The simple answer is stress causes this. By setting a schedule your body will fall into a rhythm. After a while you don't really need the alarm at all. However as we know our natural rythems get disturbed occasionally. When we must get up we are creating stress that is easiest to avoid by doing nothing and that is what...
There's a civil war going on in Yemen, with 3 main sides. * Houthis - largest minority ethnic group in the country. They're allies of the former President. Proxy force of Iran. Don't like the Yemeni government because it's friendly with Saudi Arabia and doesn't give them enough say in politics * Government - Allied/pro...
Actually, this is a good neuroscientific, meaty question. Well done!! Our memories are stored as series of hierarchically arranged and organized associations. The reason we know this is when we make a word mistake, such as want to say "world" and say work, or "word" instead. Most all mistakes verbally are of this kind....
Motels have doors which open directly to the parking lot. Hotels have rooms which open into a shared hallway. Generally, hotels will offer more and better accommodations than motels, but that is not always the case. I have stayed in hotels that didn't offer anything but a room with a bed. A 'motel' is a 'motor hotel'. ...
Water doesn't expire. It's the bottle that expires, because the plastic that makes up the bottle breaks down. Laws in countries ask that every single food and drink item have an expiration date. It's a formality that needs to be followed. Water doesn't really expire. Some guys wrote about bottles too, and yea that's a ...
No. First there's the high transportation cost. Then there's the fact that it doesn't just "disappear" as harmful chemicals and pollutants are released into the atmosphere. It's really not much different than incinerating garbage locally just with a much higher transportation cost. Trash isn't a significant space probl...
Videos like this are scams. They either want to sell you something, or more likely, they just hide a battery somewhere in there and get ~19M youtube views with very little effort. Try to make one yourself and you'll see that they do not work. Conservation of energy is a tough principle to violate. You can't generate en...
A ton of factors contribute. In my opinion, the ability to project is what best determines a powerful voice. Ever watch Sister Act? Whoopi puts her hand on the young soprano's diaphragm and the tremulous becomes clear and strong.
Scientists have started to zero in on the way the brain stores and encodes information, called sparse distributed representation. This encoding mechanism is in fact digital. Large groupings of neuronal columns and micro-columns connected to sensory pathways are activated sparsely, and unique clusters of connected activ...
The way Fortune took the numbers from oecd and converted it to hours per week is not taking holidays out of the calculation. They simply divided the number by 52. According to a slightly older article from the FAZ, Germans were working 41.1 hours per week on average: URL_0 There might have been a rise of very short par...
It's not that the medal of freedom is exclusive to civilians, it's that there are other medals (such as the medal of honor) which a civilian can't receive. So the medal of freedom is the highest honor which can be given to a civilian, though it can be given to other people too. > Or is my definition of civilian incorre...
Rivers tend to form in places that have a long, continuous, mostly-gradual path from high to low places. This is exactly the sort of path trains need, as they cannot climb (or safely descend) very steep slopes. Some rivers do have steep bits (rapids, waterfalls), and in these bits the train will of course take a differ...
The air conditioner has a motor which compresses the gas hence it is called the compressor. If you start the compressor after a period of being off then the electric motor, the compressor, starts against no load. It does not begin pumping against a compressed gas. It is easier for a motor to start against no load. If t...
I make no claims to be an expert on this but I have seen articles where they tested the theory about "time flies when you're having fun"... Basically they say that the concept of time, especially inside our squishy brains is fluid and ever changing based on activity level, dopamine, etc. So I would go out on a limb and...
The "new" organ is the mesentery, which has been known about for many years (it was in my medical terminology classes years ago). What's new is they decided it's *structure* is continuous enough to be it's own organ, as opposed to being a feature of another organ (the colon)
Jesus what class is this? Sorry I can't really help; I'm as lost as you
If they have nothing whatsoever to eat, then the fat guy might live a little longer, but not that much longer, because vitamin deficiency will kill him long before his fat reserves are expended. If they get vitamin supplements to prevent that, then the fat guy would live much, much longer than the skinny guy. This is t...
At least partially it's due to economic pressures. As the old media lost the methods of revenue gathering - newspapers stopped selling, TV in its pure form is on its way out - they decided to adopt the methods of the new media that was sweeping over Facebook and Twitter. Higher response speed, clickbaity titles, listic...
You could look at a city's budget and see how much they collected in business taxes last year. Then take that number and divide it by 365 to get the average taxes per day. Finally you can divide that number by the business tax rate for the area to get the total business profits for a typical day in the city. That will ...
Your battery app calculates the remaining battery based on the battery power currently being used (mV) and your usage since it was fully charged. That's why you can generally do calibration to correctly measure the current battery status and range of it. Usually, if we ignore very little variations in the battery power...
First of all, please ignore the other responses here as they are all guesses. Do NOT go get a corrective surgery or anything like that because breathing through one nostril is very normal. Your nasal passages go through what is called the nasal cycle. Basically throughout the day, your autonomous nervous system (what c...
It's probably not the capacitor, it's the transformer. Older cameras generate a high voltage to get a bright flash, and that voltage is generated through a transformer/capacitor circuit. The whining is caused by [magnetostriction]( URL_0 ). As the magnetic field rapidly changes in the transformer, the materials expand ...
It's based on you experiences you have had with these genres. For example, I used to listen to the most annoying alarm clock every morning because it was the only thing loud enough to wake me. One day I was walking through a store and heard a sound with the same frequency going over the PA and immediately felt angry ab...
In starcraft, each unit has a "counter-unit". At the highest difficulty, an AI will likely have one of its workers or cheap units in your base, watching your build, while simultaneously building the counter to what you have. This is how it decides upon the macro side of the game. For the micro (individual skirmishes or...
Some of it is because your purchasing power is relative to the cost of living where you are.
They get stretched out, and can separate, causing diastasis recti. Not everyone experiences this condition, and many times the muscles just go back to normal. Your ligaments and joints get loose as well, all caused by certain pregnancy hormones that enable a women's hips to shift during birth. All of this usually goes ...
First off, Putin has acted in ways more akin to the Soviets during the Cold war than any leader since the fall of the USSR, such as invading Ukraine, having opposition politicians and journalists killed. Secondly, the evidence suggest it's not about being best friends or equal super powers with them, but Russia gaining...
Two things. First, we don't only exxhale CO2. Each breath is about 4-5% CO2. So blowing on the fire does send some oxygen than way directly. Blowing also clears out the dead air in the fire (CO2 being heavier) allowing normal air to replace it. The difference in CO2 between inhaled and exhaled breath is surprisingly sm...
It's sales and adoption have been terrible. The original Wii was released in late 2006. By 2010, it had 70 million worldwide sales of the console. Source - URL_0 In comparison, the Wii U has been out since 2012, and in the same time period only has 14 million units shipped. Compare that with its competition like the Xb...
The water pressure in your pipes is due to gravity pulling the water down from the water tower; there's no extra pumps to give you water pressure. Once the water is pumped up into the tower, that stores the energy to push the water out of your water taps. So, since it's gravity pushing down, a water tower can't push wa...
Your body can only sense temperature differences, not actual temperature. For example, if you put your left hand in ice water and your right hand in warm water for a while, then dip both hands in lukewarm water, your left hand will feel hot while your right hand will feel cold even though they are feeling the same temp...
When you haven't been told how to think about life yet and all you think about is the interpretation of your situation creativity tends to much easier. Adults are bound by the limits of what they believe is possible and tend to think within that box of reality. Children are able to think outside of the box without feel...
Nuggets, Chicken-based sausage products, stuff like that. The meat is almost always ground up so it has a consistent texture. You can use ground chicken in a product and still call it 100% chicken, cause it is, but in order to say 100% chicken *breast* it better be breast meat. [Russia]( URL_1 ). Seriously, for many ye...
they don't. chameleons change to fit their mood. they don't change to camouflage. on other hand, animals like cuttlefish and flounder, use their eyes to see what to colors and patterns to change to
Do you know what the word "omniferous" means? It means "bearing many things". Have you ever seen or heard that word before? I'm going to assume you haven't. Do you know how to say it? Even though you've never heard it pronounced? Of course you do. They know how to read music, just like you know how to read letters. **E...
The phrase “paint the town red” most likely owes its origin to one legendary night of drunkenness. In 1837, the Marquis of Waterford—a known lush and mischief maker—led a group of friends on a night of drinking through the English town of Melton Mowbray. The bender culminated in vandalism after Waterford and his fellow...
when you look at a number like 4,367, what you're really looking at is the sum: 4(1000) + 3(100) + 6(10) + 7(1) which is a **power series**: 4(10^(3)) + 3(10^(2)) + 6(10^(1)) + 7(10^(0)) That is, each "digit" corresponds to a **power** of 10. It's actually a sum of infinitely many terms, where all but finitely many hav...
Totally winging this, but I'm guessing it just wasn't diagnosed much before reading small text became a part of daily life. If you learned to read when younger but need bifocals at 40, who cares if you already know everything you need to know? Because being outside prevents nearsightedness. Children spend more time ind...
Geologically Europe and Asia are a single continent referred to as "Eurasia", Europe and Asia as two separate entities is a cultural and political divide more than anything. Like many things in life, this geographical untidiness was the result of clever people operating with incomplete information. The Ancient Greeks w...
Most people are weak, directionless and crave "group-belonging" no matter how bad it is. Non-mob-mentality is only ever for a small number of people who are just flat out smarter people. Have you ever seen a swarm of birds, fish, insects, really any massive group of animals? They function as one at least somewhat cohes...
You have Tinnitus, my friend. It is one of the least debilitating diseases in the world, so don't worry. It only means that when it's quiet you may hear a high-pitched sound.
They get permits for filming. Some of them are just warehouses and houses and other locations just made up to look like wherever the scene is supposed to be taking place, others - like the beach for example is taking place on a beach, just the movie makers have the permit to film there and it's cleared out. Remember Po...
The way muscles are developed in mammals isn't the only way to produce movement in an organism. Often evolution will find more than one way to do something. There are many different kinds of locomotion like flagellum, or even pumping water around to stiffen or relax. So while they have muscles, they aren't necessarily ...
Because it's actually cheaper to make processed food. Processed food doesn't go bad as fast as non-processed because processed food is full of preservatives and chemicals. Pepsi is made of water, corn syrup, food coloring and carbon dioxide of which all are plentiful and cheap. Fresh oange juice is made from a fruit an...
[Here's an animation I did to explain sine and cosine]( URL_1 ). This is the main idea behind 90% of what you'll learn in trigonometry. Pick a unit circle. Move a dot around that circle at an angle & theta;, shown there in yellow. The sine of that angle in yellow is the vertical position of the point on the circle. The...
They are very different. Normal fatigue from working out is caused by lactic acid, a compound produced by your muscles when they run out of oxygen. Lactic acid is a byproduct of breaking down carbohydrates for energy that has the unfortunate side effect of making your muscles feel sore, but it doesn't physically damage...
Well the biggest one is that humans require water for almost every bodily function, so by drinking water we prevent dying. Humans are around 60% water. Water is used in every cellular function and reaction. We lose water continuously through everything we do (sweat, urine). It continuously needs to be replenished for u...
the deadline is Jan 31st. there's no reason to send them out early. so if it's a mature payroll department, and they know it takes them 2 weeks to do it, there's no reason to start them Jan 1st because they got other things to do. So I prepare payroll reports and have to do them quarterly. There is also Year end report...
Its Soemtimes easy to forget how much of a skill drawing really I is. This is similar to asking, why can't we all make shots in a basketball hoop because we can picture it in our heads. Muscle memory and building skill If someone gave you a pencil and asked you to sketch their face, you could probably get the outline, ...
Julian Assange, and a collective of anonymous others. No one stops them because they do not "exist" in any real location, aside from Assange, who is taking refuge in an embassy in Europe. He recently did an IAMA on reddit, and gets talked about a lot.
The Marshall Plan, and a cultural commitment to education. After WW2, the US committed to rebuilding West Germany from the ground up, probably for Cold War propaganda reasons as much as altruistic reasons. Billions of dollars poured in to get West Germany's infrastructure back up to pre war levels. The German populatio...
I'm not entirely sure, but I'd guess its similar to why people with arthritis can tell when a storm is coming hours or days before. The changing pressure in the atmosphere (caused by an approaching cold front or storm) interacts with the pressure in their bones and tendons and somehow makes them more sensitive to pain....
Your immersing the wound into a hypertonic environment(high salinity) which will then cause your cells to move water toward the solution. This Hydrates the wound while also killing bacteria due to the salinity, speeding up the healing process. That's about all I got off the top of my head. People are talking about anti...
In the simplest way it's because they broke your rights, typically either legally or your constitution, and if we allowed cops to break these rules for evidence that defeats their purpose in the first place. 2 main reasons why. The first is that any evidence illegal seized is can be viewed as planted. Everyone is innoc...
*"Necessity is the mother of invention..."* Most criminals start small, very few go in for the big jobs straight off, and even then they usually only have small roles to play if they do. Simple skills like picking locks and pockets just take a little practice, and most people can be reasonably successful in a short per...
Not particularily alarming yet. > How is it possible to ever pay that off? Remember, this is soveriegn debt. It's not like a loan you'd take from a bank. In fact, the idea of a national bank and sovereign debt was partly created to alleviate the catastrophic borrowing some monarchs did. So for one, while you'd go to a ...
Kinda, we can work with Recombinant DNA to insert certain genes on certain cells so they produce a protein that they are not producing, but should. One example would be getting pancreatic cells to produce insunline on a diabetic patient. [I'll leave you this video]( URL_0 )
When you apply/sign up for it you generally give them rights to access your medical records. They can basically get records from any doctor you have seen. And if they find out you didn't disclose something in the first place then they will just deny your claims.
That's very much an American thing. Want to see Americans freak out? Go to a European vehicle rental counter. The shifter on my 2015 Grand Cherokee, "looks" normal, but is really just a huge toggle switch, when you "flip it", the PRNDL indicator on the dash moves in the selected direction. There's a slight delay and I ...
Current is in the opposite direction of how the charges are actually "moving" due to historical reasons. When Franklin and others were first formalizing an organized set of laws for circuits, they assumed that the positive charge (arbitrarily named so) moved. Well, they were wrong. Electrons are the particles that "mov...
Couple of things here. First is us. We got there first and we have created enormous pressure on other species. Second is time. They could be doing exactly this but be a million years behind us - the blink of an eye for evolution. 1) All the primates are known to use tools. At least to some degree. 2) Why do you think e...
Imagine a classroom with three rows of seats. Suppose for example, that there are 3 students in the first row, 5 in the second and 6 in the third. This is called a distribution, one of students into rows of a classroom. We do the same with particles and how they arrange themselves into various states in a system. Typic...
It's awesome if you don't have to go to work or school.or have obligations. Once me and my friends went geocaching in the woods while staying up for 3 days straight only going back to my house to eat and drink.
What is toast bread? As far as I know there is only bread. Once it's toasted then you have toast. Or are there specific breads that are meant for toasting and I missed the memo. I understand your question. In lots of places in Europe, they have their usual bread, which most of North America would see as fancy bakery br...
Skeletal muscles move bones by pulling on them. Because we control this movement, they are called voluntary muscles. Muscles can pull but not push, so skeletal muscles are often arranged in pairs that pull bones in opposite directions.
Regarding healthy and unhealthy fats: generally speaking: the membranes of your cells always feflect the stuff you eat. Of course the body has its own fattyacid metabolism and can contribute here. but regarding the fats the general rule applies: you are what you eat. On the other hand: the milk you produce contains sti...
Rural farmer types tend to vote right, working class union members tend to vote left, Jews in Miami tend to vote left, poor black inner city folks tend to vote overwhelmingly left. Your statement doesn't really apply because education and income are too broad of factors to generalize how they will vote. Got to get more...
No. You wouldn't be saved from eating immediately before. Your body needs to metabolize the food into your blood which isn't instant. Not only that, if you're on the brink of starvation, then your digestive system wouldn't be functioning ideally; after all, starving to death takes typically over a month (assuming you'r...
Its basically pure sugar, so any mold or bacteria that touch it die because the concentration of sugar outside their cells causes water to leave them by osmosis and they shrivel and die. There are a lot of answers here that *answer* the question but not to a satisfying level of detail so I'll take a swing. The main rea...
Generally for when you're showing off your custom sound (doors and trunk open) you can control everything without actually having to be in the car. This can be great for subwoofer competitions, where the noise level in and around the car can be harmful to your hearing. It also can add a level of "cool" or enchance the ...
Black does not necessarily absorb heat the best. It absorbs light best. The color of different materials comes from what colors they absorb and what colors they reflect. White reflecting all visible colors and black absorbing all visible colors. The color spectrum extends in both ends. Heat at the temperatures you woul...
Hi, medical student here! The two classic things most people think of when stethoscopes are mentioned are listening to the heart and lungs so I'll address these. But they can also be used to listen to arteries and the intestines. What the stethoscope does is amplify vibrations. Things moving underneath the skin cause t...
Think of white light being made up of all the colors of the rainbow equally. Since light from our Sun is essentially white, and our moon is dark grey (ie: no color), it reflects light back to us without any colors of light "lost". So it looks white. (To prove this to yourself, try shining a white-light flashlight on a ...
It should be note that both terms (the Machiavellian more than the Bismarckian one) are usually used today to describe something that is often quite different from what those two people actually did and wrote about. Machiavellian has often a sort of evil undertone is basically used as a catchall term for any sort of "e...
The law of scarcity. The more expensive something is to produce (rare or limited quantities due to cost), the more valuable it is to us when we don't have it. URL_0
We wish to have the attention and approval of others, since this is obviously a survival and reproductive advantage in society. Your brain's natural response to being dismissed or ignored, then, is to motivate you to gain more social acceptance. That being said, remember that the other person's action or inaction is no...
It depends on the chemical composition of the food or seasonings and ingredients used. For example cured meat. Cured meat or processed meat contains sodium nitrite. The heat when cooking allow sodium nitrate to react with the amines in the meat to form N - nitrosocompounds which is carcinogenic. Fatty foods. Fried food...
A combination of nature and nurture. Genetics obviously plays a role at the beginning of life. Someone genetically inclined to have higher cognitive functioning can still be a naive moron if raised in such a way. Same with an average Joe who's seen the world and learned how to process information in an efficient way.
First of all, these are not weights, they are masses. Weight refers to the force of attraction that objects with mass exert on each other. Mass measures "how much stuff" there is, how much force is needed to accelerate something (inertia) remember F=ma, and also has to do with energy. What I mean by the last one is tha...
when you turn on a conventional lightbulb it heats up in a flash, which stresses the filament. once it's stabilized at its new temperature it's generally fine, but it does happen that they burn out while on, usually if left on for a long time or if there's a power fluctuation
Does it?! I'm almost finished with my masters degree now and nobody ever mentioned that. Feels like I wasted all my university life.
I remember watching a documentary on reddit and before they went to investors they would have fake accounts to make the sight seem more active thus it seems more interesting. Now if where talking about companies like Google they were advertised by their professor who eventually got the entire universe hooked onto the p...
A factor no one else has mentioned yet is women entered the workforce. We essentially doubled the amount of available workers without doubling the amount of available jobs. When you have a lot more of something, in this case labor, the price decreases. It became an employer's market, no different than when a lot of hou...
There are specific assays for quantification of protein, fats as carbs in food. The specifics such as reaction, duration etc vary and there are many different techniques for each category, but they all traditionally start by weighting the food, drying it (some hours at ~ 100°C), weighting again and then performing some...
It's almost always FAKE NEWS. The rest of the time it's a reporter without much expertise in the fiend that's unrealistically impressed by a good science fair project. If you look at genuine science fair awards, [like these Intel ones]( URL_0 ), you'll see the same kind of small, incremental breakthroughs that you see ...
Because you're creating a vacuum in the straw. The space inside of the straw has to be filled with something lighter than the liquid (air) in order for it to escape through the bottom. Your thumb is preventing the air from being sucked into the top of the straw as the liquid leaves, which in turn causes the created vac...
When you sleep, your muscles lose tone and fluid tends to pool along your back. Stretching helps to massage fluid gently back into the normal position. Also, your muscles protect themselves from over-extension by inhibiting the nerve impulses as they approach their limit.
When you get dizzy, let's say from spinning too fast, your eyes see something different than your balance tells you. In nature, the most likely reason this happens is because you've been poisoned, i.e. eaten something poisonous. So you puke it out just to be safe. Your brain thinks that the dizziness is caused by somet...
An SSD is very much different from an SD card. SSD's, SD cards and phone internal memory for that matter uses the same NAND flash chips. However a fundamental difference here is the controllers. Imagine a room in which you want to fill in stuff and it has an automatic door. In layman terms a controller is like an autom...
Might be a number of things. 1) You aren't used to waking up early, so your body isn't ready for it. If you don't usually wake up at 7am and then suddenly do, it'll be hard. 2) It's often colder in the morning, especially in the winter. Getting out of bed in the cold is hard. 3) It's much brighter at 11am than 7am and ...
Sometimes they are co-developed, and this allowed for more variation during between what are effectively the same vehicle underneath, such as the 1990's [Ford Probe]( URL_1 ) and [Mazda MX-6]( URL_0 ).

Swallowing is aided by peristalsis. Basically, swallowing is not a passive thing aided by gravity. When you swallow, the muscles in your throat actively push food down your gullet. That pushing is peristalsis. When you're upside down, it works a little bit harder because gravity is the other way, but your throat muscle...
Honey is rich in sugars, which means it is rich in energy. That means it is a food that is prized by a lot of animals. As such bees have evolved to make a large surplus of honey, many times what they need to survive so that when some other animal breaks into the hive and eats the honey the hive does not starve to death...
I would assume this would be an unconscious effort to regain a sense of balance, control, and composure. We use our arms in locomotion for balance, so when our balance or equilibrium is interrupted (ie you take a fall), your body (which is really just a complex machine) engages its upper quadrant balance control module...
Um fresh ground peanut butter from a health food store comes in the containers you desire and its way yummier.
Disclaimer: I'm going to assume you mean something like "what is calculus". If you literally want to know how it "works", I suggest being more specific in your question, and also try to understand that calculus is a large and complex subject, so there is really no ELI5 answer for how calculus works as a whole. With tha...
Your body generates a fever in order to fight an infection. Molecules in your body (generated by the immune system or pieces of the bacteria/virus) signal the hypothalamus to raise the temperature of the body.

Not all forms of mental illness are hereditary. For example some forms of schizophrenia are related to the COMT gene. However, there are 20+ other genes with different connections. It may turn out that schizophrenia is like "cancer", a bad generalization based on common symptoms for many different diseases. However, tr...
