tldr:
The samples people are making behave in very strange ways that can only be explained by superconductivity. Though, a novel form of Koreamagnetism is possible, since it hasn't been proven the grains of LK-99 sand are actually superconductive.

This brings the question, when humanity finally moves to other planets to colonize, what happens to Earth? Does the UN take over as a neutral zone?

>It's the weekend! They're closed!

I'm a big believer in time off and weekends, but I figure the one time labs would do overtime and stay open over the weekend would be in the case of confirming potentially world/life/economic changing technological advancement. Especially when the process is straight forward and simple enough.

>>15640298
Why would they rush?

>>15640277
I dont need arguments and evidence, the mere fabric of reality adjusts to my whims. this shit is fake and gay and in time i'll be proven right.

>>15640298
why would anybody stay late for something the overwhelming majority of people who have access to quality labs think is a BS/very unlikely to be reproduced?

>>15640243

This. If you were a researcher that really thought the initial result was real, you'd want to be in the lab just out your own intellectual curiosity

Argumentum ad populum

>>15640304
Experience, for start (not that guy)

>>15640304

It's not about rushing. It's just working to confirm that either the next milestone in human technological advancement is real or not.

>>15640306

There's literally still nothing but speculation by retard hobbyists and wanna-be eggheads on both sides of the issue.

If it took one OT weekend, just one, to blow everyone the fuck out and put the issue to rest for good that this is real or not, then why not do it? Again, especially since the process is so straightforward.

What is the standard for replication? What criteria must be met?

there's a lot of people DIY-ing it. some student posted the last video with the SC hanging from a magnet. there surely are a lot of people/entities that have good results and are not spamming twitter with it

Ok, one of the biggest misconceptions I’m seeing is that most normies seems to think that simply showing a photo of “magnetic levitation” is proof of the Meissner effect and therefore superconductivity. It’s not. To help non-professionals better understand, here are at least five things that must be shown to prove superconductivity, off the top of my head:
1. Resistive transition to an R = 0 state below Tc. It needs to be actually R = 0, not R = 10-5 or some other “low” value. Also, the width of the transition cannot be extremely narrow. For fundamental reasons, the width of the transition is proportional to Tc, so for a room temperature superconductor we would expect a very wide, gradual transition in R(T). This is doubly true for a material that depends on dopants (disorder) to generate superconductivity.
2. Magnetic field expulsion, ie the Meissner effect. This needs to be shown in both zero-field cooled and field cooled data. If it’s only shown in zero-field cooled measurements then that could indicate a “perfect metal” state or a magnetic state, but not superconductivity. Also, the Tc needs to agree with the Tc from resistivity measurements.This sounds silly to say but there have been claims of room temperature superconductivity where the values of Tc are contradictory!
3. A jump in the heat capacity at Tc, which is connected to the condensation energy (or energy saved) by the electrons when they form Copper pairs.
4. Quantum measurements. Superconductivity is a fundamentally quantum effect. This means you need to show quantum measurements of the superconducting gap opening at Tc, quantized charge number 2e, and preferably also the phase coherence and symmetry of the wavefunction. This can be done with tunneling experiments and optical absorption or spectroscopy.
5. Persistent current. If there is truly a superconducting state, then current will flow forever. If there’s any decay at all, even if it takes days or weeks, you don’t have a SC.

Overcel’s Wager -

There is actually no justifying being a backsissy other than lack of intelligence or more likely mental illness.
Even if we were back (we are demonstrably not), at some point it would be the final time we were back. At that point it’s necessarily over.

It will always be over, there’s no other logical choice. No reason for you all to gamble with how dumb you look in the archives later. It’s iron shavings in the samples anyways.

>Again, especially since the process is so straightforward.
It takes 72 hours of cooking and you can ruin the sample by farting too loud.
We're still solidly in the "we're not entirely sure the exact process to reliably make this substance >50% of the of the time".

>>15640330

Oh, and i'm trans btw. Dont know if that matters.

>>15640331
it's over means it didn't pan out. you're conflating it with the over from "we've done it bois, it works, it's over" which has a completely different meaning

>>15640193

this is one of those grey situations. on the one hand yeah, kinda sux to have your work leaked by some retarded colleague.
on the other hand, we might have never seen this material if he didn't spill the beans. or maybe we would have gotten it way later. so in a sense he could very well be a fucking hero. imagine the extra people that will live instead of die just because the tech came that many days/weeks/months/years earlier than it would if he didn't say anything.

>For reference, the recipe necessary for synthesis was leaked, but the know-how of copper thin film thermal deposition (coating) technology, which is the most important for LK99, was not leaked.

>>15640533
if we would have never seen this material then it means after more research it was determined not to be RTAPS in which case who cares if it wasnt released? if its real they would have released it in due time and it would actually have proper data and probably a better synthesis recipe that isnt wasting everybodys fucking time like now

>>15640340
This leddit post is dogshit anyway. The author completely ignores the theory and makes up some wordcel shit about the temperature band being as wide as Tc.

Trumpets are sensitive to air pressure, but that doesn't mean they only work below a certain temperature. It means they work in a range of pressures around ambient, and different things fail if you go above or below.

Until we know the actual mechanism behind this (and we barely pretend to know the mechanism behind superconductivity in general) we can't be making arbitrary declarations that all rules need to be followed.

In other words redditor be silent

I wouldn't worry about it.

WW3 will start with energy weapons.

>>15640514
Kwon is a traitor to America (yes, SK is part of our empire). LK-99 should have been transferred to Lockheed to bolster American national security. Now China and Russia will be able to build powerful new weapons and advanced radar that can detect our stealth drones. Kwon should be extradited along with that other traitor Assange.

>>15640686
>this is definitely not a superconductor. i wouldn't worry about it. nothing is real please stop pointing that gun at me
so this is how ww3 starts
spies are having a lot of fun right now

So now that part of the LK-99 recipe is leaked, can they still patent it? Suppose a commercial start-up group that uses LK-99 is created, are they liable to be sued?

But what if it fully levitates over a single circular or square magnet, i.e. one that doesn't have a dimple in the field? What if it levitates UNDER a magnet? I can't think of any ways to explain these without superconductivity or hoaxing.
You don't have to have a SQUID, a super sensitive ohm meter, etc.
Just show that it levitates in the right way.
Anons can do this. Anons WILL do this.

>>15641259

He is a pseud, guy didn't know shit about condensed matter chemistry: do you know how many things you can bake that can produce diamagnetic crystals of that size? I'm not an expert in enantioselective synthesis but I can tell you that he, and anyone who believes this is a RTS, is jumping into very wild conclusions from something that is in fact quite common. This is why science should only be done by people with proper credentials, and preliminary results should never be shown to the general public because most people don't understand the scientific method at all.

>>15641346
>something that is in fact quite common
Is that so
>do you know how many things you can bake that can produce diamagnetic crystals of that size
Not at all. Do you? Why don't you bake us some. I haven't heard of powerful diamagnetic crystals being so easy to create.

Russia and China constantly lie about their military capabilities as a result of their fucked up internal politics and breathtaking levels of corruption. They can't even match 90s western capabilities at scale, let alone future ones. Especially if the material requires as much precision manufacturing as it appears. Its a long step from a couple grains to kilometers of cables and viable lithography deposition.
Quit your hyperventilating, in other words.

I don't see anything in his video that would indicate a strong diamagnetic material, remember this is a very tiny object, half millimeter long at most. You can smash a pencil in your desk and the lead will exhibit the same behaviour even exposed to a magnetic field.

>>15641455
Sorry I meant "when exposed" not "even exposed".

Here is a video, although it's not exactly the same because this is probably pyrolytic graphite (the ones used in retractable pencils) so the effect is stronger and you can actually fully levitate the entire lead:

>>15641477
Recently room temperature superconductor was claimed in Pb10−xCux(PO4)6O (also known as LK-99) with x ∈ (0.9,1.1). Density functional theory (DFT) calculations suggest that the conduction electrons are from the doped Cu atoms with valence close to d9. Motivated by this picture, we build a two-orbital Hubbard model on triangular lattice formed by the dxz and dyz orbitals with total hole density (summed over spin and orbital) n = 1 − p. When p = 0, the system is in a Mott insulator within this model. When p > 0, we derive a t−J model and perform a self-consistent slave boson mean field calculation. Interestingly we find a s wave pairing in contrast to one-orbital t-J model which favors d + id pairing. S wave pairing should be more robust to disorder and may lead to high Tc superconductor with sufficiently large value of t and J. However, the DFT calculations predict a very small value of t and then the Tc is expected to be small. If LK99 is really a high Tc superconductor, ingredients beyond the current model is needed. We conjecture that the doped Cu atoms may distort the original lattice and form local clusters with smaller Cu-Cu distance and thus larger value of t and J. Within these clusters we may locally apply our t-J model calculation and expect high Tc s-wave superconductor. Then the superconducting islands couple together, which may eventually become a global superconductor, an insulator or even an anomalous metal depending on sample details.

Prototype with a couple examples on a single frigate. Publicly released "test footage" was instead a P-800 missile. As far as anyone can tell, it isn't a functional weapons system. This may change in the future. Even the Russian admiralty admits it has "teething issues", which is a rare god damn statement for the Russians to make.
Every magic Russian wunderwaffe is like this. From the tsunami nuke, Kinzhal, supercavitating torpedo, nuclear powered cruise missile, to even manned vehicles like the Su-57, Su-75, and T-14. Russia hides the massive gaping flaws and never fixes them. Retards don't understand when it comes to the military, no news is bad fuckin news. Product problems are a universal thing in any industry. Public acknowledgement means they're being fixed. Sweeping it under the rug means they aren't.
Just remember, the USSR knew about the AZ-5, Xenon hole, and positive void coefficient issues with the RBMK. They knew it over six years prior to Chernobyl. It was chosen to hide the problem and not fix it, instead of doing the right thing. That is how Russia operates in all fields.

Did not see this happening, but everything else happens also with graphite.

Note though that pencil lead is not pure, so you will observe some ferromagnetic behaviour as well.

The video just demonstrates diamagnetism, if you want to try to replicate the partial levitation you saw in the supposed LK99 specimen then just smash a pencil on a paper and put a magnet below and perpendicular to the paper.

You may need a magnifier if your eyes are shit, but seriously, you can't ask for an easier experiment for fuck sakes.

>>15641529
You can see it from the original Korean video, and Andrew claims that's what his sample did.
If the graphite is repelled upwards by a magnetic field beneath it, I don't think it's possible to make it stay in place as the whole thing is turned upside down.

>This problem was resolved when it was demonstrated that the analogy between tsunami waves and EGWW does not hold: EGWW dissipate most of the energy on the continental shelf, first by wave-seafloor interactions, second in a nonsaturated breaker as previously explained (Le Mehaute, 1963). Therefore, the damages would be limited to coastal installations much the same as would result from large storm waves. For example, on the East Coast, the sand dunes may be overtopped.
>In this operation, however, it is realized that the amplitude of EGWW is depth controlled, and that it is not possible to generate a large EGWW in shallow water, regardless of yield.
>Typically, at most only 4% of the explosion energy is transmitted in the form of water waves.
>Underwater explosions are poor wave generators.
Overtop the sand dunes means about a 5m wave from a 50mt warhead, and it doesn't scale linearly with yield.
In summary its shit and retards lap it up.

the fact that resistance is measurable at all (all the figures were greater than copper LOL) Means it's not super conducting, it's more insulating than regular copper (also noise floor and extremely inconsistent measurements of something more insulating than copper means their rig is either dogshit, or the material is so low quality the probes can't measure it)
