this picture disappears when you stare at it - why?
I stared at it for a good 2 mins and nothing disappeared. Am I doing something wrong? I am 100% sure I'm not color blind as I've been tested multiple times for work.When you stare at something without moving your eyes, your photoreceptors become super saturated with no new stimulus and therefore, your vision fades to grey. With a movement of your eyes, the photoreceptors receive a new stimulus and you see color again.It's because after a while your phone wants to save energy and at first dims and then shuts of the display light completely.
Why do credit card scanners have to ask "credit or debit" instead of figuring it out automatically from your card?
Here in Canada a lot of the machines don't, particularly tap and go can be enabled on both debit and credit card, and you don't have to choose anything before tapping.
When I get a headache, what is actually hurting? Is it my skull, my brain, tissue? What??
First you need to figure out what kind of headache. Migraine: unsure as to the cause Tension: muscles refer pain to certain areas. Some muscles in the neck refer pain to the head Cluster: unknown; terrible headache you wouldn't wish on your worst enemy. Finally, dehydration can cause headaches too. This would most likely be the meninges/blood vessels/nerves causing the issue. This is all off the top of my head.
Are there mindsets that manifest themselves and create mental illnesses?
It's basically a feedback loop. The kind of mindsets which make a person more likely to develop mental illness are often caused in the first place by mental illness itself. For example, people who tend to look at the negative sides of things, are very self critical, and lose hope easily, are very likely to develop depression. However, all of those things are also symptoms of depression, so the line can be very blurry between a bad mindset and a mental illness, as mental illness makes the bad mindset worse, the worse mindset can make the illness worse, etc.
How hard would it be for a human to change away from a 24 hour day schedule (for instance living on a planet that had 30 hour days)
My body has hated the 24 hour schedule my entire life. After 8 hours of sleep my body seems to want to be awake for about 20 hours. There have been times when I could just allow this to happen and I found myself much happier and more motivated. Unfortunately that doesn't work out as I have to work for a living. I can push myself into an acceptable pattern for a 24 hour day, and after a few weeks it becomes natural and I usually don't even need a clock to assist in getting up and going to bed at the right time. However one late Friday or Saturday night and my body resets.
If I send a heater into space and turn it on, where does the energy form the heater go?
Electromagnetic waves don't require an atmosphere to travel, therefore the energy will behave pretty much like it does anywhere else.
How is the meat and chicken industry meeting the global food requirement without wiping out farm animal populations?
Your estimates for global meat consumption seem a little high, but let's go with it. A five-pound broiler-fryer chicken can get to market weight in as little as five weeks- let's call that forty days. That means that every person who eats, on average, one chicken in four days needs there to be ten chickens alive at any given time, to keep him supplied. Plus one or two more, for breeding stock and eggs. If everyone ate that much chicken, there would need to be around eighty billion chickens in the world. That's a surprising manageable number. What's the problem?", 'The planet is home to ~20 billion chickens. Chickens that are eaten are generally very young by human standards; two months old at slaughter is fairly typical. So the stock of chickens is regenerated very quickly to meet the demand for chicken meat. Also worth mentioning that the average chicken consumption rate is far less than 1/4/-1/2 of a whole chicken a day.
Why does WLAN know my exact location but LAN doesnt?
802.11 WiFi radios don't go far, so SSIDs can be duplicated as long as they are far enough apart. The WLAN doesn't know where you are. Perhaps your iPhone says its location accuracy would be better if you turned WiFi on, but that's an artifact of how iPhone Location Services work, not WiFi WLANs themselves.
Why does tickling myself not make me laugh?
Same reason why blowing yourself feels a lot more like sucking a dick than it does feeling like you're getting your dick sucked.An interesting piece of fact is that schizophrenics can actually tickle themselves. _URL_0_', "It has to do with the uncertainty of the brains inability to predict motor feedback. Timing is also of the essence in determining why we can’t tickle ourselves. Since we’re able to predict the moment of contact, it loses its thrill. This too was proven by the study Alan Bellows was talking about, where a robotic arm was used to tickle the palm of the participants. The robot was controlled by the participant, so it was effectively self-tickling. When the person directed the arm to tickle, it did so immediately and thus there was little ticklishness. This robot had an added feature, however, in that a time delay could be introduced. As the time delay increased — and predicting exactly when the tickle would be delivered grew more difficult — ticklishness reportedly increased.
What causes you to go mute or be born mute?
I am not a specialist, but I have worked with speech pathology before. A couple things can cause muteness. People who are deaf and hard of hearing can have deaf related muteness because they never communicated verbally. Disability of the tongue, vocal chords, lungs, or the mouth in general can cause muteness. Sometimes autism can play a role in causing muteness, or selective muteness due to social anxiety. Injury to the frontal lobe of the brain, that controls motor and sensory function in your body, can cause muteness due to the inability to move your mouth over time. You even have a special area in your brain called the broca's area that allows you to mentally process language and communication: stringing words together and the ability to assign sound to meaning and what-not. Injury or disorder to this area would greatly affect your ability to verbally communicate, and thus could cause muteness. tl;dr: It's difficult to pin-point what causes muteness, as it's more a product to injury, disorder, or potentially anxiety.
why do people get those painful inflamed taste buds?
I feel you man. I finished a bag of David's ranch sunflower seeds today. My tongue is quite sore as well. Maybe the salt?", 'My mama always called them dead taste buds. Proper name is transient lingual papillitis. _URL_2_TIL I have a geographic tongue and so does my son.
How can locks/padlocks be mass produced whilst still being unlockable only by their individual key?
Most people don't realize that not ALL locks and keys are unique. Even autos have keys which duplicate those of other similar brands. It's just it's so rare that a key to one car will start another, it's not often seen. But it does occur. Same is true for house keys. If people REALLY knew how easy it was to pick a lock, they'd think twice about buying cheap locks .
Why would someone not want their baby to have a birth certificate?
I think you are all worried over nothing. This kid isn't going to need a birth certificate for getting an education, or a drivers license. Between the infected lotus placenta, lack of vaccinations and the environment it's going home to, if be surprised if it sees its second birthday. This just infuriates the ever loving shit out of me. The state needs to intervene and rescue this kid before it's too late.
How are famous actors/actresses able to stay "closeted" as gay and not outed by TMZ or other paparazzi?
They have so many people working for them that they are able pay people off to not say anything. A lot of people already know before it's broadcasted but after awhile when the celebrity is really famous it doesn't matter anymore so they just come out clean
How was the Holocaust able to happen? Didn't other countries realize that it was a horrific thing and all try to stop it?
No, they didn't. The idea of labour camps and prison camps were not uncommon. Almost every country had remote camps where people could be taken. Everyone outside of Germany and His allies simply thought that these camps were prison camps where the Germans were taking politician prisoners. This was bad, but it wasn't seen as grounds of starting a war. It wasn't until Germany was invaded and Allied Forces encountered these camps that the horrors came to light. Band of Brothers has an entire episode dedicated to retelling the story of the 101 Airborne first encountering a camp where they didn't know the prisoners were Jewish. They thought it was a labour camp for criminal or a camp for political dissidents.
Why do we still vote for a representative when technology could allow everyone to vote themselves?
Every year congress looks at *thousands* of piece of legislation. They require the full-time support of dozens of people to keep up with all the details. It wouldn't be reasonable to expect the general public to be able to keep up with & make informed decisions on all of them. Beyond that, congress routinely debates & revises laws in the process of passing them. There's no reasonable way to expand that to the whole population.
What is the difference between Advil, Tylenol, and ibuprofen and how exactly do they alleviate pain in the body?
Related Question: Why do I not seem to feel any great effect from it? Is it more effective to some people then others? Or am I just trying so hard to think it doesn't work?
Why would a working class person want to vote for a candidate who favors tax breaks for the wealthy?
Because there are the President of the United States of America is not a single-issue position. It's unlikely for somebody to agree 100% with either candidate and you have to cut your losses somewhere.Because people soak up ideas proffered by available media, all of which is owned by people who do favour tax breaks.You're assuming here that there is exactly one issue at stake in elections.

Why are people allowed to carry handguns, but I can't carry a sword?
In Indiana it's perfectly legal to carry a sword. However, local business have the right to reject you for carrying it into their place.
What is the logic behind multiple life sentences?
You get sentenced per crime. There's not necessarily a particularly good incentive to *not* simply do it this way, and incentives to *do* do it this way. What if, for instance, the guy is found innocent of one of his murders, but still guilty of voluntary manslaughter. Do you now have to create a whole extra stack of paperwork on how to refactor a criminal punishment if the degree of guilt or the scope of guilt changes? Do you have to have a new trial sentencing phase? Why not simply keep the charges separate, and thus you can address them separately.
How can birth control methods still cause weight gain even if your healthy diet and exercise remains consistent?
> even if your healthy diet and exercise remains consistent? Because there is a good chance it isn't. Changes in hormones levels can affect appetite and energy levels, so expending the same effort on diet and exercise may not achieve results. Also, they can also cause more fluid retention, which makes you bigger and heavier, but is not necessarily unhealthy.
Why aren't real life skills, such as doing taxes or balancing a checkbook, taught in high school?
Your average person coming out of high school will likely be using a 1040 EZ tax form for quite a few years, assuming they don't own property or are married or anything like that. It's called EZ for a reason. They tell you exactly were to find what numbers you need, where to put them, and what numbers to add. They're basically idiot-proof; all you need is common sense and elementary math skills.They are, but nobody seems to remember them. I learned the basics of balancing a checkbook in Economics. As for doing taxes, the code often changes yearly, if not quarterly for some, so anything that gets taught in high school would go out the windowWe have to take a consumer education class to graduate high school, and we learned everything in that class.Because traditionally, parents actually had an active role in teaching their children life skills. Schools weren't designed to teach people such basic trivial matters, it was assumed the parents would. Now parents don't, and schools have no obligation to.Because that shit isnt asked on the standardized tests', "I actually took a Home Economics class in 7th grade in Bloomington, CA in 2002 which taught the basics to balancing all this stuff out. They also made it a requirement to take care of one of those robot babies that cry every hour for 3 days. Wasn't too fun, but I got an A.
Many muslims drink a lot and have premarital sex a lot but still avoid pork explaining that it is against their religion. Can someone explain this kind of reasoning?
I've known a few who had been told so many times that pigs are disgusting, unclean creatures that they simply had no appetite for it either way. Knowing pigs, Muslims might be on to something.
Why is the play button a sideways triangle, the pause button parallel lines, fast forward button (and so on).. how did this come about and why is internationally recognized?
Not able to answer your question, but I just thought I'd let you know that these are commonly called Transport Controls. Just FYI.
How do cops give tickets to pedestrians and people without an ID?
I've actually seen this happen. I arrested a girl for shoplifting, and she gave everyone a fake name, fake info, etc. Said she had no ID. He pulled out this little box, scanned her finger prints, and pulled up all her information. Busted! Obviously this only works if somebody is already in the system though. Otherwise, if someone commits a crime and there is no way to obtain their information, and the person refuses to identify themselves, the cop will take them to jail.
Why did humans start using base-10? Is it because we have ten fingers? Are there other cultures on Earth that use different counting systems?
Base 10 is the most logical, because humans generally have 10 fingers. So most of the world uses that. But that's not the only numeral system the world currently uses, or has used. Many Asian countries count to 12 by using the thumb to point to the various bone segments on the remaining 4 fingers. In modern times, binary or base 2, octal or base 8, hexadecimal or base 16 are commonly used in computing. In the past the Sumerians used base 60, which is why we have 60 seconds and 60 minutes. _URL_0_ See also _URL_1_
Why do the suns rays appear hexagonal in photos and videos?
[This is a pretty good demonstration] of what other people are talking about here. You can see it's got a clear geometric shape, and this is because of the shape of the iris in the camera lens. The iris is made up of various blades, and would look something like [this], which would mean that light would be let through in that shape. There are ways that you can play with this using a camera, and by cutting an appropriate shape you can get [custom bokeh effects.]
with all the breakthroughs in tech that enable workers to do more faster, why are we working longer and harder?
I don't think we are. My grandfather worked like a dog since the age of eight. He wasn't alone. My other grandparents took 11 days off each year--total. People used to work hard and long.
Am I wasting energy if the phone charger is connected to the socket but the phone is not connected?
Look at the text on your charger, where all the technical information is. Most likely there's a marking like a Roman numeral inside a circle. That's the [International Efficiency Marking]. All my phone chargers are marked with V and are rated for < 50 W. That means it consumes less than 0.3 W when plugged into the wall but nothing is plugged into it. At $0.12/kWh, that's *at most* **$0.32 per year** per charger. There's also a VI category that uses 1/3 that much, which your charger might satisfy. Quick rule of thumb, BTW: 1 W left on 24/7 is about $1 per year of electricity. ", 'Here's a question to think about- if the charger is "wasting" energy, where is that energy going? It has to go somewhere. In this case, the only place it can go is to heat, since it isn't connected to an energy storage device , it isn't giving off light or making any noise. If you feel your charger, is it hot? If not, then it can't be wasting very much energy, or at least enough to care about. And I suppose if it is hot, and its winter, well, then I guess your heating system doesn't have to expend as much energy to keep that little bit of your home warmPhone chargers are peanuts typical idle consumption is about 0.5W. However it pays off to check all your devices which have a standby mode with power consumption meter. For example early PS3 consumes almost 200W on standby.
What is about AIDS that actually kills you?
HIV uses your body's CD4 helper T cells to replicate. Each newly replicated HIV particle pinches at the cell's membrane as it buds out of the cell before the cell eventually loses enough membrane, shrivels up, and dies. A normal CD4 cell count in an average person can be anywhere from 900-1200 . As the HIV progresses, it can mutate over millions of times per day. this battle between your CD4+ helper T cells and HIV can go on undetected for over 10 years. Within those ten years you may see a gradual decrease of CD4 cell concentration. AIDS is defined by two things: a CD4 cell count below 200, or the presence of one of the many opportunistic infections . After somebody is officially diagnosed with AIDS, they generally have around 2-3 years before they die from the opportunistic infections. Remember that AIDS is not a virus, it is a syndrome as a result of HIV.
If fat is one of the best insulators, why do obese people generally wear the same amount of clothes as average people?
I'm not a scientist or anything but I remember reading an article suggesting that part of the problem of obesity was that people with slow metabolism have less brown fat cells which are the ones used to keep the body warm. People with faster metabolisms often burn off excess calories as heat while sleeping for example.
If monopolies are illegal, why are ISP's allowed regional control over huge areas so there is no competition?
It's technically not a monopoly. Nothing is stopping the other providers from running a cable, they just don't think it would be profitable.
Why are dull knives more dangerous than sharp knives?
One thing I haven't seen mentioned here is that a sharp knife will cut you CLEANLY. The wound will heal pretty easily a a result. A dull knife will tear the shit out of you. It leaves a ragged wound that is much harder to heal, and more likely to scar and scar badly.Sharp knives cut through things easily. Dull knives require you to use a lot of force to cut things making it easy for them to jump around wildly if you lose control.When you're using a dull knife you're more likely to put more force behind it or get more frustrated which is more likely to lead to you cutting yourself.
Why arent placebo antidepressants prescribed instead of standard ones for mild/moderate depression if they are just as effective with less side effects?
This has been answered really well already, but there's one aspect that I haven't seen mentioned yet. If placebo started being prescribed in place of medicine, then word would get around that this was happening. Then people would be more skeptical of the medicine they were being given and concerned that they might not be taken seriously by their doctor. This would create many very distrustful doctor/patient relationships and lower the overall quality of care. That being said, it WOULD be interesting if you could sign an agreement stating that you agree to be given placebo under the doctor's discretion. That way you'd voluntarily agree to the possibility of being given a placebo if the doctor thought it would benefit you similarly to the real medicine.
What's the difference between 23.976 fps and 24 fps, and why is 23.976 used?
23.976 is what's used on TVs, because TVs aren't actually 30 FPS - they're 29.97 . When playing 23.976 FPS on a TV, you map 4 film frames to 5 video frames.
What's the difference between Type 1 and Type 2 Diabetes? Please and thank you!
In the back wall of your stomach you carry an organ called pancreas. The pancreas has two main duties, secreting enzymes - chemically active proteins that facilitate digestion - to your digestive tract, and producing insulin. Insulin is a hormone which is produced when there is a lot of glucose in your blood. Insulin helps your cells taking in sugar for use or storage and reducing its concentration in your blood. In type 1 diabetes the cells of the pancreas which produce insulin are damaged and no or too little insulin is secreted. In type 2 diabetes the body's cells have become immune to insulin due to a long exposure to high levels of insulin. Although insulin is produced - a lot of it actually - or even injected, cells do not take up as much of it as needed to clear the bloodstream of sugar. EDIT: spelling
Why does forcing pornstars to wear condoms kill the porn industry?
For real, I don't like watching porn where the actors use condoms. But then again I never pay for porn so my preference has no effect in the industry.
Why has there been a push to end Flash on the internet and how does Adobe feel about it?
If I recall correctly, Adobe actually wants Flash to be replaced. It's simply not needed anymore, and they probably don't want to fund it either.
Why were single shot rifles used in European Armies despite multiple shot rifles being readily available by 1875?
Because lever-action rifles are designed to use [tube] magazines, where the rounds are stacked end-to-end. It wasn't possible to put big rifle rounds, which have pointed, aerodynamic tips on the front, into tube magazines since the point could set off the round in front of them. The military needs to use those type of rounds, and it wasn't until bolt-action was invented that there was a repeating mechanism that could handle them.
Why is high-caliber ammunition (such as .45 and up) more common and accessible in handguns and pistols than in rifles?
Two reasons. One: long cartridges don't fit well inside the grip part of a handgun. Two: short, fat cartridges with heavy bullets are generally designed to burn faster to take better advantage of shorter handgun barrels. Rifles have longer barrels, so their longer cartridges with less massive bullets can be made to burn longer but end up accelerating to a faster speed once they leave the long barrel. Basically, if you can't make your bullet go fast, you should at least make it bug and heavy to partially make up for it.
What would happen if you were arrested and after you were read your rights, when they ask if you understand, you say no?
It's a Miranda warning. You had the very same rights 30 seconds before he started talking. You should never talk to the police. _URL_0_
Why are there countless numbers of animal subspecies, but no human subspecies?
Because we killed all of them. There used to be a time where there were a few different human-type beings that lived concurrently. Homo Sapiens weren't the strongest of the bunch, rather, we were the smartest, so we were able to conquer the other species of human-like beings.
Why do people spend over $150 to buy "Professional Mechanical Keyboard"? What is the difference between the regular keyboard and mechanical keyboard?
for me it's mostly for the feel you get with every key press. It feels way nicer than a regular membrane keyboard, and you use less force to activate each press which is nice too it really comes down to personal preference, why do people get different brands of car, watch, phone, computer, etc. as long as you enjoy it, why not? for more, check out /r/mechanicalkeyboards!
Why does the search for extraterrestrial life revolve around water?
As we understand it, all life requires water. Sure, there could be life that lived in hydrogen sulfide gas but we'd have trouble recognizing it as life if it was right in our faces; recognizing it from outside the solar system would be nearly impossible. It's only in the last 20 years or so that we've even been able to detect and identify planets outside of our solar system. The amount of information we can gather from them is miniscule - about all we can do is tell the size/density, distance from the sun & get some information about the makeup of the atmosphere. Our only hope right now of identifying life would be to see a warm-ish, solid planet that has an atmosphere that looks sort of like ours. or for SETI to get ridiculously lucky and pick up radio transmissions.
Why is it that I can by a 2" thick novel for ~$6, but a 20 page children's book will cost me $15-20?
Not many people would by a book costing that much for themselves however when it's for your kid? Money is not the primary concern. I used to work in a bookshop, those books are on lower shelves for a reason, so your child will see it and the harass you into buying for them. Its smart and a little bit evil.
- why do we put salt in our water pre boil?
While adding salt raises the boiling point of water, it also lowers it at the same time. Bit of a paradox, bear with me.So, the salt raises the boiling point of water. Everything is good, everything is fine. But, water has a high heat capacitance and salt does not, comparably. When heating straight up water you have the boiling point of 100c. Adding salt will raise this temperature to 101c or so. But, and this is where the magic happens, the salt in the water can heat up much quicker than the water itself. So this results in the water boiling in a quicker amount of time because the faster heating of the salt content. Not sure if this is what you wanted to know but here's this tid bit.
Why don't they use lie detectors for the every case ?
They're not too good . They measure things like palms sweating, changes in breathing rate/depth, and heart rate. They can be useful in interrogations, as a way to prompt a confession, but they aren't admissible in court.
Why Tim and Eric are considered funny.
I'm not so sure it's a generational thing. I enjoy their comedic stylings because they take slices of life that would normally be considered mundane and turn them on their heads in a subversive way. Be it by exaggerating it, or making it disturbing, or even goofy. Their works are practically performance art.Can you explain why the things you like are considered funny?
Magic the Gathering's competitive scene
There's rules restricting how many of what cards you can use. The rarest cards are no longer allowed - everything you can use is fairly widely available. Once you're at a 'serious' level, it's assumed that everyone has access to the same cards so nobody's really getting an advantage from buying better cards. It's like most car racing formats - you've gotta spend a lot of money to get to the top level of competition but there's rules in place that limit just how far you can go. The other popular tournament format is the draft - where players all have to choose cards from a common pool rather than bringing their own cards in. This puts more emphasis on the ability to build a deck with limited resources. As for getting really lucky to win a game - they don't just play one game. They'll play multiple games & chose the winner based on who wins the most .
Why isn't working in a very physically demanding job considered "enough" exercise?
I'm not a doctor. I'm also going to be lazy and not read other comments. My guess is your doctor is primarily concerned with exercise as a form of cardiovascular health. A brisk walk sustained for 30 minutes is better for heart health than your rounds for 8 hours. A 30 minute run is even better. Going to the gym and lifting weights will benefit your job performance as well as your physical health more than you think. You DO have a physical job and it's probably more strenuous than your body would like. Not only will proper weight lifting make you stronger , it's going to strengthen all the accessory muscles you're already using daily to do awkward things, like lift a resident from the tub. You'll learn through weight lifting what proper form is and how it feels to truly lift with your legs and not your back, and you'll be significantly less likely to pull a muscle from your job. TL;DR - Doctor cares about your heart health, keep heart rate elevated for 30+ minutes. Lifting weights will reduce injury risks.
With so much technology moving to GEO orbit, how do they prevent collisions?
It's also worth noting that a geostationary orbit can only occur at about 22,000 miles from the earth and directly over the equator. That means all these GEO satellites are sharing a circle that's over 120,000 miles around. That's a lot of space to share, especially when they are not moving from their spot in that circle.
Why you would want an LLC for your business. (sole proprietorship)
It's not about the amount of money you could lose in the business, it's about a separation of your personal assets from business ones. If your business screws up and gets sued, with an LLC they can only go after the designated business assets, with a sole proprietorship, your personal property come into play. Most states also require you to pre-pay a minimum amount of income tax each year. In California I think it's $800", 'Would a writer who intends to self-publish need an LLC?
What has changed in the last 4 decades so that it now takes two incomes to maintain a household?
Wages have gone down if you adjust for inflation. The current system that companies work under doesnt incentivise increased wages, its much more beneficial to them to spend the money on their stock. So for example we had the issue of almost insane bonuses given to top CEO's, in order to battle this now bonuses have to reflect the companies stock on the market. If it has gone up higher bonuses. How do you increase the stock value? You have payouts on your stock so people want to buy it. Also the stock market is used as a sort of tool to see how well a company is doing, so stock payout is getting more and more important to companies, but they have a limited amount of money.
The difference between .rar and .zip
A lot of people are focusing on things like algorithms and implementation features . This is NOT the fundamental difference between ZIP and RAR! ZIP is a file-based archiver. Each file you ask it to compress will be compressed individually. These compressed files are then assembled into a collection, which is your .ZIP file. RAR on the other hangd is a solid archiver. It looks at the entire set of files you give it, and compresses them all together into one big wad of data, this is a .RAR file. Why ZIP > RAR: * ZIP both compresses and de-compresses faster, especially for the case of decompressing a single file . * ZIP can recover from errors better . Conversely, why RAR > ZIP: * RAR can take advantage of similarities *across files* to achieve far higher compression ratios than ZIP.RAR has better compression, and allows for segmenting
If carbon dioxide is bad for you to inhale, and people provide it when you breath out, Wouldn't the carbon dioxide do any damage to the person getting mouth to mouth?
Pure carbon dioxide would be bad to inhale, especially for a prolonged time. OTOH, if a person is not breathing, the air you exhale contains carbon dioxide but it also contains some oxygen, which is good. So, some oxygen is better than no oxygen . If you could arrange to blow ordinary air instead of what you are exhaling, that would be better, but probably would require a hospital or some such. So, net, net, using your exhaled breath is better than nothing. Still, when they can breathe on their own, let them. BTW, pure nitrogen, pure laughing gas, pure helium, are all unsustainable for breathing. But you can do them for a bit. In the case of helium, folks do it since their voice sounds strange.
Why are Greek and Roman (and other) stories about gods considered fiction but the bible isn't?
Despite having a bias on this matter, I'll try to be as non-biased as possibe. It has to do with what we know and what we didn't know. Many Greek and Roman gods were based on forces which were yet to be understood at that time. Lightning, wind, the currents, the sun, all of these were beyone their comprehension. So, once these were able to be naturally explained, the gods were used as a reason, and then died out. We are currently in a bit of a dying out stage. The Bible explains origins of the universe, morality, and other things still denied by much of the world. Now that a definite reason is out there, God is being used as a reason, a cause for everything. If current models are correct, it is likely that Christianity and other major religions will take the backseat within the next couple of decades. It shows that the more that we know, the less we need to guess.
Under what powers do the "Developed" nations of the world tell other nations that they can't have nuclear weapons, rockets, or satellites?
Nuclear weapon technology is governed by the [treaty on the Non-Proliferation of Nuclear Weapons]. Nuclear powers that sign that treaty promise never to share nuclear weapons technology, and to promote the peaceful use of nuclear technologies; non-nuclear powers that sign that treaty agree never to try to develop nuclear weapons, and in exchange they benefit from the sharing of peaceful nuclear technology. Signing that treaty is voluntary . However, countries that don't sign that treaty tend to be treated very poorly by other countries . There are no treaties that generally restrict access to space, rockets, or satellites. However, since each country owns the airspace over their country , a country cannot send stuff flying over other countries without permission.I think the spirit of OP's question is may be like this "The US, Canada and the other big boys have nuclear weapons so why can't just anyone get them? And under what authority do the big guys say SORRY NORTH KOREA YOU CANT HAVE THEM"? The truth is there is no authority but what you make of it. Sure, it's a big hypocrisy that the US can have nukes but will try to deny basically everyone but their best friends that same right. The US can do that because life is not fair and the US is really big and wields a big stick. So, there's no real enforceable law out there except that if you don't listen to the US you can wind up getting the short end of the stick .They have big armies and big farms. When people give you food and threaten to hurt you if you don't obey, you tend to respect them and do as you're told.
How can 2 (3?) gas atoms (H & O) form a liquid (H2O)?
I'm not sure exactly what you're asking but I'll give it my best shot. Water molecules are liquid at ambient temperature and pressure because they don't have too much energy to not be in an ordered matrix solid, but not enough to form freeflowing gas. That's thanks to water's molecular structure and its asymmetrical shape making it a polar molecule . H2 and O2 on the other and are symmetrical molecules so they stay gasses at ambient temperate and pressure.Firstly, hydrogen and oxygen are not "gas" atoms. Hydrogen as a molecule, H2, and oxygen as a molecule, O2 , happen to be gases. Oxygen is highly electronegative , hydrogen not so much. When you have 2 hydrogen atoms joined together in H2, each has the same pull, and the molecule has no distinct region where there is stronger charge than another. The same is true for two oxygen atoms joined in O2. A pair of very small and light atoms, with no distinct charge to cause them to bond to something, will be a gas at room temperature, since it takes very little energy for them to enter a gaseous state. Water however, contains 2 hydrogen atoms and 1 oxygen atom. Since oxygen is much more electronegative than hydrogen, it pulls the bonding electrons more strongly towards itself, meaning the O end is more negative, and the H end more positive. This charge is significant enough that water will be attracted to anything with a bit of charge, including other water molecules. This attraction will keep water together, and mean it takes much more heat energy to break free and enter a gaseous state.
Why is it not possible for earth to be flat?
The basis for celestial navigation for centuries has been based on the fact that the earth is spherical. GPS only makes it more certain: how could satellites orbit a flat earth? Columbus knew the earth was round; he just thought it was smaller than it is. How can all those people circumnavigate the world if it's flat? How does the International Date Line exist?
Questions about shapes/gender recognition in a 18 month-old
goat", etc. where he creates sub-folders of generalizations now dogs are the ones that bark regardless of it being white and black or just brown So for your child, probably she/he just learned that moms are female people . She will just need to keep specializing the concepts to be able to differentiate mom from woman, from girl in other words, she might think right now that "mom" means female .. and eventually she'll get specialized info.. just let her explore and ask questions and explain which is a mom and which isn't in a game environment and she'll get smart about concepts real quick', "Yes, gender can be recognized by children that young, but you can't always be sure what they mean by a given word, especially when their vocabulary is so small. My daughter when she was a similar age called her mother, myself, her grandmother and her grandfather all 'Mommy'. To her it just meant adult/parent etc. Eventually she learned more words and started to differentiate.Yup, 18 month olds are around the age when they discover that adults categorize people into two genders. Think how much we must subconsciously reinforce this all the time for kids that young to already have it down. A kid I know at that age was on a bus, pointing at people and whispering "That one has a penis, this one has a vagina" etc. Luckily they spoke a language that wasn't commonly spoken where they lived
What is so good about Google Fiber?
Well if you go on the front page, you'll get an example of one business that is pretty much the exact opposite of Google Fiber, and then it will be easy to see why Fiber is such a big deal. Specifically, take a look at Telstra, the Australian internet monopoly, and you'll see why internet can be really good or really bad depending on things outside our control. In short, we're pretty damn lucky to have Google Fiber. _URL_0_
Why can't countries like Japan with so many zeroes in their currency just remove a few?
If Japan were to proclaim that 100 yen is from now on going to be called 1 yen, it would require recalling and exchanging every last bit of currency in existence. All bills and coins minted before a certain date would from then on be worth only 1/100 of their face value. Until all extant currency was retired, close attention would have to be paid to the dates to ensure that people weren't robbed of their savings. There is just no reason to do it. International financiers are perfectly capable of dealing with numbers.
How do you “crack” a game? Why can’t you just send the files of the game to someone so they can play it?
For games with an online component, it is pretty easy. Each copy is given a unique number, and if two copies try to play at the same time, something fishy is going on. Even offline games and be protected this way by requiring an internet connection when you install. Games are cracked by circumventing the code that does this check, which means rolling up your sleeves and diving into 1's and 0's. In some was online distribution is easier, because the protection is managed by a delivery service like Steam. Crack Steam, and all their games are now cracked.
I watched "Honey I Shrunk The Kids" last night and wondered: could a human being function if they were suddenly shrunken down to the size of an ant? Why or why not?
If a shrunken human had the same intelligence, then the atoms inside him/her must have shrunk . After all, if you were the same size as an ant, and your atoms were the same size, you wouldn't be much smarter than an ant. So, to retain your memories/etc your individual atoms have to shrink. But, if your atoms were much smaller than those around you, you would suffocate. The oxygen atoms around you would be incompatible with your body. Better bring a scuba suit.
Does DNA only become dangerous when it creates proteins with that intent?
It's outside of the scope of your question about CRISPR, but there are strands of DNA called transposons that can be harmful to an organism. They are segments of DNA that can copy themselves and reinsert that copy back into the genome they originated from, sometimes disrupting a healthy gene and causing diseases such as cancer. They do usually require a protein, which the transposon sometimes codes for, to copy themselves in nature, but if you simply introduced a bunch of these transposons into a cell just those strands of DNA might be enough to cause damage. They basically function like a DNA parasite at their worst. There's much more to them than this though, and not all of it is bad. This is just an example of a DNA molecule itself being potentially dangerous.
Why do identical twins have different fingerprints?
Identical twin here! My brother and I have several fingerprints that are virtually identical. We've also been told by a dentist that our dental records are indistinguishable. I guess we were pretty congenial in the womb", 'Because one of them is evil and one of them is good, And you need a way to tell the two apart.
Why don't professional basketball players backboard alley-oop to themselves in-game more?
You have to be pretty much head on, otherwise the ball bounces away from you. A big man can't be in the way or he'll get the rebound. The guy guarding you can't get in your way or try to block you out from the rebound, otherwise you won't get to the ball. If there's no big guy at the rim and you can easily get past your defender, why not just take it in for an easy layup?
What health aspects can easily be monitored/measured via ones mouth
Dentists can apparently tell if you're bulimic because the repeated stomach acid in contact with teeth will damage the enamel.
How can creatures like wolves and lions survive without brushing their teeth? Do they have an evolutionary advantage or do they succumb to dental issues like humans?
They don't live long enough to have any serious dental problems. That and their diet isn't filled with sugar, they eat meat and that's it.
how a turbo works in your car.
Two things must get into the cylinder of the engine for combustion to happen; fuel and air. The more fuel and air you can get into the engine, the more power it can create. Without a turbo, the air is sucked into the cylinder when the piston goes down. A turbo is a fan/pump/compressor that forces more air into the engine, which means it can use more fuel and thus make more power. The fan of the turbo charger is powered by the exhaust as it leaves the engine. So it's taking something would otherwise be wasted and using it to make the engine more powerful.Hot exhaust gases flow through a turbine, which causes it to spin. This turbine spins a compressor, which compresses air and forces the intake manifold pressure higher. More air can then rush into the engine during the intake since it is at a higher pressure. Since there is more air, more fuel can be burned per combustion because the "optimal" amount of fuel is related to the amount of air in the chamber. This larger amount of fuel produces more energy when burned. more air = more fuel = bigger boom = more powerIt is an air compressor which increase the air intake and causes more fueled to be burnt and increase your horsepoweras someone who just purchased a used car with a turbo: VACUUM LINES. VACUUM LINES EVERYWHERE.
Why were the European Colonists not ravaged by American disease unlike the Native Americans who were ravaged by European/African disease?
Europeans, due to the thousand years' advantage in domestication, had immunity to all sorts of diseases. When they came to the New World, the locals were just wiped the F out by those diseases as they had no immunity. New Worlders had much, much less exposure to animal borne pathogens in close proximity and had very little immunities that Europeans didn't already have.
Why is the face so important in determining how attractive someone is?
In terms of evolution the more feminine women and more masculine men are attractive because they indicate that the owners of such characteristics possess good genes. Symmetry indicates that genes were expressed without the interference of a disease and/or parasites,etc. How average a person's face is is associated with benefits of a healthy, parasite- and/or disease-free partner and indirect benefits of heterozygous genes that can be passed onto offspring.These traits advertise the possession of genes that are beneficial to offspring inheriting them in terms of survival or reproduction. One explanation of the importance of these facial traits is that they represent a handicap to an organism and the costs of growing the trait means that only healthy individuals can afford to produce them. Some secondary sexual characteristics are proposed to be linked to parasite resistance because the sex hormones that influence their growth, particularly testosterone, lower immunocompetence. Testosterone has been linked to the suppression of immune function in humans and can be seen in large jaw bones and distinct cheekbones.There is also a link between hormonal profile and face shape. Women with higher circulating oestrogen have more feminine faces, while men with high testosterone have more masculine faces. Reference: _URL_0_
How come sometimes (especially when I lay down to go to sleep) it feels like my heart is beating so hard (not fast) that it shakes my whole body?
I read that there's a room that isolates absolutelly every external noise, and after a while, you start hearing every single sound tour body does, and it is unbereable. The record of staying in that room was like 5 minutes.
How do we get a still picture of Earth if it is rotating at 1000 miles/hour?
short exposure time and very far away. Would you be able to tell a little blur in the clouds of earth in a photo taken from space? Not likely, not enough detail. If you take a picture of the stars with more than a few seconds of exposure, you'll certainly start to see light trails.Any space craft or satellite would also be orbiting Earth and thus moving as well. In addition, the distance make the movement less perceptible -- imagine moving something in your hand at arms length 2 ft vs. doing so across a football field and how far across your field of vision each moves.
What the big deal is with "Han shot first"
it all gave us a taste of how bad Lucas' ideas really were. Until this point most of us worshiped Lucas for the masterpieces that were the Star Wars Trilogy. When Lucas went back and started making changes, none of them were good. Most of them distracted from the films, or in the Han vs Greedo scene, changed the feel/characters. It was the first step down the slippery road that culminated with the horrible prequel films.
If the body becomes feverish to fight infection, then aren't we prolonging our illness by taking Aspirin/Ibuprofen/etc?
I'm curious about this too.. I'll often forgo that stuff if it's just a fever.. but when those stupid aches come in well
How can people tolerate large scale violence like wars, and at the same time seem revolted by small scale violence like rape or murder?
For the same reason why $5 sounds like a lot when you're dealing with candy and $50 seems like nothing when you're dealing with buying a minivan. Humans don't interpret things on an absolute scale. Everything is relative. It's all about the frame.
Why do the pimples under your nose hurt so bad to pop?
Just a sound advice about popping zits and pimples on your upper lip: # DON'T. I know they may be painful and ugly, but blood vessels from there connect directly to brain. Any infection that ends up spreading from there will end up in place you don't want, like sinuses or brain directly. It's called [Triangle of Death].
US Voting and Polling MEGATHREAD
Why do republican voters turn out and vote at such a higher rate than democratic voters? My friend said it was because all the liberals are too stoned to remember to vote. I can see that for a coupe people I know but for all of them??? There's got to be another reason.Why do congress and Senate members vote along party lines instead of with their own brains/ what people from where they represent think', "Why does it take so long for election results to come in on election night? It is my understanding the results from each precinct are immediately available and made public at that time. They are even printed and attached to the door of the polling place. Wouldn't it be pretty simple to have this data collected almost immediately?
how come my rack light on my ship (Navy) takes forever to turn on when it's dark, but if I flash my phone screen light at it it turns on immediately?
Could be photovoltaic cells that can grab some of the light from your phone to turn on quickly, but otherwise, need the ship's power to function. Find some ET3 to explain it to you if you need accurate information about her systems.
How do sports commentators (NFL, NBA, MLB) pull up random facts and stats so quick?
For football , there's normally press packs emailed to journalists with ridiculous amounts of statistics, which you would then spend a lot of time organising.Your example is interesting because that exact thing just happened. Terrance Williams #83 on the cowboys scored twice in the first half.
Why did european cultures advance far quicker than say, Native American tribes or African Tribes?
And have they really advanced? There's some accidental ethnocentrism. They both had different ways of life. Different cultures have different priorities simply put.
As a British person who has never used or had dealings with Comcast, what is so bad about them?
poor customer service, along with abysmal Internet performance during peak hours. and now you can't choose anything else because Comcast is exclusive to your area. I'm sure other people will have more elaborate stories, however I'm fresh out currently
Why are women, who are now working, still entitled to 50% of their husbands earnings when they divorce?
Let me introduce you to the weird exception: The Former Spouse's Protection Act People who retire from the military earn a pension for life. This pension is considered community property. So the ex-spouse is entitled to a share representing the percentage of the time he/she was married to the military member during their career. tl;dr: I will be paying my ex-wife appx $950/month until one of us dies. _URL_0_
Why is Shooting a Deer in the Head a Bad Shot?
A deer's brain is a target about the same size as its ear. Most of its head is its snout and jaw. Shooting an animal's face off will not kill it quickly.
Why do some substances say "Do Not Induce Vomiting"?
It burns the esophagus going down and you don't want to make that worse by having it burn again on the way up. You could restrict the breathing to the point they suffocate.When you vomit you tend to cough, coughing introduces stuff in the mouth into the lungs . Some chemicals are better off in the stomach than the lungs, lesser of 2 evils kind of thing, the stomach is better at dealing with "bad stuff" than the lungsSome substances are poisonous, meaning they are absorbed by your body and interferes with it in some way. Others are caustic, meaning they react strongly with whatever the touch. Those are the ones you typically do not want to induce vomiting with. Your stomach is one of the more caustic resistant parts of your body, and vomiting is as clean a process as swallowing, the caustic can do more damage on the return tripAcetone appears to be the main ingredient of cataclean which is harmful to surfaces in the mouth and esophagus. So, bad enough it went one way, not advisable to go the other way.
Why is the Philippine peso worth about twice as much as a Japanese Yen when the Philippines is a 3rd World country while Japan is a 1st world country?
How much your money is worth depends on two things combined: 1. The exchange rate.2. How much things cost in their native currency. The exchange rate can fluctuate fairly quickly, while the cost of things in their native currency usually just goes up slowly over time. You were assuming that everything cost the same in their native currency which is a huge fallacy. $1 might buy you a can of Coke in the US. But 1 yen will not buy you jack shit. A can of Coke will cost you at least 100 yen. So you generally want to travel somewhere when the exchange rate is good and avoid going somewhere when it's the opposite . Because prices in Japan are relatively stable when compared to the Yen, but can fluctuate depending on the exchange rate.
How can paparazzi stalk celebrities and harass them legally?
I don't know why the celebrities just don't band together, gather some money, hire some starving wanna be actors or college students and follow and stalk the paparazzis or the paparazzi's wife and kids when they go shopping at K-Mart or eat at McDonalds. Camp out in front of their house and see how they like it. Give them their own medicine, non-stop.
What's the deal with Comcast?
I'd like to add that one reason I haven't seen mentioned here, though this is definitely not the only reason. I hate Comcast because of their acquisition of one of my favorite tv channels back in the 2000s. They then merged it with G4 in such a way that it became mostly unrecognizable to its viewers. To add to this they had many cable providers remove it from their standard cable packages and add it to premium cable packages, presumably to try make more money off of this brand that they totally just shit on.
What is the deal with India and toilets? Why does such a large portion of the country either not understand their usefulness or outright shun them?
If you take a look at what a toilet really is it suddenly seems a lot less elegant. So basically you have a seat that people take turns touching their bare asses to, whatever you miss getting into the toilet you get to look forward to sitting on during your next visit. I can see why people don't bother adopting the toilet because their toilet system is almost identical to ours but where we sit they squat. tl;dr : For cleaniness.Apparently one of the main issues in India is that anything to do with feces is seen as highly unsanitary and seen as work for the lowest social caste. So the thought of being trapped with your own shit in one small room seems appalling.It's a completely foreign concept. Imagine if the rest of the world drank lukewarm tea out of old boots and you're suddenly told it's the right thing to do.
What's the difference between flat footed people and people with arches? Why is it that flat feet is a disadvantage and was at some point a reason to excused from military service?
Flat footed and military here. As /u/midwesternhousewives said, I have a lot of knee/ankle problem. Even sole doesn't fix the problem. It helps but it's not a magical solution.
How can someone learn to lucid dream?
Besides what everyone else said: *practice*. Yes, that's an excuse to take many naps! More naps = more opportunities for you to learn to recall dreams better, which leads to more opportunities to realize you're dreaming while it happens, etc. I first started to learn how to lucid dream during the summer when I was a kid and there were lots of napping opportunities. Also, not sure if it's been mentioned, but electronic devices and clocks hardly ever work properly in dreams. Flip light switches on and off in real life throughout the day and check your watch often, truly take notice of it, and if you ever wonder if you're dreaming, find a light switch or check your watch. If the light or watch don't work properly, it's a tell tale sign of a dream.
How come there hasn't been a Dexter copycat killer?
Who says there hasn't been? i mean, Dexter hasn't been caught has he? ", 'There was a guy who claimed to be inspired by Dexter and wanted to become a serial killer, but got caught after one murder. [Mark Twitchell]', "doesn't he leave no trace ??so who knows
As a pregnant woman, why should (or shouldn't) I worry about higher levels of EMF in my home?
I think it's fine. The max you're measuring is 10milligauss, correct? In comparison, the Earth's magnetic field is 250milligauss to 650milligauss. If you don't have a problem living on Earth, it shouldn't matter if you let your kid play in your backyard =). Though I would be worried about downed power lines during a storm.
Why biting fingernails/skin, or chewing lips is such a common response to anxiety, worry or fear?
I've always wondered, I used to think that it was just a bad habit.. didn't know that it relates to my anxiety.
In courts, why is admitting guilt rewarded with a more lenient punishment?
It saves resources. If they don't admit guilt then more resources and money would be spent having to find him guilty because he will not confess.Legally, you cannot be punished more severely for exercising a Constitutional Right. In this case, your right to a trial. That being said, Courts have a lot of discretion in sentencing, and there are many legal, non you-went-to-trial-so-I'll-make-you-pay, ways to bang a Defendant. Sentencing is subject to your jurisdiction's sentencing guidelines which require the Court to consider multiple factors when deciding a "fair" sentence including: an offender's dangerousness, likeliness of reoffending, prior criminal history, acceptance of responsibility, demonstration of remorse, and likelihood of rehabilitation. A guilty plea covers the last three. A finding of guilt at trial allows the Court to say "I don't feel you'll do well on Probation as you have no insight into your actions, so go to jail". Other considerations include judicial efficiency and avoiding further trauma to the victim .No, there are many different factors that can affect the severity of a sentence. Punishment is one of the goals of the penal system, but rehabilitation is another. If a criminal can come out the other side of their sentence as a reformed individual, then that's a big positive for society. A criminal who admits their guilt is taking responsibility for their actions. They're accepting that what they did was wrong and saying they're prepared to atone for it. That type of responsibility is a big positive and something that's worth recognizing.
What are house spiders doing?
Follow up question, why the fuck aren't they eating the ants in my damn house I'm letting you live rent free, eat the fucking ants.
Why does steel need to be recovered from ships sunk before the first atomic test to be radiation-free? Isn't all iron ore underground, and therefore shielded from atmospheric radiation?
There is a larger problem than the atomic bombs. One of the main ingredients in making steel commercially is recycled steel. At my workplace, as much as 25% of each Heat of steel can be recycled scrap. A large amount of radioactive steel scrap was added to the European and Asian markets post Chernobyl. This scrap was used to make steel, which in many cases has itself now been recycled. Much of the world's supply of steel is thus now mildly radioactive. In addition, some iron ore is naturally radioactive, as it shares the same ground as uranium ore. This is kept under control by testing scrap, and testing the finished product for radiation. Source: I produce radiation certificates for steel exported to Asia and Europe.
What is Pascal's Wager? and how can it be used in debate?
the idea is that you have the choice to believe in god or not, and your decision is you betting your life on whether its true. if you believe in god,if your right you get heaven and if your wrong you get nothing. if your an atheist, then if your wrong you get hell, if your wrong you get nothing from this argument the most obvious answer is that everyone should believe in god because there's no downside if your wrong, but there is if your a atheist clarification: just explaining the theory, not trying to imply it on you
