    Counterpoint, I don't particularly have that expectation

    And then there's G. H. Hardy, famous number theorist, who wrote an "Apology" for mathematics in the sense of defending the study of number theory for its own sake because it's beau…

    There's eg https://summit.sfu.ca/item/11130 from a Tamara Smyth and Frederick Scott; Google scholar shows some citations but not necessarily conical brass in particular. That link …

    I have no idea, but I wouldn't expect so unless it was by coincidence? Not sure what chords have to do with any of this. There's a canonical way to choose 4 points uniformly and in…

    Right, I was taking it as given that the problem of choosing a hemisphere canonically for a point meant "such that the argument works in the same way as for the circle". Bertrand p…

    Great argument. I found this generalization to higher dimension: https://www.mathpages.com/home/kmath327/kmath327.htm

    I remember being very taken with this story when I first read it, and it's striking how obsolete it reads now. At the time it was written, "simulated humans" seemed a fantastical s…

    They don't appear to care about the images of the immersions or their complements, aside from them not being related by an isometry of R^3. They're not doing any topology with the …

    Comment #46784654

    To be precise, the mean curvature and metric are the same but the immersions are different (they're not related by an isometry of the ambient space). Topologically they're the same…

    yeah I have, but I think only when it gets stuck in a loop and outputs a (for example) array that goes on forever. a truncated array is obviously not valid JSON. but it'd be hard t…

    Can anyone explain (or link) what they mean by "injection", at a level of explanation that discusses what layers they're modifying, at which token position, and when? Are they modi…

    Oh now I understand. I thought your ab and ba were single tokens (even though that doesn't make sense in context). Once you point out they're separate tokens, I follow you. Thank y…

    Why do you think the constrained percentages are 0/75/25 and not eg 0/66/33? (ie same relative likelihood for valid outputs)

    You know, it only just now occurs to me to wonder if the blackjack story is the public sanitized version of "how I got $24k because I'm not allowed to tell you the real version"

    Sorry to actually your actually, but the derivative of a function f from a space A to a space B at the point a is a linear function Df_a from the tangent space of A at a to the tan…
