Why do we tear up when we yawn
Not 100% sure if this is the correct answer, but the act of yawning presses against the glands which produce tears. These glands are like a sac, so pressing against these sacs make the tear flow regardless of if you need it or notI thought i were just weird. So to yawn, i would go to a private place and afterwards pinc...
The new changes to paypal's policies, and why its bad for me.
The big one that's mentioned is the change that you can't join a class-action against paypal so I'll explain that. Lawsuits are expensive. Even a little suit against your neighbor over cutting down your tree can rack up costs from court fees and time spent arguing the case. In a major court case involving a huge busine...
Why do app developers like supercell release their updates/apps way earlier on one platform than the other?
If you're referring to the time gap between Android and iOS releases, the answer is because of Apple. Things get on the Android market very easily and quickly, because the Android market is cool. Apple has dozens of excessive rules and guidelines that they strictly enforce, so they actually look through the app/code. T...

conjecture: English speakers don't watch the shows, so they are not translated. The shows are not translated because English speakers do not watch the shows.
Why is pencil graphite referred to as Lead instead of graphite?
Before chemistry was really a thing, everyone thought that graphite was a type of lead, probably because it's so soft.
Why are the words "Yeah" and "Oh" always in pop songs and said for so long?
They are used as *filler* where the tune requires a note, but the singer doesn't have anything more to say. An excellent lyricist will try to adjust the wording so that not too many of these are needed.Good filler that can make even the most unintelligible lyrics sound intelligible. [Example]
How do certain websites offer free copyrighted movies and television shows without being shut down?
I know of a few websites that use servers that are outside of the US, specifically in regions in which they could give fuck-all about US Copyright laws. Think small eastern Euro countries, and the middle east. I personally met someone who ran an operation remotely in Saudi Arabia, from the US, and literally had $25k dr...
The different branches of Christianity, and why they are no longer combated as heresy
In many Christian circles, this is the analogy that applies: Imagine a target, with three rings. The center, the bullseye, are the core values. I call them "primaries". It's what defines Christianity. Without starting a debate, I'll say that some people disagree on what goes in the middle. These people we 'd call heret...
Where does color goes when the sun "bleaches" it?
It breaks the molecules that make the color, and the byproducts don't have any specific color. The atoms are still there, but formed into different molecules.

issues with the line. there is noise on the line when you call. when you hang up an phone it makes a new connection and this time no issue with the connection. it can be either the person you call or your phone line causing this issue', "They could also be talking to you on speaker phone, so your friend's phone's micro...
Why does inbreeding cause the offspring to have a significantly lower IQ than average? What is the science behind it?
take it that a human body has 2 sets of genes. When a baby is made, half the genes are from the mother and other half is from the father. These genes make proteins which help our body work. However, there are occasionally some errors in the genes which ends up making defective/too much/too little proteins which give ri...
What are some indicators for advancement in relationships?
I'm a little confused as to what exactly you want to know. Are you talking about the stages of a romantic relationship, and if so are you asking for "signals" or are you asking for general stages, like hand-holding to kissing to sex?
Why can't modern houses be economically independent with solar + battery+ a little backup generator just incase?
A) You need a large array of solar powers to provide full coverage to the home B) until very recently, there hasn't really been any cost-effective battery solution for homes C) Most people who live in developed countries don't have to worry about power outages because they are extremely rare. In these countries, it doe...
If we are 70% H2O, why are we considered Carbon based?
The chemistry that keeps us going is based on carbon-chain molecules. We do use water for some reactions but most of it is just solvent for molecules to float around and react in. It's somewhat like why we say tea is a plant-based beverage even though it's mostly water. The interesting part isn't the water.That would b...
Why do we have speed limits rather than a speed range?
Because that's the top speed you can safely do, assuming ideal conditions . When it's raining, snowing, cold or dark, this changes it from being ideal conditions. It's not safe to drive at that speed any more. Worse it is, the slower you need to go, especially if your visibility is impaired. Too much variation in the w...
The world can't agree on standard units of measurement for anything except time. H ow come?
They can and did. ISO standard units called the SI units. Most everyone doing serious business is using them for most everything and have been for a while, non-SI units are just used in day-to-day stuff because people have preferences and it's generally not worth it to, for example, force Canadians to actually measure ...
We all mostly skip or block ads. What makes companies still believe online ads like on youtube is worth investing?
"We" is comprised of tech-savvy desktop/laptop users. Mobile users and most internet users don't use adblock, and their revenue makes it worthwhile.Adding to /r/CatboyMac, only SOME OF YOU block ads. And MANY of you skip them. But the part of the population with the most money to spend often doesn't fit within this gro...
Why is it that plants comparatively much less diverse (only ~250,000 species) than other clades of life?
I don't know for certain, but think about it: Plants are sedentary. They find a particular kind of environment that suits them well and, for the most part, stay in one place for their whole lives. They don't need to develop systems that allow for locomotion. They don't need to develop complex tissues and organs that ma...
Why do we randomly get this weird/burning sensation in the nose when inhaling?
Always assumed it was a dry spot where there was no mucous.Eugh I get this too! I feel like it's when your nose is TOO empy kinda thing.
Are mobile ads intentionally the last thing to load while opening a page, so more people would accidentally click them?
No. Ads are usually provided by a 3rd party company from their servers, not the same server that is delivering the rest of the content on the page, so they can often take longer to load compared to other stuff on the page. They are often also image-heavy, which means they take longer to load than text. They are also us...
why are we producing more aluminium than we recycle if it takes 95 percent less energy to recycle?
Yes, it would be, but then there would also be a finite amount of aluminum on earth and we would never be able to have more bottles and cans than we do right now. The world is growing and we still have a need for new aluminum. People like airplane manufacturers and NASA need lots of high quality aluminum so they are wi...
why are there no comedy categories at the Oscars
Each awards show has their own thing. You're probably aware of the Oscars and the Emmy, but there are like a hundred others with their own style and categories. However you're not alone in your thinking. Not having a separate comedy category has been a regular criticism of the Oscars. They tried to assuage this a bit b...
Why is it when I love someone a lot, that sometimes I have to hug them tightly and it feels like I can't be close enough.
No answer, but that is fucking adorable. I hope you two have a long happy life of being this in love together.This is going to sound like a really snide answer, but really isn't You love them. Go and try to hug the annoying person you don't really dig, it will not last long, probably more like a shoulder check.

Why are smoke shops allowed to sell bongs?
Next time you go there, look for a sign. There will be one saying "For Tobacco Use Only" While bongs are commonly associated with marijuana, they are also used for tobacco and in that regard are perfectly legal. By saying they're only for tobacco it protects the stores from the drug laws you mention. So in order for th...
How does hot water work in hotels?
While all buildings are a little different, most use a single boiler and a recirculating hot water system. Hot water circulates in big loops on each floor, driven by small magnetic pumps. This means the water is "instant-on". The storage tank is kept warm by the boiler and inflowing water is warmed before it goes into ...
How am I a W-2 employee, yet do not qualify for any benefits, including unemployment? Details in comments.
It varies from state to state. One reason could be that you didn't earn enough in at least one of two consecutive quarters. Depending on exactly when your season ends, that could screw you. Or just simply not enough hours. No matter what the reason, I think you're entitled to a hearing. I'm sure that varies as well, bu...
Brief history of Turkey with focus on the modern issues and culture
Perhaps start with this country profile, it has a pretty ELI5 approach and then ask a more specific question.[Here's the CIA's Turkey in a nutshell]
How come Humans can't learn animal languages and communicate to them?
Because animals don't have language. They communicate emotions with sound like angry growls, panicked screams, horny rumbles, and affectionate purrs, but they can't communicate abstract thoughts, form sentences, assign arbitrary names to objects and events, combine terms to make new concepts, etc, which is what we cons...
What do degrees (temperature) actually measure?
At a basic level you can think of temperature as the average molecular energy of a system. Temperature can be measured in different ways, but they all come down to measuring changes in heat energy . In everyday thermometers, what is measured is how a liquid expands with temperature, travelling up the bulb. The expansio...
why is seemingly every photo tagged with a “Getty Images” watermark? How big are they? And are they just an image host or do they also employ photographers?
Getty is huge. They buy images from existing photographers and then aggressively protect copyright. I don't believe they employ their own photographers, but prefer to buy images from others.
Why is it such a big deal that it costs more than 1 cent to make a penny? Shouldn't the cost and production of other coins and bills counteract the defecit of making pennies?
Just because you CAN make up a loss in one are with a gain in another doesn't justify that loss. You could say "sure, I throw away every other roll of toilet paper I buy without using it, but I buy toilet paper at half price." Well, it would be better still to buy that half-price toilet paper and NOT throw any away. Th...
Why do ice cream taste testers use a gold spoon to taste test?
How do you define "common spoon?" At my house, I have metal spoons and plastic spoons . Using a gold spoon allows for standardized testing and, as you stated, to allow for the most neutral taste test possible.
Why aren't any famous people getting assassinated?
In terms of political figures like the president, the Secret Service has gotten really good at spotting that sort of behavior, and stopping potential threats long before it's a take a bullet type situation. Not saying it couldn't happen, but it's not usually something an average Joe would do out of the blue without war...
Why are denim jeans both stiflingly uncomfortable in hot weather and freezing in cold weather?
When its too hot you will be hot in jeans. When its too cold you will be too cold in jeans. because they're midrange pants designed to be durable, not comfortable?
Why are speed caps used by ISP's and how do they work?
CFAggie isn't really right, that was the case before fiber internet and massive technological feats. I was once studying to be a network engineer, and I picked a few things up. They do it because they're greedy assholes. I know that's doom-and-gloom to the point of being laughable, but that's why. American and most Eur...
the oligodynamic effect (i.e brass doorknobs disinfecting themselves after a period of time)
The effect is certainly pretty cool. Essentially what is described is that frequently touched materials can gather lots of microorganisms really easily, just because they're found literally everywhere at extremely high levels. When you touch a doorknob, you transfer the bacteria on your hand to the doorknob. However, t...
I am short-sighted. If I look in a mirror which is close to my face, objects in the distance (in the mirror) still look blurry. Why?
A mirror is not a picture. Put your camera in selfie mode and you will see the background in focus, because the camera in your phone is properly focused and the screen on your phone is a real image. The image in a mirror, on the other hand, is a virtual image made by reflecting light from the real world to your eyes. T...
How do hair transplants work?
Hair from the back and side of your own head is used. It's not affected by male pattern baldness. They take individual hairs or groups and place them on your bald areas. To get more complex, this hair is unaffected by DHT which causes MPB hair loss. Older techniques would use awkward looking groups of hair while more m...
Why some people would rather help an animal than a human?
Speaking personally, animals seem more helpless and innocent. I feel like a human could help themselves in a way that a cat or dog couldn't, hence the animal is in greater need of help.
Why are second (and if lucky) third orgasms in a sex session (with a partner or alone) less intense than the first?
That's funny, my second ones are always way more intense.Male here, adding another "speak for yourself". The third and fourth and above might be hard uh more difficult to achieve, but they are way more intense.
Air pressure in houses? Why do some doors hit a cushion of air when they close, some doors slam when they close, and some doors get sucked closed?
It's depends on how air tight the room is. You will notice this with doors that are tighter to the carpet and not under cut. Take a door that you can't slam because of this and open a window in that room the air will be forced out the window and the door will close easier. Opening or closing a door rapidly will generat...
Why do such well-known companies as McDonald's and Coca-Cola pay tens of millions to be the lead sponsors of the World Cup/Olympics/etc.? Do people really not know these companies at this point?
A part of it is about securing future customers through positive association. If you are 5 y.o. and love football, and everytime you watch it on tv a big coca cola logo is burnt into your retinas, then you're more likely to prefer it once you're older and actually have some disposable income. Thats the idea, anyhow
Hospital Fetal Heart rate and Cervix Monitors
A belt with a sensor is placed around the stomach. The sensor can tell how hard something is being pressed against it. The tensing and relaxing of the uterus puts more or less pressure on the sensor, so it can tell what's going on.
The number system of Graphics Cards
There essentially isn't one. Within an individual product line from a given manufacturer the numbers may mean something, but mostly they are just the name the manufacturer gave to that video card. It's all about marketing. The first number in most cards indicates the "generation" of video card they belong to, but this ...
Why can I hear a TV from another room, even if the volume is off?
Although I can't understand what you're saying in the explanation, I think I know what your'e talking about. Old TVs emit a very high frequency noise that is constantly on, even with the volume muted. you might be hearing this from the other room.
I just saw the Bruce Lee kid video, and now I'm curious how nunchaku work. It seems like an inefficient weapon.
Yeah, they're not exactly great weapons. They're not as difficult as you 'd think to use them, but they're honestly kind of a pain, and certainly aren't as effective as many other weapons. From what I recall of my Asian history though, the reason taht these kinds of weapons exist is because of limited resources. They s...
What does "single payer" mean in the american health care system ?
"Single Payer" means that there is a single entity that handles all of the insurance payments to medical providers. In this case, that payer would be the government. Instead of multiple private insurers that each cover a small portion of the population and each negotiate their own prices for procedures we would have on...
How are branded drinks mass produced? (Gatorade, Monster)

what's an API? (computers)
It's an "application programming interface". It's a defined set of methods by which you interface with functions and data of a program from another programmer.

Why are Japanese fan content creators so much more strict about their activities in order to avoid copyright issues than Western fan creators?
Social responsibility. In general, Japanese culture has a bit more sense of morality in respect to the original creators. They don't want to hurt the creators. Theres also this sense in Japan of following the order of things just for the sake of the law. A lot of westerners will do things they know they aren't supposed...

How come—when looking at the light produced on earth VIA satellite imagery, they are always yellow, when in fact, there are lights of all different colors being produced?
It's not VIA, it's just via, a word. :-) Anyhow, the answer is simple: most electric lights are actually yellow, so when you look at a lot of lights grouped together from far away, you see mostly yellow light.
Why is insurance handled by private, for-profit companies rather than by the government?
> and that's definitely not who I would want backing me if I get in an accident. except that, unless you were criminally stupid when signing a contract, in this particular case you get to sue them, i.e. get the government involved. Under capitalism, the government is the policeman, not the entire economy.That depends w...
How do tunnel builders know where they are going?
i dont know anything about that specific project, but in general there is an engineer that surveys in the centerline of the tunnel using a theodolite . you basically move a known point down the tunnel using the previous point along the centerline as a reference. you offset each point from the actual centerline so that ...
How exactly do Saline pools work?
Salt water pools still use chlorine, the difference is that the chlorine is produced through electrolysis using the salt as the base material. The advantage is that the salt electrolysis process creates free chlorine ions and burns off chloramines . As long as they are maintained they will work just as well at killing ...
Why did I just pay $250 for a passport with a 3-week turnaround, when a driver's license is $25 and take 30 minutes?

Why do aeroplanes/airplanes have headlights?
> Why do aeroplanes/airplanes have headlights? Aircraft commonly land at night when it is dark. Being able to see the ground when coming in for a landing is important because they need to touch down at a reasonable speed. So not to put too fine a point on it, they are so the pilots can see when it is dark. You know, li...
Why do i sleep better when its cold?
The temperature that your body sleeps at is lower than the temperature your body maintains the rest of the day, this is for energy conservation and obviously to let your body rest.

How if I have some software that requires a product key that you must pay for, that many people can use the same key?
There are two ways that a product key can be validated. The first way is that the program "phones home" to check that the key is valid, and is tied to your account. This type of validation means that the same key can only be used once. But the other way that a key can be validated is if there is some algorithm that gen...
How does a contagion spread from contact with an open wound to the target organ in the body ?
Generally through the blood stream or the lymphatic vessels. When a contagion attacks a specific organ I.e. Hepatitis, it is because something about those cells allows that particular pathogen to attack/reproduce better than they do in other cells. They don’t move towards that organ specifically, they just keep getting...
How does a state minimum wage increase impact people?

Why do trained muscles get more volume rather than density?
Skeletal muscles are the muscles that you use for voluntary movement like your arms, legs, etc. They're made of myocytes, which have a limited ability to divide. Other cells in your body constantly divide, like your skin or the inside of your mouth . When a cell is stressed out, as in it receives stress from either hor...
Why was the European Union created?
Also, food-security. During the world wars food would be a scarce resource. The EU subsidizes farmers in the EU so they can compete with cheap food from outside the EU which was made with a lower wage for the workersThis could probably be more accurately answered on [/r/askhistorians]
what happened to the hole in the ozone? Did we fix it, is it still there, was it never that big of a threat?
We found replacements for chlorofluorocarbons and drastically cut down the rate at which we released them into the atmosphere. The holes are still there but have stopped growing and are on the path to recovery.It's still there, it's just that because it's over Antarctica, we don't hear much about it. It doesn't really ...
When I put pressure on my eyes for an extended period of time I see really cool patterns that alternate. What is that?
your eye is full of liquid called the vitreous humour. when you press on your eyes, you're increasing the pressure of that fluid inside the eye; that in turn causes pressure to be applied to the nerves in the back of your eye, on your retina. those nerves get confused and start sending out random signals that you see a...

Do uncontacted tribes know we're here, like we are aware of their presence?
My impression is that most of them are aware that some kind of big, huge, technologically advanced world exists, but they don't know shit about it. Commonly they are uncontacted because they want to be: being contacted tends to screw them over. Either they have few useful skills and end up in the bottom of the heap of ...
Why can't we just gargle an antiseptic to get rid of a sore throat?
Because the source of your sore throat is not lying around on the surface of your throat, but within the soft tissue surrounding it.

With the recent "Infinity Table" posts, can someone explain how they work?
First, let's explain what a "one-way mirror" is: It is not a mirror that only reflects light going in one direction. It is a _partially reflective mirror_ that allows some light of either direction to go through, and reflect some light of either direction. What this means in practice is that depending on relative light...
Why are PIN codes not needed for online transactions?

What is an orchestral conductor doing, and how can everyone follow what he's doing regardless of what instrument they have?
He's keeping time. Each swing of the arm is a "tic" in the temp of the piece which all musicians, regardless of instrument need to keep in synch. He can also make larger or smaller movements to indicate changes in volume. And he will cue sections or individuals for specific parts of the piece that highlight that musica...
Why can't governments print "temporary" money to cover important expenses?
They do, and it causes inflation because the money doesn't have any material value behind it. Money is just something we use to represent value. Without creating the value, the printed money isn't anything more than paper, which in turn, makes every piece of money less valuable.They do, but they can't print "temporary"...
Why can humans eat almost anything, yet so many foods like chocolate, grapes, and xylitol are dangerous for dogs and other mammals?
The premise of your question is basically flawed. We can't eat almost anything. About half of the red berries in existence are poisonous to us but not to birds, for example. The same is true about mushrooms. Also, not everything that is edible is food. Uncooked grains are edible, but you would eventually die if that's ...
How are those huge cranes that work on skyscrapers setup/made taller/moved to really high floors?
They're modular and self-assembling. The first structural piece under the rotation head, the lifter module, is more complex than the rest; it includes slides and jacks. The complete assembly process involves anchoring the base and setting up the horizontal arm. Once that's ready, the lifter module jacks up the head and...

During the Middle Ages, what would happen if a country invaded another, and the invaded country couldn't afford to fight so it surrendered, but the invading country kept on fighting?
That's not really how treaties work. Treaties aren't like "you get to keep all the land you 've taken," they always specify very exact borders. If Country B truly had no will to fight, they would have given up all of their land . If Country A didn't take advantage of the situation and got a treaty that wasn't as favora...

The US has more youth playing soccer than any other nation in the world. Why don't we have our own Messi?
We have a lot of kids who play soccer, but the vast majority are in recreational leagues, not serious youth development programs like Messi went through. Those are growing along with the domestic league, though - the MLS Academy system just started four or five years ago.US television doesn't view soccer as a potential...
Cosplay; is it just done for an event? Does one wear their outfit on multiple, random occasions? Is it just made for the photos?
It's usually for a convention, which will run for several days. Some people wear the same costume to multiple conventions, others make a new one for each one.
If there are concentration camps in North Korea that are similar to those found in Germany during WWII, why hasn't a military force such as NATO intervened?
This is asked a lot, but here it goes. North Korea would react violently if any force tried to offer aid to those in the camps. If North Korea acted violently, there would probably be a war. If there were a war, China would be upset. China doesn't want millions of refugees and nuclear radiation at it's borders.
Why is mercury the chosen substance for determining the temperature?
We actually don't use mercury anymore, we use alcohol. But the simple answer is because as a liquid metal it is conductive, and expands and contracts predictably with temperature changes. Further, unlike water, it's freezing point is low enough there is little change of that happening, and even if it somehow occurred i...
How do women's menstrual synchronize if they spend a lot of time together?
They do not. It is a common misconception. They will occasionally *overlap*, in the same way as if you watch a bunch of cars with their blinkers on, but they don't synchronise.
Why do lights and stars sometimes appear to have points sticking out of them?
If you are thinking of photos then they are called [diffraction spikes] and are caused by the wires that keep a mirror in place.
I am confused about how many KB are in 1 MB. Some sources seem to say 1000 and others say 1024. Which is it?

Why are people so drawn to shiny things like minerals and gems, especially to the point where they're used in things like fine jewelry and crowns?
Shiny things are usually rare and/or valuable. We put them with other shiny things as a show of wealth or status, like the British Crown Jewels or the Hope Diamond.
What does growth mean in terms of a countries economy?
The way I learned economic growth, the ways economic growth is measured is by increasing the production capacity the country has .
