News on China's scientific and technological development.

Are you sure there are 2?? I'd think that one was the latter upgraded one of other; how could they have 2 independent systems both named Tianhe-1A? ...

Thanks. Interestingly, wiki only acknowledges the 2.57-4.7pf system as Tianhe-1A and successor of Tianhe-1 (

). The 0.77-1.34pf system is not mentioned. If all 3 are existing Tianhe-1 derivatives, they need to rename the faster one Tianhe-IB.

Tienhe-1A is probably the type name. They are in 2 different location with the faster one in

I go to bed now LOL
 
What I meant was they have the same architecture although the number of cores and size of memory may be different.
LOL what I meant was
#1/#2
is186368/53248 = 3.5000 (cores), and 4701/1342.75 = 3.5010 (Rmax);
#1 and #2 of course from:

Prototype dish for SKA super telescope assembled in China
Xinhua| 2018-02-06 22:22:45
Please, Log in or Register to view URLs content!

he first fully assembled dish for the Square Kilometer Array (SKA) radio telescope was unveiled Tuesday in Shijiazhuang, capital of north China's Hebei Province.

The SKA, an international effort to build the world's largest radio telescope using arrays in Australia and South Africa, is not a single telescope, but a collection of telescopes or instruments, called an array, to be spread over long distances.

After completion, the SKA will detect faint radio waves from deep space with a sensitivity about 50 times greater than that of the Hubble telescope. Individual radio telescopes will be linked to create a total collecting area of about 1 million square meters.

The state-of-the-art 15-meter diameter dish unveiled Tuesday is one of two final prototypes that will be tested ahead of production of an early array.

It is the first time China has played a leading role in the development of the SKA dish, showing that the country has made technological breakthroughs in radio telescopes, said Hao Jinxin, deputy head of the National Astronomical Observatories under the Chinese Academy of Sciences.

"This is a major achievement by all the partners involved," said Philip Diamond, director-general of the SKA Organization, which is overseeing the project.

"Our Chinese partners are extremely well resourced. They have demonstrated that they have the technology and capability to construct a telescope with the specifications that the SKA requires," added Mark Harman, SKA Organization project manager for the dish consortium.

A second dish will be shipped to South Africa and assembled there to conduct real observations for the first time in the next few months, the SKA Organization said on its website.

Supported by 10 member countries including China, Australia, Canada, South Africa and Britain, the SKA has attracted scientists and engineers from about 20 countries.

When my father first came to the US in 1989 as a poctdoc, he thought it would be impossible to see this in his lifetime. It's a good start, but there's still a lot more to do and a lot more improvements needed before China becomes the undisputed global leader in science and technology.

China Just Overtook The US in Scientific Output For The First Time
We just passed the tipping point.

PETER DOCKRILL
23 JAN 2018
A national report on the state of US science has concluded the United States is still the world leader in science and technology – except by one vital, historic measure.

For the first time, China has overtaken the US in terms of the volume of total scientific papers published – a telling statistic that underscores the rapid strides in scientific achievement China has made on the world stage in recent decades.

"This year's report shows a trend that the US still leads by many S&T [science and technology] measures, but that our lead is decreasing in certain areas that are important to our country,"

chair of the National Science Board, Maria Zuber.

"It's critical that we stay at the forefront of science to mitigate those risks."

is published by the US National Science Foundation (NSF), tracking innumerable markers of scientific achievement and scale across countries (the 2018 online report clocks in at over 1,000 pages).

Among the many statistics reported, China's eclipse of US research output may be of the most concern to those in the American scientific community.

In 2016, China published over 426,000 scientific studies indexed by Elsevier's Scopus database – accounting for about 18.6 percent of the international total. For the first time, the US came in second, notching up 409,000 published papers.

It's not a huge lead, perhaps, and the US output still outranks China when it comes to scoring citations from scientific papers – although neither nation is a global leader on that front.

Sweden and Switzerland produce the most highly cited publications, followed by the US, the EU, and then China.

China's lead over the US in terms of research output isn't across all fields, with different nations offering different strengths.

For example, researchers in the US and the EU produce more papers (and patents) on biomedical science, while China demonstrates a lead in engineering research – as does South Korea.

By financial measures, the US still demonstrates impressive leadership, spending the most on research and development (R&D) - US$496 billion, 26 percent share of the global total - and bringing in the most investment to the tune of almost $70 billion.

But China's not far behind, with its R&D expenditure rapidly swelling by an average of 18 percent annually since 2000 (US was only 4 percent), to where it now commits $408 billion (21 percent of the global total), and scored $34 billion in 2016 in venture capital.

"The actual numbers are breathtaking for the speed with which they've occurred," writes economist Robert J. Samuelson in an opinion piece for

"China has become – or is on the verge of becoming – a scientific and technical superpower. We should have expected nothing less."

China Has Mixed Feelings About Elon Musk’s Falcon Heavy Success
While many Chinese netizens applaud Musk’s victory, nationalism pulls in another direction.

By Charlotte Gao
February 08, 2018

On Tuesday, in its first test flight, Elon Musk’s SpaceX successfully launched Falcon Heavy — one of the world’s most powerful rockets — from the Kennedy Space Center at Cape Canaveral in Florida.

Along with millions around the world, Chinese people were deeply impressed by SpaceX’s victorious launch, particularly the company’s breathtaking reusable launch system.

Soon after two of Falcon Heavy’s booster rockets landed safely on the launch pad, news reports with photos and video footage swept Tencent Wechat and Sina Weibo — two of China’s most important social media platforms. Thousands of Chinese netizens reposted the information on their own social media accounts and applauded Musk’s great achievement.

However, China’s national media expressed mixed feelings about Musk’s Falcon Heavy rocket.

For example, Global Times, one of China’s most nationalistic state-run newspapers, issued a series of articles on both its website and its social media account, introducing the launch in detail.

On the one hand, Global Times highly complimented SpaceX’s advanced technology, used in the latest launch, saying that the Falcon Heavy rocket has “totally crushed all other current rockets in the world.”

On the other hand, Global Times couldn’t help but attribute Musk’s feat to the United States as a whole and compare China’s space technology with that of the United States.

One of many Global Times’ articles on SpaceX wrote emotionally:

What really shocks us Chinese is not only that our country currently doesn’t have rockets of such magnitude, but the fact that we are almost 10 years behind; more importantly, what our country has to desperately catch up with is actually a private U.S. enterprise…

To put it more bluntly, this time the Americans showed us Chinese with pure power that why they are still the strongest country in the world and how wide the gap really is between us and them …

On February 7, Global Times even published an editorial in Chinese under the title of “The road for China to catch up with the United States on science and technology is still very very long.” Taking a rare tone, the editorial admitted China’s backwardness on technology and, at the same time, directly criticized some rising perceptions that “China has generally surpassed the United States as a whole.” However, the editorial didn’t forget to vow that China will take steps to improve its space technology.

Interestingly, the newspaper hasn’t translated this fairly balanced editorial (compared to its many other strongly worded editorials) into English so far.

China’s national TV station, CCTV, showed another interesting tendency in reporting the launch. CCTV focused most of its attention on the fact that the third booster of Falcon Heavy rocket failed to land on its launching pad on the sea, not the overall success of the launch.

While nationalism is deeply embedded in China’s national media reports, many Chinese citizens, impressed by Musk’s feat, reflected upon China’s problems from a totally different angle.

For example, one comment by an unknown Chinese netizen has been widely reposted. It reads:

The real difference [between China and the United States] is that Americans put this line “Made on Earth by humans” on Tesla’s engine … rather than “made in America.” The Tesla plays on loop “Space Oddity,” created by great British artist David Bowie in the 1970s, rather than the American national anthem. Inside the car lay a copy of The Hitchhiker’s Guide to the Galaxy, known as the science fiction bible written by British writer Douglas Adams… What truly makes miracles come true is mankind’s spirit of exploration and adventure… rather than so-called national pride.
