Full Genome Sequence
flettnersails
Recently got my full genome sequenced by George Church's company (nebula).
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.

ITS UP! Actually, it was up a week ago, but can't find any threads in the archive about it.

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.

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?

Why Being Anti-Science Is Now Part Of Many Rural Americans’ Identity _ FiveThirtyEight
Why does geography have such a big impact on the statistics, demographics, and popular opinion? Why do rural areas tend not to value science and truth?

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?

Fill salt lakes with seawater
oasis-1024x768
I am writing to ask the feasibility of My crazy idea:Fill salt lakes with seawater
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

which ways of cheating death through science actually works?
Cryogenically-Freezing-Human-Body
i recently knew that death means lost of my consciousness and soul, with no ways to redeem it, and i am very afraid.
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?

is china just bad at physics? if so why?
C173DEF6-DBCD-4598-8536-7937836C6298
thinking about the history of physics, it strikes me that Western Europe was originally on top, then after WWII the US quickly rose to the top (incorporating their half of Europe) and the USSR (incorporating the other half of europe) was very competitive and even better in some fields of physics. Russia was nearly on par with the West within a few years of the end of the war in terms of nuclear physics and by the 60s they had an amazing physics culture. that’s like 15 years since the end of WW2, they were already world-class

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?

https://home-affairs.ec.europa.eu/networks/radicalisation-awareness-network-ran/publications/far-right-extremists-use-humour-2021_en

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?

Idk if this is sci, but is there a correlation between ancient civilization and cuisine?

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.

Is psychopathy/sociopathy the peak of human development?
>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.

I watched a youtube video were this critic of psychology referenced this as an example of how weak of a science psych really is. At first I thought he was joking "a child not listening the principal" is somehow a disorder if it happens rnough according to
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?

Spectroscopy questions
41598_2020_79517_Fig2_HTML
Hi /sci/. I'm working on a device to help people classify garments by their fabric's composition so they can be properly recycled.
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.

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?

math pants
Mathematically, a pair of pants has 3 holes. But that definition is based on a surface of zero thickness. In the real world, a pair of pants has a boundary of, presumably, nonzero thickness, and so this must be equivalent to a solid 2-torus, right?

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?

If the earth is mostly water, why would the most intelligent species be on land of all places? wouldn't the more dominate species be in the oceans? Land is very limiting and forces us to build and use all these needless technologies to survive, but the ocean is so vast it provides everything, not saying a water species wouldn't develop forms of tech but it wouldn't be near as much as we have to do on land. Was coming on land a psyop for ancient species?

Cancer Causing Forever Chemicals in Rainwater
Rainwater everywhere in world 'unsafe to drink' due to cancer chemicals
Why do anti-science conservatives and even some new agers always assume that natural=better? This is a complete logical fallacy, since there are many "natural" things that are dangerous (e.g. mercury or arsenic).

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?

Is-the-hard-problem-really-hard
For folks who think we basically understand how consciousness works, what is the mechanism that creates subjective first person experience?

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.

Skin colour and Intelligence
Anna-Sofia Ali-Sisto1
According to Peter Frost, a Canadian scientist, those with higher social status have lighter skin, lighter eyes, and lighter hair because men with higher social status historically married women with lighter skin, lighter hair and lighter eyes because men find women with lighter features more attractive. On the other hand, men with lower status bred with women with darker features.

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.

Searching for Extensive Calc Vid
Screen Shot 2022-08-10 at 11.11.55
Hi all. Earlier this year, I found an extensive and quite satisfactory video on here that explained certain concepts of calculus quite well. Unfortunately I can no longer find it nor where I bookmarked it. I am wondering if any of you would be able to help me in rediscovering it.

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.

riemann hypothesiss
1. Modern mathematics crucially relies on the concept of infinite sets, which is empirically and computationally meaningless.
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.

Hardest math problem in the world.
DOG FGAZUYHNGIDUOIWXEHI
There is no definitive answer to this question as it depends on the individual's level of mathematical ability. Some people might find an algebraic equation or calculus problem to be the most difficult, while others might find a simple arithmetic problem to be the most difficult. Ultimately, it is up to the individual to determine which math problem is the most difficult for them.

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.
