/sci/ - Science & Math

All of that,

>Analysis
>Algebra
>Geometry
>Logic
>Category theory

etc. is utterly useless.

I cannot get hired anywhere that requires skills. I have to work some min. wage job while I prepare for PhD studies then.

>Get a computer programming job

Yeah, a bootcamp grad is more employable than me. I don't know Node/React/Angular/CSS/HTML.

>Get a non-web dev job

Yeah, they assume you know what data structures are and quiz you on problems from a DS&A class

>Well study Data Structures

Yeah, that takes time and paying bills doesn't care if you """need time""" to study. Sure, it's trivial as a math major to study this, but it takes some reading to learn what linked list and so on are. They don't teach you anything practical in pure math.

WTF. I might as well got a degree in communications.

/sci/ prove you aren't a math brainlet besides your course grades and textbook problems

I'm trying to gain some intuition as to why countably infinite sets are defined as those which have some bijection mapping its elements with the natural numbers.

Is this considered some kind of "reduction"?

Maybe my question should be why the natural numbers are considered the basic countably infinite set. It may seem intuitive to you that N is countable, but that's not convincing.
