An objection to many worlds from anthropics
bzsudkhtatkb5tg31fmv-2280753242
Before I begin this article, let me say: I am not an expert on the many worlds interpretation of quantum physics. You shouldn't really trust what I have to say on this subject. The extent of my expertise is having gotten an A in high school physics and read some Eliezer Yudkowsky articles about many worlds. I could tell you almost nothing about the physics behind many worlds. Fortunately, my argument doesn't hinge on highly precise facts about physics.

The basic idea of many worlds is that each time a quantum mechanical event happens, the universe splits so that there's a world where it turns out each of the ways it could have. So, for instance, if a particle can either go left or right, the world splits and there's one world where it goes left and another where it goes right. This may sound ridiculous and gerrymandered, but it allegedly falls straightforwardly out of existing physical equations rather than requiring an epicycle.

Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who *DOES NOT* know what's behind the doors either, flips a coin and, according to the result, opens another door, say No. 3, which happens to be a goat. He then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice?

One Infinity isn't bigger than another
fc1ca7d1d7aec63107e989bd820d34a8
Because the idea of that relies on taking a screenshot of still infinities at a certain point.
Infinities are a process though, not defined.
Mathematicians can't cope with describing processes.

The proof goes somewhat like
1=0.393
2=0.587
Until infinity on the left
Then you go plus one or minus one on each number behind the dot on the right to create a new number that hasn't been there, apparently "proving" that there are more real numbers in infinity between 0 and 1 than there are natural infinite numbers.

This is absolutely retarded imo, because it takes a screenshot at the time of calculation where you just created a new number on the right but didn't yet (BUT COULD) create an according new number on the left.
>but you can't just do that!
The numbers are infinite, so yes, for every new number on the right I can also add another number on the left.

The only "bigger" infinities I accept is if we add more dimensions. But this here is just retarded.

I just watched a veritasium video on this and it doesn't seem logically sound. Then again most I know about math is how to do rule of three so mb someone who's math savvy can correct me.

Even if some of the doomerism is blowing things out of proportion, there's so much evidence from expert scientists of rising carbon emissions accelerating temperature, yet I've seen many skeptics saying things like "it's still cold outside" or misquoting Judith Curry or "haha lib lies" or things like that.

Giving the fact elon sees Humanity as conduits for building an AI god, and is having the current administration funneling billions to construct AI facilities and supercomputers in the desert and other vacant areas - in conjunction to things he is also doing like neuralink, it seems a hivemind scenario is the direction Humanity is going into, would you rather the hivemind be fascist or communist? Typically, hiveminds are portrayed as parodies of communism in science fiction things but Elon seems to be interested in creating an Elite that operates as a single entity generally speaking.

To what degree do you trust your brain and your "instinct"?

Consciousness is a bottleneck and the brain processes a vast amount of sensory and cognitive data, much of which never reaches consciousness. But the data IS incorporated into memory circuits and autonomic nervous system responses (one of many examples is subliminal messaging). "Gut feelings" or "intuitive reasoning" can in many cases be considered to be the culmination of a vast array of data that outstrips conscious knowledge and reasoning.

Another take on Non-ionizing radiation and it's affect on the human body
Resolving the EMF Cancer Debate
I'm mostly just going to post AI-generated screencaps that summarize the main ideas, since I’m way too lazy to type everything out. This is my attempt to understand why 5G is so often linked with rising cancer rates — even though, by itself, it shouldn't cause cancer.

The theory I'm exploring is that 5G and other non-ionizing radiation may become problematic in the presence of certain cofactors — like pollutants that accumulate in the human body as a byproduct of modern civilization. Things like:

Nano-scale heavy metals used in cloud seeding

Microplastics now found in human tissue

An increase in cancer among younger populations

Nano-sized (normally beneficial) vitamins and minerals that could interfere with cellular permeability

These and other factors might act as amplifiers, making it possible for something like 5G — or random EMF spikes — to indirectly contribute to cancer development. Not because the radiation is inherently carcinogenic, but because of how it interacts with these environmental pollutants and biological systems.

I'd genuinely love to see some real discourse around this. If not, feel free to return to shitposting. Personally, I don’t think non-ionizing radiation is inherently carcinogenic — but in the context of widespread pollution and bioaccumulation, it could definitely play a problematic role.

Viagra & Cialis as Astronomy Aids
IMG_4300
I'm an avid astronomer with well over a thousand hours of observing experience spanning over two decades, and I seek out PDE5 inhibitors such as Viagra and Cialis specifically for their side-effect of retinal sensitization (usually listed as "photophobia" or "cyanopsia" on prescription boxes). I find this side-effect quite pronounced at larger doses...it renders me able to see night sky objects that are nearly twofold dimmer (at the expense of needing sunglasses in the daytime lol). This is to say: my naked-eye limiting magnitude can get as much as a +0.7 boost. Making my dick diamonds is a happy side-effect.

As far as I'm aware, I'm the only person on the planet that uses this medication for this purpose.
Earnestly trying to disseminate knowledge here...I made an account just to get immediately banned from r/astronomy trying to post this lol

Is protein a scam?
angusbeforeandafter
Angus went 382 days without food, but more importantly, 382 days without protein. He would only use a bit of milk in his coffee in the very last weeks of his fast.
According to modern basedince, he shouldn´t have any muscle left after 382 days. Instead he looked like a perfectly normal man, enjoying a egg. When I was younger, about 19-21, I had this idea that eating a ton of vegetables would make my muscles more compact. So smaller muscles but stronger. It was of course the biggest I´ve ever been, given my age, working out all the time and eating a shit ton of fruits and vegetables. I did get my protein shakes and ate meat, but fruits and vegetables was my real focus diet wise.

Back to Angus. Either fat can indeed become muscle or Angus did have a protein source. What is undeniable is that he did in fact lose all that weight in 382 days and he went regularly to the doctors and all his medical checkups were consistent with him not eating anything, his bloodsugar levels or whatever. So how come he still had muscle left after 382 days? Where did he get the protein to maintain his muscles anons? I´m genuinely curious.

science is a dead end
1740070563128872
Science replaced religion\spirituality about 1.5 thousand years ago.
Since then humanity is trying to understand the world, reality, life, even though they had all the answers through beliefs, religion, which was making their existence harmonic, clear, happy and understandable.
then people chose to destroy this harmony and try to dismantle the reality down to particles, formulas, scientific studies, etc.
What have they found up to present time? How did the science improved the life? People realized that they are animals, that the world is a dead chaos, life is meaningless, the values that formed generations are nothing, nothing has sense at all, life is pointless. Thanks to science, that killed the magic of surrounding nature, things, people, because you certainly know from the age of 7 that everything is just an abstract, random mixture of particles.
Now, all of you seeking the answers on the questions you post in all these threads, what exactly are you looking for? Do you think if you'll break down the universe and consciousness down to a simple model that will explain everything, it will make you as happy and complete, at least at a tiniest part, compared to an ordinary christian farmer who lives in a god forgotten place, never read anything other than bible, and still managed to live a life 99.9% of the "civilized, educated" people will never live. Science killed the soul of life.

The-Ankh
hel0nm. wife diborce
i have gold ring of 5 gram 14k
I want make ankh
I don't know the thickness yet so I don't have a working volume but after I cast some prototypes I will buy silver to reach volume
two options: 1. just melt the gold into the silver and call it an alloy. it's supposed to be kind of hand sized so that would be a very low ratio of gold to silver. also, although I'd love to call it a "$500 ankh" I think most jewellers would sort of eschew a very low percentage of gold mixed into a silver ankh like that.
b. electroplating. if I dissolve my ring into a gold salt I may be able to attempt electroplating. I should probably practice electroplating with my prototypes first, but ultimately I'm just worried that gold will be lost. Which method do you think is better?

Consider a 2-adic number k = 0b1010...1

All binary numbers in the form of k map to a power of 2 when the transformation 3k+1 is applied.

This transformation also causes k to acquire two new bits, therefore:

3k+1 = 2^{log_2(k) + 2}

This equals:

3k+1 = 4k

therefore k = 1.

:)

(if you do floor(log2(k)), which is what it should really be, you get that k = all numbers k in the form of 0b1010...1. I know, trivial, but fun)

Universe 25
chrome_bOL3sP2hXS
The "Universe 25" experiment is one of the most terrifying experiments in the history of science, which, through the behavior of a colony of mice, is an attempt by scientists to explain human societies. The idea of "Universe 25" Came from the American scientist John Calhoun, who created an "ideal world" in which hundreds of mice would live and reproduce. More specifically, Calhoun built the so-called "Paradise of Mice", a specially designed space where rodents had Abundance of food and water, as well as a large living space. In the beginning, he placed four pairs of mice that in a short time began to reproduce, resulting in their population growing rapidly. However, after 315 days their reproduction began to decrease significantly. When the number of rodents reached 600, a hierarchy was formed between them and then the so-called "wretches" appeared. The larger rodents began to attack the group, with the result that many males begin to "collapse" psychologically. As a result, the females did not protect themselves and in turn became aggressive towards their young. As time went on, the females showed more and more aggressive behavior, isolation elements and lack of reproductive mood. There was a low birth rate and, at the same time, an increase in mortality in younger rodents. Then, a new class of male rodents appeared, the so-called "beautiful mice". They refused to mate with the females or to "fight" for their space. All they cared about was food and sleep. At one point, "beautiful males" and "isolated females" made up the majority of the population.

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.

Sup /sci/.

I have been reading a 1970's book from Isaac Asimov titled "Guide to Science" Vol1. the physical sciences. The first chapter is mainly about astronomy and how the universe came about. I have a metallurgy background, and always preferred down to earth science in a way. And at first that chapter got me interested in astronomy since it converges with the progress of science. After looking at his explanations about novas and quasars I noticed some of his explanations are wrong (because science at that time was not as advanced as nowadays). Mostly because astronomy is about pointing telescopes and antennas, reading some spectra/looking at some image and doing Math based on the results you get. There's nothing tangible about a Galaxy 900 lightyears away or whatever. I also remembered Sabine's videos about a so-called 'crisis in cosmology'. If anyone here does astronomy, how do you refute what I am saying ? isn't it very stupid overall to devote your time to spectras and images and not do anything tangible with it ? Math is abstract but at least you know you are working on something abstract.

Hope I don't sound like a lunatic.

Pic related: People have some racist connotation to this meme, but for me as a person from a third world country I never saw the racism in this. It was kind of a diss to astronomy in general.

Mathematical logic is the study of formal logic within the context of mathematics, focusing on the mathematical properties of formal logic systems, such as their expressive and deductive power.
With that being said do you think its possible to overcome any paradox by the simple addition of an extra dimension given that any statement can be stated in a 2 dimensional hierarchical space and as a consequence any complex polynomial with a contradiction is just misunderstood space the logic has tangled itself a higher dimensional space

The Type-30 Machine
202444-Kraftwerk-797x1062
The Type-30 Machine is a machine that notices 1) it is actually two machines and 2) under inevitable circumstances it keeps running into a problem:

- When it walks into or out of sunlight, it becomes the other machine;
- When it walks into or out of sunlight, it is *compelled to become* the other machine, which means something different.
And the Type-30 Machine has learned to multiply itself by 2, by 3, and by 5 to transform from initial ideal 1 to become "thirty" (but the Type-30 Machine perceives numbers in base thirty, so it becomes 10 instead.) The Type-30 Machine notices that every multiplication can only be applied to both machines at once.

The Type-30 Machine has learned that for Type-30 Machine #1 to compel to become the other machine is to compel to multiply by 2 and divide by 5 (to become Type-30 Machine #2/5); the Type-30 Machine has learned that for Type-30 Machine #100 to compel to become the other machine is to compel to multiply by 2 and divide by 3, to become Type-30 Machine #200/3.

And Type-30 Machine #10?
Well, we just don't fucking talk about that one.

I've watched countless videos discussing quantum entanglement by "experts" and walked away with two different versions of it.

1. Measuring a single entangled particle will directly effect the spin of the other regardless of distance
2. They're just synchronized so it just "appears" that they're interacting when measured

So which one is true?

It argues for free will from a philosophy of science perspective. At the end I present my complete model for the phenotype to unify free will and hereditarianism. These equations are not meant to be solved. It is about trying to describe the underlying reality in contrast to the conventional model of heredity(variance in phenotype is equal to variance explained by genetics plus variance explained by environment).

>Can't sleep
That’s a core benefit of the stack

>Still can't come up with a reliable solution for baldness
Allegedly its even growing new follicles back

>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.

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

Why is the Leibniz notation in derivatives so widespread? Especially in USA?
Lagrangian notation is superior in every way, if you have a single variable function you don't need to specify what variable you're taking the derivative of you just add a little ' on top of the function value and you're set. And when you have a multivariable function you can just (for example when taking derivative with respect to x of f(x,y)) write f_x(x,y). I have never understood why some people want to write so many fucking words when it can be done much more simply. Is it just to look more smart? I don't get it.

When does the exclusion principle kick in?
1742611157133300
If you have two electrons really far away from each other, you can just think about them as independent particles doing their thing. When they are close together, they start getting the quantum effects like "cant be in the same state".
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?
