How does it make sense that I get 100 ms ping on New York servers from the west coast but I get 150 ms on London servers even though it's twice the distance away? | Latency has more to do with the number of hops the information has to make than it does the total distance. So: > LA - Chicago - NYC Isn't really significantly different than say: > LA - Chicago - NYC - London If there aren't too many added hops between NY and the UK then you won't see too big a jump in latency. |
How are underwater tunnels made without flooding and killing the workers? | They don't build the tunnel through the water, they dig *under* the rock that's under the water. [Here is a diagram] so you can see what it looks like. |
How does Stephen Hawking's speech translator work? | He uses a muscle in his cheek to move a pointer and select words on a screen. If he has a long speech, he prepares it in advance, because this is not a quick processNot sure when he became able to move a "pointer and select". Usually it was a scrolling selection. He has words in categories. I am sure far more complex t... |
EL15: Why do I automatically fear for my safety when a group of strangers on the street is laughing? | It's probably down to projection of dominance of a wider than normal area. Group of guys chatting, just walk past with usual personal space distances. Add laughter and it asserts that they feel a much wider area is their personal space that they feel comfortable in, therefore, when you walk past you are entering their ... |
Why are ears shaped the way they are? | Mostly just because natural selection doesn't select for specific or perfect features, just for what works.Ahoy, matey! Yer not alone in askin\', and kind strangers have explained: 1. [ELI5: Why are our ears shaped so wierd? ]1. [ELI5: Why are our ears shaped the way they are? Why dont we just have a simple hole? ]1. [... |
Why are some videos on YouTube 1-2 hours long and others are broken into 10 minute increments? | I believe it used to be the case that you could only upload 10 min. long videos unless you were an "advanced" youtuber that e.g. had a substantial number of subscribers or high quality content. Some educational videos purposely make their videos 10 min. long to enforce a "break" between videos as to not put too much st... |
Why does each house have a different smell? | Every person smells different, they use different things, different cologne or deo , different detergent, they cook different things in a different way. It's the same for houses. The people who life their make the smell of the house. If the house is full of carnivores who often like to cook their bacon with closed wind... |
Why is it such a big deal to require voters to provide photo ID when it is expected for other daily tasks? | There are lots of people for whom this is not true and for whom getting an ID is really not as trivial as it probably sounds to you. Do you think getting an ID is easy if you are: old, sick, physically disabled, without a mode of transportation, homeless, or living far from a photo center? Voter ID is also seen as the ... |
Why is it so difficult to create a true "chrome finish" for home craft projects? | The process of painting something is not like electroplating. When you try to paint anything chrome, you are putting a layer of material over an object. Think like plastic wrap. Plating metal with chrome is a process that actually uses chrominum to form a bond with the material with electric current. Its a totally diff... |
Why can be build custom PCs but not custom phones? | Phone makers work so hard to make them ultra compact, that there is no spare room for extra components or even for removable plugs.> Is it something to do with welding/gluing the parts in a phone instead of clicking them into place like a PC? Pretty much. PC's mostly use standard connectors and sizes for parts, so they... |
Why do I feel full way down in my gut after eating a big meal when the stomach isn't that far down? | You have nerves in your abdominal cavity that are sensitive to pressure. Gravity is pulling your stomach down and more pressure nerves under your stomach are getting triggered than the ones above it. |
Why are people scared of bugs? | There's likely a genetic component. Natural selection might have favored humans who stayed away from poisonous insects, even to the point of fear. Of course, it's not a pure benefit--some insects make pretty good food. The environmental influence probably involves both direct experience with insects and seeing other fe... |
why do I sweat so easily and more profusely than others? | People who are in shape sweat more and more easily than people who are not in shape/not used to physical exertion. Don't be embarrassed, just realize it's because you're a better physical specimen than most people are. But don't be narcissistic about it.Hyperhidrosis. Overactive sweat glands. I have that shit as well. |
What is the difference between a customer and a client? | A customer is a person that buys stuff or services off you, so you are pretty much in charge. A client is a person that hires you to solve their problems, so they are in charge.Colloquially, they're pretty interchangeable but formally I believe a client is a patron who is receiving a service while a customer is a patro... |
How did Islam become so subject to extremism? | > I mean, you don't exactly see, or at least hear about, many Christian, Buddhist, or Hindi suicide bombers. How did this come to be? It came to be, because we don't report everything equally. Things that are more pertinent, or more engaging to an American/Western audience get top billing. Consider [here] [here] [here] |
If my domestic water pressure is 20 psi, and I install a 20 psi water pump on the mains, will the resulting pressure be 20 psi or 40 psi and why? | It depends on the pump, since it might *try* to increase the pressure from 20 psi to 40 psi, but fail to do so for some practical reason e.g. inability to handle 40 psi. I have seen camper pumps that have pressure switches to detect when the inlet is pressurised past a certain point, implying that it changes the pump's... |
atoms combine to make completely different substances? | Chemical properties are all about what shape they are and what they bond with. Sodium isn't very happy alone. it has an electron it really wants to get rid of. So like a horny teenager it will bond with whatever it can, like water, causing explosions. In the meantime it's all metallic and stuff. Chlorine also, is not v... |
What does "Purchasing Power Parity" mean? | Purchasing Power Parity basically means how much can you buy. So using that Norway example, GDP per capita is indeed high in Norway but taxes etc. are also high in Norway, meaning people in Norway might in fact have less purchasing power that their supposedly poorer neighbors in Sweden or Finland. Let me use a model to... |
Why are there oil reserves? Why is there a huge amount of oil all together as opposed to it all being spread out? | Oil is less dense than rock, which means that the pressure of the Earth pushes it upwards, like how oil floats on water. Sooner or later, the oil encounters rock it can't pass through, and gets stuck. More and more oil gets stuck behind this rock, forming an oil reserve. |
Why is my bathroom always cooler than the rest of my house? | Your toilet is a heatsink. The water in the bowl and the water in the tank enter the room at a temperature lower than the rest of your house . The air in the bathroom will slowly heat up that water, but every time you flush you bring new cold water into the room and remove heated water from it. |
Why do humans get pimples? | Pimples are simply infected clogged pores in the skin. Other mammals get them, but humans have rather strange skin for mammals and so we get strange pimples. Asking 'why' we evolved a thing is always conjecture, but in this case it seems to be like asking 'why' we evolved to have absessed teeth, or ingrown toe-nails. I... |
How does Google Maps suggest the same quicker route to everyone? | It's self-limiting. That route, if congested to a high degree, will no longer be the fastest route, right? At that point, Google will stop sending people along that route and choose another. |
How do I "see" my thoughts? | Mental images come from the brain's visuospatial sketchpad, which is itself a part of working memory. You're not literally seeing the imagined image, but you are recalling it from memory. Here's some interesting reading: _URL_1_ _URL_2_ _URL_0_ The funny thing is, it doesn't use the visual centers of the brain, so .the... |
How do vibrations dissipate? If I were to crash cymbals in space would they ever stop vibrating? | Some of the energy from the change in shape turns into heat. In metals, this tendsto not be much. In rubbers and plastics it is a lot more. Vibrations are things moving back and forth. Imagine a ball on a spring. You push it and the spring moves, then it comes back to where you pushed it. It keeps going back and forth.... |
Why does animal breath not stink as bad as humans if we don't brush our teeth? | A modern diet, with cooked food, high protein/carb content, and much less roughage than we'd get eating raw food, isn't the diet that our teeth/mouth/saliva developed to cope with. The flip side of radically better nutrition via cooking is that it's hard on our teeth. Other animals, on the other hand, are eating exactl... |
Why is it that when your breath is bad, or you've been drinking alcohol, it's very hard to smell yourself but other people can smell it easily? | You're constantly exposed to your own bad breath - you essentially "smell" ot every time you breathe out - and so you become desensitized to it quite quickly. Other people aren't, though, and so they notice it when you don't. |
The AT & T Next program. How badly am I getting screwed compared to the 2 year contract plans? | Old plans that had a minute limit and didn't automatically include text or data were technically priced higher to make up for the fact that a cell phone company was going to give you a discount on a phone. The plan's price was technically higher than it had to be. So even thought it seemed you were getting a big discou... |
Why does something with a lot of sugar in it (cake, cookie, candy etc...) taste sweeter than just pure sugar? | The answer is salt. Adding a little salt makes the glucose receptors more sensitive. When I make apple sauce, I add a little salt which means I don't have to add any sugar to make it sweeter. _URL_0_ |
If I lift appropriately heavy weights I REALLY can't do any more than say 10. How come if I then wait just 30 seconds I can squeeze out a few more? | Your body needs to breathe if you will. Your muscles and every other cell in your body needs oxygen . Normally your cells use aerobic respiration to power your muscles for the reps but if you are really working out you'll use up your oxygen supply faster than you can get it in by breathing . When this happens your musc... |
Why does a re-lit cigar taste much more foul than a fresh one? | The chemical structure of tobacco is changed when it's heated up, and it doesn't revert to its original state when it cools down again. It's this effect that changes the flavour.Sorry I can't explain in any more detail than that. |
What Herd immunity is and how it works. | There are 100 animals in a pen. 99 of them have been immunized. 1 hasn't. The likelihood of the 1 getting sick is practically 0% because there are no other animals that could bring the disease into the pen. |
Federal ban on Medical Marijuana lifted, what this means for Federal employees | No. Employers can still prohibit drug use . That has nothing to do with the recently-passed Federal spending bill, which only prevents the Department of Justice from spending money to stop medical marijuana in the current 32 states that currently allow it according to their state laws. The states were specifically list... |
Why chapstick is also sunscreen | Simply put, it is in order to prevent sunburn on your lips. This actually happens to people and can worsen chapped lips or be the reason you are using chapstick in the first place. |
Why is there nothing Saudi Arabia can do to destabilise Iran but Iran have every possible means to destabilise Saudi Arabia and other Gulf countries, namely Bahrain? | Have you seen the price of oil? Saudi Arabia is deliberately getting other OPEC members to keep up production as a way to accomplish several political goals. It helps ruin the US shale oil market, but it also hurts Iran and Russia . Because of the low oil price, the economic gains from Iran opening up to the world aren... |
how do Americans do math | We don't actually use those kinds of numbers in the US! You won't be doing those sorts of calculations unless you're either a student or an engineer of some sort. As a student, you're given problems with numbers that aren't this crazy -- it won't be 38 feet and 3 7/8 inches unless they're making life tough on you on pu... |
why is it not possible to mentally "think yourself" into having feelings similar to the effects of MDMA? | Meditation can work. I will focus on an object until I can feel my pulse through my finger tips and my heart beat is kinda rocking me back and forth. Then I go for a walk. Moving and looking at things is pretty fantastic thenIf you could control your emotions to that degree you would have no reason to reproduce or eat.... |
Why do antibiotics make you sunburn more easily? | Antibiotics are poisonous to bacteria. When some drugs break down in sunlight, they become harmful to human cells. It's not enough to poison your whole body, but you'll get a [chemical sunburn]. Different substances cause an allergic rash in combination with sunlight. That's why you're supposed to cover up with clothes... |
The science of soap! | Oil and water don't mix. But! Soap sticks to both, so when you run water over your hands, the dirt and grease goes with the water instead of stubbornly hanging out on your filthy skin. ^_^ |
What causes a company's stocks to go up or down every day? How is it related to a stock exchange? | A company’s stock price is merely its perceived value to people and how much people think it’s worth. The price of a stock is not definitively based upon whether a company is doing well or poorly - but that is generally the case as to what drives people’s notions on the value. Example 1: company has booming sales and w... |
Why would they have bromonated vegetable oils (BVO) in soft drinks? | It keeps the citrus flavor oils from separating from the sugar water and floating to the top. Bromine is chosen for its weight and its ability to combine with other chemicals. |
How do hard drives save data? | the hard drive is composed of a metal disk that can rotate, and a "head" that can move over the surface of the metal disk. The hard drive "writes" data by using an electromagnet to magentize or de-magnetize spots on the surface of the metal disk. Later, to "read" the data, it can move the head over these same spots, an... |
How can I have a crippling migraine that last for hours but a little bit of sleep instantly makes it go away? | You need to be seen by a physician Rule out aneurysm, or something else potentially very serious. Not kidding one little bit. Do it immediately. I'm a PT who works under a direct access environment which means I can see patients without a referral, and if you were my patient, I wouldn't touch you with a 10 foot pole un... |
what are chickenpox and why does everyone get it and only once? | It's a virus, and typically with viruses, you only get it once. Then your body has made antibodies for it so it can fight off the virus if you're exposed again. However, your body doesn't completely cure you of the virus. The virus stays dormant in your nerve tissues. Then, years later, it can resurface, but instead of... |
Why were cars designed to only run on gas | It's inexpensive , gasoline has a lot of stored energy per unit of weight, and we have an infrastructure in place to get gasoline out to nearly every city. If Tesla superchargers existed on every street corner, Tesla electrics would be more dominant. If there wasn't such an environmental detriment to using gasoline, th... |
If we know exactly how cancer begins and we know the process by which it spreads, why are we no closer to eliminating it? | Let's take a step back, what is cancer? Cancer is when a cell rapidly and uncontrollably replicates, thus forming tumors. Then what causes this rapid division? A screw up somewhere within the DNA when transcription/translation happens. Basically, cancer is a genetic fuck up that causes rapid division, knowing this does... |
The Kennedy Assassination "Magic Bullet" theory | People believe that for Oswald to have shot both President Kennedy and Texas Governor John Connally with the same bullet it would require some outside force like magic. They look to the fact that Kennedy was sitting directly behind Connally. They say that at the angle Oswald shot at it would be impossible for the bulle... |
The rise and (particularly) the fall of Lance Armstrong. | Allegations began after he made such a miraculous comeback after getting cancer. Blood/Urine tests taken more than a decade ago tested positive for drugs that they didn't know existed back then. There is no way to conclusively prove that he was taking those drugs, there could have been many reasons why those blood test... |
Why does bread cook with a dark, thin crust? Shouldn't it cook and get gradually lighter closer to the center? | The surfaces of most breads are glazed with something like egg wash , butter/oil, or some other means to enhance the browning of the crust. Even without that however, the dough-ball is not a homogeneous and the inside is much wetter than the skin, which is quite dry. The hot dry air in the oven dries it out even more, ... |
Why is it easier to get sick in cold weather rather than warm weather? | Two reasons that I know of, cold weather holds less moisture so nasal membranes dry out, making them more susceptible to the cold virus, and people tend to stay indoors cooped up together. |
Was everyone just smelly before the invention of modern cleaning products? | Pretty much. People who lived in the woods would bathe in lakes or rivers and that can get you pretty clean. They would use plants like the luffah to rub on their skin as a scrub. Rich people were able to have bathes. However, besides that there were a lot of people who had a hard time getting the amount of clean water... |
If it's extremely uncommon for cows to give birth to more than one calf, why do their udders have 4 nipples? | Because they evolved from other creatures that had larger litters, and there was no evolutionary advantage to losing some teats. |
Lobbyists. What do they actually do to "lobby"? | The idea of lobbyist is to inform politicians of special interests. Lets say you have a park across the street that the city plans to sell off to build a convenience store. You may lobby the politicians to not do that because it would negatively impact you because your kids lose a place to play. Prior to your lobbying,... |
How is the average number of sex partners different for men and women | There are a bunch of factors that you're not considering. First, people lie about how many sex partners they've had. Different genders probably lie at different rates, given the prevailing cultural values around sex. Second, homosexual and bisexual people are generally included in these studies. The rate of homosexual ... |
What does audio mastering exactly do to make music sound better on every sound system? | Audio is first recorded, processed and mixed. Once the audio mixer has done her/his job; they will give the mixed audio files to the mastering engineer. Well mastered audio should sound good on many different systems. So the one doing the mastering will listen on many different systems to see how it sounds. Most humans... |
Why haven't eggs being marketed by Brands as they have done with milk? | Eggs are a commodity - generally people dont look for labels, they buy whatever is cheapest becuase consumers really dont think there is a difference between one egg brand or another eggs are eggs. Egg farmers know this, so instead of trying to get consumers to buy one brand over another, they all pay money into an Egg... |
how do cemeteries work? When you buy a plot can you do whatever you want with it? if the cemetery falls into disrepair does it breach a contract? | You only have the rights granted to you by whatever agreement you sign with the cemetery. Generally, there are two rights: the right of the deceased to be buried there, and the right of the family to visit and prevent its desecration. Cemeteries are required to maintain the plots and could probably suffer criminal and ... |
Is the orange (fruit) named after the orange (color) or is the color named after the fruit? | Actually the name of tree which bears the fruit came first. Then came the fruit and finally the color. |
What is Kim Jong-Un's plan? Why is he flexing for a war he won't win? | I'm going to repost my answer to a similar question: "It's complicated. North Korea is itself quite weak, but they have the backing of China who view it as a useful buffer zone between it and Western allies, e.g. South Korea. North Korea, however, isn't essential for China so they need to make themselves seem threateni... |
Why is our heart on the left side of our chest, instead of in the center? | Well, it is in the middle - kind of - but leans a bit to the left. You could also ask why the stomach is on the left, or why the liver is on the right. Organs that we only have one of cannot all fit exactly in the middle lest we have a very long torso. As far as I know there is no particular biological reason for this.... |
Why do people say 'Cheese' when taking a photo? | Saying the "EE" noise looks like smiling. Why it's specifically cheese and not like breeze or please or any other EE word I do not knowIn the old days when a "pursed" or "pouty" mouth was deemed the correct facial expression the photographer would have people say "prune" |
why 1T hdd for a desktop PC its so big? A same capacity for laptops its a lot smaller. :\ | Nothing's stopping you from putting a laptop HDD in a desktop. *Very* generally speaking, smaller electronics tend to be more expensive. So if you *can* make a slightly cheaper version because you have the space for them, you may as well. But, again, harddrives have standard interfaces, and you can put any standard dri... |
github ? Why are people attacking it. | Github is a website that allows developers to put up copies of their projects. It's designed for collaboration- anyone can grab the source code of a project hosted on Github and start working on it themselves. Among the many other projects on Github and a large number of projects from top tech companies like [Microsoft... |
Food gives us energy but why does everyone get tired after eating a large meal? | It is all to do with sympathetic and parasympathetic. Drinking coffee, fasting or sudden fear put your body in a state of fight or flight where your adrenal pumps out adrenaline chemical. That switchs off healing, relaxing etc. In another words, your body is burning fat. On the other hand, eating a complete meal of car... |
If a basketball player could dunk by jumping from the 3 point line, would the basket count as 2 or 3 points? | 3 points, per the NBA rule book. > A successful field goal attempt from the area outside the three-point field goal line shall count three points. The shooter must have at least one foot on the floor outside the three-point field goal line prior to the attempt. The shooter may not be touching the floor on or inside the... |
Why is a fly swatter so much more effective than anything else? | The holes allow the air to flow through them. If it was flat, the air that builds up on the face would push the fly out of the way. At least that's how I understand it. |
Why does 30C air with 100% relative humidity feel hot and sticky while 30C water in a swimming pool feels cool and not sticky? | Because they're two totally different environments - one is 100% gas , one is 100% liquid . And because of that, they have different heat transfer coefficient, so your heat exchange rate with them is dramatically different. Also, your sweat will be carried out with ease when in liquid, but has a hard time to evaporate ... |
What would we see if we stand at the edge of the universe and face outside? | There is no edge to the Universe. If you stood at the edge of the *observable* universe, you would see essentially the same thing you see here; a Hubble volume, with the Milky Way obscured behind the CMB, and a bunch of isotropic, homogeneous galaxies. |
Stock options with a private startup company that subsists completely off of prospect investors? | A private company can have stock. The difference is that with a public company, you can just buy their stock at a stock exchange. With a private company, you'd have to acquire stock directly from a current stockholder. The price is determined in exactly the same way anything else is: whatever the seller and buyer agree... |
Why does a 4 oz (112 g) chicken breast have only 110 calories when protein is 4 cal/g and fat is 9 cal/g? | A chicken breast isn't 100% protein. Usually, meat has around 20% protein content. Like human tissue, chicken meat also consists of a large amount of water, and water doesn't contain any calories. |
Why are fidget spinners popular? | They help kids concentrate who have ADD/ADHD issues. I work at a middle school and lot of kids have them, and have seen improvement in their school work, surprisingly. However, its become a toy. The kid in the class who has one will attract the attention of everyone around them, making them a nuisance sometimes in the ... |
How a moderately sized island in the North Atlantic (Britain) took over a country a dozen times larger and more populated than itself on the opposite side of the world (India). | The English arrived as traders in India in 1600. At the time most of the Indian sub-continent was united politically under the Moghul dynasty. The Moghul Empire crumbled about a century later, as various Indian powers attempted to wrest their freedom from the Moghuls, who were considered an alien power. The British exp... |
Why does human feces look so different compared to other animals? | Probably differences in biology. For example, rodents tend to poop in pellets while birds squirt liquid poop whenever. Some animals even eat poop . Bunnies even have to eat their own poop to get their proper nutrients. |
Why cant iOS developers just write a app to jailbreak any ios device and just have individuals sign it themselves in xcode? | The difficulty in jailbreaking is not to get an application to run, it is in finding a way to trick the operating system into allowing the application to permanently modify the operating system itself. In other words, the range of functions that an application can perform is limited. It's in a "jail" of sorts which gre... |
Why cockroaches can survive nuclear Holocaust. | Radiation damages cells when they divide. Humans have cells that are constantly dividing, so radiation is dangerous to them at pretty much any point. Roaches don't have as much cell division going on as humans. Instead, their cells tend to divide in spurts when they are molting . Since only a few roaches in any given g... |
The domestication of dogs. | Dogs and wolves are scavengers, they would follow human groups around because there was free food to be found from hunter's kills and other cast off food scaps. Some might be killed or driven off by humans, but over time the wolves/dogs who had a better temperament and could provide mutual assistance to the people migh... |
Why don't rich tech companies like Apple invest HUGE amounts of cash into battery research? | They do allocate massive amounts of money into the development of battery technology. They develop each upgrade of battery that their various devices use.Battery technology is one of the largest and hottest areas of research in electronics. Companies like apple, Samsung, Google, Nokia, and anyone else who makes mobile ... |
How can America Subpoena people from other nations and what will happen if they don't comply? | The USA can't enforce subpoenas against citizens of other countries without cooperation of the legal system of that country. Often that can happen however. |
Why has the video quality of Skype and similar applications remained relatively poor even though residential internet speeds have increased exponentially in the last 15 years? | Short answer: Skype uses real-time unbuffered 2-way video without a content delivery network. When your computer receives anything from the internet it is divided into lots of pieces. At any point these pieces can be lost or delayed and your computer has to request them again. Even on a good day many pieces of data wil... |
How does my computer know how much time is remaining for a program to be installed? | It's an estimate based on how much data there is left to transfer and how fast it is currently getting done. |
Why does the quality of a subreddit degrade when it gets bigger? | I guess cause More people = more posts, More posts = less mods per post. From there, not everything can be filtered the way it was before and therefore the quality of posts decrease. |
Why do some spicy foods burn only certain areas of the mouth or throat and not others? | The source of the spicy feeling is a chemical called capsaicin, that activates receptors on the burn-sensitive nerve fibers. I doubt that the form of the spice is different between foods. The difference is more likely in how you eat it. Hot wings get the sauce all over your lips before it gets to your throat. Lips are ... |
Why are sewers underground and power lines above ground? | Well a lot of power lines are underground now, but long transmission lines are up high for several reasons: - The transfer of electrical energy has a byproduct of generated heat. Placing the lines with plenty of moving air helps to cool the transmission element and preserve their integrity - It would be way more expens... |
The Keynesian School Of Economics | Keynesian Economics is all about preventing booms and busts from happening during the regular business cycle.

Orbit. What stops celestial bodies from being pulled into each other. What stops the earth from being pulled into the sun? | The answer is speed. Orbit is actually "falling" towards an object, but "missing" the surface because you're already way past the curvature of the surface. A great example is [Newton_Cannon] where in the ball "falls" towards Earth but has such high speed forward, it "falls forever". |
how did hillary have like 350 delegates before any states voted? | Those are the superdelegates, also called unpledged delegates, they are a way for the party to have influence on the nominee. They were introduced in the reforms after the 1968 convention, as the tradeoff for primary elections having substantially more weight in the nomination decision . They are VIPs like national ele... |
Why do humans consider faces an important factor for attraction? | Faces are where we express most of our emotions, and our brains are very good at recognising people by their face and how they feel by their facial expressions . Because we spend a lot of time looking at faces and are able notice many minuscule facial details, it is one of the areas we are most sensitive to detecting a... |
How a scene in Maya can take several hours to render yet a modern game can load an entire world in seconds | Video game graphics are optimized to render fast, use shortcuts, and are typically lower resolution than what Maya producesMaya works using ray tracing to render a scene, so for each pixel your computer traces light paths that will be affected by the properties of the material you are using like reflection and refracti... |
Why doesn't everyone just send mail without postage and put the intended destination as the return address? | You're not the first person to think of that. If you put the return address in Oregon and send it from California, they know and can charge you with fraud. Not really worth saving 40 cents. |
How is Tesla able to improve the efficiency or performance of their cars with over-the-air updates? | It's the future, man. Nowadays, computers control every aspect of cars from running the engine to turning on the interior lights when you open the door. Electric motors are controlled by changing the voltage and current running to them. More voltage means more torque and more current means faster speed . Engineers use ... |
How does unlimited online storage work? Where are my files actually stored? | Your files are stored on a hard drive in a computer in a data center. They're also probably backed up to a second drive or to tape. Storage is cheap: in bulk a company might pay only $30 for a 3TB hard drive today, so if they charge $10/year and the average customer uses less than 1TB, then they 've paid for the cost o... |
Kierkegaard concept of demonic despair | I am aware that my parents created me, but I feel they have done a poor job. I feel like I could be a better master of myself than they if I could exist independently of them, but I know this is impossible. Thus, I am angry with them and I despair. The solution to my despair is to reconcile with my parents, but I refus... |
What is the difference between am automatic and a semi-automatic weapon. | Automatic guns are what people commonly think of as "machine guns". You hold down the trigger and it fires round after round. Semi-automatic guns are most guns out there. Each trigger press fires only one round, and loads up the next one, so you can just press the trigger over and over to shoot over and over. Other gun... |
Can the United States Military see their own stealth planes on radar? | Not going to happen, since it's not GTA and jets take at *least* a couple of minutes to start up. And that is if the pilot knows very well what he's doing. During flights where stealth is not required F-22 can be seen flying with decidedly non-stealthy external tanks and with special reflectors in place designed to mak... |
