  • It didn’t come together like a granny knot, which I understand to be just a square knot with the orientation of one half flipped. The knot I learned wrapped the free end around the base of a loop and pulling a section of that free end through it to create another loop. It was unbalanced for the same reasons as a granny knot though and probably very similar.

    The knot I tie now is basically a square knot where the “top” half is formed from two loops. Admittedly the knot I tie now, would have been much more difficult for toddler fingers than the knot I learned as that toddler.



  • I guess the children can’t read, won’t read, or will just get strangely antagonistic whenever anyone suggests that their ignorance is not a virtue or particularly unexpected. People can’t know everything from birth. Young people learn about stuff as the age. You’re probably one of the lucky 10,000 multiple times a day. Young people not knowing about something is not and never has been a sign that something is being forgotten. It’s just the way it always has been. They haven’t forgotten, they just haven’t discovered it yet. No one is surprised or worried by this except you.


  • I bought SUSE Linux once upon a time. It was a physical CD and the packaging that I paid for. Maybe a little support was bundled, probably not. That was a time when the internet was slow for most and not an option for others, wifi wasn’t ubiquitous (and if it existed, good luck getting the proper drivers loaded without internet), live distributions weren’t really a thing yet, booting from usb was finicky and unreliable, and the install CDs would have the entire OS and basically all the software you could want to install bundled. These would have been the days before the fall of Napster and the rise in other “Linux ISO sharing tools”. Ubuntu would even mail you like a half dozen physical CDs and some stickers just for asking and promising to share them in your community.

    There’s nothing wrong with buying the physical things or paying for support. That’s not what this meme is showing though.

    If you’re going to be snarky about units, at least get the significant digits correct. The infographic gives 100°F as the temperature. If I had to guess I’d say that wherever that number came from, it’s precision is much less than a whole °F, but for simplicity let’s just say that the precision is a whole number, no decimal places in the precision. At that precision 37.5°C and 38°C are both also 100°F. There are 9/5 °F for every °C after all. If you’d said 37.7°C I wouldn’t have even commented. But that was one decimal place too far (and being too lazy to find the ° symbol or type out degrees).

    You’re all probably saying, “Who cares? Why do you care? Aren’t you just being any even more annoying pedant?”

    I do. I don’t know. Probably.

    But, if you’re going to be a smartass, you better at least try to be smart about it.

    It’s an optical illusion. By definition their isn’t generally anything YOU would call erroneous about any optical illusion, I’d guess. The fact that the text is difficult bordering on impossible to read at some angles is the perceptual error. Stop ignoring obvious interpretations to support your pedantic trolling.


  • That’s an unhelpfully restrictive definition of illusion that is itself illusory. An illusion is also:

    A sensation originated by some external object, but so modified as in any way to lead to an erroneous perception; as when the rolling of a wagon is mistaken for thunder.

    The text is hidden or revealed through a change in perspective. That is the illusion.



  • How is a zig-zag numbering any less valid than any other method? Your mapping a two dimensional space with what is essentially a line. Sometimes it doesn’t make sense for there to be discontinuities in the numbering, as one would have to do if the numbers always incremented in the same direction. Would you prefer that the numbers follow the path of a Hilbert Curve?

    To answer your question though, surveyors have been using this method to number sections of land for much longer than you or I have been alive.


  • Because vector graphics take up much less space. That’s the joke.

    Now I’m going to put the joke out of it’s misery.

    Most of the illustrations, formula, tables etc. in a math book could be vector graphics, most of them were in 90% of the upper level math text books I’ve ever had, usually in only 2 colors. Many math formulas can be represented and formatted directly using only Tex or LaTex. Mostly physics and math involving more than two dimensions would have more raster images, even color. But it’s not like the publishers are going to be handing out PDFs with original vector graphics embedded. That would make high quality knockoffs trivial.
