Science journalism or materials science?


I meant in superconductivity


> U.S. officials declined to disclose the nature of the intelligence, how it was obtained or any details of the strength of the evidence it contains. They have said that there are no firm conclusions about it, leaving open the possibility that the operation might have been conducted off the books by a proxy force with connections to the Ukrainian government or its security services.

There's very little of substance in this article, since it doesn't disclose the intelligence or the officials making the judgement. So it comes across as "x refused to comment, y refused to comment, but we wanted to break the story first so trust me bro"

> Das Kommando soll den Ermittlungen zufolge am 6. September 2022 von Rostock aus in See gestochen sein. Die Ausrüstung für die Geheimoperation sei vorher mit einem Lieferwagen in den Hafen transportiert worden, heißt es. Im weiteren Verlauf ist es den Ermittlern den Recherchen zufolge gelungen, das Boot am folgenden Tag erneut in Wieck (Darß) und später an der dänischen Insel Christiansø, nordöstlich von Bornholm, zu lokalisieren. Die Jacht sei dem Eigentümer im Anschluss in ungereinigtem Zustand zurückgegeben worden. Auf dem Tisch in der Kabine haben die Ermittler den Recherchen zufolge Spuren von Sprengstoff nachweisen können. Nach Informationen von ARD-Hauptstadtstudio, Kontraste, des SWR und der ZEIT soll ein westlicher Geheimdienst bereits im Herbst, also kurz nach der Zerstörung, einen Hinweis an europäische Partnerdienste übermittelt haben, wonach ein ukrainisches Kommando für die Zerstörung verantwortlich sei. Danach soll es weitere geheimdienstliche Hinweise gegeben haben, die darauf hindeuteten, dass eine proukrainische Gruppe verantwortlich sein könnte.


or they expected autocorrect to catch it but it didn't trigger because no period. this is an entirely unnecessary comment lol


> rising to the non-associative power indices ... in the last two decades has been analyzed and does not have a quantum polynomial algorithm that solves it. The problem is called Exponential Congruences Problem.

The author uses similar wording a couple times and it is a little ambiguous? Does "does not have" mean a superpolynomial quantum lower bound has been discovered for this algorithm (or is there a reduction to some other important conjectured complexity theorem)? Or is it just that a polynomial algorithm has not been discovered yet?


Yeah, knowing there is no poly-time quantum algo would be as big as showing P!=NP. If it is "no known" algo, it is well known not to use the stronger wording. Outside of oracle results an "at least this hard result" is a big deal.


There is indeed no excuse for saying "there is no" when they mean "there is no known"

It's almost as bad as saying that NP stands for Non Polynomial time.


It’s probably worth remembering this is a pre-print of the paper. This is the kind of thing that would be corrected when actually published.


It could be a translation error. The author clearly does not speak English as a first language.


no because k is an argument and you have to pre-write k nested loops


> The year-long human trials for Synchron's BCI system have been peer-reviewed by a neuroscience medical journal in Australia(opens in new tab), where the study found the technology safe and signal quality didn't degrade for its Australian patients. The study also concludes that "the favorable safety profile could promote wider and more rapid translation of BCI to people with paralysis." We'll give it about another year before someone's running Doom on it.

could not find full text for free unfortunately

worked for me, but perhaps it's paywalled for some.


The truly wealthy are making much of their money passively, income tax isn't really something they think about. The government would need to increase the estate and capital gains taxes to actually balance/unburden things.

Regardless, I found the anecdotes entertaining.


> The good thing about being a Russian is that you can only blame yourself for this fate.

???


It's their country, they can elect a new government, develop as human being etc.

If they don't well, it's on their own. But if they invade other countries and subjugate other nations to this misery then it's a tragedy - just recall that USSR was not a voluntary union and there are still over 100 different nations oppressed in Russia by this senseless system (see for example Russian Federal republics to get the idea).

Russians tend to forget that and try to excuse the misery they have caused to others by claiming that they too suffered. That excuse is invalid.

PS. All of this was actually explained in the following sentence.


this isn't a materials science article, as it turns out.

if you've already read your three free articles, https://archive.is/VcIcJ

thought it was an interesting perspective, though it's a bit naive or maybe idealistic and it glosses over a lot of the negative harms of some technologies (and factors, economic and otherwise, that motivate these kinds of technologies).


Si and C are both elements. Not bits vs atoms.


> Europeans have a nasty habit of ravaging any black-majority country that tries to build anything.

"Where the heck" did you see the above poster mention restricted?


That post was in the context of asking why black majority countries have done less well than other countries.


fair, my fault for misreading
