During the week they're in school. Sundays, might have church... |
What is CERN and what real problems can it cause? | CERN is basically trying to find out the origins of our universe and how everything works by using a very large particle accelerator to accelerate particles to 99.99991% the speed of light and have them collide with one another. When these particles collide they break apart and that is when we can see what holds partic... |
What is the process of photographers when taking pictures of the supermoon? | There's really not much to it beyond needing that longer lens to zoom in more. Since the moon is being lit up by the sun the exposure times are just like taking a picture of anything outdoors in the middle of the day so it can be a handheld shot. Think of it like wanting a picture of a specific person's face in the oth... |
Why do we drink cow's milk instead of human milk? | Human females can't produce the same quantities of milk that female cows can. It wouldn't be very profitable. Plus, notice that we mostly drink milk that comes from animals that like to graze on grass, like cows, goat, and sheep. Humans eat a lot of junk food and other stuff that doesn't make for very good tasting milk... |
In Sci-fi movies, why are alien organisms almost always silicone based? | Silicon is the other element other than carbon that would form long complicated bonds that life could evolve around. Though it is almost certain that another life form would be carbon based this gives a way of creating a "totally new life form".It's silicon .. Not silicone. Silicon is the next element after carbon with... |
LI5, the current patent controversy between the top tech companies Google, MSFT, Apple, etc. | Before the 80s software was covered by copyrights instead of patents where unless you copied something exactly you were not liable to be sued for stealing someone's ideas. However large companies wanted more protection of their software and after some court cases including some at the supreme court they changed the rul... |
Why do different cheeses made from the same type of milk have different Calcium values? | It basically comes down to pH value of the whey and it's drained. Casein is bonded by calcium phosphate and as the pH decreases it becomes soluble and is drained away. |
Why does water cause a near perfect hexagon bokeh on camera lenses? | > Basically, how is this caused, and why the hexagon bokeh is always perfectly shaped? Both of those answers are because it is the shape of the lens aperture of the camera. [This link shows what structure is causing the shape.]', "I don't believe its a characteristic of the water. It's likely the shape of the cameras a... |
what causes that distinctive smell from electrical transformers, such as model railways? Somebody once told me it's ozone, but why would that be produced? | You get the same thing from lightning strikes. The electric potentials involved have enough energy to break the bonds in ordinary molecular oxygen and some of the free oxygen atoms can reform to ozone . You need energy to do this because it tends not to happen spontaneously, as the O2 molecule is a more stable molecule... |
How does insane Clown Posey have such large following, who are willing to do anything for the band? | Because persons are smart, people are dumb As some comedian said, imagine what average, I mean totally middle of the road intelligent, person is like.

- if pi is in between the number 3 and 4 how can it be infinite? | It is *not* an infinite amount. It is less than 4. In *does* take an infinite amount of digits to explain precisely what the amount is, but that's about being precise, not about being huge.Pi isn't infinite - it's more than 3 and less than 4. However, pi can't be expressed as a decimal or fraction because it's irration... |
ELI5:Why is it that a small animal will run up to a big animal and fight it and the bigger animal will run away? Do animals not know their size? | Because the question in the wild is not so much if you win, but if you get injured. If the large animal stands and fights, yes, it might kill the small animal, but maybe the small animal takes a chunk out of the big animal's leg. Then the big animal has a gimped leg, can't run, can't catch prey , and it likely dies. |
What do medals in the Olympics actually do for the winner? Also, what happens if a country wins the most medals? | They don't "do" anything. Medalling is proof that you are among the best in the world at your sport. That can help you get sponsors and endorsements, and it can help you leverage a post-sports career in something like journalism or broadcasting if you play things right. But there are no special privileges or anything t... |
Why do doctors stop applying a defibrillator after a couple of tries? | Same reason you don't keep turning the ignition key for hours in your car when it won't start -- there's no point in doing it, it won't get better. |
Can someone explain how and why Mark Rothko's work is considered art and how I can appreciate them? | Have you ever seen a Rothko in person? It makes a huge difference. First and foremost, they're BIG paintings. Second, he always wanted people to look at them up close. IIRC he said the ideal viewing distance as 18" . When you're that close to a huge painting, you literally can't see anything else. Your entire field of ... |
Smartphone "rooting" and "crapware." | "Crapware" refers to all of the pre-installed apps that you don't want, but the device will not allow you to uninstall. "Rooting" means basically taking control of the device in such a way that you can do things that it normally doesn't permit you to do, including uninstalling "uninstallable" apps. The term comes from ... |
Why do radio stations only end in odd numbers? | Because of the way radio technology works. The station you pick isn't actually what you are listening to, you're listening to a range or band of frequencies, rather than just one.The name of the channel is based on the range of frequencies assigned to it, in terms of the actual frequencies being broadcast to make that ... |
; Bohr vs Einstein puzzle solution. | The correct answer is that you have the same amount of B in A as there is A in B. Consider this: each container has 100 units of liquids A and B.

How do brands manufacturing non-concentrated, natural fruit juice keep the taste constant? | I'm not so sure they do. I drink apple juice, grape juice, and orange juice and I notice they do change in taste year in and year out and also season in and season out as the source of the fruit changes as seasons change in different parts of the world. So answer is, they don't control it. Some batches are better than ... |
When people talk to animals or babies, why do they tend to talk in a high pitched cutsie manner, and never talk like they would normally? | The heck where are the comments? The behavior is called mirroring which we humans have accepted as affectionate behavior. When babies babble in their cute high pitch voices, we also babble back. When cats miaow, we miaow back. Same with kittens', "In animals and babies, the words you use can't always be understood. Wha... |
Why can you not see deleted comments with a permalink, but you can see deleted threads with one? | Threads tend to be deleted because they break some subreddit rule . Comments tend to get deleted because they break Reddit rules . Of course, either can be removed for the other reason. |

How does electrical grounding work for ships? Why is it so complicated? | It's not about electrical safety directly. If you use a metal hull as ground, especially in salt water, electrolysis can cause corrosion. |
Why does 2008 still feel like a couple of years ago? | Probably because with each year that goes by, you have a longer frame of reference to what time feels like? I don't think I phrased that well, but what I mean is that if you are 5, one year is 20% of your entire existence. If you are 50, one year is 2% of your life. So, to get the same feeling of "long ago", it takes m... |
What makes humans want to kiss one another? | > A person receives information about the person he or she is smooching by locking lips, Fisher said. A kiss transmits smells, tastes, sound and tactile signals that all affect how the individuals perceive each other and, ultimately, whether they will want to kiss again. > Women tend to be attracted to male partners wi... |
How penny bidding sites (like QuiBids or Beezid) make their money? | As far as I know, QuiBids charges $0.60 a bid. So if they see something for $10, that's 1000 bids, and they've made $610. The person buying it gets a pretty good deal and everyone else who bid is screwed. |
Difference between Special and General Relativity | I'll explain the difference between them, without going into what either form of Relativity actually *is*: Special Relativity only deals with objects moving at constant speed. General Relativity extends Special Relativity, by figuring out how to deal with acceleration. Special Relativity doesn't actually require compli... |
How are people colourblind? | Inside your eye are 3 different kinds of cells for detecting colors, one can see red, one can see green, and one can see blue. In colorblind individuals, one of those is either missing or not functioning properly, and so the number of combinations of colors you can distinguish is drastically lowered. You can still tell... |
How does Southern and Northern US Border control work? | What's getting left out is where the border guards ask to see your passport, ask what you're bringing in to the country, and so on. |
Why do the front wheels of big trucks have such big convex hubcaps and lugnuts? | The commonality across all those big trucks having a doubled rear wheel. On a doubled wheel, you need to be able to bolt the two wheels together to be secure them. The rims budge out so they can touch each other. & nbsp; The front wheel can't be doubled because it would interfere with steering. In order to only need on... |
What exactly is a G.E.D. and why do people keep making fun of people who take the test? | The GED is the "General Educational Development" test. It is the test that those who drop out of high school, or who fail out of high school take to show that they have learned the equivalent of a high school education. They are made fun of because they have already proven themselves failures by societal standards just... |
Why is my original iPad completely useless after only a few years of ownership? | Because the software it's running is made for newer-gen models. > Is my new iPad going to do this in a couple years? Eventually, but not for much longer. The newer-gen models are magnitudes faster and more powerful than the first gen. |
How does "artificial flavoring" work, and create something so distinct as grape or other fruits? | It's all chemistry. You start with a real grape and you sit down in the lab and try to figure out what it is in a grape that makes it \'grape like\' in flavor. You could physically break down the grape into a slurry, and then use mechanical processes like centrifuges, or chemical processes like solvents and acids to se... |
Is there any way the U.N. can hit back at Russia diplomatically? | Nope, Russia could just veto it since they are on the security council. It's a fundamentally broken system. |
How are wells built? | Wells are not technically built, they are drilled. In reference to a water well, a company will do some research to see if they can drill a well in the desired area. This all depends on location, ground type, and various other things. If a well is drillable they will bring out a truck, that is basically a small oil der... |
What makes raindrops large sometimes but small other times? And is the size of raindrops indicative of how much longer the rain will fall? | Raindrops form when water vapour in the atmosphere clusters around microscopic solid particles in a process called nucleation. Nucleation is reversible. As water molecules attach themselves to cluster, other molecules are leaving. There is a point called the *critical nuclear size*, at which point the cluster of water ... |
Why aren't we concerned with bacteria, viruses, and other microorganisms developing resistance to alcohol, chlorine, and other substances used to sterilize medical equipment (and hands)? | It is a good question. The answer is how it works on the organism. Anti-biotics work by interfering with some important function of a bacteria cell. Think of throwing a wrench into a machine and watching it gum up the works. Cells that have different machine arrangements can be more resistant to wrenches. They'll have ... |
How do we 'die'? | * To kill by breaking someone's neck you need to sever the spinal cord, thus breaking the link between the brain and the rest of the body thus stopping the beating of your heart and lung function* Blood carries the necessary oxygen to the cells in your body so a major blood loss can stop your cells from functioning, an... |
How did the commonality of "seeing the light" originate when people are "crossing over" or passing away? | When your brain is deprived of oxygen , your brain shuts down different parts of itself in a given order, in an attempt to keep you alive as long as possible. Turns out, when the visual centers of the brain begin losing oxygen, you start getting tunnel vision, plus you lose the ability to see color, which means whateve... |
Brainwaves. What are they? And can sounds of certain frequencies have an effect on them ? If so , why? | What do you mean when you say brain waves? If you are thinking of the readouts of machines like EEG's or similar devices what you're seeing on these machines is the electrical activity of certain areas of the brain that are picked up by the electrodes of the machine. Because most brain activity is a chemical exchange b... |
why is the holocaust so much more popular than other historical genocides? | Aside from having one of the highest death tolls , it receives attention partly because it was a new type of event. The word 'genocide' itself was only coined in 1944 to try and name what the Nazis had done. The Holocaust was a planned, deliberate attempt to completely wipe a race of people from the Earth, domestically... |
Why does my stationary leg hurt when I ride a skateboard? | More to the point, it is almost like doing a one legged squat. In addition to holding all your weight up, you are lowering yourself several inches each time you kick/push with the other leg. I have a adult sized kick scooter where I experience the same thing. I could kick all day, but switch legs often because of the f... |
What is the significance of the MPAA joining the W3C? | The World Wide Web Consortium defines the specifications of the web.

If you're a creditor, then you can experience one or more of the following... |
Why are textbooks so expensive? | Because only a small number are printed. If you print a million of something, the costs are divided across that large number and it can be cheaper. Print only 10,000 and the "fixed" costs are now divided across 1/100 the number of books. |
Why is it when a show or movie has subtitles, we can’t help but read them? | Two things 1. Remember how you spent the first several years of your life sitting in rooms reading stuff all day? and then you go to work and read stuff all day?, etc, etc. Your brain does - so when it sees words, even without you telling it to, it goes "ooh, I know what to do here" and reads them. The brain just gets ... |
Why do we have to pay for internet? And why is there a limit? | You're not paying for "the internet". You're paying for a company to *connect* you to the internet.

They're not going to let you use those for freeThe Internet is a network. We say that nob... |
What and how can start a natural bushfire? | Lighting mainly. When a volcano is conveniently located that will suffice. Plus if you have a decent damp pile of plant matter as it decays it can just get hot enough to burn.There are plenty of hot things in nature. Lightning being the main culprit. The Australian bush is designed to burn. That how it germinates. Dry ... |
Why must we let a steak "rest" for best flavor, but that just makes it cold? | You just need to let it rest for 5-10 minutes before cutting into it. When you cut it right away after removing from heat, you will notice the plate will fill with liquid. That liquid is full of flavor that the steak losesYou aren't supposed to wait until it's cold. Heating the meat makes the proteins "tense" up, thus ... |
Why can you hear the voices in the apartment above you so easily, but not the voices in the apartment below you? | Because sound travels through the solid medium . On the floor above, people are directly in contact with the surface; while on the floor below, you're only depending on the noise traveling through air and noise traveling in air is divided into reflected, absorbed and transferred, major percentage of which, is reflected... |
How comes different phone chargers take widely different time to charge the same phone,despite all being rated 5V 1A? | The usb standard originally allowed for only 500mA to be drawn per port. This isn't really enough for smartphones and especially power hungry tablets etc., so the manufacturers came up with a way for chargers to indicate they were willing to supply more power to the device. The device charging circuit can then draw mor... |
Why is mace (pepper spray) illegal in the UK? | There is no such concept as "defensive weapon" in any of the UK legal systems.

What is the force that causes you to think of someone moments before they call or text you? | Coincidence, confirmation bias and faulty memory. There are no special forces. Rather, sometimes when you happen to think of someone they will contact you soon after. More frequently when you happen to think of someone, they won't contact you at all. Human memories are fairly flawed. Some of us might think we are maste... |
Why does the U.S. military use exciting action commercials and other fanfare for recruiting rather than just telling us what the threat is? | Why does Bud Light have commercials of a guy playing ping-pong with Arnold Schwarzenegger instead of advertising its price and alcoholic content? Like any other advertiser, the Army spends millions trying to find the best way to sell themselves. The simplest answer is likely the exciting action commercials are the resu... |
What are the differences between the North and the South Pole? | The North Pole is in the middle of the water, usually covered by ice , and has polar bears, but no penguins.

What exactly makes some genes dominant and others recessive? | I remember that this was explained on Ask Science a year ago ; here's the link to the answer given, as it's really nice: _URL_0_ To paraphrase the analogy: Genes code for different things. Some genes code for different structural proteins. You can think of these genes as coding for bricks. Our "good" alleles code for r... |
How a recession causes lower gas prices. | Gas prices are largely driven by gas demand. The *demand* for gas however isn't usually driven by prices. That is, most people don't travel less just because gas costs more, they have a set number of miles they *have to* travel to live their lives. Well, if a bunch of people don't have jobs, and don't have any reason t... |
Why trees produce different shapes/sizes of leaves. | A thing to remember about evolution is that so long as a trait works well enough, and doesn't kill an organism or weaken it to the point of applying direct evolutionary pressure, it will remain. Leaves are a balance between energy expenditure and energy production. Trial and error from mutation and different plant bran... |
The five lesser-known types of magnetism? | Basically, magnetic fields happen because electrons have small magnetic fields. There are various ways they can prefer to behave in a material, giving rise to their magnetic properties. Diamagnetism is most noticeable when there are no unpaired electrons in a material. This negates the magnetic moment of the electrons ... |
How does my cat know to look at my eyes/face when communicating something? | It's been a common thing for workers in parts of the world to have to wear face masks on the back of their head because tigers won't attack if they think a person is looking at them. So this goes past domestication and is a hunter instinct. _URL_0_ And just as a tip for owning cats, look them int he eyes every now and ... |
OJ and the recently discovered knife can we still prosecute him or no since double jeopardy? | Without considering the Double Jeopardy, the knife was supposedly found years ago and kept by as a souvenir by a cop. It was only recently brought forward as evidence. Pure speculation, but it could be real hard to use it as evidence in court since it was handled improperly. Edit: improperly', "We couldn't prosecute hi... |
Why do the body-cells age? | A few reasons. The most straightforward is that every time a cell copies it's DNA, it uses up a piece of the tail at the end of the DNA called the *telomere*. When a cell is out of telomere, fragments of the DNA itself start getting used and the cell goes into *telomere panic*. Each copy does damage to the DNA after th... |
What is involved in porting a PS2 game like Metal Gear Solid 2 to Xbox 360/PS3 for an HD Collection? | PS2 and X360/PS3 have different processor architectures. Which means that the same piece of code means different things to those machines. That's where emulators come in. An emulator is a software that reads a code that's written for a certain processor and "translates" it to work on another processor. Now to make an e... |
Why does the water spray from the shower feel cold when you're standing next to the beam itself, even if the water is warm? | I believe you are feeling tiny borderline microscopic droplets of water which due to their size lose their heat to the environment extremely quickly |
why do empty folders contain 0 bytes of data? Don't folder names contain (even a few) bytes of data? | The contents of the folders are 0 bytes of data . It's like saying a real-life box contains 0 pounds. But the box itself isn't 0 pounds. |
Do caterpillars know they they are going to become butterflies? Or do they just get in a cocoon thinking, what the fuck am I doing? | You're giving them too much credit. When you get to insects that small, and insects in general, scientist aren't even sure they're capable of abstract thought like that, they're closer to biological machine, who just do what they do on instinct alone, their brains aren't really complicated enough to make it seem credib... |
What exactly causes Mouth ulcers? | Most are caused by unintentional damage such as biting. Recurring ones can be a sign of an underlying health issue. This may help_URL_0_ |
Why does food (meat, cheese, bread, vegetables) taste different when sliced thin vs thick? | I would guess it's because there's a greater surface area to volume ratio, so comparatively more of the food gets exposed to the air.

Part of the settlement was that the tobacco companies had to fund the [American Legacy Founda... |
Why is the camera on the Mars rover so low quality? | We can, just not yet. These cameras are the initial landing cameras to make sure it survived the landing. Later this week, the fancy dancey cameras will spring up and give us lovely, awesome imagery. Although it's pretty awesome already in my opinion :) |
Expiration dates for painkillers (details inside) | You are looking at date Filled vs date expired. Not date manufactured vs date expired. These drugs are created in large quantities but that doesnt mean they all get distributed at the same time. So the ones you got in 2013 and the ones you got in 2015 could have all been made in 2013. Drugs do expireAlso, expiration da... |
How do pearls form? | Here's a hint- It's the same material as their shell. The sand is an irritant to the soft gooey creature, it can't reach to dislodge a grain of sand that is stuck, so it covers it in a layer of the same stuff the shell is made of. They get the minerals from their diet. Layer after layer it gets incrementally larger, ju... |
What happens when you charge a battery | Batteries make electricity when chemicals inside of the battery undergo a chemical reaction. Chemical A combines with chemical B to make chemical C + electricity. When chemical A and chemical B run out, the reaction has to stop. In chemistry, every reaction is reversible. If A + B make C + electricity, then C + electri... |
why are there only ever 2 or 3 NFL games available on tv each Sunday, instead of 5-10 like for college games? | > many games available on standard cable packages like college? Because they make more money the way it is currently setup. It's pretty simple at that. They have limited games on broadcast TV which they charge crazy rates for, which in turn is a limited amount of games people can watch which means everyone is watching ... |
How come old people sound "old". I'm not sure how else to explain it but they just sound different and harder to understand? | The cartilages in the vocal tract calcify and stiffen and the muscles get weaker. It makes their voice breathier and makes it more difficult to keep the pitch and loudness steady.In addition to /u/Holyrush's comment, it could be due to accent differences amongst generations. |
Why do Humans (and most mammals) have individual teeth instead of a beak or solid bony structure? | Only reason I can think of is, if one of em breaks, we can still chew', "We can really only speculate since evolution has decided this is the best thing for us. Individual teeth have some advantages though with the main one being specialization. We have teeth both for tearing foods and grinding while birds and such don... |
Why do people look away from the point of focus to think? | If you look away there's no stimuli trying to get your attention. You can look at a blank wall and not have anything stimulating you while you search your head for the answer. |

Smoking was banned on planes in the US in 1988, 24 years ago.Because if someone were to light up a cigarette they still need a safe place to put it out. There is way too much paper waste in the trash cans that could potentially start a fire in flight were a butt to ... |
How come humans generally get into cold water slowly and uncomfortably, but animals jump in with no hesitation? | If you think animals are not afraid of water you have never tried to bath a horse or take one through a puddle. lol.
