yep, it's gender zalgo, I'm just impressed at how *heavily* it's zalgo'd.
<Ellied>
whitequark: I'll absolutely believe it. what kind of symptoms does that cause, in the short and long term?
<Ellied>
truth be told I still don't actually know what radiation really does to you, beyond vague descriptions of three-dimensional sunburns
<whitequark>
radiation burn
<whitequark>
the skin gets all weird and fragile
<iximeow>
Ellied: maybe not the most related, are you familiar with anatoli burgoski's uh.. particle accelerator incident?
* UmbralRaptop
unfortunately just knows the textbook stuff. Nothing about the details of what chemical reactions occur in what parts of the cell.
<Ellied>
iximeow: vaguely.
<Ellied>
I know what happened and that he somehow survived, but not the details of his symptoms
<whitequark>
it's not actually very surprising that he survived
<whitequark>
as for symptoms, well, it's about what you'd expect for significant neural damage
<Ellied>
I'm not sure what I would expect for that
<whitequark>
fatigue, loss of sensation in an ear, tinnitus, partial face paralysis, occasional seizures
<Ellied>
alright
<Ellied>
do the effects of radiation on the body tend to differ qualitatively for heavy charged particles vs high-energy photons?
<Ellied>
I'm under the impression that it takes a different amount of each one to do the same amount of damage, but I don't know what differences there are in what type of damage they do for the same equivalent dose
<whitequark>
Ellied: definitely
<whitequark>
high-energy photons wouldn't burn a hole right through your head
<whitequark>
well
<whitequark>
ok sure they would but it'd require a shitton of x-rays
<whitequark>
let me rephrase
<whitequark>
in practice i don't think you can have an "equivalent" dose of ions and x-rays
<whitequark>
it's easy to focus ions and it's hard as hell to focus x-rays
<Ellied>
that makes sense
<Ellied>
it seems popular to always talk about 'doses' of radiation and lump all the different types together under one umbrella, but that never sat well with me since I suspected they all tended to do different things that don't compare well
<whitequark>
oh
<whitequark>
why do you think there's separate roentgens and grays
<Ellied>
so sieverts really are a "how bad" measure thats weighted according to type?
<whitequark>
yes
<Ellied>
that sort of strikes me as hard to quantify into one number like that
<whitequark>
well
<whitequark>
it's a squishy measurement
<Ellied>
fair
<Ellied>
I remember laughing nervously back when I played Kerbal Space Program and the Interstellar mod was telling me that my kerbals were getting like several megasieverts per hour or something
<whitequark>
in jool's radiation belts or what
<Ellied>
I think at that point it's not so much acute radiation syndrome as turning into plasma
<Ellied>
yeah
<Ellied>
hrm, maybe jus boiling, that'd only be in the kW/kg range assuming Wr=1
<SnoopJeDi>
wow. digital gyroscopes are *really* cool
<whitequark>
wait until you hear about fiber optic gyroscopes
<SnoopJeDi>
laser gyros are neat, sure
<SnoopJeDi>
one of our optics labs was on that, actually. Learned about Sagnac's description of a white-light interferometer, and how Michelson actually used it measure the precession of the Earth (or was it the nutation?)
<SnoopJeDi>
but jeez, MEMS is neat. I guess I missed the memo about living in the micromachine future at some point
<whitequark>
nutation
<whitequark>
fake word
<SnoopJeDi>
come again?
<Ellied>
yeah I think at least one of the Ms in MEMS stands for "magic"
<SnoopJeDi>
I assume that my electronics blindspot is just *that* big
<SnoopJeDi>
that things people accepted 20-30 years ago are probably still amazing new ideas to me
<whitequark>
SnoopJeDi: "nutation" sounds fake
<Ellied>
I've been using MEMS oscillators for my counter project, which is probably one of the most boring MEMS devices around. It's just a really tiny box (about the size of a 1206 passive SMD, but thinner) that takes a tiny amount of power and produces an incredibly accurate and stable clock signal
<whitequark>
yeah but we've had quartz crystals for a long time
<Ellied>
I mean tbf nutation was one of the harder concepts for us to grasp in classical mechanics II class, since none of us had really ever seen it in action in real life and the math was pretty dense
<Ellied>
we have. I'd been fiddling around with making my own CMOS oscillator using a big metal can quartz crystal and didn't get super good results compared to the all-in-one MEMS package
<SnoopJeDi>
whitequark, I'm always tempted to misread it as nutrition
<SnoopJeDi>
(which *is* fake, heyoooo)
<SnoopJeDi>
oh incidentally whitequark since you're active...have your animal readings ever brought you across mycoplasma in rats?
<whitequark>
nope
<whitequark>
what gives
<SnoopJeDi>
one of my girls was really sneezy the other day and I 100% panicked and took her to the vet, worried that I'm an idiot and can't hear fluid in her lungs right and I'd missed it for months
<SnoopJeDi>
vet gave her a physical, said she heard nothing and she's fine
<SnoopJeDi>
but I'm also cognizant that not every vet is going to be intimately familiar with the particulars of every kind of exotic, so it's in my interest to be an informed caretaker
<SnoopJeDi>
seems like you collect animal physiology stuff pretty readily, so figured I'd ask while it was opportune to do so
<kmath>
<whitequark> I found it. I found the most optimistic line in any bus specification ever [from the I2C spec] https://t.co/Britzusk6G
<Sarbian>
egg|anbo|egg: ok, nothing to worry about. They added a reverseoffset property to FloatingOrigin that is just -refPos with a default value when Floating Origin is not active
<Sarbian>
And it s used in the PQS
<egg|anbo|egg>
Sarbian: ok, thanks
<egg|anbo|egg>
Sarbian: have they done anything to the ~ladder force~?
<Sarbian>
No change in the module that I can see
