Speaking of isolated elements as of a source of differences is completely off, they are present in compounds and compounds have properties completely different from their building blocks. HS example is sodium - highly reactive, capable of producing explosions on contact with water, and chlorine...

I recently tested several AI detectors on several texts I was 100% sure about their source and results were quite random. I am not saying flagging texts won't work at all, and definitely now and then I see phrases/ways of communicating things that make me think "AI", but this is a hard nut to crack.

More precisely: it wasn't detected today but earlier and yesterday there were two patches published. I assume @Greg Bernhardt is aware and applying patches is rather straightforward (there were some initial hiccups, after the info was made official I had to wait two hours before patches became...

Yep. At some point cows lack of sphericity becomes a dominant factor.

Won't give you citations, but I am more than sure I read about the idea years ago - without any conclusions though, just as a speculation. I started to wonder though: many reactions tend to "keep" chirality of reactants (or to reverse it, depending on the mechanism, but that means they still...

No. And generally speaking: their discovery doesn't "solve" anything. It proves the solution can exist and can be rooted in a natural process. But none of the examples they found seems "practical" - as in "possible to appear in a typical mix of naturally existing reagents we expect to see in...

It is experimental: when predictions calculated using simplified model stop predicting right, you need to switch to the less simplified model.

Yes, and that makes me doubt this is really the answer we are looking for. Still, an interesting system, and definitely proves there is no need for magic nor divine intervention :wink:

This is basically kind of a process I remember being suggested even before their works (I learned about it in the early eighties, and I strongly doubt it was a fresh one then). The idea is that of a self-enforcing change: imagine you have a bag of black and white marbles. You draw three at...

In Polish "paragraf" is very rarely used in the context of a typical text (we call part of a text "akapit" there), "paragraf" most often relates to legal context (section or article of act or contract).

Note: this is most likely happening outside of PF, on cloudflare servers. PF was under bot/scrapper attack some time ago and Greg added cloudflare as an intermediate service that blocks DDoS attacks. Hard to say what their algorithms detected, could be they occasionally block IP ranges, or...

My knowledge about infinities is infinitesimally small, but there is a chance answer depends on what kind of infinity you started with. Was it ##\aleph_0##? ##\aleph_1##? Something else?

Cloudflare FTW, bots killed CF for several weeks last year, IP bans were not enough.

Note: USB-C can work at high powers IF both sides (sender and receiver - power supply and the laptop in your case) agree on parameters. In theory there is no risk of getting something destroyed, you can safely connect any two USB-C devices, they should agree on who is supplying and who is...

"Noble" in this context is a very vague concept, with no real, well defined meaning. Silver is considered a noble metal, yet it easily tarnishes in the presence of compounds containing sulfur happy to react with it (so more like sulfides than sulfates).
