How is a single-machine software license recognized when it's being used on that machine? Is it registry-tied or IP-address-tied? | It depends. You can do it to Windows key or a GUID which is a bit more complex. You can tie it to an IP address, but that's generally not a good idea because IP addresses are not necessarily fixed. Its better to tie it to physical attributes. This is called hardware binding. For example, your MAC address can't be chang... |
If someone was brought up without being told about sex, would they still know what to do? | Everyone else failed to consider that all the teenagers getting pregnant today are also exposed to huge amounts of sex in the media and their daily lives. If a straight male and female were completely isolated from any mention of sex, then they were introduced to to each other after puberty, it would take some trial an... |
Why do windshield wipers push the water to the drivers side? | The wiper is vertical when it reaches the driver's side, getting more water off than the passenger side. |
Why can't we provide internet by using the same technology that broadcasts television shows? | The TV setup has two BIG perks the internet doesn't. * It's a one-way connection.* The messages are being broadcast to no one in particular with little concern about privacy. Your internet is bi-directional AND intended to be a connection that's potentially private for just you. This results in a **TON** of extra overh... |
How does molecular mechanics work? | Molecular mechanics uses the fundamental forces of physics to describe physical properties of molecules and biological systems. This field is usually used in conjection with computational chemistry techniques since the mathematical construct is complicated and tedious. In my use of molecular mechanics I used guassview ... |
how the reddit frontpage is determined | Here's an attempt at a LI5 answer which says more than "most upvotes in littlest time." Imagine a racetrack for horses that goes on forever in one direction. The start of the track is labeled "Jan 1, 1970 12:00am" and there are equally spaced notches labeled "Jan 1, 1970 12:01am |
Explain how full immersion while living in another country is the fastest way to learn another language? | That's how you learned English and you were fluent in a few years.You pick it up as you go. You have to. I went to a Spanish immersion school K-2nd and by the end of second grade I was fluent in Spanish. The teachers would talk to you in Spanish and expect you to understand. It seems daunting at first but I was able to... |
How do fossils of an action or event get made? | It's fossilized sap. It's basically tree blood, and it flows pretty quickly, and in some cases is almost like water. The insects drown in the stuff while fighting, and the sap hardens over the years. This might be morbid for a 5 year old, but it would be like having a bunch of concrete dumped on you. The concrete would... |
Why is Russia's cyberattack against the White House not a bigger story? | The scope of the breach was very limited. To our knowledge, it was limited to essentially the President's schedule and agenda. There was no classified information and the breach did not extend to more secured parts of the system. |
How are some physical traits able to skip through a generation? | You have two copies of each gene, one set from your father, one from your mother. Each copy is called an _allele_. Alleles can be recessive or dominant. If you have one dominant allele from one parent and one recessive from the other, the dominant allele will be expressed. Only if you have two recessive alleles will th... |
Why the LAPD cooperated so much with OJ during his chase? | In a fantasy world, we'd imagine that LAPD would call the local military base, and have a fighter plane or attack helicopter fly out and disable the bronco with a missile, bomb or some gun. Maybe have a sniper ahead on the road, shoot the driver or engine block with a large bullet. Maybe have an officer in an armored c... |
Why does it cost money to get a domain? And why does the price change for every company and domain ending I use? | The registry fee the ISPs pay is small yet many are greedy and figure most people are stupid or desperate to get the name they want so charge lots more for it. |
Why do big computers have fans but little ones don't? | A fan in phone would make it too fat. So it uses a heat sink instead. When it reaches maximum temp it then bottlenecks itself til working temps ate resumed..It's not only a matter of passive or active cooling. It is also a matter of architecture. The ARM arch, like phones or small computer is designed to have low power... |
Why do military and police forces often side with the corrupt governments when the people rise up against oppression? | Here's the thing: The government pays their bills. It provides a certain quality of life that is, more or less, guaranteed. Everything is set in place, there are people to handle the ins-and-outs of governing, etc. Post-rebellion, *none of those things exist right away*. It takes time for everything to stabilize, and i... |
Why do foods that are bad for you taste better than things that are healthy? | We've evolved to feel rewarded for certain chemicals and compounds because they are vital for our survival. However, in modern society, we can get them in abundance. Our bodies haven't evolved a way to say 'hey wait, that's way too much of a good thing.' So we over-consume and the excess has deleterious effects on our ... |
what is the alternative to a two-party system? | A multi-party system. For an example, look at Canada. We have several parties, in fact as long as you are willing to pay for it, you can start your own party based on any political belief. We have the Conservatice party, the Liberal Party, the Blocques de Quebecquois, New Democratic Party , Green Party, etc. We even ha... |
Why do I (and others) talk to themselves? | Conversing with one's self has long been a common practice amongst humans. It puts our minds at ease when things like taxes, bills, work and life's other discrepancies get us down. Often times, we like to converse with ourselves in order to play out a scenario in our head before an event whether it be huge or insignifi... |
Why is it after all my ex has put me through, one conversation can undo a ton of work I've made in getting over them? | I cannot emphasize this enough: The human brain is basically six pounds of fatty Jello. The fact that it is sometimes capable of mathematics and rhetoric does not make it rationally designed; natural selection favors survival and reproduction over logic and happiness. Bio: Strong pair bonding makes sense for animals li... |
Why does my stereo measure volume starting in the negative decibels? | "Decibel" or dB isn't a unit of _URL_0_'s a way of measuring things with large ranges relative to some arbitrary value. dBFS is the measurement for digital signals, and 0dB is the maximum. dB V is the measurement for analog voltages, dB SPL is the measurement for sound pressure level in air. All are different and mean ... |
How does Apple know whether or not a charging cable is "certified"? | There s a chip inside the lightning cable that tells the phone that its a legitimate chip approved by apple, if the phone doesn't see this, then its not legit. Yes it can be hacked, thats how some knockoff cables from China were introduced. |
How come it's harder for countries in South America and Africa to modernize as compared North American, European, and Asian countries? | South America wasn't founded on wanting freedom, it was colonized to extract resources and enrich its colonizers. Then there's foreign interventions in South America. Here's a [map] of US interventions. Then there's home-grown problems like class divisions. |
Why are most popular websites created by Americans? | English, plus the largest portion of internet traffic is American, so anyone who can appeal to the American market will find it easier to make a popular website.In Asia, most countries have either limitations on internet usage/content, or the internet is not widely used enough to encourage website creation. There are m... |
Is there a reason why my leg bounces all the time when I'm sitting down, and I hardly ever notice? | Its a way your body copes with blood pooling in your lower extremities owing to gravity. As you are involuntarily shaking your leg, the major veins that are embedded in your leg are being squeezed by the surrounding musculature and this facilitates blood to flow upwards.The ball on the bottom of your foot in the middle... |
How does outside/fast lane of a motorway get congested to the point traffic is at a standstill? | The scene. Nobody wants to drive in the slow lanes because they're full of lorries so they're traveling at 60. So the next lane in gets full of cars doing just a bit more than the lorries maybe 65 to 70. So you've only got the fast lane to overtake in. Car doing 70 overtakes long line of cars in the middle doing 65 and... |
When people drink alcohol, cravings for and use of cigarettes is increased greatly. Is there a scientific basis for this, or is it purely habitual? | Alcohol is a depressent, nicotine is a stimulant, the two go very well together. Alcohol also lowers inhibition and impairs judgement, meaning you are more likely to give into a craving, and less likely to care about the implications of doing so . Mixing things that slow you down, with things that speed you up, is seen... |
Why is Disney allowed to purchase Fox Entertainment? | It has not been approved yet. It was just announced today. You can always announce it, it does not mean it will get approved. Actual approval likely wont be settled for 1-2 years from now AT & T-Time Warner is currently not approved either, and may not be resolved until March - July depending on specifics. |
[America] Why Do Medical Fundraisers Still Ask For Full Cost Of Treatment Instead Of Insurance Premiums? | I 've not seen these things you are talking about, but anyway Buying insurance does not pay for the costs of treatment already incurred. If you get hit by a bus, it unlikely the Elks Lodge is going to buy you insurance during the ambulance ride. And buying insurance is generally restricted to "open enrollment periods" ... |
Why do puppies smell funny? | Dogs produce an oil naturally that has a slightly yeasty smell, . This oil is produced to protect the dog's skin and hair. Most often, dogs end up picking up bacteria on their skin when they are outdoors. The combination of the oil and bacteria produce what many call the "wet dog smell". Dogs don't sweat over much of t... |
Landing on Jupiter? Possible? | There is no conclusive evidence about Jupiter having or not having a solid core. The scientific consensus is that it PROBABLY does a solid core, surrounded a liquid metal layer and then finally a gas layer. Your spacecraft would probably be crushed fairly early on, or attacked by the nasty gaseous atmosphere, or be des... |
How is the Michelson-Morley experiment evidence for the constancy of the speed of light? | First you need to know about what was called aether. In the past, people thought light were waves through something called aether, that sourrounds us all similar to air, but only that it exists everywhere. Now since the Earth is rotating around the sun, we must be moving through the aether somehow. That means that, whe... |
How could I successfully argue with co workers when they observe near record low temperatures and declare, "global warming doesn't exist." | The correct term is climate change- it is not about just warming but a shift toward more extreme weather patternsAsk them what "global" means. It's been pretty damn hot in Australia this week.Because the record lows aren't as low as the record highs are high. |
Why is the synaptic vesicle not connected to one another? | > Would it make any difference if they were connected to each other? It is useful for a nerve signal to sometimes be triggered and sometimes not. If they were directly connected then you wouldn't really have an action potential to build up and "jump the gap", it would just be always on which sort of defeats the purpose... |
How are few companies able to own majority of the brands I use? | this is end game capitalism. lets say you have 100 companies all in one area. some do well, some don't. the ones that do well might buy out the smaller ones or the smaller ones go out of business. eventually once they become big enough, they start buying other smaller companies that retain their brand, since customers ... |
Why do large companies sign a 10-20 year building lease when that comes close or exceeds the building value? | Often it's a cash-flow decision. Purchasing the building outright costs a lot of upfront money and adds uncertainty to the end of the 10-20 year time frame if the company wants to move somewhere else. They would either be stuck with a building they didn't want, or have to sell at a price they can't predict. Signing a l... |
What exactly do courtroom artists do, and why are they a part of some trials? | Especially in high profile cases people want to know what's going on. Nowadays if become more common to televise events. But before this was the case Judges often banned media like pictures and video in thier courts. So courtroom artists would sketch parts of the precedings for newspapers to use. |
Why Aren't Third Party Candidates Allowed to Debate? | Right now, the debates are only for candidates of a certain party. When the parties have nominated their candidates, third party candidates would be able to debate if they polled high enough.What do you mean by that? The debates that are currently going on are for the 2 main US parties to decide who their candidate wil... |
How do floors get mopped, garbage cans get emptied, plumbing get repaired etc. in top secret areas? Are there janitors with high level security clearance? | Areas like that have "clean desk" policies where everything has to be secured in locked drawers when you are not at your desk. If it is somewhere with constant activities then the people there take their trash to somewhere outside the room where it gets collectedThe area is first cleared of all classified material. Doc... |
Why do objects at a distance look so much further away in photos? | You used a relative wide angle lens. It has a wider field of view than your eyes so things appear farther away. You could use a more "normal" focal length to make things appear as you see them, or a longer lens to make things appear closer.Isn't there a psychological aspect too? Our brain knows we are focusing on the s... |
what does it mean to label China as a "currency manipulator"? | There currency exchange rate is set by the government. They set it so you can buy a lot of yuan for your dollar. This makes their exports cheap since when you buy their exports you pay in yuan and if you have dollars you have to exchange dollars for yuan and you'll get a lot of yuan for the exchange and so you can buy ... |
Separate Facebook Message App - Why the mandatory breakout separation? | It solves the problem of having to deal with a large amount of code. Something the size of the Facebook app requires a large number of programmers to maintain, and programming gets harder the more people you have to add to a project . Having multiple smaller projects allows them to improve both products faster.Couple o... |
What is a Fibonacci Sequence? | A sequence of numbers, starting with 0, 1 where every subsequent number is the sum of the two previous numbers. 0 1 0+1=1 1+1=2 2+1=3 3+2=5 5+3=8 8+5=13 and so on. Hence, the Fibonacci sequence starts 1,1,2,3,5,8,13 Edit: realised 5+8 != 11. I'm an idiot. |
How do investors pick franchises and are they preferable to starting a business on your own? | Investors pick franchises based on what they think will be the best fit for where they want to operate their business. Several things come into play, such as the cost of the franchise, the amount of support they get for that money, the appeal of the product in that market, and how much competition there is for that pro... |
Why is it that some people can learn equations and concepts when examples are involved ie: physics/chemistry but struggle with similar ideas when examples aren't involved ie: trig/calc/algebra? | There have been many theories of learning which categorise people into different groups depending how they learn. Pretty much all of these theories have been disproven. However, one thing that *is* known is that, however hard it is to categorise people, we *do* all learn differently! Some people like to see things writ... |
why do I feel sick when I read in a car? | In order for a person to estimate his location, the brain combines information from a variety of sources, including sight, touch, joint position, the inner ear and its own expectations. The inner ear is particularly important because it contains sensors for both angular motion and linear motion . These sensors are call... |
When in flight why does the propeller of an airplane look like its moving really slowly? | This is called aliasing. Basically your eye cannot sample light fast enough to follow the actual speed of the propeller. Instead it samples at a rate, then pieces together the images to produce movement. If the properller spins 1.1 times between images, your brain makes the assumption the propeller moved 0.1 revolution... |
Why does vegetable oil work as a substitute for traditional fuel in a diesel engine? | Diesel engines work by compression ignition; you add a small amount of hydrocarbon fuel during compression, it eventually combusts and the energy of combustion raises the pressure and drives the piston downwards, producing power. However, this autoignition isn't a magical property unique to diesel fuel; **every** hydro... |
Is there any merit to the idea that exposing yourself to germs strengthens your immune system? | Your immune system, every time it beats off an infection, stores information about that infection in it's "memory B-cells." That way, if you get reinfected, your immune system can say "aha it's you again! I remember your secret weakness from last time!" instead of having to figure it out all over again. It doesn't have... |
Why does my skin itch when i've been sweating and touch grass? | Grass makes very small cuts on the skin, and when those cuts are contacted with liquid it itches. It's like salt in a wound, but much smaller. |
How does my fingerprint scanner on my iPhone work through a plastic bag? | Because it's not a fingerprint scanner, it's just a camera. Advanced fingerprint scanners use high resolution CMOS sensors, pressure and temperature sensors, and a myriad of other tricks to detect an actual finger against a simple printout of your print. The scanner on phones and laptops, and other cheap consumer scann... |
The reason why NSAIDS are ineffective at reducing symptoms of diseases like Psoriasis? | Not 100% sure, but I would say that's because Psoriasis is caused when your immune system ins't working properly and the chemicals involved in psoriasis are not affected by NSAIDS |
why it always seems like people wake up before the best part or climax of their dreams. | Until a better answer shows up, I believe I 've read on this very forum, that it has to do with the fact that the "best part" just so happens to excite you so much, that your brain activity increases and you therefore begin to awaken. Another aspect may be that you don't remember dreams in which you didn't wake up duri... |
How does bracing reduce the impact during a crash? | It doesn't reduce the impact, but it gives you some warning that an impact is coming and allows you to protect your vital parts . While there have been cases where asleep/unconscious people have survived impacts that have killed others, there is often more to those stories than initially presented. Case in point: old c... |
How can someone be immune to the laws of a country simply because they have diplomatic immunity? | Because the country that they represent have been extended that courtesy for their diplomats by the host country. It's a common arrangement so that diplomats don't get blackmailed by local police or politicians. The host country can always expel a diplomat if they don't want them there. And the diplomats country can wa... |
Why do the creatures at the deepest parts of the ocean look so different from that species we normally see? | A huge pressure. For anything to be able to withstand it you need either incredible skeletal structure, or massive skin and muscle mass. The former is almost non-existent, if it exist it's mostly in small organisms such as crabs, etc , the latter is more common. Remember [this] guy this is how he looks when he is not u... |
Why laptops still use differrent chargers, and why they dont follow the example of the mobile phones? | $$$$$$$$$$$ Same reason apple uses its own cords. You have to buy them from the company that makes the laptop.Yo ho ho! Yer not alone in askin', and kind strangers have explained: 1. [ELI5: Why don't all laptops use the same power cord, like happened with cell phones? ]1. [ELI5: Why are laptop charger cables not standa... |
Why and how are power plants designed so they can't power themselves? | The plant isn’t technically incapable of powering itself—it’s incapable of running without a grid connection. That might sound like a distinction without a difference, but the plant requires a connection to the grid not to *receive* power from the grid, but to *dispose* of power on the grid. The nuclear plant requires ... |
If Physics states that we don't actually touch anything, how can we taste and smell? | We don't really touch things, but that doesn't mean they don't interact. Magnets, gravity, electrical charges all do not physically touch things, but they interact because of the force emanating from them.Just because the atoms in our body don't physically contact other atoms doesn't mean that there's no such thing as ... |
How did people figure out precisely which direction to build a railway in before GPS and modern technology? | You'd be surprised how accurate tools like sextants are. They were around for a while before we started building railroads.Usually the railway as build along an existing feature, like a wagon trail or a river. If you know how to get somewhere by foot or horse, you know how to build rails to it. Also, you can accurately... |
What allows our brain to "focus"? | The brain has a subconscious filtering system that decides which things are unimportant and which should be passed on to our conscious mind. |
why does resting my hand between my thighs warm me up? | You have a lot of nerve endings that control your hands. Perhaps warming them *tricks* your brain into thinking you are more warm than before. Check out this [homunculus] to see the brain proportion that is dedicated to controlling certain body parts. As you can see, lips and hands require a lot of nerves and brain to ... |
What makes a substance nutritious? | A subtstance is nutricious when we can extract energy from it. That substance can be carbohydrates , fats, and amino acids from proteins. The body modifies these substances into one of the products that can be used in the so-called Krebs cycle. The Krebs cycle is a series of chemical reactions that releases stored ener... |
what is the difference between vague, ambiguous (semantic), ambiguous (syntactic), ambiguous (grouping), overgeneral, or both vague and overgeneral. | Kind of confused about what you're asking for. Is it assignment-specific jargon? The difference between 'vague' and 'ambiguous': Vague - Lacking detail but has specific meaning. e.g. Joe is tall. How tall? Joe is tall compared to what? Ambiguous - Several meanings or open to interpretation. e.g. The concert was cool. D... |
what is magnetic flux? | Say you have 100 water hoses stacked in a square and pointed at a house. The window is open. On the hoses hit the window go in the house, the rest just hit the wall. Magnetic flux is when you take the magnetic field and multiply it by the area of a given thing, say a hoop. The magnetic field is like the water hoses. Th... |
why isn't single serve coffee sold in tea bags? | Didn’t Folgers used to make “coffee singles” in the past? I’m not sure if it was instant or supposed to act like a brew, but I’m almost positive I’ve seen something like itIn Australia you can buy coffee bags. These ones are sold everywhere. _URL_0_Coffee and tea diffuse differently, tea diffuses through simple immersi... |
Why can we build 1TB SSD's but not 1TB of RAM and cut out the storage? | We can make a terabyte of RAM but it would be really expensive and couldn't store data when the computer was off. Also we really don't need the incredibly fast access for the vast majority of that data.Totally different systems. Ssd are slower to access, and can store data without power. Ram is a super fast access, but... |
Does a gas giant actually have a solid surface? | The "surface" of Jupiter is gaseous hydrogen.\r_URL_0_\r\rWhat would happen if you went "on" the top of Earth's gaseous atmosphere? You 'd fall, right?\r\rJupiter is much more massive than Earth though, so you 'd fall even faster, and probably burn up from friction with the atmosphere before anything more interesting h... |
Where do birds keep their bone marrow? | According to our friends over at /r/askscience: > Birds have bone marrow it just doesn't intersperse through the central region of bones like in humans. Avian bones aren't hollow in the sense that they're like straws with absolutely nothing inside them. There are networks of structural fibers that help give their bones... |
How does evolution explain an animal developing the ability of venom attacks? Like a Platypus? | As [this] link will tell you, many venom systems started out as something entirely different whether they be digestive enzymes, proteins to help fight bacteria, etc. A mutation occurs and suddenly that enzyme/protein/etc is present in the mouth/claws/etc, and it gives them an edge to catch prey and just generally survi... |
Why are games being exclusive to a particular console "bad" and why is this exclusivity deal Netflix has secured "good" ? | You're currently comparing two things in different ways. I understand the confusion but you're just getting it a little bit twisted. I'm not a gamer, but here goes my attempt at an explanation. 1. A game being only available on ONE platform is bad for the game due to the fact by only being on one console, the potential... |
What gives massless particles a 'speed limit'? What stops them from traveling faster than 299,792,458 m / s? | Simply put, we don't know. It's a very well documented and solid physical constant, but why that happens to be the universal speed limit isn't clear. There's some speculation and models that attempt to describe it, but nothing verifiable as of yet. |
Why can I remember the conventions of a new programming language or the methods of a new library with ease but spend hours memorizing facts in biology class to no avail? | As a fellow student learning programming with ease and dying in biology, I feel your pain. I can't possibly explain for you without speculating, but for me it's because of the style. Biology is a very fact-oriented thing. You either know what allopatric means, or you don't. And you never get to actually use it, because... |
Allergies; and why the body develops them. | Your body's immune system often causes your body to do less-than-desirable things. For example, when it's fighting a cold, it's your immune system, not the cold virus, which causes you to have a runny nose and sneeze lots. When something gets into your body which doesn't belong there, your body's immune system recognis... |
Humans mated with Neanderthals and have some Neanderthal DNA.What prevented their mating with other archaic human types? | It may have happened. It is hard to prove. DNA degrades with time. Only in special circumstances, cold dry caves, does some DNA survive for thousands of years. To prove it you must have DNA from the different humans to have lasted since then. It is extremely unlikely to find DNA much older than what has been found. Jur... |
why does Adobe Flash Player need to update so much? | Adobe Flash is, by Internet standards, a very old format. It comes from the days where every byte and every CPU cycle was very important. This meant that it used various tricks to save space and computer effort. The programming to work with these tricks is complex, and complex programs have places for bugs to hide, and... |
Is it better to brace your body or stay loose in an accident/fall? | Obviously every crash is different and some things will work better in one situation than they would in another, but the brace position in an aircraft crash, or bracing against a car seat have a very specific purpose. In any collision there are multiple impacts. In an aircraft crash there is the impact of the plane hit... |
Why can e-cigarette companies advertise on TV while traditional cigarette companies can't? | E-cigarettes don't have tobacco in them, they're a smoking accessory. It's like advertising a cigarette lighter |
Why I can't look in different directions with my eyes. | You can. Back in 2006 while doing "How to [cross] just One Eye" and "Speak with an Echo," I got ambitious and tried inducing [MartyFeldman-o-vision]. I had some fresnel prisms left from a failed toy design[1] which only deflect a couple degrees. Mount on eyeglass frames to bend light inward. They gave double vision, bu... |
Why does western society treat sex as something taboo? | This isn't really a concept question. Europe and America both "western societies" have different views on sex and display of it. US views on sex is still largely influenced by our Quaker and Puritan heritage. Your question needs some clarification and best for perhaps r/askhistorians |
what actually is that feeling when you're falling in a dream and you wake up? | The falling feeling is from a hypnic jerk. Your muscles may twitch or spasm and your mind is trying to make sense of it. You think that you're falling. I believe the heart beating and the shortness of breath is an emotional response. It's kinda not really clear why this happens. Even though you are sleeping, there is a... |
Why is it more quiet when it's snowing? | Many things at once make this happen: 1) Snow on the ground absorbs the noise around us, where as the hard surface of the roads bounce it off. Just like a room with carpet and curtains does not echo, but an empty room with floorboards does echo. Absorbing the noise makes it quieter. 2) Snow is soft and makes sounds qui... |
what exactly is the purpose of dreaming? | No one's entirely sure. Some popular theories: --it helps us sort through the events of the day and create memories accordingly --it helps us work through the emotions of the day and reach equilibrium --dreams don't serve any purpose; they're just a consequence of some other process These aren't necessarily contradicto... |
Why does water feel much colder in your mouth when chewing mint gum? | The ingredient in mint gum that gives that cooling sensation is called Menthol. The tongue can not tell the difference between Menthol and actual cold temperatures so that's why they feel the same. As a side note, capsaicin is why our mouths feel hot. Again, because this chemical tricks our tongue into thinking, it's o... |
NFL followers, why are there so many people on the sideline while the game is being played? What is their role? Novice at NFL here. | Media people, cameramen, sound people, the other 80odd players not on the field, the coaching staff, the athletic trainer staff, the medical team, NFL officiating crew, security Add it all up and you usually have several hundred people on the sideline of a typical NFL game. It takes a lot of people to make that kind of... |
Is it possible to become ambidextrous? | I highly suggest posting this over at /r/askscience to avoid hundreds a meaningless anecdotes being your answerWith enough practice, yes. I suggest tying your dominant arm to your torso for a couple weeks.I'm going to say no just to dissuade you from attempting to join our ranks.I had a step-grandparent who was natural... |
how does people you may know function on facebook work? Do people who have visited my profile pop up there? | Do you have their phone numbers or email addresses and have ever used the feature that allows Facebook to search your contacts for potential friends? If you've done that they will show up in your recommended friends. Sometimes it seems to be so sensitive as to suggest someone who I have only contacted once.People who a... |
How did some animals (lizards etc.) get an ability to regenerate limbs evolutionary? | All species have the capacity for regeneration, some to a higher extent than others. What you are referring to is called autonomy and in most cases it was developed as a defence mechanism that allowed an animal to escape by sacrificing a limb and then regrow a substitute one . A good example of this are certain lizards... |
Why, for some stereo speakers, does one stereo cut out before the other one when adjusting the volume to a very low setting? | Because the device is probably using a stereo potentiometer. One of the quality differences between cheap and non-cheap multi-channel potentiometers is how accurate the tracking is on the two channels. |
Why do marathon runners tape their nipples? | They chafe against your shirt, they can even bleed. I didnt really take that seriously until I ran my first half marathon. It is a thingChafing. Some fabrics combined with continuous friction over one of the most sensitive parts of your body is not a good mixture. |
Why do our voices sound robotic when we speak into the fan? | Because the fan blades reflect the sound back at you, like any hard surface will. The difference is the fan has gaps in it that are are whizzing past. So you're getting hard surface, gap, hard surface, gap and so on many times a second, and your voice gets reflected back with a similar on/off/on/off pattern. Your voice... |
What actually prevents something from continuing to grow once matured and does any species max growth increase over the generations? | Genes usually stop growth when a pre-determined structure has completely formed. That is called determinate growth. Indeterminate growth means that the animal will grow all throughout its life, this is common with fish, mollusks and reptiles. |
Why is Broadway and musical theater in general associated with homosexuals? | I think that a lot of the aspects of theater in general are socially viewed as feminine, adding a sort of femininity to male actors/ theater professionals. Also, it may have been influenced by Castratos in classical opera/other classical performance settings but that's 100% speculation. |
