  • As one of the few folks who have asked such questions, I obviously am against. I don’t think the dedicated pol communities are particularly good for honest questions about platforms/political figures; everything in those spaces feels like it’s being intentionally spun (even in discussions) in a way that this community does not. (Also, several of the communities you suggest as pol discussion places are… just not? Extremely few questions, most the posts are headlines, discussions don’t seem to happen much. Some feel closer to a curated feed of cringe.)

    I do agree it could become an issue, and that would justify some division, perhaps tags? But I don’t think it is currently very unpleasant, and it will almost certainly get better in 2 months (at least short term).

    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.



  • For the uninitiated, the monty Hall problem is a good one.

    Start with 3 closed doors, and an announcer who knows what’s behind each. The announcer says that behind 2 of the doors is a goat, and behind the third door is a car student debt relief, but doesn’t tell you which door leads to which. They then let you pick a door, and you will get what’s behind the door. Before you open it, they open a different door than your choice and reveal a goat. Then the announcer says you are allowed to change your choice.

    So should you switch?

    The answer turns out to be yes. 2/3rds of the time you are better off switching. But even famous mathematicians didn’t believe it at first.
