Why do most modern American homes have both a kitchen table and a dining room table? | Sometimes, if the furniture is particularly expensive or formal, the reason is to keep it show-ready for when you have guests over. That's increasingly unusual, though. Mostly it's because the kitchen is both closer than the dining room to serve food to and also is large enough to fit a table.The dining room table is f... |
If the apples you buy at the store were picked an average of 14 months ago, why does fruit spoil so fast after you buy it? | Former produce manager here. Apples are very slow breathers so they have a very long shelf life. They are also stored at an optimal location in an optimal temperature for the duration of time it's in storage. When they put the apples out at the store it's being handled at a minimum of 4 times from that point. That's no... |
what would it be like if humans could see the full visible spectrum of light? | You'd see tracers and trails of moving objects with heat. You'd see auras around animals and electronics that are on. You'd see more patterns in plants and animals. A crow would have amazing colours in it's feathers instead of blackness. I'm sure your smell and touch would change to compensate for what you feel and see... |
Why are boy choirs more common than girl choirs? | Tradition is the biggest part, starting back when women weren't allowed to participate in church. If the composer wanted high notes he needed boys . This also created a demand for children's choirs to find and train the talented ones. Some of those groups lasted for many years until it became a tradition. |
If I had a closed room with a light bulb, and turned that light bulb on, would the room indefinitely fill up with photons? | It would not, but it would get warmer. Basically, in the light bulb there is a reaction where one of the products is a photon, that photon will fly across the room till it meets an object, then certain frequencies will be absorbed and the others reflected . Another way to look at this is that photons aren't really part... |
How does owning a domain, hosting using BlueHost, using Wordpress as platform, and Studio press for theme all work together? | 1) There is a record in the WHOIS database saying that you control a particular domain name. This was purchased through Weebly from an organization called ICANN, who controls the global Domain Name System. 2) By adjusting records in the Domain Name System, you tell any request to _URL_0_ to redirect to BlueHost's serve... |
How do the speakers and mics of waterproof smartphones work (like the IP67 iPhone 7)? | Usually there is a barrier, a thin sheet of Mylar. That's why there isn't much depth rating, serious pressure differential would fail the membrane. A little extra amplification, adjusted to offset the dampening of the protective film, cover up the existence of the barrier. |
Why am I able to hold my finger over a lighters flame without being burned right away? | Well, in the picture included, the trick is to get most of your finger below the flame. Due to the pressure of the gas escaping the lighter, there is a small gap between the nozzle, and the actual flame. Next to that gap is a low heat flame, due to the lack of oxygen compared to fuel. Find the right spot, and don't hol... |
I am new here and don't know if this has been asked already but ELI5: why America funds so many countries with different things when their own country is going through so much trouble? | The US gives a very small percentage of GDP as aid. . The US government gives about 50 billion dollars a year in various forms of aid and the private sector give about 70 billion - most of that is foreigners who moved to the US and are sending money home. That is, out of total US federal government spending of 3700 bil... |
why is Guantanamo bay in Cuba and not in the USA? | By removing it from US soil, the prisoners there aren't subject to US law and that includes the laws regarding unlawful detention. If they were on US soil the government would actually have to hold a trial and prove that they've done something wrong. Having it on foreign soil means that the government is subject to int... |
Why is there a jury? | The judge is there to decide issues of law and the jury to decide issues of fact. The judge has to be trained in matters of law, but the rationale is that '12 good men and true' are in just as good position to arbitrate issues of fact - i.e. did he stab her? did she steal the money? - with the judge guiding on technica... |
What is taken as a metaphor in Christianity and what is thought to be the Truth? | That depends *entirely* on the sect. Different sects claim different bits are true or just stories. AND it changes over time. The Catholic Church used to imprison and execute people for suggesting parts of the Bible weren't literal truth. Today, their official dogma is that things like The Flood and a literal seven day... |
- Why does 9 * 1/9 not equal 1? | I used to break my head over this as well, until someone asked me this:what would you add to 0.9999 to get to 1? There is nothing you can add, because it keeps repeating. Thus you'll add 0.000 0.9999 and 1 are the same. |
Why was it so easy to rally support to stop Kony but not to stop the war in Afghanistan? | Correct me if i'm wrong, but weren't the taliban actually involved in 9/11? That's probably why it's easier to get support for Kony, but harder to stop the war in afghanistan because we actually should have put all our resources into afghanistan and the people who attacked the US instead of Iraq.Because America is actu... |
How does saving pop tabs off of soda cans help a cause? | I believe when someone collects a bunch and turns them into the Ronald Macdonald house, they take the gesture into account and money is donated because someone took the time to collect and turn in. I don't believe they get the money from recycleing because that would be ineffective. |
How do they show events that have not happened yet on T.V.? (Ads for the opening ceremonies in Sochi) | It's footage from past Olympics, or footage taken from dress rehearsals, etc.Sometimes they show archived footage from previous events. Sometimes they travel through time. |
why do animals especially dogs and cats seem to have the same physical characteristics? | Everything has a common ancestor through evolution. Generally, animals that look alike share a more recent common ancestor so their looks haven't diverged as much. In general, all people look similar compared to how we look to other animals. But, when you look country by country you see differences in common features. ... |
How does the drinking game from Shanghai Noon (the movie) work. | Had this game explained to me last night, apparently it is a simple 'if you get the words/symbols wrong you drink' The first part: páng xiè yī ya zhǎo/zhuǎ bā ge liǎng tóu jiān jiān zhè me dà ge yǎn yì jǐ a bó yì suō pá a pá a guò shā hé From here it is a repeated number sequence with rock paper scissors hand gestures ... |
In programs like VLC, why does the screen freeze or show blocks when going to a random position in a movie? | Due to the way video compression works.To make files smaller only the changing parts of the image are stored for some period of time, after a certain number of frames the full image is stored. So, when you jump it's very likely you arrive at a point where the player doesn't have the whole image so it just displays what... |
out of everyone who uses reddit, how is every post so averaged out in upvotes and downvotes that its rare to see anything above 4000. How come there aren't more landslide upvoted posts? | This gets asked about a lot. Reddit fuzzes the number. The way it's done is hidden so that people can't abuse it. |
during hyperinflation, if someone hoards an obscene amount of money, say $1,000,000 and that has little value during hyperinflation, what happens to that amount once the economy stabilizes? | Let's say you lived in Peru in 1975. You have 10,000,000,000 soles. They're worth about 270,000,000 USD, so you're quite wealthy. Over the next ten years, the value of those soles declines until it's replaced by the inti at a rate of 1000:1. Now you have 10,000,000 inti. The inflation continues until in 1991 the inti i... |
Why can't homeless elderly claim social security and medicare? | I used to work with a lot of people like this. There's a lot more involved with both processes than it seems. In order to qualify for Social Security Disability Income , you need to be deemed disabled by a doctor. Usually many homeless individuals don't have insurance and can't afford the costs of seeing a doctor. Even... |
Why does going outside to get some "fresh air" genuinely seem to help with headaches/feeling ill? | Poor indoor climate has a huge effect so actually getting fresh air helps. Stepping out in nature opposed to walking around a really poluted place like Times Square also helps as the air is actually 'fresh'. Also oxygen. Oxygens helps relieve headaches. If you suffer from bad headaches then you can actually go to the E... |
How do doctors perform 20+ hour surgeries? Don't they get mentally and physically exhausted? | Yes, if it's going to take that long they work in shifts. Even during a more mundane procedure, the surgeon will often have a resident come in to do certain parts. |
Can people really die instantly if someone snapped their neck like you see in the movies, or would it likely take a few minutes? | so, just to split hairs, would it be more accurate to say that it's likely asphyxiation that kills you and not necessarily the breaking of the neck. |
Recently in class I heard a shoe squeaking in the hallway at the same time that someone was writing on the chalkboard... | My cringe sound is when someone pulls apart Velcro slowly. I'm not sure why, but it's bothered me since I was a wee child. Nails on a chalkboard don't bother me at all.If you are willing to dive a bit deeper, the podcast Twenty Thousand Hertz just had an episode about why we find certain sounds annoying _URL_2_I'm taki... |
Why must phones be turned off at gasoline stations? | Gas stations that used to have no cell phone warnings at the pump, that I frequent, have removed them. It was essentially a hoax. Its virtually impossible for a spark from your phone to ignite gas vapors in the air. _URL_1_ Mythbusters tried, really really hard to make it happen, and couldn't. _URL_2URL_0_", 'People on... |
Where did the stereotype of rural, southern people being inbred/kissing cousins come from? (West Virginia, Alabama, etc.) | Cousin marriage isn't all that uncommon historically, even in the more civilized regions of the world. The inbred hillbilly stereotype comes from the fact that Appalachian communities are highly isolated, with outside blood rarely ever entering and insiders rarely leaving. Over time, intermarriage breaks down what fami... |
Why do my gums bleed when I floss? | If you brush and floss regularly, you should not see bleeding. My dentist also recommends interdental brushpicks, so I've been using those as well. If you are brushing and flossing regularly and are still having bleeding, see your dentist as soon as you can - there may be some other issue. |
I'm addicted to cigarettes, but only when I've been drinking? | 3 basic reasons. 1. If you associate the two things with each other, you will want to do it. If you are used to smoking while drinking, it just feels natural. 2. Alcohol lowers your inhibitions. Maybe its talking to the ugly guy/girl at the bar .maybe its smoking. Things you wouldn't normally do become normal when drun... |
How do you come to a full stop in a stick shift vehicle? | You just put the car in neutral and brake like normal. The car will only stall if it's in gear and you release the clutch. If it's not in gear nothing will happen when you release it.The wear you put on a vehicle by holding the clutch down completely is negligible. If it is a long stop, put it in neutral, otherwise jus... |
Why can we get electricity from wind on earth, but planes do not have small wind turbines to lower gas and electric costs? | Planes already convert chemical energy into kinetic energy, which means some goes to waste. All the kinetic energy is generated to make up for that lost in air resistance. Putting a turbine just creates extra resistance and converts that kinetic back into electricity, which is already generated efficiently in the plane... |
Why they shut down Megaupload and why everyone is extremely happy that "Mega" is now on? | Megaupload became a major source of piracy. The USA thought it had enough of a reason to arrest Kim Dotcom and shut down the site. The problem is, they really didn't. Other services also had piracy, but Megaupload was targeted for whatever reasons. Kim's rights were very much violated during this process. The FBI plann... |
If we all know people make money from ad clicks, why haven't all web users taken an approach to clicking a few extra ads just so there's more payouts for all? | When internet advertising was new, it was OK to trick, beg or offer incentive to users to click on ads. Advertisers soon realized that all these clicks weren't converting into sales. They wanted quality clicks . When rates went down, many webmasters piled on more ads to try compensate. This causes more users to downloa... |
Why we tip based on price, not amount / difficulty of service provided? | Real estate agents are even worse. There's little different that an agent does for a $600k house that he doesn't do for a $300k house. But you pay him twice as much for the $600k house. |
Why can't I fall asleep on my back, but I wake up laying on my back sometimes? | I too have the same problem. Not long ago I found out that when I was a baby my mother would lay me down on my stomach when putting me to sleep. She was told that babies are more likely to choke on spit-up and whatever weird liquids are going on in a babies face . I've always wondered if the reason I couldn't sleep on ... |
Math being truly universal. | Tldr; The physics of the universe is constant so another species developing similarly to us will understand it. The formulas are all uniform no matter the species, it's the symbols that change. |
Why can does bark what seems like forever but people can only scream for a hour or two? | Probably the dog has time to breathe in between barks. Screaming without stopping doesn't allow you to catch your breath. Also, I would like to see somebody who can scream for two hours :)", 'Something to do with their genetically stronger vocal chords maybe?Dogs have superior vocal cords, so much so that it is impossi... |
Why does a flashlight have a finite area of effectiveness and not go on forever? | The total energy in a light beam stays the same as it travels. . Since the light beam energy is spreading out over a wider and wider area as it travels, the brightness of the light at each point must get weaker by a corresponding amount. It's a bit like spreading one spoonful of butter over a small piece of bread versu... |
How does a physical piece of memory "store" digital ones and zeros and why are hard drives limited by size? | Standard hard drives store data as tiny bits of magnetism on a metal platter. [This is a good video] that covers how they operate. You can't pack infinite amounts of information into a space because there are always limit to the technology used to store that information. In the case of standard hard drives those limits... |
Why are we taught to write our lowercase A's as "ɑ" but on the keyboard and the computer all the lowercase A's are "a"? | Most serif fonts actually write out a and g the handwriting way in italics. So there are two ways of typesetting a and g, and we're just taught to write out one of them. But I can't demonstrate in this post because, at least for me, Reddit has a sans serif font so *doing this doesn't work at all*. Edit: in [this exampl... |
Why does cell phone coverage decrease when a lot of people are in the same area? | I've worked at many many large events and a friend of mine is also a cell engineer with a major carrier. The sheer number of phones overwhelms the cell sites. Even when the company knows there will be a large gathering and deploys temporary cell sites to help, it's still way too many phones trying to connect to the sit... |
How do we sweat, and what keeps us from leaking blood? | Skin isn't watertight. You can absorb lotion through your skin, right? Sweat leaks out through pores, not just anywhere in the skin. These glands take water out of the bloodstream and excrete them onto the skin. Blood is not a single substance. It's a mixture of water, some vitamins, platelets, and cells. Your blood ve... |
How did ancient people kill and harvest whales? | Whales need to surface for air, so you don't really have to worry about how deep they swim, you hunt them when they come up. They float so once they're dead they're not going anywhere. Some whales get injured by nature and if they're too injured to swim well, they'll be near the surface already. The best way really to ... |
Is a two sword fighting style actually practical? Or is it just something Hollywood and video games show to look cool? | There's a famous Japanese swordsman and philosopher, Miyamoto Musashi , who wrote the Book of Five Rings. He fought with two swords , a katana and wakizashi , and actually founded the particular style and discipline of that Japanese swordsmanship. So it is at least in part not Hollywood mysticism as Musashi was a succe... |
How is it legal for the NSA to track data from outside the US? | Think of it this way, if it's not legal, then what law is being broken? More particularly, who would have the jurisdiction to make a law governing the relationship between the NSA and someone in, for example, Spain? The answer is there is no law and no body with that law making power. The U.S. constitution affords cert... |
How did google go from a search engine to one of the biggest companies in the world? | Google developed the worlds best search engine ever. It turns out that a search engine is also good for other things like finding customers for targeted ads. Those two things went hand in hand. Google also tried many new and different things like street view, maps, and many other things. If it worked, they stuck with i... |
How did humans survive in places where it snows before the heater or the fireplace existed? How would have previous humans lived in such freezing weather? | Are you sure that they didn't have mastery of fire before they moved into cold climates? Remember that people started out in Africa, where it is warm. They probably had control of fire long before they moved into the Northern latitudes. |
Why do we measure speed by the hour instead of minutes? | I think if you wanted to use this approach you'd actually need minutes per km to avoid doing lots of maths. Your suggestion is only easier because of the numbers you made up. If I drive at 60km/h and my friend lives 60km away it's easier to use km/h! It would be a trivial exercise to add markers in this metric to a spe... |
Because I watched Revenge, why does Netflix believe I would also like "Clifford the Big Red Dog"? | I think the suggestions are based on the ratings people give than just similarities. This should result in suggesting being mostly similar content, but not necessarily. Maybe there's something about Clifford that just resonates with people like you!", 'The long and the short of it is the Netflix algorithms are terribly... |
How is audio created with only 1s and 0s? | that loud", and "so-and-so loud" are just numbers. Any number can be described with just 1's and 0's - for example, "When I say 0, I mean 0; when I say 1, I mean 1; when I say 10, I mean 2; when I say 11, I mean 3; when I say 100, I mean 4; when I say 101, I mean 5."The ones and zeroes are used to encode numbers that r... |
I'm a lurker - please explain reddit karma | You ain't cool if you don't got no karma, man. Nah its meaningless in the long run. Just keeps track of what makes the front page and what doesn't. |
Why is mordern sci-fi so predominantly dystopian? | Even if the setting is futuristic, SciFi usually isn't really about the future -- it's about the present. During the 50's and 60's, invading aliens were stand-ins for communism. In the 1970s, movies like Logan's Run and Soylent Green channeled fears about overpopulation. In the 80's, cyberpunk fiction and movies like A... |
Why aren't blimps and zeppelins more popular? | Now blimps are just for show and advertising, zeppelins in WW2 and before I believe, were used to pinpoint the location of the enemy from a safe distance, since no one dared to cross into no man's land |
All the "Face of Atheism" posts | It's one of those days when atheism goes minor retard and you have to unsubscribe for a day or two.Miley Cyrus posted a picture on Twitter of theoretical physicist Lawrence Krauss along with a quote by him that says something along the lines of: "the atoms in your body are from the explosion of stars, so forget about J... |
If a nuclear missile is shot down from the sky, say several miles above a large city, what would happen to the city below? | Others have sufficiently answered your question. I'd like to give you some supplemental information. Whole missiles do not travel to their targets in this day and age. Missiles travel into a parabolic flight path into low orbit towards their targets, then detach. Each warhead is contained inside what's called a reentry... |
Why does oxygen become lesser at higher altitudes? | Because everything becomes lesser at higher altitudes. This is because it *can*, because a bunch of other air isn't sitting on it and mashing it down. |
What are the actual rules/laws with dump trucks that have the sticker "Not responsible for broken windshields"? | Am I alone in noticing how rare it is to be able to actually see a readable license plate on these things? Pretty sure that's to make reporting your broken windshield harder. |
Why can't cashiers in America sit down? | I wonder if the only reason Americans associate sitting cashiers with laziness is that they are used to having them stand. As someone who has dealt with sitting cashiers his entire life, the idea of considering them lazy seems absolutely ludicrous to me. Their job isn't to stand around, but to handle the cash register.... |
Why did people associate being left-handed with the devil? | I could be wrong, but the I believe in one of the older versions of the bible it stated that Eve grabbed the apple with her left hand, so it was associated with original sin, at least in the western cultures. A friend of mine works with Gnostic texts a lot and showed me something about that once, but I do not know if t... |
If I hold a green light and I go into a dark I would see everything in that room not only green things(i.e Things that reflect green color)? | Objects that reflect no green at all will appear dark black. Many objects have a blend of colors, so even though there don't look green, they still reflect *some* green light -- for example white and gray objects, and many yellow and blue and brown objects.The walls of the room are probably white, so they reflect green... |
Why is Cuba not more modernized despite the US embargo? Did no other countries choose to invest and trade with Cuba? | I think it's mostly Cuban state policy. There is some foreign investment. For example, there are a smattering of European owned/partially owned hotels. However, the Cuban government regulates the economy and foreign investment pretty aggressively. |
Sometimes I open my mouth and spit shoots out much in the same way venom shoots out of the mouth of a snake. | If you press the bottom of your tongue against the roof of your mouth a certain way and move your lips out of the way, you can do it on purpose. I can fire it about 4-5 feet. It helps to scratch your tongue against your teeth first to produce excess saliva. It's called [gleeking.] [Here is a video showing someone doing... |
technology is moving at rapid pace so why is the combustion engine stuck in place? | First things first, IC technology has advanced by leaps and bounds in the past few years. Direct injection, variable timing, sensors and computers, and other refinements/innovations means modern engines are far more efficient and powerful than predecessors. To put it in context, a 1996 Corvette with a 5.7L v-8 made 300... |
why does comcast Internet slow down despite offering 20+mbps | because it's a shared medium. and your internet speed doesn't depend solely on your isp. it depends on the entire connection from wherever you're trying to access.To be a little more clear, you share the "pipe" with your neighbors. |
Why do we all laugh differently? | In the 90s all my friends and I gradually started laughing like Beavis and Butthead. I don't remember anyone saying let's laugh this way, it just happened. Thank god we all laugh normal again. huh huh hmm huh huh.Science Friday did a show about this. Falling asleep someone should look it upI can recognize a friend simp... |
Why are dog years shorter than human years? | Because they mature faster and die younger than us. It's a way of saying that a 1-year-old dog is at a similar stage of life as a 7 year old human. It's an accurate enough *guideline*. or maybe we are looking at this backwards. Could it be that human years are prorated to reflect the much shorter life span of dogs? |
If Rio de Janeiro is so screwed up with crime, corruption and waste and yet is still having the olympics anyway, could the olympians just not participate? | They could, they won't. Olypians train for decades for this. It's their *life*, it's everything they work for. Asking them to bow out is a BIG ask. Especially because it's a prisoner's dilemmna. What happens if US backs out and Britain backs out and no one else does. Then Russia and China run the medals. They get to pr... |
Why can't Elon Musk solve the reusable rocket problem by using a coil gun and single stage rocket? | you need to achieve 11.2 kilometers a second. V=A*T _URL_1_ > The body has to muster double that at 2g, triple that at 3g, and so on until they hit around 4 or 5 G's, at which point most folks will pass out due to oxygen starvation because all the blood stays in their feet. _URL_0_ > Astronauts normally experience a ma... |
why aren't we investing in engines that run on hydrogen? | We are. The technological problems are just so large that there's not much interest in really doubling down on the research because the payout is uncertain and not a very quick one. The infrastructure is a large problem, for example. How do you transport and store hydrogen? Hydrogen is a gas in its raw form which needs... |
How much power does an executive order from the POTUS hold? | The US President can declare an executive order to achieve any one of these four things: 1. To enforce an article of the constitution, which must be cited as part of that order. For example, the Emancipation Proclamation was cited as protecting the American principle that all men are created equal, and that no one shou... |
Is this as worrying as it sounds? "Resistance to last-resort antibiotic has now spread across globe" | I'm no expert, but I read that R & D into new antibiotics is limited because even if they develop a new one, it ends up being a last resort antibiotic which will be given only in some cases, leading to less sales and less profits. Source: _URL_0_ |
How do Sin, Cos and Tan work? Where are they derived from? | Are you asking what's the purpose of trig? Like, we could have a whole bunch of math devoted to studying the ratios between lengths of other lines, but we dont. The reason we measure the angles in circles, is because it relates to lots of things around us, including the orbit of planets, how ropes and springs and elect... |
Why Does beer taste different when I get it at a restaurant, from when I buy it from a store? | When it comes to beer on tap a lot is placebo as stated by another poster and yes, the beer itself is often fresher as kegs get used, don't sit on supermarket shelves for months. BUT The line plays a huge part too. By this i mean the piping between the beer keg and the pump. In an ideal world these lines should be clea... |
Why is widespread use of antibiotics breeding antibiotic-resistant bacteria, but widespread use of refrigerators isn't breeding cold-resistant bacteria? | I would like to add that there ARE cold-resistant bacteria. However, the ones that infect us aren't likely to be cold-resistant because they need to be able to infect us. We are warm. |
Why does water conservation not address humans consuming water rather than running faucets or showers? | Conservation is all about using resources in the most efficient way, prioritizing the most important uses so that the resource isn't taken away by lower-priority uses. Water consumption by humans is at the very, very, very top of the priority list for water uses. Everything else is less important. |
What happens if a baby is born in an international flight going over international waters? What citizenship would the baby get? | It depends. Likely it would take the nationality of its parents. If it couldn't and would otherwise be stateless, it would take the nationality of the country the airplane is registered to. That is also true for cruise ships.The baby now belongs to the world. For real though, women in their third trimester are not allo... |
My neighbor's rooster starts cock-a-doodling at 4am every morning. Why do roosters do this, and always right before sunrise? | There's a crow down my flat that make some f noise every morning and shut up later, I'd like to know too what its problem. Or maybe a way to get rid of it in a civilised way.I see that other commenters have already explained why birds will sing in the morning and the evening. To answer question as to why roosters sing ... |
Why, after flipping a coin to decide something, do we then flip the coin back over again onto the back of our hand before revealing? | Mostly for convenience at the small cost of knowing that we add 1 half flip to every toss. Really, each toss of a fair coin will come up heads 50% of the time, and tails 50% of the time, but in random intervals. So as long as our method of flipping is *consistent* across each flip, what we do before the reveal of the f... |
Would a refrigerator act like a heater if placed outside in subzero temperatures? | Any sort of heat exchange machine always outputs a net surplus of heat because they consume energy to operate. A refrigerator operated in any environment will output heat. Refrigerators are not usually designed to work in places such as Antarctica because all the need is that the heat exchange coils on the outside of t... |
Why is the night sky so static? When people look through telescopes do they ever see things moving in real time, like a spinning galaxy for instance? | Galaxies take hundreds of billions of years to make a single rotation. That sort of length of time is about the same whether it's the Milky Way , the Andromeda Galaxy , or a distant galaxy viewed through our most powerful telescopes. It still takes 200 billion years to turn once, so unless you can stare it for millions... |
why sometimes after swallowing larger pills it feels like the pill is still in your throat. | ELI5:It was likely stuck in a side pocket in your food tube. Stuff in this area doesn't block your breathing. There are spaces near your epiglottis called the piriform recesses. They tend to catch small things such as pills, peanuts, and parts of chip crisps. Drink lots of fluids after taking a pill because if it slowl... |
When going to remove software can I just delete all of the files or do I have to do the uninstall process? (PC not Mac) | You could delete all the files and manually delete all the registry entries, but it's hard to be sure you got them all.No. Windows programs strew files all over your computer along with registry entries. You have to use the uninstaller to get at least a semblance of a clean removal.You can't even find all the files in ... |
If Oscar Pistorius was found not guilty of Murder, the crime he was being charge with, how was he found guilty of Culpable Murder, a completely different crime? | he was found guilty of something that is similar to manslaughter. This means that through his negligence he caused the death of someone through what might be called an 'accident' but he did not intend to kill them. It also means that he could have prevented the death if only he didn't act in the stupid way he did. |
How did humans keep their teeth from rotting out before the toothbrush was invented? | As I understand it we used to chew on sticks and animal bone. The stick would fray at one end when chewed and provide a sort of brush.In the middle ages in the UK I read somewhere that people used to chew coal but I cannot find the link.The toothbrush we know today was apparently invented in 1400's in China and used pi... |
Why do I, along with a lot of people I know, find it far more natural and convenient studying from printed papers rather than from a computer screen? | Another answer is that flicking back and forth between pages on computer is very cumbersome. On paper you can potentially lay out multiple sheets across your desk for easy reference. There is a study that shows even just a second of being distracted causes your brain to lose focus.

Why is swallowing toothpaste so bad? | Flouride is the conjugate weak base of the weak acid hydroflouric acid. If you swallow fluoride, it will change the pH of your gut. It will make your gut more acidic, potentially killing bacteria and enzymes. I would bet your digestive system isn't optimal. If it's been going on for 15 years I'd bet you have some prett... |
Why did the Concord stop flying ? | For two reasons. Firstly, was the France disaster, where a Concord took off, suffered some major malfunction, and wound up upside down on the ground, with everyone onboard dead. While it was a genuinely magnificent plane , such a well-publicized disaster occurring to one of the very few Concords in the world killed the... |
How did US politics become so divided down partisan lines? | The question doesn't really have a specific answer. There isn't really a singular answer as to when the Democrats and Republicans became so partisan. In recent history, the rise of Gingrich in 94 and subsequent actions really pushed the parties apart. The Gore/Bush election in 2000 and the rise of Fox News further pola... |
The Twins (Lucy and Maria Alymer) who are different races | Because they're not identical twins. It would be very strange if they were identical and looked that different. For non-identical twins two eggs are fertilized separately by two sperm. They're essentially normal sisters who just happened to be in the womb at the same time. And just like normal sisters, they can look ve... |
Why are (domestic) cat's noses so much stronger than people's, when a cat has a nose the size or a dime, and ours is the size of a pepperoni? | Because you don't use your nose to smell, you use a patch of nerves in your sinuses . On humans that patch is relatively small 2-4 cm^2 while it's considerably larger on many animals ) some dog breeds have up to 150cm^2 and both have millions more nerves in the patch). It's smaller in volume because yours is fairly fla... |
Why is it that when we think about breathing, we generally start to breathe manually? | If you notice your foot tapping, then focus on it and think about it, it'll stop. When you breathe subconsiounsly then think a out it you become aware and in control. Same idea. |
Why do all local radio and TV stations use random letters to name their stations? | Also before the internet and all the good things that come with it, callsigns were crucial for identifying what station you were listening to. You might be picking up a CBS affiliate, but which one. Depending on conditions you can receive TV and radio stations from all over the country. Without a callsign it would be c... |
Why is day trading of stocks a thing if its essentially a zero sum game? | Trading creates value for society by moving money around from places that destroy value to places that create value . This extra value created actually strengthens the value behind money - it increases it's purchasing power! Day trading still does this, at smaller intervals/increments of time. Consider a million dollar... |
If I stream a 3.5MB song versus download it to my computer. Is the data usage exactly the same? | depends what the program downloads with it. if it is downloading a bunch of album covers and extra information, there may be some extra data downloaded when streaming. also, going a bit deeper, streaming could end up using more bandwidth due to overheads in the transport mechanisms. again, depends on how the program im... |
If humans and dolphins are the only mammals that procreate for fun, why does my dog hump my leg? | > If humans and dolphins are the only mammals that procreate for fun As opposed to other animals, who have a family and career in mind and plan accordingly. But seriously, that whole 'only humans and dolphins fuck for fun' is bullshit. In fact, I'd wager it's the other way around, we're probably the only ones who fuck ... |
What the hell is going on with Verizon data plans? | according to the verizon site 50 bucks gets you 5gb. there's no 1gb plan but 30 bucks gets you 2 gb short answer is that the infrastructure can't support 4g and lte speeds. a few years ago, when most phones were running 3g or slower, it wasn't easy for most people to go through 2gb worth of data. as 4g phones and data ... |

But if you go to the pet store you can get toot... |
What could possibly be in the great depths of the ocean that we haven't explored yet? What are scientists thinking that could be down there? | We estimate we've discovered less than 10% of marine species, most of them are going to be in the deep sea. There's also massive amounts of rare metals that are becoming closer to being economically viable to extract, so mapping the seabed to find them is important to geologists. Biologists then need to make sure that ... |
Why are teeth individual, and were they ever one whole solid unit? | It's a lot easier to replace a single broken tooth, or deal without a tooth, than to deal with a broken or missing 'mouth plate'. Anyone who's had a toothache can tell you how painful it is - much better to remove one tooth than to have it over the entirety of a jaw. |
