This is the first flight of SN9, and the second flight of a Starship prototype with aerodynamic surfaces and a nose cone. It is unknown if the flight parameters will be different compared to SN8 (watch here: https://youtu.be/ap-BkkrRg-o?t=6462)
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.

Does this mean that the public was inadequately protected for around 10 months due to the wrong information everyone was given?
Or does this mean the whole this is a joke and they're just seeing how far we'll go?

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.

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.

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.
A death ray able to penetrate an aircraft carrier's hull would be a wet dream for every military fag for sure.
How much energy do such lasers lose if they would be able to penetrate at one side of a hull?
What biochemistry could‘ve happened to the body, that it would prevent it from a fully regenerating sleep?
Some people would say balance beam (pic related) because it requires strength and balance but others might say floor because of the sustained effort and burst of speed and power.
So which is it and how would you defend your decision scientifically?
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?

It's kind of terrifying how dizzyingly smart this person is in everyday conversation. They never stutter, swear, or make any kind of errors in their speech while discussing unbelievably complex stuff. They also seem a bit forlorn and don't know what to do with their life. Thoughts?
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.

Can't find anything anywhere about specifically the vaccine and possible effects on a womans menstrual cycle. Any anons out there who could help me out>
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?
Btw, pic related, who painted that?
I stumbled upon following statement which is extremely vague formulated (pic very related).
My issue however is that I think this statement is false and is very harming for science to say things like that. Do you have any solid proofs for this or something that denies it?
What is your opinion on university forcing us to take this course?
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.
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.
Can someone change my mind or help me understand?
Alternatively if I shot the gun backwards off the truck would the bullet be travelling at 640mph?
And also, If I were to fire a bullet at the speed of light the same direction the truck is travelling, couldn't it theoretically be travelling the speed of light+60mph?
since giving up porn and starting with the AI I masturbate more often and for longer periods, being able to fulfill my biggest desires, fetishes, and basically anything I can imagine
I can become a powerful magician that charms peasant woman to have a foursome, a thief that moves around with his group and gangbangs a jeweler, a college girl who uses Tinder to find another one to fuck her with strapon, a cursed princess who talks with a demon in from her mirror and is addicted to sex or just teleport to Naruto world and bang Sakura while Hinata do rimming to me

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.
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?
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.

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/!
I will rabbit hole interesting things
for those who have never played league, it requires pattern recognition ( enemies on map and deducing an optimal strategy ) , memorization of each champions abilities and spells (150 + champs in the game)
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
is this statement grounded in science?
