no; an excessively male-centric society based on male excellence unironically results in the inevitable destruction of shit like central banking, predatory lending, and currency inflation, thus there is a multi-billion dollar arm of the establishment whose overall mission is to convince men that they're unhappy because they're failures and not because there's a system of oppression enslaving everyone

I've met a lot of extremely smart women, in fact most of the figures and mentors in my life that I highly respect are women because of my industry. That said, they are, in general, very credulous by nature and are not particularly good at divining relatively simple second-order concepts like "why would a car dealership voluntarily buy my car back from me after two years if it wasn't a good deal from them, and am I getting scammed?"

Pythagoras was right and all of modern mathematics is pseud quackery. The only numbers that are useful, and which actually exist in the real world, are whole numbers or numbers that can be represented as a fraction of whole numbers. Literally nothing else make sense. My reasoning?

1. 0 is bullshit. How could nothingness be a number? You violate the entire concept of nothingness. Nothing =/=Something.

2. Let's say I have one long rod and two smaller rods of equal length. I want to figure out the length of the longer rod. So I put the two rods next to it and, oh alright, I see I need to cut another small rod in 3 pieces and put one of those pieces with the two other smaller rods together to equal the length of the longer rod. No matter I can make up a whole new unit after the length of the rods. Let's call 1/3 of a small rod 1 inch, so that the two smaller bricks are 3 inches and, adding these all up, boom! My longer rod is 7 inches. Pretty easy right? Pretty intuitive right? Makes sense in the physical world, right?
>here anon, here is a rod sqrt(2) inches long! For giggles, how many of these can you fit next to the 7 inch rod?
Erm well, at least four, but then I have 1.34314575051... left over? Ok I guess I can add 1 but now... wait... excuse me but WHAT THE FUCK!? No matter how hard you try you'll never be able to find a fraction of integers to represent what's after your decimal point. Excuse me but... WHAT THE ABSOLUTE FUCK!? How the fuck can you ever complete it then!? If it goes on forever like that without becoming periodic then HOW THE FUCK COULD I EVER MAKE UP THE REST!? You can't even take it all away to get nothing when you subtract. WHAT!?
>Excuse me sir but I'd like sqrt(2) apples please!
Ok here is one apple sir, and here is... umm...
Yeah EXACTLY! How the FUCK do you irrational numbers make physical sense!?
>B-b-b-ut what about pi?
22/7. Done.

3. Don't even get me started on those "negative numbers" bullshit..

This is Paracelsus, a hermetic alchemist, or proto chemist; also the greatest natural physician of his day, and a father of mineral medicinals.

He believed he could produce a slave creation, or a familiar of sorts—the Homunculus—by ejaculating into a chicken egg, or worse.

— ‘That the sperm of a man be putrefied by itself in a sealed cucurbit for forty days with the highest degree of putrefaction in a horse's womb ["venter equinus", meaning "warm, fermenting horse dung"], or at least so long that it comes to life and moves itself, and stirs, which is easily observed. After this time, it will look somewhat like a man, but transparent, without a body. If, after this, it be fed wisely with the Arcanum of human blood, and be nourished for up to forty weeks, and be kept in the even heat of the horse's womb, a living human child grows therefrom, with all its members like another child, which is born of a woman, but much smaller.’ 328–329

The original coomer, if you will.

Yes, we already know that IQ isn't very environmental at all (in developed, or Western, countries).
We also know that SES doesn't mediate within-group heritability, either (i.e. no heritability - SES interaction effect for IQ, https://doi.org/10.1007/s10519-021-10080-w, http://dx.doi.org/10.1016/j.intell.2016.02.003).

Voucher studies in Milwaukee, Cleveland, and Washington show that school quality is unrelated to NAEP scores ("Report 12-14 August 2012 Test Score Data for Pupils in the Milwaukee Parental Choice Program (Report 5 of 5) Legislative Audit Bureau," Evaluation of the Cleveland Scholarship and Tutoring Program Summary Report 1998 - 2004 CEEP February 22, 2006," "NCEE 2010-4018")

Murray (2002) showed that after controlling for poverty, parental divorce, and illegitimacy, the sibling with the higher childhood-IQ went on to attain a higher income in adulthood (causality is from IQ to income).

We've also known, since the 1966 Coleman report, that per-pupil expenditure is unrelated to test scores.

“Alien life exists elsewhere. The odds are just too good.”

“But alien life visiting us? No. Impossible. It could never happen.”

Are scientists just retarded?.

“No you can’t come here. We’re off limits. No way no how. Cope.”

It’s fucking weird.

Do scientists not consider successor theories to our own limitations? Do they think our limitations are everyone else’s limitations?

It happened. I was learning and took a sneaky esp view. There was a woman from our group in space in the afterlife. Another soul creation not our own, a male with brute force went up to her, held her down and a female with him ate her in disgust with how immature our group is.
Ate her? what happened? I could see a stream of particles the size of Planck bits stream away out of their backsides and float off in a wirl into the universe. That was nasty and we are all made up. I think they looked through to me, because I would've caused a stir self defending ourselves..

Humans are terrified of being visited and observed for some reason. Which is odd when that’s essentially what religion is. A desperate need to be judged. Validated.

>Why was he so determined to use carbon fiber?
In pretty sure it was because he wanted a bigger sub to fit multiple people for tourism purposes rather than exploration /scientific purposes. I guess they worked out they could make it bigger with carbon fibre somehow. Apparently doing structural finite element analysis on multi layer carbon fibre tube is difficult and more error prone compared to the common solid steel sphere type subs that are used for deep dives.

That was mainly it, so he could run a profitable tourist trips to bottom of the ocean. He also came from a tech-bro Silicon Valley enviroment and wanted to "disrupt the industry". Turns out that doesn't mesh well with ignoring health and safety regulations.

I just pirated the PDF and read it ages ago, Cambells is very popular they might even have in a library somewhere around you.
I don't think it's that important to get the newest version, any version post-2015 should be fine, older ones might skip on a handful of cool new discoveries but you will hear about them in Alberts anyways.
Alberts, the same story, PDF from libgen for me, but it's the most common molecular biology textbook out there so maybe you could nab it somewhere used if you live in Burgerland, I wouldn't worry about it before reading Cambell.

Are bears so smart because they eat all that fish
1 reply omitted. Click here to view.

they eat fish for a few weeks when salmon swim upstream, they don't eat fish rest of the time
>>
>>16928560

>>16928563
1. The Categories
Let [math]\mathbf{T}[/math] be a category representing time intervals (days/weeks of the year).
Let [math]\mathbf{F}[/math] be a category of food availability (Salmon, Berries, Roots, Small Mammals).
Let [math]E: \mathbf{T} \to \mathbf{F}[/math] be the "Eating" functor that maps a specific time to a specific food source.
2. The Salmon Run as a Natural Transformation
The claim is that "eating fish" is not a constant state but a specific mapping.
Let [math]T_{\text{run}} \subset \mathbf{T}[/math] be the subcategory of the "few weeks" when salmon swim upstream.
For all [math]t \in T_{\text{run}}[/math], the functor [math]E(t) = \text{Salmon}[/math].
For all [math]t \notin T_{\text{run}}[/math], [math]E(t) \cong \text{Berries} \oplus \text{Roots} \oplus \text{Other}[/math].
3. The Morphism of Diet
In category theory, if bears ate fish all the time, there would be a natural isomorphism between the bear's total diet and the set of all fish.
However, the user is arguing that the morphism [math]f: \text{Bear} \to \text{Fish}[/math] is only a split monomorphism (an embedding) that exists exclusively during the object [math]T_{\text{run}}[/math]. Outside of that specific temporal window, there is no mapping to the "Fish" object in [math]\mathbf{F}[/math].
4. The Conclusion (Q.E.D.)
The "Smart Bear" theory fails because the product of [math](\text{Fish} \times \text{Bear Intelligence})[/math] only exists in the fiber over [math]T_{\text{run}}[/math]. Since [math]T_{\text{run}}[/math] is a tiny slice of the total year [math]\mathbf{T}[/math], the bear's "smartness" cannot be globally attributed to a local morphism.

You can have claude steelman arguments.
Theres also the option of running several AI with slightly different settings and have them discuss options.
A lot of the arguments are focused on older less capable models. Every 2-3 months their capabilities improve 2x and does not seem to be slowing down. In a few years it seems likely that the average person will have access to expertise that only large companies could previously afford.
Ive seen demonstrations of the newest GPT morels making browser optimized 3d maps of the globe, with no code. In a year, games like runescape could be made, from scratch, no code.
Agentic performance over time is also on the trend line of doubling every few months.
>its just hype bros
>its a bubble
Its going to transform civilization when *an average person can afford the white collar labor output of an entire corporation*. Capability improvements do not seem to be slowing down. Its self reinforcing because the AI also accelerate chip performance design and materials sciences. There are chips coming out soon that can do inference and training at even greater effeciency due to graphene, that and photonics.
