Why does time asleep feel the exact same whether it's four or eight or ten hours? | I believe it has something to do with the fact that you are not conciscious when asleep, and thus any kind of recollection of elapsed time is beyond what you're brain had been doing while asleep. |
why we can secure banking/investment accts online but we can't secure voting | The requirements are different. Most importantly, banking information needs to be tied to the person making the transaction. If any inconsistencies come up they need to be able to make sure they have enough identification information to trace the transactions back to the person who made them. This is exactly the opposi... |
If Stephen Colbert is so marketable and millions of people watch Jimmy Fallon clips on YouTube, then why don't the networks move their shows to prime time? | these shows win against nothing. would people tune in every night when its up against football, voice, ncis, ect ect? I think they would struggle to garner as many viewers in primetime.Consider the demographics of the viewership throughout the day. Who is watching at what times, what content they are consuming, and imp... |
How is that the colors we see organize into a repetitive pattern (ROYGBIVROY...) while their physical wavelengths are linear (390-700nm)? | The issue is wavelength doesn't define color. Photons can be any single wavelength, but our eyes sense the number of red, blue and green photons , so a single wavelength light will be one color, such as red, green or blue, that doesn't cover what you get when you have two different wavelengths at the same time. So Red ... |
Why can we see the xenon atoms in the IBM logo but not the atoms of the surface they're on? | For the same reason that you can't clearly see objects far behind the subject of a photograph. The background is not in focus. That is a simplified explanation, but basically still true. |
What would happen to the United States if China called the debt to be paid in full within 12 months? | the debt is in bonds. which have a set maturity schedule. the bond holder doesn't get to dictate the terms. only the bond creator does.1. they can't. it doesn't work like that. my mortgage company can't say "ok pay is everything tomorrow or we're taking your house". China can't do that either with the bonds they 've pu... |
What exactly happens to your debt when you die. Who is left unpaid? | All assets are usually frozen. The executor to the estate that is assigned by the state must, by law, pay off all debt before any inheritance is given out. If no money or assets are left in the estate, the unpaid folks are out of luck !In the US, creditors get first dibs at your qualified assets and then what's left is... |
Why hasn't NSA's "Prism" database been hacked? | A common feature of secure cross network scenarios is a 'data diode' which literally only allows data to pass on one direction. So even if some hacky malware does manage to get through to the secure system there is absolutely no way for it to send anything back.Systems like this are infiltrated from time to time. Howev... |
What would happen to the human body if it got exposed to the extreme pressures of the deep ocean? | rapid compression. if I had to guess and this is a guess, your body would quickly fill less tightly filled spaces within itself. A little backstory on that: If I recall correctly, they put a skeleton and some pig intestines/parts into an old timey diving suit. I believe they worked by pumping air into the suit, making ... |
. How does a knife cut through stuff | Every material has some amount of stress it can absorb before it gives way. Knives create a lot of stress by taking the force you apply and putting it in a very small surface area.Imagine sticking your hand in a bag with little stones or beads or dried beans etc. Like Amélie Poulain in that famous movie. Your hand push... |
Why do parents need to force their children to eat? | It's not about forcing them to eat. It about forcing them to ready right. Left up to children they will eat only candy and snacks. That's why parents want their kids to eat all their actual food on their plate before letting them go and eating dessert. The fact that some parents over proportion is unrelated. |
why does it sting when I put my contacts in if I haven't slept much /well? | Eye gunk is kinda floating around our eyes while we sleep. When we first wake up, it takes some time/binking for that to go into the corners of our eyes which we end up wiping away. Putting contacts in shortly after waking up, this stuff gets stuck behind the contacts and irritates the eyes Actually I have no idea why ... |
What does the three-body problem mean? | It's just an interaction involving three objects. The Earth orbiting the sun is a two-body problem. But if we lived in a binary star system, it would be a three-body problem. Two suns and a planet all orbiting their collective center of mass. The third body adds significant complications to the mathematics involved wit... |
Chapter 11 bankruptcy. How do companies stay in business and recover when they have no money? | Chapter 11 and chapter 7 are very different. Chapter 7 is game over, sell off everything, pay whatever debts you can from the sale of assets. Chapter 11 might be a temporary crunch. For example, an oil company in Texas has sold 1 billion dollars of oil to Japan. It takes 1 month for the super tanker to go from Houston ... |
Why does Israel continue to build/expand settlements in Palestinian lands despite international condemnation? | Cause it does not care. It gets the USA to veto any action against it at the UN. The P5 countries: US/RUSSIA/CHINA/UK/FRANCE can put a magic veto on any action they don't like against a country they support. So the UN has really no power at all, just puppet bullshit and more money wasting. The are also the biggest weap... |
How do wild animals know to not drink salt water? | it doesn't taste as good as fresh water. that's the same reason you wouldn't drink it if no one taught you.Ever took a big gulp of salt water while swimming.

If a women drugs and rapes a man then becomes pregnant, can she be forced to undergo an abortion? | Of course not. Why would you think this?', "The state cannot force a medical procedure like this. Abortion is only legal because of a woman's right to privacy and control over her own body.No. while she committed a crime and should be punished for that, giving up her bodily autonomy is nog part of that punishment. It w... |
What it would take to shut down the internet in the US | Every country has an equivalent of the UKs peering points provided by "telehouse" and "telecity". This is where Internet providers connect to each other, and to international carriers who in turn connect to other Internet providers. The US will likely have many of these, so in order to stop all Internet traffic from th... |
How does gas compression work? Highschool chemistry taught me that various states of matter are the same thing just molecularly tighter. Why is a compressed gas not just liquid? | Super compressed gas *does* become a liquid for most gasses . Compressing gasses brings the molecules closer together, but most gasses need to be compressed quite a bit before they actually transition to a liquid phase. Check out "phase diagrams" when you get a chance, they show the combinations of temperature and pres... |
How does the box office work? For example Interstellar cost 165m to make but it only grossed 173m. How in the world does a cast get paid with 8m? | Also worth noting that the profits from a movie don't end after a month of release. DVD sales, rentals, licensing agreements with streaming services etc all create revenue after the initial release of a movie.Salaries are included in the cost of the movie.8m might not seem like a massive profit. But think of it this wa... |
If your eyes don't have pain receptors, why does it hurt to look at the sun? | It is incorrect to suggest eyes don't have pain receptors. Some structures in the eye can be among the most sensitive to pain. The retina itself may not react to damage, but there are cells in it which are not used in vision. Instead, it appears some of these cells function to stimulate the trigeminal nerve, creating t... |
If I drink half of a Five Hour Energy, will I have half the energy for five hours or the "full" amount of energy for 2.5 hours? | There are multiple active ingredients in the stuff. Each of them has a curve that initially goes up relatively quickly and then fades slowly as your body processes it. If you take half, the strength of those curves cut, but they are not squashed in the time dimension. That said, it takes a lot longer than 5 hours for i... |
how does a thermal explosion cause a human to get knocked back, as often seen in action movies? | Movies aren't always representative of real life. Action movies even less so. Of course, it's possible for an explosion to knock people back. Because of the rapidity with which explosion take place, they almost always create a shock wave. The problem with being knocked back with the shockwave from a thermal explosion, ... |
What goes into making a music video? Can JT just ask Scarlett Johansson to make-out with him on camera? | As SAG actors, they are required to be paid for the production and usage, and as a big celebrity Johansson's agent surely negotiated a huge sum for her performance. The role of the actual musician in making the music video might be pretty minimal. The concept of the actual video primarily comes from the director. In th... |
How do police and military forces decide which puppies will become members of their team? | I believe they pick specific breeds from the start and train them all, only to give up the really ineffective ones. |
Why are metals like bronze harder than the metals used to create them. | It has to do with the different phases that form in alloys. Basically two materials form a matrix that creates a hybrid grain structure that is stronger than the homogeneous materials themselves. It is a bit complex, but think about it like concrete. Concrete is really made up of sand, pebbles, and rocks. Each on their... |
if we Americans strive to separate church and state, why are so many polling locations in churches? | Why cant they be?

What is making the prices of houses in the UK so high? Is there any hope of fixing this issue? | There are a finite number of houses and a finite amount of space. So as population grows and more and more people want houses prices rise. There is no solution save a good plague or a good war. Need to get rid of the bodies or acquire more landAs Lokiorin said there is limited space but you can also talk about the psyc... |
how does "old faithful" erupt so consistently | [It doesn't], at least, not anymore. The 1983 Borah Peak earthquake set the schedule off balance, and another in 1998 really changed things up. Geysers are fed by underground rivers that lie above a pool of magma. After an eruption, the water begins to fill back up and the pressure increases. Pressure causes the water ... |
why do our eyes/brains struggle to figure out how many numbers/letters are in something when one repeats it self vs when all are different (12333332 vs 60292813) | This is because it is easier for the human brain to count different numbers since you can know at which number you are looking at .When you have to deal with a repeatitive number, you "have" doubts whether you skipped or count twice a number , so you instictively start take more time to make sure you read the number co... |
Why do Black Lives Matter protesters only show up for police-involved shootings? Why are black-on-black shootings ignored? | The protesters aren't there just because people are dying or because they hate "shootings". Black lives matter is about a particular issue - injustice at the hands of the people / systems that are designed to protect us all equally. You might as well be asking why the same people aren't also showing up for events about... |
Beer and rate of consumption... | 2 a day would be healthier. When you drink 14 at once, your body is going to struggle to deal with it at once, you're taxing your system a lot more. While a couple a day, your liver can deal with that without a bunch of backlog, you're not going to be sick, not going to be dehydrated etc |
Supreme Court decision on Citizens United | To understand *Citizens United*, we actually have to go back to some earlier cases to get the context. The first concept to understand here is that the line of cases beginning with *Buckley v. Valeo* and continued in *Citizens United* basically said "the ability to spend money to support a given ideological view is par... |
When momentarily walking past fumes (exhaust, tar, etc) is it better to breathe normally or to restrict your breathing for a short period (thus reducing oxygen intake)? | Hold it. There isn't harm in short periods without breathing, so the down side is nil. The stuff you're breathing probably isn't going to hurt you if it's just a whiff, but there's more potential harm from it than from held breath. |
How is the Universe expanding if gravity pulls things together? | Wouldn't physicists like to know. But seriously, they dont know. At this point, all we have are some theories. Mainly, dark energy. Basically an unknown, undetectable force that pushes on everything in the universe. Locally, its not strong enough to overcome gravity, which is why stars, planets, orbits, galaxies, etc. ... |
How does the placebo effect actually work? | You have substances in your body that are chemically very similar to the drugs that are prescribed by physicians. The reason drugs work is because we have receptors that drugs may biochemically bond with. In the case of placebo, it's believed that the suggestion actually activates the body to create and mobilise the na... |
How do those 90's "Magic Eye" pictures work? | The proper name is "single-image random dot stereogram" It's tricky, and describing it without drawing diagrams is a little hard, but I'll try: Imagine a 3-D model on a table. There's a piece of glass halfway between your eyes and the model. Paint a random dot of color on the glass near the middle. Look at that dot wit... |
Why do we find "sweet" things so pleasurable? Even other animals really seem to enjoy sweet things. | Sweet implies calories, and animals need calories to survive. Animals evolved not knowing where their next meal was coming from, so it benefits them to eat as many calories as possible while they can. By making calories pleasurable, it creates a desire to eat them. |
Why can't electrons have a defined position? | I suspect you have an image in your mind of electrons moving around in space like physical objects such as ping-pong balls. So you 'd be right in asking "how can't that object have a defined position?". But there are other ways of thinking about electrons. Imagine I yell "I am an electron!" from across the room. Now, w... |
how do multilane highways reduce traffic if they merge to fewer lanes without oppurtunity to turn off? | They alow the people driving at a faster rate to get ahead of those that are driving at a slower rate and causing the traffic to collect behind them.They don't, at least not at the particular point. The idea is that enough people have already turned off that you don't need so many lanes anymore. It is a question of bal... |
Canned meat not needing refrigeration? | Part of the canning process is heating the cans after they are sealed. The heat kills any bacteria present in the contents, and the sealed can prevents any new bacteria from getting in.

Why is North Korea so secluded? | Ok. So here's the "non-loaded-rhetoric" version. The isolation in North Korea has two aspects. The ideological aspect, and the "actually useful" aspect. THe ideological aspect deals with the ruling political philosophy of the nation, Juche. Juche is, in simple terms, the idea of self-reliance. And not the "'murican" se... |
Why do the members of the Whitehouse press pool yell out questions to the President after they have been told that no questions will be taken. | That's what you do as a journalist, ask questions. You wouldn't be doing your job if you kept quiet. It's pretty normal in all settings like this. There's a big difference between "we asked, and he didn't want to answer" and not asking at all. I don't know if it's ever worked in a presidential press conference, but it ... |
Why do we use the "Qwerty" keyboard? | You can wiki for more. The basic story is that English has a number of common letter pairs. On old typewriters these letter pairs were often so close together that the arms could swing in and jam if the operator was too quick. So the Qwerty board was developed. It breaks up the common letter pairs so that jams happen l... |
How do companies like EB games and Gamestop make money when the game/console creators sell the game online for the same price? | Source: I was an assistant manager at Gamestop, and I worked there from 2011-2014. A very large majority of their money comes from used games. We paid $54 for every $60 new game we sold. We only made about $25 off of new consoles. The only thing that keeps them afloat is used games. We would make $35 off a used game th... |

Why there is such a variance in the human phenotype, as compared to other species? | the same reason asian people tend to look the same to a white person. they're so different from us that we overlook the subtle differences that are in fact obvious to someone or some animal of the same species. e.g. they do vary, you just don't notice it because you aren't an elephant. the point about human evolution t... |
How exactly did Edward Snowden get hold of all the documents he leaked? | From [this article] : "As a system administrator, Snowden was allowed to look at any file he wanted, and his actions were largely unaudited. “At certain levels, you are the audit,” said an intelligence official.

If poverty is so bad in an area like in ghettos or in Africa. Why do people so readily continue having children only to be born in to hardship? | You think of them as another mouth to feed because you're a middle class guy in a nation with child labor laws.

Or you might simply be uneducated with no access to ... |

Is Generalized Anxiety Disorder something you're born with, or are there life-triggers that set it off? Can you ever truly be "cured" of it? | TLDR: We don't know. Since brain science is a young field and not much is well understood yet, psychiatry mostly aims towards addressing mental illnesses pragmatically, rather than trying to achieve a deep understanding of mental illnesses, with a goal of eliminating symptoms. In this way, it is firmly within the realm... |
Do smarter brains use more energy or do they just use it better? How? | Some studies have found that when people are not very good at a particular task, they exert more mental effort and use more glucose and that, likewise, the more skilled you are, the more efficient your brain is and the less glucose you need. Complicating matters, at least one study suggests the opposite—that more skill... |

At what point is a virally infected person no longer considered a "carrier"? How can we become immune to certain things without carrying/spreading the sickness ? | I'm not sure about the first part but I can answer the second part. The answer is vaccines.

How are "generations" measured? Where is the cut off? | A "generation" is a vague unit of time, so it depends on the context. In genealogical or biological terms, it is strictly the parent/child measurement, so yes, you would be in the same generation as your cousin, since you share the same percentage of genes of your grandparents. In a sociological context, "generations" ... |

how do people graduate/finish school early | They don't complete 12 years of school, that's how. They do some school, and everyone involved agrees it would be a waste of time to have them sit through the same stuff as everyone else, so they skip them past several grades. 16 isn't really that crazy, I graduated high school at 17, and I went through every grade. So... |

how does CPR help someone who has been drowning? | I'm not a doctor, just a paramedic, but this is my basic understanding of how it works. Not all drowning victim have water in their lungs due to involuntary laryngospasm. But either way, the lack of oxygen to the brain and other organs causes unresponsiveness and cardiac arrest. Once the person has been removed from th... |
why it takes less time to fly from west to east compared to flying from east to west | In really high altitudes there is moving air called "Jetstreams.

Why do most live performers remove their in ear moniters when they perform? If it affects their performance, why do they wear it in the first place? | > As a professional musician for over a decade, the simple answer is this: In-ear monitors are excellent for keeping a fine tuned ear on what is being played, hearing click tracks, and getting cues.

How can people not get source code for a game even though they have the exe and files | The .Exe just contains the compiled code, which is pretty hard to reverse engineer into source code.

The problem with reverse engineering compiled code is tha... |
How do forensics assess whether someone was raped before or after being killed? | Rape tends to damage tissue a lot. If alive when damage is inflicted, the body immediately reacts to the damage in various ways, causing bruises.

The choice for the region in which th... |
Knockouts and concussions, what and why does it happen, and what is the difference? | I am a high school level soccer coach in Colorado, which means I am required to take a concussion course every year that I am active, which for me is 3 years.

What is the joke behind "Runway 37" | Runway numbers only go from 1-36. They are basically numbered for their magnetic heading divided by 10. _URL_0_', "Found it! Runways are numbered by the compass direction they face, rounded to the nearest ten, with the last digit dropped. So a runway pointing to 311 degrees would be Runway 31. Runway 37 would be pointi... |
Why do scratched CD's skip while playing in my car but don't skip when playing on my laptop? | Some players are better than others at ignoring the scratches.

How can Valve get away with cutting prices as much as 70% on Steam for mostly games they didn't even make? Are external game companies not getting really pissed off from missed profits? | Valve has to clear such sales with the publishers who are making the money from those sales.

I am going to make more money despite the price being lower. Valve knows this wor... |
Why haven't we seen any 90s Nick Game Shows (Double Dare, Legends of the Hidden Temple, Nick Arcade) rereleased? Legality issues? | You don't normally see *any* game shows rereleased.

I don't thi... |
If you drain ground beef after you brown it for something like spaghetti, what is the difference between using a ground beef with more fat like 80/20 vs 90/10? | If you are draining off the grease the major difference is that you will have less meat. I do not think it is the full 10% of weight difference but it can be fairly close if you cook it long enough to render out most of the fatSome of the fat is still inside the meat. It also affects how the meat cooks, since the oil b... |
How does the brain decide what little stupid things to remember, like what someone said or a song you heard once? | it's mostly based on the situation you're in. even if you just barely notice a balloon in the furthest corner of your view your brain could go like 'you member the time, you had that stupid little baby balloon? i member' |

Why are so many rap/hiphop songs still about how good the rapper is? | Well, don't forget that rap has evolved to something of an art form.

How do companies like Amazon pick their "random winners" when the submissions are made online? | Well it could vary from system to system but all randomness in computers is actually pseudo-random.
