Is the sun actually yellow?
the sun is white. it's just tinted yellow from the sky, it's also why the sky is blue, the sky diffracts light.here is a great video_URL_0_the sun looks red at sunset because of the atmosphere. the suns emits a lot of light, not all of it is visible to us humans, but we will see it as white if we were in space.while it is white to use there is also a lot of infrared light and UV light that it also emits, so it really isn't white. it's more like star colored
Why do i keep getting acne when I have showered every day for 4 years and have a healthy diet/work out? Im a 18 year old male
Not a doctor here, but maybe you should see a dermatologist if you haven't already . A lot of acne in adolescence is caused by androgens being released in the body, such as testosterone . Sometimes acne is deep in the skin tissue . Sometimes, acne can be caused by bacteria in the skin, not just hormones or unhealthiness or uncleanliness. If this appears to be the case, a dermatologist might prescribe an antibiotic such as Minocycline, or Isotretinoin . However, a doctor would not prescribe Accutane unless you had severe acne and they'd tried basically everything else. It has nasty side effects. If the acne is not caused by bacteria, you will probably just be using some sort of topical cream . Remember that there is no cure for acne -- there are only things you can do to prevent it.
Why are phones so much more expensive than other mobile technology???
Miniaturization. It's the same reason laptops are more expensive than desktops. It's pricier to make things smaller. To a lesser extent, Steve Jobs set the price of the first iPhone based almost purely on his gut feel of what people would pay. It seems to have stuck
why do pens dry out if you leave the cap off even though most caps have holes in the top?
**TL;DR:** Air, humidity, and heat circulation levels. Air has two ways of drying out stuff. The first is through simple "Brownian Motion" - the effect where absolutely still air has individual particles that move around and when they hit some water, knock some loose and evaporate them. This doesn't work very well at all when the air is already humid . The second is through general motion, like if a breeze or wind is blowing and pushing ALL SORTS of molecules past, say, a pen's nib. This really affects stuff if the air is warm, and it really steals a lot of water or light oils from something like inks, soaps, or gels, particularly if the air isn't already packed with moisture. Putting a pen's nib in a cap with tiny airholes pretty much stops all breezes and causes the small bit of space around the pen's point to stay full of water already so more of the pen's ink won't dry up and crust everything all up when you try and write with the pen the next time. There's just not enough air circulation to really dry the pen out.The other thing to note is that many pen caps—particularly for felt-tip pens that *are* at risk of drying out, because of the type of ink they contain—have two sections, one inside the other. The inner section is usually fairly small, and is designed to form an air-tight seal around the tip of the pen to stop it from drying out. The outer section is much larger, so it's easier to grip. Holes are usually moulded through this larger section, so that if the pen cap gets caught in a child's windpipe, air can still pass through it, supposedly reducing choking risk. These holes go around the inner section, so they don't affect the ability of the inner section to seal the pen.
How does Supply and Demand work when the good is virtual, like steam games?
In this case the supply is essentially infinite, but demand isn't. As the price charged increases, the demand will decrease as less people are willing to pay that price for the game. It works out that there is an optimal point where enough people want to buy the game at a high enough price where revenue is maximised. Above this point, the price increase doesn't cover the number of people who will no longer buy the game.Im pretty sure Steam still has to purchase the license keys from the developers. I remember a year or two ago Steam actually sold out of Star Wars Battlefront II and had to contact the developers in order to secure more keys, so the games are treated as actual commodities.
Why do you get the feeling of throwing up when you're hungry?
Your stomach is constantly producing acid and sometimes when there is no food in your stomach, there is too much acid and it causes a feeling of nausea', "How can people eat when they wake up in the morning? I don't get hungry until about 4 hours after I wake up in the morning, and I don't eat anything before I go to sleep, maybe drink some water.
When our nails grow, what stops the skin at the base of the nails from stretching and breaking?
It does stretch and break, but the nail is moving slowly enough that the tiny injuries and repairs happen without you noticing. The growth occurs under the small patch of skin at the base of the nail. The rest isn't actually alive, it's just hard protein, similar to hair, working its way across the top of your finger. The nail bed constantly adjusts as it works its way out.
Why do cell service providers charge so much for data?
For two reasons. 1. They can. They want make more money. 2. To discourage people from using too much data, and therefore making it slower for everyone. Wireless data doesn't cost to much to produce, but there is a limited quantity of it.
Why do people with memory loss remember their childhood in such detail but forget recent events like their grandchildren getting married?
I'm not an expert on a scientific level, but I worked in an assisted living home that specialized in advanced forms of dementia for over a year and this is what I picked up in my time there; The brain forms thought and memory with physical connections points. And each time you reference a memory, you thicken and strengthen that connection in your brain. So, 70+ years of walking, talking, chewing food, sitting and standing has built those functions up to a pretty robust level.The same goes for memory. You think about the time you were 7 years old and fell off a bike and broke your arm, and you've given your brain years to solidify that connection and memory. But now comes Alzheimer's disease. And this condition will physically deteriorate your brain over time, eventually to the point of shutting it down altogether. But the connections that are the first to go are the weak, recent ones; what you had for breakfast. Who came to visit you last week. Which grandkids got married last month. These memories haven't had time to build any strength before the disease weakens and breaks them. And that's why older memories tend last, and new ones fade first.
Double and single action trigger mechanisms in revolvers and the differences between the two.
In a double action, when you pull the trigger, the hammer moves back, and then is released, triggering the primer in the bullet and firing the gun. Alternatively, you can pull back the hammer manually, which then makes the trigger pull much shorter and lighter . In a single action, pulling the trigger only releases the hammer, and you have to manually pull the hammer back before each shot before you can actually fire the gun.
Envy and how to use it
No, Jealousy in the classic sense is far different than Envy. Envy is simply looking at something and wishing not only did you have it, but the person possessing it did not. Jealousy often consists of a combination of emotions such as anger, resentment, inadequacy, helplessness and disgust. Envy is simply the objective want of something. Being jealous involves fear and anxiety over not having. Although Envy in the series is much more similar to Jealousy, it still fits the definition of Envy for most of the show. And Envy is the deadly sin, not jealousy, and each one of Father's creations is named after a cardinal/deadly sin. Greed, Gluttony, Wrath, Lust, Sloth, Envy and Pride. It would be like replacing them with Indulgence, Hunger, Anger, Horniness, Laziness, Jealousy and Ego. While we all associate the former with the latter, they have different definitions, and don't hold the same kind of pantheon that the 7 Deadly Sins do.
Explain to me the Voter ID amendment.
The proposed amendment to the Minnesota state constitution will require voters to show photo identification at the polling place before they are allowed to vote. It further stipulates that the state government should be required to, at no cost, provide an acceptable form of photo ID to eligible voters. The argument in favor of the measure is that it would make it very difficult for one person to go to the polls, claim to be a different person, and essentially "cast that person's vote" for him. The argument against is that *who does that, seriously?!* and also requiring voters to apply for, be approved for and carry with them a state-issued ID is an unreasonable burden that will have the effect of disenfranchising at least some Minnesota residents.
Why do I feel physically exhausted after an argument, even if I argued calmly?
Because any sort of conflict triggers the 'fight or flight' response. [Wikipedia] Fight-or-flight response - _URL_0_
Why is it that there seems to be a new revolutionary breakthrough in fighting cancer every week, but cancer isn't cured yet?
Because there are hundreds of different types of cancer, and thousands of different subsets of possible progression. Cancer is just your own cells dividing unconstrained, so every individual case is absolutely uniqueCancer is not caused by one single etiological factor, but rather complex overplay of n number of agents taking place in defined pattern and over this we have many different types of cancers leading innumerable theories on how this happens and how this can be cured/prevented. this [image] might help you understand how science progresses not in cancer research, but in general.
How can colleges like UConn justify raising tuition of students, while paying their coaches for their sports inordinate amounts of money?
According to [this article], in 2011 men's basketball generated almost $14M in revenue, netting the athletic department almost $4M in profit. Football and Basketball effectively fund the entire athletic budget. People only go to watch winning teams. So yes, the capital gained supports the pay.Athletic departments are completely separate from the university when it comes to funding. They raised your tuition because they can.High-profile D1 sports teams generate a lot more revenue than they cost to fund, and that money goes back to the school to fund other extracurriculars. They're actually subsidizing your tuition - not the other way around. I get that it's somewhat intellectually irritating that the coach makes more money than department heads and your tuition rises. But as long as sports draws larger audiences and sells more stuff than the arts and sciences, so it goes. The debate team unfortunately doesn't sell enough jerseys or TV rights to people outside the school.The UCONN athletic program put UCONN on the map and has brought in more money and new academic buildings that has made it a top destination. Coach Calhoun turned a somewhat low grade educational university into a school at the level of Rutgers or Syracuse.Before men's basketball was popular and competitive at UCONN, their admissions were almost all in-state and they were very small. After 1999, when they beat Duke for the NCAA Championship, their out of state applications increased by an absurd amount. Out of state students pay more in tuition than in-state students. Because of the growth, the school was granted like $2 billion to build up the campus. Most of the main UCONN campus has been built in the last 15 years. Men's basketball is the best thing that ever happened to UCONN.
What is Dungeons and Dragons
If you play WoW, you have played D & D on the computer. Dungeons and Dragons is about the same game. When the game was first made it was new and exciting because it was a role playing game with dice and adventure. The rules read like a mortgage contract, and are as detailed as a spec sheet for an aircraft carrier. Don't get me wrong, I played D & D when I was younger and before there were computer games like Super Mario Bros. It is an adventure game in which the players explore worlds created by Dungeon Masters . You fight battles, find gold, level up, learn magic and reach spiritual nirvana. Risk and Monopoly are good games to waste away a rainy Sunday afternoon. D & D is a good way to waste away a college career. You roll dice to move your player. You roll dice to see if you win a battle. You roll dice to determine if you level up. It's just like any other game in that respect. The difference is there is a ton of dice and it is an open world dice game. What killed D & D is open world video games like Grand Theft Auto and other games popular in college like Hold 'Em and Hearts.
How was Voldemort able to run a successful "Pure-Blood Only" campaign if he himself was a half-blood?
He found out and killed any connection with the muggle side of his family. Kept it a tight secret and although it was suspected no one really knew.Did you even read number 6?', "It's not like his parentage was well known, he was an orphan after all. Besides, no one was going to call him out on it and risk getting murdered.It might be an allusion to Hitler . Hitler had no papers proving Aryan ancestry and may have been fathered by a Jew. Not trying to start a debate on that subject, but it does have historical precedence.
Why emigrate illegally? Why do people not go through legal channels to enter a country?
There are a limited number of spots and demand far outsizes supply. The process also can take years, even decades depending on personal situations and costs significant amounts of money. Many people come to the country only to work so they can send money back to work. Waiting that time quite literally costs them money so there is no incentive. Others who are fleeing their old lives simply feel that they can't wait the years it might take to get a legal spot or simply can't afford it.It depends on a variety of factors. On a *local* scale, it's usually to do with rules around education and training. Countries typically don't want "unskilled" workers entering their jurisdiction, because they will [probably] have a hard time finding employment, and - as a result - could become a drag on the economy. Of course, defining someone as "unskilled" is another debate in and of itself. But it's true that many of them haven't got university degrees, etc. On the *global* scale, it's because the idea of a "queue" doesn't really exist. Some countries don't *allow* you to apply for visas/passports, etc, unless you fit directly into a narrow set of criteria. Even then, the process can take years and years, and it's not always on a \'first come first serve\' basis. So - for many people - the only way they *can* get out of a country is to leave "illegally" .I'm guessing that migrant workers often cannot afford a lawyer.
Why do international calls cost so much? Both landline to landline and mobile calls
Just a guess but probably because they can. How come there are fees for buying sports and concert tickets? You're just paying a fee for paying a fee. It makes no sense but people pay anyway.
Why does a word look unfamiliar if we stare at it for a long time?
A word written down is on its own just meaningless symbols to represent an idea, emotion, place etc. The longer you just stare at the word itself the meaning is peeled away leaving you with the symbols alone. The same can be experienced by repeating a word over and over again. After just a short time it will sound not only different but foreign and even hard to correctly pronounce. I hope this has helped. Edit: spelling and grammar
Why is there such a larger concentration of land mass in the Northern Hemisphere?
There is no reason, it just turned out that one hemisphere has more land above sea level than the other. Keep in mind that the designations of "north" and "south" are human-made, you could easily swap the names around or flip the map: _URL_0_', "You also have to keep in mind that the most common world map, [the Mercator projection], is stretched out weirdly and can't be used to compare sizes of continents in the northern and southern hemisphere. Africa for instance is a far bigger than it looks and Greenland is a lot smaller. Greenland is actually about 1/4 the size of China. Here's a picture of the actual size of Africa: _URL_2_
Why do things like paper and clothing become transparent when wet?
Paper and most clothing is made of long chains of molecules that will attract and loosely bind water. When they get wet the structure of the molecules that make up the paper or cloth changes slightly allowing more light to pass.
Is streaming digital data essentially "intelligent electricity"?
Not any more than the electricity going through a phone line is "audible electricity". Its all just a sequence of electricity, making sense of it comes with the encoders/decoders on either side.If I had a light that I flashed to tell a message ) would you call that intelligent light? At a very basic level that's what happens with the electricity in a data wire. Its a lot faster and much more complex than Morse code, but it uses the same idea. High voltage and low voltage instead of dot and dash.
How do insurance companies deal with voluntary organ donations?
The recipient pays all costs for the donor in the US. One or two blood tests and a doctor's visit may not be covered by the recipient, depending on the exact methodology used by the specific transplant center. Source: Related to a donor and a recipient. The donor [or insurance] paid all costs except for one preliminary blood test and a 6-month post surgery followup visit.
Why do 4 year-old's think Dinosaurs and Trucks are so cool?
I think it may be down to the fact that they are aware that they, themselves have little in the way of power, so things that are inherently powerful, may appeal to them, as something to aspire to. I'm not certain though. Also, I'm 34. Dinos are still badass.
How bacteria appears in its enironment?
There are two ways salmonella can get in eggs. One is if the chicken has salmonella on it's ovaries or in its ovaducts - that can get an infection in the egg sack before the shell is formed. The other is if there is salmonella on the shell, like from the chicken's own poop. The eggs are washed and sanitized after they are collected to help prevent this from travelling through the pores in the shell in to the inside of the egg. Unfortunately, that also removes some of the protective coating of the shell, so they are vulnerable to more infection. Eggs infected from the inside don't tend to start with too much of the bacteria in them - not enough to make you sick. This is why eggs are cooled quickly after being collected - it prevents the bacteria from reproducing, both that was already in there or gets on the shell after washing.> Or is it in the egg "by default"? First the chicken needs to have salmonella living in it, and then the bacteria can enter the egg as it is forming in the oviduct of the chicken.
How does a sex change, male-female/female-male work?
However the patient wants and their medical health professionals recommend - every transgender person is going to have a unique experience, as their bodies may react differently to treatments or they may not desire the full range of treatments available. The most common step is for the person to take hormone replacement therapy to bring the sex hormones of their body in line with the levels typical of their identity. Masculine levels of testosterone and estrogen will facilitate development of muscle mass, male-pattern body hair, masculine fat deposits, and some other perceivable traits of masculinity. Feminine levels of those hormones will do the opposite, feminizing the person's appearance. There are any number of cosmetic surgeries that may be performed to reshape bone structure, like filling out a brow or reducing an adam's apple, but these can be costly and can give undesired results if the operation goes poorly or the person is indiscriminate about what will help them to achieve their proper image of themselves. When people talk about Sexual Reassignment Surgery they are usually referring to the replacement of genitals with an approximation of the other kind. This may use existing skin and nerve tissue to retain pleasure, but will not function for reproduction. This treatment, like all others, is not universal as a transgender person may be ineligible for it or may prefer their existing genitals over taking a chance on an approximation. Given the normally private nature of genitals and their common usage of determining someone's sexuality or gender, this is something that unfortunately is often not treated with tact in society, and I fear that there are transgender people who may be unsatisfied with their decision to undergo it after feeling like they had to in order to be seen as legitimate in their desire to live as the other gender.
What is a "sigh," exactly, and why do we do it when we're sad or exasperated? Does every culture sigh?
I don't think it's cultural or even human for that matter. I've heard my dog sigh when he's frustrated", 'There is a great article in the Guardian that discusses this; > Californian scientists have identified the source of the sigh. It is not just a response to sadness, depression or despair: it is, also, they report, a life-sustaining reflex that helps preserve lung function. _URL_0_ It occurs in humans and animals, so would happen in all culturesI might have to dig it up somewhere but there was a good response to this question before as it being a kind of "emotional reset button"', "What about sighs of exasperation? They don't seem so resty to me.
Why eggs, bacon, pancakes, etc are considered breakfast food?
Believe it or not, it was the result of a deliberate advertising campaign on behalf of the pork industry: > In the 1920s, Bernays was approached by the Beech-Nut Packing Company – producers of everything from pork products to the nostalgic Beech-Nut bubble gum. Beech-Nut wanted to increase consumer demand for bacon. Bernays turned to his agency’s internal doctor and asked him whether a heavier breakfast might be more beneficial for the American public. Knowing which way his bread was buttered, the doctor confirmed Bernays suspicion and wrote to five thousand of his doctors friends asking them to confirm it as well. This ‘study’ of doctors encouraging the American public to eat a heavier breakfast – namely ‘Bacon and Eggs’ – was published in major newspapers and magazines of the time to great success. Beech-Nut’s profits rose sharply thanks to Bernays and his team of medical professionals. Before this, [most people at least in North America ate a lot of oatmeal and porridge.] [Edward Bernays] is quite fascinating. He is considered the founder of 'the art of persuasion', using psychology, tricks, bonus gifts etc. to market goods to consumers or just propaganda in general. > In the 1930s, his Dixie Cup campaign was designed to convince consumers that only disposable cups were sanitary by linking the imagery of an overflowing cup with subliminal images of vaginas and venereal disease. _WHAT?_
Why do people wearing clothes made by child labour/slaves treat people who wear fur like monsters?
Fur is easily visible, and is usually worn by wealthy people, so it's easy to criticize. Note that very few people attack strangers for wearing leather, even though it's just fur with the hair removed.
If calories are technically energy, how do they turn into fat or muscle?
Your body doesn't turn calories into anything, per se. A calorie is a unit of measurement regarding energy - one calorie is the amount of energy required to raise 1 gram of water 1 degree . Your fat and muscle comes from things like protein, lipids, and carbohydrates.
Why do days begin in the middle of the night instead of dawn?
Dawn changes everyday, so it would be a very unreliable gauge on time. But I know what you mean, why doesn't the day begin at our current 7am. I'm only guessing, but i'd imagine it would come from what we perceive to be the 'middle' of the day, 12 noon. If that is the middle, then logically the opposite side would be the beginning/end?
why do fridges make such strange sounds?
Refridgerators contain [heat pumps], which circulate heat out of the fridge. These heat pumps contain moving parts, which make noise. [Here's a nice animation of what's moving in a heat pump].
If poverty and crime are almost always linked, why are the ghettos in San Francisco and Sacramento with Asian immigrants have almost non existent crime?
Who says those areas don't have crime? There are Asian gangs that operate in San Francisco and Sacramento.Are you kidding, or just extremely poorly-informed? Chinese gangs have been a *serious* problem in San Francisco dating back to the early 20th century, at least. Go try reading up on, say, the Sun Yee On or the Wah Ching.One difference: Asian immigrants have places to work and a chance to save money and improve their lives. Other poor people often don't have a chance to work in a decent job where they can save money. They might see stealing or selling drugs as a better way to make money . There is still a lot of crime in asian immigrant communities. Although some places like SF Chinatown have less. Asian mafia's will stop some crime in certain neighborhoods, and increase other types of crime that we can't see as easily. A place like the tenderloin in SF has a very large Asian immigrant community - and high crime - but it is mixed immigrants and other poor people. A tight knit community like Chinatown is very crowded and it is less easy for petty crime to happen unobserved. Majority Asian communities are very different in different cities. For example, Philadelphia's Chinatown has lots of crime of all types in it - it matches the general levels of crime of the city and the neighborhoods around it. Boston's chinatown is also a high crime area.Because of the well-documented fact that crime in Asian immigrant communities in the USA and abroad goes largely unreported.LOL this is absolutely hilarious. Asian gangs partially run the drug trade in my city . I don't live in a coastal city, or anywhere near what would be considered a major one. An asian friend of mine since elementary school was mixed up in them. Ended up shot up in the middle of our nice middle class suburb. I actually know more asian people who have died as a result of drug violence than black people, and I grew up in a predominantly black and poor neighbourhood.
Why does the bruised part of an apple turn brown so quickly after its dropped?
The cellular damage allows for oxidization . Read more here: _URL_0_ There's probably a deeper answer about why apples in general oxidize so quickly , but as far as your question goes, the bruise has the same effect as cutting it open does.
What causes our body's automatic reaction to gag when we see or smell rot?
Our body developed this sense of disgust to prevent us from poisoning ourselves. We need to feel sick, or disgusted by rotten, and possiby poisonous food, so we won't even be tempted to eat it.
How does a phone recognize when someone else takes a screenshot of your text/snapchat/etc
The way I would have done it, were I to be developing snapchat, would be to "hook" the Android-provided function for a screenshot. That is, I would program software that forced my code to be ran whenever a screenshot was taken, and, if appropriate, send that a screenshot has been taken.
Why do older TVs have a weird screen effect while being viewed on another camera?
because the refresh rate of the TV screen collides with the frame rate of the video resulting in an "animation" of said refresh rate - the line moving up or down the screen. It's similar to the way rims on a car often look like they are going on the wrong direction on film, or how in a strobe environment water droplets look like they are travelling up instead of down.
Why does Asian porn use censors? [NSFW]
There's a [Quora post] that explains a little bit about the laws in Japan regarding censorship. A more in-depth explanation can be found on this [Wikipedia page]. Essentially, it's viewed as okay to accept that porn exists and people watch it so long as the act itself is censored. Both links I provided give an overview of why that is, but suffice to say that its a cultural thing.
The Vault 7 CIA leaks
Is there anything specific you want to know about? It's a very big leak and one that people are still sifting through - there is a lot of misinformation going around though and I'd love to help people understand where I can to stem that. TLDR: Wikileaks have come into possession of some data from one of the CIA's Confluence servers. Confluence is basically a Wiki for companies and orgs to use to document stuff/work together, so it has a lot of information on their tools and procedures. There is apparently more leaks to come.
Why do film reviewers on YouTube have so many issues with fair use, but those on television do not?
The film clips you see on TV reviews or on video reviews put together by larger outlets are provided by the studios or distributors. There is no issue with fair use, because everything is already cleared. These materials make up a film's electronic press kit . In the olden days, these were sent to the press on tapes, but nowadays, they are kept on special password-protected sites. This is also where film critics get things like hi-res stills and text copies of the end credits. In general, YouTube reviewers don't do it professionally, and therefore lack the contacts needed to access these materials. Lionsgate is one outfit that doesn't require a login for its press site, so you can take a look at what one looks like: _URL_0_ Studios' publicity departments monitor this kind of stuff. When professional reviews use materials that aren't from the press kit, they get a sternly worded e-mail. Source: Years of experience dealing with stuff for on-camera reviews; worked for a stint with At the Movies.
How can our ears pick up the smallest vibrations in the air, but wind isn't deafening?
If it's strong enough it certainly is deafening, but the shape of our ear lobes and canals does a pretty good job of keeping the wind streams out. It's a relatively small canal so big gusts of air blow past it while the intersection of more or less standing air in your ear canal and the shifting air outside can transfer the smaller vibrations
Did those Duracell batteries with the little "press here to see power remaining" function actually work? If so, how?
They did. You'd have to press really hard though, and then the line would fill up/ turn transparent indicating how full the battery was. According to an older ELI5 threat, pressing on the circle's would close a circuit within the battery, which would heat up a resistor. This heat is then detected by the little strip, changing it's color. _URL_0_
How do payroll debit cards "save" an employee money? Why do some places push for them to be the only method to get your paycheck?
Direct deposit costs employers money. It isn't a lot, and it is cheaper than physical checks, but it isn't free. Pay cards are being pushed by the banks and they are generally pretty terrible for the employee. The banks will do them for free or even pay the owner of the company to use them. Some people don't have bank accounts so cashing their paycheck for a fee or using the pay card are the only ways they can get their money.As i understand, there are on-going lawsuits regarding this practice, as it will often impose penalties and fees to the employee trying to access their money. And for employees of the typically low-wage jobs that require these cards, any fee can be a significant amount of money to them.They exist to save the employer money. Saying they save employees money is bullshit - the only case they save an employee money is if they don't have a bank account & have to rely on check cashing services.
When I was a kid I saw side by side (our product vs. theirs) advertising everywhere, what happened to it?
Two reasons why it's not really done anymore: 1) Anything you say about the other product, any use of their brand/trademarks and any demonstrations of the other product will be carefully scrutinized and can potentially get your company sued or in trouble with the FTC , particularly if you make any statements which the other company considers to be false and/or if you do any demonstrations which the other company considers to be rigged or misleading. To be safe, companies generally avoid naming other products or using their brands now, although they may still offer general comparisons to the 'leading competition' and use the other company's brand colors to distinguish it from their own product . 2) There is a saying that goes something like 'there is no such thing as bad publicity, all publicity is good publicity'. It's based on the idea and psychological principle that people prefer whatever is familiar to them and when given the choice between an item a person has heard about before and another that the person hasn't head about before, they'll often purchase the item they have heard before even if they heard about in a negative context. So basically, there is a concern that even though you're associating the other competing brand with something negative , just the fact that you mention the product by name and display their brand can itself inadvertently act as advertising for the competition. Even though it seems counter-intuitive, potentially more people will buy the competing product after hearing the advertisement against it than would have bought the product otherwise.
How does this airfoil work?
The rhomboidal wing used in the aircraft works as a very large wingtip, reducing harmful wingtip vortices that induce drag.
How do cells know what to do when they don't have brains?
Big, complicated, multicellular organisms like us are really just the result of tons and tons of very complicated chemical reactions! For example, blood vessels seem to magically "know" to grow in a pattern that oxygenates every cell. What actually happens is that, during growth, cells that aren't getting enough blood emit a chemical, and blood vessel cells are programmed to grow towards that chemical. A lot of bodily processes work like that; "if _ is detected, grow this direction/do this process, etc."', "Cells don't know what to do period. All cellular actions are based on DNA instructions and chemical balances interacting with super complicated proteins. They swim around, sure, but they're not choosing a direction to swim in, they're just moving, and that helps them because there's more likely to be nutrients where they aren't than where they are because they ate all the nutrients where they are.
What's actually happening when you miss someone so much you can physically feel it?
The threshold between mental anguish and physical pain is quite small. That's pretty much what it boils down to. Any emotional turmoil can inflict fairly severe physical effects as well. It's why grief runs rollercoasters over people.
How my dad can get all of these coupon viruses on his computer so easily when I have never gotten one once.
In my experience, old people have far less an understanding of computers than you give them credit for. Their knowledge base and skill set are NOT intuitive like it is for us. They can't "figure it out". They click on shit. They have no idea what they're doing or clicking on. If they knew, then when you ask them, they 'd be able to tell you. And there's your sign. You can't explain something you don't understand, even if you 've physically done it. And unless they're enveloped in tech like many of us are, they're not going to keep up. Crap will slowly creep in. If it's not from clicking on shit, look at what he did install. If your father installed any freeware on his own, he probably didn't unbundle the malware. This is usually what I find happen. If your father has computer friends, they probably pass their savvy to him, themselves being equally unaware about the consequences of their actions, despite their best intentions. How-To Geek has a recent article on malware, and there are no good ways to protect a Windows PC. You should only run one anti-virus or like scanner software, since they take a HUGE performance hit on your system, and no one vendor will catch even most malware of this categoryYou go to a site, you see a popup window that says "click here for free $$$". Do you click on it? Does your dad click on it?', "Don't give him admin privileges and install adblock.
When I have a sinus infection - why does the side that is plugged change occasionally?
Often it has to do with the way you are positioned. First of all, the sensation of stuffiness you are feeling is due to a dilation of the small vessels that are in the lining of your sinuses . The vessels leak fluid and cause edema of the sinuses, which closes off the opening to the back of your throat. Congestion is NOT due to mucus. Back to your question - even a slight change in position can cause the fluid accumulation to shift sides - if you lie on your left, gravity will move it downward and your left nostril will seem more plugged up. If you then shift to your right, the fluid will trickle into your right sinus and your right nostril will feel stuffy.
whats so special about Cuban cigars, why can't we just make them in the states?
If we could get the Cuban tobacco we could do a pretty good imitation; producing cigars alone is not the problem. It's all in the unique combination of growing conditions found on the island. That's why California Pinot Noir won't taste the same as French Burgundy made with the same varietal grape, all other winery practices being the same.
During WW2 how was post made possible between the UK and Germany?
You go through a neutral 3rd country. For Europe popular choices were Switzerland and Portugal . The British Mail service, in order to avoid appearing to colaborate with the enemy, enlisted the help of Thomas Cook & Son. You would send your letter to a Thomas Cook & Son office in Amsterdam . They would then forward your letter into occupied territories. Strict limits were placed on what could be discussed in the letters the length of the letters , and the way the letters were written .
If images are just data that says what color each pixel should be on screen, then why are some bigger in size than others?
Compression. The maths is a lot more complex and there are multiple ways to do it, but to sum it up, it's like writing that there are "10,000 consecutive zeroes" instead of writing "000000000000 ." . It's kind of like how we write a 9 instead of writing IIIII IIIIThe program you use to make the program is able to compress the file slightly to make it take up less space. So instead of recording info for every single pixel, it stores information for a chunk of them that are all the same.
What was the impact of the Cold War in the Yugoslav Wars?
I'm not a history expert but Yugoslavia was a non allied state which maintained good relations with both the USSR and the United States. After the Tito-Stalin split Yugoslavia liberalized it's economy to an extent, so you could say it was a blend of Capitalism and Socialism; don't get me wrong though, most industries were state owned, it was very difficult to start businesses , unemployment was high, and heavy debts to the IMF only helped in the inflation of their currency. However, the biggest blow was Tito's death and the decade that went by without a figure head like him. Post cold war, the Socialist Federal Republic of Yugoslavia fell down to the ground like a house of cards. There was no Titoism, no brotherhood, only feelings of nationalism arose among the different ethnicities . Started with the Slovenians, then the Croats, then the Bosnians, while Yugoslavia was trying to stitch the pieces together. Yugoslavia could only last as long as the Cold War's duration.
How does paying bail/jumping bail work
It's basically like this: In the time between where the suspect is arrested and charged with a crime, until the suspect has been sentenced to time in prison, community service, etc., that person can under some circumstances be permitted to leave the police station.Usually, somebody has to leave a large sum of money, supposed to cover a bit of the police work included to locate and retrieve the suspect if he/she does not show up for his/her court date. If the suspects shows up, the bail money is generally repaid. There can also be certain conditions put on a suspect being bailed out, like him being confined to a certain house, general area or his movement restricted away from certain places.Bail money is given *temporarily* to the court. It is given back after the legal proceedings unless the defendant does something like fails to show up at a hearing , in which case it is kept by the court . The "X%" thing that you refer to has nothing to do with the court. It's that you can pay someone to temporarily give the full amount to the court, while you permanently give a smaller amount to the bail bondsman.
How common is it for birds to fly into airplane engines? And how do they keep it from happening?
Planes usually fly much higher than birds, so bird strikes are only a major problem during takeoff and landing. Airports employ a number of techniques to spook birds away, including noisemakers, repellents, trappers, trained animals, scarecrows, and fake predators. They still happen though, and big geese can do some real damage at 500mph. > The Federal Aviation Administration estimates bird strikes cost US aviation 400 million dollars annuallyAirports have all kinds of perimeter systems that try to keep birds away, from noisemakers to border collies. Nothing is completely effective. At cruise altitude, planes are above the levels birds prefer. Planes make a huge noise, and most birds manage to avoid them. For the others, well bad things happen, even to nice birds and enginesSomewhat common. They try to avoid birds if possible. That's honestly the extent of it. Any solution other than "fly around the birds" is far more expensive than it would be useful. They *do* try to design engines that don't explode when struck by birds, but that's not the same as engines that can keep running afterwords.It happens. There are many methods to reduce it's occurrence. Mitigations are: * killing birds/destroying nests in the area* training birds of prey to attack* using sounds of predators to scare them* loud noises in general* drones
How are plastic latches made?
Without being able to study this closer it looks like it is injection molded and then the hinges are drilled or pressed out in a second stage. You might just see the dividing line between the two molds at the edges of the piece. In the middle you can see a second plastic piece which have been ultrasonically wielded, likely to make the center hollow and therefore lighter but still durable and comfortable to hold. It also hides the injection marks and the witness marks but they did not do a good job of cleaning up the wield, likely because it is on the inside and hard to get to and would not be that visible while in use.I don't know the exact process, but there's a few options for this sort of design depending on the plastic. Some types can be reheated during processing to squeeze and mold them others are one-shot materials that won't melt again . 1) the black plastic has enough flexibility that it can be bent into place by a machine. 2) the black piece is made first, then coated and placed in another mold and the clear plastic is injection molded into it - or vice versa. 3) the pieces are assembled hot or heated during assembly and stamped into shape.
Why does stuff get dusty?
Your skin is constantly dying, falling off, and being replaced. The dead skin becomes dust that gets blown around and finally lands on stuff.
What does "agent has interest in the property" mean?
> Is this just stating that as an agent they also might make money off the sale because the own it? That is pretty much it. Normally the representing agent gets a few percent commission. In this case they want to disclose a possible conflict of interest, letting you know they have a financial interest that might cause them to behave differently than a regular agent. I wouldn't be too concerned, just make sure your agent is representing your interests, and is not too cozy with the other agent.
why it is better to absorb essential oils and minerals from food rather than supplements?
From what I know it’s not because it’s “better” but because with a well balanced diet you should be getting all of the minerals and vitamins you need , and those foods are better for you . So when you are lacking in certain vitamins because of a poor diet the best solution isn’t to keep the poor diet and pump you with vitamins from other sources; it’s to get you on a healthy diet where you will have everything you need. Hopefully that answered the question; If I’m wrong please let me know!
Why do bones last so much longer than flesh after we die?
I think most importantly, tissue will be eaten by microorganisms, bones won't. Once all the water evaporates off, bones are ~70% made of a mineral called hydroxyapatite, which isn't going to decompose, at most it'll become fragmented and ground down. Flesh, on the other hand, while mostly water, is made of proteins, lipids, some carbohydrates, which break down quite easily. E.g., the distinctive smell of rot is a direct result of proteins degrading, and this gets noticed pretty early on. Plus, any "structure" holding things together falls apart pretty quickly in flesh--first is the cell membrane, because when you stop having a way to get CO2 out of the body, things start becoming acidic, and cells rupture. Eventually, you get left with a bunch of goo, and nothing holding anything together.Flesh is tissue, and when the person is living, the flesh is much easier to lose, cut, etc. Plus flesh decomposes much easier due to microorganisms, bones don't decompose nearly as fast, that's why it's possible to find preserved bones from so long ago, but not skin.
Stage fright at the urinal. Why does it happen?
Your body has a sympathetic and a parasympathetic nervous system. One is the fight or flight, and the other is sometimes called "rest and digest". Peeing falls under the digesting side , and thinking the guy next to you is examining your junk can trigger the fight or flight one, which makes everything tense. They conflict.
Why do the ants take my toenail clippings and what are they doing with them?
Without more information regarding the type of ants that are removing your clippings, it's difficult to say. However, all ants require a diet of sugars and proteins. Nail clippings will contain skin sheddings, oils, etc. To my knowledge, no ants eat keratin . However, it is likely that they are interested in the other biological material that is attached to your clippings.
Why is one currency worth more than another?
It's all to do with perspective. Let's say you and two other friends want to trade. You 've got oranges, one friend has apples and the other has peaches. If you want a peach, you could just trade one orange for it. But what happens if you think your orange is worth more than a single peach? If your friend with apples really wants oranges too, he might be willing to give you multiple apples for a single orange. If there's a higher demand for your oranges, you can sell them for more. This is essentially where the "worth" of a currency comes from. Traders take a lot of things into account when buying and selling currency. Things like having a strong economy will increase the value of currency, by driving up demand . If traders feel the currency is high risk, there will be low demand which means in order to sell it you have to drop the value. The external value of a currency isn't everything though. You can buy about 10 Norwegian Kroner for one Pound Sterling, but things in Norway cost about 10 or 20 times as much.
How is needing smoke breaks during work not considered as a drug addiction impacting your ability to focus on your job?
Technically smoke breaks are only legally required within the confines of the official breaks. A company doesn't have to allow extra breaks. But employee morale is something that does need to be considered. This isn't the most karma I've ever had from a post but it is by far the most commented on comment I've ever made. Really was not expecting that but thanks for reminding me that it is sometimes the last thing we expect that reminds us we aren't all invisible cogs plugging away at the world unnoticed.
Why are some court cases allowed to be filmed, but others aren't?
In the U.S., it very much depends on the state and the individual judges. Some states have bans on recording with cell phones, some allow them with permission of judges. You would have to look up the individual state for the rules. Here: _URL_0_
why do they call it elevator music if there never really is any music in elevators?
The answer's pretty simple, [it **used** to be played in elevators], but has been phased out as we 've gotten more comfortable riding in little metal death traps. > As skyscrapers began popping up in urban areas around the world, the necessity of elevators shot up. As the story goes, early skyscraper denizens weren’t totally sold on this idea of getting into a tiny box and being pulled up a very tall shaft. To help calm riders’ nerves about getting into elevators, building owners would pipe in soothingly bland music, and soon “elevator music” became shorthand for any boring, non-threatening instrumental music. The real question is why muzak is primarily known as "elevator music" considering its also used in malls, department stores, restaurants, telephone hotlines, workplaces, and even the freaking White House back in the day. I 'd guess it was because: a) your mind is elsewhere when you're out shopping or eating. In elevators, you don't really have anything to do but wait and take in your surroundings, music included. Mall music goes in one ear and out the other, but you actually listen to elevator music. b) It's use in elevators was more common in New York City, where most of America's media is based. The use of the phrase in TV, movies, print etc. then spread to the culture at largeIn some old buildings they do have music in the elevator still. It was always cheesy inoffensive "muzak"it was much more common in the late 50's-70's to hear background music in elevators. that was where it got it's big start, hence "elevator music". you still hear it in some stores, offices/waiting rooms, and other places like "hold music". as /u/slash178 mentioned it was often referred to as muzak . at the time, muzak was mostly soft, instrumental light jazz or orchestral versions of popular tunes.
Why Couldn't we create a machine to just split CO2 down to its component atoms?
This can actually be done, but it's not energy efficient. CO2 is like a dude laying in a bed after a threesome with two Swedish supermodels. He already blew his energy load, so if you want to get him away from the likely pinnacle of his sex-like, you're going to have to put in a lot of effort from an outside source to get him out of that bed. Even then, he's going to resist and protest, resulting in a lot of wasted effort on your part that might be better spent making yourself some bacon.
Why does your body allow fungus to grow on your tongue? If it serves a purpose, what is that purpose?
Your body is constantly host to low levels of all sorts of bacteria and fungal spores. Especially in warm wet areas where such things thrive best . These things are everywhere, and it is not like your body can completely ward them off. Usually though, if your immune system is working as it should, all these random spores and bacteria that ended up on your body would be dealt with and nothing bad would come of it. When your immune system gets disrupted though , these random fungal spores and bacteria aren't properly kept in check, which is why they then actually grow to a point where you have to experience an infection of them.
Why is it so much easier to fall asleep in a napping scenario and so difficult to fall asleep for a night's rest?
You take a nap because you are already tired before engaging in the nap. You go to bed at night because you know you need to in order to have enough energy for the next day. So sleeping because you want to vs. because you are supposed to.You'll probably get a more accurate answer in /r/science or something. I doubt you need a child's answer to this question to understand it. Just a heads up. */r/askscience", 'This happens to me all the time. I'll be able to fall asleep in a snap throughout the day. But as soon as its an appropriate time to sleep, I lay there for an hour. I think its because with a nap, you dont care if you fall asleep or not so its easy to. But at night, youre telling yourself "okay lets fall asleep."
Why is it a negative thing to be over-qualified for a job?
If you're overqualified for a job, there's a good chance you'll leave when something better comes along. Employers prefer stability, particularly because some jobs have a cap on how high a person can perform.
Why is emulation so difficult? Especially sound
Emulators take the instructions from the game that were originally intended to be interpreted by the console, they then have to find a way of mimicking these behaviors on a modern computer. This is very difficult, not only do you have to learn how the game worked based off the assembly instructions you also have to learn how the console operated on its lowest level as well, you can easily wind up in situations where you make an effect in one game work only to have the same effect not work in a different game, and when you patch both of those, 6 other games stop rendering entirely. Sound is simply the least important part, so it gets least priority.
What's the difference between muscle implants and transplants. Is it possible to have a fully functioning pectoral muscle implanted/transplanted?
the word implant generally refers to non-organic things put inside the human body. muscle implants are much like breast implants but to make your muscles look bigger. muscle transplants are different. transplant means something taken from someone else, or somewhere else on the body. muscle implants generally don't replace entire full muscles since that would be pretty risky, they usually aim to transplant smaller amounts at a time to restore lost functionality
Why, unlike other nineteenth century accessories like stocks and monocles, are neckties not yet obsolete when they have no particular purpose?
They have always been decoration / fashion items not functional items. Monocles are replaced by glasses, contacts and laser eye correction as vision aides. You don't need to keep your pants up with suspenders any more since elastic waistbands and belts generally replace them. you don't need to keep your socks up with straps anymore also due to elastic in them. The difference is things you have to where for function vs things people where for fashion. This doesn't stop some people from putting on old function items for fun and fashion however.
Why do animals jump in front of cars?
I want to know why birds seem to fly right in front of cars directly across the road. I'm pretty sure it's a game they play to see who can get closest without getting hit. "Yo Tweety, you're up on this tractor trailer. Bet you can't graze the grill with your wing". Bam.I think it's several factors but probably the biggest one is once startled, they have no idea just how fast your car is traveling and think they have time to go back in the direction they originally came from. Deer often don't notice you until the last moment because your lights and the sound of your car approaching build up gradually in a way they ignore until it's too late. Squirrels use the same darting/stopping/darting motions that work well with their natural predators but really suck with automobiles. It's also random, a startled animal *may* dart out under your vehicle, or it may go the opposite way -- only the aggressive few are intentionally headed for your car.One night, I was driving home after midnight when I saw two does crossing the road. I avoided hitting them, but as I started to speed up, I hit the buck that was chasing them. It was late October, and the rutting season was in full swing.
The difference between a Polar Vortex and Wintertime weather?
The polar vortex is not weather, its a persistent atmospheric state around both north and south poles. But if weather conditions get too weird too fast, they split into multiple weaker vortexes and the very cold weather confined to the poles spreads out
Why do my mental emotions feel physically painful, especially in my chest?
It's because mental emotions cause the same physiological responses as physical pain would cause you. The fight/flight response increases the rate of flow to the heart, changes your breathing etc, so it makes sense that your brain associates that sense of fear/anxiety with physical pain. The more that you allow the brain to reaffirm that association, the worse it will get. You have to treat depression/anxiety/fear/anger like any other feeling - and accept that it will pass. Once your conscious brain can force that on your subconscious brain, the physical pain won't be so bad.Your emotional body affects your physical body. . It can do harm, maybe your body has some harm, so its easy to trigger the bad feelings there. You can work on both sides to solve the problem.
Why do tennis players makes a great deal on selecting which ball to serve?
Newer balls move faster through the air than older balls that have fluffed up. So depending on their preference, players will choose the ball that will give them the biggest advantage. For example, a player whose game revolves around retrieving would probably prefer a slow fluffy ball.Amouny of fuzz affects spin. Spin is control. Control is the key. Fuzz wears off quickly. This is why they get new balls every seven games.
Why aren't things like Caffeine or Nicotine Scheduled (controlled) substances?
I think it's not controlled in this way because caffeine and nicotine in themselves are not harmful and extremely difficult to overdose on in their "natural" form. By that I mean, the amount of caffeine in tea or coffee and the amount of nicotine in tobacco. They also have less of an effect. Caffeine and nicotine may give a noticeable stimulant reaction, but it is slight compared to others. That may be some justification to the DEA ruling. Also, tax dollarsCaffeine is actually not considered to be highly addictive. If you cut caffeine cold turkey you might have a day or three of headaches. That is not severe addiction. A severe addiction would include fevers, vomiting, violent shaking, loss of ability to focus or at times even complex thought, fits of rage, etc.
Physics being tied to framerate in game engines
The physics engine operates in discrete steps. One simple way to write a game loop is to process input, advance the physics one step, render a frame, and repeat. If you do this, then the timestep for the physics is tied to the framerate. You can measure the framerate and set your timestep accordingly - but some algorithms require a constant timestep. If you have physics tied to framerate and you require a constant timestep then you end up capping your framerate at a fixed value as a side effect. There are other ways of doing this - for example, you can decouple the physics engine from the framerate, always advancing the physics by the same fixed time step, but not necessarily the same time step as used for the rendering. Since the time at which you want to render the simulation and the last calculated state don't match, you have to interpolate between the two nearest states to get smooth animation. However, if your entire engine is built with the physics simulation coupled to the frame rate, this is quite a major change to make. Also see [this link] for a more in-depth explanation of the topic.
Buying country debt at negative taxes.
I'm going to assume you mean interest rates here, not tax rates. The general idea around government interest rates is that government bonds are the safest form of investment there is - after all, the government can just print money to pay you back, so the odds of not getting the promised return are near zero. Thus, all other forms of investment are judged against government bonds, with interest rates being an assessment of how much riskier those investments are comparatively . By manipulating interest rates, the government can control investment in the economy. If it feels that there is too much inflation or too much investment, it can raise interest rates to pull money out of the economy . If it feels that there is too little inflation or too little investment, it can lower rates to put money back into the economy . Negative interest rates come about when even a zero percent interest rate isn't enough to counteract low investment or low inflation. The opposite of inflation - deflation - is actually one of the worst things that can happen to an economy, because money gains value just by sitting around doing nothing. People don't want to spend today because they will gain more value by holding the money. When this happens, people will flock to zero-interest government bonds because they gain value and are still perfectly safe investments. If this happens, the only thing the government can do is introduce a negative interest rate - have your money _lose_ value through the investment. This helps to encourage people to put money back into the economy which is one of the few things that can stop a deflationary cycle. So, to your question, there is nothing in it for investors but that is the point. The government doesn't want you buying bonds at that point - they want you putting your money back into the economy.
The difference between an HMO and PPO dental plan?
Finally a question I can answer confidently =) An HMO is a plan that utilizes a managed care company. Usually a third party that oversees your healthcare, or in this case, your dental needs and maximizes your coverage. With an HMO, you choose and are assigned to your primary dentist. That individual takes care of all your routine needs. HMO plans have co-pays that are due at time of service which could range from $5 - $50 depending on the plan that is purchased by your company and there are no other fees other than your premium Additional work would require referrals from your primary dentist and you see the providers that they assign you to see who are generally providers who have contracted with that specific managed care network. A PPO plan allows you to choose who you want to see regardless of a referral. However, these plans do not work on a set copayment and are usually a percentage. This means that you would pay a share of the cost of services every visit. You would also have a deductible, which in some cases, dental offices will require upfront before any serious work is done. It's really important that regardless of what plan you choose, you review what each plan covers and what your expected needs are. For example, if you need to have several teeth pulled and will need crowns placed, than you want to pay close attention to your cost of those services. If you have any questions about what you're reading, I'm more than happy to help. Just message me!
Why do my cheerios make a "crackling" sound in my milk?
When you pour milk into your bowl, the cereal absorbs the milk. As milk flows into the crispy kernel, the liquid puts pressure on the air inside and pushes it around. The air shoves against each pocket’s walls until they shatter, forcing out a snap, or a crackle, or, as you, know, sometimes a popyou might be eating rice krispies instead of cheerios.
Why do Sugar Babies (the candy) feel more and more gritty the longer I chew them?
Because as you chew them, you are changing the hard-ish sugar/wax coating from big pieces into grit that gets mixed up with the softer inside part.
If I touch my forehead skin with my fingers, which touch feel will be received faster into my brain?
The sensory information from your forehead will reach your brain faster, however, you will perceive both sensations as occurring at the same time. The reason why signals from your face reach your brain faster is because they have much less distance to travel. Somatic information enters the brain through one of the cranial nerves, while information from your fingers travels up your arm, into the spinal chord, and then up to the brain. Because information processing takes time, your conscious perception of touch is slightly delayed. Your brain is able to recognize that even though the information from different areas arrived at different times, they still represent the same event and thus will be interpreted as happening at the same time. Sensation and perception are not the same thing, and I think this question illustrates that point wellYour brain receives everything in intervals, so you 'd "feel" them both at the same time. But you can kind of mess with it if you do something really fast in an alternating fashion. For example, take one hand and tap your index and middle fingers on a table really fast, one after the other. Edit: Actually, I think the brain receives everything at different times, but only "tells" you what was felt in intervals. Someone else will have to confirm that, though.
What is the cause of the bee population decrease that's being observed, and what solutions are being implemented?
This vide explains it best - _URL_0_ TL;DW - There are multiple theories regarding Colony Collapse Disorder . The most popular theories are changes in earth's magnetic poles , climate change , or contamination of bees from pollen of plants sprayed with pesticide ", 'Besides the other explanation, bees are subject to parasites, mites, other marauders, etc. They have been subject to these forever. Bee keepers stress hives for their own purposes, transport them to fertilize crops, take their honey, etc. It may be that these stresses collapse domestic colonies.
How does the body taste/smell things when you think of them?
Basically when you first interact with something it will trigger a neuron in your brain to fire, neurons work in much the same way as transistors in a computer, they can be on or off. When you eat a steak your tastebuds sent a signal to the neuron in the part of the brain responsible for short term memory this in turn activates other neurons in your brain basically creating a binary code for stake. When you think about steak or receive a similar input again, it will fire off the same sequence of neurons. Over time the pattern gets repeated and the neurons responsible for seeing/eating stake get better at communicating with each other resulting in your ability to "taste what you see". That wasn't as basic as I wanted it to be but hey the brains a big ol\' complicated mess
Why do carbonated beverages have streams of bubbles coming from seemingly nowhere?
The bubbles are carbon dioxide gas. The gas is initially dissolved in the liquid, like you would dissolve salt or sugar in water. However, as pressure and temperature decrease, gases become less good at being dissolved - they become less soluble. This causes some of the dissolved gas to be converted to normal carbon dioxide gas, which bubbles through the liquid.
How do modders with limited resources seem to do things that AAA budget developers can't?
This question has been asked a lot lately though in reponse more to battlefront than GTA, please search first before posting in the future. The answer boils down to: those developers could make graphics like that if it made financial sense, but it doesnt, because they need to appeal to as broad an audience as possible by making the game playable on as many mid-range computers as possible, rather than catering to the relatively few people who have high end machines capable of displaying such graphics.
How or where in the evolutionary process did the separation happen between warm and cold blooded animals? What mechanism does it involve?
A key mechanism is going from a three-chambered heart to a four-chambered heart. In a three-chambered heart, one side receives freshly oxygenated blood from the lungs, the other deoxygenated blood from the body. In the third chamber the two are mixed together and pumped into the rest of the body. With a fourth chamber, low-pressure circulation to the lungs is separated from high-pressure pumping to the rest of the body. High-pressure pumping is needed to maintain a warm body temperature.
How does freezing an item (like clothes) remove odors?
The odor is caused by bacterial secretions, and freezing the clothes kills some or most of the bacteria. However, with only freezing your clothes you're left with bacterial carcasses throughout your clothes which is pretty gross IMO. Wear the skin of your enemies, I guess.
How do live closed captions work?
If you're talking about on TV it isn't *actually* live. There is still a delay, but yet I would assume someone is still typing fairly quickly, or they are using a damn good translation service.Yup. They are called stenographers. They use special keyboards that have a different format than a standard keyboard. You can notice a couple second delay on the captioning. The person says something and the captions come up a couple seconds after. Certified stenographers can type 200-250 words per minute, some can do 300> Is there someone there just furiously typing away for live news or events? Pretty much. Like court stenographers they can use special keyboards designed for faster typing, or they can use speech recognition software.
Why Do Fish Schools Form Bait Balls?
"Bait fish" are small and can't swim very fast compared to predators such as dolphins, sailfish, etc. Alone and away from the school, they are easily picked off. In a tight ball, the shimmering and flash of the scales, as they move back and forth makes it hard to focus on an individual fish. Each fish tries to get away from the predator by moving towards the center of the school. _URL_0_ Watch that, and see how the bait ball moves as a single dynamic unit to evade the attack of the sailfish.
Why security screws are used in restrooms?
Bathrooms are an extremely common location for vandalism. Graffitti, cutting/scraping/gouging/burning, and general destruction is common. I'm sure that's no surprise to anyone who has ever used public bathrooms. There are people out there that would remove a door, or stall wall, just for a laugh. Everyone else is no inconvenienced, not to mention, the cost of replacement. There are also people that would just loosen everything so the next person will make it all fall apart, possibly getting injured in the process . Security screws are a darn good protection against this. Of course, anyone with a few dollars can just buy security bits, but at least they can't just take a dime out of their pocket and get screws out while waiting for nature to run it's course. It gets rid of that impulse for destruction, and requires pre-planning and forethought, something most people who are destroying bathrooms aren't too good at.
Can drinking salt water when dying of dehaydration help you?
It depends on the amount and kind of salt. I imagine you mean salt like from the table or from the sea. A good thing to remember is, "The poison is in the dose."

Blood may also quickly rush to the tissues around those areas, contributing to the tingling feeling.

Mac OS vs Windows hardware utilization
Macbooks are laptops, and they have comparable specs to any other high-end Windows laptop. Are you comparing Macbooks to Windows desktops? Desktops are always more powerful than laptops because they don't have to worry about power usage. To answer you question directly, they both use the hardware pretty similarly. There will be some difference in how they cache data in RAM and how they regulate the CPU frequency , but a Mac won't be faster on lower-end hardware unless there's a third party program running in the background on Windows that isn't running on a Mac .
