Venezuela Gold Swapping With Deutsche Bank
The Venezuela government is running out of money that was propping up the populist rule of their current dictator. Their efforts to keep critical payments coming for things like the military they are trying to borrow money from other countries, and Deutsche Bank agreed to a cash loan of about $750 million dollars with 20 tons of gold being given as collateral for the agreement. Venezuela failed to make their interest payments on the loan and Deutsche Bank has seized the 20 tons of gold along with dissolving the agreement.

How come people can be so open about their use of illegal drugs on the internet without getting caught by the police?
Once as a teen me and a few friends were smoking out of a big 14-inch bong in a field at the park on a summer night, and a cop walked up on us before we realized he was there. He took in the scene and said, "Hmmph, you guys aren't being loud." And went on his way, clearly annoyed at whoever called it in. So I like to think cops have way better things to do than troll around social media looking for someone who smoked a blunt last week and try to bust him for possession of two grams. Imagine you worked your way up to detective, and you report for your first day of work. "What do we have, chief? A murder? An arms dealing ring?" And chief says, "Even better, I want you to go on Instagram and find out if anyone's been smoking joints in their backyards." Sounds like thrilling police work. I'm sure it's different in the south or more rural places but the general principle would still apply

Can people be sensitive to lightning or thunder storms?
This is a good one. I know that if you were to capture a landscape on film during a thunderstorm and in superslowmotion you'd be able to see tentacles of lightning coming out of the ground prior to the impact of the lightning. For all I know that could cause a static field. Im unsure about the ring if it's possible that would become a conductor or have a current running through it due to that phenomenon. I'm also very curious if people can explain this one. Fun fact by the way. It's better to be hit by lightning directly than a strike close-by. If the lightning starts running along the ground I could go up your leg and down the other. The greater the distance between your feet the more dangerous it will be. That's why you'd sometimes see dead cows without a clear impact damage to the body.

IIRC coffee works by blocking adenosine receptors in the brain, so how do it perform in the early morning when there is little to none adenosine in the body? The spelling is probably wrong too ...
Adenosine is always present in your brain, in significant quantities, so there is always some to block.

An engineer designs and plans things, not builds them. Theye will do all the math and science to design a bridge that can handle super intense traffic in the worst conditions, but they aren't the one laying the concrete. An engineer is a problem solver. Electrical, structural, or mechanical it's all about the same. The engineer is going to try and design something that fixes the problem.

How does drinking water help fiber pass through your system?
Generally speaking, fibre in your bowel attracts water, like a sponge. You can imagine that if you don't have much water around, the sponge is still partly dry and sticky, which makes it harder to push through the gut. If you are well hydrated enough that there is plenty of water for the sponge to draw out from your gut capillaries, you will have a nice, soft, wet sponge to push out instead.

What is a private equity firm?
A private equity firm utilizes money from limited partners (investors - typically members of the firm and outsiders like pension funds, wealthy individuals, institutions, etc.) to purchase companies, do something with them that ranges from holding, to re-organizging, to merging with other companies they acquire, to splitting up companies. & #x200B; Typically private equity firms buy companies \_with leverage\_. For example a $100M software company with a $200M valuation might be purchased for said $200M by the PE firm. The firm will put in 20M and a bank (or group of banks) will put in 180M. The PE firm places that debt \_in the company they just purchased\_. The firm then needs to re-org the company such that it can pay down this debt - this is why they often fire top management, do massive restructurings, etc. This means that "success" to the PE firm means that the company can pay of this debt ITSELF and then the company can be sold - it doesn't even need to be sold for more money and the PE firm makes a profit because after 5-10 years of paying of its own debt the debt is now significantly smaller meaning a sale price that is the same as buy price is actually very profitable since all the proceeds go to the PE firm, the bank was just making interest. & #x200B; Most PE firms create "funds" that are managed by different directors in the firm - they then raise a next fund and a fund after that which each fund typically having a target lifespan of about 10 years. Their ultimate goal is to create return for investors. It's "private equity" in that they are buying corporate equity, but not on the public market (or if they are buying public equity it is to "take it private"). There are lots and lots of variants of private equity firms too.

How does reverse psychology work?
Reverse psychology is defined as "the principle or practice of subtly encouraging a behavior or belief by advocating its opposite." For example: If your parents wanted you to go to college, but you didn't want to, they could say something like, "That's okay. You should just become a plumber, you probably don't have what it takes to get a degree." For the reverse psychology to work, you would then have to try and prove them wrong. So you would go get a degree to say, "See, I can do it" , and that would have been your parents goal the whole time.

How does a proton completely change the element?
Protons don't matter much directly, but electrons do. Protons are positively charge and electrons are negatively charged. To have an atom that is not charged either way the electrons and neutrons must balance each other out. If you have an atom and just at a neutron nothing much changes chemistry wise, but if you add a proton (which is pretty much the same as a neutron except for its charge), the charge of the atom itself changes. To get it back to neutral an electron needs to be added. Electrons can't just join the atom wherever they please, a number of forces and weird rules dictate a complicated pattern in which electrons cluster around an Atom. This pattern of electrons dictates how the atom will join up with other atoms to form molecules by sharing electrons. Think of plastic toy building blocks with patterns of connectors all over them. The Placement of the connectors dictate how you will be able to connect them. Elements with similiar arrangements of electrons in their outermost layer will behave similarly chemistry wise. The pattern in which atoms form up and create larger molecules dictate the physical properties of the substance. Getting from atoms arranged in a special type of arrangements on a microscopic scale to physical properties on a human scale is not really easy to follow, but it is how it works.

why do you see that black spot in the middle when you look at something bright
The black spot you see in the middle WHEN you look at something bright is due to the optic nerve in the back of your eyeballs having no photoreceptors on it. The black spot you see AFTER you’ve looked at a bright light is due to your brain damping the signals from the photoreceptors that are getting the bulk of the bright light shine on them. This takes about 10 minutes for your brain to bring back up to full sensitivity. Eye patches on pirate-day sailors were often used so that a sailor could switch the patch from one eye to the other when they went belowdecks and not be blinded by the darkness because the exposed eye was already adjusted to the dark.

what's the difference between attraction and fetishism? and why is fetishism considered rude in some situations but not others? (think like the embracing of foot fetishes)
I'll be upfront about this. Having a fetish is not considered 'normal' by society and lots of people have a hard time comprehending that this sort of thing even exists let alone is far more common place than they could imagine. A fetish is being attracted to a thing or an action to such a degree that you can't be turned out without it. People with a fetish may have difficulty differentiating between being attracted to someone because of their appearance, or personality, etc or being attracted to them because they happen to be wearing something or performing an act that you fetishize. This can lead to them being in relationships for the wrong reasons, and being taken advantage of. Some people with fetishes have difficulty in relationships because of it. They can't be aroused without their fetish and their partner has to be aware of this and a willing participant and so the sex life can be difficult. Some people are honestly creeped out by fetishes and discovering that a potential or existing partner is into this sort of thing can unfortunately result in disgust and generally bad reactions towards it. The key thing of course is communication, discussing this sort of thing openly with a partner is healthy but since many people are closeted with regards to their fetish because of the taboo they can have a really hard time with this. Having a bad reaction to it can lead them to be even more closeted instead of embracing this part of themselves and exploring it in a healthy way.

Why can you see the colour of the sky within the shape of a crescent or half moon?
The sky is between you and the moon. Not enough light bounces off the dark side to overpower the blue sky, which is caused by sunlight interacting with the atmosphere. Space is not blue.

When switching from one WiFi to another, how come it shuts off the internet while switching, and can’t pass it over without an interruption?
its possible to have multiple wifi routers/access points setup on the same network and have no disruption. & #x200B; if you are changing to a new external IP, you need to successfully authenticate on the new network, get a new ip on the new network, the router needs to add your mac to its address book, and then you can start resending packets that havent been responded to. & #x200B; To have no interruptions, internet DNS servers would have to know where you are going BEFORE you switch, so they could anticipate and send packets to the new router, which of course is a new route. afaik that doesnt exist yet. this COULD work similar to when you move, you need to tell the usps where youre going BEFORE you move if you dont want an interruption in mail service. & #x200B; with the internet, it would simply take too many resources to manage and what happens if you decide to connect to starbucks wifi instead of pete's? just a bunch of wasted traffic. much more efficient to have a small delay and know exactly where you are, than where you think youll be.

Why are some clouds darker than others? Is this water saturation and if so, how does this work with light and fluffy(very technical term) clouds?
The perceived darkness of a cloud depends on which part of the cloud you're looking at, how dense the cloud is, the sun's orientation to the cloud, and your orientation to the cloud. Let's say there's a dense cumulus cloud overhead. Cumulus clouds are relatively low in the atmosphere. If you can see the top of the cloud, it's white and fluffy because light from the sun bounces off the millions of tiny water droplets. If you're under the cloud it looks dark because you're not seeing the sun directly bounce off the bottom of the cloud. The millions of water droplets block the sun from reaching the bottom of the cloud. The wider and taller the cloud, the less light will reach the bottom of the cloud. If there's a high, wispy, cirrus cloud in the sky, it's not a very dense or tall like the cumulus. Its low density allows most of the light to pass through, so it's a little grey, but not as dark as the bottom of the cumulus cloud.

Some kid at school says he'll buy as many snack packs as you can find for $20 each. You skip class to clear out the grocery store but you never find the guy to make the deal, you try to sell them to other people but no one is very enthusiastic about it. So you sell them dirt cheap for the rest of the school year and everyone hates you for pushing them anymore -- what used to be a decent trade good is now rotting in people's lockers because they can't stand the stuff anymore. Not only do you lose a ton of money but also everyone thinks you're a fool. Now you're extremely leery, Not just of "too good to be true" deals, but every deal.

Why do flies spawn out of banana peels? How do they always get there?
The classic experiment disproving the theory of generation was conducted in the 1700s, but you can do it at home too. Leave a banana peel out in the open, on your backyard, while leaving an identical banana peel in a sealed, airtight container. You should notice after a few days that flies start appearing out of the first banana peel, while the second banana peel doesn't.

Why do stars seem much brighter when I'm looking at them from the corner of my eye?
When you look at them via the corner of your eye, you're using the "rods" part of your retina. The rods are much more light sensitive than the cones at the center of your vision. However, rods don't see much in the way of color. So you have the light sensitive but not color sensitive rods around your periphery and the color sensitive but not light sensitive cones in your central vision.

When experiencing (heavy) turbulence it somtimes feels like the airplane suddenly drops a few feet. Does this actually happen or what causes this feeling if it doesn't?
You feel that sudden drop because the plane is in fact moving slightly downwards. This happens for the same reason your feels like it's going downwards when you go down a steep slope. The only difference is that your car drives on pavement/ground, and a plane flies on top of high pressure air. Wings create a pressure difference, high pressure on the bottom and low pressure on the top, this is how they fly. Turbulence is caused by an uneven pressure difference when flying through certain areas. This creates a difference in lift which causes the plane to move up or down. The simplest way to put it is like driving down a rough road in a car. It's not dangerous, it's just unpleasant.

Why do humans weigh less when they wake up compared to when they fall asleep.
Strictly speaking, you probably don't lose any meaningful amount. Your weight fluctuates during the day, mostly due to water retention or loss in response to hormonal changes. During the night cortisol levels drop to their lowest levels in the day, this is a hormone that promotes water retention (among other things). You also sweat and continue to burn calories despite not eating or drinking while asleep, so it would make sense that you are at your lowest weight as soon as you wake up. However, you have probably only lose a negligible amount of body fat, it any, and it's mostly due to water loss.

What is white noise?
Radios have an "automatic gain control" (AGC). When the reception is weak, the circuit that deals with the radio frequencies turns up it's amplification to try and get the best signal it can so it can then extract what actual audio it can. When the gain goes up to maximum, all it ends up amplifying is noise, radio interference from outside and random electrical noise generated inside the circuit components. There might be a weak signal hidden in the noise so you may hear a noisy radio signal as well, so it wouldn't just cut out.

; After reading the post on the adenosine blocking features caffiene has I have follow up questions. Is that the same process that pain killers have? And does the fact that it has to make new paths aid in the memory loss that painkillers (opiods specifically) give you?
No, the over the counter meds typically are COX inhibitors. Interrupts a chemical pathway that causes pain and inflammation. Doesn't have a receptor. Opioids don't cause memory problems. They cause central nervous system depression (read suboptimal processing). You don't remember things well because it stunts your brain's ability to process things. That's why they help with pain. Makes it easier to ignore.

Why do some animals have tails?
Depends on what kind of "why" you're asking. If you mean "what function does it serve", it varies from animal to animal, but one of the most common uses is for balance. If you mean "where does it come from", it comes down to natural selection: some individuals developed longer tails, that were useful for whatever reason in specific environments, and so those wity shorter or no tails died out or migrated to environments where their tail length was more benefitial, and thus their descendants inherited those traits. If you mean "how did it come to be in the first place", it also comes down to evolution, but it's a more specific awnser this time: it's simply the result of bilateral symmetry. It was extremely useful for moving in water (compared to biradial simmetry, more suited for static organisms), and thus most if not all mobile animals, descended from whatever specimen first developed it, are symmetric. Tails are just appendixes that develop at the end of the body, and can be useful for many things, including balance, so it's no wonder so many animals develop it. But a more "unified" tail is that of vertebrates, which, in many cases (excluding cases like horses, in which "tails" are just strands of hair) are the same: the vertebral column extending past the cervix (hip bones).

Why is flat fizzy water so gross when compared to just naturally flat water ?
Carbon dioxide doesn't dissolve into water the same way most gases do. If you dissolve oxygen or nitrogen into water, the oxygen and nitrogen remain unchanged, and are just spread out throughout the liquid. When you dissolve carbon dioxide in water, most of the carbon dioxide actually chemically bonds with the water to produce carbonic acid. Given enough time, this carbonic acid will react with the water, with other molecules of carbonic acid, and with any other random things that just happened to be floating in the water and produce a bunch of other carbon chemicals, many of which have a weird taste.

; Why is dark skin selected for when you’re in the sun a lot? Dark colors absorbs most visible light, while white reflects it. Is it different for UV light?
Because the upper layer of skin is dead anyway. That dead layer of skin absorbs a lot more of the radiation from the Sun than it would if it was lightly colored, which helps protect the skin beneath it. This is white dark skin people don't get sunburn nearly as easily as fair-skinned people. Darker-skinned people do technically absorb more heat from the Sun than lighter skin people, but compared to the amount of heat that the body is producing naturally through its own metabolic actions this difference is negligible.

WBA, IBF, BO and IBO are all different boxing organizations. Imagine it more like there was an NBA, and a Southern Basketball League and a Northern Basketball League and a World Basketball League and a International Basketball League and all of the same teams played. You could have one team hold the titles for all of the leagues. With boxing, there are different federations, organizations, associations etc with different monetary backers and different prestige. What tends to happen, is that champs from different organizations fight each other to "Unify" belts. So one fighter will take 2 or 3 belts off of one champ to "unify" them under one holder.

How do explosions kill? Like grenades and other explosives.
If you're very close to the blast the concussion itself can kill you. The shockwave can easily transfer energy from air to a denser material like your body, but the transfer back into air behind you is very ineffective. That means you instead have to absorb all that energy, and all the hollow pockets in your body don't like that. Concussion drops off quickly with distance though, so for most explosions the real hazard is shrapnel. The explosive device and anything brittle nearby gets shredded into fragments and launched outward at great speed. These fragments do the majority of the damage further away from the point of the explosion. Some weapons (like fragmentation grenades and terrorist IEDs) are specifically packed with shrapnel to maximize this effect.

how do animals without parental training know how to be the animals they are?
First, if I were to cut your skull vertically and take a look at a cross-section of your brain, I'd be able to divide it into what you normally think of as the brain (the noodlely bits) and the brain-stem. Most of your instinctual functions, such as curling away from heat, your fight or flight instincts, reflex to swallow things put in your mouth, etc. are all handled by the brain-stem. Animals that don't require parental nurture often have their behavior programmed into them. They're extremely complex chemical reactions at the end of the day.

Why do animals get away with not brushing their teeth, but human teeth will not last without regular brushing?
It is in what we eat. Certain things we eat destroy the enamel that protects the fleshy part of our teeth (pulp). Namely cane sugar. Once the enamel is compromised, it is easy for the pulp to rot. Animals are not completely immune to this. Dogs, for instance, develop issues with tartar and plaque buildup that can lead to rotting teeth. In the animal world, the tooth will eventually just fall out/break/rot to nothing. It just happens that most animals (especially the carnivores that require sharp teeth to eat) only eat things that could never cause tooth decay.

The object will still loose energy as radiation. The rate rate will depend on the cube of the temperature so the warmer it is the faster it will loose heat. So it is a possible way but the better question is if it is a efficient way. To store heat efficiently you like a large mass with small surface area because then i will cool down slower. There vill be a relative small area exposed to the sunlight in a system like compare to the mass. A better way is to have large area where you can collect solar energy and transport the material to a storage area where it is more compact. The most common way to do that is [Solar\_water\_heating](_URL_2_) where heat water in large collectors and stor it in a tank. You can stop the water flowing to the collectors when the do not add energy. That result in small surface area for storage but large for collecting light. The storage tank can be isolate to reduce the rate that it looses heat and you could have vacuum as a part of it. A regular [thermos](_URL_0_) uses vacuum for isolation. I suspect that is it not cost efficient for solar heating because you can have thick layers of cheaper material that is not conductive if it cool down to fast with just a tank. System like that work for heating housed and create warm water but not efficient create electricity. To create electricity you like higher temperature difference. You can use mirror to create steam from water directly and drive turbine or lik in the [Crescent\_Dunes\_Solar\_Energy\_Project](_URL_1_) use mirror to heat up molten salt instead of water. Regular table salt melt at 800C( 1473 F) and boil at 1465C (2669F). So you you high temperature range and can use it to create steam from water and drive a steam turbine to create electricity. & #x200B; So it would work but is not efficient. Water or liquid slat can be stored in large tanks that will loos energy quite slowly and you can use a lot larger area to collect the energy. heating a solid is not ass efficient because you cant pump it around.

What causes that burning/tickling sensation felt after a failed sneeze?
A sneeze is triggered (generally) after a buildup of stimulation crosses a certain threshold. Your nose has to be irritated enough to actually set off a sneeze reaction. If you get close to crossing that threshold without actually going over, your nose is still stimulated and irritated, but not quite enough to actually trigger a sneeze, so you’re left in that insufferable pre-sneeze limbo. It’s like getting close to an orgasm and then suddenly stopping stimulation.

Why does caffeine make you pee so often?
Your kidneys first filter out your blood, then reabsorb some of the excess water to concentrate your urine before it goes to your bladder. Diuretics like caffeine and alcohol let more water flow out of your blood in that initial step, and since it can only reabsorb so much, your kidneys end up producing more urine.

why is it easy to cross your eyes, but almost impossible to have each eye point outwards (left eye looks left, right eye looks right)?
Our eyes are designed to follow a straight-line path to an object (which is called *looking at it*). The reason our eyes narrow is that they're a distance apart, so the closer an object is to you, the more extreme of an angle they need to turn relative to each other in order to focus on it. That's the obvious stuff you can observe just by feeling how your eyes move when you look at something. The trick is the reverse: objects that are extremely far away. Let's take the sun. It's a fantastic example. Light radiates from it in a sphere. However, we are so far away from the sun that all the light that strikes the earth (and especially your eyes) is basically moving parallel to itself, since the aiming from that distance had to be so precise. If you follow the paths the light took back to the sun, your eyes would wind up nearly parallel with each other. And if you looked at some hypothetical object infinitely far away, you'd *have* to be looking in parallel lines in order to see it. There is no situation on earth where you can see something more clearly by having your eyes turn any further outward than that. Any attempt would necessarily mean you lose all the benefits of binocular vision (two eyes facing forwards).

Why do some medications have expiration dates while others don't?
Maybe this depends where you come from, but I understood that in the US, medications MUST have an expiry date. A lot of "Expiry dates" on medications are artificial. The medicine may be entirely fine after that date, but the company hasn't tested it so they can't guarantee full effectiveness. In other occasions, the date is merely the date that the medication is supposed to be 100% effective. Some chemicals break down and become less effective over time, but even if you take an Aspirin a few months after expiry, the odds are very high that you will still get like 95% effective medicine if not 100%. So unless the medication is life-saving or life-preserving (e.g. an epi pen or a medicine that keeps your heart running or whatever), you are frequently safe to use the expired stuff. Particularly something like an over the counter pain killer that will still do a reasonably effective job. the US government buys a large amount of drugs for people like the military, and after having to throw out and rebuy a lot of the drugs upon expiry, someone did a study and discovered what I noted about the drugs still being pretty much fully effective after that date.

Why does the change in pressure from driving over a mountain make things sound quiet/muffled?
As you go up, there is less air pressing on the outside of your ears. The inner ear is sealed by little tubes that open when you yawn. When the pressure inside the ear is more than the pressure outside like it is when you're going up, the ear drum becomes tight, almost like an inflated balloon. When you yawn - and sometimes while you're chewing - those little tubes (called the Eustachian tubes are not in your head :P. tubes) open up and let that excess pressure out until the pressure inside your ear equals the outside atmosphere. The pop you hear is a combination of the tubes opening and that air rushing out into your sinuses. This makes your eardrum loose again, allowing it to vibrate properly to pick up the sound moving through the air! Edit: Corrected Google changing my (likely horribly misspelled) word! I might be uninstalling Gboard after this.

Do animals in the wild get enough sleep or are they constantly sleep deprived?
Circadian biologist here: many animals sleep in ways that are very different than humans. For example, ducks rest one side of their brain while leaving the other side awake to allow them to literally keep and eye out for predators. Many prey animals, like rats and mice, have very short bouts of sleep over a 24 hour period (from 20 seconds to only a few minutes). Sleep deprivation is usually defined by seeing an increase in slow wave activity during a sleep bout after an extended period of time awake. This has been documented in female frigate birds in the Galapagos which will fly constantly for days at a time while feeding before returning to their nest to feed their young. Since frigate birds cannot take off from water, they must remain in flight the entire time they are foraging. Researchers have shown that during that flight time, the birds do sleep and in fact they will also sleep only one side of their brain while the other keeps that eye open. Then when they return to land, their sleep shows a similar rebound that we see in other sleep deprived organisms. & #x200B; TL;DR Animals can get sleep deprived, but it's unlikely they live in a constant state of sleep deprivation Frigate bird source: [_URL_0_](_URL_0_)

How are literary devices and writing style captured in translated work? E.g. The Odyssey.
That's a complicated and sometimes controversial process. Some things like rhymes and puns simply can't always be translated effectively and are lost. The English joke about how Seven ate Nine can't work in Spanish, you'll just have to note that it's a joke. Things like tone and connotations are left to the translator. In cases where the original author is long gone this can be tricky because the original intent may be lost to time. That's why you see so many different translations of old works. Exactly what the authors of the Eddas or the Old Testament or the Illiad meant with some word choices is still debatable.

What are stem cells and why are they important in research?
If we took samples from your body of different parts and looked at them under a microscope we would be able to tell the difference between different types of cells. A brain cell would look like a brain cell and a muscle cell would looks like a muscle cell. They both contain a full copy of your DNA, but the brain cell is reading the part of your DNA that instructs it to be a brain cell, and the muscle cell is following inscriptions for being a muscle cell. If we transplant a brain cell into your muscle it will only ever be an out of place brain cell and will probably die. A stem cell is a cell that has yet to determine what "type" of cell it is going to become. Therefore they are very valuable for medical treatment and research. They can teach us a lot about how cells and DNA work, and they are important for treating many genetic diseases.

The word is 'fraud'. But the word you're looking for is chiropractic. The issue you're having is due to "chiropractor" being completely from the Greek \[chiro- (hand) and praktikos- (practical)\], whereas the "ist" suffix comes to us from Latin instead, and so follow different guidelines for fiddling.

why cant we store electricity indefinitely in batteries?
Batteries work by storing electrons between an electrolyte layer. That layer prevents the cathode from making contact with the anode, which would result in a short circuit. When a load is introduced to the battery, it pulls electrons from one side to the other, creating an electric current through the attached device. What causes batteries to lose charge overtime is that the electrolyte is not perfect. Electrons will still slip past it and move to the anode layer, which means the batteries capacity is lowered. When batteries are connected to electronics, they could also be powering part of the device, even if it's turned off. IE: In phones, the battery will keep the real-time clock powered on, and possibly other components, while it's turned off.

Why do some recent films from the 2000s need to go through a remaster process into higher resolutions like 4K? Aren't the original source files already at their native resolution, especially if they were filmed digitally?
No, there was still a lot of film used in the 2000s. Even so, digitization for HD (1080) is very different from digitization for 4K (2160) because different bitrate limits are needed for the different formats. There might have been a 4K "digital" version for theaters with digital projectors in the 2000s, but that's not the right bitrate for an Ultra HD Bluray.

Should everyone be using Tor, the secure web browser, or are there drawbacks for the average internet user?
A drawback for users is that it's slower because your data has to route through layers of relays. It occurs to me that this process is actually worse for the environment too since it requires extra energy to power those relays. I'm not saying that doesn't mean it's not necessarily worth it, but just that there are non-obvious downsides.

Noise canceling headphones works by picking up sound and playing the reversing the sound wave. But how does this happen in real-time?
Imagine you're on a boat in a body of water and large rolling waves are lifting and dropping the boat (something that might make some folks sea sick). To smooth out the water so you don't notice the waves, we generate more waves that exactly match the waves rolling under your boat BUT, we shift them forward 180 degrees to "fill in" all the valleys between the peaks. This way you feel a "smoother" ride. Best I can do without bringing in the science behind sound waves and the electrical theory behind microphones, speakers, and noise cancelling circuitry. Just remember, sound is slower than light by a long shot. We can take in that noise, cancel it, and replay it with very little lag time.

Why are utility poles made of wood?
wood is cheap and nonconductive. light poles where the wires are stretched from pole to pole can be wood as well. but light poles where the wires go down into the ground need to be hollow because you don't want the wires exposed to pedestrians, and that's easier with metal since it still needs to be sturdy and thin (since they're often placed by sidewalks that they'd otherwise block)

Why is it that when human beings can adequately hear a song they like, they still have a biological or psychological urge to turn it up?
It’s quite simple: Things that you like sound “better” louder. The frequency response of human hearing is not flat, and it is not linear at every frequency as the volume (amplitude) is increased. At low volumes, humans cannot hear low frequencies or high frequencies as well as they can mid-frequencies. The range of human hearing is roughly 20Hz to 20000Hz. Humans have a very sharp peak in perception of frequencies between 2kHz and 4kHz. As the amplitude increases, the frequency response of human hearing gets flatter, so the low frequencies become more audible and the high frequencies become more audible, and those mid-frequencies become comparatively less audible. So, when it’s louder, it sounds “fuller” and “warmer”, when it’s quieter it sounds “thin” and “cold”.

When people talk about nuclear waste, what are they really talking about? Whats in those scary barrels buried deep in a bunker if it isn't "glowing green goo?"
There are different classes of nuclear waste. Low level radioactive (rad) waste is broken down into different classifications. It can be anything from gloves and paper suits worn in containment or resin beds or filters. It’s disposed in special facilities based on its classification. High level waste includes spent fuel. Nuclear fuel is uranium pellets (sort of the size of an eraser on top of a pencil) that are assembled into rods and then the rods make up a bundle. Once the fuel is removed from the core, it goes into spent fuel pools, which are literally just pools of water. The spent fuel will hang out there for a while, just chilling (literally and figuratively). Eventually, the rods will be moved into longer-term storage. This was originally supposed to be Yucca Mountain (in the US at least). That facility was paid for by operating nuclear plants, but was never opened. Instead, nuclear plants usually move their spent fuel into dry cask storage. This is a big coke can looking thing that just holds the fuel. The fuel is, remember, still in rods. So you just plop it in the giant coke can and seal it up. They hang around outside the nuclear plant. Not in a deep bunker, just like chilling outside. Although it sounds like there’s just nuclear waste everywhere, it’s important to keep in mind that it’s not a sludge (if you’re talking about fuel). It’s a stable solid rod. And the amount of rods we’re talking here is not a lot. In fact, it’s really not an issue at all for plants to continue to store spent fuel on site, it’s just kind of a paperwork pain. At this time, there’s no way to recycle spent fuel in the US (I don’t think).

If you stood in front of a hugely radioactive source what would physically happen to you in the short term? Also would the type of radioactivity change the result?
There are various types of ionizing radiation, which are considered harmful * Alpha (fast moving helium-4 atoms) * Beta (electrons) * Gamma (very high energy photons, which are like light, but not in the visible spectrum) Ionizing radiation is harmful because it can damage cells/DNA. Symptoms depend on which cells are damaged, and how much radiation you receive. Depending on the dose, and which body parts are affected \- skin can burn \- bone marrow/blood vessels will lose white blood cells; weakening your immune system. \- you can get internal bleeding in your digestive tract \- inflammation and scaring in the lungs. \- Lots of radiation to the brain can cause seizures. Also, as with any kind of cell damage, there's an elevated risk of cancer (skin cancer, thyroid cancer, etc) as damage to DNA can result in mutation. The thyroid is fairly susceptible. (This doesn't mean you definitely get cancer, or it happens immediately. Cells mutate a little whenever they divide and a mutation may take 30 years to result in cancer). & #x200B; In terms of how dangerous they are, and what is affected, alpha is generally stopped by the skin, beta can penetrate a bit of clothing/skin, and gamma needs a lot of thick shielding (e.g. lead) to be blocked. We measure radiation doses in sieverts which tries to accommodate for the differences in the type of radiation. Here's a good table of the symptoms: [_URL_0_](_URL_1_) And the expected doses are for various things: [_URL_2_](_URL_2_)

Why is negative population growth bad?
Because people like to retire. If you have negative population growth and a life expectancy that is over the age of retirement then you eventually get to a situation in which there are more retirees than people working. The thing about being a human is that humans enjoy consuming goods and services. To produce those goods and services, you need humans who are actively employed in the labor force. Retirees, on the other hand, only consume goods and services without producing any themselves. This means that in our society with more retirees than working people, you end up with a situation in which you have a very low ratio of humans working to provide goods and services compared to humans consuming them. This means that everyone has to consume less goods and services, which means that everyone ends up being much poorer. Humans, generally speaking, don't like being poor due to the aforementioned lack of goods and services available for them to consume.

what is the relationship between employment rate and inflation?
Unemployment rate and inflation are both indicators about the strength of the economy. If unemployment rate is too high it means there is not enough jobs available. If unemployment rate is too low it means there are not enough workers seeking jobs. If inflation is too low it means there is not enough currency to support the population which prevents its use and prevents economic growth. If inflation is too high it means there is too much currency to support the population and the currency no longer has value. Either will cause the economy to stagnate. If workers dont have jobs then they dont have money. They dont have money they cant spend it on goods and services. Without jobs, and therefore no money, then demand for goods and services goes down. This causes the need to keep producing these goods and services to go down which increases unemployment. If unemployment rate is too low it means people aren't looking for jobs. If jobs are being created they cant be filled. This causes demand for goods and services to rise and supply to drop. This makes goods and service more valuable increasing their cost.

What causes that indescribable scent when it first starts to rain?
It’s called “petrichor”, and it’s a scent that’s created when rain hits dried soil. Plant oils soak into absorbent dirt over time, and are then released into the air when the dirt starts getting wet. The scent has been isolated and is commercially available as a fragrance material called “geosmin”. The human sense of smell is *ridiculously* sensitive to geosmin, and you can smell it in concentrations as low as just a few parts per *trillion* - one single drop of geosmin in an Olympic-size swimming pool is detectable.

How and why is Earth's orbit elliptical and not circular?
Because perfectly circular is incredibly unlikely, almost all orbits will be at least slightly elliptical. Earth's orbit is only very slightly elliptical, its furthest point from the sun is just 3.4% further out than its closest approach to the sun which is an eccentricity(out of roundness) of just 0.0167, that's pretty round. It doesn't take much to change an orbit over billions of years. A few well timed tugs from Jupiter, Saturn, or another large mass while the planets were finding their orbit could tug Earth into a slightly different orbit. Again, at only 0.0167 eccentricity it wouldn't take much. Pluto on the other hand has an eccentricity of 0.2488 and has a very elliptical orbit because it has been being tweaked by Uranus and Neptune for billions of years.

Think of it like a shrimp allergy. To most of us, shrimp is food. To many it's a delicious, special treat. To some people, even though they may like the taste, their body reacts differently to shrimp and it can cause serious problems. The individual reacts in a non-standard way to a standard substance. Interestingly, there are tons of studies linking impulse control to many other conditions from brain damage to gut bacteria. The extent of our free will is being studied, and may not be as simple as previously thought.

how does a tick bite make you allergic to red meat?
I'm not an expert on this, but I did some reading out of curiosity since I've also heard of this phenomenon but didn't know the details; [this paper](_URL_2_) is the main source I used. The allergic reaction you're asking about occurs in response to a specific carbohydrate known as "alpha-gal". If you want the technical details, it's a disaccharide of galactose that looks like [this](_URL_0_). Alpha-gal occurs naturally in most mammals, but for whatever reason the gene which produces it has been lost in some primates, including humans. Since ticks feed on all kinds of animals, they can introduce this chemical to you when they bite you after biting something else first. Because it is not naturally occurring in humans, this chemical is recognized as foreign by the immune system if it is found in your blood, and triggers the production of antibodies in an immune response. As a side note, this same chemical is also apparently one of the major barriers to organ transplants from non-human animals such as pigs; [this paper](_URL_1_) looks into a possible solution to this by modifying pigs so they produce much less alpha-gal. Just like what happens after you receive a vaccine or beat an illness, your body remembers its exposure to alpha-gal and will keep producing these antibodies for a long time. I'm not totally clear on why this becomes an issue when eating red meat only *after* exposure, but I expect that it has something to do with a greatly increased sensitivity to alpha-gal. Before you got bitten by a tick, you would probably just digest the relatively small amount of alpha-gal you ingested. But after your body finds alpha-gal in your blood, the antibodies it produces make your immune system more "vigilant", and it will start actively searching for any trace of alpha-gal, which is why you now develop a reaction after eating red meat. An actual immunologist could probably explain this part better. So to summarize, when ticks bite you they sometimes inject you with a small amount of blood from their previous victims. If these include non-primate mammals (which could be wildlife, livestock, or pets), then they can pass on alpha-gal, which your body then recognizes as foreign material in your blood. This causes an immune response, and has the potential to make you permanently sensitive to this chemical when you ingest it in the form of meat from other mammals. Since birds and fish do not produce alpha-gal, you can still eat them with no problems. Actually, you'd also have no issues if you just switched to cannibalism, so that's another option!

Why do these equipment have a warning?
It contains a signal booster or transmitter which can emit a few Watts of radio energy. The FCC has two classes of devices, portable and mobile. Your device is considered mobile, not portable. > [Portable devices are normally those used within 20 centimeters of the body and must be evaluated with respect to SAR limits. Mobile devices are normally used 20 centimeters or more away from the body and can be evaluated in terms of either SAR or field intensity. ](_URL_0_) This only explains the 20 cm specification. You'll be fine as long as you don't stick your head right next to the radio card.

Attachment theory in adults and how it can affect someone
Attachment theory is a model used by psychologists to describe the both long and short-term interpersonal (between people) relationships. Attachments are typically formed in your childhood and can predict what the dynamic of your future relationships will be like. The 'attachment' is between the caregiver (a parent or guardian) and the child. There are four main types of attachments that could form, and it's based on HOW the dynamic of your relationship was between your parents and yourself. 1. Secure 2. Anxious 3. Avoidant 4. Disorganized A good way of testing this in a controlled setting is having a parent be in a room with a child, then leave the room, and then come back and console the child. Usually you can infer what attachment style has been formed based on the child's reaction when the mother leaves and comes back. For instance, in a secure attachment, the child will be in distress when the mother leaves and be consoled right away when the mother comes back. The child will come towards the mother, give her attention, and stop crying. It's important because attachment styles in your childhood can carry onto how you form attachments with other people and your own children.

What is stickiness? On a chemical level, what's happening? Is everything sticky in the same way or are there different kinds of stickiness?
There are different kinds of stickiness. Two I can think of are fictional forces, of which Velcro might be a good example (if I'm wrong you will see me swiftly corrected) and viscosity. Viscosity has to do with how much something resists a sliding force. Like the difference between how thick mud flows vs hot oil. If you mean to include adhesion, I'd as chemical bonding. Super glue is a liquid & catalyst chemical reaction that hardens into a solid material bonding two things together. But I don't really think of that as "sticky" even though it's glue. Edit: some great and more educated replies than mine here now. However I stand by my assertion that Velcro is all in your head. Imaginary forces hold it together.

Did old films really looked that bad back when filmed or it's just because it's deterioration over time?
Depending on which version of an old film you saw, it could have even looked worse back then. A lot of the versions you see now have been remastered.

How is profit made from stocks?
Think of it like any other market (for example a supermarket). At its simplest, you buy something at a price, and sell it to someone else at a higher price, pocketing the difference. Some stocks pay dividends, in which case you earn a small fraction of the company’s profits which is paid out quarterly, annually, etc It is also possible to short a stock. Effectively you borrow somebody else’s stock from your broker and immediately sell it in anticipation of its price dropping (due to your outlook on the company, market factors, etc.). At some point you need to buy some more of that company’s stock to return what you borrowed. If the price drops in the meantime, you pocket the difference. If the price increases you have to buy at the higher price and therefore lose money. Shorts are riskier than longs (buying then selling). If you go long on, say, a $100 stock, the very worst that can happen is that the stock becomes worthless and you lose that $100. However, if you short a $10 stock, it could conceivably increase in value by any amount of money. Imagine it jumped to $100, $500, $1000, etc. There is no upper bound

How does a nuclear power plant generate electricity? Where does the radiation come from when there are failures?
A nuclear reactor uses a chunk of stuff that wants to explode. They jam pencils through it to stop it from exploding. It still gets super hot (but not not enough to melt the pencil lead), and they use that heat to make steam. They use the steam to spin big motors that make electricity.

Why does wrapping a bottle/ can in a wet paper towel cool it faster when placed in a freezer
Water transfers heat faster than air does, so the wet paper towel absorbs heat from the bottle/can faster than just putting it in the cold freezer air.

How did the beef between the Chinese government and Falun Gong start?
Falun Gong was a kind of hokey mish-mash of Buddhism, Taoism and qigong exercise. It was founded in 92 and got real popular fast. The CCP was trying to get people to be less devoted to it by smearing it in the party controlled media. The Falun Gong practitioners staged a non violent protest in Beijing (because that has such a great track record). It woke the party up to how much influence Falun Gong had acquired in a very short time and a few weeks later they banned it as a cult.

how did computers get so smart at playing chess ?
Chess is a unique game, in that each piece has only certain moves that can be performed at any time, and thus one can predict which moves will be done many turns in advance, and each move to counter them. There is really no "randomness" in chance. This allows a computer to be programmed to constantly monitor the positions of each piece on the board, and do exactly that, think 10+ turns ahead and figure out each counterplay to each possible movement of each piece on the board, your own and your opponents. & #x200B; It's very close to what a grandmaster in chess does, however, a computer is not subject to stress or other interferences.

How do babies know that they need to breathe as soon as they are born?
The sudden change in temperature and stimuli causes a neurological reaction. Triggering the first breath, which typically sounds like a gasp as the baby takes in air for the first time, rather than being filled with fluid. Much like the Mamillian Dive Reflex, this acts on the same pathway iirc, just in reverse? Been a min since I took those classes...but the first part is correct for sure...the dive Reflex part maybe take with some salt first....

how did iced tea get to where it is today.
It is not the northern states that were left behind. It was the south and Canada who couldn’t see past the sugar to realize the tea was what you were after all along. Add mint, add another tea to the tea hell add lemonade. IDGAF But don’t mock the unsweetened tea just add your sugar and move along.

Why are the back wheels of wheelchairs slightly angled inwards?
That's called camber. Negative camber is when the bottom of the wheels flare out. Negative camber improves handling on turns by increasing the grip on the center of the tire as the forces cause the vehicle to lean on that side. Makes it less likely to tip. Negative camber also provides an outward force on the wheels when going straight that helps it maintain a straighter course.

Why does food taste weird right after we brush our teeth?
Menthol (what makes things minty) actually sets off certain taste receptors in our mouths. Our tongues pick up salty, sweet, bitter, sour and savory flavors. When menthol hits the tongue it basically shuts off the sweet receptors. So when you drink orange juice after brushing your teeth, you only get the bitter and sour parts of the flavor

Why do songs and poems usually rhyme? Why is rhyming so pleasing for us humans?
The human brain loves patterns. Rhyming is just a pattern of sounds. Like how we see faces in odd shapes. It's just a natural thought process to find and enjoy patterns

what's the difference between constant and variable video framerate modes?
* Video is just rapidly changing pictures on your screen which gives the illusion of movement. * Each picture in a video is called a *frame* * The speed at which frames are shown is called framerate typically measured in frames per second or FPS. A constant framerate video will change the picture on your screen at a constant rate. For example a 30fps constant framerate video will show 30 frames a second every second for the entirety of the video. Traditionally, video technologies has always used a constant framerate, most notably film video. Now remember that each frame is essentially a picture and a video is essentially a group of several pictures. If the video was a scene where absolutely nothing moved, we would have several frames that look exactly the same. As a way to save space, variable framerate video finds frames that looks the same and only keeps one copy of it. During playback, it uses that one frame repeatedly instead of using several duplicate frames once. This means that variable framerate video can have the same fidelity as a constant framerate video while also having a smaller filesize. There are drawbacks however. One drawback to this is finding duplicate frames can take some time which makes making a variable framerate video a slower process. Another one is the logic used to identify duplicate frames can be flawed which might mistakenly drop frames that aren't duplicates or keep frames that are duplicates resulting in poor quality or suboptimal filesize.

Why do some apps not include the full functionality of the full website?
Because adding functionality is expensive because you need someone to develop it. Also people use platforms differently on mobile compared to their computer.
