Why are the people of Milwaukee so angry over the shooting of someone who was armed? | This hasn't been about individual cases for quite a while. This is about a society which has consistently dismissed or ignored every attempt to call attention to violence and uneven enforcement targeted at a specific community up to this point. It's about doj reports that find entrenched racism in police forces but don... |
Why is rape considered worse than say Murder or torture? | I think it might be considered worse because when you are murdered, you don't have any flashbacks or memories, you are just dead. When you are raped, there is so much trauma you have to go through and your life will never be the same after that.Rape is a form of torture. People place torture as being worse than murder,... |
How do "they" determine the caloric value of a food item? | You burn the food in a controlled environment until it's completely incinerated, all the while carefully measuring how much energy is released. You do this a few times with the same food and average the results, and that gives you the number of calories in the product. Calories are a unit of energy defined as the amoun... |
Why do frivolous lawsuits work in the United States? | Firstly, in these cases, the public don't know the whole story. There are some pieces of the information that only the those involved in the case know. In the Honda situation, just because the driver was impaired, it doesn't mean they should die. For example, if you are driving over the speed limit, it doesn't mean the... |

How are iPhones just as quick as other flagship phones when other phones have quad cores, more GHz, and more ram? | You have kind of answered your own question. If they can make their own hardware and write their own software, then they can optimize their software at a level that can never be reached on android phones. For starters, look at the line of Android and iOS devices. Apple maintains a very small number of devices during ev... |
Why does adding up all of the digits of a number test if it's divisible by 3 or not? | Because 10=9+1. This proof is really a lot easier if you know the [Binomial Theorem], but this is ELI5 so I'll assume you don't know that. To compensate, I'm only going to prove it for numbers less than 10000, but it should be clear how to extend it to any integers. Let's say abcd is a decimal . What does it mean for i... |
Why does it seem like it's easier and more convincing when British, Australians, etc. portray an American accent than when Americans portray British, Australian, etc. ? | I suspect market forces. The US film industry is much larger than the British or Australian, so there's more demand, and job opportunities, for an actor who's good at an American accent than one who's good at British or Australian accents.Classically trained actors in Britain used to be taught to "lose" their accents. ... |
Why does the method of integrating factors work for linear first order differentials? | The integrating factor puts the differential equation into the form similar to the derivative of a function multiplied by another function. [fg]' = fg' + f'g How does it do this? Let's see with an example. y' + 4xy = 2x let's first generalize it to the form y' + by = c to show how it works we know we have to multiply t... |
When a flashlight's battery is dying its light becomes dim. Why wouldn't my phone's screen go dim when its battery is dying? | Your flashlight is an unregulated DC circuit, the battery connects to the switch, and the switch to the bulb, and the bulb to the battery. One feature of unregulated circuits, which you've noticed, is that power droops as the battery is used. This is OK for flashlights, but not computers. Your phone is a regulated DC c... |
Why Are Spiders So Stationary? | The level of activity amongst differing species of spider varies quite a lot. This will be based on hunting style , temperament and environment as well as a bunch of other things such as the last time it fed, the level of risk around etc. I keep tarantulas and some are active a lot of the time. Others are far more sede... |
Why are protesters using green lasers in Tahir Square and in other protests around the world? | I cant say I know much about the protests but from what I've seen its mostly green lasers being pointed at overpassing aircraft. Again, just a guess: It is a common rumor that lasers will blind the pilot of an aircraft and crash it. I don't believe this because most aircraft cockpits only really have windows on the top... |
What's the purpose of Apple keeping $246 billion in cash reserves? Isn't there a lot of things they could spend that money on? | They likely don't have anything at the time that they believe will deliver a high enough return to make it worth investing. They are also likely waiting for some direction on US Tax code for repatriating the money. If rates or lowered or a tax holiday is granted, investors are going to expect significant dividends from... |
Why can't some species of animals be domesticated? | Most of the domesticated animals were domesticated thousands of years ago.

A... |
I have heard the GOP can pull their nominee down before the election and replace him with someone else. Can someone explain this? | The GOP doesn't have a nominee yet, the nominee will be chosen at the party convention in July. Trump is the presumptive nominee because he'll be chosen if all the convention delegates vote the way that they're expected to. However, the party decides the rules of voting at the convention, so it could in principle chang... |
The phenomenon where you know you just fell asleep (after being woken up) | Do you mean the situation where we know we've only been sleeping for a very short time versus for a long stint? Or do you mean that the moment after you've fallen asleep you're somehow aware of that?", 'I think OP is talking about where you fall asleep and realize you feel asleep so you wake up This is easy, at least t... |

How does ibuprofen alleviate a fever? | Ibuprofen interacts with the thalamus , causing it to stop elevating the body temperature above normal. Just a side note: it's healthier to wait out a mild fever by drinking water and taking no fever reducing drugs than to actually stop the fever. A mild fever boosts your body's immune system and inhibits infectious mi... |
Who wrote the bible? | Someone broke a window at school and the teacher got everyone to write down what they saw. You all write it down and give it your teacher. After going through them all they realise that they all compete with each other and tell different stories so they just decide to pick the ones that fit together the best and hope e... |
Do Earth-Like planets have trees and stuff on them? | > am sure these photos are CGI or something Exactly. We've never seen any Earth-like planet up close. We just know that they're roughly the same size and distance from their star as Earth. > but still, earthlike implies water, atmosphere and trees, right? Not necessarily. We have no idea what's on them. Maybe some sort... |
The difference between China's latest intervention to stop further losses on it's stock market and the actions taken by the USA Fed to minimize the effect of the 2008 crash | China has intervened directly in the functioning of the market and set up price floors for shares to try and stop the sell off. The US Fed lowered interest rates and pumped liquidity into the economy following the crash. The first is an attempt to stop the crash from happening by directly intervening in the market . Th... |
Why are horses put down if they break a leg during a race instead of rehabilitating the injured animal? | Explain like you're 5? **The horse doesn't get put down, sweety, it just gets taken to a special horse land where it can recover**", 'One, rehabilitation for our horses is VERY expensive. Two, horses are actually very fragile and susceptible to many diseases and disorders. By being off their leg for so long, the horse ... |

Is 3D Touch/ForceTouch not just "click/tap and hold"? | It is just pressure sensitive touch. If you touch and hold, a menu pops up, while holding, press harder, and another action happens. This isn't new in the tablet/wacom world, but Apple is a fantastic marketing company. |
How sleeping gives you energy, or helps you "recharge." What does sleep do? | Although this isn't a complete answer, it may broaden your understanding of sleep. Adenosine builds up in your blood every hour that you are awake. I remember reading that your body is always breaking down adenosine, but when you are sleeping your body produces it at a slower rate which causes you to decrease the amoun... |
Can ants or similar size insects see things that we can't? | It depends on the kinds of eyes they have. Most arthropods have compound eyes that consist of many ommatidia which are individual photoreceptor units. Many of them even see different color spectrums. Honey bees cannot see red, but they can see UV . Typically when people come up with schematics of what insects see it lo... |
Why can't I wake someone up when sleepwalking? or can I? is that true or a myth. | You can wake them up, nothing horrible will happen. However, they may be very startled. Source: I've been woken up while sleepwalking. I was just very confused as to why I was in the garage in my underwear. |
How does weed killer 'know' to kill weeds and leave everything else alone? | The weed killer doesn't know, you have to pick the right one to use! A selective herbicide is poisonous to certain plants. You pick one that doesn't harm plants you wish to keep but kills things you don't want .After working for chem-lawn for a couple summers, here is what I learned: The weed killer is usually applied ... |
Why does the American government not use the anti-trust laws as often as they did in the 19th centuries? | The Sherman Antitrust Act was only enacted in 1890. There were only a handful of major cases filed before the end of the century. These days, regulators generally prevent combinations/mergers before they happen rather than breaking up integrated businesses on the back end. But antitrust actions are still very much A Th... |
Why do some people always feel tired after waking up (no matter how many hours they have slept), and others always wake up with a burst of energy? | So have you talked to your doctor? That sounds like some of the symptoms of my wife's sleep disorder called hypersomnia. All this medical advise coming your way and the real answer is talk to your doctor. They went to school to learn what is abnormal for literally a decade or more. Let them provide that information. |
How do street signal lights know when to change colors? | Magnetic sensors in the street. That's why lifted trucks and motorcycles have a hard time tripping the sensor. You can see the cuts in the street on some. |
Why were chickens, cows, pigs, and sheep chosen as the four main animals of domestication and cultivation by our ancestors? | Actually, dogs were first, and goats were before cows and chicken, and cats before chickens. But anyway, the reason they're common is because of how long ago we domesticated them. So we've been able to shape their characteristics overa long time to make them into what we want from them. Sheep used to not have quite so ... |
Why is it sometimes really hard to peel an egg without removing chunks of egg white? | The theory is that the way you cook the egg will determine how much egg gets peeled with the shell. Some people say to add salt when you cook the egg, some people say baking soda. Some people say put it in a cold bath immediately after, some say let it rest. There are all sorts of theories. If you google it, you'll get... |
Why do schools allow children to skip one to so many grades? | No. I skipped 4th grade. It's mainly due to those kids who are just smart enough for it, and would be wasting time in lower grades. I didn't miss out on any social interaction, though I was pretty inept . |
Why can't we explore the oceans' floors? What technological advance must be made to make it possible? | You're very much underestimating the amount of force at extreme depth. The average sea depth is 3790m, and at that depth you're dealing with an external pressure of 376.982 atmospheres, or 5,540.11 psi. The Virginia-class submarine, the new fast-attack subs for the US fleet, is rated for maybe 400-500 meters at best. B... |
How is KFC getting away with not revealing their secret herbs and spices? What if someone is deadly allergic to something they don't want to reveal? | TIL a method of determining the KFC recipe by shotgunning letters asking if X is an ingredient as 'I have a deathly allergy'. Edit: TIL a horrific human experiment, replacing letters with people with the specific allergies in the above method. |
Why are people threatened by gay marriage? | Many people hold a sincere belief that engaging in homosexual sex is morally wrong. What they fail to even consider is that they feel exactly the same way about sex outside of marriage, yet they don't make such a big fuss about it because they're just used to it. |
Why are there many conditions that prevent one from being able to see or hear but none really that affects someones sense of smell? | I know someone who was born with no sense of smell. I guess she could be lying, but she's the only person who doesn't leave the room after I fart |
Why does the sun hurt your eyes if you look directly at it, but not if you see it in your peripheral vision? | If you look at it in your peripheral vision, only a small portion of the light is entering your eye and hitting the surface of your retina.

Why do children cry when they experience physical pain but adults rarely do. | Children can't take care of themselves, and crying gets their parents' attention. Adults, on the other hand, can take care of themselves. Crying about small booboos serves adults no purpose. But remember that everyone is different. Some people react to pain by crying for their entire lives. |
How do websites that don't have ads on them and don't sell anything create revenue? | Many websites don't generate any revenue at all. They're funded by investors who support their growth in hopes that once they're popular, they can be monetized. |
Why do 4Channers despise Reddit, and vice versa? | Troll nation. Redditors try to be intelligent and witty, 4chan thinks they're witty and smart. Both fail 9/10.There's a lot of overlapping in what I imagine are largely similar communities. A good portion of people who are tuned into the Internet all the time—moreso on 4Chan hence the self-deprecating title of "autist,... |
Why do little kids add an "e" after some words? | Parent of toddler here. She will say whatever she picks up from us. We call most dogs puppies and cats kitties. My child is three and told another adult tonight that a flower smelled delicious. She's also used the word hypocritical in correct context. And she curses like a sailor. Little kids learn language from whoeve... |
How does ultrasound machine that sterilizes medical equipment work. | An ultrasonic cleaner doesn't actually sterilize the instruments. It helps to loosen particles that are stuck to them. The instruments would need to be run in a separate machine to sterilize them such as a statim or midmark after going through the ultrasonic cleaner. |
Can We Melt Diamonds? | I read a crime thriller a while back where a major plot point was based on the 'fact' that you could just touch a gas torch to a diamond and it would instantly transform into a worthless lump of coal. Is that really true? In any case, isn't carbon amazing in the range of forms and properties it can take. I don't think ... |
If multivitamins "don't work", then why do foods fortified with vitamins/other like milk and vitamin D or salt and iodine actually work to decrease deficiencies? | It really depends on a lot of things - diet, nutrition, weight, age, etc. Overall /u/xrobyn is right that they can and mostly do work if you're deficient - although they shouldn't be your only source if you are, only a supplemental aid. You should rework your diet in order to get more of the vitamins through there beca... |
Why can't or aren't humans being cloned? | They can be. They wouldn't be the same person due to differences in memories and upbringing, but they would look the same and have similar mannerisms. We don't because of ethical reasons. |
Why do american realtor sites seem so unprofessional? | In my personal experience, it's due to: Most realtors are not particularly intelligent, well-educated, or skilled. They usually have some other job that actually pays the bills, so they don't devote full time and effort to their part-time realtor gig. It doesn't behoove them to spend lots of time per listing in terms o... |
why do new airplanes or newly update airlines still have cigarette ashtrays in on the planes when smoking has been outlawed for a long time now | I have heard that's it is because there are some people who will smoke anyway and having them extinguish their cigarettes in locations that are not adequately prepared can cause a fire -- literally everything onboard is flammable. It's better to have them theAn not to have them. |
Why do actors get so much money? | These salaries follow the laws of the market. Supply and demand, where in this case the supply is just one. Some people are unique for what they do, some are unique for what they are. When this uniqueness is in high demand , the salaries go up. The producer who pays The Situation and the rest of the case millions a yea... |
Why does checking your credit score decrease your rating? | It doesn't. Applying for credit will decrease your rating. But a soft credit inquiry, such as when you are checking your own credit history or credit score, doesn't affect your credit score at all. |
How does a kidney work? | > Is it just like a filter, keeping bad stuff and letting good stuff pass? Kind of. It's more like a filter that takes a lot of good and bad stuff out of the blood and then, later on down the line, reabsorbs the good stuff back into the blood. This is done by using proteins that bridge between the kidney's tubules and ... |
; If you pour high concentration alcohol (ethanol, methanol) on a fresh wound to clean it, do you risk alcohol poisoning? | No. It evaporates very quickly. If you look at most hard alcohol that we consume, it's 80 proof. This means that it's 40% alcohol by volume. In order to get alcohol poisoning, you need to consume a large quantity in a short period of time. Just to make the math easy Let's say you've got a small body weight and no alcoh... |
What are intrusive thoughts and should I be worried about them? | I have intrusive thoughts quite a bit and I've noticed that what helps is to just let yourself think about them. The harder you try to avoid them the more likely they'll stay in your head. Realize that they are normal and let them come and then pass. Thinking and doing are very different things.Intrusive thoughts are u... |
How is something like a gunshot to the head or a high-force impact able to kill someone instantly? | Instantly is a relative term. A blow to the head disrupts brain function. That disruption knocks a person unconscious. If the brain is too damaged to function then that disruption is permanent. If that damage includes the part of the brain that controls the heart then it stops too. If it doesn't then the heart keeps pu... |
What causes the "second wind" after staying up for a very long duration, (over 24 hours)? | your body will release chemicals to aid you in what you should be doing. Late at night, your body is trying to get you to sleep. If you stay up, you essentially override that urge, and your body realises that you don't want to sleep, and then cooperates by releasing chemicals to keep you awake. Same reason that you get... |
What is Kratom, and why is the DEA so interested in banning it? | It's a plant from South Asia that is used, mostly, as an opioid substitute. As of 2013 no clinical trials had been done to understand kratom's health effects and it had no approved medical uses. In areas where the plant grows, it has been used in traditional medicine since at least the nineteenth century. Some people t... |
What is a Polestar, how can I spot it in the night sky and how is it significant/used? | The earth is spinning around the line that passes through the north and south pole. If you continue that line out into space it passes near Polaris in the northern sky, and the octans constellation in the southern sky. So, as the earth spins, the stars appear to circle around the north and south pole, with the stars di... |
how do organisms without brains (starfish, trees, jellyfish, etc) know how to "do" things like mate, flip over, swim, etc? | In essence they don't *know* anything. Arguably the same is true for organisms with a brain. It's open to debate precisely what *knowing* is. After all, how does wood know to burn when you set it alight? How does a stone know to fall when you drop it? How does your heart know to beat? At a basic level, what we call con... |
Why isn't UTI medication available over the counter? | I think another issue would be people self-diagnosing UTI's when you could have something else going on We don't want people to become their own doctors. |
Why does my computer care when I "unexpectedly" eject my usb flash drive? | Sometimes, computers will just store data in a cache before it actually writes it to the USB drive. This speeds up file transfer times during the file transfer, but if you remove the drive before actually ejecting it, that data doesn't get written. You have to click eject, and then it finishes writing the data to the a... |
Why does down syndrome make people (animals) look the way they do? | Basically all cases of Down's have the same cause which causes the same growth problems that give downs sufferers their appearance. Having a different Chromosome duplicated would causes different problems, but almost all other Chromosomes' functions are so important that most foetuses would die within a few months, so ... |
Mortgage repayment - why can't you take out a longer mortgage then just repay it quicker to save money? | A 40-year mortgage can make your monthly house payment more affordable. But mortgage brokers say such long-term loans generally aren't the best choice for most borrowers because they typically come with a higher interest rate and cost more in interest over the lifetime of the loan [source] |
Why does my dog spin around 3 times before she lays down? | Because you're lucky. My dog spends three *minutes* turning around one way, pawing his bed, turning in the other direction, roughing up the bed again, sometimes uses both front paws at the same time like he's leaping onto a mouse or something, etc. Big problem is, [he's a Great Dane]. He's pretty much destroyed some of... |
When we are sick, don't we often just try to fight our bodies defense mechanisms rather than the illness? | Those symptoms arose from your body doing things to help fight the infection, and for a lot of them the symptom is also used by the bacteria/virus to help spread itself. Your bodies expectoration of mucus and partially digested foods is generally done to help try and wash away the bacteria. And a fever is your body shi... |
What would happen if i plug my ( USB ) headphones into my phones usb adapter that goes in the wallsocket and put the headphones on. | Nothing significant. Your headphones' circuitry would power up. Depending on the adapter, the headphones might then try to talk to the adapter, but the conversation would be pretty short because they don't have anything really to talk about.They would be powered, but no sound. Different wires are used for power and dat... |
How do people develop "types" when gauging another person's attractiveness/personality? | The golden ratio comes into play when we think of typical beauty. So famous people, photoshopped people, people with great symmetry. There's also a genetic variable that comes into play, I watched a documentary when I was younger so I don't remember the title. But in this documentary it mentioned how women and men stil... |
Why do people hate Nickelback so much? | It's generic. Bland. Cheesy. Overdone. But mostly, it's a trend to hate them. Their music isn't terrible. It's mediocre. |
Why, if found guilty during the verdict of a trial, would someone be awarded a harsher sentencing for claiming innocence as opposed to having a lighter sentence for pleading guilty? | It's not only saving the state time and money at trial. Defendants who plead guilty also give up their right to appeal. This saves the state decades worth of work and millions of dollars. |
Why do so many teachers demonize Wikipedia? | Wikipedia is an amazing source of information. It's the online encyclopedia that we need. 99% of the time, I'm looking up simple facts such as the year a celebrity was born or a band's discography. There's likely no debate to those facts and no reason I should look elsewhere for the information. However, you shouldn't ... |
Do heart transplant patients need to be of the same blood type as the donor? | As others pointed out the heart does not make the blood, that's the bone marrow. But the blood type for a heart transplant needs to match just as it would for a blood transfusion or there will be acute rejection. HLA compatibility is a factor, but blood type takes priority, and all heart transplants are cadaveric so th... |
Why and how does smoking cigarettes kill you? | Like all chemicals that cause cancer, whether it gives *a particular person* cancer involves a lot of luck. Random chemical damage to DNA in a cell usually just damages or kills the cell. It's bad luck if the damage happens to turn one cell into a fast-multiplying, life-threatening cancer cell. |
Why does the sun look orange during sunrise and sunset, but yellow the rest of the day? | It's due to the same process that makes the sky blue. Longer wavelengths of light like red and orange tend to pass through the air unchanged. Shorter wavelengths like blue tend to get scattered in different directions by the oxygen and nitrogen molecules in the air. Like throwing a ball through a stand of trees, someti... |
If an ambulance is responding to a call and on their way they see a hit and run/car accident what is the EMT's priority? | I don't know about ambulances but years ago my house caught on fire. A kid at a nearby school had pulled a fire alarm, the fire truck had to drive past my burning house to go to the school. House ended up being a complete loss. There was a big uproar about it since there had been 3 false alarms at the school that week ... |
If you get disemboweled, and someone touches your organs outside of your body, do you feel it inside of you or wherever your organ is? | Here's an experiment. Cross your fingers. Then close your eyes and touch the ends. One at a time, as well as simultaneously.Not a medical professional, but the words "unconscious" and "in shock" and "dead\' come to mind. Read about a girl that sounds like might be this one -- guts being sucked out her anus; cannot eat ... |
why do humans hate being lied to? | People tend to dislike being manipulated and most lies cover up something or hide something, which puts the person that is being lied to in a position of ignorance in regards to a particular topic which ultimately takes from that persons capacity to understand their circumstances and work with all available factors. I ... |
Why a trip to Mars is more feasible than Venus, and what a trip to Venus would entail. | Venus is a planet, that at its surface, can cook a pizza in a few seconds. There is also a lot of pressure and no water. We need stuff that can withstand devilish temperatures, high pressure and pack with us enough water. Mars is mostly a desert. There are low temperatures, but during summers, they can get up to -5^o C... |
If blood travels through veins, why is there blood everywhere? | Because veins go everywhere. Actually, technically, because arteries go everywhere, and veins go from everywhere to the heart. Blood takes oxygen from the lungs, which take it from the air, is pumped by the heart to go everywhere it is needed which is every part of your body that isn't dead. If there is no oxygen, ther... |
Why are gorillas so strong when all they eat are fruits and vegetables? | There's really no correlation between being 'jacked' and being an herbivore. Gorillas do actually eat animal protein – grubs, ants, etc. – but think of all the strong animals that are vegetarian: black bears, elephants, horses, rhinos, buffalo, etc.Generally speaking strength comes from tendons, not muscles. Even if i ... |
How do air breathing sea animals like dolphins or whales not drown during violent seastorms? | the more violent the storm, the larger the waves. the larger the waves, the longer the time between waves. an air breathing mammal would have plenty of time to grab a breath in a large wave trough. Not to mention - whales and dolphins can leap from the water. Not sure if they are able to grab a breath while doing so or... |
How do plants (trees specifically) know when to start growing again in the spring? | It's a mixture of temperature and day length. If it was as simple as air temperature, you'd get trees leafing out in December on 50 degree days! Soil temperature changes slower and is less susceptible to wild swings in air temperature.Longer days, warmer weather loosens up the stored sap for easier transfer to grow new... |
- Why are the rings of Saturn, which are presumably just floating Rocks, perfectly lined up in a huge ring instead of crashing into the planet due to gravity? | The rings are basically dust and pebbles orbiting the planet. Now if those were all on different inclinations, like a sphere, they'd constantly crash into each other. Similarly if they were all going different speeds they'd crash into each other. So what happens is that the system basically averages itself from the dis... |
Why do so many sick people smoke marijuana, instead of consuming it by other methods? | Eating weed does nothing for me. That combined with the typically small dose in edibles makes it much more cost effective to smoke weed or wax or keef. |
How does the glass from a car shatter into small, almost uniform bits, while most other glass shatters into random shards. | Car glass is all a specifically manufactured *Safety Glass* designed to crumble instead of creating shards. _URL_0_ It's done that way to prevent people in car accidents from being injured by long shards of broken glass.There are two varieties of glass, created by different cooling methods. Annealed glass is cooled qui... |
What would be required if I were to attempt to start up an internet providing company in say a small town? | Permits and fiber optic cables or co-axel cables. You'll want to have a truck with a bucket lift to install cables across power lines or be ready to dig to lay it a couple feet underground. |
What the world would be like if mosquitos disappeared tomorrow? | I've lived in Hawaii for years now. When I first got here, mosquitoes *fucking* **loved me**. Hands down I was their delicacy I swear. After about a year, they just up and stopped for some reason. Now I notice, even if I'm in a cloud of mosquitoes, I'll get only one or two bites but if someone who's new here is with me... |
How do mirror screen protectors work? | Nothing clever - they're just slightly silvered. When the screen is off there's no light from behind and the silvering appears total so it looks like a mirror. In fact, they *would* be letting light through from behind if there were any - what little gets through isn't much reflected from the dark screen. When the disp... |
What's the difference between normal rice and "minute" rice? | Dry rice does not let water penetrate to the inside very well. So while cooking, you're waiting for the water to slowly make its way to the inside, so the grains become soft enough to eat them. Instant rice cooked in a way that cracks the surface, and then dehydrated. When cooking it again, the grains suck up water lik... |
How a fire alarm still beeps after the battery dies | The battery in fire alarms is generally only a backup. There should be a connection to the building's electricity on the fire alarm itself. The beeps produced by a fire alarm without a battery can be powered by that connection. |
When animals are fighting, why do they sometimes pause in the middle of the fight and stare into empty space? | They're trying not to get hurt. Animals fight for their lives and any injury could essentially be a death sentence. More than likely they're considering escaping the situation but don't want to make themselves vulnerable. That or they're dazed/tired and need a second to get their bearings. Edit: that flip kick to the h... |
How come astronauts would burn up in atmosphere upon re-entry from space without a landing craft but Felix Baumgartner was able to jump from the edge of space without getting singed? | First off, Felix Baumgartner jumped from 39km, space is considered to begin at 100km. The reason that he wasn't singed was that he wasn't in orbit of the Earth. To be in orbit he have to be going sideways **very** fast. Coming in from orbit, he would have to dissipate his potential and kinetic energy. Since he just jum... |
I'm all for free speech, but how is /r/CoonTown/ and it's over-the-top-racist "Chimpire", a thing on Reddit? | Censorship is censorship, the reddit admins aren't very keen on banning subreddits left and right, no matter how inappropriate. Bad press is an entirely another matter, /r/fappening was not illegal per se but due to the public outcry the admins banned it.Some people just want to watch the world burn Just like that, cov... |
Why is pizza usually the only food that is delivered? | What Everyone else said plus pizza stays fresh longer like imagine ordering something like fish tacos or a baked potato for delivery, 30 minutes later it's probably not going to taste great and will be soggy and gross. Pizza stays good and hot and fresh", 'pizza is the most efficient party food. you could buy a meal fo... |
Why are men's clothes sold with clear measurements in inches or centimetres, but women's clothes have arbitrary numbers for sizes that can be totally different between shops and labels? | I'm not too sure about this answer, but my guess would be a couple of things: 1. Letting ladies stay in the store longer by trying on a bunch of the same sizes increases the chance of them finding something new to buy instead. 2. The clothing company can try to capitalize on the laziness of people. There are probably o... |
Is the Deep Web illegal? | No, the deep web simply refers to sites that are not indexed by the usual search engines, such as Google. Everyday things such as your email inbox or parts of Facebook may be considered deep web, as those contents don't show up in a Google search. But I assume you are referring to the darker parts of deep web, such as ... |
Why are the French able to inaugurate their elected president a week after the election, but the United States doesn't inaugurate their president until months later? | Originally, the President didn't take office until March, so the problem used to be worse. The Constitution was modified by the 20th Amendment to move the date. Because the dates of the Election and the Inauguration are specified in the Constitution, they can only be changed by Amending it, which is incredibly difficul... |
Why haven't there been any manned missions to Mars yet? | For a matter of fact there's an actual [plan] to put a human colonization on Mars. But as others have pointed out getting back off the red planet is near impossible so I'm afraid it's a one way trip. In terms of cost, it would be much more expensive than sending the usual probe to Mars since that food and enough recrea... |
How do you know if the ice on a frozen lake is thick enough - and safe enough - to walk on? | When I was a kid, a parent always drilled down to see how many inches thick the ice was. If it was 6+ or so, they'd allow us to play hockey or ice skate. |
