The controversy of the Bali 9 case, specifically Andrew Chan and Myuran Sukumaran | Now I'm no expert, but there seems to be two main issues which make this case controversial. Firstly, the United Nations considers the death penalty to be a violation of human rights. Not only that, but if the death penalty is applied, the UN believe it should be reserved for the most serious crimes. These involve inte... |
Why do (straight) guys like tits and butts? | Men are visually oriented so their eyes are drawn to the features that are unique to the opposite sex.

Why would erasing everyone's debt be a bad thing for the economy? | One man's debt is another man's investment.

As a musician I see no reason why a musica... |
why can I move my ears? Is there an evolutionary reason behind it? | My best guess it's exactly for focusing on sounds around you. Leftover muscle from the good old times when we needed to be careful with clever dinosaurs that prowled on us. I can wiggle them independently too. When there's music, I wiggle them in the beat, along with my eyebrows and nose. I can also move my scalp! Inte... |
If the theory that the Moon is created from asteroid and Earth collision, why does the Moon reflect sunlight and the Earth doesn't? | The earth does reflect sunlight! How do you think astronauts take all those [nice pictures of earth from space]?', "The moon reflects reflects only 12% of the light that hits it, this is pretty low and is the same level as worn asphalt You see the moon as reflecting a lot of light because its getting blasted by the sup... |
How come there are no apes/monkeys on the north american continent (northern Mexico, USA(Merica), Canada)? | I'm assuming you mean other than Bigfoot. It's theorized that there were monkeys and/or apes in North America at one point. There are fossils found in Texas of primates dating back 43 million years. Scientists believe that primates crossed the Atlantic on vegetation rafts, a common practice for crossing short distances... |
When in a swimming pool or body of water what causes the high pitch sound to occur when our ears/throat are close to the surface of water? | On a surface of water there are little to no obstructions meaning sound can travel further without interruption. Certain sounds like echoes also travel further and also merge with other noises which can come across as eerie pitches when combined. So what you're hearing and parts of sound waves combined together all at ... |
Why do people 'reach for the sky' when they get knocked out? | It is called the "fencing response" and from what I can tell just has to do with the arrangement of the lateral vestibular nucleus and that injury to the head will stretch the cerebellar peduncles and activate the LVN. Basically, hitting your head whacks motor nerves that make you take a fencing stance. |
Where do the children of the POTUS go to school? | The Clinton and Obama kids went to Sidwell Friends school in DC. Which is a private school.

why does coffee seem to taste so much better first thing in the morning than during any other time of the day? | I've never really noticed that, it always tastes the same for me. Might be because you have some remaining chemicals on your taste buds which affects the flavour, but not 100% sure. |
Why hasn't the RJ45 port (Ethernet) changed much over time? | I think it helps that the use case hasn't shifted too much. USB has been forces to change form factor by mobile devices as they shrink. Ethernet has been replaced by wifi for small devices. Early TV/display cables were analogue so were constantly chnaged to meet requirements. HDMI might be here to stay as it's a proper... |
If heat rises, then why does it get colder as you get higher on mountains? | Because air expands as it reaches areas of less pressure , and expanding air cools down. Changes in heat with pressure are exactly how air conditioners, fridges, etc work. They compress "air" so it gets hot, dump the heat outside where it isn't wanted, then let it expand and therefore cool, next to the area where you w... |
Why are smartphones getting thinner and thinner? | The market has said that all else held equal, they want thinner phones over doubled battery life. Every phone has to have some sales niche.

Maybe two to be sure ? Is it much ... |
Emulation and why it takes more power than native applications. | Think of it like your computer's acting a role instead of being itself. If I had you act like Winston Churchill in every interaction in your life, you'd have to slow down and think before you speak as well . In more technical terms, when it's running an emulator, your computer is running a program that *runs programs*.... |
When my leg falls asleep, why does it feel like I'm being electrocuted by the wrath of Zeus? | your nerves are essentially disconnected from your brain, that is them "reconnecting"', "When your leg has had pressure applied to it for a long time , the nerves essentially turn off.

If life started in salt water oceans, how do lakes all over the world have fish? | > How did they get there, and where did they come from? Birds carry them, or their eggs. > Why would something become a land mammal only to somehow become a fish again? What, like whales and dolphins? Where did mammals come into it? Freshwater fish came from saltwater-fish ancestors. > Saltwater fish can't live in fres... |
What are CASE tools in programming and how are they used | CASE, Wow! Haven't heard that in a while Computer Aided Software Engineering. Back in the days when software was rarely properly designed, when it was, it was usually with a pen and paper on a spare piece of paper. Then someone came along and said, 'Let's use software to design our software!' and so we started using st... |
What are the chances of an asteroid impact within my lifetime, and the chances of one being deflected? | The chance of a severe asteroid impact occurring in your lifetime is incredibly small. Very, very, very few cataclysmic-level asteroids have impacted earth in the past. The chances of a smaller, city-destroying asteroid impact are much higher , but still extremely unlikely to happen in your lifetime. The smallest meteo... |
why do websites need "mobile versions" of websites? Dont they work the same way? | There are three types of mobile versions of websites, mobile apps, media queries, and mobile websites.

Malleability vs. Ductility in metals | Malleability refers to how much a material squishes out to the sides when you squeeze or hammer it. Ductility refers to how much a material can be stretched without breaking by pulling on it. They're both related to how easily particles slide over each other, but the directions involved can be a deciding factor. Also, ... |
Why is it so common for my power to briefly turn off during the first thunder of a storm but then be okay during the rest of the storm? | * Because the ratio of C-G vs C-C lightning changes. * Depending upon cloud height above ground and changes in electric field strength between cloud and Earth, the discharge stays within the cloud or makes direct contact with the Earth. * So when a storm approaches there may be more CG lightning which causes power outa... |
Why does my toilet make that half flushing noise randomly. What is the cause and purpose? | Check the flapper. If it is loose or damaged it may be letting water dribble out of the tank very slowly. Sooner or later that will trigger the tank to top off. |
If a public company is owned by the shareholders, and a single shareholder owns more than 50 percent of the total stock, does that mean that a single person can control the company? | That's not quite how buying shares work. There aren't infinite numbers of shares in each company - there are a set number. If a company has 100 shares, you can only buy 100 shares, not any more. But if you bought 51 of the 100 shares, you would almost completely control the company. You could make decisions, appoint th... |
What keeps people who work at KFC/Coca-Cola from stealing a sample of their secret recipes, reverse engineering them, and then selling them? | Not a huge amount, really. We already pretty much know what's in these products . The difficulty is only getting the exact formulation and mixing right. For most people, the prohibitive part of that is not knowing how it's done - it's having access to the kind of production chain that can produce that product consisten... |
Why is the American pres campaign season 1.5 years long, while in other developed countries like the UK and Germany election season for the PM/Chancellor is only a couple of months? | In parliamentary systems, it is a given that the representative of the largest party will become prime minister. What's more, even if you don't like your party leader, you usually can't do anything about it--if you are a conservative voter in the UK, support for your party necessarily means support for David Cameron. M... |
If someone has, say, $20,000 in the bank and they get sentenced to life in prison, what happens to the money? | It's not like being sentenced to life in prison means you're legally dead. The prisoner could just give/transfer the funds to whomever he chose. Or, they'll keep it for themselves in order to pay lawyers for appeals and the hope of someday getting parole. |
Why can't doctors simply take a blood test to check for all cancers? | Because they dont all show up in blood tests its that simple. Some cancers produce chemicals that can be measured in the blood called tumour markers. But not all. Also you can have a full blood count test to measure the level of these cells to see if you have cancer of the blood or ~~bobe~~ bone marrow: 1. Red blood ce... |
Why are there ads on cable TV if I'm paying for it? | To make it cheaper. Simply put we don't pay anywhere near enough to pay for the shows we watch", 'Money. The networks know that you want the content bad enough to sit though some commercials. |
Exactly what happens when my "heart drops" | When you experience duress, your body enters "fight-or-flight mode". You excrete a hormone called epinephrine that increases your heart rate and your direct blood flow to the arms and legs . The feeling of your heart dropping is the sensation of having a higher volume of blood in your extremities compared to your core ... |
Why do radio hosts have to periodically stop whatever they're doing to give a "station identification?" | the FCC requires US radio stations to do "station identification" at the top of each hour, or as close to as practical while not interrupting programming in the case of NPR, it may be more of a branding thing, since the show is syndicated and NPR itself isn't the broadcaster, but the local radio station is _URL_0_This ... |
How are rival companies allowed to slander each other in their commercials? | Usually they say very vague things like "unlike our competitors" or "unlike the leading brand" instead of naming a competitor outright.

Why do people on Reddit feel the need to announce when they edit their posts/comments? | It is a type of etiquette that helps to prove your honesty. It came about from people who edited comments, but then the responses didn't make sense. So the tradition that has built up to belay confusion is to announce edits. It is now a sort of pride thing. |
Why is "Latent Tuberculosis" not contagious? | Just a couple of basic facts to lay out; Tuberculosis is a disease caused by a bacteria and this particular bacteria is one that naturally lives *inside* cells. This is in comparison to a bacteria like E Coli that forms colonies outside of cells. This is important because for something to be 'contagious' there needs to... |
How does a computer or phone keep time even when it's turned off? | Computers have a tiny battery, the so-called bios battery for exactly that. It also keeps the bios alive. |
How come blood comes out of a person's mouth when stabbed or shot in the chest/stomach? | This would happen if the wound punctures a lung, the stomach, or esophagus, because all those things have fairly direct connections to the mouth. It would be easy to believe with a lung hit especially because the blood would be forced up by coughing. I imagine it's more frequent in movies because it's a striking visual... |
Dialysis and How It Works | The blood runs over a membrane which has holes small enough to allow the bad stuff to filter out but the good stuff to stay . On the other side of the membrane is essentially water and salts in the ideal concentration for the body. The bad stuff flows from a higher concentration in the blood to the lower concentration ... |
How do viruses propagate between computers? | As a concrete example, a PDF is an executed file. There's actual code in a PDF that needs to be run, unlike a text file where it's simply read and displayed. This means that when you open the PDF, the attached code could very well run, and if that code is malicious, then there goes your computer. Additionally things li... |
How come Jupiter's spot lasts so long? | It was first observed over 350 years ago, so it has persisted at least that long. Modeling atmospheres is ridiculously difficult though, so we really have no idea when it actually began or when it's going to end. I don't really know much about the physics of the planet, but Jupiter definitely has tremendous winds, temp... |
why does chewing gum help prevent ears from popping when flying? | 2 reasons: There is a tube that runs from the sinus cavities to the ear canal called the eustatian tube, and it equalizes pressure. So.. 1. Chewing gum helps move the jaw in a way that it opens this tube more. 2. Chewing gum increases saliva, which causes you to swallow more. Swallowing also helps open this tube. |
Why do some people's personalities completely change when they are drunk? | Alcohol basically has an anti anxiety effect. A person's level of anxiety is a huge part of their personality. Some people are extra nice because they feel if they are even a bit rude, people would stop talking to them. Now, when one gets drunk, this filter disappears, and they lose the need to try to impress people an... |
Why can't we take an even root of a negative number? | Because there is no real number that, when multiplied by itself, results is a negative number. A positive number multiplied by itself is always a positive number. A negative number multiplied by itself is also always a positive number. Because mathematicians are a pragmatic bunch, they have devised a way to work around... |

Why the US dollar has been subject to 768% inflation in fifty years ? | Because inflation is good. Sort of. 700% sounds like a lot, but actually it's only about 4% each year. And that's not a lot.

What is a topological space? | This question is kind of hard to answer without knowing your level of involvement in math. Could you shortly sum up what you know about set theory?To get a little bit of intuition for some topological properties, remember things you learned about continuous functions in calculus. Continuous functions are exactly those ... |
How can America be split so evenly between Republicans and Democrats? | It's because the parties themselves are changing, every year, to ensure that they don't get left behind. As people who are moderate start to lean Democrat because of X issue or Y policy and the Democrats win an election, the Republican party starts to change its stance on those issues, swaying back some voters. Same th... |
what's the difference between quick nap dreaming, to dreaming we have in REM sleep? | REM sleep dreaming is much more in-depth, because it comes from your subconscious. Those are dreams that last up to a few hours at a time, but we rarely remember in the morning. Light sleep dreaming will come from your brain trying to make sense of its immediate environment, because it hasn't gone into sleep mode yet. ... |
What does the IMF actually do? | The IMF is there to make sure countries have enough money. So when a country signs a trade agreement , the terms of the trade are usually denominated in a more developed countries currency .

How did humans get to North America if life started in Africa and there were no boats back then? | They walked. You can ask from Africa into India, Asia and Europe. Back then there was a land bridge between Europe and North America at the Bering Straits. They walked over that and walked south. More interesting in the migration of humans to Australia 40K years ago. Also the migration from the southern China coast of ... |
When traveling, why does the trip back home always feel so much shorter? | Because the brain stores more information during periods of novelty and newness which stretches your perception of time. It's also why you store more memories on vacation than you do in your regular boring daily grind. |
why do humans feel depressed over lost relationships for years after they end | That is a bit biased as not everyone does. But we are a social species who have evolved to survive together and a good way to do that is to encourage individuals to seek out friends/lovers whatever you mean and to hang out with them. IT increases your chance of survival since we humans cant really survive alone in the ... |
What does it mean to refinance a house? | Most people take out a loan to buy a house and they use the house as collateral for the loan. This means that if you don't pay the loan, the bank can take the house and sell it to get its money back. These loans are called mortgages. They have certain terms, such as the interest rates and over how many years the loan h... |
Why hasn't here been a new Age Of Empires game after AOE III? | Ensemble Studios, the makers of the Age of Empires games, was shut down in 2009 after completing Halo Wars. Probably because of under performing sales and around that time, the RTS genre wasn't that popular, as opposed to the FPS games. Microsoft was probably more interested in the Xbox as well during that period and w... |
Why did my flight not have a row 11? | I've looked up the AA seating charts, and two of the Boeing 757 designs don't have a row 11, but they also are missing other rows: _URL_1_ This one is missing 6,7,8, and 11. 6-8 are missing due to the galley/bathroom, and 11 is missing because 9-10 are offset due to the exit row. _URL_0_ This one is missing 5-8 for the... |
Hypothetically, if we were to wipe out every human being who currently has aids and every animal who has aids, will there be no more aids in the world ever again? | With AIDS specifically, yes . That is assuming no lab samples survived. This would require destroying many species of primate though, as many populations carry a very close virus without ill effect. So if they were still around, it could always jump species againOut of a technicality, no, because AIDS is the syndrome, ... |
How does air move into the lungs? | Your diaphragm is a muscle in your body that causes your lungs to expand or contract. When your lungs expand, their volume increases. When their volume increases. the pressure in your lungs drops, and in fact, drops slightly below the pressure of the air surrounding you. The pressure in your lungs is now lower than the... |
Why unplugging and re-plugging fixes a modem/wireless router that has stopped connecting to the internet. | It's called [power cycling.] The longer a program runs the more likely it will be to run into an error and crash or hang. Power cycling works because it starts whatever software is inside the machine at its initial working state. It works so well and is so easy that this is the first thing that any tech support person ... |
Why do people from South Asia clean their bum with their hands instead of TP? | They might ask why westerners simply wipe their butts with paper. If i smeared excrement on your arm, would you be satisfied just wiping it off with some paper? Additionally, in my experience in Thailand, Lao, Cambodia and Vietnam they used a handheld sprayer in combination with toilet paper. Though i do not doubt that... |
Historical use of "modern" and "post modern"? | I can't answer your whole question, and there's inevitably going to be personal opinion here. "Post" means "after", but in this context it also means "in response to". So "post-modern" is a reaction to "modern", stemming from dissatisfaction with the state of "modernity". The reaction isn't always strictly negative , i... |
why is it so hard to realize that you're dreaming when you're dreaming? | I watched a PBS documentary a while back that theorized that dreams are 'training programs' that our minds create to prepare us for significant situations; albeit, not always very well. That may or may not be true, but if it is, it wouldn't make sense for us to know we were 'training' because that would negate the imag... |
The Complicated Time Travel Question | Seeing as time travel is impossible, all rules as to how it works are imaginary. You might as well ask what would happen if a dragon get stung by a bee. What happens is whatever you want to happen. |
how does a numbing agent block pain but not pressure? | Because the nerves responsible for pain are different than the ones that feels pressure. A numbing agent basically makes it so that the nerves responsible for sensing pain don’t fire any messages. But you’re nerves that sense pressure work differently so the numbing agent doesn’t work on itThere are more or less five d... |
Why does the way one person drives affect passengers with sickness but not themselves? | One of the causes of motion sickness is that your brain isn't able to match up experiences from different senses. If you're driving, you know when you're turning, braking, speeding up, etc, so your brain has already decided it's doing something and is carrying out that maneuver. If you're a passenger, you don't have th... |
Why doesn't Reddit ban overtly racist subreddits dedicated to hate speech or the pedo subreddits? | I think one of the basic principles behind reddit is the minimal level of admin involvement. The idea that you can make a sub for damn near anything is the whole point. Blatant, trollish racist posts tend to get downvoted into oblivion in normal subs. People with a history of posting on them will have even somewhat inn... |
Why does it take pressure AND time to make diamonds or other crystals instead of just pressure? | Oh contraire. Doesn't necessarily take time, you can substitute time for heat and that's how you can synthetic diamonds.The easy answer is that coal has several states it can be in, diamond is the state that takes the least amount of space. So whenever carbon atoms start to bond in a diamond structure some pressure is ... |
If symptoms of a cold serve the function of ridding our body of the illness, then do cold medicines that reduce these symptoms slow our recovery? | Yes. This has been proven in animal models and strongly suggested by human studies . From the Business Insider article [Your Cold Medicine Could Be Making Things Worse]: > In one study of people with the common cold, researchers found that those who took fever reducers shed more of the virus than people who didn't. And... |
Why does every product that is made in china must be labeled as so? | Country of origin labelling applies to anything imported into the US. Check your clothing tags for example. These labels are required by the FTC for the US, and serve for consumer information and trade reason. It can be both a positive or negative labelling. For manufactured goods, made in China is usually frowned upon... |
how the fed reserve works | As you may be aware, the Federal Reserve is the central bank of the United States. This means that they control the monetary policy of the US, which is a fancy way of saying that they control how much money is in circulation . It does this in three ways: - **Open Market Operations**: This consists of the Fed buying and... |
If I could measure my 3 year old's brain chemistry and then adjust mine using some future technology to match hers precisely, would I have her same amount of (seemingly endless) energy? | Well, this is a pretty sophisticated question, but one issue that is important is dopamine receptors in the brain. Dopamine contributes towards energy and enthusiasm, and we lose like 11% of our dopamine receptors per decade of life. Take this with a grain of salt, I'm not a scientist. But with fewer dopamine receptors... |
How does bail work? Do you just pay to get out of prison and that's it? | It gets you out of JAIL which is where you would otherwise stay leading up to and during your trial. It does not get you put of PRISON which is where you go if you are convicted and sentenced. You dont pay to get out of your crime. You pay to stay free until your verdict is reached in your trial. You get the money back... |
Why do we get "butterflies" when we like someone? | Adrenaline. When you meet someone you are ridiculously attracted to, your whole body is affected. One of the most prominent ones is the release of adrenaline that boosts your bodies metabolism and energy levels in preparation for sex. Because biology hasn't exactly evolved to take into account for current world courtin... |
Why did soldiers in the 1800s put their ears to the ground to hear enemies approaching | Because the shockwaves of the boots and wheels of approaching enemies travel further through the ground that the audible sound does through the air. Edit: The Wabes have been eradicated!The Indians used to lay their ear on the traintrack to hear if a train was comming so they could ambush them.I think the better questi... |
Why does it hurt more when we put salt or pepper on a wound? | One quick round of google-fu brings me to this: The reason that salt stings a cut is that as the salt dissolves, it causes the fluid surrounding damaged tissues to become extremely hypertonic . Pain-sensing neurons have receptors on them that respond to a variety of stimuli. For example, there is a specific receptor th... |
How is it possible that someone can be rationally thinking about why they should not be scared/nervous, but still feel it in their body? | It stems from the fact that our emotions are much more core to our being. They are autonomous responses that have been present in our evolutionary history for much much longer than conscious thought - hence why they are at the centre of our brain. The human brain is constructed much like an onion, with older evolutiona... |
Why is it hard to read books, but easy to surf the web for hours? | A constant term that pops around about why the internet is so entertaining is “instant feedback” or “instant gratification”, something among those lines. Essentially, browsing the internet and going on Facebook or Twitter gives immediate feedback and reward to small actions like simply clicking on an article or loading... |
how do huge transactions take place? | Wire transfer, and its not a big deal You have to understand that financial institutions transfer and mash around billions of dollars a day, and in far more complex methods and such, none of this is an issue. This is just one more transaction taking place between computers talking to each other. |
Are all quartz watches built the same? | An expensive watch movement will have higher tolerances. So things like the gears inside it will be a higher quality and thus less likely to degrade and "loosen" up. The quartz crystal itself and the basics of how it works are the same, AFAIK, but higher quality materials means it will last longer and continue to be ac... |
The difference between watt, joules, and amps. | These are units for different things. Amps are a unit of current which is the rate at which charge flows. Joules are a unit of work or energy. Watts are a unit of power which is the rate at which energy is generated or consumed.Take the example of a space heater that has 2000W or 2kW. This determines how much heat it g... |
[LI5] Why don't we have one universal language? | It's difficult to work toward for a couple reason. 1.) It would require alot of people to learn different languages that they would not use in their daily life. For example in Afghanistan it is not uncommon for people to be illiterate and speak 3 different languages, none of which are English. 2.) Languages change base... |
Why is butt slapping so prevalent in major league baseball? | I think it's just an appreciative gesture. You know, I guess you get bored in the dug out too much with men. Not only baseball do it, American "football", bball as well |
how can I throw a water bottle and drop a water bottle at identical heights and they both reach the ground at the same time? | They won't always hit the ground at the same time, but so long as you are throwing it neither towards or away from the ground, they will. This is because velocity and acceleration have direction. When you throw it, you are giving it velocity in the horizontal direction, but none in the vertical direction. Because the g... |
SQL Injection Attacks and DDoS Attacks. | What likely happened with your university is someone gained access to an administrator's password. Most of these "hacks" aren't as sophisticated as the hackers would like you to believe, and generally involve social engineering to gain access to the password as opposed to some hollywood-esque technical maneuvering. |
The relationship between an IP address, Network address, Broadcast address, and ports. | Network and Broadcast addresses are just specific predefined IP addresses, so I don't think it's necessary to try to think of them any differently.

Why are some car brands (like Toyota, Honda, etc.) so reliable, while other brands are not? | AFAIK, Japanese manufacturers made their cars very reliable in order to cut down on costs of spare parts shipping to other parts of the world. They achieved that through, as it's mentioned before, rigirous quality control, and it payed off. They were also a bit more expensive due to shipping and quality control. Once t... |
How do fish survive tall waterfalls? | Couple things contribute. Fish are fairly small so they don't gather much kinetic energy. They're also shaped much more streamlined than most animals so they enter water much more smoothly and gracefully.

Why aren't there big social movements anymore in the US, e.g., temperance, religious reformation, segregation, etc.? | I suspect that it is easier to see the magnitude of a movement in history books, in which a great deal of irrelevant information is cleared away, rather than in the present, when it is simply part of a large, complicated world which no historian has yet sifted through, seeking the histories of those ideals which have a... |

how a defense lawyer is able to change a speeding ticket into a non moving violation so that I don't get points on my record | Criminal courts, especially for minor crimes and infractions, are super busy, and extremely backed up.

How did humans start measuring angles and how do we know for sure they are even relatively accurate? | The Babylonians in 1500 BCE measured angles using a hexagon, dividing a circle into 60*6=360 parts and using pi = 3.125. Before that, the Egyptians had a gadget called a groma that measured right angles. They were accurate enough to build the PyramidsWe have been measuring angles for nearly 6000 years, they go back abo... |
How are ISPs like comcast not illegal monopolys? | Laws must be established that certain companies are "common carriers" and follow rules. These are special laws written in legislative bodies. Some examples of these are bus lines, pipelines, railroads and other companies governed by laws. But for this to happen special laws must be passed. |
How did we come to know that it takes 365 days to make a complete revolution around the sun? | By measuring shadows. Imagine you put a stick in the ground, and marked the tip of shadow's location at the same time every day for a year.
