Hm~ I'm not sure what exactly workplace caring about something means (majority of employees caring about it? employees being rewarded for it? something else?). Roughly which (nonacademic?) workplaces would you expect to care about learning true things in the way you mean?
Disclaimer: quarter-baked
Roughly half of primary school students have some experience with the concept of braids and maybe with the practice of making them. At the same time braids are nice objects to study, because they form a noncommutative group with infinite order elements.
So, would it be possible to pose some interesting-but-approachable problems about braids[1] to primary school kids? Obvious ideas for me are:
- how can we describe a braid?
- do two braid descriptions describe the same braid? what does this even mean? this can naturally introduce a concept of "invariants" (in the sense of a function from a braid representation that is equal for all representations of the same braid) and the concept of transformations of descriptions (and then maybe completeness of that)
- is every braid a commutator of two braids? (sadly this doesn't seem very natural here),
- what generator sets are there? is it sufficient to flip adjacent strands only?
[1] morally similar to "how many isometries does a cube have?"
I'm afraid of having single statisticians in random places in an organization due to incentives: I don't know how to prevent them from being pushed into finding arguments for a preselected conclusion.
It's IMO even worse with logic ("these two things are similar enough so that we can call them equivalent, no?").

Wisset ihr, wie Verspätungen aufgrund Suizidversuche erklärt werden? Ich würde überrascht sein, wenn diese auch so direkt beschrieben würden.
Silly me, obviously for any larger exponent the thing diverges and for any smaller it converges to constant 0 (at least pointwise). It's sufficient to look at stddev of position at some fixed time.
@b0rk Does `git log -1 --oneline $COMMIT` do something that's close enough?
What do you mean by "corresponds to"? That it's the tip of that branch/tag/..., or that it's somewhere in that branch's/tag's/... parent closure?
TIL that the sequence of increasingly finegrained random walks that converges to Wiener process has walks that increase their speed as they get finer (speed grows with square root of scale). Post factum it seems kinda obvious: you'd otherwise converge to a constant function. I haven't yet figured out how this changes as one adjusts the exponent.
There are a few cases that I can think of of such decisions affecting more powerful people, but in a way that's less important for them (e.g. credit scores).
An interesting case is the US college admissions system and the history of its reliance on SAT/ACT scores. IIUC its reliance on SAT (or any kind of standardized testing) decreased over time in the last decade+, but I can't find any good overview sources on this.
Then Japan didn't really acquire the writing system from China. The grammar is iiuc very different, and at some points in history characters were imported for the pronunciation, ignoring their meaning.

Huh? Isn't that the case with all languages that use Latin alphabet but aren't romance?
Why this thing in particular? This seems to be a question of compatibility between bottom bracket and crank arms (potentially including the chainrings) only. Are the compatibility questions that involve e.g. the frame on one side in a better position?
I think this isn't true without some additional qualification? After all, all petty crime, vandalism, littering, aimless churlishness etc. is against social norms. I think I get what you mean though, but am also missing a term for that kind of social norm contravening.
My vague recollection is that there was oneish root of ideograms, but the languages evolved before writing in an unrelated way. I don't know how much adoption of writing affected the languages.
@freemo Roots of the language and of the writing system are not necessarily the same. There were multiple instances of significant import of "characters" from ~Chinese into Japanese and I had the impression that at least some of them didn't import much past the characters themselves.
@dunkelstern Wie hast du rundum das Loch ohne eingebaute Dose (das linkeste) gespachtelt?
I enjoy things around information theory (and data compression), complexity theory (and cryptography), read hard scifi, currently work on weird ML (we'll see how it goes), am somewhat literal minded and have approximate knowledge of random things. I like when statements have truth values, and when things can be described simply (which is not exactly the same as shortly) and yet have interesting properties.
I live in the largest city of Switzerland (and yet have cow and sheep pastures and a swimmable lake within a few hundred meters of my place :)). I speak Polish, English, German, and can understand simple Swiss German and French.
If in doubt, please err on the side of being direct with me. I very much appreciate when people tell me that I'm being inaccurate. I think that satisfying people's curiosity is the most important thing I could be doing (and usually enjoy doing it). I am normally terse in my writing and would appreciate requests to verbosify.
I appreciate it if my grammar or style is corrected (in any of the languages I use here).
