Unlike what everyone says, maths isn’t a pure discipline. Axioms exist because they help us do stuff in the real world, they are as practical as physical laws. The myth of the mathematician that makes up his own flavor of maths just for the sake of it is just plain cringe.
What does this have to do with the post? Wildberger is free to choose any set of axioms makes his penis hard, but at the end of the day if his results don’t help us in any way in the real world it’s just an academic circlejerk for people with a lot of time in their hands.

>>12796550
Not so. Whether he's right or wrong teaches anyone who studies him and the problem more about logic and reason. Those people will be more accurate or less likely to make similar mistakes in the future.
Plus it helps in the fact that once people come to a better agreement and understanding of the solution, they'll move on to something else. All that wasted time you referenced will go to the next thing that could help human understanding.

If we struggle to make enough vaccines for North America, imagine making 7.8 billions doses (assuming it's the J&J vaccine that requires just one shot for everyone) every year. Assuming we are not going to retool the current vaccines for the current and future variants.
>inb4 muh taking over production for war-like productive effort
Vaccine production facilities are not like the fucking strategy games builings where you orders a few NPCs to hammer on a certain point of the map until a factory is ready, you need to organize, buy machines, hiring and training specialized workers who are not infinite. We will always have a production cap.

This shitshow will not go on forever, I think it will take 2-3 years before people realize that this is the new normal

I say we just let the virus wipe out all the boomers so the rest of us can actually get back to our lives. It will be penance for all the shittiness those self centered assholes have inflicted on this planet

Female monarch in the U.K. can probably identified as an inflection point. Keep in mind that trend reversal can take a while to become visible after an inflection point. Female monarchs are part of the Satanic agenda and so is the femism that female monarch inevitably promote, and all the rest of the bullshit that gets swept up in, "If femism is ok then why isn't X ok too?" Femism is not ok. That's where the line should be drawn.

Women are most attractive in the 35-45 range courtesy if their experience, careers, and maturity.

There was no study, shit's made up.

>>12795511
>It seems to have data reminiscent to your image, just way more coarse.
Thanks for posting this. Yeah, this is what real data looks like. The OP graph I posted is too smooth to be real data. Reading your study, it seems each age bracket only consists of 3 people. This makes it very sensitive to a bracket having only ugly people by chance (as seems to be the case for 30-39, for example).
>I don't know if your data is legit or not, but it seems that you at least shouldn't discard it outright.
I suspect the data is bogus. But I don't discard the idea behind it, in that peak female attractiveness probably is before 18. There are many other indicators that this is the case. I doubt that the peak is 13-14 though, or that 11-year-olds are as sexually attractive as 29-year-olds on average. (Oddly, your source also has 10-14 as the peak...) Which is why it would be interesting to see real data.

>>12795343
It make sense back in the day we used to marry young girls

14 y.o. have the peak female body, many having already fully developed physically so it's all downhill from there. Their mentality is mostly early teenager though, no doubt about that, and I guess that's why some zealous countries like the US love the idea of a strict and very high legal age such as 18.

>>12795573
Leibniz came up with a few mathematical things first and or better, but the theory of gravity, the other physics was Newton alone.

>>12795604
This.
Barrow and (unknown to Newton), Leibniz deserve some recognition on some of the math, but the physics is all Newton.

A ton of CS majors only take numerical linear algebra. Similar to how they take a dumbed down discrete math class often called discrete structures.

I don't know how much of a brainlet you have to be to struggle with linalg. You can always easily visualize this shit with 3D vectors and rotations/stretches as transformations, even if you're working with complex continuous Hilbert spaces. All this shit is easy to generalize. There are very few times when this approach doesn't work.

Given that the study of organometallics has only been around for about fifty years I'd say it's a good field to get into. A lot of things have yet to be studied.

>>12795261
Yes, a general factor of intelligence exists but the variance in IQ between people can be explained entirely by environmental factors, Childhood nutrition, Socioeconomic status, school quality, and so on. Absolutely nothing happens in the factor analysis process to tell us about what the causes are for people having different measurable levels of intelligence. And even if we accept a single general rule exists, that would not necessarily imply genetic causation.

>>12795756
>It's all due to 300 years of racism, oppression and poverty

>70,000 years of evolutionary divergence played absolutely no role whatsoever

>>12795280
it's actually more than half with IQs below 100. more like 65% or so. IQ is normalized to european populations.

>>12795261
Okay average IQ differences are settled, how about distribution or stdev differences? Is the white distribution wider with more genius and retardation than in asians? Does african distribution skew positive to stay clear of 0?

you're right, i should've done my research/attended open days earlier. still, applications for accommodation are only just opening and i don't think most people have picked their firm/insurance choices yet

>>12795344
don't applications for accomodation come AFTER acceptance letters?

>>12795467
no, applications for accommodation are open now but you don't get accepted to the uni you applied for until you do your A levels because you need to meet grade requirements to get in. although if you don't meet the grade requirements for your first choice uni then you have to apply for accommodation for your backup choice (or through clearing if you don't make your backup choice either) in the summer, by which point the best accommodation has already been taken up

>>12795562
best accommodation is off campus
you get to learn tricks from 2nd & 3rd year students and you still get to fuck freshers if you have social skills.
if you don't, living on campus won't help shit.
but, aren't all degrees online now? how's that work?

>Contrary to widespread views—based mainly on anecdotal evidence—level of education, occupational status, or use of contraceptive pills does not seem to have a profound influence on the number of births. In fact, the evidence suggests that the extensiveness of kinship networks and the degree of the relatives’ assistance with childcare are most strongly predictive of fertility in the Gypsy population. Our data proved to be highly supportive of the evolutionary hypothesis that personal services through kinship networks are particularly valuable resources, accounting for the higher fertility in more traditional societies compared to technologically more advanced ones.

>>12795197
Sounds very interesting.
This is like a very strong scientific link instead of buzzword links like education and wealth causing low birthrates.
