In the aggregate, as in mashed up with everybody else's data, it's just demographics and it doesn't matter much. But in the specific it could be worth your life. So let's say I'm your stalker, if I can prise your specific data out of the aggregate then I can shadow your life. Let's say I'm the malicious ex of your curr... |
In the early days of the automobile manufacturers did sell directly to the consumer. Then automobile sales began to boom. Manufacturers didn't have the capital to create enough dealerships to sell all their cars in every city across the nation so they franchised out to dealerships. This helped car manufacturers reach c... |
Because your browser still doesn't know how big that image is going to be until it downloads it, so it has no way of knowing how much space to leave. The people who design the website could plan for it, but many of them don't. |
Singing uses a slightly different part of the brain than normal speech. As such it can bypass the causes of some kinds of stuttering. But it will not bypass all causes so some people do stutter when they try and sing. |
Most probably this happens due to having low blood pressure. Hot water (heat in general actually) raises your body temperature and then our termoregulation mechanics kick in. One of that mechanism is to vasodilate our arteries in order to widen the contact of the artery with the surface of the skin in order to lose som... |
Because no real phone number start with that prefix. This means shows can use a number without accidentally giving out a real person's number - 8675309. Fun fact, there are valid 555 numbers. For example, area code+555+4141 will get you 411 in that area code. How do I know this? I run a call center auto dialer. Someone... |
Basically most living creatures involve proteins, once you raise proteins over 40 degrees C they start to denature (break apart) therefore they tend to die, this includes bacteria. So whilst boiling water won't remove dirt it will kill disease causing bacteria. You're not boiling water to clean out dirt, you're boiling... |
That is definitely not true. In *most* cases it is true, but viruses come with single stranded DNA, double stranded RNA, double stranded DNA, and single stranded RNA. Then again viruses aren't organisms, so depending on definition all organisms might have double stranded DNA and single stranded RNA. I'm not sure about ... |
The Ringo thing is largely a joke. He's a pretty decent, innovative drummer. The drums for Come Together for example, are quite distinctive. This video explains it well: URL_0 As for Meg White, she's just a bare bones drummer, not bad as such, but just not particularly innovative or memorable. I guess her playing style... |
They use alternating current to magnetize the sorting magnet. If you use permanent magnet then aluminium will not be attracted to it, but if you put aluminium in magnetic field that constantly changes direction this magnetic field will generate electric curent inside the aluminium. When electric curent flows trough met... |
Ease of design, mostly. If you stack 7 circles in as close a shape possible, you get an hexagon with 2 on top, 3 in the middle, and 2 at the bottom. Use the centre as a rotating part, and you get 6 holes in a symmetrical way, without having to do weird complicated math. It was the result of the best ratio of diameter o... |
B cells possess specific antibodies so that they only bind to one specific antigen (typically a bacteria cell). If binding occurs, the B cell engulfs the antigen and breaks it down into small pieces. Some of these small pieces, the protein ones, attached to another protein called major histocompatibility complex (MHC),... |
Elements with higher atomic numbers than iron actually use up net energy in order to fuse rather than releasing net energy. They also release energy when they break apart (fission) unlike elements with lower atomic numbers than iron (which use up energy to break apart). Iron is basically at balance - it takes up energy... |
Source: I'm a final year forensics student and currently writing a paper on fingerprints. I'm in the UK so ymmv. Depending on what you mean by 'reader' and how sure you want to be the answer varies. Fingerprints are examined on 3 levels by people and databases. The first level is the general shape (whorl, arch, etc) an... |
For me it is natural. I just seem to thrive when operating later in day/night. For many years I worked a regular job that started in the a.m. and ended in the p.m., like almost everyone else. I struggled and struggled with having to get up so early. Frequently I would end up till 2 or 3 a.m. and having to get up at 5:3... |
It might be that the idea of getting up to face a full day of stuff you don't want to do is a lot harder than just getting up to eat cereal and watch cartoons I believe it has to do with the REM cycle. There are points of natural lighter and heavier sleep and an alarm can interrupt a heavier point in the cycle. With no... |
Personally I think that the creator probably chose the 10m block time so Bitcoin can run on more computers and use less bandwidth. This bandwidth is incredibly important as the currency grows, more bandwidth is needed for each update. It would also be a lot easier to mine the Bitcoin, lowering the value as more is avai... |
There's actually quite a few things going on here that can give this perception. First, a lot of plants don't take very long at all to 'perk up' by sucking the water through their roots. This causes their leaves or blades (in grass) to become plumper, and that shows off their green colour better. Second, there's a lot ... |
Remember, your brain is an unreliable narrator. Evey sensation is being filtered through your memories, your expectations, your beliefs, your present mood, and your attention before it is handed over to your conscious mind to analyze. Your brain is like a CEO with a very agressive personal assistant. Thousamds of thing... |
Its water vapor. There are imperfections in the bottom of the kettle, little bumps and spikes in the surface (microscopic), which heat up the water faster, in that particular spot, and causes it to evaporate, while the rest of the water is still mostly in liquid form. Water vapor. Fluids generally exist as liquid and g... |
The analogy I saw was that you have a tower with a light on top that is used to send messages. AM is like changing the brightness of the light to send the message. FM is like changing the color that the light is showing. Edit: changed blinking to color To understand this, first you have to understand what a radiowave i... |
Any rigid body has three axis perpendicular to each other about which the body can rotate without the need of an external force to sustain the direction of the axis. This axis are called principal axis of inertia of that body and each of this axis has a principal moment of inertia. These three principal moments of inte... |
In 1929, the US stock market crashed in what was essentially a really bad day. With multiple industries suffering (steel and agriculture in particular), investors pulled out of the market in droves and drove prices down. With the sharp drop in stock prices, many people were worried about their savings, held in banks th... |
Have you ever though about the fact that it isn't? |
It is vital to verify who these "experts" are (i.e. credentials, primary or secondary source, peer-reviewed, no biased funding, etc.). From my understanding, games do not *significantly* affect neuroplasticity. Of course, legions of secondary or 'pop-neuroscience' sources rush to write sexy headlines about very general... |
Organic agriculture is less productive ([source]( URL_0 )). Also, demand for organic is probably less *elastic* than demand for normal food. Elasticity means "how much demand decreases as price increases". Organic food [is not healthier]( URL_2 ) and it's [worse for the environment]( URL_1 ) (due to lower productivity ... |
The GPS satellites are in a medium earth orbit, so they go around the earth twice a day. Their exact locations are tracked very accurately by control stations on the ground on a regular basis, and the orbits are predictable enough to calculate where each satellite will be at any moment. The satellites send out a signal... |

A typical SSD connects directly to your c... |
So, during REM sleep it's generally believed that you are probably dreaming you just don't remember the vast majority of it). The reason your eyes are moving is that they're one of the muscle groups that aren't paralyzed during REM. If you were to measure someone's muscle activity electrically (this can be done with el... |
My local gallery has [a Jackson Pollock]( URL_0 ) on display. A small picture of it on a computer screen looks like a pointless mess of random paint. But the actual painting is eight feet by thirteen feet, and lacking the appropriate formal vocabulary all I can say is that in person it looks *very impressive*. I'm gene... |
Losing some volume due to muscles relaxing, skin drying out and loss of blood flow further contribute to the lack of "fullness" you used to see. |
Many intersections are controlled by a combination of timers and inductive sensors in the road. Each phase is generally set to have a maximum time, but the phase may be ended early or skipped entirely if there is no vehicle waiting at or moving past the sensor. |
There are two things at play here. To start with we do not every feel how fast we are going, we feel the *change* in speed. When an airplane speeds up down the runway to take off you feel yourself getting pushed back into your seat. But once it is at a steady speed you no longer feel that. The other aspect is wind. In ... |
You often don't, you're just asleep and don't notice. Trying to get a good nights sleep next to my wife if she has a cold is a nightmare. |
Steam escaping, which changes the center of balance of the potato, combined with a rounded bottom which allows it to easily rock back and forth. The question is why dont you have them in tin foil? |
How do languages begin? First answer: Languages are formed when people living in groups begin to find certain behaviors, bodily movements, or gestures as symbols. Perhaps a certain look in the eye could communicate anger or affection. That look could become a symbol and thereby may be adopted by all the members of the ... |
Anyone can make a note that's impossible to decipher. The easiest way is to just not have any actual information in it, to not actually have it contain a message. Naturally you can't decipher that. The second way to make a note, and a way that contains actual information, that cannot be deciphered is to use a "one-time... |
We eat specific types of eggs mainly because we domesticated chickens and bred them to produce a lot of eggs. Its very convenient, you just have a coop and can get all the eggs of a pretty good size that you want instead of going around looking for nests and climbing trees. For similar reasons we like to eat chickens b... |
One example: grocery shopping for the White House takes a long time. They can't order the food in bulk from a single supplier, because that would make it easy for someone to poison the president. Instead, plainclothes Secret Service staff have to go out and buy from randomly chosen grocery stores across the DC area. If... |
The yellow color is from the final breakdown product of hemoglobin in your skin, a chemical called bilirubin. It clears waste products of aged, destroyed red blood cells. |

IQ tests involve specific tasks. They're heavy on pattern recognition and comparing things, in language, numbers, and visually (shapes etc). You spot similarities, differences, and make connections between objects or concepts. The tests are also time-limited or doing them faster improves your score, IIRC. These skills ... |
A doctor's note does not need to say why a person is being excused. A doctor's note should just say how long a person should be excused, and any restrictions upon returning- none of this information is violating a patient's privacy. It does not. The note does not need to contain any specific medical information, simply... |
Facebook knows your gender, age, likes, dislikes, hobbies, location, job status, relationship status, and it can sell that to advertising companies. Reddit knows you like cat gifs. Reddit's founders sold the company after a year when it wasn't worth very much. Their involvement from that point on has been as employees ... |
They can very subtly change the structure of their skin, which in turn reflects light slightly differently which shows a specific color. Now you might then ask why we don't light up in different colors every time we move. Well the answer to that lies in what kinds of skin cells a chameleon has. Chameleons have a thin l... |
The page is hosted on a server somewhere and the adds are drawing information from a different server. If the server hosting the webpage is slower than the ad host, then the adds can load before the page content. This effect can be removed by manually changing load order for the page, placing advertisements at the bott... |
They have rationalised the process as 'too difficult' already and so don't make a true effort to learn it. 2c Listen to a song in English 3-4 times. Read the lyrics and sing along. Easy right? You will probably remember most of the lyrics after a few times through the song. Now try the same thing with a German or Korea... |
Here's the skinny: We all pay taxes, just like Americans do. The systems are very similar overall, differing in the details, but that's not relevant here. The provincial governments each run what amounts to insurance companies, only they're taxpayer-funded and everyone's got coverage automatically. You get a health car... |
Two reasons: First of all, Disney didn't hire the foreign workers. Cognizant Technology Solutions hired the workers, then Disney hired Cognizant to run their IT. Cognizant probably couldn't hire American workers for the wages, benefits, and working conditions that they were offering. Second, there's an out in the "only... |
It's called refraction. Hot air is less dense than cold air, so it bends light differently, giving it the wavy appearance. |
The efficiency of engines probably didn't improve very much as there is just so much energy in chemical reactions (the same engine is planned to be used in the new NASA SLS as was with the space shuttles since the 80s). There is research into more efficient electric engines but at the moment they aren't powerful enough... |
It's not just your legs, but your hands as well. You are basically shifting your center of mass to be on one side of the swing's chain/rope or the other. This causes the chain/rope to accelerate in one direction or the other according to Newton's law. It's resonance. You are harmonizing your body oscillation with the p... |
These sorts of things vary greatly by where you live. It will be different for different counties and US States. That said, a child over a certain age (14 - 16 depending) will get a choice in the matter. Assuming that the parent is amenable, you can live with whomever you want and see the other one as little or as much... |
They have a hand accelerator and hand brake installed in their car. [There are lots of companies that can install those kind of controls in almost any car.]( URL_0 ) |
Fluorine is *extremely* reactive, so it's got a strong enough electronegativity that it basically forcibly "borrows" the Xenon's electrons even though Xenon was happy with the electrons it had already and didn't want to give them up *or* gain more. This is because Xenon is the largest of the noble gases (besides Radon ... |
Yes. Although it's generally less Hollywood style flying through the air and then dust yourself off and walk away and more roughly the same thing that happens to a person hit by a speeding bus. Yes. C4 has an expansion rate or "explosive velocity" of approximately 29,000 feet per second and can compress air at the lead... |
Your stomach contains acids and enzymes. Acids aren't very good at dissolving greases, bases are much better at it, but your stomach is acidic, not basic. Eating a lot of grease fills up your stomach with something that it can't easily digest, and as a defense mechanism you'll feel nauseated so you eject it from your s... |
A [typical speaker]( URL_0 ) is a cone of paper that's attached to a magnetic system, with the magnetic force moving the paper up and down, according to the frequency of the music or sounds that are played. To make louder sounds, the speaker cone has to vibrate more vigorously, and as explained above, at some point the... |
Actually we do. URL_0 The reason its so complicated is because we have so many dialects, accents, and speaking mannerisms. The program itself needs (I believe) a minute of speech from the subject before mimicing the speech. Hoverboards are easy; you counter the force of gravity by pushing a predictable amount of air do... |
I don't believe this is actually a thing? Atlantic Salmon also frequently have warnings put out about parasite risks. [The NHS publishes warnings in the UK]( URL_0 ) about it. Now you can get sushi-grade fish, of course, but that's fish that has been flash frozen to kill any potential parasites in the fish. That can al... |
In the most basic terms, the government gathers a bunch of money from the tax payers (or from government borrowing) and uses that money to pay for everyone's healthcare in the nation. So the government is the "Single payer" for all, or at least the majority of, the health care costs in the nation. The specifics vary a ... |
The switches are connected with two wires - one wire connects the "up" position in both switches, and the other wire connects the "down" position. When the two switches are in the same position, electricity can travel through the wire that connects them. When the switches are in a different position, the circuit is bro... |
In radio, the further you get from a radio transmitter, the weaker the signal gets until you can't tell if you are seeing a transmission or just background radio noise. With AM radio, this is a problem, because the sound information is encoded in the strength of the radio transmission. The further you are from an AM tr... |
Imagine that the lungs are kind of like sponges that fill the space inside your rib cage. Usually the sponges are wrung out so that they are still a bit moist, but not really wet. Pulmonary edema would be like if the sponge was not wrung out- it is more full of water, which decreases the amount of space for the air tha... |
The color in skin is from a pigment called melanin. Melanin protects the skin from UV rays in sunlight. Too much UV causes a sunburn. Depending on your genes, you make a mix of eumelanin (brown color) and pheomelanin (red color). The brown blocks UV best. The red can actually make the UV do more damage. Fair skinned pe... |
Bergdahl is a very contentious figure and continues to be despised among many in the military. Basically, he was unhappy with what he saw as inadequate leadership and negligence by his superior officers. He apparently tried to voice his concerns to higher-ups a number of times, but did not feel he was listened to. It s... |
C is normally the default internal HDD allocated letter because in the beginning of time A was used for a floppy disk unit and B was also used for removable storage, sometimes a tape drive or similar. Edit: in the 2 minutes of googling I had to do following this comment it looks as though A and B are actually 'reserved... |
Imagine starting with a cube-shaped chunk of play-doh and rolling it in your hands. The corners get smushed, because they stick out. There are still some edges that stick out though. If you roll carefully, you'll eventually smush down all the corners and edges without making new ones. A shape that doesn't have ANY corn... |
Thermal Conductivity is a materials potential to conduct heat. The thermal conductivity of water is about 10^-.3 where as air is about 10^-1.7. This make air much less able to transfer heat therefore 30c water feels warmer than 30c air bc you were warmed by it more/faster. Hope this helps. :) |
When studying ethics in psychology at uni I read about "Little Albert". The short answer to your question is yes, a child can learn a phobia of something not usually thought of as phobia-material. URL_0 In short, they used the techniques of Pavlov with classical and operant conditioning, only Pavlov famously used it on... |
I get migraines and cluster headaches. First off there are different types and different causes. The type that makes you want to drill into your head is usually due to sinus pressure. it feels like something is pushing against your skull and opening a hole will release the pressure. Now, noone really wants to drill int... |
Everything you experience in life - from tactile sensation, to emotion, taste, everything - is processed in your brain. Think of all the senses and chemicals that are produced as input, but your brain is where it's actually experienced. When you dream, it's like a program running on its own. You can experienced anythin... |
Quite simply, we learn to feel calm via some combination of conditioning methods: * Classical conditioning (e.g. you've associated oceans/lakes with another 'stimulus' that naturally produces calm, like going on a vacation or spending time with a SO) * Operant conditioning (e.g. positively or negatively reinforcing the... |
Sympathetic = fight or flight Parasympathetic = rest and digest The vagus nerve is a major part of the parasympathetic nervous system (among other things). It starts in the brain and sends parasympathetic signals to the heart, lung, and most of the digestive tract. This slows down the heart rate and breathing, and stim... |
Palm oil is more versatile than other oils because it has a high melting point. This means it doesn't take as much as other oils to go into a recipe. It also doesn't spoil as fast meaning that products made with palm oil can be kept on the shelves longer, which means companies don't have as many rejected out of dates. ... |
Sometimes your brain wants to include tactile input to a situation, you may find you do this without thought. |
Our perception of depth, especially in pictures where we don't have parallax from our two eyes, is based on subtle lighting and color cues. With a lack of light being emitted or reflected, how else would you see depth? Was thinking the same thing. But what makes objects appear 3D in an image is the shadowing and shadin... |
CBD is non-psychoactive, anti-inflammatory, anti-anxiety, neuroprotective and in many cases anti-tumor. It won't make you feel 'high' in the traditional sense, but it make many people, myself included, calm. THC is psychoactive. It is what gives the intoxicating effect that recreational users are after. When it convert... |
In a solid, molecules are sort of holding on to each other. Heating involves agitating those molecules. Enough agitation will shake molecules free from each other's permanent grasp, and the thing melts. But then, there are some substances whose molecules like clutching to each other very, very strongly. They won't melt... |
If you have been awake for a long time, your eyes dry out. Closing your eyes lubricates your eyes, which feels good. Muscle fatigue is another factor, especially if you've been staring at a screen all day. Another perspective: when you're tired, you want to sleep. Closing your eyes starts to satisfy the desire for slee... |
In the context of Scotland it matters having your own currency as it effects your economy greatly. Ok so say Scotland went with it's own currency the *?* let's say. And on day one it's decided "well we will set the exchange rate to *?*1 = £1. So that's ok everything in Scotland costs the same, if every day you buy a dr... |
The whole order of operations isn't *strictly* necessary since we could use parentheses to show absolutely everything and the maths would work out, but it would look messier than what we can do with the order of operations. There's nothing intrinsically "correct" about it; it's just a convention that everyone's agreed ... |
Men have deeper voices than women because boys experience a rise in testosterone during puberty that makes their vocal cords grow longer and thicker, causing their voices to drop as much as one full octave. Girls experience vocal cord changes during puberty as well, but their voices only deepen slightly compared to boy... |
Imagine you have a function that let's you write f(x + y) = f(x) + f(y) f(a * x) = a * f(x) For any x, y, and a. If we have f(x) = a * x for some x that is not 0 and some a, then a is called an "eigenvalue" and x is called an "eigenvector". That's it. Despite its simplicity, this is an incredibly broad and important co... |
Water out of the tap has gases dissolved in it. Not, you know, a lot, but some. As it sits in the glass, imperfections in the inner surface provide sites for bubbles to form as the gas tries to leave the water. It's a much slower, tidier presentation of the same effect that creates the Diet Coke and Mentos trick. |
Most diseases require medication (or surgery) to deal with the disease, but medication can work in different ways: in certain cases, the medication itself kills the microbes that cause the disease, in other cases the medication simply helps the immune system deal with the microbes. And in a few cases, your immune syste... |
Not an expert on the subject but in my understanding the psychology need for the drug would probably be removed, so the "actual" addiction would be gone. However there is also the physiological need for the drug that would NOT be removed. Meaning that you would still suffer from withdrawal and other symptoms associated... |
Since water is more dense than air and is incompressible, sound waves have a harder time penetrating the water's surface. Also since the water within the lake do not have waves, there is nothing to obstruct the waves in opposing directions. Here's one mechanism that can produce this effect - [refraction of sound]( URL_... |
Moisture stays in the air (in clouds) if there are no pressure or temperature changes to the air. A mountain range typically forces the moist air breeze that comes from a nearby ocean, sea, or lake to go UPWARDS, where the air has less pressure and is much colder. Thus, all of the moisture condenses and unloads from th... |
A standard battery gives off around 1.5V. This is too low to run most electric circuits. A common lower voltage is 3V. To get double the voltage you can connect the batteries in serial with the positive terminal on one hooked up to the negative terminal on the other. The voltage across the two other terminals should no... |
The main issue that Mars has is a lack of a strong magnetosphere. Earth is very protected from solar winds and energetic particles because it has a strong magnetic field. Mars lost most of its atmosphere over the course of a _billion_ years due to low gravity (not lack of a magnetic field, as is commonly believed). It ... |
Kant answers 3 big questions: 1- what is reality? Kant says there's a real world outside of your body. But the way you experience this world (using your senses of seeing, hearing, touching etc.) creates a map, or model, of this outside reality in your mind, which is unique to YOU. Even things like space and time are un... |
Your brain controls your body this way: * Each organ in your body is composed of cells. Each cell is alive, and responds to changing conditions in the environment around it. For the cells in your body, the "environment around the cell" is the blood that gets delivered everywhere; the cells retrieve oxygen and nutrients... |
That stuffy feeling inside your nose isn't all snot. a lot of it is simply the tissue inside your sinuses swelling up and blocking the airflow. think about what happens inside a penis during an erection: blood engorges the tissues inside a penis that makes it swell up and become stiff. The same process happens inside s... |
The motor is still turning an axle regardless of whether it's brushless or not. This movement is going to lead to sound either directly with the axle and whatever it's attached to moving air, or indirectly by the vibration of the parts touching the axle. |
When they do fact checking the actual nightly news part of fox news is a little bit worse than others but not hugely. The big deal is that fox news has very endless 'editorial' sections that are 'entertainment" and simply say things that are not remotely correct or true.

The Web was created in 1989 by Tim Berners-Lee as a means for individuals and organizations to publish documents online that could refer directly to _other_ documents via a "link." 15-20 years ago (i.e., circa 1995 to 2003), a significant portion of the Web consisted of sites, pages, and content generated and maintaine... |
Type 2 diabetes has a lifestyle attribute to it. That means that in many cases (not all) a person's lifestyle can have an effect on their chances of developing the disease. When you consume large amounts of carbohydrates (sugar, starch, breads, stuff like that) it puts pressure on your pancreas to produce insulin. You ... |
Your gut is full of sensors, particularly pressure/pain and taste buds. (Yes, same as on your tongue, just not hooked up to your brain the same way.)
