This means that if any of that traffic is ever intercepted, all... |
Why in modern shooter video games can we do such advanced graphical rendering and physics yet we can't stop a gun barrel from poking through a wall and giving away your position? | Basically because it isn't important enough. Doing constant checks to test and see if any part of the player/weapon model is touching any environment model takes up a whole lot of system resources. It also brings up the question of what should happen when the models collide. Should a player get stuck trying to go throu... |
How does a computer mouse "know" how and where it's moving ? | my mouse has a laser in the bottom of it. As it moves across a surface, the laser reflects back into a reticle. If the mouse stays stationary, the angle of the laser reflecting into the reticle is constant, and that equates to zero movement. As you move the mouse around, the angle of reflection changes, which the mouse... |
Why did magazines and newspapers think they could sell phsical copies while putting all their content online for free? | They didn't think that, and still don't. Print media publications were among the last to put things online, and many still use paywalls. My local newspaper puts only a portion of their things online, reserving others for the print product. But, there's a lot of demand for it, since magazines and newspapers tend to have... |
Why do car blinkers never match up? | Blinkers are controlled by relatively cheap solenoids. These are not a part where the manufacturers demand a crazy high amount of consistency or quality control, and they may use solenoids from multiple suppliers on the same model of vehicle. It doesn't matter if Solenoid A blinks 5% faster than Solenoid B, as long as ... |
How does Cricket work? | Its not as simple as that, but is pretty much like that. You have 2 teams. Each have 11 players. One team bats, the other team fields.

Why when there are 2 people shooting a machine gun, does one person have to hold up the belt that the machine gun feeds from? | Helps to prevent a jam. The belt can catch on things near by. A straight feed in smooths it out for a more reliable feed. Also if you drag a length of belt against the ground it's picking up dirt and you have to overcome the force the belt resists pulling with while feeding. Technically, you don't have to now a days un... |
How does Facebook know when your message has been "seen"? | The software probably sends a packet back to the server saying "got it!" every single time it successfully displays a message. "Seen" seems to mean received and displayed, not actually looked at by a live human. Facebook is also all-seeing and knows all of your sins and where you live. I would not make it angry by ques... |
- Why is my stuttering (and other's) contagious? | It sounds like you're referring to speech errors. The act of talking is really involved: your mouth parts have to coordinate with each other in complicated movements that your brain is planning only seconds in advance. On top of that, your brain has to go through all these information processes of decoding, retrieval, ... |
Today's xkcd comic, "Where Citations Come From". | I hope this doesn't double-comment. I submitted a response and it didn't work . Here goes again: The punchline is the fact that just because a Wikipedia article has a "source" listed does not mean that fact is true. The storyline is as follows: 1. Joe makes up a random "fact" and posts it on Wikipedia 2. A news company... |

When people are banned or trespassed from large public areas, how is the ban or trespass enforced? | Large places like NFL stadiums, Disneyworld, fairgrounds, etc, don't have any real effective method of removing these "banned" individuals from the premises.

3d printers... what exactly do they do... I mean obviously they don't just make objects... right? Also how does it get done? | Imagine you take an object and cut it into hundreds of very thin but very consistent layers. You could re-assemble that object by putting the layers back together again in the right order. A 3D printer does something very similar. It doesn't have all the layers at the start, but it has a computer to tell it what is in ... |
Why does changing my position on the scale change my weight? | In a simple scale, the force is only measured at a single point. If your center of mass is over that point, you get an accurate measure. However, as you move your center of mass away from that point, you're applying two different forces - a downward force and a lateral force. Only the downward component of that force i... |
What is happening in this gif with droplets of gallium? | When two drops of a liquid touch each other, they rapidly coalesce into one bigger drop. So each time one of the small drops is absorbed by the large one in the middle, the large one expands - knocking the other drops away. The reason they don't immediately coalesce into one big drop because there's still a thin layer ... |

How can journalists protect their source but still have credibility? | There are a couple ways. - Have a history of reliable reporting and a lack of lies - not all sources will require or even desire confidentiality.- Work with other reporters who can corroborate your story.- Physical evidence obtained from sources can be used, and tested, without revealing those sources.- Certain items o... |
How are the locations and length of the dotted yellow lines for passing lanes on roadways determined? (U.S.) | [Mostly, MUTCD], basically it's a whole bunch of rules for how to build roads, built upon all the best practices learned over the years by actually doing stuff and studies. Many states amend it to add state specific rules, but it is the main guideline on how to design roads. [Section 3B.02] gives a table of speed limit... |
Lenz Law, induction etc. What causes this effect and how? | A change in magnetic flux will induce a current in the conductor. At the same time a current in a magnetic field will experience a force following Lenz Law. By moving the magnet you change the flux and you get this interaction. Once you stop moving the magnet the effect is lost. The currents in the conductor will also ... |
Is there anything different about an apple grown in an orchard by an independent farmer and a commercially grown apple? | Most apple orchards of any size are single owner, and that owner will likely participate in a marketing board.

Industry associations and marketing boards buy produce from farmers, inspect it, and... |
What are some valid arguments in favour of the proposed bombings on Islamic State targets in Syria by the United Kingdom? | It honestly won't make a difference either way if the UK decides to blow up a few targets that the US would have blown up anyway. Maybe it will make British people feel like they are contributing, and I guess that's good. |
Why do Americans think that their 'freedom' is different from a lot of other countries around the world? | A lot of Americans see having firearms as the right that protects all other rights. It stems from the idea that as long as we have a means to resist the government, they can't take away our freedoms. |
Why do flat cords tangle less | Tubular cords can be bend in all 360 degrees. Flat corded cords can only bend mostly forwards and backwards as the cord next to it prevents bending sideways. As such it is more difficult for the flat corded ones to get entangled. |
Why does food stick to a pan when it is hot but not when it is cold? | Not all foods stick to all pans like another user has said, but here is an ELI5: When you heat the pan and put something on it, chemical bonds start forming between the food and the pan. These are usually weak and you can easily move the food around the pan, or even when things have cooled down you can just scrub them ... |
In a lift if someone smokes beside you, for one's health, is it better to take a deep breath and hold it long or take slow shallow breaths? | place your shirt over your nose and mouth and breath shallow.

What do the numbers in the names of military planes mean? Example: F-16, B-2, F-4, etc. | The letters are to denote classes of craft. The numbers come from iterations. The F-22 was designed after the F-16, though not all designs make it to operation so they skip numbers. |
Why is it healthy to exercise, and how come it makes you lose weight? | We are gennetically programmed to gather energy. that means - we eat, and we get fat, so when there`s increased request for energy, we can burn fat.

Why do many parade uniforms have a chin strap that rests on the mouth not under the chin? | Former Danish Royal Life Guard here. It's placed on the "mouth" due to that if someone comes up from behind or if you're in combat, they can't choke you or drag you to the ground while pulling on your bear-skin. And it also protected against attacks from the cavalry, where it would protect your face from sabers.It's ba... |
Why does a group of people singing sound better than an individual singing ? | Because it smooths out the imperfections. One person might sing one note slightly out of pitch or out of tempo, but when you average it among 1000 people it sounds more "perfect". That's why you'll even have pop singers do muti-layering over their own voice for choruses to give it that same feeling. Also in a musical p... |
Why do kids have smoother skin than adults? | So basically, our bodies make more skin by having the old skin cells make new ones. Young people’s cells are in perfect condition, so the new cells are in tip top shape. The older you get, you have damage from the sun and that sort of thing - so the skin cells aren’t able to make new skin as well as they used to. I hop... |
It's said that a single strand of DNA contains roughly 4 megabytes of information. How exactly do they know this and how are bytes convertible to something physical like base pairs? | A bit is a binary digit. A byte is an 8 digit number, in binary. In decimal, a ten digit number could represent a high count of something, or each digit could have it's own significance. For example, in a telephone number, where it really just represents what button to press. It's conceivable that every two digits coul... |
Alford plea (aka the plea that freed the West Memphis 3 for time served) | Let's say you are accused of a crime. And even though you are innocent, the state has a very strong case against you. If you plead innocent, you will probably still lose, and get the maximum sentence. If you plead guilty, you agree to a lesser sentence, but you greatly hurt your chance to appeal, and you make it easier... |
Why can a judge not just call BS on lawyers who keep jumping through loophole after loophole to get what they (or their party) want? | Not to be a problem, but I think that if you want a satisfying answer, you may need to be more specific about the kind of behavior you want explained. After all, one man's loophole is another man's inviolable right. And, it's worth noting that judges are often pretty dependent on the parties to inform them of the relev... |
What make USB 3.0 faster than USB 2.0? | Devices communicate at different frequencies. These are when voltage goes either high or low. Each high-low cycle is called a pulse. The frequency of the pulses determine how much data you can send per second. The higher the frequency, the more pulses you get, the more data you can send. But the higher the frequency, t... |
How much growth is possible regarding the limited ressources of our planet? | [This is] a good discussion between a physicist and an economist discussing the idea.

Why does Eclipse gum come with 9 pieces per pack, not 10? Why does the mysterious empty 10th packet exist? | It isn't a diabolical plan to make tons of money by shorting you a piece. It was probably ten pieces in the past but then a price of one of the ingredients used to make it went up. This left the company to either raise the retail price of the gum or make the package smaller. The went with the second choice because rese... |
Why did almost every animal species evolve to need sleep if it makes them incredibly more vulnerable while they do it? | Oh, small mammal mother and her cute clueless cubs, listen children there are big lizardy nocturnal predators and if they hear you, you' ll get eaten, you have to hush omg they are just kids, they make all sorts of stupid noises, this is really dangerous hey what is that, why all of a sudden you are motionless and quie... |
How are coding languages written? | Most are languages extending past assembly language. Assembly is very difficult for humans to understand, but very close to true 'machine code.' Not exactly binary, but one step above it. Today, few people know assembly, and those who know it well, their minds basically ARE computers. Let's use Java for an example. Jav... |
Why will oil supplies run out? | Because we're mining it at such an alarming rate. Sure, oil is technically sustainable, but we're not giving it enough time to recreate itself. Unless this is changed, we'll be without oil for a few millenniums. |

If we devoted one year to working REALLY hard on fixing up the environment, could we stop global warming? | For one year? No. Halting humans' effect on the environment will require a permanent shift in how we act. At the moment, this permanent shift won't be too painful - however if we put it off for more than a couple of years it will be. It would require everyone to produce less greenhouse gas - to use less electricity in ... |
What are the difference between a distributed system and decentralized system? | My understanding is that a decentralized system is in the middle between a centralized and distributed system. For example Internet is decentralized, because there is no central server. Instead there are many servers that together keep the Internet running, but there is also a lot of computers that are not servers and ... |
What Is DRM And Why Do People Hate It? | The history of DRM is a nasty one. [Early DRM did things like install rootkits and spyware.] Even earlier DRM in games would be things like the solar system maps in the star-wars anniversary game, or Star control-- you'd receive a map when you purchased the game. Inside the game, you'd be directed to go to something li... |

Why does my battery stay on 100% for 30 minutes and then as soon as it drops below 100%, start decreasing much more rapidly? | To make it short, battery percentage is only an estimation. And often, a phone that shows 100% isn't really at 100% of the battery, more like at 95-98% because the charger trick charge it. Staying at 100% is really bad a Lithium battery and the charger "knows" thatThere is imprecision in all kinds of measures, and impr... |
What will be changing over the next 4 years? | Not much. People severely overestimate the power of the presidency. No, you aren't going to be raped 20 times a day.

Basically th... |
That breathing-type noise when I'm in a quiet place. | Does it happen everywhere or just in certain places? It's definitely not a phenomenon I've heard of unless there's something in the room or if the wall to your right at your desk is a natural windbreak or something. |
What will happen in the next few years to the American Economy due to Russia and China no longer using the US$, and how will it affect Canada? | The Russian-Chinese currency swap was a one time thing, that didn’t benefit the Chinese all that much.

In the winter, why do my clothes get more static electricity? | The air is much more humid in the summer, which makes the air more conductive. This means that the static electricity is dispersed into the air. The dry air in the winter doesn't allow that method of release, so the static charge builds up. A humidifier or air ionizer will do the same thing, making the air more conduct... |
Why can't flies get out of open windows as soon as you open them? | Imagine being in a very large room, and you can only see a small part of the room at any time. Someone makes a small opening in one part of the room. You can't leave immediately since you don't know it's open until you explore it. On top of that, flies are very bad at figuring out transparent obstacles. A window might ... |
why, when i get drunk, do i eat everything in my house, even though i'm not hungry? | Not sure, but I think it's because alcohol makes you dehydrated.

Why shouldn't I reheat food more than once? | Bacteria grows best in a certain temperature which is sometimes called the [danger zone]. So if you start heating your food that has X number of bacteria and it goes through the "danger zone" they will multiply as fast as they can. Now, if you take that *earlier reheated food* it will have much more bacteria in it that... |

why does switching website players from flash to HTML5 take long time? | A flash site is actually a large amount of custom-written software specifically designed to work with the flash system.

Why is it that sound travels faster at night than during the day time? | Its not that sound travels *faster* at night, it's that it can be heard along the same plane from a further distance.

Sou... |
Why is dog racing so frowned upon but horse racing is praised worldwide? | It's because the dogs are far more exploited than the horses and they are given a lowered quality of life. Racing horses, like any horse may, will live in stables. But those are the most valuable horses alive and they are taken very good care of. When they are ready to retire they are put out to stud. The dogs are kept... |
How do color blind people deal with the fact that traffic lights are red and green? | Because traffic lights [aren't one color], the red light has some yellow light mixed in, and the green light has some blue light.

Why do gaming companies not re-make old consoles and re-release old games? | If they thought it would be making money, they'd do it. They've run the idea past focus groups and realized there's not really enough of a market. For the old games that are still of interest, new consoles can download a game+emulator and play it there. |
What mechanism do self-dimming mirrors use to dim? | I did some research on this when I had to replace the one in my car. These mirrors contain a electrochromatic liquid inside, sandwiched between a mirror and outer layer of glass, that changes color while a charge is applied. The ones in your car have photo sensors, one forward facing and one to the rear. When a big eno... |
How does microwavable popcorn work? | Microwaves work by agitating the water inside food. The water heats up and heats the food around it as well. Inside the kernels, the heat is causing the water to turn to steam.

Why doesn't MADD provide funding for sober rides/taxi services? | They are more about prohibition than anti-drunk driving these days.They do help fund rides on certain nights , but they can't afford to pay for everyone in America to have free taxi rides every day. They do work towards preventative measures by educating people. |
Why is that fire smoke sticks to clothes more strongly and for longer than anything else? | Smoke sticks to surfaces about equally good or bad, just the amount of surface matters. Now think about a sheet of plastic and a dishcloth, and the smoke molecules as water. When you soak both for an equal time and then check how much water both carry, you will find the cloth holds much more water. While on plastic it ... |
Why don't we have graduated brake lights? | Tail lights have two modes, either off or dim and I AM STOPPING. People rear end each other now when there are only two options.

how did we first assign money value to things and how does supply and demand change that? | I don't know that I can answer this well but I'll try.
