"Our experiment suggests at room temperature the Meissner effect is possibly present in this material." which is very likely related to superconductivity.

honestly, I fail to understand this paper. might vaguely grasp what it aims to do, but totally lost when it comes to the framework and the objectives of its experiments.

If there's an architecture that could be 10% better, I think it's highly unlikely that we would conduct ablation experiments, since it's too expensive, It's really a pity compared to CV.

Ever since Gemini's demonstration, I've assumed that all the promotional cases Google present are greatly exaggerated, especially since they don't offer trials.

In current theories, superconductivity is the only reasonable explanation for these strange characteristics.

Yes, especially since this paper was published following the Korean Validation Committee's statement on the 13th, which did not support LK-99. However, the Chinese team's experimental data is quite substantial, and the material th

Evidence of superconductivity in LK99 materials, presented by a Chinese team, is presumably the first experimental support for LK99-type superconductivity. The paper lacks evidence of zero resistance, attributed to the presence of only a sm

I often observe similar phenomenna in CNN related reserch. which indicate that the model indeed can learn from a single example, but sadly, this requires the dataset to be randomly distributed, In real-world applications, new data does not

The optimistic aspects are: 1. The diamagnetism of LK-99 is very strong; 2. In almost all experiments, LK-99 has only exhibited one-dimensional diamagnetism, which is hard to consider as fraudulent coincidence; 3. One-dimensional diamagn

However, we have never seen a material with such strong diamagnetism that is not a superconductor

Ignoring the differences between LK-99 and the levitating frog is foolish. 1. The diamagnetism of LK-99 is more than ten thousand times that of the frog; 2. LK-99 only exhibits one-dimensional diamagnetism, whereas the frog has three-dimens

The probability is quite low, because that guy conducted the experiment through live streaming, and failed once. Then, he conducted the second experiment after adopting some suggestions from netizens.

It depends on how pessimistic you are about human nature. If humans are doomed to perish because of their own stupidity, greed, and fragile flesh, then AI is the only hope for humans. What this means is: you can’t expect aliens or gods to c
