Read the graph, there is a sharp drop in resistance from 220K-250K. Its still not superconducting but it could be hinting something?
That’s what I was thinking. In the video he brushes it off as a potential equipment malfunction, but perhaps it’s the effect everyone is looking for.
credibility of LK99 claims is very very high. What are the medium term practical implications for all these potential applications?
Start shorting power companies.
Ok not sure how to phrase this: Could there be small pieces of RTSC inside the sample (causing the floating) But then enough impurities to not be able to complete a circuit through the sample? And cooling makes other parts of the sample super conducting?
Could be insulated RTP superconducting crystals, grains, islands with the bulk being a high temperature superconductor?
Certainly no expert here but if you take the original video and replications at face value it does exhibit strong diamagnetism at room temperature. Superconductors are diamagnetic due to the Meissner effect at their superconducting temperature. This would mean LK99 is a superconductor at low temperature and separately be strongly diamagnetic at room temperature (no Meissner effect if it's not super conducting). Would…
The few videos of lk99 show it reacting to a singular magnet. A property of superconductors that apparently diamagnetic materials don't have.
(edit) Also is it resistance (aka if I remember my EE degree correctly), DC only or also impedance where frequency also matters?

A sudden discontinuity like that but continuing the same curve and jumping back... that's equipment malfunction 99% of the time.

increased geopolitical tension
That is an interesting observation and puts words to some thoughts that I've had: if it turns out that this is 'the real thing' and the patent holds up South Korea is suddenly a superpower.
Frankly there is also zero chance that the patents are respected by all parties (i.e. China), regardless.

That doesn't follow at all. Lead and copper aren't exclusive to South Korea. The authors get prestige and the owners of whatever patents are granted get some money.
Novice question - does a material behaving as a superconductor occur all the sudden like a step function if resistance is plotted against temp and pressure - or does it ease into super conductor behavior?

Depends. This feels a bit like the Wright Brothers patenting wing warping. It's possible that innovation will happen so quickly that the original patents become worthless. Frankly there is also zero chance that the patents are respected by all parties (i.e. China), regardless.
