I didn't finish highschool maths
I mean, start with the smaller fish; don’t try to eat the biggest fish, man.>>16895271Or just apply to a university and let the information flow into your mind if you're too lazy.Start with calculus:derivatives, integralsThen continue with optimization problems.Then move on to differential equations and how to solve them,Then go to Euler–Lagrange bruh, wtf.
>>16895269I want to learn from the ground up from the silicon germanium chips, not just a surface level understanding of software but of the hardware
>>16895264Sounds like you're running with a systems analysis brain. >>16895269>>16895272Are people that don't think like you and can't teach you these things. >Can someone tell me how to learn the maths concepts of these nibbas quickly and all the squiggly maths symbols their equations represent? I didn't finish highschool mathsNo, drill down. get another book. Look them up. It will benefit you profoundly more than it ever would the two quoted people because you need to learn it because you are able to hold it as a system in your head, as well as others and look at and compare them. They cannot, and can't even see how it would connect. Stop thinking you're stupid because you're uneducated, retard.
>>16895282why don't you start with subatomic particles? retard
>>16895264Learn what a semiconductor is, then see how its properties allow you to construct transistors to form logic gates.
But steel is heavier than feathers...This shit makes no sense.
Force of gravity: [math]F = G\dfrac{m M}{r^2}[/math]Force due to acceleration: [math]F = ma[/math]So: [math]ma = G\dfrac{m M}{r^2} \implies a = \dfrac{GM}{r^2}[/math]So the acceleration any object experiences doesn't depend on its mass or how "heavy" it is, only on the mass of the planet / moon / etc. For Earth this a = g.
>>16895778Good thing the moon isn't moving, the earth doesn't exist, nor the jun and nothing is moving and the densities are the same. Yes laymen's terms the hit the same time. The mass doesn't matter because of the inertia. Then you get to middle school.
>>16895772The objects themselves exert different gravitational pulls due to their mass, but these are entirely insignificant because the moon is so many orders of magnitude more massive. The moon's gravity is all that matters for the drop test.

How hard is the math GRE?And what are the best mathematical physics texts?pic unrel
>>16895268>>168952762x5=103x7=216x1=6These are all the center column and parallel, but the procession of the multiples that the other products are imparted from seem without excuse. I've been unable to rationalize the sequence of their allotment or partition.
>>16895286>How hard is the math GRE?Hard is relative. The math GRE exists to sort the top performers. It’s there to help admissions departments decide who goes to MIT or Princeton, and who’s relegated to the University of Michigan. If you’re applying to schools that don’t even require it, the math GRE is impossibly hard. If you’re in the thick of elite competition, it’s just another test to prepare for.
>>16895286The math GRE is a test-taker's test, in the sense that it's just as much if not more important to be fast as it is to know the material (which for the most part is relatively basic). Admissions programs are becoming increasingly aware of this too, which is why it's becoming increasingly (but not totally) irrelevant. Doing well is a minor boost to your application and not much more, it's definitely not "the difference between MIT and the University of Michigan" lmao. Doing unusually poorly might be a red flag, though. Just make sure you're practicing under timed conditions.t. got a perfect score
Scientifically speaking, is it possible for souls to exist?
>>16895733>I accept your concession.Yes, I concede that your mindless kneejerk reaction against some talking point you hallucinated is evidence of brain damage.
>>16895749>Abstractly, if two things share every property, they are actually the same thing described twice.You are confusing modelling with reality.If there are two indistinguishable people, doesn't matter how you can substitute things on paper, that's still two separate people in actual reality.
>>16895755>You are confusing modelling with reality.I'm not confusing anything with anything. You simply deny yourself any basis to assert there are two things.>If there are two indistinguishable people...You're not talking about people. You're talking about "souls", retard.
>>16895756If a hypothetical "god" copy&pasted the entire you right this moment, are there still just one thing, or are there now two, souls and all, despite the both of you been indistinguishable from each other in every way?This is such a simple concept any 6 year old child whose mind is not rotted by autism can understand.I don't see any point continuing this further as the debate is devolving into mindless insults. Austic midwits on /sci/ never fails to disappoint.
>>16895766See >>16895749>You've undermined the notion that you're really talking about two things, by first leaving the realm of physical concreteness...Since I'm 4 stdevs above you in IQ, I actually preempted the mistake you only now got to making. You have no idea what I'm getting at because your mental age is, indeed, 6. In any case, I'm bored with you.
What happened to whistling extra loud with your fingers?I have not met anybody under the age of 35 who can do it. It used to be that must adults were capable. What happened to human physiology in the past few decades?
>>16895643Unneeded skill, you probably can't cobble up your own shoes, burb on command or weave a shirt from linen that you harvested yourself all critical skills at one point or another.
I can do both with fingers and without. I can do it way louder with fingers but when you’re somewhere without a place to wash your hands it’s useless. I learned to do the fingerless whistle afterwards so I don’t put my dirty hands in my mouth.
>>16895717Ok unc
>>16895722Imagine that you lose your whistle and the search and rescue team can’t find you because you’re a pussy that can’t whistle.

The chud FEARS Professor Dave
>>16887338 (OP)Professor Dave joins Bill Nye the Science Guy claiming that there is a separate distinct axis referred to as gender and that your gender can be different from your sex. Richard Dawkins rejects this and he's far more qualified than Dave or Bill. I believe Dawkins is correct and the concept of gender is unscientific. Yes, a small population (0.1%?) has gender dysphoria, it seems to be neurological in nature. That doesn't mean you create a separate axis from sex to define this phenomenon. Dave using this paper as evidence:https://pmc.ncbi.nlm.nih.gov/articles/PMC6677266/I don't believe this paper backs up his argument. There's no such thing as gender, only sex, but there's a small population of people that neurologically reject the sex of their body. I believe this phenomenon is similar to how people with neurological issues might reject their own limbs and believe they are foreign objects/creatures attached to their own body.
>>16887338Never liked his instructional videos when I was a student because it seemed like his teaching style is oversimplified and catered more towards retard students. Now that he's doing more commentary sci-com videos, I just find him to be a cringe and morally preachy asshole. Reminds me of libtards and leftists who would scream at you for "being problematic" because you dare point out patterns and questioning mainstream thought because apparently it's a slippery slope to "right-wing rhetoric" (see his Sabine criticism video). Retards like this one always operate under their ideological worldview not so much based on objective facts.
>>16893713>>16887338Archetype of the circumcised mentality.
>>16894553>Retards like this one always operate under their ideological worldview not so much based on objective facts.Ironically, you're judging him based on a superficial comparison to "libtards" and his rhetoric instead of the facts that he presents, making you one of those "retards".
>>16895249I watched his full video and that's exactly what he does though. The entire premise of his video is that Sabine's criticism of academia fuels and leads to anti-science rhetoric, he doesn't even go over objective facts. You're just pulling a reverse-uno of "no u!" instead of actually pointing out the flaw in my argument, so who's the real retard here.
this shouldnt be allowed. such estrogen AIDSI fucking hate this guy, T. reddit incarnate. I hate nuclear, too. they are such faggots and he is an industry planttell me /sci/, what can I do to stop this? it shouldnt be allowedNileRed has inspired many YouTubers to do exactly this but the nuclear channel in particular is nothing but parasitic eating off of other peoples hard work and most of the time isnt even slightly related to nuclear - in other times he doesnt even have a clue about what is talked about in the video and is further from his expertise than nuclear to chemistry or math im not talking about disliking the videos so that I dont see see (not that it would work if big nuclear can pay YT to shove this onto my screen), I mean getting this shit taken down if he doesnt stop. this isnt about NileRed (I dont give a shit about him) but T.Fs practises which either should change or get him bannedalso, does this fucker even do any work? senior role nuclear power plant or something, its so obvious, also cringe, that he gets the role just to have 6 days of free time a week to do whatever, on a salary. the industry hiring safety sticklers and weewa safety bois that you wouldnt want to be around in real life, just to get him out of the building and make sure that if people see him, it is a bad thing. not to mention how he is a stickler for safety - which, nuclear - OBVIOUSLY the safest thing in the world, could do no wrong - wants to dickrideI dont want to simply report all of his videos because that will just lower MY weight on the actions that I might take against his channel in the future. I would rather plan it out and so I am looking for ideas or movement

if a naked singularity can actually exist irl, what would it look like?
>>16895684bot post
>>16895688singularities don't exist, they're mathematical expressions of some limit. singularities are just infinities that mean "wrong answer". are you really this stupid? did you even look up anything before posting? no of course not.
>>16894065It wouldn't look like anything. It would be too small to measure even.The reason things have a "look" when you look at them is because they reflect or emit light, which is not something a singularity can do. If you take away the event horizon and the black hole surrounding the singularity, then it would be completely invisible.

why do retards believe in this shit?
>>16894963Panspermia is unironically their best shot because life is completely alien to the material reductionist position. There could be a chemistry out there unlike anything that is known which makes life more likely. But it isn't merely panspermia. It is some alien race came from panspermia and with its knowledge created at least a second-order life which mimics their chemistry in the terms of the proteins in terrestrial life. You will have a hard time finding them admitting to this because it is bad optics.
Abiogenesis hints circumcision is an illusion.
>>16895190it's almost like circular reasoning is vacuous or something
>>16893567It's because they reject any sort of anthropic principle. There can be no explanation for them other than chance and blind force. Anything else is immediately rejected, as the whole scientific culture which grew them is steeped in a single idea - nature is ultimately meaningless.
What's this anon's >>16894180 deal? Is he some kind of local retard? Does he shit up every thread with his schizo babble
Anyone else think the "stay in school" genes actually have nothing to do with intelligence or IQ whatsoever? They keep being touted in genome wide association studies as proxies for intelligence, which I feel is horseshit. If anything most of these genes probably have something to do with emotional regulation or lower anxiety levels, where someone can stay inactive at a desk like an NPC and not be attacked with existential thoughts or feel like they need more physical activity. Basically the stay in school genes are actually NPC letzte mensch genes where you're less likely to feel anything. I personally ran my own autosomal file through the GWAS study Ed Dutton and Michael Woodly used to gauge the intelligence of ancient Romans and came "below average" in both polygenic intelligence and years of schooling even though I came 98th percentile on my country's version of the SATs, have a confirmed IQ of 140 on an in person test, got into an accelerated learning program through a standardised test and my dad is an ex Uni lecturer, so I frankly think the entire field is mostly statistical pseudoscience ATP
>>16895363why is AI posting here?
>>16895361>actually NPC letzte mensch genesThis is me. This is why I have so many fields of study under my belt, I (have) literally attend lectures while reading papers on entirely different fields, between gym sessions or video game matches or shitposts or writting papers in my head and psychically throwing them at the world. Im the "Last Ubermensch". Im not a playable character, as natural clones of everyone exist but not me specifically, as my clones are untermensch like everyone else.Its not entirely "Gene" related, the part that is isnt relevent to this or you in any way. You have a materialist mindset, a focus on chemical chains inside of you that determine who you are...its a sickness that festers itself into malaise. That mindset limits you and becomes a self fulfilling prophecy of learned (conditioned) helplessness.Stop being easy on yourself, externalizing resposibility IS the easy path...and one that will leave you empty and broken...and that is beneficial to idiotic Psychopaths who enjoy electrocuting peculiar little kids.Theyre still around and love positions of power like "reseach expert".
>>16895534>Theyre still around and love positions of power like "reseach expert".>>>/pol/526491557Imagine the power and exhilaration the Doctor felt, feeling they/them's anxiety and fear, pleads ignored, feigning comfort or sympathy, then soothing the traumatized victim...playing both sides as instigator and savior.[chef's kiss]Ive seen this myself, being I have years of experience across many medical fields of all kinds. The stories Ive heard first hand...
>>16895549>Ive seen this myselfMostly from nurses, as the doctors have a more rigorous labor to attend to, but not always. M.D. requires a certain level of Sociopathy that can be a kind of "dark attactor" energy source.The apathy to suffering was very apparent across the board though. Too many fakers not punished and now the genuine are ignored outright.Empathy to the disgenuine is a later crime against the innocent.

>>16893554you are confusing autism with intelligence.
