I had the same issue with ingesting lots of csv files in a previous version (8.x), though it seemed to be hardware dependent; issue was only on windows not Ubuntu. I think setting …

I think Wolfram came up with some new theory of everything based on hypergraphs a couple of years ago, not sure what the current status is though. I would be surprised if it ever b…

A quick look at the plots make me think this paper is legit and lk-99 is not a superconductor. Nice plots covering down to low temperature, unlike the original lk-99 papers which a…

Well, yes

It's hard to imagine how this could be faked short of digital manipulation, and it seems implausible that it would be a known high TC superconductor because it would warm up too fa…

Thanks for linking someone who knows what he's talking about, very painful to see these DFT papers overhyped as some kind of proof... It proves almost nothing

It's basically an open secret, no one really believes DFT has much predictive power in strongly correlated systems (where relevant electrons cannot be treated as independent). It's…

There are so many bad DFT papers out there because it's cheap to do DFT compared to growing and measuring samples carefully. DFT is notoriously unreliable as a predictive tool in s…

A bit too wordy for me, I wish Landau was around to rewrite books like these, they'd be much shorter. Can we get a LLM to make it happen?

The standard model is basically a description of the fundamental forces, and is usually talked about by particle physicists studying things like the Higgs, quarks, etc. In condense…

Yes, well said.

I've never come across a physicist who used the term "inertia" to refer to any of the common relativistic quantities.

Mass is a Lorentz scalar and thus is invariant; the mass of relativistic particles does not increase as velocity increases. One can say the force necessary to keep a constant accel…

I guess the most prominent counterexample is Germany, which has basically free tuition. They also have different kinds of high schools preparing people for universities or trades, …

I've never seen a number that high in my field, maybe 500 or 600 for the big shots, and even that seems wildly unreasonable to me. Feynman had about 85 peer-reviewed papers over hi…
