  • No they don’t (necessarily))??

    Notice how they didn’t spread the cookies evenly on the tray? If they had, it would’ve resulted in squares - not hexagons. On the left, some cookies look more like squares already.

    Hexagons are just one possible way to tile the plane without gaps. The only reason bees use hexagons is because tiling a plane with hexagons results in the lowest possible total perimeter for equally sized shapes. And bees build the edges of their comb shapes using wax, which is expensive.




  • I just think of the definition of a derivative.

    d is just an infinitesimally small delta. So dy/dx is literally just lim (∆ -> 0) ∆y/∆x. which is the same as lim (x_1 -> x_0) [f(x_0) - f(x_1)] / [x_0 - x_1].

    Note: -> 0 isn’t standard notation. But writing x -> 0 requires another step of thinking: y = f(x) therefore ∆y = ∆f(x) = f(x + ∆x) - f(x) so you only need x approaching zero. But I prefer thinking d = lim (∆ -> 0) ∆.


  • Not necessarily, many small animals have an utterly insane metabolism making them eat their entire body mass in a couple of days. For example, hummingbirds eat the human equivalent of 150,000 calories per day.

    Larger animals typically cannot afford to spend so much energy - there is just no large food source that has sufficient calory density.






  • How do you install kindness and affection? They’re not on the AUR:

    [yetAnotherUser@discuss.tchncs.de ~]$ paru -S kindness affection
    :: Resolving dependencies...
    error: could not find all required packages:
        kindness (target)
        affection (target)
    

    I have, somehow, found love packaged though. But it’s not true love. It’s LÖVE (a 2d game engine) spelled with an ASCII typeset so I’m pretty sure I have installed the wrong dependency.
