Verifying the attraction of room temperature superconductivity is not only the result.

　　Original title: Verifying the attraction of room temperature superconductivity is not only the result.

　　Since the beginning of this year, topics related to "room temperature superconductivity" have frequently appeared in hot searches. In March, a team in the United States claimed that the superconductivity created could work at room temperature and relatively low pressure, but it was temporarily falsified because it could not be reproduced. At the end of July, a South Korean team described the copper-doped lead apatite material named "LK-99" in the paper, which can show superconductivity below 400K (about 127℃), and published relevant experimental data including molecular structure, which triggered a global replication experiment.

　　What is superconductivity? In a nutshell, the DC resistance of superconductors suddenly disappears under certain temperature and pressure conditions. Once discovered, superconductivity is expected to improve energy transmission facilities, and because of its diamagnetism, superconductivity can also provide support for thermonuclear fusion, magnetic levitation and other technologies. However, for a long time, the harsh conditions for realizing superconductivity have limited the application scope of this technology.

　　Can room temperature superconductivity, which has been heated up, really be realized at present? There is not enough evidence to prove or falsify this conclusion. Around August 1 ST, multinational laboratories spoke on topics related to room temperature superconductivity. After the team of Beihang University synthesized materials with highly consistent X-ray diffraction patterns, it failed to reproduce superconductivity at room temperature, while American researchers thought it was possible through theoretical calculation. The four materials in the live broadcast of Huazhong University of Science and Technology failed to show the "Messner effect" needed to prove superconductors. There is still a way to go before we can verify the existence of room temperature superconductivity.

　　Jumping out of the debate about the experimental results by netizens, this topic can generate such a strong "magnetic field" in the online community, which makes the relatively unpopular field of materials science hot, and it is also quite enlightening. At one time, scientific experiments and theoretical verification were too far away from the public, even though the results of papers were frequent, it was still a mystery to us. Not to mention that some reports are lagging behind or inaccurate, which deepens this gap.

　　The rapid popularity of the concept of room temperature superconductivity is inseparable from two videos. One is from the Korean team, and the other is uploaded to the domestic video platform by the members of Huake team through their personal accounts. The laboratory pictures in the latter video are accompanied by the explanations of the experimenters and the popular science in the comment area, so that ordinary netizens can also get a glimpse of the charm of scientific experiments, and the barrage of "witnessing history" and "believing in science" is crowded with screens. Video spread first with the help of network platform and knowledge community, which further boosted its attention. With the help of this trend, some people posted the application direction of popular science superconducting technology, some people carried research results at home and abroad, and practitioners in related fields shared their research experiences and exchanged ideas in real time.

　　Science is interesting rather than boring, and it is close to life rather than shelved. Undeniably, the network environment is complicated, and it is difficult to tell the truth from the truth. Only rigorous scientific experiments can tell the truth. The more the truth is debated, the more clear it is. I hope that after all kinds of guesses are mutually proved and refuted, the light of science can be lit in more people's hearts. (Moda)
