Chinese-born maths genius leaves Harvard to help China become a powerhouse on subject

[S10]

So I count zero in that reply you supplied to my question of things a person in Brazil can hold in their hand and say thanks to China for.

Thank you for your reply. I knew you if you put your brain to good use you'd confirm my suspicions.



LOL! Ah so only the years when China passed the US in patents filed should be used as a baseline for eligibility of when say the average person in Brazil should be looking for some innovation from China that they can point to and say "Thank you China for this product" as years where China had lower patent filings than the US simply made them inherently junk patents and nothing should be expected of them.

Got it!

Anytime that Brazilian holds a 5G capable phone in his hand, he can thank China for a significant portion of those patents. He can also count the number of your brain cells with his hands.

You see, research and development is a function of economic progress. As China becomes richer, so does our technological achievement. We're already ahead in patents and research impact when we're just 80% of your nominal GDP. What will your excuse be in 10 years?

Again, pick up that maths text. You seriously need it. Why don't you ask these guys to give you some private lessons?

How is HSR some magic method measurement of success.

We have multiple companies that build jet airplanes that fly millions of people around the world. China has yet to have one successful plane.

Does that prove anything?

Infrastructure and manufacturing bring wealth.
The US's wealth WAS built on this by being one of the first countries that bring mass rail to connect the nation.

Planes are not as efficient.

Hold on, have you heard of Chinese Comac ARJ 21 and Comac C919 airliners ? And Comac C929 is coming, then we won't depend that much on Airbus and Boeing. By the way, Boeing airliners are close to junk these days, I don't know if the Chinese gov and companies are going to have big orders in the future.

I'm quite sure the Europeans managed to fully rail up their countries before the US did since they have less terrain to overcome.

I'm not sure I'm buying this logic of us being one of the first. We connected both our coasts together in 1869 while the steam locomotive engine was invented over 50 years before that. That's pretty slow.

Give US a break...You guys went dumpster diving in Boeing's trash to make those jets.

Britain was the first to start mass-rail, then the US, then Germany.
Germany was then bombed to oblivion and it's the reason why US remains supreme.

Then Japan was up, and kneecapped due to internal traitors, and now it's China and Asia time, but this time US can't bomb us to oblivion anymore.

It always comes down to rail (i.e. infrastructure) and manufacturing. You can't use planes in day to day life.

No, those Chinese airplanes were already well into production before the Boeing accidents happened and noticed.

Yeah let's see what wiki says about them:

Comac ARJ21 - Wikipedia

en.wikipedia.org

Resembling the McDonnell Douglas MD-80/MD-90 produced under licence in China. it features a 25° swept, supercritical wing designed by Antonov and twin rear-mounted General Electric CF34 engines.

Comac C919 - Wikipedia

en.wikipedia.org

First commercial deliveries of the aircraft are expected no earlier than 2022 or 2023, to China Eastern Airlines. The aircraft, primarily constructed with aluminium alloys, is to be powered by either CFM International LEAP or ACAE CJ-1000A turbofan engines

Comac C929 - Wikipedia

en.wikipedia.org

Construction of the first prototype began by September 2021.

---

You listed 3 planes where

The first is based on the MD80/90 but has new GE engines and a redesigned Russian wing

The second has no deliveries until this year. Not sure if has even passed certification yet by the Chinese Government.

The third is only a prototype.

Yeah, ,all you west, including wikipedia, like to claim credits on Chinese products and tech, it's a known fact.

"Different sources claim the ARJ21 closely resembles either the McDonnell Douglas MD-80 or the MD-90 which were produced under licence in China.[23][24] Comac states that the ARJ21 is a completely indigenous design."

"Some of China's supercomputers have been used to design parts for ARJ21."

C919 will be certified by Chinese gov this year. In the near future, the C919 engines will supplied by Chinese domestic ones.

Even Boeing airplanes are built with many foreign supplied parts.

Come on steam trains were common 100 years before WW2. That's irrelevant.

Is that why China is producing the most patents and quality researches in the world? Thanks for the compliment.

China has overtaken the US when it comes to the highest-impact research

1.67% of papers by Chinese researchers were among the top 1% of the most highly cited articles in 2019, versus 1.62% of those with US authors

China leads world in top scientific papers, new study finds

Study takes a fresh look at calculation of most-cited papers, finds Chinese researchers ahead in volume and quality.

Not everything is rainbows and sunshine though. We have some very strong competition from Team USA:

1.3 billion vs 84 Million and yet Germany is on same level

It's not about open society/democracy or anything like that. It's about the level of economic development. Super economic powers with high per capita income(not per capita GDP) have most breakthoughs in most basic fields. Because investment in basic science is costly and risky. Only rich countries can offer it. Middle economic powers with middle per capita income tend to have innovations in applied science. Applied science can make quick and decent money and is less risky. Low per capita income countries can only do copy work for quick money.

Before 2010, China was a low per capita income country. From 2011 to today, China is a middle per capita income country. Most China's innovations are in applied science. Very reasonable.

Wrong, progress can only exist in free society simply because you can question things.

Oh come on will you stop that. The MD80/M90 has a very very very distinctive look with the engines on the sides near the tail. I don't think anybody else has built a full sized commercial plane that way since the 1970's (other than maybe the Russians).

Old MD-80 with its distinctive pre-1980's style of having engines in the back near the "whale" tail which has long been ditched for engines under the wings.

ARJ21with its engines in the back like the MD80.

What does the new C919 do...why it puts the engines under the wings and drops the "whale" tail like modern aircraft from Boeing and Airbus.

Same level as what? GDP? Research published? Patents?

Wrong, progress can only exist in free society simply because you can question things.

Going by that logic, I guess Somalia must be the global innovation hub since there is no government to limit you. What a giant crock of shit.

Innovation is helped by a stable political environment, safe streets, economic prosperity, efficient infrastructure and an education system that produces steady stream of graduated suitable for the job market.

A similar tail of airplanes doesn't tell two have same or similar engines installed. I think the US do supply ARJ21 engines right now.

Laughable, you mean since Boeing and Airbus put the engines under the wings, then Chinese airplanes are not suppose to do that way ? You mean if someone has a design of a car with four wheels, then you are supposed to have your car design of 3 wheels or 5 wheels ? You are talking nonsense, a nut head.

Well somebody doesn't know the history of planes

They had put the engines in the back because most airports in the world back then made people walk onto the tarmac and use staircases to get onto planes. If you put engines under the wings you have to raise the plane further off the ground to prevent stuff from being sucked into the engines. Unfortunately that makes the staircases taller. To mitigate this they moved the engines up to the fuselage rear and lowered the plane so the staircase heights wouldn't be ridiculous. Remember you have kids and little old ladies that have to climb these things.

When countries around the world switched to passengers tunnels to the aircraft doors instead of staircases they were able to raise the plane heights and put the engines under the wings.

China built the ARJ21 in 2002 with a design used for tarmac staircases...something that went out of style long ago....like the 1980's.
