How did the world clean up in the aftermath of World War II?
In addition to some points already made here, it's worth noting we're still literally cleaning-up battlefields from WWII . Unexploded munitions, land mines, mass graves, chemical remnants, and heaps of scrap metal dominant former war zones, posing serious risks and transforming local life. Checkout the section on Stali...
Does 0 calories always mean no weight gain?
If someone drank 4 liters of diet coke and ate no other food or drank no other water, they'd probably die. Eating at a caloric deficit will result in weight loss, though. For example, if I eat ~1950 calories per day, I will not lose or gain weight. If I eat more than that I will gain weight, less and I will lose weight...
Why is it required to perform some tasks on a PC as an administrator, despite there only being one user account anyway?
Your normal user account should not be the adminstrator account. You only want to run programs with full privilege when they really need it. If you end up downloading malware or there's an exploit in some software you're using, you don't want to be running as admin, becuase then the attacker can do literally everything...
Why didn't the spanish or portuguese colonies form their own united states of America?
[They did.] Besides Mexico, they didn't last long. Mexico was a bunch of Spanish colonies that formed into the *United Mexican States*. Colombia, Venezuela, Ecuador, Panama, northern Peru, western Guyana and northwest Brazil formed into [Gran Colombia]. Then there's the [Empire of Brazil], which consisted of Brazil and...
If water is transparent and colourless, why do things go darker when they are wet?
I don't really know much but not everything turns a different color when wet. In the case of a t-shirt , yes it does get darker. I believe this is because less light is reflected off of the fiber because the water inside* the fabric will consume* that light. *Those words may not be the correct use of the word in regard...
Durring the week i can get 8 hours of sleep and feel like i got 2, but durring the weekend i can get 5 hours of sleep and feel like i got 10. Why?
I'd bet money it's because of _how_ you wake up. If you're waking up when your body feels like it, of course it'll be easier than if you're just getting up because your alarm clock says to, regardless of how much you actually slept.
why are currency symbols written before the numbers when they're pronounced after?
Because in your language, the process of sentence structure is generally made from left to right. Placing the currency symbol before let's you have a small heads up that the following numbers will be involving a specific currency. This is the same reason why Spanish uses an upside exclamation or question mark prior to ...
Why is rouble falling?
One of Russia's most valuable export is oil. Right now the price of oil is low and sinking deeper. Investors are getting jittery about Russia's financial future.
How can the laser on the mast of NASA's planned 2020 Mars rover be used to identify the elemental composition of surrounding rocks?
By acting like a heater. You can measure the composition of a substance by heating it up and seeing what the light looks like coming off of it. A gas chromatograph mass spectrometer can do this in most labs by taking a small sample of the substance to be measured, and heating it up until it vaporizes and then looking a...
How exactly does the moon control tides?
Without a moon, both the earth and the ocean would be spheres. Because it can flow, the moon [bends] the shape of the ocean a bit, so that it's more like a football with the solid earth in the middle. There's actually two high tides. One bump points toward the moon, where the water falls toward it; and the other bump p...
How did dogs become "man's best friend"?
Both were and are very social, 'pack' mammals living in the same environment and time frame. The ability to identify and understand such 'similar' behaviours were key to help early humans in hunting. We enjoy each other's social capabilities, and the submissive aspect of canines has been used to the great benefit of ou...
Why is it nearly impossible to print your own checks?
For the most part, checks are easier to have preprinted than go through the hassle of manufacturing your own check. While a one-off, hastily scribbled note on a napkin *can* be a legitimate instrument of transferring money, there's a lot of verification that has to go into this kind of thing and banks discourage it bec...
Why USA jokes a lot about Canadians?
Because we secretly wish we were Canadians. Everyone's friendly, gets free health care, and is always eating Tim Hortons.
How is Linux more customizable than other operating systems?
I just checked your post history. You ignore that most people there gave you good answers. Yet you crap on the whole subreddit because of a couple people that didn't. And judging by your follow-up thread, YOU are more rude than anybody on /r/linux.
How was it possible for great martial artists like Miyamoto Musashi to practice/hone skills in complete isolation, then use it on another opponent? Wouldn't they need to spar to develop those skills?
Actually, Miyamoto didn't train in isolation when he was younger and was quite a good swordsman because of his training with his father,uncle and a swordsman school. quoted from the wiki:Training in swordsmanship 'It is said that he may have studied at the Yoshioka-ryū school, which was also said to be the school Musas...
Why is it preferable to have illegally obtained evidence thrown out of court as opposed to keeping it and prosecuting the one who obtained it?
If the illegally obtained evidence was admissable, a lot of renegade cops would break the law to get evidence and take the slap on the wrist that came with it. They'd end up violating a lot of innocent people's rights on their way to justice. Also, it'd likely be a slippery slope. If you relax standards and let cops ob...
How come you can look at welding on TV but are told it can blind you if you look at it in the flesh?
The arc rays are extremely bright in person, your tv can't output as high of a brightness so that's good for you. TVs will never get bright enough to damage your eyes, it'd be a class action lawsuit in no time.
I've heard it said that spidersilk is stronger than steel. If thats true why can it break so easily with a stick or finger?
If you had a string of steel that was as thin as a spider web, you'd be able to break that with your finger too. On the flip side, if you had a spider web as thick as a steel cable, it would be incredibly strong. Also, I've usually seen that statement made for *tensile strength,* which is the strength of a rope being p...
Does the camera really 'add 10 pounds'?
While I don't doubt that there's a psychological affect at work for a lot of people, what you're actually seeing is just the distortion you get when projecting a three-dimensional object onto a two-dimensional surface.
Why dose it always look like construction workers stand around doing nothing
Electrician apprentice here. Been doing a lot of underground work, and I can say that a lot of our standing around is a result of running into an area where other contractors are working, or the foreman read the prints wrong and we have to go back and dig a large portion of earth up to lay more pipes, that we just buri...
What is it exactly that ISIS wants?
ISIS's goal is not terrorism, they are really militants that commit acts of terrorism alongside a much, much bigger non-state military involvement. The end goal of ISIS is an Islamic militant state in the middle east / mediterranean, if not further. ISIS hates America, and hates Europe only because they stand against t...
why do limbs sometimes feel as if they’re vibrating when going numb / why do limbs go numb at all
Vibration is sensing pressure, your pressure receptors are bring disrupted and essentially sending 'false' information to your brain
Why do people prefer "Judeo-Christian" over "Abrahamic"?
Because that's what's been used for a while now to describe American culture or values, which are based on Jewish and Christian ideas/beliefs. Muslim ideas/beliefs tend to be excluded from that, rightly or wrongly. But people are trying to get them included by using the term Abrahamic instead, rightly or wrongly. _URL_...
Why is the multiple-choice format of testing so widely used?
They're used because they're easy to take and easy to grade. Also, your math isn't really a concern because any class that is concerned about grades being inflated by the testing method can just curve the grades. In a system where the grades are curved it doesn't matter what percentage you get correct compared to the t...
If a closed room has a 100W fan running inside, is the room being heated by 100W?
Yes. No other answer is correct. Yes. 100w fan or a 100w heater in an insulated room is the same. A heater adds thermal energy directly. A fan adds mechanical energy that becomes kinetic energy in the air that eventually dissipates to thermal energy. Yes, each step is inefficient, which just helps the energy convert to...
Why wouldn't federal legalization of gay marriage violate Separation of Church and State?
The government doesn't make Catholics marry non-Catholics or even divorced Catholics, but government offices still accept paperwork from and issue marriage licenses to non-Catholic couples and Catholics seeking to remarry. Nobody seems to think that this arrangement is discriminating against the Catholics. Why is the s...
Why do horses have to be put down when they injure their legs?
Horses just don't recover from leg injuries well. A dog is light enough to get by on 3 legs, a horse isn't. A dog spends a lot less time standing than a horse does, and can easily sit down and stand back up again with just 3 legs. And perhaps most importantly, horses are very strong, very nervous animals, that can frea...
why you need to make a point of saying [EDIT] when you make the smallest mistake on Reddit. Why can't you just fix it.
Before Reddit was taken over by middle- schoolers it was important to document your edits because when you were having an adult conversation you want to know that the person you were having a discussion with isn't changing what they said.
why is it that stuff like sharpies, gasoline, etc smell so good to some people but horrid to others?
Perhaps it's that some peoples' noses are more sensitive to harsh fumes from these chemicals. I know the strength of the sense of smell can vary greatly between different people.I think its similar to the effect drugs have. The smell of Gasoline has a numbing sensation to it that some may enjoy, and others may not.I lo...
If you are travelling in a car at 50mph and there happens to be a fly in the car with you, is the fly also flying at the same speed when in flight?
From outside, if it's flying from the back to the front, it's flying faster than the car, and if it's faster, and if it's flying to the back is slower, to the fly it's just slightly harder or easier because it has the the car momentum to push him. Same principle when you are on a train, at constant speed it shouldn't n...
Why do most hard candies just shrink down as you suck on them but peppermints get all porous and full of holes?
My dad worked for Lifesavers and worked on Lifesavers mints, so I've learned a thing or two about this. Peppermints often start out as a powder that is pressed together with a lot of force - I've even watched powder go into machines and mints come out. As you suck on it, the powder comes apart a bit. In contrast, hard ...
What's stopping us from predicting the weather/future by simulating earth-like planet on simulators.
Think about trying to capture the current state of the world all at once. You'll need the temperature of the ground, wind direction/pressure everywhere simultaneously. Even if you could, that is a lot of data and processing power to keep up with it. A similar effort is ongoing with mapping brains. Here it is a little e...
Why is/was NWA so important?
One of the first groups to glorify real street violence as a lifestyle. There were other groups at the time from the east coast that glorified drugs and sex[] but West Coast rappers spoke much more aggressively and much more about shooting people/selling drugs/disrespecting authority. Check out [Compton's Most Wanted] ...
Why is it that American spelling of certain word omits the 'u', as with 'color' and 'favor' etc?
It can also we said that Webster proposed many more changes in spelling than those that became use. What's even more interesting is the words, spelled the same, that mean different things in the UK or US. And the US English words that are considered archaic in UK English.
What limits replicators in Star Trek? Why can't they just make any substance/machine they want?
Replicators still obey Conservation of Mass/Energy. If you Replicate something, you're using up mass that you got from somewhere else. The most common thing that Voyager was looking for was Dilithium Crystals, which are the fuel source for their Warp Core. Even if you can replicate them, you use up more energy than you...
Why is it predators are reluctant to attack us?
When you go to the grocery store, do you just grab random stuff and put it in your mouth without knowing what it is? Or do you prefer to eat things that are familiar? Animals grow up eating certain prey species. Humans are not normally among them. They do not like to prey on things they find strange and threatening. Ma...
Why do we have both a North and a True North?
Magnetic North isn't exactly at the north pole . In fact it moves around with time, and isn't consistent for all locations on earth.Alright, thanks for the explanations, but I got one question. If I want to go North for whatever reason, do I follow the North or the True North?', "On iOS developers have access to the co...
Does Diet Coke still have the ability to make you put on weight?
I'm just an average person, but what I've heard is that the sugar substitutes in diet coke trick your brain into thinking it's received sugar but when it doesn't get the sugar it thinks it should have, it starts craving it, leading to more hunger and eating more, which can make you gain weight.
How do singers prevent themselves from coughing, burping, yawning and sneezing on stage?
In my experiences , adrenaline plays a big part. In the moment, whatever you're physically dealing with goes away, and you're able to perform.
Why do illegal immigrants who are already in France - a safe, prosperous developed nation - want to get into the UK so badly?
Precisely *because* the UK is slightly harder to get to , they've never had to be so harsh on asylum seekers. So laws that exist in most places on mainland Europe - in relation to the rights you have while awaiting asylum, how difficult it is to live / work illegally in the country and most importantly how difficult it...
Why do companies care if their stock prices go down?
The biggest reason is many companies pay some or all employees with stock . So declining stock price means pay declines retroactively which tends to make the best employees seek other employment.because the owners of the company care. who are the owners? the stock holders!Because that means their company is less valuab...
From the United States, you need visas to travel to some countries, but for others, passports will suffice. Why?
A passport identifies you as a US citizen. A visa is permission to enter a country. Most countries require a visa in most circumstances, because they want to keep track of who enters, and don't want people who stay and become indigent. They often wave visa requirements for friendly/rich countries where this isn't an is...
If cars in the 1970s were getting 30-35mpg, why are we struggling to get to that with all the new technology coming out?
Cars certainly didn't get 30-35 MPG in the 1970's. Even small cars like the Pinto and Vega didn't get 35 MPG. I had a 1972 Impala. I don't think it ever broke 10 MPG.Those cars were pumping out ridiculous amounts of NOx. Modern cars have catalysts that prevents them from turning all limestone in the local area to grey ...
How does sodium pentothal a.k.a truth serum make people tell the truth?
It's not a truth serum in that it forces you to tell the truth. It just makes it harder to perform higher-level brain functions. Figuring out the answer to a question and then consciously choosing to lie is a higher-level function than simply answering the question. Basically, it makes you so dopey that you don't have ...
Why can't machines be powered by food and water?
Food and water aren't very effective sources of energy for one. Normal food will get you a few thousand calories while the same amount of gasoline will give you 10x as much energy in a simpler process", 'The real question is "Why can't humans be powered on fossil fuel?". Food is actually a terrible source of energy. It...
What would happen if the speed of light doubled?
I'm not a physics expert, but as far as I know, as you start moving faster time begins to slow down. If you were to graph that, you would see an asymptotic curve, with the speed of light being the asymptote. As you approach the speed of light, instead of moving through space faster time just slows down . If we're looki...
What is "Genderqueer"
For those that are asking about non-binary genders, take a look at the Samoans with their [Fa'afafines] and the Albanian [sworn virgins.] Maybe the most famous example is that of Eunuchs in ancient Mesopotamia. By getting castrated, they were allowed to act in a different cultural space than either men or women. There'...
How does DNA 'know' what to do?
To understand how this works, you have to let go of the idea that anything on this level 'knows' anything. Things work because if they didn't, the organism would die and we wouldn't see any of that thing's offspring. DNA is read by structures which copy sections and release bits of RNA which float around and then inter...
What is Pi? Why does it exist? Why was it created? And why is it "infinite"?
Pi is the ratio between a circle's diameter and its radius. Mathematicians knew there was some constant ratio , and after a lot of hunting, they found the link to be roughly 3. After a lot of refinement, they found it to be 3.14, then 3.1415926, then on and on more and more. The reason it's infinite is because there wi...
What benefits are there to dilluting US federal power and emplowering US state governments?
besides the answers given it also allows for 50 'tests' to be done with a set base while the variables are allowed to operate and ideally permits people to go to the places that the tests are doing well and they agree with what is happening", 'Different people have different idea on how they would like their government...
How can hackers 'only' steal part of a user database?
Time is the most likely answer. If you try to steal every cookie in the cookie jar, you'll have a hard time holding them all and you'll probably get caught. If you take a few of them, you can sneak off before someone catches you.
Why is handwriting from the past so much prettier than writing now?
People didn't have much in the way of alternatives before the typewriter was invented. You either wrote by hand or not at all. So there was a lot of emphasis on having good handwriting in your letters and documents and people just got better at though the sheer amount of practice they were getting from early on.Its a s...
How do dogs know not to jump out of the truck bed when their driver is speeding down the highway?
They don't. I had a dog jump right out of my Jeep when I was driving through town one day. She learned her lesson though, and she hasn't ever done that again.
Why do so few toll road booths accept credit cards?
Because we're already a step ahead of that with electronic toll collection. Ever heard of E -ZPass? You don't stop at all when you pay a toll with E -ZPass or whatever electronic toll system is offered in your state. It doesn't make sense for a toll plaza to have more than 2 or 3 types of booths, so most of them only h...
. Why did old dial-up modems sound ridiculously annoying? Couldn't they mute it?
In addition to the other reasons given - one reason you needed to hear that was each connection you configured often needed to be tuned for that specific service. The telephone system could take a second or three to hand your call off from the local to the long distance service and then the other end's local exchange m...
If currency exchanges only ask for ID if people exchange above a set limit e.g. $3k, what's to stop money launderers doing it $1k at a time at different places?
As those before me have said, you'd have to spend a lot of time and effort to make this happen and it would be very difficult to repeat. Banks have similar policies about cash deposits / withdrawals above $10,000. Now, you don't have to shows ID and fill out a Currency Transaction Report if it's $9,000 so you won't get...

How do phobias develop?
Let me know if I'm on the right track. I think phobias are similar to allergies. In an allergy, the human immune system overreacts to something that it thinks might be harmful, and the overreaction can be strong enough to seriously harm you, if not kill you. Phobias are like this, but with a difference. Most phobias ar...
Why do cops not sit outside of bars and arrest anyone getting into their car?
I know for a fact that in some places, the bar owners give the cops a few bucks to stay away. If the bar owner pisses off a cop, the cop sits right outside the bar, and that seriously cuts into the bar's business. I asked my old boss one time where the stained glass windows in the bar came from and he told me all about...
If I am/my kids are vaccinated why should I be afraid of those who are not vaccinated?
Another thing people haven't mentioned is that some/many vaccines wear off over time. So even if you received a vaccination at school age, by the time you are in your late twenties some may have worn off enough for you to become sick if you then encounter one or many people with the disease. For childhood illnesses, wi...
What is the evolutionary advantage to different coloured eyes?
Eye colour doesn't confer a survival advantage in the same way skin colour does. Different eye colours don't see better or farther. Although there is some evidence to suggest that lighter coloured eyes are more sensitive to light. Regardless eye colour isn't really going to affect your chances of living. It however, mi...
Why do we get dark circles under our eyes sometimes, even if we get enough sleep?
As someone who has dark circles, I have been told it's a combination of thin skin and deeper set eyes.I think it can be somewhat genetic too. Since I was young I 've had them as a pale blue purple. Sometimes they get worse after drinking and lack of sleep, but since I was 11 or 12 I 've always had them. Once was asked,...
How do modern mercenaries operate?
I've been a private security contractor for 10 years. A 'mercenary' if you like the term. Like most Reddit comment sections, a lot of good answers here, a lot of crap. Put too much faith in knowledge derived from fiction and documentaries and similar external assessments, you'll always get the wrong answer. The common ...
Why do passenger planes choose impact over parachuting passengers out?
Firstly, when was the last time you heard of an in-tact plane crashing into the ground when the failure started at normal altitude? This pretty much just doesn't happen. If you have a failure at 32,000 that isn't catastrophic _right then_ , then you can likely safely descend. In order for the parachute to even be sensi...
Why is gambling considered so immoral?
The bible says you will have no masters other than God. An addiction is something that controls you. They figure you'll get addicted, so therefore gambling is sinning. But so is alchohol tobacco and Reese's McFlurries", 'In society, we often consider self-destructive activities to be immoral. It is common knowledge tha...
Why do some people cry during sex? Is it biological or psychological? Both? Are there performance or dysfunction related to crying during intercourse?
Semi-relevant: Why is it that in nearly every porn video involving an Asian female, she looks like she's crying in pain the entire time?", 'My ex girlfriend cried the first 10 or so times we had sex. Very strange to me, as I thought she might have had some kind of sexual abuse when she was younger, but she just ended u...
Why does McDonalds have a site especially for black people and how is that not racist?
It's likely a calculated maneuver that enhancing the brand among that demographic with a unusually high level of racial targeting was worth putting up with some criticism because the criticism would not be very harmful overall. It doesn't really leave a bad taste in my mouth, really. I do think it's a bit silly that it...
"Bologna is a deli meat for people with eyes." - Mitch Hedberg
Dogs are forever in the pushup position", and "I'm against picketing but i don't know how to show it".. IMO, judging from my interpretation of his sense of humor, I think [it's very likely this.]
What's the deal with Muslims in the U.K.?
Its not some kind of widespread epidemic or anything, as someone else said, places like Birmingham and Bradford are the hubs of the English Islamic community to a degree. This is normal though. Different parts of a country have different settlements. I'd say the Polish communities stand out much more but the media obvi...
Why is American Nutella just not as good as European Nutella?
[Here's an article] about someone doing a side by side comparison. Apparently there is no significant difference in ingredients, but there may be a difference in trans fats or the roasting technique for the hazelnuts.Wait your saying there is even better tasting Nutella 0_0?
What would be the issue with implementing a system where people's fines reflect a percentage of their incomes?
This is already done in some cases, if I understand correctly. Like, if a corporation like Apple fucks up and is fined, they pay millions, but if Joe's workshop at the corner of the street does the same he is fined a much smaller sum. I'm not sure what the specifics are though.They have such a system in Finland. Some g...
Why is international calling still ridiculously expensive, but video chats to these same places are free?
Because carriers can get away with it. They could easily lower the prices by 90% and still make a profit, but why should they when people are willing to pay? Almost nobody chooses their phone carrier or plan based on the international calling fees. For most people, international calls are rare but when the need them, i...
Why aren't lie detector tests used more in the justice system, and if it is because they are inaccurate, why haven't more accurate detectors been developed?
Well, it's a form of self-incrimination. So you can plead the 5th to skip it. And a smart lawyer would probably want to keep their client far away from one of 'em. Additionally, yes, they can be beaten with some readily available medicines. And companies out there are working on more accurate ones as we speak.
How do animators sync video and audio so fluidly?
To see an old fashioned way it was done, check out this excerpt from a [documentary on animator Lotte Reiniger.] It shows the score, literally written out as sheet music, with the number of frames needed for each measure. The shots are then planned accordingly and recorded in her shot log. Things are of course differen...
why most lottery winners are poor after a few years
One big, often overlooked factors is that a disproportionate number of lottery entries are from compulsive gamblers that means they also win more. It doesn't matter how rich a compulsive gambler is, if they don't find a way to control their addition, they will lose all of their money.
Why isn't this law changed?
Cases like you cited where the criminal was extremely remote from the rest of the crime are rare outliers. Most often it's two perps that commit a murder together leaving no witnesses, if each says the other did it there was formerly no way that either could be held responsible. Or someone that had an active role in a ...
Prolapse porn - aren't these performers seriously damaging themselves?
No, its not safe. Especially not anal as it can cause permanent damage since it wasn't made to have foot long appendages thrust in there. If you get to crazy you can permanently damage your anus and then you will either face surgery or rectal leakage and bleeding tl;dr do crazy shit to your anus and your anus will do c...
Can someone explain what standard deviation is? (wikipedia is impossible to understand)
Say we're measuring salary. So you know what an average is, right, because you're really smart for a five year old? Let's take a bunch of numbers of salaries, and we're going to figure out when the meet in the middle. We're not picking the most frequent number, that's the mode, and we're also not picking the number tha...
Why do I feel more tired after 11-12 hours sleep than after 7-8 hours sleep?
When you sleep, your body is smarter. Your brain likes to do things in groups while you sleep, for a certain amount of time. When it's done doing one thing, which takes about 1.5 hours, it takes a short rest before starting again. Sometimes, when people sleep for a long time, they wake up because of an alarm or somethi...
What happens in my body when I don't eat for an entire day?
Well, tisha b'av was a few days ago, an important Jewish fast , day happened, so I can tell you what it *feels* like. I'd love to go full on story mode but I'm on mobile. For me, I didn't actually feel too hungry during that time, for some lucky reason, but as every hour goes by your body slowly weakens and becomes exh...
Why it's necessary to pre-heat an oven when cooking frozen food instead of just putting it in once you start it.
I imagine it's because different ovens have different rates of achieving set heat. That being said, manufacturers would have a hard time putting a cooking time instruction that doesn't result in a high number of complaints about the inaccuracy of instructions
Why do I fall asleep so easy when I'm not supposed to (ex: work meeting) but struggle when I am supposed to (ex: at night)?
Don't expose yourself to any bright light for an hour before you go to sleep When the time for sleep comes turn off ALL lights Make sure you do this at the same time every night or it won't work. I GUARANTEE you will sleep easily, but like I said its important to have it the same time every night. Of course you won't d...
if there's an car accident and the person at fault dies, how is insurance handled for the person who wasn't at fault?
The person's estate that was at fault is responsible for the loss caused by them. Before any inheritance can be drawn from the estate to any beneficiaries, their dept had to be paid. If negative, the claimant won't get as much as they may be awarded.
Why does my dog feel compelled to place his paw on me when I pet him?
I'm also interested in this, ive got such a placid and obedient dog and she always likes to have her paw over my hand/arm when I'm stroking her. She's done it all her life and as an adult never tried to push the boundaries.
From my actual 5-year-old: "How do you know that the world is real?"
A five year old isn't having some existential crisis. He or she probably had a bad dream once and someone said it wasn't real. The problem a child faces is that a bad dream does feel real. As children we discover that things we thought were real are not. What is worse is that we were told they were real by the world an...
How is it that there is a chance of somebody dying while they're under anesthesia?
Usually when you're under, there is also someone cutting in your guts with very sharp knives. So, there's that
Why do abandoned buildings exist in cities like San Francisco and Manhattan when housing is in such high demand?
I think it's often that developers are sitting on them or people are sitting on them waiting for the developer to make the right offer. Here in Toronto, there's a weird cycle where things get really rundown right before a huge, expensive condo goes in. Why put money into the building when you know it can do nothing to ...
How are Netflix originals profitable? Since they're released to everyone paying monthly, there is no way to earn money from them, right?
Product Placement! Any time you see a scene where they're fiddling with the gps in a car and you see the model of the car, or they're eating pizza from a Pizza Hut box and comment on how great it is , they're being paid.
How was the DNC primary "rigged"?
It's worth mentioning that the Associated Press declared Hillary the presumptive Democratic nominee on June 6th, the night before the California, New Jersey, New Mexico, Montana, Puerto Rico, South and North Dakota primaries. Bernie still had a chance at this time, but I'm sure the announcement dissuaded some from voti...
why isn't California being abandoned by the residents because of the drought? They will be bone dry by next summer.
Well . some of us *really* hate our neighbors and relish the chance to go road warrior on them. Others simply can't find jobs elsewhere and moving your stuff across state lines is expensive. I've actually wanted to abandon ship with the state for awhile now, but I need to get a job to afford rent somewhere else while I...
How does music get stored in wave form when at each time there may be up to 7 or more intruments at the same time? Pic for better understanding in post.
It's not in the technology, it's in your brain. The waveforms of all the instruments are summed up, that is all. Your brain is just that good at separating the resulting waveform into the original instruments.
What is "pressing" in football (soccer)?
Pressing for me is the best part of football I love it a lot . It's the act of closing down the man on the ball and limiting his passing options so he makes a mistake or goes for a un achievable pass which recycles possession to you . Great examples are Borussia Dortmund Barcelona under Pep Guardiola and Liverpool unde...
Are there truth to people's common tendencies when it comes to astrological signs? If there is no scientific truth behind it why are people of common signs show similar behavior, personality, demeanor?
When astrology was invented humans diet and nutritional intake changed seasonally. The amounts and type of nutrients available fluctuated through out the year a lot more than it does now. This variations in the amount of proteins, vitamins, minerals etc. that a fetus would intake at different stages of development. For...
In old cartoons, movies, and tv shows, the character when given a coin will bite it. Why???
I really like /u/Madaboutsnails 's comment. I might however take it one step further: Your mouth is a great chemistry set, and chemistry is an unforgiving mistress. If we assume that a gold coin has to have three properties 1) be the right size, and 2) be the right weight, and 3) have the right color, then there are a ...
Why are we talking more about colonizing Mars instead of colonizing the Moon?
A colony, by definition, is self-sufficient, or close to being self-sufficient. We don't need to colonize the moon exactly because it is easy to get there. We can go there and come back without too much trouble, it doesn't need to be self-sufficient. And there is really nothing of economical value on the moon, so why b...
If you charge a dangerous animal such as a bear in the wild, will it run or stand its ground?
Most animals will run. With the exception of maybe Silverbacks, or grizzlies. Cats don't want head on confrontation, they'd rather jump on your back when you don't see them. Where I used to live I would have 3-5 black bears in my yard every damn day. They were bold stealing fruit from my trees and my garbage when they ...
Why must we take medicine "with meals" or "on an empty stomach"?
Some drugs are very dependant on the enviorment around them to how much drug is absorbed into the body. When you test a drugs solubilty in the lab you don't test in water but in simulated gastric fluid. FeSSIF simulates fed, FaSSIF simulated fasted. You can also simulate gastric fluid FaSSGFof the entestines since some...
How can Chik-fil-a say that their chicken won't cause a peanut allergy reaction, even though they use peanut oil?
The part of the peanut that causes an allergic reaction is the proteins in it, not the oils. However depending on the method used to extract the oil, it can still contain the protein within it. Cold Pressed peanut oil will contain more than enough of the protein to trigger an allergic reaction. Meanwhile, refined Peanu...
How are the countries involved in the "Arab Spring" of 2011 doing now? Are they better off?
I've lived in the middle east for more than a decade and i can tell you the arabs have a culture of one-upmanship. The Tunisians actually woke up and decided they needed a change and went for it with full clean intentions and once it was done they settled down and looked towards the future. The other arab states just j...
The 2038 problem. What is it really and how would it effect us? I tried to read on it, but I can't follow really.
Here's a truly ELI5 answer to this question: Imagine that you had to keep track of time by only counting on your fingers. Pretty easy until you get past 10, then you have no idea where you're at. Since you don't know what number you've counted to, you're going to throw out a bogus number. Imagine if someone asked you t...
