    While we aren’t all the same, there’s a difference between things that require holding 8 complicated things in mind at once, and things that require a little language learning and the intelligence to solve a crossword. This is closer to the latter - like doing a crossword in Spanish. You need to know a bunch of little things, but learning them is basically all tedium and not brilliant insights. (Taking these puzzles, creating a dozen new variants, and solving all of those probably does require managing a lot of complexity. But to understand the work of others, is not so bad)

    It’s very weird to me that you’re only listing loud things children do… Like, have you ever been around a sleeping child? Do they bother you? What about in a classroom, watching a movie, or running in the distance (out of earshot)?

    Average volume of a child is higher than adults, but only by a factor of 2 or so. And their noises are interpretable, you can definitely figure out what they mean, unlike the adult noises.











  • An arithmetic miracle:

    Let’s define a sequence. We will start with 1 and 1.

    To get the next number, square the last, add 1, and divide by the second to last. a(n+1) = ( a(n)^2 +1 )/ a(n-1) So the fourth number is (2*2+1)/1 =5, while the next is (25+1)/2 = 13. The sequence is thus:

    1, 1, 2, 5, 13, 34, …

    If you keep computing (the numbers get large) you’ll see that every time we get an integer. But every step involves a division! Usually dividing things gives fractions.

    This last is called the somos sequence, and it shows up in fairly deep algebra.
