Calling it "LK-99" seems to have been a mistake. It gives the impression that the term refers to a well-defined material, perhaps even a mass-produced product like "iPhone 14" or "RTX 4080". This explains all t

What do you think is easier, making a possible superconductor, or popping it on top of a magnet and seeing if it floats? The latter is an "experiment" only in the sense of an elementary school science class. Why are we so obsessed

According to the screenshot attached to the tweet, it seems that the material needs to have oxygen atoms in exactly the right locations, too, not just copper. Annealing in an oxygen-deprived environment might not be conducive to that. The o

Well, in the case of LK-99 the production method itself seems to be part of the puzzle, and the original authors aren't noticeably better at it than anyone else. Even their best sample doesn't fully levitate. We need higher qualit

I live in a country where train stations are often surrounded by high-density developments. What most tourists don't notice is that there are massive multi-level parking lots underneath all that housing and office buildings, not to men

I wonder how much overlap there is between a) people who assign fault to bears, and b) people who actually, seriously believe that animals have rights and responsibilities like we do. If there isn't much of an overlap, we'd have f

For many businesses, there's a simple incentive that should make them care: SEO. Although Google and other search engines have said for more than a decade that their bots can execute javascript and navigate SPAs, the truth is that they

It's called grizzly country for a reason. Anyone who lives or visits there should be aware of the risks and prepare accordingly. There are plenty of warnings all over the place. If grizzlies were roaming freely in the town square, near

Does it matter? Even "rigorous" research depends on luck in many cases, because there are so many unknowns. Theory helps reduce the search space, but there are situations when a brute-force attack is the most efficient way to answ

Yeah, Stream is okay if you don't require bug-for-bug compatibility with RHEL and just want a familiar, relatively stable, rpm-based distro. I would say its role corresponds loosely to Debian testing, whereas Fedora is more like sid. I

Red Hat used to be a lot more lenient with the clones, just like Microsoft didn't care whether you used a genuine copy of Windows/Office or not. They probably assumed that once you became accustomed to CentOS, you would naturally

Judging from the Korean-language interviews making the rounds today, there seems to be some sort of political tension between the researchers and the so-called verification committee. There's disagreement about whether anyone actually

One would think so, if the rest of the world weren't already cooking up similarly half-levitating samples in their kitchens and garages.

It's the same in Korea where the research originated. A bunch of professors belonging to a hastily formed academic committee are trying to monopolize the public debate, quibbling about errors in the arxiv paper and demanding that Lee &

The problem is that no one has a pure sample of LK-99, only chunks of rock containing small areas of LK-99. So even if LK-99 is a true RT superconductor, we're only going to see levitation on the side of the chunk that has a high enoug

I would actually welcome scooters that only work on specialized tracks. Walking safely on the sidewalk will become as easy as staying away from those tracks.

I wonder how many of the 1.3T daily requests are made by misconfigured cloud servers with no local DNS cache, hitting popular endpoints like <service>.<region>.amazonaws.com or fcm.googleapis.com over and over again. Consume

It certainly doesn't hurt that this thing levitates . No need to squint into a microscope, parse a screen full of numbers, or try to make sense of false-color renderings. Either you have video proof of a levitating object, or you don&

So, higher concurrency in exchange for a higher chance of COMMIT failing. Not a big problem IMO if you handle failures properly (either abort or retry as needed), which you should if you're deliberately using this feature. In fact, one

You are limited by how much liquid your digestive system can absorb in any given hour. I've heard that it's somewhere around 1 liter per hour. Any excess liquid is going to slosh around in your intestines instead of entering your

It's the percentage of alcohol in your system (Blood Alcohol Content) that makes you drunk, not the raw amount. If you're drinking 30-50 units of water for every unit of alcohol, all that alcohol is going to be very diluted and ha

The framing would work just as well if we substituted for Google a certain not-exactly-friendly-with-the-U.S. regime that also happens to produce a shitload of smartphones. Whatever we don't want them to be able to do to our smartphone

Can we tell whether the mammal was actually trying to take down a dinosaur, or it was merely scavenging on a (nearly) dead dinosaur? Signs of resistance on either of them?

We've been enforcing this rule for long enough that most animals avoid attacking humans even if they could easily kill us. The rule has been written into their genes through sheer evolutionary pressure. Except house cats, of course. So
