if you can't compress in liquid why is it the deeper you go in the ocean the more atmospheric pressure you experience. | Imagine a cylinder of metal. The taller you make it, the more it weighs. Therefore, the more pressure it exerts at the bottom It's the same with water, the deeper you go, the more water is above you, and therefore the more pressure. |
Why can't we put illegal aliens on buses and take them back across the border immediately? | I know you are looking for logistics, and there will be logistical answers, but part of it is that the USA has obligations under both domestic and international law to accept genuine asylum seekers, for example those fleeing gang violence or state oppression in their home countries. Rights of asylum apply whether or no... |
- Why do captchas need to look like they're a
ransom note with each letter clipped from a
different magazine? | CAPTCHA's help prevent people from using bots to make accounts really quickly. For instance, without CAPTCHA, someone can generate 1000's of reddit accounts which can then upvote some blatant advertisement/post to the top of the front page. The more complex they look, the harder it is for a computer to decrypt the mess... |
Why is mouth-breathing associated with being stupid? | I studied orofacial myology in college, which is the study of how the muscles and bones in the face work together. We learned that habitual mouth breathing lowers your blood oxygen levels, which can lead to a lower IQ. You're also more prone to getting sick and gum disease.People with Down syndrome often have breathing... |
If launching a satellite only costs about $100 million, why can't we all throw in a few bucks and have free satellite internet all over the globe? | Very little of the world's Internet traffic is carried by satellites, for a couple of reasons: * The latency is high .* The bandwidth is not limitless. There's only so much radio spectrum to go around, and if everyone on Earth was trying to talk to the satellites all the time, the speeds would not be impressive. |
How can some people argue that 9/11 was an inside job and no planes hit the twin towers when there is first person video of it happening? | Confirmation bias: _URL_1_ People will take evidence that supports their idea and discard or twist that which doesn't support it. Just like some anti-vaxxers, who don't like putting things they don't understand in their kids. Some 'scientist' comes up with fraudulent data in order to help some scam lawyers win cases ab... |
How does a flat tax favor the wealthy? | Nobody's actually come out and said the real truth: the poor don't pay taxes at the same rate as the wealthy. [Here's a historical effective tax rate] As you can see, the lowest quintile of the US paid just about 1.5% of their income in taxes. The highest quintile paid ~24% in taxes, and the highest 1% of earners are p... |
In the U.S., why are residents of Alaska and Hawaii many times ineligible to win sweepstakes? | Logistics. Usually if it's travel based or involves multiple shipments, companies will prohibit them due to the higher costs of travel and/or shipping. |
How come some ice cubes are soft and chewy, while most ice is hard and brittle? | Different ice machines either do or do not compress their ice nuggets to remove excess moisture from them after the ice is formed and before it is pushed out of the machine. I'm not sure about different ice shapes: cubes, shaved, crescent, or sphere. |
How does "gasoline" start off as dead-barney and end up ethanol (what is the process)? | took a while to figure out what you meant with dead-barney.for latecomers: dead Barney, as in dead dinosaurs, since Barney is a dinosaur children's character. side-note: oil is not made from dead dinosaurs, but rather dead plants from much further back than the dinosaurs. |
I love that T-Mobile does this, but how is allowing unlimited data for music streaming not a violation of NN? | Net neutrality says companies need to provide equal bandwidth access to all sites. T-Mobile is still providing equal bandwidth which conforms to NN. Data metering is different as you get a set amount of data you can use on any site. They just don't meter you for the music site they prefer. You're still able to use anot... |
how does US states go cashless when the federal government is spending so much in other countries? | The Federal Government spends about 35 billion on foreign aid. They spend the vast majority on citizens of the US, including citizens of New Mexico. When you start adding up all the transportation funds, student grants, and healthcare grants. They've spent far more on New Mexico than on all other countries combined. |
If humanity knows nothing about aliens, why is it so important that we find water on different planets if we have never proven they need water to survive? | To the best of our knowledge of biology, water is essential to life. Earth has a massive diversity of life, from living in volcanoes to the polar caps, but they all require water in some form to survive. Therefore, our best theory is that if there is water on an alien world, it greatly increases the odds of finding lif... |
How does a gas stove prevent the flame from going in? | You need three things to make fire: fuel, heat, and oxygen. The gas line is pressurized and full of just fuel. With no oxygen , the heat at the end can't ignite the gas inside. That's also why there's a gap between the exit and the flame; the gas has to disperse and mix with oxygen before it can ignite.Flame needs oxyg... |
Why can't we just cover a proportion of the desert with solar panels to provide the world with energy? | Short answer is, we could, but it's not entirely efficient, and it would require a big chunk of money, and we'd have to deploy *vastly* more than we'd want/need to make up for that inefficiency. Other people are saying electricity can't be stored. This is obviously false. Even taking aside batteries, electricity is jus... |
what's going on when a dialup modem screams and barks? What do those different kinds of sounds mean? | Short answer: Your telephone line connects to a switching system. The switching system is set up to read numbers based on the tones it hears. So those sounds are telling the switching system what number to dial to then connect you to the internet service provider . Once that connection is made, the signal is changed fr... |
Why are our reproductive organs packed together with our biowaste delivery systems? | Why is God a civil engineer? Well, who else would lay a wasteline through a recreational area? Sorry, couldn't help myself. No offence intended towards civil engineers!", 'Female humans are the deluxe model: separate orifices for urination, defecation, and reproduction. Males still time-share the urethra for urination ... |
Why is there so much dishonesty and mistrust in auto repair services? | As someone who was a mechanic for awhile, I was shocked to people's reactions when we told them what the problem with their vehicles were. Anything ranging from tires with belts showing, to missing vital suspension components or something hanging on by *literally* a thread. We had a sweet old lady on 4 tires that were ... |
Why aren't local weathermen doing more to explain the risks of climate change? | Because meteorology is about points in time, brief snapshots of *weather.* Climatology, which is the most appropriate field of study to study climate change, studies long periods of time, usually over years. This is a study of *climate.* They studied very different things in preparing for their careers, and while each ... |
Why did New York City merge multiple subway companies into one? | If I remember correctly, the first 2 subway systems were owned and operated by private companies, and the 3rd was by the city. Eventually the first 2 went out of business, so the government took them over because, well, somebody had to operate them--you can't have major infrastructure just shut down like that. Also, ha... |
If flying a plane or helicopter can be so simple using a controller or keyboard in a video game, why do their real controls need to be so elaborate? | Believe it or not, the controls in most conventional airplanes are not really so elaborate. For example, you have a control column or a joystick that rolls the plane left/right and pitches it up/down, just like the controller joystick. The rudders are there primarily to keep your turns coordinated , but this is not as ... |
How has the Roman roads lasted for thousands of years but we can't make our roads last no more than a few years without it starting to erode? | Modern roads are built of asphalt, which is a surprisingly soft material. It's essentially tar with sand and gravel mixed in. It's cheap, pliable, quick to lay down, doesn't require any extended curing time before traffic can start driving over it, is recyclable, and easy to remove. However, because it's soft, it's not... |
Why is it so difficult to fake a convincing sneeze? | The same reason you can almost always tell a person is faking their sleep based on breathing.It is an involuntary reflex. Mimicking something you don't do consciously is difficult. |
How does high blood pressure work in the body and why is it genetic? | If you're talking about hypertension as a chronic disease, there are lots of ideas out there about things like salt sensitivity, renal dysfunction, adrenal dysfunction, but to be honest we don't have any idea right now, it's one of the great mysteries of medicine. It's not as straightforward as we used to think. |
How facebook is exploiting our personal information? | Don't take me as authoritative, but from my understanding, it gives information we submit to advertisers so they can target advertisements at us. Ever notice that advertisements on FaceBook seem oddly specific to your interests? I know I have, and their giving information to them is why.When you see that your favourite... |
- Can somebody explain the Semi-Conservative Mechanism of DNA Replication? | Simply in DNA is double stranded. And during replication the strands splits and each strand gets another new strand so forming two new DNA's. This is called semi conservative model because half of the new DNA is conserved from the old DNA and only the other half is new |
How plants manage to fight viruses ? | > since it is already complicated for animals body to manage a virus infection, and it seems to me that they have a better equipment, how can plants reproduce that ? Animals have a two-part immune system, an innate immune system and an adaptive immune system with specialised immune cells. Plants mostly have something a... |
Why it is more pleasurable when somebody caresses you than when you caress yourself? | Isn't this similar to why you can't tickle yourself. It has to do with your mind expecting it I think. |
why is Kennedy such a big deal in the US? | A few reasons: * His family's storybook legacy. His father was a self-made tycoon . The rumors that this money was ill-gotten, and that his family was/is inextricably tied to the mob, only enhances that background. * He was the first Irish Catholic president. This was a huge deal at the time. This happened in the lifet... |
Why are there so few dinosaur movies like Jurassic Park when they kill it at the box office? | They don't, really. Big budget, entertaining, well-promoted movies kill it at the box office, and even then it's not a guarantee. And occasionally unexpected sleeper hits hit the jackpot, too. Jurassic Park movies fall under that definition in the first sentence, but for example the 3rd one was very underwhelming . Bes... |
If pain is the human body's way of preventing further damage, why does scratching get interpreted as a 'good' sensation, when it is destroying cells? | Scratching isn't always bad for you. Itchy need to scratch sensations also alert you to insects and parasites and scratching would remove them. Same reason dogs and bears scratch themselves. Scratching would also remove layers of grime from the body and let the skin breath. I also think our ancestor's skin was much muc... |
what does 'Without Prejudice' mean in an employment termination letter? | It's a legal expression, and has a number of meanings. > When used in a document or letter, without prejudice means that what follows cannot be used as evidence in a court case, cannot be taken as the signatory's last word on the subject matter, and cannot be used as a precedent. > > When a court case is dismissed, or ... |
Why socialism and socialist principles never really took hold in the US, unlike the rest of the world. | One thing I've always wondered is if the origin of the US has anything to do with its politics. The US started, in essence, because of massive distrust of the UK government. As a result, by and large Americans distrust government and have a much bigger fear of big government than people do in many countries. Conversely... |
Who and what determines when and where a new (pop) song will be played on the radio? | It's generally a combination of gut instinct by the program director, focus group research and the previous success of the producers and promoters involved. Radio stations in big cities decide what they want to play and many choose to experiment with certain new artists and labels. Some break through, others falter. Th... |
When injured, why do kids instantly start to cry where as an adult you just scream (and or curse)? | Crying is a distress sound we make, as social animals it's used to alert other members of our pack to the fact that we are in distress/danger ect. Children do it more often because they need to inform their parents when they are in distress because they have no way to dictate themselves weather or not something is a sm... |
why do some female smokers develop a deep smoker's voice while others still have maintain a "normal" voice. | I read an article on this exact subject not too long ago! Sorry I don't have a source but A HUGE part of it is genes. Some people have genes that make them incredibly immune to smoking effects compared to other people.This goes for men too. My brothers voice changed drastically after he had been smoking a couple years. |
Why was the US happy to invade Iraq over supposed weapons of mass destruction, however now that North Korea are literally shouting about how they have WMDs, the US is not considering it? | North Korea borders South Korea, which is a major US ally. If war breaks out, we can almost certainly expect South Korea to take damage. North Korea would likely be defeated by the US very quickly, but they could do a lot of harm before they're taken out. Even a pre-emptive strike would likely result in some harsh dama... |
Why does SWAT sometimes wear face masks? | Sometime's it's to protect from inhalants, but if that's the case then they'll always wear gas masks if they have them. Usually it's for the same reason that criminals do. To avoid being identified. If a vengeful person recognizes them, then they could be put in danger. |
Julius Caesar is by many considered the greatest man to ever live, but what did he accomplish? What was his direct impact on history? | I've never ever heard him described as the greatest person who ever lived, who's said that? |
If I, a person with no criminal record, were to go out and kill a random person, how would the Police catch me? | They would probably have a hard time. That's why careful serial killers can be so successful. But the thing is, that almost never happens. There's just no part of human psychology that allows someone to murder random people. Even people who have no empathy or remorse don't murder, because it's difficult and risky, and ... |
. Do we have reason to believe AI may have personalities once they surpass human cognitive function? | Wouldn't the racist teenage nazi Twitter bot that was recently created and taken down answer this question? I would think even after highly refined, any ai would learn from its environment and develop a personality. Or virtuality if you will. |
After armageddon, how do I start mining for metals to start the new bronze or iron age? | You don't. Most of the metals at the time were taken from surface deposits, which are pretty much entirely depleted today. |
Why Do Musicians Leave the Stage before Encores if They are Immediately Coming Right Back? | I think it often, nowadays, acts as a delineation between 'the set' and 'the bonus bit'. The encore section can be used to have fun, re-jig old material or whatever without it being judged as part of the show proper. |
What are the risks or ramifications for getting a home mortgage when you only plan to live there less than 5 years? | It depends on a lot of factors. I was in my first home for 5 years, I think I pocketed $1000. Add in all of the work I did and I was probably in the hole $5000. My last home I had for 3 years and walked away with a check for $30,000. It's all about the market. We bought that one when the housing market was way down and... |
Why were zeppelins a viable option in the war? | They had multiple ballonets and a single bullet hole wouldn't cause them to go down *instantly*. It actually took incendiary bullets to bring them down. And unlike airplanes, they could typically afford a significant defensive armament. Also, most stray bullets don't travel high up in the air. |
Why does gasoline smell so good if it's so toxic? | That's only true for natural gas. As in gas for your heater slash stove which has thiols added to it. It's important to add the thiols because natural gas is a gas at room temperature so if you have a leak it would get everywhere without you noticing if you couldn't smell it. On the other hand the gas in your car smell... |
Is it possible to lose weight by having a weekly caloric limit instead of a daily one? | Yes, but you're more likely to fail adhering to the limit by using it as an ecuse to go over your daily average and then not being able to stay under it to compensate. |
Why is that in all pictures wee see of planets and moons we always see the crater only and never see the meteor, boulder or whatever caused the crater sitting on the collision site? | Not really. Anything impact that can create a crater big enough to be seen from orbit, will also be more than energetic enough to completely obliterate the meteorite. As an example, take the Hoba meteorite. It's the largest ever found on Earth, but it left no crater. _URL_3_ |
Would it be catastrophic if it snowed in a zone that never had snow before? | I live in Southern California and we get snow once every several years. It's catastrophic to traffic, and everyone from states that get regular snow think we're all morons for being amazed by it, but that's all. |
Why are emojis and other text messaging icons becoming increasingly widespread, yet we still have no ability to use more common text editing features like italics, bold, and underlining? | I'm really curious about this too, so sorry I'm not giving an answer. I would just like to point out that Android 4.0+ has full support for Emoji. Not all of the keyboards do, but support is spreading |
If a President-elect dies or resigns before being sworn in, who then becomes President? | That's never been tested, and it would almost certainly become a major constitutional crisis. The automatic assumption that the VP would become president not necessarily what would happen, because that person isn't actually the VP yet. As far as it happening in the near future, well, I hear Jodie Foster really, REALLY ... |
How long does it take a renewable resource device (wind turbine) to pay off the initial carbon foorprint from producing that device? | This questions requires the use of [life cycle assessment] . For this type of question you often assume that the existing energy infrastructure has already been constructed and therefore do not count the embodied emissions traditional power plants also have. You could assume two options where you build either coal fire... |
why do people go insane if they are in isolation for a long time? | Its like a less intense form of sensory deprivaton, or how animals in tiny zoo cages pace and go crazy, too. We need a certain amount of stimulus and variety; it's what our brains have evolved to deal with. |
Can I start a company named Tesla Mattresses? Will I be hunted down by Tesla Motors? | > I understand a tesla is an SI unit so can't be copyrighted? Trademark is what you are talking about, and it isn't true that it can't be claimed by a company. But you could make the mattress company because you would be in a completely different industry and nobody would reasonably confuse the electric car manufacture... |

Among criminals, why does it seem to be more acceptable to murder each other than to snitch? | I think what you're referring to is more the case in prison itself. Guys doing long stretches have nothing to lose so you don't want to get on their bad side . |
Why do super famous actors/directors etc still hire talent agents and managers? Wouldn't their immense fame be enough to get them studios pitching ideas to them, let alone audition requests. | When you're young and inexperianced, an agent is a 'foot in the door' of the industry, because they know people, and can get your name out there etc. when you're famous, experianced and successful, an agent is more like a buffer for the many calls and negotiations that must take place to get you into a desirable role. |
Why ministers (in the UK anyway) who have no qualifications or background in an area of expertise eg Heath/education are allowed to dictate how that area is run? | For a good idea of British Politics watch Yes Minister and Yes Prime Minister. Quite a few politicians have said it's quite accurate to the the real goings on in Whitehall. It's also very funny. |
Why is the CIA Torture Report such a big deal? | Dianne Feinstein is the head of the Senate Select Committee on Intelligence, which generally oversees the CIA. And yes, we have known that some of that torture was going on, but earlier this year, Congress voted to gather all of the data on torturing since 9/11, but it was found to be ineffective and inhumane. There ar... |
Why aren't sidewalks slightly higher in the middle so that water would drain to the side? | Sidewalks occasionally have a slight grade, but generally it's pretty level. ADA requirements for sidewalks is about a 1% grade, which is almost nothing. Just enough to let the water drain off, but not much else. Since building a 1% grade is pretty difficult, building a flat form, and pouring concrete is the easiest an... |
Why do medication companies make commercials when they have to spend most of the commercial listing all the unappealing side effects people have experienced? | FDA requires all direct to consumer drug commercials to list most common side effects if the commercials state the FDA approved indications. If the commercials do not mention the FDA approved indications, they don't have to list common side effects. Lunesta commercial is an example. All it shows is the name of the drug... |
How come after Humans see a bug of some sorts (ex. Spider) they get feelings that the bug is crawling on them when it's really not | As another redditor has said, you body ignores extraneous stimuli unless it thinks it's relevant. This is also why phantom phone vibrations are now a thing.Fun fact - the sensation that something is crawling under your skin is known as formication |
Why does water evaporate from a cup if I leave it outside, even though it's only 30°C? | What we know as temperature is technically a measurement of the AVERAGE speed and energy of atoms found in an area. Because it's only a measure of average, it would mean that some atoms in the area will travel faster and slower than the average. So those atoms travel significantly faster will still evaporate out.Boilin... |
How does an elevator get put in its "tube"? Bonus points for telling me, how safe they are. | Elevators are very, very safe. Short of the cable itself and the emergency brakes getting sabotaged it's basically impossible for a cable driven elevator to fall all the way down the shaft at a speed that will kill you. |
What's the problem with thawing meat by running it under a running stream of water? | There is no problem putting meat in a bowl and running water over it. Source: _URL_0_ I'm just saying isn't it how most people unthaw stuff? Plus it abides by food safety standards, but of course that's for the US.Thawing in the fridge overnight is the best way, but there is nothing wrong with doing it over running wat... |
What is it about freezing inoperable hard drives that makes them work again? | If your hard drive is suffering from [stiction], then freezing it may cause the metal parts inside to contract enough to relieve the problem. However, freezing your hard drive is not a silver bullet - it won't do anything at all to help if you have burned out circuitry or such. Also, it can do more harm than good if yo... |
How does a plane calculate its altitude? | So remember that time we drove up that really big hill and your head felt really funny until your ears popped?Your ears popped because the air is thinner at the top of the mountain than at the bottom and all the thick air bunched up inside of your head was trying to get out! We built a mechanical ear that, instead of p... |
How did "modern" disorders like Autism, OCD, and ADHD arise? | While it's possible that some things that have changed in modern times has lead to it occurring more often, it's absolutely certain that many diseases and conditions that are very common now existed back in the past, but there were much bigger issues that people had to deal with . It's entirely possible these disorders... |
Why do humans cry or draw away when feeling pain instead of getting angry like a bull or boar? Why do we cry in general when sad or in pain? | Okay, explain like you are five. When we are at that age in development we have a great deal of exploration to do with our emotional selves. It is why you will see different responses when a child falls and is not really hurt, it is a cry for attention. Some event happened, it hurt, if I cry someone will come to comfor... |
Why is Franklin D. Roosevelt considered by many historians to be one of the greatest presidents of all time? | You pretty much named it, he went from the Great Depression to building the US in to an industrial and economic powerhouse that won WWII. On thing to understand is that before WWII, the US had a bit of an inferiority complex and often still viewed Europe as the grown ups in the room. WWII firmly established the US as t... |
Why reading a book while driving make us feel like we need to throw up | Are there any good statistics about how many people feel sick while reading in a car? I'm in my 30's and since I was a child I read while riding in the car, and I've never felt sick. I could see it either being some people are affected and some aren't, or there is a way to read in the car that doesn't make you sick and... |
why was the invasion of normandy(d-day) important ? and why did we have to attack such a heavily fortified german base ? | Short answer, we had to land SOMEWHERE in France to actually push back the Nazi's, and there were a couple of good targets. We actually faked an invasion at a different beach using mock up tanks and ships and things, and tried to misdirect the Nazi attention elsewhere and draw them off. We shelled and bombed the beach ... |
What happens to Social Security Numbers after the owner has died? | Since there's only a finite amount of numbers we can conceive of, we try to re-use them for people born after the original owner died. In the case of followers of Eastern Mysticism we try to link a soul's earlier SSN to their reborn identity.The SS# feels immense heartbreak. After an eternity of depression, alcohol, dr... |
Why can't I copyright my e-mail address and sue anyone who uses it without permission? | Because that's not what copyright does. Copyright doesn't restrict people's ability to use your IP, it restricts people's ability to duplicate it. |
Why is it so scary to record yourself staring directly into the lens of a camera and watching it afterwards? | Look in a mirror as well, especially in low light. You will get an uncanny feeling and, if the lighting is bad, you will notice your facial features begin to change. This is supposedly attributed to the [Troxler Effect] but I would dispute that since it has more to do with the brain constructing a new image instead of ... |
Why is American healthcare dependent on a job? | No universal care, so one has to buy it privately, as you do. Many employers started to offer it as a perk in lieu of salary compensation, and with larger pools they got better rates in some cases. It basically morphed into the customary arrangement, but over the past few decades it is slowly reverting to fewer jobs of... |
Could a radio antenna be set up to broadcast in the visible spectrum? | > I'm not talking about heating up an antenna so much that it glows; Yeah, you are. Electromagnetic radiation at 500 terahertz frequency is sort of a yellow-orange color. Radio is the same sort of thing as visible light just at a different frequency. |
Why can a huge human whack a tiny fly mid air and its seemingly unhurt? | As with pretty much any question about why small things behave differently than big things, it's the square-cube law. Let's say the fly is 1cm long, so roughly 180 times shorter than you. That means the cross-section of e.g. its legs and thus its toughness is 180^2 times smaller. However, it also means its mass is 180^... |
How do companies know whether or not their commercial is good? | Companies show their commercials to a test audience or multiple test audiences before airing them. This ensures that their product is liked by the people who they're trying to sell it to. Generally if they get a more negative response to a commercial they'll send it back to the drawing board and come up with a better o... |
Why NAACP and other voter orgs are Voter ID laws? | You need to consider the opposite question. Is voter fraud so prevalent that we need new laws to combat it? There is very little evidence that voter fraud exists to a degree that would influence elections. If someone is trying to solve a problem that doesn't exist, you need to ask if they have ulterior motives. |
Now that Russia invaded the Ukraine is World War 3 inevitable? | Obama won't do anything, he simply doesn't have the character to act. Putin knows this and has been testing his boundaries for the last 4 months. He will continue to push into Ukraine unencumbered. Although this move may not start a major world war, it will start a war in the region. It's not necessarily about Ukraine,... |
Why do we NEED bees? | Well you see Blackbird027, when two people love each other very much, they often interact with each other in a way which makes a third person |
Why is it that after a long night of heavy drinking, I wake up significantly earlier than if I went to bed completely sober? | > wide awake, no hangover, You're young aren't you? Don't worry, that'll all start changing before you know it. You'll still wake up at 6 am but you'll feel like you're trapped in a hell between life and death for between all day and three days. |
Why can human skin endure near frozen water for minutes without repercussions, but not endure boiling water without getting third degree burns? | It's a question of degree, literally.If it was cold enough the damage would be close to instantaneous. |
the film "Inception". | It is largely based on a Dutch concept, called [The Droste Effect] Basically, there are wheels within wheels, and perceived realities within perceived realities. The movie itself is, imho, a total diappointment. Too many special effects, a story line no sane person can follow, uninteresting supporting roles, the music ... |
Why do storage devices have capacities that are multiples of 8? | In fact, this is related to the powers of 2. Because computers use a binary language, the data is translated as a combination of different patterns with only these two options. Think like this: if you had a question, you would had only two possible answers, true or false, and you would need just one digit to answer it,... |
Why does Westboro Baptist Church protest our soldier's funeral? | They are a special form of crazy, however, freedom of religion and speech and assembly apply equally to them. You can't make exception to these freedoms, because once you say they are no longer valid for a group, you can say it for any group. If freedom of speech means you can't say anything that would cause you to los... |
How could theatre patrons hear the actors on stage before modern electricity? If it has to do with room acoustics, then why are microphones needed now? | back then, they also didn't have the huge ass theater rooms that can sit 10-20k ppl.I play in the orchestra for a music theatre all the time. Occasionally a mic will malfunction. This is the test of experienced vs inexperienced actors. The experienced will just start projecting, and the show goes on as usual . Inexperi... |
Why can we fit a gigabyte inside of a space that can fit 64 gigabytes of storage in the exact same amount of space? (SD cards and solid state drives | Storage devices have to be made in standard sizes in order to properly fit into the slots/bays that devices have for them, so they can't just make the ones with less capacity physically smaller.SD cards and solid state drives use solid-state circuitry known as flash memory to store their data. These circuits are tiny w... |
How is it that in 2015, we can't use science to accurately recreate Stradivarius violins? | We'd need to know what we were recreating. Where the wood came from and what the weather was like every single year that those trees grew, what chemicals were applied in what quantities and how, where was it stored and for how long? We don't know a lot of those things. |
Why police raid LEGAL medical Marijuana dispensaries? | Just because you're selling medical marijuana doesn't mean you're not committing any other crimes. Several recent busts have had nothing to do with pot, the establishments were also selling other substances or laundering money for outside entrepreneurs. Don't presume that running a pot business will make you magically ... |
Why is facial structure (roughly) the same (eyes then nose then mouth) on so many different animals even though we evolved independently? | The cranium essentially developed once, back in the Cambrian some 525 million years ago, and while the descendants of those fish have made lots of variations on the theme most of the basic plan remains intact from back then. Aside from that it's mostly convergent evolution with different groups drawing the same advanta... |
why do babies throw up/spit up so often compared to adults? | Besides what /u/knobcopter said, babies tend to swallow a **lot** of air if whoever is feeding them isn't paying attention. Since saliva and milk make that air into sticky bubbles, they can't belch it out like adults. Take a couple ounces of milk and put it in a large bottle with a tight lid. Shake the hell out of it f... |
How do moles appear on your body? | Sometimes if you're not careful, the little bastards can crawl up your leg. I've had this happen to me a few times in the past, and now I only wear shorts. Why? Little known fact- moles have claws that are perfectly adapted for digging holes in the dirt; an unfortunate side effect is that they're also well suited for h... |
; Why would a lawyer choose to represent someone that was guilty? | Well, there are a number of factors in play. First, we have a system which says that everybody is entitled to a fair trial to determine whether they are guilty. To that end, I think it's only right and proper that somebody represents them. The alternative would necessarily end up with some innocent people not being rep... |
Why is the use of fully automated weapons (robots) such a moral issue? | The fear is in creating machines that take it upon themselves to determine what should and should not be destroyed. Drones, missiles, bombs we have no shortage of things that can kill people, but they all require a person to make the final decision to shoot. Self-guided weapons also have moral issues: the same question... |
Why is having high value of a currency bad? | Using simple numbers: Let's say Japanese citizens have a contract with China to pay China 100 yen a day for rights to fish in the East China sea. If the yen is not valuable, then the man has to work 2 hours to make 100 yen. If the yen is very valuable, he has to work 4 hours to make 100 yen. The purchasing power per ho... |
How did the Japanese in the 1900s conquer so much of China? | I'm about to log off but the gist of all these types of conquests is industrialized/more advanced nations vs non-industrialized. There are many many examples of this. Look no further than Spain and the Americas. Also well trained and veteran regulators > irregulars/militia. China did not have a centralized and strong a... |
why did Christian slavetraders think it was okay what they where doing while the bible says God punished the Egyptians for enslaving the Jews? | There's a whole section of the bible on how to treat slaves in the New Testament. The bible was pro-slavery. It was just anti-hebrew slavery as far as Exodus goes. |
Why exactly does it hurt when soap comes in contact with a bruise or an inflamed part of the body? | Not a direct answer to your question, but it's a pretty neat fact: When you pour alcohol on a wound it burns, not because of anything in the alcohol, but because the alcohol causes the receptors that detect temperature to lower their threshold for heat, thus making something that is not really that hot feel very hot, o... |
