Can anyone give an unironic reason why we would ever need to know how to turn a sphere made up a self phasing material inside out?

Anyways, what do (you) think the average IQ of /sci/ is? Are you all midwits larping as geniuses? What about other boards?
I still can't believe that IQ is normally distributed. For every 110 iq person, there is a 90 iq person. For every 120iq person, there is an 80iq person. For every 150iq person, there is a 50iq person.
Of course this is logical, but 70iq seems so much dumber than 130iq seems smart.

Also they are only interested in "learning by immersion" or some bullshit like that, so it's also a stupid inneficient way of doing stuff, if it worked the US diplomants and the CIA would teach languages that way

Taking that into account as well as individual reports and recordings like vid rel, why isn't this bigger news?
According to Calhoun, the death phase consisted of two stages: the "first death" and "second death." The former was characterized by the loss of purpose in life beyond mere existence — no desire to mate, raise young or establish a role within society.

I think it’s crazy that we know so little about handedness.
Why is it still Blue ? I took around 10 mg a day where the recommended doses are around 2mg/kg body weight Bottle says one drop = 20 mg so I took no more than 10 drops a day for a few days. Also made me psychotic or at least let me recognize my brain wasn't responding to my surroundings correctly..

>Name a language that contains the homophone pairs TWO/LOUSE and MANY/DOG.
It seems like a simple task but current AI just bloats itself with shit upon presenting this query. It always defaults to scattergunning languages (usually Mandarin, Hawaiian and French) and dragging itself through a big loop of "let's try language X because it has feature Y" rather than actually using the raw datasets it has access to that would immediately provide the answer.
Pic is my favourite time-wasting "thought" whether two words with 0 shared letters constituted a homophone in a phonetically transcribed language. Whoever programs these things needs a harsh reality check they can't do realworld tasks required of them and they can't do bulk data analysis.

>Protocol
It's a two step process.
Step1:
500mg Curcumin
500mg or so Tributryn
Take about a dropper full of B12.
Wait an hour.
Then, think of this as a balanced dose to start the reaction.
Step 2:
300mg Liposomal Apigenin
Another 500mg of Tributryn
About 500mg of either NAD or some combo of NAD and NMN.
Repeat step 2, 2-4+ times a day.
One week on one week off to avoid T cells exhaustion.
Ultimately this is your immune system first reprogramming itself and then going out to the rest of you. The T cells are able to identify cell wall markers where issues are the most severe and those will need to be targeted first before any specific issue.
Give it a little wiggle room if you don't need as much NAD or Tributryn. NAC is a good add in as well while doing this if you have a history of smoking or lung problems.
everyone who procrastinates understands that it's completely irrational. so then why is procrastination such a universal struggle?
do other intelligent species procrastinate as well?
Do animals also vary facially to the same extent as us? What about insects?
Any suggestions for study material?

Skill/performance is determined by consistency within the long run, maybe it's time to admit that IQ tests are bullshit if you think that practice is considered "cheating"
If the universe is infinite couldn't we follow stars back to the origin/point of the big bang? For example if our star is 13 billion years old, but a distant star is 12 billion years old wouldn't that indicate the direction the big bang came from?
And if we were to survive for billions of years wouldn't we eventually need to follow the "wave" finding younger and younger stars so we're not in complete darkness?
But it started making electrical noises in the spot the flame was and then started burning bright white like an electric flame. A few seconds later sparks flew out from the settings panel and the entire oven died. What the hell just happened.
bounded space,
unbounded space,
finite volumes,
unbounded time,
bounded time?
I was chatting with someone about time and space when they told me that I didn't really get the concept of space. I thought I understood it, but he insisted that my idea was more related to volumes. That’s when I realized he was right, I didn’t really know the difference between volume and space.
naturally we conceive of all space as a volume, since no one can imagine what infinite space is like.
but I still don't quite get it, what is the difference between a bounded space and a finite volume? they sound like the exact same thing.
In my opinion, our earthly powers of logic and reason are insufficient to answer such a question.

Its the same for composite particles like protons, the internal particles are considered linked and subject to collective rules, but not the particles of two random protons on two different planets. They are just disconnected.
How does this work formally? When do multiple particles become "a system"?
When they become entangled?
What do you call billions of entangled particles? A condensate?
A person on the Moon cannot jump high enough to escape its gravity and go into orbit.
The Moon’s escape velocity—the speed needed to completely break free from its gravity—is about 2.38 km/s (or 2,380 m/s). Even with the Moon's lower gravity (about 1/6th of Earth's), a human can only jump a few meters high at most, reaching speeds of maybe 3-4 m/s. This is nowhere near enough to escape the Moon’s gravity.
Clearing your orbit is a stupid fucking criteria for being a planet. You're telling me if Mars were exactly the same but had large debris around it, it suddenly wouldn't qualify as a planet anymore? How do you even fucking quantify this, at what arbitrary line do we declare a certain amount of debris is too much. Holy shit they were right about Pluto
Nowhere else in the universe does this happen.
Overtime I built up an idea based on my experiences, research, papers, experimenting and I found a personal solution that appears to be working for me to solve the problem of mental health in general (comorbidity of several issues), which may end up being of help to cancer or other physical problems that haven't been found yet. I'm so far building the results, which I'm actively experiencing the improvement of beyond what placebo. I just don't know how long it will go on for
Overall, I need data proof- even if I have a result. I can attempt to find the pattern or formula that can be used universally to solve the problem if it's how I think it is- or at least help complex cases such as mines (not my words)

#1. Quantum Tunneling Ligands
- Mechanism: A molecule engineered to exploit quantum tunneling effects to bypass traditional binding kinetics. By optimizing electron cloud configurations (e.g., aromatic stacking with π-π interactions in the mu-opioid receptor’s binding pocket), the ligand could "teleport" into place, requiring vanishingly small concentrations to trigger receptor activation.
- **Potency Amplifier**: Theoretical models suggest quantum-resonant molecular shapes could achieve binding affinities **1 billion times** greater than carfentanil.
#2. Covalent Allosteric Nanobinders**
- **Design**: A hybrid molecule combining ultra-high-affinity opioid agonists (e.g., a fentanyl analog with fluorinated aryl groups) and CRISPR-derived guide RNAs that bind irreversibly to opioid receptor DNA. Once attached, it forces continuous transcription of receptors while simultaneously activating them.
- **Effect**: Permanent receptor activation at picogram doses, with lethality thresholds approaching **single-molecule levels** in neural tissue.
#3. Multivalent Fractal Dendrimers**
- **Structure**: A dendritic polymer with thousands of fentanyl-like ligands arranged in fractal patterns, each branch terminating in a modified carfentanil derivative. The fractal geometry allows simultaneous binding to clusters of mu-opioid receptors, leveraging cooperative effects.
- **Potency**: Synergistic binding could amplify potency by **106–108×** compared to monomeric carfentanil.
#4 Biohybrid Peptide-Nanoparticle Conjugates**
- **Platform**: A synthetic peptide mimicking the enkephalin structure, fused to a lipid-coated nanoparticle loaded with carfentanil derivatives. The peptide acts as a "Trojan horse," hijacking endogenous endocytosis pathways to deliver thousands of agonist molecules directly into neuronal cytosol.
Please give your opinions on these theorized Super Opioids
and that machine would be a closed-in system where you put in cellular materia and it then extracts DNA from
complete DNA data is then represented as a savefile that can be opened in Windows or Linux PC for further study
hint: you put in human skin cell in there and then you know persons entire DNA
the poorest people ever cannot buy even 500 USD appliance but anyone with 500 USD smartphone can save a few months to buy DNA computer as well, they obviously have somekind of job
in addition someone could simply buy a device that costs 10 000 USD with loan money if he can find clients who are willing to pay him 100 USD or something to get someones DNA onto computer
you just need a few hundred clients then
you cant ask too much for this kind of stuff from those shady clients either

ive been thinking about brain scans and brain replacements and i've come to the conclusion that personal identity is preserved through a heirarchy of continuety.
>Perfect continuity (Normal life, gradual change, no real disruption) = Definitely still you
>Minor disruptions (Sudden Memory loss, body alterations, personality shifts) = Still you, but different
>Radical change, but unbroken chain (Gradual Brain replacement, ship of Theseus case) = Still you, just completely transformed
>Instant duplication with destruction (Teleportation) = Copy, not you
>Instant duplication without destruction (Cloning, Brain scan then copy & paste to new body) = Definitely not you
i'm curious to see peoples perspective on the matter.
I want to know more about physics, but I don't have time to study a PhD.

For context, I applied said spray to my bathroom walls/ceiling around 6 days ago to deal with some mould. I didn't ventilate the room during application (stupid, I know) and experienced some significant throat and eye irritation during the job.
I did ventilate the room extensively later on and made an effort to wipe away any remaining residue on the surfaces on two separate occasions, however, the smell lingered for days throughout my house and I have a kind of lingering chemical taste in my mouth sometimes.
Would any remaining residue release harmful vapoure after such a long period or an I in the clear now?

This idea may appear erratic. So, please let me room to explain.
Let’s consider the parent generation. Each parent has a 50% rate of passing on their genes. Basically, yes. However, there is a way for a selfish gene to further increase its chances of being passed on, namely if both parents are related and thus already share a certain percentage of genes.
So, from the perspective of a selfish gene, there must be a trade-off between the harms of inbreeding, such as the activation of harmful recessive genes or a lack of genetic diversity, and the benefits of relatedness through an increased chance of being passed on. Formally, one can write: given a certain degree of relatedness, c is the chance of harmful mutations and recessive genes, etc., while t is the chance of passing on as many selfish genes as possible.
t >> c
How you any idea how formally caculate this?
