Why do computers get slow?
If you ask my mom, it's because you have too many icons on the desktop or because you've installed too many programs.CCleaner and Malwarebytes are my go-to programs for slow PCs. CCleaner seriously is the bees kneesIf new software comes out, it may not be designed to run well on your old pc. So over time developers will raise their standard for what they expect people to have. If you fall behind programs will seem slow.Barring physical failure, computers never get slow. Whatever speed the hardware is running at when you purchased it will always be the speed that it's running. It will never slow down.A lot of people like to put 2 antivirus on and then they both check eachother actions and the computer starts to shit out from there.
How can anyone survive as an 'out of work actor' in New York City or LA when people with full time degree-required jobs can barely afford to live there?
By being young and single and living like shit, knowing how great things will be once you hit it big. It is not unlike going to college. You'll typically have a part-time job or two, and spend all of your free time pursuing acting. You will also likely have several roommates. Plus, there are a lot of acting and acting-ish jobs in those cities. They don't pay well and aren't real steady, but if you are young and good looking and work at it, you can be an extra in a Valtrex commercial or demonstrate a new kitchen gadget in grocery stores without too much trouble.
How can Netflix put all kinds of cool TV shows online for less than $10/month with no commercials when cable companies charge people $75/month or more and you do have to watch commercials?
Weren't you the asshole who made a kid reformat his hard drive?", '> Is cable a giant rip off Yes. [Educational video]', "I've seen a lot of the major points brought up here: infrastructure, sports, watching live, etc. These are totally huge factors, but no post I've seen has brought up the simple anti-competitive economics of the telecommunications companies. Where I live, if I want both TV and internet, I have to use Comcast. I have no choice unless I want to get both from separate providers. Netflix on the other hand, has competitors. Hulu, or Amazon instant video for example. In a competitive market, price matters. In a market where you have little choice, it doesn't.
Suggestion/request: could we slow down a bit on the slightly silly and really obvious questions?
Asking here is much better than googling, because if there is something you don't understand you can just ask for a better explanation. also, what you think is obvious is not always obvious to others. I recently learned that not everyone knew that we are closer to the sun in the winter than we are in the summer, which I thought was common knowledge. But it would be nice if people could use the search function
Why Do Divers Have to Decompress Before Surfacing?
When you dive, gasses dissolve in your blood much the same way fizz dissolves in fizzy drinks. When you ascend too fast, the gas comes out in your blood as bubbles, which can cause a lot of damage, mostly by cutting off circulation. This is just like taking the top off a bottle of pop too quickly. Do it slowly and it's more controlled - any bubbles are small and easily dispersed, but mostly the gases have time to be exhaled from the lungs instead. This process, as you've noted, can take many hours. There are things you can do to help. You can use gases which are less soluble or which come out of solution more easily.
Greece is on the brink of leaving the Euro so why is everyone withdrawing their money from ATMs?
People are withdrawing their money because they are afraid the banks are going to go out of business and/or the government is going to require them to pay taxes on their bank accounts. If they have euros and Greece converts to the drachma, they'll still be able to use the euros to buy things.
If police officers are trained in physical combat, why are there so many stories of them just shooting an unarmed suspect instead of trying to hold them down?
The suspects are usually found to be unarmed after the shooting. If the police believe you are trying to access a concealed weapon, that's when they use force.
Why does Hulu play ads for paying members, when Netflix offers TV shows ad free?
What I haven't see here is this. For syndication and other purposes, it's much easier to get that for old shows than shows that have just been aired.
Why do spaceships always take off from warm places like Florida?
They don't! A couple of weeks ago the UK Space Agency [announced] it was planning to build a new spaceport on the North coast of Scotland. There's also plans in the works to build one in Sweden. Historically, only three places have been used to launch people into space ; Florida, Kazakhstan, the Gobi desert, Inner Mongolia - by the USA, Russia/USSR and China respectively. Satellite launches are [a bit more spread out]; with some from North-West Russia, French Guiana, Japan, India, California, Virginia lots of places. Being hot isn't important. Being near the Equator can be useful if you're trying to get things into an equatorial orbit, as you get an extra push from the spin of the Earth. Being near water is good - if you launch over water you've got a big area to crash into if things go wrong. Being in a nice empty area is also good - it gives you lots of space for your facilities. Florida has all of these things. But if you're heading for other types of orbit , an Equatorial launch site isn't necessarily that good - hence spaceports near the poles .
Why haven't humans discovered/invented a better way to wash their bodies? And if there is a known better way, why do most still shower?
There's always a 'better' way to do something, but it usually involves a lot more money. I'm sure some sort of instant cleaning pod could be invented, but it would be pointless and very expensive.I heard you can cut your bathing time in half by microwaving your iPhone for 45 seconds
With the Earth spinning at roughly 1000mph, how the hell can we see stars and other far away objects? Shouldn't everything just be a blur?
Things blur because they set off photoreceptors all across your retina in really quick succession. Things that blur must have a large *angular* velocity about your eye. That is, the angle to them from the middle of your vision changes quickly. A car driving away from you on the highway at 100 mph doesn't blur, but one driving perpendicular to you at 25 would if you stood close enough. If you back up, the angle to that car doesn't change very fast. It's moving far, but it's really far away, so you don't have to turn your head to see it. Since the angle isn't changing very fast, it's basically in the same spot as far as your eye cares. The same thing happens with stars. They're going really fast relative to us, but they're so far away that they're not whizzing around us in circles very quickly. _URL_4_", 'the earth is not spinning at 1000mph. your mixing terms that don't "work" together which is causing you to be understandably confused. the earth spins at 1 revolution per day. its spinning so slowly that it takes more than 30 seconds for a "star" to blur into a "streak" instead of a "point" in a photograph. which is why non tracked photo's are typically limited to no more than 30 seconds of exposure. the "SURFACE" of the earth is moving at 1000mph. 1000mph is quite slow in reality. it is only fast when compared to our relatively snails pace speeds we deal with locally.In comparison to the vast distance , 1000 miles per hour is not even moving. If you live in a valley or near a mountain range, look at it as you drive. I am only about 100 miles away from those mountains, yet they don't blur when I drive 60 miles per hour. Put that in scale with 1,000,000,000 : 1000, and it's impossible to notice.
Is the awareness that you will die learned through observation or is it instinctual?
This is a brilliant question, I must say. I'd have to say that it's definitely a learned behavior. There's no reason for there to be an instinct involving death because instinct is specifically there to help you thrive. If your instinct was telling you you're going to die someday, it wouldn't be a very effective instinct, if you ask me.
Why does American fuel have less octane than European fuel? Aren't we driving sort of the same models that should require the same kind of fuel?
I just want to point out in SOME vehicles, higher octane can get you better gas milage for example. Take the modern VW GTI. It accepts 87 but the manual says if you put 91 it will advance the timing, which addes HP. Some guy on YouTube dynod it, about a 15 hp difference. More power at the same rev range mean you don't press your foot down quite as hard to go the same speed. This is mostly for turbo motors. NA motors don't make the same gains with octane usually.
Why is overwatched so hyped up? It seems to be just a reskin of TF2.
Another person has already pointed out: Blizzard. But, a big part of it is the fact that they have made several Disney/Pixar quality short videos that really established the lore behind it while making developing the character's their characters. I mean, I hate shooters and even I was hyped while seeing all those trailers! Next to that, Team Fortress 2 has been around for 9 years now. It was still popular, yeah, because nothing of the same quality had come up yet. This is actually really innovating. If they bring out an animated series, or just a movie, I would watch it as soon as I could. Edit: I did say it was innovating but didn't say why: There are more characters, more play styles, really awesome abilities and it's really colourful.
What is Love and why do people feel different when they are in love?
Love is a series of chemical reactions in the brain. In nature, it exists to give the males in a group an incentive to protect specific females and thereby protect the young. This is the best scientific, 5 year old compatible explanation I can give ; if you're looking for an emotional explanation I can't really help you.The English word "Love" means far too many different things to answer your question as asked. "in love" narrows it down, but perhaps you can give us more guidance on what you really mean.You'll know what love is when you're in it :)
If it's so bad for humans to carry a child at such a young age, then why are we capable of it so young?
One of our successes is that we're flexible and adaptable. It's not ideal for a person to be pregnant at age 11, similarly it's not ideal for a person to be pregnant at age 45, but having the ability to do so is a great advantage. Remember that evolution isn't about individuals, it's about the genes. If the genes are passed on, then it's successful. There will come situations where pregnancy at age 11 is desirable from an evolutionary POV and there will be situations where pregnancy at age 45 is desirable from an evolution POV. Those situations just doesn't occur in our modern world. For example a marauding tribe who comes and rapes another tribe will pass on their genes indiscriminately, and in doing so, it will pass on the genes of the mother as well. So genes with a large span of fertility will propagate. That 11 year old who is fertile, if she survives, will have passed on her genes whereas that 12 year old who is not yet fertile will not. Just one example.
How come the F-35 program cost way more to develop than the F-22 despite being generally less technologically advanced?
Partially due to inflation, and also because the F-35 program is really creating three different planes, for the Air Force, Navy, and Marine Corps, so there's a lot more to figure out.
Why do Republicans hate Obamacare so much?
It's not like only republicans hate obamacare. Many people from all political affiliation are increasingly disapproving of the law now that they are actually finding out what the law entails.
Why can you see a full preview of your video your editing yet it takes a really long time to render it?
When you edit your video, you're not actually editing anything at all, except for the project file. It may look as if you're taking video files, cutting them into pieces and adding them together to make a video, but you're not: you're just adding commands to a project file. When you preview your video, it's just looking up the video files listed in the project file, and playing them as instructed by the project file. Depending on the source material, the video editor, how good your graphics card is and so on, you may even be seeing a low-resolution version, because it's quicker to render. Often frames are being dropped all over the place, and any special effects you've added are just rough approximations of what you'll get. Rendering the video takes a lot more effort than just playing portions of video clips one after the other. The video editor has to take the original files and, following the instructions in the project file, find the portions that are needed and copy over the data to the new file, converting it into the exact format you specified, pretty much frame by frame.
Why does some flatulence feel like it comes out as a bubble?
Every wonder why your poop is tapered?So your b-hole doesn't SLAM shut Yeah. I'm 5.Because it is a bubble. Just like "air" in water, your fart is a fluid in another fluid. As for the feeling, it can be due to a tiny bubble moving through, or maybe you're talking about those warm ones which are just slow-moving farts. keep in mind that your anus has some very sensitive muscles and you feel *everything*So you have this thing called a butthole. I like to refer to it as your "South Mouth". Now this "South Mouth" is a wonderous thing. When you toot, fart, squeeze one out, pass gas, or flatuate it flaps.If your ass cheeks are sweaty and stuck together they'll tend to stick to one another as the gas passed through creating the sensation of a bubble.Even better question. Why do some farts burn a little? Like the pre-diarrhea farts?i love it when a bubble runs up my butt crack :)
How are school lockdowns effective?
Lockdowns aren't just for shooters and the like. Sometimes a parent with no legal guardianship will come to a school to take a child they don't legally have the right to take. Locking down under those circumstances is entirely effective. We also locked down when there was a bad accident sometimes to keep the students from panicking, to save the student from unnecessary embarrassment , and to make it easier for emergency personal to do their job.
Why isn't there a limit for donations from super pacs but there is for personal donations?
Super PACs spend money others give them. They don't donate money to campaigns. The Supreme court ruled that the activity that Super PACs do counts as free speech, so there is no limit on it.
With everything going automated, how are we supposed to make a living?
50 years ago there were no personal computers. Now they're ubiquitous; they did make some jobs obsolete , but also created millions of more by enabling people to do things they couldn't before , as well as creating tens of millions of jobs in IT ", 'Pick a job that is difficult to automate. This includes jobs where you have to analyze AND derive meaning where there is a lot of grey area.
what does it feel like for an alcoholic or other substance abuser to resist the drug?
It feels like you can't do anything without the substance - we'll say alcohol. You don't want to eat without drinking, watch TV without drinking, hang out with people without drinking. The substance defines the things you do. So quitting is such a challenge because you feel directionless without being able to indulge in the thing that has defined your activities. This feeling dissipates the longer you're sober, but never fully goes away. When you have a drink after a long time of wanting one but not allowing yourself, it feels great. You're smiling, talking, doing all the things you used to do again. Moderation is the most difficult goal for an addict of any kind.
Why is asset forfeiture allowed despite Fourth Amendment protections against seizures?
Followup: How do civil forfeiture laws allow law enforcement to seize and keep property without charging any crime despite the 5th amendment's due process clause?
Why do some people have the ability to consume extremely spicy food effortlessly while others can't put down something like mild salsa? is it practice?
The short of it is, resistance. I've been eating spicy foods my entire life. The result of that is I have to eat things that are simply beyond most people to burn myself. Your body like anything gets used to something over time. I enjoy spicy food not simply for the burn, but for the flavors and the endorphin rush they cause. I actually despise these people who go around making fools of themselves eating spicy foods way beyond their tolerance. There is no enjoyment to that and you aren't more of a man for doing it.
How do we know that the history we have recorded is accurate?
We don't, and it isn't. We do the best we can with what we have, understanding that history isn't recorded by some omniscient narrator, but flawed, subjective human beings.
With all the stuff happening around YouTube’s policy towards content creators, why can’t they move/create a new alternative to YouTube?
Moving to a new platform would simply have the effect of moving the problem. The issue is not YouTube arbitrarily deciding to punish some people by demonetizing their videos: the issue is advertisers not wanting to have their products associated with contentious things like terrorism, political extremism, violence and so on. If content creators moved en masse to a new platform -- they'd have to do it en masse if they want to compete with YouTube -- advertisers would start telling that platform they don't want their products associated with those things.
Why must there always be economic growth?
These people are literally all wrong. The real answer depends what level you're referring to. If you're talking a global scale, it's because of the increase in technology and the decrease of inefficiency in the market. Tech increase means any advancement that increases real output, such as a better way to farm or a way to make better houses. Decrease in market inefficiency are things such as removing minimum wages, tariffs, etc. Note, these things may lead to a worse economy in one country, but the global economy as a whole will constantly grow. People saying bullshit about capitalism and unsustainable growth are completely misinterpreting Marx. If you're referring to an individual country level, then growth occurs due to the things mentioned above, but also at the expense of other countries. This much is self explanatory. The reason the economy shrinking is bad is because technology is always increasing such that real output of the entire global system is always increasing. If one country is sitting there and staying flat or shrinking, that means it is losing relative economic strength compared to other countries. This tends to have a compounding effect as the country is forced to do things that cause the economy to become even weaker. An example is minimum wage. If the US wasn't hemorrhaging high skilled labor then the US may not need to have to increase its minimum wage to bring the lowest standard deviation of the population to livable wages. But alas the US is shitting jobs like mad and Walmart workers get paid scraps so the US has to introduce heavy inefficiency to the system by raising the minimum wage. Edit: Please note I'm being 100% serious about everyone else saying a load of bullshit. Money doesn't inflate for fun. It can deflate just as easily if you feel like making it that way, a la bitcoin. Saying money magically decreases in value just for the sake of it is not real economics. There has to be some kind of underlying reason, as money is not some kind of natural force of the physical world.
Why don't the ELI5 mods let a question be re-asked if it has not been answered in years?
The definition of a second-world country from a year ago isn't any more or less accurate than the definition from right this second. It doesn't do anybody any good to answer it again. It took me two seconds of using the search bar to find the answer to that question; if that's too much work for you I don't know what to tell you.
Why does air smell different when it's colder?
Smell is particles evaporating. In cold air, they don't evaporate so much, so the smells are less intense. This is only a guess, but might have some influence on the overall smell-feel.
Why are microaggressions a thing? Every example I've seen are people just looking way to deep into something to the point where they find it offensive.
You really are a credit to your race." I take no offense, because I understand where they are coming from and at the same time the surprise in their voice is what is disheartening. As if they don't expect me to be able to do those things.
Why are radios so complicated? Why can't someone just plug an antenna into a speaker or oscilloscope and catch a frequency?
Radios have to two things: * latch on to a single frequency while eliminating all the others* amplify that very weak signal into something audible That's the part that is going on between antenna and speaker.
If a fever is the body's way of fighting viruses and bacteria, why do we treat them with Tylenol or ibuprofen?
The general idea is that the benefits of the fever don't outweigh the effect. This isn't true if you lived in the wilderness where an extra day of illness could mean starvation and disease was a serious risk. However we live in the modern world where the flu probably won't kill you and an extra day of illness is far less dangerous.I had the same question and my doctor told me that keeping your body in a fever and experiencing pain are very stressful to your body. You treat the fever so that you can be comfortable and rest and nap more efficiently while your body fights the infection, or just waits for it to go away.You take the pain killers to increase comfort by reducing the symptoms. Although also an anti inflammatory in the case of a fever it's generally to make you more comfortable. It doesn't actually directly fight the illness. Example: Tylenol doesn't make the cause of a headache go away but it relieves the symptom.
Why can't the whole world join forces to end the Syrian conflicts?
The conflict in Syria sprouted out of a civil war between rebel forces and the current governmental regime. Now we have ISIS as a factor, as well as the United States and Russia essentially acting out what is known as a proxy war: each superpower backs a certain side, and essentially get to war against each other without expending as many of their own troops and resources.So now, favoring either side of the conflict in an attempt to bring peace essentially means publicly opposing one of the two most powerful nations in the world, which no one is willing to do.Also, until the threat of ISIS made it a bit more of a global issue, most nations had no interest in getting involved, preferring to let the country work out it's own issues, and unless human rights violations are occuring, the U.N. has little right to step in.Hope this helped!
Why my computer can be running along fine, and then suddenly slow to a crawl for a few minutes?
At 4:15am every day, my computer's hard drive starts reading and writing a bunch. Several months ago, when I first noticed it, I went into Task Manager and then Resource Monitor. The computer was also acting particularly sluggish. All of the hard drive activity was coming from the file indexing service. Researching it, I discovered the things like Windows updates, file indexing service, and defrag are all scheduled to run in windows task scheduler. I love that Windows is capable of doing these thing automatically in the background. I can very easily disable or reschedule them. I keep them enable because I know myself and updates/defrag won't get done otherwise.
Why do all radio stations end with an odd number after the decimal?
The radio stations have their frequencies assigned by the federal regulator which only assigns dot-odd frequencies. The channel spacing of 0.2 MHz is larger than is really necessary but does help reduce interference. It's a US specific convention, other countries may assign differently, for example in the UK stations may broadcast on either dot-odd or dot-even frequencies, for example 96.4 or 105.7.Depends on the region.Here in the UK we get lots of even decimal stations Magic 105.495.8 capital fm106 sam fm
Why is the lowercase 'a' we type different to the 'α' I write by hand?
I write a in the type form. I always though it looked better when writing my name, now it's habit, people think it's weird.
I'm just a regular guy, not famous and nothing to hide. What could happen to someone like me not covering their webcam?
The absolute worst that could happen is that someone might be able to watch you go about your day. Of course, there are RATs that allow people to gain control of your entire computer, but covering your webcam won't deter that at all.
Why is Amsterdam such an important city?
Because it's the biggest city in the Netherlands .During the 17th century Amsterdam was one of the biggest and most influential cities in Europe. The Dutch East India Company had their headquarters in Amsterdam so it was home to a lot of merchants.Nowadays, Rotterdam is economically more important than Amsterdam, as the former is the biggest harbour in Europe, but because Amsterdam is the Dutch capital city and big, it still has a lot of company headquarters.Also, every tourist that visits the Netherlands comes to Amsterdam because of the canals and museums. And for the weed and prostitutes, of course.
how come people can't get sober on their own?
Can you elaborate more? Do you mean getting sober as in withstanding the drug's half-life until it's affects are no longer present, getting sober as in quitting the use of a drug entirely?
1Q84 by Haruki Murakami quote explanation
Its more of a poetical quote than a realistic one since it's in a novel , but I always interpreted this as something you can only understand by insight and not by hard reasoning. Like when children don't understand their parent's reasoning, but start to realize that they were right when they become older and change their viewpoint.
What are the arguments FOR the anti-vaxxers? I want to understand how people all over the world could possibly believe it?
I'm a 33 year old male who's never been vaccinated. I have 7 year old twins who I chose to vaccinate. I once thought that I never got sick due to the fact that I was never vaccinated . I'll admit I was apprehensive about vaccinating my kids but after reading every pro vaccine/anti-vaccine book I could find I decided vaccinating was best for them.
Why is it that there are so many people on reddit (not just visitors, but registered users), yet all top posts seem to plateau around 4 or 5K upvotes?
In my experience, I had [one submission] that rose to the top spot on the front page and over 5,000 karma within a couple hours of being submitted. Then as it stuck around the front page, more and more people began to down vote it and it until it was down to around 2,700 karma and fell off the front page. I assume Reddit has some kind of formula dealing with the ratio of up votes to down votes, where it keeps thing up until the ratio starts tipping more into the negative, with the age of the submission also being a factor. Because my post was pretty new, it stuck around the front page for a long time and really took a battering. I've had other submissions that took like ten hours to climb up to the front page, then stick around only briefly and leave with more of their karma intact.I got like 1,000 Karma for my post but got 500,000 views on imgur.Probably because a lot of people don't vote because once they see the post with 5K they realize their vote is meaningless, at least that's how I view it. Plus theirs such a large variety of things to vote on, so even the top posts don't receive everyone's votes because it's spread out.
Is there any particular reason popular radio stations seem to only play the same 10 songs over and over again?
There's software that predicts how much of a hit a song can be. If I recall correctly, among other things it measures sounds that produce alpha waves in our brains. it's predictions have an accuracy rate higher that 95%, can't recall but very close to a hundred. However, if the radio station doesn't play that potential super hit between songs that everyone knows and have listened to for years, it won't be a hit. People will change stations. That's what happened with Outkast's Hey ya. When it first aired, people would change stations. The people from the recording label knew it was a hit . So the stations started mixing the song with typical stuff you've listend to forever And it became a hit. If you want the specifics, I read it on a really good book called the [power of habit].I heard an interesting radio program about the song "HEY YEAH". basically, everyone in the industry thought it would be a hit on the radio. People liked it, but apparently customers would change channel when the song came on. The answer was to sandwich the song between Christina Aguilera and Celine Dion until listeners were comfortable enough for the "HEY YEAH" to lead. Once this happened the song exploded. Basically some radio stations may play most of the same songs over and over and introduce new song in between with hopes you don't switch channels for something you are more familiar withA lot of people in here are referencing "Top 40" but they're not telling you the top 40 of *what*. The answer is the billboard charts. You can find them at billboard's website. If you actually listen to a top 40 station and compare it to the top 40 on the billboard charts, you'll probably find that the top 15 get played the most, but that they do actually do a reasonable job of playing all 40 songs. Still, only 40 songs isn't many, which is why it seems so repetitive.
We carry 4k cameras around in our pockets. Why are television/movie studio cameras still massive?
Larger cameras are more powerful, durable and the sensors are of higher quality and more stable. Cell phone cameras and the like have tiny sensors that don't do so well quality wise when you bump up the power or temperature
How does Libertarianism come to terms with monopolies and polution
Ok, I'm no libertarian, but I've see two camps of thought for pollution: 1) The citizen's sue the polluter for violating their well-being. This runs into some obvious problems with the longevity of pollution, the non-immediate effects, proving who caused the pollution, and all those details. 2) Anyone who does anything to piss off anyone else has to worry about them hiring a hitman. Which will somehow keep everyone nice. As for Monopolies, nearly every libertarian I've talked to has claimed that the free market will keep monopolies from developing and that all instances of monopolistic behavior in the past was just and example of government interference.
Why does it feel so much better when someone else touches rather than you touching yourself?
When someone else touches you your body produces various hormones that give a pleasurable feeling. They aren't released when you touch yourself.
Why does the US have military bases and constant presence in other countries, but other countries don't have military bases in the US?
In various cases it was due to WW2. In other cases it's due to NATO obligations and basically the USA drops a lot of cash on the surrounding area .
What does it mean when my boss tells me that we can’t get paid more or offer more for new hires because of “fair market value”?
Basically it's the professional way of telling you that you're not worth it. If you don't like it they'll find someone who does
Why do they not put parachutes in commercial airplanes.
Regular people like myself, in the field of food service, know nothing of parachutes. That being said, if I misused a life saving device during an emergency, because of no knowledge and died, it'd open up the airline to potential liability beyond killing me in the first place. Cause lets be serious, if you're a regular guy on a crashing plane, ya fucked.Have you ever been on an airplane? There is barely enough room to put on a sweater, do you have any idea how long it would take to get 200 people to put on parachutes and exit the plane?There is no way how all passengers can be evacuated in seconds.Check out the crash flight videos, when the plane is crashing, it usually isn't flying level and it would have to evac all passengers like a military paratroopers drop in a very small window of time from when you Know the plane cannot recover. Edit* I should add, I think maybe evacuation pods may be more plausible, but again, it isnt like a ship where you have time between when the ship is doomed and when it sinks. Not even in military aircraft where there are ejection seats do the pilots always survive.Because "explain like I'm five" makes me first think how I would answer a five year-old, I would just say, "Because then flight attendants would have to take even longer going over safety features of the aircraft." I kid, I kidI thought you meant one big parachute for the whole plane. Those actually do exist for smaller planes.
How did aristocrats prove their identity back in time?
A great many of them were related to each other, including in different countries. They also socialized. At a court or castle you'd probably find someone who knew you. Also, class divisions were so sharp that just the way you spoke would proclaim your status, if not your identity.
Why does NASA not have manned missions to to the moon anymore?
It would be a waste of money and time. They have visited the moon already, a lot.They prefer to focus the time and resources on other projects, it's really as simple as that. Besides, isn't mars much more exciting?
How do insanely successful people manage to or so productive on only 3-4 hours of sleep?
I'm not insanely successful or whatnot, but I am in the military, and I've been on deployment and similar where the mission ends up taking most the day; 18+ hour workdays and such. Before I joined the military, I couldn't **imagine** working that much and getting 4 or so hours of sleep for months on end. After a while though, you just *do*, and your body stops begging for mercy and just submits to it. I'm not saying the military is like being a world class chef or a similar high pace job, but I can imagine its similar; you go into the 'gotta get shit done' mindset and your body goes along for the ride. Also, naps. Grabbing a nap whenever you can helps.
How can someone die if they commit suicide from jumping off a bridge since they land on water?
To be more precise than some of the answers here, the issue is with Surface tension. At high speeds, water is just as 'hard' to the body as cement, because the surface of the water can't get pushed out of the way fast enough to let you fall into the water without doing substantial damage to you.Follow up question: Hypthetical. If I decided to commit suicide by jumping off a bridge, then 1/2 way through I decided I didnt want to anymore, is there anything I could do to disrupt the surface tension below me enough to break my fall?Water acts a lot like a solid when you hit it very quickly. If you find yourself thrown out of a plane, it is better to head to the land rather than the sea. If you head for the land, you might hit a tree. If you hit the ocean, you will hit water.Water resists movement, like custard does. Imagine punching custard, your hand doesn't go very far into it, it seems solid. If you hit water at a high enough speed, it doesn't flow around you, but instead whacks you round the face like a block of concrete.Just think of when you do a belly flop, how much it hurts. It hurts because water doesnt move quickly and there is a force against you. Now imagine that from a bridge, your speed is too high and its like hitting the ground.
What is overclocking a computer and is it worth doing?
The clock on a computer drives the transistor switching and the signaling that goes down the wires . By upping the speed of the clock, you make these processes execute all the faster. As a result, given two computers where all things are equal, the one with the faster clock can get more work done. But, there are caveats. If you overclock your computer, you void the warranty. Further, there are specifications that dictate speeds and signaling, so that I, as an expansion card manufacturer, can make a component to a spec, and know it will work for every computer that complies with the spec. When you operate outside specification, you can introduce all sorts of errors. Most of the time, they are memory errors - often, either the memory components don't have the time to set to a value, or the signal takes too long to go down the bus before the next clock tick, or electrical noise can just screw shit up. Sometimes, it's a transistor that can't flip on or off fast enough, though, my EE friends tell me thats rare these days for a number of reasons. If you're playing a video game and you are incurring error from overclocking, who cares? You probably won't even notice. If you're performing computation for some simulation, a PhD. thesis, or perhaps your finances, why risk incurring an error that can compound in your data? I'm just saying, sometimes, error is irrelevant, sometimes, it's not worth the risk. Side effects of overclocking is heat, usually because you have to up the voltage. These things can cause thermal damage or shorting - basically, you risk damaging components or at the very least you're reducing their expected lifespan.
Are historical events recorded in the time zone that they occur? Wouldn't an event that occurs in the United States given the right time occur on a different day in for example Australia?
The end of WW2 in Europe is celebrated on the 8th. But in Russia it's celebrated on the 9th, because it was after midnight Moscow time when the capitulation paperwork was signed.An example of that is first step on the moon by N. Armstrong: US people learn it happened on July 20th 1969. In France, where I was raised, we learn it happened on july 21st 1969, at 3:56 am.
Why does the man tend to have to pay the woman in the event of a divorce? And what are the payments going toward?
Traditionally, the husband worked outside the home, making money, and the wife worked inside the home, taking care of the children and the home, cooking, and suchlike. In the event of a divorce, both the man and the woman would need money. The man--who had spent his life advancing his career--would be in much better shape than the woman, who would have to get an entry-level job. Thus, basic fairness meant that the wife got payments in the event of a divorce. And, since the wife's work was what let the husband spend so much time on the job, his earnings were seen as partly the result of her work, and thus partly belonging to her. Things are more complicated now, but the basic idea is still there.
Although we use our dominant hand/arm/legs for 90% of tasks, our muscle definition seems to develop evenly on both sides. Why is this?
I don't know that it does really. Anyway, most of what I do with my legs is walking so they'll be pretty even. Most of what I do with my hands is typing so they'll be pretty even. My dominant arm is very slightly more defined because I carry my laptop bag on that side most of the time.
why Watchmen is considered the greatest comic (graphic novel) of all time?
I think the best way to find out is by reading the comic itself. It's not long, only 12 issues, and you'll enjoy yourself.
Why are certain paintings worth millions even though they might look less appealing to the average person than a $50 painting might?
Things are only worth what people are willing to pay for them. People are willing to pay millions for art, and therefore it is worth millions. There is no person or company that sets the price of goods in this world. Consumers set the price of everything. Likewise, apple doesn't decide how much an iPhone or iMac is worth. They decide how much they think people are willing to pay for it. Then they set the price there. As for art, its all 1 of a kind. Therefore the worth of that art becomes whatever the consumer decides it's worth to them. If there was only 1 iphone ever produced. Imagine how much it would sell for.
Why do the wives in animated sitcoms often have unusual voices?
Most male comedy writers don't know how to make women say funny things, so they just make them say things funny.
How and why pilots use oxygen when going at high speeds
Just to add on a lot of fighter jets are pressurized and can be flown without masks. The masks are to provide air in the event that the canopy be shot or fractured somehow .
If bad taste is our body's auto-defence against bad/unhealthy food (eg. poisonous/rotten), why does junk food taste so good?
Through most of our history, salt, sugar, and fat were rare. They are very satisfying because they signal our body that we're getting rare nutrients. Now salt, fat, and sugar are everywhere and food manufacturers have learned how to make food so rewarding that we crave more of it.Sugar. Sugar was really really difficult to get. Folks graved sugar. Junk food tastes good because of salt and sugar - and other addictive shit. If you must, chicken wrap.
If the US Government raises the minimum wage, who will absorb the extra costs?
Because your post isn't asking a simplified conceptual explanation, but rather for an answer, its been removed. You should try /r/answers, /r/askreddit or even one of the more specialized answers subreddits like /r/askhistorians, /r/askscience or others too numerous and varied to mention. Rest assured this doesn't make your question *bad*, it just makes it more appropriate for another subreddit. Good luck!
Why isn't more software made to run on Macs?
To make stuff run on Macs requires some additional programming and the market share is small enough that it doesn't warrant the additional expense.
How are we able to read and understand languages (like hieroglyphics)?
◊" means "plants" and so on. Ultimately we learn enough words to decode the original meteorite, as well as gain insight into how the mystery language is constructed, and can make assumptions about new words not in the diary entry . , there's nothing written in both the unknown language and a known language, so that we have a piece of writing with nothing to compare it to. And then we 've got no idea where to even begin, and perhaps never will.)
Why do US based airlines lag behind in service and quality, especially in their premium cabins?
Answer is already in the thread elsewhere - capitalism. Came here to say Singapore Air sucks ass in my experience. Fine if you're a rich dude, terrible if you're anything else. Wife and I flew to New Zealand from the UK with them for our honeymoon. Spent our savings on an upgrade to economy plus - why not, you only get one honeymoon right? And it's a 28 hour flight. Treated like shit from start to finish. Wife was ignored by all stewardesses , both of us generally overlooked for drinks, my entertainment system didn't work and they didn't care, sat on the plane watching them turn the flight around at a short layover, they reused pillows and blankets, the list goes on. Changed to New Zealand air for the final stretch, that shit was the bomb. And their safety video features the all-blacks doing a rendition of the men in black theme with safety related lyrics.
Why are there literally millions of porn movies on the internet for completely free viewing, but so few regular movies?
Pornhub, youporn, redtube, and most other main porn websites are all owned by the same company, MindGeek, that owns major porn production cimpanies such as Babes, Brazzers, etc. It is basically a monopoly of producers and distributors, which means that the movies are uploaded directly as they are produced, since the views end up as revenue for the company either way. Many others producers also upload incomplete videos to these websites in hopes of attracting premium customers. it's the equivalent of handing out movie trailers to cinemas, but the trailers themselves are usually enough to satisfy most viewers. Since they can't stream in cinemas and the rental industry doesn't pay ad well, the production of online videos is prominent in the industry; that also makes it easier to pirate, and it is difficult to win lawsuits against a large company such as mindgeek so I doubt people would try. You also have a steady production of free videos like amateur porn. You can find many regular movies online for free, it's just that they are lower quality or not protected by copyright. The movies that are nkt readily available are the ones produced by huge distributors, who make their money off official sales in cinema and dvd stores. Also, With porn, the demand for higher quality is lower, and the production process is easier so there are a lot more movies being produced on a regular basis. You could probably make 100 movies in the time it takes to plan out and film a blockbuster, no bureaucracy to stop the process in its tracks, and the budget is minimal.
Creationists using the 2nd law of thermodynamics to try and disprove evolution.
On a side note, those are some pretty fucking stupid questions. I'd even say I'm religious and I just can't like what . ugh. It's embarrassing. My favorite was > How do you explain a sunset if *their* is no God? How ignorant can you be? Listen to the *facts* people, it doesn't mean you cannot be religious too.
What is happening when something gets "sun bleached"?
The sun's radiation breaks down the molecules that make up the paint or dye. They break down into different molecules that reflect the light differently. That's why things change colour in the sun - sometimes they don't even turn white, they just turn a different colour, because the pigments have been broken down into different substances.
On 9/11, why did schools all turn their TVs on and force kids to watch the footage when we don't do this for any other disaster/catastrophe that occurs? Why was this so common?
You're probably too young to remember when JFK was assassinated, but from what I remember at my school, televisions were wheeled into classrooms or the gym and students and teachers stood and watched the news as it unfolded. Noted, this was a small school in Ohio -- I have no idea how the Dallas schools handled it. On the other hand, the assassination of a president or presidential candidate is a fairly short piece of drama. The Sept. 11 attack was not short at all. There was the first plane crash, there was the second crash , the attack on the Pentagon, the plane crash in Pennsylvania, the towers aflame, the towers coming down all aircraft grounded, cell phone towers down, all transportation into and out of NYC stopped, rescue people from all over the area sent to the disaster site, people searching for missing family members or friends frantic parents, people stopping to watch the news in store windows, in bars I was working for a suburban NYC newspaper at the time and was allowed to sit in a high school civics classroom as the day progressed -- from what I recall, each of the area's schools chose how to handle the news and it varied from school to school and administrator to administrator. What happened in the elementary schools was different from what the middle and high schools were doing. From spending more than a decade working with public, private and religious schools, I can guarantee that there is no one overriding rule or decision that all American schools subscribe to. What you recall was probably true for your school but not for others.
Why is the standard dose of just about all medicines two tablets? Couldn't they just make one that's twice as concentrated?
But what if you needed to give a smaller dose to someone who was physically smaller, or whose body was weaker and couldn't handle a standard dose? A twice as concentrated dose would make it easier for most people, but impossible for other uses.
ELI5: If "yellow" colored urine is a sign of dehydration, why does the body get rid of that liquid instead of using it to hydrate me?
Because your body isn't *that* efficient at processing water. You aren't a camel. And what's in the urine is more important to get out of your body than keeping that amount of water in is.
Why do people pray for things if "God has a plan?"
It is said that prayer moves mountains, my takeaway has been that the mountain shall only move if God intended it to be moved. I also believe that it will not be moved if it is not prayed for. I believe this is because we are supposed to show our love of God, and this would be a way to show that love. I don't really have the answer where the omnipotent God needs such things for reassurance or whatever it is, but for me part is tied to our free will.
Why don't monkeys utilize inferior animals? Why do monkeys not ride goats around?
Evolution isn't a linear progression, there are no such things as 'superior' animals, all animals are superior for their respective niches and environments.
Why do high high court government positions (President, Supreme Court Justices, and etc) get sworn in on a bible when we have separation of church and state?
It's just a symbol. They are affirming an oath. They could do it on any holy book, or any comic book for that matter. It's just no politician is going to swear an oath on a Green Lantern comic. The same is true in court. Bibles are not required there either.Because the separation of church and state don't mean that religion and government have nothing to do with each other. It just means that no single religion has power within the government. Bibles are used because they are the default. Teddy Roosevelt didn't use one, John Quincy Adams swore his oath on a book of law, Lyndon B Johnson was sworn in using a Roman Catholic Missal. It's not that the government is conceding power to religion, it's that they are swearing that oath in the same way that they follow their faith. Theoretically you could be sworn in on any relevant document, there's no law requiring the use of any specific object, or even that you say "So help me God". In theory you could be sworn in on any book that represented a dedication to a set of ideals and/or beliefs and request assistance from any person or power. You could be sworn in with a law textbook and say "So help me Congress" if you so choseWhen you are sworn in you have your choice of any religious text, the constitution, or nothing at all. It is symbolic and since most people are religious it gives added weight to the oath taken. Separation of Church and State means that the government cannot set a specific religion as the state religion and require people to practice it, and it cannot prevent citizens from practicing a religion. This includes preventing members of the government from practicing their religion or using their religious views to influence their jobs and choices which in turn includes choosing to swear an oath in a religious fashion.
Why is it legal for members of the paparazzi to harass celebrities and sell photos of them without consent?
Photography in a public place is a protected right. If it were made illegal, the negative ramifications would be extreme. However, there should be better laws against harassment by the paparazzi . It's not illegal to sell your photos to whomever you wish, as long as the photos were legally taken and are yours to sell. What the buyer plans to do with the photos has nothing to do with the transaction. Tabloids get away with outlandish claims because they are considered satire, just like The Onion and other satire news websites can publish any ludicrous story they want, because the general public knows they aren't real stories. The problems only arise when ignorant people mistake those sources for real information.Note that Paparazzi can not take pictures while a celebrity is behind their fence or in their gated community. Photos are only allowed on public property. They cant take a picture leaning over the celebs property ya know?
The differences between a teaser, a teaser trailer, and an official trailer for a movie.
The one thing you need to know is that there are no official definitions of those terms. They're used very freely by consumers and marketers alike. They're almost interchangeable with one another however there are patterns that tend to appear in each. A teaser can range anywhere from 10 seconds to 2 minutes. It usually shows very limited plot information and mostly showcases the design, aesthetic, title, and release date of the film. These are released several months to a year before the film is released. A teaser trailer can be synonymous with a teaser. Generally, a teaser trailer is slightly longer and might give away a few more plot points. An official trailer is the final and main trailer for the film, usually 2-4 minutes long and released within 3-4 months of the films release date. This gives away the most plot details out of all the teasers/trailers and is shown before other movies at the theater.
Why does paper not burn when put in the microwave?
First of all, paper is dry so it doesn't get heated by a microwave. Second of all it would take quite some time for a microwave to generate enough heat to ignite paper even if it was wet.Because paper has very little water in it and microwaves work by exciting water molecules.
The concept of slipstreaming in racing
It's easier to imagine in water. Imagine you had someone running in water. They are expending a lot of energy to push it out of the way and is leaving a churning behind them. If you were to run in the churn behind them, you could go the same speed without working as hard. At higher speeds, air works the same way.
Why do people say IQ tests (new ones) are biased???
They test for a narrow range of intelligence and don't address the concept of multiple intelligences or that the lens through which the test is portrayed might have a bearing on one's score.
how do we fall asleep?
Lots of ELI5 posts lately which clearly don't belong here. This post is obviously better suited for /r/askscience
Why does the U.S. say "Merry Christmas" and the U.K. say "Happy Christmas," and when did this distinction appear?
I think you'll find Merry Christmas is used more than Happy Christmas in the UK and commonwealth nations. Maybe Happy Christmas just isn't used at all inn the US?", 'In UK we tend to say Merry Christmas which leaves you free to wish a Happy New Year. If you Happy Christmas it leaves you nowhere to goI moved to Australia eleven years ago, and had to learn to say "How are you going?" instead of "How is it going?" or "How are you doing?"Are we overlooking the obvious here? If you say "Merry Christmas!" you can finish with "And a happy New Year!", but if you say "Happy Christmas" you're going to look like an idiot when you also start the next sentence with "Happy".I'm British and I'll be in the cold dead ground before I accept Happy Christmas. It's Corporations trying to be politically correct because they don't want to imply alcohol.
Why, even though New York and Spain are approximately 40° latitudinal, do they have vastly different climates?
Spain is actually a very complicated country. In the Northern Atlantic facing Cantabrian strip of Spain, it's influenced by the North Atlantic current funneling warm moisture from the Florida waters up to the British Isles. This area of Spain has climate just like Ireland, Wales, England, and the French Atlantic coast. This small strip ends at the Cordillera Cantábrica, a mountain range that span northern Spain. The mountains basically present a wall to the Atlantic moisture and divides the rest of the country in terms of climate. South of the mountain range is either a continental Mediterranean climate for the Castille-Leon plains or a coastal Mediterranean climate at the coast. Both of these regions have a summer high pressure cells that prevent rains from pushing into the region in the summer. In the winter, the jet stream overwhelms the high pressure cells and brings moisture for precipitation. However, it is much more likely to snow in the high plains than in the southern coastal cities. New York is subject to flow of the jet stream and there are large fluctuations. Sometimes, it reaches rather far south in the Gulf of Mexico area. Sometimes, it gives New York a blast of Arctic air. The weather patterns are unpredictable and it gets even more unpredictable as you move east towards Boston. In the winter, the region has a curious weather pattern called a Nor'easter in which warm storm systems originating from the gulf hit cold water and forms a cold-core cyclone just offshore. hmmm . that wasn't a very good ELI5
Why is push-back from power utilities against solar power such a big deal?
First, it's a benefit to the consumer to sell back to the utility. They DO use solar when they can, and buy from the utility when they cannot. But they also get a credit if they generate too much solar at any given point. The buy-back rules were put in place to incentivize people to add more solar panels. Honestly, it's not a big deal. As solar becomes cheaper, more efficient, and more prolific, the rules about buy-back will be cut back or removed, because they won't serve a purpose. Regulatory bodies won't allow utilities to die, because they do need the infrastructure in place.
Why do I want to hold my penis while falling asleep/sleeping?
I'm not sure.. But I cup my vagina or have a hand on a boob quite often. It's just comforting.
Glasses and visual aids in general are a fairly recent invention. How did people with eye problems manage anything before then?
Most people with impaired vision are not impaired to the point that they couldn't survive without glasses if they had to. One of the big thing people need glasses for is to read small text close by. For most of human history, this would not have been an issue. Not being able to see clearly at long distances is unpleasant, but you could easily survive without aid. Or not being able to focus clearly on an object is again inconvenient, but not destructive.
How does legalizing a drug lower it's usage?
* people are more likely to seek treatment for addiction* people are less likely to wreck their lives with the cost and legal consequences of drugs, which in turn gives them less reason to use drugs* drugs become more reliable, potent, and available, so people don't feel the need to gorge themselves when they can* people who want to be self destructive and rebellious move on to something else* it becomes easier to regulate drugs and keep them out of the hands of the underaged where there isn't an illegal dealer on every corner
when looking up a song on youtube on my phone, why do all the results end up only being live versions?
It's been a while since I took a class on the music business, but I think it's cause Youtube needs separate licenses for the performance of both the song and the master , plus separate licenses on top of that for mobile devices as opposed to computers. So to allow live versions they just need to pay off the performance rights organizations , but not the record company/owners of the particular recording. Again, it's been a while, so trust this response at your own risk TL;DR it's cheaper for Youtube
Why does the UFC still use PPV?
It's because the PPV broadcasters put the most money upfront. We have a similar situation here in the UK, where Champions League football is on a pay network. The result is viewing has fallen from millions to thousands, but the broadcaster offered the most money. As long as significant numbers pay for TV services they will swallow up big sports to attract customers. For the reasons you highlight, though, I can see a day when Amazon, Google, Netflix or Facebook buys them and breaks the existing model.
Can you detonate a bullet with blunt force?
> can you hit it hard enough to make it fire? This would be much easier with a rimfire cartridge as centerfire would have the primer more protected in the center of the back of the cartridge. Whacking it hard enough should dent it and set off the round. Keep in mind that as it isn't contained in a firearm barrel it would probably just explode, throwing small amounts of casing shrapnel around.
On a coin toss how is the chance of getting Heads still 50% even after getting 4 Heads in the previous tosses.
Think about a much simpler version of the same problem. Let's say you toss a coin twice. On average you will get 1 head and 1 tail. After you get a tail on the first toss, what are the odds of getting a head on the second toss? By the logic you are stating, then the odds would be 100% that the next toss was a head , but that obviously makes no sense, as their is no system to force the coin flip to be a head. In fact the odds of getting a head or a tail is 50%, just like it always is. So what's actually happening in this case? Think about it this way. Before you flip the coins there are only 4 outcomes that can happen. Those are HT , TH, HH, and TT. Each of those are equally likely , but two of the 4 choices end up with a head and a tail so there is a 50% chance that you end up with 1 head and 1 tail, and that's the most likely event . Once you've flipped the first coin what you've actually done is learned something. You've learned that the first flip must be a tail, so you can remove all possibilities where the first flip isn't a tail . At this point there are only two options, so there is a 50% chance of TT and a 50% chance of TH. Basically every flip of the coin removes half of all possible scenarios you had before you started flipping, and the odds of every event changes with each flip. This continues until you get down to the final flip , after which you are down to 1 outcome .
Why do some people function better in the morning and other function better at night?
_URL_0_This video might help, it's mainly pre-determined in our genes. From an evolutionary point, it would be an advantage to have different sleep patterns to offer protection in a group during the day and night.
Why are CGI effects so expensive to produce, when they are a virtual tool, that seemingly only requires software?
There's two big costs involved with CGI. First, you've got to pay the artists. It takes time to apply CGI and get it to look right. Often it has to be done frame by frame. It's a lot like painting--having the right paints and brushes does not get you anywhere near the finished product. Taking up many hours of many skilled artists' time is going to be expensive. Second, CGI rendering takes lots and lots of processing power and time. All of the changes made to the video need to be rendered into final, full-quality frames. Film studios rent time on powerful computers to do this, and feature films can take weeks of non-stop rendering before they're done. Since this hardware is so expensive, renting time on it is expensive, too.
Teeth grinding at night and how it can be so loud. Also how can our jaws clench that hard unconsciously but not awake?
My girlfriend does this. She uses a mouth guard but half the time she takes it out in the middle of the night. Then cuddles next to me and starts grinding away. I don't know what to do I love her but I cannot sleep next when she does this.When you are conscious, there are protective mechanisms that stop you from biting too hard. When you are asleep, these mechanisms are no longer present so people who grind will grind at a much much higher level than they could if they are conscious.
How do all political cartoonists have the same art style and handwriting?
I remember reading that the art style to depic a satire of a figure of power started in the french revolution . And that sort of style, exaggerating the person face and body, as well as framing them in a white background is something globally done to parody politicians or political ideas.
Why does the Gambler's Fallacy hold true?
when it comes to a random act like flipping a coin, past results are no indicator of future success. that's why it's random.
Why do so many modern adults have poor spelling/grammar?
Something you should consider is that most people will only develop skills to the extent they are needed. Most people don't need proper grammar and spelling to make their living, so they don't go out and try to learn much more. If you really analyzed your own grammar from the perspective of a English professor, you would probably see that you are making quite a few mistakes yourself. Maybe for you it was necessary or rewarding to reach the level you're at, but if another person can articulate themselves for their needs without spelling correctly or understanding the difference of your and you're, why do you care? There are plenty of small mistakes people make daily.
If memory and bandwidth is getting cheaper and cheaper, why have ISPs started capping data more and more?
> why have ISPs started capping data more and more? They want to charge you more money. If you go over the cap, they get to slap you with an extra fee. That's about 80% of it. The other 20% is that fast internet lines are expensive and they don't want to pay to upgrade their lines to faster ones just so everyone can watch 1080p streaming sheep-pr0n.
