Ok, so 1/3 is 0.33333 forever. 2/3 is 0.6666 forever. So, if that's the case, why is 3/3=1 and not 0.99999 forever? Where does the last little bit get added to 3/3 to have it equal 1?
scientifically speaking, what was his goal? and what did he die of?
How do you respond without sounding mad?

Mods regularly ban Anons for geocentrism and young earth creation when these are true and scientific.
Perhaps we can compromise and not talk about divine revelation.
But this board cannot be /sci/entific if it bans the truth on two huge topics.

JOHN GABRIEL WILL SAVE MATHEMATICS
DON'T BELIEVE ACADEMIA
Today's date is Feb. 18th, 2025. The current time is 11:23 AM, EST. Right now, several hundred people in San Francisco and Beijing are racing to build the most consequential technology ever invented. Whoever gets to it first will have the power to shape humanity's future for better or for worse over the next centuries. Our governments and the public remain dangerously ignorant of both the technology and its implications. First to AGI controls the world.
Assuming the current rate of progress holds, we will reach AGI before the decade is out.
This is where you are.

If A effects B it's only because A and B are the same thing, what means are there for A to effect B if both are discrete? none. A and B are merely a low resolution, small dimensional slice of the whole, a cognitive limitation by a brain.
In each puzzle, 2 panels are missing.
You must select 2 of these panels—in the correct order—to complete the pattern. ( 46 is different from 64)
It is possible for the same panel to appear twice (e.g., “11,” “22,” etc.).
None of the puzzle require external resources. You do not need any special knowledge to solve these items. None of the patterns are cultural.
Lastly, you need to provide both the answer choice and the explanation. Feel free to use drawing tools to aid with your explanation. I encourage it so that it is clear to everyone what you are saying.

this seems like a world ending technology...
Let me explain. This puzzle is a favourite of mine. There are 2 parts to it, one which is fairly easy to spot and another one which complements the first pattern in an abstract sense. The second pattern seems very hard to spot. Most people have gotten to the correct answer through a design flaw. There is an alternative pattern for the 2nd part which produces the same result as intended, but it is far less clever.
I have 2 difficulty ratings for this problem for this very reason. Good luck.

why isn't falling asleep as easy as going to the the toilet, eating, drinking or breathing?
Either that limit is undefined or 0.999... does not equal 1. You can't have it both ways.
im doing some linalg
is the meaning of existence about throwing life into a black hole?
Suppose that there exists [math]r \in \mathbb{R}[/math] such that [math]r = 0.999...[/math].
From the first digit being [math]0[/math] we have that [math]1 > r[/math]. From the second digit being [math]9[/math] we get that [math]r \geq 9 \cdot 10^{-1}[/math], from the third digit being [math]9[/math] we get [math]10r - 9 \geq 9 \cdot 10^{-1}[/math].
More generally we have [math](\forall n \in \mathbb{N}) 10^n \cdot r - (10^n -1) \geq 9 \cdot 10^{-1}[/math].
Subtracting [math]1[/math] from both sides we get [math](\forall n \in \mathbb{N}) 10^n \cdot r - 10^n \geq -10^{-1}[/math].
Factoring out [math]10^n[/math] and swapping all terms to the opposite side we get [math](\forall n \in \mathbb{N}) 10^{-1} \geq 10^n \cdot (1-r)[/math].
Since [math]1 > r[/math] we have that [math] 1-r \neq 0[/math] so we can multiply both sides by [math] (1-r)^{-1}[/math]: [math](\forall n \in \mathbb{N}) 10^{-1}(1-r)^{-1} \geq 10^n[/math].
Letting [math] k = 10^{-1}(1-r)^{-1}[/math] we get [math](\forall n \in \mathbb{N}) k \geq 10^n[/math].
But this leads to a contradiction since [math](\forall n \in \mathbb{N}) k \geq 10^n \Rightarrow k \geq 10^{\lceil k \rceil}[/math] and [math]10^{\lceil k \rceil}> \lceil k \rceil > k[/math].
But if [math]0.999...[/math] is not a real number how do you determine if some collection of digits represents some non-negative real number?
Well, it's very simple. First, a digit representation is some function [math] f : \mathbb{Z} \rightarrow \{0,1,2,3,4,5,6,7,8,9\}[/math].
Now one of these functions represents some non-negative real number if and only if it satisfies these two conditions:
[math]1) (\exists N \in \mathbb{Z}) (\forall n \in \mathbb{Z}) (n < N \Rightarrow f(n) = 0)[/math] This ensures that every number represents some finite quantity.
[math]2) (\nexists N \in \mathbb{Z}) (\forall n \in \mathbb{Z}) (n > N \Rightarrow f(n) = 9)[/math] This avoids the above contradiction.

Abstract
We propose that the photon, a massless perturbation from a 0-D singularity, exhibits spontaneous symmetry breaking inherent to its geometric structure, modeled as a Gaussian wave packet with finite amplitude and infinite wave number. This breaking induces a hyperbolic angular momentum effect, modifying the stress-energy tensor ( T_{\mu\nu} ) with a rotational term. We rigorously derive this modification and demonstrate that it generates spacetime curvature, explaining Cosmic Microwave Background (CMB) anomalies: large-scale temperature asymmetries, quadrupole-octopole alignments, and polarization shifts. With a coupling ( \alpha = 10^{-3} ), the model predicts CMB lensing deflections (( 10^{-30} , \text{rad} )), B-mode power (( 10^{-33} , \mu\text{K}^2 )), and vacuum energy shifts (( 10^{-20} , \text{eV} )), testable by Simons Observatory, Fermi-LAT, and BEC experiments. This framework ties photon properties to primordial dynamics, offering a novel paradigm for quantum-gravity interactions.
Introduction
The photon, a massless particle in quantum electrodynamics (QED) and general relativity (GR), is typically modeled as a plane wave following null geodesics. However, persistent Cosmic Microwave Background (CMB) anomalies—large-scale temperature asymmetries [1], quadrupole-octopole alignments [2], and unexpected polarization patterns [3]—suggest deviations from the standard ( \Lambda )CDM predictions. These anomalies, observed by WMAP and Planck, challenge the isotropy and randomness expected from inflationary fluctuations, hinting at new physics.

>(1) DID YOU HEAR ABOUT X TALK ABOUT Y IT'S HAPPENING!!
Solution: Nothing ever happens
>(2) HOLY SHIT Z JUST HAPPENED WATCH IT ON A!!!!

>(4) IT'S OVER WE'RE DOOMED D IS HAPPENING!!!
Solution: Nothing ever happens
Applying this equation towards your life will make you happier since you will gradually stop focusing on things beyond your control to things that don't even happen in the first place. Every time some hysterical mouth foaming political, conspiratorial nut comes you babbling about some nonsensical "bombshells" (which are just nothingburgers in reality), remember to always apply the equation "nothing ever happens" and watch them go into a meltdown while you move on with your life and focus on things that are not only useful to your life but make you happier in the long run.
TLDR; Stop focusing on things beyond your control because nothing ever happens to begin with.

But there's a very fundamental dilemma: I think technological progress is a mistake. AI is a mistake. We should get blasted back to the stone age. How do I keep studying physics with such conflicting luddite thoughts? This genuinely bothers me and I often consider dropping out simply because I hate tech. Hell, I don't even own a smartphone.
I'm posting this because I trust that there's someone out there who is smarter than me and can easily solve this dilemma.
Everyone praises science and technology these days. We live glued to our glowing screens, we outsource our thinking to AI, and rely on apps to get our daily chores done. I claim that this "progress" is a net negative on human well-being, and all new tech is introduced to make the rich richer. Capitalism is the driving force behind technology: the need to replace workers with machines, the need to monitor citizens and harvest their data, the need to isolate people so they'd pay for Tinder...
This isn't what I signed up for. This is bullshit. For me, the marvels of technology would be things like the AC generator. It's truly amazing that we have lights and heating. That's good tech. But over time we went too far and now our latest inventions are literal doomsday machines. People are telling me I can't possibly claim that there's some acceptable amount of tech we should have, like I was Amish or something. That's exactly my claim. There's some very discrete point in time where tech stopped being beneficial and started benefiting from us instead.
It feels weird to study physics when I know it's no longer time for humanity to learn more science but to learn how to study its degenerative nature instead.
>uhh uhhh well akshually we made a bunch of bullshit up to scam the tax payers
OH NO NO NO SOIENCE SISTERS
The people doing this analysis claim that, if you plot precincts in a histogram by % of votes for a candidate, then you should get a normal distribution (or a "bell curve", as they call it) and any other distribution is evidence of voter fraud. I claim that there's no reason to assume that you should get a gaussian distribution and that the people doing this analysis are retards who suck at math and stats. who's right?

>1 universe age
Does it matter for galaxy formation how old the universe is past a certain #? Since this is a fictional universe, and the question of where this galaxy is relative to others will not be answered anytime soon, it shouldn't matter if the universe is 5bln years old or 10.
>galaxy star composition
This depends on the last question a bit. I want this fictional galaxy to be rife with younger stars that host life, but some stars also only come into being after long periods of time. Does the universe/galaxy need to be older/younger to ensure desirable stars are commonplace?
>galaxy size
I'm not worried about a large or small galaxy, since FTL is a needed trope to ensure the plot doesn't stagnate the moment people try and leave a star system. The issue is.....how big is a galaxy in width typically? Assuming light-years are used, not sure what the numbers end up being. I'm also not sure on the total number of stars in this galaxy, and if that also depends on galaxy age.
For context, I have OSA(~30 AHI), treatment resistant MDD, and TBI. Every treatment I've tried has failed; CPAP machine didn't help(currently trying to get a BiPAP), antidepressants, TMS, TRT, multivitamins, microdosing shrooms, blood tests dont show any deficiencies, etc. I take caffeine pills and smoke cigarettes just to barely stay awake through the day, but some days I just can't focus at all. I never have motivation; I have to force myself to do everything through pure willpower. I'm not fat, and working out isn't help.
My first time doing shrooms "cured" me for a few days but I went back down after smoking weed.

Why is this? I can't help but feel the reason there is no cure for baldness is because it is a male issue that does not affect women so people don't care. I bet if women were going bald they would be dumping trillions of dollars into finding a cure.

AI can now generate new materials given their desired qualities. So basically the vast majority of material scientists is useless now, only being relegated to the role of creating these materials and then performing tests on them, well at least until they make end to end robot operated lab where robots just move materials from machine to other machine and perform the tests themselves.

This stood in sharp contrast to my list of all-time favorite movies, drawn from a much larger/diverse field with incredible competition for the top spots. Yet, ranking my top 5 favorite movies of all time seemed, somehow, easier than ranking this much smaller set of movies. To make sure I wasn't crazy, I messaged my old English/Film Literature teacher to get his opinion on the matter. Now, he admitted that it had been some 60 years since he has seen a Shirley Temple movie, so I changed the prompt to this - "Which is harder - Ranking your top 5 favorite Martin Scorsese movies, or your top 5 favorite movies of all-time?" After deliberation, he replied stating that it was harder for him to pick his Top 5 favorite Martin Scorsese movies "by a hair".
So, I come to you lot. Is there some sort of mathematical principle to this paradox that I don't know the name for? Why is it harder to a ranked sorting of a smaller set than it is for a larger set?
My initial hypothesis is that it is akin to a field of wheat, wherein spotting the tallest stalks is easier when looking at the entire field as opposed to looking at a smaller section of the field where all the stalks are of height so similar that it becomes harder to differentiate them.
But is there a name for this principle already? I guess that's my question.
