Why do shipping companies do residential delivery during common working hours, wasting resources in coming as often as 3 times to my door, instead of having an evening shift delivery? | I spent some time working on a project for UPS. I do not know the precise answer to your question, but to say that UPS examines every detail of every operational cost is almost an understatement. I would guess that the percentage of re-deliveries and the space they take up on a UPS truck is so substantially low so much... |
What does a teeth polishing do? | Oh oh I think I know this one! It's basically hardcore brushing. Porous rock such as pumice is fantastic at roughing up your enamel just enough to smooth things out. Hope this sorta answered it. Source: dentist's son |
helium and making stuff lighter | Because the cost to gain ratio is not worth it. It takes a big volume of helium to make a small weight take off the ground . It is not practical to reserve room in planes or rockets for helium, and the gain would be minimal. To give you an idea, a boeing 737 is a commercial plane with a volume of roughly 400m³ , depend... |
Why do soldiers in corrupt dictatorships support those in charge? | The military in those areas is often supportive of the regime because the military either *is* the regime, or receives significant support from it. This is a big part of North Korea, for instance -- the military gets a bit better food, money, etc. than the average personWell lets look at this from a soldiers view. "Me ... |
Different roles/parts in the Music Industry? | First: some definitions. Artists - the musicians themselves. These people actually play the instruments.

How Do Those "Free Cruise Giveaway" companies work? | Because they aren't giving you them for free. They are usually trying to get you on to the boat where you are their hostages for what ever shit pitch they have planned, if they sell even to 10% of those "qualified" people they 've made a profit, even when taking the other 90% into account, and those pitches aren't opti... |
Radius of Convergence. What the heck is it? | I'm assuming that you've learnt what a power series is and what convergence means. A given power series can either converge or not converge. If you have some parameter in your series, you can state that the series will converge only for certain values of that parameter. This is the radius of convergence. Example: Sum o... |
Why are we so irritated when we’re not in on the joke? | Ok based on conversation I've had with people smarter than me: all comedy is derived of fear. The act of laughter is a physical response to us feeling relief, as in thinking that we were about to die, then making a noise that celibrates the fact we survived.So assuming that's true, my THEORY would be when we see people... |
Why is '10 items or Less' wrong? | "Fewer" is for things you can count, "less" is for things you can't count. Obviously, items at a grocery store is something that can be counted, so "fewer" should be used. The other rule is "fewer" for plural nouns, "less" for singular nouns. Again, "items" is plural and should use "fewer". Then again, this is a relati... |
Why are Mountain Dew and Doritos associated with gamer culture? | Long before Red Bull and the other energy drinks, Mountain Dew was well-known as the soft drink with the highest caffeine concentration . As for the Doritos, I don't know.I think the meme probably predates it a bit , but tying the two together with the gamer identity can probably be blamed at least partially on the [Do... |
Could Greece be "forced out" of the Euro? and if so is this good or bad for the Euro in the short and long term? | This is a very basic response, but the euro is a currency that is used by the mojarity of europe. Since many countries are small, people travel around a lot. Every time you went into a country, you would have to change currenecy They made the euro to have one currency so that it would be easy.

Whe does a music artist's early work always have more legacy and popularity than their later work? | Often it is because the artists becomes more experimental, making music that less people appreciate. The early work of an artist also often carries more nostalgia for people. Queen is a good example of this. Their early work is stuff that appeals to a wide audience with subject and aesthetic. Their later work was becom... |
Why do you sometimes wake up early feeling really hungry the day after having eaten well including a big hearty evening meal? | When you eat a big meal your stomach swells. Hours later, when your stomach empties, you feel “hunger pangs” as your stomach shrinks. Your stomach “growls” as it shrinks in size and pushes out air. We associate hunger pangs with being hungry, even if we do not crave food. “My stomach is shrinking, I must be hungry.” I’... |
Why do I look decent in the preview of my self-facing camera, but like I'm sick and dying in the final flipped version? | Faces aren't perfectly symmetrical. You get used to seeing a flipped version in the mirror, so when you see the normal version all the asymmetries stand out to you. I guess symmetry would be associated with health subconsciously.[This] is a fairly interesting video that could answer your question about 3 minutes in .It... |
How does the red light in a darkroom not spoil film? | The chemical reaction requires the input of a certain energy to take place, and photons of light are the source of that energy in photographic film. Photons of blue light have more energy than photons of red light, so if the energy required for the reaction to take place is more than the energy in a photon of red light... |
Why can a coaxial cable carry hundreds of HD TV channels but a PC display cable can barely handle high resolutions? | Your DisplayPort cable actually has more total bandwidth, as much as 17 GHz. The difference is that this data is sent relatively *uncompressed,* that is, close to every pixel of every frame is transmitted. By contrast, cable TV is sent highly compressed, avoiding sending redundant data but requiring more compute power ... |
Why don't school years end with the calendar year? | In Australia they do. School in Australia goes from January to December. I imagine this is probably quite common with schools in the Southern Hemisphere. In the Northern Hemisphere it doesn't work like this before schooling started when most people were farmers and so they needed their children to help work the farms. ... |
This video of 32 metronomes all synchronising | You see that surface they are on? That's not a fixed surface but it is allowed to vary in its swing, just like the metronomes, albeit less obviously. Now, suppose all pendulums are static except for one, the surface will be pulled toward the same direction of swing as that one pendulum because as the pendulum swings up... |
Why do autistic people not like to look people in the eye? | I'm pretty firmly on the spectrum, but high functioning. I do IT for a living, and among other things am the primary PC tech for about 800 people, so lots of social interactions in my daily routine. The thing is though, that unless you've part of my inner circle of friends, my social interactions with you are mostly me... |
Why can't you 'die' in your dreams? | You can die in your dreams. I've had several dreams where I died. Once I had a dream I was in a building and the building blew up. I remember everything went pitch black and I was looking for a light. The light never came. And as I was looking around in void of blackness, I was exhaling all of my air in my body; which ... |
In movies when people point guns at each other is there actually a chance that if you shoot first the other person will shoot as he/she dies? | guns are only instantly lethal if they hit very specific parts of the body. Sure you'd have a very hard time shooting someone after being shot just about anywhere, but it's possible. |
How does the house have the advantage in Blackjack? If I followed their rule of hitting on anything less than 17, shouldn't I have the same advantage? | Because the player has to go first. You have a chance of busting before the dealer even shows their second card , making it less likely for you to consistently winIf the you bust, you lose, whether the house busts or not. This gives the house a significant edge. |
Why does it sometimes feel difficult to draw breath when there is a lot of wind, like in the backseat of a car with the windows down? | Via [Bernoulli's principle], pressure is inversely proporational to velocity. Turn your head at a right angle to the wind. You will have a hard time breathing because the velocity of the wind creates a pressure drop in front of your nose and mouth. And you will have to suck harder to get air into your lungs. It's a lot... |
How does fire spread? | The actual flame is the byproduct of a chemical reaction where something combustible, heated to a certain point, will react with oxygen in the air, to produce more heat. This heat then heats up things around it, and providing that they can burn, and that the heat from the flame is enough to make them react, they will a... |
How do creationists explain how we see stars that are to far away that we wouldn't be able to see if the world was only 6000 years old? | God did it. That or we miscalculated the distance away they areBecause God. At the end of the day you can never win that kind of argument with logic because with faith God can bridge nay logical gapJimmyMac80's answer is correct. However, keep in mind that creationism is not a scientific theory, so "how do you explain ... |
Why do older movies have the credits at the beginning and newer ones at the end? | Part of the reason is that many, many more people are now credited on movies. A credit scroll longer than 10 minutes would test the patience of audiences. So now the main actors and key crew members might be credited at the beginning, leaving the full list until the end.Part of it is that many more people are credited,... |
What exactly is the mechanism behind the corruption of the "Nintendo" graphic on older Game Boy systems when the cartridge connection was poor? | Basically, the image is transmitted by bits of code that if there's not a proper electrical connection for the game cartrigdge, some bits make it and some don't. Leaving gaps/corruptions in the data stream to show the image. Newer consoles have a bios, but still read data similarly from disks, memory, or other methods. |
Why does the public not call for re-elections of officials who screw up or go against the interests of those who elected them in the first place? | > Why do the voters not simply call for a re-election when they realise that things aren’t working out for the best? In the U.S., there is no recall at the federal level. Elected officials have to be impeached. Unlike a recall, this is a formal process which originates in the legislature , as opposed to originating wit... |
If you're killed in war, what happens to your weapon? Refurbished? Recycled? Destroyed? Hand-Me-Down? | If the weapon is recovered it is supposed to go back to the armory to see if it is still serviceable, repaired and cleaned. If the weapon is damaged it is stripped for parts. If it is still in good shape it is stored for reissueI can only guess-timate from when I was in the US military. They would be reused. Each weapo... |
Why are the ~5 million non-Jewish people exterminated by the Nazis often not considered part of The Holocaust and why don't we have a name for what happened to them? | Well, like the quote you put pointed out - they are considered part of the Holocaust. As to why the focus in mainly on the Jews, that's because the focus *was* mainly on the Jews. They were the target of most of the Nazi propaganda, and they were the group that the Nazis were most vocal and perhaps most consistent abou... |
Why do people think the "mind-body problem" hasn't been solved yet? | > Are people just moving the goalposts and is there a desire to reject the notion that you're nothing more than neurons reacting to stimuli? Pretty much. We have a sense that mind is in some qualitative way distinct from body, and that we are in some sense greater than the sum of our parts. I agree with you that that s... |
How difficult would it be to setup and maintain something like _URL_0_? | Implementing it would be extremely simple, and URL shorteners are often used as a beginner project in courses. At the simplest level it's an application with only three routes/endpoints: 1. GET The front page, where users can submit URLs.2. POST to something that accepts a URL, generates an ID for it, and saves it in t... |
Why does looking up at a light encourage your sneeze? | It doesn't for everybody, just for the small percentage of the population with [Photic Sneeze Reflex]. The "sun sneeze" condition isn't very well understood, since it's mostly nothing more than an occasional nuisance that affects a small number of the population. I have it, my Mother has it and one of my two daughters ... |
What/where/why is there pain in being really hungry? | Pretty much. All pain is in your mind. It is an unpleasant feeling designed to make you remedy the situation by eating. |
Why can we better perceive objects in low-light conditions from our peripherals than direct line-of-sight? | The eye contains two main types of perceptive devices - Cones - The ones that are less sensitive to basic light, and allow us to perceive color in situations where light is plentiful. Rods - Devices that are meant to simply detect basic light and don't care about its color, that are overall more sensitive and mostly de... |
how my stomach growls. | You know how when the toothpaste tube is almost empty, you can get more out by putting your fingers at the bottom and squeezing it up towards the top? You entire digestive system is doing something similar pretty much all the time, so that it can move food through your body. It's called peristalsis. At certain times, l... |
What does it mean when the POTUS signs a bill? Can POTUS just decide not to? | It means the President approves of the bill. When he rejects it, it's called a veto. When that happens, Congress votes on the bill again to determine if they can override this veto. |
assuming we can make it work, what will the first generation of quantum computers be able to do that we cant do now? | A quantum computer will be able to solve problems like cracking the password on your computer much faster than a regular computer. Password crack software requires generating all possible passwords, and testing them to see if they work. If your password is say a 20 digit decimal number that requires 10^20 passwords to ... |
Google Drive terms of service | Any creative work you make - a song, an essay, a social media post- is automatically copyrighted and owned by you. That means that any business that wants to do something with your content needs a license from you to use the content. What Google's terms of use say is that you retain ownership of the content, but give G... |
why are some gymnastic/flexibility moves so easy as a kid but really hard as an adult? | Ossification, that is the conversion of the more flexible cartilage with bone, does not end until adulthood . At the same time, ligaments and muscles that keep joint movement in check grow stronger and less permissible of extreme movement. The latter can somewhat be countered with exercising and training , however not ... |
Does the rotation of the earth affect airplane flight time in any way? | Yes, but maybe not in the way you're asking. Planes travel through the air, which moves along with the rotation of the Earth, so relatively speaking, it's not much different than asking if a car is affected by the rotation of the Earth. With that said, the rotation of the Earth does affect wind currents, which is why i... |
Under what circumstances are constitutional rights invalidated within the continental US boarder? | It happens all the time. Prisoners and criminals lose their Constitutional rights. As do members of the military. In many cases, minors do not have the same rights as adults. Most LEOs operate under warrants or probable cause -- which is a judicially recognized and Constitutionally acceptable method for suspending some... |
Why does the melanin in our eyes not react to sun exposure the same as the melanin in our skin (i.e. darken our eyes in the summer)? | Alright, I have a definitive answer. There is a pretty simple difference between cutaneous melanocytes and uveal melanocytes . The melanocytes in your skin are stimulated to begin melanogenisis by hormones called melanotropins. The primary melanotropin that mediates your skins UV response is alpha-MSH. The melanocytes ... |
the 9 realms and the marvel universe | See, this is what happens when you don't make an effort to get everyone on the same page when you're world-building. The best you can really do is "just go with it." According to my understanding of norse mythology, the 9 realms could be considered like alternate dimensions, or they could be considered as just other wo... |
Why/How were so many isolated islands inhabited since B.C.? | It's not just isolated islands - [Australia was peopled] by at least 40,000 BC. *Homo sapiens sapiens* have been around for 200,000 years, and are the only *Homo* species to make it to every continent. We're a very prolific and innovated species, and 200,000 years is a very, very long time to find new places to live. I... |
Why don't the other Islamic countries support Palestine? | Because it'll put them in the crosshairs of Israel and all of its allies. Even if they secured a position for Palestine without getting the shit kicked out of them in sanctions or more direct military action, what benefit would they get from it? Beneficial relations with a new state that's yet to prove itself in any wa... |
How much of our perception of attractiveness is determined by the culture we live in (media, fashion, etc.) and how much is biologically engrained? | A lot of our standards for beauty are based on characteristics that reflect general health, and in women, fitness for childbirth.

If the current FBI investigation indicates the results of the US election were tampered with by a foreign nation, what happens? | OK, first of all, let's be clear. There is no evidence or suspicion that the voters did not decide this election. The election apparatus of the US is very complex and every state has it's own. A foreign power would literally need to hack 50 elections to hack the American system. However, you can hack an election withou... |
How do organized crime leaders still hold their power while in prison? | A leader rules only because his followers allow it.

If one or more of these blood vessels in your neck is cut your brain quickly becomes... |
can someone explain why one of the world's largest social media apps, vine, would choose to shut down? | Vine didn't choose to shutdown. Vine's owner, Twitter, chose to shut it down, presumably because it wasn't making any money and cost too much to keep running, when Twitter itself is having trouble determining a revenue strategy.Being large is not intrinsically good. Being social media is not a guarantee of being profit... |

Why can't we make gold in a lab? | _URL_0_ We can but it takes a particle accelerator or a nuclear reactor, produces very small quantities & costs far more than digging gold out of the ground. To understand why, let's look at what an atom is - it's a bundle of protons, neutrons & electrons. The number of protons in an atom defines it as being a particul... |
How can we communicate with man made objects on far away planets? | There's a super awesome space network! With giant satellite dishes that can be aimed and space probe repeaters. _URL_1_ _URL_0_ |
Why does "snoring" occur? | Put your lips together loosely and make the "Pfft" sound. To snore is to accidentally do that with your nasal passageway while you sleep. Pretty much any animal can snore if it is trying to sleep when it has stopped-up nasal passageways. Some animals snore more than others based on the anatomy inside their faces The on... |
How do VR headsets work? | Let's go bit by bit. First and foremost is the eyes, crucial to any vr experience. VR headsets display two slightly different pictures to each eye. Your brain is designed to calculate distance of an object by how different the vision in each eye is, so the VR headset can make you think a pretend object is far away or r... |
how do astronomers know the exact position of every planet at any time they want? | Astronomers over long periods of time have visually pinpointed Mars' position in the sky. Using lots of these observations and our knowledge about gravity and planetary orbits, they've been able to use math equations to describe Mars' orbit around the sun. There is an equation that describes Mars' position relative to ... |
When someone is experiencing an episode of sleep paralysis, how or what causes/allows them to finally "snap" out of it if they have no control up until that point? | Everyone experiences sleep paralysis. What you are talking about is when people are aware of it. Most of the time you are not aware of it happening. It is what prevents you from acting out what you are doing in your dream. Sometimes people can awaken just enough to become aware of the fact that they are paralyzed while... |
Why are many big container and cruise ships registered in certain countries like Panama or The Bahamas but never ever go or operate there. | It is called a "port of convenience". The biggest reason is cost. It's just cheaper to register from Bahamas. Add to that there are rules such as the US apparently requiring a certain percentage of the crew to be US citizens, which drives up crewing costs, and you have many levels of savings. I think that the ships are... |
What role, if any, does genetics play in determining the overall look and shape of the female vulva? | As much as it does in the look and shape of any other part of the body i.e. significant. |
What happens when you "double bounce" somebody on a trampoline? | When the first person jumps they begin their upward momentum when they are still in contact with the trampoline surface but with upward momentum the second person jumps down. This action will apply tension to the trampoline surface effectively pushing all other areas of the trampoline upward which will propel the first... |
- The roll(s) of oxygen and electricity in the human brain. | Oxygen does the same thing in the brain as everywhere else: provide an electron dump at the end of the electron transport chain that makes most of our cellular energy. Electricity is kind of a misnomer for the impulses which power neural communication. What is actually happening is more like a wave of charged particles... |
The city I live in is below sea level. How come it's not underwater? | because there's either a manmade seawall made of non permeable materials or a natural bedrock that prevents seawater from flowing to you.Is the land around your city above sea level? |
Why is Hibernation not yet possible? Will it ever be? | while we cannot suspend or, more importantly, wake complex lifeforms. we also do not have any idea how to maintain our "volatile" memory, which is to say, our memories go dark when you turn off the power. So reanimating a body isnt much use if you are brain dead. If you store a brains information, and reload it to the ... |
What is this 3rd pole and what is it for? (Biology, Mitosis, Gif) | It looks like its membrane/wall being compressed when its formed to look like a football. The ends are stiff but the middle provides more give. After the split, tennis ball squish all around. |
Why is it that a liquid that is hot will cool if you whisk it a lot but a cold liquid will heat if you whisk it a lot? | Okay, so “heat” is molecular movement. If something is really hot, the molecules in that thing are moving really fast. In liquids, heat is the movement of molecules and in solids it’s the buzzing around of molecules. So, imagine you have a spoon at room temperature and a liquid that is boiling. The molecules in the liq... |
Before the invention of electronic tuners, how did they know a guitar / piano / violin, etc. was "in-tune"? | You would tune the first string to a known source, like a tuning fork. Then use a node in the first string to tune the second. Second to the third. Third to the fourth. Edit: damn autocorrectSome people have good ears. Some have very good ears. Orchestral players still tune to one instrument by ear. You can tune a guit... |
What qualities make a face attractive and why do they vary among different people? | From what I understand, facial beauty is about symmetry, not proportion or a set standard. Which is why you can have someone with exaggerated features, like Adrien Brody, still considered attractive. Of course, there are also gendered desirable features. Big round eyes for women, like Tyra Banks and strong jawlines for... |
How do you program graphene? | Since it's no longer April Fool's Day, I'm going to go out on a limb and assume this is a real question. Graphene is just a material. In order to make a CPU you could actually program, you'd have to make transistors out of it just as you have to make transistors out of silicon today. Those transistors would be used to ... |
What do I eat, take(pills), or snort to be healthy and have sufficient energy? | You're reading tons of contradicting material because there's actually tons of contradicting material. The only simple answer that everyone actually agrees on is "eat a variety of non-junk foods while also exercising enough". Fortunately, the human body is pretty adaptable. So 99% of people will be perfectly healthy if... |
what is multiple system atrophy (msa)? | Simply put: the neurons in his brain are slowly getting damaged which is causing him some issues. You can think of it as another version of Parkisons as it expresses similar-ish symptoms but does not respond to the same treatment. |
Why is the contents of iron supplements so much higher than the recommended daily allowance? | Iron supplementation may need to be higher than the general populations requirements if someone needs iron stores replacing if they require more iron due to ongoing medical problems. Additionally not all iron may get absorbed anyway .what it needs and what it can handle are 2 different values. you only need about ~10 m... |
Where does the power lie in the European Union? | Think of the EU like the US federal government and the countries as states. Now make the states each powerful enough to say no to the govt but not necessarily to all the other states if they work together. Some countries like each other, some don't. Some will work together and others will block things out of spite.u/an... |
Why do our nipples get hard when it's cold outside and/or when we get goosebumps/the chills? | In both men and women, there are some muscle cells underneath the nipple that are under autonomous control . These contract under various stimuli and cause the nipple to become erect. Getting goosebumps on the other hand, is a vestigial response from the days we used to be covered in fur. Tiny muscles at the base of ea... |
How do field drug tests return so many false positives? | Field drug tests are designed to be very cheap, and very easy for an amateur to use. Therefore they are not very *specific* -- that is, they just test whether the mystery substance reacts with one or two chemicals in a specific way. This makes it very likely that some *other* substance would also react in the same way.... |
how windmills convert the spinning of the blades into electricity | The blades turn a magnet in a coil of wire, inducing a voltage in the wires. This causes an electric current to flowElectric current is created in a wire when a magnetic field is moved relative to the wire . An efficient way of doing this is by spinning a permanent magnet relative to a coil of wire. The spinning can be... |
Does light travel get interrupted by lights travelling from the side? i.e. We see a star far away, but there is another star with light travelling that intersects the path, what happens? | Nothing happens, the two "beams" of light go through each other without affecting each other. Otherwise you wouldn't be able to see very many stars!', "Right now, you're probably reading this page from a glowing light source . There's probably a light fixture on the ceiling that's sending light down into the room, inte... |
how raising minimum wage would not simply spur inflation to create a "new" system congruent with what we already have | Nope. You're right.The only thing that is going to happen is an employers fixed and variable costs will go up. This will either make his product increase in price, or decrease the amount of labor he hires.All these people think is "Hurr durr more money for me" |
If two people had to repopulate the world, after how many generations would serious inbreeding deformities arise? Would the problem worsen into perpetuity? | Short answer is that it depends, and serious deformities may or may not ever actually arise. The thing is that if the initial two had "perfect" genomes with no mutations corresponding to serious defects, there is no reason that their breeding would necessarily give rise to a population with those defects. If they aren'... |
In the U.S. how can something become legal on the state level if it is not legal on the federal level? | The city/county/state law enforcement officers are under no obligation to enforce the federal laws. If the state says it's legal, the only way to get busted is for federal agents to to it themselves.The fed and any state in the union are separate sovereigns. Same thing goes for double jeopardy. You can be acquitted at ... |
Why is it when you're in a fighting situation in a dream does it feel like so much effort to swing a punch? | When you are asleep, the commands from your head to your limbs are blocked. As such that while you can dream that you are going to run, you don't get the muscle feedback that you are running. As such your body in your dream cannot move while trying to run. |
How did a shaved head become synonymous with the white power movement? Why are they called skinheads? | "Skinheads" is a subculture originating in Britain in the late 60s, it resulted from a split in the "mods" subculture and was formed from the more violence-prone "hard mods" portion of the subculture where the fashion was for guys to have shorter hair and a working-class style. These "hard mods" had very short hair res... |
Why do YouTube videos (and others) have to re-buffer what has already loaded when you skip to a different section of the video? | The load bar is now entirely full of shit, ignore it completelyYouTube used to pre-load entire videos, but that can out a load on their servers. So instead, they changed it to only preload segments at a time, which saves them millions of dollars a yearBecause of DASH playback. You can download YoutubeCeenter and disabl... |
How does exchange rate between currencies change? | Exchange rates are quite complex and not very predictable . It changes based on many factors. Here are two major ones: *Demand for that currency*: If more people want the currency, it'll become worth more relative to other currencies. Banks and other providers will raise the exchange prices. This is why governments enc... |
Why don't we (United States) attempt to rescue journalists/aid workers who are captured overseas by terrorist groups? | 1. It has been attempted in the past, and some of these attempts have been successful. 2. In some instances, the group holding them is judged to be relatively unlikely to execute them and it's decided a rescue attempt would be more dangerous for the hostage than negotiations. 3. Oftentimes it is very difficult to know ... |
Why does sunburn feel warm to the touch and hurt so bad when exposed to water like when taking a shower? | When something is damaged the body attempts to heal it. Part of this healing process is the processof inflammation. This process entails lots of components, such as the signalling of cells and proteins to the site for healing. It also causes dilation of the blood vessels near the skin which in turn allows for more bloo... |
Why do people get sick when the seasons change | There are two main causes: 1. **Allergens**. In Spring, for example, flowers begin to release pollen. Lots of people are allergic to these sorts of substances , so they have a reaction. They don't actually have 'the flu', but the symptoms often look the same. 2. **Environments**. In winter, for example, you spend a lot... |
I understand that all life on earth comes from a single cell, how did that single cell come to exist? | Right now, we don't know for sure, but there are some hypotheses. Organic molecules like sugars and amino acids form from non-living chemical reactions, so we know that Earth before life had a lot of these molecules. Then the question is, what kind of environment would bring all those molecules together best? * Pools o... |
Why do companies say it will take 7-10 days to unsubscribe you from an email distribution? | There isn't a reason. A database query/edit shouldn't take more than a few hours, at *most* and for an extremely heavily taxed database. A relatively unused database , the query/edit should take a few seconds. Usually any place that says "7-10 days" is lying to you, and they won't actually unsubscribe you. I 've worked... |
Why is the color pink synonymously feminine? | I forget why it switched, but it used to be opposite: blue for girls, pink for boys. Reason behind this was because boys were seen as young warriors, and red was the color of warriors. Pink was like a lesser version of red. And blue was just a softer more comfortable color, making it good for girls.It wasn't always. Ou... |
How do the Mars rovers take selfies? | I would assume it involves a process of taking several different shots from different angles, and then compiling them in such a way as to edit out the arm holding the camera. |
Where does the silent P come from (e.g., pneumonia)? | Pneumonia, psychic and pterodactyl all come from ancient Greek. Why the p becomes silent I don't know. Also it's important to remember that for most of human history only a very few people were taught to read and write, how 'tricky' it is to spell something is relative. |
From a business POV, why would McDonalds only give out 20 packets of Szechuan sauce and at limited locations only? | Good marketing that takes advantage of a current trend with low risk. Why only limited locations? Because they literally can only do that or nothing, they can't release the product more broadly because their supply chain for large production is MASSIVE and *SLOW*. Like, I don't think you have an idea of how massively c... |
Boilers. How does one operate? What is their purpose? | Boilers use some sort of fuel to boil water to produce steam. That steam can be used for heating buildings, or to turn turbine-generator sets to make electricity. Operators control the fuel, boiler pressure, boiler level, and safety systems, since at high temperature and pressure, steam can cause serious damage. |
What exactly caused the huge cultural change in the late 60s? | Specific events? Not really. I mean, the civil rights movement had a lot to do with it, but that was a long time coming. Social change is one of those things that is always happening. Occasionally there will be big events that cause rapid change, but those are less common, and I would argue less influential, than simpl... |
