unlikely.

      And this huge knowledge didn't reach us because it was destroyed... by Christians.
      Only in rare circumstances, most was long forgotten and underground before the Christianization even started.

      There are nice BBC movies about recent stone henge research, you find them on youtube. The people living there traded with people from spain, central europe, north italy an

    I could scatter a bunch of coins on the ground and an observer could infer all kinds of relationships based on the distance between the coins. The observer might, after a while, go wildly overboard and start proclaiming all this was by design. They might even start fudging and massaging the facts to fit this hypothesis - maybe particular coins follow a pattern of sorts but others don't, so let's discard those coins and focus on the ones that do etc.

    I really don't see this being far removed from what is being suggested by the article, that standing stones in the British Isles are positioned in a way which is pythagorean. There are hundreds of standing stone circles all over the isles. It would not be hard to cherry pick some of them and shoehorn the hypothesis into. It's the sort of pseudo archeological garbage that Graham Hancock has been doing for years.

    • I'm always reminded of people who were convinced that crop circles had to be some magic alien creation until a couple of pissed farmhands showed everyone how they made perfect circles and spirals with a stick and a length of rope.
      • You're leaving out the part where crop circle design has gotten way more complicated over the years and the classic farmer explanation no longer applies to many of the more complicated "circles".

    • Eh, it'd be more surprising if it didn't involve ratios in construction. If you read on historical building techniques, the easiest way to do things well before you have rules to measure with is ratios. So if you're going through the trouble to build some big thing out of stone when that is pretty difficult, of course you're going to plan it all out with ratios or something convenient (which is why historical measures are based off of body parts) and subdivisions thereof (12 inches to a foot is because yo

        The article was talking about a couple of things - the construction of individual sites and another suggesting disparate sites were actually laid out at exact positions to form a triangle over a map for some reason. It's the second I was referring to. Britain has hundreds of circles and there are more dotted around Ireland, France etc. It straightforward with that amount of points to drag some geometric pattern out, discard the remainder and proclaim it was their intent to make a pattern. It's a common them
  • Quick, someone test the asinine modern druids who claim religious rights over it, to see if they know the theorem.

    Test the politicians who roll over and let it happen too.

  • I'd like to think the Stonehenge builders were thinking so abstractly as to conquer up Pythagoras' theorem two thousand years before that Greek genius did, but I have my doubts. When building the Pyramid of Khafre (2558-2532 BC), the Egyptians would have used a rope with knots tied at intervals of 3,4, and 5 (Pythagorean triples) to guarantee a perfect right angle. Their use of concrete numbers aligns to the Pythagorean Theorem, but is not evidence they knew the Pythagorean Theorem. Similarly, the concrete
