… for a channel named "academia", we have surprisingly few academics
<UmbralRaptop>
(also, I think only one person with a PhD)
<UmbralRaptop>
(not me)
<SilverFox>
who has the PhD?
<SilverFox>
and is it something worth having a PhD in?
<SilverFox>
f(x) = first line of I Want It That Way by Backstreet boys
<UmbralRaptop>
Some lepidopteran, and chemistry, so I'm not sure what their job prospects are
<SilverFox>
chemistry definitely is a decent one
<SilverFox>
lots of places to go with a chemistry degree
<SilverFox>
question real quick
<SilverFox>
how did apple fall on newton's head if gravity wasn't invented yet???
<SilverFox>
UmbralRaptop, I have a self-given PhD in shit-posting
<SilverFox>
does that count?
<UmbralRaptop>
Is SilverFox University an officially accredited institution?

[WIKIPEDIA] Signature matrix | "In mathematics, a signature matrix is a diagonal matrix whose diagonal elements are plus or minus 1, that is, any matrix of the form: A = ( ± 1..."
* egg
glares at the bot
<mofh>
egg: not offhand, also that is a very weirdly specific matrix, where is it coming up?
<egg>
mofh: from trying to flip e1 (and keeping handedness, so e3 too)
<egg>
(or trynig to flip e3)
<egg>
mofh: conteggst: rigid body rotation
<egg|zzz|egg>
mofh: also have you considered: planet trajectories drawn by Principia

egg: at that point why not just treat it as a vector?

egg|cell|egg has joined #kspacademia
<egg|zzz|egg>
mofh: my question is not one of representation (if it were, why a vector? that's still way more than there is in those three bits), but of naming
<UmbralRaptop>
B787_300: we're getting a preemptive turbulence warning
<egg|zzz|egg>
what is the name of that kind of transformation
<B787_300>
UmbralRaptop: this is the CLT-LAX leg?
<B787_300>
not suprising considering the storms
<UmbralRaptop>
yeah
<egg|zzz|egg>
!wpn mofh_

!wpn UmbralRaptop

gives UmbralRaptop a resonant CCD with a bird attachment

!wpn B787_300

gives B787_300 a moon hazard

<galois>
egg|zzz|egg: Your options: soviet republic, sleep. My choice: soviet republic
<mofh>
egg|zzz|egg: I mean my point is that purely diagonal matrices generally aren't interesting enough to have special names
<mofh>
egg|zzz|egg: also I've had a wild/hectic past few days, apologies for not being around really
<egg|zzz|egg>
mofh: well apparently there is a name, see backlog
<mofh>
let me get that whiteboard stuff to you now
<mofh>
yeah I'm legitimately surprised at that
<egg|zzz|egg>
so I guess geometry::Signature
<egg|zzz|egg>
which will be implemented as three geometry::Sign
<egg|zzz|egg>
(which I really need to change so it actually takes the sign bit instead of comparing with 0....)
<SilverFox>
how low-level can functional programming languages go?
<whitequark>
take a look at Habit (the haskell dialect)
<SilverFox>
like haskell
<egg|zzz|egg>
mlbaker: it's made of signs! clearly we can generalize this, if you have a matrix with squares on the diagonal it should be a quadrature matrix,
