I am helping a friend with a question for a comp science degree application.

The question states:
If SKU = 153 , SHIP = 156 , and STORE = 231. What is the value of UNICORN?

I've tried googling the solution, finding a pattern with the letters and numbers, different combinations for the three number sets for a UPC code or anything really but found nothing.

Currently the best answer I have is that unicorn is a term in the financial industry for a company valued at >$1b.

Another retarded solution I had was inserting the numbers given into the nine 0s in the >1b definition, resulting in $1,153,156,231.

Also this is from a university program sponsored by Shopify and they have an internal communication system called UNICORN but that still does not answer the question.

Any ideas?

Most set theory books have a very 'mathematical' approach to it that can make it hard to the non-experienced reader (basically because of their constant use of the 'mathematical proof').

But fuck it. If you already understand logic (if not read The Laws of Truth) and how axiomatic systems work (if not, try Metamathematics) I'd go for Enderton's and Jech's set theory books. Don't know much about category theory though.

Just out of curiosity, is that philosopher Alain Badiou?

And, what do you think were the influences for Schopenhauer's revolutionary thoughts? Orientals+Kant don't seem coherent to me

Self-studying basic geometry from Kobayashi&Nomizu. Apart from some mistakes and unconventional definitions (they define wedge product to be just the image of the alternation of tensor product, without the factor of (n+m)!/n!m!, which makes theorems have all these crazy factors), the book is actually pretty good.

Do you guys have any ideas what a differential geometry course would cover? Is it useful information? Is it applicable to computer science or computer vision? Here's the description:

"Possible topics are the basic ideas of topology, description of curves in space, definition and local study of smooth surfaces in Euclidean space (fundamental forms, geodesics, and curvature), global properties of surfaces, gauss-bonnet formula and applications."

I think the topic sounds interesting, but I have no idea what you actually learn. Is it just a combination of differential equations and calc 3 or am I thinking about it wrong?

Automata theory/regular languages.

Just took like at least two hours in a simple stupid fucking exercise, I feel way too dumb.

exercise asks for automaton which recognizes the language on alphabet { a, b } where symbols occur in odd numbers
build dumb automata that fail when strings are larger or when symbols are interleaved
get frustrated so I start procrastinating and writing/drawing nonsense
start getting suspicion that this may not be possible, argue to myself that it would require an infinitely growing number of states
remember even numbers example in textbook
it's literally the same automaton with just a different final state

I've obtained a series of textbooks for a distance learning course, intended to take someone of roughly my caliber, refresh their algebra, and teach them up to calculus. I'm trying to study it at roughly the same pace as I would need to if I were actually enrolled in the course.

Things are going okay so far. The series seems to be very well written in terms of difficulty curve/gently introducing concepts before building on them. It does assume that my algebraic fluency is somewhat better than it is (I can solve the problems but it takes me much longer than it should). I'm hoping I can fix that with lots of practice and the help of Wolfram's problem generator.

When I finish this I intend to do linear algebra, for 3D game dev. I tried doing that before, with my current knowledge, but found that although I could understand what a vector is and the concept of multiplying one by a matrix, I had no idea how to derive my own matrices or what it meant to have coordinates in one "space" and "project" them to another. Best to start over to ensure I understand what's going on.

You study properties of curves and surfaces. For curves, you learn about curvature, and torsion. Then you learn about surfaces. You can also study curves on surfaces. Properties of curves on surfaces include geodesics, which are paths that locally minimize distance between two points, and special types of curvature such as geodesic curvature. Then you study surfaces, such as fundamental forms, so you can compute notions of curvature of a surface. For example, there is mean curvature and Gaussian curvature. You link things together by the Gauss Bonnet theorem.

I don't know what you mean.

It's proof based?
Is Gödel's ontological proof math?

Definition 1: x is God-like if and only if x has as essential properties those and only those properties which are positive
Definition 2: A is an essence of x if and only if for every property B, x has B necessarily if and only if A entails B
Definition 3: x necessarily exists if and only if every essence of x is necessarily exemplified

Axiom 1: If a property is positive, then its negation is not positive
Axiom 2: Any property entailed by—i.e., strictly implied by—a positive property is positive
Axiom 3: The property of being God-like is positive
Axiom 4: If a property is positive, then it is necessarily positive
Axiom 5: Necessary existence is positive
Axiom 6: For any property P, if P is positive, then being necessarily P is positive

Theorem 1: If a property is positive, then it is consistent, i.e., possibly exemplified

Corollary 1: The property of being God-like is consistent

Theorem 2: If something is God-like, then the property of being God-like is an essence of that thing
Theorem 3: Necessarily, the property of being God-like is exemplified

Number theory.
Instead of the prime counting function, I'm looking at the function that counts numbers that aren't squares or cubes etc. It counts positive integers that are only first powers.

Everybody knows that positive integers can be written as a product of a multiset of primes.
n=(p_1)^(a_1) * (p_2)^(a_2) * ...

A similar result is that every positive integer can be written as a power tower using a sequence of first powers.
n=a^(b^(c^...

There is a way to write the zeta function additively instead of multiplicatively.
zeta(s)-1^-s = (2^-s)/(1-2^-s) + (3^-s)/(1-3^-s) + (5^-s)/(1-5^-s) + (6^-s)/(1-6^-s) + (7^-s)/(1-7^-s) + (10^-s)/(1-10^-s) + (11^-s)/(1-11^-s) + ...

It's a singularity in the metric. E.g. see
en.wikipedia.org/wiki/Schwarzschild_metric#The_Schwarzschild_metric
It's a sum over all trajectories weighted by the (exponential) of the action functional. Formally speaking you can think of the measure [math]\mathcal{D}\phi[/math] as [math]\bigotimes_{x \in M}d\phi(x)[/math]. For simple (non-gauge coupled) matter fields transforming under representations of a structure group [math]G[/math] (such as the spin group [math]\operatorname{Sp}(1,3)[/math]), the path integration corresponds to the fibre integration over the moduli space [math]\tilde{\Gamma}
= \{\psi \in \Gamma \mid \operatorname{Tr}(f_i(\psi)) = 0, 1\leq i \leq N\}[/math] of sections [math]\Gamma \equiv \Gamma(LM,V \times_G G) \subset LM[/math] (as a subspace of the loop space [math]LM[/math]) of the principal Hermitian [math]G[/math]-bundle [math]H \rightarrow M[/math] with some number [math]N[/math] of boundary conditions [math]\operatorname{Tr} \circ f_i[/math] imposed on [math]\partial M[/math] with [math]\operatorname{Tr}
: H^1(M) \rightarrow H^\frac{1}{2}(\partial M)[/math] the Sobolev trace map, while for gauge fields (such as in the case of Yang-Mills theory) the integration is over the moduli space [math]\tilde{\mathcal{A}} = \mathcal{A}/\sim[/math] of connections [math]\mathcal{A} = \{A \in \Omega^1(M)\otimes \operatorname{Lie}G\}[/math] on a principal gauge bundle [math]P \rightarrow M[/math] satsfying the self-dual condition [math]F = \ast F[/math], which amounts to [math]F^- = \frac{1}{2}(F - \ast F) = 0[/math] where [math]F = \nabla A \in \Omega^2(M)\otimes \operatorname{Lie}G[/math] is the curvature.
There seems to be some typos there. It should be [math]\sqrt{-\operatorname{det}(g)}[/math] in the action and there should not be a total minus sign.

you're not gonna get asked anything that requires too much of you - you will always have to exploit the symmetry. Usually that means parametrizing the surface of integration (eg: hyperboloid/paraboloid) or being able to choose a normal vector at each point in the surface (eg: a sphere or plane).

If it is not at all obvious that there is some symmetry, then it's going to be some application of Stoke's or Divergence theorem

Mathematicians use ZFC all the time
They don't, hence "irrelevant".

Constructivists are but one of the many schools of mathematics, but they are not the mayority in any sense or form.

An engineer would tell you
And how do you happen to know this? Do you often come in contact with them?
or some retarded shit
The shit you posted is no less retarded.

So what? Mathematicians use ZFC all the time so it's still true in there, even if you disagree with it philosophically.
Then you should have said something like:
every vector space has a basis if you assume the axiom of choice holds
or
yes if you use ZFC
but instead you came in telling us every vector space has a basis. Now you are retreating to your ZFC universe where you think you can be safe from my all-seeing gaze, but you have already humiliated yourself. Go to sleep and apologize to us when you have woken up.

There have been few times in my academic carreer that I had to specify I was using ZFC, because non autists usually assume it.

You might as well have wrote "every vector space has a basis if you assume every vector space has a basis".

Every vector space has a basis if you assume that every set has a choice function. It's also true that every set has a choice function if you assume that every vector space has a basis, but it's not trivial to show that.
Maybe not regular folk, but my peers are not faggots obssed with anime,.

Why the homophobia? How is homosexuality even related to this conversation? It seems like you are trying to make me look bad by giving me that stigma or alternatively trying to find intimacy online.

Why do we do anything we do? Why do you compulsively post anime in a math thread?

Actually it is trivial by definition, since the axiomatic system requires 0 work to go from an object to an isomorphic object within the category of axioms.

How do you know it's compulsive? You seem to be assuming quite a lot of extra, just like you assumed ZFC.

So using an anime pic in every reply you make in this general is not compulsive for you? I suppose you have a pretty specific definition of compulsive, just lile you cynically called me out for assuming "ZFC" even if it's the standard.

Why do you compulsively post anime in a math thread?
Why would someone not post anime on a website about sharing anime images? Why don't you post some anime as well?

It might be the standard in the "engineering community", but people here neither know nor care about that.

An action is compulsive when it is impossible to avoid it. I could easily post without pictures.
you cynically called me out for assuming "ZFC" even if it's the standard
How is something being a standard an argument that is supposed to make me believe in the existence of bases of all vector spaces?

That's when I have to become an adult and get a job or be unemployed, and neither of those will have any interesting math stuff in them.

Is there a job where algebraic topology is used other than data analysis? I don't know if I could do that as I have no programming experience at all.

Methshot

Yeah, it's called academia.
data analysis
I said "interesting math stuff". I doubt they use algebraic topology or sheaf theory in any non-trivial way.

Or just leave math behind. It was a phase, and phases pass. Mistakes like bad study choices were made, but that's life. Life sucks and then you die, I guess.

Low IQ, even lower ability to sustain stress. But it is true that I would fit even less in other places. I discussed that with my dad and he said he'll pay for my upkeep during my studies if I get a PhD because he's literally worried since I don't fit in.

I haven't watched anime for ages. I'd call it a waste of time, but here I am posting on Veeky Forums. It would look quite stupid to say that.

I should probably have done some programming courses, but it's too late now.
