When light hits somet... |
What prevents countries from achieving a global monopoly for any given commodity? | If China started buying gold and platinum, they price would begin to increase drastically as the available supply shrinks. Also, gold is pretty useless, so it wouldn't affect anything other than the price of gold. Platinum is actually a useful metal, though. The US does not have a military monopoly, as is evidence by o... |

I grew up in a country that used water+soap to clean afterwards, but when we moved to Canada we were kinda surprised that people were fine with a few wipes of tissue.Obviously you people haven't mastered the wipeless poop.Because it works? We still wash our hands before leaving the bathroom. From ... |
How is reddit able to handle so much content, why is reddit so fast? | > Reddit was originally written in Common Lisp but was rewritten in Python in December 2005.[42] The reasons given for the switch were wider access to code libraries and greater development flexibility.

A movie I like is airing on TV and I feel compelled to keep it on even though I own it already. Is there a name for this? | My hypothesis is that it's a form of transference. In the same way that the therapist brings relief to her patient - who then becomes romantically interested in her as a result of associating her with that relief - you associate both the ice cream van and the movie with rewarding and fulfilling emotions, having enjoyed... |
How can ESPN lose 10 million subscribers. Don't you have to pay a standard cable package? | No, most cable providers these days allow you to pick and choose groups of channels to add to your bill.

There's also New... |
why are babies generally considered "cute" and old people are generally considered "ugly" | Babies have large eyes! Babies have large heads! Babies have soft skin! Old people do not.

How does a store make money on gift cards for another store? | Yes they make money. The most common way is that they get paid a fee per card that they sell.

States with cheap gas d... |
How come insects such as bees, mosquitoes and bedbugs never target eyes? What would happen to our eyes if they got stung? | Bees might - but I doubt it. The eyes are a relatively small area of the body. Even if insects chose a spot at random, they would rarely hit the eye. As for mosquitoes, bedbugs, and other bloodsuckers, they require your blood to complete their life cycle. There is no blood in your eyes, and very little in the veins aro... |

Why don't more websites host their downloads via torrents? | Torrenting requires people to already have a properly configured client.

Why do news publications acknowledge it as the "Democratic People's Republic of [North] Korea" when it so clearly is not a republic or democratic society? | Because that's the name of the country. It doesn't have to make sense to us, but that's the name. I knew a girl named Chastity in high school and I know for a fact she didn't deserve that name. But we didn't change her name for her. |
One day they're there and the other day gone after construction! How on earth are cranes made!?? | I presume you're talking about tower cranes - the type with the tall metal lattice tower?

Why do we go through so much security to get on an airplane but virtually none for any other mass transit? | Mostly not especially logical hysteria post 9/11 for things like taking off your shoes and not bringing liquids. But airplanes have always had more security because airplanes are more vulnerable to attack and hijacking since they're so hard to operate. If I want to take over a plane, I can kill the pilot and copilot an... |

How come Flash and complex HTML5 games run smoother and faster than a basic Javascript-animated site? | I'm a little confused as to what you mean by "HTML5" games. HTML5 scripting is done with Javascript, so HTML5 games /are/ Javascript websites. HTML5 just provides the < canvas > element which basically allows you to say "here is a space on the page, and here is how I'm going to draw on it" . Your computer can use this ... |

the benefits of being legally married | I've been married a few years now and most of the benefits are more subtle. that is, the way in which you and your husband/wife are viewed by others.

why don't companies like yellow cab update their model to be more like Uber? | If you bought a taxi, license, the meter and signed a franchise agreement with someone like yellow cab, you did so based on certain revenue expectations. As /u/homeboi808 said, a medallion sells for a lot of money, if you bought it on certain revenue expectations, lowering your price and therefore net revenue might mak... |
Why in some cultures only the receptive partner is considered "gay?" | I think it has more to do with the receptive partner being the one in violation of gender roles. Men are expected to be the *penetrator* during sex, so to be the one being *penetrated* is considered unmanly. They're the one "deviating from the norm." This obviously only applies to gay men though. I don't know if an equ... |
How do brands and designers become high end? For example, what’s so great about Jimmy Choo? | Some people decided it was a trendy brand, or it had some celebrity endorsement, or high quality/rare/expensive materials.

Then you have the different types of touch screens .lol |
how hard is it for a homeless person to get a job after they become homeless? | It's essentially impossible. Studies have shown, however, that if you buy a homeless person a suit and tie and lend them a place to stay for a month or two that they almost always find work.

Can a dead body wash up immediately or does it have to become bloated first, how does that work? | Anything in the tidal zone can wash up to shore. Sort of a crap shoot if it is going to go out to sea or wash up. Mostly dependent on of tide is coming in or out.

What really happens to your flash drive when you remove it without ejecting? | Nothing really *happens*, but if you're actively reading or writing from/to the drive then a sector could become corrupt. Safely removing an external drive was primarily an issue with floppy drives as it was practically a guarantee you'd fuck it up. I still am super obsessive though and make sure to always safely remov... |
Why is eye contact seen as aggression in some animals? | The way I see it is that some animals see it as a challenge to dominance, that if you don't avert your eyes from them you are trying to act superior to them, I'm sure someone will be far more correct on this than me though. TL;DR Looking them in the eye is a challenge to their dominance, avoiding eye contact is being s... |
How come some soap leaves my skin feeling "waxy" after the shower? | First, it's been a few years so someone please correct me if I'm wrong. The way it was explained to me is that extremely basic chemicals will break down your skin just like an extremely acidic chemical might. In the case of soap, your skin is actually turning into this soapy material as well because it's reacting to th... |
How did "Curse Words" become "Curse Words" and what makes them worse than other words? | Most of them deal with either very serious or very private situations. If you believe Hell is a real place and involves eternal torment, then maybe Hell and damnation aren't things one should talk about lightly. The other big curse words like fuck and shit deal with things that are either very personal or very gross an... |
Why screens will trick our brain as daylight to make us awake, but in actual daylight time we are tired? | Our brains have evolved to associate this blue light during the day to an optimal time to be awake and active. As the sky turns red then dark our brains naturally release chemicals that make us feel tired. This is the basis of the [circadian rhythm]. Screens produce a lot of blue light which tricks the brain into think... |
If constellations aren’t real, why the personalities stated for each zodiac seems legit? | Because horoscopes are intentionally made to be vague and easily attributable to anyone. This is why in double-blind tests there's no established pattern of recognition better than random chance in picking one's own horoscope. Basically, make every horoscope vague enough, and people will see something about themselves ... |
How do repressed memories work? | most of the time repressed memories are false memories created by an unskilled therapist. _URL_0_', "Others have covered that 'repressed memories' are usually fake, but the interesting thing is the 'why': It turns out your brain is more than capable of *creating* memories, given enough prompting. When you're walked thr... |
What happens to a charger that's plugged into a power outlet but doesn't have a device attached? | Wall adapters and chargers are almost always AC to DC adapters.

With 44 presidencies since 1789, why is it we only hear of a select few? | First, the US has 44 administrations, but only 43 different presidents. Grover Cleveland was the only US president to hold 2 non-consecutive terms, so both his terms are counted as different administrations. Even in such a small group as that, you can't expect every president to be a stand-out. William Henry Harrison, ... |
How can Banksy create an entire themepark (Dismaland) if nobody knows who he really is? | Banksy has an agent, and all communications with him go through that agent. The agent is the one who confirms if something is really done by Banksy and is generally accepted as the authority on his works in the art communityOne theory is that Banksy is a collective of well known artists working together globally.slight... |
Why are the repeating radio signals quickly dismissed as being potential signals from extraterrestrial lifeforms? | They compare them to what manmade signals would sound like. They dont appear similar at all. They arent dismissing them easily. They are heavily investigating them and can tell they likely arent from a source which would be intelligently controlled. The wave patters just dont match to something that would purposefully ... |
How do you calculate depreciation recapture tax? | I assume this is capital gain from 'real property' you are calculating the tax on? If so, you will apply the 25% tax rate to the entirety of the amount that was depreciated over the course of the ownership of the asset. Then, subtract the same total depreciation amount from the total capital gain from the sale to calcu... |
Foods with 1 or 2 grams of sugar/serving--what difference does this relatively small amount of sugar make? | I advise you to weigh 2g of sugar, and see for yourself that 2g is not all that small! It adds alot of extra flavor, try it out :)I suppose that really depends if you are diabetic or not. Sugar is naturally occurring, so it can just be inherently in the food that you are eating . But its in there and thus must be legal... |
Why does our sense of smell bring back extremely strong, vivid memories? | I have the the opposite. Old memories occasionally bring back extremely vivid smells. Like I once remembered this old computer I had, and I could have sworn I smelled a load of floppy disks |
If hospitals can ban smoking as bad for your health, why can't they ban fast food? | Well, in many cases they do restrict stuff like that, but it's impossible to catch everything. In any event, the comparison isn't a good one, because a patient eating food that's not good for them doesn't harm the people around them in the way smoking does. There's a big difference between making yourself sick and maki... |
Could I gain resistance to my nut allergy if I ate small bits of almonds, slowly increasing how much I ate on a routine? | I think that's a question best answered by your doctor, and not random people with questionable google search skills. As you already know, people with strong allergies can have fatal reactions to the allergy. Edit: There are people who can get an allergic reaction to the airborne peanut dust from someone else eating pe... |
How did mass murderers express themselves before guns existed? | There were lots of axe murders 100 years ago. Most households had axes so they were a weapon of convenience.

How does Chrome track me more than Firefox? | chrome is made by google which makes money by selling ads. The more they know about you, the more they can show you targeted ads.

How does a city benefit from having your car towed by a private company? | Straight ELI5- because it's cheaper for the town to let someone make money off towing with their own trucks and lots and get someone all of the associated fees than it is for the town to buy trucks and hire public employees to do the same thing. Plus, those contracts are lucrative and help politicians stay in power. |
How come my car or house doesn't become foggy when the windows are left open? | To get that fog on the glass, you have to have cold air on one side, and warm air with some humidity on the other side.

Planets and Orbit. How do planets and objects in space orbit things without one falling towards another? | > but wouldn't the speed of orbit have to be absolutely perfect so the object wouldn't float away or get sucked in towards the other object? Yes, it would. The trick is that the required speed *changes* as the distance between the objects changes, so orbits can self-correct for minor variations. |
What happens after someone posts their bail? Are they off the hook? What happens after? | Posting bail just means that they don't need to stay in jail waiting until their trial.

When they attend the trial, the money is refunded to the person who paid it. If the person runs a... |
Why are traffic circles/roundabouts so rare in the United States? | It's largely cultural rather than practical.

Why do we have to be called regular names when there are so many possible names? | Because most parents don't really want to set their kids up for years of ridicule. You just know if a kid has a name like @ or # or 123, they're probably going to be bullied. And the system wants to protect against the 0.1% who don't give a shit about their child's welfare. And just want to give their kid a ridiculous ... |
Why my monitor refresh rates are alwys 24, 30, 59, 60, 144 and 165? What's special about these numbers? | To answer that, we have to go way back to the early days of electronic television. CRTs don't use pixels like modern displays do, they have lines. To make an image, you rapidly scan an electron gun back and forth, line by line. Phosphors on the screen light up when electrons hit them. To save on transmission bandwidth ... |
Why is it considered bad to crack my knuckles? | It's not, that's just an old wives take that it will cause arthritis. It will not.

Why do humans crave a happy ending in movies? | It's not humans. It's mainly Americans. If you watch foreign films, they have realistic endings. |
- OkCupid's matching percentages. | The sex and relationship questions don't count towards the friendship count, clearly. So you might rate really high with someone as a "match" because your sex and relationship questions align really well, but you're lower on "friend" match because the rest of your questions don't align so well. Same reason it can go th... |

What constitutes gas prices? When one company sets a specific price, why would a nearby company offer the same price and not a cheaper rate? | I am guessing you are talking about individual gas stations and not major corporations like Exxon and bp. If that is the case, the reason the prices are usually the same at every street corner is that the retailers don't make a lot of money on a gallon of gas. Some may only make a penny or two per gallon. The retailer ... |
What's the evolutionary reason why dogs wag their tails? What purpose does it serve? | This is such a fascinating topic!! Dogs wag their tails to communicate! There are hundreds of different wags :).

I learned this in a science documentary .In addition to communication as already pointed out, dog... |
Why don't we eat dinner in the morning? | If you worked on a farm in the old days your breakfast would often be as large as supper.

a city ordinance here where I live about sidewalks | 2.

How much water do I add to a gallon of whole milk to make it either 2%, 1% or skim milk. Could I do it just by adding water? | No, but if you really wanted to, you could add skim milk to whole milk to make 1 and 2%.

How do flea soaps kill fleas and why aren't they working for my dog? | Flea shampoos are basically watered down insecticides.
