Is a function [math] f [/math] uniformly continuous at any interval that is a single point? So if the interval is [1,1], would the function be uniformly continuous? Or would it actually depend on what the function is?

>>
>>8011817
what is your definition of uniformly continuous? if you're using the same one as wikipedia at least, then uniform continuity is a global condition and it doesn't even make sense to check it at a point.
>>
>>8011817
Are you high? Look at the definition again,look at your post,contemplate suicide,do it.

A point is an interval though

I've thought a lot about how to designed scripting and programming languages and I always run into the same problem: Control flow.

No matter how I look at it, in order to write programs, every programming language needs some way for the programmer to change the "shape" (execution path) of the algorithm. This is how the programmer imbues a program with logic to separate it from an empty state graph.

My problem is that I only know this intuitively; I have no idea how to prove it. If it's true I ought to be able to prove it, right? So how do I go about doing that? When I contemplate making a language without if/then/switch gateways am I basically asking how to do logic without logic?

That's the first time I've seen that image, and I actually laughed. Nice.

And yes, you do need conditionals. Without *some* way of the output depending on the input, your algorithm would produce the same result every time; even with slightly looser definitions, it wouldn't even be able to represent general functions (since no piecewise defined functions.)

To actually reach the full category of algorithms, you need both conditionals and some form of recursion/loops.
>>
>>8011857
So it's all by definition then? The logic of the algorithm is defined as the jumps?
>>
>>8011857

this.

if i remember correctly, look up "structured program theorem". you need some minimum of properties to be able to program.

as to prove this, ask some gauss here on board.

So if CS undergrads are pretty much code monkeys, what's graduate school like for CS? Like, what general areas does the research focus on and how rigorous is it? Are CS grad students actually innovative and talented?

I literally knew nothing about programming until a few weeks ago when I started taking this beginner course as an elective and it turns out I'm actually good at it and enjoy it greatly. I'm thinking aboit majoring in CS but I don't want to be a code monkey.

>I'm thinking aboit majoring in CS but I don't want to be a code monkey.

You literally cannot do anything else with a CS degree other than code.

Not even manage teams of programmers because the only degree that actually teaches this is software engineering. CS is literally codemonkey studies.

All CS are codemonkeys but not all codemonkeys are CS majors. This is a really sad truth of computer science, anyone else can get your job and will probably get paid more than you.

As a math major working as a software developer, I advice that you find something else that you like and study that, and then just learn programming on the side or take programming electives.

If you find that you are an empty shell of a human being and have no other talent or interest then go right ahead into CS.

>>8011711
Many CS advisers will tell you the major in something else in undergrad and then do CS in grad school.

Discrete Math
Data Structures
Algorithms

I would supplement those courses with Calculus I-III, Linear Algebra, Abstract Algebra, Analysis, Mathematical Logic (Advanced course)

Are the three "most important" CS courses you need to take. Ignoring OS, and other "applied" courses.

You can go into many different areas:

Artificial Intelligence; Computation and Language; Computational Complexity; Computational Engineering, Finance, and Science; Computational Geometry; Computer Science and Game Theory; Computer Vision and Pattern Recognition; Computers and Society; Cryptography and Security; Data Structures and Algorithms; Databases; Digital Libraries; Discrete Mathematics; Distributed, Parallel, and Cluster Computing; Emerging Technologies; Formal Languages and Automata Theory; General Literature; Graphics; Hardware Architecture; Human-Computer Interaction; Information Retrieval; Information Theory; Learning; Logic in Computer Science; Mathematical Software; Multiagent Systems; Multimedia; Networking and Internet Architecture; Neural and Evolutionary Computing; Numerical Analysis; Operating Systems; Other Computer Science; Performance; Programming Languages; Robotics; Social and Information Networks; Software Engineering; Sound; Symbolic Computation; Systems and Control

Guys. Make me a fucking curriculum.

By the end of the six years, I want to be able to go through this journey with the same knowledge as somebody who has a bachelors in mathematics, chemistry and physics.

If you could recommend some books on philosophy that'd be great too.

I've already done this on my own for two years while doing my chemical engineering degree and I'd say I'm reading master level books at the moment, but I'd like to get a stronger foundation.

Please don't recommend me the /sci/ dictionary since I've already read all of it. Please and thank you.

i think this is going to go sideways, but still. what's a good introductory macroeconomics textbook that isn't bloated? i'm used to reading math textbooks, so books like mankiw's that seem to drift from the core of the subject are annoying for me to read. i'm pretty sure the subject, at an introductory level, doesn't really takes 900 pages. i'm curious about how currency and trade work. also it'd be great if the author doesn't seem to be biased

Did we draw the short straw in the game of life?

Born good at music, art or sport:
>Wildly popular is school
>Can be in the big leagues from 17 onwards
>Not hard to get into so long as you have the talent
>Supportive environment where everyone is a winner so long as you try
>Girls are all over you
>Exciting social life
>Can do your own thing, no need to be in a company
>Can make a name for yourself

Be born good at science or maths:
>Usually bullied for it at school
>Girls mostly don't give a shit some even avoid you over it.
>Ultra competitive, all your ideas and work is constantly dismissed as babby tier until you have a PhD
>Virtually impossible to make a name for yourself
>Even more impossible to be an independent freelancer
>Career can't start until you're mid-20s and even then you're a junior underdog. if you get anywhere it is by the time you are mid-30s.
>Autistic arrogant strange peers

If I could I'd 100% trade being good at STEM for musical or sporting skill. Everyone I know who is good at these things is enjoying life much more than I am.

The truth is that, in reality, you're mediocre in math and science, and likely would be mediocre in sports if you were given an equivalent skill level; the other prevailing truth is that that mediocrity in either area will only get you moderately far in life - in fact, you'll probably go further with your comparatively low understanding of stem than you would with equivalent understanding in music.
>>
Why not both? I'm good at STEM and at sports as well as art. Get out level plen.

>Usually bullied for it at school
Nope, went to a boarding school where academia was everything. Try not being born a poorfag with parents who love you, idiot.
>Girls mostly don't give a shit some even avoid you over it.
The only type of girl who doesn't bore me to shit does.
>Ultra competitive, all your ideas and work is constantly dismissed as babby tier until you have a PhD
Not true, your work is baby tier because it's baby tier, nothing to do with your qualifications.
>Virtually impossible to make a name for yourself
See people like Kestler who earns over 200k for a single weekend's training session.
>Even more impossible to be an independent freelancer
See also literally any expert, firm or well known academic.
>Career can't start until you're mid-20s and even then you're a junior underdog. if you get anywhere it is by the time you are mid-30s.
And how the fuck does my internships from 18 not contribute to my career? Not only was I paid but the experience probably boosted my salary later, a career starts when you start building it, not when you start earning 6 figs.
>Autistic arrogant strange peers
Who I get along with better than normies.
