        Well, “hairs” are quantized phenomenon…

        So at some finite time, it will be all gone. At least if the thing is happening fast enough for it not to grow back at a similar time-frame.

          Kinda. At the last strand I expect them to switch to length.

          But yeah, at some point should be good enough

            But hair is still made up of discrete quantity of “stuff”

            Well, eventually you get to a point where hairs grow quickly enough that the haircuts effectively stop. I think the sum total of hair material you trend towards at the limit would be the sum of length of hair that grows during the time it takes to do a haircut. Whether it’s 1x or 2x of the hair growth amount depends on whether you measure at the start, or end, of the haircut

    When I was a kid I encountered this problem when I wondered what would happen if I half-empty a bottle of soda, re-fill it with water, and repeat. Will it eventually become just water or will there always be some soda left? It boggled my mind for a while, then I forgot about it until I reached university calculus haha

      • You mean less steps. True homeopathy dilutes until there’s no measurable amount of the substance left; it’s just pure sugar/water/alcohol. You’re supposedly getting benefits from “the vibrations.”

        Of all the pseudo-science quackery, homeopathy is one of the most idiot-prone.

          No, I do mean more steps, because homeopathy dilutes a smaller volume of target material, they actually would perform fewer steps than dilution via halving.

          • Homeopathy often dilutes by taking far less than half of a solution and diluting it in a large amount of fresh solvent. One process repeatability empties the entire container and refills it with solvent.

            If you were diluting something by replacing only half with solvent, you’d have to do many more steps to get as pure solvent as homeopathy produces.

            Homeopathy is a tremendously wasteful way of washing a container. It’s hugely wasteful, and being a homeopathic environmentalist is oxymoronic.

    Well there’s a discrete number of hairs on that rodent thing, depending how the barber rounds they’ll have to cut the last hair eventually. Unless they only cut half of the last hair?

      … then they cut one half of the remaining half.

          Finite number of atoms as well, and yet scientists can split those too.

            At this point you’re splitting hairs… wait…

            I mean technically there isn’t a finite number of atoms because there isn’t a finite number of anything because everything is part of the same energy field with varied energy states caught in self reinforcing patterns and when you “split” an atom you simply break the pattern allowing rapid entropy to a stable state.

            Tldr: the solution to this paradox is that it is impossible to split anything in half, you can only rearrange it.

        If you sum the hair removed from one lil guy you’ll get 1. If you sum the hair removed from all lil guys you’ll get the amount of lil guys.

        But yeah, you’re right. I think they’re looking at the problem differently. We don’t care about how much hair it has at each step. It can’t gain hair from a hair cut.

    it took me a while to understand that the guinea pig(?) in the window is meant to be the reflection of the one outside. Because the surface is roughly parallel with the viewer, the one outside is pointing to the left, so the flipped pig should also be pointing left.
