the "mengele" that you know is a character from a newspaper serial

the real mengele was just a boring hospital administrator not some urban legend creepypasta mad doctor

I'm creating this thread here because I don't care about what humanities fags think:
Is there a school system where kids can test out of certain classes if they already know the subject? Let's say your kid has already learned trigonometry at home (totally doable), is there a system in which he can do a test(s) showing he already knows the subject and therefore skipping that class instead of wasting his time with it as if school was fucking prison?
Obviously homeschooling is the most flexible system but it makes it harder for a kid to be surrounded by more competent peers, which is a big motivator to study more. I've acquired the perhaps mistaken impression that IB (International Baccalaureate) schools offer some of that flexibility

That concept (if I understand it correctly) doesn't exist in my country, which is Switzerland, which has that multi-track system you might know from Germany.
Only like 30% of people attend the track that preps you for a college-requiring education.

I did not attend that track, because school here is only mandatory to 9th grade, and I made use of that and did not continue further. I attended secondary school for adults (i.e. evening school) a few years later, so I go to university now coming from a non-orthodox path.

Secondary school was a breeze; in uni, I study math, which is PRETTY challenging, CS, which is moderately easy, and philosophy, which is honestly so easy it puts me to sleep. I'd prefer if the lecturers and subjects could advance at 3x the current pace. For most philosophy, I just need to read a short summary about the author's thoughts and I can already home-in on what they mean, and reconstruct their thinking process, with 90+% accuracy.

The average IQ of a college student has fallen by 17 points over the past 85 years

https://www.frontiersin.org/articles/10.3389/fpsyg.2024.1309142/abstract

>Meta-analysis: On average, undergraduate students' intelligence is merely average

According to a widespread belief, the average IQ of university students is 115 to 130 IQ points, that is, substantially higher than the average IQ of the general population (M = 100, SD =15). We traced the origin of this belief to obsolete intelligence data collected in 1940s and 1950s when university education was the privilege of a few. Examination of more recent IQ data indicate that IQ of university students and university graduates dropped to the average of the general population. The decline in students' IQ is a necessary consequence of increasing educational attainment over the last 80 years. Today, graduating from university is more common than completing high school in the 1940s. Method. We conducted a meta-analysis of the mean IQ scores of college and university students samples tested with Wechsler Adult Intelligence Scale between 1939 and 2022. Results. The results show that the average IQ of undergraduate students today is a mere 102 IQ points and declined by approximately 0.2 IQ points per year.

Did more research and found some studies that examined doses within 5000iu and 50,000iu with positive outcomes. I took 5000iu today but tomorrow I'll start loading with 20,000iu for a week then go down to 10,000iu.

I also went ahead and got holy basil as well. I started taking it today and the only thing I've noticed so far is that I'm urinating much more often than usual. But hoping that this will all help, or at the very least the placebo effect will work on me.

11 textbooks to study math from, to make you smarter. Use WolframAlpha or Symbolab to check your answer if you have difficulty for [2-11].

[1] Linear Algebra Done Right by Axler: Do this first, it's free on his website, teaches you how to read and write proofs in linear algebra, makes understanding "pure" math easier, 800 problems, majority of mathematics programs in the USA use this book.
[2] Calculus with Applications by Lax: It's a compact comprehensive introduction to single variable calculus, that has 400 problems. No prerequisite needed.
[3] Ordinary Differential Equations by Logan: A compact comprehensive overview of ODE's, that is used in multiple universities in the USA, prerequisite is [2].
[4] ISBN 3030263835: Optional, prerequisite is [3].
[5] Multivariable Calculus by Lax: Only 400 problems, for most...learning math ceases after [5], unless you are a physicist or electrical engineer. Prerequisite is [2].
[6] Partial Differential Equations by Logan: Similar in style to [3], prerequisite is [5], 300 problems, problems start to require a whole page of work or more.
[7] ISBN 3031487834: Optional, prerequisite is [6].
[8] Complex Analysis by Eiderman: Every problem contains solutions, has 200 problems, prerequisite is [5], is a great book to learn from.
[9] ISBN 0470054565: A more difficult, optional alternative to [6], yet is more comprehensive. Realistically...for most...prior experience is required, such as that found in [6].
[10] ISBN 0486406784: A cheaper older companion to work alongside with, or optional alternative to [3]. This is 224 pages while [3] is 384 pages.
[11] ISBN 048666158X: A cheaper older companion to work alongside with, or optional alternative to [6]. This is 192 pages while [6] is 300 pages.

As you complete a math textbook, you become smarter, therefore making the successive textbook quicker to complete. If you're working full time, it would take you between 3 to 12 months to complete each book.

"Terse" is the wrong word, but it's a short book divided into many short sections, so occasionally I felt like there wasn't much to look back to if I was stuck on an exercise. However, it's a fairly easy book that does a good job introducing things like topological notions and formal definitions for limits and derivatives to students that haven't taken real analysis yet, which sounds like what you want.

So...if I completed this book, would i meet the prerequisites to work through and understand for the most part complex analysis by Lang, because that is the main goal for me.

Basically trying to bypass real analysis, by doing complex analysis first then real analysis
>>
>>16100097
Lang is harder and it expects you to have some familiarity with undergraduate real analysis:
>We assume that the reader has had two years of calculus, and has some acquaintance with epsilon-delta techniques. For convenience, we have recalled all the necessary lemmas we need for continuous functions on compact sets in the plane.
This makes sense, because it's intended as a graduate-level text to begin with. Brown & Churchill mostly cover the topics in the first half of Lang (at a lower level of difficulty), so I think it's a reasonable introduction to complex analysis before you start Lang, but I would advise you to also learn some real analysis somewhere inbetween. I'm not sure why you'd want to bypass real analysis as a non-engineer anyways, it's a natural foil to what you learn in complex analysis.

visual complex analysis by needham is great

>>16100188
>I'm not sure why you'd want to bypass real analysis as a non-engineer anyways, it's a natural foil to what you learn in complex analysis.
It's because some people have said that their first analysis course was complex analysis, as opposed to real analysis, which is what the majority of mathematicians go through first in order to learn analysis.

I'm still trying to find the book that they are referring to on amazon, it's the strangest thing. Maybe if someone wrote a complex analysis that was as good as linear algebra by axler it would work for everyone.

Does anyone here know what kind of caterpillar this is?
12 replies omitted. Click here to view.
>>
>>16100311
>Yes, that narrows it down a bit. In Central Florida, you might encounter various species of caterpillars. Given the region, this could potentially be a caterpillar of the genus Lonomia, or it might be one of the various tussock moth caterpillars, like the fir tussock moth caterpillar, which is common in the United States and often found in urban areas. However, it's important to note that caterpillar identification can be quite complex, as there can be significant variability even within the same species. To get a precise ID, a local expert or an entomological guide for the region would be the best bet. Always be cautious as well, some caterpillars have urticating hairs that can cause irritation or allergic reactions.
Which one do you think is most probable given what you see in the picture?
>Based on the photograph and the location you've provided, the most probable identification would be a tussock moth caterpillar. They are quite common in many parts of the United States, including Florida, and are known to inhabit urban areas. The tussock moth caterpillar in the image seems to have dense tufts of bristles, which is characteristic of these species. However, a specific species identification would require more expertise and possibly a physical examination. If you need to handle it or are experiencing issues with many caterpillars, it would be best to consult with a local extension office or entomologist.

Of course, take this all with a grain of salt. I just think it's cool GPT4-sama can "see".

It's all interpretation. Lutheranism was founded because Martin Luther interpreted passages of the bible differently. Same thing with every other branch of Christianity.

The Hasidim were formed because of a differing interpretation of the Talmud. I would say that their interpretations of all the other Jewish holy books are a lot closer to how the Talmud is supposed to be interpreted. Also the Hasidim are a lot closer to what Medieval Judaism was like.

North American grey squirrels have taken over England and wiped out the native red squirrel population. This demonstrates that the two populations can't live side by side and that if greys are permitted to encroach the reds will eventually be eliminated.
The greys now have a toehold in mainland Europe and are rapidly expanding their territory at the expense of the reds.
Should grey squirrels be holocausted in Europe in order to preserve the native red squirrel population?
Should the greys be exterminated in England in order to return the reds to their natural and rightful homeland?

As the global pandemic unfolded, government-funded experimental vaccines were hastily developed for a virus which primarily killed the old and fat (and those with other obvious comorbidities), and an aggressive, global campaign to coerce billions into injecting them ensued.
Then there were the lockdowns - with some countries (New Zealand, for example) building internment camps for those who tested positive for Covid-19, and others such as China welding entire apartment buildings shut to trap people inside.

It was an egregious and unnecessary response to a virus that, while highly virulent, was survivable by the vast majority of the general population.
Oh, and the vaccines, which governments are still pushing, didn't work as advertised to the point where health officials changed the definition of "vaccine" multiple times.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9975718/

https://www.statista.com/statistics/1191568/reported-deaths-from-covid-by-age-us/

https://www.cdc.gov/obesity/data/obesity-and-covid-19.html

Tucker asked Kory why the people who claimed the vaccine were "safe and effective" aren't being held criminally liable for abetting the "killing of all these Americans," to which Kory replied: "It’s my kind of belief, looking back, that [safe and effective] was a predetermined conclusion. There was no data to support that, but it was agreed upon that it would be presented as safe and effective."

Carlson and Kory then discussed the different segments of the population that experienced vaccine side effects, with Kory noting an "explosion in dying in the youngest and healthiest sectors of society," adding "And why did the employed fare far worse than those that weren't? And this particularly white collar, white collar, more than gray collar, more than blue collar."

>Kory also said that Big Pharma is 'terrified' of Vitamin D because it "threatens the disease model."

10 trillion dollars exchanged hand.

The biggest corruption handout happened where donors got paid by politicians. Where millions died.

You're told that we have "no idea" the origin of the artificially created lab virus. You're told no one knows who funded the creation of the artificial virus. You're told that the vaccines works, yet the data to back up is censored/removed and if you ask for sources, you are told that you're a conspiracy theorist for not believing what the government told you to believe.

Oh and on top of that, millions lost their jobs, tens of millions of children lost 2-3 years of their education, country's economy was shutdown for those years, everyone asking questions were told that they shouldn't question authority.

Did you castrate your brain that much?
