<raptop> Please keep it safe from accelerators
<SnoopJeDi> no one is safe from accelerators
<SnoopJeDi> it's weird how little accelerator-on-chip stuff there is in speculative fiction come to think of it
<raptop> Hrm, the last speculative fiction story I can remember involving accelerators had people going back in time and sabotoging the SSC to prevent an invasion by aliens from other dimensions
<SnoopJeDi> 👀
<SnoopJeDi> which story was this?
<raptop> urgh, can't remember. It would be a novel published somewhere around 1995 or 1996, I think?
<SnoopJeDi> probably enough to search on
<raptop> But yeah, accelerators of a certain capability can make wormholes (sort of), first contact happens (with 2 different sets of aliens, one friendly and one hostile)
<SnoopJeDi> I would like to state for the record that "supercollider aliens wormhole time travel" is in fact a very noisy search; I had not accounted for nutters and bad popsci
<raptop> hah
<galois> title: About Einstein's Bridge
<raptop> Sounds like the right name
<SnoopJeDi> clever name, too
<raptop> Yeah, that's the novel

<egg|laptop|egg> whitequark: how does pluralization work for negative numbers in ru, is it on the absolute value?
<whitequark> i've never thought about it
<whitequark> рь
<whitequark> *hm
<whitequark> yeah
<egg|laptop|egg> OK
<whitequark> grammatically "минус" is just like a prefix
<egg|laptop|egg> seems CLDR semi-implicitly assumes it is on the absolute value in all languages, I have yet to find a countereggsample but this vaguely surprised me
<whitequark> aren't negative numbers generally younger than languages?
<whitequark> as in
<whitequark> they weren't used for long enough to be treated specially
<egg|laptop|egg> well, depending on how they are worded they could do grammatically different things
<egg|laptop|egg> I could imagine a language wherein -1 is read as одна whatever
<egg|laptop|egg> whitequark: consider how in French n! is read as "factorielle n" whereas in English it is "n factorial"
<whitequark> wait
<whitequark> whether it's один or одна depends on the countable noun
<egg|laptop|egg> okay that was a bad eggsample
<egg|laptop|egg> but I mean, it could be read postfix
<egg|laptop|egg> or it could be read in some other way that changes the grammatical class of the whole
<whitequark> hrm
<whitequark> yeah i see
<egg|laptop|egg> whitequark: after all it is not more grammatically obvious that (-1) cat(s) should be pluralized on the 1 anymore than (cos 1) cat(s) should be
<whitequark> uhhh
<whitequark> i don't think "(cos 1) cats" has a valid russian syntax tree
<whitequark> like, i don't think you can write it out in words in a way that makes sense
<whitequark> this is because "cat(s)" has the role of a measurement unit here and you don't normally take trig functions of those
<egg|laptop|egg> what about sqrt(2) km?
<whitequark> корень из двух километров?
<whitequark> completely ambiguous and sounds horrible
<egg|laptop|egg> :D :D :D
<whitequark> i imagine any actual use would write it symbolically
<whitequark> or just use a decimal expansions
<whitequark> *expansion
<egg|laptop|egg> probably yeah.
<egg|laptop|egg> whitequark: also what about 10^11 km
<egg|laptop|egg> (or 10^2 vs. 10^5)
<whitequark> hm
<whitequark> десять в одиннадцатой [степени is implied] километров
<whitequark> is how i'd say it
<egg|laptop|egg> oh, interesting
<egg|laptop|egg> in french you have the construct "dix puissance <exponent>" which makes it slightly odd because the exponent is trailing
<egg|laptop|egg> so it kinda feels like it almost wants to pluralize on the exponent but I have no idea
<egg|laptop|egg> then again this is only relevant if the absolute value of the exponent is either 1 or a multiple of one million
<egg|laptop|egg> whitequark: yes, french (like other romance languages) has three plural cases, 1, multiples of one million, and anything else :-p
<whitequark> hm
<egg|laptop|egg> (you need a preposition with multiples of a million, "one million of something", a bit like the genitives in ru)
<whitequark> right okay
