Facts. I work in a different field and it is a similar story. China has strong practical and incremental research but rarely makes the paradigm changing breakthroughs. Even in the most recent AI boom, neither LLMs nor diffusion models nor attention transformers were invented by Chinese, though Chinese researchers did make an important intermediate contribution in ResNet. The West is still the overwhelming source of the most ground breaking research.
Curious, bcoz i hav seen some articles in the past few years, that mainland China has been building new labs, and scientific facilities recently, like the underground atom research thing like "cern", also the one in inner mongolia, space station etc... maybe they lag in breakthroughs, bcoz they hav no facilities yet available b4?

a huge part is who gets to define breakthrough vs incremental.

first sample return from far side of the moon by Chinese? "incremental".

giving billions to old oligarch companies to do stock buybacks? "a revolutionary breakthrough in technology that will energize our manufacturing base.”

paying millions to confident sounding wht guys for fake medical research and still not fire them after being exposed as fake? "ensuring academic freedom for those with dissenting voices from the mainstream."

get it?

"Chinese scientists made a milestone achievement Sunday by using an independently developed resistive magnet to produce a steady magnetic field of 42.02 tesla, equivalent to over 800,000 times the Earth's magnetic field, breaking the world record set by the US in 2017."

Didn’t someone say recently that you need 20T to move seawater? If so this could be used for propulsion, right?

Chinese scientists from the Westlake University made debut of the lightest AR glasses in the world. The lenses are made from a single layer of SiC manufactured with domestic high end nano print technologies. Each lens weighs only 2.7 grams.

全彩AR眼镜目前重量还比较重,不便于佩戴,经西湖大学技术孵化,AR眼镜轻便化、多功能的“中国方案”成为现实。AR是Augmented Reality(增强现实)的简称,AR眼镜可以让佩戴者在现实世界的基础上叠加虚拟景象,并通过传感和计算实现虚实融合与虚实互动。

9月24日上午,西湖大学国强讲席教授、副校长以及慕德微纳(杭州)科技有限公司首席科学家仇旻在浙江省科协大楼的科学咖啡馆展示了一副超轻薄的碳化硅AR眼镜,实现了单片全彩显示、无彩虹纹、镜片极轻(2.7克)、极薄(0.55毫米),双目重量仅5.4克。

这不仅是该眼镜的首次亮相,更是“极致轻薄无彩虹纹碳化硅AR衍射光波导”这项科技成果的全球首发,其可以把光学影像“投射”在透明镜片上,在看到电子影像的同时,也不会屏蔽真实世界。

西湖大学仇旻教授团队多年来一直深耕于微纳光学领域,在微纳光子学理论、微纳加工与制造、仪器装备等科研方向硕果颇丰。依托多年的科研积累,也为了解决产业需求,仇旻教授团队的杜凯凯博士与团队中志同道合的同事们成立了慕德微纳(杭州)科技有限公司,专注于AR衍射光波导、衍射光学元件、超构光学器件等产品的研发。该公司自成立以来,在微纳工艺特别是光波导模板加工方面积累了大量工艺的能力,实现了国内高端纳米压印模板从零到一的技术突破,填补了国内AR产业链的空白。为了进一步改善AR衍射光波导的性能和佩戴体验,团队打破常规,将微纳光学技术实力与完美的材料性质相结合,把这款极致轻薄的碳化硅AR眼镜打造出来,并走出实验室,走向公众视野。
