- TheRealPomax 3y agoQ: Das Layout sieht Scheiße aus! A: Jo, das ist das historische Default-Layout. solid.
- l33t233372 3y agoMy German is poor. Does this say: Q: The layout is very shitty! A: No, it’s the historically default layout.
- schnuri 3y agoJo translates more to Yes or Yeah
- Tepix 3y agoNo, it says: A: Yes, that's the historic default layout
- omnibrain 3y ago"Jo" is "yupp"
- CoastalCoder 3y agoThanks! I've casually studied German, but I'd never come across "Jo". "Jo" kind of reminds me of Dutch vs. German, where many corresponding words are just slightly different.
- ccppurcell 3y agoJo (pronounced a bit like your without the r sound) is affirmative in lots of European languages, including Finnish and Czech (it's spelled joo in Finnish iirc)
- CoastalCoder 3y agoInteresting. In colloquial (American?) English, "yo" is used to get someone's attention, or to you've heard someone asking if you're present. E.g., "Yo! Doofenschmirtz! You're new inator has been delivered." Or: "Is Phineas here?" "Yo!"
- ccppurcell 3y agoTrue but that's a diphthong, "jo" is just a long(ish) o vowel sound. A lot of English dialects simply don't have an equivalent sound so it's hard to spell it. It's the IPA "o" or close to it. In my accent (south East England) "your" is pronounced almost identically to "jo".
- carabiner 3y agoIn a week there will be a lot of thinkpieces on how the internet got this so wrong. A lot of people just want to believe, full of hope, because their life situations (poverty, housing crisis, hot weather) are so dire.
- whimsicalism 3y agoI haven’t seen this get much play outside of HN and… those are not the problems facing most HN commentators
- carabiner 3y agoI should say that even if it doesn't affect them personally, it creates their worldview when it is 90% of their news. Homeless crisis, war in Ukraine. Why wouldn't you want and allow some positive, apolitical, hopeful story about noble science to consume your attention instead?
- llm_nerd 3y agoWhat would the internet have gotten "wrong"? It's a paper and now people will try to replicate it. Some informed people give their take on why it sounds right and/or wrong, but ultimately they aren't (and can't) verify or debunk it yet pending further investigations. I have zero expertise to give an opinion either way, and honestly the impact of room temperature/pressure superconductors just doesn't seem that overwhelming. Maybe more maglev trains? As with many things now, there are that small set of people who need to pick a "position" early and then stake a part of their ego on it. Which is super weird and destructive, and underlies many of the bad tendencies of the web.
- carabiner 3y agoThis story deserves no more attention than the 10,000 crank papers submitted to Arxiv every day about time travel, prime numbers, antigravity. There is nothing worth replicating. That's what they got wrong.

- whimsicalism 3y agoPushing this higher up, this is the first real expert commentary I have seen.
- yk 3y agoFor context, Fefe is a rather famous German hacker and his blog serves as rumor mill for German nerds. So on one hand I wouldn't trust it that much, on the other hand it is precisely where I would expect knowledgeable people ranting about a bad paper anonymously. (And what they are saying sounds like the type of thing domain experts would pay attention to.)

- ChemSpider 3y agoAnonymous or not, the "MPI guy" explains why he came to this conclusion, and it sounds legit.
- sergiotapia 3y ago"It should look like this" - until these guys made a scientific discovery and now it looks like this other different never before seen graph. This is hardly a proper rebuttal, expert opinion or not. We need these gents to try to replicate the results and then chime in. Otherwise it's just some dudes opinion. At one point the Earth was considered the center of our solar system.
- saberdancer 3y agoPretty sure I read this comment somewhere else (not attributed to Max Planck Institute), I think it was a guy on reddit. Maybe they are the same but could be just copy paste from Reddit.

- jklinger410 3y agoAppreciate whatever this dude is trying to say in their blog, but judging by his writing style and overall presence and demeanor, he doesn't really want to be listened to, does he?
- RC_ITR 3y agoInteresting that the video of levitation isn't mentioned at all in this rebuttal. Assuming the scientists acted in good faith and this isn't a complete scam, maybe we found something else that doesn't conform to our current understanding of superconductors, but does levitate over a magnetic field at ambient temp/pressure.
- tux3 3y agoOne response to the levitation video is that it is hard to distinguish from a non-superconductive diamagnetic effect, which can occur even in not very exotic materials. There are videos of graphite levitating that are circulating, for example.
- tigershark 3y agoNot true. The graphite needs two magnets, not one like in the video.
- trgern 3y agoThe video of “levitation” is one of the things that makes me, a complete ignoramus of the subject matter, skeptical. https://sciencecast.org/casts/suc384jly50n https://sciencecast.org/casts/suc384jly50n All other instances of “quantum levitation” that I have seen has a “locked in” effect: https://m.youtube.com/watch?v=Ws6AAhTw7RA https://m.youtube.com/watch?v=Ws6AAhTw7RA . Whereas the material in this video seems to bounce and warble in a way that appears to me more akin to standard static or magnetic repulsion. Hope I’m wrong.

- tigershark 3y agoHe didn’t even try to explain the levitating video displaying the Meissner effect..
- meepmorp 3y agoThere are non-superconducting materials that exhibit diamagnetism, too.
