Is there any merit to the idea that exposing yourself to germs strengthens your immune system?
|
[
"Your immune system, every time it beats off an infection, stores information about that infection in it's \"memory B-cells.\" That way, if you get reinfected, your immune system can say \"aha it's you again! I remember your secret weakness from last time!\" instead of having to figure it out all over again. It doesn't have to be a big infection for it to work; even a small infection will trigger and immune response. So yes, the more germs you are exposed to, the bigger your memory banks will be, and the less likely you are to get a serious infection from any of those germs. Edit: yes, I did say \"beats off\""

How does my fingerprint scanner on my iPhone work through a plastic bag?
|
[
"Because it's not a fingerprint scanner, it's just a camera. Advanced fingerprint scanners use high resolution CMOS sensors, pressure and temperature sensors, and a myriad of other tricks to detect an actual finger against a simple printout of your print. The scanner on phones and laptops, and other cheap consumer scanners are barely more than a cheap CMOS and a cheap lenses, with some software to do the processing. If the plastic bag is clear, it should work as well. A printout of your fingerprint will most likely work as well."

The reason why NSAIDS are ineffective at reducing symptoms of diseases like Psoriasis?
|

why it always seems like people wake up before the best part or climax of their dreams.
|
[
"Until a better answer shows up, I believe I've read on this very forum, that it has to do with the fact that the \"best part\" just so happens to excite you so much, that your brain activity increases and you therefore begin to awaken. Another aspect may be that you don't remember dreams in which you didn't wake up during the middle of them. However when you do wake up during a dream you are more likely to remember it. So you don't always wake up before the best part, you just don't remember the dream at all."

How can someone be immune to the laws of a country simply because they have diplomatic immunity?
|
[
"Because the country that they represent have been extended that courtesy for their diplomats by the host country. It's a common arrangement so that diplomats don't get blackmailed by local police or politicians. The host country can always expel a diplomat if they don't want them there.

Why do the creatures at the deepest parts of the ocean look so different from that species we normally see?

"A huge pressure. For anything to be able to withstand it you need either incredible skeletal structure, or massive skin and muscle mass.

How does Google Maps know when there's little, medium or high traffic on roads?
|
[
"I don't know if you noticed, but Google figures out pretty quickly where you live and where you work: that's because it activates the GPS on your phone in the background and registers your location quite frequently. If you are driving, Google can interpret the GPS location of your phone as an indication of no traffic (phone moves at speed close or past the speed limit for that road), light traffic (phone moves at reduced speed) or high traffic (phone doesn't move at all for prolonged periods of time). Using the data from many phones, the results are pretty reliable. The algorithm uses traffic status when selecting a route to try to reroute the incoming cars to other roads in which the traffic situation is better, both to help you get to where you're going faster and to help clear the traffic jam by not feeding it with other cars."
] |
[
"\"Would you like to share your location with Maps?\" If you click No, then it pretends it has no idea where you are (which is probably true). If you click Yes, then you're telling it where you are for TWO purposes: 1. To place you on the map 2. To relay this information back to the server so it can see where *everyone* is on the map. It can see what road you're on, what lane you're in, and most importantly, how fast you're going in comparison to the speed limit. It uses this information to predict which roads are backed up and which ones are not."

Why and how are power plants designed so they can't power themselves?
|
[
"The plant isn’t technically incapable of powering itself—it’s incapable of running without a grid connection. That might sound like a distinction without a difference, but the plant requires a connection to the grid not to *receive* power from the grid, but to *dispose* of power on the grid. The nuclear plant requires a fraction of a percent of its own power to run. It simply cannot throttle down that low. Without a million kettles eating 99% of its output, it must shut down. If it kept running, the excess electrical power has to go *somewhere*, and without the grid as a safe outlet, the generators would destroy themselves. Shutting down the reactors and turbines is generally generally okay, because it has back‐up diesel generators to power the cooling systems and whatnot, but then the generator room floods and you’re in trouble."

How does evolution explain an animal developing the ability of venom attacks? Like a Platypus?

"As [this](_URL_0_) link will tell you, many venom systems started out as something entirely different whether they be digestive enzymes, proteins to help fight bacteria, etc. A mutation occurs and suddenly that enzyme/protein/etc is present in the mouth/claws/etc, and it gives them an edge to catch prey and just generally survive. Each instance of venom in an animal seems to have developed on its own, so you aren't going to find two for the exact same reason. We are still learning about the subject though."

"Because some of them are really poisonous and can bite you and poison the shit out of you.

Why is gold valuable? For how long will it continue to be valuable?
|
[
"Gold is valuable primarily because people believe that it is valuable. (It does have some practical uses in jewelry and electronics, but these things aren't nearly enough to support its current price). It will probably continue to be valuable, because gold being valuable is a significant part of our cultural identity. The question is whether or not gold will continue to be *as* valuable as it currently is. This is unlikely; eventually, the price is going to stop rising. Investing in gold is just betting that the price will rise enough before you cash in. e: I didn't answer \"would it be smart to invest\", and there's a good reason for that; any advice would necessarily be wrong. Remember, the price of gold is entirely dependent on what everyone thinks the price of gold ought to be. So if everyone knew that the price would drop when X, they would start trying to leave the market before X, and that itself would make the price drop."

"Transport is an important part of a country's economy.

As for gold, it is a precious metal. There are many precious metals but traditionally, gold has been the main choice. It is seen as a way of protecting investments. If the price of gold is going up, it means investors are scared and are trying to protect their money by investing in gold. When it goes down, the economy is healthy and investors are happily spending elsewhere. Currencies used to depend on the gold a country had, but I don't believe that is true any more."

Why can I remember the conventions of a new programming language or the methods of a new library with ease but spend hours memorizing facts in biology class to no avail?
|
[
"As a fellow student learning programming with ease and dying in biology, I feel your pain. I can't possibly explain for you without speculating, but for me it's because of the style. Biology is a very fact-oriented thing. You either know what allopatric means, or you don't. And you never get to actually use it, because you can't \"use\" biology terms. It's a field of science, not of engineering. For CS, you already know what these words mean, you're just learning new ways to apply them. It's about learning processes, not facts. And you use these processes constantly. Computer Science is a field of engineering, not science. Also, like RandomReddithead said, interest is incredibly important. And the method of learning is a pretty big deal."

[
"Programming, for anyone who's never tried it, is a very focus-intensive activity, and can be not strenuous at all. These things make marathon learning very useful, as new information can easily be picked up and utilized. (That is to say, you could learn how to use a function and then be able to use that function proficiently in mere seconds.) Compare that to math, which is hard to understand intuitively at most levels. Learning new math tricks takes time, so marathon learning is not a generally good idea in math. Or compare that to history, which must be learned sequentially and intensively for a student to create generate something worth reading. Or compare that to pottery, which is not a high-focus field and thus is not suitable for long sessions in which students may become bored. Many companies will use hackathons to get programmers or students to learn how to use a specific language, API, hardware, etc. Sometimes, hackathons are just \"hey, go work with other people and make something cool.\""

Allergies; and why the body develops them.

[
"Your body's immune system often causes your body to do less-than-desirable things. For example, when it's fighting a cold, it's your immune system, not the cold virus, which causes you to have a runny nose and sneeze lots. When something gets into your body which doesn't belong there, your body's immune system recognises that and gets rid of it. This doesn't just apply to viruses and other nasties. It can apply to things like pollen, or dog hair. When you have an allergy, what that means is that there are certain types of foreign bodies which your immune system over-reacts to - it doesn't just get rid of them, but it causes you to display some symptoms, such as sneezing, developing a rash, or being short of breath."

why does Adobe Flash Player need to update so much?
|
[
"Adobe (Originally, Macromedia) Flash is, by Internet standards, a very old format. It comes from the days where every byte and every CPU cycle was very important. This meant that it used various tricks to save space and computer effort. The programming to work with these tricks is complex, and complex programs have places for bugs to hide, and hide they do. There are bugs that have always been there, waiting for someone to send the program a strange flash file and make it do something wrong. There are bugs caused when modern programmers forget they are working with old code, and are not 'defensive' enough, assuming that the code will do checks that were too (computer-effort wise) expensive decades ago. There really is only one solution for this - flash has got to go. There is no longer a need for it, as javascript and HTML5 can do everything that Flash does. We just need everyone who makes websites to delete all their flash garbage."

Is it better to brace your body or stay loose in an accident/fall?
|
[
"Obviously every crash is different and some things will work better in one situation than they would in another, but the brace position in an aircraft crash, or bracing against a car seat have a very specific purpose. In any collision there are multiple impacts. In an aircraft crash there is the impact of the plane hitting the ground, you hitting the inside of the plane (seat, floor, controls, whatever the object is), and your internal organs (biggest concern being the brain) hitting the inside of your body. The brace position is an attempt to remove, or at least lessen, the second of those impacts: you hitting the inside of the plane. By placing your body against the seat in front of you, or against your legs (depending on the position used) you are already against the object you are likely to hit and will therefore push against it instead of impacting it."
] |
[
"To put you in the safest position possible in an accident. In a car the safest place is in the middle of the back seat, with a lap and shoulder belt.

"The ingredient in mint gum that gives that cooling sensation is called Menthol. The tongue can not tell the difference between Menthol and actual cold temperatures so that's why they feel the same. As a side note, capsaicin (the active ingredient in spicy food) is why our mouths feel hot. Again, because this chemical tricks our tongue into thinking, it's on fire."

What's the significance and possible implications of all these nations joining this new China-led bank? (akin to the World Bank)
|
[
"I guess we will wait and see. The obvious one is that there is an alternative bank for governments to turn to. Some countries can't get IMF and world bank loans. Other can only get them with a lot of strings attached, such as: reduce a country's debt to GDP ratio; reduce government spending; lower tariffs; allow imports in; enforce global copyright on pharmaceuticals and entertainment; pay back your previous loan; high interest rate. Now they have a new place to apply to, with different strings. Also IMF and world bank loan often bind the borrower to use western development companies for resource development and infrastructure building. With a Chinese lead bank, Chinese state owned resource companies and development companies will get a better shot at contracts. Edit: Another thing is China's foreign reserve is full of US treasury bonds, which is not paying any interest at all right now. Putting some of it in the new bank will probably get them a higher interest rate than 0, even if they lose some of it."

How did some animals (lizards etc.) get an ability to regenerate limbs evolutionary?
|
[
"All species have the capacity for regeneration, some to a higher extent than others. What you are referring to is called autonomy (self amputation) and in most cases it was developed as a defence mechanism that allowed an animal to escape by sacrificing a limb and then regrow a substitute one (albeit imperfect one in most cases, as they can and do regrow differently to the natural ones, e.g. Deformed in some way). A good example of this are certain lizards that will leave a part of their tail as a decoy (it will continue moving after becoming detached) to flee from a predator. The tail will grow back, however it will not have the same bone structure as the original one as it will be mostly replaced by cartilage. Edit: a very good example of this in humans is liver regeneration. A human liver will regenerate back to its original size even if 80% of it is removed."
] |
[
"Because their physiology (body make-up) is completely different. Worms are invertebrates, meaning they don't possess a single bone in their body. Snakes are reptiles (belonging to the vertebrates). That means there are numerous evolutionary steps between them. IIRC, snakes do stretch their bodies a little but because of their spine, they have limitations on how much they can expand or shrink."

Why do our voices sound robotic when we speak into the fan?

"Because the fan blades reflect the sound back at you, like any hard surface will. The difference is the fan has gaps in it that are are whizzing past. So you're getting hard surface, gap, hard surface, gap and so on many times a second, and your voice gets reflected back with a similar on/off/on/off pattern.

"No. There is no practical reason why they cannot combine. If you watch \"Gangs of New York,\" you can see practical reasons why combining police forces and having uniform laws are a plus.

What constitutes a "side effect" in contrast to the effect in drugs?
|
[
"A side effect is simply something outside the intended purpose of the drug. Even if it happened 100% of the time, it can be considered a side effect. For example, a common allergy drug (diphenhydramine) also has a side effect of making one drowsy. You're buying it to be relieved of allergy symptoms, so the drowsiness is a side effect. But the side effect here is strong enough that the same drug is repackaged and sold as a sleep aid, in which case allergy relief is a side effect."

Most of the time it has nothing to do with the disease but rather on the mechanism of action of the drug."

Why are video game prices dropping quickly this year
|
[
"games industry has seasons. During summer there arent many releases and as the xmass is closing you have many \"holidays\" eg. days of free time but not friendly weather so people tend to stay at home and play games. And that means that sales (price reduction) is a good motivation for customers to buy that game and acquire some of the market share. also the industry is in the last decade starting to accelerate so you see every year more games that come out and that means a bigger competition so the publishers/developers need to release every 12-24 months a AAA game (CoD, AC, sport titles...) to hold their profits. the hardware industry (PCs components, PS, xbone...) is also relevant, because new technology means better graphics and performance so the game industry needs to innovate more eg. develop new games/versions (remaster, graphics dlc...) also black friday and whole december are times when this industry makes the most money (for instance book industry is most profitable during december)"

Why does sand stick to everything even though it doesn't feel sticky?
|
[
"Sand sticks to things in many ways just like flour does. Flour particles aren't sticky at all (while dry), but small enough to be caught in tangles of fabric fibers, attracted by even the slightest charges, or \"grabbed\" by microscopic droplets of water or oil (and the human body is literally covered with oil-drop and water-drop emitting organelles: sweat glands and sebaceous glands). Flour is many times smaller, so more sticks of course, but at the size level of a grain of sand a human body is covered in a rough shag of fibers, and sticky oil and water films. None of these hold on very tightly, but tight enough to resist gravity and most movement, so the sand doesn't just fall off when you stand up. Brushing the area is more forceful, and tends to knock off every grain of sand hit - but again, sand is so small it can \"hide\" in the fabric or get missed by a rough hand brushing."

When cars are towed, how does the owner know that it was towed rather than stolen?
|
[
"Cop here: A lot of times there will be a sign that tells you what tow company tows from that area. We do still get a lot of calls about stolen cars that end up being towed, though. In my state, tow companies are required to submit every car they tow into a database that's searchable by police. 9 times out of 10 when you call 911 to report your car stolen and give the operator your license plate, they'll be able to tell you where your car was towed to. I've had a handful of cases where a car was towed and didn't get put in the tow file (usually repossessions). In those cases we'll do a report, the car will be entered into NCIC, and then we'll find out later it was towed and just have to close the case. Again, this is my state, I can't speak for states that don't have this system."
] |
[
"It means your car broke down and wasn't abandoned. Your hazards will only work until the battery dies. It let's the police know your intent to come back to retrieve the car. As long as it's off road, or not on private property you may buy yourself a few days without getting towed."

How come steak can be rare but ground beef must be fully cooked
|
[
"Steak is relatively dense, so bacteria tend to be on the surface, which you will be subjecting to a lot of direct heat. If you grind the meat up, then you potentially allow any present bacteria to spread throughout the material."
] |
[
"So pork has an issue of tape worm inside the meat. Unless it's cooked to 140-145F then the worms can hatch. As for chicken the bacteria can penetrate the flesh, so it has to be cooked high enough all the way through. The bacteria in beef don't penetrate, so it doesn't have to be cooked as hot. Beef can be eaten raw if it's freshly cut and not dirty since bacteria hasn't had time to spread across the meat."

How do PC games have "bad ports" when the games themselves were made on them?
|
[
"Games made for consoles: * Are using different technologies, so a lot of code has to be rewritten for PC. * Have fixed hardware that developers can optimize for. On the other side, PCs have a variety of different hardware with different performance, and software can vary too (operating systems, drivers, etc.) * Have fixed screen resolution and FPS, computer games that have to support many different monitors usually do not. * Have different controls. For PC version, keyboard+mouse must be added and it often sucks, because developers focus on gamepad (Dark Souls, I'm looking at you). In addition: * Many game studios do not care and they outsource ports to cheaper external companies, some of them really suck. * Ports often have to be done quick and have lower priority then console versions due to different revenues on platforms. But it is an infinite circle, revenues on PC are low because many ports suck."
] |
[
"Two reasons: 1) It takes a lot of effort to design a game in such a way that it works for console and PC. Normally a fair bit of tweaking is involved in making sure it's cross-platform. 2) Often the game development pipeline will be funded by a producers/companies who want the game to be strictly tied to one console. They'll fund the making of the game, and in return the developers will make sure that game's only accessible on one platform. That's why you rarely see games that are available on the Wii/Switch also available on on PC."

Why did people lose their retirement funds during the recession? Wasn't it protected or guaranteed?
|
[
"Sensible investors didn't lose anything. The proper way to save for retirement is to automatically rebalance your portfolio as you get closer to retirement age. Basically there are some investments that grow faster, but can also lose faster in a recession - like stocks. Then other investments grow more slowly, but they're much safer and don't go down in a recession - like bonds. Finally there are other investments that tend to have different cycles than the stock market - like real estate and commodities. A correctly-set-up retirement account will be mostly stocks when you're young (so your account can grow the most) and then converted to mostly bonds by the time you're close to retirement age. When you hit retirement age, your account should be 100% safe investments like bonds Unfortunately, millions of people didn't invest this way - so if they had their retirement in stocks they gained more as they approached retirement but then suddenly saw their portfolio lose half its value."

"They didn't. The Federal Government implemented the Federal Deposit Insurance Corporation to make people trust the banks again. All banks are forced to pay the FDIC for its protection, and the benefit is that all accounts of up to $100,000 are 100% ensured against bank failure. If the bank goes out of business, your money is still safe because the FDIC will pay it back. Back when people still trusted the government, this worked perfectly. Nobody trusted the banks, they got us into that mess in the first place! But the government? We vote for those guys, and we can kick them out if they lie to us and steal our money again."

Do musicians get paid everytime one of their songs is played on any radio station at any given time?
|
[
"They do get paid royalties, but it's not a one-to-one pay out (i.e. you typically do not get paid in relation to each time your song is played). Basically radio stations report which songs they've played during what programs to performing rights organizations which then decide how to divide up the royalties appropriately and give each (registered) composer/publisher/author a fair share based on play-time of their music during a given period."

"Nothing gets 'lost' per se, that mass represents the energy (and some other stuff) that was originally bound up in the Hydrogen atoms.

Why is it a bad idea to put dental glue for braces all over your teeth to prevent damage or for less maintenance?

[
"It's easier and less expensive to just brush and floss, but even if you could encase your teeth in a protective shell, you would still need to brush and floss to protect your gums from disease. People with crowns, which cover the exposed tooth and cannot get cavities, can still develop cavities around the edge of the crown near the gumline."

"SecureThruObscure explained the shield, but not what the light itself is for. The light is used to harden a special type of glue which is used on your teeth. It is designed to turn to cement only when exposed to the super bright light, which is why the dentist needs such a bright light which would hurt his eyes if he didn't have the orange shield. It's basically because glues don't dry very well in the mouth, or very quickly, so this is an easier method to make the glue harden. The glue is often used to seal molars in the back of your mouth, they pour it in the cracks on the biting surface of the teeth to keep the cracks from collecting bacteria which can cause cavities."

What are the origins of the Baptist church?
|
[
"The original baptist church was started by a minister who had split from the Anglican church (the Church of England). From there it grew and spread, came to the new world, and became very diverse. Today it is not a guarantee that two baptists from different congregations (this means a church community) will believe the same thing. The most unifying theology (belief) of baptists, and what they get their name from, is their believe in \"believer's baptism\". In the Catholic church a person is baptized as a baby, here the belief is that the act of being baptized forgives the original sin that human beings are born with. The belief of many protestants, including baptists, is that one should be baptized after they are old enough to express personal belief in the church's teachings."

How does Albert Einstein's equation E=MC^2 relate to the creation of the atomic bomb?
|
[
"Atomic bombs, you see, work on a very complicated principle. To put it simply, a more-or-less \"normal\" explosion, but a VERY precise one, is used to start a chain reaction in a metal like uranium or plutonium(a radioactive, and thus unstable, metal.) The actual chain reaction...well, even I don't know much about the specifics, so with any luck someone else will fill you in. But what really happens at the end of the chain reaction is, a very very small amount of the _mass_ of the metal is transferred into energy. Einstein's equation, E = MC^2, is the equation that tells you how much energy this tiny mass gives you. In the equation, E is energy, M is mass, and C is the speed of light, and if you notice, C is _squared._ Since the speed of light is so unimaginably high, this means that even a tiny amount of mass would give you an unimaginably high amount of energy. So, it's not so much the creation of the atomic bomb, but how they work."

why we get goosebumps when we hear a particularly beautiful voice or a certain scene in a movie?
|
[
"The human brain is pretty amazing; it doesn't have to actually experience something to respond to it. Some external stimuli (e.g. a scene in a movie) can lead your brain to start acting like you are experiencing that scene in real life. This leads to the release of chemicals in the brain (neurotransmitters, hormones) which cause the body to physically react. The reason you get goosebumps comes down to evolution. A common response to fear, surprise, danger, and other strong emotions in mammals is to \"puff up\" their fur. This makes the mammal appear larger, and therefore more intimidating to what ever is making it afraid, surprised, etc. Do you have a cat nearby? Go scare it and you can see this in action. Now, humans have lost most of our hair, but we still have the brain pathways that say \"strong emotion = raise hair.\" So when we expose ourselves to something the evokes strong feelings, our body tries to puff us up like a terrified cat."

why do your pupils dilate when you take Psychedelic drugs?
|
[
"depends on the drugs or your definition of psychedelic. if you mean sensory hallucinations (drugs known as hallucinogens) then its because they generally act as stimulants (another word for drugs that overclock your brain) and since your eyes are now processing more light back at the cerebral end and your heart rate is up to feed your brain (as well as your eyes coincidentally), then you dilate (vasodilator and pupillary dilate) this dilation is therefore twofold - your eyes are literally able to take more light on, and also the nerves that stimulate your heart are closely related to the nerves that dilate your eyes. i would go so far as to say that the phrase \"you need to open up\" has a very literal meaning here, because your emotional openness is almost a gradient of how much you can activate and control/digest the info from this cluster of nerves, called your sympathetic and parasymphatetic nerves"

Why must an FCC approved device accept interference that may cause "undesired operation"?

"It means that the device has a low priority on the hierarchy of communications, so if something is interfering with it, tough titty.

Because amateur radio is on a higher priority than your wireless LAN, if your LAN gets shut down by the radio transmitter, you have no recourse. If your LAN is malfunctioning and messes up the radio transmitter, however, they can petition the FCC to order your WLAN shut down, because a lower-priority system is interfering with a higher-priority one."

Where I grew up, many kids had a \"pet\" cow as part of a 4H project. They took wonderful care of their cow, and showed them off in competitions. Then their took their cow down to the slaughterhouse and saw it converted into sides of beef they could sell or bring home and eat.

Using shampoo on your skin can cause it to become slimy because of the extra ingredients. In addition, they have a different pH level. Shampoo is more acidic. When you use body wash as shampoo, it will strip all the natural oils in your hair, and you seriously need those. Sidenote: This can also happen when you use shampoo too often. Every other day is ideal. Hair & Body wash is also a product that exists. I've never used it personally, but I can't imagine it would be more effective than purchasing them separately. Same with Shampoo & Conditioner in one."

Who notifies Google about newly made roads for their maps?
|
[
"There are companies specialized in this sort of thing. They monitor local government announcements, planning permissions, etc., and when they see a new road is being constructed, they will go and collect the data. Google's maps business is big enough for them to own some companies like that as a subsidiary, but sometimes they might just hire external companies to gather the data and provide it in a format that's easy to plug into the Maps database."

[
"Your GPS does not. The maps app does. How? Because countless other people are using the app and apple is using data from their travel to determine traffic conditions in real time."

What is the difference between being a line cook and a chef?
|
[
"Cool, that makes sense. I recently became the kitchen manager of my restaurant six months ago, the only reason why is because everyone else who worked there quit. But I make new recipes constantly and everyone calls me chef, but it feels weird."

Why does the U.S. always side with Israel over Palestine?
|
[
"There's no diplomatic way to say this — Israel is considered to be culturally similar to the US, it has a representative government with stable political institutions, and American Jews (who tend to support Israel) are an important domestic political constituency."

[
"Because the U.S. is allied with Turkey and doesn't want to piss Turkey off."

Why do those cheesy pictures that get shared on Facebook always looks so grainy and pixelated?
|
[
"They tend to pick up artifacts because the original image has gone through a chain of hundreds of computing devices which used different file formats and resolutions and so on. People do stupid shit with their files like opening them in Paint to edit them (adding/removing watermarks, resizing, adding/removing text, messing with color depth) and then saving them in a different format. A lot of image formats, like jpeg, are \"lossy.\" To save file size, a jpeg will essentially smooth out some of the fine details of the image, which gives you [artifacting](_URL_0_). If you pass an image around from one lossy file format to the next, it will artifact more and more each time its format changes, so the quality gets worse and worse."

"I would imagine it’s the same reason why cellphones cause airplanes to crash and gas tanks to blow up. They don’t. They just want people to pay attention to what they are doing instead of taking photos. Also flashes are super annoying. Could you imagine trying to enjoy a painting in a dimly lit room and suddenly 30 bright lights flash in your face? Now you have little light blobs burned into your vision ruining the rest of you art viewing for a few minutes. Also a lot of art has glass over it so a flash would just reflect off and look terrible anyway. Ever tried to take a picture of an aquarium with a flash? Doesn’t work."
