"/sci/ - Science & Math" is 4chan's board for the discussion of science and math.
60 years since the launch of Vostok-3 with Andriyan Nikolayev
Do X amount of particles in a TNT arrangement have more mass than X amount of particles in a hydrogen arrangement, ceteris paribus?
ANSWER.
Talk maths.
It is currently private and probably securely stored. However, the analysis features are limited.
>Would it be worthwhile to upload my genome to search for cancer markers/probabilities on open source databases?
>Is there a way to do it without compromising my privacy?
>Which databases do you recommend?
>What are the ramifications of genomic data being public? I only know of the golden state killer case, but I don't know if that should concern me, since I don't intend on doing a murder spree. If I did, I suppose I could just take precautions to leave other peoples' DNA at the crime scene.
The absolute gigachad John Carmack gives a 5hr stream of brilliant consciousness on all manner of topics, interspersed with Lex's inane interruptions and attempts to sound intelligent.
His takes on AGI are extremely compelling and make me feel like he might just be the guy. John predicts AGI before 2030 and he doesn't give a fuck what you think.

Absolutely worth a listen.
Explain to me why this is an axiom and not an objective truth. What kind of proof is there against these predicaments that mathematicians decided to call this an axiom instead of an objectively provable truth?
If narratives about the true nature of reality can be manufactured and consistently bought, what chance do we have as a species?

Do people move to these areas because they don't value science in the first place and something about these areas is attractive to this population, or is it that people live in these areas, and then something about the social environment in rural america makes people grow more antiscience over time? I.e. are antiscience folks attracted to rural areas, or do rural areas just make people more antiscience?
surch as Badwater Basin in Death Valley California, or Sevier Lake in Utah
becaus we are facing extrm high tempratuer, wild fire in California and Oregon,
lack of domestic water and farming water
I beleve in midwest America, the water cycle is short of millions cubic metre freash water
May be some people think desalination is enough to slove the problem
but human being a great desalination system --the mother nature!
we know desert contents great heat and wonderful evaporation rate
so all sea water factitiously fill into salt lakes
will become moisture into the atmosphere,then transfom to rainfall at other drainage basin system
and salt lakes surch as Badwater Basin didn't need to worry about salinization
In my rough estimate, get seawater from the coast,have to build more than 1000km elevated aqueduct
thats why I call this is a crazy idea,
BTW the final GOAL of this crazy idea is Fill The Great salt lakes with seawater
i searched through the internet for days, and there's indeed some methods to actually preserve my dna.But most of these methods can only keep my genes alive and my soul will just return back to the void i originates from, at that point i might just get a child or something.
But i know that if some of these preserving technologies actually advances and some laws changes, i might actually get a much longer life(cryonics can actually work if i am frozen alive and the technology is advanced enough to freeze my brain in a short period of time , actually)
So, what types of live preservation technologies actually work if provided enough technology advancements?
even Japan has world-class contributions in the post-war period
now let’s look at China. i know of only one good chinese physicist: Frank Yang who was actually basically american. and they’ve been “developed” for well over 15 years now. why are they so much slower than the USSR at actually accomplishing anything in physics?
hell they’ve been sending decades of PhD students to study in US departments (which Russia didn’t do) and yet still they have a really pathetic output in the field of physics.
why is that? is the chinese psyche just not the personality type for great physicists? or is their culture just toxic toward original thinkers of physics?
>therefore if I start being unable to sleep,yet experience 0 negative symptons of sleep deprivation,this would mean I have become/tapped into "the immortal timeline"

Two researchers in Europe have published this document which says that certain forms of humor should be criminalized because
>humour that is directed against ethnic and sexual minorities is deemed to inspire violent fantasies and eventually action
The paper is well referenced, however that conclusion has no reference to support it. Page 7 shows examples of the variety of humor which should be banned
>(1) The original iteration of the Wojak meme expressed emotions such as melancholy, regret or loneliness. It has gradually been adapted and advanced by far-right meme culture to portray liberals with blank expressions. The aim here is to show that “normies” do not question the information that comes from mainstream press and politics.
>(2) The Doge meme is one of the most famous internet memes, which has been adapted in various ways to tease a kind of outdated humour and style of individuals and politicians. In far-right circles, it has often been combined with Nazi memorabilia to trivialise violence by the SS and Wehrmacht.
>(3) The Pepe the Frog meme has been appropriated by far-right online activists. It symbolises “a kind of superior nonchalance toward others, helping to normalize hostile attitudes toward minorities and political opponents” as well as “a kind of anti-elite arrogance and condescension” (12). It has become the icon of the alt-right.
Which makes up the majority of the image content on /sci/. So scientifically speaking, is /sci/ doomed to be eventually banned from the internet for h8s peach? Is there anything we can do about our unfortunate fate?
Now, everything seems so piecemeal. Like you can only chip away at some subject so obscure that it is irrelevant to people, or only contribute a tiny amount to some meaningful effort.
I would love if someone could tell me "no, you aren't considering x field".
I'm slowly losing me sense of humor bros
It seems like the most ancient civilizations popped up in areas where cuisines are varied and are spicier, in the sense of using more spices, than others. This implies fertile lands, sure, but Western and Central Europe are all fertile, and no civilization popped up there until thousands of years of harsh selection, another route for forming larger groups but also intelligence, which ended up with a unique form of civilizations to come about.
Something similar in Africa. Subsaharan African societies didn't form civilizations at all.
Their cuisine is relatively simple, and it seems the pattern holds true there as well. Ethiopia had stronger kingdoms and larger organized societies than the rest of Subsaharan Africa, and they have a decently varied cuisine.
Now, there is a chicken and egg problem. Do smarter societies create more varied cuisines? Or does daily diet affect a society's organizational ability, and thus indirectly intelligence, by maximizing potential cognitive abilities?
Since ancient civilizations, like the Indus valley, had access to a more varied set of ingredients, this increases the number of nutrients they have access to.
Intricate cuisines are not the same as varied cuisines. Japan only had access to a limited set of ingredients compared to other regions, but their constant infighting for thousands of years potentially had a similar effect as was seen in Europe. Makes the Germans and the Japanese share something in common.
Ultimately, I think there is something in there. A factor of many for the appearance of larger forms of organized society.
>society is full of dumb normies that have low intelligence and no empathy, but they virtue signal all day
>normies hate non-normies
>psychopaths use normies to maximize personal gain
>if you aren't a normie, normies will try to force you to conform
>normies will shame you, isolate you, even abuse you physically, emotionally, financially, etc.
>you have drives that turn you into an NPC (sex drive, etc.)
>psychopathy is a way to abuse the virtue signalling system and enslave normies to maximize personal gain
>psychopathy lets you turn normies into cattle
>psychopathy lets you destroy your sex drive and enslave normies, enacting revenge on the normie filth on the behalf of every tortured genius in the history of humanity
>psychopathy lets you make normies (normalfags, NPC, goyim) work for you, while you do whatever the fuck you want with your life and free time
The alternative is to accept the stupid "social contract" and work for 40 years, surrounded by goy normalfags, for psychopaths that use your hard work to finance their degenerate activities, e.g. prostitutes, cocaine, etc.
To highlight how stupid normalfags are, they all say stupid shit like:
>you can't do X! because if we all did X, then everything would be Le Bad
this is stupid. If I do X, then my decision will not affect the decision making of any other person. If I throw garbage on the street, I will not instantly pollute the entire planet.
>brooo you have to die in Le Goy War to be a hero!!! bro you have to work for 50 years at mcdonald's!11!1!! brooo you have to pay taxes
these arguments are fueled by stupidity. These stupid, subhuman goyim don't understand that wars are fought for the interests of the elites, corporations are a way to abuse normies by using them as cattle and taking their collective man hours and turning them into lucrative products and services.

because what's disorderly is just what these people say.
If the very existence of specific diagnoses is in question (see CPTSD), or it's essentially impossible to find a single feature that consistently characterises a certain diagnosis (see ASD), you have more than a problem with "the finer theory". There are fundamental categorisation problems at work here.
The DSM acknowledges this in its very last section where there has been a proposal for a very long time to characterise conditions by scoring them along a set of fundamental axes or principal components. While we appear to be nowhere near a consensus on what those components should be, this will almost certainly be a better approach than the wordy, subjective criteria that currently form the basis of modern psychopathology/psychiatry.
which is that majority behaviour seems to prescriptively determine minority "dysfunction" by virtue of simple comparison. Psychological function is impossible to divorce from social context, and this is not a new observation. A large subset of "neurodivergent" people such as those with high functioning ASD or ADHD are vocal proponents of this. They posit that much of the dysfunction or social distress comes not from some inherent lack of capability but just a general impedance mismatch with neurotypicals. Those with ASD often report much fewer problems empathising and interacting with other ASD persons, for instance. It's reasonable to ask: If they were the majority, would ASD still be a disorder?

What is the official /sci/ explanation for this? Are our estimations for the age of the universe wrong? Perhaps just galactic formation occurs differently?
It makes my mind sharper and more productive than anyone else I know of.
It suppresses my impulsivity and my invasive internal monologue that did nothing more than bring chaos in my life.
It is the de facto thinking white man's drug, it just turns me into a superior person.
You faggots say this thing is a bad habit - ironic considering browsing this cesspool of a website is clearly one of the worst habits I have.
Why should I ditch it when it helps me in mogging the shit out of everyone else?
Please no "two more weeks" replies, it did more miracles than harm on me as of now.
Extreme heatwaves breaking temperature records, more floods than ever recorded, and more forests being burned down in history were all attributed to the Earth spinning faster.
Also what scope of math is the most useful for this?
Always hear about those quants on wallstreet being wizards creating new models to beat the market(maybe why they are paid millions)?

Know math, know some physics, can code.
I'm a bit worried that they're only doing two unmanned missions and then the third one will be both the first crewed flight and the first to land.
If you compare it to all of the preparations and missions NASA did before Apollo 11 it almost seems rushed.
I thought about having the user put the cloth against a diffuse spectroscopy sensor, the device would then read the values and compare against signatures stored in its memory to make the classification.
I have two questions:
1. Would this work at all? Would there be enough differences in the spectrum (e.g: cotton vs synthetic) as to offer a reliable output?
2. Any idea where could I purchase such a sensor? It would be preferred if the output could be handled by a microcontroller or a PLC as raw data instead of a PC. Price is also a conditioning factor, the cheaper the better.
The other option would be analyze different samples and purchase LEDs and sensors with the most caracteristic wavelenghts reflected off each sample. That would certainly result in a cheaper system, at the cost of flexibility.

How has this not been done? Whoever solves it will become an instant billionaire. The financial incentive is there. It does not seem particularly difficult.

anecdote: one day i walked into the office of one professor at my US university and he was reading TRF. i had to contain myself because internally i was ROTFL
his blog was great, at least for physics posts. we need him to come back.
if anyone agrees with me we should start an open letter to ask him to come back. he seems to be active still on disqus and to a lesser extent on wikipedia. who is with me on asking him to come back?
What the fuck is this idiot talking about? Of course the formal system with only the identity axioms is consistent, and it's easy to prove this without ever using ANY metatheory. The notion that every proof has a well-defined metatheory is just retarded nonsense. Just look at the many proofs of the identity 1+2+3+..+n = n(n+1)/2. What metatheory do they have? Clearly that's a nonsensical question, since the proofs usually rely on common sense and rational thought, rather than PA, PRA, or any such formal system. This is evidenced that the proofs are given by pictures and equations rather than fricking statements and proof tries in first order logic.
How can someone be so retarded as to make statements in pic related? Have they never actually studied math?
>But in statistical mechanics things become more complicated.
>The second law of thermodynamics, as it arises in statistical mechanics, merely states that it is overwhelmingly likely that net entropy will increase, but it is not an absolute law.
So, statistically speaking, there is a non-zero chance that, spontaneously, one side of a box will heat up and the other side will cool down? Kind of like how you can walk through walls with quantum tunneling.

If taking stimulants like candy makes people the better workers grifters crave so much, why isn't it approved of? They WANT more productive workers. They WANT hyper-focused people. They WANT you to work yourself to the bone. They WANT your work ethic. And yet to consume stimulants to implement their work ethic into reality offends them. Why?
Experts have recently discovered that rain water (much like garden soil) is highly toxic, and that it contains high levels of cancer causing forever chemicals. Nevertheless, anti-science types who are obsessed with doing things "naturally" often rely on rain water for things like gardening, or even drinking water and bathing. This is especially common amongst organic farmers, homesteaders, and people who are supposedly living "sustainably" or "off the grid". Unfortunately, we are now learning that collecting and consuming water in this manner can cause cancer, and can even be deadly, because of all of the forever chemicals in the rain water.
That being said, why do people always assume that natural=better? Also, scientifically speaking what is the safest and best water to drink? Obviously stuff like well water, spring water, or rain water is off the table, since water from any of those sources is likely to have extremely high levels of environmental pollutants. I guess the really question is, what's better municipal tap water, or bottled and filtered water?
found it on the ground he let me pick him up.
hes panting alot and has his head tilted to the side about 30degrees left and down.
he flapped around with both his wings and kicked with both feet so it seems his not in pain and seems to have no broken bones?(ribs maybe?). i placed him in shallow cool water on my balcony. should i do something else?
I have yet to find an explanation of this despite reading a lot on the topic and doing my undergrad degree in neuroscience. There are always appeals to the tremendous complexity of the brain, but how is it exactly that complexity is supposed to generate first person perspective?
To be sure, information theoretic approaches and neuroscience explain pretty well how vision can be processed, how behaviors that mimic self-awareness could arise, etc. These theories normally center on a global workspace for consciousness and a "theory of mind center," that evolved to increase our social aptitude, which simulates what it is like to have other experiences. However, none of this gets at home first person perspective actually arises.
Complexity itself is notoriously nebulously defined. In Tegmark's book, he posits that consciousness arises as a function of complexity and information content (he also slides in some panpsychism without much comment). But then information appears to be defined nebulously as semantic meaning, which is begging the question.
3,000 kilos of hydrogen gas in a vat exhibits complexity. Gas laws are emergent phenomena resulting from countless relationships between molecules, which are constantly sharing information with each other. Arguably, gasses are less complex because they are too networked. Information content wise, mapping the phase space of a large volume gas takes up more information than mapping the phase space of a human brain. So if complexity and information content alone cause consciousness, galaxies should be conscious.

According Donald Templer (2006), IQ and skin brightness correlates at 0.92, a near perfect correlation.
Rushton found that in both human and non-human animals, darker pigmentation is associated with higher levels of aggression and sexuality, as well as lower intelligence. (https://cyberleninka.org/article/n/1102634)
According to a Scottish baron named Michael Anthony Woodley of Menie, blonde hair is correlated with higher intelligence and higher social status.
Non-whites such as Finns and Koreans have lighter skin than whites. Also, Finns are the most blonde and blue eyes race on earth.
White people are dark and swarthy, so they have low intelligence and higher criminality than non-whites like Koreans and Finns. Koreans have an average IQ of 107, Finns 104 and Whites 99.

I remember the following information:
- It was quite long -> I believe at least 40 minutes or something up to an hour or multiple hours
- It was American -> The guy explaining everything referenced the SATs at the start I think and had an American accent
- It had relatively good production value with humour, I vaguely remember it featuring slides with jokes and good visualisations it wasn't quite so dry and made the experience more enjoyable
- The guy doing the talking sounded young
- I remember the video beginning with some extensive definitions, I especially remember it discussing monotonic functions, limits and continuity in functions
Any help is greatly appreciated. Also feel free to discuss other resources relating to calculus that may be helpful. Thank you in advance.
We need something like a Pol Pot brutally purging the entire field so that it can all be rebuilt from ground zero.

I want to figure out the secret to immortality, and give myself superpowers like spider webbing or stopping time. I also want to figure out gene editing so I can make myself look even more like a God than i am now.
I'll be starting my science journey with mathematics, but do you guys think it's possible for one viciously focused man to accomplish such a thing? If he is one of the smartest and most special people to ever live?
"Biology" isn't an answer because I want to know WHY biology is better, not HOW to tell who's a boy or girl
More importantly, what are some good books to read about this? I'm an aspiring BME student and would like to someday make a set of picrel on my own. Something like a roadmap of books would be very nice
The only classes where I felt challenged were the compsci and math classes. I wrote my final paper for the diversity class 45 minutes before it was due and got 100%, and I'm a pretty bad writer. High school was harder, for god's sake. I'm not against the humanities, but Christ, these classes feel like they're dumbed down and meant solely to make pretentious rich kids feel like they're some sort of second T. S. Elliot because they know what phatic communication is, or because they can describe Kantian ethics. Maybe I'm just too stembrained.

2. Arithmetic statements are exactly those which have empirical meaning and can be described as statements of prediction about processes in the real world (with the caveat of idealizing an unlimited (but not necessarily infinite) amount of memory.
3. Other statements in mathematics are only meaningful in as far as they are equivalent or relate to arithmetic statements (e.g. the Riemann hypothesis may be restated as the conjecture that the algorithm in pic related does not halt)
4. The consistency of modern infinitistic mathematics (ZF) has not been proven. That means it's entirely possible that someone in a 100 years will show that this whole framework of infinite sets is nonsense. No good reason for its consistency has been given.
5. Set theorists have discovered many very simple and natural propositions, most notable CH (as opposed to Godel sentences in arithmetic, which would take centuries to write down) in set theory whose truth is independent of the current framework ZFC.
6. No programs have been successful to resolve cardinality of the continuum question by giving convincing reasons why one rather than other cardinality should be chosen. This demonstrates radical independence in even the simplest questions in set theory.
Why is my nigga Pavlov so criminally underrated?
One problem that could be considered the hardest math problem in the world is the Riemann hypothesis. This is a conjecture in mathematics that has yet to be proven. It states that every non-zero whole number is the sum of a certain sequence of prime numbers. Many mathematicians have tried to prove this hypothesis, but so far, no one has been successful.
Another problem that could be considered the hardest math problem in the world is the P versus NP problem. This is a problem in computer science that asks whether every problem that can be solved by using polynomial time algorithms can also be solved by using an algorithm that runs in polynomial time, but with a much smaller number of steps. This problem is still unresolved and continues to stump mathematicians and computer scientists alike.
