Each merchant has to d... |
Fuels? What does it take to create gasoline, diesel, kerosene, etc and how do they differ? | Basically they all start from the oil we pump out of the ground.All of these things are inside that oil. We then heat the oil in a large tube that has many different levels. As the oil heats up all the different parts become a gas at different temperatures and they settle in the level where the temperature is cool enou... |
The top used Internet Browsers and how they're different. | As you may know, internet pages are written with HTML and various other languages. A nice analogy is to consider a web page as a museum.

Their internal plumbing is different, even when you pull them apart and you notice strong similarities, you also noti... |
Why do creators keep their upcoming projects/products secret until release? | One of the aspects that you may not have considered is that a huge number of projects that people work on *never get released*.

Monkeys reacting to Magic tricks, are they really understanding what is happening? Or does it only look that way? | If they see ball "go inside" a palm and then disappear I bet they understand it well.

what are spectral lines and how do we use them to determine what light has passed? | If you direct light through a prism, you can spread it out and look at all the different frequencies it's composed of. If you look very closely, you'll notice that certain frequencies are missing . That means that somewhere between when this light was emitted, and when you looked at it, that particular frequency was ab... |
How do fish survive long periods of time out of the water without suffocating? | Fish die on land not because they cannot get oxygen out of air, but because their gills are designed to work in water. This means that they dry out relatively quickly and when that happens their gills start to tear and bleed and stop working. At this point they stop being able to breath and suffocate. There are also ma... |
Why is glass clear? | First let's look at a simplified view on what makes something to appear to have colour. Visible light hits some object, one of two things can happen : the light gets absorbed or it passes without being hassled. Why would light of certain wavelengths be absorbed? Electrons in the atoms have certain energy levels, and ab... |
Should i put wet hand-washed dishes straight to the cupboard without drying them? | your question should probably be flaired as biology. If you stack wet plates, the moisture will never get a chance to dry out. In the ideal world, your clean plates have no bacteria, food residue or stuff in the water.

Why are oats "Steel Cut" Why not aluminum or titanium cut? Or hand cut? | "Steel-cut" is more about result than the process.

how can those car re-map boxes improve both power AND fuel efficiency at the same time? | Increasing the pressure in the cylinders will lead to a general increase in fuel efficiency. The theoretical fuel efficiency is 1-1/e^ k is ~ 1.4 for air, and e is the compression ratio. So the higher the pressure the better the efficiency. More pressure means more power as well. So theoreticall it is possible. The pro... |
The difference between fur and hair. | Plenty of animals have hair rather than fur - dogs and horses come to mind right away. Hair is thicker, individual fibers, provides little insulation - but usually some water protection, and while not part of the definition, can be easily combed, cut, and groomed. Fur is far more dense and finer. It provides great heat... |
why is it now code to install outlets upside down? | If a conductive object falls accidentally across the main two prongs of a "right side up" plug that isn't completely flush against the outlet, it will close the circuit. If it's your finger you get shocked. If it's metal there could be a spark. If there's a spark there could be a fire. Building codes are designed to pr... |
Why are click-bait, buzzfeedy titles so effective? | Much the same as any other marketing. Clever people study what works, and hone it until it works better.

Edit: ... |

Stopping slavery wouldn't sudd... |
If new stars are born from the remnants of old stars, are the stars gradually getting smaller? | It's not that gradual. Pop III stars were 1000 times bigger than the stars we call "main sequence". Without heavy elements in the dust clouds around them their cooling was less efficient. NASA has a satellite called WMAP that's looking for data to try and understand these processes betterNo, but it does mean they have ... |
Why do radio stations always give away money, and where does this money come from? | You know those annoying ads for hair removal that they play every six minutes? The hair removal company pays the radio station for that. This is where the money comes from. Oh, and the hair removal companies get it from people who think their body hair must be removed at great expense. Edit: and the people think their ... |
Why do damaged joints hurt whenever it rains? | I believe it is because of the pressure change that occurs when the weather changes, but I'm not an expert by any means! |
I saw a post earlier on r/gifs of a multi-car pile up on a snowy highway. Does insurance cover damage like this, and how would they determine whose insurance to use/whose more at fault? | Yes insurance does cover stuff like that, and it's usually a huge mess. Generally you pay the guy you hit, the guy who hits you pays you, and so on and so on. It turns into a pile of insurance companies trying to hash out with each other who owes what after all the claims are paid. |
What permits do you have to get to drive a police car or dress as a police officer for a 'prank' video? | _URL_0_ > Dressing up as a police officer in costume, or pretending to be a police officer for the purpose of play or a harmless prank toward an acquaintance is generally not considered a crime, provided that those involved recognize the imposter is not a real police officer, and the imposter is not trying to deceive t... |
Why does TV make a crackling sound while turned off? | I would guess thermal expansion for the led tv. It takes a while for things to cool down. Also add in the fact it is usually cooler at night.

When did time start being recorded? Why does it start with Jesus' birth day? | It doesn't. There are, and have been, many different calendars. Many are older than the calendar which starts at year 1 with the birth of Jesus. Human civilisations that had calendars date back thousands of years before the birth of Jesus. There are calendars in use in today's world that don't use that event. |
Why do the LHC need to be so big? Would we get better "results" if it were the size of Australia? | As well as accelerating the beam up to really high speeds, it needs to bend the beam around into a circle. The tighter the circle, the more energy it takes to steer the beam. A bigger circle lets us control a more powerful beam with the available magnets, and produce higher-energy collisions than if we had a smaller ci... |
Why do websites have to be taken down for maintenance? | Well, It can be a lot of things, but here are a few I know off . 1. It could be a major redesign of the website, and if you just "push the next code in" you will be putting code on your server that depends on other things, which might not have been submitted yet and you don't want that. 2. It could be a hardware proble... |
How are Chinese companies on eBay/Amazon able to sell cables and such for 1.50 shipped to the USA? | ManiacalShen may be on to something, but it's not all a marketing gimmick by any means. It is actually quite logical, if only you have all the pieces that is. First of all, as you pointed out, the quality of the cables are usually "garbage" - it doesn't cost much to make crappy products. Secondly, the exchange rate bet... |
Are dogs aware of differences in their breeds? | I don't think they do. It's kind of like if we lived in a non judgemental non racist world. Dogs don't care if one is overweight or a purebred. They will try to play, sniff, and lick them either way. On a small note, I believe they do act differently around dogs that are older. Every time I see an old dog walk around o... |
What happens anatomically when a voice changes during puberty? | The vocal folds grow and thicken due to the presence of androgens. For most males, there are more androgens present which causes the vocal tone to deepen. Females typically do not have as many androgens present thus, only have a slight alteration in vocal tone. |
Why is putting your hands up and showing your palms the universal sign of "I surrender", and why is it instinctual? | It shows empty hands; no weapons, no tricks. I'm vulnerable and harmless, don't hurt me. Military salutes, handshakes, etc. all supposedly originate from the same concept.You raise your hands to make it clear that they are empty, and it also leaves your body unprotected as a sign of submission. It cannot be construed a... |
After the initial sleepiness feeling, why do we suddenly feel more alert after a few hours pass your normal sleeping time before you suddenly feel lethargic and sleepy again? | A certain sleep writer suggests it's because there is a metabolitic release timed to coincide with the early part of sleep intended to for the heavy lifting your lymphatic and endocrine systems will do in the early part of sleep. Apparently this is the "second wind" we feel at approximately 10pm, and being asleep at th... |

The meaning behind the popular philosophical phrase, "I think, therefore I am." | You are thinking. If you did not exist in some manner or fashion, you could not think.

They are built up in endurance events such as long dista... |
Why don't gas pumps take cash? | I've seen a few gas stations that do have a cash-accepting machine. It's for models where the individual pumps don't accept money, you have to go to a central automated kiosk to pay. That being said, there's very little incentive for gas stations to want to make the pumps accept cash. Not only would that require someon... |

Some convert from... |
Why isn't chewing tobacco a big thing in countries like USA, England and ? | If you're talking about nicotine gum, it can have help benefits if it helps a smoker quit. If you talk about chewing tobbaco, it destroys your teeth and is linked to mouth / tongue cancer. As to why it isn't popular ? It's less addictive than a cigarette , it isn't glorified by movies, it wasn't advertised in one word,... |
Why Are Farm Subsidies Necessary? | The original intent was to smooth out supply, since agriculture is so important to society. Farming is a business where one bad year, or a string of bad years, could put you out of business. Also, a business where the end price of the product you produce could vary wildly. So farming is hard! But it's essential, since ... |
If the Earth stopped spinning, would we feel it? | Only if you count us and everything that's not superbly secured underground flung into the cold depths of space "feeling it"It depends how quickly it stopped spinning, and where you are on Earth.

Why does it hurt to pee with an erection? | Uh, it does? Last time I did it it wasn't uncomfortable. I always sit down in that case though, maybe that's why.Because the vascular system around the urethra is constrained and causes the flow out to be restricted, and thus potentially painful or burning. Basically the erection causes the same symptoms of urethral st... |
Why are some chicken mcnuggets shapped like boots, some like fish, and some are round? | **Short**: Because McDonald's Inc thought that those shapes would make them look more "natural" than all being identical lumps. **Long**: Before the get nugget 'd, the chicken used in McNuggets first gets ground up, like beef is for hamburgers. They do this so the flavor and texture is consistent and so they can use cu... |
How are bombs (especially the atomic bomb during the Manhattan project) built safely without worrying about it going off? | uranium and plutonium aren't like gunpowder. It's not like a stray spark would make them explode. They're arguably safer to work with than conventional explosives in most respects. Nuclear material will only actually explode under very specific conditions. Building a machine that actually was able to create the heat an... |
How does a traffic light work and how complex its "computer" is? | it depends, some of these have city/synchronization control, traffic measurement and traffic cameras but ill limit myself to a 'stand alone\' system So > how complex its "computer" is?

Where did the stereotype of black people liking fried chicken come from? | It was a popular dish among slaves, partially because they weren't allowed to keep any animals other than chickens.

But since whites were used to far great... |
What exactly makes different type of animal meat taste different than the other animals? | I am an avid meat eater and in my humble opinion I would think that the difference in taste is related to how the muscle tissue is held together.

Why is necrophilia so much more taboo than murder? | Victorian dogma about fear and revilement of death/respect for the dead that has lingered on. If we lived in a purely rational society, it would probably be possible to donate your body to necrophilia, because you are correct. Burying a dead body is throwing away a full set of valuable organs and tissues. It's a waste ... |
Why are clothes with reflector stripes really bright in the dark when in contact with weak light sources, while they just appear grey in daylight? | The reflector stripes contain many small [Retroreflectors], which reflect light back in the direction of the light source.

Why do most smartphones not have built-in FM receivers? (When they have many other technologies like WiFi, GPS, 4G, etc.) | This is probably for a number of reasons. For one, people care less about FM radio than before. Second, device manufacturers might have a profit motive in selling audio content and other sources of media rather than FM radio. There are some unique complications with FM, though, compared to the other radio technologies ... |
What distinguishes good acting from phenomenal, award-winning acting? | The illusion that no acting is taking place is always a good one.I would say it has to come down to believability and consistency. If an actor/actress can perform, convincingly, different characters in different situations, they are good. Some actors play the same role in every movie they're in, with minor variations; ... |
How does Coca-Cola have a secret formula when all the ingredients are in the nutrition facts? | Its the ratios and the prep that you dont know.

Why are so many more people allergic to gluten or have celiac disease than in the past? Or if this is not the case, how did they live? | I've not seen anything to suggest that more people have celiac disease than in the past. What we do have now are far more gluten-free options for people who do have the disease, and a lot of people who don't have the condition but who seem to think that gluten is inherently bad for them. In the past, someone with celia... |

Why does ice expand instead of contracting? | I think scientists are still trying to figure out exactly why this happens exclusively with water, but in a liquid state, water molecules are allowed to freely flow around each other. When they freeze, though, they form a crystal structure which, by the nature of its shape, takes up more room. In other substances that ... |
Why does cracking your joints get easier if you do it a lot? | My mom used to be a medical researcher. From what she explained to me, the most negative side effect is that when you pop any joint, you overextend the connective tissue surrounding the joint. Which I guess would eventually make it easier to pop your joints the more you do it. This overextension wouldn't cause to many ... |
Why do our voices get higher pitch when something exciting happens? | Increased airflow, and tightening of the vocal cords themselves. Excitement can be related to many things, but speaking biologically it implies that extra physical capability could be useful - adrenaline, deeper breaths , and tightening of muscles to prepare to spring. |
The Chinese Governments side of the situation in Tibet. | While I would debate your initial premise as a little shaky, i'll try to answer anyway. Governments must often make decisions which they see as the lesser of two evils. The Chinese justification consists mainly of the idea that Tibet is a part of China and should remain such, but I think think if you dug a little deepe... |
How is fetanyl becoming so widely available? | > Where's it coming from? The largest suppliers appear to be in China, shipping both the tools of production and the raw fentanyl to the US and Mexican cartels. |
Why does our vision flash black when we get hit in the head? | When the head gets hit hard, the brain goes into a lapse of shock and trauma.

In order to send a signal, the eyes must send it down t... |
How are data stored/burned into DVDs/CDs, and also how are the information read? | Lasers! Information is read from optical media discs with a laser. The disk reflects the laser or not and that is a 1 or a zero for that particular point. Writeable optical media allow you to use lasers to manipulate the disc in such a way as to burn into them wether a certain spot reflects the laser or not. |
why are a lot of cooked dishes like salmon or meat high on protein if most of the proteins denature at ~40 degree Celsius? | Proteins denature at high temperatures which means their shape changes to the point where they can no longer do their purpose but they still exist as molecules which can be used for nutrition |
how do serrated blades work? What about the serration makes them better than flat edge blades? | The reason a knife is good at all at cutting something is down to pressure. The narrower and sharper an edge, the more pressure it puts on whatever is being cut. The blunter it is, the wider an area the force you're applying is spread so the less pressure there is at the point of the cut. A serrated edge lifts the main... |
- Why does extended exposure to water dry your hands rather than moisturize it? | Osmosis is the diffusion of water. When you overflow your hands or any body parts or almost any tissue/organism with water, the net flow of water will be wherever there is a higher concentration of solute. When you put water on your hands, it flows in because there is more solute like salt in your blood and inside than... |
Why do websites need to ask for your city, country, and state, when they can figure it all out through your zipcode? | That pretty much is a thing of "laziness" : Its much cheaper to put multiple inputs there instead of maintaining a catalogue of all zips mapping to the required information. EDIT: Source: I work in software development', "There are edge cases where they actually *can't* figure out all of those things from your zip code... |
Is Erdogan really that powerful as he is presented in western media? If so, how did he become it? | He's hardly represented in western media in the US. He is an extremist, rather than centrist, politician. While that seems fashionable today, political fashions vary year by year. When warm and fuzzy collaborative politicians become fashionable in a few years, he's going to look like a throwback to the region's dictato... |
Why can't I "unbake" a cake? | There are differences between certain actions . For instance with a cake, you might mix egg and flour, and whatever other ingredients, together.

Its competing against other game developers, and it most likely intends to release more than one game. So it could publish and then leave it and never touch it again, but if his competition then proceeds to publish a game, and delivers a steady stream of conte... |
Why do companies care about the price of their stocks? | A share of stock is literally a small piece of the company.

Also, executives typically own a lot of stock, so it makes them richer. |
the little pi thing on the bottom of every page on reddit | This has been asked before but it is hard to search for. Reddit as a whole has a lot of people visiting the website at any given time. That many people would be too much for just one computer, so there's a special computer that moves each visitor to another computer so each individual computer gets less work. There are... |
How does data corruption work | Computers are incredibly fast and incredibly stupid. They expect their data to be highly ordered.
