So 18.8 * 10^k/constant stuff

okay so lemme think a bit

[vernal token]

My book made this table

d in mm: 4.0 3.0 2.0 1.0
Q in μC: 4.4 5.7 8.7 17.4
Q * d in 10^-9 Cm: 17.6 17.1 17.4 17.4

And said that through halving we get Q * d = 17.4

I'm not really sure what is meant by halving

Maybe actually the table isn't even for this exercise? They had to show Q * d is constant which they did

[split pawn]

"Halving"

[vernal token]

So maybe when they say halving they dont use the table

[split pawn]

Are you translating it?

[vernal token]

Yes. "Mittelung"

[split pawn]

Ohoh.

Translations often

give

idk

like

Not the best approach using translations

[split pawn]

ohoh

I cant think of a more elegant way

I mean

My mind wandered into averages... like function averages

But thats complicated

[vernal token]

My teacher said something about linear functions

Lines

[split pawn]

,w 2.5*(17.4+8.7+5.7+4.4)/4

Well this function isn't linear atleast

I mean I thought of it

For a linear function, the rate of change is just the slope

[vernal token]

Hm.. Halving

Maybe they took the extreme values? (17.6 + 17.1)/2? Though that's 17.35

And maybe rounded to 17.4?

[split pawn]

Okay wait

Well theres a way to turn it into a linear function

And that is by introducing capacitance

Well wait

Umh yeah

Doesn't matter lol

but

It's more like saying t

that

Okay lemme actually try it firrs

@vernal token

HEHEHEE

[vernal token]

Ok but that's not 17.4 lol

[split pawn]

I mean

Come on

[vernal token]

They took 17.4 for some reason

But that's pretty good

[split pawn]

Wait what's the round off significant figures rules again

Hol up

yeah well

idk

I mean this is what I could do with linear functions

$(x)\cdot \epsilon_r =\frac{Q}{A\cdot U\cdot \epsilon_0}$ where $x=\frac1d$

[vernal token]

Hm, I think they mean something more straightforward..

[split pawn]

Let $y=Q$, $x=\frac1d$, $$x\cdot \varepsilon_r=\frac{y}{A\cdot U\cdot\varepsilon_0}$$ $$x\left(A\cdot U\epsilon_0\cdot \epsilon_r\right)=y$$

Okay wait lol

[split pawn]

oh no

i hate it already

I didnt realise there was more to the slope

[little vine]

Is this tiktok worthy

One semi egregious mistake I need to smooth over i think

[vernal token]

Oh

I found a similar one

So they drew in a line with those values

But where did they get Q = 51 *10^-9 from?

[turbid ocean]

Oh they want you to find the closes fit i think

Thats the line of closest fit or whatever it's called

Its the best linear approximation of those points

[vernal token]

Well but how'd you draw that in

[turbid ocean]

https://en.m.wikipedia.org/wiki/Line_fitting

[vernal token]

Just by feeling?

[vernal token]

Because we never had that

I guess yeah just by feeling then

[turbid ocean]

We'll yeah ig

If you've never learnt it

Just guess it

[vernal token]

I rather take the average then

But my teacher says this is more elegant..

[turbid ocean]

That seems like a guessable line tbh

[turbid ocean]

Well that's the method used to predict values in many places in statistics

So, its the most real-life like method

Idk about elegance

[vernal token]

Ok but this is still not the way my book did it, haven't found that one out yet.

They had this table

And somehow got 17.4

As the average

By "halving"

[turbid ocean]

No clue what method your book used

[vernal token]

Ah, maybe ((17.6 + 17.1)/2 + (17.4 + 17.4)/2)/2

?

Lol

[turbid ocean]

[turbid ocean]

Ooo so close

[vernal token]

Ig you could say 17.4 from that

[turbid ocean]

By the way

[vernal token]

since this is physics

[turbid ocean]

Thats just the average lol

[vernal token]

yeah I know

The same as adding and /4

[turbid ocean]

Oh you are trying to make it a average by halving

[vernal token]

They said "halving" so maybe they still did it like this, lol

[turbid ocean]

But you won't be able to do the halving method you proposed if you had 5 values

And I'm guessing when they use the world "halving" it's some general method

So we should be able to find the average by this "halving" method for 5 values also

[vernal token]

true

[turbid ocean]

Again you should go to the physics server and ask someone who knows about experimental physics

[vernal token]

Ah wait, nvm

[vernal token]

The physics server is a bit dead

[turbid ocean]

Doesn't hurt to ask there though imo

[vernal token]

Oh, hellothere is writing

Let's hope he'll answer this one

[neat lintel]

Nvm

[vernal token]

Ah, though I assume they'd use something more straightforward than binomial coefficients, lol

[turbid ocean]

If there's a statistics discord you should go ask there too xD

I Wonder how springing with life that one would be

Also ask your teacher what halving is

[neat lintel]

I thought they meant halving as $\frac{\frac{a_0 + a_1}{2} + \frac{a_1 + a_2}{2}}{2} = \frac{a_0 + 2a_1 + a_2}{2^2}$

And you can generalise and show that the coefficients in the numerator correspond to the kth row of Pascal's triangle where k is the power of 2 in the denominator

[vernal token]

Actually, I think they just mean taking the average

[turbid ocean]

But that gave us 17.375 no?

[vernal token]

"Mittelung", that could mean "mean-value-ing" too

[vernal token]

Yeah, well they round to 17.4 maybe

These are just inaccurate measures anyways

[fathom swallow]

hellothere

[turbid ocean]

Yeah, it's probably just the average

[vernal token]

Thanks!

[turbid ocean]

I didn't help you though

We all just guessed

But I have no problem in saying no problem

[vernal token]

Are you still there?

[neat lintel]

Yeah, but I'm going in 2 minutes, low battery.

[vernal token]

Oh

[vernal token]

Ok really quick then lol

If we charge this capacitor

By turning on the switch

Then turn it off

Will anything happen?

Like protons moving off from the capacitor

[neat lintel]

Nothing will happen

The circuit is open

So current would not flow

[vernal token]

Can anything even go off from capacitors?

Like can it give off electrons

Or protons

[neat lintel]

If you connect that charged capacitor to another closed circuit, it will act as a cell

[vernal token]

In which direction will anything flow off from it?

From the plate that was charged originally by the current

Or from the other plate

[neat lintel]

Sent a photo in #chill

My battery is at 1% now, sorry to leave abruptly

[vernal token]

Np

Thanks

Afterwards, why does it flow off from the positive plate

And nto from the negative plate

Is there a reason?

@turbid ocean are you still here?

[turbid ocean]

Il be going on a metro and the network there will be crap

Also can't text while walking :(

[glass peak]

How do you guys like “reset” after a terrible exam? I really need to be studying for my next 2 coming up but even just thinking about maths is making me pretty miserable after how my exam went today, but I really need to do well in my exams after the weekend to make up for today

[loud snow]

Lies if youre in manhattan

[cyan goblet]

you're gonna do bad on plenty of exams in ur life, don't stress too much over one

seems like it matters a lot rn but it's insignificant in the long run

[glass peak]

I mean yeah kinda but I also need to average a 2:1 in all my honours classes to be allowed to do the masters course

And it’s just frustrating because I’m so shit at exams and every class at my uni bases their grades at least 80% on the exam. Like today, I opened the exam read through the problems and I felt really happy because I knew what to do for them all, but I fucked up basic algebra so badly that I didn’t even get to do half the stuff, like just to put into context how badly I did here, I got the eigenvectors of a diagonal matrix wrong.

It just pisses me off because I feel helpless, it’s not as though I’m not studying or anything, I understand the material, but it just feels like in every exam I get too stressed and I make so many dumb mistakes on stuff that I know and hemorrhage marks

Like every class I’ve taken at uni I’ve had at least an 80 average in my coursework (which for the UK is very good), I had a class last year where I had a 93 average or something, and I just made so many tiny mistakes in the exam that I only ended up with like a 73 after it all.

And I mean today I’ll be lucky if I even get a B in that class now, I just dont know what else I can reasonably do because it feels like I do this in the majority of my exams

Granted not to the extent I did today (I don’t think I’ll ever get over the eigenvectors thing) but still

[shadow flax]

You messed up the algebra so you spent a lot of time trying to fix it and not finish the exam?
People make mistakes even the professors too. You shouldn't really be concerned over the algebra errors.

Wrong ping lmao

Sorry whoever I pinged.

[sacred yarrow]

idk where to ask this but, isa year of practice enough for AMC qualification? I'm taking fairly high math courses but I want to get better at Olympiad math. would there be enough time to study for the next AMC to qualify for AIME?

[shadow flax]

I think you still get partial marks for setting up the problem even though you got the algebra wrong.

[cinder zephyr]

I'm about to have a terrible exam tomorrow 😭

Thankfully my last of the sem

As far as resetting idk what this says about me but usually the combination of "I fucked up" and "I have an exam coming up" is enough to get me to lock into studying

[neat lintel]

You fucked up the momemnt you entered formal education.

I forgot Math.

[slender glade]

since if you divide 1 by numbers closer and closer to zero, you get higher numbers, shouldnt anything divided by zero be infinite?

[neat lintel]

Can be formally proven why it "should not."

[arctic elbow]

Hey can somone help me with math pls

[glass peak]

Im guessing it’s your geometry one? I’ve also got geometry on Tuesday lol praying we both have luck with it

But yeah I focused so much on todays exam (and it did pay off I know the course inside out despite how my exam went) and I’ve hardly even started for geometry or my combinatorics and graph theory class so I’m in for a fun weekend

[cinder zephyr]

Manifolds ya

😭

I can't wait to be done

[glass peak]

Me either I’m so tired, so looking forward to finishing and relaxing for a while

All my friends from physics finished today and went out partying, I went straight back to the library

[rocky shuttle]

who needs parties when you have books

[glass peak]

I needed a beer after todays exam can’t lie

[sick kite]

you have friends that do physics? nowhere near snobbish enough

[glass peak]

It’s mathematical physics so it’s ok

[cinder zephyr]

Would kill for a brewski rn

after my exam friday I'm getting food with friends for dinner

will definitely get a beer or something

hey in 24 hours it'll all be over

that's my only happiness rn

[glass peak]

I hope it goes well, the post exams dinner with friends is always the best

[cinder zephyr]

can't wait to work on my projects over break

get my math blog started hopefully

[sick kite]

are you not planning to start a reading group?

[cinder zephyr]

was I?

[sick kite]

the rep theory thing

[cinder zephyr]

ehhhhhhhh

if someone wants to run one I'll join

I don't have the bandwidth to coordinate

[sick kite]

I see

[glass peak]

I’m hoping to take rep theory next year but it’s a semester 1 class with prereqs of group theory and comalg both of with run in semester 1 of the same year

Might ask about taking it along side and doing some extra reading over summer but it’s kinda stupid

[cinder zephyr]

the prof teaching graduate rep theory is quite quite awful

so I'm just self studying what I need for this reading / research-ish thing I'm doing next sem

[glass peak]

Tom Leinster runs rep theory at my uni so can’t say I’ll have the same issue

Obviously apart from the fact that it’s technically impossible for me to have the prereqs to even take it

That’s a slight issue

[sick kite]

another brit !!

[cinder zephyr]

genuinely the prof teaching rep theory next sem might be the worst prof in the department

I """took""" algebraic geometry under this guy

[glass peak]

(He did last time at least, it’s a topics course so the lecturer changes around a lot)

[cinder zephyr]

he taught AG assuming we already knew AG pretty much

he'd come in late, go way over (by like 15-20 minutes)

he'd have no idea what he was going to cover until class started

forget how to do proofs

and then say he'd finish the proof in a later class

and never finish

[glass peak]

Yeah that’s really really not good, did you at least manage to self study AG?

[cinder zephyr]

fuck no lmao

I'm retaking it in grad school

for sure

but at least I'll have taken commutative algebra so AG will be alot smoother

and I think I can argue getting out of intro algebra courses wherever I go to grad school

[glass peak]

I’m actually really looking forward to taking algebraic geometry next year, the 2 lecturers that run it are brilliant

And it’s algebra and geometry, so it has to be good

[glass peak]

Well… I’ll know the pain when I get there lol

[burnt ledge]

LOL

[cinder zephyr]

I've self studied some AG

from a different book that I've been meaning to look back at

Ideals, Varieties, and Algorithms

[glass peak]

I think thats one of the recommended books for my comalg course next year

[cinder zephyr]

It's a great text

[glass peak]

Is it good? I was considering getting it while the Springer sale is on

Well that answers that lol

[cinder zephyr]

Very very very good

[glass peak]

Yeah I’m sure that and Reid are the recommended books I’ll probably pick it up then, I read the intro and it seemed a little computational focused so I wasn’t sure

[cinder zephyr]

IVA is computational focused yea

So if that's not your thing then better texts exist I'm sure

But I'm a big fan of computation

[glass peak]

Yeah i was probably going to grab Reid because IVA seemed pretty computational but honestly if it’s on sale and it’s supposed to be good I’ll probably grab it, suppose it can’t hurt to see a computational perspective as well

[deep mango]

lmfao

well it does both!

but

no it doesnt actually do both, it converts geometric problems into algebraic problems and then algebraic problems into topological problems

[cinder zephyr]

If you like programming it can be fun to implement some stuff in Sage

[deep mango]

but whatever

[cinder zephyr]

SageMath my beloved

[glass peak]

I’ll let you know, my honours algebra class next semester makes us learn sage

I’ve not heard good things before now lol

[cinder zephyr]

Oh what

Sage is fine

It's Python so it's easy

It's not super fast but I doubt you'll be doing anything that required hours of computational time in that course

[glass peak]

Yeah I don’t think my friends said it was hard, I think they just found that section of the course to be very dull

[cinder zephyr]

Oh

Yea probably

Fun stuff will happen in IVA for example

I'm taking two math courses next sem which have decent computational aspects to it

Planning to implement stuff from class into Sage

[glass peak]

You seem like you’ve done your fair share of algebra, do you know anything of non commutative algebra? I’ve never really heard of it used for much but there’s a topics course on it that seems like it could be cool

The course description is vague even for a topics course so it’s hard to work out what it actually involves

[cinder zephyr]

I've seen it used in algebraic complexity theory

where you can "amplify" some lower bounds of the complexity of computing certain polynomials by looking at non-commutative polynomials

I can't explain it concisely lmfao

but trust me it's pretty stuff

[pale saddle]

BROOOOOO

[glass peak]

That seems like it could be cool, I really know nothing about algorithms and complexity and that whole area, the very small amount I actually know is from when my graph theory book spoke about PvsNp and NP complete algorithms and stuff when it spoke about the travelling salesman problem

It seems quite interesting though

To be honest I think I’m just going to end up doing the majority of the algebra courses offered at my uni

[cinder zephyr]

That's kind of what I've done

[cinder zephyr]

There's some cool algebraic connections

So the computational model are circuits

But now your gates are field multiplication or additional

Or scalar multiplication

Instead of and, or, not gates

And your inputs are elements of your field

And so your circuits instead of computing Boolean formulas

They compute polynomials in F[x1, ..., xn]

And so now you can look at a polynomial and ask "what's the smallest size circuit I need to compute that polynomial"

Where size is the number of gates

So like the determinant needs a polynomial size circuit (treat the inputs of a matrix as variables x11, x12, ..., xnn)

But if you remove the alternating (-1)^whatever sign from the definition of the determinant

You get a new polynomial, the permanent

And so while you can find a polynomial sized circuit to compute the determinant

It's conjectured you need an exponentially large circuit to compute the permanent

So there's this algebraic P vs NP

And there's supposedly some cool connections between this, algebraic geometry, and representation theory

[cinder zephyr]

This sort of stuff is where I've seen non-commutative rings get used

Yap fest over

[manic galleon]

Isn’t this just meta complexity?

@cinder zephyr

[cinder zephyr]

idk what meta complexity is

[manic galleon]

It also deals with circuit complexity

And the same problem that you defined

[cinder zephyr]

interesting

never heard the term before

[pearl moth]

it appears to be fairly obvcious, although i've never read the book so there are some unclear antecedent references that, if resolved, might offer more clarity than what can be divined frmo the text itself

i am also not trained in literary criticism, and so my analytic frame is more likely to focus on what can be concluded about the thoughts and intents of the speaker from the utterances stated. i also lack information about the relation between the speaker and the listener, or whether the speaker is a reliable testimoniant

[vapid ridge]

Yes you can have this in other bases

i might guess it actually happens for every base but i only just verofied it for base 16

111111111111111/F = 123456789ABCDF

Oh and i guess in base 4 as well, 111/3 = 13

and in base 5, 1111/4 = 124

and in base 6, 11111/5 = 1235

base 7 is pushing my powers of 7 knowledge and also mental maths capacity

but also in base 2, 1/1 = 1

and in base 3, 11/2 = 2

i sort of get the idea that metric spaces are involved

which i'm not scared of

but i rather hold off until i'm done with analysis and LA

@zealous garden

[open mauve]

i have gym and math

[little vine]

I have to drag myself to the gym

I hate exercise

I didn't used to be that way

[open mauve]

well if it's your first time it be pretty embarrasing

but you get used to it lol

my reps are even increasing

[little vine]

Cool

[limber thunder]

for me its not even the embarrasment I'm just lazy, unmotivated and get quickly bored from doing repetitive tasks

I'd love to do like, hiking or something more often

[spring falcon]

Where are you from btw

Yeah hiking is really cool

[open mauve]

just don't push too hard..

[open mauve]

[limber thunder]

yeah it's got great views and the farmside is so chill and quiet

Okay so the thing is that
I started a business early this year and am making thousands of $ rn from it but my parents want me to finish schooling and I know am kind of dumb in studies
So should I listen to my parents or should continue with my business @everyone

[ocean harbor]

you realize that the @everyone ping is off, why are you still trying to ping it?

also if you're already a business major then how come you dumb in studies? don't you need to finish high school or university first to become a business major or something like that?

I'm confused tbh but id say stay with your business

¯_(ツ)_/¯

[neat lintel]

guys my semester is over and i have a month before the next. what do

[visual breach]

Huh, what, FPGA with python?

Why do you guys need to make the world extra cursed

[pulsar pagoda]

http://www.pynq.io/

ask xilinx/amd

[visual breach]

Hmm actually jest aside, how is your opinion abt this?

[pulsar pagoda]

its trash

python is fine for RAD

and then u build the good stuff in something thats actually perfomant

like java/c# and if u care about perfomance cpp

python people are a cult most of the times

working on this has convinced me of it

[visual breach]

Based

[pulsar pagoda]

like

get ur product out in python quickly

get clients

make revenue

thats fine

but dont keep it in python

[visual breach]

I would like to restrict it only to prototyping stage, but opinions may differ there

[pulsar pagoda]

yeah I would agree for that take

[visual breach]

Once you get to production, you know

[pulsar pagoda]

its useful for rad on AI stuff

[visual breach]

It is somewhat hard to migrate

[pulsar pagoda]

but once u built ur product

[visual breach]

Yea, AI. Truee

[pulsar pagoda]

and that product is mature

move it to something good

like people need to understand python is a trash language

u use for getting shit done

[visual breach]

How does people end up with this kind of python cult

[pulsar pagoda]

but that shit is not good software by any means

[pulsar pagoda]

i blame guido

[visual breach]

Is he good at hype

[pulsar pagoda]

Guido is the benevolnet dictator of the python project

and creator of the language

but u know he could be an asshole like linus

but linux I can respect

because he actually has the technical background

[visual breach]

Yea

Oh wait

[pulsar pagoda]

and has debated academics like tanenbaum

and won

guido does not do that

So his position are on the side of convenience

[visual breach]

Yea I def get the random guy (not very proficient at programming) vibe

[pulsar pagoda]

which tbf are ok

[pulsar pagoda]

its not even proficient at programming thing

[visual breach]

Oh???

[pulsar pagoda]

its idc about hardware but I want to do hw stuff

[visual breach]

..is Guido himself like that

[pulsar pagoda]

No but he encourages

with the mantra of python

[visual breach]

Hmmmmm

[pulsar pagoda]

there should be one and only one way to solve a problem

[visual breach]

Ah that one

[pulsar pagoda]

if u want to abide by this u cant do hardware stuff

[visual breach]

Indeed.

[pulsar pagoda]

period

[visual breach]

I mean, Guido is not considering doing hardware himself, or is he

[pulsar pagoda]

no

but his language is pervasive enough it has come crawling to the embedded space

im looking at u micro python

and adafruit

[visual breach]

Yea I think the issue is on the userbase side then

[pulsar pagoda]

sec

[visual breach]

Yea this is beyond stupid, the very structure and design choices of python is nearly antithesis to embedded

[pulsar pagoda]

https://github.com/python/cpython/issues/66435

this could all be resumed to

python multi threading is slow even if ur doing multithreading and if u have to get down enough to care about this kind of cases dont use python

[visual breach]

asyncio has a guarantee that no other tasks run unless await is used. This creates an implicit "critical section" between any two await calls.

Wtf

[pulsar pagoda]

the joke here

[visual breach]

Well am I misunderstanding point of async here? This sounds horribly wrong

[pulsar pagoda]

is that people think python can scale

[pulsar pagoda]

ur not

their answer is

do manual thread management

[visual breach]

Oh god

[pulsar pagoda]

in a garbo language

[visual breach]

Huh

[pulsar pagoda]

like

thats literally what their saying

thats the consequence

if u have to await a critical section in a multithreaded program ur going to need to share state

[visual breach]

Maybe it's guido guy's overconfidence that is making people try

[pulsar pagoda]

mainly a lock

there was a major bug in pytorch like 1 year and a half ago

that was making it so AI convolutions leaked memory

but like bad

to the point u could not consistently measure resource utilization

problem was down to the cpython interpreter

[visual breach]

Seems like the bug I faced

[pulsar pagoda]

yeah

my friend placed a PR

got rejected

he ended up making a fork of python and fixing it

and using that

[visual breach]

I had some mysterious memory leak that somehow kills the program, IIRC was impossible to debug

[visual breach]

Oh.

[pulsar pagoda]

yeah

he doesnt fuck around

hes a cpp/c senior dev

[visual breach]

Now that pytorch is more of an interfacing layer to the underlying library, doesn't this mean.. python sucks so bad at performance that it literally causes problem with boundary usage?

[pulsar pagoda]

shhh

u dont want to talk about that

it will get its users mad

[visual breach]

?????

[pulsar pagoda]

basically software has a big part of it thats just build stuff that clients dont need

so that software companies can justify their exorbitant revenues

[visual breach]

Wait, was that real

I thought that was a rumor

[pulsar pagoda]

bro I worked for a company thats about to go bust

cause all the clients of that company were past startups from the founder

that just cared about getting user growth

getting their stock up

then selling

[visual breach]

Ouch

[pulsar pagoda]

I wont say names

but one of their clients closed down yesterday

and they removed most of the other clients they had from their website

[visual breach]

I heard of making a company and selling it, but did not know they also add in extras to products like that

[pulsar pagoda]

sometimes they add stuff to the main product

instead of making the baseline product better

making the baseline product better could be making it cheaper in the operations side

for example

thing is

if u have a software product and you need to optimize for perfomance, power consumption for example

u would need people with actual skills

[visual breach]

Indeed

[tame egret]

wake up chat

[jagged forge]

rapid development definitely requires skills, if you don’t want to be crushed by the weight of your codebase as it evolves

except you can go too far and spend too much time overarchitecting your code when you have $0 in revenue

but I object to the notion that software engineering not focused on performance optimization doesn’t take skill

[pulsar pagoda]

here

do u know why guido retired from dropbox?

[jagged forge]

idk anything about him

[pulsar pagoda]

basically dropbox switched from python to rust

[jagged forge]

oh

[pulsar pagoda]

once the porting was done

guido retired

[jagged forge]

that’s a wild switch if I ever heard one lol

[pulsar pagoda]

I mean they didnt kick him or anything

he left

[jagged forge]

though rust looks like python if you squint really hard

yeah i mean i guess he had nothing else to do

[pulsar pagoda]

except for being a cult leader

jk

jk

[jagged forge]

i bet shitty bloggers on medium are more responsible for that cult than guido

[pulsar pagoda]

yeah

I would agree with that

[visual breach]

Well I wonder how they come to love python

Maybe just because it is easy enough on the surface?

[pulsar pagoda]

i love how the porn link got insta deleted

[fervent flame]

i can tell ya that much

[inner orchid]

soooo help please fellas

also

how is a math minor

[dense belfry]

I believe!

That is enough

[last creek]

like math major but smaller

larger than math none

[inner orchid]

bruh

is it worth/fun

im a mech-e major

[last creek]

I did a stat major as a ChemE. Its main effect is that I now know way more statistics than a normal chemE. This is sometimes useful

fun you'll have to answer by yourself, but math is certainly useful/worthwhile for an engineer

[inner orchid]

what would a minor consist of usually?

ik i have to take calc 1 - differentials already but what else would i have to take

[last creek]

You would have to consult a specific program, as there's probably some variation. But you're probably get a chance to take more rigorous courses in real analysis, algebra, etc. that might be very useful if you go on to grad school (in engineering or otherwise)

In my case, I've found that I quickly found mathematical problems that were not easy to tackle with the math I covered in undergrad, and to understand the right way to tackle those problems, I needed a background in RA/LA and numerical analysis that I didn't have

[inner orchid]

yeah at the college im choosing to attend it just says 15 credits from any 300, 400, or 500 level course

[last creek]

Then you'll have a lot of freedom. Look at the courses and see if there's anything interesting/useful for what you want to do with your life

A minor is not a gigantic big deal, so the courses and what you'll learn is the important part

It might be useful if you're planning to work in a math intesive sector of mech-e, like CFD or FEA, etc.

do you all prefer your springer textbooks as paperbacks or hardcovers

[vivid halo]

as pdfs

[pliant moon]

Yes e-books/pdfs>>>>

[native badger]

Hardcover

[vale plover]

i agree

i have ranted about this a few times before

but why paperbacks over hardcovers? i guess paperbacks are lighter?

even if a hardcover is a glorified perfect bound paperback, there at least exists the possibility of opening it flat, at least in the middle pages, after breaking it in

springer hardcovers are cheaper than paperbacks in at least several cases

[limber shore]

Next year I’m going to be starting my undergrad, does anyone have any recommendations on what I should do when I enter to try to become competitive for graduate schools

[dense hornet]

So far, the only method I knew to be successful in a math class is to jump into the homework as soon as humanly possible so that you maximize the time you have to ask questions in office hours.

I also found that reading the textbook often helps since a good textbook might provide good examples

[fervent flame]

that doesnt answer their question to be competitive for grad school lol

[dense hornet]

I thought it might help to have a high GPA especially for accelerated masters programs
