When to use a Chi Square (Goodness of fit) test vs. Matched pair T-Test vs. normal T-test | A chi-square test is used to measure differences in frequencies. For example, if I ask 500 people whether they prefer Coke or Pepsi, and I want to see if the number of votes for Coke is reliably different than the number for Pepsi, a chi-square test would be appropriate. By a normal t-test, I presume you mean one from ... |
why is it that when you are sick with a high temperature do you feel cold? | The fever exists because your body has set the temperature it is trying to maintain as higher than normal.

What are the major roadblocks to 'industrializing' spider silk? | Have you not heard of Spider Goats? _URL_14_ Here's the Wikipedia entry for the sort of father's of this business: _URL_15_ So. It's on the way. Some secret DARPA-equipped soldiers are probably wearing it right now. The main roadblock was simply that spiders don't produce enough of it under natural circumstances,and re... |
If I bred a red-eyed hedgehog and a blue-eyed hedgehog, I assume there'd be no chance of a purple-eyed offspring. But why not? | It would depend on the exact mechanic of inheritance. Sometimes genes are a like a single lightbulb you can screw in a red one or a blue once, and that all the choice you get. Other times it is like *two* lightbulbs. You have two reds, two blues, or one of each and get purple. This is similar to how red/green colorblin... |
Say there's a bag containing 10 marbles... | Depend what probability you are looking for: If you want everyone to pull a marble and once everyone pulled one, you check who pulled what, then the order doesn't matter. The last guy has 10% chance to have the red marble, just like anyone else. If every time someone pull a marble, you look at what he pulled and adjust... |
Why have real wages and income for lower and middle classes stagnated since the late 1970's? | Pers sort of touched on it, but the rest of them have missed the majority of the real answer. The real answer is that wages have ceased to track worker productivity. The reason for that, specifically, is that wages have NEVER been pegged to productivity. Wages are pegged to how much it costs to live, with some modifier... |
Why do instructors scream so much in the army? | Essentially to break you down to build you back up. The slightly longer format. We're all people with different likes, schedules, personalities, behaviours, ways of thinking. When you're on your own doing your own thing that's fine, when you're a cog in a greater machine, not so good. Everyone gets yelled at in basic, ... |
The United States' relationship with Saudi Arabia | Saudi Arabia has long been the world's biggest oil exporter, and the US imports a lot of oil, so that is the main basis of the economic relationship. In terms of politics, the main concern of the US would be that whomever runs Saudi Arabia should continue to be friendly enough toward the US that they will continue to d... |
Why is go considered a more complex game than chess? | It may seem counter intuitive, but having more pieces with more rules makes it easier for a computer to calculate, since there are only a certain, small number cases to consider. Whereas with Go, you can place anywhere, really. So you'll have to calculate every single possible move. More rules means less complexity, fo... |
How do children have so much energy compared to teenagers and adults? | They don't have resource management skills yet. They blow through all their energy at once, then crash. Adults know that they should save their energy for doing things the rest of the day. Kids just don't think that far ahead. Kids=Sprinters Adults= Long distance", 'Because they are yet to be enveloped into the unrelen... |
If fevers are part of our body's natural process to fighting off infection / viruses, why do we often take medication to take away the fever? | The reason we have fevers is that most things that invade the body and make us sick can only survive in a narrow range of temperatures. When you have a fever, your body is cooking the invaders out. However, if the fever gets too high, you start to cook too, and that's not good for you. It's good to let a fever run its ... |
In the shower, why does the temperature just before pain cause tremendous pleasure? | Does it even? I mean 'tremendous pleasure'? Does any temperature of water caused 'tremendous pleasure'?", 'It feels so good because I have eczema. Really helps to take away the itch without scratching. |
Why don't people with insomnia just do things while they're sitting awake at night? | You don't want to be productive. When I suffer from insomnia i just toss and turn all night feeling completely exhausted and miserable. Your body hurts and your mind breaks down. Anything to distract you from that is nice. |
Why sports leagues in the USA (e.g. the MLS and NBA) do not have relegation | College sports in America, especially football and basketball, have a huge following. Therefore, they occupy the niche that is held by lower-tier leagues in other parts of the world. Lower-tier football/basketball teams wouldn't be able to compete for fans with the local college team. |
Why do we try to save species that are going extinct? | There is no way of knowing if anything that may be unique to an organism could be very useful. For example, a poison produced by the cone snail is now a powerful pain medicine and compounds produced by sea squirts look promising for cancer research. It's impossible to know if the species going extinct might hold the an... |
The ISS has taken billions of dollars to build and is STILL under construction. Why is it only planned to operate until 2024? | Like everything in the universe, the ISS has to withstand the elements , and a decade or two of continous use will lead to the usual wear and tear. We can keep stuff on earth running for far longer because maintenance is cheap and easy. Maintaining a space spacion is neither nor. Also you can't just detach modules from... |
Why do some people believe that Dungeons & Dragons is an evil game? And, for that matter, is it? | Do we have the same mom? A lot of Christians detest the sort of material that D & D dabbles in I know my family did. I think that D & D is particularly disliked because of the roleplaying aspect It's not evil unless you feel it is", 'Some religious people believe that Dungeons and Dragons encourages witchcraft. These p... |
- If camera lenses are circular, why are pictures rectangles? | They can be circular the shape of pictures has to do with the media receiving light from the lens Typically film is either on a strip or a plate, but you could expose a round negative, or with digital the I believe CMOS sensor is typically rectangular but there's probably no reason you couldn't make it round or any oth... |
What happens to embassy staff in the event of war? | This depends greatly on the two nations involved. In recent years wars have been fairly asymmetrical, a developed country conducting military operations in a nation where it has little or no diplomatic presence. In those cases the embassy was likely closed years before when relations initially deteriorated and there ar... |
Why do all curly fries have that similar seasoning? | Arbys' curly fries are soaked in wheat starch to add crispness. Unfortunately, wheat starch has a bitter aftertaste when fried so they seasoned the hell out of them to cover it up. The seasoning combination proved to be popular and was subsequently copied.I went to a Jack Astor's and their "curly fries" didn't have any... |
Why do some states hold primaries earlier than other states? Why do we let them have so much political sway? | Both parties see it as being in their interest to have a 'primary season' rather than just one big nationwide primary day, since spreading out the media attention over such a long period of time theoretically gives voters time to learn about the candidates and make a choice. By the time the general election comes aroun... |
marijuana is becoming legal in a lot of places. How have large companies who test for drugs kept up with these law changes/altered their hiring processes? | They don't have to alter their hiring places. There's no law that businesses cannot discriminate against/fire you for smoking pot. |
Pixar and Dreamworks copying each other. | Earlier, it was more of a technology thing. 'Ooh, they animated water in a better way - let's work on that'. 'OMIGOSH! A new light scattering engine better than ours , let's better ours' and so on Now, it is a bit of that too and a bit of jumping on the bandwagon. Toy Story worked - so the idea of children's playthings... |
When the banks were bailed out, why weren't loans from those banks forgiven? | Because taking away all of their income would make it kind of hard to save them. It would be like if one of the conditions of chapter 11 bankruptcy reorganization would be that the company had to give its products away for free. To a bank, a loan is an asset and a deposit account like a checking or savings account is a... |
Why do I feel most productive right before I go to bed? | [Some people are night owls, some people are morning birds.] I personally feel like crashing late at night, although this pattern kinda cycles with me every few months. My 9 to 5 kinda sucks the life out of me. When I'm on vacation or something, I'm usually way more productive and creative during the night. |
How do we know what we're seeing is in its natural form? | We, in fact, know that what we see is not reality in its natural form. All of our sense data is heavily processed. E.g., you have a blind spot in each of your eyes. But you do not see that because your brain fills it in with approximated data. Your brain takes input and structures it into patterns that are useful but d... |
Why does touching metal to a metal cavity filling hurt like crazy? | so what happens is the saliva, metal and tooth form an electrochemical cell i think. and electricity flows from the tooth to the metal and back using the saliva as a little bridge. i would explain a little more but i have class right now lol here's a link for more reading: [Electrochemical Cell] EDIT: i am a chem major... |
Why do we say "what?" while talking to someone and, immediately after, process what they say? | Sometimes I say 'what?' because I wasn't listening. I wasn't expecting the other person to say something so I was deep in thought about something else and I heard the voice but wasn't focusing on the words. After a pause, sometimes I can replay the voice in my head and figure out what they said, but other times I can't... |
If cats only meow to communicate with humans, how do they communicate with each other? | The categories on the wikipedia article on [cat communication] include purring, calling , growling, hissing and spitting. Kittens 'mew' to adult cats when they want attention, and the meow is considered to be an extension of this by adult cats, to communicate demands. Mother cats use a 'chirr' sound to call their kitte... |
What is the purpose, during a flight, behind the take off routine of having your bags under your chairs and your tables in the up right and locked position? | If something goes wrong they don't want all that stuff flying around and hurting people. A plane doesn't need to crash for that to happen, either. |
why is there always construction that never seems finished? It seems like in many modern countries, construction is just not executed well | /u/edman007 summed it up very well, but I'd take the time to ask: by what metrics? What are you expecting? How fast should something be built and how did you arrive at this conclusion? There's a historic bridge in my city that's being redone after years of neglect. Construction had to shut off one of the exits entirely... |
What makes a certain hashing algorithm deprecated? | SHA-1 is now possible to crack because computers have become so fast and powerful. While it was infeasible to crack with typical computers 20 years ago, that's no longer the case. |
How did the Native Americans deal with the insects? | When I worked up in Northern Ontario one trick I learned from the local First Nations guys was to sit in the smoke of the fire and get all smokey. Get it in your hair and your clothes and the mosquitos don't bother you as much. |
If S. Korea has twice as many people as N. Korea, and has vastly superior technology and economic power - why are they threatened to the point of needing US assistance? | North Korea has a huge standing army. I think the fourth largest in the world. And the real danger isn't from North Korea. Like Vietnam, the US involvement in Korea is a holdover from the Cold War, when the real enemy was Communism! And back to standing armies. Guess who has the largest in the world? Don't kid yourself... |
Is it possible to tell the difference between a diamond found in a conflict mine and a diamond found in a legal manor? | I don't know of any legal manors in which one could find diamonds, but if you're looking for diamonds mined in a legal manner, the most reliable way to tell is by asking the jeweler from whom you're buying the diamonds, or search the retailer for information about where they get their diamonds from.You can ask for a ce... |
Why is there such a huge disparity in airline prices (example in text)? | The thing to understand here is that a lot of these airlines aren't really going after *you*. Airlines like United are courting business fliers. These are individuals who don't have to pay for their own tickets but *do* get the frequent flier miles! So an airline will go for offering them more services and more frequen... |
Why can't we store/use electrical energy from lightening? | In most places lightning is just to uncommon/unpredictable. Spending the money to build an infrastructure to collect that energy just doesn't make sense for something that's so inconsistent.Let's say we have electrical storage [batteries], and some input device for the lightning to come into. Lightning happens very fas... |
When I'm sick, why does masturbating temporally decongest my sinuses? | Does this work for girls? Because I'm severely congested at work and can't wait to go home and try |
Why after I wake up is my mouth/tongue filled/covered with white gunky stuff that tastes bad, what is it, and how can I get it to stop happening? | I'm no expert on this, but I've noticed the white stuff form after I eat something hot for dinner. Maybe dried up / dead tongue cells? |
What causes the angles of the 'cross' shapes from bright objects in photos (see attached image) and why are they all at that particular angle? | The answer is diffraction and aperture shape of the cameras. Here's a neat minutephysics video about the subject: _URL_0_ |
How come Videos (e.g. Maxed Graphics) do not require the same processing/rendering as the game? | It's because when you're playing the game, your computer is actually creating the images. It knows where the players, vehicles, buildings, scenery, lights, etc. are, and it has to figure out what it looks like from your characters perspective given all that information. It has to figure out what colour each pixel shoul... |
What is a FLAC file and what is the differences between it and an mp3 file? | FLAC is useful for an archival format. You will lose no information and get the benefit of a filesize smaller than the original CD. With today's storage costs being so cheap you can keep your music in FLAC on your home pc/NAS for permanent storage. From there you can convert these FLACs into MP3s for your portable musi... |
Why does our skin have any amount of electrical resistance? | I kinda assume you mean why the resistance isn't really small, considering we're a bag of salty water? If this is what you mean, it's because we're a BAG of salty water, not just salty water. Skin is dry, and doesn't conduct too well, even though what's inside conducts reasonably well. But if you're skin is wet, you te... |
Why do human women need so much work put into giving birth compared to other female mammals in the wild (hospitals, drugs, surgery, etc.)? | They don't *need* it. It just increases the chance for an uneventful birth. Before Caesarian sections and other medical interventions women and babies often died.The relevant wikipedia page is on [Obstetrical Dilemma]. It "refers to two conflicting trends in the evolutionary development of the human pelvis where the tr... |
What is the big deal with red velvet anything? | Red velvet is basically a whole other cake when it's home made. EDIT: Buttermilk frosting is best. |
why companies use instant & mail in rebates instead of just lowering the price of the item. | Also, they will do things like require that you include the original upc code from the packaging and if you throw out the packaging before knowing this, you're screwed. Happened to me recently on a monitor I bought. |
Why do banks require a credit score before issuing a mortgage? | Your credit score *is* your ability to make payments. Just because you currently make money doesn't mean you're the kind of person who actually pays their bills. It's proof that you are responsible with *other peoples* money. |
Why have desktop app stores not gotten similar development as mobile app stores? | Mobile devices make it difficult to download apps from random places, like someone's website, and easy to download from a centralized store. This means that there is some exclusivity to mobile devices, and that they have things like ratings, etc. Desktop systems are different because you can get an app from anywhere fr... |
Why do companies still make the pressable buttons on the lid for fountain drinks if they aren't used? | When aren't they used? I see them used all the time, at the very least to indicate which one is diet |
Klein bottles in the 4th dimension | My interpretation is if you think about the cross section of a Klein bottle along it's length: it's a series of circles. If you made a gif that cycled through plotting one circle at a time, you see a pattern that was a circle moving up and getting larger, then tilting over, narrowing and coming back down before going b... |
Why the United States should support the uprisings in middle eastern countries. | There is a great deal of debate on this. One the one hand we are experiencing human rights tragedies in Syria, on the other hand nobody knows what will rise from the ashes once Assad's regime is gone. It is important to note that of all five AS countries only one. Tunisia, has formed a democracy. Libya is still in disa... |
Is it possible to blind yourself permanently by just staring at the sun? If so how long would it take? | Definitely. Noon at the equator? I'd guess less that 5 minutes. Edit: may take longer. Here is a link. _URL_0_ |
Why does it take so long after changing the quality on youtube for it to actually take effect? | The YouTube player has already loaded a good chunk of the video that you haven't seen yet - something like 30 seconds to a minute. Rather than downloading the same chunk again in higher quality, it just waits until the next time it downloads a chunk, and downloads *that* chunk in high quality. |
What is the benefit of running Linux on a Chromebook? | Chromebooks are cheap, low-power systems. Linux, being free, helps keep the cost of the system down. A retail copy of Windows is over $100 - that's a lot of money when you're selling a $150-200 system. Even if you assume that companies are getting a deep discount, it's still a large percentage of the price - an issue t... |
Why did we have to learn farm animal sounds as a kid? | It's not about learning farm animal sounds per se, it's about basic association. We're trying to get the neurons in their little growing brains to fire using basic logic and recall.In addition to some of the other comments, animal sounds serve as a scaffold to learning animal names. Children often take longer to learn ... |
Who is Lucy the Australopithecus | Dude you literally click the google doodle and it tells you. She's a very-intact fossilized early human ancestor. Finding her was a big deal for the anthropological community. |
How would someone 'think' without knowing any language? | Differently. I would imagine a deaf person could think in terms of sign language for example. But also, you don't need to think in terms of language at all, and I'm pretty sure you don't either. Sure we can have an inner monologue, but most of your think probably isn't in terms of sentences and words. |
Why does Netflix have to pay the likes of Comcast or Time Warner to have their videos delivered smoothly to the consumer? Doesn't the consumer's payment for high-speed data cover this. | That was/is a central point in the argument against internet fast lanes, since it was shown that ISP's were also slowing Netflix traffic down. _URL_1_ I agree that it is in essence double dipping by service providers who also have conflicting interest as content providers. The whole thing is a shitshow. We will see how... |
Why is Julian Assange still in the Ecuadorian embassy? | Isn't he running for office in Australia? How does he plan on doing that from an embassy across the world?", 'Keep in mind that Assange is a criminal in the UK. He was given bail under certain conditions. Running away to a embassy obviously violates these. So he should be prosecuted there. He reason he gives for not wa... |
Why do the waitresses at Hooters wear those ugly thick brown stockings? | I'm guessing because hooters started in the late 80's/ early 90's and that was a more conventional look then .along with those stupid huge white socks.My sister is what I call a hooter girl for life. She says those are actually the same kind of stockings that dancers wear which hold your legs better, therefore helping ... |
If a UFO enters our atmosphere from outer space, why don't we see it light up like a fireball like when we see a meteor? | My thinking is that any alien race capable of constructing a craft that can make it here from parts of the galaxy unknown, are probably fully capable of slowing their descent to a planet's surface so as to avoid causing a scene. |
Male porn actors make much less than female porn actors, yet why does the former not advocate for "equal pay?" | Real eli5 aswer: Male porn actors are the highest paid in the industry. It's just not the male porn actors who bang women. |
How do Baristas make Latte Art? Does it take a much greater amount of skill or some equipment, or can I do it at home? | You can do it at home with a bit of arm-work and a measuring cup . You need a cup with a spout, milk, a whisk of some description , a bowl mug preferably, and that mug to be filled up halfway with black coffee. Steps:1) Pour about half a cup of milk. It doesn't have to be too much, just enough to fill up however many c... |
How can a machine like a coffee maker heat up a room temperature liquid so quickly but a chilling effect can't be done as rapidly? | So the best way to heat up a liquid is to expose it to something that's already really hot. Heat energy will then transfer from that hot object to the liquid, and Viola! your coffee is hot.This also works in the opposite way, if you expose your liquid to something very cold, then the heat energy transfers from the liqu... |
What differentiates regular anxiety from having an anxiety disorder? | Generalized anxiety disorder is categorized by extreme anxiety and no particular reason for the anxiety. As someone who has been crippled with awful anxiety so much that I have been bed ridden for days and have no idea what I'm anxious about. It's not like your typical anxiety over finances or a job interview. It's a s... |
What physical evidence do we have that atoms exist and they look like what we think? | Other people have mentioned specific evidence, but it's worth keeping in mind that in the last 100 years a very large chunk of physics and chemistry has been done under the assumptions that atoms exist, and all of it has been succesful. What are the chances that atoms are actually a fiction and we just got lucky to inv... |
Why do so many Sci-Fi aliens have British Accents? | It's just a lazy way to distinguish that they're 'foreign'. They have to set them apart somehow. Make them obviously not from around here. British accents sound more proper to American ears apparently. For some reason a British accent also has come to be associated with intelligence while naive at the same time.Easiest... |
Why is 100ºF a really hot day when your body is at 98.6ºF normally? | It's a hot day because your body has problems getting rid of all the heat it produces due to the environment being even hotter. |
Why has the mainstream music for the last 10-15 years been mostly about sex and partying? | What makes you think this is a new phenomenon? It's not. [Mozart 1782] [Lucille Bogan 1935] [Stuff Smith 1936] [Chuck Berry 1972]", 'Because the Beastie Boys fought for your right for this sort of thing.It's been a lot more than 10-15 years. |
Why do you feel your heart beat in hurting body parts? | If you place your fingers on your wrist or at the place where your neck meets your jaw, you can feel your pulse. It beats at the same rate that your heart does. All arteries, big and small, have this pulse because their walls recoil , but normally it's at these points that it's most noticeable, because the arteries are... |
Why is my laptop's time estimate of how much battery I have left always so incorrect? | Many reasons, one is it's constantly changing because you're constantly doing things on your computer. Opening new tabs, posting, doing anything on your computer uses more power than it just being idle. Videos and games use a lot of power. Everything on your computer will use varying amounts of power to do, so there ar... |
Why Chrome or Firefox doesn't block LiveJasmin and certain popups even though they are already set to block popups? | The web is written in different languages , but your web browser translates into web pages, layouts and web functions. Often times browser manufacturers block typical lines of code that result in pop-ups. But if a web designer circumvents those restrictions, then it's game. |
How does modern DSL achieve the speeds it does with using regular telephone wire/RJ-11? | remember the 14kbps to 36kpbs to 56kpbs to 112kpbs and so on and so fore? these are technology in it's receiving part of the modem. basically as long as the wire in telephone jack can maintain it's voltage without corrupting it's data over that distance, and the recipient can make it out of what the sender is trying to... |
how do traffic lights really work? | Its a combination of all those systems.Most Highways are on a computerized timer, they cycle thru red, yellow, green, arrow in a timed and specific manner. then you have roads that have peak and off peak times that cycle thru a timer during certain peak times then use a magnetic or infrared sensor to detect a car in of... |
What would be the ramifications of Turkey accepting that they committed genocide towards the Armenians in 1915? | I don't think recognition would do much of anything. But it would finally close up the wound that has plagued Armenians in Armenia and around the world. Not to mention the fact that Turkey wouldn't know how to handle itself and would probably do stupid enough things to finally be viewed as the backwards Islamic country... |
Why does squeezing your thumb supress your gag reflex | Placebo/distraction. Focusing on finding that 'one spot' on your thumb to squeeze provided enough distraction combined with the belief it will help that it can subdue some minor gagging |
How does a cracked touchscreen continue to function? | There are many layers of your screen, when you crack the outer glass you probably haven't damaged the capacitive layer, so the touch functionality continues to work. |
Why are Printers just as crap as they were 15 years ago? | They don't. You might be thinking about the cheap printers marketed for students or for home users. You can buy a good laser printer that can print tens of thousands of pages easily, but it'll be expensive and not really worth it for the occasional home use. Most people don't really need to print more than a few hundre... |
Why aren't ovens and microwaves a standardized so they are all the same? | No manufacturer wants to be bound by standards, because they want to sell based on how they're better than the standard. If every appliance were the same, what would they advertise? |
Self-immolation as a form of protest | Another has to do with the relationship between words and actions. Let's suppose you go *tell* people how angry you are. The fundamental action underneath your symbols is 'talking', as in 'I flapped my gums'. While this may, perhaps, lead to some talk about your talking, fundamentally it winds down. Alternatively, one ... |
Why do anthropologist say race is not a thing. | Great article to explain this by a guy named Jared Diamond called *Race Without Colour*. Really does a great job explaining the answer to your question. Here's a link to the article below. _URL_0_ |
What if the Earth spun the opposite direction it does? | If you were taking a shower you probably wouldnt notice much, If you were taking a bath You would have bathwater slop over the sides and you would have to get a mop out. This would be the Humorous answer. Actual answer would be this: If a stable change occurred while it stopped and reversed i.e not to much inertial cha... |
Is there a laser color stronger than the others? If so, why? | There is no 'stronger colour'. Photons with a shorter wavelength have a higher energy per photon. A source of light that emits a higher frequency doesn't produce a higher intensity of light than one that emits infra red, it emits the same intensity but using fewer photons. |
Why do people get such bad headaches when they stop drinking coffee everyday? | Caffeine is a stimulant which increases blood flow, dilates the blood vessels, and increases heartbeat. When caffeine is introduced into your blood stream the body releases an antidote of sorts that breaks down and metabolises the caffeine and returns the body to a less tweaked state. When your body gets a regular dose... |
Why do computers run into problems the longer they are on, and why does turning them off and on again usually fix the issue? | Let's just say you didn't do anything really stupid there are high chances it is just a random error. Most likely a bit in the memory flipped, which can result in blue screens or you might not even notice it . It doesn't have to be faulty for that it's just something that may happen. When you restart your computer all ... |
what would cause me to fail an HIV test for blood donation... twice? | Tests aren't perfect, they can and not too uncommonly do return false positives. It's not inconceivable that you just suffered two of them in a row. Can't speak authoritatively on this, but I'm sure there's also just some people with a physiology that more readily fools these tests - just more prone to having non-HIV s... |
Why after hundred years of flying airplanes, when communicating with towers the level of audio distortion and compressing still sucks to this day? | For a number of reasons, airplanes use radio instead of alternatives . Radio units can operate independently , they're fairly easy to operate and power, and they work in adverse conditions. At the frequencies used for air traffic with amplitude modulation , you're not going to get crystal clear audio, particularly if y... |
- What are some real repercussions that the UK could have if Scotland leaves? | A big rightward shift in British politics. This will make the north of England get very noisy indeed, especially if Scotland's brand of social democracy is successful. |
What is Steam video gaming and how is it different than other gaming platforms? | Steam isn't a gaming platform, it's a digital distribution platform for video games. You use it to buy, install and play games on your PC. |
Why holding your breath in dream makes you hold your breath IRL? | Apparently this sub does not allow answers which are one sentence long. So here's an additional sentence to pad my answer, which is a sincere one:I think you may just have sleep apnea. Maybe see a sleep specialist. |
Why do smaller animals have faster heart rates than larger ones? | It's to do with metabolic rate and only concerns mammals. The 'rate of living hypothesis' applies to all mammals except humans. Despite the vast differences in BPM and life span, most mammals average a similar amount of total heartbeats in their lifetime: around 450 million. Thanks to improved medicine and hygiene over... |
How is Unemployment Rate around 5% yet it feels 10x harder to land a good job than a decade ago? | Everything thats mentioned, and it also encompasses all jobs. It doesn't mean that its a job that would allow you to live at the lifestyle the job you had prior allowed you to, as well. Plenty of fast food and other jobs that pay minimum wage or slightly better are available. It doesn't mean people want them, obviously... |
What makes some things like Stradivari violins the best? (Insert anything that's old and considered superior) | For violins specifically, research has shown that age doesn't correlate with quality. Blinded audiences can't tell the difference between new and old. Age does change the sound though, as the older wood sounds different. |
Why can't people with a primarily asian dialect understand the difference in our "L" and "R" sound? | This is primarily a Japanese thing. [Note: For the following links, play the sound on the sidebar to get the idea.] In [カラオケ = karaoke] the 'r' is pronounced as an [Alveolar flap]. It's a weird way to say 'R' in English, but we will recognise it as an R sound. However, In words such as [こころ = kokoro], the 'r' is said a... |
How does Family Guy get away with all their racist jokes? | * Freedom of speech. * Freedom of media. * Money.
