>fake proof in 1933
>another fake proof in 1942
>counterexample found in 1948

>Some days later I was with Artin in his office when Wang appeared. He said he had a counterexample to a lemma which had been used in the proof. An hour or two later, he produced a counterexample to the theorem itself... Of course he [Artin] was astonished, as were all of us students, that a famous theorem with two published proofs, one of which we had all heard in the seminar without our noticing anything, could be wrong. - John Tate

Euler's Sum of Primes conjecture was believed by a majority of mathematicians until a counterexample was found in the 1950's.

>>8788317
According to those who actually understand IUD, they believe it to be incorrect

Have a positive puzzle-solving attitude, try doing the problems on project Euler, it's quite fun to figure things out.

Read How to Think Like a Mathematician : Kevin Houston on Cambridge Academic Press (libgen.io is your friend).

stop seeing math as this archaic notation game perpetuated as something only very smart people are capable of.
dont look at the problems you see on /sci/ and on high university entrance exams and say "shit, im so dumb", and then hurt yourself emotionally

Dont think of math as a subject, that has only specific things to it. You're ruining the beauty.

Math is essentially anything that you can give structure and information to visually and logicallly.

Math is adventure into imagination and solving your own little arguments you've applied to things.
Let's try.

>Okay, so how long does it take to finish a tissue roll on a set volume, depending on the thickness of the tissue?
>Okay, we'll we know its a spiral, and it layers on each other.
>or fuck that, lets just appropriate to circles and test the relationship.

And just through fuckin about, I probably found and interesting relation or special cute equation involving sine functions and width of paper.

Maybe I can't even solve this problem, which means I have to look for more math tools, maybe calculus, or perhaps vector labelling will help me sort it out more.

You simply think of the most weird shit if you want to and if it interest you, and ONLY IF it interest you, play around with it.

It's literally having questions about real things, non existant things, heck maybe the size of pepe's lips compared to his face interest you.

It's just that we can use logic and thinking creatively to solve anything we want to and the challenge and retrieval of the answer, gives us the drive of fun and satisfies basic human curiosity.

You're not gonna get rich day trading

This guy is a PhD from Cambridge and wrote a 3 part series how to teach yourself math for doing Quant trading https://www.quantstart.com/articles/How-to-Learn-Advanced-Mathematics-Without-Heading-to-University-Part-1

Btw you never, ever want to waste money day trading or buying individual stocks. Imagine a hundred thousands machines all doing high-freq trading, TRADING ON UNKNOWN INFORMATION in terms of market release (because they're so fast), with the ability to react instantly to any situation because they're filled with machine learning AI algorithms designed by experienced quants and traders over decades.

All you can hope for is to put your money in a Vanguard index fund, but the bitcoin/cryptocurrency world is wide open to wallstreet type manipulation for low risk options

Consider the following OP

You are a 4chan autist who wants to learn to trade

80 of all volume of trading is done by large banks, hedge funds, and professional firms. When you buy a stock, you are doing so because it will go up. When you sell it, you are doing so because you believe it will go down. Somebody has to buy from you or sell that stock to you, therefore for every move you make, sombody is betting ON YOUR FAILURE.

We've established that 80% of market trading is professional. Therefore, 4/5 trades you make will be against somebody whose job it is to succeed on the stock market. Whose judgement do you trust more? Yours, or a giant institution with super computers at their disposal?

Its not a meme to say here the only winning move is not to play. Quite literally, the most mathematically logical move is not to trade, or at least to always trade the exact opposite of what you believe will happen.

What is his scientific background? That should answer your question.

>>8788019

He's an expert on thermodynamics.

He burned a church down and killed some guy.
Now he lives in the woods and makes tabletop rpgs

None of the predictions came true

Everyone realised it's just over-hyped politicised Jewery

People have more to worry about in their daily lives than keeping a harmless, invisible trace gas from increasing slightly in concentration

>>8787740
A bit of this, mix with the anti-scientific attitude being spread about. Then bake for about 10 years and you have your answer cake senpai

It became political.

Any amount of cigarettes daily is statistically significant enough to cause harm.

Any amount of cigarettes per week is also statistically significant enough to cause harm.


How much harm? that is relative, but unless it is a cigar once a year you're fucking your body over one puff at a time.

Think of your body like a self repairing machine that can only repair itself slower and slower. You can smoke a shit-ton when you are young, but when you get older you will be fucked.

I have seen so many old fucks in their 50's on oxygen, it's not worth it. After smoking for 15 years, I wanted to have children, and I couldn't dream of smoking around them. This was enough for me to quit.

You can only quit if you want to, and you can't just quit, you have to keep quitting until you only need one cig a day. If you are trying to stratagize about how many cigs you can get away with, you are still addicted.

The first week will be hell on earth. The second week you will get cravings, but as time goes on the cravings get less and less intense until you don't even care.

I still have dreams of smoking cigs, I don't think you can ever cure the addiction. It's there forever.

No dude... go to sleep.... just go back to sleep... I mean it literally, you must be stressed. Please just take a breather, and try your best tomorrow.

Test:
Is op fertile?:
IF YES: not simulation
IF NO: simulation

considering my monumentus strike of terrible luck i would venture life is not a simulation. unless.... my arch enemey of course could design a simulation in which i was totally fucking fucked

hope you enjoyed my drunk posting skills cause we have this thread on a literal FUCKING interval n i h8 u man

Elon Musk claims that we're almost certainly inside of a simulation.

stay mad

I really don't know /sci/ I want beer and pizza! Do science already!

>>8787148
That's how I feel deep down but I know it's hard for you guys, and you have a life outside of work. Something your teachers may not give a shit about.

looks like a system of equations to me, just put it in a matrix and solve it

It's great that all the hard math equations that had to be made for me to be alive, were all performed by someone else.

You can't teach genius, but if you spend enough time banging your head against a black board because you're too stubborn to give up, you'll probably be pretty good

Yeah it's called brainletism.

Nah seriously, it's called Dyscalculia

I don't know about you, but I exist to stay alive, but my opinion on the matter changes all the time

Starting with topology is odd.
You certainly _could_ if you were comfortable enough with abstract, proof-based mathematics but you probably aren't.

>>8786883
i should give myself more credit than i did. i am familiarish with very basic set theory proofs.

>>8786883
it's just i dont know analysis, but dont know if that is a pre-req for this book. i badly want to learn and want to know if it is feasible. believe ill start very soon and ask on here if i run into any questions after great effort.

They're putting chemicals in the water that turn the freaking frogs gay

It's a meme.

Are you using ZFC for these sets?

Suppose such a set A exists. Since A is a set, its complement C is a set. If C contains itself, then it can not be a set*, and then A is not a set, so C must be in A. Similarly, every set in C must be in A, but C is a complement of A, so C must be empty. Now A consists of all sets, and thus contains itself contradicting its own definition. Such a set, therefore, does not exist.

*follows from
>Foundation (Regularity): Each nonempty class is disjoint from one of its elements.
