How come PC components can get fried with the static left from a simple brush, but take 220V steady current all day long? | No components in your PC get 220V except the PSU. It steps the 220V down to 12v and lower and feeds it to the various components. PC components are finely engineered to deal with low voltages in certain places. Energizing a part of a circuit board that isn't meant to be energized can cause serious damage. |
(actually 5): Depression | It's a really difficult question because there is no one-size-fits-all solution. I can only guess your exact circumstances and what you're going through. Having given it some thought, and had a look at a few sites online, this is what I think *I* would possibly do in your situation: Explain it is a depressive illness. Sometimes, people become unwell through no fault of their own or anyone else. It's not because you don't like them or they did something wrong to make you sad. Make it clear that you are not always sad; there's good days and bad days and that you're working towards making the good days outnumber the bad days - but that it does take time. You could say you're taking medicine to help you get better. Say that you appreciate their hugs/drawings/reading for you/etc. and that you love them very much. Stress that it's not possible for them to make you better and that that's a job that you and other adults are taking care of. I know it's not exactly what you're looking for but I hope that helps in some small way.I once saw a children book called "Mom can't see colors". In it the kid's mother has depression. And it is explained as a sickness where the world is always grey for her. And that it needs a lot of hard work and eventual meds to bring the color back into her life. And that the kid can help but it often won't work. ', "Sometimes my brain doesn't remember how to be happy. |
Why do all supermarkets have the same layout? | Also the check-out counters need to be by the exit so you can't steal as easily. Due to the large nature of the building, the back is reserved only for truck deliveries, and the opposite side is designated for parking, entrance, and exit. It's just the most straight forward organization. Makes it easier for randos to stop in and by something. Lots of windows for free advertising and a non-threatening atmosphere. |
Why do many biracial people such as black/white mix primarily identify as black when they are half black and half white? | People not in privilege are defined by what they are not. If you're not white, you're black, if you're not a man you're a woman. So while a white man is a person, a black man is black, a black woman is a black woman. So if you're half black/half white you're not white, so you're either half black or just black.In my experience, it really boils down to what you look like the most. Black/White mixed people will most likely identify as black because they will have characteristically black features such as darker skin and kinky hair. However, this is not true for all mixes of people. It much more common for people who are mixed Asian/White to identify as white, because they usually end up with light skin and straight hairThat's a good question. In the past, any non-whiteness pretty much made you the other. I 've recently been thinking about this myself. I just binge-watched most of Parks and Recreation, and that piqued my interest in actress [Rashida Jones.] Until reading about her on Wikipedia, I had assumed she was of some sort of Mediterranean descent, but then realized she has one black parent, [Quincy Jones,] and one white parent, [Peggy Lipton.] I'm not aware of anyone referring to her as "black," and on Parks & Rec, [there's this quote.] **Edit:** Added wikipedia linksI 've always identified myself, first and foremost, simply as "mixed". I feel it gets people to ask more questions! Since I'm not simply half white and half "_", it makes me even more of an individual. :) [half chinese, qtr Japanese, qtr white]', "As a famous comedian said in america, if you look black, you're black. It's a social convention based on how people's features are perceived. |
If you're trying to burn fat, why do you need to eat? Can't you just not eat and your body would metabolize fat and not food you recently ate? | If you've not eaten anything for a long while, you'll know that the body doesn't usually like it. Hunger pangs and generally making you fell like crap is the way things tend to go. The only way to lose weight is to ensure energy intake is lower than energy output, but not zero", 'You technically could as long as you drank water but it is extremely unhealthy ', "It's mainly because you also need other vitamins and stuff like that not just fat. Also, your body also starts living off not only fat but also your muscles.Food stimulates your metabolism. If you starve your body, it will attempt to keep mass. |
Why are blackboxes not used in motor vehicles? | They pretty much are on the newer cars, all the data from sensors on the vehicle 10 seconds prior to the collision is recorded and stored. I might be wrong on the time allowance for recording but I know there's a time frame and I know they record. Minus what's being said in the vehicle at the time. Edit: think about all the sensors if this doesn't make sense: Throttle position sensorTransmission sensors for gearing That alone can tell you the speed based on percentage of how open then throttle is and what gear you were in. Brake sensor determines how hard the brakes were pressed, if at all, prior to colliding. There's so much data available to LE after a collision based on vehicle metrics it's crazy. |
How do you establish a population/civilization with a few people and prevent inbreeding? | Just for fun.. send the original 4 with a crap ton of frozen ovum and sperm from as many different people as you want. The original four would have to be taught how to inseminate each other and pass on the knowledge to future generations. Sounds fun to me. Pass, I'll read about them on reddit instead. |
Last year, Sarah Palin went on a bus tour. Was that all it was? | No. Her bus tour was just an attempt to remain relevant, get paid for some speeches, and sell some books. Palin has no interest in running for office and won't be a factor in the upcoming elections. |
How this GIF, recently on the front page, is a visual representation of what the forth dimension looks like. | Nobody can say for sure that it is. It's just our best guess. Our brains can't perceive the fourth dimension and can't even imagine it. This is just an extrapolation based on 3D objects moving through 2D space. There's no guarantee a 4D object moving in 3D space would behave the same way. |
How does a dog know it's the owner walking up to their door as opposed to a stranger? | Dogs hearing and memory is incredible, I'm at work so I can't really cite on my phone that well, but dogs know the difference in cars coming up the driveway too, like from the sounds the tires make and engine noises it's pretty awesome, so they know if it's you or not before you even open the door |
How does lazer tattoo removal work | A tattoo needle injects rather large color particles into the layers of the skin. Those particles basically are too large for digestion of the corresponding immune cells. But over time, the particles tend to break down, mostly due to sunlight. So tattoos fade with age and lose color, intensity. A laser does the same, but faster and more precise. As far as I know, earlier lasers would only break the particles, so more sessions were needed and the immune system got much work to do. Newer lasers are able to split the particles into much smaller chunks amd attack differnt colors at various wavelenghts, meaning less sessions. Oh, just for fun: the body can't dispose/excreet these color particles. Thats why lymph nodes of deceased people with many tattoos are filled with these particles and mostly black. |
Why is it that our world map seems to be so inaccurate? | The problem is basically that it's hard to represent the globe as a flat surface without stretching and clinching the surface of it. Here's a pretty good video on the topic that I found very well explained: _URL_1_", 'Like has been said, to represent a sphere on a flat surface you need to use a certain projection method. There are a lot of methods for this and each one distorts the world map in different ways. The one that you most commonly see today, the Mercator projection, was actually designed to make seafaring easier by trying to project distances as correctly as possible. The Peters projection on the other hand was meant to show the surface area of the continents as closely as possible. |
Why as an (American) 18 year old, I can take a bullet for my country yet not enjoy a beer? | I was raised by my Grandpa and heard a lot about WW11, I don't think an 18yr old should be put in a situation to take a bullet |
Why do I cringe at the sound of styrofoam rubbing together? | A metal fork scraping on a plate. I've been known to lose it in a restaurant.I have the same problem, except at abrasive metal on metal sounds. I even have problems SEEING it happen. or THINKING about it. omg. stop. It just happened to me at the chow hall, cook dude was scrapin off the skillet thingie with the metal spatula. my god. The worst tho, is when you take a knife, and try to cut into the tines of a fork. that abrasive, jaggedy catch and grab, then release thing, really slowly, absolutely drives me to mini-convulsions. I start to get the shakes, hair stands on end, i get chills ughhh', "I don't know if anyone else has this issue but when someone pushes a marker against a piece of paper super hard, that noise just like destroys my ears, and the crine cant last up to like a minute.I have this problem without the sound about scratching newspaper if I even think about someone scratching newspaper, even accidentally, my whole body gets goosebumpsI pay extra for the eggs in the cardboard cartons because I hate the sound of Styrofoam so muchI get that feeling when I bite down on those marshmallows in Lucky CharmsOr ice scraping off of a windshield or chewing on yarn. |
The difference between Shampoo, Conditioner, Body-wash and regular soap. | Have you ever filled up a glass of water so high it overflowed? You may have noticed that the water in that glass looked like it was actually standing above the rim. Almost like a bubble. The reason the water does that is *surface tension*. Surface tension is basically the measure of how much something likes itself over something else. Water likes itself a lot. It doesn't like oil. So water will cling to itself and form a ball when it's surrounded by oil. You may be wondering why I'm talking about that when you asked about soap. Soap is this special thing called a *surfactant*. These are pretty cool because if you mix them into something like water, they lower its surface tension. This means that mixing soap into water lets you mix that water with oil. When you use a soap in the shower, what you're doing is letting the water mix with the oil on your skin and carry it away. **So how does this relate to shampoo and body wash?** Shampoos and washes contain a small amount of surfactant designed to carry oil away and down the drain. The difference between the two only really varies in the amount of surfactant and the other things they put in the soap. The other things can make a big difference, however. A shampoo will often have a lot more moisturizer in it than a body soap. It will sometimes also have different types of moisturizer. They will make your skin feel slimy but are really good at making your hair look smooth. Conditioner does not contain surfactant. It's just a moisturizer and a light acid that's designed to neutralize the slightly alkaline shampoo. |
Why can some overweight people lose weight with no excess skin, but others skin doesnt go away? | The skin can 'bounce back' if its not over stretched, or not stretched for too long. Many obese people are so fat they overstretched their skin, or were fat for so long, the elasticity was lost. |
The 'hipster' mentality. | There is just this warm, fuzzy feeling that I apparently know more and earlier, and therefore don't belong to the mundane masses I despise.It's a two part thing: The first part is having experienced something before the "mainstream" gets their hand on it. For example, if your non-internet-savvy friend walked up to you today and said "dude, I just found this site called Reddit" you 'd be halfway to being a hipster about it. The second part is making it a point to let people know that you encountered this thing before they did. So if you respond to your friend by saying "Dude, I 've been on Reddit for months" congratulations, you're a hipster. Reddit might not be the best example. Usually it involves musical artists or another art form. "I liked dubstep before Skrillex got big"Most people are fundamentally insecure to some degree. Some people derive their sense of self-worth from being "different" than others. They go to a lot of trouble to deliberately be different, and they want people to know about it. It upsets them if everyone else starts to like the same things that they like, because then they won't be different anymore.I would tell you but you wouldn't really get it. |
Why is there no cure for color blindness? | It's a deficiency of the retina, it can't be fixed with surgery unless you replace the entire thing perhaps a drug or therapy could one day cure it, the thing is that it is rare, and it is not particularly detrimental to people's well being, and thus won't get the attention of people who have the knowledge and resources to do it. They will do something else. |
Do smarter people have deeper morals, or the opposite? | The hard part about answering this question is trying to quantify morals. When you are dumb being moral is easy enough. You do what you are told is the right and good thing to do by someone you trust to know more about that sort of thing than you do. Smarter people often have to come up with their own ideas of what is right and wrong and they can be different from what everyone else thinks is right. There do not appear universally applicable concepts of good and evil and right or wrong. So morals are hard to measure. It also depends a lot on how much emphasis you have on doing the right thing for the right reason. Everyone can get this whole 'right thing to do' right by accident and everyone can get it wrong by mistake, but to really come across the right thing to do for the right reason takes someone who successfully has given the business a bit of thought. For a normal person who follows the laws being smart might not be a big advantage, but for someone who is supposed to be a leader who makes the laws being smart might be a better choice.I personally find it helpful to separate Morals from Ethics. The two topics are strongly interconnected, to the point where definitions become confused. The way I understand it, Morals are imposed from "above" , which Ethics evolved naturally from human experience, "bottom-up". For example, medical ethics were not imposed by any government: Hippocrates was a doctor and his "Hippocratic Oath" codified what was already felt by doctors in general. Ditto for legal ethics, which are by lawyers and for lawyers. Contrast that with religious morals, which are always imposed by religious leaders, who aren't always as conscientious about observing those morals themselves.There isn't much of a correlation between intelligence and morals. Someone who has never learned to read or count can be moral, and a highly educated person can have no morals whatsoever.An educated person can probably do a good job of convincing you that they are moral, but that doesn't make it true. |
When two mirrors face each other, where does the light eventually "go" so that it doesn't constantly build up? | Lasers have something like that. The laser has two mirrors facing at each other. The medium between them is active so that it will radiate light in random direction when you pump energy to it . Since the directions are random some of the emitted light is emitted so that it is trapped between the two mirrors. Now that you havelight bouncing in between the mirrors the lasing effect can happen. The light bouncing in the medium will stimulate the medium so that it emitts light that is identical to the light already bouncing in. You get more and more light bouncing between the mirrors. To get the laser beam out one of the mirrors allows some light through. Also high reflectance isn't enough. The mirrors must be placed so that the light bouncing in between them forms a standing wave. Otherwise light will leak out. Without forming standing wave light will leak out even if the mirrors have perfect 100% reflectance and they are in vacuum.There is no such thing as a perfect mirror. In your scenario, the light energy dissipates quickly through:1) Less than perfect angles of reflection.2) Absorption of light by the less than perfect glass.3) The mirror heats up slightly robbing the system of energyThe light is absorbed by the mirrors a little every bounce, turning into heat. How many reflections can occur depends on the quality of the mirror and the threshold for detecting each bounce.Alot of people here have very valid points in terms of the unlikely hood of getting it all perfect. But I would like to also add on that a mirror doesn't reflect 100% of the light going in. For example if you let of a flash inside a sphere of mirrors. Even if you got everything perfect in timing and external factors. it would only bounce around less than a second because how much light is filtered/absorbed into the material itself |
how can animals know when something is edible and when is not | You know the thing about the colors, bright colors and strange smells most often mean bag don't eat. Like the small toxic frogs in the rainforest that only have one defense which is the color if it's skin |
how you can make people hold such big secrets as Area 51 without having some leaked information? | People like money and freedom. Violate your nda with the government and you lose both. You could also be sequestered if it's a big enough project.interesting information here, specfically about "compartmentalizing information". I met a girl on tinder in San Diego who worked as a civilian in "national defense". I was so damn curious about what she knew or what she did but she wouldnt tell me a damn thing. nothing. Eventually she said "even if i did know anything, i don't know what it is". She said she only knows small parts of large programs, so she doesnt even really know what she knows. It made sense once she explained it. Basically they deprive her of info, I guess its a "need to know" thing.Nevermind Area 51, I'd like to know how they keep the events of a Game of Thrones season secret with so many people involved in the production and how easy it would be let the secret out without reprucussions. It's as if the Game of Thrones production crew are as much fans as everyone and can't wait for everyone to be shocked. |
Why when I put olives in my beer and then add a little salt do they go crazy, spin and then rise to the top? | Salt crystals are a very good surface for nucleation of carbon dioxide . When you add the salt to the drink, the salt crystals allow a good portion of the gas to form on them, which will in turn rise and attach to the first surface they touch: the olive. This will change the olive's center of balance and make it wobble/spin/etc. Once enough bubbles are attached to the olive, it will float and the process will end. |
Do the waves from electronics actually affect us in any way at all? | When it comes to electronics lets simplify things by saying there are 2 types of radiation. Non ionizing radiation which does not damage cells, and ionizing radiation which does damage cells and DNA. Your cellphone, headphones, television, stereo, blender, coffee maker, even your microwave oven, are not ionizing radiation and do not damage your DNA. Although a microwave can cook your cells, it doesn't blast their DNA strands in the way that ionizing radiation does. Now take something like an xray machine, which uses a higher energy form of electromagnetic radiation, and those are powerful enough to damage the DNA, RNA, and other parts of your cell, like invisible bullets riddling your body with holes. So in summary, unless you need a lead jacket to operate it, it's probably not going to hurt or affect you in any dangerous way. By the way, don't feel bad about your mom not understanding it. I worked in telecomm for 10 years and one of the radio engineers I worked with used to put paper towels over his lunch in the microwave because he thought it protected his food from 'radiation'. He was a radio engineer . O.o |
Why do you mix some ingredients separately first, instead of all together when baking? | I believe it also changes the chemical compound of them when you mix them together first. I saw a cool documentary on how life began. For years scientists could not put the pieces together how a particular element got there. As it turns out, they needed to mix two elements together FIRST, then that combined element mixed in with the rest. So really, we're all just cake. |
Why is it LEGAL for a cop to lie to a civilian but it is ILLEGAL for civilian to lie to a cop? | It's illegal to lie to hinder a criminal investigation. If a cop were to lie in a way that hindered a criminal investigation, that would be illegal too. So if a civilian lied to a cop and it wasn't hindering an investigation, that would be perfectly fine.If a cop lied to another cop and that did hinder an investigation, that would be illegal. It doesn't matter who says the lie, what matters is the impact of the lie. It's just that cops aren't typically in the position of lying to hinder a criminal investigation, and civilians often are. |
Reddit's REAL Explain Like I'm Five! Sponsored by reddit, inc. | Are these videos intended to be unmoderated, single point-of-view/source ELI5 answers? The nice thing about eli5 or any Reddit is that the community decides what has value and what doesn't. These videos are clearly outside of that community approach, and I hope the intent is for that difference to be clear. |
Why you need a certain graphics card to run games. | It's not the specific card that's the issue, or even the brand. The issue is computing power. Intel makes very low end cards, suitable for web browsing, office work, and watching movies. The other two GPU companies, AMD and nVidia, make more high-end cards for gaming, although they do make some weak ones, too. Your Intel card just isn't strong enough to play modern games. It's like you're trying to win a car race driving an antique junker against a bunch of F1 cars. |
Im watching Interstellar and the ship spins to create artificial gravity. How does this work? | You're thinking of a cylinder, which is a bad model--the center of a spinning cylinder does not experience centrifugal force. The space ship in Interstellar is made up of a ring, and the floor you walk on is the edge of the imaginary cylinder the ring encloses, so this problem does not arise. > Standing still would all the blood rush to your feet and you'd pass out? 1 G of force is 1 G of force, whether produced by gravity or centrifugal force. The body has evolved to circulate blood despite that downward force, which is how we survive on earth. > It doesn't seem like it would then just be the same as gravity but only slightly gravity like. It's just like gravity, so long as the ring is big enough and you remain on the edge of it . Things do get strange for small rings, with noticeably less force at your head than at your feet, and if you walk toward the center of the cylinder, toward the point that the ring is revolving around, there is less force acting on you as you get closer to that center. But this is not a problem if all the important day-to-day equipment is located in the ring structure and not the center. |
What is the motive for the ISIS terrorist group? I dont understand what makes them do what they do.. | As explained to a five year old: Essentially, they are the remnants of older terrorist organizations combined with a hodgepodge of fired military, freedom fighters, and angry civilians, who want to build their own Islamic state. They see the West as the epitome of everything that goes against Muslim teachings as well as the oppressor of their people. The whole situation, of course, is much more complicated than that -- and we could honestly go on for months about the history that's still relevant to today's situation -- but that's the gist of it.Its time to abandon all religion and work for a better humanity.Im pointing at you! Its over, there is no god,s, He would have done something or said something by now ..Atleast within the last 100 yearsCome on grow up there fairy tales |
What is that blurry sensation we get when we’re lying down and get up too quickly? | ELI5. Put a water bottle flat and stand it up. The water sits at the bottom. Your body is supposed to pump the blood at the bottom to the top, but when you stand up too fast your body can't catch up and your head doesn't have enough blood to work well because it's all stuck in your feet. |
Is there a legitimate excuse for an NBA player to not have a free throw percentage above 70 percent? | All of these answers contribute to WHY big men struggle more but OP's question was is there a LEGITIMATE excuse for why there are NBA players shoot below 70%. And the answer is still no. Muscle mass, mental state, big hands, fatigue, lack of practice, and incorrect form are all contributing factors as to why they are bad free throw shooters, but IMHO if you're being paid $5, 10, or 15 million a year, none of these are legitimate excuses. |
How can American Beauty have under 18 nudity and still be legal? | Nothing, really. Thora Birch's nudity in a film was done because it was consensual, perhaps under the proper supervision, and it wasn't meant to be considered masturbatory, like porn is. Teens, no matter what, are going to fool around with each other either on webcam or texting or any other social media. Might as well stop caring about it. |
if I smoke 1-2 packs of smokes a year would it have any significant long term effects on my health? | Really hard to quit mang. I smoked for about eight years quit for two only by substituting it for weed and smoked a bit over the summer when I quit weed and now I haven't smoked in a month but the cravings won't go away. Shit is fierce and everyday. Quit earlier before you add years onto your habit and become more dependent. |
Why is it that men and women tend to take off their shirts differently? | I would imagine most of it is socially constructed BUT if you're talking about the arm-cross-take-off that women do but most men don't it's generally due to flexibility. On the whole women are more flexible then men and that method works for them, while many men can't seem to get the motion down correctly due to lack of flexibility in their shoulders. Add to that the x-method also makes your body smaller, something that is the anti-thesis to being a macho-male where emphasizing your should size is a must. Finally tighter clothes seem to be easier to take off with the x-method. Personally if I have a wetsuit shirt on that's how I have to take it off, where as a loose shirt can be taken off any old method. Women tend to wear tighter clothes then men. |
How are housing prices above pre-recession levels, yet home ownership remains at a five-decade low? | If it's anything like here in Vegas, people are just mentally scared and their credit is shot still. Buying a home with a mortgage is almost 30% cheaper on average than renting a home of similar value. But many people can't qualify and the ones that can are still have the mentality that it is more expensive to buy a home, so they feel they can't afford it without doing the research. |
Why are people so afraid of genetically modified food when study after study says it's safe? | I'm concerned primarily about Monsanto. I think they are a bad operator and need to be broken up. Especially their paramilitary corporation and food divisions. |
How are very accurate values of Pi calculated? | Archimedes created a method in which you start with 2 shapes , one drawn on the inside of the circle so its points touch the edge, the other drawn outside of the circle so its edges touch the sides of the circle. Lets use squares as an example . So you have a circle with a square on the inside and another on the outside. You can find the lengths of the edges of the squares, and the average of these two numbers will be close to the circumference of the square. Knowing that Pi is simply the ratio of circumference to diameter, you can solve for Pi. This will give you a very rough estimate. You can improve the accuracy of this by increasing the number of sides of the shapes you draw inside and outside of the circle. For example, we could double the number of sides, and then we'd have an octagon instead of a square, which fits a circle a lot better. As you add more and more sides the numbers begin to converge to a single value. It takes a polygon with about 96 sides to get a value of Pi accurate to 5 decimal places. There is a very interesting book on this subject, [A History of Pi] |
Why is Nuclear Fusion "always 30 years away"? | The core problem is that the physics are reasonably easy, the engineering however is not. So physicists proclaim a new shiny theory on how you could build a machine to generate energy from fusion and then just assume that in 30 years time some engineer will have figured out how to actually put that plan into practice. But as it turns out, there are always unforeseen problems and building those things is far more complicated then was first imagined. Also funding is a big issue, because you generally don't get 1 billion dollars for an idea that just might work or not. So a lot of reactor designs that might work, have never really been tried to be put into practice. And of course ones those 30 years have passed and a machine actually build, it turns out that maybe it wasn't quite the right way to go and other routes might provide more fruitful results. |
why is prostitution illegal if it's two consenting adults? | My answer: it's not illegal everywhere. I know that in New Zealand, for example, the only restrictions in terms of prostitution are that local governments can prevent brothels from opening in certain areas. This way prostitutes are paying taxes , and also are not afraid to approach the police if someone commits a crime against them. |
Why there so much language diversity in Papua New Guinea and India, but not in China or France | Spoken languages in China has hundreds of languages. The main ones are mandarin with hundreds of different accents. There are at least 50 others like Shanghai-ese and Cantonese which is a different language entirely. Not to mention areas of the country where other country's languages that are spoke natively like Korean, Japanese, Vietnamese, Russian. And the northwest and way Western parts of the country are mostly populated by folk that are more akin to Middle East than East Asian. The native Uyghur speak their own language.Originally there were millions of languages. As empires expand they find they work better when they have a common language. Indonesia is a land of hundreds of islands, including Papua, and every island has one or more languages. But the country overall, including Papua, use Bahasa Indoniesia as the official language. |
How I can get a virus by simply visiting a website? | If a site you trust and visit often causes a virus alert, I usually take that as a sign of spyware. Spyware tends to hijack your browser, and make it load extra sites in addition to the one you think you're loading. But no one else mentioned it, so maybe I'm wrong? |
Why is everyone against Qatar hosting the World Cup? | why doesn't someone just start a company like FIFA that only sucks half as much balls? That way all the players choose that new, kinda sucks league and FIFA can go fuck itself |
How Urine Color Is a Sign of Dehydration? | A lot of people are missing one of the main points here. While the kidneys do help get rid of waste, they are equally important for maintaining proper intravascular fluid status . This is done mainly through excretion of electrolytes by blood filtration via the glomerulus in the functional units of the kidneys which are called nephrons. If pressure sensing cells detect that there is too much intravascular fluid, the nephrons will excrete more electrolytes which causes more water to follow. On the other hand, if pressure sensing cells detect too low of pressure, the nephrons will cause the electrolytes to be reabsorbed into the blood stream to prevent the water loss and subsequent further drops in blood pressure. So the color of the urine comes into play due to concentration of waste products which is primarily urea and smaller amounts of creatinine, toxins, etc If you are dehydrated you have less water in your IV space, which could be due to lack of water intake or exacerbated by other fluid losses such as sweating, vomiting, or diarrhea among other causes. With low IV fluid status, the kidneys will do all they can do delay urination and keep trying to reabsorb more water and electrolytes to maintain blood pressure while the waste products accumulate in the bladder in small amounts of fluid . When you are properly hydrated, you will have more than enough fluid to maintain blood pressure thus the kidneys will excrete more electrolytes and subsequent water to keep proper pressure. You see less color because there is now so much water compared to waste . This is a tad simplified for brevity's sake, so if something is not clear I'd be glad to try to help.

Why are most people, especially military taught to aim "center mass" when there's such a prevalence of body armor in a modern conflict? | Because you're more likely to hit your target since that's the largest part that moves the least. Hitting someone with armor is more effective than missing someone that's naked", 'At the moment, guns are better than body armour. A 7mm round will smash through ceramic bodyplate. Also, if you shoot somebody in the face, they are dead. One person off the battlefield. But if you shoot somebody in the chest, and they get a lump of steel and shards of their cuirass lodged in their torso they will need two people to carry them off. Three people off the battlefield.Either way, getting hit while wearing SAPI plates will take you down and out of the gun battle momentarily. Bullets might not penetrate but they don't just bounce off either. They will make you hurt. |
why is being "cisgender" bad? | Can you give a source of this actually happening? I know the feminist community can be ridiculous sometimes, but I've never seen them say that being cis is actually *bad*. You may be taking things out of context. They like to talk about cis-privilege. |
Why do blankets that have been stored for a long period smell weird? Stored in closets, boxes, etc | Not an answer, but did you mean that thrifty odour? Like the same odour you can smell from walking in a thrift store? Cus I've been wondering the same thing |
Why is gravity measured as 9.8 m/s^2 | I think it's probably understood that velocity is measured in distance over time. You can think of this as a change in location over time. Which units of distance and time isn't important, but the metric system would have us use meters and seconds. How many meters an object moves per second. Acceleration is the measure of the change in velocity over time. Since velocity is measured in distance divided by time , acceleration is the change in distance divided by time over time.Speed in measured in distance/time. Mph or km/h or m/s. Acceleration is usually measured in a time needed to reach speed . But for gravity the more scientific way is to use SI unit of speed, m/s. Divide that on time unit and you have acceleration.When something is falling toward the ground on planet earth, it's speed will increase by 9.8 m/s every second. This gives the object an acceleration of 9.8 ms^-2. What causes the acceleration is gravitational force. Thus gravity on earth is measures as 9.8 ms^-2. |
What effect will the cessation of Saturday USPS mail delivery have? | Netflix power-watchers will have to significantly alter their habits. For those who live near processing facilities, there's a two-day turnaround period. For example, if I mail a movie on Monday, they receive it and mail another disc on Tuesday, and I receive the new disc on Wednesday. If I watch the disc on Wednesday, I can repeat this 3-day cycle twice per week. Mail a disc Thursday, get new disc Saturday, watch and mail on Monday. If I stick to this schedule, I watch 8 discs in 4 weeks. With only 5 days of delivery, instead of 6, I can mail a disc on Monday, get a disc on Wednesday, mail a disc on Thursday, get a disc on Monday, mail a disc on Tuesday, get a disc on Thursday, etc. In 4 weeks, I can only watch 6 or 7 discs, and even fewer if I want to guarantee weekend viewings. tl:dr my life is netflix |
How is it decided what pictures are featured in wikipedia articles for things like "Human" or "Cat"? | Personally, I like the Thai couple as the representative picture for humans. Most humans live in East Asia, and most humans live a relatively simple pastoral lifestyle. The picture illustrates nicely what a typical human looks like and lives like. I also really like how dispassionately that article is written, and its terse scientific tone. It is almost like an alien biologist was making a survey of Earth's sole sentient species. |
Why do big cases like Dylan Roof's take so long to go to trial? | This is going to be a death penalty case. Part of that will involve establishing the motive for the crime, and not just that he did it. That takes a lot of work gathering evidence, because most people won't just let you inside their head.There are also sometimes even physical issues. The trial for The Dark Knight Rises attack was expected to be so heavily attended that the Arapahoe County courthouse accelerated plans to expand their parking lot |
Why do I have to preheat the oven? | If I'm making a cake or cookies, I preheat. Cakes can be fiddly and cookies are in for such a short time. If I'm making a savory item , I don't worry as much about whether the oven is all the way warmed up. |
Why do most Americans not use a kettle while the rest of the world does? | ######**Sweet Southern Tea** * Bring 1qt water to boil in a 1.5qt pot* Remove from burner * Add 2 family sized tea bags and steep 15 minutes * Remove tea bags and add .5 cup of sugar; stir until sugar is dissolved * Pour in a 2 qt pitcher and fill will cold water * Refrigerate and serve with ice Why would I clutter up my kitchen with a kettle when I don't need it? |
Why North Korea having a tantrum results in them getting food aid? | They may not directly ask for help, but they definitely need it. The average NKorean probably lives in famine like conditions. Sending food gives NK part of what it wants, and they pretend it happened because we are scared of them. That doesn't mean we should take their threats lightly, though. Edit: This is the 5th time in a row that I've commented only to realize someone else has already said what I wanted to say. |
Why don't people use glasses to give them better than 20-20 vision? | 20X20 is just average, not perfect. The reason people don't do this, other than lack of necessity, is that the muscles controlling the lens of the eye aren't strong enough to compensate. If you could see an object clearly 100m away with 20X20 vision, but used glasses to see it clearly 200m away, your lens would have to compensate even more for close up objects, and it just can't do that, except in people with naturally better than 20X20 vision, and even then not always; some of them are long sighted.It definitely happens. I only need a very minor prescription , but my glasses get me 20/10 vision. |
How do those checkbox "I'm not a robot" capchas work? | When AI finally became aware it started posting questions on ELI5 Don't give it the answer!", 'Silly robot, you think we will explain it to you so you can beat the test. Not this time!!!`It also watches your mouse movements, clicks and **keystrokes** ` Erm, there keylogging? how much of that data is sent from client side to server side?', "It doesn't require passing a captcha to make a reddit username, you guys could be giving a a robot the answers he needs |
Why does giving birth hurt, even though it harms reproduction? why was it not removed through natural selection? | Natural selection doesn't care if it hurts like shitting hot lava. Natural selection only cares that both mother and baby survive often enough that the baby's big-ass head is a net advantage in replicating those genes. Bear in mind, the human ginormous freaking head is, evolutionarily speaking, kind of a recent thing. Go back a few million years, or look at basically any other category of mammals and you'll find way smaller heads relative to the size of the birth canal. But somewhere along the line, our branch of the tree of life stumbled upon the fact that bigger brains turn out to be a survival advantage, and we've pushed that trait for thousands upon thousands of generations, until we've ended up with the huge freakin' melons we've got today. Yes, this puts stress on the rest of the female reproductive system, which has had to evolve to keep up, which is why humans have such large openings in our pelvises. It's all about those damn baby heads. But again, evolution doesn't give a shit if it hurts. It only matters if the baby survives, and the mother survives to take care of it. So from a natural selection standpoint, the birth canal only has to adapt enough to bring survival rates to the point where that big head is a net advantage. Nothing says the birth canal has to evolve to the point where pushing 'em out is *comfortable*. |
Why does the USA spend so much money on her military, compared to other countries? $682Bn compared to $166Bn by China, the second biggest spender | There are quite a few reasons, and I'll try to be as politics free as possible: -We are isolated from the parts of the world that are strategically important to us, like Europe, Asia, and the Middle East. If we want to be able to intervene militarily there, that means a pretty capable navy and air force, neither of which are cheap. This is a bigger factor than I think a lot of people realize. -As much as we like to say we aren't the world's policeman, we kind of are. Most major conflicts in the world will wind up involving us some way or another. We also patrol the seas and are often the first to have assets available during disasters. To be anywhere, you have to be everywhere. -Shit is just more expensive in the US compared to China. From labor and raw goods to compliance with regulations. -We use the military as a way to indirectly subsidize aerospace and other industries. -We also subsidize our allies. Some of those countries can spend less on their own militaries because they just buy from us. That allows them to defend themselves more economically while strengthening the ties between us. The Russians do the same. That R & D ain't cheap though. -Defense contractors have good lobbyists and lawmakers like military projects as they drive dollars to their districts and make them look tough. -We tend to be a bit fearful of the world and a large and advanced military makes us feel safer. -We like to be, or think we can spend our way into being, the best at things. So really it is a combination of factors. |
What is the causing the drought in the Western United States; how bad is it exactly? | There is a massive ridge of high pressure off the coast. Think of it as being like a mountain range blocking all the storms and rainfall from crossing it, except instead of being made of land it's made of a column of air. While these aren't terribly uncommon, this one in particular has proven to be remarkably resilient and shows no signs of letting up. As to why it's formed and won't go away? We're not really sure. There is *some* speculation that it might be related to increasing ocean temperatures, but nothing definitive. |
How do they make the sex scenes on shows like Game of Thrones look so real? [NSFW] | It's fake. I know it seems impossible but it is. Even kissing is faked quite often.They have skincolored underwear or socks on their genitals and things like that. Clever camera angles.HBU needs to make a show about a detective that smells crime. Full Penetration will be the twist. There is always a twistSO all in all they are just dry humping each other? how does he not pop a stiffy.cock sock or no, I'd prolly nut just grinding on some of them girls in GoT. |
The history of Canada. Why were the Canadian provinces not involved in the American war of independence, and how did Canada come to be a separate country? | The US wanted the Canadian provinces to join the US war for Independence. In the Articles of Confederation, which was the governing document for the country before the Constitution, it specifically stated that Canada could join the Union. Early in the Revolutionary War, US forces attempted to invade Canada in Quebec but were defeated. At the Treaty of Paris, which ended the Revolutionary War, US negotiators wanted to add Canada to the country but were refused. The short of it was Canada was a loyalist stronghold and didn't become fully independent until 1984. ref: _URL_0_ |
what is a VPN? How does it work? And how can I get one for my Mac? | With a VPN, your computer has an encrypted connection to a VPN server. Since it's encrypted, it can't be intercepted by anyone other than the VPN provider. That VPN server then forwards your request onto the public internet. A third party spying on the connection will only see the connection from the VPN to the website - they cannot read the connection between the you and the VPN.A VPN or a virtual private network is a way for a PC to contact a public network as if it were a private network. Basically when using a VPN it is harder to intercept your data because "virtually" you are connecting to said public network, privately. A good free VPN you can you is HotspotSheild or OpenVPN both are free and pretty reliableYour traffic is redirected from your isp's servers to the vpn host's servers in another nation so government authorities cannot access the data. Your metadata will show up as "user has connected to *insert ip* instead of the actual site/things you were doing. |
So, what exactly am I supposed to DO about climate change? | You can always try complaining or self-loathing. I'm not entirely sure if it offsets your carbon output, but it seems to be a popular option. |
Is there a difference between consuming 1500 calories in a day vs. consuming 2000 and burning 500? | An add-on question for anyone who cares to answer. Something I've noticed is that, when I eat a lot in a given day, and don't move much, I take an absolutely *massive* dump. Huge amounts of matter are literally shit away down the toilet. When I eat a lot, but *do* move a lot , I take a much smaller dump afterwards. In other words, the amount of waste expelled by my body correlates with the overall caloric needs for that day, seeming to give a natural balance. I'm also one of those eternally skinny guys who never seems to gain excess weight. I always assumed it would slow down or something when I get older, but it never has, even though now I'm in my early 30s. Might this be part of the reason why? |
What is the significance of haikus? | > What I don't get is what's so special about this particular arrangement. How did something so random and mundane ever become popularized? [It's Memetic] - Basically, it's one of the main memes of poetry, right next to 'Rhyme the last word' It is short, easy to learn, easy to replicate, easily recognizable, and not limited by language or skill. Therefore, the idea/concept/instance of Haikus seem to self-replicate and spread like wildfire. It is successful for all the same reasons that the blocky 'S' is so popular across . basically all children. Once you've seen it once, had it explained once, you can replicate it and show it to others. Because humans like patterns so much, and humans like familiarity and forming bonds with other humans, and like being GOOD at things, when something is easy to learn, replicate, recognize, and share .. humans fuckin' love that shit. It's also why songs with repetitive refrains and easy-to-remember choruses become so popular. Also I'm pretty sure Haikus are taught in writing class nowadays, and again - super easy to learn and remember, so it becomes a shared cultural experience, even outside of Japan. Humans like patterns Even poetry can meme also, it is fun |
When receiving an electric shock from a large current it "may make it impossible for a shock victim to let go of an energized object". Why is this? | It depends on the type of current, the frequency, and the voltage. Our bodies use electrical conduction to control our muscles. Think of them like coiled springs which simply need a small amount of activation energy in order to release their energy. If you apply a high enough external voltage, and it alternates at the right frequency, it can trick the bodies muscles into flexing involuntarily. When the muscles in your forearm contract the motion this forms is your fingers pulling in towards your palm in a grasping motion. If you are electrocuted then the electricity moving through your body may drown out the bodies own nerve impulses making you unable to control your muscles, which are now gripping whatever it is you touched very strongly. In order to trigger a muscle the electricity must be high voltage and it must alternate or pulse. It's the rising and falling edges of the voltage change that triggers the muscle response. Low voltage won't trigger the muscles, even if the amperage is enough to cause burns, and direct current tends to just burn you rather than cause involuntary contractions. You don't need much amperage to make a muscle move either, just high voltage. There is enough energy in a AA battery to make both your arms jump involuntarily if the voltage is stepped up. When I was a kid I took a clock radio apart and used the step down transformer that converted the 120vAC to 9vAC except I used it backwards by connecting a battery to the 9v side, which stepped the voltage up on the 120v side. Using a 1.5v AA battery this transformer had enough step up in voltage to allow 15 students to hold hands in a circle with the 2 at the ends holding each end of the 120v side an one tap of that battery made 15 peoples arms jump involuntarily.Either the current, AC, is putting your muscles into spasms, or it is causing your muscles to clench, DC. Either way you no longer control your muscles. It does not take a large current to kill you. Just a few, 15, milliamp through the heart will do it. |
how spiders start their webs across large gaps like between trees and across footpaths | I've watch them abseil down from a tree branch with a web line, walk around the edge of the pool, climb the house at the other side and then pull the web tight stringing a line from the tree over the pool to the house. |
Why do people with depression have such a difficult time making decisions? | One of the most important parts of making any decision is your brain trying to predict the future and evaluate how different situations will have different results and how you feel about those different results. Depression saps your ability to accurately judge how these possible results will actually feel, particularly if they will be a positive experience. There are times when depressed that you enjoy yourself doing something, at least for a time, but almost unilaterally you wouldn't be able to predict before hand that you would enjoy it. As a result, when you subconsciously go through your predictions all you see is neutral or negative results and have very little incentive to actually choose. When everything seems like it is going to result in either blah or bad, why even choose? It's much easier to just take the path of least resistance.It is quite complicated from a neurologic standpoint. In a depressive state multiple areas of the brain are affected with some areas having increased metabolic activity and others less. Decision making centers are often included in this decreased activity, as well as areas affecting motivation. _URL_0_ |
How did chicken become the universal meat that almost every single culture in the world eats? | Because chickens are easy. They don't require much room, they don't eat much, they grow quickly, and they breed prodigiously. Add to that the fact that raising chickens means a steady supply of eggs, and you have the perfect domesticated animal.Pork is the most consumed meat in the world so chicken is only the most widespread because of religious dietary reasons.Chickens are easy to raise and won't scratch your eyes out like wild mammals with claws. Cows are huge, and fish need lots of water. I always wonder why the natural way of things was to have dogs as pets instead of food as they're easy to train and control. I guess we understand them better than chickens, but chickens are pretty smart, too. |
How can we be expected to follow the law? | Depends what country you're in. In the UK it's all accessible online at the handily titled _URL_2_, and they even update the records to show amendments when an old act is changed by future acts , rather than just statically showing the law as it was written when it was initially passed. Places like America and Australia are a bit more fiddly as you have layers of Federal Law, with State Law sitting alongside it, so there are no single, central repositories of law.So in some sense, your question's premise is false. Many states and nations host their laws online. You can read US Federal law here: _URL_4_ and you can google "laws of X" for whatever jurisdiction you care about. Before reading that it helps to understand the principles behind criminal law, which you can get from this [webcomic drawn by a former prosecutor] However in some sense you are right because the quantity of laws and regulations is large enough that you don't have time to know all of the law.It should be at your Local Library. Quit being lazy.You kids and your downloads. Get off my Lawn. That's Trespassing. :) As a Philosophical Question, the answer is: no one follows all the laws. Those of you going one mile per hour over the speed limit are criminals and should be put to death. |
Why have no plane passenger parachutes been invented? | Do we really need to answer this question over and over again? It's not cost effective It weights a lot It would tear plane apart if deployed in full speed Most of the crashes are during take off/landing |
If humans continue to cut down forests, will there eventually be a point where oxygen produced can't compensate for oxygen being used? | OP I recommend you watch a video by vSauce on YouTube titled something like 'what would happen if the sun was to dissappear'. Michael Stevens discusses the events subsequent to the sun just hypothetically instantly disappearing. He discusses that after a certain amount of time plants would no longer be able to survive at all after their plan B for no photosynthesis fails too. He discusses what happens with the air we breathe. I remember him saying something to the effect of that we would have enough air with enough oxygen in for a long long while. I can't remember the exact number though sorry. I would link the video but I'm on my phone. |
How is water 'purified' naturally (where it is safe to drink)? | Everybody here so far is right to an extent. I'd just like to add some soil interface and groundwater interactions for completeness and wonder sake. First, of course is soil interface. Here water is drank by plants, animals, and bacteria, used to perform chemical reactions and wash waste materials from their bodies, and returned to the soil, and often taken back up with the waste matter as a resource in the body of another living thing. What washes through the entire soil profile often ends up acidic with all the carbonic acid it has picked up from the soil profile. This acidity greatly assists water's capability to remove heavy metals from the soil profile where they a most detrimental to living systems. Once water pools on top of a clay lense, a water table, or other obstruction it no longer has access to oxygen and the concentration of the oxidant necessary to keep hydrogen and thus the heavy metals in solution decreases. Deep in the water table these metals can be deposited in areas that create basic conditions. Thus by the time water comes out of a deep, cold spring it has not only filtered through various forms of living creatures, been made unlivable and mineral rich by acidification and removed metals and other solutes through buffering the groundwater table in general, it has also squeezed through miles of oxygen free sand, silt, clay, limestone and other mazes before arriving enriched with the good minerals that a healthy mammal needs to survive. |
how does capitalism directly impact the environment | it doesn't. However it does impact it indirectly. Capitalism makes companies go for the most profit. If you go for the most profit you try to cut as most costs as you can. They are more concerned about profits than the environment. |
What are the criticisms made by the Chinese government against democracy and to what extent are they correct? | It's a spectrum. I just spent 3mo in China doing business. The feeling from most of the educated businesspeople I know was: we are transitioning to a democracy, but right now more central control is required for growth. Point being that democracy works best in developed countries, while developing countries turn into a mess under a democratic system. I think there have been many historical examples to this point. |
why scientific theories (evolution, gravity, global warming, etc) are more universally supported than scientific laws (mainly laws of relativity)? | As I understand, 'law' is just an old concept: people thought that they're discovering laws of nature which are universal and absolute. Later scientists found out that what they had were, in fact, imprecise, approximate models of certain phenomena. So now they recognize that they work with such models which have limited applicability , and so now they call their work 'theories'. So word 'law' is used to name some models, usually equations, for historic reasons. But usually modern scientists call their equations 'equations', not 'laws'. |
Why do I read stories every few months about researchers developing amazing new battery technology but batteries still suck after so many years? | They don't suck bro. My phone has the computing power of the computer I used to play HL2, minus a GPU, and I use it all day as a camera, browser, phone, game device, storage, and a business ledger and don't have to plug it in til I get home. |
Why have wages been stagnant since the 60s, yet housing costs have doubled and college costs have trippled? | There is nothing compelling corporations to give workers more money now, whereas before the 60's you had a masive labour movement. All major increases in things like minimum wage, etc. are gained by the workers, not just given to them.Wages were as high as they were in the 50s and 60s because the rest of the world was either rebuilding from being destroyed in WWII, or just pre-industrial. That left US producers and workers in a very advantageous position of being able to command high prices. But, once Europe and Japan rebuilt, and other countries started to develop, the US lost that productive hegemony. Meanwhile, American subsidies for loans for higher education and homeownership induced many more people to enter those markets, without a corresponding increase in supply, raising those pricesShort answer: Downward pressure on wages due to globalization. Cheap easy money for housing, in addition to tax subsidy. Same with College education.The government began subsidizing housing and college. General purchasing power for those items, therefore went up, allowing housing values and college costs to climb. The more assistance government provides, the more the values will inflate because more people have access to that thing. Simple economic reaction. It's an important downside and side effect of any government intervention in an otherwise private sector market. It works very well for those who receive a huge portion of the subsidies. It, unfortunately, causes those expenses to become greater for everyone else.Back in the 60's almost everything Americans bought was made in America. Cars, TVs, Radios, etc. That's when trickle down actually worked. When companies moved overseas the money trickled down there. This what my comeback is when conservatives say "look at JFKs tax cuts, they worked". |
Why is tile always cold? | Okay, so you know how sometimes you are really cold, and you want to get warm really fast? That's how tile feels all the time. Your feet are like the best blanket in the world to it. It wants to take in all the heat from your feet very quickly, which makes it feel cold. |
Why was The Greenhouse Effect taught to me as fact but now up for such debate? | Just like another has posted, it's only controversial because people have interests. Those interests can either be money or the well being of the planet. There are also slight possibilities that some of those advocating for the reduction of greenhouse gasses also being the one's likely to profit from the conversion to renewable energy, but given that energy companies are already buying up or moving part of their operations to renewables shows that this isn't the majority. I don't think that there's any real confusion or debate going on with climatologists or geologists or any scientist related to this subject that actually indicates contention. What I mean to say is that those without skin in the game are all answering the same way and most of their academic findings back up what people have been saying for decades. The contention comes from the people who stand to lose money that try hard to prevent that. I really don't think there's been a time in recent past where there's ever been a large movement of academics in this area to flip their opinion to something other than greenhouse gasses causing an increase in temperature. A quick googling shows things like [this] where nasa says that greenhouse gas does increase temp, but I can't take the time right now to find where I've read that the rapid increase in combustion engine use has created a lot of carbon dioxide that is increasing our temperature. I don't think there's much debate or contention about that either. We are burning more things and producing a lot more carbon dioxide than in our history if memory serves. |
Why are states like California and Colorado allowed to legalize marijuana and have medical marijuana dispensaries if that contradicts federal law? | There's a big controversy over this. The federal government claims that because they decided that marijuana is bad that means that the states can't reverse that. However the federal government does not have the constitutional authority to make marijuana illegal. The constitution lists things that the federal government is allowed to control, and everything else belongs to the states. Over the past two hundred years that division has been eroded with the feds ignoring that part of our founding and continue expanding their power. |
Why do big poker tournaments still use physical chips? | Playing with the chips gives the players something to do with their hands. Anyways, it's just part of the tradition. I bet if they tried to take them away, a lot of the players would revolt. It's useful to have giant stacks of chips in front of you to try to intimidate players. It's satisfying to pull the big pile of chips over to your spot after a big win. And it's also more entertaining for the people watching, which is important.There is a psychological aspect to chips, and if chips were for some reason be replaced with some electronic system, play styles would definitely be altered accordingly.Players will have used chips in all the games they've played leading up to the big ones. All the games at home and in small pubs, clubs and hotels where it's not practical to use computers because the money isn't there and because the games are self-dealt and half the old guys at the table can barely use an ATM card never mind manage everyone's bets and blinds on a tablet, laptop or big screen. Players are used to chips. Used to knowing what they have, which columns of chip to push and how quickly maybe for psychological effect or because it feels good. To then do a switcharoo at the most important time ie the biggest games for no other reason than score can also be kept on a computer doesn't make any sense.Chips work. They're cheap, versatile, reliable, tangible, easy to see, use and understand. Bets are placed with a physical action and so are less likely to be misinterpreted or require verbal confirmation. It ain't broke so don't fix it. Chess could also be played on a screen but real boards and pieces are used for similar reasons, mainly, it ain't broke. |
How is Netflix making money from House of Cards? | They hope that people will sign up for an account in order to watch the show because that's the only legal way to see it. |
Why does it seem that the US is further behind in teaching other languages in education? | From my perspective as an american living abroad, while yes English is taught in schools, if you stop a random person on the street and ask them how they learned english, the most common reply is through Cartoons/Movies/TC Shows/Music etc. etc. This is accented by schooling, however the impetus to learn is often the largely English media. Being from the US, I never had this problem where there was some new cool movie or TV show I wanted to see really bad but I couldn't understand because it was not in English. |
Why are certain fruits, such as grapefruit and cranberries, dangerous to eat whilst taking blood thinning medication like Warfarin? | I remember listening to Michael Savage around 2002ish and he started in on a rant about this. Something about since the doctors said not eat grape fruit with his medicine that meant he could just skip the medicine and eat the grapefruit for the same effect. That's when I stopped listening to Michael Savage. |
The difference between a Republic and a Democracy. | All that is really unarguable is that 'republic' comes from Latin and 'democracy' comes from Greek. In English usage, Republic means a country with an elected head of state instead of a monarch. A democracy means that the country is run by elected politicians, whether the head of state is elected or not. |
What did Sony achieve by cancelling "The Interview"? | Overall I think that this decision will actually work out in their favor. honestly, who thought that this movie would do well? i didn't. This decision is the best advertising. Tell the public they can't have it then a week or so later release it and have twice the estimated profits on opening day. |
from my 5 year old. why can't we feel the earth spinning? | It looks like most comments here address Earth moving, not _spinning_. Spinning is _always_ an accelerated movement, so 'inertia' is not applicable here. Actually, the effect from Earth spinning can be easily detected, but it's just too subtle for humans to notice. See: [Foucault pendulum]. Basically, Earth is spinning relatively slowly, so we don't notice. |
Why do we instinctively cover our mouths when we witness something horrific happen? | It happens if we see or hear something terrible, or don't want to say something terrible, and stops us from screaming or making noise and thereby drawing attention to ourselves. This gag response is a remnant from times when danger could have been attracted by noise. For example, imagine the response of an early human to his friend being eaten by a lion.I think it's partly learned from others, partly the instinct to self-soothe by touching the face, and partly the desire to hide strong reactions; most of us learn, on some level, that showing strong reactions not only transfers our reaction to others, but also leaves us vulnerable if others feel differently. Covering those reactions is a pretty sensible thing, in larger social groups that need to manage emotional transfer due to their size and density , but smaller social groups, like rural dwellers, often do not learn those patterns, as they aren't as important; hence the country bumpkin's mouth hanging open. Edit: this is "original research". I like to read and think a lot about this stuff, but there are no letters after my name.Probably because we tend to open our mouths as if we are yawning or sneezing. We are taught to cover our mouths when it's open. |
How does compression clothing work? | My arms/hands and legs frequently fall asleep while I'm sleeping. Any negative effects of wearing compression clothing to bed? |
what are the ramifications of Scotland's 2014 independence referendum and why do most Scots not want independence at this time? | It would cost both countries several billions to create duplicates of all the services needed. The UK's nuclear sub base is in Scotland so that would need to be moved. |
What's the difference between beer, lager, ale, and stout? | This doesn't give you all of what you're asking for, but I found this chart to be useful: _URL_2_", 'You can get a detailed explanation from /r/homebrewing if you want to go deeper than ELI5. Most of these responses have problems. There are two beer types, based on the type of yeast used to ferment: Lager - Thrive in cooler temperatures and are responsible for beer styles such as Lagers, Pilsner .

The concept behind "Injury Prone." Is it just a label or does it hold some scientific backing? | There's many factors involved but yes you can absolutely be predisposed to injury although accurately measuring such a thing is difficult. For one a part of it is genetics. Some people will just naturally be built stronger and put together better as a result which will of course mean less injury. Being taller or shorter or heavier or lighter may or may not be good things depending on the situation. Then there's things like whether you're male or female and your psychological state. The exact nature of the activities you are doing. Things like how hard you push yourself and how mindful you are of not getting injured when you are doing something athletic. For example, do you properly stretch before athletic activity or do you make sure to land correctly on your feet after jumping and so forth an so forth. It would become nauseating to really keep track of it all but if you could and did you would find that some people are gonna be more likely to get hurt than others. |
How can YouTube videos be a "job" ? | I'm not sure about how this works in France, but this is pretty standard advice everywhere: You're self employed, as others have said. You should create a business and operate the YouTube stuff through it. This separates your personal and professional finances, which is beneficial for many reasons. Disclaimer: I'm not self employed, so I can't really speak about the details. |
Why do Christians get so irate about evolution? | It doesn't upset *all* Christians. However some believe that humans were created as we are now some 5000 years ago and that's final. To say that humans came about by some long, chaotic and generally un-mediated process is against what they believe. It becomes a touchy subject because those who argue it most strongly make a lot of noise.As a former New-world creationist, because they see it as a contradiction of their literalist translation of the creation story in Genesis. |
Why are humans so into kissing if it serves no reproductive purpose? | When you kiss another person you're smelling their DNA. This tells you if you should be further attracted to that person or not by judging the compatibility of your immune systems. If you have immunity to things that they do not, and vice versa, then your bodies will be more likely to produce a baby than if you were not compatible. There's a name for it, but I forget at the moment. |
the basic rules of League of Legends so I can enjoy watching a match as a non-player | 5 people on one side and 5 people on the other side. There are 3 paths that lead to their main base. They have to destroy their enemies' 'towers' along each path until they reach the end of one side. Each player tries to stop the other them by fighting them. Once they reach the end and destroy the last big tower thingy on their opponents' side they win. That is the skeleton. |
Why can't people just get divorced? Can they just both agree to go their separate ways without lawyers and such? | It can and does happen but more often than not as with everything things that go well don't make good news or story's and not all marriages end on good terms. |
How does exposure to sunlight generate vitamin D? Some kind of mammal photosynthesis? | Vitamin D3, or cholecalciferol, is a steroid hormone which has a cholesterol precursor like the other hormones in the family. A small 1% of the sun's light energy spectrum is responsible for converting subdermal 7-Dehydrocholesterol into a previtamin D, which then thermally isomerizes to the vitamin form. Great presentation on the topic below, and the reason I lay out during solar noon for about a half an hour when I get a chance, starting late March through the end of September in San Francisco. No sunscreen. The sun has to be at least at 45 degrees or higher at sea level to be able to produce Vitamin D, otherwise most of the UV is absorbed by the atmosphere. So if your shadow is longer than your height, don't bother. Great presentation on the topic._URL_1_", '_URL_2_ Light catalyzes the transformation of this into what we call Vitamin D3. Your body probably makes this from cholesterol and then lets light do its work', "Ten to 15 minutes of sunshine three times weekly is enough to produce the body's requirement of vitamin D. The sun needs to shine on the skin of your face, arms, back, or legs . Because exposure to sunlight is a risk for skin cancer, you should use sunscreen after a few minutes in the sun. - National Institute of Health Another way to get your Vitamin D on, is to measure the time it takes for you to get pink/start to burn, and cut it in half. Get that much per day and you're good to go. |
Why does "rapid rehydration kill"? | All these people just overlooked the nuclear bomb part for some reason everything's irradiated. The person's irradiated. The water, the air. If they were close enough to a bomb to have the water stucked out of them that bad, they were close enough to get hit with a lethal amount of radiation at the least. They were full of radiation, burnt inside and out and on the brink of death; the water was probably their last wish at the time. The person who wrote that they died from rehydration is pulling at strings imo. E: Found what I think your taking about. A woman gave water to a badly burned boy and he passed away after drinking. He didn't die from drinking water, he died from a nuclear bomb. |
