How do Bus stop buttons work? | As others have said, it's probably wireless. If you don't mind the lagality of it, a fun practical joke would be to steal the button and carry it in your pocket, and whenever a bus passes by, press it. |
Why do plants that are not desirable for gardening become invasive species, but the plants from my local gardening center that people plant in their front yards all the time don't become invasive species? | Some plants have qualities that make them hardier, faster growing, and more likely to affect the health of other plants. In Texas we have this weed called Johnson Grass. It's the worst. It grows much faster than other plants like lawn grass, sucks tons of nutrients from the soil which hurts your lawn, and it's almost i... |

Why are there only two companies who make GPUs and CPUs? Shouldn't there at least be foreign competitors? | For CPUs, Intel and AMD have a licensing deal; Intel licesnes x86 to AMD, AMD licenses AM64 to Intel. This was perhaps ironically done in the first place for competition and parity between the companies, but regardless Intel has no reason to license x86 to any other companies. That's a huge blow to any new company look... |
Who pays who in a multiple car collision? | In an ideal world, all drivers are *supposed* to stop a distance behind any car in front of them so that in scenarios such as this, car three would not have been close enough to come into contact with your mother's car .

The message of Les Miserables | It's moving because you paid attention.

How does port forwarding help improve ping in online games? | Others were right about port forwarding meaning you can have a direct connection to an opponent instead of going through an intermediary, but I thought I'd give some details as to why it works that way.

What happens to air that enters the body cavity during surgery? | From experience with lower GI surgery, much of it diffuses into your intestines and you can blow it out your rear. However, if you're recovering from a major surgery then there's a good chance that you are also on some sort of opiate based pain killer and a healthy dose of it at that. Perhaps a morphine or fentanyl IV ... |
- how does antibiotic resistance work? | It's evolution really. Since bacteria replicate so fast, their evolution is way faster. The problem with resistance is not that it exists, but because if you use antibiotics the wrong way, for too little time or for things that don't need it, the few resistant bacteria will survive while the others dont, leaving all th... |
How do people, or companies, with large sums of money, win court cases they "shouldn't"? | A protracted legal battle is very expensive. If a company does $20K worth of damages to me, I might be in the right, but can't afford to put my life on and spend hundreds of thousands on a multiyear legal battle. They know all they have to do is drag things out and I will eventually run out of money, and either take a ... |
If we are so much happier when we are doing tasks (ex: exercising, reading, etc.) why is our brain programmed for us to be lazy? | I think it's a product of the modern age. Everything around you now is geared towards making you lazy. Food, modern entertainment , and even our most productive tools like computers and smartphones are meant to require and inspire less effort. So the world you live in is telling you to be lazy, but your natural instinc... |
Why do people think it is OK to ask for you to do free work for them if you work in a creative field (or IT)? | Part of it is that people in those types of jobs are more likely to have started it as a hobby or also tinker with it at home because they enjoy it, or at least this is the perception of others.

- How are fuel prices at the pump determined and why do they fluctuate every day? | If they think oil prices are going up, they raise prices.

Why can I draw a straight line if I carelessly stroke my pen across paper, but not when I slowly and carefully draw one? | Signal to noise. When you make a sweeping stroke, the near linear angular momentum of your big heavy arm washes out the squiggly noise of your muscles--but at the cost of fine motor control. It's similar to the way a heavy flywheelwheel is used to even out the rotation of an internal combustion engine. |
How do hexadecimal colour codes work? | Hex just means it's in base-16 and they're doubled up because you can set the value anywhere up to Effty-Eff intead of Ninety-Nine using those two digits.

People donate millions of dollars to charity each year, but what do charities actually do with that much money? | Some of it goes to paying their employees. Some goes to research or actual aid.

If we know exactly what the human body needs each day, why haven't we created a "meal" incorporating everything necessary | Because not everyone needs the same. It would also cost a lot to make these kinds of meals artificially. If it wasn't, it would be a great invention. And additionally, most people acutally enjoy eating.with regards to your part about distributing to third world countries, "we" don't distribute food to other countries i... |
Why are most cigarettes white with an orange butt? What/Who set this standard and why? | The orange is supposed to look like cork. _URL_0_ The cork was kind of like a disposable version of a cigarette holder, which helped people who didn't want to be mushing up the end, pulling wet tobacco out of their mouths, or getting it all mixed up with their greasy lipstick. Filters came a couple decades later, and f... |
If the age of the universe is about 14 billion years old how come the diameter of the universe is 93 billion light years? | Because the universe is expanding at an accelerating rate. Meaning, it's expanding faster **now** than it was when I started typing this post. |
Can ∞ be used with a point. Like is x.∞ valid? | You're conflating a few different things here. Digits are glyphs we use to represent numbers. 0 through 9 are all digits peculiar to our base 10 notation. ∞ is not a digit - it represents something entirely different - so you can't use it in place of a digit. A number is merely a value. It can be written using digits a... |
How do small businesses which rarely seem to get patrons provide their owners a living wage? | Just to echo some of what has been said, many small businesses make just enough money to cover the owner's living income. The type of business is also a big factor. For instance, the holistic healing shop you mentioned may also have income from a webstore or other internet driven revenue. A barbershop isn't going to do... |
Why does Adobe Flash Player use all my CPU resources? | This doesn't really seem like an ELI5 request, it sounds like you'd understand a regular explanation. |
why is it that small airplanes seem to crash more frequently than large commercial air crafts? | As explained by others pilot error, but the other side is, Would you rather go through a massive storm in the ocean in a 22 foot fishing boat, or a battleship that is made to handle the punishment. There is a compounding factor here, inexperienced pilots with small planes that don't leave much room for error, a small a... |
How did the member states of the Soviet Union come to be a part of it? | Ukrainian here. When shit started, Ukrainians decided that this is the right opportunity to become independend and proclaimed a new state in Kiev.

I keep hearing people advocating for equal pay for women. I have yet to hear an argument against this. Is there one? If so, what is it? | Almost no one I am aware of is advocating that a woman with equal qualifications, experience, and abilities should be paid less for doing the same job. The main argument against the equal pay movement is their statistics compare *different* jobs. For whatever reason, women tend to work fewer hours, have less job experi... |
What do people mean when they talk about "America's crumbling infrastructure"? | _URL_0_ After the economic collapse the government cut back on spending, the problem is regardless of how much much or how little the government spends maintaining it it still gets used the same amount.

How can America that's only been a nation for under 250 years be more advanced than nearly every single country? | A lot of land and resources to work with combined with large oceans cutting us off from most European conflicts. So with our plentiful resources, cheap labor, and relative safety we got to sell our goods to everyone while they were busy fighting. This was particularly key during WWI and WWII where entire countries were... |
How do people get addicted to cigarettes if the first smokes aren't addictive? | Mine started out as one here or there, but eventually the habit became normal. It's not so much the nicotine, for me at least. It's more about the habit of actually smoking. After I eat, before a shower, etc. Almost ritualistic, I suppose. And I don't consciously think about it, I just go have a smoke.Many people also ... |
How do tails on animals help their balance? | I think it's similar to seeing a tightrope walker hold a bar or how people stick their arms straight out to the side when trying to walk a straight line. It helps balance their center of gravity. I could be wrong though. |
How do NASA and other space agencies prevent all the satellites orbiting the earth from crashing into each other? How do we launch rockets without smashing into the satellites? | The space available even in low earth orbit is still really really big. They also keep very close track of all objects in orbit, from spent rocket stages to lost tools. At least once a couple of satellites did collide because somebody failed to pay attention. Now they're tracking all the pieces from that collision |
The scrambled letters you have to type to verify your a human. | My first ELI5. Those images are called CAPTCHAs . The reason they exist is so that when registering on, say, a forum, you have to enter it so that the website knows you aren't a robot coming to spam the forum. It's barely readable for humans but near impossible for computers without advanced programming knowledge to by... |
[LI5] Can Someone explain rocket propulsion to me | You fill up tanks with a substance that explodes, and a substance that is mostly oxygen. Then you use pumps to control how much of each is allowed to be pumped into the engine You need the oxygen because the exploding stuff needs it to burn. To change the direction of the rocket, you can have a motor that aims the nozz... |
Why/how does medication (pills specifically) expire? | Well to put it simply, medication can change over time through different processes, one being oxidation . This changes the molecule , which in turn can change the effect of the medicine completely. Thus something that cures a head ache can become a poison over time.. EDIT: It should however be noted that they usually p... |
Why does the military want a multi-caliber rifle for snipers | Let's say you're a US Army Ranger sniper trying to take out a bad guy in a hostage situation. Through your scope, you can see that the hostage taker is standing alone in one room, and in the room behind him he has the hostages. The wall between the two rooms is made of drywall. One problem here is that if you miss your... |
How is Ryan Adams is legally allowed to cover Taylor Swift's '1989' album in its entirety? | There's a compulsory license for covers- the person covering the song has to pay, but the artist can't say no.

You will notice, though, that sometimes it randomly gets dark on a cloudy day. That's when the cloud's shadow lines up with your position, making it dark. |
If children's medicines are so dependent on weight for dosing (up through 95lbs +/-), why does an Epipen go to adult dosing at 44lbs (approx. 5-6 years old)? | While it is possible to end up with a lethal dose of epinephrine , the dosage available in the pen, combined with its method of delivery combine to prevent overdose while leaving an effective amount of the drug in the body's systems to achieve the temporary effects on the airway. Epinephrine is extremely similar to Adr... |
Why did Russia become a permanent member in the UN Security Counsil? | Russia was acknowledged as the successor state to the Soviet Union. That meant all of the privileges and obligations of the old Soviet Union were transferred to Russia. it really didn't make sense to pass that on to any other country, and without it, Russia would not have been bound to any treaties. |
If stars can only fuse up to iron before dying, how do we get heavier elements? | Yes the last element that star can fuse is Iron. Anything below iron will create more energy in fusion than was needed to fuse them. But Iron fusion need more energy than it create so it suck energy from the star. This is what create supernovea. A star is in a balance between gravity trying to crush the matter and fusi... |

Why it's hard to see LCD screens in direct sunlight. And while we're at it, how some screens like on the Kindle resolve this. | LCD screens depend on a light source shining through them to make the image visible. The sun, of course, is a great deal brighter. The Kindle's E-ink screen has hundreds of tiny spheres in it. An electrical charge is applied to each sphere to determine if the dark side of each sphere or the bright side of each sphere f... |
Why are we not overrun with graves? | People aren't that big when you cram them in a box and bury the box under ground. And there's a LOT of ground. We could bury the entire population of the planet in like, Rhode Island And I bet that's a gross over exaggeration. I bet the space required would be a lot smaller than Rhode Island. |
why do we have to take pills by swallowing the thint whole, why can't we chew them or something more comfortable. | Depending on the medicine you can, some medicines are even sold in powder form In some cases it's just that they taste awful, or some medicines need to be gradually released, or some need to be shielded from your stomach acid by a protective coating so they're not oxidized when they reach your small intestine. |
Why have TV networks such as Discovery, History, Animal Planet, etc. seem to have "dumbed down" their shows in recent years? | Back in the early days of cable, cable networks could not compete directly with broadcast TV. So they got by with inexpensively produced shows for a niche market. And because those niche markets were easier for advertisers to target, they would pay more than for similarly rated general programming. This business model ... |
Why has no one developed a universal outlet for use across the world rather than countries having differently shaped outlets? | Because no country wants the expense of changing their system to match some other country's standard . Only a fraction of the population travels enough for this to be a major issue for them, and there are imperfect solutions available that don't cost nearly as much as changing 1/2 the world to match the other 1/2. |
Why do we men sometimes wake up having an erection aka. morning wood? | I don't remember where I got it, but I recently watched [this] video that was pretty informative", 'Sexual arousal is also a very common occurrence during the REM stage of sleep which is the "deep sleep" stage of the sleep cycle.

Can we "observe" the doppler effect on light? | Yes indeed we can. This is how Doppler weather radar works , for instance, and how we tell how fast stars and other objects are moving in relation to us. |
How come when I’m underwater water doesn’t fill up my nose and ears and go into my body? | Fill a sink with water, hold a cup upside down and push it straight down into the water. You'll see that the water can't get into the cup because the air is in the way, and the air can't get out because the water and glass have it trapped. If you tip the glass over a little some air can escape from the raised edge and ... |
Why Apple laptops are so expensive compared to their PC counterparts. | In part it's because they're in some / many ways high quality products in terms of design and build quality.

That comes with a price tag, sometimes intentionally because low cost doesn't suit the image they want. |

When you go to bed for the night, if you are not at the sleep part of your cycle you won't be able to fall asleep right away. |
Why is anything to the power of 0 equal to 1? | It's by definition, but it's a pretty natural idea. In general, x^a / x^b = x^a-b, and the only way to sensibly extend that to x^0 is to set x^0 = 1. Note that 0^0 is a problem here, and is not well-defined . For most applications, 0^0 is taken to be 1 to avoid having to write special cases in formulas. |
Why don't name-brand food companies sue makers of store-brand knock-offs? | The vast majority of store brands are made by name brands. It's also quite normal for third party manufacturers and Packers to make for BOTH. The difference between store brand and major market brand can often be as little as the packaging. |
Why is Obama always referred to as black? Surely you would be equally as accurate in calling him white... or am i missing something? | When people say that race is a social construct, this is what they mean. Yes, there's definitely a biological aspect to it: Obama's skin is darker than his mother's and lighter than his father's, and that's controlled by his genes. However, genetics stop after mandating this and a few other traits. Despite that, being ... |
What is the difference between Christianity, Islam, and Judisim | I mean, there are a lot of differences. They all share some background, with the newer two sharing much dogma in common with the older one . One of the biggest things that separates Judaism from the other two is that Jews don't attempt to convert others to their faith and, even to this day, most Jews or people of Jewis... |
What happens if you get DDosed, and how to "recover" | Don't worry about it. The biggest denial of service attack a home customer has to be concerned with is Comcast tech support.if this is a real threat to you you might want to consider configuring your router to disallow certain protocols. for example icmp would be a good one to block as it would prevent a user from mapp... |
Why do we associate mint with being a "cooling" flavor and spicy foods with having a "hot" flavor despite them having no actual effect on temperature? | Spicy foods contain a chemicals which trick your tongue into thinking that it's on fire.

why it's hard to escape from a forest fire, even if you are in a car? | > How's possible? You should see/notice the fire from far, isn't enough to just stay away? Forests can block vision. Also imagine you are hiking a trail and you so see it, can you react in time? > And even running away from it, fire shouldn't be that fast going from tree to tree, They can move as quickly as 10 kph. A p... |
Pink lemonade. If it's not strawberry or raspberry, then what is the pink? | The taste is the same. The color is fake. Its a color marker that indicates the beverage. Pink has become associated with lemonade and pink is a pleasing and distinct color. Regular lemonade has a dull, mostly clear, slight yellow tint color that isn't all that distinctive. [but I still like it] |
why does your mouth taste horrible when you wake up? | Try brushing and flossing before bed. Bits of food stick in your teeth will get bad overnight. Or your general dental health might be problematic, try brushing and flossing more than once a day in addition to right before bed. You might suffer from dry mouth, which lets bacteria bloom in your mouth that normally should... |
Why do thousands of Muslims March against cartoons of Muhammad but not against the violence of ISIS and Al-Qaeda? | Why do thousands of Christians march against gay marriage being depicted in media but not against Timothy McVeigh, or better yet, not against the bombing of countries that had nothing to do with attacking us and just happen to share a religion with one that did? BTW there are plenty of Muslims marching against violence... |
What does Batman have against Superman? | Can someone also ELI5 how batman will manage to fight superman? I mean how does he even come close to 'fighting' him. |
Why are airlines struggling? | [Ever-rising fuel costs] are a huge part of the problem; as others have mentioned, intercontinental airliners aren't exactly cheap either, nor are pilots with 20,000 hours' logged flying time. |
Why do people still join Scientology even though anyone with two braincells to rub together knows it's a scam? | You could ask the same question about why people fall prey to other obvious scams, like psychics, faith healing, homeopathy, acupuncture, ghost hunters, etc. The simple answer is that the fact that these are scams is not obvious to everyone. As much as we like to think we're rational and logical creatures, the reality ... |
Why is the movement of animatronics so much more fluid and realistic than current humanoid robots? | The main reason is that animatronics are designed to follow scripted movements that can precisely model a human's movements. Humanoid robotics on the other hand designs motion that has the same range as humans, meaning it has to be able to move in any human-realistic way based on sensory input. This is MUCH more comple... |
Why do we remember somethings very vividly? | I think it's as simple as: they made a stronger impression on you. The events you remember stuck out more than other things that happened. So you probably thought about it more. Also, it's important to note that memory is unreliable. If you're recalling this from early childhood, it is very likely that how you remember... |
How come an individual's appearance seems to "change" depending on your feelings towards the said individual? | It's just projected bias. People are incredibly irrational and most of the opinions we have are ONLY consistent because we remember them. If you wiped your memory you'd have a different opinion on something every time you encountered it depending on your mood. This has been tested on Alzheimer's patients. My guess as t... |
Experiencing culture vs. appropriating culture | 99% of the time, experiencing a culture is what people you like do and cultural appropriation is what people you don't like do. In practice, the differentiation between the two is so mild and based on nebulous things like intentions that in most cases it's like the difference between being rude and being offensive, one... |
How do grocery stores prevent thefts when they have a self-checkout option? | I know places like Walmart have someone standing at a computer in the area, and the computer shows all the transactions going on. The person then just monitors and makes sure what is going into the bags is what's in the transactions. Also, if you put something in a bag that wasn't rung up, the transaction is flagged be... |
What, exactly, does the Air Re-Circulation button for my cars heating/AC do, and when/why should I use it? | As others have said, it causes the AC to pull air from the cab instead of outside. One way to use it on a hot day: assuming you get to your car and it's hotter inside the car then outside, start with it off. This will pull in cooler outside air, making the ACs job easier and getting your car cooled faster. Once the air... |

What is physically happening to the brain during meditation? | Different forms of meditation have different effects on the brain and so any explanation for what goes on can may make sense for a given type of meditation, and may be utter nonsense when talking about another type of meditation.
