6jfy0v | Technology | Why can't my phone simultaneously use wifi and data? And, given that that my phone is limited to the one or the other, why is my connection interrupted whenever I switch between wifi and data? Is is possible (i.e. does the technology exist) to switch seamlessly between the two? | Although in both cases you might be trying to send data to or receive data from the same server, you're using physically separate hardware to do it--one, a system designed for communicating with routers over Wi-Fi, and the other, a system for telephone communication. These also operate on different frequencies. The ope... | 2 |
l7i4h3 | Technology | How were video games in the late 80s/early 90s animated before huge digital advances were made? Additionally, how was music added? | In case you're interested, there are some incredible resources for making 8 bit games on retro systems available for free. Arcade Game Designer (AGD) for the ZX Spectrum is particularly fun. Highly recommended! | 5 |
6imtsw | Biology | Venomous means harm is done with injection. Poisonous means harm is done when ingested... But is venom poisonous, and is poison venomous? Like, will eating a venomous critter poison you? My boyfriend joked about eating a venomous critter we found and (oopsie daisy) killed... Even though he won't really do that, I quest... | Most venoms are not poisonous. Most poisons are venomous. (That sentence is wrong, but we're having a conversation.) Venoms are *usually* proteins that are produced to do a very specific thing, they are designed to be injected into soft tissue and act very quickly. Most venoms are neurotoxins, meaning they target nerve... | 3 |
amsca9 | Technology | If music CDs are burned with the opening tracks towards the center, how are open-world video game discs burned? Like Fallout 4, for example. You can walk anywhere, do anything, talk to anyone, at any time. How is that all rendered onto the disc when it’s not exactly chronological? **EDIT**: thank you everybody! I appre... | Other posters mention optimizing disc layout but I can speak firsthand to some of the lengths we went to in days of yore to minimize load times on optical media. In PS2 days I spent the better part of a month writing a layout optimization tool whose goals were the following, in order of importance: 1. Position level da... | 18 |
62x3wv | Engineering | How did the western world lay underwater telegraph lines as early as 19th century with their level of technology? | They'd already mastered telegraph lines on land, so what they needed for underwater cables was a way to waterproof them. Unlike today, when we have all kinds of artificial substances, they could only use natural ingredients. So one of the vitally important substances that allowed them to do this was gutta percha, which... | 5 |
6vwbwi | Chemistry | Why are some liquids, like oil, very slick? What molecular properties make a good lubricant? | Substances like oils have many carbon atoms that are saturated, or completely covered by hydrogen atoms. If many of these molecules are near each other, they will not (generally) form hydrogen bonds because the carbon atoms do not attract hydrogen as much as oxygen atoms for example. On the stickier side of things, sug... | 1 |
gxxgka | Economics | how come mobile games can pay for ads in other mobile games | A broader questions is:how much money to spend in advertising? The easy answer is: if putting advertising to get new users is less expensive than the money that users will spend, then it's good to advertise. But it can get complicated. For example, many people prefer games that already have many players. This is usuall... | 2 |
jzbujs | Engineering | When we suck through a straw, the substance follows the suction to the source: our mouth. So how is it that when vacuum cleaners suck up crumbs, the particles fall into a dust bin instead of clinging to the fan or filter in front of it that causes the suction? | It's mostly to do with the large density difference between air and dirt. The vacuum cleaner is also sucking up air and the air easily flows past the solid particles. With a vacuum cleaner the speed of the air is fast enough to lift particles up in the hose, but when it enters a larger chamber the air speed slows down ... | 1 |
6j9hsw | Culture | Why does "The People's Republic of China" have the word republic in it when clearly the country is not one? | I think you are mistaken about the meaning of the term republic. In its most base form it just means that a state is a "public thing" and is used to contrast with monarchies. Outside of the US where it has a slightly different meaning somebody calling themselves a Republican means that they are for the abolishment of a... | 5 |
b1dk73 | Mathematics | How is Pi programmed into calculators? | As most people have said, its either hard coded or estimated using a fraction thats pretty close. HOWEVER, most calculators will also track whats going on with the knowledge that pi is being estimated, so if you do something like 'pi/2' and then take the answer and double it, you get exactly pi rather than some weird a... | 16 |
afk38m | Chemistry | What's the difference between shampoos for straight, curly, wavy, etc? Is there really a difference or is it BS? | Followup question; If I have curlyish hair, and i want it to be straighter. Do i get the shampoo that's called "For straight hair", or "For curly hair". The grammar is super ambiguous for me. Ive read the bottles and tried both (and other variations) and I can't work out what would suit me better. | 10 |

9bn41v | Biology | Why does Down's syndrome give very defining physical characteristics while other genetic disorders don't? | Down syndrome is caused by having an extra 21st chromosome (or a partial 21st chromosome). Many genetic conditions are caused by a mutation in a single protein or protein complex meaning if it were to affect physical appearance then it will usually be minor, but containing an extra chromosome means potentially hundreds... | 2 |
5pokog | Technology | How did MS-DOS make Microsoft an OS power house? | I'll have to leave most of your questions to others, but here's the answer to your first one: Microsoft's deal with IBM (to create/supply the operating system for the brand new IBM PC) allowed Microsoft to license the operating system to other computer manufacturers. When the makers of IBM compatible computers started ... | 3 |
kdziee | Economics | What exactly a "right to work" state is in the U.S and how does it affect workers. | Unions and companies negotiate a contract.The union represents the workers, not only in contact negotiations, but also grievances for violations of the contract.

According to [this article]( URL_0 ), **second-degree murder** is causing the death of a human being, without intent to cause that death, while committing or attempting to commit another felony. The other felony was assault and so Chauvin was found guilty of this definition of th... | 3 |

ge1ppa | Technology | How do computers understand programming languages? So I just got into learning JavaScript, and I wanted to know how complex commands are translated into the binary that computers use. Also, how do computers know that a certain string of ons and offs from their transistors mean a certain command, even abstract ones like... | ELI5 that concept is challenging. But essentially the Javascript you're writing gets interpreted into another few languages before actually becoming binary code. Binary code is a representation of what is actually occurring in the physical level of your computer. Conversely, the physical component of your computer repr... | 4 |
9bzevj | Engineering | How do boat sails work if the wind is going the wrong way? If the wind is going towards you, how are you going forward? It doesn’t seem like a very reliable system, same if there is no wind. | Oh I did this one a while back and found some neat diagrams. Wait a mo: Edit. Damn can't find it and Oh well here's an improv version with not as good diagrams. You can't sail in to the wind but you can sail at 45 degrees to the wind, and use this to zigzag upwind. In fact sailing against or sideways to the wind is fas... | 4 |
mh9tco | Biology | Why do our bodies/ every living things body need water to survive? I understand that we need for to survive since we break down the nutrients inside for energy, but the use of water confuses me | Virtually all the chemical reactions in our bodies happen "in solution"...the chemicals are dissolved, or at least free floating, in a fluid. For humans (and all other forms of life we know about), that fluid is water. Water is what lets the molecules that "make us go" move around and interact with each other. Without ... | 2 |
9ta3ob | Technology | Why do 4k videos look cleaner on a 1080p panel than 1080p videos? | Video typically uses lossy compression which means, you throw away data about pixels. 100% lossless compression is possible, but it would result in massive video files. For lossy compression, you set up some target of how many bits you want to use, on average, per one second of video. To achieve good compression, this ... | 3 |
i9da33 | Engineering | Why aren’t car tires just made out of solid rubber instead of filling them with air? | 1. Because rubber is expensive and it would cost more. 2. Because solid rubber is waaayyyyyy more rigid than air. Sure something like a rubber bouncy ball might bounce, but trying just squeezing it in your hand and see how much it gives. You’ll find that although it squished a little bit it’s actually pretty hard. You ... | 3 |
6egy0f | Biology | How is high salt intake "bad for you" if the Japanese eat so much of it and have the life expectancy they do? | It isn't, unless you have an existing heart condition. High-salt meals cause a short-term rise in blood pressure. For much of the late 20th century it was believed that long-term salt intake caused chronic high blood pressure. Chronic high blood pressure is known to cause health problems. But research in the last few y... | 2 |
7u54ck | Engineering | I’m lying on the couch and staring at the ceiling right now. Why is the ceiling bumpy as if there were tiny rocks embedded in the paint? How do they get the paint to be so bumpy like that? Is there a benefit from having it like this. | Oh god, textured ceilings. I remember those when I was a kid. They must have been all the rage in the 80s because every house in my development had them. I would always accidentally scrape my knuckles on that shit where the ceiling was lower due to the stairs above it. | 4 |

nxnh5u | Physics | How is the newer cars are more fragile during an accident but are more safe for the passengers | They design them to be. Cars nowadays are designed to destroy themselves to take the brunt of the damage. The thinking (and rightly so) is a human is worth a lot more than a car. Seems kindof simple, but in the 50s and 60s, even though every car designer would have agreed with that sentiment, the knowledge on how to do... | 5 |
ai53ql | Biology | Why has the average height of humans drastically increased over the past 100 years? How tall will humans be in 100 years? What about the year 3000? Is there a height that our bodies will definitely cap out at? | If you live in a first world country with a good social net or at least are born to rich and caring parents, once you reach adulthood you are about as tall as you ever could possibly get. There are two things that influence how tall you might get: genetics and environmental factors. Genetics are what you inherit from y... | 14 |
a57xfy | Other | Why can’t hockey teams just use a morbidly obese person— someone whose body blocks most of the net— as goalie? | The goals are far too big for any one person to block them. Much better to have a goalie who's agile enough to move around and block the puck whatever it's coming from. | 6 |
gxxbgu | Technology | How does restricting password length or repeating characters make a password more secure? If it doesn't, why do some companies enforce it? | They want to prevent people from using "a" as their password, so they implement a minimum length. They want to prevent people from using "aaaaaaaaaaaaaaa" as their password, so they implement a restriction on repeating characters. For maximum password lengths, no idea. Either they are stupidly storing passwords in plai... | 5 |
a0pn07 | Chemistry | With all the forest fires recently in the world, how are forest fires traced back to the original starting point? Thanks in advance. | Mostly satellite replay. It’s very interesting what they do, my father is a fire inspector and in 2016 they shipped him out to Fort McMurry (A forest fire wiped their town). It’s different for houses, that’s what he mainly gets jobs at in our small town. | 4 |
5pdva0 | Economics | How come the US spends a higher percentage (25%) of its budget on healthcare than the UK (18%) even though it doesn't provide free healthcare like the UK does? Where is all the money going in the US? I was under the impression that healthcare in the US was mainly private, so how come the UK provides much more comprehen... | It's worth noting that you made a small mistake. The U.S. government does not spend 25% of it's budget on healthcare. The wiki link says it's 25% of *mandatory spending*. That is only part of our budget. > Major categories of FY 2014 mandatory spending included: > ... **Healthcare such as Medicare and Medicaid ($831B o... | 8 |

The entire necessity of flossing is being heavily questioned, and some argue it's more detrimental than beneficial. Sure, flossing on a case by case basis is good, wi... | 2 |
6g0a40 | Biology | What advantages did modern humans have over other animals, other than intelligence? People often seem to think that our brains was what put on us on the top of the food chain, but I find that was not enough in the earliest start of our species. I do hear once in a while that humans have a crazy stamina compared to most... | When I took undergrad evolution we discussed a few things human do especially well: 1. Heat regulation. With adequate water, we're especially good at surviving in the heat. Lions, for example, can only exert themselves for a short time in the heat (think 90 F+), whereas humans can run for hours. This isn't a minor diff... | 8 |
8huf2s | Other | Why Germany had enough resources and manpower to start WW2,despite losing in WW1 just 20 years before? | Well, starting a war requires significantly less resources than actually winning a war. Also it should be noted that the Germany Army is often wrongly portrayed in popular fiction as this high tech behemoth, which it not really ever was. E.g., at the start of WW2, basically all German Artillery was still horse drawn, s... | 17 |
fzltru | Other | How are public opinion polls kept unbiased despite people who are unwilling to participate? Edit: nonresponse bias | In theory, you weight different demographics to adjust for reporting rates based on historical norms. In practice, this is difficult to pull off because those historical norms are themselves subject to bias. Ultimately, you need some sort of ground truth to compare against. So let's say you're polling on whether the ne... | 2 |

7n8l3h | Physics | Why are there areas of turbulence in a flight and other areas without, even if it is at an altitude above the clouds? | Turbulence is essentially rapid changes in the motion of air around a plane. Close to the ground it can be caused by the air being slowed down by friction, or being diverted around buildings or mountains. Under clouds it's usually because of hot air rising and cold air sinking next to each other, so a plane goes quickl... | 2 |
6cnmqw | Biology | Are birds reptiles? | I'll take a swipe at this. Within the vertebrate phylogeny (check out this one: URL_0 ), birds (class: Aves) are sister to the crocodilians (class: Crocodilia).

Considering the decision today that J & J has to pay a massive fine to claimants regarding their baby powder reportedly causing ovarian cancer, I'm unsure about the science behind the claim. What's in talc powder that could be risky? Are ... | I am not extensively familiar with this particular court case, but be weary of results from lawsuits. Civil cases are decided by the jury or the judge based on the arguments they hear in the courtroom, which can result in ridiculous conclusions.

kxlhjr | Technology | Why do some LEDs still glow after turning them off? I got some multicolor LED strips in my room and when I use the remote to shut them off for the night, a few of them still glow. Why does this happen? | The ELI5 explanation is: bad design. There is enough leaked current from whatever the are using to control the current (triac/transistor/SCR) that feeds the LEDs. There are ways to fix it | 1 |
iru7r5 | Other | Why are basements not a thing in Asian countries? | Very few basements in California. When I moved to the East coast and our place had a basement, I was excited. It would be like kids in books... Then I got there and saw the basement. Big letdown. | 8 |
f5scqp | Engineering | Why can we not build a machine to go to the very bottom of the ocean but we can land on the moon? | It's easier to keep 1 atmosphere pressure in than it is to keep many atmospheric pressures out. This is basically it. At the bottom of the ocean you can get up to hundreds of times the normal atmospheric pressure (google says up to 300 times the pressure at sea level) , pressing in on a craft. In space you got 1 atmosp... | 7 |
keimvh | Biology | why do humans kiss, hug, hold hands or love to come in touch with other humans? | First, this isn't just humans but most mammals (and frankly a lot of other animals) that enjoy physical contact. I'm not aware of the neural chemistry behind it, but essentially it takes a lot of trust to make physical contact with another living thing. Sustained contact means you're probably with a trusted ally and th... | 1 |

kmt1lq | Other | Why do we make road markings white, even in areas that get heavy snow? This has always bothered me. Why do they continue to make most road markings white, when they are almost impossible to see in any kind of snow? | Mainly because white marks are the easiest to see against the black of the asphalt, even under a layer of snow. White is also a supercheap pigment, so it's economical to use on roads. | 2 |
jb28ch | Biology | What process in our brain makes something "cute" and something else "ugly"? | Someone else already mentioned the baby aka "super deformed" preference our brains have. Another preference our brains have is for symmetry. We naturally find symmetry beautiful especially in faces. If someone's face lacked symmetry due to scarring or a deformity, our brain tells us that's ugly. This is why typically v... | 2 |
icvcfi | Physics | - Why do flies not die when you smack them? I’ve been thinking about this a lot recently. Why do flies not die instantly when you smack them out of mid air? I’ve been thinking about the relative size and speed of a hand, and I just don’t understand how they don’t die! | There are 2 few reasons. First of all, the power of your hand is divided by its surface, when you slap a fly, it only takes the amount of force you have in the section of your hand in contact with them (so less than a squared centimeter). Their body is basically an armour, so the shock is also shared on their whole exo... | 1 |
6pw4sg | Technology | Can anyone explain awful dubbing on TV ads? I've noticed that here in the UK some adverts have English actors doing the voice work, but the dubbing is terrible! | It's cheaper to poorly dub a foreign ad than to remake it from scratch. If you're talking about ads where it's clear they're speaking English but it's still dubbed, that's because they try have more local accents. It's easier to sell a product to a Brit if it's a Brit telling them to buy it and not an American. Usually... | 1 |

Inside ambient air, its the middle ground, with it... | 2 |
97sfyo | Engineering | Why does the brake pedal seem to stiffen up if the car is off, but then go back to normal the second the car is turned on? | Power brakes are assisted with vacuum pressure either generated by the intake manifold (gas) or a pump (diesel). You usually get 2 to 3 presses of the brake pedal before all the pressure is released. If the engine is running, the pressure gets restored, otherwise it doesn't and the pedal gets still. | 3 |

TL/DR **Bad programmers and greedy server owners that push ads are the reason, there is no technical reason for it.** The simplest answer is that most modern browsers could resume download but the servers break it on purpose/due to a poor design. How downloading torrent works: * your cli... | 9 |
dw27ln | Other | How does snow work? Are there places where it snows once and it doesnt melt nor does it snow again until 1-2 weeks later? Or more? | It's not that it's not cold enough to snow. Snow is just like rain. But colder. It can be cold but not snow, the same way it doesnt rain for long periods of time. It is common to see the same snow for a week or more. It doesnt stay fluffy though, it develops this hard layer at the top. But if you punch or stomp through... | 2 |
j2kt3d | Technology | How do fitness trackers know that you actually sleeping but not just laying there resting, being awake ? Edit: Thanks for all the answers and the awards, I’m shook | They don't, they just make educated guesses. When you sleep, you heartbeat slows down and your body is more still than when you are awake. Even if you do move around when sleeping, you will be in one set location while when you are awake, you are more likely to be moving around the area. So what they do is see how stil... | 23 |

URL_0 At 20s you can clearly see what the background is and what are all the animated bits. | Oh I can begin an answer to this. In traditional hand animation, backgrounds are usually painted or drawn with a greater level of detail, because they presumably only need to be painted or drawn one time. The background is a separate piece of art than the character models. Characters, prop, and other moving items are d... | 2 |
8bowuv | Chemistry | Why does gum lose it's taste after chewing it for a while? | A big part of the flavour of gum is provided by sugar or some other sweetener, which gets absorbed by your saliva so it disapears from the gum. Also there is the brain. the brain is always looking for changes, in the input. Something that was tasted and deemed "safe" becomes less important so after a while the brain st... | 1 |

Usually white is the hardest coulor to keep clean as it stains easily. | Wild predators are not cotton tee shirts. Their saliva contains enzymes which begin the digestion process by...ugh! White kitty lick off blood. | 13 |
6sgeu9 | Technology | How does my phone never "freeze" while my computer "freezes" on a consistent basis? | Well, theres a few factors here. 1)Phones are pretty closed off from the outside- There are very few internet auto-downloaders, popups, etc. that function on phone browsers, unlike on computer browsers. Apps available for download are all (mostly) examined and approved before becoming available for public download. The... | 2 |
6cmt8c | Technology | Whats the difference in the manufacturing process of 30$ and 300$ headphones They both are headphones, they both make sound. why the price difference? | What you're paying for is the quality of the design, the quality of materials that would make the headphones more rugged and less likely to break under stress, the testing to make sure the headphones perform as designed, and the speed and efficiency of the manufacturing process (mass produced = less cost). For a qualit... | 2 |
bx1otq | Physics | Why do people tell you to turn off your phones when you're experiencing a thunderstorm? Do phones actually affect the possibility of getting struck by lightning? | Old wives tale, or new wives tale. Either way it doesn't affect the possibility of getting struck by lightning. & #x200B; Lightning is formed by ionized particles in the clouds moving to the bottom of the cloud and opposite ionized particles in the soil moving to the top of the soil. The general rule of thumb is that l... | 2 |
m5zb2x | Other | How can historians know the medical causes of death of people who lived before the existence of modern medicine? For example I was watching a documentary about Japanese warlords and it said that one of them died from liver cancer. How could they know that? | Ancient medicine may not be perfect, but it was not completely off either. They were certainly able to recognize signs and symptoms of patients, and make certain diagnoses. They may not have been able to cure cancer, or know exactly how cancer affected the body, but could identify it. Through observation, they could te... | 2 |
81a57i | Biology | why is it better to get some diseases when you’re a child (chicken pox for instance) because they are less severe in childhood than adulthood? Especially when you consider that children have weaker immune systems than adults. | it is because adult chicken pox tends to cause complications like pneumonia and encephalitis while childhood chicken pox does not. Adults’ immune systems are stronger and employ more antibodies (rather than white blood cells) than children’s immune systems do, which is what triggers the immune response and the subseque... | 3 |
g9kd8v | Biology | Why do medics keep you awake when you’ve had a traumatic injury? Why would being unconscious be more dangerous? | Also to add to the other comments, if the patient is actively *trying* to stay conscious and cannot, that tells us things vs the patient maybe resting their eyes or relaxing and falling asleep. We want to know if you just lost consciousness, and how difficult it is to arouse you - be it vigorous shaking, pain, etc. | 10 |
8suuzx | Other | Are stage names legal name changes? | The reason for the name change is because the Screen Actors Guild doesn't allow for duplicate names. You can't have 2 John Goodman's for instance. So many changes are informal but that's what they become known as | 2 |
l21t56 | Other | How does sunscreen work? I (kind of) understand the ones that form a physical barrier. But how does the other lkind work? It baffles me | There's chemical sunscreens and Mineral sunscreens. Chemical sunscreen products typically include a combination of two to six of the following active ingredients: oxybenzone, avobenzone, octisalate, octocrylene, homosalate and octinoxate. [Source]( URL_0 ). These chemicals create a layer on your skin that absorbs the U... | 3 |
jhbcjc | Technology | why do camera's make noise when they take a picture? Do they need to? | Old-school film cameras had a mechanical shutter that had to move, which created the "click" or "snap" that we've come to associate with taking a picture. Digital cameras absolutely do not need to make any noise at all, but there are two reasons they do so: 1. We expect cameras to make that noise, and 2. as a matter of... | 1 |
la233u | Biology | How does brain measure light received by retina, to send the signal to increase or decrease the size of pupil? | I hope this helps.. the optic pathway gets a little jumbled with names, but in general: Special cells on our eyes called rods and cones receive light, communicates it to the brain via the optic tract and nerves. From that point it gets processed via our cranial nerves and travels to a special nucleus called “edinger we... | 1 |
9mv442 | Biology | When people die from Overdose, would it be peacefull or painfull. | Asphyxiation itself is relatively painless unless you feel the effects of co2 buildup resulting in a desire to breathe. Although opiates reduce the percieved need to breathe and thus induce respiratory depression, leading to death by asphyxiation. You go from feeling good, not caring about anything, and perhaps doze of... | 3 |
iblc1o | Economics | Why is Apple's app store a monopoly but Sony's and Microsoft's console stores not a monopoly? | It's not illegal to have a monopoly. It is illegal to use your monopoly to compete dishonestly with other companies. So, the problem with Apple is not that it doesn't allow other app stores, it's that it uses app store access to prevent fair competition by imposing unreasonable conditions - such as insisting that every... | 4 |
5w508h | Biology | Why do we have to be sleeping to rejuvenate and re-energize? Why are these processes faster/more efficient when we're not awake? | When you sleep your blood pressure drops as circulation slows down and your muscles are paralyzed to prevent you from acting out dreams. Since your body is requiring less energy at this time, extra oxygen can be sent to your brain. In deep sleep your body is at its least active which gives it time to repair any small m... | 1 |
7zid34 | Culture | Why was slavery a common practice that occurred in every civilization at some point? It is considered inhumane by today's standards, but why was it considered to be ok in virtually every civilization at some point, regardless of the ethnic groups/people that happened to be enslaved. | Agriculture pros: you can grow more food than you need, creating a surplus of food, which you can use to build a civilization. Agriculture cons: without modern machines, crop breeds, domesticated animals, growing crops is labor intensive hard work. Agriculture with slavery pros: you can build a food surplus and only ne... | 4 |
9iosur | Biology | Why aren't there any common multi-headed animal? Wouldn't having multiple heads add survivability? | Imagine you have two cars, they don't store the fuel, they're always using it right away. They're identical and you give them the same use. What would be a better option: (a) Maintaining both cars, even though you have to refill both, or (b) maintaining only one car? A similar problems arises with having two heads. I'l... | 15 |
o640pw | Biology | How does jumping/landing/falling "correctly" not give your brain concussions? Googling this gives stories about people actually getting concussions on trampolines or doing parkour and that's not what the question is. The question is, if your brain's the consistency of tofu, how does bouncing around "safely" not just bu... | There is a layer of cerebrospinal fluid surrounding your brain that cushions minor impacts. | 5 |
5ovbsl | Biology | How is it that cannabis has so many different 'strains' which change the appearance and other characteristics of a particular plant? Do other plants share similar significant genetic variations? There are countless strains-all with different looks, smells, tastes, colours and other variations. Obviously there are other... | Variability in the genes of different members of the same species is extremely common of life in general; it's the norm. And that's a benefit since it allows for adaptation if their environment changes which in turn helps ensure the survival of the species as a whole. For example, if some disease came along and everyon... | 3 |
ag0ot3 | Technology | Why can’t sound engineers create a consistent volume level throughout an entire movie or TV show, it’s either too quiet or way too fucking loud at different times? | They can, it is just bad. Part of what makes a show or movie better is to have dynamic range in the sound. It makes things more like real life and most of the population enjoys the movie more. | 4 |
6g4n5k | Biology | Why do worms always crawl on the hot sidewalk to die? | Generally they're crawling out because the soil is saturated. When the soil is saturated, they can't get enough oxygen. | 2 |
6xf8xc | Biology | Having high blood pressure is bad, but having really good cardio means your resting heart rate is lower. Doesn't that increase your blood pressure since your heart beats harder? Why isn't this bad? | Your heart is the pump that circulates blood. In order to maintain the necessary blood flow it either pumps faster or pumps slower. Assuming everything is equal and one persons heart pumps at 80bpm and another at 60bpm. The pressure is the same because the flow rate is the same. Now blood pressure usually increases whe... | 2 |
cagfl0 | Culture | Why do single person restrooms often have a male and female one? I don't understand because it's not like there's gonna be anyone else in the bathroom but you. Also they both have a toilet and sink so there's basically no difference exept if there's a men's urinal, which you don't have to use if you don't want to or ca... | Both men and women are gross when it comes to public restrooms. That's not something associated to one gender. I would say the actual answer is that people expect public toilets to have a mens and a womens, societal standards calls for it. If they didn't put labels people would probably complain about men going in afte... | 1 |
gma6tr | Chemistry | How can canned meats like fish and chicken last years at room temperature when regularly packaged meats only last a few weeks refrigerated unless frozen? | Louis Pasteur would like to have a word with you. Canning basically sterilizes the food eliminating any bacteria and barring any bacterial activity it is shelf stable. Canned food basically has a lifetime based on the lifetime of the can it is in. Note the canning process basically cooks the food to rid it of bacteria ... | 13 |
6c2xac | Other | Why are women athlete outfits far more revealing than those of men? | [Are]( URL_1 ) [they]( URL_0 ) really, though? TBH it probably has more to do with what is socially acceptable than anything else. I'm sure a guy would be free to wear clothing similar to a girl, like extremely short shorts and a crop top, or a full bathing suit, but he won't because it's not normal right now. FYI, in ... | 6 |

8c9isq | Technology | What happens in the background while we see the "loading screen" in video games? | Generally, Data is being loaded from the harddisc into the ram memory. RAM is a lot faster than your harddisc, even if its a SSD, it just has the handicap of losing all data when its unpowered. So we store data on harddisc's that are slower and cheaper, but retain data without power. Then when we need it, we load the d... | 2 |
bnhoft | Physics | If photons travel with constant speed and direction, why does light fades away over distance ? Sorry if this title isn't grammatically correct, English is not my native language | Imagine a shotgun being shot at a target on a wall from close range - the scatter of bullets is close together. Move further back and shoot again - the bullets are scattered further from each other. Now imagine the bullets are photons and the target is your eye - the further away the shotgun (photon source) gets from t... | 2 |
