Why did Ted Cruz ask those students to text "Constitution" to 33733? | It's a way for his campaign to identify potential supporters. Presumably people who text back are those who are both interested in politics and potential supporters of his. It's good to identify and engage with those people early. They are more likely to vote, more likely to donate money, and more likely to get others ... |
Once and for all, is The Pirate Bay legal, and if it isn't how does it remain online? | There is no global law covering The Pirate Bay and similar sites. Even if, for example, it's illegal in the USA, it might be legal in Sweden. If there is even a single country where it is legal, it can be hosted in and operated from said country, and then there is no mechanism to take it offline entirely. As for whethe... |
What's currently happening on Brazil? | A couple things, really. The President and many members of the government are in deep trouble for something involving Petrobras — they are accused of taking bribes, etc. and this issue specifically is very divisive so I won't take a side. Then there's the fact that they have really bad economic problems, and they still... |
- Why when people sneeze it’s out of their mouth, but your body is trying to get something out of your nose? | I've wondered about that too. I think it has something to do with your nasal passages not being able to handle such a big blast of air, so most of it has to come from our mouths. Maybe sneezes aren't meant to get something out of our nose as much as they're meant to protect the more vital parts of our respiratory syste... |
Now that net neutrality rules go into effect today, how does that affect the average person? | It's still being argued in court. The only real effect of the change is the structure of the court arguments shifted to one that enables more government regulation of fairness. The average person won't know the effects until the court cases shake out, give it 2-3 years and ask again. Sorry, the world of government regu... |
- Could we only eat exactly what our bodies need, and never poop? | > Poop is just waste, right? Wrong. Or at least, poop is not just undigested food. Feces contain various other biological waste products that we can't stop producing. Things like bile, and broken-down, dead red blood cells. Plus, roughly 40% of feces consist of dead bacteria: You have **tons** of bacteria living in you... |
Reddit has made Bernie Sanders look like the perfect candidate. Can someone explain some of his generally negative views? | He is anti-science..

Additionally, he has sponsored a bill to treat veterans with "alternate" medicine rather than scientificall... |
What is cardiovascular endurance, what happens within your body when you gain it, and what happens when you lose it. | Cardiovascular endurance refers to how efficiently your cardiovascular system can absorb oxygen and deliver it to tissues throughout the body. When you "gain" endurance, you're just working out the heart like any other muscle. Instead of lifting weights, you're running, walking, cycling, and anything else that is consi... |
How do scuba divers ascend/descend? | They wear a device called a BC . Usually it is a sort of vest with an inflatable bladder inside. Air from the tanks is redirected to the bladder to make the diver more buoyant, and released to make them less. Divers also typically wear weights to ensure they can sink if necessary, and that be released in an emergency. |
When markets crash, where does all the money go? | It was never there to begin with. Say Jon has 50 shares in Company inc.. On the market, these 50 shares are worth $500, because lots of people want to pay $10 for a share in Company inc. But Jon doesn't have $500. Jon has 50 shares. Suddenly, news breaks that the CEO of Company inc. makes all of her major business deci... |
Can someone explain to me what's the issue with Obama and drone strikes? And why what he said in Prague about nuclear weapons is so frowned upon? | I don't know much about the topic, but one of the issues with drone strikes is that how we classify the victims of the strikes is woefully inadequate and misleading: _URL_3URL_2URL_1_ Essentially, Obama changed the definition of "militant" in drone strikes to be incredibly wide to the point where if you or I were there... |
Why certain factions of Israel's leadership believe that settlements are necessary for Israeli safety. | If you stand in parts of the settlements, known as Judea & Samaria, you can look over Israel completely and see the sea. If the Israelis don't have access to the settlements, then their enemies could easily fire down on the Israeli population. So it's a security issue for many. |
The different Dimensions relative to our own. | Don't let anybody fool you into thinking this is more complicated than it is. The word "dimension" simply refers to a number you use to identify a point. Here we 've got a straight line. How can I pick a point on that line, then give you sufficient information to find exactly the same point? Well, we'll start by agreei... |
in Great Britain, what does the power differential look like between the Monarchy, Parliament, and the Prime Minister? | The Monarch has, in effect, no legal power at all. In theory they can withhold their Royal Assent to a law, but in practice if they did so it would make the abolition of the monarchy much more likely, so they don't. Any stated political positions of the monarch would probably have significant impact one way or another,... |
How this battery train experiment works? | [This] should help you out people on a physics forum explaining it pretty simply EDIT: Aww hell, I guess I'll copy/paste the answer here > If you run a current through a coil; it generates an magnetic field inside the coil [like this] > If the field lines are exactly parallel a bar magnet will feel no net force. Howeve... |
What exactly are TOPS for college. | TOPS is a program in Louisiana that offers free college tuition to students who meet a certain GPA and ACT requirement.

What is the difference between an irrational number and a transcendental number? | > All transcendental numbers are irrational. not all irrational numbers are transcendental. > Trancendental numbers cannot be written as roots of polynomials Eli6: Irrational numbers are a class of numbers that are defined by the fact that you cannot represent them as a ratio of integers. Transcendental numbers are a c... |
Why does it burn if you burp through your nose after drinking something carbonated? | They contain small amounts of carbonic acid and there will be some of this left in the gas that you release. Your nose is far more sensitive to such things than your mouth is, so you feel the acid burning more than your mouth. You can test this with a green chili. Place one on your tongue and place one up your nose and... |
Why are GPU clock speeds soo much lower than CPU clock speeds. | They have very different architectures and are built for different purposes. Generally, GPU clocks are set as high as it is viable as well but asking why they are at such different levels is more or less like asking why bike engines and tractors operate at such different RPM. They might be slower, but not exactly "wors... |
How is the TV rating calculated? | They don't. They use sampling of a select few and project that out to the whole population. They will often use [Nielsen Ratings] which will connect a device to a television to record their viewing habits.TV ratings, the way they are done now, are statistical extrapolations based on representative limited user groups. ... |
If a US soldier dies in another country and he is a donor, will his/her organs be donated or discarded? | Yes, if viable the persons organs can/are be donated. However I did some googling and I found that it's pretty unlikely the organs can reach the patient in time. The heart is viable for 4-6 hours if kept on ice, with the liver ideally no longer than 12 but viable for up to 16 hours. The organs would never make it back ... |
How to temperature guns work in order to get the temperature of a surface? | Next time you turn on your stove, you might notice that the burner turns red as it heats up. That's because increasing the temperature of an object causes it to radiate energy. Now, for most objects, increasing the temperature of an object over the comfortable range for human beings doesn't change the energy it emits a... |
How come I'm well-rested after sleeping from 3 to 12, but when I fall asleep at 12 and wake up at 9, I feel like hell? | You can read up on Circadian Rhythm and REM Cycles for a more detailed explanation, but the simple answer is the your body gets used to a certain sleep wake cycle based on your habits and environment. When that cycle gets broken, by going to sleep too early or too late, or sleeping to long or to little, it can cause fa... |
How Google stores caches of so many websites | There are a few methods that Google uses. The primary one is that Google spends plenty on continually adding more servers, server space, and improving their ability to manage that ever-growing space. Also, copies of crawled websites compress better than many types of data. Google once released that they're able to comp... |
Why is it bad that Rachel Dolezal identifies as black even though she's apparently white? | The thing about race is that there's virtually no difference in brain chemistry or anything like that between races. Identifying as a different gender, for instance, is different, where actual physiological differences might come into play. Race identification is a very superficial thing, genetically, and plays more in... |
The difference in natural sugar you find in fruit and refined sugar? | There is no chemical difference. When you eat fruit, you're eating sugar embedded in a plant, and so you digest it more slowly , and you take in all the other stuff in the plant .

how every lock and key in the world is made to be unique with no duplicates | They aren't, there are lots of duplicates out there Schlage house locks are very common, their keys come with a 5 or 6 digit code on them. Best case that gives you a million key combos. Not nearly enough to make every lock unique, but plenty to make it unlikely a random person has the same key as you Security is design... |
What happens if the CA drought continues and we run out of water? | In the event that the drought continues, water will be re-prioritized for human consumption [Irrigation of Agricultural Crops - Department of Land, Air, and Water Resources].

ETMLI5 why churches/religious buildings in the United States get property tax exemptions? | religious institutions are not-for-profit 501c institutions, just like the YMCA or Duck's Unlimited or other non-profits. a nonprofit's income and profit is legally supposed to go toward the betterment of the organization's mission or the general benefit of the community. the profit can't go for bonuses for employees o... |
Why is third party software "locked" to certain operating systems? | The operating system, among other things, provides an interface for programs to the hardware and usually other stuff like the means to make a window, put buttons in it, render things, etc. There's no cross-platform interface for all this that exists natively on all OSes except kind of ChromeOS and FirefoxOS which are b... |
what were the negative social and economic consequences of bigamy/polygamy, that gradually resulted in its criminalization, in most countries ? | You can look at it from both directions. In one direction, polygamy is a response to a shortage of men. Normally, this shortage is due to consuming those men in wars and violent criminal enterprises. So extremely violent societies are more likely to favor polygamy. In the other direction, polygamy causes the violence b... |
Why do people want Obama impeached over the Benghazi attack? | The scandal originally was about when the attacks occurred the Administration, including Hillary Clinton, blamed it on reaction to some terribly made [anti-Muslim movie trailer].

After the apocalypse, how would I start a currency for my newly created society of 50 people? | Something everyone needs, so perhaps bullets, or rations. Examples would be The Last of Us and FTL: Faster Than Light. Both these games, one being post-apocalyptic, the other a space exploration thingy feature trading using ration cards and "scrap" respectively. Both of which have a face value that is of a wordly use, ... |
Why can you only use a #2 pencil on a scantron sheet? | It's not really an issue of whether it works, but of who is responsible in the event that it doesn't work. They aren't going to test their machine with every possible type of pencil. Even if they tested it with a variety, *someone* would find *some* pencil that doesn't scan right. So instead, they test it with the most... |
Why are there no sentient plant-based species? Why is base intelligence so abundant and diverse in animals, but non-existent in the plant kingdom? | > Is there something inherent to “plant cells” that prohibits that possibility? It is more something inherent to plant biology that prohibits the possibility, and is related to the lack of nerves within plants. Brains require *a lot* of energy! The human brain consumes about 20% of the total energy used by the human bo... |
aliasing and antialiasing in computer graphics. | Game's graphics sometimes appear to be "pointy" or not curved enough due to the way the objects are built - using a grid of dots/ geometrical shapes and covering them with a skin/texture. antialiasing process adds "new dots" to the object in order to smooth its appearance.Your computer screen is made up of 'small squar... |
how does a traffic start on a highway? | Let's say that a road is full of cars going the same speed. Something happens that causes a group of cars to slow down. All of the cars behind them have to slow down, the cars behind that set of cars, and so on. Long after the original cars have sped up and gone, cars far away are still having to slow down due to that ... |
Why does chicken pox get more dangerous the older you are? | The chicken pox virus isn't completely understood, but it's thought that it's harder on you as an adult because your body attacks it more violently. In other words, it's worse not because the virus is worse, it's because your more mature immune system reacts more strongly to it and causes other adverse affects. |
How would "true" Communism work? | As in the ideal? There wouldn't be a concept of ownership. Everything would in some way belong to everybody.

This obvious... |
If there is no sound in space, how is that car broadcasting Bowie up there? Is it able to be heard if you were near? | Actually were there are molecules there will be sound. If the Tesla passes through a cloud of gas you could in theory hear it, until it passes out of the cloud. The music will always be playing and if you place your head or for that matter your hand on the car you will feel / hear the music with vibration through the c... |
Why do so many fast food drive thrus have 2 windows, but always have you pull to the second window? | The reason for this is that if they get very busy, they can have you pay at the first window and receive you food at the second. However if they do not feel they are busy enough to merit the extra worker, they will only have 1 window open. I believe they typically use the 2nd because it is closer to the kitchen and fro... |
How misted water and sunlight make a rainbow? | Here's a pretty simple phenomenon to explain. Sunlight, is composed of many different wavelengths of light sandwiched together. Some of this light isn't even visible to human eyes, however those colors which we can see are part of the visible spectrum: red, orange, yellow, green, blue, and violet and all of the colors ... |
If I set my portable A/C to 20°C when the room temperature is 10°C why/why won't the A/C heat the room? | If you want to use the AC to heat a room, you need to reverse the outputs: The radiator that gets rid of the heat needs to vent inside, and the radiator that produces cool air needs to vent outside. However, even if you do this, the temperature controller might not consider that application, so you would have to set th... |
how do people die in their sleep in a fire? Wouldn't uncontrolable coughing wake you up first? | The carbon monoxide gas can knock a person unconscious -- so they may be "put to sleep" before they ever wake upMost people who die in fires die from the lack of oxygen and the carbon monoxide. The process is gradual and you go from sleeping to loss of consciousness to death without noticing. You may get some coughing ... |

if a murder were to occur on the ISS, what would be done about it? | [Wikipedia article on space jurisdiction]. [PDF on law in ISS]. [More info]There is probably no set routine for dealing with space murders, as it is such an unlikely and unheard of event. Most likely, it would be a special case, and the country of origin of the murderer would prosecute them due to pressure from the cou... |
What caused the "Dust Bowl" of the 1930s? What stopped it? Could it happen again? | Cause: Excessive farming. The area that the Dust Bowl took place in had spent centuries/millenia/etc. with grass holding down its dirt against winds in the area. Settlers went west and plowed everything up, and the wind started picking up the dirt. Stop: Mostly people realizing that over-farming was bad, as well as the... |
Why do escalators break so easily and why does it take so long to repair them? | Escalators have a hard life. A lot of the time, they are very old, I know some in my city are apparently upwards of 50 years old. They are always in use, always being walked on with wet, muddy shoes and get full of dust and debris. With something so big, they have to decide whether it is worth replacing or repairing. A... |
Why are kids so fucking picky? | Firstly, kids have a stronger sense of smell and taste. Many of the things we eat can taste and smell much stronger to kids. Secondly, kids have a phase when they realize they can refuse things. They realize they can say "no", that they are not mindless subordinate to adults. They learn that they can express they do no... |
(biochemistry) why does Km decrease for uncompetitive inhibitors? | Uncompetitive Inhibition occurs when an inhibitor can only bind the enzyme-substrate complex. That is, free enzyme is not a target of inhibition, but once a substrate enters so too can the inhibitor. Obviously, because enzymes which are bound to substrates can become blocked, the Vmax must be reduced. Km, however does ... |
Why can I use headphones as a microphone and not a microphone as a speaker(s)? | You can if the mic is a dynamic mic. Most mics are electret condenser mics. If you do try to use a dynamic mic as a speaker, you will get very little sound and will burn out the coil if you try to get more sound. Microphones are made with thin wires and small diaphragms. |
Why do people twitch, or jump, while they are falling asleep? | Ah I hate these! It's a called a hypnagogic jerk and they occur during the transition between being awake and asleep. There are a couple of theories for them, such as accidental neuron misfiring, but I like the evolutionary approach to the phenomena. The theory goes that the jerk originates from our origins - when we m... |
When reading nutritional information labels what is the remaining weight made of? | Water it is. There is pretty much nothing else that could possibly be it. A very small percentage would be some technological additives like preservatives, colourants and stuff, but they usually are used in insignificant amounts . Oh and possibly air if you think about some puffy bread, but that too is absolutely insig... |
How does wind 'suck' a door shut? | Venturi effect. Air flowing through a restriction--even if only restricted on one side, such as when it flows past your open garage door--creates a low-pressure area as it must flow faster to get past the restriction. Higher pressure air inside the house then blows the door at the top of the stairs shut. The Venturi ef... |
Can someone explain why is it when you crouch down, take deep breaths and quickly stand up, you get dizzy? | Hyperventilating [reduces the level of carbon dioxide in the blood]. Rising carbon dioxide levels signal to the brain that you need to breathe - hyperventilating before hand allows oxygen levels to fall further before this happens. This is explained on [this wikipedia page]. Standing up rapidly reduces the amount of bl... |
What causes someone's voice to sound so much different than the norm (i.e. Gilbert Gottfried, Ray Romano) ? Is there a distinct physical difference in those people's larynges? | No idea. I was curious too. but I do know Gilbert Gottfrieds voice is fake. he's over the top on purpose. _URL_0_ |
The process for writing a song | This has more to do with lyrics or stories or just writing in general but I think Neil Gaiman sums it up very well in my opinion. "You write. That’s the hard bit that nobody sees. You write on the good days and you write on the lousy days. Like a shark, you have to keep moving forward or you die. Writing may or may not... |
Where does the $$ for universal basic income come from? If an entire country is making UBI, where do the tax dollars come from? | So the issue here is that people are still going to have jobs and work in companies. Many people are still going to work because they enjoy their jobs, because they want to have more money beyond the UBI, because it will keep them busy. The idea is that enough people will still be working that the economy will function... |
Why is pork belly not being sold more commonly in the US? | Pork belly is sold in the US, but people rarely buy a slab of meat. They prefer to buy it already processed into cuts, so they buy primarily bacon and to a lesser degree fatback rather than buying full porkbelly.It's becoming one of those trendy foods. More and more restaurants have it on the menu. Arby's has a pork be... |
What would happen if very few people voted in the US 2016 Presidential Election ( E.g < 10 million votes) maybe as a protest. Would this open other options after the election? | State law decides how the states use their electors in the college. The states choose to determine their vote using a popular election, but I'm not aware of any state that requires a minimum turnout. Perhaps they would retroactively implement one in the event of extraordinarily low turnout or a dubious election; an opt... |
How is the 9th circuit court's decision on concealed carry today reasonable? | The First Amendment guarantees the right to free speech, but you can get in trouble for inciting hate crimes, yelling "I HAVE A BOMB!!!" on an airplane, etc. There are reasonable restrictions to the right to free speech. "right to keep and bear arms shall not be infringed" does NOT MEAN "there can be absolutely zero ru... |
what a vector in terms of art is? | I think you mean vector graphics. Right? It's just a way to save image files. Basically when you save an image using a vector graphics you save the mathematical equations that produced that image. The advantages are: high resolution , you can modify the image without loosing quality, you can compress the image without ... |
Why is it that you wake up sick but don’t get sick while awake? | I’ve developed a cold throughout the day twice. I know when it happens now because I become really really thirsty and just feel tired on the afternoon. The sniffles start soon afterIt's actually the opposite. When you get sick, the stuff you are feeling isn't actually the result of the virus. What you are feeling is yo... |
When the concentration camps in Nazi Germany were liberated, why were people from local towns forced to bury the dead? | It was because the soldiers liberating the camps were angry. Angry in a way that they had never been angry before, gut-wrenchingly furious. Wanting to lash out in some way. They did it because they believed that if the German civilians knew about or not it then this would bring it home to them. Might be right, might no... |
How do earplugs that block mostly loud sounds selectively (gunshots) work? | If you're asking about the style I think you are, they have a microphone and speaker assembly mounted in an otherwise high-reduction set of earmuffs. The mic and speaker are set up to run normally until a certain decibel threshold is reached, at which point the microphone cuts off and you are effectively on mute until ... |
Why do some people have nightmares/bad dreams after eating spicy foods? | Spicy foods can cause indigestion while you're sleeping. Stomach pain is commonly associated with fear or anxiety, sending your brain the signal that something is wrong. Because you are asleep your brain takes that anxious feeling and attaches a reason to it creating the narrative in your nightmares. |
Why does peppermint unblock sinuses? | Menthol and related molecules activate thermoreceptors responding to cold. One of the physiological response to cold is vasoconstriction . When your nose is blocked, it is mostly due to those vessels that are dilated, therefore, menthol can reduce that blocking since it will contract them. |
Why does it feel good to stretch out on the floor or in bed in the morning? | Your muscles are held in their shape and place by a filmy covering called "fascia". As you sleep or remain motionless the fascia can grow and restrict muscle movement. A good stretch in the morning moves your muscles and the movement brushes away the fascia growth in the night. And you will feel free and looser. Its al... |
Why dogs act like they're swimming when they're being held above a body of water. | Most animals have instincts that aren't 'perfect', including humans. These imperfect instincts can react at the wrong time if the animal is in a situation that, evolutionary, it would have needed to react in. So a dog knows it's above water and it starts swimming, because evolutionary when a dog was above water it was ... |
If everyone uses a form of AD Block Plus how will, Twitcher/Youtuber/Web sites make money? | If they can't show you Ads, they can't make money but less than 10% of those sites' population uses an Ad-blocking pugin/extension, so they don't worry yet. While that percentage keeps shy, big sites won't take action but if everyone uses Adblock or things like that, the sites will start banning people who uses them. |
What is the difference between 32 bit and 64 bit windows? | Differences in programming. Why? Because there are different kinds of CPUs, 32 bit and 64 bit. The primary difference between 32 bit and 64 bit CPUs is the way they index RAM. RAM is used for temporary storage for the CPU when programs run so that the CPU can have quick access to them as opposed to waiting on a drastic... |
Why are so many scotches named "Glen-"? | Glen means "valley" in gaelic. Scotland is reasonably hilly, and thus there are a lot of glens . Many glens were given names: Glencoe, Rutherglen, etc. And just like in every country, a lot of things/products/regions in Scotland are named for their location . Finally, and most importantly, "glen" has a pleasant sound t... |
ELI-Five me Google's new privacy policy taking effect on March 1st, 2012, and what parts of it I should make note of, and/or be concerned about? | First of all, this has been asked [several times in this subreddit] already. Second, because I'm such a nice guy, here's an easy-to-understand explanation from the Electronic Frontier Foundation: _URL_1_ |
The short and long term effects of the airplanes dumping fuel have on the atmosphere, the soil, and on water. | What happens is that it drops down below. There are regulations; fuel dumping is only done in emergency situations, where landing with all that fuel could be dangerous. It's not a huge problem, since it doesn't happen often. Not only are the airlines not permitted to do it, they aren't inclined to do it unless they hav... |
How is Reddit still "unprofitable" if the average daily reddit gold goal is 100%? | I thought the whole point of reddit gold was to pay for the servers, not to profit. I thought the daily goal was equal to the daily cost of running reddit servers. Am I wrong?', "To many companies, technology companies in particular, users are much more valuable than profit, since the profit on *today's* user base is m... |
Why is it hard to remember dreams? | It is difficult to remember dreams, because dreams take place in the brains pre-frontal cortex whereas memories and movements are stored in the cerebral cortex. Lucid dreams occur when our dreams drift into our cerebral cortex. This is the kind of thing that you learn in Neurology 101! Fox, Mason T. "Christopher A. Wal... |
Why perfectionism is a negative trait? What's difference between perfectionism and doing someone's best? | [This xkcd comic puts it pretty well.] Or, there's the saying "Don't hold a $1000 meeting to solve a $100 problem." In many situations, there's no approach that is objectively the "best" solution. Let's say I have a job interview, and I want to look my best. I put on a blazer, slacks, nice shirt and a tie. Red tie or b... |
Why can't you remember the exact moment you fall asleep? | We don't yet fully understand how memory works, or how sleep works, so any answer to this question is going to be making assumptions. But we do know a few things: 1. When you are sleeping, your brain does not form memories in teh same way as it does when you are awake. 2. Memories are not immediate - there is a delay a... |
What is going on with the California drought? | California hasn't been getting enough rain. The first year, everyone was thinking this was a short term problem and would resolve itself. The third year water reserves are growing low and there's serious concern that if things don't change, California won't have enough water to not only continue with industrial agricul... |
How does a magnetic core, like Earth's, form? I have a very rudimentary understanding of how planets form. But, how did the Earths core end up like it is now? | Earth's magnetic field comes from the molten outer core. When our sun was young, leftover gas and dust from it's formation orbited around it in a disc. clumps of this gas and dust started to swirl together to form the planets. The denser elements like iron and nickel fall to the center where under immense pressure and ... |
Why dont we build cars using water electrolysis? | It takes more power to electrolyze water than we can recover from burning it.Any energy that is released when you combine two things, must have been put into the two things in order to separate them in the first place. . |
Security Certificates (root, wildcard, etc) | Certificates are cryptographically signed electronic documents that are generated and released by "certificate authorities". The certificate authority is an organization that says "Okay, we're going to issue all of these certificates. We trust them to be who they say they are. Therefore if you trust us, you implicitly ... |
Why is wheat now mostly grown in temperate and cold-winter regions when it came from the fertile crescent? | Two reasons: * In the Fertile Crescent, wild wheat relatives grow over winter, flower in late winter . As it evolved to deal with the cold winter nights of the Fertile Crescent, which made it very adaptable to the cold, more so than many other grains *, it can be grown in cold regions where other grains don't do well. ... |
What do the sanctions against Kim Jong Un mean? How can you sanction a physical person/country leader? | The US maintains a big list full of people you can't do business with. You can see it right here : _URL_0_ Part of my job at the company I work for is to go through this list and make sure that none of the people we do business with is on this list. Of course, the government isn't watching you all the time so it's your... |

The brighter the fangs, the "bigger" they appear.Edit: Talking ^out ^^my ^^^ass. ^^^Evolved ^^^that ^... |
Why does a GPS tracker require a monthly fee/service to "connect," but a GPS car navigator (e.g. Garmin) does not? | So GPS is a completely passive technology. A GPS receiver listens to signals broadcast by a group of satellites at known locations, and uses the timing difference between those signals to calculate its own location relative to the satellites. But the end result is that *only the GPS receiver knows its location*. The sa... |
When you throw a ball in a parabola, does it actually trace a parabola? | A parabola is what you get in the idealised case where the force of gravity is a constant. This is a good aproximation for movement near Earth's surface, 13,000km from the planet's centre. In your case, though, gravity is nowhere near a constant, so the parabola becomes an ellipse. |
What if we had different math. Would we understand the world? | Nothing about the fact we use base 10 affects how scientists, economists, or other experts understand the universe. They just need *some* way to write down numbers. In most of their work, the actual numbers don't even show up until the end -- the important work is in describing how one factor relates to another, and th... |
What causes us to be mesmerized by fractals and certain repeating images, such as in a .gif? | Our brains are logic machines, similar to computers. Our brain takes in large amounts of data every second and has to make sense of it all. To do this, the brain looks for patterns that can quickly process the data into something recognizable. It why we prefer symmetry in everything . So, anytime we see repeatable, pre... |
How does purchasing goods from across the world work? | You have to trust the indian that he will send the goods, just like you trust _URL_0_ will send the goods after you give them your CC info. If the indian wants to sell to international buyers, he will have a bank account setup to accept foreign money . |
The difference between classful and classless routing protocols. | **TL;DR: Classful routing protocols do not take the subnet mask into consideration when routing packets. Classless routing protocols do and allow subnetting.** This is a pretty good question. I will try and explain it to the best of my ability. Let's look at 2 routing protocols. RIP and RIPv2. RIP is a classful routing... |
Why, after an emotionally taxing event such as a tough breakup or loss in the family, do people not experience hunger for a while? | When at rest and not in danger, the body is in what is called the parasympathetic system. Also known as the "rest and digest" phase, this is the time where the body will build new cells and absorb as much energy as possible from food. When in danger, the body goes into fight or flight, or the the sympathetic system. Th... |
The relationship between thunder and lightning | Lightning is very hot, and quickly heats up the air right next to it around 35,000°F . Heating up the air this quickly causes it to expand really fast, creating a sonic boom. It's the same process that happens when a firecracker going off, but on a much larger scale.In addition to what gullinbursti and dreamzchaser sai... |
How would you explain the Trinity? How can God and Jesus be different and the same. | Not a Christian anymore, but I went to a private christian school throughout all of highschool, so I hope those mandatory Jesus classes taught me something. Jesus is the Son of God because he was given birth to on Earth. He lived his life as a human and even died. This humanity factor makes him separate from God, a uni... |
How are people/groups of people legally allowed to place "bounties" on others? | They're not "bounties" like in the Boba Fett sense. They're rewards to turn over information which would lead to arrest/prosecution. Boba Fett bounties are illegal. |

Myanmar has recently taken steps towards becoming more democratic, and releasing government control over the economy. An American President visiting Myanmar shows the p... |
How can rain fall at different speeds? | Larger raindrops have higher terminal velocity than smaller raindrops due to mass increasing disproportionately with respect to the cross-section presented to the atmosphere in the "down" direction. |
Why does hot water rise and cold water sinks but ice floats? | Ice is less dense than water, due to a quirk of its molecular structure. When water freezes its molecules form ring structures, increasing the volume without increasing the total mass. This reduces density, and since objects less dense then the liquid they're in float, ice floats.Cold water is denser than warm which is... |
How does esp and other sport networks come up with these obscure stats? | They have computer programs that do it. All the stats are recorded and maintained by either the league or the media themselves , so the data is all there. It's just a question of writing a computer program that pieces together stats out of that data, which isn't that hard to do: computers don't mind just combing throug... |
