In hindsight, with everything going on since the early 21st century, what is the difference between the world's military affairs versus World War III? | One of the major differences between now and WW2 is that WW2 was total war - much of our industry was devoted to producing materiel for the war.The biggest country-to-country war going on right now- and you have to compromise your definitions to make it fit- is Russia vs Ukraine. In terms of world involvement, that's n... |
How does post-partum depression happen? | During pregnancy, there's a lot of hormonal shifts that the mother goes through. In particular, there's a lot of bonding hormones and feel-good neurotransmitters that get shuffled around.

Why are the arts considered inferior to sciences? (serious) | Maybe it is a product of the times we live in. People today desire practical approaches to life and rely on numbers and hard facts to shape their thinking. Perhaps the stigma of starving artists or musicians has been further propagated by the rise in college tuition while salaries remain meh. Thus people value those wi... |
Why do people get sick more often in the winter months? | Less sunlight and less warmth makes people to spend more time inside. Being inside together makes it easier for microbes to spread by contact or air. When they do happen to be out, the cold weather makes their nose run these microbes can get on a sleeve or hand and travel farFor humans, cold is an immune system debuff ... |
Why does my cat lick things uncontrollably when I pet him? | I reckon it's an instinct. You draw your hand over it's fur and making it smooth, just like it would do while licking itself. Dogs that move their foot while being scratched, I think do the same thing-they are scratched so they start doing the move. Could be entirely wrong. |
How can people reasonably say Jay-Z is in the Illuminati? | No one "reasonably" says Jay-Z is in the Illuminati. That's about as unreasonable a thing to say as is possible sober**Short answer:** You're talking to idiots. Stop it. **Long Answer:** Some rappers have recently been making references to the illuminati. Their fans, who have never actually heard of the illuminati befo... |
Why cant cats be trained? | Cats can definitely be trained. My cat was trained to sit, lie down, beg, fetch, etc. I had a puppy at the same time the kitten arrives, and they just learnt together. I used the same techniques as I did on the dog. Using treats as an encouragement, never punishing or hitting.[This lady taught her cat to eat with a for... |
Why do schools always assign dystopian novels as required reading for English classes? | Why not? It's a fairly expansive genre, and books like *1984*, *Brave New World*, and *Atlas Shrugged* are some of the most widely referenced works in today's culture. Not only that, but they are fairly encompassing when it comes to human nature and society. There are fairly grand statements being made by most dystopia... |

How is a Google search so quick? | Also, though you may find it hard to believe, almost every search you can think of has already been searched for by someone somewhere. For vast numbers of these common searches, search providers like Google already have the answers stored in a cache. Obviously they updated it from time to time, more often if it's a fas... |
Grand Final/Superbowl halftime... everyone seizes opportunity to use restroom. Does the local treatment plant receive a tsunami? | Not a Tsunami, but they definitely use a lot more water. I think the best example of this was the USA vs Canada Gold Medal game back in 2010. Since there are less stoppages during a game of hockey than there are in football or other sports, the water usage was increased tremendously. Heres a graph. _URL_0_ |
How does companies like Whatsapp, Viber and Handsent work? I can send/receive messages for free using their services, while phone carriers charge so much. | Saying 'it is free with the apps' is a bit of a incorrect statement. The apps use your data to send the messages unless you are on wifi. The messages don't increment the text counter that normal text messages use to know if you are nearing your limit . So you still pay for it just under your data plan, and not the text... |
How do optometrist know what dioptre toddlers need, if they can't give feedback on the glasses? | There are tests that see how the eye focuses automatically. One of them uses an image [in my case it was a hot air balloon] and your eye will naturally try to focus on it. The machine bounces a laser off your eye and measures the defraction to see how the lens changes shape. This is used to get your correction fairly a... |
What are those random sharp pains I get often on my skin almost like a big bite that catches my attention but immediately goes away? | It could be a misfire of the nerves. It could be a hair stuck and being pulled on by something. Or it could be an insect, there are many microscopic insects that live in the pores and hair follicles of your skinOne of your hairs likely got caught in the fabric of your clothes and got tugged. When you reach to scratch i... |
Why a chef wears white, and why the tall hat stereotype exists. | White is a clean color. Chefs will know if food has stained their clothing because they can see it against white fabric, which is really important to prevent food poisoning and cross contamination. White clothes can be bleached. White fabric also repels more heat as compared to other colors, and kitchens get very hot. ... |
How are fingerprints left behind when, according to the chemistry of molecular bonds, no two surfaces TRULY touch as the bonds repel one another? | saying that the surfaces don't truly touch is an interesting philosophical observation about the meaning of "touch" but doesn't really impact your question. What we call "touching" at the macro level is an interaction between atoms that prevents them from occupying the same space at the same time. That this can have ef... |
If the existence of Jesus can’t be proven/isn’t widely accepted in the scientific community, why do we still use BC (Before Christ) to measure time? | At this point, because it would be too difficult to switch off, and there would be no benefit to doing so. All our records are essentially written in AD/BC formats. Due to globalisation, even cultures who aren't Christian will use the AD/BC calendar date. Many have switched to the CE/BCE naming style to avoid religious... |
How come if you have a glass of water with ice, when you turn the glass, the ice stays in its place? | Inertia. A body at rest will stay at rest unless acted upon by an outside force. Not only the ice, but the water within the glass has mass and thus inertia. The only force being conducted to it is the torque applied through the low friction walls of the glass--very little. |

Why do people tend to look up while there trying to remember something? | In the 70's a psychologist named Paul Bakan proposed that different kinds of thinking could automatically trigger lateral eye movements . The eye field on the right side of the brain is linked to the left field of vision, and controls eye movement to the left, while the left-brain eye field connects to the right field ... |
Why do bathrooms in restaurants, gas stations, hotels, etc., have the music on a higher volume than on the main room? | The bathroom may be at the same volume as the rest of the place. It may be that less of the sound is absorbed by carpet and people and chairs and things. Bathrooms are generally smaller/have less volume as well, so a single speaker set to the same volume will seem louder in the smaller space. But really, it's probably ... |
When can police get accurate speed readings on a moving vehicle? | When they have radar on and it is within a certain degree of head/tail-on. I think it's within 15 degrees, but can't remember the exact number. The further off it is, the less accurate. And when the radar is properly calibrated, which should be done a minimum of twice per shift. When the are following the vehicle and p... |
The stages in a lawsuit. | Civil or criminal?', "I'm not a lawyer, but I've been to small claims court before.

They specify the person they are sui... |
How come a doctor can't just cut out a cancerous tumour and be done with it? What is it that stops the patient from being cured? | When tumors are just sitting in places that can be easily cut open, that's exactly what they do. But one of the dangers with cancers is that a few cancerous cells can 'brush off' from a tumor and hitch a ride in the blood or lymph, forming dozens of other small tumors all over the body. It's called metastasis, and it's... |
Why do we see 'breakthrough' and 'revolutionary' discoveries in science and technology everyday but NEVER see them implemented in the real world? | A **large** portion of it has to do with exaggeration from the media and/or the scientists themselves. The scientists, journals, and universities involved in publishing the papers want to hype the results as much as possible to get the free press and fame. The reporters want to put the best spin on the paper being publ... |
Why is the campaign to free Tibet so much more popular than the Tamil push for independence from the Buddhist majority in Sri Lanka that has claimed more than 100,000 lives? | The kindly old man Dalai Lama is a much better PR face than Tamil Tiger suicide bombers. The fact that Tibet is fighting global economic power China instead of an island nation many people couldn't find on a map helps visibility too. |
Why are 6 legs plus so common within the instect world but none (that i know of) exist in animal kingdom? Why are we all 4 or 2 legs? | Well, the simple answer is that arthropods evolved differently than land vertebrates. So basically, mammals, and other land vertebrates have four legs because they evolved from a fish ancestor that had four members that were possibly used as legs. This worked as it was evolving so it never changed, and making more func... |
Can a "New Color" unlike any colors on the normal spectrum be created or already exists? If so, how? | For us humans, there are no new colors that we will be able to see. We cannot even imagine what a new color might look like. The colors that we see are determined by the number of color receptor cones we have in our eyes. I'm pretty sure we only have 3, and these 3 cones determine all of the wavelengths of light we are... |
How come we don't see new Football (or any sport) teams? Why can't Hawaii or Maryland (or any state lacking) form, recruit and join the nfl? | You realize Maryland has a NFL team, right?', "It's a big investment, you need to build a new stadium and pay the new team's salary before you know if fans will turn up for the game. That said, the NFL has expanded several times. LA is the obvious target for another move/expansion, other cities without an NFL franchise... |
Why can animals walk the day theyre born, yet it takes humans about a year? | Not every animal can walk the day they are born. The reason why human babies are so vulnerable after birth is because we are born at a very immature stage. If pregnancies would last longer, we would not be able to give birth to our babies. We are already pushing it in terms of getting their big heads through our narrow... |
Why do we feel the urge to stay in bed even though we've had more than enough sleep already? | I will stay in bed hours past when I should be waking up, just to continue living through especially vivid dreams. It's like living an entirely new life every time I go to sleep. There's new locations, people I haven't seen in a while, random and exciting action that never follows only one plot. I always want to spend ... |
How does a town buy water from a neighboring town? Is it a matter of flipping a couple of switches? | Chances are your town isn't buying water so much as the rights to water. Most towns get there water from multiple sources, lakes, rivers, reservoirs, aquifers, and the like. But they can't take all they want, they are allocated the rights to take only a certain amount. So if the river were contaminated, that town could... |
When calling 911 from a cell phone, why can't they find the location you are calling from? | Hi, I work for the Cell industry, and I can tell you a few things. When you call 911, the 911 call center needs to be outfitted with the equipment for e911. At the basic level, the 911 dispatcher can get the location of the cell tower that your phone is connecting through. With better technology running, they can get a... |

Why can humans exhibit super-strength in times of crisis? | Because at any moment, we are only using a certain percentage of our muscle mass, since using all of it at once could severely damage those muscles. When we are in extreme situations like the one you proposed, our instinct to survive or help our offspring survive overrides the need to keep your muscles intact. Our brai... |
what do voices sound like traveling through the noble gasses? | it's not about the gas its self more the density of if. noble gasses are what you call lazy. meaning they won't react with anything. helium is lighter than air so it makes your voice sound high pitch due to less density of its atoms. so find the density of are and you can predict what your voice will sound like. |
Why do foods containing gluten become sticky when in contact with water? | The clue is in the name - gluten is Latin for glue . Gluten is a mixture of proteins that are viscous, elastic, and adhesive. They actually help the foods they're in keep its shape. When the gluten gets wet, its just line activating an adhesive. In fact, there are glues made from gluten. The stickiness is largely a res... |
Why does your car key remote reach further when you put it up to your head? | Despite having visual line of site you probably don't have radio line of site. That is technically called the fresnel zone. The extra height is really what is helping you. |
Would someone whose eyesight is not good enough to see something far away be able to see the same thing if there was a photo taken of it at the same distance? | Yes, they would because the picture is much closer than the actual thing. However, if the old person took the photo they might have a hard time focusing, since they can't see what they are focusing on.i'm pretty sure you're confusing size, with focal distance. The eyes when "viewing" the mountains in real life are atte... |
What happens when my car windshield keeps getting foggy? | There is a drastic difference in air temperature between the inside of your car and the outside air. This temperature difference meets at your windshield. This causes moisture in the hot air to condense into dew or fog on your windshield.

Why do flies keep landing on the same spot, even when repeatedly being put in danger at that exact spot? | They don't think like humans, that's for certain. The fly isn't aware that it was just hit the last time it landed on your leg. It doesn't even know what a leg is. It lands on a place it's attracted to. So if it keeps coming to your leg, it's attracted to the scent or the sight of it. They don't learn your responses. T... |
why when you get sunburned you get sleepy/tired? | Sunburns usually come with dehydration as well. Mix dehydration and your body trying to repair a sizable chunk of skin, its quite draining. |
Why is it called inflation and not deflation when the value of money goes down? | Inflation is or can be a symptom of an increase in the money supply. Hence inflation. You can also think of the number of dollars it takes to buy something "inflating".In 2009 a box of Velveeta Shells and Cheese was $1.50. Now it is $2.75. A dollar is still a dollar, but you can buy less with the same amount of dollars... |
Why is it so difficult to make a new violin sound like a Stradivarius in this day and age? | While the legendary sound of Stradivarius instruments is well known, it turns out the idea that their sound is completely unique and not reproducible may not be all that true. While they are very high quality instruments, many blind listening tests have shown that most people, even those with trained ears, can't tell t... |
How can I be starving when I go to bed, and wake up 12 hours later and not feel any hunger at all? | Yahoo says The reason is that your body stores fuel [all the food you do consume and do not immediately use for energy] is broken down into glucose and stored in your liver as glycogen. When you sleep [or have not eaten in a while] your body will use the glycogen as an energy source. So when you are active [before you ... |
How does the USA have the highest health expenditure per capita and no universal healthcare? | It's at least in part *because* we have no universal healthcare that we have the highest expenditure. --When a private insurer takes in a dollar, they have to provide profit for shareholders, big salaries for executives, advertising, political lobbyists to make sure we don't adopt a better system, and all the effort fi... |
Heating a liquid usually turns it into a gas. So why do my eggs 'solidify' when I cook em in a pan? | Heating a liquid *that isn't changing chemically* will eventually evaporate it, yes. But many liquids do change chemically well below their boiling points, and what's happening in your eggs is precisely that. The heat is changing the structure of the proteins that make up much of the material of an egg. Normally, prote... |
cells, organelles and their functions *first post* | 1. The nucleus contains the DNA that codes for proteins. In order to make the right proteins for the situation, the cells responds to cues, both from outside the cell and inside the cell. In order to react to cues a signal has to go from the cytoplasm or plasma membrane where it is detected to the nucleus so the cell c... |
How do Olympic male gymnasts train to be able to do the minimum of what they do? | Former gymnast here. * There are several tiered levels of gymnastics at the very lowest level are basic skills [here] is a basic explanation of the level system. It is a bit outdated because the mens system has switched to be numbered like the women's system.* Although strength is a necessary and important part of gymn... |
What is cognitive behavioral therapy? | It's a therapist providing strategies to cope with your difficulties. My ex wife had OCD and would worry constantly about things. Sometimes big things, often little things. To the point she couldn't do anything practical because she was too busy worrying. She'd literally sit on the sofa the whole day, worrying. Not wat... |
Why does reddit "archive" old posts and comments? Why can't they be voted on anymore? | For every post and comment, Reddit doesn't just store the number of upvotes and downvotes - it stores every single individual vote so it can know who voted on it . This of course is a lot of data. By archiving it and removing this data they can remove all of the data about individual votes. Consequently they have to di... |
When did straight white teeth become a status symbol? | I'm guessing this is a thing in the States? As with so many things, it probably started to become a status symbol as soon as famous people started doing it. This being said, the super white teeth American TV stars and politicians tend to have is not really a thing here in Europe . So it's not a status symbol everywhere... |
What happens if a computer or server receives two messeges at exactly the same time? | On a hardware level, a computer can tell the difference between two signals down to the millionths of a second or so, generally. It's almost impossible for two signals to arrive at the exact same millionth of a second. I'm frankly not even sure that they would bother to put in a failsafe for if it does happen, because ... |
Why is it when you eat hot/spicy food your chest gets "cleared up"? | A chemical travels up your nose and causes a bunch mucus to be produced and that causes your airway to irrigate. |
Why can't we just cover all rooftops with solar panels to provide the world with energy? | Several reasons: 1) It would cost a huge amount of money. 2) The Sun only shines 1/2 the time, at best. 3) Sunlight is very low energy per unit area. This is good or we'd be roasted. Some processes take high energy density, and that's very difficult to achieve with rooftop solar. There are better solar solutions for pr... |
What makes a human a human? | The truth is, species is a fuzzy inexact concept. It does not have a straightforward description. You'll hear someone say, likely in this very post, "It depends on if the animals can reproduce together," for instance, which is wrong. It's a decent rule of thumb, but it does not define a species. It doesn't work for cas... |
If downloading songs off the internet is illegal, how is it legal for there to be free apps that let you download songs? | I can buy a pipe, and I can smoke tobacco, marijuana, or crack in it. Until that choice is made, it's just a pipe, and you can't say what I'm going to do with it.Only downloading copyrighted material is illegal. You are free to upload and download songs off the internet as long as the copyright owners have granted perm... |
Why do we find it difficult to get past somebody if you are walking straight at each other? | As said before: eye contact. Eye contact is typically a show of good manners but doesn't really help a person in this situation. If you completely avoid eye contact and simply look where you're going this will never ever happen unless the other person is severely confused or distracted. Usually simply glance shortly at... |
What it's the "tink tink tink" sound cars make after being turned off? | So you have a marshmallow and you put it in the microwave to warm it up. Then it gets big! You shut off the microwave before you make a mess, but then you notice the marshmallow gets smaller as it cools. The car engine does the same thing! It gets hot therefore it gets bigger! And when it cools down, it shrinks! But si... |
Why is Islam the fastest growing religion in UK ? | Immigration. It also explains the large increase in practitioners of Hinduism. [See Figure 2.3 about halfway down]', "I start a religion today I'll have a member of 1. If I add one member tomorrow then my growth rate will be 100%. _URL_1_ |
What would happen if an aircraft carrier like the Nimitz encountered huge waves (link inside), it certainly does not look that stable. | The same reason you can push over an anorexic teen easily, but would have trouble with a wwe wrestler. Because they are gigantic. The USS Ronald Reagan, a Nimitz class Aircraft Carrier, may look unstable, but remember that it is displacing 100'000 tons of water. |
why can't we come up with an efficient solution for cleaning up orbital space junk? | You have a flatbed tow truck, clean up every car on the highway, while they are moving. But it's in 3 dimensions, not one. You must be in an orbit, you must be in a certain orbit to intersect something, and you must intersect it at the same speed exact otherwise you will crash into it. The act of accelerating or decele... |
What kind of engineering witchcraft goes into handheld consoles, so that they don't heat up? | Your 3DS is a decent bit bigger than your phone , and also has the benefit of running on significantly weaker hardware. The original 3DS runs on a 2-core ARM11 CPU running at a "blistering" 286 MHz. More than likely, the total heat output on the CPU is considerably lower than current Smartphone CPUs by a serious margin... |
Why does plastic turn white when you bend/stretch it? | The plastic cracks inside, even if just a bit. This causes the plastic to refract some light instead of letting it straight through. Basically bending the plastic turns it from glass into frosted glassPlastics are made of very long spaghetti like parts called polymers. Normally these polymers are all jumbled up like a ... |
Why did avocados become so popular all of a sudden? | Maybe my perception is skewed by living in California where they 've been commonly available for a long time, but it looks like production has "only" tripled in the past 15 years, which isn't a big increase year on year, more of a slow burn. No doubt the growers are more powerful now, so you're seeing more marketing an... |
What is smell? If it's just small particles can something run out of "smell" particles? | It is just particles coming off of something into the air. > Is the object technically losing mass? Yes, but the amount of mass involved is tiny. > What exactly are the particles. There are *lots* of compounds that are "volatile" which means they evaporate easily at normal temperatures. Our noses have evolved to detect... |
How is it we're always able to differentiate between a male and female voice? | The male and female larynxes have a slightly different anatomy. In turn, that gives the voices a different quality which we can tell apart. |
How can websites like "Teefury" sell t-shirts with copyrighted characters on them? How do t-shirt copyrights work? | T-shirts with copyrighted characters can legally be sold if the company making the shirts has purchased a license from the copyright holder to do so.For the most part, they just haven't drawn the attention of the copyright holders yet. You can't legally put Mickey Mouse on a shirt. Disney can sue you if you do. But it'... |
The psychological theory of Id, Ego and (I think) Super-ego | Id = Instinct Ego = Reality Super-Ego = Morality. Your Id develops first. Its concern are your base needs desires; food, water, sex, comfort, emotions. A baby is pure ID; it doesn't consider or rationalize anything, it just feels. Your Ego develops next. Its concern is fulfilling your Id's desires within reality. This ... |
How YouTube streaming works versus how Netflix streaming works. | Streaming a video isn't substantially different than downloading and watching it. Basically, you start to download video, and when you have enough of it to start showing it on the screen, you do. Meanwhile, you keep downloading more. As long as you can download faster than you can watch, you're streaming. There are thr... |
Why do we have itches and why do we need to scratch them? | Itches are a reaction from your nerves. Some things can stimulate these nerves in a specific way. Scratching is, put simply, temporarily deadening those nerves. Some stronger histamines, allergens, poisons have a more pronounced effect, hence more scratching to "deaden" the nerve it's affecting. tl;dr, itchiness is a s... |
How do sugar, cane sugar, and invert sugar all differ as ingredients, and why do you occasionally see two or all three in one product? | This way sugar doesn't have to be very high on the ingredients list. If sugar is the #1 ingredient it makes the product look bad. But if they use 50% cane sugar and 50% high fructose corn syrup, that means they can put those lower on the ingredients list. They can also make false claims like, "Now with 50% less sugar!" |
Am I taking water away from thirsty children in Africa??? | No, but you should be aware even though water comes out of the tap whenever you want it to, it is a precious resourceIt's nonsense. There is no serious international trade in water. Two exceptions, neither of which matter in this case: All those bottles of fancy spring water. The "virtual water" in things like grain or... |
If it takes ~1000 gallons of water to produce a pound of beef, why is beef so cheap? | Because most of the water used in growing the beef falls from the sky for effectively free. Your water is expensive because it's purified and piped directly to your home, and the rancher or farmer has no ability to sell his free rain water to you. |
Why do people on bikes have to ride on the side of the road and not on the sidewalk? | Bike traffic is too fast for sidewalks and given that a bicycle can be peddled 20-30 mph a sidewalk would not work. What works is actual bike lanes and drivers who watch were they're going as well as bicyclists that obey the rules. |
Why is 24-Karat gold called "pure gold"? | The karat is a measurement of the percentage of gold present in an object, with 24 karat being defined as 100% gold. 12 karat = 50% gold. So, 24 karat is pure gold because it's 100% gold, no other metals. Pure gold is a very soft metal, you can make dents in it with your fingertips. So, for jewelry, it needs to be allo... |
How do building designers decide how many toilets to put in things like office blocks and stadiums? | Well, it's partially local law. New York in 2005 decided every building open to the public needs 2 women's bathrooms for every 1 men's room since women take twice as long, for parity in waiting time. Most cities, adopt the International Plumbing Code which describes how many fixtures are necessary. [Here's] their big t... |
What causes"cauliflower" ears in boxers or MMA fighters? Why do some have it and done don't? | Initially I was too afraid to see what this was but I love ears in a weird way so I feel like I had to. Here's what I 've gathered: Pretty common injury for boxing, martial arts, wrestling just because of the extreme force, your ears even tho they're strong get hurt by the impact. The layers of cartilage separate and s... |
What is anti-venom and how does it work? | Imagine your body as a large pre-computer office building: things are happening all the time, people are running forms all over the place, etc. Venom is like a fake form that looks legitimate, but isn't: maybe people try to fill it out, but aren't sure they're doing it right, so they double-check with someone else, who... |
How computer programming interacts with hardware. | The compiler or interpreter makes the string of binary that's actually executable. Said stream is stored somewhere, like on the hard disk. When you request a program's execution the stream of binary is pulled out of the storage area as an electric current and is put through the CPU. |
Why does beef turn brown when it's cooked, but chicken turns white? | There is a certain molecule in meat which gives its red color, that molecule is called myoglobin. Since the molecule is found in all types of meat it is the number myoglobin molecules that differ between the meats, giving them their color variation. The white meat of chicken has under 0.05% myolglobin; pork has 0.1-0.3... |
getting the wind knocked out of you. Bonus points for how to fix it. | It's a spasm in the muscles of your diaphragm. When there's a strong enough impact, your muscles get temporarily shocked. Your diaphragm can't move, so you can't draw breath. To fix it: relax, and wait. It's gotta reset on its own, not much else you can do.Lie on your back and get someone to pump your legs gently while... |
Can someone explain to me how, when we look into the sky, we can see the Milky Way even though we're IN the Milky Way? | same way you can see a forest when your in it.

Can someone explain the difference between a university and a technical school? | In the US, technical schools focus mainly on job training and associates degrees in specific fields. They're great if you want to be a plumber, electrician, automotive tech, or some other sort of skilled trade. There may be a stigma against the sort of jobs you'll likely be training for. You wouldn't be able to train a... |
Why do people still judge others for playing video games? | Probably for why it was looked down on before. It's seen as "nerdy" or unhealthy in contrast to sport or a physical hobby. However I think it's becoming less and less looked down upon. It's definitely more acceptable than it was a decade ago. I can see within ten years video games will be perfectly normal like watching... |
How does the mainstream media get away with saying Hillary won the debate when virtually every poll days otherwise? Isn't this a blatant misrepresentation of facts? | There are no "facts" when it comes to "winning a debate"; it's purely a matter of opinion. The news agencies report that, by their perception, Hillary won.
