如果係堅真係世界一大進步
係咪真係咁容易見證歷史
9up下4就全球同佢個partner買貴金屬嚟試 輕鬆財自 
paper既野吹大左又幾唔奇其實
academic publishing同real application不嬲係兩回事黎
同埋韓國佬個底不嬲都係花,造假三國之一,另外兩個係支同印

有時就算誤打誤撞先成功
希望能夠發展出有利做愛的東西 🙏🙏🙏
三星出手買起個技術未
LM
都係勿跟車太貼，睇完啾啾鞋講解，單係突破功率循環消耗呢點已經癲左，黎緊兩年內所有加密功具都會失效
如果係真基本上同核聚變同級，真係好想係真
內容係真就世界大變
一堆電子產品大升級先
一堆電子產品大升級先
真就正，見證新時代
同中國講專利？
係咪想傷害14億人民嘅感情？

A few days after the papers appeared on the arXiv – and mere hours after their sensational claims began circulating on social media, crashing Q-Centre’s website in the process – experts in the field urged caution. Richard Greene, a physicist at the University of Maryland, US who has worked on superconducting materials since the 1970s, observed that while the Meissner-effect video “looks impressive” at first glance, superconductivity is not the only phenomenon that can cause objects to levitate. “If you look carefully you see that sample 2 (which was levitated) has a large diamagnetic magnetization in the normal state,” he said. “So it could be levitated just because it’s a diamagnetic material.”
Another physicist, Douglas Natelson of Rice University, US, highlighted apparent inconsistencies in the two papers’ data on magnetic susceptibility, Χ. When Lee, Ji-Hoon Kim and colleagues placed their sample of LK-99 in a magnetic field, the six-authored paper states that the change in the material’s mass susceptibility (that is, Χ divided by density) amounted to 2.5 x 10-4 electromagnetic units per gram. “Assuming a density of about 7 grams per cubic centimetre, that gives Χ = –0.022, about 36 times that of graphite,” Natelson wrote in a Twitter/X thread dedicated to the findings. “That would be exciting, if it’s accurate.”
However, Natelson went on to note that “what appears to be the same data” also appears in Figure 4 of the three-authored paper, but with a completely different scale on the graph’s y-axis. This second set of numbers is, he said, “unphysical”, adding that the “pretty sloppy” discrepancy “does not encourage confidence in the results”.

佢公開晒嘅話我諗全世界都唔會講專利實在太有用
我諗全世界都唔會講專利實在太有用咁真係要多幾日其他人做成點先知
包裝個故事同將結果無限放大一直都係academic publishing既手段,外行人睇梗係勁,內行人好多時一睇就知
所以跟車唔好咁貼呀各位

如果係假嘢
咁淨係撚全世界幾日都算有良心
咁淨係撚全世界幾日都算有良心

都唔知你講乜撚野publishing手段 衣家講緊研究到常溫超導體 仲要係簡單到中學生都做到出黎
去唔到個製程
Tesla 超級電塔
本身都平野仲點炒
