  !Of course you get an ice cream cone for the swimmer too! You’re not a monster!<

    Now I want to see someone swimming with a cone of ice cream in each hand.

      You want me to wear my swim trunks or get a bikini.. Warning before your answer: only one body type has the bouyancy to pull it off.

  I spent way too long trying to figure out why the guy and the ice cream shop were flying, and how he would move horizontally in he air…

    I couldn’t tell what I was looking at until I searched for an explanation. It’s supposed to be a beach:

    I was more like: but if he choses the alternative paths, he doesn’t get the ice cream - that doesn’t make sense! Then I understood our priorities differ.

  It is simply polite to include a link to the original https://xkcd.com/2821 as per the Artist's desires.

  Yes, I saw the explain, but that isn't to the actual origin.

  Somehow he keeps on making awesome stuff, after all these years

  Path that maximises time would be some kind of space-filling curve. Maybe it does that off panel?

    Basically, yes. The path that maximises time goes around the world, so starts by going up off the top of the screen, and re-enters at the bottom.

    Technically I think it could be a little longer by spiralling around the world several times, still reaching the target point despite going “in a straight line”. If we ignore the “straight line” restriction, which some of the other paths already do, then the sky’s the limit. Technically actually, the sky isn’t the limit, and the path could criss-cross over the whole planet first, and the air, and the whole galaxy, before reaching the destination as the last feasible space to arrive at. Personally I think that’s too complex for xkcd, if they are going for complex I’m sure they would have come up with something about paths through n-space and black-hole theory that is beyond my pay grade.

    Xkcd good ;)

    It’s to do with light paths and diffraction. The time maximising path still hast to be a valid path.

    path that maximizes time? just don’t move. at all

    source
• Jorgelino328@kbin.social ⁨1⁩ ⁨year⁩ ago

  Shouldn't the path that maximizes time have its line go through literally everywhere in the globe rather than just going around it once?

  • GrimSheeper@lemmy.world ⁨1⁩ ⁨year⁩ ago

    Yes, but by then the ice cream has melted

  Thanks for reminding me that I have completely brain dumped all of trigonometry
