If the air and water in Rio is so deadly, why didn't the Olympic committee have it tested in the last 4 years? | The IOC invites cities to bid to host the games. The city that gives them the most money lands up being the host more often than not. Even when they aren't particularly suited to hosting the games. Rio and Beijing in particular.As others have said, the IOC doesn't care. That doesn't mean people that *do* care haven't been testing it. They have, they have been issuing warnings about how this is going to be a disaster unless Brazil steps up their water treatment game, and have been mostly ignored. For example, from 2011, "[BRAZIL: Efforts to Improve Water Quality Falling Short]", or the more hopeful "[Pollution in Rio's bay poses Olympic challenge]". If you're only hearing about it now, it's because the public didn't care enough for it to show up in major news outlets.Money like people said before but also the city has a few years to reach the 'target goals'. They discuss architecture and all problems etc, and then the city gets selected and the next few years they have to clean it up, build hotels, make it ready. --They failed. |
What does it take to run for president? (U.S.) | There's nothing legally stopping them -- but being president is a demanding, risky, and not all that rewarding job. If you want money, respect, or fame, there are better, easier, and more sure ways to get it. If you run for president, there are a large number of people who will be dedicated to digging up anything discreditable about your past and making it public. Some of it will be true and some of it will be outright lies. They will dig up school papers or letters that you don't remember reading and ask you to defend what you said decades before. Few people want to go through that. If you look at before-and-after photos of presidents, they age in that 4 or 8 year span. It's an incredibly stressful, demanding, aging job. |
what's the point of "juicing" over just eating the fruits and vegetables as is? | My understanding is that by juicing your fruits and veggies you make it is easier and quicker for your digestive system to extract and distribute the nutrients to your body. Also, when you cook vegetables the heat destroys some of those nutrients, so it is ultimately less beneficial to your body. I agree with what u/bladedada said regarding the potential downfalls of juicing. In some cases you may be consuming more sugar than anything else. I'm not a nutritionist, this is just what I've read personally on the subject. |
people eat blue cheese, which is mouldy. But why do we throw out shredded cheese that goes mouldy? | It's a different kind of mold. [Here] is a video all about food and mold. Some molds are edible, but others produce toxins that will make you sick if you eat them. |
why is it more complicated to land on mars than on the moon or titan? | One big difference between the moon and Mars is that Mars has an atmosphere. The moon has no atmosphere so you don't need a heavy heat shield or parachutes, you just land on a rocket. Mars has an atmosphere thick enough to cause heat problems on re-entry so you need the heavy heat shield, but its too thin to aerobrake or use parachutes in like you can on earth, so now you have to carry a heat shield *and* do a rocket landing Titan has an atmosphere, and its even denser than Earth's so you could land on it easily using a heat shield and parachute just like Earth. The trick with Titan is getting there. Landing on Mars requires 67% more deltaV than landing on the Moon, landing on Titan requires 2x the deltaV of Mars and 3.35x of the Moon. |
Why can't the United Nations intervene in North korea right now? | Because China and North Korea are technically allies and trade partners. If you do something to one the other is kinda obligated to help the other. If you don't help one ally then you lose street cred with all the other allies and they won't like you. So to keep china happy we let North Korea do whatever. Plus china doesn't want the flood of refugees they are almost certain to receive if N Korea gets invaded.Rule no.1 of being a lunatic and getting away without the UN fickle you over: have a friend with veto power on the UN security council1) North Korea has close ties to China, and China has nukes. 2) North Korea has a decently sized military, we have a bigger and better equipped military but it would not extremely simple. 3) North Korea has nukes, but not a good way to shoot them. They are still able to bomb some of our allies though. But the biggest reason is 1Because you would inevitably have much of South Korea destroyed in any attempt to intervene. |
What's so special about computer mainframes? | There's concerns about security in a lot of cloud applications. For example, in healthcare-related fields, there's a bunch of data security laws you have to follow and people like Amazon don't adhere to them, so you have to do your business elsewhere. Banks might have similar concerns, wanting absolute control over their data. You can also probably run your own server farm with highly specialized hardware if your product is mature enough and has performance needs outside of what the typical cloud providers can offer. Or, there's always people who work for people like AWS, or people who want to compete with them. Also, the less glamorous answer is that there's a lot of old, horrible software that they know how to run on their mainframes, but probably couldn't be ported to another system without great expense. |
Can a person move in space? If Superman could fly, would such ability work in space? | Depends how he flies. We can move spaceships in space, but if you were just floating around yourself in a spacesuit, you couldn't really do anything. |
[Chemistry] ELI5: How are chemicals mass-produced? | This is one of the fields for chemical engineers, basically a process is developed in a lab by chemists. The process is then scaled up, depending on the product different scale ups occur, most go to pilot scale then industrial scale . The feedstock depends on the final product and the synthesis path, many many products are derived from petroleum because the carbon chains are friendly to build off of, but stuff like nitrogen is literally condensed from air. Companies like Air Liquide, Air Products and Praxair do this industrial gas production. Running out of helium is possible because it's hard to synthesize, so we have to extract it from the Earth . Fusion is pretty much necessary to produce this. Read up on chemical engineering, this is what they do. |
How do antibiotics and hormones make you gain weight. | You're likely only perceiving that diet did not change - otherwise it's likely to be water weight. Fat retention doesn't significantly change without the calories to back it up. People are terrible at self-reporting calorie / food intake, and hungry people are notorious for measuring less than they actually eat. |
Why does water sometimes get stuck in your ear, and takes a while for it to suddenly drain out? | Water is actually a really weird liquid due to its polar nature. Notice how if two droplets get close enough they snap together like magnets? It's not technically magnetism, but water molecules are strongly attracted to each other. That's where surface tension comes from and it leads to all kinds of strange things that aren't possible with other liquids. Have you ever seen a close up picture of how water striders stay on top of the water? That wouldn't be possible if it was, say, rubbing alcohol. The ear thing uses the same principles. I think the best illustrative example I could use is trying to pour every last drop out of a cup. The tiny drops don't pour out easily, because they're so small that the attractive forces of water easily hold it together in a droplet. As soon as two drops get close enough, the same forces cause them to snap together, but now the drop is too big and heavy to be held together and so it runs down and out of the cup. In your ear, there's just room for one tiny drop. It's shape and the polar attraction keep it inside your ear canal, but you can easily siphon it out if it connects to a larger mass of water. |
Why is it mandatory that court judges be treated like royalty? And why isn't the President? | The customs of the judiciary date back hundreds of years . In Olde England the county and shire judges were said to 'find the law' vs. 'state/interpret the law' because law itself was believed to be derived from a higher authority . The judges were seen to act on behalf of the Crown and this is where their royal customs have been derived. The criminal law itself developed at this time, where offences with no apparent victim were seen as offences against the King himself . The regal appearance of the judiciary is important to maintain the appearance of authority, and thus authority itself. The judiciary is considered to be one of the most important branches of government and upholding that authority is vital, particularly when dealing with the executive branch such as public law or judicial review. In order to be effective the judge needs to hold authority in the courtroom to prevent disorder and contempt; this is why they dress in gowns, their bench is overlooking the courtroom, have a gavel etc. These are institutional conventions and customs, so ingrained in the institution itself that nobody really even questions it, as that is all they have known since birth. With the President, he is an elected official of the executive branch of government. He is elected by the citizens of the country and is vaguely accountable to the people- he must appear down to Earth, not royal. The U.S. is not a monarchy, and it would be odd for the country to import the conventions and customs of another monarchy artificially. However when you step back for a moment, you see that there are some aspects of royalty that do shine through: he resides in a sacred and palace-like building, he attends ceremonies, performs traditions , has a security detail protecting him at all times, relatively inaccessible to regular people, is highly esteemed domestically and internationally, access to significantly more information than most, and generally has luxurious and expensive assets at his disposal . These are a lesser form of royalty, more modern and conservative, but still effective at maintaining the hierarchy of power, and appearance of power. |
Does everybody sees the "world" equally? | Technically we don't see through our eyes. We see using our brains. The eyes are sensors that send signals to the brain and then the brain interprets the signals. The way the brain interprets the signals is influenced by past experiences and many other variables such as genetics. So there is a high probability that we all don't see the world exactly the same, but I guess we see it similar because we are able to relate to one another. I remember reading about a tribe that could see many more shades of green than the majority of people. But they couldn't see a lot of blue. Their language reflected this as well such that they had more words for the different shades of green. They also seen the sky as green and not blue. On a similar discussion topic. I always ponder about if what we see is actually what is there. Since our brains do the interpretation of the light signals coming from our eyes, do the objects we look at actually appear as they do in their true form. In philosophy there is a idea called Form I believe. Correct me if I'm wrong. It talks about this very subject. It compares it to if your whole world was shadows on a cave wall. You would pick out shapes and categorize them, give them names, tell stories about them, and mathematically explain them like how we do with physics. What we wouldn't know is the actual Form that is projecting the shadow on the cave wall. The actual form could look completely different than the shadows you see. This can be compared to the brain where the shadows are the interpretations and the actual Form is still unknown to us. |
Why do old CRT televisions emit a high-pitched ring? | A lot of electronics make high pitched noise. My [computer mouse] makes a high pitched whine any time I'm *not moving it.* Sometimes it's so noticeable that I'm just constantly moving my mouse in a circle to shut it up. I've also got a cell phone charger that whines any time it's plugged in, and several that don't.I never noticed this sound until you pointed it. Now my old CRT is dead to me!', "Does anyone have a link to an example of this? I can't seem to find one.That noise is the best way I can describe my tinnitus to people. |
why dont they make a washer and a dryer in the same machine? | I have one in my apartment. It sucks. It's so small you can only do your socks and undies or else everything comes out wet. Also a wash/dry load takes about 6 hours because it dries with steam.We had an expensive one years ago. Great washer, terrible dryer. |
Why do women's breasts in 60's, 70's and 80's seem to be so pointy compared to the natural breasts of today? | It's just the bras they used. It used to be fashionable but now it isn't. Possibly because it wasn't as comfortable as the bras of today.Their bras were pointy. It was the fashion of the day. The breasts were not physically differentBecause in 60-80s it was considered to be pretty and attractive when you "could see" where the nipples of a woman are supposed to be. A lot of women with smaller breasts didn't wear bras at all and just had a shirt/whatever on. Nowadays, it's considered to be inappropriate, "asking for it", and all bra shapes are round and squishing the nipple zone. Myself, I 've got weird looks when I wore a swimsuit without foam support that would hide the location of my nipples. TL;DR fashion is weird and bodies didn't actually change, you just don't see what's unpopularProbably not due to different bra style as some people have suggested. More likely that was the aesthetic that publishers were looking for and therefore were more likely to hire women with that lookBras underwent different manufacturing techniques over time, as it is difficult to sew or form cloth into a round shape that holds itself up. One technique was spiral stitching, hence the "pointy" lookThe answer is Lycra.Stretchable lightweight fabric that holds its shape. Supportive booby hammock instead of rigid booby torpedo. And fashion.I think you need to clarify: are you talking about how women's breasts appeared in clothing, or are you talking about how they appeared when nude? If you mean the latter, you *probably* need to mention where you've taken your sample from . |
Do women really earn only 77% as much as what men earn? | It is a very skewed statistic. It was gained by taking all the pay women make, and getting the average, and comparing it to all the pay men made, and comparing the difference. & nbsp; It doesn't take into account education, experience, or even job title. It also doesn't take into account things like maternity leave, which a lot of companies offer, and a lot of women take while most men do not take much, if any, time off when a baby is born. If a women takes off the minimum an employer has to allow her by federal law then she has lost 12 weeks of earning potential that her male counterpart did not. & nbsp; All in all this is one of the many very skewed statistics used to sensationalize a non-issue, and garner support from people that would rather blindly follow than do research on their own. Much like any statistic used in politics you should always check into them because they are usually not what they seem at face value. |
How do diners make anything you want anytime of day so fast? | Cook here. We have a very well selected menu. In terms of we have food that isn't going to take 20+ min to cook, and preparation and presentation is easy. For example; Steak and Eggs are easy to make because the longest you will wait is for a well-done steak. Also, time management. We don't cook things one at a time. We cook multiple orders at once. Ex: Ticket A is 2 hamburgers, Ticket B is a Omelette. Make room for the Burgers/Buns then make a space for the Omelette. |
What's going on in Thailand right now, and why are protestors calling for Prime Minister Shinawatra to step down? | [The BBC has a good Q & A on the subject]. I know we're not supposed to answer with links, but I think it's a good summary. EDIT: Someone suggested this [CNN link] instead. Since others suggested it was biased, I decided to also link to an Al Jazera [article] and also kind of an [interview with both sides]. |
Why we sometimes get the feeling that we're falling as we drift off to sleep. And then we flinch every freaking muscle in our bodies. | Myoclonic Jerk Sleep myoclonus occurs during the initial phases of sleep, especially at the moment of dropping off to sleep. Some forms appear to be stimulus-sensitive. Some persons with sleep myoclonus are rarely troubled by, or need treatment for, the condition. However, myoclonus may be a symptom in more complex and disturbing sleep disorders, such as restless legs syndrome, and may require treatment by a doctor. Source: _URL_1_ *p.s. it's pretty common, and not likely a problem at all.There are 4 stages of sleep. -Awake -Lightsleep -Deepsleep -REM These 3 stages cycle at a rough time of 90 mins. When you first fall asleep you are not entirely asleep, you may have vivid dreams of playing baseball. You are at the plate, just as the pitcher throws a ball you swing but your body flinches and wakes you from your light sleep. When you reach deep sleep your muscles relax and you will not flinchI read something about the brain misinterpretating something with the fluids within the ear. Does anyone knows something about it? |
Why is Northern Ireland/Belfast so proud of the Titanic? Should it not be seen as an embarrassment, saying it failed pretty badly? | Some places/people are idiots like that. I grew up in Crown Point, Indiana. What is it famous for? John Dillinger, public enemy number one at the time, escaped from their jail AND stole the Sheriff's personal car when he did it. There are signs up about it and a small museum about the man. I never understood that.Also: a lot of people worked on that ship; you could see it being constructed from the town. Everyone would have known someone who worked on it.The Irish had nothing to do with the sinking, only the building. That ship was a miracle of engineering at the time, and I've seen mock-ups and photos of it, and it looked fucking amazing. A floating palace, if you could afford it.Nothing about its sinking had to do with build quality. it was due to poor design and a shitty captain Considering that the plaque for the titanic is in a shitty hotel parking lot i dont think they are that proud |
If prostitution makes so much money, then why are prostitutes so poor? | they spend their money on drugs and alcohol. Plus they don't keep all the money they earn, their employers take more than half.Like any industry, you have people doing good for themselves, and people who aren't. Sure, your typical streetwalker at the mercy of a pimp isn't making much money, but there are self-employed "escorts" in big cites who make big bucks catering to wealthy clients. It's not unusual for a New York escort to have two apartments, one for living, and one for "work." If you know anything about real estate in New York, you'll know it takes quite a bit of income to have two pieces of property. There are any number of first and second-hand accounts of high-class sex workers that you can read about. For starters: _URL_0_watch the documentary "American Pimp" - turns out the pimp keeps 100% of the money, and just pays the prostitute's rent, basic food and bail |
What makes trains so appealing to graffiti artists? | It's all about fame within the graffiti community, the trains travel all over the city and so will be seen by all of the other artists. A lot of it also stems from the early days when graffiti exploded and the book Subway Art was released, that and a documentary movie entitled Style Wars which is about the NYC graffiti culture propelled graffiti and the train based culture into the limelight internationally, graffiti writers also get off on the adrenalin rush of tagging and piecing trains and the risks involved with it.Because trains move so often and in such large numbers its really hard to stop people from sneaking up to them and spraying paint on themI assume its because they are a mobile billboard that gets wide exposure over a large section of a metropolitan area.Because trains travel to far off places. People who do graffiti want people to see their work, it's how other taggers/graffiti artists know who they are. In a word: Marketing. |
Why is the US government bringing Americans infected with the Ebola virus back to the United States? Will that cause an Ebola outbreak here that we would be unable to stop? | They're being brought back to a hospital near the Center for Disease Control to test out new treatments for Ebola. They're being kept in isolation so there won't be any outbreaks. Actually, the CDC keeps samples of many horrible diseases contained at all times. Also, Ebola is spread through contact with bodily fluids, so it probably wouldn't spread as well here as in Africa because of better hygiene. |
what is it about boiling water that cooks pasta | I'm gonna guess it's the hot part. I tried cooking pasta once in cold water. After several unsuccessful hours I started using heat and the pasta cooked much better. 10/10 for boiling water. Would use again.If you have Netflix check out Michael Polians four part series *Cooked*. He explores elements and origins of cooking in a fascinating, cohesive manner.I don't know this to be why the noodles cook faster, but I think a lot of people are missing the difference between 99C water and steam from boiling water. 1cm^3 of water can store up to 99 calories of energy When water evaporates that value can go up to 540 calories meaning that steam contains over 5x the energy than water that is approaching boiling point. It's part of a processes called evaporative cooling where energy is released when matter changes state, cooling the water and energizing the steam. That could likely accelerate the cooking. |
Why do people still support communism and how or why is it beneficial to the country? | Communism works on the small scale, like a family unit or even clan. On the national scale, it doesn't work well. Communism takes root when people are unhappy with the system they currently live under. There are people who live in US that don't really enjoy the benefits of living in a democratic republic and capitalism. Ask a laid off factory worker in Detroit, or a person living in the Ninth Ward in New Orleans if they think the government should help them get their fair share. America has plenty of socialist programs. We aren't a pure capitalist society. There will always be people who want things more socialist then they are now, just as there are people who want things more capitalist then they are now.Let me reverse that by asking you how democracy and capitalism is good for America? Do you think it is working?More interesting question is why people still support capitalism when 99% of people has 1% of resources. |
Why do math teachers insist on tests without calculators? | They're not testing to see if you can plug numbers into a calculator. They're testing to see if you understand the logic behind the math and how it works. You can write a program to plug numbers into a calculator, you can't write a program to solve the Riemann Hypothesis or to create a Theory of Everything. |
Why does America give significant economic aid to a foreign country like Palestine to start peace talks, but lets a city like Detroit go bankrupt? | Federalism. One could spend a lifetime trying to understand its impact. Federalism is, by design, a multilayered democratic system with at times unclear divisions of authority. Simply put. Stop considering us 1 government. We are many. Local, state,federal. It isn't the role of the Federal government to run cities. The citizens and officials doomed Detroit in there every.vote. Each time an incumbent who raided the pension was reelected. Each time citizens approved borrowing vs. an increase in taxes that simply prolonged pain. Don't blame anyone but Detroit. They will survive and they will comeback, that is the beauty of our system. They lived beyond their means and the city racked up serious debt. They didn't tax correctly and played Enron math.with decades of debt. Citizens either approved, or didn't get involved which is the problem. Democracry is a contact sport and you Cant play on the sidelines. You have the be involved. In our time, with most information a click.away or a news program or book, I don't care us death to liberty. |
why is it okay for actors to impersonate police officers when filming in public locations? Are there special laws that govern filming? | They aren't doing it with the intent of deceiving the public. Even when filming in public locations the filming area is often closed off to public foot and vehicle traffic. No one is going to reasonably confuse them for a real officer. And if they did, the actors and other film crew would correct them. |
How do store's off brand products sell at half the price as the name brand product, when they each have the exact same ingredients? | One thing that most people aren't aware of, at least with food products, is that the store product is often the EXACT SAME THING, and made by the same name-brand companies. Example: Jif peanut butter. Their analysts know pretty roughly how much of their name-brand stuff that people will buy. They also know how many more people would buy it if it were cheaper by 30 cents or or whatever. So, they sell the peanut butter to the distributor at a lower price, and the distributer will put their generic store-brand name on it and resell it.Slightly off topic, I believe there is some evidence that brands are bought by people with less money than the more affluent purchasers of own/off brand goods. Showing this to be true, and exploring why, would be a good PhD. One hypothesis is higher willingness to take a chance on it not being as good because you can average spending over a longer period . Another would be more confidence in ones own choices. Interesting topic.One thing to remember is that store brands are specific to each company and not advertised, meaning all profits go back to the store. Name brand products get sold everywhere, so the profits get split into marketing/advertising, placement, etc.. And Name Brands also pay for a store to have them. That's why something like Sam's Choice Cola is less than Coca Cola .Sometimes retailers are willing to take a loss on profits to beat out the bug brands for their private label products. Typical race to the bottom. |
What happened to Malasia flight MH370? | The cyber place to go for the latest on MH370 is probably _URL_3_ . He gets into the technical aspects and much of it is really intriguing. Just a recommendation. Edit: [Here] is an article summarizing the known facts and [here] is his latest aviation post. |
Why do we often feel so much sympathy and grief over an animal we don't know being hurt or dying, but when it's a human we feel much less? | Yeah, /u/salvagebanana pretty much nailed it. Humans have a much greater capacity for . . . well, being shitty. Animals don't have the myriad of machinations and complex thoughts that humans have, so they are not nearly as capable of hateful or selfish actions. |
Why are TV shows rated so much higher than movies on IMDB? | People tend to be more lenient when rating TV shows because they take much more time to complete, whereas you can watch a movie in 1.5 hours and give it a 2/10 because you didn't really enjoy it. |
Are there any legitimate or scientifically proven benefits for men if they stop masturbating as implied by /r/nofap? (Please never explain this to an actual 5 year old) | Dave Skylark never backs down from a jerkoff, but it doesn't stop me from getting a massive case of Stankdick the same night. I dunno man, the amount of jacking off it'd take to no longer be interested in real sex confuses me, because I'm never satisfied enough by just my hand. *Though I have read about that people do get addicted to the dopamine released by the brain which makes them itch for that pleasure sensory. |
How did Wells Fargo benefit by creating 2 million bogus accounts? | Well in the long-run they clearly didn't But when you open an account, you pay certain fees on those account. Even if it's $1/month hell, even if it's 1 *cent* a month, that's $10,000,000 . That wasn't really the incentive, as such, though - Wells Fargo wasn't telling people they need to make more money. There was just a really bad culture that penalised people for not getting more accounts open, and there was no accounting/accountability.They did not directly. This was the result of bad practices within the company and a failure to identify and correct it. Wells Fargo measured their financial advisors performance on how many products they were able to sell to their clients. Every client were expected to sign on to at least two different products at each visit. If the financial advisors did not manage to meet that quota they were fired. This caused the advisors to commit identity fraud against their clients to open up accounts in their name so they would look good in the eyes of the company. It might be possible that some of these accounts will have fees either now or in the future but these small fees were not the goal of Wells Fargo. |
Why are there no realistic drawings from ancient times? | Some of its is religious cultural reasons. Some of it may be that the materials conducive to naturalistic painting faded over time or were destroyed. So, the best artwork simply couldn't survive time. Greek sculpture for example. I'm sure they had ways of planning and drawing the realism, but they used materials that didn't last. Ceramics lasted, but no one was using ceramics for naturalistic work. Remember materials were limited and very valuable. You think the Mona Lisa would survive 5000 years? Changing hands, various regimes of power, wars, revenge, fires, floods, negligence, children, lack of shelter, volcanos, earthquakes. |
What would happen if you take a compass into space? | A lot of people are talking about traditional compasses, and they're right as long as we limit ourselves to those types, but there's 2 types which are far more useful, especially if you want to bring them into space. 1- Ship compasses, which are designed to rotate freely in all directions, allowing the compass to maintain a fairly accurate bearing even in rough seas . This sort of compass would point along the strongest magnetic field in it's local area 2. Electric compasses, which function in many different ways, but generally do the same thing as type 1, just without using a free swiveling magnet. Ergo they would direct you to the strongest local magnetic attraction. One benefit of these is that they can function under much lower strengths. Therefore they could point along the suns magnetic field, or even the galactic field if you took them out of the solar system |
How is my credit score arrived at? Why does canceling a credit card negatively effect my credit? | many different factors. the major ones are: 1) length of credit history2) history of ontime/late payments3) how much outstanding credit you have vs how much available credit you have. this is called credit utilization ratio. when you have $1000 outstanding balance on a $5000 credit limit card and $0 on another $5000 limit card . your credit utilization is 10%. if you were to cancel the $0 balance card, you now have a $1000 balance on $5000 worth of credit, 20% utilization. u need to keep the utilization as low as possible. don't exceed 30% |
How did the Nordic countries convince their citizens to pay such high taxes? | The governments of said countries don't convince the people to pay more taxes - *the people tell the government* through voting that they want to pay high taxes in order to receive said services. |
Why is it that the more annoying the tune, the harder it is to get it out of your head? | If a tune is catchy, but you like it, it isn't a problem so you never get annoyed by it.If a tune isn't catchy, it won't stick. The only tunes that will stick in your head are the catchy ones that you don't like. |
What potential is lost when the U.S. doesn't adhere to the metric system? | They probably won't make the switch over night. They will probably start teaching metric in schools and new roadsigns will probably have metric and imperial on it. The imperial system will die a very slow death. |
Due to the extra chromosome, do people with Down Syndrome only accept blood from other people with Down Syndrome? | In addition to what other people in the thread have posted, it's also worth noting that red blood cells don't have a nucleus and therefore don't have any DNA. There's nowhere for that extra chromosome to hang out. The only thing that matters are the special proteins on the cells' surface that determine the blood type. And as it turns out, the extra chromosome doesn't change how the bone marrow builds the blood cells. |
Why men must have a urinal in between them while urinating. | If we don't leave a urinal in between, somebody might try to sneak a peek!", 'Some people are socially awkward like me and are just more comfortable with it like thatIt's one of the dumbest attitudes about something there is. As I said in another post this week about guys being awkward about being close to each other: Try living for 6 or 8 months on a tour bus with 11 other guys. You get more ball-sacks in your face than Jeff Stryker. We were on tour with Hall and Oats one time, I'm the only one in the bathroom and G.E. Smith comes in and stands at the urinal next to me. I looked over at him and said: "Hey, how come you get a pink laminate and I get a yellow one?" "Because I'm gay, and you're not." He's not gay, just confident and funny. Real men don't worry about stupid shit like thisAnother reason would be splash zone. No one wants someone elses pee on them. Well, usually anyways. Also, if a line forms, people usually start using the empty urinals. |
Why do major cell phone carriers allow companies like MetroPCS, Cricket Wireless, Boost Mobile, etc. to resell their network? | carrier networks are fixed cost. If they're not running at 100% capacity they're losing potential money. So they'll often rent part of that capacity to other companies in exchange for a guaranteed income. They'll make more profit off that contract then they'll lose from customers switching |
Why do all of my electronics have an FCC interference statement? | Tile 47 CFR part 15 states that any device that emits radio waves, intentionally or not, must be licensed unless it qualifies for an exemption. The most common exemption is for unintentional emitters. So long as a device's transmissions are below a certain power level and transmissions of a certain power level do not interfere with the device, they do not require a license. Such device must be evaluated before they can claim to comply, and the message you reference is a statement of that compliance. From a consumer's point of very, if a device has that statement, you can use it as much as you like and not be concerned about any sort of license. If the device winds up causing interference, that is on the manufacturer. If a device does not have that statement, then the onus is on the consumer to make sure they comply with licensing regulations. |
The Five-Year-Old's Guide to the Galaxy | Has anyone tested these with an actual 5-year-old? I'd be interested in seeing how it goes. I'd try it myself but I don't have any 5-year-olds available currently.I really enjoyed this: _URL_4_ and this: _URL_5_', "I read The_Cleric's debt ceiling answer, and I have to say, that was an excellent, non-political explanation. :) |
Why is it I could stomach the sight and smell of everything in my 20s, but as I approach 40, everything makes me gag? | This is a wild guess, but could it have to do with our immune system weakening as we age? We have gag reflexes to prevent us from from ingesting things that might be bad for us. If you're young and you accidentally eat poop, it's easier for your body to recover. But if you're old and get some sort of a disease as a result, it takes a greater toll on you. So to compensate, your body ups the gag reflexes to make sure you don't accidentally eat any poop after you turn 40.Increased estrogen is associated with an increased sense of smell . Are you on hormonal contraception? Some medications can also cause it. What medications do you take?', "Haven't seen this mentioned. There certainly are physiological and psychological changes involved. As you age, everything changes in your body. The changes I've noticed are: I crave sugary foods or candy way less than a decade or so ago. I used to love chocolate, and nowadays the thought of eating it is sometimes a bit repulsive. I would rather have something salty for a snack. Things I couldn't stand before, like strawberries added to a tomato, lettuce and cucumber salad, are now quite tasty. This includes many other sweet-salty mixtures like some oriental sauces. Speaking of the psychological aspect of it and why you've become more sensitive to those things in particular, well that would require knowing a hell of a lot more about who you are, which makes it impossible for me to provide any insight. |
What's the difference between semiconductors and normal conductors and why are they preferred in electronics? | Electricity is the flow of electrons, so the conducting properties of a material depend on whether the electrons in that material are free to move. In a conductor, the electrons are not attached to their parent atom. You simply have a bunch of atoms in a 'sea of electrons' and all those electrons are free to respond to any applied voltage. In a cold semi-conductor, the electrons are bound to their parent atom and cannot move, so the semi-conductor acts as an insulator. However, when the material is heated up, some of these electrons gain enough energy to escape their parent atoms. These electrons can now move freely, and the conductance of the material increases. The hotter the material, the more electrons will escape from their parent atom, and the conductance will improve. |
How do piratebay uploaders like YIFY,FLT, Skidrow and others make their money? | Since it hasn't been mention yet, many do it out of conviction. Not everyone believes in intellectual property. |
Can my red be your blue? | In a sense, it is possible, but we can't know another person's experience. So we will maybe never know for sure.Red is quite a hot colour, whereas blue is quite cold |
If our genes mutate all the time, why is cancer so much more common than a good mutating? | A single cell that mutates so that it metabolizes slightly more efficiently for example isn't going to mean much. It will live out its normal span and then die like the rest, never imparting its features to the organism as a whole. Cancer on the other hand is defined by its tendency to grow endlessly and become a macroscopic part of the organism. Growing uncontrollably is what makes it significant and yet also what makes it dangerous, so such bad mutations are by their very nature going to be more commonly encountered as emergent mutations. |
Why is it okay to mock Christianity but not politically correct to mock Islam? | [Extremists] Nope, the biggest influence to ban islam mockery is found in [politics]. Most politicians want to appeal as broad as possible, and at least in the EU, want to appeal to the brotherhood of 'everyone', which means nobody is condemned. Also Saudi arabia, although I don't think they give a shit. |
When the Baby Boomer generation retires will the removal of all their retirement investments have an impact on the economy/stock market? | It shouldn't have a huge effect. - Markets react negatively to *unexpected* news. We've known for some time now exactly when Boomers would retire. - About 10% of Boomers hold 90% of the wealth of the generation. Obviously, the wealthy will not have to cash out their investments like the typical retiree. - Foreign investments will help take up the slack. - The total share of investments by Boomers is no different from any other group of 46 to 64 year olds in the past. |
Do birds ever fly for fun? | I was paddling out on the lake by my house in NC one time and saw several Osprey flying just above the water and skimming their talons along the surface. Then they would gain a little altitude and haul ass back down and repeat it. IMO, they were having a blast. I've seen them hunt for fish and usually they are pretty high until they spot their prey, tuck their wings in, and dive straight down at high speed to snatch their fish. They look like Stuka dive bombers, except their descent angle is much steeper. Maybe I'm wrong, but when I saw them skimming they just looked like they were enjoying life. |
Why the heck did Dr. Frankie kill Eddie in Rocky Horror Picture Show? Oh, and what is the plot exactly about? | While the plot is largely irrelevant at this point , here is a very brief synopsis. Two newly-engaged lovers get stranded at a castle. The inhabitants of the castle include transexuals, one of whom has discovered the way to create life. After he demonstrates this ability, all of the inhabitants engage in various sexual shenanigans, until the true nature of the castle's inhabitants is revealed. |
How do we know voter fraud does not occur in the U.S.? Is it possible that it occurs undetected? What evidence should voter fraud theoretically leave behind? | There is a mathematical method known as Zipf's Law that is very good at detecting things like voting fraud. I would expect that US elections are scrutinised by many analysts who would be using this Law to detect irregularities. I have tried searching for a ELI5 friendly explanation of this in more detail but all the pages I could see were at an academic level of discussion. |
Why instant noodles are not good to our health? | It's not the sodium. I don't think instant noodles are an ideal food source, they are low in fiber and other nutrients and replace whole plant based food in your diet. However, there is almost no evidence that sodium intake is harmful to human health. There is even some evidence showing sodium restriction can increase mortality rates in the general population. In fact, one of the healthiest societies in the world consumes levels of sodium many times greater than the much in healthier US. We gotta stop hating on sodium and focus on things that can actually make a difference! |
Why wasn't the Bill of Rights included in the original Constitution? | There was a common school of thought that it wasn't necessary. For example, if the Constitution didn't give the government the power to restrict your freedom of religion, then you didn't need a specific guarantee of it because the government couldn't do it in the first place. This argument wasn't as persuasive among many groups as the people making them had hoped, so the Bill of Rights came shortly afterward. |
with websites like Expedia, and the ease of access to the internet, what exactly do travel agents do nowadays? | If something goes wrong, you've got a person to call who will do cartwheels to make it right for you. Any and all of it. |
How do parkour jumpers land such high jumps without getting hurt? | They have certain techniques that doesn't put as much stress and force on the parts of the body that may not be able to handle the fall. _URL_1_", 'Landing from high up usually involves rolling out of it in Parkour. What this does is extend the length of time and spreads out the distance you have to slow yourself down. Because you take longer to slow down, the force that is put on your body is less. The roll also allows you to redirect your fall essentially. Instead of having to use all of your strength to make you stop moving, you can use less of it to turn a falling motion into forward motion. Thus putting less strain on your bodyIf you watch them when they land they usually do a roll. They are using the forward momentum to transfer the energy. If you just jump straight down all that energy is going straight to your knees and ankles.I'm surprised no one mentionned this : protection pads used by stunt men. Source : _URL_2_ |
How does a company having expensive lawyers make them impossible to sue? The law is the law, right? | *Spits out water.* HAHAHAHAHA. This is America. Money is power, and power is above the law. There was a guy so rich he basically *murdered people for fun* and didn't get caught until he let the cat out of the bag on HBO.> The law is the law, right? Think about it. If it was as simple as that, why would there even be lawyers?', "the ELI5 explanation: Imagine you're playing a board game, the rules are the rules - but some are open to interpretation. Let's take the Monopoly free parking rule. This isn't in the rulebook of course, it's just something people made up. You land on the space but your older brother screws you out of the payment. You bring it to your mom to settle. Your older brother has 20 of his friends to help him explain to mom how free parking is stupid, and isn't a real rule, and you never actually 'said' you were playing with it. You just have your friend Joey. Joey tells your mom you've always played with free parking before and when your older brother landed on it, you never complained. Ultimately it's up to mom to judge. But while mom's trying to judge your older brother's buddies are coming up with a zillion ways to discredit the 'Free Parking' rule. You just have Joey.. Joey's a good guy but he has to go home in an hour. |
Why do cultures who rely heavily on rice in their diet typically use white rice which has less nutritional value than other types of rice? | Chinese from Singapore here.Honestly, like what some of the comments here have stated, brown rice just tastes weird. It's bitter and feels like you're eating nuts but well, you're not. Perhaps it is due to cultural conditioning, but to me, it doesn't go well with the Chinese dishes. It doesn't have the slight sweetness white rice have after it is cooked nor does it mix well with the dishes. |
Why can't prostitutes in the US just call themselves "Freelance Porn Actresses" and just have a camera on them? | Why can't it just be legal to sell sex? Then we can protect everyone.Because people dont wanna be filmed while going to a prostitute', "I don't really get the whole illegalizing prostitution thing, we had to a research audio-log thing on something for school at one point and for whatever reason my teacher let me argue why prostitution should be legal, my parents weren't quite sure how to react to someone. |
Why is it "bad" to make tea in the microwave vs a kettle? | Microwaves don't heat evenly, and hence there are several possible results, none perfect: cold spots in the water, superheated water that boils vigorously on contact with the tea, or water that's been heated long enough in the microwave to come to a rolling boil, at which point there's a good chance that the oxygen has been boiled out. All of these can affect the flavor of the tea. Most people who are into tea agree that most black teas should be seeped with water at 212°F. A tea kettle or hot pot, whether electric or stovetop, heats from the bottom, creating convection currents that stir the water, allowing the temperature to be uniform. Plus it's easier to know exactly when the water reaches the desired temperature. [Partial source] At the risk of being a tea snob, if you're adding a tea bag to a cup into which you've poured hot water, you're already compounding the problem. The water will cool off from the cup, so when you add the bag, you're dealing with water that's already colder than it should be. Whenever I use bagged tea , I always put the bag in first and then pour the water onto it. |
Why do i wake up "angry?" | If you're a teenager you should try and find an Australian documentary called Whatever. It's about youth - there is an episode on sleep. It may also help if you're in your young 20's. If you have troubles finding the doc, I'll upload it or something for you. |
If millionaires and billionaires don't have an income and bank account(s) the same way ordinary workers have them, how do they exactly collect and spend money? | If you're asking how they actually pay for things, wealthy people still have cash in bank accounts and credit cards. If you're asking how they make money without working, investments increase in value, and some pay income such as dividends from stocks. If I have 100 shares @ $10 than 100 shares at $15 in 5 years, I can sell off some shares and still have the same value. Historically you could make close to if not more than 10% a year, in the past 10 years though the average annual return is only 1% due to all the crap that happened, so you needed a LOT of money over the past 10 years to be making anything safely. |
Why can sad music make people happier? | Personally for me it gives me the feeling that someone else is sharing my struggle and that I'm not alone. I guess that's anecdotal and I'm not sure of the science behind it but that's what it is for me. |
Why is bacon sold in strips and not big ol' delicious hunks o' bacon steaks | You can get there with pork bellies. Or if you're cheap, buy the bags of bacon scraps/ends. Mileage may vary, but I've gotten some really nice, fat hunks of bacon. Soooooo good. Skinny bacon is a waste of everyone's time. |
Why are corporations, especially the larger ones already worth billions, always so concerned with growth? | It's basically a fight for consumers and you want to be the one who wins the fight. Not growing as much might not be a horrible thing for the company right away but if a competitor grows faster you'll sooner or later lose your customers and the company will stop producing cash. And for big companies that's all people want, cash! And you go with the companies that give you the most, it's simple and barbaric. There are a few companies where it isn't as important, usually niche products and smaller family owned companies with very specific customers. But the textbook lifespan of a company is a growth phase, where you make tons of money after that the growth slows down and finally there's a stagnation. There are some very big companies that are at that point and stay at that point through very good marketing, but for most companies what follows is shrinking. And even though you might stay profitable for a while you'll most like end up selling parts of the company firing employees and at some point there's nothing left. TL;DR A slow down in growth is a indication for the company and the market to shrink and a sign for investors and share holders to leave the sinking ship. |
How do they prevent you from bleeding out when they cut you open for surgery? | Surgery is very complex, lots of things are going on at once. But one thing that prevent patients from bleeding out is to avoid any major arteries or delicate structures in the first place. Some common surgery mishaps are beaten into your mind in med school no matter if you will become a surgeon or not . Also if you're low on platelets they will also load you up, most surgeons won't operate if it under 100k. |
What should i do if i find myself in the attack range of a venomous snake? | Snakes feel your vibrations through the ground so standing still and seeing if it passes is best. If not slowly and gently back away. When we enter thick grassland/dense bush we are taught to walk heavily to let the snakes know we are coming and so they move before you get there. This is because accidentally stepping on a surprised snake that didn't know you were coming is the greatest risk of getting bitten well apart from trying to pick it up when drunk :) Source: Australian.Stomp your feet as you walk to drive them away. Avoid tall grass and rocky outcrops. If you see one back away slowly. They want to avoid you as much as you want to avoid them so giving them a heads up with the stomps is the best route.I came across a timber rattle snake in upstate New York of all places. As you might imagine, I was not exactly expecting this. It rattled. I freaked out, turned, and ran. It was probably about two feet from me to the side of the path I was on. It didn't bite me. Might have just been lazy or something, but I jumped back immediately. |
Why does all my body fat go on my stomach? | My doctor had told me that the fact that my weight gain was mostly to be stomach was something to with Cortisol - I was told that this is the hormone that's released more in times of stress although there wasn't much in the way of further explanation beyond that. |
Why do we tip bar men and women in America 1 dollar per drink? Doesn't this mean they would earn well over 100 dollars per hour in a busy bar? | Unless people are ordering a million shots, it's very difficult and stressful to serve 100 drinks in an hour. There's probably no bar in the country where more than 75% of the patrons will tip appropriately. And even the hottest bars are only really *busy* for 3 or 4 hours a night. So a very good bartender, at a popular upscale nightclub, will end up earning $50-60 an hour. That's certainly good money, but it's not clearly unreasonable. |
Why is America so poor at maintaining its infrastructure compared to other developed nations? | We developed modern Infrastructure systems far earlier than most of the world, and it worked so well for so long that we have become set in our ways, not not been thinking about it. We have basically the same rail system form the late 1800s, and the same road system since the 1950's. Since then, it has mostly been the world trying to catch up to us, and we were a bit late or realize we weren't investing enough in new transportation. |
If polls say America is leaning towards marijuana legalization, why do states keep failing to pass reformed legislation? | Well here in Florida we have this stupid law about constitutional amendments where they need a 60% majority to pass . Our last vote on medical legalization failed to pass with a 58% yes vote so I don't see it happening anytime soon here. |
Why can't we just "make" water? | We can, but it'd be rather hard, terribly expensive and not pay off at all.Like you’re five: If you’re out of cookies, why can’t you make more? To make cookies, you need cookie dough and chocolate chips , but there are ~~none~~ *no chocolate chips* in the pantry . e: Okay, we have a lot of cookie dough, but we’re still out of chipsThat would work perfectly well, except that there is no hydrogen gas in the atmosphere. There are plenty of hydrogen atoms inside molecules in the environment, but it would take energy to split the molecule to get the hydrogen out. In basically every real-world situation, it is easier to just find water that already existsEven Tattoine had moisture vaporators on it. No air is ever completely dry, not even in the Sahara. If you had energy to waste, you collect water from the air, even in the Sahara, by refrigerating a surface and collecting the condensationFYI, every time you burn gasoline or metabolize food, you "make" H20 When you want hydrogen, you take it from water. you rarely find it on its ownOn a similar note, how hard is to make ocean water drinkable? |
What compels me to remain stopped for police? | If you are pulled over by the police, what compels you to remain stopped is the law. > Lacking announcement of officers legal status You can ask to see a badge. If in doubt, you can call 911. > Lacking indication of probable cause for detainment/search/seizure You are not qualified to make that determination. That's what we have judges for. If the officer is in error, and there was no probable cause, then your remedy is in court, not in the shoulder of the road. > Lacking lawful declaration of warrant issued by a elected judged of the people. He doesn't need a warrant to pull you over. Anyone who tells you otherwise is an idiot. > Upon exiting the emergency vehicle, individual is clearly lethally armed insighting fear for life/limb/safety Well, yes, of course he is. The fear is your problem to conquer.Generally, if you are being stopped by a police officer, its for some reason akin to speeding, reckless driving or some other reason. In that case, you pull over, the officer speaks to you, and if its a misunderstanding, he lets you on your way. Otherwise, if you are being pulled over because he is going to issue you a ticket, and you take off racing away its called Evading police and Evading arrest, obstruction of justice, and can easily escalate to reckless and dangerous driving, further speeding charges, assault, battery, assault with a motor vehicle, and so on When you are pulled over, just sit there and behave. You are on the road because you agreed to the terms and conditions of having a drivers license. **Dont like it? Then dont drive.** Thats the goverments logic on the situation. |
why Shakespeare is so great? What sets him apart from other great writers, either from his own time or after? | You know all of those cliches in movies and plays that you hate because they are done so often? He's the one who came up with most of them and made them his own. Most modern literary allusions boil down to Shakespeare, the Bible, or ancient mythology. |
Why primary education is disproportionately a female institution? | This might be somewhat off topic but I work somewhat with nurses by delivering them their patient's medication. It is surprising how many men are nurses. |
In the past, how did humans survive without clean drinking water? | Get the best you can. Water from a swift-flowing stream or from a well is usually safe to drink. EDIT: Or from a spring, where water flows from a source in the ground, which can be so safe that nowadays it's bottled up and transported as 'mineral water' with minimal further treatment. Boiling it will make it safer. And then you can take advantage by using the boiled water to make tea or coffee. Turning it into an alcoholic drink can also make it safer. And of course people did get sick. While there was a vague understanding that clean water good, dirty water bad, people didn't know much about disease. Sewers got built because people believed foul smells caused sickness. In the industrial age cholera pandemics repeatedly swept the world killing hundreds of thousands. Fortunately, for many diseases those who do survive them once are then immune for decades after or even for life. |
Space X landing the first stage of a rocket back on the ground | how far out in space did spaceX'es falcon9-r reach? and why is it a massive achivement for us?", 'How much of that ~$50 million will be spend repairing and prepping the stage 1 to be reused?ELI5: Why could Space X not use drogue shoots to help slow their rocket for landing?', "SpaceX's last rocket blew up, but this one didn't. What changed? |
Why do we shut our eyes and scrunch our faces right before we are hit? | Your body is reflexively tenses up to create a harder surface against an impact. The eye closing is your body's attempt to protect your eyes. |
what is it about electricity that makes it so dangerous to the human body? | I think one of the most critical things that I didn't read in the top comments is that amperage kills you not voltage. It only takes 5 milliamps of current to kill you so .05 amps, well let me tell ya your toaster uses somewhere around 15ish amps. So think about that next time, your cell phone charger isn't enough to cause an arc or an explosion in most cases but you send that current through someone's heart they dead. Think of electricity as a water hose, the voltage would be the water pressure and the amperage would be the volume. So you touch an outlet and that's 20 amps through your body that's 400 times the amount of current that could kill you |
Why does cold weather make your nose run? | You haven't experienced cold until it makes your nose hair freeze and stick to the walls of your nose.So I saw this perfect explanation on another reddit thread about half an hour ago. "A king has a son with two penises. When it comes time for the boy to marry, they search for a girl with two vulvas. Such a girl is never found. The prince dies without having married and becomes a ghost, searching for a girl with two vulvas. Eventually the ghost turns his sexual attention to people's nostrils. From that point on, people begin to catch colds. When the ghost’s penises enters somebody's nostrils, that person's nose feels stuffed. When the ghost is satisfied, he withdraws. The person can breathe again, but as the ghost has left his semen, the nose runs.Cold-induced rhinorrhea" is what you're describing, and it is thought to be caused by two things. Cold weather dries out the nasal passages, to offset this more mucous is produced by tissues lining these passages. Also, water vapor in warm exhaled air condenses as it meets cold outside air.When temperature comes below 8-10°c, the natural fluid movement in your nose does not go to your throat but is reversed. . Here's a [quite good podcast] explaining it.** |
Why do hostages of IS agree to say what they captors want them to say? Knowing they're going to die anyway, why wouldn't just refuse to give in? | I can tell you you'll be killed in one hour. Then say, you're going to say what I tell you say OR for the last hour of your life a blow torch will be held to your genitals. You'll say whatever you're told.> "It's not like they're gonna torture you or anything" Unfortunately, they will. They're not going to give someone who argues against them or refuses to play along the quick death. I remember reading in an article when James Foley was killed that they had put him in that situation more than once, and he may not have initially realized that the last time was THE last time. But if he 'd argued or gone against them, he probably would have been dead a lot sooner. You play along and do what you can to try and improve your chances of making it out alive, or just prolong death as long as possible. |
Why do cats enjoy being stroked so much? | Cats have over and undercoatings of fur and when they are wet it is probably just really uncomfortable. That said, some cats actually do enjoy going for a swim. Cats have really sensitive pads on their feet and it probably bothers them. An animals stomach is their most vulnerable spot where all of their soft organs are, most are instinctually prone to protect their tummy. That's how you know a cat or dog is truly happy and trusts you - they roll over on their back. |
Why do we use salt when cooking fish, since they have been marinating in what is essentially brine for all their lives? | If you wear rubber gloves and dip your hands in vanilla extract, and then take the gloves off and lick your fingers, you don't taste Vanilla extract. You're eating the meat not the scales. IANAE", 'A survival trick that sailors use when they are short on fresh water at sea is to catch a fish and squeeze the juices out of the flesh. Although the fish lives in undrinkable salt water it filters out enough salt internally that you can stay alive by drinking it. |
Why are men sexually attracted to the female butt even though it serves no reproductive purpose? | I was thinking about this the other day. By looking at a girl's butt you can measure her physical fitness. |
Why does black absorb more heat than white? | Wrong way round. Black objects don't absorbe heat because they are black. They appear black because they absorb nearly all light, and therefore heat, that reaches them. Objects appear white because they reflect nearly all light, and therefore heat, that reaches them. |
Why College Football schools needs that large stadiums (90k+ attendance)? | Because each of those games brings in a ridiculous amount of money, and there aren't very many costs associated with the stadiums when they're not in use. They're mostly outdoors, so electricity usage is pretty low, and it's not like they have to pay the staff year-round. |
What are the actual anatomical and physiological differences between the races? | You might find this interesting, I know Asian people are far more prone to it. It's on the physiological side of things.[Alcohol Flush Reaction] |
Why are fluorescent colors special and why did they not seem to exist before the 80's? | Check out the story of Fluoroscein _URL_0_ My understanding is fluroescence occurs when molecules/atoms absorb higher electromagnetic energy and release it at a lower wavelength ", 'hahahaha didn’t exist before the 80s?!oh you kid |
Why do cups with lids have to have two holes in the lid to work properly? | As liquid leaves the cup, air has to enter to take its place. If air doesn't replace the liquid, the pressure in the cup will drop more and more until the liquid can't pour out anymore. With a single opening that results in the glug-glug-glug effect as you pour, when the pressure inside drops enough that air gets sucked into the container though the same opening that you're pouring out of. But with a separate opening for air to enter, the pouring is smooth. |
The whole Matrix Story line | For the whole Matrix story line you also need to know about the Second Renaissance, the prequel to the trilogy. During the mid-21st century, when AI did all of human bidding, a servant robot called B1-66ER murdered his master. B1-66ER was put on trial and testified that he heard his owner saying B1-66ER was to be scrapped, thus he killed his master out of self-defense saying he simply did not want to die. The jury/judge ruled in favor of the deceased. B1-66ER and all of his kind were to be decommissioned, resulting in a genocide of AI. Eventually, the AI took refuge in their own city called 01, located in *The Fertile Crescent*. 01 sent ambassadors to the U.N. where they offered to work alongside mankind, however they were not accepted into the U.N. Subsequently, 01 sought to rival humans in production; easily outpacing and out qualifying humans. 01's currency rose and human currencies fell, threatening human existence in the wake of 01's success. Thus, the humans waged a war against the AI. A main point in the war: humans decided to cut off the AI from solar power by blackening the sky. But once the humans lost the war, the AI sought to use human bioenergy as a power source. AI built fields of pods where humans could be stored and their energy harvested. The Matrix was created to control the minds of those humans in these fields. The symbiotic relationship that grew from this is the essence of the Second Renaissance and sets up the events of the trilogy, which the other comments do a sufficient job describing.Reality is a simulation to trick the humans, who are actually being harnessed to power evil robots. A chosen one is found who can free the humans and fight the robots. The war is fought both inside the simulation and out. |
If child pornography possession is illegal, why hasn't Snap Inc's CEO gotten arrested? | It may not be written in the law, but I am certain there is a precedent of sorts that differentiates between private ownership and third party ownership. For example, if you keep stuff in a storage locker, the storage company becomes a third party owner. If you kept your locker full of illegal material, the owner of the company would not get in trouble. The same can apply with bank safety deposit boxes, the postal office, or any other institute that that holds someone else's possessions. |
Why do people who have been sentenced to death have to wait years, sometimes even decades, for their execution to take place? | Endless appeals. The government tries to be very careful about who they put to death. It's actually more expensive to sentence someone to the death penalty than it is to imprison them for the rest of their lives. Personally, I don't give two fucks about these peoples lives, but I'm anti-death penalty because of the money wasted on it.There are a lot of automatic appeals built into the system - both state and federal. Each one can take years. |
Why are our planets in the solar system all on the same disc/plane/layer? | Think of the Sun's equator as your waist and the plane the planets travel in as the hula hoop. As somebody else noted, they don't all travel perfectly in this plane but then you can have two or more hula hoops right? |
- Why don't car makers sell directly instead of using dealerships? | As others have said, many states make it illegal. The motivation is that they want to encourage competition at the retail level, both for sales and for repairs. Tesla, which wants to sell direct, has been fighting this battle in a number of states. They've won a lawsuit in Mass, gotten New Jersey to change the law, but failed to change the law in Utah, and are still negotiating with other states. |
Why is there so much USA currency (quarters/nickels/dimes) circulating in Canada and can it be exchanged at a bank for Canadian change with the exchange rate? Why or why not? | Here is the actual answer. You *cannot* exchange USD coins at Canadian financial institutions. The reason, most likely, is because it is expensive to handle, process, ship and be compliant with coins. And I'm talking now about CAD coins, imagine adding USD coins on top of that? Forget it, the banks would be paying big bucks to handle USD coins. Paper bills are the only accepted USD currency at Canadian financial institutions. Intria and Symcor do not handle or process USD coins. If you have a lot of USD coins, make sure to spend it next down you go to the states and make sure you never comeback with any. |
