Why do some websites don't open without "www." when most websites don't need that?
|
**Pre-emptive tl;dr: There's no reason that www needs to be part of a domain name, it just exists as convention. Usually they point to the same place as the primary domain, but sometimes not. Sometimes it doesn't exist at all.** Website addresses are basically just a fancy shortcut to an IP address, at first they were just a means for remembering an address more easily . Originally this was mainly for convenience's sake, but since many sites can be running off of one IP they're pretty much a necessity these days as these tell the server what data to load. Anyway, a website address is made of levels, from right to left. So the extension, such a .com/.uk/.be is the top level, with the namespaces controlled by certain companies . Basically whoever owns the level on the right has the right to control what's on the left. When you buy a domain name you are effectively leasing control of the namespace. So if you bought _URL_1_, you're basically signing a contract between yourself and verisign to grant you the right to manage the namespace for _URL_1_ and every level below it. Now, _URL_1_ needs to have a root record, that is the IP address that it is designed to point to. Strictly speaking you don't need more than that, but a lot of people choose to delegate to a subdomain of their root domain, which they're allowed to do as per their agreement with the governing body of the domain. www is simply the most popular of them. There's no reason it needs to exist, and indeed isn't part of the domain name specification, it's just convention. The vast majority of the time this is set to point to the same place as the root domain, but not always.

Why can't we move our toes independently like our fingers?
|
Human here: You can, it's just harder. Your fingers are easier to move because they have 3 bones connecting them to your hand but your foot only has 1. If you try hard enough you can move only 1 toe at a time. At least I can.

What is the financial benefit to EA for not selling games on Steam?
|
Valve takes a ~30% cut of every game sold on Steam. That 30% is a whole lot of money when you're settling millions of every game you put out. It's so much money that the expense of creating and maintaining your own distribution platform STILL saves you money.

Do you need to have some sort of condition for euthanasia/assisted suicide?
|
Well, the laws vary considerably based on where you're planning on doing it.[Here is a page] on various legal requirements for euthanasia in different jurisdictionsIn what country? In my country there is no possible scenario you can be in for it to be legal.

Why do human bodies build up tolerance to alcohol/drugs but not daily medications like antidepressants/cardiac/etc meds?

I can't speak for the other meds, but you absolutely can build up a tolerance to antidepressants and painkillers and the like

We make leather from cows, sheep and pigs. Why not horses?
|
We can. A horsewhipping is not just an expression. The other animals are food animals. While horses are eaten, they were a delicacy for stone age people, horses are not meat animals the way the others are. The other hides are products of food production. Most likely an old horse is an old friend and just buried.

Why is it so much harder to read a phone when someone else is holding it, as opposed to when you are holding it yourself?
|
We can't hold our body completely still. When you're holding the phone yourself, it moves together with your body - your movement is synchronized with the phone's movement. When someone else holds the phone, that's no longer the case - the phone swings together with the other person's body, not with your's.

If 'white' and 'black' are politically correct terms for Caucasian and dark-skinned people, how come using 'yellow' and 'red' to describe Asians and Native Americans is considered offensive?
|
Because black was used less as a derogatory, and more as a descriptor, maybe? For the record, in social activism circles, the politically correct term to use is "people of color", or POC. Not "colored people", but you put the person first with "person of". Yellow and red as descriptors have also been used in more derogatory, objectifying ways than "black" and "white", if I'm right. Feel free to correct me.

Is "quark" really a nonce word?
|
It is a type of cheese, but the name likely comes from Late Middle High German. So it could have been a nonsense word *in English* at the timeELI5 Where the hell does "nonce" come from?Quark, in Germany and other German-speaking places , is like a soft cheese made from curdling milk and straining it. When Joyce used it, he meant the sound a seagull makes, if memory serves. But it was certainly onomatopoeia at best, and nonsense at worst, designed to rhyme with "Muster Mark".

What happens to my iris when my pupil dilates? Where does it go? Does it compress? Is the pupil in front?? I must know!!
|
The pupil is the hole; that's like asking if a donut hole is on the front or the back of the donut. The iris is a muscular ring -- the "donut" -- which just gets "squished" into a thinner ring when the iris dilates, it's still there, it's just smaller, which causes the pupil to get bigger, because it's the hole in the middle.The pupil is a hole in the iris. The pupil doesn't actually do anything, the iris just expands and contracts.

How does your body know the difference between sleeping and napping? (i.e. when you nap, you wake about in a half hour or hour as opposed to a full sleep)
|
Waking up from a short nap or a full night's sleep depends on your body's [sleep cycle] which lasts about 5-6 hours. It takes about 45 min to enter deep sleep, and once you do, you are very likely to stay asleep for the full cycle. However, during the first 10-30 minutes, your body is still transitioning form awake to deep sleep which is why it's easier to wake back up.

why do humans love spicy food
|
The molecule that causes the sensation of spiciness is capsaicin, which binds to the nerves responsible for registering heat and more importantly pain. This causes these nerves to fire, making us feel these sensations. In response to pain, our bodies release endorphins, which help to nullify the pain and create a mildly pleasant feeling. It is likely that we are attracted to spicy foods for this reason, because it creates a mild euphoric sensation as a side effect of the pain. Of course, the pain response can override the numbing effect of the endorphins, so we have a certain threshold of tolerance, which can vary.

How is it that Singapore, UK and the US found Nestle India's noodles safe to eat, but India found the opposite?
|
There's a possibility Nestle manufactures the noodles differently for exporting to countries which are more stringent with their checking. However, there's also the possibility that it was a shakedown by the government, possibly due to some bribe that Nestle refused to pay. That's the sorry state of politics around here.

What's the reason pirates are depicted wearing eyepatches?
|
The fact that some pirates wore eye patches most likely had nothing to do with a missing eye, and everything to do with being able to see—specifically, above decks and below them. Jim Sheedy, a doctor of vision science and director of the Vision Performance Institute at Oregon's Pacific University, told the Wall Street Journal that while the eyes adapt quickly when going from darkness to light, studies have shown that it can take up to 25 minutes for them to adapt when going from bright light to darkness, which "requires the regeneration of photo pigments." Pirates frequently had to move above and below decks, from daylight to near darkness, and Sheedy says the smart ones "wore a patch over one eye to keep it dark-adapted outside." When the pirate went below decks, he could switch the patch to the outdoor eye and see in the darkness easily .Arrrr We Sure? Though there are no first-person sources from history that state this as fact, there's no question that keeping one eye dark-adapted works. MythBusters tested this hypothesis in their pirate special in 2007 and determined that it was plausible . At least one military manual for pilots pointed out that "Even though a bright light may shine in one eye, the other will retain its dark adaptation, if it is protected from the light. This is a useful bit of information, because a flyer can preserve dark adaptation in one eye by simply closing it." Even the FAA recommends that "a pilot should close one eye when using a light to preserve some degree of night vision."

Why are so many freekicks in professional football/soccer shot so badly?
|
Perfection is what they are going for. They are aiming for the very edge of the net, the furthest distance from the goal keeper because anything aimed in the middle of the net is easily going to be blocked. Being just a little bit off will cause their shot to miss the net but missing a little bit the other way is no different, as the shot goes to the goal keeper and is blocked. Same result, no score. A perfect shot is just out of the reach and still inside the net.The margin of error is small, and there are many factors that could impact the execution of the shot. The player has to strike the ball in a certain way to score - the shot has to be powerful enough, aiming for a very small area that isn't covered by the keeper or defernders, and might possibly be trying to impart spin on the ball to curve it into the goal. Acting against that, the ball is a sphere and the foot needs to strike it at a certain position, with a certain part of the shoe, and from a certain angle and force. A slight deviation could cause a huge miss due to the distance to goal and there's various factors in play like the movements of teammates and defenders, perceived pressure on the kicker, the temperature, the type of grass, whether it's raining, noise level in the stadium etc etc.

Why can most people cross their eyes easily, but not point them in opposite directions outward?
|
Because when you cross your eyes, you move your focus points closer together, and that has a function for seeing things close up.Seeing as far as possible will require your eyes to be pointed somewhat straight forward, not outward.The reason we can't move our eyes in different directions like chameleons is that our big open eyes together can detect light from 180 degrees, with focus at 3-5 degrees of angle. Keeping them in sync gives us excellent depth perception, which has helped us hunting and can be found in most major predators.Crossing your eyes is a physiologically normal thing that you train to do from birth. Whenever you look at something up close, your eyes come together slightly. The closer it is to your face, the closer your eyes get. Otherwise, when you looked at something up close, you 'd get double vision. Looking outwards isn't an "in-built" mechanism in our brain so we can't do itYour eyes are built to focus on a single object and then your brain uses the different angles to determine depth. Going cross eyed is just you trying to focus on objects very close to your face.
|
Why is a big screen that is far away more pleasant to watch than a smaller screen closer to your eyes (which covers the same space in your field of view)?
|
Your eyes can tell how far away objects are, especially if they're only a few metres away. This messes up your feeling of immersion so TVs don't feel as realistic as a cinema screen. VR headsets use optics to avoid some of these issues.

Ghost in the Shell - Free Will
|
Well it is perceived on a delay of around 4 or .004 nano seconds for a brains command to be active. For ghost in the shell, she is constantly getting upgrades to help with a sense of phantom limb pain that she has randomly. Due to the fact that she was a fetus at the time of augmentation her brains wiring and impulses grew inline with the augments. But to keep it simple all actions are electric impulses from the brain in their simplest form. Some automated like circulation, some semi like breathing, and some manual like muscle contractions.

single camera vs multi camera setups for filming TV and movies
|
Multi-camera is often used in sitcoms. It's a cheaper way to shoot the show because you have multiple cameras filming things. Single camera is just what it sounds like -- just one camera. If you have a scene where you see three different camera perspectives, that means they re-positioned the camera for each perspective and redid the scene. Single camera results in a better product, because you can adjust the lighting and everything to make each shot look perfect. With multicamera, you have to have the entire set lit up so that it looks adequate for all cameras. So, with single camera you can get a lot more depth and detail in the shots. Of course, single camera takes longer to shoot, and time is money, so it's far more expensive.Good answers from my fellow industry members too! Its all situational. Depends on what you are doing, where, when, time, budget etc. In addition to the other great comments more cameras mean multiple more people usually. And more blocking/complexity of the shot. And more $$$. That said if you are doing a big stunt than you want a lotta cameras so you can get all the angles on the action as you wont get to blow that thing up twice or put people into danger twice. Those are just some more thoughtsA single camera setup means you can only see the action from one point of view. A multi camera setup means the editor can jump at any time from one point of view to another -- typically one camera shows the broader scene, while other cameras show closer shots of specific characters.

Why do I hear so many radio ads for companies hiring truck drivers?
|
It's because truckers spend a lot of time on the radio The marketing ppl did a study and found out that truckers spend a lot of time on the radio so they put their ads targeting truckers on the radio The problem is that truckers don't listen to the radio, the radio they spend so much time on is their CB radios. Since truckers don't listen to the radio that has the ads that target them, they don't get to hear about all the jobs that the marketing ppl are advertising. Because of this mix-up, the jobs don't get filled and the ads keep running. And that is why you hear so many ads for companies hiring truck drivers.I am a truck driver. Most of the ads you hear on the radio for drivers are for Over The Road drivers trying to fill an industry created driver shortage. Its crappy pay, crappy working conditions and generally a crappy life that very few people are willing to even try let alone stick with if they do. Seriously, you try living 24 hours a day 320 days a year in a space 1/3 the size of an average prison cell and you will understand why they have to advertise so much.

Is there a condition that causes temporary super normal hearing?
|
Any particular triggers? I get something like that occasionally, but usually in a situation like being in a very quiet house and trying not to wake people upThat sounds like a [migraine] which can sometimes cause [over-sensitivity to sound]. Some people never develop the headache which is typically associated with migraines, but do suffer some of the other effects like seeing auras, nausea, vomiting, and sensitivity to light, sound, and smell. In my family, a "minor" migraine is nothing more than seeing an [Indian quilt pattern] overlaying part of the vision of one eyeCheck out a condition called hyperacusis. I have these episodes of hearing amplified frequencies. Soft things become loud. Small noises are irritating. I ask everyone to stop shouting. I can even hear the movement of the joints of my body being conducted back to my ear. A related condition that my mom has can cause it: superior canal dehiscence syndrome.It never occurred to me that this doesn't happen to other people. I'm a little freaked out now. Ill be confronting my husband about this in the morning. I never worried about it because I thought this was a normal thing that happened to everyone.

This may have been asked before but: How do radio waves travel in space?
|
So if you think of sound traveling, it is using some kind of medium or material. It moves the molecules and they hit each other. When you hear something it is actually the pressure of the air changing minutely.In space, however, sound cannot travel. This may be where you get caught up. Light, however, travels very nicely. Light is made up of it's own "stuff" and does not need to make waves out of other material. The "stuff" is subatomic particles which can be both considered a wave and particle . Radio is actually light. The light we see is visual light, but radio is just a different frequency of light that we cannot see, just like infrared, or microwaves. Our eyes can "see" only a small amount of the whole electromagnetic spectrum that all waves fall under. ** They are made up of their own very small particles that travel at light speed through empty space. EDIT: When you think of an atom, they are made up of lots of pieces. If you change the energy of the atom sometimes those pieces "pop" off. Depending on the energy of these pieces they may be different types of waves. The light from the filament in a light bulb is the tungsten atoms getting "excited" from electricity and heat and popping off subatomic particles at an energy and frequency specific to yellow-ish light.

- Why did a downgrade of the US Gov't lead to more people buying treasury bonds?
|
I posted an answer already, but I forget to explain it like I would to a five year old. Say your friend owns a lemonade stand, and wants to grow. He tells you how at the moment he is making $10/day. He says that if you give him $20, he will make you part owner and give you back $2/month and you don't have to do anything. Sounds pretty good, right? Your parents want to borrow $20 too for 6 months, and they'll give you an extra $1 afterwards. Now you're not sure your friend can keep his promise but you are 99.999% certain your parents will. Anyway, one night you hear your parents talk about how things are a little rough and they need to watch their spending, but they still have their jobs and everything's fine. Your friends say their parents said the same thing. This makes you worry about whether people will be able to buy lemonade, since parents might not be able to and won't be able to give their kids money. You start doubting whether your friend will be able to pay you that $2/month, or anything at all. So, you, not liking to take risks with your $20 it took a year to save, lend it to your parents. Substitute the stock market for your friend, and the government for your parents. That's about as close as I can get.

What are the cultural and social reasons to throw a sexual bachelor/bachelorette party?
|
Bachelor parties date back to ancient Sparta, where where men would eat and drink the night before a friend's wedding. That was all about celebrating the union, saying goodbye to the 'carefree' days before a man took on the responsibility of a family, and swearing allegiance to one another for battle and stuff. I think the same thing still stands today, minus the battle thing, and people celebrate in the same spirit in a lot of different cultures across the world. For most people I think it's about having a good time with friends and celebrating the past before you take a big step into another chapter of your life. Looking back through history, I kind of think it makes sense for bachelor parties to be sexual. For example in the 1800's people often didn't marry for love, but rather for status/power, or because of social pressure. Marriage wasn't always a fun thing for people to do, it was sometimes pretty business-like, and it often meant the couple would take on the responsibility of children, more money with their combined finances, and more influence in their community . All that in mind, it makes sense that bachelor parties have a history of being rowdy and wild. I you're going into a loveless marriage to a woman who's expected to act a certain way, or if you're marrying someone you love but you'll have to uphold a certain social standard, you'd want to have fun before you did so. Again, I guess the same train of thought could be applied today in some cases.

Would an object fully submerged in water be considered wet?
|
This is more of a philosophical question than a chemical one. What makes something "wet"? I 'd say that objects that don't absorb water can't be wet, but surfaces with water on them are wet. So a caught fish can be wet , or a person can be wet, though when we say that we really mean their skin. However, the word loses its meaning when you describe something completely immersed in water. The quality of being submerged takes precedence over being wetThere is such a thing as "wetting" described in science. It refers to how much a liquid will favor being in contact with another substance. Its determined by the amount of energy that the boundary between the two creates as compared to the boundaries with air. Its the difference between when on some surfaces you see water droplets that are very rounded, and on some surfaces you see water spread out readily into less rounded lower spreads. That's the closest you 'd really have of a sort of meaningful answer to things being wet. The reason you don't feel wet when you're underwater is most likely because when you're wet but out of the water, you can feel some evaporative cooling from the water, and because there's a difference between some area's of your skin exposed to air and some not, because the hairs on your body will want to be bound by together by the water and unable to move with the air. If you were fully underwater, the hairs wouldn't be subject to surface tension globbing them together and to your skin. A lot of small sensations that don't figure in without also having air in the mix. But as to what is "wet" well definitions in day to day speech are really just descriptions of how words are used. I 'd say something submerged in water is definitely wet.

Does it take more energy to heat things up or cool them down?
|
Assuming your question implies that heating things is raising them higher than the room temperature and cooling them down is lowering them from the room temperature. The second law of thermodynamics says that you cannot transfer heat from a cooler body to a hotter body without some additional work involved. So if you want to heat a body, you simply supply it with energy, but if you want to cool a body by the same temperature difference as the heated body, you'd have to first create a colder body to which heat could be transferred to and which would require higher energy transfer than in the heating case.

What is the likelihood of a US economic crash and how likely is it?
|
Here's what you have to remember: we have *real* wealth. I don't mean numbers in a computer. I mean real, tangible things: strong houses, excellent roads, high-tech factories. We have a very skilled workforce. We have farms that produce tremendous amounts of food per square foot. We have incredible technology. That's not paper wealth - that's stuff is *real*. That kind of stuff doesn't just vanish. Here's what you have to remember about paper money, bank accounts, government debt, and other numbers in computers: computers can be reset. It's real, physical, tangible wealth that can't be reset. The reason countries like Zimbabwe can't just print new money and start over is that they have no *real* wealth to build on. They don't have a skilled workforce. They don't have good roads. They don't have high-tech factories. They can reset their money, but they can't reset their lack of factories. In the past, many countries have had economic meltdowns. The ones that have real, physical wealth to build on tend to recover quickly. The ones that don't, recover slowly. But the interesting thing is: the fact that everyone knows this makes it that much less likely that we'll have any real meltdown, even a paper one. You see, everyone knows our economy will be fine in the end. So they don't lose faith in our economy or our currency, even when things seem a little rocky. Always remember this about economics: look past the paper money, look past the numbers in computers, and be aware of the real physical, material resources that are moving around. You'll find that many things become clearer.

Why do commercial airlines rarely have accidents whereas private jets and planes are frequently involved in accidents?
|
Because the commercial airlines usually have the stricter training requirements, the higher cutoff point and their pilots fly even more regularly.

What are pressure points? Do they work like they do in movies? Can you really disable someone by tapping or pinching specific places?

Best I can tell they are nerve bundles, and yes you can. Generally, it's not a 'incapacitate' but rather can cause intense pain which most people react to. Some people you, can it fact hit them and they can take the pain.

Why do some drinks need foil seals bellow their caps and others don’t?
|
If you can open the lid/cap and replace it without out someone knowing, it needs a seal underneath. If the lid had a plastic piece that breaks, or you have to rip a wrapping to get to it, it doesn't need a seal underneath. It's all about whether you can detect tampering or not.Drinks with foil seals aren't carbonated. That allows them to be sealed under vacuum after they are made so they do not get contaminated. They go through a "canning" process to make sure they stay fresh on the shelf. Carbonated drinks can't be vacuum sealed.

Why must our vote for president have to be private? Wouldn't E-voting be alot easier if we didn't care who saw?
|
The challenges with e-voting have nothing to do with preserving the secrecy of a voter's choice. Also the reason to protect that secrecy are very important. Being forced to reveal your vote can lead to voter intimidation which is disastrous for democracy. It might seem counter intuitive because so many people openly share their voting choices but just having the choice to keep it a secret is enough to prevent the kind of election rigging that happens all the time in dictatorship countries.
|
Why there's a shadow of heat, but I can't see it with my eyes?
|
The reason you can't see heat is because it is emitted as infrared radiation which has a much higher wavelength than the eye can pick up. The heat waves you see and this shadows are caused by the varying density in the air. Hot air is less dense than cold air. Fact. As light passes through air, we don't see any refraction because the air is the same density. However, when there is a massive variance in density in the air, the light is radically refracted through the less dense parts. This is why the light appears to bend and cause cool shadows.

How do mail-in rebates work?
|
The benefit is the perception of a deal. Only a small percentage of the consumers follow through on. So many times a consumer will purchase something with a mail-in rebate and either be too lazy or forgetful to go through the steps of mailing it in. So, while the company has offered the money back to all, it only has to make good on that for a select few.

When scientist clone animal the clone is fully grown up or is it start as a baby and then grow up?
|
The animal starts as a baby. They aren't cloning the animal in the science fiction sense where they make an exact duplicate at the same age - what they're doing is creating a new animal embryo with the exact same genetic code as the one they're cloning. The result is that when it grows up, it's identical to the first one. Scientists have made embryonic clones of humans, which is to say, an embryo that has the same genetic makeup as an adult human subject, but this was more of a 'proof of concept' - there are no human clones walking around anywhere.The clone is an embryo, it then has to be implanted in a surrogate mother sheep and be born as a baby. The clone is genetically identical to the donor. No, we have not clones humans for legal and moral reasons though it would be possible by the same method.
|
Why does it get harder to remember new things when we get older?
|
It's more about conflicting information than about storage. Using your example, when you use a language 24/7 for 20 years you get used not only to its words, but with its structure. When you try to learn another language, you'll have to devote some time learning to not use what you already know. Things get weirder when you have to flat out un-learn something . I beg you pardon for the sometimes faulty english of a brazillian who seriously needs to sleep.

How do popular highways get backed up even though everyone is going in the same direction?
|
The volume of vehicles is the biggest issue. Only so many cars can travel on a given lane in a given time period before the car spacing is too close for the perceived comfort of the drivers. That gets compounded by lane merges, exits and entrances.The problem isn't the traffic on the highway, it's the traffic entering and leaving the highway. If more traffic is entering than the road can handle, everyone behind the inlet will back up as the forward traffic has to accommodate for the incoming vehicle. If you're near a large city with a major thoroughfare, then you have to consider that the surface roads probably don't have the capacity to handle the exiting traffic. The city is congested with people trying to get to their destinations, and so traffic backs up the exit ramps. The ways we know to deal with congestion is to carpool, live closer to work to minimize your road use, use the zipper method when merging, and self driving cars are more efficient than manually piloted vehicles. But the inherent problems remain, given enough traffic.Just like a water pipe, a highway has a limited flow capacity. The usual constraint is places like exits, mergers and entrances. Each of these cause slowdowns of some sort - e.g. they contain capacity and upstream cars must wait.
|
From a psychological/sociological perspective, why does it bother us so much to be ignored or to feel like someone forgot about us?
|
Humans are by their nature a social animal. We evolved to be clawless, fangless, and not that strong. We are intelligent and work together in a group to cover over our weaknesses. Humans are basically a herd animal, and we derive our security from that herd. From our community, from our friends, being a part of that is something we evolved to do. Being ignored or forgotten threatens our most base and fundamental source of safety. Evolution doesn't know you were going to be able to own a gun, that you would have a house that could keep wolves and cougars out. When man was coming down from the trees it was the complicated language, the coordinated behavior that defended him. Feeling hurt is natures way of saying don't do that thing. Whether it be getting a burn, trying to put weight on a broken leg, or emotional pain that undermines the social cohesion that protects us. Feeling sad is a state of being that makes you less likely to take chances, you're sad when you're forgotten and ignored because you're not as safe as when you have people actively caring about you.

Why do numbers in digital clocks jiggle when we chew something crunchy?
|
The digits are multiplexed. That means that each is driven in turn at high brightness for 1/6 of the time. Then the next one is turned on and so forth. It isn't normally noticed but sudden movement causes the on/off cycles to be noticed as your eyes get a slightly different image position each time. Multiplexing is used to reduce the wiring needed. Without multiplexing, you would need 6x7 or 42 signals to drive the display. . With multiplexing only 6+7 or 13 signals are needed.

Why do Flights from NYC to China go North above Alaska then back down, rather than Bee line to China
|
Because that's the shorter route. Flat maps sometimes don't do a good job of representing a spherical earth, especially at the poles. If you look at a globe, you can easily see that this is true.The earth is a globe, not a flat map. The northerly route is shorter when drawn on a sphereBecause that curve on the map is actually a straight line on the ground. It is called a "Great Circle" route, because it follows one of the straight lines that go all the way around the earth. When you see the direction of those flights, you realise what it means for the earth to be round. If you look at that flight's path on a [Polar Projection] map of the earth, which is a map centered on the north pole instead of the equator, those \'over the pole\' flights make sense. There are two reasons why flights can now take these routes. One is that planes are now reliable enough that the cold over-water routes don't carry too much risk; the other is the end of the cold war means that planes from the west can overfly RussiaRemoved as a repost, though the specific places named are not always the same.

Why does tap water from the kitchen sink taste slightly different than tap water from the bathroom sink, despite having the same source?
|
First step is a blind taste test to see if the effect is real or only in your head. Get someone to fill two glasses, one filled from each source. Then see if you can identify which glass was from which source. If there is an effect, repeat it at other people's houses to make sure that it isnt your house's pipes specifically.It depends how much each faucet is used. The one that gets the most use will collect more build up on the other side of the little screen where the water comes out, which will cause a different taste.

How is this new forged carbon stuff stronger than traditional carbon fiber?
|
Without going and reading about this 'stronger' typically means a specfic type of strength - how hard you have to pull on both ends to tear it. In which case an obvious example is plastic. Plastic polymers look like a heap of tangled worms at an atomic level, and this gives them much more of a specific type of strength than could be obtained by lining them all up. It's also responsible for the ability to bend back into the original strength, and I would suspect this forged carbon also has shape memory. In contrast -edit- graphite is composed of parallel sheets of perfectly aligned carbon atoms and it's very easy to sheer off a chip or cut it in half because the sheets of carbon don't attract each other as much as they attract atoms in the same sheet.

What is the benefit of "pre-purchasing" a game?
|
PC games: if the game is bought on Steam or some other DRM manager, the game is downloaded beforehand and installed, and the game is ready to be played the very minute it is released. Console games: games bought in store have the possibility of being sold out before you have the chance to buy itit, even if you go in on the release date. Youpre-purchased copy is added to the numbers ordered by the store, and your name is written on it, so it is not sold to anyone but you. In reality, and in most cases, the company will order plenty for release. Source - worked for EB Games AU. Never again.Games companies will generally offer a little more for people who pre-purchase. An extra level, or some DLC for free. Occasionally you may get early access , which helps to fix bugs and perhaps change the gameplay to a way that suits you better. Games companies do this to raise funds, which they can use to develop the game . However, the customer runs the risk of the game not being finished, or turning out to be a stinker. And since the game is likely to go on sale within 1-2 years, pre-purchase is quite an expensive thing to do. If you want the game ASAP and will be paying full price when it comes out, regardless of the reviews then pre-purchase may be for you. If you don't mind the risk of the company going bust and your money vanishing.

can current events in Ukraine be considered a genocide?
|
It's not applicable to groups of the same ethnic background, but that's not what Russia alleges. Although Ukranians and Russians are related peoples, they have since diverged into separate ethnic groups. Russia is claiming that the ethnic Russians within Ukraine's borders are being subjected to genocide.

Why do men have nipples
|
Its simple. The default human state is female, so when the fetus is in the womb, it starts developing as if it was a female, and builds nipples. Only later do male hormones kick in and build decidedly male structures. There is no real evolutionary advantage to NOT having nipples, and they don't cost that much to build, so natural selection has not selected against men having them.

why do churches and cathedrals need buttresses but not skyscrapers?
|
Cathedrals are made out of stone, so it isn't easily self-supported. The wall can't support much more than the weight of the wall. Also, the walls are individual stones that are loosely mortared together . The extreme weight of the roofs pushes outward against the walls, rather than straight down. Without a buttress roughly in-line with the force, the walls would fall apart. With skyscrapers, the support beams is most of the weight of the building. They don't have to do more than support themselves, and provide more support per pound. They have no roofs to speak of, so the weight is straight down. They also have deep foundations and support pylons to distribute the weight into the ground, which have the same function as flying buttresses, but in-line is into the ground. edit: As ZarathustraEck phrased better than I did, a cathedral is wide open, with a roof. A skyscraper is a lattice of supports all the way through it. A better modern analogy would be a stadium, which often do have buttresses .

How can an electron emit x-rays?
|
Electrons orbit the nucleus of atoms, they can change how far their orbit is, but they need to change how fast they are going. To slow down and get closer, they need to get rid of energy. When they get rid that energy, the energy leaves in the form of a photon . The energy put into the photon defines if its a radio wave, light wave, X-ray etc. . The reason it will move down is if the election is in an excited state, which happens when the atom absorbed a energy from a photon or a collision with another atom .

Why do most cakes and dessert recipes call for eggs?
|
In a cake, eggs act as a leavening agent, thus making cake light and fluffy. In baked foods like cookies, muffins, etc, eggs add moisture and act as a binder. I don't eat eggs, so I always look for the eggless version of things. There are substitutes for eggs depending on what you are baking.When a cake bakes, what's happening is that you're turning a liquid into a foam solid. Two things have to happen. The liquid has to solidify and as that happens it has to form gas bubbles to form the foam pockets. In baking, living yeast is where the gas bubbles come from. Yeast is a mold of fungus that is added as a power of tiny seeds. Yeast are more active at higher temperatures and the yeast eats sugar and exhales carbon dioxide gas just like humans do. This adds bubbles so the liquid is more like soda now. But you still need it to become a solid. Egg is made of proteins that stick to water, oil, flour - basically everything in the cake - but that also "crosslink" or "thermoset" . Just like it does when frying an egg in a pan. Egg cooks to a solid the same way that many plastics do. The molecular chains in the carbon molecules reach across to their neighbors and form permanent new molecular bonds - making one giant molecule. This solidifies the cake while sticking to the flour parts. This is why you can't unbake a cake any more than you can melt vulcanized rubberAccording to [this site], eggs add structure to baked goods, act as a leavening agent, provide richness and affect the color.

How does scam message stay open?
|
When you click the red X, you ask the program politely to close. It's supposed to be used so programs can clean up after themselves and save your work before they quit. Poorly behaved programs, like the scam messages, can just not close down when they receive the polite request. When you use "end task" through task manager , your computer stops asking nicely. It just kicks it out the door and throws whatever the program was working on in the trash, which is why that will always work.

How can movies be remastered into HD when they were originally recorded in standard definition?
|
All "old" films are still saved on their original film reels. Film is actually extremely high quality and still better resolution than any current digital resolution. The original reels are scanned into computer files at a high resolution, nowadays probably at 4k , and the entire movie goes through the post-production process again using current techniques. Things like scratch removal , color correction, visual effects, etc. Stuff that just wasn't available 20+ years ago. This gives the movie that modern look that we all are used to.They weren't. They were recorded on film. Yarr, ye forgot yer searchin' duties, for twas asked by those what came before ye!]

Why do most foods taste completely different when hot or cold?
|
1/2 of the time we eat, what we smell usually helps us define what we taste. If the food is hot, naturally it’s scent would be more present opposed to being cold. Try pinching your nose when you eat. Not the same exact effect but close. Also, you know. Your brain and shitSame reason when you heat something up it feels different, pizza for example gets all floppy and wet, you are melting all the greases and sugars in the food changing the composition of the food.

Are organs the same size for everyone or are they bigger for naturally bigger people and vise versa?
|
While there is some amount of variance, the average dimensions and weight of organs are the same throughout all of humanity according to a rough *height* metric. A 6\'5" adult male would have about 30% larger lung size than a 5\'10 adult male, assuming all other factors are "average". Fatter people will have heavier organs due to fat deposits, but the overall size of the organs won't change based on their current weight. A 5\'10" fat person will have the same rough size/shape organs as a 5\'10" anorexic, just with extra fatOf course, Organs needs to grow proportionately to the size of the person so they may function properly. A good example is the heart. The heart from a small person may not function properly on the body of someone with a bigger build, due to how hard it needs to work in order to circulate blood around the bigger body.

Why haven't we evolved to require less sleep?
|
Because that isn't how evolution works. Something we don't need anymore doesn't just go away as soon as we don't need it. Something better needs to come along to replace it. The people able to function on less work may be more successful in life, but it doesn't necessarily mean they will be able to reproduce better or more.

What actually is snot (nose mucus)?
|
Your body is only really capable of producing a few substances, in different quantities so things like mucus, wax, sweat, semen, saliva, or milk tend to be made up of varying concentrations of salts, sugars, proteins, antibodies, other cells, and water. Now, *mucus* is produced by special cells in your body . It is mainly a mixture of water and glycoproteins . These mixtures also have salts that make it unfavorable for bacteria/fungi to grow, enzymes designed to eat away at viruses/bacteria/fungi, antibodies, and some other immune-related proteins. So mucus is basically a sticky solution created by cells as a part of the immune system to protect you from bacteria and viruses and coats sensitive areas of the body, like the throat, nose, lungs, vagina, etc, etc. Naturally, the respiratory system need a lot of mucus because it has to deal with the most outside invaders all the bacteria and fungi that you inhale. When the cells in your body realize that you've gotten sick, they produce more mucus to expel the invaders of your body you end up coughing up lung mucus and dripping nose mucus because your body is removing bacteria to make you healthy again and prevent you from getting more sick. **TL;DR If bacteria was in an adventure story, mucus would be a cross between quicksand and a piranha pit not only is there no escape, but you get eaten while you're trying.**

Debt as the dollar inflates/deflates
|
> Making another extreme assumption; this does not affect the economy significantly You can't do that, sorry. Such a marked deflation in the dollar would destroy the economy, pretty much a law of nature on that, which is kind of a failsafe in and of itself. The [1923 "hyperinflation" in Germany] is an example where hyperinflation was so bad they had to completely reset the system and never really paid off their incurred debt. So your thought experiment kinda fails at this point. Even a gentler deflation of the dollar's value would have direct repercussions on the other measures within the economy. Inflation caused by erosion of purchasing power, is tied to interest rates for any securities you're trying to sell or renew as part of the next budget's borrowing or as part of refinancing existing debt that's expiring. You can't look at these things one at a time, unfortunately. What countries can and do though is focus more on avoiding deficits and paying off debt when interest rates are high, in the same way you try to time mortgage renewals at your house for when interest rates are low, and pay off your mortgage faster when interest rates are going to be high.

Why words stop looking like words after you type them repeatedly.
|
_URL_0_From what I can tell, your brain recognizes the same word over and over again and gets bored.I would have thought it would have been the opposite to what these other redditors said: I think it's over-focussing rather than getting bored and moving on. Because the connection between a set of symbols and the semantic meaning is arbitrary, the more you focus on this set of physical lines and curves, the more you notice how random those symbols look. Whereas when you're reading relatively quickly, your brain short-circuits through to just grabbing the actual meaning of the symbols rather than getting bogged down in them", 'bowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowlbowl', "/r/answers gives you answers to questions, ELI5 explains those answers in a way that is easier to understand.

If it takes 3 hours for the sun to set in NY to LA, why doesn't the line of shadow move at 1000 mph?
|
I think you might be asking about the [**Solar Terminator**] which does move across the Earth at about 1000 MPH, but due to the scattering of light in our atmosphere the terminator line is not clearly visible on the surface of the Earth.The terminator does indeed travel at 100s of miles per hour ; you would be able to see this more clearly if the Earth was a perfect sphere. To give a specific example, if you were in NYC and decided to travel westward so that the sun stayed in the same position in the sky , you would need to move at about 800mph. You may be confusing the planet's shadow with the shadows cast by other objects . Those shadows would not be moving at such high speed.

What is deconstructive criticism and it's role in group assessments?
|
It is when you just say things like "That's stupid and you're shit at everything" and it totally hurts morale and discourages peopleIt isn't the opposite of "constructive criticism". Rather, it's criticism which is done using the framework of post-structuralist theory. That is to say : it is the analysis of a given work in which the analyst attempts to explore/explain its meaning as it relates to the texts/culture that surrounds it. To "deconstruct" a text is to pick apart not only its meaning, but also the means through which it conveys that meaning. I have no idea how this relates to group assessments though, because fuck those.

If the same animal with different fur color is considered a different species, why aren't humans classified as different species based on hair color or other varying traits?
|
Physical features have nothing to do with being a species. Being a part of the same species is defined as being able to breed and produce offspring that can then produce more offspringThe same animal with a different fur color is not a different species. It is just different colored. All cats are from the same species regardless of what color they are. Two animals are considered different species if they are unable to produce offspring that are fertile.

How is it possible to track down the owners of illegal websites?

Unless they mess up and do something silly and self identifying. That's especially easy if the FBI or whoever can compel the hosting service to give them access to the server and plant some things to try and weasel identifying information out of the connection. Even with TOR you have to take a lot of additional steps to ensure anonymity.

How is point Nemo, a sea point which is the farthest from any land mass, calculated?
|
Here is how I would do it manually: For a start, much of the sea can be dismissed as a matter of course. E.g. the entire Mediterranean Sea is nearer to land than a point in the middle of the Atlantic Ocean. The next step would be to take a compass set at some set range and draw outlines from prominent points - Western Australia or Hawaii for example. Point Nemo must be outside these lines. By increasing this in steps, the area where point Nemo can be decreases. Eventually you get down to a single point. You would need to use a globe for this method due to the inaccuracies in flat projections.With proper maps this problem is trivial. Could you clarify what you mean? With a computer you could step through the map and measure the distance from each point to the nearest land, keeping track of the current farthest distance/point. It's a search-for-max problem. I'm sure there's a clever algorithm that could speed up the search, but ultimately it'll rely on the quality of the maps. If the maps are wrong, finding point Nemo would be very difficult.

Why do cabbage leaves grow rolled up in a ball where they're guaranteed not to get any sunlight?

Cabbage are artificially selected and bred. The wild cabbage leaves are not not balled up like that. In fact the cabbage is the same plant as broccoli and cauliflower.
|
How are dogs bred for specific purposes?
|
Over generations breeders select for traits that make the dog better suited to a certain task. Your dog won't inherently know how to "rat", but will probably enjoy chasing small critters and he/she is physically suited to digging and pushing into small crevices/tunnels in which rodents may liveDogs have a lot of natural instincts, the strength of which vary from individual to individual. By selective breeding dogs with stronger instincts, you basically get a dog with OCD for chasing prey. Combine this with breeding for a size that makes it small enough to chase rats where they might hide, and big enough to kill a rat, and you have a breed well suited for ratting.

Physiologically speaking, why do certain people react differently to marijuana?
|
There is *only* science to this, in fact. There are a few active components in marijuana. First is cannibinol, which produces the "stoned" effect: it is the depressant. THC is the most notable component. THC gets you \'high\'. It has a mild stimulative effect, and in large doses, hallucinatory effects. There are different types of tolerance; dispositional tolerance , dynamic tolerance , and behavioral tolerance . All of these three factors combine in complex and constantly evolving ways to produce your reaction to a drug. Others can be more susceptible either to cannibinol, or THC, or both. Your brain has receptors for both of these . The more *sites* you have, the more *effective* the drug will be, in general. It is possible you have very *few* cannibinol receptors, and a relatively *high* number of THC receptors. If this were the case, you would get almost none of the "depressant/relaxing" effects, and too much of the "stimulant" effects. The stimulating / hallucinatory effect of THC, when it hits too strong and too fast, can bring on that "paranoid" factor. The strain of marijuana you take also has an effect. Different strains have different relative levels and concentrations of active components, and therfore, give you different "highs".

How does Candy Crush recommend your next move?
|
This is haRd to answer because I don't have source code for it, but my guess is it does not know what is coming and it determines the "best" move by looking at all available legal moves and picking one by some method ', "Candy crush isn't recommending a best move per se, the game knows what shapes are on the board and likely just looks for the first potential one it finds. The game drops candies semi randomly based on difficulty. Most games like this have a ratio or chance of dropping something, as well as a maximum number any item that can appear, and then roll the dice, the game knows what's going to fall after calculating it right before the drop down animation

How do you get a second job? Are you supposed to keep the first one a secret?
|
When you got your first job, did they give you a time table on when you are available? You can usually change it . For the second job schedule time around the first job No not at all. You just go apply. You tell the second job that you are currently employed and where, and try to set your schedule around that. Of course if your jobs frequently collide then you will likely have to quit or be fired from one.

How did early humans develop opposable thumbs?
|
Evolution does not work that way. It isn't as if some creature is sitting around thinking "this mutation woukd really help us" and suddenly his kids develop the mutation. The mutation occurred randomly and the environment was so that he survived while his non-opposable thumbed brethren did not. This meant he passed on his genes **THAT OCCURED RANDOMLY**', "Even the earliest humans already had opposable thumbs. That particular mutation occurred far earlier in our ancestry. That said, the mutation occurred randomly, as did all evolutionary mutations. It's not that the environment warranted the need for opposable thumbs, it happened by accident, and those with the thumbs happened to survive, while those without died out, or evolved into other species.

How can acid eat through metal, but not a glass/plastic cup?
|
I'm not sure about the exact solution they are using, but I'm going to use aqua regia as an example. Solid metals are composed of metallic atoms arranged in a metallic lattice, with metallic bonds connecting them NOT chemical bonds. These are much weaker and can be sheared with less energy. Gold, as we know, is very unreactive to most things . However, aqua regia is a special mixture that produces extremely reactive atomic oxygen. This mixture reacts with the gold and forms chloroauric acid that is soluble in water. On the other hand, glass is a very stable material and tightly bonded, which prevents most chemicals from breaking the bonds inside it and causing cracking. One exception is hydrofluoric acid, which is used to etch glass and must be stored in even more unreactive polymeric containers, like polyethenes and such.In that gif it is not an actual acid being used, if you watch the video it explains it is actually mountain dew, its just that the spoon is made of a gallium-aluminium alloy which effectively disintegrates in the water

the use and purpose of pointers in C.
|
The name is more helpful than people realize if you try to think of it visually. It's literally a variable that POINTS to something. So let's say we're playing hide and seek. John is hiding under a box. Sally saw John go hiding under there. Now I walk into the room trying to find John. I find Sally and say "Sally, give me the location of John". Sally is our pointer. I don't want to know about the object John , I want to know about the **LOCATION** of John. So Sally, being kind of a bitch , points to the box, saying "He's under the box, at that location". Now, we have John's location. Now let's say we want to actually look at John and find out what color shirt he's wearing. This is where we **DEREFERENCE** the pointer . We goes to the location of John and looks at the value there . So if we had an int pointer int *c, and we say int a = & c, that means a now has the VALUE of whatever was stored in memory at the address stored in c. Sorry if that's not more clear. Pointers can be tricky to understand, but they can be very useful in some situations. Academia is a great example, as you'll often be asked to implement your own versions of common data types in order to gain a deep understanding of how they work There has never been a more appropriate time to post a link to Pointer Fun with Binky: _URL_0_

What is an itch, why does it bother us, and how does scratching it make it go away / feel better?
|
Scratching an itch, releases endorphins instantly into the surround nervous system area. It provides instant gratification but ultimately makes the itch worse. Like smoking crack and getting an instant high but then coming down. I actually have no idea what I'm saying.Skin is usually itchy because of a foreign irritant. Our skin sends signals to our brain that it is irritated by the foreign object, so we feel an impulse to scratch off that object. This is a useful defense for small insects, or anything potentially dangerous to the body.

Why SSD is better than Hard Drive?
|
For one, they're faster. *Much* faster. Insanely faster. It's not even close. If you were to compare it to running, it'd be a bicycle vs a car. Additionally, SSDs can be much smaller in size, are more durable, and use less power generally. Much of this is due to physical HDDs' physical limitations. In a HDD, there are actual magnetic disks which must spin for you to read or write data, while SSDs, like their names imply, do not. While this means that, with today's disk technologies, storage space is insanely cheap with HDDs, they lose out in pretty much every other aspect to SSDs.SSDs can read and write faster than hard disk drives. They also have no moving parts, which means they are generally less likely to fail.

In baseball, why do they change out the baseball every time it touches the ground?
|
Balls covered in dirt are harder for the batter to see, which could present a safety issue when dealing with projectiles coming in the vicinity of player's faces at 100 mph. Dirty balls may also move erratically because of the uneven scratches and dirt accumulation on different parts of the ball. Getting rid of baseballs isn't a big deal because the teams need a lot of balls for practicing before games. If a ball's removed from a game for a little bit of dirt, it can then be used during practice, and a new ball can be used during the game.Dirt getting on the ball changes the balance, and it is illegal to do that on purpose. It is the same reason spit balls are banned.

How do animals in eggs know when to hatch?
|
Genetic programming. Remember how you latched onto your mom's boob for your first meal? OF COURSE NOT. But you did, because it was genetically programmed that you had an instinctual latching-on process to get that milk into you . Animals are the same. They bust out of the egg when their genetics tells them it's time to based on their level of development, whether or not they have a yolk sac still attached or they're pretty much 100% complete and ready to go.It is determined based on when the animal is finally hungry because it has no more nutrition left in the egg. The egg provides nutrition for the animal to grow within the egg , and once all of that is gone, the animal is left hungry and wanting more food/protein to keep growing. It is at this time that the animal breaks out of its shell in search of more nutrition :).I think you might have better luck finding the sort of answers you're looking for on /r/askscience :)

What are skin tags and why do we get them?
|
A skin tag is actually a benign tumor that usually forms where skin creases, like the neck or armpit, and sometimes the eyelids. They are almost always harmless. They're very common , and thought to be formed by skin rubbing on skin, but the exact cause is unknown. They're safe to leave and safe to have removed - they don't grow back. Be sure to consult a dermatologist for advice.

What is "Salisbury Steak" made from? And is it just a US commercially made food or does hit actually have roots in England?
|
Its roots are in the USA, not the UK. It's named after Dr. Salisbury who invented it in the 1800s. It's mostly ground beef but may contain some pork depending on who makes it. [Details.] There is a similar food in the UK, called a *grillsteak.*", 'I actually live in the medieval town of Salisbury England. You know the one with the Cathedral and the Stone Age henge and all that. Salisbury steak definitely has nothing to do with here.

How come standard pixel widths (360p, 720p, 1080p...) correspond to the number of degrees in a/several full rotation(s) ?
|
It's the beauty of maths. The two aren't related besides the fact they both divide down really well. 360 divides by 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15 etc. As a percentage of these lower numbers that's way more than almost any other It's just simply that because they divide and multiply together so well they are so easy to use. Say you want to double a resolution at 360, well that's easy for any number. But say you want to shrink it to 75% size, or any other fraction . Works super!

Google's new parent company Alphabet?
|
In short, Google had become a huge sprawling company made of a bunch of brands, and Alphabet allowed to separate all those brands and make them independent from one another, while still having the same people in charge at the top. Google has grown to a point where they are no longer just an internet tech company. They now provide widely different services, from home automation , to ISP services , biotechnologies , robotics , self-driven cars or R & D . Being a company segmented into so many different divisions can become problematic. So they decided to create Alphabet, a parent company which will own all of those branches and separate them into their own independent brands. Google is therefore just an internet tech company now. This can be practical because some projects that wouldn't really make sense to put under the Google brand won't need to. There won't be Google hospitals, or Google Robots, things that wouldn't really sound in line with a company that brought us a search engine, Youtube and Chrome. This also allows them to make things like Army contracts with one company or major purchases without affecting the other companies. It's also pretty useful to dodge anti-trust investigations, and from an accounting standpoint, several small companies are much easier to manage than a huge one, so there's also an economical advantage. /u/lililililiililililil gave a good ELIDrunk explanation [here], if you prefer analogies.

How do movie makers hire actors to play 'ugly' roles.
|
Many actors of course find it insulting, but work is work, and getting acting work you gotta take what you can get, its hard.The actor might be a little insulted, but unless people are treating you poorly even when not acting, an actor will realize that it's just a role and nothing personal. Any half-decent director/producer doesn't want an angry actor coming back at them with a harassment lawsuit.

Why do download speeds between ISPs vary, even though they use the same phone lines
|
The factors affecting speed are: 1) ADSL: The distance between your home modem and the ISP's "DSLAM" . The shorter the distance, the faster the speed . 2) The brand, model and configuration of the end devices: Different home modems/routers have different limitations, likewise for the ISP's routers. 3) The amount of bandwidth the ISP has purchased from it's "peer" networks and how over subscribed those links are. . 4) Whether or not your ISP strictly applies QoS on your service . This allows them to do things like deploy a 50Mbit capable modem to 3 different homes side by side, and each having a different max speed limitation based on how much they paid. 5) EMI in other words, interference on your phone line will reduce your overall speed. In general it's a fairly complex topic with many variables, but the above are some of the most common reasonsBecause they want you to pay for faster speeds. Its a 100% arbitrary markup to get more money out of you.

Why is everyone criticizing the movie Stonewall?
|
The producer is being criticized for whitewashing the cast of the movie, as well as not putting and transgender people in, or really, any type of person other than a 100% homosexual white man. He claims that "back then" there weren't any transgender people among the population of those who were protesting . He also pointedly left out any POC characters . When people were scrutinizing these things, he backed up his own view, ignoring what all the people were saying to him, and has said that the reason for his whitewashing is because he was trying to make the movie centered around someone who *he* can relate to, and he is nothing more or less than a white homosexual man. He didn't care about the millions, billions of other people who are looking for representation, and with this specific movie being about the movement being the revolutionary period for the gay rights movement, everyone in the LGBT community, *especially* those who are POC, would have expected to have some sort of representation, and rightfully so. So, basically, he is being criticized for erasing the existence of people who really were a part of that history, and for essentially telling his potential audience to fuck off when they voiced that they were unhappy with the lack of equal representation. Which is the most ironic part of this entire thing.

What exactly creates this 'second' tide?
|
Because the moon and the earth aren't pulling each other like tugging a rope. They are falling towards each other but keep missing because they move forwards faster than they fall. The moon isn't just spinning around the earth while the earth stays still. They are orbiting at their center of mass. The center of mass of the earth-moon system happens to be inside the earth so we don't really notice it. Ok so what does this have to do with anything? The water facing the moon is falling towards the moon faster than the water facing the other way. This makes the water on the far side lag behind giving it a bulge on the back as well as the front. So the water on the back end isn't being pulled away from the earth like you might have thought. The earth is moving away from the water before it catches up.

What are chefs talking about when they're talking about acidity and adding it to food, and why does it feel like I can't taste the difference?
|
Acidity has a couple of uses in cooking. For one, acid breaks down other substances, helping to tenderize vegetables or meat for example. It initiates a chemical reaction. This is also the reason it is used on apples and some other cut fruits, because the acid prevents them from turning brown when being exposed to air. Lastly, cooking is about balancing flavors - sweet, salty, sour, and bitter . You can offset an overwhelming flavor or texture by adding acid. You might not taste it and think "hmm, this is acidic", but it provides a more complex flavorIt's not really about the acid . It's about balance. Let's use your apple pie as an example: * Apple, which is usually on the sweeter side when baked.* Baking spices, which are sweet/herbal - nutmeg, clove, sugar, vanilla.* Pie crust, which is egg and flour, rich and more base. So, when you add the "acidity" it balances out all of those flavors, not overwhelms it. Acidity does two things: Makes fruit flavors "pop" or "burst" by enhancing their flavors. Cleanses the pallet from richness.

What exactly makes that knuckle-cracking-sound?
|
When you release pressure on the joint, dissolved gases in the joint fluid expand. Then they immediately dissolve again and what you're hearing is the fluids "slapping" back together. So yeah, it actually is kind of like a bubble "popping."

Why doesn't a garden-hose eventually explode even when the tap is on and the nozzle on the other end is shut-off/closed?
|
Your plumbing supplies water at a certain maximum pressure. That pressure is lower than the pressure required to stretch the hose. So it's less like blowing up a balloon, and more like blowing through a pinched straw. No matter how hard your lungs can blow, the straw's not going to explode.Its simply because the pressure that is supplied in the hose is not high enough to cause an explosion. If it were the pipes inside your house would explode when you had it turned off at the hose connector inside your housePeople generally think of hoses as a constant-flow source, but that is not true. They are a constant-pressure sourceThe hose or pipe is made to withstand a higher pressure than the water is capable of producingThey do. I lost two this way this summer.

Measles have reapeared in the USA because of anti-vaccination movements. Why should I care if I'm vaccinated, aren't I protected from it?
|
1. The vaccine isn't always 100% effective, and it's possible for the vaccine to not work properly for some people. 2. Many people can't be vaccinated , and those at-risk groups rely on everyone else being vaccinated to protect them.

How does the genotyping process that 23andMe use work?
|
Check out Smarter Every Day's video for a behind the scenes at the factory with loads of useful info:_URL_0_", '23andMe uses a type of sequencing called [SNP genotyping] to look for general trends in your genome that indicate genetic history. It relies of the concept of SNPs , which are single positions in the genome that tend to vary between populations. Picture a double-stranded molecule of DNA. Unwind it, and you end up with what basically looks like a ladder. You can then assign every base pair a number, from one to ~6.2 billion, moving from one end of the molecule to another. The very first base is position one, the next is two, and so on. Each position can be one of the four bases . As it turns out, there are certain positions in the genome that stay relatively constant between people that are more evolutionarily similar, and vary between other populations. For example let's say that at the 512,431st position in the genome most people from Eastern Europe have an A, the Middle East have a C, South America a T, and North Africa a G in that position. If I know which of the four bases is in your genome, I can compare it to a library that tells me which populations have that same base pair. Multiply that by ~~thousands~~ of these SNPs throughout the genome and you can get a fairly accurate sense of someone's ancestry without having to sequence and compare the entire genome[SmarterEveryDay did an episode on this] when 23andme wanted to sponsor an episode. TL;DW Genotyping looks for the presence of specific genes using a gene sequence probe. However, genotyping is also dependent on the accuracy and fullness of the non-biological information provided by the respondents.

Can birds fly in a moving car? If so, how?
|
If the acceleration of the car is zero, i.e. it is moving at a constant velocity, you might as well imagine it as being stationary. Think of an airplane cruising at 400 mph, people aren't being flung to the back of it, you can walk around, go to the bathroom, and function as if the plane isn't even moving at all. The key here is the acceleration. If you floor it in a car, you feel yourself pushing into the seat, if you brake, you fall forward. But if you're moving at a constant speed, you don't feel anything. Because the car is sealed, air resistance is not a factor, so a bird could fly just as you and I can walk on a moving train or airplane.

How network bridges work in Windows (not hardware switches)
|
Network bridging turns your computer into a network switch, combining two physical network adapters into one. They share an IP address, but still have separate physical addresses. The computer compiles a list of every MAC address it sees on each physical adapter. When a computer on either segment sends a frame looking for a MAC address on the other segment, the bridging computer receives this frame, forwarding it out the appropriate interface , after which point the destination computer receives and processes the frame accordinglyA network bridge will take two or more networks and bring them together so that you can talk to machines on either network as though it were all one network. The way it does it is by [learning] where the machine you want is and building up a lookup table or IP address and MAC addresses etc. It can do this by broadcasting the packets you need sending to both networks and figuring out where the machine is, OR by looking it up using ARP.

how does chemotherapy work without killing us?
|
Chemotherapy attacks rapidly dividing cells- so you're hoping cancerous cells that are wrecking havoc on your body, but unfortunately this also means it attacks other cells that normals divide rapidly like blood cells and follicle cells, which is why chemo patients often lose their hair and may require blood transfusions. Different classes of chemos attack cells in different ways, which is why some are harder on patients than others. Very simply put, it is a delicate balance between attempting to destroy as many cancer cells as you can without causing so much collateral damage within the patients body that they do actually die.They focus primarily on killing cells that undergo higher rates of division, which cancer cells fall into. Their exact mechanisms can vary, but as a whole they impede cellular division, causing the cancer cells to die when they divide. Unfortunately, a lot of cells in the body under relatively high rates of cellular division as well . For example, the lining of your intestines are shed and regrown every several days, so these cells wind up being destroyed to a small extent as well. This is what causes the intense nausea that most chemo patients experience. Hair follicles are another example of cells that undergo rapid division, and thus die out during chemo. Avoid killing the patient outright is handled by careful administration of the dose. Its why chemotherapy is done over several weeks and at intervals - it gives the cells in the body time enough to recover before being hit again by the chemodrugs. In short, chemotherapy hits the body and cancer cells, but hits the cancer harder. They spread the treatment out over time to avoid overwhelming the healthy cells in your body.

Why does water seem so cold in my mouth while i chew gum?
|
When you have "cool" water in your mouth, it is draining heat out of your body at a certain rate. If you have ice water in your mouth , it is draining heat out of your body much faster. Menthol is an irritant that increases blood flow. More blood flow means a faster exchange of heat. So the cool water is now draining heat out of you much faster, and your brain interprets that as meaning that you 've actually got ice water in your mouth.It works pretty much with anything minty. I don't have any education or research behind it, but what I quickly read from wiki on the factoring ingredient - menthol - it enhances local blood flow and expands vessels for the time it's in effect, but most of all it, by itself, causes a sensation of chill/cold. Add water to the poor tongue and feel a bit similar to if you were to dip your tongue into snow and then take a glass of water. TLDR; Menthol gives a sensation of cold to the area where it affects. E* It's all new information for me as well, so don't quote me on this :P

Why are there jokers in card decks?
|
The joker is still used in games like Canasta, Gin Rummy and Euchre. By removing it, those games would have to change their rules, which would annoy more people than simply leaving the cards in.> The joker did not appear until sometime around the 1860s. At that time, the game of euchre was extremely popular . In euchre, under the British rules, there is a card known as the Imperial Bower that trumps all others. Decks of cards began to include a special Imperial Bower card, and it later morphed into the joker card that we know today. They're still included most likely due to tradition, novelty, and deck padding.

Why do humans crave sugar?
|
Sugar, fats and starches are all high-energy food sources. During most of human evolution, we didn't have consistent access to these foods. Our bodies evolved to crave them so we would seek out energy sources . A few more berries or a handful of legumes gathered could fuel our muscles for a few more hours in a day. Today in our industrialized world, fats, refined sugars and carbs are about the cheapest foods we have access to. Since we still crave them from when they were scarce, we are now faced with the reality of overindulgence in these foods which can lead to obesity and diabetesThe evolutionary aspects for it are obvious, but it should be made clear that liking sugar and having a craving for it are two different things. The pleasure derived from sugar has to do with our sugar-sensing taste buds, which then in turn enter the brain for the experience. The craving of sugar is due to the dopaminergic diffuse upper pathway, which is responsible for all other cravings. Stimulation of this diffuse pathway by means of pleasurable stimuli reinforces the behaviour that led to gaining that stimuli. Because drugs can directly stimulate the dopaminergic system, the behaviour that would be reinforced would be the intake of the drug. But, in normal circumstances as with sugar, we stimulate our dopamine pathway indirectlyWe evolved in a state of near starvation like most animals in the wild. As such we evolved to seek out foods that have the most nutrition for the least amount of effort. Those foods with lots of sugar or fat.We haven't found anything sweet in the natural world that can kill us. Part of the theory is that sensitivity to sweetness helps us identify safe foods.Sugars consists of carbohydrates, which are a stable energy source for, well, everything alive. High sugar means high energy which in turn promotes survival.
