The qaratic was deemed impossible to solve until the 16th century and this jewish galois chud allegedly says this image right here is not possible to solve.
>>16870379Jargon is necessary in fields that matter. Mathematicians take it to another level. There was a quarter math magazine published where the cover was written by some well known faggot. A fields medalist who won the fields medal in the same sub discipline the cover writer was in wrote a strongly worded letter to the editor. In that letter he explained he was a fields medalist, an expert in the same topic as the covers author and had no fucking clue what that author was babbling about since it was encoded in idiosyncratic jargon. Mathfags in particular love to encroach their schizophrenia into incomprehensible jargon. Go ahead, I dare you to try defending this story.

Why can't we fucking think of anything better?

>>16859425Because you can have desalinated seawater as a byproduct that helps with water shortages retard.There is no better way. This is the best and most useful. We don't need another way.
With DT fusion over 80% of the energy is carried by uncharged neutrons which need to be stopped by radiation shielding... so all that energy pretty much has to end up as heat.If water feels too low-tek you could use helium or CO2 as a working fluid but power companies don't care how cool the working fluid is.

Why do humans kiss?

>>16867056Our lips used to be like an extra hand back when we had giant chimp lips. If you ever watch a chimp try to use tools, he/she will 100% if the time use them to hold and manipulate objects.So its like a handshake, not sexual (except contextually). In most cultures that have existed, it wasn't explicitly sexual, just a greeting.

>>16870526how promising is thhis research?>Here’s the translation of the provided content into English:---New Research on Nerve Injury Repair Is Here!Hey everyone, today I want to share a super impressive research finding! Schwann cells play a crucial role in repairing long-gap peripheral nerve injury (PNI)—their migration, proliferation, and secretion behaviors are really important. And bioactive ceramics can release active ions to regulate these "repair" cells.Researchers Wang Lin and Wang Zheng from Huazhong University of Science and Technology, along with Chang Jiang from the Chinese Academy of Sciences, discovered that the bioceramic akermanite (AT) can enhance the proliferation, migration, and secretion of Schwann cells by activating the PI3K/AKT and MAPK/ERK signaling pathways. When combined with silk sericin (SS), the effect is even better—they synergistically enhance the pro-regenerative behavior of Schwann cells and accelerate axon elongation.The AT-SS composite conduit they developed showed excellent performance in restoring the structure and function of a 13mm transected PNI. Compared with commercially available ePTFE conduits, it promotes axon and myelin regeneration, improves nerve conduction, and alleviates gastrocnemius muscle atrophy. Moreover, its functional recovery effect is comparable to that of autografts!The related findings were published in the paper titled "Bioactive Silk Sericin/Bioceramic Nerve Guidance Conduit for Effective Repair of Long-Gap Transected Peripheral Nerve Injury through Regulating Schwann Cells," in the journal Advanced Science (Impact Factor: 14.1), with a publication date of July 2025.

You get the same sort of pattern from plotting [math]\sin(x^2 + y^2)[/math], which is sometimes used as a cool demonstration of aliasing.https://hsvmovies.com/static_subpages/personal_orig/math/aliasing/index.htmlhttps://cs.uwaterloo.ca/~csk/other/alias/But OP's version seems a bit easier to analyze. We have triangle(x+a) = triangle(x) + ax + triangle(a), so the pattern close to (a,b) is the ring pattern near (0,0) plus ax+by plus a constant. When a and b are integer multiples of the modulus n, the ax+by part vanishes with the mod n step. When a and b are each close to multiples of [math]\frac{n}{k}[/math] with k some integer greater than 1, the ax+by part doesn't vanish, but it adds multiples of [math]\frac{n}{k}[/math]. And when you average a set of pixels with values [math](0 \frac{n}{k} + c) \bmod n, (1 \frac{n}{k} + c) \bmod n, ..., ((k - 1) \frac{n}{k} + c) \bmod n[/math], you get [math]\frac{n}{2} - \frac{n}{2k} + (c \bmod \frac{n}{k})[/math], so you can still see the ring pattern through it, but more faintly.

That we will never possibly be able to know the truth about the origin of our universe? Just think about it, for any subgroup, you cant possibly use the properties and objects into this subgroup to explain the properties and objects corresponding to the parent group, it is just not possible.
>>16868654Godel only showed that, in order to show something is true, in addition to defining the thing itself, you must include some set of instructions for decoding the definition of the thing, which cannot be part of the definition of thing itself. Thus, every systemic model requires some information to exist that is outside of it in order to define itself completely, otherwise, it can only give an incomplete description. This is because, even if a model contains all the information we need it to contain, we won't know how to make heads or tails of any of it if all we have is the model and nothing providing the context we need so we can understand it.People that think godel showed math is incomplete or some shit are either trolling, retarded, or both.
>>16870237>Even when such a limit doesn’t exist in terms of rationalsBut every term in the sequence is a rational number. If we have some preconceived notion about what a number ought to be, mathematics is not about that. We had a preconceived notion about what triangles were but then Lobachevski, Riemann, Einstein showed that mathematics or even physics don't abhor formal deviations from that prejudice about triangles, just like Torricelli showed that "nature" doesn't really abhors atmospheric vacuum like some ancient greeks believed. Being uncomfortable about calling some set of entities "numbers" is legitimate, like Descartes being uncomfortable with complex numbers. But the heart of matter is that mathematicians study these entities wether they are really (or should we really call them) numbers or not.>It’s a circular definition. Limit doesn’t exist? No problem, let the sequence itself fill the gap of a real.There is not an absolute definition of a what a limit (convergence) should mean either. The limits you are talking about involve the euclidean norm, but there is a notion of limit where every relevant sequence converges (every limit exists in Q), and some other notions like ultrametric and p-adic norms. This plurality shows that we study real numbers as a logical possibility more than as a logical necessity.
>>16870303>This plurality shows that we study real numbers as a logical possibility more than as a logical necessity.History says otherwise. We study real numbers because engineers and physicists, after Fourier shot a bazooka at what was known of the calculus of functions, were able to produce concrete results with Fourier analysis despite objections from every mathematician at the time. We’re really studying real numbers because engineers and physicists left us no choice, otherwise how would we explain the real life results they’re able to make?
>>16870312I wouldn't use that line of argument against Wildberger objections. Did he ever disagree with the usefulness of Fourier analysis? And the gist of your post is that mathematicians ended up studying real numbers out of historical and practical, maybe even epistemological necessities. But that doens't mean logical necessity. Similar thing happened historically with first-order logic, but nowadays logicians talk about logical anti-exceptionalism. That's what i mean about logical possibility instead of necessity.

As bad as asbestos, even? Damaging to the DNA level?
>>16868734>Are LEDs Bad For You?Yes>As bad as asbestos, even?No, asbestos is worse.>Damaging to the DNA level?I doubt it. If you mean damaging in the sense of frying cells like a microwave, I would say no. It may be potentially possible in the realm of influencing gene expression, but I am not an expert on that topic. If there were convincing evidence, I'd peruse it. But I wouldn't panic over it either. All said, LEDs are unpleasant, poor sources of light that do not reproduce color accurately, and this can affect mood negatively, which can affect other bodily processes in difficult to determine ways, some of which we may not fully understand yet. Stress and mood should never be discounted as major sources of health concerns. They can cause dramatic physiological responses.
>>16869696People in the X thread claim than the temperature of you LED doesn't change much. They give no evidence, though. Maybe they are right. What's sure, is that they do a poor job at being convincing. Light therapy is a real thing, so perhaps there is an antagonist to it too.
>>16869696>>16869792The "temperature" of a light (its overall color tone, e.g. "pure white", "cool blue", "warm orange") is separate from its ability to accurately reproduce the spectrum. It doesn't really matter in the end, what matters is whether the light can accurately reproduce individual colors within the spectrum, and LEDs are inferior (fluorescents are worse, but LEDs are still lacking).You can have an LED white light and an incandescent white light of the same brightness and shine both at a white wall, and both may look exactly the same. The problem starts with reproducing the colors of all the objects in our environment. The "white" that is sunlight contains the entirety of the visible spectrum (because that's what we evolved to perceive). But artificial light contains fewer wavelengths mixed together. This can still look "white" (or bluish, or orangeish, depending on what "temperature" you buy), but objects will look visibly different under artificial lighting because the correct wavelengths of light for them to appear natural simply aren't being emitted by the source.You may have seen images like this and thought they were just marketing gobbledygook cooked up to sell products, but it's not. It's a real visible effect. And constantly living under these lights make everything look wrong, dull, and sickly, and it influences mood.
post the paper
>>16870381>simply aren't being emitted by the source*or are being emitted in incorrect ratios, with some wavelengths overemphasized to compensate for less intense ones, resulting in the visible "wrongness" of object colors.Incandescent lightbulbs do not reproduce the exact spectrum of sunlight, but they produce a much more linear gradient than LEDs and fluorescents, resulting in a form of light that, while visibly not identical to sunlight, is not as displeasing as artificials.
