News on China's scientific and technological development.

Mathematical physics, Mathematics and Physics in Russian universities are completely drained. Very few top researchers produced after the fall of the USSR. Mathematical physics is again a weird field now a days . With string theory hitting roadblocks. Very few theories after 1970s have been verified. Its over to engineers and experimental physicists to prove those results.

Russia is clearly still capable of progressing in modern physics research, however diminished it has become.

Moreover, the latent talent is still there:
Russian students won five golds for physics in Tokyo—three golds and a silver in Zurich for chemistry.

There's hundreds of various chinese labs trying to replicate the room temperature superconductor results. Will have confirmation in 2-3 days

From what I read, it seems the superconducting result can be produced quite easily. So indeed, I expect researchers from all over China working overnight on replicating these results

Ironically enough, if the paper is indeed valid, China would benefit a lot more than the US lol

The problem is that the material only has like 300 mA critical current, so it can't actually carry all that much electricity.

All superconductors have critical currents. A current produces a magnetic field, and all superconductors have a critical magnetic field strength at which they are no longer superconductive. 300 mA superconductivity is tiny.

David P Goldman’s latest piece. He’s given up on the US beating China and is now trying to argue for a way for the US to stay in the tech race.

I'm been saying the same thing for a while now. If both countries can focus on investing in themselves, the resulting tech advances would be a boon for all of humanity. The type of zero-sum tactics employed by the US, however, is both ineffective and self-defeating.

Preventing catch up is just not a sound strategy because it's just so much easier to play catch up. Take EUV for example, a tech that ASML started to try to get out of the lab some 20 years ago. At the time it was not known if the commercialization was possible, AI was just the stuff of science fiction, and entire labs had less computing power than an iPhone. With enough money, will, and time, catch up using current day knowledge and tech is inevitable. The only hurdle is that reinventing the wheel by the upstarts will necessarily be more costly than capitalizing on sunk cost for the incumbents. Sanctions remove the ability for the incumbents to compete using their first mover advantage and thus remove this only hurdle.

Competitors. The cabbagization of medical imaging has begun.

Another big Chinese player in high end MRI machine manufacturing.

Back in 2022, Shenyang based Neusoft Medical officially announced the launch of the first high-end 1.5T self-developed magnetic resonance device in China. entirely design and produced by this company.



later that year, Neusoft Medical announced China's first 3.0T MRI high end Medical machine.



and we all know that, last week 'United imaging' successfully mass produced 5.0T high end MRI device.

Neusoft Medical and United Imaging are in forefront of China's high end medical machine.

Another Shenyang based Medical equipment maker 'CAMPO imaging' made serious breakthrough in high end CT scan medical machines.



High end medical devices are some one of the most technological advanced machines developed by Humans. i m not an engineer but my friend told me, MRI device is second only to lithography in technology and required ultra precision to manufacture.

GE , Philips , Siemens and Mitsubishi have had Monopoly for decades and earned Billions. its time to cut off some market share from them. Philips already starting to loose share in mainland.

China also did major breakthrough in other high end medical devices. will post some other time.. very interesting information.

It's also possible that the small critical current can be improved after making refinements to the materials and synthesis process. The initial research was done by 6 guys and it's not like they spend years tweaking and making improvements to the chemical synthesis process. Now thousands of million dollar labs are working on it, vast improvments could be made, just like with any other material in the history of material science.

Just by the result of the recently concluded high school Mathematics and Physics Olympiad in Japan and Chemical Olympiad in Swiss , future are looking bright for China. The gap is going to be larger in the future.

The entire background behind the research is quite the story. Though with all the details surrounding this paper I'm not quite sure what to make of it for now. Just have to wait and see, I suppose.

they need to know the mechanism first otherwise every tweak would just make it worse.
