How do digital clocks fall ahead or behind the actual time? | Your phone is typically continually updating its time after being sent the info from a tower, the tower itself having, or having access to, a clock that has better precision. A lot of vehicle clocks or whatever are just kinda tossed together with good enough parts and a good-enough crystal to do the job, but they aren'... |
How are images transmitted in tv? | It's a series of tubes. Cable is produced through coaxial cables that use electrical signals to send a message that is the translated by your television to make a picture and sound that is acceptable to human perception. Antenna use radio waves to send a similar yet more limited signal through radio waves that does the... |
How does ear candling work to clean ears? | It doesn't work. Ear candling is pseudomedicine, it is completely ineffective. It can even be dangerous, as molten vax dripping from the candle can harm the eardrum or block the outer ear. |
Why is it easier to keep a bike stable the faster you go? | Conservation of angular momentum of the wheels. A spinning wheel does not like to be tilted, as angular momentum has to be conserved. The faster it is spinning, the more angular momentum it has. To fall over, it would have to transfer all that angular momentum to the surroundings. [Here's] a demon on the physics. |
Before digital cameras, did pictures have a resolution? If not, how was image quality measured? | Sharpness in images from traditional film cameras is based entirely on lens quality, film sensitivity, enlarger quality and paper quality. The image itself was entirely analogue, there was no way of measuring 'quality' objectively. There is no 'Megapixel Equivalent' measurement for film images, despite what people gues... |
Why cell phone companies don’t implement some kind of public key authentication to track robocalls? | Because almost no robocalls come from cell phones. Robocalls come from companies who have a more direct connection to the telephone network, either through a voip carrier or by having a direct digital circuit . & #x200B; There's really two types of robocalls: & #x200B; 1) Marketing calls. In general, as annoying as the... |
Why do people get discounts on large items by paying cash? | There are transaction fees associated with credit card transactions, generally in the 2-2.5% range. If I'm buying a $10,000 item, the person selling it to me would get $9800 and the credit card company would get $200. It's also possible something shady's going on, and they're wanting cash payment to avoid there being a... |
How does witness protection work for celebrities and face tattoos? | Presumably he'd get the tattoo removed the best he could and potentially wear makeup to cover up the rest. I'd be willing to bet that if you saw him walking down the street with a different hairstyle and no tattoos that you wouldn't recognize him. |
How does Intermittent Fasting (IF) work as opposed to eating multiple smaller meals a day? | Yep. Weight loss is purely calories in calories out. With discipline being the deciding factor of whether or not you are successful. Try to maximize food weight to calorie ratio. This usually means cutting out bread. You can do CICO with bread, you'd just be pretty hangry as a little bread=a lot of calories. I find it ... |
How come all kinds of different animals enjoy pets and scratches? | Most animals can feel itching. It's a sensory-based defense against parasites. Scratching to rid themselves of parasites, and is something of a pleasurable feeling. Plus, their muscles can ache just like ours, meaning that being rubbed can feel good on a deeper level. |
Why doesn’t wind chill effect the thermometer? | Because your body doesn't detect temperatures, only the the rate that the body is gaining/losing heat. Wind chill increases heat transfer rates, which makes it feel colder than that temperature normally would on a calm day. Thermometers don't measure heat transfer rates, only the absolute temperature. |
How do credit cards physically work? How is data stored and taken from it via chip/strip? | It's actually very simple. The chip or strip just contains a single id number. The register takes that number and a bill of sorts of given to the credit card company explaining who bought what. The credit card company takes this information and figures out what you owe. You know how when you buy things online, you only... |
When is CO produced when using a gas oven and/or burners? Is it a risk for apartment tenants? | CO is only produced when there's not enough oxygen to burn the fuel. Assuming your oven works properly there is negligible CO produced. & #x200B; However, there is always a very small amount of CO produced when you burn anything. Normally this isn't a problem, but if you're using your oven to heat your apartment, you'r... |
why do american fuel pumps have one nozzle for multiple fuel selections? surely they'd all mix | They do mix a little bit. Whatever octane was pumped previously will be filling part of the hose when you go to purchase your own fuel. So, if the person before you bought 88 octane and you buy 93 octane you are going to get maybe half a liter of 88 octane before you start getting the 93 octane you paid for. The price ... |
Why does spicy food hurt my belly | Plant: develops toxin to prevent being eaten Human: cultivates plant and selectively breeds plant to have stronger toxin because it wasn't spicy enough Plant: confusedpikachu.jpg |
How does a breathalyzer detect blood alcohol content by blowing into them? | Your blood leaks alcohol into your lungs, which evaporates as you breathe. The rate at which it does this depends on how drunk you are. The breathalyzer can measure the alcohol vapor concentration in air and determine a rough estimate for your BAC. Interestingly, you can also get drunk by inhaling ethanol vapors while ... |
What makes my head hurt during a headache? | I get really bad migraines to the point where I've gotten bilateral occipital nerve blocks and botox to no avail. A few days ago I got aimovig, hopefully it helps : that can feel the pain stimuliAlot of different factors can create a headache! From dehydration, trauma to the skull, or simply tight neck muscles!', "New ... |
Why do two negatives multiply to a positive? | Multiplication is basically glorified addition If you're multiplying two numbers youre basically adding.2x3 = 0+2+2+2 = 6With negatives, you subtract2x-3 = 0-2-2-2 = - 6Double negatives subtract by negatives which means addition-2x-3= 0--- = 0+2+2+2 =6 |
Why are golf balls shaped the way they are and not perfect spheres? | Counterintuitively, it's to improve aerodynamics. The reason for this is that there are different effects contributing to the drag on the ball. [Here is a photo of a ball in a wind tunnel], using smoke trails to show the airflow. You can see that the air flows smoothly around the ball's surface at first, but as it pass... |
Why toddlers are so great in learning languages ? | Between birth and 5 a child's brain goes through the biggest period of growth. Its creating synapses and learning at outstanding rates. This is why up until the age of 5 it is considered the most critical time to teach children. Children will also pick up so many cues from their environment during this time. |
Why does it take so long for mood stabilizing drugs such as antidepressants to work? | A few reasons. Medicines for mood generally work by increasing some of the chemicals your brain uses to talk to itself. This starts right away, but it can take a while for the levels to get to normal numbers. Also, when you have the wrong levels of chemicals, you start thinking thoughts that aren't true, and they hurt ... |
Why does a scientific calculator show "0" as a result if I add 1 to a really high number and then substract said high number although it should show "1"? | Your calculator doesn't store all of the digits for 2^50, so the 1 at the very end gets removed from the memory. How many digits a calculator actually holds depends from calculator to calculator. |
How do spacecrafts not melt off through launch if the temperature in the exosphere is 1700 degrees celsius? | What everyone else said about heat transfer in extremely rarefied atmosphere is correct, but the bigger issue is why argue with a flat earther? There's literally no facts, evidence, proof, etc. that would change his or her mind. On the other hand, I'd ask how they know the exosphere is 1,700 degrees C. I assume it's fr... |
How do you feed people with brain dead coma? | A feeding tube or intravenous injection, depending on whether the stomach, liver, etc are functioning. Because a lot of bodily functions can operate on autopilot, it's not hard to keep a functional body alive with minimal brain function. It's just a matter of keeping airways clear and nutrients flowing. If the stomach ... |
How did corporate raiders boost share prices? | Other answers are better than mine, and it was touched on, but I want to let an important point be known. This practice is not only not gone, it is commonplace. Most attempts are thwarted by majority shareholders, which is why it's been quiet recently. Takeovers take a long time to pull off. |
What is political polarization? | Worth noting that the Democrats being a liberal party is not actually on the left. They are just to the left of the Republicans. The idea of polerazation is that parties are unable to work on common goals to focus on things that are of interest only to one side or the other. Not necessarily good or bad. But in America ... |
Why are launches by SpaceX or other space agencies ever scheduled for night? | Weather is important, but it's not the primary concern when planning a launch. The most important thing is launching inside the launch window. A spacecraft has as certain window to launch where it's possible range of trajectories will place it in the correct orbit. For example, for spacecraft going to the ISS, they hav... |
How are machines used for medical imaging calibrated? | Medical physicists run a gamut of testing and calibration on xray, CT, and MRI machines. It's really fascinating stuff. At least for xray and CT they measure the radiation dose levels , accuracy of technical factors for the xray tubes , and a whole bunch of other things. There are also biomedical technicians who have l... |
If light sets the cosmic speed limit, how did the universe expand trillions of kilometers in every direction in only fractions of a second during the big bang? | Light doesn't set the cosmic speed limit. The cosmic speed limit, is just the speed massless particles and information moves in space. So since space doesn't transmit any information, it can expand faster than light relative to any point. |
Why do people pretend to hate puns? | Sometimes its just annoying when you're talking to someone and the only thing they do is try to make puns based on your words or sentence structure instead of actually listening to you. That being said I think puns are funny at time but can get quite annoying when its the same person saying them over and over again in ... |
Could I see the stars from the suns surface? Why or why not? | Some people who spend their lives in a big city have never actually seen the stars. This is because of light pollution: all the lights surrounding them on the ground effectively 'drown out' the very faint light of the stars that reaches the Earth's surface, even in the middle of the night. This is also why it's a lot e... |
Why are banknotes used for large denominations of money, and coins for smaller amounts? | I'd say it's because larger amounts of money would be troublesome to carry if it were coins. For example; it really only takes a few coins to cover everything up to the first paper bill. But then you have an infinitely high amount of money you could have. And being banknotes would make it more manageable. There's a lim... |
How do inch fractions work? | All very valid answers and I'm getting the idea. Do you find it time consuming to measure in fractions though? I'm not trying to discredit the Imperial system or saying Metric is superior in any way. |
why is skin dryer after being wet and drying? | Also the salt content on your skin results in salt water drawing water out of your skin to equal out the salt concentration across your skin. A hypertonic solution is formed and attempts to meet equilibrium across a membrane. This is similar to the reason you get all pruney when you're in water for a long time. |
why is chicken noodle soup good for you when you are sick? | Lots of protein, micronutrients, it's cooked so it's easy to digest, broth is good for keeping hydrated, salt and pepper are good for combating symptoms. |
If nicotine increases the flow of adrenaline why does it feel relaxing? | Because your on edge from not having nicotine. The true thing your addicted to. & #x200B; So the reality is cigarettes don't calm you down at all. If you weren't addicted to them in the first place you would be fine. |
Why do companies like Coke, McDonalds, and Walmart still spend money on big ads? People will buy there stuff anyways because they're so big so why? | Because their competitors will spend tons of money to out-expose them. It's like an arms race that never ends. If Coke stops showing ads, Pepsi will continue to show ads and eventually gain brand recognition over Coke. Same with Budweiser and Miller, Toyota and Honda, Walmart and Target, etc.Coke and Pepsi are the easi... |
why doesnt black absorb all light? | The color that we see something is a reflection of what is being absorbed. Something is black colored *because* it absorbs all the light; it doesn't absorb all the light because it is black, if that makes sense. Something that appears grey is just absorbing most of the light uniformly , and reflecting some of it at les... |
Why is thunder significantly more frequent during summer than during winter? Also, why are there often thunderstorms in the evening of very hot days? | If you live in Lake Effect Snow country like Western New York, there's plenty of what's called Thundersnow. The difference in air temperatures between the warmer waters of the lake and the cold arctic air blowing in creates a powerful convective engine that pulls a lot of moisture out of the lake waters into the cold a... |
Why does rain come down in droplets and not a steady stream? | Rain happens when the water in the cloud gets too heavy to stay suspended in the air. Each raindrop usually forms around a small particle of dust that accumulates moisture until it's heavy enough to fall to the ground. |
How do astronomers calculate distance through redshift? | It works on the assumption that the entire universe is expanding evenly. This means that the further an object is from you, the faster it's moving away. And proportionally so. All you need to do is look at the spectrum of light coming from a distant object, determine how far the colors are shifted towards the red, and ... |
What exactly is Pavlovian Conditioning? | A few extra things to note -despite the popular belief pavlov never used a bell. Instead the sound machines made prior to releasing food for dogs was the stimulus which caused salivating. Pavlov was a physiologist who was initially focused on dogs biology -pavlovian conditioning or classical conditioning is less import... |
why a fractal has an infinite perimeter | In general, an N+1 dimensional enclosure can contain an infinite amount of N-dimensional measure. In simpler terms? You can enclose an infinite perimeter in a finite area , or an infinite area in a finite volume. Suppose you had a huge sheet of perfectly thin paper, a sheet with an arbitrarily large amount of area but ... |
Why is there an explosion anytime an atom is split apart? | There isn't. An atomic bomb isn't the result of a single atom splitting but rather many, many atoms splitting. And it isn't any kind of atom; large atoms splitting release energy and small atoms fusing together release energy. The crossover point is around iron where neither fusion or fission release energy. |
why do car radios and infotainment systems turn off for a few seconds when starting the engine? | When an electric motor starts, it uses a whole lot of current. If you've ever noticed lights dimming when you turn on a vacuum cleaner, the same thing happens when you start your car, which can cause some things to shut down due to insufficient voltage. In addition to that, some cars might disconnect any electronics th... |
How does your brain know to wake up earlier than usually when you have something to do for the early morning? | I think it's more that you sleep lightly because you're anxious about having to be up early. I get it all the time and I know that's how I feel before having to wake early it also makes me feel less tired in the morning as I'm not being awoken from a deep sleep. |
Why can atoms not have a nucleus made from neutrons and electrons with protons surrounding them? | Electrons are not baryons. They are leptons. The strong nuclear force that holds the nucleus together is only between baryons. You can get the reverse charge with anti-matter, because the anti-proton has the same charge as an electron, but it's a big old baryon. |
Why is it we can see the inside of our eyelids when we close both eyes, but not when we close one? | How often do you notice your blinks? Almost never, unless you are specifically thinking about them. However, if the lights went out for that long or someone covered your eyes, you would totally notice it. It's because your brain has evolved to pay attention to the important things and ignore the unimportant ones. It kn... |
If we can't get under 7nm with silicon why are intel/AMD not building bigger dies with more transistor instead of always shrinking? | First, we can indeed get below 7nm. There are plans for 5nm and even 2nm in the future. The real reason they don't want to produce larger CPUs is due to cost. The cost of manufacturing a single silicon wafer is pretty much fixed. The more CPU dies that they can get out of each wafer means that each CPU is cheaper. |
How do humans selectively breed plants? | Usually, they find related plants with desirable characteristics and breed them with each other , then select the offspring that express both/all the desired characteristics. Often for commercial seed production they'll breed two different strains, each with some of the desirable characteristics, so that only the first... |
Why do the Canadian and American dollars fluctuate so much? | Think of a nation's currency like a commodity, like maple syrup and apples. The value of the thing goes up and down with supply and demand. The demand for a nation's currency comes from the nation's economy, since that currency is used to perform transactions in the nation. When people are buying and selling lots of th... |
Why does light instantly disappear and not linger. | It's because light moves so incredibly fast. Let's say that you're in a mirrored room where the mirrors reflect 99% of the light they receive. So, each time the wave of light hits a wall it loses 1% of its intensity. If the room is 10 meters across the light will cross the room to the other wall in 33 nanoseconds. With... |
Are gas giants really just giant blobs of gas? | Yes and no. In astronomy, terms like gas and ice are a little different from common use. Rather than strictly meaning it's a gas or a solid, etc, it refers to how certain compounds would be at a certain temperature and pressure. For example, Neptune and Uranus are considered ice giants because they contain large amount... |
What happens when we pop our ears underwater to equalize? | There's a tube that connects your middle ear to your throat, but it's usually closed to keep water or whatever else is in your throat from going up into your middle ear. When you pop your ears, what you're doing is opening that tube, which allows air to flow between your middle ear and your throat, and thus equalizes t... |
How does the moon’s gravity pull water in the ocean, but not other objects? | Other things are affected, just very slightly. The effects of gravity are in proportion to the mass of the object. The ocean is very very very heavy. A fish isn't. |
How do air fryers work? I'm always baffled at the fact that air fryers can produce the same texture as conventional oil fryers. | As opposed to regular fryers, where what you're frying sits in actual boiling oil, air fryers use hot air to vaporize a small quantity of oil that then fries whatever you're frying. The combination of hot air, movement and vaporized oil produced the same frying effect on food, albeit with a fraction of the oil . |
What is our goal for humanity? Is there a goal for humanity? | Between the over 7 billion of us there are, you're going to get quite a few very different and sometimes contradictory answers to such a broad question. I'd like to think that in general, most people's goal for the society they live in would simply be to make life easier for everyone living in that society, but in prac... |
How did Einsteins theory explained the orbit of Mercury? | Planetary orbits aren't exactly round. They're elliptical, with one of the narrow ends of the ellipse being closer to the star. [Like so]. Mercury is close to the sun, moves fast, and has an unusually elliptical orbit. That makes it easy to track and get a lot of data in a short time. So anyway, the orbital path preces... |
What is electro-static discharge (ESD), how does it work and why is it harmful to some electronic devices but generally tolerable for humans? | Short version is electronics are good at conducting electricity to the point of then breaking or burning due to over load. The skin of a human has a high amount of resistance so we are able to tolerate it to a point. While motherboards have electricity flowing through them regularly, an ESD shock puts a lot more stress... |
How do we grow seedless grapes (or other seedless fruits)? Don’t we need seeds to regrow fruits? | Grape farmers never plant grape seeds. Same with apples, pears, peaches, basically any commercial fruit is grown from cuttings, rather than seeds. They're *clones*, and people have been cloning them since at least 1500 BC. All you need to do to clone a plant is to cut a piece off with a knife, attach it to a new root c... |
How can it keep snowing for months on end in winter even though water isn't evaporating. | Wind. Lots and lots of wind. Water doesn't have to evaporate anywhere near where you live. It probably came from the Pacific ocean, then was carried from there by the wind before finally falling. That's where most of the USA gets its water.Water is **always** evaporating somewhere. Look up so weather radars and you wil... |
How does running water get from a water tower into the plumbing of your house, and eventually have enough pressure to come out your faucet? | The first part may sound simplistic but there are pipes connecting the water tower to the plumbing in your house. They start out really big and get smaller the closer they get to your house. Water pressure is a bit more interesting of a story. The reason that water towers exist is to make sure that there is always enou... |
Why do bone cancers have to end up with the whole limb being amputated? Can we just put a metal rods/joints in there instead? Like knee/hip replacements? | The goal of surgery is to remove the bad bits. If you leave any bad stuff behind they can just make more bad stuff grow later. If you have enough bad stuff in your arm/leg you sometimes have to take away a lot of your arm/leg to make really sure you get all the bad stuff out. Joint replacements are used mostly when you... |
What is a pyramid/ponzi scheme? | Pyramid Schemes and Ponzi Schemes are different. & #x200B; Pyramid scheme is when you have a structure that sends money from lower levels up to higher levels. Each person tries to get several folks underneath them. If you look at the structure, it looks like a pyramid with lots of folks on the bottom layer and fewer an... |
If fine motor skills can be improved by practice and repetition, why can handwriting remain messy, despite writing hundreds of words every day? | practice and repetition do not improve a skill, except possibly in the speed you can perform said skill at. Practice and repetition of the **correct** way to do something does improve skill. For example, if you think that 2x3=7, and you practice and repeat that, your math skill will never improve because you're practic... |
can you convert sound energy into a renewable energy source? | Most of what is generally called sound pollution is relatively low in amplitude. Based on what I know about piezoelectrics it would certainly be possible to get some current out of low grade sounds, but the amount would never be economical. When I read the question my first thought was curiosity of what you might get o... |
why are bugs attracted to the indoors? And why do they struggle to go out the window once they’re in? | There are a LOT of insects. Some are bound to get on on accident. You just don't notice all the ones outside, or even the ones that try to get in but fail |
how come there are infinite sections between two numbers | When I was in middle school my teacher did a demo on cutting the distance between you and the wall in half. So, start at one side of the room, and cut the room in half. Do it again, do it again. How many steps would it take to touch the wall? After a couple of these you are VERY close to touching, but due to the remain... |
why do people with a higher income have to pay higher tax? | It's the most obvious thing to do for government. If it is flat, you have 2 choices. Make the rate high, so you can still fundraise the same amount, or make it lower, and you get less money. Less money is not a good option, high taxes would be too burdensome for poor people and they would revolt. The obvious decision f... |
Why does a lower pressure result in a more powerful storm? | Air flows from high to low pressure. It's like a ball rolling down a hill. The higher the hill, the more speed the ball will pick up. And you can make the hill higher either by raising its peak or by lowering the bottom. Similarly, for a powerful storm, you need air to flow from an area of very high pressure to an area... |
What causes people to vomit when seeing something that disgusts them? | The reason why our body does this is evolutionary. Many centuries to millenium, when we would eat something poisonous, our bodies would vomit as a part of the process of getting rid of it. Those who vomited had a better chance of living than those who didn't because the vomit would rid of the poison in an effective way... |
Why are illnesses like a cold or aggressive coughing more common in humans than in animals? | The dog version of the cold is called kennel cough, and it has many causes including the bacterium *Borditella bronchiseptica.* However, it's much more common that the cause of any given kennel cough outbreak is a strain of canine flu. Dogs that spend a lot of time around other dogs, such as at a dog park, doggy daycar... |
Why is there a credit option when paying with debit card? | To add to everything, some banks charge for using your pin anyplace other than their bank, so you run it as a credit. As well as there's time I don't want to put my pin in because no one else needs to know it. |
Does spicy food damage your taste buds/ability to taste? | Basically Capsaisin, the chemical that tastes spicy, makes heat receptors in your mouth activate at lower temperatures than normal. If your body heat is 37c , and the receptors are activating at 35c , your brain will receive a constant barrage of impulses where it literally thinks that your body is being burned. This i... |
What makes carbon fiber stronger but lighter than steel? | Carbon-Carbon bonds are stronger than the metallic bonds holding metal atoms together. There is a lot of energy in these bonds, that's why coal and natural gas make good combustion fuels. It's harder to control the bonds, so it's not a natural process, like some metal formations. |
Are there specific reasons why sexual assault and rape are so rampant in the Catholic Church? | My assumption is that it's a combination of religiously reinforced sexual repression mixed with plenty of opportunity, but as a person that is both not religious and not a sexual predator I can only guess. |
- Why in movies/tv when there’s a hole in a plane passengers are sucked out, but when people skydive and the plane opens they can stand at the edge seemingly easily? | Standard altitude for sky diving is 10,000 feet. Highest in USA is 18,000 feet, and for that you'll need to wear an oxygen mask so you can breathe. Commercial aircraft fly at up to 43,100 feet. Commercial aircraft are pressurized, so you can breath. When they get a hole, their pressurized air rushed out of the aircraft... |
Is there a practical reason for a car's driver to be on the side rather than the middle? | Visibility. If you've ever driven a left or right handed drive in a country that predominantly uses the other system, you'll learn real fast why the seat is where it is. It's annoying to see anything ahead of you safely when you're on the wrong side. |
what is involved in the growing of Bonsai trees that differs from regular plants? How do they make them look like scale model trees? | They're regular trees that have their roots smashed into a smaller area which restricts how much they can grow. They also prune them and clip them meticulously to keep them to very artistic shapes and tiny sizes. They have to be cared for with tons of attention.Its usually just a matter of constraining growth. This is ... |
How and why do harmonics work on a stringed instrument? | When you pluck a string, you get a wave. But, it's not a simple wave with even ups and downs. It has different frequencies. It's a messy wave. All those messy ups and downs create different noises in our ears through different air compression, and it doesn't sound like chaos because it repeats. Put all together, we hea... |
When using slow internet, why do some web pages load bit by bit, while others show nothing until the full result appears? | To clarify, as a web developer, it's entirely up to how the developer to choose the behavior of how a page will appear while loading, and what loads for that matter. By default, content will be loaded as it comes in, the classic example being a plain, Word-like document with pictures that suddenly pop in. However, it's... |
Why aren't old films that can't be remastered with the old reels not just remastered digitally with algorithms or upscaling software? | Old films don't have a resolution, theres nothing to upscale. They also suffer from degradation if they were not stored correctly. Then theres the cost of the film itself, it wasn't cheap leading to a lot of knock offs or other inferior quality products that *really* didn't last long even if stored well. So you have to... |
Why 10? What is the appeal of 10 base numbers that makes everything easier? Why couldn’t it be 8 numbers? | Base 8 and base 12 are number systems that absolutely exist. Base 12 has advantages in every day Life due to how many things are base 12. If you're familiar with computers you already use a non-base 10 number system: hexadecimal! This is a base 16 number system where you have 16 characters. It counts like this: 0,1,2,3... |
why do gears multiply forces ? | Gears convert between force and distance. You can see this with [pulleys], which function just like gears. If you want to lift 1 ton, to about 1 meter height , you can use a pulley system and apply 50 N of force, but you have to pull a long distance, 20 meters of rope, to lift that ton by 1 meter. You're trading effort... |
Why is the MLB season so much longer than other sports? | The biggest reason is money. More games means more chances to sell tickets, hot dogs, beer and television broadcasting rights. Convincing the owners to cut the length of the season would mean asking them to give up money. Conversely, lengthening the season even more would exhaust the players and perhaps force them to p... |
What causes bees to be fairly calm and passive, but wasps and hornets to be total assholes? | From what I undestand, unlike bees, wasps and hornets use attack chemicals to trigger everying in a nest to attack an intruder. When they detect that chemical they become vicious little killers. Not only will do do that on purpose if you get too close to their nest, harming or killing one will release the stuff and onc... |
If coke is so corrosive, how does it not corrode the bottles they put it in? | Did you learn NOTHING from Breaking Bad? Even hydrofluoric acid won't eat plastic. Flesh, bones, metal - but not plastic.Coke is not corrosive, this is BS, there is a Snopes page on thishttps://_URL_0_ |
What is the difference between venomous and poisonous? | If it bites you and you die, it's venomous. If you bit it and you die, it's poisonous. If it bites you and it dies, you're poisonous. And if you both bite each other and no one dies that's kinky.Venom is something that is injected. So a snake bite or spider bite as examples. Poison is ingested . An example is nightshad... |
what causes servers to crash? | A lot of things. * Software bugs* Mistakes made during administration* Disks failing* Power supplies failing* Defective components * Problems with the infrastructure Also, you're often talking about specific, custom-made parts. You don't have the normal CPU fan, you have one that's [custom-made to fit into the thin ser... |
You can locate an airplane when you hear one with reasonable accuracy. Why is it so much harder to locate a helicopter? | Helicopter pilot and long time crewcheif in the Army. It's because of echoes. Your ear has a difficult time locating a helicopter because the sound seems to be coming from everywhere. |
Why does hearing certain noises (such as nails on a chalk board or, for me at least, cardboard scraping against itself) cause bodily discomfort? | Finally someone else who understands the cardboard thing! I've received some odd looks when asking people not to tear or rub cardboard together |
What, in it’s simplest terms, is Pi? | It is the exact ratio between a circle's diameter and its circumference. That it happens to have the 3.141 .. value with infinitely many digits is just a quirk of Euclidean geometry; the number in and of itself isn't particularly special.
