why is a ceiling fan virtually silent, but not box fans/stand up fans?
It's speed. Box fans are smaller so you want them to go faster. When I turn my ceiling fan on top speed, I hear it.Ceiling fans are bigger, spin slower, and have differently shaped blades. The purpose of a ceiling fan is to quietly circulate air through a room. Box and stand fans spin fast and with blades designed for aggressive airflow. The purpose of a box fan is to deliver a directed flow of air. Being quiet is of secondary concern.
Why is it that some primetime shows have 20 episodes per season, whereas others only have 10 episodes, or two 8-episode "half seasons"?
Because different shows have different scheduling needs and different paces at which they want to put the story out there. It's usually the network's decision.
How does weather forecasting work, and how do meteorologists predict the weather days and weeks in advance with such a high degree of accuracy?
It's called "modeling". Using a network of [weather stations] around the world, meteorologists can analyze wind speed, direction, temperature, barometric pressure, humidity to form an accurate picture of the current state of the weather, and how it's changing over time. From there, it's just a matter of using a computer model to look at the current state, the past state, and predict how it will be advancing in the future. When they're breaking it down by the hour, they're looking at the model and reporting what is expected to happen. If a rain storm is moving at 10mph west, modeled to continue that path, and you're 50 miles away to the west, it's safe to assume that you'll be seeing rain in about 5 hours. There are multiple "models" that compete. Some predict certain weather types with higher accuracy, some work in certain regions with higher accuracy, which is why you'll sometimes see reports showing the predictions of different models . TL;DR: Computer programs called models, using data collected from weather stations placed around the world, refined with years and years of data to be as accurate as possible.Is it highly accurate days in advance? I'm asking seriously. I notice when I check my location's forecast say for Sunday there can be a 70% chance of rain then I check again tomorrow and it is changed to 20%.
Why are there species-specific names for groups of animals? Murder, pack, gaggle, court, etc.
Because Victorian biologists decided there should be. And there's an awful lot of stuff we do that originated in the Victorian era. Edit: And no, more recently discovered species don't have group names like that.
If listening to music at high volumes is bad for your ears, why are headphone / PC amplifiers such a big deal?
Headphone amplifiers are not merely just for increasing the volume. There are different specification for each headphones namely impedance this value means it is harder to drive . If you put a 600 ohm headphone on a soundcard/headphone amplifier that could only power a 300 ohm headphone, the volume that will come out of the headphone can be adequate but the volume knob will be up almost tonits maximum. Thus somewhat distorting the sound to increase volume. The sweet spot for volume to get the full quality of recording is at 50%.It's like asking a small compact car to do 100MPH down the highway versus asking a supercar to do the same. One will be a lot more comfortable and pleasant doing it than the other. Some headphones require more power than others to give acceptable volume levels. The audio quality of a sound source that's being asked to power more than it's designed to is almost invariably very unpleasant. Sure you might be able to turn the volume up to the point where it's loud enough to hear OK, but that might be straining the amplifier to the point where the sound **quality** is starting to degrade. So the way you get around that is to put another amplifier, designed to handle the power, in the middle so it does the heavy lifting of giving you the volume instead of your sound source. Now, none of the kit is being asked to do more than what it likes to do. Result is probably much the same volume as you had before, but much higher quality.
why haven't consoles offered the option for multi-monitor gaming? Hardware limitations?
Less hardware limitations, more interest limitations. Like any device, consoles are going to be developed to meet the needs / wishes of most of the target market. And most of the people playing consoles do not care for multi-monitor gaming. Half of the advantage of a console is that you can easily plug it into your tv and there you go, you are ready to game. Multi-monitor gaming already takes a slightly more complicated set-up, more TVs and so on, and most people just aren't interested in it. And, as with any device you are making, you are going to aim for the least amount of costs when producing, and putting in extra hardware/software that most of your target market won't use will only make your device more expensive without really leading to more sales.
Why do only mediocre bands participate in Eurovision?
Because it's not relevant. It's not a measure of quality. It's not a prize that's respected in the music industry. It's just television entertainment.
Why do cats love small cramped spaces like boxes or under the bed?
They love to watch others while being in a safe place themselves. Sitting in a box is the perfect place to watch people without fearing an ambush yourself. People often mention "cat chess", i.e. several cats that keep repositioning themselves so they can watch the others while being as hidden as possible themselves.It's a matter of safety, comfort and preserving body heat as part of a cat's natural instinct.
How did people translate languages accurately when they didn't understand a word the other person was saying?
If you have a living person who speaks the other language, you can work together to figure out each other's language, especially if you know anything about linguistics. It might take some time, but you can work it out with another person. If there's no living speaker then you need some kind of reference that let's you place words in context. You've probably heard of the Rosetta Stone. Before we discovered the Rosetta Stone we didn't know much about Demotic script or Egyptian Hieroglyphics. The Rosetta Stone is a tablet with the same document written in Greek, Demotic script, and Egyptian Hieroglyphics. We did know Greek, so we were able to figure out the other 2 thanks to that reference. That was a HUUUUUUGE development for linguistics and opened up a ton of understanding. So you don't always have a reference like the RS, but the point is you need some kind of reference. Often just archaeological artifacts. edit: Demotic script, not Sanskrit. Also simplified some of the importance of the RS.
why do our stomachs growl?
The "growling" is due to your stomach muscles contracting in order to mix, crush, and propel digested food. Usually you won't be able to hear the sound because it is masked by the food being digested. However, a few hours after you eat, your digestive tract will contract in order to push any remaining food or bacteria down the digestive tract and say "Hey, I'm ready for more food" . This will repeat every few hours until you eat again.
Race, Breed, Subspecies: what are the differences?
Races only have small physical differences that aren't really reflected in the genetic makeup. It's very possible for there to be more genetic variation between two Germans than between a German and a Kenyan, but the two Germans are still of the same race just because of their skin color. Subspecies have more significant differences that are actually reflected in the genetic makeup, but they're still close enough that they can breed with the larger species as a whole, though typically their offspring aren't as fertile or viable as when they breed within their subspecies. The line between subspecies and species is pretty blurry as there are animals that we consider separate species than can also breed like lions and tigers. Breeds refer to differences that were selected artificially like dog, cats and horse breeds.A species is defined by differing characteristics. In genetics this is easy as the differences in the genes can be compared. With dinosaurs species must be defined by physical characteristics and this can cause errors where juvenile dinosaurs can be mistaken for a separate species. In both cases it can be hard to decide exactly when one species ends and another begins. Classifying early hominids for example, if you find skulls with heavier brow ridges do you call that a new species or is it still the same species that's adapted a little. This is where a sub species can be defined. Breed is used to describe things where they're definitely the same species but characteristics are different. Dogs are all genetically the same, and have similar behaviours but look different so are breeds. Wolves look like dogs but are genetically different and behave differently, they are a species. Different kinds of wolves are sub species. Race is a social construct created by people to create emotional borders between "us" and "them" or to create cultural divisions. All humans are part of the same species and we all behave broadly the same. Look up "othering" for more info, it's largely to do with getting people to like or dislike other people.
When you're about to fall or spill something what is that feeling in your belly?
It does have to do with adrenaline! When you become anxious or afraid, your body's stress hormones move blood from one place to another. Your digestive system needs blood to make it work. But if you're in danger, you don't need your digestive system to work as hard any more. The blood is sent to your brain, your nerves, and your muscles so that you can act faster. The warmth you feel comes from this movement of blood. When you're done dealing with the stressful situation, the blood goes back to where it belongs. Sometimes, people who stay stressed will lose weight because their body forgets to digest food and keeps blood flowing to other places for too long.
How do they come up with the names for medicine?
a lot of the time they are shortened versions of their very long and complex chemical names. for ex, Ibuprofen from **isobutylphenylpropanoic acid** Do you mean the real name of the medicine like aripiprazole?Or the marketing made up name like "abilify"?
Isn't threatening to revealembarrasing videos of people for money extortion? How are people not prosecuted for it?
It is indeed extortion and illegal. Many people end up going to jail for it. For example, [Autumn Jackson] was sent to prison for trying to extort Bill CosbyThe reason that extortion can work is that in order for anyone to be prosecuted for it, the damaging information *has* to become public. Whenever you hear about someone being prosecuted, it's because the victim decided "Fuck it, let the world know, I just want this asshole in jail."
Why do flies come back to me after I try to swat them and miss? Doesn't it register into their fight or flight response?
They can't really comprehend that you're actively targeting them. The most they deal with outside of humans are animal tails swinging in their general direction. Flies don't understand hatred, they are beautiful, shit-eating beings like that.
Why does 'republican' mean something completely different in Europe compared to what it means in the US?
Because it is the name of the other major party of the US, so the political ideology and goals of that party greatly define what republican means in the US. In Europe on the other hand there are still a lot of monarchies so republican is more understood as the opposite of monarchistIn countries that have traditionally had monarchies, republican means someone who wants to abolish the monarchy in favor of a republic. In the US, Democrat and Republican are just brand names that have little to due with their dictionary definitionsand remember, it's capitalized to denote the difference. "republican" still means the same thing in the US, though you may have to explain what you mean when speaking. the party is the Republican party, the system of government is republican.
How can things like plastic be clear(transparent)?
Funny you mention stretching because this actually a way you can make a polymer , which forms a plastic, not transparent. Basically what happens is this: in an unclear plastic the light gets refracted inside the plastic. You can actually still see light come out at the other end, so light still passes through, it just comes out in all kinds of directions giving the property of it being unclear. The reason this is the case because of the alignment of the polymer molecules. When they are neatly crystallized they sort of form an internal mirror system which causes the light to scatter everywhere. Now in a polymer where the molecules are aligned kind of randomly, for example in plastic bottles or bags, this internal mirror system doesn't happen. So light does not get refracted and scattered, but just passes through. This causes the plastic to be clear. When you actually stretch some polymers you can actually see the plastic change from clear to unclear. This happens because when you stretch the plastic you are actually aligning the molecules of the polymer. This causes the internal mirror system I talked about earlier. Hope this helps, I took a lot of shortcuts and didn't explain everything 100% correctly but this is the gist of it.
When I was a kid, why was channel 3 the chosen AUX/input for most game systems or VHS players?
Most devices that used RF adapters actually had switches on them to select between channel 3 or 4. See: _URL_0_ Most media markets did not have something broadcasting on *both* channel 3 and channel 4 because the frequencies that carried those particular channels were more likely to interfere with each other over the air . Channel 1 was off-limits to US broadcasters, but it wasn't an option for AUX devices either because all but the earliest TVs couldn't even tune to it . So, choosing Ch3 for RF adapters was mainly a convenience, although, as you say, even if your area did have something on both 3 and 4, it would not limit your ability to use an AUX device on those channels when you wanted to.
How do single-file games work?
It finds things inside it. .dat is a database file type, it's pretty much just a glorified folder.
Why are chairs slightly incurved instead of the other way around ?
Some busses and trains in sweden actually have chairs that make you sit with a straight back, but i think It's cause people find those types of chairs more comfortable
What is the connection between birds, reptiles, and dinosaurs?
Dinosaurs are a diverse clade of reptiles. Birds are descendants of dinosaurs, and technically by the phylogenetic system thus are dinosaurs and also reptiles. However, by that measure, humans are also reptiles . As such, there are limits to the usefulness of applying such classifications too widelyReptile is a poor term in relation to evolutionary theory. Reptile applies to any animal with a host of features that may or may not be closely related at all. This is especially notable with extinct animals like dimetrodon who are often called reptiles but are really closer to mammals. Dinosaurs, because of their skin, are often called reptiles. But they had as much in common with modern snakes and komodo dragons as we humans do.
why people while hugging in non-romantic situation are "tapping" each others backs with a palm?
It's just a friendly thing to do that stems from mothers burping their babies and then later on patting their kids on the back as a friendly good job or hello. Later on it just continues and people continue to do it. It's an old habit of society.Edit: had a typo and fixed it
Why are chips and salsa generally given for free at most Mexican restaurants?
It's like bread and butter at an Italian restaurant. Something to snack on before your meal gets out, cheap and generally likable.
Why does brightness and staring too much at a screen produce eye fatigue and headaches?
This is what's known as computer vision syndrome. When you're staring at the computer screen for hours at a time, your eyes have to stay focused on it. The muscles that focus and move your eyes are fast-twitch muscles, and aren't really designed to focus the way we do on computer screens. IIRC, when using a monitor, our eyes have to focus and refocus thousands of times an hour. We also tend to blink less, so our eyes dry out As far as the light goes, it's the blue light that gets ya. Blue light penetrates father into the eye than red light. To help reduce this, there are things you can do: 1. Make sure you have the correct eyeglass prescription. 2. Every 20 minutes look at a point 20ft away for 20 seconds and blink 20 times. 3. Get a pair of computer glasses that filter out blue light. Gunnar makes good computer glasses, and your optometrist probably has a coating that has the same effect. 4. Place a light behind your monitor. Source: semester long report I had to do about Computer Vision Syndrome. It's totally possible I got some things wrong since Im on mobile and don't have my report handy or access to the journal articles I used to write it. Edit: [Here is a pretty good source on Computer Vision Syndrome]
Why has pizza delivery in "30 minutes or less" become uncommon?
About 20 years ago, there was a multi-million dollar judgement against Domino's when a woman was hit by a pizza delivery driver who was not operating the vehicle safely. This caused a lot of bad publicity for the "fast pizza delivery" deal, and as a result Domino's dropped it's "30 minutes or free" guarantee, and other pizza companies backed off delivery guarantees as well.
Why are Mountains triangular in shape (or at least similar to a triangle
It's the result of gravity and erosion. Mountains are shaped over millenia, and in that much time the force of wind and rain wears down and breaks apart the rock that makes up the mountain. As the mountain crumbles, gravity shapes it into a rough cone: the mountain falls away radially around the peak. The "triangle" image of a mountain is because looking at a cone from the side looks like a triangleWhen you crash two sheets of paper from opposite direction they will collide and form a triangle.Upper crust of earth is like a sheet of paper colliding into each other.
Why are donuts considered a breakfast food?
They are highly caloric and sugary, so it's best to eat them in the morning because then you're active for whole rest of the day and you can burn off that excess energy from the sugar and burst of calories.
Why detox water if I am already having fruits, veggie and drinking water everyday?
Detox is a scam. Your body does not accumulate "toxins" and there is no amount of drinking/fasting/pooping you can do to "detoxify" anything.They are making money, pure and simple. Why don't you read up on groups of people who live longer than average and imitate their diet?
In uncertain times, is it better to have your savings in the form of money? Or precious metals?
during recession - currency during extreme meltdown of society - precious metals', "If you honestly think civilization is going to collapse, gasoline, food, and water would be what you hold. Precious metals won't amount to anything more than paper currency would. Now, if you aren't pushing the fringe panic button, having money isn't going to hurt you if economies weaken in an extreme recession. It may not have the value it did today, but entire nations aren't going to convert to some other exchange of currency , simply because that was what was used in the past.If you are on your own and mad max maniacs are afoot what good is gold? It just sits there. Tools, supplies, gas, things with intrinsic value are where its at if the fit hits the shan.
What getting a "tune-up" on your car consists of.
The basics of a tune up are fluid changes of a majority of components such as oil, trans fluid, brake fluids, power steering, coolants, and window wash fluids. The filters for the components should also be replaced at the same time. Spark plugs should be checked and depending on the carbon buildup they may be changed or just be gaped. Most places check brake pads and rotors, wheel alignment and wheel balance are recommended if you want a perfect ride. The only thing you can check yourself would be the fluids. You can check the oil dipstick and measure how much oil you have as well as the power steering. If your going to check your coolant make sure the car hasn't been driven for at least 20 min because the heat build up causes the fluid to expand and its extremely hot. I would recommend you wear eye protection from rust and fluids Brakes should be done in the shop because if anything goes wrong you can mess your breaks up and you can get into a car accident.
Surrogacies...if Donor A fertilizes Donor B's egg, and it's implanted in Donor C, does the baby have any of Donor C's genetic characteristics as a result of the incubation?
Genetic characteristics? No, not as such. The surrogate does not contribute any genetic information to the zygote. But does the surrogate not matter at all? I think that might be too much to claim. If nothing else, the womb environment in a surrogate mother will be at least ever-so-slightly different from that in the womb of the woman who supplied the egg to be fertilized. This is important. DNA isn't computer code, i.e., the same genetic sequence will not always produce the same physical expression the way you always get the same result if you execute the same section of machine code. External stimuli contribute to the way that cells implement genetic instructions, either by the introduction of errors or simply because the code doesn't spell out the result with exactitude and leaves some portion of the final product to chance. For instance, even identical twins are usually at least a *little* different in appearance, and that difference is attributable to environmental differences that the twins experience because they are not numerically the same person. Given that, it seems reasonable to think that an embryo that gestates in Donor B's womb would have at least a *slightly* different outcome than one in a surrogate's womb, even if the resulting baby doesn't actually have any of the surrogate's genetic information on board.
Student loan jargon. Read the papers, still confused. (So much for a college education right?)
Head to your local bank or credit union and explain your situation. With a 4-year degree and steady job you should be able to get some decent refinancing options. You'll pay a higher interest rate on your debt, but you should be able to take your monthly payments down significantly.
Why when I'm tired do I turn the TV down really low, but I'm still able to hear it?
It's a combination of factors. When you're tired, you're not up and about causing noise in your immediate vicinity or distorting the sounds of the TV by moving around. You also lose your capacity to focus on several things at once when tired; you're focusing on the sounds coming from the TV and not simultaneously juggling some thoughts about your day, or diverting your gaze to another happening. Have you ever heard that tidbit about how blind or deaf people have heightened faculties as it pertains to their working senses? I think the concept is similar here.
Why we are told to consume some medicines before food and some after food
As well as the gastrointestinal pH affecting drug absorption some drugs are purposely given with or immediately after a meal to slow down absorption or to provide short term protection against the acidic nature of the stomach contents . Drugs mixed with food pass into the small intestine more slowly than drug mixed in stomach secretions alone. For some drugs it is necessary to control the rate of absorption to stop large quantities of the drug entering the blood stream quickly and giving what are known as peak plasma level side effects . Slower absorption from mixing with food can still let the same amount of drug into the blood but the levels do not get so high as those that cause the nausea and vomiting experienced by some patients. This is a very simplified picture .
Why do soap operas look the way they do? What is the camera/production technique that makes them look different?
nice video of a side-by-side comparison of it on and off. _URL_0_They're shot at a higher frame rate. Even some newer TVs try to up the frame rate of movies from 25fps or so to about sixty and it also gives that "cheap" appearance. Here's some more info on the soap opera effect. _URL_1_
Power generation -- please help me to understand the 'monthly average real-time locational marginal price for energy at the commercial node.'
So the monthly average real-time locational marginal price for energy at the commercial node is quite a mouthful, so let's break it down. Monthly average is pretty easy to understand the average price for the month. Real-time refers to the energy demand for a specific time period , and then the price associated with it. Location of the marginal commercial node refers to the power plant that services your subdivision/region. If I am understanding this correctly you can essentially get some money back by supplying energy at the same rate that it would cost the power plant to generate the energy at the time, so giving more during peak commercial hours would net you more money than late at night when there are less people using electricity.
How do companies determine the cost of acquiring a customer?
1) Time and material spent on sales & advertising. If you spend $1 million on an advertising campaign and it averages 10 new customers, then that's at least $100K to acquire the customer. 2) Time & Material getting the new customer set up. This covers any kind of material that you have to give the customer , the time it takes to create the customer's back-office information , and any time/material it takes training the customer on the use of your service before they can start giving you money on a regular basis.
Why do businesses with double doors usually only unlock one?
For the same reason a lot of convenience stores and gas stations modify their doors to be harder to push open . It makes it harder for people to run out and take off in a snatch-and-grab or other criminal situation. You'll especially notice this in pawn shops that have two sets of doors and a little hallway in between -- they'll usually unlock only the doors diagonal from one another so that anyone who runs out has to go through one door and cut across to the one diagonal from it. This gives security more time to respond and apprehend.i manage a shopping mall, and the reason we keep one locked is to keep the cold air in or out . Why bother having double doors then? well, first of all, just a single door entrance into a mall would look kinda funny, and second, for when we have to move stuff bigger than 36" in or outYes, someone please explain why business owners feel the need to make me look like a jackass when I go slamming into the wrong side of a one side locked double swinging door. Do they do it for the lulz?', "Well, it remains locked for the safety of the store's assets. As others have said it deals with loss prevention. Sure, you look like a total idiot whenever you push or pull the wrong door, but it helps the store in terms of thieves. Once, when working a retail location, there was a guy in the store who attempted to shoplift one of those personal hotspot devices Except we noticed him and he tried to go out the locked door which gave us just enough time to stop him. Pro-tip: if you're robbing a store, remember which door you came in.
How can a hash, resulting from a fixed-length algorithm, always generate unique results if there are a limited number of possible results, but much more inputs?
No, you're definitely correct. Because you can hash a message of any length down to a hash of a finite number of bits , there are an infinite number of hash collisions. Part of the "security" of the hash is how difficult it is to go find a collision. A huge focus of modern cryptographical research is to find ways to collide hashesThe simple answer is that hashes *aren't* unique. That does, in theory at least, mean that if you chose to set your password to something really secure - incorporating a decent number of characters, symbols, numbers, mixed case and so on it could in theory have the same hash as "password", meaning that someone could get by it by just typing "password" at the prompt - but the odds of that are pretty damn remote.Duplicates are possible. It doesn't have to be unique, it just has to be sufficiently hard to crack. There could be two different strings that hash exactly the same way. But that doesn't make the system any less secure, because it doesn't help you to find an unhashed string from the hash.
The whole Charlie Manson/Manson family thing
Charles Manson was a serial killer. But instead of killing people himself, he had his "family" do it for him. He brainwashed/manipulated/indoctrinated a bunch of women . They loved him and would do anything for him. Well, "anything" meant killing people, so they did. He's currently serving life in prison.
Why do our bodies rock back and forth when we sit?
Redistributing load on muscles and joints prevents harm and aches that would occur more frequently in a prolonged loading scenario. tl;dr feels good man
Why spicy foods don't lose their heat when they're deep fried if capsaicin is fat soluble?
Two reasons. First, the oil is never in contact with all that much capsaicin. Most of it is in the food, behind batter, or behind other capsaicin particles. So even if the oil does dissolve some of it, there is still a lot of capsaicin that is inaccessible to the oil. Second is kinetics. Soluble molecules can take their sweet time getting into solution. Try dumping a spoonful of sugar into room temp. water. The sugar will dissolve entirely, but not quickly.Fat soluble doesn't mean fat will come and suck every single drop of something out. It would at best wash the stuff off the surface and basically do nothing to any of the stuff inside the object", 'The capsaicin has to have contact with fat in order to be absorbed by it. Deep fried things with capsaicin generally only have their outer layers touch fat, and most of the time that is protected by badder.
Why aren't rich nations closer to Syria, like Saudi Arabia and United Arab Emirates being pressured into taking in any refugees?
It's hard to pressure a country that beheads people for sorcery in 2015. They aren't exactly rational actors.
How is it people find out which towns are doing events on certain nights (trick-or-treating/fireworks a day early/late)
Once upon a time, in an age before computers, people had to figure out a way to share information and let the town know about events. These were dark times and information was hard to come by, but every morning a boy on a bike would drop you off a bundle of information that would tell you about what had happened and what was soon to happen in your local area. There would be spots for upcoming events in all the near by towns so you'd know about events without just talking to people In the era of light and information it's now often posted on the town website or Facebook page, but many still get that bundle of news dropped off on their doorstep every morning TLDR - Newspapers, but now Facebook too
Why do some planes leave a trail of condensation/mist behind? What causes these trails?
It is water vapor. When the engines burn fuel, they put out exhaust gases, and part of these gases is steam These Con-Trails are made up of water particles put off from the exhaust of the jet engines. 30,000ft up it is very cold, so when the engines burn off fuel, it heats and vaporizes what water is in the air. That water, then turns to steam and is released in visible trails behind the aircraft as it flies through the air. Since there is such a distinct temperature difference in the trails, the water quickly evaporates back into the air becoming water vapor again due to the relative humidity and temperature of the environment.
why does a car driving through the hot sun not get as hot as a car parked in the hot sun?
Convective cooling.\rThe shell of a moving car is going to be air temperature mostly while a stationary car since it has much less convection can be quite alot warmer.
Why is Slovakia's capital at Bratislava at the outskirts of the country?
Slovakia wasn't always Slovakia. It used to belong to the Austrian-Hungarian monarchy, later Czechoslovakia. Bratislava has always been an important centre for education, religion, bureaucracy, trade etc. so when we became independent, it was chosen to be our capital. Also, it's not like we're the only ones Ottawa, Washington or Canberra aren't that "central" either just to name a fewFun fact: Bratislava and Vienna are the two closest European capitals.Because the most of the cities in Europe are waaaaaaaaaay older than the countries they belonged to. The borders change, but the citie's influence only grows. It just happens its proclaimed their's capitall.
What were the Yugoslav wars about and why was America involved in them?
If you want answers to questions like this that are "unbiased" and without conspiracy theories, one of your absolute best bets is to submit your question to /r/AskHistorians. They have very strict journalistic integrity and the moderators take it very seriously. Jokes and quack stuff gets deleted almost immediately.The wars were about the disintegration of Yugoslavia due to attempts by Serbia to control Yugoslavia and to promote Serbs as the favored ethnic group. During the wars that followed the breakup of Yugoslavia, Serbian paramilitary groups funded by Serbia began ethnically cleansing ares of other ethnic groups - mostly through targeted violence like killing some of the males, burning down houses, and otherwise just driving people out of the Serb controlled areas. After the fall of Srebrenicia, Serbian forces murdered about 10,000 military aged Bosnian males. The US had been trying to stay out of it to that point, but after that NATO decided to provide military support against the Serbian paramilitaries to try and force them to the peace table, under a peace-keeping and 'responsibility to protect' doctrine, that says the Western nations should be willing to use force to prevent atrocities and war crimes. The US and NATO, in addition to airstriikes, helped arm and train Bosnian and Croatian forces. These forces then launched a counter-offensive in 1995 that pushed many of the Serbian forces back and turned the tide of the conflict, and led the Serbian forces to come to the peace table. After the signing of a peace treaty, NATO forces deployed into the country to keep the peace. It was initially about 60,000 troops and has gradually drawn down; in 2004 it was handed over to the EU and American involvement mostly ended; right now there are only about 900 troops, who also help look for war criminals from the civil war era.
Why do scrapes and other injuries feel more painful when its cold outside?
When it's cold, your body draws blood in from the limbs to conserve its warmth by constricting the veins in those limbs. This causes the skin and flesh to press on the nerves, increasing their sensitivity.
How was it possible that OJ Simpson was not charged with either murder when the prosecutors had such compelling evidence against him?
Charged with means the prosecutors formally begin a trial. OJ Simpson was charged with the murder of Nichole Brown Simpson and Ron Goldman. He was not convicted, meaning the jury voted unanimously that the prosecution could not prove its case beyond a reasonable doubt. Some of jurors have provided details in [books] ) about their reasoning for coming to the decisions they did. They appeared to have substantial concnerns about the evidence collection and handling practices of the police .
So humans regenerate skin cells and all, and that's cool, but if we constantly make new skin cells, why do I still have freckles, when birthmarks might fade over time?
Because freckles are constantly being created as the melanin in your skin reacts to the sunlight Whereas a birthmark is more of a 1 time event and can be "overwritten" with fresh new cells. Much like a scar
What is a web scraper and what can they be used for?
A web scraper is a piece of software that goes to a website, grabs pages & then parses out the interesting/useful data. Let's say you want to follow the price of items at Amazon - your web scraper would request the page, find the item name & price and return that to you in a clean, easy to work with format. Some of them get more complicated because you have to handle form submissions or horrible HTML but the idea's still the same - an automated tool to extract information from a web page. These days, most sites that *want* you to have their data have some sort of public API for getting just the info out ). Scrapers are still needed when you're trying to get information that people don't really want to hand out or they're just too cheap/lazy to provide a clean view of the data.
When they say that we move at a finite speed through space-time, what are the denominator and numerator of the rate?
I think what you're asking for is what units we use, as in "kilometers per hour". If that's correct, you could separate the space and times components and say "meters per second" for space and "seconds per second" for time, although this is simplistic. This may not be the best ELI5, but I'm not sure how else to explain it without talking about things like worldlines, relativity, and proper time, which are definitely not ELI5. You should ask this in r/askscience. You'll probably get a much better explanation.
Why do Homeowner Associations hold such tremendous power?
HOAs are entirely voluntary. If you don't want to join one, you simply don't purchase property governed by an association. That'll be pretty hard to do if you want to live in a place with shared property , but it's quite easy if you want to live in a house. There are plenty of horror stories about HOAs on reddit, but the good that a lot of them do goes mostly unnoticed.
Keep Calm and Carry On
I don't think those particular posters were publicy used, but they were certainly prepared and would have been used, I think, in the event of an invasion. They 've got popular because they're pretty indicative of the British attitude towards any crisis - not to fuss or panic, just tut and go about our business. They also lend themselves to amusing variants, such as "Now Panic and Freak Out"
Why is the news of China cutting domestic interest rates causing the U.S. stock markets to surge?
Mainly it's that people who were investing in China are seeing the lower interest rates as indicating lower returns on those investments. Those investors pull money out of Chinese investments and put it in US investments instead. That causes the US market to surge since there are many buyers
Was WW2 propaganda (posters, movies, etc.) blatantly and widely referred to as "propaganda" at the time or is that just the description we give it in retrospect?
The enemy's propaganda is always called propaganda. Although, its interesting that the word didn't always have such negative connotations. The root of the word is the same as 'propagation', and it began in a religious context. Even as recently as WW1 the British would charmingly refer to their own propaganda coming out of the Ministry of Information, though lately the use implies a negative.Same as today, find something like "American Sniper", you will see tons and tons of stuff that does call it propaganda but it's not like the poster says \'come see this new propaganda!"
What is the unit of viscosity and how is it measured?
The SI unit is the Poise, and it's measured by applying shear stress to the liquid. A typical viscometer has the liquid sandwiched between two concentric plates that the fluid sticks to, and measures the torque needed to turn one of them, then you calculate the viscosity from that. The plates can't be smooth, of course - the liquid needs to stick, not slide over them. There are different types of viscometer.
How will this "businesses can buy your internet history" work? Can you buy an a specific persons?
No, you can't buy Donald Trump's browsing history. There are very few people for whom there would be a market, and they would sue the ISP. What you will be able to say is I have two versions of this ad, A and B. If someone goes to more republican sites than democratic ones, when you get the URL for my ad, put up version A. The other way around, put up version B.
How are chip-readers more secure than magnetic strips?
It's not necessarily the reader, but the card itself. In an eli5 sense, a magnetic stripe says "I am X" when swiped. It is extremely easy to create a copy of the card that also says "I am X". A chip card, when read, initiates a conversation like "If you say you are card X, please complete this math problem using your secret ID number and give me the result". Because the whole card's information is not transmitted during a transaction, it is much harder to create a copy. If a second authentication factor is not used, chip cards are still weak to physical theft and malicious usage of a card, neither do they protect against fradulent online usage.If done correctly, they are chip+PIN. You need both the card and the number, that is how it was developed initially. Even without it, it's slightly better because a chip card is a bit harder to clone than a normal card.
why can't we bundle our health insurance with our other mandatory insurances like car, home and renters? Or even combine it with life insurance and other insurances?
There would be no real benefit. The money you pay for your car and home insurance premiums doesn't go in some account with your name on it. "This is Yolo20152016's unused insurance money" It goes towards the profit and operating costs of the insurance company. Most importantly It pays the claims of other people that also have insurance. Poof, it's goneCar ins. Really bugs me. I think it should be set up different. I am 67 years old. I have never made an ins. Claim. Really never. Yet I have to pay 160. A month to insure a 1998 and a 2000 car. PL & PD only. A lot of money to me for absoutly nothing. Last year I got rear ended sitting at a stop sign waiting my turn to pull out. Totaled the rear end, rear side panels, trunk lid. $3000. In damage. Guess what, the guy who hit me did not have any insurance. Could not even get the $1000. Torte coverage because he was not insured. On and on it goes.
Why don't horsepower and torque correlate? ELI5
Horsepower and torque do correlate. The formula for horsepower is: HP = / 5252 "Horsepower is torque corrected for RPM."
What happens to all the extra food in shows like "MasterChef"?
It depends on the show. Usually, the crews get first pick of the food. MasterChef specifically donates leftovers to OzHarvest, and many other shows have similar arrangements with charities. Iron Chef would let the chefs take home food, so occasionally competitors would "accidentally" open packages containing expensive ingredients and then take them back to their restaurants.
What is a Flexible Spending Account, and how can I take advantage of it?
I'm going to assume you're talking about a medical flex spending account offered to you by the company you're working at. If that's not the case, feel free to ignore me. These are accounts that you can send a certain portion of your money each paycheck into tax free. The trick is that this money can only be spent on certain things . The basic idea is that you don't pay taxes on money you spend on medical expenses. Flex spending accounts help you do this quickly and easily.
My Almost 5 year old brother wants to know what the internet and a website IS
The internet is a bunch of computers, wires and software all working together. Some computers do different kind of things. A website is a page that is written in a special language so people can show videos music write things and show cool applications. To get to a website we use a web browser that talks to computers that are especially made to find things You can send this request by either typing in a websites address directly or using a search engine that will help you find it. That shouldn't be too hard to understand
Seeing as mosquitos are some of the biggest threats to continued human development, would there be any significant consequences to driving them extinct?
An analysis I read about this had a basic "not anything drastic" as an answer. They are a major component of the insect food chain and they don't heavily compete with other insects for their food so many mosquito-eaters - bats, fish, dragonflies - might have reduced populations due to a reduction in their food supply. And they act as disease carriers to species other than humans , so some animals would be less affected by them. Finally it might open up options for less protected animals to move into mosquito-rich areas such as the northern tundra because they 'd no longer get eaten alive there, as mosquitos can actually kill animals through bloodloss if enough of them feed. But these wouldn't be enough to bring the overall food chain to its knees. Some species would suffer more than others, but eventually something else would either just move into, or evolve to fill, their ecological niche.
How do lobbying groups control advertisers?
Usually lobbying groups are advertisers themselves, as in, they pay to have a commercial made supporting a certain opinion or conversely they advertise the hazards of a certain action .
Why do different operating systems require different versions of the same software?
Software developer here, There is a thing called a system call, and this is basically the program asking the operating system to perform some work, for example, reading data from a file. A program doesn't know how to do this, it's not part of its program to know what a hard drive is, or how different manufacturer hard drives work, or what a file system is - all that is abstracted away. Most operating systems offer a fairly standard complement of system calls, but there are minor variations and different conventions behind how they are called. The majority of the binary instructions in a program from one OS platform to the next will mostly be the same for a given hardware architecture, but program setup, tear down, and when the program has to reach outside itself for resources, these things are different between operating systems.
Do air marshals really spend most of their time flying around in random planes? How are they assigned? Or is that just something for the movies?
The Federal Air Marshal Service is part of the Department of Homeland Security. They are trained law enforcement officers who train specifically around planes/aviation. They go through the Federal Law Enforcement Training Center , which all federal LEOs go through, and a secondary training specific to their role. They are assigned to specific flights, both domestic and international. Long international flights can have multiple Marshals on board. The flight crew knows of the Marshal's presence on the plane. The agency chooses which flights to have Marshals on board. They tend to increase if a large sporting event is taking place or a major political event is occurring in a city. If you fly frequently, you probably have been on a flight with a Marshal and never knew it. Edit to answer a few more items:Much of their time is spent in the air or at airports, but they also can have desk work.They carry SIG p229 chambered in .357 Sig. For those not familiar, it is a hybrid between a 9mm and .40 . Think 9mm magnum for the easiest description.
What does our body use trace metals (eg: iron) for?
Iron is used in haemoglobin, for binding oxygen in our erythrocytes . Magnesium is used as a regulator in hundreds of biological reactions in the body. They are mainly used to help other reactions either happen at all, or progress faster.
if public IP addresses are dynamic, which means they are constantly changing, how is internet activity able to be tracked, logged, etc.?
Dynamic IPs aren't really all that dynamic. You keep the same IP as long as you renew your lease every 2-3 days. Some systems may give you even longer before recycling your address. Beyond that, it's not unlikely that your ISP logged the information about who was assigned the IP & still has the data sitting around.In order to have internet service your Modem has a unique address called a MAC address. When you are assigned a Dynamic IP it is logged by your ISP as being assigned to your MAC address. Your IP address can change completely, but your MAC address for your modem will never changeISPs, your providers are required to keep records/logs of what network device aka customer had what IP address in time.
Why do video game companies make games that you can't pause offline? Mainly zombies in black ops 3
To make the game more tense. They could easily add pause, but but bring able to gets some people more immersed. Dark Souls did that to me.
Can you briefly explain Dr Who?
Doctor Who's main character is The Doctor himself, he is a Time Lord and he nicked a time traveling spaceship called the TARDIS . The Daleks are a genetically modified race that lost the ability to feel pity, compassion, or remorse and they consider themselves a superior race and have a desire to "purge" the Universe of everything non-Dalek. The Time Lords had a huge war against the Daleks called the Time War where their home planet and their race got destroyed , and the Doctor is the last of the Time Lords. He travels around, has adventures, both in the future and the past, both on Earth and on non-human planetsThe Doctor is a time-travelling alien. He travels in a TARDIS . The TARDIS can travel through time and space. He goes around solving problems and fiddling around with situations as he finds them, often with one or two companions. The Daleks are a race of highly aggressive, cyborg aliens. Their modus operandi is to kill everything that isn't a Dalek while screaming "EXTERMINATE!" in a very loud and repetitive fashion. The Daleks are mortal enemies of the Doctor, as the two races fought a very long and drawn out war over the fate of the universe.since the other comments nicely explained it, I'd also like to add that you should try a few episodes yourself. it's meant to be suitable to an adult audience as well, though it may take a few episodes to get into. most of it is quite enjoyable to watch, compared to pretty much any other show suitable for children.
How is it that the distance between Earth and the moon can supposedly fit all of the planets, but pictures show the moon relatively close to Earth?
[Well here's a picture of the Moon and Earth drawn to scale.] Most of the picture is just black space, which is useful in situations like this where you want to gauge the distance between them, but for most illustrating purposes you usually just want to show the two bodies together with the moon slightly further away to represent orbit. Distances in space are *crazy.* [This is a map] showing the distance of planets and moons in our solar system, scaled down so that the moon is displayed at a size of 1 pixel. Since that's the smallest a computer monitor can show, this website is the smallest map of the solar system that can be drawn at scale while still showing the moon. That's why we usually have to get a bit abstract with the pictures, because any scaled map of celestial bodies is going to be almost exclusively empty space.
tea bags in the US politics
There is a party in American politics called the [Tea Party]. Making fun of them by calling them tea bags tea baggers. I can elaborate on tea bagging if you want.
how long does person have to be dead before it’s considered archaeology instead of grave robbing?
It is not a matter of time, it is a matter of intent and legality. A graverobber illegal takes objects from graves to sell them. An archaeologist legally takes objects from graves to study themIt depends on who owns the burial site. Archeologists must get permission from the landowner and get an excavation permit from the government. Grave robbing is a crime, so no permission necessary. What must be done with any finds are dictated by the laws of the country. The IS has the Native American Graves Protection and Repatriation Act, for instance. In Switzerland, all "ancient artifacts" found belong to the state, though the finder must be rewarded. Archeologists worked on the site of the 9-11 attacks on the World Trade Center, and their finds are on exhibit at the 9-11 museum.I don't know as a whole but there was a case of someone retrieving a well preserved and *ancient* native american body that was eventually returned to to contemporary native american people, so in some cases it seem like an indefinite amount of time.
What makes the Millennium problems so difficult?
There are several different types of problem there. Like any problem the solution seems hard until someone figures it out the first time. Unless many people try and nobody comes upon the key. Then they get noticed, and in the case of the millennium prizes, they get collected together and publicized by people willing to pay just to know someone has solved them. More directly, it's usually a case of there not being the right kind of math invented to solve them yet. Which is another way of saying we can logically understand the question but we can't symbolically get from there to the answer. Until someone does. And then we add a course to graduate science or mathematics programs and move on to wondering why we can't solve the other problems so simply
What do Ant & Roach killers that kill on contact such as Ultra-Kill or Raid actually do to the ants?
It is a matter of debate whether insects like ants feel \'pain\' in the sense that we do. Their nervous systems are much simpler and, in a lot of cases, much more autonomic than ours. Cockroaches have [hairlike appendages on their bodies which act as sensors] and detect air flow changes, alerting them to impending danger; the impulse to run moves directly from these sensors to their legs without traveling to their brains, which is why they're so fucking fast to zip out of the way of a shoe or newspaper. Flies and many other insects are similarly equipped. As others have explained, the sprays and foams act as nerve agents, disrupting the insects\' nervous systems. What you are interpreting as "writhing in pain" is more likely just their nervous systems misfiring as they collapseRaid paralyzes the nerves of insects. Nerve paralysis for more than a minute means death from any number of things.I was actually wondering this the other day as I sprayed a cockroach. In the end, what's important is that the fucking thing suffers as much as possible before it does forever
Rational Emotive Behaviour Theory or R.E.B.T
It's a form of [cognitive-behavioural therapy] that espouses rational, logical thinking, flexibility, and acceptance as the antidote to dysfunction . Essentially, the practitioner is there to help the client challenge self-defeating or harmful perceptions of a situation situation, examine evidence of a particular assumption more pragmatically, and then gain insight from the unhelpful understanding of the situation. Unlike "pure" CBT, which sees the thinking/feeling/acting parts as relatively independent parts that influence each other, REBT sees thinking/feeling/acting as shades of the same thing. It's pretty trendy right now, but of course it has many of the same criticisms of CBT. The Albert Ellis Institute [has lots of info.]
Whats the point of circumcision?
This is an episode of Penn & Teller - Bullshit - Circumcision. _URL_0_', "These days it's mostly about religion and social norm. Some people say it's because of cleanliness, but there is really no problem in cleaning an uncircumsised penis. There is also the argument of cutting it before any potential problems with the foreskin appears.
How does VLC remember where you were last watching?
The Mac version uses a dictionary called recentlyPlayedMedia in its preferences file. Each entry contains the file path and the time offset in seconds.
Why does audio rapidly repeat itself when a computer crashes?
At a high level, sound cards playback sound by reading digital data from a buffer and converting it into an analog signal to transmit to the speaker. When a normal stream of audio is being played back, its data is written into the buffer as a stream so there's no hops or skips - as the digital audio converter scans back and forth over the buffer, the buffer data is overwritten as its being played. If the audio controller crashes but the hardware is still going strong, it begins to simply replay what happened to be in the buffer at the point of the crash, causing the effect you describe. The audio will fully stop if the OS can catch the program going unresponsive and eject it from memory, which frees the audio controller.
What is a magic eraser and why does it work?
It's melamine foam, which is a really hard material made into a sponge. It's basically really fine sandpaper, so be careful what you clean with it .
How is it that we are the most advanced species on the planet, yet our young take so long (much longer than most species) to be self-sufficient?
That's just it. It takes a while to amass information and use it. An animal just does whatever comes natural, aka 'instinct'. But humans are taught and trained and learn and practice and and Layers and layers of information and training to get us to the point where we can actually achieve more than the previous generation. None of that comes easily, nor quickly. For to run, one must learn to walk. Apply that to any activity in life. Building. Theorizing. Testing. Proving. All these require layers of previous knowledge. For we are not animals, just here to eat and procreate. We are more than animals. But it takes practice to stay that way. Years of it.
wtf is a 'noun clause'' and why would I use it?
It's a dependent clause that acts as a noun. For example: "Whoever thought of that idea is a genius" The noun clause in that is "whoever thought of that idea" this entire phrase is subject of that sentence.
Why are earthquakes with a high magnitude appearing frequently?
They're not? Earthquake frequency has not noticeably increased. Here's [all 7.0+ earthquakes in the last 5 years]. They're pretty evenly spread over that time. Yeah, there were several big ones today, but random events clump up it's the nature of randomness.
What does one have to do to be able to make a subreddit
You have to have a 30-day-old account and an amount of positive karma. You basically have no karma at the moment, so I would say that you should comment on some threads to build it up.What sub do you wanna make? I'll make it for you, and you can be a moderator
Why are people so against ResponsibleOhio's plan for marijauna legalization?
The main complaint is that it arbitrarily limits the production and sale of cannabis to 10 state-chosen companies. This is good for the state but bad for consumers Imagine if the government, coming out of liquor prohibition, had made it legal to drink alcohol again, but only let Jack Daniels and Budweiser make it. In the eyes of the government that would be great, because they 'd only have to regulate two companies, and those two companies could operate more efficiently and thus have higher, more taxable profits. Most drinkers on the other hand would view it as an unfair handout to those companies and an entrenchment of their monopolies. The city of Oakland, in California, ran into a similar issue a few years ago when the state was first really looking into legalizing. They announced they would only let 4 companies grow for the entire county, in massive indoor factory farms with huge tax-funded subsidies. A lot of local medical growers would have been out of work to these huge companies, and the fallout from that plan in large part led to the failure of the ballot proposition that would have made California the first state to legalize recreational use. TL;DR: Many cannabis users / growers / sellers view the current plan as too limited, and dislike that a handful of large corporations would hold a monopoly in what has so far been an industry dominated by smaller local growers.
How come this scan of the chromosomes are in multiple colors?
False-color image. Its colored with the intent of making parts more easy to tell apart, to highlight certian features, etc. that would be unclear in just its normal color. Edit: here's a good example: _URL_0_ Normally it'd be very tricky to see which mountains were which sizes on a picture of Mars. but using false color it becomes obvious.
Why are Gatling Guns called "Miniguns"?
The "Mini" in the name is in comparison to designs that use a similar firing mechanism but larger shells, such as General Electric's earlier 20-millimeter M61 Vulcan, and "gun" for a caliber size smaller than that of a cannon, typically 20 mm and higher."Minigun" refers to a specific model of weapon that General Electric originally produced, but the term "minigun" has popularly come to refer to any externally powered Gatling gun of rifle caliber. The term is also used to refer to guns of similar rates of fire and configuration regardless of power source and caliber.
How is the blood from meat removed before it goes on sale?
Blood is removed by hanging the animal upside down and draining it. Muscle tissue contains very little blood anyway. Blood rots much more quickly and hosts many nasty diseases without the living host. Also it can it used extensively in the medical fieldthe animals are killed, then hung to let the majority of the blood drain, then the animals are skinned, gutted, then washed and then butchered into cuts of meat.. [my source.. a pretty thorough rundown]
How The Geneva Convention relates to war crimes.
The Geneva convention exists to stop war crimes. Lets say I was a nation, and I declared war on you. My troops massacre some civilians, or I use WMDs, The Geneva convention exists to stop that happening. Simply put, the Geneva convention exists to stop cruel or excessively damaging , and guarantees Prisoners of war fair treatment. A war crime is when a nation's military breaks the rules laid out by the Geneva convention.
How do some people operate on such little sleep?
Being in the army for a while I'm use to running on 4 hours or less of sleep and still doing 16 hours a day.
Why is YouTube getting steadily worse?
I'm sure there is someone who can explain it better but I'll try. Youtube uses DASH playback, it loads the video you watch in chunks. When you watch till a certain point, they will load the next chunk. What it does is save Youtube bandwidth so they won't waste it when you buffer the whole video but only watch part of it. At least, this is to my knowledge on how the new Youtube buffering works. What you can do is install Youtube Centre on your browser to disable DASH playback but you will be limited to a maximum video quality of 720p, which I find rather acceptable. That way, you can buffer the entire video then watch it, instead of having to pause and let the video load every few seconds when on a bad internet connection. I am no expert but this is what I could gather. I hope it helps!", 'It's the "not available on this platform" that confuses me, why is a video watchable on a PC but not a tablet?', "Why do the Ads load/buffer without any wait but as soon as you try to watch something you can't play it till it loads. :(", 'ALOT of legitimate users are being ghosted in the comments not by channels but by the google spam filter, if you comment too much now on youtube or reply to comments too much you may get ghost banned from every channel for a period as youtube thinks you are a spammer not matter what you are saying. Ghost banning means you can see your comments and replies but no one else can. Originally this was intended for channel owners but since the google+ merger and subsequent updates its now being used on entire accounts resulting in people thinking they are being ignored even if they had valid points or creative input to a subject in the discussions. To see if you are ghosted post a comment on youtube or google+ then log out and see if still there, suprisingly this is becoming more common and in reply to your question its rather simple, google bought youtube
Why do balloons explode, there is a loud sound like gun shot?
The air is under pressure in the balloon, because the skin of the balloon is tight. When it pops, the compressed air starts to expand. This generates a compression wave, what we call sound. Guns burn gunpowder in a confined space, and when the bullet leaves the barrel the pressure is released in a similar sound wave.
What's happening when you want to sneeze but just can't get a sneeze out?
You become aware of the sneeze before it happens which puts you into manual mode, you consciously try to finish the sneeze but you don't know how. Kinda like when you start breathing manually but the difference is that you don't know how to sneeze consciously so you just stay with a half sneeze face and that feeling of dissatisfaction.
Why are they still making cars with manually rolled up windows?
They: * break less often * Are cheaper to fix/replace when they do break * Are cheaper to produce * Are cheaper to fit into a car Inexpensive maintainability isn't always the selling point car manufacturers go for, but it's certainly a selling point .Many people prefer manual windows because they are much less likely to fail and much less expensive to replace if they doWhy do they make anything but manual windows? How lazy do you have to be to need electronic windows?', "Because this allows a car company to have a 'base model' price which is as low as possible. This is the price used in the marketing for the car.Because they are Better. Flat out better. More Comfortable, better speed. More Control. They are less likely to fail. God! I hate motorized windows.
Why do some job applications require a questionnaire with the same "strongly agree/disagree" questions that make me feel like they're all trick questions?
They ask you the same questions in different ways to see if, after scoring, they were all answered the same way. "I don't lieIt's always important to tell the truthIf little Timmy asks if Santa is real, I tell him No"If you're not consistent, they score you lowerNot quite the same, but I remember I had a question like this that was phrased something like: "You see a coworker who is not working to their full potential due to a personal issue. Do you get involved?" I hated this question because the answer was simply Yes or No. To me, both answers are right or wrong, depending on the context. As a general rule, you should leave personal shit at home when you come to work. However, if your coworker is doing shotty work because of an obvious distraction, then it needs to be addressedMost are derivatives of the Minnesota Multiphasic Personality Inventory. _URL_0_ They are used to screen for jobs in law enforcement fairly often. They have been around since the 40's in one form or another. I have taken them many times over the years. The primary purpose of the test is to identify patterns in your responses. Allegedly, the tests can be quite good at uncovering the taker's "tendencies" towards a variety of psychological conditions/characteristics.
Why/how does covering a bomb with one's own body 'muffle' the explosion?
The most deadly aspect of a grenade is the shrapnel, the metal case of the grenade that is sent flying away at high speed, essentially thousands of little sharp metallic bullets. Jumping on the grenade is going to cause most if not all of that shrapnel to get sent into you, if any does manage to make it through you it will likely be traveling at less than lethal speeds.
How was the SHA1 encryption algorithm broken, and what does it imply?
The sha-1 collision attack exploits a weakness in the algorithm, allowing a input, that results in the same output, to be created far easier than brute force. The possibility of such an attack being used means that sha-1 is not a completely dependable method, and is essentially broken. With this attack, it is potentially much easier to create a malicious file/string with the same sha-1 hash as the original input. Many newer, stronger methods have been in use for a long time.
