    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.






  • Whoa there. Are you seriously gatekeeping sci-fi? Don’t be a jerk.

    Just the MCU characters with an obvious sci-fi backstory: Tony Stark, Hulk (an actual scientist), everyone in Guardians of the Galaxy. Even Thor is actually an alien using Sci-Fi tech. Bucky Barnes is a cybernetic super soldier. There’s the Nazi scientist from Hydra that transferred his consciousness into a computer. Fucking Vision and his love story with Wanda. Black Panther may mix in some mystical drug, but his suit and all the other toys are all science fiction.

    I’m not arguing that ANY of these are great science fiction stories, but they are still undeniably science fiction. Sci-fi stories are often also something else: horror, action, humanist, dramatic, comedy, or all of the above.

    Not every science fiction story needs to use the obvious sci-fi tropes either. Ursula K Le Guin wrote a bunch of very influencial science fiction stories that you could be forgiven for classifying as fantasy and have very little shiny tech in them.




  • You seem to be implying that you are somehow more entitled to that public space than kids. Sounds like something an entitled little bitch would say. Are you an entitled little bitch? Public space is for the public, ALL the public. If let your own hangups lead you to bullying the most naive and impressionable of us, then you are sacrificing other people’s freedom. And if you are people like this then I say, “fuck you too”. The social contract of public space doesn’t entitled you to be unbothered by other people.

    To be clear I am in no way excusing parents that do not actually parent their children, especially in public. However the logic of the above comment is just a bunch of “get off my lawn” anti-social ME generation boomer energy. Also, kind of telling that the parent commenter just doesn’t see the parallels between their entitled attitude and everyone else’s entitlement. It’s a public space, if you can’t be compassionate, you don’t deserve it any more than anyone else.
