Why is it dangerous for one blood type to be given to another person with a different blood type?
|
You should note that not all blood types are incompatible with different blood types. O- can be given to anyone, but O- can only receive O- blood. AB+ can accept anyone's blood, but can only donate to AB+. [Wikipedia]. Edit: grammar

Why aren't there any conservative news-based comedy shows in the mold of Stewart/Colbert/Oliver?
|
Of course there are. Rush Limbaugh is one of the longest running radio comedians in history. His audience just doesn't get the joke's on them .This is only my opinion but I'm not sure whether something along those lines would be funny; of course, this could be just my own personal biases speaking. Also, a lot of humor is based around mocking things we don't agree with. Conservatism, to me, appears to be a philosophy based on maintaining the status quo, or returning to a bygone age. A lot of what was considered back in the "good ol\' days" would probably make some people, like myself, somewhat uncomfortable. So, a conservative news-based comedy show would probably come off as being mean, nasty and/or racist and just turn a lot of people offThey have tried a few times, it turns out the audience and material just don't work.

Is Jupiter a failed star?
|
It has components needed for a star, but not enough of them. It needs to become bigger in order to shine. You might think of it as a failed star, but I'm not sure it is proper. Stuff does not have ultimate purpose. You could say, that Earth is a failed star, or Moon is a failed planet. It just happens, that Jupiter is big enough, that in comparison, it needs less stuff in order to glow than Earth does.

why is reddit so obsessed with Weird Al?

I'd guess that a lot of redditors grew up in the 80's and 90's when he was huge and it's nice to see a performer from their youth doing well.

What were airports like in the 1990s?
|
The airport experience hasn't changed that much in my opinion, yes security is more intense but other than that it's pretty much the same. We used to have to book flights through travel agents which in hindsight seems silly, but a good agent in those days was like having a good stockbroker or a decent mechanic. Biggest change since the 90's is the rise of the discount airline. They have made air travel affordable for just about anyone and without them I doubt you would see as many young people as well as people from developing nations travelling abroad. There are also entire airport terminals dedicated to these low frills airlines and with them innovations such as machine check-ins, automated bag drop stations and less legroom.

FCC and net neutrality megathread.
|
From what I understand net neutrality was put into place in June of 2015. So if ISPs can now do whatever they want with speeds and packages, why weren't they doing it before net neutrality was in place?", 'Why do ISPs want to repeal net neutrality when they are already able to charge differing price points for internet plans based on internet speeds?', "Is anyone able to admit any benefits from it's repeal? Or are we all just pretending none exist?

Why does the 72 hour hold for a voluntary psychiatric commitment exclude weekends and holidays?
|
Your question has been answered by several other people, but I just wanted to say I'm so sorry your girlfriend is having a hard time. I hope she gets some help, I found that the coping skills I learned there were not too bad. Please make sure to take care of yourself, I'm sure this is hard on you. Forewarning: When she gets out of the inpatient bubble, she will most likely have a little bit of a hard time readjusting to regular life. I found it to be super overwhelming to be in public. If you have any questions, I'd be happy to answer them if I can, I was in a facility for 5 days and I went in on a Thursday night and got caught by the same hold. Both of you are in my thoughts.

Why are antibiotic resistant bacteria such a big deal? Shouldn't the immune system be able to fight bacteria without the aid of antibiotics?
|
The immune system does a good chance of fighting bacteria. The fact that we're not all sick 24/7 is testament to that. But it can't win every war. Just read up on disease in the past. Massive epidemics that wiped out populations. More soldiers dying to infection than gunshots. Smallpox and Polio being rites of passage that many children went through. Just the fact there are so many people alive today is in no small part thanks to antibiotics and modern medicine keeping more children alive to adulthood. Having like a dozen kids used to be common because that's what it took, so many of them died before growing up. Shit was bad, and if an antibiotic-resistant disease went epidemic it could kill lots and *lots* of people. There's even a non-zero chance a strain could mutate to be more deadly and basically end civilization. Even if it doesn't bring us to the edge of extinction, it wouldn't take much to basically shut down society as we know it, bringing in anarchy and annihilating the economy. It's not *quite* the end of the world yet. There are alternative non-antibiotic treatments out there, and generally the most effective methods are preventative rather than treating after the fact. It's a lot harder for bacteria to mutate resistances to soap, alcohol, boiling water, or bleach than it is for them to manage antibiotics. And it's not like we can't make a new antibiotic. But the problem there is how big pharma works. Any new antibiotic made now would be held as a last resort against new resistant strains. That means not many people are using it, and that means not many people are buying it, and that means the pharmaceutical company isn't making much money. So there's very little economic incentive to make new ones, and if we wait to try and make more until after a resistant disease has sprung up, it might be too late.

How do cousins work? Is my dad's uncle's child my first cousin once removed or my second cousin?
|
The easiest way to think about it is based on your grandparents. First cousins share a set of grandparents. Second cousins share a set of great grandparents. Third cousins great great grandparents etc. When your first cousin has a kid the kid is your first cousin once removed. When your first cousin has a grandkid that's your first cousin twice removed. When your second cousin has a kid that's your second cousin once removed. Etc etc So your dad's first cousins are your first cousins once removed.The way I always try to explain it is: first, second, etc. cousins are always of the same generation. The number shows how many generations down you are from the grandparent you both share. The "removal" part comes from an imbalance in the generations -- the number corresponding to how many generations separate you. So, children of first cousins are second cousins, but first cousins once removed to their parents\' cousins.No mention of double first cousins? That's what happens when cousins share both sets of grandparents, as in one pair of siblings reproduce with another pair of siblings.

Why do police use only two types of dogs for their work?
|
As others have pointed out, they use lots of breeds. GSDs and Mals get picked because they're better suited as dual purpose dogs. If your PD has just enough money for one dog, they'll train it to do the two most needed things: patrol and narcotics. While bloodhounds are great at scent detection, they're not awesome at apprehension. GSDs and others are a balance of both needs.

Can you own land on the moon? Could a nation form on Mars?
|
When you buy or sell a piece of land on earth you do so with the permission of someone who has both the willingness and ability to control the land. I.e., the sovereign government. There is no one that has the willingness and ability to control the Moon. Compare the high seas . These are vast wet areas that states either cannot control or have agreed not to claim. The high seas are governed by international agreements not dissimilar from the Outer Space Treaty cited by deep_sea2. If a private person claimed territory on the moon, interested nations on earth would likely say that the claim is invalid because no one can own the moon . From that point any number of situations could play out. At one extreme the private person might be expelled from the moon by force. At the other extreme negotiations might result in the private person being recognized as a lawful occupant or even a sovereign. New countries do emerge and old ones disappear -- though we are used to seeing this occur in relation to territories that are already occupied by people.

How are people able to paint graffiti on hard to reach places like freeway overpasses or the center divide on a busy freeway with no shoulder without getting injured or caught?
|
They use ropes and ladders depending on the spot. Sometimes all it takes is the ability to climb and some balls. Most people have lookouts to spot upcoming cars. Once they see a car coming they hide, unless they don't give a shit.I was at a stop light near a freeway overpass late one night. I saw a car on the freeway quickly pull over to the far right edge, come to a stop, and the front passenger leaned out the window and over the side to spray graffiti on the side of the overpassI have seen a guy with a rope/strap wrapped around him and being lowered by a couple people on the bridge above. They just lowered him down till he got where he wanted I guess and did his thing. I am sure some do get hurt but its not big news if an idiot runs in front of a carFor the high overpass they stand on box trucks. For everything else its all climbing and alot of evading.

How come you can't really taste the food that's in your mouth if you don't breathe through your nose?
|
Because they've discovered that your [sense of smell is tied into your sense of taste]. In the same way that depth perception is an amalgamation of the sensory input from both eyes, our sense of taste is an amalgamation of the input from sensors in our nose and mouth.

How do seemingly uneducated people come up with very complicated recipes of household products to create recreational drugs?
|
Easy: uneducated doesn't mean stupid. Common misconception. Education is just the acquiring of information. College educated people aren't necessarily smarter than non-college educated people. They just haven't gone to classes for 4 years to get a piece of paper. Intelligence is the ability to learn and innovate. A highly motivated junkie may actually be fairly smart. Economic and social issues may be the reason they aren't higher in society.

A 4GB Micro-SD card and a 500GB micro-SD card are the same size physically, but what makes the difference in storage capacity?
|
One way they can do it is to make them all initially for the higher capacity. But when you're dealing with such a microscopic scale, the manufacturing process is not perfect, and parts of the chip will have faults. After the chip is made, they test it and find where the faults are. Any parts which are faulty, the chip is programmed not to use. And the amount that's left determines how much storage you actually have. The few faultless ones will become the highest capacity ones when they go on sale, but most will have faulty sections that aren't used, and will be sold as having a lower capacity that represents the bits which didn't have faults.Think of the plastic card as a case for the actual storage.Then think of your PC with a hard drive in it. If you put more hard drives into it, it gets to have more storage space, but the PC stays the same size.The same way different capacities of SSD work. They have a larger number of transistors in the same area. That's why larger capacities are being developed so quickly and are increasing exponentially and yet are much more expensive than lower capacities.

Why do we wake up from sleep?
|
Sleep is split into stages which come in cycles 1 to 4 and REM . As you fall deeper into sleep you're actually progressing down from stage 1 to 4 which is deep sleep, then you move back up into stage 1 and without waking will enter REM sleep. Dreaming takes place of waking up. This cycling continues but gets shallower as the night progresses and you become easier and easier to wake. So as your sleep becomes very shallow anything will wake you such as the sound of a passing plane.

Pre 9/11 involvement in other countries.
|
I'm not sure exactly how the terrorists behind 9/11 came to despise the US, but I do know somewhat about our involvement in both Iraq and Afghanistan pre 9/11. So the United States had invaded Iraq during the Gulf War in the early 1990s in response to Saddam Hussein threatening to invade Kuwait. It was a short war and was a decisive victory for the US due to the extreme disparity in military technology. Saddam remained in power, however. In the 1970s and 80s the Soviet Union was occupying Afghanistan. The US supplied weapons and other types of support to a group called the Mujahideen to counter the Soviet threat to the area, and essentially fuck their shit up. The Soviets left once their occupation proved futile . Anyhow, I really don't know much about the reason for 9/11, but the US is a huge supporter of Israel, for which there is much hatred by Islamic extremists. Additionally the WTC was bombed I believe in 1993, so there was that happening back then. Wish I could be more helpful but I thought that would shed some light on the question for you.

how the Great Barrier Reef is now considered "dead" and what factors lead to it?
|
Basically, it's made up of thousands of organisms. Each absorb some chemicals and release some others. Pollution has changed the saturation of chemicals, killing some organism and making others thrive waaaay to much. Also, global warming makes enzymes inside of bacteria not work correctly. Which means, bacteria can't eat properly. Also global warming hasn't lead to more uv radiation, which is bad.Tl;dr, pollution", 'Meat demand caused farmers to raise enormous numbers of cattle. That movement created a huge shortage of greenery. Cattle produce vast amounts of methane, that would be converted, biologically, to oxygen if the greenery were not displaced by cattle farms. The excess methane raises the acidity of rain. That rain bleaches the reefs. --- Watch "Racing Extinction" if my answer leaves you wonderingwhat needs to be better explained is if coral is dying due to temperature or water level change, new coral has the ability to survive in a different location that was similar to what the depth/temp was.It's pretty much dead. Although not technically dead, I would argue it's been written off as an inevitability. One would have to rehabilitate the environment and conditions for coral to thrive. Good luck with that.Conventional agriculture methods including plowing, fertilizers, and biocides are the most destructive actions. These can be reversed by installing gabions and on contour swales.

when cooking meat, why is it ok to use the same utensils at the end when the meat is cooked as you used at the start, when the meat is raw?
|
Uhm, usually I change it but sometimes I fortet, I actually never thought this, but I guess the meat it's super controlled and It's not so bad. I like the meat raw when I season the it before cooking it, I do it in the same plate I'm gonna use to serve it. I find it more tasty. I'm not saying it's the right thing to do, but I like it, so I don't care.

Why do some fabrics get softer when they're washed a lot, while others get rougher?
|
Think of the fabric like different types of hair, say your friend has really oily hair and you don't. You wash your hair about every other day, if not 2 days, while your friend has to wash her hair every day. If you guys switched routines, your hair would become dry and brittle from over washing, because you've stripped the oils out of your hair that keep it soft and elastic. Same thing applies to richly colored fabrics/dyed hair. Hope this helps!

When giving an IV or a getting a shot, how does the nurse/doctor know they're in the vein and haven't pushed the needle out of the back of the vein?
|
As a hemophiliac I have been giving myself injections since I was nine. When pushing to the needle your flesh gives a slight resistance. When you hit the vein you feel that resistance change. It's almost like pushing a loose brick out of a wall. This is the best way I can describe it.

Why do airplane engines rev up so fiercely upon landing?
|
Or, if you're talking about an aircraft carrier, the engines revving up so fiercely as soon as the wheels hit is actual forward thrust, which will be very helpful in case you miss the wire that normally stops you. You don't have room on a carrier deck to stop yourself, and by the time you could notice that you missed the wire , you'd likely be too late to recover. So, every time you land you pretend that you're just going to touch down and then take right off again, and consider yourself lucky if you stay down. Source: probably watched some show on PBS 30 years ago.Those are the thrust reversers. On landing, planes almost always deploy the thrust reversers and increase the throttle a bit to slow down the aircraft faster and use up less runway. The reversers are just ducts on the engines that redirect the flow forwards. If you have a window seat near the wing you can usually see them deploy just after touchdown.What's even cooler is standing 50 ft in front of an engine at full power with thrust reversers deployed. Shakes your insides more than standing next to a subwoofer at a concert.There are flaps that can be opened and closed around the engine to reverse the engine thrust. They use this, along with air brakes and brakes on the landing gear, to slow down so they use less runway and reduce wear on the wheelsThis video explains it well in about 5 minutes time _URL_0_ Good channel in general I literally just got off a plane half an hour ago and was wondering this exact thing. Thanks for asking, OP!

How did we get out last names?
|
Why is it so hard .to use the search function..? Started as an occupational thing. You'd have your smiths give metal, tailors making clothes, millers refining grain, mssons refining stone, etc. And it evolved from there. People started having the same surnames so they changed for a more personal professional work became more known, and certain people were more desirable because of their quality. They'd make a name for themselves and use that to set them apart from the rest. It was also common to name yourself after your father. Ie Johnson, Williamson, Peterson, ect Also there was some regional influence. Irish people tend to have an o in their surname. Or the name could tell someone which town they were from there's a lot. For a more detailed history, search your question you'll find literally dozens of answers.

Why do companies often buy other companies for "Undisclosed" amounts while others buy them and openly say what they bought them for?
|
I business you generally do not disclose information that could be used against you. Let's say you own a business apparently worth $10 million, and I buy it from you. If I paid $5 million, people might wonder what's wrong with the company, and shy away. If I paid $15 million, people might wonder what's wrong with my and question my business sense.

Why are Piranhas so aggressive against other creatures, but not against their own?
|
They are generally not all that aggressive, except for when they are very hungry. In fact, during the wet season, they are found to be mostly herbivorous. It's during the dry season, when water level drops and thus cuts off food supplies, that they are mean. Most of their reputation is based on myths and a thing Teddy Roosevelt did where he blocked part of the river where pihrana were for like a week, and then pushed in a cow. They school for the same reason other fish do--for protection from their own predators. The mother of one of my exes used to keep a giant tank of redbelly pirhana. When she had parties, she'd take people's car keys and toss them in the tank so people wouldn't drive drunk. Little did they know she just reached into the tank with her hand to fish them back out. They were well-fed fish, so therefore had no reason to attack her hand, or each other.

how come we did not hear anything about the meteorite before it hit?
|
The particular meteor that came down over Russia today was not very big. Likely only a couple of meters across. Maybe the size of a small car. While that seems like a decent size if you imagine it sitting on the ground next to you, it's pretty insignificant when it's hundreds of thousands of kilometers away, and moving at dozens of kilometers per second. For an interesting point of reference, near-earth asteroid detection programs that are currently being proposed for the near future are generally aiming to identify asteroids that are 100+ meters in size, which is significantly larger than what hit the atmosphere today. If we did detect an asteroid on a collision course with the planet, our options for dealing with it depend on a number of variables, such as its size, its orbit, and how long before it hits the Earth. Assuming that we've got plenty of time before it hits , there are a number of proposed methods of dealing with it, most of which involve altering its path away from the Earth, rather than destroying it. At interplanetary distances, a small change in course today will result in a large change in location a year from now. If we noticed a big asteroid on a course to hit the Earth in just a matter of days, there would probably not much we could do to stop it.

Why are the Republicans winning so many seats (in the both houses)?/ or why are the democrats losing them?
|
Senate seats are up for election every 6 years. All the seats up for grabs today were won when Obama overwhelmingly won his first election, and many Democratic senators rode along on that momentum . 6 years later, that enthusiasm that swept those Senators into power no longer exists to keep them there. Just to opposite in fact. It is highly, highly common for the midterm election in a presidents second term for his party to lose seats in Congress .

Why is gold and silver so valuable when it has very little practical use in everyday life?
|
During the gold rush, gold was essentially money in metal form. The US dollar was backed by gold. Historically, people needed a common medium of exchange . If you were a fisherman, you couldn't carry around a bunch of fish with you wherever you went to trade for other goods. Gold was soft and easy to work with. It was rare enough that people couldn't just take a stroll in the morning and come back with gold, so the supply was pretty stable. It doesn't tarnish, so your gold wouldn't go bad on the shelf. Most importantly, it was the densest metal that was known. This means that it could not be mixed with other metals without being easily detected .

Why Bluetooth is not exceptional in delivering quality music to wireless headphones?
|
audio over bluetooth is just a digital transfer unlike analog p2 audio, bluetooth audio is first encoded and compressed , then transmitted and decompressed on the receiving end there are at least 3 encoding types.. the most common is called SBC. it is as good as a good mp3 file, if it is badly implemented, it will sound bad aptX is a newer codec, but not everyone supports it. it is considered as good as lossless AAC is the same aac codec from mp4 files. even less receivers support it. Apple uses. it is indistinguishable from lossless by most people. so a cheap bt audio headset will sound bad because it's cheap. not because of bluetooth windows bluetooth audio is usually SBC only, unless you installed something different. iOS/macOS bluetooth audio supports SBC/aptX and AAC and sounds really good if you have a good receiver or headset don't know much about android bt audio support

How does "slingshotting" around a planet or star work? It seems like entering the body's gravity well would require you to expend additional energy to escape it again...
|
This thought experiment can be verified by physical experiment. Imagine an empty sink. A round sink with curved walls. The drain is at the bottom in the middle. Roll a ball into the sink. If the ball is rolled slowly it will circle the drain and soon drop into the drain. Roll the ball faster and faster into the sink and soon it will have enough speed to roll around the perimeter and fly back out of the sink. The drain is the star and the ball is the object / planet / whatnot. As the velocity of the object increases, its momentum increases until its energy is sufficient to pull free of the star's gravity.What you say would be true if the planet were stationary. But planets are moving, often very quickly, around their stars. Orbital slingshots transfer some of this velocity from the planet to the spacecraftPhil Plait has a great explanation of the gravity slingshot which helped me to understand it better. _URL_3_

since knowledge can only be past down from generation to generation through communitcation, how does evolution know when it needs to adapt to a change in the environment.
|
It doesn't. Evolution does not work that way. Evolution suggests that, should an environment suddenly change, those who survive and can pass on their genes will make progress. Say for some reason it's evolutionary advantageous for a species to have a long neck, due to all the food only being at the top of tall trees all of a sudden. It won't be that the species will suddenly get long necks, but that those with short necks are less likely to survive and hence less likely to pass on their genes. If more long necks pass on their genes, the gene pool gets more long necks, and hence that trait appears in the species more and more dominantly due to it being inherent to survival. Evolution is not a pre-set path, rather the case that only certain paths continue successfully. The long necks will be more prosperous than the short necks, and eventually all the short necks will die out, not because evolution forewent them, nor because they fell out of favour when finding a mate, but because they starved due to a lack of reachable food before they could mate.

Why do librarians need to have a Masters degree?
|
A librarian needs to have advanced information gathering and organizational skills. You need to know how to research, and how to begin looking for answers to questions you never thought of. You need to know how to organize information so that others can easily access it. There's a lot of esoteric skills that require specialized training.

Why is adding acid to water safer than adding water to acid? Thinking of the rhyme "acid to water just like you oughtta, water to acid you might get blasted".

Because adding one liquid to another can cause it to splash. It's better to be splashed by water with a little acid than acid with a little water.
|
Are power lines dangerous to the touch or do they have to be damaged to be of any danger?
|
Depends on where you are and the type of power line. In virtually all countries, the high voltage distribution lines will be uninsulated, and therefore extremely dangerous to touch - unless by some miracle you managed to grab onto one without being in contact with an earthed or grounded structure, such as the supporting pylon. That's why these lines are positioned high up and have protection to prevent people climbing the pylons. In some areas, you may find insulated low-voltage distribution lines. These will typically be carrying under 1000V rather than in excess of 10000V, and in this instance, it should be safe to touch unless they were damaged. It's not really a good idea to go around grabbing power lines though", 'No. The answer is no. Power lines are never safe to touch. They are like loaded guns. And always need to be treated like they will kill you. However that being said. There are different types of power lines. Some can be touched while live by professionals, but since you are asking this question, the answer is no for you.

why do republicans argue that Obama and liberal policies will destroy the economy when the NASDAQ is just shy of breaking a new record high?
|
Should be noted Obama isn't really a liberal. It's just that conservatives are so far into the crazy right he seems liberal in comparison.the stock market is not a good indicator of economic successFew thoughts; * Many people are aware that the president has limited influence over short term economic cycles and do not judge Presidential success by stock market returns. President George W Bush suffers under the above comparison and President Obama shines due to factors outside their control. Obama looks great by any stock market metric as he took office at the bottom of a recession. * The fixed nature of presidential terms allow for partisans to find data to support their candidate and their position. For example, Nasdaq might be used since it accentuates the Bush negatives and Obama positives more forcefully than the Dow or S & P 500. * A similar question from the other party might ask "why do democrats argue their policies help the middle class when the top 1% has benefited most under an Obama administration as evidenced by the booming stock market and real estate prices?" or "why do democrats claim to support the middle class when inequality continues to increase under Obama?"* Thoughtful GOP critiques deal with Obama's actions which impact economic growth in the medium term or long termThe other thing is no one really understands economic policy timetables. No one knows when a certain economic policy will cause the desired effect. So in theory the NASDAQ drop could have fallen due to Clinton policy and is increasing again due to Bush policy. I am not saying that is what happened, it is just hard to know or determineThe feds, under Obama, instituted "quantitative easing", which dumped tons of money into the stock market, which has artificially inflated it. So, as stated previously, it is not a good indicator of economic success

When/How do 24/7 stores do inventory?
|
I worked at a Walmart. We weren't a 24/7 location but they still had us do inventory during the day. Always a weekday, starting in the morning. When I was produce manager we did a lot of estimating, since our I hand quantities could be crazy. But one inventory the store manager decided we couldn't estimate. My usual 6 hours of inventory became 11. The worst part was I wrote down my estimates as I went and they were usually very close.At one of the biggest price choppers in the chain i used to come in at 8am with 2 other people and count a few different types of things, like coffee and soup. Only one day a week and the nexr week it would change and so on and so onWhere I work inventory is done during the day. And it gets put on shelf slowly early in the morning! However during seasonal its all done at night!One area at a time, it is a constant rolling process. Also, you can take a small yet statistically significant sample i.e. a 34 sample inventory is enough for up to 1000 items.

Why is it acceptable to wait an hour to see a doctor when you have an appointment?

It's not acceptable for doctors who don't see emergent cases. In most instances it's a question of practice management. If you don't like waiting, leave and find a new practice. We did that, and ended up landing at an awesome practice with folks who are not only great doctors, they're never late on appointments. There was nothing wrong with our prior practice; they just didn't care about our time as much as we did.

How do nurses avoid illness when they're so often exposed to contagious viruses?
|
Early on, they don't. They do in fact catch illnesses and bacteria and viruses. Being in a profession that exposes you to either sick people or a population without a great immune system gets you sick early on. Then you build immunity and a stronger system. I work in a school, and while I had a great immune system before coming here, I can easily be around the students and teachers without catching what they have. You won't become perfect, and everyone's different, but your system will at least improve somewhat.

Why chemical weapon is considered a red line and use of conventional weapons isn't?
|
Yes, but there's an international treaty that specifically prohibits the use of ANY chemical weapons, and a govt using it on its own people, is absolutely a red line I believe any civilized nation should have.I guess because in a war, having a severely poisoned soldier that needs long term medical attention is worse than a bullet wounded one or even a dead one. War logic is cruel. The fact that its banned and forbiden makes the other "conventional" weapons that cause the same collateral damage "legal" is terrifying.

When a mammal gives birth to a litter, are all of the offspring "twins" i.e. have identical dna?
|
In animals that give birth to litters, the females release multiple eggs that are each fertilized by individual sperm. Each embryo has it's own unique DNA. There have been cases, however, where there will be two puppies born in the same sac/sharing a placenta. Those would be your 'twins'.

Are our hobbies and interests entirely a result of our upbringing, or are we predisposed to take pleasure from certain things?
|
I read an article about identical twins who were separated at birth. They ended up with the same job with the same facial hair. Kinda neat. I'd look up the story, but I'm at work and I don't want to anyway.I think this is more of a /r/askscience question with emphasis on psychology. Good luck getting your answer!

if Satan punishes bad people, why is he the bad guy?
|
In the Bible it says Satan is a prisoner, not the ruler of Hell. I think that's a misconception.Well, I'm a bit out of touch with the whole "Is Lucifer essentially the same guy as Satan" discussion, but I think according to Christianity they are the same. To bring a little diversity to the answers, I'll include the Islamic perspective. According to Islam, there's no "fallen angel" concept, and according to traditions Satan fell from a position he had earned, which was higher than even the angels, but according to the [50th verse of the 18th chapter] he is a jinn , but because of his disobedience to God he was exposed for his true character and became the "Outcast". Since then he's been trying to tempt humanity into sin, because [he wants to take down as many humans as possible with him]. In the Quran, the [77th verse of the 43rd chapter] says that an angel by the name of Maalik, is the warden of Hell. Azaazil/Iblis/Shaytan/Satan is just another inmate of Hell who disobeyed God out of their own volition.He doesn't punish bad people. He just gets people to have the same prison sentence as him . He was the first one exiled from heaven to be completely cut off from God. He was also a very high ranking Angel meaning he was very powerful. Seeing he was the first and the highest ranking he was the face of the punishment.

why do a lot of people prefer a salary over contracted hourly wage?
|
1) A salary is dependable. It's much less likely than an hourly wage to get cut, and if it does you'll have substantial warning. If you're earning an hourly wage, you could come in tomorrow to find out you're only working half days until further notice. 2) A salary is steady. An hourly wage can change from week to week, depending on number of hours worked. A salary is the same amount each pay period, making planning for future expenses slightly easier. 3) Salary jobs are flexible. If you need to take some time off to take care of a sick kid, having a salary position usually means that you can just make up those hours in the evenings or on a weekend. As long as you're getting the work done, the exact hours you work are less important.

Why do we "freeze" in life-threatening situations? Shouldn't our bodies be doing the exact opposite in those moments?
|
He's not freezing. He's trying to slow down and go in the opposite direction once he noticed the oncoming vehicle. He even manages to take one step backwards

why do ADHD medications have the opposite effect on people who aren't prescribed them?
|
I'm sure it's much more complicated than this but a simplified version is: in a brain with ADHD the part of the brain that's supposed to slow everything down is not functioning up to speed, so other parts of the brain are acting before they can be coordinated Activate that part with a small dose of stimulant and it works up to speed and slows everything down. If that part of the brain is already working well, then you are just taking a stimulant for no reason.

My Drivers license doesn't have a blood type on it, also i'm a donor.
|
As stated by the others, you're unlikely to be given a transfusion in an ambulance, but it should also be added that they can test your blood type pretty much instantaneously. I had mine tested in front of me and it took seconds. So once you've got them to the hospital, you really don't lose much time doing so.

When factories produce things like high amounts of carbon dioxide as a bi-product, why can't we chemistry them back into less harmful chemicals for the environment?
|
> why can't we chemistry them back into less harmful chemicals for the environment? In many cases this is both energetically unfeasible as well as technically difficult to perform. For example consider if you are burning a fossil fuel you are combining oxygen with the carbon of the fuel to release energy. To create bonds with something else is going to require additional energy input which would only release more CO2! Add on to that the difficulty in isolating the CO2 from the emissions of the combustion taking place and the task is borderline impossible.We can, it's just terrifically expensive in terms of both energy and money. Cost is basically the driving factor in every environmental "Why don't we " question.

why shouldn't i have made this post at the gas station from my phone?
|
They don't, there's no recorded case of DOT finding a cell phone to actually cause ignition of gas vapors as the others have stated, but companies don't want to pay for the UL testing to prove every phone they design is safe. Interestingly enough there is currently only one company that makes intrinsically safe iPhone cases as they were the only company to pay to have them tested. Having tested otterbox, LifeProof, and this companies, I can say the phone itself passed the test, the case is just a gimmick that sells for about $600 each. Won't protect from mild wetness, yet it's sealed enough to prevent ignitable gas from getting into it, I don't think so.

My washing machine has 4 sections: Perm Press, Heavy Duty, Knit and Delicate, and Pre-wash. What's the difference?
|
Pre wash is where you soak really dirty/stained clothes. The other settings are all about the level of agitation. Delicate: very little agitation, best used with a cold water washPerm Press: average agitation, warm washHeavy Duty: very vigorous agitation, if using with sheets/towels hot wash is best If you don't have water temp selections too, they should be set to what I've listed anyway. When in doubt, perm press is a good default. Most clothes won't shrink in warm water, and the agitation is enough to get most things clean without damaging them. Since someone else asked, the dryer is similar. Delicate/low has very little heat, though it's still too much heat for most wool and silk--the air fluff setting is better for those if you can't line dry. Medium will work for almost anything, but will take a longer time with dense fabrics that hold a lot of water. For these high heat is the way to go. For optimum efficiency and reduced fire hazard, make sure to empty the lint trap every time!

Is there an advantage to parking diagonally compared to vertically?
|
Diagonally saves more space. In order to back out from a perpendicular parking space you need to leave more room between the rows, so people don't hit each other backing out. Diagonally, your angle of attack is more obtuse, so you need less space between rows.Each method has advantages, and good designers select the most appropriate for the circumstances. In addition to the sight lines that other posters mention, here are the pro and cons of each: 90 degree Parking: Allows for two way traffic in the travel aisles and makes the most efficient use of curb space. Angle Parking: Uses more curbspace, but can be used when the parking lot is narrower. Only allows one-way traffic in the travel aisles.Angled parking usually indicates one way roads or in the case of parking lots facilitates circulation to prevent congestion if the entrance and exit to the lot is designated. This is why you shouldn't back in or park facing out in angled parking because you'll be driving into traffic and usually won't have space to make a U turn.

Why do some towns still use fire whistles to alert emergency workers when we have cellphones, beepers and radios?
|
A complicated solution is not always better than a simple one. Especially if you would have to keep the simple system as backup, anyway. What if there is a major disaster and your primary system is down? Whistles don't go down. Unless they are dirty, dirty whistles.

What computer viruses are and how they work.
|
It is a piece of computer code that tells the computer to 1) copy the code of the virus 2) most probably send it on to as many other computers as possible through various means and possibly 3) perform some other miscellaneous action, perhaps malicious, perhaps only simply annoying. It is really very similar to a biological virus, hence the name. Biological viruses require the host's cellular machinery to replicate, the same is true of a computer.Any program that makes copies of its self without the user knowing is technically a virus. Usually they are meant to do something that would harm the user, like getting his password or deleting his files.Computer bugs only affect people who don't spray the inside of their computer with a bug spray,it works for me every time.

How can the dollar be "too" strong and how does it negatively impact the U.S?
|
Some good answers here but let me boil down the essential symmetry: * A **strong** dollar is good for Americans traveling abroad , and it is good for imports . Top trading partners sorted by imports _URL_1_ * A **weak** dollar is good for the American tourism industry and it is good for exports . Top trading partners sorted by exports _URL_0_ Takeaways: * If you want to make a lot of stuff within the US using mostly in-US resources, or if you work in US tourism, you benefit from a weak dollar. The benefits are significant; a weak dollar means more jobs are available in the US, because more companies will be making stuff and offering services from within the US. With a weak dollar, the customer support you speak to for an American company is that much more likely to be US-based rather than from some overseas country. * If you want to buy a lot of cheap stuff at Walmart or when visiting other countries, you prefer a strong dollar. A strong dollar also means more offshore jobs. You can't have your cake an eat it to. In general the overall economy prefers that the dollar be a little bit/somewhat strong, but not too strong. The dollar is very strong right now and that's an issue for competitiveness.

Why when one sees, or thinks of, something physically painful do they get a sensation in their junk?

You are an empathetic person and for some reason that pain's going straight to your balls. This may be because a kick to the balls is the most painful thing you've experienced.

Why are there so many rectangles all around us?
|
I'd say it is just due to saving space. A rounded doorway is the same as a rectangular doorway, except for all of the extra, useless space it takes up. Oval cabinets are the same as rectangular cabinets, except the opening isn't as forgiving when you try to fit a large toaster oven into it. Straight lines allow for the utilization of space in an efficient way. You can fit a rectangle into almost any shape and it be just as efficient. The straight lines aren't limited to just rectangles, though. Squares get a lot of attention, too.

why do some people sweat substantially quicker/more often than others?
|
Omg this is me at work. Its 70 degrees and I will break out sweating. Our ac broke one time and it got into the high 70s. Having to wear a smock I was sweating like it was a fucking sauna Edit - everyone at work thinks I'm seriously fucked up. Its hard to talk when sweat is running down your face while customers are looking at you. You feel like a fatass or a miserable out of shape person..

Can the FBI continue to investigate the President even if the President does not want that investigation?
|
Technically? No. All Executive power in the U.S. is given to the President, who simply delegates away most of it to the various Federal agencies. This is the concept of the Unitary Executive which became kind of controversial under Bush Jr. However, everyone agrees that the U.S. Constitutionally has a Unitary Executive, there is just some disagreement on what exactly that means. For instance, does Congress actually have Constitutional authority to appoint things like special prosecutors to investigate executive action? My view on the matter is that they actually don't. Congress's power for dealing with possible illegal activity by the President is impeachment. Now, what would happen if the President tried to use that Constitutional power to stop an FBI investigation? Well, I am guessing it would blow up in his face. It would almost certainly lead to impeachment itself. In addition, Congress has long claimed the ability to appoint special prosecutors, even if it probably isn't Constitutional, and the Supreme Court might be leery of messing with that balance if the President ever objected.Whether they can is irrelevant. You can be certain the NSA targets the President for total surveillance to the best of their capabilities. If they get anything, it will be forwarded to the appropriate agencies and departments. In secret, obviously.

Why is there so little religion in China?
|
When the CCP took power, they were militantly atheist. They destroyed a lot of religious establishments, severely restricted religious practice, and encouraged everyone to be atheist. While some people obviously maintained their religious beliefs and traditions, many did not. Also, religiosity is expressed very differently in Taoism and Buddhism than it is in Abrahamic religions. You will obviously find many devout Buddhists and many people who are very dedicated Taoists, but religious beliefs tend to be fairly flexible, syncretic, mixed in with folk beliefs/traditions, and generally more about cultural practices than being a believer in any real doctrine. Then you have the fact that even though since the 1970s the CCP has loosened up a great deal on religion, proselytizing is still strictly prohibited , only a select few strains of religions are approved by the government, and religious activities are closely monitored. This is one reason why there's a lot of unrest in Xinjiang, where much of the population is Muslim , and do not like that the Chinese government restricts religious education, tries to discourage women from wearing hijabs, tries to prevent people from observing Ramadan, makes it really, really hard to open and run mosques, and places a lot of religious leaders under surveillance. TLDR: Religious practices/beliefs were always different from how the West conceives of religious practices/beliefs, and since 1949, there's been a concerted effort by the government to eliminate/discourage religious belief and practice. Source: studied Chinese history, lived in China for a while after college.Communism allows for only one god: the State. Religion was/is ruthlessly repressed by the ChiComs.

Why does it look like car wheels are spinning backwards when the going fast and on film?
|
On film pictures are taken in series which, when viewed, give us an impression of movement. Essentially it is a lot of still-shots in series. What you are asking is an artifact of this process. You take a picture. Object rotates. Take another picture . It all depends on the timing of the camera's shutters. It may seem the spinning object is rotating slowly or standing still or moving backwards. All because of when the camera snaps a new picture.It can occur in real life, its an optical illusion caused by the speed of the wheels and the way your mind can process it.

The point of high fashion
|
Fashion shows like those are not there to show how you are supposed to wear the clothes, it just shows what the designer's visions and inspirations are. You are supposed to take elements from it and make it work for your everyday wardrobe. For example, no one would wear a tull dress with huge holes in them, but I might wear [this dress]. I don't want to dress like a wizard, but I might wear a cape. I don't want a carousel shaped skirt, but I can wear some carnival prints, etc.

why do squirrels and other small animals run across the road in front of cars when they're safe where they were?
|
I've read before that if an animal is crossing or has crossed the road they will run back to the side of the road they came from because they know it is safe. They don't run in the direction they haven't explored yet because there may be unknown dangers they haven't had time to check for yet.

why are most medications ingestion based, when Injection and inhalation both work faster?
|
If you need medication to act really fast, the doctor will not give you a pill! Pills are for medications that you take regularly , or when convenience and ease of use is more important . Sure, I like the pain killer to act quickly, but if it means I have to punch a hole in my skin first, or sit with an inhaler for 5 minutes, I'd rather endure the head ache a while more instead.A whole bunch of reasons -slower and longer release -first pass metabolism -ease of administration -reduce addiction potential

where does fat "go" when we burn it?
|
We exhale it. We literally breath it out. It's a common misconception that we dispose of it by means of excretion. Partly because it seems so ridiculous that we simply just breathe it away.Google " ted talk mathematics of weight loss " for a great demonstration and explanation of how we burn body fat and the byproduct is carbon dioxide which we exhale. We literally breathe out our fatFat is made up of water and co2 all joined together into long chains. When we "burn" fat, we break these chains into water and co2. We then breathe the co2 out and the water is used by our bodies and/or breathed out.

Why do most STDs spread via sexual intercourse and not through other actions like making out?
|
A bunch of STDs only spread through blood & sexual fluids, but not saliva. So most STDs won't be transferred through kissing unless your mouth or lips are bleeding somewhere.
|
Why are hot cola and cold coffee so gross? Why is almost every drink best hot or cold but never room temperature?
|
Nerve receptors are very sensitive to temperature. In case of taste receptor, their activity is altered by temperature, either reduced or increased depending on temp. If I had to guess I think an item like coffee is best served cold or hot or the activation of the bitter taste-receptor won't be suppressed. The phenomenon is simliar to heat/cold receptors in your skin. They only function with a narrowly defined temp band Neither over or under won't activate it.

The missile knows where it is because it knows where it isn't.

Its an odd way of describing a PID controller. Basically the PID controller will use math to smoothly bring an input towards another signal . The size of the difference can be thought of as the missile knowing where it isn't . The strange wording for the video is trying to convey that the values can be positive or negative .

How places like the UK have amazing download speeds but places like the US have very low download speeds.
|
The cable network run by Virgin Media only reaches about [55% of the country]. Mostly in cities and large metropolitan areas. They recently [bought out] a smaller operator, Smallworld Cable. Virgin are the only cable TV and Internet provider in the UK - the two previous operators NTL and Telewest merged and were then bought by Virgin. Most people in the UK get their broadband through their phone line. The national telecoms provider, British Telecom, has been forced by regulators to open up its network to rival providers. They have a subsidiary company called [Openreach] who have to provide access to the network to any ISP. Some ISPs even put their own equipment in the central phone exchanges in towns and cities. The process is called [local loop unbundling]. DSL has been rolled out and improved - initially at 512kbps, then up to 2Mbps, then 8Mbps and now the average top speed is 16Mbps. The next big thing is to roll out 'Fibre' - this will be [fiber to the curb] and runs at up to 80Mbps currently. This is underway now, BT and Openreach are [working with local authorities] to do this. The broadband market is really competitive because of this regulation. The largest ISPs are all competing on home telephone, broadband and TV packages using a variety of technologies. Wireless routers are included when you get a connection, although most ISPs will let you use your own and even list the correct settings on their support pages. The telecoms regulator has protocols in place to ensure you can switch ISPs easily. There have been a lot of threads on broadband in the US on /r/technology recently. Honestly, a lot of us Brits are confused by them because you guys only have one choice of ISP and are getting such low speeds. That's not really the situation we expected in the US, I guess.

How come when you stand up on a train you're completely still, but when you stand on a bus you have to hold on to something to stay upright?

Train tracks are generally much smoother than roads. Trains don't do steep hills or sharp corners, so tracks have only very gradual changes in slope or direction.

How do people at the NYC ball drop go into the pens starting at noon and not leave for beverages or to pee before midnight?
|
I have some friends that are staying there this year during that time, and the restroom breaks are assured by some sort of reservation they have with a local restaurant inside that area. So if they really have to use the bathroom, they use that shortly before they go outside, and they had a reservation to be in the restaurant until about an hour before the ball drops. Or something like that. Maybe they were scammed; I told them not to go because every New York citizen I knew said they stay the hell away from Time Square during New Year's. The web is filled with people telling you not to go, that it's insane. I was in Times Square in October, and it was fucking insane on Friday night. Like being in a mosh pit. And it wasn't even a special day or anything. That store that sold M & Ms? Had rope and stanchions and a security guard. For a fucking M & Ms store. It was guarded like Studio 54 back in the disco era.You know how NYC always smelled awful, urine scent being the primary offensive scent you would smell when entering NYC? Yeah ', "Before it gets too crowded, you can kind of tag team it for a break, with a few people holding your spot while you go to a restroom in a restaurant. Don't drink too much. When it gets crowded you won't be able to get back, so you're going to have to hold it. *Midnight comes earlier than you think.* Afterwards find a side street if you can.

Why has samurai swordfighting (kendo/kenjutsu) consistently survived while European knightly swordfighting has little practitioners?
|
The knightly swords were designed to combat armored opponents on a battlefield. They were poor duelling weapons compared to the rapier. They had long, heavy straight blades to punch through heavy armor . Despite what you might see on TV, the katana was NOT designed to penetrate heavy plate mail. Japanese armor was lighter. You can tell by the fact that the curved blade isn't designed for thrusting which is required to penetrate plate mail. It's designed to do draw cuts, with the blade drawn across the flesh, which is why it's curved. Arab scimitars the same, for the same reason - no heavy armor. However, the katana was effective against unarmored targets, and lightly armored targets. The single edged curved blade is designed to cut unresisting targets, intstead of stabbing through armor like a western straight sword. Knights would often use their armored glove to grab the sword along the blade, and use it like a spear to punch platemail . The ancient rapier survives as the modern sport of fencing and is the more effective weapon against a single opponent, especially unarmored. So the japanes feudal culture of duelling, kept the katana around. In the west, the same culture of duels kept the rapier. Armor became pointless due to guns, and the armor-piercing straight-bladed heavy western swords fell into disuse.

How do I get spam from my own email address?
|
To-address" etc. Spam emailers falsify these data fields to make it appear as though you are emailing yourself . and it avoids spam filters either on your email server/service or in your email client. The servers or "mail relays" that bounce the emails between email servers etc. have no way of knowing the email has a bogus email address in the sender/recipient fields again because sending emails to yourself is a legitimate thing. The only way you can block this type of spam is by blocking the IP addresses of known spammers.

Why are lie detectors used during a police hiring process when they cannot be used in a court of law to determine someone's guilt?
|
A skilled examiner can get quite a bit from a polygraph. When I was at fort Jackson several of us got selected to go to the school where they train federal agents to administer polygraphs. It was pretty interesting. They basically gave is a thumb drive and had us install a virus on a computer. Then hooked us up to a polygraph and had the trainee try to figure out what we did wrong. Everyone who tried any of the bullshit methods of beating the tests would get called out by the main instructor. They may not be able to determine exactly what you did, but they can clearly tell if someone is doing something to be deceptive. If they know you're being deceptive, even if they don't know the reason for it, that's still an issue for concern.

Why is it easier to follow a line when cutting something?
|
I assume it's to do with the fact that you're almost actually inside the material instead of on top of it, meaning there's sort of a guideline, not sure of the physics of it though, even then I can't cut a straight line to save my live but that's just me

How the Western White men who join ISIS do not end up getting their head cut off once they're in ISIS territory?

They sometimes do. But ISIS is more than willing to let these guys fight for them. So they just choose not to cut their heads off. It's not like ISIS has some sort of requirement to cut off the heads of all westerners.

Why is it that I really want to be productive, but my brain literally does everything it can to stop me?
|
I recently found out that I could have ADD . Despite this likely being over-diagnosed everywhere, I believe it, after reading descriptions of living with it. When I'm at work, i really want to get something done, but instead i flip between monitors and windows for hours, trying to settle my mind to work on SOMETHING productive, and just can't. Slightly distracting myself with music often helps, getting some energy out SOMETIMES helps , caffeine actually helps me concentrate quite a bit I dunno. Could be a lot of reasons, and this isn't really an explanation, but it's something to consider.

How does hunting (legally) benefit animals? Particularly those that are endangered?
|
One way is to cut down on mouths to feed. If there are too many of one species in an area with not enough food, if you kill one hungry lion then ten won't starve. That's an oversimplification, but hopefully helps provide a little insight. Also, licence fees can help pay the wages of the gamekeepers. And yes, I think she's a bit of a dick too. And no, I am not an expert, just providing my 2 cents' worth. I do know that you can't just relocate elephants - they will walk back home even if it takes a decade.A big aspect of this is motivation vs perception = reality. Hunters want more of the animals to kill hence more animals are bred for them to kill. Its perceived as wrong since there is a monetary component, even though the result is positive Environmentalists motivation is to keep animals from going extinct but just barely. The more dire the case, the more attention, fame, money their cause will receive. They are perceived as the last protectors of a dying species although in most cases their methodology is ineffective

How do EMPs actually work? I know WHAT they do, I just don’t know HOW they do it.
|
Electromagnetic induction - if a conductor moves through electromagnetic field or the field shifts then an electric current appears in it. At low strength it can be enough to flip a bunch of 0s to 1s in electronics and glitch it out until it's restarted, at higher strengths it can cause permanent damage by overloading some circuits.Can a chicken wire fence be used to wrap electrical stuff to create a Faraday cage to protect the device?

Why is rice so readily available and cheap?
|
-Rice is grown partly in flooded fields. This reduces the need for pest control as most weeds can't grow underwater. -Because of this rice is only hard to grow when first planting; afterwards controlling the flow of the water is all that is really needed. -Rice is harvested multiple times per year. -Rice is very easy to store. -Land and labor are cheap.I feel people in this thread are ignoring the fact that rice commercially grown here in the United States, specifically Arkansas, Texas, Louisiana, Mississippi, Missouri, and California. We use modern farm equipment to harvest rice in fields of giant mono-cultures, just like corn or soy beans. Here is a handy video about how rice is grown in Louisiana: _URL_0_Rice is not low yielding at all. It is one of the most productive crops in the world, able to support high populations like in India, China, and Japan. Also the rice that you buy in America is likely mechanically harvested via machines ', "People we're cultivating rice as early as 3000 BC. It grows well in those climates and can be harvested multiple times per year so it was the ideal crop for East Asian farmers.

If we can store up to 128GB on a micro SD card, why are we still using big bulky hard drives in computers?
|
Micro SD cards aren't built to last very long. They're usually used in a camera or phone; somewhere where you will just want to retrieve files sometimes. The hard drive on your computer is being written to and read from constantly by the operating system. A MicroSD card would fail much faster in this scenario. They're also more expensive per GB than a hard drive. Solid State Drives are gaining popularity, though. They're smaller and faster than hard drives, and they last quite a long time. However, they are also more expensive than Hard Drives or MicroSD cards. Compressing files takes a long time. If you ever try to compress a movie or a large application, it takes quite a while. Compressing and and decompressing files would take a lot of CPU time/cycles, and your computer would run slow. For me at least, I would rather have a fast computer with a little space than a slow computer with a lot of space!", 'Because MicroSD cards cost 5-10x what hard drives do for the same amount of storage.While the largest commercially available Micro SD card is 128 GB, the largest commercially available 3.5'' HDD is more like 4TB, over 32 times larger . and for about 2x the price. So you still get more space for price in HDD over SSD. Compare [128GB microSDs @ Newegg] versus [4TB HDDs @ Newegg] -- *I'm only doing this to illustrate the difference in price per GB, not to advertise for the site*

Why no nuclear *research* subs?
|
Combat subs are built for combat. They're ill suited for research, which itself is a very vague. Research requires specialized hardware designed for the task at hand. That said, everything operates on a finite budget. Nuclear subs are expensive. Why pay 1000x the price of standard equipment to do the exact same job? It just takes money away from other useful work. They have a role and a benefit for military purposes, but that doesn't aid research in the same fashion.The scientific return on the investment of resources for that project would be greater if applied to robotic exploration.

If morphine overdose can be used to euthanize, why can't it be used in death penalty executions?
|
I vote for Nitrogen. It's the way I plan to go. Takes about 1/2 hour and is peaceful. Another option for execution - air bubble? No cost!", 'In Ohio, they use Dilaudid which is about 15x more powerful than morphine.

How does the Earth's rotation effect an Aeroplane in terms of distance travelled?
|
It doesn't affect it because of conservation of momentum. The plane is still moving as fast as the surface of the earth, plus or minus whatever the jets do. So there technically would be a small difference between flying easterly or westerly, but that's insignificant. The earth is about 25000 miles around, so you would have to fly about 1000 mph due west to get rid of that momentum.

Why can't I hear myself snore?

ELI5: Why can **I** hear myself snore? Sometimes when I'm taking a nap I hear my snores and wake up.

Why is it so hard to study 1 hour straight, but you can spend 8 hours gaming or doing sth else with no problem?
|
Because you lack motivation and interest in the subject. As you progress in your studies, you should find yourself passionate about your area of specialty. If you don't, then pick another major. I'm not saying that every assignment will be a joy or that studying will become your favorite pastime. But, if you honestly don't enjoy the subject matter and if it's honestly a chore to study for an hour, then you aren't passionate about the subject. And if this happens with all your classes, then you may have chosen the wrong field to study.
