Hah. In the USSR an average engineer earned less money than an average worker. I'm not joking. But STEM was seen as far more prestigious than manual labor. This was very much a cultural thing, pushed by the government (engineers are useful!). Another thing, there was a huge societal pressure to excel at school. It was common for parents to check their children's marks every day. There's a very famous picture about it…

It was done by individual schools, there were no hard-and-fast rules.

Straight "A" students did get some additional rewards, such as trips to summer camps in Crimea.

From the book being reviewed: > All joking aside, we fledgling mathematicians understood that the single most important thing was not raw intelligence or knowledge (Americans tend to lag behind in the latter compared to all international students). What mattered was passion. The way to become successful in mathematics, like almost every endeavor, is to care about it, to love it, to obsess over it. And in this, Easter…

> They had been trained, from an early age, to love mathematics more intensely. Nonsense, sounds like post-hoc rationalization. Maybe talk to some actual Slavic people. Sure the Russians had "math clubs" and "chess clubs" but it wasn't as if the US didn't have RadioShack and garage/ham culture. Talk to some of the older generations that still remember the Berlin Wall and you might also understand why so many women fr…

Universities in eastern bloc were really elite places. Only low single digits percent of people were able to enroll. Also majority of degrees were in STEM, education or medicine as they were deemed useful for the state. To get degree outside of STEM, political background of your family was checked and things like having family member (even say uncle) who emigrated outside of country or having grandparents who owned businesses or farm decades ago will get you discarded. So the smart kids usually have very limited path forward, so STEM it was (if you were lucky)

> Hah. In the USSR an average engineer earned less money than an average worker. But in the USSR, your ability to buy something was generally not limited by the amount of money you had. It was limited by whether you'd be allowed to buy the thing for other reasons. > But STEM was seen as far more prestigious than manual labor. Sounds like an engineer's money may have been worth much more than a laborer's?

> Sounds like an engineer's money may have been worth much more than a laborer's?

Not in general. It heavily depended on individual circumstances.

For example, machinists could earn a bit more money by using factory tools (lathes, drills, etc.) to make replacement parts for cars. And a lot of workers were stealing some of the product their factory was making. There was a common attitude of "everything around is common, so everything's around is mine".

On the other hand, engineers had more career perspectives. They were more likely to be promoted to managerial positions.

The article strongly implies this. > These days, the same scenes are dominated by Chinese and Indian kids. But China and India have large populations — the Russians were punching way about their weight, demographically speaking.

Also > Well, with the Soviets it all went in the opposite direction: they had a smaller population, a worse starting industrial base, a lower GDP, and a vastly less efficient economic system. How, then, did they maintain military and technological parity1 with the United States for so long?

The truth is, the Soviet bloc consistently made lower quality stuff or had much poorer training.

There's are a persistent set of myths that both the Soviets and the western arms manufacturers like to perpetuate.

The t-34 tank was the greatest tank ever (sometimes had 10:1 losses offset by 14:1 manufacturing)

The ak-47 is the best due to is reliability (poor tolerances made it both reliable and astoundingly inaccurate)

Soviet/russian tanks have not come out on top in any conflict for the past 50 years. On the battlefields of Ukraine, the t72 has been infamous for its design flaws wherein even mild penetration to the gun autoloader housed in the turret ring often leads to catastrophic explosions instantly killing all the crew inside.

In Israel's fights against Syria, syrian Soviet tanks had a critical design flaw wherein they were not able to shoot downward at an angle, effectively making them sitting ducks.

The last time Soviet jets had parity with the west was when both sides were copying the same German jet fighter designs appropriated from Focke-wulf at the end of world War 2.

Repeatedly in actual combat situations, the soviet equipment fares poorly... In Israel, Iraq, and Ukraine. Perhaps the only conflicts Soviet equipment has been used effectively is when Iraq deployed its mostly Soviet weapons against Irans mostly American weapons and even that's arguable considering the United States backed Saddam (and later obliterated his army with more modern western technology)

Thanks for the correction!

EDIT: wait a moment, now I'm confused: if her (Lena's?) marks weren't an issue for induction, why does it matter that her friend got jealous and ruined her test?

(or did I get this story right, but it wasn't necessarily a general all-Union thing, just that in this specific case a 2 would have been problematic for her troop/school/family?)

I think this must be a very stupid question, but I’ll ask it anyway. I always thought the Soviet Union was smaller than the US population wise, and really did punch above their weight. But Soviet Union census of 1970 lists 241,720,134 people, while the US census of 1970 lists 203,392,031 people. https://en.m.wikipedia.org/wiki/1970_Soviet_census https://en.m.wikipedia.org/wiki/1970_United_States_census Is this statis…

To be fair, the US and Western Europe were a somewhat combined bloc wrt. trade and being allies. So in that respect the combined USSRs population is smaller? But purely US v USSR, the latter has always had more people

The SU and Eastern Europe countries were also such a 'combined block' though (both for trade via COMECON and militarily via the TFCMA (aka 'Warsaw Pact'). Although AFAIK Western Europe had a much higher population than the Eastern European socialist countries.

But in general, the education and health care systems were usually the 'flag ships' with easy and free access for the 'working class' (which also means extreme discimination against anybody else though).

omg, 'midwit teacher deducts marks for failing to write answers in a designated format' this is exactly the math teacher my kids have. So frustrating.

In this country many teachers have been taught that it's important for kids to be able to use a range of approaches to solve a problem.

They then force them to use each of the prescribed set of methods even when they are totally inappropriate for the task. Any deviation from the method they are told to use for that question is wrong. No creation of your own adapted methods is acceptable.

In other words, the teachers were taught that kids should use different methods, but seemingly weren't taught why.

If Russians punch way above their weight demographically and are so good at math - how come then that the French have even more Fields medals per capita?

Maybe this article was written by a Russian troll farm, as it is essentially claiming Russian math supremacy.

This was a surprisingly interesting and well-written article. I hope people read it and not just the comments here :-)

I'm unsure if it implies that "lame school exercises" are unnecessary or just not sufficient (I've recently read articles about how teaching "insight" without exercises is detrimental, though perhaps doing problems implies getting that repetition-work).

Does anyone have good experiences with keeping kids math-interested as they get into their teens? My kid used to enjoy math in school, and love talking about math problems ("can you help me set up that triangle pyramid thing with the sums again"), but now is seemingly disillusioned and finds the school exercises boring. Combine that with, well, teen-age, and I fear it's going to be hard to get back the spark. Not that it has to come back, but I'd hate for the interest to turn into dislike due to lack of opportunities.
