- In the first Matrix, Neo asks for guns, how would he get to the other rows of guns?
> Are they just for show? It's a movie, it's all just for show. It looks cooler to have many rows, so that's what they did.This is probably better suited for /r/AskScienceFiction. If you are looking for an answer that fits in with the constraints and laws of a particular movie/game/work of fiction, that is the place to ask
I have heard that the Xbox One and PS4 are like high end gaming PCs. Why do they cost so much less?
* Bulk discounts: manufacturers specify one type of component and buy millions of them.* Consoles also have predictable ordering cycles: this means you can order parts many months in advance, parts manufacturers love this since they can order raw materials way ahead of time which makes them cheaper.* Consoles are designed as a complete system: this means you don't have to make nearly as many components user-serviceable, which adds to cost. Cooling systems are designed for the whole console, so you get better performance with fewer, lower quality parts.* Interface control: since they make the console, console manufacturers get to be gatekeepers as to what runs on the console, that means they don't have to test **every** combination of power supply, RAM, processor, graphics card, sound card, webcam, keyboard, and on and on that could potentially cause issues. Software only has to run at a couple display resolutions instead of every resolution known to man like PCs have to deal with.They are not like high end gaming PCs. They will likely be as powerful as a current mid range PCThey're not *high end* PCs. They're a decent mid-range by today's standards, but nothing more. That's not to say they're crap. They're not. But consoles are very rarely in-tune with the latest technology advances. They are always a few steps behind. There are a host of reasons for this, not least of which is Price. If they truly were using "high end PC" components, then they *would* be around the same price. Also, high-end PCs have much greater requirements. Where the PS4 has roughly 500GB HDD, a high-end PC would have at least *quadruple* that, and on SSD .
how come so many shows on Fox make fun of Fox so much? Why does Fox keep them on the channel? Shows like Simpsons and Family Guy.
Aside from the fact that the shows are very popular and make the company a lot of money, letting shows like The Simpsons and Family Guy make fun of Fox boosts the company's corporate image. By letting shows poke fun at the company, Fox seems like a "good sport" and like they don't take themselves to seriously . You'll notice that when these shows make fun of Fox, they often pick on easy targets. For example, there is that one Family Guy joke when Peter lists off all of the "successful" Fox shows These shows have been cancelled and there really isn't any chance of them coming back. Sure it makes fun of Fox\' decision making, but it isn't maliciously attacking the network. What you don't see is Family Guy or the Simpsons calling Glenn Beck out as a moron, stating that Bill O\'Reilly is an asshole, or claiming that Rupert Murdoch is a corrupt chauvinist. Fox shows poke fun at, but don't openly defame their parent company because without the company, they wouldn't be on TV. It is like making fun of your boss; posting a "Dilbert" comic with the Pointy-Haired Boss on his door is ok, but calling him a fascist is crossing the line.Because they're popular. If the Simpsons bring in a lot of viewers, it would be a really bad business decision to cut them because they make fun of Fox.Contract. > When The Simpsons was developed for the half-hour show, James L. Brooks negotiated an unusual contract, in which the producers prevented the Fox network from interfering with the show. This contract made it possible to write several jokes about both the Fox network and Fox News. The fact that most networks use network notes to tinker with television shows is often parodied on The Simpsons. Creator Matt Groening has commented that this contract puts The Simpsons in a unique position and commentators have commented that it defies industry practices.
How do PC games have "bad ports" when the games themselves were made on them?
Games made for consoles: * Are using different technologies, so a lot of code has to be rewritten for PC.* Have fixed hardware that developers can optimize for. On the other side, PCs have a variety of different hardware with different performance, and software can vary too * Have fixed screen resolution and FPS, computer games that have to support many different monitors usually do not.* Have different controls. For PC version, keyboard+mouse must be added and it often sucks, because developers focus on gamepad . In addition: * Many game studios do not care and they outsource ports to cheaper external companies, some of them really suck.* Ports often have to be done quick and have lower priority then console versions due to different revenues on platforms. But it is an infinite circle, revenues on PC are low because many ports suck.
with glasses, can e.g. watching tv worsen your eyes?
No. The reason your vision goes bad is because they grow into an incorrect shape. Looking at a television isn't going to cause that to happen, and incorrect glasses are just going to cause eye strain.
Why is it so easy to work yourself into an anxious tizzy, but it isn't as easy to calm down again.
My guess is that it's evolutionarily advantageous to be more scared and anxious than calm and happy. Fear can motivate you to do something now to save your life. Calming down quickly doesn't appear to benefit humans enough to have been favorably pressured by evolution.
What happens when you reinstall your Windows OS over your computer?
The only risks you're really running are in deleting files you don't want to delete; re-installing Windows works best when you erase your hard drive and start over from scratch. Think of it like this: you buy some tropical fish, and every few weeks you scrub the gunk off the inside of the fish tank with a brush. This helps, but once in a while you've got to take the fish out, drain the water, scrub the tank and refill it with clean water before you put the fish back in. Back to your computer, your best bet is to get a friend who knows this better than you to come spend an afternoon helping. Basically, you're going to move your personal files onto a USB drive, reformat your hard drive, reinstall Windows and all your software like Office and iTunes, and move your personal files from the USB drive back onto the computer. On Windows computers I do this at least once a year, and the performance increase is usually pretty dramatic.
Why are drinks like coffee and tea gross when they are between luke warm and cold, but delicious when they are hot or iced?
I actually like the flavor of both at any temperature. It's probably just because I need the caffeine. According to [this] we have certain "channels" in our taste buds that affect the way we perceive flavor at different temperatures. These channels are called TRPM5. There was a scientific study done on the topic. Look it up - "Influence of Stimulus Temperature on Orosensory Perception and Variation with Taste Phenotype"I can drink them at any temperature personally.
Why do many herbivore's horns point backwards instead of forwards?
Many herbivores with horns such as those use them to show who the better mate between the males is. Or would be better to lead the pack. It is a show of dominance, but the intent is usually not to kill. You are right, horns facing forward would be better for killing, but that isn't what they are intended for to begin with
Why did people lose their retirement funds during the recession? Wasn't it protected or guaranteed?
Sensible investors didn't lose anything. The proper way to save for retirement is to automatically rebalance your portfolio as you get closer to retirement age. Basically there are some investments that grow faster, but can also lose faster in a recession - like stocks. Then other investments grow more slowly, but they're much safer and don't go down in a recession - like bonds. Finally there are other investments that tend to have different cycles than the stock market - like real estate and commodities. A correctly-set-up retirement account will be mostly stocks when you're young and then converted to mostly bonds by the time you're close to retirement age. When you hit retirement age, your account should be 100% safe investments like bonds Unfortunately, millions of people didn't invest this way - so if they had their retirement in stocks they gained more as they approached retirement but then suddenly saw their portfolio lose half its value.No. Usually by "retirement funds" people refer to their 401k or IRA accounts. They can be made up any number of various assets such as stocks and bonds. They can lose value.401K's are not guaranteed. Your money is put into an investment fund. If the fund tanks you lose your money.
Do musicians get paid everytime one of their songs is played on any radio station at any given time?
They do get paid royalties, but it's not a one-to-one pay out . Basically radio stations report which songs they've played during what programs to performing rights organizations which then decide how to divide up the royalties appropriately and give each composer/publisher/author a fair share based on play-time of their music during a given period.
Why is the word ignorant used as an insult, when everyone is ignorant.
Ignorant is used as an insult regarding things you are supposed to knowWell to be ignorant isn't necessarily an insult. But if you are saying it to someone when discussing a topic you are essentially saying "you don't know what you are talking about". Which can be seen as insulting. But saying that you are ignorant about a given topic isn't an insult, it might just be the truth.
Why we dont forget how to talk when they erase our memories?
When who erases our memories? At the moment we don't really know enough about the brain to *intentionally* remove memories from one without also causing severe damage to other systems. But if we're talking in terms of accidental memory loss then it's very common for one to lose more than just memory -- challenges interpreting or experiencing emotions or the loss of linguistic abilities are also common in cases of severe head trauma. So I guess the answer to your question is "We do!". Generally speaking, retrograde amnesia is actually relatively rare, and sometimes it's even temporary. What's far more common is anterograde amnesia, which is when the mind loses the ability for form *new* long-term memories. But in either case, loss of language skills isn't at all rare, just less widely featured in media. Memory loss stories are common in a lot of fiction, especially science fiction . In such stories, it would usually be far too inconvenient for a character to lose their memories AND their ability to participate in dialogue.
Why don't people sense the pressure of the atmosphere?
It isn't our brain filtering out something constant. Everything on Earth, including inanimate objects, is being pushed on by that pressure, all the time. All that air above you weighs a lot. It's exerting a force on you, a huge one. So you, and everything else, need to push back. Your body is pushing out constantly with a huge force against the atmosphere, as is everything here on Earth. We don't feel it because the forces balance each other out.
How does the 3DS work?
I assume you mean the 3D aspect? when the 3d is activated, the screen disaplays two slightly different images visible at different angles. one image is seen by your left eye, the other by your right. the images are such that they create the illusion of depth.
how could the Romans build 220 ships in 45 days?
You really have to take into perspective of how massive the roman populations expanded to at that time. And it's not exactly to say they built cruise ships, but smaller more manageable ships and boats; *as well as* the high level of slave driving and forced prisoner labor that took place.slavery. it's the foundation of "great empire building" think about what you could do with a million people that you don't have to pay wages to, that u could feed with cheapest food you could buy. and if 1000 of those people got sick and died, you could buy another 1000 for $100During the 1st century of the Roman Empire 35 to 40 percent of the entire population were slaves. If the emperor needed man power all he had to do was ask. Everyone wanted to get in his good graces and since slaves were your property you could loan them as you pleased.
What exactly gets lost when mass gets converted into energy?
Nothing gets 'lost' per se, that mass represents the energy that was originally bound up in the Hydrogen atoms. Helium atoms use less energy to keep everything together than two Hydrogen atoms, so some of that energy gets ejected from the newly minted helium atom. And that's how our sun shines. That little bit of mass that gets transferred into energy, times a very large number, per second. Bonus: [Why does the Sun Shine]", 'Nothing gets lost; the law of conservation of energy tells us that. Mass and energy are really just two forms of the same thing. Nothing gets lost from the fusion of hydrogen into helium, the difference in mass is just converted to Energy. And yes you *can* fission helium back into hydrogen but it requires a large input of energy. Lighter elements from hydrogen up to iron create energy from fusion but need energy to fission. For elements after iron, this is reversedIn short: there is energy stored in the interaction between protons and neutrons. When you split them you are changing the state they are in through quantum processes, and the end product is usually the proton, neutron and some radiation. The energy comes from the force that keeps them together , which you can think of like a spring that stores more energy as you stretch it. Nothing is really lost, but it just changes into other thingsOthers have already very well answered where the energy comes from, but I see you also asked about splitting it. In theory, one could, but that reaction would require the same amount of energy that the fusion produced, so there would be no gain. In fact, as our energy efficiency is less than 100%, there would be a net loss.
Why is it a bad idea to put dental glue for braces all over your teeth to prevent damage or for less maintenance?
It's easier and less expensive to just brush and floss, but even if you could encase your teeth in a protective shell, you would still need to brush and floss to protect your gums from disease. People with crowns, which cover the exposed tooth and cannot get cavities, can still develop cavities around the edge of the crown near the gumline.
What should I go to school for if I want the knowledge to fix audio equipment and gear? ( like synths, receivers, etc.)
Engineering, specifically electrical or electronic engineering. Luckily, Electrical engineering is a very broad field, so you could get your degree there and then decide later that you aren't super interested in audio equipment, but you'll still have a really great degree to fall back on in order to further your career goals. This is a question for Google, not for ELI5.
Why does the human eye see more shades of green than any other colour?
this is due to the Spectral sensitivity of the eye it perceve a larger intencity of green and red light than it does for blue, the eye has 3 type of colour receptors called cones and rods that are associated to the 3 primary colours, the amount of cones and rods for the 3 colours are not equal so you might perceve more green than you would for blue.
How can a telescope detect oxygen?
Spectroscopy. Different atoms and molecules absorb/emit light at different wavelengths. Spectroscopy is basically an analysis of the light we see coming from an object . We can compare that light to the emission patterns of elements and tell what a planet or star is made ofSpectroscopy. Atoms and molecules absorbed and emits like and other kinds of electromagnetic radiation as fixed frequency. The pattern is unique with absorbed/emitted colors. You will se lines of light or missing colors if you split the light in a prism [example with incandescent and florescent lamp] You can see the [spectral line of element here] A Neon light glow red in a electrical because the spectral line of neon is primary led lines. If we observed the exact same lines from space we would know that is it neon. They also absorb light the same colors so in 1868 during a solar eclipse unknown yellow spectral lines was detected. It was a new element named after the sun Helium that was detect. It was not until 1895 we found helium on earth. So if you look at the color a exited gas emits or what frequency of star light is absorbed you can determine what elements and molecules are in that gasAs far as I understand it, Telescopes are used to analyze stars and the materials theyre made out of by analyzing the spectrum of light the star emits each element causes a change
What are the origins of the Baptist church?
The original baptist church was started by a minister who had split from the Anglican church . From there it grew and spread, came to the new world, and became very diverse. Today it is not a guarantee that two baptists from different congregations will believe the same thing. The most unifying theology of baptists, and what they get their name from, is their believe in "believer's baptism". In the Catholic church a person is baptized as a baby, here the belief is that the act of being baptized forgives the original sin that human beings are born with. The belief of many protestants, including baptists, is that one should be baptized after they are old enough to express personal belief in the church's teachings.
Why can I never remember falling asleep?
Here's the scary thing: This must be what it's like to die, except you never wake up and have the memory of attempting to go to sleep.
why we get goosebumps when we hear a particularly beautiful voice or a certain scene in a movie?
The human brain is pretty amazing; it doesn't have to actually experience something to respond to it. Some external stimuli can lead your brain to start acting like you are experiencing that scene in real life. This leads to the release of chemicals in the brain which cause the body to physically react. The reason you get goosebumps comes down to evolution. A common response to fear, surprise, danger, and other strong emotions in mammals is to "puff up" their fur. This makes the mammal appear larger, and therefore more intimidating to what ever is making it afraid, surprised, etc. Do you have a cat nearby? Go scare it and you can see this in action. Now, humans have lost most of our hair, but we still have the brain pathways that say "strong emotion = raise hair." So when we expose ourselves to something the evokes strong feelings, our body tries to puff us up like a terrified catFYI, it is sometimes referred to as [frisson].
How can radio waves go through walls, but visible light can't?
Depends what the wall is made of. Various chemicals are transparent to various frequencies of light. Typically we also prefer walls people can't see through so we avoid materials that are transparent but you could choose the opposite.
why do your pupils dilate when you take Psychedelic drugs?
depends on the drugs or your definition of psychedelic. if you mean sensory hallucinations then its because they generally act as stimulants and since your eyes are now processing more light back at the cerebral end and your heart rate is up to feed your brain , then you dilate this dilation is therefore twofold - your eyes are literally able to take more light on, and also the nerves that stimulate your heart are closely related to the nerves that dilate your eyes. i would go so far as to say that the phrase "you need to open up" has a very literal meaning here, because your emotional openness is almost a gradient of how much you can activate and control/digest the info from this cluster of nerves, called your sympathetic and parasymphatetic nerves
Why are some former presidents referred to as former President and some referred to as President?
"President" is an official title, but it is also a job. If you were ever the President of the United States, you are entitled to use the title President for the rest of your life. Thus, everyone who was ever President is titled "President", but every one except Barack Obama is also a "former President"Just discretion. But I must say I also seem to hear "President Clinton" much more often than "Former President "
Why do sounds become 'distant' when you hang upside down?
Probably because gravity lets blood pool in some of the areas of your inner ear that normally aren't so full of blood, which slightly dampens how effective your ear drums are. Guessing.
Why is that when someone sentenced to 20-30 year in court but sometime only need to serve a year or so?
Judges usually don't give a simple sentence, they usually give a fixed term over a variable term . The news reads "sentenced to 20 years", but really it is "sentenced to 20 years with parole eligibility after 8". There is a fucking colossal variation in the behavior patterns and temperaments of people sentenced for the same crime. Some people are psychopaths who society was lucky enough to catch on a relatively small charge, some people commit heinous crimes but are mostly normal people who had one bad day. The gap between minimum and maximum sentencing are a mechanism to let manageable people out earlier and keep dangerous people in longer, with the fixed sentence being a kind of observation period where therapists and C.O.'s can document behavior so parole-board can decide if they can be trusted for early release or need to be kept out of society for as long as possible.
How do divers that don't have an oxygen tank not get brain damage from lack of air?
Mammals have bodily reflexes to being underwater known as [mammalian diving reflex]. Heart rates are reduced and our bodies let the outer layers cool so that it can conserve oxygen. As babies fresh out of the womb this reflex is generally very strong but we lose it overtime, free divers train to build this back up. Having said that, there is still a lot of risk involved. People blackout before they start to suffer brain damage and blacking out underwater can very quickly be a death sentencePart of the reason is understanding respiratory drive. Generally speaking, we breathe as much as we do not because we need oxygen, but because we need to get rid of carbon dioxide. Free divers like you described typically are experts at reducing the build up of carbon dioxide during their dives, mostly through not moving much , along with proper breathing techniques to reduce carbon dioxide levels in their system prior to diving.
Why do some businesses say no photos?
There could be many reasons. 1) Taking photos is discrating to the people working. This is common for performance venues. 2) Taking photos may capture information that the business is keeping secret. 3) The business may make their money by having people come into it to see what they have. You get this a lot with art galleries and museums. 4) Flash photography can degrade the objects. This is also common with museums and art galleries. 5) The business owners simply do not like pictures.
Why must an FCC approved device accept interference that may cause "undesired operation"?
It means that the device has a low priority on the hierarchy of communications, so if something is interfering with it, tough titty. As an example posted on a thread I found about this, someone pointed out that amateur radio and wireless LANs share a frequency band. Because amateur radio is on a higher priority than your wireless LAN, if your LAN gets shut down by the radio transmitter, you have no recourse. If your LAN is malfunctioning and messes up the radio transmitter, however, they can petition the FCC to order your WLAN shut down, because a lower-priority system is interfering with a higher-priority one.
Why is bureaucracy in India so stifling, and why does it seem to be accepted by everyday people?
A lot of things in India are blamed on the British . When it can't be blamed on the British it's blamed on Pakistan. When it can't be blamed on Pakistan it's blamed on India's less developed/poor states. When not them then it's the next village over, or the other political party, or that guy eating a hamburger. While in mainland China a man will vigorously deny that his kitchen is on fire even as smoke pours out the windows, in India the man will easily admit it but also be very quick tell you who is to blame for it . After independence the new Indian government almost immediately chose to adopt a communist-lite system for its economy. The country would retain private ownership but the government would directly manage a centrally planned economy like the USSR. To accomplish this feat a system was setup to tightly control what businesses could do based on the licence they had. If the government decided the country should grow more suger and less beans then the number of licences for growing suger would be increased while bean growing licences would be cut. This created a vast, corrupt and ultimately self-sustaining bureaucracy to handle all those licences. Imagine the DMV applied to nearly everything. Even though the system was ended in the 90s its legacy remains as it is essentially the only form of goverment most in India have ever known.
what does it mean to wear your heart on your sleeve?
It is a metaphor. It means that you allow your emotions to show- people can tell easily if you are happy, sad, angry, etc- ether by what you say, or how you act/compose yourself.It means that you're very emotionally open and willing to share your deep feelings with other people.
If water makes up 70% of our earth and we have things such as water purifiers, why are we running out of drinking water on our planet?
We're *not* running out. The problem isn't the amount of drinking water, it's the *distribution* of the water. Most developed countries could probably hydrate their population 50 times over, if they wanted . Whereas, for example, in hot African countries where water is scarce, contains diseases and there is little technology available to purify the water, *then* you get dehydration problems..[Water does NOT make up to 70% of our earth!]', "Water makes up 70% of the earth's surface, but almost all of it is *salt* water, which is basically useless. We can't drink it, we can't use it for agriculture, and we can't use it for industry. We can desalinate water, but that's very, very expensive. Out of the fresh water that's left , most of it is frozen in glaciers and ice caps. Lakes, rivers, ground water, and rainfall make up all that we can practically use. Some places have a lot more of these than others. There are plenty of arid areas where people are using more water than the local environment can replenish . _URL_1_", 'Because large scale water purification and desalinization is expensive and inefficient.A slight caveat to the amount of water on earth, only 2.75% of water is **fresh** water. [Here's a nice visual representation of water on Earth] Edit: and like harrisonbeaker said, water desalinization takes **a lot** of energy.
why is it that we are able to subconsciously control our bladders when we sleep? How is it that we manage not to piss ourselves?
Your body releases a hormone while you sleep called vasopressin which inhibits the production of urine. You produce less urine while you sleep, and it's a thicker, more dense liquid . People who have lower naturally occurring levels of vasopressin have to take a synthetic form of it called desmopressin before they go to sleep. And that's why we don't piss ourselves!
Why are dinosaurs marketed so much toward kids instead of other animals?
Dinosaurs only exist in the toy aisle of the store. For contrast, ponies are a real thing. You can actually buy your kid a pony, and teach it all about how much a pony eats and the work involved in picking up after a pony. There is a mix of upside and downside with a pony. Where I grew up, many kids had a "pet" cow as part of a 4H project. They took wonderful care of their cow, and showed them off in competitions. Then their took their cow down to the slaughterhouse and saw it converted into sides of beef they could sell or bring home and eat. That last step is a bittersweet experience for most young ranch children. It's an essential aspect of why cows are so numerous in the area, but it's very different that their relationship with the family dog. With dinos you never have to risk breaking the fantasy.Other animals, still being alive, give off stronger smells than dinosaurs. At least, that's one of the reasons my dogs are more into rabbits than dinos. Marketers are just trying to capitalize on this.
How do basic circuits work, what is voltage, resistance and current?
I think of it in terms of water. Water flows from high ground to low ground. Electricity flows from negative to positive. A river is when you have a channel for the water to move through. A circuit is when you have a conductor for the electricity to move through. Damn the river, the flow stops. Break the continuity of the circuit, the flow stops. Voltage would be the pressure in a water line. Your amperage or current would be how much water is moving. Resistance would be like debri in the river. The more debri, the more the river has to push. In a circuit you’re going to have a place with a negative charge connected to a place with a positive charge by a conductor, like a copper wire. The negative and positive want to balance out, so electrons flow from the negative to the positive to make it happen. But flowing can be hard because of the resistance in the conductor. You need voltage to push against the resistance, and the higher the resistance the harder you have to push. Some things like gold have almost no resistance and you can push very easily. Other things like rubber you will need a metric fuckton of voltage to push through.
Rugby and how its played
As an American, I hope someone will answer this question seriously. I'd like to be able to comment on that ludicrous display last night.
why do oceans exist?
Oceans cannot be absorbed into the sea bed because below the sea bed there is bedrock and the water is already saturated within the sea bed. Open water sits on top of the water within the sea bed.
Why do Americas call "Back Bacon", "Canadian Bacon" and when did that start?
It is called both Canadian Bacon and to a far lesser degree Irish Bacon or Back Bacon in the US. This is because they are the cuts that the Canadians and Irish call bacon. They are from the pork loin which is the back muscles toward the rear of the pig. But what we Americans call bacon is from the belly of the pig. Canada, Ireland, and the UK call it "American Bacon
Why do we use the word "late" when talking about deceased people?
One lesser-known meaning of "late" is "recently, but not any more". If, for example, you say, "A man late of London," you mean he used to live in London until just a short time ago, but now he lives somewhere else. From that came the expression "The late Mrs Smith," which was used as a euphemism to avoid using the word "dead". It basically means: "Mrs Smith, who used to exist until just a short time ago, but now no longer does."
Why isn't a Bluetooth connection instant?
Whenever two electronic devices talk to each other they go through what's called a "handshake" - basically it's the two devices trying to negotiate a common ground and make sure they can continue speaking in a stable fashion. > Device A: "Hey! Hey is anyone there?" > Device B: "Yeah, I'm here. Hi, I'm B. Wanna talk?" > Device A: "Hey B. Yeah I want to talk I'm on Bluetooth v. 2 and can talk at 2.1Mbit/s, how about you?" > Device B: "oooh no I can't do that I'm on Bluetooth v. 1.2 and can only talk at .7Mbit/s, is that ok?" > Device A: "Yeah that's not a problem I can handle that. Ok so we'll use v1.2 and talk at .7Mbit/s, deal?" > Device B: "Deal." > Devices are now officially connectedWhat you are expecting: A slave signals into a frequency band "Please talk to me". Your master connects. This is not what happens in practice. Bluetooth uses one of 3 different bands. So the slave will pick one band at random and transmit in it. When the master looks for a client, it scans each of the bands for a period, and then goes on to the next. If you are lucky, you will connect straight away, if you are not, you will have to wait. I don't think there is anything mandatory in the standard about how long you should scan each band, but I believe most devices spend one second in each. Depending on your phone, perhaps this might be configurable?
Why is shampoo almost always colored but conditioner is almost always white?
Hm, I guess that hasn't been my experience. Besides white I've had pink, blue, and yellow conditioner. Maybe it's just the brand you're buying?
Who notifies Google about newly made roads for their maps?
There are companies specialized in this sort of thing. They monitor local government announcements, planning permissions, etc., and when they see a new road is being constructed, they will go and collect the data. Google's maps business is big enough for them to own some companies like that as a subsidiary, but sometimes they might just hire external companies to gather the data and provide it in a format that's easy to plug into the Maps database.I may or may not work for said company You can do it yourself! Some of this is crowdsourced as people who live near new developments or road modifications know about it early on. Use [_URL_1_] to add new roads!
What is the difference between being a line cook and a chef?
Cool, that makes sense. I recently became the kitchen manager of my restaurant six months ago, the only reason why is because everyone else who worked there quit. But I make new recipes constantly and everyone calls me chef, but it feels weirdA line cook follows a recipe to prepare a dish. A chef sees what foods are available, creates recipes to utilize those foods, assembles those recipes into a menu, instructs the cooks how to prepare them, delegates tasks during the dinner rush, prepares food as necessary, and spot checks food as it goes out.
What's the difference between the words 'Muslim' and 'Islamic'?
"Muslim" refers to people. "Islamic" refers to everything *but* people: "Islamic art" "Islamic architecture" "the Islamic world." Like thatA "Muslim" is a follower of Islam. "Islamic" is used to describe anything related to Islam.Islam is a religion and it's followers are called Muslims. Something that is called Islamic is something that pertains to that religion.
Why does the U.S. always side with Israel over Palestine?
There's no diplomatic way to say this — Israel is considered to be culturally similar to the US, it has a representative government with stable political institutions, and American Jews are an important domestic political constituency.This is slightly less to do with US policy and more with elections, but it is worth noting that Sheldon Adelson makes it a point to donate to only Israel-friendly candidates. This might explain why Republican candidates are so adamant about emphasizing their ties to Israel .
Why do those cheesy pictures that get shared on Facebook always looks so grainy and pixelated?
They tend to pick up artifacts because the original image has gone through a chain of hundreds of computing devices which used different file formats and resolutions and so on. People do stupid shit with their files like opening them in Paint to edit them and then saving them in a different format. A lot of image formats, like jpeg, are "lossy." To save file size, a jpeg will essentially smooth out some of the fine details of the image, which gives you [artifacting]. If you pass an image around from one lossy file format to the next, it will artifact more and more each time its format changes, so the quality gets worse and worse.
why progress bars always hang on 99/100%
Progress bar values are basically made up by the developer. For some things they work pretty good. If you are downloading a 100MB file and have finished downloading 70MB then saying you are 70% done is pretty easy. For things like installing a game, where you have a huge number of files of different sizes it gets a little trickier, and for some things you can't really know ahead of time how long individual parts of the process will take, so you are really just guessing. This is why you will get stuck on a random number like 37% for a while, the instantly jump to 52%. Now in all cases though, developers will often have some sort of main execution section and when they finish that they are "pretty much done". So they set the progress bar to 99% or 100% and then they "just do some cleanup". Where cleanup are some usually small tasks they need to complete to really be finished with everything. Sometimes the developer simply underestimates exactly how much stuff they need to get done with or he has to wait on the OS for something that takes some time he didn't account for. If they were expecting the main work to take a significant amount of time, then maybe this cleanup really is 1% of the total time, but if the main work gets done fast it appears to lag here. There is also a "watch pot doesn't boil" effect since you are just waiting for that final %. TL;DR Because the percents are made up by programmers, and programmers are bad at estimating how long things will take
How do spark plugs break car windows while rocks can't?
concentration of force. a nail can break a window. a palm doesn't, even if there's more force applied.
. Why is voltage proportional to resistance when voltage drops after going through a resistor
It's not perfect, but the water analogy is a reasonable one. You can think of resistance as the size of a pipe, with larger resistances meaning smaller pipes. Voltage is proportional to resistance as long as current is kept constant. Constant current is analogous to constant flow, so that means that if you take two pipes of different sizes and ensure the flow rate is the same through both of them, you'll have to have a higher pressure on the smaller pipe. In practice , you tend to have pressure/voltage as the variable you can control and then the other two are inversely proportional, and expressing it that way is more intuitive.
How come video compression is getting better all the time, but sound files are still the same size as ever?
Audio compression is already really good, and has been for ages. People tend to be a bit more picky about audio quality than they are about video quality, for some reason. The bottom line is we don't really need better compression for audio files.
Online Universities and their value over a traditional degree. Is a degree from one just as good from the other?
In the UK this depends entirely on the reputation of the University. We have the Open University, which was established in 1969 specifically for distance learning regardless of previous qualifications. In 2009/10 it enrolled 250,000 students and in 2011 was ranked in the top 40 UK Universities and top 500 globally - quite an achievement for such a junior establishment. As a result degrees from the OU are well thought of and, because they are often taken by students in full time work, are indicative of good self discipline, organisation, motivation and dedication.Degrees from online universities are not valued the same as traditional degrees. Traditional degrees are still considered better, or more valuable. Two possible explanations: Universities often have their particular programs accredited by third party sources. For example, the AACSB gives accreditation to universities' business schools. It shows that ,that the school has been vetted and is competent. Similarly, it can be taken that if a school's program is not accredited, it is not viewed to be as competent. Online universities are still catching up with accreditation. A corollary to this is if you attend a school not accredited, you may not be able to transfer credits for relevant coursework to an accredited university. The other reason why online colleges are not seen as valuable is because often times , online colleges are for-profit ventures. While I understand that 'seeking financial solvency' is a goal held by all institutions of higher learning, the fact that online colleges are explicit in their goals of turning a profit is seen as unseemly and the online schools are viewed with suspicion as being degree mills. There are for-profit brick and mortar schools, too. And they are met with the same suspicion compared to a traditional 4 yr university. In the next 20 years, I think the perception will change. Part of that will be traditional colleges will start to offer coursework online and part of it will be for-profit colleges will take the next step and instead of being degree mills, will start to align their programs against traditional colleges and attain accreditation standards.
What is the IMF and what does it do?
The International Monetary Fund deals with money problems on a world-wide scale. Think of them like a bank, but for countries not people. It started by a bunch of countries putting in money, and other countries could borrow this money if they promised to change their economies to be more 'effective'. I put this in quotes because lots of people criticize the IMF's required changes as being just in the interest of Western powers like the USA.
Why should we keep funding NASA?
> So, what makes these investments worth while? We don't know ahead of time, which is the biggest reason. Advances made in the space program are both obvious and subtle . It leads to detecting threats to our infrastructure and insight into our environment . The point of exploration is that we don't know what is out there. The USA was founded by explorers, everything we have is the result of someone forging into the unknown. If your friend cannot see the potential gain from exploration then they are simply shortsighted.
What makes PewDiePie so popular?
The reason you find him childish and pointless is because his videos aren't made for you. PewDiePie is actually something of a genius because he knows his audience inside and out and knows how to entertain them. His target? Teenagers. They eat his stuff up because they're still at the stage where randomness is the funniest thing around. Sure, they'll grow out of it when they get a bit older, but there will always be more teenagers to take their place. EDIT: Had to do a bit of cleanup, but I also want to add that teenagers can be some of the most loyal fans around. My younger cousin loves PewDiePie and talks about him to anyone who is willing to listen. That kind of rabid word of mouth isn't usually something you get from adults, and since PewDiePie is so good at making these kids laugh, they're singing his praises in schools all across the world. That's some seriously powerful marketing. EDIT #2: Guys, replying to me and saying "I'm a teenager and I don't like PewDiePie" means nothing. I'm in my mid twenties and I don't like nor do I use Twitter. Just as well, very few of my friends - who are in their mid-to-late twenties too - use it. However, the fact remains that millions upon millions of people in my age group use and enjoy Twitter. Your personal preference is not necessarily representative of your entire age group.> I find them incredibly childlish and pointless. That's his selling point. He is supposed to scream like young girl on a roller coaster. You simply don't expect wits and skills from PewDiePie, all you expect would be those exaggerated reactions. The following are also the factors. Bandwagon effect: He has the highest subscribers in youtube which makes more people to visit his channel simply due to the popularity. Attractiveness: Some may say PDP is hot and that would increase his number of subscribers.
Why are emulators so tricky to make?
Emulation does not improve as the technology gets older. Emulation's difficulty depends on how different the platform is that is being emulated from the platform you want to emulate on. In the end it all comes down to the fact that emulators are non-profit, unofficial projects. Creators don't have the necessary documentation and they also have to avoid using copyright methods. This is the reason why emulators usually don't come with a BIOS. That's why they never work perfectly and their development takes a lóng time. If Sony, for example, would make an official PS2/PS3 emulator for the PC, they could get it to work perfectly.
With an inherently limited number of sources from past centuries to examine, will there come a time that we "run out of history?"
It's doubtful. The more we find out about history the more wrong we tend to discover we were about things. Even very recent history is full of misconceptions, falsehoods, and propaganda to dig through.It's certainly possible that we will eventually uncover every single piece of historical evidence in existence, although that doesn't mean that we'll ever stop looking. But that doesn't mean we'll ever have "nothing left to explore". Don't forget that the discovery of a new text or artifact is only the first step - the interpretation of past events is every bit as vital to our understanding of the past. New interpretations of events are created regularly, because every artifact could have been interpreted incorrectly, and every author of a historical document has their own personal biases that we need to examine and correct for when trying to determine the truth about an event. Even then, there's another piece to this - more history is being created every day. There are 7.5 billion people each with their own perspective on local, regional, and global events, and each of their stories is part of history. We'll never "run out of history" because it's *always* growing largerHistory is written every day. In 20-50 years today will be history. Like the crisis in Syria and whatnot.
Why do kittens go into a state of paralysis when grabbed by the scruff?
you can also use scruff training for teaching discipline, but only for kittens not adult cats. I wish I'd known this when I adopted mine as kittens. My 3 cats are all rescues, grew up with no mum so they have a bad habit of biting, nipping & generally bratty behavior that kitty mom would discipline out of them. _URL_0_
Why are batteries charge measured in mAh instead of Coulombs?
No real reason. It's just because that if you know that your circuit draws 100mA and your battery has a 1000mAh capacity then you know that your battery is going to last 10 hours. Easier than using C and then diving by 3600 second to get the number of hours.\r\rSame reason we measure energy in kWh instead of J
How are phobias acquired?
It's kinda like a psychological allergy. With an allergy, your immune system is overdoing a normal healthy response. A phobia is when generally healthy fears are exaggerated. When you have a phobia of something you shouldn't be scared of, there's normally a situational association. Like if you got lost when you were young and when trying to find your mom you got really scared by a cat. Now your scared of cats. These phobias can often be treated with exposure therapy. Most interesting are non-associative phobias, which are thought to be genetic because they establish themselves the very first time you're exposed to something.
What is this bizarre intersection?
It's called a [diverging diamond interchange]. It's considered one of the best recent innovations in interchange design because of all the [benefits it provides]. > It seems to make interchanging with I-77 easier Yep. That's just one of the benefits. > I imagine that it's super confusing for those unfamiliar with the intersection The first few times, maybe. But once you see them once or twice they're really no more complicated or confusing than any other intersection.
In times of severe to hyperinflation, why can't the government mandate a price ceiling to counteract?
Hyperinflation comes almost always because of a specific supply-shock problem. Something has increased uncertainty of the economy so so much that goods do not have any sort of reliable delivery in adequate amounts. Severe uncertainty can come from people hoarding in fear of a war or in fear of supplies cut off. It can also come from government printers of paper cash "degrading" the value of the cash by giving it to their friends. Everyone starts to mistrust the value of cash in their pocket believes that things won't be the same price tomorrow and may change to bartering or the black market. If sellers must slow down sales until something is always available and they use high prices to get more goods imported or made. This means raising prices over and over to make sure you are getting the best profit and can survive another day as a useful place to buy. Running out is an absolute failure and changes the prices from "high" to infinite or basically a complete failure. Paying for empty shelves can ruin and disappoint everyone and hyperinflation is a time when many businesses simply fail and must close. If a government mandates prices be locked in place, then stores will simply run out because those with goods to sell upstream of the markets will set prices on their own and send them to the black markets instead or sell them in another country for other types of money.
using coffee grounds to filter out lead ions from water.
scientists tested whether or not coffee grounds could be used to filter lead out of water. they found some interesting things out, firstly if more coffee grounds are being used more lead is removed from the water. Secondly neither water temperature nor bean type have any effect on the amount of lead removed. If the coffee grounds were used first though they worked better than fresh grounds, and finally this method was made less effective if the beans were treated with perchloric acid and if the treatment solution contained 10% or more of the acid the grounds stopped absorbing lead at all. and while this study does suggest at some point that grounds can be used in home filtration systems at this point odds are it would be very risky as you don't know how much lead is in the water or how much is being absorbed.
How do we know life on other planets will be of the same type as life on Earth?
I took a class in college about this actually, it had nothing to do with my major, but you don't pass up the chance to take a college class on aliens. It's been a few years, but from what I can remember, you're right, we don't know that life would be exactly like ours, but based on what we know now, that seems the most likely. As we understand it, life needs to have a solvent fluid. On Earth, this means water. There's a few other options that would work in theory , but there's problems with each of these that seem to make water the best option. Because we have such limited resources dedicated to the search for ET intelligence, we pretty well limit our search to those places and conditions that seem the most likely.We look for planets similar to ours in order to narrow our search for life. We know that planets similar to ours could host life, so it makes sense to first search those billions of planets, before the other billions of types of planets. There could be life out there unlike anything we have. Even on Earth we have some crazy diversity. For example: Blood in humans is red because it is iron based; whereas blood in a Horseshoe crab is blue because its blood is copper based. Two different elements facilitating the same biological function of transporting oxygen.On Earth we have what are called extremophiles which is life in extreme conditions. We have found life in the coldest and hottest places on earth and places with high toxicity. Due to this we cannot say for certain that life requires oxygen, water, other materials necessary for life on Earth but since many species all need these to live, it's easier to assume that other planets must need similar conditions to sustain life. However there are some cases where we consider extreme conditions that could sustain life. For example some moons in our outer solar system have been considered as they have underground oceans which could be heated from a liquid iron core or from tidal effects from their planet.
Why do I always feel like I need to piss right after I cum?
Because its your body's natural reflex to return your urethra to the proper pH to avoid bacteria growth and also to clean out and residual semen. If you fap, don't pee and go to bed. When you wake up to pee you might notice it splits in two streams, that's cause your piss is being blocked by a little bit of jism
Why is when my body is freezing (like making snow balls without gloves) and I go and put them under a hot sink they ich like crazy?
When your hands get cold the blood vessels in them contract. When you run them under *hot* water they expand rapidly, stretching them and the area around them, causing discomfort.Don't have the answer to that question, but don't use hot water, use cold water first until your hands have warmed up from freezing to cold, then increase temperature.
Why is it worthwhile to separate colors from whites in laundry?
In the past, you would often add bleach to whites to help clean them. However, it would destroy colored dyes, so you would need to separate them first.i believe upon first wash , some of the dyes can run and influence the color of the whites. i don't fucking know. i've only ever seen it in the movies.
Why does the TSA require a max limit per bottle of liquid/gel but no limit on the number of bottles?
Because the TSA's rules are arbitrary and meaningless.Because one 300 ml cream bomb can take out an airliner, but three 100 ml cream bombs cannot.The reason the liquids rule was implemented in the first place was because they were worried about people bringing liquid explosives on board . Breaking it into smaller bottles makes it more difficult to bring it on board and still maintaining a destructive effect. If you brought a 1-liter bottle, you wouldn't be allowed on board. If you brought ten 100ml bottles, it'd look really suspicious and the substances would likely get checked.The rules are totally arbitrary, and are designed more to make it look like they are protecting you. Also, prescription medications are exempt from the rule, so as long as your 300ml bottle is prescribed by a doctor you are good to go.
Why is the bathroom light switch in hotels outside the door?
It is a precaution so that you don't electrocute yourself trying to turn off or on something with wet hands. In UK,only pull cords are allowed inside bathrooms. Having switches inside bathroom may land you to into legal trouble.
How do scientists determine the calorie content of a food item? And the nutrient content?
They literally burn it, as far as I can tell. We got to do this in Chemistry with Pringles and a can of water suspended above the burning Pringles. We used a butt load of foil to direct all the hear towards the can. _URL_0_ Edit* My guess is that they use lasers to burn a piece and then measure the heat given off. As far as nutrient content I am not sure of the methodology.The calorie content is determined in two steps. 1) Burn the food and measure the heat produced. If you did only this, the psysiological calorie content would be severely overestimated because the body cannot digest everything in the food. For example fiber has a high technical calorie content, but a low physiological calorie content because it is indigestible. Hence you have take a second step. 2) Have an organism digest the food and burn their poop and measure the heat produced. Any undigestible parts of the food will end up in the poop, so subtracting 2) from 1) will result in the physiological calorie content. For the mineral content you something similar. You burn the food. Organic parts will burn, and ash will be left over, which contains the minerals . You can dissolve the ash in acid and then do use some standard chemical separation and quantification techniques to determine the amount of each metal, such as sodium, iron, magnesium For vitamins I don't know exactly how to do it, but maybe someone else can answer.
How can people be convicted for offensive statements?
Are you American? I ask because this is really weird for many Americans. In the rest of the world, it's pretty much agreed that inflicting emotional distress through offensive comments should be illegal. There's room for debate about just *how* offensive the comments must be, but it's basically only the USA that doesn't accept the basic premise.
Why does exposing factual information about a company lead to a successful lawsuit against you?
It depends on how that information was obtained and what kind of information you're talking about. If it's not public information, , think of it like insider trading. This information is an asset of the company, and by making it public, you stole this asset of the company. If it's whistleblowing of illegal activities, that is different. There are laws to protect whistleblowers. If it's simply unethical, then it is like theft of company property to expose their business practices.This needs context. Did the person sign an agreement to keep this information secret? Was it a corporate secret that required law breaking to discover or divulge? It can still damage a company/person to reveal true things about them, but is generally allowed unless there is a contractual reason why the whistleblower is breaking the law to reveal it.
Why aren't germicidal ultraviolet lights used everywhere, to prevent the spread of disease?
They use a wavelength of light that is cancer causing. Do you want to sit under a cancer causing light? Plus, they aren't all that effective to stop, say a sneeze from transmitting to another person. It takes some time to kill the germs.
How is kilogram a unit or mass and not weight? (flair physics)
Mass is a unit of how much "stuff" is in something - if two objects have the same number of particles , then they'll have the same mass, anywhere in the universe. Weight is a little different, because it's actually a unit of force - in most cases, it's the force of gravity we're talking about. And that'll change anywhere - you weigh slightly less at the top of Mt. Everest than you do in Death Valley, CA, because of your distance from the Earth. On the Moon, you weigh even less. But since weight is a force, we can also use it to measure, say, the force of a punch. So in everyday use, "mass" and "weight" are mostly interchangeable, because we figure that gravity isn't changing much across the Earth. But they're not exactly the same thing, because weight is based on more than just the mass.Because humans have pretty much exclusively lived on earth their entire existance, mass and weight are colloquially synonyms, however for the few spending meaningful amounts of time not on earth, or for various non-weight related applications of mass the difference between mass and weight become more apparent. Mass measures how much matter something has, weight measures how much force gravity exerts on it. If you were in orbit, your weight would be zero, but you would still have inertia due to your mass, or you have the same mass on the Moon as you do on earth but you have much less weight because the moon has less gravitational pull than the earth. The kilogram is a measure of mass . You need a scale with precision in the millionths to notice the variation in Earth's gravity.
Why wouldn't game developers make exact copies of good old games but with better graphics?
Well thats actually something that has been happening a lot in the game industry recently. There have been quite a few remakes / remasters. This year alone we got a re-releases of the last of us, kingdom hearts 2 and 4 Halo games so it's a thing that is happening. I think though that you more asking why don't they just create whole new games that just play like the old ones right? Well because people would get mad and not buy them. Consumers want to see some sort of improvement or progression when the see a sequel or newer version of a game. If you're not going to change the game in some way why should they buy it? Many consumers would just stick to playing the older games.
Why are button batteries so expensive?
Very often, miniaturisation *does* make things more expensive. However, I think you might simply be shopping in the wrong place. You can get packs of 20 LR44 button cells for well under $10 - it's a matter of shopping around.Common button cells contain silver or mercury for the cathode reaction. As silver is an expensive metal, and mercury a fairly expensive one too, the cost of production rises, and so the cost to consumers is too
Why was America reluctant to join the allies in WWII before Pearl Harbour?
The US was a lot more isolationist back then. Not only that, but they weren't the military powerhouse that they are today. The military might of the US was mostly untested. WWII is really when the US came into the forefront in that arena. It also wasn't that long after WWI; the US wasn't keen on getting themselves into something like that again. The US was also recovering from the great depression -- there were bigger things to worry about. I'm sure they thought it was a terrible idea, but they weren't in the business of involving themselves into affairs that did not directly affect them. Obviously, that has changed. :)", 'Well USA started lend lease in 1940 or so, tons of material were already heading towards SU and GB. There was just a ton of isolationism going on and people were tired of war until pearl harbor shocked them into action
Why don't seizures cause the heart to spasm erratically like other muscles?
Seizures start in the brain and send electrical signals to the muscles. But the heart has its own separate electrical systemOther muscles are under voluntary control; heartbeat is controlled by a signal from the brain which comes down a special nerve, the [vagus nerve]You have a central nervous system and a peripheral nervous system . Siezures only route signals from the brain through the somatic system which includes only sensory and motor neurons. The autonomic system, which includes your heart muscles, operates independently of these rogue signals.
Coughed up a tiny tooth?
Try to break it open. If it's tooth or bone, it'll have a soft interior where the marrow or pulp was. More likely is that it's either a tonsil stone that somehow didn't get stinky, or it's a piece of gravel that got kicked up into her mouth. If you can't break it, it's probably gravel, as a bone or tooth of that size will fracture relatively easily.
why does the mentos and diet coke geyser have to be diet coke?
The process is called nucleation. See those bubbles that form on the sides of your glass when you fill it with soda? They're bubbles of carbon dioxide, formed when the tiny cracks and crevices in the glass give them a place to form. A typical mint Menthos candy is covered in millions of microscopic pits, which give the carbon dioxide an dramatically large number of places to form bubbles. The reason it works better with Diet Coke is because of the presence of aspartame, a very low-calorie sweetener, which lowers the surface tension of the soda that would otherwise inhibit the bubble-forming process. [This] video explains it pretty well. If not, you can search it in YouTube and find lots of explanations.
Masturbation, oral sex, and other non-intercourse from an evolutionary perspective
its a way to bond and resolve conflict within groups. like with the bonobos.They do it for the same reasons we do. It's fun. They discover it through experimentation and/or observation.
How is love any different to being overly-attached?
Love is about wanting what is best for *them.* Being overly attached is all about *you.*To kind of follow up on my other comment differentiating between infatuation and "overly attached", I think the root difference between love and being overly attached is that one is the emotion that one feels, and over attachment is the way that one attempts to bond. They're two parts of an interaction or relationship, but neither necessitates or requires the other to exist. Edit: Not that that would make sense to a five year old, but Um In short: love is the emotion, over attachment is a behavior pattern
Why do we always think that dreams are real life despite them usually being obscure and unrealistic?
While dreaming, the part of your brain that determines if things are obscure and unrealistic is operating at a diminished capacity. In a sense, you are just not smart enough to realize there is anything wrong with an illogical situation.Same reason why we believe that vivid hallucinations are real . Our brains believe whatever they tell themselves to believe, even if rationally it makes no goddamn sense. In this case our brains are telling us that we're flying over New Zealand on a magic bicycle. Even though it's irrational our brain believes it to be true so it justifies the absurd visions. It's a magnificent phenomenon really. For example, you can be totally blind but if your brain believes you can still see you will adamantly refuse to accept you are blind. It's just how the brain works.
Why is the Mona Lisa worth so much money?
Think of it this way, little 5-year-old Billy/Sally: you have a really cool toy. All your friends look at that toy and want it. But you hold on to it, because it's special to you. Over the years, far into the future when you grow old, people still look at your toy and wish it was theirs, and think it looks really cool. After you pass away, people write songs about the toy and movies are written and watched with your toy in it. Suddenly, more and more people like your toy and want it. Some people are willing to pay a lot of money for your toy, but it's in a museum instead where everybody can see it. They can't touch it or play with it, but they can look at it. So people keep trying to buy it for more and more money, and this makes it cost a lot. Now stop chewing on the couch cushions and go clean your room.
why is it that big dogs drool alot while small dogs tend not to drool at all?
Larger animals have to work harder to keep cool. Volume, which determines the amount of heat produced, goes up with the cube of the length of the animal but surface area, which determines the rate that heat is lost, goes up with the square. Dogs cool off by panting while producing drool instead of sweating. Large dogs have to drool more to maintain their body temperature in the same way that overweight humans sweat more to keep cool.Large breeds are older than small ones because they were bred in the age when dogs were still used primarily as tools. No one purpose-breeds drooling dogs, but it's an early sign of population inbreeding. Get a big mutt, and it will drool less, and pant to stay cool without making a mess. Otherwise, Doggy von Hapsburg's weak chin is going to spill drool everywhere.
Why are springy doorstops made with maximum compression? Wouldn't they be more effective if they could be compressed to cushion the door's impact?
The coil is just for flexibility . If the spring was not compressed though when the door was pushed into it the spring would compress, absorbing the impact , however it would the release this compression, flinging the door back towards the person opening it . The more force the door was opened with potentially the faster the door would be returned towards the opener. This would probably cause a lot of accidents. However you would get some great YouTube compilationsWell with them being coiled like allows them to be flexible so if you kick them they move. They werent designed to cushion anything, but to stop the door handle from hitting the wall and possibly putting a hole itThey're made springy so when you accidentally kick them walking by, you don't tear them from the wooden baseboard. They're a "stop"-designed top keep the doorknob from making a hole in the wallboard/plaster-lath. They're not intended to keep some idiot from rocketing a high speed door into themI would like to leave a short story here.When I was in the 8th grade we put on a little science fair. Just for the grade 8s. One of the girls decided this would be her project and went about building a new spring. Since her project was easy to build on hand she put it together in the "planning class" and set it up at the door. It worked when she lightly pushed thw door against it, then when she slammed the door to show its stopping power the doorknob ended up hitting the wall, punching a small hole in the wall. On top of that the door sprang back and hit her in the face. Don't ask me why she stepped into the door. Maybe to try and catch it? Either way it knocked her on her ass and sent her to the bathroom bleeding. I laughed out loud so hard. Sadly no one else did and I was That Guy.They are not compressed, they are bound. Picky I know but they weren't made like normal springs and then squeezed until the coils bind, they are wound that way.
Why do different people like different climates?
I live in the Las Vegas Valley and chances are if you lived here long enough you grew a tolerance to heat, went to Norwalk and I was FREEZING. After long periods of time we get used to the temperatures in our enviroment, the same way early humans adopted to breathing atmospheric oxygen.
How is fire able to be on the surface of water?
There's something else on top of the water that is burning, like oil or fuel or flotsam.
Why are taxes on gasoline a fixed dollar amount when nearly every other tax is a percent of the sale?
The price of oil fluctuates wildly in response to geopolitical events and supply factors that state governments have no control over. Rather than try to budget in advance for such an impossibly unpredictable revenue source many governing bodies opt to impose a tax on volume instead. It's not perfectly predictable either, but it's a lot easier to plan for. You'd hate to budget for a 10% tax on $5 a gallon gas and then have the price crash to $1.30 a gallon for nine months.
Why Do Most Games These Days Indicate Loading With An Icon Instead of a Bar?
One less feature to support. Loading bars are actually pretty hard to do correctly. How much work is left to be done? What percentage of it is done? Keeping track of that adds development overhead to some overworked teams, and usually isn't particularly accurate. Modern game UIs tend to be heavyweight, too. Many of them involve libraries such as Scaleform , or even full 3D rendering, and it can be easier to skip all that and just throw an image up -- both in terms of development and runtime performance. Also, many games try to have shorter loading times, now. In my experience, the main thing people need to know is that the application hasn't crashed. A "throbber" can usually accomplish thatA lot of talk about loading bars being hard to impliment, or inaccurate in their estimate of time remaining . But I think it comes down to the same reason you won't find a clock in a waiting room. If you don't see the loading bar, you might be thinking "any second now it will load ", and disregard the actual time. Even if the loading progress bar is only indicative of the volume of memory currently loaded, people will naturally see the progress and estimate the time to completion. It's better that you don't know probably.This way the developers don't have to keep track of progress. They can just say 'start loading', load whatever they need , and when complete say 'done!'. Otherwise they'd have to figure out how much they're loading in total and how much of that they've already loaded.
How does electroplating work?
You stick what you want to electroplate into a pool of metal ions. You then run a current through it . The metal ions will stick to the thing you are electroplating. There are tons of applications, from aesthetics , adding conductivity . You can even coat with anti rust substances, or harder materials to increase durability.
How come all those gift cards for Steam, iTunes, Google Play, etc. have the exact same proportions and layout?
It's probably the same size as most credit cards, drivers licenses and so on. That size is normed as "ID-1": _URL_0_ Valve, Apple and Google just decided to use that, because they fit well in wallets and it's a nice know sizeIf you actually look at all those gift cards, they are made by the same company, and not sold by Steam or Apple or google. They simply are a physical piece of plastic or cardboard to give you a code.
How did Kirby Dick's documentary "This Film Is Not Yet Rated" show him appealing and discussing the movie with the MPAA,in the movie?
The film the MPAA reviews often is not completely finished. MPAA rating can be time consuming, so they send the movie early and finish up special effects and such, or even added scenes.
How is a Gendarmerie different from a National Guard or Police Force?
The Gendarmerie is a police force, but part of the military. They are different from military police because their jurisdiction is among civilian citizen populations rather than military personnel. They are different from the National Guard because they are a law enforcement agency rather than reserve troops for the military. They are different from the city police because their jurisdiction is national.
why did some men have misstresses in the past but now the term isn't used much?
Women didn't like it back then either, but it wasn't easy for women to get jobs, or at least good paying jobs. A lot of social stigma for a divorced or separated woman. So they had to put up with a lot of men being jerks. Cheating, physical and metal abuse, etc. Today women are more educated and independent, treat a woman badly and it's much easier for her to leave. So now there's a greater penalty for cheating.
Why do we hear new songs on repeat and love them but after a while we hate them?
Your brain is full of synapses--connections that fire when activated by stimuli, in this case, a song. You can think of it as a movie. The first few times you watch it you notice things you didn't the previous time. Once you watch it enough, you know each line of the characters. The same goes for a song. When your brain remembers each note and line in a song, the synapses have been cemented into your brain and you know what happens in the song. And in this, it is just like a movie where there is no adventure or excitement in watching it because you already know what happens. *note: I don't know anything but this sounds right*
How does a roomba work without damaging itself, such as falling down stairs etc?
The roomba has proximity sensors and spends its time mapping the room. It knows where hazards are and can avoid them. Just don't pick them up, or they might accidentally fall down stairs if it's not where they expect itself to be. And yes, they do actually clean, although not as well as a traditional vacuum. It's good for a daily cleaning so that dirt doesn't accumulate, but it won't get rid of deeply embedded dirt.
why does a scissor not work for left handed people but does for right handed?
scissors are actually made for right handed people typically, it's the way the right hand applies pressure on the handle aligns the blades. When you try and use your left hand, the blades separate and nothing cuts.My question is: do lefties use their right hand for scissors or just learn to use it with the left? It requires a weird hand tension/flexI am a lefty and I find that the blades are on the wrong side and make it slightly harder to see where I'm cutting. Also non "ambidextrous" scissors have the handle shaped in a way that doesn't fit your left hand very well.
