    You know how geese fly in a “v” shaped pattern in the sky? One side of the “v” is usually longer than the other. The reason for that is that there’s more geese on that side.

        And it’s merely a hypothesis, there is no proof. Also we can assume that chemical plants are aware and have taken precautions, but it still happens. Back in the day it was speculated that chemists caried microcrystals around in their beards. This problem has been around for a while. One of the coolest hypothesis has been put forward by Rupert Sheldrake. He thinks that there is something in nature akin to memory. A force of nature as you will.

      But I’ll give you one of my favourite obscure-ish fact instead: baby sloths are so inept, they sometimes mistake their own limbs for tree branches, grab hold of them with one limb, let go of the actual branch, and fall out of the tree

    Ancient Egypt was ancient before it ended. The time when Cleopatra ruled is about as close to today as it was to the first pyramids.

      It’s actually even wilder than that.

      The earliest know pyramids date back to around 2600BCE, and Cleopatra reigned around 50-30BCE, so her reign is closer to the modern day than to the first pyramids by about 600 years. One of the earliest surviving pyramids, Djoser, was built by Imhotep (with help, I assume) during a period called the Third Egyptian Dynasty meaning, as it’s name suggests, the unified Kingdom of Egypt was already well-established by the time it was built. The First Dynasty started about 3100BCE so even ignoring the proto-Dynasty period of Egypt, that’s pretty humbling: if you drew a timeline with the founding of Ancient Egypt on the left and the founding of OnlyFans to the right, Cleopatra would be three-fifths of the way along it.

      One of my favorite facts is that while the first pyramids were being built, there were still Mammoth roaming some northern European regions (never checked whether this is true or not but I’ve heard it so many times that I want to believe it is true)

    Bedsheet thread counts have been artificially inflated for years by the shifty linen companies counting individual fibers that the threads consist of as threads themselves. It’s become a meaningless number, since there is zero regulation. If you want a nice thick heavy cloth, GSM is the number you want, but most companies won’t share this (looking at you, The Company Store) because they obviously don’t want you to know how thin and flimsy their products really are before you buy them.

            I misstated the definition a bit, although in real world terms a higher GSM does often manifest as a thicker cloth. GSM stands for grams per square meter. It measures how much fabric weighs in a given area. It is a weight rating, not a thickness rating.

            Higher GSM means denser, heavier fabric. Lower GSM means lighter, more breathable fabric.

            General guide:

            120–140 GSM = lightweight (summer sheets, thin shirts)

            150–170 GSM = medium weight (jersey sheets, linen duvet covers)

            180–250 GSM = heavier weight (flannel, winter bedding)

            GSM helps compare feel and durability across materials, but thickness will vary by fiber type.

      Also, the word doublespeak isn’t from Orwell. In Nineteen Eighty-Four he used the term Newspeak, meaning a sort of clipped form of language designed to limit expression of thought, and doublethink, the practice of holding two contradictory thoughts at the same time and believing both to be true, but he never used the word doublespeak.

      Interestingly though, it actually predates Nineteen Eighty-Four, but nobody really knows who coined it exactly.

    Eric Blair was a Trotskyist who wrote
    Animal Farm and 1984 to spite Stalin,
    as Stalin turned on Trotsky,
    as Trotsky was a one-world-government proponent,
    (with Moscow as its capital),
    with the argument that capitalist nations would do anything
    to isolate and destroy socialist nations,
    whereas Stalin thought that socialism would bring the
    Soviet Union enough success to defend itself.
    This had far-reaching consequences for
    Eric Blair who was participating in the
    Spanish civil war of 1936 to 1939,
    having joined the Trotskyist resistance group
    and saw the Stalinists resistance group turn on them
    and outright attacked them.

    If you catch a frog in between your hands and quickly flip it around, you can get the frog into a kind of paralyzed state called ‘tonic immobility’.

    Here is a photo from Wikipedia:

    Frog stuck in tonic immobility

    OK, well, many years ago I was very interested in this phenomenon and decided to look into the literature.

    I found a paper from 1928 titled “On The Mechanism of Tonic Immobility in Vertebrates” written by Hudson Hoagland (PDF link).

    In this paper, the author describes contraptions he used to analyze the small movement (or lack of movement) in animals while in this state. They look kind of like torture devices:

    OK, but, that’s still not it… The obscure fact is found in the first footnote of that paper, on page #2:

    Tonic immobility or a state akin to it has been described in children by Pieron
(1913). I have recently been able to produce the condition in adult human beings.
The technique was brought to my attention by a student in physiology, Mr. W. I.
Gregg, who after hearing a lecture on tonic immobility suggested that a state
produced by the following form of manhandling which he had seen exhibited as a
sort of trick might be essentially the same thing. If one bends forward from the
waist through an angle of 90°, places the hands on the abdomen, and after taking a
deep breath is violently thrown backwards through 180° by a man on either side,
the skeletal muscles contract vigorously and a state of pronounced immobility
lasting for some seconds may result. The condition is striking and of especial
interest since this type of manipulation (sudden turning into a dorsal position) is
the most common one used for producing tonic immobility in vertebrates.

    Apparently this or a similar effect can be observed in humans too?! In this paper, the author himself claims to have done this and that it works! I tried to locate more recent resources describing this phenomenon in humans but I could not find them… Is this actually possible? If so, why is this not better documented? Or, maybe it is better documented but understood as a different type of reflex today? Not sure.

        Ha, maybe! I don’t remember if I ever saw a 180 flip. This is the closest I could find from a quick search: https://www.youtube.com/watch?v=zZpIglVnYuY

        If you have a video with the 180 degree flip I would really like to see it. This context seems like a plausible place to see such a move in modern days. I would imagine that in some martial arts this effect would be well known.

          I don’t think anyone was bent over at 90° in the video?

          Regardless, that video is incredible; sending it to my ex-Evangelical partner immediately.

      Much as a 12oz steak won’t weigh exactly twelve ounces when served to you after cooking them a 2x4 piece of wood was nominally that measurement prior to the kiln drying process.

        It’s more that they used to be shipped 2x4 unfinished, and would be planed smooth on site. Once the equipment and distribution was able to do the planing before it got to the customer, they had so much established practice that the installed timber would be smaller, they had to keep to what people were used to.

    the roslagsbanan commuter rail is the only actively used 2 ft 11 332 in railway in the world.

    …honestly, with a wikipedia article that extensive it hardly qualifies as “obscure”.

    so, bonus:

    the siljan area of sweden has a history of building observation towers:


    the tower in the black-and-white photo, which started this trend, was financed by a man who made a fortune making and selling multiplication books. basically like books of logarithm tables but only for multiplication. 1×1 to 9999×9999.

    also that entire area is europe’s largest meteorite crater:
