Why do we feel so embarrassed when en erotic scene appears on a movie we are watching with our parents? | It has something to do with our natural aversion to incest, which as you know is not good for us, genetically speaking. So, erotic scenes arouse us. We don't want to be aroused around our parents, and vice-versa, because it's like you are being aroused by your parents in a way, since they're the only actual people arou... |
has Neil deGrasse Tyson contributed anything significant to science? | NDT is generally credited as leading the decision to remove Pluto's planetary status. So I guess you could say he effectively removed a planet from our solar system. |

Can you have a child with two fathers? | You couldn't cross two sperm cells. Egg cells have all the machinery for creating an embryo. It's not theoretically impossible, though. The way, in theory, to do it would be to make stem cells from Dad-1, and then differentiate those stem cells into egg cells, and then fertilize that egg with sperm from Dad-2. As long ... |
Why does remote starting your car for 5-10 minutes waste so much gas? | Idling is wasteful because the engine is running and you're not going anywhere. You're getting zero miles per gallon. Giving the benefit of the doubt, that's a half hour a week of a car doing nothing. If you want to save some money and not freeze your butt off in the morning, they make heated seat covers that plug into... |
Why do life forms of larger mass require less energy to survive than smaller life forms? | Your question is generally incorrect in its assumption. Larger animals expend, and hence require, more energy than smaller animals. However, there are a variety of differences in metabolic systems between organisms, some of which are more or less conservative than others, such as ectothermy, part of a range of adaptati... |
Why do psychopaths and killers in general take trophies? | To relive the thrill of the kill. It might also have a sexual motive. If you're turned on by the murder, as seems to be the case for many serial killers, taking an item to remind you of the event can be used as an aid in the same way that someone that isn't quite as disturbed might use a pair of panties. |
How come I haven't been caught for piracy? Am I more likely to be caught pirating a movie or software rather than a song? | probably because you haven't pirated enough to be on MPAA's radar. or you've been lucky. considering that probably less than a couple of hundred people have ever dealt with a MPAA notice out of .tens of millions of piraters.Not sure this is entirely true, but I 've been told that they look for uploads rather than downl... |
Why do doctors have to work extremely long shifts, even tough fatigue could be fatal in their job? | In Britain the doctors are striking against it. While I agree with them what would be the successful outcome of this? Surely they are overworked because there aren't enough of them?", 'I always thought it was because working in a hospital in that kind of position bestows so much urgency and responsibility that they bas... |
Why do people delete highly successful posts and comments? | In addition to /u/Phage0070's points, sometimes people get lots of attention for stupid jokes or posts that they're not particularly proud of, so they delete them. Happened to me before, for a while my 2nd highest voted comment was a lame comment about some mildly NSFW link, and I decided that I wanted this reddit acco... |
Is it possible for one arm to be visibly stronger than the other? | [I'd say yes.] In all seriousness though. Yes, I had a friend growing up who had a stroke as a kid and lost full use of his right arm. Since he does everything with his left, his left arm looks normal, and his right arm looks atrophied. Although that probably isn't what you were asking. |
why can't Buffalo, NY just dump the 32tons of removed snow BACK into Lake Erie? | They can and they will. They did it for blizzard of '77. Once the places they're using now fill up, they'll put it in the lake. |
Why are we scared of the dark? | Thousands and thousands of years ago, some of our early ancestors happened to be afraid of the dark. Some of them weren't. The ones that weren't had a bit of a tendency to get eaten. Or fall from heights. Or other unfortunate things that can be harmful to your health that happen when you can't see. Not all of them, min... |
Why don't they use Hawkeye on every point in tennis, to avoid human error? | Multiple reasons: First, cost. Many smaller tournaments can't afford to have hawkeye installed, and even the Grand Slams and Masters 1000 tournaments only use it on their larger courts due to the cost of installing them everywhere. Second, time. The vast majority of calls are made correctly and *immediately* by the ump... |
When looking at a glass, why are we able to choose between seeing our reflection and seeing through it. | Your eye is able to focus on different objects and varying lengths away. It is akin to changing the aperture on a camera that focuses on one point but has everything in the background blurry. Let's say your facing a window and you are standing 5 meters away from it. 15 meters past the window is a trash can. You will se... |
-18: why maths is worth learning | I think people are missing the point here. So here is my ELI5 answer: Its not learning the formulas or actual math equations that the study of basic math helps with. Many people won't use those in everyday life. But that's not why you learn it. You learn it to figure out how to solve problems. You learn to think in log... |
Why do we get a "someone's watching me" feeling when someone is watching us, despite not knowing for sure that we're being watched? | Our brain picks up on way more things that we are consciously aware of. If our brains didn't filter out information, then we'd be under constant bombardment and unable to do anything. While you may not consciously be aware that someone is watching you, chances are that you may have seen them watching you in your periph... |
Why do people throw up from high intensity exercises? | Apparently the people who have responded to this question don't even lift. I'm an experienced lifter and after very intense workouts , I am sometimes on the verge of puking/passing out. I have in fact puked a few times. In that case, it's not related to heat exhaustion. It turns out that the the nausea is related to yo... |
The whole Netflix ISP thing. | nothing to worry about, it's about a piece of US legislation, doesnt apply to the UK providers.Verizon found a way to get around net neutrality and be able to throttle access to Netflix, unless Netflix paid Verizon to allow them through If this did happen Netflix would vigorously protest and encourage our members to de... |
The phrase "Liquor before beer, you're in the clear. Beer before liqour, never been sicker". | The order doesn't matter. It is just a saying. A drunken theory of sorts. You might say that starting with liquor will better control your intake. When it comes down to it - drink a bunch of any alcohol, in any order, and you will probably get sick. |
Why did petting animals become a thing? | I vaguely recall hearing that dogs generally do not like being pet on the head, because to them it is a sign of ownership/domination. I'm not sure how true this is. However, since reading this, I've noticed that my does seem to visibly flinch or otherwise brace herself when she sees me raise my hands, particularly if t... |
What is the difference between a bad headache and a migraine? | As a 17-year migraine sufferer, this sums it up pretty well:_URL_2_ The only thing I would add is that I've honestly never thought about taking my own life, but I've had a migraine so bad that I didn't want to live. I just wanted to stop breathing an cease to exist. |
Given the vastness of the US borders, how do they keep it in any way secure? | They don't. The southern US border is vastly unsecured and people and drugs can quite literally be walked across it. The United States relies on the annual migration of immigrant labor to harvest the vast majority of its crops and there is a large immigrant population in the country so there is very serious domestic po... |
Existentialism....I don't get it! | A short story by Albert Camus might help , although he disputed that association. I think he was mistaken, but it doesn't matter. |
Why is SpaceX having so much trouble with their launches, especially when they're being assisted by NASA, who have been doing this sort of thing successfully for decades? | > they're being assisted by NASA, who have been doing this sort of thing successfully for decades You're reasoning is incorrect, NASA has never successfully done this. NASA has sent one-off rockets into space, but they have never made a reusable rocket which can land back on Earth, which is what SpaceX is trying to per... |
If The Hubble Telescope's optics can focus on distant galaxies, AND can focus on a local body like Jupiter, why can't it see Pluto clearly? | Pluto is incredibly small and much further away and doesn't reflect a whole lot of light for the telescope to pick up.

why do cars get the same gas mileage as they did 20 years ago? | My current car does 50 mpg without blinking. If id gone for the smaller engine option it would be doing 70. And that's just plain old 2L vs 1.6 L mid range cars. If you want to get massive engines then there's only so much you can do. However claiming that fuel efficiency hasn't increased is a massive misrepresentation... |
Why do Common Core hated so much by some? | A lot of people are not interested in learning a new way to do math. They already know one way and it works for them. Common core makes it difficult for parents to help their children because the new way is different and the parents don't understand it. For the kids it is no big deal, until they ask for help from their... |
How do people hack Console videogames when they don't have the ability to mod like PC's | Basically, the only difference between a console and a PC is that on consoles the manufacturers can choose which software can and cannot be installed.

If bananas don't naturally reproduce and are all the result of cloning by humans, how are there different types of bananas? | Because there are hundreds of species of bananas in the world, just the ones we eat are identical. The bananas our grandparents grew up with were a different species all entirely called the Gros Michel, which is where the flavor of banana in candy that we say doesn't taste anything like bananas at all comes from. It do... |
What exactly happens to Gandolf during the time he progresses from Gandolf the Grey to Gandolf the White? | For a second I thought he was referring to a character from another book I didn't know about. |
Why are chemotherapy medications and other specialty therapeutics so expensive? | In general, drugs are expensive because of the research and development, as well as the company wanting to make as much money to recoup the costs before their patent runs out. An analogy would be a newest Call of Duty game. It costs $60 . $60 isn't the cost of the materials. The box may costs $2, the CD itself a few ce... |
If gas prices are pretty much guaranteed to go up in the summer, wouldn't it be obvious to buy stock in oil companies? Or are oil stocks just based on speculation? | BTW, gasoline evaporates faster as the temperature rises with the formulation that they use during the winter, so the formula is changed during the summer to combat this. It's a more expensive formula. |

Creativity is ... |

- Why are people occupying Wall Street? | Basically they want people to be held responsible for the actions they have done, the oozing corruption to be stopped and for financial reforms to be put in place so that peoples financial security isn't completely destroyed because some fuckhead in a suit on ten million a year has no idea what he's doing. The protests... |

What are the odds of a blue eyed mother and brown eyed father having three blueasy eyed children? | If the father had one set of blue eye genes, it's possible. I believe.

How do I tell if a diamond is real? | Go to a jeweler and ask! I learned everything I know about shiny rocks by sitting at a counter and yakking with the jeweler about cuts and grades and inclusions and colors and such while my ex fawned over rocks.

Why is slope rise over run? | It's kind of intuitive, don't you think? In a rise-over-run calculation, a slope of zero is flat and an incline has a positive slope, and a vertical line which has an infinite slope. A decline has a negative slope. If you were climbing a hill, for example, and in many other real-world situations, those numbers make the... |
Why do we recognize that mirrors are "silver" when they appear to be the exact same color as what they are reflecting? | You can see your reflection in a shiny car, right? How about the tv screen when it's off? We can recognize the colors of those items, even though they are reflective, and mirrors are no different. Reflective surfaces can be any color. Mirrors are simply a neutral color that better reproduce the colors one would see if ... |
Why does heating my house take no more then an hour, but using the air conditioner to cool down my house takes hours? | Furnaces have more heating power than air conditioners have cooling power. It never really gets above 110, so an air conditioner only has to cool it down about 40 degrees. In some northern climates it can get down to 40 below, so a furnace has to heat it up over a hundred degrees. A car cools down fast because that's d... |
How do flashing lights cause epileptic fits? Would high intensity bursts of any other types of sensory information do the same? | I don't really know the specifics of epilepsy, but other types of sensory information can trigger seizures.

Why was Nixon impeached for wiretapping, but the NSA revelations have not led to serious impeachment calls for Obama and everyone else complicit in this? | He wasn't impeached, he resigned. He was going to be impeached not for wiretapping necessarily, but for ordering illegal acts and covering them up.

Why do people cover their mouths with their hands when surprised, shy etc? | I wonder if it's an instinctive reaction to not making a sound. When our hunter gatherer ancestors were running around, suddenly shouting or making noises when startled in the face of a predator or pray probably didn't increases their chances. As for being shy it's not so much the mouth but the face to hide blushes may... |
Why data measured in both metric and binary? | They use the metric / SI definition because that's quite literally what a giga- anything is. 1 GHz = 10^9 Hz 1 Gg = 10^9 g 1 Gm = 10^9 m etc. You're using a prefix which has the same meaning in every single other example of it being used, so why should a gigabyte be any different? What you'd call a gigabyte in computin... |
How will infrastructure change as electric vehicles become more prevalent? | If retail stores were smart, they'd put them in thier parking lot.

It's a vicious cycle. |
Why is the new King of Saudi Arabia the half-brother of the old one and not one of his sons? | Titles passing from father to son is known as primogeniture, but primogeniture isn't always the system in use; primogeniture was the standard of Europe in the late middle ages and on.

How do famous people/world leaders get each others phone numbers? | Apparently the Egyptian President did simply call Trump Tower.

As for whether they are who they say they are, there have been occasion... |
Wouldn't NSA help investigate crimes/track criminals more efficiently? | If you measure the security of your homeland in terms of lives lost, consider this. The fatality rate from terrorism in the U.S., averaged over the 19 years 1985-2003, was [0.44 deaths] per *million* people.

Why are roof shingles so small? | Shingles are attached to plywood , which is attached to proper structural beams.

What exactly makes CANDU reactors more safe than other nuclear reactors? | They are mechanically designed to fail closed. Excess heat causes failure in the holding rods, which limits pathways for reaction. It also operates under low pressure, which makes it less likely to eject fuel rods in a failure.

How did the Dutch take land from the sea? | There's a couple of different ways, but the most iconic one is the making of polders. The basic idea is quite simple: you select a lake, you make a dyke around the bit you want to turn into a polder, and you start pumping out the water. Now most of the water won't be able to flow back, because of the dyke and you've go... |
Why is pausing a video represented by two vertical bars? | It all has to do with how tape moves past the tape head. Play is an arrow to the right because that's the direction the tape moves in order to play. Fast forward uses two arrows because the tape is moving faster. Reverse and rewind are similar, but in the opposite direction. Stop is a square because the tape isn't movi... |
Why does the UK only partially use the Metric system? | I believe it is due to successive governments being afraid to upset voters.The Daily Mail brigade would have a field-day. Completing the transfer to all-metric would also need a lot of money to replace or alter every speed limit sign and road sign showing distances, which 'we' have decided we don't have the money for.S... |
- in the US, why do we have a jury selection process? | The idea is to get a jury of the defendant's peers. Suppose you are a minority defendant. A random selection could wind up with all white, upper-class jurors.

Why did Kim Jong Il make so many trips to China and seemed to get along with its leaders when they have different ideologies? | Firstly your assumption that either party actually lives by their espoused political ideologies, is a joke.

If we can clone a sheep, why don't we just clone endangered animals to save them from extinction? | At it's simplest, animals aren't typically just going extinct for no reason. There are causes, like habitat destruction. Making more animals does not solve the problem. There are other issues related to cloning, like the need for a surrogate to carry the offspring, maintaining genetic diversity, and the fact that it's ... |
if universal health care was made legal in the US, what would happen to the health insurance companies and their employees? | In Australia we've got both a universal public health system, and a private one.

Launch was aborted to investigate... |
Why doesn't the sport of boxing sign an ESPN TV contract and stop doing PPV? | The singular nature of boxing makes it harder for the promoters and the fighters to get their fair share of the money. Unlike football or basketball there isn't a regular enough schedule to determine who should get a cut. |
If the senate can just reject the President's veto, what's the point in giving him the ability to veto things? | A two-thirds majority is required in both the Senate *and* the House to override a presidential veto, as opposed to the simple 50% majority required to advance legislation to the President's desk. Congress is very rarely so unanimous. The presidential veto is a general check against the legislature, but the override ex... |

Why can't billion dollar companies such as Facebook or Skype produce quality mobile applications when smaller developers can produce high quality applications with much less manpower/funding? | Stripped bare: If you're not paying for an App, you are not the consumer, you are the product. Even if you're paying, you're probably still partially the product. Your satisfaction is only of concern if you defect. Smaller developers want you to use them, larger ones want to use you. Choice is yours. |
Why is it recommended to pee on someone who has been stung by jellyfish? | Urine is slightly acidic but, as has been said below, it's really not recommended. It's one of those last-ditch things. You're better off with vinegar or meat tenderizer. Follow-up: I had a company commander tell me that he wouldn't piss on my mouth if my teeth caught fire. So not teeth. |
During the 20 year patent period, does the pharmaceutical companies determine the price of the drug or is it regulated somehow? | It is worth noting that drugs don't actually have 20 years of patent protected sales. Patents must be filed prior to initiation of clinical trials, which can take 8-15 years, and there are means in many countries to partially recoup time spent in trials or waiting for government approval. By the time a drug is approved... |
Is time passing in dreams contiguous with the actual time passing in reality? | From the research I've read, dreams appear to work much the same as our conscious memory. You don't remember every foot of the road you've walked down today, your brain only bothers with remembering the important bits, the highs and lows. Dreams would appear to be just that, just the important bits, like the few moment... |
Why is it possible to imagine something never seen before, but impossible to imagine a color never seen before? | When a blind person visualizes something that they touch, they are able to make an image by exploring the object through touch, or in some cases sounds.

How has thousands of employees of Wells Fargo not been charged with ID theft? | I still don't understand why the employees got fired if they were pressured by management. Anyone care to explain why? |
Why does the "unsubscribe me" button never work on emails? | The thing about laws is they have to be enforced or they don't matter. Enforcing the law on the internet is really hard. If the spam email is coming internationally, or being sent from compromised malware-infected systems within the US, tracking it down and corking it is challenging and time consuming. If anything, cli... |
Why don't NATO and other supranational organizations just go ahead and take out ISIS? What makes it so difficult? | NATO has always been a reluctant partner, perhaps because its members have experienced so much more war on it lands than the US and Canada have, and I suspect NATO is tired after over a decade in Iraq and Afghanistan. Then there's also the problem of military capability: European members of NATO has very little transpo... |
What kind of paperwork is involved in starting an independent nation? | > Are there specific types of documents that need to be drafted and signed to separate from your original country?

Why does the date Jesus was born never change but the date Jesus dies changes every year? | The date of Easter is calculated based on first full moon following the spring equinox.

Why do most predatory animals choose not to eat humans? | Very simple, we're not their typical prey. They don't know what we are. They haven't hunted us before. We're not deer, moose, antelope or tuna. What are we? Attacks are much more likely to be out of territorialism or dominance than preying.
