Why do car radios turn to static in road tunnels and not go silent? | No squelch function. In a nutshell it comes down to cost. There are technologies, quite old ones really, that are able to filter the static but there are too few tunnels to make it worthwhile installing this in cheaper cars.In AM radios, there's a thing called automatic gain control. Essentially, the amplification of t... |
Why hasn't the larger part of Muslim world taken a bigger role in eradicating the extremist sects that give their people such a bad reputation? | Why do you think that they don't?

Why do I wake up early on days I am free, but on days where I am busy I want to wake up late? | I'm gonna take a leap here and say that I think this has more to do with psychology than an actual explanation. So, I think that you probably dislike whatever it is that you do for a living or are otherwise having to wake up for normally. That disdain grows over time to outright contempt for which you do not want to be... |
Why does a pile of broken glass look blue? | Window glass is actually greenish.

Why dont all the oceans have the same amount of salt content? | The ocean is not a closed system. Acidifying CO2 is constantly dissolving into it, there's biological turnover of a slew of compounds, run-off form land, the flood of minerals from geothermal vents and underwater lava flows, etc. The salts in the ocean don't so much affect the pH as they act to buffer the changes. In t... |
Why are eggs in so many foods that don't taste like eggs? | Eggs are a great binding agent. Binding agents help all the other ingredients come together as a specific shape, or to just hold together. They can also add texture. So by adding eggs to your brownie recipe, you get that wonderful, moist, delicious, "stuck together" texture, while also making them keep their shape. Oth... |
What is the difference between genetic modification and selective breeding? | Genetic modification involves editing the genetic code directly, whereas selective breeding involves only breeding organisms with particular features- so that, eventually, the whole flock/crop/population begins to exhibit the desired traits. All in all, they both involve in tinkering with the genome- just selective bre... |
Why does a combustion engine need gears but electric cars do? | A combustion engine can only rev so high due to mechanical limits, so it needs gears. Plus it's peak torque and power occur in a fairly narrow RPM band. An electric motor generates power through rotation like a jet engine and the limits on that are a lot different than a gas engine which relies on reciprocation.Electri... |
People say that O.J Simpson was found not guilty because the prosecution mishandled the case. What does this mean? | The prosecution made lots of mistakes: * They didn't call certain witnesses who could have bolstered their case* They had OJ try to put the glove on.

Why are video games/dlc's primarily released on weekdays? | There's a few good reasons. There's better media coverage during the week, so you're more likely to get press for your release than you would over the weekend.

Do animals experience emotions? If so, do they differ from human emotions? | Kind of hard to tell exactly what animals experience, since we can't ask them. However, science suggests that many of them do. PET and fMRI show their brains acting the same way ours do when we experience emotions.My dogs seem very happy when I come home, sad when I leave, and excited for walls and rides in the car. We... |
Do car gears dictate a top speed, or would a car with an automatic transmission going down a big ramp in drive go faster than its top speed? | Wind resistance mainly dictates top speed. A car has to push itself through air, which takes energy. When the energy that the motor puts out equals the energy of the wind working against it, you stop going any faster. * yes, other things also dictate top speed, such as rolling resistance and other mechanical losses, bu... |
How do bugs and glitches in electronic software occur? Isn't code just a formula? How can maths break? | Code is a set of instructions; literal instructions. The computer doesn't know what you *want* it to do, it only knows what you *told* it to do. Bugs can happen when your instructions are faulty, or something unexpected happens. **Faulty Program for driving a car** 1. Walk to the driver's side front door of the car2. O... |
Why is it okay to eat under-cooked beef or eggs, but considered too risky to eat under-cooked chicken or pork? | Unless it is ground up, beef only has bacteria that are harmful to humans on its outer surface. Look up "Pittsburgh Rare" for the extreme way to have a steak. Eggs are self-contained, no exposure to the outside so safe to eat. Chicken and Pork both contain bacteria with the flesh that is harmful to humans. So you need ... |
What is the difference between a defibrillator and the device used in the hospital to restart a heart. | They're both defibrilators, but the one you 've probably seen around is an AED- automatic electronic defibrilator.

Why didn't Human speciate | There were different [species of humans], but we've outcompeted or outbred them. Given enough time, we could begin to speciate again, but at this point there is so much interbreding that it's hard to really say that, in the long run, any group of humans will be isolated enough for long enough to speciate. |
How do they get trains into underground networks such as the London Underground? | The London Underground has a lot of above-ground depots that function like normal train depots they use. I'd bet most undergrounds have a similar system for getting trains down. |
how does sleeping cure a headache? | What sort of headache? That agony-at-the-base-of-skull headache?Cos that's usually from sleeping badly /tension.

How is Bitcoin to be the future currency if there will never be more than 21,000,000 of them? That seems like so little for so many people. | A bitcoin can be divided into smaller units so the value of a single bitcoin would be driven up so that 21,000,000 would equal the total amount of money in circulation today.

why does the moon sometimes seem to stay in pretty much the same place low on the horizon for hours, only to seem to move drastically higher in like an hour? | This actually has little to do with the moon and everything to do with your brain. The moon is nearly stationary in the sky while the Earth rotates under it. With this, it basically behaves like the sun . Knowing this, we can safely say that the moon is not jumping around. Your brain, however, is built to deal with ter... |
How do ancestry tests figure out where my family came from? | They don't really tell you where your family is from.

How does time exist? How is it not just a construct of humans and their need to measure their existence? | We experience the arrow of time, cause and then effect. You cannot have cause and effect occur simultaneously, therefore, something must separate them, we call that thing time. We can't say time is real, or how we experience it is correct. But for your examples, a car doesn't just get mileage, it accumulates it, over t... |
How can people ask to have their face blurred on camera in a public place such as a street in the city? | Your image cannot be used without your permission for commercial purposes.

Why do humans vomit at the sight of something exceptionally disgusting? | It's a protective instinct. Think of our ancestors who may be interested in a left-over meal.

Humans have been a social species for a long time an... |
Why can't bots check the "I am not a robot" captcha? | The checkbox is not the real test. Checking a box is easy. What it does it is reada your mouse movement while you're on the page, and since you move the mouse in an organic, imperfect way it decides you are not a script or "bot".[From May 2016:] Google is keeping its algorithms secret so all we can really do is make gu... |

If you eat a pound of rice you will be one po... |
how do sites like Reddit manage to store all the content they do? | The thing about Reddit is that it is all text. It doesn't host images . Also, text compresses nicely .

One TB is holding one trillion characters in a text... |
Why is the U.S. Soldier who killed Afghani civilians being tried in the U.S. for his actions? | He will be tried under the UCMJ, which holds jurisdiction over all military personnel.

What would happen if America's "too big to fail" banks actually fell? | Rapid deflation. When you put money in a bank, the bank loans that money out. In civilized nations, they loan out up to 90%. So 100 dollars in the bank is 190 dollars in the economy. Except the 90 dollar loan also gets put into a bank, and 81 more dollars are lent out. So, for every 1000 dollars in the economy, 900 dol... |
Why is mifepristone so tightly controlled? | Because abortion is a serious medical procedure, and doing it by drug rather than by surgery doesn't make it that much less of one. There are significant medical risks which the patient has to be made aware of; it would be horribly unsafe to just let someone drive to a pharmacy and pick up their mifepristone pill. |
What is carried interest provision? and how does it work? | The way that the U.S. Tax code is structured, any compensation that you receive above a certain threshold are taxed at a higher rate.

But a lot of things don't have a smell to humans... |
How are we able to 'sense' when someone is looking at us or that "gut feeling" of something being wrong? | Your brain processes a lot more information than you are consciously aware.

Why do king size cigarette packs cost the same as regular packs? | The vast majority of the price of cigarettes in the UK is tax and duty.

We can get a lot more specific with it ... |
If a couple has five sons, how is possible that their next baby has a 50% chance of being a boy while it is simultaneously statistically unlikely that they'll have six boys? | The two probabilities coexist because you are asking different questions. Question 1: Given that a couple has 5 sons, what is the probability that their next child is also a boy? Answer: 50%, because the genders of the previous siblings does not affect the next outcome.

Why isn't Russia a heavier contributor to modern pop music? | I think there are two reasons. The first is simple -- Americans mostly like their pop music to be sung in English.

Of course there have been plenty of breakthrough Latino singers in the US but it's still rare that their biggest hits... |
Why do we always ask animals and babies what they're doing, even though we know they can't respond? | A large proportion of our language is either in tone of voice or body language, for the most part this is subconscious so when we ask babies and animals how they are doing it is also expressed in our tone of voice and body language. Whilst babies and animals can't fully comprehend what is being said to them what they c... |
How do astrophysicists know the light that comes from this particular star is x light years away? | It's called parallax. The basic idea is that if you look at a star during one point of the earth's orbit and check it's position relative to something you know to be much further away than it then 6 months later do the same measurement and see how its position has changed, you can use the angle of this change to draw a... |
why does 720p look the same level of clarity on my iPad as it does on a tv? | Because resolution refers to how many pixels there are from the top to the bottom of the screen. Since you have the same number on both screens and you look at those screens from far enough away that all the pixels merge together in your brain, the images look the same. This is also how jumbotrons in stadiums work. The... |
Why do numbers on credit cards have to look all funky, instead of just being in a normal font? | Modern cards that don't used raised numbers might use a sensible font.

Why do we close our eyes when we suddenly hear something really loud | We clench our jaw, too. It's what little we can do other than covering our ears to suppress noise.

Why do humans need to brush their teeth? What did we do before toothpaste? | We need to brush them since they need to be freed from bacteria. If we wouldn't we'd lose them way to early in our life.

Why are Ebola-infected aid workers being brought to the US? | They are doing this because we have better means of researching a cure in the US than we do in Africa.

If a northerner du... |
How does memory work for 3-4 year old children? | It's not that children have no memory at all - it's that, as we age, our brains overwrite unnecessary information with new information. *As adults,* we often can't remember things from when we were very young - but this doesn't say anything about a child's memory when they are still that age. Some suggest there's a lin... |

The variety of coffee brands and their kinds. Which one should I get to get the most out of it? Most caffeinated? Instant coffee or make your own espresso? | The variety of coffee types would require a full essay to explain, but it pretty much comes down to local variations in soil and other environmental conditions, plus a large dose of marketing.
