I'm bored, how could I feel good the easiest? Oh! Eat something! The feel good feelings are the easiest to access. Like the path of least resistance. Vsauce made a video about our mind's desire for stimulation. In the video, people were put into a room with nothing to do for an amount of time (an hour I think?). With t... |
If you're not being sponsored you may not make much money, I believe h3h3 does have various forms of sponsorship and/or companies paying for things. Its unlikely they will discuss details publicly, as such you may not know what the deal is behind the scenes. Some Youtube channels make money just by video views and mone... |
Yes, water in the wrong place, basically. Sea level rise is partly from ice on land melting, and partly from the water expanding a little as it heats. But sea ice is floating so melting it doesn't directly raise sea level, although it can unleash glaciers it was previously holding back. Droughts and floods are mainly d... |
Op, I've seen you try to correct several people answering your question correctly. Don't ask a question you're not going to listen to the answer to. First off, casinos don't "prevent" money laundering, the government does. In all honesty casinos probably don't care where their money is coming from. Other than following... |
In order to be sold in most markets, microwaves, just like most electronic devices, need to pass certification testing. If you don't have the right regulatory testing pass - and the right mark on your device - from CSA (Canadian), UL (US), TUV (global), CE (Europe) or whatever, you can't sell your device. A retailer co... |
Cop here, it's called Pace Clocking. Essentially what I do is follow behind a car and match my speed with them so I they are not pulling away or going closer to me. Once that is done I, I go a couple of blocks to see if they stay consistent at that speed. If they are over the limit I pull them over. Our vehicles at my ... |
Thrift store is an established location that takes donations of used things and resells them. They often are run by non-profits that use the donated goods and funds to help disadvantaged individuals. A flea market (or swap meet) is typically a venue containing a number of independent vendors. They may be selling all so... |
Pegging your currency to shiny metal means you give up quite a bit of control over your money supply. You can't "poof" in money like with a fiat currency, for example. This can be dangerous. Take the Great Depression, for instance. Banks don't store all of their deposits--they store a fraction of it and loan the rest. ... |
The difference is that ISPs can go "Hey Home Depot, James Smith who lives at 1234 Secure St. has been looking at home improvement products. You should send him ads in the mail." It's very different from Google telling websites that user 12345678 has looked at home improvement and having them show you ads for Home Depot... |
Well if you have a really large military, thats a pretty big deterrent for anyone to go to war against you. You have a huge military, ready to go and kick some ass. If you have a large military and someone else doesn't if you choose to go to war, you can smash them. You're ready to go, you can get in tons and tons of s... |
Auditing firm. Essentially they are hired by companies to ensure that their books have been prepared properly. That way they are all legal in their financial reporting. They will also assess the financial health of the company and prepare financial statements for them. ELI5: They make sure little Johnny didn't debit wh... |
Almost all animals have some level of emotion, whether it be how we interpret it as emotion or simply forms of communication. It is a sort of communication - If someone doesn't look happy they tend to show it (especially anger). The emotions we have, although sometimes annoying, help us be closer together and understan... |
The body is preparing for a fight. Unload waste now while you can. You feel lighter and more comfortable and so one less distraction. |
Suppose Joe owes you $5,000. He's 90 days late on his payments. You've probably already called Joe a few times to remind him. Maybe you charged him a late fee. And, of course, you've reported his late payments to a credit agency, so that anyone else who is thinkng of loaning him money will see that he sometimes is 90 d... |
The idea of those promotions is to get you to put more money on your credit card - you're supposed to think "Ooh, I can save money on *x*, but I'd better buy it now!" If they announce those promotions in advance, it encourages you to put off purchases instead, which is the opposite effect of what they want. |
If I am remembering correctly, the understanding was that the order went something like this: Earth - > Moon - > Sun - > "Stars" (including planets with everything else that's just a bright dot). So to the extent they observed the planets moving behind the sun, it made sense since they were behind the sun. One thing to... |
Chances are, even if your girlfriend went in voluntarily, if she is placed on a hold, then she will be held involuntarily for 72 hours. If she readily admits to being a danger to herself or others, she will very likely be put on a hold and transferred to a facility for treatment. If she does not meet the criteria for a... |
The bacteria that grows and multiplies in your mouth while you sleep, when they are relatively undisturbed. If you woke up every so often and drank something, that would wash away much of the bacteria (into your belly) and you would have noticeably nicer-smelling breath in the morning. You always carry a fuckload of ba... |
Just like seeing is defined by a series of observations and sensations caused by light waves (electromagnetic radiation in a particular frequency band) hitting the retina and hearing is caused by sound waves (fast changes in local air pressure) vibrating little hairs (cilia) in the inner ear, taste is caused by chemica... |
Yes, it is very possible for something to do this. You can infact do this with your hand. Try just waving your hand up and down really fast and you'll see it as one big splodge. Think about those toys that have a picture of a cage on one side and a bird on the other. You start out with one side, a picture of a bird the... |
Charging interest isn't allowed in Islam. So banks offering loans suitable for Muslims must make money in other ways. For example there are Islamic mortgages. With a normal mortgage, you borrow money from the bank, use that money to buy a house, and pay it back with interest. With an Islamic mortgage, the bank buys the... |
It's important to understand that trials are very expensive and—if the accused is not granted bail—he/she will be kept in jail awaiting trial (which could be months away). This typically costs taxpayers a lot of money, wastes the court's (and everyone else's) time, and overall it's just a bad situation. When someone is... |
Because when you say or read a word, the thingamajigs in your brain fires signals. As you repeat your actions, the intensity of those signals reduces and hence the word starts appearing foreign. It's called [semantic satiation.]( URL_0 ) Think of it as a similar process to how you drain out background noise. If you hea... |
Smartphones are very small. They are built with components that have to fit very tightly together, otherwise there either won't be room inside the case, or the components might interfere with each other, or the heat dispersal won't be effective and the phone will overheat. The same problem applies to laptops too, which... |
There's a couple of different reasons but I'll try to separate them. Chemically, there's 3 different 'types' of tears; Basal, Reflex, and Emotional. The other two tears are a result of irritants or just general lubricant for the eye in the form of mucus, but emotional tears are made up of stress hormones such as cortis... |
Do you mean why are ships not removed from the bottom of the ocean when they sink? Typically, if the cost of recovering a sunken ship is less than the benefit of selling off its parts and cargo, it *will* be recovered. If not, it won't. It costs time, money, effort and a certain amount of risk. Nobody wants to do it un... |
**Old, wire-based phones** Sound is just ordered vibration. When you speak, your vocal cords shake the air, and that air shakes the ear drum of the person you talk to. That person's brain turns that shaking into meaning. A phone has a microphone, which is kind of line an ear drum. It contains a surface that turns those... |
Because the money he has is money he made, himself, through his business. It isn't money he inherited from a family member or something. "Self-made" isn't about where you came from, it's about how you got here. Because he did not inherit any significant wealth. He was born in a fairly rich family, but nothing compared ... |
I can't explain why you'd only stop liking it now, although I'd suggest (if it's a soapy taste) that it's an epigenetic factor. URL_0 Basically, you're genetically programmed to dislike it now. |
Dry Cleaning Shop Owner reporting in! Cabtab314 is correct, (we use a solvent called Perc in the UK), and yes because Perc is a solvent the garments get thoroughly "wet" but the solvent evaporates in the dry cleaning process. In regards to your other question, we have a huge issue with dry clean labels... Many companie... |
Couple of different answers to this. This is a bit long, but it should help. It mostly has to do with avoiding predators and not being eaten. Consider the Rabbit - their movements are either big and strong, fast hops and leaps. Or when are still, only their faces, where their sense organs are, tend to move around quick... |
Basically, we're gonna hit a wall with what we can achieve alone. Humans someday will reach a pinnacle of technology - tech becomes increasingly more and more complex as time goes on, so it is logical to infer that eventually we won't be able to make anything new alone. Look at anything modern, like smartphones. There ... |
Their brains are more like tiny machines with sensors. No rational thought, or new ideas. New patterns in behavior cannot be taught to their family, it has to be inherited through genes, where mostly only small changes occur. Over vast periods of time, the ones that were best at finding food, avoiding predators and mak... |
The pressure from your weight pushes the water from under your shoes increasing traction and grip |
Most mammals, including the majority of humans, naturally stop producing the enzymes that allow you to digest lactose shortly after leaving the infancy phase of life. For humans this happens around age 5. It is a mutation in the human population from Northern Europe, the Asian Steppe, and some parts of Subsaharan Afric... |
Pretty simple. Because they are easy to grade and organize students based on a score. There are much better ways to gauge learning, but they require a lot more time and effort than filling in bubbles and running them through a machine. So yes there are better (but more difficult and costly) ways to measure success in s... |
Unions aren't good or bad for society. They are a solution, and they are good if you have the problem they solve and bad if you don't have the problem. The problem that unions solve is an imbalance caused when the owner of a business can direct unilaterally and individual workers can't participate in that direction pro... |
Vein problems, hyperviscosity, overabundance of clotting factors, less c and s proteins, basically anything to do with Virchows triad. Some people have genetic disorders that predispose them to forming DVTs. Obesity is also a factor, as are medications, supplements, alcohol use, activity level. It's also possible to ha... |
The current scientific understanding (which in this area is quite incomplete) is not that sleep is a time for neurons to "rest". They continue to be active during sleep, just in different patterns. No one really knows why we need sleep, but there have been some cool papers in the last few years showing that the space i... |
Most consumers of funerary services are not active comparison shoppers. They are very busy processing a life event, and an industry has grown up to exploit that situation. In addition to it not being something people tend to comparison shop, it's also a heavily regulated industry in terms of who can sell what, offer wh... |
0^0 is not 1, it is undefined. You can construct limits that approach 0^0 that converge on 1 or 0. 0^0 is what's called an indeterminate form, meaning it doesn't really have a concrete value, or alternately, we choose a value for it to make our lives easier depending on what calculation we're doing at the time. For exa... |
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. So we get blue light from all sorts of angles, which overpowers the red light that manages to get through to us. When we look towards the sun at sunset, we see red and orange colours bec... |
Two theories: Most of it has to do with blood supply. Your fingertips get more blood than your toes (this is why frostbite affects toes more easily than fingers). More blood means that the portion that produces the nail gets more nutrients so that it can produce more nail. This is also why in the summer, the higher tem... |
from what google have said, the point of google fibre was to prompt competition... to make the existing providers "pick up their game", provide faster, cheaper, more relyable connections. what actually happened was that the oligopoly that controls americas isp's just banded together, and forced through laws essentially... |
I assume you're talking about sleep debt? Sleep debt is a little more complicated than "accumulated tiredness." It generally refers to a chain of changes and harms in the body as a result of poor sleep or insufficient sleep: increased risk of obesity, heart problems, stroke, cognitive decline, high blood pressure, high... |
Serotonin and dopamine aren't hormones, they're neurotransmitters. Neurotransmitters behave slightly differently than hormones. One critical difference is that neurotransmitters are produced locally by the neuron, whereas hormones can originate from an entirely different part of the body. There is something called the ... |
There are many groups in the US Government that are like minded and tend to "caucus" together. Said Differently its a group of congress the meet to pursue common legislative objectives. There are ones on all sorts of subjects from Farming, to military. The Freedom caucus is a conservative one who aligned with the Tea p... |
Yes and no. No electronic storage medium will have an appreciable change in mass when "full" or "empty." Magnetic storage media (HDDs and tapes) work by flipping magnetic domains on the media which does not change their mass at all. Other types of memory (RAM and SSDs) work by storing electrons in capacitors or floatin... |
The fluid going into the bottle is very hot. This means that the air bubble under the lid is also very hot. When the fluid and the air cool down, they both shrink. This causes a partial vacuum inside the container. Since the sides of the bottle can't compress, the little button on the lid pops in. One easy way is to bo... |
This was actually an open question just a few years ago. Until some doctors took MIR scans of someone cracking bones. It is actually Nitrogen gas that is dissolved in the soft tissue around your joints. When you "crack" them the Nitrogen is forced out of the tissue very rapidly which causes the sound. It takes time for... |
primary = born that way secondary = raised that way that's typically how those words are used with regard to most health /medical conditions btw inherited, or primary, psychopathy is really (really) rare, but it happens and so you see the 'symptoms' - like an utter lack of empathy, inability to know right from wrong, n... |
A two-dimensional denizen of [Flatland]( URL_0 ), which Sagan refers to, would have length and width, but no height. You couldn't pick him up, it would be like trying to pick up a shadow. One unusual notion, which Sagan also mentions, is that you could--looking down at him--see inside his body. Just as you could see in... |
Whether cheap resources would "destroy an economy" depends on your perspective. Probably a more accurate thing to say would be that it would be "economically disruptive". For instance: some have theorised that in the future we might be able to mine massive amounts of gold from asteroids. If SpaceX suddenly landed an as... |
Data recovery software only works on data that is still (technically) on the physical disk. Let me explain: Data on physical medium is stored as 1s and 0s, you may already know this. So there's different sectors filled with sequences of 1s and 0s. In order to actually use storage medium, in computing we use file-system... |
Yeah for the most part Radiation only travels so far before it becomes negligible. For the most part nuclear test sites are in the middle of no where. Russia tested in the middle of siberia which is thousands of miles from civilization. The U.S tested in the Nevada desert fairly far from any civilization. After a while... |
Forgive the tongue-in-cheek response, but they don't. If they forgot something, they no longer remember it, and if they remember it they have stopped forgetting. Semantics... I know. Ok more seriously now, memories are made by specific patterns of neurons firing in the brain. Each memory has its own unique pattern of n... |
When your body is ill, it raise your internal body temperature to make it less hospitable to the harmful organisms. Normal air temperature feels colder since the relative difference is greater, so people tend to load up on blankets to keep themselves from feeling cold. While sleeping, if your body tries to revert back ... |
When we walk, it's left-right-left-right: the march. So the "natural" rhythm for humans is going to be in twos or multiples of two. Two sets of left-right is 4/4 time, which is a better fit if you sing or play longer phrases than fit in a bar of 2/4. Think of your typical marching song e.g. "I don't know but I've been ... |
Speech and voice are pretty complicated, but the ELI5 version is this: you can make your voice produce a particular primary frequency or note, but there are many different shapes to your mouth, tongue, lips, throat, etc. that add harmonics (other frequencies) to produce the composite note. Check [this video]( URL_1 ) o... |
Birds are often brightly colored and noisy. They don't avoid predators by hiding - they avoid them by simply being able to *fly away* at a moment's notice. The noise is helpful actually, as birds warn each other if there are predators nearby. Those birds tryin' to get laid, man. They squawk so females come to them. Moc... |
Well supplements are not FDA regulated/registered so they don't necessarily need to back up their claims with anything (simply look up a homeopathic principle of "water memory"). Most proteins are harshly broken down by stomach acids (pH ~2) and then they are cleaved with intestinal enzymes in the duodenum (ex: chymotr... |
There are nerves in the body called *nociceptors* that process pain signals in the body. In people with CID disease, those nerves are missing. |
It releases pressure. Certain gases build up in joints and collect into bubbles. Popping these bubbles lets the joints settle into a more comfortable spot. |
The use active noise reduction. There are two microphones, one pointed towards the mouth and one pointed away. One picks up speech + noise and the other just picks up noise. Subtract the 2nd signal from the first and you are just left with the speech. Similar technology is used in telephones, noise cancelling headphone... |
u/Ender37 is wrong. The surface of a curling rink is not smooth, but is pebbled. This effect is achieved by spraying drops of water onto the ice that freeze into little bumps. The pebbled surface actually decreases friction for the stone because there is a smaller area of contact between the stone and the ice. The swee... |
Many computer systems put in a deliberate pause to make it harder for people to guess passwords. If you can only make 10 guesses a minute, instead of 100, it makes it harder to get into the system. I'm going to assume you are talking about something like school workstations or business/office laptops. While true that t... |
You'd be surprised at the resolution most billboards are printed at. When you are standing 20 feet away or more the DPI requirements go *way* down. Those big 48 foot wide billboards? Often less then 10 pixels per inch which means a 10MP image is all you need (though due to the way many are printed you don't have the sa... |
There may be many reasons, I can speak to a few only: Pain can become a measure of accomplishment or value, similar in logic to how something that costs a lot is valued more than something that has a very cheap price tag. It can also be associated with greater value to come, so the endurance of it can be seen as heroic... |
guesstimation basically. Heart rate correlates somewhat with level of physical activity which in turn correlates with calories burned. If you throw in some other tools like accelerometers, they can get a better idea of what you're doing (running looks different from biking looks different from swimming, looks different... |
The sword is a side arm which meant that it could be carried in normal daily life, and it would often mark the wearer as landed gentry who might kill you for dishonoring him. Dueling with swords was popular long after the sword itself became obsolete. It was a status symbol for thousands of years and when things are sy... |
This is actually a pretty big question in some Christian communities. There is a question as to whether or not the Old Covenant is still "legally" binding to Christians. There are generally three trains of thought; 1) Christ's New Covenant was sealed and put into effect at the Sermon on the Mount, nullifying the Old Co... |
Our brain isn't "doing" anything in that sense besides sending and receiving neural signals. Let's take the bending of your arm for example. An overly simplified explanation of how that works is the brain fires a signal down the nerve that is connected to the muscle. At the nerve-muscle connection, various processes oc... |
I'm going to be assuming a basic knowledge of AC power for this: So in single phase AC your active wire is cycling from +240V to -240V and back at 50Hz (Depends where you live). This means that the circuit will be at 0V (turned off) for an instant 100 times per second. In 3 phase AC, 2 more active wires are introduced.... |
They would rather a site newbie not have to search to find the "sign up" page but rather a returning, and more experienced site user navigate to find the login page. Maybe easier for new users. Helps guide them to what the website wants most, new users. I am not sure about this but I have seen similar things on in hous... |
A lot of parasites never live anywhere besides a host or their byproducts. Many worms are passed through feces into a body where they live until their progeny is passed in feces and the cycle continues. Ticks and other blood suckers need a host to get food, but just as you don't need to live at a restaurant, they can s... |
Not a doctor/biologist, but from what I understand, fevers are caused by your body essentially heating itself up, hoping to kill any intruders. However, the body cannot selectively heat itself up (as in heat only the heart, or the arms, etc.), and your brain heats up too. In the brain, there are a lot of complex proces... |
Well, Norway seems to have particularly notable oil (and mineral gas) resources. And do you know what they do? The oil company is partly-state-owned (Statoil) and they save the vast sums of money for the norwegians of the future. They enjoy a very high standard of living now, so they don't need more (like a permanent s... |
Its called a hypnic jerk, its pretty common especially when very tired. Start dozing off and you make a hard left turn back into being awake as your exhausted mind compensates for an issue that doesn't seem to be there at all. Some people think its an evolutionary throwback to the time of apes sleeping trees getting jo... |
Because they have investors that keep dumping money into them. Basically, there are people/companies that believe strongly that eventually, they'll start earning money, and when that happens, they'll be able to get a return on their investments. Until then, suddenly stopping to invest could possibly make all your earli... |
I think the biggest lesson in thinking differently comes from debugging. It really humbles you. A common scenario is going over the same piece of code that is creating a bug, but being absolutely certain that everything you wrote is correct. *There is no bug in my code. The computer is messed up somehow* is a thought I... |
The same reason why you'd hate a big, noisy, dangerous looking and unpredictable machine. Would you feel comfortable next to a huge robotic arm that could unpredictably turn around and punch you in the face? That's got to be more or less what a vacuum cleaner looks like to a cat. It's huge, and makes an awful noise at ... |
First, I'd say don't think about practical applications now, think about what the world might be like in 20 or 50 years, and what the practical applications will be like *then*. With the [inevitable march of technological progress]( URL_1 ) eventually almost everything a human can do that's 'productive' is going to be ... |
Nordic countries use this system without a problem. It makes for neat headlines if millionaires get caught speeding, since their tickets might become hundreds of thousands of dollars, but other than that, I am not aware of any particular controversy surrounding their use. Fines for what exactly? No one likes the idea o... |
Those are some big questions! It's very hard to explain simply but I'll give it a shot. Dark energy: Gravity should be pulling everything together, but instead we see things moving apart. At first we thought it was just momentum from the big bang, but now we see the rate that things are moving apart is actually increas... |
[Drug tolerance]( URL_0 ) can be the result of a couple of different bodily processes. Pharmacodynamic tolerance is usually the one that relates to psychoactive drugs like heroin, so I'll explain that. Essentially, the brain has a bunch of receptors that the drug attaches to to make you feel high and slow your body dow... |
We don't get hurricanes per se here in Iceland, but storms in excess of 40-50m/s are common in winter (that's similar to a cat 2/3 hurricane). The local wildlife - and we also leave our horses outside all year, no matter what the weather is like - doesn't seem to be bothered much. They are very good at finding relative... |
The brain itself doesn't have any pain receptors, but it's surrounded by lots of different tissues (muscles, nerves, blood vessels, membranes, etc) that do have them. So you can still feel pain in your head, it's just not being sent directly from your brain tissue. Headaches are not problems with your brain. Instead, a... |
A lot of how your specific taste buds work actually is controlled by your genes. For example, whether or not you like cilantro is genetic. Another example is broccoli and other similar vegetables. They have a compound in them which some people taste as bitter, while others don't, because some people have a gene which c... |
As stars die they start producing heavier and heavier elements. Then when they go supernova these elements are flung into space as dust and gas (star dust). This then coalesces to form planets, just as Earth did. You are made from matter from the earth, hence you are made of stardust. A big thank you to everyone who re... |
Our faces evolved as signaling devices, and our brain evolved with it. We are super duper dialed in to looking at people's faces, and a large part of our brain is devoted to precisely that. We can distinguish between identical twins based on the tiniest differences in their faces, due to our specialization in that narr... |
Because light entering the edges is entering at a sharp angle, is bent to travel through the length of the material, bouncing off the sides until it exits the other end. Similarly, the light you see coming out of the edges has already travelled through the length of the material. This means that the material absorbs an... |
Usually due to association. Pavlov did experiments where he would feed a dog and ring a bell. At first there was no correlation. However over time, Even when no food was served. A ringing bell would make the dog salivate in anticipation. When you pee you hear the splashing and see the liquid. You associate these things... |
You have the largest concentration of sebaceous (oil producing) glands in your face, back and chest. The sebaceous glands enlarge at puberty due to an influx of a testosterone hormone called DHEA. That over-stimulates the production of oil in these glands. Acne is an inflamed pore filled with oil, bacteria, and dead sk... |
It depends on how you obtain the income. If you're being paid as an employee, then your employer is reporting how much they paid you and that can be used to confirm the amount you report. If you're a contractor then there is more room to do illegal stuff, but you can easily be caught out. The IRS regularly audits peopl... |
Overall symmetry makes movement and maintaining balance easier since it keeps your center of mass centered inside your body, so there's some selection pressure on evolution to keep such a shape. Sometimes asymmetry still sneaks into living beings where it either provides enough advantage to outweigh the disadvantage (l... |
The simple answer is that by the time someone can be called a dictator, they've taken over the media, silence dissidents, censored the internet, murdered/jailed the opposition party and control information to the point that an alternative to the narrative doesn't really exist. Especially when so many people are just bu... |
Lot's of salt, sugar, and fat for preserving and improving flavor lost due to the need to preserve. These are hallmarks of ensuring that food is coveniently available even in hard to reach places or during times where the otherwise available ingredients would not be available. Basically, you should opt to eat fresh ins... |
By this logic if someone on a team cheats we should disband the team. The organizations aren't fundamentally corrupt, certain people are. A number of countries are themselves corrupt or benefit from the IOC/FIFA corruption so they have no incentive to shut it down. Other countries are refusing to play their game. Just ... |
Physics rather than chem, and it's subatomic/wave rather than atomic. Light is a wave (or a particle, or both, but we'll stick to wave) of electromagnetic radiation which travels through a variety of media (air, vacuum, water etc.). Visible light is made up of several different wavelengths which we see as colours. The ... |
Because they are related. And they haven't evolved much from common ancestors. They all pretty much have the same niche as apex predators. Like fish all have a similar design, because they all live in water and have to swim to get places. It worked for their common ancestor and it continues to work. Like dolphins and c... |
