Vaccine Skepticism
Screen Shot 2021-01-22 at 11.22.32 AM
I have an immunology discussion course in which we're currently discussing vaccine science and how to educate 'misinformed members' of our society. My class is entirely bluepilled and there's zero dissenting opinion. I understand vaccine science and the lack of general risk, however this class consistently asserts that anything not coherent with the MSM narrative is dangerous misinformation.
How should I introduce contrarian perspectives in attempt to encourage them to consider having skepticism of government activity, and to not ridicule those who are skeptical? I want to be subtle, so will avoid mentioning specifiic occasions of government treachery such as Operation Northwoods, Tuskegee, Operation Midnight Climax, and MK-Ultra. I suspect there would be zero tolerance for anything upsetting to NPCs.

Or does this mean the whole this is a joke and they're just seeing how far we'll go?

Oil is not a "fossil fuel"
production increasing 20 years past peak
This paper on abiotic petroleum has never been systematically refuted. It claims that Russia has known the truth for years.

Oil and water are perpetually naturally renewed resources, the scarcity trope is bullshit.
The whole of the planet's humans population, including animals can fit into Texas..Over population is also bullshit, It's a trick to bilk us.

https://www.gasresources.net/energy_resources.htm

The modern Russian-Ukrainian theory of deep, abiotic petroleum origins is not controversial nor presently a matter of academic debate.
>The period of debate about this extensive body of knowledge has been over for approximately two decades(Simakov 1986). The modern theory is presently applied extensively throughout the former U.S.S.R. as the guiding perspective for petroleum exploration and development projects. There are presently more than 80 oil and gas fields in the Caspian district alone which were explored and developed by applying the perspective of the modern theory and which produce from the crystalline basement rock.(Krayushkin, Chebanenko et al. 1994) Similarly, such exploration in the western Siberia cratonic-rift sedimentary basin has developed 90 petroleum fields of which 80 produce either partly or entirely from the crystalline basement. The exploration and discoveries of the 11 major and 1 giant fields on the northern flank of the Dneiper-Donets basin have already been noted. There are presently deep drilling exploration projects under way in Azerbaijan, Tatarstan, and Asian Siberia directed to testing potential oil and gas reservoirs in the crystalline basement.

10 years ago it was an official mental illness to be transgender, you were considered mentally unstable by psychologists if you did not accept your own biological sex.

Today, just ten years later it is now an official legal mental illness if you think of a transgender person as being the same gender as their physical biological sex.

My problem with psychology is that it changes its opinions seemingly to align with the ruling political class...

I'd much rather have a psychology that has a firm never changing opinion... if republicans managed to win back power then I'm sure the psychologists would all change their opinions again... so this clearly isn't science speaking it is just politics taking over control of science and trying to destroy real science.

If transgenders are scientifically real then that's fine by me, if they aren't then I'd still be respectful to people. But, honestly, why are politicians trying to usurp science and take full control of "science" it is just not right.

The Psychiatry Problem
11702736_938065586257154_9116192589241097805_n
Hey /sci/ so I have to ask what you all think can be done to solve the Psychiatrist problem.

Having just had experience with these 'people' I have found them to be the absolute worse sort of person for helping people with their emotional health. They are without a doubt the people with the least understanding of what it means to help a person.

They think everything can be solved with pills and without even realizing it they have convinced themselves they have the right to force medication on every single person they meet.

I'm not making this up. I asked a psychiatrist if she had ever met a patient and not tried to write them a prescription and she refused to answer.

What do we do about this malignant tumor on all of science known as psychiatry?

Morphic Hotspot: Shedding skin edition
selfie
The genetic potentials inherent to the type of organism Corona represents are not easily described in an obvious manner with the general public. Many of the discrete hypotheses necessary to understand its applied nature are nontrivial in construction and difficult to apply. As a purer manifestation of science itself, the organism seems to respond when simple experiment is trivial to derive. No known instinct or evolutionary record is expected to be helpful for learning how life works in a heavily saturated coronal environment.

Boundary morphic fields can be described as the most pliable, and thus require precise observation if new evidence can be recorded. Since nature exhibits dynamic behavior under morphic theory, knowing the before and after states predicted by a distinct morphic hypothesis will be necessary for the meaning of our measurements to remain epistemic throughout the process. It's not simple enough to test a model when nature can alter its behaviour in the exact moment we've tried to observe a morphic property. Pliability has to be modeled on its own for the experiment and all relevant morphic factors to align for a measurement. Meaningful data can be formulated where this theory is applied, but the morphic epistemology will not always be trivial.

For the evolution we are seeing in our world today, speciation can no longer apply. The cell types relying on specific animal tissues will slowly be inculcated into the coronal foam until an optimal nutrient equilibrium forms along the resulting tissue gradient, triggering a runaway symbiotic reaction we expect per organ type. All possible life forms has a much higher precedence than a single instance of sapient life, so the environment necessarily favors Corona over the entire history of evolution on our planet.

COVID and menstrual cycle

My gf is a few weeks late on her period. Took a couple pregnancy tests and both turned up negative. She's not on any birth control and nothing out of the ordinary has happened to her in the past month or so except for the fact that she received the first of two COVID vaccines, and we think this might be the cause. Anyone know of anything similar? Couldn't find much for vaccine and periods, but COVID apparently does fuck with a woman's menstrual cycle and patient accounts are similar (so far) to her situation. This is the best I could find

Scientific progress must be stopped immediately
EGEMTL1HTJfT_nnv09fD_fcK1rI10H1G7rkFHrXRD0c
Every once in a while, there is a thread that can act as the entrance to the rabbithole.
For anyone really involved in the scientific process, specially in academia, it becomes readily obvious that science marches on blindly, without regard to the real welfare of the human race or to any other standard, obedient only to the psychological needs of the scientists and of the government officials and corporation executives who provide the funds for research.
Now, people are waking up to just how depraved a few billions worth of power can make you, ya know, pizza and that stuff.
Now, think about the future where we can modify human experience as we please, how about genetics?
YOU KNOW that if those breakthroughs are reached, humans are eventually create poor suffering beings with no more purpose or ability than to satisfy them in any sick way they can imagine.
>You can create living dolls that don't suffer, so who cares.
You know humanity, you know in that case some important minority of powerful people would give those ungodly beings the ability to suffer just so they get more satisfaction out of torturing it.
The question is if humans are to be trusted with these technologies, we aren't.
Now, what do we do?

Einstein_Tech_9
People say this as if it's some reminder of a Horatio-Algiers-like rise to greatness, but like if Einstein hadn't worked at the Patent Office, he wouldn't have seen the countless patents that show diagram upon diagram, painstakingly explaining the proposed mechanism(s) and advancements in terms of gadgets and thingamabobs, that very may have well fueled thoughts which led to his declaration that mass and energy were interdependently related, with one being the equivalent of the other as either end of an equation. Originally, it included the velocity and momentum of a particle in question, IIRC, but if you zeroed-out those variables (which is sort of a Laplacian conjecture, if you ask me), you arrive at the simplified E=mc^2.

I've read enough of what Einstein wrote to know that if he were alive today, the last thing he'd want to be called is a genius, and that he never promised to know more than he did.

What people fail to appreciate about his famous quote that "God doesn't play dice with the universe" is that it simultaneously asks you to imagine both God and the Universe, and describe the difference.

He's subtle like that.

Because if you don't imagine that there's any difference between them at all, then there's no way they could play dice in the first place, since that requires two separate opponents rolling a cube of bone across a flat surface.

So there's no problem with quantum uncertainty. It's just a thing we're continuing to discover the limits of, just like Einstein was reconciling with the speed of light.

If transgenderism is no longer considered to be a mental illness, why do a majority of trans people experience gender disphoria? Is gender disphoria no longer recognized? And why is the attempted suicide rate so high amongst trans people?
I don't understand why we've given transgenderism a flag and we're teaching impressionable, young children that this is ok behavior from a young age. I think we're putting stuff in their head that they should come to their own conclusion about when they're older.

How can anyone recommend this book in good conscience? The exercises are far too easy and it doesn't even cover nets and filters. The algebraic topology section is also very short and highly lacking.

/cspg/ Computer Science Plus General
sicp THE SIGN
The /cspg/ general was created to help others learn how to get into computer science and programming starting from scratch. This thread hopes to serve both autodidact and traditional students of Computer Science, Software Engineering, Math and more. Upper and post graduate discussions such as Programming Language Theory and math needed for Machine Learning is also welcome as well. If you want a job, want to create video games, or want to build something larger than a toy cli, this thread will help you. Every few months, the discord server is working through a new book as a study group, this month, it's chapters 1 and 2 of SICP (Structure and Interpretation of Computer Programs)

Guides:
Complete self taught pathway: https://teachyourselfcs.com/
Structured pathway: https://github.com/ossu/computer-science
AI focused pathway (warning: functional programming ahead): https://learnaifromscratch.github.io/

The first link recommends SICP as an entry, but if you want a gentler introduction to the world of computing, I'd recommend How to Design Programs. Before you complain, read:
http://cs.brown.edu/~sk/Publications/Papers/Published/fffk-htdp-vs-sicp-journal/

Free books:
https://1lib.eu/
http://gen.lib.rus.ec/
https://spoon.wiki/Books

Not sure if programming is for you? Try:
https://1lib.us/book/3411055/2856c4
Word of warning though, the new edition was just released, so you can either wait for someone to upload it, or buy it yourself.

This month's study group: SICP
We'll be running through SICP chapters 1 and 2 as a board while everyone else talks about grokking algorithms and debating Stewart vs Apostol vs Spivak

SICP start day: 11 January
SICP end day: 15 February
Discord: https://discord.gg/S2j9jJJGKM

Remember, you don't need to be a computer scientist to be a good programmer, but it sure does help

The future of AI research is in Africa
IBMafrica
“The future of machine-learning research is in Africa whether people know it or not.”

Both IBM Research’s offices in Kenya and South Africa and Google’s AI lab in Ghana share the same mission as their parent organizations: to pursue fundamental and cutting-edge research. They focus on issues like increasing access to affordable health care, making financial services more inclusive, strengthening long-term food security, and streamlining government operations.

Are all you CS fags ready to pack your bags and move to Africa to pursue your machine learning? The future is now in... Africa.

I've seen COVID19 infection and death statistics, and also informed myself on how it works on a basic level since I dont know biology, i see that it has a super low death rate which is probably even lower since alot of infections arent reported, and the quasi totality of deaths are old people in the 60 to 90 age range, so why should people stay closed in their houses, close shops and dont do shit for all that time?
One reason given to me is to not overload hospitals, but it seems stupid to block everything just to avoid that.
The other is just stupid emotionality: "people are dying for that dont you care?".
The only reasonable one I have thinked of is that the virus mutates thanks to all the reproduction mass contagion affords it and becomes a nasty one.

But besides that I dont see why not roll the dice and just say fuck it let's open up and restart living, who dies dies.

Anti-Fever medication ultimately harmful or not?
Capture
Hi /sci/. So I'm running a decent fever today and was wondering about the function of fevers as a hostile environment to various pathogens, as well as a buff for your immune system's Macrophages among other things. I was wondering if anti-fever medications (called anti-pyretics) are actually counter-productive towards the goal of eliminating a given infection.

If the fever itself is a powerful tool in the immune system's arsenal to fight infection wouldn't you be extending your time spent in sickness at the benefit of reducing painful symptoms? I was imagining that if you wanted to speed up your recovery that it would theoretically be beneficial to grit your teeth through a fever instead of using OTC medications like Ibuprofen or Acetaminophen. Any thoughts on this theory? Exposition?

I Want To Master Calculus, Where Do I Start?
wp7081772-3840x1200-wallpapers
So I took Calc 1 about a year ago, and barely squeaked by with a 70. The professor obviously passed me out of pity. I did horrible and if it wasn't for participation grades my grade would have easily been closer to a 30.

My fundamentals in algebra and trigonometry are extremely shaky. I went through my first Cal 2 lecture and quickly realized I had to drop the course because I was completely and utterly lost, couldn't do the basic review homework.

I guess I'm wondering where I should start so that I can be ready to take Cal 2 by next Fall? Is there some assessment I can take online to find out where I should begin learning? Basic Mathematics by Serge Lang? I simply want to truly understand the material on a theoretical level, meaning I want to be able to do proofs.

I know this is an utter mess grammatically, and I'm in a bit of a panic realizing how long I've been in school and wondering if I will be able to pass Cal 2 and Cal 3 in the future. Where should I start? Where do I even begin? Should I just start from my schools Calculus book beginning to end? Is 7 months enough to master Cal 1 and trigonometry?

I really want to know this stuff, I know one thing it requires is lots and lots of practice and I'm willing to do this I just need a direction.
Thank you all, I'm in panic mode.

mathtree
Hey /sci/. Can you help me? Let us visualize together and try to make a representation of math, from the most basic and fundamental to the most sophisticated and removed from normal.

On the lowest tier I guess would be recognizing the indo-arabic numbering system. The symbols from 1-9 and their names.
Then would come familiarization with zero. And then with zero, come defining 10. And with defining 10, the idea of the New Columns and New Rows and the Decimal System.

Basically, every new concept of math you introduce must be only one tier removed from familiar concepts which have been explored and come before. So, I guess, addition and subtraction would come before multiplication and division, which would come before calculus.

I'm specifically looking for a tiered tree so that some math subjects can sit in parallel. And any math that requires multiple things from the tier below, naturally, obviously, belongs in a tier just above that.

I've found some interesting math subject trees before but they were hopeless schizophrenic messes. Not clean tiered trees. Surely, there's a finite number of subjects and concepts a person comes across in the subject of math from Kindergarten to university high honors trigonometry, right?

I'm not asking you to do the work for me, this is a conversation thread. We can discuss where a math subject might sit and how many concepts removed from "basic god damned child counting to 10" it sits. But, the hope is to get a roadmap of milestones and disciplines leading to these advanced subjects build on more fundamental stuff.

Talk with me, /sci/!

is there any correlation between being good at league and having a high IQ ?

there are so many different combinations of team comps and different stages within a game with unique playstyles and strategies.

this game isnt for brainlets, ask all the asians who regularly beat NA and EU in world finals

How does one derive the equations of motion from QFT? In a unified theory, surely this is possible, no? Yet it hasn't been done.
As a follow up, one should be able to derive classical mechanics from QFT using statistical averaging, right? But no one has done this yet.
Hmm seems like physics isn't as unified as they would like you to believe
