"Why doesn't the preeminence of the US math knowledge appear to seep into the primary and secondary school education?"

Because preeminence of top tier institutions (which are kind of global centres anyhow) - has absolutely nothing to do with teaching math to the commons.

Here's a hint:

+++ Americans don't suck at Math +++

There's a very un-PC but very large elephant in the room that people won't discuss.

+ European American and Asian American 'testing scores' are actually pretty good - and have been holding steady for a very long time. (Asians do a little better). Nothing has changed.

+ Latino American and African Americans fare poorly, but having been getting better since we've been measuring by standards (i.e. 1950's-1970's).

Here's the trick:

+ European Americans actually do better than Europeans - on average.
+ Asian Americans to better than Asians - on average.
+ Latino Americans do better than Central/South American Latinos
+ African Americans do better than Africans.

The key correlating factor here is 'ethnicity'. 'Ethnicity' is the broad, generalist predictor of educational outcomes. This definitely not 'race' and it's not even 'IQ' (those things are plausible but controversial) - it's a series of behaviours, social norms, examples, attitudes towards work, success, access to services, social networks, mentors, role models, etc. etc. etc..

Educational outcomes (and crime stats, income stats) break down along ethnic lines. In a manner of speaking - America can be thought of as 'four nations' - White, Black, Asian and Latino. Obviously - it's very crude and generalist, and policy based on this would probably be racist - nevertheless - you pretty much have to look at the data given this.

In the end: American test score results have more to do with the changing ethnic composition of the American population than they do anything else. Again: White people and Asians in America have performed consistently he same for decades. Teaching methods haven't changed much, students habits haven't changed much - so the outcome is naturally consistent.

More economic prosperity, access to services and different attitudes + deeper integration have meant Latino A. and African A.'s are doing a little bit better - but because there are so many more Americans of those groups - particularly Latino Americans - it changes the outcome of the 'average american test score'.

Analyzing educational results does not make sense until you break it down along ethnic lines. Once you do - it becomes crystal clear. It's the absolute #1 most important thing about the educational data that turns 'paradox' about educational investment (teaching has remained largely the same) and outcomes into 'perfect sense'.

Unfortunately, it's so sensitive few will want to talk about it - for fear that the general public equates educational outcomes to 'intelligence' and try to strongly correlate ethnicity + race to this, which would be fodder for racist/KKK types, which wouldn't really help the overall social situation in America.

Anyhow - America is actually doing pretty well overall.

This is simply bullshit.

Because of the internet people are finally hearing the news without a filter. They are no longer getting news they don't care about or don't want to hear.

So they are actually controlling the politicians as they want. Not as the old news/system told them to.

This is what is actually scary. Having the peoples voices heard isn't the utopia we thought it would be.
Oh dear, we are heading for a recession worse than the last but with even few economic instruments to recover from it and even less political will and stability.
IMO, Mac laptop keyboards have been going down hill since they switched to the chicklet style. I much preferred the pre-2008 MacBook Pros with "regular" keyboards.

"It's an interesting question when you consider that in at least two university mathematics department rankings[1][2], the US holds 7 of the top 10 global spots."

It's a fallacy. US is a large country, so those talented students concentrate in fewer universities. In Europe for instance, due to language and culture barriers, talented students from Czech Republic do not very often go to Cambridge. You need to look at mean or median if you want accurate assessment.

I think it's a very "I can type without looking at my keyboard" centric view. If your keyboard shortcuts are already going unused it may be a discoverability problem, or it may just be that people who aren't power users will always prefer the mouse/track pad. If that's the case then I'm not sure glitzy icons on the keyboard help them.
I once heard an anecdote that might describe some of what's happening. In the trenches of WWI, when it was time to fight, soldiers would have to climb up a ladder onto a battlefield. The problem was that German snipers could see the tops of the ladders. The Germans would keep their rifles fixed on where they knew the enemy would emerge and simply shoot them down once they saw helmets appear.

The European Allied soldiers were so disciplined that they just kept climbing up the ladders and getting killed one by one, following their orders to their deaths. The Americans saw this and said, "fuck that, I'm not climbing up there."

I think most Americans are pragmatic and they won't do something unless it makes sense. And to be honest, most people don't need to study math. Or at least it's not obvious that they do. I think most of the math professors I've talked to would agree. They view math, as it's taught in core curricula, more as an art than as having vocational value.
Most math (and physics) programs, especially at higher tier universities, have not only a disproportionate number of foreign professors and researchers but also students. So it's largely people who had superior primary and secondary school math education teaching others who had superior primary and secondary school education.

You can see this especially strongly in graduate programs, where US citizens can often get a sort of "affirmative action" because they are the only ones eligible for NSF student fellowships (incentivizing universities to admit them). There's just very little domestic interest in math and physics, despite both feeding into rather favorable job markets (as long as you aren't dead set on being in academia long-term).

As for your second question, it's an extension of US universities' preeminent standing in most fields (on average, there are of course exceptions). I don't think there are really any math specific effects going on there.
I would hope that conventional K-12 at some point would include instruction on what a balance sheet is, a P+L statement, and a bit on what the jargon is. Should also include the basics of sales, how a business operates, finance (as you said), etc.

But that hope is in vain :-(
> tuning the students in to Khan Academy and suchlike programs

I think parents have an enormous role to play in the effectiveness of K-12 education. If they are not very much involved (e.g., enforcing, participating, encouraging) then school isn't valued or prioritized, nor will the average student see how fun many subjects can be to learn (assuming the teacher may not be effective at this).

> were taught math badly

> teach it badly

Just an aside, wouldn't this be expressed as "taught poorly"?
Probably CF cards. Most pro-level cameras have that as the primary card slot with some also offering a secondary card slot that is SD. Our cameras all do. The standard slot on regular cameras tends to be SD, though.
It's baffling that they don't require email, or better yet, phone verification before allowing you to tweet. That one simple change would make it a lot harder to spin up alts. On second thought, it's not baffling. I'm sure they're worried it would hurt their user growth numbers.
China is a larger country with extremely promising mathematics scores. So why is it not 8/10 China and 2/10 US (in proportion to population) or even more extreme? A large country having access to a large talent poll doesn't get very close to explaining what's going on.

Even if you think AID's was from the CIA, it's killed less people than biological understandings have saved.
Yes, that's true -- math is not a physical science in that sense. Though as another poster pointed out, theoretical physics is not so different from mathematics in this way, so perhaps the distinction is more between experimenters and theorists. (However, I've no idea what life is like for theoretical computer scientists without any kind of external funding support.)
A couple months ago, another similar fascinating story about frigatebirds was on HN: https://news.ycombinator.com/item?id=12036725

Math is hard work. I was bad at math. I went to college a couple years after I graduated high school where I made little effort to challenge myself. But after figuring things out, at 20 I decided I wanted to do computer science as I enjoyed some of the programming skills I picked up (C++ of all things!).

I was very unprepared for the math part of it and it was hard. I tested into a remedial math level and when I looked at the CS requirement I knew that wouldn't be a good way to start. So I bought a used math book and spent a few weeks studying hard so I could get into a decent math placement so I could be where I needed for CS. This was just the start.

I had a long road with a lot of frustration but I made it. I made it because I never worked so hard at something up to that point in my life. There were times I thought it was hopeless but I just continued to do rote math problems, over and over again. And slowly the concepts started to sink in more and more. But there was always the frustration of missing the little details and forgetting a concept or not having enough experience honing a certain skill. But if I kept at it, over and over again, I would learn it and it suddenly became easy.

I was "bad at math". It would have been so easy to quit and try something else. But I knew I wanted to not only pass my tests but really understand the calculus and differentials, etc I had to do. And it was the best thing I ever did for myself.

Not only does working so hard at something prove you can work hard and achieve something but it shapes the way you see the world.

Math is hard. Some of us just have to work harder. People should realize that failing is normal and if you keep at it you will eventually get it. For some people it takes longer than others. I could never create math. But with enough time I believe I could eventually truly learn anything because of this experience.
> The executive can always modify or repeal the act that defines their constitution and authority.

Um, what? Once it's signed into law (which the acts that empower agencies like the FCC are), the executive branch can't modify the law at all. Only Congress can. The only thing the executive can do is veto a bill when it comes, to prevent it from becoming law in the first place.

I don't know of any country where teachers are considered as elites. The reason your mother took that as compliment is not because teacher is a high social class occupation, but because being good at english is considered a great skill in many countries. If you really had to compare, in most cases people would feel more flattered to be mistaken as a doctor (or an engineer who works at Google than as an elementary school teacher.

I know people will throw stones at me for this, but the reason teachers are not the top 1% of the society is because functionally their job is a commodity. (We're talking about elementary/middle/high school teachers, not professors here).

It is not hard to find someone who knows high school math, for example. I'm not discounting the fact that there are sometimes really outstanding teachers, but the thing is, it's hard to objectively measure their performance since their teaching talent is not directly related to how well their students do. On the other hand, the "teachers" at universities are well respected since their talent is not only limited to how well they teach but the quality of their own research--the value is much easier to quantify.
This is true, for some odd reason, teaching in America is not socially respected institution as much as it is elsewhere.

Teaching in Canada is along the lines of nursing or something: it's professional, requires a degree of competence and certification, there is social value. It's not exactly 'doctor' but it's respected for what it is, as it is in most nations.

I think it's because people assume American teachers are not paid much, but the one's I know are paid reasonably.
Some of those charts do look concerning, and some of them are pretty clear, especially the delinquency rate on loans chart.

But are those three peaks all we have go off of? Does anyone know what it looked like prior to 1990 and if that era's delinquency rates too correlated with economic downturns?

3/3 is concerning, 10/10 is terrifying.

Yeah, because that's how physics is done. Bringing up how that approach fails when applied to other fields is a non sequitur.
> European Americans actually do better than Europeans - on average. + Asian Americans to better than Asians - on average. + Latino Americans do better than Central/South American Latinos + African Americans do better than Africans.

I've always heard this explained as a sort of "selection bias". Since immigration to the US (particularly for university education) is often seen as desirable, the people who manage to pull it off tend to be above the mean. Do you feel that explanation rings false?
You thrill me, sir! Sadly, my connections (such as they are) are far more banal. Even the mere thought of moving among such scintillating company sends me into gentle ecstasies!

No I need it like any other normal person who backs up their photos to their laptop. I don't lug around 5 lenses and I sure as hell don't want to lug around additional dongles that cost me $50 just to buy. Maybe USB-C becomes ubiquitous in 2-3 years time. Great, I'll consider my options then. Loss of MagSafe just to get this USB-C ubiquity is (again) not worth it for me.

Not really even sure why you're stating your opinion as some refutation of my opinion... My post was talking about why I won't be buying one. If you don't use an SD slot. Great, maybe this MacBook Pro is for you. If you want "the future in cabling and connection ports", this MacBook may be for you. If you want a "Touch Bar", this MacBook may be for you.

They're sitting in professional studios with million dollar hardware, and rendering their IMAX videos on external server clusters.

I am not sure what this has to do with me, a developer and photographer who is interested in upgrading his MacBook Pro and literally needs the exact opposite of this.

To grok self-esteem, one must grasp eudaemonia.

Self-esteem is reliance on your own power to think, judge, and act; regardless of what others may feel, say, or threaten. If some snowflakes cannot stand being judged by others, or cannot judge themselves, they do not have self-esteem.

As for post-modern "teachers" who believe that unfounded praise, unrelated to achievement, is the source of self-esteem -- they are nurturing lemmings, alienated from their true human potential.

https://www.washingtonpost.com/local/education/majority-of-u...

I'm no fan of the American education system, having suffered through it a full 12 years, but I have to believe it's not the primary cause here. Math is hard, and near impossible if you're stressed. I excelled at math, despite relatively boring math curricula. Why? Because I wasn't stressed as a kid, my family was stable and did not suffer from any serious physical and mental illness, and one parent always made enough money so that the other could stay at home throughout my entire childhood. I had an enormous advantage, and most all of the kids I knew through advanced math classes and math competitions had a similarly charmed existence.
I mainly agree but I believe the narcissism is in the parents more than the children. It is then passed on to the children.

No one wants to just admit their kid is pretty average or below average at certain things. They believe they have failed themselves and that there is no way that their offspring could just be a regular person.

Of course it has become harder to be a regular person and have a fine life in modern, Western society. We don't have the regular person jobs anymore that a regular person who is pretty average can take up like they could generations ago.

The stakes are high and a smaller and smaller group of high achievers, or what appear to be high achievers get all the spoils. A parent has an instinct to make every effort to guide their offspring to that to the point you get average kids who honestly believe they are well above average. It has been reenforced.
Oh come on, use your imagination. The feet evolve for carrying eggs. They re-develop live birth. The young learn to hang on from the first moment. They fly earlier. That's just the ideas from 20 seconds of thought.
