why "there is no gene for race" | Race is a social construct, not a biological one. You and a member of a different race may possess most of the same genes, and you and another member of your same race may possess mostly different genes. There isn't a gene that says asian when you are being born. There are a clump of genes that, when put together, make... |
Why is it that after a while a battery charges faster and is empty faster, and how to prevent this? | It actually isn't charging fully. I have yet to get a solid explanation of why this is, but it has to do with either some of the battery chemicals not reacting, or the percentage showing on your phone incorrectly. Either way, the fix is to drain the battery to zero - run that sucker until the phone shuts itself off - a... |
why does it cost more to make your own trail mix ? | Because you're buying individually wrapped convenience-size components? Trail mix costs between $7 and $10 per pound, and typically uses very cheap components for 50% of the weight . At nearly any grocery store with bulk bins , you can make better trailmix cheaper.It has a lot to do with the quality of ingredients, I w... |
What determines if an earthquake is an aftershock or an entirely separate event? | I answered this question yesterday [here] on the r/AskScience subreddit. TL;DR It has to do with the epicenter of the aftershock within a specific time frame. Specifically, is the epicenter along the same fault line as the original earthquake, and do they happen within a short enough time span that they are therefore p... |
why can I buy a 8.9" tablet with 2560x1600 res but I cannot but a 20" or 24" monitor for a couple hundred dollars with the same res? | Because you hold the tablet at 5 inches from your face while monitors are typically a few feet from your face. That's why TV resolutions are only 1080p still; at a certain viewing distance the dpi doesn't matter because you won't be able to see individual pixels anyway. Not saying I wouldn't like the resolutions to go ... |
why did animals stop evolving to the size of dinosaurs? | To add to what toxic_badger said, oxygen levels are important, but some of it also has to do with land mass size. Back when all the landmasses were more connected, animals had larger areas of land to work with . This means access to more food sources, so larger animals didn't as easily die of starvation. This can be se... |
Why does time seem to pass by so much faster as you get older? | I think of it like a long commute to work. The first few months that commute seems to pass so slowly however the more you do it, some days the commute seems to just fly by. The distance was the same however since you have been on it so many times you stop paying so much attention to everything therefore it doesn't feel... |
How come the Constitution of the US is relevant in modern cases even though it was created on 1787? | The Constitution and especially the Bill of Rights outline the basic rules on how the government should be run. More than rules, though, they lay out a basic philosophy on what's most important . In cases that deal with Constitutional issues, the courts are trying to determine if the philosophy of the Constitution is b... |
How come passengers on buses or limos don't have to wear seat belts but the every day car does? | When I was growing up back seat passengers were not required by law to wear a seat belt. I don't know if that has ever changed but it could explain why bus, cab, and limo passengers aren't required either. |
How does the Space Station not run out of oxygen? | In the movie Apollo 13 you may recall that they have problems with C02 in the air and need to use all sorts of random junk to build a make-shift C02 scrubber. Maintaining the ratio of C02 to 02 in the air in a closed system isn't anything new. |
How is paid leave a legitimate punishment for police officers caught breaking the law? | Not a police officer, but firefighter in one of the bigger US cities and the PD and FD share policies for Internal Affairs. Technically, suspended w pay means you're supposed to be at home and must be able to be contacted between the regular working hours. IA officers are supposed to check up on the officers to make su... |
Why is it so much easier to kill a fly with an object rather than our hand? | On an only slightly related note, you can catch a fly with your bare hands. The trick is in the approach. When the fly has landed on a relatively flat surface SLOWLY approach it. You want to get your hand to within about 5-10 cm of the fly. In order to avoid spooking the fly you can move no faster than about 1 cm/s, sl... |
Why did Honda's hydrogen powered car not take off? | Correct me if I'm wrong but I think it would be due to the fact that hydrogen is one of the most volatile elements in the world. Enclosing it in a small container moving at high speeds would be extremely dangerous. |
Why doesn't Google push for nationwide fiber? | Its takes a massive amount of time and an insane amount of money. This is kind of like if a company decided they were going to singlehandedly rewire the entire US's telephone lines. Think about the scope and cost of that kind of project. |
Why do hikers carry De-Hydrated food when they still have to carry their own water anyway? | If you are a serious hiker, you will have some sort of water purification on you , which means you can re-stock your water, as you can plan your walk to go past a river. Having the food dehydrated means you can carry a lot more as the food weighs less and takes up less space in the bag. If you are only hiking for the d... |
Why are popular iPhone/Android apps valued so highly when they are often free without built-in advertising? | It's all about marketing. Your attention is what is valuable. Even if it doesn't get money from the users, some company is willing to pay millions of dollars just to have access and exposure to X million people. The trick is doing it subtly. Most of us try to tune out ads that we know are ads. Reddit is actually really... |
Why isn't the ratio between turning the steering wheel and the actual wheels in a car 1:1? | Most driving isn't massively sharp turns. Most are subtle turns that require precision. Go-carts steering is like you describe and it's hard to make delicate maneuvers like stay in a lane. It's like if you set the mouse sensitivity to max on your computer. The pointer flies all over. Also, before power steering you nee... |
How does peasant food become popular? | I read somewhere that the lobster served to poor people back then was just ground up and served as mush. It wasn't prepared as a delicacy. I don't have information about why it took so long for people to learn how to cook it correctly.Nova Scotian here, can confirm lobsters used to be so plentiful that they were poor f... |
if we put a $15 minimum wage into law, won't every business inflate their prices in response, eventually returning the minimum wage to its previous "value"? | I actually came here to ask a question about the $15 minimum wage deal. Currently, I make substantially more than the federal minimum wage, but not really enough to be considered wealthy. If I break down my salary/commission to hourly, it comes out to about 24-25 dollars an hour. If the minimum wage is increased, infla... |
Why do we sometimes hear a very high frequency sound for a few seconds out of nowhere? | I think it's most likely that the noise you're hearing is electronic feedback through the microphones that the FBI have implanted in the drywall of your house. |
Why was hitting 400km/h so hard to achieve in this age of technology? | The faster you go, the higher the resistance from wind, from internal friction , and from external friction with the ground. You need more and more power to overcome it. Notice how much easier it is to make an airplane go this fast -- that's your clue that the problem is with having wheels that move along the ground. |
Is there any evidence for pedophilia being something that a person is born with and is therefore something that they are susceptible to throughout there life? | I don't see how it's not thought of as a socially inappropriate fetish as opposed to a disorder. If you look at it objectively that's what it is |
My dog just barked at a doorbell on TV, but my dog has never lived in a house with a doorbell. How can she recognize what that noise is? | My dog does the exact same thing. Even when the door bell in the tv show sounds nothing like ours. And there aren't dogs in the show. It's super interesting. |
Why are Ethernet ports so bulky? Can/will they be improved and/or reduced in size in the future? | When the connector was designed and standardized, computers were much bigger. It was considered a small connector at the time. Yes, it could be replaced by a USB-C style connector -- but then you'd need an adapter for all those old cables. |
Why do old light gun video game accessories (like the NES Zapper) not work on modern TVs? | Timing. When you pull the trigger on the NES Zapper, the game flashes a black screen, then white squares where the ducks were. The gun is just a photo-sensor and sends the data back to the NES. So, if the game senses a black-then-white pattern at *exactly* the right moment, then the duck was shot. The problem is while ... |
What purposes does pubic hair serve? | Remember our body design is supposed to be for nude, in the midst of nature. It prevents dirt, germs, and bugs from getting into the holes. Also providing minute warmth. That's basically it. Same with foreskin/labia skin. |
Why are credit bureaus allowed to charge us to look at our own profile? Who are these people anyways? They aren't a government agency, so how did they come to exist? | The real root of the problem here is that so man people are able to gather data about you. You make a credit card payment to your bank - and Experian are able to get details of that. Why? Fuck Experian, they're a bunch of scamming leaches. Details of that transaction should ideally remain private between you and your b... |
Why after 30+ years of life do I still randomly choke on my own spit at random? | This is so bizarre, I can't believe it. I just turned 60, and in a blinding display of synchronicity, *just two days ago* this happened to me for the first time in my life. I was seriously in distress! I coughed my throat raw… and then I see it on Reddit. Weird. |
why can't California just pump water from other states (like the ones that are flooding now) the same way they pump oil? | Because doing so would be expensive and complicated. There have been proposals build a [pipeline from the great lakes]. In regards to the flooding, you'd have to build a pipeline to an area before it floods, but that pipeline would be unused and costing money until the flood happened, and then be unused and costing mon... |
Why are viruses not considered living? | Viruses can't reproduce and have no metabolism. Think of them like a program where the cell is a computer. |
Why can most people only write with one hand? | It's an experience and practice issue. Writing with both hands is not a common requirement in life so most people only practice and write with one hand. Your other hand is awkward purely because you have no practice. If you took someone writing with their off hand and someone learning to write for the first time they w... |
If plants grow berries to spread their seed via animals who eat them, why are some of them poisonous? | Plants do not care if they a poisonous or not. And they do not care if they spread seed via animals or some other way. They just grow as their genes tell them to. Sometimes genes become randomly changed and tell plants to be different. If for example, the plant will stop growing seeds - then it stops reproducing and wo... |
Why do movies portraying ancient civilizations (i.e the movie 300) have actors speak with English accents? | In many cases, American films utilize foreign actors to make the characters seem like they're from a different time or place. Star Wars films did this to differentiate the rebellion from the empire. Ben Kenobi was portrayed by a Brit to link the rebellion to the early days before the empire. It's not supposed to be as ... |
Why do stairs always exhaust me so easily if I’m in pretty good shape? | Climbing stairs is much more taxing than most people realize. Not only do you need exceptional cardio vascular endurance, but also great muscle strength and endurance in your legs. This is why mountain climbing is so unique and grueling. As an example, a climber who summits Mt. Rainier via the standard DC route will ga... |
Why does it seem you either believe in creationism or evolution? | As far as I am aware, there are no competing hypotheses to the origin of species. Either they were created as they are now, or they became this way naturally over time. I can't see how one could deny both theories. |
Why do toddlers have an instinct to throw themselves on the ground then kick and cry/scream when they don't get what they want? Why not just stand/sit and cry? | I've seen an adult woman do it before. I have no idea why. Maybe the flooding of such a strong emotional response makes your body behave oddly, like it literally doesn't know what to do with itself. Crying just isn't enough to release the energy.My daughter did this at age two. In the middle of one, I took her into the... |
"Jesus died for our sins" - what exactly does this mean? | Let's God is the judge at your local court house and Jesus a public defender. You get a ticket for speeding and have to stand before God. You're guilty, you know it, God knows it. God says your speeding potentially endangers innocent bystanders and it's not fair to people who follow the rules to have to put up your rec... |
Why are there so many types of screws? (Phillips, flathead, Allen, etc.) Why isn’t there a single, standardized type of fastener? | Different screws and heads are for different materials and torque pounds. Phillips heads are a + so that when overtorqued you strip the head vs snap the screw I'm half. Look at an Alan head screw , it'll.tighyen forever u til it snaps. Etc etc for every other screw |
Why you should put pasta into boiling water and not throw it into cold and boil them together? | mostly the issue is sticking or burning, at a rolling boil pasta will self agitate. If you keep stirring occasionally while waiting to achieve a boil things will be fine. if you don't do that then you will end up with noodles sticking together or tot he pan and keep them off the bottom where they could burn. |
How is motorcycle insurance significantly cheaper than car insurance? You'd think it would be the other way around. | Umm, what? Motorcycle insurance where I live is about $4,000/yr, in comparison to about $1,100/yr for a car. Basically, our insurer thinks you will die if you get a bike. It's like this in other provinces too, I've never heard of it the other way around. |
Why do many countries use U.S currency, how do they get it, and what affect does this have on the value of the U.S dollar? | **Why do countries use US Currency** A good case study for this is [Zimbabwe] which officially demonetized after hyperinflation rendered their currency worthless. The US Dollar is much more stable, so switching to it removes a lot of the problems with hyperinflation. It can create other problems. For example, Greece's ... |
If mouthwash kills germs, then why don't we spit it back into the bottle? | who says you can't? As long as you do it to your own bottle, it's ok. Just don't do it to someone else's bottle. |
How does Starbucks coffee always taste the same, despite the beans coming from presumably many different farms, weather patterns, vintages, etc.? | Well, drip coffee generally taste's pretty similar, the filters themselves absorb most of the oils the give each coffee their distinctive flavor. If your local starbucks has a [Clover] machine, I highly suggest you try out the variety of [reserve] beans they have, each one has a pretty different, some good some bad, ta... |
Why do wind turbines spin much faster when there is no out wind. Also, I see them barely moving when it's quite windy out. | Just because there isn't any wind on the ground doesn't mean there isn't any up at the turbines' level. Wind tends to be more consistent the higher up you go. |
why does diabetes cause people to lose their feet? | One of the side effects of diabetes is poor circulation, especially in the lower extremities. The longer this goes unchecked, the worse it will become. Gangrene can set in quickly, and since it is usually not painful, goes unnoticed until it is too late. That's why frequent checks are so important, and exercise is also... |
Just say.. We had the technology to lasso Mars and bring it to same position Earth is to the sun, Would Mars eventually be habitable like Earth is today? | I always thought about this. If we were able to master nuclear fusion, we could build a mini sun to orbit around mars feeding it energy. Then we would need to give Mars a magnetosphere. Our magnetosphere comes from our molten iron core. I doubt this could be replicated. Since mars is less dense, and not volcanically ac... |
where do the calories go when your body burns them | Waste heat. Matter and energy are the same thing, so you're literally changing physical things into heat and dissipating that heat out into the air around you. |
Why does taking a picture of something on a screen (laptops, cell phones, TV, etc.) cause bad pictures? | As elaboration on what others have said, [here] is a picture, taken on a phone with a sensor that scans from top to bottom. The green light is from a laser source; it pulses for either micro or milliseconds; I didn't calibrate so not totally sure. Either way, as you can see, the laser was on when capture started, but t... |
Why hasn't North Korea collapsed yet, like the USSR? How do they make money? | Name your favorite totalitarian dictator and his statue was probably manufactured in North Korea. Don't think you can sustain much of an economy with this industry, but NK probably doesn't have much of an economy to begin with. _URL_3_ |
Why are there free refills for soft drinks in the US? | Syrup is not pennies for most restaurants. Even if someone like McDonald's can get the syrup for half of my example below, it's far from pennies. 5 gallons of syrup at our local Coca Cola bottling plant is $81.98. 5 gallons of syrup makes 237 - 16 ounce servings at a 5:1 water to syrup ratio. That is $0.346 for 16 ounc... |
If a postal worker sorting mail sees mail addressed to himself, can he take it, or does it legally have to be delivered to his mailbox? | Used to get a manager to put his signature on envelope, just to make sure you were not stealing someone's mail |
Both sides of the Dorner scenario. | I wonder what it's like to be an LAPD LEO, on the beat Are these LEO's just constantly in a state of alert? Stressed out to the point that the lines just start to run together? I mean, dealing with crack heads, thieves, murderers, rapists, abusers etc. every day at work, doesn't that just make you go mad at some point?... |
Why is it so hard to correctly plug in usb devices the first time? | Because you've got a 1 in 2 chance of being correct and the USB gods tip that to more like 1 in 50 |
If a girl's body is "ready" to give birth once they start getting their period, why is it considered dangerous for people to do so at a young age? | Sex itself is not dangerous after puberty, physically. But it can have severe psychological impact if you aren't ready. Just think about how having sex affects you and who you're with even as an adult.. then think about applying that to the mind of a very young teenager. That rarely goes well. |
How does animal/plant create some of the most potent poison out of nothing? | Its the complexity of the recipe that's stored in its DNA through million of years of evolutionary fine tuning |
Why are there so many people descended from Ireland and Italy? | That's your first person view, based on where you live. There are far more Indians and Chinese. |
Is an employer legally entitled to repayment if they mistakenly overpay an employee | Here in Australia, an employer can only legally recover overpayments from their employees / former employees from the previous 6 years. Any overpayments made that are older than 6 years cannot be recovered.Edit: I have absolutely no idea why I've been downvoted. My partner is an accountant and deals a lot with the lega... |
Why at there laws during war? | They're there because many people have realized that even when we get down to such barbarity as lobbing bombs at one another there should still be standards about doing it without being entirely and unnecessarily evilly. Shooting white phosphorous into civilian buildings, for example, is just completely unnecessary and... |
If food gives you energy, why does eating a big meal make you tired? Shouldn't you go run a marathon or something? | The calories and nutrients aren't instantly absorbed by your body. It needs time to digest. The sluggish feeling you get, which happens when you eat too much, is because a lot of your blood is being drawn to your stomach to add in the digestion.It takes energy to extract the energy from food. You feel depleted over the... |
Why did beer taste awful as a child but taste so good as an adult? | Because most of the beers that were in my house were shit. This is why when people, mostly women, tell me that they don't like beer, I always tell them that there are way too many beers for them to be put into the same category. |
Why do a lot of people do not consider pirating online material bad? | For me, I pirate content I wouldn't purchase in the first place. I know that it is wrong, but, if I torrent a movie that I would never pay to watch, then they company isn't losing money, they're just not gaining any. It is stealing either way though. |
Why did humans evolve to have less facial/body hair? | Sorry, this isn't an ELI5 answer, but I was thinking about this the other day. What if we evolved less body hair to help with communication? Think about how the subtlest changes of expression on the face can be picked up. If a neutral mouth gets even a hint of a smile, you will notice it. If the eyebrows droop in even ... |
Why do we sometimes get an unstoppable laughing fit when we hear/see something that wouldn't be funny enough to make us laugh on a different day in the same situation? | I start laughing when I'm afraid or in a lot of pain, why is that?", 'In drama and film we know it as a phenomenon that requires "comedy relief". People have the desire to laugh, and when there isn't a good opportunity for laughter, it will come when least expected or inappropriate. Older dramatic films unintentionally... |
Why can large files like video games be stored and used on a single disc while presumably much smaller things like seasons of shows take multiple discs | Because shows aren't small. A good quality video can easily push over a gig per hour of play, plus the menus and extras and commentary and all the other useless shit, those discs fill up fast. |
What's the deal with Intel 6-core and AMD 8-core CPUs? | Check out a benchmarking site like _URL_3_ and compare them in performance. The $100 AMD just doesn't compare to the $600 Intel, but it is probably much better than Intel's $100 CPU. Also keep in mind with today's CPUs you usually have a GPU built in, and generally the AMD one is better. |
How does the SAT put those from lower socioeconomic classes at an disadvantage. | This is a leading question. I believe the SAT is flawed, but I don't think this translates into a meaningful disadvantage for less fortunate children. Here is a good example of a way the SAT system could be flawed, that may support it being unfair: To take the SAT generally costs around $50. Kids generally don't have $... |
Why does congress vote in a way that everyone knows what each person voted for instead of in some kind of blind ballot. | People want culpability. The same mechanic which would allow a lawmaker to dodge lobbyists by not having to record their vote would allow lawmakers to tell constituents that they're a gun-loving, bible-thumping, tax-hating Super Republican and then go vote to build statues to Marx. It would be untenable. As an aside, l... |
Why is the AK-47 such a popular weapon | It's simple and inexpensive to operate, build, repair, and maintain, being originally intended for uneducated conscripts. It fires the cheapest and one of the most effective anti-personnel rimless rifle cartridges; has loose tolerances so parts can be interchanged, substituted and even hand-made if necessary; has adequ... |
Why are those cows mesmerized by the girl playing the accordion? | Cows are interested in anything new, I remember a story by a mate who was playing with a gun as a kid when he wasn't allowed to, the farmer came along and he hid it in the hedge and kept walking, but he got busted because the cows went to investigate and sniff the strange new object and the farmer noticed.Cows will wat... |
Green Laser pointers (modding and legality) | First, green laser pointers aren't necessarily more powerful than red ones. The operate at a frequency the human eye is more sensitive to, so they appear brighter. In the US, a laser can't be sold as a laser point unless its output is less than 5 mA. Larger lasers, up to 750 mA, are commercially available to the genera... |
Why do some people pay $2,000 or more a month in rent rather than just buy a property? | Because in places where $2000/month rents are common, mortgages are significantly more than $2000/month. On top of the reasons others have mentioned renting is still sometimes the better financial choice. If you treat it just as an investment, you need to look at the price difference between a rental property and buyin... |
Why people think crystals have powers, healing ability, or other capabilities and why? Is there any scientific evidence? | Crystals look magical, because they're mysterious and shiny.There is no evidence to support any healing factors in them, though. I'm sorry, I really don't know what else to write. |
How come produce isn't allowed on airplanes but other food like snacks are allowed? I see no harm in bringing an apple or banana with you back home from another country. | Just to clarify, produce absolutely is allowed on planes. My wife often brings produce with her as a snack when flying from state to state. What isn't allowed is transfer of produce _between countries_. As others have said, this is because produce is capable of transferring agricultural diseases. |
What happens if you buy a car that was stolen? Who is responsible? Do you get your money back? | This happens frequently. If you buy a stolen car, you're at fault. You may not be charged for stealing the car if you can provide some proof you purchased it, but the car goes back to the owner. This is why a lot of pawn shops don't accept things like golf clubs, because they're frequently stolen and if they have somet... |
What goes through an autistic person's mind when they are on a higher spectrum of autism? | I have a friend who is mildly autistic and synesthesic . He wrote a scifi/fantasy book a couple of years ago where the main protagonist was a creature who perceived the world the way he does. It's not your usual story/plot progression and gets hard to follow from time to time, but it was a very interesting look into wh... |
Do people from developing countries have a stronger digestive system than others due exposure to poorer hygiene standards/ random street food? Or are we all the same? | The nutritionist is right, eventually your body's response to pathogens and new organisms will be softened, and will begin accommodating them in a less .shitty way. People experience these things differently, however. A little advice from a chef who has traveled, though. Produce, out of it's husk, peel, bran, whatever ... |
Why does every computer I own need to have the clock reset every month or so when I'm almost always online? What do cell phones know about keeping time that laptops don't? | Well, left to their own devices, any computer clock will drift a bit, laptops moreso than desktops. Most automatically set themselves though The reason cell phones keep better time is because they're usually set to take time updates from the network by default and do so much more often. |
What the hell happened to MTV? | Id say youtube and the internet in general. MTV used to of course be about music but when you can go listen to download and watch anything you want at anytime and even anywhere with phones these days it makes it kind of hard to have a channel focused purely around music. People aren't gonna tune in anymore just to see ... |
How does a stick shift save gas? | Mechanic here. 20 or 30 years ago this was absolutely true. Most transmissions were only 3 speeds, and torque converters had constant slippage which raises engine RPM and creates heat. They were crudely controlled and had significant slip between gears. Manuals removed all of that. The clutch only slipped when the driv... |
Depression. How can someone not be able to get up and do things? | GREAT book recommendation for you [Stumbling On Happiness]. Explains this very thing and is a VERY good read. Essentially Our minds are wired to project what's happening today on to tomorrow, and so on. When your today is sad and depressing, you automatically want to think tomorrow will be as well. It's a thought proce... |
Why are mice used to test drugs on? | To kind of add to this question. How do we know drugs that produce negative results on mice won't produce positive results for humans? |
why is a large part of our nightsky not completely light, if there are BILLIONS of stars in our galaxy | Billions of stars sounds like a lot but then you have to consider how far apart they've spread. Like, imagine the night sky is a grid of pixels, 1,000,000,000 pixels wide and tall. Sirius, one of the closest stars to Earth, would be about 10 pixels tall and wide on that grid. That's our closest neighbour. Billions of s... |
Are car salesmen really all that necessary these days? | You can look at a car on a computer screen all you want, but there's still value in being able to see a car in person, get in, and take a test drive. However, the real reason car dealerships are still mandatory in a lot of states is because it creates jobs for car salesmen, and generates tax revenue. |
Why do bathroom stalls have the bare minimum amount of privacy? | Besides making it easier to clean them, there's a desire to limit just how private they are. Some people will use public bathroom stalls to do things other than what they are intended for if they are *too* private ", 'Protip- 99% of the time you have a question in the form "Why is there less of x instead of more?", the... |
Why do hunters wear camouflage, if they're going to cover it with a blaze orange vest & hat? | In most places, you don't need to wear blaze orange for the species where camo really matters , or you only have to wear it while hiking in/out, not when you're in a blind or tree stand. For animals like deer, smell and movement are more important anyway, but the hunter may use their gear from other animal seasons. Ano... |
Does RPM need to increase to maintain speed on a hill if you didn't change gears? | There are two other factors to consider besides the rotational speed or RPM, torque and power.\r\r\rPower is dependent on how much gas you burn, it is also equal to the output RPM times the output torque. In some made up units, say you have a power of 4, a torque of 2, and a RPM of 2 on flat ground. You now go up a hil... |
Why is Japan mocked for its' prevalence in suicide, when there are 9 countries that have higher rates? | I remember doing a report on suicide rates years ago and Japan was a bit higher on the list at that time. Also, if you take a look at this [chart] Japan's suicide's rates are a lot higher than other wealthy countries. What I wanna know though, is what the hell's going on with the men in Greenland??", 'Probably because ... |
The misconception that we only use 10% of our brain | We don't use 10% of our brain. The back of the brain is used for vision, the front makes your personality, the bottom bit helps you balance and move, part of the side is used to talk and listen. We use all the brain. |
How come the Sun is sufficient enough to light the Earth and the Moon, and yet space is all black? | The light intensity responds to an inverse square law, we are relatively close to the Sun so we get enough light but the space is huge, so huge it actually becomes almost black. Your question is a really good one, it's similar to the Olbers Paradox |
Why do fan and propeller blades often have different shapes and angles of attack? Why does the number of blades vary, shouldn't there be an optimal design? | Well, I know that on AC condensers/heat pumps, the design of the fan blades can affect system performance. Different blade pitches and counts can have adverse affects on fan motor amperage by increasing or decreasing air resistance, refrigerant liquid pressure by changing air flow across the coil, and compressor ampera... |
How did people with poor eyesight live before glasses were invented? | This is a major part of a theory I love regarding why Chinese tech dropped behind Europe. Ok so bear with me my grammar is terrible and I haven't had much sleep, So back in the day the Chinese were clearly far ahead of the West. One invention in particular they wouldn't share with us was, China that is the material the... |
In retrospect, why was germany left largely unscathed from the 2008/2009 financial crisis? | It wasn't it did suffer some economic hardships from it. But it is not as tied to the US so it was able to weather the disturbances better.One factor is the concept of "Kurzarbeit" - a government program which, in an economic downturn, allows companies to reduce employees\' working hours while the government pays the e... |
why are rape cases so hard to prosecute? | Rape is hard to prosecute for two reasons: 1. It happens in a private place. You can't pull up the surveillance video or talk to witnesses like you could for other crimes. 2. The accused will often claim that the act was consensual. This is very difficult to prove or disprove, because you are trying to prove what was i... |
Why humans are the only species that has to drink "clean water" and animals can drink seemingly any water they want without any problems | A lot of it has to do with our immune system being used to clean water causing toxins in water to do more damage because they're not recognized. |
Why Has Evolution Not Taken Care of the Need for Glasses and How Did our Early Ancestors Survive? | Evolution isn't about being stronger or faster, it's about having more offspring. For the bulk of human history we were hunter/gatherers. Men went out and hunted, many died in the hunt. But Ooog can't see shit. He's not much use on the hunt. Leave him back at the cave with the women. Who fosters more offspring? Ikat wh... |
If I need to be rescued (from forest, sea, war, etc), who pays for it? | This varies depending on where you are. Some parts of the world you'll probably be left on your own for some while, even if you took out insurance before you set out. When governments issue passports they sometimes provide guidance on what to expect, along with recommendations to check for updates and take suitable pre... |
Why in English "T" and "D" sometimes sound like a Japanese/Spanish "R"? | Something to note is that this occurs whenever we have 'T' or 'D' between vowels and the first vowel is stressed. For example, 'wáterbútterládder,' and not 'boutíquevoluntéergrotésque'.Both sounds are made by tapping the tongue against the alveolar ridge, the boundary between gums and palate. The difference between a t... |

Why are people upset over Facebook Messenger | Don't know about others but my reasoning is that Facebook has a bad history of changing its privacy agreements and hiding them. So what is an approval for an innocent reason can be changed to something beyond what I agreed to . Bottom line, I don't trust facebook", 'Because it is Facebook! *Dun-dun-dunnnn*!!!! Seriousl... |
Why does the UK have so many accents despite being a relatively small island country? | Same thing in Austria - it is a very small country, but there are countless different dialects. It is entirely possible that two towns a mere 20 kilometres apart speak a wholly different dialect. It probably has something to do with people rarely leaving their hometowns back in time. It is comparable to spending a lot ... |
