Why do bridges ice before the road? | I may be wrong about this, but I was always told it's because of cold air movement above/below causes it to freeze much quicker, whereas regular road is partially insulated by the ground", 'The bridge is colder than the road because it is not insulated by Earth from below, and air over water is colder in general. |
Are vitamin pills beneficial for us to take, or are they a complete waste of money? Is eating healthy food the only real way to absorb nutrients? | Vitamins A, D, E and K are fat-soluble, meaning that they dissolve in fat, rather than water. This means they tend to hang around in the body for a while. A large overdose of these vitamins can be dangerous, especially a chronic overdose since it will build up in your system , but what's in a single daily multivitamin ... |
- how does someone get into whiskey/bourbons and able to pick up tastes? | Just like in beer, it takes training. You have to try a lot of different types and compare notes. It helps to find one or two you really like, drink them a bit to become very familiar with them, then compare others to your "base". |
Would the Attack on Titan 3D Maneuver gear work on Earth? If not, anywhere else? | No. 3DMG relies on rapid changes to momentum that would wreak havoc on a human body that weighs 150-200 lbs, especially since most of the force would be applied to one section of the body. Your second question is the more important. At 1.35 m/s^2 , there is a planetary body where the average human of the same dimension... |
What are the differences between alcohols (Isopropyl, stearyl, etc)? | It has to do with the other parts of the molecule. Alcohol just means it has an -OH group on the molecule, ethanol has two carbons attached to the OH, methanol has one. . The difference between propanol and isopropanol is the configuration of the extra bits. So propanol is just a straight chain of three Cs, while isopr... |
How are stores like Dollar General able to stay in business despite selling things for a dollar? | Some of it's special made stuff targeted to be under a dollar, others is just stuff other stores are looking to get rid of , so they sell it at a loss to recoup some of their cost. Dollar stores just ensure they always spend less than a dollar per item and thus they can make money.They buy their products in huge bulk q... |
My co-pay is $20, but without insurance it's thousands of dollars. How does the insurance company make any money? | In part, because the insurance company doesn't actually pay that "uninsured rate": because they are a huge customer, they negotiate much better rates for the drugs/services. You will never see what they pay: they get an invoice for the face amount, and then get a discount off that. It's somewhat the same for car dealer... |
Gyroids. Because the wikipedia page was so non-layman that it hurt to look at. | > A gyroid is an infinitely connected triply periodic minimal surface discovered by Alan Schoen in 1970 A gyroid is a surface in space, just like a plane, the surface of a sphere, or the surface of an idealized doughnut are all surfaces in space. Notice how a plane is unlike the surface of a sphere—the plane extends in... |
Why don't bugs flying inside fast moving vehicles smack against the back window? | Why would they? The air in the car is moving along with them. When you're coasting on the highway at 65 if you put your hand up in the air does it get thrown back behind your head? No because your arm is already moving at 65 MPH. |
When I'm walking I'm heels, why do the "clop" noises my feet make always seem like they are 2 different pitches? | They're coming from two different angles, and since they come from two different sources, the sound waves will bounce off two different sets of objects around you. It'll be a subtle, but noticeable difference. |
Is the center of a rotating circle at rest? | The very center of a CD it is rotating, but not moving in space There is, in general, a line through any rotating body called the axis of rotation. Any points in the body that fall on this line experience no motion due to rotation. All other points experience motion due to rotation. In principle, if you were standing s... |
How did WWII ship flak guns work? | At least for US ships, the classic flak burst comes from either the 40mm/56 Bofors, 3"/50 AA or the dual-purpose 5"/38. The biggest bursts would come from the 5", as you suspect. The general idea is that the 5" guns shoot down the planes as they're coming at the ship, so rotation required is minimal. When they get clos... |
What's to stop from getting the license, buying a gun, selling it to a criminal, and then just reporting it stolen? | That's a specific federal crime already, a straw purchase. It happens, but it's almost never prosecuted. Its what most gun owners mean when they say "Why not actually prosecute the laws already on the books instead of drafting new ones."', "Seems like a lot of work for very little gain. You could only do it once or twi... |
Why does ice taste bad with milk, even though it is great with every other cold beverage? | Personally I enjoy ice in my milk, I like it to be ice cold and don't mind if it'd a tad watered down at the end |
If you can create a smoke ring, could you make a regular air ring? | Yeah of course. Like you said though, it'd be invisible to us. There are underwater bubble rings with air though! It's all about fluid dynamics |
How are old videos that were filmed in black & white converted to color? | There literally was a person/team of people who colored it in. As you can guess, it is very tedious work. It is also very difficult of beginners, I'm a semi-pro at most everything Photoshop, but I can't for the life of me realistically colorize a B & W photo, let alone an entire film. |
'Scandal' in UK Newspapers over funding Hate Speech, and why many companies are stopping adverts being shown in these papers | Several newspapers in the UK, most prominently the Daily Mail , are considered by some to promote hate speech. For example, the Daily Mail often makes articles which aggressively target immigrants, foreigners, single mothers, people forced to make use of state benefits, etc for heavy criticism. If you're American, they... |
What exactly happens chemically that causes your body temperature to rise when you're sick? | Your body releases signalling chemicals that cause your blood vessels to shrink and move deeper into your body, making your body less effective at getting rid of metabolic heat. It's kinda like a car turning off its radiator. |
What's the difference between Body Wash & Shampoo? Why can't we use one for the other and visa versa..? | Not an expert, but I've read that the scalp prefers a different pH than the body. But this may not be significant enough to matter. OTOH, women tend to have longer hair than men and a shampoo may be better for longer hair. Lady Brienne of Tarth may ignore this. |
Can someone explain to me money markets to me like im 5? | It's no different than a regular savings account, just higher minimum balances which usually yield higher interest than a simply savings account. It is not linked to any external risks, most Money Market account's are FDIC insured. Rates are generally 25-50% better than the average savings. It differs from a Cetificate... |
Why is it advisable to block your license plate when sharing a photo of your vehicle? | License plates can be used to find where the owner of the car lives. Unless you're completely comfortable with random strangers knowing that, it might be a good idea to block the plates. |
Why do lower frequencies in speakers require more power? Shouldn't it use less power since the speaker vibrates less? | Another way to think about this is the question: Why do treble sounds travel farther than bass frequencies? To answer this, take a look at the waveform of the frequency in question. The treble wavelength will be much shorter, meaning that for the same power, an audio source can achieve a higher total sound output due t... |
Why converting human power to electricity in gyms isn't worthwhile. | Because the amount of electricity humans can produce through mechanical exertion is extremely small. A typical person on a bike generator can produce about 100 watts. Assuming someone is using the bike 24 hours per day, that would result in about 72 kilowatt-hours of electricity per month . A typical family uses someth... |
In terms of genetics, what is a 'library' | Basically it's a collection of genes that have been identified, that we know their purpose and we know the DNA sequence that codes them. |
Are there any rules about which company name appears on a credit card statement as the payee? | I am not 100% sure but I believe the written text is just a note field, the numeric references are the real information. I know that one UK credit card company actually offered the ability to change the text when they started experimenting with an online portal. |
Why do electronic devices have a limit on the storage size of MicroSD cards that can be used? | Right now, we see a pretty strict limit around 32gb, the point where larger cards must follow the SDXC standard, which also mandates a different filesystem. While for many devices this can be added in by a software/firmware, older devices that no longer see updates may never get that added in. While the 2-4gb limit bet... |
How are some car radios capable of spelling out song titles and artist names when tuning into some FM stations? | Radio stations do a lot of clever work to fit more information in the audio stream then just the audio. Originally an FM station were just a simple mono audio signal. However they found out that the signal quality were good enough to deliver audio signals at much higher frequency then the humans can hear. So they compo... |
How is the ozone hole "healing"? | Ozone is constantly being created in our upper atmosphere because of UV radiation from the sun. It's a good thing too, because otherwise that same UV radiation would cause all kinds of trouble for humans here on the ground. But in the previous century we had a number of machines, chemical processes releasing nasty chem... |
How does my tv, which has no internet connection tell me what the next program will be? | Assuming you have cable, your cable provider subscribes to a service called an 'epg' which stands for electronic program guide. This is the electronic equivalent of the TV guide magazine. This is sent to the tv on a special channel along with all the regular shows. |
What are incredibly niche stock images actually produced for? Are they commissioned, if so by who? | Stock photos are taken by random photographers that then give the stock company the rights to the photos in exchange for payment when purchased. Having photos on a stock website does not guarantee it being purchased. I 've been a model for almost a decade and worked with hundreds of photographers. Some of them create p... |
What is a Sievert and its SI multiples? How much is dangerous? | > For example, 3.58 µSv, is that a lot of radiation, or not so much? Would I, or any other body, be in danger around that? That's quite a small amount of radiation. We all get a little radiation when we go about living our lives. For example those who live in Princeton gets a little under 3 millisieverts/year from natu... |
Why is marijuana officially classified as a hallucinogen if you dont actually “hallucinate?” | There are tons of psychoactive chemicals in cannabis. They vary greatly from strain to strain. Some strains are bread specifically for their high or low levels of this chemicals. Some of these chemicals are in fact hallucinogens. Most of them subside after regular smoking due to building a tolerance. It's much more mil... |
Do the signs on the backs of trucks that say, "warning stay back 200ft, not responsible for broken windshields" carry legal weight? | They carry zero legal weight in cases where something falls from the truck. You can't unilaterally disclaim liability for negligence. Loads are required to be secured in every state. The driver would be negligent by either not securing the load or improperly doing so, and a single stone falling from a truck is an unsec... |
How do traffic lights 'know' when to change, etc.? | Some traffic lights are on a timer. Those are the lights that seem to take forever to change. Other signals are triggered by a pressure plate under the asphalt, you can usually spot these by a square "patch" looking piece of asphalt at the stop line. The mechanism used usually depends on the amount of traffic at that i... |
In the USA, what is life (in practical terms) actually like for illegal immigrants? Can they get jobs, legally drive, get healthcare, etc? | They cannot legally get jobs, they cannot legally drive as they cannot legally get a driver's license, they can get treatment at an ER but they cannot get health insurance, they cannot legally get an apartment because they lack the proper documents, etc. What this means is that everything they do is under the table. Th... |

System of Linear Equations/Inequalities? | Let's say you don't get an itemized bill but you want to figure out the prices at the restauraunt: You order a hamburger and a beer totaling $15 and on the second visit you order a hamburger and 2 beers totaling $20. How much does a hamburger cost and how much does a beer cost? h + b = 15 h + 2b = 20 We subtract the fi... |
What an 'Epipen' is and how it works? | An epipen is an easy to use syringe filled with epinephrine, an artificial form of adrenaline, and a few other drugs. It is one of the most efficient ways to delay an acute allergic reaction until you can seek medical treatment. If someone gets an allergic reaction and have problems breathing so you are not able to com... |
In evolution how did sexual differentiation come about, like males and females? | [Ah, wikipedia :)]. The reason is genetic diversity. If you have two genders, that's twice the genes to one specimen , which allows helpful gene selection to occur. The species then evolves quicker.In The Selfish Gene I believe it was explained that very very early forms of life found a reproductive advantage when one ... |
Why does wind or moving air feel cool to animals and humans? | When it is hot you sweat. Moving air makes sweat evaporate faster and evaporation absorbs heat making it cooler. Also, when the air is still your body creates a sort of "heat bubble" around you . When it is windy, a steady supply of cooler air is able to absorb more of your body heat. Heat transfers more quickly to col... |
Why do I feel like smoking about 13 cigarettes a minute when I'm drinking alcohol? | Alcohol gives you very poor impulse control. Nicotine is highly addictive, which means it gives you a strong impulse to smoke. |
freudian theory; id, ego and super ego | The Id is the primal, uninhibited part of oneself, which bases all of its actions on instincts and urges.

Basically, the Superego is one's idealized version of how he or she should behave in a civilized society, while the Id is the cavema... |
If there is no matter in space, what do the rockets push on to accelerate a ship? | That's not how rockets work. Rockets don't "push on" anything. They're not sneakers. By igniting a chemical reaction, they cause an action, i.e., projecting a stream of expanding gas in a particular direction. The reaction is moving the rocket in the opposite direction. Whether the surrounding environment is a vacuum o... |
How do geese seem to know exactly when to return? | They don't. They are actually pretty terrible at it oftentimes. I've been seeing small groups of geese flying north for about a month now, as Ontario has been gripped by The Winter That Shall Not Die. It's only in the aggregate that geese are good at this, but that makes sense, and is a fairly common pattern in nathose... |
Why do we start to salivate when thinking or about to eat spicy or sour foods? | It's a Pavlov's dog effect. We're conditioned to associate the smell of spicy and sour and even the thought of it with eating food, and so our body physically reacts. It's not specific to spicy foods at all. If you walked into a bakery every day and ordered a loaf of bread and then ate it, the smell of bread would prob... |
Why do postage stamps have curvy edges? | In the old days, stamps were printed on a big sheet of paper, and they 'd use a machine to poke rows of tiny holes in the paper so that it would be easy to tear off individual stamps. Those "perforations" would make the edges of the torn off stamp look wavy. Modern stamps are printed on strips of sticky paper with a wa... |
How can healthy individuals with no symptoms initially develop allergies later in life? | Also want to know this. Used to be allergic to cats and fine around dogs. Now it's the opposite. |
Why don't you see rain in sports tv broadcasts? | My guess is that it's the focal length. When they show the field they have to use a rather large focal length since the players are rather far away. When they show the bench they would use a smaller focal length which would include the rain. Depth of field is probably also in play here. Wider aperture for they players,... |
Can the POTUS issue Executive Order on withdrawing from NATO? | No. NATO is part of a treaty , and only the Senate can make or break treaties.

The President could order ... |
Why do electronics which have gotten wet, stop working even when they completely dry? | In addition to the damage being done on contact ; tap water, rain/flood water, etc contain a lot of impurities.

It's released from neurons in certain parts of the brain, where it binds to n... |
Why do humans still have to do their own taxes? Why isn't this process automated? | It is automated. In other countries. Lots of countries don't force their citizen to do their own taxes, although they're still allowed to if they really want to .

How are crimes solved years after the fact using DNA evidence? | DNA, kept in reasonable decent conditions lasts of several years. While it does degrade over time, it's half life is somewhere north of 500 years.1. Dna technology has improved significantly over the years. 2. Despite what csi shows, not everything in every case has dna tests done. It is expensive and slow and if there... |
Why does it take so long for major reform to happen if most of the general public agrees that change needs to be made? e.g. Marijuana and Gay Marriage | The government is designed to be slow to save us from ourselves. Having to go through the process theoretically vets new ideas and changes so they're not implemented hastily with no thought to the consequences. It may be inconvenient when the changes are positive, but it's there to prevent bad ideas from being enacted ... |
What happens when people die? | She is in you, and in your siblings . You carry her genes, she told you her memories, she taught you how to live your life.You'll get a lot of answers from a lot of different people.

How do we get songs stuck in our heads? | Short term memory has an audio component. When you rehearse something in your head it gets recycled into short term memory and reinforced. So you hear the song, your STM registers it, you rehearse it in your head a few times, it gets stuck! If you want a more in depth answer I would suggest googling “short term memory ... |
A Calabi–Yau manifold and other higher dimensional shapes. | You're not alone. Our brains evolved in a world with only three extended spatial dimensions and that means we simply don't have the mental wiring to be able to "visualise" more dimensions than that. Some scientists and mathematicians who 've spent years working on concepts of multidimensional objects claim to be able t... |
how CRE can pass its drug-resistance to other bacteria | DNA can be stored as small, circular, independently replicating molecules called [plasmids]. These can be passed from one bacteria to another in a process called '[bacterial conjugation]'. Basically the plasmid has genes that code for proteins that build a [pilus] which extends from the first bacteria and contacts the ... |
Why is the age of consent in some countries such as Japan and Mexico so low compared to countries like the US? | In Japan, the national government leaves it up to municipalities, who enforce higher ages such as 17. To some degree this also happens at a state level in Mexico. However, to answer your question more broadly: historically many societies have felt that sexual activity is permissible after puberty. It's only in the last... |
how does the money I spend for a CD get to an artist? | Depends on the term of their record contract. If they're on a label that puts their music up on iTunes for example, the label gets a cut and so does Apple.

Why is it better to start with cold water and boil it when making pasta or coffee, rather than starting with hot water? | It is a myth that cold water boils faster than hot water, but hot water can freeze more quickly than cool water due the [Mpemba effect.]', "Depending on the plumbing standards in your country, the hot water system may not have been built with any regard for the hygiene required for use in food. Being good enough to was... |
Why does the space shuttle or the soyuz need special tiles to reenter the atmosphere but spacex falcon does not? | Are you talking about the Falcon 9 first stage, or the actual Dragon capsule? If you're talking about the Falcon 9 first stage, that's because it separates from the rest of the rocket at a relatively low altitude and speed, and thus there's less heat during reentry. It also burns it's engines to slow down to further re... |
How are record sales calculated now that there is music streaming and the ability to buy one song? | Streaming and downloading services record the number of plays individual songs get, and this time is broken down into "record equivalent plays" which basically says something like "10 song sales is worth 1 album sale" even if it's all 10 sales of the same song off the album. Currently, Billboard equates 10 song purchas... |
Where do a lot of gay men get their lisp from? | I'm not a gay man but I am gay , so I 've spent a lot of time on the gay scene and tend to be friends with gay men more so than women. It's the same as so-called "ebonics" - it's a learned behaviour, to fit in. There's no genetic reason for it, it's just a case of fitting in with the pack. If your circle of friends all... |
How does a hospital medically induce someone into a coma? | giving someone barbiturates will put them into a controlled coma where the body can heal itself until it is ready. For more information on coma - _URL_0_', "Emergency room technician here, the medically induced coma you're probably thinking of is propofol. Its the stuff that Michael Jackson was using to sleep. |
why did the universe "start"? | We do not know. We cannot even say with complete confidence that it *has* a start, although the leading theories of the day suggest it. Current science is not capable of getting all the way back to "time zero," nor whatever occurred before that, if such a concept is even meaningful. |
How do Interim championships in UFC work | So champions in fighting are decided linearly: you beat the current champion now you are the champion, you get beat the guy that beats you is now champion.

How and why do men ejaculate with more velocity when they are more excited? | Welp, I just spent a good ten minutes reading about ejaculation on wikipedia, so now I'm an expert. Here's what I think, based on this sentence: > A prolonged stimulation either through foreplay or stroking leads to a good amount of arousal and production of pre-ejaculatory fluid. Increased arousal or longer arousal ti... |
Why are doors much easier to close when my window is open? | Because by slamming your door you push a lot of air into the car. This causes additional air pressure to build up in the car, which pushes the door open.Usually it takes at most a few seconds for the additional air to escape via various holes in the car, but that second is enough to hinder the door from closing.If a wi... |
How muscle relaxers only affect skeletal muscles. (Not organs/muscles like the heart). | They don't? What causes death on many of them is that it shuts down your heart or lungs. |
Where does the skin on the body stop being skin and become something else? Openings in particular. In the case of the face does it end at: lips? tongue? throat? | Skin is a specific type of tissue- epithelial tissue. The other tissue types are connective tissue, nervous tissue, and muscle tissue.

Why lightning doesn't knock planes out of the sky. | Okay, here goes: electricity will always take the shortest path to the ground right? Well, since a airborne plane isn't grounded, lightening strikes generally don't hit planes for this reason. However, they do sometimes hit home and when they do nothing happens. As ACrusaderA said, the light might flicker but it's very... |
How do cemeteries maintain upkeep after all the plots are sold | CPA Here Mortuaries and Funeral homes essentially are left with a perpetual liability in maintaining the burial grounds after all of the lots are full.

Why does wind make it so much colder? | A person's body produces heat, which radiates off of them and warms the air around them. When the wind blows, it blows the warm air away and replaces it with colder air. Also, people lose heat when their sweat evaporates, and wind speeds that process. |
Why do companies like Nikon sell cameras that around 16 megpixels but phone companies like sony and Nokia sell phones that have 20 to 40 megapixel cameras? | Resolution is only one aspect of what makes a picture good. And once you can't see the pixels any more, increasing the resolution doesn't help . The problem with having tons of pixels is that it means very little light hits any portion of the camera, so you end up with a lot of noise- the camera can't quite tell what c... |
; how does sound work? | Sound is waves, like you said. These waves overlap on each other and add up or subtract. This is called superposition. If you have several instruments, at every point in space, their sounds add up to one waveform. This is an example of two waveforms adding up: _URL_0_. There are two waves that are similar but slightly ... |
Why do people use complicated #hashtags? Doesn't it defeat the purpose? | A lot of hashtags are for the sake of reducing character usage and also to look cool.
