Has there ever been a bigger troll in the world of mathematics?
Let's Discuss.

i thought math used numbers?

bigger troll is not better troll

This is false, because a valid representation of n is infinity, which will make both sides infinity and thus equal to each other.
Hey /sci/. Math illiterate here. Gonna have to take Calculus next year after not doing any math for a little over a year. Highest math I took was Pre-Calc, but all I remember is basic stuff from Alg 1 and Geometry. How should I go about relearning everything? Khan Academy? Thanks.
>>7920417
I'm going to go out on a limb here and assume that you are not going for a math degree.
If that is the case then don't even bother. You will only need to understand calculus if you are asked to do proofs or some shit. Everything in calculus is given to you as a nice little formula and every calculus book is literally a bunch of formulas spaced out between long paragraphs of useless (for non mathematicians) bullshit to make you feel like you are learning but you know that for the test you are just going...

What if I'm studying in my spare time so I can really understand it and learn to model stuff with it? Spivak or Apostol?
I wanna into math maturity but it just seems impossible. Should I memorize something? Properties of numbers, sets?
>>7920850
Spivak? Topkek you're on your own with this level of ignorance
I hate it when engineering students refer to themselves as engineers...
Like you don't see med students calling themselves doctors or arts students calling themselves unemployed.
Or physics students calling themselves physicists, or math students mathematicians, or computer scientists calling themselves scientists.
Most math majors don't become mathematicians
Most physics majors don't become physicists
Most engineering major become engineers. Likely because it's such a straight forward career path.
>>7920401
I know this might be a completely foreign idea to math majors, being that it involves gainful employment and everything, but most engineering students take engineering internships while they're still in school! Wow! Would you imagine that?
Is there any reason why you can't hypothetically have a screen of hexagonal pixals, even for all intents and purposes they're inferior?
Like a metal window screen? Manufacturing costs.
For all internets and purposes I don't see why not.

What do I get if I make it passed level 9000?
Because I found an easy way to do it.
I'm at 'Just guess.' No idea what they want here... tried a ton of stuff already

How does a car antenna capture a radio signal when its properties are so different from the incoming signal? Consciousness come from itself we are just the antenna receiving the signal of life.
>>7919974
So, how is it possible that people with brain damage lose the ability to do shit, like recognising faces? If it was just an antenna you should only lose the ability to move your body, not the ability of thinking

>How does a car antenna capture a radio signal when its properties are so different from the incoming signal?
what the fuck are you on about? what do you mean they're different?
high people shouldn't be on this board.
sage.
>>7919980
If antenna is damaged it won't receive or process the signal properly. That's certain people with brain damage lose their motor skills but not their cognitive skills...vise versa.
Why care about anything in deep space? It's not going to affect us in any way and it's probably not even there anymore
>it's probably not even there anymore
explain
are aliens stealing our space?
>>7919844
since everything is moving and takes some millions of light years to get to us the object could be gone and it's light is just now reaching us
We're just curious, anon, that's all.
So /sci/ any good logic puzzles? hard ones please iv'e been getting into them but i just cant find any good ones on the internet.

That one usually sparks huge debate.But you are right
You're given the string of symbols ZE, from which you can apply the following transformation rules:
1) xE→xEU, meaning that if a string ends with E, you can add a U to the end of it.
2) Zx→Zxx, meaning that you can double the string that comes after Z.
3) xEEEy→xUy, meaning that if you have a row of 3 E's in your string, you can replace them with a U.
4) xUUy→xy, meaning that you can remove any row of 2 U's in your string.
For an example, you can do the following changes: ZE→ZEE (rule 2)→ZEEEE (rule 2 again)→ZUE (rule 3).

Is McKenna's stoned ape theory bullshit?
>>7919559
What would make you think this had any validity?
DUDE LSD LMAO
The stoned ape theory is stupid because it shows a fundamental misunderstanding of the evolutionary process. The theory is pretty much claiming that exposure to psychoactive substances caused physical changes which were then passed on to offspring, which is impossible. Enhanced vocal cords and communication centers in the brain helped create spoken language, not some shrooms

So I guess the gorilla meme actually settled with /sci/ ? Fucking kill me.

No.
Is psychology a science?
in school, the first year courses arent but the third and fourth year courses are. as well, you will do some data analysis.
they might not require proofs, nor will they require the calculation of the integral of the third cubic quartile gamma ray distributive property of illusive immersion to quantum lagrange, but they are pretty sciencey.
/sci/ judges psychology based on its first year courses and writes the entire degree off of them. based on first year classes, is it correct to say that compsci is just programming? no.
in the grand scheme of things, it...

Dumb gorillaposter
I see science as a sophisticated form of reverse engineering the universe and pretty much all we perceive, so yes,
But again, I am just a lurker, and not even /sci/ lurker.
I need ideas for a presentation for my 1st year uni math class.
I'm supposed to present a math problem using at least 1 definition, a theorem and a proof.
I asked /sci/ in the past and I know you guys got some great ideas.
>>7919334
Easy. Prove the limit of sinx/x as x approaches 0.
Definition: The definition of a limit
Theorem: Squeeze theorem
Proof: proof of sinx/x = 1 when x approaches 0
Simplest shit.
>>7919334
Present an isosceles triangle and the limit of times it can fractal into itself via ratio of 180*x! until the one of the factorings lines up over lapping eachother that create the degrees of the given factoring in both spaces of the obtuse angle that is left, when two of the degrees are switched ofc
or something like that, it's practicallity would be measuring certain spaces or phases for conductivity or purpose retrofitting
>muh programmable matter atoms stuff
>>7919351
Thanks, but we already covered that in calculus class. It should be something like perfect numbers or lucas numbers, some shit like that yo.
