Sure it's a motion sensor, and not a light sensor? I know many nightlights have light sensors so they switch on in the absence of other light. |
When employees depend on their employer to provide healthcare then they are much more likely to stay in a terrible job with abusive management. It's the same with foreign employees with a corporate sponsored work visa. Those employees will get kicked out of the country of they lose their job for whatever reason. That's... |
Technically speaking, fighting isn't allowed in pro hockey, there are rules against it and players who engage in a fight are assigned penalties. There's kind of an unspoken code among hockey players though that dictates when it's appropriate to pick a fight with someone. Generally fighters (or enforcers or goons as the... |
Phobia development is (as with all psychopathology) immensely complex, and can occur in a variety of ways. Most theories stem from a behavioral perspective, which focuses on how an individual has learned to associate a phobic stimulus (e.g. being in a basement) as predictive of a negative experience (e.g. being assault... |
The belly button is a healed scar from the umbilical cord that supplies the fetus in utero. A few weeks after birth, the stump falls off and the scar heals up. While the process is similar in each person, there is no uniform rule to how the scar has to heal, so they all look a little different. In addition, the belly b... |
Having to fight a lawsuit. Why spend money when you can just come up with diff name. Tesla just went through this trying to name the the model 3 the model E, another car company already had the name and ruined his plan to have his first 3 cars the model S, model X, and model E. I'm sure you can guess why, even though t... |
My view on this has always been that women's jeans are designed without pockets to help sell other products. If they have no storage built into their clothing they will have to buy an accessory such as a handbag or backpack which allows a company to have a larger variety of products. People do. For example, there's a s... |
Subreddit Simulator uses markov chains to generate text. You can think of markov chains as an algorithm that stochastically (so randomly) pick words from some source. The likelyhood of it picking a word depends on how often that word is used in that context. So they feed text from some subreddit into the markov chain t... |
The voice can be used in different ways. One of the most important aspects of that is how your vocal cords vibrate. The vocal cords, basically two folds of mucous membrane (hence the official name "vocal folds") in your larynx. There are muscles to push them together, and combined with air pressure coming from below, t... |
Countries have had Census programs since the Egyptian empire. Taking the averages of those, and applying it to other areas with assumed similar population density, allows for a fairly accurate prediction. |
It is not possible to make something that cannot be hacked. Just like everything else, if humans can build it then humans can unbuild it. It's very, very difficult to be sure that a program is completely secure, unless it's a very simple one. If we take a very simple model of programming, it's basically that you have a... |
Pedophilia is no more prevalent in the Catholic Church than in wider society. However, the Catholic Church combined two dangerous attributes: 1. Offered programs with minimal supervision that afforded direct involvement with children. 2. Had an institutional bent towards secrecy and hiding mistakes. Bear in mind that t... |
Imagine a kid on a swing. You go up behind them and give them a gentle push, in response to which they swing back and forth gently. Then you try giving them a bigger and bigger push and they swing higher, but eventually you realize that pushing them too hard will just shove them off the swing. Instead, you look at givi... |
Legs would be blown into the windshield. [Here] ( URL_0 ) is a youtube video showing exactly what would happen. Their knees would most probably go through their face. there is quite a force, an explosion actually, it has been known to kill babies and youngsters. |
Reading and moving your hands requires two separate parts of your brain. When you do both for the same task, you are creating stronger pathways in your brain making it easier to recall the information later. I learned this from a presentation on how to give good power point presentations by Melissa Marshall from Penn S... |
It's because physical inactivity causes the lymph circulation to slow down. Lymph is a fluid that circulates through the lymphatic system, carrying proteins, fats, bacteria and other stuff around our bodies. It refreshes the tissues, thus improving their functionality. Unlike the cardiovascular system, the lymphatic sy... |
Not completely sure, just throwing an idea out there. Your big toe has the largest surface area compared to the rest of your toes, so the nail polish will last longer. The smaller toes have less nail polish, so the nail polish will last shorter. |
They are currently in the middle of safety testing in several States. They will likely be street legal within 5, but will require driver's licenses still. It will probably be 10-20 years for it to allow people without licenses to ride in one solo. |
Another factor is the "hollowing out of the middle class": almost none of the economic growth of the past 40 years has gone to the large middle portion of the US population. Most of the benefits have gone to the top 10% and especially the top 1/100 of 1%, and these are not the people who do most of the shopping at JCPe... |
Most of the time, they have a special camera with two lenses that it records simultaneously (one for the left eye, one for the right). Some films that wanted to add 3D as a gimmick were shot in 2D and then modified in post-production to add 3Ds (where artists modified the original shot to create a left and right eye ve... |
I don't necessarily have an answer for you, but it did remind me of an experience I had. My wife *loves* garlic. It's nearly a fetish. She has similar feelings about ice cream. One of us made a joke about garlic flavored ice cream and the quest was on.. she found a garlic ice cream recipe online and crafted it with car... |
> selling for ...more than they are worth Can you clarify this? How do you know they are not worth what other people are willing to pay? At any given time there are going to be bubbles in some localized markets, it's just the nature of markets that aren't perfectly liquid. That said, the bubble that popped in 2007 was ... |
Technically yes, but it's uselessly blurry, because their eyes are pointing in different directions... |
Focusing on something that is close to you automatically causes your eyes to cross, so it's a normal action that your body does a lot, both automatically and on purpose. However, even when focusing on a point that is infinitely far away, your eyes would never need to look further apart than parallel to each other, so g... |
Dust is a lot of dead skin cells, actually. That and hair and fluff from clothing + outdoor particulates. But yep, you're cleaning up your own skin. Fibers, pollen, mites, hair, and dander. Dander are bits of dead skin cells, fingernails, etc. Our skin protects itself with layers of dead skin cells. When you get scratc... |
It's pretty much impossible to explain what it feels like, but the basic idea is that you have receptors that respond to the presence of various chemicals, more strongly to some of them than to others. Things have a smell because of trace amounts of chemicals circulating in the air, and getting picked up by these recep... |
Alright, I might be wrong, but I actually read an article about this, so bear with me. From what I've read, hiccups are an extremely old reaction we have from before we were land based organisms. Basically, every so often, usually after drinking a lot of something or swallowing to much air, our brain decides that we ar... |
All of the components of the blood are replaced at different speeds. It takes about 4-6 weeks to completely replace the red blood cells, which are the oxygen-carrying components of the blood. Drawing a bit of blood does not really have a major effect on the body because it's a small proportion compared to the overall a... |
While drying you slough off dead and dying skin cells loosened by the wash. these combined with the steamy warmth of your bathroom allows bacteria to grow. They die and their corpses rot. And that stinks. The thing most people tend to forget is that there is always a bunch of nasty bacteria in the air all the time, loo... |
The station gives you a "make-good" and airs spots correctly to replace those that get cut off. Depends on the exact agreement between the company and the tv station, if the tv station broke the contract then the company can sue the tv station and ask for its money back, if they can't find any other agreement. Generall... |
When lightning strikes it heats the air so fast it creates a big sound wave. That wave moves out from the Strike at the speed of sound 700ish mph. As it moves out it bounces off stuff like buildings, hills, trees etc. those bounces go in every which direction and can bounce back and forth. If you are a long way away, y... |
"It's down" usually pertains to the fact it's being cleaned. It takes time to clean them, your dealing with milk and if that goes bad in the machine... Fryers are grease and everything you throw on them either burns up or sterilizes, plus they take like 5 minutes to clean vs. 3 hours for the ice cream machine to run a ... |

If you have $3,000 in savings, it's not going to do much when you need life-saving heart surgery that costs $700,000, or when your toaster burns down an apartment building causing $350,000 in damages. "Paying yourself" the monthly premiums isn't going to do anything either. If you do have a lot of money on hand, you do... |
Until the modern age(locomotive trains, and telegraphs), knowing precisely what time it was, was not very important. Only when communication and travel between groups of people in different places became the norm, did accurate timekeeping matter. There are on simple clock namely the [Water clock]( URL_0 ) that have bee... |
I'm not an expert in acoustics or physics by any means, but I would think most of the energy dissipates exponentially in the soundwaves, as they are going out in a complete sphere from where the sound originates, so the energy hitting your eardrum is just a tiny fraction of what was put into the guitar string. But then... |
Basically because the four gas giant planets captured all the smaller, rocky objects as moons. Jupiter and Saturn, for example, have a couple moons that are about the same size as the planet Mercury, and made of similar stuff. The four gas giants all have dozens of moons. Those moons could have become planets on their ... |
To start with, there is nothing more dangerous about a solar eclipse than just looking at the sun normally. Animals know not to look at the sun, therefore a solar eclipse is not concern for them. They just want look at it. Humans are told not to look directly at a solar eclipse because looking at the sun is dangerous, ... |
Because you're 'overriding' the automatic system in your brains that regulates your breathing pattern. Breathing has 2 components: autonomic control and plain physics. The autonomic control center regulates your breathing frequency/intensity depending on CO2 levels in your blood by stimulating your breathing muscles in... |
That's called the [Maillard reaction] ( URL_0 ). There are many reasons that meat can turn brown. Cooking meat at a high temperature browns meat because of the maillard reaction. As meat ages it turns brown from oxidation. The oxidation process is a result of the bound iron molecule in myoglobin going from the ferrous ... |
It is a brand name that IBM is applying to a large number of artificial intelligence, machine learning, and pattern recognition technologies -- including the software, hardware, and services involved in doing so. Originally, it was announced as the machine that could be humans an Jeopardy, but it's really a big collect... |
One side of the clip has a light and the other has a sensor. When you clip it on your finger, it shines both red visible light and infrared light through you finger and it hits the detector. oxygenated blood and deoxygenated blood absorb different amounts of infrared and visible light, so by comparing the amounts that ... |
Well first, not all obese people have underdeveloped legs. If an overweight person is active and heavy, chances are they kick like a horse. Their core might be better developed than you'd think as well, since a lot of abdominal muscles act to keep the torso in line and that becomes more difficult when reacting to shift... |
They sell things for more than they cost. And sometimes they sell at a loss to get you in the stores and buy things with a larger profit margin. Because the stuff they sell is cheap junk that costs them next to nothing. Their stores aren't fancy, and they don't spend a lot of money on advertising. Then they pay their e... |
Forgive me, for I'm not an expert, nor do I have any qualifications that would be considered remotely Psychological, but I would think it has something to do with Love. Or more specifically, it's a coping mechanism. We all want to be verified in life. We all want to experience something with someone else, to make sure ... |
When there is a Queen on the ruling throne, there is no King. Her spouse will have another, lower title (like Victoria's husband Prince Albert ("His Royal Highess the Prince Consort"), or Elizabeth II's husband Prince Philip, the Duke of Edinburgh). She may marry anyone she chooses, but in reality will tend to choose s... |
Lasers are pointing all of their energy in a single direction, so that energy stays concentrated further. So by the time it gets to a target, there is still enough concentration to do damage. Flashlights spread their beam in a wider cone, so as that come gets bigger and bigger each square inch of beam becomes weaker an... |
Workplace psychology is complex, but it's generally accepted that social interaction in the workplace is vital, especially *in person* interaction. There are neurological processes at work when engaging in things like eye contact that simply don't happen when trying to communicate over IM or email. There are of course ... |
Hmm this is facinating already. I see my memories in colors. Same when I mentally picture or visualize imagined/self-created landscape, imagery or scenarios in my head. I'm also able to do this outside my "eye range". I can distance my own being from the equation completely and project myself into an imagined world out... |
Last year's winners (for the big categories) are invited to present their award this year. The Academy invites other A-list people to present or sit in the audience for ratings and prestige, especially if they had a movie this year. Studios get a certain number of seats that they can give to anyone, obviously executive... |
They do, but a big part of the Academy Awards are the commercials. Some of those are nationwide and they would play on the online broadcast, but a large chunk are also local, based on where you live, and also based on the cable/tv provider you have, and if you watch online those commercials either go to the wrong demog... |
Many U.S. States were sparsely populated when they became States, so it was not clear which would be the leading city. Often something near the geographic center was chosen. Since cities close to shipping ports tended to become the largest and most important cities -- and large bodies of water are rarely in the center ... |
If there magnets are perfectly aligned, you can represent this as three equal and compressed springs lined up next to each other. Each will expand and the two outer springs will be pushed farther away from the center spring until they no longer exert a force on one another that is greater than the force of friction. Si... |
Most simply, yes. Your "furious masturbation" would essentially be the same as a 20(?) minute unilateral arm workout at the gym. Try switching hands every time to balance things out. Possibly while squatting as well to work more body parts. |
Everyone has hurt themselves, most people have broken a bone, many have had some kind of semi-serious soft tissue injury. I don't think anyone can truly understand what it is like to have a mental illness - most of which cause thoughts and feelings in a way, and to an extent, that normal functioning people don't get. E... |
It actually is helpful! It A) makes sure you are reading the question and B) makes sure that they get the answer to the question they asked. For example, "I am not satisfied with my job", "I am satisfied with my job" and "I am happy with my job" all sound really similar but there is error that comes from the subtle way... |
The point of language is communication. It doesn't do any good to you to display your vocabulary in front of an audience that can't understand half of it. You might sound pretentious. Especially if the audience doesn't care about learning new words. |
They have a "belly" (abdominal) and a back (dorsal). They are not symmetrical inside. The neural system is the top side, the digestive system is the bottom side. And they aware of which side is up and down. Not all "worms" have the same body plan. Segmented worms, earthworms for example, are bilaterally symmetrical, an... |
Triglyceride is the fat (strictly speaking it's three fatty acid molecules linked together by a glycerol molecule) which is carried in your blood in a 'bag' made of either HDL or LDL cholesterol. The bag is made of HDL if it's moving from your body to your liver, i.e. taking fat to be 'burned' and LDL if it's the bag t... |
No, they use GPS. However celestial navigation is still taught to be used as a fallback, in case the more modern systems fail for any reason. As Schnutzel said, ships don't use constellations anymore. GPS systems, which is when satellites figure out exactly where you are using the speed of light and clocks(!), are much... |
Just spitballing, but human brains filter a huge amount of information all the time, to include ambient noise. We usually don't think about it because it isn't relevant to any of the decisions our brains think we're going to need to make soon. The sudden absence of noise, however, is unusual. It breaks the pattern, and... |
Naturally formed gems are not perfect. They have atoms of other elements dispersed within their crystal structure. When a gem is grown in the lab, it is usually 100% pure. There are no imperfections, (or nearly none). So when a gemologist observes the crystal structure, and they see no impurities, it is almost certainl... |
Once the rice cooker's thermal sensor detects the pot going above 212 degrees, the water has all been absorbed. At that point, the rice is done. To prevent the rice from cooking any further, the sensor automatically trips the shut-off switch for the heating mechanism. It isn't timer based. The temperature can't rise ab... |
A bail out is when external money is used (usually by the government, vis-a-vis taxpayers) to add cash to the bank to maintain its operations and not go bankrupt. A bail *in* is when those funds are sourced *internally.* For example, in Cyprus (where bail ins occurred), people who had deposits over the insurance thresh... |
That's a product of education, upbringing, customs, flavors and food you are familiar with... Also perseverance. Have you hear that "tonic water is an acquired taste"? You have to keep drinking it until you taste other things that the initial bitterness and end up liking it. And there are certain tastes that can only b... |
It's not magnetism, but electrostatics. Same effect as rubbing a balloon on your hair and then having it stick to a wall. When you rub things together electrons can come off thing one and end up on thing two. Both things now have an equal and opposite charge. If you rapidly separate them (styrofoam flying off), they re... |
It's not that we can't comprehend organisms that don't require water to survive. It's more that we have limited resources when it comes to searching the sky for planets. Scientists choose to focus on planets with a climate they *know* can support life, rather than focusing on planets have an atmosphere that *might* sup... |
It boils down to: Private companies are allowed to serve the customers however they want, even if the service is horrible, and furthermore, internet isn't a necessity for life. The government shouldn't dictate how the company supplies the product to their customers, as the company would best know how to make their prod... |
When you're afraid, or sexually aroused, or angry, or excited, your body goes into an aroused state (aroused in the general sense being increased respiration, heart rate, and blood pressure.) They're pretty closely related physically, so it's easy to misunderstand what caused the arousal. [There's a theory that when we... |
My guess is that it's due to relativity. The same thing happens with heat, if you eat(or feel) something really hot, a room temperature thing will feel colder. No idea why this happens, though |
Yes/No. When it comes to national spending, it's much more relevant that the next door country has 5 times as many soldiers, tanks and planes that you do, than it is that they spend 7,2% instead of 6,5% of their GDP on health, meanwhile them having "five times as many hospitals" has no effect on their foreign policy at... |
I saw some study a while back in which apes were given tokens to trade for food or watch "porn" of their species. Most chose the porn. Edit: It was macaques not apes. Juice was the currency that they were using. [Here's an article.]( URL_0 ) They also "paid" to see photos of high status males. there is a pretty good sc... |
Because the fart energy goes to the sound in loud farts. In quiet farts the energy is used for smellz. This is science. |
That is kind of quirky way to ask the question. I would phrase it as "Why is the government more willing to help get me a 100K for a student loan than 100K loan to start a business?" That is because the government does not provide loans to individuals, just guarantees to lender on behalf of private borrowers. 1. **Slow... |
Read and write speeds. A standard 128gb SD card will write at around 10mb/sec. An unimpressive 128gb SSD will write at at least 150-175+mb/sec. While the amount of storage might be the same, the speed at which it needs to be written and retrieved differs greatly. |
1) It is not a confession legally. They can say whatever they want and it is not a crime. 2) It is considered a part of their performances. Particularly if done on stage, so it is protected by the first amendment and by default assumed to be false. 3) In modernity they tend to live in States where it is legal. 4) They ... |
There are generally two type of fat - subcutaneous and visceral. Subcutaneous is best defined as the fat that you can see, the "inch you can pinch." You see it all over a person's body. In some areas it may be thicker than in others, but for the most part it's everywhere. Visceral fat (which gets its name from viscera,... |
Being Black/White/Asian isn't a species. Your professor is trying get that across. Your skin color or hair type is no different then your family lineage having big ears or a beak like nose. The CFTR gene, Sickle Cell, Tay-Sachs are common in groups of people yes. But that's just a simple case of those people in that ar... |
I was taught this in high-school ASL class. Basically, they're made up, kinda like a nickname. It's not an "official" sign, just something that the person, and others, recognize as representing their name. They're only used when everyone involved knows the sign though, otherwise they just spell out the name. There are ... |
While it may not be pleasant, it isn't inherently toxic (assuming it has been cleaned properly). Not only can you eat the skin of most fruit, the peel off a banana is relatively healthy. It provides more fiber and vitamins. The general consensus is however that the peel is pretty gross. (It is pretty nasty) |
Fire is a chemical reaction that is, by definition, when oxygen oxidizes another material, producing a lot of heat. So fire requires not only the fuel, but also oxygen. Oxygen can't be its own fuel. Fire is the rapid introduction of oxygen into the chemical structure of something else. Think of fire as like rusting , b... |
The first time someone thought to try and answer this was sometime in the 50s and the paper was called 'the cocktail party problem' they basically posed the question 'how is it, when I'm in a room full of 100 people at a cocktail party, that I can easily ignore many other voices and focus in on my target conversation?'... |
They died before it mattered. Their diets had far less sugar in it, so their teeth didn't wear as fast, and they had fewer cavities to deal with. By the time they started losing teeth, they were probably already old and close to dying anyway. As modern medicine started increasing the expected lifespan, dentures were cr... |
It's called the Garcia effect. One bad experience can ruin you on a food for life. It's got the name 'Garcia' after a rancher in the US who was having a hard time keeping wolves away from his ranch. He shot them but they (or rather, new wolves) kept coming back. One day he decided to leave lightly-poisoned meat around ... |
They will frequently be taking steroids/testosterone in order to build the relevant muscle-mass. Testosterone is the primary hormone responsible for male dimorphism (physical differences) which includes both muscle-mass and other features. It is next to impossible for females to build the extreme bulk of bodybuilers wi... |
Not a science-barista of whatever, but the ELI5 I got from my opthomologist family friend when I asked this years ago was that our brains really want to interpret signals from our eyes as things, and especially movement. So if you stare at a flawless white wall without moving your eyes for about 30 seconds, you'll prob... |
After about 12 hours tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste Part of it has to do with some of the gasses inside the water evaporating out, like how when you leave water out for a while it starts developing little bub... |
The brownie or what not doesn't have to be hot for it work. You are correct that the THC is activated by heat; which happens during the baking/cooking process... Once this process happens it doesn't revert back when cool. Pot is actually very low in THC and high in THCA - when smoking, the flame converts much of that T... |
Let me give an example. Let's say you walk into a rose garden. You smell the roses, you notice the vibrant colors and recoil your hand when it brushes over a thorn. Your brain just processed an extremely high quality image, flipped it, fed it into your conscious mind, associated it with sensory data coming from the nos... |
This is something that is still debated. First, some people insist they only need 5 or 6 hours of sleep a night and then survive off sugar and coffee to stay awake. Very few people can actually do this healthily, but some can. Scientists have linked a gene to most of the people who survive on extremely little sleep, bu... |
Yup which is why nuclear weapons are detonated every week right? /s Chemical weapons generally kill in horrible ways, indiscriminately and with little regard to battle lines or combatants vs. non-combatants. They also tend to kill the environment and in general just ruin things. Simply put... they are so nasty that eve... |
As it happens I just read about this the other day. [This is an interesting read]( URL_0 ) about this subject. I think most of those stories are anecdotes that have not been proven. Physiologically, adrenaline is released into the blood stream and probably wouldn't reach the muscles quickly enough to make a difference ... |
They often don't! Hundreds of thousands, if not millions, of trees are planted every year by squirrels forgetting where they buried an acorn or other tree seed. |
The sour face is biological because the puckering and sucking squeezes the salivary glands in your mouth to produce more saliva to dilute the sourness (also protecting your teeth). Disgust is also biological and the expression is universal among human cultures. Even blind individuals can make the disgusted expression. ... |
Domain names conventionally follow a reverse hierarchical system. The last portion (top-level domain, or TLD) is a signifier of purpose or nationality of the site (.uk, .fr., .jp; or .com, .org, .biz, .gov). The next to last portion is the owner of the site, or the name they've chosen for the site. The next portion is ... |
It has a wide array essential proteins that are complete enough to get a bee out of and its also naturally anti microbial so it serves to nourish, protect and defend |
Ultimately, we don't know for certain that the current set of "fundamental" particles really are fundamental. Currently the issue is that the particles we have are already so small that our current generation of colliders and detectors simply can't operate in the energy ranges we need to experimentally show that there ... |
Remember that water is heavier than the oil so it's trying to sink under the grease. The hot oil is generally well above the boiling temperature of water (water boils at 100 C, many vegetable oils will only burn at 300+C and don't self ignite until around 400C). If you've ever splashed a small amount of water in a hot ... |
They oxidize iron when exposed to air to produce the heat; basically they speed up the rusting of iron which is an exothermic reaction. Powdered iron and salt seem to be the main components along with water to allow the reaction to take place, charcoal to distribute the heat, cellulose as a spacer, etc. |
For every drug that is supposed to do "Y" to someone, it does "X" for a small percentage of people. This is what is known as a paradoxical reaction. It is very well accepted in pharmacological study. As to *exactly what causes it*, that is a very large and broad question to tackle. But a good way to understand it is to... |
