What is with the idea of invasive species? And why aren't human populations considered to be invasive? How come a snail that looks the same as other snails, comes from a similar climate on a different continent, and poses very little risk in the grand scheme of things is somehow dangerous to the local wildlife? But gangs of Nigerians raping and killing British people somehow aren't? Where's the logic?

That implies the intent was extermination instead of exploitation. We know it was exploitation, it's always exploitation. The job was properly done.

That's how we can do the same thing for thousands upon thousands of years and not realize the mistake. You, they, and everyone before them and I are the "future" generations.

It's never a mistake, it's always the same job and future generations will do it over again.

Good news everyone, Arctic ice accumulation is above average for this time of year compared to the average for this century so far. Seems like the global warming doomsday scenarios that so many scientists have been predicting aren't coming true, isn't that great news? I know you're ecstatic to hear it, especially the people who are so concerned about the environment, they should be extra happy to see this good news.

you have no idea how photosynthesis works.

>>16130879
Here you go, retard. Notice how the energy is not stored for billions of years, but is used by the plant to live and grow.

https://en.wikipedia.org/wiki/Photosynthesis
>To use the chemical energy stored in these organic compounds, the organisms' cells metabolize the organic compounds through another process called cellular respiration.
>>
>>16130879
>>16130975
You know what? Fuck it. Let's pretend that plants violate thermodynamics and store all of the chemical energy they photosynthesize for billions of years.

https://en.wikipedia.org/wiki/Photosynthetic_efficiency
>5.4% net leaf efficiency.
So if you covered every square in h of the Earth you would still have 94.6% of the energy of the sun.

>Photosynthesis increases linearly with light intensity at low intensity, but at higher intensity this is no longer the case (see Photosynthesis-irradiance curve). Above about 10,000 lux or ~100 watts/square meter the rate no longer increases. Thus, most plants can only use ~10% of full mid-day sunlight intensity.[6] This dramatically reduces average achieved photosynthetic efficiency in fields compared to peak laboratory results.
Oh wait, that's more like 99.46% of the energy from the sun. And that's if all the land and sea were completely covered with photosynthetic mass. Even if photosynthesis worked the way you think it does, which it doesn't, photosynthetic efficiency is so low that it doesn't matter anyways.

previous thread >>16072199

if you love stats, weird numbers and counterintutive science, this is your general. Because one of the things with statistics is that nothing ever seems to be what it tries to show you on a first glance or glimpse. Doesn't matter if you are a seasoned professional, NEET or some disgruntled grad student. All are welcome.

Some people may not like it if you try to make them do your homework, others won't care and will just help you. Let's discuss theories together, ask questions and try to meme a little about this field.

in the previous thread we discussed why Julia has promise but is not delivering. How some people still use Matlab but hate it.

So, grab your favorite statistical software, dust off your textbooks, and join me in this exciting journey through the world of /psg/ - Probability and Statistics General! Let's embark on this adventure together and unravel the mysteries of data one statistical concept at a time.

Academics are literal hivemind charlatan scammers. This has been known by many already, but now there's hard evidence to prove it. So-called "experts" are cheaters and liars just like the average student who cheats on his or her exams. And the evidence focuses on STEM papers specifically, including medicine, and not what are considered bullshit majors where of course everyone is expected to be a bullshitter and plagiarizer.

tire wear was calculated into the equation

he noted that the tires of EVs, due to their added weight, will also emit more microplastics into the air

particle pollution from EVs can also increase the risk of health problems,

You are a ridiculous baby if someone not eating what you eat makes you so angry.

There was a thread about this earlier, but for some reason the jannies deleted it.

Apparently, it has be discovered that one of the top stem education scholars in the world, Stanford professor Jo Boaler, has actually been manipulating and fabricating her research for years. This is a major problem because she is literally one of the top scholar in her field and she is literally at the forefront of neoliberal DEI initiatives and her work is currently being used to completely redesigned the entire grade school stem education system in the state of California. She advocates for standardizing education, eliminating advanced STEM courses and electives, eliminating magnet programs and forms of self-directed and personalized education, and standardizing all curriculum and course requirements. She wants ALL public school students (but NOT private schools) to be taught the same material, in the same classes, using the same textbooks, and she wants to discourage independent study or exploration of other topics until students reach the university level.

The rationale for this is that people like Jo Boaler want all children to be on the same page, and they don't want some children having an unfair advantage, and that also want to discourage the misconception that education is about intellectual exploration or "doing your own research". Instead, the goal of education should be to cultivate "informed citizens" who know to seek out and rely on authoritative sources.

Its funny, because 20 years ago standardizing education and eliminating electives and magnet schools and advanced STEM class was considered a conservative policy. At the time it was called No Child Left Behind and it was a policy of the Bush administration. Today it's the neoliberal left pushing for the standardization of education instead.

The jannies on sci have been getting more and more zealous over the years. This board is dead at this point, though, so it doesn't really matter. Power tripping jannies unironically think they're making a difference, and helping "the West" to fight conspiracy theorists/Russia/antisemitism/radical Islam/etc., but nobody even uses this board (largely as a result of their own faggotry), so all of their effort to combat Trump, Putin, the antivaxxers, and Hamas is for nought.

This board used to be filled with dozens of autistic chuds who spent their free time shitposting about graduate level mathematics and the arguements for and against race realism. Now sci is a bunch of transgender Ashkenazi undergrads constantly complaining about troglodyte polchuds supposedly ruining sci, and putting an end too all of the deep, profound, and impassioned discussions at the forefront of modern science, mathematics, and philosophy which they claim were taking place on this board before all the chuds showed up (of course, in reality the "chuds" have been on 4chan since day 1, and all the politically correct normies are the ones who are new to the party).
