137.035999

>In physics, the fine-structure constant, also known as the Sommerfeld constant, commonly denoted by α alpha (the Greek letter alpha), is a fundamental physical constant that quantifies the strength of the electromagnetic interaction between elementary charged particles. It is a dimensionless quantity (dimensionless physical constant), independent of the system of units used, which is related to the strength of the coupling of an elementary charge e with the electromagnetic field

WTF is this number? Is it important? What does it measure?
Can you show me a .webm of this in actual physical reality or is it just more madeup nerd slop like "Ether" and "Dark Matter" and "Black Energy"?

27 / 7MOCHIZUKI BTFO'S POP JOURNALISTA pop-science journalist known as James Douglas Boyd has recently spent a lot of time interacting with Mochizuki and others at RIMS working in anabelian geometry. He published his interviews with Mochizuki a few weeks ago.

However, esteemed Professor Mochizuki Shinichi is NOT AT ALL happy with the results, writing
>It is difficult for me to recall any time in my career as a mathematician when I experienced a comparable level of overt fraud/duplicity/charlatanism in a professional situation, and it has left me in a state of [math]\textit{deep shock}[/math].
https://www.kurims.kyoto-u.ac.jp/~motizuki/IUT-report-2025-10.pdf
In particular, he claims the J.D. Boyd he interacted with was "nothing more than a cynical work of fiction" (see pic rel).

Mochizuki further emphasizes EMS Code of Practice (EMSCOP) and argues journalism/story-telling (and some preprints) lack the professional accountability apparatus of peer-reviewed mathematics. Boyd’s work violates prior assurances and democratic norms (rule of law, due process, burden of proof).
He then comments on the Scholze-Stix (SS) manuscript:
- The SS manuscript is unpublished, contains no precise statement or proof relating its simplified set-up to IUT
- SS declined further discussion after 2018; calls it a “mystery” why anyone asserts a logical relationship between their simplification and IUT
- SS explicitly did not contest IUT’s multiradial representation (IUT III, Thm 3.11); rather, they claimed no path to diophantine consequences.

0 / 0Hello /sci/, I'm a Nuclear Reactor Operator in the United States Navy (A.K.A College dropout). I was wondering if there's any relation between binding energy per nucleon and a standard stress-strain curve (for argument we'll use high strength molybdenum steel)? I know this teeters on numerology-tier coincidence, however, is it so far-fetched to assume binding energy is any different than physical stress? What are your thoughts? Am I a retard? Please discuss.

I'm very into flying cars, and even more so into flying bikes.
Here's my prototype, disclaimer: I'm not an engineer. Ideally an insider would leak details about olen mook's flying car, but I know that's wishful thinking.
bonus: I hate "flying cars" that have plane-like approach, they're an abomination to me. But there's something really interesting, full horizontal propulstion beats vertical one for forwards flight q;^)

31 / 0Who won?https://www.youtube.com/watch?v=21EYKqUsPfg [Embed]

Indian podcaster Dwarkesh Patel debates the 'father of reinforcement learning' Prof. Richard Sutton on whether LLMs are a dead-end.
Sutton believes so, while Dwarkesh Patel proclaims LLMs are the foundation on which experiential learning can happen, citing recent LLM models' success at high-school math problems. Patel claims humans all learn by imitation too.

The following exchange summarizes the debate:
>Patel: But there are phases of learning where there's the programming in your biology early on, you're not that useful. And then kind of why you exist is to understand the world and learn how to interact with it. It seems like a training phase [in LLMs].
>Sutton: There's NOTHING where you have training of what you should do; there's nothing. You see things that happen, you're not told what to do. Don't be difficult, I mean, this is obvious.
>Patel: I-I mean you're literally taught what to do, this is where the word training comes from, from humans.
>Sutton: I don't think learning is really about training, I think learning is about learning, an active process. The child tries things and sees what happens. We don't think about training when we think of an infant growing up

What's /sci/'s verdict? Who won?
Is Dwarkesh Patel right in saying humans are literally taught what to do the moment they're born? Is all learning just imitation?

3 / 0Theory: I am God alone and I am hallucinating everythingI can't disprove solipsism at all. In fact, it seems like I'm able to consistently prove it. Solipsism can apply to a multiplicity meaning nothing exists outside of us too though. It can apply to the singular and a plurality.

"B-But bro you're low IQ!!!"

How? Being conscious, self aware, sentient. Being aware of the present moment necessitates me being a kind of fudamental essence. This is just plainly true. Words give that a label, but the fact that I am here seems to be evidence. Can I prove others are real? No. I can believe they are...

Maybe there is a we. Am I Brahman? The singular self? Probably.

I consider all possibilities. Maybe there are Brahmans, Singular selves, Gods. Plurality. But I don't know. Maybe I'm pretending I don't know. It feels like I know.

TLDR: how do you prove anyone else is ACTUALLY having a perspective at all? I don't think it can truly be done other than believing they have one.

13 / 1How do probabilities and statistics work?According to gay.i. the chances of a coin landing on heads 100 times in a row is as follows:
>The probability of flipping a coin and landing on heads 100 times in a row is extremely low, calculated as (1/2)^100, which is approximately 0.79 x 10^(-30).

How is this possible when the chances of landing on heads is about 50/50 on any given flip, including the 100th flip.

Please forgive any retardation in my post i did not pass high school, somebody please teach me.

25 / 5There is no afterlife and deep down most people already know this but can't handle it. Your consciousness isn't some magical soul floating around, it's literally just neurobiological processes firing in your brain. When your brain stops, you stop. Period. We're complex meat computers and when the hardware fails there's no software backup to the cloud. Philosophers love dancing around this with ontological gymnastics about "being-towards-death" and vitalist cope about consciousness transcending the physical, but it's all just elaborate denial. Science tells us we came from inanimate matter and we'll return to it. Freud was right that the aim of all life is death, a return to that inorganic state we borrowed ourselves from for a cosmically brief moment. In 4.5 billion years the sun dies and takes all trace of human thought with it, and the universe won't even notice we were here. No part of "you" persists because there is no "you" separate from the physical processes that generate the illusion of selfhood. Extinction isn't a doorway to something else, it's just the lights going out forever. Every spiritual framework or philosophical system that promises otherwise is just folk psychology and primitive theory we cling to because accepting annihilation is psychologically unbearable. But unbearable doesn't mean untrue.

7 / 2new covidNew coronavirus subspecies with SARS-CoV-2–like mutation discovered in Brazilian bat

Scientists have identified a new coronavirus subgenus in a Brazilian bat with a feature that, as in the related SARS-CoV-2 virus, allows it to invade human cells, per a non–peer-reviewed study published on the preprint server bioRxiv.

Difference of only 1 amino acid
The researchers, from Japan and Brazil, collected intestinal tissue samples from 70 bats from three locations from May to August 2019 and digitally studied the virus's genetic sequence. The process revealed a distinct subgenus with a functional furin cleavage site (FCS) on its spike protein and a unique amino acid sequence motif that differs from that of SARS-CoV-2 by only one amino acid.

0 / 0botany question - what are the options for cross-hormone supplements?I am taking up botany as my retirement "thing" and have some experiments I want to try. before I do them, I want to find literature on previous work and I simply do not have the background to know how to phrase what I want to do. I have these ideas I want to try these:

1- kudzu has overtaken a large section of my neighborhood. I have an idea to harvest the growth hormones from it to feed my vining plants, such as mulberries, strawberries, and grapes. my rationale is how rooting hormone is either synthetic or extracted from a plant with a high root growth habit, though I am familiar with other approaches like capsacin. would harvesting and juicing those leaves in the morning to maximize yield make any noticable difference, as in, is this a common practice to cross hormones between plants for some advantage?

2- I want to grow some large amount of basil (for example), and harvest the leaves for their growth hormones in a grow room environment in a more or less hydroponic/kratky setup. I can reliably induce the temperature and light patterns to induce hormone production on the leaves, which I would then harvest, juice, extract, and then feed to a batch of other basil plants in a sort of cannibal farm for plants.

3- forcing lignification. from what I read about it, there appears to be some simple hormonal pathway to induce it, though I cannot locate literature as to how.

I think you can gather what I intend to do here. I suspect that it is possible to harvest the hormones responsible for the higher growth rate of something like kudzu, and feed it to a genetically similar plant. I am also interested in extracting saps/sugars/chlorophyll from donor plants to feed to experiment plants. what is this overall practice called, the efficacy of it, and if possible, some literature I can study on it?

TIA.

21 / 2normally i like to make up silly stories and larp as insane racists when i'm on 4chan, but this time i'm serious. autism researchers seriously need to look into the physiological effects of intoeing in certain subgroups of autists.

my hypothesis is that intoeing (inward rotation of the legs, which makes the toes point inward) can reduce certain fine and gross motor deficits in autism. other things need to be looked at like eye contact. my hypothesis is that eye contact, when measured in seconds of in-person conversation, will be positively correlated with the use of intoeing in either a standing or seated position.

other possible things to look for are:

(i'm just gonna copy and paste what i found.)

>Primary outcomes (mechanistic + high signal)

>Breathing mechanics

>Diaphragmatic excursion (mm): M-mode ultrasound during quiet/forced breathing.

>Thoracoabdominal contribution (% ribcage vs abdomen): optoelectronic plethysmography (OEP) or respiratory inductance plethysmography (RIP).

>Chest wall kinematics: 3D motion capture/OEP of pump-handle (AP) and bucket-handle (ML) rib motions.

>Spirometry: VC, FVC, FEV1, FEV1/FVC, inspiratory capacity at fixed postures.

Is modern science just a convoluted game of "Finders Keepers"?

I would like to propose that we stonewall all scientific awards related to any data that is withheld from an entire discipline for 30 days or more.
It does not matter what is in the HiRise data, this is too long. There will be NO Nobel for ANY finding in that data. The harm of withholding it from the rest of the astronomers on the planet, reduces the discovery impact potential.

Quick, justify the withholding of the HiRise imagery.
Hard mode, do not blame any of the following, as these reasons have NOTHING to do with the advancement of science or the scientific method, from a social human perspective:

1. Politics.
2. Money.
3. Ego.

9 / 1Most based experiment in historyThe Universe 25 experiment (1958–1962) remains one of the most haunting reflections of what happens when abundance meets social collapse.

American ethologist John B. Calhoun created a so-called “Mouse Paradise” — a habitat with unlimited food, water, and shelter — to study the behavioral effects of overpopulation. At first, the mice thrived.
They ate, bred, and lived without fear. But once the population reached around 600, something dark emerged.

Social hierarchies formed. The strong dominated resources. Mothers abandoned or even attacked their young. Males lost interest in mating or became violently territorial. Eventually, reproduction ceased altogether. The colony descended into cannibalism, isolation, and apathy, until it died out completely — despite everything they needed to survive being right in front of them.

Calhoun repeated the experiment 25 times, each with the same grim outcome.
His conclusion was chilling: when a society loses purpose, cooperation, and social structure — even in abundance — it collapses from within.

Today, Universe 25 stands as a stark warning about the balance between comfort, connection, and survival — a reminder that thriving requires more than just having enough to live. It requires meaning.

24 / 1> Researchers have mathematically proven that the universe cannot be a computer simulation. Their paper in the Journal of Holography Applications in Physics shows that reality operates on principles beyond computation. Using Gödel’s incompleteness theorem, they argue that no algorithmic or computational system can fully describe the universe, because some truths, so called "Gödelian truths" require non algorithmic understanding, a form of reasoning that no computer or simulation can reproduce. Since all simulations are inherently algorithmic, and the fundamental nature of reality is non algorithmic, the researchers conclude that the universe cannot be, and could never be a simulation.

6 / 1So, I see a lot of people complaining online about electronic harassment.

Obviously, that's just a common psychiatric symptom, although with some of the patents in the books, there is clearly the physics potential for electronic harassment to be real.

I could even electronically harass people for a few hundred dollars...

As Scientists, how do we address these overlaps between insane people's delusions and rare actual events of criminal conspiracy and illegal black budget operations?

Too many, well meaning, highly intelligent "Scientists" just close off their mind to complicated things that seem crazy, but imagine how limiting that perspective really is.

There are actually professionals who have to think about this stuff for national security, but yet, 100% of the people claiming to be electronically harassed are simply disregarded as crazy. Think about it. Some of them really could be telling the truth.

This is one of the few books that deals openly with this subject, because it is only happening among European and Asian populations. As you can imagine this is a slightly sensitive topic in a country built in the lie that all men are created equal. Do you have migraines, myopia and asthma? So most of the gifted children. The phenomenon looks genetic except that it violates Mendelian genetics because the kids are almost always 1st born. If you have ever been put in the gifted category you need to read this book.

What is the interpreter? There has to be _something_ that interprets something else, information by itself is static, it does not do or mean anything, it can contain an interpreter in any form but such interpreter would be static too. Therefore I conclude a duality: reality consists of an interpreter acting on raw information. What is the interpreter?

10 / 0Hi everybody im new to maths and am starting from elementary principles to build a strong foundation and am reading "Rational Numbers to Linear Equations" by Hung Hsi Wu yet cant wrap my head around this proof. Not only does he not exhaustively prove all cases for x and y, but he seems to just arbitrarily mess with one side of the equation and not the other to get it to do the thing he wants it to do.

e.g.

Case 1: If x,y > 0, then we resort to this theorem to prove that there exists a rational number z such that x =zy.

"Theorem 1.8. Given fractions A and B (B is nonzero), there is a unique fraction C, so that A = CB"

Now, if x is negative and y is positive, then Wu tries to rewrite the equation to conform with case 1, which will, by Theorem 1.8, give him a "z". Therefore, he says that if x < 0, then -x > 0. Then

(***) -x = z'y

Multiply both sides by -1

x = -z'y

Viola! z = -z'

However, I don't understand why Wu arbitrarily flips only the x and not the y in the step denoted by (***) above. That, among other things, confuses me.
