First video of LK-99 Full Levitation, aka flux-pinning This video was just posted to the Chinese video-sharing site BiliBili and claims to be a highly pure synthesized sample of LK-99. What is the physical phenomenon behind this and what does it mean? Levitation of superconducting materials is a phenomenon unique to what is called Type-II superconductors, and is an effect whereby magnetic field lines becomes 'trapped' as it passes through the material, providing the force needed to levitate. These are the popular images and videos of cryogenically-cooled discs floating above a magnet frequently seen online and in the pinned post on my profile. You can think of this like strands of hair being caught in gum - the gum is suspended in mid-air by adhering strongly to the hair as the hair passes through it. The hair in this case is magnetic field lines and the gum is the Type-II superconductor. Just like hair comes in individual strands, or in other words hair is 'quantized' or 'discrete', so is the flux trapped at the 'pinning centers' quantized in what are called 'magnetic vortices' - the quantization of pinned flux lines is a key property and distinguishing characteristic of Type-II superconductors (although technically can occur in Type-I superconductors if the material thickness is smaller than the London penetration depth, which is indeed very small - specifics for the physics nerds out there). Flux-pinning is entirely unique to superconductors and is also wholly distinct from the Meissner effect. It is not a property of diamagnets or diamagnetism. At @TRIUMFLab I contributed to flux-pinning studies in Niobium crystal superconducting radio-frequency cavities used for particle acceleration. In that application, trapped flux poses an issue by increasing the remnant surface resistivity of the cavity, which has the effect of decreasing its effective quality factor or Q-factor, which is a measurement of a resonators efficiency. SRF cavities typically have Q-factors of 10E10 and trapped flux at pinning centers reduces the maximum effective accelerating electric field used to drive charged particle bunches close to the speed of light. Flux pinning is thought to arise in some Type-II superconductors by small imperfections in the crystal, also called volume defects, that enable flux to penetrate the material. In SRF cavities an issue that arises is any magnetic field that is passing through the material, e.g. by the Earth's background field, can become pinned or trapped inside the cavity as it transitions into a superconducting state. See some attached plots in the comments from a study showing how the surface resistivity of SRF cavities increases the more there is a background field as the cavity transitions into superconducting state. This is the first video I am aware of that claims to show the flux-pinned levitation of a LK-99 sample. If this is in fact what is happening, then it is a very unique and promising finding of this new materials properties and potential for future study. If this is real then it is truly ground-breaking

Rep. Jason Crow Says Bio-Weapons Have Been Developed to Target People Based on DNA “There are now weapons under development, and developed, that are designed to target specific people…You can actually take someone’s DNA, take their medical profile, and you can target a biological weapon that will kill that person.”

Watching conservatives now blame the US Navy and US Coastguard for CONTINUING to search for missing people after hearing a sound near the Titanic that “COULD HAVE BEEN” the Titan imploding, completely baffles me. 1) The Navy specifically stated that they didn’t know if the sound they heard on Sunday was the Titan. They then continued to analyze the data. 2) Even if they knew it was the Titan, to call off the search and rescue would have been the most irresponsible thing they could have done. 3) To try and attack Biden over this just shows how partisan some people really are. There are things to blame Biden for or the Navy for or the Coastguard for. This is certainly not it.

What’s with all this degenerate mind rot on Twitter lately? I don’t want to watch people being split in half by busses and shot in check cashing places when I’m winding down on my couch at night. This content started spamming everyone’s feeds over the last 6 months and it shows.
