great, guess we continue here

random

[tribal rose]

Thanks I never really understood the threads, I'm intelligently unintelligent lol, but anyways

[bold cape]

like, a true, matured "AI", like actual "human-being AI" - will need at least 4 century (way pass our lifetime) to complete. (don't quote me on this)
Or, at least we human had been completely researched how human brain worked.
"human-being AI" is still a software/hardware simulating "how human brain work" in the end of the day.
What we currently have right now is a software/hardware simulating:

• how a "perfect human" will be react to certain action (gameplay ai? tas bot?)
• how a "perfect employee" will do with certain job (warehouse bot?)
  etc etc, u got the idea

[tribal rose]

Agree but I don't see they need to be human-like but better then humans, because to be truly human for my understanding is basically have good and bad of our human nature then added to ai format could be a problem, that's why think true ai needs be similar to human but different but also different in better way.

I believe merging AI into humans could be one next step to human evolution and not just ai add but while a whole suite of upgrades, both cybernetics and genetically. Just as AI and technology have great potential but I believe so do improving the biology of the human body, that's why if humans improve our biology with cybernetic and ai stuff, combined I think has even higher potential then sperate

For example, if we can improve the size of humans to be smaller or bigger body frame have their own benefits, but let's use bigger for example. Let's say the human body is ten feet tall, One idea was adding two things first is an aluminum powder fuel reactor or something like that is small and that doesn't damage itself or humans providing power to all cybernetics from energy it produce plus it's flammable, it only needs water and aluminum supplements, biologically turn human body into having photosynthesis like effects improving body's need for substance only needs materials to make sugar and other material for flesh

Talking about ai and human combination in the brain, ai could help humans organize their knowledge and anything they learn to organize files then feed it to persons consciousness when needed, it helps with calculations, but also parental help, such as keeping kids from going to lewd websites till of age, help manage their schedules and finances and more, diagnosing mental and physical problems, or such a as child abuse and neglect. Record and present evidence to police or lawyers and more though their probably problems with such things but it takes time to take out the kinks

I am on a quest to discover every secret nook still open on this server. Haven't found many, but ill call this one Bob.

Hello

[pulsar ruin]

this is a nice secret corner cuz its literally named random

[pulsar ruin]

how would I decide what transformations to use here? like i know how to get the jacobian and i know how to evaluate once i have the bounds and all but finding out what transformations to use and how to get the exact bounds from them i am struggling with

@normal viper i summon you

[normal viper]

WHAT

[pulsar ruin]

hi

what you thought i was kidding with random secret channels

[normal viper]

i probably have to mention this to someone

[pulsar ruin]

nah

[normal viper]

but ill at least answer your question first

[pulsar ruin]

pretty sure heir knows abt this and vani reasonably could

[normal viper]

idk this is annoying to do with change of variable

i already said how id solve it right

[pulsar ruin]

ikr

preeeetty sure the goal is to make it into a rectangle

[normal viper]

let me think for a moment

[pulsar ruin]

[normal viper]

it is quite annoying

two of the bounding functions are parabolic in x

and two are reciprocal

[pulsar ruin]

i graphed it so like i can visually see how id do it w/o cob

but alas

[normal viper]

your graph is nicer than mine

[pulsar ruin]

[normal viper]

thanks for the sanity check tho

[pulsar ruin]

[normal viper]

yeah i mean without cov

you write a piecewise function for the height between enclosing segments

with 3 piecewise segments, between each set of line intersections

then you integrate across that piecewise function for area

and integrate over that area for the actual function value (8x)

or something like that

[pulsar ruin]

wait, only two would technically be needed, right?

cuz from 0.5 to 1 then 1 to 2

[normal viper]

oh ya

two of the intercepts are on 1

you're correct

[pulsar ruin]

man, itd be so easy...

[normal viper]

i wonder if the correct transform is log

can you give that a shot

[pulsar ruin]

surely not...

[normal viper]

it comes to mind for this kind of problem

[pulsar ruin]

i guess

[normal viper]

turns exponents into coefficients

which is nice

[pulsar ruin]

hmmmm i mean i suppose yea true

[normal viper]

it also integrates nicely

yeah try ln

well its not really a rectangle

idk if its any better

[pulsar ruin]

yea thats what i was getting... like its different but not a rectangle

i feel like we overcomplicatin smthn

i could go to the answer key but like thatll prob just say "ah yes lets use this transformation" but not explain why which is what im tryin to learn lol

wait

we have y=x^2 and y=8x^2 (aka 1=y/x^2 and 8=y/x^2) and then xy=1 and xy=8

[normal viper]

classic

[pulsar ruin]

so then we can do u=y/x^2 and v=xy then we have 1≤u≤8 and 1≤v≤8

cuz like we want to get constants on one side if we makin a line

the 11 PM brainwave

[normal viper]

you never use this again after that class btw

math major certified

it may show up in proofs but the steps will be clearly explained and you won't be expected to reproduce them

[pulsar ruin]

yea i dont expect to need it past this... but at the same time i do need it FOR this

[pulsar ruin]

and also the answer key did use this

also the person that created this thread was last active here 1/26/2023

[normal viper]

they forgot the jacobian and were never heard from again

[pulsar ruin]

i hope i dont forget the jacobian. i think i will remember

i mean its just determinant of a matrix of derivatives so not too hard to remember

and not too hard to execute with a CAS calculcator

[normal viper]

i always mix up the order of the off-diagonal entries in the matrix

CAS calculator wtf

you get calculators during your exams?

literally free

[pulsar ruin]

you have to show ur work very step by step

ya cant really skip any steps with it

[normal viper]

yeah calculators are just banned from all of my exams

full stop

my midterm today? no calculator

[pulsar ruin]

o7

[normal viper]

gram schmidt process with no calculator i hope i didnt mess up

so many square roots

[pulsar ruin]

ngl i check syllabi before classes whenever i can to find the prof with the loosest calc policy cuz like im not goin into pure math im goin into engineering, im never not gonna have a computer to quadruple check my math

[normal viper]

i dont do that lol, no profs here have loose calc policies

its almost certainly a department policy

[pulsar ruin]

i dont want to pull a mars climate orbiter om

[pulsar ruin]

rip

[normal viper]

when you are allowed calcs, the university sells specially-marked calculators with a known feature set and only those are allowed

so there's no loopholes

[pulsar ruin]

yea for my classes its basically been a nonverbal "go ahead and cheat. youll suffer in the next classes if you do."

[normal viper]

but if every class says that then it's false

[pulsar ruin]

i mean if ya dont know what ur doin on a problem like this you cant just type it into a calculator

ya gotta know what you are doin to type it in

[normal viper]

true enough

but for kinematics stuff at least you can almost always re-derive the formulae from intuition

i could probably solve that question above if i was familiar with the terminology

but i never encountered shear force

and moment i only encountered w.r.t. moment of inertia

reminds me of the buckingham pi theorem

[pulsar ruin]

shear force is the force at a point shearing it, and moment is the like bend like in this direction ↩️

[normal viper]

my intuition says the equations all look like torque but weird

just gonna be some ripoff of r*F

[pulsar ruin]

i mean the equilibrium formulae are all you really need, but yes that is moment

well

[normal viper]

lever action everywhere

[pulsar ruin]

the equilibrium formulae includes the moment equilibrium formula so the "but" is not quite accurate terminology

but yea

levers be levering

also ive written like probably 50 programs total for my classes this semester, with some being like 2 or 3 lines and other being like 150

[normal viper]

ive mostly written proofs

[pulsar ruin]

i forgot to save and lost 2 big ones

here's one of my longer ones:

Define secdrvtst2(f)=

:EndPrgm

[normal viper]

i dont know what language that is but i hate it now

[pulsar ruin]

also this was written mostly on the small keyboard of this- i mean some bits were from a menu but yk

[pulsar ruin]

TI-BASIC

[normal viper]

calculator programs

i wish i could press a button and run some algorithm instantly

[pulsar ruin]

ive just realized i have like 4 years of experience with TI-BASIC 💀

[normal viper]

im expected to do stuff like this by hand

[pulsar ruin]

oh also the missing chars in the code block are math things

[pulsar ruin]

i hated linear algebra cuz it was just so many steps

i love that i can just straight up have the math in my programs tho

[normal viper]

no salvation for me

only pain

[pulsar ruin]

i mean there's wolfram mathematica with i think you can do similar stuff with

[pulsar ruin]

im glad this channel finally lived up to the prophesized math nerd invasion :)
and how it just became basically a DM but like... in neurocord

but yea this whole convo was helpful, i feel more prepared for my exam

[pulsar ruin]

shiro

i did not do good

i havent gotten a grade back but like

i know for a fact i flopped that HARD

like i flopped so hard the music from this was playing in my head

https://tenor.com/view/there's-nothing-we-can-do-gif-15878626962415498830

[pulsar ruin]

i didnt forget the jacobian- but i hit a brick wall on actually executing a lot of other stuff, so i think i bombed that exam ngl

[pulsar ruin]

we be

[silent juniper]

I won't even try to understand these spells

[normal viper]

oh well I bomb things all the time

it is what it is

I remember being annihilated on a physics exam by a stupid charged ring question

still get nightmares of it

[pulsar ruin]

i did bad on my 1st physics exam this semester cuz of a charged sphere question

[normal viper]

[pulsar ruin]

i know.

this is what killed me

[orchid temple]

[pulsar ruin]

Just got my Calc exam back. I very much did flop it.

[normal viper]

condolences

Jacobian?

[pulsar ruin]

I’m in class rn so I haven’t really looked at what it all was cuz focused on making sure I don’t get behind on the new content

lol

[pulsar ruin]

@normal viper everyone, everywhere

[silent juniper]

[normal viper]

[silent juniper]

[pulsar ruin]

[orchid temple]

ThreeDimentionalNeurosamaSoCute

[pulsar ruin]

I just got an email
An invitation for an interview
As a follow up to my MIT application

[silent juniper]

[pulsar ruin]

(Ignore that this is forwarded, totally not asking for help from a few other nerds)

[normal viper]

well the contact area will be proportional 3/4 of the wheel's circumference

since the mass of wheel and the contact area both scale linearly with the width of the wheel, I think that component cancels when solving wrt velocity

[pulsar ruin]

I did end up getting it done lol, went to the TA office hours

[normal viper]

then you just set stuff equal and solve

[normal viper]

oh ok lol

sorry I'm late

[pulsar ruin]

U good u good

Also

[pulsar ruin]

#1439849998446628925 message indeed it do

@bronze skiff

Like the adjugate and stuff really threw me for a loop at first

[bronze skiff]

Yeah that's our next subject, gonna be in the final exam

A little worried about that

[pulsar ruin]

Ah, yea, understandable

The adjugate was especially hard for me cuz like it’s just so many steps where if you mess up one bit GG

[bronze skiff]

Yeah I tried to do couple of them like yesterday just so I know what's coming up and first it felt surprisingly simple but then I started actually writing them and uuhhhh yeah

[pulsar ruin]

Yea it do be like that

Are you allowed calculator or no

[bronze skiff]

a classic physical one yes

in the final exam

but this one I just had, no

[pulsar ruin]

Ah

Yea I wouldn’t have passed if I wasn’t allowed calculator cuz like

I’d make a few small algebra mistakes or smthn

And it’d be all over

[bronze skiff]

exactly

[pulsar ruin]

I mean I still made a few and it was bad but like not fail bad

[bronze skiff]

Yeah I had to multiply two matrices in my head and I was not enjoying it at all

[pulsar ruin]

Ohhhhh noooooooo

I love matrices as data structures (like in MATLAB and stuff) but actual matrix math I struggle with lol

[bronze skiff]

yeah and not even like 2x2, it was a 4x4 so like half way through I realized I messed up and had to start over

[pulsar ruin]

Oh noes

[bronze skiff]

Matlab would be nice if I actually learned it properly

[pulsar ruin]

NGL MATLAB is super easy to learn, the biggest downside is that yk, it costs money

Like if you don’t know how to use a command, you literally just go in the terminal and do /help [command name]

[bronze skiff]

Thank god my uni pays for the license

[pulsar ruin]

Yea my college’s engineering department isn’t big enough to have got an institutional license sadly

[bronze skiff]

Ye the problem with me is that I would learn it if I had time, I'm like 10 weeks behind in physics rn so I'm kinda thin on time

[pulsar ruin]

Real

I mean actually I think I did pretty well on my physics exam yesterday, but I mean idk for sure cuz it isn’t graded yet lol

[bronze skiff]

Ye I failed my first one so I have to redo it in like a week (own fault, we could make a cheat sheet with 15 equations but I forgot to make one)

[pulsar ruin]

Oof

[bronze skiff]

And then like 2 weeks from that I have the one from my current period

[pulsar ruin]

Welp i gtg now, ttyl

[pulsar ruin]

o7

[bronze skiff]

cya

[normal viper]

I love the determinant-adjoint inverse theorem

it was how I calculated matrix inverses in my custom 3D engine

I found it kept precision much more reliably than trying to row reduce via gauss-jordan

[pulsar ruin]

i think it went pretty well- the person interviewing me was an alumni volunteer so they don't have a direct say in the admissions decision, but I am confident what they relay to admissions will be positive. They definitely seemed very positive on my chances of getting in- even saying when you get your acceptance, not if.
