<egg|work|egg> bofh: thinking back on that templatized approximate rootn question, it seems like a fun idea to have couple-of-sig-dec-correct, fistful-of-ULPs-errors, correctly-rounded, and exact versions of a bunch of things...
<egg|work|egg> Principia has an exact product and an exact sum atm
<egg|work|egg> why have one libm when you can have four
<bofh> most of my libm-and-similar experience is in writing fistful-of-ULPs-errors code, b/c it is *hard* writing correctly-rounded Bessel functions of arbitrary order, even in the integer case.
<egg|work|egg> bofh: right, but there is also a use case for the "rough approximation" version
<egg|work|egg> (e.g. the stepsize adjustment of 0.9 * nth root of error estimate)
<bofh> True, but oftentimes it suffices to inline like a truncated Taylor series in that case.
<egg|work|egg> bofh: that seems a bit less readable than a dedicated function though
<egg|work|egg> bofh: also why are there no search results for "a fistful of ULPs",
<bofh> ...I'm surprised, that's a very good turn-of-phrase. Clearly we need to fix this. :P

<Qboid> UmbralRaptop: Adjective added!
<egg|zzz|egg> <SnoopJeDi> god I hope my advisor does not ever discover this paper <<< why?
<SnoopJeDi> because he might like it
<SnoopJeDi> the central motivation of the paper is basically identical to his: we have no sensible target energy scale beyond Higgs
<SnoopJeDi> soooooo, go big or go home
<bofh> SnoopJeDi: who says we'd find anything interesting even once we hit the Higgs energy scale, tho?
<SnoopJeDi> This guy just out-crazied him by a remarkable margin
<SnoopJeDi> bofh, well we've been past Higgs for decades, but...yea, that's basically the point
<SnoopJeDi> most of the issues with Higgs detection weren't about production, we've surely been creating them since at *least* the Tevatron
<SnoopJeDi> I mean I'm not a HEP guy but the perspective I have looking out is that people are looking to put dressing on building things like FCC after the fact
<SnoopJeDi> and LHC was sufficiently expensive that this seems like a terrible idea
<SnoopJeDi> (that said, LHC is a smashing success and there is a lot of great science being done there)
<bofh> (indeed!)
<SnoopJeDi> albeit very little of it depends on reaching very high energies :P
<SnoopJeDi> if the West builds anything of Very Big Project scale in the next 20-30 years, it's going to be an EIC imo.
<SnoopJeDi> um unless you count upgrades like HL-LHC I guess?
<UmbralRaptop> EIC?
<SnoopJeDi> hm, I thought I'd added that one. Electron-ion collider: https://arxiv.org/abs/1212.1701
<SnoopJeDi> NSAC made it priority uhh number 4 I think in the most recent long-range plan, after finishing FRIB (lol), continuing to operate CEBAF @ 12 GeV, and a ton-scale neutrinoless double-β decay. So basically the top of the list.
<UmbralRaptop> !acr -add:EIC Electron-Ion Collider
<Qboid> UmbralRaptop: I added the explanation for this acronym.
<SnoopJeDi> There's FCC but see above re: there's no reason to believe 100 TeV is special
<awang> UmbralRaptop: pretty much all the Twitter things
<SnoopJeDi> Maybe somebody will make a Higgs factory?
<awang> And past-freshman-undergrad things
* UmbralRaptop keeps on reading FCC as Face-Centered Cubic.
<SnoopJeDi> seems likely that China will build something
<SnoopJeDi> enough of a chip on their shoulder and a low build-up of bureaucratic bullshit around their accelerator programs
<SnoopJeDi> low(er) anyway
<SnoopJeDi> ...none of which addresses the problems of the sophons :)
