Why do you get that awful feeling in your stomach when you hear bad news or feel betrayed or jealous? | Your intestines are lined with nerves, to the point they're practically a second brain. Sometimes they react to feelings, like when you're having butterflies in your stomach. |
How do cable companies and streaming services protect their content from being hacked? | If you're talking about how they protect their content from being *copied*, the simple answer is that they really don't. If you plan on rendering video on an end-user device, the only way to prevent it from being copied is to have complete control over the hardware on that device. Otherwise, the end-user can simply rip... |
When censoring people’s identity, why are only the eyes covered? | This is most common in still photos, I think because people focus on the eyes. You are right that it is not the best identity hiding method, but just provides some privacy. TransGirlInCharge listed some methods often used in video. Like her I've seen videos where you could tell a lot about someone's features. About 20 ... |
Why do you have to occasionally restart your computer after installing a program? | Some programs that run in the background need to be run before others, because they rely on one another. But these programs are already running, so when you reboot, it gets to run the new programs first. If you bought a new pair of underwear, but already had pants on, you'd need to take your pants off first before putt... |
Why are most smartphone touchscreens made out of glass instead of plastic? | It's a trade off - glass is much easier to break but is also much more scratch resistant. If you had a plastic screen, it would be covered in micro-scratches very quickly from the normal abuse that a phone takes. Dropping your phone and having the glass break does happen, but at nowhere near the regularity as the scrat... |
Why hasn't anyone landed on the moon again? | For the U.S, the early space program was largely about competition. Sparked by the Soviet Union's launching of Sputnik 1 into low earth orbit, the space race was pretty much just an extension of the Cold War. After the United States achieved the first moon landing , public interest began to decline. By 1972, only three... |
why would PC beat a console in cross platform gaming? | * Precision - Computer mice precision is measured in dpi which means how many unique positions can be measured while moving it one inch in a direction.

if the majority of people are right handed, why does the fork go on the left when setting a table? | The fork is held in the left hand when you're cutting with the knife. You cut with your right hand for a couple of reasons: 1. if you're righty, then you'd embarrass the hell out of yourself when cutting with the knife using your left hand. 2. someone long ago thought we ought create social rules to help people from em... |
Why does the US have five branches of military? | Well, historically, separate branches of military can be specialized. Generals don't need to know how to sail a ship, admirals don't need to know how to form troops in a fighting line, etc. This theoretically enables them to become specialized in their particular form of warfare. US Marines were originally designed to ... |
how do figure skaters not become dizzy when their routines consist of so many spins? | One of the techniques you will see persons use is to hold their head still through most of the spin. The fix their attention on one spot, holding their head still, twisting their neck as their body turns. Then they will 'snap' their head around quickly, focusing again at the same spot.You get dizzy because you try to f... |
How did humans become so intelligent. While other animals didn't? | sexual selection creates exponential change whereas natural selection creates change until an equilibrium point. there's evidence to suggest that our brains formed from sexual selection which then got all out of proportion until our brains were doing amazing things. |
How does gas rise if the gravity of the earth pulls everything towards its center? | Buoyancy. Gasses rise because they are in a fluid, air, and are less dense than it. That means the weight of the air they displace is greater than the weight of the gas itself so the air sinks instead of the gas. It's the same reason a stone sinks in water.Because it is lighter than the surrounding air. Same reason Sty... |
What is happening in the body when a person is depressed? | I have depression and have done a lot of research, but it's still hard to understand. Basically what they think happens is that the neurotransmitters get blocked, so the messages can't get through. Or they don't have enough power, or something. At any rate, that's what the meds are supposed to do, boost the signals of ... |
How does the gas meter on a car work, and why does it only work when the engine is on? | The\xa0sending unit\xa0is located in the\xa0fuel tank\xa0of the\xa0car. It consists of a\xa0float, usually made of foam, connected to a thin,\xa0metal rod. The end of the rod is mounted to a variable resistor. A\xa0resisror\xa0is an electrical device that resists the flow of\xa0electricity. The more resistance there is... |
The "Pause/Break"-button next to the "PrintScreen"-button on your keyboard. Every PC keybard has one, why doesn't it ever function? | Age of Empires used to use it to pause the game, which seems like a pretty sensible thing to do. I expect the reason it's not used more often that is because nobody ever thinks about it, which is because it's never in anyone's mind, which is because it's not used more often. |
why do we see lights as on? | > Why do our eyes get drawn to the light ON state? Because half of something is not zero. If an LED is on half the time we see it at half brightness. You don't see it in the full on state or the full off state. It could be dimmed to the same level without switching, but switching on/off rapidly is often more efficient. |
When listening to music, why do i know all lyrics in my head but when i try to start singing i dont even know one word? | A lot of it has to do with the kind of connections your brain makes when memorizing things like lyrics. When you hear the rhythm/other instruments, it opens up parts connections that you couldn't have reached otherwise . Certain memories need to be triggered until they are more engrained, which is why hearing the song ... |
Why and when did sex turned into a dirty sin and become something bad or something we can't open talk about? | I wish I knew ! I know it's definitely a cultural thing. My tribe is super chill about sex, but like when white folks forced Christianity on us it did change how we view sex to some degree. My family follows the tribal tradition so we are still very liberal about our sexual views, but Christians in our community tend t... |
Why do online job applications ask you to submit a resume, but then make you type it out manually? | If they have you fill in a form, it allows them to standardize the printouts or reports that they look at. It's much faster to review dozens or hundreds of applications if they are all in the same format. Resumes are not. |
How do authors remember a lot of specific details from events or conversations they've had when writing autobiographical works? | It's a trained skill. [You can learn to do it too]. It just takes practice and desire to learn. If you're a fan of Sherlock, you can even train yourself to use a memory palace to really store stuff. But mostly, it's just remembering the story and why certain facts are relevant. The more you can tie different memories t... |
Why is it often repeated that if the human species were to disappear our footprint would disappear in a relatively short time period, but bones buried in mud last hundreds of millions of years? | Our footprint wouldn't actually disappear. If our species ever dies out, it's true that after some tens of thousands of years, you might not be able to tell we were here with a casual glance. But as soon as some future civilization started practicing anything like modern archeology, they'd find signs of us everywhere. ... |
Airsoft: what are these guns for? | My son's friend has a fully automatic airsoft rifle. He said it cost around $1000. Yeah, he was seriously into it.Yes, people do play airsoft like they play paint ball. I believe the style of play is slightly different.It's a similar idea to paintball. There are usually teams and you shoot eachother to eliminate the ot... |
Why do the refugees prefer coming to EU countries by train or even boats when it would be cheaper by plane? | Airlines are very strict on who they let on board. If you don't have a passport and a visa for the country you are going to, then you won't get on the flight. Most who come by sea travel on unseaworthy boats which are only intended to make a one way trip. Often they only have enough fuel to get as far as another countr... |
What is an easy way to understand higher dimensions? | The way I understand it is imagine a line on a piece of paper and a stick figure on that paper as well. The line goes infinitely making it so that stick figure can't cross, but we add another dimension and the stick figure can use that third dimension to go over that line. Imagine the same thing but in our world. There... |
Why isn't same-sex marriage legal in all states of the U.S. if all men are created equal and have equal rights. Isn't marriage a right? | That is the essence of the debate. Someone against same sex marriage will either say that marriage isn't a right, but a privileged status granted by the state, or they will say that everyone has a right to marry someone of the opposite sex, but no one has the right to marry someone of the same sex. Under both arguments... |
why the US going from AA+ to AAA is such a big freakin' deal. I honestly don't get it. | It's *not* a big freaking deal. It's one agency, with their own agenda, telling the rest of the world what they think of US debt. These are the same people who labeled Bear Stearns, Lehman Brothers, etc. as low-risk in the weeks before they defaulted. But people have typical knee jerk reactions and the stock market goe... |
What part of an explosion actually hurts you? | Imagine stomping on a bag of jelly. That's a pressure wave hitting your body.Shockwave and flying pieces of debris that can cut you.The two important waves are the detonation and the deflagration waves. Detonation waves are violently fast, and cause a rapid breaking up of matter. Deflagrations waves are slow waves most... |
How do you pay taxes in the US? If I owe $5000, for example, would I need to have a $5000 check ready on tax day? | I want to clear up some unclear explanations. **FOR WAGE-EARNING OR SALARIED EMPLOYEES:** When you begin work, you fill out an IRS form W-4. This gives your employer a rough idea of how much tax you will owe . Working from the W4 your employer calculates tax due from your gross pay and withholds it from your paycheck. ... |
how do we capture helium and put it into tanks? | > This probably seems like a very basic question but how was it discovered and how is it harnessed for everyday use? It was first discovered by looking at the spectra of the sun. Later on it was discovered to exist within natural gas deposits, having seeped up from radioactive rocks below. > Wouldn't it just float away... |
The Sony leak: How did hackers manage to transfer 100TB of data out of Sony without being noticed? | It's very equally likely that they noticed and either A) couldn't respond quickly enough, B) couldn't respond correctly, or C) didn't know where/how they were being hacked and couldn't respond at all. |
The difference between petrol and diesel? | Basically, they're each made up of different types of hydrocarbon molecules. Crude oil contains many different hydrocarbon molecules, which like the name suggests, are molecules that contain carbon and hydrogen. The smallest one is CH4 , known as Methane. Methane and the next three hydrocarbons -- Ethane, Propane, and ... |
Do people actually have "bad circulation" when their extremities are susceptible to being cold or is there another explanation? | It's common in diabetics. This is part of why extremity injuries take so long to heal in diabetics. Look up peripheral vascular disease and peripheral neuropathy. The temperature of a limb being warm to the touch when compared to the other can be an exam finding consistent with a deep vein thrombosis. Edit: dvt limbs a... |
2,013 years ago someone decided it would be a good idea to start keeping time... Who and why? | What Amarkov said. Also, it's not like people weren't keeping time before that, or that they weren't keeping time elsewhere using different schemes. |
Would legalizing prostitution/pornography lower sex crimes such as rape? | [Here's a study that suggest porn prevents rape.] [Here's another one.] [Here's a study that argues the opposite.] There's not any good way to find this out though. From what I can gather, they've noticed that the rates of rape fell with the rise of the internet, and other crime didn't change with it. The idea that acc... |
How does ring re-sizing work? How is it possible to do it without breaking or warping the metal? | It depends on what the ring is made of and the aesthetic. Lot's of traditional jewelry metals are malleable, they can be reformed with relatively little force so gold 10+ rings can be stretched. But, frequently they are cut and reshaped. |
If the fitness-test of the police is so hard, why are so many policemen so 'fluffy'? | You are thinking of this the wrong way, as if we get to set standards based on what a good candidate for the job should be able to do. In actuality we set the standards such that an adequate number of applicants for jobs can end up filling our open positions. This is effected by supply and demand. E.g. In my field, edu... |
Why are there crackers in every military MRE? | It's based on poor science. It makes up the carb allotment that poor nutritional science says we need. Our Government is slow to change, science has passed them by many times, as it has on this, the poor jarheads will continue to be abused until they catch up. |
Explain the American election system to me. What is the point of primaries, and why do we vote for individual presedential candidates if the President is decided based on electoral votes??? | In the electoral college each state is given a number of votes . The candidate with the majority vote gets all that states electoral votes. This system was set up in a time in which individual voters didn't have access to enough information to make informed decisions about the candidates, and it was difficult to ensure... |

How exactly do asthma inhalers (ventolin) make breathing easier for asthmatic patients? | They reduce the effect of Bronchospasms. Basically, the lungs are a series of tubes shaped like the upside down trunk of a tree. Where the leaves should be are tiny sacks.

why do we not get electrocuted when touching the metal end of a phone charger? | voltage is the measurement of the ability of the flow electricity to overcome resistance, its why you can put a nine volt battery on your tongue and it's just tingly - 9 volts isn't enough to overcome the resistance of your body but it has enough current to stop your heart, easily. 120 volts, like from a wall outlet, c... |
Why, when turning on electric fans, is the first setting/option always the highest setting? | Just checked the fan next to me. It's the exact opposite, with the lowest speed being the first setting and the highest speed being the third. I'm guessing it's just a design choice. |
What would happen if a newborn is raised by someone who can't talk, and that kid grows up never hearing anyone talk? | Okay, there are two different options here, depending on what scenario you are envisioning. Scenario one: we have someone who cannot talk, but can communicate and interacts with the child using this language. Think people who communicate via sign language. In this scenario, the child brain would be stimulated and would... |
What is the best/quickest way to dry clothes, according to science? | When clothes dry, it's because the water in the clothes evaporates into the air. There are three factors that influence evaporation: * ambient temperature: water evaporates faster in warmer temperatures. Being in a warm room, or in direct sunlight, will speed up the drying process. * humidity: the more water vapour alr... |
Why do hostages of ISIS seem so cooprative if they know they're going to die? | In addition to all the mind games and other unknown factors mentioned: you see the footage they let you see. It's possible that there are escape attempts all the time during executions, but ISIS has spent quite a bit of time on their footage. They kill thousands more than you see or hear about.Frequent fake , or practi... |
What's it like for astronauts who have been in space to be back on Earth with gravity? | I know they lose bone mass of .5-1% per month they are there. But I want to know if they are like dropping things and such, forgetting they don't float on Earth. _URL_0_ |
LLC vs S Corp VS "Forget it, I'm doin just fine". | > I have literally zero liability I really doubt that. If a defect in a product or service you deliver can cause someone else to lose money, you have liability. If confidential information your customers share with you can fall into the wrong hands, you have liability. And even if you don't have liability, that doesn't... |
If there was very little to no surface tension in water, would it still hurt if you were to belly flop on it? | Water is heavy. A force is needed to push it out of the way. Your belly will provide that force, and it's gonna hurt. |
How exactly does the health care system work in the United Kingdom and how does it differ from then United States? | At a very basic level, we pay income tax and a lot of that money is used to fund hospitals, pay the wages of doctors and nurses, pay for operations and medicines, ambulances, therapists, home carers etc. This is the NHS, the National Health Service. It extends to opticians and dentists too as well as training nurses an... |
Why do I have to get an undergrad degree to go to law school ? | Because its competitive, so law schools can demand that applicants have completed another degree already. It's also got usefulness, in that lots of people drop out of law school or aren't successful or good at it after graduating. Another degree gives a fallback for those students. |
Why is Ireland going to legalize heroin and cocaine? | With possession being a felony, getting treatment for heroin addiction is nigh impossible. You can't even go into a hospital without getting in serious shit. Heroin addiction is a serious illness and some people have no interest in continuing.* the cost of unsuccessfully banning these drugs exceeds the damage they do t... |
How did FB's drop in stock price actually affect the company? | It did't affect FB. It affected the investors who purchased the stock on opening day and now have lost value in those shares. The market is saying FB may be overvalued and there are concerns about their future revenue. |
What is it like to have your period in space? | It's no different from having it here on earth. There's no scientific data to show anything unusual. However there was an experiment where a rat was used, but the results showed no unusual activities. TLDRYes, they have period, it's the same, it's not affected by microgravity and it doesn't flow upwards as thought by h... |
Why, when jumping out from a moving object (ex: train) on a non-moving object (ex: ground) we fall, instead of landing stable on our feets? | Well theoretically if you were running 1 m/s and jumped out the back of a train moving 1 m/s you would. But if you aren't matching the difference perfectly your velocity relative to the ground will have you fall over one way or another because you're still loving relative to the ground. |
Why do we need to have a balanced nutrition while animals dont? | The balance that our body needs is a result of our tastes and historical scarcity. Our body needs some intake of fats, for example. We crave fats because they're scarce in the wild, and our cravings drive is to eat them when we find them. But we don't live in that kind of food scarcity. Society has made food abundant i... |
What exactly are the rules in Olympic slalom skiing? | It's based on time. You have to go in between the red and blue poles without missing a single miss |
Why do pharmaceutical companies pay for certain expensive medications for patients ("if you cannot afford your medication, Pfizer may be able to help")? | Back to actual question, they do it because they want to avoid legislation that would control their pricing. They can't afford to have public opinion against them and risk the people demanding national health care. |
Having just watched a documentary on Chernobyl and it's condition today, why is it that vegetation seems to be mostly unaffected by the fatal radiation which would kill us? | I have been to Chernobyl and Pripyat. If you ever get the chance to make the trip, I highly recommend it. Anyway, the simple answer is the radiation that would kill you isn't everywhere. In fact you can walk around quite a lot and in a lot of places with your radiation meter barely rising. While the area does have a hi... |
Why time theoretically stops at the Speed of Light | The explaination I know has to do with the consistency of the speed of light. If two observers measure the speed of light, both will get the same values, no matter how fast they are moving relative to another. Imagine a spaceship travelling at near the speed of lieght. Their experiment to measure c would be a laser bea... |
How does our mind decide what our voice sounds like when we read things in our head? | Unfortunately, we were not closely monitoring this thread. As a result, when it eventually gained attention, a large number of the top level comments were anecdotes, personal comments about which voice a specific user has in their head, or jokes - none of which are allowable as top level comments per ELI5 rules. Since ... |
Why does the marginal cost curve has an U shape? | Mainly has to do with the law of diminishing returns. Imagine you own a small fast food restaurant, and you want to sell as many burgers as possible. At first, you have just one worker, who handles prep, cooking, plating, and cashiering. If you add a second worker, your burger restaurant can be slightly more efficient ... |
Could Tony Stark be prosecuted for murders that Jarvis causes? | Prosecuted yes, but he'd buy the witnesses, intimidate the prosecutor, and talk the judge out of it. Who messed with Tony Stark and lived to tell the tale ;)? Yes, you can be prosecuted for the actions of the AI that you unleashed in the world, just like you can be prosecuted for the fine murder of your auto-aiming gun... |
How does therapy work for Anxiety and other personality disorders? | Don't take me as an expert but for the most part talk therapy is a method of getting you to come to appropriate or widely accepted conclusions about issues in your life, as well as providing generalized tools to help you in day to day life.

Cupping - What is up with this weird sports therapy that is giving the Olympians hickies? | I've had lower back problems for 10 years. A couple years ago I was recommended acupuncture and cupping because my issue is muscle related. I've tried many things for relief and regularly see a sports medicine therapist for massage. I finally decided to give it a try earlier this year. I have never had such relief as I... |
Why the government, federal or state, has not tried to step in and actually do something about Flint’s water crisis? | It's a local municipal issue. It's not a state or federal issue and has nothing to do with the presidency. |
Why do gay men commonly have higher pitched voices? | They don't, you just notice the ones that do. I worked in a gay bar and most of the guys are completely like everyone else, they wanted to drink beer and watch the game. Many had wives and kids. They just happened to like dudes, that's all.You should check out the documentary "Do I Sound Gay" on Netflix. It's pretty in... |
What is it about Asian culture that has them wearing face masks more often than others? Even outside of Asia? | Keep in mind that it isn't just to prevent yourself from getting sick. It is also to keep you from getting other people sick. |
How did we "solve" the Y2K problem? Was our solution completely thorough? | There was never really a problem. It was all sensationalistic journalism combined with a few people 'in the know' not really knowing. anything, almost everyone in IT at the time knew it was not going to be an issue The 'next' Y2k will be in about 20 years, but that will be another non issue to those who know |
Why do people hoard gold when they think society is going to end? | > if I thought society was going to regress to the dark ages, I'd hoard things like food, and tools, and protection. The people hoarding gold don't think society's going to collapse. They just think that there's going to be massive inflation that makes our paper money worthless. That's why they buy gold. Gold doesn't c... |
If the purpose of a clutch in a standard vehicle is to separates the gears so I can shift, why do the RPMs spike if I press the clutch too quickly? | Your car's engine is a 4-stroke engine; combustion occurs in each individual cylinder for ~0.5 of every 2 rotations of the crankshaft . So each cylinder has to complete it's 4-stroke cycle before it can respond to your throttle input, ie, when you let off the throttle, you still have a number of cylinders with big char... |
What are waves and how do they work? | Waves happen when you have a value that varies over a certain object. Also, the value of a piece of the object depends on what its neighbors used to be. Let's use a specific example - a slinky held by one end. What determines where each ring of the slinky is? It depends on where the last and next ring *used* to be. Thi... |
Why can I clearly see dust particles inside when a sun ray shines through but cannot see any while outside in full sun? | It's similar to why you can't see stars during the day. They dust is the same brightness inside and out, but needs the contrast of a darker background to be seen. |
why do some pills come in bottles, and some in blister packs? | One surprising reason for blister packs: suicide prevention. For example, in 1998 the UK switched all paracetamol to blister packaging to make it harder to overdose— you can't just dump out a handful, you have to individually punch out the pills. They also limited the number of pills in a pack. I think this applies to ... |
Why did they make us clean our mouths with fluoride in elementary school? | It's not cleaning your mouth with fluoride. It's exposing the teeth to fluoride to allow the fluoride ions to bond to the tooth enamel, changing the chemical makeup of it and making it stringer, so your teeth are less susceptible to decay. |
Why can't we manipulate some type of enzyme to allow us to digest plants? | We can digest plants. Just not cellulose, which is what you're probably referring to. There is an enzyme which breaks down cellulose, but it won't work very well in our gut - it needs a precise set of conditions to work . We can break down cellulose in a vat with carefully controlled conditions, and I guess you could t... |
What is exactly lower back pain and why does even a small injury sometimes take years to heal fully? | Short answer 10 leg lifts for 20 seconds each followed by 10 stomach crunch's for 10 seconds each. Not a medical anything, speaking of my own personal experience. 50 yr male. I've had multiple x-rays and exams and been told by multiple doctors that all my disc's look good nothing misaligned and that my pain is soft tis... |
What is the difference between pleading "guilty", "not guilty", and "no contest" in court? | No contest means you're going to accept the consequences as though you committed the crime, but are not admitting guilt. |
So what was B:\ drive? Why isn't A:\ drive the primary and how did C:\ become king? | Since this question has been answered very well so far I'll mention briefly that on a windows computer you can reassign letters to any of your drives. So if you want an A and B drive again you could rename any drive you have. You have options A through Z.Like many people, my first computer had one floppy disk drive - D... |
How does gene activation work? Aren't genes mere blueprints? How does a gene "activate itself"? | First off, you're wrong about how genes code for proteins. Essentially, the DNA in your cells gets copied into a different molecule called mRNA, which is similar to RNA except only one gene gets copied . The mRNA then leaves the nucleus and is translated into protein. Now, your question is pretty complicated. There's a... |
Why do royalty and popes change their names? | It's not just the Pope and royalty. In a lot of Catholic monastic orders, when someone joins, they change their name. The Franciscan monks and Dominican nuns responsible for my high school education explained that it was symbolic of a new life, a new identity. In their case, they would often take the name of a saint or... |
If the sun is getting hotter in billions of years does that mean that planets farther from us may become suitable for life (while earth may not). | My high school teacher had an interesting theory about how to create a thicker atmosphere on Mars. He suggested taking a space shuttle full of earth's trash and crashing it into the planet to burn which would release greenhouse gasses into the atmosphere. Interesting approach. |
Why do people write C.E. instead of A.D.? Why not change the calendar? | Changing the calendar is a major task that everyone has to agree to. Referring to CE instead of AD doesn't require changing the calendar, and it removes the religious connotation.One alternative is the [Holocene calendar], a simple fix . Just stick a "1" on front of current dates, making this 12015 H.E. Since it fits r... |
how casinos can refuse to pay a jackpot, claiming the machine is broken, but not pay back everyone who played and lost? | A few years ago, my brother came home for the holidays. We went to MGM casino after a night of partying in Detroit. He won a jackpot at a Roulette machine, but it didn't payout the $1,000 or so he won. I stayed by the machine as he went to complain. They said they couldn't do anything and said we were lying. The only r... |
Why do people shake hands when they meet? | Not sure if this is true, but I learned when I was a kid it's to show that your 'fighting' hand ie. the hand you would hold a sword or spear in, was empty and therefore came in peace. |
Why does reddit search fail when google search of reddit works? | Google tries very hard to find your result, including looking for results that don't quite match what you typed but almost match. Reddit search will fail if your query contains a word or spelling that is not identical to what is found in the actual post. Google spent a lot of time and money making their search more pow... |
Why do my teeth start moving back to their original position when I don't wear my retainer for a few nights (after 15 years of wearing it)? | There are fibers that go from tooth to tooth called transeptal fibers that connect the tooth together. There are many different fibers but the transeptal fibers are the ones that are suspected to be responsible for the teeth shifting. Braces create tension and pressure to shift your teeth and bones but it has a hard ti... |
If a day would last for 48 hrs, for how long would humans sleep and be awake ? | There are two possible scenarios. - We take humans as we know them, and put them on a planet with 48-hour days - We imagine that humans had evolved not on Earth with our 24-hour days, but on some different planet with 48-hour days Each of these would have a different answer. - In the first case, the average person's bo... |
How the TSA continues to get funding and exist despite all the public outcry and disapproval. | There's not actually that much public outcry and disapproval. You see things about the TSA on the news all the time, yeah. And that stirs up controversy and makes people talk about it. But most people really don't give a shit in the end. Check out [this] article. It shows how even though support had decreased, there's ... |
When a jar won't open, why does hitting it from the bottom, or tapping the lid on the edge of the counter, work to make it easier to open? | A jar won't open is often due to pressure. Hitting a jar from the bottom rarely works for me. What I do is put it under running hot tap water for 30 s and it usually opens. When it's heated up, pressure in the jar changes. Someone please correct me if I am wrong |
why there aren't any animals that photosynthesize | This is pure speculation on my part, but I would guess that it's because it's relatively energy inefficient. Animals tend to eat extremely concentrated forms of chemical energy. For example take a cow, which grazes on grass all day. It might eat 50 lbs of grass. That grass, however, took 20-30 days to grow, using photo... |
Why are Google, Microsoft, Yahoo, and Cisco all supporting CISPA when most of them vehemently opposed SOPA? | SOPA = Gives the government the power to shutdown websites because companies think the website stole the company's property.
