why do many people frown upon folks who order steaks well done? | Imagine an apple. Large and juicy, full of flavour and nutrients growing on the branch. Think of it ripening, at some point it's at it's perfect levels of sweetness, crunch, and juiciness. Delicious right? Same with a rare steak. If you let it go too long, it loses the flavour. Loses the moisture content, loses it's te... |
Why aren't there separate sports leagues for people who do steroids/performance enhancing drugs? | Because doing so would encourage the usage of performance enhancing drugs and that's not something society wants. Using performance enhancing drugs to try and go beyond what normal athletes can do is already unhealthy enough, having athletes try and out drug other drug using athletes would be quite a bit worse for them... |
I've been seeing a lot of concerned talk about AI lately. Can someone explain to me what the big deal is? | So imagine you programmed an AI robot to protect your house from intruders. The robot could perceive this as - I will destroy the house so no intruders can enter it. - I will kill everybody in the world so there are no intruders. Combine this with robots for military use. Robots that can replicate themselves and giving... |
What is the significance of the blue color on the sheets of paper used for blueprints. Why not just make the plans for something on a normal sheet of paper? | Back when technical drawings were primarily made by hand, the most reliable way to reproduce those drawings accurately, with no distortion, and with nice crisp lines was to expose it to a photosensitive material, commonly colored blue not for any particular reason, blue was just the color of the chemicals used. This al... |
How do we feel physical sensations when dreaming? | Everything you feel is just your brains interpretation of the signals the body is sending it. The brain is still capable of interpreting feeling even if no singles are actually coming to it. So yes in theory your brain can make you feel anything, although how to make that happen is beyond our understanding at this time... |
Why does the sound of nails on a chalkboard bother my/anyone's ears so much? | The two main theories are: 1) The sound reminds us of the sounds/calls a lot of primates and apes make when they are scared, in stress or alarmed. It could be hardcoded in our DNA to react to this sound with negative emotion, stress and fear 2) The typical frequencies produced are the same that can give rise to resonan... |
Convolutions -- what exactly are they and what's the best way to think about them? | Although they are related there are a lot of applications of convolutions. It giving a LI5 explanation it would help to know what context you are getting them from. Good Luck |
The whole parallel universe conspiracy theory that is based on "Berenstain Bears/Mandela died in prison." | Because the vast majority of people, like me, remember it being pronounced Berenstein, rather than Berenstain, somebody has suggested that time was tampered with and we all remember how it used to be before history was altered. Edit: a word |
why do radio stations play the same songs over and over again? | Most people listen to the radio in their cars, and most people are only in their cars for short drives a couple of times per day. Playing popular songs ensures the most people will listen to that station, and playing the most popular songs multiple times per day ensures that the most people hear itTwo words: payola. Ra... |
Would crime go down if everyone (over 18) was required to have a concealed weapon permit? | Highly unlikely. To start, the homicide rate would sky rocket. What used to be bar fight or tempered feuds would probably end up multiple homicides. People attempting to stop a crime that does not justify lethal force would end up commiting the much worse crime of murder, or at least attempted. Not to mention other thi... |
How come cats are lighter than dogs of the same dimensions? | I'd imagine the bone and muscle of a dog is more dense. Dogs in general are bulkier animals when compared to cats. |
Why do some single symbols take up massive numbers of characters in a text message? | The character isn't really using 91 or 280 characters, but it's changing how all the other characters are stored. An SMS is 140 bytes long, and defaults to using a 7-bit alphabet which fits 160 characters in those 140 bytes . As soon as you use a character which can't be represented in that 7-bit encoding, the whole me... |
What is the legality in using copyrighted franchises/characters in youtube video to make money? | Any time you have a question of the format "Is *X* legal?", the only person who can answer that question is *your attorney*. Laws vary by jurisdiction.

what causes us to sleep talk? | During sleep the brain has to disconnect certain parts of it. It needs to be able to process what transpired during the day, form memories and dream. During dreaming it can experience hypothetical situations. Like in a simulation it can gain insights and run no risk. But to be risk free when having active dreams it mus... |
How do non profit organizations work? | Non-profits operate just like regular companies, they just aren't for the personal gain of a group of shareholders. They still bring money in, have expenses, and have a surplus or deficit at the end of the year. Just like regular companies, there are accounting and tax rules for non-profits. So if a billionaire donates... |
Are the refugees escaping Libya granted citizenship in the EU? | To be considered a refugee, one must prove that one will be killed, enslaved, or tortured if they are returned home. Under the EU charter, refugees are protected from 'crimes against humanity' - which by definition includes being returned home. Once someone has naturalised, there is little point in returning them home ... |
How can countries use grams for mass and weight measurements if they are different things? | They can't. Specifically, the SI unit of weight is the [Newton]. The confusion arises because laymen don't have a good sense of mass; high mass means something resists its acceleration . Weight is a _force_ that occurs on a mass in a gravitational field, and just so happens to depend linearly on the mass of an object .... |
If the President dies and the Vice President is sworn in and then later pardons himself before he reveals that he was the one who killed the President, what would happen? | How do you think he is going to pardon himself for a crime without telling anyone what it is? In any case, you can't pardon yourself.As long as the VP did not kill the President in DC this would be a state criminal manner. The President only has the power to pardon people convicted of federal crimes. He would be prosec... |
Why do goldfish grow as big as their surroundings? | They're large pond fish. When kept in bowls, they suffer from ammonia poisoning, stunting their growth before killing them. |
What is a non newtonian fluid and what makes them special? | Most of the other top level responses I see here are focusing on a certain type of non-newtonian fluid, notable shear thickening fluids like oobleck . However, as a general class, non-newtonian fluids are simply fluids that don't follow the Newtonian model of fluids. So: **What is a Newtonian Fluid?** Newtonian fluids ... |
How can heat dissipate in space if there are no molecules to transfer energy to? | Objects in space can still emit heat through infra-red radiation - that's what you see when you look at an object through an IR camera. Contact with other molecules is not needed.Everything above absolute zero emits some amount of light. That would be how a molecule in deep space would lose energy. |
Why are some animals much more aggressive than others? | Different species have found different techniques for survival. Some get food by attacking, others by sneaking, others by just eating plants. Some defend themselves by fighting, others by fleeing, others by hiding. Using a technique different from your competitors can increase your survival oddsAssuming you know how ev... |
What are a hedgehogs spikes/spines/quills made out of? | Hedgehog spines are just modified hairs, adapted to serve a defensive purpose. They are made of the protein keratin, same as your hair. Keratin is slow to break down, so is usually one of the last things to go when an animal decaysHedgehog spikes are modified hairs. They're made of keratin, which is that super cool stu... |
Why can't spaceships be fitted with a magnetic field generator to avoid solar radiation? | Generating a strong enough magnetic field to act as a shield has been discussed and theorized about for some time. However, as a practical matter, the power, size and weight requirements for using something like that on a spacecraft- and making it reliable enough for humans to use it safely- make it impossible with our... |
How do glow sticks work and what happens when you microwave it? | There's two chemicals separated inside. When you bend the glow stick you mix the chemicals together and a reaction takes place. The energy produced by the reaction is absorbed by a dye, an electron is excited and then releases that energy as light. If you microwaved it it'd probably only speed the reaction up , but the... |
How network provider can control my router and enable/disable wifi capabilities on my machine at home? | There's a set of special commands that service providers can send to downstream devices for configuration, software updates, and that sort of thing. Basically as long as your router is up, they can perform routine maintenance and configuration on it. |
How come the price of Oil went from 100$ a barrel to 27$ and the Oil price in my country went from 1,5€ per liter to 1,15€ per liter. | Suppose you want to make a grilled cheese sandwich. You go to the store and buy cheese , bread , and butter . If each of these cost $1, your sandwich costs $3 to make. Now suppose cheese is on sale for half price. The cost of your sandwich went down to $2.50, not $1.50 because the other ingredients still cost the same.... |
How do we instinctively know if something is good for eating? | It's not instinctive at all for humans. Look at babies, they put all sorts of non-edible items in their mouths. What's good for eating is a learned behavior. We learn from our parents/society what is edible and what isn't. > Give a dog and deer an apple. The deer will probably eat it as soon as he understand you don't ... |
How did Germany and Japan become allied as Axis powers? They are geographically far from each other, and have different languages and culture. | There are many ways you could look at the 'why' of the Tripartite Pact formed. To at least some extent, the Axis powers were meant to deal with the Soviet Union.The Japanese had a number of border clashes with the Soviets in the 1930s, and the Army had a distinct view of the Soviet Union as an existential threat to Jap... |
What disagreements caused the Berlin Wall to be built? | After WW2, what was left of Germany was divided into four zones, each zone administered by one of the allied powers: there was an American zone, a British zone, a French zone and a Soviet zone. Berlin, the capital and the largest city, was inside the Soviet zone, but it was itself divided into four sectors: American, B... |
Why do so many recipes not add salt to meat before it's cooked? | Whether or not you should *ever* salt your meat before cooking depends on the meat, the amount of prep time you want to give your meat, and what you are trying to accomplish. Not all meat needs to be salted, and depending on how you cook the meat, it might be counter intuitive. Salt removes some water from the meat and... |
if moon is visible during daytime, why does it affect tides during night? | The moon's gravity is what causes tides , regardless of when we can see it. The moon takes about 28 days to go around its orbit-- its position in its orbit dictates how visible it is to us. If it's closer to the sun, we can only see it as a shadow. If it's away from the sun, it's a full moon. Meanwhile, the Earth will ... |
Why does the USA use a "use it or lose it" funding system? | It's not really a system, it's how budget processes for all large organizations work. Let's say you have a factory and a marketing department. You give the factory a budget of $500, and the marketing department $200. You sit down to figure out the next year's budget and you notice that the factory only spent $400. That... |
Why do heat and cold kill things? | Imagine you had a small office, with some guy and a couple of assistants, all managing a bunch of paperwork. Usually, they're all very organized and manage to get all of the filing done more-or-less exactly right. One day, you pump them all full of tons of caffeine, and in the excitement and rush, they misfile everythi... |
How is it possible for us to imagine something we've never seen? What allows us to create images in our mind? | When you tell yourself to picture something, your brain has to actively pretend it knows what you're trying to imagine. It conflicts with what it's trying to picture and can only grab ideas or thoughts that we DO know. As for what allows us to visualize things in our mind, it's our brains lying to the rest of our body ... |
if i would launch a toy helicopter in a moving train will it crash into the back of the train or stay on the same place in the train? | Before launch, the helicopter is not moving in any direction RELATIVE TO THE TRAIN. The entire thing here is motion relative to the train. Once the helicopter is launched, if the results on solid ground would be that the helicopter would raise a slight bit and stay there, then the helicopter in the train would raise a ... |
Why does sound always sound so much better through headphones than speakers? | Headphones are really great at isolating you from the "not music" and also really good at not being affected by room variables, even with some cheaper sets. With speakers, you have many variables such as furnishings, speaker placement in relation to walls, distance from the speakers, what the speakers are placed on, th... |
How do chords work? | You play three notes at three different frequencies. The simpler the ratio of the frequencies, the more pleasant the chord sounds. An octave has a frequency ratio of 1:2. A fifth has a ratio of 2:3. A fourth has a ratio of 3:4. A major third has a ratio of 4:5. A major triad chord has a ratio of 4:5:6. A minor triad ch... |
on tv shows where some of the writers are also the actors like the office, do they get paid for each roll? | Yes. I don't know what more to say. Your contract will have payment structures for each role you are in. These payments can get quite complicated depending on a lot of specifics. Its actually really common to get paid for multiple roles on an entertainment property, especially when someone does something like being a p... |
What happend to the family name Hitler after WW2? | It pretty much vanished, as almost everyone who shared a name with the most unpopular person in the world changed there name. There's an interesting documentary called [Meet the Hitlers] about this. You should check it out; I saw it on Netflix a few months back. |
Why are there so many bricks and mortar travel agencies in immigrant neighborhoods? | If you want to fly from LA to Chicago, it's easy - you can just hop online, search for a plane ticket and leave. If you want to travel to a remote village in Vietnam, it's not so easy. There's a lot of paperwork involved in just getting permission to travel. You can't just hop online and find the schedules of some regi... |
why the human race would not last more than a month without insects. | I don't know exactly how true that is but they do directly and indirectly help us. Insects like bees help plants reproduce. Others are important somewhere in a food chain to feed something else that we eat. Others do things like aerate our soil. |
What percent of my current body/organic material is still here since my birth? | Here's an article which answers your question: "About the only pieces of the body that last a lifetime, on present evidence, seem to be the neurons of the cerebral cortex, the inner lens cells of the eye and perhaps the muscle cells of the heart. The inner lens cells form in the embryo and then lapse into such inertnes... |
How do first ladies pick their platforms? | it's not really a subject that has a definitive answer, the first lady generally comes out and says they are going to work on an issue, but the public doesn't know to what extent that decision is influenced by PR people etc personally i would bet that it's very likely that the topics are heavily influenced/vetted by PR... |
Why is it so hard to capture rain on camera? | Because water is translucent, rain is small, and the camera is not focused on it so it is this diffuse, small, translucent stuff that the camera doesn't have the definition to pick up. FYI: Akira Kurosawa, who primarily shot in black and white, usually dyed water with black dye in order to make it visible on screen. Wh... |
Economists of Reddit: Wouldn't Russia be better off with investing in their huge territories rather than fight over tiny areas in Ukraine/Georgia/Moldova? | It's less a case of economics and more a case of geopolitics. Russia views Ukraine as part of its buffer zone with Eastern Europe, and it cannot be seen to be allowing the west to push into its sphere of influence. It's money could well be spent elsewhere but it views the kind of threat posed by its satellite states gr... |
How do Customs/Immigration decide which page of your passport to stamp? | It differs by country . Some countries always stamp the next blank slot, some stamp randomly. Most of the time an exit stamp, if required, is usually marked next to the entry stamp. One thing I know is that some countries have their immigration officers look for stamps from other, less friendly, nations and will either... |
Why do restaurants place lemon slices in water? | Do you want to know the REAL reason?? I've worked in plenty of hotels and restaurants. The ONLY reason why any restaurant would spend money on countless lemons added to water is to improve the taste. Filtration systems are expensive, and without a filter most city water has a strong chlorine taste. Edit: Also, like oth... |
How did artwork like the Mona Lisa, The Last Supper or the Statue of David become so much more famous and well known than other lesser known impressive art? | I'm not familiar with the Last Supper and Statue of David's history, but I do know that the Mona Lisa was stolen right out of the Louvre, and later recovered, which contributed significantly to it's presence in the public's eye. |
How is the Politically-Correct definition of gender any different from personality, and how is it not sexist? | Actually to them and to many people gender is just what you identify as. So you could be the manliest bushwacker type of dude, have a dick longer than the wall of china and still identify as a girl. Many feminists actually like more feminine guys, and the guys who fit the description/stereotypes of a bro are often said... |
If an appointment, medical procedure or service has a very long waiting list, does that mean the waiting list will increase indefinitely as the demand will ways be greater than what is provided? | The answer here is a bit tricky. In most cases, no. There is no reason to believe that demand is going to keep increasing over time, and even if it were to, there's no reason to believe that we couldn't manage that. Managing demand is very common in the world and the most basic way to do so is just hiring more people. ... |
Do rainbows have a physical location? | No, rainbows do not have a physical location. They are going to be an arc that is centered around a straight line between you and the sun. When you move, the rainbow that you can see is also going to move. It's probably not accurate to describe the rainbow as moving because it's not a physical object with a location th... |
How does your body feed itself when you don't eat food for a smaller period of time? | Think of your body as a laptop. When it's plugged in you can use the electricity to run the laptop and it gets everything it needs from being plugged in. However, simultaneously it also charges up and saves some energy in the battery . This charging process can be reversed so that the laptop then can use that energy to... |
How are sleepwalkers able to make their way around the house without bumping into walls? | Their eyes are open. Sleep walking is not like you see in cartoons; unless you know someone is a sleep walker, you might interact with them at night without realizing they're actually asleep - I mean full conversations and the like. Sleep walking isn't eyes closed, snoring, walking around like a zombie. This is going t... |
The 'zero-tolerance policy' I keep reading of | Essentially, School created rules where they do not inquire into WHY and HOW FAR you broke a rule and punish you accordingly, but instead automatically punish you if you break a rule. i.e. No Drugs Allowed rules: people who bring an inhaler to school and people who bring hard heroine to school are punished exactly the ... |
Why does a warm environment make me sluggish? | Its your bodies way of keeping you cool in combination with sweating. When it is hot you are more likely to be less active as your body is warm enough and doesn't need to move around, thus you feel sluggish. It's basically your bodies way of trying to keep you from over heating, the less you do the easier it is to keep... |
Why does water in the shower go from mild to scolding hot when barely turning the knob? | The inside of most shower faucets looks like a nose. There's one "nostril" for hot water, and one "nostril" for cold water. The way that the faucet works is that there's a disc with a single hole in it in front of these two nostrils. When the faucet is off, the nostrils are blocked. As you turn the handle, the hole goe... |
How are we still "discovering" numbers? | A prime number is a number that is only divisible by itself and the number 1. Now since you're five, you don't know what division is. But let's assume that you understand division, and then I'll treat you like a five year old for the rest. How do you know if a number is prime? Well, you have to divide the number by eve... |
Why do almost all cups and mugs have inverted bottoms? | If they are made imperfectly then they would not sit flat, or teeter on every crumb.It is also so that they can glaze the bottom. Any glaze touching the surface of the rack in the kiln would bond to it, so you'll notice the ring on the bottom is not glazed.You also see this in wine and champagne bottles that have a inw... |
Why do we like unhealthy food? | These foods are unhealthy in excess. In small quantities, however, they are very desirable because they have lots of calories. That is a good quality when you are an animal who never knows when its next meal is going to appear, and who might need to go without food for short periods of time. As such, human evolved to f... |
Why do we use the WASD keys for movement in games? | Actually, arrow keys were commonly used before the mouse era. Think Wolfenstein 3D, Rise of the Triad, even DooM. Since you couldn't look up or down in these games, it made sense to use the arrows to navigate in 2 dimensions with your right hand, and other actions would be done with the left hand . However, when the mo... |
Why can you grow a plant hydroponically but if you take the same plant in dirt you can over water it and kill it? | Plants breathe through their roots. If the soil is wet and the water has no dissolved oxygen in it then the plant will suffocate. Hydroponic water has air pumped into it through a bubler system to keep its dissolved oxygen levels up so the plants can breathe. |
Why Curiosity's "hovering platform that lowers the rover on a cable, then flies off" landing system was better than previous probe landing ideas. | There were several problems they needed to solve. The obvious one is a soft-landing. As pointed out by AnteChronos, MSL is really very heavy compared to any other rover. That means that either crash-landing inside airbags or simply parachuting wouldn't work. Remember that the Martian atmosphere is very thin, and provid... |
how does Soundhound/Shazam work? | Funny thing is, that's actually a hot area of audio DSP research these days. Having something that can recognize what a sound is and whether or not someone will enjoy it is worth a lot of money. The principle isn't that complicated. What the program in question does is break down an incoming signal into components. The... |
They say if your stranded at sea not to drink the salt water because it will kill you faster, however dehydrated patients are given saline drips. Why? | On average, seawater in the world's oceans has a salinity of about 3.5%. Sea water also has all sorts of other stuff in it. Normal saline is the commonly used phrase for a solution of 0.90%. Saline contains water and salt. |
How is it that ants seem to see equally well underground in the pitch black, and above ground in direct sunlight? | Ants don't rely on eyesight nearly as much as we do. Their use of trail pheromones and appendages like feelers give them other sensory inputs to know what's around them and where to go. |
Why do doctors always have messy handwriting? | They can't be bothered. Working non stop hours, people dying around you. Gotta get in and out and on to the next one. |
Why does a simple atom like hydrogen have multiple absorption lines on spectroscopy | The hydrogen atom has infinitely many bound energy levels, and you can have transitions between any two of them, as long as no conservation laws are violated. |
How are charities able to feed multiple children with small individual donations of $7/day when here (USA) it would be enough for basically 1 maybe 2 children. | $7 a day can feed multiple people quite easily here in the US, too. Go buy a giant bag of rice, and a few bags of dried beans. That can feed a single person for about $1 - $2 per day. Of course, you have money, and you're not starving, so you're not satisfied with just eating rice and beans. |
if we put huge magnifying glasses on solar panels would we get more energy? | If the magnifying glass was larger than the solar panel and designed correctly, then yes you could. What a magnifying glass does it take the energy over a large area and focuses it to a smaller area. If you have a 1 ft square solar panel, it would harvest more energery if you put a 10 ft square magnifying glass over it... |
How can a company like Netflix charge less than $10/month to stream you literally thousands of shows, yet cable companies charge $50 /month and we still have to watch commercials? | Part of it is what other people are saying about how Netflix doesn't maintain the cabling etc and that is handled by the internet company. What doesn't seem to be mentioned yet though is that Netflix gets most of its content after it has already been milked for as much money as possible. Judging from my experience anyw... |
How do modern vehicles prevent wireless keys from being locked inside? | As a person that’s worked at a Car rental place. They really don’t, most cars will give you a message in the dash about keys inside but that’s about it. I’ve had to deal with locked cars that are keyless and having to unlock them with tools. Hell, you could even start your car up go back inside and leave the keys insid... |
Why do cell phone sounds and screens always look and sound different than the real things in movies? | Usually because there's some level of copyright over the interface and appearance of the phone screen, and they don't feel like paying for the license to use it. They likely wouldn't have to go through much to make up something different and certainly wouldn't need a functional phone operating system, just a couple ass... |
Why do things (mainly sweet things) taste like shit after brushing my teeth? | SLS, Sodium Laurel Sulfate. It causes things to foam, whether toothpaste, shampoo or soap. It also does something to the fatty coating on your tongue that dulls the sweet taste buds while making the bitter more sensitive. Full Disclosure: I learned this from a Cracked article, but you better believe I look for a chance... |
Stupidity. What makes someone (objectively) stupid and how does someone becomes stupid? | Genetics, epigenetics, nutrition, and education. People who were born with a poor maximum aptitude for intelligence are often born into families with low socioeconomic status, and so have poorer nutrition and poorer access to quality education, which further compounds into fewer educational opportunities, and often int... |
what exactly happens when an officer gives me a warning instead of a ticket? | > I was just curious as to what happens when he goes to his car and looks up my information? He is checking to see if the registration is still current on your car, checking your drivers license to ensure it is still valid, and checking to see if there are any warrants out for your arrest. > Does it get saved that he l... |
If viruses aren't alive how are they able to do what they do? | They hijack living cells to do it for them. Viruses are pieces of DNA in a protein shell. A cell absorbs it , at which point the viral DNA is released, which tricks the cell into making more viruses. Eventually, the host cell makes too many, at which point it explodes, releasing new viruses. A computer virus is a good ... |
How does the DCCD actually work on the Subaru STi? | Mech Eng and Subaru WRX STI owner here. Feel free to ask me more detailed questions if you'd like. Multi-mode DCCD explained by [Subaru's Website:] > The Driver’s Control Centre Differential allows the centre differential locking of the WRX STI to be dialed in and adjust its handling. It adjusts both an electromagnetic... |
How are tree representations used as a data structure? | Tree structures are all over the dang place. You're looking at one right now! The elements on any web page are stored in your browser's memory in a tree structure called the Document Object Model . The filesystem on your disk has one obvious tree structure and usually a few internal ones that keep track of which blocks... |
Why does Doha, Qatar have such a massive skyline when it's population is only 2 million. Who is benefiting from all those buildings? | In terms of area covered, Doha is relatively average for its population. You can go to google maps and compare the city to others of comparable size, and see it's not that huge compared to others. As for the actual sky scrapers, Doha is the economic hub of a country undergoing an economic boom. Most of Qatar's money go... |
Why do big TV stations allow their shows on Netflix when they own it's competitor in Hulu? | The TV stations don't own the shows they broadcast, in most cases. They probably own the local news and programming like that. Big budget shows are owned by the company that produces them. The Network, or the local station, negotiate a contract giving them rights to broadcast the show, subject to some restrictions. Not... |
Why does wind or moving air in general feel cooler than the surrounding air? | Humans produce heat so any wind that passes us removes some of our own radiated heat. Like blowing on hot food. Even though the wind may be hotter it will still feel cooler when it blows by because instead of our heat adding to the heat from the air at least now our radiated heat is being pulled away. |
How much will it hurt my job application if I don't sign some consent forms? | Some employers may consider your application incomplete and discard it. If they decide that those consent forms and background checks are necessary to be considered for the position you'll probably be dropped from the running. Whether or not that is legal depends on where this is all happening. |
Why does it take so long for movies to be released on DVD/Blu Ray after their theatrical run? | It's economics. I'll try to keep it very simple. When a movie comes out, it shares the ticket price money with every theater it is in. That percentage changes every week, but that's really another topic entirely. The point is, every week the movie is in theaters, it's bringing in money. So you want to stay in theaters ... |
Why is some produce like avocados and limes sold by the count instead of by weight? | They are very similar sized. This takes the guesswork out of the purchase as the customer knows their total commitment before they have it weighed. That encourages more purchases. Items that have more of a variance in weight would be scrounged though for the heavy ones. Its a good idea to discourage people scrounging, ... |
Why do so many people hate the word Moist? | I think it's learned. Other people say it sounds gross, and in turn you start to think it's gross", 'Because moist suggests something is wet and hot. In wet and hot environments, bacteria thrive, causing disease to settle in. Things like mold, open wounds, etc. are all things that come to mindI thought Lily was the onl... |
In what ways have the "Fiscal Cliff" outcomes affected the US over the last 6 months? | They have taken the attention of the country's legislature away from important issues, preventing real action in the fields where it is really required. The 'Fiscal Cliff', like debt ceilings, are political constructs created soley for party-political purposes. The media likes to play along. |
What makes a sailboat faster than another? | What makes a sail boat faster? Well how aerodynamic the hull is to reduce drag, how much wind the sail can catch from their shape and size and the weight of the boat itself. What makes the Black Pearl the fastest ship in the Caribbean is that the writers say it is the fastest somehow and therefor it is. Probably magic,... |
Why does any number raised to the 0 power equal 1? | Let's revise a few exponential rules. x^a * x^b = x^ Inversly: x^a / x^b = x^ So; that means that: x^a / x^a = x^ = x^0 = 1 is 1). . Eli5:any number to the power of any positive integer N represents the outcome if you multiply the number to 1 N times. If you never multiply the number to 1 all you have left is 1.By defi... |
how does glass break. | Maybe [Smarter Every Day] can help. That's a special case of glass in a particular shape/configuration/whatever. But we can apply what we learn from that to other instances of glass breaking. We can also look at [more Smarter Every Day] about spaghetti.

How do microphones on my computer or phone ignore their own speakers while hearing my voice? | Sound works like numbers. If I give you 3 apples and you give me 5 apples back, I can just subtract 3 from 5 to know that you added 2 apples to the pile. If I play a sound while you record a sound, I can just subtract what I played from what you recorded to find out what you said. |
What Game Theory really is | Game theory is kinda hard to explain without applying it to a situation. So I'll try an example and see what you get out of it. When tobacco industries were banned from certain advertising, all competing companies had a rise in overall profits, money saved from not advertising. By eliminating a method of competition, a... |
Why does stress make your hair turn gray? | That is currently purely speculation.There exists no proven cause and effect relationship between stress and gray hair, tell me if you find a source from anyone that says so. [Here's a source supporting the idea that most of these other answers are mere speculation.] **EDIT: From a reply [here], it turns out that there... |
Why do those “Congratulations! You’ve won a $5,0000 gift card” redirect sites only appear on my mobile browser and not my desktop? What exactly are they? | They are primarily malware, sometimes just a scam. Your desktop browser is probably just better at blocking that stuff or you have adblock. |
Who determines the rating of a hotel ? and based on what ? | At least in Europe, star ratings are mostly based on what services/facilities/'minimum standards\' they provide. It's not an indicator of quality, but what they have to offer "on paper". Airco, Telecommunications/Internet, bathtub , Parking, 24h reception, minibar, roomservice etc could all be super crappy, but they wi... |
How can Japan have such a weak economy when its people work so hard? | Working hard is different from producing value.You could be working very hard at digging up holes with a shovel, filling it back up, and repeat, 22h a day, and be very good at it, that would be really hard work. And you would have accomplished nothing. A society that works harder than another accomplishes nothing more.... |

Each state holds an election in the early part of a presidential year that any registered voter can participate in, with some caveats.

How there are traces of stars in humans | After the big bang, the only matter that existed was hydrogen, with a small amount of helium and lithium. There were no other atoms. No carbon, no oxygen, no gold or silver or copper, no potassium or sodium, etc. When the hydrogen condensed into stars, it began fusing into heavier elements. And when those stars went su... |
Why do people have a hard time judging the quality of their own work, but an easier time judging others? | Someone looking at their own work doesn't see the entire work as an observer would, they see the entire process; they 've focused on certain parts far longer than others, gone to great detail. When they see it, they no longer can easily compare to the work of others - since they know more than the product, they know th... |
What drives a hamster to run on a spinning wheel? | Since running wheels aren't a naturally occurring phenomenon for rodents, they probably see the wheel as a stimulating form of play. Scientists recently discovered that un-caged wild rodents voluntarily ran on excerise wheels when given the chance! _URL_0_ |
