/sci/ - Science & Math

>>7038827

I tried to a science degree at first. I was so terrible at lab stuff I switched to math.

>>7038850

Math fag.

The rest of the article is just as funny, definitely one of my favorite things The Onion has posted. http://www.theonion.com/articles/chickenshit-asteroid-veers-away-at-last-minute,2722/

I took a neuroendocrinology class thinking it wouldn't be too intense because it was crosslisted in the psych department. First day of class the professor told us we had a few weeks to learn the name and structure of every sex hormone (there are many more than just the couple people are familiar with), along with it's synthesis pathway from cortisol which meant the names and structures of every intermediate as well as each enzyme involved in the process. Our first few classes after that were basically that picture.

shouldn't that be continuous math?

Well, naw sheet nigga, how did we not think of that one before?

Posted it on /wsg/ since we don't have webms with sound yet.

1+2+3+4+5... = -1/12

PBF is quite good.

>>7042065
prove it

>>7042373
-12-24-36-...=1
Therefore
1+2+3+...=-1/12
Q.E.D.

>>7040945
Isn't 11.999..., 12?

>>7040438
kek
tempted to put this up on my cubicle wall

>>7040469
What about xkcd?

>>7040231
aha, this one was nice

>>7040469
SMBC is tired and just repeats the same jokes over and over again and Oglaf sucks dick, in every meaning of the phrase. PBF is the one true god of comics.

>>7043131
xkcd can be funny when it's not all "tfw no gf" or "LOOK AT ME I HAVE A GF"

Anyone who disagrees is probably just being a contrarian.

>>7043315
>>7043318
Damn, i laughed

>>7042633
It's a recurring joke on /sci/ that 0.999... doesn't equal 1.

>>7043551
Is it really?

>>7043557
its not, dont be stupid

[Almost] true story.

>>7040439

This picture sums up why modern people hate math. Seriously...Look at that picture. Some baby tier calculus scrawled out in a mess to look intimidating, when it's really the easiest thing since basic addition.

>>7043679
I don't think things like Wikipedia are helping either. As a learning tool for math it's atrocious, most of the articles read like they're written by someone with a BMath trying to show off how much they know.

>>7043333
XKCD is fucking terrible.

>>7043830
I don't think that's the issue with Wikipedia articles on math. The issue is that it's trying to be as complete as possible, without really ever explaining the basic ideas involved. Almost every introduction sounds like "[...] is a special case of [irrelevant and hardly useful generalisation] and is related to [List of things with increasing complexity]. It is named after [Some guy]". That just gives you no idea of what you are dealing with. It gives people not familiar with math the impression that they'll never understand it before they understand a million other things, one more complicated than the last.

>>7043845

Math pleb here and I completely relate to what you just said. I get more help from personal blogs than Wikipedia when it comes to understanding math concepts.

>>7043830
>>7043845
Could it be because... Wikipaedia is an encyclopaedia, the main purpose of which is to give the most in-depth and wide information possible, without bothering to aid people's understanding? The answer is in the name you fagets.

>>7043921
The Encyclopedia Britannica doesn't assume you understand everything in a given field before reading an article related to it.

Should a layperson need to know about epigenetics before being able to read the intro to the evolution article?

I seriously browse /sci/ because I believe it will make me smarter.

>>7044065
It may not make you smarter per se, but it would definitely stimulate your interest in science related stuff making you smarter indirectly.

>>7040262
Aw, I really like this one

>>7040940
I laughed more than I should have at "Michio Cuckold"

What? He's right. Real numbers aren't really used in discrete mathematics.

>>7044427
Underrated post specifically because I know a disgusting amount of people who confuse the two for one another.

>>7043551
>It's a recurring joke
>joke
It isn't a joke. People on /sci/ are smart enough to realise <span class="math">0.999...\neq 1[/spoiler]

>>7044402
I really like that one.

>>7044504
7/10
Not bad

>>7044444
Lol'd hard for science

>>7044504
1/3 = .333...
3/3 = .999... = 1

>>7044527
Clearly you don't even know how to write a proof.

If .9999... = 1, then:

1 - .9999... = 0.000...0001 = 1 - 1 = 0

Now, for any finite real number x, there exists a finite n such that x = n * 0.000...0001

BUT, if 0.000...0001 = 0, then x = n * 0, and thus all real numbers must equal zero! This is clearly absurd, and so I have shown that 0.999... cannot possibly be equal to 1.

QED

>>7044555
Oh shit, that one's legit. □

>>7044555
Do not let the trips deceive you, this is pure, unadulterated gibberish.

>>7044018
Wikipaedia doesn't do this either. As said above, it just goes deeper and deeper without bothering to aid understanding with some intuition-friendly pictures (unless the subject is elementary even to a seven year old - then they make sure you'll get the gist of it).

>>7044409
Very nice.

>>7044555
Flawed by saying first that a finite number equals zero in the second number

1-.999999....= 0

so it can't also be equal to .0000....000001. Nice try, but the more rigourous proof is done with geometric series and it is completely true that .999999.....=0

>>7044626
fuck, flawed in the second line

>>7044626
In a geometric series you start from n=0 so you can omit the (1/10) in the numerator.

>>7044555
>for any finite real number x, there exists a finite n such that x = n * 0.000...0001
This is an incorrect theorem.
You are basically saying "for any finite number x, there exists a finite n such that x=0n"

>>7044835
no it's correct
the flaw is in assuming 1-.99... = .00...01
this is only true if you assume .99... terminates, in which case .99... = .99...99 =\= 1

>>7045312
There's only one species of humans: homo sapiens
If you want to count all the homos, there's still only one living species.

>>7045313
False, there are three species:
White
Asian
Black
Jew

In order of importance

I assumed with this thing he chose axioms which allowed hyperreals to exist but permitted him to "solve" some other kind of problem.

>>7044479
You mean, the three.

>>7045313
Speaking of, is the designation "subspecies" used in a serious sense in taxonomy? Because why aren't different races (or whatever groups with genetic similarity) considered subspecies, or even domestic animal breeds? Are race, breed, and subspecies functionally synonyms?

>>7045571
because that would rustle some serious jimmies

RIP

>>7040942
I need posters of these

>>7045405
You are going against a lot of laughing that had been done.

>>7040222
But he's right, by the very moment a measurement could be carried out, the clone would already have been altered.
