how do scientists determine how much water you need to drink? | The "8 glasses of water per day" thing is ridiculously high and is also a myth, apparently originally based on a misinterpretation of a 1940s article telling people to get 8 cups per day *including the water content of their food*. _URL_0_ But even that recommendation is somewhat suspect. Research hasn't conclusively s... |
Are Tesla cars actually better for the environment? | Right, so they use batteries. That means that we can choose where the energy for the cars comes from. You are right, if all the energy that we use to fill up the batteries comes from fossil fuels, we didn't really win anything. But here's the point: cars that are not electric do not have a choice. Their energy HAS to c... |
If you have previously received an organ, can the same organ be donated again if you die? | Typically no, unless it was some quick case . The act of extracting an organ typically creates scar tissue which damages the organ slightly.

why does your vehicle not get morning frost on it when parked under an overhang or carport, if it is the same temperature and has the same airflow? | Not exactly the same airflow, at least with the shelter on top. All that water vapour high in the air would first form and freeze on the shelter, versus being on your vehicle.

How does glue not dry inside of the bottle? | Let's take plan old white glue for an example. It is a bunch of sticky stuff in water. When the water evaporates, the stuff that's left behind is frozen into place. When it's in the bottle, there's nowhere for the water vapor to evaporate to, so it stays wet and sticky. |
What are the practical applications for quadratic equations? | They are used a lot in geometry, since distances in a plane are found with the pythagorean theorem a^2 + b^2 = c^. If you start with one of those numbers and want to find the others you often have to solve a quadratic equation. If you want to build real life objects based on an x-y plane you'll need that.The most commo... |
If somebody steals a piece of art, how can they make money of it? Wouldn't they be recognized and caught as the robbers if they are trying to sell it? | If they sold it on eBay then yes.

What happens is the confac... |
Why is it that storage devices have less space than what they claim? (a 32GB iPod touch has 28.5GB of useble space) | There are two ways of measuring the popular SI prefixes Giga- and Mega-. One way is using base 10. In this way, Mega- would be 10^6, and Giga- would be 10^9. The other way is using base 2. Using this, Mega- would be 2^20, and Giga would be 2^30. The problem is, that the base 10 versions don't equal the base 2 versions.... |
Why can't we remove salt from seawater to solve water shortages? | we can, its called desalinization. huge pumps force water at super high pressures through special filters. Its very energy intensive though, and the plant is expensive to build, so typically, whenever there is a drought, it comes up, but then the drought ends before the project ramps up so it gets shelvedWe can but it ... |
Why do companies advertise with Megapixel and Megehertz while this doesn't say much about the actual speed/quality of the product? | There are a couple of reasons for this. The first is likely heritage. Mpix and MHz used to actually matter. For instance, the first digital cameras on the market had < 1 Mpix which was really poor quality. So there was a race to get more pixels because at that time it did matter . Same goes with MHz. Early CPUs could o... |
If the bible is 1,281 pages how did so many churches get so many bibles before copying machines? | Yes. Monks in monasteries copied them by hand all day long, making beautiful illuminated texts. It wasn't until Gutenberg invented the printing press with wooden blocks that made mass producing them easier. That's also why education and literacy was so limited to the upper class; books were expensive and hard to come b... |
What biological function does grief serve? It doesn't seem necessary for survival yet is a firm part of the human (and animal) condition. | Let's say grief wasn't a thing. You're some proto-human and your mate dies. Oh well, time to find a new mate. You've removed a very strong motivator to keep your mate safe and cared for. As a result you've negatively impacted your ability to produce additional offspring. Same can be applied for close social connections... |
How does “after hours trading” work? | afterhours trading is open to anyone, its not unfair to anyone. there are no market makers, so things can be less liquid, it requires a buyer and seller to agree to a single price and the transaction is executed by a computer.

The take a penny, leave a penny system | There's no real "system" with any organized rules. It's simply a tray where people leave loose pennies. There aren't enough pennies in the tray that grabbing them all would actually be worth any significant value, so nobody bothers. But it's good for someone whose bill comes out to $10.03 or something - they can just t... |
Why shotguns cannot fire in a straight line like other firearms. | Shotguns fire a barrage of small projectiles that are susceptible to interference from outside forces, like air resistance, and the fragmentary nature of the shot means energy is overall wasted compared to a jacketed bullet. The strength of a shotgun is in the numbers, with hundreds of little shells spreading the targe... |
Why do carbonated drinks burn your nose when you burp? | The short answer is CO2+H2O < -- > H2CO3 < -- > HCO3^- + H^+ So, when carbon dioxide dissolves in water, it forms small amounts of carbonic acid. Acid tends to activate sour taste receptors, which gives carbonated water its refreshing mild tartness. In adequate concentrations, acid can also irritate mucosal membranes Y... |
Why is no mouth CPR what everyone is told to do now? | The breaths aren't worth doing. Keeping the heart pumping is far more important. This is because while people will lose consciousness from carbon dioxide build up in a couple of minutes, the average person actually has enough oxygen in their blood to stay alive for for a while if the heart is pumping. There's really a ... |
the laws of war and why countries should care about them. | The laws of war are a body of treaties and customs for how war is conducted including what weapons may be used, what is a legal target, how prisoners of war should be treated, etc. While wars inherently involve violence and suffering, the laws of war try to limit unnecessary suffering. Countries should care about them ... |
Is flowing water harder to freeze in frigid temperatures? Why? | Still water can freeze at the surface, indeed because water around freezing is less dense than water at 4C, it almost has to. Flowing water must chill the whole body of water to 0C, which takes** much** longer. |
Why can't we domesticate other wild animals? | We potentially could. But domestication is a process of many many generations that involves changes at the genetic level. In other words, it takes a lot of effort and a long time. You have to have storage for the animals and their care and feeding, you have to guide their reproduction through generations, waiting for t... |
If cars running on hydrogen became more common wouldn't it increase the amount of water vapor in the atmosphere and cause more rain? | Conceivably, yes, but keep in mind that gasoline and diesel also produce a large amount of water when they are burned--ever seen the exhaust of a car on a cold morning? That's the moisture in the exhaust showing up as fog briefly before it dissipates, much like when you see your breath in the same conditions.Theoretica... |
why don't dogs acknowledge/recognize themselves in the mirror? | What you're talking about is "the mirror test." It takes a certain amount of intelligence to look in a mirror and recognize that it is a reflection rather than just another space. Those animals are also able to recognize a reflection as themselves. Only a few animals pass the mirror test. Humans, chimpanzees, gorillas,... |
When in an air crash, like the Malaysia passenger jet, what specifically is it that kills you? | Blunt force trauma, in the absence of other injuries, such as vaporization or disintegration.

Why is my internet speed 40 Mbps, but files only download at 2-4 Mbps | Your internet is specified in mega**BITS** per second, while your computer denotes download speed in mega**BYTES** per second. At best your computer will report 1/8 the number since a byte is 8 bits. Then there's the issue that your internet speed is specified in terms of the raw number of bits per second being sent, b... |
If college education at public institutions became free of charge (to students) what happens to private institutions? | Realistically, not much. Cost to attend is rarely the barrier that prevents people from going to college; student loans are easy to get . Moreover, in-state tuition for most public universities is very low - [UT Austin is only $10k a year in-state] - making cost even less of an issue. Private institutions have always j... |
How do trees that are hundreds of meters high get water from their roots to their leaves? | Think of the tree as a huge pump. The roots are actively pulling water out of the soil, while the leaves are transpiring water. The internal conductive tissue in trees are the major mechanisms. These small tubes are how the water can move through the tree. Capillary action is how water sticks to itself, which allows fo... |
Why do cell phones and laptops get hot when they have been running for a while or running very hard? | Great question!

Still, others may find that their body isn't working on the right time scale; their bodies think that... |
Why does your brain keep bringing up thoughts you would really rather forget, yet forget things you feel are important to remember? | I'm no scientist but I think that evolution inherently causes us to remember the bad so that we avoid coming across it again so that it doesn't kill us. The good stuff is just happy memories that float away like all the good puppy dog kisses and cat snuggles you ever had. I bet you don't remember them. You remember tha... |
table partitioning in something like pgsql | By using partitioned tables you reduce the amount of data that has to be processed at once when you query your table. Imagine a table containing 10 million orders. Quite heavy to search there, so you add indices. Now you can get your data even faster, but still not optimal because a lot of data has to be loaded into ra... |
The water crisis in Michigan | Flint used to get water from Detroit . Politicians wanted to save money and use the Flint River instead. Despite a study that said it was not a good idea, they got switched to Flint River water. The Flint River was a lot more corrosive than Lake Huron.

Apart from poisonous spiders it seems like nobody is deathly allergic to regular spider bites, unlike bee stings which many people are allergic to. | FYI, spiders are venomous, not poisonous.

Why do we get carsick? And why does sitting in the front seat make the nausea go away nearly instantaneously? | Car sickness happens when what you're looking at doesn't match up with the motion being reported by your inner ear.

What's holding us back from utilizing a breathalyzer-like test for THC? | THC is much less volatile than alcohol and is unlikely to make it across the blood-gas barrier in the lungs to be exhaled in breath. It also probably spends less time in the blood stream than alcohol, but I don't really know that. I am only saying that because I know it is much more soluble in fat than in water which i... |
How does the UK function? | Until relatively recently, most of the UK was run by the UK government with only local councils underneath them.

Why does food taste cold at room temperature and drinks taste warm at room temperature? | Perspective. You're used to eating food that is supposed to be warm, warm. If it's not, you think "not warm" = cold.

There ar... |
Why does a mirror, which is the same in all directions across its surface, reverse left and right but not up and down? | What gives you that idea. Face a mirror. Raise you left hand.

This is how you can do things like twist and bend and scrunch and be punched and squeezed. And how you can shove things up your ass, apparentlyWith enough patience and train... |
Why do iPhones and Louis Vuitton bags' prices are standard all over the world yet medicine prices vary extremely worldwide? | Because drugs are very heavily regulated relative to consumer products.I work in a pharmacy as a cashier / assistant and I see people paying different prices for the same drug! It isn't even a geographic thing. It all depends on your insurance and how much they pay toward your treatment and what they expect you to pay ... |
How did American English become so drastically different than British English? | Short answer: They're not dramatically different. It's fairly easy for speakers of American English to understand British people, and vice versa. Accents can occasionally be thick enough to blur understanding, but that's true within each nation as well -- it may well be easier for a Londoner and a Chicagoan to understa... |
Why is a week made up of seven days? | The seven day week is chosen because of the 28-day lunar cycle. Every 28 days, there is a new moon, which is really visible - when you first see a moon at sunset. This makes dividing time into lunar months obvious Dividing that lunar cycle into 4 just made sense - the quarters or the moon, when the moon is half light a... |

As an example: Suppose the US government takes the 2 dollar bill , changes how it looks and renames it the dualer. One dualer is now worth 2 dollars. Now, suppose they get rid of all the doll... |
how does WiFi work in a megalopolis like NYC? In a small area with only 11 channels shouldn't the interference from thousands of neighbors render it useless? | 2.4 GHz routers get to use 11 channels and 5Ghz has 23, so while there is certainly interference and degradation, most people don't see a significant slow down at close range, especially if they are smart at picking less crowded channels. |
Why is it that people with intellectual disability can paint or play instruments extremely well? | I really doubt that there's a statistical relevance to this. I.e. intellectual disability doesn't inherently make a person better at musical instruments. I don't see how it could. But in news they tend to use sensational stories, and it's more out-of-ordinary for a disabled person to play an instrument well, than for a... |
WHY don't cats like water / getting wet? | Just depends on the cat. I have 4, some who like water, some who don't. Biologically speaking, domestic house cats do not have waterproof oil on their fur , so unlike a dog like a Labrador, the cold water actually reaches their skin, chilling them. Most cats don't like that feeling, so they learn to avoid it. On the ot... |
