Why is our fear of embarrassment often greater than our fear of genuine danger? | Humans are social creatures. Embarrassment means you believe you have made yourself look bad in the eyes of others, thus lowering your social standing.

Why do biker gangs typically ride big displacement motorcycles instead of the faster potential getaway/chase crotch rockets? | Running from police or opposing gangs is not part of the plan. In most organized crime groups, crimes such as loansharking, drug production/distribution, money laundering, etc are chosen for a reason-- you can get away with them and make a career out of it.

Is U.S. currency no longer backed by/worth anything tangible? What are the implications of "Fiat" currency? | Yep. Pretty much. There are significant disadvantages to money being backed by a precious metal -- especially if your country doesn't produce much of that metal.

But the US tax code says people can deduct their businesses losses from their personal taxes ... |
How does a wifi signal continue to provide clean data (albeit slower) despite the increase in "static" caused when traveling farther away from it? | Analog signals degrade gradually because they're analog. Digital signals degrade all at once. I.e., either you received the data packet, or you didn't. It takes longer to transfer data on a weak signal because youre sending and receiving incomplete packages, so your device keeps trying until it gets all the chunks thro... |
How do babies have thoughts if they don't have a language? | I am not qualified enough for this question, but I'll try. Language is just a set of pointers. They point to some experience. Language allows us to communicate that experience. Babies don't do that. Thoughts are although not properly defined, somewhat closer to simulation of that experience and what that experience res... |
Why does Apple not build its own manufacturing plants? | Apple doesn't make anything that requires them to build their own cutting edge manufacturing plants. They can just buy parts from other people & send them to Chinese factories for assembly. When you're dealing with something commoditized, like LCDs, mobile semiconductors & electronics assembly, it's far cheaper to cont... |
Leasing a car for 6 months | As far as what a 'good' rate is, you should ask in /r/alaska or /r/Fairbanks . ELI5 is for conceptual answers.

As far as credit goes, this will vary from dealer to dealer. Having ... |
If we sent a team to Mars, why wouldn't they be able to return? | Have you ever gone on a road trip? The kind with toll booths? Well going to mars is a long road trip. And we start with $5. $4.50 is spent on tolls alone getting from earth and into outer space. We spend another $.50 landing on mars. Great, now we're at Mars but we're broke and the car exploded. Guess we are staying th... |

Why do almost all American states have a bicameral legislature like the federal government does? | Lots of countries have bicameral legislatures, and they're not necessarily to do with regional representation. The lower house has the power to propose new laws, while the upper house , House of Lords in the UK, etc.) does not have this power, and may only accept or reject laws proposed by the lower house, or perhaps s... |
Aside from accidents and self-neglect, how do you die from dementia or Alzheimer's disease? | The cause cell death in the brain. For Parkinson's at least, and I'm assuming it's the same for dementia, the problem starts in one area of the brain then progresses from there. As the cell death progresses so does normal functioning. Memory, movement, you name it. Although dementia is strongly associated with memory l... |
How do sites like EZ TV and kick ass torrents not easily get shut down? | My go to torrent site has a report copy right link. Basically send them proof of ownership, and they'll take it down, but chances are that same link is 100+ other places on their sites. Also rules. _URL_0_ isn't hosted in the US SK US laws don't apply to them |
Why does "time fly" when I'm having fun? | There is a saying that a watched pot never boils. It is this concept in reverse. It is simply heightened awareness.

When doing something truly enjoyable time isn't an issue because its passage isn't ... |
How do some drugs, like SSRIs, increase the risk of suicidal thought in patients? | SSRIs tend to improve physical stuff before emotional stuff. It's theorized that making someone more energetic while still depressed can motivate a suicide attempt. There may also be a paradoxical effect, too. You know how some people take medications that are supposed to make them tired but they just feel wired? It's ... |
How does the vacuum in a thermos prevent heat dissipation/loss, but the same does not work for the sun in space? | But it does. If you touch the sun directly it's a lot hotter than if you just stand a bit away with the vacuum of space in between. You see, in a thermos the only way for the heat to escape is if it turns in to heat radiation to cross the vacuum. If the thermos was just solid metal, the heat could travel really easy fr... |
Why haven't we bred crops with weeds yet? | Traditional breeding is limited by genetic compatibility of the plants being bred. Just like I couldn't breed elephants and sparrows, I couldn't really breed wheat and dandelions together. They're just too different. That aside, we could definitely breed for more weed-like traits. Many of our food crops like blackberri... |
Why do we like to listen to bass? Why is it pleasing when DJ drops the bass? | Why is the bass so loud? I can't be the only one!", 'The real question is: Why is the bass so loud?', "Dopamine is stimulated in expectation of payoffs that directly reward us or allow us to set further anticipations.

If there is a supermassive black hole at the centre of our galaxy, why is the centre so bright? | The reason you see the bright spot in the center is that the star density is much higher there. This means there is a much higher density of luminous matter there, and it is hence brighter than the rest of the galaxy. What you are saying about a super massive black hole is correct, but the thing about black holes is th... |
What are the differences between the branches of the US Military? | Hey, the big thing to think here isn't what is different with the branches. You should talk to each of the recruiters once you get the ASVAB test results to see what jobs they can offer you.

Why are the Brussels and Paris attacks so publicized and mourned over when others, like the current Pakistani Bombings, kill more and do more damage? | Speaking from a European perspective - Brussels and Paris are two things: a) They're not considered warzones - Pakistan is both at war, and in the midde of an area from where we commonly hear of wars, so it doesn't register in a lot of people's heads as shocking. Brussels and Paris are considered peaceful, safe areas, ... |
why do we call lions the King of the Jungle when they live in the Savanna? | This has more to do with the etymology of the word 'jungle' than where lions live.Jungle was the British colonial reference to the forests of the Indian sub-continent.

Why the relationship between Russia and the US is so bad. | Ideology. Imagine if you purchase a bunch of candy and sell it to your class at a profit.

You as the candy salesman cant hav... |

How do we get dizzy? | The others are all correct. Here is how my Dad explained it when I was a kid: **ELI5**: Imagine a **glass of wine** - see how I tilt the glass slowly, but the wine level remains flat, parallel to the ground? Now watch as I twirl this wine glass around in a circle! The wine rises up to the sides - it's no longer flat wi... |
Why are all of the planets and belts in our solar system on the same relative axis? | Solar systems naturally flatten out into discs over time due to constant collisions. I can't explain it nearly as well as the video below, though. For some reason ELI5 doesn't seem to like videos that literally answer the exact question you are asking, so hopefully this goes through. [Here is a video on the topic] |
Why do blackheads most commonly occur on the nose? | Usually people wear shirts, some have armpit hair, this prevents dirt getting trapped in pores in that particular location, it doesn't prevent sweat - which is a breeding ground for odor-causing bacteria; so armpits usually smell bad after a long sweat.

Mama, papa, dada, etc. are easy to articulate because they don't involve complicated vocalizations and they are located at points of articulation that are easily seen by infants . The phonemes that are ... |
Why do Humans get aroused watching others having sex? | So I can give an evolutionary reason. It is an advantage for most animals to become sexually aroused to certain cues that indicate a potential mate may be interested in sex. Just like it's important for an animal to get hungry at the sight or smell of food, because it makes the animal likely to direct its behavior towa... |
Why did the Grenfell tower not fall like the WTC? | Multiple reasons: 1. Different structure 2. A Boeing 767 at full weight traveling at ~500 knots didn't slam into it with intent 3.

why do apps need access to so much information? | Orsenfelt gave a good explanation. I would like to expand upon his third point that the app does need the permissions for non-malicious reasons but you are not aware of why. The permissions are very broad in scope. This is necessary so non-technical users can understand what the app they are installing has permission t... |
The problem with "true randomness" | The _URL_0_ explanation probably has very little to do with what you're experiencing. The difference between a pseudo-random number and a truly random number is small enough that you aren't noticing it on your iTunes playlist. In all likelihood, what's actually going on is really just something you're perceiving. Your ... |
The difference between a line of credit and a loan | $1,000 loan: when your loan is approved, you get a check for $1,000. $1,000 line of credit: when you're approved, you get a credit card and can borrow up to $1,000. So, when you get a $1,000 line of credit, you haven't borrowed anything yet, so you don't have to pay anything back yet, until you charge something against... |
Why are buildings in Australia and America not built with sturdier materials, to deal with the regular natural disasters? | First, the US has a lot of wood, so that makes it easy to build with that, and very cheap. [That's part of why the US has likely the largest median home size in the world]. You just don't get as much space as cheap with brick and morter. But more importantly there are a TON of houses in the US, and very few of them act... |
If the evidence for the holocaust can stand by itself, why is it illegal to deny the holocaust in several European countries? | Wait.. Denying the holocaust is illegal??? Are you freakin kidding me? Or denying the holocaust in school teachings or something illegal? If someone wants to sit at home and not believe the holocaust happened, who's to tell them they can't think that? I can understand it not being okay to print history books denying it... |

Why hasn't the Government done anything about the Cult of Scientology? | Now it may be true that its leaders are driving expensive cars and living in mansions, all owned by the church and that's sketchy.

Why are sites displaying "pre-teen modeling" not taken down for child pornography? | Because they're not pornography. Creepy, yes; pornographic, no.

Why are older videos from the early 1900's sped up? | The film used back then had a longer exposure time am many of the cameras that I've seen then we're used were manually driven. Film was pulled slower behind the Lens to expose it properly. When brought up to the standard 24 frames a second most movies are at, it looks sped up.They are not speed up. The thing is that th... |
Why are there sometimes blank power outlets? | I'm no electrician but a quick google search tells me that these are used simply to cover unused switch plate locations. It's cheaper than covering the hole and allows easy access in case you want to use that location in the future. |

Why does one eye force itself close when it’s bright outside? | Spit-balling here, no studies that I'm willing to look for, but I'm nearly done a MSc in genetics and molecular biology, I have had to spend a depressingly large amount of my time learning about evolutionary biology. As an addendum to the physiological response of the eye to light given by Bane_xr, I'll add some specul... |

Couldn't "uninhabitable" planets support types of life that we don't know about? | They are looking for planets with conditions similar to Earth. Space is vast and large. Trying to search every planet is difficult due to time and money. We know conditions on Earth support life. Therefore, we know other planets with conditions like Earth's can support life. Can other conditions support life? Possibly ... |
How do certain MMORPGs without a subscription keep their servers up? | Usually by offering the basics of the game for free, but charging users for premium content or specialty services.

The Lord of the Rings MMORPG offers extra character classes for people willing to pay... |
What is the idea behind what we perceive as reality possibly being a simulation? | 1) All your senses are electrical signals being received by your brain. In theory, those signals can be replicated and your consciousness will not know the difference between real and simulated. 2) Right now, scientists are simulating the universe in supercomputers, however, not down to the atomic level yet! The data i... |
In video game graphics, what exactly are Sprites and Polygons? What are the differences? | polygons are a term referring to 3d graphics. A Polygon is basically a set of points in the 3d space of the game that forms a simple shape. Then the game draws some texture on top of it.

How is Monstanto not a Monopoly? | As far as I'm aware it isn't being a monopoly that is illegal, its abusing that status to keep out competition. Microsoft's situation had a lot more going for it than just releasing IE with Windows. |
My partner gave up smoking the exact second she was pregnant. She started 9 months later, the day she left hospital having given birth. | If it helps to understand, you never really quit smoking.

The dog doesn't bark at it But does bark at a doorbell on TV.It's an alarming, unusual, and for the dog really really loud and clear sound. So if you immediately think of shouting "I'm coming!" or "The door's open!" the dog does the same but just with barking. That's how I like t... |
How are CPUs produced so cheap when they have billions of nanometer scale components that need to be made? | There are two reasons that combine to get the answer. First, your intuition that complexity is expensive is correct. More parts means more involvement and time which means higher cost. That comes with some caveats and we'll address them now. Yes, it is true that a modern IC can have billions of transistors, the manufac... |
Why do ACH (Electronic bank transfers) take 3+ days | Banking Rules are Pre Internet. some have computers or computer programs from the 1970's that run on batchs run by a physical person. so after hours or weekends the transaction sits in the queue until the batch is run. so all banks run on the assumption that the bank they are drawing the funds from is in the stone age ... |
Why the NBA All-Star Game is getting pulled from Charlotte?? | People protesting a law in the streets don't have a lot of sway.

Why can't we see lasers from things like laser pointers until they've hit a surface? | You can only see a laser when it has a medium to reflect on. Like a cloud of vapor, or gas. The light has to be reflecting off of something in order for you actually see it, considering the photons on a laser are moving in only one linear direction. If it's not hitting anything, there's nothing reaching your eyes. |
Why do we have to wait at least 10 seconds in the middle of restarting the router? | Something to do with it completely powering down so it goes through the full boot up sequence on power up. I can tell you that 10 seconds isn't long enough for all routers. I learned this the slightly embarrassing way by needing to call tech support, wait half an hour on hold, only to have the guy tell me to wait ***30... |
What causes the 'stillness and silence' during snowfall? | Snow muffles sounds - snow covered ground doesn't reflect sound waves as nicely as the regular ground does, and the presence of snowflakes in the air itself disrupts sound waves . The stillness is caused by all the motion around you. There are thousands of falling snowflakes, and your brain has trouble keeping track of... |
Is the Game of War advertising campaign (that I feel like I'm being blasted with) actually working? Are these type of campaigns worth it for the company? | See, I play Clash of Clans casually and their commercials are more entertaining and sort of humorous while the Game of War commercials seem more .desperate to grab the guys lonely enough to play because Kate Upton asks them to be her hero.

The scale of this influence can range from providing arms and ammunitions, ... |
why do radio stations play such limited amounts of songs from a genre? | If you're asking what I think you're asking, it's because radio stations are owned by huge companies like Clear Channel. Clear Channel stations will ONLY play music that the label has paid them to play. This is why independent artists hate radio stations because they can't afford the millions of dollars Clear Channel c... |
Why do some PC games have a 30/60FPS cap? | The only technical reason to have an FPS cap is because you use a real-time game engine. IE: every time a frame is rendered the game advances events in real time. Fighting games typically use this method of rendering which is why you hear pros talking about 'X's block takes 4 frames, but my attack only takes 3 frames.'... |
Does it seem like humanity's development has slowed down or reached a stalemate? | What exactly do you mean? We double in computing power every 2 years, and if you ask me that's pretty impressive.

How does the Superman universe explain that Superman looks exactly like a human, despite having come from a planet millions of years away with a completely different environment? | [From /r/superman]: > In red son its suggested that Earth is an ancient version of Krypton and that humanity's technology will eventually make all humans as powerful as Superman. Personally I think it could also be something along the lines of [convergent evolution], or simply that the comic book writers wanted a hero ... |
this wonky jet stream giving planes the extra speed from a tailwind. What happens if a 777 breaks the sound barrier? | A pilot here. The jet stream itself is beneficial for many reasons: lower fuel consumption, travel time, and thus lower maintenance cost. However, jet streams usually bring on a lot of turbulence. And this type of turbulence is difficult to predict in the cockpit, as it won't show up on the radar. The Mach speed is bas... |
What does western society have against the female nipple? (Serious Responses Only) | I believe it has to do with simply drawing the line somewhere. In western societies, a woman's breast is seen as a sexual organ, and has been forbidden to show in most public settings for hundreds of years. This has relaxed quite a bit over the last few decades, but still exists. We've gotten to the point that you can ... |

Does Schwarzenegger-style body building yield any advantage athletically? Does body building really make you strong? | Body building is about having symmetrical, large appearing muscles.
