What is happening on a cellular level that causes insulin resistance?
There are receptors on each cell that are responsible for pulling insulin into the cell from the blood. Those receptors stop working or work inefficiently which causes insulin resistance. When the cell is exposed to lots of sugar, all the time, it becomes less sensitive and less efficient at moving insulin into the cell. It's hard to ELI5 without going into hormones and other factors, but the jist is when the cell is constantly bathed in sugar it messes up the transport of insulin into the cell.
Why is it generally harder to sleep when "trying"?
You're right in saying that overthinking and anxiety interfere with falling asleep. When you "try" to sleep, are you also worrying in the back of your mind that it won't work or that it will be harder to sleep, as you stated? This sounds like anxiety, which could explain why "trying" to sleep keeps you from actually sleeping. In addition, for patients who have a lot of difficulty sleeping, we often find that they have a habit of thinking too much or worrying while lying in bed. This has the effect of associating lying in bed with worrying instead of sleeping, which will interfere with your sleep every time you lie down in bed. The solution to this is to undo those associations. Source: I work with patients with sleep problems as a part of earning my PhD in Clinical Psychology.Probably for the same reason it's harder to float when you're trying. Or orgasm. It's one of those things that requires *not trying* to accomplish; all of them require genuinely relaxing your muscles and not being anxious.
Why can't the United Nations overthrow North Korean's dictatorship and rehabilitate the ~25 million people with government funds?
To start, the UN has no authority to do that. the only binding resolutions that come from the UN are from the Security Council, of which China is a permanent member with veto authority. Since China doesn't want a failed state on its border, they will veto any action to intervene. Second, who's going to lead it? The UN has no military, and Peacekeepers come from the active militaries of other nations. Very few people would be interested in getting involved in a massive ground war in Asia. Third, who's going to pay for it? We generally discourage pillaging these days, so you can't raid North Korea for the funding and I doubt the U.S., NATO, Russia, or South Korea want to do that. Fourth, what happens when North Korea goes all out and nukes the invaders? Or decides to shell Seoul with conventional artillery, turning it to rubble? The world would have to rebuild two countries. Intervening in North Korea is simply not feasible. It'll be a big enough disaster if the regime collapses on its own, let alone through forced occupation.
Why a Catholic priest would find molesting a child somehow less offensive to the church than intercourse with a woman. What exactly is the logic here?
The whole "pedophile priest" thing isn't really about the Catholic faith. It's more to do with the sickest of pedophiles and their ways of attracting young boys. Really sick pedophiles like to get involved with things like churches, little league sports, and the Boy Scouts because it puts them around young boys and makes someone they can trust, and a lot of these people are the last you would expect to do such things. Of course, the Catholic Church is kind of an exception given their covering up of it, but at the core it has nothing to do with Catholicism. In fact, a lot of real Priests actually like the fact that the media has opened up the scandal so that it riles people up about it by putting it in the open, so they can hopefully get rid of the problemJust about any Catholic priest would find molesting a child far more offensive. Only a small few are actually pedophiles. What is sick is that so many of them find embarrassing the church more offensive than either.? Where are you getting that that's the case? No one would agree with what you just wrote. You're making a very strange assumption here. The scandal in the church isn't that some priests were molesters, but that the church as a global institution responded by covering up the situation and transferring those priests into new parishes where they continued to have ample access to children. In some cases, molesters were repeatedly transferred.
Why do rings make your skin green?
Rings generally do this because because of a chemical reaction between the metal on the ring, and substances on your hands . The reason it happens with some rings and not others is due to the type of metal the ring is made from/plated in. Silver is very common in rings, and readily oxidizes when it comes into contact with acids on your skin. The products of this oxidation reaction then rub off, and are left behind on your skin, [here] is a good example of oxidized silver! Copper is the metal that when oxidized, causes a green coloration. In some cities, some buildings have roofs made from copper, [here] you can see the green oxidized copper, and the brown clear patch of copper at the front of the roof. The same thing is happening with your ring, just on a smaller scale! Other metals, like gold, are far more stable and don't oxidize as easily, so they don't leave a mark.
Why is blue such a prominent colour in Italian sports kits when there is no blue on the flag?
As far as I know it was because it was the colour used to represent the royal family and the colour in the coat of arms.Blue is the colour of Savoia, which was the ruling family in Italy from 1861 until 1946. During that time, the Italian flag always had Savoia's coat of arms on it.
Why does food taste different when sick?
The taste of a lot of foods is influenced to various degrees by smell. So if your nose is clogged from being ill, your food will taste different.
Why can't I curl my pinkie finger (little finger) without curling my ring finger too?
Mostly because you're used to it. If you trained on bending your pinky without bending your ring finger, eventually, you'd be able to do it.
how come when I (a male) shave a portion of my legs, it becomes irritated when a female shaves their legs it's smooth and there is no irritation?
You might be using a dull razor or not enough lubrication . Women can get irritation from shaving. Have you ever seen a woman shave her legs? If not then how do you know they don't get irritation?
How do anti-shoplifting towers at the entrance of stores work?
What you're referring to is what's called an RF system, short for Radio Frequency. Things that the store want to protect will contain a small disposable electronic device called an RF tag that will activate when it gets in range of a radio signal at a specific frequency. This frequency is produced by either one of the towers or a hidden device in the door. Basically, the initial radio signal creates an electric current in the tag which powers its electronics, thus activating it. By activating, it begins transmitting its own radio frequency, which is picked up by the tower. Whenever the tower detects that frequency, it activates the alarm sound. The RF tag can be either deactivated or destroyed at the checkout. That's what the cashier is doing when they rub the item on the odd looking pad at their counter.There are a couple of different designs, but one common one is the use of metal strips of precise lengths. An electromagnetic field is used to create a current and therefore another opposing field within the conductive strips in the tag. The electromagnetic field is the manipulated in such a way as to create a resonant movement in one strip that impacts the neighboring strip, which in turn impacts the electromagnetic field of the strip itself. The sensing towers then detect this resonance in the electromagnetic field and can conclude it was produced by a tag, activating the alarm.
Why do some companies put coupons on their products that give the customer say for example an automatic $2 off? Why not make the price $2 cheaper?
Finding a coupon for a discount makes you feel like you're getting a deal. If the price were simply lower, you wouldn't notice the difference. Consumers are more likely to spend money when they know they are saving money.
When Yellowstone is called a supervolcano, what do they mean?
> What part of Yellowstone is the acutal supervolcano? [Nearly all of it] Yellowstone is a gigantic caldera. That's when a bubble of magma forms under the surface of the earth. It's too wide to actually form a volcano and instead forms a [peak around the edges] It's about 1,500 square miles of land. There's no way to tell exactly how accurate the death and doom stories are, but it's a sure thing that it will be a global event and will reshape civilization as we know it.
Why don't bugs bleed red when they explode on my windshield?
Bugs don't have blood. Bugs have hemolymph. Hemolymph serves as both blood and the other fluid that surrounds cells in our bodies. The color difference comes from the molecule that binds to oxygen. Blood contains hemoglobin, an iron-based protein that binds to oxygen. Hemolymph contains hemocyanin, which is copper-based. When we bleed large arthropods like [horseshoe crabs] we can see that hemocyanin gives the the hemolymph a blue, not a red color. Not as noticeable when you squash bugs because other tissues are mixed in with the hemolymph.
Why doesn't the US update their paper money to a more secure format?
> Since the superdollars were first detected about a decade ago, the regime has been pocketing an estimated $15 million to $25 million a year from them. That sounds like a lot of money, but compared to the $1 trillion in cash circulating in the great ocean of commerce, a few hundred million is chump change. Although costly for small-business owners who unknowingly accept a bunch of forgeries, counterfeits probably won’t bring about a crisis of faith in our paper money anytime soon. This paragraph answers your question.
Why is it that I can hold my breath for like 30-45 seconds in a pool but in the shower I can't last five seconds while washing my face beforebi have to gasp for breath?
This is likely related to something called the [mammalian diving reflex]. When cold water contacts your face, your heart rate immediately slows by 10-25%, and the blood vessels to your extremities begin to close off. This reduces the oxygen being consumed by your body, and leaves more available for your vital organs and brainI have the same type of thing happen when I'm swimming. I found that when submerged fully your instincts to hold your breath outweigh your "need" to gasp for air. Whilst in the shower you aren't fully submerged and your instincts to breath increase. Here's an experiment. Try sinking to the bottom of the pool and holding your breath. After finding the time for that find the time for holding your breath in a shower. And then in a bathtub submerge your face only. I found these resultsPool: 65 seconds Shower: 32 secondsPool: 54 seconds. Results vary depending on lung capacity, health and fitness level and age. My results are on a 20y.o M, smoker, distance runner and diver. I found that full submersion results in a more relaxed muscular state which provides for less oxygen consumption it's kind of like meditation uses slower breathing and less oxygen consumption. Sorry to the OP for the long response. Just wanted to share my findings after reading the post and doing an experiment myself.
If airplane cabins are airtight and pressurized, why do my ears pop when the airplane ascends/descends?
The cabin is not perfectly airtight, it has vents. As the plane climbs, the pressure is allowed to fall naturally until around 8,000 ft after which air is forced in to keep the pressure up at the 8,000 ft equivalent. There's always fresh air coming in, it's not fully recirculated : if the plane was airtight, we'd run out of oxygen before we got to our destination.
Why do schools adopt a zero-tolerance policy and what do these policies generally dictate?
Zero tolerance policies are there for the convenience of dishing out discipline & avoiding complaints about unequal punishment being dealt out. For example, a zero tolerance policy about fighting means that when you break up a fight, both people are automatically guilty and punished. The teacher doesn't have to figure out what's really going on & can get back to teaching. The school can't get accused to going easy on a popular kid or somebody whose parents are important in the community and having double standards. At least that's the idea behind them. Whether they actually work & improve the learning environment is up to debate. Just remember that you only ever hear about them when something goes horribly wrong & it becomes newsworthy.Equal punishment is silly. Why punish a student who is defending themselves in a fight?
If dogs and other animals do not have to brush their teeth daily, why do humans?
Hi, first, animals don't eat candie, they don't drink cofee, don't smoke, And they only live a few years while we can live up to 100 years old. Sorry for my english ;)
How are restaurants able to keep soda carbonated and ready to serve?
They don't. Inside the soda machine are containers of syrup and a tank of compressed CO2. The two are mixed together at the time the drink is dispensed. On a small/home scale, you can look at a SodaStream system to see how it works.There are tanks of CO2 that are kept with the syrup for the sodas. When you order the soda, a machine pumps the two ingredients together in proportion and thus soda.
Why is it that sitcoms and other television shows can show people abusing alcohol, but advertisements can not show people drinking?
Portraying alcohol abuse as normal in entertainment is not obviously less harmful than doing so in advertisements, but advertisements are not as strongly protected as noncommercial speech under the current court's interpretation of the First Amendment.
Today Earth is closer to the sun than any other time in it's orbit. Why are we not more significantly affected by this?
At its closest the Earth is about 147 million km from the Sun. At the furthest 152 million km from the Sun. That's barely anything.
Why does AIDS keep getting cured like once a week?
There's lots of things that may kill/destroy a virus. The trick is finding something that doesn't also kill/destroy *you*.
If there was nothing, how was there a "Big Bang"?
Lots of theories out there, but the simplest and most correct answer is that no one has a clue what may or may not have existed before the big bangIt's not that there was "nothing", it's that it's impossible to determine what exists outside our universe. Sometimes people say there was nothing because it's as good an answer as any. It's unknowable.The key to understanding it is to understand that it's not a meaningful question. The way I heard it explained was to think about rewinding a video, you spool back through the film then through the trailers then through the annoying 'don't buy pirate videos' lecture then there are some logos then maybe some black screen with some numbers written on it then some static, then the tape stops. It's not really a meaningful question to ask what is 'before' the static. or what is 'before' Track 1 on a CD. Of course the more technical you get, the more precisely you can describe the leader tape with no magnetic stuff on it or the data header on a CD but there comes a point where it is not meaningful to ask what was before.Its a common misconseption that the big bang was once a singularity and it exploded into nothingness. It's true that the observable universe was once much smaller, but not the whole universe. Think of a infinite field. No matter how much smaller you make it, it keeps on getting smaller. You expand the field. Because you have a infinite field, it just keeps on expanding. The universe has already existed, only much more compact. Then everything started to stretch and getting bigger. MinutePhysics said it should be better named "everywhere Stretch". The fucking people at big bang theory poisoning the world with this misconception. The universe was never a singularity. It didn't expand into nothingness. That's why most scientists find the show laughable and cliched.Technically there was always supposedly a singularity. I've never been educated to believe there was *nothing*.
How we measure the measurements themselves
First keep in mind that units are arbitrary - they don't have any impact on the results of experiments. Units are just a way to put a number to "that far" or "this long" or "this much." With that being said, units: -The second is defined by to be 1/the frequency of the light emitted by a particular process in cesium-133. -The meter is defined to be the distance that light travels in 1/299,792,458 of a second. -The kilogram is weird, in that it's defined to be the mass of a hunk of stuff called the International Prototype of the Kilogram . This is actually slightly problematic because the IPK is losing a small amount of mass over time. Units have gone through lots of evolution over time. For example, the second used to be defined in terms of the Earth's orbit. And a long time ago, people used very awkward units like the cubit, which is defined to be the distance between the elbow and the tip of the middle finger. Obviously that's not a very good unit system because it varies from person to person.If you have a pendulum in a clock, the length of time it takes to swing depends on the length of the pendulum. A pendulum that swings for one second is a metre long. If you could have a cube of water that measured 10 x 10 x 10 centimetres, that would be a litre of water. A litre of water weighs one kilogram If you heat up a millilitre of water by one degree Centigrade, the energy used would be a calorie. I am sure there are more equations but I can't think of them off the top of my head.
"No approved therapeutic claims" on ads.
Their claim hasn't been verified in any scientific way. If I gave 10000 people a sugar pill and 1000 of them lost weight I could legally claim that the pill helps with weight loss. It wouldn't make the claim true, and the results might not be repeated in a larger sample population. The disclaimer would keep people from winning lawsuits against me when they don't get the results they hoped for.It's been a tough battle for science-based medicine, and it continues so. In the USA, the *Food and Drug Administration* must approve all medicines and supplements, but the only criteria for dietary supplements is that they do no harm. They don't need to show efficacy in order to be marketed and sold. This encompasses all herbal and homoeopathic remedies and much much more. Finally legislation was passed to add clear disclaimers of non-efficacy. Because it is a battle with a multi-billion dollar industry with a lot of political power, change is slow and passing a law reforming the FDA's power is very difficult. One happy day in the future, their sale as remedies may be banned outright. Also pay attention to the exact wording of these ads. They will get shut down if they claim any specific cures, but if it's "strengthening the immune system
Why is the 'highest quality' of audio cables gold plated when silver is a more conductive material?
Gold is more corrosion-resistant. Silver is very quick to tarnish, particularly if people touch itAh I can actually sorta answer this. The reason behind that is because gold is a very stable element, and as such does not degrade easily. Silver on the other hand tarnishes quickly over time, but gold will keep its structure for a long period of time.
What changes (if any) occur to the circulatory system when someone becomes an amputee?
At first, your blood pressure would increase, as the heart is working just was hard to push less blood a shorter distance. But your circulatory system has a feedback system that monitors both how much blood is needed, and what pressure it is at. It would eventually recognize the you were getting plenty of blood, and could lower the blood pressure by dilating arteries.The changes are generally trivial, don't forget there will often be an appreciable amount of blood left in the amputated limb, in the capillaries for sure. The body will, normally, adjust quickly, its detectors will cause the heart to pump less strongly, within minutes, excess water from the blood will be quickly eliminated, less blood cells will need to be produced to replace those normally dying. Basically, it's no big deal.Yeah but lets say I am trapped under a rock, cut off my arm, cauterize stump, and never visit a doctor: what happens to the ends of the veins then? How would they find each other in order to complete the circuit? In other words, how did they do it before modern medicine?', "I'd like to know what happens to the circulatory system/veins/capillaries when a leg is amputated right after the hip for example. Does the system work itself out or do doctors have to adjust them?
What causes that bubble/cloud around fighter jets when they are traveling at extremely high speeds?
It's probably a [vapor cone]. Basically, when a jet goes faster than the speed of sound, it creates areas of extremely high and low air pressure around the jet. Some of these low pressure areas lower the pressure so much that the water condenses out of the air.
Civil rights vs Civil liberties
The very easy way to think of it is that Civil Rights refer to the idea of all people having equal treatment, especially being free from discrimination based on factors like race, sex, etc. Civil Liberties are those freedoms protected explicitly by law. First amendment rights, etc. There's some overlap, obviously.
Why is there a scandal in South Korea right now? What happened?
It was discovered that the president of South Korea has been getting advice from a "psychic" claiming to be able to channel the spirit of her dead mother, and that not only has the president been giving federal money to this woman, but that this "psychic" has been behind pretty much every decision they 've made while in office. The general public are not pleased with this.
What does "70mm" mean in film, and why are people excited about it?
"70mm" means that the film on which the image was collected and later projected is itself is 70mm wide. Think of older cameras that used 35mm film as a standard, but up this to 70mm and apply it to cinema. The reason 70mm film gets people excited is that the film allows for greater image resolution. Larger format films spread the image over a wider area, which allows for more detail to be collected by the pigments in the film. This gives a better final image. This is why lots of portrait studios used to use large format cameras since they generally give better images for the same film stock, and smaller size and subsequent "movability" was not necessary. If memory serves, 70mm can give films a really wide aspect ratio without loss of image quality. This allows you to do really epic film-making in a style along the lines of Lawrence of Arabia, Ben-Hur and the likeIt's the width of the film. The 70mm film has almost 4 times the surface area of 35mm film. With film grain as the resolution limiting factor in the image, you get the equivalent of 4 times as many "pixels".
Why is the Great Barrier Reef bleaching, what does that mean, and what impact does that have on global biodiversity??
Imagine coral as a landlord - it owns property , inside which small organisms cohabit. It provides them with some chemicals required for photosynthesis and a nice place to live, it in turn provides the coral a source of energy. These microorganisms are what make corals different colours. When ocean conditions alter , the organisms abandon the coral. Since they provide 90% of its energy, the coral dies. Imagine if your mitochondira couldn't tolerate your body anymore - you'd die almost instantly from the lack of ATP production, no matter what you did. Other factors affect the microrganisms inside them like chemicals, water clarity etc, but heat stress is the singular biggest killer. It will have catastrophic effects on biodiversity - one of the principal reasons water in tropical locations looks so beautiful and clear is that its actually kind of dead - heavily lacking in plankton. Coral reefs function as oases of sorts, providing a vibrant basis for an ecosystem which massively increases local biodiversity. Without them, almost every species adapted for reef life will either become severely engaged or go extinct. This will likely have knock on effects up and down the food chain ). Biodiversity on land will likely suffer a knock on negative effect, as the primarily poorer communities surrounding many of the worlds reefs can no longer rely on fishing to substain themselves and must increasingly use land based resources. There is some hope from a biodiversity perspective though. Some corals have been found that occupy tidal pools. Given the dramatically reduced volume of these pools, they undergo wide thermal swings over the course of each day, without ill effect. It might be possible to either modify existing coral, or transplant adapted coral and replenish the reef.
Why did early pistol and musket designs have such unergonomic looking grips?
Ergonomics as a science hadn't been invented yet, and guns were mostly handcrafted pieces, so each gunsmith was kind of just doing his own thing. Ergonomics also isn't all that important when you have a gun with no sights and you're only expected to fire a couple rounds a minute at most.
How come using better sports equipments isn't considered cheating?
It is considered cheating. There are very strict regulations about what can and cannot be used, and what types of modifications can be made to equipment. So, for example, baseball bats have to be made a certain way. If you make them out of a different material, or make them shaped different, or anything else that would give you an advantage, it's considered cheating.Equipment does not make someone a better athlete, it allows them to better use their skills. A good shoe will allow a runner to better grip the track while not weighing them down. However, the shoe does not make them any faster by making their leg muscles bigger or improving their air/blood flow. Equipment is also regulated. The equipment must be within certain dimension and be made of certain material to be considered legal within the sport. Using equipment that is not allowed is considered cheating.In non-professional sports, it's unlikely that using a thousand dollar racket or swimsuit or whatever is really going to be the deciding factor. In professional sports, it's assumed that anyone participating is going to be able to afford the best stuff; if they don't use it, it's because they prefer not to.
Why does is Cyanide so toxic if its just Carbon and Nitrogen?
The atoms that make it don't matter in this case. What matters is the shape of the molecule they make together, and how that mixes with other shapes in the human body. Imagine that some molecules are locks, and others are keys. There is one particular lock that is necessary for your cells to produce energy, which you need to survive. When the one molecule that is shaped right fits that lock, it allows the cell to produce energy. Then it comes out, and you can do it again. Cyanide is like a mis-cut key. It fits in the lock, but doesn't produce energy. Worse, it gets stuck, and won't come out. When this happens to enough of the locks, you no longer produce enough energy. That means your muscles stop working, which stops your lungs, heart, etc.
Why do professors continuously write exams with extremely low averages and then curve, rather than write easier exams?
if they set the bar too low, they wouldn't get a representative sample of what the class understands. For example: if you're in calculus class, and the test only has "what is 2+2?" on it, then obviously everyone will pass. Which tells the professor nothing. If, however, there is a wide sampling of problems of varying difficulty, the professor and his staff can accurately gauge where the students are having trouble. Effectively, this is one of those areas where failure is probably more significant than success - having the entire class fail on one chapter tells the professor that he or she maybe didn't do a good job explaining, or the TAs need to spend more time on that area. They wouldn't know this if the tests were so easy that everyone would pass. To say nothing of the fact that people need to be challenged in order to grow.It shows Profs. the full range of what the class knows. If tests were easy enough for 1/2 the class to ace, then you only know they've mastered that minimal portion of the material. If everyone is stretched to their limit, then the profs. have a better idea what the class learned and what they didn't. College classes are not meant to be training, where the goal is to learn a fixed set of informatio. Instead it's about exploring a subject to it's fullest to learn as much as you can in the allotted time. However, as college becomes a commodity, classes start to look more like training and less like education.
Why doesn't reddit have an official iPhone app?
We already have lots of apps that work fine, like alien blue etc. Reddit doesn't need to make an official one.
Why people talk to babies/dogs/cute things in a high pitched voice?
Lower pitched noises tend to represent anger and instill fear, while higher pitched tones tend to feel happy or nice . If you subscribe to evolutionary psychology, generally predatory animals like dogs will have low pitched growls while harmless animals like birds will have higher pitched noises. I'm not sure when or the evolutionary reason why this came to be, but I think that's where it stems from.
Rocket "Launch Windows"
"Launch window" may be set by multiple conditions. More mundane being a condition to shut off nearby naval and air traffic, which needs to be coordinated with appropriate authorities. The interesting part of this are relative positions of Earth and target of the mission. All planets, moons and satellites are always moving, and they are moving at different speeds, so they move relative to each other. Therefore there are times when trip with the same target will take less resources and times when it will take more resources to complete . Extreme example of this were Voyager probes ), which flew by Jupiter, Saturn, Uranus and Neptune. It could obviously take such path only when they were positioned ideally. If a mission is launched "outside of launch window", it means that the conditions are not ideal and it would need more fuel to fly where needed. But the margins are fuzzy, launching a mission to Mars few days after optimal date means a bit more fuel is needed, but launching it few months later increases the amount of fuel drastically. By calculating how much your rocket can lift, you determine the time limits applicable to your concrete mission.> What creates and ends a launch window? Usually it has to do with the orbital motion of their target , or their desired path through the solar system. If you are launching a probe toward Mars for example you need to get your launch mostly pointing toward Mars. If you wait 12 hours your launch path is now pointing the other way, which obviously isn't a good idea. Usually it doesn't really have anything to do with the weather, although of course the weather can be important. > And what happens if a rocket is launched outside that window? The rocket doesn't go the right way. Imagine you are throwing a baseball back and forth with a friend but you are spinning around in a circle at a constant rate. Can you just throw whenever? Of course not, you need to wait for the right time or you will be throwing randomly away from your friend.
The Kathy Shelton Rape Case
Kathy was brutally raped when she was 12 years old. Hillary Clinton was a lawyer in Arkansas. The defendant in the case asked for a female lawyer, the judge asked Clinton to be the public defender for this lawyer. Clinton reluctantly took the case and fought aggressively for the client and got a one year sentence and not for child rape. Many years later, in an interview Hillary Clinton laughed at some aspects of the case. Years later after hearing about the recording Kathy went public about how she was subjected to psychological reviews, could not bare children was traumatized from the questions by the defendants. Two years later the shield laws were enacted which prevented the kind of questioning of rape victims like Clinton's defense team had done. The controversy is 1) she laughed at the case 2) she or the defense team went overboard in questioning the victim. Source._URL_0_
Why is the OJ case iconic?
Well, it was a huge deal at the time. The coverage was unprecedented, and in fact it is credited as being the first "reality" TV - from the white bronco chase, throughout the court coverage.Imagine Peyton Manning being charged with murdering his ex and her friend. Then imagine Peyton Manning being African American. Then imagine it happening in a city where recently white police officers beat a black man for no reason. Imagine those officers walked away without significant consequences. Add in Los Angeles, a team of defense lawyers that are legendary, a racist detective, a glove that doesn't fit, and 24 hour television coverage for a year. Finally, Peyton Manning is proven not guilty where all evidence points to him. This about sums it up.
How did the medical community determine daily vitamin intake recommendations?
A vitamin is an organic molecule that the human body has \'forgotten\' how to synthesise: over many generations it was always present in the diet, so there was no need to produce it, and those pathways fell into disuse and finally stopped working. Minerals, meanwhile, are a way for the body to get the elements it needs, like iron and calcium - no organisms can synthesise those. Nowadays we do have access to a much more diverse diet, but that means that it's possible to accidentally not eat any foods that contain a certain vitamin or mineral. The medical community can work out a safe figure for how much you need by a simple method: how little do you have to be getting, for being given some of that vitamin to make you healthier? Many vitamins and minerals have an absolutely vast range of dosage levels between "gets healthier when given more of it" and "gets sicker when given more of it" - when you're overdosing on a given vitamin. So they just pick a value based on the best knowledge available. Yes, most people are not at any risk of getting too little of any vitamin in their normal diet. It's something to look into at particular points in life , or if you have an unusual diet .
Why did games from around decade ago have videos that played if you were idle in the menus?
They acted as a screen saver. Old CRT televisions would have an image burned into the screen if it displayed the same thing for a long time ). The video just stopped the same image for displaying for too long. These days, image burning isn't really a problem with LED and plasma screens.
Why are computer processors produced in a vinyl size disc form?
The silicon needed for the processors is produced as a huge cylinder, which is then sliced into these thin discs, called wafers. It's cylinder shaped because of a process called [Czolchralski process].
What is the difference between Chrome & Chromium, and who owns Chromium?
Chrome is a browser created by Google. Chromium is an open source browser based on Chrome. Chrome OS is an operating system made by Google, where the Chrome browser is the primary user interface. It is designed for lightweight devices that are primarily used to access the internet. Chromium OS is an open source version of Chrome. Chromebook as a laptop sold by Google with the Chrome OS preinstalled.Chromium is an open source browser that chrome is based on. As an open source project it is not technically owned by anyone, you could take the code of it and make your own browser if you wanted to. But as far as who did most of the work on it that would be Google. When Google decided to make a browser they decided to split it into an open source project and then a closed project which is based on the chromium code. The only major differences between chromium and chrome is that Google includes some components in chrome that cannot be included in an open source project like chromium for licensing reasons. This includes things like the PDF reader built into chrome and the Flash plugin, and support for certain video codecs as well as DRM protected content which is not supported in chromium out of the box. It also includes the Google updater which keeps your chrome install up to date automatically, which is not present in chromium. From the perspective of a normal user they are nearly identical, but since chrome has some features that chromium lacks, and tend to be a bit more stable since it's releases are tested by Google and other testers before they are pushed out you are generally best of using chrome.
Why do gas prices change daily, but nearly all other consumer products have a fixed price?
Consumer products don't have a fixed price. Rather, they don't have a fixed cost, but retailers usually mark them up high enough that the profit buffer is still there no matter how much the cost fluctuates. There's also the theory of the "menu cost" which holds that retailers incur some cost to actually change their prices, so they prefer to change them as infrequently as possible. Over time, consumer prices do change, usually going up owing to inflationMost gas stations make very little profit off the sale of gas. The profit comes from selling the drinks, snacks and smokes.
What is a Home Loan Repayment?
Your home loan repayment is intially calculated on principal and interest. Example: So if you're home loan is 250,000 - over a 30 years period the repayment will be 1500 a month. Of the 1500, 500 will be interest and 1000 will be principal which is the amount you're reducing the loan by. Most banks calculate interest daily and charge it monthly which is why it's better to dump as much as you can into the loan so your monthly calculation will be less interest and more principal. Then Check with your back again, some banks divide a weekly repayment by getting your monthly and dividing by 4 instead of 4.33.. this will mean that you'll actually get a couple extra payments a year. Confused? Example: Dividing by 4 means that your repayment will be every Tuesday, some months have 5 Tuesdays. Dividing by 4.33 means that they are calculating the repayment to happen on certain dates of the month, not days. For the curious - fortnightly payments also work to reduce the loan quicker if the bank divided by 2 instead of 2.16. Hope this helps.
Theoretically, what (if any) is the lower limit of density for solid objects? In other words, how not-dense could a solid object get?
To answer that, you would have to decide when to stop calling something a solid. [Aerogel] is hardly there at all. It's a solid, but probably only just.
Why does the DMV care how much I spend to buy a car from a relative?
Because the DMV is responsible for collecting taxes on the sale of a car from the buyer. Cars are one of those special items that are taxed even when bought used. Your relationship to the seller is irrelevant.Right, it's to collect tax and they have no way of telling whether it's the truth. It could turn up though in a federal or state audit. I doubt they'd care much if it was a junker and you'd owe the difference plus a penalty, but if you're caught misstating the value on a Ferrari or a car collection, you could get into some serious trouble.
Why does water dry out our hands?
Your skin has a layer of oils which it uses for waterproofing, making it more difficult for water to escape your tissues. However, it's not invincible, so enough washing can strip this layer. This allows water to escape from your tissues to the air more readily, drying it out, until your body has a chance to replenish the coating.Our skin produces special oils that mosturize it. These oils are what stays on windows when you touch them. Washing removes this layer, and once the water dries out, it leaves the skin dry until it can produce more oil.
How does it feel falling through a cloud while skydiving? Is it safe to perform such a feat?
As a pilot, I can advise that as a rule of thumb, clouds have turbulence. Not always bad turbulence, but I feel lik skydiving through them is asking. It some rough bumps. Just a WAG.why wouldn't it be? clouds are made of microscopic bits of water. it'd be the same as sticking your head out of the car while passing thru fog
what causes the leaves to get caught in a gust of wind and form a mini tornado of sorts for a moment or two?
Vortexes are common in turbulent flows, like you get with air of differing temperatures. For instance as warm air rises from the surface it may pass through cooler air above it, pushing it out of the way. So you have a rising low density column with heavier density air flowing around it, potentially giving you a rising rotating column. The only thing the leaves are doing is traveling in the moving air, and thereby making its motion visible.Leaves don't weigh a lot. Wind can weigh more than leaves. sometimes wind picks leaves up. wind flows in patterns. sometimes those patterns look like tornadoes
Does taking a double dosage of something have the same effect as taking it twice a day? If so or if not, how?
They'll have different effects. When you ingest something, the amount in your blood increases fairly quickly as it gets digested, then begins falling off as your liver/kidneys filter it out. But that filtering is sort of a proportional thing. Like, your liver will remove 15% of whats in your system every hour, say. So 15% in the first hour, 15% of the remaining 85% the second, etc. So when you ingest more often in smaller doses, it means the amount in your system stays in a narrower range. Doubling up once a day means a lot right after you drink it, and almost none by the time you're due for more.
If the hottest man-made temperature ever is 5,500,000,000,000C in the CERN, how come the lab and everything sorrounding it didn't melt down?
Think about the difference between the filament of a light bulb being at about 2550 Celsius vs your entire house being that temperature. Obviously that is the difference between business as usual and your entire house burning, melting, and exploding at the same time. That very high temperature at CERN was in a very small area for a very brief period of time. The total amount of energy was fairly small, just very concentrated at that instantTemperature isn’t the same as heat. Would you rather a teacup full of 100$ bills, or a bathtub full of 50$ bills? Same idea here, just because that was the highest temperature doesn’t mean there was much heat. That temperature was for so little time and in so small a spot.Same reason a campfire doesn't burn the forest down. There is a very little hot stuff, and a whole lot of cold stuff, which dilutes the heat before it can do any damage. It is likely the CERN experiment only heated a handful of subatomic particles to the temperature.
How do the citizens from countries like Canada and USA get the connections to join groups like ISIS or even the Peshmerga?
Through social media and "connections" that are met at gatherings, such as mosques. NOTE: This is not to say that all mosques are recruiting grounds for ISIS but it has happen.The same way that they get connection to organizations such as the Hell's Angels, or the KKK or Neo-Nazi groups. Those groups do have supporters, and those supporters look for people that are sympathetic to their cause, and then they prey on them. They feed them a stream of support that comes from their group, while undermining the support they feel from others. Until such a point as those people want to go join those groups overseas.
Why is it that 4G internet on my phone feels insanely slow, almost useless sometimes, but years ago, back when 4G and LTE didn't exist, 3G on my Blackberry felt fine?
It's because websites have put more content into their pages. If you tried to use your old 3G again, it would be painfully slow. Even though our computers are getting faster, the actual time taken to run our software is the same across the years. We keep building heavier software.
why do car engines vibrate more when in park?
When your engine runs, it doesn't deliver nice constant power. It's a series of captured explosions delivering sudden bursts of power, followed by a lag until the next burst. This is more noticeable when the engine is running really slowly, since the explosions are further apart. Also, the weight and resistance of the drivetrain helps to smooth out the explosions and make power delivery feel more smooth, but when the transmission is in neutral this extra weight and drag isn't present to help smooth things out. Finally, engines are tuned to run best at a certain RPM, when they are running significantly faster or slower than this RPM, they can run more roughly.
Why is it that television shows from Britain seem to appear different than American tv shows?
Couple things would give it a different look. First, they use PAL rather than NTSC. Pal uses 25 fps while ntsc uses 30 so pal will look more cinematic while ntsc will look more fluid. Also color encoding differences between pal and ntsc. When we in the U.S. watch a Britcom or other material produced in the UK, there will be some kind of conversion that takes place. The difference you see is mostly because of the conversion process. The above refers to analog signals. Digital signals typically look more consistent between US and UK. Take a show like The Graham Norton show. It looks like it's produced in the US. The colors are on, no frame rate adjustment All good. Btw the frame rate is due to the in-country electrical system. In the U.S., our AC runs at 60Hz. While in the UK, they run at 50Hz. So the frame rate is a multiplier of the AC cycles. If you're looking for less subtle differences, they spell things differently. So you'll see honor spelled honour; color spelled colour; and other spelling variances.
Why did using AM radio for music fall out of favour?
AM sound quality isn't great, but it travels longer distances. FM sounds better, but doesn't travel far. This is probably not an official stance, but I think AM - being sports and news talk primarily - has a smaller audience appeal, so reaching farther audiences is better for them as it expands their potential listener base; FM - being music - has wider audience appeal, but is typically tailored for a particular taste, and what genre makes good money in one market may not make as much money in another market, so it benefits FM stations to have a more concentrated market they can focus on.
Why do I get a weird tingly sensation in the bridge of my nose when something is less than a foot in front of my face?
I know exactly what you're talking about. I get this too, though don't know much about it either. The feeling will linger on the tip of my nose for up to a minute after the person or thing leaves that threshold.Are you a dude? If so, is it kinda like the feeling you get when something is not too far from your family jewels?Reading this post has given me this feeling. Can we get an an expert in here to answers this?
Why are "month end" sales so important to companies?
My take: we tend to procrastinate. If monthly target is 20 widgets, logic would state to sell 5 a week. Problem is, we bask in the month end hang over and drag our ass in week one, then struggle to make up for lost time in weeks 2 and 3. This leads to a balls out race into insanity in week 4. But don't sweat it, week 1 is around the corner and things will slow down again. Source: am in sales
As a broke, 24-year-old pizza delivery guy what can we as citizens do to help fight against internet censorship?
Honestly I question whether this belongs in ELI5. There really isn't a way to explain what the problem is without 'bias' or 'blatant speculation'.The most important thing to do right now is to remain informed and to write letters to your representatives giving your well-reasoned opinion why things like SOPA are bad for everyone. Right now, the important thing to remember is that there is *nothing* to be scared of, nothing that is awful and nothing that is censoring. There is merely proposed legislation which need to be watched closelyAccidentally fall into a cryogenic capsule, and wake up 1000 years later to have a series of escapades with your wacky group of friendsOrganize a protest of at least 50 people in your city , make 200 flyrs or so and hang theem around near very populated locations near you', "Well you can read up on various topics on copyright, censorship and the like. I'd suggest taking a look at Lawrence Lessig's books and Cory Doctorow. Both publish their books for free under the CC license on their websites.
What is really happening when you snap mentally?
Define "snap". It can mean a lot of different things. Like snapping from stress where you just can't take it or snapping as in waking up one day and killing 10 people?You're going to have to be a lot more specific. "Snapping" is a colloquial term, not a scientific or medical one, that describes a bunch of different situations. You can't get a single answer for what's going on because it a bunch of different thingsI would rephrase this question to "what is really happening when you have a mental breakdown"Typically, a "snap" is an episode fueled by emotion. Can't tell you exactly what's happening, but when people actually lose their shit, no, it's not a conscious decision.
Why do free range eggs have harder shells than the "conventional" kind?
Free range chickens have a more varied diet which contains more minerals. Or in short, because they eat bugs.I don't mean to hijack, but since we're on the topic- I've heard that free range eggs are not necessarily so, that there is a bit of deceit or exaggeration involved. Anybody here with inside knowledge or source of the real deal?
Why are some people attached to a particular sleeping position?
I would also like to know why I always end up sleeping on my stomach with my arms by my head, even though my arms fall aslep every time I do this. My scumbag sleeping brain never learns Because on my right side with my arm under the pillow and my head on the pillow with my left leg outside of the blankets is the most comfortable.
why is it that fire normally burns orange? Why isn’t it blue, green, or purple?
The color of a flame depends on what is burning and how hot it is. Most flames come from burning carbon based fuel and these things burn orange/red/yellow. The higher the temperature the whiter the flame. Other chemical substances simply burn different colors than carbon. This has to do with the amount of energy given off as something burnsYou can make fire with all those colours - it just takes specific chemicals. See [here] for more details with pictures.
Why were futurist so optimistic about the year 2000?
Futurists of the 20th century merely used the year 2000 as a distant, exotic-sounding future year. Their optimism was based on projecting their economic system into the future in order to demonstrate that the troubles of their time are temporary and that perseverance will lead to a greater good. The last time all the digits changed in the Gregorian calendar few people understood Arabic numerals. So 2000 being so tantalizingly close to their time attracted the imagination. Many others felt the world would end either by supernatural force or our own hubris. Making it to/through 2000 was something many saw as an achievement.
What is the advantage of being young when it comes to gymnastics?
Because the rules don't allow them to compete internationally below 16. Younger girls gymnasts can complete more difficult maneuvers than adults, performance peaks at 16 to 18 because 16 is the cut off. It's not bullshit, a large part of women's gymnastics events involves spinning the body . During puberty, women grow and develop in ways that mean more of their mass is further from their center of gravity. That means the same push by a gymnast results in fewer rotations for an adult than a smaller, less developed teen, so they get a lower difficulty multiplier and a lower score. But here's the words from [Daniela Silivas a Romanian Gymnast]: > You should know that I competed better at the age of 13 than at 17. I felt much better, physical and mentally. And [a gymnastics coach]: > When they're younger -- before they even hit 13 -- they hit their peak, especially top-level gymnasts", 'Many gymnasts are even younger than that. When girls enter their teens their body starts to change. These changes include fat reserves in particular areas that can make some of the routines they do very difficult.
How did plants appear on land when all life started in the ocean?
Just as with animals plants grew in shallower and shallower water then at the edge of the water then on the land. A gradual 'evolution' from aquatic to terrestrial.
Why computer viruses associated so strongly with internet porn?
I'm not sure about this, but I also guess that if you are watching porn, you are more likely to download pictures videos, Java plugins and even new codecs for watching those videos etc All that content can hold malicious code to attack your computer I guess.Porn is a very strong inducement. Click here to see famous boobies! Well, son, how did this virus get on your computer? I dunno dad, I was just doing my homework.
Why does the sun seem to burn hotter in the morning (ca. 10:00) than in the afternoon (ca. 17:00)?
1000 is only 2 hours off of noon. 1700 is 5 hours off if noon. The morning equivalent of 1700 would be 0700.It has to do with the height of the sun in the at 10:00 and 17:00. In the morning at 10:00am the sun is almost at its highest position in the sky. Because of this the sun radiates more energy towards us and the Earth. If the sun is not so high like at 17:00, there is less surface area for the sun's energy to radiate off of and thus it is cooler in the evening.
How is time an illusion
People like to think this, and *deep thinkers* come up with this on their own all the time, but time is actually a part of the universe, that exists with or without people. It is relative, but it definitely exists and has been mathematically proven over and over
Why is that James Bond movie called 'Quantum of Solace?'
It is also a term meaning "extremely small". The idea is that Bond is getting an "extremely small" amount of solace by hunting down and killing the people responsible for Vesper's death. Also the bad guy's are called "Quantum" so there is that too.Like most Bond movies, it was the title of one of Ian Fleming's 007 stories. _URL_0_ The film, however, has little to do with the original short story plot-wise.> A quantum is the amount of energy it takes to get an electron from one shell to another, right? [This is what dictionaries are for].
What is actually happening to metal in a microwave?
As microwaves hit the metal, electrons build up on the surface. Depending on the shape of the metal, this may result in an electric potential which eventually arcs, creating a spark. This spark can be enough to ignite paper, starting a fire in the oven.
How does facebook avoid paying its fair share in tax
I'm not going to talk specifically about Facebook or Ireland but this is how profit shifting usually works. Country A has 30% company tax and 300 million people and all sorts of publicly funded programs to create a huge Internet market, including skilled staff. Country B has 1% tax and sweet fuck all in population, no publicly funded innovation and no skilled staff. Internet Co sets up in Country A because that's where the market is and the skills are. Internet Co does well and is worth billions raking in $30 billion in revenue with $10 billion in profit before tax. Internet Co doesn't like paying $3 billion in tax . Internet Co sets up a new company in Country B called Internet B Co. It makes it the head company and assigns all IP rights to the name "Internet Co" to Internet B Co. Internet Co still operates in Country A because that's where all the skills are etc. New Internet B Co charges Internet Co $10 billion in IP licence fees to use the name. All of a sudden Internet Co makes zero profit and pays zero income tax to Country A. All of a sudden Internet B Co is making $10 billion profit . But Internet B Co is in Country B where tax is only 1% which is only $100 million tax. Internet Co Group companies has lowered its tax by $9.9 billion. CEO and CFO get $100 million bonus. Country B gets a $100 million tax windfall by doing sweet fuck all other than having low tax.
How do scientist determine how many animals are left of a certain endangered species?
Depends on the species. For larger animals like elephants you can do aerial surveys to count the number of family groups. Mammals are also very easy to keep track of via radio collar or transmitter. For harder and more elusive species all we can really do is calculate habitat area, calculate how much area is needed for an individual and if that area is cut down then the individuals are out of habitat. Keeping an accurate estimate of population sizes requires a knowledge of the animal involved, which is why studies relating to population dynamics of a species are actually really important to conservation.
What is Blu Ray? Why is it significant?
It's essentially the same tech as a cd or a dvd, but it uses a laser which is in the blue spectrum rather than the red spectrum, which means it has a wavelength that is considerably shorter than that of the previous formats and allows you to write the data closer together on the disk, which means you can get far greater data density.
Can we help who we are aroused by?
There's many possible meanings of this question. If you're talking about homosexuality then no, you can't, but do mean things like sexual fetishes or sexual disorders like pedophilia? Most fetishes develop over time and are not considered harmful, so people don't usually try to change. Pedophilia, however, can be treated with various therapies like aversion therapy. Aversion therapy teaches you to associate something pleasurable with something very unpleasurable. It happens naturally, like when you eat something that makes you sick, you don't ever want to eat that again. With pedophilia you can teach people to associate their sexual desires with extremely disgusting visualizations. Or you just be talking about preferences, like ass vs boobies, for example. Then yeah, those evolve over time.Not in the heat of the moment, usually, but over time you can. Exposure to different circles of people can change who you get attracted to. Cutting out media messaging about what to find attractive can also definitely have an effect.
Why do cities in China still have such high pollution when they have so many bike users?
Most Chinese pollution is particulate based. Mainly from the burning of coal . Chinese emission regulations are actually stricter than in the US from a design perspective however they seem to be much, much more lenient / not enforced when in operation. In the West however pollution is more chemical based such as NOx and SOx from vehicles.Manufacturing/production/factories/commercial use WAYYYYY outpace your average joe when it comes to generating pollution. China has a ton of that, and for a long time was not up on environment requirements for them either. They're starting to change their tune on it though.
How do giant cruise ships float?
The mass of the volume of water that they displace while sitting in the water, is greater than their mass. So, even though it's an enormous pile of metal, it's still "lighter" than the water it's displacingThe metal is heavy, but there is a lot of air inside the metal structure of a cruise ship, and the air is light. Together the metal plus air is lighter than the water, so the cruise ship floats. If you put a hole in the metal so that the water could rush in and push the air out, the cruise ship would sink like the "Titanic" as the metal plus water would be heavier than the water.
Being caught for piracy.
For direct downloads from a server, they have to either seize the logs of the server, or work with ISPs or other men in the middle to figure out who is downloading what. For bittorrent and similar peer to peer systems, it's pretty trivial. Find a torrent you want to monitor, join the downloaders, log the IPs of the peers. There is dedicated software for this and companies which do this for film studios/distributors, lawyers etc. Once you have the IPs, subpoena the ISPs owning the IPs to reveal who the person at that end is. Then take that person to court. As to how they decide who to go after, no idea. I guess it's a mix of going after the biggest infringers, "setting examples" and doing what's directly profitable Isn't it mainly the "uploaders" that they go after?
Is there a reason why "hold music" when you call businesses has to be so obnoxious?
The quality of phone calls have to be able to transmit voices acceptably. Music requires much, much more data and so no matter what music you put on there is going to sound like shit. Music that is very "full" and uses a large range of frequencies at once will sound even worse. Very simply solo piano or something can be OK.
How would a compete collapse of Russia's economy affect the rest of the world? Which countries would suffer the most?
With my basic understanding of economies and greater knowledge of energy markets, Russia's current troubles won't have too much of an effect on the rest of the world. Most of their money comes from energy exports and with their issues in Ukraine earlier this year, many of their customers had already turned to other sources. Russia, unless the price of oil goes up soon, will be forced to pull of Ukraine and get the restrictions lifted as they are in a free fall. Putin being who he is, I don't see this happening so I think that Russia will be the country that suffers the most with most other countries feeling a slight effect but not much.
Beastie Boys "No Sleep Till Brooklyn" on TNMT movie commercial? Despite statement that no song will be used for commercials??
Sabotage was in Star Trek . I think that films are OK with the Beasties, including commercials for the movies. I think the no commercial clause was actually worded as not used to sell commercial products, like Coke Zero or Tampax. That cheapens the music. Film is another form of art, that they probably respected. To be a part of that, they likely feel honored by" His wife, Dechen Yauch, has been granted permission to manage and/or sell all of Yauch’s artistic property." guessing she sold that one songIs this TMNT a sequel to the last one? Or are they remaking it again?"No Sleep till Brooklyn" was used in a handful of films before Yauch died, so that may have complicated things enough that the clause is only valid for songs that haven't already been licensed.
how are movies that were recorded in a lower definition able to be released in higher definitions?
They were recorded on film, which isn't limited to an amount of pixels- for the most part. Remember that they were broadcast on a huge screen. As long as you can get the original print you can re-release the movie as HD.There is a lot of confusion here because "high definition" is a *television* standard, and movies are mostly on film. And as technology has progressed, we 've been able to make television transmissions higher and higher definition. That said: a movie camera 60 years ago produced a higher resolution product than any television you can buy today. Film has *very* high resolutionThere are two reasons. One is that most movies are recorded on higher definition then they are released on. A lot of movies are recorded on film which have very high resolution. Even those scenes that are not as high resolution are still higher then the VHS and DVD releases because the movies use higher resolution film and the editing process might also reduce quality of the picture. Secondly a lot of the HD releases get a pass of post processing to artificially sharpen the picture and improve effects that could be done better with modern technology and higher standards for quality. Technicians will usually go through the movie frame by frame and add details and texture to make it look better. Sometimes entire scenes are redone if possible.I'll try to give a simpler answer. They weren't recorded in low definition, they were actually recorded in hi-defintion, they were just transferred to a low definition format because old televions and vhs technology had low resolution. So they just go back and re-transfer those movies to high definition for modern tvs and blu ray players.
Why do some electronics have lights to indicate that they are off?
Electronics don't have lights to indicate they're off. If they are off then by definition there's no power to run the lights. However, some electronics *do* have lights to tell you they're on standby or low power mode. This is important because you need to know whether certain devices are still powered to ensure they can function. For example, your DVR needs to be on standby/low power so it can still boot up to record your shows.
Why does it seem that more men snore than women?
It may just be the case that it's louder when men snore because men as a rule have larger lung capacities than women.If it seems that way, its either personal experience or media portrayal, neither of which accurately reflect the actual worldThe truth is snores just as much as but hears about it more because likes to make a big deal out of it. Edit: looks like some five year olds cannot handle the truth. Nobody here deserves downvotesWomen complain more. Men are just happy to have someone in their bed.
How is powerful acid stored without eating away its container?
Highly inert materials are used. Frequently glass or a dense polymer. "powerful acid" simply describes a highly reactive solution that reacts in a certain manner. You simply have to pick a material that resists the particular chemical reaction the solution favors.
If some letters are silent in certain words then why include then at all?
Often just tradition. When they began printing books in English, there weren't many typesetters in England, so they imported Dutch typesetters who often spelled English words in a Dutch way. So that's how we got the 'h' in 'ghost' and 'ghastly.' Other times the silent letter actually serves a purpose. The difference between 'can' and 'cane' is the silent letter 'e.' That 'e' lets the reader know that they should pronounce the 'a' as a long vowel. Edit: [A much more eloquent source]
Why do historians talk about civilizations being more advanced who had "the concept of zero," and why was that concept so hard to develop?
Creating a "concept of zero" is the first step towards using math for something more complicated than counting cows in a herd, or a weight in gold. Once you are at that point, it's possible to move on to more complicated math, which leads to basic engineering and architecture. Zero is the first mental jump from "numbers are good for counting things," to "we can use numbers to build things so that they won't fall down!"', "So, clearly all peoples had a concept of not having anything of something. If you have three sheep, and sell three sheep, you have no sheep. But what we're talking about is the concept of zero in mathematics. In basic math, there's little point in it -- you're not going to bother to add the number of your zero sheep to anything else. You'd just skip the sheep because you don't have any. But the concept of zero as a distinct number, like 1 or 5 or 20, is important for more advanced mathematics. A civilization that hadn't grasped the concept of zero isn't going to be able to develop other concepts like negative numbers and other higher math. This lack of advanced math would limit the how far science and engineering could progress.
Why did older CRT monitors for computers typically work in a black background with green text?
[Green P1 phosphors ] had long persistence . Amber P3 was medium persistence. White P4 was faster. Longer persistence meant your video could be at a lower frame rate without flicker. Nobody was watching videos or playing fast games, so it didn't really matter.
Google made 3bn USD profit, but wall street is not happy, eli5 me why??
Because they expected more. Like you're 5: imagine I promise you 20 sweets next week. But when next week comes around, I only have 15 sweets to give you. You wouldn't be happy, right? But that doesn't fully explain it. Imagine I promise you 20 sweets next week if you give me your pocket money. But Johnny's dad says that if you give *him* your pocket money, you can have 18 sweets next week. Of course you give your pocket money to me. But now, when I give you only 15 sweets, you're *really* mad, because if you'd known that you'd only get 15 sweets from me, you'd have given your money to Johnny's dad and not to me!
Difference between 'fiscal' and 'financial'
To put it in simple terms fiscal just has to do with government spending & revenue. You may hear or read the term \'fiscally conservative\' which is the view on how the government should spend their money, which generally means reducing the government spending and basically reducing the national debt. Fiscal conservatives believe in limited government spending, free market, & less min. wage. To be fiscally liberal is the belief that government intervention is the best way to bring economic equality & stability, & to be in favor of a progressive income tax to just name a few. You should definitely watch gubernatorial or presidential debates between Democrats & Republicans and you should observe on their economic & social policies they believe in. \'Financial\' is more of a broad term that can be applied to a single person or a corporation. "He is financially responsible". "Sony is financially a stronger corporation"
Why do busses not have enough seatbelts?
Busses have a very large mass compared to anything they hit. In almost every collision a bus is involved in, it does not decelerate quickly enough to do serious harm to the passengers. Large mass means a lot of momentum and most things that get hit by busses just move out of the wayTypically they say it is for safety, if the bus catches on fire or crashes it would be hard to get all of those people out of a seatbelt and to safety. Edit: Especially a young child who may or may not be able to properly work a seatbelt.
Data limits. Why were pioneer plans offering unlimited data and now we're seeing caps on not only cell service, but even at-home ISPs?
ISPs can no longer increase revenue by adding subscribers. Nearly everyone that wants and can afford broadband already has it. This leaves them looking for new revenue streams. It is also a way to limit cord cutting.
Why do some people never get sick with colds or flu when everyone else does?
As a non-expert, I would assume it's due to two primary factors. 1) Genetics 2) Prior exposure in a small amount to an illness that allowed the body to build up an immunity. I have no medical proof to back it up, but the people I know who are sick most often are the ones continuously using hand sanitizer. I believe it's because they never expose themselves to small amounts of viruses. Then again we could get into that whole correlation vs. causation thing. Perhaps they started using sanitizer because they got sick all the time?
If I pour one cup (~600) of bees into the dryer and run it (without heat) for a couple minutes, could they just fly around in the middle without issue?
There's only one way to find out. Be sure to take a video, you're going to need it for the TIFU.Where would you get a cup of bees? Even if you had this cup of bees, how would you pour it into the dryer?Probably not Even though the air in the middle wont completely rotate with the dryer, most driers have fins and would generate a lot of turbulence. That would make flying a challenge, and any bee that drifted out to the sides would get beat up on by the fins. But it would depend on a lot of things - size of the dryer, how fast it spins, etc.Oddly specific question. I don't believe they could due to the dryer fins causing some kind of vortex in the confined space of a dryer.The bees would quickly get fed up with trying to fly. However, not every surface is moving. They would all just congregate on the dryer door and be fine. You may not even get a PETA call. Disappointing right?
Why exactly wasn't Netflix offered to those 130 countries before today?
Varying laws and rights holders is the intuitive answer, but if you think about it, that doesn't explain why the 130 countries were added at the same time as opposed to gradually as Netflix worked through legal issues. The truth is it's a numbers game. A common clause in media rights contracts limits the number of countries a given media may be sold to *as a function of the decade*. This practice was instituted after World War II, when it became apparent that the number of nations will very rarely shrink , and more often grow, leading to an upward trend in the number of nations. The idea is that the contract will maintain a roughly consistent share of the global market, reducing the rate at which it devalues over time. Since the practice became common in 1946, it is customary for such contracts to begin the decade on January 1 of each year ending in 6.
Why do episodes of TV shows air months apart in different countries even though they still air in the same language?
I'm pretty sure this has to do with licensing & intellectual property laws and getting them sorted out globally.
If wood pallets are in such demand, why are stores giving them away?
There are two types of wood pallet: hardwood and softwood. The hardwood ones are in true demand, and are reusable. These are generally painted. The softwood ones are, for the most part, considered disposable and those are the ones you will find for free. Be careful where you get your pallets. Many are loaded with various chemicals or bacteria that could potentially harm you.They are sold, you can buy them in many places, from Home Depot to ULine. They generally are not free. Sometimes, there is a refundable deposit involved. Sometimes, it's simply included in the shipping and handling cost . You paid for it, just indirectly. The company I work for gets 2-8 pallets per week of freight deliveries, with the cost rolled into shipping/handling. We use them if we need to, but generally, just throw them out and someone dumpster dives for them. I'd reckon many of the free ones floating around were found the same way.the store i work at sells them for $5 each. they arent free in alot of places because the shipping company will give a $5 deposit back on each pallet
