Why do I keep typing "whould" when I mean "should"?

subconcious concern that stronger language may invoke an accusation of inaccuracy?

bofh: hmm, more data needed. Are these "protesters" people who want to respond to his speech with more speech... or prevent him from speaking at all?
<soundnfury>
because, it's not like the latter kind are unheard of at the moment
<G-Mobile>
Based on the information O have access to, its not clear that the protesters are related to the guy, like that day last week when five million juggalos had a protest same day and place as fifty or sixty unspecified alt-righters
<G-Mobile>
I*
<G-Mobile>
Which is from a third person perspective funny because the juggalos were protesting the FBI classifying them as a gang, and juggalos are known among many things for promoting violence against racists
<G-Mobile>
are the earth's magnetic poles attached to specific matter? like, when the pole flips, does that represent material in the earth flipping, or is it an electrical sitation changing how current flows?
<G-Mobile>
also, are the north and south poles coaxial, and do their axes pass through any sort of centroid?
<UmbralRaptor>
The current flow one, and coaxial, but it's complicated.
<UmbralRaptor>
Essentially see multipole expansion.
<G-Mobile>
so, I've opened the wikipage for that, and I've read the first two sentences, and I'm mostly lost
<G-Mobile>
I would assume that the bearing the current generating the field is also influenced by the field, so the two poles exert a centering force that influences the fluid to force the dominant conduit path into a rough circle that is perpindicular to both magnetic poles, so the poles don't need to be coaxial but the system seeks that as a lowest energy state
<UmbralRaptor>
Qualitatively, the actual field is a complicated mess, so we use an approximation that's a sum of simpler terms. If wrote could pull off an infinite sum, it would be a perfect representation.
<G-Mobile>
that the fluid bearing the current*
* UmbralRaptor
would flee in terror from turbulent flow on that size scale. Consult with ferram4 or a geologist?
<G-Mobile>
so like, if you could god up a planet that at creation had a magnetic field where the poles were 120 degrees apart, one of two things would happen; either the poles would push eachother apart until it approached 180 degrees, or 2 new poles would develop in the neglected butt of the magnetic field; I expect the existing poles pushing eachother apart would squish that though
<G-Mobile>
btw there is so much math on this page; maybe the most math of any page I've looked through before
<G-Mobile>
there's parts of this math where one value goes three subscripts deep, with math in there, and then there's superscripts going on at the same time with their own branching tree with math
<UmbralRaptor>
Why does that include bra-ket notation? o_O
<G-Mobile>
bra-ket? is that the weird straightline ( )s at the end?
<G-Mobile>
"[bra-ket notation] can also be used to denote abstract vectors and linear functions in mathematics. In such terms the scalar product, or action of a linear function on a vector in a complex vector space, is denoted by [math]"
<G-Mobile>
I lack the capacity on this keyboard to enter 4/5ths of the characters in [math]
<UmbralRaptor>
Yeah
<UmbralRaptor>
See also the puns in egg's nicks.
<G-Mobile>
oh, so egg's in a quantum state? never knew
<UmbralRaptor>
eg: |egg> is a vector, zzz is an operator, and <egg|zzz|egg> is the expectation value.
<UmbralRaptor>
(which is near 0 because this channel is bad at sleeping.)
<G-Mobile>
nobody is worse at representing accurate states with their nick than egg
<UmbralRaptor>
Aside from sleep, they're not too inaccurate.
<UmbralRaptor>
… why did GMU send me a school related email at 0136?
<G-Mobile>
automatic?
<UmbralRaptor>
Probably.
<G-Mobile>
I would assume they can't send out tens of thousands of emails in one lump, so probably the exact timing is weird because that's where in the queue yours was
<G-Mobile>
.... would you trust a website named "selfication" to instruct you on proper breathing techniques?

if you have a volume of time, is that a kind of timespace?
* soundnfury
gives G-Mobile a timecube aaaaaaaaaaaaaa
<G-Mobile>
I wonder what it'd.... be... like to move through perpindicular temporal dimensions
<FluffyFoxeh>
what would it be like to perceive time non-linearly
<soundnfury>
time is just a thing analogous to the gradient of a gigantic-dimensional complex-valued vector field
<soundnfury>
quantum uncertainty comes from stagnation points where the gradient becomes ill-defined
oeuf has joined #kspacademia
<soundnfury>
to get a time tangent (I think it's a dual vector?) pointing in a different direction — perpendicular, if you like — you'd have to change the Schrödinger equation to walk a different way around the field
uovo has joined #kspacademia
<soundnfury>
physics would look different when treated time-dependently, but the time-independent Schrödinger equation would look the same (I think that means you'd keep the same notion of energy?)

awang: well for now principia only manages things when you get out of the atmosphere

awang: the plan would be to manage things as soon as you leave the ground

<egg>
yup
<egg>
so we have a 10-point-plan for the reunification of the ferram4 and egg sectors
<egg>
and this is the 2nd point: can't land anywhere above 300 m, but we do manage rotating frames
<awang>
They were unified in the past?
<egg>
nah
<awang>
So what's with the reunification?
<awang>
And how are you pulling this off?
<awang>
Sounds... complex, to say the least
<egg>
it's mostly a running joke that YOU ARE ENTERING THE EGG SECTOR | CARRYING WEAPONS OFF-DUTY FORBIDDEN | OBEY GRAVITY resp. when entering the ferram4 sector OBEY THE NAVIER-STOKES EQUATIONS

speaking of sun raptors, I was listening to a podcast that takes questions on a broad range of topics that can involve death; and someone asked "what would happen if the earth was flat, would we all die?" the answer "Yes, yes we would all die, as the earth became round"
