paper recycling is profitable without any subsidies at all, and people do sometimes steal paper to recycle it

here in argentina there are tens of thousands of people who make a living by recycling, sorting through whatever trash they can get access to in order to find materials with enough resale value to scrape by. they haul plastic sacks or two-wheeled carts all over the metropolitan area, stacking them high with recyclables: aluminum, copper, car batteries, brass, whatever they can find. a crt tv left out on the curb will have its yoke broken off within an hour or three in order to harvest the copper. neighborhoods sometimes lose phone and internet service for months at a time because someone has recycled the cables. commemorative bronze plaques go missing from cemeteries

but the recyclers are not called aluminieros or bronceros or cobreros, taking the name of their profession from aluminum, brass, or copper; they are instead referred to by the most abundant material they recycle

they are the cartoneros, because what their carts are usually piled high with is cardboard, cartón

(needless to say this activity is not subsidized)
Speaks to a supreme confidence in the theory, surely? I'm a layman but imagine everyone is going to want to hear every wild idea these guys could think up if this works out. They might have been sitting on this for 20 years? Probably why I'm not, but If I were any vc person I'd be busting down their door trying to give them all my money
If you run a bunch of simulations to brute-force-find what you're looking for, you run into a problem of infinitely many things to simulate. It is better to use domain knowledge to eliminate things that don't work and narrow down things that would have high chance of working in theory to give some sort of directional guidance for your research.
Apart from levitation and resistance, free conductivity, what are superconductors really good for? Like how could an iPhone become better with super conductive room temperature materials?

> The neoliberal view is that you can prove your point by forming subcultures that do better than the surrounding culture.

Can you clarify who you actually mean here by neoliberalism? It seems a very loosely defined ideology. Do you just mean ‘the mainstream West’, or something more specific? It’s a strange -ism. It’s very vague in definition, and no one ever professes to be a member of it, yet it is ostensibly an ideology. And I only ever hear it used with a pejorative subtext, which is interesting.
Personally, I value determining the dark energy equation of state to be more valuable than discovering room temperature superconductors. My wife's view is the opposite. Which of us right, and why?

I was born and raised in Germany and I give a f*ck what other people think (I care ZERO percent). But to be honest I also left Germany (because I'm fortunate enough to do that) because society is blind in sense of taxes, social insurance etc especially if you are an entrepreneur. Rich or wealthy people in Germany are considered to be thieves or inherits of something/somebody. Believe it or not but many Germans feel ashamed when being wealthy (or they do not speak about their wealth ever, keep it a secret).

My thinking is that shame is a very broad term and there are many societies on Earth which are more shameless than USA with relaxed drug laws and DO NOT HAVE that drug problem.

There are high throughput DFT projects (e.g., the materials project) but (1) the calculations are very computationally expensive and (2) the search space is really large. People are doing cool stuff with ML and generative models, but it’s a pretty open research area still

Also, at the end of the day, DFT is still an imperfect approximate model. Relative trends are generally more reliable than exact correspondence with experiment, and it can have system-specific systematic errors that are hard to account for in a high throughput setting
My observation (ChatGPT and not the API models):

For code, 3.5 is superior. 3.5 allows for about 21k tokens of input, while ChatGPT 4 allows for around 10k. This also makes it a lot better for boilerplate work as at it can take a lot more input, and handles long conversations and iterations better.

Brainstorming, 4 is better. It's capable of some top tier brainstorming and it argues back quite frequently.

Unguided creative writing (describe a potato), they're roughly equal.

Guided creative writing (i.e. write a story around (400 words of requirements)), 4 is much better.

Poems and wordplay, 4 absolutely floors 3.5. Wider vocabulary and it's able to do rhymes and alliterations better, which humans are usually bad at.

For reasoning and riddles, 4 is still benchmark among the LLMs.

I really dislike that they named it GPT-3.5 instead of something like "Glide". It implies that it's inferior to 4, when they're just suited for different things.

As someone who is versed in semiconductor band structures but not superconductor band structures: What is it about Cu d-d interactions that causes the superconductivity?

Degenerate energies in semiconductors don't give rise to electron pairing, so I'm a bit out to sea with the proposed mechanism here.

So I absolutely agree with this. And yet this meme persists. I wonder what's creating the feeling that it's "dumber" in so many? Perhaps they're just noticing the limits that always existed previously? I'm not sure, and am interested in others thoughts on it.
Let me keep being pedantic and notice that a typical phone capacity of 10000 Joules divided by 2 seconds is still 5 kW of power, so not a trivial amount. I'd think 30 seconds (333 Watts) is more realistic.
That right belongs to the people, not the states. Which in slave states included the slaves. In two Confederate states, slaves were an outright majority, and in most of the rest, they were a large plurality. Do you seriously believe that Confederate politicians could be meaningfully described as representing "the people" dissolving political bonds, given that those politicians did not in any way represent all the slaves by design? It's about as meaningful as claiming that Spartan aristocracy represented helots or Messenians.

Not that it matters much. Even if it is democratic, there's no moral right to self-determination if that self-determination is explicitly for the purposes of brutal oppression of some minority.

Instead, you need to independently provide your numbers and hope they match. Or you can hire one of their "partners" who will help you file your fish taxes correctly, for a fee...
That domain knowledge wouldn't have suggested exploring this space for superconductivity.

Turn the material science problem around: instead of looking for a substance that has a specific property, look at many substances until small amounts of any interesting property (young's modulus, etc) show up. By looking for "anything interesting" you are more likely to find something of interesting (ideally, several somethings). And then you also know a starting place to begin optimiziation.

(I'm not saying these things out of ignorance; this technique has worked well for me at times when I had exceptionally large amounts of CPU available to me, and it's also worked well in the drug industry, which has similar problems to material science.)

The punch line from independant business analysis disagrees. E.g. (one example)

In 2020, Uber Eats dominated Australia’s food delivery market with a 59.7% share. In the same year, Deliveroo held 17.5% and Menulog 12.1%.

However, by the end of 2021, these numbers had changed slightly. Uber Eats’ market share dropped to 52.9%, Menulog gained market share with 19%, and Deliveroo lost market share, holding just 11.7%

With a dramatically decreasing market share, it’s unsurprising that Deliveroo decided to call it quits.

I'd probably approach 90% confidence with ~2-3 different measurements from different labs showing similar stories. Select from the grab bag of possible experiments that could all collaborate and provide consistency in their stories: specifically things like measuring the critical current, critical magnetic field, high quality electrical resistance in various ways (lots of transport), STM measurements of gaps, ARPES measurements of gaps, XRD showing crystal structures are what we expect that matches the DFT, a study on the domain sizes/effects (since this is relying on a substition at the right place, necessarily I suspect that there will be domain effects / "doping" style things... so how those play out in terms of purity and quality of results will be interesting). There will be a lot to study and characterize, and every extra measurement that is consistent rapidly increases that confidence. I'd say I'd get to "100%" (as close as someone could be) after ~10-20 papers across many different labs and measurements. I'd hope we'd get there in ~3-6 months.

What I'm actually even slightly more excited about is "what comes next" -- not the market part, but the "fast follow science". For instance, in the few years after LCBO and LSCO were found (TC~30K) we quickly found YBCO and BSCCO (Tc~130K). I would expect that we'll find a whole class of these materials with substitution tricks that possibly work, and there will be a whole slew of options for "going to market" with the technology. The door this opens is what is more exciting than the specifics of LK-99 itself in my opinion.

Estimating times, after the fast follow science (0.5-2 years optimistically?) we will hopefully have the actual "we're all convinced this is real, and the technology can start to be applied in real devices". Specifically, after everyone is pretty clear on a lot of the material properties and ways to reproducibly make high-quality crystals, so consistency is clear on measurements... then begins the cycles on how to manufacture high enough quality material at scale that it can actually be applied. (specifically, these materials (assuming they're like YCBO/BSCCO) are superconducting crystals that have grains, alignment issues, are physically brittle, have homogeneity issues, etc.) While each solvable, these are all real engineering and material challenges that increase cost to manufacture, and all of this will probably take time before we suddenly get wide-scale products that use this (this is all assuming it's real, haha, there's still plenty of reason to be skeptical).
Keep in mind that a theoretical model agreeing with possible superconductivity is a pretty weak signal. Even more a DFT one.

Real models for superconductivity take a lot of work to create, it's not something people do for an unverified material, and it's not something you get out of DFT. That paper's agreement is more on the lines of "yeah, all superconductors are grey, and this thing is grey, it can be."

But then, they talked about diamagnetism (graphite-like one, I imagine). Honestly, I have no idea how one could disprove (graphite-like) diamagnetism with that simulation, but disproving it is really good news.

Maybe? I think immigration allows the USA not to be at the bottom anyways (as well as other immigrant friendly countries). But if all the other countries lean in on immigration as their way out, we won't be able to be so picky about what immigrants we take in (e.g. lesser skilled vs. more highly skilled ones). That might cause some problems.

>Assuming this is all true, why is it just now coming to light? Did they just not know what they had?

This is why the calculations by Sinéad Griffin looked so interesting to me: they suggest that the superconductivity depends on an unconventional substitution pattern that might not (in fact should not) occur in most samples of Cu-doped lead apatite. So the active structure was only present in tiny quantities, requiring a long period of trial-and-error optimization.

Again, this is far from proof, but I thought it was at least very curious to have some theory that explains not just a mechanism for superconductivity but also why the samples seem to teeter on the edge of superconductivity so frustratingly.

The replies to my previous post ( https://news.ycombinator.com/item?id=36958419 ) suggesting that flat bands appear simply because copper doesn't belong in that lattice seem inconsistent with the fact that a flat band was not observed when copper substituted at the wrong type of lattice site. If flat bands appear merely because of the unpaired copper electron, they should appear when it is substituted only at Pb {2} sites, but they don't. The appearance of this band structure plus the observance of diamagnetism just takes us from happenstance to coincidence, so we need one more to conclude it is enemy action.

FWIW I don't work in condensed matter physics but I have taken the classes at grad level a few years back. I also should really be doing other things, but this is probably the most fun scientific news cycle since 'Oumuamua at least. (COVID doesn't count as "fun".)
