The causes of the recent stock market crash in China and the effects of it on the Global market
We believe that China's growth since last 10 years was mostly from construction and manufacturing sector. People leverage/take debts to spend now for future returns. These debts are huge and inflating the economy right now, and pushing the prices in stock market currently to reflect the future earnings. However, recent...
Why can I suddenly smell items from across the room when I notice the items visually, even if I couldn't smell them beforehand?
Reticular activation - we tend to notice phenomenon we're aware of. Its why when you buy a car you never heard of, after you take it off the lot, you start seeing it everywhere.
On Planet Earth they talk about how Marine Iguanas can hold their breath for 30 minutes underwater, how are they feeding if they are holding their breath ?
> Are they able to close off their airways while they eat or do they have a separate process ? They close off their airway while they eat, much like how humans close our airway when we swallow. Get a cup of water, hold your breath, and take a drink while holding your breath. This is something you can do perfectly well ...
Why does the iris have color?
So you aren't asking how but "why" correct? This question would best be answered by looking at an iris with ocular albinism. When the body has significantly reduced amounts of melanin then most everything will be pale. Grey to pale blue irises, white hair, pale skin. This person won't function well in bright light and ...
Why do I tend to start disassociating a word with its meaning the more I look at it? Like, "cat." Cat, cat, cat.
If your brain is receiving the same information for a while, it starts to ignore it so you can focus on other things. It's like how you forget about a smell if you're around it for a while. The same thing happens with words and their meaning.
I continue hearing about the idea of term limits in the US Congress. What would be the process of getting term limits set up, and who would have the power to do so?
It would likely require an amendment to the US Constitution in the same way when the 22nd amendment to the US Constitution limited the presidency to two terms. Article V of the Constitution lays out what's required to add an amendment: "The Congress, whenever two thirds of both Houses shall deem it necessary, shall pro...
Why is it important to brush your teeth in the morning?
Plaque build up on your teeth. The conditions when you are sleeping, such as a relatively dry mouth, can help them build up even better than they do when you are awake. These teeth, when exposed to some foods, make acidic products which can weaken and even permanently damage your teeth by removing the material that mak...
What the heck causes that searing pain when a person bites down on aluminum foil? Does it happen to everyone or only people with fillings? How about just a cavity but no filling?
Dental Student here: The phenomenon you have noticed is called "Galvanic Pain." Basically an electrochemical circuit is formed when metal restorations come into contact with a dissimilar metal alloy in the presence of saliva . This is especially painful because restorations are so close to the dental pulp . Pain can al...
How were dinosaurs so gigantic?
They had hollow bones. They had a much more oxygen rich atmosphere. That kind of size is no longer advantageous. They evolved into birds. Bird form was more advantages going forward. Reptiles could one day evolve to be much larger again. But right now it serves no point.Yeah the main point is that there was more oxygen...
"subsidy: The banks that are potentially the most dangerous can borrow at lower rates, because creditors perceive them as too big to fail."
If I'm a creditor and a someone wants to borrow money from me I'm going to adjust my rates based on how likely I am to get my money back. The more likely I am to get paid back, the more likely I am to charge less interest since I know the payments will be coming in as scheduled and I can plan my other finances around t...
How is it that the nervous systems of biological organisms are generally more efficient at processing information than human made computers?
Because we are made of nanotechnology, and nanotechnology is relatively energy inexpensive to run. After all, you're only performing actions on specific molecules rather than moving millions and billions of electrons.The human brain is much more complex than any man-made machine. More parts, and more connections betwee...
why my dad can't tell me anything about his jury duty case but they televise ones like the Jodi Arias case
Because he swore to keep it quiet. The judge could have allowed the media to be more involved and informed of the case your dad is a juror on but it isn't necessary. The judge allowed it in the Jodi Arias case though, but the jury still was restricted in a lot of ways just like your dad.
Why does it smell like chlorine when you cry?
You should probably get that checked by a doctor .Chlorine is iratent. It is much like sulphur dioxide the onion smell. I used to work with a 12.5% concentration working at a food plant. I will try to find a link to a MSDS sheet. The point is it kills cells bacterial or your own. Your eyes, nose, throat, and lungs are ...
Why does Japanese and Chinese media seem to portray the Buddha as some sort of dogmatic deity, when the crux of his teachings were that he's just a guy.
Buddhism spread from India to China, Korea, Japan, Southeast Asia over a period of centuries and although all schools of Buddhism trace their origin to the historical Buddha the Buddhist traditions throughout Asia differ in their specific "theology". The most popular forms of Buddhism in China, Korea, and Japan hold to...
Why do dogs like the game of fetch with a twig or a ball soo much?
Dogs have historically been used for various tasks The act of fetching alone is one that has been driven into them for many generations, so yes, it has a genetic component. But also their brains have evolved to be very task-oriented. One of the truest things I've read/witnessed about dogs is that a dog that's doing som...
how they put up a tower crane
[Consider this image] I may miss a step here but the jist of it is this. The grey portion is the tower heading down to the building. When the crane is first put on the building there is only one grey section. When you want to raise the crane one unit of grey section you detach the red one from the grey one, then use pi...
Why is golf always associated with “Rich people”
Because it's an expensive sport to play. The play area takes huge areas of land to maintain, which requires a lot of money from the operator, which requires a lot of money from the clientele.The more expensive the equipment the richer the players before turning pro. Use of fields is part of the equipment. This is why s...
Why does darkness make you see "things?"
Darkness is an empty canvas to the eye. It gives the imagination and your brain's visual processing centres free rein to be creative. The [white noise image] seen on tv's offers the same effect.
where does 'grounded' electricity go to once it's in the earth?
Well, first off, household power is AC, so charge never really goes *anywhere*. It just jiggles back and forth in the wire. Anyway The same amount of charge is drawn out from the Earth as is put back in. Electricity doesn't work by pumping extra charge into something. Rather, there is charge *already present*, and elec...
Why are the sanctions against Russia so specific? Why not send a stronger message with wider sanctions?
Ukraine is not part of NATO, nor is it traditionally part of NATO's sphere of influence. It is traditionally part of Russia's sphere of influence. If major economic sanctions were imposed, Russia would see that as disproportionate, because Ukraine is not supposed to be of any interest to NATO. So Russia would retaliate...
Why does fanning your face when you're hot seem to cool off your entire body?
Lots of blood flows to your head, so your head is a really important place for expelling excess heat from your body.
Why does Turkey have to wait until May 2018 for the release of Straight Outta Compton?
So movie studios will sell the rights to their movies off to local companies. This could be because they don't have the infrastructure in that country to distribute the film or they don't want to take the risk. When they sell the distribution rights, that company may feel it is better to wait on running the movie for f...
The difference between a gasoline engine and a diesel engine.
Both engines convert fuel into energy through combustion. The difference is how the combustion happens. In a gasoline engine, air gets mixed into the fuel, the mixture is compressed, and then the mixture is ignited by a spark plug. For a diesel engine, there is no mixing and the air is compressed first. The air heats u...
Why are illegal immigrants bad for America?
If immigrants from poor countries come into your country and perform jobs, they will most likely send the money home to support their families. That money is sent *out* of the economy of the country and is not recycled back in. So most of the salary of that employee flows out instead of jumping from citizen to citizen ...
Why does my arm hurt all day if it hung over the edge of the bed when I slept?
this has happened to me and i think it's because the muscles and/or joints were stressed for a long period of time. Not badly enough to wake you up out of a sound sleep but bad enough to feel it the next day.
what are these "knots" people speak of when getting/giving back massages? What are knots, how are they formed and how do they disappear?
I actually asked that one a while ago. The ELI5 would be: Our muscle can tense up when we perform activities, or when we are stressed. When our muscle tense up, it forms a "knot". Our muscle does not know how to relax itself after tensing up. These "knots" are essentially tensed muscles, which causes a person to feel s...
How do two way mirrors work?
The sad truth is that you've been lied to! One-way mirrors are not, in fact, one way mirrors. They're just partially silvered glass; this makes the glass reflect more light than normal glass. Then, you have one side of the glass be in a bright room, and one in a dark room. When you're in the light room, most of the lig...
Why after shaving do I get pimples?
Small nicks or cuts on your skin get infected. Hairs once cut smooth to the skin have a chance of becoming ingrown and infected. And you can sometimes push dirt and bacteria into a pore causing it to become infectedRazor bumps are ingrown hairs. Either you shaved too close, and the hair is growing beneath the skin ; or...
Why do dogs love to stick theirs head out a car window, but hate it when you blow on their faces?
Blowing in a dogs face is a sign of dominance source: I worked in an animal hospital for a few yearsI got the answer directly from the source. My dog says the reason is because woof woof woof woof woof woof. Fascinating.Sidenote: Letting dogs ride with their heads out of windows can cause long-term damage to their eyes...
Why is Imgur so much faster is loading gifs than Minus is?
I don't know what Minus is, so I'm assuming it's a significantly smaller image host. The infrastructure behind imgur is likely significantly more advanced, with more powerful hardware. As a result, it is able to process requests more quickly.
Why are the offspring of some animals so different to their adult form? (e.g. tadpole/frog; caterpillar/butterfly)
It allows the different life stages of the animal to take advantage of different conditions and food sources. In some cases the larva should really be looked at as the "main" organism and adults only as mating/dispersal mechanisms; some adult insects do not even eat , and they only live for short period to fly, mate, a...
EPLI5: the situation in London
I'm a Londoner who just woke up about five minutes ago and had no idea anything *was* happening in London. So, uh thanks for the heads up. Edit: Oh, and from what I can gather, people are angry that police shot dead somebody called Mark Duggan, [though I can't find very many details on what he is supposed to have done,...
Why do balloons hold/attract so much static?
Rubber is an insulated material. That means charges cannot move like they can in metal . Because charges can't move, when they are transferred from other materials, they build up due to rubber's poor conductance. The build-up of charge leads to the static, because it's built up to the point where it can't hold any more...
What is ventricular tachycardia and how dangerous is it?
SVT, or *supraventricular tachycardia,* is a condition where the two upper chambers of the heart sometimes beat too fast for the ventricles to keep up, and this means there's less fresh, oxygenated blood moving through the heart and around the body. Ventricular tachycardia is similar, but it involves the *ventricles*, ...
Why does it seem like airplanes move super slow while on one despite them actually going approx. 885km/hr?
It's about the distance. They're usually very far away from you. Let's say a place flies at its usual 10km altitude, and you look at it at a 10° angle, then it'll be over 56km away from you on the ground. Because of this huge distance, you only need to move your head/eyes a tiny bit, which gives the impression it's slo...
Why are us street numbers so random?
Many places in the US houses are numbered by the cross street, so between 6th and 7th avenue the houses go from 600 to 700. So if you're going to use this system it makes a certain amount of sense to space the numbering out so that 650 is in the middle of the block. Armed with an address I can reason out the best way t...
Net carbs, fiber, soluble fiber, sugar alcohols
There is a very active subreddit for this topic; /r/keto Jist: It's about what affects your blood sugar. Any types of fiber do not affect your blood sugar, so subtract them from the total carbs. Sugar alcohols are more complex; there are a ton of different ones. Some have 0 effect on your blood sugar, others have a mod...
If a person is shot in the heart do they die instantly or does the brain live on for a bit?
their whole body lives on for a little while, even the heart. It takes a while for the cells to dieThey will live for few minutes until the cells die from lack of oxygen
Hematuria caused by UTIs, how does this work?
Kidneys filter blood, if they are not working properly due to infection you'll see blood in urine. Also if your UTI is due to bladder stones or kidney stone they are possibly causing the hematuria. A urologist would best answer your question.Bacteria irritate tissues and cause inflammation. Part of the inflammation res...
How do I find out what politicians really stand for?
Voting record! All Congressional votes are public, so you can see what he voted for or against in the past. Are there any bills you feel strongly about? Look them up!
how does my iPhone know to send an iMessage to a contact that previously had an android phone?
Your friend's iPhone has registered itself on Apple's iMessage servers. Your phone, as soon as you type his number into the To box will ask the iMessage servers if they recognise him phone number. If they do, the message goes as an iMessage, otherwise it goes as a text message. You can see the point where this happens....
Why does your perception of a first-person video seem so unnatural when you live your entire life seeing in the first-person?
When your eyes are about to move, a signal is sent to your brain letting it know "this sudden change in frame of reference is me moving, not the world". Carefully poke your eyeball from the side--when your eye isn't sending this message--and your vision will jostle around like a video. You can't track everything becaus...
When electronics, such as smartphones, preform multiple tasks at once, or for an extended period of time, what makes the device hot?
Any time an electric current passes through a conductor, a little bit of heat is generated. If an electronic device is hard at work, you have lots and lots and lots of tiny currents passing through lots and lots and lots of tiny conductors. Together those tiny amounts of heat add up to a substantial amount I really. Th...
Why can you not recall a memory or phrase at some point, that you can recall at a later point?
I am by no means a scientist and my guesses are often wrong. However i will poke at this one. My thinking is that neurons may be overloaded with other garbage and the thing you are trying to remember is stored away on a path that is unreachable due to the volume of traffic. I am interested on hearing an answer from som...
Why did a leap second break the internet?
The leap second itself didn't do anything. It's that some computers had the leap second implemented while others hadn't, so the time stamps in the packages made the one computer think "wow, these packets are really old" and so it sped them up, and started transmitting faster, but then those other systems were like "shi...
Is an electric shock safer to withstand while wearing shoes, standing on solid ground - or safer if standing knee deep in the water/river?
The former is better if we are talking about limiting the current going to ground through you in a situation like touching a live wire with only one hand. If you are actually well insulated from ground no current will flow and you won't get shocked; lineman servicing power lines can touch wires at many kV because they ...
Why are there no supersonic commercial airliners?
The Concorde couldn't really be described as a commercial success. In order to achieve supersonic speeds, it had to compromise with a smaller body that could carry few passengers. It also used more fuel than other passenger planes and was more expensive to maintain. Airlines would have to charge ridiculous prices to ke...
How does charcoal work? Doesn't burning wood the 1st time defeat the purpose of reusing it as fuel?
When you make charcoal, the heat splits off molecules from the wood which contain mostly carbon and hydrogen atoms. These contain a lot of energy, but they need a lot of oxygen to burn completely, which results in a rather low temperature and smoke. What remains is relatively pure carbon, which burns much hotter, and w...
What is intrinsic value(ethics)?
The term "intrinsic value" as used by most formal ethicists refers to the value assigned to a thing by virtue of its inherent qualities. By contrast, the extrinsic value of a thing would be the value attributed to it by virtue of its usefulness in some context. So, for example, arguably a dollar bill has little intrins...
The controversy over the Cubs sending Kris Bryant to the minors
Kris Bryant is a Cubs rookie who played **REALLY** well in Spring Training, batting .425 with 9 home runs in 40 at bats. Because he's a rookie, he can't become a free agent until after the 2020 season. However, if he's not on the Cubs roster within the first 12 days of the season, he wouldn't be able to become a free a...
Why do majority doctors have such a bad hand writing?
I asked the same question during my pharmacist studies and the teacher basicly said: They have spent dozens of years studying, having to write down whatever the lecturer was saying. They had to adapt and write extremely fast with low detail in their letters thus creating some kind of writing that looks like arabic to t...
Why do autonomous cars made by most manufacturers look so goofy with sensors on the roof but Tesla cars look so normal?
I think you're correct. That, and When you're designing a production one from the ground up, you can build in all the features rather than having to modify an existing model.
If all materials, even non - conductors are diamagnetic, then from where do they get the electrical current to produce an opposing magnetic field?
It isn't true that all materials are diamagnetic . Most materials are paramagnetic . A minority are ferromagnetic . And chromium alone is antiferromagnetic .
The Fedora? Why the hype on Reddit?
The fedora is considered a trademark of a certain type of person. I don't think said type has a name, and is usually just referred to as "fedora" or simply "neckbeard". As usual with internet definitions, they tend to be quite vague, but here are some traits commonly attributed to Fedoras: - fat, neckbeard, some type o...
Why is it easier to remember images/pictures as compared to textual words?
It's not for me. People learn differently. I see words in my head. I often forget people's faces.When you see an image of an object you are more likely to recall it than if you saw it as a word. [reference] . This is caused by dual coding. When the brain sees a picture it activates the verbal and visual memory systems....
What causes a "gut feeling?"
There is a part of your brain called the OrbitoFrontal Cortex that basically makes your decisions, subconsciously for you, before you even realize it. It bases this largely on emotion and past experiences, or whatever close approximations it can find buried in your brain . It does this subconsciously and does it faster...
Why identity of the winner isn't protected when they win a big lottery?
I just looked this up yesterday. If the winner is anonymous then the public has no way to prove there was an actual winner and it wasn't rigged. 6 states allow anonymity in the USA though. I believe there were also some instances of it being rigged in some states so their concern isn't completely unwarranted
How come we have no memory of being a newborn?
My understanding with it has to do with how rapidly the brain is developing during the first few years. The brain does the largest amount of growth those first years and you are learning pretty much everything. So your brain is dedicated to learning and building synpases. So pretty much your brain is too busy learning ...
What is a mutual fund? How is it different from a company offering stocks?
Buying a stock or shares in a company is where you directly own the shares in your own name and can either chose to pay for advice from a stock broker or trade in the shares yourself.A mutual fund is where you and many other people and institutions pay money to a fund and in return receive units in that fund. Fund Mana...
How are expiration dates so precisely determined?
I would guess it was packaged at 08:54 on the day it was packaged. So say they know it's guaranteed good for a month. Then it was packaged a month ago, it was at July 5, 08:54.I don't know but I hope it has something to do with time-traveling spoiled food verifiers. "Sir, that juice spoiled at exactly Aug 5 at 8:54. Ma...
if the lawsuit against Obama proceeds, what court is it heard under? How does this work?
It probably doesn't get heard in any court. There is a requirement in the federal judiciary that the aggrieved party can show harm was done to him . Keep in mind that matters of "unconstitutional behavior" are part of the impeachment process, and cannot be pursued in any court. The impeachment process is completely in ...
Why sometimes we don't understand what we read no matter how many times we try.
It could be caused by a couple of things: We all learn differently but typically encode things into memory in a similar way. Some individuals are visual learners and can memorize or learn by observation alone. Others need a physical connection wherein they learn by doing; their brain is encoding and saving the informat...
How can there be flowing water on mars when the temperature is so low?
1) The temperature ranges from -80° F to 70° F. 2) The salts dissolved in it reduce the freezing point so it stays liquid at lower temps.Atmospheric pressure, brine salt water has a lower freezing point, surface of Mars isn't always below the freezing point.
given a worldwide consensus, how would one go about dropping or propelling the earth into the sun?
Fire an astronomical amount of rockets in the direction opposite to the Earth's motion. The best time to do this is when the Earth is farthest away from the Sun. Basically, the goal is to just slow the Earth down and let gravity do most of the work. The only reason we stay in orbit is that the Earth is moving fast enou...
What does it mean for a file to be corrupted in a computer?
The data is unreadable. The equivalent for writing on paper is that either the ink got smudged or that there were too many typos while transcribing it. Either way, your computer can't understand what it's trying to say.Have you ever started typing, had your fingers on the wrong keys, and just wound up with dp,r dpty pg...
How do we reattach limbs/extremities
Basically, you stitch everything back together under magnification. The order in which it's done may vary, but the idea is that you fix the bones together to give you stability, then you use a microscope to reconnect the blood vessels so that the limb doesn't die, after that you suture the nerves so that sensibility ca...
Why does coffee smell so good but taste completely different?
It comes down to many things, part of the explanation is that our sense of smell can only determine the molecules that become airborne, while drinking the coffee will mix the sensation with also affecting the taste buds, where coffee has a very tangy and stringy taste. Another part of the explanation is that the smell ...
Why are we not allowed to use cellphones during certain times during a flight?
Not a complete answer, but : there’s an episode of Mythbusters you can probably see on YouTube about this
Why do most unknown calls I receive on my home phone end up having no one on the other end?
They're usually from call centres where they have a machine automatically call numbers on a pre-assigned list. Then, when a voice is detected on your end, someone is connected on their end to talk to you. It saves them time, even if it does result it people going "Huh. No one there" and hanging up before they get a cha...
what made the Disney movies of the 90s so good?
I mean, it's probably nostalgia for the most part— but also, production wise, Disney was really hitting their stride and finding the tone they wanted to take with their movies. If you think about it, earlier Disney movies were kind of creepy, or sad— they were still trying to find out what chord they wanted to strike w...
What makes things bounce? Why are some things bouncier than others?
Bouncing is about storing energy. When a ball falls, it gains _kinetic_ energy, energy as movement. When it strikes a hard surface, that energy is used to deform the ball - we say it does work on the ball. As the ball is _elastic_, it returns to its original shape, pushing on the hard surface, pushing the ball back int...
what the hell is going on in /r/Gaming?
/r/pcmasterrace got banned because some users posted personal information on a /r/Gaming mod who had apparently 'dissed' PC gaming due to some pictures of that 'Large Pixel Collider'. Posts related to PC gaming were removed, angry things were said, and the mod was doxxed, apparently by users from /r/pcmasterrace. There...
Why does it feel even more euphoric to stretch when you have a cold or the flu?
Well I tell you what-not because of the blessing of some phony god! But actually, you are likely down a lot when you are sick, moving less, and your muscles aren't used, they need to be stretched and used, and so your body rewards this. Think about it, when you're sick, youre probably not gonna make the decision to go ...
Why do phones batteries drain so fast in the cold?
I'll modify the prior response: A battery produces power through a chemical reaction. When the temperature is colder, it's harder to create that reaction, so your phone must have a higher amount of voltage in the battery to sustain the same battery percentage. To use car batteries as an example A typical car battery ha...
Why are old people so bad at technology?
_URL_1_ How good are you at fixing a car? A lot of older people can and did do that. How good are you at driving a mule team? A lot of older people did that. How good are you at cooking a full meal from scratch ? A lot of older people, especially women did and do that every day. Plus once you get to a certain age, you ...
Why do I enjoy small amounts of pain, especially from poking at my gums or biting my inner mouth areas?
Endorphins are released every time we are injured. Endorphins act as natural painkillers similar to morphine. This is evolutionarily advantageous because when we get injured, we don't want to be wallowing in pain in a situation where we may get even more injuries. The endorphins allow us to temporarily ignore the pain ...
How do sites like _URL_0_ make money?
They are running at a lost in exchange to create a larger player base so when they do integrate ads they will have a pool of audience ready to see those ads which results in profit. They also want to attract players who would pay for skins and etc. when implemented. Also this game is found on _URL_0_ so this game could...
Why do some stores have a minimum charge for credit card use?
Stores need to pay credit card companies a fee every time they take a payment via credit card. That's how credit card companies make money. With small transactions, the fixed part of the transaction fee is high relative to the size of the purchase - high enough that it can actually cause businesses to lose money on sma...
Why does pouring warm soda into a glass with ice cubes create so much foam and fizz?
I believe its nucleation. The rough surface of the ice provides a huge surface area for bubbles to form on. The warm soda melts the outer edge of the ice, leaving it smooth and rapidly reducing the area for nucleation. So the fizz subsides fairly quickly.
Retirement/ old age pension.
I'd always recommend saving some extra money, no matter where you are in the world. Don't trust other people for your retirement.
why does the sky feel bigger the closer you get to equator?
This is an odd question, the angle you can view of the sky is actually smallest at the equator and largest at the poles. However, because of the temperature, clouds are frequently higher in warmer climates, so maybe the clouds being higher makes you feel like the sky is larger?
You can lose the senses of sight, hearing, taste and smell. But can you lose the sense of touch? Also, can you born without it?
I think losing the sense of touch would usually be in the case of nervous system issues. That usually result in paralysis too. People who are paralyzed usually don't have any sense of touch in the affected areas either. Then there are a few cases where people function normally, but have no pain receptors. Apparently th...
The difference between 32 bit and 64 bit computer programs.
So the difference is really hardware, and a 64 bit program is one that is made to run on a 64 bit CPU. Think of the CPUs as having doors that stuff can go through The 32 bit CPU has 32 doors, the 64 bit, 64. So that's why software written for a 32 bit processor can run on a 64 bit processor, some of the "doors" are jus...
Why are blood types even a thing?
I think you 've answered your own question. Evolutionarily, blood transfusions are not "a thing", so blood being compatible between people is not something that can have been selected for.You just stumbled onto a question that science hasn't quite solved yet. I'll give you a link to [this article] that explores your qu...
What are the different chapters of bankruptcy?
The chapters are from [Title 11 of the US Code] . A few of its chapters are no more, and a few others are general legal stuff. The rest define specific procedures, and give them their common names. The big ones are these: Chapter 11 is reorganization. The financial structure are changed but the creditors can't just shu...
Why are rappers (and other musicians) allowed to admit to committing crimes in a song? Why aren't they investigated/prosecuted?
They are making art and it's protected as such. Keep in mind music tells stories. Not true ones, necessarily. Treat each song like a new fictional person telling you something.1) It is not much different from a comedian doing a routine or an actor playing a role. It is assumed that it is fictitious. 2) Most of what the...
why do people bother charging, say, $6.99 when they might as well charge $7?
It's a psychological phenomenon that can be called "price attractiveness". Essentially, when someone sees a price tag, they see the first digit, and ignore the rest.Apart from sounding cheaper, there is a second reason for the 1c. Store managers wants the cashiers to give change to all customers. If a purchase comes to...
How is it that people can have fun playing a mindless/monotonous game such as WoW, but when it comes to doing homework or having to write a paper then they dread it?
People like getting positive feedback on their actions. Playing WOW you're constantly getting little pats on the back. 100XP for killing this monster, 1000XP for completing a quest, gaining a new level for getting a bunch of XP, getting a magic sword for killing a dragon, etc. The random nature of loot-drops also pushe...
Could a bank go bankrupt? Has it happend before? What would happend to the people's money or loan?
The answer is yes, banks can and do go bankrupt. In the event of bank failures on the scale of the Great Depression, in real terms FDIC insurance would mean very little. While a bank may fail, people who have borrowed money from that bank still have the obligation to repay the outstanding balance and interest. FDIC ins...
Why the stock market closes at night?
The stock market in each country closes at night, but a stock market is always open somewhere in the world People want to go to sleep without worrying that they have gone bankrupt overnight, and banks don't want to pay staff double to work unsocial hours. Incidentally, bank workers in Hong Kong sometimes have stay at w...
What makes days feel like they're moving faster than others?
This can depend on how many things we're focusing on or dealing with but is also highly subjective Fundamentally the more new things we're focusing on means our brains pay less attention to the passage of time If we're focused on a single thing then our brain pays more attention to the passage of time Another aspect is...
Differences between A - & A +, ect
When I was in school, a grade of 90-93 was an A-, 94-96 was an A, and 97-100 was an A+.The major difference is the effect on a GPA. An A would count as 4.0 to the GPA. An A- would be something like 3.7. B+ would be 3.2, and B would be 3.0, etc. The scale is usually set by the school or the university and it can vary be...
Why are orange and purple as clothing colors not popular, but blue and green are?
Personally I don't like loud colors but it may be because orange isn't a flattering color to most complexions. I'd say that purple is a bit more popular than, say, beige or gray.
How would human bodies have evolved differently if the earth had half as much gravity as it does now?
If gravity was 1/2 then the atmosphere would be vastly different so all life would have evolved differently. Your best bet is to try /r/askscienceGood question, but you might do better in /r/askscienceThinner, more brittle bones, taller, faster blood-clotting rate
How the heck can a used truck owned in Texas end up in Syria?
Hooray, I'm useful. I used to work at the Port of Baltimore. My job was silly, and ultimately useless but it did let me travel all over the port and see how things work there. We had a company that leased out a fairly large parking lot that did nothing but ship used cars to Africa. Theres a high demand for cars and tru...
What exactly makes cheap beer taste much worse than something more expensive?
Without going into too much detail the flavor of a beer is determined mainly by types of grain used, type of yeast and types of hops . "Watering down" beer is actually a bit more complicated than it might sound. The amount of alcohol will be determined by how much sugar is available to the yeast and making stronger bee...
How has civilization and daily life as we live it not ended yet, and what's keeping world tensions from boiling over now?
The news is hyperbolic, because "everything is pretty OK today" isn't a very interesting story. The world is a very big place, and with almost 7 billion people, most of these mass killings and epidemics are frankly small stuff for the world as a whole. Ebola might be a very terrifying thing if you're living in West Afr...
Why is it so hard to predict events such as volcanoes and earthquakes even after all of the research into them?
It's because they are a result of very slow forces, and so the margin of error is enormous. A storm system is the result of a few days worth of events that change quickly. A week out, the forecast may be off by a day. The day of, the forecast on when rain arrives may be off by a few hours. But when we are quite literal...
Why is a cars towing capacity so much different then the amount of weight it can carry in the trunk?
The weight limit in the trunk depends on the suspension. The towing weight is supported by a trailer and the only force needed is forward movement.It's not just cars animals have the same limitations. You can probably carry several dozen pounds, but you can pull hundreds of pounds without much more effort. A quick exam...
Would the Death Star have its own gravity?
yes it would, slightly. The first Death Star was 160 kilometers in diameter,[1][2] while the second Death Star was 900 kilometers in diameter.[3] _URL_0_ earth's moon is 2100 km in diameter actually, and mass scales with ^3 so maybe the death star wouldnt be as important as you think it might. a VERY small moon. maybe ...
