  • I don’t remember all of the details, but I thought it was essentially the water’s surface tension that foots the energy bill when climbing a paper towel or a capillary in a tree.

    The surface of fluids like water are unhappy. Molecules on the surface would much rather be deep in the fluid because on the surface they have “dangling” Van der Waals & polar bonds to one side. You can calculate the potential energy of the surface due to all of those dangling weak bonds, & that’s the energy that is used to climb a capillary (the energy isn’t free).

    I could be misremembering though, I admit. School was many years ago…

    If it’s a topic I’m super passionate about & there’s no community on Lemmy then sure. But I’m not going to start a new Lemmy community every time I want to post a random dog photo or whatever.


  • GrappleHattoRetroGaming@lemmy.worldDo you leave your consoles on?

    In ye old’n times we would leave the console on as a stop-gap way to save the game between in-game save opportunities. Because ye old’n times game design philosophy believed that the added difficulty of crazily separated save points was “fun”.

    In modern times I sleep the hardware if I expect to be back within <24 hrs, and power off if I expect to be longer.

    (Thank god for saving memory states in emulators!!! Elsewise I probably wouldn’t play retro games at all.)
