As Christmas is around the corner, can someone please explain why Jehovah's Witnesses don't celebrate it? | Jehovah's Witnesses don't celebrate Christmas because of a few reasons: Jesus commanded to commemorate his death and not his birth. Early apostles and disciples didn't celebrate Christmas. There is no proof Jesus was born on December 25th. They believe Christmas isn't approved by God as it is rooted in pagan customs. T... |
How did dinosaurs become oil? | They didn't. It comes from small marine animals and other life that lived before the dinosaurs. When they decomposed mostly carbon and hydrogen was left over, as the oxygen was removed over time the left over remains were covered by layers of sediment. As they got deeper in he earth, around 3048 metres, or 10,000 feet,... |
3D Printers. How do they work? What's used for "ink?" | They do work. It's kinda like a really precise hot glue gun. They use plastic that's melted down and then put in the shape that a computer tells it. |
Why are there no international laws prohibiting excessive forms of capital punishment (stoning, crucifixion) | Because countries have to agree to it just like war laws and the Geneva convention. Why would a country that stones people to death agree to a law that says not to do so?The issue isn't "we need a law ", the issue really is "who is willing to commit troops/money/time or risk money/economy to enforce existing laws". Too... |
how do precision induction cook tops work? | Induction cooktops work by generating a powerful oscillating magnetic field that vibrates the molecules in the pot sitting on top, which in turn causes the metal the pot is made out of to heat up. Since they operate on pure magnetism, the pot or pan used has to be made out of a magnetic material - cast iron, steel, or ... |
How do banks know if a check has already been deposited? | The bank that has to pay the check usually has software to notice duplicate checks. Once a check is used once to withdraw money from the account the check info is saved and if the same check is used again it should be flagged. Say you use Check #1023 to pay me $100. Once the check is processed, it will be marked on you... |
Do animals that utilize camouflage prove they're self aware? | Usually when we use the term "self aware" we mean consciously aware of, and having the ability to reflect, on our self -- in particular our mind. However, no such self-reflection is actually needed for camouflage necessarily, as it can a subconscious reaction, honed in millenia of evolution's trial and error . Some ani... |
how do I recognize an object? | I don't know weather this could be explained fully at the moment. It's to do with rather complex processes and interactions between different parts of your brain. First your visual cortex puts together a picture of what you see. It turns all the signals from your eye and optic nerve into a picture. The second step is w... |
How do scientists know that they've found 90% of near earth asteroids? | This is an estimate based on the number, density, and size distribution of the observable objects. Given that they have found X number of asteroids of different sizes, and that there are so many within a certain area of space, and that number is much less in other areas of space, they can estimate about how many they t... |
How can multiple people watch the same online video at once? | While the video is being played back it's read into a server computer's memory chips temporarily. From there it can easily be read many times per second to serve multiple users. If huge numbers are playing it, multiple servers are used. |
How will transmedia culture affect future careers? | Career paths are almost never meaningfully affected by the introduction of technology. For instance, the structure of the animation industry has stayed basically the same after the introduction of computers. People do months of horrible unpaid work and years of horrible badly paid work in the hopes that they will be on... |
Why did the Soviet government change their opinion on Shostakovich after the 5th Symphony? | Shostakovich fell out of favor with the Soviet government because his works were at odds with their notion of how classical music should sound. The Bolshevik authorities wanted artists to create works that could easily be appreciated by the masses, and Shostakovich wasn't doing that. His work was dissonant and not espe... |
How do phones and cell-towers deal with the Doppler effect? | It doesn't matter The Radio waves are moving at 3x10^8 m/s, thats 300,000,000 m/s. If you travel towards a cell tower at Mach 10 you'll be moving 3,430 m/s and change the wavelength by 3,430/300,000,000 or 0.0011%. You're not traveling anywhere close to Mach 10 so the impact is truly insignificant |
Why does the shower change temperatures if you flush the toilet while the shower is running? | Because the temperature of your water is set by mixing hot water and cold water. The toilate and shower often share the same source of cold water, flushing the toilet means there's less cold water available to the shower. So the nice mix that you had so carefully created, is all of a sudden has way to little cold in it... |
Would creating a matrix disprove the theory that we could be living in one? | If anything it would add more credibility to the theory, as it proves that a lifelike universe is possible. And no, the new matrix citizens can create a simulation of their own matrix. Surely it won't be an exact simulation of their own universe, but neither can ours be . Computationally, it's no harder to simulate the... |
What makes a great conductor great? and conversely what sets them apart from a random high school band teacher? | It's important to keep in mind that a conductor is nearly always the leader of the orchestra, too. So for weeks and months before you see him/her waving a baton around, they were in charge of auditioning band members, selecting the music, organizing rehearsals, making artistic changes or interpretations to the piece as... |
Why does poop, urine, sweat, etc. smell bad? | Many animals have evolved to not like the smell of poop because poop is not nutritious and is full of bacteria. The animals who didn't think poop smelled bad probably died from the bacteria. The animals who developed by mutation receptors in their noses that recognized toxins in poop avoided the poop and lived. These a... |
It is generally common knowledge that psychics are scams, my question is how do they still make enough money to keep their business going? | Not everyone accepts the idea that they're scams. Even some people who accept that they're scams find it fun.As P.T. Barnum said, there is a sucker born every minute. That is how.If you needed to appeal to the majority of the population, there would be no niche businesses at all. Most people don't play the piano , but... |
Sometimes when I click on an imgur link, it sends me to an unrelated image. Why is this? | If you're clicking on an old imgur link, it could be that the original image has timed out. I believe imgur holds onto images for 6 months from the last time someone linked to it and then recycles the code. For example, lets take [this image] on the front page of imgur right now. It's coded **bDk9o2A**. If 6 months pas... |
Why there is so much hate to Comcast? | They have a near monopoly position on an 'essential' service. Their 'near-monopoly' is due to the way the US telecom/internet industry is structured. They lobby to keep it that way. They also abuse their position to maximize profits at the cost of customer well-being/satisfaction. This works because customers really ha... |
How does distillation work? | In order to distillation to work properly, you need two different liquids mixed together - one very common distillation is water + alcohol. Now water becomes gas at 100°C, but alcohol has a lower boiling point around 78°C. This means that if you heat the mixture to, say, 85°C, all the alcohol in it will become gas whil... |
How's the calculator industry doing since the rise of the cell phone? | Just fine. Most high schools still use the same TI graphing calculator I used 25 years ago and charge a shit load for them. Also, using a smartphone for rigorous calculation sucks. |
why do dvds look so much better and crisp on CRT TVs then on HD flat screen TVs. | The difference will be almost all down to HD flat screen TVs being bigger than CRT TVs. Tell us the size of the TVs you are comparing. Blowing up an image to a larger size will make it look more blurry and reveal other imperfections. If you could make a fair, side-by-side test with a CRT and an LCD panel of the same si... |
How does the Monte-Carlo method work? | Let's say you have a white piece of paper and a black marker, and you color some areas of the paper black. You ask me to figure out what fraction of the paper is colored black. Let's say I already know the area of the paper and that this doesn't change. One way to figure this out would be to precisely measure, using ge... |
In the US, why are alcoholic beverages not required to have the same nutrition fact labeling as other foods and beverages? | Food is under the Food and Drug Administration which does the nutrition labels. Alcohol is under the Alcohol, Tobacco, and Firearms , which does not have a labeling standardIn Canada and as someone on keto, I appreciate that Sleeman clear has nutritional facts despite not having toDue to the way alcoholic beverages are... |
Why are some of my dino nuggets ice cold and the others lava hot, even when I place them in a circle? | A microwave produces [standing microwave waves] inside it to vibrate certain molecules in food to heat it up. The issue is that the wavelength of the microwave is about 12 cm long. Due to the nature of the standing wave, this means that there are spots where the waves cancel out every 6 cm . The cold nuggets are sittin... |
why is it that when food is too hot to touch it doesn't necessarily burn your mouth when eating? | Because the inside of your mouth is already around 37C and coated in slimy film, where as your hands are dry and have a surface temperature relative to the air temperature. If you dipped your hands in say..slime, they could also pick up hotter objects. Your hands and other sensory organs are wired to tell you "this hot... |
why are animated gifs substantially larger than mp4 videos? | An animated GIF is a series of images stuck after each other, like an old movie roll. So you have all the data of all the frames: Frame + Frame + Frame + Frame + [ .] + Frame. An MP4 video is a repeat of a full frame image followed by a series of incremental frames which show the differences with the full image. So you... |
Why do people instantly grab/press a body part which just got hit/injured? | I would assume people do this to prevent further damage to that body part. For example, if you are in a fight with someone and they punch you in the left arm, you would cover it to try to block more damage from happening. It could also be for applying pressure on a wound to lessen the bleeding. |
Why are some websites updated with "© 2016" at the bottom while others may say "© 2012" or whatever year, when clearly they're still copyrighted? | The copyright date establishes the beginning of the copyright . If I write something in 2012 and never change it, it stays with that copyright and it will eventually come out into public domain. If I continue to update the same site or information, the copyright updates as well and pushes back the date when I loses cop... |
Where does the battery "juice" (or charge) in my laptop, phone, etc. go when it runs out? | It is converted into kinetic energy used to spin your hard drive, heat from the various components in your computer operating, light from your monitor and from the various indicator lights on your laptop and the various laser reading heads on different devices you may have, magnetic fields as you write new data to your... |
Why do businesses seem to be stingy with ten-dollar bills? | Often they have few if any to give. The thing is, fives are more versatile since they can break tens or twenties, but tens can only break twenties or higher. Higher than twenties the next up is fifty or a hundred, so youre better off breaking with twenties and fives . Considering most bills arent going to need flat fif... |
What happens to the animals killed during crop harvesting? | A farmer friend of mine said, yes they do occassionally clog up the works but for the most part they end up in the harvester, and caught by various filters, and by the sorting devices later. Larger animals, once freed , are often tossed off to the side for the predators/scavengers. Animals around farms are often smart,... |
Why is disinfecting wounds painful? | There's two main reasons. First, the wound is sensitive, as that part of the body has been damaged and is screaming at your brain to start taking damage control steps. Putting anything in an open wound is going to hurt some. Second, the things we use to disinfect typically do that by killing biological material, which ... |
When there is a catastrophic injury to a person's head, why is there a delay before blood starts pouring out? [NSFL] | It isn't just the head but most flesh that reacts this way. An injury usually happens when force is applied to the flesh and this tends to compress it before tearing it, which pushes blood out of it into the surrounding tissues. Imagine if you forced a rod through a sponge; it would tend to squeeze the water out of tha... |
How are exchange rates decided? Who decides the actual numeric value of one currency in another? | In the modern economy, most exchange rates are determined essentially by supply and demand. For example, if you are American you are paid in dollars, but need Euros to buy goods produced in Germany. When you want to buy a German good, you are "demanding" Euros and "supplying" dollars so the value of Euros increases rel... |
Cold temperatures wake us up while hot make us tired, is this purely a matter of comfortability or is there something happening to our bodies? | [There was a study done] and it says the optimal sleep temperature is between 60-68 degrees farenheit. Too warm or too cold and you can become restless. It's interesting that warm temperatures make you tired, the opposite rings true for myself. |
What do they mean when they say the mass of the atmosphere of Pluto has decreased by a factor of 2 in two years? | Uhhhh, Pluto is heading into it's hundred year 'winter' season. The atmosphere is freezing to the planet as ice. It's a 'dwarf' planet equivalent of a comet . Everyone saying it's lack of gravity is missing the fact that that process takes eons, not two years.Pluto was recently at its closest approach to the sun. It ge... |
why wired data transfer is faster than wireless. | I think it's mostly because wireless transfer is more prone to interference - it's very difficult to corrupt data that's being sent over a wire, but it's very easy to corrupt it if it's sent through the air. Particularly if there's any sort of obstacle between the transmitter and the receiver. Sure, any computer worth ... |
Why are search boxes in many websites so seemingly innefective, while googling the same thing almost always gives me what I was looking for? | Google has been optimizing their algorithm for a long time. It uses all of the past searches everyone has ever made using Google in order to learn what results people are most likely to click on, and then offers those results ahead of others. Because Google is popular, a lot of people have used it, and so they have a l... |
Why are baby animals so cute? Is there a genetic advantage to this? | There is some belief that traits we identify with 'cuteness' are traits possessed by immature animals, and as such there's a protective/friendly hardwiring in the brain. The advantage would presumably be that immature animals are less capable of caring for themselves, and therefore those that are cared for by adults pe... |
What is ASMR? Can anyone describe what it’s like? | It stands for Autonomous Sensory Meridian Response. Basically, it's a physical/physiological reaction to certain sounds. These trigger a tingly sensation esp on the spine and head. It can also be used as a relaxation technique. Others have a sexual response to it. So it's kind of the reverse of nails on a chalkboard So... |
How is it I can spend 3 hours laying still in bed not sleeping, then doze off repeatedly in the middle of driving the next morning? | Are you saying that you actually doze off while driving? *Repeatedly?* This is not normal and is a grave concern to me. I have never dozed off while driving. You should not be risking your life and that of other drivers that way. I'm frankly totally shocked. If something like that happened to me, I think I would see a ... |
Why are we charged 9/10th of a penny with gasoline? | In addition to the other posts, another reason is that gasoline profit margins are extremely tight but high volume, and it adds up. In 2014, it ended up being an extra $1.2 billion in revenue. via [source] |
If I let two chess engines play each other 100 times, how do they play 100 different games if there must be one optimal game? | There is a field of Computer Science called "Computation Theory", which is adjacent to AI. With our current computation power, we aren't even able to solve a single chess opening , let alone the game itself, so while working with Computation Theory has advanced our understanding of the game very much , we still don't k... |
How does a cars speedometer know not to increase when a cars tires are spinning? | It does not know. It assumes the tires are in proper contact with the ground, and when they are not, it gives an incorrect reading. Future speedometers may be corrected using GPS, but that generally is not done today.I haven't worked on a newer car, but on older cars the speedometer is driven by a cable/gear on the tra... |
How do burning arrows stay lit after the immense acceleration they experience being shot from a bow? | Depending on the fuel used, it can be almost comically challenging to put it out. If you've ever dealt with a gas fire, you'll know what I mean. I'd wager they were using coal-tar or peat or natural gas of some sort -- though I'm a little out of my depth here. |
How is the US allowed to just raise tarrifs when laws that have minors effects on trade have to go all the way through the WTO? | The premise of your question is mistaken. The European Union has initiated a WTO case against the US over these tariffs. |
Why do we use the base 10 system, and what are its benefits over other mathematical systems? | no benefit, other than a convenient correlation with the number of fingers. there are better systems that work better with the base 2 of computers and which have more easily divisable fractions. Base 16 would probably be an ideal candidate for both things.tl;dr: The decimal system came to be bacause humans have 10 fing... |
how does hand sanitizer make your hands clean when you don't use anything to wipe the dirt off them? | Hand sanitizer is not the same as hand *cleaner*. Its only function is to kill the micro-organisms on your hands. There are certain gels called hand cleaners that work like a pencil eraser though. Those ones do actually clean your hands by trapping dirt and then flaking away as you rub them together.Well, it doesn't ma... |
The crucial difference between operating systems (Windows, Mac OS, Linux etc...) | Windows - > Expensive. Sort of easy interface with many "advanced mode" options. Closed source. Solid ubiquity and compatibility. Mac - > Very expensive. Easy interface with less "advanced mode" options. Closed source. Poor ubiquity & compatibility with some industry pockets of ubiquity & compatibility. Unix - > Price ... |
If someone gets arrested but is later found innocent, why does their arrest and initial charge remain on the NCIC's database? | if there is no record that it happened then the government might think they forgot to arrest you or something. if you are found innocent you can remove it from your publicly viewable recordMost people will never see a complete report from someone's criminal history on NCIC. I use it as part of my job, and see them dail... |
How is it so difficult for video game publishers to detect cheating on PC? | The fundamental problem is that the user has physical control over their own PC and the only information the game manufacturer gets is whatever their PC sends. > Doesn't their code have digital signatures? Sure, and those can always be defeated someone with enough time and perseverance. Let's say the code is running on... |
why certain surgeries require months of recovery time | Well, it really depends on the part of the body being operated on. Different types of cells in different areas of the body replicate and replace at different rates. A neuron, for example, can take as long as 7 years to replace itself . Shoulder muscles can take months to repair themselves. Surgeries are great. They can... |
Why do Japanese albums often contain bonus tracks not available elsewhere? | There is complex and lengthy process to be allow to sell albums in Japan. This leads to the fact that most of the time, album are release in Japan later than in other country. To make sure people wait for the japanese release and don't just buy stuff abroad through internet, companies put exclusives bonus tracks in the... |
Where does the term "the birds and the bees" to explain sex-talk came from? | Birds and bees are good animals to use to discuss sexual reproduction with children without the need to talk about sex itself, using processes that children are likely familiar with. **Birds** lay eggs, which is similar to female ovulation. **Bees** deposit pollen into flowers, which is similar to male fertilisation. H... |
how do we know when our sun will go supernova? | Our sun will not go supernova, and when our sun begins to die, it will go big and red. We know this due to calculations that we do and observations.Our sun doesn't have enough mass for that. It will eventually swell into a red giant and eventually putter out into a dwarf. Unfortunately no massive explosions involved. |
Why do people give Al Gore credit for inventing the internet? | They really don't. Some people say it as a joke, but that's it. [The snopes article has more information.] You only need to read the first three paragraphs. |
What exactly is happening when a black hole 'burps'? | Around some black holes an accretion disk is formed. This is basically just a disk of gas orbiting the black hole, sometimes it comes from a companion star. As this gas orbits and moves towards the black hole, it is superheated, and this is what is causing the xrays. The xrays are not coming directly from the black hol... |
How was the Apollo 11 landing different from say the current Space X landing. | If you are referring to it's return to earth, it deployed parachutes and splashed down in the ocean. Here is the video. _URL_0_ The difference between SpaceX and Apollo 11 is that only the crew re-entry vehicle was recovered. The rest of the ship separated during launch and burned up on reentry.For one, the LEM could a... |
ELIA5 the "War Z" fiasco, please. | The game has been released and is in really early development. A lot of the features being advertised are not in the game [yet?]. People think it's false advertising and are unhappy with the end product. |
what prevents dangerous mold from growing on cheese during the aging process? | During normal aging-for-production, no mold will infect the cheese by itself. Shortly after "creating" what will become a cheese, it is separated from the surroundings by rubbing a special, very salty solution on its surface frequently . Cheese which isn't treated that way frequently gets bad quite fast. For special mo... |
Why did the DEA decide to make CBD a schedule 1 narcotic? | Because there is a long history of pharmaceutical companies lobbying to have anything that might take some of their money made illegal. CBD oil is making headlines and deserves to be researched. By lobbying to have it made schedule I, there will be little to no research done in the U.S. ensuring that we will have to bu... |
Why is Carfax, a commercially owned company, allowed to collect all kinds of information on our cars, and sell it to others for money? | Every bit of information that is on Carfax is either: 1) Not information that qualifies for privacy protection 2) Information that is already public - this includes police records 3) **Information that, somewhere down the line, you agreed to allow another company to sell**, likely in a very long sale contract, online a... |
Why do some belly pains only go away after using the toilet/restroom? | The pain in those cases are caused by pressure. Like a blocked pipe, enough pressure can cause issues, and also like the pipe, if we unblock the way and get rid of the stuff causing the pressure, the pain goes away. |
ISIS, sunnis, shias, and why didn't Muhammad leave behind a predecessor? | Sunni Muslim here. I'll try to explain the situation as I best as I can but sorry if I fail to help you understand since this a very deep and old conflict. Allah knows best. Muhammad was the leader of our people. In his time there was no Sunni or Shia, his followers were simply Muslims. The trouble started when Muhamma... |
Who decided that we need exactly 12 years of grade school? Seems like kind of a random number to me. | OP, /u/Teekno has some decent points, but his information is a bit inaccurate. Unfortunately, all the people arguing over his inaccuracies have failed to actually fill in the holes those inaccuracies present in answering your question. The PRIMARY reason that school ends when you turn 18 is because 18 is the age that U... |
What, exactly is happening when I have diarrhea? Why is liquid falling from my butt? | Whenever you eat food or drink water, your stomach begins to digest it and produces a liquidy substance called "chyme" which is essentially just partially digested food. This is then released into your intestines where eventually the nutrients and water will be absorbed. So when you eat something that your body recogni... |
Surviving a freefall into a body of water | Under best conditions, any, up to and including world record edge of space, because terminal velocity and "best conditions". A human being trained to skydive can assume a position that lowers their terminal velocity to somewhere around 150 mph. If they can properly time a flip into a feet-first dive like a water-slide,... |
How are credit card numbers validated? | The first step in that the first few digits will be checked to correspond to a certain company. For example an Amex card will start with 34 or 37 and will be 15 digits long. Where as a Visa will start with a 4 then the next 3 digits describe the issuer and card type, it will also be 13, 16 or 19 digits long. If it then... |
How come when I'm driving and I stop at a light the road seems to keep moving? | Tunnel vision. Perhaps, while you are driving, you should take notice at your surroundings more frequently. Keeping your eyes on the road ahead is good, but it's equally important to be aware of everything else around your vehicle while on the road. |
The U.S. President just said in his Weekly Address that the U.S. Air Force is the smallest it's been since 1947. How is that possible since the AF was established in 1947? | Because the US Army Air Force transferred all assets and personnel to the US Air force upon its creation and in 1947 they had a lot of assets having just finished fighting WW2. More pertinent should be just how stupid that talking point is in terms effectiveness. If you only measure the effectiveness of any branch of t... |
What are crazy long math equations used for, and what do they solve? | Not everything that is worth doing can be described simply. For example, suppose you want to do something simple, like come up with a mathematical model to figure out how much snow will be on a road a few hours after it has snowed. To be able to decently capture this, at a minimum you will need to include: * temperatur... |
How much executive power does the PotUS have to launch nuclear weapons? | All of it. They do not have to get the permission of anyone to launch a nuke as they are the commander in of the military and are the singular authority over them. It is possible for someone in the chain under him to disobey orders, but that is not likely. During military activities there is not time to call a session ... |
Is water truly a renewable resource? I know we have a lot of it, but could we ever run out? | Water is absolutely a renewable resource. That is to say, the same amount of water is "on" planet earth constantly. The issue, and what causes the droughts, is the reallocation of liquid water as well as water moving from one state/phase to another and being trapped there longer than it "naturallly" would. Both of thes... |
Why do names tend to cycle in and out of popularity throughout different generations? | "That's an old person name, I know an old lady at my work who is named that it's so icky" or "Haha gross I can't name my kid after my dad" "Haha gross I can't name my daughter after my gramma" "Oh man, wouldn't it be great to name my child after a relative I barely know to honor who they are as a person?" At least, tha... |
why are old jugs or bottles of liquor commonly shown labeled with three X's? | It's typically a numbering system for jugs of moonshine- the number of Xs is the number of times the mixture was runn through the still before being bottled- XXX indicates it was run through 3 times, which means the moonshine inside is pure alcohol.If I remember correctly, the Xs were to show how many times the moonshi... |
What happened to time itself during the earliest stages of the big bang? | "So, isn't the universe older/younger depending on from where you view it? " Since by definition you are part of the universe, you cannot \'view it\' from anywhere else. The idea that you can must therefore be a fiction. Likewise, the idea that there is a detached \'point of view\' also has a non-empirical basis and co... |
Why is Nickelback so hated? | The main thing for me is how ridiculously similar their songs are. I mean, I understand having a signature "sound," and Chad Kroeger definitely has a distinctive voice, but for some reason they can't seem to come up with anything new. Oh yeah. One example I found is this clip of two of their songs, each playing on one ... |
Does Mary Kay really give their best employees pink Cadillacs, and if so, how can anyone possibly sell enough makeup to pay for a Cadillac and still make the company a profit? | Yes they do actually give you a pink Cadillac CTS they are usually the women at the top of the local pyramid, who have recruited a large amount of members.You don't make money selling the makeup. You make money convincing people that selling the makeup will make them a ton of money, if they would just spend $100 for th... |
If Reddit is not paying sub-reddit moderators, why are they working on Reddit, unpaid? | You can look at it from the point of view of the mods giving a free service to Reddit, or you can look at it as Reddit giving a free service to the mods. It's totally possible to run your own message board. But you would have to pay for the webspace, you'd have to learn how to install and maintain the messageboard back... |
Why is it called a pair of jeans when there is only one? | Pair of pants . Back in the middle ages, the hoses were kind of put on separately. The phrase stuck for 500 years after it stopped making sense. Go figure. |
why are scientists trying to clone a wooly mammoth using ancient DNA when they could be cloning endangered animal species, such as the white rhino, whose DNA we can still collect? | As has already been said, there are research efforts focused on both. However, tackling the technical challenges of piecing together a genome that hasn't existed for thousands of years would benefit the scientific community more than trying to keep a species alive that nature can no longer support. Sequencing the mammo... |
How does something like a drill speed up the harder you pull the trigger? | The trigger is attached to something called a variable resistor. As the trigger moves a metal contact plate slides along the resistor. There is a small power supply that sends a voltage through the resistor. The electricity flows through the metal contact into the resistor. As the metal contact moves, the electricity h... |
Why do a lot of people love the smell of gasoline? | There are a couple reasons. 1. It gives you a tiny high. Just like huffing, it provides a mild anesthetic effect and gives a slight feeling of euphoria. 2. Associations. Smell is the sense tied closest to memory, so if we have positive connotations with the use of things with gasoline engines, we will get a positive fe... |
Could someone explain to me who Rick Perry is and what he has done/is doing to make him so hated on Reddit? | Rick Perry is the current governor of Texas. He has demonstrated beliefs that are very conservative, though that by itself is not the problem. Rather, Perry is like the guy that always raises his hand in class and says "that's not what my momma said." When faced with scientific evidence he'll bulk claiming that science... |
When someone gets rushed into the ER like they do in the movies, what do the doctors do to save that life? | This is entirely situational. Arrest blood loss, restore normal rhythm to the heart, take a two-by-four out of someone's rib-cage and lung. It depends on what the nature of the insult to the arriving person is, and the 'everything' is basically 'reasonable measures to repair that insult, or sustain the injured who has ... |
If the original patent for the fire hydrant was burned, then...can I patent the fire hydrant? | You run into the problem of prior art. In short, [if it's been done then you can't do it]. |
Ion water/alkaline water recent health fad ? | Water scams go back quite a ways. There are no really new ones, because just about anything you can think of has already been done a thousand times over, including all the various combinations thereof. And they are all pseudoscientific garbage. Finally I've found a place to link [to this site.] I knew it would happen e... |
Why is network speed measured in bits but storage size in bytes? | Because when information is transmitted over the network, extra bits are added to tell routers where each packet needs to go, and to add coding that will help minimize transmission errors. So it isn't quite right to take the number of bits/second and divide by 8 to get the number of received bytes/second. Also, Marketi... |
Pros and Cons of Verizon entering the Canadian market | Traditionally Canada has been very protective of its own telecommunications companies. For the most part, it is completely illegal for foreign telecoms to operate in Canada. The fear is that if foreign telecoms started operating in Canada, they would end-up taking tons of jobs and customers away from Canadian-owned tel... |
Adding halves of halves forever | No, you won't, not in that situation. You'll have something like, as time approaches infinity, ruler approaches 12 inches. At that point, you'll be increasing the length by infinitesimal - ly small increments. It's called Xeno's Paradox, and it's fun.You will approach 12 inches. What that means is that you will get rea... |
How did Helen Keller learn anything when she is missing the two most important senses involved with learning? | She got sick as an infant, IIRC. It was hard for her, she was eventually able to make the connection between the smooth sweet tasting thing and the hand movments people kept making in her hand. The issue is that you're too reliant on those two senses. Yes, they're very important, but a human can survive without them in... |
Why do things smell stronger when they get wet? | A - Because you reek of smoke all the time but have got used to it so you don't notice. And B - the water is evaporating taking the smell into the air with it, combined with the moisture in the air "traps the smell" better than "dry" airYour nose can smell better when the air is humid. More moisture in the air = better... |
Why does my phone take longer to charge than the actual time of me using it? | It depends how you use it. Let's say you make a phone call here or there, check your email a couple times - the battery should last you a day or so, remaining on standby the rest of the time. Now a different case. You start playing Angry Birds, and then shoot a lot of 3D video, playing it back constantly. You're also i... |
Who gets to decide what to name a newly forming Hurricane? | Nobody does! The names have already been chosen. The National Hurricane Center has a list of names that they cycle through every 6 years. You can look at it [here.] The first tropical storm of the year takes the \'A\' name at the top, and later storms just go down the list. The most recent tropical storm was named "Don... |
How come surgeons can slice you up like a Christmas ham and there's minimal bleeding? | They can either use something called electrocauterisation, which is where they heat the tissue with electricity in order to burn and seal blood vessels, or they can 'tie off' blood vessels using ligation.When you cut your finger with a knife, there is a large amount of blood due to the large number of small blood capil... |
Why does Reddit care so much about privacy? | I think most people are ok with governments having the physical capability of tapping a phone, intercepting email, and other such suveillance. But they want that power to be safeguarded behind court orders for specific cases. > Am I naive for thinking the government doesn't really care about most of the illegal stuff I... |
If a person can't be put on trial twice for the same crime, what prevents people who committed a crime and did not get sentenced, openly talk or discuss the crime? | They can still be sued by the estate of the deceased. Like OJ - wasn't convicted of murder, but had to pay a shitload of money to Nicole and Goldman's family.There are crimes you can be charged with that go along with the murder: illegal possession of a weapon, breaking and entering, trespassing, reckless endangerment,... |
-How is life possible? | > Life itself contradicts this goal. In our bodies at every given moment chemical reactions are going on that send these atoms UP the stability gradient. HOW?! Because of constant energy input from the sun. You appear to be talking about the concept that entropy always increases. But that only applies to a "closed syst... |
