The classic "runner's stitch" is from the diaphragm fatiguing and cramping from too much stress. With running this is obviously due to the increases in breathing due to the exertion. If you are over stressing the diaphragm when you are eating then you are doing something terribly wrong and need to cut back on engorging... |
Yes. Essentially, the data transferred is just a stream of 1s and 0s for the destination drive to write (it's probably encrypted, and it has some extra stuff around it to make sure that the data reaches the destination computer intact). The bottleneck depends on a) the destination drive's write speed and b) the WiFi sp... |
It's usually due to the amount of data the camera can move from its sensor into its memory. Imagine a basketball hoop: you can only fit through a single basket ball at the time, but but you would be able to push through a lot of tennis balls, because they are smaller. With higher frame rate, the frames resolution needs... |
The hippocampus and the frontal cortex are two large ares in the brain associated with memory and the take in a great deal of imformation every minute. Retrieving it is not always easy. It doesn't simply come when you ask it to. Music helps because it provides a rhythm and rhyme and sometimes alliteration which helps t... |
It's definitely possible. It's a known side effect of the pink pigment in Krill, Astaxanthin. But the specifics (e.g. how much you need to eat and how visible it will be) are going to vary from person to person. If you're looking to change your skin color with your diet, [ URL_0 ](it may be easier to do it with carrots... |
[citing a article from a Google search]( URL_0 ), the range is in the order of dozens of terabytes for a older Pixar movie, or hundreds or more for recent productions. |
It depends on the glue. PVC glue actually melts the PVC that you apply it to and then the two melted sections that you're gluing harden and form together into a solid joint. Cyanoacrylate (superglue) reacts with water in the air to form a polymer. Since this polymer started as a liquid it can seep into the many nooks a... |
The waves travel at the same speed, but as you move further away from the router, the strength of the signal decreases, and becomes more prone to interference from other sources. When this happens, it becomes harder for your computer to determine what's part of the signal, and what's part of the environmental interfere... |
So c only applies to things in space, not space itself. Space itself can, and did, expand much faster than c during its early formation. That's the reason the observable universe is smaller than the universe as a whole: anything beyond the observable universe is moving away from us at faster than c, meaning light emitt... |
That depends what you're asking. For only weight loss or gain, food quality doesn't really matter. Your body uses energy to live every day, which we normally measure in calories. You supply that energy through eating and drinking. If you eat more calories in food than your body uses, it will be stored as fat. If you ea... |
Software developer here, > but why aren't then virtually bug free by now? We haven't been working on the same programs this whole time. Every time you change an existing code base, you no longer have the same program. Business people assume software is more malleable than it is, and they are loathe to throw away IP. So... |
Water is a better conductor of heat than air. If there's any convection, where the water is moving about you, it only accelerates the process, as cold water that takes your heat and warms up moves out of the way for other, colder water to do the same. Body heat is lost through water faster than it is through the air. I... |
It's only a matter of time until somebody brings in bedbugs, and then they have to fumigate the building. |
If you attempted to deposit 1T by personal cheque, they would tell you they can not accept it due to its high probability of bouncing. If you attempted to deposit 1T in cash, the police would be called and you'd have some serious explaining to do as to how you came about the money. If you attempted to deposit 1T as an ... |
This is a philosophical question as no one knows the answer. As you can feel "happiness" there must be something real to it. And there also must be something more than chemicals and hormones that produce genuine happiness as it can be observed that substances that produce "happiness" used long term often lead to depres... |
We could certainly put a base on the Moon, and it could even potentially have significant use, such as a place from which to launch further exploration without having to fight against earth's gravity. but it's a more hostile environment, and some questions we have, such as the search for extraterrestrial life, are much... |
Nature. But for a long time it was more or less balanced, and then we came in and pushed on the scales, adding more CO2 into the environment than naturally gets removed, while at the same time are contributing in removing the things in the cycle that removes the CO2 from the air. Nature. Humans are reported to add abou... |
It's controlled by our brains, including parts of the brain associated with physical/motion control, which we don't consciously think about and can't 100% control without practice. This is similar to how we naturally walk a bit different from other people, we can control our gait but usually don't think about it. Our b... |
You charge things to the card during the month. At the end of the month the bill comes. There will be a minimum amount due to keep the account in good standing. If you don't pay the full amount, you will be charged interest on the remaining balance. You can pay it off fully and still build credit. |
Interesting point, Europe's rivers were so polluted when the New World was discovered they would not drink the water from the American rivers and streams - Also why beer was so common, they did not understand disease, but boiling the water - sterilized it, and making the beer probably covered up a lot of bad tastes, ev... |
Usually a major motivator in BSD is licensing. It's a unix environment that performs comparably well to Linux (better in a few regards) but doesn't have some of the rules with the GNU license. Basically, you can tweak it and don't have to release the source code. Big companies like to not release the source code for th... |
I doubt it. Most fluoride therapy compounds for strengthening tooth enamel are found in toothpaste in rather dilute amounts ( > 0.5% by mass). Compounded with that, if you brush like a normal person, you only you around a pea-sized amount each time anyway, and furthermore, you probably spit it out and then wash out the... |
Start with the simplest form of it. [here]( URL_0 ). T*_ab_* is the stress-energy tensor. It contains things like energy, momentum, and pressure. G*_ab_* is the Einstein tensor. It's related to the curvature of spacetime. 8piG/c^(4) is just a unit conversion factor; you can choose to use units where this constant is eq... |
It's selling porn. That's it. Those sketchy links you end up getting sent by a tinder bot or anything else are just porn. The one reaping the benefit is the person selling the porn. |
Your browser doesn't know! For the second question: Your browser sends the request to your proxy, which is maintained by your Internet Service Provider (they're the people you pay money to for your internet). Your proxy knows of the existence of a Domain Name System Server (DNS) that it sends the name to. If you want t... |
Pills don't know anything. Your take medicine and your body will absorb it. It may be absorbed into the blood and travel all around your body. If you take a pain reliever, it is not targeting your headache but is dispersed through the whole body. The only noticeable change is that the pain goes away in the place that h... |
Because endurance isn't like a battery in an electric car with a set capacity. Aerobic stamina is the ability to replenish the oxygen and energy your muscles use while you're burning it. A closer comparison is a regular car, that can run as long as it has gas, but will stall unless it gets enough air as well. Running a... |
Because of the camera's field of view (FOV). If you're a big first person shooter game player (or you know about cameras) you're probably familar with FOV. If we consider what we can see as a cone starting at our eye and expanding out like [this]( URL_1 ) then FOV is the angle between the two boundary lines. In shooter... |
Horses are absolutely awesome for crowd control. They're big, meaty bulldozers that can and will just knock people down. They also give mounted officers an elevated position that allows them to see over people and maintain good situational awareness. Horses also have a pretty good intimidation factor. Even drunk morons... |
A normal function of emotion is to enhance memory in order to improve recall of experiences that have importance or relevance for our survival. Emotion acts like a highlighter pen that emphasizes certain aspects of experiences to make them more memorable. Memory formation involves registering information (encoding), pr... |
Originally we couldn't, you can measure electronic charge, and with some effort the number of electrons, modern but early efforts at building a periodic table got very confused because lots of elements have the same number of electrons. That, as you might imagine, didn't work very well, but everyone knew it didn't work... |
Skin is the largest organ, it also heals itself. Sorry that this is not an answer to your question just more of another interesting fact, and I didn't mean to come across rude. It can't fulfill its function without healing. The liver removes toxins from the blood by absorbing them into its cells, which then die and get... |
Linguist here: good question! It's because FLA (first language acquisition) isn't rote learning, i.e. Kids don't just hear sentences and words and repeat them. They are learning **patterns and structures**, constantly forming hypotheses based on what they hear (even if no one talks directly to them!) and testing them o... |
Vodka is not an aged drink. Wine gains flavor from allowing the organic molecules react over time. They form different, more subtle flavors as they age. Whiskey is much more alcoholic, and aging alone doesn't do much. However, they're aged in wood barrels (depends on type of whiskey to determine age and barrel types), ... |
I used to live near an industrial sized bread bakery/manufacturer. Every night would smell like freshly baked bread. Perhaps you are getting smells from different businesses nearby which work on different schedules. Perhaps not something as recognizable as bread. Two sides to this; whatever you're smelling is changing,... |
Trains are difficult to stop. The horns are really loud to bring awareness to their presence. It's easier for a car or a pedestrian to move out of the way than it would be for the train to make an emergency stop. Many years ago, I worked at a factory that used trains to move things around the plant. To get to my office... |
Our eyes need to focus separately for the same reason a camera does, and not because we see in 3d. Here's a simple experiment: close one eye and hold a finger right in front of the other eye. See how you focus on the finger and the background becomes blurry? Alternatively, focus on the background and the finger becomes... |
Inside, without a doubt. I had a bomber jacket from WWII (like, one actually worn by a member of the Army Air Corp on a bomber over Germany and the Pacific), and it was made of a single layer of sheepskin, with the fleece on the inside. The skin side stops the wind, the fleece side traps pockets of air against your bod... |
There are F2P that can be also Pay to Win (RPGs, MMORPGS). Others are pretty fair and they make their money out of skins or extras (like MOBAs). In the case of P2W, You can beat the game with the standard items, you just need more effort compared to if you got some premium items. So they make the games harder in that w... |
Who said they don't know where he is? They just can't touch him. What are they going to do, send a SEAL team into a government building in the middle of Moscow? The diplomatic repecussions would be enormous, and I wouldn't be surprised if Russia retaliated by assassinating a government official on US soil. The relation... |
Let's imagine two characters; Bob the Barbarian and Will the Wizard. Bob is very strong and very tough, but not a very smart or sociable guy. Will is very smart and can do cool magic things, but is a frail fellow. You get to come up with a fun story for Bob and/or Will about why they're an adventurer/how they got to be... |
When you sleep, that means ~8 hours of you not watching the snow accumulate. So it seems like OMG sudden snow. When it happens during the day, you see it grow gradually. Night is longer in the winter, so depending on where you live it can be significantly more likely to snow at night. But most of it's that it's six to ... |
I just invented transporters like on Star Trek. The problem is that the technology needs to use the radio spectrum currently being used by AM radio channels. So, a decision needs to be made. Which benefits society more? AM radio? Or being able to magically transport goods and people from one point on the planet to anot... |
Oil is used to produce some 70,000 different chemicals and synthetic materials, so until we find a way to produce each of those things without oil, then it will never be obsolete. We're not talking about silly things either, oil is an essential material for making plastic, nylon, and a thousand other synthetic fibers. ... |
The cells in the meat you eat are not alive, so it doesn't matter if they are damaged when they freeze. They're already damaged beyond repair from lack of oxygen. That does however not mean that they've lost their nutritional value. Even if you crush an egg, all the nutritients are still there, right? Assuming you don'... |
Light *does* fade with distance! You can see this quite clearly - light sources further from us are much dimmer than those which are closer. The intensity of light decreases with the square of the distance ( I ~ 1/r^2), just as sound waves do. This is the inverse square law, and it comes up in lots of other places in p... |
There are two things that go into why a material can have a mirror finish. First, is whether light that hits it reflects straight back or gets scattered in many different directions. Smooth surfaces scatter less of the reflected light, and will be shinier than rough surfaces. Any material can be polished.* Polishing is... |
Because they're usually staffed by volunteers and if people's ability to travel is reduced things that are unnecessary to them are the first to go. |
With video files there are 3 different format types to consider: * The video codec. This is how it transforms the video frames in the file into something you can actually see on screen. H264 is a video codec, its a method of compressing and decompressing video data. * The audio codec. Equivalent of the video codec, but... |
The graph shows the inflation rate - how fast prices are rising - and not the actual price itself. The Euro has maintained low to normal inflation since it started, currently sitting at 2% and never above 3% in the last five years. That is thanks to deliberate policy by the European Central Bank. Many other central ban... |
To make a modern analogy: God is the Developer of an MMO. He notices his players are misbehaving, and logs into the game as Jesus. He travels around as Jesus talking to people and preaching. He then gets lynched and killed by trolls. God resurrects Jesus and walks around talking a bit more, then ascends him out of the ... |
some dust can be very dangerous, for example if you're doing renovations or construction and end up pulverizing cement, you should wear a mask because the dust fucks up your lungs. but regular household dust is harmless, it just looks bad In a household setting, removing dust can generally be seen as aesthetic maintena... |
We consider dark web like beeing a part of the internet who required an encrypted connection where users are anonymized.

Most of the US Debt is owned by entities within the US, either private citizens, or other parts of the US government. It is not a single debt but rather numerous different debts owed by different entities to different entities. Payments are made by the revenue the US government raises, such as through taxes. While the ... |
around here (northeast US), double flashing can mean anything from "your headlights aren't on", "your trunk is open", or "you have the right of way, please go ahead of me". it's just a non-agressive way to signal to other drivers that they should pay attention or take some kind of action. It's a [Schelling point]( URL_... |
I can't believe the answers you're getting. It's all in the physics, not about honor at all. Up until the civil war most soldiers used muskets. Muskets were smoothbore guns which had a practical range of a hundred yards at most. Most of the time they were fired at a range of fifty yards because they were so inaccurate.... |
The gasoline supplies only the carbon (C), the oxygen (O2) comes from the atmosphere. Carbon weighs 12 grams per mole, oxygen weighs 16 grams per mole, so for every kilogram of carbon you need 2.67 kilograms of oxygen. The carbon content of gasoline depends on which molecules are in it; if we assume pure octane (C8H18)... |
Shrubs and trees are both specifically *woody* plants with stems that survive throughput the winter. A tree has a clear central trunk whereas a shrub has multiple stems rising from the ground. 'Bush' is a more general term for any plant with multiple stems rising from the ground, and that can be either woody or what's ... |
My brain: "Did I lock the front door?" I don't know about you but I seem to recall everything in my life that I even slightly regret. To put it simply, nerves in your eyes let your brain know that light levels are decreasing. This causes a part of your brain to release melatonin. This "disconnects" parts of your brain ... |
Because while it's 34 degrees on the ground, it's colder a few thousand feet up, and that's where the snow forms. Get ready to have your mind blown - in most cases rain starts out as snow or hail, and then melts on the way down. If the air isn't warm enough to finish the melting process, it's snow when it lands. Someti... |
According to my 10 year old, who hates showers: - Before getting in the shower he's all nice, warm, clothed, and happy. - Stripping this clothes off makes him cold, and embarrassed so he hates doing it. - Once he's in the shower he warms back up again due to the warm water and it feels nice. - However once he's all war... |
Not gauges, baffles. [Capillary action]( URL_0 ) keeps the ink within the 'loading area' as I call it in the same way wax stays within a candle's wick. The majority of the ink in the pen is free-flowing in the tank, but the loading area keeps it more or less locked in there and feeds to the ballpoint at a regular rate.... |
Well there's a few ideas.. Your moving your phone around more when it's being charged so the charger is having to bend much more often. Your phone chargers is also going to be less bulky because the charging port is smaller. No ones going to design a charging cable where the wire is bigger than the port. I go through p... |
You can't take images you don't have a right to use, put them on something, and then sell it.

Babies build immunity and tolerance against things as they grow. Vaccines act as barriers to things a baby's body can't fight off yet (pertussis, chicken pox, measles), but there aren't vaccines for allergies. If a child is regularly exposed to dairy from a young age, most of the time, a child's body learns to digest t... |
*In science, 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent.' I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms. -- Stephen Jay Gould* Typically in science, once we pass that factual threshol... |
A towel consists of woven string. The string consists of small fibers. Those fibers have gaps in them, which get there by twisting and weaving. When you put a towel in water, water gets "sucked" into the gaps of the string. This happens due to the capillary effect. When all of the air-gaps are filled with water, then t... |
I'll quote an answer from when this was asked previously: > The threshold for "too much light" is determined by the brain for both eyes combined, not individually. That's why if you only open one eye, the brain doesn't think it is too bright, as it effectively uses the total amount of light from both eyes to check. BTW... |
Essentially it works the same way. [Here's]( URL_2 ) a paper by the people behind Shazam where they detail a part of their method. By taking small snippets of waveforms and frequencies, they can compare them to every song in their database with similar waveforms and frequencies. For example, if you're humming the star ... |
Some mail goes by registered post which means the chain of custody is properly tracked. To terminate this chain of custody they require someone to sign for it so that they have proof of delivery. This costs more so often packages that are either low value or not important aren't tracked. You don't have to sign when the... |
WiFi isn't going to hurt you. The heat from the laptop though, most certainly can.

They handed out mortgages to everyone they could. At the time, just about anyone could get approved for a huge mortgage. Then, they would take 1000 mortgages (usually ones they shouldn't have given out) and packaged it together in a 'derivative'. They could then sell this derivative to unsuspecting investors. Basically... |
Society has changed. A hundred years ago the country was far less populated and people were needed for every task. There were more jobs than people. Nowadays there are far more people and, with the advent of automation and globalization, far fewer jobs. This creates a resentment among those who're competing for jobs th... |
There are a couple of ways. You could have a switchover to battery power which takes 10 milliseconds or so and cover the gap with capacitors. Or you could have incoming AC converted to a DC line on which the battery resides, then back to AC for output. In that case the battery is *always* on the line and there isn't an... |
First, remember how we 'see' color. Light of all colors hits a surface, and some of the light is absorbed, and some is reflected. We only see the *reflected* light. So something 'red' is taking away the green and blue light, but not the red light. Therefore, the pigments in oil paints do not 'add color', they actually ... |
Continents move ***INCREDIBLY*** slow. Like 2 to 5 centimeters a year. there's more than enough give and wiggle to the cables that this is a nonissue.

A couple of reasons: > 1. It costs more to get matte finish cars. At least $1000 (Hyundai), and typically closer to $3000 (BMW) and as much as $4000 (Mercedes).

I think the best description of alcohol's effect is lowering inhibitions.

Salmonella bacteria are living creatures and need to feed. If you get some on fabric, it's only going to live about four hours without any food. Chances are it will die off in your hamper. Other pathogens, like norovirus, can live much longer on fabrics. |
It's a blast from the past! In the olden days, before switched Ethernet, all devices were connected to a single coax cable. The Ethernet specs say that the maximum length is X meters and the signal needs to arrive on all stations within N microseconds. Everything which the signal passes through adds delay: The signal n... |
The main advantage is that 2 and 3 are factors of twelve. That means that 1/2, 1/3, 1/4, 1/6, 1/8, and 1/9 can all be expressed with a finite number of "decimal" digits. It also means if you have "10" dollars, it can be split evenly 2, 3, 4, or 6 ways. By comparison, in base 10, only 1/2, 1/4, 1/5, and 1/8 have a finit... |
Because you've been lying down and not swallowing, the extra thick mucus your nose is producing during your cold has been dripping down your throat all night and irritating the crap out of it.

In vino Veritas. In wine, there is truth. When you're drunk, you are your true self, stripped of your inhibitions, the mask you wear for society, and of your rational self. You likely really do miss your ex, but your rational brain is telling you that you don't. |
Not really. It's happening far, far, far faster than it ever has before (because humans).

Hard to exactly say without audio examples (which I do not have). Distortion can create a range of tones, depending on specific pedals, or effects used.
