Why is it that lots of smaller files take longer to copy than a smaller amount of large files?	[ "There is more to copying a file than just copying its content. The file system keeps a book of all of the files on the drive so this book must updated. If the book is indexed, there is an additional computatipn to calculate the new files index. If you have 1000 4kb files all of this has to be done 1000 times. IRL,...	[ "Say you have a hammer and nail. If the hammer head is bigger than the nail, then the force of the hammer is distributed evenly against the head of the nail. The nail will go straight into the wood. Now say you have a hammer and a nail, but the nail head is bigger than the hammer. When you hit the hammer against t...
At what point does a certain species become a different species? Is there a rule?	[ "From _URL_1_ Some biologists may view species as statistical phenomena, as opposed to the traditional idea, with a species seen as a class of organisms. In that case, a species is defined as a separately evolving lineage that forms a single gene pool. Although properties such as DNA-sequences and morphology are u...	[ "New virus strains are constantly appearing. The influenza virus mutates very quickly and every year there are dozens of new strains that could infect you. That's why you have to get a new flu shot every year. When scientists are making each year's flu shot they look at what strains are currently in the wild and ma...
Why are toy stores been driven to extinction? (Eg Toys R US)	[ "Amazon. There is simply no way for them to compete with online shopping. It’s happening to all the brick and mortar stores, but especially ones like toy stores where you don’t really need to see the product before you buy it. Edit: Source: I’m the uncle for several nieces and nephews. I have yet to step into a to...

What happens to generated electricity that isn't used?	[ "a power plant consists of multiple generators. during peak demand, the plant turns on more generators. during low demand, the plant turns off generators. there isn't any electricity that's generated that's not used. the grid is a transport network, it is not a storage device. now that said...installations lik...

Do potted plants actually "aerate" rooms to any significant degree?	[ "It will make essentially no difference. The effect will be, in any event, generally much smaller than the effect you have of depleting the oxygen in the room in the first place. Which, unless you happen to live in a sealed environment for a long time, is very small. And of course the plant also respires, so if the...	[ "Not at all. One of the most interesting demonstrations of this is breathable fish bags that allow gasses to pass but hold water...pretty handy for shipping fishes without suffocating them." ]
What would happen if I went to space with a mason jar filled it with "space" and brought it back to Earth? What would be in the jar?	[ "It would be mostly empty, maybe a few molecules bouncing around in it. Assuming the jar was reasonably structurally sound, it would likely be able withstand the pressure differential between inside and outside just fine. If the lid was completely air tight, the jar would basically just sit there, acting pretty mu...	[ "So you're getting two different sets of answers based on two different readings of your questions. First, conservation of mass is a thing. Re-arranging molecules won't let you get a higher mass. Even fixing gasses probably won't get you there, because you are expending energy in the process of re-arrangement. Seco...
Why do/how can "zero/low calorie sweeteners" have sugar, specifically dextrose, in them, if they are supposed to be sugar substitutes?	[ "Most say no or low sugar because they generalize glucose as sugar and other forms not. Also glucose is harder to metabolize than say sucrose, dextrose, fructose, lactose etc. So technically they aren't wrong but also not right. No sugar substitutes tend to use saccharin instead of a \"-ose\"" ]	[ "Vote spammers will create dummy accounts to upvote or downvote whatever they want.

Where does the color in food go once we consume it?	[ "Remember when you played with play dough as a kid. If you mixed all the colors up you just end up with a big brown lump?" ]	[ "Not evaporate. The process is generally called photodegradation. Basically the sunlight is providing enough energy for chemical reactions to take take place. There are a huge variety of possible chemical reactions. For example, the photon could whack into a water molecule, causing it to break into oxygen and h...
What year did people thousands of years ago think they were in? What year did they think it was in 100 BC? 1000 BC?	[ "> Did they count down the years at the time, like BC They couldn't have. They'd have no idea what to count down to. > did they count up, like AD Usually they did, however when they count up from varied. For example the Mayans (of 2012 fame) had a calendar based on counting the days since 'creation', which happens...	[ "We use base 16 when programming computers. In order for that to work, we need 16 different \"digits\" - so when we run out after 9 we use letters of the alphabet. So if you're counting in base 16, it goes 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, 10. \"10\" in base 16 really means the number 16, the same wa...
If a population's native language lacks a subjunctive mood, how will that populations world view differ from populations who use subjunctive moods liberally?	[ "There is no indication that our verb forms limit our thinking in any way, shape, or form. For example, you seem perfectly capable of talking about what 'could have been' without using the subjunctive mood, which is effectively gone from English, limited to a few infrequent constructions like *I require that your h...	[ "So, we're talking about verbs here. The definition you learn in school is that transitive verbs take a direct object, and intransitive verbs don't. So a transitive verbs describes an action done TO something, and an intransitive verb doesn't. Here's an easy way to check if a verb is transitive or intransitive. I c...
How is half-life of an element being measured when some isotopes have their half-lives greater than the age of our universe?	[ "You don't have to observe 50% of the material decaying to determine a half-life. You can extrapolate from observing the rate of decay." ]	[ "There's no medium. The waves in quantum mechanics are probability waves. One way to put it is like Feynman said it: there's only particles. But if you want to compute what the particles do, you need to work with \"probability amplitudes\" and it's those probability amplitudes that behave as waves. [Relevant lectur...
Was General George McClellan an inept commander, slightly treasonous, or simple too timid in personality?	[ "Generally speaking, McClellan loved his army to the point that he didn't want to use it unless he could win a battle without losing many men. Also, I wouldn't say he was treasonous, so much as he was gullible. During the Peninsula Campaign in 1862, Confederate General MacGruder simply marched one of his regiments ...

Is it possible to get dizzy in 0 gravity?	[ "Yep. Space adaptation sickness is a thing. Reduced gravity aircraft which travel in steep parabolic arcs, designed to help crews acclimate and experience weightlessness, were given a quite fun nickname: 'The Vomit Comet'." ]	[ "You're right to be confused. It is 100% wrong as depicted in the movie, and a lot of people of wondered about why they made such a grave error considering the rest of the movie was somewhat realistic. It is likely that the reason this happens in the movie is that it makes things more dramatic. Artistic license i...
What is the point of using public key cryptography over symmetric cryptography if both are still cracked through reversing the encryption method?	[ "In symmetric cryptography, the same key is used to encrypt and decrypt the message. If Alice wants to send a message to Bob, she first has to send the message to Bob. This presents a problem - if the key is sent in plaintext, an attacker could intercept it and then use it to decrypt the message. If the key is sent...

In a racecar, the type of collision and the position of the passenger is pretty consistent -- the driver is strapped in like an astronaut. It's bee...
If I were to fire a projectile in space, how long would it travel, on average, before it would hit something?	[ "It would almost certainly hit nothing, ever! That's how empty space is! Assuming we are ignoring the occasional stray hydrogen atom, if you project a straight line into space, it will not intersect any large object (planet, star, asteroid etc). The \"filling fraction\" is just too small. You may quite possibly p...	[ "You've discovered [the twin paradox](_URL_0_). The answer is that you can't have the spaceships \"suddenly\" be at rest with each other. Either one or both must undergo acceleration.

It seems to me the usefulness of hot air balloons before aeroplanes and lighter than air travel could have been increased by adding some manner of steering such as sails or propellers, what am I missing?	[ "So the key factor that made aeroplanes practical at the turn of the twentieth century was lightweight internal combustion engines. Since you need this invention for a propeller driven lighter than air craft, these don't exist before aeroplanes because they depend on the same key technology. (After airplanes, Zepp...

Sometimes, when you most need warm food, there is none because th...
Being in orbit. Gravity vs inertia?	[ "Here is how to think about it. Unless you apply a force on an object, it is going to continue in the same direction at the same speed. (This is what inertia means - there is no \"force of inertia.\") Gravity is pulling the object in orbit towards the planet - it is accelerating \"down.\" The acceleration is pointi...	[ "Imagine firing a bullet fast enough that it falls toward Earth at the rate the Earth curves beneath it. Its always accelerating towards the center of the Earth but never gets any closer. This is precisely what the ISS and other satellites are doing." ]
What happens to people who die with no family to pay for the funeral/burial/cremation or no one wants to?	[ "Typically unclaimed bodies are cremated and their ashes are scattered. Some places actually bury the bodies, but that's less common." ]	[ "Well, very sadly... those exposed to hot ash and pyroclastic flow from volcanoes are essentially rapidly/instantly baked (alive), and quickly turned into charcoal and carbon, with their body usually being subsequently broken up into powdered carbon ash particles. -------------------------------- Also, given how ...
How can we say with certainty that no two fingerprints are alike when we haven't verified it with every existing human being, including those from the past?	[ "We can't say it with certainty. There is no basis for the belief that no two fingerprints are alike, and very little evidence that fingerprint identification is reliable in general." ]	[ "Basically, you have to be weaker if you want the kind of fine muscle control we have. Chimps and gorillas physically could not do the kinds of things we can do with our hands - sculpture, art, writing, etc. - because of the way their muscles are attached to their bones.

I can go months without biting my lip, but when I do, why will I bite it in the same spot again three or four times? (pain).	[ "Because that spot swells up and gets I'm the way" ]	[ "Think of your brain like a billion streams of water that flow over the surface of a rock. The more you use a certain stream, the more \"powerful\" that stream becomes by digging away that rock. Now even if you have a nice dug place for a stream, sometimes randomly that stream won't have needed to flow for a while ...
How do the volume settings on your TV and decibel count relate?	[ "they don't, really, other than that the decibels increase as you increase the volume. there is no set relationship between the volume number on the TV volume control and the actual decibels produced. In fact, it varies quite a bit. One TV's 5 setting might be just as loud as another TV's 10 setting, for instance" ...	[ "Seriously.

Why is Rugby still played the way it is (no pads, no helmets)? but a sport like American Football is always in the spotlight about player safety when they already wear types of protection.	[ "Different form of contact, football you tend more to lead with your head were rugby you try and protect yourself more as the tackler. Sports science did a good episode on the actual force applied in a tackles for both. The equipment allows you too use more force because it cushions the blow to the tackler. sports ...

What is at the center of a Neutron Star?	[ "It's difficult to say, because neutron star cores are in a regime (high pressure, low temperature) that is difficult to produce experimentally. Cole Miller at UMD has a nice [page](_URL_0_) on neutron star interiors. I enjoyed the following description of the transition from crust to core: > As the density increa...	[ "sterile neutrinos are a viable candidate for dark matter.

Those are still candidates though, next to the usual wimps or others like primordinal black ...
Why didn't the Romans build castles? Why did castles emerge as the thing to build in medieval times?	[ "Castles were built long before medieval times. There existed fortresses in many of the city-states of ancient Greece (the fortifications of Acrocorinth, for example), in Persia, in China and everywhere else. But, due to their extreme age, we have fewer surviving examples of them than we do of medieval fortificatio...	[ "Building is often done in bulk, dozens of houses at a time, which means you get economies of scale, not just in the materials etc, but in the laying on of services.

How do the physics and physiology differ between running on a treadmill and running on the ground?	[ "Not an expert, but I can only think of 3 differences: 1. Treadmills run at fixed speeds, or at least take a while to speed up/slow down. When you run on the ground, you can change speed however you want. 2. There is air \"blowing\" at you when you run normally, but not on a treadmill. 3. The actual surface of the ...	[ "Processing power. Your IPhone may be good and a marvel of miniaturization, but it isn't nearly as powerful as your laptop.

Since nose hairs act as a filter for germs and bacteria, when you trim your nose hairs are you more susceptible to illnesses?	[ "The relatively large hairs in the nose don't do much for bacteria and viruses. The large ones might be helpful for dust etc. but I'm not 100% on that. The 'hairs' that are important for protection against bacteria and viruses are the microscopic hairs (cilia), which line the rest of the respiratory tract. Smoking ...

Why does something cold and smooth sometimes feel wet?	[ "It's been proposed that your body doesn't in fact have \"wet\" receptors, but instead combines temperature, texture, and pressure to perceive \"wetness\" and form a sort of \"touch memory\" based on that.

What did early Humans do on an average day?	[ "Life wasn't \"nasty, brutish and short\". According to the latest research, hunter/gather societies had massive amounts of free time. If you go back to just the Medieval era, the so-called \"peasants\" could hardly be persuaded to work (for money) for more than an hour or two a day, because they met all their own ...

How have we discovered that water used to exist on other planets and their satellites?	[ "Direct evidence of ice has been observed on Mars. This, coupled with the remnants of fluvial processes on the planet, of which are analogous to many that can be observed on Earth in regions of past water flow, can be taken as yes we have discovered that liquid water used to exist there." ]	[ "We use spectography. Each element absorbs particular colors, so when we see those colors deleted from an otherwise smooth spectrum, we can figure out what they're made of. In the case of." ]
Why don't computers with 2 graphics cards get twice the graphical performance compared to 1 card?	[ "It's all down to the fact that the two cards have to work together. Each card must carry a full frame buffer (the data it uses to render the frame) which means that each card has a replica of the data and not half each, so in essence when you double your cards you are getting zero extra graphics memory. The cards ...	[ "Many missions do use multiple slingshot encounters (aka \"Gravity Assist Maneuvers\"). If I recall correctly, the Rosetta mission performed two Earth GAMs and a Mars GAM. Cassini performed two GAMs past Venus, one past Earth, and another at Jupiter. However, this takes time. In order to pull off the double-earth s...
Why isn't beef bacon more common?	[ "Because it is not possible to make it. Bacon only comes from pigs.

Where does the money dissappear in a financial crisis like the one in 2008?	[ "I believe it was never there. It was money 'shown' on shares of all the worlds companies.

When I'm lying in the dark, why can I not see things if I look directly at them?	[ "> The retina contains two types of photoreceptors, rods and cones. The rods are more numerous, some 120 million, and are more sensitive than the cones. However, they are not sensitive to color. The 6 to 7 million cones provide the eye's color sensitivity and they are much more concentrated in the central yellow sp...	[ "It's the same as the [pinhole effect](_URL_1_).

SSRIs and psychedelic empathogens (shrooms, MDMA) both increase serotonin levels in the brain. Why do empathogens cause feelings of interconnectedness and empathy when SSRIs often cause emotional blunting?	[ "Lsd-25 & other tryptamines binding to the likes of the 5ht2a receptor, replacing serotonin is one of many mechanisms of action. This is completely different from inhibiting the re up take of serotonin in general.
