it's possible, but much harder. the younger you are the more fit your brain is for learning. when it gets older it starts focusing on retaining current knowledge rather than gain new knowledge

I just feel like I'm looking at it all with new eyes. My brain feels different and ready now. Is this normal?

How is salt good for you when it has chlorine in it? Does the benefit of the salt overpower the negatives of the chlorine?

>take home exam
Is this a joke?
I honestly cant believe that such a thing exists.

In all my classes homework is only needed to be accepted to take the exam and the note you get at the end is 100% a 1.5-2 hour exam. (occasionally they are oral exams)

You are basically gifted 50%-70% for free because only an idiot would not do the homework and getting 100% on the final is a given.

How can such a well known university have lower standards then my shitty local university?

>has never done an actual take home exam for a higher level mathematics course
dude stop, it's not linear algebra. some proofs are designed to take over the course of a day (if not longer) in the span of a group discourse and it's not the type of thing you'll just find on math stackexchange

The zeta function models everything, see e.g. https://en.wikipedia.org/wiki/Zeta_function_universality

mathematics is purity. its about what the world should be. a sphere is what we see when we look at a boulder or ball because we desire purity. the concept of smoothness, continuity, and diffusion all break down when we talk about reality because there is a discrete structure called atoms that make up our visible world. mathematics is archaic when encountering these models and is now self destructing due to the smoothness needed by relativity and the discreteness needed by quantum mechanics due to eigenvalues replacing degrees of freedom for elementary particles.

something newer will come that will treat mathematics like how mathematics treats philosophy; an idea that helps guide it but is too weak to bolster it against the relentless reality.

>>8905675
>what the fuck is mathematics?

Mathematics is logic of the highest level. It is when you turn off your human brain and wake up your inner eternal all powerful god and close your eyes to see a world much bigger than anything you will ever be, take some bits from it, and bring it to life.

Do you know what philosophers do? Well, imagine a philosopher but instead suppose he is actually intelligent. That is a mathematician.

>semantic architecture?
This is part of mathematics, though this is usually just contained in algebra.

>just raw instinct to quantify notions or ideas and give them structure so that they can be consistent?
In mathematics in general you cannot make things consistent because you are given consistent theories to begin with. But in meta-mathematics, where you look to create a theory in which mathematics can exist, the entire goal is to make it consistent so again, this is true about only a subfield of mathematics.

>where does consistency come from

Any mathematical logic book will define consistency. Consistency comes from that definition and that definition came from our desire to not have to worry too much because...

>why is it desired?
Because there is this thing called logical explosion that basically says that if you have an inconsistent theory, then everything is true and everything is false at the same time. Making any knowledge you extract from that theory literally meaningless. Therefore, only consistency can yield proper results.

>where does mathematics stop being consistent?
If you mean this literally then whenever we invent an inconsistent theory. If you mean this figuratively, when we poke at the outermost edge of mathematics, the fundamental axioms. Nobody really agrees on what the fundamental axioms should be, some mathematicians use some axioms, other mathematicians reject those same axioms. That's pretty inconsistent.

>>8905675
>is there a limiting case or boundary where we stop having stable models for things like finding solutions to differential equations?

Yeah, pretty trivial. As you know, there is no general formula to solve most differential equations. You can only reach general theorems when there is enough structure and with differential equations it is pretty easy to find something that has no structure at all and has to be tackled on its own.

>is it always connected to the fundamental axioms or can they be surgically removed to be with something more supporting to ideas that aren't reliant on completion, consistency, structure, or quantity?

Define completion.
And for the rest, yes it is.

>>8905605
Things become more difficult in that you need to actively "work" or "hold" more concepts in your head.

>maths
>hard to understand
Its only difficult if you arnt trying. Wikipedia and some other sites have literally all youd ever need to know to understand most of the shit.

The only actually difficult parts of math are the theoretical ground breaking parts describing things we dont even know exist. But thats all done by actual smart people. I.e. no one who would ever come to this board

When you burn wood, it vaporizes from the surface. The vaporized wood particles then react with oxygen, forming CO2 and steam. So it is gas.

Can a simulated atom break out of a computer?

Blow your brains out = Thinking outside the box

>>8904323

Once enough people know that the Universe is just a simulation, whoever is running the experiment will have to stop it because he won't be able to get any more useful information from it. So the only way is to convince a majority of intelligent beings in the Universe to accept the doctrine that the Universe is just a simulation.

[math]\int x^{-1}{\mathrm d}x = \log(x)[/math]

and for non-zero z

[math]\int x^{z-1}{\mathrm d}x=\dfrac{x^{z}}{z}[/math]

and so

[math]\lim_{z\to 0}\left(\int x^{-1}x^{z}{\mathrm d}x\right)[/math]

isn't the logarithm - it actually doesn't even exist.

But We have

[math]x^z = {\mathrm e}^{z\,\ln(x)} = 1 + z\,\ln(x) + {\mathcal O}(z^2)[/math]

which we can write as

[math]\dfrac{x^z - 1}{z} = \ln(x) + {\mathcal O}(z^2)[/math]

which we can write as

[math]\int x^{-1+z}{\mathrm d}x - \dfrac{1}{z} = \int x^{-1} {\mathrm d}x + {\mathcal O}(z^2)[/math]

or

[math]\lim_{z\to 0}\left(\int x^{-1}x^{z}{\mathrm d}x - \dfrac{1}{z}\right) = \int x^{-1}x^0 {\mathrm d}x = \ln(x)[/math]

I.e. the difference in switching limit exactly makes for a simple counterterm.

Similarly

[math]\lim_{z\to 0} \left( \sum_{n=1}^\infty n^1 (1+z)^n - (-1)^{1+1} \dfrac{1!}{\log(1+z)^{1+1}} \right) = -\dfrac{1}{1+1} \dfrac{1}{6}[/math]

[math]\lim_{z\to 0} \left( \sum_{n=1}^\infty n^3 (1+z)^n - (-1)^{3+1} \dfrac{m!}{\log(1+z)^{3+1}} \right) = -\dfrac{1}{3+1} \dfrac{1}{-30}[/math]

and so on...
