How do brands like "Great Value" make such similar products to name brands?
|
As someone when does sell private label items. Sometimes the only difference between name brand items is the packaging. There are occasions that the name brand supplier will sell the private label brand as well. Overall it's still a sale and they need less advertising money to support the private label.

How to count time signatures in songs
|
The thing that always confused me is, why is 3/4 time not the same as 6/8 time. Short answer, as far as I could surmise, is that it's just an unspoken convention. People know the 3/4 rhythm, and they know the 6/8 rhythm, and you can't work out the difference just by doing the arithmetic.

How are [most] people able to determine whether a person of the opposite sex is old enough to be sexually attractive?
|
You don't. Adults are usually attracted to sexually viable mates, meaning people who have passed puberty . Physical maturation does not necessarily mean mental maturation, however, which is why kids are often protected by statutory rape laws. Puberty in both boys and girls has actually been starting at younger and younger ages, probably because of health access, better nutrition, and food supplements.

Why is Hitler's popularity rising in India?
|
I just recently got back from Nepal, and the more educated locals said it was due to the fact that they were so far removed from WWII, and therefore Hitler's atrocities. They were simply not educated in the facts, however they were reading Mein Kampf, and saw that as a compelling and authoritative piece of work, something only to be written by a smart man meant to be respected. They likened it to western people casually revering Alexander the Great because we don't know much about him but his conquering abilities , and forget his insanely violent reign.

Why is there a delay between newcasters using a satellite feed when we have video calling such as Skype or Facetime that is much more instant?
|
Skype, and all internet based services are effectively hardwired for the majority of the connection. There are cables across the ocean, there are hardlines between your home and the ISPs, etc. Cellphone towers are hardwired to the landline phone companies etc. The news casters are relaying the information directly to the satellites from location and then routed through a relay system across the globe. That means lots of errors are going to show up in the transmission. These errors are corrected for with additional 'redundancies' which reduce transmission problems such as repeated information and headers and other checks, but these checks also increase the amount of time required to send data.

Why do people turn down the music when they're close to locating a street or destination?
|
Depends how loud you have it I suppose I usually play mine pretty loud in the car so I turn it down out of respect for the people living around where I'm headed.
|
Why do we generally perceive people who are overweight as "less attractive" than people who are slim?
|
Our attractions have to do with the potential to give birth to and raise healthy offspring. Someone who can't take care of themselves isn't as likely to do well with the added responsibility of another smaller human.

What has happened to this subreddit?

Why does it feel like I'm going faster the closer I am to the ground?

Perspective. It's the same reason street signs move past so quickly, but mountains or buildings in the distance move slowly. It's just on a different axis than you experience when driving .

How come full siblings share only 50% genetic with each other and not 100% since they both have the same parents?
|
There's also crossing over to consider. The 46 chromosomes in a human are arranged in pairs. During the process where cells become sperm or egg the legs of the pairs kind of wrap around each other and trade little pieces of genetic material. This is called crossing over, it ensures diversity. It's another reason why siblings look different even though the genetic material comes from the same source. Even if you got the same chromosomes from each parent as your siblings, the chromosomes themselves would be different. No two egg or sperm are exactly alike, not even in the case of identical twins. That happens when a fertilized egg splits into two embryos during early development. I mean statistically speaking they could be, but like someone earlier said, the chances are astronomical.My husband comes from a small town where they have something called "double cousins". This means two siblings marry two siblings, and the resulting offspring are genetically closer than usual cousins. For example: Bob's cousin is George. Bob's father is George's father's brother, and Bob's mother is George's mother's sister. Does this make them as genetically close as siblings? I'm never sure.

Why does the British press hate Jeremy Corbyn so much?
|
A portion of British papers are owned by News Corporation, which is of course founded by extreme conservative Rupert Murdoch - so they spew his hate-filled political rhetoric by default. That goes for other papers too; they're, for the most part, owned by capitalists who would find themselves actually paying tax under Corbyn .

What is the high pitch sound that happens when I turn on an older tv?
|
Now that we know about why CRTs do it, does anyone know why an LCD TV might make a similar sound? I have one in my dorm room and a few seconds after I turn it on it will start making the noise, then stop about 30 seconds later. It's a lot louder than I remember CRTs being and I have no idea what's causing it.You used to be able to walk into a house and instantly tell if a television was on even if the volume was off. There were a couple HP crt monitors that would get out of sync and the tone of the high pitched noise would change, and we learned at hp desktop support that the fix was to smack the monitorIts the 30,000 volt capacitor whistling as it turns on and discharges.It's audible because the line sync signal is prevalent throughout the circuitry of the TV. Some of it running at high currents to drive the flyback transformer and horizontal deflection coil. Any conductor carrying AC current vibrates and thus can be audible if the current is high enough and the frequency is in the audible spectrum.

What do people do when there's 3 or 4 or more feet of snow out?
|
Keep in mind that people have been living for thousands of years -- i.e., long before the Industrial Revolution, much less motor vehicles and electronics -- in regions where three or four months of snow is standard, and accumulations of three or four feet on the ground is common. If you live in a place like that, you have chains on your tires. If you live in a city, you can expect at least all the main thoroughfares to be cleared pretty quickly -- it's a regular part of the city budget. And a proper snowplow can easily handle six-foot drifts. If there's a blizzard coming, people who have lived there all their lives know to keep a stock of food and water handy, and firewood or propane heaters. And if it's just snow, you can expect all the kids to pull on their boots and grab their sleds and ice skates. I'm old enough to remember walking to school in blowing snow, through two-foot accumulations. They never closed the schools merely for that. I now live in an area on the Gulf where major hurricanes can be expected every couple of years, and we all know how to prepare for them and how to deal with the aftermath. But I've also lived in the upper Midwest, where there was heavy snow every year, and in the arid Southwest, where heat was much more a problem. Don't underestimate the ability of humans to adapt to whatever climate they've got.

Why are the words "eleven" and "twelve," so different from the pattern of thirteen, fourteen, fifteen, etc?

Semi-related, my six year old asked me why we don't say teen-three, teen-four, etc, given how we follow that pattern for twenty and beyond.

How have Spain and Greece's unemployment rates gotten so high?
|
Greece was borrowing tons of money at low interest to run its economy. They were able to do so because they were a member of the eurozone, which made them seem stable, and because they were completely lying about their finances. Once it because clear they had borrowed more than they could ever hope to pay back, people stopped loaning them money, and their economy toppled. Spain wasn't nearly as reckless as Greece, but they were borrowing lots of money too. When Greece got in trouble, people started to think twice about loaning out money, and suddenly Spain and other countries had to pay a lot more to borrow money, getting them into trouble as well. This made it more difficult for companies to borrow money, and the gloomy outlook means people don't want to take chances starting new or expanding existing companies. What's more, strong labor protections in Europe make it difficult to layoff employees once hired, making companies even more hesitant.

why do so many people run for president when it's obvious they aren't going to win?
|
For Sanders: He knows he has a very outside chance of winning. but his purpose is to show the more progressive/socialist/liberal ideals compared with Clinton, which helps shape the policies laid out after the primaries, as the nominee needs to appeal to all of their side, not just the majority. For Cruz: He will get paid to do speeches or endorse others as a major Tea Partier, and like most candidates, rarely needs to put his own money in, as people donate money for him to do whatever he wants. He won't meaningfully shape the debate because there's simply too many people, but he gets his own personal benefits from running. For others:Either it's one of these two or a combination and blend of them.

Why aren't people buying the $1 houses in Detroit?
|
I'll ask my own question, OP. Do ***you*** want a house in Detroit?", 'Hopefully the hivemind can help me out with the feasibility of this plan: * Step 1: Buy several city blocks in Detroit for cheap.* Step 2: Bulldoze. EVERYTHING.* Step 3: Build a giant castle, complete with walls and a moat.* Step 4: Offer free housing and enjoy your new role as King of a city within a city. How much do you think this would cost?You can murder a couple people in Detroit and get away with it. Miss a payment, fuck up on a property code, piss off the tax man and you will be hounded and hunted down by the man for all eternity.Having lived in Detroit for years, and having left in 2007, I can confirm that it's because the houses are in Detroit.

How/why do different alcoholic drinks effect you differently if it's just ethanol that makes you drunk?
|
I hear people talking about this all the time, but I've never experienced it. Ethanol is ethanol, there's no reason why there would be any variation in effects between different drinks.
|
Why are people more comfortable sleeping with a blanket over them even in warm climates?
|
This is the first time I've ever heard of this although many people seem to agree with it. I sleep without a blanket a lot in summer. It is simply to hot to have one on. I don't feel any less comfortable with a blanket off then on.

Why is it that you need a permission slip to watch R-rated movies in high school, but can be assigned to read books like A Thousand Acres in English class without anyone batting an eye?

When I was in High School I wrote a paper on 'homoerotic themes in mobydick' I had to get permission from the principal, I just liked the shock value.

Why do I need insurance? Couldn't I just deposit an equivalent amount into an account each week?
|
> Couldn't I just deposit an equivalent amount into an account each week? Only if you assume that you will never make a claim for more than your account can cover. The point of insurance is to pool risk, so that the amount any one person pays in premiums is, *on average* more than the insurance company expects to have to pay out. Some people will pay premiums and never make a claim. Some people will pay premiums and make claims that are thousands of times larger than the premiums that they've paid. The goal here is to prevent cases where people go bankrupt because they run into an incident that is so expensive that they have no hope of ever paying it off without insurance.

Before diapers and the like, how the heck did early man keep babies from ruining everyone's day with their angry baby excretions?
|
I lived in China for eight years, and there it's not very common for babies to wear diapers, especially in rural communities. While they are being potty trained, most babies wear pants that have a split in the crotch/butt area so the pants don't have to be taken off every time the kid has to go, and if they have an accident, theoretically it won't get on the pants. The parents/grandparents basically teach them to pee and poop on command with whistling noises while they hold them over the bushes/toilet/trash can. By the time they are two, most Chinese kids have already been potty trained for a while.Before diapers shit was everywhere. Not just baby shit, everyones shit. There was no central plumbing and people shit in buckets and literally tossed it out the window. Shit used to flow through the gutters of the streets. For frame of reference see modern IndiaDogs have been coexisting with humans for a really long time to each other's mutual benefit… if a piece of food hits the floor, every dog owner goes "don't worry, our furry vacuum will get it". Anyone who's ever had a dog & Baby in the same house, knows how much dogs love to get into dirty diapers. The disgusting math does itself in this puzzle.I was in rural Southern China about seven years ago while traveling. I don't know if it's universal or maybe it was just this area but The babies were usually just naked from the waist down. It was not unusual to see mothers holding their babies over trash cans as they got the job done.

Why isn't HTML considered programming?
|
Because HTML doesn't allow you to change behavior. It only allows you to mark the content with a tag, depending on the browser to whatever preprogrammed behavior for that specific tag or set of tags. Programming is cooking with ingredients. Markup is ordering food food menu item #5", 'Remember, your reddit comments are done in *markdown,* which is, like HTML, a mark**up** language. You can't exactly consider commenting on reddit "programming," can you?

how does going to war make a country richer?
|
As others have said, generally it doesn't. Especially now that pillaging is out of fashion. The one way it can *sometimes* make money is fixing the too-many-people-sitting-around problem. Too many people sitting around doing nothing? Send some of them to war. Put some of them to work building stuff to replace the stuff that's getting blown up. Economic activity and productivity increases due to people being gainfully employed. It would be much more effective to just have people build roads and bridges and schools. But that's difficult to get through, politically. You need logic and reason to convince everybody that government works projects are what's needed. You can use anger and passion to get people to go to war.

If I hurt my dog on accident, do they know it was unintentional?
|
I've been getting into dog psychology recently. One thing I learned is that dogs are animals that move on easily. Not only that they move on fast too. If treated correctly, a dog that could have been abused for 6 years can quickly move on and be comfortable as well as trusting around its new owner. A little thing such as accidentally stepping on a tail, poking in the eye etc is nothing. Apologizing I would say is pretty important, however you don't need to spend a lot time. Just say sorry and pet on the head, not on the underside and let it go. Make sure to use a kind tone of voice to let the dog know it didn't do anything wrong. You must also stay calm, getting nervous or shocked will pass the energy on to the dog", '"Even a dog knows the difference between being kicked and getting tripped over." Oliver Wendell HolmesDogs do remember harms that are done in earnest. They forget accidents.To expand on others Dogs really are uniquely gifted at reading human body language. So much so that they are the only animal to look at a humans eyes to judge intent. Smarter dogs can actually look at your eyes to get a clue on where a toy is hidden for instance. So even the uh, less smart breeds, can read enough of your body language to understand an accident when it happens fairly easily. Though that doesn't necessarily mean they won't be skittish of a similar situation in the future if it was a bit traumatic.

how do illegal drug prices remain more or less constant while everything else increases in price?
|
I knot that an ounce of pot costs more now than it did when I was in high school, almost 20 years ago. And it costs a **lot** more than when my parents were in high school 40 years ago. So yeah, I don't know what you're talking about. For pot, at least , prices have definitely not remained more or less constant.

Why does a photo taken with any type of camera look different than when we look at that scene with our eyes?
|
The retina of your eye has special cells called photoreceptors. These cells take in light and send a signal to your brain telling you what you're seeing. These photoreceptors perform a similar function to the light sensors in a camera. But, the light sensors will never work exactly the same as the photoreceptors in your eye. They are going to record a slightly different image from what your eye sees. Also, there is a lens in front of the light sensor just like there is a lens in front of your retina. The two lenses will never be the same either. But, even if the camera did manage to record the scene exactly the same way as your eye does, you still have to display that picture somehow. That either means printing it out or displaying it on a screen. Neither of those methods will ever perfectly recreate the scene exactly as you would have seen it if you had been there.

Why do we allow the president to pardon people?
|
Some of the things in the constitution are remnants of another time. The fact that it's in there doesn't mean it's a good idea. Not all of the stuff in the American constitution makes perfect sense in modern society. Not saying it's the case here, but it's not necessarily there for a good reason or above critique.In general the pardon power is good as a safety valve. I would support an amendment that limited the pardon power such that it did not apply those defendants where a conflict of interest with the president exists .

If Ebola is so hard to get why is there such a big outbreak?

It's not that big of an outbreak, honestly. Things that are really infectious in the past have been known to spread far, far, far more. The Spanish flu took out some 5% of the entire human species and the plague took something like 1/3 to 1/2 of Europe.

The election results in Australia and why so many Australian redditors are upset right now?
|
A quick wikipedia read of the guy's page does not help me, as an American, as he seems like a rather reasonable conservative by U.S. standards.They must be either.. A) Rioting in the streetsB) Still asleep Seriously, 39 upvotes and not a single explanation?', "Labor lost the right to govern this country Of course labour policies were better as they we planning on spending a lot more money than liberal, and while this is easy to vote for and this election has forced the Labour Party to make some ok policies it doesn't excuse them for spending 60bill on NBN and messing up the asylum seeker with no answer with how to fix the problem.I am a labor supporter but they lost sight of really helping the Australian people and ironically it was their last policy was so good as they were forced to appeal to the populous leading up to an election. The reason everyone is pissed!!! Is cause a lot of people voted for tony Abbott based on them favouring social conservatism rather than economic conservatism. Many students with fundamentalist upbrings vote liberal even though it is clear they will individually benefit more from Rudd . I think liberal is the correct choice at least for the next term because we need some stability I just think the reason they are in is not because people value the country over their individual gains just because they voted on only one policy and we are lucky enough that the economic conservative is also socially conservative in the election

How is it sanitary for doctors and nurses to wear scrubs on their commute to and from work?
|
In England we don't. The scrubs are provided by the hospital, we get changed into them in the morning and when we leave at night we leave them there for some industrial washing. Always clean scrubs, not to be worn outside the hospital. The same with shoes. We have theatre shoes provided by the hospital. We wear these just in the hospital.The sanitary nature of scrubs is not to keep contaminates away from patients, that is done with gloves and washing of hands. The purpose of scrubs is to keep contaminants they get at work from their normal clothing. So it is to keep blood, vomit, urine, fecal matter, etc off of street clothing. So there is no issue with them wearing the scrub on commute to work, and only an issue on the commute from work if they are wearing soiled scrubs.Nurse here. Most hospitals have you change into scrubs on site. Some don't in order to save laundry costs . A big misconception about hospitals is that they are clean. They are not. They are germ and bug hives with hopsital staff doing the best they can to avoid it. Most hospital acquired bugs are prevented by the fact we wash our hands a million times a day and use aseptic non touch techniques. More bugs are spread from bad family member hygiene and doctors ties than scrubs.

What is the purpose/meaning of the extra bit of stairs at the top of some British/Irish staircases?
|
> I had always wondered, for instance, about that strange, superfluous little staircase on the hotel’s first floor: it was put there deliberately by the director, who recalled such an absurd device in a real Edinburgh hotel. It also helped to exacerbate the sense of frantic movement. _URL_3_ No they are not common as the interview points out even the set designer found it absurd. It's also not uniquely British/Irish [just really poor] design work or a result of [stairs being a later] edition.

When is lineage determined for American born people today/ when do we stop saying we're 25% this and 50% that?
|
I assume that would be what your faily would be called if you moved **out** of the US. When you live in a country, it's usually assumed you are from there. Saying you're american when you talk to other americans, in america, is kinda redundant. If a person who used to think of themselves as 12.5% Irish and 25% African or whatever, moved to Ireland or to any african country, they and their future children would probably think of their family as coming from america :)", 'A big part of this is about identity and belonging to something.

How come cargoships don't run on solar– and windpower?
|
because it would take a huge amount of solar or wind to power them. they are very large and move at an amazing rate of speed. I don't know why more are not nuclear powered like some of our aircraft carriers though. I remember going to see the USS Yorktown in Charleston SC when I was a kid and they had a nuclear cruise ship docked there too. This was 20 years ago, so I don't understand why more are not powered that way unless it is government regulations or something of that nature.

Are you referring to time as the fourth dimension of spacetime? If not, some physics theories, namely string theory, work mathematically with more than 4 dimensions.

Dams .specifically hydro electric dams. Despite all the attention wind and solar is getting, it's hard to compete with dams but not every place is suitable for such huge dams in huge quantity otherwise we would have built them everywhere.They have very few people, little to no manufacturing and industry plus their geography is very well suited for hydroelectric energy generation.

Why do beer commercials advertise how cold their beer is as a selling point? Isn't that up to how i store it?
|
I work in a beer distribution center. Shit, it gets sent to us warm and it only has to be stored at 60 degrees. When it gets loaded onto the trucks, it sits overnight in our warehouse at around 80 degrees. Like others have said, it's all a marketing trick. It's a bunch of BS too. Like I said, it never stays cold like they want you to think. It doesn't even really matter all that much in the end though. The beer is fine no matter how we store it , it's pretty much just a placebo.Refreshing means water. The more refreshing, the more watered down it is.I like a cool beer as much as the next guy, but a beer isn't a good beer unless it's also good at room temperature.

If a one time infection by certain viruses (e.g. chicken pox) usually leads to immunity, why can other viruses recur in the same person countless times?
|
Well, this can be for many reasons. Viruses and other microbes change just as much as we do, so you may grow immune to a virus but some of that virus may change just enough to circumvent your immunity. Also, there are thousands of types of viruses to begin with, so we are at a disadvantage from the get go. edit: some viral infections can become chronic, meaning you always 'have' the virus in you, but it flairs up from time to time. This is actually what happens with chicken pox, a varicella virus, you can't usually get chicken pox again but you can get Shingles, which is caused by the varicella virus, which does not leave your body after the infection.It all depends on the virus. Some, like the one that causes chicken pox, tend not to mutate much so the body can build up an immunity that will remain valid. By comparison, the common cold is caused by a group of viruses that mutate very rapidly. You never get the same cold twice but there are an ever growing number of variants to get!', "It's called evolution. Some viron mutate their genetic code. Like Flu mutates a lot so we need a new shot every year. Other viruses like HPV or Polio don't mutate that much, so a vaccine from 1990 and one from 2015 will be just as effective.

How come Adobe does not support flash for mobile phones, tablets, and ipads?
|
think of it like his, if Apple made Flash work on the iPad, you could just go to a website and play it similar in quality with the native apps, but online. Apple would loose it's monopoly on the AppStore, for a lot of the casual games that a lot of people buy, and Apple could not force developers to pay 30% royality on each app sale.Apple has made the design choice to not allow Adobe Flash on Apple mobile devices because of stability issues. Apple has very high demands for reliability, and Flash is responsible for a large proportion of crashes on devices. They made the judgment call to remove the feature in favor of retaining a reputation of reliability and a stable user experience. Opinions vary on if it was a good callyou know, there are mobile phones and tablets not made by apple.

The reason WHY the NSA is targeting mass data instead if tracking individuals.
|
It's about finding patterns and being able to better predict the future with the data collection. Say they find a weird specific link to terrorist cells. Like falafels and they can sort trough the data looking for odd things that can tell them what individuals have a higher percentage of being involved in activity they want to track. So collect ALL the data and learn everything you can from it to establish patterns and common themes between individual people. Profiling basically, from a pool of everyone.

How a vending machine knows when you insert counterfeit money?
|
Legitimately, most of the counterfeit money I've seen at my job is printed off on printer paper. Printer paper in no way feels like the stuff American cash is printed on, and I'd almost guarantee most of the accepted counterfeit bills are accepted by careless and/or overworked cashiers. Just yesterday, a guy came in trying to pass off a printer-paper $100 at my job . Printer paper $20's were very popular at my old job, too, and I usually saw one or two taped by the register at the other stores owned by the same company - they didn't train their cashiers very well As for coins, they're all based on the weight and magnetic properties. You can drop a British 5p coin into a US vending machine, and it'll let it drop through - doesn't match the magnetic signature of any US coin, doesn't weigh the same, or anything, even though it's similar in size to a US dime. Drop a US nickel from 1864 into one, and it'll accept it just fine, though - the coin has had the same composition for that long, aside from in the middle of WWII, where silver was mixed in to allow for more nickel and copper to go towards the war effort. Same reason why vending machines take both the Susan B. Anthony dollars and the Sacagawea/Presidential gold dollars - same weight and magnetic properties, without an update from when some were programmed to accept them in the 1970's.

What do robbers do with stolen objects from museums? Why would anyone buy these stolen objects other than keeping them for their private collection?

Wealthy people like to have things they aren't supposed to, it is a power move, like look at this long lost painting that should be in a museum but here it is in my living room. These items are sold on a decentralized criminal underground comprised of many different people and places called the black market, where you find reclaimed goods and otherwise illegal things. Some of these objects can be used as filler pieces at a dig site to help boost someone's career, they can be seen as an investment that grows in value, some do it for superstitious purposes.

My friend just flew to Spain and had three disks replaced in his neck. It has been a big success. It is considered experimental here in the USA and his insurance wouldn't pay or even consider it. He played for it out of pocket. It was very expensive but he is happy with the results.

Is U.S. currency no longer backed by/worth anything tangible? What are the implications of "Fiat" currency?
|
US federal / state / local governments collectively require people and businesses to pay them literally trillions of dollars in taxes every year. People need dollars for that. Those tax dollars are mostly spent, not saved. If you want to do business in some way with the US government to get your hands on some of that spending, whether you're a high-tech company building spaceships for NASA or an 18-year-old looking to join the Army, you'll need to accept dollars for your services, because that's how the government is going to pay you. Plus most of the US economy, and many non-US-based parts of the world economy, also do business in dollars. People need dollars to participate in all of that economic activity as well. The sheer size of the system makes it stable and hard to change.

Why does Apple not build its own manufacturing plants?
|
There are a lot of good answers in here, but let's do it like we're five Let's say you want to make apple pies. You need apples, flour, sugar, etc. You have in the kitchen everything but the apples. There are many ways you can get apples: -You can go to the store to buy apples, but you want to make a lot of pies, so doing that every day would be too expensive. -You can grow apple tress in the back yard. The apples would be cheap, but you'd have to buy seeds and manure, you'd have to water the trees every day, and they'd be grown on your land where your Dad could see them growing all the time. -You can buy big barrels of apples from a big farmer that only grows apples. You get the apples today for a good price with minimal effort. The third one is the best choice. You want to be responsible for pies, not an orchard. The big barrels of apples in this case are the cheap labor and lack of oversight and taxes, and most of the stuff everyone else said.

Leasing a car for 6 months
|
The prior comments are very detailed and helpful, but leading is different in the US. Leasing is done by car dealers and is incredibly common. While long term renting seems like a terrible idea, there can be advantages. 1. In the US, dealers sometimes offer really good rates. For example a $199/month lease on a 20k car will cost you 7200 over 3 years. You are probably doing better than depreciation. Buying and running a car for 10 years is a better deal, but then maintenance, warranty, and reliability rear their heads. 2. Lease costs are easier to deduct for a business vehicle. Otherwise, you figure depreciation, etc. 3. At the end if a lease, the dealer is motivated to sell you back your car. Many have negotiated great deals at the end of a lease and you know the history. 4. If you shop correctly, you can pay less than depreciation and never have a car out of warranty. You don't have to worry about that 4000 transmission. 5. Mileage limits apply and a more common source of extra fees vs wear and tear. If you are conscious about your car, you usually won't get charged. My advice is to shop in continuous 48 for leases and inquire about 6 month rates. Look for advertised manufacturer specials. If the cost is too high, consider a 24/36 month lease. You may need a car for longer and you could even sell your lease. There are dedicated websites for this. Even if you sell the lease for a loss, it may be cheaper than the 6 month option. Consider buying a used car under warranty and then selling it back. You avoid the initial depreciation hit and don't have to worry about major failure. If you buy a 1000 dollar car and it fails, your replacement options are limited and expensive in Alaska.

If we sent a team to Mars, why wouldn't they be able to return?
|
It's pretty hard to launch a rocket with enough precision and velocity to reach a landing spot on another planet. We have launching stations and all of that on earth to help when we launch rockets, but no such infrastructure exists on Mars to help the launch back. Fuel would also be an issue. If the spaceship used up all of its fuel getting to Mars then it's stuck because there's no gas station on Mars to refuel. The amount of fuel required for a rocket is heavy so it's unlikely a ship could carry enough to get to Mars and back. The crash landing would also make it hard. We aren't able to softly land spaceships that are large enough to carry people on planets. Instead, we have to plan to destroy part of the ship in order to protect the other parts. It would be hard to get back to earth with a partially destroyed spaceship.

Aside from accidents and self-neglect, how do you die from dementia or Alzheimer's disease?

Alzheimer's and dementia cause you to forget things by damaging and eroding the brain. You stop remembering things because parts of your brain are literally gone/unusable. Eventually this damage gets to the point that you body stops being able to function and you die.

How does the vacuum in a thermos prevent heat dissipation/loss, but the same does not work for the sun in space?
|
> How does the vacuum in a thermos prevent heat dissipation/loss It doesn't prevent it. It merely slows it down significantly, by eliminating most of the heat lost via conduction and convection, so that the only method left is heat loss through radiation . And radiation is the same mechanism that lets energy from the sun reach us. It's just a **lot** bigger and hotter than the coffee in your thermos.

Can someone explain Stock Options and how they work?
|
/u/flooey does a nice job of explaining the basics, but beyond that there is a lot to understand in how options work. Many people view options as a way to bet on the underlying asset going up or down . Options are not ordinarily the best way to to do that. Instead, options are bets on how much the underlying asset is going to move around they are bets on how volatile the underlying price will be. Here's why: An option's price has 2 parts - intrinsic value and volatility value. The intrinsic value is what the option would be worth if it expired immediately. It is max in the case of a call where S is the underlying price and K is the strike price. The volatility value is what's left after you take that out. So for a call and a put at the same strike price, only one of the two will have intrinsic value. Let's pretend it's the call. Then we have:Call - = Put since the put has the same volatility value, but no intrinsic value. This means that Call - Put = S-K . This is called put-call parity. So why is this important? Well it means that if you exercise an option before expiration, you are throwing away its remaining volatility value. It also means that if you buy the option with the hopes of betting on the underlying going up or down, you're also paying for the volatility value. You would most often be better off borrowing money and using that to buy the stock. Lastly I'll mention that the value of options contract is a function of the volatility of the underlying asset. If volatility goes up, that volatility value increases.

Why do we like to listen to bass? Why is it pleasing when DJ drops the bass?
|
There are 2 questions here. Not everyone likes bass in and of itself; I'd argue that most people don't. Those people driving around with subwoofers are annoying. Low frequency noise makes people feel anxious and can cause nausea and dizziness. It's a noise that's difficult to block. Low bass sounds are associated with danger: earthquakes, large animals running towards us, floods, etc. So we're sort of attuned to notice and dislike low frequency noises. However when it's part of a whole chorus of music, then it's a tension release just like others have mentioned. We can anticipate the bass drop, and we're waiting for it.

If there is a supermassive black hole at the centre of our galaxy, why is the centre so bright?
|
Black holes can be amazingly bright - though not from light escaping from within them, obviously. They are believed to acquire an accretion disc around them rather as a sun does when it's forming. Matter falling into the gravity well will get very hot, with large holes hot enough to shine brightly.

What are the differences between the branches of the US Military?
|
For each branch has particular missions and goals. Each one is also ran differently then the other. And like you mentioned each one is more orientated towards a weapon system. What I would recommend is first decide in a long run what would make you happy in doing and then talk to people in those fields. I have 9.5 years in the Air Force, first 9 as a Crew Cheif on KC-10s and just recently got into a cyber spot because its what I want to do professionally. But I wouldn't trade it for anything. Both jobs and luckily squadrons have been great to me. Hope that helps a little. :) I wish you the best of luck either way

How is GMO bad?
|
It isn't bad for us to consume. It is potentially bad for the environment to farm so few crops. There are also ethical problems with proprietary life. But I wouldn't worry about the safety of eating gmo foods", 'It's not bad for health, it's just bad marketing. * Most people think Youtube video have better authority than scientific papers. Scientists should spend more time making youtube videos instead of writing peer-reviewed papers.* Bad naming, "Genetic modification" sounds scary and unnatural, more friendly name will help. Maybe call it "Organically-Engineered food"?* Use some TV celebrities instead of [Nobel laureates] to promote your cause?', "Since genetic engineering is excluded from organic it's unwanted competition for the organic industry. This is why the organic industry actively demonizes GMOs. Follow the money.

"Time heals all wounds" What exactly is happening here? Why do you feel less "hurt" as time passes?
|
part of it is getting used to the person not being there. but there's also what you with the time since their death. perhaps you have unresolved issues with that person that will take a therapist to help you deal with. problems don't necessarily go away after death.It is not just pain but pleasure that fades with time as well. The phenomenon is called reversion to the mean. No matter what good or bad things happen over time our mental state reverts back to normal.We grow stronger and more resistant to almost everything over time. It's like how a blister becomes a callous. We can do it mentally too. Humans and life in general is very good at improving after taking damage.

Why can't we smell ourselves well?
|
There's a trick. If you tilt your head back and pretend you're shaking a salt shaker in your mouth, your brain will actually simulate the taste in your tongue!!", 'Sensory adaptation. Constant exposure to a smell/sound/etc will reduce your sensation of itIt would be nice if there was some way to get around this, so that I could suggest it to the 8th grade boy I taught last year who really *really* **really** smelled. I could not get within 5 feet of that kid. And he wondered why the girls avoided him ..O_o_URL_0_ Stare at one yellow dot, the others will disappear. When there is some very constant stimulus, the brain will filter it out as background or unimportant.It's because if we are aware of our smell or a bad smell in the environment, we won't be able to detect new potentially dangerous odors, that's why you 'get used to' certain smells.

Why is "father" shortened to "dad", when "mother" is simply shortened to "mom"?
|
It's thought that it may have entered the English language from Welsh, the Welsh word for father being *tad* . Interestingly, the Welsh for mother is *mam*, which is also tantalisingly close to mum, mom or just mam as used in various English dialects.Simply put, English is a creole -- a language that emerges when populations with different languages mix over long periods. Put Celtic, Latin, Danish, German, French and a few others in the Cuisinart, let it run for a couple of thousand years, and you have English. You think "mom" and "dad" are inconsistent? Try "tattoo". It has two meanings in English that came from different cultures and are totally unrelatedBecause if u called your father "fat" instead of dad it probably wouldnt be appreciated by him

Why are buildings in Australia and America not built with sturdier materials, to deal with the regular natural disasters?
|
I'm in Australia, and events such as flooding are so rare that it's not worth the extra cost of building it that way, but most insurances don't cover it, so it's very much a 'cross fingers and hope for the best' situation. Also, almost all suburban houses are brick and mortar anyway, which holds up much better against flooding and fires. Bushfires are a much bigger threat here, but the same rules apply. If you're in the danger zone, get your garden hose ready and hope the firies get it under control in time. And destructive tornados are almost non-existent here.Price. A brick and mortar house is more expensive, and tornadoes and floods don't happen all the time. It doesn't make financial sense for most people to build a home that can withstand something that has a very low likelihood of happening to your home. The "regular" natural disaster is not really that regular. sure, tornadoes will happen in the midwest, but the likelihood of it happening t your particular house is fairly low. Its cheaper to build a safe room to survive the event if it does happen.

with windows XP support ending, will I actually be at any security risk using it, if so, why?
|
first off you pc will get more and more vulnerable as new security holes are discovered or made public . Microsoft will no longer patch your pc for you. microsoft security essentials will still run on your pc if you have it installed prior to the final day of support, after that time you will be unable to install it on xp. It won't however keep you 100% safe, whilst it will be updated to protect against new malware and virus' that affect other version of windows, xp specific security flaws will not be fixed my MSE. You have 3 good options 1) Buy a new laptop, be it windows, mac, chromebook or linux 2) install a free Linux based operating system on your current pc [more info] 3) upgrade to a newer version of windows, though if your hardware is old that may not run well. It's worth noting that the system requirements for windows 8 is lower than windows 7 but windows 7 will be much more what you are used to. I don't recommend sticking with xp.

Why do India and China have such high populations compared to other countries with large land size (like the U.S., Russia, Canada, and Australia)?
|
One major reason why the population size in India particularly is so high is because India is an agriculture based country. It has been since civilization existed in the Indus Valley. Even today 40% of Indians are engaged in agriculture. Now, more children mean more hands on the farm to help out. This means greater amount of people. Now these people have more children who are again born so that they work in farms. If not farms, there are people working in the urban factories as well. Many people have as many children as they can so that the children start working in factories early. Child labour is a big problem here. Source: I'm Indian.

The new "breakthrough" in quantum computing by IBM
|
What do you want to know about? For quantum computing in general, the question is [frequently asked]. If you're asking about something specific IBM has done, do you have a link?", 'Does anyone know what the next step for modern computers are, it seems that quantum computing is a bit too far in the future?', "I'm sure there are much more qualified responses above, but I remember a selection from a documentary quite well that explained this. The way it was explained is first one must understand bits/bytes and binary code. I'm nowhere near an expert on such matters, but look at it this way: each character, number, and so on must be assigned a series of ones and zeroes . There of course is a pattern to it and for this example's sake say 0001 is a, 0010 is A, 0100 is b, etc. Obviously this is a horrible example, but hopefully you get the idea. Quantum computing, as I understand it, is a combination of TRUE/FALSE AND/OR combinations. This is where it gets tricky mocking an explanation to a five year old. Let's say you need to urinate, but also need to eat. There are two different paths right there, but these can branch out further. What do you eat? Do you wash your hands after you pee? Of course you don't, you're five. Just kidding. Anyways, quantum computing would determine all the outcomes, as well as the outcomes that were neigh impossible. Again, for example's sake, let's say what ended up happening is you fell asleep into a coma for not eating or peeing for so long. An extreme encounter, but hell we're talking about quantum computing where crazier has indeed happened. Hope this helps.

My partner gave up smoking the exact second she was pregnant. She started 9 months later, the day she left hospital having given birth.
|
She quit because she had to, not because she wanted to. I stopped smoking because I wanted to, and I looked at smoking as a negative, not a positive. She looked at it as something she was missing out on, and something she didn't want to give up. I stopped smoking well over a year ago and it's the best decision I ever made. Not a single craving, not a single day that I miss it. More info in /r/stopsmoking from others if interested.I quit smoking as soon as I found out I was pregnant, I quit my depression medication and ended up with gestational diabetes so had to give up junk and was very careful about my diet. I was fine because I was so happy and excited for my babies I think it was the hormones made me feel ok without any of those things. Now I'm trying to quit again 2 years later because I want to not because I "have to" hopefully I conquer my addictions for myself this time.

why do my dogs bark at the sound of a doorbell on tv even though we have never had a doorbell?
|
Besides the doorbell, mine come running at the sound of the can opener. They have never been fed wet food opened with a can opener to associate the sound with food yet they all come a running'.If my cats hear other cats on TV screeching or fighting, they start fightingDogs can pick up on certain things like greeting formalities. They possibly heard doorbells several times on TV and the follow up formalities. Expecting a guest after hearing that sound is something known as conditioning. Also, I highly doubt its the "pitch" of the doorbell itself as televisions can only produce a limited range of frequenciesDogs realize very quickly that loud ring= stranger outside. It is the same technique people use to train their dogs with clickers. When a noise is followed by the same action enough times they put the dots togetherMy cat gets nervous from doorbells because she knows strangers are coming. She runs and hides. It was impossible to have Golden Girl marathons without her freaking out. "Hi, it's me Stan!"

Why can't we see lasers from things like laser pointers until they've hit a surface?
|
It isn't just lasers, you can't see the light from ANY source until it reflects off something. If the air is dusty or foggy, you can see that because there was something in the air to reflect the light into your eyes. Air is transparent.The whole point of a laser is to be a beam of light that goes in a straight line and not go all over the place like regular light. If the light is going in a good straight line how is it going to get into your eye for you to see it?', "Lasers aren't invisible to the human eye - as you've pointed out, you can see them. You can't see them when they're passing through air because the air doesn't scatter any of the light in your direction - so there's nothing to see.

Why isn't Canada outrageously wealthy due to their landmass?
|
Land itself doesn't make money, but it is a component in making money. So, Canada has the ability to produce a lot of resources because it has a lot of land, but it is restricted in other ways like capital and labor since you need people to take the resources out of the ground and capital to pay for the machines to do so as well. Also, Canada's resources are in remote areas, adding additional transportation costs. The resource extraction industries are completing against other industries, like heavy manufacturing. Having both industries in your country doesn't mean you have more money in general because both industries are competing in your country for labor and capital. That is why Canada is just at developed nation wealth.

How does the Superman universe explain that Superman looks exactly like a human, despite having come from a planet millions of years away with a completely different environment?

But it makes sense that Jor-El would have chosen a planet for Kal-El on the basis that he would fit in there.

this wonky jet stream giving planes the extra speed from a tailwind. What happens if a 777 breaks the sound barrier?
|
A jet airplane will never break the sound barrier in a jet stream because it will remain at subsonic speeds within the jet stream itself. Let's say the airplane normally travels at 550mph, the speed of sound is 650mph, and the jet stream is moving at 200mph. An aircraft in the jet stream may be flying at 750 mph over the **ground**, but its still only going 550mph through the **air**, less than supersonic. For this reason, supersonic effects pose no danger in jet streams. Perhaps extremely strong streams could have dangerous levels of turbulence, but I'm not sure about that.Breaking the speed of sound means going < the speed of sound > faster than the air around you. Being in the jet stream means that you and the air around you are moving faster.Can I change the question a little bit? Let's say I snapped on some snazzy extra jet engines to a 777 and somehow manage to get it to break the sound barrier. Then what happens? Obviously windows will break and disgruntled old people whose Sunday brunch will call their congressman to complain, but will the aircraft just disintegrate? Would it be able to continue to fly?

Does Schwarzenegger-style body building yield any advantage athletically? Does body building really make you strong?
|
some of them really are that strong. As you can see from the link below, Schwarzenegger competed at some of the highest levels of power lifting in his younger years. I think if he focused on that he probably would have been a champion. I only know the bodybuilders from Arnold's time. Lou Ferrigno actually tried out for a football team as I recall but did not make it. I saw him compete on one of those superstars competitions that they used to show on TV in the 70s. THey did a series of events; he did not do very well. One thing I recall was the long distance run he could not keep up and fell far behind. He later became a New YOrk fireman so he obviously could do athletic stuff. Mike Katz is less well known, but he had previously played football for the Oakland Raiders as I recall. He's the guy in the movie Pumping Iron who is looking for his shorts or something, they had played a joke on him.

Why are so many Americans against gun control?
|
Everyone looking for a logical explanation from these people is missing the fact that their arguments aren't a product of logic, but rationalizations borne out of paranoia and fantasy. I live in one of the most liberal regions of America, and even I have friends who seem desperate to make excuses for why they should be allowed to have guns. Most of them don't even own one. It's a sort of macho paranoid fantasy, that they feel stronger and more confident with access to a gun. The same way people drive big trucks to boost their frail ego. It's fascinating and frustrating to watch. They will employ all sorts of arguments, then invent new ones when their former reasoning is undermined. It's not logic at all, it's emotion.

Why is it safer to turn off the engine/remove keys from the ignition when fueling a car?
|
[Car Talk has a good summary of the reasons]. TL;DR - it's mainly so you don't accidentally drive away or have your car roll away while refueling.Can I just say it is to do with a possible earth fault in the car. When the car is running or the key is turned to ignition current flows in the electrical systems. If you have an earth fault it means that electricity will take the shortest path to earth. Which can be through you or the pump causing fire etc. As earth faults are very uncommon in cars this does not happen often. It is however a possibility. Source mechanical engineer', "Professional mechanic here. I know of precisely one problem with fueling up running cars- On a few specific makes/models, the gas gauge will go all retarded, as the ECM does not expect to see a rising fuel level with the engine running. Usually this results in the gauge never reading full. A 'hard reset' will fix it. There is no other concern. You will not blow up.

Why do toilets reverberate?
|
Reason 1) Forests are very big and bathrooms are very small. Sound is a wave that likes to bounce off of things. When you poop in a bathroom, the bathroom is usually a closed room. The sound of your poop gets trapped in the room and bounces around so more of the sound waves go into your ears. In the forest, the sound waves can just leave. They can go out into the forest or up into the sky. Reason 2) Bathrooms usually hare made of different materials than forests. Depending on your bathroom, it might be home to materials like porcelain, aluminum, steel, tiles , or linoleum. Forests contain mostly dirt, trees, and smaller plants like bushes and grass. Forest materials are much better at absorbing sounds than bathroom materials are. So when you poop in a bathroom, the sound bounces off of the reflective surfaces and into your ears. When you poop in the woods, the sound gets absorbed and doesn't bounce back to your ears as much. Toilets could be made out of a noise dampening material, but it might not work well with poop. Porcelain is good at not letting poop stick to it. Other, quieter materials like plastic or wood aren't as smooth so more poop will stick to them. And a lot of the loudness of pooping is due to the shape of your bathroom and the materials in your bathroom. Try bringing a toilet out to the forest for a poop. It'll be much quieter.

What stops someone from copying my check that they received from me and writing a new one?
|
I worked in check cashing for a while, so I can answer a few questions for you. There are a few things stopping you. 1) Security features on the check. Most checks have several markings that the processor will look for. They aren't terribly hard to fake, but they do trip up some rookies. 2) Instant verification systems. We used a system run by Certegy, that took scans of the check from the register, and compared them to a database of known or suspected fraudulent checks and people. About 2% of checks were rejected by this system. 3) ID requirements. Checks over $50 required a valid government issued photo ID. If the check came back as false 24-48 hours after you gave it to us, we could use the info from your ID to either report you to the bank or cops, or we could send you a demand letter if we had your address. Trust me, you wouldn't just be one of thousands of people to try this very same trick.

Why can we "develop a taste" for things we originally dislike, such as beer or certain foods?
|
Some good comments here, especially about the brain adapting to 'like' highly nutritious foods in times of need that it would otherwise find repulsive. I think that in every day life though that it has a lot to do with two things: operant conditioning and social learning. So take beer: beer is gross. It's bitter and has a nasty aftertaste. However, I love beer. Why is this? Well, I'm sure everyone would agree that your first beer definitely isn't your most enjoyed beer. However, you begin to associate that taste with the feeling of getting drunk, as well as having good times with friends. Eventually your brain learns that the taste of beer means a good time, so you start to enjoy it. Same with foods: kids are born with an innate preference for sweet foods. The rest, veggies and such, they get a taste for by watching others eat them and enjoy them. Similarly, if they eat something and then later throw up then they'll most likely grow up disliking that particular food. Hope that helps.

Why aren't MLB ballpark dimensions standardized?
|
Originally a home run was a ball that was hit so far away that it couldn't be recovered and brought back into play quickly. It wasn't a common element of the game when it started, so the idea of it being somewhere beyond the first obstruction was vague enough. As ballparks came to be built, they erected fences to exclude people from the field, and to make sure players didn't wander into traffic when chasing a fly ball. It was site specific. All games have elements of unique venues, indoor, outdoor, real turf or synthetic. It's weird for a distance to be non-standard, but that's just how baseball started and no one has bothered to change it.

Why is the U.S. against high taxes and more social programs if this model seems to work so well elsewhere in the world? (e.g in Canada and in many European countries)

Well not everything work in Canada and Europe.

Economics is complex and that's why so many people disagree.Because America was literally founded on distrust of government. Also, everything the government touches just gets worse.

Why North Korea broke the ceasefire with South Korea and the effect this will have on the US
|
A lot of these answers are aimed for people way beyond five year olds, so here's my shot at a 5-year old level answer: So sport, think of it this way. Let's pretend that you are South Korea. I know, it's a bit hard to pretend you're a country, but just try to imagine that. The bully on the playground who you don't like? That's North Korea. I know he beats you up sometimes, but then your teacher comes and tells him to stop, and he does for a bit. Now that bully learned this kind of behavior from his dad, who probably learned it from reading a book called The Prince by Machiavelli. Don't worry about that book till you're older though. The bully just wants to be like his dad, the same way you said you want to grow up to be just like me. His dad did this kind of stuff a lot before, so now he's trying to be like his pop. The teacher might come in and stop him from beating you up, but he probably won't do that unless the bully starts getting really violent for a long time.

This is just my opinion, but it seems evolution gave us nails as tools to use but like teeth there needs to be sensitive nerves underneath to tell if the enamel is touching something. So the sensitive nerves are a by-product of the tool. Nails and teeth aren't there just to protect nerves.

why am I exhausted after a long road trip?
|
When you are in a car, your body must absorb all of the tiny bumps that the car's tires and suspension cannot absorb. This tires out your body as your muscles are essentially acting as suspension. It is the same when you travel by train. if you are more interested in material fatigue) You are also mentally exhausted, as oddSpace correctly mentioned.

Why does a person become angry/moody when they're tired?

Guys stop saying 'Dopamine increases or decreases' because it means shit. That's waaay to reductionistic for the complexity of the brain.For anyone interested, here is a link to a 2 hour interview with a top neuroscientist on just about every function of sleep. He has written a very interesting book on the subject which is linked in the video description. _URL_0_

Why hasn't anyone actually attempted assassinations of the North Korean leadership?
|
[In 2012 there was an attempt], it just failed. Long Version: Rumor has it this was backed by China. [Kim Jong-nam], Un's older brother is probably currently being backed by China in case of a NK collapse. Neither China, South Korea, Japan, or the USA want the the regime to collapse as this would make a 23 million person humanitarian crisis that no one wants to deal with or fund. The better route is to let China continue to take stabs at the leadership every 5 years and slowly bring them in to market economy, which is exactly what we have now. However, if they do fuck up badly enough, we will drop the Almighty Hammer of God on them anyway.

Why are Masters and Doctoral students called "candidates"? It makes it sound that there is a chance they won't earn the degree
|
Because there is a chance they won't earn their degree, particularly the doctoral students. Masters degrees sometimes and doctorates almost always require a thesis, which represents some new contribution to the field. You have to present your thesis to a committee and defend it. If they don't judge it worthy, they will reject it, often pointing out the ways it is deficient and giving pointers on how to correct them. However, sometimes the research is flawed beyond repair or the student proves unable to remedy the thesis. That candidate would have to basically start over on a new area of research if they were even allowed to continue at the school. Many masters degrees these days no longer have a thesis requirement, or it is optional and be substituted with additional class work. In that case, candidate is merely traditional. Bachelors degrees never had a thesis requirement, so bachelors students were never candidates.In my PhD program, about a third of the candidates didn't complete their degree. Almost all of those used the work they had completed to earn a "terminal master's degree" and went on to a variety of interesting careers: teaching, the corporate world, journalism, non-profit organizations, etc. When you think about it, this isn't unusual: some undergrads don't complete a degree either , so they're "candidates" in the same way. But I suspect colleges use the word "candidates" for PhD hopefuls because in their last few years, they're mostly doing independent study and writing rather than taking classes, so they're not entirely "students".

What would happen to a naked human body in space with only a hermetically sealed and pressurised mask and underwear?
|
Since you have a pressurized mask on, you have pressurized air in your lungs too. Since there is a vacuum around your body and the mask is sealed against your face the pressure ruptures your lungs and you die. It depends on the type of underwear though, boxer briefs and you'd probably make it out ok.
