how does bail work with bailbondsmen and why does this exist?
|
First of all, let me explain the concept of bail. Bail is an extremely old way of making sure that people show up for their trials without having to hold them in jail until the trial. To make sure you don't run , you have to pay a considerable sum of money. You get the money back if you show up at your trial. You don't get it back if you don't show up, or if you commit more crimes. This system was obviously very important in the days before photo IDs and modern record-keeping, and it is still important today. But what if you don't have the money to pay your bail? Enter the bail bondsman. They agree to pay your bail for you, at the cost of a non-refundable percentage of the bail. If they didn't provide this service, you would just have to sit in jail until your trial, assuming you had no friends or family to bail you out. If you don't show up to your trial, the bondsman loses the bail money, *unless* he can find you and bring you back to court. This gives him a financial incentive to make sure his customers don't flee. If they do, he can hire a bounty hunter , whose job is to track them down and arrest them, taking them back to face trial.

What would be the bodily effects of taking a pill giving you 17 times the amount of daily Vitamin C for a year do to your body?
|
Vitamin C is water soluble, meaning that the body takes in whatever level of vitamin C it needs and flushes the rest out through the kidneys. The body does not store Vitamin C, so any additional dose is removed. The percentages of RDA appeals to the "more is better" and does nothing but create urine high in Vitamin CNot a medical expert, but I am a chemist that used to take that kind of vitamin c Probably nothing but make his urine REALLY bright yellow. Vit C dissolves really well in water but not in the rest of the body. This means that it will move quickly from the stomach to the blood stream and get filtered by the kidneys to the bladder VERY QUICKLY and very efficiently. If he starts having nausea, diarrhea, vomiting, heartburn, cramps, headache, or insomnia, then he should seek medical attention immediately. Unfortunately any problems he could have from this would be chronic and related to high iron levels . In reality, most people do not need extra vitamin c in their diet if they are eating fruits and veggies regularly. If he wants extra, a glass of OJ a day is probably plenty. _URL_1_ _URL_0_ ', "Each vitamin is slightly different, but Vitamin C is one of the safer ones to take larger doses, where typically the most that would go wrong is diarrhea, vomiting, and nausea. While those things can lead to other things, such as dehydration and malnutrition, most people don't get to that level. The suggested thing for anything is look up what the recommended daily intake of something is and not to exceed that, since overdoing it on anything will eventually lead to some sort of issues. EDIT: _URL_2_ ChubbyEmu also recently did a video on the subject as well worth checking out!", 'This is typical of drinks like emergen-c. Your body absorbs what it can of the vitamin c, the rest is harmlessly discarded.

Where does the items deleted in the Recycle Bin go?
|
They essentially just get marked for re-writing, meaning that now the computer can write over that space with whatever. So they aren't deleted until something is written over it. I could be wrong however, i pulled this out of my ass-brain.On Windows XP "deleted" files are listed under a folder named RECYCLER. In RECYCLER there is one folder per user with a name something like: S-1-5-21-1708537768-492894223-1343024091-1003 To answer your question, no, they are not deleted immediately, but periodically the system will clear out old files from the Recycle Bin as it becomes full and reaches the size limit set by the system. You can right-click the Recycle Bin icon and look at the Properties tab. In there you can change the size of the recycler, and edit a few of the parameters. If you're unsure what you are doing then I suggest leaving it alone, and let Windows manage it.

How do mobile phones transmit calls over the same bandwidth at the same time without interfering with each other and always finding the right reciever?
|
GSM doesnt use the same frequency for all communication, and not the same time. CDMA is a method that allows everyone to send at the same time and distinguish them.

Why don't birds get cold in the wind?
|
Birds have insulating feathers called *down*. They trap air close to the body so convection can't pull heat away. To get their feathers to do this, their muscles can make the feathers stand on end -- these are *literally* goose bumps. By the time it gets warm, they have shed many of their insulating feathers due to molting, and what remains is kept tight against the skin, allowing for maximum cooling.

How do airlines make a profit?
|
The short answer is that the airlines are _exceptionally_ good at price discrimination. The longer answer is that not everyone pays the same price for the tickets they have. This is very obvious when you think about business class vs. coach - the business class tickes are often > $1,000 a seat for domestic flights and can be > $10,000 for overseas flights. However, there is significant difference in the prices of coach seats too. I fly for work every week and I promise that I pay _much_ more for my tickets than you ever had. I tend to book them closer to the departure date, I tend to select very specific flights with very specific times and destinations. Moreover, I am much less price sensitive because I'm not paying for the flight directly and they are prepared to pay a bit more to have me where I need to be when I need to be there . The airlines know all of these things about me so they adjust prices for us accordingly. When a leisure traveler books a ticket, many of these things change - you book further in advance and you care less about specific flight times; all you care about is price.

How do Human Beings "absorb" energy from an impact?
|
There are a lot of sources for energy to go here. Most of it probably ended up being converted to heat eventually. Here's a runthrough of what might have happened: * The child-bike system has some amount of kinetic energy and is heading toward you* The bike collides with you, skidding off to the side. The energy of the bike is largely dissipated through friction with the ground, with a bit of the energy going into sound and the energy required to chip or bend parts of the bike.* The child collides with you. This temporarily deforms your body like [this poor guy taking a football to the face]. Initially, the pressure of the child hitting you would locally heat up your body, though it would quickly cool with decompression. The child hitting you will excite "vibrational modes" in your body, just like hitting a piano string will make noise. These will gradually dissipate due to internal resistance of your body, becoming heat. * You and the child are sent flying due to the impact. You come to a stop after sliding across the ground. Your initial energy went into * Removing bits of your skin * Heating the pavement through friction * Making a bit of noise * Further "impact energy" due to any large objects you might have hit in turn It's hard to say where exactly the energy will go in what proportions for a complex system like this, but it's generally a good guess to think that the vast majority will end up as heat. Try dropping a bowling ball on the floor a few times. You'll notice it will get quite hot.

Why is it sometimes taboo to classify transgender folk as having a mental illness?
|
Because one criterion for mental illness is that the behaviours and thoughts the person is experiencing keeps them from being able to fully function day-to-day. For example, anxiety disorders and depression can impact a person's ability to go to school, to work, to hold social ties, etc. Feeling like one's gender is not strictly male or female is not an illness. It is an expression of the self, just like whether someone is neurotic or secure, introverted or extraverted, etc. Mental illness has to do with the impact on the person, just like any other illness; it is not because other people feel uncomfortable.In modern psychology mental illness means something that is preventing a person from leading a happy fulfilling life. People are allowed to be abnormal as long as they are not harming others and themselves. It is not taboo, it is just viewed as not harmful enough to qualify as "illness"Because there has been previous classifications of homosexuality as also being a mental illness and misguided "treatments" were created to "cure" the mental illness. Medics and scientists don't want to make the same mistakes twice.

Why does a vehicle 15 mph faster than you appear to gain a much greater distance from you depending on your own speed?
|
Because when sitting still, you have all of your environment in the same relation to the moving car as you. However when you are moving 70mph, the only reference point you have is your car and the other car to judge the speed difference.

Why do we experience a 'burning' sensation in our eyes if we haven't slept for a while or immediately after waking up?
|
It might be that "crusty" discharge from your eyes called rheum that is released during sleep. It looks likes sand in your eyes hence the saying. The burning from sleep deprivation is just like what sleeplessness does to the rest of the body, give it fatigue.I guess it's got to do something with your lacrimal glands. They basically secrete liquids to keep your eyes moisturized while you're sleeping. However, they often don't work properly if you don't get enough sleep. Dry eyes can also be caused if you sleep with your eyelids half-open. If the problem persists for long, you should go and see an eye doctor. Try drinking a glass of warm water just before you sleep and immediately after waking up; this will hopefully lubricate your eyes

When someone sues another person who's not financially well-off for a huge sum of money, how do they get paid?
|
Essentially she won't. She can attempt to take money from wherever he may have some, and then on top of that try to take a percentage of any earned . But the reality is she won't get a dime.

If we can only see the "observable" universe, how can we make conjectures about things like its beginning?
|
What they mean is that eventually space will be expanding fast enough that all the light will be redshifted out of detectable range. The universe isnt expanding because of the motion of the galaxies. Space itself is expanding. Every second there is more space between us and distant galaxies. Our relative spatial velocities could be toward each other but space is expanding faster so we move away from each other. This expansion is proportional to the amount of space so like compound interest the acceleration due to space time expansion increases. Eventually we will be alone in thw universe. Now this all assumes that expansion is universal and non reversible. At some point in the future we could have the reverse happening. Im not sure what physics says about thatYou are correct, there could be endless stars and galaxies beyond 14 billion light years and we have no way of ever finding out.

How do people on drugs, such as meth, supposedly get superhuman strength, taking multiple people to subdue them etc?
|
People are generally stronger than we think. We have built-in safety margins, like the warning line in a pressure valve, so that we don't accidentally injure ourselves these safety margins are often very cautious, preventing us from exerting anything like our full possible force . Some drugs either directly shut down the mechanisms , or otherwise prevent us from being aware of them. A big part of these mechanisms is pain responses. Drugs often significantly mute pain. So, you have a person who is unaware of pain and is being as frantically strong as people can be in a severe panicked emergency, versus people who are still very aware of their own pain and perceived limits . So, it's not that the person has _extra_ strength from somewhere, it's that a person who has had all the limits taken off, against people who are still severely limited in multiple ways, _appears_ superhuman.

If fusion reactors fuse hydrogen into helium, wouldn't we run out of hydrogen at some point?
|
Hydrogen is the most abundant substance in the universe. 90% of all the atoms that exist are hydrogen. There is so much hydrogen locked up in fossil fuels that we could just use them for millennia before we even started using water, or sending spaceships to collect it.Theoretically, yes. But there is a LOT of hydrogen. There's about 1.35 *10^21 kg of water in Earth's oceans. Water is about one ninth hydrogen by mass, so that is about 1.5 *10^20 kg of hydrogen. Seawater contains about 200 ppm of deuterium , which comes out to a deuterium reserve of 3 *10^16 kg. Assuming D-T fusion , in which a deuterium nucleus reacts with a tritium nucleus to form a nucleus of helium and a neutron , with 17.6 MeV of excess energy, 0.376% of the input mass is converted into energy. The total world annual electricity consumption is about 6.4 *10^19 J, which is about 710 kg mass equivalent. Thus, per year, at 100% efficiency, about 75000 kg of deuterium would be needed , which would, at current power consumption, last for 400,000,000,000 years. Even assuming only 20% efficiency and four times higher electricity consumption than current figures, deuterium reserves would still last for 20,000,000,000 years. So, in conclusion, no, we would not run out. If we do D-T fusion, a lithium shortage will become the limiting factor a lot sooner.

Why do we have the capacity to hate ourselves?
|
Free thought and free will has many positives and negatives. Increased intelligence means that we also can see the uglier sides of things, and well .Humans have evolved as social creatures. In addition to caring about things from our own point of view, we have parts of the brain dedicated to caring about how we must seem to others. A human lacking that function -- not caring at all about one's impact on others -- is called a *sociopath* and is considered mentally ill. But many non-social animals could be considered 100% sociopaths because this just isn't part of how they operate. Caring how others see you includes the ability to find your own conduct unacceptable or even disgusting.

What is the "shy bladder" and what can people do to get over it?

> What's going on You're having an expectation that someone may intrude on your urination, which in turn makes you unable to relax. > how can I make it easier on myself Find someone to squeeze you. /meta You may need to somehow snuff out all surrounding sounds to help you unwind and start peeing.hey there! I have that problem myself from time to time, and its weird, i started to do math whenever it happens:817 divided by another primenumber. Whenever i think about it, its fine immediately. i guess the habit of thinking of something else makes it easy. Put your mind offJust use math, multiplication works for me. The more difficult the problem, the easier it is for me to pee. Really helps when the movie gets out and the bathroom is packed. Found the tip on Reddit and it has worked ever since.

- why do most honour killings involve murdering the victim? Why not kill the rapist instead?
|
In such cultures women are viewed as property, to be bought, sold, or traded. The honor killing is in retribution for the perceived dishonor of allowing themselves to be raped, as it damages or destroys their value to their male owner. It is fucked upIf someone smashes the windows in your car, take a shit in it, slashes the tires you would get a new car, it was just property damage. Maybe youll find the dude who did this but either way that car is useless. Most of these cultures view women as property so not only should it be replaced but its broken goods, so broken you have to set the car on fire so your neighbors dont give you shit for having a smashed up wreck in your driveway.Because it's not about the act, or the property being damaged, or the people involved. Its about maintaining family honour, and removing the mark against the family. The girl doesn't factor into it at all, because she was supposed to protect herself, and the family was supposed to help her do that. They failed, and so it has brought shame ~~too~~ to the family. To rectify, they destroy the evidence of shame to remove the mark on the family. Most Muslims do not believe in honour killings, by the way, nor do any sects therein publicly accept them as part of their faith.

Why is it that if you exhale like blowing out a candle the air is much cooler than if you exhale like you're checking your breath?
|
Hi, Mechanical Engineer here. I assume that when you blow out a candle, you purse your lips. Air is pushed out of the small hole and this creates a high pressure, fixed volume chamber in your mouth and exits to a lower pressure, free volume atmosphere. This sudden change in pressure causes the volume of air contained to expand and the temperature to drop, making the air you blow feel cold. This is also known as [Adiabatic Cooling] On the other hand, when you check your breath, your mouth is open wide enough that the pressure between the inside of your mouth and the air is similar to one another and the volume is no longer contained. The warm air is now caused by your body temperature heating the air as it leaves your body.It's not due to pressure drops. The reason it feels cold when you purse your lips and blow hard is because this causes air to come out faster, and faster moving air entrails more room air with it, so the temperature of the air is that of the air in the room. When you breath slower, the air isn't moving fast enough to entrain room air with it, so the temperature is that if the air in your lungs, which is warmer.

What is the significance of a full metal jacket in small arms ammo?
|
Bullets were originally just cast lead, and many people still do cast bullets this way . This can lead to lead deposits in the barrel which will hurt accuracy as well as a bunch of lead in the air . The FMJ is a copper jacket around this soft lead to make it more stable in flight as well as not leading the barrel. On top of that, lead is some soft and can lead to bullets getting deformed rather easily; FMJs are highly resistant to thisRetired US Army ordnance officer here. The FMJ is there for reliable feeding in semiautomatic and automatic weapons. As others have said, any exposed lead, especially in the tip or ogive risks feeding problems that result in failures to feed . A FMJ greatly reduces that possibility since no lead is exposed that could catch on the feed ramp or chamber.It's one way to comply with the Geneva convention's requirement for non-expanding ammunition. It's not legal for hunting most game. In the civilian world surplus ammo tends to be less expensive than other types of ammo and it's frequently used for practice or target shooting for this reason.

Why and how is it that the Windows operating system hasnt been replaced?
|
One of the main reasons is that Microsoft makes deals with hardware manufacturers to include their OS in those products by default. This starts the cycle that makes most consumers use Windows regardless of if they're at work or at home. Consumers generally don't like change, so then Windows usage seeps into other areas simply because people are familiar with using it in another context. OSX is out simply because it's tied to Apple hardware and its licenses prohibits OSX from being installed on non-Apple hardware . Much like the iOS and Android comparison; there are more manufactures out there than Apple, so by default Apple is going become niche. This leaves linux and/or other *nix OSes out there. Because Linux is an open source project and not driven by money there's much less incentive than MS to get consumers using the software.There is a massive investment in Windows from developers. The business world runs on it. Forklifting the Windows OS and expecting business to continue is foolhardy. Not everything runs on Linux or OSX and not everything has the easily managed backend of Windows. Active Directory and existing apps give Microsoft a stranglehold on the business desktop market.It's a self-fulfilling cycle. Developers find it easier to keep making software predominantly for the most popular OS. More available software means more consumers would likely still want Windows on non-Macs. In addition, commercial users want to always ensure functionality and compatibility with what they had yesterday, so they're incentivized to keep using Windows. However, as tablets, 2-in-1's, and smartphones get more important in the computing scene, Windows may lose its place at the top to Android, iOS, and maybe Chrome OS. PCs as we currently understand them may always be mostly windows, just most casual computing will be done on something other than a PC.

Why is St. Louis not as important in the United States as it once was? Is it likely to continue shrinking?
|
It was very important when the Mississippi was a big hub for transferring industrial products out of the Midwest. The small arms factory my grandmother worked at during WWII in Davenport, IA shipped through St. Louis, for example. As Midwestern industry declined, so did the shipping of those products out along the Mississippi. That said, the shrinking of St. Louis is exacerbated in the statistics. While other cities expanded their borders as their populations sprawled, St. Louis couldn't because it was not part of any of the neighboring counties. Chicago, today, makes up something like 80% of Cook County. St. Louis couldn't expand in a similar way because it couldn't take land from a county it didn't belong to.

How can a computer be infected with virus/malware/etc. by visiting a website?
|
When visiting a web page, what you're really doing is making a request to a web server to transfer files to your computer. If one of those files contains a malicious payload, and your computer executes the malicious code without being interrupted by antivirus software, it will become infected. Malicious code is usually introduced through plugins and scripts that run locally on your machine . Java, JavaScript, and Flash are the most common culprits.

why can't people inhale when they get the wind knocked out of them
|
You know when you hit your leg on something and you pause whilst cursing the pain because your leg kind of seems to go numb for a second? That's your body very temporarily immobilising the area to make sure nothing is SERIOUSLY wrong with the part of your body that got hit. The same thing happens with your diaphragm when you get hit in the torso. A second or two of no diaphragm contraction means a second or two of no inhalation.Couldn't be something to do with the diaphragm being hit? That's what relaxes/contracts to make your lungs work, so I guess if it got hit and was temporarily "disabled" slightly, it would affect your ability to breathe.

What has happened to the babysitting market in the last ten years?
|
The market is flooded. You have a lot of people who can't get jobs elsewhere because the economy isn't as strong, so there are many people able to work as babysitters. Which not only means that you have babysitters lowering their rates to remain competitive with everyone else, but also advertising whatever benefits they have to try and get that babysitting gig.

When listening to earphones/headphones, why does my music feel louder after I yawn?
|
Your ears are usually pressurized, which serves as a slight volume reduction in some cases. Over time, the pressure in your ears can accumulate. When you yawn, the muscles used relieve the pressure within your ears, "popping" them and removing the pressure, which allows you to hear better.
|
Why is it common practice to separate high voltage (120V) wiring/cabling from low voltage (24V) wiring/cabling?
|
Electrical Controls Engineer here. Basically it is to reduce noise and to not induce voltage into the lower voltage wires.With ac circuits the currents alternates through the wire generating a magnetic field. Any wire close to this can potentially interact with that field and a voltage will be created in the wire. The higher the voltage the greater the potential for a low voltage wire like 24dc or especially 4-20mA runs to have noise induced on them.

How do smart phones dissipate the heat created by the processor?
|
I think some of the answers are great, but missing a major point that I want to add: The chips in smartphones ) are built from the ground up to turn the energy in the battery into useful work as efficiently as possible. In industry terms, smartphone SoCs have truly insane Performance Per Watt, which is a unit of how much screen brightness, CPU speed, etc can be achieved using only a joule of energy every second. So to answer the question, mainly because they barely produce any heat. Heat is what happens when energy from the battery is lost, and not turned into useful work. This is why the mobile device revolution only happened recently. Chips this efficient are a very new invention.they use passive cooling such as heat pipes to spread the heat through the phone. that way it can radiate out through the entire surface. but at the same time you dont want too much heat coming out and burning your hand. so a lot of heat ends up staying inside, and the performance is throttled to produce less of it thermals are rarely mentioned in western phone discussion, but in hot places like india it's very important and you can find reviews saying how quickly they overheat, thermal scans showing how hot their surface gets, etc", 'They have heat pipes, if you watch a video of a razer phone being taken apart you can see a big copper pipeVery poorly. Which is why they cannot really perform demanding tasks for a long time. The inner body is usually metal and contacts the screen, so it can absorb a little heat and pass it to the environment, but it cannot run at full performance for long without running hot.Just to add on, the best way to prevent overheating is to throttle the CPU and design the system not to generate heat in the first place. What you may not realize is that the CPU isn't usually the biggest power draw and heat generator in a phone, it's usually the screen itself and the radio . But it doesn't always work perfectly.

X-box 360 downloadables, the entire Banjo-kazooie game is 48mbs (with heaps of animated scene vids) and a short Banjo trailer is 98mbs to download, why?
|
The animated cut scenes in the game are rendered in the game - so instead of having a recording of a video for each scene, they just have to include instructions for how the character will move. Think of it as shipping blueprints for a house versus shipping an entire houseIn the game the world is generated dynamically based on a small pallete of textures. Eg there is one road or bush bitmap and it is repeated over and over or the background is static and is only one image. The video is a recording of game play and simply due to encoding it as a video it is larger in sizeSay I told you to draw a blue square with 12 inch sides. "Just draw a 12 inch square and color the inside blue." That takes a single sentence to do so but requires you to do work to draw/color it. Now say I give you a drawing of a blue square with 12 inch sides. You didn't have to do anything, but instead of a sentence, I had to give you an entire paper with the square pre-drawn. Now instead of one square, I want 1000. Instructions still just one sentence; actually handing 1000 pages to you, not so much. That is the difference. The game code itself tells the video card / processor how to construct the objects, reusing a ton of textures and other things. Code is ridiculously small. I could hand you a few hundred lines of code and some sprites in a folder and you could use that to construct an entire world. It would take up a ton of memory once constructed, but the material to construct it is relatively small. But it goes beyond that. Videos basically work by being constructed from thousands of "images" where each pixel has to be stored and accounted for. Video compression algorithms work to remedy a large problem with that, but that's a different topic.

What is the biological explanation of when your "heart skips a beat", as in when you get scared or nervous?
|
The feeling you get when you're nervous/scared is due to a rapid increase in your heart rate. Epinephrine is released, and causes the Sinus node to increase it's rate of firing. You perceive your heart skipping a beat, but it's actually just beating faster. When hearts actually drop or "skip" a beat, you wouldn't feel anything and would most likely feel a very "weird" or odd feeling . You can have an extra beat in a normal rhythm, which can be caused by a lot of factors. Usually it's some type of heart pathology though and not due to the normal fight or flight responseIf I'm not mistaken this is a description of the moment adrenaline hits your bloodstream, which is usually marked by a sudden increase in heartbeats per minute; the same can be said for "the moment your stomach drops" -- these are moments when changes in your body happen quickly enough to be noticed by waking consciousness.It doesn't. It speeds up. However, your heart can skip beats, such as in Premature Ventricular Contractions.

Why Do We Still Shutdown Financial Systems for Weekends
|
5-day weeks are something that just a few decades ago was the norm. Most towns would essentially be closed on the weekend, especially Sunday . It's only relatively recently that 24 hour/7 day businesses have emerged, mostly out of need. They need to be open 7 days a week to be profitable. Some banks and services have moved that direction , but most have stayed put. Financial services have never had the need. In addition, because the other financial services they interact with to conduct business are also closed, it's basically impossible to be open on those "off days" since you can't get any work done.

Why did analogue TV tuners click from channel to channel while analogue radio tuners slid along a scale?
|
The number of TV channels available in a given area was relatively small, but they were often spread over a very large bandwidth. It was not technically possible to provide continuous tuning over such a wide band, and in any case the mostly empty band space would have provided a frustrating experience. The answer was the "turret tuner" which rotated a complete new set of tuned circuits into the RF end of the tuner at each click. The tuned circuits were on individual wafers which snapped into the tuner "turret", and an appropriate, pre-tuned set were provided for each area. By contrast, the fractional bandwidth of the AM radio channels was small, 550 kHz to 1750 kHz, or a 3.2:1 ratio, and many channels were full, particularly after dark, so continuous tuning was technically feasible, and made sense to the consumer. Even then, some early radios provided several pre-settable channels selected by buttons: this was done by mechanically shifting the tuning knob as the button was pressed. For FM the situation is even better: 88-108MHz, or a ratio of less than 1.3:1. A continuous tuning mechanism is simple, reliable, and cheap to makeMy Dad had an old 9" TV in the garage with a manual tuner that did not click. You could do some interesting things between channels. When you're off the main frequency range for a channel, there's a huge amount of distortion. UHF and VHF are on an entirely different frequency than AM/FM. They carry through object differently, and over distance differently. Also, picture takes more bandwidth to transmit than radio does, so the RF bands are largerBroadcast VHF stations were given a specific frequency for the video and audio carrier in megahertz which was assigned a number. For example, Channel 3 tuned the television to video carrier signal at 103.25 mHz and audio carrier 107.75 mHz. Even clicking tuners have a dial for fine tuning these frequencies. Radio frequencies on the allowed spectrum number in the hundreds. Nobody would want a radio with hundreds of buttons.

How is gps for self-driving cars accurate enough when my google gps totally craps out any time I'm in a mall plaza?
|
Self-driving cars use more than just GPS to navigate; they also use onboard cameras to identify the road, other vehicles, pedestrians, traffic lights, and other potentially relevant information. If they lose GPS signal, they continue going along what was the plotted route until the signal is regained. As the technology improves, they can also gather data on *where* GPS is likely to fail . In these instances, their navigation can plot more detailed courses in advance since the computer is anticipating a loss of satellite feed for a bit.Google self driving cars have about $75000 of custom equipment. They don't use GPS . They use a laser radar system to see their surroundings, which works through fog, smoke, dead of night.

Why is much more in taxes taken out of holiday bonuses?
|
So when your taxes get calculated, it's from a tax table. There are different tax tables based on pay frequency. So, if you are paid every two weeks, your employer consults the table for your pay amount, and the amount listed is what they have to withhold -- which is based on 26 times that pay amount. That works out pretty well until it comes to bonuses. See, they have to do exactly the same thing with the bonuses, but what happens is that since the check is more than usual, the tables estimate your taxes at a higher tax bracket. In any event, you'll get that money back when you file your taxes next year.

Why is this winter so warm (in the US at least)?
|
Because of La Nina. A current in the pacific ocean is cooler than normal, and that affects weather across North America.

Why the tallest skyscrapers are built only in Asia or North America but not in Europe?
|
The sky is significantly lower in Europe; there's really not enough height to build such huge skyscrapers.

Why does David Cameron want mandatory porn filters for UK internet users?
|
Information control. Australia's government tried to same thing a couple of years ago but it failed. Turned out that porn was just going to be the first step and then after that it was going to be everything the government didn't like. Whoever controls the information has the power. The idea is to get their foot in the door by saying it's about porn, specifically child porn and then after that you just quietly expand it to cover everything else.

Can anyone explain to me why it's called a traphouse. I know what a traphouse is, I just want to know the origin of the word.
|
Trap is slang for a place where drug dealers sell drugs. It could be a street corner, alley, or trap house.

What are MLM scams and what are examples of them?
|
The hallmark of a Multi-Level Marketing scam is that the emphasis and reward are heavily weighted against recruitment instead of the actual work of selling a product. If I hire you to sell vacuum cleaners door to door, and pay you based on your time/amount of sales, then it's a legit job. If instead I pay you relatively little for selling vacuums, but pay you very well for recruiting other sellers, then it's an MLM.

how are license plates numbers distributed?
|
Not sure if it's the same in Canada, but states in the U.S. print a bunch sequentially and send them to each local DMV. I'm not sure if they're assigned to an area DMV, or just whichever boxes get loaded. Either way, a specific area will tend to get a whole lot of certain sequences, and not many of others, and the state in general will have more too, since if they print a thousand starting with BNZR[-xxx], there's going to be a thousand more BNZR's than BNZS's, and ~~260,000~~ 676,000 more BN's than BO's.

Why do browsers and websites prompt you for saving your passwords if it is considered unsafe?
|
The Average Joe is unlikely to be "hacked", but very likely to forget the password to a site he hasn't used in a while. Browser password-saving is meant to be a convenience feature, not a security featureThe reason why it is considered "unsafe" is because it would allow anyone with access to your computer to be able to view your passwords. You can go into your browser's password manager and view plain text passwords easily. If you are the only person using your computer, or you are confident that no one will get on and view them, then there isn't a great risk involved in saving your passwords. Now, it is true that malware could gain access to these passwords. The file that holds then is encrypted, but the encryption isn't terribly hard to beat. Malware can definitely decrypt the file and read your passwords. So it isn't 100% secure.

Why does AM talk radio have such a disproportionately large amount of commercials compared to FM music stations?
|
Your FM station has sneaky ways of putting in advertising even though it might claim to have 55 minutes of music. It's advertising when the DJ comes on between songs and reminds you that they will be at a certain business tomorrow from 4 to 6 and they'll be giving away a certain item . It's advertising when in between songs, the DJ comes on and casually reminds you that the artist they are about to play has a concert coming up in a couple weeks and reminds you tickets are still available at a certain website . I could go on, but I'm sure you get the idea.

What is the overall goal/point of google deep dream?
|
Google deep dream was developed as a test of Google's image recognition software. Basically, they're running it backwards - rather than taking a picture of a dog, and asking the software "Is that a dog"; they take a random picture and ask the software "show me what looks like a dog". By seeing what the software draws, you can determine what characteristics it uses to determine a dog. For instance, back in the early days of image recognition, the department of defense thought they 'd trained a computer to recognize tanks in pictures. It turned out they 'd actually trained the tank to recognize sunny days, because the tank pictures were all taken on a sunny day, and the no-tank pictures on a cloudy day. Google deep dream, for instance, discovered the Google Image recognition thinks dumbbells have a human arm attached to them. Then they released it to the public because it makes cool pictures.

Why does it seem like most funerals in the US are open-casket?
|
Films and TV do open-casket because of course it is more dramatic and visually interesting. In the US, the family picks which they want.If you're talking about wakes/viewings , it is usually a religious thing. There is a huge Catholic population in the US, and an open casket is traditional.

Why is medicine dosage measured in half-life if half the medicine is still in the body?
|
It's not used to purely say when a patient has "0" of any drug in their system, it's more to help when giving "Top Up" doses, say you have a patient on Morphine that needs an extra dose, knowing the half life helps Doctors/Nurses decide of they're able to give them a slight dose if they need it. It's also used when calculating Antibiotic doses, as you need a minimum level in the body to acheive the desired effect, but balanced with potentially overdosing. For example, if 50mg is the minimum requirement, but each tablet is 100mg, with a one hour half life, the dosage would be: 100mg, wait an hour for it to drop to 50mg, another 100mg which takes it to 150mg, so the next hour/half life only takes it down to 75mg, so if the patient had another dose they would have 175mg in their body and so on. So, if this wasn't kept in check they would soon be potentially overdosing.

Teresa's daughter Riddle.
|
There's a couple of things you need to take away. We can work this out similar to how algebra work. "my daughter's mother" = "me, or my female partner" So now the riddle is "Teresa's daughter is me or my partner" If Teresa's daughter is me, I am Teresa's daughter If Teresa's daughter is my partner, I am Teresa's son in law Since none of the answers are "Son in law", the answer has to be "Daughter", or BYou're Teresa's daughter. "My daughter's mother" is another way of saying "myself" , because no-one else but you can be the mother of *your* daughter. So, by substitution, that means "Teresa's daughter is myself."

What keeps your skin cells in a human shape instead of them reproducing outwards indefinitely?
|
Oversimplified: Skin grows upward from a base layer - as you go further there's less and less blood supply, and cells aren't supported. The outer surface of your skin is substantially dead cells that form a protective layer. In the case of injury, other tissues are involved, and chemicals help signal where repair needs to happen. An abscence of those chemicals means repair can stop.

Why do people have to swear under oath? If they're willing to lie, they'll do it with or without the oath.
|
If you lie while under oath, you're guilty of [perjury], which is a felony in the United states, punishable by up to 5 years in prison. If you lie in your day-to-day life, you're just an asshole exercising the 1st Amendment.Lying is not inherently against the law. You are well within your civil rights to not tell the truth. However once you are under oath lying becomes a criminal matter. If you are caught lying under oath you can be found in contempt of court and you can be charged for perjury. Bill Clinton was almost impeached because of these very laws.I think it's more for the system wherein if they are found to be lying under oath, then they can be charged with perjury ). If they didn't swear under oath and they lied, they can't be charged with perjury.It's a formal declaration stating that you will tell the truth. It negate any chance that you could say "I didn't know I couldn't lie" That's why you swear on something you believe in I. E. Your faith in your god or you attest "*I do solemnly and sincerely declare and affirm that the evidence that I shall give, shall be the truth, the whole truth and nothing but the truth in the name of our sovereign lady Her Majesty Queen Elizabeth the Second of Great Britain, Northern Ireland and all dominions overseas*."I think swearing on a bible is ridiculous. As an atheist it holds as much sway as swearing on a roll of Charmin. But the Charmin is squeezable.

How do game cartridges and video game discs work?
|
Cartridges have memory chips inside that have the game code stored in them. When you insert the cartridge into the console, metal contacts in the console touch metal contacts on the game cartridge, and they can exchange data via electrical signals. The console loads the game off of the cartridge, and you play. Discs are covered with lots of microscopic pits that were imprinted on it when it was "pressed", and the console uses a laser to read the sequence of those pits, and turns that sequence into a digital signal. Cartridges load very fast, but the memory chips are relatively expensive and that limits how much data can feasibly be stored in them. Discs are very cheap to make, and hold a good amount of data, but cannot be read nearly as fast as cartridges.

How does adware work?
|
Adware is a piece of Internet connected software that is ether installed alongside something else you installed , displays ads as part of the interface or displays ads outside the program and doesn't make it clear Sometimes the program sends a request for an ad, or has ads pushed to it. These are a little less frightening, since they simply show you an ad. Other types may change your proxy settings and this proxy injects ads into your web pages and may also redirect your search engine to one they made to collect data for more advertising. This one is a great deal scarier, since all traffic is going through a remote computer you were not told it would be going through that could also record your browsing data as well as passwords for things like banks and stores. Adware itself is mostly annoying, causing your computer to slow down by using its resources to display ads and by.. Well displaying ads when you are trying to use it. The real danger is that this type of software often includes "backdoor" access to your computer, letting the authors install any other software they want for payment. This could mean installing botnet software to attack companies and governments, this could be viruses or malware like cryptolocker which encrypts your files and holds the key hostage or software that uses your Webcam to spy on you to use as blackmail or to upload to a porn site. In a security conscious environment, it's another program that could be hacked to gain entry to a system. Especially since most Adware isn't written very well. So if you don't want your mom to find pictures of you stroking your harbl, keep your system clean. This includes your phone, as it's really just another computer. No brand or OS is truly secure against malware, malware sneaks into the app store and Google play all the time and may take days or weeks to be found.

[Biology / botany] How is it possible that some plant species mimic the visual form of other beings, without being able to 'see'?
|
Random mutation. Sometimes the random mutation results in a look that slightly mimics some other look, which might give an advantage. For instance, something that looks slightly like a predator, might scare away a herbivore intent upon eating the plant. Thus, that plant survives to reproduce. Others that don't have the look, get eaten more regularly. So over time, more of the 'scary looking\' plant's progeny survive, relative to the 'tasty looking\' plant. So, it doesn't "Try" to look like something. It just accidentally does, but since it works, it gets reinforced by survival. However, some of the examples from the article you link are simply, as it alludes to, cases of pareidolia. It isn't mimicking something. We simply think it looks like it because our brains like to find patterns, and in some cases there is coincidental similarity.

How does voting for the president work?
|
Each state is allotted a certain number of votes, based on the number of congressional seats they have. For example, North Dakota, which has one representative and two senators, has three electoral votes. California, has 53 representative and two senators, for a total of 55 votes. For each electoral vote a state gets, the state assigns one delegate. Technically, the delegates can vote any way they want, but they will vote for whoever the state popular vote goes toward. Some states allow split votes, for example Nebraska in 2008 was split between McCain and Obama. McCain won the state, but per state laws Obama was given one delegate. Any candidate which receives a majority of the electoral votes shall become president. Historically the popular vote has meant pretty much nothing, however that is changing with some new laws which say that whichever way the popular vote goes, the state electoral votes will go, regardless of which way the state ACTUALLY votes. In other words, for example if Texas were to vote for Romney but Obama won the national popular vote, Texas's electoral votes would go for Obama instead. The biggest reason for keeping the electoral system is that it encourages candidates not to write off small states such as Nevada or Iowa. If it was only a popular vote, 99% of the election money would be spent in states like Illinois, California, NY and Texas. MOST OF THE TIME though, the popular vote lines up with the electoral vote. I.e., if you win the popular vote, you are extremely likely to win the electoral vote as well.

How do one-way windows actually work?
|
They are just heavily-tinted windows. What makes them one-way is that the room that's supposed to be visible is well-lit, and the room that's not supposed to be visible is dark . The window is actually just as visible in both directions. It's placement that makes it work.
|
Why is the last percent when charging your device the one that takes the most time?
|
In general, for charging batteries like lithium ion cells, there is a maximum safe voltage that shouldn't be exceeded . This generally means that as the charging cycle comes to a conclusion, the voltage of the charging circuit increases to a constant level, and because the cell voltage increases after that, the current flowing into the battery tapers off.

Is it possible to not get addicted to Cigarettes and Alcohol?
|
There's definitely a spectrum of people's physiological reaction to nicotine and how addictive it is. Some people just can take it or leave it. I was like you, a social smoker in college and for a few years after. I smoked when I drank, and a "heavy" day for me was maybe ten cigs, but during the week or when I went home for the summers I didn't smoke at all and never missed it. Obviously, you shouldn't smoke , but if it's been two years since you started, if you were going to get addicted at all I think you would have been by now.
|
Why is the hiring practice so much more difficult for minimum wage jobs than skilled labor?
|
I think part of it is weeding people out. The other part of it is that for skilled labor you usually have some other credentials that make the tests given at DQ pointless. If you have a bachelor's degree from an accredited institution, you should be able to pass a math and literacy test and have proven that you can at least follow university rules well enough to get a degree. That being said, I've seen some companies require ridiculous paperwork like you mentioned and I've seen other places hire minimum wage workers on the spot as soon as they've finished filling out an application.

Why are people with a lazy eye unable to perceive 3D in 3D films?
|
3D films used polarized light to create the effect. The footage is shot with 2 cameras, and projected through 2 projectors with different polarizing filters, one vertically polarized and the other horizontal. The 3D glasses are also filters, only allowing light of a vertical polarization to enter one eye, and light of a horizontal polarization to enter the other eye. The brain combines the images to form an image, and that's where the 3D effect comes together. ). From what little I know of Amblyopia , both eyes are still functional, but since the one eye is misaligned the brain ignores the image from it when forming the image in your brain. The two-camera effect is lost, since your brain is only 'seeing' the film from one of the cameras and ignoring the other one. You're essentially watching a standard one-camera production, the only difference being you're watching it through a polarizing filter.

How are professional sports statistics captured?
|
It's a bit of both. Traditionally stats are collected by the official statisticians - there is usually a team of them For instance in hockey one person is responsible for tracking when each player gets onto the ice and when each player leaves the ice, for the purposes of tracking time on ice. All of the traditional baseball stats can be gleaned from the official scorer's report. There are more advanced statistics being tracked, like in baseball they are tracking things like launch angles and exit velocities for batted balls, route efficiency for fielders running towards fly balls, etc. That stuff is all computerized

why are trans fats not completely banned by the FDA?
|
Several ostensible reasons, such as the fact that trans fats are naturally occurring in some levels in many meat and dairy products, so banning them would mean banning those meats or diary items, which would be both difficult and cause a large uproar from consumers. Also, the federal government doesn't *really* have the authority to do so. They have had to jump through many convoluted hoops and make up laws by the seat of their pants to get things like marijuana made illegal, mostly because banning the possession of things like plants and naturally occurring compounds isn't actually an authority given to the federal government by the Constitution. They have gotten away with it by stretching some Constitutional provisions like the interstate commerce clause to claim that anything that *might* be transferred across state lines, or even something of which it could not be discerned if it crossed state lines or not is presumed to have done so, in order to give themselves the authority to ban things wholesale for the entire country. There is a reason why banning alcohol took a Constitutional amendment a century ago. Back then, things like what the federal government could and could not do were more well understood and taken seriously. Now, not so much. But the primary reason is much more simple. There is a hell of a lot of money in multi national companies, the same companies that sell hundreds of billions of dollars in products that contain trans fats. Those companies have a vested interest in making sure they're not banned, and have their lobbyists make that abundantly clear to their paid lawmakers.Because some transfats occur naturally without intentional action although most are unnatural or added artifically. Banning a natural substance is the height of stupidity & political hubris.

Why do people think that blacking out their eyes in pictures protects their identity?
|
Eyes presumably show the most emotion / personality etc of any body part, so we're most likely to remember those, if we see them again. Also, who blacks out their own eyes..? It's usually done by others to protect the identity of someone.Good question. I was going to answer "so we don't remember them" but I remembered that we remember people like Stevie Wonder and we 've never seen his eyes.I guess it gives the sense of privacy and at the same time not ruin the photo by having a big blur spot in it. if someone were to try to find out who the person is with just the eyes area blackened, it wouldn't be difficult at all. When keeping the identity of a person secret is critical, then the whole head is blurredeyes give more of an individualized experience then any other part of the body, especially for ease of concealment. People are better concealed when their all fuzzed out and their voices are changed, but the blacking out of the eyes is a quick way to add anonymityIt works because humans make eye contact first, and it is where we look most of the time. It also takes out all or part of the nose. The other big features that are left are the chin, ears, lips, and hair. Generally not enough to know for sure unless you are doing a side by side. But you can still get a feeling for who it is.

why do dry erase markers erase themselves if you color over a line you already drew?
|
The pigment in the marker is dissolved in alcohol. The alcohol evaporates after you write with the marker and expose it to air, leaving the pigment as a dry, solid layer . This is why you can't write with dried-out markers. But if you write over the pigment with the marker, it dissolves again in the alcohol you're adding.

Bohr's Theory of the Hydrogen Atom

Basically, the atom was understood like a solar system. Electrons orbiting the nucleus. Bohr suggested that the electrons could only be in very specific orbits and light was emitted when it went from a high to a lower orbit and light was absorbed when it went from a lower to a higher.
|
why do musicals play a medley of the music in the musical at the beginning before things start?
|
Traditionally the Overture introduces the musical themes used later in a piece like an opera. The Finale will recap them at the end. It's a little like the essay structure Introduction - Body - ConclusionTo add, the orchestra often gets very little recognition for their hard work during the actual show because the onstage performers get the attention. The overture and finale are a chance to recognize the hard work of the orchestra members.

Why does rubbing your eyes feel so good? And is it bad for your eyes/vision?
|
Optometry student here. I suspect that rubbing your eyes could feel good for many reasons. Allergies is the obvious one. But usually it's because people tend to feel like they have "tired" eyes, especially at the end of the day, which for optometrists that translates into "dry eyes" much of time. Rubbing your eyelids can stimulate meibomian glands to help secrete oils that normally cover your tear film layer. This keeps your tears from evaporating = less dry eye and increased comfort. Rubbing your eyes may also feel good because you are "massaging" the eyelid muscles and purging them of lactic acid . I have nothing that supports this - it is only my best guess. Is it bad? Generally no because the eye can take a lot more pressure than people think - your cornea is only 0.5mm thick and to think that it rarely ever gets seriously damaged is astounding. Some theories exists that people rubbing their eyes a lot can be a risk factor for developing a pretty miserable condition called keratoconus, in which the cornea becomes misshapen and may require a transplant after a few decades with the condition. But this might actually be BECAUSE they already have the early stage of this condition and their eyes are irritated from the disease, and so they rub them. The jury is still outI have no idea why rubbing your eyes feels good, but if you rub hard and long enough , you can induce a condition called [keratoconus], which is a deformity of the cornea. Keratoconus can significantly distort your vision. Additionally, rubbing your eyes can lead to an increase in intraocular pressure.Run your fingers firmly along your eyebrows, you'll notice there is an indentation roughly above the center of your eyes on the bony ridge of your eye sockets. This is where a nerve goes into your skull. When you have a headache, press on these indentations and it will feel wonderful.

Why do people advise against using the 1st check in a checkbook?

It's a paper scheme obviously! They just wanna sell us more paper! Just kidding I've never had anyone tell me that before. I always use the first check and nothing bad has happened to me. I'm posting here to profile this, so that I can see if I'm being stupid.

Why can't we use spectrometry to reverse engineer the Coca Cola secret formula?
|
At most that will tell you whats in the can and the approximate amounts. That information is already printed on the can. It wont tell you the process that was used to mix the ingredients.* knowing the ingredients is very different than knowing how to combine those ingredients into a final product the precise ingredients, while not printed on the can, and widely known and are make available for people with allergies and dietary restrictions* they secret to a product like Coke isn't really the ingredients, or even how their a prepared the secret is producing it economically on an international scale while maintaining consistency and quality

Why is violence in video games acceptable, but sexual violence is an extreme taboo?
|
Everyone is used to violence and in some cases it’s perfectly acceptable to use it . There are no cases where sexual violence would be acceptable, howeverMost games present violence in semi-acceptable situations, like war, self defense, or killing evil space goblins. Even when it is clearly criminal, the game play is much the same villain or agent of justice, you are still mostly running around killing hordes of nameless enemies. Non-consensual sexual violence is reviled in just about any conceivable situation.

Why do jokes make us laugh?

A good explanation I have heard is that most jokes *subvert our expectations*. In other words, they lead us to start following a trail of thought in a certain direction, then BAM! we are forced to think in a totally different way suddenly. The element of surprise makes us laugh. Here's a good article about jokes: _URL_0_

How do birds know which direction to fly when they head south for winter?
|
Many birds have a sense of magnetic field that allows them to know direction and travel to the right place. Many sea turtles also have that sense. Many birds also have a sense of barometric pressure as well, which is why you can often birds leaving an area before a storm.Birds can sense the Earth's magnetic field. It's just a sense that they have that humans don't. It's just hearing or smelling to them.

How does a molecular sieve dry a sorbent
|
The principle is called adsorption. Molecular seive is a material with tiny little pores, like activated charcoal. These pores are like the dimples on a golf ball but tiny, nanometers in size. You make it work by selecting a desiccant with a pore size that matches the size of the molecules you want to absorb. The pores 'catch' and hold onto the molecules, adsorping them. The forces involved could be van der waahls force, covalent bonds, or just static electricity. Some molecular sieves can be heated to then release the adsorbate and reuse the sieve.

In what circumstances does a president sign a bill while Congress is in session?
|
If in 10 days the president doesn't sign a bill and Congress is still in session then it becomes a law just like you said. In that case then, the president has three options. They are different in not just whether the bill becomes a law but also in what they mean. * The president can obviously veto a law meaning he is strongly saying it shouldn't be a law. As long as congress doesn't have enough support to over turn it, that's that. * The president can sign it meaning he really does want it to be a law. * The president can not sign it. It still becomes a law but the president doesn't have to show that he like the law. It's a statement more than anything else. Maybe he knows that he will be overturned if he vetos it , maybe it's for another reason, but whatever the underlying reasons it's a way for him to basically say "I don't like this enough to put my name on it but I can't/won't stop it."

What does a movie/TV producer actually do?
|
For film, producers oversee the entire production of the film. First, they have to acquire the rights to create the film. Then, they have to find someone to write the script . Then they have to hire the director to actually create the film, along with hiring the casting director, sound people, actors, etc. Some of these decisions are done in conjunction with the director, while others are not. In short, the producers are in charge of the business of making the film.A Producer's role is to basically bring the whole project together so it can be made; once a script has been given the go-ahead by executives, the Producers of the show/movie have to hire the director, the writing team, the cast, cameramen and any other essential crew members. They also have to organise filming locations, transporting the crew to the location ,make sure they are allowed to film in the area, hire wardrobe designers and stylists, etc.

Why does color affect heat absorption?
|
It's not color that affect heat absorption. It's the physical propriety of material that absorb different wavelenght of light. So if a material absord all visible wavelength of light it will appear black because it doesn't reflect back light into our eyes. Alternatively, something white is made of something that reflect all the visible light back so we see the color white. Something that absorb more wavelength will absorb more energy from that light, which will become heat.Color is a *symptom* of light absorption. Items appear light if they are reflecting light away. Items appear dark if they are absorbing light -- which will of course mean they are going to warm up.

Why is gambling is considered a dangerous vice?
|
Okay, you're asking two questions here. 1. Why is gambling considered a dangerous vice? Because some people have the tendency to become addicted to gambling and it can engulf their entire life. They will spend every last dime to chase that feeling of winning. In the end though, the house always wins and that's why it's a business. 2. Why can you join the army but not gamble because of your age? Well, it depends on the state you live in, and also the type of gambling. Some states, depending on the form of gambling do allow gambling at 18. The other answer is outdated laws or laws that make zero sense. You're correct that in some place you may not be allowed to gamble because of your age, but you can enlist to go and possibly die. You are also not allowed to drink or smoke . One can go and risk their life for country, but god forbid they have a beer after work.

if a teenager can be charged with child pornography for having pictures of themselves, why can't they be charged with sexual assault when they masturbate?
|
Because they've given consent to it as a sexual act. However, if they somehow did it against their own will, then they could potentially sue themselves. Even under the age of consent, they are doing it to themselves. Plus, the only people who could sue in the name of their kid would be the parents. But again, the kid is the one doing it to themselves. Child pornography is illegal no matter if you give consent to someone or yourself, or not.

Stephen Hawking theory that information can be lost from the universe when black holes evaporate away
|
Well, it's wrong because of the word evaporate. When water evaporates, the information of water is not gone. It's transferred to another state of matter. It's only lost in the sense you can't get that cube of ice back, in exactly the way it was frozen, even if you could somehow capture all the water molecules. Honestly, I'm not smart enough to understand how Hawking Radiation works, using it's quantum mumbo jumbo. The only way I can reason it, is to imagine its higher frequency means it isn't as bendable. Like the difference between a tree branch and a steel beam. In that rationale, then gamma rays escape the hole because it can resist the force to bend back upon itself.

How do they get pure oxygen into oxygen bottles?
|
Do you mean tanks of compressed oxygen? There's a few different methods, depending on the purity of gas required. A common method is cryogenic distillation. Basically you make ambient air so cold that it liquifies, then raise the temperature of that liquid just to the boiling point of oxygen. The oxygen gas will boil off from the rest of the liquified gasses and you can capture and compress it to produce pure oxygen.

Why do men and women have separate restrooms?
|
It is for comfortability. Many people feel uncomfortable with members of the opposite sex around while they are doing their business. It is that simpleEasy, it's so when you are out to eat with your wife and baby, and the baby needs changing, you can shrug and say, "sorry, there's no changing table in the men's room, you'll have to take care of that"I'm going with, maybe. As the world is now, no. Separation of these two "zones" is so commonplace now. As a female you wouldn't want to walk in to a guy with his dong out pissing. As a guy, you wouldn't want to walk in to tampons and all stalls. But I see where you are coming from. In a house we all use 1 bathroom. But we do it solo. It's somehow different in groups. In the future when we have body scanning technology that customize each "stall" to that gender. Yeah. One huge room will do it.

How do fuel cells in the Voyager 1 & 2 last for 80+ years, yet the fuel in my car won't last a week?
|
They use these:_URL_0_ They're great if you need a power source that lasts for years and years and years and you only need to power a radio, a computer and a few other gadgets on a satellite, but they're not great when you need lots of power to drive a car with.

Why do sites choose to go with 'smart' or 'curated' lists (Hulu / Instagram) versus pure chronological or user chosen lists? (Netflix / Twitter)?
|
Essentially it just keeps you coming back for more. While you could cycle through Hulu alphabetically, there's a chance you don't want to watch 75% of what they have. You don't know exactly what you want to watch, but it's none of that garbage they're tossin at ya. You become fatigued and think, "man, am I really just gonna watch Seinfeld again? Hulu doesn't have any good stuff". You then search random stuff and wouldn't ya know it, they don't have any of that stuff! Over time this makes you think about your entertainment options and decide, Hulu isn't going to have anything, maybe I'll check out Netflix. This is bad for Hulu. So, they track you and find out what you like. The science isn't perfect yet but they can probably guess what you want to watch before you do. This way, every time you go into the app, they're hiding all the options that you have no interest in, and all the stuff you like. This makes you come back more often because you're not wading through a bunch of crap. It feels tailored to you, without you even thinking about it. As far as "posts you may have missed" or "what's new/trending", it may be content they wish to promote, or as simple as advertising to you that it's not the same old stuff, there's a bunch of shiny new media to take in. You take in this new media, believe the app is providing you benefits, and for sites like IG or Twitter, you are branching out and following new people or sharing posts from accounts you didn't know, which keeps business booming. Sorry for the wall of text, and I'm by no means an expert, but I hope this answered your question. It's tangentially related to what I study, so I took an off the top whack at it.

Random flashes of light when my eyes are closed at night after going to bed.
|
You might want to get that checked out with an Opthalmologist. Seeing bright flashes of light inside your eyes is usually due to the retinal cells getting stimulated by movement or traction. Not keen on scare mongering, but in rare situations it can be a precursor to retinal detachment.do you often hear a bang or a shock at the same time, because it sounds like it might be caused by 'exploding head syndrome'. A harmless condition which occurs when people are trying to fall asleep

Why are keyboards organized in a QWERTY format instead of alphabetically?
|
Because of typerwriters. Back in the old days, the physical keys of the typewriter's keyboard were connected by steel prongs or wires to their corresponding letter-striker thingie. Anyways, if you typed too quickly, neighboring keys had a tendency to get tangled up with each other. Thus the QWERTY design was made to try and separate the more commonly used letters to avoid this problem. Since typing is a learned skill, its too ingrained in the general populace to try and change it on a wide-scale.Before computers people typed on typewriters. They used a simple ABCDEF etc keyboard, but frequently used letters where close by and this caused frequent jamming. Someone came up with the QWERTY keyboard that spaced the frequent letters apart, and this cut down on jamming. Everyone thus got used to the new QWERTY standard. computers came around and since everyone could already type on a QWERTY layout they just used it for keyboards. You can buy alphabetical and other odd layout keyboards if you want.

Has Hacking Proven Password Encryption A Failure?
|
The hacked databases that have gotten huge media attention have not used advanced algorithms to protect the passwords. Linkedin used unsalted SHA-1, Adobe used DES encryption , myspace used unsalted SHA-1 of the first 10 characters in lowercase, Badoo used unsalted MD-5, etc. We even know about a lot of sites that store the password in plain text. The only big breaches that have shown good password routines have been Dropbox with half in salted SHA-1 and half in Bcrypt and tumblr with salted SHA-1. Hacking have not shown any faults in passwords. It have uncovered some dangers in bad password storing practices, bad passwords and the dangers of using a single factor authentication. You could unlock similar faults with any authentication system no matter the way they authenticate. Passwords are safe but make sure you use a good password and use a password database to have strong unique password for each service. Where available use two factor authentification. If you are designing an authentification system make sure you store the passwords safely, allow the users to set complicated passwords and make two factor authentification available.If someone wants the data badly enough, they will get it; however, that doesn't make it pointless to make it as difficult and as inefficient as possible to get it. Unless this is a very deliberate and targeted attack, people aren't going to waste time on anything but low-hanging fruit. Just like how you lock your doors to your house. It's not going to keep someone really dedicated from getting in, but it'll stop the random opportunist from just walking in and taking your stuff.

How does the fridge stop your food from going bad?
|
Food going bad is a result of microorganisms. Most of them grow better in warm temperatures; a fridge cooling the food slows down their reproduction rate so the food will be edible longer.

how liquid gets into your bladder, and why it seems faster when you're drinking beer
|
When you drink something, the liquid is absorbed by various parts of your digestive tract, primarily in the intestines. It then enters your blood. Excess water is removed from the blood with the Kidneys, which also remove other bad stuff at the same time. All this stuff they remove from your blood ends up in the bladder. Alcohol is a diuretic; It reduces the release of [a hormone] your body uses to regulate how much water there is in your blood. This makes your Kidneys think you have more water in your blood than you actually do, so they try to remove more of itAlcohol suppresses Anti-Diuretic Hormone, therefore the two-edged sword is greater amounts of liquid in your system, and the alcohol keeps the body from retaining it; makes you pee, a lot.

Why is it called a Chinese Fire Drill?
|
Copied from Wikipedia, because it explains it in fairly simple terms: “The term goes back to the early 1900s, and is alleged to have originated when a ship run by British officers and a Chinese crew practiced a fire drill for a fire in the engine room. The bucket brigade drew water from the starboard side, took it to the engine room, and poured it onto the \'fire\'. To prevent flooding, a separate crew hauled the accumulated water from the engine room, up to the main deck and heaved the water over the port side. The drill had previously gone according to plan until the orders became confused in translation. The bucket brigade began to draw the water from the starboard side, run over to the port side and then throw the water overboard, bypassing the engine room completely.[2] Additionally, the term is documented to have been used in the U.S. Marine Corps during World War II, where it was often expressed in the phrase "as screwed up as a Chinese fire drill".[3] It was also commonly used by Americans during the Korean War and the Vietnam War.[4] Historians trace Westerners\' use of the word Chinese to denote "confusion" and "incomprehensibility" to the earliest contacts between Europeans and Chinese people in the 1600s, and attribute it to Europeans\' inability to understand and appreciate China's radically different culture and world view.[5] In his 1989 Dictionary of Invective, British editor Hugh Rawson lists 16 phrases that use the word Chinese to denote "incompetence, fraud and disorganization".[6]”

Why can't I remember being a baby?
|
Cognitive psychology student here: To put it simply, you don't have the mechanisms that allow you to store and recall memories until you're around 3 1/2 years. Until that, you have what's called childhood amnesia. From that moment on, when you're 7-10 years old, you go through a period that's called reminiscence bump, when the majority of your childhood memories begin to form and stay with you all your life. However, in extreme cases it has been proved that children under three years old can create and store that kind of autobiographic memory. I don't know how much of this is suitable for a five year old, but i think you can understand. Cheers!

What exactly are hashtags and how do they work?
|
Well, if reddit worked like twitter, and I wrote **"#PutinFartsOnABear,"** then the hashtagged word would act like a link, showing you all the other submissions that include that hashtag. It also helps track and catalog what people's tweets or facebook posts are about, and so you can see if a topic is "trending" greatly or notNerd_so_hard covers how they work once #Hashtags were formalised and incorporated into Twitter . Originally, the "#" helped create unique terms that could be easily searched, and to separate intentional uses of a term from accidental or incidental uses. For example, you want to find tweets about AIDS. A search for "AIDS" would turn up all kinds of uses of the word, in the context of helping, the disease, or even as parts of other words . "#AIDS", meanwhile, will only be used by posters categorising their tweet as being about the disease. An analogy would be using CTRL-F to search a large document for a word. Maybe it's a short word like "Mom" and is going to capture a lot of irrelevant results , so you search for "mom" with a space after it or before it, or followed by a period or comma - this is what the #hashtag helped you do.There are popular ones, say you're touring with a band; you may use #tourlife on all your photos. If you click on that hashtag, it will show a whole bunch of photos taken by people just like you who have tagged their posts with #tourlife. This entire concept falls apart when people of low intelligence or understanding of anything #tag #their #sunday #post #with #meaningless and #boring ##'s

Where did the myth that police have to tell you they're police if you ask them come from?
|
Police are allowed to commit a very large variety of activities that would otherwise be considered crimes. The need to maintain cover is huge. They can move drugs, smuggle them. Launder money, as long as they are doing it within the scope of their undercover operation. They can do drugs if it's required to maintain cover. The moment it is something outside the scope of the operation it becomes illegal for them to do it. About the only thing they can't do is cause permanent injury, kill someone, or cause large scale damage like burning a place down.

What is the "Faerie" lifestyle?
|
Bro from one man to another, bail. You're heading down a rabbit hole you don't want to go down. To answer your question, your friend is what is known as an "otherkin". Popular among Tumblr users, it's a term used to describe people who really truly believe they are not human, at least on the inside. Most people use it for animals, but really anything goes. Snowflake syndrome, that's all it really is.

How do LiDAR sensors work? Wouldn't they just be overwhelmed by all the natural light?
|
They use very bright IR lasers, which you can't see because they're outside the visible spectrum. The LIDAR can easily see the spot from its laser - it's no different than using a [bright laser pointer]. Combine that with an extremely [aggressive filter] on the lens and it's not much of a problem. Edit: there are other tricks you can do as well. For example, you can gate the sensor, such that only returns in a certain window are accepted . Or you could code the laser pulses, so only returns which match the signature of the laser pulses are accepted. Either way, visibility isn't much of an issue.

Why are no countries boycotting the 2022 FIFA World Cup despite the corruption and even though people were exploited and died building the stadiums?
|
Because everyone still loves the World Cup. Also, this: > people were exploited and died building the stadiums? is false. People *are still being exploited and dying*, because the stadiums won't be complete for another six years. The death toll of the 2022 World Cup is expected to top 500,000 Qatar slaves.

Why is it some learn faster than others by reading?
|
The point of schooling is not "to learn things" but "to learn how to learn." When you go out and find a job, you'll find that most of the content you learned in school would not apply at all. You will have to use your skill in learning new things to adapt to all the new content you need to absorb. That said, the guy in your class probably has mastered the most efficient way of learning for him. He can probably organize all the content in the text in his mind or on paper while he is reading. But for you, it might not work the same way. Every person has a different type of learning style and it takes a lot of trial and error to discover it. I, myself, learn very well when I am taking notes during a lecture because it mentally scribes all the content to my brain. Other people study well in groups by bouncing concepts back and forth to reinforce them. Some other people can write all the things they learned in the form of questions so they can quiz themselves later on. There are multiple ways of learning but some will work better than others for you. Remember, don't just study hard, study smart. This means to be the most efficient with your study so try new studying techniques until you find something that just clicks. Once you do, then you can be "that guy" in class that doesn't appear to study hard .some people take in things better when they read, others when they hear it, yet others when they participate in it actively somehow. it's different for everyone. most people are a combination of all of the above. interest in the subject makes a big difference as well.

Why has The Avengers movie been released in several major countries before its release in the United States?
|
So far as I know, it's to reduce piracy. Countries like NZ often have to wait to see movies months after they screen in the US and this provides a window for piracy that can't be closed by lawyers. If they release movies in non-US countries first then they only have to worry about piracy in the US and that's a scenario in which their lawyers are actually useful.

What is a Physician Assistant (PA) compared to a doctor or nurse?
|
A PA, or a Nurse-Practitioner is somewhere between a nurse and a doctor in terms of training and education. For a lot of the things you typically go see a doctor for - strep throat, cold/flu, ear/sinus infection, pink eye, bronchitis, etc - you really don't need someone with 10 years of medical training to diagnose and treat. It's more efficient and cost-effective to use someone with less training do deal with these "entry-level" type problems, while the doctor can focus on more specialized or complex cases. In many states PA/NP can only practice under the supervision of a physician. Laws may also limit what types of treatment they can perform and what medications they can prescribe.

When we have those dreams that we're falling, why does it feel like we actually fall into the bed?
|
It's because when you're muscles are relaxed, sometimes the brain messes up and thinks that relaxed muscles mean you're falling instead of resting", 'I know this is odd, but the sensation of falling is all in your head. A rock falling doesn't experience that "dropped" feeling, or the feeling in your stomach and entire body. Animals with a nervous system are being told they're falling by the nervous system so they may survive it . Your nervous system uses information it's receiving to inform your brain of what's happening. Humans don't want to fall, nor did our genetic ancestors. In your dreams, your brain can think that's what's actually happening. The same reason people wake up yelling, scared, sweating, and the like. Your muscles are relaxed and sort of "cut off" so that you don't move that much in your sleep. Or why when you wake up, you can sometimes just assume what you dreamed was reality, before realizing "oh, it was all a dream. I don't have a test today and the monsters aren't after me. Or real." People who have vertigo or other similar conditions experience similar things, even though they aren't moving. When you drink a lot, it can often feel like the room is spinning . The takeaway is that the sensation of "falling" or any "feeling" is designed for you, but it doesn't always happen under the right conditions. Your brain can believe a lot of stuff, so the act of falling isn't necessary for the sensation of doing it.
