      When I’m watching TV with friends I like to leave the volume at 9, 11, 17… numbers like that, and then act like they are the crazy ones if they get annoyed

        Am I the only one that doesn’t care what the volumes at? if I can hear it and it isn’t too loud idc if its even, odd or ending in 5/0

          I used to be like that, but my current setup changes the volume by a lot with only one number. 7 ish if my gf is asleep, 10 otherwise. 12+ if there’s a lot of noise elsewhere. Was annoying at first, but now I don’t care, so I guess the curse has finally been lifted

          I only care if I can hear and I consider myself fairly normal. In the car, 9 is usually where I can hear my podcasts over the road noise. 8 and I miss words. 10, and it eventually gets unpleasant. On the TV, I don’t know: I run all the audio through a tuner and it’s hard to see the numbers from the couch. Besides, I think it measures in dB, which I don’t understand. For most shows, I think it’s somewhere in the -30s.

        My phone used to increment the sound by 2 notches per clicks and that pissed me off so much I couldn’t have the one in the middle 😭

      I always pick a transcendental irrational number. If they make the mistake to only ask me for a number it’s gonna be complex. What do you mean, “is it greater than 5?”? What the hell is “great than”???

    well real numbers are uncountable, but the set of numbers you can think of and describe is still countable

        You have the explanation, but more precisely: the set of definable real numbers is countable, because a mathematical definition can be encoded as a finite sequence of mathematical symbols (of which thereare only finitely many), and so there are only countably many definitions.

        Hence most real numbers are undefinable.

        By the way, there is a simple proof that all natural numbers are definable: if not, then there is a smallest undefinable number. But “the smallest undefinable natural number” would then be a definition of that number :)

            I hoped someone would make that connection! This one is actually sound but there is a closely related limitative result, the undefinability of truth (attributed to tarski) which uses a “liar sentence” like the “liar set” of Russell’s paradox: “this sentence is not true”. Of course, liar sentence have been known since ancient times, but it was only in the 20th century when we could give them a mathematical interpretation, rather than a purely logical one.

            This means that there is no mathematical definition of what is true about the natural numbers, but there are still definitions of other things, and we can still quantify over those definitions.
