How do astrophysicists actually know that once a cloud of gas becomes big enough, it collapses into a star? Such a process has never been observed. No one has replicated this in a lab at any scale.
>>16865958it just does chud
>>16865958>once a cloud of gas becomes big enough, it collapses into a star Inaccuracies in that statement aisde, we see nebulae at various stages in this process and can infer order on first principles.Massive objects attract other massive objects. As the mass increases, so does this attraction. Snowball effect ensues until attractive force is strong enough for fusion to occur.This is the most likely series of events based on what we see and what we know.

Are these real problems? Looks to me that is laziness and low iq problems.If parents disciplined their kids these 'neurodiverge people' would not exist.
2/10 trole, you're not getting a (You)
>>16865906I'm told if you beat these kids enough, they'll eventually act "normal". And if they don't, well, beat them some more. Apparently all of those conditions are fake. All it takes to get the kids to stop pretending to be anything other than normal is endless beatings.

>>16865906i guarantee they’re all more productive than you are christ cuck
>>16865906>Looks to me that is laziness and low iq problems.It is, to a significant degree, just that but you can't pathologize laziness because psychiatric formulation is meant to be morally "value-free". There's also good reason to omit any mention of resistance in order to promote the notion that people who don't give their best are medically ill and hence can be made to undergo treatment, even forcibly so.Low IQ has become a politically charged issue since the rapid and rabid promotion of the "equal race doctrine". It is omitted and ignored for primarily political reasons.

virtually every task I try to do take me 2x-3x longer than everyone else. I believe this is an ADHD thing. I am not talking about procrastination here I am talking about something else. time blindness or general distractibility or poor planning or something, I'm not sure.I just would like some scientifically supported solutions for this or at least some articles to read up on this phenomenon in order to try to work out my own fixes.I am already searching for readings on my own but I figure it wouldn't hurt to ask others for some extra help.INFO ABOUT ME:I already am medicated.I have recently started employing CBT strategies that do seem to help.I do not do any exercise but I plan on making cardio a mainstay in my routine (is this really as effective as I hear for ADHD?)My sleep schedule is non-existent but even when it is solid tasks take forever.I do not pay very close attention to my diet, I do not eat fast food or excessive amounts of sugar but that's it.if you have any advice I would appreciate it if it wasn't in the ballpark of>"put a loaded gun to your head and tell yourself that if you don't complete (X) task in (Y) minutes you'll fucking die."Thank you in advance. I appreciate it.
>>16864905Correlations are meaningless in determining cause in individual cases. If your ADHD cohort hypothetically consists of 3 % downies, trisomic defects will be found correlated with ADHD because Down's prevalence in normal populations is below 0.1 %, yet it tells you nothing about the other 97 % in the ADHD cohort.Psychologists should really get a grip on their logical fallacies because it shows we're dealing here with a pseudoscience.
>>16863692bad diet, parasites, and toxins cause adhd. its curable.
>>16863692I have ADHD, here's my experiences. Other than medication very few things seem to help. I've changed my life around, going from unhealthy and sedate to exercising every day and eating well. While I wholeheartedly recommend this for a slew of other benefits, I never found it impacted my ability to work at all which I guess is sorta disappointing. I'm still prone to variation in output, I think it has to do with allergies, but it's very diffuse and I've never been able to correlate it with pollen warnings etc. Hard to say if this has anything to do with ADHD or not.A few things I find to help concentrate is to offload my working memory. I do this by having lots of square paper and many monitors (my vocation is programming, I design circuits)>>16864548It's correct that ADHD isn't a disease in the same way tuberculosis, downs or parkinsons is, but it's still a useful label for us who suffer from the symptoms which fits the bill of having a deficiency of attention and hyperactivity compared to the baseline. Medication helps me do the things I love (which involve sitting in a chair designing complex components and coming up with testing strategies for these) so it's not just that I should be climbing in trees or whatever
>>16865894Then say you have moderate attention and hyperactivity issues. People engage in the same fallicious strategy of nominalism to justify the autism label, not realizing that a label that combines the quirky with the mentally retarded might be incoherent or useless. And anyway, labels like ADHD are suggestive in the sense of biasing people into thinking of attention issues as a singulary biological disease. It's basically a psychological trick used by pharmaceutical companies to promote drug treatment.
>>16865894And anyway, the posts here read like ChatGPT slop.>Medication helps me do the things I love It's not a medication, it's a drug. It adresses no actual medical need.>but it's still a useful label for us The binary dichotomy, them vs. us. promotes identitarian thinking. Because there's no ADHD, there cannot be an "ADHD group" or at least no such group that can move beyond a statutory exemplication of a set of all people having received a diagnosis X at some point.>so it's not just that I should be climbing in trees or whateverMany sociologists rightly consider the invention of ADHD to be the way an actually tightly controlled "free market" economy deals with kids who disengage from their work. It's not much different from the similarly problematic undercurrent in the way depression is defined that "being happy" is a moral or political imperative or the undercurrent seen in autism that developmental and mental health consists of approximating some statistical ideal as much as possible.In essence, once you see the ideological load in such diagnoses (and not just there), you see that the modern-day Western world isn't any more or less ideologically charged and hence divorced from reality than the Papal states or Hitler's Germany.
I see students running through the halls... pulling out hair... cramming... I don't wanna be like that. I want to leisurely browse my textbook in a relaxed pose. Occasionally I will stand up and stretch or take a sip from my water, milk, or tea. When I study with friends I want them to relax too. How can I make this happen? Has anyone ever tried studying while being totally tao te ching zen before? All the experiences I read about or see in media are bundles of nerves

Curry's paradox shows that mathematical logic is broken.
>>16864931>muh inductionanon, pls
>>16864931Logic is only used by the people making the logic so that they can feel smart when other people don't use their logic and they can say those people are wrong because they didn't use they logic they created to feel smart to begin with even though they don't even know anything because all they think about is logic instead of using their brain to think
>>16865054Induction: if you repeat something enough times and can no longer remember if you are on the current step, the next step, or the previous step, then you are done.

Why are "theorists" in physics useless pieces of shit? They are like completely happy with and proud of being spectators who smugly sit back and observe to give crappy unsolicited opinions. They don't just do that on everything, they also go and try to claim all the fame and credit for everything. These motherfuckers do nothing. If you aren't working with your hands, and instead you're clicking around on Mathematica with some illusions of grandeur, please kill yourself. Obviously you aren't even good enough at math to be better than the Mathematica developers. So just stop. Just quit. Go apply for your Goldman Sachs dream job and leave physics to people who can actually do things.
>>16865779Name two theoretical physicists since 1990 who have contributed anything of meaning.Expert mode: no phenomenologists allowed. Fun fact. Theorist became so detached from reality that the useful sector of them branched off and rebranded.
>>16865792>after 1990curious how you suddenly set time boundaries. I’m a HEP guy and you’re absolutely correct that that subfield has gone to shit. But stuff like plasma and solid state are well and alive. I just can’t tell you about the current state of these subfields because they’re outside my specialization.
>>16865890I have to set time boundaries because clearly theorists were significant in the '20s and '30s. There was also Feynman in the '60s, as well as developers of QCD such as Gell-Mann. Meanwhile, I'm sure you'll agree that after the '90s it's rather obvious HEP theory is shit. Something happened in the two decades of the gray area in the '70s and '80s. Which is precisely when people like Ed Witten showed up. The next question to ask is, of all the theoretical physicists that exist, how many of them are in HEP?
