Dnešní článek na českém zpravodajském portálu Seznam zprávy připomněl, že mezi subdodavatele patří i pražská firma #Advacam, která dodala radiační sensory HERA (Hybrid Electronic Radiation Assessor). Článek na Seznam zprávách je bohužel za paywallem/cookiewallem, ale tak jako v mnoha jiných případech, vychází z veřejně dostupných informací, které se firmy snaží šířit i formou svých tiskových zpráv: https://advacam.com/czech-footprint-on-artemis-ii-nasa-astronauts-return-to-the-moon-with-prague-made-sensors/ #nopaywall #czech #space #technology #science #artemis2 #europe #praha npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…urnl copak, zkoušíš zmást AI?

Structured as long, numbered thread. There are many first on this #NASA mission. The story about first toiled in deep space seems to be accessible for general public, just like the story about relative diversity of crew, compared to Apollo missions. On of the less understood firsts is the current parking orbit, high ellipse going slightly beyond ring of geosynchronous satellites. This orbit saves energy, because orbital maneuvers are most efficient, when motors are fired in the pericenter of ellipse - you can test this with Kerbal space program. Unmanned missions routinely use these kind of maneuvers, but they are rarely used on manned missions, mostly because there were no deep space manned missions at all for 54 years. No other human exploration activity except deep space flights was paused for such a long time. The great voyages of 15th and 16th centuries were separated by mere decades. Early balloon flights were incredibly dangerous, but people kept trying. The rationale for sending small, automated probes is overwhelming, but the ability to move somewhere as human being is still important part of human experience: we are not just information processing machines. We need to learn to move also our bodies. #artemis #mannedspaceflight #space #moon npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…3dtp to by se tam musel vydat nějaký odborník, no... @nprofile…kuv3 npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…pjcv poznámka: takhle blízko k povrchu Měsíce se ovšem Artemis II nepodívá... poletí daleko výše, nejvíc se to do bude blížit dráze Apolla 13. Po podobné dráze by také létal sovětský 7K-L1 (Zond), do kterého si ale nikdy netroufli posadit kosmonauty (diskutabilně ani poslední stupeň těsně neměl dost výkonu na to, aby loď s kosmonauty unesl, takže ti by možná bývali muset přestoupit na oběžné dráze, což ale tehdy ještě neměli natrénované...) To, že po všech těch letech nemá kombinace SLS+Interim cryogenic stage+Orion dostatečný výkon na to alespoň se navést na dráhu kolem Měsíce, je trochu trapas. Tenhle výkon měl poskytnout Exploration upper stage, jenže ten byl zrušen. Proto Artemis III bude pouze zkouška spojení s přistávacími moduly na nízké oběžné dráze. A jak se vlastně k Měsíci dostane Artemis IV, to mi přijde, že je trochu ve hvězdách... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…k6sx it not so much efficient, but you are right, that the Oberth maneuver make it more efficient, than Apollo. I believe Artemis 2 crew are going to be first people to circle Earth on nearly GTO orbit, which is interesting. Actually, the trajectory feels pretty safe, because if the service module fails during low perigee parking orbit, this orbit would probably naturally decay after few days. And if the service module fails after TLI, the free return trajectory would return capsule to Earth splashdown, just perhaps not very precise... I am sure ISRO would do it using multiple precise apogee raising (Oberth) maneuvers, as they do with all their lunar and interplanetary missions 🙂 @nprofile…600e npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…0zu5 GMT+0 je spíš Londýn, ne? npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…0zu5 ne, ale asi bych měl zajít, hmm. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…5rsp to be fair, Kazakhstan is actually mostly safe country, perhaps "contains areas with higher security risks", but otherwise is really mostly very friendly. But the safety division of Europe is ridiculous, of course. Pure propaganda. There may be occasional no-go zones, but they are as likely in Balkans countries, as in Western Europe. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…guzq můžeš si mě najmout jako kurýra a doručím mu ji na kole. Dnes mám celkem čas... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…0zu5 přepínám na soukromé, je to česká konverzace pod anglickým tootem. u mě jsou na první místě environmentální důvody - uhlíková stopa spotřeby energie - ale v aktuální situaci nadcházející energetické krize a Íránu blokujícího Hormuzský průliv je to i bezprostřední bezpečnostní důvod: pálí to plyn, plyn nebude nejbližší zimu. Některý lidi si nebudou moc dovolit topit. Jiným názvem pro AI může být "Boltzmanův stroj". Je to v podstatě termodynamická katastrofa. Je to zásadní kognitivní problém mě jako jednotlivce v tomhle vesmíru: ostatní lidi se předstávají i v naprosto teoretické rovině zajímat o mě (co taky se mnou: stárnoucí dědek... netvořím, nepublikuju...) Obecně vzato, odmítám si připustit, že myšlení je jen nějaká lepší ruleta s řazením toho, jak slova následují po sobě. Obvinil jsem Tě, že některé problémy, kterými jsi zaujat, jsou "teologické" (měl jsem asi říct "scholastické"), ale s AI mám zase já svůj problém. Pro mě technologie koneckonců byla hluboce mytologická cesta k jiným lidem: prostě postavím loď Argo a vypravím se za zlatým rounem (solární kolo toto mělo být, ale úplně nebylo - zaujalo, ale ne tolik a nenašel jsem pro to zaujetí žádný užitek...) Technologie, která je cestou tak nějak jen sama k sobě a svým vlastním smyslem, je dystopickým varovným příběhem mnoha kultur, mnoha sci-fi. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…8pxh one dimensional, of course. 2 dimensional is "political compass", which is kind of mind trick on its own :-) npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…3a68 sorry, of course, one dimensional npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' https://www.esa.int/Science_Exploration/Human_and_Robotic_Exploration/Europe_s_engines_powering_Artemis_II The European Service Module has three types of engines that work together, each with a specific role during the mission. A single main engine delivers the large changes in speed needed to send Orion towards the Moon. It is supported by eight auxiliary engines, which are used for orbital corrections and can back up the main engine if needed. For precise control, 24 smaller reaction control system engines, arranged in six pods, are used to rotate and orient the spacecraft. #europe #esa #space #mannedspaceflight #artemis npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…8pxh well, besides facts, there are still feelings, and you can't really educate people about feelings and emotions, because they just feel certain way. Feelings can be manipulated, which is perhaps not always good, but there is also the tradition of catharsis through art. I am not sure we can have perfectly emotion-free public which is just educated and operates solely rationally using facts (perhaps, this is something everybody supposes AI does.... but AI just wildly tailors responses in the state space of all possible conversations, based on the small nuances in prompts... and there is lot of feedback, and so). Anyway, my own feeling is, that we need something to replace AI. There doesn't need to be much technology involved, but existing communication tools and media may be involved. It just not going to go away, it is taking too much space, when the bubble bursts, something has to fill this space. We really need to start thinking about post-singularity life. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…pyck yes, this is why I have so many questions. Basically, I don't really like like extreme views, but I think Xitter manipulates people generally far beyond far right (or at least - attempts to do so). But the basic fact, that AI chatbots can manipulate people's opinions, just like algorithms on social networks surely did, is alarming. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' I have so many questions about following chart. While I consider turning people towards rational, critical, moderate attitudes to be generally good thing, as the extreme views are often unsustainable, I also consider two-dimensional political spectrum to be rather insufficient, as there are more dimensions to human experience in society, than one. So: this chart basically says, that AI chatbots manipulate people's opinions. Supposedly, in a good way (towards middle) but still... it means, that it manipulates them. Like old media, like new media. But... do we really need to burn so much fossil fuels to explain people, that climate change is not hoax and therefore, we perhaps should not burn so much fossil fuels? 🤔 (I haven't read the article, because it is behind paywall, so these are may own comments) #ai #noai #ft #politics https://f.cz/system/media_attachments/files/116/322/883/891/136/583/original/b79e94050e5c96f2.jpg npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…9wwv tak to, že Hřib kope za developery je asi uvěřitelné... ale říkalo se to i Čižínského Praze sobě... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…9wwv například? npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…9wwv no ok ale teď k té Komrskové... o co tam teda jde? ona byla nějaká zásadně světlá postava, kterou se Hřib snažil za každou cenu "odstavit"? @nprofile…v2fx npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…jh4w I think this is kind of revenge to EU. It said "let's standardize USB connectors to USB-C". Which was not so bad idea. But corporations somehow invented revenge: "ok, so we are now expected to use this connector for EVERYTHING? Hold my beer!" Enforcing certain connector should definitely include prohibiting its use for anything else. "High voltage" above 50V is actually quite regulated, the power sockets, or so. The problem with regulation is that once you start, you have to enforce it and prohibit compliant-looking, but actually killer devices like this charger... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…rtec Za 20 let budou IPv6 používat všichni, o tom nepochybuji... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…qvfs jo, mluví se spíš o těch "střídačích", co jsem tak pochopil.

Stejně není bezpečné, aby chodci zabírali chodník celý až těsně po kolejiště. Oddělit je od MHD pruhem s přednostní cyklistů, kteří mají vůči MHD menší relativní rychlost, je i v zájmu bezpečnosti chodců... ti by se stejně měli držet spíš zábradlí, docela hrozí, že třeba pobíhající děti by mohly omylem do toho kolejiště zabloudit, takže směřovat provoz chodců co nejdál od kolejí je pud sebezáchovy všech (kdyby to byl vlak, bude tam plot, ale efektivně se tramvaj chová jako neoplocený vlak, nedávno byl v Břevnově smrťák...) Využití cyklopruhu jako nárazníkové zóny mezi MHD a chodci mi přijde přirozené. Jediné, co mi napadá, že za široký smíšený pruh bojovala nějaká bruslařská lobby. Jako cyklistovi by mi vyhovovalo vizuální rozdělení půl napůl - stejně by tam bylo 2m pro všechny - myslím, že současný stav chtěl někdo, kdo chtěl na obou chodnících obousměrný provoz kol, ale takový charakter provozu se hodí spíš na nějaké pěší zóně či obytné ulici, ale půlkilometrový most je dálková komunikace a dá se předpokládat, že tam cyklisti budou jezdit plnou rychlostí, a ne jako ve smíšené zóně. Tohle není první podobná demence - jsou i horší, třeba v Hradci most cyklostezky přes Labe končí záludnýma neoznačenýma schodama (jen v části směrů, ovšem!) bez jakéhokoliv zábradlí, ohraničujícího sloupku, nebo tak.

No amount of money would force locals to voluntary agree with it, so it is waiting for some international solution in the future, which just won't happen during our lifetimes. So the actual result is kind of "medium time storage", were the spent fuel is waiting for final decision if it is going to be reprocessed or "permanently" stored. Still, because the waste is already here, there is no significant difference in generating little more or little less. It is sad to say, but true. Closing existing (modern) reactors in Bavaria was perhaps tactical mistake, because it made CDU to loose votes to AfD instead of Greens (and even most of Green voters were not really very radical about closing the two remaining viable power plants, because they also don't like coal mines and so). Nuclear power is strategical mainly for Finland and Sweden, because these two countries have really arctic conditions inland during winter (Swedish people solved this by spending winters in Thailand :-)). Norway is different story, because they have lot of hydro power: lot of mountains close to the sea, lot of rain. Poland wants nuclear power to power industry and also it is located quite in the north. My country has certain mix of problems: high elevation and inland location means, that our winters are harsher, then in Germany or Netherlands We are also quite far in the north and the average insolation through the year is not great, especially form November to February there is little to none solar power.

I seriously doubt so, but again, I am not expert... just maybe hard science fiction fan, or something like that. But there is still this "theory of mistakes", that when you are trying something, you can discover something completely different... But the problem with fusion is mostly engineering... and perhaps few other problems, which are not just engineering, but rather extremely complex math, which you probably won't figure out without trying. So you iterate and try to make it slightly larger and different... so perhaps more teams in the world should be doing this, and not something else, but while it is applied research, you are still not guaranteed to achieve useful results. So the activity kind of reminds me of ancient temple building. It does not automatically mean, that it is bad, because centuries ago, building temples was simply the way to organize society around some common activity, not directly practical (I am definitely not the first one, who has this feeling). Probably better, than fighting! Do I want our everyday lives to rely on something as complex, as fusion energy? (or LLMs, by the way?). I am really not sure. I would rather trust something more simple, maybe. Solar panels and batteries are relatively straightforward and seem easy to understand. But they are not enough during the winter.... and of course, general computing seemed simple to me. But people wanted something more, than general computing could offer.... So perhaps: the basic research, which really does not threat to become the new key technology, on which everything relies, is not such a bad idea... I never said, that I am against basic research (even if myself I live and work outside of science and academia...) npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…54eq @nprofile…dw04 This is complicated. I did not say "basic science can be trusted not to predict anything". I just believe, that there are certain fields of research, which are generally not expected to turn into applied research and technology. Fusion technology is special example, one of my favorites. I am 52 years old. But since my 12 years or so, fusion was available in 30 years. The basic principle works... somehow. For some time. There was tremendous amount of both theoretical and practical work done. Except... it does not seem to be scalable anytime soon. It is like trying to power steam locomotive with Heron steam engine: in theory, it should work. It is even kind of steam turbine! But in fact, the actual steam engine was built quite differently. So you can have knowledge, which is basically right, even known for centuries, but still get no practical results. The popular summary, that inside fusion reaction, there would be "environment like inside Sun" is oversimplification: Sun is huge, but the average density of fusion reactions inside is just fraction of what would be required inside tokamaks. So the required environment would be actually much more extreme. It works in theory, but the engineering might never be sufficiently advanced - who knows. But the popular belief is, that it may be the only possible future. So the society is just giving away certain constant, but probably not sufficient, amount of resources to fusion research, always not enough, so the they slowly crawl towards better and better results, which definitely prove, that it works... but at the same time, practical application is always 30 years in the future. You would also activate spent reactor vessels with neutrons, while turning them into heat... not really long life nuclear waste, but still... So fusion is good question: if we put more money into fusion, than manned spaceflight or let's say, particle accelerators, would we finally get it working? npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…az0m no #mosstodon hashtag?

The very birth of modern science from alchemy was series of mistakes... they were following some prescribed rituals, thought to be magical, but they messed up and invented stuff like eg, phosphorus. Also, mandragora was maybe ginseng and it really kind of prolongs life... but doesn't always grow on gallows hill.. So, if some next generation of science emerges, it may very well be results of mistake, done by current AI alchemy crowd. At least, the face similar problem: they spent whole lot of funding to deliver some promised miracle, sometimes even literally same, as alchemists did... and in the process, they invent and share various tricks, and even made the mistake of inventing chemistry.... So it seems to me to do something with a chance of new discovery by mistake, which can happen even by trying manned spaceflight. On the other hand, investing into basic research, which can be trusted to really not even predict anything, is kind of strange game... Eg., from the point of view of military technology, it is absolutely safe to fund string theorists, because they are not likely to produce any terrible "string bomb" or something like that :-) You don't even risk creating another universe by mistake, or so: only lot of very nice papers and diagrams and equations are going to be published, with no dangerous real world consequences (which is not such a bad societal outcome... kind of art, maybe...) So you can choose to do something, which is guaranteed to NOT give you any breakthrough, not even if you do it wrong (think about preserving some sacred texts in monastery) ... or you can do something, where the results can be random and poorly understood. (like eg. Podkletnov or so...) Anyway: if something doesn't work, I don't think it is because "they are hiding it from us", but rather because not enough mistakes were made... yet :-) npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…54eq @nprofile…dw04 as for the string theory... I really understand just the very basic idea (and maybe not even enough) but it somehow reminds me of the original idea of "asking AI about how the world works and not really needing empirical data". But of course... eg. atomic bomb was basically pure theory, gone "boom" when implemented. This was also the moment, when science started to be somewhat suspicious activity... There were many attempts on trying to fugure out "how the things must work". Theory of knots in the 19th century turned out to be dead end... and yet they were quite sure, that they will predict properties of atoms! (The knots theory and string theories seem to be distant cousins). You know, I am maybe more informed about the history of science ("wikipedia syndrome"), than recent developments :masto_wink: I am basically very anti-LLM, because we can expect lot of people "educated" by talking with chatbots... and they would believe crazy things. But sometimes, there really may be occasional "nobody told them, that it can't work" effect. Sometimes, you really need certain (but not too high) level of ignorance, that something is generally considered impossible (but not too much and not as repeated attempts and not when people's life are in danger...). But also, scientific discoveries and technological inventions are not the same thing... but public likes to confuse them and it is also often misused as reason for funding... which is really oversimplification... like, lack if understanding, how society works... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…54eq @nprofile…dw04 well, I don't generally want to argue. I am not really scientist, partly for dumb reasons, which I regret now, partly simply because the required decisions would be needed at age, when I was not ready for it, may it was about the era our country was going through... I was too much hypnotized by "informatics" taking over everything. It was the mindset, which finally resulted in current LLM bubble, RAMageddon, etc. But I did not have enough concentration and focus anyway. Who knows, what could I focus on, if there was no programming around. But I am fan of basic research and scientific knowledge. The "manned spaceflight vs. science funding" is mostly artificial political dilemma, and it could be compared to competitive sports vs. availability of some sport activity for public. There can be synergies on many levels. You could argue, that particle colliders suck funding from other fields of basic research. Sometimes you just bet on certain direction of research and sometimes you spend money finding nothing. Eg. manned spaceflight, while basically just publicity stunt, would be probably better investment, than some attempts on dark matter detection. Maybe better publicity stunt, than "please give us money, so we can find nothing and prove it". I mean, there are worse scams, but sometimes, finding nothing with high level of signifixanxe is not the best message for general public, while cool space selfie may be much better message :masto_wink: I don't want to join the general speticism about physics, which may be even somehow encouraged by climate change deniers. There are some parts of physics, which can be locally tested and are well known and probably won't be disproved any time soon. But at the same time, I would definitely invest into fine tuning of technologies for storing energy, instead of building larger collider. Sorry. There are real technological needs with political consequences... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…54eq @nprofile…dw04 I am fan of manned spaceflight, but maybe, the funding should be different from science. Manned spaceflight is more or less extrapolation of great voyages, mountain climbing, polar expeditions, and such. I would compare it rather with great sport events... excepts is too ambient (most of the time) and the risks are of different type then risks undertaken in sports, so the funding model of great sport events would not work. It attracts attention of few people and in different way. The TV show paradigm is definitely more worth replacing, than science. But when talking about understanding universe, both large and small... you know, I am not scientist, just huge fan of science and history of science, but on amateur basis. It is exciting to invent concepts about how the universe works and be able to do something new, based on these new concepts. Sometimes, save lives. The intuition, that there may be more to learn when looking at night sky at higher and higher resolutions and more frequency bands, than by smashing particles together at higher and higher frequencies is maybe wrong, who knows. Definitely, trying to guess things without any input data means doing pure math. You can construct mathematical objects without input data... but why? There was this strange case of string theory in physics, which thrived even without predicting any observation or suggesting any experiment. No future collider would prove or disprove this. Some theories are too far off.... I feel like there are two major approaches in natural sciences: one is this belief, that if mathematical object is possible, it simply exists somewhere in nature (so we see all this spirals and ornaments in plants, and so on) and the second approach is statistical analysis of gathered data. Human language is not mathematical object, but LLM AIs somehow treat it as if it was. I seriously doubt, that searching through "all possible conversations" can replace science... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…xp6m @nprofile…dw04 when talking about idea of "pure knowledge", it is very Platonian, and according to Karl Popper, Platon's ideal of ideal government could be considered as an archetypal fascist state (on the other hand, Platon had some basic ecological thinking ahead of his time). So we somehow re-run the classical discussions of ancient Greek philosophers again and again. While the "pure knowledge" school invented almost nothing in the field of pure knowledge, the mathematics and natural science, which built on the work of Erastothenes, Archimedes or Euclides, gave us all the technical tools, using which Elon now wants to return... to search for "pure knowledge", again. At some moment, what used to be practical research, can turn into blindly followed rituals, workshops into temples, and so. I am afraid, that science is not immune to this process (the large colliders may be actually temples, we just don't see it). But while science may fall into this trap, with all the grace and glory of huge, timeless, established religion, the AI already is thriving as kind of pagan cult worship, based on ritual sacrifices. The brute search of possible state space works only for system, where the models are precise enough, which is never possible for non-linear systems. Somehow, Elons reminds me of the famous 19th century patent office. Just because he ran out of creativity, is stuck in his singularity mindset and cannot imagine any new discovery or progress by anything else then his AI, it doesn't mean, that it makes any sense. Still, the AI is somehow the ad-absurdum extrapolation of the "statistical" era of science, and there is about to be any new era, not AI based, it will have to be different. The LHC is itself is based on the way of thinking and data processing, which somehow, when applied on other type of data, gave rise to LLMs... so if we consider LLM AI a dead end, so... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…tup9 tip: se správně zvolenými hashtagy by ty fotky našlo daleko víc lidí... npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…mare no jo, tohle je klasický trik. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…dw04 well, for analysis of ever increasing amount of astronomical data, some kind of automation is needed anyway. So maybe it would be better use of AI, than all this chatbot nonsense. The huge colliders are special case, that now there is AFAIK no special prediction in physics, which can be confirmed or falsified at higher energies. Somehow it is probably not the direction to find any new physics (which would be cool). Also the dark matter detectors are somehow infamous as spending huge amount of money for (predictably) finding nothing. The situation in astronomy is very different and of course we need new telescopes and new ideas for telescopes. Lot of them would have to be placed in space, probably. So, somehow the discussion "what next in science" makes sense, and I would not probably bet on particle colliders to be the right answer. Still, over-relying on LLM-líke AIs si ridiculous. Of course, science needs new (not necesarily "more") empirical data and also, for huge amounts of data, some automation to process them. npub1g5p4mh53h62tkmghk5vx6ee85es7dw84qpud58sm2chvyarnd2asjcwnzc Chao-c' @nprofile…kgrc ale tak já to vím už dlouho, ale včera jsem to zjisti znova. To já zase nemám nějaká zásadní prozření, co by se neopakovala :-)
