[ "Dont happen as often... But authoritarian states are more likely to have coups since they relay heavily on both police and military (and many times a mix of both) to retain control, So In a democracy or a free state, the police is controlled in a civilian manner and the army has political and civilian oversight, while in Autocracy the millitary and police tend to have less oversight, to make their job easier... So its easier for higher ups in the army to roll out the tanks and get rid of the army. A good example is Turkey, Turkey has had several coups, even while being a democracy several Islamic themed parties in the past have tried to impose more autocratic rule and were overtrown, while the current president before starting his reforms and road towards autocracy first took the time to dismantle the control over the army and replace key military leaders to people loyal to him to prevent this. Also popular satisfaction in autocracies tends to be quite lower, so they wont bother if the army goes out and kills the president." ]

[ "It's difficult to measure neurotransmitters directly, since they are quickly metabolized. But we can measure their metabolites. For example, metanephrine is a metabolite of adrenaline, and homovanillic acid is a metabolite of dopamine. These can be measured in blood, urine and CSF (fluid drawn from the spinal cord). It is used to diagnose certain tumors. These tests are not used in psychiatry, but I suppose they could be. You might need to know a patient's baseline levels first though. I did a quick search and found [this study]( URL_0 ) showing higher homovanillic acid in schizophrenic patients, and [this study]( URL_1 ) showing higher metanephrines in ADHD patients." ]

[ "The modes by which electromagnetic waves interact with things are different, and they have to do principally with their wavelengths and their energies. But in a general sense, any machine which produces any kind of electromagnetic radiation could naively be called an antenna. It's just that the production method would be largely different. Radio waves are the product of an alternating voltage over the radio antenna. There's not too much to do with the excitations of specific electrons in atoms. The characteristic energies of these sort of excitations (where electrons move between atomic energy levels) produce radiation from visible light to x-rays, depending on the exact energy gap. Gamma rays are defined as originating from within the nucleus of an atom, by the rearrangement of protons and neutrons releasing energy. So a gamma antenna would necessarily be a nuclear antenna, in a sense. Another thing to note is that all objects emit electromagnetic radiation by virtue of having any temperature above absolute zero. At temperatures we find here on Earth, that is primarily in the infrared region of the spectrum." ]

[ "Imagine you're shipwrecked on a deserted island. After figuring out the initial survival details, eventually you and the other survivors build a simple economy, using a bunch of monopoly money from a board game that washed ashore. As the coconut collector, you find and sell coconuts for a hundred dollars apiece. One day, a cargo container washes ashore. Your small group of survivors opens it to find a whole shipment of monopoly boards. \"Amazing!\" you all cry. \"We're rich!!!\". You gleefully hand out a billion monopoly dollars to everyone in your small community. Tomorrow, someone comes up to you and asks to buy a coconut for $100. You've got a billion dollars, are you really going to spend hours looking for coconuts for a measly $100 now? So you tell them no. They go shopping around trying to find someone else to buy a coconut from, but no one cares about $100 now that they're rich. So, the desperate and hungry person starts begging to pay more. He'll give you $500 for a coconut. $1,000. $100,000. $10,000,000. Finally, someone agrees to find a coconut for $100,000,000. Coconuts used to cost $100, but now they cost $100,000,000. Why? Simple -- because coconuts didn't get any easier to find, you all just got a bunch more monopoly dollars to pay each other with. In the end, the same thing happens in the real world. If you create more money (e.g. by printing US dollars) without creating more value (by finding more coconuts, or baking more bread, or building more cars, etc.), you get inflation." ]

[ "The song has clear sections that sound distinct from each other, and each of those sections is fairly short with repetitions, rhymes, and/or clear imagery. So you've got the visual in your head, you're hearing the specific melody for that section of the song, and it's easier to memorize that part without consciously deciding to do so. Contrast to other songs that have a certain melody for the verse, a certain melody for the chorus, and then those 2 melodies alternate with each other to form the song. You might get mixed up as to which lyrics go with which verse because the melodies for those words are the same, whereas with Bohemian Rhapsody, once the first section is completed, that melody is not repeated again in the rest of the song. It's also why the bridge of a lot of songs tends to be the most memorable part, because it stands out from the rest of the song. In BR all the parts stand out from each other." ]

Blow the balloon up and try to throw it with the exact same amount of force you did with the uninflated balloon. It'll sort of float a bit then land at your feet. To get the balloon moving at the same speed it was going when it was wadded up is going to require a lot more force due to the air resistance. So that beach ball has got a lot more force and momentum behind it than it would have if it weren't inflated." ]

[ "We can produce wealth with time or resources. Let say you buy 1000$ and 2000$ of workers to build a mining equipment that you can sell for 5000$. You can created more wealth. What if the person that bought that equipment started to mine material and start to sell it. He also just created wealth. So now if you don't print more money your amount of money will stay the same, while the wealth of your country will increase. Money will increase in value over time because more wealth than money will be created. If money gain in value, product will decrease in price because their value didn't increase (that deflation). It will become a good investment to just sit on your money for a long time because that money will gain value by itself. If people prefer to keep their money and wait, there is less people ready to invest in company. Without investment company can't grow as fast and less wealth are created. Less wealth created equal less job created and you start to have economic problems. Now a way to combat that is to print more money. If you print more money the value of that money won't increase over time. So now you print money faster than wealth is created. There is more money to exchange the same value of product so now the value of money is decreasing and the price in going up. If that process is high, then all the money you put aside is also decreasing in value. Basic product become costlier everyday and what you put aside become valueless a lot of people now have a hard time to pay their rent and for their food. You are in a recession. So if you don't print enough or too much money you destroy your economy. The goal would be to print just enough money to compensate the wealth gain. But that's impossible to estimate with such precision the wealth gain. So you either allow a little bit of deflation or a little bit of inflation. A little bit of deflation and people will still have a little incentive to keep their money instead of investing it. But a little of inflation and people will want to invest their money, which will help the growth of the economy. So a little bit of inflation is better and that's what we try to achieve." ]

[ "Your bladder is made of a very stretchy type of tissue called transitional epithelium. It can change size rapidly to hold and release different amounts of urine. The bladder has stretch receptors in it, and when they detect the bladder getting full they send signals to your brain that it is time to pee. However, there are many signals that can interrupt and interact with this stretch signal that your bladder sends to the brain. For example, when you are nervous you can experience an urge to urinate that has nothing to do with your bladder’s size. When you are feeling threatened, you can not realize you have to pee until your bladder is far fuller than it would normally be when you felt the urge to urinate. The nervous system is complicated, and while some of your urge to urinate is governed by physical stimuli, some of it is governed by your emotions and other sensations your body is experiencing." ]

[ "> packed in what? Themselves! Know how when you dive under water the pressure on your eardrums the further down you go is because of water pressure. Way down at the deep end you have the weight of all of the water that is above you trying to push down and compact the water that is around you. Think of our atmosphere like a giant air swimming pool. Air doesn't weigh a lot, but if you have enough of it, it can add up. Thankfully we've evolved to breathe and be fine at the bottom of our \"atmoshphere swimming pool\"... and why as we go higher (climb a mountain, fly a plane), we find it harder to breathe - our lungs expect the air pressure to be ground level, but up way high its a lot less. To continue my lame swimming pool example. So lets say you have a pool heater that is shooting hot water into your pool at one end. Hot water and air tend to rise vs. cold water/air. The warm water rises, drawing cooler water from the other end of the pool at the bottom. Meanwhile the warm water spreads across the top of the pool and now you have a nice little circulation current around your pool. The streams of high and low pressure are essentially the same thing but working in our atmosphere swimming pool. The things that cause heating and cooling of the air are the sun, either reflecting off snow, or being absorbed by ocean, change in season vs. the hemisphere you're in (which in turn changes amount of sunlight), any radiant energies absorbed by landmasses etc." ]

[ "Quantum computer can evaluate combination of inputs. Let's say you have two people that say either yes (1) or no (0), and you have to decide whether they agree with each other. On classical computer, you ask the first one, then you ask the second one, then you compare the answers. You needed to ask **two times.** On a quantum computer, you can ask both of them at once. Or, better said, you can ask a \"combination of them\". You ask *first one + second one.* The answer will be precisely the thing you want: * 0 + 0 = **0** (mod 2) * 1 + 0 = **1** (mod 2) * 0 + 1 = **1** (mod 2) * 1 + 1 = **0** (mod 2) So, if the *combination of the people* answers you **0**, it means they agree with each other. If the combination answers you **1**, it means that they disagree. So that means asking **one time** was sufficient. Keep in mind that you don't have any information about their answers: 1. If they agree, you don't get to know what they agreed on. 2. If they don't agree, you don't get to know who of them said yes/no.

[ "Paul Wolfowitz and a lot of the other guys behind the Project for the New American Century had identified Iraq as a target for military intervention from day one of the Bush administration. As soon as those guys were in power, they were proposing invading Iraq. In order to understand why Iraq, you sort of need to understand The Project for the New American Century. America is a super-power, we all take that for granted, but twas not always thus. Our status as a powerful nation came from a combination of factors, but one big one is that we are RICH. That wealth, that prosperity, what people mean when they talk about America as being wealthy and prosperous stems from the post-war era. In the 1950s and '60s, America was the only industrial nation in the world. Well, there's probably a better way to say that: we were the only nation who emerged from WWII with 100% of our industrial capacity intact. Virtually every single other production center *in the world* had been bombed. And that took decades to recover from. So for a little while, America was the only game in town. That was nice. We were able to sell our goods everywhere in the world and that was the era when you could have an entire family and a nice house and two cars and only one member of the household was working. That's because that family member was working for a company selling its goods everywhere with almost no competition. Since the 1970s that hasn't been the case, and American prosperity has suffered. But really, the fact that it was ever so ridiculous should be remarkable, not the fact that it's less ridiculous now. A bunch of guys in the NeoConservative moment in the late 1990s got together and said \"The 20th century was great for America,\" choosing to omit the Great Depression for obvious reasons, \"How do we go about *ensuring* that the 21st Century is just as good?\" They decided the best way to ensure American prosperity was to go back to that Only Game In Town era, and turn the rest of the world into a market for US goods. Return things to the way it was in the 1950s. They formed a think tank and called it The Project For The New American Century. Their stated goal was to use American money, diplomatic power, and *military power* to turn the rest of the world into a market for American goods. This isn't a conspiracy theory, these guys didn't do anything in secret. They had a website! I went to it back in the day! They were open and upfront about all this. Bush got elected based on a few factors, but one of them was his alliance with the NeoConservative movement. He wasn't really a NeoCon, but he admired those guys. The Vulcans, they called themselves, because they liked to believe they were acting out of pure smarts and logic, with no annoying compassion or humanity in evidence. So once he's in power, he gives a lot of the guys behind the Project For The New American Century jobs in his cabinet. They immediately start looking around for ways to advance their agenda. Which...why wouldn't they? That's why Bush appointed them. Iraq--and here we get to the real answer to your question--was chosen as a target for \"regime change.\" Iraq, to the Vulcans, was perfect. On paper, it's the ideal target for these guys' plans. The guy in charge was a brutal, horrific thug. Let's just start there. If you think \"Well, I get he was a bad guy, but...,\" you maybe don't get it. It was way worse than you imagine. So it was hard for the Vulcans to imagine a world where getting rid of Saddam Hussein wasn't an axiomatic good. Iraq is a prosperous nation. Everyone seemed to think the invasion was \"about oil\" in the most naive, primitive way, but oil certainly played a factor! The oil meant the country could pay for its own reconstruction, which is huge. Iraqi's are well-educated. This isn't Afghanistan or North Korea. Iraqi's have infrastructure and universities! There are a lot of Iraqis! Again, unlike Afghanistan and North Korea, if you can get the population of Iraq out from under its dictator and with some money to spend, holy shit would that be a great **market** for someone to get into. And if those people owed you their freedom, all the better. Iraq was not a hotbed of religious nutjobbery. Unlike...Iran, in which the majority of the population really truly does think the best government is one run by the church, it wasn't *clear* that if you got rid of Saddam Hussein you'd end up with a theocratic oligarchy. In practice the reason it was secular was that the Boss Thug didn't want competition. So to the Vulcans, holy shit Iraq was perfect! You topple this dictator, spend some Iraqi oil money fixing the place up, and you're left with a rich, educated populace ready to purchase American goods. Unfortunately, the thing about these kinds of dictatorships is that it's impossible to know what will happen after you remove the guy in charge. He might be Hitler, in which case you take him out and the country thrives, or he might be Slobodan Milošević and the only reason the country was held together in the first place was because that dude used terror and brutality to do it. Certainly there were smart people arguing the latter was the case, but there was no way to prove it one way or the other. 9/11 gave the President carte blanche to invade any Middle-eastern country that could be tied to terrorism, however implausibly and at that point folks who'd been paying attention knew we'd go after Iraq, which we did." ]

[ "Yes, but evolution may not look like what you think it looks like, particularly if you're using the term \"natural selection\" - a term which even Darwin wanted to discourage as it promoted a misunderstanding of evolution. People mutate. The vast, *vast* majority of these mutations are very bad and are called \"birth defects,\" or more-or-less neutral and go unnoticed. Effectively none are radically good. Over time, these mutations cause diversification of the gene pool. \"Cross-breeding\" (mating with people who are very genetically distinct from you) also causes diversification of the gene pool; this is more likely to happen in first world countries with relatively high rates of immigration, compared to poorer countries where there is little immigration. This is evolution. It is a general change in the gene pool and a diversification of the genetic makeup of a population in a certain area. Another part of evolution is survival & reproduction rates. There is *always* a relationship between genetic makeup and death rate / reproduction rate. It may be very small, and vastly outweighed by cultural factors like wealth rather than genetic ones, but it still exists. That's kind of par for the course though - most of the time, genetic variation doesn't impact death rates *that* much. It's when there's a sudden change in environment that you notice it much more sharply. If there is a new virus which kills 10% of the children it infects, and 20% of the population has a gene which protects against it, that gene is going to wind up existing in much more of the population over time. Even outside of humans, this is how \"natural selection\" works a lot of the time - genetic diversity increases, but it doesn't matter and may not be noticed until a new pressure comes about which makes that diversity matter more, and then the diversity decreases slightly as an \"adaption\" to the environment." ]

If we switch to universal, the healthcare providers still have to get paid. So when you get a service provided to you (check up, surgery, anesthesia, etc.), the provider would then have to send that claim to 'the government' to get paid for it, and not every service would be completely covered (elective surgeries might not be covered at all or might have supplemental insurance available to cover some of it, and some procedures may have elective parts of them such as getting general anesthesia instead of local, or possibly something like going to a nicer hospital or whatever, where the government wouldn't cover 100% of your stay). In order to manage all that stuff, you still need a lot of people to process the claims, and you need to transition a lot of IT stuff (or the government contracts outside companies to keep handling that kind of stuff). So some healthcare companies may shut down, others may transition to being a government-contracted service provider, or act as a middleman to provide other services (like doing data analytics or reporting for the overall healthcare system, providing claims management stuff, etc.). In the end, you do end up laying off a lot of people, but the overall effect could be that you lower the average cost of healthcare since you no longer have middleman health insurance companies adding to your costs (both by adding cost to the provider, and by taking insurance premiums and using part of those premiums to pay for advertising and other stuff that a universal healthcare system wouldn't need, and taking part of those premiums as profit). I don't want to go into the political side of things too much, just wanted to give an idea of how some things can be affected." ]

When a bank needs cash they can go to this strip mall, find the pawnbroker that is offering the best deal and pawn their stuff for cash. And just like a pawn broker they have the option to buy it back in the future for an extra fee. This last year the pawnbrokers stopped trusting the banks, so they increased the extra fee they charge. The extra fee makes it more expensive for the bank to operate so it has to increase its fees on the loans it makes to its customers. Uncle Sam doesn't like this because they want to keep the bank's loans cheap. So, Uncle Sam opens up their own pawn shop and starts accepting stuff from banks for cash. Uncle Sam sets the fee low because they want the banks loans to stay cheap. Uncle Sam though is lending a lot of money out though, money that it would normal be putting aside to pay for the loans Uncle Sam takes out. Now Uncle Sam has a bit of savings, so everything is ok for right now because the banks should be paying Uncle Sam back eventually. However, if the banks don't buy back their stuff then Uncle Sam may not have enough money to pay his loans. It will still be ok though, because Uncle Sam can always print more money." ]

So, when you find that sweet spot where the scissors glide through, this is where the blade of the scissors is actually cutting.

The photon is absorbed, and its energy is added to the atom it collided with.

[ "They are supposed to break when hit by a bullet. The hardness of a material is not the same as its brittleness; ceramic may be brittle (it doesn't flex much before shattering) but it is a very hard material (it resists deformation). By shattering and crumbling, the force of the impact is absorbed into the material of the plate itself and spread out. Unlike a steel plate, because the ceramic can't deform, the energy from the bullet is basically absorbed and redistributed around and outward from the impact point. Think of tapping an egg against the edge of a pan to break it. The shell cracks but the yolk inside doesn't get damaged. The spiderwebbing cracks from the point of impact absorbed the force of the blow. It's also worth noting that ceramic plates aren't always standalone. The fabric of the vest also contributes to the overall protection and is usually made from something like Kevlar. The IBA (Interceptor Body Armour) that used to be used by the US military is an example of this; either the vest or the ceramic plate alone doesn't meet the military-specified protective requirements, but together they do and they're designed to be used that way. The ceramic plate absorbs the *energy* of the bullet impact and also shatters the bullet into small fragments, and then the Kevlar behind it actually catches those fragments and prevents them from continuing past the cracked plate into the body." ]

[ "The answer has a lot to do with the biochemistry of the **heme-pigment molecule** (the part of hemoglobin that carries oxygen) as well as the very sophisticated conditions within the bloodstream that change how heme behaves with respect to its binding affinities for oxygen -- in other words hemoglobin switches back and forth between \"wanting oxygen\" and \"not wanting oxygen\" depending where it is in the body. & #x200B; > The tl;dr answer is that hemoglobin actually does not like oxygen very much, but conditions around it help it bind or unbind depending on the situation. Hemoglobin binds carbon monoxide over 200x more effectively than oxygen because CO stabilizes the heme in a much more \"comfortable\" state. \\--- The real details --- At the center of the heme-complex is a single molecule of iron in the ferrous state (Fe^(2+)) which is stabilized by an array of other amino acids (protein building blocks), akin to the scaffolding of a building. This scaffolding maintains stability of the heme complex in various states, such as when it is bound to gas molecules (oxyhemoglobin, carboxyhemoglobin) or when it is unbound (plain hemoglobin). Also understand that the protein hemoglobin actually contains ***four*** heme complexes, so therefore one hemoglobin can carry 4 molecules of dioxygen/O2. In order to understand why CO displaces oxygen it helps to understand how oxygen binds in the first place. When blood containing unbound hemoglobin circulates to the lungs, **the partial pressure of oxygen (pO2)** in blood from the alveoli (lung air sacs) **is incredibly high** (about 100mmHg) and is the **main determinant that facilitates O2 binding** to the ferrous ion (Fe^(2+)) of heme, the latter of which becomes reduced to ferric (Fe^(3+)) when holding oxygen. Another important component is blood pH which is slightly less acidic in the lungs compared to other tissues -- the higher pH causes slight changes to the protein scaffolding of heme which stabilizes the Heme-Fe3+-O2 complex. There are other, less important factors at play (e.g. temperature, CO2, phosphate and something called 2,3-DPG which is beyond the scope of this ELi5 to go into). The point is, when hemoglobin is in the lungs, it **REALLY WANTS** **TO BIND OXYGEN** (and it actually does not want to get rid of it either). When blood containing oxyhemoglobin reaches body tissues, such as your heart, **the partial pressure of oxygen (pO2)** is much lower (closer to 40mmHg) and the pH is also relatively more acidic from metabolic activity. The partial pressure of CO2 (pCO2) is also higher from tissues using oxygen. All of these factors (and a few unmentioned others) shift hemoglobin's behavior to **WANT TO RELEASE OXYGEN**. This is a good thing because the body tissues want oxygen, and hemoglobin wants to get rid of it. One other factor of hemoglobin binding that relates to your question goes back to those ***four heme complexes*** per hemoglobin molecule. As one or two heme complexes bind oxygen in the right conditions, it makes the remaining 2-3 much more avid at capturing a molecule of oxygen. The reverse is also true. As oxygen leaves 1 or 2 of the heme complexes of a hemoglobin, it makes the other 2-3 filled complexes more efficient at giving up their oxygen too. I will come back to why this matters in a moment. Now that you hopefully understand oxygen behavior, can discuss carbon monoxide (CO). **The affinity of heme pigment for CO is** ***over 200x greater than that of O2***. That is one of the most important concepts here. I have explained how oxygen dynamically shifts on and off heme pigments based on the location in the body. CO does not need any assistance from blood pH, CO2, phosphate, or 2,3-DPG in order to bind to hemoglobin the way oxygen does. When CO encounters a heme complex, it binds and stabilizes the iron in the Ferric state and remains that way as carboxyhemoglobin. This is a matter of thermodynamics. The dynamic conditions that affect oxyhemoglobin don't really affect carboxyhemoglobin. When hemoglobin reaches body tissues, O2 drops off and a CO can easily sneak on. Worse still, once one heme complex binds CO it locks the other neighboring heme complexes I talked about earlier to hold their oxygen and not release it to tissues (much like the behavior of hemoglobin in the lungs). This is very problematic because any carboxyhemoglobin essentially is useless as a carrier of oxygen if it wont deliver anything to tissues. The only way to reverse this process is time, and by providing very enriched oxygen at a hospital (to raise the pO2 of blood) so that hopefully you can drown out the CO. **In summary, hemoglobin's chemistry favors treating O2 like a used hooker but treats CO like its boo.**" ]

[ "You don't need to know binary to understand this. You do need to understand two things, though: 1. Digits. Each number requires a certain number of digits. 545 requires 3 digits. 384271 requires 6 digits. Yes, computers use a different numbering system (binary) and will therefore require different numbers of digits, but the concept is the same: each number requires a certain number of digits. Also, for a certain number of digits, there is a maximum number that can be stored. For example, the biggest 3-digit number that can be stored is 999. 1000 is right out. 1. Memory addresses. Everything a computer is working on (*everything*) is stored in its memory. The way that a computer uses its memory is by using addresses. Instructions for a computer are like \"store the number 5 into address #1832\". Then later \"what was stored at address #1832 again? I need that now\". So whenever a computer is storing something in memory, or retrieving something from memory, it has to be able to figure out what address it should be using. Alright, so once you've got those two things understood, there's an unfortunate consequence of this. In order for a computer to easily/quickly figure out which address something's stored in, the address should be *fixed*. If we're doing an accounting program and we start storing the total in address #1500, it's got to stay there! Constantly moving stuff around in memory is a nightmare because you've got to have a system to keep track of where everything is, so keep all the addresses fixed. If your addresses are fixed, then that means the *sizes* (number of digits) must also be fixed. You've got to say \"okay I think my total will require a maximum of 10 digits, so let's use address #1500 through #1509\". If you later realize 10 digits wasn't enough, you're stuck. You can't make the number bigger (what if there's another number you're storing at address #1510) and you don't want to move things around, either. So you make a good guess as to what the biggest reasonable number you're going to need will be. Your addresses are fixed. The size of your numbers are fixed. For a number of a given size, there's a maximum number that can be stored there. Ultimately, that means your program's going to have limits on what kind of numbers they can store. There are systems to get around this. They're called [bignums]( URL_0 ). They have a book-keeping system to start off a number as being small, then grow it dynamically as it needs to get bigger. The book-keeping system is required because as the number gets bigger, it may need to be move to a new (free) spot in memory, so you need to always keep track of which address in memory it's moved to. Bignums aren't used all that often (usually only in specialized applications) because all the extra book-keeping makes performance quite poor." ]

[ "So, the only place where this really is the case is Europe. Europe has no predators or other large and dangerous animals; they've all been killed off over the millennia of humans living there. By comparison, North America has wolves, bears, mountain lions, moose, bison, and elk, all of which can cause pretty extensive damage to personal property, can can easily harm or kill people. In addition, there are a large variety of pest animals (like coyotes) that aren't a direct threat, but can cause all sorts of damage if they can't be driven off with firearms. In addition, Europe is pretty heavily urbanized, such that the police really aren't that far away, ever. Take, for example, Cherry and Sheridan counties in rural Nebraska, which are out in the middle of nowhere, have essentially only ranchers living in them, and (combined) are **roughly the same size as Slovenia**. So yeah, we have local police forces (and we're not talking LAPD all-black military-grade equipment police forces, but Jim-bob and his beat-up second-hand pickup police forces) who are responsible for territories the same size as entire nations. Out there, you need to be able to protect yourself, because the police may take *hours* to get to you, and that's in *good* conditions. This same part of the country averages *feet* of snow in the winter, and it only get's worse as you go further north. Finally; even Europe allows rifles with relatively few legal hangups, and rifles are what rural gun owners really want to have access to, which shouldn't be a problem given how few people are actually killed with rifles in any given year." ]

[ "I can't speak for Netflix but when it comes to computer programs where you often see this sort of thing happen while installing or downloading stuff, it's because there's really two different tasks going on inside your machine. The first task your device does is \"retrieving the file\". To do that, your computer or TV or internet-capable fridge or whatever accesses the information in the form of a file and then pulls it down into its local memory or onto longer-term storage such as its solid state drive or memory module plug-in. But that's just a file. It doesn't really do anything yet until the computing part of your device fires that file off. That second part can actually be pretty big, and it can cause a whole lot of things to happen, including some or all of the following: * it decompresses the file, because the file was artificially shrunk so it would be smaller and faster to transmit * it writes the single file into a broken down set of files somewhere else in your device's storage * it turns one of the file's components into an active computer program which begins to run * it reaches into your device's operating system to add some stuff or make changes or update files * it scans results to ensure they completed properly * it loads sections of the downloaded file into active memory, such as a picture for a loading screen ...or other things. The first 98% is step 1 where your device is grabbing the big file in the first place. But the other 2% is when it reaches near the end and is doing all that unpacking and manipulating and executing stuff. Back when the internet was slower, that second stage actually DID take 2% of the overall time (more or less) because downloads were so slow. But now with ultrafast downloads, that last 2% or so takes a lot longer in comparison to the pure download time... and so it seems longer in comparison." ]

[ "Microsoft Active Directory is a role you can install on Microsoft Windows Servers to help you create a unified rights and login infrastructure across several windows computers and applications. To explain the above a bit more in depth. You have probably a computer at home and may even be sitting in front of one as you read this. If you have a computer with windows at home you may even have it set up in such a way that it asks you for a user name and password on startup. (Many people who are the only users of their computers set it up so it skips that part and automatically logs you in). If you are a bigger organization you will have many different computers and on each one there may be different users who need to log onto the computer. As you can imagine it can be hard to keep track of all the different logins. Microsoft AD makes it so that a central computer (or several working together) have a central place for all the users and their passwords in the company. The same user logging in one computer can use the same name and password to access all computers in the company. It can also be used to login to all sorts of server applications. If the system is set up correctly a user will only need to have one username and password for everything they do in the company. This simplifies things a lot. This piece of software can be managed with a number of programs among them \"Users and computers\" which is the main one, but also the management console called \"Sites and Services\". \"Sites and services\" is not a tool anyone will need very often because you mostly use it configure different locations. Your organization may have offices in a different city with their own networks and in sites and services you configure which place has which network and how theses different sites are connected to together. It also is where you configure where the Microsoft AD servers are. Unless you are a sysadmin setting up or changing things for a branch office or similar you will never have to use this tool." ]

It remains there and available if you want to try to recover it, that is until you overwrite it with new data. This is why they say if you accidentally delete a file, to not use the computer until you can recover that file because your computer might come along and write a new file over that existing data, which effectively eliminates any trace of it." ]

When you burn methane it will look blue because its hot enough to excite the electrons on the molecules and when they settle down they give off a blue photon.

[ "When your eyes water, the tears that you see are the very same ones that keep our eyes moist and comfortable, and wash out bits of dust and debris. Those basic tear secretions are produced in the conjunctiva, the membrane that coats the entire surface of the eye. These basic secretions don’t overflow like the tears associated with emotional crying. Those tears are produced by the lachrymal gland, located in the upper, outer corner of our eyelids. Not only are they much more watery than basic tear secretions, but there are usually so many of them that they overflow and spill down your cheeks and drain through tiny ducts into your nose. So why do eyes get puffy after crying? It’s because emotional tears are more watery, they’re less salty than basic tear secretions and the tissue in your eye. So, through the process of osmosis, the water moves into the saltier ocular tissues, which makes them swell up. And then there’s all that furtive eye rubbing your “friend” does to hide his tears, which inflames his eyes even further. Still, even though it looks bad, the puffiness and irritation will eventually go away." ]

[ "Every country has only a relative handful of places where they connect their network to the rest of the world (forming the internet). For most countries, these connection points are along the coast, where fiberoptic cables (armored glass tubes) come together in large facilities for distribution throughout the country. Other countries that are landlocked have similar facilities, though I'm not sure whether they're located on the border or elsewhere. In either case, to block outside information they simply stop those signals at those facilities and prevent them from moving throughout the country (this is like what Russia is trying to do). If they want to shut down the internet within the country (such as Iran), so that people can't even communicate domestically, they turn off the internal facilities as well. What you term \"the internet\" is just information being sent through a bunch of hubs. Because it's so expensive to build, those hubs are relatively few and far between. You shut down the hubs, and nobody can send information. It's not all that different than asking \"how do you shut down the power for an entire country.\" Only there are fewer facilities providing internet than there are power stations.

The kids were encouraged to stretch the valve to make a long, narrow opening. As we all have undoubtedly experienced, this makes a high-pitched noise. But you can modify the valve a bit to make all sorts of sound qualities. If you don't stretch it too tight, and if the air pressure is not too high, then it sounds more like a standard fart. I would suspect this is how a whoopie cushion is designed. This is certainly similar to how some vocal sounds are produced. So, transfer this to our bodies, and we have an idea of factors affect the sounds of flatulence -- shape of the anal canal (brought on by body type, body position like sitting or standing, and body motion like are you running or lying down), pressure of the gas, and also wetness of the area.

Notice your rocket is still too unstable so find a better way to arrange your boosters to provide more stability. Test it again and hope for a better outcome.
