Why do humans not remember the first couple of years of their lives? | A baby's brain is unformed, it's just a great big general purpose learning machine. Those first few years are spent hardwiring the brain to deal with the situation it has found itself in, like how to move the body, how to respond to threats, what threats are, how to get attention and food, and so on. During all this th... |
The Golden Ratio and how it relates to the world around us and the Fibonacci Sequence | Others have explained how the golden ratio is derived from the fibonacci sequence, but as to why it's so often found in nature, well it's just really simple and effective programming. Imagine a plant that grows as a stem with leaves sprouting from it. A simple genetic program would be to grow a leaf every inch or so. U... |
Why is eBay such a monopoly, and why is there absolutely no competition even with thousands of people constantly complaining about eBay? | Complaints don't necessarily translate to customers leaving. They do have a huge head start, but the satisfaction level must be high enough that potential competitors aren't willing to risk capital for an uphill battle. It also likely means that the costs/difficulty of entry on such a large scale aren't worth the profi... |
How do steakhouse restaurants cook so many steaks at the same time to varying degrees of done-ness and get them all relatively correctly cooked for each customer? | Chef here. It's practice, practice, and practice. Running a busy grill is difficult and takes a lot of skill. However, that skill can be learned slowly. Line cooks usually rotate around and cross train during slow times. Once you've cooked a couple thousand steaks you just gain a feel for it.I worked at Texas Roadhouse... |
why are car colors so dull? | It took months to find a used car for my wife. We had the make and model picked out, but it couldn't be black, white, or grey/silver. We'd have taken red, blue, orange, yellow, etc. Finally found an orange one. Looks great next to my bright blue car. |
EU and the USA are pretty equal economically. Why do all USA major cities have massive skyscrapers while Europe has little to none. | In London there are planning laws limiting where very tall buildings can be built. It's to preserve the character and the view of the historic buildings that have made the character of London for hundreds of years. The best known is the Protected View of St Pauls Cathedral - one of the greatest pieces of architecture i... |
Why are stores often in need of coins? Where do all the coins being made even go if they are not in circulation? | How often do you use coins, especially pennies and nickels ? Chances are, not too often. Most people use bills or a debit card. If you pay for groceries with a $20 bill, and you get $1.34 back, then chances are you'll only use that quarter and the rest will end up in the couch cushions, or the car, or somewhere similar... |
What would happen if we *lowered* the minimum wage? | The difference is currently we take the many and leave the few behind. A lot of those who don't work do so willingly, or use state benefits to not NEED to work. People currently cannot survive on minimum wage, and lower it would only exacerbate that problem. I highly doubt companies will adjust prices significantly to ... |
How are tariffs bad for the economy? | Tariffs are taxing goods manufactured elsewhere and imported into your economy. The idea is to keep more money within your borders, which encourages more local manufacturing. We need manufacturing to be done *somewhere* so we can all have widgets to buy. If widget manufacturing is done in your local economy, then you c... |
How are there so many distinct British accents despite the relatively small size of the UK? | People in the UK often stay their whole lives in the same area where they were born - probably less so now than a generation or two ago but it's still fairly common. A few generations of isolation is plenty for even a small region to develop a distinct accent, especially with a fairly dense population. It's not limited... |
RE: Reporters / paparazzi who follow people around despite their clearly expressed wishes not to. Is that legal? | As loathesome as paparazzi can be, they are necessary. They are freedom of the press's worst case scenario. Any law that would restrict them for bothering a celebrity would also restrict legitimate journalists from investigating a corrupt politician. We don't want to make it any easier for them to hide. And the paparaz... |
Why do games on PC/phone crash sometimes but they almost never do that on a PS or an XBOX? | Because on a PC you have different drivers, different graphics card, different memory, and tons of other programs running in the background. A xbox is not going to run two games at once, and always has the same graphics card. So you test your game for that specific set up, and hammer out the bugs. If there happens to b... |
Is there such thing as healthy / unhealthy sperm? How to ensure the healthiest baby is born? | Ask your doctor about folic acid. > CDC urges women to take 400 mcg of folic acid every day, starting at least one month before getting pregnant, to help prevent major birth defects of the baby's brain and spine. _URL_0_ |
Why are there strict laws about using seatbelts in cars, but on buses and coaches etc that carry a lot more people seatbelts aren't used? | I was always told that it's because after a crash, a bus or similar vehicle can go up in flames so fast that any injured parties might not be able to escape in time due to being constrained by a seat belt. Again, this is hearsay and I've never heard any factual evidence to back it up, but it kind of made sense to me wh... |
Why do cameras need to focus? Why isn't everything equally crisp? | There is a way to get everything in focus at the same time - use a pinhole instead of a lens. The smaller the aperture, the closer it becomes to an ideal lens with an infinite depth of field - provided you can avoid diffraction effects at the edge - which appear worse as the hole gets smaller. You can even do this your... |
How can the Hubble Space Telescope keep its lens pointed in the same spot to take long exposure shots when it's orbiting the Earth every 97 minutes? | The objects it points at are so far away, that the rotation around the Earth is negligible. For instance, Andromeda is 1.49196325 × 10^19 miles away. The Hubble telescope is at an altitude of 347 miles, so as it moves around the Earth is moves roughly 8620 miles from one side of the orbit to another. Using trigonometry... |
Scott Walker's Seemingly Scandalous Policies | It's also worth noting that Walker deliberately created the budget shortfall that he used as an excuse to cut public unions' bargaining rights through tax cuts for businesses and by throwing money at other GOP sacred cows like a private health savings account program."Gov. Scott Walker believes a new law that gives gay... |
why are republicans against states legalizing recreational marijuana? | The Republican party at this point consists of three groups: the religious right , Rah Rah 'Murica and the libertarians . The last group is pro-legalization, the first two aren't. |
What gives gravity its energy? | Anything with mass bends space-time. Imagine a big plastic sheet tied out above the ground at the edges. This sheet is space time. Now imagine a heavy ball sitting in the middle of it and making everything sag towards it. If you put other smaller balls, they'll fall inwards because they are following the path of space-... |
Why hasn't Algae Fuel caught on yet? | If what you're saying is accurate, then it likely just boils down to money. If someone stands to lose money, then they will spend millions lobbying against it. |
Why is 0 divided by 0 undefined when any other number divided by its self equal to 1? | Looking at just division, 1 goes into 1 one time. 4 goes into 4 one time. 0 can go into 0 either one time, or a million times. So you can't define the answer |
Why do rainbows seem to have individual bands of color as opposed to a gradual color shift? | Not that I even know, but I'd suppose that the receptors in our eyes can perceive only so much of the wavelengths contained in the visible light spectrum. The rainbow portrays the colors at a certain intensity, while our eyes perceive it the way they will. As ELI5 as possible I guess: The rainbow does have a gradual co... |
How do people who end up in viral videos and/or memes suddenly become rich? Where does the money come from? (i.e. the “cash me outside” girl, and others) | It's basically the typical entrepreneur life.. exploit what got you famous, appearances in character, maybe a new or new characters, mobile apps, books, subscription based services .. a lot of these stars become serious musicians or actors as well even if they have no real talent. Really just comes down to how marketab... |
Why don't I have to enter my PIN for my debit card at McDonalds, but I do at other places? | I think it probably varies based on your card provider's particular rules. A lot of places run the debit cards as credit and most credit purchases under $25 don't require a signature, allowing you to quickly swipe, pay, and move on with your life. |
How are toilet paper rolls sterilized? | I run a small paper converting facility.That paper your convenience store breakfast sandwich or burrito is wrapped in isn't sterile either. It's clean but not sterile, just like the kitchen you prepare your food in. Cleanliness is important, sterility isn't. If it was, no one would survive the average camping trip.The ... |
Why is the discovery of America by Christopher Columbus so prominent in history? | Although there's evidence that other groups visited and lived in the Americas before Columbus, it makes more sense if you look at it this way: Columbus was establishing trade routes: he intended to go all the way around the world to meet up with people and lands that already had trade routes, but more complicated ones.... |
Why is the devil always depicted with goat like characteristics? | This is just an interpretation I have heard that makes sense to me. Jesus is a shepherd. Those who follow God are part of his flock, they are his sheep. Sheep are generally docile and loyal to their shepherd. Goats don't put up with that kind of shit, they pretty much try to do their own thing and constantly try to esc... |
Why is it so much more common to see people in Asian countries wearing masks during a virus outbreak as opposed to America? | From my best understanding, it's a bit taboo in America because if you're sick and contagious, you should be staying at home. |
How do companies who operate at a loss like Tesla and Netflix afford to pay their staff? | Also – addressing the question in a more literal sense – keep in mind that the negative balance already includes employee salaries. Employees are not paid out of a profit pool, profits are generally reinvested into the company or paid out in bonus's. Operating at a loss means that after paying all the bills the company... |
Why are brains in the vulnerable head rather than in the thorax with the other vital organs? | Follow up question. What about the neck ? It is actually thin and fragile. But contains the most important nerves, veins and the pipelines. Wouldn't it be more safe/efficient to have air and food intake directly on thorax ? |
Why do I not die sleeping in my bedroom with closed windows and doors? | Well for one thing, your room isn't perfectly sealed. There's probably air coming in from your window, through the walls, from vents in your attic, up from the basement, etc. Let's say your room is 16'x16' in size, and you have 10' ceilings. That's 2,560 cubic feet. We use about 19 cubic feet of oxygen per day, and if ... |
Why does the music industry have no problem with us ripping our CDs to our computers but the movie industry goes to every imaginable measure to stop us from doing the same with our DVDs? | The simple answer is because the music industry and movie industry are two separate sets of people, and the former has learned their lesson while the latter hasn't. The music industry *did* fight CD ripping at first, hard, for about a decade, but eventually they ran the numbers and figured out that they actually weren'... |
Why do people steal iphones if the FBI had such a difficult time unlocking the phone of the San Bernardino shooter? | I want to correct a few misconceptions people seem to have here. Yes, it is possible to factory reset an iPhone without the passcode to unlock it. HOWEVER, when the original owner sets up their iPhone they sign in with an iCloud account/Apple ID, and a feature known as Find My iPhone is generally enabled by default. Wh... |
Can mass abortion eradicate inherited genetic defects? | Eugenics can and does work, but that's not how Iceland got rid of Down's Syndrome. Eugenics is when the government stipulates that people with X and Y conditions are not allowed to breed and enforces it somehow. There's even worse versions - Nazi Germany outright killed the people it wanted to not breed and forced the ... |
Would I get better gas mileage driving a manual car in a lower gear (higher rpm) or higher gear (lower rpm) | Low rpm will give you better gas mileage. So once you get up to cursing speed, you should put the car in the higher gear you can for that given speed. This is also why you get better mileage if you skip gears when accelerating. For example, accelerating in 3ed gear to your decried speed and then shift directly to 5th. ... |
Why dont all movies go to the theatres? Why decides they'll go right to dvd? | Because they're bad, usually. Putting something in a theater requires movie theaters willing to gamble on your movie, and as theaters make such a tiny cut of the profits, they're very risk-averse. So often sequels that will have a rabid fanbase but no widespread support will go straight to video, where the margins are ... |
If it is easier to learn languages at an early age, why aren't foreign language lessons a part of American elementary schools? | Well because our economy doesn't have as much need for foreign language as other countries that are in more linguistically dense areas. |
Why Skype and Facetime have different video quality although they both use same camera? | actual ELI5: diff programs will limit ur camera differently. like 1 might make ur max qual at like a 5/10, and 2 might make max qual at like 7/10. possible reasons are saving money and etc. so even if u have the best cam in the world, it doesn't matter since the program limits it xdfp", 'Video is just information, like... |
Since being gay/lesbian is indeed not a choice, does that also mean that being a pedophile is also not a choice? | You are not supporting child sexual abuse by asking this. The answer is yes, this is most likely true. Recognizing pedophilia as an unfortunate condition could probably help children who are at risk. It isn't normalizing abusive behavior and might help increase social support in managing pedophilia. Though I couldn't b... |
Why do so many car commercials try to appeal to viewers emotionally rather than advertise features of the car? | A car is a way to express the type of person you want to be perceived as. They're selling a lifestyle not a car.All the technical information is available online if you want it. The hardest part is to actually get you interested in the car in the first place. Either to get you to actively desire the car, or at least ma... |
What is Putin's ideal end game? What is he trying to accomplish with Crimea? | * Goal #1: Keep the the Russian Black Sea Fleet. The Crimea is the location of a significant part of the Russian Navy, and the only access point that Russia has to the Black Sea and Mediterranean. Without it, Russian ships would have to set sail from the Arctic ocean and sail the long way around Europe. Because Russia ... |
Why can the POTUS repeatedly call media outlets, such as CNN and MSNBC, 'fake' without getting sued for slander? | Because it's not real news. It's commentary. There are no real news organizations anymore. They are all tied up with special interest and money. Journalists have done a terrible job at enforcing their ethics. |
Who does the Islamic State sell their oil to? | IS has trouble selling their oil. But it's probably sold to the same people who buy oil from everyone else. I assume the buyer believes that they are dealing with any other run of the mill . |
Internationally, why is Uber under scrutiny from cab unions? | Uber tries to skirt around the various laws that cities have in place to limit the number of taxis on the roads and driver certification/licensing that they require. This makes it easier for one to become an Uber driver, and it also impacts taxi drivers' ability to earn a living by adding competition. Taxi drivers are ... |
Why do many bars insist on playing music at deafening volumes? | I fucking hate it, but it makes sense, adds atmosphere, takes away social pressures to engage, people will dance more to loud music, less talking more drinking. It's weird thinking about how bars do this to make it less awkward for humans to meet each other. We're a very anxious and nervous species when the prospect of... |
If I raised a big cat solely by myself from birth, would it eventually want to kill me? | Probably. Most big cats are solitary animals, and even lions are territorial. Even if it wasn't actively trying to kill you, things like playing would be pretty dangerous with a 300 lbs big cat. |
How does our body determine what smells good and what does not? | It's got to be something chemical, primal, and instinctive. Like how our tastebuds as children, are wired to dislike vegetables, so as to stop us eating poisonous things off trees. |
What does it mean if a relative is "First Removed"? | Up until at least 21 I thought this meant the relative had done something wrong or bad so they were removed from the family x number of times. So a cousin once removed did something once but that aunt three times removed needs to get her shit together. I don't know why I thought that was logical for so long. |
When someone has hemorrhoids, what keeps fecal matter from entering the bloodstream, potentially causing infection? | The reason nothing untoward usually happens is at least four-fold: i) if white blood cell defenses are functioning normally , they eliminate any bacteria that have found their way into the blood ii) the amount of bacteria entering the bloodstream during things like bowel movements is relatively small and easily handled... |
Why will some printers suddenly come alive and make noise after being inactive for hours? | They're power napping. Please don't feed them after a certain hour and don't get them wet. |
How did people in the old west purify their water while on trips? | While on a trip, there was no need for them to purify water, especially in the American West. Natural water sources would have been completely free of most diseases as things like giardia would have spread later. In cities, that's a different story. With all those people came a ton of human shit and human shit water ha... |
How is it possible that Colorado doesn't get to vote. Serious question, not a troll attempt. | Look! You get to choose which side of the coin gets to be the president. You don't get to pick the coin. You don't get to pick who is heads or who is tails. |
Why Stephen Hawking is the long-lived person with ALS (Amyotrophic Lateral Sclerosis), what is the difference between Him and the others with same disease? | Some people now think that Lou Gehrig himself [perhaps did not have ALS]. Although as I understand it, an autopsy was never performed and no CNS tissue was collected, so we'll never know for certain.I am a RN. I had a patient with ALS for about 2 years. He was very advanced - he could not move anything other than a few... |
How is music made? | sustain", and "release." These are what cause a sound to have it's shape. In short, the attack is how long it takes the sound to go from silence to it's maximum , decay is how long it takes for it to go from that point to a rest. Sustain is when the sound still hovers around for a moment . Release is how long it takes ... |
How can one tell which source to trust for information, to avoid bias, e.g., say between a Texas School Book or Wikipedia, who should one trust? | you can't ever rely on a single source for information. I always check at least three different sources to make sure what I am reading is correct. |
Since long-term effects of vaping are unknown, how are people sure its safer than cigs? | If you vape extract from tobacco then I'm sure some risks stay in play. In a cigarette a number of compound are actually formed by burning. A lot of vape juices are made up of just water, flavor, and nicotine. Cigarettes form a lot of compounds that cause cancer. So far nicotine only serves for the buzz and is not asso... |
Why do schools past Elementary/Primary use a period system instead of having one teacher? | Complexity of what's being taught . I could probably teach the fundamental basics of almost any sport at a very beginner level. But would be utterly useless at teaching any of them at even a remotely competitive level. The deeper the material an concepts become, the more specialised and focused the teacher is required ... |
When picking up a prescription at a pharmacy and you have to wait 20-30 minutes for it to ready, what are they doing during that time? | based on a few friends who are pharmacists a lot of it is calling/being on hold with insurance co's. I'm sure understaffing/overworked is another aspect of it. |
Presidential pardoning powers. What is their extent and what was the reasoning behind originally granting US Presidents such powers? | It's a longstanding traditional power, for the chief executive to have authority to pardon/commute the convicted after they have been tried.The role of the Executive branch is to enforce the laws of the country. When a person is convicted by a court of law and sentenced to 30 years in prison, the incarceration of that ... |
I overheard my parents talking about a 504. I looked it up and it seems to be for people with learning disabilities. What exactly does it mean? | I had a 504 when I was in school that stated I could not be deducted points for penmanship and could not be punished for inattentiveness because of my severe ADD. The teachers would take time to make sure the whole class understood the subject which was a good hint for me to ask any questions I may have had. I felt It ... |
Why do my testicles have a very distinctive smell when they sweat? | It's a lot to do with the community of yeast and bacteria my friend. Keep 'em trimmed, keep 'em clean. |
If TV Shows make the bulk of their money through syndication, why not let all TV shows reach 100 episodes? | There's a limited amount of time on any given channel that would purchase rights to a syndicated show. They choose the ones that have proven track records of people watching them, or in rare cases, ones that are cult hits that might get a dedicated viewership, even if they weren't successful in their initial runs. For ... |
How is it that we can sometimes 'fall back' into a dream after we've already woken up? | It's because you became partly conscious then entered sleep while thinking about that dream while at the same time realizing you are awake. It's a form of lucid dreaming |
what will happen if you talk to your infant/toddler exclusiey like an adult (i.e. Not using baby-talk)? | Applied Linguistics MA candidate here. I personally don't like using very cutesy or sugarcoated language with young children, but using exaggerated intonation, emotive expressions, simple language, and lots of repetition/rhythm is actually really good for babies. It helps teach facial/emotional cues, conveys meaning , ... |
When people do colorations of old black and white pictures, does one shade of grey correspond to one color? | No. For this reason, it's difficult to tell what color a given thing is. You can just tell it's light or dark, and make some general assumptions. |
Why don't they put covers/grates on jet engines so birds don't fly in them | Any grating that would survive a 400 mile an hour collision with a bird would have to be a great grate. Great grates are heavy and restrict airflow leading to inefficiency. Birdstrikes don't happen often enough for the trade off to be benifital. Additionaly engines designed to havehave a good chance of surviving bird c... |
How do streets without traffic lights work? How do people not constantly get into wrecks? | When lights go out you treat it like a 4 way stop Edit: if other assholes don't know how to handle this round robin way of intersecting, you go when you feel it is safe, if that fails, when it doubt, throttle out my friend. |
Why does America have so many more police shootings than other first world countries? | Just look at the numbers man. It's 'african-americans'. Not black people. I would love to hear the opinions black people from other countries have of the 'african-americans' in the US. I mean Ferguson had to be just cringe - worthy for the race as a whole. |
Why does breath stink if you don't eat? | Eating causes the release of saliva. Lots. Saliva has anti-bacterial compounds. When you don't eat for hours and hours, bacteria may build up, causing bad breath.Your mouth is full of bacteria that poop everywhere. If you haven’t eaten in a while, you get too many bacteria and their poop starts to smell. |
How is it that Japan was once poor but is now economically prosperous, but regions like Africa and Latin America are perpetually poor? | I read a book on the exact same topic not too long ago, its called Global Economic History: A Very Short Introduction. Very interesting and inspiring read, I highly recommend it. _URL_0_ Basically, after the industrial revolution in England , other countries tried to catch up with a variety of strategy. The author summ... |
Why do we enjoy depressing/sad stories (movies, books, gamers, etc.)? | Personally, I enjoy watching or reading them bc they make me feel alive by making me feel the variety of emotions that I don't get to experience irl |
What is the need for an conductor in an orchestra as everyone knows what they have to play? | The most important thing a conductor does is provide a conception of the piece. The conductor asks for certain tempos, phrasings, dynamics, emphasis of accompanying voices, and even orchestral colors , all while being faithful to what he/she thinks the composer was looking for. By doing that, the conductor provides an ... |
What is the difference with Wines from Australia/Africa/France etc | Also, as a side note. You can't have champaigne if its not from Champaigne, France. |
Why have there been plenty of first person shooter games that portray Germans and Russians as antagonists, but there are no games where the Israelis are antagonists? | Because everyone is aware that being labeled an anti-Semite is a career-killer. It's unfair, but that's the world we live in. |
What is a Raspberry Pi and why is it so good at, whtever it does? | It's a small, cheap programmable computer. Hobbyists like them because they're cheap and simple. There's also a large fan community that publishes plans and designs. _URL_0_ |
How can cable send hundreds of HD channels at the same time but my internet is slow? | Because the bottleneck in bandwidth isn't between you and your cable company, but past them, where you're sharing the bandwidth with all of their other customers. With the TV signal, it comes into them via satellite so there's no upstream bottleneck and they can send it all to you. Also, despite what others have said, ... |
Instead of remembering dozens of complicated passwords, why don't we use just use fingerprint or retina scanners for everything like bank accounts, emails, online accounts etc? | Because they don't work well and are easy to spoof. In short, they are no better than what we're already doing.And when the dentist puts you to sleep and copys your fingerprints, What then ? |
The difference between light from the sun and light from a lamp, primarily when growing plants | They're all photons yes, but not all photons have the same energy. Sunlight has a specific distribution of energies, for example : it might have 10% 400nm light, 40% 500nm light, 30% 600nm light, and 20% 700nm light. In contrast, your lamp might have something completely different. It's still looks like white light bec... |
In the USA, why should I vote in a presidential election if the electoral college chooses the victor? | I think she more important one is why aren't electoral votes split as closely as possible to the popular vote in each state? It would be nice not to see many states ignored as forgone conclusions. |
If Ma Bell got broken apart for being a "regulated natural monopoly", why are cable companies allowed to function as monopolies? | one simple answer: there's a LOT more money being used to buy off government departments and governors, congressmen, representatives, lobbyists, and other absolute scum to leech even more money out of americans.Actually Comcast has already admitted to collusion with time warner by how they both agree not to compete in ... |
Why do mental health professionals consider it okay to take mood altering prescription medications, but not okay to smoke weed to alleviate depression and anxiety? | AFAIK the answer is in the immunity cycle. Antidepressants are sometimes called SSRIs, or Seratonin Re-uptake Inhibitors. Basically, their function is to prevent your brain from dismantling seratonin after it is used. Your brain will not produce seratonin if there is too much, but levels will still naturally dip and yo... |
From an evolutionary stance, why are humans bereft of basic defenses:claws, canines, thick hide..And instead runs with diverse body types, no fur, and exposed vital organs? | Since humanity knew fire and tools, we had pretty much no predators that were a real threat to us anymore. Also humans always were living in groups and worked together, which made them superior to single hunters like bears. We also never had to rely on claws or superior strength or something for hunting. The human hunt... |
Why do NFL teams have a draft and not just buy whatever players like they want like in soccer? | It allows for a more even playing field where any team can get some world class players and potentially do well. In European soccer any team with large amounts of money can just buy top quality talent and artificially become a powerhouse in a very short amount of time and also because this leads to the top players only... |
Why is encryption illegal in certain countries? | encryption" and "export" meant with software this law never anticipated, a lot of software makers were afraid their products might not be legal, and turned to disclaimers like this. Other, more restrictive country just banned strong encryption altogether. |
Why does my son's stutter go away when he talks in an accent? | I think it is because mimicking an accent uses different parts of your brain than simply speaking habitually. Whatever is hampering the signal when speaking isn't necessarily in the way when using other modes of vocalization. Apparently singing and speaking foreign languages have the same effect. |
What is proper gym etiquette? | You asked for gym etiquette, but workout etiquette when doing cardio might also be important to you. If money is tight and you can't afford a gym membership, then running, biking, or staying fit outside is always an option. I found its a good way to do your own thing and ease yourself into a full-time routine later at ... |
Why aren't pyramid schemes sustainable? Why are they illegal? | Besides the obvious reason that you will run out of people, I think it's also stupid to believe that a proper job will require you to pay to be in it. The companies that run these schemes obviously do it for profit, so they obviously aren't going to return more than the users get them, so many people end up losing what... |
Why do running shoes, almost as a rule, always use a stunningly ugly colour scheme? | Running shoes come in many colors and designs. The brands that make running shoes make a variety of models every year. Every model has their own color schemes that tend to change year to year. There are two reasons that you would find ugly running shoes. The first is that the shoes that you see are the ugliest of color... |
Why don't ISIS and Al-Qaeda like each other? | The Bloods and the Crips are basically the same they are just another gang. it's not about similar beliefs, it's about control of land, hidden behind religion. |
Why don't we develop a new international language? | We did, but it turned out that people preferred speaking their native languages and learning languages that were already established somewhere else. It's basically game theory. Everyone choosing to learn Esperanto would be an optimal solution for everyone. But learning Esperanto when nobody else does is a losing propos... |
If atmospheric pressure exerts 1 ton of pressure on me, why can't I feel it? | That's not how pressure works in fluids, including air. You're thinking about it as a force that only pushes down, as if it were coming from a solid. But fluids exert equal pressure in every direction, *including up*. Gasses in particular expand to fill all available volume, and that involves exerting pressure in all d... |
Why do movies and TV shows usually use unique OS's on computers as opposed to common operating systems like Windows? | Simply put, there's no good reason to use a real OS if they're not being paid to. When the cops are searching their database for a fingerprint match on a TV show there's no special program being run. It's just a graphic that's added in post production that was designed to clearly show the viewer that the computer is se... |
Why haven't we developed cars that run on hydrogen yet? | Because it's not that simple. It takes energy to get energy and we still need to work out a lot of the kinks to make it viable in mass production. |
Why are thorium reactors better and why are we not funding it? | One of the issues that hasn't been brought up so far is that molten flouride salts can be incredibly corrosive and eat away a lot of existing containment materials. There are new alloys that they think can deal with this problem, but that's not a sure thing yet. |
Why does liquid rock and metal glow? Why doesn't water behave the same way? | If liquid water was 500 degrees Fahrenheit or Celsius, yeah, it would glow. That's just giving off heat. |
Why are all doctor's handwriting so messy, and how do pharmacists decipher what the prescriptions say? | The reason for me is that I'm often tired of writing the same thing over and over again!
