Why do we round up on 5?
Technically you only round up on 5's half the time. IIRC if the integer is odd you round up and if it is even you round down, I could have that backwards.
Why are grenade launchers not commonly used instead of bombs?
Grenade launchers aren't exactly easy to use or get. Why would you go through the hoops and illegally obtaining a grenade launcher with ammunition and hoping that you can hit someone with it when you can just make a homebrew pipe bomb out of relatively simple ingredients and drop it discreetly somewhere?
Why is hitting a wall at 100mph worse than a head on crash with two cars at 50mph each?
Broadly speaking it's because when you hit a wall, pretty much all the energy goes into deforming your car. The wall does not significantly change. But when two cars collide, the energy is split roughly evenly between the two cars. They both crumple and bounce and stuff like that. The result is that when two cars hit head on at 50 mph, they both end up pretty much the same as if they had each hit a solid wall at 50 mph. [They tested your exact numbers on mythbusters once].If the cars are identical, both cars will end up standing still. In this case, the head-on collision is like hitting a brick wall at 50mph. And hitting a brick wall at 50mph is much ~~worse~~ less bad than hitting a brick wall at 100mph
Why are kinder eggs banned in America, but knockoffs aren't?
They're not, technically. Ethnic Stores are exempt from certain laws involving food - including the one about toys inside of candy.
Why do scientists assume an alien species would use the same math system as us.
Every civilization or alien species would have there own code of doing things math wise. However the outcome would be the same and the process similar. You can't mess with the laws of the universe. Everyone just has there own system of coming to the same answer.
Can someone explain to me how from thin air (a wireless connection) I can download little bits of data that fill my computer.
It uses light, just not the kind your eyes can see Just as you can send information to someone's eyes with visible light, you can do it with radio waves. The encoding is really weird, but same idea. Edit to add: Light has different absorption properties in various materials depending on its wave, which is why radio signals can go through walls, while visible light can't.
How is Half-Life constant if radioactive decay is both random and spontaneous?
Radioactive decay is random in that you can't say whether a coin flip will yield a head or a tail. Half-life is constant in that you can say you are 95% confident that if you flipped 20000 coins, you will get heads anywhere from 9850-10150 times, this range gets smaller by the proportion 1/sqrt. When measuring half-life, you don't have 20000 objects, you have sample sizes in the 10000000000000000000's because of how many atoms. That's why you can be so sure about half-life, because you're measuring the property of a system, not of one thing in the system.Imagine tossing a fair coin millions of time. Each toss is random but there is still a distinct pattern.
What an acid trip feels like.
After the first time I took it, when people would ask what it felt like, I would say that it is indescribable. You cannot imagine what it feels like. I've taken it a few times since and still can't think of a good way to describe the *feeling* but I recently watched [Jill Bolte Taylor's] TED Talk and what she experiences when the left half of her brain shuts off sounds a lot like an acid trip . You just experience the energy of the world in a different way.
Why are giants often portrayed as moving ve...ry... sl....ow....ly?
The answer is the square-cube law. If an object or animal is twice as large it will be four times stronger but eight times heavier. This means it can only accelerate half as fast. It may be able to go faster in a straight line but it won't be able to make the same quick changes in direction that a smaller animal would be capable of.
If flouride is classified as a neurotoxin, why is it used in my toothpaste and in the water I drink?
Well its pretty good at preventing tooth decay. Look, do you think that the US government would just pointlessly kill most of its population by poisoning them with fluoride? Fluorine and Fluoride are dangerous, but only in certain concentrations. The amounts in dental work are no where near the level required to cause harm, though they do ask that you don't swallow or eat the stuff.
Why do women look different than men?
Your question is missing the mark. Why would you assume two different thing should look exactly the same? An SUV and a sports car are used for different purposes even though they are both vehicles. Simplifying things won't mean anything if you're dead because you weren't optimized for your role. I'm assuming you are already familiar with the advantages of sexual reproduction regarding genetic diversity.Yes it would be simplified. But a couple of billion years ago, life discovered that mingling DNA worked better. There are organisms that reproduce assexually but they are very simple organisms and anything more complicated tends to use sex. Swapping DNA gives far more possible combinations and therefore more chances for evolution to make something change.
Why are companies allowed to put misleading super-delicious-looking renders of their food on packaging and menus? Why aren't they required to put a realistic pic?
The renders of the food they advertise are meant to convey what to expect content wise, not actually deliver a perfect product. If you've ever watched the McDonald's video on this, they say the entire process is done so that you can see everything that is on the burger at once.
What is the difference between Anime and Cartoons?
While the answers I've seen here are 'good' it gets kind of interesting. The most recent 'dividing line' I saw was this: *Anime: Animated series, produced and aired in Japan, intended for a Japanese audience.* The reason for the specific definition is a [music video] that has caused a bit of a [kerfuffle].
I've heard Canada's prime minister has started the process of legalizing Marijuana. Realistically, how long would a process like that take?
Well, as a Canadian, I can tell you that since the liberal party came into office, no one has been arrested, or cited on any marijuana-related charges that aren't attributed to mass grow operations. It actually hasn't been like that for years. It's a normal thing to be walking down the street and pass someone smoking a joint. The police are not going to arrest anyone for possession, it is a waste of tax dollars hereon out, seeing as how those offenses would likely be expunged like they were in Co. For the past ten or so years, the police forces have supported and protected those smoking mass amounts of marijuana at rallies and protests on 4/20. It just doesn't happen anymore, it's as good as legal here. Just don't be a dealer or grower and nothing will happen.
Why do cable companies not allow the option of picking and choosing channels?
The ONLY way I would ever consider cable would be if they would offer channel picking. Until then, I just watch my freebie channels. I think I get 6 channels that come in pretty good. And for DVDs . there's the library or borrowing from friends.
Why when on an airplane do they ask parents to put the mask on themselves before their children?
Once you get oxygen, you can help your child. If you don't get oxygen, you probably won't be able to help your child. Depending on altitude, you could pass out within 15-20 seconds.
Why is the paparazzi acceptable? Aren't they just stalkers?
It's not acceptable. It's just not illegal. The reason it's not illegal is that there's not an easy way to create a formal legal definition that distinguishes paparazzi from legitimate forms of journalism. And this is why, in general, it's not illegal to be a complete asshole. It's not acceptable to be a complete asshole, but any law that made it illegal to be an asshole would also end up being used against normal people doing legitimate things.Paparazzi would not and could not exist without a public appetite for their product. The people who were losing their shit when Diana died and cursing the paparazzi were exactly the same demographic who bought every paper that promised a pic of Di kissing Dodi or candid snaps of her crying or some other nonsense produced by paparazziill tell you this much if someone was scurrying around my hedges taking pictures of my wife changing or my kids playing id have no problems what so ever smashing their faces clean off with their cameras.. no problem what so ever ', "If I was a public figure, i'd be in jail by now. The first person that tried to sneak into my house to take hidden photos of me would end up in hospital. I don't understand why people are *obsessed* with celebrities. Perhaps the problem is the paparazzi themselves: they are just responding to demand. The problem is that people read and buy the gossip magazines.I have a question that relates to this - how is it okay for paparazzi to take and publish pictures of celebrities kids? I volunteer with kids and you need parental permission if you want to use a picture of their child e.g. For publicity, but pictures of celebrities kids are published all the time', "Then why the fuck a YouTuber have to get someone permission to film them in public? If they doesn't want to be film why do they have to be blurred out?
A curious Australian here. Why do you American's donate your money to political candidates?
Generally it's because we want that candidate to win, and more money for their campaign allows for more ads, visits, general campaigning Edit, more thoughts : that's not to say that they always use this money for campaigns. We all know some politicians can be corrupt and might pocket this money for their own reasons outside of running for whatever office he or she wants. I would only donate if I felt extremely aligned with my preferred choice", 'Political parties need money for campaigns. If they are not getting money from you they will get it from somebody else, and that person will be the one whose interests they will represent.The way I once heard it explained was of all the things you donate to, isn't what you see to he a better future for your country one of the most worthwhile?
why do massive tattoos have to be done in multiple parts
Because it takes a long time and most people are not willing to sit with you for more than 10 hours at once, when it's much more reasonable to do it separately.
Did we tap into green energy at the earliest possible opportunity? Or did we delay it, and there was actually a possibility to start exploiting it much earlier?
Yes for hydroelectric sources. Dams were great because they controlled flooding and provided electricity. No for other renewable sources. Why weren't other renewable sources developed as heavily as coal, oil, and hydro? A big chunk of the answer is energy storage. When the city needs energy, the coal is sitting there waiting. Or the dam's reservoir is full waiting to be opened. Solar panels and wind turbines still have the same problem today, battery storage is expensive and inefficient compared to coal.
Why do I sometimes get that it feels like its itching INSIDE my hand, foot etc..
It's possibly related to complex motor tics. These are issues when your brain needs or feels a want for a certain or strange stimulation. Try to ignore it and when you can't, just do what you can to stimulate it, like stretching lightly.
Why do people prefer Linux?
People have already commented on your school's use. Personally, I prefer it because it is free, open source, immensely customizable, faster, more user-friendly & pretty , and most of what I need to do is available via Linux. For example, I don't use Word; I use Google Drive. Thanks to SteamOS, most of my games are available on Linux. The few things that aren't compatible just aren't compelling enough to stay with Windows.
Is it really possible for a person or entity to get precise information, such as your street location, from your IP address?
Simply put, your understanding is mostly correct. Accurate IP address to physical location is only known by your ISP. Publicly available information can only come from what they provide to other entities. Some services sell geolocation information . Accuracy of such services depends on your ISP giving them your address and IP address. IP addresses are allocated in something called a block. A block can be something like 192.168.0.1 through 192.168.0.255. Blocks of IP address are owned by various entities, your ISP being one of them. Ownership is publicly known and maintained by [IANA]. IP address allocation is allocated by country. If your address comes from a certain IP block they can effectively figure out your country . Beyond that there is no other definitive information they can get about you without hacking your ISP, or your ISP telling everyone. Most ISPs don't give precise physical locations simply because it's a PITA to keep updating that since most ISPs do not give you a fixed IP address. A fixed IP address is usually a service you have to buy.
Why are Americans so obsessed with terrorists?
The obsession drives the populace. Fear drives the obsession. Propaganda drives the fear. Money drives the propaganda. Billion dollars of business provide the money. Politicians are the business' tool who use propaganda, legislation and demagoguery to drive the populace's obsession. This is a self-feeding cycle.
How does sleep paralysis occur and what does it feel like?
It is very frightening, basically your brain wakes up but your body won't move no matter how hard you try, you desperately want someone to wake you up but you can't speak, you can't even control your breathing rate though sometimes I have managed to let out a small whimper whilst trying to scream for help. In plain terms, when you go into deep sleep, your brain secretes a paralysing hormone to prevent you from acting out your dreams. Sometimes your brain carries on producing the hormone after you have woken up.Sleep paralysis occur when your body falls asleep while your brain is still awake. Your brains paralysis your body to prevent you from hurting youself while dreaming.It feels like being paralysed. You can`t move your bodyand in my case, the more I move the harder it is. The main problem is fear.Along with it audio and visual hallucinations may occur. Like shadows coming alive or whispers, talk, strange sounds. You could say that sleep paralysis is physical occurrence, while side effect are psychological.
Why is it preferable to have a handmade car (e.g. Rolls Royce) than one made by robots, when robots are more precise than human hands?
You can get much more customization with a handbuilt car than an automated car. Rolls Royce prides themselves on creating cars that match what the buyer wants. They can put custom star constellations in the roof. They can find the exact materials you want for your seat. They can do custom stitching. Automation works best when you have limited variations, because each variation requires the automation to be designed to handle it. So it works great and can deliver extremely tight tolerances over and over again, but you can't go outside the designed variations.
My wife and I have type O blood, my kid has A. How is this possible?
We were mis-tested at some point when kidlet was a baby too, I think. I'm O, ex is B and baby came back A. I suspect the paperwork got messed up or the Dr read it wrong. Luckily, he looks like dad, so there wasn't any Maury issues, but we did have a good laugh over it.
How to start eating healthier and exercising.
Avoid sugar, processed foods etc. Stick to half a meal being vegetables, quarter carbs, quarter meat. Watch portion size. Main thing really is to try to avoid as much sugar as possible, which includes anything like high fructose corn syrup. I know people say to eat plenty of fruit, but the focus on a diet should be more on veges because the fructose/fruit sugars in fruit bypass the mechanism in the brain which tells you you're full, thus making is easy to overeat. Also keep in mind it takes 10 mins minimum for your brain to register that you're full. Avoid 'diet' and sugar free drinks and food because a lot of the time they still have the same effect on blood insulin as sugar, plus they're generally just more crap for your body to deal with. Read the book 'Sweet Poison', it's really informative about stuff like this. Also, Dr Libby Weaver's books are also really good, there's a lot more biochem explanations in it though Exercise I can't help with, I'm still stuck on it myself. Edit: Just realised what a misleading yet relevant username I have
Sometimes, when I start to sneeze, I don't get to finish the sneeze and it's very frustrating - Why does my sneeze not complete sometimes?
I asked a question similar to this before. You sneeze when their is an irritant present, so your body sometimes will start to sneeze, but the irritant has gone away before you get to sneeze so you don't need to anymore.
Why Tesla's new power wall a big deal.
It isn't. What they don't tell you is the $4,000+ install fee and using it can end up costing as much as $0.30kwh which is as much as three times as just purchasing power. The facts about converting US to non-fossil fuels maybe true but their battery isn't the answer. Source: _URL_2_
What is the big reason that we NEED a manned Mars mission?
Exploration and science in the space age isn't done to obtain some kind of technology or resource that we didn't have before. We do it because we as a species are naturally curious, and we know from experience that expanding and exploring the universe often results in innovations here at home which we could not have foreseen. This isn't Civ 5, so we don't know exactly what we will gain from developing the ability to send a man to Mars, but it is the next natural step for our species and the last time we did this we made great leaps forward in our knowledge and technological capabilities. All of that trickles down into society over time.
What am I feeling in my genital/bladder area when I go down a rollercoaster?
I always thought it was just the rush if adrenaline mixed with the velocity at wich you're falling that made that weirdly nice feeling ", 'those are the g forces making sweet sweet love to your bits. Cherish it, guy', "I'm assuming you're a guy. Cremaster muscle in your scrotum contracts when you're scared, causing that god awful weird feeling in your lower half. Also happens when you, for example, jump off a cliff when playing a video game.I also get the same feeling when I see blood, or an injury ect. So what the hell does that mean?
How did the employer-based healthcare system in the United States originate and why did it develop differently in almost all other developed nations?
/u/localgyro basically has it. But the key point is that there was a wage freeze in the US. Employers couldn't offer more money so they started offering perks, and so employer sponsored healthcare began and exploded. Our allies didn't have a wage freeze and so healthcare didn't become linked with employment there.
Why do so many frozen yogurt shops go out of business, only to be replaced by another one almost immediately?
A lot of trends draw a lot of me-to business owners, who may not have the skill or business savvy of others and fight an uphill battle to compete with the established players. If cash flow is tight, something that is highly seasonal can tough to keep afloat when business drops -- like, say a yogurt shop in the winter. But then somebody else comes along and see a turn-key business ready to open and they fall into the same trap, thinking they are somehow smarter than the last guy. Maybe some are, but many are not or maybe it's something like a bad location and/or too high rent. Nobody is going to be able to cash out in a short span -- restaurants and the like are lucky to break even in years 3 or 4. So it's then going out and somebody else thinking they can do better.
Finnish education system compared to the rest of the world. And why it´s more successful than others.
This is an article on it. _URL_0_ The main points are: formal education doesn't start until age 7, most walk or cycle to and from school, hours are less, homework is light, mandatory 15 minute outdoor break every hour, progress is assessed every day through direct observation, teachers let children be children, classrooms are warm, safe, respectful and supportive, teachers are respected professionals, teachers make the decisions about education, not bureaucrats.
How did people like Adam and Eve, and Noah and his family procreate in the bible? Wouldn't their children be deformed due to the close genetics?
I believe one of the apologists' answers is that they were much closer to the fall and so not yet so impure that they would have genetic problems. Either that or that God prevented them from happening.
Why do grocery stores use huge rows of open refrigerators without doors, while some refrigeration units at the very same grocery store will have doors which would presumably be much more energy efficient?
Everything everyone said about them being surprisingly efficient is true. They can actually be more efficient then ones with doors. Depending on how often or how long they'll be opened. On a meat case where there's always someone looking through the steaks to find the right one the doors would always be open. Or very heavily shopped sections the doors would always be open. The milk and eggs are often in fidges with doors because there's a whole walking fridge behind the display where the back up is kept, and the restocking is done.
Why is it easier to see objects in the dark if you indirectly look at them instead of directly at them?
Your eye has two types of receptors, rods and cones. Cones are good at perceiving color, but not as good in low light. Rods are good in low light, but not as good at seeing color. The center of your vision has a concentration of cones to maximize day vision, which is typically more helpful. But it means at night sometimes you periferal vision can pick up things your center of view can't. Edit: cones= color, rods = low light
if a property bubble bursts and property prices go lower, why is that not a good thing for people wanting to buy property?
Prices may be lower and that's great for buyers, but what can you buy if no one wants to sell and are instead all waiting for the prices to creep back up? Buyers want to buy but sellers won't sell, leaving a period of low activity in the market until the prices come back closer to equality.
Seeing through a mantis shrimps eyes.
Color exists in the mind. Your brain creates the impression of color based on different signals sent to the brain. The mantis brain receives a wider variety of signals, and so can likely discern a greater variety of 'colors.' So where you might see one yellow, the mantis might see, I dunno, four different colors, none of which necessarily correspond to any color you see. That being said, there's not a particularly easy way to imagine colors you can't see, and there's no guarantee 'what' it would actually look like because a system for a human to receive information from 16 different cones doesn't exist.
How does the Monty Hall statistics problem work ?
The easiest way I've found to think of it is to take it to extremes: let's pretend that you're picking one door out of 100. So you pick door 1, and Monty opens doors 3-100, all of which had goats in them. Then he offers you: do you take door 1, or switch to door 2? Your odds never changed; you picked a 1/100 chance and you still have a 1/100 chance. Where are those other 99/100 chances of being right? They're behind door number 2, because every other door has a probability of 0. It's the same with the original problem, but far less extreme. Since the door that's opened is *always* one of the wrong doors, the extra door is always going to be more likely than the one you picked.
What makes someone allergic to a certain thing?
Okay, but have I gained new allergies over the years? Starting when I was 12, I was suddenly allergic to cats -never was before. Then I became allergic to grass, then shellfish, then apples and peaches. It's really obnoxious. I used to eat all of those things growing up but now I can't, and it's extremely frustrating .
how do taxes work for people whose source of income is coming in from many different countries, such as musicians
I imagine it depends on what country you're in. In Canada, you have to declare international income, as well as international tax paid, and generally get a credit for any tax paid internationally, so that you're not being double taxed on the same money.
As an American with a tenuous grasp of the rules of cricket, what would sandpapering a ball do, and why did those Australian players get into so much trouble?
Basically the same thing sand-paparing a baseball does which is why scuffing a baseball is against the rules, too. This is why any pitched ball that hits the dirt is replaced. Pitchers started getting sly and would throw the ball into the dirt a few times to scuff it up until the umpires got wise to what was going on. As an American, I trust you're familiar with baseball?
Why did it take 3 years to convict James Holmes of a mass murder that he clearly commited?
I like the top comment, just adding one part of this case that they didn't include. Holmes tried to get a plea deal. He was going to plead guilty, in return, he wanted a life sentence.The prosecutor wasn't having that shit and wanted the death penalty. Holmes defense was going to be insanity, or temporary insanity. If Holmes would've won, then he could be out walking the streets in a few years after he became 'sane'.
How do smelling salts wake you up after you’ve been unconscious?
Realizing ammonia gasses. I'm a lifeguard and have broken a packet just to see what it was like. I couldn't get my nose within two feet of the packet before my nose began burning like hell. Had a good laugh in the guard house with that.
Why does America hate Communism so much?
I'm guessing because communism is an idea that can just work in theory, because as we all know, people are greedy and selfish.
Why do so many world mythologies associate the sky with heaven?
As a human, you're on the ground. If you want to, you can get deeper into the ground. So far, we haven't found a paradise full of happy souls under the dirt, so it can't be there. As humans, we can't fly, and until very recently there was no way for us to get higher in the sky than the nearest tall object. Anything could be up there, including paradise. Also you tend to make stories about things you can't change. People can move the earth around, swim in water, redirect rivers, all that stuff. Early humans couldn't do anything to change the sky, so it seemed magical and divine.
What does it mean in movies when someone asks "do you validate parking?"
some places have a paid parking structure, and there are different potential prices for the parking there, so if you eat at a restaurant or something that helps pay for the structure they're basically subsidizing the cost of your parking, and they'll give you a piece of paper with a barcode or something to 'validate' your parking so you don't have to pay as much
Why aren't cars getting cheaper and cheaper like computers
With computers, more of the cost of the product is in the development and technology behind it. With cars, it's the same, along with the heavy cost of the materials involved.Because the raw materials still cost a lot, and there are a lot of regulations on car manufacturing. 2000 pounds of materials and hundreds of tests to go through.There's a lot of factors here: 1) Safety - current generation of cars is - on average - a lot safer than what you'd get 10 or 20 years ago at similar price 2) Environment concerns - that drives up cost of cars a lot 3) Taxation - at least in Europe it's significant chunk of automobile purchase you can't skip 4) Features and comfort. Currently I've got two cars that cost around the same when new. One is Honda Civic from 1997 - with two air bags, power steering and electric front windows . There's even arm rest but sadly no cupholders. The other one is Toyota Auris Hybrid from 2014 - with GPS, skyview window, leather seats, air conditioning , automatic parking, rear camera and God knows what else It doesn't have adaptive cruise control sadly ;, parts inventory, etc. And then the cars would sit on dealer lots and not get sold because most people don't want that. Car prices are getting cheaper. $13,000 will get you a much nicer car than it would 10 years ago. A $13,000 car from 10 years ago might retail for $10,000 if it was built brand new today, but not enough people would want it for it to be profitable for the manufacturer.
John Boner says that 40 ultra right members of congress are controlling it. How is this even possible?
Lets say there is the screaming toddler in the grocery store who wants to leave. He will continue screaming and throwing a tantrum until his mother takes him home, and will not stop for any other reason. He can't be compromised with or bought by promises of toys or candy, no matter how sweet of a deal for him. Everyone else in the store can't get anything done because this child is screaming bloody murder, and the child's mother can't get anything done either, because he refuses to cooperate even though it is in everyone's best interest. In the end the only option is to leave the store with no groceries . This seems like a worst case scenario to all of the other shoppers and the boy's mother, however this was EXACTLY what the boy wanted in the first place, and the prospect of leaving with no groceries isn't able to scare him into being quiet, but rather he keeps yelling louder so that this is the only possible scenario. Meanwhile, all of the other shoppers begin to dislike the boy, and by extension his mother, because he was causing such a scene, and if given the choice, they would probably vote to keep them out of the store in the future.
When babies get their first teeth, how do they not constantly bite into their gums?
My 6 month old who had just got his two front teeth started to have a bit of redish discharge from his nose and was getting a bit grumpy. I thought it might have just been some fruit coloured saliva, as he had been sucking on a plum or similar, until he sneezed blood out. I then began to panic and got ready to take him to the hospital. As a last measure i looked inside his mouth and noticed a cut on his upper gum and figured out he had just bit himself. Decided not to take hin to hospital as i could account for the blood. He was fine, and hasn't bitten himself again yet ", 'Baby teeth typically grow in at a certain order.. First the bottom two-front, then the top two-front. This site has a great visual:_URL_1_
Why are some people so eager for the Baby Boomer generation to die off?
Die off is a bit harsh, but a lot of the Baby Boomer generation slow down progress. I work in the tech industry and I feel that 50-60% of my job is to convince clients and co-workers to believe in and use updated technology and methods to solve problems. Part of the issue is they're in very high-clout and powerful positions in many industries and organizations, but their skill set is very outdated and they won't listen to the younger generation who know how to implement solutions that scale and are inexpensive. TL;DR A lot of them are in very powerful positions across many industries but their skill set is very outdated. Their arrogance stops them from learning and improving.
Why are we forced to use banks to receive our income?
The world is moving to an electronic cash world. Employees and employers both prefer direct deposit, it's cheaper and easier to manage. Distributing pay checks takes time. I work for a small business that has 50 employees, at 3 locations. On pay day, someone has to go to each location and distribute checks to everyone, that takes them almost the entire day. Imagine a factory with 1000 employees, at the end of every shift 333 employees will be lining up for pay checks. If the payroll people spend 30 seconds per employee, that's still 2.5 hours spent on distributing pay checks every shift. If you distribute cash, it's even worse. Ask older vets about payroll day at a military base. Multiple armored cars loaded with a few million in cash need a military police escorts. Heavily armed guards managing lines of soldiers trying to get their pay. Armored cars carrying pay roll used to get robbed all the time, checks and direct deposit eliminate all the costs and security issues surrounding having large amounts of cash on site.
Why do competing bodybuilders get such obvious spray tans?
Very little in bodybuilding is actually about looking good. People who say bodybuilders are grotesque rather than attractive are right, but they're missing the point. Bodybuilding is specifically about showing muscle bulk and definition. It's actually not a spray tan, either--it's some kind of gunk that they [apply with a roller].
How realistic are modern shooter games?
Here's a very representative example: if you shoulder your weapon in CoD/BF/Arma and it has an RCO it doesn't move significantly if at all It moves a fucking lot in real life.My favorite arguments against people who think games like Modern Warfare and Call of Duty are training kids to be killers: no one ever got PTSD from playing war video games.
How does zeroing work on a sniper rifle scope?
You change the angle between scope and barrel. Since gravity affects the bullet, it will drop during it's flight. To counteract this, the bullet is shot slightly upwards, and the flight path is therefore an arc. The further you want to shoot, the larger the firing angle.
How a VPN increases anonymity?
All of your data goes encrypted to your VPN's server. So basically your VPN re-directs your requests to the website.The website only see the VPN's IP adress and doesn't have any information about you.

Why don't we point Hubbles and/or all other "magical" telescopes to our closest celestial body and show everyone once and for all, the artifacts of human Lunar landing?
Even if Hubble could do that - and it can't - it wouldn't be worth the time. A space telescope has a lot of demands on its time and catering to the insane theories of a pack of fucking idiots is not a useful use of that time.
Do Asian people write code in Asian characters?
For a long time, asian programmers wrote pretty much all their code in western programming languages, generally based on english. That doesn't necessarily mean they actually learned english, though. You can understand what keywords mean in the program logic sense without understanding their linguistic roots. In recent times, I believe a few programming languages have appeared that are actually based on asian languages and are written in asian characters. See [here] for a list of the more prominent of these.To be frank, programming languages are languages themselves. The only thing in common with English is the use of the 26 letters of the alphabet. However that doesn't make them "English"Well I would think "learning a programming language" and "learning English" are different: I mean, just look at the thirty year history of Japanese video-games. I'm assuming they were all programmed with languages resembling English, but when it came time to write dialogue they were barely understandable, until they started hiring professional translators._URL_3_ They do exist, but they're not as popular as you might expect.
How it wasn't immediately obvious that smoking was detrimental to your health
I'm a long time smoker and I can say that it actually takes a long time for you to realize the impacts that cigarettes have on your health. I was smoking daily in my late teens, and I was still weight training and running seven minute miles. It takes a surprisingly long time for your habit to pick up more heavily, and for you to have noticeable wheezing, shortness of breath, dry mouth, etc. By the time I realized I had a problem with nicotine, I had a problem with putting it down despite the notable health problems. *EDIT* Additionally , tobacco was historically a cash crop. In some ways it still is today for certain regions. There is and has been a massive social influence based on tobacco use that equates to things like adulthood or manhood specifically. So not including the obvious physiological impacts, the sociological impacts play a large part. Also in terms of the history of tobacco, people probably didn't smoke as often daily because of the socioeconomics of the time, while also having to do more cardiovascular exercise given the lack of modern technology.
What is left to discover about comets and what are some potential surprises that could occur once we start analyzing the comet we are landing on?
Simple. Imagine trying to deduce the properties that make marble such a desirable material to craft statues from if the only specimen you have to work with is a raw diamond? Comets come in different 'flavors' as a result of the specifics of their origin, some might be mostly ice-balls, others might be rocky ice-balls with different minerals being represented in different comets. Obviously, the more specimens you have to work with, the better you can understand the nature and scope of the system you are working with. Comets appear to be the result of processes related to the creation of something as large as our solar system, with large variation possible depending on the local conditions found at the time each particular comet was formed.This should give us plenty of information if we ever have to send Bruce Willis up there again.Lots of good answers in here, but I just want to point out the biggest potential discovery: We don't know, we haven't discovered it yet, which is why it is so important to simply explore. :D", 'ELI5: How do they plan on staying on comet? Does it have gravity? What would be holding it on?They smell like rotten eggs, that was a massive discovery', "Carl Sagan's Pale Blue Dot gives a great argument as to why comet landing and exploration is so important. The practice and techniques to successfully pull this off matches the potential of knowledge we'll get from the comet itself.
Flooding An Engine? What happens, how does it happen?
A blinking check engine is indicating immediate damage to the catalytic converter from a far to rich or far to lean air to fuel ratio Edit: flooding, if referring to water in the engine, combustion chambers, will cause a misfire if only a little water but if it's too much water it will hydrolock the engine and you would here a loud noise then the engine would stop and probably be fucked. Flooding with gas in the chambers would cause a very rich mixture witch would then flash the check engine light.
Why don't we like some foods that are beneficial to our health, shouldn't our bodies reward us?
Too long; won't read: Certain foods helped our brain evolve into the complex things they are now. So they benefitted us as we evolved, but now we can access these things very easily and therefore abuse them because our brains are wired that way. Evolutionarily, the first ancestral member of the genus “homo”—Australopithecus—ate mostly fruits and vegetables and consequently, had a much smaller brain. Our complex brains today require a great many calories and a lot of energy to function. Australopithecus had a brain 35% the size of ours. About the time Australopithecus went extinct 2 million years ago, Homo Habilis came around. Its brain was 50% bigger than Australopithecus, its teeth were sharper and smaller, and it had a more efficient digestive system. This was also about the time that Homo Habilis began to control fire. All of these clues indicate that Homo Habilis ate meat. Part of why our brains have been getting larger evolutionarily is because of this higher-calorie diet. Looking at our brains today, eating foods high in fats not only activates the pleasure centers of the brain, but it also activates the touch centers of our brain, new research shows. We get the same feeling from junk food consumption, this research suggests, as getting a hug. It really is “comfort food.” Eating unhealthy foods also releases serotonin, which helps us feel more relaxed and/or euphoric. This is why many people will eat unhealthy foods as opposed to nutritionally rich ones when they are stressed or depressed.

why hasn't the USA declared war since WW2?
You'e asking what it would take, it doesn't take much - in the case of Haiti all it took was for the Haitian population to democratically elect a president that had something real to say to the USA and UN.

Why does the the thermostat need someone to direct it to either heat or cool the room? Why isn't just providing the desired temperature enough for the system to figure it out itself?
My Google Nest does. Most thermostats you install yourself will take a range and keep it inside that range. You're probably confused by older thermostats and/or new building thermostats. With new building thermostats it's fairly simple - the builders were cheap and a fancy thermostat costs more.Newer thermostats commonly come with heat, cool, and auto settings for the mode of operation. The auto setting usually incorporates a programmable deadband that is factory set to 5 degrees. when changing the heating setpoint in this mode from 67 to 68, you’ll notice the cooling setpoint raise from 72 to 73. This allows the HVAC system to run without “fighting” itself. It works well, but i’ve seen most customers prefer the swap modes manually.
Why do everybody yawns after someone else yawned ?
It's not even known why we yawn in the first place. This presents the problem of answering why yawning seems to be contagious.
Why do people from rural areas tend to be more conservative and people from urban areas tend to be more liberal?
In a word: Isolation. When you're closed off, you can afford to shut down or ignore other sources of information and other ideas at variance with your assumptions. This isolation also helps to foster narratives of self-sufficiency and personal toughness that make it easier to imagine that people outside of your sphere seem to lack these qualities. Anyone from somewhere else, who looks differently, speaks differently, lives differently, or has different habits can be very easily and succinctly otherized, since those presumptions and biases aren't challenged but rather supported through the isolation that makes them possible.
What happens if you point a laser or flashlight at an overhead flying plane?
Normally nothing as the cockpit is on top, but if you're near an airport you can temporarily blind the pilot as they're landing Generally still not a good idea no matter how high up the plane is
What exactly is 'First past the post' voting?
It is a system where the person with the highest amount of votes wins. It has its flaws, particularly in single seat constituencies. So if one candidate got 40%, the next 35% and a third got 25%, the candidate with 40% would win although the majority of people did not vote for that candidate. If that result was repeated across the country, in theory you could have a party that got 40% of the vote getting 100% of the seats, and leaving 60% of the people with no voice. This is why largest parties in countries that don't have a majority of the support like the idea of FPTP. Proportional representation is better, as combined with multi-seat constituencies, it gives a fairer result in line with how people voted.
What are some basic concepts of musical theory that will make people better appreciate "good music"?
For me it's little to do with theory or complexity, and more about limiting the use of musical tropes whilst earnestly conveying an emotion, a story, or otherwise affecting the listeners emotions. Music, like all art, is by nature derivative. But it is still possible to take well-worn genres, chord progressions and other musical devices and put them in a different context, enhance them or otherwise add value, provided it is done so with sincerity and conviction. Bad music is bad partly because the performers don't 'believe' in what they're doing. They're just going through the motions and not investing themselves emotionally in the process. You can literally hear the apathy coming out of the speakers accompanied by hackneyed performance/production. Of course this is all just a matter of opinion and depends on your musical upbringing and is influenced by your peers and life experiences. Hear the right song at the right time whilst in the right mood and it will stick with you, no matter how trite it is.
Why is a two-state solution for Palestine/Israel so difficult? It seems like a no-brainer.
Palestinian here: Israel and Palestine are so connected in very different levels, these connections make it very hard to simply separate it to two states and move on. Other than that, Palestinian are not mature enough to have their own state with borders , but this is the truth, Israel knows that, and they won't leave the borders of Jordan just like that, Palestinians don't have army, they have a LOT of corruption, and they need a lot of work before being able to become a successful state , leaving the borders will create a lot of trouble to Israel itself as there is no clear borders for the west bank with Israel. Third, which is probably the most important thing, is religion, in Jewish religion, what really matters is Judea and Samaria Area which is the west bank basically, there is no mention to Telaviv, Natanya in the bible, however there is Hebron, Nablus, Jerusalem, so they will not leave it just like that. EDIT: I can think of another reason which is Israeli Allies, Arab are standing next to Israel, as they have a lot of common interest in fighting Iran and Hezbullah.
If I was dehydrated and there was only alcohol to drink, would drinking it make me even more dehydrated?
Don't have a source for it, but I believe there was a Reddit post a while back that showed 10% was the cutoff for dehydration outweighing hydration.Back in the day Alcoholic drinks were actually safer than a lot of water. Dark ages and stuff everyone drank ale.
So how do I get rid of bed bugs?
Put all your linens in large garbage bags and keep them in your car trunk for a few days..they can't live in the heat and without much air. This is how we treat them with our home care patients. However, you really do need some type of professional treatment, those bugs are some nasty mothereffers!", 'do like the hotels do. plastic wrap your mattress, send it to the incinerator. go buy a new mattressI used to do pest control. Bed bugs are hard as shit to get rid of. If its a full on infestation that has been there for months, you have to treat the entire house professionally. In a large bed bug infestation I have seen them hiding behind picture frames on the wall. Call a company and get quotes. Make sure you get a guarantee because it will most likely require more than one treatment[Cyfluthrin and Imidacloprid] and [Chlorfenapyr] the three together. Get a neonicotinoid, a pyrethroid, and a "other". Heat treatment may be your best bet though. I personally am curious what levels of ozone beg bugs can tolerate
Why do you have to download Java and Flash to run things in Java and Flash, but don't have to download C/C++ libraries to run programs that are coded in C/C++?
You need plenty of c/c++ libraries to run programs. Most of the time if an application is not standalone, the developer builds an installer that will place these libraries somewhere, then register them for you. Otherwise you'd just start the executable directly, every time. Bad answers everywhere.
Why is it so hard in the US to execute people fast and painless?
We want to have execution seem simple and painless; a person simply falls asleep and then dies. But it's not so easy to do this predictably. The classic method for lethal injection involves a fast-acting sedative, to make the prisoner unconscious. A second drug is given which paralyzes the body, preventing respiration, siezures, or even reactions. The last drug stops the heart. Given to a person who has not been paralyzed, the body's reaction would be gruesome to watch.
How do animals know not to breed with their own siblings?
It's probably the **Westermarck effect**. *The Westermarck effect, or reverse sexual imprinting, is a hypothetical psychological effect through which people who live in close domestic proximity during the first few years of their lives become desensitized to sexual attraction. This phenomenon was first hypothesized by Finnish anthropologist Edvard Westermarck in his book The History of Human Marriage as one explanation for the incest taboo. Observations interpreted as evidence for the Westermarck effect have since been made in many places and cultures, including in the Israeli kibbutz system, and the Chinese Shim-pua marriage customs, as well as in biologically-related families.* [Westermarck effect]", 'Well, some animals actually undergo sex with their own relatives or siblings. Some kind of meerkats and mongoose keep their breeding ground within the family itself, differentiating family or the herd with their distinctive odour. While some animals follow the "unwritten law" about not breeding with their own offspring, some do actually do that. This phenomenon is also called the "Oedipus complex" named after the king Oedipus. Some kind of monkeys have been found to show this behaviour. While, this is the case of animals which are wild and free, in captivity it could be entirely differenti have heard animals can detect compatible DNA with pheromones and such. Including humansHow do you? Our brains are wired to not naturally be attracted to family.
Why do some jobs regularly drug test?
100% liability issues. I have to operate mop the floors at work. We all know that some drugs like marijuana don't have serious side effects, but it is known to alter your state of mind. *don't downvote me /r/trees :(.* But as an insurer, who would I give a better premium to? A company who I know 100% has sober employees, or a company who I have no idea the personal habbits/what they were bringing in with them to work.
Why can you be tired all day long, every day of your life, but as soon as 8pm roles around you're (I'm) awake
It's related to your hormones, but essentially, your body is secreting more adrenaline into your body so you feel more awake since it's late in the day.
Why you wake up when you get close to dying in a dream
You wake up the second you hit the ground and realize it's a dream, Because your body has no idea what it's like to die , so it can't simulate it? I dunno just guessing
Why cities can't rebuild abandoned buildings?
Depends whether it's cost effective/building has current-day use/need, and whether the building is structurally sound. What more often happens is that they tear them down to get rid of buildings that could become used by drug users, gangs, homeless, etc.; attract pests like rats; and remain a safety/fire hazard.
Why can't you just let a cat be stuck in a tree? Would it die up there or would it eventually figure out how to get down?
Friend of ours had a stray cat stuck in a 50'+ pine tree in her yard. Up there for weeks. She figured it had to be coming down for water/food at night, because it had been up there for nearly a month. That is, until a gust of wind blew it out, and she saw that it had dehydrated/starved up there. Poor thing was just a skeleton with skin and fur.
Why is there no measuring unit for darkness?
You can measure the weight of a shadow. Not that it's the same just thought I'd throw that out there.
Why are so many venerable firearms designs out of production?
The truth is there are better modern guns out there. People don't make many muskets for example because people would prefer to purchase the new designs. Collectors may really like the designs but the manufacturers didn't stand still.
Why have there been no supersonic air travel services since the Concorde was decommissioned?
One big factor is that people get unreasonably snippy when you break the sound barrier above their house multiple times a day every day of the year. It's basically just Nimbyism, but airlines don't really have a choice but to give in. That means you can only fly from airports too far from civilisation to be useful.
What happens to a fly when It gets inhaled it and doesn't get coughed back up?
It probably wouldn't get into your lungs, because your reflexes are usually quick enough to block that passage. I don't see how it could end up anywhere than in your stomach, where the digestive juices would make short process of it.Why, oh why, would you swallow a fly?
How does 'Trickle down economics' work and how could this benefit the poor?
Trickle down economics is a flawed theory that works mainly on paper and not in application. It is supposed to encourage the wealthy citizens and business's to spend and reinvest their earnings / tax savings back into the economy which helps the 99%.
Why do some lightbulbs blink several time on and off(and some dont) before finally lighting up?
As others have stated, this is something only fluorescent lamps should do. In order for the current to flow in a CFL, it has to first create a plasma inside the tube. A hot filament is used to emit electrons and knock some outer electrons off of gas atoms, giving them a charge. Then a current can be run through the plasma, and the glow of that plasma arc is what generates the light. After the initial creation of the plasma arc, the applied voltage must be reduced or the bulb will essentially burn itself out. In addition, the creation of the plasma is a bit different each time. These combine to make the startup operation a bit tricky. The circuitry that controls all of this is designed to automatically compensate, but there's always a tradeoff in such circuits between fast response and over-responding. The bulb also changes how this all happens as it ages, so you might see it happen more often with an older bulb.That is a "slow start" series ballast system. What is happening is the lamp starts "cold", in that it cannot initiate or sustain an arc. The starter can, and the heat of it causes the thermal starter element to short, which applies full current to the heaters in the ends of the tube. With starter closed, there is no heat to keep the starter element closed, so it opens. Hopefully the tube heats warm enough to sustain an arc, but if not, it re-tries the start cycle. When it successfully starts, there is no current to go through the starter.
Why did the Pilgrims starve their first Winter in Plymouth when there is abundant fishing & shellfish there?
They didn't starve, they arrived late in the season and had brutal weather to build housing in so they had to stay aboard ship for pretty much the entire winter. Keep in mind that the ship was overladen to begin with due to the loss of the 'Speedwell', I think the she was about a hundred feet, and there were over a hundred passengers. A rough crossing weakened folk, then the poor living conditions aboard exacerbated every illness, toss in some scurvy, and the fact that only fifty or so men were able bodied by then, their time went to building. It was the end of January before they could even off load the provisions into their new buildings, living on the boat over winter in such cramped conditions would have been horrendous, check out the boats of the day. Some didn't get off the boat for over six months. It wasn't the lack of food that got them, it was more an underestimation of the trials ahead, although they came from an agricultural background originally that didn't make them automatically suitable explorers and settlers, but they weren't too bad at it! Not only did the colony survive they made great inroads in developing good relations with the local Indians, and they did it without a local support group like a nearby town. I just looked it up, forty five out of one hundred and two immigrants died. EDIT: This is only about the first winter, as you asked.
How can Americans find the time and money to afford the lifestyle I witnessed in SoCal?
It's true we work longer hours and get fewer vacation days. It isn't true that we're unusually poor. US GDP/capita PPP is higher than every country in Europe except Luxembourg, Norway, and Switzerland. Also La Jolla is literally the priciest neighborhood in the nation. Or at least was in 2008-09 according to wikipedia. _URL_2_ There's a reason Mitt Romney lives there. California is also wealthier in general than, say, Idaho or Missourri. But tourists don't go to those places for the same reason that rich people don't live in those places . There were a lot of people at the beach because there are 1.3 million people in San Diego plus tourists and it only takes a small portion of that number to be at the beach at one time to make it crowded. There are some huge stretches of the California coast that are nice and empty. There's also a 20,000+ university in La Jolla. Those kids aren't working 9-5s.
How do film director's hire children to act in movies that have a lot of gore or other mature content?
The way movies are filmed it may be scary and stressful to watch but acting in it isn't the same experience necessarily. I've heard an anecdote that the kid that played Danny in The Shining had no idea it was a scary movie until he ended up watching it 7 years later as an adult.
Can you "store" light? With a box?
The solid answer no. After getting the light in the box, you'd have to close it before it escapes. Which is not humanly possible, as light moves faster than you can think, let alone react to.
How can 'magic mushrooms' permanently change your personality?
For most of my life, I had a fear of dogs, and some disgust of them . Then I tried LSD . Now usually in life, I think about 'perspective' alot, like how other people see the world is usually different than mine, among other similar train of thoughts. Perspective was the 'theme' of my trip . There was a dog present, and my jacked up brain started thinking that the dog is a problem because I perceive her as one; if I didn't look at her from that perspective, she'll stop being a problem. It was like a switch clicked in my brain. To this day , I'm totally fine with dogs.The short version, for me, is that mushrooms allowed me to look at myself more objectively than I ever had. Because of what I realized, my personality changed permanently for the better.There's a reason it's called tripping. You go on a trip, a journey. A journey can change your perspective on things.
Why was homosexuality more accepted and widely practiced in the ancient days (e.g., Greece, etc.)
In those times, men were the most important people in society. They had more of the rights and priveleges to be had. Men did love women, but the women didn't have the same rights and were considered second-class citizens. Love between two men was thought to be superior because the male gender itself was thought to be superior. The attitude in some cultures was that loving men was was natural, regardless of gender, and pretty much encouraged. There's not much to be read about lesbians in those same times, ever notice that?
Why are salaries at fast food places like McDonald's so low, even though they're multi-billion dollar companies?
The market forces of supply and demand. If there are plenty of workers willing to do a job, wages will stay low. If there is a shortage of workers willing to do a job, employers must raise wages in an effort to attract better employees and to retain them. Doctors get paid a lot, for example, because they have to do all sorts of school and pass exams first. This is a barrier to entry. Not just anyone can be a doctor, which limits the supply of doctors, while they are highly demanded as everyone needs healthcare at some point or another. On the other hand, most people with a pulse and basic communication skills can work at McDonalds. To hire good doctors, employers need to be willing to pay a lot of money. Working at McDonald's isn't a high skilled job. Therefore there are lots of laborers, a huge supply, who can do that job. If someone quits flipping burgers, there are plenty of people looking to replace him or her. When there are more laborers than jobs , wages stay low.
Why is it only possible for the coldest temperature to be -273 C, but the highest temperature can be a decillion degrees C. (Referencing the chart posted in /r/space.
Temperature is a measure of how much energy is in the system. That energy has a lower limit, 0° Kelvin, but not an upper limit. Logically, you can't go any lower than 0 but there is nothing stopping you from going upwards to infinity.
How do people in wheelchairs manage to stay at a average weight while not being able to exercise?
Plenty of people don't exercise, it's all to do with what you eat.They exercise a lot. It is a massive upper-body workout every day for them just to move around and do basic functions like getting out of bed or going to the bathroom. Add to that actual weight training, and playing wheelchair sports and they do not have to put in much more effort than an able bodied personThere are plenty of ways for people in wheelchairs to exercise. _URL_2_ _URL_1_ _URL_0_
Why was Uber's culture a big deal?
Some customers didn't care, some customers did. Like how some people don't want to shop at walmart because of how they run out mom & pop shops. Or how some people won't shop at hobby-lobby because of their lobbying for political views. Would you shop somewhere if you know the CEO was a big donator to the KKK? Or was a massive SJW? Some people vote with their wallets.
Why is insurance on rental cars so expensive?
People have rental cars for short periods of time and then they never have to deal with them again. Therefore people naturally care less about them and treat them worse than their own personal car. Also people sometimes take out rental cars just to cruise round and destroy them. Not that common amongst older people but that's why rental companies have excess charges for younger drivers
How does Powerline networking work?
Others have already explained how they work technically, but I'd like to point out you've got a good risk that you're not going to get your full speed from them. It works fine for something like a TV or music player but if you want to max out your gigabit line you should run a proper cable.
