I'm in a career in the private sector i'm very interested and enthusiastic about. I work with CS.However, i'd very much like to get into academia later in my life(when i'm 50, maybe). I don't mean to disrespect all of you folks who have dedicated their life to academic work. I'm sure it would be a long road in which i could take up to 10 years for it to be "succesful"(i wouldn't mind being very low in the ladder for the rest of my life really).I'm not sure if i'd stay in CS or maybe something else. I've even considered the humanities, to be honest.Academia fellows, have you met many people who took this path? If so, how do you view their situation and progression? Is there any form of "prejudice" towards older people?Thank you very much for your help

That late in age you will likely achieve nothing. Your best bet could be to adjunct or simply be an enthusiast and study in private. With a subject like mathematics the branch of computational study you can do that in private without a degree.
>>13770440>That late in age you will likely achieve nothing. What does this even mean? Publish a few papers and you just achieved something.
>>13770132If we get basic pay I think we will see a lot of gentleman scientists. I left the postdoc rat race because the pay was too low to handle my student loans.>>13770386Academia is brutal and it is getting worse. Scientific fraud is rampant. See /scg/ and the FAQ for details of the sorry state of academia.

Like for the people who jizz at calculing derivatives and integrals.What is so fun about it?I mean, I am not good drawing, but I do understand the fun with the pencil, making doodles of sexy anime girls and enjoying creating something (even if these drawings are shit and cringeworthy).But I don't see the enjoyment in doing numbers, like, you must be mentally impaired to find numbers arousing.Like who in his sanity cooms to numbers?What's the enjoyment in that?I can picture someone with certainty, to draw for hours, but I can't picture anyone in his sanity to spend his day solving calculus in his room while he could be better off playing vidya.Can someone explain this to me?It's a legit question.

>one simple equation creates infinite complexitySeems kinda sus. How does science explain this?
>>13770139You can be confused by something without understanding what it is.
>>13769247learn english shit skin.
>>13770350You just substituted "equation" to "base" and "[result]" to "construction".
>>13769208>Why not say how this is in your mind and it's what happens when you do/write out the calculation and then look at it?Its not what is in mind - its in the structures themselves, my mind cannot comprehend them, it can only ways around them and use tools of modern mathematics to access those things. If you tell that pi_15(S^8)=Z_84x(Z_2)^5 is something not totally incomprehensibly complex >Saying "equation that creates infinite complexity" is kind of meaningless and abstract isn't it?The example of homotopy groups of spheres proves you wrong. No human has put in homotopy groups of spheres or semisimple lie algebras or representations of spin groups or L functions into mathematics, The aforementioned pi_15(S^8)=Z_84x(Z_2)^5 is an absurd statement, the only ways to come up with that are to randomly generate abelian groups and talk shit or be God, because nobody in the universe expected that from just the definition of a homotopy between two maps these kinds of absurd structures would emerge.
>>13771282>its in the structures themselves,Truth is subjective.
How could we leverage the temperature gradient from Earth's surface to not-the-surface to do work and generate electricity? I am imagining very tall metal poles with some sort of passive heat engine implementation.
>>13770526>I am imagining very tall metal poles with some sort of passive heat engine implementation.I've seen something similar proposed before, it's technically possible but not feasible.
>>13770589Of course it should be a steam+turbine setup. His question basically boils down to "how do we evaporate water at sea level while supplying less energy than we're getting out at the top".

Bros how do I pull a 95 or something on an exam in 3 weeks for a subject I'm averaging 60 on in highschool. The subject is specialist maths and my teacher said he believes in me and thinks I'll do great in the exam and I don't want to disappoint him how should I study to maximise my score I think I will be able to understand every concept if I study well but I'm not great at test taking so I need advice on preparing to maximise marks.Current plan is to do like 20 practice exams.
>>13771174Do the exams with a timer
do the practice exams, first couple without timer and just try do it as best as u canthen revise the stuff u lost marks on. do practice problems in that topic or read up on itwhen u feel more confident do the same thing just with timerbtw y are u doing bad? like other than understanding of concepts are u spending too much time on difficult questions, managing time inefficiently, etc
>>13771821I'm doing bad because I've failed to apply myself but I like the teacher and I really don't want to dissapoint him and I want to get my mark a lot higher. I'm doing pretty okay for the effort I put in but I'm still unhappy and think 90 something on the exam is feesible
>specialist math>highschoolThat's more like entry-level math.Do some exercises, some timed practice tests and you'll be fine.
>>13772079The course is called specialist maths. It's in Australia it's just like 3d vectors integration with trigonometric identities complex number locuses and like 30 other things like that.I really hope the practice exams will be enough but yeah I'm still nervous
Is gender dysphoria (Trans genderism) something that can be cured with dedication and therapy?If so why isn’t it being used or researched?
>>13770747Second time's the charm, bro. Godspeed.
If drug companies wanted to make money off of a group the first group they would target would be menopausal women not gender dysphoric malesIf they really wanted to profit then they should try to pay for a lot of studies to be done on the health effects of transdermal estradiol and bioidentical progesterone and show that it's safe and effective, this would undo a lot of fear women have around HRT due to the WHI study which was terribly done and made a significant % of women stop taking their HRT and a lot of doctors unwilling to prescribe itIt's interesting to see what the consequence of this shift has been, no longer are women comfortable getting pills to treat their condition (i.e very low estradiol and progesterone) but now they're encouraged to 'accept it' as a natural state of ageing and they do that with constant therapy, anti depressants, bizarre treatments like lasering women's vagina's to treat the symptoms of low estradiol, etc all of which are very expensive and profitable compared to HRTIt's funny that people act as if pimozide would somehow be better when companies profit from it far more than they do with HRT
There's a difference between transgenderism and gender dysphoriaIf a trans person can function normally in society with no episodes of suicidality or other damaging symptoms, then who fucking caresBut if they're actively in a state of serious self-harm, then that's when therapy and support usually comes into play
>>13770784Oh that said, the entire apparatus that governments have built up around trans healthcare is certainly a way to profit from trans peopleForcing adults into years of therapy in order to prove that they're valid enough to be prescribed HRT is probably making them a lot of money, especially when you add in mandatory endocrinologists, for kids it's more complicated admittedlyThe better way is to have informed consent and a GP who can check your blood work out themselves

All I want in life I to have a secret underground genetic engineering research facility. How can we make this a reality?
>>13771847You don't need it to be secret and it doesn't need to be underground.Labs are cheap and in the USA, we have free reign to do whatever we want, even modify a germline, we just aren't allowed to receive public funding for such research.
Have you ever considered going to uni?
>>13771847I have a selective breeding research facility, its above ground. In its decades of history genetic engineering genetic engineering has so far produced "roundup ready" plants and nothing else of any use. selective breeding on the other hand has produced thousands of useful new hybrids in every category of life and its done so in only a few centuries. selective breeding has a much, much better track record of effectiveness and usefulness on per year basis, even over the past few decades since genetics have been around to compete, selective breeders have still outproduced geneticists in every category by an outrageous percentage and all that regardless the tremendous advantage genetics has in public research funding. genetic engineering is pretty much a failure, people get their notion that it a potent field of investigation mostly from soience fiction fantasies like comic books, movies and tv shows, but the media propaganda is sadly misleading, geneticists don't have the comic book press button black boxes to make new forms of life, they don't have anything like that, they don't have any valuable or worthwhile capabilities at all, virtually all of the useful new forms of life are created the same way they were millennia ago, through selective breeding.
>>13772033Stealing gear from university labs is good way to gather inventory for a home lab. The people at the universities never take care of their expensive science gear, they treat it like public property, so its easily liberated by anyone who wants to put it to better use.

I like to watch most animals suffering emotional abuse and I enjoy seeing >some< types of animals suffering physical abuse, but I could never bring myself to harm an animal in either of these ways. I firmly believe animal abusers should receive mandatory prison time and execution for chronic offenders.Is this a quirk of evolution? My upbringing? Why am I like this? How can what I feel be in such opposition to what I think and know is right? I grew up on a farm so I shoot pest animals and although I'm used to it I still get annoyed at myself when I do not get a clean, instant kill, but then I can watch animals being abused and I get some kind of new emotional rush, a positive emotional feeling from it that I haven't experienced before. Is this common?
>>13770956I like rekt threads because they are a tether to reality -- I like to see something realsuch threads were hard to find before the internet -- so I appreciate them doubly for this reasonI don't know if you feel the same way. Personally I get zero sadistic enjoyment out of watching an animal get tortured, but I watch it anyway -- if you do get sadistic enjoyment I'd say there's something wrong with you. Don't sit in a halfway house you little fag.
>>13770956You are a sociopath. Seek help immediately.
>>13771103>>13771115How can I be a sociopath or a sadist when I can't even hurt a person without feeling regret? There have have times in my life where a friend has been assaulted and I have then assaulted the perpetrator and I STILL feel bad, even when I'm in the right.I don't believe this is as black and white as 'that means ur a sociopath/sadist' this is a very complicated issue. I can't even verbally hurt a person without feeling regret and yet I can watch it and feel good.

Can anyone describe what happens to planets during a supernova? Maybe use our solar system as an example of arbitrary distances and planet types. Couple of thing I don’t get:>do planets close to the star get literally destroyed?>outside of a resulting black hole, do further planets escape orbit as mass is ejected out of the center of the system?>can stellar material get caught by large planets, and what would that look like?
>>13771822it would be very painful
>>13771822Im not a space doctor but i would expect the whole system would be completely destroyed given a single super nova event emits thousands of times the mass of the suns energy in an instant, ejecting star sized chunks of matter omni directionaly, probably would perturb nearby systems also. Have you read anything that makes you believe this wouldnt be the case?
>>13771822>what happenseven neutrinos become lethalhttps://what-if.xkcd.com/73/
>>13771921No idea, but conceptually it’s hard for me to understand. I imagine the mass of the star expanding outwards in a violent explosion omnidirectionally. But by the time that expanding sphere gets to like Jupiter out there I have a hard time imagining how much mass would actually be impacting the planet at that point.
Medical student here.You are all pretty stupid to think that there will be long term side effects of COVID. The vaccine was not rushed out, because the reason why it came out so fast is BECAUSE they were studied on previously. The mRNA vaccine has less side effects than a regular vaccines. Regular vaccines are heat sterilized or otherwise parts of ACTUAL bacteria/viruses. And you need an adjuvant (chemical or substance) to trigger immune response. mRNA vaccine is a strand of mRNA, mRNA is legit something you produce all the time for protein synthesis and gets degraded immediately.It has no impact on your genome DNA gets transcribed into mRNA, the mRNA then leaves the nucleus in regular protein synth in this vaccine, since you're using mRNA its basically just the blueprint to make the protein. This protein that is made is the spike protein of the vaccine.

The quoted afterglow of https://en.wikipedia.org/wiki/GRB_080319B had an absolute magnitude of -38 for a (very) short time. What kind of mechanism could even account for this? Other claimed GRBs have reached near this level and likely a fair few are currently missed as apparently they are seen in wide wavelength ranges.Brightest stars have magnitude -10 or soThe milky way galaxy as a whole has magnitude -20.8Big elliptical galaxies can go to -233C 273 quasar is ~ -27The brightest/most powerful quasars observed about -32This blazar OJ 287, modeled as a of a 150million mass black hole going periodically punching through an accretion disk of a 18 billion mass black hole generates transient flares of -28 to -29So how can a jet from a collapsed star become a million times brighter than a giant elliptical galaxy or 1000+ times brighter (in the optical in this case, but in general as well) than the brightest quasars, which are super massive black holes with several solar system wide accretion disk. It (the grb) was even potentially just visible to the naked eye for a while from ~ 2billion parsec. Even if it was for only a minute or so.Is it even known with good confidence levels that this was an 'afterglow' of a gamma burst from a star? Does anyone know if there is even a working limit in the models in terms of brightness that these things can reach? What the chances that it is instead something else (although no idea what it could plausibly be...)? Does the spectra or other observations/models rule that out?
OP again... after a few drinks, but not that many.seems to be a few different hypothesis on the main idea and depends a lot on how the jet/beam angle is calculated where smaller angle = more apparent brightness from a constant total power output as well as differing relativistic effects. Many here would've known that. But there is agreement on collapsing stars at cosmological distances rather than other closer objectsthis paper, unfortunately no date?, observes that many GRB afterglows have a similar total power output after adjusting for beaming and cluster arounnd 10^43Jhttps://core.ac.uk/download/25306666.pdfBut then this one says that the beam corrected power output of 080319 was at least 10^45J or 10^46Jhttps://academic.oup.com/mnrasl/article/391/1/L19/1124909It gets all very technical for a googling pleb, as well as hypothetical. i haven't seen from google much about the mechanisms suggested that serve up that much energy in such short spans of time. I saw one paper talk about "energy budgets" and some GRBs exceeding "canonical values" which hints at energy limits on certain models. But I've lost that now. The long range burst afterglows are thought to be the initial gamma jet colliding with material in the interstellar (intergalactic?) medium and it then radiates many different wavelengths from x-ray to radio. With lots of relativistic effect due to large lorentz factors. But doesn't seem much like concrete models like radioactive decay of nickel for type 2 super nova. Will have to be something to put out over 10^18 solar luminosity
