Just how common is an asperger’s misdiagnosis?
I was diagnosed at 4 or 6 according to my parents. All I remember was being taken out of class and being given lots of tests. My mother then received a report from an evaluation team that stated I had Asperger’s and ADHD. I have a hard believing this diagnosis myself because I don’t feel like a sperg. I’m not really intelligent or anything like that. So how likely was it that the diagnosis was bullshit?

Considering that there is no medical/biological test for ADHD nor Autism, it's aggressively marketed pseudoscience repackaged as 'child care'. Autism/ADHD criteria are 'diagnosed' based on a list of behavioral 'symptoms' that defy or break social behavioral norms. They have no meaning beyond the question whether or not the child diagnosed with Autism/ADHD lacks self-care skills. I know from experience that autistic children, for example, are often deliberately not taught self-care skills because special schools/institutions have an interest in keeping them in as long as possible. Ask any ex-SpEd student. You literally have to go to court to get your child off the special needs register because the school doesn't want to lose federal money.

It's shameful because most of those institutions are just public schools with a spEd department. The teachers can barely deal with the students they get because they'll forever be stuck with the violent retards that end up taking balanced care away as an option, plus there's the risk of them hitting other kids there with zero repercussions.

What are the expression i can use in science to know the specific xyz vector position and xz yz xy angle of limbs in a multibody dynamics used in a nonlinear, dynamic, multiatittude locomotion cycle of a biped/quadruped system?

Basically poses generated from its motor pattern and its self-balancing symetry.

So ok here's an object i want to be able to simulate, for it to do something like this
https://youtu.be/J5bZr2yLt4g

basically have the limbs positions and orients accordingly to the motor pattern that guides it
obviously to start the locomotion follows wherever velocity vector goes
and then the inverse kinemacy then follows that vector somehow?? this is where im completely lost

please advice

You are utter trash. 9th thread on this board! If you can't figure it out by going to a prof or using a search engine you should do a different degree.

I did my biomed engineering degree without any help, while traveling 4-5 hours each day to that fucking institution, while doing 2 student jobs to finance my degree and my apartment I was living alone in giving me no social life or private time for years. Same time surrounded by people who considered me a lesser and gossiped saying I would flunk after the first few semesters, because they thought I was stupid. These same people didnt even care for my opinion in team projects and wouldnt have even helped me if I asked... and I still finished top of the class with top grades. Those retards were financed by their rich parents, needed study groups, lived 0.5 - 1 hour near the institution and still only came out mediocre.

tl;dr Being forced to do shit yourself makes you independent and learn better and an overall tougher person.
Seems only real hard niggers understand this. So stop acting like a queer!!

Well, in simple terms. If you say that a bag has no things inside, it makes no sense to say that the bag contains itself. It would mean you can find an empty bag inside the empty bag, but that's not true because we said the bag has no things inside, which includes itself being a thing even if it has nothing inside.

A set is basically a bag of elements, and is equal to another set if it has the same elements. "Set Theory" is developing this language about "elements" belonging to "sets", without getting those kinds of contradictions.

Gotcha. I think the problem of nothingness has a simple solution; nothing is the negation of thing, meaning nothing has no thingness, therefore it can't be said to be, since to be is to be a thing, but nothing is no thing, so it only exists insofar as it is a posited negation of thingness.

>nothing is the negation of thing
You're onto something. I think it would be more precise that we talk first about the existence of things. "Things can exist." Where? Let's say in particular where, like "X" for every time we say something exists.

Otherwise if we talk about existence of things in general. Then even if something doesn't exist in real life, since we're talking about the thing, then it exists in our minds. Even if it doesn't exist in anyone's mind, then it may exist in another realm that nobody has discussed or we're not aware of, like I'm not aware of the existence of many things in other countries.

It is problematic to negate the existence of something in every "X" because, we're talking about it, thus it exists in our minds and the supposition it didn't exist anywhere was false.

Nothing for me is short of, "In X you will not find anything that you can find in a Y not equal to X, regardless of which Y you talk of." And since I have defined nothing, it exists as what I said, a short for a bigger thought process. I do not think that talking about X and Y's is unnecessary because of what I said earlier, without those places of existence we're kind of talking nonsense.

I get what you're saying. I think it was Kant that really kickstarted analytic thought when he proposed that truly accurate language must be such that it posits (in a representative form) something existent that matches the conceptual qualities; if I have in my mind the concept Joe Biden, I posit something existent that matches the concept. In terms of "nothing", it can only be said to exist conceptually, but "nothing" lacks a referent, so it is basically a floating signifier.
