    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.

    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.

    Diamonds aren’t stable and will eventually, over billions of years, decompose from their cubic molecular structure to carbon’s more stable form, graphite, which has a hexagonal molecular structure.

    Oh, here’s another good gemstone related one!

    Amethyst and citrine are both quartz varieties, and if the color source happens to be from traces of iron in the crystal lattice, one can be turned into the other. Heating amethyst can make citrine, and irradiating citrine can turn it into amethyst. This is because the only actual difference between the two is the valiance level of a specific election in the iron atom giving the stone its color.

    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.

      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)

    Several popular graphing calculators from Texas Instruments, including the TI-83 and TI-84, have a display resolution of 96*64, but only 95*63 pixels are used for graphing.

    However, the earlier TI-81 did use all 96*64 pixels. The rationale for this change was to establish a central row and column for the axes and a central pixel for the origin. The cursor could only move pixel-by-pixel, and since the axes and origin would end up “between” pixels on the TI-81, they were inaccessible by the cursor.

    There are more hydrogen atom in a single molecule of water than there are star in the entire solar system.

    “If you tell a lie big enough and keep repeating it, people will eventually come to believe it.”
    “The truth is always stronger than the lie.”

    One is a quote made by Joseph Goebbels,
    the other is a paraphrase of a paraphrase
    of a quote made by Joseph Goebbels,
    with the “In British culture” part missing.

    Guess which one is which.

    (P.S. I disavow German fascism.
    It’s just the more I learn about the US or UK,
    the more I’m surprised that fascism took hold in Germany… (first.))
