Why isn't water a super conductor? | Electrical conduction is heavily influenced by the movement of free electrons, or electrons that are not used on bonding between atoms and are able to conduct . Metallic materials such as copper and aluminum have a high amount of these free electrons. Another effect on conduction is the 3D arrangement of atoms in a sol... |
Why do Americans hate cursive? | Because it's impractical a skill. Everyone's handwriting is different, and some people, like me, have near-illegible handwriting no matter what. Not to mention it's forced on people, and anyone in adult life who demands something in cursive will be laughed at and told to go fuck himself. Many forms mandate that you sho... |
Where I live, I pay a water company per litre of water I use. If that's the case, what's so bad about what Nestle is doing with water privatisation? | You don't pay water company. You pay the water utility, which is a branch of the municipal service of the city/county. It's not a private company that's trying to make a profit off you. |
Why is CPR for drowning different than CPR for people who collapse from heart problems? e.g rescue breaths are recommended for one but not the other. | Question has already been answered pretty well, but I can provide a relevant aside. The training I receive as a police officer in the UK differentiates not only between collapsed/drowned adults, but also between adults and kids. For *all* kids we begin with breaths. The rationale is just one of likely causes. If you lo... |
Why is ISIS battling for territory and land? Wouldn't it be more effective to keep building army and not trying to take over key areas, ultimately exposing yourself? | Also, they aren't an army. They aren't thinking strategically like a real army would. They've set a goal of making an Islamic nation by force, with no real thought as to how they will actually do it whilst being attacked by real military powers. |
Why is that when you blow a balloon too hard, little air pockets appear inside your mouth just below your ears? | Audiologist here :) I'm going back a few years to my training so bare with me.What you are doing is forcing air through the tube that connects your throat and middle ear. There is only limited space in the middle ear so forcing air in can cause the ear drum to bulge outwards pulling the surrounding area potentially cau... |
What happens if I don't sign up for Obamacare before the deadline two weeks from now? | Just signed up my folks for this yesterday. late 50's with a small business of 4 employees. they were paying 700 bucks a month for shitty insurance that barely covered anything. Now starting april 1st, they pay 260 bucks for both of them. Over $5K in annual savings. Thanks OBAMA.I live in Oklahoma, have insurance throu... |
is it better to have a shower in the morning or at night? | I would say it depends when you are most likely to be in contact with other people. I tend to shower before I go out, sometimes that's in the morning, sometimes the afternoon and sometimes the evening. |
Why is there only so few female inventors? | Also, female inventors aren't given the same social standing as male ones. [Jeri Ellsworth] is a brilliant electrical engineer, but who knows about her? Nearly nobody.Maybe it comes from the past when men worked and woman looked after their children, the house etc? |
Why can US celebrities openly admit drug abuse and suffer virtually no consequences? | Ok Wiz Khalifa blatantly [possesses weed in music videos]. You can also see him smoking at 3:12 in that same video. I've always wondered how he of all people doesn't get into trouble. Can someone please explain this to me?", 'Because admitting to using drugs is not the same as having them. I could admit to murder and p... |
Why is Florida the site of most, if not all shuttle launches in the U.S? Why not something with more consistent weather like Arizona? | They want the rocket to take off and fly over water so if it goes down it won't land on anybody's house. |
Why is it that we talk about establishing a civilisation on Mars but not the Moon? Like we've already been to the Moon. Why is this not discussed? | Mars has more resources than the moon. It has water rich soil and a nitrogen rich atmosphere. Mars is colder on average than the Earth, but there is sunlight for solar panels and Equatorial temperatures can reach 20°c in the Summer. The atmosphere is thin but offers protection from radiation, unlike the moon which has ... |
Why can't our teeth heal like our skin and bones? | You can, and it's called remineralizing. However, it doesn't fix major cavities/broken teeth.Dental Assistant here. My boss figured out how to remineralize enamel. If a cavity has not yet reached the Dentin, we can fix it without a filling. We use ozone gas which is pure oxygen to sterilize the tooth. Because it is a g... |
what actually causes genetic issues if breeding pair are for example siblings? | From the sociological standpoint, part of the reason the taboo cropped up in the first place is because incest can be a recurring problem. Genetic deformities and conditions are more likely to crop up over time if siblings keep procreating with siblings, and that's more likely to happen in small breeding pools - such v... |
If captchas look at your mouse movements to tell if you're a bot, how does it work on mobile devices? | All the top comments in here are correct. As well as JavaScript being able to access gyroscope data from your phone. Especially useful if you're holding your phone in your hands as the gyro data will change all the time which the captcha tool could also use. We'll never know the exact algorithm they use, cause if we di... |
Why can't I remember any memories before the age of 6 or 7? | You can't? I can. I just heard Orchestral Manoeuvres In The Dark's 'Joan of Arc' on the radio and I had a very vivid memory of watching the video clip at home when I was 3-4 years old |
What happens to a persons assets if they are arrested? | I know your bills follow you to the dog house, you're expected to pay them no matter where you are. Or so I've heard on Reddit.It depends on how dirty the cops are, they may just have their assets stolen as civil forfeiture |
Why is voting for a third party candidate in the United States "Wasting your vote"? | The 2000 US Presidential election is a good example of this. The election was very close, George W Bush defeated Al Gore 271-266 electoral college votes. The state of Florida with its 25 electoral college votes was won by Bush by a few hundred votes. Had Gore won the state he would've won the election. Ralph Nader, the... |
How do they find a bacteria in a restroom? Are Airport Bathrooms Spreading Antibiotic-Resistant Bacteria Globally?A rare strain of MRSA originally from India has been detected in a Paris airport bathroom. | Because public restrooms have thousands of bare hands touching them every day. All you have to do is swab the door handle with a piece of cotton, put it in a petri dish, and see what grows. They know to look in a restroom because it's a very public place with many many bare hands touching it, which means they can get a... |
Why aren't people woken up by their own loud snoring? | A couple of times, when I've been dead tired, my snoring has actually woken me up. It's usually been 2 minutes of hitting the bed. Am I the only one? |
Why is Venezuela so destroyed at the moment? | From what I understand the majority of their economy relied on oil, Venezuelas pretty much only decent resource. When the arse fell out of the oil market some time ago countries that relied on it also crashed. The market recovered somewhat, Venezuelas economy did not. I think there are also the usual problems with corr... |
Did we always instinctually know that sex led to reproduction, or was there a point where someone put it together? | There for sure had to have been a time before we were smart enough to figure that out. It's not like there's any immediate evidence that the woman is pregnant. |
EL15: Why is it so hard for a woman to have a natural delivery after a C-section? | It depends on individual cases and it will also depend on what the reason was for your first C-section. For example, if you had an infection and that was the reason for your first C section, and you don't get an infection this time, there might be no need. The main reason would be that your uterus has already been cut ... |
Why do poachers hunt animals to extinction? | I'd say it is a perfect example of the [tragedy of the commons[. In situations where resources are shared, it is easy for individuals who are looking out soley for their own profit to collectively harm the public resource. The same thing happens in many other ways, such as air pollution. No one thinks that their small ... |
What is the point of spending years of your life developing software when people will just download it off of a torrent site for free after it's released? | You're banking on enough people wanting and being able to do the right thing and pay for the software. And judging by the many companies/people that manage to pay the bills by developing software, it's not necessarily a bad bet. |
What is an executive order in US politics? | The US government is divided into three branches. * Executive - the president's office.* Legislative - Congress* Judicial - the courts In the case of the executive branch, the president can push through executive orders as laws and they kinda . just happen. It's the rule now. However, he cannot change the constitution ... |
Do average people really produce $115,000 of stuff per year, yet take home only $26,000? | one thing youre forgetting, all companies have the basic requirement to make money and grow, this means that a good portion of it must be re-invested into the company. As I am starting a small firm with some friends we've been studying company structures and for small companies it can be as much as 75% of total monies ... |
how wireless charging works and why it can/can't be put in roads to power electric cars? | I wish a mouse manufacturer would build charging into a mouse pad so we could have wireless mice that don't have to be plugged in to charge or require a battery swap.Way too many bad assumptions being made in this thread. Wireless charging CAN be used to power electric cars. I saw the demo for [this news piece] . **Tl;... |
Why do we get a feeling in our chest/stomach when we have sad/bad thoughts? | What if I told you that you get sad/bad thoughts because you get a feeling in your chest/stomach? Seriously, more research is suggesting that psychological feelings of fear or other negative emotions are often triggered by physiological factors. We don't run away from a big bear because we're scared, but rather studies... |
What is happening when you are "blackout" drunk? | Well, I think, basically your brain stops recording what goes on, you don't forget what happened, it just wasn't even logged in the first place. |
Why indigenous women in Canada have been murdered or gone missing at such a high rate? | Extremely high rates of drug and alcohol addiction have ravaged many, if not most native communities in the country. I saw this first hand working in a rehab centre. The government pays for their rehab, pays for their education, and basically guarantees them a job upon graduation. But 99% of the time, it doesn't mean a... |
why do we have a constant "R" in the ideal gas law? | The formula is about a relationship between to different basic units of measurement. We need the constant to convert from one unit to another. PV = nRT P = pressure in atmospheresV = volume in litersn = number of molesT = temperature Consider the units. PV is in = /nT is in So either we need a gas constantR = .08206 / ... |
Why can't we move our eyes in one smooth motion unless we're focusing on something? (fx. car that's moving) | This happens because when your eyes are moving, you can't actually see anything. It's all blurry. But we have evolved so that we can move our eyeballs in our head to keep them still enough to get a good picture while we move our head around. You can see the disadvantages of not being able to do this in other animals li... |
How do planes and jets tell when they have a missle lock on them? | For radar guided missiles, the search, acquisition, and target illumination modes of the radar source have different frequencies. these frequencies are known and are programmed into the radar warning receiver's database.I always thought it was the guy in the back seat . "THEY GOT A LOCK ON US!!"', "What's a heat signat... |
Why do 2 windows allow better airflow? | It's pressure! Blow into an empty bottle, you can only fill it so much under sea lvl pressure, then the air will stop entering the bottle. Now cut a hole into the sides or back end, see how it flows. You reduced pressure.Because air can freely go through the room instead of going back out the same way. That leads to be... |
Why don't more people just buy generic drugs if they are the same as the expensive ones? | they usually do. but a lot of drugs aren't generic. the manufacturer gets a 12 year period for patent before any generics are allowed to be made. so during this period, they jack up the price and make the monies before generics drop the price way down. |
If everyone in the US is required to have healthcare, why do we still use open enrollment periods? | The real reason for Open Enrollment is to prevent you from switching to better insurance right before claiming you're sick. If you pay a super low rate all year and have a crazy high deductible and then get chest pains, you could switch to the better insurance and then go see your doctor. |
Is it beneficial in any ways to mature early/late compared to others? | Plot twist: OP is actually five and is genuinely concerned. Jokes aside, I remember one finding that indicated that, at least socially, early maturation tended to be beneficial for boys and problematic for girls. The way tweens and young teens treat or refer to developed bodies is heavily moderated my gender. Honestly,... |
Why have shields never been used in warfare since the popularization of guns? | On top of all the reasons listed below, there's a big one: most people on a war battlefield aren't going to be killed by small arms fire. They're much more likely to be killed by an artillery shell. While a ballistic shield may protect you from fragments to the front, it'll do bugger all against the blast or a shell la... |
Why do fingernails turn white at the tips? | The nail itself doesn't change colour, it just looks different where it is still attached to the finger, because you can see the dark pink flesh through the translucent nail |
How can grocery stores get away with selling virtually the same product as a major company just by switching up the name up and calling it store brand? | Most food items are just arrangements of ingredients that cant be copyrighted/trademarked. Take Kraft mac and cheese for example. Its elbow macaroni and a cheese sauce. You can't copyright that. The EXACT formula is probably a secret, but everyone knows what's in them generally. Food scientists can easilly reconstruct ... |
Please elim5: uncertainty principle (Heisenberg principle) | There is a good joke about the Heisenberg principle. It's told and posted often, but here was one from /u/jokes about a month ago. _URL_0_ |
What took place in the facebook experiment. | So . can I use being a victim of this experiment as the reason I didn't get likes on a selfie of me with my cat? |
New Horizon is travelling at 31k mph. How is it possible to capture a photo in such low light conditions while moving at this speed? | I saw somewhere in [the NASA IAMA] that they take many shorter exposure photographs and combine them, because it doesn't require the probe to be as stable. I can't find the exact link, it's likely in one of the 'load more comments' bits. It's moving at 14,000 metres/second. A decent consumer digital camera can take a 1... |
Why do actors (especially popular ones) get any say in the script or general film making process? | Because making a movie is a collaborative process. Unless a director is a control freak, it's generally expected that they'll take input from the actors. Also, very often things read better on the page than they come across when you're actually acting them out. That's why writers are given the advice to read their dial... |
Why do fast food and casual dining places need to nickle and dime us on some things but not others? | My wife works in supply chain at a larger fast food chain in the US. I was told that the landed cost of a dipping sauce is about 20-23 cents. They charge 25 cents to the customer for an extra, so they aren't making much. Knowing this has opened my mind about paying for extras. |
Why do people from China keep trying to sign into my Google account? | If you have a smartphone I would highly recommend setting up 2 factor authentication. It makes it so that two passwords are required to login. One being your usual password, the other is a 6 digit number that changes every 30 or so seconds. You setup Google's 2 factor authentication app on your phone in order to genera... |
Why do people keep saying the bombing suspects "are from Chechnya, not Russia?" Isn't Chechnya in Russia? Wouldn't this be like saying "they're Texans not Americans?" | It would be like saying they were Faroese, not Danish; Basque, not Spanish; Quebecois, not Canadian; Tibetan, not Chinese; etc. They're formally part of a country despite not wanting to be.It's pretty much *exactly* like saying "they're Texans, not Americans" somewhere around 1850Pretty much the same reason why we say ... |
Why does my phone reception strength vary so much when the phone is completely stationary? | Pretend you're taking a bath. Each Barbie doll you play with in the water is like a cell phone on the network, the water level is the noise floor, and your glistening, wet five year old body is the signal. As more Barbie dolls are added to the tub, the water level increases and less of your body can be seen. This is on... |
How can we estimate that the golden record on Voyager will last a billion years? | Space is not empty; there is dust everywhere. On average, there are about 0.1 to 10 particles per cubic centimeter. It's mostly hydrogen which isn't a big deal. Over time though, the effects of this constant barrage of dust will degrade the record to the point where it becomes unplayable. |
The motives behind banning any kind of research | If you know the answer and you don't like it, chances are you don't want people to ask the question. |
Would it be possible to make a video game where the graphics are actual pictures from the real world (not animated). | You can't make a 3D environment like that, but side scrolling games sometimes had hand-painted backgrounds. The same concept applies to photographs. |
How do car manufacturers get away with claiming fuel economy figures that are entirely inaccurate/unachievable in real world driving conditions | They use the rules of the tests to their advantage - just like F1 teams skirt the edges of the rule book to get a faster car that's still legal. Rules are always open to interpretation and always will be. |
How can we sometimes tell someone is looking at us and turn to meet gazing eyes? | It is actually deeper than just a coincidence Try social experiements, its more than simply catching someone's gaze. _URL_0_ |
how did cavemen take care of their teeth without toothpaste and dental supplies? | Bacteria may have evolved to attack our teeth at the start of agriculture. Cavemen possibly didn't have dental issues in the same way we do. Edit: I think I read that somewhere. |
Why is advancements in gun technology quickly protected by the 2nd Amendment but what's considered persoanlly online property isn't protected by the 4th Amendment? | The 2nd amendment protects your tight to own something, it's not difficult to determine what is ownership or if a particular item is one of the type that you are protected to own. The 4th amendment protects you from unreasonable search and seizure. What is reasonable, however, has been under a LOT of debate; however, c... |
How is paid suspension even a punishment for police officers? | Paid suspension is not really intended as punishment but to avoid prejudicing an investigation or creating a possible conflict of interest, although it has not been proven that the officer in question is either guilty or innocent. If they are guilty but kept keep their full job during the investigation period they can ... |
why is it that in my dreams I can never hit someone/something hard? It always seems like I'm physically restrained. | I got bit by a dog in one of my dreams, it didn't hurt, though it did scare the shit out of me", 'I have the same thing. Or more often that I am being chased and cannot run. Yet I am also constantly dieing in my dreams as well |
Would the human body grow any differently if it was conceived and born in zero gravity and what would these differences be? | Quite probably, although we haven't performed this experiment. But it's worth noting that the human body undergoes fairly rapid changes in orbit (which admittedly is not really a 'zero gravity environment.' At the minimum, our skeletal and muscular growth is profoundly affected, due to the lack of stresses we experienc... |
When watching TV with subtitles, explain why our minds always (seemingly) choose to read text rather than just watch and hear audio? | For me it's because the text comes before the actual dialogue. Why wait to hear what they say when you can read it first?", 'I only use them for times when I cannot understand the spoken dialogue. Brits are sometimes hard to understand depending on their dialect, and they use words which I do not recognize. Sometimes t... |
how does the restaurant get the tip from my card when they have already swiped it? | In the states , is it not common to punch the tip amount straight into the terminal when you pay by card?", 'Short answer. All payments in an EDC system are finalized when the batch is settled at the end of the business day. Until that batch is settled, all payments are adjustable and when a tip is inputted into comput... |
I hope this isn't too obnoxious... ELI5 The 2012 US Presidential Candidates | Well son, there are two political parties, a mommy party and a daddy party. The mommy party is the Democratic Party. They want you to do well, but also want to make sure that the government will always be there to take care of you. They believe the government should always be involved and help you make the correct deci... |
What is hyper inflation? | I have yet to see a proper layman's term explanation so I'll give one. The more money a government prints, the more diluted the value of its dollar becomes. This dilution causes you to need more money to achieve the same purchasing power you had prior to the government printing the money. Hyperinflation is this on a la... |
The apparent increase of police shooting unarmed people | In the past, the cops would just lie or lack of video could shed enough doubt about what went down. Now, between dash cams and body cams on officers and everybody carrying smart phones that can shoot video, there's a much greater likelihood of video evidence. And once we've got some proof of what actually happens, then... |
Why can I eat an entire chocolate cake in one sitting? What happens to all the surplus energy? | Ok, so 5000 kcal in a sitting. There are about 9 kcal per gramme of fat according to my food-scientist-Ph.D. girlfriend . So that's 555 grammes of fat. Fat has a density of 920 grammes per liter, so that's 6 dl of fat. Now let's assume this fat is spread out evenly over your entire skin surface, which is about 2 m^. Th... |
Why does youtube buffer videos in all ¨P's¨ but when i'm watching porn it works flawless? | It has been said that your ISP is actually using a different server to route YouTube videos and it can't handle the load. I wish I knew the terminology to describe this. There is a fix for it as well, but I am of no use. I found it a while back with google. Check this out_URL_0_ |
Why can't we order donuts like we order pizza? | Although there are places that deliver donuts, it is pretty rare. One reason is that it is harder to make money delivering donuts. Many times when a pizza delivery guy leaves the store to make a delivery run, he is delivering 2-3 orders to different locations, each order is $15-20 after delivery fees. I don't eat many ... |
How can a country survive without government? | There aren't really any historical precedents and the closest contemporary examples sure don't look good.A structure ballistically similar to a government emerges. A person or people are at the top, usually the people with the most guns, and ranks, levels and hierarchies trickle down all the way to the bottom. Somalia'... |
Why does everyone hate Comcast so much? | Comcast is a rats nest of slapped together bureaucracies that don't interact with each other and provide unreliable service. Because most people have only one or two real choices for who provides their internet and TV, Comcast has no incentive to spend money to make their company work better when it would result in no ... |
Why are there rules on war? | My take on it is this: If you use whatever means necessary to eradicate your opponent then that is inviting them to do the same to you. Also, imagine that if a country went to war with another and used nothing but chemical weapons, but *lost*. Just imagine how much worse that country's inhabitants would be treated by t... |
How was Binary Code "discovered" in the 1600's? What were its applications? | Binary is just a number system based on 2 symbols instead of 10 symbols. Questioning assumptions about why we do everything based on 10 is a pretty natural question. It's not at all surprising that a mathematician investigated the concept a bit without any practical applications. It's very common for them to reduce thi... |
If rounds can easily pass through car doors, why do police use them as protection? | In addition to the other answers, some but not all police cars have ballistic panels in the doors. It's like another thicker layer of bullet resistant vest, and it can stop some rounds, and at least slow down others. |
What caused college degrees to become equivalent, or have the perception of being equivalent, to what high school diplomas used to be? | 1. The bar on high school education has been dramatically lowed over a period of many decades. Political, economic, religious, otherwise ideological forces have conspired to impose their wills on curriculums which has lead to entire subjects being eliminated from diploma requirements and questionable changes to what in... |
Could I live on a diet of protein shakes and vitamin supplements alone? Why not? | [Supposedly] but I wouldn't want to. Fiber and all essential micro and macronutrients would have to be included for long term health. I think I'd literally get sick of it though. |
Why are all the celeb naked pictures allowed on reddit but there was such a drama surrounding Zoe Quinn? | Well the main point about the Quinn thing was the danger of doxxing/a witch hunt. There is/was a lot of anger directed at her, and users on reddit and other places on the internet have been know for finding out private information about people, sending them death threats via PMs via PM or their phone, sending SWAT team... |
How are train engines able to pull enormous amounts of cargo? | I'll also add that it doesn't take to much effort to move a fully loaded rail car. You can actually move single rail cars by hand with a rail car mover . Also, trains take forever to get up to speed. I've actually driven one for a short distance before and acceleration is pretty slow. |
how do hunters do more for the conservation of species than anti-hunters? | Hunters buy hunting licenses which are used to pay for programs to ensure that those species do well. The hunters themselves can also be important to prevent overpopulation by declaring it hunting season when there's too many animals. |
Why is facebook stock falling? It's not like people have stopped using Facebook and they still make a profit. | Let's just back up for a moment **What is a stock price?** It is a ownership share in a company. It is a small portion of the value of the company. If, hypothetically, a person wanted to buy all the shares in a company, that is at least the price they would have to pay, just as you wouldn't typically resell your concer... |
The controversy around the Kennedy assassination | An interesting theory [states that Kennedy was not Lee Harvey Oswald's primary target]. There is no proof either way, otherwise there would be no controversy. The evidence known as of now, leads me to believe that Lee Harvey Oswald was the lone shooter. But, that's just, like, my opinion, man.Jack Ruby apparently kille... |
What would happen if everybody took all of their money of their bank accounts | A bank never has enough cash to cover all its accounts. By law, the biggest of banks are only required to have 10% of the money that's on the books available for withdrawal. Smaller banks don't have a minimum at all. |
of the sun blew up we wouldn't be able to tell for 8 minutes. Would we be dead before we knew? Or would we be able to watch the sun explode? | I'd like to add some other things to consider. Our sun is kind of an average star and it's future doesn't involve explosions. In about 4 billion years as the hydrogen fusion winds down, the outer atmosphere of the sun will expand to many times it's current size. It may even grow so large that it envelops the earth. It ... |
What are the science protesters protesting? | I was one of the 'science protesters' marching yesterday. I'm not going to discuss the pros/cons of science etc. in this comment because it's not answering OP's question; I'm just going to objectively explain why there was a protest. Our message was that we firmly believe that scientific input is critical and necessary... |
Why are motorcycles so poor on gas compared to cars? | Huh, never thought of it that way. Maybe it's an economics thing, where the manufacturers see 50mpg on a motorcycle as *enough* of a selling point, that it would take more money to invest in making them fuel efficient. Ultimately, maybe it's just a dollars and cents thing to make more money? |
What is the basic argument opposing net neutrality? Not from the corporations who stand to benefit, but from regular people. | In theory it would be used to put services like E-mail or others which are not as time crucial as streaming or online gaming on a lower rank. This way the Time Crucial applications gain speed which is highly appreciated, and the services that don't need to be fast are a bit slower, which no one really notices.The lure ... |
Why isn't there a viable alternative to Ticketmaster? | I have not delved into their finances except at a high level, but one thing I find curious is that they've lost money for the past 4 years. Their revenue continues to climb at an enviable pace but they still lose money. I did not look to see what factors are driving these losses but it's something to consider. If their... |
Why did NASA end the space shuttle program? Are they still doing other things? | I currently work for NASA as a spacecraft operator. We ended the manned shuttle program because it was costing way too much money to maintain the shuttle for every flight. The craft was costing in the hundreds of millions if not billions to re-launch every single time. It was decided that we just couldn't afford it. NA... |
Why cant the brain tell the diaphragm to stop hiccuping? | I can control my diaphragm to a certain extent. When I get the hiccups I only hiccup once or twice before getting it under control. The trick is to breathe in and out nice and slow and relaxing. Don't stop breathing in our out if you hiccup, just finish the in our out breath as if the hiccup did not happen. The key is ... |
How can a lawn survive a full winter covered by snow, but start dying and turn bright green from 2 days of being covered by a tarp (or something similar)? | Because it takes nature a full season to throw it's tarp over the grass. The grass has almost 3 months to prepare. It takes you 10 seconds to put the tarp down. That's not enough time for the grass to hold it's breath. |
Why does grass make people itchy? | When we sense something interacting with our body on any level, it registers. Lying in grass, for example, creates many separate interactions with your skin and a foreign living material. I believe human skin on skin doesn't register an alarm or itch of any sorts but interactions with plants, fibers, feathers, etc., an... |
Why are there seemingly no sound restrictions on motorcycles? | As a Harley rider I have ridden quiet bikes and loud bikes. While people do tend to notice you more when your bike is louder I also try to be respectful of the other people in my neighborhood. One aspect that nobody else has brought up yet is performance. A properly tuned bike with an open exhaust rinse better then a b... |
Why is food that is bad for us so inherently tasty? | Unfortunately at the time that modern humans were evolving, food sources were scarce. Thus it was more advantageous for an individual's survival and reproduction to eat food high in energy. Now that we have an abundance of food, we're experiencing what is called an evolutionary lag- that is, we haven't adapted to our c... |
Why does the *save* button of most computer programs is still a floppy disk? | It's an example of [skeumorphic design]. It's just the icon we know and so it has remained that way. |
What are current active research areas in mathematics? And what are their ELI5 explanations? | If you ask a Math question and don't know the answer, that's an open area for research. Heres one for you: what's the most efficient way to divvy up an N-dimensional sphere with smaller spheres, each of equal size |
