While numerous acceptable factors including aldose reductase pathway, glycation, protein kinase C activity are true. . . . many of these... |
Why are most/all sniper rifles bolt action? Why can't they use a semi-automatic mechanism like most other weapons? | Bolt action rifles are lighter and simpler than semi-automatic rifles in the same caliber, and bolt action is an inherently more precise action type than semi-automatic.

How most animals get older even though cells "reproduce"? | A teacher back in high school explained it beautifully. She said, you know how when you make a copy of a document or picture using a copy machine, it looks fine, but then, when you go to make a copy of a copy of a copy of a copy of the original, over time, it just starts to looks awful and you can barely make out what ... |
why does army have to march instead of just walking normally? | It also keeps the lines from slowing. Ever been driving, and run into traffic for no reason?

How was Chris Hanson's show, To Catch A Predator, legal? | The clear intention to and tangible action towards committing a crime is enough.

What punishment would I face for unknowingly paying for something with counterfeit currency that I received from another unknowing person? | Nothing.

So is creating fake money with the intent of such deceit. But it a... |
why 'Diplomatic Immunity' is a thing. | Family members aren't covered at all; only diplomats that the host country agrees to accredit as official diplomatic representatives get immunity.

How did humans come to value Gold so highly? Just because it's pretty? | It has aesthetic value, but it is also malleable and ductile, letting us do a lot with it.

How our major cities would get electricity without using coal to boil the water at nearly every electricity plant? | I don't know the exact numbers, but 95% coal worldwide sounds really unlikely. Natural gas, petroleum, biomass, burning waste, solar towers, solar photovoltaic nuclear fission, wind power, hydroelectric, wave power, and geothermal are all ways to generate electricity without coal. Many of the above use similar technolo... |
Why can't a battery be charged instantly? | Heat, mostly. The chemical reaction that takes place causes molecules, the building blocks of the battery, to break apart and re-assemble themselves. This causes a lot of molecular vibration, which is basically heat. At a certain point, the heat can cause parts of the battery to melt or even vaporize, depending on how ... |
Why are countries like France , Italy and UK still considered superpowers when they do not dominate globally ? | UK and France are cultural powers due to the historic influence of the colonies.

Italy hasn't been a major nation for centuries. |
What is the purpose of imaginary numbers? | Imaginary numbers were invented so some guys could win math contests at old Italian county fairs. They kept going because the complex numbers, and not the real numbers, obey the fundamental theorem of algebra, which states that a degree *n* polynomial has *n* roots, counted with multiplicity. They're in your textbook d... |
If diabetic people can have dangerously low sugar from not eating, how can non-diabetic people go on fasts, or skip meals? | Having diabetes means your body can't adjust and adapt to sugar in your body. People who are diabetic need to manually inject insulin and start monitoring themselves. They essentially have to take over the task of the appropriate organs. Your cousin's body adapts on its own at finite levels we can't even begin to imagi... |

- Where do "royals" obtain their original claim of "royalty" from? | People got power through whatever means. Usually a combination of charisma and martial force.

Eventually some of the disbelievers will decide to believ... |
Why don't rich people fund projects themselves? | The real danger with personal projects is that, when you're in too close, you don't recognize their shortcomings.

Why can I have 500gb/month of bandwidth at home while I'm only allowed 2gb/month of bandwidth on my phone? & What would they have to do to increase it? | Profit. All the major carriers sell their extra bandwidth to the Crickets and Go!Wireless companies who then sell it off for cheap .

Why is lobbying not considered bribery? | Lobbying doesn't necessarily involve campaign contributions. Many environmental groups have lobbyists that don't donate to conservative politicians, but they still explain why politicans should care about endangered species X and fund preserving habitat.Because if they ever tried to reclassify it as bribery, lobbyists ... |
Why are flat head and Phillips head screws both so common? Why is there not one go-to standard? | Everyone on Planet Earth already has screwdrivers for both. Any other new kind means you have to go out and buy another one for whatever wacky star/Robertson/Torq. Also, they are just fine for the vast majority of jobs. if is't not broken they don't fix it. The other's definitely aren't better enough to merit an overal... |
When it asks what your race is on a form, why is Hispanic/Latino asked as a separate question? | When I was applying to colleges in the 80's, this stuff was just getting started.

Why do sharks, being predators, have eyes on their sides? | If i'm not wrong, they use more other senses to detect their prey than their eyes.

They evolved eyes on the ... |

Why do some wind turbines not spin, even if there's enough wind to turn the blades? | Also, note that not every turbine in a farm is in the same wind path - some may be shaded by hills more than others, or not get as much wind flow when it's blowing in certain directions.Turbines can be damaged if they spin when the wind is too powerful. Also, it may just be maintenance, or the demand for electricity is... |
In terms of polygons in animation and video games, why are triangles used more often over other shapes? | I'm not entirely sure but basically i think it's because they are coplanar which means no matter where u place all 3 points to make up the triangle it will always be flat so there are no curves on the face of the triangle to mess up the textures. Edit: the YouTube channel computerphile has some really good videos on wh... |
How did game manufacturers of tabletop games ensure that at the opening of the game, theres equal probability of every player winning ? | The easy way is to tell the players to roll a dice to decide who's starting.

why does French have so many silent letters? | I question the premise of this question. Coming from French, I find English worse in this regard.

Why electronics require such specific voltages as 3.3v, 5v or 12v? | Yeah it's standarization, things that don't require a very different or concrete voltage can often be designed to work with those, if not then they use those voltages as a middle step and have their own voltage regulator to precisely deliver the voltage needed. In fact 3.3v is rarely used today because most of the thin... |
Why Is It Legal/Okay For A Clearly Pregnant Woman To Go To A Bar/Club/Concert And Drink/Smoke Publicly? | As long as it is legal for them to smoke or drink , there isn't much that can be done to stop them.

Why the Electoral College is still necessary. | When the US was formed, there was a debate one how the states should be represented.

How are online games like CoD or WoW able to coordinate information from so many different players so fast? | Computers are fast and the internet is fast. you can send data across continents in milliseconds. Even with that though the internet is not fast enough to provide 1 to 1 game play there's still delay between when you do something it and it actually happens for the other players under the best conditions. So whats usual... |
Why do different groups of animals have specific names (like pod of whales or murder of crows) is this scientifically useful? | As a joke, some English comedians used the phrase 'a flange of baboons' in a comedy skit on TV and the phrase passed on, possibly tongue-in-cheek, into academic journals. _URL_5_ You may recognize the gorilla once he starts talking.Clif Fadiman mentioned that a group of ladies of the night has been called a flourish of... |

The meat real... |
If sound travels better through water, why is it always quiet under water ? | It's easier to imagine by putting your ear against, say, a table.

Why is football the only one of the four major American sports in which the referees give big speeches about penalties and such? | They just explain it instead of the announcer .I wouldn't really call it a big speech lol", 'I should point out a lot of fans already think baseball umpires SHOULD have a means of verbal communication with the crowd/viewers because so many weird plays with complicated rulings can happen.I think it's the complexity of t... |
Why Don't Sponsors like Coca Cola Withdraw from the Qatar 2022 World Cup? | They are as evil as FIFA/Qatar and expect that the bad reputation of WC2020 will a) disappear once the games have started b) not be linked to their brand c) not matter at all, because most people don't care There are not many events where you can reach so many people at once like WC or Olympic Games. |
If I drink 10oz of an 8%ABV beer and 16oz of a 5%ABV beer, which one will affect my BAC more quickly? | Bartender/bar science engineer here. There are a couple factors to consider but the basic concept is it doesn't matter. The 8% will get you drunk slightly quicker but your blood is only capable of carrying so much alcohol at a time so by the end of an hour it won't matter. But in the course of 5 minutes the 8% will act... |
Why does USA elect their president based on who gets the most electoral votes and not by popular vote? | The US was founded by many rich and educated men. In a time where education was considered a luxury that only the rich had, most people were uneducated, especially the lower classes. The founders of the US knew this, and were afraid of the common people electing an incompetent man as president. The electoral college wa... |
Why don't people take the flu shot? | I'm from England, I'm in my late twenties. I have never had a flu shot and I don't know anyone who has had it.

Why do current gen consoles have amazing graphics and VR games still look like they're from 10 years ago? | For vr there are two screens instead of one and the frame rate has to be much higher for it to be comfortable to play.

How did they lift off the moon with such a small rocket? | The Apollo 11 lander was only a fraction of the weight of the entire rocket that took off from Florida. Combine that with the diminished gravity, add in a few thousand slide-rule calculations, and you've got it. |
How does marijuana help people that are sick? | It eases my pain from fibromyalgia. My fibro gets so bad that I can't turn my head and even the spray from the shower feels so sharp it's painful.

The most efficient way to utilize the 21 speeds on my bike. | If you actually want a calculation for your particular bike, it is going to be important to know the radii of each gear; so get out a tape measurer and report back all 10 measurements. It might that some of the combinations come very close to overlap , but it's unlikely they are exactly the same. |
Why do we eat only certain types of fish? | There isn't much of a meal to be had by eating a goldfish, and they don't taste particularly great. Otherwise they're safe to eat. |
if all cotton candy is is sugar and food coloring, why does it have such a distinct "cotton candy" flavor? | Cotton candy usually has some flavors added to it. The most popular is still vanilla, much like ice cream. Even when there's not, as cotton candy is made by melting dry, granular sugar and spinning it out, some amount of that sugar is going to caramelize a bit, which can add a distinctive flavor/aroma that's similar to... |
How does my dog immediately know if whatever I throw at her is edible? Why can't I do that? | It's not dog super-senses or anything. It's just that you've trained her. Every time you throw something at her face while standing at the kitchen counter or sitting at the dinner table, it's edible. A little puppy will be more likely to wait until it lands and sniff it to make sure, unless it smells really good or the... |
Why is Hitler considered the most evil person ever when there are other leaders who have killed more people? | Most other leaders have killed their own people. Hitler went outside the family. And he started a world war. And he wanted to eradicate a race of people from existence. And it's fairly recent. And I now feel like a douche for having to explain why Hitler was bad.its always worse when someone gets it on video. you hear ... |
With so many intelligent people in the U.S., why are the runners up for president not very smart? | Mainly because of the process of running for President is brutally invasive.

There are people who write parking tickets, euthanize animals, collect debts, kill people for their country, rule a country with iron fist or telemarket. Someone else will come and do the job if you don't. |
How do modern bombs like MOAB actually work? | In reply to your edit, to my knowledge the MOAB is pretty simple. It's just BIG, and it's designed to have a lot of explosive in a relatively thin casing to maximise the blast. The most complex thing on it will be the guidance system and the aerodynamic controls. By way of contrast, in the Second World War the UK made ... |
How do hackers get caught? | From what I've read, it's often not hacking mistakes that reveal the person's identity. People often overshare information about themselves. For example, the owner of Silk Road was identified because he discussed on some public forum creating the market, when he'd already shared information about himself on that forum.... |
If taxes are taken out of each of my paychecks, how come I need to pay taxes again every April? | You owe a portion of your total yearly income to the govt.

Why are there no permanent residents in Antarctica? | There's no possible way to raise food. Every scrap of anything consumable, including every once of fuel, has to be shipped or flown in at incredible expense. Every erg of power has to be generated on site. |
why do babies get medication based on weight, but adults don't? | Prescription dosages are often based on the individual it's being prescribed to - weight can be a factor, and if the dose is too weak or strong, it can be adjusted. This is even more true in a hospital setting. They just don't bother to do it with basic OTC stuff. With babies, the margin of error for medication is *ver... |
That feeling you get when falling asleep where it feels like you're sinking and momentarily jolts you back awake. | Read somewhere that it's a antiquated reaction from when our ancestors lived in trees, the jolt would stop them from falling out of said trees |
Could someone explain how the whole reddit protest/shutdown seemingly ended in a matter of hours? | The mods had the shutdown because they can't do AMAs with the sudden dismissal of Victoria, and they wanted answers from the reddit admins about how they are planning to settle the logistic nightmare of AMAs that Victoria has been so expertly handling. The answers from the admins made these mods realize the admins have... |
How can a password take hundreds of years to crack if it's secure enough? | aab", etc and so on and so forth. Eventually, it will try "hellothere" and crack your password, but it will take a while to try all the arrangements of letters/numbers/punctuation that come before "hellothere". Computers can run through those possible passwords very, very quickly, so when you hear about a password bein... |
why does your tongue rest at the roof of your mouth instead of the bottom? | Just another voice of the bottom-tonguers. Yeah you read that right. Seriously tho, my tongue rests on the bottom of my mouth as well. I do have sinus issues, and so I've breathed primarily through my mouth for most of my life, so that might play a part, but I know plenty of people who rest their tongues at the bottom.... |
The level of vitriol toward The Twilight Series | From a technical standpoint, the books are written poorly: The level of vocabulary is simple, except when the author is rather obviously thumbing through a thesaurus for synonyms. The message of the books is also problematic: The protagonist has very little agency and the attraction between her and Edward Cullen isn't ... |
What happened to the world economy | Banks' bet went wrong. They wanted bailout. I printed a lot of money and reduced interest rate. THE NAME OF THE GAME IS BAILOUT. THIS SYSTEM IS GOING TO COLLAPSE. |
How it come that pills knows where to go in human body? | When we swallow the pills, there is membranes in the sides of the stomach that can absorb chemicals from the pills.

Once it's in the blood it... |
How do wall street firms (like the one Mitt Romney ran) make money acquiring businesses and shutting down the entire operation? | In the early 2000's a PE firm called Wasserstein & Co bought an Oregon-based company called Bear Creek Corp which operates a mail order fruit & food company called Harry & David. They used borrowed money to buy the company, paid themselves a fee for advising themselves to buy the company, paid themselves a huge distrib... |
why do cigarettes help calm down anxiety? Is it something purely psychologic? | I haven't seen this mentioned here and I don't have a source, but I've read that deep breathing can be relaxing, which is exactly what you do when dragging the cigarette. Edit: here's a link with some relevant stuff: _URL_0_", 'Nicotine causes the release of dopamine, and I thought one other chem. This is how meds work... |
Why does hollywood produce these straight to video movies which are clearly terrible and how do they manage to get good actors in them? | No one sets out to make a bad movie on purpose. There are many, many pitfalls between script and screen. Actors are generally paid up front, so for Joey Pants, his wallet isn't impacted if the movie turns out to be a turd. Some huge actors can demand percentages on the movie's profit, but most of their salaries aren't ... |
Why are men's pant sizes in measurements and women's pant sizes in generalized numbers? | Men's clothes aren't safe either. _URL_1_ Women's sizes, at one point, were inches minus twenty. So if you had a 28 inch waist, you were a size 8. It's a much bigger mess these days and varies wildly from brand to brand.While nowhere near as bad as women's clothes, even men's clothes have the same problem. I have three... |
How does your body know where to burn fat from? | You don't burn fat from specif areas. If you notice you are working out one area and it has less fat its probably because you have globally lost fat in cells and those muscle are larger and easier to see. Everyone is a programmed way to use fat cells when you need them for energy. So your liver will break down fat into... |
How can so many mobile games get away with clearly ripping off copyrighted material? | A lot of times the games aren't regulated very well and the companies that own the apps don't always care. I mean when have you heard of it making news about apps using copyrighted material? It just isn't monitored.This not much of an explanation but Riot games has been going after these rip off companies lately |
Exactly how screwed is the hacker/leaker of the nude celebrity pics? | Depends if Apple press charges which they will surely do. The celebrities sure can press charges but in the end it's Apple that's been broken in. It's like people use your shed to put their tools in. Someone came in your shed and copied their tools. You never provided insurance to your client, so they can't sue you for... |
Why is it righty tighty and lefty loosey? Was there ever a point when bolts tightened when twisting left? | There's no physics reason. This direction became the standard to avoid confusion, chosen because it's slightly easier for right handed people who are the majority. |
What's stopping new ISP's from popping up and competing with the monopolies some ISP companies have within major cities? Why isnt there more competition? | The current block appears to be that ISP's are not regulated under Title II and thus cannot be forced to open up their infrastructure to competitors as the telcos were required to do. While infrastructure costs are high, existing broadband ISPs have recovered that many times over. Third party gear works fine on these n... |
Why do we spend so much effort and money to explore space, if "over 95% of the oceans remain unexplored". Could there still be incredible things we don't know about? | If we don't eventually find another habitable world then we maybe doomed to extinction in the event a global cataclysm occurs. |
If the US Government prints money, and we need money, why don't they just print trillions and trillions of dollars? | The more money there is, the less it's value. Look at money like an object. The less of that object that exists, the more it's worth.Zimbabwe did this. It caused the collapse of their economy when things like a loaf of bread cost over 100 trillion dollars. Money is only worth as much as it has backing it up. Printing m... |
3d printers... what exactly do they do... I mean obviously they don't just make objects... right? Also how does it get done? | 3D printers generally use stacking layers to create objects. Say you wanted to print a cube The printer would lay down successive layers of squares until the height matched your specifications. It's the same as just laying sheets of paper on each other until you have a rectangle that's 8 inches high.heres one you can s... |
Why do many parade uniforms have a chin strap that rests on the mouth not under the chin? | Hi, I'm a drumline director. In marching band uniforms, percussion wears the strap in their mouth because of vocal commands; if the strap was under the chin, the movement of the jaw would cause the plume at the top to move back and forth. Wind players obviously can't do this :) |
What Is DRM And Why Do People Hate It? | DRM, or Digital Rights Management, are tools and road blocks put into software as an attempt to make it impossible to pirate. The problem with DRM is that it frequently punishes legal purchasers far more than those who pirate the software/movie because the cracks used to do this usually strip the protection measures ou... |
How does Putin stay in power and how come he keeps being re-elected? | Sham elections, rigged elections, threats of violence, and self-preservation. Sure, you might *go into a polling place to vote*, but there's nothing to say your vote will get counted. That, or it gets counted **and** someone slips in a few hundred pro-Putin votes. Or hell, you vote *against* Putin, somebody notices you... |
How come the sheer power of dreams is enough to make me ejaculate in my sleep when the same thing takes considerable physical effort when awake? NSFW I guess. | Have you ever heard the term 'the brain is the largest sexual organ'? This is the proof. |
Why do gaming companies not re-make old consoles and re-release old games? | > but the technology is old and easily reproduceable. It's actually not as easy as you might think. Manufacturing digital hardware requires very specialized factories. They couldn't just take one of their Wii-U assembly lines and make N64s for a week, it would require a plant specifically for N64s.

Why doesn't MADD provide funding for sober rides/taxi services? | Great question. My question is why doesn't MADD stop focusing on alcohol and broaden their scope to all types of dangerous driving? Driving sleepy is much more dangerous than being drunk . Too many DUIs seem to be just easy ways to get revenue. For example, the guy who is .04 and gets stopped when his tail light is out... |
Why don't we have graduated brake lights? | The biggest issue would be that different cars would have different scales. A volvos level four might be just as bright as a nissans level 10. 10 being the max. You'd have a hard time gauging how hard anyone is braking. |
If something has its colour because light get deflected, does that mean that an object in a fully dark room has "no colour"? | Yes. Color isn't even a true physical attribute. Color is our body's interpretation of a certain band of electromagnetic waves. If there are no waves available, then there is no visual perception, which means there is no color. |
How did Skyrim keep track of everyone's actions, movements, interactions with the environment etc. The computation seems mind boggling! | It didn't. The world only exists a few hundred meters around you. Once you get too far away from NPCs or items, they're removed from the game to save on processing power. |
If people with one eye have no depth perception, how come I still have it with one eye closed? | It's actually a misconception that having one eye means no depth perception. The brain has a lot of methods to determine depth, and having a secondary eye is just one of them. Motion is a big one - try closing an eye and looking at static objects with your head still, and then look at the same objects while moving your... |
When I "google" passwords I use for various websites (usually porn) I get lots of hits for databases that include both my username and password - wtf? | I guess I'll be the first to admit getting a cold sweat when reading this headline and quickly googling my most common usernames and passwords. *Phew* - no hits. |
When we take medication, how does it know where to go to heal us or where we're hurt? Is there any possibility that goes to another place that it shouldn’t? | Like /u/MultiFazed said, typically it enters the bloodstream and goes most places. Many medication target specific receptors, however, so the effect is limited to specific regions . Side effects other represent off target binding etc. There are several simple and complicated ways to make medications more 'selective' in... |
Why does butter on toasted bread taste different than butter on non toasted bread? | Could also have to do with how toast tastes differently than bread, but I'm just spitballing here. |
