Why isn't water a super conductor?
Electrical conduction is heavily influenced by the movement of free electrons, or electrons that are not used on bonding between atoms and are able to conduct . Metallic materials such as copper and aluminum have a high amount of these free electrons. Another effect on conduction is the 3D arrangement of atoms in a solid materials. Certain arrangements allow for easier electron movement between atoms than others. Energy is lost when these conducting electrons hit other atoms, dissipating energy. the dissipated heat is the observable heat generation in a wire due to resistance. Superconducting occurs when electrons are actually attracted to each other allowing them to form pairs. Normally electrons repel other electrons, but paired electrons act differently, which allows for zero energy dissipations during conduction. Conduction in this case is of the electron pairs and not just individual electrons. So why not water? Water forms a disorganized 3D orientation of molecules in solid state. . In a single water molecule, there are two hydrogens and and oxygen. Of those two atoms, only oxygen has electrons that can conduct, but oxygen wants to hold onto these electrons and if the electrons where to conduct, there is not easy movement from one atom to another even as the special paired electrons. Non-metallic materials that work as super conductors are highly ordered and contain metal ions such as the compound yttrium barium copper oxide which contains copper. In this ceramic material, conduction occurs with the copper. The wiki page on superconductivity is worth looking at. Hope this helps.
Why do Americans hate cursive?
Because it's impractical a skill. Everyone's handwriting is different, and some people, like me, have near-illegible handwriting no matter what. Not to mention it's forced on people, and anyone in adult life who demands something in cursive will be laughed at and told to go fuck himself. Many forms mandate that you should write in print so you don't wind up with errors on important documents when the data is taken up by someone else.I honestly feel when it comes to speed and taking notes in school people use what is legible and comfortable. I have a weird font and a college prof said it reminded him of Lord of the Rings. No one wants to stop in the middle of a lecture and remember how to write z in cursive or whatever. I think people write how they are comfortable.I love cursive, write everything in cursive and have no problems with it. Actually, I've never seen anyone else have a problem with it either. I never had a prof require print unless your cursive wasn't legible. I am an American, and saddened by the fact that school don't teach it anymore.
Where I live, I pay a water company per litre of water I use. If that's the case, what's so bad about what Nestle is doing with water privatisation?
You don't pay water company. You pay the water utility, which is a branch of the municipal service of the city/county. It's not a private company that's trying to make a profit off you.
Why is CPR for drowning different than CPR for people who collapse from heart problems? e.g rescue breaths are recommended for one but not the other.
Question has already been answered pretty well, but I can provide a relevant aside. The training I receive as a police officer in the UK differentiates not only between collapsed/drowned adults, but also between adults and kids. For *all* kids we begin with breaths. The rationale is just one of likely causes. If you look at the overall numbers, kids who collapse are more likely to be doing so because they are having difficulty breathing rather than because they have difficulty circulating their blood. ELI5: kids are more likely to swallow things and choke and don't normally have heart attacks, whereas adults are more likely to have heart attacks but don't tend to put things in their mouths and choke. For the typical kid, beginning compressions without breaths will just circulate blood that already has too little oxygen in it, so the first step is to get oxygen into the lungs. For the typical adult, there is already oxygen in the blood but it's not being circulated so the first step is to get that blood circulating before replenishing the oxygen.
Why is ISIS battling for territory and land? Wouldn't it be more effective to keep building army and not trying to take over key areas, ultimately exposing yourself?
Also, they aren't an army. They aren't thinking strategically like a real army would. They've set a goal of making an Islamic nation by force, with no real thought as to how they will actually do it whilst being attacked by real military powers.
Why is that when you blow a balloon too hard, little air pockets appear inside your mouth just below your ears?
Audiologist here :) I'm going back a few years to my training so bare with me.What you are doing is forcing air through the tube that connects your throat and middle ear. There is only limited space in the middle ear so forcing air in can cause the ear drum to bulge outwards pulling the surrounding area potentially causing the pain. Think stretching skin too much, it can only go so far without pain or something ripping. When this happens in your ear your eardrum bursts. This pain can also occur whilst flying as the pressure changes outside and you get a pressure sensation in your head/ears. To relive this you swallow causing air to go up into the middle ear. If you don't do this whilst flying your ears can become very painful or burst. 'and when you squeeze them, tiny air bubbles comes out of it' I'm guessing from this you are trying to relieve the pressure by moving your ears. Could be a couple of things. 1: by pressing on your ear potentially blocking the ear canal and pushing you are forcing aid down onto the eardrum and pushing it into the middle ear. When doing this it may force the eustachian tube open . 2: if the pressure in your ear has been there for a period of time your middle ear reacts to it. The cells in the middle ear expell liquid into the middle ear . This causes a congestion behind your ear drum. Which has many names but alot of people know it by glue ear. Glue ear is common in kidsHope this helps :)
What happens if I don't sign up for Obamacare before the deadline two weeks from now?
Just signed up my folks for this yesterday. late 50's with a small business of 4 employees. they were paying 700 bucks a month for shitty insurance that barely covered anything. Now starting april 1st, they pay 260 bucks for both of them. Over $5K in annual savings. Thanks OBAMA.I live in Oklahoma, have insurance through my employer, where I make approximately $55K a year. My problem is, I take care of both my parents who are 60, have no jobs, insurance, disability, or social security. They receive $175 a month in food stamps . When I "signed up" for Obamacare, the cheapest plan was $165 a month, per person. That is including the Federal stipend for low enough income. $330 a month is too expensive for us, as we are already barely getting by on my income. I'm not sure what else to do, or if I'm missing something vital. Any suggestions Reddit?There are a lot of people here asking: "Help! What do *I* do?" The best place to ask that question is at the office of a local "navigator." These are people who are trained to walk you through the process. This help is free. Many churches, hospitals, and community centers have navigators. Just go and sit down with somebody who really knows what they're doing, it'll make the whole thing a lot easier: _URL_3_', "As long as everybody else is asking for their specific case, I'm going to jump in too. So I'm unemployed, uninsured, and living with my parents. Last year they were able to claim me as a dependent relative for a $1000 credit. If they do that this year, do they then have to pay 1% of their income due to my uninsuredness?
is it better to have a shower in the morning or at night?

Why is there only so few female inventors?
Also, female inventors aren't given the same social standing as male ones. [Jeri Ellsworth] is a brilliant electrical engineer, but who knows about her? Nearly nobody.Maybe it comes from the past when men worked and woman looked after their children, the house etc?
Why can US celebrities openly admit drug abuse and suffer virtually no consequences?
Ok Wiz Khalifa blatantly [possesses weed in music videos]. You can also see him smoking at 3:12 in that same video. I've always wondered how he of all people doesn't get into trouble. Can someone please explain this to me?", 'Because admitting to using drugs is not the same as having them. I could admit to murder and probably get arrested, but unless they link me to a murder then they have nothing to charge me withWhat about some people like snoopdog, cat williams or wiz khalifa how smoke weed on live TV? how can they get away with it when there is video evidence of the possessing and using illegal substances?', "Bill Maher talks about how he smokes pot just about every episode of Real Time. It's risky in a way, but it just depends on how much LAPD wants to get a warrant to bust him for it. Remember, a lot of cops--perhaps most cops, especially in urban areas--are fucking over the War on Drugs. They're given the shit end of the stick and, many of them, are *tired* of busting people for weed, because at the very least that's paperwork they don't want to do, and more importantly because the cops don't see the harm in smoking up. Because surprise surprise! A lot of cops unwind at the end of the day with a joint themselves. The really draconian cops and judges are the rednecks in rural areas, mostly.
Why is Florida the site of most, if not all shuttle launches in the U.S? Why not something with more consistent weather like Arizona?

Why is it that we talk about establishing a civilisation on Mars but not the Moon? Like we've already been to the Moon. Why is this not discussed?
Mars has more resources than the moon. It has water rich soil and a nitrogen rich atmosphere. Mars is colder on average than the Earth, but there is sunlight for solar panels and Equatorial temperatures can reach 20°c in the Summer. The atmosphere is thin but offers protection from radiation, unlike the moon which has none. At 24 hours 39 mins and 35 secs, a day is similar in length to that of Earth, while a day on the moon takes a month. Gravity on Mars is 38% that of Earth; the Moon 16%. The feasibility of a base on the Moon, colonising Mars, or both , is often debated in regards to the technical hurdles and substantial costs involved. ~~As they can never make up their minds on the goals, we likely won't be doing either anytime soon.~~ [Current plans] involve a 'space launching system' in orbit around the Moon, but no plans to land on the surface.

Why can't our teeth heal like our skin and bones?
You can, and it's called remineralizing. However, it doesn't fix major cavities/broken teeth.Dental Assistant here. My boss figured out how to remineralize enamel. If a cavity has not yet reached the Dentin, we can fix it without a filling. We use ozone gas which is pure oxygen to sterilize the tooth. Because it is a gas it can travel through the dentinal tubules. Once it’s sterile, our patients rinse with calcium phosphate, which is the remineralizing part of the whole process. It’s not FDA approved so all our patients have to sign a form if they want to use it. My boss was a chemist before he became a dentist, and he always says “The best kind of dentistry is no dentistry” and has great tips on how to not get cavities.They can. Do some research online about it. They just can't recover from the torture we put them through. The sugar especially keeps them from healing. Its like if u had a rash from deodorant and u kept using that same deodorant every da. The rash would never heal. Now that I've wasted ur most valuable time nothikng of what I said is backed by valid research but doesn't it make sense.
what actually causes genetic issues if breeding pair are for example siblings?
From the sociological standpoint, part of the reason the taboo cropped up in the first place is because incest can be a recurring problem. Genetic deformities and conditions are more likely to crop up over time if siblings keep procreating with siblings, and that's more likely to happen in small breeding pools - such very small and geographically isolated communities. The taboo against incest is a social mechanism to defend against the 'physical' circumstances that so easily and frequently predispose a community towards incest. The 'easily and frequently' part is also important when it comes to taboo. There are other things which can increase the likelihood of a child being born with birth defects, such as having a child when you are significantly older. But, historically, this was something that rarely happened, and even when it did, it rarely happened multiple times in a row. Things that led to a pair of siblings having kids with each other have historically also predisposed *their* children to fuck each other and have incestuous children together. But it was unlikely for the children of a significantly older couple to also hold off procreation until they're older, and for *their* children to do so again. Others have explained the genetic process by which incest increases the likelihood of birth defect and how recurring incest can compound that defect over time. A taboo is a social mechanism to prevent these defects from happening in the first place.
If captchas look at your mouse movements to tell if you're a bot, how does it work on mobile devices?
All the top comments in here are correct. As well as JavaScript being able to access gyroscope data from your phone. Especially useful if you're holding your phone in your hands as the gyro data will change all the time which the captcha tool could also use. We'll never know the exact algorithm they use, cause if we did, then it wouldn't work! Hope this helps!
Why can't I remember any memories before the age of 6 or 7?

What happens to a persons assets if they are arrested?

Why is voting for a third party candidate in the United States "Wasting your vote"?
The 2000 US Presidential election is a good example of this. The election was very close, George W Bush defeated Al Gore 271-266 electoral college votes. The state of Florida with its 25 electoral college votes was won by Bush by a few hundred votes. Had Gore won the state he would've won the election. Ralph Nader, the Green party candidate, attracted 418,707 votes in Florida . Given the positions of the Green party tend to be closer to the Democrats than the Republicans, it might be assumed that most of the Green party voters would have preferred Gore over Bush. But by voting for Nader rather than Gore they allowed Bush to win. This is an absurdity created by all plurality election systems . In Australia candidates are numbered from favourite to least favourite and are eliminated one by one in what is called an instant-runoff. Such systems do not suffer from this problem. _URL_2_ _URL_2_
How do they find a bacteria in a restroom? Are Airport Bathrooms Spreading Antibiotic-Resistant Bacteria Globally?A rare strain of MRSA originally from India has been detected in a Paris airport bathroom.
Because public restrooms have thousands of bare hands touching them every day. All you have to do is swab the door handle with a piece of cotton, put it in a petri dish, and see what grows. They know to look in a restroom because it's a very public place with many many bare hands touching it, which means they can get a good idea of the various bacteria on the population's hands, as opposed to something like a cell phone which is just as dirty but only tells you about the one or two people that use it.

Why is Venezuela so destroyed at the moment?
From what I understand the majority of their economy relied on oil, Venezuelas pretty much only decent resource. When the arse fell out of the oil market some time ago countries that relied on it also crashed. The market recovered somewhat, Venezuelas economy did not. I think there are also the usual problems with corruption, but that is just a guess based on a history of not-entirely-honest governments in the region over a long period. Tldr - oil market fucked 'em
Did we always instinctually know that sex led to reproduction, or was there a point where someone put it together?

EL15: Why is it so hard for a woman to have a natural delivery after a C-section?
It depends on individual cases and it will also depend on what the reason was for your first C-section. For example, if you had an infection and that was the reason for your first C section, and you don't get an infection this time, there might be no need. The main reason would be that your uterus has already been cut open and this gives a higher chance of the uterus tearing/rupturing along the scar this time. If the first C-section was done with a 'low-transverse incision' - a cut low and horizontal - the chance is lower, but if the incision is vertical or T shaped it can increase the chance of the uterus rupturing with a vaginal birth. The low-transverse incision makes stronger scars and bleeds less. There might also be other problems that would prevent you from giving birth vaginally - certain health conditions like diabetes, problems with the placenta, etc. It's best to discuss your options with your doctor/obstetrician. Some women do have successful vaginal births after C sections but it's not suitable for all. :)
Why do poachers hunt animals to extinction?
I'd say it is a perfect example of the [tragedy of the commons[. In situations where resources are shared, it is easy for individuals who are looking out soley for their own profit to collectively harm the public resource. The same thing happens in many other ways, such as air pollution. No one thinks that their small contribution to the decline of something big matters much. But it does, when enough fools think like that.
What is the point of spending years of your life developing software when people will just download it off of a torrent site for free after it's released?
You're banking on enough people wanting and being able to do the right thing and pay for the software. And judging by the many companies/people that manage to pay the bills by developing software, it's not necessarily a bad bet.
What is an executive order in US politics?
The US government is divided into three branches. * Executive - the president's office.* Legislative - Congress* Judicial - the courts In the case of the executive branch, the president can push through executive orders as laws and they kinda . just happen. It's the rule now. However, he cannot change the constitution with an executive order, cannot make executive orders that go against the constitution, and can be impeached and lose his job if congress thinks he's abusing the privilege.
Do average people really produce $115,000 of stuff per year, yet take home only $26,000?
one thing youre forgetting, all companies have the basic requirement to make money and grow, this means that a good portion of it must be re-invested into the company. As I am starting a small firm with some friends we've been studying company structures and for small companies it can be as much as 75% of total monies for larger it can shrink but still usually top 25%.I think this topic is trying to touch on the whole 99% thing.
how wireless charging works and why it can/can't be put in roads to power electric cars?
I wish a mouse manufacturer would build charging into a mouse pad so we could have wireless mice that don't have to be plugged in to charge or require a battery swap.Way too many bad assumptions being made in this thread. Wireless charging CAN be used to power electric cars. I saw the demo for [this news piece] . **Tl;dr** we currently can get 90% efficiency with a 10" air gap for 5kw transfer. Now it's more practical just to add charging stations in parking lots and replace the meters with credit card readers, but you can build a road that has the car recharge on it. It hasn't really been done but estimates are around double the cost of a normal road. I do know some of how they do it, but am unable to share it. I'll allude that it's mostly standard engineering elbow greaseI thought that there was an article some time ago about using the roads as an electricity grid - if that could be possible, then I am sure you could have wireless charging of cars on the go somehowThis is called electric induction. This is commonly used in heating pots and pans on your stove, and also in water boilers. See _URL_2_
Why do we get a feeling in our chest/stomach when we have sad/bad thoughts?

Why indigenous women in Canada have been murdered or gone missing at such a high rate?
Extremely high rates of drug and alcohol addiction have ravaged many, if not most native communities in the country. I saw this first hand working in a rehab centre. The government pays for their rehab, pays for their education, and basically guarantees them a job upon graduation. But 99% of the time, it doesn't mean a damn thing if they keep going back to the same people, places and things over and over again. People in government and the media who have never worked and lived in these communities dance around the real issues facing these people. Seriously, decrying the plight of natives in Canada as being a result of racism, lack of education, poverty, sexism, etc. is kind of missing the point. The fact is, none of the aforementioned issues go away until a person gets sober. This reality is not exclusive to aboriginal people, but is exasperated when many of their longest suffering populations are segregated either by personal choice, or short sighted government policy introduced in the 20th century. I've lived or worked on or near native communities in Nova Scotia, Saskatchewan, Alberta and NWT and have met more people diagnosed or suspected to have FAS than people who can safely drink alcohol or recreationally use drugs. A young native girl who may or may not have an undiagnosed mental health problem, probably a drug addiction, with little to no reliable support system doesn't really have a chance. Same for the young men, but I am not sure if people even care enough to keep any statistics of them.
why do we have a constant "R" in the ideal gas law?
The formula is about a relationship between to different basic units of measurement. We need the constant to convert from one unit to another. PV = nRT P = pressure in atmospheresV = volume in litersn = number of molesT = temperature Consider the units. PV is in = /nT is in So either we need a gas constantR = .08206 / Or me need to decide that deg Kelvin isn't a basic measurement and define it as /. It turns out most people don't like that.
Why can't we move our eyes in one smooth motion unless we're focusing on something? (fx. car that's moving)
This happens because when your eyes are moving, you can't actually see anything. It's all blurry. But we have evolved so that we can move our eyeballs in our head to keep them still enough to get a good picture while we move our head around. You can see the disadvantages of not being able to do this in other animals like chickens. The reason why some animals seem to 'bob' their head around when they look around is because they can't move their eye balls in their head, so they have to move their head from still position to still position in order to be able to see. **TL;DR When we move our head, our eyes are jumping from still position to still position so everything isn't blurry.**

Why do 2 windows allow better airflow?
It's pressure! Blow into an empty bottle, you can only fill it so much under sea lvl pressure, then the air will stop entering the bottle. Now cut a hole into the sides or back end, see how it flows. You reduced pressure.Because air can freely go through the room instead of going back out the same way. That leads to better airflow
Why don't more people just buy generic drugs if they are the same as the expensive ones?
they usually do. but a lot of drugs aren't generic. the manufacturer gets a 12 year period for patent before any generics are allowed to be made. so during this period, they jack up the price and make the monies before generics drop the price way down.
If everyone in the US is required to have healthcare, why do we still use open enrollment periods?
The real reason for Open Enrollment is to prevent you from switching to better insurance right before claiming you're sick. If you pay a super low rate all year and have a crazy high deductible and then get chest pains, you could switch to the better insurance and then go see your doctor.
Is it beneficial in any ways to mature early/late compared to others?
Plot twist: OP is actually five and is genuinely concerned. Jokes aside, I remember one finding that indicated that, at least socially, early maturation tended to be beneficial for boys and problematic for girls. The way tweens and young teens treat or refer to developed bodies is heavily moderated my gender. Honestly, there's maturation and then there's everything else. Development timelines vary significantly from person to person, and if there are any benefits or detriments, they are largely a social production.
Why have shields never been used in warfare since the popularization of guns?
On top of all the reasons listed below, there's a big one: most people on a war battlefield aren't going to be killed by small arms fire. They're much more likely to be killed by an artillery shell. While a ballistic shield may protect you from fragments to the front, it'll do bugger all against the blast or a shell landing to your side or behind you. As has been listed below, building a shield like the one your propose--and having the soldier carrying it remain combat effective--is much harder than you think, and would also not be as effective.

How can grocery stores get away with selling virtually the same product as a major company just by switching up the name up and calling it store brand?
Most food items are just arrangements of ingredients that cant be copyrighted/trademarked. Take Kraft mac and cheese for example. Its elbow macaroni and a cheese sauce. You can't copyright that. The EXACT formula is probably a secret, but everyone knows what's in them generally. Food scientists can easilly reconstruct the basic cheese sauce.

New Horizon is travelling at 31k mph. How is it possible to capture a photo in such low light conditions while moving at this speed?
I saw somewhere in [the NASA IAMA] that they take many shorter exposure photographs and combine them, because it doesn't require the probe to be as stable. I can't find the exact link, it's likely in one of the 'load more comments' bits. It's moving at 14,000 metres/second. A decent consumer digital camera can take a 1/8000th of a second exposure. That would mean the probe moves 1.75 metres in one picture. NASA can likely afford faster, and more light-sensitive sensors than a consumer grade digital camera. The probe can turn, as well.I read that as 31 kmph and was confused how the probe could travel so slow. The earth is rotating around the sun at 30km/sec, yet we're able to pick up some pretty badass pictures of the sun/other planets, other stars, etc. Also considering the technological advances that NASA produces, the camera is also pretty badass.
Why do actors (especially popular ones) get any say in the script or general film making process?
Because making a movie is a collaborative process. Unless a director is a control freak, it's generally expected that they'll take input from the actors. Also, very often things read better on the page than they come across when you're actually acting them out. That's why writers are given the advice to read their dialogue out loud to see if comes across as natural. Sometimes an actor can make weird or stilted dialogue work and sometimes they can't.
Why do fast food and casual dining places need to nickle and dime us on some things but not others?
My wife works in supply chain at a larger fast food chain in the US. I was told that the landed cost of a dipping sauce is about 20-23 cents. They charge 25 cents to the customer for an extra, so they aren't making much. Knowing this has opened my mind about paying for extras.
Why do people from China keep trying to sign into my Google account?
If you have a smartphone I would highly recommend setting up 2 factor authentication. It makes it so that two passwords are required to login. One being your usual password, the other is a 6 digit number that changes every 30 or so seconds. You setup Google's 2 factor authentication app on your phone in order to generate/display this second password. _URL_2_
Why do people keep saying the bombing suspects "are from Chechnya, not Russia?" Isn't Chechnya in Russia? Wouldn't this be like saying "they're Texans not Americans?"
It would be like saying they were Faroese, not Danish; Basque, not Spanish; Quebecois, not Canadian; Tibetan, not Chinese; etc. They're formally part of a country despite not wanting to be.It's pretty much *exactly* like saying "they're Texans, not Americans" somewhere around 1850Pretty much the same reason why we say Tibetans and not Chinese.
Why does my phone reception strength vary so much when the phone is completely stationary?
Pretend you're taking a bath. Each Barbie doll you play with in the water is like a cell phone on the network, the water level is the noise floor, and your glistening, wet five year old body is the signal. As more Barbie dolls are added to the tub, the water level increases and less of your body can be seen. This is one fairly large factor to why your cell phone signal can fluctuate, stationary or not.
How can we estimate that the golden record on Voyager will last a billion years?
Space is not empty; there is dust everywhere. On average, there are about 0.1 to 10 particles per cubic centimeter. It's mostly hydrogen which isn't a big deal. Over time though, the effects of this constant barrage of dust will degrade the record to the point where it becomes unplayable.

Why is advancements in gun technology quickly protected by the 2nd Amendment but what's considered persoanlly online property isn't protected by the 4th Amendment?
The 2nd amendment protects your tight to own something, it's not difficult to determine what is ownership or if a particular item is one of the type that you are protected to own. The 4th amendment protects you from unreasonable search and seizure. What is reasonable, however, has been under a LOT of debate; however, current law boils down to this: if a search is done with a warrant obtained from a judge having been presented sufficient evidence that one is needed, then it was reasonable, or if a search was done in a way that does not involve officers intruding on your privacy then it was reasonable. Remember, to, that the amendments do not say what YOU can do, it says what the government cannot do to you; the government can't prevent you from owning guns and it can't search when and where it's not reasonable Now, we come to online property, and judges, who are not necessarily technically inclined, have to decide if the online property counts as being in a public place. given free reign, they're going to err on the side of getting their jobs done. Generally speaking, personal online property can be freely viewable to the public, and almost certainly controlled by one or more companies that can be served a warrant which allows for that data to be searched and potentially seized.
How is paid suspension even a punishment for police officers?
Paid suspension is not really intended as punishment but to avoid prejudicing an investigation or creating a possible conflict of interest, although it has not been proven that the officer in question is either guilty or innocent. If they are guilty but kept keep their full job during the investigation period they can interfere with the investigation in their favour. Even if they don't do this it may be seen as a conflict of interest or at the very least questionable judgement. So thus it's typically a good idea to keep an accused officer away from work. If they are kept from work then they will have no source of income during the investigation period. If they are innocent then it is unfair to them for being punished for a crime they did not commit, thus the paid portion. If fault on the officer is ambigious or possibly not there then the suspension will likely be paid. If the actions of the officer were clearly unjustifiable then they will go unpaid as punishment. Of course there are internal political motivations as well but we will assume we are in an ideal world. It really is up the police department to decide if an officer goes paid or unpaid but generally:Suspension = we can't have you working as a police officer while the investigation is carried out.Paid = we think that you may be clear of wrongdoing and don't want to inconvenience/hurt you or your family financially while you are off work for an indeterminate amount of time.Unpaid = we think that you clearly did wrong and as punishment we want to fire you but need to do an investigation and trial first.
why is it that in my dreams I can never hit someone/something hard? It always seems like I'm physically restrained.
I got bit by a dog in one of my dreams, it didn't hurt, though it did scare the shit out of me", 'I have the same thing. Or more often that I am being chased and cannot run. Yet I am also constantly dieing in my dreams as well
Would the human body grow any differently if it was conceived and born in zero gravity and what would these differences be?
Quite probably, although we haven't performed this experiment. But it's worth noting that the human body undergoes fairly rapid changes in orbit (which admittedly is not really a 'zero gravity environment.' At the minimum, our skeletal and muscular growth is profoundly affected, due to the lack of stresses we experience interacting with gravity on earth. This would probably result in some critical developmental weaknesses.
When watching TV with subtitles, explain why our minds always (seemingly) choose to read text rather than just watch and hear audio?
For me it's because the text comes before the actual dialogue. Why wait to hear what they say when you can read it first?", 'I only use them for times when I cannot understand the spoken dialogue. Brits are sometimes hard to understand depending on their dialect, and they use words which I do not recognize. Sometimes the music drowns out the dialogue. Some directors like to let everyone speak over each other .Assuming the subtitling is done correctly, it will be in high contrast to the surrounding environment. After all, they are meant for people who either can not hear or can not understand the dialogue. That high contrast is eye-catching, and help direct the viewer to read them, so they can follow the story just like anyone else. This can cause a disconnect when the written dialogue is changed from what is being said aloud, which is why most people that don't need them turn them off.
how does the restaurant get the tip from my card when they have already swiped it?
In the states , is it not common to punch the tip amount straight into the terminal when you pay by card?", 'Short answer. All payments in an EDC system are finalized when the batch is settled at the end of the business day. Until that batch is settled, all payments are adjustable and when a tip is inputted into computer it simply adjusts payments. When aforementioned batch is settled is when the transaction details are sent to companies. Source: Restaurant General ManagerWhen a card is swiped it's just an authorization. Basically, it's a real time message from the merchant to the bank to see if there are funds available to cover the purchase. That authorization will hold the funds . Settlement is the "batch" process to complete the transaction and initiate fund transfer from cardholder bank to merchant bank. Typically this is done end of day but some small merchants might wait a day or two. Settlement will make the authorization drop and replace it with the actual transaction. The settlement matching allows for variance in the amount BUT if there is a charge-back situation the merchant may lose any amount above the actual authorization amount. To prevent this, some restaurants with authorize for more than actual amount - up to 20% to help secure that tip amountWhen I worked at "Australian Steakhouse" what happened was you would swipe the card, make sure it works and leave the check open then once they give you the tip amount that's when you go back to the computer and punch in the amount then finally close the check. Then at the end of the night the manager and head wait would finalize everything.
I hope this isn't too obnoxious... ELI5 The 2012 US Presidential Candidates
Well son, there are two political parties, a mommy party and a daddy party. The mommy party is the Democratic Party. They want you to do well, but also want to make sure that the government will always be there to take care of you. They believe the government should always be involved and help you make the correct decisions. The daddy party is the Republican Party. They want you to grow up to be big and strong so that you can take care of yourself. They think the government should keep away our enemies and only help those that truly cannot help themselves. They believe that the government should leave you alone as much as possible. So who's your favorite, mommy or daddy? Also, [this site].
What is hyper inflation?
I have yet to see a proper layman's term explanation so I'll give one. The more money a government prints, the more diluted the value of its dollar becomes. This dilution causes you to need more money to achieve the same purchasing power you had prior to the government printing the money. Hyperinflation is this on a large and rapid scale.
The apparent increase of police shooting unarmed people
In the past, the cops would just lie or lack of video could shed enough doubt about what went down. Now, between dash cams and body cams on officers and everybody carrying smart phones that can shoot video, there's a much greater likelihood of video evidence. And once we've got some proof of what actually happens, then the other incidents are taken more seriously even without video evidence.
Why can I eat an entire chocolate cake in one sitting? What happens to all the surplus energy?
Ok, so 5000 kcal in a sitting. There are about 9 kcal per gramme of fat according to my food-scientist-Ph.D. girlfriend . So that's 555 grammes of fat. Fat has a density of 920 grammes per liter, so that's 6 dl of fat. Now let's assume this fat is spread out evenly over your entire skin surface, which is about 2 m^. That makes the fat layer about 0.3 millimetres thick. Wolfram Alpha tells me it's about four times the diameter of a normal human hair. So your body can pack on quite a few chocolate cakes before you can tell a difference.
Why does youtube buffer videos in all ¨P's¨ but when i'm watching porn it works flawless?
It has been said that your ISP is actually using a different server to route YouTube videos and it can't handle the load. I wish I knew the terminology to describe this. There is a fix for it as well, but I am of no use. I found it a while back with google. Check this out_URL_0_
Why can't we order donuts like we order pizza?
Although there are places that deliver donuts, it is pretty rare. One reason is that it is harder to make money delivering donuts. Many times when a pizza delivery guy leaves the store to make a delivery run, he is delivering 2-3 orders to different locations, each order is $15-20 after delivery fees. I don't eat many donuts, but I can't imagine many people spending that much on donuts. And if you did charge that much for donuts, I think the demand would be pretty low.I would buy some!!! Here in Canada, if I could order instead of walking out in the cold, which I often do Then there's the temperature issue. You can pick up a dozen donuts that were baked 5 hours ago. Who wants to pick up a pizza that has been under a heat lamp for five hours? This creates demand for a made to order pizza. Consumers usually don't mind eating cold or stale pizza later on, as long as the initial order was pretty hot and fresh. With the exception of breakfast in the office, there's not enough demand to justify a business that delivers donuts. edit: more details ", 'You could open a "Bakery" and deliver edibles in a state where it's legal.You could call it "High Cuisine" or something like thatSounds like a great idea, go for it. Noone has tried it yet.
How can a country survive without government?
There aren't really any historical precedents and the closest contemporary examples sure don't look good.A structure ballistically similar to a government emerges. A person or people are at the top, usually the people with the most guns, and ranks, levels and hierarchies trickle down all the way to the bottom. Somalia', "No, because then it wouldn't be a country. It'd be an area where people live.
Why does everyone hate Comcast so much?
Comcast is a rats nest of slapped together bureaucracies that don't interact with each other and provide unreliable service. Because most people have only one or two real choices for who provides their internet and TV, Comcast has no incentive to spend money to make their company work better when it would result in no additional income/revenue. Their only real competition in most areas also has no incentive to drastically improve service because that would cost money and set off an arms race, so people end up paying a lot of money for unreliable service to a company that could care less about ensuring their customers are happy.Comcast uses the tried and true DMV method of customer retention: threats, fines, and the only game in town. These fuckers pissed me off so bad a few years ago that I went off the grid and used terrestrial HD antennas. Fascist assholes.
Why are there rules on war?
My take on it is this: If you use whatever means necessary to eradicate your opponent then that is inviting them to do the same to you. Also, imagine that if a country went to war with another and used nothing but chemical weapons, but *lost*. Just imagine how much worse that country's inhabitants would be treated by the country it attacked.Depends on who is fighting. At its most primal, there are no rules. The whole point of war is to make the other guy stop doing whatever it is you do not like that he is doing. Sometimes you might be the attacker to stop him doing something, other times you might be the defender stopping him from attacking you. So in the end, there are no rules as to what you can or cannot do to make him do what you want. Now there are some agreed upon rules.-Do not kill medics-Do not kill reporters-Be polite to prisoners-No assassinations-No blackmail-No poison-No civilian deaths Basically anything that a rogue from DnD would do, dont. The "rules" of war come down to, make the people who said they want to fight, fight. Then after the people who signed up to fight finish fighting, let everyone go about their day with the victor being able to tell the loser what to do.When I was younger, I used to thing that rules of war didn't make sense. I would think: * if they can make rules of war, why can't they just make a rule against war?* if we make war rules as if it's a sport, why not just play a sport to settle things?* why do people have to die to resolve world issues?
How was Binary Code "discovered" in the 1600's? What were its applications?
Binary is just a number system based on 2 symbols instead of 10 symbols. Questioning assumptions about why we do everything based on 10 is a pretty natural question. It's not at all surprising that a mathematician investigated the concept a bit without any practical applications. It's very common for them to reduce things to the simplest possible form to find general rules.
If rounds can easily pass through car doors, why do police use them as protection?
In addition to the other answers, some but not all police cars have ballistic panels in the doors. It's like another thicker layer of bullet resistant vest, and it can stop some rounds, and at least slow down others.
What caused college degrees to become equivalent, or have the perception of being equivalent, to what high school diplomas used to be?
1. The bar on high school education has been dramatically lowed over a period of many decades. Political, economic, religious, otherwise ideological forces have conspired to impose their wills on curriculums which has lead to entire subjects being eliminated from diploma requirements and questionable changes to what information is taught and how. If you take notice, it's almost impossible to find a college that doesn't automatically shove people through basic education courses like algebra anymore because it's just rightly assumed that the overwhelming majority of people did the bare minimum to get their diploma and thus will not have the necessary information to proceed with true course work. So one answer is that college degrees now basically serve to provide what public education used to, and rightfully still should. 2. Changing economic circumstances have dramatically altered the needs of the work force. Go back even as recently as 30ish years and you can still find a fairly robust industrial economy in the western world. Unskilled people of little intellect could reasonably expect to earn, if not a decent living, at least a passable living so long as their backs were strong enough and their will to work resolute. Today that is simply not the case. Automation has retired a great many basic laborers and is poised to mass retire far more in the very near term future. Globalized distribution models mean more raw products can be produced in centralized locations and shipped all over the world, erasing the need for each nation to have individual parts of industry for themselves. Simple, unskilled labor jobs are on their way to disappearing, service sector jobs either cant or wont provide a living wage to their employees, and the jobs that can provide living wages are increasingly in fields where you can't just wander in off the street with a strong back and a plucky attitude and succeed. You need education to succeed in these fields well beyond the already devalued high school diploma which has made college degrees something more of a standard bar for entry.
Could I live on a diet of protein shakes and vitamin supplements alone? Why not?
[Supposedly] but I wouldn't want to. Fiber and all essential micro and macronutrients would have to be included for long term health. I think I'd literally get sick of it though.
Why are all the celeb naked pictures allowed on reddit but there was such a drama surrounding Zoe Quinn?
Well the main point about the Quinn thing was the danger of doxxing/a witch hunt. There is/was a lot of anger directed at her, and users on reddit and other places on the internet have been know for finding out private information about people, sending them death threats via PMs via PM or their phone, sending SWAT teams to their homes, accusing people of doing made up crimes etc. One of the [few reddit rules] forbids the sharing of private information, or even gathering that information by going through a users post history to prevent exactly that. Since none of those people are in direct danger and their PI isn't being shared, it seems like it's up to the moderators of a subreddit to remove that content. And some subreddits have been doing exactly that, either because it's not appropriate for the subreddit or out of respect for the women who's pictures are being shared. ). /r/gaming was in the midst of that controversy, so it might interest you to read [their statement] about that situation and why they did what they did.Sorry, late to the discussion. Who is Zoe Quinn?Because no reddit admins know celebrities; a few /r/gaming admins knew Quinn and other targeted gaming journalistsBecause the drama that fueled that situation was mostly in part due to maintaining journalistic integrity, while certain parts of it had feminism briefly injected. It dealt with a lot of touchy subjects, whereas for celebrity nudes we're all so immune to seeing them it's just like "oh, so that's what they look like."', "Because people think celebrities are fair game. If you're famous for being in movies then we're entitled to see every aspect of your life or something. If someone stole your nudes, it's your fault for taking them.
How are train engines able to pull enormous amounts of cargo?
I'll also add that it doesn't take to much effort to move a fully loaded rail car. You can actually move single rail cars by hand with a rail car mover . Also, trains take forever to get up to speed. I've actually driven one for a short distance before and acceleration is pretty slow.
how do hunters do more for the conservation of species than anti-hunters?
Hunters buy hunting licenses which are used to pay for programs to ensure that those species do well. The hunters themselves can also be important to prevent overpopulation by declaring it hunting season when there's too many animals.
Why is facebook stock falling? It's not like people have stopped using Facebook and they still make a profit.
Let's just back up for a moment **What is a stock price?** It is a ownership share in a company. It is a small portion of the value of the company. If, hypothetically, a person wanted to buy all the shares in a company, that is at least the price they would have to pay, just as you wouldn't typically resell your concert tickets for less than ticket price. **How do people figure out how much it is worth?** How do you calculate how much your house is worth? You see what the going rate for the land is in your area, you look at the state of the building, you look at what the **potential** is for the property, and many other factors. Well all these factors add up and you can get an idea how much *you* would pay for a house depending on how you deem which factors important. Company stocks are a bit like that too. A stock price should, in a nutshell, represent the total of the company's assets, its future potential, its tax and contract liabilities and a whole bunch of other factors. Now it is the future potential that people speculate on as, unlike assets, this can be more subjective. When it was floated, a lot of people were probably expecting facebook to haul in more profits and be a more viable business model than it is. This is understandable, as sometimes you never know what is going to happen. It has declined in price because it hasn't delivered on those earlier expectations. Thus, it is possible for a company to still turn giant profits and have their share price collapse because relative to what was expected of them before, they are not doing as well.
The controversy around the Kennedy assassination
An interesting theory [states that Kennedy was not Lee Harvey Oswald's primary target]. There is no proof either way, otherwise there would be no controversy. The evidence known as of now, leads me to believe that Lee Harvey Oswald was the lone shooter. But, that's just, like, my opinion, man.Jack Ruby apparently killed Oswald to prevent Jackie from suffering through a trial. This of course, is most likely bullshitThe first clue needed to see there was a conspiracy for any event, not just the Kennedy assassination, is to see who benefited from the event taking place.If you've got a lot of time to spend on this, I'd recommend reading *Reclaiming History*, by Vincent Bugliosi. It's a brick of a book, but I enjoyed it. He goes over all the theories and debunks them. Or claims to. He is a proponent of the single shooter theory, so that's the perspective you'll get it from.When talking to people of my parents generation, they all remember the exact moment that they were when Kennedy got shot. Looks like everyone has their alibis.
What would happen if everybody took all of their money of their bank accounts
A bank never has enough cash to cover all its accounts. By law, the biggest of banks are only required to have 10% of the money that's on the books available for withdrawal. Smaller banks don't have a minimum at all.
of the sun blew up we wouldn't be able to tell for 8 minutes. Would we be dead before we knew? Or would we be able to watch the sun explode?
I'd like to add some other things to consider. Our sun is kind of an average star and it's future doesn't involve explosions. In about 4 billion years as the hydrogen fusion winds down, the outer atmosphere of the sun will expand to many times it's current size. It may even grow so large that it envelops the earth. It will get larger, redder, and dimmer over billions of years. Consider that mankind in all of our history and pre-history has only been around for 100,000 years or so out of the 4.5 billions years or so the Earth and Sun have been here. We will be long gone by the time this happens, perhaps wiped out, evolved into something different, or maybe even colonizing other worlds. 4 billions years is a very long time. In the final years as the sun switches over to fusing helium, and then finally to carbon and oxygen, it will cast off it's bloated atmospher and become a white dwarf in the middle of an expanding planetary nebula that will be seen for thousands of light years. The planets will likely be vaporized at that point and the pot will be stirred, seeding the next worlds with the stuff of stardust, and all of the elements to create new stars, new planets, new life. It's a cycle of birth, death, and renewal that will go on long into the future. Our own solar system and sun formed in such a nebula, with the heavier elements like iron, uranium, lead, formed in still more ancient stars. I often think about this when someone confides in me that they want to live forever. Actually living forever would be terrifying, as the universe around you becomes alternately cold, then fiery, then life sustaining, then fiery, then cold, over and over until the last star in the last galaxy has shined it's last light. To me that is far more terrifying than the thought of our sun growing old and devouring the planets.
What are the science protesters protesting?
I was one of the 'science protesters' marching yesterday. I'm not going to discuss the pros/cons of science etc. in this comment because it's not answering OP's question; I'm just going to objectively explain why there was a protest. Our message was that we firmly believe that scientific input is critical and necessary for informing government policy-making at any level, and that scientific endeavour needs to continue to be sufficiently funded - for the better of policymakers, lawyers, farmers, you, me, and the rest of humankind. So what specifically led to this protest? Mainly the Trump administration's treatment of climate change concerns, shutting down the EPA and officially removing any acknowledgement of climate change from the White House website, and the slashing of funding to various major scientific organisations in the US. However, similar things have been starting to take place in other countries , which is why this protest took place in many countries around the world.
Why are motorcycles so poor on gas compared to cars?
Huh, never thought of it that way. Maybe it's an economics thing, where the manufacturers see 50mpg on a motorcycle as *enough* of a selling point, that it would take more money to invest in making them fuel efficient. Ultimately, maybe it's just a dollars and cents thing to make more money?
What is the basic argument opposing net neutrality? Not from the corporations who stand to benefit, but from regular people.
In theory it would be used to put services like E-mail or others which are not as time crucial as streaming or online gaming on a lower rank. This way the Time Crucial applications gain speed which is highly appreciated, and the services that don't need to be fast are a bit slower, which no one really notices.The lure of profit drives innovation. Net neutrality could reduce profits and reduce the incentive to innovate in the internet. For example, AT & T might not invest the millions required to get fiber to every house if they fear that net neutrality reduces their ability to profit from that. Hello net neutrality. Goodbye gigabit internet.I think that the arguing point is that they can allocate more speed to things like Netflix, that need and less to facebook which doesn't use as much. This isn't my opinion just what I've heard people argue.
Why isn't there a viable alternative to Ticketmaster?
I have not delved into their finances except at a high level, but one thing I find curious is that they've lost money for the past 4 years. Their revenue continues to climb at an enviable pace but they still lose money. I did not look to see what factors are driving these losses but it's something to consider. If their losses are real, meaning that they are not carrying forward prior losses or some other accounting issue is in play, then it may be simply that the market can't afford another player. Don't forget, pricing is based upon what people will pay, not what something costs. So it's possible here that Ticketmaster can't charge enough to cover their costs which is preventing anyone else from entering the market to compete. Note: I am well aware of the perception that people have regarding Ticketmaster and I've honestly never used them so I don't have an opinion. But maybe the answer isn't something we expect it to be.
Why did NASA end the space shuttle program? Are they still doing other things?
I currently work for NASA as a spacecraft operator. We ended the manned shuttle program because it was costing way too much money to maintain the shuttle for every flight. The craft was costing in the hundreds of millions if not billions to re-launch every single time. It was decided that we just couldn't afford it. NASA, as well as many other companies like SpaceX and Virign, is currently in the process of developing new methods of human spaceflight. This is just a gap in the program, and NOT the end of space exploration. We absolutely are still doing other things. Yes, the manned program was a huge portion but without that load we can now put more money into unmanned exploration. We'll be creating new spacecraft to monitor the Earth, Sun, and everything else that you can imagine. This isn't the end of NASA, not by a long shot. This is just the beginning.
Why cant the brain tell the diaphragm to stop hiccuping?
I can control my diaphragm to a certain extent. When I get the hiccups I only hiccup once or twice before getting it under control. The trick is to breathe in and out nice and slow and relaxing. Don't stop breathing in our out if you hiccup, just finish the in our out breath as if the hiccup did not happen. The key is to relax. Hopes this helps someone else.
How can a lawn survive a full winter covered by snow, but start dying and turn bright green from 2 days of being covered by a tarp (or something similar)?
Because it takes nature a full season to throw it's tarp over the grass. The grass has almost 3 months to prepare. It takes you 10 seconds to put the tarp down. That's not enough time for the grass to hold it's breath.
Why does grass make people itchy?
When we sense something interacting with our body on any level, it registers. Lying in grass, for example, creates many separate interactions with your skin and a foreign living material. I believe human skin on skin doesn't register an alarm or itch of any sorts but interactions with plants, fibers, feathers, etc., anything that isn't human skin, will create a memory in our nervous system that alerts our brain that something has touched us there. It is a way to keep us aware that we need to check the area in case it could've been something bad, b/c often times, a simple insect can feel the same way and have much worse consequences, thus we have developed a system over time to alert ourselves of potential problems. Most of the time, like in the case of lying in grass, it's a harmless alarm that we can consciously override if we have any will power. The weak willed become addicted to eating, drinking, smoking, etc without the will power to stop/moderate and the nation declares these addictions diseases, when in reality, these people just eat and drink too much, and every last itch they get needs to be scratched. Yes, this was divergent, but the crux of the question was covered fairly well I hope.
Why are there seemingly no sound restrictions on motorcycles?
As a Harley rider I have ridden quiet bikes and loud bikes. While people do tend to notice you more when your bike is louder I also try to be respectful of the other people in my neighborhood. One aspect that nobody else has brought up yet is performance. A properly tuned bike with an open exhaust rinse better then a bike with stock exhaust. That's why most performance cards, trucks, etc after all louder than their stock counterparts.> I can't wait until all these fucking things are electric. I'm a motorcycle rider and I agree. I would just call them "awesome things" instead of "fucking things". ;) It's not just the noise. Electric motors give you maximum torque at any speed. An electric bike would take off faster than the fastest regular bike. I say this as the owner of a conventional bike with one of the best 0-60 times ever. An electric bike would be whisper-quiet, and incredibly fun to ride.There are many restrictions, just can't enforce them unless the cop happens to be right beside the **'er when he/she is revving their POS Harley up to 130 decibels to strut their stuff. At idle the bikes are bearable, but whoa, when going by someone walking you hear them revving it up and blasting my ear drums. Actually hate this aspect of bikers. I just want to tell them some very unpleasant things as this is ridiculous.
Why is food that is bad for us so inherently tasty?
Unfortunately at the time that modern humans were evolving, food sources were scarce. Thus it was more advantageous for an individual's survival and reproduction to eat food high in energy. Now that we have an abundance of food, we're experiencing what is called an evolutionary lag- that is, we haven't adapted to our current environment of abundance. We crave high sugar/fat foods when it no longer gives us an advantage. This is when an evolved trait becomes maladaptive. That said, I will go consume a bag of chips.
Why does the *save* button of most computer programs is still a floppy disk?
It's an example of [skeumorphic design]. It's just the icon we know and so it has remained that way.
What are current active research areas in mathematics? And what are their ELI5 explanations?
If you ask a Math question and don't know the answer, that's an open area for research. Heres one for you: what's the most efficient way to divvy up an N-dimensional sphere with smaller spheres, each of equal size
why do cats and dogs have to touching me when they sleep next to me?
Cat person here. My cat wants to sleep on top of me, or as close as he can get. I am pretty much convinced that this is a comfort thing. If I talk to him and pet him as he's settling down, he gives the cat 'love sign' of slow blinking at me.
How does striped toothpaste keep its shape within the bottle?
It's a paste, not a liquid and there is no empty space in the bottle so there is no room to move enough for it to mix so it keeps the shape.
Why would you sue someone who has no money for millions of dollars?
I don't see this mentioned yet, but I think another reason is about setting a precedent that will actually scare people away from repeating the offense. Millions of dollars might actually have an effect on peeping celebrities, whereas a few thousand wouldn't stop people.
- The Importance of the Theory of Relativity
It means that there's no absolute concept of time or distance. That is, if you see that something's 1 meter long, it might be only 1/2 a meter long to someone else. And if you see something that takes 1 second, it might take 2 seconds to someone else. This isn't just a weird perspective thing; to that other person, it *actually is* 1/2 a meter long and *actually* does take 2 seconds. This is significant because well, because it's what happens. If you assume that something like a GPS satellite will observe the same times and distances as you, it doesn't work right, because the assumption is wrong.
Why would countries publicly display their military information? (infantry, tanks, nuclear warheads etc.) Doesn't that just help rival countries to make a plan of attack?
The point of a strong military is less to wage war than prevent it. You want to display strength so others won't attack you.
Why do humans need to be taught to swim and other land animals like a dog can naturally swim when put in water?
Like tury345 touched on, it has to do with the evolutionary need to do so. Humans don't require the ability to swim because we have evolved on land. As species evolve, they grow more adept at things that are necessary for survival. Therefore, due to the fact that humans don't absolutely NEED to swim, they never developed the need to innately do so.Most humans are capable of swimming in salt water without any training.
Why hasn't the US government closed down The Deep Web and or try to block it from users?
Because shutting down the dark web is hard. Here's what they can do * Find and block the IP addresses of the websites that are creating illegal activity. * Have ISP's create a whitelist so you can only access websites they approve of.* Block all secure communications , and monitor your traffic. In the USA, the federal government will never do any of those options. And you can't shutdown the whole darkweb because it's made up of too many networks and computers .
