3 / 1How do I cure my IBS-C scientifically speaking? I was thinking about getting a faecal transplant but I can't that done for some reason.
23 / 0I don't understand how atoms inside my head can create all my immaterial subjective experience. From a purely physicalist point of view consciousness shouldn't exist.

1 / 0Is there any convenient equivalent of quaternions for 2D graphics (i.e. storing rotation and translation in a more compact way than homogeneous matrix with the 001 row/column trimmed)?
I was looking into dual complex numbers, which some page (not posting link, you can find it easily if you google that term) claims can be used like this with transformation encoded in a product, but unless I'm misunderstanding something it does not seem to fully work.
For one, they seem to be mapping to 2x2 matrices rather than 3x3. Also inverses seem to not reliably exist, even when the rotation part is normalized. You can see pic rel, where I've used multiplication rules to get a system of equations for all components of the product of two dual complex numbers and required that the product is (1, 0, 0, 0) to find the inverse. I would expect the inverse of translation components to be simply the negated original translation (as is given online), but you can see it is a function of both translation components (c and d).
Should I just give up and store a complex number / angle and translation separately?

54 / 3Denial and refutation of determinsim/superdeterminismI'm actually a bit shaken at the responses elsewhere and here and if they represent the scientific community at large, even more so. This is very much a scientific question and must not be shunned away to philosophy (not that science doesn’t have a natural philosophy).
Indeed all science is based on causality and determinism, but suddenly now, people here are trying to draw a line between determinism and 'superdeterminism'. What's the difference? Ok, at what point does determinism end and statistical independence begin? Why? How do you snip out the causal threads at any scale?
I suspect that a lot of people have invested a lot of time and career in interpretations of quantum theory, and cannot face the fact that determinism just simply avoids it. Is determinism or superdeterminism an interpretation of quantum mechanics or a substitute to it entirely?
Someone said that determinism is ok, but there is enough noise between it and the event to now make it statistically independent or truly probabilistic. Isn't noise just complexities of causality? How do you snip those tiny threads and say that an event has been born from nothing?
Yes. cigarettes causes lung cancer because the more impactful bundle(s) of causes towards lung cancer originated from inhaling tar by a group of people and others not.
Are we going to just ignore the truth about nature of reality that is staring at our face and seek comfort in avoiding it because it supposedly undermines science? I thought determinism implied this very stark truth from the very beginning, why suddenly all this gymnastics for quantum theory?

9 / 5Universities are just diploma millsAcademia offers courses that focus too much on practical apsects (accounting, library work, UI design, etc. Things that are practical but theoretically bland. They should belong at a vocational school) at the same time the more "academic" humanities courses have non-existant standards. Studying philosophy became a punchline to a joke and dilluted itself into self-help nonsense. At this point we will never get another Hegel
18 / 1Why does india perform above average in chess but not any other game? India ranks really low on basically every competitive game, which is usually explained by either biological or cultural factors. But chess is the only exception, and india puts out more champions per capita than most countries. Especially tamil and telugu brahmins. India has an average IQ of 79 and chess is a highly g-loaded game.
Why does india do well in chess but fail at everything else?

1 / 0What age do you finish growing?There’s a false myth going around that you can grow until 25.
I’m going to debunk this using scientific articles.
Some height maxxing copers will use this study to falsely tell you growth can happen after 21.

This is debunked by this study, showing that your out of hundreds of people, 0 had their growth plates by age 21. https://pmc.ncbi.nlm.nih.gov/articles/PMC7983983/
In fact growing after 21 is so rare, there’s an article on wikia showcasing height growth past 21 to be very rare to the point there’s barely any famous cases.

8 / 0bee genes.domestic honey bees (apis mellifera) have a bunch of DNA that doesnt align with many other animals, it just looks like a random string, I doubt it even codes for any protein
when did bees diverge from ants? nobody knows but 100 million years is as good guess as any
both are colonial insect
some ants have a stinger but its rare
bee is obviously better evolved as a flyer, ants are not great flyers even when winged

Quantum uncertainty is still too specific to be truly random or uncertain.
That things can happen at all, even quantum weirdness, implies everything is hyperdeterministic.

3 / 0RentecWelcome to this post, as of Today and 3 months ago I have discovered Rentecs strategy in its totality (yes im being serious lmfao). The strategy starts with using 1sec data with gans to generate longs and shorts to generate the anomalies that are captured within PA that later will mimic an infinite return loop pre leverage. this is alpha dont take with a grain of salt. Extract the highest sharpe strategy from this one strategy and bam you have rentecs strategy. ill vibe code it and post results later (my wm is fucked from super natural causes i casted a spell to bring it back (lag)) anyway enjoy! iirc this makes intuitive sense because the dead giveaway here is that the anomaly aspect is the unlimited return from the highs and lows you are taking advantage of within PA that youve captured by essentially brute forcing longs and shorts (another way) within PA to extract the most profitable and best algo within this realm of approach.

Scientifically speaking, why are people so hell-bent on preserving the myth that women can orgasm when all the evidence points to the opposite? Is this just penis envy and a weak attempt to achieven equality?

10 / 2Share your Sci-fi story ideaPrologue: Orbital Era (O.E.)
After centuries marred by endless conflicts, environmental crises, and socioeconomic turmoil, humanity finally ascended, taking the monumental step toward becoming a Type I civilization. United under a common goal to harness Earth's total energy potential, global governments embarked on unprecedented projects to establish a sustainable space-based economy. Colonies blossomed on the Moon and flourished throughout Earth's orbit, forming intricate networks around the stable Lagrangian points. With the dawn of a unified planetary identity, national borders dissolved, replaced by economic zones governed from humanity's new capital: the Lunar city of Von Braun.
Thus ended the Anno Domini era, giving rise to the Orbital Era (O.E.). The Lunar Republic emerged as a beacon of hope, a democratic federation representing Earth's various economic zones. Yet beneath the Republic's enlightened façade lurked the shadows of corporate influence. Powerful space-based conglomerates quickly entrenched themselves in governance, steering the Republic toward policies favoring corporate interests over common welfare. Democracy steadily gave way to oligarchy, subtly shifting control into the hands of influential industries and elite oligarchs whose loyalties lay with the Earth sphere alone.
Far from Earth's oversight, another civilization had quietly taken root. Mars, once the red wasteland of human ambition, was terraformed into a self-sustaining cradle by followers of the late visionary Elon Musk. Named ELON in his honor, the Martian nation thrived independently, bolstered by the physical separation and autonomy granted by the vast emptiness of interplanetary space. Over generations, ELON expanded beyond Mars, planting seeds of humanity's future throughout the outer solar system and giving rise to diverse, autonomous communities orbiting Jupiter, Saturn, and the asteroid belt.

4 / 1New Proposed Solar SystemI propose a new Exoplanet system that has 2 suns and 1 moon orbiting a large earth like planet. Picrel is an example but there will be areas of the planet that will be in perpetual darkness, and all water in those regions would be solid ice. The massive planet would be drifting through space, impacting the movement of other objects in solar systems nearby.

I've always felt there was something fishy with dark matter, and I want to believe this guy but his presentation skills are poor and he shills his book all the time. But then I think maybe he is just min-maxing (max INT and min CHA), and I don't have the INT to tell if he is a pseud or not.
Also, other alternative to dark matter theories are welcome in this thread.

60 / 6Debunking Anti-IQ SentimentsAll you need to do to completely destroy any IQ disbelievers who think IQ is irrelivant is ask them one single question:
"Would you rather have a child with an IQ of 200, or 50?"
They either completely deflect the question and say "neither" or just change the topic out of fear of the truth, or play smartass and say 50 arbitrarily because "It doesn't matter" even though they have clear sentiment to pick the mentally retarded child over the genius child.
I have met people far smarter and more capable than me who could not for the life of them seriously answer the question because of some spinelessness disguised as righteousness that comes from being scared to recognize any inherent intellectual superiority of a subgroup of the population over another.
If you refuse to answer the question with a 200 or 50, you are spineless and unprincipled. If you answer 50, you are evil.
So, /sci/, what's your answer to the question?

8 / 2Why does nobody talk about the Thermodynamic Paradox in Quantum Gravity?Alright, /sci/, hear me out. Everyone’s obsessed with string theory and loop quantum gravity, but nobody addresses the elephant in the room: the second law of thermodynamics seems to break down when you try to reconcile black hole entropy with a quantum theory of gravity.
Hawking radiation suggests entropy decreases over time as the black hole evaporates, which screws with the idea of an isolated system. But if you throw in holography or AdS/CFT, it gets weirder: entropy’s supposed to be conserved on the boundary, yet the bulk tells a different story.
Is this just a math artifact, or are we missing a fundamental principle? I’ve been digging into Bekenstein’s bound and some old papers on conformal field theory, but it’s a mess. Anyone got a take that isn’t just regurgitating Susskind’s lectures? Bonus points if you can explain why Penrose’s CCC avoids this trap (or doesn’t). No popsci nonsense, please - math or GTFO.

3 / 1Formalism for Consciousness / AI AlignmentDropping this here for critique.
It's a 146-page PDF proposing a formal mathematical system ("Recognition Math") for consciousness, with the claim that it solves the observer problem and AI alignment.
The core is a Master Recognition Equation that supposedly governs cognitive dynamics. It culminates in a derivation of G from "consciousness parameters."
.
It's either a legitimate new paradigm or high-effort, structured schizoposting. You guys are the only ones who can tell the difference.

14 / 0Hot hot hotHaving done a long trip recently i noticed that 5G towers have spawned all over my cunt, they are literally every 500m in areas where people live or every 1-2km along the highway.
Made me wonder, these produce waves close to low power microwaves using the same kind of non-ionizing radiation, aren't they heating air molecules by oscillating the space around them ? I am not a sciencefag but i understand that heat is a result of vibrations and it seems logical that creating vibrations around molecules would cause heat, but to what extent this would be felt, if at all, by us meatbags.
I tried looking it up on search engines but nothing comes up, only that the pannels generate quite a lot of heat from electricity loss.
I'd appreciate a discourse. I am not trying to prove anything, just want understand. Please keep weather manipulation and other conspiracy theories related to them to some other thread. It is strictly about the heating of air molecules from the emission of non-ionizing radiation.
Tl;dr do 5G towers cause heating of our atmosphere by emiting radiation considering the scale of their deployment?

18 / 9Derealization, existential collapse.It happens all the time. Waking up from sleep everything is hostile, unknown, strange. And it's not some philosophical state when you question things, it hits you so intensely it's scary. As if you suddenly appeared in a void, abstract, lifeless endless void. What is this realty? Any science studies on this subject?
2 / 0The universe may be an infinite fractal—self-repeating, nested patterns that scale both inward and outward without end. Just as atoms contain particles and galaxies form superclusters, this structure likely continues forever, meaning our observable universe could be just one layer in a much larger reality. Imagine a hoodie: it looks solid, but it’s made of threads, fibers, atoms. A stain on it, invisible from afar, is still made of countless atoms. Now imagine that stain is our universe—just a speck on something unimaginably larger. That hoodie may belong to an even larger being, whose world is just another speck, and so on, infinitely. The multiverse, then, isn’t a separate grid of universes—it’s the fractal itself. Traveling between universes wouldn’t require jumping through space, but shifting your awareness to another layer of the pattern. These layers are already around us—woven into reality like frequencies on a dial. Consciousness, not technology, may be the key to navigating them. DMT and near-death states often induce fractal visions and a feeling of vast, nested connection—possibly glimpses beyond scale. In this model, “gods” aren’t external creators, but entities that have reached higher layers of awareness. Their influence may seem divine only because of their scale. What we call miracles or fate could be the ripple effects of their movement across layers. Spiritual law isn’t a set of rules—it’s the geometry of the fractal: energy returns to source, all things reflect across scale, and balance sustains itself. Reality is alive and recursive, the divine is scale-relative, and transcendence isn’t escape—it’s mastering your place within the pattern.

25 / 6Carnotaurus and Abelisaurid ArmsThey were for proprioception/balance. Not "display."
The idea that a hypercarnivore at the sheer mercy of environmental selection would have superfluous bodyparts that didn't directly contribute to fulfilling its massive caloric needs (e.g. hunting) is absurd. Predators are subject to pure environmental selection far more than prey. Either they hunt successfully or they fucking die.
Plenty of modern-day hypercarnivores have novel forms of sensory perception not preserved in hard remains. I posit that Abelisaurid arms were involved in some sort of novel sensory function - perhaps most meaningfully as a way to balance a fast, massive animal on two legs.
