  • It’s a misleading legend, but the note at the bottom tries to clear it up a bit. This map seems to more be like “We took the range maps of 238 species of fish and overlaid them. The red area is where practically all of those range maps of each 238 species of fish overlapped.” Of course there are other fish, but they were not included here because the map maker didn’t have the right kind of dataset for them. To me that seems to indicate that this map isn’t so much a map of actual biodiversity measured, but the potential for biodiversity of the region. Given that it’s fish, I guess we shouldn’t be surprised that this area is somewhere between/near the northern continent’s biggest river, a large gulf, and ancient mountain range, and a coast with a strong warm current (for now…).


  • 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 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.

    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.
