What’s cool about Everett’s interpretation? The logical conclusion (no matter how much some people deny it) is that we’re going to end up in infinite misery in our own lonely universes until the heat death of the universe.

The mainstream theory of heat transfer says there are three mechanisms: Convection, Conduction and Radiation. How can people actually believe this Afghan blankets exist. Air circulates freely through the giant holes (convection), and energy is free to go through them as well (radiation). Hence it only insulates against conductive head transfer, which is the smallest component if you're not touching anything. Yet Afghan blankets are incredibly warm.

The "heat equation" is based on faulty premises, it should be thought of in terms of "warmness" as a property of objects. Afghan blankets are warm because the material they are made of (wool) contains a large amount of warmness. Other fabrics are warm to varying degrees. Sunlight contains warmness. Spicy foods as well. The opposite of warmness is water. Water cancels the warmness of a wet blanket. The warmness of a sunbeam destroys water. Although fire creates warmness and is destroyed by water, it does not appear to consist of warmness .

This is a work in progress. Please feel free to contribute.

I don't know if they connect it to the "warm-ness" of blankets, but in China there's a very well-developed theory of food and disease along the lines you outlined. Basically all Chinese people follow it. From Wikipedia...
>Like medicinal drugs, food items are classified as "heaty"[citation needed] (?; ?; rè) or "cooling" (?; ?; liáng).[26] In popular understanding, "heaty" or "heatiness"[27] food is typically "high-calorie, subjected to high heat in cooking, spicy or bitter, or 'hot' in color (red, orange)", and includes red meat, innards, baked and deep-fried goods, and alcohol.[24] They are to be avoided in the summer and can be used to treat "cold" illnesses like excessive pallor, watery feces, fatigue, chills, and low body temperature caused by a number of possible causes, including anemia. Green vegetables are the most typical "cooling" or "cold" food, which is "low-calorie, watery, soothing or sour in taste, or 'cool' in color (whitish, green)". They are recommended for "hot" conditions: rashes, dryness or redness of skin, heartburns, and other "symptoms similar to those of a burn", but also sore throat, swollen gums, and constipation.[24]

You should look into humor theory. You had to carefully arrange the order you ate different types of food in, so that you wouldn't cause a humor imbalance as your humors were sensitive to temperature. This is the origin of the X-Course-Meal, why you start with warm soup, eat a cool salad, some dry bread, your warm meal, and then your cold desert in precisely that order.

A lot of people claim that this could do more damage than goods but most of those studies use low yield, old nukes as a basis.

We stopped making nukes bigger and bigger because its cheap and makes more sense to make multiple average sized nukes to use in war. We haven't even come close to a fraction of the limit of destructive power a single nuclear device could hold.

The U.S. had plans to build a 10 gigaton bomb during the cold war which still, isn't even close to the ceiling.

Anyway if this is a point about the CS meme then yes, science is dead in the sense that everyone believes data can solve everything and anything. It's become the end, rather than the means to an end. Rather than viewing data as a tool to be used to create other tools the data itself is manipulated and allowed to draw upon itself. It's the same problem large companies have with focus testing and design-by-committee: after a point only certain datasets are allowed because they reinforce what the organization wants, not what it needs.

People have become aware of this on the left with algorithmic bail adjustment systems being "racist" and people on the right have become aware of it as data-driven advertisement no longer promotes products they want to buy. It's probably an unsustainable death spiral down until the system collapses due to outside pressure - the economy itself falling to bits due to covid.

No one is expecting you to be amazing our the gate. The expected training time for an undergrad is ~1 year from beginning of training until they are able to independently plan and perform experiments.

Try to learn the theory behind why you are doing certain experiments and not others to address the hypothesis. Identify the advantages and shortcomings of each so that you can better troubleshoot/plan out experiments independently. Also try to read a modern review or two on your research topic to get a better handle on the groundwork. Ask your direct mentor for more in depth work that is directly being built on.

In short, try to be enthusiastic and don't get discouraged when things may not go as planned. Enjoy the process of learning and discovery. We can tell if you want to be there or are just going through the motions and we would much rather have a person who is enthusiastic then a stick in the mud.

I did undergrad research in experimental physics. It's always either something very simple and tedious or a coding project. I did the latter because my prof didn't know C++, only Fortran.
Theorists almost never hire undergrads btw because you're considered an unreliable dummy to them.
Undergrad research only exists to increase your chances of getting into grad school because academia today is overwhelmed with applicants thanks to student loans.

How do I scientifically proceed if I'm less intelligent than the average pwrson and might have a low IQ?

>> No.11979481

I have a high IQ. One thing I recommend to everyone is to read scientific material slowly. I am a slow reader in general because I vocalize but I read technical material very slowly. I like to make sure I understand each sentence before I go to the next one. Even smart people sometimes like to skin technical material. I hate that and I never do it unless I'm just looking for a formula or something. If you want to understand something, read it slowly! If you didn't understand a sentence, don't go to the next one. Go to the earlier one. Sometimes this is a pain in the ass because the author of whatever you're reading didn't write to be read that way, but reading carefully and slowly is basically my best advice for anyone who wants to proceed in science.

Literally though I have a very high IQ and I read slow as fuck.

Anytime discussion about the start of the universe comes up, the answer is pretty much always just "big bang". But that doesn't answer the more interesting questions of why did the big bang even occur and where did the matter come from? Why did all this matter exist in a tiny point before it expanded? It can't have just always been there, that is a non-answer. There must have been a state where no matter existed in our reality. Even if the singularity's mass was so great that time itself was not moving, it still does not explain the presence of mass to begin with.

Are there any leading theories that explain this? Simulation?

well ok. every physicist admits that the big bang is a “problem”. most astrophysicists just go ahead and ignore the “problem” since it doesn’t bother them.

most string theorists say “eventually we will have the final theory and it will resolve things but for now *shrug*”

but i think string gas cosmology is onto something. maybe it isn’t totally correct but it is a great idea that should provdxe a framework for future research. however. brandenberger left his ivy league tenured position and moved

Quantum mechanics literally "magics" thing into existence constantly but on time scales so small that you cant measure it.
90% of the mass of a proton comes from virtual particles popping in and out of existence.
Like it or not, this is the way it is and quantum mechanics is responsible for the best predictions in all of science. It's the most reliable technology we have.

Hey /sci/, I have an incredibly obscure question for you. Any information you can give me or anything that would lead in the right direction would be appreciated. What have you heard about the drug Clonodine and its effects on children? Through my personal experiences which I can't elaborate on for the sake of my safety, I believe that children in mental hospitals in Florida at the very least are being administered Clonodine without their or their parents knowledge or consent. Again, any info, leads, anecdotes, or information you can give me about this odd substance would be greatly appreciate. You all are absolute lads, and I wish you well.

hi pharmacy student here. if theres any "psychoactive" drug you want it clonidine. This drug is actually an antihypertensive with sedative properties. It works by blocking alpha-2 adrenaline receptors. other true psychoactive drugs have tons of side effects . so if u want to take a sedative i would start with clonidine first since its very safe

>odd substance
They’ve been administering atypical antipsychotics to children and adults for years. We used to play seroquel Monopoly when I was admitted into one. It’s a very chaotic environment. Giving sedating drugs with antipsychotic properties makes sense. It’s not like kids are being sent there for being depressed or having anxiety. You have to have a major defect to end up in a mental hospital.

It doesn't have to be monotonic. For example f(x)=x, x<=0 and 1/x, x>0 is increasing in the negatives and decrasing in the positives, but it is true that for every x1,x2 if f(x1)=f(x2) then x1=x2

Given that flipping a coin and landing on head 3 times in a row is very very low probability, it can happen. The probability of landing heads 100 times in a row is even low but because it is not zero it is possible. Given an infinite amount of time to flip a coin can you get it to land on heads an infinite amount of times, given that the chance is not zero, this should eventually happen with infinite time. Right or Wrong.

A string can't be infinite like he says, but in addition to that, heads and tails is just a concept or a colour if you will, so an infinite series of coin flips can be only heads.

>> No.11980361

>>11979150
Given an arbitrary amount of time, you can get a coin to land on heads an arbitrary number of times in a row. Arbitrary is an important distinction from infinite. You can't get an infinite number of heads in a row - this would imply that tails would never be possible again.
