Why do computer programs sometimes slow down when they're open for long periods of time? | The simplest way to explain it is by thinking of a bucket you put water into. As long as the program is open, water is in the bucket. Whenevr you visit new information, you add water. Eventually you can't add more, and the bucket is very hard to carry. The only way to make it lighter is to close the program, or empty t... |
Why is there not/can we not have one 'super' programming language? | Programming languages are like tools. Some are like hammers, some are like drills, and some are like a saw.

Why do we see better at night if we block a light source from our vision? | Basically, your eyes are smart little organs. Our eyes only want to experience a certain intensity of light. Too much light and the eyes are overwhelmed, too little and the eyes are running below capacity. When there is a very intense light, the pupils of the eye close a little. That way, less light is let in the eye. ... |
Why can't cryptographic algorithms be reversedly used? | The functions used are inherently one way, meaning that there is no way to exactly determine what was used to get this result in the first place. An example for that kind of function is modulus: It is the remainder of a division. E.g. 15 / 10 = 1, remainder 5. So 15 mod 10 is 5. But there is an infinite number of numbe... |
Why my vote does or doesn't matter in the presidential elections | Most of the time you may feel like your vote doesn't matter.

why does wax make wicking material burn longer? | Wax is what's actually burning. Wick is there to keep the reaction going. Wax burns when it's mixed with air, so it first gets evaporated by a flame. Using the same principle you could make a candle from a piece of toilet paper and a stick of butter. [Video proof.] |
How can open sourced encryption algorithms be safe from hackers? (i.e. Bitcoin) | Knowing how something is done doesn't necessarily mean you can reverse it.

Why are the Republicans winning so many seats (in the both houses)?/ or why are the democrats losing them? | > it seems to me that the Republicans are on the wrong side of most issues when it comes to public opinion [That is not the case].

Why is gold and silver so valuable when it has very little practical use in everyday life? | it *does* have practical use. Plenty. Silver is one of the best conductors in the world and you often find silver suspensions used to help bind heatsinks to the heat-generating component. Gold is used in basically all electronics because it has extremely advantageous properties for connectors. Historically it's been so... |
How does fusion power work? | E=MC^2. When Hydrogen fuses to form Helium the Helium has a slightly smaller atomic mass than the two Hydrogen atoms combined did. This is true for every element up to Iron, that is Iron is the last result that has a net gain. This is called the binding energy, and it is equivalent to that formula. When you get enormou... |
Why does it matter if the population votes during a presidential election if the electoral college makes the final decision anyway? | The popular vote in a state determines how the electors vote. 48 states and Washington DC follow a winner take all model - a candidate who wins the popular vote gets all of that state's electoral votes.

Why does Google Chrome work great on some computers but is extremely clunky and buggy on others? | Google chrome takes up more ram then other browsers, but you shouldn't be experiencing that bad of problems, try using CCleaner or uninstalling additional extensions in chrome; if not try another browser, maybe firefox |
Who's in charge of coming up with street names and is there any approval by a committee? Also, if you were someone that decided street names how did you come up with them? | I am not sure how heavily it's enforced anymore, but I believe that here in New Zealand the type of road used to be dictated by features of the location, while the unique part at the start was up to the land owner.

How is a satellite able to transmit so many channels in HD/SD to so many TV dishes across the globe at once? | The number of dishes receiving it doesn't matter. Satellite TV is a broadcast system, it just sends the signal out for anyone with the right equipment to receive.

Why does 0! (zero factorial) equal 1? | n! = n! Using that, 1! = 1 *0!. Since 1! = 1, then 0! must equal 1. You can't keep going from there since ! would have to be infinite, but you might as well have zero be defined. And it makes combinatorics a lot easier, since they use factorials and you'd use 0! to calculate things like how many ways there are to arran... |
What is an alternate universe (or parallel universe) and how can there be infinite possibilities in one? | There is an alternate universe where you didn't choose to ask this question.

People are slamming unions and calling them bad. Why do so many people join them then? | From the worker's perspective, they're awesome.

since knowledge can only be past down from generation to generation through communitcation, how does evolution know when it needs to adapt to a change in the environment. | Say there are 5 kinds of mice. They are exactly the same except they are all different colors. A bunch of cats come along and they like to eat mice. They eat the blue, green, yellow, and orange mice, but for some reason they don't like to eat the red mice. That means that only the red mice survive. Those red mice have ... |
Why do librarians need to have a Masters degree? | Librarian positions are also **very** competitive. It's a government job that's very stable that's not labor intensive, and it pays well. Speaking from personal experience, pretty much everyone with an English degree who isn't a J. K. Rowling level famous writer, a teacher, or a professor wants to be a librarian. When ... |
Why do we need pubic hair? | I'm not sure about evolutionary advantage but pubic hair makes for a wonderful soap lathering staging point.No one really knows.

Why is adding acid to water safer than adding water to acid? Thinking of the rhyme "acid to water just like you oughtta, water to acid you might get blasted". | When an acidic solution is created, heat is produced.

why do republicans argue that Obama and liberal policies will destroy the economy when the NASDAQ is just shy of breaking a new record high? | The NASDAQ's performance has more to do with FED policy and the fact that we're in another bubble, and nothing that the President has/hasn't, done. And when you consider that Labor Force Participation is at the lowest it's been since the late '70s, and that the U-6 is still at 11%, I'm not sure that I'd start bragging ... |
In a game program, do bullets check if they hit an enemy or do enemies check if they are hit by a bullet? | there are two ways that games check if a bullet hits, the first is to have a bullet object that moves with physics, and then as it travels, the game checks if the bullet and the player's model are in the same place at the same time.

The cash register server knows that between midnight and 13:45:21, 18 cans of ... |
What can be done to make Sears brick and mortar stores live on? | Nothing really, expect a major brand overhaul. There really is nothing about Sears that's better than other stores/services. It's similar to why Macy's and Kmart are closing so many stores, even Sports Authority shut down. |
Why does it take hours to install big programs and games but seconds to uninstall it? | Just to add to the other good answers here: if it's taking literal hours to install something on a modern computer, then the installer is most likely downloading large portions of content/software from servers over the Internet, and this depends largely on your internet speed, and the speed of the software company's ho... |

Disclaimer: I am no expert. |

How does a computer get a mac address from an IP on larger networks? | _URL_0_ Review the top answer. On the local network segment, your PC is typically going to do ARP to figure out the MAC of the router acting as your gateway . Routers handle the traversal between network segments. At the destination, the target router will ARP to determine the target PC's MAC. In short, it works just l... |
Why is it acceptable to wait an hour to see a doctor when you have an appointment? | Well he's kind of a busy guy clearly something came up that took up more time than was planned. Unless you're bleeding out on the floor they are not inclined to hurry things along especially because being wrong is very expensive in this profession.So, I disagree with the people here saying "the doctor's busy, someone e... |

The same would be considered true for an egg, the day it hatches would be considered it's birthday.eggs are just a hard version of the soft "sack" babies grow in. Getting out of that sack is the mo... |
When a mammal gives birth to a litter, are all of the offspring "twins" i.e. have identical dna? | Twins aren't all identical, you know that right? Anyway, they are whatever plural number the litter is . They come from multiple fertile eggs inseminated by different sperm cells, and are thus not identical. Now, they can have identical litters. Some armadillos are renowned for doing it commonly. But otherwise it's pre... |

Are our hobbies and interests entirely a result of our upbringing, or are we predisposed to take pleasure from certain things? | I think it's a combination of both. We do inherit traits that predispose us to like certain hobbies or tasks and dislike others. For example, my Dad is a computer software engineer and I'm a web developer. Those traits that allow you to push other thoughts out of your mind while your troubleshooting something seems to ... |

What would happen if the stock market just stopped? | the stock market is the general name for the entire trade of shares of companies.

Coffee machines. Why can't you just put coffee grounds in a teabag? | You can. But coffee makers are mostly for people who want to make more than one cup & want to *have* it, rather than to *make* it. That's why coffee makers come with alarm clocks built in, so you can pre-load it the night before & it'll automatically make a few cups without you having to deal with it in the morning. Th... |
Why do we "freeze" in life-threatening situations? Shouldn't our bodies be doing the exact opposite in those moments? | Staying still might allow you to hide from a predator which hasn't spotted you. Immediately running isn't always the best plan. |
Can anonymous really do anything about global terrorism? | Not really, no. Like people have said, you can weaken them, you can take out leaders, find the root cause etc, however, whatever action you take, these groups will still exist, leaders will be replaced and they'll continue to do what they want as a REACTION to what we have done to them. It's a cycle of revenge, and it ... |
How do they digitally remaster old movies, and make them higher quality/ resolution? | Oops, you're correct. My mistake. I'm looking at the file size of a film I'm working right now.12,544kb for each .dpx file", 'Old movies weren't shot with old television sets in mind, but rather with big movie screens in mind. Typically for a theatrical film it will all be recorded on 35mm film stock which results in a... |
Why do so many medications have side effects way worse than what they're treating? | Most people don't experience all of the side effects, and they experience them to varying degrees over time. Depending on how debilitating their disease is, they can make the decision that the side effects are worth it or not. |
why do ADHD medications have the opposite effect on people who aren't prescribed them? | ADHD means you need more stimulation to 'lock on' to a topic. If it isn't new, changing, interactive and shaking you by the ears, your attention slides right off like a cat on slippery icy hill. You can scrabble all you want for purchase, but just can't dig in, and your brain skids somewhere else, rinse and repeat. It'... |
My Drivers license doesn't have a blood type on it, also i'm a donor. | As stated by others, I do not know of any area where the ambulances carry blood. I do know that some in Canada have a mini-lab thing that will test for your blood type to notify the hospital but I doubt those speed things up much more than an on-site test at the hospital. Think of it this way, in emergency situations t... |
If household electricity is AC, why do we use DC so much? | Up until the late 1950's just about everything in a house ran on AC. A lot of things still do. motors Light bulbs, heating elements . DC circuits are typically less than 24 volts while household AC circuits --a standard wall outlet is 120 volts and 15-20amps. In simple terms, more voltage/amps translates into more powe... |
When factories produce things like high amounts of carbon dioxide as a bi-product, why can't we chemistry them back into less harmful chemicals for the environment? | Well, think about oil for driving for instance. In that case, it's not that *we can't*, but think about why we're using it in the first place and what happens in that scenario. We're using oil to produce energy for a car to move. That means in order to reverse the reaction, we need lots of energy. _URL_0_ > All fuels h... |
How does HD TV work on old programmes? | Film was made to be shown on the biggest screen there is anyway so its not like.there's a lack of detail in the original prints. So providing you.have access to the originals there's little stopping you from making a good version for hd tvs. |
why do "a-list" actors seem to shy away from the horror genre? | Probably because horror movies are typically low-budget and thus couldn't afford to attract a-list talent. High-budget horror movies like *Shutter Island* can afford more expensive actors .Because "good" horror movies are called things like "psychological drama" and "supernatural thriller". Horror is almost always rese... |
How does our brain differentiate between sad music and happy music? | It has to deal with major and minor chords I believe. Major chords are pleasant and are sometimes called happy chords where as minor chords aren't as nice sounding so they are sometimes called sad chord. It has to deal with the intervals the notes are in. Disclaimer: I'm not a music major but I have some background wit... |
If the NSA has been shown to of have recorded many foreign exchanges of citizens (or politicians such as in Norway or Sweden) why hasn't the US been called out fiercely? | Much of the developed world has foreign intelligence programs of their own. It's very hard to seriously criticize the US when you are doing it yourself and when the US can cause serious problems for a country if you slight it. For other nations it really just becomes a question of what they can do? The UN isn't going t... |
why shouldn't i have made this post at the gas station from my phone? | They don't - Mythbusters tried *really hard* to make gasoline catch fire from a cellphone ringing. But safety regulations tend to err on the side of caution, and it takes a loooong time for those things to change. |
My washing machine has 4 sections: Perm Press, Heavy Duty, Knit and Delicate, and Pre-wash. What's the difference? | Just noticed my dryer has 4 modes: perm press, timed dry, knit/delicate and air dry. Are they any different? I don't think I've ever used anything except perm press. |
why don't restaurants take your credit card before serving food? | I'm not sure if you mean why don't they scan it through, it's because many point of sale systems don't store credit card information, so there is no way for them to swipe your card and then have it saved for later to charge your meal when you're finally finished.I would think it has mostly to do with the fact that the ... |
Why medical professionals, mainly nurses, on whom lives depend, are made to work 12 hour shifts? | As most people have already said, less shift change means less information that could possibly be lost. But honestly, 12 hour shifts aren't so bad. I work at a hospital, and I was recently switched back to 5 8-hour shifts from 3 12-hour shifts, and oh how I miss those long days. My job may not be as stressful as nursin... |
How come the US can spend almost $600Bn per year on military spending and not allocate a portion of that to eliminate at least homelessness, if not "below-the-line" poverty alltogether? | Because you can't eliminate poverty and homelessness just by spending money. If you are mentally ill, have a drug problem, a gambling problem, or just live in a neighborhood overrun with crime, just giving people money doesn't help, and can often make things worse. Eliminating poverty is about economic development and ... |
Why do big vehicles like buses and freightliners have flat front, while smaller cars (and some freightliners too!) have longer and wedge-formed front? | Trucks used to always have a wedge shaped front. The flat front was developed to skirt around length restrictions which existed in some countries, allowing for heavier trucks without making them any longer. So they moved the engine underneath the driver's cab. The increased drag from this isn't such a big deal due to t... |
Why don't NASCARs have treads on their tires? | No, on a flat surface the best grip is the most contact area. You get that by not having grooves. If rain were involved you would want grooves to allow the water to have a place to go, but they don't race in the rain. |
How are bees attracted to a beekeeper's artificial hive? Do they find the space accidentally? Or do you use something to attract them? | You actually buy bees usually through the mail and they arrive alive, with a queen.

If you need to, you can use a bit of sugar water or queen pheromone to tempt them in.Bees are attracted to the sent of their queen. The beekeeper has a small ... |
Is there an advantage to parking diagonally compared to vertically? | Well, parking vertically is pretty challenging. Getting the car perfectly balanced on it's back bumper, not doing paint damage, then being able to get out is quite a challenge. Pretty much any way to park is better than parking vertically. That's why you never see a vertical parking lot. It would save a lot of space, b... |
Why do some towns still use fire whistles to alert emergency workers when we have cellphones, beepers and radios? | Also, adding to /u/Phage0070's explanation, fire whistles are also relatively easy to use, and are reliable. |
How can the dollar be "too" strong and how does it negatively impact the U.S? | It has to do with exchange rates. Let's pretend we are selling Cars manufactured in the U.S. to Mexico for $100. If the 1 Peso = $1 the car costs 100 Pesos for a Mexican. If the dollar is strong it means 2 Pesos = $1 . So now it costs 200 Pesos for our Mexican friend. Unfortunately they don't get a raise so they can't ... |
How are we able to determine things such as wind speeds and temperatures on planets outside of our solar system? | You might be interested in asking this on /r/askscience for a slightly more detailed explanation. To elaborate a bit on what was mentioned by /u/III_Cloud_III; We can take a guess as a planet's temperature based on its distance from its host star and the star's temperature. This would have to be augmented by knowledge ... |
Time perception. Do different people perceive time differently or is that even possible. What affects our time perception in life. | Think of it like this compare how long 1 hour feels if you are busy doing something you enjoy vs. how long it feels if you're just bored/waiting for the hour to pass? The actual time doesn't change but your *perception* of the time changes. There's no reason why someone who is regularly bored/regularly busy perceives t... |
