Touch work the same. You feet the c... |
Why do bacteria in our mouths find sugar more appealing to break down than other substances? | Sugar is the basic food for most life forms. Bacteria eat it, multicellular animals eat it and plants make it to use for energy. Salt on the other hand often kills bacteria, that's why salt is used to clean wounds, but salty foods are often sugary, so it creates a weird environment of killing some and making some stron... |
How did bullying even become natural to human interaction? | Why would it not be natural? Pecking order exists in almost all social mammalian groups. It's a competition and the weak get squashed. They don't get to breed and their genes die out making the next generation stronger. |

Why do they only play the newest movies at cinemas? | There are only a handful of screens in any theater, thus the theater must choose to play what will bring in the most people. The majority of people only see a movie once in the theater with most of them around the film's opening. A few good movies will have people return for subsequent visits or draw in people who were... |
Why do schools use and support the zero tolerance policy? | It's difficult to say what you are referring to, but I assume a drugs policy? There's a couple of important points. Firstly, the job of the school is not to get into long drawn out discussions about whether a particular action is OK on this occaision but not on another. You can't give one person a second chance but not... |
Why do some things need 4 AAA batteries instead of fewer number of a stronger battery? Example: Why use 4 AAA when one might be able to use 2AA. | AA are not "stronger" than AAA, they just have more power reserve. They both put out the same voltage though AA can probably do so at a higher amperage if required. By arranging the batteries in different combinations of parallel and series you can get different combinations of "power" or battery life .Voltage is deter... |
This Magician's Trick NSFW | Because your post isn't asking a simplified conceptual explanation, but rather for an answer, it has been removed. You should try /r/answers, /r/askreddit or even one of the more specialized answers subreddits like /r/askhistorians, /r/askscience or others too numerous and varied to mention. Rest assured this doesn't m... |
Why don't we have (many) cars driven only by electric engines with fuel generators instead of big batteries/standard hybrid systems? | What you're describing is an "extended-range electric vehicle" , that is a car that gets all its motor force from electric motors but also has some generation capacity onboard to increase its range. EREVs exist, two examples being the Chevy Volt and BMW i3. The reason they don't do 4wd or use multiple motors is because... |
If an ant die inside the anthill, what the others ants do? Or what happens with its body? | This will depend on the species of ant. Some will eat their dead, some will remove their dead .I happen to have an ant farm in my kitchen right now! They seem to mostly bury the dead ones. Possibly some cannibalism, but I'm not sure. Definitely burial in ends of tunnels and under the hills on the surface. If you've nev... |
How does water travel up a piece of paper/tissue? | Capillary action. "It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension. Capillary action occurs because water is sticky, thanks to the forces of cohesion and adhesion . Adhesion of water to the walls of a vessel will cause an upward ... |
Why are so many questions on here asked if most of them require just a quick google search? | That's a very good question. But you hold the answer. A simple google/reddit search would have revealed that this question itself has been asked numerous, numerous times here. So why didn't *you* do that? I'm sure you have any number of reasons why you just decided to ask the question without researching it first. Thos... |
Is there a reason why we get stomach ache when we eat/drink too much? | You can imagine your stomach and intestines wrapped with a bunch of stretchy cords. The cords detect how "full" the area is through their stretching or compressing. The three important factors are inflammation, loss of blood, or distension. Since you're made of squishy stuff bound together by more squishy stuff, your b... |
Why does Japan get to eat Coconut Curry Doritos and Strawberry KitKat bars, when we have the more diverse population. | It's the result of market research. I'd like to try those too but as long as people choose Cool Ranch over more unusual choices we're never going to get them. Shelf space is not unlimited, and it's especially a problem in vending machines. They only want to stock the most popular items of each type.Compared to the U.S.... |
How do they fake apps/operating systems in movies/TV | Usually you would want to do it in post-production because screens don't film well due to different refresh rates. They may have prompts on the screen if the scene calls for it though.There are people who are paid by studios to create the "OS" that are seen in movies and shows. [Mark Coleran] is one such person. The id... |
If something has its colour because light get deflected, does that mean that an object in a fully dark room has "no colour"? | Depends on what you mean by "has colour". A blue scarf doesn't stop having the ability to reflect blue light just because there's no light on it right now.What does a trumpet sound like when you aren't playing it? What mass does it have if you aren't trying to accelerate it? To measure any property, you have to interac... |
How did Skyrim keep track of everyone's actions, movements, interactions with the environment etc. The computation seems mind boggling! | Is it impressive? even in terms of an open world RPG, skyrim didnt do anything too special in that regard. If anything, it did a bad job. Most giant story elements barely change anything. You're the head of the mage college? people still tell you to go check the college out, etc |
Why didn't NASA astronauts (or anyone else for that matter) return to the Moon? | It's uninteresting. They went there to beat Russia, not so much for space exploration in itself. Just wait until we know how to make power out of Helium-3 though. They'll be all over the moon again. Edit: _URL_0_ |
If people with one eye have no depth perception, how come I still have it with one eye closed? | Your memory and brain compensates for your closed eye. So, while you don't have depth perception, you still remember relative distance of things based off of the past, and can reason how far away they are. In reality, you don't actually have depth perception. If you go to an unfamiliar setting, and have a friend put th... |
Why is it that whenever snow is stepped on it makes that muffled crunching sound? | The snow is made up of small ice crystals that are lightly stacked on top of each other. These crystals compress down under your weight, and as they pass each other, they scrape together, making that crunching sound.I remember many different kinds of snow from my childhood in Alaska. Some of the more interesting sounds... |
When I "google" passwords I use for various websites (usually porn) I get lots of hits for databases that include both my username and password - wtf? | If you use GMail, you can take advantage of the + feature. When submitting your email to a site, do something like this johndoe+reddit@gmail.com All those emails will go to johndoe@gmail.com but you'll be able to see the +reddit in the TO email address in the email. From then on, any emails you receive trying to scam/s... |
How does listening to loud music aid in hearing loss? | Loud noises damages little hairs in the ear, the more they are damaged, the less you can hear and eventually lead to tinnitus |
Why does 1080P video look better than 720P video on a 720p resolution? | When a video is compressed, there are typically many settings that can be selected. Resolution is one of them, but there are others which are arguably more important, like bitrate, which is the average amount of data that will be used to encode each second of video. Typically they are increased together, so the 1080p v... |
What would the Big Bang have looked like if you were able to view it from a great, great distance? | You could not have viewed the big bang from a distance, because it filled the entire universe, and occurred everywhere at the same time. It was an expansion *of* space, not an explosion *in* space.Shows display the big bang often as a 'spot' expanding outwards. Because the key is expansion, and they want to display thi... |
Why is the book "Ready player one" allowed to reference pieces the Creator doesn't have a right to but the movie isn't? | I think it's because of "likeness." You can namedrop characters for free, but you can't show their likeness because their design, the way they look, is copyrighted. In the book this isn't an issue, because you just namedrop and the reader imagines the likeness in their head. But for a movie they would of course have to... |
if an object is just floating in space is there a point where it stops moving or will it always be moving unless hit by something? | If it some how avoids being influenced from another object or gravity field it would eventually stop. Space isn't an absolutely perfect vacuum, but it's close. So this would take an extremely long time. |
What is the difference between sleep, being under anesthesia and being in a comatose state? | Sleep is a natural state where your consciousness mostly shuts down, allowing your brain to process. No one really knows what all it is trying to do, but it is necessary for healthy brain function. Anesthesia is chemically induced sleep, usually for the purposes of medical treatment. Under anesthesia, a person will be ... |
why when you put a wooden spoon across a pot does the water not boil over? | Any bubble that touches the spoon pops because it is so rough. That leaves a gap that the other bubbles fall into. Since no bubble can go higher than the spoon, the pot doesn't overflow. |
Why do goldfish bob for air/how do they use it? | You need a 20 gallon tank and an air pump to keep the oxygen level correct for the fish. Ammonia builds up as well and that makes them gasp for air since they can't get enough with their gills. I guess they can pull some oxygen out of air if needed but probably not enough to keep them going for very long since their ch... |
How does social security work and why is it such a problem? | The problem is only works due to the collective ignorance of the population. People believe that they have money in an account waiting for them when they retire. In reality they money that they are paying into the system right now goes to pay other people that are on the system. It is a ponzi scheme by definition excep... |
Why are dimes smaller then nickels? | I entered your query into a google search and got this: The coins retain their size due to tradition. At one point in time the size was based on the value of the metals. A nickel was made out of 5 cents worth of nickel. A dime was made out of 10 cents worth of silver. 10 cents worth of silver is smaller than 5 cents wo... |
Please explain the bill that republicans accuse of causing the housing/market crash | I believe you're referring to the [Community Reinvestment Act]. The CRA was intended to help low-income people buy houses by encouraging banks provide loans to them. These loans were backed by the feds; if/when a borrower defaulted, the government ate the loan. The CRA was a perfect scapegoat for Republicans looking fo... |
Why are conservatives fiscal plans considered to be the best choice when it comes to national economies. | You are likely paying more attention to conservative-leaning media. Nobody knows *for sure* the best way to fix the economy. It's possible for different people to look at the same set of evidence and come away with different conclusions. That's why elections happen, because there is no definitive right or wrong answer ... |
how come even after just wearing my glasses for an hour without touching them, they’ll still get smudged? | Your eyelashes may hit the lenses, leaving behind oils. And airborne dust may also get caught in said oils, further adding to the smudges noticed. |
What is the point of a number lock and scroll lock Button? | Number lock allows you to toggle between using the number pad to enter numbers or to navigate there are arrows on some of the numbers and other movement functions on others) Scroll lock switches the function of the arrow keys in many programs.

When we take medication, how does it know where to go to heal us or where we're hurt? Is there any possibility that goes to another place that it shouldn’t? | In true ELI5 fashion: imagine that every molecule of a medication is a tiny key- and by taking the medication, you release millions of those keys into your bloodstream, where they can reach the cells of your body. On the surface of every cell are one or more tiny locks- billions of locks. And by design, the keys match ... |
Why are credit unions apparently better than banks? | When banks generate profits, these profits are distributed to their shareholders. When credit unions generate profits, these profits are distributed back to their customers. Credit unions are run by the community, for the community. There are benefits to both sides. With major banks, you have greater "accessibility" to... |
what is NATO article 5? | I'm sure someone will provide a more in depth answer, but the overall summation of Article 5 is that if you attack on one member of NATO, you are thereby declaring war on all the nations that are in NATO, as well.It is a section of the North Atlantic Treaty, which founded NATO. It is the key provision and binds the mem... |
why standup is so much funnier and music sounds so much clearer when I’m drunk? | People mistake thinking getting drunk "changes you" what getting drunk actually does is depresses higher brain function and reaction time and such. This is because alcohol is a depressant, meaning it depresses your senses and processing speed. Because of the reduction of higher brain function you are left with more bas... |
How do animals who were supposedly extinct for hundreds of years somehow reappear today? | They don't exactly reappear; we just eventually stumble upon a group of them that had been there all along without us noticing. |
why do people on the Internet generally prefer vehicle license plates to be blurred out when they are constantly on public display anyway? | Being on public display is not the same as putting it out as a sitting duck in front of a bunch of anonymous Internet usersLicense plates are on public display in the area in which you drive. Putting one on display on the internet, however, makes it available worldwide to an unlimited number of people. In the real worl... |
Why can't counterfeiters just make old currency? | Counterfeiters don't just make one or two bills. They make hundreds or thousands at a time - the equipment is expensive & the risks are too high to bother with small numbers. So, sure, you could pay with a single 1988 $50 bill. When somebody's got a giant stack of them in uncirculated condition, it becomes harder to pa... |
How do artists pay taxes when they have world tours? | They owe taxes to each country they perform in. Since it is pretty easy to figure out what they made form each individual performance it is fairly straight forward to calculate their income earned at any given venue. |
Do chimpanzees respond to pheromones of period blood? and how do they? | There are no pheromones in "period blood" as it's just blood. During the period, shredding of the uterine lining, copulation would make no sense, so what good would pheromones do? Pheromones are hormones, and there is no scientific evidence that pheromones are used by humansI can't account for the reasons chimps may re... |
Brain wave manipulation through music | Firstly, when you read about that stuff, you're reading about binaural effects where differences between the ears of the same musical signal will somehow affect the brainwaves of the listener. It's questionable at best, and straight up lies at worst. The only scholarly articles published on it are published in journals... |
The whole net neutrality that's going on now. What do they want? What will probably happen? What's going to happen to the internet? | There was [a HUGE thread] just the other day that you should read through.

has Utah really banned pornography? | No. All they did was declare it a "public health crisis." It doesn't actually do anything about it. It's a non-binding resolution.I'm not sure but I just wanted to voice agreement that this is a place where government does not belong.The only thing I found was a senator spouting some nonsense about the Internet violati... |
In theory, what would happen if a woman consumed an entire 24-day pack of birth control pills at once? | It would not work like a morning after pill/ emergency contraceptive pill. Someone more qualified can answer precisely what would happen but if that's where your line of thought is going please go to a pharmacy. The woman could get very ill. An overdose could result in large blood pressure changes, huge headaches, blee... |
Why is a grey and white checkered background used to symbolize transparency in image files? | It's a very distinct combination that shows edges very well no matter what the color of the non-transparent part is. It's basically there to say "look, I'm transparent here. Don't mistake me for anything else!"Probably because photoshop has been using it for so long. A solid color would be hard to distinguish as transp... |
How does a life support system specifically exchange carbon dioxide into oxygen/hydrogen? (On a space station or shuttle, I.e. ISS) | CO2 is removed using molecular filters. "Dirty" air is passed through silica gel to remove the moisture, then passed through a molecular filter that lets the smaller oxygen and nitrogen molecules pass, but blocks the CO2. The CO2 is then vented overboard. Oxygen is derived through electrolysis - electricity is passed t... |
Why does butter on toasted bread taste different than butter on non toasted bread? | Browning the butter actually makes butter taste sweeter as oppose to its usual savoury taste. So I would imagine it's along the same lines Edit: to make brown butter . heat a skillet on high heat and place a stick of butter in it. Turn down to medium heat and wait for butter to melt. When it becomes caramel coloured an... |
Why is Spain seeing deflation? | Domestically, Spaniards have less money to spend, because the recession has been so severe there. So people are really penny pinching, so prices are constantly getting forced down. Essentially, money is getting pulled out of Spain . Why invest in spanish banks, when you'll get a better return in Frankfurt? Since there ... |
How do random number generators work in for example Matlab? How can a computer "choose" a random number? | They don't. Computers use something called pseudo random generators. They pretty much just have a list of thousands and thousands of numbers which seem random enough for all intents and purposes but actually they have some underlying pattern. |
why our perception of time seems to speed up as we age. | Mainly because you've lived longer, and everyday is now a shorter proportion of your total lifetime. When you are 5 years old, summer vacations seem like a really long time because they have lasted 5% of your entire lifetime. By age 30, they are only half a percent etc You also experience less and less new stuff in you... |
What is the difference between correlation and relation | Relation is how things are connected. Correlation is how things are connected when that relationship goes both ways. i.e. the relationship between them is one of dependence on each other. Imagine you have a glass and a carton of orange juice. How much juice you pour in the glass is related to how much juice is left in ... |
Why are airplane black boxes still needed? Why cant aircraft send information in realtime? | Feasible but expensive. And any transmission can suffer from interference and other disruptionsIf an aeroplane is able to wirelessly send signals to a satellite, more often than not, it is not under any crisis. It is those messy situations where the signals all get cut off, and/or the harware stops working, when we nee... |
how does fasting blood sugar work? | You can drink water. Measuring FBS is a good way to assess your body's regulation of blood glucose via the hormone insulin.

When you touch really hot water, why does it feel cold? | Scientists aren't exactly sure. There are special nerves just under your skin called thermoreceptors which detect temperature. When activated, they send messages to the brain that say "this is hot," or "this is cold." For some reason, temperatures above 113 F sometimes fire off the "this is cold" response. It's most li... |
how do zits form, and why does popping certain zits hurt like a bitch (lip line) and others don't (forehead) | There are different kinds of breakout. Whiteheads and blackheads are simply clogged pores; the oil in the pore is either blocked, trapping the bacteria in the pore, or it is exposed to air, where the bacteria oxidizes and forms a whitehead. A pimple, or zit, when the bacteria deeper down in the pore becomes infected an... |
How does someone like the FBI recover info from a hard drive even after formatting or even more seriously using a tool such as DBAN to wipe the data? | This depends a lot on the drive technology and the way the data was protected and/or erased in the first place. The recovery relies on the fact that although we talk about zeros and ones, the physical underlying medium may have certain ranges for representing 0 and 1. The methods for recovery may be software related or... |
Why is "civility" a big thing on Reddit now? Why do comment sections get locked if people say unpleasant things? | It's likely due to the fact that the current political climate has led to extremely polarised views, and lots of pointless childish name-calling between them. It makes it all a bit useless when you want facts or real discussion, and instead get people being called cucks or racists all the times. |
I get freckles seasonally. I'm wondering if it's similar to some birthmarks that are only visible when you are more tan, or if you get new freckles every year? | My freckles are the same, and I'm no expert at all so please don't only take my word for it because I only studied it for a little bit, but you have melanin deposits in your dermis. These are your freckles. Sometimes they expand with exposure to the sun, but most of the time, they remain the same. Melanin in the ingred... |
Why do some YouTube videos that show episodes of TV shows have unrelated borders in them that take up a third of the screen? | There are 2 reasons, the first is the uploader is trying to avoid the video being automatically flagged as copyright, Youtube has an automated system that can detect copyrighted content, an easy way to trick this is to either frame the video or to use stabilization . The other reason is because Youtube has a very big p... |
Why do we sigh when we are sad? | When you take a deep breath, it stimulates your central nervous system in your chest and releases calming hormones. This is also a reason why people feel relaxed when they smoke, they are doing deep breathing exercisesI saw a similar question on here before. Basically the answer was that a sigh is like an emotional res... |
When I stare at the carpet, the area around my focal point appears to move almost like a liquid ripple - what is happening? | I get this too! Especially when looking at the sky. Would love to know whyI get it when staring at a point with rapid color changing or general movement like driving.I've experienced this before. It's usually with a very short shag carpet at my SO's apartment. No idea what it is, but you're not alone! I assume it's bec... |
There is currently an ant infestation in my 17th floor office... How the hell did they get here | Ants are very small and thus have a very low mass. Gravity does not overcome the force of friction that the walls give against their feet because their mass is so small. That's why they can climb 20 stories straight up. A more probable idea would be that they have built a presence in the walls of the building over a fe... |
How exactly are modern wars profitable to a country? | To a country? Usually they aren't in a monetary sense. Companies that make the parts that go boom make most of the money, along with military contractors.

When people pay fines (speeding, littering, etc), where does the money go? | The city where you got the fine in. That city made laws that are punishable by a fine. Money goes to them. |
How do voices 'merge', to make a group of people louder than a single entity? | This is the result of addition: If you turn on 100 light bulbs you will get a brighter light, than if you were to turn on only one. Each one is still only emitting a small amount of lumen individually, but collectively they add up If you open a tiny hose of water, you get a small steam. If you open 100 tiny hoses, you ... |
In General and Special Relativity, what is "it" relative to? | In the case of special relativity , the reason for the name was that the theory states that all motion must be relative. The Earth has different speeds relative to the Moon, the Sun, the center of the Milky Way, and you. Special relativity says that it is impossible to determine an "absolute" or "universal" speed of th... |
the people on the internet who say that we should all adopt gold and silver backed currencies instead of "fiat money" | There are people who don't believe in the validity of fiat currency. They say that it's not backed by anything real, that it's a collective illusion. To a point, they are correct, but it's an extremely functional collective illusion. Such people believe that instead of basing our monetary system on modern economic theo... |
How do police find files that criminals have deleted from their computers? | A file basically consists of a certain arrangement of bits on your hard drive--the pattern is what holds the information. When you "delete" a file, those blocks are marked as available for writing in the filesystem, but the pattern that was there doesn't change until you actually write something over it. So a typical f... |
How does Samsung Pay work without NFC? | It's called Magnetic Secure Transmission. Samsung bought the technology from a company called LoopPay. When a credit card is swiped, the terminal reads information from a magnetic stripe on the back of the card. MST sends out a signal with the same-ish information that the terminal is looking for. It won't work right w... |
What will happen to Earth when the magnetic poles switch? | No reversal in the past has been correlated with any kind of mass extinction. The overwhelming majority of high energy particles are deflected not by the magnetic field, but simply attenuated by our dense atmosphere. Perhaps the biggest threat is that to our satellite network; there's problems already in realation to t... |
This is just a reminder to please search before asking your question here. | This reddit is just like a real five year old, then. They ask the same question over and over and over. source: I have a five year old kidThe reddit search function limits to exact wording, so it might not work too well.

why can we see things with little light but my camera photos are either totally dark or too bright with a flash? What is the difference? | The human eye has an incredible dynamic range that we are just not able to reproduce with a camera. Dynamic range is the visual perception of the difference between the dark and well-lit areas of a scene. Our eyes are able to distinguish both dark and light right next to each other. Cameras are typically better equippe... |
Why are there so many controls in a plane cockpit? | so non-pilots dont go in there and try to fly away with it.Allowing manual control for every system in the aircraft allows for a lot of non-standard operations in emergency situations. I'm not as conversant on emergency situations for planes but I think the principle remains: If it would be beneficial in ANY situation ... |
Why do I get goosebumps when I hear a beautiful piece of music or watch an amazing bit of film? | When you hear a beautiful piece of music your "sympathetic nervous system" gets stimulated. This causes your body to experience a rush of adrenaline, and also causes something called the piloerection reflex, which makes your hair stand up. It is akin to the same primal fight-or-flight reflex which causes a cat to eithe... |
What are some examples of things that would be acceptable under Thomas Hobbes' system which wouldn't be allowed under Locke's? | Both are supporters of a strong central government, but where Hobbes\' leviathan describes the reasons for forming and philosophy of maintaining an absolute government , Locke's work focuses on a religious rational for killing a particular sort of corrupt king. Hobbes has strong feelings about rebellion, but he also in... |
W How do they design Paper Currency? | There isn't anything special to it, just like security in a lot of other fields. The goal is to make it difficult, time consuming, and expensive to replicate as possible. The cultural thing is just to make it look nice.

How do aquatic animals know how far they should go down in the water? ex. Blue Whales can only go so far down, what prevents them from going further? | Probably "similar" to the feeling you get when holding your breath past what's good for you. Your body just knows what it needs and will tell you when you are taking risks.Well, to answer the latter, that would be pressure. The open body cavities in their sinuses and especially their lungs would have to deal with great... |
The current white supremacist and neo nazi situation in the United States | Neo Nazis and white supremacists still occupy the extreme minority in the United States that they have for as long as they've been a concept.

Humans have shamed ... |
; If an insanely loud sound lasted 1 billionth of a second, would we be able to hear it? | No, you wouldn't be able to hear it. Sound is fast change in air pressure from positive to negative. Most humans can hear in a range of 20 to 20,000 Hz, or changes in air pressure per second. So if you were to hear a loud sound that lasted only 1 billionth of a second that wouldn't be long enough for the air pressure t... |
Who Glenn Beck is and why he is so controversial. | I'm sure there are some YouTube videos of him available. You really should watch one if you want to truly understand. He spouts very, very politically conservative propaganda. He distorts facts past the point of recognition to fit his conclusions, and paints anyone who is not as nutty as him as an evil person with a se... |
What were to happen if NK shelled Seoul and killed a few thousand people, but threatened to use nukes on the US if they intervened. | South Korea would wipe North off the map. South Korea spends more on its military than North Korea's government spends, total.There are a crap ton of factors, but I think it would go something like this. Seoul is severely damaged. An enraged and rabid South Korea wants more than just blood and launches damn near everyt... |
How do astronomers figure out what elements are present on celestial bodies light years away? | The astronomers look for things called **spectral lines**. This has nothing to do with ghosts, rather the word "spectral" is derived from "spectrum", meaning light over a range of wavelengths . So in detail, this is how it works: Scientists discovered a couple of centuries ago that different elements absorb and/or emit... |
What good is a social security number? What things can I get that I couldn't get without one? | A job, tax refunds, a bank account, enlistment in the Military, Social Security benefits, student loans, and many other things. Granted, there are some other ways you can get things done, like paying your taxes, without a SSN, but the process of convincing the powers that be that you don't have and don't want a Social ... |
What Is Ethical Egoism? | Ethical egoism is the idea that you only ever act in your own self interest. For example if i give to charity, its because it makes me feel like a good person.

Why are conservatives considered "the right" and liberals considered "the left"? | [It all goes back to seating arrangements during the French Revolution]. The National Assembly took sides, with the royalists on the right and the revolutionaries on the left. Newspapers just referred to them as the left or right occasionally, and it caught on.Liberal is a broad term, in other countries it may mean cen... |
Why is the water level higher inside a straw? | Here are some ideas: 1. The atmospheric air pressure is pushing down on the drink. 2. Capillary action is the result of the adhesive forces between the straw and the drink. Since there is comparatively a lot of drink touching the straw inside of it as opposed to not touching the straw, the adhesive forces have the liqu... |
Here on Reddit, we see a lot of "Scientists have discovered..." posts. Why do I never see any instant results from something like this? | I guess because of exaggerations, and title clickbaits. Let's say some laboratory made some small discovery which helps them understand a disease more, but there's still a lot of uncertainty and problems on the way to curing it. But it somewhat helps and they are one step closer now. Now they make an article, article g... |
