Why aren't birds electrocuted when they stand on power lines?
|
Electricity wants to take the easiest way to the ground the wires that are used for the power lines have low resistance, meaning it is easy for the electricity to travel through it. whereas a bird has a high resistance so it is hard for the electricity to travel through it. therefore almost all the electricity will travel through the wire, and almost none would go through the bird. If the bird were really long and touched the ground as well as the cable, it would travel through the bird as it is the easiest way for it to get to the ground so the bird would be friedElectricity flows from point a to point b. Very rapidly. For the current to pass through the bird it would had to be touching two wires. Large birds like hawks often **are** electrocuted when they stand on pairs of lines.Because they don't complete a circuit. If they stood on the two bare wires of a single circuit, they might indeed be electrocuted. Standing on one insulated wire is as safe as handling hot Romex.

Why chickens are not protective of their eggs like other birds?
|
I grew up on a small farm. We always had laying hens. So I can tell you from experience that you are mistaken completely. It varies between chicken breeds. Some breeds of chickens are "broody." Meaning they do a good job of laying eggs and taking care of them until they hatch. Broody hens will peck and claw you to the point of drawing blood if you mess with the eggs or chicks. Others are not, because they have been bred to a point where they just don't give a shit. They will lay eggs and ignore them afterwards. We used to use a golf ball to try to encourage hens to lay in a particular spot because they'll think it's another egg and adopt it and lay more. I 've ended up with bloody knuckles checking to see if a hen was laying only to discover she just tried to take on a predator 100X her size to protect a ratty old golf ball. tl;dr: depends on the breed of chicken edit: spelling', "Selective breeding. No one likes trying to collect eggs from a protective chicken. she's better off in the pot than pecking my hands, when her compatriots are just as productive but less likely to attack.

Why is it that each month, our country adds "250,000 jobs", but unemployment seems to remain the same?
|
The real answer is that the official unemployment rate has long been deflated because it doesn't include people who have looked for a job for so long and not had any success that they have given up. Those people are considered to be "not in the work force" and are therefore not "unemployed and looking for a job", which is what the unemployment rate measures. As economic conditions improve and more people find jobs, those people who gave up are reentering the workforce at approximately the same rate, making the unemployment rate change slowly if at allThe population of the US is growing at about 0.7% per year. In 2013, the population increased by 2.3 million people, or just under 200,000 per month. Any number of jobs under 200,000 means there are more new people than jobs, any number over 200,000 means that there are more jobs than people being added. You also have to look at the "Uneployment rate." The rate you usually hear quoted is the [BLS U3] unemployment rate. It only includes people without jobs that have looked for a job in the last four weeks. A lot of people are counted as employed who actually have advanced degrees but are working at Starbucks while they look for a better job. The rate does not count people who have been looking for a job for a long time, but haven't actively for a month , the disabled, etc. As the job market improves, people who were not previously looking for a job get back into the hunt, people quit their two part time jobs to finally get a full time position, etc. Thus, the unemployment rate may stay relatively flat even if a lot of jobs are created. You might also want to check out the [Labor Force Participation Rate], which is the total percentage of people between 16 and 65 who are employed. It's currently 62.6% and falling.

What really happens when you get a blown motor?
|
That could mean a lot of different things. The timing belt could have snapped, causing the pistons to hit the valves. A connecting rod may have broken due to a spun bearing, punching a hole into the block as a result. Blown really just means irreparable damage, but it doesn't tell you what broke. And if it's an older car, a mechanic may also tell you the engine is blown when the damage is technically repairable but it's cheaper to buy get a used a remanufactured one.

Why is it in their nature for some animals to be so loyal and friendly towards humans while other animals despise us and are not friendly or loyal?
|
Generally the animals that are loyal and friendly have been bred and conditioned to be exactly that. Take dogs. We have spend thousands of years breeding them. We have selected certain traits that we enjoyed and bred them for that reason. Loyalty and friendliness were some of those reasons. And it is in the dog's best interest to be friendly too, cause dogs that aren't friendly or trustworthy are generally not fed and even put down. Then we take that natural inclination towards friendliness and loyalty and further compound it by teaching pups from the very start what behaviour we want them to have and what behaviours are bad. However that tiger you meet in the wild? He wasn't bred to be friendly. It isn't in his best interest to be friendly.

How do people become right handed or left handed?
|
I think it's still unknown. Scientists had a theory that it had to do with left or right brain dominance. But now it's pointing more towards genes.It is weird though. I'm right handed with writing, but left handed in sports .I started school ambidextrous, meaning I could write equally well with both hands. I was forced to choose which hand I would write with in 1st grade. I chose right. So now I am right handed.

Why and how does sex appeal change over time?
|
It's a combination of cultural and biological factors. Obviously its typical and instinctual to be attracted to the opposite sex and certain features that indicate health/child-rearing ability and the like. However, if you particularly like something or especially associate it with sex, either accidentally or because society associates them together, then you may find it sexually attractive in a kind of pavlovian way. Heels might be a good example of something a lot of people typically don't find sexy until it's associated with women . Some people with poor social skills may find they don't enjoy humans at all and be sexually attracted to inanimate objects such as cars or trains, because they DO enjoy those things and we're raised to associate pleasure with sexuality -- truly, there are some interesting documentaries out there about people in extreme cases, fucking their cars and the like. People can be attracted to pretty much anything for the vaguest reasons between biological triggers and sexual association and pure chance. It is almost wholly subconscious and out of your control though.

Why does (fire) cooked food taste better than raw food (mostly)?
|
> Is it an evolutionary thing so that we cook our food more? Evolution works in a kind of after the fact way. Those who cooked more survived better and thus reproduced moreThe [Maillard Reaction] occurs when the ~~enzymes~~ amino acids and sugars are "caramelized" which produces that yummy brown goodness. *just found out the reaction is "nonenzymatic"', "I think that you would find [this book] VERY interesting. It's all about the difference between cooked and raw food, and how it affected our evolution. Short answer is that we have evolved to like sweetness, because sweet foods have sugars, which are easy-to-digest energy. And cooking tends to convert different molecules in foods to sugars. There's a lot more to the story though, and I highly recommend that book.* Cooking food actually increases the chemical energy in meat and other foods. High-energy food tastes better . * Cooking food kills off a lot of pathogens, reducing the chance of poisoning. * Cooking renders some inedible foods edible by breaking down indigestible substances.

Why do we only have Black Friday sales once a year? Why can't we have the deals all year long?
|
Some stores tried this. They found that they sell more if they have higher prices then drop them shortly for a sale than if they keep the sale-low prices all year. People just really like sales.

how to birds fly so in sync in a flock?
|
I don't have sources, but I have heard a few explanations. First, they make the decision to move in any one direction based on a sort of democratic system. One bird might tilt its tail or wings a certain way, and that is its 'vote'. When a majority of the birds in the vicinity agree on which direction to move, they all shift in unison. Then, birds further away in the flock have a 'chorus line' reaction. Much like a woman in a chorus line sees a leg kick up down the line and anticipates her own kick, birds see others changing direction and do so in a sort of wave.

why do some cans get cold when shaken.
|
Its not actually getting colder, it just feels like its getting colder. When the can isn't shaken, heat is transferring between the liquid content of the can and your hand by conduction. When you shake the can, the liquid starts moving, and introduces heat transfer by convection. Convection has a much higher rate of heat transfer than conduction, and so when you shake the can you are transferring heat from your hand to the liquid at a much higher rate. This increased rate of heat transfer from your hand to the can is why you feel it getting colder, even though the contents would actually be warming up, because you are performing work on the can and inputting energy into it in the form of heat.

Why do pregnant women with Ebola have a 95% chance of dying, (rather than the 40% chance of dying)?
|
During pregnancy, the immune system is suppressed to prevent the woman from rejecting the fetus. This makes fighting virulent infections a bit difficult. This is also why many women with autoimmune conditions experience remission during pregnancy.
|
What will realistically happen in 20-30 years when the babyboom generation dies and their wealth is inherited/re-distributed?
|
You're making a lot of assumptions not necessarily tied to facts. You're assuming that a decent portion of that 4-10 trillion dollars are liquid assets just sitting in an account somewhere not being spent. A gigantic portion of that is guaranteed to be real estate and property that will simply be passed on as is. In addition, a huge portion of that is going to spent on nursing homes or medical care as they age, so it will go into the economy in a slower rate that way as well. In short, it's not as if there's going to be a 10 trillion dollar tidal wave of cash dropping on the younger generations.
|
Why does warm air rise?
|
Density. Warm air has more energy in each particle which means it expands in volume. Equal mass but a higher volume means lower density. Hence,, they rise. Similarly, cold air has less energy per particle and tend to stick closer to each another. Equal mass with lower volume means high density.

Why do I wake up tired after I've slept in?
|
If you wake up during the wrong stage of sleep you can feel extremely tired. This is why if you get up after your body wakes up normally you usually don't feel too exhasted, but getting woken up from an alarm can leave you devastatingly tired. This is just one possibility though, there are many others.

How will planting a wall of trees across Africa stop the spread of the Sahara desert?
|
One thing that can lead to desertification is the loss of plant roots that hold soil in place and make it better at retaining moisture. Part of the hope is that the trees will help hold and enrich the soil while also providing some measure of wind break to decrease the extent to which to soil is stripped away.
|
Do insects get hot from the sun? If so how do they cool down?
|
insects are cold blooded, so they generally prefer hot environments to colder ones. This is why there's suddenly millions of them around as spring turns into summer, and why most die off or 'hibernate' through the winter. In extreme heat conditions lots of insects have tricks they can use to survive; lots of them become more nocturnal, some can harden their exoskeleton to retain more water, etc.

Why do tennis balls come in a sealed container?
|
The rubber that tennis balls are made of tends to dry out, stiffen, become brittle and less bouncy if they are left out too long. "Fresh" tennis balls bounce better, and are thus preferred for actual tennis play. If you're just buying them to play fetch with your dog it doesn't matter too muchTennis balls are made out of two pieces of synthetic rubber, joined together in the middle with a seam. They are then covered by two pieces of material . Moral of the story is, they leak. They slowly lose pressure over time and become "dead", losing their ability to bounce. Balls are sold in pressurized, not just sealed, containers. I'm sure you 've noticed how hard the container is before it's open, and all the air that squirts out when the seal is broken. Storing the balls under pressure means that they can't leak. The outside pressure is the same as the inside pressure, so everything stays the same. Even if they 've been in the package for years, they're still fresh and bouncy when you take them out. A few days or weeks outside of the package, and they'll lose enough pressure that they clearly don't bounce or feel the same anymore. If you 've watched tennis on TV and saw players bouncing/squeezing balls before they serve and throwing them away, it's because they're testing to ensure they haven't already gone dead, and throwing away those that already have.

Why does breathing stop being a natural thing after we think about it
|
There is a part of our brain that controls heart beat, digestion muscles, everything we can't stop, is controlled by that part of our brain. He also controls blinking, breathing, and all things you don't have to control, but can choose to. Those functions have an override 'switch' that you can pull by thinking about it. This lets you close your eyes when you want to, or hold your breath before going under water. But as soon as we stop thinking about it, it goes right back to automatic.

Why do most people sleep better when it rains / thunderstorms ?
|
I can't say I know for certain, but I'm guessing it has something to do with it being a calming noise to some. Eg. Waves on the ocean, raindrops, piano. I definitely sleep better when it's raining, so there's that.Instinctively we realize that the likelihood of an attack from predators is greatly diminished due to them also seeking shelter from the bad weather, so we subconsciously believe ourselves to be safer and therefore we sleep better Some peoples brain is too active in silence. They use what is referred to as white noise, coined by the noise one would hear on a tv when no signal was received through the antenna and the screen was white and there was a constant noise. The noise can be rain, or a loud fan, or static noise, but it has to be constant and make it hard for your brain to dwell on thoughts. Allowing for the person to reach a more meditation state. Which allows the body to relax, which helps producing melatonin , quick starting sleep cycles.Ive always felt comfortable in secret/secluded/small spaces. When it rains, clouds are closer to the ground, visibility is reduced, and there are generally less people out. Put that all together and when Im lying in bed at night, I feel like I'm in this secret space thats just very peaceful. The sound is very soothing to me as well. And the sound indicates that my favorite weather is happening outside.

How did Mexico defeat France when they were clearly outnumbered?

At the battle of Puebla? The French weren't ready for a fight, and the Mexicans were. They had made much better defensive preparations than the French forces expected, so the French attacked expecting an easy victory and weren't able to react when they met stiff resistance.

The speed of light and relativity
|
I think you are missing a key part of the theorem of relativity here. That is: **the speed of light is the same for ALL observers**. So, no matter how fast you are moving the velocity of light is still *c* . So lets consider your example: > if you had a flashlight and a rock, and the flashlight was moving at 200k kps relative to the rock, and the flashlight was turned on Your conclusion is actually wrong, nobody will observe the light to travel at 100k kps. In this case a person riding on the flash light would see the light traveling away from the flashlight at *c*. A person sitting on the rock would also see light traveling away from the flashlight at *c*. Light travels at the same speed for ALL observers. Now I imagine that you are asking, how can this be??!?! And the answer is where we get into the mindfuck of relativity. For this situation to happen both people must measure light's velocity to be 300,000 *kilometers per second*. This is possible because space and time it relative to each person. 1 second for the person on the flashlight is NOT equal to 1 second for the person on the rock. Also 1 metre as measure by the person on the flashlight is NOT equal to one metre as measured by the person on the rock. Even thought they are moving with respect to each other they both measure 300,000 Kilometers per second, *because time and space is different for each of them*. .. Let that sink in a bit. .. Ok, so to reiterate: time and space are relative to the frame of reference you are in. But the speed of light is constant for all frames of reference. PS. Lastly, in regards to light 'slowing down' this only happens when light travels through a medium, for example air, or glass. But a beam of light traveling through glass has the same velocity *for all observers* no matter how fast they are moving compared to the glass.

How are these new chipped credit/debit cards offering more security when cashiers do not prompt us to enter a PIN, signature, or show ID?
|
While that is the case, most identity theft doesn't happen with your actual card. It happens when they get the card numbers. If you had your actual card stolen, you'd report that as soon as it happened. People using your card numbers isn't noticed until you see it on your bill.The goal of the chip is not to defend against physical theft of the card. That's exactly as much of a vulnerability as magnetic stripes . But it's also not a major type of credit card fraud, because people tend to *notice* when their card is stolen. As soon as it's noticed, they can call the issuer and get it flagged. The point of the chips is to protect against *cloning*. Unlike physical card theft, cloning is a very common type of fraud. A magstripe exposes all the information on it, so someone sticking a skimmer on a card reader can get all the magstripe data . In contrast, a chip has a secret that it never reveals. The payment terminal sends certain data to the chip and gets a response proving that the chip knows its secret, but this response is no good in other transactions . So, you can't clone a chip card.

Why/when did tea begin to lose its popularity in America?
|
Have you never stepped foot in the South? We drink gallons of sweet tea a dayTea is incredibly popular in the US. The standard beverage in the south during lunch or dinner is iced tea and most tend to drink 16-48 oz of it when they have it at a meal. You are correct that hot tea is less popular than coffee is as a hot beverage. Some of this is due to us having more access to coffee than much of Europe after their empires fell, as well as it being a standard part of the rations soldiers got during WWI and WWIISweet tea is a staple in the Southern US. In other parts people love their specialty teas. Tea is still very popular here.

Why doesn't water burn?
|
So, "burning" is combining something with oxygen , such that the final result is more chemically stable than what you started with. Now, I used a lot of potentially confusing terminology there. An oxidizing agent is simply a chemical or element that becomes more stable if it has extra electrons. Think of it as kind of the same as a magnet, which is "more stable" when it's attached to a bunch of metal. If you take a magnet and put it in a pile of iron filings, it'll pick up a bunch of them, but will eventually reach a point where it has so much iron stuck to it that it can't pick up any more. An oxidizing agent is like that, but with electricity instead of magnetism. It greedily accepts electrons . . . up to a point. So now, imagine burning hydrogen. What you're really doing is combining hydrogen with oxygen in the air, which creates a new compound -- water -- that is more stable than either hydrogen or oxygen alone. The oxygen pulls electrons from the hydrogen kind of like a magnet with iron flings, but once it has two electrons , it becomes stable. In fact, water cannot be made any *more* stable by combining it with additional oxygen. If it could, then burning hydrogen would result in the hypothetical, more-stable end product instead of water. **tl;dr:** You can't burn water for the same reason that you can't burn ashes: It's already been burntBurning is the release of energy from combining oxygen with something. Water already has all the oxygen it can handle - you can't "burn" it. If you want to burn something, you can burn hydrogen to -get- waterWater is a product of combustion reactions, not a reactant. Typically, only *organic* compounds can burn .

Why do women enjoy sex even if they don't climax yet men are left relatively unsatisfied when they don't "finish the job"?
|
just think about what's actually necessary in order to reproduce.Armchair evolutionary psychology would suggest for the most part men cannot reproduce unless they climax, while women can, which leads to a greater need to climax in order to feel satisfiedFirst, it's worth mentioning that women find great satisfaction in achieving orgasm. However, when you look at a sex-binary physiology, different bodies respond differently to sex. Specifically in the typical male anatomy, pleasure increases exponentially the closer one comes to orgasm, which often occurs singularly without immediate duplication. A non-orgasmic sexual encounter for a female does not have the same repercussions - she hasn't spent the entire sexual encounter preparing her ovum. Without orgasm, the fluids in a male anatomy become stagnant, and nocturnal emissions may occur to release the buildup. "Wet dreams" might serve a similar purpose to the female menstrual cycle in that sense - disposing of sex cells and other fluids that aren't immensely viable. It should also be noted that "multiple orgasms" are disproportionally observed in women. This has led people to think that a male orgasm holds much more sexual significance than the female orgasm, which can happen more than once in one encounter, and may indicate a reduced intensity through this reasoning. This is just stipulation though.

Why are there no (or few?) green mammals?
|
[From this], it would seem that the reason that there are no naturally green mammals -- I'm not counting sloths, whose green pigmentation comes about from algae in their fur -- is because hair colour is determined by melanin. Melanin doesn't have a green form. In birds and lizards, the skin is capable of [scattering blue light], which leaves a greenish or bluish colour that you don't often see in mammals. Mammals never really benefited from vibrancy of colour in the same way that a lot of species did: to my knowledge there are no poisonous mammals, so that takes out the benefit of being brightly coloured as a warning in the way that tree frogs might be, and they tend not to have quite as much reliance on vivid colour for mating rituals in the way that, say, birds might. From an evolutionary perspective, mammals spent most of their time trying to go unnoticed and keep warm, which lends itself to brown fur. -- mandrills and such -- but they seem to be recent evolutionary branches, at least on a lizard timeframe.)

How do gameshows get the money to just give away day after day?
|
A top network show like *NCIS* is paying about $2 million in episode in actors' salaries alone. A premium cable show like *Game of Thrones* runs $6 million an episode. Games shows are cheap by comparison no actors, no writers, no car chases, just a single set, a washed up actor and a few bimbos. They do it all in one take, and can bang out a week's worth of episodes in an afternoon. If they give out $100,000 in prizes, they are still coming out way ahead.Advertisements. You know how on the price is right you guess the prices of all those products? All those products pay big money to be shown on that showThe same way all TV shows generate revenue. Ads. People pay good money to have their advertisements shown during popular shows. So while nobody would pay to advertise during "Who wants to make $100" 1,000,000 is such a large number that people tune in even though people rarely win much. To compare, at it's peak, several of the actors on Friends were making 6-7 figure salaries PER EPISODE. TV is expensive to make, but it can be very lucrativeLet's take "Who Wants to Be a Millionaire" as an example. The million-dollar prize has only been won 12 times since 1999. Many contestants end up bowing out, and taking only half of what they 've earned, often going home with $10k to $20k. A minute of national advertising time on a syndicated TV show will easily pay for the typical contestant's winnings for that episode.

Why does the body store unnecessary amounts of fat, to the point where humans can become morbidly obese?
|
You have to keep in mind that access to enough food to eat yourself to death is a fairly modern thing to have. Of the billions of years of life evolving that led to us, it's only in the last few thousand or so that this has been possible. If you don't have access to this much food, "storing unnecessary amounts of fat" becomes "being able to eat more now and use it later." Taking that into account, the ability to store dense reserves of energy , which also happens to help keep you warm, is an extremely useful survival tool. In fact, it's postulated that this is one of the evolutionary advances we have over other apes: a gorilla or chimp that massively overate like a person can would just die from it. Being able to "stock up" internally is one of the abilities that allowed our ancestors to migrate through areas that didn't offer enough food. The only other mammals that can put on arbitrary amounts of fat like we can and not die from it are aquatic . Don't get me wrong: all mammals have fat stores, but humans can put on several times our normal weight in fat alone, and most mammals can't do thisBecause our modern eating habits are an extremely recent event, on an evolutionary time-scale. Our bodies are still highly optimised for the eating habits of many thousands of years ago, when food was much scarcer and you were forced to take whatever you could find. This placed a huge evolutionary premium on saving and storing as much surplus energy as you could. Fat provides a very convenient way to store a large amount of surplus energy; each 1g of fat stores around 37kJ. As an aside, this is possibly why we generally view sweet and fatty foods as "tasting nicer". In an era when you didn't always know where your next meal was coming from, there was probably a big advantage in acquiring a preference for foods with a very high calorie content.

How is possible to watch a video file whilst downloading it at the same time?
|
Let's compare this to an highway in a building-process:On the start you've got the informations about the highway like the name and the length .Now the construction workers are getting the plans and the material from somewhere . With this information they build the street kilometer per kilometer . Once one more kilometer is built you can actually drive on it . And because the contruction wrokers also know how long the highway is going to be, they know when to stop. If the company supplying the materials and plans for the highway or the construction workers are too slow, you have to stop at the last finished kilometer . So, it's possible because there's a data stream containing frame per frame. And hence you only need the latest frame and maybe some of the previous ones, you can show the latest fully downloaded frame.

Why sand/salt melts ice?
|
The sand is for traction, not so much to assist in melting. It helps cars grip the ice better. Ice is used because it lowers the freezing point of water. Water normally freezes at 32f, while salted water can stay liquid at 0fSand doesn't *melt* ice, it just provides traction. Salt "melts" ice because it essentially lowers the freezing point of water but it can only do this down to a certain degree If it's too cold out, you 'd have to use something other than salt that can lower the freezing point of water even further.

Beep sound used for censorship
|
It's normally 1k tone, which is a standard for testing audio in broadcast. Basically it's used because broadcasters have always had it available. Many times silence is used, but you notice it less. There may be rules in place that I am not aware of, but generally tone is used when the person's mouth is visible. 'Audio drops' are used when the mouth is not visible. It is possible to adjust the level of the tone to match the dialogue, but it adds another step that no one cares about. _URL_0_ _URL_1_

Magnetic door locks. How do they work?
|
The magnet is a simple electromagnet. There is an iron block welded or bolted to the door on one side, and there's a mounted system with more iron bars on the frame of the door. When it's active, there is electricity going through the part mounted on the frame, which holds that part and the part on the door together. When you can open it, the electricity is off. There's a switch on the inner jambar thingie which allows electricity from a unit that controls the magnet through. The controller senses that the bar has been pressed, and it deactivates the magnet. The same thing happens when you swipe your card or whatever method they have to deactivate it on the other side. In the case of a fire, there's a place on the controller for the fire safety system to be wired in. When the alarm goes off, it is sending electricity to the controller like if someone was pushing the jambar or swiping their card, and it stays disabled until the fire safety system is turned off. Source: I've taken them apart and hacked around with them several times. They're neat.

In the event of mankind being wiped out (nuclear, asteroid, virus, zombies etc) what do the people aboard the ISS (and any manned spacecraft in orbit) do?
|
Die. Nothing else for it, it'll come sooner or later when they run out of the relevant resources needed to live. There wouldn't be any specific plans for the crew to follow, and even if there were everybody on board would know it doesn't matter anymore if there's nothing else to do but choose how they die. There's a firearm kept in the Soyuz capsule in case they land in a remote region after getting off-course. Meant to protect against wildlife that might get over-interested. It'd work just as well if anybody on board wanted to just end their life then and there. You've also got the airlock, of course. If you want to try and wait it out, see if maybe there is some hope sooner or later the atmosphere can't be kept breathable, the ISS relies on resupply ships to bring, among other things, oxygen. Sooner or later the food and water supply will fail. Even if you got over those, somehow, it's just a waiting game against something breaking you can't fix without a specialist and/or parts you don't have.

Why do the Oscars award movies from the previous year?
|
They're held around the end of February. If they held Oscar's 2017, awarding only movies from 2017, they would only have two months of movies to award. Then, when February 2018 came around, they would miss the other 10 months of films of 2017 because they could only focus on films released in 2018 ", 'Oscars should be handed out 5 years later. Avoid the hype, look back at the quality, see what lasts. Avoid any embarassing CRASH scenarios.

If you take a picture of a clock every minute, then show the pictures in rapid succession, it will go from 12:00 to 12:01 to 12:02 and it'll look like it's going forward. If you take a picture of a clock every 23 hours and 59 minutes, then show the pictures in rapid succession, it will go from 12:00 to 11:59 to 11:58 and it'll look like it's going backwards. Motion picture cameras take pictures much faster than once a minute, but the same thing can apply. If the wheel is spinning at a speed where it rotates 90% of the way between frames, it will look like it's spinning backwards.

How did people originally translate languages?
|
By pointing at shit and saying what you called it. It's not a great technique fit explaining ennui, but for something like pig, it works just fine, and to be honest, in the days of 'first' most French people didn't know what ennui was. Once you have the verbal language written is just teaching the person to right like you would a kid.

What is the concept of a nation-state, and how is it different from pre-WW1 concepts of soveirgnty?
|
Before nation states, countries were mostly owned by dynasties and/or aristocrats . Once countries converted into “war machines”, it became a sort of social contract between the state and the people, where the men would be conscripted into the war machine in exchange for a stake in the country’s management in the form of votes. Nation states were a way to give “peasants” or the none-ruling class a stake in the future of the countryThe Treaty of Westphalia in 1648 defined the idea of sovereign state. This kind of state gets to "own" the space between their borders, in exchange for taking responsibility for whatever their citizens do.

Why do people hold their hand on a bible when making an oath? What if the person isn't Christian?
|
The "hand on the bible" gesture is purely symbolic. Meant to express that your words are all honest. If you are not Christian, you can ask for another religious text or governmentally binding, secular text where you will be asked to perform the same gestureThis country has a basis in Christianity, as do many of our laws, values, and legal foundations. Back in the day, you swore an oath to God that you were being honest. You still can, or you can chose to swear to honesty in general without the Bible presentTo add on to previous answers, if I were elected President, I could choose to be sworn in on a copy of the Constitution, which I honestly think should be the default.

Why and how does flour/dust explode?
|
It doesn't really explode, it burns. Explosives turn to gas almost entirely and this *new* gas causes a shockwave as it makes space for itself and pushes air away. Flour/dust burns, because it's dispersed fine particles it causes a huge fireball where entire volume is on fire, heating up the atmosphere air already there and causing it to expand. It burns way better in the air than while piled up, because it's surrounded by lots of air and can burn from any side. So if there's enough combustible dust floating in the air and an ignition source appears it can start a chain reaction where flames and heat from one grain of dust ignite the other particles nearby until the entire dust cloud is on fire.

What do websites have to gain by making their visitors annoyed (from excessive popups/poor formatting/etc) to the point that they leave and never come back?
|
I think you may be talking about a specific type of site. They're not actually trying to provide value and they know you'll never come back. I'll simplify the numbers here but the obtrusive ads and sheer volume of them mean they get paid 2 cents in total for the page view where you saw the ads. They paid 1 cent to get you to view that page . They made 1 cent on your visit. They repeat this a million times and presto, they've got $10k profit. Rinse and repeat. They don't bother trying to keep you there by providing value because that increases their costs significantly. Once you're at the page and the ads are loaded, the content doesn't have to be useful or interesting at all. They've made their money from you and that single pageview was all they wanted. This is basically Web spam. There's different variations of this but this is the most basic. An arbitrage of sorts.They can't attribute the lost visits to the ads. They're not trying to make a site that produces value. They're focused on "making money." I work in tech. Far too few people understand that you can't make money if you don't produce value first. Many think it's the other way around.

what's actually happening to us when we "burnout"?
|
Will power is finite. It's not an unending well like some people would like you to think. For those that willpower comes easy to, they can by very dismissive of those for whom it comes very difficult. Might take you 5 will powers to not eat that cookie. Might take someone else 50 will powers. There are things that can motivate you, or recharge your will powers battery. But over time Over a long enough timeline, everyone can and will burn out eventually. * Repetition * Lack of motivation * Lack of results over the long term while others excel * The desire for change / newness. This phenomena basically works for everything. Careers, goals, school, fitness.

the rise and fall of KODAK, and why won't it ever be a 'giant' again
|
They put all of their eggs in the film basket. They even invented digital cameras , but because they made the money when you bought the cameras, the flash cubes, the film, AND the processing, Kodak had it very good. They saw the digital camera as their enemy . Because they didn't move their business model to go with the times , it eventually ended them. You could say they had no way to survive it anyway, but hey, maybe they could have gotten into the mobile phone business

How does the website _URL_0_ make money?
|
They basically sell you to advertisers. Either they are selling your info to them , or they are selling access to your eyeballs to credit card companies. > Does this jeopardize the truthfulness of your credit report since it can be a conflict of interest? Not really. If your credit score is inaccurately high, then you won't be able to get that nice credit card deal you applied for. So they have limited incentive to lie to you.By advertising services like credit cards and mortgages.

How are companies going to make money from Automation when their customers are all unemployed?
|
Companies don't know and generally don't care: as long as automation can increase profits in the short term -- the current and next quarter -- it's a good decision and usually provides a competitive advantage. The long term problem of having no middle class buyers is beyond the planning horizon of most companies and governments. Until we can get our heads out of our collective asses and understand that we are rapidly approaching a post scarcity economy where only the business owners and engineers will have "good jobs" and implement a workable form of universal basic income, economies will slowly grind to a halt as the wealthy hoard capital. Economies work best when money freely flows.People get new jobs. Think about how much work has been replaced by automation already. It used to take dozens of people to do tasks like till a field that can now be done by one person using machines. Do we have legions of unemployed people because of this? No, because the jobs they needed to do are replaced by new jobs supporting the infrastructure of the machinery. Yes, in the short term you lose some factory workers because a robotic arm can do their job. But the company producing the robotic arm needs to produce the robotic arm - which means sales staff, designers, support, installation, delivery, management, etc. Some workers become unemployed; the people entering the workplace after that are trained to do the jobs that have arisen to replace the unskilled ones. The argument that machinery and automation will lead to everyone being unemployed should easily be exposed as nonsense if you consider that by that logic 99% of the world should be unemployed already compared to the world as it was in 4,000 B.C. You can clearly see that is not the case. Automation doesn't truly become a problem until the automation is automating itself. We're not even close to that point.

Since a country can print its own currency indefinitely, why can't the US for example just arbitrarily pay off all its debt that way?
|
Yes. The more money in circulation, the less it's really worth, period.Let's imagine "Purchasing Power" as a cake. Lets imagine "Dollars" as tickets. The tickets serve as coupons to get a cake. > 1 Cake = 1 Ticket. If I simply print more tickets, but don't produce more cakes, the value of the tickets decreases. For example, if I print 10 tickets, than, > 1 Cake = 10 Tickets. Printing more tickets didn't increase the amount of cakes I had, it simply devalued the individual tickets. In relation to money, if you simply "print more money," you aren't actually adding to the purchasing power you have. Your just devaluing the individual dollarPrinting more money makes the money worth less, i.e. inflation.

What are gimmicks, and why are they often considered bad?
|
A gimmick is something that makes something appeal better, without adding anything in generalThe broad term "gimmick" just means something that is used by advertisements and other companies to make their product stand out and seem unique. It is usually like a cool trick or another unusual aspect about their product.

Why does cooked fish irritate an allergy but sushi/sashimi does not?
|
There was a study done with raw vs cooked pea allergies, that found there were cases where those allergic to the raw pea were not the cooked version. It was found that cooking the pea altered the allergen enough that the patients no longer caused a reaction. My hypothesis from this is the cooked allergen in fish is what your allergic to, and it's uncooked form your not. This would be impossible to say for 100% certian without actually testing you and ruling out any cooking material aswell.

The eurozone crisis. Whats going on?
|
Greece accumulated a shit load of debt. They can't cover that debt. They need the rest of the eurozone to bail them out. Other countries don't want to, but they share the same currency as Greece, so Greece failing would also hurt them.

Why are my muscles feeling sore after a poor night's sleep?
|
I can think of a few things that cause this. Most importantly, your body makes a large chunk of repairs to your muscles during sleep. If your muscles are damaged , then not sleeping well will mean your body isn't able to repair as much as it otherwise would have. Especially if you're done an intensive workout, this means you're likely going to be feeling the soreness of your muscles longer as they can't be fixed as easily. When you sleep, your body releases chemicals to do things like relax your muscles and stop you from being able to move your muscles in your sleep . If you're woken up before these chemicals have a chance to clear out, you're likely going to not be as coordinated and can potentially feel sore from it until you "wake up". A "bad nights sleep" may be the result of something that also causes you to be sore -- so it may not be the lack of sleep itself. Not sleeping in a good position can tense and strain your muscles. This can make you repeatedly wake up in the middle of the night, possibly making you toss and turn into worse positions. Things like dehydration can also keep you from having a good nights sleep, and dehydration itself will make you feel very sore. While you normally will get water if you're awake, you might not do that quickly enough while sleeping.

Why are so many retail stores uniforms a blue shirt and khaki pants?

The khaki's represent a laid-back atmosphere to make customers feel welcome and comfortable. The color blue is meant to represent loyalty, trust and intelligence.

How Saudi Arabia, Venezuela and other oil export depending countries are dealing so differently with low oil prices.
|
Imagine you have several households, and all of them have one family member with a pretty decent income as salesmen . However, some of them have to commute further than others, and have other expenses that mean they get to keep less of their total pay. If sales drop low enough, it actually costs them more to sell their goods than to do nothing. Some families deal with the problem by taking out payday loans, or second mortgages on their house. A bad long term strategy, but so long as sales eventually recover, they will probably be ok. Some of these families have been throwing extra money into savings for years, so when sales go down, they can tap into their savings . Additionally, some of these countries have been using their extra money to diversify their income sources , so they are not as dependent on the sales revenue . They can also look into selling off assets, like a second car . On the other hand, some countries spent nearly every dime as they earned it so they have no savings, and failed to perform maintenance on the car they use for their sales job, so it doesn't travel as fast anymore, which impacts their sales . Also, they defaulted on the loan for the car and have terrible credit, so no one wants to loan them anymore money.

Why is it easier for non-native English speakers to sing, than to speak, with good pronunciation?
|
That's because we repeat the sounds we hear, instead of processing the sound from scratch. Imagine speaking like drawing a horse, isn't it easier to copy one from your drawing book than drawing one from a blank piece of paper?

How did presenters create slides with text and graphics in the 80's?
|
As a college student in the 1990's I had to do a lot of these for my courses. There was a way to use a copier - certain brands of transparencies could be fed to a copier and the grapics printed on them. Our library sold the brand that worked for the Xerox copiers, back then the wrong brand would melt and jam the machine. This was a service of professional print shops. Universities had their own in-house printing services. Large companies would have their own organic print services for all those executives making "the big presentation". Nowadays you can either use an LCD projector, an flatscreen or just feed transparencies to your printer. A stock joke was the "slide show" the old film slides in a mechanical carousel that were projected. Your boring relatives did this instead of harassing you on facebook. These were also used for graphics during a presentation - see old Cold War era films.
|
When installing updates on my computer, why am I required to close applications completely unrelated to the update?
|
Hard to give a more concrete explanation without an example, but it's pretty much because applications can use common resources, and you have to make sure everything stays consistent. For instance, if you're updating some video plugin, Chrome may use it. You have to close Chrome and restart it with the new version of the plugin, you can't just paws it.

Considering the amount of crap we cram into our bodies, why is urine commonly shades of yellow to brown and not purple or green?
|
There's a few reasons. 1) artificial dies and food colorings can't always survive the digestive tract intact, so they break down into their constituent parts, which aren't always as vibrantly colored. 2) The digestive tract may not pass the dyes into the bloodstream, so the kidneys may never have the opportunity to filter it into the urine stream. 3) Your poop can easily be multicolored. Just eat a heavily dyed cake, and see what happens 6-8bhours later.

Why does some cheese have holes?
|
The answer to your question is "a big-eyed bacteria named Sherman". First, a bit about process. If you want to make cheese - any cheese - you need the help of bacteria. When you add bacteria to milk, it makes lactic acid and gives the cheese a lot of its taste. Once that's done, a milk-clotting enzyme called rennet is added to coagulate the milk, and the cheese starts to look and feel like custard. After that, the cheese is cut into small pieces to begin the process of separating the liquid from the milk solids . Large curds cooked at lower temperatures give soft cheese while small curds cooked at higher temperatures give harder cheeses . The important bacteria in holey cheese is called *propionibacter shermani* . Once Sherman is added to a cheese mixture and warmed, he forms bubbles of carbon dioxide; by the time these bubbles "pop" the cheese is already too solid to fill the newly created holes . Cheesemakers can control the size of Sherman's eyes by changing the acidity, temperature, and curing time of the cheese mixture. Sherman's peekers are controversial these days. The U.S. Department of Agriculture recently created new guidelines that regulate the "hole size" of domestically produced Swiss cheese. The scandal is that the USDA reduced the standard size of the eyes by about half, because new cheese-slicing machinery was getting caught. The Swiss aren't pleased by the revised guidelines, and insist that "Emmentaler" should have eyes as big as possible! **edit** - so what does it all mean? That [this picture] is a lot more scientifically accurate than you 'd think.Well, it's because bacteria in your cheese fart while it's made.

Why do websites like Facebook and Youtube feel a constant need to change format?
|
Well that's internal information, so people who don't work at one of the companies in question can only guess. I'll take a shot at it, though. First, just because a certain design works doesn't mean it's perfect. Everything can be improved, and Facebook and Google probably think they're doing exactly that. Second, changing things keeps the site "fresh". Or maybe it's better to explain with a negative - they don't want things to become stagnant. There's some psychology that dictates new things are better than old things, even if the new thing isn't really any better. Third, you say no one is ever satisfied with websites changing, but the reality is the *vocal people* are never satisfied with websites changing. People who are satisfied just don't say anything. The hard part is figuring out how many vocal people there are and whether they make any good points, which often they don't. Fourth, designers may be trying to justify their existence by coming up with "improvements" all the time. I hesitate to add this point, because I don't think it's very likely and I know some guy who hates every redesign everywhere is going to run away with it, but there's probably a few companies out there with this problem. Now you ask why reddit hasn't changed. Most likely it's because they can't pay for it. Reddit is not a profitable company yet - they were just shy of breaking even last I heard anything - so they probably don't want to pay for anything they don't have to. Also, while they can change the layout of the site without too much trouble, adding images would take quite a bit of extra bandwidth, which is easy to translate into other costs. Looking good is expensive.'If it ain't broke dont fix it' means nothing to executives. If they aren't changing anything, what is their purpose within the company? They have to prove their worth with new innovative changes to boost revenue and other bullshit.

What is this cosmetic product really? Where does it come from?
|
the complex names really just come from the molecules themselves. If you're trained in organic chemistry, you can read the name and know exactly what elements and how many are in the compound. It goes a little like this deca - 10 methyl - A carbon atom bonded to 3 Hydrogens, so 10 of these. cyclo - arranged in a circle penta - 5 siloxane - a molecule consisting of only single bonds of two silicon atoms bonded to an oxygen atom, so 5 of these. A quick lookup will pull up a picture of the molecule, which is exactly as I just described. It's just a naming system to make it easier for professional to know the properties and makeup of a compound. They're created by chemists and chemical engineers, who have studied years and know how molecules work. So if they want to keep something moist and maybe promote collagen like in make-up, they 'd research it for years and come up with a chemical like the one you're curious about. Specifically, it acts an emollient, a chemical that makes the epidermis and dermis soft and plyable, AKA a moisturizer. When people like to use "natural products" let's say like aloe, they have very similar complex compounds. In fact, all chemicals have organized naming system, even water. "Dihydrogen monoxide" is technically the name for water. From just this, someone can see its a covalent bond with two hydrogen atoms and one oxygen atom.

Why aren't the oceans getting saltier?
|
They are getting saltier. The reason we do not notice is that there is a very small percentage change even over millions of years. The dead sea is a very small body of water compared to the rest of the ocean and its relatively isolated compared to the most oceans/seas. the dead see also would not of gotten that much saltier in recent times if it was not due to the sea being evaporated in human made basinsThis is a very good question. For a while, scientist actually estimated the age of the Earth at less than 100 million years based on the salinity of the ocean. This is actually false, as it turns out that salt does not stay permanently in the oceans. Elements of the ocean are being constantly recycled and leave the water. As plate tectonics shapes the Earth, sea beds rise and evaporate, leaving large salt deposits. Oceanic plates subduct and melt into the Earth which causes volcanoes to erupt which spew material containing salt that becomes incorporated into the land, which then starts the process all over again. Geologists today believe that the salinity of the ocean is in a state of equilibrium and that the amount entering the ocean is about the same as the amount leaving itThere are 15 Quadrillions of tons of salt in the oceans, and the rivers deposit only 4 Billions of tons of salt per year. This would mean an increase of 0,000000266% per year. However around the same amount of salt settles to the ocean floor every year. So it mostly equals out. On the other hand, because of the global warming a lot of previously frozen fresh water is being deposited in the oceans. This is actually causing the oceans to be **less** saltier and not more.

I'm aware of optical and auditory illusions...are there illusions for the other senses i.e. smell and taste?
|
There are but there probably are not as many because sight and hearing can be replicated easily , while smell and taste require actual physical particles. For taste, there is a fruit called the miracle fruit or miracle berry that after eating them, it causes sour foods to taste sweet. This is due to a chemical in the fruit called miraculin, a natural sugar substitute. Although the method is not completely known, it is suspected that the miraculin changes our sweet taste receptors to also react to sour, causing this effect. For smell, it's possible to overload your smell senses. If you smell more than 30 different smells at once, you end up smelling the same thing as if it were a different set of 30 other smells: _URL_0_

When it comes to movies/tv shows, what is the difference between directors and producers?
|
This can vary a lot from production to production. However, generally directors tend to be the one with the vision, on the set telling how the actors should act and how to present the story. Producers tend to be the ones making sure the tv show/film is on a reasonable budget on time, and the channel/studio/sponsors/production company are all happy with the finished project. The Director is in essence the artist, the producer is the realist who makes sure it get's *made*. Again, this varies depending on the director and producer involved. Steven Spielberg for instance has been a producer on many projects acting as a shield between the director and the studio to make sure certain risky elements are allowed into the production. Other times, producers go crazy with power and make weird demands for things that *must* be included in the film/show.The producer is more on the business side of things while the director is more on the artistic side of things. Producer is in charge of setting up finances and contracts. Director is in charge of selecting the talent and setting up the camera shotsThe director tells the actors and stagehands what to do. The producer gets the money and tells the investors that they are going to make a lot of money. Almost completely different jobs.

Does Listening to An Audiobook Affect the Brain the Same Way Reading a Book Would?
|
No. Reading text and processing auditory language involve separate brain structures, although many people [sub-vocalize] while reading, involving both brain structures. Another major difference is speed and comprehension. Some people comprehend text better than audio, and some the other way around. If your brain prefers text, you'll retain more information from a book. If your brain prefers audio, you'll retain more information from an audiobook. Typically, most people can read a book much faster than the narrator in an audiobook speaks, in either case. However, both styles of reading a text have similarities as well. The way our brains visualize a scene from the text, such as when a room is being described, is identical in either case. If the room is described by a narrator, or you read the exact same description in the book, you'll imagine almost the exact same room - I say almost, because the narrator's voice can have an impact on your imagination, depending on their accent, enunciation, emphasis, and gender.

Two objets at certanly distence. Can we put them closer each other by the half distance indefinitely? . I mean the half of the distance, then the half of that distance ......thx
|
Theoretically, in abstract terms yes. There will mathematically always be another half distance you can divide by. But real world physics don't permit for this. There is a phenomenon called the Planck Unit, which I suppose you could think of as the "resolution of the universe". Much like a screen cannot show something smaller than a single pixel, the Planck unit is the smallest measure of spacetime anything can occupy. You literally cannot break spacetime into a smaller amount in real world applications.

What is the point of putting a video consisting of only a still image onto a Facebook page?
|
Hey there! Facebook's algorithms place more 'value' on a video, and will place it higher in the feed, and is more likely to deliver it to more of the people following your page. You get more 'bang for your buck' by placing ad money in a video instead of a static image. Movement also catches people's eye, and they're more likely to pause to look at a video. Making a still image into a looping video is a really lazy way to take advantage of that. Source: Social Media Manager for a company.

How does Netflix make money/earn a profit off of Netflix Original TV and Films?
|
The same way any channel makes money by producing shows. They produce something because they want you to subscribe to their channel. They license stuff out based on the show. They make a dvd and blu ray of the season. They sell it to syndication on cable channels. If it's not fantasy stuff like Game of Thrones they can get advertisements in the show like characters using an iPhone or something. It's really no different from HBO, Showtime, etc. except Netflix isn't there on your regular T.V. when you go to channel 601 or whatever. Even that line is getting blurry.

Why do some games run on a mac but not on linux if both are unix based os.
|
They're not UNIX-*based*, they're UNIX-*like*. MacOS is based on FreeBSD, which i a very different operating system than Linux. Furthermore, MacOS has it's own *completely* custom GUI and graphics APIs than Linux does. Only the very, very basic components of a game would be easy to port over.In short, because they are very different. Linux uses ELF binaries, OS X uses Mach-o. The way you generate sound and draw on screen is different. As a fun fact, in GNU/Linux, Linux is the kernel and GNU stands for "GNU is not Unix"
|
When copying files from one device to another, why does the transfer speed slowly decrease over time?
|
Your computer can only create and allocate files on a device just *so* fast, so if you have lots of little files there will be a lot of overhead of creating the files themselves on the destination drive. You will see a speed increase if you're copying larger files as your computer doesn't have to worry about naming etc and can just focus on transferring the bits that make up the file itself. If you are copying a large-ish file and you are seeing a definite decrease in speed first try another copying program ). Still an issue? Try copying the same file to the same device from another computer. If it is a decently stable speed the whole way using their computer your USB controller may be out of whack - try reinstalling the drivers for it. Otherwise it could very well be the cable or even the destination device itself.

Why do humans find eyeless or pitch black eyes scary/unsettling?
|
It's called The [Uncanny Valley], and it's not limited to eyes. Basically, the closer something gets to looking human, the more we can sympathise with it - until it gets to be about 95%-99% human. Then it *freaks us the hell out*. Basically if something is just a bit off. Eyes may have the additional trigger of us being A. Very attuned to identifying Human faces, B. Vision being our primary sense, and C. Knowing how sensitive eyes are.

Why do lakes freeze but rivers don't, in the same temperature?
|
Water in lakes is still, so it has time to freeze. Rivers are flowing, so water is constantly moving, making freezing much more difficultThe water particles of a river are vibrating more than that of a still lake. Heat is the name for the amount of kinetic energy of the movement of particles.

Why can’t we capitalize numbers like how we capitalize letters?
|
We do; we just stopped mostly using the “lowercase” numerals. [This] is what numerals used to look like. Some typefaces still provide such “old-style numerals” or “text figures” instead of or in addition to the newer “lining figures”There is no point or meaning to do so.Numbers are exactly what they are.Letters are to build up a language created locally and then interact with others.Maths / numbers are universalBecause our number system comes from Arabic, which does not have capital letters. We merged their numbers into our writing system.

How/ can people be sentenced to multiple 'life-sentences' in prison?
|
People are given a sentence for each charge they are guilty of. If you commit 4 murders you can be sentenced to 4 separate life sentences. It's largely redundant but allows prosecutors to stack charges against people and allow justice in each of the cases of the criminals victim.Because if you commit 48 crimes, and the penalty for each is a life sentence, that's 48 life sentences. There's no procedure to formally combine those sentences, or turn them into "you ain't never getting out yo", simply because there's no good reason to spend time creating such a procedure.It's redundant charges to make sure he doesn't go free if one of the charges gets dropped due to technicalities or some other reason. For example, lets say a guy was getting charged with 4 murders and the prosecutor only decided to pursue one charge since he'd go to jail the rest of his life anyway. He's tried and convicted and sentenced to life w/o parole. Later on, it's revealed the one murder charge they pursued he didn't actually commit but he definitely committed the others. He'll go free because the one crime he was tried for he was innocent. If he had instead pursued all 4 charges and got 4 life sentences w/o parole, it wouldn't have mattered if one got dropped because the rest would be there to make sure he remains in jail.

Why have they not started issuing social security cards in plastic form like the DMV does with drivers licenses?
|
Oh god somebody please answer this. I never understood using that damn piece of paper as an item for your I-9 verification. It looks like something a half baked forger can copy.The reason I've always heard is so that it will deteriorate more quickly if you ever lose it.The reason for this is if you lose it outside it will be destroyed fairly quickly, its s piece of identification you are not supposed to have with you at all times if you read the back of the card. Keep it secret, keep it safe.There's no reason to carry it with you. I have my original card, issued at birth 40 years ago, and it's in fine shape. There was also a time, farther back than when I was born, that SS cards actually said NOT TO BE USED FOR IDENTIFICATION right on them. Oh how times have changed.

You do not want to learn. I have this, and it's a disease. I have no control over it. I don't even have it severely and have to put a jelly paste in my eyes multiple times a night which is also a pain in the ass in the morning. If I don't put the paste in my eyes I wake up with a horrible burning sensation from my eyes drying out. It has taken as long as 48 hours to recover from not using my jelly.

Who is a bigger drag on healthcare premiums: The uninsured or the insured sick?
|
both? neither? In the US you're going to struggle to find someone who actually turns away a person in need of healthcare, even if they're uninsured. They will go the the ER, the ER will process them, and try to bill them for whatever they can. In light of the fact that this uninsured person can't afford insurance, they also can't afford to pay the ER, so the hospital takes that patient's cost as a loss, but then in the bigger picture, adjusts it's cost of business to take into account that patient, and all the others like him. This translates over to insurance costs, even tho he wasn't insured. Now, lets say he had insurance, well he only will use it if he's sick, in which case, he's incurring expense to the insurance company. To answer your question, the only people who make insurance premiums go down are the insured, healthy people. if there were a larger distribution of healthy people who still paid for insurance, the cost would go down.

how does muscle contraction and the sliding and Calcium thing work?
|
Thats not eli 5 material I think but anyway. Muscles are bound od something like 2 kinds in planks laid in rows: row of planks a, row of planks b, row of planks a etc etc. Planks b have one head at a 90 degrees angle at each ens, towards either the row above or below. When muscles contract those heads bind to planks a, while also turning slightly, moving planks b. That causes them to slide slightly, shortening the muscle, aka making it contract. I believe calcium just works in passing the transmitters even before that, but I had those classes like 7 years ago so that might not be accurate. Please respond to this so I'll find the post, I'll draw a schematic.

What's the legitimate purpose of a water tower?
|
It regulates water pressure for an entire area with a single control, by using gravity to create water pressure. You fill up the water tower, and the water coming out of the tower is under pressure from the weight of the water above it. Otherwise you would need to have a pump that keeps the pressure up, and it would have to quickly respond to changing water demands. The water tower handles all of that by itself without anything complicated.In addition to dsampson92's comment, water towers can also provide water to areas even during a power outage. Since most city houses don't have pumps, the city can provide backup power to a water tower pump and continue water service. Also even if the backup fails, the pressure in the tower will last quite some time before water is unavailable.

What gives a person their own unique tone or pitch in their voice, and why are men and women voices so vastly different?
|
There are actually quite a few factors. The larynx is the primary organ in vocalizing. It's where the vocal chords are located, and different shapes will result in different tones. Men tend to have a larger larynx with longer vocal chords, giving them a deeper voice than women. In addition to the larynx, the shape of the pharynx , mouth, tongue, and nasal cavity all influence the outgoing sound.

How did someone decide where all the keys went on the common keyboard? Was it random or is there actually a scientific reason behind their placement?
|
The reason for the QWERTY keyboard we use today goes back to the first mechanical typewriters in the 1860's. At first, typewriter keyboards were arranged in alphabetical order, but there were problems--specifically, when quickly typing two letters that were next to each other on the keyboard, the mechanical arms that did the printing would jam. Several different keyboard configurations were tried in an attempt to avoid jamming, including some designed to force typists to slow down The QWERTY keyboard was designed to separate the most commonly used letters from each other, to help keep them from jamming. As it turns out, the QWERTY keyboard did its job, yet still allowed speed typing--my greats grandmother could type 120 wpm on a mechanical typewriter before she died. Other styles were developed, but they didn't catch on for one reason or another, although at least one is still seen in use occasionally: the Dvorak keyboard, invented by a man named Dvorak, is still occasionally used for speed typing.

what is the difference between body wash and shampoo? If im hairy cant i just use shampoo for my body?
|
Body wash can be excessive harsh on your hair, stripping it and turning it into straw , Shampoo is gentler, generally, washing out any hair products and environmental buildup without stripping it completely. You can use shampoo on your body, but, personally, I've never used a shampoo whose scent I'd like to have spread over my body. If you like you could skip shampoo, you could use a co-washing method, which is using conditioner to wash your hair. If you have a oily skin/oily scalp/oily hair then this is probably not a method that'd work for you.

How is it legal for a Greyhound bus to allow people to stand up in the middle of the aisle going 65 on the highway when seatbelt laws are so enforced?
|
[The answer to your question], and [a story from a kid inside a flipping bus].The reason people get thrown through windshields when they are not wearing seatbelts is that their bodies keep moving even though the car has slowed down or stopped. This is because of inertia, the tendency of objects that are already in motion to stay in motion. Buses have a lot more mass than other vehicles, so they have more momentum. This means they stop more slowly when they hit something or when the driver slams on the breaks. Therefore, the deceleration is slower and people don't get thrown quite as forcefully. That's still no excuse not to have seatbelts in buses in my opinion, but there are the physics for you: _URL_2_", 'Estonian here. Seatbelts are very strongly enforced here, with pretty high fines I might add, but buses seem to be the exception. City buses have no seatbelts at all while most intercity buses have seatbelts, but they are only reccomended, and nobody uses them, not even the driver. And buses, in Tallinn at least, still have the so-called "teeth busters" [Here's a picture taken inside a pretty much brand new bus in Tallinn.] Those buses break quite fast, so in case of a sudden brake, people standing up may fall down if they're not holding on to something. ', "It's not. I was on a Greyhound or Trailways bus where a guy gave gave up his seat for a girl. The driver went up to the guy, the only passenger standing, told him no one is allowed to stand. The passenger started to explain. The driver told him he wanted to talk outside. When the guy went outside, the driver shut the door and drove away. I'm pretty sure his luggage was still on the bus.

If Ant Man just shrinks but stays the same mass, how come when he runs on a bad guys weapon it doesn't tilt forward with 150lbs pressing down?
|
OH SHIT! YOU SIR, youuuuuuuuuuuuu should not say such things if I were you that is uhhh .very observant of you does he stay the same mass? So he's just more dense .I feel like that opens a HUGE can of worms for this scientifically oh well comics, super heroes, what you gonna do", 'Seriously? It's because "comic book". Why doesn't spiderman have to eat a metric fuck ton of food to generate all that web he spins everywhere?', "well they make a huge point in the movie to say he has no powers other than shrinking. It's very clear that his mass is the same, they keep saying the force he hits with doesn't change. All he is, is a 2 inch man for all these reasons in the movie, I have to get it explained.Everything about Ant-Man's ability to get small requires that the force of gravity and the nuclear strong and weak forces be altered from "normal" reality. You can't "shrink an atom". Atoms are already as small as they can possibly be and exist within the framework of physics as we understand it. Since whatever tech is used to make Ant-Man shrink is therefore capable of altering the very fundamental attributes of physics, any question of "why x" afterwards must be answered with "because story" for there is no other possible explanationBecause it would be inconvenient for the plot to do so. Obviously for people with a sharp mind that makes the fiction obvious and annoys the hell out of them because it destroys immersion[VSauce3] just released a video explaining a lot of the science/physics of shrinking.

Why was the "Great Potato Famine" so devastating?
|
There was actually plenty of food there, but England was claiming most of it and having it shipped across the channel. On top of that because of the potato the population was well above what natural sources could provide. Even if you fished the waters till nothing lived it wouldn't be enough food and still problem one of England claiming a lot of the food production.

What's the difference between someone who has a learning disability and someone who's just stupid/slow/dumb?
|
I would think of it in terms of a computer. Stupid or dumb would just be someone with a slow processor. Everything works fine, it just doesn't work that fast. A learning disability would be a hardware defect. Maybe there is a problem in ram causing a corruption of data the computer is working perfectly fast enough, it just encounters errors which make it difficult to complete a certain task.

Why did adding laugh tracks to comedy shows become the norm?
|
Originally, the shows were filmed before a live audience, or just aired live with an audience, so people got used to the laughter and producers thought that they wouldn't like the silence. A fair number of modern shows still have the audience, actually. I'm not sure how many actually add a laugh track.

What makes something Machiavellian and what are some examples?
|
Machiavelli wrote the Prince, which is a guidebook for political advancement through social climbing, manipulation and what we would now think of as branding or PR, and then instructions on how to consolidate and maintain power once you acquire it. In short, it's a how-to book for scheming your way to individual success at the expense of others. Vladimir Putin might be the current figure who is most visibily Machiavellian. The annexation of Crimea was pulled off using espionage, deceit, trickery and political maneuvering, and is a pretty good example. Putin's switching back and forth with Medvedev between the offices of the President and Prime Minister to avoid term limits while still maintaining power is another good example.

What is inflation and deflation and why is it bad?
|
Inflation is when prices over time increase and deflation is when they decrease. Another way to say it is that inflation is currency becoming worth less and deflation is when it becomes worth more. Neither is inherently good or bad. But you can have a stable value of currency too, it's just rare. Say you have a loan for 100$. You have to pay back that dollar amount. So if there's a period of inflation, you effectively have less to pay back because 100$ doesn't go as far. So you would like inflation in that case, but the bank wouldn't. But if the currency deflated in that time, you would be upset and the bank would be happy.

Why don't people run out of air in a submarine?
|
Modern subs have machines called Electrolysers. Basically, these machines take seawater, and split up the hydrogen and oxygen molecules and the oxygen is then stored in tanks for use. Subs also have scrubbers that remove CO2 and recirculate the oxygen from when we exhale.Depends on the submarine. Old submarines had to surface to cycle their air. Newer submarines have what's called CO2 scrubbers. As you breath out, you exhale carbon dioxide. The scrubbers inhale the CO2, and use a chemical reaction to separate the carbon from the oxygen, then pump the oxygen back into circulation. Watch the movie Apollo 13. They jerry-rigged a CO2 scrubber out of spare parts when their capsule failed. Subs work the same way, only on a much larger scale.Regarding "scrubbers", the same thing happens when someone is anesthetized for an operation. The ventilator recirculates exhaled air through an absorber, which binds CO2 in a reaction forming heat and water. The air is then recirculated into the patient. CO2 is the reason for the "I can't breathe"-feeling. Removing it, you can breathe air with a lower oxygen content comfortably.

why my helium balloon stops floating after a few days
|
Helium is an extremely small molecule, it will squeeze out through even the best the seals and through the tiny gaps in the balloon material itself. Eventually enough has escaped that the balloon is no longer buoyant.The seal isn't perfect, so regular air gets in and helium gets out over time.

Why does the body wake up starving when it consumes a lot of food before bed, but wakes up fine if it doesn't?
|
Hunger isn't always regulated by whether you have enough total energy. Other factors such as whether your body thinks its using up a lot of energy affect hunger as well. When you eat late at night, especially something sugary or filled with simple carbs, you get a boost of glucose in your blood before bed. Your body releases insulin in response so that your cells can utilize the glucose. As your cells take in the glucose, your blood sugar drops, which causes you to get hungry. As a result, you wake up hungry. If you don't eat late at night, then you don't get the insulin boost before bed and your blood sugar won't drop as much. Therefore, you aren't as hungry.
