Why is pepperoni considered the default topping on pizza?
Pepperoni, Sausage and just Cheese are "default" or common because they are cheap enough ingredients and the market majority likes them.
how is the weight that we lose excreted out of our body's?
We exhale it. The fat is metabolized for energy, leaving water and CO2 as wasteTaken from a different Reddit post: " Cool TedTalk video explaining the science behind where the weight goes: _URL_0_ "
Trolling and troll accounts on Reddit.
Trolling is making a disingenuous post design to provoke a response. It is like going to a friend and saying, "oops, I accidentally scratched up your new car in the parking lot, sorry dude." then laughing at his reaction when he get upset. Trolling can be funny when it is clever, especially if you can push someone being self righteous over the edge and into crazy talk. But most of the time it is just clumsy attempt to through a bomb in a crowdMany people will tell you something like "Trolling is making a disingenuous post design to provoke a response." that is a terrible definition. Trolling is manipulating people to do something with the expressed purpose to humiliate them for choosing to do it.When there is no real threat of retaliation, it's exciting to see what you can get a person to say. In the real world, you'd get punched in the face.
Why are the people of reddit so completely angry about things that are reposted? Do you truly believe that everyone has seen everything you have seen all the time?
Two reasons: 1. It fills up the feeds of people who spend a lot of time on reddit. They want to see new things instead of old posts. 2. The reposter is getting attention and karma for something that they did not create and many people have a moral problem with that.
How can you "buy" an election? Why does it work if we regularly hear about the concept in the news?
Its a reference to when the super rich like to Koch brothers and Sheldon Adelson or corporations like Comcast and oil companies spend tens or hundreds of millions of dollars to finance propaganda through advertising from bogus think tanks and lobbyist groups for certain candidates. When that candidate wins, thanks to a nonstop barrage of mud thrown at opposing candidates, those politicians are more apt to vote in the donors' interests in order to keep the flow of money coming. People who don't have those resources can't compete, and their interests are seen as not being met or drastically undervalued to politicians. It's expected that the Koch brothers alone will spend nearly $900 million on various campaigns in the 2016 election, most of it funneled through dozens of SuperPACs with names like Americans For Prosperity or Freedom Partners Action Fund. They Kochs end game is to get politicians elected who will further their own personal agendas. Why spend so much? Because with dozens of politicians in their pocket, they stand to make billions from oil and industrial business should legislation like oil pipelines and abolished environmental standards and tax cuts become law.
How did China become a permanent member of the UN Security Council?
The countries considered "victors" of World War II were included in the permanent member. China actually played a rather significant part in World War II.Buzz word is '4 policemen'. This would later grow to 5 with the inclusion of France to the group of 'policemen' or, as they are also known, permanent members of the UN Security Council. How these 4 nations came to hold such sway over an institution that 'regulates'* inter/intranational politics is based on Roosevelts real politik opinion. He believed due to their power and priviledge these 4 nations should form an alliance to maintain global stability. Each of these Nations would have a portion of the world in their sphere of interest that they would be responsible for maintaining 'peace'°. * Implying the UN has any real authority save as an American foriegn policy tool similar to the World Bank or IMF. ° Maintaining peace or Economic, Military, and Political domination of smaller Nations.

How does coloring black and white pictures work and how do you know which colors to use?
If you mean "how do you change an image to greyscale" Color has three "dimensions". Hue, saturation, brightness. Hue is the "color family". and it goes in a circle: red, orange, yellow, green, blue, violet, and back to red. . Saturation is the colorfulness of the color. Low-saturation means the color looks dull or grey. High-saturation means vivid. Every time you look at a color wheel like [this one], the colors are displayed at the highest levels of saturation Brightness is how light the color is. This is different than saturation, though. Low-brightness colors look black. High-brightness colors look white. To make an image to greyscale on a computer, you just set all the saturation to as low as possible. . In other words, greyscale images are *only* concerned with the brightness of the image. In art, brightness is usually known by another name: value. With a pencil, for example, how hard you press against the paper determines the value. . Ideally, a black and white image can be made by only using mixtures of black and white. It works by overlaying a color onto the image, oftentimes shading and using multiple layers to get the right look. At least that's how I used to do it in photoshop. Getting the "right" colors was more of a judgement call but it can go faster if using one or more colored source images. There are plenty of step-by-step tutorials online if you're interested in learning how to do it yourself.
How do antidepressants work? If I'm depressed about my student loan debt, how is a pill gonna make me forget about it?
They're not? You're mixing up clinical depression and being sad. Clinical depression requires being 'depressed' for an extended period of time without a reasonable cause. You have a huge amount of debt and your mom died? That's not clinical depression, it's being depressed for a good reason. As for how antidepressants work, they correct abnormal brain chemistry. There are a lot of different possible causes, but it's all about neurotransmitters or hormones that aren't working right. Antidepressants work by increasing the production or absorption of neurotransmitters, or by reducing reuptake.
Criminals in films spray paint cameras but they show their face anyway. Why?
You saw the person spray paint the camera. You didn't see the person commit the crime. At least, not from that camera. When it's time to charge the suspect, if the camera footage is the only available evidence, that distinction could prove crucial.Its usually a trope. The only reason this would be otherwise useful is to reduce the polices knowledge of the interior. They have to be more careful when entering because they cant rely on the camera footage effectively slowing them down.
Joel Tenenbaum has to pay 675,000 to the RIAA for pirating 31 songs. How does an average dude pay for this kind of fine?
Probably what will happen to Mr. Tenenbaum is that he will be subject to a 'Wage Garnishment'. Folks who owe child support will be very familiar with that term since it's also used against them. _URL_0_ Assuming that he or his lawyers don't find a way to duck the $675k fine, this means he owes a debt of $675k. Of course, barring winning the lottery or becoming a successful businessman, most folks are never going to be able to pay that much in their entire lives. That means that a court, probably not the same one that convicted him, will issue an order saying that he has to pay so much out of every thing he ever earns up until he has paid off his debt which will likely be never. Because child support disputes, tax debt, and other kinds of debt are so common, most businesses who have more than just a couple employees deal with wage garnishments as a matter of fact. You can't be legally fired for having a wage garnishment, nor can an employer legally refuse to hire you for having one. However, assuming that he works and doesn't find some other way around it, that garnishment is going to be a stone around his neck for a long, long time.
When jumpstarting your car, why do you connect the black cable to the engine block instead of the black/negative terminal?
Sparks near the battery can cause hydrogen fires. Sparks near the engine block are much safer. That said, modern batteries are sealed and pretty safe, but safer is always better.
Why does re-heating something in the microwave make it soggy, vs the oven or toaster oven?
When you heat something in the oven or toaster you are directly exposing the food to heating elements that give off intense radiation and heat which stimulate all kinds of chemical reactions in the upper layers of the food, usually causing a toasting and hardening of the outermost layer. Microwaves do not work by exposing the food directly to heating elements like ovens do. Microwaves work by firing microwaves into the food at a particular frequency which causes water molecules in the food to flip back and forth violently, banging into other molecules and thus creating heat inside the food. But this method of heating is not suitable for causing the dramatic chemical changes you see in ovens that are responsible for a good browning and toasting./u/scienceteacherguy is absolutely right, but maybe too much for ELI5.. conventional ovens and toaster ovens use methods that apply heat to the air and to the surface of the food. This causes the surface to dry and brown, depending on the intensity and time the heat is applied. If you don't heat things long enough, the inside of this food may be cool or left unheated. microwaves operate by directly heating specific molecules. Water and some fats are 'excited' by microwaves. The microwave oven heats the water inside your food, which will in time.. create steam, and the steam tries to escape the food. That moisture on the surface of the food is the cooled steam. If you kept heating it in the microwave, the steam would totally escape - leaving the food hard and dry. Similarly, microwaves are good at melting fatty foods, like chocolate or butter. Be careful, because these fats will make the container hot, too. Because some plastics have molecules very similar to fats, those plastics can easily stain, other even melt in a microwave.
Why bacon is seen as a manly food and seen as the best food ever? Is it it's high calorie and fat content that makes it extremely palatable to humans?
Because the people that like it dont judge taste by how many calories or grams of fat. We judge taste by simply the smile it brings to our face when we eat it', "it's the kind of food that provides the energy and motivation to smash a wild animals head in with a rock
Why can we heal broken major bones?
It's the same trait that allows us to heal minor bones, just on a larger scale. Healing broken bones is just a single act, healing the bone, it doesn't depend on if the bone is someone small like a finger bone, or a rib, or something large like a femur or tibia.
What happens to light beams when the source has been "turned off" or extinguished?
Think of a beam of light as being similar to a stream of water being sprayed from a hose. Except instead of water molecules moving relatively slowly, you have photons moving at the speed of light. When you shut off the hose, the stream stops spraying more water, and all of the existing water molecules keep traveling until they hit something. Likewise, when you shut off the light source, no new photons are generated, but the ones that are still "in flight" keep going until they hit something.Imagine light being tiny single particles that are emitted instead of a continuos beam. Much like water from a water hose. If you turn of the emitter, the particles that have been sent don't disappear or anything similar, they keep traveling. However, light travels so fast that for the human eye this is essentially not noticable. If you turn of the light in a room at night, it seems to become dark instantly and that is because the light just travels to far to notice any difference. However, imagine we could delete the sun from one moment to the next, i.e. just make it disappear. Now, because the distance between the earth and the sun is so large that light acctually takes about 8 minutes to get from the sun to the earth, we would still notice sunlight for the entirety of the 8 minutes after deleting the sun. This sunlight is the light that has been sent of directly before deleting the sun, but hasn't reached the earth yet.
Why do stimulants cause some people with ADHD to feel drowsy?
For every drug that is supposed to do "Y" to someone, it does "X" for a small percentage of people. This is what is known as a paradoxical reaction. It is very well accepted in pharmacological study. As to *exactly what causes it*, that is a very large and broad question to tackle. But a good way to understand it is to understand that *biological states are not polar opposites*. So, you're confused because you know that "stimulants" are "drugs that make you awake". However, stimulants make some people sleepy, which you think is the *opposite* of "awake." But it isn't really that simple. Biological states like arousal, hyperactivity, drowsiness, fatigue; these are complicated biological states that are often more intimately related and more complex than people understand. Paradoxical reactions usually derive from abnormal neurochemistry. Pharma companies aren't *super* thorough when putting out a drug. They come up with a compound, it does something, and they go to market. Stimulants like adderall, for example, work on the dopamine system. The work they do on the dopamine system in *most* people produces focus, energy, and altertness. But if someone's dopamine system is different than the norm - if perhaps they process it differently, or if adderall also tinkers with *another* neurotransmitter in an unexpected way - voila! Drowsiness. If you go digging down the rabbit hole deep enough, you are likely to find one or several studies of people studying paradoxical reactions in whatever drug you're thinking of specifically, and they'll offer some very technical biochemical or neurological hypothesis answering your question.
Why do Canadians use bags for milk but not other beverages?
I live in Ontario and I remember seeing juice in those bags when I was younger It was the same exact bags that the milk comes in, and you would put it in the same exact milk jug thing and it just worked. I remember my mom would freeze them, and as they thawed she would turn them into some sort of "poor mans slushy". They were pretty delicious. So they did sell juice in them once! But like I said, it was a long time ago. I don't remember ever seeing it since then. This doesn't really answer your question though, sorry!Canadians put their milk in bags? Canada .sometimes it seems like an entirely different country.As a Canadian… What the shit? I've never seen milk in a bag. Not once.Canadian here. Not once have I seen milk in a bag.This is a myth. ONTARIANS buy their milk in bags. Albertans don't do this; we are logical beings who realize that jugs and cartons are the way to go.
When two black holes merge who attracts who?
When any two massively dense objects get near to each other they both attract one anotherThe same as with a person and the Earth. We attract each other, but Earth is so massive that the tiny bit of attraction we make is negligibleThey both gravitate towards each other in a hypothetical black hole collision.
Why was Cherice Moralez reported as being raped?
Statutory rape is rape. Media in particular is cautious about not referring to things like rape as what they are, as it can be seen as extremely offensive otherwise.
Why are most bluray torrents (1080p) not at the quality of true bluray (1080p)?
Blu-Ray discs are big. They can hold 25-50 gigs. Depending on the movie, all of that can get used. Nobody wants to download a 50 gig file, so encoders try and compress it as much as possible while keeping the quality as high as possible. It's nice to start with as high def as possible an original, and usually Blu-Ray's about as good a starting image as you can get. So, long story short, you didn't download the blu-ray as a torrent. You downloaded a video thing that was compressed from a blu-ray. There are some folks out there that distribute losslessly-compressed, perfect blu-ray movies, but those are huge.I believe thats more referring to the source they ripped it from than the resolution, which is all about file size. A blu ray movie sits on a 25gb or 50gb disc, and movie torrents, even high quality ones are what, 5gb-10gb? One fifth the space equals one fifth the resolution. Surely someone who knows more than I can step and be more specific though
My tongue at the end of a USB cable attached to my laptop counts as an unrecognized device
Yes: the port can detect *something* is attached, but can't tell what it is, because your tongue doesn't communicate via the USB standard :-P
How is a spider's silk stronger than steel?
It is by relative strength, yes. If you had a string of steel as thin as a thread of [spider silk], the silk would be stronger.It is both cases, if you made a huge spider silk line or shrunk down steel to be like a single strand of spider silk. The factor that determines strength is the stress that the material can withstand. Stress is force per area, like pounds per square inch . The size of it is independent. Example: A silk string that is holding 2 pounds and has an area of 0.001 square inches has a stress of 2000 psi. A steel bar that is holding 1000 pounds and has an area of 1 square inch has a stress of 1000 psi. If the steel breaks and the silk strand doesn't, it is stronger because it can withstand a higher stress.
Why does it hurt to wash my nostrils with pure water while salty water is fine?
The insides of your nostrils are lined with mucous membranes, which are made of cells which are filled with slightly salty water. Water can flow through cell walls through osmosis, and in such a situation the water flows in a way that equalizes the cell's salinity with the water around it. So when you pour unsalted water in your nose, the millions of cells suck up the less-salty water and end up bursting. Ouch!!! If the external water has equal salinity, the water doesn’t flow either way and your cells remain intact. Ahhhhh…..
why do we stretch? And does it feel so good to stretch?
Stretching tenses the muscles which helps pump blood back to the heart, which is part of the cardiac cycle. The 'feel so good' part of has to do with the sudden rush of rich oxygenated blood, which feels good. Hope that helps.
Why does a bad smell become unnoticeable after spending a short while next to it?
Our senses are designed to emphasize new information. Once information is stale, it's less useful to us, so we tune it out. Smell is just the same as our other senses in this regard. Our eyes adjust to light or dark. Our ears adjust to loud or quiet. Our noses adjust to smells.
If pain occurs when something is going wrong in my body, why doesn't losing feeling in a limb (limb falling asleep) hurt?
The nerves have blocked, your body is trying, but the telephone lines have been cut. The tingling after is the nerves comming back onlineAn interesting tangent I would recommend going on would be to look up "phantom limb pain." It's basically what you're talking about, but more extreme. People who have lost parts of their body will sometimes experience sensation, pain being the most talked about, in the part of their body that no longer exists. It's an interesting condition, and so is the treatment: using a mirror box.
Why aren't we constantly terrified about dying or knowing how insignificant we are?
Some of us are, this is a very real & common problem. It keeps the anti-anxiety med makers & the shrinks in business.
why are the Japanese dying at 110 when southern Utah Summers easily hit 115-120 and everybody's fine?
1) Acclimatization. They are not used to the weather and so the abnormality of it can cause their body to overreact. They also do not know what to do to handle it, such as drink extra water. 2) Much of Japan is far enough north that they do not use AC in their homes or buildings. Many literally have no place they can go to get out of the heat. 3) Humidity. Japan is an Island nation so surrounded by water. It is on average far more humid that the arid state of Utah. When air is humid it is already at or near saturation point for water vapor so you sweat does not evaporate efficiently if at all. This means that you body's self cooling method does not work.
Why is there so little research on the effects of Marijuana compared to other drugs when it is not only the most common drug, but one we are actually thinking of legalizing?
Well, it's very very difficult to ask the public to volunteer to help test the effects of a drug that can, as silly as it is, ruin your life. This has kept any studies from happening - a schedule 1 drug cannot be studied. Hell, as far as the DEA and many people are concerned, the very fact that it's schedule 1 means that it has already been determined to have no medical use whatsoever.
- The problems with economy/business regulation or: the advantages of deregulation
regulation is corrupting. regulation reduces competition. regulation enshrines obsolete business practices in law. regulation is expensiveVery simply: Too little regulation: What if the private sector messes up! Too much regulation: What if the government messes up! Middle of the road regulation: What if the private sector and the government mess up together!
If the Taliban has spokespeople and twitter accounts, why doesn't we just track them down and end them?
Press confidentiality. A journalist who meets with the Taliban is both blindfolded so as not to reveal their location and can't reveal their sources.The Taliban are not as shadowy and secretive as you think they are . The Taliban governed Afghanistan for ~ 5 years and were considered by a few countries to be the "legitimate" government as they had de facto control, even though everyone else in the world considered them to be backwards nerf-herders with a deposition to violent thuggery and repression. And what do we have to gain by killing spokespersons? They're actually a valuable source of information. We get to know what they consider important, hear them take credit for stuff, try and piece together their overall strategy, etc. Same reason why the CIA didn't shut down jihadi web forums, just monitored and infiltrated the shit out of them. Track them, see if they are in contact with any high Taliban military officials, and then kill those who pose a clear threat to US national security.Re: online presence, they take steps to make it hard for it to be traced to a person. Among the steps 1.) use public internet cafes in a friendly country 2.) send a low-level flunky to upload the message 3.) use VPN 4.) others Even if the US can see which IPs are used for the twitter account or blog post, the person is long gone by the time it is sent. Also, even if you did catch the guy he's got no useful information. In other words, the US has better intelligence on the leaders of the organization and it's not worth going after the tweeter.
If cooler conductors transfer electricity better, why would cold on a sore muscle block pain receptors?
Because pain receptors work mainly on chemical reactions, with electricity playing a secondary role. Cold slows chemical reactions.
Why air moves in planet earth?
Air does move in a box! It just have to be a big box before you'll notice. The reason is that hot air is lighter than cold air, so if one part of the box is heated faster than another part, the air at the hot part will start moving up, which leaves space for the cold air to move to the hot area, which lets air from above the cold area fall down, which lets the hot high air move there. How fast the air moves depends both on how big the temperature difference is, and how far apart the hot and cold points are. All of this helps the entire box maintain approximately the same temperature. Same thing applies to Earth, except it gets a lot more powerful since water vapour and the hot areas is even lighter than the hot air. The Sun heats the equator more quickly than the poles, so air starts trying to move between them only to take a wrong turn because Earth is spinning. It heats land faster than water, causing the wind to blow one way during the afternoon and the other way during the evening if you're near the coast on a sunny day.When the sun heats parts of the world, it causes the air in those parts to expand, causing movement. When air cools down, it contracts creating vacume.
What is the point of a "smart" credit card (with the chip)?
The main benefit is that in order to clone the chip, you need to get access to the private encryption keys on the chip itself. Short of breaking into the bank/credit union's computer systems, you're not getting those. Meanwhile, cloning the magnetic stripe on the back is a simple matter of buying $150 worth of equipment on Amazon and finding some blank hotel keys. Chip cards can also be set up to require a PIN for purchases but the US isn't doing that for the most part for credit cards*. Many other countries have for their cards though which may cause issues when trying to use an American chip card somewhere that isn't capable of accepting a signature . ^* Some American credit cards do have a PIN but it's only intended for those ticket machines/gas pumps that I referred to above. [A couple of cards] require PIN for everything but they're fairly difficult to get and are the exception rather than the rule.The chip is much much harder to copy than the magnetic strip. Your card needs a "password" so that the bank knows it's your card, right? The strip says "My bank account number is 123456789 and my password is 13371337". Anything that can read it can see that , and if you have the information, it's relatively easy to write it back to a blank card, so they get a copy of your card. With the chip, it's a two-way process. The bank's system can tell the chip "Here's some random data: SLGHWKRHTWEJRTCWAERR. Please encrypt that with your password and send it back". Then the card does the encryption and sends back "I'm bank account 123456789 and the answer is KUERY#IT#@Y$%@#RQWFV$T". At no point does the reader, the network, or anything else get to see the password. The only theoretical way to get the password is to either break the encryption , try all possible passwords or take apart your card and examine it with an electron microscope .
How do protons stay bonded together. I thought 2 positively charged particles pushed away from each other like magnets.
They do. In the universe, physics has established that there are 4 fundamental forces; gravitational, electromagnetic, strong, and weak. You likely heard of gravitational and electromagnetic, but the force responsible for holding together the nucleus of an atom is called the strong force. As its name implies, it is the strongest of the 4 forces. The strong force by itself has difficulty holding two protons directly together, so it uses neutrons as spacers between them. The fact that the strong force is so strong is why atomic bombs and stars release so much energy. The reason you likely do not encounter the strong and weak forces daily like you do with electromagnetic and gravitational is because the strong and weak forces have a limited range in which they can operate on, while the gravitational and electromagnetic forces have infinite range, but the strength declines with distance. The strong force has different force with different distances, but it becomes nearly nothing at about 1.9 femtometers, or about 0.0000000000000019 metersThey would, if there was only the electromagnetic force to deal with. But that's only one of the 4 "fundamental" forces EM, gravity, strong nuclear force, and weak nuclear force. The [strong nuclear force] binds protons and neutrons together in the nucleus. Over very very short distances, the strong nuclear force is incredibly strong about 100 times stronger than the electromagnetic force! Having the neutrons in the nucleus along with the protons is what binds the nucleus together, using the strong nuclear force.
Why can I eat salt and drink water, but not drink saltwater?
You can drink salt water. There's no law against it. You don't die if you drink it. It's just that salt water has enough salt in it that it doesn't hydrate you. In fact, it dehydrates you. . If you drank nothing but salt water, you'd get too much salt and die. When you eat salt and drink water, you are taking in water that can hydrate you and keep the salt diluted. If you drank way more water than you ate salt, you would also die, because your salts would become too diluted. If you ate too much salt, even while drinking only freshwater, you would still die. TLDR; not drinking salt water is something mentioned to people who might find themselves stranded at sea without freshwater. It is not a general rule.
How do anti-satellite missiles work?
These missiles work a lot like the rockets used to launch satellites into space, except that they don't go as high and the payload isn't a satellite, but a kill vehicle. The kill vehicle is typically just a mass with a very complicated guidance system on it. It doesn't carry explosives because when it hits the target, it will be going so fast that the force of impact alone is enough to wipe out the target. Beyond that, details are rather scarce, but it most likely receives radar guidance to the target from powerful ground stations and then once it gets close, the kill vehicle will probably use something more precise like an infrared seeker to guide itself onto the target.
How do animals such as chameleons and some squid know which colour to change to?
I can't answer for squid, but chameleons don't know what colour they're changing into: it's more of a signalling of mood, temperature and probably a few other things I'm forgetting", 'If I recall correctly, they perceive the background colours through their eyes and also foto receptors in their skin. However, we still do not know exactly what the process behind it is really like. . Edit: this applies to cephalopods. As the others have said, chameleons do not change colours to match their surroundings.Chameleons don't actually change color to match their environment, they do it to express emotions or communicate.
How does cheese get its flavor? What differentiates cheddar cheese from american cheese? Is it ingredients or something in the process of it being made?
Cheese is made by adding colonies of certain types of bacteria to milk. The bacteria eat proteins and sugars from the milk and produce new compounds that make the milk thicker until it becomes cheese. Depending on what types of bacteria are used, the byproducts will be different and the resulting cheese will have different properties.
Whats the physics behind pumping your arms when you run?
Your arms counterbalance the swing of your legs. Try running with your arms down Fred Flinstone style and you'll notice it is actually more difficult.
Why are American police generally despised while the military is very highly regarded?
The military don't take actions against the citizens of the country, they're regarded as protecting the interests of the nation as a whole. The police are active in the community to serve and protect, this leads them to having more contact with the individual citizens and the perception that they're the enemy because it's an entity that is easily associated with preventing people from doing something they want to do.People have to deal with police. If people had to occasionally deal with a testosterone laden 18 year old with an assault rifle, they would probably hate the shit out of themMilitary are risking a lot more, especially front line troops. Whether you agree with the war or not, they are risking their lives to defend our country. Police have a much lower risk of dying, and a lot higher risk of negative interaction with the public. You never see the result of a dick on a power trip in the military, you see it on a daily basis with the police.My theory is that people see the military as a force to protect themselves, whereas they see the police as a force out to punish them and catch them out. It's unfortunate that, whilst there are exceptions, a lot of people don't realise that the police are out to look after you, not to harm you.
Why does heat hurt more than cold?
I think it's just personal experience. Cold hurts me more than heat. It hurts my body parts like my nose and hands, whereas heat doesn't hurt me, it's just annoying and bothers me", 'This is how I see it: Think about what heat and cold actually are.Heat is essential molecules that are moving around at a more frantic rate. Fire even gives the appearance of frantic movement. Cold is when molecules move around at a very slow rate or stop movement altogether. Burning and freezing to death are both fatal but fire is a much more violent and frantic form of the temperature spectrum and therefore causes a more extreme pain.Not specifically speaking about weather, think about temperature variation in general. Water boils at over 200 degrees Fahrenheit. Water freezes at 32 deg. If the body temperature is about 98 deg, the variation of heat is always always greater than the variation of cold. Don't compare a flame to ice, compare a flame to dry ice, and then you'll have more of an equal pain scale.
Why does YouTube buffer but TV doesn't?
Cable sends the exact signal you need for a tv show and has been optimized for that functionality. The show actually comes through the cable in a direct signal and is pretty much a direct line to your cable provider. Each channel has its own signal coming from the provider so all you have to do is tune to that signal and read the constant stream of data. YouTube can be any random data stream and competes with other network traffic. Meaning any other application using Internet or any device using Internet on your network will start slowing it down for others. YouTube also has to send these random data sources from their servers to your home. Data packets can be lost and other network interferences can cause buffering. That means the data has to travel further which introduces a slew of other possible network issues. It's the combination of things that actually cause buffering at times.
How/Why do dryer balls work?
Theoretically, the dryer ball stops the fabric from sticking to itself, so when you run it through the dryer, it fluffs up instead of just flopping around stuck together. Whether it actually does lead to softer clothes is still under debate. Popular Mechanics ran an article on this that you can read here: _URL_0_
why Argentina wants the Falkland Islands so badly?
Argentinian desire for the Falklands is inversely proportional to how well their economy is doingProximity, they think because its closer to them they have more right to it than the people living there.Argentina thinks the islands are theirs, and that the British stole them. They don't read reddit comments explaining why they are wrong, so that's their position and they stick with it. This also provides them with a good populist cause to distract the citizens when things aren't going well. This is happening for a while now, and that's how you probably learnt they want them _badly_. They had been wanting them for a long time, but in the past you would only know it if you were interested in international diplomacy.
Why wasn't the world settled West to East?
There were actually people in the Americas before Europeans came over the atlantic and evidence suggests that they came over the Bering Straight land bridge from russia to alaska when the sea was lower due to half the world being covered in glaciers.
why is it, that when you take any body part out from underneath a blanket, you become freezing. But when you have your head out the whole night, your fine?
Your temperature sensors can only measure change in temperature. That is why metal feels cold , you are feeling the rate in which that heat is transferred to or from your body. Your body under the covers would be warmer, so when you remove the blanket, it cools quickly, feeling cold. Your head is in equilibrium where the warmth from the brain cancels out the cold from the room, in total having no net change, as such you don't feel warm or cold.
If my skin never touches my eyeglasses, where does the oil on my glasses come from?
They do contact skin at points and by putting them on when you touch them. OR from frying bacon
How can I wipe 30-times after taking a dump and it just never gets clean?
I would imagine the composition of your feces has something to do with it. A normal, healthy, and regular bowel movement should be one or possibly two solid masses that hold themselves together in such a way that smearing does not occur. Those optimal turds that result in the one-and-done wipe with the toilet paper are the product of a healthy diet rich in fiber. The never-ending sludge I may assume you are experiencing is what happens when a poor diet prevents your excrement from binding to itself to create a solid, healthy brick that glides out as if someone buttered your asshole. My suggestion would be to cut your sugar intake, increase your fiber intake, and drink lots of waterHave you tried moist wipes? It like 2 wipes and your doneBecause you have a bit of poop right inside your asshole and when you wipe the pressure causes the paper to contact that poop turtle ..viola, poop on paper!', "I've heard that if you eat a lot of fiber in one day, then it decreases the amount of times you have to wipe. Someone on /r/fitness said that if you have to wipe more than three times, you need more protein
When an insect or similar gets stuck in a fast moving vehicle, do they just have to start a new life or would they try and find where they were previously?
Insects do not know where they are to begin with, so it doesn't bother them. Insects don't really *know* anything. They simply don't have a complex enough nervous system for that sort of thing.I always think about that when a bee gets stuck in my car. Like they have a hive and home and stuff. Do they fly back the extra couple miles or just find a new hive or what?
What would happen if you were swimming in a body of water struck by lightning?
It depends on how close you are. Pretty sure I read it's something like either 30 yards or feet is still potentially deadly in water.You might find these previous posts helpful: _URL_0_
Why when we squint our eyes do we see a squiggly line?
Sweet. I love this question. I used to tell my doctors I could see these but he always said they were 'floaters' I was like no! they are cells, I can not directly look at them.. Okay.. So.. This is a thing known quite commonly as the [Blue Field Entoptic phenomenon]. You can click the link there and see a wiki on this. However.. The short story is that you are seeing is brought on by white blood cells passing through capillaries in front of your retina! How awesome is that? It's also a lot more noticeable in blue light as the red blood cells absorb that light leaving you to see the effect of the white more easily. You don't see them directly in the focus of your vision because there are no capillaries there. See the link in this explanation to see the cool details.
Why is it so expensive to go to college in the United States?
Because US schools are built on the foundation of "Better Research Better Education" which is generally saying the better the schools research department is, the better the school will be, the rarer the degree and the better it will look if you attended. Therefore we have an economical arms race where every school is dumping money into research grants, improving research facilities trying to attract the super star research professions while neglecting the programs they already have in order to seem like an even better school, so they can bring in MORE STUDENTS and get MORE money so they can neglect MORE programs to get MORE super star professors. What it creates is a scientific arms race. Which is kinda awesome for college level research , but not for incoming students who are milked to be turned into valuable research dollars. And this has become very very good for US schools. The US leads the world in college education while being ~30-40th in Primary/High school education, which is quite a jump. Buuut it creates a massive coast gap.
How safe are parachutes exactly? How often do they fail?
Parachute failing, yes. Close call, no. There are some complete mishaps, but if well maintained, well inspected and packed property, they're safe.
Why do headphones label each earbud?
There are two reasons: Reason 1: Some ear buds are designed to fit a specific ear. They might be shaped such that they only really fit in the proper ear. Reason 2: Most audio is mixed in stereo so that the audio isn't exactly the same going to each ear. For music it doesn't really matter if you mix up the left and right channels, but for anything that involves video, you'll have sounds that need to come from one side or the other of the image.
Why is the term "God-fearing people" seen as a compliment? Why not replace it with something like "God-loving"?
In this case, "fear" is being used in it's older, more general sense, referring to showing respect or awe. So, God-fearing people aren't afraid of God, they respect himGod was explicit in his desire for you to fear him, for him to be revered and have great impact on our lives.
What do modern Russian spies sent to live in the west, actually spy on?
Defense contractors. Getting the designs for missiles, submarines, and similar weapons of strategic importance can help a spying country in two ways: copy the ideas rather than doing their own R & D, figuring out how to defend against or defeat those weapons in a warPretty much what you 'd think, I 'd assume. Individuals and organizations of varying importance to Russia and its allies, the "lay of the land," and to provide cover/background for other agents. For example, the various US diplomats, major federal agencies, Big Oil, and various tech companiesWe just busted a ring of them stealing Wall Street secrets and planning economic sabotage: _URL_0_
Does coffee actually stunt growth in children and teens? If so, how does this work?
It's been studied pretty well that there caffeine cannot stunt your growth, so you can rest assured that your height is just genetics. I've been drinking coffee since I was 5 and I'm 6'. Enjoy the caffeine! Embrace your height.
how does a thermostat switch things (AC, header, lights) on/off?
If you have your own heating system, you should already have one. IF your heat is by radiator, then you control the heat at the radiator. If you have some other whole-building heating system, then it's likely you won't be able to install your own thermostat, unless the system can handle it, but most apartment managers would not agree if the building doesn't already have individual thermostats. In a house that has it's own furnace, the thermostat is hooked to a relay, a device that lets a small amount of power close a switch that passes large amounts of power, which then allows the furnace to run. That's a very simplistic explanation, but sufficient I believe. Thermostats typically won't switch lighting, unless they are hooked into an automation system like Insteon or similar. But how do things like that switch? Relays.
How do film actors do two films at once?
Voice acting and on-camera acting are usually handled differently. Generally, for a feature-length Hollywood film, there will be a chunk of time where the actors are full time dedicated to this movie. This approach usually is the most cost-effective when it comes to crew and location/staging . Once the actor and crew is done with their part, the film moves into "post production" which can actually take a VERY long time but the actor is now free 'd up to work on other projectsIt is literally their job to be able to play multiple roles. Especially voice actors. Their skill set is to be able to deliver a great character performance though voice. Ultimately it is the voice actors responsibility to deliver that performance. If the voice actor cannot switch back and forth, that is their problem, and if it becomes an issue, they probably will not get much work in the future.
Why do I and professional athletes pull hamstrings all the time but you never see a cheetah or a gazelle pull up lame with a strained calf or something?
You know, if I was a cheetah, I'd probably enjoy a little strained calf every once in a while. I'm not a cheetah, but it still sounds pretty good. Maybe with some sourdough toast?", 'Cheatahs and gazelles do not have the same fan club. They also suffer from physical injuries, such as appendicitis, heart disease and strained muscles. There difference is that there are fewer cameras there to record it.
why do people walk in a circle when they're in a fistfight?
I'm no professional boxer, but I spar once a week. Constantly moving is good for three things: * It makes you harder to hit* It makes looking for openings of your opponent easier, since people can only protect their front and not their side* It hides your attack movements. Good power comes from low in the body, so it is more difficult to predict where a blow is going if your whole body is moving. Because you are moving and always trying to keep your arms between you and your opponent to block, the result is fighters moving in circles.
Why do gas stoves start at the highest heat setting instead of the lowest?
For lighting. The gas comes out at maximum so it will reach the pilot flame and ignite right away.
If my son is highly allergic to eggs, why is he not allergic to chicken?
Egg is made out of egg stuff, which you can be allergic to. As the chicken grows, it eats the egg stuff and turns it into chicken stuff. Once the chicken is ready to hatch, the egg stuff has been completely used up. All that remains is delicious chicken stuff.Because an egg has all these different proteins inside it to nourish it into a future chicken. One of those many proteins in an egg tricks your son's immune system into thinking it's a virus and causes a very strong immune response which leads to an allergic reaction and even anaphylaxis. Side note: If your son is highly allergic to eggs, caution when getting him a flu shot. Vaccines are incubated in eggs and we commonly want to give patient's a different vaccine than the typical on when they have a strong allergy to eggs.I’m curious about this too. My hands break out and itch when handling raw chicken, but I am fine handling cooked chicken and eating chicken.
How do those machines in gas stations work? Like, where do they store the gas? Why do they require us to turn off our cellphones? What's the calibration for?
Gas is stored in underground in large tanks. You can see where the tanks are by large, round, often slightly raised fill ports that will be off in an otherwise empty corner of the gas station. They are filled by tanker trucks, you will occasionally see them parked at odd angles surrounded by orange pylons. The thing that you park beside is a pump that pumps gas from the underground tank into your car. The pump has a gauge that measures how much gas is dispensed. The gauge is calibrated so that if you pump 1 gallon, the gauge shows 1 gallon. This is used to calculate how much you pay for your tank of gas by multiplying how many gallons you pump by the price per gallon that is set by the gas station. The gauge is calibrated for 70F, so you actually get more or less gas if it is a really hot or cold day. They ask you to not use your cellphone, don't smoke, and don't re-enter your vehicle simply to avoid sparks which could ignite the gas fumes. In reality, a cellphone isn't likely to cause a fire, they are just being cautious. Inside the nozzle there are actually two pipes, the inside one pumps gas, and the outside one is under vacuum to suck up the fumes. Getting in and out of the car while filling up is a bad idea. It can cause a build up of static electricity which can ignite the gas fumes. As for cigarettes, the cigarette itself is not actually hot enough to start a fire, but you definitely wouldn't want to light one near the pump.
Why does drinking water after a workout make it easier to breathe?
It is not because water contains oxygen molecules. We cannot breathe the oxygen presented to us in that manner. We breathe O2 molecules, which are 2 oxygen atoms bonded together, whereas water is 1 oxygen and 2 hydrogen atoms bonded together. Remember we can't breathe underwater! Anyway, while I'm not sure that we really breathe easier after a drink of water, I can put forth a few reasons why it might feel that way. Water would cool us down, so we would feel more in control and less hot and sweaty. Water would satisfy a "give me this now" feeling as well, further calming us down. It's also another activity that allows time for the body to recuperate, since you're essentially resting. I know that after a workout, and I'm breathing hard, and I stop breathing to get a drink of water, I come up with big deep breaths trying to catch up on that air I missed. THEN the breathing gets easier. I attribute this to the reasons mentioned in the above paragraph. Friendly reminder that everything after the " can't breathe underwater!" line is still conjecture, and I don't have any sources for what I 've said here.Here's my opinion and I am not sure how it make sense.Drinking water not only swallowed the liquid, but also some of fresh air. And that action make your breathe paused, which result to deep breathe. Simultaneously, the water you drink calm down your body. All of these caused you feel easier to breathe.
Why does one aching tooth cause other teeth that are healthy to hurt as well.
Referred pain. Basically, pain in one area causes nerves to fire, and the chemical and biological processes from that can spread slightly, causing other, unaffected nerves to fire.
How is snow formed?
way up in the clouds, it's very cold. Water vapour begins freezing piece by piece to tiny particles of dust called a "Nucleus." Once those particles get too big and heavy, they fall to the ground. If the temperature is high enough, that snow will warm and melt as it falls to become rain. If it is winter, that melting doesn't happen.
how does dry heat cause nose bleeds?
I believe that since the skin inside of your nostril is usually kept wet with lubricating mucus to at least some degree, drying it out would cause it to contract and crack more easily, causing a nosebleed.
How can a small amount of medicine (like a pill) affect my whole body?
It's not unreasonable that small amounts of things can have a dramatic effect on the body. A tiny thorn only effects a very small number of nerves which sends a small number of signals to your brain. Yet it can overwhelm your senses. A small amount of poison from a sting can effect your body. Also consider that your body produces minute amounts of hormones to control your body functions. This is the only way that your body can function. It has to be designed so that small amounts of substances can produce large changes. This is true for any effective system. A large company is controlled by a few people at the top. An airport is controlled by a few people in a tower. An army is controlled by a few generals. Similarly, your body is controlled by *signals* in the form of chemicals. That's what many medications are. They are signals. Those chemical signals end up creating various larger changes in the body.
Why do nut packages display the warning "May contain nuts" instead "Do contain nuts"?
I assume you mean packets of peanuts. Peanuts [aren't actually nuts]. Someone with a nut allergy may not be allergic to peanuts, and vice versa. So if you had an allergy to nuts, but could eat peanuts fine, it is important to know if the packet may contain traces of nuts.The warning is mandated in some states to protect those with nut allergies. They just put it on all the packages of everything processed in a plant that works with nuts and that may be shipped to one of the those statesNuts may not be one of the ingredients but they may find their way in there if made in a factory that uses nuts. They need to protect themselves against lawsuits.It's easier to have one phrase than several grades of phrases. You can attach whatever legal protection you need to a single phrase.
why did UK sign up to the China’s Asian Infrastructure Investment Bank and USA was so object to it?
Because there is soft movement in Europe to attempt to remove some of the influence that the US government and corporations are abusing in the world..
This one should be tricky: Aristotle's unmoved mover argument.
it's fairly hard to explain, but I'll try my best. The basic Greek View was that everything the world was cause and effect. As a result, the universe is the effect of some cause. So, what was the cause? Nut what caused this cause? Following this train of logic you either have an infinite chain of cause and effect, or there was a starting point, an effect without cause. If this is confusing, sorry, ask some questions and I'll try to answer it.
What exactly is it in water that we need to live?
Water is used as a solution fluid, lubrication, as a cooling agent, and many others. It is not broken down.The most significant thing about water is its hydrogen bonding capacity. Closely behind that is its neutral pH and then comes abundance. Very few things hydrogen bond like water does. This allows it to be used to modulate molecular structures and thus activate or deactivate specific reactions, depending on how water is applied. The nature of hydrogen bonding is a charge polarity in the water molecule, where one side is more negative than the other. This causes water to dissolve ionic compounds, because they can interact with these poles. Hydrogen bonding is so significant in water because of a property called electronegativity. Oxygen is one of the most electronegative elements, right behind fluorine. Hydrogen isn't the least electronegative, but it pales to oxygen. Electronegativity is a measure of an atom's pull on an electron. Hydrogen is fairly stable without its one electron, so oxygen pulls two electrons in total, making the oxygen side more negative and leading to hydrogen bonding with the now positive ends of other water molecules. The neutral pH is great because every molecule behaves differently when it picks up a hydrogen ion or loses one. Several molecules, including proteins and DNA have their function change with pH and water provides a nice and stable setting. Someone else said it works as a coolant. This is because water has a really high specific heat compared to most other molecules. This means it takes more energy to heat water the same amount than it does to heat another molecule . So, water heats more slowly than iron with the same energy input. This makes it something of a temperature buffer. This is related to hydrogen bonding, too
Why do we bite our nails? It is a completely useless function, but is still embarassingly addictive.
Humans also pick our noses and scrape wax from our ears. It's not useless, it's grooming, and despite being gross it's essential for hygiene. Imagine if you NEVER picked your nose. Tissues don't do much for really stubborn dried blobs.
Why is it that when I'm under mental duress, physical pain helps it go away?
Pain causes your brain to release dopamine. It's why cutters cut etc. Also physical pain can be a pretty good distraction from stress so you momentarily change focus as well.
E: Is it theoretically possible to manipulate genes in their early stages to produce an endomorph, mesomorph or ectomorph?
First off, it's worth mentioning that Sheldon defined discrete somatotypes for the purpose of using them to draw conclusions about personality. Nowadays it's pretty widely accepted that body type isn't a reliable gauge of personality. Could you **theoretically** manipulate genes *In utero* to control bone structure or fat distribution? Probably. But both of those factors seem to be controlled by a *lot* of different genes [[1]][[2]], so doing it in practice is another story entirely. is some related reading on genetics and adipose tissue distribution, in case anyone's interested.) Alternatively, could you manipulate genes to control a person's metabolic rate? Maybe, but probably not to the extent you'd expect - differences in metabolism [are a minor component] of differences in body weight and composition.
how does cloning animals work?
Here's an analogy: Imagine every person has an apple which define them and sex cells are half-apples . When sperm and eggs merge; there are now a whole apple . Now imagine the egg as a basket with a half-apple . The half-apple is taken out of the basket, leaving an empty basket. A whole apple is then taken from a non-sex cell of the clonee and put in the empty basket. The basket now has only the donor's apple, making it a genetically identical fetus. Congratulations, you've cloned a human! **TL;DR : If you're cloned, you're a basket.**
Could you separate an electron completely from an atom?
Certainly. If you excite the atom enough, an electron flies off. If you pump enough electrons into metal they bunch up on the surface and start to fly off. This is the principle of the electron gun inside the cathode ray tube - at one end of the tube is the gun, which fires a stream of electrons, which are directed by magnets to hit points on a phosphor-coated piece of glass at the opposite end of the tube. Have you ever heard of "ionizing radiation"? X-rays, gamma rays, and so on? The word "ionizing" is referring to the fact that the radiation has enough energy to know electrons free from atoms. Ever hear of beta radiation or beta particles? Those are very fast-moving free electrons produced by the decay of radioactive elements> So is it possible to completely seperate an electron to where it merely exists by itself and is not attached to any nucleus or should I say attracted to any other protons? A common example of this would be an electron gun such as in any CRT television or monitor. They will of course by their nature be prone to pairing up with protons, but they can certainly be separated and flung in a direction as desired.Yes. There's many ways to do this, but one is thermionic emission. If you heat up an object and place it in a vacuum, it will spit off electrons, just like it spits off photons. So yes, electrons can be separated.
How is my radio's reception affected by my physical position around it?
Same way that when you stand in front of a light you make a shadow. When you stand between the radio source and the radio receiver, it blocks the signal. Hard mode: radio waves don't act like light and they actually bounce around a lot. As long as the antenna gets hit "enough", the signal is strong. So depending where you stand you can actually make more waves bounce ONTO the antenna, giving a better signal. . . . A VR thing where it would let you SEE radio waves would be pretty hipHumans are big sacks of salty water, we make pretty shitty antennae, but antennae none the less.
Why can I "feel" things about to touch my skin without having actually made contact yet?
1. hair.2. it might be hot or cold 3. it can block wind, draft.4. you see it and your brain tricks you5. you know it's there and your brain tricks you. Sorta related, I suggest you test this theory in a truly dark environment . I once thought I had the force until I endlessly bumped into things in a truly dark space.
Archaeologists, how do you know that damage to bones was done prior to death?
When a bone is injured, it heals, even if badly. Signs of that healing can be seen, The healing signs alter over time, thus a deduction can be made of how long before death that the injury occurred.
What exactly causes hiccups that seem to last forever?
Hiccups are caused by the irregular, uncontrollable movement of the large, sheet-like muscle between your chest and belly called the diaphragm. The main reason the muscle suddenly acts up is because of irritation to the muscle. Blood, a full stomach, hard to swallow food, reflux from the stomach and sometimes an irregular contraction can cause this to happen.
Would fire be considered matter or energy?
Fire is matter releasing enough energy to become red hot, like a stove is red hot. It's just air that is as hot as a stove is.
Why is it so socially acceptable to refer to someone as 'white' or 'black', but never 'yellow' or 'red'?
Language just develops in different ways, the ways that race is presented in colour is very interesting.\r\rFor example Chinese people thought of themselves as white for years. When what we now know as "white" people first visited china then in Chinese they were known as "purple" people and thought of as barbarians for having hair on their bodies.\r\rIn this day and age however some languages have kept some labels we now see in English as unacceptable. In brazil yellow is still used to mean east Asian people. In South Africa "coloured" is a genuine term used on the census whereas here in England it is seen as a racist term.Because white and black have become socially acceptable identifiers. Yellow or Red have not. Those people say I'm asian [insert particular country/region] or I'm native american [insert particular tribe] It's just a thing about the vernacular. Not unlike how 'gay' is an acceptable descriptor, but 'faggot' is not. It's just about what is socially acceptable and what is not. People still know what you mean when you call a gay person a faggot. The chromatism of a descriptor is not relevant, It's all just about descriptors.The white and black issue was brought to a much more prominent forefront in the last century. We never had a very substantial cultural revolution over native Americans or those with Asian ethnicity like we did with those of African ancestry . Sometimes I'll have to describe a "black" person to someone and I say "His skin is brown " because I just can't bring myself to state that someone is black when they're not even charcoal gray.
How do game engines or physics engines for video games work or how are they actually made?
Most games have several main components: Graphics, audio, input, physics, AI, and logic A game engine helps automate many of these tasks. For example, the graphics section of a game engine might have a model handling component. This section would help with loading the models into memory, putting them on the screen, and probably some other stuff. In addition, some engines also give you a level editor, which helps you create the levels and gives you an easier interface than just working with raw code. I hope this wasn't too confusing and helped a bit.
Why did the population of a lot of large cities decline between 1970 and 1980.
The largest factor is that many of these cities were industrial giants. Manufacturing was huge. To save money, many of these jobs went overseas. Electronics, motor vehicles, steel, textiles - all started to be produced elsewhere. When these jobs left, so did the people. They moved to cheaper, less developed areas they could afford. Meanwhile, cars kept getting cheaper. It means people didn't have to live in cities to work. They could have their spacious affordable house in the burbs and commute in. Meanwhile.. As these suburbs grew, they developed their own businesses that catered to those communities. And with informations technology becoming standardised , suburban neighbourhoods grew exponentially.
What is "Clearing" and how does it work? (Finance)
Do you mean clearing as when money has to clear to close out a transaction? Clearing is the process of verifying that the payment interest that has been proposed to cover off a transaction is valid. E.g. when an electronic transfer takes place it is only when the bank with whom the money is lodged transfer the money to the bank to which the money is being paid that the money can be said to have cleared.
What makes 50 the magic number when it comes to the number of states in the US? Is there potential to add more someday?
Mostly coincidence, the US happened to run out of territories suitable for statehood at 50 . It is possible the desire to reach an even number accelerated the push for new states, and once reached, sapped enthusiasm for additional states. That is merely speculation, but in 1994, Michael Moore's *TV Nation* ran a poll, and found that "14% of Americans surveyed agreed that Puerto Rico should not be the 51st state because 'that extra star would make the flag look bad.\'"', "There have been many campaigns to formally make the US Territory in Puerto Rico into a State, but thusfar they have all been fruitless for various reasons. Guam has also been considered for Statehood, but I think they're pretty much independent now. Other than that, the only territories the US controls are parts of the mainland of other countries that are far too remote to properly manage as a State.
Why do we still feel the waves the night after being in a wavepool/ocean?
Actually, there's no definitive answer to this one although it's a regularly reported phenomenon. It could be because you are still feeling the effect from the frequency of previous stimulation, or it could be because you 've got used to adjusting your gait or posture while at sea and then don't modify it when you're back on land. Personally, I don't buy this second reason because I 've felt the "illusion of self motion" after a day on the water when I'm lying in bed. So I'm going with answer "a" but as I say, nobody really knows! If it's causing you a problem, have a read of [this] where people discuss medicinal answers to this problem.
Why is it it legal for a P.I. to do their job (follow, take photos, rummage through trash etc
They are regulated by a branch of the state government. The process and requirements vary by state, usually requires relevant experience but not always, usually involves a testing process, always involves paperwork and fees paid. Not cops by any stretch, but licensed and given specific powers, with penalties if they abuse them. They are more tightly controlled than bounty hunters.following someone isn't illegal. taking photos of someone while you're on public property isn't illegal. rummaging thru a trash can on public property isn't illegal. you're not going to have a problem with legalities if you don't break the laws.They are registered, and take tests that prove that they know the regulations they are under and what is and is not legal for them to do. Following someone is not illegal for anyone. Neither is taking their photo when they are in a public place, or if you are in a public place and can see the person. Also anyone is allowed to go through trash that is not stored on private property .I think it's easier to approach the issue like this: everything is ~~illegal~~ EDIT: legal, except stuff that is prohibited. In most places, following people and taking photos are legal activities. Rummaging in trash, I can't comment on.Following is not illegal , trash is no lnger yours when you put it out, cops routinely go through it without a warrant. However the trash company does own it. Pictures are not illegal of taken from a public area.
eBay, Amazon (to name just two of many) make billions in the UK but pay hardly any tax in the UK, why doesn't any government do anything about it?
Example: Company has to pay more taxes. Company pays more taxes for the first year. Company relocates, 1000s of jobs lost. Company no longer in the country, so no longer paying taxes. The jobs are also source of tax money, as all employees would pay income tax, so the country would lose that too. And of course unemployed people cost a lot of money. So basically you would lose the little amount of taxes you get directly, all the indirect taxes, and 1000s of jobs, and you'd have to help all those people now unemployed.
How can they "confirm" a Tornado and the intensity after the fact?
> How can they know there was a tornado? I'm sure all of the visual sightings and reports and path of destruction is a big clue. Unless it was a tornado-shaped herd of rampaging elephants. > Then, how can they deduce the level from that? The basic tornado intensity scale - the Fujita scale - is measured based off of the damage caused. So they go in, see how much the tornado fucked up the place, and rate it accordingly.They look at the damage. There's a certain kind of damage, a pattern to look for, that *only* a tornado is capable of. If they look at damage and say "only a tornado could have done this," then it's confirmed. What else can spread debris over hundreds of yards in every direction from a narrow path of destruction? Straight-line winds or micro-bursts can sometimes cause *similar* damage, but it's distinctly different than what a tornado - a small, focused area of violent swirling winds - would do. As for rating, they look at *what* was damaged and *how much.* Different objects and structures are capable of withstanding different wind speeds. Old, brittle trees are often the first to go. Young, mature, healthy trees are harder to pull up. They might look and say "Structures A,B,and C should be able to withstand 200 MPH winds, and they're still standing. But structures X, Y, and Z should only withstand 150MPH winds, and they're rubble. Therefore the wind was likely between 150 and 200 MPH." Note that this is done using general guidelines and not any detailed analysis of the buildings in the area.They take a look at the damage caused. Because of this, if a mile-wide 'F5' only came close enough to knock over your lawn chair, and did nothing else, it counts as an F0.
How do batteries in series work?
You can skip trying to think of electrons in the circuit, or whether the poles are electrically insulated. The + and - ends of an AA battery, for instance, are at a 1.5V potential difference. When you connect two terminals with a wire, you essentially make them have the same potential . This means that connecting one AA's + end with the other's - end causes them to have the same potential. But the free - end of the AA is 1.5V lower than the connected terminals, and the free + end of the other AA is 1.5V higher than the connected terminals. This means, quite simply, that between the two free terminals there is now a 3V potential difference. You successfully created a 3V battery from two 1.5Vs. EDIT: If you really want to think of electrons, with an AA battery, if you connect a load to it, the electrons will be running from the - terminal to the + terminal . Meanwhile, inside the battery, a chemical process transfers charge from the - to the + terminal at the same time to balance out the charges. If you connect two batteries in series, the electrons from one - terminal go to the other's + terminal through the load, and between the batteries they do the same , and the same process happens inside both batteries. There's nothing inhibiting the flow of current. < -- electrons to load --| -- inside battery -- > | < -- electrons -- | -- inside battery -- > | < -- electrons from load --|", 'The + and - of a battery are not insulated, they represent a different level of charge, which for the AAA, AA, C & D range is a difference of 1.5V when making a circuit the -charged electrons are "driven" around the circuit in order to create an equal distribution of charge .When you put more than one battery in a series, each battery adds to the difference in charge from one end of the series to the other.
Why do I sweat so much at night?
I don't want to alarm you but this was one of the symptoms I had before getting severely ill. Do you get quickly tired ? For example, after running for a bit ? Does your face seem a little fatter than before ?Do you cough without any apparent reason ?
How does a country -test- a long range missile
> Do they launch an actual rocket? Yes, this is perhaps the most important part of a "rocket test". > Do they just launch something with gps on it? They launch a rocket with some method of tracking it, but without a live warhead. The tracking method probably will not be GPS unless it is the US or a US ally, as the GPS system is a US military system and the ability to track very high speed objects such as missiles is a restricted capability. If your cell phone for example was accelerated to mach 3 its GPS decoding chip would shut down. > Long story how does a country say we can launch anywhere? Countries don't *need* to ask for permission to do anything, they can just launch whatever they want. However in turn other countries can get twitchy if you look like you are attacking them so most will warn that they are conducting a test .They do launch a missile. They'll have a set of objectives such as range, accuracy and not exploding on launch. A missile can have longer range than tested. It's possible a test doesn't meet the maximum range of the missile, but the designers and engineers have determined that increasing the range wouldn't be an issue during an actual use scenario.
Why do some formerly obese people have a lot of skin to remove and some don't?
It's all a matter of how fast you lose the weight. Gaining weight is a natural process. The body is meant to gain weight when it receives excess energy that it does not use. Just as gaining weight is natural, so is losing weight. When you lose weight in a healthy way the body slowly removes excess skin with your fat. This is how people on The Biggest Loser do it, and how you are supposed to lose weight. But if you use drugs or surgery to lose weight, you can lose much more weight much faster. After liposuction, for example, the body obviously couldn't work fast enough to keep up with the sudden loss of 50 to 100 to 200 pounds, so there is excess skin. This is usually solved with a tummy tuck or similar skin removal surgeries. This is obviously the unnatural way to lose weight, and it can have side effects.
Why do many programmers/technical people prefer Macs over PCs?
It varies based on industry too, there are definitely a lot of developers who prefer Windows-based dev tools. The real deciding factor is where your code is ultimately going to run: because it's probably not going to run on just your personal machine. & nbsp; If you're say, a video game developer, you're probably going to code on Windows because most gaming PCs are based on this platform, and your test builds of your code are probably going to run the same on your box as your customers' boxes. & nbsp; For web development, many webservers are running Linux or another Unix based operating system. Macs are also Unix based and feature the full set of tools for remotely working with Unix servers packed right in, so you can test projects locally, easily put it on the server and be pretty confident it'll play the same. There's also a lot about Unix that's designed to be very developer-friendly and buying a Mac gives them all of that, plus the ability to rely on Apple's support and service if something goes belly-up on their computer and they don't want to fix it.
What exactly does the outcome of the Turkey referendum mean?
Turkey is a mixed political system, with a president and a parliament headed by a Prime Minster, balancing power . Recep Tayyip Erdoğan served as Turkey's Prime Minister beginning in 2003 and then President since 2014. During his time in power, he's tried to consolidate power within his own office and move Turkey in a more authoritarian direction. He's back by Islamist groups that had previously been shunned by secular military establishment that has ruled the country by junta in the past. In July 2016, there was a failed attempt by the military to overthrow Erdoğan in a coup d'etat. Following then, Erdoğan has purged civil society from political opponents, who are overwhelmingly secular. He also used it as a pretext to push for constitutional reforms, which needed to be passed in a referendum . The reforms remove many separation of powers that existed in Turkey: it diminishes the role of parliament and the judiciary and gives more power to the executive branch, headed by the President.
CERN's testing next week to find Parallel Dimensions
The imminent testing is recommissioning with beam. Collisions won't happen for a few months. There's no magic way of trying to do something exotic with the LHC. It just collides beams of protons , and the detectors measure what happens. No one says "this week we'll try to make black holes" or "we'll try to make Higgs bosons". The detectors are built and operated with various physics processes in mind. We can't measure everything perfectly and we certainly can't record every event. LHCb, for example, is optimised for detecting the decays of heavy *b* and *c* quarks. ALICE is optimised for quark-gluon plasma. This parallel universe/extra dimensions stuff came from some theorists saying something along the lines of "If we see it would imply " ).They're just playing with one of a number of possible theories for physics beyond the Standard Model. It sounded sensational so was picked up by the news.
