🧵 Climate models can't predict the climate to the upside or to the downside.

There was a retard here, maybe a half year ago, who disagreed with me about this. My argument was that pockets of local climate change necessarily induce chaos into any prëexisting model.
The retard said no! No! I'm not a retard!
Now that the deprecation of carbon sinks proves me right, and proves you wrong—because you're fucking retarded—are you willing to come back here and admit you were ignorant and dumb?
Or will you keep pretending not to be both ignorant and dumb, and fucking uselessly retarded?

What is the most relevant factor to penis size? Yes I know it's genes but which genes in particular? I've heard that while the father contributes the Y chromosome, the mother actually has alot more control over what the penis ultimately looks like. So does the mother's genes play more of a role for this or is it pretty much just the father's?

Ok /sci/ it's time for another take on quantum gravity
Maybe you can help me reason if there's any merit, if it's actually just Mbranes and I'm too stupid, or highlight any other issues with it.
So here we go.
For starters, instead of trying to create particles for Gravity, we instead start with the fabric of spacetime and we attempt to generate quantum behaviour with it.
To do this, we suppose that at very small scales, the fabric of spacetime is warped, not simply as in the matter of gravity but with a significant number of rosenbridges (and more complex topological objects of some-dimensional space), into a veritable sea of foam - one that is constantly warping, folding and unfolding.
Identifying a singular location in the foam is difficult, because there are multiple noneuclidean paths that approach any given place, that the concept of location doesn't work unless you straighten out the spacetime. Determining a velocity is similarly difficult, and requires the spacetime to be straightened in a different manner.
From a broader perspective, any given position would bounce around in the perspective of one observing, though a sense of locality would be found in that it is more probable to observe a position near to where expected than afar - though the spacetime warping would permit it to appear near anywhere with nonlocality.
At larger scales however, these warpings of spacetime disappear with minimal effects of the folds extending past their immediate region, and general motion and position are preserved.

this still makes no sense to me.
time is a human convention. when you measure the difference between two clocks at a distance, you're measuring a difference induced on the physical clock by some mechanical force or another, you aren't measuring a difference in "time". there is no "time", there are only clocks and human minds to interpret them.
if it had any definition time would be an invariant, inaccessible, and eternal. it makes absolutely no sense to speak of time taking part in the universe, or of "spacetime".

Riddle me this, cosmologists. Inflation is described a second-order phase transition in Guth’s original paper. This means it needs a scalar field. The Higgs’ vev is too small to account for the inflation rate. Guth coped with this by saying there might be due to a GUT symmetry braking. This was of course before the simplest GUTs were ruled out by setting bounds on proton decay. So the million dollar question is: why is inflation universally accepted in the field if we have no evidence of that scalar field nor a satisfactory particle physics model to include it?

🧵 Best way to transcribe lectures?
Anonymous at Tue, 22 Oct 2024 09:47:44 UTC No. 16443874
Last week i started university and an older colleague (getting his second degree) suggested me to transcribe lectures. I'm trying to do it in the most low effort way possible, because i usually study on my notes so i don't really need the transcriptions.
What i do right now is:
-record the lecture
-get it transcribed by whisper AI
-Get it elaborated by chatGPT (corrects the errors that whisper does).
Whisper works quite well, but the last passage with chatGPT is a pain in the ass. It can't handle long prompts, so i have to divide the trascription in many samples, and the output is often wrong (it cuts out parts of the text even tough i specify to just correct errors and give me back the entire lenght of the text)
If you transcribe lectures too, please tell me your method. I'd like something more straight-forward on the elaboration of the text part. Ty.

Has anyone here ever heard of Synergetics?
No, I don't mean synergy. I mean the idea that all matter is comprised of Tetrahedrons (four sided pyramids).
https://en.wikipedia.org/wiki/Syner
This theory was postulated by Buckminster Fuller, the inventor of the Geodesic Dome, one of the strongest possible 3D structures still used by military today, as well as the concept of Tensegrity.
Tetrahedrons were chosen because of the idea at the time (and still today) that the smallest unit of matter is a sphere. However, if this were true, then the smallest possible alignment of four spheres of equal size would have to be the tetrahedron, making the entire universe fundamentally comprised of a matrix of tetrahedrons, even if the underlying geometry must be spherical.
Personally, I can't stop returning to this theory. It perfectly explains wave-particle duality.
Think of it, if you have two tetrahedrons spinning out of phase with one another, they will always collide at one of their faces or vertices. But if you have two tetrahedrons spinning in perfect phase with one another, then they can technically pass right "through" one another by sharing one face for the duration of one spin.
Think of it like me throwing a knife so that it spins while it flies. If you throw a knife at me with the exact same spin, then they will spin past each other and both hit their targets, even if thrown right at each other.

🧵 What is dark matter really?
Anonymous at Tue, 22 Oct 2024 05:45:46 UTC No. 16443668
Are the "fields" which material matter usually experiences really just dark matter which interacts with physical matter under a specific set of conditions? For instance magnetic field is measurable only when a particular charge is under some velocity, likewise an electromagnetic wave is only emitted when the said charge is undergoing some acceleration. An electric field is only observable when a dipole is present, and a gravitational field is only calculable when there's some mass to experience it and thereby prove its existence. In all instances, physical matter had to be in a specific set of conditions for the "field" to prove its existence, or more aptly, interact with the matter. Are those "fields" just different types of dark matter? Is there physical matter which is incapable of "stimulating" the dark matter in order to "prove" its existence? Is it plausible to start experimenting with random physical quantities just to see if we discover some new type of field, ultimately reaching closer to our understanding of what dark matter even is?

🗑️ 🧵 Nonlinear Nonlocal Analysis Problem
Anonymous at Tue, 22 Oct 2024 05:05:02 UTC No. 16443631
Is there a function [math] g: R -> R [\math] such that [math] g^2=g*g [\math], where * denotes convolution? We can take g to be integrable and bounded. This problem is hard because it’s both nonlinear and non-local. Obvious strategies all fail, with simple inequalities failing to rule out a solution and Fourier transforming getting you back to where you started.
Attempting to do power series or other forms of expansion end poorly because what is well behaved for the square term isn’t for the autoconvolution, and vice versa. Simple inequalities show that no such solution can exist which is supported on (1/e, infinity), even over the shared domain of [math] g^2 [\math] and [math] g*g [\math]. In general, no finite support works because the convolution will double it.
It’s worth noting that a solution to the problem can be horizontally rescaled to a solution for [math] g^2= c g*g [\math]. This isn’t the case if we define the problem over the domain (0,1) and take the convolution to be periodic (modulo 1). In that case, Jensen immediately rules out solutions to [math] g^2= c g*g [\math] unless c>1. Beyond that I have no idea. Another way to solve the problem would be to find a function who is its own Fourier transform, and whose square is its own Fourier transform as well. This is evidently difficult. Any new strategies would be greatly appreciated.
