Use Grok for your scientific endeavors, suggest it to your lab if they want to use AI. Grok unironically does focus a tiny bit harder on science than other AI's even if it sacrifices 1-2 programing points. 6T and 10T models coming soon if you feel it's currently subpar, will definitely be the best for at least a few months. Don't let Zionists rule the world, contribute to Grok and make it smarter. Any other AI achieving AGI first will create a permanent zionist world order until heat death.Honorable mentions Deepseek/Minimax for minor scientific inquiries, and respectable alignment.

>>16958169>in select cases/institutions you can have permanent research staff but not always.in most institutions that are explicitly "research institutes" you've got sorta-staff researchers. it doesn't line up exactly with the academic tenure track. how permanent these positions really are depends on funding though, how much of your research group funding is provided by the institution itself vs how much is external grants
>>16958177>As an undergrad who's in his 30's>What about joining a STEM related club?If you're currently in uni and want to work in a lab for a bit it should be very doable. You can just ask a professor if they have student projects available, or your uni might have e.g. program for summer projects. These are relatively low-stakes and low-commitment for all parties involved. Being in a real research group doing real research is quite different from labs done purely for learning or demonstration.Assuming you're the same guy who was interested in astrophysics, amateur astronomy is among the most lively amateur science branches. There very well might be a relevant club at your uni, and there definitely will be one in your country (probably even more locally).Getting a career in the lab is another matter.

Suppose a structure made of 255 cells. Is it possible to arrange them in such a way where each cell has a unique neighborhood? The first structure is efficient because each cell is unique. But the second and third ones has similar shapes which means some cells aren't efficient enough. (First Image)I think I worded it weird so. What's the least amount of squares, structures, or rectangular area you need to make all 256 shapes? (Third Image, the square with no neighbours can be excluded of course.)I managed to get 89 of them (Green Cells, Second Image. Actually 90 if you include the neighbourless cell) but I don't know if the minimum really is 256THE HELL ARE THESE CAPTCHAS YOU PEOPLE ARE INSANE
>>16957703Oh this is a neat question. Basically you are asking how to realize the most compact possible black and white bitmap where each of the 2^8 ways a pixel can be surrounded is realized exactly once? That sounds really tough. Like, I can wrap my head around 1D: suppose you wanna write a string of 1s and 0s such that every combination 111,110,011,010 occurs exactly once. It becomes immediately obvious that "010" can never be included in a string where all 1s touch. In your example, the neigborhood where all but the central pixel are white can never be part of the rest of the picture, so there can't be a "connected" solution.I suppose my 1D example would have this solution: "11101011". Then, all possible neighborhoods (4) are realized by a string of length 8 (or less, if I missed something).You could then ask "what is the maximum amount of neighborhoods you can get where all 1s are connected, and how long is the optimal string?" I suppose the answer would be "01110", meaning 3 neigborhoods and a length of 5. Your case seems like the 2D equivalent.
>>16957810"0111010" is more compact actually, so it is at most 7.
>>16957812Trying a proof:the solution would have to have at least four 1s to capture "111" and "010", which means it also must have at least 2 0s, meaning the ideal string is at least 6 and at most 7 long.You can just brute force all binary length 6 strings with exactly 4 1s and 2 0s which contain 111 as a substring: "001111", "010111", "011101", "011110", "100111", "101110", "111010", "111001", "111100". Those that don't miss 010 miss 110 or 011 instead.So 7 is the solution with the neighborless cell included.It also becomes clear that the number will vary widely even in 1D as you exclude select neighborhoods. So subsets of all possible neighboorhoods will give wild answers as a function of which ones.

Sweet, I can post my dunning Krueger slop here I hope? Apologies for the pure claudeslop AI psychosis writing, but maybe it has some merit or is at least entertaining as a theory.For complex systems, there is a unifying principle: the reliance on a massive, structured latent reserve. A small active subset with a large latent reserve. What do I mean? Well...Hibernating animals develop Alzheimer's-like brain tangles every time they enter torpor. Every time they wake up, the tangles fully reverse (Arendt et al. 2003, PNAS). The repair mechanism exists. It works. So why can't human brains do the same thing?The answer may lie in time. During hibernation, the brain is deeply offline for hours to days — no neural activity, no metabolic stress, no new damage. The repair system runs uninterrupted against a stationary target. Human sleep offers only milliseconds of local offline windows across a few hours. For a young, healthy brain, that's enough. For an aging brain accumulating damage faster than sleep can clear it, the nightly maintenance window is too short. The deficit compounds.But this raises a deeper question: what exactly is being repaired, and what is being damaged?
Most of your brain's synaptic capacity carries structured signals that no downstream circuit currently reads — not idle, not empty, but latent. We can see this structure mechanically in trained neural networks. When you apply a gravity simulation to a neural network's weight matrices — repeatedly shaking rows and measuring which ones settle into high-energy positions — a stark structure emerges: ~1% of rows carry most of the energy — they activate broadly and contribute to nearly every output. The remaining ~99% are specialists: structured, coherent, but activating only for specific inputs. They carry little average energy precisely because they're specialized, not because they're unimportant. Align them against an independently trained network and hundreds of dimensions match with significant similarity. The reserve is structured, convergent across models, and essential — just not broadly active. Sadtler et al. (2014, Nature) showed the same structure in biological brains directly: motor cortex learning is constrained to a low-dimensional subspace of existing neural activity. The brain adapts along pre-built paths, not from scratch.Your brain maintains this reserve constantly — routing around daily wear by reading from fresh latent capacity. This works as long as the maintenance system can tell reserve apart from waste.Alzheimer's corrupts that discrimination. Hong et al. (2016, Science) showed that amyloid-beta aberrantly activates complement tagging — the molecular system marking synapses for removal. Reserve synapses, carrying lower activity and weaker protective signals, get misclassified as waste and destroyed. Shi et al. (2017) proved the key insight: knocking out the complement tag in Alzheimer's mice preserved synapses and cognition even though plaques remained unchanged. The plaques aren't the damage. The mistagging is.
>>16958354>>16958353The destruction is silent. The functional core is untouched — clinical tests detect nothing. But the latent capacity is collapsing. Katzman et al. (1988) found this in human autopsies: individuals with higher brain weight and neuron counts remained cognitively normal despite full Alzheimer's pathology. Their reserve outlasted the corruption. Years later, when ordinary daily wear damages something in the functional core, the thin reconfiguration that would normally repair it reaches for reserve that's been destroyed. The damage becomes permanent. Then more accumulates. The trajectory — years of stability, then rapid decline — isn't the disease accelerating. It's a brain that lost its repair substrate, drowning in ordinary wear it can no longer fix.Sleep is when the heavy maintenance runs. Xie et al. (2013, Science) showed that during deep sleep, the spaces between neurons physically expand by 60%, flushing out metabolic waste including amyloid-beta — the molecule that corrupts the maintenance system. One night of missed sleep measurably increases amyloid in the human brain (Shokri-Kojori et al. 2018, PNAS).Which brings us back to hibernation. The repair mechanism that reverses tau tangles in ground squirrels isn't exotic biology — it's the same maintenance system human brains run during sleep, just given enough time. Lucey et al. (2023, Annals of Neurology) showed that just two nights of pharmacologically improved sleep reduced both amyloid and tau biomarkers in human subjects. The machinery works. It just needs a longer maintenance window than human sleep currently provides.
>>16958353>>16958354>>16958355This framework also reshapes how we understand learning. Learning isn't building new structure. It's thin reconfiguration — a minimal adjustment to which parts of the existing substrate get read. Modifying less than 1% of weight magnitude, touching ~32 independent directions out of thousands, produces massive functional improvement. The information was already there. The system just wasn't looking at it. This explains why children learn from single examples — evolutionary "pre-training" across millions of years embedded the statistical structure of reality into synaptic connectivity. A child seeing his first dog doesn't build a dog-detector. His visual cortex already contains latent dimensions encoding shape, movement, and animacy. He makes a thin reconfiguration: when these pre-existing patterns activate together, that's a dog.And the pattern extends beyond brains. Genomes show the same architecture. ~1.5% codes for proteins, ~98.5% is non-coding but conserved across species — a structured substrate that channels evolutionary change. Human and chimpanzee coding DNA is 98.8% identical. Nearly all the difference between species is regulatory — which parts of the shared substrate get read. A different species is a thin reconfiguration against a shared evolutionary reserve. Kirschner & Gerhart (2005) called this "facilitated variation": organisms are built so small regulatory changes produce coherent phenotypic shifts, because the substrate is already structured.

Immunosuppressants , or even better: JAC inhibitors. Neither JAC nor Antihistamines arrests development of further allergies. So if its permanent, because its Cladosporium or a common food allergen, or a pet....Then the only real option is hypo exposure therapy, like OITWhile you live in a cleaner environment. Get on the queue for OIT. Its not perfect, it takes about 3 months to reach the point of diminishing returns, then it takes about 3 years to year complete immune reset of said allergen.But you don't want to do it because of that, you want to do OIT or hypoIT because it also stops your cross allergies(pollen -> you also get a mild peanut/aloe vera allergy). You also want to perform hypoIT or OIT to ensure your next potential allergy do not develop. T. suffered with Cladosporium before getting it treated, leading to development of other fun allergies such as cat into cross allergy with mites.

>>16958196>When did you realize that the alleged “horrors of science” are based purely on lefty politics?All horrors are value judgements, and thus source themselves from either an individual’s or a society’s morality. Morality, while largely derived from the universal human experience, is subjective. Depending on how detached one’s morality is from the universal lived experience of mankind, one man’s horror can easily be another man’s nothingburger.

Math is the only thing that is real.Reality is just one giant 3D slide show that for whatever reason exhibit consistent geometric patterns from one slide to the next. Identifying and describing said reproducible geometric patterns in mathematical equations is what science does, and the only thing that is real.

More likely you are one-in-a-septillion chance than the other way around.Their reasoning is so flawed that if we manage to find one more intelligent life elsewhere, it would change absolutely nothing in their point of view. They would just say "well it happened twice instead of once, still doesnt mean its common everywhere", or "well NOW we know we are not alone, so intelligent life is easy to occur". But it still wouldn't make sense from their perspective because once or twice is basically the exact same probability considering the size and age of the universe.And all that without even considering non tangible stuff like dark forest theory, non human intelligent life, etcWhat causes successfull and otherwise smart high IQ academia individuals to be blind (stupid?) to such simple common sense and logic, what is this phenomenon?
