How do we effectively kill invasive species /sci/?

I know you're trolling on the /pol/ part, but invasive species are a threat to the global biodiversity. Science can learn a lot from nature, but at this rate there won't be any special or interesting species left in the future

I've read it across various boards, but never really got it. Why is compsci seen as a meme? The curriculum is definitely easier than say math or physics, but some claim that the whole discipline is a joke and stopped developing significantly since the '70-'80's or something. And they scoff whenever there is a mention of

>compsci

with their anime reaction gif.

Can some1 give a serious explanation of this meme?

Hey /sci/, I have a questions:

Is there more doors than people in the world?

>>7893872
Are we including car doors? If so, it's an unequivocal yes. If not, I still think there's more doors but I'm not as certain as if we're including car doors.
>>
maybe, maybe not

probably more humans actually
>>
Considering that in third world countries like china, india, africa, the middle east and also most of south america, people just do not have doors as they are safe without them. I'd say that there are more people than doors.

Linguistics is a science. It's not even a soft science; it's fucking science.
>>
>>7892988
I think linguistics is an extremely interesting and promising scientific endeavor, but it's unfortunate that there's so much disagreement among professional linguists. almost every subfield has a few divisions. in historical linguistics you have strict neogrammarians vs lexical-diffusion people. in morphology you have word-based vs morpheme-based approaches. in semantics it seems like nobody agrees on anything. in phonology you have mostly optimality theory people but there are definitely dissenters out there. then of course there's syntax, where there is substantial agreement among a plurality of linguists around minimalist/biolinguistic/chomskyan syntax, but there are a ton of (vehemently) non-mainstream proposals like the different kinds of categorial grammar, construction grammar, hpsg, lfg, gpsg, and other things.

Imagine a completely empty universe except for two hydrogen atoms. They are both separated by a googleplex lightyears, will they ever meet by gravitational attraction?

It depends on their relative velocity vectors. The possibilities are:

- collision: this is a singularity that requires perfect initial velocity including stationary relative to each other
- orbit: they go into orbit around each other
- hyperbolic/parabolic: they interact and go their separate ways.

Given their distance and mass it would be unlikely they ever meet.

Why hasn't he published any well-cited papers? Where's his alleged revolutionary theory in theoretical physics? Two papers (both co-authored) while a graduate student in physics is not what I would call "an IQ higher than Einstein".

He published what’s known as Barnett’s identity while working on his theory of quantum astronomy:
[eqn]\sum_{n \,=\, 0}^\infty n \,=\, \frac{{\rm e}^{\mathrm i \pi}}{11.999\dots}[/eqn]
He derived it by thrice iteration of integration operators and by evaluating non-trivial zeros of real valued second degree polynomials of a single variable. A very difficult work in topological probability theory.

Math noob/filhty autodictat here, would like an elementary doubt cleared please

Can I say that all real numbers that can be represented as the length of the one of the sides of a 2D object are not transcendental numbers?

Bonus points for examples?

All trascendental numbers have length and limit. The only thing you can't do is use transcendental numbers as results to fractions.

Sorry, sorry, forgot to add a condition.

The 2D object in question is an object that can be drawn with straight edge and compass in a finite number of steps.

I have a pure math degree. Decided to study mathematics that applies to CS. I don't give a shit about making video games, programming or any of the traditional CS shit.

The people I know think pure math and theoretical CS is useless and the only useful thing in CS is around making shit like web apps or programming. They think if you don't program then you aren't doing real CS. It pisses me off and I can't think of a good way to justify pure math or mathematics applied to CS. im really a mathematician pretending to be a computer scientist. What kind of arguments can I make to convince others theory is important?

Step 1) Stop being an insecure shit trying to convince an arbitrarily small number of people about your views (even if you're more intelligent than them)
Step 2) Thank me (your welcome)

I can't help but think that a need to prove the validity/applications of what you do to people who aren't from your field or understand your field (along with the field in which applications or validity is present), is just a bad, bad, life skill for any pure mathematician.

If you discover something solid, someone or the other is going to get it to use.

If you're just trying to make people appreciate what you know, it points to weak character.

Do you really desire for others to see what you see so badly? You spineless dependent slug?
>>
>>7891882
Thanks for the excellent reply. I mostly targeted it towards someone I know (close to me) that values programming knowledge over mathematically 'useless' knowledge (or useless in the sense it isn't meaningful unless applied).

You're completely right. This speaks more towards my own insecurity and need for validation and dependency. I don't need to justify studying to anyone. Plus, I don't really know if I should say I study "computer science". Most the programmers I know don't even know basic math & I don't program shit. Hank's for the reply anon. Saved it for future reading.
