Why don't people seeking physician-assisted suicide just overdose on their regularly prescribed pain medication?
|
I think you're missing the point. Any one can kill themselves any number of ways. The only limit to the number of ways you can off yourself is your imagination. What is up for debate here is whether a person has the right to kill themselves by being assisted by a physician. A physician can give a cocktail of drugs that will make the suicide both quick and painless, while providing the oversight that makes sure both of those conditions happen.

What were the evolutionary benefits (if any) to humans enjoying certain "music" or having some sounds appeal to them.
|
You're assuming that the enjoyment of music is the purpose of an evolutionary advantageous skill, but it's actually probably just one applications of an evolutionary advantageous skill. The skill is *pattern recognition*. Early agriculture was made possible by our ability to recognize patterns. Our ability to hunt specific species is dependent upon our ability to recognize a pattern of behaviour. Our ability to learn to read and speak a language is dependent on our ability to recognize patterns. etc. Bear in mind evolution *doesn't* fine-tune organisms and traits for specific needs and purposes, and oftentimes certain evolutionary traits are favoured because they are advantageous in specific situations but can be useless or downright ridiculous in other situations.

Why the OJ Simpson case was such a big deal?
|
It was a big deal because it was obvious that he murdered his wife and his wife's friend. Anyone who followed the trial could see that fact clearly. The fact that he was acquitted does not assuage his guilt.OJ was a huge celebrity He was a great football player then turned actor, and spokesman. He was a household name and was a very marketable and handsome guy. Then he killed two people and got away with it even after DNA found in his house, shoes, glove etc His defense turned it into a racial case and it went south for the prosecution. Now everyone hates him.

Why the population of Bangladesh, Pakistan, India and China so high compared to other nataions in this world
|
Rice, rice, baby. Of grains available to the pre-industrial world, rice yields the most calories per acre of land. At the same time, it is labor intensive, and requires more people to farm it. You wind up with a staple that both supports and requires more people, and that leads to a higher population densityExtremely fertile lands. India has the largest amount of arable land in the world, just behind the US. Include Pakistan and Bangladesh in it, and you got a region with the most amount of arable land in the worldThat region of the world has had a large population for a long time. Until the 1700s it was the richest and most advanced region in the world. It has many large rivers that created a fertile area for people to settle in.

Why do most people get nauseous when reading in the car?
|
It is generally caused by a discrepancy between the motion being reported by your inner ear and the motion observed by your eyes. As the car moves, your inner ear is constantly aware of the movement. Whilst reading, your eyes are mostly seeing a static image, the book. The fact that the two don't add up and give similar feedback causes the brain to assume there is a problem, potentially due to something you have eaten, which can lead to it deciding that emptying your stomach is the safest option overall so as to prevent possible poisoning", 'Better yet, how do people read in a moving car without getting nauseous?

Why does drinking alcohol "burn," and what makes some liquors "smoother" than others?
|
From Google: Alcohol, especially in high concentrations, will irritate the oral mucosa . That irritation can come across as a burning sensation, the same kind of thing that happens with capsaicin . Alcohol’s also a solvent, absorbing some of the moisture from that mucosa and causing a drying sensation that can also present itself as a burning feeling. But that only covers the mouth and throat—the heat that spikes the roof of your mouth and back of your gullet as some bourbon slips down into the esophagus. What about the warm feeling that graces your stomach once the alcohol makes its way down? That has to do with blood vessel dilation. Alcohol, in moderation, can dilate blood vessels . Dilated blood vessels impart a temporary feeling of warmth. And from another ELI5: When spirits are distilled, the liquid comes out in 3 parts, heads first, then the heart, then the tails. The heads and tails contain lots of nasty things such as fusel oils. The best spirits / top shelf producers only take a small part of the heart which contains the cleanest spirit. This means less hangover/bad shit in your body. The quality of the raw ingredients and distillation equipment/methods also contribute significantly to the end products quality.Also, if a spirit is aged for a long time in wooden barrels, this process rounds off the harshness that may be found in unaged spirits. This also imparts some of the qualities of the wood such as vanilla flavours/woodiness. It can also however add hangover-causing congeners due to the chemical relationship between wood and alcohol.[Why does alcohol burn when your drink it?] **tl;dw:** Ethanol makes the VR1 receptors in your body more sensitive and lowers the threshold of detecting hot stuff from 42°C to 34°C . As your body temperature is usually about 37°C , **you're basically just feeling the heat of your own body**.

does plugging my ears with earplugs do any damage to my ears?

No, soft foam earplugs can cause no damage unless you leave them in for days at a time or somehow manage to stick them in far enough to hit your eardrum. This should be next to impossible though.

why is pointing at something considered rude?
|
Cultural norms vary, but as I understand it, pointing at "things" isn't rude and is often necessary to communicate clearly. However many people consider pointing at another person aggressive and therefore rude if the situation doesn't warrant an aggressive reaction. It may also be considered rude if you point in response to a question or statement but in those cases it's the lack of verbal response that's actually the rude action. If someone asks you a question you are expected to verbally respond in kind so silence often offensive.Put yourself on the other side of it. You're walking down the street, and you see someone across the block pointing at you. Why are they pointing, did I do something? Is there something wrong? What's going on?

How does a heat seeking missile work?
|
First attempt at ELI5. an aircraft engine and fuselage all generate heat. This radiates away from the aircraft in the Infra Red spectrum of light. Humans obviously cannot see this mostly, but IR cameras can. By using some smart tech to determine shape and the front or rear of an aircraft by interpreting an infra red picture captured by the IR camera in the nose of the missile, the missile adjusts its path to hit the source of the IR energy. Thus flares counter these missiles by blinding and seducing the missile with a large heat signature, unfortunately smart people have begun programming missiles with some brains and they can tell the different between flares and the aircraft or tankYeah and an image processor behind that.. Google heat seeking missile images there are a few pics .. These images can be transmitted back to a command centre from the missile

to someone who doesnt live in America BlackFriday? is it really that good?
|
Black Friday is the way the American population "kicks off" their Holiday shopping season. Lots of stores open at Midnight and stay open all day, most if not all stores have really good sales that make staying up that late tempting. It's good in some ways if you are looking for something specific, I have a friend who got an XBOX and Kinnect bundle cheap. But some people act like lunatics and will hurt you to get what they want;like it's a free for all. It's totally something everyone should experience once in their lifetime.is it really that good? sometimes. it really depends on what you're buying. a price cut on something expensive like a tv or something is helpful, but as expected, this is america: we're overly competitive, we exaggerate things, and sometimes we just enjoy a good old fashioned ruckus.

Why do some companies copyright strike Youtubers for putting their logo/product/song in their videos?
|
That's not how copyright works. Copyright is fundamentally the right to require people to ask permission before they do anything with your work . As with all these things, failure to defend this right in any particular instance harms your ability to defend it in general. When you played that song on YouTube, two relevant things happened. Firstly the song was overlaid on the video without anyone asking permission . Secondly, you listened to the music without permission . Copyright law doesn't care if a particular breach is financially beneficial for the musician or not. To be honest that'd be a terrifically complex thing to judge. Imagine if the musician could sue YouTube for every video play that didn't result in a purchase of the song but couldn't sue YouTube for any video play like yours because it resulted in a sale. How would you enforce that? Or imagine if the musician couldn't sue for a particular video if it resulted in more sales than would have occurred without the video. How would you measure that? Or, imagine you make videos. What if the law said that you could use any music you liked without permission provided it generated at least 100 additional sales, but if it only generates 99 sales you can be sued into the stone age. Would that be a good system? And how accurately could you measure the sales your video generated? Instead the law creates a much simpler system. You ask permission first. If the musician thinks your video will be good advertising or otherwise beneficial, great. After permission is given, nobody is going to argue the toss.

In 2008 oil was "running out" and the price of a barrel of oil sky rocketed. Fast-forward seven years and there's a surplus?
|
A couple things happened. First, fracking allowed access to oil that was previously economically unviable to extract. But with the high oil prices and refined techniques and equipment, it eventually became viable. With the increase in supply, the price started to drop. OPEC countries were expected to lower their supply to control the price, but they don't really trust each other to actually do so, so none of them have significantly changed their production. So with extra supply and not a similar amount of rising demand, the price has dropped significantly. It's already more expensive to use fracking now than the oil the process produces is worth, so it's expected to slow down in the future. But should the price of oil climb up again, the equipment and processes is already there to start it back up again.

Why do retailers purposely damage/break their unsold items before throw it to the garbage? Why don't they donate it instead?
|
Two part answer: 1. Retailers break things to discourage dumpster diving. If you knew that Best Buy was going to throw out all their electronics, you would see lines behind Best Buys to go through their trash. Obviously, people don't like it when other go through their trash. 2. Donating certain things is just counteractive. While some places like Panera do donate their unsold food, it's never to individuals, but to charities . Food is usually okay as it's a necessity and not a big ticket item. But if Best Buy were allowed to donate a $1500 TV to someone for no reason, that system can be abused to commit tax fraud.

Why does my mechanical watch say not to adjust it between 9pm and 4am?

On a lot of watches, the date pinions start engaging around 9pm and fully disengage around 4am. If you adjust the time or date during that time, you run the risk of damaging the mechanism .

How do modders optimize games that are badly ported?
|
There are several ways. The easiest is probably to just twiddle with the config files until the game runs better. More complicated issues, such as framerate limits that normally can't be disabled, can sometimes be fixed by editing some parts of the game's executable file or other binary files with an hex editor. When that isn't enough, programs can be created that attach themselves to the running game and modify, replace or intercept some parts of the program code . With enough time and dedication, entire frameworks with plugin systems can be created that way that can change a game in almost every imaginable way, which includes fixing porting issues. Obviously, there are serious limits when it comes to online multiplayer games, since the more advanced methods are also used for cheating and usually result in bans when detected by the game's anti-cheat mechanism.

How does space-time dilation work?
|
I forget what redditor explained it this way to me, but this is the best way I can describe it: Think of space and time being orthogonal. That is, they are set perpendicular to one another, like X and Y are on a graph. Taken together, they are space-time. You are always moving through space-time at speed *c* . If you are at rest in your movement through space, then you are moving forward through time normally. The faster you go through space, the slower you go through time. If you are moving through space at *c*, then you are not moving through time at all. A photon released from a light bulb or star does not experience any passage of time before arriving at its destination.

At what point is being a porn star different from prostitution?
|
For starters, it isn't completely clear that making pornography is legal in most US jurisdictions. In the absence of a law or legal precedence explicitly saying one way or another, it is entirely possible a pornography producer could be convicted under prostitution laws. Most state courts haven't said one way or another. That's why most of the pornography production in the US comes form a single state, California. In the 1980's, producer Harold Freeman hired actors for a movie called Caught from Behind: Part II, and those actors explicitly performed all the standard sex acts. As a result, Freeman was charged with pandering, or providing prostitutes to customers. Freeman was convicted and eventually appealed all the way to the California Supreme Court, in the landmark *People v. Freeman 46 Cal 3d 419 *. The court ruled in Freeman's favor, saying prostitution means someone is paid to have sex primarily for the purpose of direct sexual gratification. Being paid to have sex for other purposes is not prostitution, and making a dirty movie is a valid and legal purpose. The prosecution chose not to appeal to the federal level, so this ruling only applies to California. However, it has been used as an indirect precedent, as in *New Hampshire v. Theriault, No. 2007-601 *. Does this mean prostitution is legal so long as I film it? Sorry, no such luck. Just because you can manufacture some contrived explanation that would make your actions technically legal, a jury still has to buy that is what you were actually doing. If you set out to pay someone to have sex with you because you wanted someone to have sex with you, propping up your cell phone the night stand of a cheap motel isn't going to change that.

Why do planes shake when going through clouds?
|
Usually it's cumuliform clouds that do this. While enough moisture in the air will cause clouds to form, any source of lifting will cause these clouds to fluff up. That air movement will, obviously, also effect the airplane and push it around. It's basically the same as turbulence you get in clear air. The lifting can be thermals , orographic lift , or just convection as different air temperatures mix around . Any movement of air will move the plane around the same way it moves the air. Pay attention next time you fly through a thin little cloud , there will probably be very minimal, if any, turbulence .Clouds are thick groupings of moisture causing more resistance against anything moving through it. So when you're flying through "clear" skies there isnt a whole lot of 'stuff\' in the way of the plane.

Why do we find stuff "oddly satisfying?"
|
The human brain responds to and rewards you for identifying patterns. An example of this is music, where your brain rewards you for predicting and identifying patterns of notes. This is why hearing familiar music is satisfying, while music you never listen to sounds like trash. You can also find patterns in paintings and other artwork. A lot of Renaissance painters implemented concepts like the Fibonaci sequence, the Golden Ratio, and symmetry because they believed these patterns were naturally pleasing to the human eye. These patterns are also frequently seen in nature, and it's believed the human brain unconsciously rewards you for identifying these patterns from nature. The brain also rewards you for identifying breaks in patterns. Take the subreddit /r/mildlyinteresting . Why does looking at a mundane yet slightly interesting picture feel "oddly satisfying?" Because the picture shows something that ever so slightly deviates from the norm, and your brain gives you a reward for understanding that break in the norm.Great question. To my knowledge there is no science on oddly satisfying videos and why we find them so enjoyable. However, it probably stems from human's liking symmetry so much. There have been studies where humans find the face that is symmetrical more attractive than the one that is not. A lot of oddly satisfying videos feature some form of symmetry or neatness that is appealing to the human brain.

Why do you get extremely hot right before freezing to death?
|
When you are cold, the blood vessels near the surface of your body constrict, reducing the amount of warm blood exposed to the cold and limiting heat loss. Your body can only keep that up for so long, and when it finally gives up, the warm blood comes rushing back to the skin, giving the illusion of being too hotThis was an article I read a couple of years ago that explains it very well: _URL_0_

Why do Macs seem to run games way worse than PC even if they aren't games with crazy graphics?

What specifically have you experienced?", 'Optimizations. Even if you have a "hackintosh" it'll run bad. Everyone uses windows so nobody makes a good port for mac. Just another reason to get a PC.

When we really have to pee, why does walking or moving lessen the need "to go" in the moment?
|
Needing to urinate is something which can be suppressed by the sympathetic nervous system activity, or becomes more obvious when parasympathetic nervous system activity predominates. Exercising shifts the balance towards the sympathetic nervous systemSeems like this could possibly be related to gate control theory: your body/nerves have trouble processing more than one type of stimulus, so a neutral stimulus occupies the "gate" and prevents noxious stimuli from reaching your brain.While we're on the subject, why is it that I can make it home having to pee but the second I get to the house I have to do the pee pee dance while I unlock the door?", '> Doing the “potty dance” helps alleviate the urge to urinate. > plausible > For a control test, Grant, Tori, and Kari began with empty bladders and each person drank 2 liters of water. They continued their normal daily activity and measured how long they could wait before urinating. Tory was able to last 1 hr 57 min; Grant, 1 hr 58 min; and Kari, 2 hr 40 min. > They repeated the procedure the next day, but this time attempted to dance and move around to help them combat the urge to pee. In this test, Tory lasted 1:31, Grant 1:51, and Kari 2:47. > On the third day, the procedure was again repeated and this time each person attempted to relax as much as possible both physically and mentally. Tory lasted 2:05, Grant 2:46, and Kari 2:43. > After noting that the results of each method can vary widely from person to person, the team called this myth plausible. [Mythbusters]

What exactly is Effective Demand?
|
There *was* no mention of a constrained market in Econ 101, because it's a complicated concept; this is why you should ignore everyone who tells you that they know what economic policies we should have because they took Econ 101. Anyway. Suppose that I want buy a smoothie every time I go to work out. My demand for smoothies then depends not just on the price of smoothies, but the price of the *gym* as well. If the gym is too expensive, I won't go, and therefore I won't want any smoothies at all. So my *effective* demand is then 0 , even if my *notional* demand is very high .

Why does fresh cut grass smell so potent?
|
Because it's traumatized! Grass release chemicals when they are cut or injured that do a few things. The compounds help speed the healing of the grass by causing them to form new cells and act kind of like an antibiotic to prevent infection. The chemicals from some plants, when combined with caterpillar saliva can attract certain predators to the plant to eat the caterpillars. A rather handy evolutionary tool! It's interesting to note that while it smells so incredibly good, [that they contribute to ozone formation and air pollution.]", 'For the same reasons that onions smell potent when they are cut. Plants have adapted a film that covers them. It keeps the moisture and nutrients inside. Now when you violently remove this film from thousands of blades of grass in a short period, some of the moisture bursts into the air carrying the smell of the plantThe smell you smell from new-mown grass is a distress call

Why do I see a shadow on the inside of my eye when I push my finger on the outside edge of my eye?
|
Your finger pushes against your eye and distorts the lens that focuses light on the back of your eye. A small indentation can create a black spot where light doesn't focus, or focuses very poorly. It's similar to how you can have dark spots on the bottom of a pool by distorting the surface.

Surprisingly, about 80% of people breathe out of one nostril at a time, alternating about every 2.5 hours. Research the nasal cycle for specifics. The one you are not using clogs when you are sick. Some research indicates that this can throw off the nasal cycle, but it hasn't been proven to my knowledge.

Why do we feel like we know how to do something but we just can't do it?
|
We all have a tendency to over-simplify concepts in our minds. This is a way for us to organize and plan more efficiently whenever we want to do something. The problem comes when we try to enact our simplified concepts without a full understanding of the details involved. We might have a decent understanding of them, or even a good understanding, but if there's even one important detail missing, it means it might not work properly. [edit] For example, I am an amateur web programmer. There are often times when I think to myself something like "It should be very simple to make a navigation bar with drop-down menus that show up when you mouse over them." So I plan out all of the sorts of commands and elements needed. Then I start writing and come to find out that the commands don't work as I expected. So I have to go looking for explanations, examples, and the correct information. I learn quite a bit about what the commands I was using actually do, and about some commands I didn't even know of. I probably never would have come up with a good result on my own.

How do sharp angles on a vehicle affect a radars ability to detect it, such as the USS Zumwalt
|
I think a [picture is worth a thousand words] in this case. I find it hard to describe what's going on without a visual aid. With a curved surface, the radar hits and spreads out. A lot of the signal gets spread all over the place, which means there's a lot of it headed in the direction of the radar dish. There's a lot headed *away*, too, but the dish doesn't really care as long as it gets a signal reflected back at it. No matter how the plane or ship is oriented, there will always been some of the radar signal reflected back towards the dish. With a flat surface with lots of angles, the signal is scattered pretty much in all directions. It's kept in a tighter beam of radio waves, instead of spreading out. A *lot* less makes it back to the dish. Sure, if the flat surface is perfectly perpendicular to the dish, it'll show a pretty good sized picture, but that's a big huge if. The plane or ship will never be at such a perfect angle. Even if it were, that image will only last for a fraction of a second, until the plane or ship turns ever so slightly so the reflection is pointed away again. Also, just for what it's worth, both the ship and the B2 are covered in radar-absorbing paint to further reduce the radar cross-section by simply reflecting less radio waves *at all*. EDIT: Made a better picture. EDIT: u/Sythus is right and I updated to fix my mistakes.

Why can't I sleep before a stressful day?
|
Because you are expecting something stressful. You should know though that there are different types of stress, happy stress and bad stress. Bad stress is when you know that there is a test coming up and you haven't studied. Good stress is like Christmas eve. For instance, you stay up all night Christmas eve because you know there will be presents, you know that you are going to be excited. Your brain reacts accordingly, it gets excited too. Now when your brain is excited it has lots of chemicals flowing through it. These chemicals keep you up on Christmas eve, and they are the same chemicals that keep you up the night before your test that you haven't studied for.

Open Carry Laws in California
|
You cannot open carry any gun in California except at shooting or hunting events, or if you specifically have a permit to carry, such as a permit to carry a concealed weapon. This is for all guns, not just handguns, as laws were recently passed to this effect. This applies to both unloaded and loaded weapons. You can transport guns in say the trunk of a car, as long as it is not exposed to the public. You can also transport unloaded guns to/from a car.

Why do cameras have a maximum SD card capacity?
|
Digital cameras basically run an OS much like a computer. If the kernel, or BIOS, was limited to addressing a maximum size of 64 GB on a storage device, that's simply all it can see. I should note that it doesn't mean there's anything nefarious going on, necessarily, it's just a limit of the architecture they're using.

How come airlines are able to stream live satellite TV to their entertainment systems, but have trouble providing stable on-board internet access/Wifi?
|
Beaming TV to the plane is a one way connection. WiFi and Internet require asking for data and waiting for the requested data to arrive, then asking for more. Satellite TV is just a constant stream of data, just show what you get. Missed a packet? Too bad, pick up from the next keyframe. Don't want the data? Turn off your receiver, it'll still come to you though, you just won't decode it", 'A live tv broadcast is probably already being transmitted from space through the atmosphere to earth and the plane just has to pick up that signal once and show it on all the screens. On the other hand, proving stable internet access requires a dedicated two-way connection to the satellite that must be shared with all other users and every video streamed requires its own bandwidth to send, which results in very expensive access costs so the plane operator has to limit the capacity of each plane.

Why do TV actors earn residuals upon re-airing for their performances, but recording artists don't earn a dime when their music is played on the radio?
|
This answer is gonna be totally unsatisfying, but its the answer Because thats just how the business model those industries work. Yes I know, unsatisfying. Here's some details. For actors, they are members of unions, and these unions have negotiated rates and pay like this. The unions are VERY strong and active and have been able to get fairly good deals in stuff like this, they have been around a very long time, and are a huge part of the industry and giant player. In music, there are no such unions among the artists. It's very every man for themself. In music the artist doesn't even get paid for radio play. The songwriter and publisher get paid, not the artist. The music labels hold most of the power. In other words, actors, through their union, secured pretty good rights and pay for residuals. Musicians being a more disperse and non-union thing, have never been able to do it, and the power really resides with their label, so they have no reason to pay them anything.

Why do spins/jumps in sports continuously get more intense?
|
It's primarily two things: 1. Better equipment. Technology plays a larger role in these things than most people realize. Simply the fact that modern equipment is lighter, stronger, has more flex, rebound and spring allows athletes to do things that were literally impossible 20 years ago. 2. Athletes start training at a much younger age now. They are able to master many techniques sooner - including those techniques that led to that first backflip or triple McTwisty or whatever. Instead of figuring out how to do something, they learn how to do it and figure out how to improve on it.We surpass our own limits all the time. As soon as someone can do a double backflip and nobody else can then they have an advantage over everyone else. So everyone else needs to reach that level.In sports like snowboarding and BMX, equipment is always improving and the designs of jumps and pipes are also being tweaked and improved, so it makes those tricks more possible. Snowboards in the 90s were nothing compared to what we have today, and half pipes are also being built bigger and more precise. Look at videos of Ross Powers in his prime and you can see how much smaller the pipes were than what Shaun White rides now. In skateboard half pipe, on the other hand, the boards and pipe haven't changed much in a while, and contests are very similar now to when Tony Hawk was in his prime. As for how figure skaters are doing crazier things, I have no idea, maybe just humans perfecting techniques and improvements in training methods.

What causes free WiFi hotspots at hotels etc to be so patchy and unreliable.
|
Setting up a wifi mesh is expensive, and frankly not worth the effort and cost for many small motels. Larger ones try and do cheaply. The effective result is, small motels just put a consumer router in the lobby or manager's office, and it's range is a hundred feet from there. Large ones may have a mesh, but insufficient access points to cover the entire complex.

Why does the moon cause waves in the ocean but not on smaller bodies of water like lakes?
|
Firstly, the other responses suggesting that tides are not waves are incorrect - tides *are* waves, they just have a very long wavelength . To actually answer the question, it's because lakes are generally too small for the tidal effect to be significant. Tides are caused by the gradient in the gravitational field of the moon across the earth. Oceans are very large, with length scales of thousands of kilometres, so the difference in gravitational potential across them is large enough to form waves of significant amplitude . Lakes are much smaller, so the effect is also much smaller. They're still influenced by the lunar gravitational field so they technically will have tides, they will simply be a lot smaller than oceans. Another, minor factor is because oceans have a length scale that is large enough for the coriolis effect to be significant, you can get an amplification of tides in certain regions which isn't possible in smaller bodies of water where the coriolis effect is too small for more information).
|
Why does the value of currencies fluctuate?
|
The fluctuations are a result of supply and demand for that currency. For example, let's say there's suddenly huge global demand for American widgets. Companies all over the world want to buy those American widgets to sell in their own countries. Those foreign companies would drive up the demand for US Dollars in order to purchase the widgets, which makes US Dollars rise in value in relation to other currencies. There are better examples and explanations as well - try using the search bar to see if you can't find any of the previous answers.

I don't know about the situation you're describing, but I did slice my thumb pretty badly as a child and now my lines on that thumb print don't match up, so I know you *can* damage your fingerprints, but I don't know if you completely removed them what would happen. Sorry my answer isn't helpful, I'll delete it if anyone comes along and actually answers you.

Reddit bots. What are they? How do they work? Who makes them? How do you make one?
|
A bot is a computer program that performers automated tasks . Bots run on a server and the bots you see posting comments on reddit are usually run independently by individual users who create the bot scripts and host them on their own servers. There is also a Reddit AutoModerator bot that subreddit moderators can use to help automatically filter certain types of content and perform moderator operations automatically. Bots are typically written in a scripting language like PHP or Python, but technically can be programmed in other languages like C++ or C# as well. In order to perform operations like accessing content on reddit and posting replies, bot programmers use Reddit's [Application Programming Interface] . An API allows you to develop applications that interface with third-party applications or services to directly request specific content or perform certain operations that users would normally have to use a Graphical User Interface to accomplish.

Why do we consciously make bad/wrong decisions, even though we know the outcome will be bad?
|
Humans are wired to forget how a bad experience **feels**. You get arrested, the entire experience sucks and you're miserable. The next week, you're looking at it and laughing about it. It's the same reason people are easily trapped in toxic relationships. That terrible fight you had last week seems like it wasn't a big deal until you have it again. It's not necessarily a bad thing though. It also allows you to forgive and keep trying even after experiencing failure. Here's a TEDtalk on the subject: _URL_0_", 'humans are driven by not only logic, it involves a complex system that interacts with emotions,memory,fear and agenda, so this is why people may make wrong decisions even when they know the outcome may have negative impact upon them or around themHa! I 've been working on this question for a while due to personal experiences. My current argument is that short term relief of stress wins over long term release of stress, specially when the short pathway is assured and the long pathway is uncertain and/or risky. There are many reasons why this may be like this. Basically, different people are wired differently by both their biology and their experience. Trauma & stress bring about subjetive states that are hard to endure, and we tend to avoid them in any way we can because we understand them as "harmful". When such states come about again, we are motivated to "solve" them by commiting to short term solutions that most likely do not address the underlying reason why we decided on it. They, however, will triger the appropiate reward systems and the related sensations of wellbeing. Such reactions then become a go-to solution, and no further actions are necessary to address the problem. So, it's easier to fuck up than to do the right thing .

Why nuclear plant computers are connected to the Internet and vulnerable to cyberattacks?
|
Imagine you have a computer on your house. Now you want to connect that computer to your friend 100 miles away. How do you do it? You could lay a 100 mile cable, but do you have the permissions to dig up roads and pathways? You would use a company whose cables were already there, and just use that network of cables to access you friends computer. This is exactly what these power stations do - along with a large amount of other businesses. However there are ways to keep the data being transferred secure; like VPN and encryption etc but that's a little more than ELI5.

Why does shaking a liquid mix everything together and not separate it?
|
It's called agitation if you were to spin it with screens finer and finer toward the outside you would then separate it,but thats only part of it the lighter material will go to the top so you could actually just stack screens one on top of another and separate elements that way", 'when you shake the bottle you give the atoms energy, this energy creates creates movement, movement creates chaos, chaos becometh the mixture. when you spin, for example in a centrifuge, the heavier atoms fall and displace the lighter ones. you can also see this without a centrifuge if you put oil and water in a container and shake it, it will emulsify and then it will settle, with the water displacing the oil and pushing it to the top. Hope this cleared it up a little', "From a theory standpoint, it's the law of entropy. Chaos in a closed system must always increase. From a practical standpoint, contemplate pouring a salt shaker and a pepper shaker in a glass, and shaking it. The salt and pepper mix, right? Liquids are doing the same thing, just with smaller bits. To really make your head spin, try to find out how a centrifuge separates liquids. Pun absolutely intended.

Why do wedding dresses turn yellow after a period of time?
|
Many white things turn yellow over time. Generally it's the result of sunlight or oxidation. White cotton generally gets its white color from being bleached and washed with fabric whiteners. Fabric whiteners and brighteners are temporary dyes that add a slight blueish tint to the wash. Modern ones use optical brighteners _URL_0_ In the old days people used Reckitt’s Blue, which was a blue bar of soap, which was scrapped and the flakes added the wash. It coated clothes in a blue powder that made yellowish clothes look white at least until the powder fell off from wear. Edit: minerals like iron in the water, makeup and sweat also make white clothes turn yellowish.

How come most houses have slanted roofs but most other buildings are flat?
|
In the old days roofing materials were not as great as they are now. Traditional materials need a good slope to shed rain properly, and even more so to shed a heavy load of snow. Modern materials are tougher, but generally people building homes enjoy a traditional style because tradition feels cozy to many people.It's a lot cheaper to build a slanted roof in northern climates because snow tends to slide off of it. To build a roof over a Home Depot with that kind of slope it would have to be pretty high, so they build a flat roof with more expensive materials instead.Having a slanted roof helps keep the HVAC system more efficient. It leaves a pocket of air above the ceiling to act as insulation from sunlight hitting the actual roof itself.

How is Oxygen stored in water and how can fish extract it to breathe?
|
Oxygen is just dissolved in water, in the same way that you can dissolve sugar in water, or carbon dioxide in water to make a soda. Fish gills have a huge surface area to maximize how much contact they make with the passing water. Oxygen molecules cross the membrane of the gills just like they do in our lungs, and then get carried to the rest of the body through the fish's circulation!", 'The oxygen is dissolved in the water. Fish have gills which absorb the oxygen as the water passes over them.

Why Americans are more conservative and religious than Europeans ?
|
Well, I think it's just that Americans are louder and hence given more coverage. I'm from England and there are *plenty* of old conservative folk here, who hold the same opinions as white old Americans. I think, in my opinion, they're a little nicer about it and don't go out of their way to show hatred. Yep, people are very conservative here - especially in little "cathedral" towns or villages, but they're quieterThey put a bunch of religious nuts on a boat 400 years ago. What do you expect? :DOur Puritan history probably has something to do with it. Then the Red Scare in the 50s really super-charged religion in the US . I think this is a major reason behind it actuallyOne contributing factor is rural versus urban populations. Europe is a lot more densely packed than America. Rural populations tend to be more religious and conservative and urban populations tend to be less religious and more liberal.

What is the Louisiana Cajun accent
|
Cajun Vernacular English is the dialect of English spoken by Cajuns living in southern Louisiana and, to some extent, in eastern Texas. Cajun English is significantly influenced by Cajun French, the historical language of the Cajun people, who descended from Acadian settlers and others. It is derived from Acadian French and is on the List of dialects of the English language for North America. This differed markedly from Metropolitan or Parisian French in terms of pronunciation and vocabulary, particularly because of the long isolation of Acadians, and even more so of Cajuns, from the Francophone world. English is now spoken by the vast majority of the Cajun population, but French influence remains strong in terms of inflection and vocabulary. Their accent is quite distinct from the General American. Cajun French is considered by many to be an endangered language, mostly used by elderly generations. But Cajun English is spoken by even the youngest Cajuns, and is considered to be part of the identity of the ethnic group.

Why are so many health issues worse in the early morning?
|
It really depends on what disease you're talking about. Whether this is a muscular or joint issue or whether it's to do with your organs. And, what medicine you're taking. In your case you suffer from asthma. The respiratory system slows down and depresses during sleep, as part of your metabolism. Your airways are already narrower and more prone to inflammation due to the disease. Depression of the respiratory system during the night makes it worse. The result is that mucuous builds up during the night. You may have also possibly had a chronic lack of oxygen during the night, aka sleep apnea. If it was a physical ailment, such as arthritis. That can be explained through muscular and joint theory. Healthy muscles need constant movement. Often, at night one is stationary for prolonged periods of time. The stiffness you feel in the morning is a combination of two things. The muscles tightening dependent on your posture . And also, within the joint itself the fluid that lubricates the joint, changes viscosity, becoming thicker and stiffer. Movement and warming up in the morning counteracts these effects.

Why is there ringing in your ears in complete silence?
|
there are little tiny "hairs" in your ear that are actually very sensitive cells that detect vibrations in the air that you brain interprets, thus, you can hear things. Sometimes, these little "hairs" get flattened out, by a very loud sound or by a natural quirk in your body. The ringing you hear is the the cells straightening themselves back out slowly. Imagine them like carpet that was under some furniture that you just moved. Your brain is wired to interpret any movement from them as sound, so you get that phantom sound at a low level as they stand back up. Edit: Children of Men was an AWESOME movie, but the whole swan's song theory is a common misconceptionI think that I know what you are talking about, what it could be is tinnitus. It may sound bad, but it is just a condition where you hear a ringing noise in your ears. It can be caused by a large number of things including an ear infection or an ear wax build up. I have tinnitus and what I do to cope with it is just listen to music whenever I can, it tends to help. I hope I was able to answer you questionIf the sound is hearable and distracting go see a doctor.

Why is it after a person is saved from a fire, they are wrapped in a blanket afterwards?
|
generally I think it is a thermal blanket which helps against shock.Truth is: Its likely you're not prepared for the elements outside. Your house is on fire and you need to get out. Oops, better stop to get that sweater, there is a chill in the air said no one ever. Beyond that you're likely about to start coming down off a pretty serious adrenaline rush. You're gonna crash hard. Beyond that, your peripheral blood vessels have all constricted so you're gonna be very cold and clammy until you get back in order. The blanket keeps you comfortable.Shock makes the body susceptible to hypothermia. If you ever see a person with an injury acting way too calm or someone after a traumatic event that is behaving strangely or with a blank expression, get them a blanket.The number 1 killer in burn victims is fluid loss leading to shock. Shock is a condition where your organs and tissues are generally not getting enough oxygen/blood delivered to them. Without proper oxygenation your cells can't produce energy/heat properly, thus leading to cold. Also, a burn patient may have nerves exposed which are sensitive to the cold if their top layer of skin and fat is destroyed.That is why burn patients must be shielded and have a large amount of fluid pushed into them via IV. EDIT: fixed typo", '* while there is a fire, you get out of your house without worrying about warm clothing, and there is a good chance you will be standing around for a while* warming someone up is a good treatment for shock, and blankets are comforting in general* in a movie, it is a way to emphasize someone was in danger, but now are safeWhen you are severly burned you lose your thermoregulatory skin and therefore can go into hyperthermia at a higher temperature. This is why a burn operating room is kept at ~90 degrees F. Source: _URL_0_ However, in that case it seems like it was likely to prevent shock and comfort her.

How exactly does NATO work?
|
Article 5 is the most important, and the one you hear about day to day - an attack on one NATO country is an attack on all of them. Developed as a nuclear umbrella during the cold war, the design was to contain any Russian expansion. Article 5 has only been employed once: after 9/11, the US declared that Afghanistan had attacked them. This decision was not popular with other NATO countries. Article 4 basically says that NATO countries can call a NATO conference to discuss any issue and, if they can all agree on something, they'll all implement it. This comes up more often than you would think, but rarely produces tangible results. Article 3 sets ambiguous requirements that NATO countries maintain adequate armies, because they don't want countries to rely on the rest of NATO while ignoring their military. Canada is sometimes accused of violating Article 3, for example. Article 2 states that nations in NATO have to be friends, can't employ mercantilist trade policies designed to harm a member nation, and must strive for free trade. They also need to support international NGOs in their country. And lastly, Article 1 states that members must try to resolve disputes peacefully and maintain the role of the United Nations in bringing 'Justice' to international disputes. This is the article that lead to the NATO interventions in Kosovo and Libya and to anti-piracy operations in the Gulf of Aden. The role of NATO then collectively is to enforce the World Trade Order, wherein nations of people coexist peacefully with free trade and local sovereignty. Much as we trade with China in hopes that we will inspire them to change , NATO is empowered to promote and defend a world order that ends with all nations coexisting peacefully under international law, with universal free trade and strong international development. It gets a lot of flack, but in practice when it actually does act, it usually comes out looking like a hero.

Why are typhoons named but not other natural disasters?
|
Hurricanes are named by the World Meteorological Organization specifically to make it easier for people to find and track news about them in order to better prepare. Hurricanes, unlike a lot of other natural disasters, are big lumbering things. You rarely are caught off guard by them, as our ability to track them means we know about them weeks ahead of time. The key to safety for a hurricane is to get people out of the way of them. So the easier we make it for people to consume news about them, the easier we make it for people to know they need to get out of the way.Typhoons here in the Philippines are named alphabetically so its not random here, I'm interested to know the rest

Is there any way to sort out your childhood memories to figure out which ones are yours and which ones you've incorporated into your own memory because you've heard the story so many times?
|
Background setting is the main distinguisher between real and constructed memories. Can't remember if it's is really a memory or you're reconstructing the scene from what someone has told you? Try to remember the details. Do you just remember your grandfather and the piano, or can you describe the room? What was he wearing? Was he holding anything other than the licorice, or did you have anything else with you like a stuffed animal? Good luck and I hope this helps.

Why that the deeper you go in the ocean, the uglier the wildlife gets.
|
this is subjective, but the reason morphology is so different at deeper levels is because the environment is so drastically different from our own. humans are predisposed to like creatures that are most similar to them and which have traits similar to them and their offspring. fish are obviously very different from people and so that makes them seem "uglier" at deeper depths the environment requires that creatures be physiologically very different from ones near sea level to cope with the pressure and darkness. this drastic change in physical features from our own is what makes them look so unappealing. however there are also plenty of creatures which one might find "pretty" as some of them glow or look cute in other ways.different conditions lead to adaptation for different characteristics. the further away from the conditions we are accustomed to, the more widely the characteristics will be. extreme differences are often regarded as 'ugly'.

Why some nations/states/regions are more conservative/liberal than others.
|
it seems throughout history coastal areas tend to receive information faster, and so the coasts tend to be more liberal than the inner states.Also certain states have more of a "culture " that is perpetuated due to condensing of immigrants. For example the mid west has a history of dutch,swedish and german immigrants settling there, so there is more of a concentration of those cultures. . Similar to the south west US, where there have been alot of central american influx. In the beginnings of the US, the british settled New England, alot of the west coast and alot of the South settled by the Spaniards. then Lewis and Clark went on their expedition and alot of people in the East Coast headed out to the west coast because they had a chance to have space, their own land etc. The South eastern coast has been influenced by the Caribbean, especially Louisiana it seems. Culture travels with immigrants and people, the culture , traditions and ways of thinking travel to the new place as well.

Why are calculator numpads vs. phone numpads vertically reversed in number order?
|
Actually, keypas on the Calculator and on the phone have different developments: For Calculators, the old mechanical machines needed a deeper keypress for higher numbers, and those can be achived easily on the "back" of the keypad as it is higher. When the first electronic calculators were developed the Layout was inherited. Older phones on the other hand had [dial plates] where the numbers went from 1 to 0. Newer phones with a keypad inherited the same order resulting in the now known keypad./u/5nafu pretty much has the right of it, but there was a lot more human factors design involved that they mentioned The biggest reason they're different is that at the time touch-tone phones were invented, the Adding Machine was still pretty much the province of professional actuaries and accountants They did a bunch of really interesting research about what layouts allowed more speed vs. which had more precision it's all detailed in this excellent [Numberphile Video].

How do people who release leaks on to torrent websites originally obtain them ex. Game of thrones
|
There's three reasons why TV shows or any other media is leaked: - The production crew is huge usually hundreds of people. Someone such as an intern could easily steal a tape from an editor or someone in a similar position and then go home and upload it to the internet. - The company producing the show also sends out review copies for early reviews. One of these people who receive a review copy could upload it themselves. - Sometimes companies purposely "leak" an episode of their show to get public interest going or free advertisingUsually reviewers receive advance copys of something to review.

When we say someone has a "good" or "poor" vocabulary, how many words more or less are in their functional command?
|
Depending on who you ask, there are around a million English words. You can take vocabulary tests that check you know just a couple of hundred words, chosen to cover a wide range, and they tend to tell you how many "word families" you know. The idea of a word family is explained as > words such as nation, national, nationalise, and international are all considered to be members of the same family Apparently native english speakers know some 20,000 word families. If you know more than that, your vocab might be considered "good", if you know fewer it might be considered "poor". I just took one of those I found from google and it said [26,900] word families. I don't know how many I got wrong, but that might give you an idea of the general range we're talking about. Edit: I did a different one which said [27,800], so you can see this method has some variance in itI think [this answer at _URL_3_] explains the answer pretty well. Here is an except: > There are too many problems defining concepts such as word and know to confidently state something like "_There are x number of words in your vocabulary_".

What happened to /r/circlejerk?

/r/atheism and /r/politics are two subreddits that provided a lot of material /r/circlejerk can make fun of. The joke is that since those two were removed from the default subreddit list, there's a lot less circlejerky material and what is left needs to be rationed. That it doesn't make any sort of actual sense is completely irrelevant to the joke. In case you need to know, in real life, rationing is used when supplies of a particular product are low. You limit everyone to a maximum portion, or *ration*, hoping that will last until you can get more. Since rationing is usually used for essential products like food, if you didn't ration, you run the risk of either running out or people buying more than they need because they're afraid it **will** run out and thus running out.r/jertalk the ultimate circlejerk, pretending theres a magic place where awesome things happen and you are not part of it.

What a Roth IRA is and when it is a smart investment choice
|
A Roth IRA is an account you create that has tax advantages over other investment accounts. If you make contributions into the Roth IRA and keep them in the account until you turn 59 1/2, then you can take distributions from the account tax free. There is a catch, though. If you take distributions from the account before 59 1/2, there's a good chance you'll not only have to pay tax on the earnings, but also pay a 10% penalty as well as possible penalties to your state. Is it a smart investment choice? Well, if you are certain that the money in the investment isn't going to be needed until retirement, then yes, it's a smart choice. If you aren't sure, then it might be better not to use the Roth IRA.

There is an overriding concept in the American view of government: All government information is public unless there is a really good reason for it not to be. The law in most jurisdictions reflects this: citizens have a right to government information unless that information has been, by law, specifically excluded from disclosure.There's the Freedom of Information Act which allows citizens to request public documents from the government. There are some exceptions to it, as classified material, and anything that would violate the Privacy Act can not be handed over, but otherwise yes.

Do today's video games keep you playing like casinos do, throwing you wins once in a while to keep you playing longer?
|
There have been news recently of a patent filed by Activision for a system designed to goad players into buying more microtransaction items by doing things like matching them up against better players with premium items that the manipulated player doesn't have, to make them believe that they would be more successful in the game if they went ahead and bought the premium item. Directly after the purchase of the item, the game would make sure to match the players against worse opponents to make them feel good about their purchase. Activision claimed they haven't implemented the feature into any of their games…yet. Edit: For a somewhat more positive example from the same company, Hearthstone has a system where the chance of getting a Legendary card inside of a pack slowly increases the more packs you buy, to the point where you are absolutely guaranteed to get at least one Legendary every 40 packs you open.

Why does it hurt to move a limb after it "fell asleep"?
|
You have nerves in your body that send signals to different parts to work-- specifically muscles. They begin from your spinal cord, branch, and extend all the way to your fingers and toes. Your arm or leg falls asleep when pressure is placed on the nerve or when blood is cut off from supplying the nerve. The effect is similar to when you hit your funny bone which can be painful, and cause the pins and needles sensation. People with more common nerve compressions which can be chronic may have diagnoses such as sciatica or carpal tunnel syndrome and experience a range of painful symptoms.

- Why do smells get "burned in" to your nose? (Bleach, vomit, etc)
|
It's because those particles are in aerosols, little droplets of water with other things mixed in. And those droplets get in your nose and deposit their contents on the mucosal lining. Eventually you secrete enough mucus to wrap them all up, you swallow that, and it's gone. But until that time you can still smell them because they are still there, just hanging out inside your nasal cavity.

To get your product mentioned on TV to millions of people is valuable. Next time they're at the store, they may think of trying it.

Why Muzzle velocity is measured in feet per second rather than mph/kph.
|
Because bullets generally travel in units of feet rather than units of miles and the United States uses the Imperial system rather than the metric system for common units of measureGravity will pull a bullet to the ground at the same rate as if it were just dropped. It takes roughly half a second for something to drop from 4 feet, so if you know the muzzle velocity of a gun, you know approximately how far it will travel before it hits the ground. Just divide muzzle velocity by 2. If muzzle velocity is 1000 f/s, the bullet will hit the ground about 500 feet out.Generally you're not worried about trying to hit targets that are miles away, but rather you're aiming tens or hundreds of feet away. Knowing how many seconds related to feet is more useful because you measure distance to target in feet. Similarly, this is why in metric this is generally given in meters per second rather than kilometers per second.

How come after drinking a lot of beer (calories), I want to eat something bad for me (more calories).
|
This is going to be a very simple explanation, there are a lot of biological factors involved but this is basically it. Alcohol is a depressant, when you get drunk your consciousness decreases based on how much you drink. When this happens, people tend to become very instinctual. You start trying to fulfill your instinctual needs Such as sex, sleep, and hunger. Now we go to the past, long story short, humans LOVE fat and greasy stuff. It kept us warm in the past. So essentially, in your stupor state, you tend to like more fatty foods due to evolutionary instincts of liking fatty stuffs.

What mental effects does catnip have on a cat?
|
Catnip isn't psychoactive. It smells a lot like kitty pheromones. A cat's reaction to catnip is a reaction to feline sexy-time smell. [Here's] a neat iO9 article about it."The most intense catnip experience is an olfactory one—your cat smells the herb and promptly goes nuts.\xa0Researchers aren't sure what the neurological explanation is, but it's thought that catnip mimics feline "happy" pheromones and stimulates the receptors in the brain that respond to those pheromones.\xa0When eaten, however, catnip seems to have the opposite effect: the cat may become very mellow. Most cats react to catnip\xa0by rolling, flipping, rubbing, and eventually zoning out.\xa0They may meow or growl at the same time. Other cats become hyperactive, running around like their tails are on fire, and some get downright aggressive, especially if you approach them.\xa0They must protect their toys! Usually these sessions last about 10 minutes, after which your cat loses interest.\xa0It may take as long as two hours for him to "reset" and become susceptible to catnip again. An estimated 50 percent of cats don't respond to catnip; it's an inherited sensitivity." Source: _URL_1_', "i came into here because i was curious about the effects from eating it. sounds like they are minimal or not the entertaining part though, correct? i recently volunteered on a cheetah project and was allowed to try the catnip out with the cafe cat, african wildcat, and the servals they had there, but not the cheetahs, for fear of an adverse reaction. although i think one of the managers had already tried them and found no reaction. cheetahs have a poor sense of smell because they evolved simply to have massive oxygen intake systems to run, at the expense of everything else. here is a video of the servals and wildcat. one of the servals didn't care too much. actually he never did much at all if you look at my other videos. the same one loving the 'nip here is the same one jumping around in the other vids. the other guy just lays around lazily all day. _URL_2_

why were tv and movies black and white?
|
Because the technology of how to create black and white photographs and moving pictures came first. Television at first was black and white too even though color movies already existed at that point. The technology to make color-tv was more expensive than b & w tv and the receivers for color were also more expensive. During the early phase of adoption they had to add color information in such a way as to not break anything for people with b & w tvs while allowing those with expensive new color tvs to get a color picture from the same signal. During the phase before it became normal some producers would create and broadcast shows in b & w despite color being available because it was cheaper to do so and not many would have the color receivers to see the difference.Your eyes perceive color by sensing varying combinations of red, green, and blue light. To reproduce this for film originally required three separate strips of film to capture the image in each of those colors that had to then be assembled into a single strip for a projector. It took a while to figure out how to do that, to find the right photosensitive chemical dyes, and how to assemble the colors into a single film. B & W was just cheaper and easier. Color film was available for decades before it became the standard, but it was reserved for epic productions because of the expense. *Gone With the Wind* wasn't even the first color movie, but it came out in 1939 and still B & W was common well into the 1960's.

Why are people with a latex allergy also allergic to bananas? What's the connection?
|
The banana contains a protein which is very similar in chemical structure to latex. So if you're sensitive to one, there's about a 50% chance that you're sensitive to the other as well. _URL_0_

How does memory get stored in HDs, SSDs, and ram?
|
That is a complex question. There are quite some different methods used to save the data. Put simply SSD and HD are non volatile memory while the ram in your computer is volatile. Meaning if there is no power - the ram loses the stored information. HD with a spinning magnet disk work by changing the north or south pole of the logical units of the magnetized coating of the disk. It works mechanical and therefore is slower than the other two. RAM and SSD work with memory chips. RAM can't hold the data, SSD can. I tried hard to eli5 the mechanism of how flash memory and ddr sdram save data but failed.

why it goes vitamin A to E, then jumps to K. What happened to F to J?
|
Most of them were renamed upon being grouped into the B Vitamin group; for example vitamin G was the old name for riboflavin, which later became known as vitamin B2. Vitamin F was different: It was the old name for essential fatty acids, which were considered vitamins at the time of their discovery but have since been reclassified as fatsInteresting fact, Malk is an excellent source of Vitamin RBasically, they though there were going to be way more vitamins than they ended up being.[Demetri Marting clearly expains it]Fatty acids are a part of a cell which makes up the cell membrane. Right?That would be awesome if we had all 26 letters as vitamins. There could be a whole pseudoscience about it, like eat more Vitamins G and C to be more like George Costanza. Sell combinations like Vitamins L,O,V,E as a surefire way to turn your pheromones on..etc.

Why helicopters and planes can't get out of the earth?
|
They need to push down on the air to keep flying. In space, there's no air to push down on. Eventually, the air becomes so thin that you can't push enough of it down to keep yourself up. You can swim in water, because it's dense, and you can push water down and pull yourself up as a result. Now try swimming in air. Not as easy, eh? Not enough air to push down so you can 'swim' in it. It's the same thing for planes and helicopters, it's just that since they can already fly in air, their critical point happens when air is a lot thinner.

If all humans switched to a plant based diet, and all meat, dairy and egg industries disappeared, how would this new and increased demand for plants based foods affect the environment?
|
The animals we grow to make meat, milk and eggs contribute to half of global greenhouse gas. This number takes into account not only the fossil fuels used to produce and transport livestock before and after slaughter, but also the other gasses that livestock produce on their own. These various gasses are referred to as carbon dioxide equivalents .Of the gasses generated for production of meat, beef is the highest contributor, generating about 30 pounds of CO2e per pound. Poultry is second with 19.5 pounds generated between chicken and turkey production while pork comes in last at 13.3 pounds of CO2e per pound of meat produced. Compare that to broccoli. It generates 2.2 pounds of CO2e. That's a lot less! Too much CO2 in the air traps gasses and particulates into the atmosphere, contributing to climate change and pollution. It takes 9 trees one month to scrub 10 pounds of CO2 out of the atmosphere. 1,600 trees are being cut down every minute just so people can eat meat. That’s 1,600 fewer trees to keep excess CO2 from contributing to pollution and global warming…every 60 seconds. If you eat meat every day 15.8 pounds of carbon dioxide emissions go into the air. If you eat a plant based diet only 6.3 pounds go into the air. So there you go my little friend. If you stop eating meat you might just help stop global warming and pollution and help save the world.Corn is horrible for the soil, so we would probably have more fertile soil. We should be growing up, instead of in fields. Large greenhouses that go up many stories. Each city could have one big enough to sustain the community. We already know how certain plants are harvested, so we could use robots to pick the yieldAnimals need plant based food. They need lots of it to grow a kilo meat, produce milk or lay an egg So if we are not talking about hunting wild animals we would have more space to plant human food. Actually so extremely much more space to grow human food that we could stop burning down forrests for that space.
