What is a mortgage? A reverse mortgage?
A mortage is just a loan for a house or other piece of real estate. It is similar to a car loan except that it is usually for a much higher amount. They are generally for 15 or 30 years and have an interest rate between 3% and 6%. A reverse mortage is something that old people get when they run out of money or have no one to give their home to when they die. The bank will pay the home owner a specified amount each month and when the term runs out, or the person dies, the home becomes property of the bank. The bank will then sell it and make a profitLet's say you want a new video game. It costs $60 and on your $5 a week allowance, that would take you 12 weeks to save up. So you go to your dad and you ask for an advance on your allowance. He says sure, but since the point of him giving you an allowance is to teach you smart money habits, he tells you you'll need to pay him interest, 5% which works out to $3. You can have your video game now, but you have to pay him back a total of $63 instead of $60, and it will take you one week longer. You 've lost some money, but you 've gained the benefit of having what you want right now. That's a mortgage. Now you have your video game! It's a year or so later, and you find yourself short of cash. You ask your dad if he can help you out and he tells you sure, he'll give you something called a "reverse mortgage" on your video game. This means that he'll give you a loan now, and if you ever sell that video game, you have to give him the money to pay off that loan. Again there's an interest charge as well. Best I can do in terms of ELI5, hope that helps.
How were the laser effects done in the original Star Wars trilogy?
Rotoscoping is the correct answer. Rotoscoping is defined as any technique whereby animation is created on top of live footage, either with the intention to replace it entirely or to integrate it into the original shot. The technology we use to achieve this in modern day filmmaking is different from the techniques used on the original star wars films, but the intention is the same. I'm not sure the exact process that ILM used on the first movies, because there are a lot of different ways to do rotoscoping, and they invented most of the technology they used in those films. Very early forms of rotoscoping involved drawing directly onto film stock, once the original scene had already been shot. Its possible the star wars films employed this same method but I can't say for certain. Source: four year filmmaking/animation degree", '[Here's a link] to a Star Wars mega fan site that has a "how to" section on how the effects were created - and how they can be replicated for animators and amateur filmmakers. Hope this helps.
- Why are sporting events such as boxing matches on Pay Per View while events such as the NBA Finals and the Super Bowl widely televised?
Fans of a team in a team sport can watch it play dozens of times per season, but fans of a professional boxer can only see him fight a few times a year. So boxing has to make *all* its viewership money on a few big-ticket fights per year while team sports can have seasonal TV packages. Even the big fights don't attract enough viewers to make ad-supported or long-term subscription television more profitable than PPV.Ad revenue. The Superbowl is going to run for hours, including a big-name half-time show. You can sell lots of ads, and thus pay a lot for the rights to broadcast it. With boxing, a 3rd round knockout means not very many ads. Boxers don't want to stand around and cool off while there is a "TV time-out" Boxing is a fragmented sport. There are mutiple associations that control the title belts. Additionally each of the boxers is a single entity. They promote themselves, sometimes inside a larger promotional company. So each company is trying to maximize how much money it will make. Floyd owns his own company, so he is not splitting with anyone else in that sense. In the 70s, 80s, and 90s, the manager of the boxers became as well known as the boxers because they ran the promotion and thus controlled a lot of the money the boxers made.
What is so golden about the golden ratio?
Not much, really. It is a number that crops up in nature a fair bit -- in the arrangement of leaves on a stalk, for example, or the shape of a snail's shell -- and perhaps because of that it is sometimes thought that things that are in golden ratio to each other are somehow more aesthetically pleasing -- "golden" in that sense. Some artists -- for example, Dalí -- did occasionally use the golden ratio. Leonardo da Vinci seems to have thought that the golden ratio was significant. The problem is that an awful lot of otherwise very clever people then fell over themselves to find the golden ratio in every great work of art, from Leonardo's Mona Lisa to the Parthenon, but there is no actual evidence the artists concerned ever did use the golden ratio to construct their works. Basically, any time anyone drew a logarithmic spiral over a painting, or a rectangle with sides in golden ratio to each other, so that they appeared to match something, they cried out: "See! Golden ratio!" when it was most likely simply a coincidence.Nothing in particular. It's just a clever-sounding way to point out when something is approximately half again larger than something else, which occurs about as often as you'd expect such a vague, general notion to occur, be it in art, nature or anywhere else.
How private prisons make money.
They charge the government a set rate per inmate for the cost of running the prison, which includes a profit marginOn top of getting government money to run them above and beyond what it costs them to actually be run, they employ inmates at extremely low wage jobs like telemarketing ) for $0.20 to $1.00 an hour. Not hard to make money when you literally pay your employees pocket change and they have no other employment optionsBasically the government pays you per person you are housing, then you spend as little money as possible making life comfortable for the prisoners, because that money is yours now because while you are morally bankrupt you are on the other side of the bars.
If I have an eyelash in my eye and blink and it's gone where does it go? Do I have a build up of junk behind my eyeballs?
Junk can't get behind your eyeballs barring trauma, there's a membrane preventing that. In general material is flushed from your eyes by tears and/or blinking action.Most small particles that get on your eye will be pushed to the lower eyelid when you blink, then make their way to the corners from thereIt goes into a duct that funnels into your nasopharangeal tract. Basically when you blink, your eyes push any kind of foreign objects to the corner where they pass through a duct and ultimately either run out your nose in the form of snot, or it goes down your throat when you swallow salivaI 've had many contact lenses get lost in what seems like "the back of my eye." If I rub my eyes too hard, I'll see my lens drift to the side of my eye and in a desperate attempt to get it back, I end up pushing it back further. Believe me, I 'd know if those lenses came out of the corner of my eye. They don't. Where do they go?Usually when you blink and that gets an eyelash out of your eye the eyelash was still anchored to your eyelid. The far end is what gets in your eye and irritates it, and a blink or a rub snaps it back into its usual place.
Why big banks are considered evil.
Imagine your parents are saving up money to buy a house. The house is very expensive and your parents don't have all the money that is needed at the moment to pay for the house. The bank says, oh thats ok, you just pay us a little bit every month until you make the full payment and you can move in right now. You don't even have to pay us anything for the first three months. Your parents say "Wow! Thats great" and trust the bank to do this. This debt that your parents pay to the bank every month is called a mortgage. The standard length for a mortgage in the US is about 30 years. However, the bank purposely didn't tell your parents that the money they must pay each month will get bigger and bigger. Also the bank will charge your parents something called interest. Interest is more money that your parents have to pay the bank for borrowing their money. So even though the house may have only been worth 200,000 dollars, the bank can add on fees for borrowing that may mean your parents have to end up paying 300,000 dollars to the bank. Your parents think that they would pay the same amount of interest every month, but the interest goes up every month too. The bank intentionally does not tell your parents about this and they have to work very hard and pay a lot more money because the bank was being mean and they trusted the bank too much. If your parents\' piggy bank runs dry, and they can no longer pay the bank. The bank will kick you out of your house and you will no longer have a place to live. All because the agent for the bank was acting very friendly, but tricked them into signing a piece of paper that would make them lose thousands. This is one of the main reasons why many people in the united states hate banks and think they are mean and want to steal their hard-earned money.
Why should I hate the 1%?
You shouldn't hate them, people who do are just jealous. I'm not saying they don't have unfair advantages; I'm just saying if you were given the choice you'd be rich too.
What happens when system32 is deleted?
> what happens to the computer Nothing at all will happen to the computer, your installation of windows may stop working though and you'll need to either repair or reinstall it.
How do insurance companies gain profit?
By giving away less money than they charge. It's as simple as that. They charge you for the risk you wish to cover, and it's reasonably certain that over a long period you will spend more on insurance than you will ever receive in payouts. Obviously some people will go the other way, but they'll be in the minority. It's the same as gambling. They're betting you won't have an accident, and you're betting you will. In the end, the house always win because they control the odds.
When hackers steal money, where do they send the money?
Different hackers will do different things, I'm sure, but the cases I hear about are more about credit card fraud than redirecting funds. Hackers will get credit card numbers with codes and use those to purchase things. The cases I know about involved buying sporting goods and gift cards, presumably because they are easy to re-sell.
If protests rarely work why do thousands of people protest?
The idea that "protests never work" is flawed. Hell, civil rights in America came largely from "protests". Sometimes it's the only option people have to fight entrenched systemsIn France it works every single time. Lst one was Uber strike. Suddenly thr lawmakers decided Uber was illegal
Why does older furniture hold up so well when modern furniture seems to break in a few years?
The modern furniture you're seeing is cheap modern furniture. There's modern furniture that holds up well, but it costs a lot more. Why wasn't there cheap furniture years ago? There was. But you don't see it any more, because none of it survived to this day -- *because it was cheap*.
Why do people ask for advice, yet get angry when it's given?
Many times the advice isn't what we want to hear, and humans have a strong bias in favor of information that agrees with what we already know. That's also why politics and religion can be so divisive.
Why does China feel the need to censor the internet?
The CCP is ultra sensitive to criticism and the power of technology to cause disruption. They pragmatically understand that they need to keep a lid on dissent. The lesson they learned form Tiananmen Square was that free association and unfettered access to information would be bad for their regime - and in their view - for China. People in the PRC are not used to having complete, unfettered access to information so the censorship causes less concern than it would in a liberal western countryInformation is power. Only the government is allowed to have power in China. More specifically, the news that the government in China tells the people is vastly different than reality. If the truth got out, the people would know the government was lying.Do remember that most societies are rooted in a history of the group in power totally dominating the rest of the people, with this eventually being tempered by traditions or religious sensibilities. America is one of the few societies that has a history in which people saw each other as existing against common difficulties, which we got from our frontier heritage. The idea that political power is secured by eliminating dissenters never took root here, but China has a long history of conquest and reconquest, with each group destroying books and intellectuals when they came in. Usually government attempting to control the thoughts of the people is the rule, rather than the exception. The CCP is a particularly bad example, because they have traditions of paranoia. Ever since they were betrayed by the GMD in the early 20th century, they have had a tendency to panick at all internal dissent, seeing it as a sign of imminent betrayal. They are also looking at the USSR. When the smaller countries realized how weak Russia was compared to what they had thought, rebellion broke out left and right. The shift towards Capitalism has really left the CCP with no good reason why they should be in charge, and they don't want the people to get ideas.
What is the deal with fetishes?
Our brains are pattern-seeking organs which create and strengthen associations between things. Consider Pavlov's dogs; they were trained to associate the sound of a bell with getting fed, and their brain commanded salivation even though it was outside their conscious control. Training is just intentional manipulation of a property at work every day, where we learn how the world works by recognizing associations and strengthening the neural pathways connecting them. Fetishes come about the same way, where certain things appeal to people and enhance their sexual pleasure. How the connection gets made might be convoluted and difficult to determine, but in the end the connection made is likely not under conscious control.
What would happen if the president divorced the first lady?
The First Lady is not a legally-defined position, so it would in theory be just like any other divorce. Under the law as it currently stands, she would not be automatically entitled to Secret Service protection though the President could and probably would request it for her just as a security measure. In terms of alimony or splitting of assets or whatever, that would be determined by the family court of whatever jurisdiction finalized the divorce. As for who would become "First Lady", well, since there is no such official position, it would basically be whomever the President chose. In the past, unmarried or widowed Presidents have used sisters or nieces as First Ladies. In theory there could simply be no First Lady anymore.We actually had that happening in France in François Hollande's current term. He was caught cheating on the first lady with an actress. The first lady left him and publish a revenge book revealing all his dirty secrets. Now, we don't have any first lady. Fun times :)", 'She would no longer be the first lady. According to tradition a female relative would take over the position, unless the president wanted her to continue acting in the position. There have been presidents who have had sisters acting as first lady before. There has not been a divorce while in office yet. It really would be up to the president, though I doubt any president would have a divorce while in office unless it was politically necessary ', "I think Reagan was the only president to ever get a divorce, it was 20-30 years before being elected pres tho. There's been a lot of infidelity though, from Jefferson to Kennedy to FDR, etc. With the way the country's divided right now and with the 24/7 tabloid/news cycle we got going on, if a president did get divorced in office, I'm pretty sure it would be a non-stop shit show for months and months.
Abductive, Inductive and Deductive Reasoning?
**Deductive reasoning** is where you draw specific conclusions from a set of general principles. If I know that all dogs have tails, and my friend has a dog, I can deduce that my friend's dog has a tail. **Inductive reasoning** is sort of the opposite, where you come to a general conclusion based on a set of facts in front of you, usually looking at probability. If I know that every dog I have ever seen has a tail, I can presume that most dogs have tails, as a general rule. **Abductive reasoning** is a little screwier. It's basically a reasoned assumption based on the set of facts before you. So if my dog is wet, it's been raining outside, and my dog has been playing outside, I can presume through abductive reasoning that my dog is wet because of the rain. It might not be true - she might have just spilled a glass of water on top of herself - but it's the most reasonable assumption given a set of facts.
IXPs like the Verizon building in NYC, and how it applies to transcontinental fiber, "backbone of internet" concept, etc.
If you're an Internet Service Provider you need to be able to get your clients\' traffic out to anywhere on the internet, so you have two options - either you carry it yourself to somewhere you can hand it off to the ISP of the place it needs to go, or you pay a bigger provider to take it there for you. ISPs are conceptually divided up into \'Tiers\', ISPs that primarily provide the long-haul transport services are called [Tier 1] providers, they sell "Transit" to Tier 2/3 ISPs. Tier 2 ISPs are smaller organisations who themselves sell transit to Tier 3 ISPs, and pay Tier 1 providers to move their data to places they can't reach. The difference between a Tier 2 and Tier 3 ISP is Tier 2 providers participate in what's called \'peering\', where they directly connect to other Tier 2 ISPs to avoid paying a T1 to carry traffic that they themselves are capable of delivering directly, T3 ISPs only buy transit. Tier 1 providers also peer with each other for similar reasons. The places where these ISPs\' networks meet up to interconnect are Internet Exchange Points. Let's imagine you're in the US and you want to talk to a server in Europe, if your ISP doesn't have it's own lines running across the atlantic your traffic will have to go through a Tier 1 or Tier 2 provider who does, so it'll have to go through an exchange point in the US to a provider who'll carry it across the pond, and then possibly again on the other end to the ISP of the server you want to talk to. Transcontinental fibre isn't necessary, if your traffic is staying within the US but going to a different ISP it could still have to get transit across the country or at least get handed over to the other ISP somewhere along the way.
Why is it that we laugh more when we watch a movie with others than we do when we watch the movie alone?
Laughing is primarily a social signal that is used to indicate solidarity with others. If we are laughing along with other people, it indicates to them that we are similar to them . Robert Provines is a psychologist who has studied laughter and found that people are far more likely to smile or talk when alone than they are to laugh. The reason laughter is a good social signal is because people can tell when you are faking it , so an honest sounding laugh is a good signal to someone that you like them.I know one thing, if I find a movie hilarious I *may* laugh even when watching alone. But, if I have already seen it and am showing it to a friend, I am going to laugh more and more often. Why? Probably because I already found it humerous, but also because I am experiencing the movie for the first time through their eyes and their reactions. In other words, their joy becomes your joy as well.I don't think this is a universal phenomenon. I personally tend to laugh more at things when I'm on my own.
What does "quartz" mean when it comes to watches?
Modern quartz watches use a tiny tuning fork made of quartz which is tuned to vibrate at a very specific frequency, which is counted to keep time. Quartz is used because it is piezoelectric which means it can be made to vibrate with a tiny electric current.
What is "scientific whaling"
The big data point collected has to do with whale feeding habits, and whale ecology in general. By sampling the population, Japanese researchers have collected a large amount of data about whale feeding, and more broadly about the availability of krill and where the line is between underpopulation and overpopulation. This has been controversial, to say the least.Perhaps contrary to what Imhtpsnvsbl said, my understanding has always been that it's fairly well agreed that Japanese whalers aren't really studying much at all, and that whaling is something that's more important to Japanese politics than it is to science or even to Japanese meat markets.
What is 'credit' and why is it so necessary in today's society?
Credit is borrowing from a rich person to pay for something expensive that you don't have the cash for right now. The rich person gives you the large amount of money, and in turn you pay a fee to the person for using their money to buy the expensive item. Credit is necessary because the majority of us don't have 200,000 dollars to pay for a house in cash, or 25,000 for a car, or 200,000 for college. Being a cool borrower . Not opening and closes lots of credit accounts.) makes you cool in the eyes of companies that watch what you purchase . Those companies then vouch for you to the banks saying your cool to get money to borrow.
What are people referring to when they say "The Church"
It is the Christian religion, normally referencing either the dominant philosophies held by most denominations or "all" of christianity, or they are referencing the specific doctrine of the church being talked about in the conversation or the dominant denomination of the region they life in. Context of the conversation is what will tell you which they are referring toThe Church , used to refer specifically to the Catholic Church . If the Catholic Church isn't what is being referred to when you hear "the church" ), you will probably need more context from wherever you're hearing the phraseThe Catholic church. Commonly referred to as "The Church", due to it being the oldest and best established. It typically is referring specifically to the Vatican .
What would happen if someone dies in space without a suit?
It depends where you are. If you're in the solar system, you're body would swell from radiation, and you 'd freeze a very long time from when you die. People often think you freeze instantly. This is false as there is nothing in space to "steal" your body heat, like air on EarthTheyd just slowly suffocate due to lack of oxygen and their skin would begin to frosbite. No eye popping or exploding, at most the water on their eyes, skin and mouth would instantly turn to a gas state.
Why does the cuban government tolerate guantanamo on their territory? Especially if one considers their bad relations in the past.
Cuba had been trying to get independence from Spain for most of the late 19th Century. As part of the Spanish-American War, the US encouraged them to rebel. After the war, the US controlled Cuba and considered annexing it, but instead installed a government and constitution friendly to the US. One of the early agreements the US made with the government was to lease Guantanamo Bay indefinitely. In 1959, Fidel Castro came to power in a communist government unfriendly to the US. The US considered their lease to still be in force, and continued to send payments. They have used the fact that Castro accepted on of the payments as tacit agreement to the lease. Cuba would like nothing better than to kick the US out of Guantanamo Bay, but lacks the military power and legal authority to do so. The international community in general recognizes the US claim, at least to the extent they would not intefere if the US took military action against a Cuban attackWhat are they going to do about it? They leased it to us.
how do we know the taste of highly poisonous substances? Or do we have no idea about it?
"Highly poisonous" is a broad category. If it's so poisonous that once you taste it, even if you spit it out, you're dead, then the taste wouldn't matter to help prevent you from dying. On the other hand, if it's deadly only if swallowed, but you won't die if you taste it and spit it out, then standard evolution processes would favour those animals who had taste receptors that could distinguish the taste of that particular poisonPeople don't generally know the inheret taste of "poison," but people are evolved to dislike the taste of common things that will kill them because people who like their tastes will usually be more likely to die from them and fail to pass on the genes for "poison tastes good" Since it became advantageous to dislike the taste of something that might kill you, people are adapted to dislike the taste of these chemicals.I couldn't find your answer specifically but this was really interesting: _URL_0_

Why are we more likely to have a heat stroke if we've had one before?
In a nutshell, it has to do with heat tolerance. In Construction we learn about it as acclimation. Your body needs time to adapt to a hot environment, and so the general rule of thumb is small doses of exposure to excessive heat and then gradually your body can tolerate more. Every season reacclimation is needed but not as often do you see people reacclimatizing, they expect to be able to handle what they were able to last season. For those who have had a heat stroke before, it depends on how fast they cooled down. The faster you fix it, the more likely a full recovery. However, if thermoregulation was damaged from prolonged exposure, then the body can develop heat intolerance. Heat intolerance is similar to lactose intolerance, or any bodily intolerance. Even heat intolerance should heal itself within a year at the longest, but having a stroke within the middle of a hot season leads to complications because the body is still experiencing intolerance, leading to a higher likelihood of having another heatstroke and causing more damage. Also things like dehydration factor in as well leading to a higher risk. There’s generally a reason someone suffered a heatstroke in the first place and those reasons are likely to reoccur. Source: am a student in Civil Engineering and OSHA trained There isn’t a lot of research into it being a genetics thing, but it could be possible.Anyone can have a heat stroke under extreme enough conditions. But it is unlikely that you were experiencing world-record conditions when you had a heat stroke. Especially if you were around other people in the same conditions who didn't have one. It is far more likely you were in only slightly extreme conditions, and had a heat stroke because you are more susceptible to them than other people are. Whatever made you susceptible the first time is likely still there, making you more susceptible in the future as well.
Why is it better to have more but smaller cylinders in an engine, rather than fewer larger ones?
The stroke limits the effective rotation speed of the engine: The rate at which air flows into the cylinder depends on the crossection of the valves. If you increase the stroke length, you increase the size of the cylinder, and with it the amount of air that needs to flow in it - but since you can't just increase valve size unless you also increase the bore , the stream of air flowing into the cylinder remains constant. So it takes more time to fill a larger cylinder with air, which limits how fast the engine can turn. So for a very large single cylinder engine, you'd either have to reduce RPM, which reduces power output, or use very flat cylinders, which is detrimental to clean and efficient combustion. In addition to that, only diesel engines work with very large cylinders, since combustion proceeds evenly within the combustion chamber. In gas engines, combustion starts at the spark plug and then moves outside - and this only works smoothly with small cylinders. What also factors into this is the rather compact build of inline or v engines, which are approximately cuboid. A single cylinder engine has a very odd shape, which would take up a lot of space under the hood.
Isn't lobbying just a legalized form of corruption?
Lobbying is trying to convince elected officials to change the laws in a way that is beneficial to your interests. Not only is that not corruption, but the right to petition for a redress of grievances is so important that it's right there in the First Amendment, along with freedom of the press and religion. If you've ever sent an email to a congressman asking them to vote YES or NO on something, then you've lobbied too.
How come mosquitoes are useless to the ecosystem as a whole?
No, eliminating anything could have potential impact. What has been found with mosquitos so far is that we don't know of any serious impact on any ecosystem that wouldn't be filled by other species. That doesn't mean there isn't one, just that we don't know of one. As far as other parasites go, some very peacefully coexist - the question is really whether the negative impact of their existence versus removing them. [This is an article about the study the person making the comment was probably referring to.]
How does oil lubricate an engine without combusting or contaminating the fuel?
The fuel is sprayed into the cylinders, where it mixes with air, is compressed, combusted and then evacuated out. Engine oil is not put directly into the cylinders. It gets pumped and directed to just about all of the other internal components though. What separates the inside of the cylinder from the rest of the inside of the engine, is a set of piston rings. And actually, a tiny bit of the engine oil gets in between the piston rings and the walls of the cylinders and lubricates that movement. As I understand it, a tiny bit of the oil does get caught up with the combustion of the fuel. An engine has an oil consumption rate. So even if you don't have any leaks, you eventually do have to add oil. It's usually pretty low and most people simply get to an oil change interval before actually having to add oil. But some engines can go though oil much faster and will need to be topped up regularly.
Why are Neanderthals always drawn with huge noses?
Because the size of the nasal opening is large, so it is inferred that the nose itself would be large as well.
Why doesn't everybody come together and vote third party?
People are afraid of wasting their vote on a candidate who won't get many votes, and thus cannot win. It's one of those situations where everyone stands in a circle and says "I'll vote 3rd party if you do", and the other person says "I promise I will. Together we can make a difference!" Then everyone secretly decides they don't trust each other, and votes 2 party.1) A lot of us don't want to vote third party. 2) We don't agree on the same third parties. 3) The winner take all system within most countries makes it very difficult to have successful third parties.[CGP Grey does a great job of explaining] the two-party system and why it ends up the way it does.If a third party emerged that was to the left of the democratic party and we had three presidential candidates the election could look something like this. Republicans get 40% of vote Democrats get 35% of vote Far Lefties get 25% of vote By having two parties that both lean left, they have split the left's vote. Now even though only 40% of the people wanted a right wing candidate and 60% wanted a left wing candidate they have elected a right wing leader. Having a third party hurt the people who share their ideologies. EDIT: formatting
Why do Americans feel the need to remake British TV shows?
The same reason British television tries to adapt American tv shows. For example: In With The Flynn's, Brighton Belle's, Love By You, Nobody's Perfect, Upper Hand, Days like These, Married for Life and so on. It's cheaper and you have an already successful model to build on.
Why are chemicals in glowsticks considered harmful, but the ones in a glow in the dark wristband are not?
To say it in one breath: Glow-in-the-dark items react against previous exposure to light, whereas glow sticks rely on the chemical reaction of mixing two prepackaged chemicals. That's why you have to "break" glow sticks in order to mix the two otherwise separately stored chemicals.
Why do hydrogen atoms possess radioactive capabilities in space?
It isn't that they take on radioactive capabilities. It is that when something is traveling really fast, the kinetic energy increases. So, when it hits something, it can cause a lot of energy release. In this case, the basic equation is something like KE = 1/2mvv . where 'v' is velocity. Well thanks to relativity, when two objects collide, you don't know which one was moving and which one was standing still .so the kinetic energy is there! A single hydrogen atom has a lot of kinetic energy when one or the other is near the speed of light!
How can some criminals show their face on television, and then still come back for a second season?
I believe it's because you cannot prove that what they're doing is actually creating illegal products. It's similar to how you see videos of famous musicians or artists smoking marijuana but they never get prosecuted for doing it. It's also similar to when you watch true life on MTV and those people do harder drugs.
Why do different colors evoke certain emotions in people? (e.g. red and anger, yellow and hunger)
They don't, by-and-large. It's a cultural myth that colors alter moods or cognitive function in any meaningful way outside of the placebo effect. Red is "anger and hate" in the USA , "joy and luck" in China, "love and passion" in Russia , "purity and spirituality" in India, or "death" in some African nations. How can one color evoke all those emotions all over the world? It simply can't. It's just a cultural association that elicits the placebo effect.Its not that the color themselves evoke the emotion its the conditioning, I'm sure based on color florist don't see red anger but red passion and yellow joy sunshine thats why emoji happy face stickers back in the 90s was yellow. Colors evoke emotions strongly attached to that color like a placebo pill your told bulls hate red, oh yeah RED ANGER MAD.
Why does hot water soothe a bug bite?
It seems to be linked to the nervous response. There are a number of different ideas out there. One claims that it's a process of denaturing proteins that would cause the itch. But that explanation wouldn't portray very good proteins. We would have proteins failing every time we take a shower. Another claims that it somehow "cancels" the mosquito saliva. But by that point the anti-coagulants injected by the mosquito are no where near the surface of your skin. The most reasonable hypothesis is that it confuses or overloads your nervous system. Instead of sending a signal for \'itch\', your neurons send the signal for \'warmth\' or for \'pain\'. So it's probably that it messes with your nerves a bit.The explanation I've read is that the heat increases the release of the histamines that cause itching. They're released all at once, until they're depleted in that area. Supposedly, that's why the itch may actually feel worse for a bit as it's under the hot water. The hot water also dilates blood vessels in the area, carrying those histamines away. I read somewhere that it can take an hour or so for more histamines to build up in the skin. Grain of salt, though, this is just what I saw somewhere.
How do cities that offer free wi-fi not run the internet providers out of business? And if they do, how do they get away with it?
Free wifi is generally fast enough to do email and shop online, but not good enough to stream movies, play games, or download large files in a timely manner. Many people are willing to pay extra for better speeds.
How do stomach acids & enzymes break down foods exactly enough to be useful nutrients and amino acids, but not enough to break *those* down into unusable molecules and elements?
Because although acid is necessary for the reactions to take place efficiently, food digestion is actually driven by enzymes, catalysts that facilitate specific reactions and not others. Digestive enzymes facilitate the breakdown of proteins to amino acids and complex carbohydrates to sugars, but they do not facilitate the further breakdown of those "building blocks". Breaking down the building blocks requires very different reactions than breaking apart the large molecules, and would require very different enzymes to happen.Because they can't realistically get any smaller than their useful variations. The stuff we use is basically the base building block of every biological organism or material. For example: We use iron in its smallest form, a single atom of Fe, in our red blood cells. We use amino acids in their base form, in proteins. We use fatty acids in their base form, in fat. Most of the other materials are just their base atoms or ions, such as Na, K, Ca, etc. The digestive enzymes are highly specific and only break down the molecules they're designed to break down, such as proteins and fatty acids. The acid in our stomach doesn't really damage our food, it just makes it a bit more susceptible to digestion and kills some organisms that happen to come down with it.
Microchips, how do they work?
Well, a CPU is mainly a collection of billions of tiny parts known as transistors, all interconnected with wires to form logic circuits. A transistor can be described as an electronic switch. It operates like a normal switch does, it has an input, output, and switch, but the difference here is that the switch is an electrical signal, when the switch wire is powered, the electricity is allowed to pass from the input to the output. Anyways, with this, we can make logic circuits with electricity which can do math. [Here are a few basic ones in a nice little PDF] but these basic ones can be stacked together to make them super complex and able to do all sorts of math. Billions of them make up CPUs Now, these transistors are super tiny, modern ones only consist of a few hundred atoms. They are made tiny so that more can be packed together to make more complex CPUs that can do more complex math. They are made using a technique known as photolithography, which is a fancy word for them coating silicon on a special type of chemical and then shining a UV light at it through a stencil, which prints the pattern for the CPU onto the silicon.
Why do we get bored of things that were fun ?(eg: video games, sports)
This is one of the mechanisms that influences humans to seek out novelty. Your brain cannot afford to only reward one behavior forever, or you would waste away in front of your computer. Getting bored is a way to keep you from getting stuck in that kind of loop. I can't find any information on the physiological mechanisms at play, but addiction research shows that most stimuli become less rewarding over time.
ELI5: Why do certain noises/textures (e.g. a fork scraping on a plate, the feeling of velvet) provide such an unpleasant sensation?
For me it’s certain cloth and towels.. dry friction makes a squeaking noise and I lose it. The thought of biting down on a towel makes me hair stand up on end. For my mother, it’s certain wood textures.. Cutting boards, wooden spoons, etc. I don’t know the accurate answer but it probably has to do with sensory overload.
How a country "Annex" a portion of another country without it's permission?
It's illegal in every domestic and international definition. But what do you do? Start a war with Russia?
How did brand names(such as Band-Aid or Chapstick) become the unofficial name of that product?
It's usually because a particular brand achieves a very high level of market penetration and becomes synonymous with a product.
What happens to deceased soldiers that are left behind after a battle?
For Marines we are trained to leave no man behind and many Marines have gone back and drug the bodies of the fallen into friendly territory. Also there is some respect paid to the dead and allowing retirval from both side, not always the case and some never return. This is what the POW/MIA is about. Since there is no body we don't know if they are prisoners or dead or just lost.
Why are there faces carved into Mount Rushmore? Who are these figures and what must they have achieved in order to be put on there?
Washington - first president Jefferson - drafted the Declaration of Independence Roosevelt - major reformist, set up national parks and other big deals Lincoln - freed the slaves All four were very significant presidents. *edit-* Theodore Roosevelt also set up the country to come out of the great depression with The New Deal. I wasn't 100% at first if it was him or his cousin, Franklin D. Roosevelt. *edit again-* My initial doubts were correct. Fuck me.
What is P2P network? I know it has already been answered here but I still don't get some basic things. Details below.
What you're asking for is called [IP routing] and is one of the fundamental structure of the internet as we know it today. The basics of it is everything with an ethernet or WiFi adapter keeps a routing table which tells them if I want to access X address, send the packet to Y because he know how to get to X. In case they don't know, they have a default address to send it to and this address will do the same process. To take your example, you PC never know where your friend is, but it knows someone that knows someone that know where your friend is.
How is The Pirate Bay still up and running when all the founders are in prison?
To answer the latter part of your question: a little while back TPB moved to a highly distributed cloud architecture. You can't confiscate a server that doesn't physically exist, and thanks to the way they designed the system nobody knows which cloud providers are actually hosting the servers .
What is the purpose of pre-cum?
It also "cleans the tubes" before sex, adjusts the PH for the little swimmers, and keeps them from gumming things up on the way_URL_0_ > Pre-ejaculate is believed to function as a lubricant and an acid neutralizer. and > Acidic environments are hostile to sperm. Pre-ejaculate neutralizes residual acidity in the urethra caused by urine, creating a more favorable environment for the passage of sperm. The vagina is normally acidic, so the deposit of pre-ejaculate before the emission of semen may change the vaginal environment to promote sperm survival.[6] > Pre-ejaculate also acts as a lubricant during sexual activity,[6] and plays a role in semen coagulation.[6]
Why can't Greece just say 'screw it' and go back to using the Drachma?
Because being part of the EuroZone has all sorts of trade benefits. If Greece switched to the Drachma, the Drachma's value would obviously be a tiny fraction of the Euro. For the Greeks themselves, if they switched it would be expensive for them to import goods since the Drachma would hold much less value than the Euro. That means everything for them will cost a lot more. Heavy inflation would occur, and their domestic economy would be wiped out even more so than it is. The Euro is at least more stable, since it's a currency that represents not only Greece but the EuroZone as a whole.
How do baseball players catch an inbounded ball with their ungloved hand without breaking their hand?
I don't know anything about baseball, but I can answer in terms of cricket, where the ball is slightly heavier, harder and fielders don't have any gloves. Essentially when you catch the ball, you're not stopping the ball dead, you allow the momentum to carry your hand back slightly, or you already have your hands moving in a slight backwards direction to decrease the impact. Similarly, you don't catch a ball with your hand flat, your hand is cupped and loose around it, spreading out the impact this makes a big difference. Try punching the palm of your hand, once with a stiff rigid receiving hand, and the other with a relaxed slightly cupped hand. You'll notice there's quite a big difference. Obviously sometimes you mess it up and broken fingers are relatively common in cricket.
The difference between mass and weight
Your mass is a given quantity regardless of where you are. Its how much "stuff" you are made of. Weight is how gravity acts on your mass so you weigh less on the moon because there is less gravity but your mass is the same anywhere you go in the universe.In space, you can let go of a brick and it'll not drop painfully onto your foot. It has no weight. However, were you to throw it at your foot, it'd still hurt, because it has mass.
Does anyone actually work "9 to 5"? If so, why doesn't the company require the employee to put in 40 hours of work each week?
Paid lunches are a real thing you know9-5 are the traditional hours businesses are open, also known as first shift or day shift. So 9-5 means an employee covers those hours while the business is open. They may come in a little early or stay a little late to perform tasks while the business is closed, but they primary responsibility is to support the 9-5 business cycle. And more generally, it refers to anyone who works the normal M-F day shift, regardless of when the business is actually openI work 9-5 and I generally eat at my deskI worked for a place that had you come in at 3 and, on paper, you left at 11:30. However, the next person would come in at 11 so the two of you could cross talk if necessary. Nothing to talk about? Go home "early". Today I work for a place that basically says, "show up whenever, but work 8 hours" excluding time for an unpaid lunch. So if I really felt like it I could show up at 7, eat at my desk and leave at 3, or 8 to 4, give or take. Pretty nice to have that kind of flexibility over my schedule but then again that's a perk of being the only guy in your departmentI have worked two full time jobs in my life. The first was 8-5, with one hour for lunch. This resulted in 40 hour work weeks. The second is supposed to be 8:30-5, with 30 minutes for lunch. This too would result in a 40 hour work week. Based on my two experiences, I would say that it is impossible to work 9-5 and also be considered a full-time employee. Perhaps those who work 9-5 are not considered full-time, which also is beneficial to the company as they are then not required to provide full-time benefits to those employees9 to 5 would be 8 hours. 8 hours a day times 5 days a week is 40 hours a week. What was the question again?
What is wifi and how does it magically give my device access to the internet?
Electronic waves. According to the frequency your computer interprets it as an open or closed signal . From then on it's just binary programming.
If you lose one of your five senses, do the others actually grow stronger, and if they do how is that possible?
It's not that the senses get stronger in an absolute sense. Someone who is blind doesn't gain the ability to hear sounds that would be too soft for a sighted person. It's a matter of attention and processing in the brain. A blind person may notice the soft sound that a sighted person would ignore because of how soft it is, not because their sense of hearing is stronger, but because more of their brain is focused on processing the information being gathered by their sense of hearing.
when comedians have their own tv shows, why do they need writers?
If its a weekly show, even if its only half an hour, there's an amazing amount of work that needs to happen each and every week. The writing for each episode can only happen in 1-2 days - since the writing will dictate if there's any special props, sets, wardrobe, extras etc. that are required, special music, licensing/rights if there's to be a clip shown or played. Those things just don't show up overnight. So the script has to be in close to final form days before the show is recorded. That, and to come up with truly top notch stuff, consistently week after week? Thats hard. Podcasts are a little different. You're not expecting them to bring their A-game for an hour twice weekly if they want to drone on about how the barista at Starbucks spelled their name wrong and you're willing to listen that's fine. But that's not the kind of content that can fill a weekly show that is broadcast on a major network or streaming platform and keep the audience coming back week after week or nightly. e.g. Seth Meyers is a funny guy and I'm loving his weeknight show. But to consistently come up with a funny 5-10 minute monologue plus another 10-15 minutes for "A Closer Look" . *every night* That's too much for any person. Try it yourself. Go and write a 10 minute presentation. Keep track of all the time you spend polishing it and practicing it. I bet it will take several hours. Now try for an hour long presentation it will be days/weeks of effort.
How does carbon and isotopic dating work?
Carbon dating works for things that were once alive, but then died. There is a special kind of carbon called Carbon-14 that is short lived but gets constantly created in our atmosphere. Basically as long as something is alive and breathing it keeps a constant level of this carbon-14. Once it dies, the carbon-14 begins to decay. By measuring the ratio of carbon-14 still around, you can guess when it died. For things like wooden tools and paper they assume they were made shortly after the tree was chopped downI'm not an expert at this, but there are two isotopes that we measure; C12 and C14. When an organism is alive these stay in the same proportions, but when an organism dies the organism stopt breathing in fresh air so the C atoms are trapped in the body. Because C14 is radioactive and "transforms" into N14 the amount of C14 decreases. Using the proportions of C14 to C12 a year of death can be determined', "carbon-14 is in just about every living thing on earth. It also happens to be radioactive, which mean that is has a half life . Carbon 14's half life is about 5,730 years, making the formula for how much C-14 is left after x years:original amount*) Carbon dating becomes inaccurate after a certain point because there isn't enough C-14 to measure, and the percent error of the calculation magnifies as the number of half lives a fossil exhibits increase.
What is the Bilderberg?
It's a group of some of the most infuental people in the world that pretty much nothing is known about publicly. It supposedly works like a club, with occasional meetings with discussions covering various crucial economical and sociological issues. The lack of media coverage for the group resulted in a shitload of conspiracy theories about it, to the point where some people actually believe that the Bilderberg chairman is a jewish reptilian.He's not REALLY jewish though.I was curious about this as well. From doing minor searching, what i can gather is that it originally was made to promote the understanding between the cultures of Western Europe and America. As to what they do today, im not sure of what they do. They might just be a club for important people. Im going off of Wikipedia. Here is the link : _URL_0_
How do animals avoid inbreeding in the wild?
Exact way varies by species. For example lions, elephants, and others often drive away the males from the family group. Then during breeding time, generally only the dominant male in the area has the opportunity to breed with the group. This reduces the odds of inbreeding. More importantly, it reduces the odds of inbreeding over multiple generations. In breeding for 1 generation has a fairly low risk of genetic problems, it's inbreeding over multiple generations that causes problems.Adding on to what /u/Snewzie, phermones can often help animals determine/decide which other animals to breed with. There was a study done in which people were asked to smell and categorize sweat by smell. The researchers fond correlation that and individual is likely to find the sweat of their siblings to smell bad, whereas the sweat of another individual to be attractive. If I can find the study, I will link it.
When it smells like rain, what am I actually smelling?
Most likely [petrichor], the smell of rain on dry soil. If it's a thunderstorm, it could also be ozone, which forms when the lightning essentially fuses oxygen together.
How cloud storage systems (email, Google drive, Onedrive) don't run out of storage
The very simple answer is that they can always add mode storage as usage grows. Same way you can add storage to your home systemCloud providers run specialized storage software that allows for any amount of data to be served by clusters of many, many harddrives. The software automatically keeps several copies of the data spread across many of the harddrives so one HD failure is not catastrophic. The software automatically "balances" the data as needed allowing for HD replacement and addition. Some of the other replies here show you the vast amount of harddrives that are available. Drives are failing all the time and have to be replaced. Also, new drives are added frequently. Often, the new harddrives are much bigger in capacity than the older drives that they replace.
If planets like Neptune emit light, why do they have a "dark side" facing away from the Sun?
The amount of light they emit is incredibly small, compared to what comes in from the sun. It's also primarily in the infra-red part of the spectrum, so human eyes can't detect it.[Like Jupiter and Saturn, Uranus emits more heat than it recieves from the Sun, but just barely---about the same as that emitted by the Earth.] So Neptune does radiate more energy than it receives. But the sun still shines on it. So there is a dark side away from the sun. It does have a heat signature which is detected.
What does "Installing" on a computer actually do?
1. It copies the files to the correct location. Sometimes, different files for the same program have to be in different locations. 2. It checks if all of the shared components it needs are installed, copies the files over if they aren't, and registers the ones it copied over with the operating system so it knows in the future that it's installed. 3. It registers itself with the operating system- it lets it know where all the files are , where the executable is , and what file types it can open .
Why do we have to get a commercial driver license to drive a bus or semi, but not motor homes, which are almost just as large?
1. You don't have paying customers on a motor home .2. It's the "almost" part that makes it legal. There has to be some size limit, and so they build right up to that limit, which I believe is something like 40ft in length, and 26,000 GVWR. I moved from western NYS to Denver, CO a few years ago, and those were the limits on the largest moving truck I could rent with the drivers license I have.The answer is in your question. You need a commercial license to drive a truck or a bus because your driving is for commerce. You are making money off that. You don't need a commercial license to drive a huge RV because it's a private vehicle. If you were to offer people tours or something you'd need a commercial license. And a chauffeurs endorsement.
How do so many airlines stay afloat in America?
The country is very large, with the cities so far apart that train service is too slow. So people want to fly a lot. The country is immensely wealthy, with a GDP per person of well over $50,000 per year, and hundreds of million of people. So a lot of people can afford to fly.
What causes your nose to be runny instead of stuffy when you have a cold?
A reason I could give is that the common cold is not one virus; it's a bunch of different viruses with similar symptoms. This is also why some colds are worse than others. Because of this, certain viruses give off different symptoms but they are also classified under a cold, meaning that, for example, although you have Virus A with coughing and a runny nose and Virus B with coughing and a STUFFY nose, they'll still be classified as one sickness due to it's quite similar symptoms and methods of treatment. TL;DR the cold is caused by a bunch of different viruses with similar but not the same symptoms, making each cold a little different in strength, such as the runniness or stuffiness of your nosr
Why does my immune system fight so intelligently against most malignant illness, but go full retard with benign allergens?
Mast cells line much of your body's inner skin lining. When confronted with a puncture or other allergen, they release histamine that causes the inflammation reaction along with blood vessel dilation and bronchial constriction.Sometimes the antibodies that normal immune cells use to identify antigens accidentally get lodged in these mast cells. If this happens all over the body or especially near the respiratory system, the presence of these specific antigens will trigger them all to release histamine, causing widespread allergic reaction. Someone please correct me if I'm wrong, I'm just a high school biology student ;_;
When I use my debit card at McDonald's, I don't need to enter my pin or sign. Why do I sometimes have to enter my pin and sometimes have to sign?
If they run your debit card as if it were a credit card transaction, they don't need you to enter your pin. And often, for smaller transactions, stores feel that the time spent on getting the customer's signature on a credit card transaction isn't worth it, since while the customer could protest the charge and go through the hassle of having it reversed if there is no proof of signature, it's not really worth it for something small.
Cologne, After shave, deodorant? ?
Cologne is how perfume is marketed for men. Aftershave is for preventing infections after shaving. It may have ingredients that numb skin a bit and almost all have some fragrance. Deodorant is for killing body odour caused by bacteria that eats sweat. Antiperspirant is a type of deodorant, that clogs sweat glands. So basically - cologne for going out, aftershave after shaving and deodorant if you expect to be sweaty.

how does the new internet bill that Reddit hates so much work? Will I actually be able to call and request any person's web history? How will companies take advantage of this?
No, definitely not. Basically, companies can collect data on you either to sell or for their own use. Other companies can buy this data. It helps them get insight in trends for their users. While good for the business, that means your personal life is being used for monetary gain. That's what happens with grocery store cards. You get a discount and they get to track your purchases. It's more of a problem with ISPs because they act as a utility but are trying to run as a business. Imagine if your power company sold your usage to another company. The big problem is ISPs not being treated as what they are, utilities. If they aren't utilities, they're a monopoly. They want to have it both ways.
I know China suffers from overpopulation. So what is better about new two-child policy than old one-child policy?
China is more concerned about an aging population, where there are too many elderly and too little people in the working force to support them. Also, the one child policy has largely been a failure, and has been revised a couple times to allow for more children . For example, if both parents are a single child, they could have 2 kids. And if you live in a rural area you could have even more. Lastly, thanks to this policy and Chinese cultures, most parents want a boy to pass the family name. Therefore, if they get a girl, very often parents end up putting her in an orphanage or aborting her before she is born. This resulted in an imbalance of boys and girls. P.S. This is straight out of my memory and I'm on mobile now. But I hope this answers the question.
How is it large herbivores such as cattle, moose and deer can grow so large on a diet of only grass?
Hervibores have a specialized digestive system that helps them acquire much more nutrients from those food sources that would just pass through our own digestive tract untouched. Also, all they do while they're awake is either eat or look for stuff to eat.Humans aren't able to break-down cellulose, the "walls" of plant cells so to speak, but the herbivores you referenced can and there's actually a lot of protein grasses. In fact, most megafauna are herbivores because a number of plants are incredibly protein-rich, and a significant decline in a specific protein-rich plant called a "forb" after the last ice age played a [major role] in the extinction of various megafauna . And while we're on the topic, it should be noted that many smaller species rely on megafauna in one way or another for survival, so their extinction is sometimes linked to the collapse of entire ecosystems, which of course means protein-rich plants can be linked to the health of entire ecosystems.
What raw materials/ingredients are used to make antidepressants.
The process of synthesizing a medication starts with some commercially available reagent which is acted on in various ways to create the desired molecule. What that initial reagent depends entirely on the drug in question. For example, citalopram, a widely used antidepressant, can be synthesized out of 5-bromopthalide, [which can be purchased from suppliers]. That reagent is combined with others under specific conditions. Chemical reactions occur. At the end of the process, you end up with citalopram. It's basically like cooking. You go to the grocery store and buy flour, eggs and sugar, then you come home and combine them in the right way to bake a cake.
Why DON'T we kill off mosquitos?
Here's an idea. When we remove an organism from an ecosystem, we don't know what will show up to fill that niche. What if it's something worse than mosquitoes?
What is Bio Chemistry, and what do Bio Chemists do?
Biochemistry is, simply put, the study of the chemical reactions that underlie biological systems. Think of the way proteins are formed, or how glucose is broken down into ATP. Besides academic study and aid of related fields like pharmacology, biochemistry has a lot of industrial applications nowadays, such as the development of compostable plastics or biological remediation of pollutionAt the tiniest level everything is made up of atoms. Imagine them as simple Lego building blocks. Some things are really easy to make, like building a wall out of Lego bricks, but living things are VERY complex. A living cell is like a crazy complex Lego machine that has all sorts of moving gears and machinery that can put itself together. Bio-Chemistry is the study of those crazy complex machines, what pieces they are made up of and how those pieces can connect to each other, again like a Lego brick. Bio-Chemists do that actual studying. They try and figure out what the pieces are and find new ways they could connect. They try to build different machines by swapping some of the pieces out and seeing what happens. Then they try and see how useful their new machines are for doing things in the real world. /u/TokyoJokeyo explains some of the uses for this in the real world.
How do they recover deleted data from a HDD?
Usually when you delete a file on a HDD the data isn't actually deleted. Instead, the drive is just told that the area where the data is stored isn't important anymore and it can be written over. If you keep using the HDD, it will eventually overwrite the old data, but the data will remain on the drive until then. Your operating system tells you that the space on the disk is free because it's available to use for storage whenever you need it, but the computer isn't going to go changing the data until you have something else to store there. You can use a file shredder to clear the data out, but most people don't do that. Additionally, HDDs use a magnetic field to store information. A strong field indicates a 1 and a weak field indicates a 0. However, magnetic fields aren't binary and with a lot of work you can sometimes figure out what deleted data was based on the strength of the magnetic fields that remain. Edit: You can't actually recover any meaningful data this way. On older, less dense magnetic storage media it may have been a possibility, but that's not the case with any relatively modern HDD. The idea comes from a guy named Gutmann who wrote a paper on it in 1996. It would have been hard to do then and Gutmann himself has said it would be next to impossible these days. It works differently with internal SSDs. Those usually clear the data out after it's deleted because and SSD can only store data in an empty spot. Consequently, your computer goes ahead and clears out the data after it's deleted to speed up the process of writing new data to that area in the future.

How exactly could the Mexican Supreme Court ruling over marijuana help fight the cartels?
Cartels make their money, and thereby get power, by selling illegal drugs. If the drugs become legal, then anyone can sell them, draining money from the cartels. Further, the legal sales can be taxed, bringing money back to the government, improving their situation. Further, if things like the growing and selling of weed are legal, it means that the people doing that don't *need* to be criminals. They can go legit, and that means they don't need to be involved with the more violent criminal elements of drug dealing. That's the idea at least. Could always backfire of course. It's been done a few times in other countries without the world ending, but only time will tell how it works out in Mexico.
why is the search for life on other planets based on the things life on earth needs to exist?
It has been considered, but Earth is the only planet we know of with life, so when we search for life on other planets, our best guess is to look for planets like Earth. Imagine if you moved to a new town, and you wanted to buy your favorite snack. Now, your old Town had a Food Lion, and it had your favorite snack. The new town has a Publix and a small Dollar General. Now the Dollar General might have your snack, but you're probably gonna go to Publix first because it's also a grocery store and it's a lot more likely they'll have what snack you're looking for. Same basic logic applies to searching for life on other planets.

why do phones need to be charged more frequent over time?
Batteries wear out after being charged again and again and again over years. If you noticed that devices using disposable batteries don't have this problem it's because it's getting a fresh battery with all its charge each time. All rechargeable devices, including laptops and handheld gaming devices, will have their batteries wear out, but the former has a very large battery and the latter isn't used with the same frequency as a smartphone so users don't notice it to the same extent. Replacing your device's battery, if you can replace it, should see a sharp increase in battery life.On one end of the battery you have an anode and on the other a cathode . In a healthy battery ions flow freely between the cathode and the anode. The process of charging a battery forces ions out of the cathode and back into the anode. This process wears out the cathode resulting in a decreased capacity.
What made marijuana illegal in the first place?
Paper, cotton, and tobacco owners lobbied to the government to make it illegal. They did this because marijuana/hemp single handedly is better than all of the other three combined. And the owners of those businesses wanted to remain rich and powerfulPost-prohibition cops keeping their jobs. It got really bad though when Regan made having more people in jail a better return on a hedge fund.
Why, after I masturbate or have sex, do I get an extremely uncomfortable feeling in my groin that seems to last about 10-20 minutes?
Yep. Know what you mean. Only seemed to happen the most after drinking. No idea what was or why it did it. 1 out of every 4 to 8 times it would happen and I had the same tube switching thought as well. Felt kinda like passing a tiny warm stone starting at the base? Sucked.This sound a lot like prostatitis but I can't tell just from the history. It's an inflammation of the prostate and it's not that uncommon. Go see a doctor and tell him about it. He'll probably do some examinations and prescribe you some doxycyclin or some other antibiotic. That is if I'm right.

You can probably just take some antibiotics.Your prostate surrounds your urethera and during sexual arousal and ejaculation the pelvic floor muscles and the smooth muscle of the prostate contract pinching off portion of the urethera that connects to the bladder. The prostate also produces fluids present in the ejaculate so there's some additional enlargement there. After sexual activity, particularly during longer encounters the muscle will take some time to relax so your urethera might remain constricted. When you try to pee, particularly if you had a full bladder you'll notice increased pressure and discomfort. As others have noted this might be exacerbated by prostatitis, so if it's bothering you it won't hurt to see a doctor.
Why is it that when I'm suddenly tired my eyes begin to cross?
For the same reason you're more likely to begin feeling cold, too. You're body is basically trying to force you to find a warm, comfortable spot and close your eyes so it can fall asleep.
How were the point amounts determined for the NFL?
As far as to why extra points exist: Football and Rugby evolved from an earlier game in which what is now the "extra point" was the only actual point-scoring play. The team was required to touch the ball to the ground inside the end zone in order to try for the point . Those games tended to be very low-scoring, obviously, so over the years as football and rugby have evolved, rules emerged to allow the actual touchdown and try to score all on their own, so that now, the TD or try scores you more points than the actual, original, point doesTrial and error. When football was first evolving, they basically tinkered with the number of points awarded until they got a balance they like. This is an ongoing process the NFL last changed its scoring in 1994, when it added the two point conversion, and is considering changing how extra point kicks are scored in the future.
Why does the jolly fat man dressed who delivers presents at Christmas get referred to as 'Santa Claus' by some, and 'Saint Nick' and 'Father Christmas' etc. by others?
The Santa Claus character is based on Saint Nicholas, who was a real person. He was known for delivering gifts to less fortunate children. The name Santa Claus is derived from translations of Saint Nicholas' name in different languages. Sinterklaas and Sankt Nikolaus show some similarity.
Modern methods of attacking cryptographic systems
The idea is that if we can't break the encryption, we can try to break the system instead. **Man in the Middle attack**: Lets say Alice and Bob wish to communicate securely. Alice contacts Bob. They set up an encryption key using a key exchange protocol such as the [Diffie-Hellman], and from that point on they encrypt their entire communication. Sounds secure, right? Well, not if Eve, a malicious eavesdropper has something to do with it. Eve somehow manages to intercept the communication - everything that goes between Alice and Bob goes through her. When Alice tries to set up an encryption key with Bob, Eve pretends to be Bob so that Alice actually sets up the key with Eve. Eve also pretends to be Alice to Bob, setting up an encryption key with him as well. Now, whenever Alice sends Bob a message, she encrypts it using the key she had set up with Eve. Eve can decrypt the message and re-encrypt it using the key she had set up with Bob. Moreover, Eve can even *change* the message as she pleases. **Side channel attack**: While encryption algorithms might be mathematically sound, they still have to be implemented in a physical device or computer program. A side channel attack attempts to extract information from the specific implementation, by monitoring things like the time it takes to encrypt a message, the memory and power consumption of the algorithm, and so on. For example, the RSA algorithms use a series of additions and multiplications to decrypt a message. The order and number of these operations is determined by the decryption key. If, for example, the multiplication causes the computer to consume a little more power than addition, then by monitoring the power consumption we can determine when the computer performed a multiplication and when it performed an addition, and from there reconstruct the key .
Why do some countries call 911 while others call 999, 000, etc?
Back when rotary phones were a thing, higher numbers took longer to dial. 999 was chosen as an emergency numbwr, but could easily be misdialed during stressful situations. When it was adopted here 911 was decided as easier number to dial. All largely irrelevant now that those phones barely exist outside of museums.
if being frozen causes cell walls to burst, why does my grass not die when my lawn gets a frost?
Just because there is frost on the grass doesn't necessarily mean that the cells themselves have suffered temperatures low enough to freeze. But, low temperatures can indeed cause the death of grass. Some grasses, however produce their own "anti-freeze" in the form of proteins that inhibit the growth of ice crystals.
Why do american high schools teach advanced calculus and complex numbers, but still manage to be behind countries like germany in PISA or similar tests?
Because the majority of students never take those classes. Simple as that Theyre options, but fewer and fewer students are getting there. A big part of it isnt even ability, we're pretty laid back in terms of academics and its made a lot of students kinda lazy. Its not hard to tell the difference, I've seen folks have to study 4 hours a night in Algebra one just to understand it enough for a B. Others, I've never seen study or do anything math related outside of class and blame the teacher or their own intelligence when they fail a test. I know this experience isnt exclusive to me Our standardized tests in particular are meant to measure your knowledge and make sure its at a level that allows you to function in society. If you can do that, who cares? I mean, I'm not gonna judge someone for not being an engineer or chemist as long as they arent a detriment. Europe tends to put more focus on scholarly achievements, whereas in the states its not that big of a deal. College is fine, by why go when I know I hate academia, can get high quality technical training for something like welding, get a union job and make 40K+ at 18? If prealgebra is whats needed to function, we're not gonna put Pre-Calculus on all our standardized tests
When did drinking warm milk to help sleep become popular, and why if it doesn't work?
Ask any newborn if drinking warm milk help them to sleep :) They won't answer because they can't talk *but if they could* they'd probably say that it does. The oldest mention of this practice that I am aware of is in the old testament in the story of [Jael]. I'm sure there are probably even older references than that but the point is it's nothing new.
What are the actual sizes of pen point sizes in NA?
The easy answer is that there is no uniform "standard" for pen point sizes, although many of the big manufacturers pretty much agree on a few points . And even then, there is notable variation between brands and types of pens. Put simply, the culture of the US doesn't care much about the writing implements used, where some other cultures do.
How are "celebrity nudes" leaked?
Remote storage in the "cloud" is inherently susceptible to exploitation. Also, the media in question may not be in possession of the celebrity . Additionally, leaked nudes or porn are a great way to drum up press. Think about it, if Kim Kardashian or Paris Hilton hadn't gotten plowed on camera would we care about them?', "Probably not. Touching a celeb's cell phone is not an easy thing to do. However, most people synch their phones with some cloud service. If you log into their cloud account, you can download the photos synched there. It's a lot easier, and safer, than trying to grab their stuff.
why does our Brain get attached to people, things, places etc, and why do we have a strong need to find the one we love
Probably all to do with our survival instincts. We can get attached to places as a way to demonstrate that it's "our area", and to produce offspring we adore the person that is deemed by our brain as the best mate, for healthier and stronger children. This is my biased idea, so take it for what it isLike other great apes humans look for love and gain attachment to build community. This provides safety and security. A sense of belonging also helps give people an overall better mental state.
If lottery money goes to 'education' then why are school so bad?
Not all lottery money goes to education, lotteries by themselves don't cover all the costs of schools, and the major problems with school systems have little to do with funding.
