I remember my physics teacher once saying that pretty much any physics problem can be modelled with a system of differential equations.
I'm a mathfag with absurdly little knowledge of physics. Does anyone here know how I can learn about this the best way? If anyone knew of a book dealing with this specifically, that would be awesome beyond belief.
Obviously I'll first need to understand a few physics laws, let's say that's a prerequisite and I'll have that covered once I get to the suggested sauces.

I never liked functional equation questions. It's possible I just never got gud at them, but the solution always seems to be "lol just plug in these random specific values and you win". There's no toolbox of stuff (that I can see, anyway) like there is for inequality questions or combinatorial questions or number theory questions or anything like that, it always just feels like it boils down to flinging shit at the wall and hoping you were clever or lucky.

>> No.11822028

It's honestly more accurate to say that the evolution of most systems can be modelled as a stochastic delay differential equation, and in the case of physics the terms "stochastic" and "delay" disappear.
Also, a lot of the optimization problems that show up in physics can be transformed into differential equations.

Because pretty much *any* continuous problem is a differential equation or boils down to one, okay, this might be a slight exaggeration but since even things like energy minimisation are ultimately PDEs it is unsurprising to find them in many places.

> If anyone knew of a book dealing with this specifically, that would be awesome beyond belief.

I mean in general. You have that the solution to something is a critical point of a Lagrangian functiomal(which means it's a local minima or maxima) and you pass to an Euler-Lagrange differential equation.

I can appreciate you trying to be reasonable in all this but as far as I'm concerned this is a trend I cannot tolerate.

This is the part that matters, not the identified and verified.
You're allowed to cite anything at all if you're just quoting it, or indicating it exists. Saying "anon proved" is not quoting, it's saying the contents of the post are correct. You can't claim something is true without appealing to a verification on Wikipedia. It's explicitly against Wikipedia policy to make any of your own judgements (not saying it always works like that at all, but in theory it should).

It's a stupid petty little tweak that was likely just motivated by not liking 4chan, but it's technically not wrong either.
It's also totally irrelevant since nothing was removed from the article. Trying "desperately" to stir up outrage over a shifted footnote reeks of "I'm 14 and I found /pol/ last month fuck the libs"

It is a well known fact that if over [math]\mathbb C[/math], [math]F(x,y,z)=ax^2+bxy+cy^2+dxy+exz+fz^2[/math] is a general conic, and [eqn]A=\begin{bmatrix}
a & b/2 & d/2 \\
b/2 & c & e/2 \\
d/2 & e/2 & f
\end{bmatrix}[/eqn]its associated matrix, then [math]F[/math] is irreducible if and only if [math]\det A\neq 0[/math].

However, I haven't seen, nor can I find a proof of this fact. I feel my attempt at it invokes too much machinery, and I'm looking to see if there's a simpler proof.

What I would do is - given that [math]A[/math] is symmetric, then it is diagonalizable. Changing to diagonal coordinates, then the conic can be written as [math]Ax^2+By^2+Cz^2[/math]. This is irreducible if and only if all three coefficients are non-zero, since we are in an algebraically closed field, and the latter is then equivalent to its matrix having determinant non-zero, proving the result.

It isn't torturing the grammar to say "gave a proof" rather than "proved", that's perfectly acceptable grammar and it's nonredundant because the two concepts are different. I think you're reaching by this point. If the general public does not draw a distinction between proof or correct proof, then they probably don't draw a distinction between proved and correctly proved in which case the original sentence would be perfectly fine.

that's not true, though

secondly, there are [math]\phi(n)[/math] generators, out of all the n residues

I explained why it's not allowed for this purpose two posts ago. And you (or the guy who responded) seemed to agree, since the response was to try and work around the issue by changing the sentence, which you'd only do if you accepted the reasoning in the first place.

Your explanation was that technically speaking it is not sufficient to say that something was proved on 4chan.

Yet you (?) pushed back even on this change. Why is it so important that the sentence MUST say "proved" instead of "gave a proof"?
>Since it was not published in a refereed place, the only evidence you have that the proof actually is correct is some secondary source that verifies it.
In this case the proof is 100% objectively correct, it has been verified already. What you are saying makes sense as a general principle, but one thing that I find about Wikipedia is their insistence on small stylistic requirements which always seem more invoked at some points of view than others.
Again, why is it so important that the sentence MUST say "proved" instead of "gave a proof"?

It's not. There's no particular reason it has to be phrased the way it is. You could rework it into many other forms that would be technically acceptable.
But there's no technical reason to do so, since the article is currently "stable", rule-wise. Nothing needs to be fixed, there's no content missing, and making those changes would add no substance to the page.
You don't give a shit about some little formatting tweak that moved a link two inches down, you just saw a screenshot that a feminist moved it and you see a chance to start some epic libtard drama.

Of course you're right that minor rules are irregularly enforced; I admitted as much in the first post I made. But that's not a reason to seethe when they do get enforced or act like they're somehow not real rules because some instances get missed.

This is not how Wikipedia works. If you don't like the way a sentence is worded you are completely within your rights to change the wording even if it's grammatically unnecessary. At least this should be the way it works. Unfortunately editorship is becoming more and more restricted and elitist as the years go on.

I wish that more textbooks would go through more examples instead of including a thousand exercises that I don't even know how to begin solving. I understand the point of having to do things myself, but if I'm just unable to do most exercises, then I learn fucking nothing. Call me a brainlet, but if the authors bothered to go through some of the exercises first then I'd have a much better time solving the rest of them myself and would learn a lot more from the book. It doesn't help that my lectures are fucking useless.

Reading a course in arithmetic by Serre is going to get you nowhere. For starters, you're extremely underprepared. The other guy is trolling you. Secondly, there's plenty of interesting stuff at the precalculus level. You should concentrate on dealing with the fundamentals first, even if it's boring. If you don't know precalculus well, there is very little you can do.

However, this doesn't mean you can't look into things that should still be at your level of understanding. I think one of the more interesting things you can look into is baby-tier analytical geometry. Stuff dealing with conics and low degree polynomials, or perhaps lines and circles stuff.
