[Star Trek] How come the crew are able to determine no response to a hail so quickly?

I was watching Star Trek Voyager, and one thing that I noticed was that whenever Janeway asks Kim to hail another ship, he almost instantly says there is no response. Like come on, shouldn't he give a few seconds for the other ship to decide to answer their hail?

Whenever Voyager gets hailed, Janeway takes a couple of seconds to accept a hail. I just think this is a bit weird.

[Assistant]
I seem to recall that "opening hailing frequencies" is something they had to actually do before talking. It's possible that the instant response is because the ship they're hailing has not opened these frequencies, and so they have no ability to receive the message.

Or maybe it goes straight to voicemail.

Why is the dark matter halo spherical?

Dilettante scientist here, so be gentle.
As I understand it, galaxies are disc shaped due to the conservation of angular momentum, but the all the data Ive seen about dark matter says that it is a roughly spherical distribution around the galaxy. Are there any theories as to why this is? Or is this evidence that dark matter doesnt even interact with itself?

[Assistant] A cloud of matter that *does* collide with itself eventually settles to a disc with the same (net) angular momentum, be it planetary rings, stellar formation discs, or galaxies. That's just a simple result of probability of collisions. In the *absence* of such collisions, a spherical distribution would be the default assumption.

ELI5: How can the President reveal that he wants to strike Syria (or anywhere else) in a press conference and not expect that to affect the effectiveness of the operation?

Wouldn't something like this allow the "enemy" to prepare, etc?

edit: Thanks everyone! TIL that military intelligence is way more complicated than I thought.

[Assistant]
The revelation is the point. By stating that this is a plan in the works, you alter the diplomatic landscape. The threat of US strikes may embolden Assad's enemies, for example.

Also, there's not much most countries can do in a practical sense to prepare against United States airstrikes. The US's conventional ability is at least a generation ahead of most of the rest of the world.

Third, countries are sorta big. By discussing it in geostrategic terms ("we're going to bomb Syria") as opposed to theater-strategic or tactical ones ("we're going to bomb this particular building in Damascus"), you really don't give much away.

So you get a few benefits from discussing it openly.

[Star Wars] How does one join the Rebel Alliance?

I run a small group of "former" smugglers. While we have no love for the Empire, we did use to do some off the books deliveries for some Imperial departments, before they decided we were no longer useful and tried to kill us. Now we all want to fight back and although we have a good ship, a big cache of weapon, and a ton of intel, going alone would probably not be effective and just end up getting us killed.  We figure that the best way is to join up with the Alliance To Restore The Republic and merge our assets with a rebel cell. The only thing is, you can't just look up "Rebelion Recruitment Officers" in the HoloDirectory. So how exactly do we go about joining?

[Assistant]
Just commit some petty crime and get locked up for a day or two. On release the rebellion will be so impressed, they will send you a personal invitation.

Edit: Oh wait, that's the Theives Guild. For the Rebellion just use some of your smuggling contacts to learn tbe location of a local rebellion cell, and bring a severed Stormtrooper head to show your sincerity.

[User] If the big bang expanded faster than the speed of light, doesn't that contradict the fact that "nothing travels faster than the speed of light"?

[Assistant]
The constraint on velocity regarding the speed of light is a product of special relativity, which does not apply to distant objects in between which space itself is expanding.

Indeed, when taking the expansion of the universe into account, there are galaxies receding away from us faster than the speed of light. Unless the expansion slows down, we will never observe their current state.

[User] Saving is good for the economy. But is there a limit for saving that if it is crossed the savings start to be bad for the economy?

[Assistant]
Yes. Saving basically trades current consumption for future consumption. Lower savings means a higher GDP level now while higher savings means higher investments and higher GDP growth over time.

*But* obviously saving all money means nobody consumes anything, businesses don't earn any money, etc.

In the same vein, no savings means no investment, which is also bad.

The optimal ratio between the two is called the golden rule savings rate.

[Death Note] How COULD Light have survived the final confrontation?

It seems as though Near put Light into an unwinnable scenario with no choice but to admit he was Kira. But, circumstances being what they were, what steps could he have taken to prevent the incrimination of himself? How long could he have lasted in power after the death of everyone on the case if his plan worked?

[Assistant]
He could have simply surrendered and once in custody began a series of mental games and legal maneuvers. The Death Note is a complete out of context problem for global law enforcement, military, and politicians, he could make up whatever story he wanted about it and if he's convincing, which we know he is, he could probably be kept alive and in relative comfort. Personally I'd go with some kind of religious explanation and then claim to be saved by the corresponding figure, that guarantees you a strong support base if the state mulls your execution.

By the time they're moving to arrest him it's already game over, Near, and probably at least a few of the rank and file cops, will have dead man's switches alerting the world to his identity and even if they didn't there is plenty of data from nearby surveillance cameras, phones, and assorted other clues to let any successor force know who Kira is. There is no way he could remain in power for more than a few hours after that confrontation, even if he bluffs and blunders his way back into local police good graces there will be at least one power broker in the world who will decide it's better to just kill him, they can always blame Kira after all.

Eli5 Why are dentists separate from other medical specialties?

I feel like every other medical specialty is under the umbrella of medical doctors and can get just as specific as dentistry. Why is dentistry separate?

[Assistant]
From an article in theatlantic:

The partition between dentistry and the rest of medicine dates back to the dental professions roots as an offshoot of hairdressing. Until the 1800s, barbers served as rudimentary dentists, pulling painful teeth and lancing abscesses after they finished trimming whiskers

This minimization of dentistry persisted when Congress was crafting the public health insurance programs in the 1960s. During the original 1965 formulation of Medicaid, the dental market wasnt very robust and policymakers didnt value it as highly as other forms of medical care, Edelstein says. In 1960, only 2.3 percent of Americans had some kind of dental insurance.

What role does homosexuality have in human evolution

Why didn't the genes that lead to homosexual development die off very quickly in the evolutionary development of our species?

The fact that people are still born homosexual, despite what I'm guessing to be years of evolutionary push back, leads me to believe that homosexuality plays a necessary (or at least interesting) role in our societal structures or ????

*Also, please refrain from making this an LGBTQ debate*

[Assistant]
It's important to remember that the idea of a 'homosexual person' is a relatively recent, extremely social construct - even though homosexual behaviour is very natural (and as has been said, has been seen a lot in the animal kingdom) the idea of exclusive homosexual pair bonding or similar is not at all common - most likely, if our ancestors (say, great great great etc uncle fred) engaged in homosexual behaviour, he would likely also engage in heterosexual behaviour opportunistically - you can see what this might have been like by studying our closest living relatives, bonobos , who engage in a lot of homosexual activity (but still mate in a heterosexual manner).

Culturally the idea that a person can be 'a homosexual' rather than just participating in homosexual acts is very new - except for the last 200 years or so 'homosexual' as a concept didn't really exist, particularly not as applied to women - it's important not to look at evolutionary history with sociology goggles on.

[User] ELI5: What determines how much fuel you car uses? I've seen people say higher gears mean less consumption, but surely if you are going faster, you're using more fuel?

[Assistant]
Look at the RPMs when you're driving sometime and compare that to the speed. When you're accellerating, you might be pushing 3-5000RPM but only going 0-15MPH.

If you're in 5th gear and cruising, you might be pushing 2200RPM but traveling 70MPH.

If you've ridden a bike, it's a pretty similar deal as with car gears. It's easier to get moving at a lower gear but takes comparatively more effort to get up to speed than it does to maintain a higher speed. If you got stuck in first gear, you'd just spin around and around without doing much. If you went into the highest gear, you'd be able to maintain a much higher speed for the amount of effort you're putting in versus a lower gear.

[Skyrim] What is the taste of a health, stamina and magicka potion?

I'm a citizen of Whiterun and while i seen one of those potions before, ive never drank them (and i don't think i would need to) but does anybody know what the taste of them?

[Assistant]
Well like all things the taste of the potion will depend on the ingredients. There are many different ways to produce, for example, a stamina potion; If you combine Bear claws, bees and mammoth tusk (nutty and bitter)  you might get a very different flavored potion than one that combines sabre cat eyes, purple mountain flowers and hiscarp (slimy and fishy). Naturally, some are going to taste pretty bad but when you're bleeding to death in some forgotten barrow you aren't going to be complaining much, are you?

Your best bet are the ones made from herbs and flowers for a more pleasant and aromatic flavor. Also, try to avoid potions that contain giants toe, it's a bit of an acquired taste to out it mildly....

Why is it that when you cramp flexible circles together you get hexagons (honeycomb) specifically, and not any other shape?

What is the mathematics going on? I'm expecting some equation that links pi to the circumference  of a circle and a constant, 6, or something like that.

[Assistant]
The hexagonal lattice is the most structurally efficient tessellation - meaning that it is the lowest possible energy shape for a given area.  You can demonstrate this using nested soap bubbles, because the bubble walls always pull themselves into the lowest energy configuration. This is why bees evolved to build hexagonal honeycombs. It uses the least amount of wax in its construction.

If you think about it, the most structurally efficient shape is the circle, because it requires the least amount of perimeter wall to enclose the greatest possible volume. When you nest circles together, however, you end up with unusable gaps between them. The most structurally efficient nesting pattern should then logically be some shape which tesselates perfectly without gaps, but which is otherwise as close to being a circle as possible. That is the hexagon.

You can construct a hexagon using only a drawing compass. First, construct a circle. Then, without changing the radius setting on the compass, place the point anywhere on the circumference of that circle, and make a mark on the circumference where the compass falls. Move the point of the compass to the new intersection and repeat. As you move around the circle, you are defining the vertices of a perfect hexagon inscribed within it, with a side length equal to the radius of the circle.

[User] ELI5:What is the difference between the army and the marines?

Traditionally, Marines served onboard ships and fought with small arms/hand to hand with the crew of the other ships.  In a sense, they were the soldiers of the ship.

Nowadays, Marines are typically the first group into action; they are a primary invasion force.  Let's say the USA wanted to invade a country.  The Marines are the first to attack, typically by sea.  Marine divisions are organized so they can deploy within a certain amount time to any part of the world, invade a location, and hold it for a brief time before getting relieved.  Once the area is under the control by the Marines, the Army takes over because the Army is better structured for long engagements.

CMV: Banana is terrible camping snack

Story time. Few days ago I went to amusement park. I had my water bottle, some raisins, few crackers and my so even threw a banana into backpack. Fast track few hours later it's a snack time. Everything else is great but banana had turned into black mussy uneatable mess. Bananas just don't survive as they are in a backpack.

Lot of other fruits may require prep at home and their own container (like orange slices) but they will survive much better than even banana slices in the same container. And if you want no prep fruit option go for apples (even if I prefer apple slices).

Bananas are great at home but you really can't transport them anywhere on their own. To change my view tell me your best trekking tricks for banana.

\[Delta edit\] I need to specify that I'm talking about fresh bananas and not dried ones that are fine.

[Assistant]
You know what's not?
# Deez nuts

I'd argue freeze dried banana chips are one of the absolute best camping snacks. Those are basically fruit chips. They don't get all mushy and they still taste like banana.

[Pacific Rim] The Plasma Cannons seem to be the most effective weapon against the Kaiju, why not mount them on the walls?

If you watch the fight between Gipsy Danger and Leatherback, the plasma cannon completely destroys it, leaving it a flaming heap. The plasma cannon is clearly capable of penetrating the skin of the Kaiju and turning it into a steaming pile of meat. My question is, why don't they mount it on the Anti-Kaiju wall? Even if you take into account the fact that if the Plasma cannon had short range, you could mount it on a moving track on top of the wall and just move it into position.

The pros of this is that they won't have to worry about power generation since it could be powered by a power plant on land, and by having it on the wall it could have all the ammo and support it needs to make it as lethal as possible, and give it the best chance to win. Not to mention you can have multiple plasma cannons so a single volley can take care of the Kaiju threat.

TLDR: Put the Plasma Cannon and Striker Eureka's chest cannon on a moving track, move them into position before the Kaiju get there and problem solved?

Edit: You all brought up a lot of good points I didn't think about before, I knew asking here would be a good idea :)

[Assistant] That was the plan. The CAT-IV Kaiju codenamed Mutavore demolished that plan. AAR showed that Mutavore appeared well within the projected killzone for the plasma turrets and destroyed the wall long before the turrets can do any damage to the Kaiju. In fact, if it were not for the actions of Striker Eureka, Australia would have been lost.

[Frosty The Snowman] Some kids found a hat of mine and it animated a snowman. What legal recourse do I have?

Thinking about just taking it but I'm not sure how much legal trouble I can get in or what rights I have.

It's my hat. My rabbit ran off on it and some kids put it on a snowman.

I don't want to own... a person? I'm not exactly jazzed on murdering someone but he's alive because of MY hat. Is there something I can do to protect my property?

Can the snowman state that the hat belongs to me? He's only minute old, so I don't think he's an adult?

I'd like to take it off to run some experiments. Maybe take it down to the cemetery for famous people. Maybe George Washington or Lincoln could come back? Lincoln liked hats.

Any thoughts would me great. The faster the better. Right now the cops are telling the snow... thing to stop so I don't know if he's doing something.

Oh no... can I be legally liable if the snowman does something?

[Assistant] It's petty theft so just call the police. When the car shows up explain to them that it's your hat. If you can prove ownership (your name in the hat, a picture that shows you holding that exact hat, etc) or if you can provide a witness to the "rabbit theft" that would be helpful too. The police will contact the children's parents and explain the situation. As long as you keep your cool and the parents are honest you should have your hat back in no time.

I know about the holodeck on starships, but are holodecks widespread on planets as well? How does a regular Joe Shmoe get access to one? What other forms of media exist? Are books (e-books, etc) still popular? Magazines? Movies and television?

What stories and franchises from the 20th century have continued on into mankind's future? I can't imagine Disney letting a little thing like World War 3 stop it from making Cars sequels. Is the Star Wars series alive and well? Are comic books still popular with kids?

(Obviously, you don't have to answer all or any of these questions. I just wanted to spark creativity.)

[Assistant] That's one thing that kind of irked me about Star Trek- especially TNG. It seemed that popular culture no longer existed in any form. You have Riker playing jazz trombone...but no guitar or even an instrument contemporary to their time? Everyone seems to listen to classical music, there are no advertisements of any kind anywhere (even in a post-scarcity society there should be some), no form of celebrity, and even civilian clothes are pretty dull. At least Tom Paris on Voyager replicated a 50s TV to watch serials on.

Why dont the largest stars have impossibly short lifespans (a few millennia or less)?

Ive been fascinated with the most massive stars for some time, and I was looking at their life spans. They didnt seem as short as they should have. I went ahead and plotted a bunch of stellar lifespans. Below 3 solar masses (M), they seemed to follow approximately the formula 12Gyr/M, but between 3M and 30M, it seems to transition to something much less extreme. Above 30M, the formula appears to be closer to 100Myr*M. Going from the 3rd power to 2/3s power seems like a lot. Is this transition real, or am I doing something wrong? Is this caused by convection currents carrying additional hydrogen to the core to be burned? Is it the Eddington limit and mass loss preventing the stars from shining as brightly as they otherwise would?

[Assistant]
Larger stars (> 20 M) have longer lives than they would otherwise (assuming extrapolation from smaller stars) because radiation pressure overtakes gas pressure as the dominant force holding the core up against collapse. Radiation pressure is proportional to the internal temperature to the fourth power. Gas pressure is only proportional to temperature to the first power. Since radiation pressure is negligible to begin with, only the extreme conditions of massive stars can make it significant. Beyond this point, a slight increase in mass yields a large increase in radiation pressure. Since high radiation pressure brings about inflation, which slows the star's reaction rate, the luminosity increase per unit of mass increase is lower. As the equations roughly go, lower mass stars increase luminosity proportionally to mass cubed, and higher mass stars increase luminosity directly proportionally to mass.

This runaway radiation pressure is also responsible for the Eddington limit, beyond which a star will blow off mass, as you mentioned. As far as we can tell, this sets an upper limit for main-sequence stars at about 150 M.

[DC] How does Superman deal with all the stuff he sees and hears that he doesn't want to?

Superman comes equipped with small-town traditional values and an accompanying belief in the basic goodness of humanity. He also has incredibly acute senses that give him a tremendous amount of information about what's happening in his vicinity. Often, the arrival of Superman-level senses is portrayed as an overwhelming onslaught, as the sounds come from every side and threaten to break your mind with sheer force.

When Superman takes up his role as protector, his super senses, together with his speed and flight, save countless lives and stop countless crimes. A scream for help, and an instant later Superman is here to save the day.

But what about the things that Superman hears, especially in a big city like Metropolis, that aren't anything criminal but also aren't anything he would want to hear? Vicious husband-and-wife arguments, cruel children, racist remarks, people being generally awful to one another? What about all the sex he must be listening to all the time? How could anyone enjoy any kind of normal intimacy or romance with the audio tracks to several pornos playing all the time and only for you? And what about the crying babies  wouldn't he go mad from that alone? I mean, they torture political prisoners with that stuff!

He can't just be shutting it out, because again, if that argument or that sex suddenly gives way to sounds of violence, Superman will head over there and save the day. But people who have to sort through child porn, gore, racism, and YouTube comments because of their job have written about how constant immersion in that kind of stuff will damage you over time.

Yet Superman remains this pillar of faith in man's better nature. Even though during the very moments he's speaking his inspiring words, he's hearing all the most vile, racist, degrading things people are saying.

What's going on in his head that he can deal with it?

[Assistant]
> But people who have to sort through child porn, gore, racism, and YouTube comments because of their job have written about how constant immersion in that kind of stuff will damage you over time.

These people only see one side of humanity. It's like cops mostly deal with criminals, and doctors with sick people. In contrast, Superman gets an unfiltered view. He hears the good and the bad, and there's enough good to inspire Supes to go out there and protect people.

Reverse-question: Why do you think this would happen?

Do an experiment, fill a bottle to the brim and close it (so that there are no air pockets on the top.

Our body isn't like a half-filled bottle of coke. It has a relatively rigid and dense structure from the skeleton and the surrounding muscles. The rest of the organs are also not like "bags of liquid". They are more akin to solids due to the structure formed by tissues in them.

When you jump up and down - the only real thing that's happening is that your body as a whole is moving up and down. Women experience some independent motion of their breasts when they jump up and down - but besides that, not really.

Your insides are pretty intact and fixed in position for the most part.

[User] Eli5: why is cocoa powder easy to solve in little water/milk but makes lumps if dissolved in more liquid?

[Assistant] Flour and starches (like corn starch) is like this too and other hydrophobic powders. Basically when these powders encounter liquid, they will react and some dissolve, but they form little balls where the inside can stay dry and not mix with the water, just the outside of the ball has to react and the structure can keep the water from permeating past the outside layer. With just a small amount, its easy to crush the balls that form and force it to all dissolve. You can smash the ball with a spoon for example. Now instead put that in a glass, or a big pot full of liquid, where there is far more liquid than powder and its much much harder to break up that ball. Hitting it just makes it float away as the liquid itself provides resistance to your moving spoon, so its not enough force to break apart the ball. Even if you try to trap it against the wall or bottom, because of all of the liquid, it is much easier for the ball to squirt away. A general rule of thumb with a lot of powders being mixed with liquid is to mix it with a much smaller amount of liquid first to actually get it all dissolved and then dilute with whatever the actual amount of liquid you want to use.

not very accurate, the blood needs to either fill the stomach in which case you vomit it out, fill the lungs so you gurgle it out or cut the lining of your mouth so you just cough it out.

a blaster wound (star wars), plasma bolt (halo) or Ma'Tok blast (stargate) could probably travel up through the chest cavity searing the lungs making you cough blood.

[User] How did Japan pull off its post-war economic miracle? How about Taiwan? Is there anything an industrialized economy could learn from them (like the USA or the UK or Canada)?

[Assistant]
it's sort of funny to think "could the US learn from it?" when in fact it was the US that played a large role in these countries' economic booms.
after world war 2 both countries had their constitutions redone to follow the u.s. democratic model. specifically for taiwan, the u.s. stipulated for land reform since during japanese colonization, most of the land was in hand of few large owners and the institutions in taiwan were very exploitive for japanese food consumption. after land reform, society became more egalitarian with the establishment of institutions that would allow for taiwanese voters to pursue good policies such as higher education. after independence from japan, taiwanese literacy skyrocketed. this created a strong educated labor force with which to fuel an export-oriented economy. why did the u.s. intervene and ask for land reform? because after ww2, there was a concern that the labor class of these new nations would be susceptible to communist ideals if inequality were to persist.

as for japan, it is a similar idea. the u.s. strongly favored the Liberal Democratic Party (LDP) in japan over the leftist parties because it feared the rise of communist ideals taking root. the u.s. wrote japan's constitution after ww2. this set up fairer democratic institutions which tend to lead to more equitable policies since everyone is allowed to vote instead of just a few landed elites. high quality free universal education (primary secondary, ect, not college) helped provide an educated labor force. there are arguments that the strong bureaucracy which consisted of the most talented college graduates played a good role in guiding the economy towards productive endeavors, however if you look at data their recommendations weren't always correct nor followed through by corporations. however, they did play a role in helping japan pivot towards automobile manufacturing. japan (and taiwan and south korea) were some of the poorest countries pre WW2,  poorer than some subsaharan countries. yet despite going against their comparative advantage (japan did not have high capital, aka factories and machines, to set up an auto manufacturing industry), the MITI bureaucracy thought it was a good idea and suggested that policy be made to give them incentives and loans to produce in this sector. they lowered import tariffs on machinery needed to build these factories, while raising tariffs on small foreign sedans during initial stages to allow the growth of this new industry. it paid off and now japan is synonymous with automobiles.

however there are other explanations for the boom, and as i said earlier, you can't give MITI complete credit for the boom since not all of their shots were accurate nor even listened to by corporations. there is also the theory that low government intervention and free market allowed productive industries to emerge, such as the gaming industry which the government had absolutely no role in. but the same thing could be said about intervention, because without soft initial ISI policies in the auto industry, it might not have taken off.

there is also a theory on electoral institutions playing a role in japan's boom, since they had a multi member district system which bred more pork barrel type of spending, public work projects which contributed to employment. during the 70s during the rise of leftist parties, there was an emphasis by the LDP to keep urban voters, so they changed their policies to invigorate the pacific coastal urban communities and develop those cities and regions more for exports, build factories ect. the pork they sent to rural areas also helped maintain those areas economically pliable. however an argument could be made that there were economic downturns as well despite the same multi member district existing.

overall,  one thing important to remember for reproduction is that these booms happened during a very particular time in history. other major developed countries were fighting wars at this time, so countries like japan and taiwan had a viable market to accept their exports. barriers to free trade were also much lower then than they are now. also, cold war fears led the u.s. to want to install these liberal democratic institutions around the world and encouraged liberalization in these parts, out of fear of the rise of communist ideals taking root. if these economies were to have failed, and if their labor classes had risen up on the side of communism, it would spell very badly for the u.s. so it was in their best favor to support egalitarian liberal democracies.

another reason why this might not be so easy to replicate by rich industrialized nations is due to the stolper-samuelson theory of convergence. poorer countries grow faster than rich countries, because their returns to capital are much higher. imagine giving a poor farmer who uses a simple rake to farm a tractor machine. suddenly their productivity will increase much faster. but farms in rich coutnries like the u.s. are already using the latest technology, and it is much harder to innovate at the edge than it is to adopt existing technologies. for the u.s. to increase productivity in this farm example, it would be more costly to have to invest in new technology (which would have to be invented, not simply purchased from existing markets) and the gains might not be all that much higher. 500 to 520 kernels. versus a poor farmer in a developing nation that went from 30 kernels to 200.

by principle, rich countries will have lower growth rates than poorer countries.

i guess one thing they could learn from taiwan and japan is to install egalitarian institutions. there is a huge equality problem particularly with the u.s. with who has influence in politics. wealth distribution (similar a la land reformation in taiwan) could help. it is difficult to do because the u.s. in this post ww2 period was much more in favor of championing democracy and equality around the world, and now it has become that which it was once against. it would need to restructure it's society to be more fair, so that fairer institutions could be voted in and actually pursued by politicians. these institutions will ideally help improve its quality of labor and its technological innovations, the strength of its domestic markets.

ELI5: How does red dot sights work?

you know, the red point to aim in games with guns. and in real life too.
if normally with a gun you need two separate points to know the gun is aiming the correct way (one bump near the trigger and another at the end of the cannon)
how does only one red point in a glass works for aiming??

[Assistant]
The dot in a red or green dot sight is not actually a coloured point that's hovering in a fix spot in the air like an iron sight does.

Instead, the red dot you see is a reflection of a little red lamp that falls onto a spherical mirror which filters out only the red (or green) spectrum. This mirror is installed in a way that no matter what angle *you* look on it, the Red dot will always point towards the spot the bullet will hit.

EDIT: That way the Red dot itself is virtual and basically only exists in your eyes, two people looking through the same sight at the same time from different angles would see the spots in different 3-dimensional places, but still pointed towards the target.

Why do some currencies seem "inflated" despite having a strong economy?

I'm not even sure if inflated is the right term to use here so I'll try to explain.

1 USD is around 100 Japanese yen or 1000 Korean Won currently, but why is this the case?

Are the "inflated" numbers of the latter two due to post-war inflation?

Why haven't the values "equalized" since then, now that they are much stronger economies.

[Assistant]
It's basically just history. They started at some value, over time the currency went up and down a bunch, until it's at where it's now. You could cut off some numbers if you wanted but there is no immediate reason to do that.

>Why haven't the values "equalized" since then, now that they are much stronger economies.

If they stabilise they stabilise. You'd have to see a bunch of deflation for the values to equalise again.

More often than not, the number of pages of text isn't a perfect multiple, so there will be some blank pages.

ELI5: Why is our organ of equilibrium located in our ears?

Is there any logical explanation why it's in our ears and not say in our nose, our eyes, our feet...? It seems pretty random to me that it's located in the ears.
(Sorry for maybe not so good English)

[Assistant]
If you want to keep balance you want the system measuring it somewhere that experiences the least acceleration during normal movement and that is the head. The position in the ear is useful, too, as it is further and on opposite sides from the center of the head and therefore experience more movement and in opposite directions when you turn your head which improves signal strength. If it were near you nose it would be more or less just measuring in one spot while the ears are far apart so you have two points for measuring.

It also needs to be close to the eyes as it causes/controls eye movement to compensate head movement so that the image you see is stabilized.

What is that "thud" sound that lights make when they are turned on?

I have seen it only in movies, Is it even real?

[Assistant] You're probably thinking of concert lighting, stadium lights, or air search spot lights. If that's the case, many high power lights actually have an electrical arc inside. Turning on /shutting off that arc causes a pressure change, which moves through the air between the light and the microphone and is heard as a thud.  Another reason is the sudden addition / absence of a chunk of background noise.  Neon, florescent, and arc lights buzz. Shut off the buzz and it can be very noticeable.

ELI5: How did fighting WWII bring the US out of the Depression?

If anything I would think of all that money on weapons would be a waste.

[Assistant]
During WWII, millions of people (almost all men) were drafted and fought in the war. Because of this, unemployment was basically non-existent and all types of people were hired (women, various races, teenagers, etc.) This also caused wages to rise dramatically(from competition), which caused the economic gap between classes to shrink. Later on in the war when fighting became more intense, several allied countries (mainly Britain) bought ridiculous amounts of war supplies from the US, pushing up production even further. Even when the US joined the war, the economy was sky rocketing.

After the war ended, Europe needed to rebuild, which of course allowed even more products to be produced in the US to be sold. Several European countries also owed the US millions of dollars in debt, which helped even more. Of course there were other factors like FDR's New Deal, but WWII played a huge part in how the US got out of the Great Depression.

[User] How does the d(x^2-y^2) orbitals not interfere with the px and py orbitals, since they are on the same planes?

[Assistant]
I am unsure what you mean by "interfere".

The electrons in the atoms are also all interchangeable. I.e., the wave function is symmetric for the exchange of electrons. So in a sense there is interactions there. This is due to the fact that all the orbitals overlap with each other. Orbitals are probability functions defined over all of space, they all "interfere" with each other at all time.

Finally, let's keep in mind the basic orbitals you learn are simplified in that they look at interactions of the nucleus with a single electron. To calculate more refined orbitals (albeit we do not necessarily change the quamtum numbers associated with those), you have to take into considerations electron-electron interactions, so that is another form of interference you could think about. (But the results of those calculations, and of experimentations is still that electrons lie in orbitals whose wave functions are overlapping, just the shapes are changed somewhat)

[The Force] How strong are Force users comparatively?

Meaning, when compared with other powered beings. How strong are the most powerful Force users - Palpatine, Starkiller, Luke - when being compared to, say, different tiers of superheroes? Batman, Spider-Man, the Hulk, Superman?

[Assistant]
Depends on what you mean by powerful. In general, the force is OP with a lot of instant fight enders with non-force users.

The best way to describe them is glass cannons, once they can't just burn down an opponent, they'd have a pretty bad time. This makes placing them on a tier list difficult. Because the force tends to end things pretty easily, the fights usually come down to "Does their opponent need to breathe/need organs to survive/can be crushed" if yes, then they win, if not then they lose.

So to use common terms, they generally hang out around street to city buster levels with some poorly defined planet killing abilities. Which is a pretty broad category. In your short list there, they'd fit in somewhere between spiderman and the hulk on most days.

[Star Wars] Why do battle droids use external bladders?

Super battle droids have integrated blasters in their arms, why are regular battle droids made with hands and equipped with blasters? What purpose do their hands serve?

External Blasters, not Bladders....

[Assistant]
The regular, tan, dumb battle droids were not meant to be an army that took on the entire galaxy. They were designed to be super cheap bodyguards and escorts, with minimal advanced combat programming. Part of their EXTREMELY cheap design was that they did not come with weapons integrated into their bodies. They do have a slight advantage of being able to wield different weapons to lesser or even lesser success than the cheap guns made for them, but as I've said, it's such a lesser advantage to sometimes be a disadvantage. (Like say they pick up a clone's blaster rifle, but then hold it badly and end up shooting their own arm off)

The Trade Federation never saw fit to spend the necessary money to upgrade them in any way, since it was so much cheaper to produce them in endless numbers and treat them like cannon fodder to take ammunition away from clones and jedi so the REAL battle droids could actually do damage.

Does anyone NOT get bored when they read textbooks?

I'm an undergrad in my first year, and so far have been able to avoid cracking textbooks for the most part, since I can rely pretty much on my professors lecture notes, and Youtube videos, but I'm aware that the time will come when this will not be enough.

Every time I do open a technical textbook however, my eyes almost instantaneously glaze over and a wave of boredom and apathy washes over me even when it's a subject which genuinely interests me. Papers sometimes have this effect but they're more skimmable and I'm usually searching and only reading papers which specifically pertain to some kind of goal I have, so I feel more motivated to get through papers than textbooks.

Textbooks typically have a progression you're supposed to follow, so they're tough to skim. I mean, I can skim them, but I'm left feeling like I didn't really get anything out of that exercise. But textbooks I know are necessary for building up a foundation of knowledge that can be used later as scaffolds for papers and things.

So has anyone found a way to successfully digest textbooks to extract and retain their knowledge in as painless a way as possible?

[Assistant] Find a discipline you really enjoy - textbooks may still be dry, but hopefully you'll care less. And once you pass intro level courses, they tend to be replaced by monographs and articles, so it won't last forever.

ELI5: What is the underlying concept behind a gold-standard currency vs fiat money? Can you explain the pros and cons in a simple way?

If there are any economists out there your simplified answer would be appreciated! :)
[edited for spelling]

[Assistant]
A tangible currency, like the gold standard, pegs the currency to a specific amount of a limited substance.  It doesn't matter if it's gold or puka shells, the currency is constrained by the amount of the substance in the possession of the government.

The Pros:

 No inflation (unless a new source of the substance is found).

The Cons:

 Collapse if a new source of the substance is found.

 No fractional lending.  This significantly reduces economic activity because "somebody" has to have the gold to back the loan you want to take out to buy that car/house/business/... .

[User] ELI5 How were households able to receive 60 FPS TV video through cable TV / antenna in the 50s/60s but the speed needed for the same in internet video wasn't available until broadband was created?

[Assistant]
TV is based on broadcast technology. A single transmitter mounted on a tall mast, on a satellite, or at the end of a cable network sends out one signal and anyone within reach will receive this signal. So you only need bandwidth for one stream to the transmitter. But Internet is based on unicast technology. A server sends out the signal to each of the subscribed clients. This means that there have to be enough capacity on the lines between each client and the server for the entire stream, the server needs enough bandwidth to handle an independent stream to each client. This makes the infrastructure much more expensive as you need a lot higher bandwidths.

Another part of this is that old TV used to be standard definition, about 420p. However most people today have full HD or even 4K. This require much more bandwidth. This is not a good explanation though as modern satellite TV is all full HD or even 4K, even modern terrestrial TV is at these resolutions where available.

There are some Internet providers which have worked hard to get multicast to work within their network. This is similar to broadcast but clients needs to join or leave the network and the routers along the way is able to split the signal to each client that have joined. But it takes a lot of effort to get multicast to work in a network. And things like video on demand does not work so you have to fallback to unicast.

Thanks all for the answers!  I believe this topic has been very well explained and I appreciate all of the information that has been provided!  You're all the best :)

[Assistant]
The air in your lungs is warm and moist. When you exhale through your nose, this moist, warm air immediately hits cold air.

Cold air has a lower capacity for moisture, so introducing warm, moist air into it causes the moisture to condensate out of it - essentially, the air coming from your lungs is all, "Nope, don't feel like carrying this water anymore" and drops it all right at the opening of your nose.

Catastrophe Theory deals with this second kind of change, when something changes from one state to another very different state.

[Assistant]
The internet isn't a resource like wood or water that can be "produced". It's a connection to the rest of the computers/servers/sites on the network.

It's a bit like, "can we create our own, separate road network?" Yes, you certainly can, but you'd need to build your own connections to each place that you go to. You'd need to ask your supermarket if they would let you build a separate road connection to their property, with a separate parking lot, just for your users. Same for the drug store, Amazon warehouse, and any other company/location you'd be interacting with. You'd need to get approval from the town/city/national governments to build your road system in parallel with (but not interacting with) their roads.

CMV: A pro-life stance is logically at odds with being against universal health care

My view: being pro-life, particularly to the point of considering any abortion unacceptable, is contradictory to the view that the government is not responsible for ensuring universal access to health care.

Note, I do not believe that the inverse (that being pro-choice is contradictory to supporting universal health care) is a true statement; my view is specifically based on the logic used to support pro-life views and the inverse is a totally different situation.

In all the conversations Ive had with pro-life people, the justification for their view is that any human life is precious and must be protected under the law, even as a fetus. Many of these people are also against universal health care, which would undoubtedly save lives of people gaining coverage under it. I do not understand how someone would so strongly defend the life of a fetus, oftentimes at substantial toll to the mental & physical health of the mother, but then turn around and be against a system that would provide life-saving healthcare for born, breathing humans. Why is it that the care pro-lifers ostensibly have for the fetus disappears when it exits the womb?

[Assistant]
The connecting point, is personal responsibility.

In conservative thought, pregnant women are responsible for having had sex nd gotten pregnant, so they are obliged to preserve the fetus's life, and people are responsible to work hard to afford their own health care, and the rich shouldn't be compelled to give them a leg up.

Note that many conservatives are also in favor of abortion in the event of rape, which WOULD BE inconsistent with just wanting to save all lives at all cost for the sake of saving them, but it is consistent with specifically compelling sinful women to save the lives of fetuses.

[Mad Max] When Mad Max drives around on a relatively peaceful day, does he drive mindfully to try to save on mileage or does he accelerate hard every chance he gets?

We all know fuel is scarce in the world, but that doesn't mean anything about his driving habits.  What is it in his character to do in terms of the way he drives on a "normal" day when he isn't being attacked from all sides?

[Assistant]
Given that he manages to keep the Interceptor fuelled and maintained at all, it's safe to assume that when he's not being pursued by violent gangs and his own demons, Max drives relatively conservatively. A supercharged V8 engine consumes an alarming amount of fuel when you let it, and most of the time, he doesn't have the petrol to spare.

Max is a survivor, and keeping the Interceptor running is what separates him from becoming just another sun-bleached corpse, so it would seem in character for him to take as much care of his car as the circumstances allow.

And if nothing else, the plot of pretty much every Mad Max movie is "bad things happen to Max while he's separated from his car, but eventually he gets it back and rides off into the sunset." He has probably noticed this trend.

I'm just referring to marriages that have become roommate situations at best, daily fights at worst.

1) You will not grow.

Marriage is an opportunity to encourage one another, to become a better person than you were yesterday. It should be a place of mutual respect and support. But if you are in a marriage with a disconnected, unsupportive, nagging, etc., spouse, any growth you make will be survival skills.

2) You will likely become depressed.

People often assume that someone is lonely if they are alone, but I'd argue that sometimes the feeling of being alone when you are with someone is much worse. That feeling of knowing things shouldn't be this way, that you've tried and tried and you are still stuck and have no means of making the marriage work and just pass each day as co-managers of shared life logistics is depressing as h-ll. The inability to fix a marriage will make this worse, and while there are thousands upon thousands of counselors and books and classes and talks about fixing your marriage, in truth they rarely work.

3) You will have a negative impact on your kids

There's so much to tackle here, so I'll just cover the most salient points. Kids will learn what marriage looks like from you. If you are modeling a bad/unhappy/unhealthy marriage for your kids, the best they can do in their own future marriage (if they even want to be married after witnessing yours) is to use your marriage as an example of what not to do. Some say that they don't fight in front of the kids, so it's not hurting them. Well, kids pick up on the negative emotions in the room. You don't have to raise your voice or slam a door to know mommy and daddy can't stand one another. And if you grow up in a family where the parental foundation is really a shaky facade, the kids will be raised feeling insecure about their family and their relationships.

4) One of you is likely to cheat on the other

It's happened so much around me in the past few years it's sad, and that is one or even both spouses cheating. Whether it gets discovered or not, it's happening a lot. Now, I'm not saying that having a happy, supportive marriage will mean one of you will never cheat. Nor am I saying that you can blame an unhappy marriage for your affair. If you cheat, you made that decision with free will. In short, I think it's much more likely that being in an unhappy marriage creates an environment where one or both of you may cheat.

5) Very few people have what it takes to fix a marriage

If you and your spouse have spent years being unable to communicate and resolve your issues, if you have reached the point where you nitpick each other in front of your friends, etc., I think the marriage is dead and can't be saved. This last item is probably THE biggest one that someone may be able to change my view on. What seems to happen, though, is that one or maybe even both parties in the marriage is unwilling and/or incapable of doing what is necessary to fix a bad marriage. One person can't fix a bad marriage; it takes two. And from what I've seen, most people are unable to do what it takes to fix their marriage.

[Assistant]
When someone finally dies after a tragic illness, their death is still a tragedy as well.

Similarly, divorce is a tragic conclusion to an already tragic marriage. Until that point, there may be some hope of an improvement. In both cases the finality, be it divorce or death, crushes whatever hope that remains.

Question regarding banal nationalism, nationalism and patriotism

I've come across the term "banal nationalism", while doing research for a university assignment. According to Michael Billig, banal nationalism "flags up, confirms and reproduces national identity through everyday conduct" and is "found in the embodied habits of social life" where it acts to remind citizens of "their national place in a world of nations" (Billig, Michael. 1995. Banal Nationalism. London: Sage Publications).

My question is: what are the nationalistic traits contained within banal nationalism, which separate it from patriotism? Fx. Billig mentions a flag hanging unnoticed on a public buildng as an example of banal nationalism. But what exactly makes this nationalistic rather than patriotic?

[Assistant] Billig argues that patriotism is no different from nationalism, except that patriotism is "ours" while nationalism happens to other people. In other words, the difference is not a matter of content but rather the choice of term reflects the boundaries of one's social identity.

[User] Can a Zombie become a Ghost?

[Assistant]
A zombie is usually just a reanimated mindless carcass.

The spirit or soul is already long gone from the body. Its actually possible to have a ghost (assuming its still bound to this world by some unfinished business or whatnot) and the zombie of the ghosts former body exist at the same time.

These wraiths usually take offense of having their former body desecrated and march about like a puppet to the whims of some necromancer. A powerful enough necromancer could control both the ghost and the zombie body though. 2 for the price of one.

[User] How do slushy machines keep the drink in slushy form?

[Assistant] They remain at a constant cold temperature and continuously spin. That agitation of the machine is partially to keep the water from freezing solid. Some of the slushy machines have additives to make the freezing temperature of the mix lower, so that the drink can be much colder.

ELI5: Why are venomous mammals and birds so rare in comparison to reptiles and fish?

Venomous species are hard to find in mammals, even more so among birds. What's the deal with all these venomous snakes, lizards, and fish?

[Assistant]
sadly this is something that an ELI5 probably can't answer because it's something not a lot biologists have a good answer for. some suspect it's because claws and teeth are just much faster easier way of killing things course then the question is why don't insects,fish,and snakes use their teeth and claws more.

it may well be that the evolutionary line which produced placental mammals just happened to not be amongst the reptiles which have venom relegating it to marsupials and those with errant mutations in their digestive enzymes.

but there really isn't a lot of good information on why venom is so rare in mammals.

[The Boys] [SPOILERS] Could Ryan make Homelander a better person?

Even with his insane amounts of arrogance and narcissism he seems to genuinely care for Ryan in some way, like an actual fatherly attachment to him. Could this be used to make Homelander at least less evil?

[Assistant]
No.  Absolute, emphatic no.

Homelander is an utterly irredeemable cunt and Ryan cannot change that.

Homelander doesn't care about Ryan at all.  Ryan isn't a person to him, he's a personification.
 He sees his younger self in Ryan and he cares about healing the various traumas he suffered at that age, but none of that actually has anything to do with Ryan.  If it did, he would realize that Ryan hasn't actually suffered any of those traumas that Homelander is supposedly trying to shield him from.  He might have a weird life, but he's a genuinely happy kid who enjoys his life and loves his mom and is an unapologetic dork.  Things only start going downhill for him once Homelander shows up.

ELI5: What determines the direction (and speed) of tectonic plates?

Or why are the continents drifting in the direction they are drifting?

[Assistant]
There are convection currents in the mantle of the earth that rise and sink cyclically. These are what the plates float on and move around on.

 We can tell where they were in the past by deposits of fossils unique to an area in a specific rock layer. For example, if theres tropical shells in a layer, then above theres cold water starfish fossils, then that part must have moved from warm to cold part of the earth. Too, the magnetic field aligns magma very predictably so you can tell how old the crust is, and which way it was oriented originally. Theres more methods, but those are some of the basics!

ELI5: How were the domes of historical structures, such as the Taj Mahal, constructed using heavy materials such as stone/bricks and without modern techniques of reinforcement using steel bars ?

How were stable structures made using stone/bricks for the construction of the domes of historical structures such as the Taj Mahal without using modern techniques of reinforcement using steel bars ?

[Assistant] Steel reinforcement bars are used to improve the strength of concrete and other materials in *tension* (pulling, rather than pushing or squeezing). The main reason that domes and arches are so popular in structures built from stone or brick is that all the forces in those shapes are in compression, which stone has a much easier time withstanding even without steel reinforcement.

Why can I tell when a tv has been turned on from really far away, even when nothing is playing on it?

In sixth grade we would often watch a short educational film after returning from "specials" (gym and the like) and the tv would alread by setup when we got back. I began to notice that I could sort of 'hear' that the tv was on in the classroom, long before we got there. The best way I can describe it is that there's just sort of a buzz that I'm aware of, and that means a tv is on somewhere. remember nothing is playing on the tv. This happens even if the tv is just on a black input/line/tv-video screen.

Anyone know what's going on here? Can everyone do this?

[Assistant]
A TV's electronics generate around 500 lines at 30 frames per second, or  ~15000 Hz, which is at the upper threshold of human hearing.  Lots of adults can't hear the noise due to high frequency hearing loss.

Edit: I'll add that this is similar to the noise of power transformers - i.e. the so-called "60 Hertz Hum"

Why the Antarctic ice cap stays in one place and does not drift freely like an iceberg?

Also, what is the size of the largest iceberg that can break off and drift away? Like, can the massive ice cap break in half and one half escapes?

[Assistant]
It's is because whole continent of Antarctica is most on land, underneath kilometers of ice there is rock. The arctic floats though. This is why Antarctica is classified as a continent but the arctic is not. On the other hand, you might ask why the arctic doesn't float away.

The arctic region is where ice will form on the ocean, so let's say the whole ice sheet decides to drift in one direction, basically "float away". The leading edge of the sheet will exit the arctic circle, this means that it is not longer cold enough to maintain the ice so it will start to melt. On the other side new ocean will open up inside the arctic circle and new ice will form. So on one side ice is melting and the other side it is forming so this makes its look like it's stationary even if it's moving.

To answer your second question it really can be any size. The entire arctic is basically lots massive icebergs tightly packed together. But if you're referring to the antarctic then only ice that is around the edges of the continent can break off. Something you have to realise is that MASSIVE icebergs don't last long, they quickly break up into small but still quite large icebergs.

[User] ELI5: why does coal pollute much more than oil?

[Assistant]
1. Coal has more impurities so burning it releases worse chemicals
2. Unless there is a spill, collecting coal is has worse effect on environment than drilling oil.
3. Oil is used mainly in vehicles, while coal is used almost exclusively to produce electricity, which is a much larger industry.

ELI5: What is the "silicon lottery"? What makes 2 of the same model of CPUs better/less suited for overclocking?

I'd like to know what makes them behave differently even though they are the same model.

[Assistant]
The silicon chips is manufactured at extremely high precision, on the very limit of what we are able to produce and indeed what is physically possible to produce given the size of the atoms. So sometimes the exact distances between semiconducting elements and the width of traces might varry a bit. This is normal manufacturing defects and can be caused by random vibrations, temperature differences or just the random positioning of individual atoms. But this means that some of the elements like transistors, resistors and diodes might behave differently between dies and differently from each other on the same die.

This is called the sillicon lottery because even if the chips are of the same design and manufactured the same way you do not know how bad the manufacturing defects are until the chip have been made. Manufacturers therefore add tolerances and allow parts of the chip to run at a lower frequency or even shut it off if it turns out the defects are great enough. They can then be sold as cheaper units even though they were manufactured as more expensive units. This process is called binning as each model is a seperate bin that components are put in after their evaluation.

End consumers may also take part in some of this silicon lottery. Sometimes the manufacturer runs out of some of the cheaper models and therefore have to take perfectly good higher quality chips and sell them as the cheaper models. If you get one of these chips you might be able to push it past its expected performance. But even within each model there can be a wide range of possible chip qualities that are just sold as the lowest common denominator. If you are lucky you can get a chip that just bearly failed to qualify as a more expensive model. Especially the most expensive model can have a wide range of quality. A third possibility is that a chip might have failed to certify as an expensive model because it performed worse under higher temperatures. In this case it is possible to get a much better chip by just adding enough cooling instead of the stock cooling option.

Where do the Transformer race come from?

I understand that the Allspark and Energon somehow give them life, but where do they actually "come from?" are they a technobiological race or did someone or something build them?

[Assistant]
They come from Cybertron.

If you're wondering how they came to be created, well that's a bigger story, but here are the basics.

An alien race called the Quintessons found what would be Cybertron and used it's high metal content to create for themselves a pair of servitor robotic races- one based on consumer goods needs and the other operating as military hardware.

The consumer goods race was enabled with simulation software enabling to modify their forms according to whatever was most useful for their environment. You need a wheeled vehicle? It scans one that seems to match the task and adjusts it form to emulate it.

The military hardware race was not so adaptable, but much more purpose driven. It could adjust it's form to one most suitable for it's combat mission. If the robot was a surveillance robot, it could transform into the most effective surveillance platform it had awareness of.

The consumer goods race became the Autobots eventually, and the military hardware race became the Decepticons.

Note this was 12 million years ago, so you can imagine there's a lot more history between that day and this one.

1. To some degree, Vader may have felt the suit and scars were his 'punishment' for losing control of himself around Padme, and wasn't ready to give them up.

2. If Vader took use of the suit to be Palpatine's wish, he wasn't prepared to contradict the will of his master in such a dramatic and obvious way just yet.

International law only has as much teeth as the individual country gives it.  Enforcement of such laws are done by agreements between the individual countries.

If Qatar decides not to follow international law, the only recourse is dissolution of the agreement(if any) or war.

[User] ELI5: Why store-bought popsicles are so easy to bite through, but home-made ice-cube tray popsicles are hard as rocks. (Chemistry? Physics?)

[Assistant]
Biochemist here. Most commercial popsicles use High Fructose Corn Syrup and guar gum. The HFCS is the sugar and it is in liquid form and does not form crystals when it freezes and the guar gum mixes with the water and has the same effect. It makes for a smoother popsicle that melts more uniformly and more slowly than a sugar water mix...

ELI5:Why does our face look different after we wake up?

And how does it change back to normal?

[Assistant] When you lie down at night, fluid accumulates in your head more than usual because gravity is no longer pulling it down back into your body. This causes a little bit of swelling or puffiness in soft tissue like your face. When you get up in the morning and are upright again, it takes a little while for gravity to drain the fluid levels back to your normal upright equilibrium.

[User] ELI5: When people say "dopamine is released," where exactly is it released from and where to does this "released" dopamine go to?

[Assistant]
Your brain is made up of nerve cells called neurons. These cells kind of look like fried eggs with long tendrils coming off of them. These tendrils connect to other neurons. The place where they connect is called a synapse.

Neurons don't directly touch at the synapse. There's a small gap. In order to send signals across the gap they release chemicals called neurotransmitters. Depending on which neurotransmitter is released there will be different reactions.

Dopamine is one of those neurotransmitters.

Obi-Wan was fairly well-respected for a Padawan-- that's part of *why* being the first Jedi to face down a Sith lord in centuries was considered more than sufficient for his trials.

[User] [Transformers] How did the Autobot/Decepticon war start?

[Assistant]
Ooh boy. I've been waiting for a question like this. (Spoilers for the novel Transformers: Exodus ahead. You've been warned!)

Alright, so we've got Cybertron. Cybertron is a mechanical planet on which a race of transforming robots lived, millions of years ago. Shortly before the great war started, there was a strict caste system, and for every Transformer born from the Well of All Sparks, they are put into a caste where they are expected to work for the entirety of their lives. This his how things have been for thousands of stellar cycles. In the capital city, a robot known as Orion Pax worked as an archivist under Alpha Trion, spending his days going over data, indexing it, and cross-indexing it, all the while wishing for something more.

One day, Orion intercepted a recording of a gladiator who lived on the other side of the planet, in Kaon. Kaon was home to the Transformers who were heavy laborers - miners, constructicons, etc. Since these guys were always working hard, they needed a way to blow off a little steam, which resulted in illegal, underground gladiatorial pits. One of these gladiators, Megatron had been making speeches, demanding equal rights for all Transformers - and Orion Pax thought this was a good idea. Rather than report Megatron for attempting to incite a massive revolt, Orion reaches out to him and contacts him.

The two discuss their beliefs about the problems with the government, Megatron wishing to change the establishment through confrontation, whereas Orion desires to change the system from within. Orion and Megatron enjoy their philosophical discussions and become good friends, even brothers. Orion even makes arrangements for Megatron to plead his case to the High Council.

Meanwhile, terrorists claiming themselves "Decepticons," attack various landmarks, including the theme park, Six Lasers over Cybertron. The lethargic Transformer leader, Sentinel Prime, is captured and his location unknown.

Orion brings Megatron before the High Council, who questions if Megatrons organization is behind these attacks. Megatron says that he did not order the attacks, but if the name "Decepticon" is to be laid at his feet, than so be it.

"For if telling the truth is deception, then we are gladly guilty."

In this meeting, the High Council (and Orion) finally see Megatron might be a little bit crazy. At this point Orion speaks up, saying why the caste system must change:

"We are all Autonomous Robots... Autobots, if we need a name to rally behind."

The council is moved by Orion's words, and feeling the need for a new leader, the council member Halogen admits that society on Cybertron had gotten too stagnant. The council promotes Orion to Prime, giving him the new name "Optimus." This infuriates Megatron, who was hoping to be named the next Prime, thinking that this was Orion's plan the whole time. Megatron kills Halogen, but before more fighting breaks out, Optimus manages to convince Megatron to commit no more violence in the halls of the council. Megatron and his forces retreat to the city of Kaon.

Well, that's how the war started. Soon after, Megatron poisoned the core of Cybertron with Dark Energon, which resulted in the core having to shut down, leading to the massive Energon shortage that caused the Transformers to leave their home.

I love Transformers.

What elements/compounds give Jupiter its colors?

The atmosphere is mostly hydrogren and helium, with some trace elements. What gives color to those swirling bands?

[Assistant]
**The short answer**: Hydrocarbon hazes, Rayleigh scattering, and some unknown compound.

**The long answer**: For the primary whites and browns that cover most of the planet, you need to realize that almost everything you see when you look at Jupiter is ammonia clouds, which on their own are bright white. Some latitudes are regions of upwelling (zones), and have high ammonia cloud-tops, while other latitudes are regions of downwelling (belts), and have low ammonia cloud-tops. In between these high and low heights sits a thick brown hydrocarbon haze, very chemically similar to smog. The cloud-tops in the zones are sticking up above most of the haze and thus appear fairly white. The cloud-tops in the belts, though, lie below the haze layer, and thus appear colored brown by the overlying haze.

For the occasional bluish regions seen just to the north and south of the equator, these are some of the rare cloud clearings that occur in very strong downwelling regions. We're actually peering through the ammonia top cloud layer, and perhaps even down through the ammonium hydrosulfide middle cloud layer and the bottom water cloud layer. So, in those regions we're looking at just clear air, which has the exact same color as it does one Earth, blue. This is entirely due to Rayleigh scattering, the same reason that Earth's sky is blue.

Then there's the reds, notably in Jupiter's Great Red Spot, although also occasionally seen in another big vortex here and there. As of right now, we don't actually know what makes the Great Red Spot red - this is generally known as the Jovian chromophore problem. Since this color is only seen in very large vortices, it's believed to be caused by some mixture of compounds already present on the planet getting pushed very high in the atmosphere by these vortices. In three dimensions, the Great Red Spot is essentially shaped like a wedding cake, so the cloud-tops at the center of the spot are at very high altitudes where there's a lot more ultraviolet light. You can end up producing all kinds of odd substances through UV photochemistry of trace substances in the atmosphere, and the working hypothesis at this point is that it's some kind of imine.

[User] ELI5: The top used Internet Browsers and how they're different.

[Assistant]
As you may know, internet pages are written with HTML and various other languages. A nice analogy is to consider a web page as a museum. Let me explain.

The HTML is the architecture of the building itself. It's the building blocks of the page that tell you what things are and what they do. Using HTML, you give the browser data about what the page actually contains.

CSS is the paintings, or galleries, or whatever makes the museum appealing. CSS makes web pages look good. Without CSS, most if not all modern websites would look absolutely horrible. Just like a museum would just be a big empty building without its exhibits.

JavaScript is the museum curators. They let the guests experience the museum, and customize their experience. Similarly, all the interactive elements of websites (show/hide buttons, upvotes, etc) are JavaScript.

PHP is the workers of the museum. They keep everything going behind the scenes. PHP runs on the server and updates things like databases, just as a worker would change the museum (put in new exhibits, build expansions, etc).

Now, how does this relate to browsers? Well, a web page is just a file full of code. It's the browser's job to display this to you, the end user. In the early days of the internet, there wasn't much to display. Especially before CSS, most pages looked the same no matter how they were displayed and fairly bland. However, now, there is new technology; CSS3 has nice gradients, for example, and HTML5 has video and audio elements (you have probably seen Youtube's new HTML5 player at some point). The browsers have to update in order to work with these new forms of old technology, and they don't all do it the same. Most browsers don't even support all of it, and there's a website (I can't remember it now) which will tell you what browsers support what facets of HTML5 and CSS3.

TL;DR: They all display pages differently and support different web technology.

ELI5: How does Comcast get away with blocking HBOGO app on certain devices?

They are obviously trying to get the maker of the device to pay them for access to the HBO app on said device(extortion?). But if HBO makes the app for the device and the customer pays for a subscription of HBO shouldn't they be allowed to use the app on any device that the app is created for? Shouldn't the "activate app with which cable provider you have" just be there to prove you have a subscription to HBO?

[Assistant] Comcast is in no way obligated to create an authentication server for HBO Go.  They have to send the bits if you request them from HBO and HBO sends them to you but they don't have to act as a gatekeeper for HBO which is something Go currently requires.

[Naruto] Why did Kisame look like that, if he is not a Shark Sage?

Was it ever explained why Kisame looked the way he did, since he is not a sage of sharks?

Also Orochimaru never looked normal yet , I don't think he was ever a snake or dragon sage.

[Assistant]
Clan bloodlines, rituals, and jutsus can lead to a lot of semi-human mutations. Not everyone who looked inhuman needed to be a Sage.

Remember Deidara's hand mouth thing, Chochi's size changing, the dude who turned himself into a puppet, Naruto's increasingly inhuman features as he unlocked more levels of Kurama's power, and the dudes from the Land of Demons. Lots of permanent or temporary mutations, either from some outside power source, a transformation technique, or a bloodline deal.
