lets see 1) Megabit vs Megabyte, 1 megabyte is 8 megabit, so if you have 10Mbps from your telco, you probobly have 1.25MBps 2) Protocol overhead, the data dosnt go un a raw format, its usualy packaged in a protocol called TCP/IP which requires envalopes called "packets" with their own structure and inner detail, this u... |
This line of thinking is exactly what led to the Big Bang theory of cosmic evolution. Scientists initially believed the Universe to be infinite and eternal, but if it was so then surely every line of sight in the sky should end on a star, and the night sky should be completely bright. Therefore, the Universe must eithe... |
Part of the problem with you question is that "looking" is something that is not independent of size. Visible light has a wavelength from 390 to 700 nm (3.9 to 4 x 10^−7 m) while atoms have a radius of 30 to 300 pm (3 to 30 x10^-11 m). So seeing is not really applicable here visible light does not work at this scale. A... |
Because in the United States the Industrial Revolution started to make monthly accounting more common. The year was too large a time to bother with (yearly books were kept, everything was assumed part of the same year) and days were too short a period of time to be the primary sorting number. Months then were made to c... |
If a plant blooms and the flower is damaged by snow or ice, the result would be that the plant will not produce fruit that year. The plant will not die, however it needs its flowers to develop in order to make fruit and seed. |
General consensus that I have read is the Maldives, Tuvalu, Kiribati and Vanuatu will be the first countries to be submerged. New Zealand already had a man from Kiribati (low lying Pacific island) and a family from Tuvalu apply for refugee status due to climate change. IIRC, the claim was not allowed. People in parts o... |
> How does it work Getting sexually aroused requires a specific chemical reaction in your body. When you're chemically castrated, you take chemicals that stop that reaction from happening. > and is it permanent Generally no, but those same chemicals can have undesirable side effects that may or may not be permanent. (L... |
I can walk around while brushing, I just don't use a ton of toothpaste and keep my lips closed. Perhaps I don't salivate so much. Not that I do this regularly, I prefer to keep it at the sink and get it done because multitasking while brushing is counterproductive. You've only got one hand, can't talk, and a mouthful o... |
Car sickness is a form of motion sickness. Other common motion sicknesses are seasickness, airsickness, and the sickness you feel from watching shaky cam movies like Cloverfield. All of them have the same root cause - the motion you sense in your body doesn't match what is reported by your eyes. For example, I get moti... |
Appalachia relied on selling things that they found or could grow that people elsewhere wanted. Namely coal, lumber and tobacco. All three of these things are no longer wanted in very large quantities. The people that lived there have not got the skill-set to do alternative work, therefore industry thinks if they set u... |
If discipline breaks down in any army, it severely reduces the capability of the entire unit to operate. Put simply, this means that lots and lots of people could die. So, lets consider civilian life someone refuses to do what his boss says. Well, generally, a sale or two could be lost - or a project delayed, or maybe ... |
Trees make other trees by dropping seed. Not many seed live to grow up to be big new trees, so the tree wants to give the seed it drops the best chance possible of living. So firstly the tree needs to get the seed away from other seeds as much as practical as you've never seen trees grow right next to each other, have ... |
Energy cannot be created or destroyed locally and within our universe. The big bang was not an event within our universe - it was the event that started the universe. The usual conservation laws do not apply. Quantifying the "total energy in the universe" is problematic at best. We don't really know how to. One of the ... |
Part of the magic of making ice cream is that little tiny air bubbles get whipped into it, and tiny globules of fat are mixed throughout the ice crystals. When it melts and re-freezes, all those bubbles get released and the fats can separate a bit, so you're left with something closer to greasy ice. |
Weather changes are often due to changes in air pressure. Have you ever heard a meteorologist talk about a low pressure system moving through or anything? That's what they are talking about. One of the factors that makes wind is air moving from areas of high pressure to areas of low pressure. If they are very close tog... |
Well I don't personally think that a single violin sounds harsh I know that some people upon hearing A violin played badly I will think it harsh. When multiple instruments played together there is an affect called chorusing in which the individual instruments are just slightly out of tune with respect to each other . T... |
In some ways, it's fine and in some ways it's not. Generally it is considered unhealthy to replace *all* meals this way, but there are some benefits to replacing some meals this way. Vitamins in powdered form have low bioavailability, meaning your body doesn't absorb them as easily. Vegetables and fruits are better at ... |
There's a phenomenon called 'osmosis' which plays its role here. When two different liquids with different concentrations are separated by a semipermeable membrane (the one that allows one-way flow only), the liquids would flow in such a way that they attain a state of equilibrium, i.e. now the concentration of both th... |
Well, it's not. The economy as a whole does better when oil is low and does worse when oil is high. However, the oil industry itself does terrible when oil is low and well when oil is high. So local areas that have a lot of oil jobs (the gulf coast, fracking towns in the Great Plains, etc.) tend to swing in the opposit... |
They check for an @ symbol and a domain extension such as .com or .edu It doesn't normally do any test to check if the address is reachable etc |
When the Earth was much hotter, and everything was much more liquid, things could flow a lot easier. Just like putting oil in water, these molten metals and minerals will tend to separate out due to their different densities. They then cool and solidify, and billions of years later humans find them in clusters. Element... |
A lot of anthropologists and evolutionary psychologists are coming to blame agriculture for this. Agriculture and fixed city-states are a fairly new invention, about 10,000 years ago -- an evolutionary eye-blink. Prior to this, humanity operated in a hunter-gatherer clan-based society, where scarcity of resources deman... |
They plan the landing sites well in advanced. It is determined by terrain (will it be a safe landing), different features (what looks interesting to study), and by past landings (they want to spread out so they can study as much ground as possible) |
Commercial movie cameras were literally hand-cranked affairs, and number of frames exposed per second depended on how steadily the camera operator could crank. Also, film was less sensitive to light than later on, so most cameras exposed fewer frames. Home cameras, when they came out, generally used spring mechanisms w... |
Your IQ tells you how well you did on an IQ test, which means next to nothing. It is SUPPOSED to measure how smart you are relative to the rest of the population, but there are so many flaws with IQ tests that most people with any sort of understanding of the situation doesn't take them seriously. I can go into some of... |
Fish spines have evolved to swimming and underwater locomotion, and that made their spines more flexible vertically = vertical fins. Mammals evolved to move on on land and to run, so their spines evolved to be more flexible horizontally. Then marine mammals went back underwater and developed fins, and as their spines w... |
the force of your lungs sucking in air to breathe is less than the force pulling the air past your head. it's similar to running against the wind on a really windy day. if you could suck in air stronger than the wind is blowing it around your mouth, you'd be able to breathe. |
To make this a lil easier to understand, let's use another more familar form of electromagnetic energy: visible light. Same basic principles apply! Using your cell phone and its towers to communicate via microwaves is like getting a message from someone who's flashing a light on a hilltop far away. His light doesn't ha... |
This actually dates back to prehistoric times, when people didn't approve of something or didn't like it they would mimic the sound of a cow--which eventually through time turned into what we know as "boo" |
There are many tradeoffs for eyes. Predators generally have forward-facing eyes to focus on prey while prey tend to have eyes on the side of their heads to increase their field of view at the cost of clarity. Birds of prey often have better eyesight because the crystalline lens, the focusing lens inside of your eye tha... |
Because their brains are not developed in the parts that regulate dangerous behavior. Those parts do not fully mature until a person is in their early to mid twenties. That is why phobias tend to develop in the mid to late twenties. Suddenly the brain realizes all the things that are dangerous and could killit that it ... |
There's a number of potential reasons: * What was popular to you/even in your city might not be popular on a national/international scale so they decide to move away from that product and push their attention to a new product * The company wants to consolidate the number of products they offer, the one that get discont... |
The world is certainly overpopulated for the resources we consume. If the average person were to significantly reduce their footprint, then the globe could handle the current population and much more (potentially). That being said, if we got close to immortality i think you would find, in general, lower birth rates. Ma... |
They absolutely do forget how to speak. It starts with people forgetting certain words, and then they'll confuse their grammar and in late stages, many patients can only communicate with pictures. In general with dementia, declarative memory (knowing 'what') leaves you before procedural memory (knowing 'how') does. Whi... |
Smoke detectors work by having a radioactive substance and a radiation detector inside. The detector keeps getting the emissions from the substance, and this keeps a circuit open. Whenever enough particles that can block the radiation get between the emitter and the sensor, the circuit closes and the alarm goes off. Fi... |
Light comes in a variety of colors, and when you have all of these wavelengths together we see it as "white" light. The name "white noise" is a reference to "white light" where a bunch of different sounds all cancel out to the point where no single sound is divisible from the whole. |
I imagine with coffee, someone probably tried brewing it or cooking with it and noticed that it gave them a buzz from the caffeine. Regardless of how it tasted, they appreciated the buzz and maybe got hooked. Further, I would think that many other acquired tastes were eaten out of convenience or perhaps even a supersti... |
The objects that Hubble observed at those distances are super-bright galaxies, hundreds of thousands of light-years (*hundreds of quintillions of miles*) in size. The planets of Trappist are, well, planets. They're probably a few tens of thousands of miles in diameter and emit no light of their own. Compare using a bac... |
Carbonation is held in soda by the pressure, which forces gas to dissolve into the liquid. You'll notice that once you open the bottle of soda, you hear a hiss. This is pressurized gas escaping from the bottle. When you drink some soda and then re-seal the cap, the pressure inside the bottle is not enough to keep the c... |
When you stitch a wound shut, most of the cells are still alive. The stitching just holds them in place while the cells heal the wound. Without stitches, the wound may still heal, but it would take longer and be more prone to infection as well as leave a much larger scar. Also, the stitching thread itself is not "accep... |
From personal experience with root beer brewing at home: They don't always. Root beer is fundamentally similar to other soft drinks when store bought in terms of the base (carbonated water), the flavor (emulsified oils) and the sweetener (unfortunately usually high fructose corn syrup). However, many brands add somethi... |
Whether or not you call a small feline animal "a cat" or "el gato" doesn't change what you're talking about, it only makes some things more or less complicated. The same is true when talking about number bases. It's just changing vocabulary or speaking in a different dialect of the same language. Basic math would still... |
My guess is that it has something to do with the fact that you're in a better place to judge the clearance of the vehicles you'll be passing in the other direction Remember that the old name for a car is a "horseless carriage." Horse drawn carriages could get severely damaged if the horses or wheels bumped against one ... |
It is the anti-matter counterpart to an electron. It is almost exactly the same as an electron, except it has a positive charge. When it reacts with an electron, they are both annihilated and converted into pure energy. Positron are created by some forms of nuclear decay and in particle accelerators by smashing things ... |
You'll feel bloated and full if you drink it all at once. If you're exercising or playing sports it's very important to drink smaller amounts every now and then so you won't feel full. If you're trying to get hydrated drink pedialite ( or store brand equivalent ) it has the proper isotonic properties to be most efficie... |
Storms that create tornadoes form when warm, wet air from the Gulf meets hot dry air from the desert, and cold air from up north. Wet air warms up in the sun and tries to rise up because it's getting less dense (like the air in a hot air balloon), but the hot, dry air from the desert is already up there, holding the wa... |
The Darien Gap is an ecologically sensitive war zone. Building a road there would be dangerous and bad for the planet. Consider that the purpose of the road would be to connect Panama to Colombia, yet both the Pacific and the Caribbean offer means for shipping and ferry service without the hazards of a new road. Cost, ... |
Egg is a viscous fluid, and when it moves, anything trapped inside it moves also. Your finger "pushes" the egg away from itself when you go to fish out the eggshell - however, the egg pushes the eggshell away from your finger because it is viscous. Think of how jello would behave if you pushed on it, egg is like a more... |
Rainbows function by bending light. Specifically, [light enters a water droplet and bounces off the far side at a 42° angle]( URL_0 ). All the light originated from a certain point (the Sun). So there are a limited number of paths that light can travel from the sun, to bounce off a water droplet at a 42° angle, to hit ... |
There are three main categories of receptors in the skin at play here. We have warmth receptors, cold receptors, and nociceptors (pain receptors). Warmth receptors begin firing (meaning sending signals to your brain) around 30 degrees Celsius to about 45 degrees Celsius, at which tissue is destroyed. Cold receptors hav... |
It's a reference from the movie The Matrix, where the protagonist is offered a choice: to take a red pill and remain aware that they are all in a simulated world, or to take a blue pill and lose his awareness of the fact that the world he's been living in all his life is just a simulation. Since then, "red pill" has be... |
Alcohol inhibits the pituitary gland from producing anti-diuretic hormone (ADH). ADH is what tells your kidneys "When you're done processing that waste, re-absorb most of the water". So water goes right through your kidneys to your bladder and you have to pee a lot. By the by, a hangover makes you feel like crap becaus... |
Everyone here talking about radar seems to be overlooking the fact that ATC radar **cannot** determine the size of the aircraft, and literally thousands of aircraft in the US operate without Mode C transponders. If you are operating in airspace that has no Mode C transponder requirement (Class E and G. Technically clas... |
Because you (by you, I mean the consumer) don't pay a redemption value on other plastics you buy, even if it's made of the exact same plastic. If your soda bottle was made at the same factory as the ones who makes plastic containers for something else (say like the container for Orange Juice or Apple Juice) and you did... |
There are a few reasons for this. First is the shear size of the US Economy. The US represents 25% of the entire would economy. There is no other country that is even close. The US economy is the size of the 2nd, 3rd, and 4th largest economies put together (China, Japan, and Germany). The other big thing is the stabili... |
I answered this [a while back]( URL_0 ). > First of all, falling asleep is a very smooth transition. You don't go from an awake state to a deep sleeping state within seconds but rather go from awake over pre-sleep, light sleep, slow wave sleep to REM sleep. > > **Memory formation depends heavily on changes**.

Antidepressants affect many things. Ranging from your inability to get motivated to do something, to your suicidal impulses. The issue is that they do not affect these things all at the same time and it is common for antidepressants to improve your mental status enough that you are able to become motivated earlier than... |
Actually, your premise is not quite correct. There's a difference between a "fatherland" and a "motherland". A "fatherland" is the land that belonged to your (male) ancestors -- your father, grandfathers, great-grandfathers and so on. The Latin for "father" is "pater", which gives us words like "patriot" and "repatriat... |
There are a few reasons. * A lot of the work done for a series is only needed once - hiring crew members (including actors), finding locations, making props. You don't need to do all that for every episode. * You can also shoot multiple episodes at the same time - usually, a movie will have just one or two directors an... |
Calling it a law is a bit of a disservice. It was actually an observation made by Moore. The distinction is important. As for your question, AFAIK it is mostly due to the progress of manufacturing and production of chips, rather than any willingness to prevent progress. It is expected that Moore's law will break down o... |
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... |
The director needs to plan an episode, get rewrites, shoot for 1-2 weeks, then supervise the edit and completion. It's a big job. It's too long for one person to do 13 episodes back to back, so shooting is split into episodes or two episode tranches. |
I believe it's from the constant adjustments your body has to make from being bumped around. You never get the opportunity to sit still like you would on a couch. Stress may also be a factor, in addition to the physiological impacts the others stated. Feeling tired may be as much a mental situation in some cases based ... |
Its important for kids to learn about their body since they're about to experience, or are starting to experience changes in their bodies. It's not as important for Johnny to learn that Katy might like it if he were to choke her a little while he sticks his dick in her butt Seventh graders learn about sex in the sense ... |
The battery WILL last 16 hours in lab conditions i.e. with the product turned on and doing nothing. When you start to use the device, it requires more power to run the tasks you are doing so the battery is being used quicker than if it's sitting idle. |
Your skin is made up of three layers: the epidermis, the dermis and the hypodermis. Only the epidermis replaces itself regularly; damage to the epidermis will not result in scaring. Deeper damage - to the dermis or hypodermis - results in scarring as these layers do not get replaced as often. |
The average process of digestion takes between 8-12 hours. If you eat something toxic, it would be very bad for you to have that sit in your body for that length of time, with all of those toxins being absorbed by your digestive tract. Thankfully, we have developed a "purge" mode where, if the body senses that it has c... |
While I cannot entirely think of why you'd prefer certain movies over others (innate preference is much more complicated), what your brain finds interesting is rather simple. You brain is addicted to stimulus. In fact, it's so addicted that it would rather choose [physical pain over heavy boredom]( URL_0 ). Usually, wh... |
The answer is that there are multiple ones. In fact there are over 200. Of which 99 are strains of the Rhinovirus. Vaccination against one strain doesn't seem to give much immunity to the others. They are also constantly mutating and making more and different strains. |
Head lice is a great example of how infection can spread. It doesn't spontaneously happen. Someone carries it, and passes it on. You and your family are lice free. Your 2 kids go to school, one in daycare, one in kindergarten. The kindergarten and daycare are also lice free. Your kid goes to the museum and plays dress ... |
Microwaves work by exciting water molecules in foods. So if you recall there was a commercial years ago of Velveeta and a popsicle being heated in the microwave. The cheese melts first. The water molecules in ice are locked in place pretty tightly. When heating up food the water heats up more in some spots than others.... |
The inner core is solid because of extreme pressures. The outer core is molten because of the extremely high temperatures. It's not a star although radioactive elements have kept the interior hot. Initially it was hot because of the energy coming from rocks coalescing together. You have those two sources of heat (radio... |
First, understand that you're probably talking about different kinds of batteries. "Regular" batteries are probably alkaline batteries. Your phone has a rechargeable battery and that's probably a lithium-ion one. Those batteries use different chemical reactions, so it's not surprising they react differently to differen... |
Think of your memory as song lyrics. If you hear the starting tune or if someone starts singing part of the song, it's much easier for you to remember the lyrics and sing along. However, if you are asked to sing a song on the spot, it's difficult to do so unless you already memorized it. When you are asked about someth... |
They don't. The womb is filled with an amniotic which does help in practicing breathing, but oxygen is provided and carbon dioxide removed via the placenta mainly. Babies breathe for the first time when they are born, that first gasp and cry, is the first time a baby breathes air. They don't. They get nutrients and oxy... |
It only happens with GSM phones. The frequency GSM phones operate at is picked up by the speakers as a signal. The speaker then outputs the signal. It comes across as staticish because it's speaking cell phone not speaker. You mean this noise? URL_0 It's not just bluetooth speakers, any speaker can potentially do it. I... |
Nobody sneaks into anybody's house to bug the phone. They tap the wires right at the phone company. Also keep in mind that just because you have a wireless mobile phone doesn't mean that your calls don't go through wires at the phone company. They absolutely do. The phone company have a lot of routers that route phone ... |
A siren is a cheap way to make a loud sound. It is built like a fan so it moves air very well but is "unbalanced" so it pumps air very unevenly which creates the very loud sound. In a normal fan you would want a constant stream of air to avoid noises and make it cleaner for your application. However a siren is built to... |
With older OS's you could really risk disk and registry corruption when the computer would lose sudden power, however, with Windows 10, I'm seeing little to no effect. My computer doesn't seem to run chkdsk or anything after losing sudden power, and even my Office365 excel and word applications seem to successfully pre... |
Its not a fume, its smoke, and its not easy!!! You have to train your body to take it, because people are to stupid to listen to their lungs and throats. Eventually your body realizes your going to be stupid anyway so no bother continuing to tell you how stupid your being by sending the pain and discomfort signals to y... |
You're hearing your own heartbeat. ~~It's the same thing that causes the whooshing sound when you listen to a seashell.~~ |
Locusts are just a name for grasshoppers who are in a swarming phase. They are still grasshoppers. It happens due to overcrowding. Certain external pressures can result in a population-explosion, and when grasshoppers bump into each other they get a rush of serotonin. This causes them to change color, eat much more tha... |
Your torso is where your body heat is generated and most concentrated. It's where your vital organs are and they need the most protection so you don't freeze to death. |
An "electromagnet" is the term for a device specifically designed to use electricity to create a magnetic field around the device. All wires with currents produce magnetic fields, yes, but mostly they're used to just carry current. In electromagnets they are not wrapped around a magnet, they are wrapped around an iron ... |
I can think of one example.. a non prescription pain killer I use is 15mg of codeine and 500mg paracetamol.. there is a prescription version that is 30mg codeine and 500mg paracetamol.. both versions have a daily maximum of 8 tablets (I think).. from what I understand, the paracetamol is damaging to your liver at high ... |
It's not hard to lose weight really. It's just not fun. You gain weight by eating more calories than you use in a day and everybody loves eating. Especially since high calorie foods tend to be especially tasty. People don't like burning more calories than they take in because it basically means effort, hunger or both. ... |
That black band surrounding the windshield is called the Frit. It provides a textured surface for the windshield to be glued into place, while the black band on the outside protects the adhesive from UV radiation. The black dots are mostly cosmetic, easing the transition from a solid black band to the completely transp... |
Your internet is only as fast as the weakest link between you and a server. Youtube (and Netflix too, I'm sure) has a lot of load-balancing and caching servers that are very close to, or in an ISP's backbone network, which means the route from you to a lot of youtube content is very short and unlikely to pass through a... |
What is happening when you can see the exhaust is that warm water vapor is cooling and collecting into small droplets that are suspended in the air around them. When the exhaust system is cool the water starts condensing before it leaves the pipes. Once everyting is warmed up though the exhaust stays hot enough that by... |
That's only one rotation per day, or roughly 0.25º per minute. Long-exposure photography of the night sky shows exactly the effect you would think, but on the timescale of less than a second, it's fine. That works out to only a degree every 4 minutes. But you do make a fair point and a lot of amateur astro photography ... |
It is a very small rate hike. However, banks will certainly pass that hike on to consumers. Interest rates are at unrealistic lows, the chance of them going lower in the next few decades is very, very small. Now i a better time to buy a house that next year. [This graph]( URL_0 ) shows that fed rates are generally betw... |
Closing your eyes while sleeping protects the surface of your eye from foreign bodies and clears bacteria accumulated through the day. Although your cerebral cortex functions while you sleep, the eyes do not take in information while you are asleep. This enables your brain to process the data it has received already. I... |
IMO a cold bet feels amazing... sliding into cool sheets is wonderful. I wouldn't want it to stay cool, but neither would I want my pillow to stay cool all night. Probably depends on the time of year and we're you're located, in the summer when it's hot out, I love cool sheets, but in the winter, I love warm sheets. As... |
It's possible that multiple households have set their wifi signal to the same channels. Wifi occupies channels in the same way that televisions do. The difference is that multiple wifi sources can occupy the same channels and create interference with each other, like how its hard to listen to one person web everyone ar... |
Actually, they start "breathing" in utero. However, the amniotic fluid is much easier on their system. During birth, the babe "holds its breath" through the birth canal but can often still breath via the umbilical cord. Otherwise any birth lasting longer than 3 minutes would be terminal. After birth, they spit up the a... |
Learn how to form good habits and replace the bad ones gradually. Allow yourself to change your routine. Try to accomplish at least one new thing per day. Remember that it takes 21 days to form a new habit. So pick one habit to change and work on it. Don't try to fix everything at once. Objectify the issue and realize ... |
First 4WD vs AWD. 4WD is generally used in Trucks and SUVs and is generally not an "all the time" thing, it is just engaged when it is necessary. What takes place is a mechanical locking of the differentials to ensure that all 4 wheels rotate "as one". what this means is all 4 wheels are rotating the same amount which ... |
For me I get to escape the torture of being in this reality for little while so that's a nice aspect. Also if you get into lucid dreaming it doesn't have to be "just laying there". I don't think everyone likes sleeping. I wish I didn't have to! And most of my dreams are weird and leave me thinking "what the hell..." |
Spicy things tend to be oil soluble so it takes a bit longer to get it off of the surfaces of your mouth than do water-soluble spices. |
If you injected a cancer cell from one person into another person, their immune system would kill it. The trouble with cancer is that it's *your own cells* going out of control, and your immune system basically ignores it as being part of your body. That doesn't apply when it's cancer cells from someone else's body. |
