How would one begin to study quantum mechanics?
Can I just pick up a textbook and start?
>>9129480
You learn the basics in any modern physics book. You should also know some vector calculus and linear algebra.
Griffiths qm is the defacto jumping point from there.
>>9129480
QM is a made up rule of the simulation. Like a casino where the payouts are random enough to convince the player that it's not rigged however rigged to the extent that it can be without making people feel like it is rigged.
That's basically the gist of it.

What's the best book on probability theory?
check out my blog. i have a bunch or probability theory resources and applications on there
>>9129429
already have. it's awesome. I was looking for something a little more formal though.

Can you direct me to your blog?
I tend to see you guys loving some autism, but I never hear all too much about ADHD.
The more I look into ADHD/autism, the more I see comorbid symptoms. Notably, both have emotional affect issues, both exhibit strange (usually ostracizing) social behaviors, both develop intensive focus on fairly select things and find themselves very uninterested in deviating, ect...
Moreover, both are seen as having major problems with executive functioning both of which seem to be related to dopamine dysfunction.
There's some interesting differences though. With ADHD, the individuals seem cognitively snared with respect to their ability to think analytically (likely as a product of a smaller prefrontal cortex than average). With autism, it seems that they're analytically capable at a much earlier age compared to average. It’s almost the inverse. Though ADHD is known to be heavily associated with developmental delays and they commonly end up being capable, albeit later than most.
Perhaps ADHD exists as a sort of lower magnitude form of autism or perhaps it’s some sort of off-shoot of the disorder.
Any thoughts? Why am I an idiot? Also try to consider the disorders in the context of children and adults.
>With ADHD, the individuals seem cognitively snared with respect to their ability to think analytically (likely as a product of a smaller prefrontal cortex than average).
So people with ADHD are unable to think analytically because they have small brains?
ADHD can be treated with medication like Ritalin. Those don't work on Autism; so biologically the two disorders are not the same.
A lot of very different medical conditions have overlapping symptoms. IMHO what you're doing is like thinking flues, colds, and allergies are the same thing because they all cause runny nose and soar throat;
Before you go spouting ideas maybe spend time with people diagnosed with autism or adhd. Maybe i can see what you mean with assburgers vs adhd, but even then its a stretch.
I was diagnosed with adhd 20 years ago, and spent time at a private school full of kids with learning disabilities, most especially autism and adhd. I didnt see what you see, the disorders appeared very different. Adhd is not comparable, even inverted, to autism.
IMO: When autism goes really well, its comparable to parts of impossibly serious ADHD, but when autism goes not so well, or worse, it is nowhere near comparable to adhd
Is time manmade? Is time itself nonexistent? Or has time existed for an infinite period beyond our comprehension before the Big Bang. Whatever it seems, I have come to a series of possible theories that may be beyond comprehension. The big bang theory, in itself is our theory of how the universe in general was created. It's the beginning of time for the creation of the universe and galaxies alike for the past ions. However, what if the big bang theory not only created the seemly endless universe, but also the creation of time, linear time. When the Milky way Galaxy was created, our planets where made from the reaction from the Big Bang theory. Earth, and other planets in our system revolved around the Sun, and that drove life for our planet, but it also drive us into creating time, which drove our evolution. (The suns up, gotta hunt, the suns down, I have to sleep). Think of the big bang for a moment as a rock being dropped into a pond with still water. When you drop the rock straight up, the rock smashes right down into the water. creating a huge "splash", and then ripples. Think of the big splash as the rxn from the Big Bang, and the ripples, which represents an ever expanding universe, which is never ending due to Newtons Law ( An object in motion, stays in motion). This ripple created unlimited reactions in the universe, creating stars, planets, and well you get it. The ripple effect in the pond is never ending when you look longer, it never rebounds unless it hits the bank. The ripple not only created the universe and galaxies, but is also drives time, and because it drives time, time is linear. Which is also why there is wormholes, they are like the ripples that rebound when they hit a boundary, or a the bank of the pond. What if time is continuous, due to the the infinite expansion?
Time and space are the same thing. Time is an effect of the movement of matter. As you go faster time slows down; at the speed of light there is no time.
Theoretically, if you go faster than light you go backwards in time.
>>9129385
This is completely incorrect pop-sci
Alright ya noobs, I'm settling this time travel hoax once and for all.
First and foremost: Time is an arbitrary notation created by man. If the whole concept were to die out, none of our (correct) maths would be any different. All you're giving meaning to is MOTION. Same with energy, there is no such thing, just different forms of motion. Kinetic energy is a pleonasm.
Now back to time. How the FUCK would you translate said arbitrary time notation to a machine somehow connected to space-"time"?
Pro tip: You can't.
>Time is not a physical "thing" in the universe.
Unless you manage to install a framework in the universe with a functional API it's not happening. Yes, mass and speed (same thing) slow down motion but that's it. You can slow down your RELATIVE MOTION as opposed to others but that's not time travel. There's no destination as defined by con-artists getting grant money for fake/stupid study and spend it on booze and cocaine (like my money).
Get over it. There's no such thing as fucking time travel. Niggers.
Also, time TRAVEL implies a destination. Beyond our high level, abstract communication method (which I'm not fond of either). Tell me, where exactly is next week? or last week? Break out the maths faggot, oh, you can't. Because even Einstein didn't predict destination-based time travel. And none of his maths allow for a stable "wormhole".
Checkmate muggles.
How do we know so much about atoms even though we can't see them?
Truth be told, a lot is actually not well understood about atoms. The present interpretation of it is by no means cold hard factual science - it's just the best we have.

what are you, fucking blind? how can you not see them?

Is there any truth to the notion that just maybe black people outwardly appear more threatening than whites people? Ignoring the connotations of the color black in general, are there other characteristics that make them seem less trustworthy and unapproachable? I ask this because if this is true, then this is obviously not racism as some leftists like to portray
>>9129305
>Is there any truth to the notion that just maybe black people outwardly appear more threatening than whites people?
If you have any sense of self preservation or, failing that, knowledge of crime statistics, then yes.
>>9129305
made me lol out loud
>>9129305
You chose the least threatening looking black guy for the picture kek
They usually dress themselves in a way that represents gang culture, and I not know about you, but gangs are pretty intimidating. Also their loud Ebonics sounds like apes that are group-fucking. I wouldn't wanna mess with a bunch of group-fucking apes....
How to make psychologist understand when I say that I can't think in language? I have to visualize the words I want to say, literally every single one of my thoughts is visual. No one else understands what I mean.
i bet his notes on you are awesome.
though at this point he probably just scribbles dollar signs instead of actually taking notes
What do you think of when you're thinking about a conversation you've had in the past?
That's interesting? Are you worse at communicating than most people?
> when the autism gets you a free bachelors degree of Biology, books, bus transportation, tutor, note taker, and (possibly) rent
You're in Scandinavia right? Autism bux only gives $700/month and food stamps in america.
>>9129268
I literally make about that much as a first year grad, so if he can get into a PhD program he's making twice as much as me.
However I would never want to be autistic for $700/month lmao

Someone explain in words cause i don't get it. Wtf is rational trigonometry and why is it different than regular trig?
>>9129183
It's defined so that it doesn't use real numbers. Because autism.
>>9129183
Something a crank on YouTube made up. Just ignore Wildbergerfags
"Regular" trigonometry is fundamentally premised upon a Judaic cosmology and axioms, you have to accept (((their))) conception of an infinite G-d to undertake it. Rational trigonometry on the other hand is purely Aryan and this worldly, it's a direct assault on Judaic presuppositions and that's why (((they))) refuse to teach it.
there's no giant diamonds in MY anus, /sci/... what about yours?
Uranus is terrifying. A huge, almost featureless sphere floating in the void.
>>9129110
>Uranus is terrifying.
indeed, so stop looking at my anus. there is nothing for you here. its a exit, so I'm glad its terrifying and featureless to you.
>>9129110
I agree with you.
But black holes are even more terrifying...
I'm sure the trolls will find a way to joke about this too.
Are there any scientific benefit of cardio versus lifting?
/fit/ is too autistic and low IQ to give a meaningful answer.
Cardio burns calories faster
I apologize that this isn't first post
>Cardio
Good for: heart, brainfog, depression/anxiety, neuroplasticity
>lifting
Good for: insurcurities and arms/legs
Bad for: heart
Cardio is for if you want to be thin and healthy. Weight lifting is if you want to be muscular and healthy. Both for otter mode. Neither for jabba-the-hutt mode

Why do 92% of our DNA is garbage?
>>9128831
>Article from 2014
Opinions are not that bombastic. Also there is a lot we do not yet know. Just because we do not fully understand our genome does not mean it is garbage.
>>9128831
>>9129941
Actually, a possible explination is that we have extra DNA, because our cells can't replicate the entire genome before splitting, this means we have extra DNA to compensate the tiny bit that doesn't get replicated.
These have a name Telomeres, however telomeres don't make up 92% of your DNA.
>>9128831
They are comments and documentation. If you remove them the ribosomes can't figure out how to put together the proteins anymore.
By "complex" I do not mean the hardest language to learn. I mean expressiveness of the language and the complexity of the grammar (for example I consider a language with singular,dual,plural more complex then one with just singular,plural)

Lol. Except programming languages or math. A language intended for communication (by humans).
>>9128862
>expressiveness
If by that you mean useless unneeded extra words for the sake of verboseness ... I'd say Spanish, maybe Itallian. Look a the word counts and book sizes of translated versions of the same story. Spanish translated books are sometimes twice the pages.
