how does your brain decide you like/dislike a certain song? What influences that? And why do we all like different songs? | Basically, it comes down to sensing versus perceiving. Generally everyone senses the same things the same way, from vision to taste, excluding those with sensory deprivations . Perceiving is a different story. It's all in your head. We attach meaning to different sensations. Like when you see your SO and get happy if y... |

How is the 3D effect created in movies? | You need a second camera that is filming from a slightly different perspective, just like humans can see in three dimensions because they have two eyes set slightly apart.

Why is sleep so comfortable shortly upon waking(especially when you have work/school/etc)? | When you wake up in the morning, you get something called sleep inertia. It's the groggyness you feel up to two hours after you have woken up. It's a "false" kind of sleepy, which makes you want to stay in bed. This combined with how comfortable your warm, soft bed is, makes it so darn hard to get up. _URL_1_ _URL_0_ e... |
What happens to your body that makes you dizzy when you get up too fast? | When you stand, blood briefly pools in your lower extremities. Your body undergoes what is called vasoconstriction, to equalize the blood pressure pretty quickly, by squeezing blood back up into your body.

What would happen if an asteroid the size of the moon hit the earth? | The asteroid that may have been responsible for the extinction of the dinosaurs had a diameter of about ~~170~~ 10-15 km.

My grandparents live in a small town, where all of the older residents have a land line number that begins with the same three numbers. Why is it the same? | Jesus christ, are you trying to make us feel old, OP? That's how ALL land line phone numbers used to work. If there was less than 10000 lines, they all belonged to the same exchange. You'd get 555-0000, next person got 555-0001, next person got 555-0002. You kids and your cell phones and skype and hoola hoops and pacma... |
Why Nuking a asteroid that is headed for Earth is not a good strategy. | Let's start by assuming that we have the nukes to fracture the asteroid. It may be a long shot, but nukes release a *lot* of energy and asteroids aren't necessarily as solid as a typical rock on earth. The big thing is that the Earth is still being hit. When you break an asteroid into two pieces, the energy of the orig... |
Why are Canada Geese called such instead of Canadian Geese? | Because it's their name, not their nationality. If I live in New York, and my name is Bob France, you wouldn't call me French. |
Did Rob Ford actually help the city of Toronto? | [Here's a good article that goes over the positive outcome for Toronto] tl;dr: While Ford's campaign was based on "stopping the gravy train", he never found one.

Why do basements/cellars tend to attract mold and mildew so much? | A cellar is usually colder then the outside as it is kept dark and surrounded by cold dirt. Humidity is based on not only the amount of water in the air but also the temperature of the air. So when air gets down into the basement and gets cooled down its humidity increases. All life needs water to thrive. Basements wit... |
Is it possible to have more than one type of flu (bacterial or viral) running in your body at the same time? | Just to clarify a little more "Flu" does not just mean illness.

Why do humans express ourselves creatively? | **TL;DR**: *We have intelligence and spare time and a desire to accomplish something and to leave something behind or give something to other people. Being creative uses the first to fill the second and fulfill those desires.* In terms of flair, this isn't so much about culture as it is biology. The first reason is tha... |
When people go outside to take a breath of fresh air, why does that help calm them down? | Going outside firstly removes the trigger and stimulus that's causing the stress - and so they can get out of an emotionally charged situation. Fresh air may also be a change in temperature, so they have a different physical response too, and that may help them breathe deeper, giving the stress hormones a chance to dis... |
I just read the Brian Banks story; Why are women who falsley accuse men of rape hardly ever if at all sent to prison? | If they were proved, in a court of law, beyond a reasonable doubt, to have knowingly and falsely accused someone, they do get sent to prison.There is a difference between a false accusation, an accused raper being found not-guilty, and being criminally liable. It is possible that someone gave false witness that they re... |
How is Yahoo still a top 5 most visited website? | A tremendous number of browsers came with it auto-homepaged in the earlier days of the internet.

A whole lot of older users have it as their home page, so eve... |

If your voice sounds higher than what it sounds like to you, how can you sing the correct pitch? | Practice listening to yourself and *actually* hearing your own voice. Singing in a small, acoustically live room can help. I recommend purchasing some pvc pipe and making a small phone shape so that you can sing into one end and have it projected directly into your ear. I can almost certainly assure you it is not a bio... |
Why are there no Grape flavored Yogurts? | Chobani made a grape yogurt, but I don't think it sold very well. Grape and yogurt doesn't really mix in a way that is large scale marketable to consumers. Yogurt can be kind of sour, mixing that with grape is not a flavor many people can get behind. |

Why is tinfoil (aluminum foil) so heat resistant? | Heat resistent in what way? If you refer to "Why doesn't it melt", simply because it's melting point is incredibly high, much higher than your grill can produce . If you are instead refering to "Why doesn't it get super hot to the touch" then you're building on a wrong premise: it isn't heat resistant at all and does g... |
Why do french fries taste good while they're hot and nasty cold? | Your tongue can detect basic flavours only: sweetness, saltiness, sourness, etc. Most of what we call the sense of taste is actually sense of smell.

Why do I always wake up early after a night of hard drinking? | It also messes with your sleep cycle.

What the Drake and Meek Mill beef was all about. | Meek called Drake out for using a ghost writer . Drake got offended and started a one-sided twitter war while Meek sat back and laughed.

Why do loud noises seem to physically hurt? Is it all in our brain signals? Do deaf people feel pain from them? | Pain is how our body signals to our brain that we're in a situation that's potentially causing us harm, so we're motivated to try to get out of that situation. Loud enough noises can physical damage your ear, and as a result, we've evolved so that somewhere before the threshold of damage to our delicate ear parts, a lo... |
How do carnivores like Tigers and Lions get enough nutrient balance by only eating meat? | One, By eating things like blood, skin, organs, bones, etc. Obviously that animal they ate *contains all vitamins and minerals required for that prey animal to live* so consuming all, or most, of a prey animal will include a wider variety of vitamins and nutrients. Humans can do this too, for example fish liver oil, wh... |

Nowadays most money is digital, what prevents a bank to edit its computer records with another trillion $? | Digital money isn't just a number in a spreadsheet, it's an accounting of where the money came from.

How does electronic currency mining work? | Simplified, with bitcoin, the "coins" are a long chain of solutions to a convoluted math problem. Each coin has to be discovered mathematically by computing out the problem, and it's designed so that each new coin's problem is harder than the one before, and that only a set number of coins will be discovered. After tha... |
why is the Wilhelm scream so overused in movies? | It's an inside joke/running gag. Sound mixing is a very tedious job, so they like to have fun. Like how Pixar movies almost have "A113" in their movies. |
When dieting and losing weight, is there a universal right way? Also do cravings mean something? And other ? | The right way is to utilize more calories than you consume. All diets that succeed do this, all diets that fail, fail to do this. People may be more or less effective at eating less calories, or at burning more, but the equation is always the same. It is possible that combinations of foods make you feel better or worse... |
Why "Gravity" Does Not Exist | Newton said gravity is a mysterious force that affects everything with mass. He didn't know what causes this force but he did create some useful equations. Then Einstein came up with General Relativity. He says that mass bends space-time and that's why things are attracted to each other. For Example, if you put 2 heavy... |
Some genes, increase the likelihood of getting certain diseases (like cancer) why? | It's kind of misleading to think of the gene as being exclusively for cancer-causing purposes. Typically the "cancer genes" people talk about are variations on a gene that codes for sometime useful. Like when people say they have the BRCA1 gene , they don't actually mean they have a genetic sequence in a place where ev... |
What are the primary cost saving mechanisms of single-payer systems? | If you think about what a private insurance business looks like right now and notice that a huge expensive fraction of it provides no actual care, or even actively works to AVOID providing care, you'll start to see how single-payer systems can be more efficient. I'll list some costs associated with private health insur... |
- How Do Solid State Hard Drives Work? | Flash drives work by having individual cells that are left with an electrical charge by depositing extra electrons that is maintained even after power is removed.

Why do floppy disks and SD cards have a mechanical lock switch to block access, when anyone can just flip the switch and access the data inside? | The lock on floppies didn't deny access to the data. It locked out writing over it. It's more a a precaution to keep your data safe from yourself.OP confirmed for 5. The security hole on floppies prevents it from being written to accidentally, not from being read. Same with the SD cards. |

Why does good cellphone service/4G come and go, even in the exact same location. | Could be a number of reasons. Most commonly: 1. That is because cell coverage is a "breathing" network. As more people use the tower the less power an antenna can allocate for you so the coverage shrinks. As people log off or move out the more power an antenna has and the better your service will be. This is especially... |
Distillation as it pertains to alcoholic drinks | Once the liquid that they are making the liquor out of has been fermented, and has alcohol in it, then the alcohol needs to be concentrated.

Are magnets just found or does man make them be what they are? How does this happen? | Both, magnets occur naturally and we can make them. So electrons are like fanbois and ~~neutrons~~ protons are like hot babes. The bois orbit in the friend zone of the babes, never getting too close, never getting too far away either. If a bunch of babes and their bois go to a mall, and there's a sword outlet on one en... |
Why do we cover railway tracks with rocks ? Does it improve the stability when a train goes by ? (due to the vibrations) | Although it doesn't look it, the ballast is pretty solid. It distributes the load from the passing trains, keeps down unwanted vegetation and enables water to drain away. This last one is very important. Where I live, there was some flooding back in May, and parts of the railway line were submerged. The water, having j... |
Why at high speeds on a highway with the window down create s fast pulsating air sound? | Have you ever blown air over the top of a bottle and made that cool "hum" noise? If so, I'm sure you 've noticed, the tone gets higher pitched with a smaller bottle, or with more liquid in it. The same thing is happening in your car, only on a much larger scale, which is why the tone is so low . The window is open, act... |
Why does it take longer to develop professional baseball players than professional football or basketball players? | The average length of a professional baseball player's career is longer than that of an NBA or NFL player, largely because the athletic skills needed don't drop off as dramatically once the player gets into their mid to late 20s. So, since a baseball player has a longer career, they can take longer to develop the skill... |
China's one child policy and their economy | The one child policy was that if you had more than one child you would be fined, and then more heavily taxed. They did not take and kill children.

Is it possible to have any more than 3 spatial dimensions? | There are only 4 dimensions that we can experience . Other dimensions can exist in mathematics at least. The problem is that we cannot properly imagine these dimensions, since our minds cannot truly comprehend/ visualize a fourth spatial dimension. We can sorta represent 4D object in 3D, just like we do with 3D objects... |
Why do things with lower resolutions look bad only after seeing something higher in resolution? | Because the brain is really good at filling in blanks. You're not seeing the picture itself, you're seeing the thing it is a picture of. You don't see a collection of brown and green pixels, you see a tree. It's not until you have something to compare it against that you notice the difference. |
Why do new cars smell the way they do? | because of left over chemicals from the plastics and the leather or faux leather treatments are evaporating into a mostly sealed environmentThat sweet sweet smell is just a bunch of plastic chemicals that are probably as bad as smoking a cigarette. |
I tried to sign up for health insurance through _URL_0_ but I don't make enough money to get subsidized...what do I do? [from Florida] | If you do not make enough money to get subsidized, you may make little enough money to qualify for Medicaid.

If you fall within ... |
how come there is thunder/lightning during storms but during blizzards/snowstorms there is no thunder? | Actually, there is! [See this!] That said, the reason you don't usually hear thunder during snowstorms is because snow actually suppresses the sound! It basically absorbs it, since it's just fluff in the air, drastically reducing the distance it can be heard! While a regular thunderstorm can be heard for miles and mile... |
Power button on a smart phone | I suggest that you read a few button tutorials for embedded systems like arduino or raspberry pi. The processor can read the state of the buttons at any time. So they do this in a loop. When they notice the button is pressed they start a timer and wait for the button to be released. By measuring the time it takes for y... |
Why are most holiday messages depersonalized? | It's so that the card won't be limited to being from a single person or a group. "Wishing you a happy holiday" can come from either your single brother or from both your grandparents. If it said "I wish you a happy holiday," groups and couples wouldn't buy that one, and vice-versa. So the company that makes the cards w... |
Why do people use American Express credit cards? | American Express is a very Customer-Oriented card program. The individuals that actually carry and use the card love it, generally speaking. Many merchants, of course, hate it. However, there are a few merchants that do like taking AmEx, even though the commission is higher. AmEx is more like a "Club" card than a regul... |
Why does inbreeding increase the likelihood of birth defects? | Everybody has bad genes in them - I remember a scientist quipping that there are enough genetic defects in the human genome to kill a person several times over. However, all humans get two sets of genes, one from each parent. As a result, many of the 'defects' you might have in your genes are simply overridden by the w... |
Where is all the water going? | The problem isn't that we're losing water, it's that we're just using clean freshwater faster than it's being replenished. You remember hearing in the cowboy stories about how great the Rio Grande was? [This is what it looks like today] after it's been dammed up for irrigation & drinking water up north. |
Is it possible for new major cities in first world countries to emerge and be as populous as the current ones? | Theoretically, cities build up for many reasons, but a key is economics and demographics.

What determines what a planet or other celestial body is made of? | As I have come to understand it it's gravity. more massive elements tend to wind up closer to a solar's center of mass in comparison to the lighter elements. This all happens when the emerging solar system is still a cloud of particles. So once these particles get pulled together in to planets you'll get planets with m... |
