How much would you guys agree that higher level springer books are too hard to understand via self-study, and/or could be replaced by an alternate source?

Books have their prerequisites, All Springer books that I've read so far is understandable for me.

and they shouldn't be replaced

Hello friends. I'm about to take Dif. Eq. this semester. I don't have Calc 3 yet so was wondering if I needed it before taking the Diff. Eq course?

Depends if your diff eq course talks about PDEs at all

#

If it does youll have a bit to learn

dusty river

Its a first course so I don't think it will

#

I'll be taking linear algebra and calc 3 as well so I hope any gaps will be filled as I go through them simultaneously

Usually the go to method would be to bring a pot of water to boiling

#

And dropping the eggs in for 6 minutes

#

Most of the identifiable math here is usually subconscious

verbal karma
#

Well, you do that in industrial settings where you need to design machine to actually cook food to specific conditions

#

But like, the argument on “average joe" is more or less too subjective. You can live a life only know arithmetic.

uneven tinsel
#

Okay I agree 100% to both of you

cinder zephyr
#

Basically when you send a message over the internet

#

It's just 0s and 1s, binary

#

Life happens, maybe there's some electrical interference, some of those bits get flipped

#

Now the message is wrong, very annoying

#

What happens is that we often append extra information to the message

#

That allow your computer to correct the errors after it receives the message

#

So that your communications and downloads and whatever don't constantly have a bunch of error messages in them, just the actual message

unborn ferry
#

But yes you are absolutely right

verbal karma
#

It is the bad part of math that you usually use it to make something and then done

#

Like, the cooking robot actually need to calculate those things when they are designing the system. But consumer can just press a button and let the magic happen

#

So, from the point of consumer, that is nothing math. It just a machine. But to make the arm moves or to think about withstanding material for the machine, that is just math upon math upon math.

unborn ferry
#

So to summarize from your standpoint is that for the consumer’s convenience, the thought of math using an automated machine to fulfill their task is usually ignored until the process to which how the machine does its designed purpose is seen from its own perspective, therefore taking in data and formulating decisions based off the data that is inputted?

verbal karma
#

Math in this process is like architect. You design it once and you are done

graceful flower
#

the machine realistically runs on thoughts and prayers of the engineers frfr

unborn ferry
#

The architect designs the design for mostly the intended purpose not entirety of how it works

#

That is the process it takes to design it

verbal karma
#

Yeah. Like in machine learning. You build a model and that is math heavy. But once you have that, you just serve that to customers. Like ChatGPT. You don't need to know math to use it. You technically don't need to know (advanced) math to build it. But you need math to design it or to make a blueprint so that you can code it.

#

At that phase, you push back and forth on design and testing. But once you have a product, you probably don't need that much of the complex math to use

#

That's why it is hard to put into a perspective when you want to use math in real life. You do use product of mathematics but not necessarily the math itself

#

Unless, of course, you are maker who makes those magic happen

what does even and odd mean here?

gusty socket
#

a q-handle is D^q x D^n-q with an attaching map out of S^q-1xD^n-q and even handle is even q and odd handle is odd q

#

and then a handlebody decomposition is going to be given by handle attachments to the boundary (but thicken the boundary so that it’s the right dimension)

#

if M is closed there is no boundary so any handle decomposition of M has to have at least one 0-handle

the harmonic number is asymptotically equal to log term + little gamma + O(1/x)

so when you take x-> inf

$\sum_{n \le x} \frac{1}{n} = \log x + \gamma + \frac{1}{2x} - \sum_{k=1}^{\infty}\frac{B_{2k}}{2k x^{2x}}$

what actually is GPA?

solid snow
#

grade point average

stuck token
#

cause I thought it was a high school thing specifically

solid snow
#

they assign points to a grade boundary and then average them out of all the classes you take

peak tide
#

universities have GPA too (in the US at least)

#

if it's too low they'll kick you out

# stuck token quantized marks?

your course marks get converted to a letter grade based on thresholds (A/B/C/D/F) and then for the gpa, some number is assigned, like A=4, B=3, etc

some schools have + and - versions of the letter grades, not all do

like A might be 4, A- is 3.7, B+ is 3.3, B is 3, whatever

they're changing one of the core maths modules for 2nd year here because "too many people are failing it and it's too difficult" but because of grade curving the average mark is like as high as it's ever been which is so funny

#

i think in the US (at least in math) grad schools know that there's a lot of variation in GPAs from one undergrad school to another, that's why things like letters of recommendation carry so much weight

# jagged forge yeah

I have a question. If you hear something pitchless like white noise, are you able to pick out individual notes?

#

Like can you suppress all other notes than, let’s say, A♭ and hear A♭ as the main note?

#

I can do that, but apparently it’s rare even with perfect pitch, so I was wondering if others could do it

#

I never thought much of it

north topaz

white noise just doesn't have any kind of pitch

#

it's like naming the pitch of someone slapping their hand on a table

fervent oyster
#

right

north topaz
#

but like even worse

#

cause there's no sound

fervent oyster
#

but the way I’ve learned about white noise is that it has all pitches

#

if that makes sense

north topaz
#

white noise produces the opposite amplitude of the surrouding noise

#

so that the resulting sound cancels out to zero

fervent oyster
#

i was told it was like hiw white light has all wavelengths of visible light

#

hiw-8

#

how**

#

like the kind of white noise people play from their phone

#

now Im curious about how we perceive that

#

like two frequencies with the same frequency (sounds wrong lol) but with opposite phases

fervent oyster
#

i wonder how that works

fervent oyster
north topaz
#

sound doesn't work like that

#

if you add together two different sounds it becomes louder

#

if you add many different colours, but using paint, you will get something very close to black

fervent oyster
#

oh

north topaz
#

it's only with light that adding many different colours gives white

fervent oyster

subtractive and additive color?

You have to get older to get better at math. You need to understand what 'math' is.

#

Being able to compute things fast in your brain is really a useless skill these days.

#

You need to understand the reasong and logic behind it.

#

I honestly believe a young person --- at least me when I was young (say, 17-18) has too many hormones flowing through him to be able to reason properly.

#

Plus, mathematics has dozens of subsets.

#

As someone who follows Hoare and Dijkistra's paradigm of 'structured programming', I have learned that it's all about 'domain anylasis', that is, reducing everything down to a 'domain'.

#

So for a high schooler or junior colleger: Reduce the problem to a domain.

#

And choose a subset you like

#

This is all respond to the 'how do I git gud at math' question someone just posted.

#

Not sure if it's a meme here. Apologies if it's a meme.

#

I'm personally learning how to prove my programs (both imperative and functional).

#

Also reading on metamathematics helps a lot.

uneven tinsel

worthy garden

Also I'm talking about Joe Q. Normal. There are of course exceptions to this rule that prove it. I knew this kid in high school who solved extremely hard problems.

#

Why. They all have a computer in their pockets don't they. Only a solar flare would stop it from working.

#

I'm personally trying to think in hexadecial and octal and do mind-computation in that base. I trreat my brain like a stack machine to learn it lol. But I still check vital stuff with Unix expr utility.

#

Thinking hexadecimal helps with OS development because you need to know a lot of buffer addreses.

#

But nobody trusts mind-computation with serious stuff. I am making a hobby OS that will only run on an emulator, and I still don't trust my mind.
Back when they made Boeing 747 they used slide-rules. Before that they used abaci.

#

Even buying a bag of Cheetoz (it's spelled with a z here), I would not trust mind-computation

teenage hormones affect your self control and decision making skills, but i've never heard anyone argue that it impacts your raw skills when it comes to something like math or programming

#

though i could buy that as you get older you get better at different types of reasoning

#

that said i do think saying teenagers can't do math because of hormones is wrong, or at least better explained by other factors

#

such as.... being more interested in other things

#

and of course there are many teenagers that can do math

worthy garden
#

Well I did understand basic continuous math like interation and differentation, and basic discrete math, and some linalg. Whatever they taught me at school I understood. I aced functions in 10th grade. In February of 2010 (11th grade) I was diagnosed with T1 diabetes and this mixed in with my bipolarity (I never cared what type I am because I don't tie my identity to the mental disease that I got, but if I am T1 I will be T1x2) really crashed my vitals, I had to sleep 16hours a day. I skipped 90% of 12th grade. Ended up staying a month in the mental hospital twice.
So maybe it was just my wexperience. lol.
