IQ tests. How can someone of average or higher than average intelligence design puzzles or problems that only geniuses can solve. | Psychology degree here. Truly 5 year old explanation: It's not that only a genius could solve such a puzzle, it's how quickly and accurately such a puzzle is solved. Given enough time and scratch paper anyone could solve even the most complex math problem. The faster one does so accurately the more 'intelligent' they are at that thing. IQ tests measure your ability to store, randomize, recall and reflect information within a time frame.Even 72 offsuit wins some of the time. |
Why do video games play smoothly in real time but animations can take hours or days to render, even if the game is more graphically pleasing? | Films are mostly ray traced. Ray tracing looks at each pixel in each frame and traces the light ray for each pixel back to its source to figure out what color and how bright that pixel should be. Ray tracing produces the highest quality and most realistic results but at a tremendous computational cost. Last I heard, it's generally accepted that real time ray tracing at high resolution just isn't feasible. GPUs, the specialized hardware that makes games look good, use fancy math and some observations about how we perceive things to cut corners in drawing each frame. This allows games to run at high frame rates at high resolution, but the trade off is well, reality. For instance, a ray traced mirror requires no special handling, while a GPU handling a mirror might need to be programmed to reflect a player's face, but only when a player is looking at it, and otherwise just make it look shiny. All that said, why one game or animation looks better than the other often comes down to the skill, time and budget of the people putting it together. |
Why is having an asynchronous snapshot of an object either quite ineffective or costly, to keep up to date algorithm-wise? | Tom bought a $5 item" assumes that those two things happened in order, if the snapshot missed the "Tom deposited $20" but recorded "Tom bought a $5 item", when the snapshot was restored it would look like Tom had a negative balance. So, to fix this, you need a more sophisticated transaction. Maybe one that keeps track of ordering too. So now, instead of just a bit, you need list of transactions in order too, so each thing you do is recorded sequentially while the snapshot is going on, so your snapshot is valid. However, this is no longer in a normal fast data format like a tree datastructure. So you need maybe a duplicate of the database that keeps the live fast searchable version, and one that keeps the transactions one. Thus, you need two copies of the database, one that is live and searchable, and one that keeps track of the all the transactions that happen while the snapshot is being taken. So taking the snapshot so it doesn't either require the database to lock or get corrupted requires two medias running in parallel and some sophisticated algorithm for tracking what is going on. This new system is much much more complicated, and uses more bandwidth, which requires more expensive hardware. TL;DR snap-shotting is sequential while databases are hierarchical. snapshotting a live heirachy causes out-of-order corruption, so fancy algorithms that handles both heirarchy and sequence are required. |
How are we to tell which nutrition recommendations are true when there are numerous contradictory reports every few years? | As a layperson you probably can't. You'll need to rely on an expert, such as a nutritionist that you hire to make a meal plan that's a perfect fit just for you. If you can't afford that, a number of countries around the world have hired a team to create a 'one size fits all' meal plans. [Here is a variety of resources from Canada]. [Here is another from America] At the end of the day, with the internet, you can type in anything you want to believe into Google and be given a source for it. Only experts, either privately hired or in government, can give you the honest straightforward truth. |
What is RAM and why is it important for computers? | Random Access Memory, also known as RAM. Essentially it works like really fast memory. Old hard drives and even their newer faster counter parts, SSDs, are somewhat slow at writing, the CPU on a computer, the device that does all the math in computers, need access to data fast in order to crunch numbers, far faster than any hard drive can give. So that is what RAM does, it acts as a temporary cache for a processor to just put stuff into when it needs to access various data and calculate with it. When you launch a program, all the files essential for the program's operation are put into RAM so that it can have all the data necessary to run the program.Think of RAM as your pockets and your hard drive as a suitcase. Your suitcase can hold tons of stuff, but its slow to get stuff out of it. Your pockets can hold a little bit of stuff but its quick to grab. Every program that your computer runs needs some of that "pocket space" and a bunch of "suitcase space". If you have tiny pockets or if you shove too much stuff into those pockets your computer runs slow. |
Why are fuel prices in the uk so high compared to america? | While price per barrel is set by opec, the us has a larger refining infrastructure and doesn't have to spend as much as on importing. |
Why don't they put solar panels on the top of electric cars to increase their driving range/battery life? | As everyone else has already pointed out the amount of electricity that solar cells the size of a car roof produce compares poorly to the amount of electricity a normal electric car consumes. Having a solar cell on the roof of your electric car will only increase its range by a tiny and negligible amount and trying to recharge a parked solar car with solar cells will take very long. However there are electric vehicles that can be powered by their Solar cells. They compete in race like the [World Solar Challenge] and look like [this] or [this]. They are extremely light and aerodynamic and consume a lot less power than your street legal electric car are covered all over in solar panels. Improving solar cells to the point where they are efficient enough to power a normal electric car seems not feasible from a technological standpoint and you can't build electric cars to consume so littler electricity either as they would be neither safe nor comfortable.The better idea, which people do, is build solar panels above parking lots, providing shade and protection from weatherThe amount of energy a solar panel would be able to generate is so small that it would not even matter for something that needed as much power as a car enginethe total surface area on the top of a car will only get about 2Kwh a day even on a very good day 2kwh in a Tesla will take you about 6 km Youd be better off transfering that solar panel weight to your garage roof and storing that through the day and then using that to charge your car at night', "They aren't efficient enough in that small of an area. However, i think every car should have a small panel for jump starting the battery. I'm surprised this hasn't been standardized yet. Edit: i don't know enough about cars |
If I were nearsighted, would my vision be blurred when looking in a mirror at something in the distance? | Yes, there's no difference to your eye between focusing on an object 12 feet away and focusing on a reflection of an object that is 6 feet away from the mirror when the mirror is 6 feet from you. The reflected light is still traveling 12 feet. |
Why does the window of my oven have thousands of black dots? | I'm assuming you're talking about a microwave. In that case, since microwave radiation is good at heating things up and cooking flesh, it can also cook your flesh. Microwaves can travel through any solid object too. So if you had a clear window on your microwave, you would be getting exposed to some pretty strong radiation. Enter the black dots. They're placed in the grid you see on your oven because those dots are material that can block microwave radiation. The microwaves have a certain size that cannot pass through those dots in large enough amounts to hurt you. They're basically blocking the microwave from killing you, and you can also see your food as it's being cooked! edit: Seeing as how I was only somewhat correct, I'm going to clarify the dots. The dots are not painted on in the case of a microwave. They are literally woven into glass panels so they can offer a good barrier to radiation. On my 10 year old microwave, the dotted glass was literally the only glass separating you from the radiation. On my 1 year old microwave, the dotted grille is woven directly into a glass panel facing inward, and then there's another layer of clear glass panel facing outward. It might be safer that way since there's a buffer zone between your face and where the radiation stops.The rear windshield of my car has them for the same reason? |
Why are (seemingly) all primes +/- 1 away from a product of 6? | Let's go a step back first. Do you remember when you first learned primes in school? Many teachers like to show it with a 10x10 grid that's have the numbers from 1 to 100 on it. The teacher then proceeds to tell you to cross everything out that can be divided by 2, then what can be divided by 3, and so on. After the first step with the 2, you'll notice that it's always one crossed out, one not **, one crossed out, one not **, and so on. Now, if you multiply something with 6, you're indirectly multiplying it by 2 and 3, right ? This means that you'll always land on a spot on the grid that has been ruled out as a possible prime already, because it can be divided by 2. However, there's a chance that there's a prime to the left or to the right **.Primes other than two have to be odd. All numbers have to be +/- 0, 1, 2, or 3 from a product of 6. Those 0 away are divisible by 6 and not prime. Those 2 away are even and not prime . Those 3 away are divible by 3 and not prime . That leaves +/- 1 as the only remaining options. |
Why is the Hunger Games so popular? | Is this the first time you've read a book series you only semi-liked which turned into a move franchise? I read all of the twilight books and slightly enjoyed them. They weren't great, but they were entertaining. The movies are shit and people go apeshit over them. It's because it's marketed really well and get's young people going. The hunger games is very similar, only the books were much much better than twilight. |
Why do most female athletes wear revealing clothes compared to male athletes of the same sport. | I'm not sure which sports you have in mind, since I do not believe your comparison is accurate. At the elite level of international sports, they are in it to win it. Sports governing bodies often have very strict rules on what players may or may not wear during competition. Sometimes this is a matter for the organisers of individual events, who impose additional requirements - such as the [Wimbledon] insistence that tennis players must wear only white. Some sports have rules dating back many decades, with their main focus concerning clothing being that it should provide adequate protection from injury and not risk harm to the player themselves or their opponents. For non-contact sports this may not be a factor, so comfort is a greater consideration - allowing the player freedom of movement and not distracting them by riding up or chafing at inconvenient moments when they require full unimpeded focus. Advances in sports science have meant participants in some events where speed is a primary concern better understand in the modern era how they can potentially gain crucial milli-seconds from wearing tight bodysuits which produce less wind-resistance. This applies to both genders, who will frequently add another layer of tracksuit between attempts/heats. |
Why are so many people from the Middle-East bitter towards Western civilization? | Because we've fucked them up pretty good. Many of the nations, and their boundaries were created by The West with little regard to the history of the region. The US supported at least two despots, Saddam Hussein and the Shah of Iran. Bin Laden's stated reason for the attacks of 9/11 was the presence of US troops in Saudi Arabia.Because western countries overthrew democratically elected governments in the middle east and the rest of the world on multiple occasions, and lied about supporting certain middle eastern countries independence after WWI. Instead they colonized them. It has very little to do with "different cultures".There has been unrest, hatred and wars for centuries. Think Middle Ages and the crusades. It basically stems from the holy lands for 3 of the major world religions residing in 1 area. It has been repeatedly over thrown. There have been pretty constant wars since the dawn of civilization. Think bible as a historical reference. Let's also not mention that Israel was a country created after WW2 and just taken from Palestine. |
Why was it a bad idea of America to be backed up by the Gold Coin? | One of the biggest problems with it is how inflexible it is. It removes a lot of the techniques used to combat recession and depression. It prevents running deficits, which are necessary for state-wide economies. Price stability for gold was extremely volatile, which lead to markets that were very volatile - another mark against the gold standard. Not to mention the fact that there's not enough gold in the world to cover the US's economy. |
Why is it that One World Trade Center has less floor area than even one of the two Twin Towers? | Because it's not as big? How many stories is each building? How big around? Also, there may be a distinction between physical size and usable space once you account for supports, stairwells, etc. |
Why doesn't the American Military do something to stop the Mexican Drug Cartels? | If that's a topic you're interested in, Tom Clancy's *Clear and Present Danger* is a very entertaining read about a joint Army/CIA operation against the Columbian drug cartel. |
Why is it so hard to maintain eye contact when speaking with someone? | It's good to maintain eye contact. If you aren't feeling comfortable, you might have some issues with social interactions. This isn't necessarily a bad thing, but you might find people will see you as less trustworthy if you can't maintain eye contact. Just keep at it and push yourself to make eye contact. If you stare at their mouth, they're going to notice. If you stare beyond them, they're going to notice. There is no trick that is going to trick someone into thinking you're looking them in the eyes. The only thing that you can do is to just get into a habit of it. Next time you are watching a news report or something of the likes, when the person speaking on camera stares into the camera, stare into their eyes and practice blotting everything else out. There will be less social pressure in those situations and it may soon become a habit if you just keep practicing.What happens when someone stares at you? It makes you uncomfortable. What happens when you are speaking to someone who isn't even looking at you? It appears as thought they do not care enough to acknowledge what you are saying. Humans conversing walk a fine line between appearing aggressive/confrontational and/or appearing disinterested . This is exemplified in people who are "socially inept". They often cannot balance the two, something that the average person will pick up on very quickly.In the D/deaf community you don't necessarily keep eye contacting you are an observer a performer.however, the initial locking of eyes is initiation or deferral to converse, but most people who talk look away whereas listeners observe language of the body and awareness of conversation |
What's the explanation for physically recoiling when we see something really odd or disturbing? | Possibly not the answer you're looking for, but relevant: VSauce made a video touching on things that are creepy or disturbing, and why it makes us unsettled. _URL_0_ Edit: Upon rewatching this video, I almost want to tag this NSFL, because I get creeped out every goddamn time. |
Why does Java need or get such an incredible, stupendous number of updates? | Wow, none of you have come close to the real answer. When you get that pop-up from Java, it's asking for the permissions it needs to run its installer and perform the update . Now, this is the important part: that didn't actually start the update process. You have to manually go to the icon on your taskbar and click install . So, the reason it seems like it is always asking you to update is because you haven't really updated those previous 100 times, and that's why it keeps asking you again and again and again. |
Why are some morning people and others more of a night owl? | Basically it has to do with how long your internal clock thinks a day is. Nobody's is exactly 24 hours. if your internal clock is slightly more than 24 hours you are still going late at night. If your internal clock is slightly less than 24 hours you are ready to go in the morning.I believe it has everything to do with training yourself to a certain sleep schedule. For example, a DJ who has to work nights, will sleep during the day and work at night, after a while adjusting to being a night owl due to lifestyle. A 9-5er who needs to be up at 7am every morning will be a morning person ', "I'm a night-owl but I want to change, to what degree is this possible? |
Why does our depth perception get so bad while covering one eye or wearing an eye patch? | Depth perception comes as a result of seeing something from two slightly different angles-- one from your left eye and one from your right. In essence a person sort of triangulates the position of an object to estimate how far away it is. When you see something with one eye, you can't do that, so the image appears a little bit flat.It is not possible to perceive depth with one eye, as it produces only a 2D image. With 2 eyes, you get 2 2D images, effectively 3D. This you perceive depth. I am no biology expert, but if you had 100 eyes, you would have an even better sense of depthWhat I wanna know is if you had a third eye, how would THAT change your depth perception. |
Why are eggs such a common ingredient in many baked goods? What do they do? Are there any alternatives that work just as well or better? | Baked Goods and Eggs: What Do They Do? Do They Do Things?? Let's Find Out! |
Turbo in an Engine. And the difference between Turbo, Turbo-charger and super-charger and how these differ from just a regular old combustion engine. | Your car has to suck in air, or breathe in order to run. Just like how air comes out of the exhaust, air must go in first. Boost is where air pressure is applied to the engine instead of the engine just using it's own vacuum to suck in the air. Its kind of like if you were breathing off of a tube that forced the air into your lungs. Now imagine that the life force of your energy was instantly and at all moments dependent on the air you breathe, and the more you can breathe the stronger you are. That's boost. Turbo gets it's power from the air pressure of the exhaust. Just like some pneumatic tools it uses the energy of the air pressure to spin a fan that forces more air into the intake of the motor, making it rev up faster. Super chargers use the Flywheel of the motor, just like the alternator and the A/C to turn a fan that forces more air into the intake of the motor, making it rev up faster. |
If all the cells in our body are replaced every ~month. Why do we keep things like scars and wrinkles if they're not in our DNA? | Because scars and wrinkles aren't cells. They may contain cells, but what they really are are collections of protein fibers. Skin is normally a mixed collection of fibers, collagen for strength, elastin for elasticity, and others which connect these together and to the cells. Scars are a collection of hastily laid down collagen fibers to plug a hole. Wrinkles are just a collection of typical fibers which make up the skin but in which the elastin has lost some of it's elasticity, thus gravity takes over pulling the skin out. Follow up - Why doesn't the body just make more collagen and elastin to fix scars and wrinkles? Imagine the work it would take to replace the load bearing frame of your house while still living in it. Same thing with the body. It's really hard and generally not worth it. |
Why not just Google your question to find the answer instead of posting it on here? | Because,if you're anything like me,you end up staring bleary eyed at 15 Wiki tabs at 10am with a dual grip on a mug of coffee.Because: u/imfive: [Search] What the hell is the benefit of an ionizer and why should I buy a **fan** with one. Google: So, you want to buy a **fan**? Here are 1,003,044,734 results for **fans**, starting at $1.99. .Because we trust people, more than a random block of text on wikipedia, to give us better, more understandable answers. And if we still don't understand after the explanation is given, we can ask further questions to clarify. Same reason we have teachers actually teach us lessons rather than just having all the students read a book or two to learn something.Pretty sure the answer to this question is searchable on Google[Why not just Google your question to find the answer instead of posting it on ELI5?]', "Because Google doesn't give you karma for asking. |
Why do presidential nominees in the United States get briefed on top secret national security information? | Things start happening months in advance. Its the idea of hitting the ground running. A soldier doesn't immediately go off to war. They first require training. |
Why does the moon not rotate? | It does rotate. In fact, it rotates at almost exactly the same rate as it rotates around the earth - that's why the same face always faces the earth. |
Why does Windows use file extensions everywhere (like .exe or .txt) and Linux usually doesn't need them? | > The UNIX-like filesystems use a different model without the segregated extension metadata. The dot character is just another character in the main filename, and filenames can have multiple extensions, usually representing nested transformations, such as files.tar.gz. Programs transforming or creating files may add the appropriate extension to names inferred from input file names , but programs reading files mostly ignore the information; it is foremost intended for the human user. This model generally requires the full filename to be provided in commands, where the metadata approach often allows the extension to be omitted. they don't need extensions in filename, because it's sort of coded into the file. |
How does counting cards work in blackjack? | Basically, you're not actually keeping track of every card. You're usually keeping track of when there are more high cards than lower cards as higher cards benefit the player more than the dealer. When you've seen a lot of low cards, you increase your bet to take advantage of the better odds. It's usually not worth the trouble as most casinos have optimized the rules and procedures to make the advantage fairly minimal. |
How come minors have to pay taxes in the US? Since they can't vote, shouldn't they be tax exempt regardless of their income? | Ignoring the question entirely, I can't even begin to understand why you would think that being unable to vote should/would make you exempt from paying taxes non-citizens can't vote, but they still pay taxes. Taxes are paid for upkeep of the country. |
Why do we have two separate machines for washer and dryer? Is it not possible to combine them? | It's possible, and currently being done. _URL_0_ Why did it take so long? That's the real question. |
What is the point of accumulating wealth beyond of what you can spend in a lifetime? | They're either trying to ensure their families will be taken care of for however many generations after they're gone, or hoping to establish something that will have a lasting impact. Or sometimes I guess they're just competing with the other rich people.Some of the people on the list agree that they have too much wealth and have pledged to donate at least half of the wealth by death. About 365 billion dollars have been pledged and 139 individuals or couples have pledged. |
Why do people only fill half the glass when pouring wine? | Part of drinking wine is the smell. If you fill the glass, aroma can't accumulate for you to smell as you drink. |
How is plumbing fully functional during a power outage? | I'm not a plumber, but its because it doesn't rely on electricity. Just the pressure of the water coming from a pumping station to you.Water is fed by gravity to your house from a water tower if you are on a public system. Municipalities use electric pumps to get the water up into the tower, then gravity is used to feed it to your house. Some pumps will have backup power in case of an outage. If you are on septic and well, then you either have a battery backup for the pump or you are out until the power comes on. |
When my cell phone is limited to making emergency calls only, why can't I use the signal for other things? | Your cell phone doesn't have a registered account with the phone company that owns the tower that provides the signal. That means that they are unable to send a bill anywhere for services used over that signal. They let you make emergency calls because that's just a good idea , but nothing else because they can't make you pay for it. |
Are airplanes flying as fast as they can? | Landing earlier usually results from tailwinds or routing changes, or it's a Jedi mind trick because they pad the gate-to-gate times for delays. Commercial jets can fly a bit faster but don't for reasons of fuel economy. Also, flight gets unstable as it approaches the speed of sound. |
How can a medication cause such a specific side effect as thoughts of suicide? | You can be SO depressed that you can't bring yourself to do anything, including suicide. Certain medications will lift you out of that depth to where you're still depressed, but now motivated to kill yourself. |
why do we sometimes sweat excessively when sleeping? | Sometimes if you enter a deep sleep you won't wake up to take the blankets off if you're too hot |
If mosquito's are attracted to light. Why don't they all fly to the sun and leave us alone? | this is by far the **best** thing i've ever heard on reddit! get my upvote sir", 'Insufficient delta-v. They would need mosquito boosters in order to conquer space.Isn't it the infrared light that we emit that marks us at food? |
How can turtles eat food underwater without swallowing too much water? | How can you eat something under air without swallowing too much air? It's the exact same mechanism. When you close your mouth you squeeze out the air while holding the food in with your teeth, tongue and lips.I cant say for all of them but i know the lether back turtle has a load of spiky things in its mouth that point inwards This lets it spit the water out but hold on to its foodWell duh, how do you think they wash their food down? |
how sharks can smell blood from such far distances away underwater | We don't know. Something else equally mysterious is how they seemingly can tell when another great white has been killed hundred of miles away. When it happens, all great whites in the vicinity pretty much take off for the other side of the ocean. _URL_1_ |
How are those glass decorational items made? The ones that are just a solid glass blocl, but with some kind of 3-D image inside of it? | Hmm I would have thought they were a special kind of laser: ultrafast lasers, or femtosecond lasers. They have extremely short pulses with huge amounts of peak power. Unlike 'normal' lasers that machine or mill material away by boiling and vaporising, these lasers machine or mill by 'cold ablation': the huge light field power frees the electrons, then it becomes opaque, so absorbs more light, so it frees more electrons, then it becomes more opaque etc etc. Eventually there is no more electrons holding the material together, and it just explodes. It's just that it happens in a tiny scale; if you look at it with a microscope, it's an absolute mess. |
Why are computer error messages a mixture of numbers and letters instead of an actual useful and understandable message? | the OS doesn't know why the program _URL_0_ only knows that it has crashed. And anyway even if it did know why the program crashed it would be impossible to have an error message for every possible reason that a progran crashes |
Why do dentist have the highest suicide rates? | While I would like to say it's because they're tired of telling you to floss more, it's probably more complicated than that. |
What's the difference between "Professional Photography" and something you would see on instagram? | It's like the difference between a professional chef, and a college kid making macaroni and cheese from a box. Yes, they both make food, but the similarity ends there. Or between a professional artist, and a kid doodling in his notepad. Professional photographers do use much more advanced equipment than a smartphone. However, photography is an art form. Just like Jimi Hendrix could outplay 99.9% of the world on a $80 Wal-Mart guitar, skill and talent come into play much more than the cost of the equipment. Professional photographers understand composition, lighting, exposure, and many other aspects of photography. They go in with an artistic vision, and modify their equipment and surroundings to achieve it. They are not simply taking a picture of an object. |
Why is "If man evolved from monkeys, why are there still monkeys?" not a good argument against evolution? | Say you want to do a little selective breeding. You take 2 golden retrievers that each have a specific trait you want to breed into a new animal, like unusually coloured fur or whatever. Once your dogs breed, they'll have a litter of puppies, some of which will have the differently coloured fur, but most will just be regular golden retrievers. That's why there's still monkeys. Because while a small number of monkey offspring slowly became humans, the rest of the baby monkeys didn't change, and are still monkeys. edit: grammar |
What is it about the hiring process that leaves many recent grads unemployed? | no" or "a little". THANK YOU! Was that so hard? SOOO much easier to train someone who is ready to learn and not someone who is looking for a way to make their previous experience relevant. I'm not hating on older workers in general, just this one little area. Willing to learn means admitting you don't already know. |
How does the justice system compel a defendant to participate in a civil case? If someone wants to sue, what stops the other party from just saying no | I can only speak for the U.S., but you're not compelled to participate as a defendant in a civil case any more than you are in a criminal case. You don't have to say or do anything. The case will proceed and since you haven't done anything to defend yourself, the court will find for the plaintiff. You don't have to agree to be sued any more than you have to agree to be charged with a crime. |
How do theoretical physicists find solutions to the biggest and smallest answers to the universe using math alone? | Theoretical physicists make models, not solutions to answers. In practice the models are much more complicated than my example, but the idea is very much so the same. Say you're playing a game and what to know your win rate. You know how many games you won and how many games you played. The formula for your win rate /=winrate. Now, when you look at that formula you see that you can use it to determine any 1 of those variables so long as you know the other two. You also notice that your win rate is only dependent on those 2 variables, and only those three variables. It's not dependent on the moon phase, not dependent on the time of day, or anything besides those 2 variables. In this particular example that's obvious, but in general that kind of thing is not obvious. So, just by creating an obvious formula we discovered that your win rate is only dependent on 2 things, and we were able to make predictions with that formula . |
Why can't they make a flat, rectangular map of the world without severely distorting the actual size of land masses further from the equator? | You can't project the surface on a sphere onto a flat surface without stretching. This is a result of [Gauss's Theorema Egregium] which defines a quantity or measure of curvature at each point on a surface and says that bending a surface without stretching can be done only when the measure of curvature does not change. [Here's a visualization from numberphile]. A sphere has constant positive curvature at each point on its surface and a flat surface has zero curvature. Therefore, there's no way you can bend one into the other without stretching. |
Why are we comfortable in 95 degree water, but not 95 degree air? | You shed heat faster in water. In really dry 95° F weather you can be comfy in the shade, so long as there's a little breeze. You'll perspire enough to avoid overheating.I 've got a relevant followup: Why is it that 85 degrees OUTSIDE is "a nice day" but 85 degrees INSIDE is "omfg turn on the Air Conditioner"?The body just needs to stay at a comfortable working temperature. At the temperature you are talking about the body is trying to stay cool since most of our physiology generates heat. In 95 degree water there is plenty of matter and surface area to allow for conduction of heat away from our body; the water is also not raising the temperature of our body. In 95 degree air our body is trying to cool itself but is having a hard time because air is so much poorer at conducting heat away. Anyway, I personally am not comfortable in either 35 degree water or 35 degree air, but heyAlso, 95 degree water is not "comfortable" A pool or body of water at that temperature just feels grossWas seriously confused for a minute until I figured you meant fahrenheit. 95°C water is *not* comfortable lol. |
Why do carriers care if you tether? | the same reason why Hollywood cared about VCRs or the music industry cared about cassette tapes. with tethering, you'll only need to subscribe to their service once instead of multiple times .Money. It's a "service" they can otherwise charge more for. Why would they give something away when they can charge you for the privilege? |
Why does Ron Paul seem to be doing leaps and bounds better recently? | Ron Paul is the only alternative to Romney and he's stacked his supporters in leadership positions and the race is over and Romney has won so no one apart from his supporters are bothering to turn up. He's using loopholes in the rules to get delegates despite consistently losing the popular vote. |
Hydraulic lifts. How can I (80kg) lift my car (1600 kg) by simply stepping on the pedal on my hydraulic lift? | The hydraulic fluid which drives the lift can't be compressed, so as you step down on the pedal and force the fluid down, it forces the fluid underneath the lift up. This has the effect of raising whatever is sitting on the lift. This video might help, for me it's a lot easier to understand when visualized: _URL_1_ |
"Obamacare" Point-By-Point - Part 3 | Since you've read so much of this I'm curious if you can point to any of your summary sections that you think are probably not good ideas. I think it's likely a bill this large has many downsides even for those in support of it but I haven't personally seen them, I'd love to hear what you think thus far. ", 'Just wanted to say thanks a lot for doing this. This must be really time consuming but your work is very much appreciated!', "You're putting in great work. I appreciate this.Yup. Paying 2400 more per year since this was established to "meet demands of the Affordable Care Act". I make 25k/yr. In addition to all the other things I'm for some reason required to pay, I'm making 55-60% of my gross income. Yay for change.And you are doing this for internet points? :) Kidding. Thank you for taking the time to do this. I don't think anyone literally anyone, anywhere, has done something like this. So again, thank you. |
why are the European branches of American companies usually run from Northern Ireland? | There are several reasons: 1) As mentioned by other users there are many tax loopholes that companies can take advantage of and save billions. 2) Ireland has a lot of people who speak English as a first language and so they can communicate fairly well with people in North America 3) Ireland is one of the countries at the forefront of Europe's technological boom and has a lot of advanced infrastructure and capital that companies can take advantage of. 4) This kind of relates to number four, the people of Ireland are on average more competent and familiar than most with using newer technology. 5) Ireland is one of the closet European countries to North America. 6) And I'm surprised no one mentioned this one: conveniently Ireland is about 8 hours ahead of places like L.A. So if branches from America and Ireland were working together on a project then the L.A branch could do their part send it to the Irish branch then go to sleep and wake up to the Irish branch done their part and vice versa.Aside from tax issues privacy laws are a big part of this. Since Ireland is part of the EU companies based there can avoid the stricter privacy laws that exist for example in germany.Amazon pay less taxes than me being based in Northern Ireland for example Needless to say we don't have the same income |
How was Beethoven able to write all that music without hearing it? | Early in Beethoven's career he apparently had normal, healthy hearing. And during this time he developed his skill with perfect pitch. What this means was that he could hear a note being played and identify the key, and whether or not it was being played sharp or flat. And it also means that he could *accurately* imagine a *specific* note in his mind, which made it possible for him to compose music *as if he was actually hearing it* regardless of how bad his deafness became. Supposedly he used the feeling of vibration to help this approach as well, but a lot of those accounts seem like urban legends to me.He started to go deaf gradually in his thirties. He was totally deaf only the last decade of his life. By that time he had enough experience to write down music directly from his head. He did give up performing and conducting though. |
How is it possible that no two people have the same fingerprint? And who discovered this and how did they do this? | It hasn't been discovered. We don't *know* that no two people have the same fingerprint, we're just kinda assuming that it's true. |
Why is wifi free in cheap hotels, but paid in expensive ones? | Couple of things: If you can afford to stay at the expensive hotel, you're probably not going to balk at a $10 wifi charge. Also, the expensive hotels are often more focused on business travelers, who need the internet to work, so they don't have a choice. Also, they don't care if it costs $10, because they're getting reimbursed on it anyway. |
Why it is so common for people to misunderstand freedom of speech? | Because most people don't understand the Constitution at all. If you stop the average US citizen on the street and ask them the purpose of the Constitution, most people will tell you that it is the document that grants us our rights. This is the exact opposite of what the Constitution actually does. The founding principles of the US–from which the Constitution derives–are very clear that no document or institution may grant rights to people; all people are born with all of their natural rights. What the Constitution can do is strategically *infringe* our natural-born rights in order to grant certain rights and powers to government. The Bill of Rights, including the freedom of speech, is about drawing a bright line around some of your natural born rights to make absolutely clear they cannot be trespassed upon in all this strategic infringement of rights-granting to government. So this is the fundamental misunderstanding. People who misunderstand the origin of their rights feel that if they are given rights by the government, those rights ought to have force everywhere regardless of the context. In fact this is completely wrong; the Constitution is about enumerating the powers granted to government, and therefore the Bill of Rights is about limiting those governmental powers when applied to citizens. In short, the freedoms protected by the Bill of Rights protect those rights in the context of powers granted to government only. All of these protections have to do with government exercising these powers when prosecuting crimes. This has nothing to do with how private entities' rights interact when dealing with each other that's a matter for civil law.There is a difference between freedom of speech itself and the actual laws that uphold it. Being banned out of pub *is* restriction of their freedom of speech, but a legal one. People assume the law grants them absolute freedom of speech, which is not the case, but actually reading laws is such a bore. In fact, people tend to have most bizarre ideas about the laws of the countries they live in and their own rights. |
Submariners, from the point of view of the crew aboard. Once submerged, do subs ever experience "rough seas"? | Not a submariner but an aircraft carrier doesn't experience many weather effects either. When dodging a hurricane, we only had 5 degree rolls. |
Why do I have hair in my ass crack? | I think it has to do with keeping bugs and dust and shit out of your body's holes. Same reason we have eyelashes, nose/ear hair, and pubic hair. Bugs and other things find it harder to find their way through a thick forest of hair. Pubic lice must have evolved to exploit this however, but on the evolutionary scale, shit happens i guess. |
What takes more energy, to maintain the house at a temperature while I'm gone for a few hours or to turn off the ac and turn it back on when I come back? | Your AC uses less energy when it's off than when it's on. Period. However, comfort may dictate that you don't turn it completely off when you're gone. Your AC may not have the capacity to quickly return a very hot home to comfortable conditions, especially when it's very hot outside. In fact it may take hours of continuous running. Hence, the programmable thermostat. It allows you to modify your setpoint while you're away. During cooling season my thermostat is set to 76 degrees when I'm home and 83 when I'm gone. For heating 68/58. It's a compromise between energy use and comfort. Source: I work in the HVAC field and specialize in controls and building automation. Edit: you're > . <", 'My Nest thermostat only being on for an hour a day says it's more efficient to turn it off than leave it on. It sees me come home at 5pm every day and I spend all of 15 minutes mildly "uncomfortable" while the house cools. |
What does the court's recent decision regarding net neutrality actually mean? | I'm completely pro-net neutrality, but since the lines really are owned by those particular companies, isn't it their right to do what they want with them? Isn't it essentially the government taking over their infrastructure? I mean, I suppose other utilities like gas and electric also own the infrastructure but have regulations so maybe I'm just thinking too much into it. |
Why are some appliances made to work on only one voltage, while others work on any voltage? Why not make all appliances work on all voltages? | The things that run on any voltage have a switching power supply to make low voltage DC to power their circuits. Things like a toaster can't work that way, making heat from electric current requires larger power levels than can be handled economically that way. Thus things with powerful motors or heating elements need to be voltage specific. |
The idea of “mental competence” in or in avoidance of court cases. | > How is it determined whether someone is mentally capable of standing trial in court The judge will make that determination after hearing legal arguments made by attorneys for both prosecution and defense, supported by the opinions of psychiatric experts who have evaluated the defendant. > what is the underlying idea behind stopping/altering a case for those reasons? That it is fundamentally unfair to convict someone of a crime who is so mentally out of it that he cannot understand the nature of the proceedings or assist in his own defense. > Also what happens to a case where the defendant has been found to be incapable of standing trial? Most of the time, the defendant will remain in custody at a government mental health facility until such time as he is determined to be fit to stand trial. It's entirely possible for such a defendant to remain in custody for longer than the maximum legal sentence for the crimes with which he has been charged. |
How does the second Ammendment protect against tyranny? Wouldn't want civil war or uprising devastate the country beyond repair? | Fear. You just answered the question. It's the same reason we don't use nuclear weapons.Plus, it's another check and balance on the government. The government can't just do whatever they want. If they become tyrannical, the common man can defend himself. |
Why do fighter jets refuel other fighter jets instead of using a tanker or bringing another external fuel tank? | It's known as a buddy store and allows carrier based fighters to extend their range while carrying more munitions. _URL_0_ |
If I came from a planet with much higher gravity than Earth and came to Earth, would I be stronger and faster than everyone, also, what would the drawbacks be? | I would think that if you grew up on a higher gravity planet, you would be shorter than other humans, your bones would be denser, and your legs would probably be a lot stronger. You'd look like a dwarf, really But you would be stronger than the average human. Now, if you were a creature from that planet and weren't just a human that was raised there and you came to earth , then you would probably be like a super human.Yes, larger gravity makes long levers and bipedal movement more tricky. Expect to have at least 6 shorter legs. So far most earth-like planets we found are at least 1,5x as massive as earth and have a slightly higher surface gravity. Not too proportional, with much larger mass you only get a little bit more gravity. Expect an atmosphere to be much denser at surface levels, making flight easier and allowing for larger insects. Life would get smaller and wider, more millipedesYes, you would be stronger and faster than anyone here. The drawback would be your body will start to modify itself according to the new gravity and would lead to change in your current bone density and blood flow. |
Why is tooth pain so unbearable compared to other areas? | Sensitivity is why. Let somebody touch your finger. No problem. Now let them touch your toes, whoa, very sensitive and ticklesh right? Our hands are exposed. We bump them into things all the time and our minds are used to sensations from those nerves. But our feet are inside shoes and socks most of the time, and especially the tops of our toes and between them, we aren't used to them touching anything but each other so we don't have quite the same mental filters on sensations from our feet, which is why stubbing your toe hurts so much compared to stubbing a finger. The nerves in your teeth are in something better than a shoe, they are in a hard protected environment at a nearly constant temperature so most of the time the nerve sends no information we are aware of. So our brains aren't used to sensations from them and any sensation, no matter how slight, is readily felt. Hence ice cream making your tooth hurt when you eat it, or hot coffee doing the same sometimes. So when you have a cavity or abscess or your tooth cracks, or your filling isn't perfectly stable, the nerve is hyper sensitive to the pressure, heat, and cold this causes. |
Why are fruits and vegetables considered healthier than multivitamins? | It has to do with a lot more than only the vitamin counts, you have to factor in the lack of bad things. You could get plenty satisfaction by eating an apple, with a very low intake of bad cholesterol and fat, while also getting vitamins and other important nutrients. So yeah, getting a full stomach on food with low quantities of bad things, while having a variety of good properties, can be considered super healthy. If you try and get all your vitamins and gootdstuff from a pill only, you gonna be left with the option to eat stuff that has a higher quantity of bad stuff, and that's where the not healthy part comes from. You can hardly say that a fried broccoli is healthy, as where you can say a raw one is. |
Why does food stick so strongly to plates or frying pans after its sat out a few hours compared to when it's fresh? | Unfortunately I don't have an answer to what causes this, but a pro-tip I can give you is to let your dishes soak if you aren't going to wash them right away.Heat has a lot to do with it in my experience. Wash something with very hot water compared to cold. |
Why do the tips of our fingers and toes need a covering such as our nails? | Claws are used for traction and as weapons. Nail plates such as ours evolved as social grooming became increasingly important. It's much easier to grab a parasite with nail plates than it is with claws. |
How did ancient people know when the summer and winter solstices were, and why was it important to them? | In ancient times as well as today, understanding the cycle of the seasons was a matter of life or death. Agriculture was in it's infancy and mis-judging the right time to plant seeds or harvest your crop would be the difference between your family living another season or dying of starvation. The sun told you what part of the river the fish would be spawning in. It told you when to expect the mating season for the deer you ate. It told you when you hike that 30 miles that the berry bushes will be ripe by the time you get there. EVERYTHING that involved food relied on knowledge of the seasons. That's why it was so important to them. Many cultures associated the heavenly bodies such as the sun as living deities. The solstices were an obvious and natural point to celebrate and give thanks. Identifying the solstice or equinox really isn't that hard to do. You may not care about or even notice them today and you don't need to. We have farming experts that do that for us. But if you lived in an ancient agrarian society you would have paid attention to the cycle of the sun, or be dead. |
why breathing out doesn’t work when we’re choking ? | You can if you have enough air in your lungs to push it out with enough force. But chances are when you are choking, you won't have that kind of luxury. |
How Al Sharpton owes over 3 million in taxes, but is on public tv all the time. | My understanding is not deep, but legally speaking, Al Sharpton doesn't necessarily owe the taxes, but his 'business' or 'organization' does. If I'm remembering correctly, the pattern is that an organization 'goes out of business', and a new organization might be formed later on. It may or may not be shady dealings, and if there is a pattern of unpaid taxes for several organizations relating to Sharpton, that might be a problem. |
"Second cousin twice removed" | I'm a Viriginian with a complex family tree -- nothing disreputable, but one set of great-grandparents had two children shortly after marriage, then a second set of two children 15 years later, effectively dropping the second set into a new generation. Suddenly the children of the first set were about the same age as the second set themselves. This created waves throughout the generations such that two 15-year olds sitting at the same table in 1985 would have to figure out if they were once removed or twice removed. I decided that at age 8 or so, I wouldn't fight my mind's natural inclination to ignore such titles as they were stupid. That decsision has served me well. |
Why is it LEGALLY ok for nightclubs to charge male patrons more than women (free admission for women, ladies night drink specials)? | It may or may not be legal. But this kind of pratice rests in a gray area of law. So what happens is that someone challanges the law, takes a nightclub to cort and the courts decide. In almost all cases the courts decide that it's unfair. but because the prize is so small, there is very rarely any kind of settlement for this kind of case. Since the issue has never made it higher than the state courts it's legal status vary state by state. In states where there has been a challenge and they won, then it's illimitable. But not all states have been challenged, because there's no money in it. |
Is it society or genetics that makes humans view other human lives as more important than an animals? | Genetics. Every social mammal engages in some form of kin selection. It's a fundamental principle of evolution. All animals judge how important helping someone is based on how closely related they are. For example squirrels only give alarm calls to squirrels that are related to them. Preferring your species over another is a simple extension of that. The principle is known as Hamilton's Rule after WD Hamilton.RB > CA genetically encoded behavior is evolutionary favorable if the benefit to the receiver times the relatedness is greater than the cost to the actor. _URL_0_ |
Why do people claim that Fluoride is harmful? | Because it is harmful, just not in the quantities we are exposed to - people really like to exaggerate. A lot of substances are harmful/toxic in large quantities but we use products containing those substances all the time because the amount we get from those products is not anywhere near the unsafe levels. Unless you eat your fluoride toothpaste on purpose you won't reach unsafe levels of fluoride. In small quantities it is found in water and toothpaste it is good for your dental health.Because it accumulates significantly in the pineal gland and elsewhere in the body in order to get the job done. Fluoride is meant to "saturate" your body so that it ends up in your saliva. People always argue the amount is so small it does nothing etc but the fact is it does get stored unnecessarily and there are some very decent reasons to believe it could cause issues later in life. I can link studies if you want. edit: forgot mb. see /r/fuckfluoride you can find some there', "I don't like the government mass medicating an entire population on the pretext a percentage can't maintain a personal hygeine program. The fluoride added to my water supply comes from a by-product of the fertilizer process. It is a toxic substance that cost the industry a lot of money to dispose of before they had the great idea to just dispense it in the populations water supply.fluoride can be harmful if you consumed in large concentrations. That said the amount of fluoride that is put into our water supply is well below what our body can properly filter outEverything is a poison what matters is the dose. People have died from drinking too much water. |
Why in biological context is it typically more difficult for women to reach orgasm? | It's been said that the female orgasm is not necessary for reproduction. This is somewhat true, but childbirth is far more difficult for humans than other mammals. Women really need that incentive to have sex or we'd die out because childbirth is so painful. Also, it's a pretty common thing for female social animals to try having sex with as many males as possible. This both maximizes the potential for insemination, and minimizes the risk of a male killing a child for not being his. Women need to have better longevity in bed in order to mate with all the males, as opposed to the males who are totally fine cumming once and taking a nap.Evolutionary speaking men must reach orgasm to release their sperm, so it being pleasurable helps to drive them to mate. There is almost no evolutionary purpose behind the female orgasm. The only possibility as to why women orgasm at all is that sex being pleasurable means you will be slightly more likely to want sex, thus being slightly more likely to have sex, thus being more likely to have children. |
The controversey surrounding the Netflix Documentary Making A Murderer. | A bad crime happened. Steve was sent to prison. 18 years later the police found that he didn't do it. He was released. A few years after that there was another bad crime. Steven was sent to prison again for it, this time forever. Some people say that the police didn't have enough evidence for sending him to prison for the second time. |
Why don't more people in the US hold the same opinion as Morgan Freeman that the best way to end Racism is to stop talking about it? | Do you really think that's all it takes? Or are you saying most Americans already reduce their positions to a catchy slogan, so why not this one too? |
Why do some birds hop and others walk? | Smaller birds tend to be hoppers, while larger birds tend to be walkers. In short, it takes less energy to hop when you're small, then it is to be bipedal when you are big. And there are reasons gravity affects you differently when you are smaller, instead of if you were the same shape but bigger. Imagine that bug you dropped a few feet from the ground, but seemed to be just fine. If it were the size of an elephant and dropped off a large, but ratio-equivalent-story building, it wouldn't survive quite as well. So, whether a bird prefers to hop or walk is largely dependent on it's relative weight class, and why sometimes it's the smaller birds that prefer to hop, while the larger ones prefer to run. |
Why do my tear ducts leak every morning when I wake up? | This is a good question. I think it's because I'm allergic to the cat, but it might be my existentialist crisis as I wake and wonder if I have become a large insect.Because you have to face the horror of another fucking dayIts because your eyes use tears to seal up. When you wake up, your eyes are still making lots of tears, hence the watery eyes. |
Why is killing fish not recognized as animal cruelty? | fish are not warm fuzzy animals. The general public doesn't outcry for animals that are not universally considered cute. If it is warm blooded and has fluffiness people care. Scales, shells, slime? There isn't enough people that see value in these animals to move politicians to action and classify these animals under the same laws of cruelty", '"We should be concerned about the wellbeing of conscious creatures to the degree that they are conscious". -Sam Harris If you think about things in this way, it kinda works out - we should care more about killing dolphins and dogs than spiders and snakes, but should still care about snakes and deer more than we can about ants and wasps. Intention is also important: Senseless killing is a more immoral act than killing to satisfy the need for hunger, shelter, and other physical needs. Hunting purely for sport, since it is not at all for survival, could be worse than killing an entire nest of ants, despite the numbers for the ant nest being around the thousands and thousands markBecause we eat the fish. Then when we die our bodies become the tetra flakes which feed the fishPhoebe: "turkeys are intelligent, beautiful animals" Joey: "no they're not, they're ugly, and stupid, and delicious!"In general, society doesn't consider it inherently cruel to kill a "food" animal for food and focuses instead on minimizing the suffering that the animal experiences. Many of the ways we prepare foods are based tradition rather than modern science. |
What do computer components do? | Excellent ELI5, just one note: > Faster more expensive CPUs will result in faster executing programs. Not necessarily. CPU performance is measured by execution time, NOT speed. It's a common misconception that I see all too often. Your super fast but poorly optimized CPU will be no better than a slow CPU that is highly optimized. Source: 3rd year CS student. |
Origin of "$X.99" - where did this convention come from? | The first known instance of setting prices at $X.99 was in 1876 in Chicago. Melville E. Stone produced a newspaper that cost a single penny to compete with the standard nickel newspapers of the day, but most people didn't carry pennies around, so business wasn't good. Prices for goods were typically sold in whole dollar amounts at the time, but Melville convinced local shop owners to drop the prices of some of their goods by a single penny, to $X.99, which would force change to be made and put more pennies in more peoples pockets, so they'd be more likely to buy his penny newspaper. It's unclear whether this is the root cause of $X.99 becoming ubiquitous in America, but it's the first recorded instance. Source: _URL_0_ |
Why are most songs about three to five minutes long, and movies about two hours long? | Movies are mainly because that's just a good length to tell a story and not have your audience get bored. Movies used to be about an hour shorter, they were hovering around one hour for a long long time. However when we had better projection technologies we started making longer movies that required an intermission. Over time when we went from projection of film reels to mainly digital we stopped requiring an intermission for movies longer than 2.45 hours. Movies are now creeping up to be longer because we don't need to take breaks anymore and also because of digital cinema packages getting to be smaller size and higher res. Source: I'm a film student, this is just off the cuff", 'When record players were widely used, the ideal running time of a song was around 3 to 5 minutes, enough to fit in a record and enough for quick bite sized moments of music. Movies were kind of like plays when they were first coming around, so in order to tell that story it had to be longer. |
Why can't we hold our breath to death? | Because you'll go unconscious before dying. When you go unconscious the muscles that you use to choke yourself loosen up and breathing resumes as normal. |
Why don't casinos shuffle the deck frequently during Blackjack to avoid card counting? | Casinos are all about giving you the illusion that you can beat them. A player that doesn't count cards doesn't realize exactly how shuffling more often will hurt them but they know that it makes it harder for them to win so they won't play, and then the casino won't make money. If a casino paid out 30-1 instead of 35-1 on roulette they would have a better expected value, but they would make less money because people wouldn't play because they would realize that they won't win.Modern casinos have a machine called Shuffle Master. It constantly shuffles all decks inside making it impossible to count cards no matter what strategy you use. So to answer your question, Shuffle Master is a great counter-measure for card counters.Source: i work at casino. |
Why is the new nuclear fusion success of Germany important? | The nuclear power plants of today basically take radioactive rods which get very hot by themselves and we throw lots of water at them to make steam and then we use that steam to turn big turbines. Then later you have the nuclear waste to deal with and there is limit amounts of nuclear material and there's obviously lots of risk with nuclear power plants, chernobyl fukushima 3 mile island. With nuclear fusion. You basically take a tiny amount of hydrogen and are converting it to helium. Get it fusing but the amount of energy released means it's going to be very very hot. Which is the problem. However if we can manage the heat and maintain the reaction. Then we will be able to do the same. Use the heat to create electrcity. The big deal is that in a 'meltdown' there's no chernobyl that's going to happen because hydrogen and helium isnt a radioactive disaster.There's also no nuclear waste. |
Why is it so cheap to buy items in America vs other areas of the world | 1. US produces everything. I mean everything. Meat, produce, diary, beer, wine, cars, clothing, electronics, you name it. This includes stuff made in other countries. Those clothes made in China? Well, you can't buy them in China. They are for export only. iPhone is made in China? You pay import tax if you buy it there.2. US has a huge buying power. We, or I should say they because I'm just a Canadian living here, buy a lot of shit.3. Cost is low. Immigrants, both legal and illegal, brought down the labor cost. Gas is cheap because US has the best refineries. US imports crude but export refined products. Saudi has all the crude. But it's worth nothing if you can't refine them. Then there is domestic shipping cost. US has the most advanced freight train system in the world. Other countries can shame US on passenger trains. But when it comes to ship large volume cheaply across the country, US is number one. These are the important ones I can think of. Other comments also mentioned the vast land mass and lower taxes which I totally agree. |
Why is it legal for a cop to lie to you, but it's illegal to lie to a cop? | Same reason why they can speed, look on their phones while driving and be on their computers while driving. Because they're better than all of us. |
You get arrested and taken to the police station. You say "I want to talk to my lawyer." How exactly does this work? | Usually officers will simply quit questioning you. If they have charges you will be arrested and taken to jail. If not, and not enough evidence is present, you will be released. Public defenders just don't show up and usually cops don't have time to wait on lawyers if one is contacted so the conversation is abruptly stopped by such a request. There is a difference between stating you want representation and simply stating you don't wish to speak. If you ask for representation officers should cease questioning and any questioning done after that point will not be permitted to be used against you. If you simply say you don't want to talk, officers are permitted to continue and try to get you to talk. |
How smarter is a person with a 160-170 IQ than the average person? | Every test is different and the IQ value itself doesn't mean much, the only figure that matters is how many standard deviations or percentile it measures. For example, to qualify for MENSA , you must score at least the 98th percentile on one of two tests. One of them is a fairly standard IQ test, with a score of 140 placing you well into the 99th percentile, or among the smartest 1% of the population. 160 or 170 could mean different things depending on the specific test administered, but it would likely put an individual between the 99th and 99.9th percentile, meaning that they're definitely in the top 1%, maybe not the top 0.1%. Not sure a 5 year old would grasp all that but hopefully that helps answer your question. Edit: Being smart doesn't mean you don't have to work! I'm currently a math major at uni, and even though I tested 99th percentile on an IQ test I'm struggling to keep decent grades even with lots of studying. College is hard, STEM majors are hard, and there are loads of people here who are way smarter than I am who still struggle. |
If sea mammals breathe air normally, why does getting stuck on land result in a swift death? | I've read many of the great posts in this thread; that made me curious: if getting on land crushes, dehydrates and sunburns sea animals, how did they manage the general crossing from oceans to land millions of years ago?", 'A lot of mammals require their skin to be wet so when outside of the water they can die of dehydration', "the weight of their own bodies their skin is usually almost always in contact with water, so it isn't protected against the sun there's more to living than just breathing", 'Overheating, the body not being supported by the water and dehydration would all take a toll. |

Why aren't personal finance classes required courses? | It IS required at some schools. I had to take one to graduate High School . At places it isn't, it's because the state board of education sets most of the required classes, and after a certain point they get worried about adding too much to the required list and looking like they don't care about the basics, like Math and English, so Personal Finance gets cut. |
