    Spoiler: there is a simple argument against the existence of such a lower bound.

    Comment #46069244

    Interesting follow-up question: What is the distance between the set of harmonic numbers and the integers? i.e. is there a lower bound on the difference between a given integer and…

    FWIW the import syntax is now part of standard JS, according to the ECMAScript 2026 specification: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... And node seems to…

    Even today it is exceedingly rare to find a still-well-conditioned bottle of wine that has the capability to have aged for 117 years or so. Most often sweet wines are capable of th…

    FWIW I was also sceptical, but just tried it from my phone network and it seems indeed blocked. Wouldn't be the first case of different ISPs using different block-lists. c.f. bs.to…

    Measure its volume by dunking it in a jug of water and compare its weight with its expected weight (depending on the density of gold). There is a famous tale of Archimedes doing ex…

    Do not underestimate the urge to procrastinate (by still doing productive things, like learning Mandarin) while pursuing a PhD. I am not sure if this will be the author's experienc…

    You can get gcc to generate the blend instruction in the example given - you just have to 'force' it to use SIMD more aggressively by, for example, using -march=native.

    I recon the general cosensus among mathematicians (as that is what counts) is that the ABC conjecture so far has _not_ been proven. Mochizuki (and his school around him) seem to be…

    I think giving any more details than his three short posts would delve too far into the specific arguments of the paper to be valuable for a wide enough audience, subtracting those…

    Unfortunately the presented method only works for the most simple linear recurrence relations. Tangentially: look up the master theorem if you're interested in at least estimating …

    Just because of the impossibility of an exact formula for the roots of a high-degree polynomial that does not rule out the possibility of figuring out, say, the distribution of roo…

    I do (I'm a mathematican). We are usually between 4 and 10 people marking an exam with anywhere between 50 and 600 participants.

    This sounds like an organisational nightmare to be honest. You'd be going through the pile of exams multiple times (at least twice) and what do you do if there are multiple mistake…

    That is definitely not true - I have an analog wrist watch (and am under 30). Also, there can be benefits to the use of analog clocks: in some circumstances they're quicker to read…

    I'd deem it useful, though unusable in practise, as GMail for example does not accept messages that contain multiple From addresses.

    To clarify, I guess you mean "Captain in the navy", equivalent to a Colonel in other branches. A captain in the army is O-3.

    The difference is that in the Schrödinger case you're effectively 'turning' the solution (in the complex plane) which leads to the uncomfortable question of whether the solution to…
