if we say an atomic clock is wrong 1 second for every 1 000 000 years, have we actually a better way of measuring time? | Yes, two atom clocks. You do not know which one is right but it gives you an indication of how accurate they areNot necessarily. But if you put ten atomic clocks in a room and come back and check them a year later, you can see if they have drifted apart, and use that to estimate their accuracy over longer periods of ti... |
Can someone explain me how electronic component get old? | One reason is due to [electromigration]. The diffuse metal atoms in various components in a computer experience a momentum transfer with the electrons that gradually cause electrical shorts to form on a nanoscopic level. Another more immediate reason would be the electrolytic capacitors that are commonly found in compo... |
Legality of using real life people in fictional stories | Famous people can and often do copyright their own image and likeness in order to prevent this from happening, and for people who have done so you must go through their estate even after death. Lincoln never did this, and neither did most of the long dead famous people you see on TV. |
Why is it that when its dark, stationary things look like they're moving? | The center of your retina is missing the cones that process low-light, giving you a nighttime blind spot, directly ahead.

Why do countries dispute uninhabited, useless territory? | Islands are great to own, because they give you ownership of all the water around them for many kilometers, including all the fish, oil, or whatever else might be down there. Mountains are great to own, because they provide military defenses, and because they often contain minerals you can mine. I don't know what cural... |
in baseball, Joe DiMaggio's hitting streak of 56 consecutive games is one of the most notable records in the sport and is considered "unbreakable." Why is this? | The trick is that hits are hard to get and that even great hitters don't get hits that often. It's easier to understand with an example. So, let's say that a person is batting .400---meaning they get a hit four times every 10 at bats. being a .400 or above hitter is all-time best level hitting, so we're already talking... |
How do sewer systems and, afterwards, water treatment facilities work, from the moment I flush the toilet? | it really depends on where you are, what is your legislation and the kind of treatments. Anyway usually toilet flushes got collected and goes into treatment facilities which try to "clean" the water. * floating objects and big debries are removed with grids * most of the oils are removed * bacteria are used so that nit... |
Why does water cause electronic devices (I.e. cellphones) to malfunction even after said devices have completely dried? | Unless it's distilled water, water is actually pretty dirty. It's full of little particles and sediment. Take a really close look at a glass of unfiltered drinking water and you might probably see some. Anyway, when a device gets wet those particles settle on the microchips shorting out some of the connections . That's... |
How does air humidity percentage work and how are we still able to breathe when it's 100%? | 100% relative humidity means the air has as much moisture as its temperature allows . This means if you sweat, it won't be able to evaporate since the air is fully saturated with water vapor. So you will feel much warmer, since you're not able to easily lose body heat. It doesn't mean that the air is 100% water. |
Why are vision problems more common than problems of other senses (ie. hearing, smell, etc.) | Eyes require their exact shape to work. Vision is done by a reciever that needs a focused light on it. That light comes from the front of the eye and gets put through the lens, which can be adjusted, and the iris Contrast that to an ear or the nose or touch. Hearing, smell, and touch are all 'fixed' things, for the mos... |

What does an Apple computer do better then a (Windows) PC? | Mac owner here: Nothing, really. That being said, I like the fact that I don't need to deal with drivers, have a nice GUI on top of UNIX , and I can still boot into windows to play those "Windows Only" games.Back in the day, Macs were a lot better for things like video editing, sound recording, film production, graphic... |
What is the difference between men's and women's razors? | Good question! The biggest difference is the angle of the blades themselves.

The downside to a more aggressive angle, though, is a higher tendency for razor burn and cuts if you've n... |
What is wire fraud in the US? | Any crime in which the defendant voluntarily and intentionally devised or participated in a scheme to defraud another out of money; the defendant did so with the intent to defraud; it was reasonably foreseeable that interstate wire communications would be used; and interstate wire communications were in fact used.*Frau... |
When film earnings are being calculated, especially big releases that break all sorts of "biggest opening weekend" and such, is inflation taken into account when comparing these numbers to older films? | The only reason that films keep breaking records all the time is because ticket prices have been going up over the last few decades. If you look at how many people went to see 'Gone With The Wind', you'll see newer films won't come close to selling that many tickets, even though they make more money. BoxOfficeMojo esti... |
Why does food taste so much better when you’re drunk/high? | So I don't have the exact science but basically when you're high, everything that you like the taste of becomes even better tasting. Additionally, the THC interacts with brain chemistry so that you can't feel as full. Add this to the fact that if you're smoking , you have dry mouth. Eating/drinking is very satisfying. ... |
Why do the Japanese care about blood groups? | There was an Japanese person who wrote a best-selling book in the 1920s or 30s on personality being determined by blood group. They were successful in convincing people it was scientific, since it was based on a biological testable characteristic. In other words, the writer made it seem like a scientific fact, even tho... |
Why is size of an animal such a good estimate of its strength, but size of a brain is not a good estimate of intelligence? | The answer by /u/Doktor_Wunderbar is a good one , but it misses out a critical factor - the EQ _URL_0_ At a simple level, this says "based on what you look like, your brain should be about this big. How big is it really?". So as a general rule, bigger animals have bigger brains. Lots of reasons for this, but as a basic... |
Why can't telescopes work like magnifying glasses? | Microscopes and magnifying glasses take light from a small area and spread it out. Telescopes take light from a wide area and bring it together. |
Why is that even though I've been waking up early for school for years at pretty much the exact same time, my body is always tired and never seems to get used to it. | There's more than one reason this happens, I'll try to explain 2 of the most important/accepted ones. 1.

why are people with autism/asperger's sensitive to various environments. | Because autism is a processing disorder. It means we process things, everything, differently from other people. Either more, or less, but usually more. You see a bright like and your brain processes it as a bright light. We see a bright light and our brain doesn't know how to process it, so it processes it as thid huge... |
Black holes suck in light, so why are they black? | We call them black because we believe that they suck in light and don't let it out. It's outgoing light we can see, you can't see light that's being absorbed only light that is being sent out or reflected.Black is the label we apply to an absence of light. You can't make a flashlight that projects black. Since the BH a... |
Why does it seem that no one "drops dead" from cancer? | Cancer doesn't grow that suddenly.

But my girlfriends grandmother slipped one day. Her spine completely dislocated because a cancer had eaten ... |
If something were to break the sound barrier in space, how would it differ from here on earth? | The speed of sound depends on several variables even here on earth - humidity, air pressure, etc. Thus there is no "speed of sound" anywhere sound can't travel, such as in space.There is no sound barrier in space - because it means the speed of sound in air and there's no air for there to be a speed of sound in. That s... |
when I drink water, does my body still try to digest it as if it were food? | Yes and no. It goes down the same path and is absorbed in a similar way. But your body doesn't "try" things on various chemicals ingested, it just sort of happens when exposed.Water goes through your digestive tract with the food. Whereas food is digested and vitamins/nutrients are absorbed in the small intestine, wate... |
why do some people love food that other people find disgusting? | Humans may have the same types of taste buds but the concentrations of taste buds may differ. For example, [supertasters] have a very high concentration of a certain taste bud so they experience very strong reactions to specific tastes. Furthermore, these taste buds are connected to our brain which may reinterpret the ... |
Why is that military personnel can't open fire against anyone until they have been fired upon or lethal threats are obvious but US police officers can pretty much shoot at will? | I can't answer this with certainty, but I think it is just the fact that the Military personal are extremely well trained, police are not.

Why does being Hispanic categorize you so differently? | Your ethnicity can have an affect on what diseases you are more or less susceptible to or likely to have. |
Why is ocean water naturally salty while lake and river water is relatively pure? | River water is, generally speaking, rain. Oceans, on the other hand are places where salt can collect. Basically, water falls from the sky, runs over/through the ground, and ends up flooding the lowest possible area, which becomes the river. The water in the clouds starts basically pure---since it's evaporated water---... |
why is there a lag after putting my hands in scalding water before the pain registers? | I'm not really sure what you mean by that -- I feel both in what seems to be the same time. But I'll see if I can do an explanation: A cut severs part of the nerves, causing an immediate chemical reaction that triggers the electrical impulses which inform the brain. Heat has to transfer through the layers of skin , get... |
Why do we still use steel if many synthetic materials claim to be X times stronger than steel | When you talk about strength of a material from an engineering perspective, there are many different types that are used. You have tensile and compressive strengths, and things like strength to weight ratio, which most people have heard of. But you also have definitions like yield, ultimate, and fracture strengths. On ... |
What makes pee burn when you're dehydrated? | Uh, that's not normal. You might want to go talk to a doctor if it burns when you pee. Good luck with that and remember, "No glove, no love."', "Pee is your body getting rid of toxins that dissolve in water.

Why is the US in so much debt, and what caused it to be so high? | Basically, there are two streams of cash: coming in and going out. What comes in is taxes. The government collects taxes every year to pay for the things it wants/needs to do. What goes out is spending. Every year , Congress passes a law that lays out exactly what is going to be spent on what, and it's called the budge... |
How do they release HD movies that were out decades ago? | Because the film originally used had higher resolution than the standard HD formats anyway. Quality 35mm film has a horizontal resolution of approximately [4096 pixels], which is about twice the resolution of the [1080i/1080p] HD format.Imagine getting a VHS quality video, then expanding it to the size of a cinema scre... |
Neural Net "dreams" | They are using a very large neural network model that was used to classify images into categories.Its probably a convolutional neural net which looks for small features in the image by "scanning" it.These learned features are pretty much stored inside the neural network. which it sees them those neurons fire producing ... |
Why are added sugars so much worse than natural sugars? | > Wouldn't it be just as bad to eat an excess amount of natural sugars? Yes. Eating an excess amount of anything can be bad for you. There is nothing inherently "worse" about eating something that has added sugar instead of natural sugar. So long as you are eating the right amount for your body, it will be good for you... |
Difference between 32bit and 64bit | Think a 4 lane highway vs an 8 lane highway . The cars are the information. The amount of lanes does not effect the speed of the cars. Picture 8 cars going down each highway. 8 cars on a 4 lane highway, the car will have to go in two rows of 4. The second row will get there after the first row. 8 cars on an 8 lane high... |
If I got a lot of extra sleep last night, and very little sleep tonight, will that balance out and leave me well rested on Saturday? | Your body does best with a consistant amount of rest. The extra sleep will likely help get through the long night, but it is unlikely that you'll wake up feeling well rested.No. Sleep is a bit like charging a battery. You can do it until you're fully rested, but sleeping longer won't let you "overcharge". |
If binary is a deterministic process how are computers able to so randomized operations/calculations? | Usually they're *pseudo-*random number generators. They're actually deterministic, but they're random enough for most purposes. Typically the process is seeded with something like the current time so that the deterministic process starts from a different place each time and you don't get exactly the same results every ... |
What exactly is REALLY going on in the American political scene right now? | We have a controversial president. He didn't win the popular vote but because he won the right states to win, he beat his opponent. Some argue that he's crass, sexist, and racist and doesn't know what he's doing. Some argue that he's incredibly smart. Some argue that he won because of Russian hacking. Some argue that h... |
Why our bodies are more sensitive to wind when we are wet. | We sweat to release heat from our body. Sweat evaporating takes heat with it. When we are wet, the water is taking heat from our body, too. As it evaporates, it cools us down. Wind removes heat as well, as it is almost always colder than our body. Wind plus water just removes far more heat than either alone. If you wer... |
Why can't I use my Canadian passport in America when I have dual American-Canadian citizenship? | Most countries don't recognize dual citizenship. They don't outright ban it, but they don't care what other countries think first and foremost, you are their citizen. So to the US, you are an American, how Canada feels about you is irrelevant. Americans must enter the US with a US passport. It is probably true they jus... |
Why does it take Android OEMs so long to get new versions of Android to their phones? | One of the biggest parts of it is that every phone has a slightly different kernel . Yes, it's all Android, but the specifics are tailored to that specific phone's hardware. If you took the version of Android running on your Galaxy S5 and tried to run it on my Nexus 4, for example, it wouldn't work. That's why every de... |
Why can't we dispose of nuclear waste by putting on a subduction tectonic plate to sink it into the earth's core? | It would work. But the subduction plates move at the same rate that your toenails grow, or thereabouts. So it would take years and years and years for the waste to disappear. Years that highly radioactive/toxic material is sitting on the ocean floor, polluting the water and killing nearby organisms. Not to mention the ... |
Why are foods associated with times of the day? | Not scientific at all, just a possible observation. Imagine it's 1910. You don't own a refrigerator. When you wake up in the morning, what seems fastest? Going out to get eggs from the chicken coop, milking a cow, and eating some leftover bread . Slaughtering a chicken, defeathering said chicken then roasting the chick... |
- Why do I see green patterns of flashing light when I press in my closed eyes? | Basically you can stimulate photoreceptors in the eye with pressure, as opposed to light. The stimulation causes you to see something, in this case a green flashing light pattern. |
How does a Tesla vehicle "see" the car AHEAD OF the car in front of it? | > Taking this one step further, a Tesla will also be able to bounce the radar signal under a vehicle in front - using the radar pulse signature and photon time of flight to distinguish the signal - and still brake even when trailing a car that is opaque to both vision and radar. source: _URL_0_ |
Why the Xbox One included what was used in 4Chan's latest exploit | This particular set of instructions is not a single feature of the Xbox One, but the linking of a couple of features together to prouce an undesired outcome. Access to a developer console is rather common and whether they intended to leave this access in the shipped product is unclear to me. It can be useful to have lo... |
How am I able to make it home safely after being blackout drunk? | As your car gets older, you can expect certain things to stop working, but you don't know the order in which they'll stop working. If you car's brakes stop working, that's bad, you're not going anywhere. But if your headlights stop working, it's not going to prevent you from getting home. Being blackout drunk means the... |
Why do eyes sometimes change color depending on the day/time of day? | Eyes do not change color, outside of a slower change as a result of certain diseases. The differences you see are caused by varying light levels, angles, etc. The same way a shirt can seem blue in one light and green in another. |
Difference between United Kingdom, Britain and England | So if you look at [this map], you will see that England is pink, Scotland is blue, Wales is red, Northern Ireland is yellow, and the Republic of Ireland is green.

Why do we "run out" of laughter after a laughing fit? | I don't understand why every person in this sub assumes that everyone experiences exactly what they do. I have no idea wtf you are even talking about here. |
How did they do those human transformations at the end of Michael Jackson's 'Black or White' music video? | They used "[Morphing]" software to take 2 images, plotted out the similar parts of each and blended them from one to the other. |
Why, when baking, do you have to add different ingredients at different times, using different techniques? | Cooking is just science that makes you poop.Well, for instance, butter is a solid at room temperature. If you were stirring a bowl of room temperature batter and just dumped melted butter in it, it might form clumps as it re-solidifies, so you pour it slowly while stirring so it mixes evenly in. With wet and dry ingred... |
How radiation and radiation poisoning work? | depends on the exact type of radiation. there are two types, particle and electromagnetic. bit cause problems by breaking apart molecules in our cells, but how they do this is a bit different. Electromagnetic radiation, which is photons/waves of energy, imparts energy into molecules when it hits them. this makes the mo... |
What is the Purpose of the Pad Part of a Water Lily? | Since it's a plant, it needs to get energy from the sun to live . It's easier to do this on the surface than underwater, especially in murky waters like are often found in ponds and lakes.The flower of a water lily is for mating, trading pollen with other lilies, and eventually forming a seed. The pad part is the leaf,... |
Why have the majority of men in recent history preferred shorter hair then women? | Hair that is very short cannot be grabbed in battle, so that's why the military uses short hair, traditionally. You might be surprised how much influence the military has on fashion. I believe the modern business suit is a reflection of officer uniforms. |
What causes the "dry spot" in your throat? | If you feel like just one spot is dry, this is an illusion -- it's actually irritated, not dry. This can be caused by a persistent drip of mucus from your sinuses into your throat, or by a throat infection. |
Why do bugs seem to fly in circles around one when out hiking, particularly around the head? | Generally, they are either attracted to the carbon dioxide you are exhaling or the body heat you are giving off. For flies, it's the CO2, mosquitoes seek body heat. And the head is usually the hottest part of your body, and it's usually exposed, especially in the type of weather that mosquitoes are an issue. |
Why do YouTube comments' dislike button exist? What does it do? | It does literally nothing. In fact, if you dislike a comment then hit f5 and it won't even show that you hit the dislike button. |
Why do people post questions here that could easily be googled? | Because googling it wouldn't get you an answer that is dumbed down and simplistic. It also wouldn't give you the opportunity to ask follow-up questions of the answerer if you still don't understand the concept. |
What is a "non-member observer state", and what does this mean for Palestinians? | Its a half-way step to becoming a full-blown member of the UN. It is recognized as an official country , which means they get to send a representative to sit in and listen to the goings-on in the UN , but not cast any votes . |
How do they take crystal clear pictures of jets going supersonic speeds? | Two methods in combination: very fast shutter speeds, like 1/1000 of a second or less -- I've taken pictures of helicopters this way where it doesn't look like the rotors are moving. Also, follow along with the plane as it moves. Any background trees or whatever will probably end up blurry, but the plane will be sharp.... |
(Serious) The thought process that leads doctors to choose to become proctologists, gynecologists or urologists. | I can think of three reason: 1) Money - If these positions pay more money, doctors will follow. 2) Demand - Perhaps a lot of doctors do not want want to be urologists and such. However, since fewer doctors take these jobs, these positions will more available. So the doctor has the choice to compete against 100 other do... |
I don't have a lisp speech impediment but can mimic one if I try, why can't someone that has a lisp speech impediment do the same in regards to speaking without one? | Sometimes, the lisp is the result of the shape of the mouth and teeth. In such a case, you may as well say "I don't need a wheelchair, but I can still use one. Why can't disabled people just walk?" Often, though, it's psychological, and can be trained away by a speech therapist. That's why lisps are more common in chil... |
how gas planets form differently than terrestrial planets | Two major theories: 1: They form much like rocky planets and infact have a rock or ice core. Basically they just form earlier when there's more gas in the disk around teh star. 2: They form kinda like stars in that you get clumps of denser gas in places which can pull more gas toward itself and so on. They just form la... |
How does Walmart justify its employees costing taxpayers $6+ Billion in government assistance a year? How (why) do they get away with it? | Why does Walmart in particular need to be held responsible for the government assistance its employees use? Is Walmart is inherently more evil because they pay people similar wages/benefits as other retail stores simply because they're larger? What about food service giants or other industries which predominantly keep ... |
How the fuck do I keep coriander/cilantro alive? | Give it deep soil, water enough to just keep 1"down damp. DO NOT overwater and give at least 5-8 hours of sun each day. Anything above 20° 60° is warm enough. |
Why do some fermented drinks need yeast, and some other drinks need yeast and bacteria (scoby)? | Fermentation with yeast and without bacteria is alcoholic fermentation, with bacteria lacto fermentation. Kombucha isn't intended to be an alcoholic drink, although it does contain some alcohol.But if you want an alcoholic drink you would use yeast and not a scoby to ferment the sugar water. If you want a drink with pr... |
How much did the recent deluge in SoCal help the drought? | Helps a little short term, but yeah, it needs to be in the mountains and **a lot** more than what we just got. The ocean is pretty gross right now, for what it's worth. I wouldn't swim for a few days at least.From my understanding snow pack is what we need. Rain like this dosnt really do much except cause mud slides, f... |
Why aren't more laws created or changed by grandfathering them in years or even decades from now? | Because a grandfathered in law can still be changed before it goes into effect. Sure, *now* it won't hit hard, but in 10 years when it's about to happen? People in Congress *then* are going to be de-elected if it actually goes into effect. So, they'll put it off, or scrap it. Besides that, setting a policy to happen in... |
Lewy Bodies and Parkinson’s Disease | Basically, there's this region in the brain called *substantia nigra pars compacta*. This region is rich in dopaminergic neurons and is, roughly speaking, responsible for fine motor movement. Parkinson's disease happens when dopaminergic neurons on this part of the brain begin to commit apoptosis . Lewy bodies are prot... |
Why do bees die when they lose their stingers? | Most bees will never reproduce, so sacrificing their lives for the colony does not effect the evolution. When a stinger is left in its victim it causes greater pain and incentive to stay away from the colony, effecting the evolution.They die because the stinger is barbed and sticks into the skin and doesn't come out, a... |
How does my car radio pick up digital details (station, artist, song) on just FM reception? | The FM signal actually contains different parts separated from eachother and one of those is the [RDS or Radio Data System] used to send program information. [Here] is an illustration of different parts of a FM signal. The green to the left if the mono signal, after that comes the pilot tone that tells the reciever it ... |
If we (the human race) somehow become immortal, aren't we basically dooming ourselves? | If we were to become immortal, there wouldn't be a need to adapt. If the end game of evolution is to create something that is able to survive as long as possible, then immortality would be the endgame. |
why does hearing and balance happen in the same organ? | Evolution often creates the simplest system that works the most efficiently. In order to hear, your body has a complex series of physical reactions that happen in your ear transcribing sound waves. The last stage of this transcription, which converts the sound wave messages into neural signals, takes place in fluid-fil... |
Why are domestic or shorthaul flights in the USA/Canada so much more expensive that comparable distance air travel in Europe? | A main reason: more competition not only by other airlines but also trains, as Europe has a resonabley fine rail network including highspeed trains between mayor centers. Also you have to be carefull with airfare quotes as they often do not include various fees.It actually has a lot to do with Airport taxes, and Nav Ca... |
How do animators match up the characters' mouths with the voice actors' words? | They record the voices first, almost always. They time out the syllables by listening to the audio, and figuring out when each syllable hits what frame in the timeline.
