Why do we perceive those who don't speak the same language as us to be less intelligent? | I've always noticed that people who are newly speaking a non native language, often don't have the tools to covey wit. They aren't stupid and do have witty, clever thoughts, but being able to put that into language is one of the final things you learn when grasping a new language.In my personal opinion,because they can... |
Why are there so many checkout lines in grocery stores but never enough employees to fill them? | Not sure.. I always have to use the self checkout because no one is at the others.. I'm convinced that people don't work there.. Everyone is just a customer helping other customers..Customer Service Manager here. For our store, there are a number of factors involved that would account for the long lines, but a major on... |
Why are companies like Google and Microsoft always under Anti-Competition scrutiny, but Apple is not? | > 3) Maybe I just dont understand anti-competition laws - e.g. the famous Microsoft IE case - there was nothing preventing users from installing their own browser and setting it to default, and Windows is Microsofts product! Why should Microsoft have to support the use of other software if they dont want to? Having mar... |
why do you wake up sometimes and feel like you're paralyzed and can't move, even though you're aware you're awake? | It's a natural part of sleep for the body to be paralyzed while dreaming so that we don't act out our dreams and hurt ourselves. At the end of sleep the paralysis should end, and then we should wake up, but sometimes the timing gets messed up and we wake up first. |
Why do people buy houses instead of rent? | Most rental houses have stipulations on what you can and can't do to the house. If you want a specific type of house, one that doesn't regularly exist, the your only option will be to build that house yourself Also, long term, you could potentially pay less buying a house than you would renting it for the rest of your ... |
Some questions about electricity and electrical power. | > How does current work/is estabilshed in DC ? Sorry, what are you asking? How do you provide generate direct current *without* using batteries? If so, then the answer to this is the same as the answer to: > Also how do you make AC into DC? Generally you use a [rectifier]. Basically, there are parts called diodes which... |
why don't the laws against opening others' mail apply to digital content? | Has anyone considered that min the US, the postal service is a federal entity? So of course the government will have laws to protect it. I bet if the US had its own email domain, that'd probably get protected too. Gmail and the like are private entities. No more entitled to this legal protection than their employees ar... |
The purpose of the turbines you see in the top areas of road tunnels | As most people have said its to do with air flow to remove fumes. You'll also see it in basement car parks where natural ventilation isn't possible. It's harder to exchange a volume of stale air/fumes there due to corners as there's not clear path through so vortex fans are used to direct it/increase flow rate/volume. |
Why everyone loves The Beatles so much...? | I'm of the opinion that they've written some of the greatest songs across a myriad of genres. I can't think of anyone who has done the quality of work that they have both within straightforward pop rock to more complex tracks like A Day in the Life. So my argument is that it *is* a taste thing. Just curious, who do you... |
why/how does almost every nation have different languages, measurements, etc but the whole world uses same measurements of time (seconds, minutes, hours) | After reading through most of this thread, [pretty much every answer given here can be found in this one section of the Wikipedia page 'Second Short version: no one knows why it first started or where, but it's been that way for thousands and thousands of years. My totally uneducated guess is that it's a fairly typical... |
Every human on the planet spontaneously vanishes, and a hundred years later, aliens arrive. Would they be able to find out about the internet? | What you mean to ask, would the internet still be accessible, the answer is no, the equipment would not last without maintenance. Some automatic systems would continue to function for some time, but without people to perform hardware replacements, it's likely that most computer equipment would die within a decade. As m... |
A deer can eat poisonous plants like rhoderdendrons because they don't have a gall bladder. When a doctor removes a humans gall bladder, are they too able to eat poison without feeling ill? | Gallbladder has nothing to do with breaking down toxins, it's sole purpose is to store and concentrate bile that was made in the liver . Toxin management is the liver's job . If it's true that deer can eat poisonous plants it's because they have a specific enzyme that is able to break the toxins down. Different animals... |
Why do we always portray extraterrestrial life as way more advanced than us? | That's not even the case. Simple rule: If they find us, they are more advanced, if we find them, we are. Take for example Avatar, they fight with Bow and Arrow against modern weapons. |
If an electrical outlet (120 volts) can kill you, how come a taser (50,000) can't? | A feather dropped off a sky scraper won't hurt you when it hits you. A sack of bricks dropped from a short building might kill you. |
What is a Master's Degree and What Does it Signify? | A master's is post graduate education after a Bachelor's. It's basically, the same stuff you learn in bachelors but just more advanced. You don't need the Bachelor's degree for a Master's, but you will need all the underlying knowledge you would have obtained from the Bachelor's in most cases. So either you have the ba... |
why is suicide generally not accepted? | I feel like everyone has the right to kill themselves if they truly want to it's your life. Yes your leaving people behind and they might miss you but do you think that someone ready to end their life hasn't considered that already? Newsflash they have and if they still want to do it who is anyone to say that they shou... |
Why do people still use handkerchiefs | I actually had the opposite question in a discussion with my wife the other day. Both she and I carry a handkerchief in our coat pocket throughout the winter and we couldn't understand why more young people don't use them. The most obvious benefit is you buy one or two and you're set . In addition to being less bulky t... |
Why do Americans say "twelve hundred" but not "ten hundred (rather than one thousand)"? What's the difference? | I'm puzzled by the answers so far.. I always thought it originated in military time, where hours 1-23 are expressed as hundreds. Do you also say 35 hundred ?", 'For the same reason we say 101 as "one hundred and one" but don't say 99 as "ninety and nine" Just the way we are taught. |
why do trains usually have engines on the front and back rather than just the front or back? | Trains are designed to be as efficient as possible, which is why they have steel wheels on a steel track, to reduce the rolling resistance, and as a result, they actually don't have a great deal of power available to them. Most big freight trains have a power to weight ratio of less than **one** horsepower per ton. Com... |
Why didn't this gopro burn up when it fell from Earth's atmosphere? | Because it was traveling very very slowly. Meteors hit the atmosphere at hundreds of thousands, sometimes millions of miles per hour. This gopro hit the atmosphere at practically 0 miles per hour. It would not have been falling particularly fast. It hits terminal velocity fairly quickly. A gopro dropped from space won'... |
How does my body filter out the stomach acid that mixes with the water I drink, so I don't pee acid? | When you pee, that's not directly coming from your digestive system. As fluid moves through your digestive tract, your body absorbs what it needs through the walls of your intestines that water circulates with your blood to get where it needs to be. One of the places water needs to be is in your kidneys, where it helps... |
Why does it feel like time goes by faster as I get older? | It's the theory of relativity. When you're on a bench waiting for a bus, the time goes so slow. But when you're sitting with someone you really like and having a good time, it seems to go by so fast. |
Why did the cost of US college tuition skyrocket? | [Here's the last 25 years.] [And 20 years in graph form.] It has gone up, but not as much as the talking-points suggest. A large piece of the puzzle is that no college wants to advertise low prices - it makes them seem cheap and less desirable. Advertising higher prices makes a uni seem exclusive and desirable, even if... |
Why are most of the foods that taste good bad for you? | It's all in the preparation. Also, most junk food will leave you feeling like junk if you eat too much of it or too often AND you are not 17. |
Why do fashion/clothing models always look pissed off? | you'd be pissed too if your only meal each day was a handful of raisins, a coffee and some laxatives. |
How do I know the color red I'm seeing is actually the same color red you are seeing? | You don't. Color is a product of three things. 1. The object. 2. The viewer. 3. The light. A change in any one of those things essentially changes the color being viewed. |
Why do people tend to feel cold when they are depressed? | Why do you think this is the case? Because I'm not aware of that as a symptom. |
Why the Big XII is falling apart | It's because Texas smells bad. Now that the joke is out of the way, here's what's happening. Colorado and Nebraska split because they were realizing that the power in the conference was in Austin. They wanted none of that and left. Then Texas came up with the Longhorn Network. There are two problems here: 1. No revenue... |
What was the point of nuclear torpedoes? | I think that many are missing the OPs point. Yes, the torpedo would be effective as a tactical weapon to sink 1 ship but at what cost? the elevation of a conflict into a nuclear war over the sinking of 1 ship? I don't see how it would be worth it. |
What is the Holy Ghost? | I would like to add that from the muslim's standpoint, the holy ghost is none other than angel Gabriel, since to them a single God is mightier and is capable to do everything and anything without the need to be trinity or to live on Earth |
The three seashells, as referenced in the 1993 motion picture Demolition Man. | I've thought long and hard about it and there's no way to use them without being woefully inferior to any kind of toilet paper. It's inflexible - you'd never be able to clean your taint. In theory, with the right kind of shape and some manual cheek-spreading, it could potentially provide superior surface-to-surface con... |
Why is gigabit internet useful? Most hard dives can’t write information that fast so why would Someone need Internet that monumentally fast? | It's all about bandwidth my dude.. if My wife is streaming something, and my son as well, I still want to be able to play a game. Each act takes up a portion of the available bandwidth. And it all isn't going to be used just for the same computer. Now, this is a rare occurrence, and often times when there's a lot of de... |
Why is standardized testing still the norm when a lot of studies say that it is negative for the learning system? | Science is based on numbers, and to make education better you want to boil it down to a number, even if it's not a perfect measurement of what you want to improve. Then you can do experiments to see if there is a way to improve education to improve the number. Or if there is a way to change how you measure the number t... |
Why is listening to a song in my head not as satisfying as actually listening to it? | Your brain is capable of remembering parts of the song, but not all of it. You can probably remember the lyrics, the more standout solos, and maybe one of the instruments. All the more detailed stuff, the other instruments, the exact way the song is sung, the fine details you don't remember, so when you actually listen... |
Will the economy ever recover to the point where it was 20-30 years ago when our parents would work 40 hours a week and be able to buy a house and support a family? | The economy isn't necessarily getting worse. For example, [disposable income has increased dramatically] over the past 50 years. Two things in particular are getting worse. One, the cost of buying or renting a place in a major city. Two, the collapse of the working classes. The loss of manufacturing jobs, customer supp... |
Why is it impossible to film something in real life for virtual reality? | I have an 8yo brother, too, and this is how I'd explain it to him. *Playing a VR game* and *making a VR film* are very different things, even though they share a common medium. The 360 degree videos on YouTube are made with a 360 degree camera. They're not video games, just videos. You can't move around in a movie, rig... |
How come it's so easy to tell the difference between games made in different engines | Different engines have different little details that give them away when you've looked at enough games. A casual observer won't be able to tell what engine, say, Titanfall ran on. I could tell you from a first glance it runs on Source because it has very Source-y physics and the way its subtitles appear on the screen .... |
Why does string theory matter? | It is a theoretical framework that potentially allows for a 'Theory of everything' by incorporating gravity, and as such potentially approaches a more fundamental description of existence. And of course, the more correct our description of existence is, in all probability the more capable we are of dealing with and man... |
why were zeppelins ever used in warzones in WW1? Weren't they really easy to shoot down, killing everyone on board? | No, they weren't. Zeppelins were actually notoriously difficult to take down for much of the war. Zeppelins were built by having a rather sizable number of functionally independent gas bags that held the gas used for lift. What this meant was that puncturing a few would do rather little to bring the ship down. Furtherm... |
why does tv signal manage to have no buffer when you watch tv, while internet videos buffer a lot ? | Digital television does buffer. The data is transported in DVB format in Europe, and ATSC in North America, and parts of Asia. It is meant to be played back close to real time, but the receiver needs to buffer at least enough to synchronize the audio and video components of the stream. The audio and video streams are s... |
Why cant we just stop media outlets from covering terrorism? Wouldn't that effectively make it pointless? | I've always watched the news before work and at 6pm, this year I decided to stop watching it, I unfollowed news media outlets on social media and to be totally honest, I don't feel like I'm missing out on anything. |
How can the Sun's gravitational pull be strong enough to keep Pluto in orbit but not just pull Mercury into it? | Some great answers here. But a simple ELI5 answer is that it's not only possible for an object to fall towards a gravity source , but it's also possible for an object to fall AROUND a gravity source. Even though Mercury is a lot closer to the Sun than Pluto, they both still fall around it. In fact, it would be possible... |
How can or why would someone consider themselves being transgender without being pre-op or post-op? | Are you asking why someone who is transgender doesn't have surgery? I would imagine a host of reasons, money, not wanting to undergo that kind of bodily trauma, etc. |
What's the difference between a 10Mb/s connection and a 100Mb/s one when the "bits" travel at the speed of electricity in both cases? | Assuming we're talking about modern fiber-optic internet, then the data travels using light so it travels at the speed of light . As for the data speed, it can vary greatly depending on a number of factors. * Quality of the cables* Type of cables* How congested the line is, i.e. is it peak time so everyone is using the... |
What are the primary arguments *against* the Affordable Care Act (Obamacare)? | As someone in the insurance industry with a well known brand, it's obvious that most of the commenters here have no clue what is getting ready to laid on the population here. You focus on the employers with 50 or more employees, but it's going to hurt the guys like me who have an office of 10 as well. Did you know we p... |
Why is it that maps are all oriented with North at the top? | For the record, they are not always oriented that way. In Japan, it is popular to orient maps 'forward-facing'. So when you stand in front of the neighborhood or train station map, something to the right side of the map is to your right, left side of the map is to your left, top of the map is directly forward, bottom o... |
ELIV: Can someone please explain to me why BitTorrent isn't illegal? | BitTorrent is just a convenient technical solution to the problem of getting bits from point A to points X, Y and Z. Rather than send the same things to X, Y and then Z, just send them each a part and have X, Y and Z share the different parts they've received amongst themselves. It's faster, cheaper, better for all. Pi... |
It seems like every major news website, or newspaper find its sources from Reuters, then why don't people go read news from _URL_0_ directly ? | Votre anglais est presque parfait, sauf que vous avez oublié le 'does' dans la troisième phrase. Sorry, I like practicing. :) |
How does someone go about changing their identities and their families, as shown in Breaking Bad and Goodfellas? | There is a book about that called [How to Be Invisible.] Completely changing who you are is illegal unless you are under witness protection, but there are a lot of ways you can legally hide who you really are by using fake names and addresses and things. It's an interesting book. |
why does Internet Explorer get made fun of so much? What exactly makes other browsers so much better? | Um, let's see. Other browsers are faster to load and less prone to viruses. They have fewer security flaws and are generally smaller CPU hogs because they aren't so closely linked to the computer operating system.Internet explorer has a long history of not displaying web pages correctly, crashing, and being DANGEROUSLY... |
Why do all (or most) languages capitalize the first letter of a sentence? | I haven't read through all of the replies, but from a graphic designer's perspective, I'd say it's to make it easier for our eyes to notice when a new sentence has begun, or to find the beginning of a sentence. |
Why did the U.S. send a rescue mission to Syria for James Foley and yet not sending a rescue mission for another American citizen named Kenneth Bae who is detained in North Korea? | The situation is less fluid in North Korea. The DRPK is just waiting for an opportunity to deploy its army against the West; currently we haven't given them a reason to do so, but they've been prepared to go hit US and allied targets since the end of the Korean War. An incursion would push them over the edge. |
Why do some cities have their own fire/police department, sheriff department, while others has the county police/fire? | There's always going to be a primary responding agency -- city police, county police, or sheriff. No cities have their own sheriff -- that's always at the county/parish level. In most states, police are at the city level and sheriff is at the county, but there may also be county police separate from the sheriff. In suc... |
Why isn't it unconstitutional for US currency to have the phrase "In God We Trust"? | In Buddha we Trust" or similar would be unconstitutional because it is referencing a specific religion.> Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof It's not unconstitutional for government to acknowledge religious things, just for Congress to pass laws a... |
If protons make up light waves, what makes up audio waves? | I'm gonna keep it damn simple.Light is made up of *photons* and not protons. Sound is basically vibration of particles in any medium. In air it's air molecules/particles and in solids it's the constituency atoms of the solid and such. When you speak or sound is generated, it vibrates the molecules ahead of it. Those mo... |
why are so many people christian yet get so upset when people talk about helping the poor, giving people welfare, job assistance, health care etc? | It's primarily because Christianity is as cultural as it is religious. A lot of people were born Christian without the slightest idea of what Christianity is, and try to use the majority status to their own ends. I'd say that it's a lot less about going to Heaven, and a lot more about looking good in front of others, d... |
Why is it dangerous to fall asleep after recieving a concussion? | If somebody is conscious, they can tell you how they feel. If somebody is not conscious, it might be hard to tell if they're just napping or if their brain's been banged up badly enough to force them to lose consciousness. It isn't that you shouldn't sleep, it's that anyone taking care of you has an easier time if you'... |
Why are we muscle fatiqued and cant squeeze our fist when we wake up? | There are generally two mechanisms of muscle fatigue, neural and metabolic. During neural muscle fatigue, what's really fatigued are your neurons in the brain, not the actual muscle. Neurons simply cannot keep up the frequency of signal to the muscle. Frequency encodes the power of an action, which is why the muscle wi... |
Why, in Australia, are we subsidising the mining industry? | > the metals and coal are in the ground. They HAVE to come here. Not quite that simple. If you are a mining company you want to invest in a stable nation with low costs. Political turmoil and high costs reduce profitability. We could have the highest grade deposits in the world but unless its competitive with other nat... |
why does a lunar eclipse appear red while a Cresent moon appears black when the earth blocks light? | The red is caused by the Moon being in the shadow of the Earth's atmosphere. You see the same thing at Sunrise and Sunset when the sky turns red. That red is falling on the Moon. |
The Nvidia Maxwell architecture and why the Geforce 980 is so cheap | I'm a bit confused, why are people calling the 980 cheap? Isnt it the same price point as the 580, 680, 780, when they were released? |
how do I know the gas station isn't screwing me as I'm filling up my car and the total amount I have to pay is rising on the display? | there is a flow meter inside, there are laws and agencies that make sure they are accurate. Apparently, in the US they aren't always that good: _URL_0_ The best thing you can do is learn to relate the level on your gas indicator to the liters it will pump in before the handle unlatches itself. This way you'll know if s... |
If Ferdinand Porsche had already designed the first hybrid electric vehicle in 1901, why was that hybrid technology never used until 1997? | Because the battery technology wasn't ready yet. Yes you could have an hybrid electric vehicle, but it was a really bad vehicle because the battery was heavy and not powerful. |
Why are car windshield's slanted, but bus and train windshields straight up-and-down usually? | When you've got the kind of mass a train or a bus has, a sloped windshield won't do much to help the energy it takes to achieve speed.Couldnt this be a space issue as well? If your driver can be right up to the front of the bus/windshield, It frees up a little extra square footage for passengers, also the driver has th... |
How was the first language translated when no one knew any language but their own? | two" and "three". But not only the words: we have also learned some grammar as well. We know that, for at least some nouns, the following rules apply: 1. The number comes before the noun, as it does in English.2. When talking about two things, the noun has the same form as the singular.3. When talking about three thing... |
How much authority do campus police and security guards really have? | It depends. Many colleges hire deputized officers who will have the same function as policemen, in these cases they do have the same power as policemen. In other cases they are more like security guard, they won't be able to search your person but they can remove you from the premises. If by belongings you mean your do... |
Why haven't us wealthier nations helped out third world nations enough to become 2nd world nation or even 1st world nations? | We do a lot actually, and things are changing quickly. People have this weird idea in their mind that there is only third world abject poverty and first world abject wealth, but the fact is that there is a spectrum of levels of wealth, and the bottom 3 billion people could easily be brought up to the level of the 4th b... |
Why do phones have a limit of how much expandable storage they have? | It's usually based on what's available in the market at the time and therefore what the phone is tested to work with. MicroSDXC is a standard which supports up to 2TB, so any SDXC hardware will support that. Any listed limit is either arbitrary and can be changed once the hardware is tested, or is purely down to market... |
Why do elevators have two separate call buttons? | Imagine you're on the 4th floor, and you want to go down. The left/elevator is currently on the 2nd floor, and on its way up to the 52nd floor. But you've pressed the call button so it stops for you, and carries you all the way up to the 52nd floor before bringing you back down! At best, if this is the only lift/elevat... |
Why are there no regulations on how bright headlights can be? (And if there are, why so bright?) | They're working on it! The rise of LED and HID lights made it a significantly bigger issue. One issue is that in order to see farther away you need more light, but more light blinds other drivers The IIHS has started testing headlights including glare for oncoming drivers. With a bit more data there should be recommend... |
why are solar powered desalination plants not widely used? | Desalinating water takes a lot of energy. The simple approach of boiling and condensing water is really really energy intensive, while the modern methods used are just really energy intensive. Using solar panels doesn't change this fact. Building a big solar array is not likely to be cheaper than just getting your powe... |
Given that America has one of the most powerful armies. Why don't they use that power to stomp out Mexican cartels and the gang problems in and around the USA? | Well for American Gangs you run into stuff like the black lives matter movement. You can't just start shooting people you think are gang members because you need probable cause to arrest and someone and then they would have to resist for you to shoot. Gang members are still citizens and therefore have rights. Also you ... |
How do they get that footage of forming foetuses from inside the womb? | [Do you mean images such as this?] They use ultrasonography & are a routine part of prenatal care. They work by transmitting extremely high frequency sounds from a handheld transmitter into a person's body, where they bounce off any area where there is a density change in the different tissues & are picked again by the... |
Why would paramedics actively try to resuscitate someone who's dead? | Sorry for your loss. What a terrible experience. Internet hugs to you. There have been cases where paramedics arrived and someone seemed plainly dead yet they were in fact revived. So if they're not sure, they try. They don't want to give up on someone who might eventually be ok! They just don't know for sure right awa... |
How is buying insurance not a waste of money? | Because that really isn't practical on an individual level. Imagine today that you cause an automobile accident. Between the damage to the vehicles and medical expenses, it will cost $40,000. Do you have that much saved up? What happens if you don't? Or imagine that you purchase a house for $100,000, and a year later i... |
how car insurance pricing works. I just switched companies and my price went from 201 dollars a month to 102 dollars a month for full coverage, how can such a large difference happen? | I used to work as a statistician on an auto insurance price optimization team. Aside from the fact that different companies have varying risk appetites, pricing models , some companies offer you a price which is also based on their perception of your price elasticity. If they view you as price inelastic you will typica... |
How does an spacecraft engine blast cause movement if there is nothing for the ship to push off from? Like if space is nothing, what is the engine propelling from? | The spacecraft sacrifices a part of itself to be pushed off of. There are two principle differences between space travel and conventional travel. 1.) In conventional travel, there is a medium to push off of. In a car, that's usually a road, or the Earth. In a plane, that's usually the air. In space travel there is no m... |
Why is our saliva disgusting after we spit it out, though we swallow it all day? | As soon as a fluid leaves your body it picks up foreign bacteria and other nasties you don't want back in your body. It's a natural evolutionary reaction to be repulsed by fluids that have left you. It just might keep you from getting sick. |
Why/how did taxes become so complex, how come a simple tax, like 30% of income never took root? | Basically, a set tax rate is far more punishing the less money you make. Think of it like this: Lets say I make £200,000 a year. If I'm taxed 30%, my take home pay for the year would be £140,000. If I'm on minimum wage, here in the UK, that's £13,824 a year .at 30% tax, my take home pay is only £9676.8 In both cases I'... |
Please eli5 why does it take my printer a full 5 minutes to cancel a scan when I push the cancel button? | I'd recommend getting a Brother printer. I've used Canons/Epsons/HPs my entire life and thought that printers were just universally pieces of mechanical shit, but then I got a cheapo $100 laser printer from Brother and jesus I never thought I would evangelize a printer but goddamn this thing is awesome. Prints so fast,... |
Why is there no truly reliable contraceptive for men? | Vasalgel is in the works and having very positive results in the trials. I think that until recently the demand hasn't been there. |
Why does a dead battery in a car get recharged if you just jump it and leave it running ? | There is an alternator that is driven by an engine belt that recharges the battery. The engine generates it's own electric power when it's running and what's left over charges the battery.thanks for the answers, i just never understood that, seemed illogical to me, |
Why can't I re-create something I imagined exactly? | As a film teacher this is something my middle school students and I talk about all the time - the gap between what you imagine and what you can actually make. It's not just about experience, it's about precision. You want that shot just so? Then go MAKE IT JUST SO, to the frame, to the second, and don't settle for good... |

Why Does Shutting Your Computer Off Every Once In A While, Make It Perform Better? | Programs can be thought of as very, very specific directions, which computers blindly follow. For the most part these instructions are exactly accurate, so the computer winds up where it needs to be. Sometimes, though, the directions aren't quite perfect, often because the computer is in some situation that the program... |
Queen Victoria ruled over one of the most powerful empires in history for almost a century. So why did it take until 1918 for women to be considered politically intelligent and allowed to vote? | Interestingly, I read a book about political philosophy from I believe the 1840s if I remember right, and the author brought up the subject of women voting. He said that intellectually he couldn't think of a reason why women should not vote, but that the man was head of the household and that he wouldn't want to introd... |
How can one prove the solar system is heliocentric without access to scientific equipment? | Observe the planet's orbits and note where and when they backtrack.Try different celestial bodies as a fixed point.

Why head hair continues to grow, while pubic/leg/arm/underarm hair seems to reach a limit growth? | I remember reading this exact thread somewhere before, I think on AskScience. EDIT: Found [*this*] in AskScience FAQ's.Alternatively: When I was five, I used to think that shampoo caused your head hair to grow, so I frantically avoided getting shampoo anywhere on my body, lest I spawn a forest on my backSo, just how bi... |
What causes muscles to twitch or vibrate randomly and uncontrollably? | Sometimes it's a lack of certain ions/vitamins. Neuro-somatic junctions typically require sodium for the impulse to travel, but you'll also need others for more specialized impulses.

(for my son): why does keeping food cold make it last longer? | Temperature is a measure of energy. most microorganisms work optimally in a certain temperature range if it's colder than this, the reproduction and movement is slowed down.

Why is the cost of college increasing so much in the U.S.? | Easy money/credit/loans. That's how all bubbles form. I kind of wish my student loan office would've denied me, because then we would've all been rioting in the streets, and schools would have to lower tuition due to public pressure. |

Why is the sign for a dollar $ when the dollar starts with a 'D' | As a kid I've been taught that it's not a letter S with vertical line at all. First, originally it has two vertical lines.
