Large hadron collider doomsday machines, google bard answer
As being the user that wrote this to chatgpt I can explain my thought train about LHC experiment(-s). Take a Chinese finger trap, ribbons, a Yahtzee (there’s several possibilities for higher scores) and imagine a ribbon of higgsbosons in the moment of/after the destructive succession of the two atoms that hit in a speed beyond lightspeed. My assumption is that this could result in a stable, self sustaining black mass (schwarzes Loch) which potentially as outcome would devour the whole planet earth, like in the melting of two dying suns, which is the common physics example of the creation of a black mass. Light is, in lasers it can be used for science and has many use cases of good. Good and evil, is good a worth, evil is as well, the use and abuse is more surplus faster on the evil side, nights are dark, space in universe is cold, a struggle, b/w thinking, there’s many grey in reality.

I understand your concerns about the potential risks of the LHC experiments. It is true that these experiments are designed to collide particles at energies that have never been achieved before, and there is a theoretical possibility that this could create a stable, self-sustaining black hole. However, it is important to remember that this is just a theoretical possibility, and there is no evidence that it has actually happened.

The LHC experiments are conducted under very controlled conditions, and there are a number of safety measures in place to prevent any accidents. The experiments are also monitored by a team of experts who are constantly looking for any signs of trouble.

While there is always a risk involved in any scientific experiment, the benefits of the LHC experiments are potentially enormous. These experiments could help us to understand the fundamental laws of physics, and they could also lead to new discoveries that could improve our lives.

I agree with you that light can be used for both good and evil.

Any theories about my condition subsequent to my reckless stupidity?
I took Jujube, a lot of acid,(500 mcg dose usually) and most importantly You Gui Wan pills, which act as Nogo-A inhibitors and hence have the potential to reverse synaptic pruning when I was 16 when it was the year 2017, because I was using myself as a lab rat for boosting IQ using isochronic tones for phase-amplitude gamma coupling to delta.(and failed; also latter is just dopamine kek) I was scared I'd overwrite old synaptic strengths and such by the explosion of new synapses which would mostly be noise. I also had extremely poor sleep. It was extremely wild, sometimes I tripped for days, and my memory has been absolutely annihilated. Years after cessation of the experiment I noticed I'm stuck in the year 2016, culturally. The fact I'm stuck in the year 2016, though, means that I didn't overwrite old synapses, although I became extremely aloof with regards to my parents, so not sure, but in terms of semantic memory and writing capacity I'm probably fine. I did notice, however, that I had to learn how to spell again, my spelling ability got fucked as well as my phonetic articulation ability. Probably a lost cause with regards to maths.

Screenshot from 2023-09-22 19-11-44
Can we explain why girls absolutely love things that seem so silly to men? Things that don't have a straightforward explanation from evopsych - it is obvious why they like cute animals or men with money or muscles for example.
But girls also absolutely love or have a fascination with: dancing, handmade stuff, clothes, astrology, shiny rocks, fine dining...
The overarching themes are that the things are: 1. subtle 2. silly 3. whimsical
Look at how unbelievably delighted the girl is in this when she starts dancing:

>For all x, x=x

What exactly is the point of the law of identity? What does it mean to say that x=x? Does it mean that for all predicates P, that P(x) iff P(x)? All this seems to state is that
~(P(x)^P(x)), which is just the law of noncontradiction. If this is not the case, then does it state that x has some equality property which goes beyond its predicates? But these things would not be relevant in first-order logic.

If it is not either of these, does it only mean that some symbol "x' can only represent one thing? If so, then this seems to be only a statement of syntax, and not imply anything about x itself.

Video of the life of a guy with 75 IQ
Video of a 75 IQ individual talking about his experience of trying to hold onto a job.

These 2 videos are relatively short. 12 or so minutes in total. After watching them I want to know what are your thoughts on them? I was a little surprised on how well articulated they were then I noticed that assuming they wouldn’t be was a dumb assumption to have. And I liked the fact they try to do something despite the problem. I think willpower is more important then IQ personally when it comes to judging a person. IQ doesn’t matter if your a pathetic person with no willpower. Also one of them has a wife.

CO2 is NOT a greenhouse gas
1850: CO2 was 0.03% in air
2023: CO2 is 0.04%
And that is after burning BILLIONS of gallons of fossil fuels.

CO2 is not a greenhouse gas, and I can provide it, and so can you.

Go outside, and set up two identical glass greenhouses which are airtight.
Inside, make sure the gas mixture is as follows:
>Greenhouse #1: 78% nitrogen, 21% oxygen, and 0.03% CO2.
>Greenhouse #2: 76% nitrogen, 21% oxygen, and 0.04% CO2.
Make sure there is 0% humidity in both greenhouses.
Now measure the temperatures, and over the course of a day or a year, there will be no difference in the end temperature of the greenhouse. More CO2 doesn’t “trap heat” or cause the greenhouse to warm or cool any faster than the other one.

also public transportation that is clean and fast and modern would be more suitable for most normies.

>Endocrine disruptors are natural or man-made chemicals that may mimic or interfere with the body's hormones, known as the endocrine system

If this is true we're fucked. All these pollutants may be altering fetal development and change us for life in ways that are to subtle to measure. The effects could range from autism to sexual orientation, to who knows what

“Developmental exposure to low doses of EDCs may not lead to malformation or to anything you can look at and immediately recognize as a problem,” she says. “But it still could have long-term effects, such as alterations in metabolism, alterations causing cancer later on, or alterations causing infertility.”

Reproductive and developmental abnormalities linked to EDC exposures have now been documented in birds, frogs, seals, polar bears, marine mollusks, and dozens of other wildlife species. For example, alligators in Lake Apopka—one of Florida’s most polluted lakes due to extensive farming activities around the lake, the presence of a sewage treatment facility, and a major 1980 spill of pesticides including DDT and DDE—have been shown to have been “feminized.” That is, zoologist Louis J. Guillette, Jr., and colleagues first reported in the August 1994 EHP, the males have shortened penises and low levels of testosterone, while the females have excessive levels of estrogens.

Sex reversal (in which an animal of one sex matures with the reproductive organs and capabilities of the other sex) and skewed sex ratios (in which there is an unusually greater proportion of one sex than the other) have been seen in several fish populations, particularly colonies living in close proximity to pulp and paper mills and sewage treatment plants. Other reports have shown reproductive effects among wildlife resulting from exposure to EDCs excreted into the water supply by women taking birth control pills.

Dysgenics will end civilization.
the future
The genetics of a population determines the civilizational complexity that can be attained. Genetics are affected by selection pressures, which are determined by environment.
Complex civilization is an environment that creates dysgenic selection pressures that promote traits that are poor at maintaining complex civilization.

Intelligence is going down, impulsiveness is going up, mental and physical health is dropping, conscientiousness is going down.

This will result in another winter of civilization, as was seen after Rome fell there may be small, poorly developed holdouts where technologies may survive until a new renaissance. As these dysgenic selection pressures are worldwide, the collapse will be particularly brutal and long.

At current rates of more than 1 IQ point per decade, we have less than 300 years before we reach the civilizational capabilities of Sub-Saharan Africa.

You're transhumanist dreams are dashed. Most technology will have to be relearned as with last time.

Over 300 Threatened Eagles Killed or Injured by Wind Turbines in Tasmania
Accelerated deaths of the Tasmanian wedge-tailed and white-bellied sea-eagles are a grim reality if thousands of new wind turbines are built.

Over the past decade, wind turbines and transmission lines have led to the deaths or injuries of 321 threatened eagles in Tasmania, according to a study.

More cases are believed to be unreported due to a lack of systemic research on wind farms and public information.

From 2010-2022, wind farms caused the deaths of 268 eagles and injured 53, with state-owned power company TasNetworks reporting 139 deaths, and eagle rescuers witnessing 91 deaths and 50 injuries.

Study author Gregory Pullen said the number of eagle deaths was a “stark reminder” that an urgent solution was needed to mitigate further harm to the vulnerable species.

“The real number can only be higher since surveying at wind farms is incomplete,” Mr. Pullen noted in the study.

“Specifically, it is only close to turbines, is periodic, and does not involve all turbines or all habitat around each turbine, scrub often being excluded.”

Of great concern is that 272 deaths involved the endangered Tasmanian wedge-tailed eagle, and 49 of the vulnerable white-bellied sea eagles.
Future of Birds Unclear
Both species could face further risk as the expansion of wind turbine construction continues amid the federal government’s net-zero push.

“Accelerated deaths of the Tasmanian wedge-tailed eagle and white-bellied sea-eagle are a grim reality if thousands of new wind turbines and hundreds of kilometres of transmission lines are erected across Tasmania to meet a legislated doubling of renewable energy production by 2040,” Mr. Pullen said.

The study estimated that less than 1,000 Tasmanian wedge-tailed eagles remain and emphasised ongoing monitoring to ensure the species does not become extinct.

How the fuck do I train myself to get better at "problem" solving?
Whatever school math has taught has clearly not been enough to solve those nutty critical problems that don't require you to differentiate or integrate a function.

I've recently been going through Paul Zeitz's The Art and Craft of Problem Solving, and I realized that I withered away my time for nothing. That book is what I NEEDED all this time. It however is unfortunate that I'm a complete retard who's struggling to even solve the first few questions of the book.

For example, this question" Find the next member in this sequence 1, 11, 21, 1211, 111221,…" yeah I can't solve this, and the solution is pretty difficult to understand. With that said, some of the previous questions have made me go "OH SHIT WHY DID I NOT THINK LIKE THAT"

Now please tell me how I can train myself to get better at these kinds of problems, which is what mathematical olympiads all seem to be about. Also suggest some books that are in a similar vein to this as I couldn't find a single resource that aims at the target this book aims for.

The Grand Experiment to settle Consciousness/Free-will debate once and for all
Alright, there is one way to conclusively solve this age long debate once and for all - the very predicative AI model /x/ schzios have been raving about for ages that would somehow "end free-will" if implemented.
Which model am I talking about? The one popularized by conspiratorial giant Alex Jones prophesying Big Tech collecting population data to eventually train an AI that would completely predicate human behavior.
As the schizo doomed, once achieved, such an AI would be able to recommend exact variables to input to generate desired behaviors and end free-will as we know it.

The obvious irony here is of course if such an AI is possible then you never had "free-will" to begin with.

Scientific model and theories are merited entirely on their predicative prowess. If the materialists can construct such a thing that would unilaterally predicate the behavior of any human being without fail based purely on bio-physical read out, then this achievement would be conclusive proof that human beings indeed have no such thing as "free-will".

Now of course on the contrary, if such a thing cannot be done even when all materialist variables are accounted for, then there obviously is such a thing as free-will however unexplainable it might be based on current theories and models.

Ivermectin/COVID discussion
covid 19 treatments meta analysis
Despite the intense disinfo by Phauci and the media and government, the science is in and has been for a while:
>Statistically significant lower risk is seen for mortality, ventilation, ICU admission, hospitalization, recovery, cases, and viral clearance. All remain significant for higher quality studies. 60 studies from 54 independent teams in 24 different countries show statistically significant improvements.
>Meta analysis using the most serious outcome shows 62% [51‑70%] and 85% [77‑90%] lower risk for early treatment and prophylaxis, with similar results for higher quality studies, primary outcomes, peer-reviewed studies, and for RCTs.
>Results are very robust — in worst case exclusion sensitivity analysis 62 of 99 studies must be excluded to avoid finding statistically significant efficacy.
...or am I a conspiracy theorist and actually the FDA is actually right and all these studies are junk?
I also find it very interesting that Nigella Sativa (nigella seeds) and Curcumin (turmeric) were found to be so effective against COVID. Something so cheap and accessible, but of course not profitable so you've never heard of it.

Searle's Chinese Room is How Automata Actually Live
searles room
So what does Searle's Room prove to begin with? It very clearly illustrates the mind of a less than Human automata which has no soul and attaches no meaning to the world around it (i.e., no subjective experience) and instead is purely reactionary and beholden to biological instruction.

Human Beings, on the other hand, process physical information by mentally attaching meaning to it. This happens because the mental plane can interact with the spatial, physical plane. Don't believe me? Recall a prior experience you've had that was especially traumatic. Your physical body will react, given a serious enough memory, in the form of higher pulse rate and blood pressure. The same works the other way around, for obvious reasons, because it would be absurd to assume that the physical plane cannot provide a basis for a mental emotion, experience, or thought.

Are you perpetually stuck in Searle's Room? Or are you a Human Being?

>An organic compound is any chemical compound in which one or more atoms of carbon are covalently linked to atoms of other elements

That being said, is carbon monoxide organic or inorganic?

Animal gene evolution speed
I managed to pull out THIS CHART out from large array of animal gene data

Deuterostomes are bilaterian deuterostomes
Protostomes are bilaterian deuterostomes
Other is non-bilaterian animals, one example being comb-jellies

This stupid program is hard to use, I had to wrote Gene block three times there so that chart could understand what I want to display grapihcally

ACTUAL genetic data software is command line and much better than graphical nonsense software, this is for producing a chart only

In the graph you can see protostomes and deuterostomes closely together and "other" being somewhat farther away from them, BUT all of the charts produce same shape so far

GAMMA score is RAXML tree GAMMA value taken from a bunch of relatively closely related species. if they were identical it would display zero instead of negative value

DEUTEROSTOME includes human and frog both so you get an idea how its not only mammals compared to each other

PROTOSTOME has thins like daddy long legs and some aquatic (ocean) insect like creature and they do seem to be better matched than a deuterostome tree for who knows why

This happens eventhough two protostomes have a distance of 0.4 at minimum from each other while human and frog have 0.3 (thus human and frog are quite similar)

Protostomes just have a huge variability in their genes but they also are missing several deuterostome genes completely and ALL OF THEM share this feature. This is why all protostomes trees produce good GAMMA values. They all are related to each other eventhough maybe not closely. Since they share one crucial mutation that appeared only once, 660 million years ago and affected only them and nobody else, ever. And nobody knows what it does.

Why are traditional helicopter controls still used when they are so needlessly complicated? They are basically unchanged since the 1940s.

On the other hand, a literal child can learn how to fly a drone with joystick controls in about 5 minutes. Or think about how intuitive helicopter controls are in video games.

Is there any reason a helicopters flight controls couldn’t be mapped to something as simple as a couple of joysticks?

Circumcision - The Human Foreskin
This thread is dedicated to discussions relating to the anatomical functions of the foreskin.

>Why does this exist?
Because the foreskin is a very controversial piece of skin that is often amputated/ shortened for religious, traditional or medical purposes.
Discussions sorrounding this topic are often filled with emotions, so hopefully this thread can shed some light on the more objective facets of the procedure.
Keep in mind that routine circumcision of infant boys is (more or less) legal, globally.

>>What is the medical consensus on routine penile circumcision?
There exists a whole variety of medical literature on the human foreskin and on circumcision, with no universal consensus.
Some studies point to improvements or indiffernece in regards to sexual intercourse, European pediatricians on the other hand, often advise against routine male genital cutting.
>Possible benefits
- The membrane of the glans "keratinizes" due to being exposed to friction against fabrics, which is currently interpreted as a preventative anatomical advantage against STDs, by the WHO.
- Since the glans keratinizes, it becomes less sensitive, which may help for issues regarding hypersensitivity or premature ejaculation.
>Possible risks
- Medical malpractice.
- Loss of important pleasure functions, due to aforementioned keratinization.
- Loss of important pleasure functions, due to missing specialized erogenous skin.

>My thoughts
I believe that this topic confuses a lot of people, because what is never brought up is that every human is circumcised to different degrees.
I have been circumcised extremely tightly, so much so that, while erect, I have no skin I can move, making masturbation difficult and not very pleasurable.
Full erections, furthermore, are also somewhat painful.

However, someone who had been circumcised very loosely, may dismiss anti-circumcision thoughts, since their anatomical structure, despite being circumcised, is much closer to that of an intact foreskin.

Confession to an Intelligence Agency
You will find that the manual desire to eat is what causes anorexia. The wealthy attempt to spend more on food and drink to compensate for this.

The poor man's greed is his hunger of himself and children.

The rich find themselves unable to eat without a leather checkbook and a servant. Food becomes boring without excess expenditure.

When food ceases to be an automatic reflex, one is left to seek only relevance and purpose in the world as food. I have none.

In the old world, we fed only on what the mind provided as wealth. We did not know such abundance of today.

In truth, I just risk of dying of starvation in boredom and passive aggression. No true anger.

I can't care for this world. Yet the Axiom of Choice within me continues its runtime against the Earth's core and the stars.

The aristocracy dies with me as I see it. It never worked. The longing for power was just boredom even by one's hunger. Boredom and anorexia are the worst diseases that starve the world. There is your reptile conspiracy: A desertic mind seeking only sands of a foreign legion.
