How would you get it there? Pound for pound, going to the moon is expensive. Really expensive. How would you service them? Getting a technician up there is really really expensive. How would you protect them? Earth has mild temperatures and magnetic protection from solar flares. The Moon doesn't. We could but it would ... |
Most of what your brain does has nothing to do with "thinking hard". Rather, the energy is primarily going towards just keeping all the systems operational. While it would no doubt be possible to measure some small difference in energy consumption based on use, this difference probably wouldn't favor the sort of thinki... |
An OLED tv is a tv made up OLEDs - Organic LEDs. It works basically like a regular LED tv. To explain the significance of LEDs, I'll have to explain LCD displays first. Liquid Crystal Displays work by having a screen-wide backlight, and crystals in front of that backlight to manipulate the light it gives off into a vie... |
Pilot here. The weather has a serious effect on aviation so it's extremely important to understand how it works. Many of the answers in here are either saying "It's because clouds only form in warmer air" and "The clouds insulate the ground preventing the heat escaping. Believe it or not, they are both as accurate as m... |
This website is great at breaking down what you need to know URL_0 |
Your eye muscles (muscles in the eye that control the lens ), when relaxed, are naturally focused on what is far away. The eyes also have to turn slightly towards each other to be able to see things that right close to the face. This takes energy and eventually the eyes get tired. Generally speaking, your eyes focus to... |
Almonds are seeds, almond seeds are dicots, meaning they have 2 cotyledons. When you split the seed in half you are exposing each cotyledon Therefore both sides of the almond are not completely joined Botanist here: They're cotyledons, aka "seed leaves". As the seed germinates the developing plant uses them for energy ... |
The Roman Calendar had the New Year starting in March and went like this: * Martius (March) * Aprilus (April) * Maius (May) * Iunius (June) * Quintilis * Sextilis * September * October * November * December At some point January (Ianuarius) and February (Februarius) were added, but different versions have them placed i... |
Because it's not (authentic) Cheese. It's made out of at least two different kinds of cheese and processed, therefor making it a cheese product. |
It gives the blade a point to drive forward, if that makes sense. Imagine you have a big juicy steak in front of you. You grab your fork and knife and get ready to cut a bite. Your knife is perfectly straight from the handle to the tip. As you try to cut your steak, the tip of the knife keeps stabbing at the meat and i... |
They have different mechanisms of action, the common denominator of being addictive doesn't really say a whole lot. Xanax is GABAergic, which is something most depressants share: they act on a specific type of receptor causing disinhibition and sedation because there's more GABA (a chemical that stops and slows down pr... |
So actually Venus spins the opposite direction, probably cuz some big thing hit it early on in it's development. The rest spin the same way because our solar system started basically as a spinning disk of dust. The whole disc rotates the same way, meaning the small individual parts also rotate the same way. Those tiny ... |
These names represent different business entities. A business entity is an organization founded for doing business that can enter into contracts and sue or be sued. Let’s say, for example, you start plowing driveways for work. If you don't create a business entity, then you're just considered to be working as yourself.... |
surface area vs internal guts. You have an exponential growth problem. Cells need to take food in and get waste out through their cell wall. When a cell is really small, that works out fine. But if you make a cell larger, the amount of potential mass you can have *inside* the wall grows faster than the amount of wall y... |
I am going to take a dig at this. I think the exact word you are looking for is "Rocking to sleep". As to why Rocking helps us sleep, it is a matter of brain waves. Firstly, we have been put to sleep a hundred times since our birth by gentle swinging motions of our parents. Hence our **brain associates these gentle mov... |
Because they are still in the process of growing and that takes a lot of effort and energy, which leads to more recovery time, thus more sleeping. |
There has been a weird and surprising amount of research done on belly button lint! Lint collects mechanically by body hairs, as you move. Most lint comes from your underpants! There's a lot of blue dye in clothing. |
alcohol and tobacco were legal before we knew of their risks, and now its the status quo, which is hard to change. Im sure the FDA would love to ban tobacco for sure. but thats not how the govt works, there are other forces at work, namely the smokers who are already addicted, and the industry/jobs that it represents. ... |
first off, you have to understand there are several types of match fixing. Most types revolve around a binary result (win/loss, yes/no) because that means fewer variables. Most of the time, the people getting something out of it are gamblers (who bet on the pre-destined result) and participants (who are paid to help cr... |
Before calculus, you computed the perimeter of a polygon inside a circle, then the perimeter of one outside a circle, [like this]( URL_0 ), and took their average. The more sides the polygon has, the better the approximation. After calculus, they discovered infinite series that added up to pi, like: 4 - 4/3 + 4/5 - 4/7... |
The reason for anti trust laws is to make sure companies will compete against each other to make the best products at the lowest cost. If T-mobile and AT & T would merge they would become so big that nobody could be able to compete against them. In a lot of markets these two companies are the only available option but ... |
Your eye has photoreceptive cells that respond to certain wavelengths of electromagnetic radiation striking them. This occurs because those photons are absorbed by proteins in the cell, which trigger a change, that generates a signal sent to the brain. Those cells do not absorb other wavelengths, including those of inf... |
The eyes are trying to focus on an image that is not actually out of focus, it is just that the brain cant make sense of the image. The brain recognizes several familiar patterns, but cant quite focus on one at the time. |
When you have the flu, your immune system diverts the white blood cells to fight off the flu virus, thus leaving your muscles and joints feeling sore and achy. ... This causes inflammation in muscles and joints, resulting in pain in a similar way to mild arthritis or rheumatism. Copied from Google. Either way I hope yo... |
Extensive testing of these systems on all terrain has been conducted and will continue to be conducted. There are standard responses to certain situations that we should all do. For example if you're skidding, you turn into it to regain control. The car can do this, but faster than you can even think it. Modern cars ev... |
When sunlight hits water or ice in a cloud, it refracts, bending in direction. With small clouds, some sunlight bounces around inside and eventually makes it out towards the ground. Rain clouds are larger, so less sunlight makes it through the cloud without being redirected away. Less sunlight passing through makes for... |
Like /u/donsterkay said, such companies usually make their money through advertising. It's worth noting, though, that not all of them do shady stuff like cramming ads on all your pages. As is usually the rule on the internet, for every 100 online services there are 99 scumbags and 1 honest fellow. Those two you listed ... |
Burgot gave you 3000+ karma on /r/leagueoflegends, so you are satisfied. Why? Burgot is very odd, yet satisfying. Therefore, he is odd and satisfying. |
This is known as 'semantic satiation' and there isn't much academic literature on this specific effect from my brief research that I did just now. However, from what I can tell it's related to other effects so I'll base my explanation around an understanding of those as well as a bit of research. As a disclaimer, I'm a... |
You cycle through different stages of sleep, ranging from lightly asleep to hardcore asleep to dreaming: N1, N2, N3, REM. N1 is light sleep, the transition between awake and asleep. During the night, you move up and down these stages. Sleep isn't an on/off switch--it's a super complicated system. A lot of different thi... |
I know this! When a man sits on a toilet, the head of his penis often comes in contact with the inside of the toilet seat. By having a gap, this prevents germs from being transferred from dick to dick. (Ladies never blow your man if hes just taken a crap in a public restroom without the seat notch) Men also for some re... |
So the big common misunderstanding is that Facebook, Google, and most large companies **don't** actually sell your personal information. Yes they collect it, but they don't sell it. Smaller and more unscrupulous companies will sell your data though, usually to email spammers. The big guys instead collect it, research i... |
Because the dark side doesn't send out (reflect, really) enough light to be able to shine through the blue light that is "created" in our atmosphere, while the bright side of the moon does. It's the same reason the rest of the dark sky isn't showing. It's not bright enough to be visible through the general brightness o... |
The big thing is if you are rich, you (usually) don't have to worry about a regular paycheck to get by. That gives you a lot of options to avoid (legal) or evade (illegal) taxes. For example, instead of a salary, you might choose to get paid in stock options, that don't get taxed until they are exercised. If you own a ... |
Iodine is added to salt because there used to be a real problem with iodine deficiency in the US, leading to all sorts of thyroid issues. Goiters everywhere, man. Salt was the most obvious candidate for mass-supplementing, as almost everyone used it, it is nearly impervious to spoilage (although an opened package of io... |
You're more worried about what could go wrong than what can go right. Same reason you fail to notice something in the background of no importance but your brain instantly alerts you of a perceived threat in your periphery (like noticing a giant spider in the corner of a room). Your brain alerts you more of the things t... |
They don't work. They are a form of fortune telling, and are easily manipulated by the dowser (scam artist) by tiny pressure and tilting of the hands. |
Bread rises when baked. The flat bottom portion was on the bottom of the pan, and the "fluffy" top was allowed to rise up in the over. The same thing happens with muffins, and loaf bread, and lots of baked goods. You could flip it upside down, but it generally makes sense for the flat portion to be the bottom. someone ... |
It is exactly like taking responsibility for diabetes, and then changing your lifestyle to account for it. It is a medical condition, but one that has both physical and psychological elements to it. If you don't fix the mental stuff, fixing the physical stuff does nothing. You're not taking responsibility for the addit... |
The larger size audio jacks are preferred in pro-level gear because it can be built much sturdier, and with high end beefy metal parts withstand thousands and thousands of plug/unplug cycles. Functionally, there isn't a big difference. But since for musicians this stuff can spend a ton of time getting thrown around on ... |
The mucus comes directly from the surface of your nose, called a mucous membrane because it produces mucus to protect itself and as lubrication. This mucus is a combination of long, stringy proteins and water, which allows it to stick to most surfaces. We produce a ton of it while we have upper respiratory tract infect... |
Because everybody hates change. Week 1-4 of a UI overhaul, everyone hates it. It's all different and you have to find the stuff you want again. Once you figure it out you stop caring and usually whatever new/optimized feature gets a jump in usage, which is why they made a new UI in the first place. |
For 7 years i shot up meth and heroin pretty much every day. Between not eating and scarcely drinking enough fluids to stay hydrated, your body begins to basically go into starvation mode. Scabs come from picking because while on meth if you cant stay busy you'll pick at anything you can on your skin thinking something... |
Suicide. Chronic depression, especially when combined with other mental illness, drastically increases a person's chances of attempting suicide. You don't die from depression. It is a stepping stone to diabetes, suicide, and heart attacks. Depression makes it really easy to sit around eating fast food all day and never... |
Report them to the police and contact a lawyer to sue them. You should also call your phone company and tell them what is going on. Have you tried asking one of these people what information they've gathered about this company? I mean, if you know it's an air duct company, what's the company name? Can you look them up?... |
When the nerves in a certain area are deprived of their nutrients especially electrolytes, they begin to fire frantically. This causes the pins and needles feeling. |
Sound is not just a vibration through air, it's a vibration through anything with mass. The air inside the room will vibrate then the vibration will hit the walls/doors and cause them to vibrate too - the vibration propagates through the solids that make the walls/doors and then passes on to vibrate the air outside the... |
Computer Engineering is about the hardware and making of a computer. answer the question: how does it work? and how do i make a new functioning one? how do i make a better one? IT is about using existing devices in an environment. answer the question: how do i deploy these devices in an office so that 100 people can ac... |
Aggressive reaction syndrome (ASR). It is commonly found in primates and is a response of the enlarged amygdala. When we get angry it's essentially the amygdala taking over and telling the brain it's time to get physical and assert ourself. Since we're social animals with complex hierarchies it's important to show othe... |
This is similar to a previous topic, except [this ELI5]( URL_1 ) was saying you'd feel worse at night due to your cortisol levels dropping, which is what [this article describes.]( URL_0 ) Basically your cortisol peaks during the day and therefore your body is not actively fighting off infections or viruses, so you fee... |
Every person has different bacteria in their skin that creates their own scent. Combine yours with your SO and it will a create a seemingly unique scent. |
Runways are routinely plowed and deiced by airport ground crews. If it is snowing hard enough that the runway can't be cleared the airport is closed and traffic is diverted to other airports. |
The rise-over-run specifics aren't the same as regular stairs so we aren't used to the setup which makes us feel "weird" while walking up or down unmoving escalators. |
A jar won't open is often due to pressure. Hitting a jar from the bottom rarely works for me. What I do is put it under running hot tap water for 30 s and it usually opens. When it's heated up, pressure in the jar changes. Someone please correct me if I am wrong Tapping or tampering with the lid loosens the seal, allow... |
It depends on the specific of the deal as announced and approved by the shareholders, but most commonly the shared will be converted to shares in the acquiring company. Sometimes they'll issue only in full shares and pay cash for fractional shares and sometimes they'll issue fractional shares. As an example, I owned 15... |
Imagine a room with some 3-dimensional objects in it, like a sphere, a cube, a cone, a pyramid, etc. The room and the objects are uniformly white in color, and there's no light except for a flashlight that you can shine into the room from different locations. Every time you shine the light inside the room, you take a p... |
The Treasury does not know how much cash they need to create. They are told by someone else called the Federal Reserve Bank how much to create. People and businesses don't like to have too much cash laying around because it could be lost or stolen and you have to physically hand it to someone to use it. So they give th... |
Two different reasons. Capsaicin as found in most peppers causes a runny nose because it irritates the membrane and mucous production increases to clean itself. Cold air causes a runny nose because cold air tends to be dry air, and lungs need to be wet inside in order to work. So you get a runny nose to keep your lungs... |
I think you're reading the inference of the phrases incorrectly. The phrases exist because they are exceptions to the norm. A Daddy's Girl is called that because it is worth remarking on(and vice versa) it being assumed that most children latch on to the parent of the same sex, therefore the phrases show a difference f... |
Capsaicin (the chemical that makes stuff spicy) is not water soluble. Drinking water or soda actually just moves the capsaicin around your mouth, spreading it so it's affecting a larger area. Drink something with lots of fat such as milk, as capsaicin is fat soluble, so it will stick to the fat and go down to your tumm... |
The testicles are formed inside the abdominal cavity and then drop down prior to sexual maturity. There is a nerve attached to the testicle that runs back into that area. |
We get initially attracted by looks, for sure, but they aren't enough on their own for most people. Neither is personality, of course. It is oversimplifying to say looks aren't important. But it is also oversimplifying to say we are more attracted by looks. It's called "lying" and people do it to be polite. Those who h... |
A more sensitive and dense pattern of nerves and minute vascularisation in your face. Your back/thigh/arm doesn't have the same amount or type of nerves as your face. Your head is highly vascular as well, and is the warmest appendage from the core. You regulate your skull temperature quicker to keep your brain in its h... |
Totally. And it can wake you up out of a dead sleep. Reason? Any number of reasons, something tickling your nose, allergies, respiratory infections. |
They *do* hydrate the body. They contain caffeine which is a mild diuretic (makes you urinate) but overall they do hydrate. In general, they *do* hydrate you. Just less so than pure water, because caffeine is a diuretic (i.e. a chemical that makes you pee more than normal), so you urinate out more of the water content ... |
A lot of the tiredness comes from your posture. When we sit in front of a screen (or lay down in the same posture for a long time), our muscles strain and tense up. There needs to be movement in our muscles for proper blood flow. The strain in muscles is why we feel tired. It's mostly because you're not moving, not dri... |
You are incredibly mistaken on how easy it would be to make a soldier bulletproof. When you shoot someone they suffer bruised and/or broken ribs even with the hugeass vest and ceramic plates in it. This is assuming the bullet doesn't go through and cause them a really nasty injury if not death. The technology to make a... |
credit ratings aren't related to the government. it's a for-profit institution that benefits other for-profit institutions (lending banks). credit bureaus don't work for you the individual, they sell your rating to the banks. |
Bigger body. More places for blood. Blood needs oxygen. More breathing. Same goes for bigger muscle guys too. |
fish usually die because the chemistry of the water is significantly different. temperature, ph levels, ammonia, nitrate, nitrite levels, any other chemicals in the system. it's rarely a matter of mud vs clean. |
I haven't noticed that, but it's probably meant to make you think you're buying a premium product... All part of the marketing. Brands want to have a point of difference. If Kettle is the exact same as another brand, what reason do you have to buy Kettle? |
The rays, especially the ultraviolet ones, are breaking the bonds of the molecules of the colored compounds. So they lose their color. It is the more energetic photons, the higher frequency ones, which do this best. |
No advantage to the imperial. The changes are arithmetic only. The metric system being standardised in orders of magnitude makes it significantly easier to remember. It's worth pointing out they are (were?) both standardised. The difference is one is standardised in a much more user friendly way. Look at these two Impe... |
Gravity attracts heavier objects with more force than lighter objects. For example, if you drop a hammer in water, you will see the cheek sinking first, followed by the handle. That is because the cheek is made of steel and is more dense, therefore, heavier, than the handle, which is made of wood. The same thing is hap... |
Your retina has photoreceptors with specialized pigments which get modified by the inciding light. They change in conformation and affect nearby receptors, closing them and stopping a previously active influx of Na+ and Ca2+. Without the entrance of these positive ions, the cell membrane undergoes hyperpolarization (be... |
Because they cannot get to that position in the first place without being self serving, at least to some degree. Fully altruistic people never survive in politics long enough to get to any high ranks. Now there are a lot of politicians who have a large dose of altruism, but even these have problems getting to high rank... |
They are most likely using Uranium-Lead (U-Pb) dating. There is a mineral called zircon that incorporates uranium while forming, but rejects lead. It is assumed that all of the lead content in the zircon is from radioactive decay. The uranium, specifically U-238 (238 being the mass number for the specific isotope), und... |
This is called whole gut transit time and it varies from species to species. In humans it can take anywhere from 10-73 hours. This is very person specific and based on personal diet, activity and genetics. For instance, eating a large meal typically induces a bowl movement as your body is preparing for more digestion. ... |
Not sure how this is confusing. It means the animal doesn't have to come up to the surface to take another breath for that length of time. What exactly are you confused about? |
It's usually dehydration. When you go 9 hours or more without drinking water you become dehydrated regardless of whether you're awake or asleep. Try drinking a glass of water before you go to bed and keeping another full glass by your bed so you can drink if you wake up during the night. It could be one of a couple rea... |
Probably the same reason Vader didn't just force choke Obi-Wan or Luke. A person strong with the force would create a small aura around them, somewhat repelling others using a simple direct force ability on them. Like a bubble pushing against another bubble. For the same reason why you can Accio someone's wand, or can'... |
In principle, yes. But how many valid PINs exist at any time? Let's be very optimistic and guess 1 billion. There are 10 quadrillion possible 16-digit PINs, so you have a 1 in 10 million chance of guessing a valid PIN. That puts it in the same ballpark as guessing the winning lottery numbers, and there are probably far... |
Uber is growing under the same strategy and mentality as Amazon - grow as fast as possible, gain as much market share as possible and do so at any expense. In a new market like ride sharing, the biggest and most popular will win in the long run. Profitability may be quarters, if not years, away but the prospect of goin... |
$7 a day can feed multiple people quite easily here in the US, too. Go buy a giant bag of rice, and a few bags of dried beans. That can feed a single person for about $1 - $2 per day. Of course, you have money, and you're not starving, so you're not satisfied with just eating rice and beans. This depends heavily on the... |
A particular example: brown bears. If the bear doesn't get enough chow to get fat before hibernation, it's likely to wake up in the middle of the winter and go about looking for anything to eat. What you get is a шатун, a "rocker", which is willing to kill anything that gets in its way (including armed humans), and is ... |
Some metals produce volatile compounds when binding with oils from the human body, such as when they are handled. These can produce a taste or smell (the familiar taste of pennies for instance) even if the metal itself does not have much of either on its own. If I'm not mistaken, the smell of most metals is caused by t... |
Acne is predominantly triggered by hormonal imbalances. When you are stressed, your body produces excess stress hormones, such as adrenaline and cortisol. Just imagine your computer's available memory being your skin. In order for it to run smoothly, you don't want to clog it up by running a ton of unnecessary programs... |
Conceptually that is possible. However most of the time when we talk about "nuclear missiles" we are referring to the concept of an "ICBM" or intercontinental ballistic missile. That type of missile fires between continents which means that its most vulnerable time, when it it is first launching, happens deep inside th... |
Because it's caused by contractions of the diaphragm. The sudden intake or exhale of air causes it to be in short bursts. & nbsp; When your brain thinks something is funny, sends a bunch of happy hormones around your body. You diaphragm spasms, contracting your lungs, the expulsion of air causes you to need to breath, ... |
> Is it true? Does this improve the prognosis? Why?Is it true? Does this improve the prognosis? Why? No, it doesn't help them live. But what it can do is identify health threats which would otherwise be difficult to detect. Someone who has hit their head needs to remain awake because a brain bleed needs immediate atten... |
Major internet service providers are just like any corporation, they're out to make as much money as possible. They charge as much as they can for their product, and spend as little as possible on infrastructure. So, while prices have continued to go up, and new ways are introduced to place fees and fines on the users.... |
An LCD element is made so it is transparent unless you apply a voltage. When you apply a voltage to the element it is going black. It does not take much power to do this as you only need a voltage and no current. The electricity does not pass through the elements but still affects it. You can get window sized LCD eleme... |
Great question! Two important mechanisms: innervation and gate control theory. First, innervation. What's very different from the inside of the mouth and the tongue compared to skin elsewhere in the body (except the fingertips), is that its greatly sensorily innervated! This means it is much more sensitive to physical ... |
Most people I know are not okay with eating moldy cheese unless it's specifically cultured mold such as is found in blue cheese. Molds used in blue cheese are safe for human consumption and enhance the flavor, but they are a specific type of mold. The fuzzy stuff that eventually appears on both cheese and bread tastes ... |
Canada has a parliamentary system, and so they have a prime minister, who is elected from among the parties within parliament itself. In addition, their upper house (the Senate, equivalent to the House of Lords in the UK) is appointed by the government, rather than elected by the population. In addition, like many parl... |
Part of it might be the fact that your friend in amazing shape - muscle is considerably more dense than fat, and sinks while fat floats. Humans have a breath holding instinct annnnd that's it. Swimming and floating (the latter being kind of a beginners version of the former) are learned skills for us. Despite the aquat... |
The first commentor has it spot on but I would definitely like to double down on the notion that the science is young. It definitely is, we learn new things every day. When it comes to our bodies there is still a lot we don't know and sometimes we find out that certain cells interact with certain things in ways we didn... |
In the original series the stardates were made up just to sound futuristic. There have been some attempts to explain them, but the original writers didn't have a secret code. Starting with The Next Generation, they standardized them. The first number (4) represented the four in 24th century. The second number was the s... |
It's called [cute aggression]( URL_1 ) and it's due to [crossed 'wires' in your brain trying to handle the extreme emotional response]( URL_0 ) to cuteness. In my culture it's pretty common for people to say "He/she is so cute that I want to kick them in the face!" Edit: Since everyone is itching to know what I am, sou... |
Doctor here. Essentially when you lie on one particular side, you put pressure on bony prominences, and this pressure, actually makes it more difficult for blood to penetrate the skin on the pressure areas. That feeling is essentially your body telling you that your tissues under pressure are suffocating. You then inst... |
