What exactly has President Obama done to make people hate him?
I don't hate him. I hate what has happened while he was chief executive. On his watch the market has crashed. Confidence is down world wide in our country and economy. Everyone I know is broke or in foreclosure or underemployed. Sure 2005 was great there were tons of construction companies and people making money like crazy. The looked for somewhere to shield their money from taxes and real estate went nuts. Hope and Change was supposed to be better than the Bush Era and it's not. Things are worse and getting worse. The 'new normal' is pretty shitty imho", 'Too much time spent trying to be bipartisan when he had the chance to push through on the most important policies voters had elected him for - this gave the numerous extremist conservative folks more of a voice with voters. Too late a transition to a "harder" line when congress turned more to a republican majorityBecause unfortunately, many, many people in this country, including grown ups, are what experts call "low information voters." That's a nice way of saying "not very smart, and not very well educated." And it's even more sad that most of these people have no interest in becoming educated. Also, racism.
How do we know we are in a spiral shaped galaxy?
We know that there's three different kind of galaxies - elliptic, spiral and irregular. Simply because from thousands of different observable galaxies all belong to one of this classes. And from here it's easy to check in what kind of galaxy we live.Our galaxy is flat - you can see it with any telescope. So it can't be elliptical or irregular.
Why is the skin on our arms and legs generally clear and beautiful, while our faces and back tend to get acne and clogged pores?
Okay so this is what my dermatologist told me. The skin on your face is more sensitive and thinner than the skin on your arms or legs. It's more prone to damage or redness. Your face produces a lot of oil. This depends on many factors. Could be because of increased cleansing , genetics, hormones, environment and a whole host of other factors. The skin on your arms and legs is a lot tougher than the skin on your face. It does have oil glands but not to the degree that your face does. Increased oil production leads to higher chance of acne. Simple as that :)
Why is it so common for famous people to have been married multiple times?
I'm pretty sure this hasn't been explicitly said, but the people you're thinking of have usually gotten to their fame because of an extreme commitment to their careers. The most popular actors and musicians at any given moment probably work 70-90 hours a week to get and stay at the top of the pack. That doesn't leave a lot of time for relationships.
Why does the Forbes rich list exclude certain billionaires?
because it would be problematic to see who actually owns the world and why the world is trillions of dollars in debt you wouldn't want to be a nazi would you? good, now pay your debts created from artificial inflation created from currency not regulated by your government or people :^)", 'forbes is a news outlet with reporters. it's all guesses and people like gates, slim and buffet are extremely high profile public figures which makes it "easy" to estimate. Gadhaffi was reportedly worth $200 billion. So I can only imagine there must be a trillionaire out there that has billions spread out across the globeAhhh the Rothchilds. Careful which questions you ask there is a certain class of wealth that despises being in the media. So much so that id guess they pay to be excluded. Kinda like a dont call list. But a dont print list.It probably has something to do with when you are a billionaire you can make most anything you want happen, and if you don't wanna be in a magazine you just kinda make it so you're not.
Why isn’t every bone in our body made to be as strong as our femur?
Because they all have different functions, some of which require thinner or smaller sizes, necessitating a different overall strength for the bones. Any material, be it bone, metal, or paper, is going to be easier to bend or break depending on it's shape and size. The tiny bones in the inner ear help with hearing, and are required to be easily vibrated, having them big and thick and strong would not be advantageous.Besides everything already mentioned, weight. The femur *needs* to be that strong because it carries the entire weight of the torso, arms, head, etc, while also providing a place for large muscles to attach/pull— muscles that lift all that weight. If the ribcage, arms, etc were equally big the femur would need to be bigger as a result. Otherwise, it would break more often not only because it carries more weight, but nothing else gives way first if the body’s subjected to bone-breaking levels of force', "Cost. Building strong body parts isn't cheap, and energy/materials in the form of food isn't infinite. In eons past there were mutations that favored building muscle and bone and everything else, but they didn't reproduce as prolifically and successfully as the ones that prioritized brain development. Needlessly strong bones beyond what's needed to find food, procreate, and put up with reasonable stress that's a waste of precious resources.
What makes us get a 'Stitch' in our sides when we run too quickly?
I have no idea what causes it, but our high school track coach theorized it was because too much in the saliva you were swallowing while you ran He said to cure it, just keep spitting as you run - which i did, and seemed to work - not sure if it was coincidental, but it did seem to work for me..
How does Flint, MI still not have clean water?
You can't fix a city's entire water supply infrastructure over night. The system is underground, so even the parts that can be dug up are under streets and people's yards. Then there's the parts that run under buildings and such . Not to mention, it's been winter up there. The ground is frozen in winter, which adds that much more labor to the whole process.
Why do people consider male circumcision horrible?
In fairness, you can't really say it is easier, as you can't compare before and after. That choice was taken away from you without your consent.
when I'm really depressed, what causes the physical feeling in my chest that feels like a sad heart?
When you are aware of that feeling, half of the work is already done! you now need to learn to observe this feeling objectively and note it's characteristics. The more you note it in a balanced way, the more you're getting rid of your depression. This is a way taught in vipassana to overcome all unsatisfactoriness. good luck!
Why is Hitchhiking illegal?
My post was removed by the mods because it wasnt in-depth enough. I'm not sure how much more in-depth I need to be with this answer but it is illegal to walk on major highways in Canada. That is why it is illegal to hitchhike. It's for the safety of the person walking down the highway rather and for cars that stop alongside the road to get people.
the 101 on guitar pickups
All the explanations on this post are good, but I feel like you might be looking for an explanation that is less in depth, so here ya go. Single coil pickups look like they are about the width of your finger, a fender stratocaster is an example of a guitar with single coil pickups. A humbucker looks about twice as thick as a single coil pickup and often sound a bit more full and meaty. A Gibson les Paul is a good example of a guitar with humbuckers. Both types can be either passive or active, the ladder being less common. Active pickups require a battery and tend to have a hotter signal than a passive pickup. Hope this helps, and sorry I'm not the best at explaining things like this, but this should give you a rough sense of pickups. The more you play and listen to different things, the more you will just naturally start picking up these things. Pun intended.
Since oil is 1/3 the price is what was 2 years ago, how come gasoline isn't 1/3 the price?
No one's mentioned that the cost of Ethanol which the government mandates makes up 2-10% of your fuel depending on the state, which has a price of 5 dollars a gallon.
When we say things like "2/3 of all ocean life remains undiscovered," how do we know what we haven't discovered?
I am working on my bachelor thesis as a marine biologist right now. Our team has taken samples from the bottom of the sea near the Kurill trench . Everytime the hyperbenthic sledge comes up, 90% of the animals are new or at least new species. I am currently describing a specie that we don't even know what it does or how it actually lives..
If automation ultimately replaces a majority of the workforce, then where will the demand for those goods which are auto-produced come from? Wouldn't automation ensure it's own obsolescence?
Full automation's ramifications are hard to project, which is why people like arguing about it so much. That said, in a late/post-capitalist society it can be conjectured that the economy would rebalance in such a way as to allow the free flow of goods to the largest possible number of consumers. Exactly how the macroeconomy would shift would determine effects on demand. Speaking realistically, I don't see consumerism going away, even if we make it to crystal spires utopia where nobody has to work thanks to tech. People will always like consuming, producing, and sharing. People will go right on wanting things, and others will accommodate that desire, whether through their own labor, or the unlimited labor afforded by full automation. We don't assign value based solely upon the amount of human labor that went into it. We judge a good or service by its intrinsic and assumed values, which aren't diminished to nothing by removing human labor from the inputs.
When you take that little square tag off a recordable VHS tape, it makes it non-recordable.
The VCR is simply checking for whether the tab is present. There's a switch positioned so that it's pressed by the tab, and the VCR will only allow you to record if that switch is pressed.we used to get videos that were sold as films from rent shops or bargain bins then use a bit of sellotape to put over where the hole is and it lets you record to a vhs tape and was cheaper than buying "recordable" VHS ..this was back early 90's of courseBut, if you stick a bit of tape over it, it will record again. This holds true for audio cassettes, and micro-cassettes as well.
Why Do More People Blame Illegal Immigrants for "Stealing" Jobs Than Business' for Hiring Illegal Immigrants?
People are insecure about the economic realities: Illegal immigrants will do more for less. It's like businesses upset at Walmart for stealing their customers by offering lower prices.
Why do school buses have no seat belts?
I was in a bus collision 9th grade. It felt like the driver didn't realize there was a speed bump; We all jumped a bit, but didn't think anything of it. The bus stopped. We look out the left Windows. There laid a car, looking as though it had been mauled by a meat grinder. The only damage the bus sustained was a chipped window.I think the lady in the passenger seat of the car ended up becoming a paraplegic. Sad.There are a lot of factors which make bus travel safe. One is the fact the bus has a high momentum and seeing as momentum is conserved, it will deccelerate less in the event of a collision. The bus passangers will be rather safe, the passengers of the vehicle collided with the bus not so muchEvery school bus I have ever been on has seatbelts, we just were not required to wear them. ', "Long Island teacher here; our district owns 2 mini buses and contracts out to a larger company for typical large buses .about 15 of them. They all have seat belts. We make the students wear them for field trips but they aren't enforced on their ride to/from school, but may kids actually wear them. I was surprised to see how many buses don't have them according to this post.
If the human body completely regenerates it's cells after five years, how are tattoos so permanent?
The ink is placed neither too low nor too high in the skin's layers. In the dermis is believe.
What exactly do finance departments at large companies do?
On the topic of integrity, think about bribes. How can a finance department detect and determine inappropriate use of funds? I'm not going to do your homework, but you can search about cases or corporate bribes and how they were finally discovered. Maybe somewhere you will see a case of that new finance guy seeing 30k going to the same place every quarter with no explanation
Why do porns always look amazing at first and ridiculously disgusting once you have masturbated?
First and foremost, after watching porn, it doesn't disgust you, but *you* are disgusted by *yourself*. It's simply the matter of shame and the feeling of emptiness. When I rub one out, I feel great. I actually feel relieved and over-all completely satisfied with myself. You need to acknowledge the fact that it's a natural thing to do, and have some self-respect.
Why is it not a criminal offense for a bank to evict the wrong house?
Now I'm wondering if it's legal to defend against a wrongful, forceful eviction like this in the states.
How games are converted to run on Linux
It isn't hard when game is written with portability in mind. Say, developer might use SDL and just compile his game both for Linux and for Windows. It will just work! However, developers often write games having only Windows in mind. Then there is a lot of Windows-specific things in their code, and changing them all just takes a lot of time. Some parts need to be completely rewritten.
Why isn't cancer easily curable?
It's because cancerous cells are your own cells! Your immune system can't distinguish them from regular healthy cells. Let's imagine you have a robot guarding your massive ranch in the Yukon. You give the robot specific instructions, shoot anything that isn't human. Over the years it kills bears, wolves, foxes, wolverines and anything nasty that's trying to get into your home. One day, a couple of men with guns show up. The robot lets them through, because they're people.
Why is American culture so obsessed with youth and views getting old as a horrible thing?
America is a country based in innovation, migration, all kinds of change. Young people are good at that. Old people tend to settle down into a proven way of doing and thinking. That's valuable too, but it's not the reason for America's success.I dont think its solely an american thing, look at Asia. They are obsessed with looking like children. There are entire subcultures where adults do whatever they can to literally look like a childYoung people look better feel better perform better every thing is better when you are young. Except you lack the experience to really leverage any of that to its maximum. Youth is wasted on the young, or something like that.
Why gun prohibition worked in Australia but wouldn't work in the US?
Maybe someone else mentioned this but organized crime is responsible for a significant portion of gun-related crime be it homicide or armed robbery etc. in America. Making guns illegal, or further regulating their sale and use would do very little, if anything at all, to address this. The root cause of most gang activity is the presence of a black market in which money can be made, so legalizing drugs and prostitution would be a better fix to that problem. I don't know anything about organized crime in Australia, but I imagine their gang-problem wasn't as big as America's.
Zeno's Paradox (infinite halves)
step 1) Walk half way to the kitchen step 2) Call this your new starting point. step 3) add 1 to your step counter step 4) goto step 1. Zeno's paradox is that you have to complete and infinite number of things, which is impossible.Zeno was a moran who didn't understand limits. Either that or he was trolling. The size of the steps decreases at the exact same rate that the number of steps increases. These two factors exactly cancel each other out. And real motion is therefore possible. But you didn't need the mathematical explanation to tell you that. We all know Zeno is wrong because we all know that we actually can walk, and it actually does work. Zeno's "Paradox" is actually Zeno's Fallacy. An interesting idea that's completely wrong.
How does Costco afford their high minimum wage?
The subscription fees are essentially free money since they don't pay for anything they can use it to pay wages and someone decided to knife the competition and put it towards their most important customer:their employees", 'The wages also help to promote their place in the community, so more people will feel better about shopping there . Walmart runs OK for a few years, but the backlash comes from the fact that many of their employees are on government assistance. The people that work there are part of the community, and while not rich, can at least afford to live a middle class life there.Something i haven't seen mentioned is retention. Many Costco stay for a long time, which lowers saves money because resources don't have to be used constantly training new employees. Also the longer an employee remains the greater their domain knowledge, which boosts productivity, and this justifies the higher wage. On the other hand the minimum wage positions at Walmart have a lot of attrition which requires constant training and yields employees with little knowledge and bad productivity.
Why don't American's have citizenship to their ethnic origin but offspring born abroad have American citizenship?
Typically, countries only allow citizenship to pass on to children born abroad for one or two generations. If Joe's family stays in Ireland and his child never lives in the US, then Joe's grandchild won't be an American citizen.
What is that old people smell?
I know exactly what your talking about, it's the smell when you sprout mung beans on a damp paper towel in your desk drawer. Very nutritious but they smell like death
Depression sufferers - How do you explain to someone without depression what it feels like to have 'one of those days'?
My explanation is also my brake system from going too deep into the downward spiral I'm in a deep ocean without my life vest, far from land. My life vest? Hope. Without it I'm sunk. So I keep the analogy in mind and search for hope like I would a rescue ship. Sometimes, even flotsam has to do. Keep afloat, friend.
why do only men have adams apples?
Both sexes have them, it's just that testosterone creates additional cartilage in that area to protect the vocal cords and deepen the voice.
Explain to me like I'm five... "cloud computing"?
I'd argue that its more that just 'stuff on the internets'. ITs 3 things that haven't been mentioned: 1) Elasticity - the amount of computing power/storage/other resources you use can grow *AND* shrink over time. Quickly, and easily. With that, your costs change the same way. 2) Automated - cloud computing is highly automated. The elastic nature described above can be easily and quickly automated. 3) Self service - users / application owners can deploy their own stuff at will, without needing IT to do the work for them.
Why does a camera flash flash, instead of just keeping on a steady light until the picture is taken?
The reason it is still continued today when we have such access to electricity is because flashes of light also stop motion. So, when it's dark out and the shutter speed is invariably open longer, a flash of light will make the image look crisp, still, and, in focus as opposed to simply bright and blurry. This is why studio modeling lights also have a flash of light when the photo is captured.blinding light, battery consumption . Its probably just those things mostly. studio's will have constant lighting to set the shot up, but even those will "flash" up a notch for the photo usually.
How can 1 or 2 locomotive(s) push/pull soo much tonnage
It takes a lot of effort to get a train like that moving. But, once it gets going, there isn't much friction slowing it down.
Why is prom such a big deal in the US?
Mostly because American media makes a big deal about it. Art inspires life. Also because a fairly significant amount of kids will go off and have sex afterwards. But lots of kids don't even go.
Why do I occasionally (in a wakeful state) feel as if I am in a dream-like state, as if everything is surreal (and feel like I'm floating)?
i get this from time to time.. but it actually feels very nice. everything is slooow, and you kinda know what your next movement is gonna be, but somehow it's still unpredictable due to the sensation.. this reads like crap. it's like being super high, but you're not really high.. maybe you're getting too little oxygen into your brain while that happens.. i dont know what causes it for me", 'This is incredible. I, too, experienced this as a kid, especially when jet-lagged. I could barely describe it to my parents, but I remember saying "I feel like I'm dreaming right now" but I probably sounded crazy as hell. I so rarely visit the ELI5 sub, and to see this today man. I'm so glad to learn there was an actual explanation for that feelingWe might just be talking about sleep inertia here.
Why are there so many IT workers on reddit?
Historically, and this is even before the digg exodus, reddit was a site that catered to nerds/IT. It's also obviously largely run by people with IT backgrounds. It's over time that its become a more mainstream site. IT/Nerds tend to like reddit because their job gives them a lot of time to slack off but they're on call so they can't commit to say playing an entire game of something. Reddit is the perfect slacking solution.All IT workers use reddit because anyone who knows anything about computers uses reddit. IT workers are always around computers. IT workers spend a lot of time waiting for things. Source: I am an IT worker.
why does everyone use q-tips to clean ear wax when the box specifically tells you not to? Where did that start from? And what should be used instead?
I discovered the cap from a Bic pen works great to scrape the insides of your ear canals. Removes wax and also feels wonderful. Unfortunately the pointy part also works great to puncture your eardrum. That doesn't feel so great. :( I've decided Q-tips are the lesser of two evils.I never used Q-Tips because we always had a wooden ear-cleaning tool. You can definitely find them in asian supermarkets and they look like this: _URL_3_My mum always used one when I was little so I grew up using those instead of Q-TipsThose labels are just to keep away from law suits if someone does damage their ear drum from using q-tips. Its like alcohol adds that say drink responsibly.
Why is square dancing a part of the PE curriculum in so many states?
That's brought back a childhood nightmare for me, we were made to do Morris Dancing _URL_2_ by Mrs Ashton back at Junior School. If you haven't seen it, it's pretty much the inspiration behind the Fish Slapping Dance _URL_2_ . Teachers are weird.
Why, in America, if someone hurts themselves on my property, and it was their fault, do I have to pay for it?
It's an **old** tradition that guests of your home are your responsibility. Like biblically old. With that duty comes the right to have control over their actions on your property. Modern law is interpreted from this. Why is there a case for this at all? Because your insurance can pay for it. had you not had insurance, I'm pretty sure that you would have never been sued.
Why is the age to drive a several-ton vehicle 16 in the USA, but the age to operate some simple machinery such as garbage compactors and cardboard balers 18?
Actually the minimum age to for a commercial driver's license is the age of 18, and to drive inter-state is 21.
The UAE wants an artificial mountain to increase rainfall
This mountain really only has to be a good size hill. I'm surprised that they don't just move there landfill to the mountian location and start pling trash, we have mountains of trash around here. this is cut and paste from another reddit comment. 2) The feasibility of building a sufficiently large mountain. Yeah. Not so sure about this part. To affect local precipitation patterns the mountain/hill would probably have to be at least 100-200 ft high but also perhaps a mile wide. Again, UCAR is apparently studying the configuration and that'll play a role in whether or not Dubai goes forward with the plan. _URL_0_", 'You mean Nepali, Indian, Sri Lankan workers will build it for them while working in 50 Celsius heat and constantly worrying about whether or not they will be paid last three months wages, then going back to the labour camp that will make you weep if you saw itAre deserts important to the planet or would things be essentially the same if not better without them?', "Would it not be easier to practice cloud seeding with at least a modicum of success? To build an actual mountain that would be large enough to effect the weather seems incredibly wasteful and could look awful if it doesn't look natural. I'm just picturing a massive wall much like a dam Edit: didn't realize there weren't clouds at all :x
Why is finding "patient zero" in an epidemic so important?
One more important thing to note is that the disease samples of P-Zero are likely to be the original mutagen. Considering how diseases adapt themselves according to the host or environs they find themselves in, it is important to know what the original structure of of microbe looked like. That way it is possible to simulate the possible mutations and find a base counter to all of them. If that isn't possible, then one needs to try out different vaccine strains which cost a lot of time and money.
Why does sunlight reveal a ton of dust while artificial light doesn't?
Can you see dust very easily when you are outside? Not really, at least not any better than when you're inside, it's just brighter outside. I think what you're talking about are sun beams coming in through a window and lighting dust in the air inside your room. The reason this illuminates the dust very well is because the light is more collimated and direct. When you light a lamp in a room it is reflecting and diffusing the light off the walls and ceiling so the light comes from many directions at once and it's more spread out. The dust is there, it's just the same brightness as the rest of the room. When you have a beam of light though like a laser, a strong flashlight, or rays of sunshine coming in through your window as the sun sets, the light is focused and directional so when it strikes the bits of dust in the air it's reflected and much brighter than the rest of the room so it shows up very clear. When you measure the air quality for the amount of dust, it does so in a similar fashion, by shining a light onto a photo receptor. The light is a known brightness and the receptor responds with a known voltage. As the amount of dust in the air increases, the scattering of the light causes the voltage to drop on the photo receptor and by carefully measuring these slight voltage drops, you can make an estimate of the PPM of dust in the air. There are more accurate ways to measure dust like using two charged plates instead of a light and photo receptor but in principal it can be done.
Why do cats always seem to want to lie on whatever I'm working on, or to crawl into tight spaces?
Attention. Attention. Attention. If they want lovings they'll do whatever they can to get you to just simply acknowledge them. Just a few minutes ago one of mine did his routine of paw the monitor because he knows I'll yell at him. Then he'll turn around and be cuddly, because I acknowledged him. He's a shit head.
if someone has massive credt card debt and that person dies, what happens to the debt?
When a person dies, everything they own and everything they owe goes into an estate. The estate pays the debts and if there is leftover then someone could inherent. However, if the debts exceed the assets then all assets are sold to pay the debts and any remaining debt simply dies. Collection companies don't like this very much and will often attempt to convince dead people's family to pay. The legalities of that are questionable but they do it because some families don't know better and will pay the debt.
How can someone be tried and convicted of resisting arrest, but no other crime?
You can be lawfully arrested even if you have not committed a crime. For example, if you happen to be jogging at night in black sweats and a ski mask when a burglary occurs, a police officer would have probably cause to arrest you. Resisting that arrest is a crime in and of itself. It is important to remember when interacting with law enforcement that both you and the officer might not know the whole story. The officer doesn't know you are innocent, and you don't know how guilty you appear. Believing you are innocent does not grant you the right to resist arrest.
Why aren't air conditioners liquid-cooled?
Because liquid water is incompressible with readily available equipment. It's not more efficient, water has a higher heat capacity than air, but it's much easier to heat and cool a gas than a liquid. What counts here is the properties of the refrigerant when compressed versus when decompressed. Compressed refrigerant will shed heat into air, but decompressed it will rob heat from air. No matter the other qualities if it doesn't do that, it's not a usable compressor refrigerant.
Why isn't there a streaming service like Netflix for video games yet?
Do you mean, like a service where you get access to a huge library of games for a subscription fee? Or do you mean a service where you stream a game's video to, say, your cellphone? If it's the second, there are companies trying to do that. The nVidia Shield is a handheld that lets you stream PC games from your computer, so you could like play in a different room, I guess. They're working on figuring out how to do it with servers so that you can play anywhere.
How does it take 660 gallons of water to produce 1/3lb hamburger?
It's misleading. It's not like all that water would have been put into municipal water supplies if the cow hadn't drank it. So yes, they require a lot of water, but luckily that stuff sorta falls from the sky. And yes, I knew it doesn't fall from the sky in California. But not all the beef is raised there. Some of it is broughtnin from other states.
If a human head is separated from the rest of its body, is there a way to keep the head alive, medically ? Will the person still behave normally ?
Don't listen to these nay sayers. The answer is yes to both your questions, but the technology required is beyond the scope of our current abilities by a very very long way.
If electricity takes the path of least resistance, then why do lightning bolts always look like a squiggly line instead of a straight one?
In think you've answered the question in part, in your question. The path of least resistance does not necessarily mean a straight line. Environmental conditions - electrically - are never homogenous, but rather ever changing as you change altitude, and location. So the path you see really is the least resistive path.the resistance of gasses can change wildly with everything from pressure to temperature. in open air those pockets of lower resistance are basically completely random, but can be so large that going 3 times as far is still easier.
why there are more diagnosis' of Autism in north america than europe, asia, etc.
It could be because of how school is structured; like ADD. ADD is easy to diagnose if kids are to sit on their ass and learn a limited amount of subjects for extended periods of time. But for some reason, ADD symptoms don't really present in PE and active Electives like history class . In the US, we prioritize structure and compliance.
How does this shooting in California not prove that stricter gun laws won't help our problem?
Weapons can be available in other states, and there's no simple mechanism to prevent them from crossing borders. You can pretty freely move state to state. Additionally, many gun laws have goals other than simply outlawing a specific weapon in a specific region, such as more thorough checks, waiting periods, and so on, which simply aren't at all addressed by your proposal. Not that I'm saying this proves they *would* help. Just that this does not prove they won't.Even if all the guns from all the people who acquired them legally and are responsible gun owners were taken away and it was an extremely comprehensive and expensive process to legally purchase a gun, criminals would still have them. There are far too many in circulation to curb that. "Good people don't need laws to tell them to act responsibly and bad people will find a way around the laws." - attributed to PlatoThe weapons used in the assault were acquired legally. That is the basic issue, that gun laws vary wildly by state and even county.
Why retail video games are still sold as CDs rather than as USBs for PC gaming?
USB storage still isn't cheaper than optical discs. You can buy blank DVDs for under 20 cents each, retail. 4GB flash drives are cheap, but they're not that cheap.
Why do we make the "ahhhh" sound after drinking something refreshing?
Probably a learned social phenomena. Similarly, most people when sneezing make the achew sound, but deaf people dont because they've never heard it before.
Why is it so difficult for people to change their perspective on something when the evidence clearly shows that they are wrong?
It's been called the backfire effect - contrary evidence doesn't change the opinion, but rather entrenches it. It's a form of [confirmation bias].
Why do I "Cringe" when I remember something stupid I did?
Because you're embarassed at what your former self did, that your current self does not approve of.Thanks, now I remembered something stupid I did.
how and why is eating meat so bad for the environment?
Mostly eating meat is inefficient. Instead of eating a plant, your are eating an animal that eats a plant, one that spends a few years turning plants into poop until you are ready to eat it. That's a lot of additional resources, compared to just eating a plant directly.
If women workers are getting lower pay for equal work, how come companies don't hire mostly or all women to increase profits and therefore, out-compete rivals?
There are a lot of people who are claiming there's no wage gap as an answer to your question. This is obviously bullshit if you think about it; it implies that not only is there no wage gap, there could never have been one, even back in the days of overt sexism. After all, it didn't make better economic sense back then, right? There are actually two real reasons: first, employers who pay women less aren't being consciously malicious. They unconsciously believe that women are less competent. ) What this means is that a company can't really consciously decide to pay women equally. As far as they can tell, they already were, even if they factually weren't. The second reason is that relatively little of the wage gap is actually direct pay discrimination at all. Even if you personally really were paying women perfectly equally for a given position, you still live in an economy where women are directed towards lower paying fields, and encouraged more than men to take time off when they have kids. This all means that completely beating the wage gap is already impossible by the time they're applying for jobs with you. Since you can't just consciously decide to pay women equally, you can't get a competitive advantage for paying women equally.
Why do some materials become brittle when they get cold and others do not?
I've read through comments and hope you don't mind one more follow up. Imagine a very long perfect rod of glass. One end you heat until it's close to melting. The other end you cool gradually with liquid nitrogen. Could you please describe what the continuum is between one end of the glass and the others in terms of shattering and melting? Is it simply heat affecting molecular movement? Is there a point we could find on the glass that would have an exactly 50/50 chance of shattering vs denting or bending? Are there materials that are NOT like this? Thanks if u have time to answer ", 'Molecules arrange themselves differently at different temperatures. Imagine the molecules are the monkeys in ‘a barrel of monkeys . When it’s cold the monkeys arms curve less and it is easier to break monkeys apart. When it is hot, the arms get larger and curve more, making it harder to separate monkeys from the next one. Some monkeys are not as affected by temperature as other molecules. 🙉Actually all materials do. Just not at the SAME temperaturesSome materials have to get a lot colder before the difference is enough to notice it
Why is 100°F air extremely hot and uncomfortable for humans, while 100°F water is slightly warm and pleasant?
100 °F water isn't too pleasant if you're immersed in it for a long time. When you take a shower it is warm and pleasant because you don't overheat. A hot tub is nice and cozy because it warms you up. A very weak 100 °F sauna is also nice and pleasant at first. Edit: [this article] is a great source. It mentions that air is thermoneutral only up to ~28 degrees , while water is thermoneutral to 35.5 degrees. So 38 degree water would only be slightly above the limit while 38 degree air would be significantly above it.Sit in 100 degree water for an hour and then compare the experience to standing in 100 degree air for an hour.Whether 100°F air is comfortable or not depends a lot on other circumstances. I've discovered you can be quite comfortable at that temperature as long as the humidity is very low--think desert-like; you are well hydrated--maybe drinking a cool drink; you are not doing any physical work; you are sitting in the shade; there is a light breeze; you are dressed in light, loose clothing. I experienced this in the eastern part of Washington state, east of the Cascades, where the humidity is typically very low in summer.
Why is it that all planet's are relatively spherical?
Things always want to spookily stick together in space. If your ball has a bump on it, then it will be pulled by the rest of the ball to stick all over it. But if your ball isn't large/strong enough, it can't pull the bump down and make it a ball. Then the ball and bump remain together. --- I tried to ELI5.Generally because gravity works evenly on everything around a single point. When a planet is forming out of debris or gasses or whatever, as the force of gravity increases with the mass, it will be acting on everything around it in a spherical shape.
why haven't we been able to land on Mars?
We've landed a rover on Mars. If you're talking about human beings, that's a different story. First, there's little funding for that type of endeavor and it would cost quite a bit. Second, there's the issue of whether humans would suffer too much from radiation and the lengthy zero-g mission. It's also a technical marvel to be able to send humans to Mars, land, perform a mission, then take back off and reach Earth safely. I'm sure it'll be done at some point, but it's a matter of will to do it and the will just isn't there right now.
Why did Google succeed and AOL crumble?
AOL was an online service provider around the time the WWW was becoming popular. At the time, the Internet as we know it today isn't what was widely available; AOL, Compuserve, some other big players and small dial-up BBS communities were what you got, and aside from BBSes you typically used the provider's installed program to access their services, not a web browser or email client like we use today. Their business model needed to keep people paying for their service and using their proprietary software, but with Mosaic, Netscape, Gopher and other vendor-independent browsers it quickly became cheaper and more interesting to use a simple bare Internet service provider and the rapidly evolving WWW. AOL tried to add Internet services to their product but couldn't keep up with the pace, offerings or pricing but were popular for a while on the Internet with Webcrawler, the first Internet search engine I recall using and AOL Instant Messaging which still persists today. Google is only recently becoming an Internet service provider. Their first thing was the search engine. They were the first I know of and the most effective at providing useful search results while keeping spam links to a minimum. Plus they were free, so everyone came to use them. They smartly played off their popularity to sell ads that are less annoying than other providers' ads , offered unprecedented amounts of free email storage and free spam filtering for their gmail service and gradually introduced other products that people want. They make their money off of advertising to their users, and they have effectively attracted users to their free products. So AOL started proprietary and couldn't keep their service competitive with Internet + world. Google made using the Internet more usable for free as long as they get to spy on what you're doing and show you some of the least annoying ads on the Internet.
The colour and birth of wizards (LOTR)
I thought that while the white wizard was the master of the order the colors of the other wizards did something to denote their magical proficiencies. For example, Radagast the Brown is a master of animals and I think botany. If anybody could help me by debunking this or filling in the blanks I'd appreciate it. The istari are maiar, spirit servants of the valar. They are the same type of spirit as sauron and the balrogs but have not been corrupted. While inhabiting the bodies of old men, the maiar/istari are essentially immortal and will return to their original forms when their work in middle-earth is complete. It has been ages since I read the silmarillion but I would say that it is the true font of LOTR lore.
US charges of 1st, 2nd and 3rd degree murder, to someone from Europe. Looking for really clear illustrations of the varying charges.
1st degree is premeditated. You planned to kill the person. Usually 25 to life. Sometimes the death penalty. 2nd degree is usually called a crime of passion. It is when you meant to kill the person however you didnt plan it out and usually if it was under different circumstances you probably wouldn't have killed them. For instance you walk in on someone having sex with your spouse and you kill your spouse or their lover. Usually 10 to 25 years with usually no death penalty. 3rd degree is when you intended someone bodily harm but you didn't intent to kill them. For instance you get into a fight and beat someone to death. You obviously meant to hurt the person but perhaps didn't intend to kill them. Usually 5 -15 years no death penalty. Manslaughter comes in two forms in neither instance did you intend to kill someone or did you intend to cause someone harm. Voluntary Manslaughter is when someone died because of you while you were doing something illegal. For instance drinking and driving. Usually 1 - 10 no death penalty. Involuntary Manslaughter is when someone died because your negligence. For instance a child runs in the road and you hit them while driving because you weren't paying attention. Probation - 5 years no death penalty. Note that murder is a state crime so each state may have different sentences or classifications but that is basically a rough definition and estimate.

If you don't get new brain cells, then brain cells shouldn't divide much, so why are there so many brain cancers?
You're right that adult neurons in the brain don't reproduce. However, there are all sorts of other cells in the brain which do reproduce. These are the cause of most cancers that originate in the brain. They include cells making up blood vessels, protective membranes, various glands, and glial cells to name a few.
If water boils and creates steam at 100 degrees Celsius, why is steam generated when we take hot showers?
Water boils at 100C, this is true. [But water can evaporate at any temperature above 0 degrees C if the conditions are right.] Boiling is when water needs to turn into steam so badly that even with all the water pressing against it, it turns into gas. At the surface of a boiling pot of water, it's easier for water to turn into gas and evaporate since the air is lighter.Water boils at 100 degrees C. Temperatures are basically a measure of the average kinetic energy of the particles — high temperature means that overall, the water particles have high kinetic energy. When water is at 100 degrees, it has the kinetic energy to just launch particles right out of the water in the form of water vapour, which then cools down again and becomes mist. Now remember, temperature refers to the overall kinetic energy of all the water particles. Even at temperatures below 100 degrees, occasionally individual particles can still have enough kinetic energy to break free of the liquid.
Why does it take a month to lose 10 lbs but it seems easy to gain 10 lbs in a week?
Something I haven't seen addressed in these answers is: water weight. Not everything you gain is fat. Some of it is bloat from eating saltier foods, carbier foods, or foods that aren't part of your everyday life. Water weight or swelling or bloat or whatever you want to call it is REAL weight, but it's not fat and it disappears more quickly than fat does when you go back to your regular eating and hydration. I know that on a holiday , I can see a 5 or 6 lb rise in the scale the next few days. That's not because I ate 21,000 calories in a single day. That's because I ate foods that were higher in sugar, salt, and carbs than I normally eat and those things cause my body to retain fluids. After a few days of eating my normal, every day diet, and drinking water, that fluid is flushed out, and I'm back at my normal weight.
Sharia courts in the UK
> Even if it is optional surely women from Muslim communities will be forced to go even if they don't agree? It's possible in any circumstance for people to be forced into doing something they don't want. The only alternative to this is to force people to use government courts to resolve all their disputes.It's not a new thing. It's not a specifically Muslim thing. It's not a specifically UK thing. For example Jewish people in America can choose to have a dispute settled by [Beth Din]. Just like the Sharia "courts" in the UK, it's just a group of people sitting down and agreeing to settle their differences using the guidance of religiously-educated people. Nothing sinister, nothing scary, nothing that's trying to subvert the law of the land.
Why in this day and age there are still places that don't accept certain credit cards?
Credit cards cost stores money. Why should they take cards unless the vast majority of their customers use them? How much business do you really think they're losing by only accepting the cards that 99% of all customers will have anyway?", 'Credit cards charge fees to the merchant that accepts them. Visa and MasterCard tend to have the cheapest fees. Last time I looked, AMEX was among the most expensive.
How if someone steels my Credit Card they can get my PIN and withdraw cash from an ATM
I had mine taken from Quiktrip in the states. It was 415 am and I was filling up on my way to work. I looked at the cube where you put the card in and the security seal wasn't there. Two days later we get charges from brazil. I knew there was probably a skimmer but there were 2 qt trucks at the other end of the station. Stupid me. BTW my card was never out of my sight the week before.There is another option inside person at the bank over-riding card PIN number. I know they can override pin numbers; I had to have it done once changed my pin and promptly forgot it. Pretty sure one of the my service guys here got ripped off the similarly. One of his staff disappeared a day or two after a big check was supposed to show up, but never did. Customer said the check was cashed.
Why can the Hubble Space Telescope take pictures of Pluto that look like crap, but can take jaw-dropping photos of distant galaxies and stars?
The photos of distant galaxies are FAR blurrier than those taken of Pluto. They only look good because of their size, and the scale of the image. If you were to try and make out an individual Pluto sized planet in that photo, it would look far worse than an image of Pluto. Imagine you are 500 feet away from a golf ball taking a picture. It's not gonna look very good. Now take a picture of a mountain from 50 miles away. It can look pretty good overall. But you are actually seeing *less* detail than the golf ball image.relevant /r/askscience thread: _URL_0_ ELI5 version:Hubble can see a certain piece of the sky with clarity of a given size. Distant galaxies and the other things seen are actually a bigger piece of the sky than Pluto, even if Pluto brighter because it is closer.Because galaxies are large. The andromeda galaxy is so large in the sky its the size of 6 moons! It's just too dim to see with the naked eye. Look, I took this picture w/ a regular camera and a tripod. No telescope, just a 50mm portrait lens: _URL_1_ Planets have the opposite issue. They're bright, but very small. So we can see the light from them quite easily, but its tough to get close up pictures.
how does a company like McDonald's make their food taste exactly the same on such a large scale?
Say what you will about fast food, but it is consistent, and that's a big part of why it sells. You walk into any McDonald's and unless someone is screwing things up, you're getting the same meal in New York as you are in Texas, Florida, Montana, hell, even Paris, et al . I once watched some special on TV about chefs at McDonald's and they said they often get a lot of crap for not being real chefs, but they just work under different conditions. Everything they make has to be easily recreated to exact specifications on a large scale to maintain that consistency, all while keeping prep time to a minimum. That is a hell of a skill if you really think about it.
What determines which foreign species are invasive and will become pest and which won't in a new ecosystem?
Yes. The criteria is whether or not they negatively affect the local ecosystem. Mangos generally don't, and can be cultivated safely. But that's not always the case. Some animals, like the snakehead fish, have no natural predators in their introduced environments. They're basically the top of the food chain in the USA, and can decimate the local fish populations while prolifically breeding. The giant African snail also carries diseases that can spread to local animals and even humans. It also eats almost any form of vegetation, including crops, and breeds even more prolifically than the snakehead fish.While the interactions of all members of an ecosystem are complex, it comes down to that species outcompeting the natives in one way or the other. A few of the factors that may give an advantage to given species are: faster reproduction, more efficient acquisition of resources, less vulnerability to disease or other environmental dangers, straight up killing the other species, etc.
What exactly is Saliva, and why can our bodies produce it insanely fast?
In addition to the existing answers, saliva is your body's natural protection against dental problems caused by bacteria. It has anti-microbial activity, so evolution likely would have selected for it as a result of:1. Destroying harmful pathogens which might otherwise infect the body as a whole2. Preserving teeth so that the individual can continue eating.
Why do toilets(in america) use clean potable water?
I had a grey water system for toilet for about 10 years. Not my house This is only sink and shower water. The bowl was uncleanable. Nasty. We finally removed the system and replaced the toilets. It's ok for gardening if you watch what you run down the drain
Why does food that is bad for people taste good, while food that is healthier tastes worse?
Matter of opinion.I like the taste of fresh fruits and vegetables more than junk food.Can't stand food from fast food or chain restaurants, they all taste the same.Over salty chemical like flavor.
What's the difference between HAM radios and "normal radios"?
A normal radio is different from HAM radio in many ways, but here are the introductory basics: * Normal radios require no government-issued license. Just buy at the store and start using.* HAM radio requires a license to use and a test to be taken and passed.* Normal radios have fixed frequencies assigned to channels.* HAM radios are frequency adjustable.* Normal radios will prevent you from breaking regulations & rules. HAM radios will not.* Normal radios use frequencies suited best for only short-distance communications of 25km . In addition to short-distance frequencies, HAM radio is allowed use of shortwave frequencies which allow worldwide communications of 4000+ km .* Licensed HAM radio operators are allowed to use very high power amplifiers of 1000 watts or more, depending on that country's rules.* Lastly, but most important in my opinion, is the fact that HAM radios can be home-build or modified. Normal radios must undergo a certification process to ensure non-interference operation. HAM radio operators on the other hand are responsible for ensuring their own and each other's rule compliance.
Why Are Peanut Allergies So Prevelant Now But Were Unheard Of 40 Years Ago?
Well meaning pediatricians told parents to delay feeding babies certain foods because they were known to cause severe allergic reactions in some people. Unfortunately, this made the problem worse because it turns out early exposure probably DECREASES the likelihood of developing those allergies. The American Academy of Pediatrics is now suggesting early introduction of peanuts , but it's too late for a generation of people who now have life threatening peanut allergies. An easy to read discussion of the issue: _URL_2_ The official recommendation by the American Academy of Pediatrics._URL_3_ NOTE: I am not a medical professional.
Boobs size [NSFW]
Hey, I'm a bit of a bra fit evangelist. I'll get to your specific, porn-y question after explaining the basics . I'll be referring to 'you', even though I don't expect the OP to need a bra-shopping guide, but because it's easier that way. 1. Measure under the chest, and usually add 0 centimeters/inches of size to get the band size. However, some brands require you to 'add 5', so the Bra Fit Wars began and much blood was shed. 2. Measure around the fullest part of the nipple, while wearing a bra that fits ; or, do I like I do, and go to a small boutique that knows bras and have someone basically eyeball your boobs and then miraculously come out with the perfect size. Then: - = cup size . The bigger the number, the bigger the boob. For more on this, existentialhero's math is important. If you want a less mathy version of existentialhero's point, with colours, go [here]. 3. Bra sizes vary from maker to maker, so the number you came up with in 2 will vary from brand to brand. 4. Boob SHAPE is also really important. For instance, most of my bras have to be full-cups because my breast tissue goes up pretty high, but boob shape also influences how your boobs 'fall' when naked. [More here]! Women who asre 'full on the bottom' tend to have breasts that hang a little lower, thereby making them look bigger. 5. Iiii'd also argue that Kelly Madison is not a 34G. I'm a 34G. Her boobs, even accounting for boob shape differences, dwarf mine. DWARF.
Why are babies sometimes so unwilling to eat, when it is fundamental for survival?
My little dude aspirated meconium on his way out. He basically had a tummy ache for several days after he was born so we had to force feed him. Interesting point though-I've often said if we were feral humans he would be in the dustbin of history as you really can't force feed a breast .
Some jobs are unpleasant but fundamental to society (eg: janitor, bus driver). Why aren't these the best paid jobs?
Because they don't need to. Simple as that. The market doesn't require it. At the current pay, they can find qualified people to fill those positions. A brain surgeon would make $10/hr if they could hire good people at that amount.
If ears and vaginas are self cleaning organs, why do people need them cleaned still?
Women don't need to shave their legs. Men don't need to shave facial hair. There are plenty of things we do for vanity. Plus, these things get clean enough for use, not necessarily spit shined.
How fiber cabling is faster than standard cabling.
There are several reasons at play here at the same time. The first is about reach. A signal will loose strength with the length of a cable. The longer the cable, the less strength it will have when it arrives at the other end. Fibre optics definitely have an edge over copper wires. I'm not sure about the actual numbers, but I believe that technical reach with manageable loss is ten times longer in fibre optics than in copper wires. The second is about reliability. When the signal arrives at the other end, you have to be able to trust it. If you can't trust it, you'll have to add functionality that handles faulty transmissions. Mathematical checksums, twisted pair wiring and very narrow acceptance levels are all things that came to be to manage that transmissions often go wrong because the earth naturally produces it's own electrical interference all the time. At the same time, laser wavelength light is manmade. There is literally no natural occurrence of it. If something interferes, it's your own communications equipment, and you have full control of that since it's your own equipment. Because it's highly likely that there is some electrical interference that you get into your communications cable, you'll be forced to for lack of a better expression *listen longer* to be sure that the signal you hear is actual data. With lasers, you can skip some of it because the uncertainty is just not there. Combine these two, and you get the reason why fibre optics are better than copper wires. They can reliably, without interference, transmit data over longer distances. And for that reason alone, they get faster. When you add to that that lasers are capable of being turned on and off real fast, and that laser sensors often react a lot faster than a regular electrical sensor and you'll end up with a system that is better in almost any way you can think of. The main issue with fibre optics is that the cable is kind of fragile. But that is outside the scope of your question.
Why isn't it law that you should be able to view your own credit score for free any time you want, as many times as you want?
For the same reason that you have to 'opt out', and pay a fee to each reporting agency for, keeping your personal information private instead of having it sold to who-ever asks for it: The Banking Lobby writes our Commercial Laws.
I feel like I'm decent looking but why do I look uglier in pictures?
Something I didn't see mentioned: some people are uncomfortable around cameras, and even more so around video cameras. We become self conscious and try to pose. The only pictures where I don't find myself ugly are the ones where I wasn't aware a picture was taken. I hate it when my mother pulls out her camera at every familly gathering, I try not to look at it so I won't know when she takes the pic. What makes it worse is she will make people stand still for 2 minutes with a fixed fake smile until she figures out which button to press.If the photograph used flash it is extra bad. All the proper forms get flattened out and you can see a lot of reflection in your skin so you see all of the imperfections and protruding brow etc When you look in a mirror you might be getting nice "top-down" lighting sorta similar to a movie or something. This "key light" might be soft and you will get nice shadows and warm lighting. You just get the impresion of yourself at a glance. But in a photo you can see yourself up close. All the oddities. Especially if the light is blown out like in the sun / convention center / or with flash. Flash is the devil. Also. Field of view can make people look less desirable. The more flat the perspective the better some people look. No joke for some online dating pictures i 've taken pictures of myself from further away and then cropped the image.
Can someone explain to me the collapse of the Roman Empire?
It's a tough subject to explain to a 5 year old so I'll only mention what is the main point in my opinion. Imagine you are the head of a student council. Your school is very big and is generally absorbing more kids into its school system. Every time the school expands, it is tradition that the new kids have to do all of the work around the school . Things are going well because all of the older school students can live without having to do the bulk of the work. Eventually though, your school stops expanding and there are no more new kids. So you have nobody to do the work. You expect that the older students will do the work, but they want payment. Your school starts becoming rundown because not enough work is getting done and your people just aren't doing as much because you no longer have cheap labor. Because of this, when other school systems want your kids, they are much more willing to be apart of a different school system. This resembles the issue of slavery. The Roman economy depended on it. However, once they stopped conquering and expanding, they stopped getting slaves. Romans stopped producing as much and the economy fell to shambles. Their military lacked strength and when barbarians started taking land back, Rome did not have the capability to fight them forever, although they made some good stands.
Why must vaccines be given as a shot and not simpler forms like pill, patch, etc.
Has to be directly injected. The body could 'digest' the vaccine before it could be absorbed and reach the bloodstream. If I remember correctly, they can make anti acid coatings and such, but the procedure can kill the antigen/virus. And clinical trials.
Why is soccer able to dominate the TV ratings worldwide as a spectator sport yet not even be a blip on the US TV ratings?
because americans don't play football .more or less it's about a country's sport culture and with which sports are people more familiar with .e.g greece has 2 of the best basketball teams in europe and our national team was among the best in the world yet everyone prefers a corrupted football league with teams that can barely make a difference in european soccer and a national team that luckily won the euro championship in 2004 and then faded into mediocrity .it's about what you were raised with .i for once haven't played or watched baseball ever and frankly speaking i think i'd find it boring as hell ,yet it's a huge sport in the US .also car-related sports are an entirely different matter .i never drove an f1 but i'll sit in front of my tv and watch the entire race like most males would do cause high speed and cars are a part of our personality
If a none-married couple have a child who's surname do they take on?
it's a social norm to take on the father's last name, but there is no legal requirement. since mother is always present at time of birth and the genetic father is not present or unknown, it's her choice.This is actually determined by law and can differ from state to state. Selecting [Florida] as an example : 1. If both parents are married and have custody and agree on the name, that name goes on the birth certificate.2. If both parents are married and have custody but disagree, both surname are placed on the birth certificate separated by a hyphen.3. If both parents are married but only one has custody, the custodian selects the name.4. If the parents are not married, the custodian choses the name. In the case of 4 this would either be determined by a court order stating who will have custody. If no such order exists, then the mother has default custody, and would get to choose the nameIt changes from country to country. In Brazil, for example, a child must bear both parents surnames . The only exception is when a father doesn't acknowledge a son as being "his", which will make the child bear only the mother's surnameI was born out of wed-lock and was given a hyphenated last name of "father's last name - mother's last name." When my parents got married, they changed it and I now have only my father's last name.
Why are children so inclined to eat their boogers? Are there cultures where the social stigma around eating boogers doesn't exist and booger eating continues into adulthood?
I see grown Japanese men eat their boogers while their wives nonchalantly look on almost every day on the subway. It was pretty shocking at first Have yet to see a woman do it , so I'm not sure if it's a guy thing here or a culture thing.Membranes in nose create mucus. Most mucus travels backwards and is swallowed. Small amount of mucus ends up travelling forward. Mucus in nose is uncomfortable, and blocks air. Pick it out. No where better to dispose of it. Eat booger. ??? Profit', "When you're a kid you can never really be bothered looking for a tissue. So you have some uncomfortable snot, you get it out, you don't really know where to put it .so you eat it. It doesn't taste too bad, so you do it again. Makes sense in kid logic.
What is the psychology behind a victim of verbal and emotional abuse who desires their abuser once the relationship has been broken up?
Neurons that fire together wire together. If you're a victim of verbal/emotional abuse in childhood, chances are you become conditioned to associate abuse with affection, attention, etc and subconsciously seek out similar relationships as an adult. It's all a habituated process, really.
If the black plague still exists, why doesn't it spread rapidly like it did in the 1300s?
Vector controls. Better sanitation, health providers are more advanced. The biggest issue after a natural disaster is the clean up. Why? Pests, pests carry diseases. When our infrastructure takes a hit, sanitation cannot do it's job. Thank your garbage man, without him, our society would go to total shit and that's the truth.My bet would be the improved hygiene. We no longer have rats running through the streets, we bathe which discourages fleas, and we have this thing called medicine. The black plague was spread to humans by fleas and between areas by rats.
How do huge businesses like airlines start? Not many people have enough money to just buy airports and planes.
In short, this is the story is the evolution of capitalism and firms. Early on in capitalism families of traders pooled resources and spread risk to send ships of goods across oceans. As we developed more formal systems of contracts and governments that enforced them it allowed people not bound by blood to come together the pool resources and spread risk. On example is Lloyd's of London and insurance marketplace that allowed merchants to insure their ships voyages . Over time in particular the modern corporation has evolved to allow massive investments to be undertaken because the necessary resources and risks can be spread so widely through various economic tools . TL;DR Modern Corporations spread necessary investment and risk over many people.
Why is it possible to install a wide variety of generic operating systems on just about any computer, but a custom ROM has to be developed for every smartphone?
It mostly comes down to drivers. Unlike PCs, drivers on mobile devices are kept pretty close to the chest and aren't generally released to the public. So ROM developers have to write their own custom drivers or try to reverse engineer the already existing ones to get the phone working in a custom ROM or in an updated Android version. Then, there's also trying to get the device OEMs to release the source code to the Android kernel that they used for their device. Without that, it's pretty impossible to develop your own custom ROM.
Why do some phone cases or watches say water proof up to a certain amount of feet (like 6ft)? Is it the water pressure difference? Is the water pressure difference that significant?
One thing to consider: When you jump in the water, swim etc. the pressure can exceed the ones on the label. Most watches are water proof for at least 3 atm - but that doesn't mean that you should use them if you go swimming. Dive watches on the other hand are usually at least water proof 300 m or deeper. It is measured in the laboratory, with a still pressure head .Yes, it is the water pressure difference, and yes, the water pressure difference is that significant.
Why is it that a large number of American students choose the high cost of their University over studying abroad?
Tertiary education is expensive worldwide. In some countries citizens are able to get significant discounts due to government subsidy, which international students don't qualify for. Beyond that, international students will usually have strict visa requirements, this may limit how much they can work while studying, and it may be very difficult to extend the visa . Attending a domestic university is comparatively flexible with this regard.
