Why Time Warner Cable customers can't access HBO Go (when Time Warner owns HBO)?
|
Time Warner owns HBO, but Time Warner [no longer owns] Time Warner Cable. HBO GO is offered free to cable providers who carry HBO. The main problem is that cable providers have to develop systems to authenticate customers and make sure they subscribe to HBO. Then they have to create links to HBO GOs site such that only HBO subscribers are allowed in. Until your ISP/Cable provider has such systems in place , HBO GO will not be available to you. IIRC, wholesale HBO costs around $8 or $9 per subscriber.

If there is lead in solder are solder joints dangerous to touch?
|
No, it is not toxic to touch solid lead. Lead poisoning results from **ingestion**, **inhalation** or **dermal contact** **TL;DR**: *No, but wash your hands afterward anyway.* You wouldn't want to eat it, but generally the solder locks most of it away, and even if is some "loose" lead, it has to be ingested for it to affect you. It's recommended that you wash your hands with soap after handling much of though, but if you're going to be handling a lot of it, such as if you're removing old piping or other soldered metalworks, one would hope you 'd do that anyway. Even if you're actively soldering and handling a spool of the stuff, you're not going to get lead out of it - soldering irons don't get hot enough to vaporize any lead. That being said, you shouldn't breathe the fumes anyway as they can cause other problemsSolder joints on pretty much every electronic product are lead free for about 10 years ). If you work on older solder joints remember to wash your hands afterwards and you should be good.

How do cops detain and handcuff somebody with one arm?
|
They either: * cuff their hand to their belt* get a belly chain* if they appear to be of little threat, let them go uncuffed', "Cop here; Handcuff to the belt. If no belt, use a rip-hobble as a belt and handcuff to that.There are a variety of restraint devices that can disable a one armed person . For example. one handcuff to the good wrist and the other to an ankle.

With all the breakthroughts we've seen in cell phone and car batteries why hasn't the household batteries like AA, AAA, D's life been extended as well?
|
They use different chemistries. Your standard batteries are alkaline cells. They aren't that dangerous in the sense that they don't explode but because of that they are less energy dense. Most modern phones and electric cars use lithium ion cells. These are way more energy dense but have the tendency to become very hot or even explode when over discharged, punctured or short circuited. This isn't a problem because the devices they are used in have circuitry that closely monitors the battery and shuts off the device when something goes wrong. Lithium ion batteries are also more expensive than standard lithium batteries. Standard gas cars use a lead acid battery to start the motor and keep the lights on. While lead acid batteries are powerful they are also very heavy and big. TL:DR different batteries have different trade offs", 'In addition to that answer, it's important to note that batteries haven't advanced very far. Your phone components just get smaller and smaller in order to make space for the battery. My Macbook Air is like 85% battery. Elon Musk said earlier that they are approaching the theoretical limit of current battery technology. It's the one aspect of communications tech that has not followed Moore's Law, and has stubbornly refused to. There have been incremental improvements and economies of scale to lower cost, but the actual theoretical design of energy storage? Ehn. So all the rest of our tech, from Google Android using "Doze" to sip battery to chip design to screen tech to software, is designed to optimize the limited battery we have. When a new device claims longer battery life, it's either software/design using less power, or the same design is now smaller which means room for a bigger battery.Some of the rechargeable versions of those batteries have significantly more capacity than some of the non-rechargeable versions, and they're also rechargeable. Edit: There are alkaline versions of those batteries with enormous capacities as well.

Why are people Shy or not shy?
|
It's just a difference if how you approach situations. I 've often been called shy when I'm first introduced to someone, but the thing most people fail to realize is that the reason I'm not more "out there" is because I don't really speak unless I have something to say. Unless I'm continuing a conversation previous to the introduction, I will wait until more convenient time to join in the new conversation. I'm not shy; I just don't want to be in your face. It annoys me when people do it to me, so why would I do it to you?First of all I just want to clear this up. People are not just ‘shy’. Are you shy around your family and best friend? Probably not. You might be shy around strangers or large group but that narrows it down – you’re shy in certain situations. So rather than taring the entire idea with ‘you’re shy because you’re a shy person’ lets actually look at a common situation where you might feel shyThis can have to do with neurological wiring and early childhood experiences. If you 've learned not to trust people due to early experiences, you may become "shy", and the opposite also seems to be true. Another explanation centers on a person's "cognitive arousal level". Essentially, some people's brains and nervous systems are more sensitive than others\', so casual encounters may seem more or less overwhelming and anxiety-inducing to them.

How does the "neutral" wire work in cars?
|
In the car, you're dealing with DC, in the house it's AC. The wavy voltage you get in AC is the difference between the "live" and "neutral" lines, but importantly, neutral is not ground. It's usually relatively close, though. The earth line is the emergency exit for power when it's all gone wrong, and is very handy when you're dealing with quite a lot of power - the sort that gives shocks and causes damage to people if it's all going wrong. The power in your house can do that, and the power in your car doesn't. There's 2 exceptions - the starter motor and HID headlights, but for accessories - the radio and the radar detector, you're safe. It's only 12 volts and not a lot of current. So, the power comes in from the red wire, the one you put the fuse on, and it goes out via the black wire, to the body of the car. The car body is connected to the negative terminal on the battery, so any bare metal on a car will work for the negative wire to make your circuitthe ground is the frame of your car, which is in contact with your engine block, which is wired to one end of your battery. basically anything metal in your car that is grounded IS the other "wire".

what's the difference in the technology between a pair of beats ear buds and a pair from gas station?

What exactly happens when you get that heart wrenching feeling in your chest, like when that Semi truck almost ran me off the road today
|
[Adrenaline baby] > Adrenaline is a hormone produced by the adrenal glands during high stress or exciting situations. This powerful hormone is part of the human body's acute stress response system, also called the "fight or flight" response. It works by stimulating the heart rate, contracting blood vessels, and dilating air passages, all of which work to increase blood flow to the muscles and oxygen to the lungs. Additionally, it is used as a medical treatment for some potentially life-threatening conditions including anaphylactic shock. In the US, the medical community largely refers to this hormone as epinephrine, although the two terms may be used interchangeably. > The adrenal glands are found directly above the kidneys in the human body, and are roughly 3 inches in length. Adrenaline is one of several hormones produced by these glands. Along with norepinephrine and dopamine, it is a catecholamine, which is a group of hormones released in response to stress. These three hormones react with various body tissues, preparing the body to react physically to the stress causing situation.

What happens to an unborn baby that is going to have a nut allergy (or any other type of allergy) when the mother consumes nuts?
|
It doesn't hurt the child because the mother is processing the food for the child. You mostly want to avoid things that get into the blood or can be passed through the placenta to the baby and have a harmful impact . Studies have actually shown that mothers who eat nuts during pregnancy have children who are less likely to be allergic to nuts.

When an actor drops weight (like Chris Hemsworth, from "Thor" to "In the Heart of the Sea"), where does all the muscle go?
|
Most of the time it is lighting and camera tricks that make them look as big as they do. Now that doesn't mean they don't have to put on size when playing certain roles it just means they don't put on as much as what it seems. As for your question, the body uses the muscle for energy same as fat in someone losing fat weight. Scientifically it is breathed out after it makes the entire chemical breakdown. _URL_0_

Why do doctors and dentists seem want to get patients out of the recovery room and home so quickly after a surgery?
|
Hospitals are not a place where you want to stay but need to stay. You're surrounded by sick people and the bacteria there are much more dangerous and immune than outside of hospitals. You want to get out of there as soon as possible. Sure it sucks to puke at home, but doing so at a hospital is of no advantage to you, since it's nothing a doctor can or needs to help you with. An unnecessarily long stay also causes extra financial and time costs and takes up space that people in actual need could use.The above comments are true. However I 'd like to add that there is genuine research that patients who go home to recover perform better across many indicators. Use google scholar to look into surgery outcomes, there are lots of studies on this. People are more comfortable in their "home" environment, less stressors etc. however this is not necessary across the board - it depends on what that home environment looks like, if they have someone/ services to support them in recovery etcIt costs money to house a patient, there are other patients that are waiting A number of factors, but it ultimately comes down to the fact that the hospital needs to make money, and patients bring that money.

Why do people often lie for seemingly no reason at all?
|
This is difficult to answer with fact, and is more based in personal experience and observation. People with philosophy major/minors would be better suited to describe the more complex parts of the human for this one. However here is my 2 cents. As someone who is a compulsive liar it stemmed from childhood. Often I would get in far more trouble for telling the truth then I would for lying. Both long-run and immediate. Like many habits lying produces dopamine, causing me to feel rewarded for lying. However, guilt usually follows after. It's hard to break this habit as it makes me feel safe and incontrol of the situation while very rarely resulting in a bad outcome. Another part stems from our flight or fight response. Lying is the flight response kicking in. Humans are very much animals when it comes to our instincts - we don't want to put ourselves in the way of harm. We view social situations in a lot of the same ways as we view danger and will act differently depending on the level of stress. Lying is a sense of control and lets us not be vulnerable.

what are the meanings behind the " & co.", "unlimited", "limited" "incorporated" etc. additions to different company names?
|
Some countries, and some states within countries, have requirements about naming companies which may require them to state the type of entity the company is. This is a holdover from a time when corporations had to be chartered for a specific purpose. They were not supposed to do anything outside of that chartered purpose. That's where the use of "Limited", or the abbreviation "Ltd" arose. Today in most parts of the world corporations are not limited. They are typically organized with a charter that says they can engage in any activity their directors and shareholders decide they want to engage in. These entities are usually identified as "Corporation", or "Incorporated", or the abbreviations "Corp" or "Inc". There are a few other things you might see: "LLC" - a Limited Liability Company, which works almost exactly like a corporation but has some different taxation rules. "LLP" - a Limited Liability Partnership, which are common for things like legal and medical practices, and provide some insulation between the partners for the other partner's liabilities. "Partners" or "Partnership" - a company owned by two or more people who jointly share the liabilities of the entity. " & Co" - Means "and company" usually indicates a family-owned or sole proprietor doing business with associates who don't share liability. Same with " & Sons" or " & Daughters", etc. Different countries often have different names and abbreviations for joint stock limited liability corporations. Examples: aG or GmbH: GermanyCia: BrazilCie, SA: Franceplc: UKFurther to this, A PLC is a Public Limited Company, these have different requirements for setup. A Private company can be set up without major restrictions to the number of shares,shareholders or start up capital required. However, a Public Company requires more than 2 shareholders, a registered company secretary and at least £50,000 in start-up capitalThis is why I subscribe to this sub. I never knew I wanted to know the difference until right now.

How are those giant prize winning vegetables, like the 150lb zucchini, grown?
|
they are purpose bred to be that large because competitions for large veggies exist. Vegetables dont have a very long lifespan, so if you are mindful, you can breed specific traits in plants pretty quickly. Those zucchini and the popular giant pumpkins have been selectively bred together for a few decades to be just really big over every other trait And this is being done by more than one person, you can buy seeds from plants that are going to grow giant versions of the vegetable, and start breeding them yourself, but since its such a niche thing, just like niche dog breeds, its a small market. pumpkin and zucchini and other vine-type squash plants are actually really easy to control the breeding because of the way their flowers are shaped, They have these really deep trumpet flowers that only open in the morning, so you just wait for the flower, pollinate by hand the flowers of plants you want to cross breed, snip off the flowers of ones you don't want, and then carefully tape up the flower you want to create your new vegetable with your crossbred seeds, so that bugs don't bring other pollen and pollinate with a plant you didn't intend.

Other than making room for other patients, why don't dentists fix everything in one appointment?
|
You may try to find a different dentist. Mine, for example, will try to only schedule an appointment if she can preform two procedures during one appointment. Like cleaning and an exam, or a filling and x-rays, or some such like thatNot sure in your case, probably for insurance money. I have done multiple cavities at once. And also had all 4 wisdom teeth out at once, used local not general anesthesia. You can numb the whole mouth.

Why do the fastest runners tend to be black?
|
A couple of speculative answers, in addition to /u/MrAloha808's point. "Black" and "White" aren't really groups, as there's as much variation between as there is within. Nonetheless people with black skin outnumber people with white skin, so their best runners are recruited from a larger population. Also, if you're using international athletics as a measure of running prowess, it's worth mentioning that many black athletes are from countries with higher extremes of poverty, meaning less access to other sports, such as sailing, polo and counter strikeSomething that is scientifically backed is the fact that black people tend to have more muscle mass. Medically we use this information everyday. When looking at kidney function one of the major markers is something called creatinine. It comes from muscles. Creatinine levels are substantially higher in black people and this is usually accounted for in equations calculating creatinine levels in black people. Aka: black people have more muscle mass. I believe the current generalized value is 20% greater muscle mass than white peopleResearchers out of Howard and Duke Universities [theorize] that because black people tend to have longer legs and shorter torsos than whites. It lends to a higher center of gravity and leads not only longer strides but faster foot speed.

Hostels. How they work and how they differ from hotels. Also why they are so popular in Europe?
|
They are very cheap hotels, usually with multiple beds in the same room. The are popular in Europe, because combined with Europe's well developed mass transit system, it makes for a cheap and flexible way to travel. Hostels typically exist in city centers where regular rooms are very expensive. In the US, without the same sort of mass transit, this sort of travel requires a car. With a car, you can sleep in it, stay at a campground, or simply drive to a cheaper hotel outside of the city, making hostels less useful.

why do snakes slither instead of inching like a worm?
|
Because their physiology is completely different. Worms are invertebrates, meaning they don't possess a single bone in their body. Snakes are reptiles . That means there are numerous evolutionary steps between them. IIRC, snakes do stretch their bodies a little but because of their spine, they have limitations on how much they can expand or shrink.

Why do male testicles sometimes retract up into the abdomen?
|
Testicles need to be kept at *exactly* the right temperature to make healthy sperm. Unfortunately, that temperature is colder than your body's natural temperature and is too specific to regulate normally. Thus, the balls moved out of your body to keep away from your heat, but they can be moved closer or further away depending on their needs. As for the "Men were once women" thing, in the womb, boys develop ovaries first before they are converted into testacles and moved down. There's actually a genetic mutation which delays that transformation until *puberty,* meaning for about the first 12 years of your life, you look like a prepubescent girl in every wayAdrenalin will do it. I once almost died and my balls were gone. Nutsack was normal but empty. Had to wait for breathing to return to normal before I could find them again.

I see flies and moths in my house all the time. Why don't I see a whole lot of dead insect bodies everywhere?

Spiders. The house spiders that you share your space with are eating them, and the left over bits are broken down reasonably quickly by bacteria or chemical reactions and they turn to dust.

How do the authorities have dental records to identify people?

Why intervention is Libya considered a failure despite successfully saving human lives and toppling a brutal dictatorship?

What is the difference between cabbage and lettuce?
|
The main difference between the two is that they are from different plant families. Cabbage is a leafy vegetable, from the 'Brassicacea' family, whereas Lettuce is from the 'Asteraceae' family. The difference can also be seen in nutritional values within each of them. Most lettuce types have less calories and more vitamin A and potassium than cabbage. Alternately, Cabbage has a lot more vitamin C and fibre than that of lettuce. The differences are minute, but they are there.

I'm having a lot of trouble wrapping my mind around the concept of 'Cinematic Excess'
|
My understanding from listening to friends is basically as follows: When you go to the movies, you *need* a certain level of detail to understand it . But there are other details that you *don't* need to see . Now, while you don't *need* to see the trees or the rest of the garden, it *does* provide a richer, more engaging experience. Another method might be to have an image/sound that gets repeated over and over again throughout the movie. You don't *need* to see it more than once, but the repetition can be a clever technique. Or perhaps the scene switches from colour to black-and-white. Again, the colour palette makes no difference to the actual story, but it helps weave a compelling narrative. Even the music soundtrack can be 'excess'. Often it has nothing to do with the story, but it still builds an emotional atmosphere that sucks you in.

Being sued for money when you have none
|
First step is the court awards a judgment against you that says you owe the money. It's good for 20 years and will show up on your credit report. What happens next is up to the creditor. If you have a bank account they can file a garnishment and take it. If you have a job they can garnish your wages provides its own rules for "exemptions". Certain types and amounts of property are "exempt" from collection, meaning that another party cannot take it from you, even if they have a judgment against you. Everything else would be subject to the collection process, which includes garnishment of bank accounts and wages and/or seizure of property to be sold at auction. For example, Florida provides an unlimited "homestead" exemption to debtors for the home they live in. If I own a mansion worth $5 million, and I live there, my creditors almost certainly cannot put a lien or collect from my house If you don't have anything for the other party to collect, that is their problem. You cannot get blood from a stone, as they say. It is not a crime to not pay a judgment, but it is a crime to lie about what you have or don't have in order to avoid execution of a judgment. Bankruptcy can often provide protection/benefits beyond those available through state law, such as a possible discharge of the debt I hope this helps your understandingAs an aside, lawyers who have any semblance of ethics will tell their clients if they think somebody isn't collectable .as in you'll never get money even if you're in the right and get a judgment. Sometimes clients will pursue anyway just on "principle".

how can small cellphone carriers (metropcs, criket, etc...) charge less for the "same" service?
|
It's because they rent the towers they use from the majors and do not have contractual subsidies for phone contracts that drive up costs. They also are not accountable for maintenance of the hardware and towers which keeps the costs lower.Because the real costs to cellphone providers is much smaller than what they charge the big guys have a HUGE profit margin. The smaller guys compete by not marking things up as much.MPCS is a good example - Metro LTE for the most part uses T-Mobile's network, and we share the same billing systems. Coming back to your question, the major difference would be your quality of service - where the most important part is how we prioritize your data speeds. For example, even with the Metro unlimited plan, a T-Mobile customer will be ahead of you in the line in regards to speeds that they receive. But you should understand that this is the case only in cases of network congestion. So if you are in the middle of LA during busy hour, you will likely notice a degradation in your speeds before a Tmo customer would. There are also other service differentiators, like the fact that the Tmo unlimited plan offers limited tethering, while for Metro tethering is blocked for the unlimited plan. Let me know if you have any other questions. :)

How is the VR experience of a phone with an attachment like Galaxy S7 different from that of Occulus Rift?
|
There are several different aspects to this as of right now which may change in the future. The first is that phones don't have nearly as much processing power or storage space as a gaming PC, this means games are often short or re-use the same content throughout the game. Graphics are often simple and use low resolution textures, they also have poor batteries and can get hot quickly. Secondly you then also have the screens used in these phones, the Oculus Rift can update the screen 90 times a second vs a phones 60. This many not sound like much but it makes a huge difference. Specifically the GearVR only displays an image for a fraction of a frame to avoid blur, so the higher the screens refresh rate = less noticeable flicker Lastly is cost, the target market for GearVR is more of a casual audience so the headset of often of lower quality in design and will have less features so that the manufacturers can sell it at a specific price point, the biggest drawback right now with the current generation of GearVR headsets is that there is no positional tracking. With an Oculus Rift or Vive the displays inside the headsets have been specifically made for VR, the optics have been paired perfectly to the displays and the whole unit is of much higher quality. Please note that this answer is only applicable to current generation devices , VR is probably the fastest introduction of a completely brand new technology I've ever seen so the landscape and direction VR takes will change very quickly and without warning, for all we know in a year things could be vastly different. A new generation of virtual reality headsets may very well be totally self contained and wireless, meaning you do not need a PC or a phone and that the 'computer' for the device is in the headset itself. This is, at present the most likely way vr will advance and become it's own medium and this would offer a middle-ground between 'GearVR' mobile Vr and PC vr.

How does a U.S. Destroyer, a vessel equiped with advanced technological systems, that is supposed to engage in tactical naval warfare, collide with a cargo ship?
|
Massive and systemic watch-keeping failure on the part of the Naval Vessel's crew. Heads are going to roll here. Court-martials, possibly criminal-negligence charges. There is no excuse for this. None. Navy Ships have multiple people in the pilot house, lookouts all over the ship, people in CIC monitoring surface contacts. State of the art computer processors crunching enough data to take down 10's of targets at mach speeds. Able to scan the environment with different radar systems. The Cargo ship had the right of way : > *Collision Regulations Rule 15: When two power-driven vessels are crossing, the vessel which has the other on the starboard side must give way and avoid crossing ahead of her.* Navy ships also are required to have other vessels standoff outside their respective exclusion zones, to avoid [shit like this] happening. It's a complete breakdown of every single navigational procedure.I don't know if it's relevant this time, but a little over 16 years ago, the US Navy proved that distractions can cause disasters. In early 2001, a Los Angeles-class submarine conducted an emergency surfacing maneuver directly underneath a Japanese fishing boat. The ship sank, and 9 people onboard died, including 4 high school students. Courtesy the US Navy's "Distinguished Visitor Embarkation" program, [the $2.1 billion fast attack submarine was under the control of an oil company CEO and a freelance sports writer for the maneuver, as directed by the ship's captain.] EDIT: If you don't have a picture in your head of a sub surfacing in an emergency, [it looks like this]. Imagine that submarine coming up directly underneath a boat and you have the right idea. Anyway, if something crazy like that can happen once, perhaps it can happen again

Why sometimes when I sleep, in my dreams I try to get out of bed but my body refuse move, and gets harder to breathe but felt so real?
|
When you sleep your body turns off its motors so you don't act out your dreams. But sometimes your eyes wake up before the rest of your body has restarted its motors, so you cannot move, all you can do is stare ahead. Your dreams may continue at this point, though they will warp to adhere to the environment your eyes are looking at. It is normal to experience hallucinations at this point. It can be terrifying, particularly because you can't move, can't speak, and are stuck watching what might be horrifying hallucinations. If you fall back asleep after this you may have another, and another. In my experience, the terror grows with each episode; and with each episode, you may be left feeling more drained, making you terrified to go back to sleep, but so tired that you cannot help it. Some people feel tightness in their chest like a great weight is resting upon them. You may hear what is going on around you, but those sounds may be warped in terrible ways . The upside to these episodes is that they can lead to lucid dreaming, where you'll be entirely conscious of your dreams and be able to control each aspect. I had these episodes every day for a long time and during that time it taught me how to lucid dream, to where now it is just a normal part of my dreaming. If you want to escape an episode try wiggling your toes and fingers. It can provide rapid relief. To prevent them, try sleeping on your back or covering your eyes when you sleep. You may still experience them when you eyes are covered, but they are forgettable with no visually distressing aspect. You may find that these occur with much greater frequency during turbulent times in your life, times of great stress or trauma.

Why do we clap our hands as an act of cheering?
|
There's no real reason really. We could have chosen any gesture to represent cheering such as snapping fingers or stomping feet. However, clapping makes a lot of noise, doesn't require another surface nearby, and takes barely any technique to be effective. Some people just started doing it, and it caught on because there wasn't a need for something different.Humans are apes. When apes get excited they go apeshit. Clapping is a homo way to go apeshit without going totally bananas. Although in less "cultured" or "hoitytoity" gatherings humans will still whoop, holler and bang fists.Clapping is not just because you're cheering. It's because you want another person to know that you're cheering. It's something you have available to you at all times. It's not necessarily just hands, it's just you making sound of approval using whatever method is appropriate to your culture.This video explains the phenomenon well I think. _URL_0_', "Vsauce did a segment on this one once. Basically it's a simple way for a crowd to simply give applause as a unit. Imagine being a performer and having to give a hand shake to 300 or more people after a show. It's way more effort and gives the same amount of respect as clapping your hands.Because you are so happy you start to give yourself high-fives. but actually it has something to do with the primal reflex of making sounds with your body. Look at she chimpanzees. They also bang their hand on everything when they're _URL_1_'s also the best way to "make some noise" without shouting, which might be inappropriate in some situationsI found this really interesting: etymology for the word [explode] . ex- "out" plaudere "to clap the hands, applaud." Signifying a climax, a final coming together of audience and artist. Echoic noise, percussive flesh, coming together in crescendo.

why does the human body need O2 in oder to get rid of Carbon? Why cant it just release the carbon as a gas or something?

The body doesn't just take an O2 and stick a carbon onto it. The body has a very complicated set of chemical reactions, called the [Krebs cycle], that it uses for energy. The Krebs cycle is how your cells turn your food into usable energy to do stuff and stay alive. It takes your food nutrients, like carbs and protein, and breaks them down to recharge a chemical called adenosine triphosphate . ATP is a little messenger molecule that carries energy from place to place inside your cells. When it runs out of energy it has to be recharged by another run through the Krebs cycle. One of the steps in the Krebs cycle requires oxygen. This is why you need to breathe in oxygen to live. And in addition to ATP, there are two byproducts of the cycle: carbon dioxide, and water. You get rid of the CO2 by exhaling it.

Why do different foods of the same mass have different amounts of calories?
|
Your body isn't converting all the mass of a burger into energy lol. Only some of the energy bound up in food is utilized by your body, and **none** of it comes from converting mass into energy. Your body takes chemical potential energy from bonds between atoms in your food and utilizes it to drive all the processes that keep you alive. Much of the actual mass of the food is used as raw material to make structures your body needs like new cells etc. Some of that material is used wholesale because your body can't produce it on its own . Any mass your body can't use generally leaves the body with other waste. Some food has more, and more energetic, bonds that your body is capable of converting into energy than others.

Why is your throat so much more sore in the morning than any other time when you have a cold?
|
Because you've been lying down and not swallowing, the extra thick mucus your nose is producing during your cold has been dripping down your throat all night and irritating the crap out of it. During the day you swallow, drink, and eat which helps clear the mucus out. You're probably also blowing your nose instead of just letting it drip down your throat.

How does alcohol by volume work?
|
Depends on the volume. Two 5.2% abv beers at 12 fl oz a piece. Would equal one 10.4% ABV 12 fl oz beer. The volume is very important.It's complicated, but yes. If you weigh the same and one of you consume double the volume but half the percentage over the same time, you both end up with the same alcohol content in your blood more or less. That is until a point. The body transports and recycles alcohol, much like the garbage disposal. Your body transport the ingested alcohol to your liver and the liver is like a recycling factory, where the alcohol is used in other products and the rest products and the leftover alcohol is made into stuff that is easier to dispose of. The parts that can be used as fuel are used, but this usage leads to global warming in your head, since the byproducts are bad. You might have other fuel ressources, like glucose, but Saudi Arabia tells you not to use them, so you keep fueling your head with alcohol. At first it seems like a good idea, later it seems great. But then you realise you fucked up: a massive flood is coming and you can't stop it! Everything is wept from your mind as the mass flood is the only thing engulfing your weeping face. You lost all your friends, your family. Welcome to the future!

How do companies discover that they've been hacked?
|
If a good hacker didn't leave a footprint then the company wouldn't know about the leak, and you would never hear about the company having a leak. The Sony hack wasn't noticed by Sony. It was the hacker group that publicly exposed the hack.

How come not everybody sees the same colours when looking at Benhams Disk? [Repost]
|
You can't look at Benham's disk on a monitor and know what color you "would" see on the real thing, ironically enough for almost the exact same reason we see color there in the first place. With a real-world disk, we see colors because some of our eye's receptors fire faster or linger longer than others - So a rapid white/black transition favors whatever receptors send the strongest signal back to the brain. Think of it like a poll - "Hey red, what do you see?" "Umm, something, I guess " "Blue? What about you?" "Yeah, something bluish" "Green?" "YES, oh wow, yes, dude, you have to see this, so greenly awesome, hey can we stop at Taco Bell later?". Going back to monitors, you can't see the right color because it will depend less on your eye and more on which color of subpixels in your monitor has the longest retain time - Frequently red, for LCDsI see it as kind of a lime green. What do other people see? EDIT: this is interesting, I used a different computer, and now I see it as a desaturated navy blue

why does my body decide that post shower, after I'm all nice and clean, is an excellent time to take a shit?
|
I know what you're talking about, but I think its a false equivalency. We don't really give much thought or complain during the day when we need to take a shit. But after showers, we put more significance into our shit urges, because we just showered, and remember them. There really isn't a correlation I don't think.

What exactly does the UK mean by "killing encryption"?
|
All information transmitted over the Internet could be decrypted at government request. Things like private Facebook groups, stored email, online transactions, that C4 you bought from a Tor store, you know, stuff terrorists might do. It's government trying to harm everyone, not just the very unfortunate very few that happen to be injured in terrorist attacks.

how does quartz work in watches/clocks?
|
The quartz itself is sliced into a very thin tuning fork shape, and is then connected to an oscillator circuit, which takes power from the battery, and starts the quartz vibrating. The miniature quartz tuning fork vibrates at exactly 32,768 times per second . Because of the nature of quartz, these vibration emit their own weak, but just as exact, electric pulses. These electric pulses are then used as the basis of the timing of the watch. 32,768 may seem like a strange number to work with. However, computers work more easily with powers of 2, and [2^ is 32,768]!

Why do most porn sites not use HTTPS?
|
If you were to submit your credit card information on the internet, the information needs to go from your computer to the server. What hackers can do is to "sniff" the traffic, and decode the information that is sent, consequently getting your credit card information. What HTTPS does is encrypt the information on the computer, send it, and then decrypt it on the server. So even if hackers get a hold of the traffic, they have no way of decrypting it. This is awesome, but requires a little bit of extra cost . Note that this does nothing in protecting your identity. Your IP address is still sent as is. Most porn sites are simply view-only, so users are not actually submitting any private information, therefore, no need to implement HTTPS . However, most paid sites where you have to pay for membership, I would imagine do have HTTPS protocol installed.I think it's because the affiliate and ad-networks don't work with https enabled. Most porn sites make their money in advertisement. If it is a porn site with some kind of payment, you will usually be redirected to a site using https.

If various species naturally went extinct even without human influence in the past, why is it still important that species are going extinct? Is it not just nature taking its course?
|
Regions in which humans have developed habitats saw a massive increase in the rate at which megafauna started going extinct. This is WAY higher than what ecologists refer to as the background rate of extinction . Mass extinctions that don't open up very many new niches , such as the ones that we are causing, only hurt biodiversity, and imbalance ecosystems. And whether you realize it or not, we rely very heavily on the things mother nature does for us in order to get byIf people naturally die without human influence, why is it still important that people get killed in war? Isnt just nature taking his course?', "Mass extinctions have only occurred 5 times in the history of organic life. It's important to not go down the road of setting off a chain reaction of food chain disruption. If this ends up being the early beginnings of the 6th mass extinction, earthly life is in trouble.The biosphere is, to us, like a giant laboratory that tells us much about ourselves and the Universe. Each species is an experimental result. But when they disappear, unstudied, we loose the results and are poorer for that.Because like climate change, it's our fault that it's happening hundreds of times faster than it would naturally.

Why are valve amps so much more powerful and louder than solid state amps with the same wattage?
|
Valve amps produce a subjectively pleasing sound when they are driven past their "clean" limits. Among other reasons, they tend to distort in a more gradual way than solid state amps. So first off, you're intentionally exceeding the limits whereas you're staying within the limits of a solid state amp and using some separate function to create the "overdrive" or "distortion" you're looking for . A 50 watt tube amp is pushed to, or beyond, 50 watts just to get a pleasing overdrive sound. A 50 watt solid state amp is always kept below, say, 45 watts to avoid its less-desirable overdrive sound. Secondly, the tube amp creates distortion sooner due to its "less perfect" operation, for a number of reasons. This results in a "clean" power rating that occurs earlier and below the absolute limits of the amplifier. With a solid state amp capable of outputting 8 volts into an 8 ohm speaker, that creates 1 amp of current and 8 watts of power. But the "clean" sine wave contains less energy, in the 6ish volt average range, because a natural "clean" sine wave sound is not maximum power all the time, it's a smooth shape. Distorting the hell out of the signal, outputting a square wave, and therefore driving max power all the time time, can push output to that 8 watt physical limit. But a tube amp which can output 8 watts without distortion could perhaps keep pushing to 10 volts and 11ish watts just not cleanly. The limit of its undistorted operation came way before the absolute physical limits of its operation. So when you do overdrive it and push the maximum physical limits, the power is higher than you might expect from its rated output. Again, this is because its rated "clean" output is created by a number of limitations other than absolute power supply/peak output limitations.

Why is there a little wall in the gas container of a lighter?
|
A longer, thinner cylinder is stronger than a shorter, fatter one. Alas, the short, fat shape is more desirable in a lighter. The result is that a long, thin cylinder is folded in half to get the desired strength in the desired shape.It helps keep fuel in reach of the dip tube and keep any air inside away from the exit so you're trying to ignite pure butane, not a weak mixture in air.

How does the nonprofit tobacco control organization known as Truth Initiative have a revenue of more then $957 million?
|
Oh, the tobacco industry pays for them to advertise against tobacco. Ironic In the 1950s, there were the first studies coming out that stated tobacco is quite bad for your health. Over the next half century, this fact became more widely known and the first lawsuits against tobacco companies came up. In the 1990s, this climaxed, the vast majority of states sued the tobacco industry, claiming their suppression of the health risks of tobacco if they knew about it or negligence to research a product if they didn't costed the states lots of money in public medical care bills. This resulted in a little something called the Master Settlement Agreement, which resulted in many things, including that the states medical bills being paid by the tobacco companies and the tobacco industry would fund a non-profit to combat smoking, particularly youth smoking. This organization is known as the Truth Initiative. All in all, the tobacco companies were forced to pay 200 billion for 25 years after the lawsuit, and more for longer. 900 million is their assets, not revenue. They still make a good amount off this lawsuit though.

Why do guitars have 6 strings? Wouldn't it be better if they had 5 because we have 5 fingers?
|
It has nothing to do with number of Fingers, you can use different methods of strumming and picking that are way more efficient than assigning one string to each finger. Its more a matter of Sound, the more strings you have, the higher the amount of notes when you play a chord. Or since you thought about picking it seemed: the more strings on a Guitar the broader the range of notes you can use in a Melody', "They don't always. Six strings sort of evolved because it covers the most common chords in European music and still be comfortable for a human hand. But it is not hard to find two, four and twelve string instruments that act & play similarly to a guitar.The reason is more related to history. The 6-string guitar we know and love nowadays is a close-cousin to the lute and the loud, which have 4 or 5 strings, and were used as a lead instrument, since the strings were using high pitched, which are prefered for soloing . The 6-string guitar appeared as a way to have a plucked string-like portable instrument with a broader range, thus, two lower strings were added, adjusting the pitch to let guitar players play chords with lowish bass notes. [More can be read here] .You don't pick strings based on the number of fingers you have, you base it on the range of notes you want to be able to play. 6 strings because that's the range was sufficient for composers at the time of creation. These days you can even have 12 string guitars.

why we can't see the streak of the Milky Way the way in cameras capture it?
|
Light pollution. If there's too much ambient light in the atmosphere, the stars aren't as easily seen. When people take those awesome shots of the milky way, they're either in *very* isolated places, the picture was edited to make the stars more visible, or both. I live in a very rural area, and on a clear night I can still only *just barely* make out the milky way.

how is the common cold still a thing?
|
For one, the cold virus mutates constantly. To come up with any sort of cure/vaccine would require a lot more work than it would for other diseases. Considering that the cold is rarely a deadly or debilitating disease, the amount of research that would be needed to eradicate it would be a huge waste of money.

How do collision prevention systems on cars work?
|
Usually, there is an IR range finder, which attempts to find how far from the nearest forward object you are. The car takes this distance, runs a calculation based on the current velocity to determine the minimum stopping distance. The system will do this kind of math quite frequently , in order to determine if the object in front of you is actually getting closer . Should it be determined that the distance between you and the object is falling fast enough , if the minimum stopping distance at your current conditions is within X% of the distance of the object, then your car will attempt to stop automatically.

Why is American Express widely not accepted at many retail stores?
|
Merchants have to pay more to accept American Express. While they may only pay 2%-3% for that Visa purchase you made, it would be closer to 5% for AmexCredit card companies make money in one of three main ways: * By charging interest on unpaid balances* By charging merchants a percentage of sales as a transaction fee* By charging cardholders an annual membership or other fees Most credit card companies make money primarily as lenders. Most of their customers carry unpaid balances and the interest rates on these cards is generally much higher than people would pay for other kinds of debt . American Express works on a somewhat different model. They offer cards primarily to businesses and require that the full balance be paid off in full every month . Since Amex is not making money from interest, they increase the amount they charge in the other two areas. Cardholders typically pay an annual fee . Amex also charges merchants a higher percentage of the transaction in fees. This arrangement is very convenient for businesses that use the Amex card and avoid interest charges, but it is far less convenient for merchants. They may pay something like double the fee they would pay on a Visa purchase, with no perceived benefit. In some cases, merchants report that they get *worse* support from American Express than from other card companies. If merchants are unhappy with the terms, they have few options other than lumping it or refusing to accept American Express cards for purchases.

Why is breathing in faster than breathing out?
|
This might be a better fit for /r/answers but there is some physiology involved in your answer that might be good for eli5. Imagine you had a straw that you could suck water out of a glass with but you can only suck, you can't blow into the straw. You can very quickly pull water through the straw by sucking harder. But the only way to get water to back into the glass is to take your mouth off the straw and let gravity pull it back down the straw. So no matter how quickly you can get the water up the straw, you can't make it go back down any quicker. It's kind of like being able to pull something, but not being able to push it. You can always pull faster, but if you can't push it, you have less control over how fast it's pushed. That's the simple explanation. The basic answer is that when we breath in we are using a muscle to pull the diaphragm down. When we breath out we aren't using a muscle to move the diaphragm; it's the tension of the diaphragm that pulls it back to it's starting position. This is the way we naturally breath when we aren't thinking about it. You can take direct control of your diaphragm though and breath however you want both pushing and pulling, but that takes concentration and uses more energy than the natural unconscious breathing. So breathing in, you tense a muscle, it pulls down on the diaphragm which reduces pressure in the lungs causing air to be drawn in. And breathing out you relax that muscle, and the natural tension of the diaphragm pulls it back up, increasing pressure in the lungs and forcing the air back out. Also you can try to consciously breath in slow and exhale fast, and you will start to feel the muscles becoming a little uncomfortable because it requires much more work doing it like that than the natural way.

What's up with sloths?
|
They just chill up in trees away from most predators that would otherwise be able to hunt them. By being super lazy, they don't use as much energy, so they don't have to process as much food. They only need to leave their tree every week or so to poop. As long as they have a readily available food source that they don't have to chase after, being lazily slow isn't really a disadvantage given their mode of avoiding predators.

Why are there always sales just before the financial year ends?
|
In ye olden days of business, stores would keep a ledger of their sales. Until they turned a profit, all sales were written down in red ink. Around the fourth quarter of the year when the Holidays were fast approaching, they 'd start to turn a profit and write their numbers down in black ink. Hence the terms "have red in my ledger" and "Black Friday". Many stores around this time are trying to do three things: 1) Get as far into the black as possible to cover bonuses, sales targets, surplus capital etc. 2) Get rid of excess and/or outdated stock quickly and cheaply, to make way for new products. 3) Land new customers who otherwise haven't or wouldn't typically shop at said retailer.Because many people in the company have performance targets or even bonuses tied to revenue in the fiscal year. So if the big day is approaching and they need a little bump to earn a bonus, then it's sale time. Of course there is also the situation where its just being used as a marketing ploy. Their announced sale may have zero connection to their internal reporting or bonus structure.

Why are batteries (Such as AA, AAA, D, ect.) so expensive?
|
Because people need them and will pay the prices charged. The price has stabilized at the highest point people will accept.They aren't that expensive [if you buy them from the right place] in decent quantities. If you buy brand names, however, you're paying massive markups for convenience & the massive advertising campaigns they have.

How come people are not experiencing discomfort during highspeed train rides?
|
These high speed trains accelerate quickly, but not that quickly. I don't know about the Japanese Maglev but the German one named 'Transrapid' had a maximum acceleration of 1.3 m/s² which is faster than normal trains but not really much different from acceleration experienced in cars. The German ICE highspeed train has a maximum acceleration of 0.71 m/s². By comparison 9.8 m/s² is 1G and humans can survive up to 3G for durations over 25 seconds just fine without special equipment. You would hard poressed to find any vehicle that actually accelerates so much for so long because after accelerating for 25 seconds at 3G you have already broken the soundbarrier. The important thing for the comfort of human passenger is not really acceleration but the rate of change of acceleration itself. As long as that is kept low enough you will not even stumble. The direction of down may seemingly change for you a bit as the floor seems to tilt and you may feel slightly heavier as if going up in a fast elevator but that is it. Once the vehicle you are in travels at a constant speed you won't be able to tell any difference to standing still as long as you don't look outside.

Why does my head hurt when I get a headache?
|
It depends on what is causing your headache. Stress headaches, for example, can be caused by excessive tension in the muscles around the head. Many headaches are generally thought to be the result of the blood vessels surrounding your brain either opening up or clamping down . These actions can cause pain receptors above your brain to be triggered. Newer theories suggest that chemicals in your brain are a more significant part of the pain of a headache. Basically, there is no real "pain" being caused in your brain, it's just the result of areas in your brain being triggered that normally acknowledge pain occurring -- kinda like a sensor that is malfunctioning. In reality, it's probably some combination of the two.

Why does the US have so many mattress stores?
|
That's like asking why there are so many brands of toilet paper. Given the sheer number of people who use them, multiplied by how often you replace them, there is definitely room for profit. Also mattresses have a very high profit margin. They are essentially cloth, padding, and a small amount of metal and wood, sold for hundreds if not thousands of dollars.

Why do I feel like I haven't really slept if I have vivid dreams during the night?
|
It's not that the vivid dreams make you tired, it's the fact that you are waking up during a dream - waking out of REM sleep tends to leave you a bit groggy. Most of the dreams during the night you don't remember, which explains why this happens only when you remember the dream.

Explain the argument that the color pink doesn't really exist.
|
A color is a certain wavelength of electromagnetic radiation. The "color" pink does not appear on the electromagnetic spectrum. Instead, it is how we perceive a certain combination of wavelengths, and therefore itself not a cookie. Of course, this is all just arguing semantics. As far as anyone in the real world is concerned, pink is a color', "The color pink exists. Maybe what you're referring to is its impure nature. A color like red or green can correspond to a specific wavelength of light but pink is a combination of multiple wavelengths. Think of it like [something near red]+[white] .

The right to abolish government
|
You're right, it isn't. The Declaration holds no rights for Americans; those are found in the Constitution.
|
Why is it that when people in very prestigious positions lose their jobs, they have to tender a resignation, but in everyday jobs, you just get fired?
|
Most jobs in the USA are at-will; this means that either side can terminate the relationship at any time. You can quit whenever, and you can be fired whenever, for nearly any reason or no reason. Most upper management positions, however, are on contract. This means that the employee and the company sign an agreement that the person can only be fired for certain reasons. If there's disagreement over those reasons, a firing might lead to a lawsuit. So instead, the organization and the employee negotiate an end to the contract. If they agree, the employee resigns and agrees not to sue for termination of the contract.I think they don't get fired because the board, or whoever is in charge, is worried about lawsuits. So they are "asked" to resign. Then they can include language in the resignation as to why they are resigning. They can also avoid mentioning the sensitive aspects of why they were REALLY asked to leave. Like if a SO wanted to dump you because they thought you were flirting with someone on FB and thought you kissed horribly. Rather than accuse you of these things, they "ask" you to resign, and then you can state in your letter that you were incompatible and want to pursue other interests.I'll give an example, just to provide context. Your football coach has signed a 5-year contract, paying him $5 million each year. But year #3 just ended, the team stinks, and the team is still under contract to pay him $10M over the next two years. They make the decision to fire the coach. As part of that decision, the coach will accept a few million instead of the full contract, but he will be allowed to seek employment somewhere else.Also if people resign they are not entitled to unemployment insurance in the USMy employer will allow most office employees the chance to resign over being fired. The only exception is for gross misconduct.

Why is it in companies like Twitter's interests to allow other people to produce clients like Tweebot? Wouldn't it be better for them to allow only their own app?

People like choice. If Tweetbot can provide a better Twitter client, then Twitter is able to get more users. More users means more money, and more money is the meaning of life.

Why can't you put a cast on a horse's leg instead of killing it if it breaks it's leg?
|
Horse limbs are quite complicated anatomically. They also do not tolerate casts in the manner a person can. Broken legs in horses would also require a body sling to reduce the weight on the injured limb. This requires very intense care as well as costTwo reasons really. 1. The cost. Most animals are less valuable than the cost of treatment2. The problem is, because their bones have become lighter," Hall told me. "They're very strong, to carry their weight, yet they're light, for them to be able to go fast. So, unfortunately, sometimes, when they break, they just shatter." When that happens, it is not possible to repair the bone, and not just because it is now in lots of little pieces that won't heal together. Another issue is what Hall called "plastic deformation", meaning that the bone bends before it breaks and it is the bent shape that is preserved in the pieces. Even if it were possible to put the pieces back together, you would end up with a madly bent bone.One of the reasons is that horses will often thrash around when they come out of anesthesia after they're broken bone has been fixed, often re-injuring it beyond repair. Another reason is that their hoof laminae usually can't take the added burden of weight that standing on 3 legs causes. The hoof will peel away from the bony structure, making the horse lame on its other feet. That kind of injury is not fixable. The race horse Barbaro eventually had to be put down when his hoof capsule detached from his foot, after many months of attempting to heal his broken leg.

why is alcohol accepted in many places where Cannabis is not?
|
Man I want to know this one too! As far as I understand, it’s all about marketing. There’s a great episode of Stuff You Should Know that touches on this topic I think it’s called ‘How marijuana works’The man responsible for this is Harry Anslinger. He was an official at the Department of Prohibition. In the 30s when the prohibition on alcohol ended he was affraid of losing his job, so he convinced people that cannabis made people dangerous . He got enough support that the drug was made illegal even if for a long time it was not.It's all politics. Marijuana was made illegal out of fear of Mexicans who smoked it being rapists , and so Nixon could arrest hippies and black people Alcohol is big money, and can pay off politicians to keep weed illegal, they know it would cut into their profits big time.

How to people string up these super long zip lines?
|
One method is to have the high point tied off and then you toss it down and drag it out to the low point. The other would be to tie off the low point and then have a free climber carry the high point up to the higher tie point. Shooting them with some kind of grappling hook gun is common in movies, but not in real life.

How does having sickle cell protect against malaria?
|
We don't know exactly, but it has something do do with the fact that the Malaria parasite lives in the red blood cells for part of their development. There are different theories, but they basically come down to one of two things: * Either the red blood cells of people with sickle-cell disease are just more difficult for the parasites to live in.* Or the red blood cells are more sensitive so that the parasites damage them and the body recognizes them as defective and recycles them before the parasites can complete their development.

Whats happening in the brain that allows me to instantly recognize that song i hate on the radio and scramble to change the station? why can't shazam or sound hound work that fast?
|
The difference between something like Shazam and you is that Shazam is browsing through a library of songs that is over 11 million deep. assuming each song is 3 minutes on average, that's over 64 years of continuous music. Quite literally, you would die before you could listen to every song Shazam has to browse through. You, on the other hand, are listening to a radio station that maybe has a few hundred songs going at the same time. When you hear a song come on, you don't have to wonder if it's a gospel hymn from the 30's, you know that it's the same song they've been playing over and over for weeks. As for a device to block songs you hate, most internet radio services like Pandora or Spotify allow you to flag songs you don't like and they won't pop up again.

How is Morgan Freeman's voice so 'compelling' and 'powerful'? And what can one do to learn to have an authoritative voice?
|
He has a deep voice, which is relatively difficult to develop. Far easier to develop is his manner of speaking, which is slow and distinct. He pronounces each word in sequence rather than slurring them together and pauses for emphasis where needed. The impression such speech gives is that your words are considered - that your thoughts are complete before the sentence begins rather than running along apace with it. In a sense, it's *silence* that gives the sense of authority. The boss isn't the one who does the talking - they're the one who talks *last*. Once they've talked, there's nothing left to say.Morgan Freeman, James Earl Jones, Don LaFontaine, etc. all have voices with substantial low frequency content, in addition to a timbre or modulation which presents high contrast to underlying noise or music program material, making them stand out well. You can simulate this somewhat by inhaling sulfur hexafluoride and then talking - it has the opposite effect on your voice that helium has.

How does UV light cause colors to fade like flags outdoors. Also why does it happen with colors like red?

The dyes in the flags are made of chemicals, and UV light causes these chemicals to degrade into colorless ones. Each dye has a different chemical makeup, so some dyes, like red, degrade quickly into white, while others, like blue, just turn yellow

Why does the House "always win" in gambling?
|
The odds of winning any gambling are set out so the house always has an advantage. This is usually just a few points of a percentage but over tens of millions of dollars pouring through a casino, this leads to millions in profit. You basically have like a 49% chance of winning, so over thousands of plays, the casino ALWAYS ends up ahead. Even professional gamblers, who earn their living my playing poker or blackjack, games they can manipulate, only manage to get to 51% or 52% win rate, however they make their money by betting high when they know they a higher than average chance of winning', "It doesn't always win but the odds are in their favour so in the long run given no adverse reactions they win. Draws always favour the house so if the result of a game is a draw house wins or on roulette 0 house wins etc.

Why is glass so inert to acids?
|
Dat silicon dioxide. Acids react by having a weakly held hydrogen that the other part of the molecule doesn't care for much, and would really rather have a metal in its place, as metals are much more likely to give off outer electrons to a non-metal than hydrogen is. Silicon dioxide, however, is already in a really good place with its electrons, so the acid doesn't have the necessary pull to substitute either the Silicon or oxygen for its hydrogen.It depends on the type of glass that you are using but typically glass is an inert for most chemicals. It is mainly the properties of the silicon which causes it to keep its structure and not release oxides to react with the acids. If you used metals it would corrode easily more likely because of the composition and free oxidation that will happen by removing free electrons from the column. Throughout your classwork you will see that although this glass is useful here it may not be best for some other applications. Similar to how certain polymers will react differently with certain acids.

Why do you get veinier when you work out?
|
When ya run around or workout, your cells need more energy to keep going at the heightened rate. That means your heart has to start pumping faster, and \'cos your body's doing more work, you get hot. When you get hot, your body has a few ways of cooling you down, like sweating, or hairs standing up. One of these ways is to raise the veins slightly in your skin so they're closer to the air, and can get rid of the heat easier. As the nice man below said, "vasodilation" or widening of the veins, also occurs, to help let the blood flow faster and easier, which helps add to the illusion of them being about to burst out. Correct any mistakes, I'm basing this on GCSE biology, and it's not recent eitherVascularity is caused by dilation of your veins to allow more oxygenated blood to be sent to the working muscle.

If I open a can of Coke while skydiving, does the liquid stay in the can?
|
The ISS, along with everything and everyone in it, is falling freely towards earth at all times. Thus, the situation on the ISS is analogous to your question, without all the side effects of atmospheric drag. There are a few really cool videos made by the crew of the ISS that show how things behave in free fall. [This] is one of the videos I am talking aboutNo the bubbles in the can and the random movements of your hand holding the can will cause the liquid to come out. However it will not come out as a direct result of your falling since the can, the liquid and your body will all be falling towards the earth at the same speed.

What are the benefits of having private internet access (for personal use) and why are people obsessed over it?
|
Specifically, PrivateInternetAccess, if you are referring to that brand/company, is a provider of an anonymous VPN. Their VPN allows one to mask where their traffic is originating from by sending it through a third party. In addition, they accept forms of payment which reduce the paper trail behind their identity. In addition, VPNs may be useful for avoiding blocked/censored websites/services, and they encrypt all traffic between the computer and VPN.

Can someone please explain to me what is so bad about Tesla's intended direct-to-customer sales models and not going through dealers?
|
"Eliminating the middle-man? Never as easy as it sounds. About 50% of the human race is middle-men, and they don't take kindly to being eliminated." --Malcolm Reynolds, *Firefly*It's because they are cutting out the major car dealers. There is nothing wrong with them selling like that. The states that have banned them just have politicians that are "friends" with one or more major car manufacturer that is loosing out by Tesla not being part of their brandThe [official rationale] from the The New Jersey Coalition of Automotive Retailer association is: "Jim Appleton, president of NJ CAR, says Tesla never should have been granted the right to sell cars in New Jersey in the first place because the state believes there’s a public benefit to promoting a separation between automakers and auto sellers. If there’s a warranty issue or recall notice, said Appleton, dealers see a chance to help customers; the manufacturer sees an expense." . The real answer is that NJ CAR's role is to protect the car dealers it represents from losing business as they would through direct sales from Tesla, and [700 grand in political donations] bought enough influence to do so. Ain't democracy grand?', "because the car dealer business owners don't get a cut of the sales. and tesla sales are competing against their existing dealership business. and local business owners have more lobbyiests than Tesla, a corporation from california that only has a store prescence in-state.

The economics of a chinese buffet. (how do they make enough money?)
|
I could think of some reasons why but they may not be the whole truth: * You don't need as much staff because you aren't serving people at their tables * You have a set menu so you can make things in bulk and have less chefs required for cooking * You can order food in bulk since you will have a pretty good idea of your most popular items * Because the cost to eat is less expensive, you can get a lot of people to come in. The $ add up", 'i owned a Chinese buffet place in california, so here is the break down vs regular resturant food cost: about 40-60% labor : about 15% but we have a lot higher income, i mean gross sales. so that would make up. it is the same idea of wholesale business which is you have more sales volume.1. Reduced wait staff2. Food can be prepared in bulk instead of cooked to order3. Food does not have to portioned or plated4. Typically less expensive items are on the buffet5. Some people will gorge themselves, but many will eat the same as if they ordered off the menu Remember, food costs are small portion of what it costs to run a restaurant. You don't pay for food, you pay to sit in a nice build while people cook the food and bring it to you.

Once a President is in office and installs his government, how does the federal government (continue to)investigate him?
|
The Congress does the investigations, just like they did with Bill Clinton for over six years. This is the check on Executive powerCongressional oversight can investigate through subpoena power to produce testimony, documents, other evidence. It is limited in prosecutorial power and dependent on the DoJ to issue legal charges. They do have the power of the purse and contempt citation to force complianceEssentially because the President is NOT above the law! There are in many areas DIFFERENT laws that apply to the President but that does not make him ABOVE the law. The FBI is independent as are some other federal agencies

Why do we say "I'm getting on the bus/train/plane?" Yet say "I'm getting in the car?"
|
Why do you park in the driveway and drive on the parkway?if i had to take a guess id say that a bus/train/airplane are all public transportation whereas a car is private in most cases. But I have no ideaI think it mostly has to do with method of ingress and egress. You walk onto a bus, plane, train. You do not walk into a car.

How do all of these companies that claim to "consolidate your debt" work?
|
It's a loan. They make interest. Since pretty much every debt has interest, they can charge a little more interest , and sometimes even cut the amount owed. Even with a high but not completely unreasonable interest rate, can still be lower than credit card interest rates, or old loans issued in times of historically higher rates. If most of the debt is high interest, you come out owing less. But, as you say, the selling point often isn't *lower* payments, rather *easier* payments. You owe one company a bunch of money, rather than many companies some money, and you pay for the privilege of having to buy less envelopes and checks .

how do the bacteria in probiotic yogurt survive stomach acid and populate the intestines?
|
Most of them don't but a few will get through and once they are within the gut they will start multiplying if they can find a niche there. The intestine already has a huge bacterial population and they have a habit of killing their neighbours which is why probiotic* yoghurt etc needs to be taken repeatedly to establish a viable population. * probiotic really refers to certain nutrients that specifically help bacterial growth rather than the bacteria themselves but the term has been co-opted to mean both.

Where the superstition of walking under a ladder being bad luck come from?
|
It's dangerous for both you and the person who may be at the top of the ladder. Something could be dropped on your head or you could possibly knock over the ladder. Don't walk under ladders.

UV light in public conveniences.

Your mum is correct. Under UV light you can't see your veins to inject. It also works with blue bulbs I think but is more effective with UV. EDIT: Missed a word

What is the subreddit "wheredidthesodago" about?
|
It's making fun of infomercials. In a certain kind of commercial, , a certain set of tropes are always present. Most universal among them is a video, often in black and white, of someone utterly failing at a simple task, intended to demonstrate to the viewer why the new product is necessary. It's funny, because the new product is almost never necessary, so you have examples of people [too incompetent to operate a blanket]. [Here's a textbook example].

The chemical reactions that go on in my cell phone battery and how to make it last longer
|
It's like a really big game of red rover. When the battery is brand new all the kids line up on one side of a football field. This is the + team . When you use the battery kids run across the field to the other side to join the - team . Some kids can't keep running from team to team so they stop in the middle, and play with the grass, or do whatever. Each time more kids can't run the whole way. Till eventually only the fast kids are left. Thus - team fills up faster, and so does your + team. Meaning the battery life is much shorter. Now heres some crayons. I don't like the phrase, "lost it's elements." More like the elements don't play the battery game anymore.

Why couldn't T-Rex have been both predatory AND scavenging?
|
Language like this is usually used for disambiguation. It *can* lead to confusion in the process, but mostly it's to try and *avoid* it. There's often some overlap between behaviour. In fact, *most* carnivores will scavenge when given the chance. There just wasn't much hard evidence of this specifically existing for T-Rex, and it's easier to classify animals in 'either / or' groups, than catering to blurry, movable lines. Bear in mind, this find **doesn't** constitute proof, either . There could be numerous explanations for it, not all of which imply active hunting.

If mushrooms are made of chitin, a protein, why is the amount of protein listed in the nutritional information so low?
|
Chitin is a form of sugar - not protein. Since your question is still valid if you switch those words though, it is a type of sugar that our bodies cannot use. It acts just like fiber and passes right through so to speakFun fact, chitin is found in insect shells, and other animal parts.
