This question has hundreds of answers and entire PhD programs and world agencies dedicated to answering it. So... it's not easy to ELI5. Much of Africa has poor soil which makes growing things for profit difficult. Couple that with hundreds of years of colonization that extracted resources (and people) and you are left... |
I think it comes with expectations in the US. As someone who was born outside of the US but came to high school and college here, I can definitely say that society places a lot of importance on "self-determinance," or this whole idea that you, and only you, can define your own outcomes. In short, society here tends to ... |
There are a couple of different ways to think about this. First there are the orbitals themselves. When one solves the Schrodinger equation for the coulomb potential a set of discrete energy levels comes out. The precise values depend on the magnitude of the charges, nuclear mass, and electron mass, as well as some con... |
How do we notice most of the planets in our solar system? We observe them because light hits them and bounces back for us to see. The further away they are the harder they are to see, you get to Saturn and you can't see anything with the naked eye. Further out you need binoculars or a telescope to see them. In fact Nep... |
Have you ever rubbed your hands together and felt the warmth? That's called friction. When you erase a pencil mark, you are rubbing the rubber eraser against the paper. The friction between the rubber eraser and the paper loosens the graphite particles from the paper. The sticky rubber in the eraser grabs and holds on ... |
The President has virtually unlimited power to pardon people who have been found guilty of federal crimes. This power comes directly from the Constitution: > The President...shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment. |
Would you sculpt yourself as bald, pudgy, with a small dick even if it were these case? Or do you come out looking super Schwarzenegger? Artistic license. A vast majority of peasants would be stuck in physically demanding jobs and low-calorie diets. Only the richest members of society had the resources to live comforta... |
Brown noise helps you focus by removing auditory distractions. Its the same idea as closing your eyes to help you hear or smell better. Brown noise works better than simply blocking out sound with earplugs because our hearing become more sensitive when it's quiet. In a completely silent room where you can "hear a pin d... |
Dang it, I read an article about this just recently and now I can't find it. There are people whose job is to watch the stuff come down a conveyer belt, and they pick out what is not recyclable. They can miss things, though, which then go into the recycling, uh, machines (I should really find the article) and can mess ... |
You're paying for the cost of renting the location and paying the staff to make you it. It's the same with restaurants charging 2-3 times the price for food and drinks. |
I'm going to copy a post I just wrote for [this]( URL_1 ) thread. Cryogenic freezing of large animals and humans creates several issues: Problem #1: Saying goes freeze slow, thaw fast. A freezing rate of -1 degree per minute is ideal for most applications. The slow freezing prevents cell rupture by allowing excess pres... |
Back in the day, night vision goggles relied on vacuum tubes, specifically, photomultipliers, that were much more sensitive to light than human eyes. These tubes basically, as the name suggests, "multiply" light, making it easier for us to see. Now, the displays worked like old-school computer screens, or "tube" monito... |
[Simply not potable.]( URL_0 ) Now, let's talk about the coffee. |
This change happened during World War II, when all the other great powers devastated each other, leaving the USA (due to its geographic isolation) largely unbombed and uninvaded, with all its mighty industries intact. That, combined with vast natural resources and a very strong educational system, and a culture that we... |
Bipolar I here. I've been through psychotic mania as well as several cycles of less severe mania/depression. We know in the cases of people with bipolar disorder that there is a chemical imbalance in the brain. Your brain doesn't react emotionally the same way that other peoples' brains do. Often, regular occurrences w... |
As you sleep neurotransmitter levels change. As sleep approaches and starts melotonin is released to induce sleep and cause drowsiness. As morning approaches levels of serotonin increase. This causes feelings of well being and increases pleasure associated with tactile sensation. (Bed feels better) Literally every answ... |
The reason is because humans have evolved what basically is two systems of thinking. System 1 is the instinctual, intuitive process that all animals have. It is fast, has access to nearly all of your memories, and brings quick information based on heuristic shortcuts. Part of this is is an individual-recognizing system... |
Actually, a rolling object could be more thought of as having many more impacts, just with less force. A square object "rolling" would have four big impacts, while a bowling ball would have tons of tiny ones, which add up to the smooth rolling noise. Source: It makes sense in my head so I hope that's how it is Edit: th... |
Cringe is an empathetic response. We're social creatures and caring for each other is a part of that Pretty much everyone has some level of empathy. We get mad when we see someone else being treated unfairly. We're sad when we see something tragic happen to another. We can't help thinking about how we would respond in ... |
Which one? The common cold is a whole genus of virus, Rhinovirus, and there are lots of them. Beyond that, viruses mutate* pretty fast, and some of those mutations make a formerly effective vaccine basically worthless. Once you get a cold you're immune to that particular virus, you won't get that specific cold again, b... |
So you tried to un reverse the backwards running gif? The issue is compression I think. All formats of video have it and it can't be undone completely. So you lose some with the original and you lose some when you reverse it. And you lose some when you reverse it again. It's like putting a phrase both ways through Goog... |
I think you're confusing bacteria with parasites. Freezing kills harmful parasites like tapeworms and roundworms. The bacteria you're concerned about has nothing to do with the fish itself and everything to do with who handles it. If there is any harmful bacteria on your sushi, I'd blame your chef for not washing their... |
Valve is making money hand over fist with Steam. Half Life 3 has impossible expectations to live up to so I'm sure they'll wait until the risk doesn't outweigh the reward. Why risk messing things up right now when they're doing really well? Square long ago said they would never remake FF7. They're now remaking FF7 beca... |
The old model for most legacy airlines was to purchase planes when needed and fly them as long as possible. They are fairly stuck in that business model trying to get as much money out of aging fleets as they can. Newer budget airlines, at least the larger ones with lots of capital, make huge bulk buys. This severely l... |
Well first, you might declare bankruptcy but that doesn't mean they don't get any money. They can seize your assets, they can garnish future wages, take you to court and so on. They won't get back 100% of the money (unless they get a good court win), maybe only 30-60% of it, which in turn raises the price on all medica... |
DNA is a lot like a cookbook that your body uses to brew proteins. Proteins are themselves made from amino acids that are glued together. These proteins can have a lot of functions, some act as lego that your body uses to build structures, others function as tiny machines that your body uses to move energy and other pr... |
Cold air has a much lower capacity to hold water than warm air. Water conducts electricity, so when the air is wetter static electricity dissipates through the air more quickly. Thus, when the weather is cold, the air acts as more of an insulator and static electricity builds up more readily. |
Hiccups occur due to an irritation of the diaphragm such as eating too quickly or drinking a liquid too fast. When the diaphragm is irritated it contracts trying to pull air in while the voice box (larynx) and glottis contract and close the airway causing the "hic" part of hiccups. It can be caused by a malfunction of ... |
You have probably been lucky, and not been exposed to as many contagious people. Do you have much contact with children? There could be a lot of different reasons. Sleep, stress, exercise, age, diet, hygiene. The people in my office who get sick all the time are older, smokers, and overweight. Not an expert but the imm... |
D & D is a game of cooperative storytelling where one person sets up obstacles (a man-eating dragon, a corrupt lord, a booby-trapped labyrinth) and the others portray one or more characters who must defeat those obstacles (a fierce dwarven warrior, a smooth-talking elven archer, a crotchety old wizard). The person who ... |
Because feeling awake and alert is not the same as having more energy. In every day speech we associate that feeling with energy, but scientifically speaking it's a different thing. Look at it this way, if you're tired you feel like you're low on energy. So you go to sleep, and then when you wake up you feel like you h... |
There are really only two different concepts here. Electromagnetic waves (of which we call a small section of frequencies "visible light"), and sound waves. Electromagnetic waves can travel through empty space. Sound waves are the ripples of some type of "stuff", most familiar of which to us is air. They don't interfer... |
I'm a pre-kindergarten teacher in the United States who teaches children the alphabet, letter sounds, and how to read. This is how I was taught to teach children to read English, although there's obviously lots of other teaching methods used. For the most part, I find this process works pretty well with the vast majori... |
I actually just read about a new drug they are working with that helps grow new teeth. URL_0 |
Atoms in the universe is a Fermi problem. You take certain assumptions and then do the math. A similar question would be "how many barbers in NYC"? To solve that, you would say that there are 9 million people in NYC, half are female, so they don't use barbers, making it 4.5 million barber clients, say that men get hair... |
It seems that Panama has historically had a lot of call centers. I think the issue is that Panamanians are supposed to call a different local number instead of the regular 800 number. |
Because kernels expect to have direct access to the hardware. If you attempt to run an OS kernel as a regular program under an OS, first it will fail because the kernel expects to be loaded differently than regular OS programs (usually a kernel is loaded by a small program called a *bootloader* which is written to the ... |
Crying is a primitive way for babies to communicate "I have a problem and I need help" before they know language. As they grow up, and are capable of getting attention in other ways, or handling the issue themselves, they no longer need to cry. The other aspect is the social component. As people get older they are expe... |
You know how you can draw a triangle on a piece of paper, and the internal angles add up to 180 degrees? That only works because the paper is flat. If you were to draw a triangle on a curved surface, the internal angles *wouldn't* add up to 180 degrees except in very specific circumstances. The angles might add up to m... |
Basically, the french had a big defensive position (called the Maginot Line) along the German border. The French could have defended that position relatively easily. So the obvious way the german would have attacked was like during WW1 through Belgium where there is not as much defensive position like Bunkers. So the F... |
That's a little backwards. Global warming means all storm systems are larger, in addition to the obvious that average temperatures are very slightly higher. However, larger storm systems means that cold fronts that used to die out as they head south will go much farther, bringing freezing weather to places that infrequ... |
It seems like we have different definitions/translations for these words. From my googling, in Norway, million | milliard | billion | billiard is equivalent to English million | billion | trillion | quadrillion, which both line up with 10^6 | 10^9 | 10^12 | 10^15. This is a result of "long scale" vs "short scale"; Roma... |
It has a magnetic texture that is unique to your account. Machines read it and know which account to access. Extra sentence. |
I'm going to try my best to explain this, but it can get complicated. To understand how this works, you would need to understand how a key cylinder is made and how the key interacts with the cylinder. We'll use a 6-pin cylinder as an example. Starting with the key, as you know there are several grooves along the side o... |
It's a recent change, mostly attributed to a shift from traditional diet to high-calorie processed food. Many islands don't have enough workable land to sustain the current population with fresh food. Some have also suggested cultural support for being large plays a role. |
Most of what you taste is about how things smell. When you're eating something that's warm, you get the smells escaping from the food better as it's hotter, and the chemicals that make the smells evaporate off the food, or are drawn up in steam. For some foods this is great! Think about how good fresh bread just out th... |
Honestly, it is not worse for you. But people unfamiliar with gaming probably think it's weird and don't understand what you are doing. And the fact that it's so immersive -- like you don't want to be interrupted or talk with your Mum during the game -- may annoy her. |
An ideal gas is considered ideal due to individual molecules having no volume. This means that the gas is infinitely compressible, something not possible with a "real" gas. Eventually a real gas will become a liquid or solid, which an ideal gas won't. Additionally, ideal gasses don't have molecular interactions. That i... |
Lets say we have a battery and three node. For the TPS, we can go: * Battery, 1, 2, 3, Battery * Battery, 1, 3, 2, Battery * Battery, 2, 3, 1, Battery * Battery, 2, 1, 3, Battery * Battery, 3, 1, 2, Battery * Battery, 3, 2, 1, Battery So, you're suggesting we connect all of these patterns at the same time? Cool, lets d... |
Toilet seat: hard rigid plastic Inflatable ring: soft, pliable, squishy, flexible, air-filled donut. They're not the same at all. The only thing similar is the shape sort of. |
I remember having a course on evolution and behaviors where we were taught that children are picky with vegetables because in nature, a lot of plants are toxic and children tend to avoid them, especially since children are more fragile in case of an eventual poisoning. Moreover, a lot of green vegetables have a bitter ... |
There is no way to know they aren't. There are a lot of patents and licensing that you would have no way to check on who is using what and How. Also using a Patent doesn't mean it will look like Tesla, that is a different thing. Any number of manufacturers easily could be using various parts and concepts invented under... |
> More specifically, how is it possible to place so many mines in certain locations and areas? It isn't necessarily someone going out and carefully digging a pit and setting trip wires for every mine. Instead if you wanted to mine an area you could add a trigger delay of a few minutes and just throw buckets of mines ou... |
The communication between your cell phone and the cell tower is encrypted, but it is not end-to-end encrypted between your cell phone and the other cell phone. That means that there are three people that can read the message: you, the person who controls the cell tower, and the person you're sending the message to. If ... |
Bondholders, which means you technically can't pay the debt off early. When the US borrows money, they hold an auction, in which people give them 10,000 (usually in large multiples of $10,000) for the right to receive a few interest payments per year and $10,000 when the bond matures. These bondholders can be almost an... |
Hi! The infection itself happens a several days before you feel the first symptoms (so not in the night before you get sick). The cold and the flu are caused by different types of viruses that are mainly spread via aerosols and bodyfluids. After the infection, the virus needs some time to replicate in your body. That c... |
There are a bunch of answers here, but the reality is that this is a super touchy topic precisely because of the point you are bringing up - why would it appear that sexual assault has a different (and some would argue, one-way) standard as compared to other crimes involving alcohol. To the best of my knowledge, it is ... |
Consoles and some mobile operating systems (iOS) are "sandboxed". This means that only authorised code can run, for example in iOS you can only run apps signed by Apple from the App Store; unless you jailbreak it. Consoles are the same. On normal computer you can do whatever you want, which allows bad stuff in. With gr... |
because that's the contract between your school and your parents and you as a minor. as an 18yo, you can drop out of school, if you don't like that. |
Depends how it's drawn. Like when you draw a picture do you draw it in pencil and then paint it? Or do you draw a little bit and paint it and then draw a little bit more. I believe it was wolfenstein which was the first game to render maps in low quality and then quickly re render in higher quality as the user would lo... |
China hasn't been communist since the early 90's. it's more capitalistic than alot of western countries now. the ruling party is still named the Communist Party, but their doctrines are now mostly government oversighted capitalism. Communism really didn't work for them after a time. The people, especially those in powe... |
In the case of oil, a special set of conditions has to apply for it to be formed and preserved in the subsurface: 1. Source of organic matter (marine plankton/algae ➡️shale) 2. Deep burial (heat and pressure) ♨️⬇️ 3. Reservoir rock (eg sandstone)🍰 4. 3D Structure to trap migrating oil🗻 5. Seal to prevent it leaking o... |
When a union is formed, it cover all employees in the relevant field at the workplace. So if you work on the floor of an auto manufacturing plant and your colleagues vote to unionize, your job is now covered by agreements with the union whether you voted to unionize or not. Similarly, when a union negotiates for new em... |
One such word that could be used to describe the end of a commercial where the guy talks really fast about warnings and stuff is "disclaimer" although a disclaimer could also just be text. |
Believe it or not, a lot of space is actually pretty darn hot! In fact, there are clouds of gas/plasma that surround large galaxy clusters that can reach up to 10 million degrees Kelvin. Wow! An environment like this provides a useful example to answer your question: "Temperature" of a gas (most of space is gas/plasma)... |
usually, that is a freshness date and not a you will die if you eat it after date. If properly stored and packaged, most food doesn't have germ risks before you open it. But something like a cookie could lose its taste or firmness or whatnot. Once you open something all bets are off. You have to be really careful to ke... |
Fear is your body's way of warning you of mortal danger. Given enough 'fear', you'll produce adrenaline to help you fight or flee the danger. The way you learn to recognise something is by association. I don't need to be bitten by a shark to be afraid of it - because I've seen it (or the information has reached me some... |
No, it is not true. Sex itself can burn calories, but that's because of the moving around (physical activity), not due to orgasm. If you have vigorous sex several times per day, it will burn calories, but it's unlikely to be enough to lose a significant amount of weight. As with all of these types of questions: the ONL... |
The incentive to throttle bandwidth is 1) Generally to ensure everyone using the network has a decent speed 2) To try to limit the growth of data usage. There is only so much data that can be passed through a antenna/radio. The limits are simply physics. Typically, the higher the frequency, the more data per unit time ... |
The easiest way I can explain this, is a kevlar vest is like a cube of jello? If you smack the jello and crush it, it will break apart, but absorb the shock, if you hit it again it's just a pile of mush so it will barely stop your hand, your hand being the bullet. Because the vest can stop a bullet only if certain part... |
This sounds like a broad question, but I believe it isn't. I do not know if there is a scientific answer to this or not, so please take into account that I have chosen to compose the explanation I am about to launch into entirely by memory. Therefore, if I have any of the facts wrong and someone corrects me, it will se... |
Your body is basically shutting down (to prevent you from drinking more poison/speed recovery from the amount you already drank). The same way a computer shuts down and there's the blue screen before it turns off, you enter that "windows is shutting down" area in real life where your body is taking over for you, and yo... |
So far, every method of dealing with CO2, whether siphoning it off into space or capturing it, takes more energy and thus creates more CO2 than it gets rid of. |
Gunslinger culture is patriarchal. Doing something dishonorable was disrespectful not just to your father but all fathers. Someone who has "forgotten the face of their father" has acted dishonorably. The idea is that, at least in Roland's culture, that most sons were taught lessons by their fathers, and learned from th... |
I imagine it's like pouring vegetable oil onto a bull rider as he tries to hold on. Eventually the liquid is going to get in and help the separation take place. Probably works similarly to the garlic trick. URL_0 With the egg, the water likely creates a buffer preventing you from smooshing it too much while cracking th... |
I remembered reading about this a while back ago and had to do some googling to find his answer but /u/jiggity_gee did a pretty good ELI5 on this. Edit: This is mainly about diarrhea than regular poop. "So your bowels are like a long train track and your food is like a set of cars on the track. Transit time between Poi... |
People don't think the Earth is flat. OK, if you want more details, almost nobody thinks the Earth is flat. There are some people who say they think the Earth is flat, but it's mostly just a cry for attention, like when a little kid says he's going to hold his breath until he dies. |
Chinese airlines receive massive subsidies from their government. This allows them to operate on lower revenue. Many of the legacy US airlines are/where encumbered by self-funded pension programs that have a lot of retired former employees. More older employees who have earned raises, and therefore cost the airline mor... |
Babys do not yet possess the mental capacity to "save all data". They forget things that aren't to bad pretty fast. The same with little children. They stumble, fall, cry and 20 seconds later have forgotten they fell in the first place. For a baby its *puke, wonder what was that, forget what happened, drool* to a baby,... |
Humans are mammals, which means that we're warm blooded; our bodies constantly generate heat. We have to lose all of that heat to the environment at roughly the same rate that we produce it, or we'll overheat and die. In > 98°F weather, we can't lose heat normally, because heat can't transfer from a cooler substance (o... |
When a movie is made a committee decides what rating it gets, if it cuts certain things it may get a lighter rating. Depending on the movie/director's vision/production company, they may be aiming for a certain rating to get a different and/or bigger demographic. So for instance, if I make a slasher movie, and too much... |
Electromagnetic waves can't get through gaps in grounded metal that are smaller than half of their wavelength. The frequency of the microwaves in most microwave ovens is around 2.45GHz, so their wavelength is ~12.24cm, which means those waves get blocked by gaps in the mesh smaller than ~6.12cm. The actual gaps on a mi... |
So, let me begin by dispelling the common notion that UN resolutions carry some sort of weight of law. They do not. There is no law in international politics. Countries can and frequently do ignore UN resolutions when they feel those resolutions are in the slightest bit inconvenient. Rather than viewing a UN resolution... |
Because it's an automatic 'disgust' response. Expressions are very helpful when eating, as it enables others around you to see what you're eating, and then avoid it if you look disgusted/revolted/etc. Edit: It's an evolutionary trait - if you study other primates in the wild, they do the same thing. If I remember corre... |
It has to do with changes in the structure of the molecules that give the food its usual texture, but the specifics vary depending on the type of food in question and what it's made of. With foods that are normally moist and pliable/chewy (bread, cake, some cookies, etc.), the starches (long chains of sugars) that make... |
First, I want to say the arguments I'm about to make are ones I personally strongly disagree with so I may not support them as well as a true believer. The essential question is "what is the purpose of government?". For some, they believe that government's main goal is safety. The government's job is to prevent other a... |
Not quite. If you simplify and say that our body needs 8 hours of sleep for every 16 hours awake. If you miss out on some of that sleep then you may have some symptoms, one of them being exhausted. If you finally get a full 8 hours of sleep most of your symptoms go away. There may be some health affects still remaining... |
Cannabis have been cultivated for many different uses over the years which have resulted in a lot of genetic variation. This is not unusual with cultivated plants. Take for instance the mustard plant which not only is prominent in the spices section in the grocery store but also consists of about half the vegetable isl... |

Most US states have constitutions that would permit this, or at least have a mechanism for amending their state constitution to permit this. What's preventing it is lack of desire to raise taxes or regulations in just one state, because that might drive businesses or wealthy individuals to move to an adjacent state. By... |
Ships take on water and sand as ballast (necessary to balance the ship) and this can lead to illegal dumping or accidental leaks of said ballast. If this water or wet sand contains animals, you've just introduced a foreign species. Most of them are not actually from China. They may happen to exist in China, but they ma... |
Both are true. First the sugar provides you with energy. Then when it's used up you "crash," that is, you experience a sudden loss of energy (due partly to the excessive insulin your body put out to process all that sugar). That's why nutritionists recommend other foods that provide a more continuous supply of energy o... |
As for how, the general consensus is that he learned at least some of the language somewhere, and that it took off from there. There are multiple cases dealing with brain injuries that deal with complete changes in personality and sometimes complete changes in language, so an alter ( alternative personality) knowing a ... |
Soldiers are on the clock 24/7 365.25 days a year and don't make over time. Sure we get to go home, but if a war suddenly starts, we move. If the war lasts 5 years where we don't go home, that sucks but it's what we do. |
Most likely? Nothing. The flight would proceed as normally, with no real notable incident. But potentially? If the chance of catastrophic failure is increased by .1% ... is that really worth not switching your phone to airplane mode? It's not like you'll have service at 30,000 feet, and to be honest... why gamble? |
Python was already really popular when version 3 came out. Version 3 had a lot of non-backward-compatible changes which broke most version 2 code. A lot of Python projects aren't just one guy's Python code, they combine lots of people's Python projects together. If you maintain a Python 2 project, you can't move that p... |
Well, the US don't have such a high defence budget comparatively as people think. On average the world have a military budget of 2.3% of their GDP. The US is higher than that at 3.3%, but we talk about a 40% increase over the world average. And on of his main adversary Russia have a military budget of 5.4% of their GDP... |

Cirino can't paint, but he's grea... |
A battery isn't simply 'storing electricity' the same way a glass stores water. The electricity that flows to a battery is used to reverse a chemical reaction. The electricity is converted into chemical potential energy. This is the part that takes some time. Since it isn't a 100% efficient process, excess heat is gene... |
I'm not totally sure an atomic bomb can fit in a briefcase. The smallest nuclear weapons I'm aware of it the W54 and you would need a big back pack. It was about 10 inch by 15inch and weight about 50 pounds. I'm sure we can make a smaller one, but then you start to have problems shielding it. People will see that the g... |
