Isnt dark matter just normal mater on the other side of space-time?
As we all know, matter in space bends space down like a ball on a sheet, but what if you put some mass on the other side of the sheet? it would push up, yet be invisible from the top. It explains everything, why we cant see dark matter, yet we feel its gravity, why it pushes things away while normal gravity attracts. This begs the question however, how do we get to the other side? Are black holes just a puncture in the sheet and that's why they are black? (since we cant see the other side?)
Dark matter really doesn't have to exist.

I mean, that's up for debate of course. But, I really think dark matter and dark energy is just a big gaping hole in our understanding of the universe, rather than dark energy and dark matter actually existing.

Dark matter is not the same as dark energy.
The masses bending a sheet is an analogy, you cannot conclude anything from analogy.
The post is either bait or stupid.

dafuq are you talking about. i think you mean analytical philosophers, theyre more mathy than continental ones. plus, the continental philosophers don't like the maths because of its restraints and rigour.

Would failed literature writers solve a math problem? No.
Can someone of you recommend me some good books about computational linguistics? would be greatly appreciated

I just borrowed "Mathematical structures of language" by Harris. Can't attest to how good it is, I haven't got too far into it, and this isn't really my specialty (I have more background in math and logic). I just hope it's not too dated
>>8550452
I have a bunch of resources lying around somewhere. Will drop them after work.
90% of writings on the area are literally just counting ngrams and boring machine learning techniques 101, the part which crosses over with logic and grammar is more interesting.
Lmao you people saying you need math to understand science are so fucking stupid. I can visualize stuff happening like why the the light of the moon of jupiter takes longer to reach earth depending on where it is in the galaxy. And yeah, I can visualize time and space like a trampoline, you fucking retard. Where's your math now? Suck it.
>>8550221
your imagination is less precise than math, so basically your imagination is like a really shitty physicist
I suppose it's true you could visualize physical phenomena without math. But in many cases you'd need to understand the math to understand why those phenomena are the way they are.
Why merely visualize physical phenomenon when you could create computational physics simulations using the magic of mathematics? Food for thought.

>Is no one going to tell him that 70% of the class also got an A?
How does it feel knowing that your A just tells people that you were somewhat competent in the material you learned but not actually exceptional in any way?

He is one of the less retarded cranks out there in that as far as I can tell (I haven't watched everything he puts out) he does have actual math experience and nothing he says is really _wrong_ if you accept the premises he starts from
the problem is that his premises are retarded, for example he thinks that if representing your number as a big pile of 1s takes more 1s than the number of planck volumes in the observable universe, that means your number isn't a valid number

Pretty damn stressful desu. My SLs were geography, physics and french, while my HLs were math english and chemistry.
Math was god-tier. So much more rigorous than any of the math classes. Physics was ok. It's a little disappointing that IB designed the physics curriculum to accommodate math studies student. Chem was pretty good. All the other subjects were ok. English was my worst subject
>>8548462
Going to a top rated AP school in the US is a better option, had to do a bunch of idiotic bullshit for my ib program like ToK(theory of knowledge), CAS(creative,active, service), HL english &c.
>>8548462
The content is pretty good, could do without CAS, I just faked all my community service. ToK is babby's first philosophy class, but still I'd say it's a good thing that they include it for everyone.

I think you're looking fort more than just emotional warmth if you're craving warm and wet hugs.
Politics aside, is there ANY agreed upon science when it comes to transgender issues?

There exists a natural phenomenon called "genetics." The vast majority of humans are born with one of two sets of chromosomes: either XX or XY. If you have XX, you're a male. If you have XY, you're a female. If you have something else, you have a genetic disease.
This is science.
Are there any dangers to keeping your phone in your front pants pocket?
Ball cancer.

The hazards are different depending on whether you wear tight pants or pants meant for men.

There is no evidence this happens
What happens with hydrogen bonds when water dissolves salt?
I mean, are they still there, or they dissapear due to the attractions between sodium and chlorine ions and the water molecules?
Keep in mind the polarity of water requires that the sodium is bound to the oxygen atom and the chloride is bound to the hydrogen atoms. It will disrupt hydrogen bonding to some degree, but it won't eliminate it entirely unless you form a defined complex in which no hydrogen bonding is likely.
>>8552214
A high-schooler will tell you "nothing, they are still there", a chemist will tell "they assume a slightly different energy state/orbit", a physicist will tell you "we don't know" and a researcher computational quantum electron theory will simulate an approximation for you.
tl;dr: Your question is loaded and non-trivial.
Having an opinion about everything is a pretty stupid thing to do, especially because we often don't have the time or energy to think things through, yet we still frequently do it. I find myself accepting things outside my field I see posted here, but the problem is that most of people are doing the same. What are some popular beliefs about your field that are just plain wrong? What is something that I should know about your field that you would consider me well or decently informed? What about the opposite, which belief about your field reveals me to be a fucking idiot?

Neutrons "magically" have energy but not matter: Not.

Most people are severely ignorant: the ones who believe pasta grows on trees, people en mass overdosed on pot.

hey /sci/,
MLfag here. been thinking about different ways to make money off of Machine Learning (still in school, also pet projects are pretty fun).
Two that come to mind are predicting sports books/horse racing and online poker.
Anyone have experience with these kinds of things?
If i could get enough horse-data, random forests looked like a good option, since i dont think horses have long enough careers to make neural nets viable.
Poker seems like it would be saturated with people that got to it first.

There are already bots playing online, but I don't know how sophisticated they are, probably not very. They play winning though so that's one way to earn money. I know heads up limit holdem is a solved game, but state of the art bots can't beat top level holdem players heads up with deep stacks, see https://en.wikipedia.org/wiki/Claudico, so there's plenty of stuff to accomplish still.
Poker is not smart.
Your bot will basically just learn to play the odds of its hand, unless you do something really sophisticated.
A smart human player will be able to pick up on this after enough hands, and will bust your bot.
Sports is doable, but machine learning may be overkill. More traditional statistical methods would probably be more appropriate.
