There is no obvious path between todayâs machine learning models â which mimic human creativity by predicting the next word, sound, or pixel â and an AI that can form a hostile intent or circumvent our every effort to contain it. Regardless, it is fair to ask why Dr. Frankenstein is holding the pitchfork. Why is it that the people building, deploying, and profiting from AI are the ones leading the call to focus public attention on its existential risk? Well, I can see at least two possible reasons. The first is that it requires far less sacrifice on their part to call attention to a hypothetical threat than to address the more immediate harms and costs that AI is already imposing on society. Todayâs AI is plagued by error and replete with bias. It makes up facts and reproduces discriminatory heuristics. It empowers both government and consumer surveillance. AI is displacing labor and exacerbating income and wealth inequality. It poses an enormous and escalating threat to the environment, consuming an enormous and growing amount of energy and fueling a race to extract materials from a beleaguered Earth. These societal costs arenât easily absorbed. Mitigating them requires a significant commitment of personnel and other resources, which doesnât make shareholders happy â and which is why the market recently rewarded tech companies for laying off many members of their privacy, security, or ethics teams. How much easier would life be for AI companies if the public instead fixated on speculative theories about far-off threats that may or may not actually bear out? What would action to âmitigate the risk of extinctionâ even look like? I submit that it would consist of vague whitepapers, series of workshops led by speculative philosophers, and donations to computer science labs that are willing to speak the language of longtermism. This would be a pittance, compared with the effort required to reverse what AI is already doing to displace labor, exacerbate inequality, and accelerate environmental degradation. A second reason the AI community might be motivated to cast the technology as posing an existential risk could be, ironically, to reinforce the idea that AI has enormous potential. Convincing the public that AI is so powerful that it could end human existence would be a pretty effective way for AI scientists to make the case that what they are working on is important. Doomsaying is great marketing. The long-term fear may be that AI will threaten humanity, but the near-term fear, for anyone who doesnât incorporate AI into their business, agency, or classroom, is that they will be left behind. The same goes for national policy: If AI poses existential risks, U.S. policymakers might say, we better not let China beat us to it for lack of investment or overregulation. (It is telling that Sam Altman â the CEO of OpenAI and a signatory of the Center for AI Safety statement â warned the E.U. that his company will pull out of Europe if regulations become too burdensome.)

đ§”Meet 15 Jewish Nobel Prize Winners Who Changed Historyđ§”
The Jewish population constitutes just 0.18% of the world (15.3 million out of 8.2 billion), yet approximately 20-30% of Nobel Prize winners in fields like Physics, Chemistry, and Medicine are Jewish. This incredible fact highlights the Jewish community's historic contributions to humanity.
Letâs meet just 15 of the over 200 Jewish Nobel Prize winners.
1/Â Albert Einstein (1921, Physics).
Einstein was born in Germany to a secular Jewish family. His groundbreaking discovery of the photoelectric effect laid the foundation for quantum mechanics, earning him the Nobel Prize.
âȘ His theory of relativity (E=mcÂČ) reshaped our understanding of gravity and spacetime.
âȘIn 1933, Einstein fled Nazi Germany to the U.S., where he became a vocal advocate for civil rights and Zionism. âȘHe helped inspire the Manhattan Project but later became an advocate for nuclear disarmament.
2/Â Niels Bohr (1922, Physics).
Born in Denmark to a Jewish mother, Bohr revolutionized atomic physics.
âȘHis Bohr Model showed electrons orbit the nucleus in distinct energy levels. âȘDuring WWII, Bohr worked on the Manhattan Project after escaping Nazi persecution. âȘBeyond science, Bohr advocated for global cooperation and peaceful nuclear energy use.
3/Â Shmuel Yosef Agnon (1966, Literature).
Born in Galicia (modern-day Ukraine), Agnon immigrated to Ottoman Palestine in 1908.
âȘHis novels and stories delve into Jewish tradition, spirituality, and the tension between modernity and faith. âȘHis acclaimed works include A Simple Story and Only Yesterday. âȘAgnonâs Nobel solidified Hebrew literature's global recognition.
4/Â Rosalyn Yalow (1977, Medicine).
Yalow, born in New York to a Jewish family, co-developed radioimmunoassay (RIA), a groundbreaking technique to measure hormones in blood.
âȘHer work revolutionized the diagnosis and treatment of diseases like diabetes. âȘDespite gender biases in science at that time, she became the second woman to win the Medicine Nobel.
5/Â Baruch Blumberg (1976, Medicine).
Blumberg, a Jewish-American physician, discovered the Hepatitis B virus and developed its vaccine.
âȘHis research saved millions from liver disease and cancer.
âȘBlumberg also served as the first director of NASAâs Astrobiology Institute, exploring lifeâs origins in the universe.
6/Â Lev Landau (1962, Physics)
Born in Baku, Azerbaijan, to a Jewish family, Landau made ground-breaking contributions to condensed matter physics and quantum mechanics.
âȘHis groundbreaking work on superfluidity explained the behavior of liquid helium at extremely low temperatures. âȘLandau also developed the "Landau-Lifshitz equations," foundational in describing ferromagnetism. âȘKnown as a genius in theoretical physics, his "Landau Levels" remain crucial in quantum mechanics.
7/Â Richard Feynman (1965, Physics).
Feynman, born to Jewish parents in New York, shared the Nobel for his work in quantum electrodynamics (QED).
âȘKnown for his brilliance and humor, he revolutionized particle physics with "Feynman diagrams." âȘHe contributed to the Manhattan Project and inspired countless scientists through his lectures and books like Surely Youâre Joking, Mr. Feynman!
8/Â Elie Wiesel (1986, Literature).
A Romanian-born Holocaust survivor, Wiesel wrote Night, a searing memoir of his Auschwitz experience.
âȘHe dedicated his life to Holocaust education and combating hatred. âȘWieselâs Nobel recognized his literary contributions, ensuring the horrors of the Holocaust were never forgotten.
9/Â Herbert Hauptman (1985, Chemistry).
Hauptman, a Jewish-American mathematician, co-developed direct methods for solving crystal structures, revolutionizing crystallography.
âȘHis work paved the way for advances in drug design, enabling scientists to develop life-saving medications. âȘHauptmanâs methods remain foundational in understanding molecular structures in biology and medicine.
10/Â Robert Aumann - Yisrael Aumann. (2005, Economics).
An Israeli-American mathematician, Aumann revolutionized game theory, analyzing strategic interactions between rational decision-makers.
âȘHis work, particularly on "repeated games," has applications in economics, military strategy, and even evolutionary biology. âȘAumann is an observant Orthodox Jew and has been a vocal advocate for Israel's security and has connected his mathematical insights with the Talmudic concept of fairness and justice. He often reflects on his Jewish heritage in his work and public speeches.
11/Â Aaron Ciechanover (2004, Chemistry).
Ciechanover, born in Haifa, Israel, discovered the ubiquitin-mediated protein degradation system.
âȘThis mechanism explains how cells identify and destroy faulty or damaged proteins, which is essential for maintaining health. âȘHis findings have significant implications for treating diseases like cancer, Alzheimer's, and Parkinson's.
12/Â Avram Hershko (2004, Chemistry).
Hershko, born in Hungary and a Holocaust survivor, worked alongside Ciechanover on the ubiquitin system.
âȘHis research showed how proteins are tagged for destruction, which is vital for cellular health. âȘHershkoâs journey from surviving the Holocaust to becoming a Nobel laureate highlights the resilience and brilliance of Jewish scientists.
13/Â Daniel Kahneman (2002, Economics).
Kahneman, born in Tel Aviv, is a psychologist whose work transformed economics.
âȘHe co-authored Thinking, Fast and Slow, exploring how cognitive biases affect decision-making. âȘHis prospect theory explained how people assess risk, challenging classical economic theories of rationality.
14/Â Ada Yonath (2009, Chemistry).
An Israeli crystallographer, Yonath is celebrated for uncovering the 3D structure of ribosomes, the cell's protein factories.
âȘHer work advanced the development of antibiotics targeting bacterial ribosomes, combating antibiotic resistance. âȘYonath is the first Israeli woman to win the Nobel Prize in Chemistry.
15/Â Saul Perlmutter (2011, Physics).
An astrophysicist from Berkeley, Perlmutter co-discovered that the universeâs expansion is accelerating due to "dark energy."
âȘHis work confirmed the existence of this mysterious force, which makes up about 68% of the universe. âȘPerlmutterâs groundbreaking discovery led to a wave of new theories and observations in cosmology, changing how we understand the cosmos and our place within it.
Conclusion.
Of the 976 individual winners of the Nobel Prize and the Nobel Memorial Prize in Economic Sciences from 1901 through 2024, at least 217 have been Jews or people with at least one Jewish parent, an astonishing 22% of all recipients.Â
This amazing achievement underlines the huge contribution that the Jewish community has made to world progress in a wide range of areas, from science and medicine to literature and economics.Â
With only 0.2% of the world's population, Jewish people have continued to shape and inspire the world with intellectual perseverance and innovation, thus leaving a lasting legacy for future generations.Â
Correction *Jewish population is at 15.8 million.Â
Correction: Wiesel won for peace.Â

hello! im just finishing up my read of structures of scientific revolutions, which has genuinely been very useful and shifted my understanding of science in a way being around people doing scientific research all day really didn't! i don't have a liberal arts education so i would love to get a sense of (a) what else of the philosophy / history of science canon is worth reading in the original (b) standard review papers or introductory textbooks and (c) critiques of the canon. i understand this is a big ask ofc, so feel free to point me to good depts / syllabi from good courses. thanks :)
yessss such a fun question >:) so, the thing that was so great about 'the structure of scientific revolutions', which i'm sure you've picked up on, is that kuhn pushed historians and philosophers of science to challenge the positivist model of science as a linearly progressive search to 'accumulate knowledge'. the idea of a 'paradigm shift' was itself a paradigm shift at the time; it was an early example of a language for talking about radical change in science without giving into the assumption that change necessarily = 'progress' (defined by national interests, mathematisation, and so forth). this is still an approach that's foundational to history and philosophy of science; it's now taken as so axiomatic that few academics even bother to gloss or defend it in monographs (which raises its own issue with public communication, lol).
where kuhn falls apart more (and this was typical for a philosopher of his era, training, and academic milieu) is in the fact that he never developed any kind of rigorous sociological analysis of science (despite alluding to such a thing being necessary) and you probably also noticed that he makes a few major leaps that indicate he's not fully committed to thinking through the relationship between science and politics. so for example, we might ask, can a paradigm shift ever occur for a reason other than a discovered 'anomaly' that the previous paradigm can't account for? for instance, how do political investments in science and scientific theories affect what's accepted as 'normal science' in a kuhnian sense? are there historical or present cases where a paradigm didn't change even though it persistently failed to explain certain empirical observations or data? what about the opposite, where a paradigm did change, but it wasn't necessarily or exclusively because the new paradigm was a 'better' explanation scientifically? how do we determine what makes an explanation 'better', anyway, especially given that kuhn himself was very much invested in moving beyond the naĂŻve realist position? and on the more sociological side, we can raise issues like: say you're a scientist and you legitimately have discovered an 'anomaly'. how do you communicate that to other scientists? what mechanisms of knowledge production and publication enable you to circulate that information and to be taken seriously? what modes of communication must you use and what credentials or interpersonal connections must you have? what factors cause theories and discoveries to be taken more or less seriously, or adopted more or less quickly, besides just their 'scientific utility' (again, assuming we can even define such a thing)?
again, this is not to shit on kuhn, but to point out that both history and philosophy of science have had a lot of avenues to explore since his work. note that there are a few major disciplinary distinctions here, each with many sub-schools of thought. a 'science and technology studies' or STS program tends to be a mix of sociological and philosophical analysis of science, often with an emphasis on 'technoscience' and much less on historical analysis. a philosophy of science department will be anchored more firmly in the philosophical approach, so you'll find a lot of methodological critique, and a lot of scholarship that seeks to tackle current aporias in science using various philosophical frameworks. a history of science program is fundamentally just a sub-discipline of history, and scholarship in this area asks about the development of science over time, how various forms of thinking came into and out of favour, and so forth. often a department will do both history and philosophy of science (HPS). historians of medicine, technology, and mathematics will sometimes (for arcane scholastic reasons varying by field, training, and country) be anchored in departments of medicine / technology / mathematics, rather than with other faculty of histsci / HPS. but, increasingly in the anglosphere you'll see departments that cover history of science, technology, and mathematics (HSTM) together. obviously, all of these distinctions say more about professional qualifications and university bureaucracy than they do about the actual subject matter; in actuality, a good history of science should virtually always include attention to some philosophical and sociological dimensions, and vice versa.
anywayâreading recs:
there are two general reference texts i would recommend here if you just want to get some compilations of major / 'canonical' works in this field. both are edited volumes, so you can skip around in them as much as you want. both are also very limited in focus to, again, a very particular 'western canon' defined largely by trends in anglo academia over the past half-century or so.
philosophy of science: the central issues (1998 [2013], ed. martin curd & j. a. cover). this is an anthology of older readings in philsci. it's a good introduction to many of the methodological questions and problems that the field has grown around; most of these readings have little to no historical grounding and aren't pretending otherwise.
the cambridge history of science (8 vols., 2008â2020, gen. eds. david c. lindberg & ron numbers). no one reads this entire set because it's long as shit. however, each volume has its own temporal / topical focus, and the essays function as a crash-course in historical methodology in addition to whatever value you derive from the case studies in their own right. i like these vols much more than the curd & cover, but if you really want to dig into the philosophical issues and not the histories, curd & cover might be more fun.
besides those, here are some readings in histsci / philsci that i'd recommend if you're interested. for consistency i ordered these by publication date, but bolded a few i would recommend as actual starting points lol. again some of these focus on specific historical cases, but are also useful imo methodologically, regardless of how much you care about the specific topic being discussed.

i would also say, as a general rule, these books are generally all so well-known that there are very good book reviews and review essays on them, which you can find through jstor / your library's database. these can be invaluable both because your reading list would otherwise just mushroom out forever, and because a good review can help you decide whether you even need / want to sit down with the book itself in the first place. literally zero shame in reading an academic text secondhand via reviews.

This might be too broad of a question and sorry if it is (also sorry if it's been asked before?), but I wanted to ask if there are any particular books you may recommend to someone learning about psychology?
Also what did Rosmontis do if I may ask
Rosmontis: here.
Psychology: I personally recommend learning about second-order cybernetics, in which the observer is circularly and intimately involved with/connected to the observed. The observer is no longer neutral and detached, and plays an active role in system. This is key to Brofenbrennerâs Ecological Model. Basically, this stands conceptually opposite to the Lacanian take on Freudâs psychoanalysis, as Lacanian purists will insist you exist as an extraneous entity to the focal point being observed. You, as a psychologist, are still human and a mutable, mutation-inflicting aspect of any life you wander into. The psychologist as an outside-above observer is a flawed concept in my opinion.
All this prelude is to say: Read Ludwig von Bertalanffyâs âOrganismic Psychology and Systems Theoryâ, 1966, and get to know the General Systems Theory. One cannot work with one part of a system, micro or macro, if one hopes to truly help someone. What people often call âillnessâ tends to be symptoms of something else, and each person is a whole world.
Specifically about working with kids, I like Donald Winnicottâs works. âPlaying and Realityâ. Winnicott puts lots of emphasis on how creativity and play are incredibly good tools in understanding and communicating with babies and children, and this can and should be used alongside other techniques to create a platform of conversation, if needed, with older kids that for one reason or another struggle with conventional communication. Winnicott also proposes the âGood Enough Motherâ theory, which is to say, the best parent/caretaker is one who is good enough to healthily provide for the kid in all areas, and still messes up or lacks some skills overall to provide children a safe, controlled space of adversity; it is through this safe adversity that children learn to be self-sufficient by learning to make up for what the caretaker lacks or doesnât do perfectly. Overprotective parents, then, run counter to healthy development of the child, something that proves right more often than not.
Finally, Humberto Maturanaâs âThe Tree of Knowledge: The Biological Roots of Human Understandingâ. This is also about second-order cybernetics, more focused on how we learn, the science of knowing how we know. You know how someone telling you âtwo plus two is fourâ is meaningless, but if you add two and two, you get four, and now that has any meaning to you because you got to that realization through internal processes that organically lead to the answer? Ok, you know how it does jack shit to tell a depressed person to think happy thoughts, but if lived experience and rationale eventually leads you to âlife is worth livingâ, then that a life-changing effect on you? Well, itâs got to do with techniques on understanding this process and being an active agent in doing this with others.
I dislike psychoanalysis but it is worth reading Freudâs stuff, especially to understand where all of this comes from originally, and the technique isnât necessarily bad as much as it was a technique used in a place and time that is not where and when we currently live. Second-order cybernetics is something I especially like in psychology, because of how closely it relates to actual lived experience. A simple example is, if you throw a basketball to the hoop, you likely will miss, but your second attempt will be closer, and the third attempt, youâll likely nail it. This is because the previous attempts have given you input and information that you then incorporate to throw more accurately. This is first-order cybernetics as you are the sole, individual variable, but imagine you have a coach, and the coach isnât teaching you in a way that helps. The coach then changes their approach to suit your way of learning how to handle the element (ball), so the observed system (you, ball, act of throwing, hoop) is now changing, but so is the system observing entity (coach), as observer cannot be separate from observed system if aiming to meaningfully change it.
These should set you out to a good start, in my opinion.

astro observations pt. iv
⧠more saturn observations â§
⧠Whenever Saturn moves into Aries, I feel like thatâs going to be a âno bullshitâ season. Iâm not sure of the details but in theory, it sounds very blunt, upfront, and in your face. Whatever this karma is, you canât ignore it.
⧠If the writers currently donât get their well-deserved justice during this Saturn transit (which the more I think about would be very weird if they didnât), I think the dust will finally settleâend-all-be-allâ during the Gemini Saturn transit since Gemini rules over writing.
⧠Speaking of Gemini Saturn, I feel like the internet for politicians in the states is like the Wild West. I fully believe they have no clue what theyâre doing. If they do lay down some form of structure (maybe restrictions but Iâm not sure) during the Gemini Saturn transit would make sense.
PLEASE PLEASE PLEASE LOOK INTO SATURN TRANSITS IF YOU WANT TO MAKE CAREER MOVES!!
⧠As a student in computer science, I saw so many people getting jobs in tech left and right, getting certificates, and going to boot camps and everything (made me feel like shit but I digress). Also, we all saw the major influx of influencers too. I highly recommend looking into what sign Saturn is transiting to help you in your dream career. Itâs not like a boost overnight, but it is stable and if you work hard and stay disciplined, Saturn will reward you. The only warning is that you must do it the right way, I wouldnât consider any shortcuts or cheating. ⧠Though a lot of people got jobs in tech in the last few years when Saturn was in Aquarius, a lot of people (mainly project managers) lost their jobs when Saturn moved into Pisces. I think this because PMs were the easy way in, itâs basically like being a general manager in tech, no programming or code is really involved in their role.
Here are some benefitted professions for the upcoming transits. Note: If something doesnât align right now or doesnât at all, these transits arenât end-all-be-all! There are so many transits happening all the time that can be beneficial as well.
⧠Saturn in Pisces (March 2, 2023 - February 13, 2026) : for my creatives (especially my singers, musicians, actors, photographers, and visual artists), spiritual workers, mental health workers, etc. ⧠Saturn in Aries (February 14, 2026 - April 12, 2028) : for my entrepreneurs, models, athletes, trainers, any profession that requires physical activity and/or competition and challenges, etc. ⧠Saturn in Taurus (April 13, 2028 - May 30, 2030) : for my bakers, cooks, chefs, designers of all kinds, fashionistas, beauticians, and anything to do with beautifying, etc. ⧠Saturn in Gemini (June 1, 2030 - July 13, 2032) : for my bloggers, writers, teachers, journalists, anything to do with communication, media, language(s), etc.
thatâs all for now. see you later!

Anyone is welcome to interact with our posts in a respectful manner! However, we recognize that we cannot control who sees our posts (and how they respond). Still, we hope that our boundaries will be respected.
Please do not reach out to us if you are any of the following:
Support bigotry of any kind (racism, homophobia, transphobia, ableism, antisemitism, etc.)
Believe in cringe culture and online bullying (different from criticism, which is productive; bullying is only harmful :()
Support the actions of the state of Israel against the Palestinian people (we stand for the establishment of a free Palestinian state)
Trump supporters, right-wing, etc.
Are purely here to argue/change any of our beliefs; this is not the space for that! We appreciate criticism, but we would like for it to be done in a manner that is meant to help us grow and learn as people rather than for it to be delivered in a manner meant to demotivate us/reduce our self-esteem.
Are a pro-shipper; we won't send hate, but please do not contact us directly or follow our page!
AI âartistsâ
If you fall under these categories, we feel comfortable if you interact with our posts as long as itâs kept to likes or silent reblogs! Again, this is just a request from an internet stranger, but know that we would appreciate having our boundaries respected to ensure a comfortable time on the internet.
Additionally, if you fall under these categories and we interact with one of your posts, we ask that you either ignore us or reach out to us to let us know which post it is that we interacted with! Weâd be happy to delete. The same goes for if we fall under your DNI list; we ask to either be ignored or informed of our presence, so that we can delete whatever interaction we gave! We try to keep track of peopleâs DNI lists to see who would be comfortable with direct interaction (such as comments or asks) from us, but we ask that you understand that we might accidentally miss that DNI criteria or forget to check!
We won't talk much about syscourse on here. Syscourse-focused blogs are welcomed here, but we might not interact all the time with those kinds of posts if we follow back.
Our syscourse stance is complicated! We go by the information that childhood trauma is necessary to form systems in the medical sense. Dissociative disorders are fundamentally descriptors a specific criteria of symptoms. As for plurality outside of dissociative disorders (such as feeling âbornâ as multiple people, feeling that one âbecameâ plural over time, etc), it is not our place to deny those experiences. However, we believe that plurals whose parts originate from non-trauma related sources should use different entirely language to describe what they are going through.
Ultimately, discussion about the nuances of plurality/systemhood are bound to be tough, which in itself is proof that dissociative disorders are inherently linked to trauma. We arenât here to argue with others or prove a point; rather, just to hang out and talk about things that interest us. :]

mcl characters and uni courses or careers that i think they fit in
finals are kicking my ass sorry about dissapearing yall,,, but since i've spent sm time in campus these past few weeks this seemed fitting
i'll be back by the end of january, if i survive exams xx
kentin: vet studies or physiotherapy (iwaizumi hajime, 27)
nathaniel: i'm between med school at the beggining of the game but also a double degree in criminology and psychology for his detective-novella-loving side
castiel: starts off in some kind of sound engineering course but wouldn't mind music theory or smth along those lines (he'd eventually drop out to create a band anyway)
armin: game tech design, cs, some kind of cs engineering idk i'm not into techy stuff (sorry ;;) maybe cybersecurity stuff
alexy: he enjoys music and fashion but i see him going into a career in psychology or maybe even as a social worker working on cases of children and adoption
lysander: lowkey ornithology LMAO all jokes,,, he's the type to go into latin studies with ancient history and a sprinkle of literature studies all together and then become an author in the future (maybe acts as a ghost writer for castiel and other groups as a side thing)
kim: is it insane to say some masters in primary education or pedagogy?? i feel that she kinda becomes more serious about studies by the end of the game and she realises that all she needed was a better school system to believe in her
in anyway she opens up a gym and creates a special area all for classes with children where they can 'blow off steam'
violette: gets a full ride scholarship to many distinguished fine arts courses but it ends up being her making her teachers realise that they are learning more from her than anything else - also opens up a 'common space' for artists of all ages and backgrounds to have access to all sorts of art materials as a non profit project but makes a living out of commissions, expo's and teaching at her local community college
iris: i see her going into the tourism sector?? like - gets a quick professional formative course in hospitality, tourism and administration and leaves as soon as she can to travel around the world and adopt the odd job wherever she lands, she was never good at studies but she's known for being a very trustworthy tourist guide and vacation planner because she knows so damn much about all the places that she's worked in
melody: something in biological sciences is what i envision (idc if she works with zaidi in UL this game is MY CANON now)
priya: no doubt law studies she was made for it
peggy: again, obvious choice. journalism and something in social media maybe
rosa: helps out leigh with his shop for a short while but opens up her own fashion store and works as a fashion consultant for various clients
li: something business-econ related, idk
charlotte: also a business girlie but maybe with some studies in finance

Queer autonomous zones and participatory publics
Bobby Noble points to âthe simultaneity of the relations between gendered embodi- ment, sex play, and racialization inside homonormative communities, neighbour- hoods and venues for cultural productionâ (Noble, 2009). Similar critiques of the queer community have been taken up by Gay Shame anarchist activists organizing in the late 1990s. In Thatâs Revolting! Matt/Mattilda Bernstein Sycamore docu- ments their personal experience in Gay Shame collectives in San Francisco and New York City. âGay Shame emerged to create a radical alternative to the confor- mity of gay neighbourhoods, bars, and institutions â most clearly symbolized by Gay Prideâ (Sycamore, 2004: 238). Gay Shame is âmostly anarchist leaningâ (2004: 239), and organizes gatherings, events and direct action protests against capitalism and intersecting oppressions. A San Francisco flyer asks, âAre you choking on the vomit of consumerist âgay prideâ?â (2004: 239). Another poster entitled âGay pride, my ass: Itâs all about gay shameâ (2004: 240) announces an âautonomous spaceâ (2004: 240) outdoors on Tire Beach with performances, art-making, bands, instal- lations, DJs, food, kidspace, and âpolitics and playâ (2004: 240). The event hosted âspeakers on issues including San Francisco gentrification and the US colonization of the Puerto Rican island of Vieques, as well as prison, youth, and trans activismâ (2004: 241). The range of issues and events in the âautonomous spaceâ point to a very different kind of sprawling, engaged public than Berlant and Warnerâs indoor, circumscribed, queer counterpublic. âWe encouraged people to participate in cre- ating their own radical queer space, and people argued about political issues, painted, poured concrete and made a mosaic, dyed hair, and mudwrestled nakedâ (Sycamore, 2004: 241). Participation is a key element in the formation of a âQueer autonomous spaceâ (2004: 237) or zone, as are multiplicities of political focus (Puerto Rico, kids, youth, prisons, trans people, art production, gentrifica- tion and so on) and an over-arching anti-capitalist practice that includes free entrance, barter and trade, dressing to âragged excessâ (2004: 240), and the provi- sion of âfree food, T-shirts and various other giftsâ (2004: 241).
Queer autonomous zones thus are open-ended spaces in which participation of all comers is encouraged through a direct (rather than liberal) democracy model. They are facilitated via engagement with a multiplicity of intersectional anti- oppression politics. Interactions in queer autonomous spaces develop sustainable social relations and value-practices, based on mutual respect, consent, sexual lib- eration, and non-normativity, in which people engage in open-ended processes of developing alternative ways of being, feeling, thinking, engaging, acting and becoming-liberated. The question is â whatâs next? How do we continue to expand our movements and theorizing to extend the becoming-liberated of queer?

[1] Following Vadeâs important article (2005) advocating the âGender Galaxyâ which reveals the falsity of the gender/sex divide and the negative legal impact of this distinction on trans people, I am using the term âgenderâ to be comprehensive.
[2] In the USA this is particularly true. In Canada same-sex marriage and human rights are protected by the Charter of Rights and Freedoms, and immigration processes are begin- ning to include same-sex partners in sponsorship claims, as well as considering persecution for sexuality as a basis for refugee claims. These processes however remain heteronorma- tive. Iâd like to thank Melissa White for sharing her insights and research on this issue.

Podcast episode discussing DS9 "Past Tense" & "Far Beyond the Stars"!
My friend Laura invited me onto their podcast to unpack Deep Space Nine episodes 3x11 & 12: "Past Tense" and 6x13: "Far Beyond the Stars," using them for a broader discussion on the role of science fiction in dreaming better futures into reality.
In our conversation, we:
compare the 2024 of "Past Tense" to our 2024
share our theories about historical events that may have inspired both episodes, as well as their relationship to other works of speculative/science fiction
point out and offer revisions for parts of "Past Tense" that somewhat undercut the story's intended messages about the evils of capitalism, ableism, police / military violence, and anti-homeless laws
gush about the artistry of the filming and acting in "Far Beyond" (Avery Brooks monologues my beloved)
and more â with a dash of humor as we go!
Give "Sanctified Imagination Far Beyond the Stars" a listen wherever you get podcasts â or read along with the transcript!
(CW: Christianity) â please do go in forewarned that Laura's Autistic Liberation Theology podcast centers around reinterpreting the Bible from a trans & disabled lens. If you skip to 44 minutes in you'll miss most of the religious commentary, except for when it makes sense to bring it up re: Joseph Sisko's 1950s incarnation as a street preacher.
If you are interested the full episode, some of the places we go in our winding conversation are:
Womanist midrash & sanctified imagination, which enact this call to imagine possibilities for the oppressed â to "make a way out of no way"
How Jesus's use of parables to teach about his envisioned "Kingdom of God" âwhere there's access for all, oppressors reformed and oppressed liberated, all needs met and all gifts celebrated â invites people to engage their sanctified imaginations to join in the work for a more just world, here and now
AutScape's & Crip Campâs modeled possibilities for a fully accessible, disability-centered world
various directors / show writers who, through writing, discovered something new about themselves (think the Wachowski sisters & The Matrix, Dan Harmon and Community)
If you give it a listen (or read), I'd love to hear what you think! Did you connect with the concept of imagining better futures into reality? Any other Star Trek episodes you think encapsulate that well?
____
Transcript of the above audio clip:
Avery: I definitely think the writers of this episode were thinking about how When Deep Space Nine was coming out, people's response to seeing Sisko was, Yeah, is, you can't have a black space captain. A black man can't be the hero of Star Trek!
Which just shows, like, for the viewers, like, Yeah, we've come a long ways here in the 90s. But we still think it's ridiculous to imagine a black space captain and it's only just becoming possible now.
Laura: yeah the um, , editor of the magazine says "put it in a drawer for like a couple of decades and might be--" it's like, yeah, that's
Avery: Yeah.
Laura: inside joke.
Avery: At the end, when, um, Benny Russell breaks down after being fired and everything, the street preacher comes back and, Benny says, "Tell me, please, who am I?"
Don't you know?" "Tell me." "You're the dreamer and the dream."
Laura: ah, this is so amazing.
Avery: And, like, yeah, that fits on so many different layers with, uh, Benny Russell is dreaming Sisko and dreaming Deep Space nine, and also Sisko is dreaming him, and also breaking the fourth wall,
Laura: yeah, because they're, neither of them are real, they're both fiction and yet they're, yeah. real.
Avery: Yeah. Yeah. Breaking the fourth wall, the writers and Avery Brooks are the dreamers, and the dream. This is, this is what, people have been dreaming of, this even the possibility of this. And they're making it true.
Laura: and at the end, you see him looking out the window and seeing Benny Russell in the reflection of the glass and
Avery: it's such a good shot. It's so good. It like gives me chills
Laura: you Have to cast something into the space you're not there yet to-- that becomes you.
Avery: Yeah. dream yourself into being.
#star trek#ds9 past tense#far beyond the stars#ds9#deep space nine#We intended for the ep to come out the first week of September in honor of the 2024 Bell Riots predicted in âPast Tenseâ#buuuut we both run on crip time soooo it's a little late. alas! i still hope folks enjoy our conversation#And hey if you wanna listen to it during those riotous first days of September#just hop on your transporter in your chroniton-particle-logged ship during a temporal surge#and it should beam you right back to when you want to be :P

Astronomers deal a blow to theory that Venus once had liquid water on its surface
A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbor was once much more like Earth than it is today.
The researchers, from the University of Cambridge, studied the chemical composition of the Venusian atmosphere and inferred that its interior is too dry today for there ever to have been enough water for oceans to exist at its surface. Instead, the planet has likely been a scorching, inhospitable world for its entire history.
The results, reported in the journal Nature Astronomy, have implications for understanding Earth's uniqueness, and for the search for life on planets outside our solar system. While many exoplanets are Venus-like, the study suggests that astronomers should narrow their focus to exoplanets which are more like Earth.
From a distance, Venus and Earth look like siblings: it is almost identical in size and is a rocky planet like Earth. But up close, Venus is more like an evil twin: it is covered with thick clouds of sulfuric acid, and its surface has a mean temperature close to 500°C.
Despite these extreme conditions, for decades, astronomers have been investigating whether Venus once had liquid oceans capable of supporting life, or whether some mysterious form of 'aerial' life exists in its thick clouds now.
"We won't know for sure whether Venus can or did support life until we send probes at the end of this decade," said first author Tereza Constantinou, a Ph.D. student at Cambridge's Institute of Astronomy. "But given it likely never had oceans, it is hard to imagine Venus ever having supported Earth-like life, which requires liquid water."
When searching for life elsewhere in our galaxy, astronomers focus on planets orbiting their host stars in the habitable zone, where temperatures are such that liquid water can exist on the planet's surface. Venus provides a powerful limit on where this habitable zone lies around a star.
"Even though it's the closest planet to us, Venus is important for exoplanet science, because it gives us a unique opportunity to explore a planet that evolved very differently to ours, right at the edge of the habitable zone," said Constantinou.
There are two primary theories on how conditions on Venus may have evolved since its formation 4.6 billion years ago. The first is that conditions on the surface of Venus were once temperate enough to support liquid water, but a runaway greenhouse effect caused by widespread volcanic activity caused the planet to get hotter and hotter.
The second theory is that Venus was born hot, and liquid water has never been able to condense at the surface.
"Both of those theories are based on climate models, but we wanted to take a different approach based on observations of Venus' current atmospheric chemistry," said Constantinou.
"To keep the Venusian atmosphere stable, then any chemicals being removed from the atmosphere should also be getting restored to it, since the planet's interior and exterior are in constant chemical communication with one another."
The researchers calculated the present destruction rate of water, carbon dioxide and carbonyl sulfide molecules in Venus' atmosphere, which must be restored by volcanic gases to keep the atmosphere stable.
Volcanism, through its supply of gases to the atmosphere, provides a window into the interior of rocky planets like Venus. As magma rises from the mantle to the surface, it releases gases from the deeper portions of the planet.
On Earth, volcanic eruptions are mostly steam, due to our planet's water-rich interior. But, based on the composition of the volcanic gases necessary to sustain the Venusian atmosphere, the researchers found that volcanic gases on Venus are at most six percent water. These dry eruptions suggest that Venus's interior, the source of the magma that releases volcanic gases, is also dehydrated.
At the end of this decade, NASA's DAVINCI mission will be able to test and confirm whether Venus has always been a dry, inhospitable planet, with a series of flybys and a probe sent to the surface. The results could help astronomers narrow their focus when searching for planets that can support life in orbit around other stars in the galaxy.
"If Venus was habitable in the past, it would mean other planets we have already found might also be habitable," said Constantinou. "Instruments like the James Webb Space Telescope are best at studying the atmospheres of planets close to their host star, like Venus. But if Venus was never habitable, then it makes Venus-like planets elsewhere less likely candidates for habitable conditions or life.
"We would have loved to find that Venus was once a planet much closer to our own, so it's kind of sad in a way to find out that it wasn't, but ultimately it's more useful to focus the search on planets that are mostly likely to be able to support lifeâat least life as we know it."

came across a post by astriiformes (astriiformes(.)tumblr(.)com/post/742882591316803584/hi-i-just-learned-about-the-scientific-revolution) that objected to Kuhn's theory of scientific revolution on the basis that they felt it leant in to the "great men of history" model. I never understood it this way, but I haven't read the bookâI thought it was more about explaining the lag between accumulation of evidence that goes against the current paradigm and full paradigm shift. thoughts?
kuhn's model of 'paradigm shifts' is certainly prone to inviting 'great man' explanations of scientific developments. i would even go further, and say that this is due to a fundamental issue in kuhn's methodology, which is a tendency toward idealist analysis that fails to consider material and sociological factors. astriiformes points out that these days, kuhn is more popular with economists and political scientists than with practicing historians of science; this is true and not a coincidence.
astriiformes also walks through a valuable line of objection to kuhn, which is that the scientists we tend to credit with having made singlehanded discoveries were in fact usually embedded in vibrant scientific communities and ongoing debates, and were influenced by their contemporaries as well as their intellectual forebears. this is all true. another critical angle to interrogate here, and one where the Great Man often pops up again, is in kuhn's version of how scientific ideas are actually adopted: in other words, how he considers a 'paradigm shift' to actually occur, even once we assume the idea in question has already been formulated. let me chuck a few case studies at you because it's easier than talking in generalities.
for much of the 20th century, the 'standard story' of galileo's trial and imprisonment was that, having dared to become a lone voice defending heliocentrism, he was made a martyr to truth by the church, which was threatened on theological grounds. however, in the last several decades historians of science have studied much more seriously the patronage networks of renaissance italy: the structure of funding and epistemological authority whereby a scientist like galileo secured money, university or court positions, and respect by gaining mutually beneficial relationships with various nobles and other wealthy people. galileo had defended heliocentrism prior to the church's crackdown on him and his work; so had certain other astronomers. although it's true the church had theological objections to what galileo was saying, they were pretty much forced to tolerate him as long as he had sufficient patronage protection: wealthy, powerful people using their social clout to defend him. but this fragile truce was shattered when galileo lost the support of certain of his patrons, particularly some jesuits, in the early 1630s and thus became a much more vulnerable target of church censorship. it was only at this point that the church placed him on trial and then eventually under house arrest, and forced to recant.
evolutionary ('transmutationist') ideas were not new by the time darwin published the 'origin' in 1859. most french biologists at this time supported some variant of transmutationist ideas, and even in britain, transmutation of species had long been hotly discussed in the edinburgh medical schools in particular. the challenge for the wealthier london gentleman-naturalist set was that transmutationism had previously been associated with radical, materialist, atheist politics (this was precisely what appealed for many in edinburgh), and although evolutionary ideas had circulated in the wider reading public, these had typically been carefully framed to remain compatible with dominant anglican morals (eg, robert chambers's 'vestiges' of 1844). so, why were charles darwin's ideas accepted where others had been suppressed, ignored, or mired in controversy? a few reasons: again, a strong patronage network and powerful social connections (familial and personal); also, darwin very consciously avoided talking about human descent in 1859 (he did not do so until 1871's 'descent of man', which remains less widely read to this day) and avoided open avowal of materialism or atheism in his published works. furthermore, despite what lay histories may suggest nowadays, darwin's ideas were not embraced immediately or uncritically. they circulated piecemeal, with the help of 'popularisers' like haeckel and th huxley whose teachings often varied pretty widely from what darwin actually said or thought. and, prior to the 'modern synthesis' unifying 'darwinian' evolution with mendelian genetics, one of the most common objections to darwin's ideas was that he had provided proof of no actual mechanism of heredity, which resulted in a retrospectively fascinating period of anglo and french scientific writing between about 1890â1940 that often circulated the claim that darwin had been proven embarrassingly wrong, and it was jean-baptiste lamarck who had instead been vindicated by the biologists of the middle victorian era.
louis pasteur has historically been credited with ushering out the last vestiges of 'miasmatic' and 'environmentalist' theories of disease in france, and replacing them with good solid bacteriology. this is simply a misrepresentation of scientific beliefs among the lay public, technical experts like public health officials, and even working scientists under the third republic. because hygienists and sanitation engineers had spent much of the 19th century creating professional prestige for themselves as managers of the insalubrious environmental factors plaguing particularly the urban poor, you can imagine they were not generally thrilled at the proposition that someone had actually confirmed the existence of a microscopic 'germ' of disease, a foreign entity that could be studied and eradicated by a laboratory scientist with entirely different credentials and training. so, as it became clear that the actual eradication part was still a challenge, and that disease risk did not strike all people or demographics equally, french hygienists by and large simply altered their rhetoric a little. yes, germs existedâin fact, clearly, these were what the hygienists had been protecting people from all along by encouraging cleaner air, open spaces, gymnastic exercise, &c! this is the root of what's now known in the historical literature as the 'sanitary-bacteriological synthesis'ânot an overturning of an old 'environmentalist' paradigm for a modern bacteriological one, but rather a melding of the two that enfolded pasteur's and koch's discoveries whilst still shoring up the professional authority of the hygienists and sanitarians.
in all three of these cases you can see how a strictly kuhnian analysis of 'paradigm shifts' over-emphasises the role of the Great Man (here in his guise as Genius Scientist) because it overlooks critical factors like the social and professional networks that actually allow knowledge to spread, and the professional and pecuniary interests that motivate people, consciously or not, when they evaluate new theories or ideas. galileo did not suffer from 'failing' to spark a paradigm shift, any more than darwin singlehandedly succeeded; their ideas circulated, mutated, and provoked on the strength of relationships as much as pure cerebral Theory. pasteur's claims likely could not have achieved the renown they did, had they not been helped along by hygienists who saw in them a change to re-form and reinforce their own profession and authority.
kuhn's work was an important departure from earlier positivist, largely teleological histories of science: the 'paradigm shift' allowed people to talk about massive and notable changes in science without having to accede to a model that assumed constant, linear progress. in this sense, much of today's history of science (still a comparatively immature and evolving field!) belongs to a citational lineage that will eventually pop up with kuhn's name. but, methodologically, kuhn leaves a lot to be desired, because his analysis is generally founded in an intellectual history that configures Science as a world of disembodied ideas unburdened by social, material, and economic considerations and practices.

I'M LAUGHING
I WENT ON PLURALPEDIA TO YOINK A SYSTEM SYMBOL N SAW A PAGE ON STRUCTURAL DISSOCIATION N THEY'RE TRYING TO DISCREDIT A LITERAL SCIENTIFIC THEORY BECAUSE IT'S NOT PRO ENDO N USES PARTS LANGUAGE???????
so y'all can see what I'm seeing here
I'm just gonna edit this to add on
it's wild how (most) endos will say that they're not dissociative but then insert themselves into conversations and medical research about an experience that they're saying they're so different from, they will get so mad at science because their pseudoscientific community doesn't fit into actual science
also calling using parts language dehumanizing in this context is seriously something, part is the best word to use in this context because it's also talking about other disorders that cause heavier dissociation, using language like alters won't apply to PTSD, cPTSD or BPD even if it applies to OSDDID but parts applies to all of those, it's literally just using accurate language

WHAT IS QUARK MATTER??
Blog#363
Wednesday, January 3rd, 2024.
Welcome back,
Deep within the atoms that make up our bodies and even within the protons and neutrons that make up atomic nuclei, are tiny particles called quarks
Quarks are the ultimate building blocks of visible matter in the universe.
If we could zoom in on an atom in your body, we would see that it consists of electrons swarming in orbits around a nucleus of protons and neutrons.
And if we could zoom in on one of those protons or neutrons, we'd find that they themselves are made up of a trio of particles that are so small that they have almost no size at all, and are little more than points. These point-like particles are the quarks.
Quarks are elementary particles. Like the electron, they are not made up of any other particles. You could say that they are on the ground floor of the Standard Model of particle physics.
The existence of quarks was first theorized in 1964 in the work of two physicists, Murray Gell-Mann and George Zweig, who were both at the California Institute of Technology (CalTech) but who came to the conclusion that quarks exist independently of one another. Contrary to how science is often portrayed in the media, Gell-Mann and Zweig's conclusions were not an "a-ha!" moment but were instead built on the back of many years of hard work and careful discoveries by the particle physics community.
By the 1950s, physicists were building up a library of known particles. It was a bit like botany, cataloging the various types and their properties, but what was missing was an underlying theory behind their existence. This theory ultimately became known as the Standard Model, but in order to get there several vital discoveries had to be made, including that of quarks.
Most puzzling was the existence of particles called hyperons, which were unstable and decayed very quickly, but not into the particles they were expected to decay into.
Gell-Mann realized that there must be an unknown quantum property at work, which he named "strangeness" because of the unexpectedness of it all.
Quantum numbers, like strangeness, charge and spin, have to be conserved. If a particle with a specific quantum number decays, then its by-products must add up to those quantum numbers that the decayed particle had. Moreover, the quantum numbers of a given particle have "degrees of freedom" â basically the range of values that these numbers can have.
These degrees of freedom are called multiplets, and the pattern in which these multiplets could be arranged between different particles led Gell-Mann and Zweig to believe that the particles and their multiplets could be explained if each particle was formed from two or three smaller particles.
Zweig called these tiny, elementary particles "aces", but the name didn't catch on.
Gell-Mann, who was ever one for cooky and memorable names, called them quarks, derived from a line in James Joyce's experimental novel, Finnegan's Wake: "Three quarks for Muster Mark!" In the novel, the quarks refer to the three children of the main character, Mr Mark.
These quarks were referred to as "up", "down" and "strange" quarks. The up and down doesn't really refer to anything, while the strange quark had a quantum number of strangeness of â1, hence why it is called "strange", whereas the up and down quarks have a strangeness of 0.
