Why is tar associated with dinosaurs in fiction?
They act as traps that could kill even large animals who couldn't, then, be further disturbed . The substance is very difficult to escape. As a result, they are *awesome* sites for ancient fossils. I would surmise this leads to the association with ancient animals and tar pits.
Why are things that are hot to the touch, not so hot to the mouth i.e. Coffee?
Also your mouth is use to internal temperatures of 98.6degrees Fahrenheit but your skin is use to air temperature which is often closer to 75 degrees Fahrenheit. So if the coffee is 100 degrees then it's only a little warmer than what the mouth is use to but a lot warmer than what the hands are use to.Is it possible that it also has something to do with your mouth being moist but your hands being dry? So basically the liquid covering the inside of your mouth cools down the hot tea/coffee before your cells can actually sense the change in temperature. Sorry for the lack of scientific terms, I could explain better in Hungarian
I'm generalizing but, why do people hate insects but like/tolerate reptiles?
Some reptiles look pretty weird and scary, but they still follow the typical formula of four legs, two eyes, a tail. It's familiar. Insects however, have tiny body parts so you can't clearly see it's face . Bugs also have several legs, can have really strange alien-looking mouths and eyes compared to weird reptiles. We also associate insects with filth and disease, a house with insects is dirty and unhealthy, but a house with geckos probably just has a lot of geckos living around and it's perceived as more harmless. As for stuff like crocodiles or large lizards, sometimes we admire their exotic strength like many people do with big cats.
Why the facebook chat list is structured that way, and why people I haven´t speak with in years are located near the top?
Couldn't the algorithm be tested? Like you have a couple of people create nearly identical accounts and friends lists and see how interactions affect the list?
Where does all the school funding actually go?
School funding covers everything from heating schools to paying administrators. It's not really going anywhere it shouldn't go except in a few cases of corruption. In general, schools need to be funded better period. Teachers often have to purchase their own materials on a low salary to begin with, and teacher burn out is high. Not a great work environment. A big issue with school funding is that it is often tied to property tax. Richer areas have richer schools, poorer areas suffer.[Here] is the budget for Orange County, FL, which is the 11th largest school district in the country. See page 8 for a breakdown in revenue and expenses. Half goes to instruction . The rest is divided over everything else that the school district pays for, from building new buildings to keeping the lights on.
How are key/door/locks makers manufacturing so many keys/locks etc. without ever repeating a combination? Or do they repeat them and hope no one will figure out they have the same key combination?
There are only so many key combinations, but if you have 5 pins with 5 positions, that's already over 3,000 possible keys. Even if every lock used that same key shape -- and they don't -- it's highly unlikely that you'd coincidentally stumble across a duplicate. On the other hand, some older keys have far fewer combinations, which can be a problem.Outside of the car answers, they most definitely repeat. Go to the hardware store and look at the locks/knobs. They have a code so that you can buy all locks that work with the same key. There are many combinations, so the likelihood that you could guess the house that has the key you have is near zero.
If the universe doesn't have borders, will an object travelling forever in a linear motion eventually arrive back on its initial spot, or will it keep on distancing itself from it without ending?
We don't know if the universe has borders, it likely doesn't afaik. When you hear the universe is expanding it doesn't actually mean what you think it means. It means the graph paper itself is expanding.All the answers can be tl:dr as such :We do not know and any answer is a make believe answer there are no knows about this. And it's all speculation. We have no clue what the universe is , how it began , when it will stop , what the nature of it is , if it has a real beginning or an end , we don't know if there is an edge , if it's an expanding bubble etc. It's all speculation. Any answer beyond "i don't know" is is fake as hell. Here be dragons!', "The object will continue traveling farther away forever. But that has nothing to do with whether the universe has borders or not. The visible universe is expanding, and it's doing so faster than the speed of light . We don't know what's beyond the visible universe, and for the most part it would be impossible for us to ever know. Because of the expansion we can never reach the edge of the visible universe. Even traveling at lightspeed for eternity, the portion of the universe any object could actually reach is steadily shrinking.
Why is it important to do stretches before exercising (i.e. pull-ups, push-ups, weightlifting, etc)?
**Do not stretch** before doing exercise because of increased injury. It's also a **huge waste of time** It is important to warm up. Warming up means doing a lighter version of your exercise, like walking before running and light weights before heavy. Warming up reduces injury by getting your body 100% ready for the upcoming exercise. You can further improve your exercise by massaging muscles regularly. Massage increases the blood flow and helps you relax. Tight muscles are weaker and can damage your skeletal system. Stay curious :)
How planet's rotation affects on day length? How is that related? And If I lived on 12-days-planet, then my age will be half?
Measure your height in inches, and you'll get a larger number than measuring in feet. The larger number does not make you taller. Measure your age in Saturn-days, and you'll get a larger number than measuring in Earth-days . The larger number does not make you older.
Why isn't Lena Dunham getting the same treatment as Josh Duggar when they did the exact same thing?
I think it's because the Duggar family has a very different image than Lena Dunham. So, they're held to different standards and judged in different ways. If you know anything about Lena Dunham or have ever watched her show Girls, then it's not the most shocking revelation in the world. Whereas, it's a lot more surprising when one of the Duggars does something like that. I think also, there may be the male/female bias but also, Duggar molested several more people than Dunham and the Duggar family knew about it and tried to cover it up. So, I see the point you're trying to make and in some ways, its the same but in other ways different. I'm not really surprised that people would react differently to the two things.How can a 7-year-old be guilty of child molestation?', "> She fiddled with her younger sister as a kid, wrote about it in her book, got all pissy when people called her on it. Also, she made a false rape claim against a guy she went to college with. Got all pissy when she was called on that, too. She's a pretty disgusting piece of shit IMHO. As the sidebar says: > Don't post just to express an opinion or argue a point of view. You clearly have a point of view. Try /r/changemyview instead. This thread has been removed.Out of the Loop here. What did Lena Dunham do?
Why do car companies make average, everyday autmobiles capable of speeds any higher than 80-85 mph?
You shut your goddamn mouth. I want to be able to drive 145+, don't give them any ideas.Fast = FunNot fast = Not fun', "Because people aren't all emasculated sheep who want to putz along from their mundane job to their boring apartment and back. Some people want performance. Some people know how to drive. Also, some people live in wonderful places where the speed limit IS 85. In order to do 85 up a hill, you have to be able to go a lot faster than 85 on level ground or down a hill.
When you're swallowing food or a drink, and you accidentally swallow air with it, what is that intense pain in your chest and throat that follows for several seconds?
Food gets in your stomach by being pushed down by rhythmic muscle contractions in your esophagus . You can't really force air down as well as food, so those muscles squeeze harder, and the pressure increases in your esophagus. That high pressure is that pain. Stretching any hollow tube in your body with air is super painful
Why are Republicans so opposed to Hillary Clinton running for office?
No matter who the front runner for the Democrats in 2016 was would be targeted, but Clinton is a special case. Michelle Obama only really advocates for relatively non-controversial issues as First Lady - kids getting more exercise and eating better, for example - but Clinton was the face of health care reform in the early 90s. The shitshow that was the fight over Obamacare has happened before, and it was called Hillarycare then. So basically, she's been a national figure for a couple decades now , and there's always been the prospect of her running for president, so Republicans have practice in hating her.
I've heard shower sex is uncomfortable, why is water such a bad lubricant?
It really depends how wet the female is. My wife can gush when she's horny so wether we are in the shower or not it's like playing with a hot dog on a slip and slide. Edit:a word.The same reason most lubricants are hydrophobic.. Water has a cleaning effect which removes oil from the skin making it feel rubberish.. Tires grip the road and are made of?Because a womans "wetness", or "natural lubrication" if you will, is a type of Mucus, yes folks, that nice slippery wetness is Snot. Water is too thin to provide lubricationIs it uncomfortable? I must be doing it wrong My personal experience with the matter is that the water is just too much and provides barally any friction. Making the whole experiance just sorta ehh. Now shower blowjobs are a whole nother story. As /u/mingilator said silicon lube. Which is best for anal.Water is a solvent, not a lubricant. It therefore will dilute the body's natural lubricants and lead to an uncomfortable wet skin-on-skin session of awful sex.Its because the water dilutes the natural lubrication and washes away natural oils that keep your skin protectedAll these people talking about lube For me the greatest issue is the difference in height!
Why are mines resource specific (Iron, coal, etc), instead of general purpose?
Certain equipment is required to extract/separate any particular mineral. It takes time, energy, and upkeep to operate it. As others have mentioned, rocks rich in *a certain type of mineral* tend to occur together, but let's assume there is an area with natural gas and gold. But instead of 2 units of gas or 2 units of gold, there is 1 unit of each. You still need to break the rocks while underground to release and capture the gas . And you still need to haul them up and smash them to get the gold out. Neither step of the process made the other step easier or cheaper. Yet in this example, each step produces only 1/2 what it would in a specialized mine. Even if a rock existed where almost every part was useful, the cost of extracting/separating everything you want is not necessarily less than traditional mines.
Why do we have certain dreams that are 'repeated'?
Dreams are to solve your waking problems. I have dreams that I remember every single night. There have been many times I have woken up and felt that a dream had addressed a problem, or prepared me to approach it. You're the one who actually creates the dreams. You have control over what happens, a lot of what you dream is actually something you want to think about. Have you ever been so obsessed with a thought that even after you fell asleep, you started dreaming about it? Dreams are influenced by what you have to think about. The repeated dreams are when you have a problem and you are revisiting it. Sometimes there are dream locations you haven't visiting since childhood and you revisit it. Often a way of yourself to understand a problem you haven't since you were a child. That said, dreams are very dependent on the person. Some people who are very reflective end up having more powerful dreams than those who aren't. Source: Dreams a lot.
EVE Online. I've heard all the Excel jokes, but how does the game actually work?
The other answers here are excelent, but I'd like to touch one thing. The Excel jokes are mostly because spreadsheets present a ton of info in a compact and understandable way. IF you're interested, [Here] are some videos from the latest CCP FanFest. Some highlights you might like in regards to your questions. [EVE Economy] [Merging Economies]
With regards to the weather, Why does a low pressure system result in low temperatures and high pressure system result in high temperatures.
polar high", and "arctic high" do exist. This [page] should shed some light on the matter.
Why does government still allow people to buy cigarette, despite the strong link between cancer and smoking is obvious?
It's very difficult to ban things completely and it costs a lot of money to enforce a ban. On the other hand when you sell dangerous goods you can add extra tax that helps pay to fix some of the damage, like helping to pay for the medical costs of smoking diseases. That means you have to balance whether banning something will make the overall situation better or worse, as if everyone still does it but the government isn't getting any money to help fix the damage then it would have been better to not ban it in the first place.Now you have created a black market commodity OP, meaning a black market will form around it, just as it did during prohibition. People will still go to great lengths to supply and buy tobacco, massive illegal business will form, and who knows if the tobacco they are buying is not poisoned more than it already is.Because the government shouldn't decide what the private citizen wants to do as a personal choice.
Why do humans tend to get congested after a night of drinking?
For me it's the tannins in wine. They give me a very slight allergic reaction. I can't drink more than about 4oz of wine without starting to feel bad, a headache creeps up on me far more easily on wine than on beer or even liquor. White wine has fewer tannins so I can drink it more easily. My mom gets a much worse reaction than I, getting some real congestion from red, so she avoids it. There's tannins in lots of foods, like tea, but for some reason none of them bother us like wine does.
Why won't gas prices go back to pre-9/11 prices if we are producing as much if not more oil?
A lot of young people are posting about inflation and stuff. Gas was $0.54 for regular in 1999 at exit 1 on I-95 in Georgia . The first time I paid more than $0.99 was 2003. It has nothing to do with inflation and the price increases have had very little to do with supply. Oil companies have simply increased their profit margins. If oil companies reverted to the margins they had in 2000, you'd be paying about $0.85 a gallon.
How can my computer mouse accurately detect distance and direction, despite my mousepad being entirely one color?
Well, your mousepad might seem uniform to you, but to the computer mice it isn't. By taking thousands of pictures per second and comparing them, they can see in which direction they are moving. Thing is they're not looking at what is beneath them, but at the fabric/texture of whatever surface they're resting on. Put them on something perfectly flat and they won't work.
How did France lose to Germany so quickly in 1940?
The Germans implemented the very risky Manstein plan. It was an all or nothing attack. If it failed then Germany would basically be doomed. However, there were many problems with the French who on paper had the Germans outmatched. The French military was full of unimaginative officers who ignored everything that didn't fit their already preconceived notions of what would happen. They weren't able to adapt to the fluid nature of the war which the Germans forced upon them. The Germans may have been weaker on paper but they made the French react to them.Military bureaucracies are as slow as church bureaucracies. They tend to prefer traditions to reason. Ideas become accepted funeral by funeral. The French were not prepared for the [mobile warfare doctrines] the Germans had developed only a few years before. Most of the French training, equipment and strategic planning was oriented on the experiences from the trench warfare of WW1 with its slow and inflexible movements of troops and supplies. So while the French had superior firepower on paper, this firepower was never available where and when it was needed. The German units moved at a speed the French could not adapt to. This is exemplary for the German mobile warfare:_URL_1_
How did we land on the moon and why do we really need to think about it on how to land on Mars?
Mars is a bit more difficult because compared to the moon, it has more gravity and it has an atmosphere. Our attempts at landing probes there have been tough and they've seen rough landings. It would be a lot like landing on Earth , except no one will be on the surface guiding the pilot.
Why can't we build a subway or tunnel from the US to Europe?
A vacuum tube coupled with a maglev train would allow speeds in excess of *4000* miles per hour or 20 minutes from N.Y. to L.A. A tube floating in the Atlantic and anchored to the sea bed could reduce cost and avoid turbulent seas. Many ideas exist but they cost so dang much. Easily trillions on unproven technology. One day it'll happen. Just the haulage market would be so massive it would pay for itself eventually. Heck, point one of the tubes up and you'd have cheap orbital launch. _URL_0_", 'Good answers already but I would like to submit that is is 3,459 miles from New York to London. Even driving at highway speeds that would take two days to travel. So you would need various gas stations and hotels along the way.
Why I see patterns and swirls when I'm in complete darkness.
I just want to share an experience. I was in a cave, one of the only three places where you can get absolute darkness , and there was this glow, like an electric watch that was dieing, a very faint slight glow and I SWEAR it was there! But after putting my hand over where I think my eyes were , and it didn't go away immediately, I'm doubting it. You mind truly does play tricks on you.
Some people say Obama lowered the deficit, some say he raised it more than any other president. Who is right and how can there be such a gap in analysis here?
Let's stop committing a fallacy in this thread by attributing government spending to the President. The President signs the spending bills, but the Congress passes those bills. All the credit and all the blame should go to the Congress. Yes, the President may propose a budget, but it can't happen without the Congress. Too many people think the President does everything and ignore their Congress-Critters, leaving them in office for far too long
Why we can take detailed photos of galaxies millions of lightyears away but can't take a single clear photo of Pluto
Imagine a galaxy as a spotlight a mile away. It's really bright and easy to take a picture of. Now imagine Pluto as a golf ball across the street that is moving very fast. That would be pretty hard to snap a clear picture of.
Why Libraries Aren't Illegal
Libraries loan hard copies of media. If I let you borrow my CD or book, that is perfectly legal because I purchased it. At the time you are using the media, I no longer own it. Now if you where to make a copy of the media that you borrowed, wrather that be from me or the library, that is illegal, but it isn't my fault.
How do movies and TV shows deal with actresses getting pregnant?
There's all kinds of tricks. Postpone filming key scenes until after birth, or change the shoot to only include shots from the shoulders up, put them in baggies clothes or try to keep them standing behind things. Writing wise, you can make the character pregnant too, or come up with an excuse for them to be away for a few episodes, or turn their character into a head in a jar
Why do some people faint when they see famous people (on concerts, etc.)? What happens to their body?
It's a stress/emotional response. When you are under intense stress, your body goes into emergency mode and a number of things happen. You get a rush of adrenaline to help you to either run away or fight to defend yourself, most of your non-essential systems such as digestion shut down and your blood pressure goes through the roof. When it comes to fainting, if your blood pressure suddenly drops while you are in this emergency state, your body will take steps to re-establish blood flow to your brain. If your blood pressure is critically low, your body can't pump blood upwards to your brain fast enough, so it needs to get you to lie down, and to do it *right fucking now*. The best way to make you do so is to deactivate your muscles and have you flump to the floor so that blood can flow to your brain more easily. This response serves a double purpose since a common cause of a sudden drop in blood pressure in an emergency situation is severe injury resulting in heavy blood loss. In this situation, it is advantageous to play dead in order to end an attack. Your body is doing just that, playing dead, getting you laid flat and re-establishing blood supply to your brain. Your sympathetic nervous system is basically performing a hard reboot.OP, was it the HBO special Live at Bucharest? I remember seeing that back in the day, and something like 20 people were being carried off when he was standing onstage before the first song even started
How do companies make money by giving huge bonuses to new hires?
Hypothetical example, Let's say a company needs to hire 100 new employees. The productivity of these employees will make the company 10 million dollars. With the salary they're offering, they can't find 100 qualified employees to hire. They can raise salaries, pay bonuses, or not hire the 100 employees, and not get the extra 10 million in profit.
ELI where the heck Pinterest came from, and why am I hearing so much about it in just the past 30 days?

Why do criminals who robber and became rich/set for life, go and rob again rather than just disappear and enjoy life?
Most crimes do not make you set for life. Even if a criminal was willing to live on a 35k salary style life , a 25 year old would need to steal, let's say enough for 60 more years. That's 2.1 million dollars. And that's if they did it solo. Assuming they have any help they need to split with, or take less than that , or they want to live a slightly more extravagant lifestyle than 35k a year for the next 60 years , than that one robbery won't come close. A team of 3 criminals that want to live a 50k a year life and get 200,000 a crime would need would need to commit that crime every 1 year and 4 months for the rest of their lives.
if warm air rises, why is it colder the farther you get from the earth's surface?
Air can hold energy, namely in the form of heat. The more air there is, the more energy that air can hold. As you go higher from the earth's surface, there is less air. Less air means less energy that can be contained.
For all the money and research, why haven't we cured cancer?
Cancer is a disease which comes in many different forms. It's caused by a mutation in one of your body's cells. There are many different mutations that can cause cancer, and depending on what kind of cell it was starting out, its location, and the specific mutation, the characteristics of the cancer vary widely. Additionally, because the cancer cells are the body's own cells, it's very difficult to target them. Anything you can develop to kill cancer cells will kill healthy cells too.Cancer is our own cells, mutated and reproducing out of control. There is no guarantee a cure exists. Anything that kills cancer cells will kill our own healthy cells, because they are both human cells. Nevertheless, we have many more treatments available now than before we invested so much into research.
Why can you see the moon in the daytime sometimes but other times you cant?
Because, sometimes the moon is in the sky during the daytime. Sometimes it's on the other side of the world, and there's a planet between you and the moon.
What are the down sides to drug testing for welfare and food stamps?
Regardless of rights' violations, the biggest argument *against* drug testing I have heard is that if the recipients fail and lose their benefits, it is likely their children who will suffer. No food in the house, no soap, no new shoes, etc.Arguments against: * it is expensive* it indiscriminately treats infrequent users they same as hard core addicts* it reinforces the failed punitive policies of the War on Drugs', "Downside = waste a lot of money Upside = ??? If you don't want to pay unemployment to drug users, then that could be your upside. It's the principle of the matter, that you don't want to give drug users money. If you want to save money by kicking off drug users, you actually spend more money drug testing then you would save by having fewer people to pay. Because you have to drug test *everyone* constantly, be it once a week or once a year.
Why do men and women look so mature in the 20th century despite being late teens/early twenties compared to now?
With regards to men specifically, there's a common belief that exposure to the estrogen-like compounds found in modern plastic is making them more effeminate and delaying puberty.
Why are guilty plea's of value to the state?
It's like the OJ Simpson case. A guilty plea is better than a criminal getting let off either because a jury can't convict or due to procedural mishandling. Kind of like a bird in the hand is worth 2 in the bush
As a Englishman who sees universal healthcare as a basic human right, why are such a large proportion of Americans so opposed to free healthcare, even those who would benefit hugely from it?
Well actually I have a question for you about healthcare being a right. That 'right' has to be performed by someone else. If you have a right to care, then what right does the doctor/nurse have? If this is not voluntary then that means they are being forced to treat you. Or if they're not being forced, someone else is being forced to pay them a fee to treat you. What I see as the problem is that the 'good' that is being done is being done by force and not through voluntary cooperation. Can you weigh in on this?", '> "I guess the trouble was that we didn't have any self-admitted proletarians. Everyone was a temporarily embarrassed capitalist.

Besides they were too busy fighting among themselves."

Why do small animals move in quick twitchy movements?
Don't most smaller animals also have MUCH higher heart rates too?", 'Has to do with their nervous system. There is something called the myelin sheath and because they are small they have less of it, so their motor movements are jerky. I wish I could explain it better but I do know that it stems from their smaller amount of myelin sheathOur brains are designed to focus on "something new" in our visual field. We block out stable images and focus in on moving or changing images. Small animals move in such a way to reduce the amount of time they spend moving so as to minimize the time a predator has to notice them. So they jump from position to position with near perfect stillness in between movements. Edit: Here's an example of how stationary objects "disappear" because our brains are focused on motion: _URL_6_Quick and twitchy animals have muscles comprised of more fast twitch fibers. These fibers do not require oxygen to use, anaerobic, and allow an animal to move very quickly for small periods of time compared to animals with slow twitch fibers which use oxygen.What a bunch of smart sounding b.s. answers! Small animals' brains can't process fast enough all of the sensory data that it receives from high metabolism animals. They have to stop in fits for their brain to process. The Tiger Beetle, for example, moves so fast that it temporarily goes blind. See the link below for a start: _URL_7_", 'I think the question is not why small animals make quick movements but why big animals make slow movements. I think the answer would be because bigger animals having more mass move slower. That is why in the case of movies/shows, giant mondters movr exceptionally slower.Compared to blue whales, humans are extremely twitchy. It's relative to size and metabolism more than any other factor. Hope this helps.
x-raying a celebrity's photo
xraying only works on skintight, thin material, without any fancy patterns on it, and preferably white. It won't work through a swimsuit, or most dresses, or most underwear.

Why do some people consider real-life "not enough"? Constantly wishing it were more fantastical in some way rather than finding enjoyment in its current state?
Dissatisfaction is hard wired into our brains. The instinct that makes people dream of more fantastic versions of reality is the same one responsible for the ambition to succeed and move up in one's job, or to excel at athletics or games or whatever. For prehistoric humans it might have been an advantage for security and contentment to be fleeting because that would encourage us to chase them. Being unhappy with their surroundings causes people to complain about them and imagine what might be better, which is crucial to the survival of a species whose success has been based on an ability to adapt it's surroundings to help it survive changing conditions. TLDR: complaining helped us survive in the prehistoric era
If cancer exists in someone's testicles (or any other body part), why can't they just cut them off and have that be the end of it?
If it's auxiliary piece , sure that might work. For more vital areas it's a bit tricky since you don't want to cut out what's underneath. In addition, cutting haphazardly can actually spread the cancerous cells to other parts of the body as well as dislodge them into the bloodstream.We can. I lost one of my testicles to cancer, and have been cancer free since its removal almost 5 years ago. The doctor said we caught it crazy earlier, so that may or may not be a factor in how easily it was removedTo answer your first question, the standard of care for testicular cancer is surgical resection of the affected testicle. This is true of most superficial, or easily detected and localized cancers The unfortunate aspect of cancer is that it is often detected late, and after there has been metastatic spread. It's not as easy to find things like ovarian cancer as it is testicular cancer. Usually symptoms are first just "general" things like bloating or constipation. By this time, the cancer has spread to other organs, and cavities. Furthermore, there might be lymph node involvement, or currently microscopic metastases that won't be picked up by other scans. These stages of cancer is better treated by radiation or chemotherapy. There are many, many types of cancer that all have their specific guidelines that physicians use to stage, and treat them. Look at the NCCN guidelines for more informationThey can. They do. Why is it not "the end of it?" Because we can't be *sure* that cancer didn't spread. Better to go in and get regular check-ups to see if it turns out it spread, than assume it didn't. Also, you developed cancer for a reason. For whatever reason, you're more at risk to develop it again. Better go in and make sure that didn't happenIt happens, but usually, people are attached to their body parts, both literally and figuratively.
Why do successful bands break up, when staying together would be lucrative?
Because money is NOT everything they care about. As artists the idea of being creative and independent has a real impact in the work they produce. For some, after some years that's no longer the case so they simply prefer to part ways. In other cases, artists have huge egos and when some band members have more visibility than others it creates an unsustainable environment.
How come getting tattooed isn't a big bloody mess?
When I got my tattoo there were was plenty of bleeding. It was tiny little globules of blood coming where the needle just was. As others have said it's a tiny puncture so blood doesn't come pouring out like crazy. The artist was wiping vaseline or similar onto the tattoo as he wiped the ink away which slows/stops bleeding as well.Most of the blood is below the epidermis - needle just doesnt go far enough. _URL_1_
If carbon dioxide is toxic, how come breathing in and out of a bag doesn't kill us?
While large amounts of CO2 is toxic, your breathing isn't 100% efficient. You don't extract all of the oxygen in the air you breath and you don't exhale pure CO2. Eventually re-breathing the same air would kill you but in moderate amounts it isn't a problem.It’s not toxic. Excessive amounts and lack of sufficient oxygen in the mix will suffocate the breather.
on the news this morning, it said that our co2 levels are the highest in human history. what does this mean for us and our planet?
Let me put it like this: Venus is a lava planet that rains battery acid because it's atmosphere has too much CO²
Why does running water make people want to urinate? Wouldn't a source of fresh, moving water be the LAST place for our ancestors to contaminate with human waste?
I think it's just a sort of Pavlovian conditioning. What do you hear every single time you take a leak? Splashing/running water. You smell a tasty burger on the grill, maybe you suddenly get hungry. I know I do. So you hear trickling/running water, maybe it brings your attention to the fact you kinda wanna pee.Heard from a nurse. It seems pretty common trick among them. I believe it is just suggestion or a social bonding effect like [yawning].I honestly never even *heard* of this until I was an adult. And the sound of running water simply makes me want to get off the toilet to turn it off so I don't waste it. Maybe it's to mask the sound of urination for the shy and squeamish? After all, our simian ancestors we're at their most vulnerable when they were either at the drinking hole or relieving themselves, so maybe that reticence to be heard is an instinctual holdover?
When you take out the CPU, RAM and Video Card, what distinguishes one laptop brand from another?
Besides the CPU, GPU, and RAM manufacturers have control over battery life, aesthetics, build quality, screen size/quality , weight and most important customer service. One company may have a better track record when it comes to customer service and honoring warranty's etc. Look at the materials used to make the exterior.
Why does water change its course when it's flowing down a window?
Ian Malcolm from Jurassic Park explain this perfectly: _URL_0_ Like /u/daninmontreal, it's due to microscopic changes in the surface of the window from things like dust and wind.
Why are some people able to consistently avoid hangovers, while others pay for each shot with an hour spent in fetal position on the bathroom floor?
Short answer: Water I never get hangovers. The reason we get hangovers is because alcohol dehydrates your body. The trick is to keep your body hydrated throughout the time you're drinking. I drink a glass of water for every couple of drinks works for me but perhaps there are other biological factors that come into play so it may not work for others.
Why can I binge watch a TV series but after one movie I feel like I need a break?
I think that taking a short break for your eyes to rest or grab a drink or whatever is definitely a part of it but I think it's a psychological thing. I have had times when I am dead tired but I continue to the next episode because I want to know what happens I have to know what happens. TV Shows are experts at using this tactic. Just the same was as a copywriter gets you to read his next sentence or a book gets you wanting to read the following chapter. With movies you don't really have this problem because it's a given that unless you fall asleep or something comes up that your going to sit through it. Basically the answer is TV shows use psychological marketing tactics within the show itself to hook you into the next show.I believe most people have already said this but: The main reason is simply because TV shows are geared to have more content in them, more buildup between episodes. You know those cliffhangers some episodes leave you with so you just have to click the "Next Episode" button? Movies are setup as a beginning, buildup, climax, and a conclusion all in one. When you finish a movie, you 've just finished an entire story, learning new characters and watching it all conclude in a few short hours, whereas a tv show you get invested in over time and are watching the continuation of a story instead of an immediate conclusion.A series has continuity and a story and a theme that carry over. It's also usual for a tv series to end episodes with suspense, inciting you to watch the next one. A movie, unless you're talking of a series like LOTR, has an ending. Even a series like HP where the story carries over, has a different setting and a plot for each of the movies. Moving from one to another needs a break since it's harder to make such a quick transition from one story to another.
How is it possible for Netflix to crack down on all VPNs/Proxies in an effort to curb users accessing content outside their countries?
Couldn't they just compare your address from your payment method to what the server is reporting? Seems rather easy. Oh this customer is using a card that is based in India, but the server keeps reporting Teaxs.
Why do web browsers run multiple processes whereas most other software can perform tasks just as complex with a single executable?
If I remember correctly chrome runs every app or add on in one Web page as a separate process. This means that if one part of the Web page fails to load the entire Web page won't be stuck waiting on that one part. And you can stop one part while continuing to load the rest.
Water is a great conductor of electricity, salt water is even better. So how come lightning strikes in the ocean don't kill thousands of fish daily?
Some people have answered part of your question, so I'll just add something. The reason that the strikes don't cause much damage over a wide area is because of the [inverse-square law]. From the point of contact at the water's surface, the energy travels in a hemisphere outward. As the distance from the point of contact increases, the amount of energy available from the strike is spread out over a larger and larger volume of water. This is the same principle that causes a flashlight beam to become diffused and useless over distance -- the same amount of light is being spread over a larger and larger area.
Why did the Olympic committee decide to cut out wrestling?
Several reasons including: 1. It has gone down in popularity on TV 2. In the US its shown at incredibly inconvenient times ,which alienates a large amount of viewers 3. It doesn't seem to bring in the big money like swimming, basketball, etc Its incredibly unfortunate that the oldest sport in the world is getting the boot.
Are 2 in 1 shampoo and conditioner just shampoo and conditioner mixed together or is it a different chemical?
I've always wondered this too because I have very long hair and sometimes I run out of my shampoo and end up using some of the 2 in 1 that's in my shower, which basically just seems like shampoo to me. I definitely don't get the effects of conditioner so I always try to avoid it or else my hair will end up being really tangled still.
How come a such large portion of the US population doesn't own a passport? How do they travel abroad without an official identification document?
In US we mostly stay in country for vacation basically us going state to state is like Europeans going country to country but odviously to go state to state no passport needed like I'm 31 never had one
should I be worried about automation and potentially losing my job?
Yes and no. It depends on what you do. Really low level jobs where customer service isn't anything important like fast food or groceries then yeah goodbye. Mid level IT at good company then yes it's going away. IT at shitty company. Nope. They can't get their shit together and won't for a long time. Companies that barely function aren't going to make the leap. They're gonna suck for decades. Most people making these predictions work with Google and Amazon so assume other places are similar. They're not. Most places are jobs programs for shitty stupid people and those people are going to fight tooth and nail to keep the company shitty so they have a job. You hear people say job security. Yeah that's for shit tier employees. Eventually sure but we're talking 50 plus years.
How do Christians combat the argument that there are hundreds of gods that exist and are worshipped in the world so how do they know they are worshipping the right god?
Christians don't believe in a huge pantheon of gods. We believe there is only one God. Any other gods in the world are either created by man, or are demons masquerading as gods in an attempt to draw people away from the one true God. It is written in the book of Genesis that, in the beginning, God created everything. In the next book, Exodus, we have the ten commandments. The first commandment of God is that man should not worship any other gods. Since God doesn't want us worshiping any other god but Him, He wouldn't have created other gods.Jesus lived out a full human life, thirty three years long, as a working class person and was finally tortured to death. When he rose from the dead a new era of human history began where people no longer had to rely on living a moral life in order to enter the afterlife. In "The Golden Bough," James Frazer first asserted that this was a common myth among many religions. This assertion has since been [challenged.] They cite historical accounts of people having super natural experience while following Christ. Also the historical evidence such as the dead sea scrolls and Josephus and the prophecies regarding Christ and how he diedMy wife and I are from opposite sides of the world and have two completely different religions. We both have the same God and our marriage was blessed by both religions.
Why do some militaries require men to be clean shaven?
I think part of it may be from tradition, at this point. Not the main reason, of course, but Alexander the Great had his men shave, so that they couldn't be grabbed by their beards. I know a lot of military customs are pretty traditional, so that may be a small part of it.
How is it possible to write code for a computer?
store value in memory", etc This set of commands is what's known as the "Instruction Set". "Machine language" is comprised of lists of these commands and the input values that you want the programs to work on. Since the instruction set is made of very simple commands, programs written in machine language is very tedious to work with and most humans tend to avoid it whenever possible. That's why some really smart people like Grace Hopper worked to invent high-level program languages. High-level languages let you write programs in a simpler, easier-to-understand way than trying to code directly in machine language. As you correctly pointed out, computer's can't really "understand" these languages directly. They have to be translated in to a language that the computer understands, ie the machine language that is hardwired in to the chip. Different programming languages have different ways of achieving this: many use "compilers", many use "interpreters", etc. But it all boils down to the same thing: Programs have to be run through a "translator" program of some sort in order for the computer to understand itthe computer will have different levels of understanding. The first computers quite literally had to be told what to do with 1s and 0s. then we built a layer on top of that which would create 1s and 0s from some more complex language. Another layer, another layer. The ideal is to be able to talk to a computer in normal language and have the various layers translate that down into the 1s and 0s that the hardware of the computer really knows how to deal with.The answer is that the CPU has some hardcoded functionality which can 'read' a specific type of machine language. Instructions that the computer should execute are eventually translated to machine language , and the [control unit] is hardcoded to be able to decode and act upon these specific combinations of binary digits.
why don't taxi drivers just become Uber drivers?
Conversely, why don't Uber drivers just become taxi drivers and stop screwing people, out of their jobs?
Why do Muslim women not think of themselves as 'oppressed?'
I've heard it explained like this: in the same way we may feel oppressed by how our society requires us to hold a full time job or more, we also feel putting up with it to survive makes us strong. I'm not sure how accurate that is because I am not Muslim, and I'm sure the following isn't the case for everyone, but it was explained once to me by a Muslim that complying to all those rules is a test and symbol of strength.
Why do cigarette smokers, love smoking?
Because cigarettes are addictive and things that are addictive are enjoyable because they're addictive. An addictive substance wouldn't be very addictive if it made people hate doing it. It changes your brain chemistry.Primarily because it makes the smoker feel good. Nicotine stimulates pleasure centers in the brain. This is the reason why, like most physically addictive substances, that it is so addictive.Once you are addicted, at least for me, it's not that smoking is enjoyable, it's that abstaining from smoking is misery.
How do apps like Instagram and Vine make money without ads?
they don't they just hope to get bought out that's the problem with most of today's apps -- people just push 'em out and hope they'll get bought out, which is down right silly.So much speculation and misinformation in this thread. What the fuck happened to this subreddit?
Why do we wake up to alarms even if we seem oblivious to background noise while asleep?
While we sleep, our brain recognizes sounds, but doesn't process them because it's already doing something else. In particular, if the sound is prolonged in time , as long as the sound is somewhat regular, our brain ignores them, letting us sleep. When, in our sleep, we listen to a strong sound , we wake up because our brain recognized that something near happened, and it needs to see what happened. Also, in the case of the alarm, soon the brain link the sound to the action 'wake up', so we wake up knowing what disturbed your sleep.
how do we use the pi symbol which represents an infinite number to find the area of a circle which is definite?
Question was already answered elsewhere, but this might be relevant in answering why it's perfectly okay to round pi up to the nearest ten thousandth or so. > **Motivations for computing π** > > As mathematicians discovered new algorithms, and computers became available, the number of known decimal digits of π increased dramatically. > > For most numerical calculations involving π, a handful of digits provide sufficient precision. According to Jörg Arndt and Christoph Haenel, thirty-nine digits are sufficient to perform most cosmological calculations, because that is the accuracy necessary to calculate the volume of the known universe with a precision of one atom.
What's the evolutionary advantage to having muscles capable of forcing your skeletal structure to the point of injury?
> everyone would stop obviously I.e. it doesn't actually represent a disadvantage. Non-disadvantageous things are not necessarily selected out , natural selection does not result in organisms that are necessarily optimal, merely sufficient.Oftentimes injury is preferable to death. While it's not something that you would want to do on a regular basis, the ability to flex, stretch or pull a little extra can mean the difference between losing a fight with a predator and escaping. Or to not be permanently trapped if something falls on you and traps a limb. In fact, more extreme examples of "self-injury" exist in nature. The gecko can shed and regrow its tail as a way to escape a predator. The controls that need to be there are there, namely, the ability to feel pain. It's nature's pop-up box that asks "Are you sure? " before you injure yourself. That's enough to prevent most accidental self-injury on its own, no need to enforce a hard limit that could prove fatal in life-threatening situations. Note: Yes, I know I'm anthropomorphizing the process of natural selection by giving it some form of self-awareness. It is not an attempt on my part to endorse or support the idea of intelligent design. It's merely a metaphorical device to help me illustrate my point.Better alive than injured. If you need to fight off a random tiger trying to eat you, your body goes all Kaio-ken and accesses that extra strength at your own risk. This allows you to pummel the shit out of that tiger or at least get to a safe place. However, when you're not in adrenaline-powered overdrive mode, your brain stops you from using that much force.
Why does the tail rotor on a helicopter spin on an axis perpendicular to the main rotor on top of the helicopter?
It pushes against the spin caused by the main rotor. It can slow down or speed up / change pitch to allow the helicopter to turn. Chinooks fro example don't have them because their rotors spin in opposing directions to counter each other. Also on a side not some helicopters use rotating jets. _URL_2_
Why did Americans invent the verb 'to burglarise' when the word burglar is already derived from the verb 'to burgle'
ELI5: Why do people think America shouldn't be able to have their own language? We're our own unique country, all countries should be able to be 100% autonomous in areas such as language. Just because it was derived from English doesn't mean it has to be the same. Official U.K. English isn't the same as it was hundreds of years ago, why is it surprising that it doesn't evolve exactly the same?", 'Should I Google or make a thread to try to trash Americans for karma? OP, probably', "Language isn't something that's constructed, but something that evolves naturally over time. It all doesn't have to make sense.I like how this thread has more explanations of why your loaded question is incorrect than attempts at a responseWhy did British invent the verb 'to pressurise\' when the word pressure is already the origin of the verb 'to pressure\'? "An innocent man was pressured into confessing that he had burglarized the house." Brits would say he was "pressurised" into confessing that he had "burgled" the house, which makes it sound like they ran a steamroller over him, or dropped a cartoon anvil on him like Wile E. Coyote. And "burgle" sounds like the love child of "bungle" and "gurgle"I used to rage against "utilize" because there's "use" until I found out that utilize implies using something to gain something else from it, such as an alchemist utilizes lead to make gold. I still think most folks I know use that word wrongly. Edit: couldn't grammar this morningThis seems more like a shower thought than something you really need explained to you.

Why do we need to file taxes?
When you earn money from a regular paycheck, an **estimate** of the tax you owe is withheld. Your tax return is where you go through the accounting of how much tax you actually owe, you compare it to the estimate that was withheld, and you settle up the difference . Why might the estimate of taxes you owe be inaccurate? Well, the first is, you can change the estimate. You can tell your company how much to withhold on your behalf. The second reason is, not all your income comes from your regular paycheck. Some people don't draw paychecks. Other people get paid cash. Other people have lots of investment income, or other types of income. Some people get big bonuses at the end of the year that they didn't predict. And the third reason is that the tax you owe isn't just based on your income, it's also based on other life circumstances like: * education costs * medical costs * how many kids you have * whether or not you have a mortgage and how much you pay * whether you had investment losses in previous years and hundreds of other things.
Why are so many people allergic to soy and peanuts, but no other legumes?
Note: Don't know why peanuts are more severe but people are also typically allergic to the others to a lesser degree if they are severely allergic to peanuts.Actually when you are allergic to soy or peanuts you also tend to be allergic to the other types of legumesBecause other legumes aren't fashionable. "My son has Great Northern allergies." It just doesn't really work, does it?
Why do some Asians only want crisp/new money bills?
My boss is Korean, and was mortified to find out I crammed my cash into a coin purse. The way he explained it was that you have to respect money. Don't fold it unnecessarily, face the bills in the same direction, trade old dirty bills for new ones. He says if you respect money it will respect you . He says it's definitely a cultural thing.
The US is over 18 trillion dollars in debt, why are we considered a wealthy, stable country? And why aren't more people freaking out about our debt?
What matters is debt vs the size of the economy, with GDP as a strong indicator of the nation's ability to raise tax revenue if necessary. Further, we cannot straight-up default, because we can always print more dollars. Lastly, if the budget is balanced, you don't even need to pay down the debt, just outgrow it. Real growth and inflation both lower the ratio of debt.
How and why do shows like "Rick and Morty" use a different director for every episode while maintaining stylistic consistency?
I just discovered Rick and Morty yesterday for the first time, I already binged watch 11 episodes, totally looking forward to season 2. I saw it on tv for 20 seconds once and dismissed it as a children’s cartoon, las night I discovered it's not for the kids. Great funny show, hope there are many seasons to come.
How is the age of very old trees determined without cutting them?
Carbon dating is used as well. I looked it up after someone posted the world's oldest trees.
Why can't you parallel park going forward?
Because of the turning method used in vehicles where only the front wheels turn side to side. Parallel parking going forward won't work because there is nothing to swing the non-pivoting rear wheels in to place. Relatedly, this is the same reason it's easier to back a pickup truck into a parking spot. It's also why forklifts have their pivoting wheels in the rear.
Now that the "Freedom Act" has failed to pass, what does that mean for the Patriot Act?
Until my generation starts out voting thier grandparents not much will change. One thing that will hopefully help is the integration of Internet to third world countries. Most of the world doesn't know how the world works quite yet. Once the people who are willing to take a stand against tyranny have access to what we have, there will be no more passive stand by attitudes.
If humans are 80% water, why are we classified as carbon-based?
Carbon forms the basis of most of the complex chemistry that makes us alive. The water is what's known as a 'suspension medium', that is to say, it's just an inert substance that dissolves the carbon chemicals so that they can freely mix and react with each other. It's a bit like saying that a car is a 'gasoline-based vehicle' even though most of it is metal and not gasoline.I just came here to say a mosh pit is only 20% away from being a swimming pool ..think about it lol
What causes us to wake up on our own?
When sleeping your brain is at rest, sort of recharging your batteries. When those are full, you wake up. Typically, if you wake up on your own power and it wasn't from a noise, touch or anything third party. You waking up when your in a light sleep and your body is rested enough. Think of it as the opposite of getting tired. Your body just doesn't need to sleep anymore!
Why Finland wants to introduce Basic Income?
Because we're getting really good at making things that aren't human do our jobs for us and so now we have a surplus of humans who have nothing to do.
Scientifically, what is the difference between color film and black/white film? What changed and allowed film to be in color?
Sensitizers. That's what changed. Photographic film is basically a kind of silver salt that breaks apart when it is exposed to light. But it only does that when it is exposed to blue-violet light. This is why reds and green appear dark in old black and white photographs. At some point , it was figured out some aniline dyes reacted to green light. So that adding aniline dyes to the film would allow you to take a picture of the greens. And then the same thing happened with red when it was found out the cholorohylls would do the same for red. Eventually these sensitizers were replaced by better chemicals. But since you could now take pictures of blues, greens, reds you could compose them into color photographs.
Why some people can fall sleep mere seconds after laying down while I and many others need 20-30 minutes
The biggest contributor to being able to sleep easily, I've found, is being tired when you go to bed. If you sat on your couch or in a task chair all day, and watched Netflix, for 18 hours, you don't need sleep just because it's 18 hours later, and it's not going to come easily. Do something physical during the day to wear yourself out, and do something mental as well. Work out, and read an article on particle physics . Clean out your closets, and work on learning French. Walk around the block while listening to a podcast about the first world war. You don't have to be exhausted, but being at least tired when you go to bed is necessary for easy sleep. Otherwise, you fall into the shitty cycle of no sleep, wake up tired, don't want to do anything all day long so you don't, no sleep, etc. Nothing will break that faster than being active.
Why does the Federal Reserve raise or lower interest rates, wouldn't it be better to just keep it low to help grow the economy?
By 'grow' the economy, you mean have lending and investing going so fast that economic bubbles form from too much access to easy money. This is exactly what causes economic meltdowns when prices start rising faster than the economy can handle and eventually some big player tried to sell and everyone else does too. Thus, resulting in a massive bust that crashes the economy for everyone. Too much growth leads to overvalued stuff that eventually leads to a bust. This is what happens when money is too available .like in the early 2000s when taxes were cut and government spending vastly increased eventually resulting in a housing 'bubble' of prices that crashed the whole economy.
EIL5 why SOPA is even being considered (I'm I Brit)
Running for congress takes a lot of money, and writing laws takes a lot of time, so members of congress just let lobbyists and the companies who hire them write the laws. Then the companies who hire the lobbyists donate money to their congressional campaigns! That's double plus good because they get money and time. Then they can spend their extra time trying to get money from other people to get elected again.People like to think it's all political, but it's a lot about lawmakers trying to find a way to enforce copyrights on the internet a little more effectively. The internet kind of destroyed a lot of creative industries by completely invalidating the legitimacy of copyrights.

how do fleas and ticks survive in fields or yards that don't seem to get much animal traffic?
It seems like many non-mammalian and especially insects and spiders can go without eating. One thought: If you have an exoskeleton as opposed to skin, you are less subject to the effects of the environment. Skin would get worn away, attacked by bacteria and thus require maintenance. But if you are a flea with a hard exoskeleton, what is happening that requires food if you don't move at all?
Why is bad eyesight common?
Because we're not wild animals that rely on excellent sight in order to survive long enough to have kids that won't inherit our eyesight problems. Instead we have a social system with roles that allow people with bad eyesight, even to the point of being fully blind, to function rather than get weeded out by predators and stuff. So bad eyesight is common as a result since there was nothing to remove people who have it from the gene pool. There's all sorts of other contributing causes though. Some of us spend too much time inside on computers looking at things that are close to us rather than outside looking at things that are far away, and this can reduce the quality of our eyesight over time. Plus we live fairly long lives and our eyes change near the end of them, giving most of us the inability to read fine print. But a lot of people that might otherwise not have a survival edge if born naked into a wild uncivilized world without a social structure will live their lives just fine in ours, and they're often noticeable because of their corrective glasses.
Why do I see patterns of spots on tinted windows when I where polarized sunglasses?
You're looking at glass that's polarized through glasses that are also polarized. If you take the glasses and rotate them while looking through them, you'll see the pattern change.
What are the effects of the warm fall and winter we are having in North America?
In Vermont, a lot of our ski towns and resorts are losing money as no one wants to book trips and the people who booked from Christmas to New Years week are also getting screwed as there's nothing to ski on.Substantial reduction in demand for heating oil an other energy used to heat homes and businesses.Also with an El Nino , usually a La Nina will follow up so there's that.Rains will probably occur further apart in days from each other and also fall as heavier rainfall events. This could affect things such as drought in some areas, flooding in others, a distribution difference for runoff water, etc.Here in Ak, there is less snow all over and it is significantly warmer than previous years. I have traveled to rural areas in the western parts of Ak, and they just aren't getting any. There is still grass showing in some places . I know last spring, it was tougher for the whalers in Barrow to kill a whale and put it on top of the ice. The ice was thin and kept breaking.It actually directly affects Maple Syrup production. For the maple trees to ooze syrup, we need a constant freezing overnight in fall. Failure to have proper freezing and thawing results in lower maple sap yield.
Why did the United States lose so many aircraft in Vietnam?
Vietnam War came around at a very awkward time in which the balance of the air power was forming around anti-air. America was investing very heavily in VTOL and not so much in jet fighters. Because of this they made for some very easy targets for some very under trained Vietcongs. But they weren't undertrained. China and Russia were sending in training teams to train the Vietcongs to actively resist America and were donating hand held anti-air weapons to them. This made them into merciless helicopter killing machines. However the North Vietnamese didn't have a lot of planes. Maybe the 2500 that got shot down was their whole air force. Vietnam after the war lost monetary support and donations from the Chinese and Russians and had not updated their air force until 2000. Today their air force sits at 500 planes, 75% of them are over 40 years old.Nva barely had any aircraft. US air to air kill ratio was like 15:1 There were a lot of soviet and chinese donated AA missiles and guns, its very easy to defend your homeland Also over half the losses were helicopters. Low to the ground, always in LZ danger zones, easily lost. The us military was much larger at the height of the cold war. Now with todays budget, they try to do more with less The primary killer of aircraft was anti-aircraft fire from the ground. The Vietnamese had a variety of soviet made surface to air missiles. Also back then the US used more and cheaper aircraft, rather than fewer and expensive aircraft.
Is it feasible to build a wall like the US president is suggesting along the Mexican border?
One thing that also needs to be considered is animal habitats and migrations. Animals don't pay attention to national borders so putting up a wall will restrict their movement a lot. I don't know if Trump will care but if the wall were to be built, figuring out how to make sure animals aren't badly affected would certainly add to the complexity.Feasible? Sure. There are approximately 2000 miles of border and currently approximately 700 miles of "wall". What's another 1300 miles with enough resources to pay for and do the work?There was a great post earlier today by a structural engineer that estimated it would need 3x the concrete used to build the Hoover Dam, and 6x the steel required to build an aircraft carrier. Not to mention the labor and overhead costs to build something that is by and large in the middle of the dessert.Feasible yes. That's not the question but whether it's worth the cost. There is already miles of fence and people jump over it and dig under it all the time. Plus there are people going across customs as well as drugs. Drug and human trafficking is a billion dollar industry. A wall won't stop it.
Why do our bodies not see alcoholic (fermented) beverages as "bad" and make us sick like other ailments (e.g. ecoli)
We probably did not, initially. It wasn't until we developed a gene that increased the efficiency of how we metabolize it that we probably REALLY started drinking it. _URL_0_
Why can one of my web browsers take minutes/fail to load a page, but if I copy and paste the link into another one, it will load immediately?
As others have said, it have to do with a thing called cache. Cache is like a *savegame* for the web. It saves pictures, especial typographies, what IP address correspond to hat URIs , etc., in your computer / smart thingy. So, if it's the first time that you visit a page from a browser it loads slower. But sometimes it may also depend on the tolerance to errors in the page code. If the page code has errors on it, it's more or less easy to interpret what was the intention behind the code, but different browsers have different ways of doing it. Normally it only causes the page to not being showed properly, but sometimes it can make appear the page to be blank or make it load slow. The first cause is usually the one to *blame*, but the other one can happen, and sometimes does.
How whiskers help maintain a cat's balance.
Whiskers are very sensitive sensors, nothing more. They help the cat move around when it's hard to see; they touch things.
Why is the Windows Phone so unsuccessful compared to other smartphones?
I'd say, mainly because of the association with Microsoft. Also, questionable design features. And the fact that it doesn't really bring anything new to what is essentally a Google v.s. Apple battlefield at the moment. Yes, I do realise that that is a very general thing to say.
How do they use engines created for FPS games (Unreal, Frostbite) in non-FPS games (Marvel Heroes, Need for Speed)?
To truly explain it like you're five Think of the engine as building toy blocks. You have traditional wood blocks you stack. You have legos, you have k'nex , you have pipe cleaners, or popsicle sticks. All of these are made by different companies. These are the engines. They created and manufactuered them.
