[User] ELI5: What exactly about sleep recharges the body and gives us energy?

[Assistant]
There's a chemical called Adenosine that builds up in your brain throughout the day. When it reaches a certain level, it makes you feel sleepy. When you sleep, your brain removes the built up adenosine.

I highly recommend the book "Why We Sleep" by Matthew Walker. It is full of useful info like this and tons more.

ELI5 how we learn to control our bladders when asleep?

I get how we do when awake but how do we learn to do this when snoozing when we dont have control over other things like snoring or sleep talking/ walking?

[Assistant]
When your bladder isn't very full, not peeing takes zero effort, as your bladder isn't trying to get rid of anything. As infants, we pee whenever the urge comes. With time and toilet training, we learn to voluntarily resist peeing until we have an acceptable place to pee. Importantly, the bladder fills slowly and the urge comes on over time, so there's a "I might need to pee soon" well before the "I have to pee right now." Only the second one requires conscious resisting.

With learning to stop bedwetting, we don't actually acquire a new skill as far as resisting urination, but rather that a full bladder should be a trigger to wake. The most effective treatments for bedwetting are basically alarms set off by wet sheets, which wake the sleeper. Over time this makes an association between "might need to pee soon" and "wake up." (We also get help from a nighttime increase in a hormone that restricts urine output.)

TL;DR: You don't learn to control your bladder while asleep, you just learn to wake up before you need to.

[Harry Potter] I have cast a spell on myself and am now troubled by existentialist doubt, AMA.

While walking around the shops in Knocturn Alley I became frustrated by the raucous nature of the carts that were trundling past as I was trying to cross the street. So I decided the best option was to cast a charm over myself that enabled me to always cross at exactly the right time to avoid the traffic.

For a few days I was happily wandering through the street, knowing that I was safe from harm. But now I am worried that the charm has taken away all of my free will. Am I walking off the curb at a time of my own choosing or is the spell in control of my every action and decision?

Have you tried the General Counter-Spell? You know, *Finite Incantatem*? It can dispel most simple enchantments, though it's not very effective against dark magic (even jinxes).

If it persists, please see a cursebreaker.

[User] ELI5: Why do different races have different hair textures?

[Assistant]
Hair texture is based on the protein composition of your hair and how those proteins interact together. Proteins are encoded by genetic information, which is hereditarily passed down. I'd assume that at some point in our evolution, as we moved out of Africa, either certain hair types came about that were either adaptively advantageous to the environment or were spontaneous mutations.

(more detailed answer on protein structure of hair) The structural component of hair is basically keratin, which is basically two helical protein loops coiled around each other. At the ends of these keratin strands are "head groups" that can interact with each other and bind these keratin strands together into larger bundles that become the hair you see. Depending on the chemical nature of the head groups, you can have coarse or fine hair, curly or straight etc. For example, more head groups = coarser, thicker hair. That's why, for instance, if you heat up hair you smell it "burning" (heating up the disulfide bridges that form the chemical bonds between the keratin head groups), and you can bend it into different shapes.

[MCU] What if Hank Pym has mentored Peter Parker instead of Tony Stark?

Let's assume that Pym became aware of Parker before Stark, and perhaps feeling some kind of kinship based on their similar insect related powers he decides to mentor Peter - not only for his own agenda but also for the greater good (which we have seen Pym is at least capable of being, especially with his daughter's influence) So with this scenario in play, how would the events of Ant-Man and ultimately Civil War and Infinity War have played out with this alternate version of Spider-Man in play?

[Assistant] Spider-Man with the ability to shrink would be amazing. He would not have mobility issues like Ant-Man because he would still have webs and speed. His strength would make attacks incredibly powerful when amplified by size ratio. EDIT: And there is something interesting about a spider leading an army of ants.

ELI5: Why have languages like Spanish not changed that much over the past several hundred years, but English has?

In my Spanish class recently, we read a story written in the 1200's, and it was perfectly comprehensible. I only had to look up a couple of the words. The grammar was a little bit archaic, but it wasn't difficult to understand at all. Compare this with, for example, the Canterbury Tales in English; these were written in the 1300's, and it is literally a completely different language from modern English. Even being a native English speaker, having looked at the Canterbury Tales in their original prose, I can only pick out the occasional word here and there. Even Shakespeare, which is considerably more modern, is, at least for me, harder to understand than very old Spanish texts. What has made English change so much, whereas Spanish has been so consistent?

[Assistant]
English experienced some major changes around that time that Spanish did not. In 1066 the Normans, who spoke French, took control of England. The fact that the ruling class spoke French greatly affected the native English language and a lot of French words made their way into the language.

Additionally, there was something called The Great Vowel Shift in English that happened from around 1350 - 1600, in which speakers changed the way they said vowels. The end of this period is also when spelling was becoming standardized, so you end up with some weird spellings trying to reflect changing pronunciations. Spanish didn't have a great vowel shift, probably due in part to the fact that it has fewer vowel sounds.

This combination of a changing vocabulary and pronunciation/spelling makes it hard for modern English speakers to read things written before the end of the vowel shift, but we can read most of the stuff that was written towards the end of that time such as Shakespeare's plays and poems.

[User] ELI5: With the new finding of the seven earth sized planets, how will humans determine whether there is life on them and how long would it take to do?

[Assistant]
The planets are 39 light years away, so getting a probe or something over there would take quite hundreds of years or more with our current tech at it's best. Fortunately, we don't have to do that.

The best thing we can do is to look for signs of the kinds of gases life makes: oxygen, carbon dioxide, methane. When Trappist-1's light shines through the atmosphere of one of the planets, we can watch for which spectrums of light are and aren't filtered out by the atmosphere, which tell us what types of gases are in it.

This is of course not SUPER conclusive, but we'll be able to get proper answers on it within the decade. And there's plenty of other exoplanets out there to try the same tricks on. We've been discovering exoplanets at an enormous rate lately, which is amazing since it took until 1992 to fundamentally find and prove the existence of planets around other stars, and now we've got bucketfuls of data about 'em to sort through and start oogling.

[Harry Potter] What was the rest of the magical world doing during the Second Wizarding War (Voldemort's return)?

In Fantastic Beasts, we learn about the existence of MACUSA: the Magical Congress of the USA. So this raises the question: Where the hell were they when Voldemort was out slaughtering Muggles, Squibs, half-bloods, and Muggle-born? He got Albus Dumbledore killed (or at least most people think he did). He killed the Minister of Magic and used the Imperius Curse on the next.

That part is what gets me. You could argue that, sure, there are lots of terrorists in foreign states that the world ignores, but Voldemort launched a coup, overthrew the Ministry of Magic, and *killed the Minister of Magic*: the head of a wizarding state. Why did the other wizarding governments not issue a global intervention against him?

[Assistant] I think you're giving wizards more credit than they deserve when it comes to organization and ability for organized action. It seems that getting involved in other nations' internal affairs is simply beyond their understanding - they're not exactly the usual 'Muricans.

[Assistant]
$97 million was spent on Oil and Gas lobbying in the United states. The United States is also rich in natural resources and is well set up for the refining of oil, meaning there is not  much of an incentive for it to switch to renewable energy besides being more environmentally friendly.

 On top of that the European countries that are leading in renewable energy are a lot smaller both in terms of area and population, meaning they need to produce far less energy and don't have to transport it as far.

Do we know of any right now? How big or small could they be?

I think that part of the difference between "flaming balls" and "intense light" is the variation.  There are certainly dull stars, and there are stars which are the various colors found in fire, but any star you can see is going to appear as a solid dot - whether that dot is solid fire-orange, ember-red, or blue.

The one he collapses onto the Hulk.  Buying a building seems like something that would involve lawyers and lots of paperwork, and not something that could be done in only 3 seconds.  Hell that's not even enough time for whoever owns the building to respond to an offer.

[Assistant] Unless it was up for sale with a buyout price, no, he likely wouldn't have been able to literally buy it then and there. But what he could do was put an offer on it. A pretty high one, probably a lot more than the building (which was still under construction) would ultimately be worth.

You could harm your immunity by eating a really bad diet, but living in a Western country youd have to work pretty hard at it. If you eat a remotely standard diet, youre doing just about as well as you can, immunity wise. (Unless you eat too much, since obesity is associated with increased susceptibility to many disease, for many reasons, including some effects on immunity. If youre overweight, though, adding foods to your diet wont help your immunity.)

CMV: its immoral to dig up ancient graves for archaeological research

I think that its disrespectful for tombs to be opened just to find artifacts. At the end of the day that was still a person who wanted to be buried in a way they could feel at peace.

Everyone sees ancient Egyptian art and offerings in museums that have been stolen from their burial site. Those objects were considered vital to their passing and religious ceremonies (from what I understand).

I say CMV because maybe there is more educational value (beyond historical) than Im seeing, and Im not very educated on the topic. But the concept is just gross. Mummies etc. should be left to rest not put on display in a museum.

I just dont see how its worth it. Sure, ancient civilizations are fascinating. But I dont think that should outweigh humanity.

People should be able to rest peacefully without being dug up and dissected.

There is endless education to be had, from diet to how people died, what medical procedures were done at the time, what diseases, etc., etc.

Also, in the case of something like Egyptian tombs, esp the ones of the wealthier or more famous -- looters have been looking for and looting those for centuries.

[MCU-Strange] Battle between the Ancient One and Kaicelius.

In the final battle between the Ancient One and Kaicelius, she manipulates the mirror dimension to separate Strange and Mordo from the fight. Why doesn't she separate Kaicelius' minions from the fight in the same way? For that matter, why not just completely dominate the fight with dimensional manipulation, wrapping up the baddies in the same stuff she builds the platform out of?

If the answer is that the baddies' dark dimension power gives them greater control over the mirror dimension, why don't they dominate the fight the same way? Is it just a coincidence that the magical power levels are so nearly tied that the fight devolves to melee combat instead of magical superiority?

I'm reminded of jedi battles, where it seems lightsaber combat is always the deciding factor. But, in that case, balance is an essential quality of the force, so it makes sense that few fights between force users are so lopsided that one can crush the other with pure force power.

[Assistant]
Dimensional manipulation power from the Dark Dimension comes from the same spell.  Hell, they probably used the same ritual to gain access to it in the first place.  Mordo and Strange are removed from the fight because they're basically helpless in this battle, but all of the disciples *do* have access, so even if she temporarily throws them off-balance, they can just bring themselves back to the battle in a few moments.

A spell is as powerful as the spell is, and there doesn't appear to be any personal influence in the 'power' of a spell.  It's similar to shooting a gun; an expert marksman will aim faster, and be more accurate, but once the bullet is fired it's going to do the same amount of damage to whatever it hits regardless of who did the firing.

'Power' in the magical world comes down to having the widest array of spells available (which is why Strange's photographic memory makes him such a prodigy) and experience (which the Ancient One has gained over hundreds or thousands of years).

ELI5: What is happening to a battery when it's charging?

What's going on to recharge a battery?

[Assistant]
Batteries don't produce any electricity.   Instead, batteries are electricity pumps.  The path for electric current is *through* the battery, then back out again through the other terminal.

As with any pump, in order to pump a flow of charges through the wires, energy is required.   This energy is stored in a sort of "chemical fuel" in one or both battery plates.  When a battery runs your devices, its stored chemical fuel gets converted into waste products.  It's a bit like combustion.  When all the fuel is gone, the battery is "dead," and the plates contain only the waste.

But unlike combustion, we can convert the waste products back into fuel: just force the electricity backwards through the battery!   Weird, eh?  It's like making gasoline by pushing your car backwards up a hill while pumping exhaust into the tail pipe.   Or more sensible: a battery is like a molecular wind-up motor: it can run down, but it can be wound back up by forcing it to spin backwards.

In theory, all batteries can be recharged.   But in practice, "non-rechargable" batteries have their plates destroyed at the end, when they're almost dead.   We can't restore the plates to their "fully charged" state unless they still exist.   Rechargables are designed so this doesn't happen; the plates never fully dissolve.   Even so, the plates don't perfectly rebuild themselves during recharge.   After many discharge/recharge cycles, errors build up, so perhaps the rechargable battery develops an internal layer of insulator, or perhaps the plates will electrically connect together (internal short circuit.)

Why does an TLS private key need to be thousands of bytes long, when 16 is more than sufficient for a password?

As I understand it, it's not safe anymore to use a 512-byte encryption key for TSL. They're too easy to crack.

On the other hand, a 16-byte random password is more than enough to foil any modern attempt at brute-forcing (that's ~ 10^29 possible ASCII passwords).

Why is it so much easier to crack TLS encryption than it is to guess a password?

[Assistant]
Increasing the length of a password increases the number of possibilities exponentially (your search space is the number of possibilities for each character ^(length of password) )

Public/private key encryption is based on the principle that if you multiply two large prime numbers together, and give that number to someone else, it's hard for them to figure out what the original two numbers were.

While there isn't a direct way to determine the factors of say 391, you only need to make 7 guesses to break the encryption(the space you have to search is limited to the prime numbers that are less then the square root of your "key" , but if this was a numeric password that had to be somewhere between 0 and 391, you'd have to make an average of 196 guesses to break the password. That's why the public key has to be longer.

ELI5: What causes us to choke on things we swallow?

When someone starts choking, all I have ever heard is that the person "swallowed something wrong" or "it went down the wrong pipe," followed by quite a lot of coughing and attempts to clear the throat.  Can someone please ELI5 what is actually happening? Is it because of really bad, um, swallowing technique or maybe swallowing something too quickly?  Also, why is it seemingly impossible to clear one's throat immediately after beginning to choke on something and the normal ritual of clearing the throat begins?

I have always wanted to ask but felt it might be a stupid question to ask someone in person, and I never thought to ask my Biology teacher back in high school.  I have choked on both food and liquids, of course, but nothing makes me feel stupider than when I choke on my own saliva lol...

[Assistant] When you "choke", it is because something other than air has entered your lungs. This can be a piece of food or aspirated liquid that you've inhaled (including saliva).  Coughing expels air and foreign material from your lungs, so you're not actually clearing your "throat"/esophagus, but rather trying to force out whatever has entered your lungs through your trachea/windpipe.

[Stranger Things] imagine a tactical nuclear strike with a high megaton nuke in the Upsidedown. What are the consequences, in our world or otherwise?

Imagine a navy seal team travels to the bottom of that lake and enters the Upsidedown through the Watergate with a 1.2 megaton nuclear bomb (one of the largest max yield nuclear weapons) and a drone kit equipped to carry the weapon once set up by the team. Upon arrival they set it up, the drone flies to Vecnas palace (or otherwise to the epicenter of the evil stronghold) with the nuke and explodes, encompassing/nuking a massive force of the creatures, including Vecna. What happens in our world? Are there any immediate consequences? Does the Upsidedown retaliate?

[Assistant]
We can safely assume that nothing harmful from the blast (EMP, nuclear radiation, the blast itself, and etc.) would affect our world, unless its at the gateway. The gateway between worlds would need to be shielded from the nuclear blast and its long term radiation Chernobyl style.

We can assume that a powerful nuclear detonation would be able to kill vecnuts, the mind flapper (if its in the main blast radius), and all the other creatures in range.

As for retaliation, the mind flapper will most likely be based somewhere other than vecnutss shack and not be in range of the main blast. The mind flapper would probably send a bunch of demigorgons and stuff until it can get a new vecnuts type minion.

When you hear a choir, are you hearing the average of all the singer's voices?

I don't know if my question makes sense. I guess I was thinking about it in terms of how it seems that if a large enough group is singing together, anything discordant isn't really audible. Actually, I don't even know if that's true. Is it? Please help?

[Assistant]
You're hearing the sum of all the voices in the chorus, so like the average but multiplied by the number of singers.  This is because the amplitude of sound waves simply add in air, which is an example of a superposition principle.  So if one person out of twenty is off-key they'll only be 1/20 of the sound, and their mistake will get glossed over to some extent.

That being said, if everyone was a spot on copy of one singer, they would produce a louder version of that one singer.  The distinct sound of a chorus is actually caused by the fact that not everyone can sing exactly the same, they are a little out of time and a little out of tune and have slightly different timbres to their voices.  Electronic effects try to emulate this by adding a copy of a sound that has been phase or pitch shifted to itself.  It works surprisingly well, but it's hard to fake the complexity of the real thing.

I know some might mention freakonomics but Im looking at ones that are more academic I guess. Especially ones that are more focused on monetary policy and macroeconomics.

[Assistant]
Sounds like Macro Musings with David Beckworth is right up your alley.

Econtalks is another popular academic podcast.

I like The Indicator from Planet Money because it's short but they still cram in tons of economics.

[Judge Dredd] Is there an in-universe reason Dredd is never seen without a helmet? Has anyone asked him about it?

New reader of 2000AD here, and I was wondering if there's any in-universe acknowledgement of this practice. (Unless he does remove it off-panel)

[Assistant]
He's removed it a few times; there was once a whole comic where he was helmet off the entire time, but it doesn't get revealed until the end.

That said, he keeps it on more or less constantly for a few reasons. One, it's his uniform on top of being his best protection against getting sniped or gassed (there's a little gas mask hidden in there). Two, he very strongly believes that presenting an image of being The Law is far more effective than the image of Just Some Dude, so he doesn't show his face a lot. Finally, Dredd's face is **fucked up** from years of service injuries and basically everything but that epic chin has been hit hard; veteran judges *flinch* when they see him sans helmet.

[User] Why are all LEDs roughly the same size? Could they be made much larger? What about much smaller?

[Assistant]
LEDs do come in different sizes. From the surface mounted ones used in old mobile phones, to the 3, 5 and 10mm ones you buy in electronics stores (these are the most common) to larger things like the luxeon star LEDs used in lighting.

Just consider it is more efficient and better for managing heat to have lots of smaller LEDs than one big one so manufacturers tend to stick to the mass producible sizes like 5mm, so lots of things have those.

[User] ELI5: what exactly is phlegm and why does it change colour based on our health?

[Assistant]
It's mucus.  Snot, just like the stuff found in your nose.

People think of mucus as being found only in the nose, but there's a layer of it that coats your entire respiratory tract, from your nostrils all the way down into your lungs.  It cleans the air you breathe by acting like flypaper: dust, smoke, germs, etc. get stuck in the mucus before they reach the lungs.  Wavy hairlike structures called cilia push it into your throat, where it drops down to your stomach to be destroyed.

You only really notice phlegm when you're sick, because the flypaper starts getting saturated with germs and with dead immune cells.  This changes both the color and the consistency of the phlegm.  Also, your body starts secreting a whole lot more of it to help fight off the infection.

[User] In winter bugs like spiders, flies and mosquitoes, seemingly die off. How is it that after the winter they're able to come back in such numbers? A layman would think the winter would cause an extinction of some insects.

[Assistant] Insects survive the winter months in a variety of different ways. Some migrate, like birds and other animals, to warmer climates from which they will return at the end of winter. Others can enter a sort of hibernation. A lot of insects will "overwinter" in some sort of non-adult stage of development, either as an egg, pupae, larvae, etc. This requires the young insects to be deposited somewhere warm and with relative shelter, deep underground or in the foundation of a building. Their genetics allow them to enforce this infantile stage of development until weather conditions permit.

ELI5:Why we stop having the urge to cry when hurt during adulthood?

As I remember, when I was small, about 5 years old, whenever I got hurt, I always cried, it was like this uncontrollable urge to cry. Now when I am grown up, I have never cried due to physical pain.

[Assistant]
A newborn cries A LOT. All the uncomfortable experiences/pain they will feel will be the worst pain they have ever felt. They don't have anything to relate it to. As the child grows up, things that previously made them cry don't make them cry because they've experienced it before and are increasing their threshold of pain.

For example, a 4 year old with a cut on their hand will cry because they might not have ever experienced it before, and the pain might be the most pain they've ever felt on their hand. A 15 year old with the same cut can feel the exact same pain but won't cry because by that point, they've probably felt worse pains. Pain can tend to be pretty subjective.

This is just one factor. Crying is a symbol of weakness, and adults don't like showing weakness (especially males). This is a cultural factor.

Also, adults have a much higher ability to rationalize.

Academics of AskPhil: what constitutes a great research proposal for a PhD?

I'm graduating my second masters soon, so it's time for me to start looking for a PhD position. Mind you, I am in Europe, I think stuff may work a bit different here in terms of graduate schools etc.

For nearly every position you have to write a research proposal that covers the what/how/why of your research. I have written some short ones, but a proposal for research that'll last 3 to 4 years is a different story.

How can I go about this in the best way? What should I focus on? How did you do it?

[Assistant]
I've just had mine accepted.

Our Research Methods taught module had a research proposal as one of its components.

The structure we were given to follow was the following:

Title/Question - The question you intend to answer in the thesis

Context - A survey of the literature and surrounding area to your question. Why is the question important. What contribution will it make to the overall scholarship.

Method - How you intend to go about answering your question. A rough division of the sections you intend to have in your thesis.

Bibiliography - The texts you intend to use.

Most of the proposal is in the context, then the method.

The expected length (including bibiliography) was about 1500 words.

How does the brain store data?

How is memory and thought stored within the brain? How then, is this... data conceptualised?

In a computer, jpeg data translates to an image. But then brain is of course, analog. And information is stored chemically? How is that possible? How is then, say the image of a favorite person stored within the brain? And then, when we recall their face - how does that translate into a mental image?

[Assistant]
The answer is more or less "it's not known", especially as you get up the chain towards "mental image", which we barely even understand phenomenologically.

But, roughly, it's known that information is recorded in the brain through interconnections between neurons. Each neuron connects to many other neurons; when it "fires", it stimulates the connected neuron by a certain amount, based on how strong the synapse connecting the two neurons is. If the receiving neuron is stimulated enough, it also fires, and the signal propagates and maybe does something interesting. These connections are the basic informational unit of the brain, and all higher-order information is ultimately encoded using these primitives.

This is a very low-level description of how brains operate, maybe the equivalent of how a hard drive works. We have SOME higher level understanding, but connecting the dots is difficult. We don't really have a "file-format" level of understanding, how specific images are encoded.

I think feminism is a radical movement and it actually has a negative impact in respect of equality. CMV.

I do accept the fact that for a very long period of time society did not hold women in a position of equality, in a lot of matters, some of which were and, more sadly, **still are** very harmful to the women who have to live in those circumstances.

I also accept the concept of equality of rights, because, we are all human beings and the concept of somebody being superior **just because** is, of course, nonsense.

What i don't believe in, is **ABSOLUTE** equality. Women are different from men - anatomically, emotionally etc.

I love the fact that I can pay for my wife's dinner and I don't consider it gender biased, be cause we **are** different. She is not dis-empowered and non-independent because of this. I think that women should be treated more carefully, as they are significantly more emotional than us guys.

The whole fact that we are ignoring this diversity instead of embracing it - and using it efficiently and harmoniously, is a severe detriment in my opinion.

All the more, the hate speech of some of the feminists directed towards the male population, representing them as lower life forms is another thing I don't agree with.

For example if it becomes mandatory to hire a percentage of women, it **might** be discriminatory towards men, if not all the women would be sufficiently qualified. Of course, there is such a thing as discrimination against women and this somehow prevents it, but I don't think that it is a permanent solution.

Schools should teach mutual respect for all human beings, and teach that diversity is good. I think that this would have a tremendous effect in 2-3 generations.

We need to understand that a speech oriented towards "males have ruled, we must now rule in order to be equal" is not a true speech about equality, but of vengeance and spite.

If the solution does not imply teaching respect and common sense, it will only widen the gender gap, and I think that this is what feminism does - it provides a unilateral, reverse-biased solution to the whole issue, which of course will only stir tension and hate.

**Thus, I think that feminism delivers hate speech instead of real solutions, and I think it does a great deservice to women worldwide.**

P.S. Don't give me the "feminism is not about that, you're wrong" speech. It is about how women are **better** and it mostly provides the same inflamatory speech about oppression and/or ani**males**.

**Edit: Thank you all for your contribution to the discussion. A clarification is due, I guess: I had zero previous knowledge of feminism, nor did I research it before posting here, so I didn't make a difference between feminism and extremist (or radical) feminism - the latter of which I strongly oppose and which is the subject of this post.**

**Edit 2**: What I argue is that people acknowledge that **women produce a lot more estrogen** than men, and that **men produce a lot more testosterone** than women do. **This causes us to behave differently**, and anybody who says differently is **blatantly** ignorant and against all science and common sense.

**Dear feminists**: The issue in a promotion shouldn't be about whether she is strong or frail and I don't get the emphasis on this matter. The issue should be: **does this *person* have the required technical and/or people skills to do this job well**? I think this is what you should be marching towards, instead of saying that men are not stronger ( I don't even care if they are or not, the issue is about skills and rights, not about strongness - what am I missing?).

**Dear extremist "feminists"**: You are bad people.

[Assistant]
>Don't give me the "feminism is not about that, you're wrong" speech. It is about how women are better and it mostly provides the same inflamatory speech about oppression and/or animales.

Do you think it's possible to cherry-pick examples of the most radical members of any group, and then use those examples to generalize across a larger group as if they were representative?

Say, Christians.  Or atheists.  Or liberals.  Or conservatives.  Or men's rights activists.  Or feminists.  Or [your choice].

Do you think it would be difficult to take any of those groups -- or any other that you chose -- and find a few self-identifying members who say idiotic things?  Do you think it's reasonable to hold people responsible for the words and actions of others on the basis that they may have *some* beliefs in common?

CMV: I believe determinism should be the dominant philosophy and objections to such are simply due to lack of human understanding even with mounting evidence.

This has been posted before and is a fairly common topic. People typically make objections such as quantum mechanics. Now quantum mechanics simply bring up that we can't predict the location and momentum of a particle. But scientists such as Einstein object with that we are simply ignorant of hidden variables. It i only fairly recent in history that we could use physics to predict anything at all. We just started understanding genetics recently and it is hard to imagine the brain isn't the next frontier. I'm not even sure I'll object to the idea that we can't predict everything. But I do feel confident in saying that every year we are understanding the universe more and creeping toward determinism and away from the concept of randomness and free will. In a poor mathematical analogy: the limit is approaching complete determinism, while it may never reach it.

Simply put: Every year we are moving further away from true randomness and free will. Why not believe the trend will continue indefinitely?

[Assistant] If hidden variable theory has no more predictive power than nondeterminism, on what basis do you suggest that we are moving away from nondeterminism? What is this mounting evidence that suggests hidden variables exist or that nondeterminism is false?

[Hellsing] What is it like for the souls of Alucard's devoured victims?

So Alucard can eat people's souls, trapping them within him, right? He can use their abilities & knowledge, summon them to act as minions, sacrifice them to heal himself from extreme damage, and perhaps more.

What is it like for the trapped souls? Are they conscious? Do they feel anything?

Probably not fun. Based on Pip and schrodinger i imagine they are at least semi concious in there,maybe more.
Even if they only semi-concious, watching alucard murder people violently forever(ish) doesnt sound like a good time.
If you lucky, maybe you get to rest in relative peace after he uses your soul to heal from a fatal wound. (or you get to die again and rest after he kills you a second time to come back from not existing)

ELI5: Why does a healthy cell sometimes produce a cancer cell

An healthy cell keep dividing until it is no longer needed. A cancer cell is a cell that uncontrollably keeps dividing itself.

How does smoking, asbestos, radiation, UV light, processed food etc. affect the normal process and make a healthy cell produce a cancer cell?

[Assistant]
So every time your cells divide, they need to make a copy of the DNA in the cell. This process isnt full-proof though, and errors can happen. These errors usually dont cause problems, since small errors might not make any difference to how the cell operates. The problem comes when too many errors start to occur and the cell completely malfunctions. Your body can sometimes recognize this malfunctioning cells and get rid of them, but sometimes these cells multiply too fast or are able to hide themselves from being destroyed.

Radiation, smoking, chemicals, and a lot of other things can cause more errors to happen in your DNA.

Undergrad considering applying to graduate school

I just finished third year of an undergraduate computer engineering program. I'm currently doing a one year internship, after which I will return to school to finish my undergraduate degree. Many of my colleagues (undergrads themselves) and some job interviewers have told me to consider attending graduate school, and I need to decide soon so that I can take the GRE, complete applications, etc.

On one hand, I do feel that I haven't learned enough in undergrad to satiate my personal hunger for knowledge or to be useful to any of the companies I'd like to work for. A course-based master's degree is an option, but I don't think it's as valuable as a research-based master's degree for personal growth, and making yourself look good in the eyes of prospective employers.

On the other hand, I have no research experience whatsoever. Those who recommended that I consider attending graduate school have done so based only on my transcript. Not only does this weaken my application, but it also makes it difficult for me to evaluate whether or not I have the aptitude for a research-based master's and whether I'll get what I'm looking for out of it. I think I have done well in undergrad because of the relatively rigid structure: take these courses, read these books, pass these exams. But graduate school is nothing like that, so I'm unsure whether it is right for me.

To top it all off, I don't know any of my former professors well enough to ask for a letter of reference. Some know me as that kid that did well in their class, but that's it.

**TL;DR: I just finished third year of undergrad computer engineering. I want to keep learning after undergrad. I have a good transcript, no research experience and I don't know any of my professors well enough to ask for a reference letter.**

Is it worth it for me to apply to graduate school? How can I, at this stage of undergrad, get some research experience (hopefully a recommendation in the process) and/or more information on whether or not grad school is right for me and whether I have what it takes to succeed in grad school?

[Assistant]
One logical first step would be to arrange a meeting with one of the profs of the classes you did well in. Even if they don't remember you, you can set up a meeting to discuss the idea of going to grad school, and ask them about what you should do. They'll have the best idea of what opportunities exist in your area. Reaching out to people who don't already know you like that is how you begin to build a network, and pretty much everyone has to do it at some point or other.

So just e-mail one or two of them and try to get them to chat with you. The worst that can happen is that they don't reply, or say no.

[Assassin's Creed] The hell is up with Ezio's moral compass.

Ok, Ezio systematically hunted down Rodrigo Borgeia's underlings, killed them all and god only knows how many guards and soldiers just doing a job to pay the bills.

Then it gets to the mastermind behind it all and suddenly it's all mercy and "killing you won't bring my family back".

Ok, then when Ezio rescued Christina from the castle in rome, he must have killed a dozen guards in the process. But then it comes to getting the key from Lucrezia and he has to frogmarch her down to the cells because he can't just kill her (or even just knock her out) and take the key from her pocket.

Seems like Ezio's morality is to refuse to kill when it will majorly inconvenience him to not do so. Almost like he's trying to drag out the "plot" of his life, as it were.

[Assistant]
Animus magic means it probably didn't happen *exactly* the way it's portrayed.  Given how dangerous open combat is, and the lack of any historic records of mass death by means of hidden blade stabbing during that period of history, it's quite likely that the historic Ezio was much better at moving unseen than we are when we control his Animus memory.

We don't lose sync when we kill guards because he does remember sometimes killing guards, but there's nothing to say he actually killed these specific guards.  After all, we don't lose sync for sneaking past them either.  When it comes to extremely memorable people, like Rodrigo or Lucrezia, Ezio recalls exactly how he dealt with them, and the memory plays back accordingly.

[User] CMV: The #blacklivesmatter movement is shooting themselves in the foot by interrupting Bernie Sanders political events.

[Assistant]
Perhaps cynical, but they might believe that

1. **Disrupting political events like Bernie Sanders' are an effective way to get media attention**: Sanders and his audience are too nice to let goons tackle and remove the protesters, so they get basically a free stage in front of the press with no time limit. The press is already there for Sanders, and the event becomes even more newsworthy when they disrupt it.
2. **Disrupting the events of the _actual_ Democratic candidate for the 2016 election would be going too far**. They want the Democratic side to win, and also people would hate them for harming that candidate.
3. But, **they believe Bernie Sanders has zero chance of getting the Democratic nomination.**

In this perspective, Bernie is going to lose anyhow, and by callously stepping all over him, they can promote their agenda without actually harming the Democratic cause in 2016.

There is no shooting themselves in the foot here. The only downside to them is their conscience might be telling them it's wrong to use Bernie like this, but that's pretty much it.

Bernie Sanders is collateral damage, but they don't care about him.

More heat: more energy to the molecules.

More energy, more movement, the molecules will weaken and cut the low energy bonds that let them stick together like hydrogen bonds or Van der Waals bonds.

In this way fat molecules won't have a strong grip on other fat molecules.

Whats the difference between liquid and gas?

I know this many sound like an extremely simple question, but on a molecular level, what's the difference between a liquid and a gas?
From a young age we're shown a collection of diagrams showing how the structure of molecules in solids, liquids and gases differ. In diagram of the solid, they're touching, in the liquid, they're spaced apart and less structured, and in the gas, they're even further apart.
My assumption has always been (feel free to correct me if I'm wrong), that difference between a solid and a liquid is the molecules 'touching', there molecular bonds. When a substance becomes hot enough that's its molecules have enough energy to break there bonds, it becomes a liquid. We have a definite point in which a solid becomes a liquid.
Equally, there is a definite point when a gas becomes a plasma, when the molecules gain enough energy that there atomic bonds begin breaking down, making a soup of protons electrons and the works.
...but what's the definite point between liquid and gas?
Are there any properties that a gas has the a liquid does not? Theoretically, if we had a liquid and a gas of the same density, how would they behave differently?
Maybe a slept though a key part of my year 6 science classes and missed something. Help me atone for my younger laziness reddit!

[Assistant] The molecules/atoms in solids aren't really "touching," they are just held tightly together by weak intermolecular forces. There is an energy level at which the molecules/atoms are able to slide past one another despite the intermolecular forces, but are still held together: thus the liquid state. In a gas, however, each molecule/atom has sufficient energy to move entirely independently of it neighbors, which is why a gas will expand to fill it's container etc.

[Star Wars] How did Vader ... un-fall?

In the prequel trilogy, Anakin's forbidden love for Padme leads him to the Dark Side. Right. Maybe it's that he was scared, or angry, as a result of his love; maybe it was just love, there's little difference.

But ... fearing for his *son's* life turns him good again? Getting angry at his old master for taking his son away, and murdering him - the *same thing* that Luke refused to do to save his friends - redeems him?

Did Vader ever actually reject the Dark Side, or just Palpatine?

[User] ELI5: centuries ago, how did they find the other planets in the solar system? Also, is there a possibility that there are other planets in our solar system that we have not yet found?

[Assistant]
Mercury, Venus, Mars, Jupiter and Saturn are visible to the naked eye and have been known about and studied since ancient times. Early astronomers noticed that these "stars" appeared to change position compared to other stars and so they started to track thier motion across the sky. The word planet actually means "wandering star".

Uranus had been observed but thought to be a star. It took the invention of the telescope to make accurate enough observations to track its movement. Eventually its orbit was calculated with such precision that astronomers noticed oddities that could only be explained by the presence of another planet - which turned out to be Neptune.

Astronomers also thought they saw a similar disruption in Neptunes orbit and so predicted yet another planet. When Clyde Tombaugh pointed his telescope at the patch of sky he expected "Planet X" to be, he discovered Pluto.

We now know that this was a coincidence, and there is no Planet X. Pluto was found because the outer solar system is full of these small icy dwarf planets and Pluto was just in the right place at the right time.

[Breaking Bad/Better Call Saul] How would the disappearer go about doing what he does?

Ok so he puts you in a truck and takes you somewhere, lots of traffickers can do that. The tricky part is that the new social security number he gives you is apparently good enough to allow you to go to the Hospital and have it checked with no issues.

[Assistant]
The only possible explanation is that he has serious connections.

As for the exact mechanism, there are a few possible explanations. One {purely hypothetical} possibility is that at some point, a fake identity is "born." All the documentation is filed properly, birth certificates, Social security, etc. The person doesn't actually exist, they're just being planted in the system as early as possible. Then, 20-30 years later, a client who needs to be disappeared comes along, and the disappear-er fabricates the details to make the two people one. All the legitimate aspects of the non-existent person are handed off to the client, and they assume the identity of a nearly blank slate, a non-person born exactly for that purpose.

[Star Wars] If Palpatine had willingly gone with Mace Windu when they came to arrest him, and the Jedi could find undeniable proof that he was a Sith Lord, but no proof at all that he was involved in the Clone Wars. What would have happened?

Would they still consider him a danger? Would the members of the Senate insist on releasing him, or would they appoint another Chancellor?
Would the Jedi even be able to keep him arrested considering that Palpatine was loved by the Senate and the public, who probably did not even know the difference between a Jedi and Sith?

[Assistant]
There was absolutely no way the Jedi would have "won" in that or any scenario. Palpatine's religious beliefs are of absolutely no concern to the senate, and the Jedi trying to arrest him for his personal opinions about spirituality show massive and unconscionable intolerance. It's the kind of breach that even an extremely bloated and corrupt Republic could NEVER ignore. A Republic built on accepting everyone no matter their differences cannot stand for a private religious organization dictating religious decrees on its citizens.

The word "sith" means nothing to the galaxy, because the Sith order have intentionally made it that way. If the galaxy were told of Palpatine's actual genocidal beliefs concerning the galaxy and Jedi, it would have done jack squat. It wouldn't have mattered if the Jedi had tons of documents proving that the Sith are evil, power hungry, and corrupt. It would just sound like the ravings of religious zealots trying to usurp the lawfully-elected supreme chancellor. In a time of war, trying to remove the symbol of power and stability is the height of treason. The Republic had literally just suffered an attempt by the Separatists to do *just that*, so the Jedi would have looked no different in the Galaxy's eyes, no matter how much concrete proof the Jedi had of Palpatine being evil.

The entire galaxy would have clamored for the immediate arrest and punishment for the Jedi that had clearly lost their minds, and probably asked for the entire order to submit to an extremely unfair series of sanctions. Hell, the Republic might have even attempted to lawfully arrest every single Jedi in the galaxy and detain them in one place if they all agreed that this religious intolerance could no longer be acceptable. (which would conveniently be destroyed in one way or another, exterminating the entire population of Jedi in one fell swoop. Collateral damage be damned.)

Palpatine would be seen as a hero a thousand times over for bravely resisting the actions of a bunch of superpowered terrorists, which we kinda saw him do in canon anyway, and the clone wars would be ended in much the same way as well. If the Jedi's attempts to spread the truth about the Sith made it to any kind of holonet media, Palpatine would have it squashed and forgotten, just to make sure future generations didn't get any seditious ideas.

Both. Kind of.
Firstly, it's worth pointing out that what we consider races are really one of about five groups: black, white, Asian, southeast Asian, or Amerindian. <EDIT:> **Most** <END EDIT> Jewish folks are an *ethnic* group that most would consider white.  EDIT 2: There are significant numbers of Jewish populations in India and Asia, and they are...well, primarily Indian and Asian populations.  There are also Jewish populations in Eastern Africa made up of Africans.  But the primary population of people that we would identify as "Jewish" are those who arose from a population of Mediterranean Arabs betwen 5 and 6 thousand years ago, and began their primary diasporic wanderings 3,000 years ago, with another massive spread about 2,000 years ago.

Ethnic Jews (of whom there are many subtypes) have certain genetic traits, just like ethnic swedes or Italians or Koreans. These traits are the result of, just like all other groups' traits, thousands of years of interbreeding with similar people.

An ethnic Jew might not be a religious Jew, though.

Judaism as a religion is one of the three monotheistic relations that grew out of the eastern Mediterranean, and it's the oldest.  Judaism as a religion exists outside of ethnic boundaries, although there is a lot of overlap that is not seen in the other large religions (I do not consider Zoroastrianism to be large). Judaism can be practiced by ethnic Russians, Zulus, or any other group that wishes to convert. And of course there are different flavors of Judaism, just as there are different flavors of Christianity.
Hope that helps!

[Dune 2021] What happened to humans?

To be more specific, I don't mean "Where did humans go?" Several characters refer to humans or are referred to as humans in the film. But there seems to be a distinction between humans and other peoples, like Fremen and House Harkonnen. Are these people not considered human? Did they evolve to be different enough to be considered different species? Is it just THAT far in the future?

[Assistant] The Bene Gesserit draw a distinction between people able to prioritize rational thought over instinctual reactivity and those that arent. They call the former humans and the latter animals. That is what the hand in box test that Paul undergoes is supposed to determine, whether he has the ability to override his instincts and fear and instead endure the pain to prevent his death by the poison at his neck. The Bene Gesserit breeding program is supposed to select for the human traits.

ELI5: Why is produce at ethnic stores so cheap?

**Edit**: Cheers! So, some combination of tiering in the quality of produce, in which 'ethnic' stores buy the least pretty but otherwise totally fine stuff (TLDR; Japanese will kill you for a pretty watermelon), and maybe also non-food factors, like non-union labor, greater share of revenue from cash-based transactions, little expenditure on marketing and aesthetics, and use of loss leaders.

[Assistant] So i work at a fruit packing company and can further explain what some of the others have said. There are different tiers of quality for produce when it gets packed, they are called classes. The three classes are: Class 1 which is export market(Japan, korea, China etc.) Class two is domestic market (Safeway, Costco, Target) and class three; peddler. For class 1's the fruit must be perfect in the box, zero defects and sizing must usually be accurate at no more than 6% error. Of course because the labor is more intensive the price is premium. Class two standards are  usually at 8% defect and sizing error. Class three is peddler quality, sizing errors are okay, weird shaped fruit and so on, but as long as it passes USDA inspections were okay. The fruit for class three has the most visual defects, not really affecting the quality of the fruit but not the most visually pleasing. Most ethnic markets/flea markets/roadside fruit stands buy class three. A box for class three might sell for 20 dollars depending on what fruit it is, whereas a class 1 might sell for upwards of 100 dollars.

[User] ELI5: Why is wanting to chew ice a sign of anemia? Why do you wanna chew ice if you have an iron deficiency?

[Assistant]
I don't believe there is anything humans used to eat, that was ice-like, that ever gave us iron.

Pica is a mechanism to eat more diverse food sources, as a means to get the nutrients needed to survive that are missing from a diet, as a last ditch effort, by eating things that an animal doesn't consider edible. Normally this would be a good way to get sick, but when malnourished this might be a risk worth taking.

For example, lots of animals have odd dietary habits like licking rocks, for salt intake. Pica could be seen as a biological mechanism to get a goat who doesn't think rocks are food, to start licking them again. The same underlying forces are probably at work with humans, too, when they have a vitamin deficiency.

[Assistant]
Battery capacity - Because AA batteries have more battery capacity than a AAA battery. Filling the empty space with some conductive material with AAA batteries would mean this device will run out of juice faster.

ELI5: How does extreme couponing actually work?

I've seen the TV show, and I don't understand a thing about how that can actually work in real life. Double coupons, etc. Any good stories or tips are welcome.

[Assistant] As far as the show... It's all bs, the grocery stores actually ignore the small print just for the show... The one that says not combined with any offer etc. The way it actually scans is because the upc of the item, that is the Barcode number is not a serial number per se. It more identifies the brand of product and other vague stuff... That said, in some occasions you can just take one of the coupons for let's say 8 Oz redbull for a buck, but if you scan it when buying the 16 Oz then you just won the grocery store... You would think that there cashier is paying attention but that's not the way it works, you do all yours homework before you show up, then stack up on all the savings, go to the register, scan everything, bag it, put it in a cart and right before you pay you whip out the stack of coupons.

[User] ELI5: Why is the 40-yard dash the magical number for gauging a football player's speed (as opposed to some other metric)?

[Assistant] While coaching Ohio State University Buckeyes football team in 1941, Paul Brown emphasized team quickness. One way to calculate this was for him to time his players covering a punt. At the time, the average punt went about 40 yards from the line of scrimmage and had a hang time of about 4.5 seconds. He would then time his players to see if they would be able to cover an average punt, or run a 40 yard dash in 4.5 seconds.  He continued with this strategy after becoming the head coach of the Cleveland Browns. The practice gained popularity from others as years went on and is the standard today.

Eli5: how does alcoholism run in a family?

I under stand cancer and diabetes but if alcohol is an out of body deal how it is it possible for it to be genetically in a family?

[Assistant]
Biochemist here--Our genes code for proteins that impact many things that can relate to alcohol addiction, including how our body metabolizes (breaks down) alcohol, and how our brain responds to it.

In particular, some people inherit DNA that makes them have a higher liklihood for their brains to enjoy alcohol and to become biochemically dependent on it. This can also occur for other substances too, even cigarettes.

There can also be other traits and conditions that someone can inherit from their parents that can make them more prone to alcohol misuse, such as biopolar disorder and ADHD.

edit: The expression of these genes can be affected by environmental conditions as well, so it can get very complicated.

Are there Lagrangian points between the black hole in the middle of our galaxy and the sun/earth?

So Langrangian points are points where gravitational forces of two things cancel themselves out, right? If so, Are there Lagrangian points between the black hole in the middle of our galaxy and the sun/earth? And can we be trapped in such a point somehow on our journey through the galaxy? What would change for us (even if it's not likely/possible)? Is this possible for any other black hole?

[Assistant]
> So Langrangian points are points where gravitational forces of two things cancel themselves out, right?

No, not right. They are points where the combined gravitational force of two things is just right so that a third thing can co-revolve with them. The total force isn't zero, it's equal to the centripetal force needed to orbit at that distance with the same period as the two primaries.

> Are there Lagrangian points between the black hole in the middle of our galaxy and the sun/earth?

Yes, in theory, but the gravitational forces of both bodies would be so weak there as to be pretty much negligible. Any nearby bodies would completely swamp them.

> And can we be trapped in such a point somehow on our journey through the galaxy?

No, even stable Lagrange points don't prevent objects from leaving them with propulsion, or even just being carried through by their own momentum. Getting things to *stay* at a Lagrange point is the hard part, not getting away from one. And, any way, the forces would be tiny in this case, as mentioned.

> What would change for us (even if it's not likely/possible)?

Nothing. There would be no impact on a trajectory through the galaxy.

>  Is this possible for any other black hole?

Is what possible? There's nothing special about black holes as far as distant objects are concerned. Their gravitational field is no different (more or less) from a hypothetical non-black hole object of the same mass.

Would it be inappropriate/insensitive to ask my department coordinator to notify me in case of a certain professor's death?

I'm a grad student, and I'll be finishing in about a month and moving across the country. There was one professor (other than my advisor) who I talked with quite a bit and really care for, but we're not close enough where his family would notify me if he were to pass away. He is 91 years old (and still working!) and has had two major health scares in the past year.

I really would want to attend his funeral in the event of his passing, but I'm not sure if it would be insensitive to ask my department coordinator to notify me in that event, since obviously the department members aren't openly discussing the possibility of his death. I just feel like once I graduate no one will remember me/think to contact me, and I would want to be there.

Thanks for any advice!

[Assistant] You can always ask to be informed if he ever leaves the university, since you'd like to attend the retirement party.  If the coordinator mentions other ways of his "leaving the university" you ask be told of those as well.

ELI5 Cauterising

So in movies or other media, a common follow-up to an amputation or grievous wound is to cauterise it. I understand it burns the end bits and prevents blood loss etc but if a person had an amputated limb, what happens to the blood flowing into the missing limb via artery? Cauterising doesnt just stitch arteries and veins together so does the blood just sit there?

[Assistant] Arteries and veins don't directly link normally either. All the blood gets distributed into capillaries where it can interact with your cells and only then does it get to the vein. If some part gets cut off, the blood will just get redirected into the remaining capillaries.

ELI5: Why are fire trucks kept obsessively clean?

I bike past my local fire station every day, and I see the firemen scrubbing the whole truck fleet down almost every week.

Other city vehicles (police cars, other trucks, etc.) Aren't necessarily dirty, they just don't have the shimmering glow one sees when a fire truck drives by.

Why is this?  Does the cleanliness add functionality to it?

[Assistant]
Because they have a hell of a lot of time between calls where they are basically doing nothing.  It's exactly the same in the UK, when they aren't fighting fires they're cleaning the fire engine.  Police cars are always dirty because when cops have down time they are out on patrol.  Ambulances are always dirty because they're in constant use.

[Warhammer 40k] Citizens of the Death World of Krieg, who was more evil, the Autarcs of Krieg or Horus?

And if you are still able to talk and have not had a siezure for considering it AND have not beaten me to death for asking, why?

[Assistant] To ask the relative depths of evil is inconsequential. In the perfect light of Him on Terra, any heresy is of grave severity worth of death. Clearly, the Archtraitor Horus was the greater servant of evil, leading thousands of planets astray from the light of the God-Emperor, and daring to raise arms against His Holy Person. However, the sins committed by the Autarcs against the Emperors representatives are grievous in their own right. Heresy, in any form, must be rooted out and atoned for. It is a blessing of the God-Emperor Himself that we are allowed to atone, in an infinitesimal way, for the sins of the Autarcs.

Does purposely letting my laptop 'drain' the battery actually help it last longer unplugged than keeping it charged when I can?

Also, does fully charging an electronic good really make a difference other than having it fully charged?

[Assistant]
No. Lithium-ion batteries (almost certainly what's in your laptop) gain no advantage from being discharged fully before charging.

Older Ni-Cad batteries (and possibly also older NiMH batteries) suffered from a so-called 'memory-effect' that could give them less capacity if not fully discharged before charging, but even those technologies have improved in recent years.

Under what conditions does a virus "die"?

Viruses (bacteriophages specifically) are energetically neutral. Given that they can effectively just float around until they encounter a host cell, do they deteriorate after a while? What determines how or when they are destroyed?

[Assistant]
A virus is inactivated when one or more of several things happen. The structure of the virion can be damaged to the point where it can no longer contain its genetic material, for example, the lipid envelope of the influenza virus can be disrupted by detergents. The binding proteins on the surface can be damaged, or otherwise permanently prevented from the ability to bind to their receptor on the target cell. Also, the genetic material itself can be damaged to the point of being nonfunctional, like with UV radiation.

A virus lacks the ability to repair or replace components of itself once it has left the host, so any damage to the binding ability or reproductive ability renders it effectively dead.

Eli5 Why unemployment in developed countries is an issue?

I can understand why in undeveloped ones, but doesn't unemployment in a developed country mean "everything is covered we literally can't find a job for you."?

Shouldn't a developed country that indeed can't find jobs for its citizen also have the productivity to feed even the unemployed? is the problem just countries not having a system like universal basic income or is there something else going on here?

[Assistant]
A big thing to remember is that unemployment very specifically means people who aren't working now, but want to be working. To a certain degree, unemployment is a good thing. The most common type of unemployment in a developed country is supposed to be frictional unemployment, that is someone who is unemployed because they are in the process of changing to a new job or are entering the work force for the first time. Having this at a reasonable level is important because too little means the people have given up hope on becoming employed and too much means many people have all quit their jobs all at once, neither of which are good signs.

The other types of unemployment represent problems in society, such as structural unemployment wherein people are unemployed because while jobs are available, they aren't in the right place. Unemployment of this type is a large driver of poverty in developed countries, most commonly due to formerly strong manufacturing bases have moved elsewhere in the world and left the workers behind - it's not that there aren't jobs to be filled, it's that there is a mismatch between the skills people have and the jobs that are available to be filled. It is not unheard of for formerly major cities to have all but completely died because their jobs have moved to a different location, leaving behind a collection of workers specialized in making something that is unneeded or is more easily traded for.   This forces people to have to either restart their education from scratch or move to a place that is hiring. When applied to a national level, that is a big problem.

How long does an arrangement of particles have to be together to be considered a new element?

What is the minimum half-life of an element?

[Assistant] The question is mostly about how long does a system need to be bound to be considered a new element. Well new elements are super heavy. They decay by alpha decay or fission. Typically you would define a new isotope by whether or not it is bound. So the time scales for how long it is bound depend on the decay mode. The shortest time scales would be around 10^-22 seconds. Of course new elements last longer than that right now. Elements around 118 decay in milliseconds, which is much easier to measure.

It would be spectacular to witness, and the intense energy released from the collision in your twisted doomsday scenario would burn whatever side of the planet was facing the moon at the time. Any chunks of rock or whatever that rained down upon Earth as a result would be akin to nuclear devices detonating in rapid sequence, unleashing a firestorm the likes of which Earth has not seen since its infancy.

Basically things would probably be pretty bad, but we wouldn't survive long enough to live through the hellscape that would remain of the thoroughly broken planet that remained after orbital lunar-bombardment.

[Assistant]
It does not.
All of the producers submit power to the same grid, and all of the customers get power form the same grid.
Even in countries where the power production market is a free market, the distribution grid is managed by a single company as it is considered a natural monopoly.
Every producer sells power to the grid at a certain price, then the grid sells that power to the customers. The thing is that in the case of little private customers, instead of buying from the grid they have a contract with an wholesale company that buys power from the grid and ensures the power supply for its customers.

Because the game involves sufficient input from the player to make it happen that it is considered a 'transformative work'. Films don't have that interactivity to make them go.

[Star Trek] What would be the outcome of the Dominion War and the state of the Galaxy if Gul Dukat had stayed with the Dominion?

How would things be different if Gul Dukat had not remained behind on DS9, eventually falling under the influence to the Pagh Wraiths and instead stayed on as the leader of the Cardassians under the Dominion?

[Assistant]
It would probably differ very little. Between the Cardassian retreat from DS9 and the battle of Cardassia Prime itself, most historians agree that Cardassian action had surprisingly little effect on the course of the war.

The first battle of Chin'toka was won despite a Cardassian tactical advantage, not for lack of one. Dukat could have done nothing to save the orbital platforms from his office on Cardassia.

The second battle of Chin'toka was won almost single-handedly by the Breen.

Nameless and minor Dominion victories throughout the war have been attributed mostly to the staggering quantity and loyalty of Jem'Hadar troups.

Finally, there's the X factor of the Founders' disease. No one knows where it came from, but it certainly wasn't Damar. Ergo, swapping in Dukat makes no difference.

Cardassia's role in the Dominion seemed to be primarily that of logistical support and base of operations. It seems unlikely that Dukat could have done much to influence the size of Cardassia's resource base.

There is one possibility, though. Dukat was famously deceptive, guileful, and manipulative. Had he somehow gotten wind that the Romulans were planning to join the war, he may have been able to change their minds through some unknown scheme. Had he succeeded--though we have no idea what he would have done--the result would almost have certainly been a Dominion victory and the subjugation of the Alpha Quadrant.

Atmosphere is just a layer of gas on the surface of the planet. Their composition varies a lot; Venus' is incredibly thick, but Moon's is so sparse that it weights just a few meager tons.

But why does Earth have one? There just was enough gases to form one. Gases are lighter than solids or liquids, so when gas is produced one way or another it starts to climb above the heavier materials.

We _currently_ have an atmosphere because Earth has enough gravity to keep it from floating away and a strong enough magnetic field to keep solar radiation from eating it up.
