What would I die of (first) if I was suddenly exposed to deep space conditions? For example if my spaceship collapses...
|
If you are in the spaceship, you will be crushed. If you suddenly get exposed to the vacuum of space, the lack of air. The pressure in your body will expand and you will blow up like a cartoon balloon. If you survive that, you suffocate. Contrary to common belief you won't instantly freeze, as heat needs a medium to move through, you will stay a warm corpse for a bit. _URL_0_

What is postmodernism in layman's terms?
|
The best way to understand post-modernism is first to understand *modernism*. This was an early C20th movement that insisted on "honesty" in all aspects of design and creativity. In architecture for example it required that "form follows function" so that you could tell from a building how it was constructed and how it was to be used and not try and disguise it as something else. The corkscrew was seen as an honest expression in its form and construction of exactly what it was but the drinks dispenser disguised as a globe or any plastic object designed to look like it was made from wood was unacceptable. In other areas of culture, modernism resulted in philosophies of good literature, good performance etc and a rejection of all that was fake or frivolous. Post modernism was a reaction against this. Some thought modernism was too "earnest" and limiting and experimented with creating things that broke these rules, New materials meant it was possible to build constructions that instead of looking stable and load-bearing were frivolous and eccentric. In other areas it meant abandoning all the rules of "good design" or "good writing" etc and experiment with ideas that were not hampered like this. So music and writing that combined different genres, everyday objects that were frivolous rather than practical. Imagine the bridge with a see-thru glass floor, or the war-time novel that introduces magical happenings, the oil painting of a cartoon character, the opera based on Jerry Springer - all these are typical post-modern creations and could never have happened during the modernist period.

How does glue actually work?
|
It depends on the glue. PVC glue actually melts the PVC that you apply it to and then the two melted sections that you're gluing harden and form together into a solid joint. Cyanoacrylate reacts with water in the air to form a polymer. Since this polymer started as a liquid it can seep into the many nooks and crannies of an object, and once it hardens it is very difficult to remove from all of them simultaneously. The quick reaction with water is part of why it reacts so quickly on your hands. Gorilla glue is similar, but is polyeurethane-based and reacts primarily with oxygen. Elmer's glue , as well as many other glues, works by evaporation. There is a solvent in the glue that slowly evaporates leaving behind a latex polymer. In this case the polymer was always there in the liquid glue, but the individual polymer molecules were being kept separate by the water . When it dries, the water leaves and the polymers tangle up on each other forming a solid.

If you killed someone on the Four Corners Monument, which state's laws would you be prosecuted with?
|
[Slightly NSFW.] Since it's a serious crime that is inter-state, the federal government will likely step in. Also, it's a national monument and in Indian Reservation territory, even more reason for it to be the FBI. Double also, simply searching Google about this brought up an ELI5 post about this as the top result.

how a boxer is crowned best pound for pound fighter, and how Pacquiao is considered higher "rank" than Mayweather?
|
It's basically a very subjective ranking system. Let's give ourselves Pacquiao vs Mayweather. Bear in mind that I'm not much of a boxing fan, I just know how it's measured. Anyway, Pacquiao has been against many others of his weight division with impressive w/l/d/ records. Their records are matched against each other, then the match quality is measured. For example, the Pacquiao/Hatton fight. He took down Hatton within the first few rounds solidly. That gives him more brownie points than say if he had a hard-fought, nail-biting match. It's essentially a measure of dominance in your matches, hence why it's subjective as to who does the rankings.

Why are modern computers still having trouble with editing large-ish (20-50MB) text files?
|
it is the limitations of the software not your computer. if you want to push 1000 balloons up a chimney they still need to go one at a time, more cores and ram = more chimneys. but if you have 100,000,000 balloons it will always bottleneck while the program tries to sort the next lot of data so the balloons appear in the correct order. also that is a HUGE text file. EDIT: other things may also be at play like memory leaks and cpu load before you even try.Software developer here. Most text editors do not expect you to be editing huge text files so they will load the entire document into memory and display it in it's entirety. When you get to a certain threshold Windows will not allow more physical ram to be allocated as since it will encroach on OS stability or RAM pages are being used by other processes which cannot be overwritten. So instead it will take what it can and put it into the applications working set memory and then it will take the rest and attempt to apply to the page file. This file is a binary file that works like an overflow for memory or for memory items that still have a valid pointer reference to an application object but have not been access for some time. Moving memory around like this allows the system to have as much access as possible to physical ram without using it all up. So your large text file be resident in physical ram and page file ram and its the page file that's slow. Some text editors will stream off the disk as you edit. However there are technical limitations to this so not many editors do it. Quite a few hex editors work in this way as users mostly edit single points in the file which is defined to be a certain size and so editing will not affect the overall structure of the file itself.

Why don't car companies like Ford and GM make technologically advanced replicas of some of the classics instead of ugly modern cars?
|
Remember what happened last time they tried that? The Chevy HHR and the PT Cruiser were created. Horrifying.they were incredibly unsafe shapes, impossible to make as safe as the newer ones without a complete redesign of the shape which would defy the point of remaking the old car also you overestimate how much people want old cars, they're kinda ugly as fuck

In reference to Phillip Hughes' accidental death, explain a vertebral artery dissection from such a relatively small object.
|
An arterial dissection is a tearing of the inner lining of an artery. Basically, an artery is composed of multiple layers of tissue. In a dissection, which can happen spontaneously or be caused by trauma, the innermost layer gets torn. Blood then gets underneath this torn layer and begins to push the two layers apart. This can cause the tear to travel further up the artery, but trouble arises when the amount of blood filling this new spaces can cause the torn inner layer to get pressed against the opposite wall of the artery, completely obstructing blood flow. With the blood flow obstructed, pressure begins to build up and the already damaged artery wall can rupture. I can't find any reference stating where exactly the dissection occurred in Phillip Hughes', however the vertebral arteries run all the way up the neck and join with the carotid arteries around the base of the skull. A rupture in that general vicinity would cause blood to pool around the brainstem. If you're not familiar with neural anatomy, the brainstem controls a lot of our autonomic functions , so the pooling blood around it will lead to a build-up of pressure that compresses parts of the brainstem, which in turn can result in rapid loss of consciousness and death. Edit: Found an [image] that might help clarify what I was describing.

Why does CO2 increase world temperature but a big enough Volcanic eruption lowers it?
|
CO2 acts like an invisible blanket, or more accurately like the glass in a greenhouse. It's a "greenhouse gas", which traps radiant heat close to the planet. A huge cloud of dust and smoke from a volcano isn't invisible. While it will also insulate, it's also quite reflective, bouncing sunlight back into space *before* it warms up the Earth. This is why debris clouds from volcanoes, huge meteorites, or hypothetically nuclear war, can caused a "nuclear winter".

Static Electricity and it’s connection to objects
|
It’s been a while since this lecture, so forgive me if I mess up a few points. From what I remember, every object on the planet has sort of a key number of electrons it likes to have. Objects that are known to be great conductors of electricity have a much higher key number than say humans do. So, whenever an object has a deficit of electrons, it takes all the electrons it can every time it makes contact with another object that has extra. They all have a tendency to want to remain at that key number. If something has an excess, they’ll give them away. If something has too little, they’ll take them.

Why does WinRAR never actually require payment?
|
From _URL_1_ > Winrar is licensed as "shareware", the license type is mostly outdated now, but back in the 90's you would see most software marketed as either freeware , shareware , or just plain paid software. These days we see more software released in the demo/full version form, although some software companies still release shareware > A lot of shareware was released like Winrar back in the day, where paying for the software was more of an option than a requirement. By not blocking the customer out after 30 days it garners the customers respect and the developer hopes that you'll eventually pay for it, even if you 've used it for a year or two. Even if you don't, you'll probably recommend it to a friend and your friend may become a paying customer. > It's basically writing software with the hope that enough customers will pay to make it worthwhile. Winrar probably sticks with this model simply because its worked for them for so long. It seems like they base it on honesty and trust. They trust that when you are fully satisfied with their service, and that it meets your requirements, that the customer will pay the fee Edit: a little funny I found while digging _URL_0_

you know how people do crazy stunts like unicycling through the Amazon for charity? How does that actually raise money?
|
Basically people just donate money because they either think the stunt is cool, or the stunt gets their attention and then they learn about the cause and donate because they think it's righteous. The stunt is about getting attention. Nothing more.

Why do people swap languages while talking?
|
i do this, switching languages after sentences/in the middle of a sentence/or whatever. the reason i do this is is because sometimes things just don't translate well. some words/phrases in another language or in English, just doesn't have an equivalent that will give you the full effect of what you're trying to say. and then there are other times when you just don't know how to say that word/phrase so you say it in another language instead. being fully fluent means that you can "think" in that language so sometimes, i just want to use that language insteadMaybe it gives them a little je ne sais quoi?', "I switch a lot between Dutch and English. In the Netherlands we're exposed to a lot of English, movies and series are subtitled instead of dubbed, at work there's a lot of English and of course on the internet it's dominant. Possibly as a result of that I've started to notice that a lot of times I feel a certain word or expression in English captures a lot better what I'm trying to say than anything in Dutch. At work it's the opposite, we try to speak English around non-Dutch coworkers but sometimes certain things are too hard to translate and I might switch to Dutch for a sentence or two to get my point across and let others provide explanation so the non-Dutch aren't left out.

If meds are always eliminated in half by the body, how is it ever completely eliminated?
|
First, the half life of a medicine is more of a general rule to follow when considering dosages, and it's not like **exactly** half is left after each half life. Also, unlike pure math, in the physical world an object can't be cut in half infinitely. Eventually you would get down to a single molecule and at the next half life, the medicine would be completely gone. Even if you continued cutting that single molecule in half , how many molecules of that substance do you have? Zero, because a broken molecule isn't the same substance. In general, after around 4-5 half lives, there isn't enough medicine to affect your body anyway.

How come my belly expands right after eating food, even though the food I've eaten won't have reached all the way down there yet?
|
Well your stomach when empty is fairly small and sits just below your rib cage. When you eat it fills with food and stretches out. It will displace some of your intestines to make room. That could be causing your stomach to stick out. Also when you eat food it opens up the floodgates downstream, if you know what I mean, so it may push some stuff from the small intestine to the large intestine, which is closer to the skin .

Why Do Reddit Points Fluctuate Over Time?
|
The fluctuations are a bot prevention mechanism. Shadow bans were created in order to get rid of malicious bots, but that could be easily tested if their upvote did not count toward a thread if the page was refreshed a minute later. Thus, Reddit came up with the idea that they should create vote fluctuations. The vote fluctuates up and down randomly to make it difficult for malicious bots to operate

A recent YSN post said that cell phone companies can't prevent me from unlocking my phone. What does that mean?
|
You're mixing up unlocking and rooting. Unlocking is taking off a restriction that prevents you from putting a SIM Card into your GSM phone. When the phone is unlocked, it will let you just take your phone to the other network and have it worked. To remove something like bloatware, you need to *root* your phone. Rooting isn't illegal, though it may void your carriers warranty. What rooting does is allow you to install custom software and remove carrier bloatware. If you have an Apple phone, the process is called *jailbreaking*. I am not sure if anything similar exists on Windows phones.

how does a mere bit of suncream/sunblock protect the skin from the suns rays?
|
Sunblock and sun cream contain very small particles of silver and zinc oxide which reflects the rays of light off rather than letting them hit your skin, the particles are fine and plenty enough so as long as you have a layer covering your skin, they will reflect most of the rays off, but some will still get through depending on its factor and how much you apply.

Why can't I hear myself snoring, or anything else for that matter, when I'm half-awake/half-asleep?
|
As you move from a waking state to a sleeping state, your senses get turned off. This last summer, I was running a box fan in my bedroom to stay cool. In addition to providing airflow, it also make a pleasant low drone. One night, I noticed my hearing turn off because I was listening to the fan's noise. I was startled and the change woke me up, turning my hearing back on. I say mostly turned off because there does seem to be some kind of watchdog that listens for unusual and important noises, such as your name being called and so on. But snoring falls into the "usual" category, so your brain blanks it out.

What is Obama Care?
|
Obama care refers to the Affordable care act, which changed a few things about American healthcare. The whole act was extremely long, and covered many aspects, which is why it took a long time to draft and pass and take effect, and is beyond the scope for a single Eli5 thread. Of significance , some key provisions protected those with existing conditions from being unable to find insurance at a reasonable rate, and guaranteeing certain individuals coverage without a extreme financial burden, and extending the maximum age that some younger individuals could stay under a parent's plan. A repeal without a new plan in place would impact many people, and could leave many without insurance when they need it most. Without the Act's provisions, companies could alter rates or drop coverage to individuals, who may no longer receive the subsidies that allowed them to have access to healthcare in the first place.

Why is riding an elephant deemed inhumane while riding a horse is not?
|
Horses are domesticated by humans for the purpose of cohabitation with humans. They have been selectively bred over thousands of years to be suited to a type of work, such as pulling a cart, carrying a rider, etc. Moreover the equipment used, and the veterinary knowledge of their body mechanics have been extensive studied and improved. Psychological changes, as well as physical changes, attend to the process of domestication. Domestic animals are not stressed by the company of humans and consider them part of their natural herd. As long as they are kept according to their needs , they are in their most natural state in company of humans. For humans have made them exactly what they are; mentally and physically unlike their wild forbears. An elephant is a wild animal, there has never been any domestication of elephants, only taming, and taming is not the same thing, there are no biological changes in the animal, it retains all of its wild instincts. Selective breeding for domestic traits has proved impossible in elephants. Tl;dr the difference between a dog and a wolf.

Why does air feel cooler when it's moving when energy/movement creates heat?
|
Our bodies are constantly radiating heat. Air, being a good insulator, forms a hot-bubble around us, like a blanket. When the wind blows, it brings cooler air against our skin and removes the air we've already heated. Also, you have to know that our skin doesn't sense temperature, but the relative flow of heat in or out of our body. As the cool wind blows, it saps energy from us, which feels cool.

Boxsprings. Is there an actual purpose to them?
|
Just asked this at the mattress store! Their only function is to keep the mattress flat so it wears more evenly. If you don't have a bed frame and leave your mattress on the floor you don't need one. If you have frame with a solid bottom that keeps your mattress flat, you don't need one. You only need them if your frame has plank supports, because the mattress is too soft to hold up its own shape for many years and will start to sing down in some places between the slats.

Why do different alcoholic drinks have different effects on a person?
|
There is a theory that this purely psychological. Sort of like the placebo effect . For example, we associate whisky with sadness so we expect it to make us sad/mournful drunk. Usually, that's what happens. EDIT: for clarity-- what I meant by "usually, that's what happens" is that because we expect to feel sad/mournful when we drink whisky… we make ourselves feel that way. Purely psychological.

How can Pi never repeat if it never ends?
|
What they mean with never repeating is that it won't act like normal fractions like 1/7 = 0.142857142857142857142857142857 which repeats the sequence 142857 forever over and over again. The same sequence "142857" occurs in pi too. Apparently it occurs 210 time in the first 2 million digits of pi. So you have lots of parts that get repeated in pi, but never anything that gets repeated endlessly. You can describe 1/7 by given the first couple of digits and then saying that the last six repeat endlessly. You can't have a simple description like that of numbers like pi. If you look long enough you will find every possible sequence you might look for in pi, including an ASCII representation of the collected works of ShakespeareIt doesn't mean that it contains no repetitions whatsoever, it means that it's not a repeating decimal. For example, 1/7 = 0.142857142857142857 is a repeating decimal because the "142857" part repeats over and over. Pi is an irrational number. One property of irrational numbers is that they when written as decimal fractions, they form a non-repeating decimal.

What is the difference between pirating a game/movie and buying a used copy? Why are "re-sales" legal but pirating isn't?
|
> why publishers and developers aren't pushing to end used sales. They are, but it's a delicate issue, just ask Microsoft's PR department. The concept of the first-sale doctrine in copyright law dictates that once the holder of a copyright has sold on a good to a consumer, that consumer has the right to pass on the good to whomever they see fit. They can't legally reproduce it but they can sell their purchased copy. This law was written in 1976 and so there are issues when it's applied to digital media which lacks the degradation characteristics of a physical good. Points in favor of used sales: * Many gamer's look at used sales as a way to subsidize the price of games. It costs $60, but they'll sell it back for $20 so the net price is $40. This increases initial sales of some titles at launch.* Lower prices of used games can encourage some gamer's to try titles they might not have otherwise purchased, and if they enjoy the game, they might be more likely to purchase a sequel upon release.* It is the correct option under the letter of the law if the copyright owners are selling a copy of the good. Points against used sales: * Used sales shift money away from the developers who created the game and towards the middleman. The less money developers have the less they can spend on development of new games.* The range of genre's available to consumers is narrowed because publishers force development teams to focus on features, like multiplayer, they hope will delay gamers from selling the games back to stores. * First sale doesn't technically apply if the purchasers is buying a license to view the content, not the content itself. This is a squishy argument, but the legal justification for forbidding sales of software. TL/DR Part1: Copyright law protects used sales, not unlicensed reproduction TL/DR Part2: Used sales have benefits and detriments to the game industry

How come I can focus my eyes on the floaters on my cornea, but not my finger when it's almost touching it?

Your eye isn't really focusing on the floater, as it's behind the cornea. It's more like having dust on the film, it gets sent directly to the brain as is. Your finger you actually do need to focus on.

How does Global Blue make money?
|
> Global Blue operates a wide and trusted Tax Free Shopping network, allowing travellers to save money on purchases they make in any one of our 270,000 partner stores around the world Above description if from their website. You only get tax refunded if you shop in one of their partner stores. Think of it as a discount membership card, where you shop in the partner stores and get discount. But here they refund you the taxes instead of giving any discount. When you shop from their partner stores, you bring business to them, more business you bring to them, more will be the commission earned by Global Blue. This is how Global Blue earn money. And from that money they refund you the taxes. Moreover, I am pretty sure that those stores get some tax benefits from their local governments to bring in the foreign currency.

In the course of history, why have people exiled others as opposed to killing them?
|
If Napoleon was killed, it would have made a great deal of french people angry that their leader was killed, and turn him into a symbol another french army could rally around. "Our leader was killed, let's avenge him!" Instead, by exiling him, no one is angry that he's killed, and it's hard to rally around a leader when he's just sitting around growing old. There's no symbol or cause for people to rally to. --- In general, there are many different reasons why people are exiled instead of being executed, but avoiding making martyrs is usually a big factor.A lot of times, a leader goes into exile to save his own ass. The government of another country will offer him protection and sanctuary. The government also promises not to extradite the leader back to his home country to face trial/execution. In the case of Idi Amin of Uganda, he was offered protection by Muammar Gaddafi of Libya. He lived in Libya for about a year. He later settled in Saudi Arabia, where the Saudi royal family allowed him sanctuary and paid him a generous subsidy in return for his staying out of politics. Here's a list of other [exiled heads of state].

The practical everyday uses we gain from the American high school courses English, Math, Science, and history.
|
Adding a quick note to the good material already here: One major problem for many students in school is they firmly believe they already know enough of these subjects to function well in society. And if they do not they think they can get the info quickly via google or other means. We all believe we know enough at those ages. But once you are out of high school you soon discover the real power of knowledge and communication. The skills used to navigate life in your teens does not map well onto the skills needed in your later years. If you develop very solid skill sets early on, when it is relatively easy to learn them, you will be a lot more capable in managing what life throws at you. Being adaptable, a good critical thinker, a good reader/writer, being someone who has a good grasp on how the natural world works on a basic level, and basically a good generalist can take you a long way.English allows you to communicate your thoughts and ideas clearly. While it might be easy to dismiss correct spelling as unnecessary, it makes it a lot easier for others to understand you, especially when their own English might not be so good . It's quite difficult to shop without math. For more advanced math, think about your tax returns, working out a budget, your paycheck, etc. For science, it gives us an understanding of the world around us. Perhaps more importantly, it gives us an understanding of the fundamentals of science itself--thinking critically, testing hypothesis, etc. History is important because understanding your own history can help avoid mistakes. You can see patterns over time, and how they came to be. History can explain the dangers of war, what happens when disease outbreaks happen, etc.English: how to construct an argument and engage in thoughtful discussion Math: How to solve problems analytically and logically Science: Using the skills of mathematics and applying them to real world situations History: Learning about the past to make informed decisions about the future, especially politically.

Why do we bite our teeths together when we doing something exhausting? (Like when you're in the gym and doing a hard workout)
|
I'm not sure there is an exact known answer but the theory is: to make it easier on your brain. Tensing muscles together takes less effort for your brain than trying to keep multiple muscles doing different things. Kind of like the old trick of patting your head and rubbing your stomach, your mind will eventually cause both actions to mimic each other. It's also easier for your brain to know that the jaw is clenched than try to keep track of the exact position of your jaw.

Why do radio stations announce the next songs and then play them in the reverse order?
|
They announce the most popular songs first so that it grabs your attention and more people keep listening for that song to play, then go to commercial then play them in reverse order so you wait for your song to come up. The radio world is all about getting you to listen just a little bit longer. edit: Added aside, they almost always say the name of the artist BEFORE it plays and then the name of the song after; this is so that if you're hoping to hear a new song from X artist, you won't flip channels when you know it's the same damn song you've heard 12 times today already.

What are the most noticeable differences between genuine American-made Fender Stratocasters and Gibson Les Pauls, compared to cheaper counterparts like Epiphone or Squier made in Indonesia, Mexico, etc.?
|
For current guitars, the Made In USA badge adds a lot to the cost, but it's hard to generalise beyond the obvious factors: differences in quality of wood and parts. Historically, it's been a moving target: for example, I heard only good things about first Squiers made in Japan, some arguing that the quality exceeded that of early Fenders. I think this is *generally* true - today's cheap guitars have more consistent quality compared to 1950s models. ) ).

What makes someone professionally good at fishing?
|
Probably experience and perception. I'm sure a good fisherman can tell where the fish will likely be in the lake, or how deep to go to get certain fish and what patterns they follow", 'A big portion of professional fishing is simply dedicating plenty of time to the sport and attending events. Nobody can make the fish bite and pros will be unlucky somedays. Statistically attending several events a month will earn you a few big wins over the season. Fishing is also a very political sport involving who you know in the upper-divisions and having the money to cover airfare and other expenses Fishing is a sport where once you 've "made it" you are pretty set in the sport. Often times this includes sponsorships to cover every type of equipment you can imagine and waived entry fees from past qualifications/notoriety. This sport also has the benefit of being low-injury so aged players in the industry still remain competitive.

What makes lithium ion batteries so combustible?
|
Lots of chemical energy separated by super thin insulators made of an easy to melt plastic. The fire produced in a tiny spot heats the insulator enough to melt it in the adjacent area, which generates more heat, . It's a chain reaction.Chemical batteries rely on a chemical process called a redox reaction. "Redox" is a contracted form of "**Red**uction/**Ox**idation." Without going too far into the chemistry and physics of how and why redox reactions occur, it has to do mainly with moving electrons from one source to another. A really good battery has 2 main parts, a reducing agent and an oxidizing agent. The bigger the gap in reaction energy between the two, the more power you get. You might recall that combustion is a form of oxidation; so when a battery is breached or used incorrectly, the oxidation reaction that's normally happening in a controlled manner in the battery can get out of control and create those fun [fireball videos.]', "All commercial lithium-ion batteries use organic electrolytes, i.e. they're composed of carbon, hydrogen, and oxygen, so they're highly combustible. Internal short circuits in the battery between the positive and negative electrodes, which can happen for a number of different reasons , can create sudden temperature spikes inside the battery. As the temperature rises, the pressure inside also rises, and this can eventually cause the battery casing to fail. The superheated combustible electrolyte begins venting, which ignites in contact with air. Source: my master's thesis in college involved thermal safety for lithium-ion batteries.

After a terror attack, why do certain groups claim responsibility?
|
So, a lot of terrorist groups have some kind of agenda, normally they think that there is something wrong with a group of people, and they are the enlightened few who will "purge the world". If we look at them like ransomers, they have a set of demands so all they need is a hostage. When there is a terror attack and a group claims responsibility for it, that victim population works kind of like their hostage. So basically claiming responsibility is their way of saying, "This is what we are capable of, pay attention/ give in to our agenda or we will do more."

How exactly is money transferred to athletes and celebrities when they sign those 1+ million dollar deals? Do they write cheques? Or email transfer 6 million dollars?
|
Pretty sure they just get checks like anyone else would. Last year Thomas Vanek got investigated by the NHL because he was gambling and signed over one of his paychecks to cover a bet to his bookie. He ended up being clear of any wrong doing but how stupid do you have to be to sign over a paycheck to a bookie.There is a great story about Donald Trump and Mike Tyson . Tyson did a fight in New York that Trump had hired him for. The pay was something like ten million dollars for Tyson. After the fight Trump gave Tyson the check which Tyson tucked into the breast pocket of his tux. Six months later Trump's accountant knocks on the door of his office. The ten million dollar cheque had never been cashed and just went stale dated . The accountant asked why Tyson hadn't deposited the cheque. Trump called Tyson and asked what was up. Tyson had forgotten about the cheque and it was still in the breast pocket of his tux. Life is weird.

Why does it seem like there are way more conspiracy theorists in the USA now than 20 years ago?
|
Probably has a lot to do with the fact far more people have gotten on the internet in the past 10 years. Sure, internet wasn't rare in 2004 but more people than you might imagine weren't really using it until the last ~5 years. Additionally people tend to group up so that you'll get concentrations of people likely to be conspiracy theorists. Things like Bush getting elected with < 50% of the popular vote, the whole 9/11 and related invasions, wikileaks and of course recent releases around the NSA have given a whole lot of fertile ground for paranoia and distrust.

Unsupervised Learning/Machine Learning and how data is relevant
|
Unsupervised learning isn't generally used to make predictions - for that task a supervised learner is typically used. You hinted at why in your question - if we *do* have a way to evaluate whether our predictions are accurate, then we should be able to frame the task as a classification problem and train a supervised learner to make predictions. Unsupervised learning is used when we don't have a way to separate old instances into labeled "classes" that we care about predicting for new instances. Depending on what model you use, an unsupervised learner might find groups of students who are similar in some way, or it might find which feature values are linked together in some predictable way, or it might point out students that are abnormal with respect to the general population. Sometimes you can go in after-the-fact and see that your unsupervised learner has separated students into groups that you can make sense of, or that you can tell why anomalous students are anomalous. But that's not guaranteed. & nbsp; If you have *some* labeled data but not much , you could run an unsupervised learner on all the students and see if those labeled students fall in a single cluster, but there's no guarantee. A more popular approach here is probably *semi-supervised* learning, which uses unsupervised techniques along with some labeled data to build a predictive model.

Why should you not stir long-grained rice (such as basmati) when cooking, but should stir short-grain rice (like sushi or risotto rice)?
|
Simply put: 1 - Some types of grain break more easily than others, keep overcooking after the fire is off and/or are covered in the gran flour that makes it sticky and even a paste sometimes. Which takes me to point 2; 2 - That's the way that specific receipt is cooked, whether is because make more sense for the type of grain and the result you want to achieve, or because it's the traditional way of cooking that rice in its country of origin. In Spain we use short fat gran and is neither stirred nor moved around when cooked.

Why do we sometimes get fleeting pains at random parts of our body?
|
The phenomenon is called "referred pain". It occurs when sensory information comes to the spinal cord as coming from one location, but is interpreted by the brain as coming from another location. Source: Gray's Anatomy for Students, 2nd edition. Page 76 under "In the clinic". Edit: Btw I'm disappointed by all the shitposts in this thread. Edit 2: /u/ionizedreactor gave some plausible alternatives as wellSometimes its a momentary cramp which can be because of dehydration or water retention. Other times it may be a spasm from nerves randomly firing. You could be pinching a nerve or something is not resting well. Or you could be dying some diarrhea death soon"Stress - Your muscles get tense and cause pain. Chronic stress can cause ulcers in the stomach. Ulcers will make your stomach hurt." Wrong. Stress does not cause ulcers. Ulcers are caused by Helicobacter pylori. Google it.In addition to what's been written, I'll throw out a couple of other things I haven't seen yet. Two common skin bacteria, group A strep and staph aureus, secrete exotoxins that cause burning sensations. If these happened to get into a microabrasion, they could cause a seemingly random burning or stinging sensation without a visible cause. Certain immune cells can also degranulate, which means to release small packets of noxious chemicals, when they come in contact with triggers that can cause a similar sensation as mentioned above. Some diseases sensitize nerves so that they respond to normal sensations as if they're painful, and sometimes things which can cause pain, like ovulation, will do so at random, either at the site of the organ, or referred to odd places like your shoulder, as another poster mentioned. Lastly, there are things, like gas, which you don't think of as being arbitrarily severely painful which can be, given the right set of circumstances, and that can pinch at odd spots in the abdomen, or even put pressure upwards against the diaphragm, and once again, refer up into the shoulders through the phrenic nerves.

What causes the involuntary scowl when we eat something unexpectedly bitter?
|
I think it was Steven Pinker who said that it's probably an evolutionary defense mechanism. When you taste something unexpectedly bitter you tend to make a face and stick your tongue out . This is probably a mechanism to eject any of the substance still in your mouth. Not really any evidence though so it's just conjecture.
|
If I, for example, pop a zit on my left shoulder, why do I sometimes feel a sharp sting in my lower back?
|
I would guess nerve endings. My SO at the time poked me in my belly button one time and I felt a sharp pain in my anus area. No jokeI thought I was the only one! when I scratch a part of my body sometimes I feel a sharp sting on another random part of my body too.

What's the story behind the Enron scandal?
|
It's a very complicated situation - I've only watched the documentary *Smartest Guys in the Room*. Long story short, the leading executives made a lot of moves that put a lot of money in their pockets at the expense of their company, and the livelihood of thousands of employees", 'They were caught using fraudulent accounting practices. Executives were involved in securities fraud and insider trading. Company was forced into bankruptcy. They were later shown to be involved with just general shady business practices, the most notorious being exploiting energy deregulation and stability issues in California

how hard would it be for someone to go off the grid
|
If nobody is looking for you, its not hard. The hard part is staying off the grid. You need to be able to sustain yourself long-term, and needing a trip to a hospital if you start vomiting blood could mean an end to the whole thing. But if you are wanted by the police in any serious way, the odds of managing to stay free aren't great. If you were in the military, they have your finger prints on file. And if a cop detains you ever, you can refuse to say who you are, but those fingerprints will eventually give you up.

Why are some TV shows recorded in front of a live studio audience?
|
First off those type of shows are called Multi Camera Setups. And they play out more or less live like any other performance, they don't have to record one actor, then the other, then back and forth like single camera shows. Those are done on closed sets and are considered higher production value because there is more room for directing, multiple takes, and cinematography. They are really like plays and have an audience as a throwback to the days when it was done that way for lack of knowing how to do different. Television was live, variety and talk shows and the stage which is suited for this and might as well have an audience.They get money from the people watching and they get natural laughter.

What is that grainy stuff around resized low resolution pictures?
|
It's impossible to truly scale up an image. You can't just stretch things; the computer needs to know what pixels are going where. There's typically an interpolation algorithm that tries to guess where the pixels should be when scaling, but there are limits to how accurate it is. Mistakes are made and you can get an end result like that. You need an interpolation algorithm or the pixel ratio just increases. Without the algorithm, if you were to scale up a picture by a factor of three in height and width, every pixel just becomes 9 pixel square and everything would look blocky. tl;dr: the computer can't just stretch an image. It has to guess where it thinks everything should go and it makes mistakes if the scaling is too big. It wasn't very ELI5, but there's your answer.

What happens when one of the wings of an airplane break off?
|
The plane is faced with an option: either generate lift with the remaining wing and face a massive rolling force, or don't generate lift and fall out of the sky. In either case the plane likely crashes. One thing the pilot could attempt is to roll the plane 90 degrees to have the remaining wing pointing up or down, then use the rudder to angle the nose up. If the plane is light enough and has enough thrust then they can generate some lift from the tail and some from their engines pushing down. They can also get a little bit if lift from the body of the plane being angled up. Most planes would be hopeless in a detached wing scenario. I've seen the above maneiver performed in video using a model RC aircraft, but it would be impossible in a passenger jet.

Why would Assad’s regime use chemical weapons, as opposed to conventional ones, which don't generate anywhere near the same international uproar and are presumably equally lethal, albeit less horrifically so?
|
Every town exists for a reason. Some enterprise is producing something of value to someone outside the borders of the community, bringing in cash to support the town's local economy. If you flatten the town, your country loses it's largest producer of widgets. Generations of experience, tools and machinery evaporated. You still need widgets, but now someone has to kick out millions to rebuild the factory and the town around it to produce them within the country again, and even then it'll be a year before you're in production. Until you're producing again you'll have to pay double the price for imported widgets, which is made even more complicated when the US has [1000ft of freedom] parked off your coast, enforcing a trade embargo. However, if you hit them with chemical weapons the property damage is trivial. Sure you lose the people, but they were lost anyway. With them out of the way more cooperative people can be shipped in and widget production can begin as soon as they figure out where the light switches are. For experience, you can recruit cash-motivated foreigners like fabrication-mercenaries to train the new folks.> presumably equally lethal This is pretty much why. Chemical weapons tend to have very high human casualties while being able to minimise damage to infrastructure. To achieve the same effect with conventional armaments you would incur far greater collateral damages in terms of infrastructure.Why would Assad, who is currently winning with the help of Russia, carry out a chemical attack knowing it will harm even more of his image and risk destroying Russain support? It makes no logical sense so there is something deeper going on with the attack. Assad is in no way clean, nor do I support him but during times of war, you can't trust anything you hear, see or read in the media. The conflict in Syria is far more a complex issue than what it appears to be. EDIT: look at it from an objective point of view, who would benefit most from such an attack? Sure as hell aint Assad.

What is an IPO and at what point do you have one?
|
An IPO is an Initial Public Offering for a company's stock. It's when a company starts selling their stock on a stock exchange like the New York Stock Exchange or NASDAQ. The reason for one is to take on more investment capital, and also to allow the initial investors and company founders take their investment off the table. A company might take on a few million in investment from venture capital firms, but to really fuel expansion they might need hundreds of millions and can gain this through an IPO. Additionally, the VC firms typically want to see a return on their investment in 3-5 years, so that often means an IPO or acquisition. Also, the company's founders and early employees have tons of net worth tied into the company that can't easily be spent so an IPO allows them to cash out some of their stakes and have money to buy houses, cars, diversify their investment portfolio. Companies can IPO sooner now than they used to decades ago, but they can't do so initially upon conception. There isn't enough of a track record to attract non-professional investors and the costs/requirements for government filings, earnings reporting, etc. would be to steep for a small start-up. Without some sort of early investment from angel investors, venture capital and the like there wouldn't be enough of a product to make the company viable enough to go public.

Why am I able to tilt my head back and pour a drink down my mouth without it immediately traveling down into my body? Shouldn't it automatically slide down my esophagus?
|
You have a set of sphincter muscles in your throat which manually pushes food down, this is what allows you to eat and drink when upside down, or in a zero gravity environment, It's also why you have to swallow food, instead of letting it slide down your throat. You'd end up choking every time you tried to eat or drink if you didn't have them.

Why do humans live to be so old, but animals like dogs only live a few decades at most?
|
The short answer is that no one knows for certain. The most probable reason is the evolutionary strategy our species has, while some other animals focus on having lots and lots of offspring with the hope that at least some will survive humans have comparatively few but we spend more time nurturing and protecting them to ensure that they have the best chance of survival. Our intelligence and capacity for emotional ties may also help, grandparents are often as protective and caring of their grandchildren as parents are of their children; the more parents and grandparents available to help raise the child the better its odd of survival. It's evolutionarily beneficial for you to live long enough to protect and care for your grandchildren for them in turn to pass on yours and their genes.

Why do so many gaming web sites demand to know your date of birth (with annoying drop-down menus), but porn sites never do?
|
Porn websites can't be blamed for school shootings, so gaming websites have more reason to cover their asses.Porn sites are doing the minimum it takes for legal compliance. The game industry, OTOH, holds themselves to higher standards. The ESRB requires more stringent restrictions on mature contentProbably because everything on a porn site is assumed to be 18+, while game sites might show both the latest Pokemon and the latest GTA on the front page at the same timeNothing shouts "School shooter!" like a quick round of Peggle.

How come the adverse effects on the leaflet of every drug include almost any possible effect you might think of?
|
If you tracked all of your high school classmates for 5 years, would some of them get into car accidents? get killed? get cancer? Odds are pretty good of that. Did that occur because of life happens? Or was that because they all attended the same high school? In a large scale drug study, same thing occurs, people get all kinds of side effects, some might be coincidence, some might be drug related, some might be a mixture of lifestyle, genetics, disease and the medication. So drug companies have to report that in their study, these side effects occurred. This way they've done the reporting of what the study discovered, then it's up to you as the patient and your doctor to determine if those risks are acceptable to you.

Neoliberals are open border capitalist, which breaks from traditional positions liberals held as this favors corporations over labor. Labor used to be the bread and butter of liberal policyNeoliberal means that you are generally in favor of their being minimal government interference within the economy. Particularly with regards to international/global trade.

Why does reinstalling a program fix problems that it had Before?
|
Because reinstalling overwrites certain parts of a program. It fixes problems cause by file/registry corruption, and update errors. When you reinstall a program, registry entries are made for the new install, and new versions of the program's files are installed into the program directory. Finally, if there was a bad update, this will effectively revert to another version. The biggest example of this is reinstalling the OS, but it works with any program for the same reasons. It does not repair user or procedurally generated files that do not exist as part of the base install nor does it fix problems not directly caused by the files and registry entries overwritten.

How does eviction work?
|
varies from place to place, in NY it takes a court order from a judge before the police can evict you. It is a long, expensive and tedious process.That should all be formally laid out in your lease. That's why everyone should read leases *very carefully* before signing. It varies from state to state and landlord to landlord. But if you pay up before the eviction date, I think you're fine.

How dose bacteria stay alive in places like my shower curtain or in my wash rag, where dose it get its nutrition from?
|
The bacteria in your shower curtain is actually living on the soap scum which includes oils for its nourishment. The wash rag offers even more diverse fare-- some soap as well as skin particles or food particles if a dish rag and the fiber material of the rag itself. Single celled organisms don't require very large amounts of food to sustain them, so either of these "habitats" can support hundreds of thousands of bacteria per square inch.

Why does England have so many different dialects of English but America doesn't have as much even though its a much bigger country
|
According to [this Wikipedia article], England has 27 accents, and the United States has 40 accents . So it looks like your assumption is mistake, and the US has more accents than England. However, if you substitute "UK" for "England" you end up with 50 for the UK, putting it slightly ahead of the US.I'm not sure I agree with your premise-- how much have you traveled around the US? Texas itself has six or 8 different regional dialects, and that's one state

What exactly happens when a music producer "masters" a song/album?
|
When most people hear the term 'mastering', they are think of the mixing process, aka balancing volumes and adding effects, etc. Mastering is actually a specialized subset of mixing that is a form of audio quality control or quality assurance. Only a relative handful of people and studios are capable of mastering, compared to the thousands of mix studios out there. The goal of mastering is to get every track sounding as good as possible across multiple systems, meaning that the end product should sound great through your car, stereo, headphones and laptop speakers. Along with this, many artists' songs are recorded and mixed in multiple locations, and it's the mastering engineer's job to get them to sound like they all are polished to the same standard. Lastly, mastering produces the final CD or vinyl format for distribution and archives the tracks for the publishing company.

What is the idea behind being able to post bail for short term freedom before a trial?
|
Getting arrested with a crime is just an *accusation*. You are not a criminal until you're actually convinced in court. Since you're not a criminal, there's not reason to hold you in jail as *punishment*. The only logical argument for keeping somebody in jail is to ensure that they don't try to escape justice. To ensure people stick around and actually show up, people are asked to put down a "security deposit". Bail is this deposit. The amount of bail required depends on a number of factors but the idea is to set it at an appropriate level to make sure the accused shows up at trial. and if you think this is the only way our legal system gives advantages to those with more money, you're going to be really disappointed when you hear about the workloads that public defenders are saddled with.Being released on bail is conditional. If you break these conditions , you lose that money. I you keep them, you get it back. If you're broke and get busted for shoplifting you might get a $500 bail. You're probably gonna keep your nose clean til the court date because you had to get your mom to cash in a life insurance policy to post the bail money, and she's gonna whip your ass if she doesn't get it back. Now I you get arrested for say, being suspected of murdering a bunch of kids, or you're super rich and have the ways and means to leave the country, then your bail will probably be a lot higher or they may not even give you the option. TL:DR Basically bail is a way for the cops to not have to keep you in jail, but to give you a monetary incentive to show up for the trial.

How can a football team take a knee and end the game with a minute left (like in the Panthers v. Falcons game that just ended)?
|
He took two knees. The team with the ball is given 30 seconds to start a play, otherwise they face a "delay of game" penalty. Taking a knee is the same outcome as a running play or pass play that ends in a tackle without getting out of bounds. The play is over but the game clock keeps going and the play clock resets to 30. So at 1:00, they take a knee, wait until the game clock hits 30 and take another knee. The game clock will reach 0 at or before the same time that the play clock reaches 0 so there's no need to wait around for the game clock to run down to 0. The guys just say "good game" and head off the field during the last 30 seconds.In the NFL, the clock only stops in the event of an incomplete pass, the player goes out of bounds, or there's a change of possession . When the QB takes a knee, they are running a play, so the winds, and they have 40 seconds to run the next play. Since it was first and 10 and the panthers didn't have any timeouts, the falcons probably did run that last knee play, but they didn't bother showing it, and instead were focused on highlights and players reactions.

Why isn't it light out when it's night time? With all the trillions of stars blanketing the night sky, where does all that light hitting earth go?
|
There are large dust clouds within the milky way galaxy which block light from many of the stars. Apart from that, though there are many stars, they are also very far away. It used to be considered a paradox that, if there were an infinite number of stars, why wasn't the sky bright due to being filled with them. The square-cube law says that the sky should be brighter even due to very distant stars, assuming they're evenly distributed. The answer turns out to be that the stars are clustered into groupings of ever increasing size: galaxies, galaxy clusters, super-clusters,

How is it that when you blow air out of your nose, you can still smell the scent you are trying to avoid by blowing air out of your nose?
|
Because the same air is coming out of your lungs and back out of your nose. Like asking why you taste food when throwing up.When you smell something, it's actually just tiny particles of whatever it is in your nose. So blowing air out wouldn't necessarily get these particles out.
|
Does wind effect soundwaves?
|
Sound waves are vibrations in air like ripples on water Wind is the bulk movement of air like currents in water. If you were trying to signal to someone across a river you could drop a stone in the water by the bank you stand on, and hope they see or feel the ripples that reach the other side. If there is a strong current in the river it would carry the ripples downstream. Yes, wind can also blow away sound. ---- Sometimes a current of water hits an obstruction, collides with another current or is just turbulent because fluids do that kind of thing. When this happens ripples can be created that get mixed up with your ripples. Yes, wind makes noise that mixes with other sounds and obscures them.

Why are video games still sold as CDs while USB drives can be so much smaller, more durable and hold so much more.
|
A disc costs considerably less to make than a USB drive. Digital media will usurp discs, not USB drives.Manufacturers have moved to using DVDs, since they hold more, but not to USB, because it costs much more. For example, you can buy 10x 4GB USB sticks for $24.69 on [Amazon]. You can buy 100x 4.7GB DVDs for $36.99 on [Amazon]. Companies aren't going to pay nearly 10x as much for USB drives.

Why do firefighters "make it rain" on a fire instead of pointing the hose at the ground or directly into the fire?
|
What they are trying to do is prevent the area immediately next to where the fire is from catching fire. By doing this the fire will have nowhere to go and eventually use up the fuel that is currently on fire and extinguish itself. The "make it rain" approach is common because it starves the fire of both heat and oxygen ', "For a fire, you need * fuel* oxygen* heat **To extinguish a fire, you need to take away at least one of these.** With a burning structure like a house, you can't take away the fuel, and taking away the air is even less possible. That leaves the heat. That is exactly why you use water to extinguish fires: water is *great* at absorbing heat; in fact, there are very few subtances which can absorb more heat, and turning water into steam absorbes even *more* heat! But heat absorption happens only at the surface of the water, so a massive jet of water isn't ideal for the purpose because its surface is relatively small, and the water will just drain away before it has absorbed much heat. That's why you ideally spray the water into a fine mist of small droplets: it maximizes the surface so that the water can absorb as much of the fire's heat as possible, cooling it down to the point where the fuel can't ignite. **Note:** the above is slightly misleading in that the actual fuel of an ongoing house fire is not the solid structure but the combustible fumes emanating from it due to the fire's own heat. The water mist won't cool down the solid structure all that much, but it will cool down the fumes so they can't ignite, which takes away the source of heat and allows the solids to cool down until they don't produce fumes anymore.

What is exposure in photography?
|
Exposure is the chosen combination of iso, aperture and shutter speed to take a picture. This means that there's no such thing as an objectively good exposure. These variables have more effects than only lighting though, but we'll ignore that for now. For snapshots of general shots of city skylines, panorama's you want to have a balanced exposure, meaning you'd set the three variables to a level that doesn't overexpose or underexpose . For more creative effects such as shooting a silhouette of someone you might want to deliberately lose details in the shadows, so underexpose, for other effects you might want to deliberately overexpose.

why does the radar on big boats spin?
|
A radar not omni-directional. Just like a satellite TV dish it must be pointed in the direction of the signal in order to receive it. So in order for the ship to know what's going on around it it has to point in all directions. It spins 360° and scans all the signals around it.

How can the oscars preview something that will be on after a commercial when it is a live show?
|
Just because it is a live show doesn't mean each segment isn't meticulously planned weeks in advance. The show's producers know well in advance which segments are coming up and what is scheduled to happen in those segments, so they can create previews to highlight those segments.There is always a delay of at least 5 minutes. Radio, for example, has a 3-5 second delay which is why they tell people to turn down the radio when you're on a cell phone speaking on air. TV also has "teasers" which are filmed ahead of time and played to preview a future event.

why do younger people start off enjoying very sweet food, but as we age, very bitter, tangy foods become more preferable?
|
Your tastebuds naturally change over time, along with a bunch of other things which determine what's better or worse. When you're growing you need more vitamins, minerals, and more importantly glucose to power your body and it's growth. So things like sugar are more attractive. As well, kids don't go "sugar makes me feel bad if I eat too much" or "this is going right to my thighs" when they eat sugar, a sensible adult, however, does. So you get a type of psychological aversion from sweets and certain foods due to their nutritional content. Finally, another commenter touched on it, there's a normal flora in your intestines and stomach. This is a sum of a load of different bacteria . They help with digestion, killing bad bacteria, and a bunch of other things, but the thing that's important in this case is that certain bacteria thrive in certain environments. Some bacteria may REALLY like cauliflower, because they can break it down and it gives them a bunch of energy, so in turn they secrete chemicals which tells your body to eat more cauliflower. Thus by eating different foods, you'll program your body and normal flora to prefer those foods, and in turn those foods will become more pleasurable.Taste buds numb over time. You'll notice grandma salts the shit out of her food. Kids' tastebuds are over sensitive so acidic and spicy foods are like loud music for their tongues.

What is Fibromyalgia and why can it hurt so bad?
|
" Fibromyalgia is a common syndrome in which a person has long-term, body-wide pain and tenderness in the joints, muscles, tendons, and other soft tissues. Fibromyalgia has also been linked to fatigue, sleep problems, headaches, depression, and anxiety. " Yes I know a copy/paste. Basically your nerves are WAY too sensitive, and it just makes you fucking HURT all the time, really bad, no matter what. The slightest touch can feel like you just got punched in the balls. Both my brother, and my mother have it, and i 've seen the reprecussions it has. I'm probably due for it eventually. My brother takes lots of pills, mainly relaxers, to just make him..calm down. If he forgets it, he just simply can't do anything, he's just in far too much pain. My mother takes way too many pills, relaxers and pain relievers, and sometimes, that doesn't even help!

Are honeybees in danger? If so, how much danger are they in, and why should I care?
|
Yes. A *lot*, they're dying off at a rate of around 33% per year and we can't figure out how to stop it or even fully what's causing it. You should care because bees don't just make delicious honey, they also act as pollinators for pretty much every fruit and vegetable you enjoy eating. If they disappear out of the web, then so do much more central things like *corn*.

Why nails grow faster at summer when you are at sea
|
An explanation that was once given to me is that your nails are just being cleaned more often. Any dirt that may be accumulated under your nails is removed by being in the water so often, giving the whites of the nails a longer appearance.They don't. You are experiencing [confirmation bias]. Your nails are growing at the same rate as always, you just are less busy and have more time to notice them.

Why doesn't the US Constitution grant rights to everyone in the country instead of just Citizens?
|
Because they didn't want to give those rights to non-citizens, because then people could just walk across the border and demand things without having to be born here or go through a process to make them american. > Also why can the NSA spy on non-citizens outside the US? Because everyone does it, and no one really wants to do anything to stop it.

How can our relatively tiny eyeballs simultaneously absorb all the photons bouncing off something as large as the moon so that we can see it as a whole?
|
They're not. If *your* eyes were absorbing *all* the photons bouncing off the moon, nobody else would be able to see it plus your eyes would probably boil. Your eyes detect the minuscule proportion of photons that reach your pupils, and no more than that. Visible things scatter reflected and retracted light in lots of directions. Luminous things emit light in lots of directions. Only a fraction of those need to get to your eyeballs for you to be able to discern something.The lenses of our eyes concentrate visible light to the back of our retinas where the signal may be transduced into a meaningful image. Think about a magnifying glass concentrating the sun’s radiation onto a leaf to burn a hole into itThink about how a projector takes a small piece of film and expands it to fit a wide screen. The lenses in our eyes essentially to the opposite of this: they take a wide array of photons and concentrate them on the retina. From there, signals travel down the optic nerves and are sorted by the brain based on certain features, and then reintegrated into a meaningful image.

The difference between my voice and my recorded voice.
|
Your own voice resonates in your skull, which makes it sound a little lower and deeper. Think of it like singing in a big concert hall, where your voice echoes off the walls and creates a fuller sound. The sound of your voice literally echoes through your skull, but the echoes are so fast your brain doesn't sort them as separate sounds, they get incorporated into what is perceived as the single sound of your voice. With a recording, you don't get any of that.

Why cruise ships don't tip over when being knocked around in the ocean?
|
The height of the ship above the waterline doesn't matter very much. More windage contributes to listing but not a great deal in a ship that size. As boats get bigger, they get more stable exponentially. I'd have to look it up but istr in general displacement increases as the cube of size, and stability increases as the ^4. So if we take a given boat, and construct another one twice as big, its displacement will be 8x the original and its stability will be 16x. In the case of something as big as a cruise ship, as long as it remains watertight and afloat, it is not going to capsize no matter what the sea is doing. That doesn't mean its motion is always comfortable for passengers though which is why they do everything possible to keep rolling to a minimum including the foils carbonated_turtle mentions. Those do not contribute to ultimate stability, they will not keep a boat from capsizing, but they do dampen motion. Edit: math", 'Partially because of their massive size, but also thanks to the stabilizer fins pictured here, which help counteract the effects of waves and wind on the ship. _URL_0_

Why is it illegal in Kentucky to carry an ice cream cone in your back pocket?
|
_URL_0_ Apparently people used to stuff food into their back pockets to get horses to follow them. That way if they were caught they'd have an excuse that looked like they weren't actively trying to lead the horse away.

Why is DNA evidence always stored in paper bags instead of plastic?
|
I had to look it up, but the answer is apparently moisture. Paper bags are permeable to moisture where as plastic holds in moisture. Anything that is wet goes into paper; anything dry goes into plastic. More specifically, moisture promotes bacterial and fungal growth as well as promotes enzymatic activity. Any one of these things can degrade DNA.There's a paper that shows DNA evidence that was dried out compared to just stored has a massive DNA.retrihttps://_URL_0_ rate difference.

How can deaf people who've been given Cochlear implants understand speech?
|
> the woman has been deaf since birth and therefore has obviously never heard sound before Not true. "Deaf" doesn't mean "completely unable to hear anything". Deafness is a range, and not a binary on/off description. Her hearing was just really, *really*, **really** poor. But she **had** heard before , and knew what speech sounded like. Someone getting a cochlear implant after being *completely* deaf for their entire life **can't** understand speechI'm a Deaf Ed teacher, half of my students have CIs. This is something I really don't understand about these videos! My students work hard every day to learn how to maximize their auditory potential. Auditory goals include "Following one step directions" and "Identifying familiar nouns." Keep in mind, I do work with young kids who have lots of therapy and education ahead of them. Anyway, I imagine with years of speech therapy and developing phonemic awareness, it would be easier to decode speech sounds after having your CI turned on, but really it baffles me in these videos when people who have been profoundly deaf since birth are understanding everything those around them are saying.

why do LED torches have multiple small LED's instead of one big one?
|
Some of them do have a single LED, such as Mag-Lite. Low-output LEDs are much less expensive to produce, so cheap flashlights often will have 25-50 of them ; their overall light output is typically less than those with a single LED. When purchasing, look for how many lumens the flashlight produces, not how many LEDs; more lumens = brighter.Mostly because of heat. LEDs are _really sensitive to heat_. If you make a large LED then you can't put in heat dissipation in relation to heat generation in ways that don't lead to premature burn out. By having lots of small ones you can put room for dissipating heat between each LED.A single large LED gets much hotter than several smaller LEDs. Much easier to handle the heat dissipation. Take a look at this guy. He has massive LEDs, but he attaches them to a heat sink probably 5x the size of the LED. The heat is insane _URL_0_

Why does America send so much aid around the world when it’s own people have a massive homelessness, drug, healthcare, infrastructure problem?
|
Foreign Aid is to a large part a geopolitical tool. It also has a humanitarian aspect, but mostly it is political. This is not only about America , but an answer in general. You are making sure countries are pro-you and stabilised , people from there do not move , countries are influenced culturally as you want, you ensure economic access, ensure the geopolitical grasp in that area . All those things are "pro you", but you also want them to be "contra other geopolitical and local players". Furthermore, a lot of that money goes back into your own companies. Especially regarding infrastructure projects which are usually done by large companies - and those are not from the place you're giving the money toWe send less than 1% of our budget out in aid around the world. Such an amount would not begin to address the issues we have domestically that you name, but it does generate goodwill with other nations while doing a not more to help that nation than it will do here so it is considered a good thing.So first, America doesn't actually send a bunch of aid around the world. We spend about 1% of our federal budget on foreign aid. For America, that's almost a rounding error. Second, it engenders good will in other nations and is just the right thing to do. If you have that much wealth that you can afford it, it's the right thing to contribute and get other countries to like you. Lastly, and probably most importantly, it's a national security priority. People turn to things like drugs, crime, revolution, and even terrorism when they are poor and feel like they have no other alternatives. So, every dollar America sends to other countries helps to stabilize those countries. By fighting poverty, disease, and starvation overseas, we help stop people from feeling desperate enough to turn to violence and harm America and her allies.

Why are spiders unable to crawl on another spider's web?
|
We're not *entirely* sure. There is some evidence that spiders make special sticky proteins with a particular anti-stick protein that only they know how to make, which they coat their feet and legs with. That way, they won't stick to their own web. There's also a lot of evidence that spiders build mental maps, or otherwise can tell which parts of the web are sticky and which aren't. Most of the web isn't, actually. They have a lot of support lines that only hold the web up, and even the sticky strings usually have little globs of goo placed along the line, so if you step carefully and know where to step, you can avoid getting stuck. A spider in a strange web would not know where to step, and frankly would probably be too panicked to step carefully enough. In any case, falling into a web doesn't give you a lot of opportunity to carefully avoid getting stuck: a spider would likely get stuck even in their own web if they fell into it. Unless they can make the anti-stick protein, in which case they would quickly unstick themselves. Also keep in mind that not all spiders create web traps like that. Some go out hunting, and although they still use sticky silk to hold onto prey and to descend from high places and such, they don't build the big webs you're used to seeing. Those spiders would be poorly equipped to deal with falling into a web.

why does crying and being sad make you so tired? [Psychology]
|
Emotional stress and trauma is both physically and mentally draining. Being overwhelmed in some cases can lead to blackouts. Tears, for example, obviously use water and potassium-so excessive crying can lead to dehydration.

Why does my dog go around in circles before pooping?
|
To find the best playce of course. He probably has to check, whether no other dog had the same idea before*five seconds of Googling later* > It’s all starting to make sense. For years I wondered why my dog spins in a circle before depositing her daily double. But now I think I have a clue as to why. Scientists at the Czech University of Life Sciences in Prague have found that, like other animals, dogs are sensitive to Earth’s magnetism. > Dogs prefer to do their duty with their bodies aligned along the north-south axis, particularly under calm magnetic field conditions, report Hynek Burda, et al. in a study published in the Frontiers of Zoology. The field can fluctuate and I can’t help but wonder if it’s on those unstable days that my dog circles round and round like a housefly on a windowsill. _URL_2_ _URL_1_ _URL_0_', "It is many a dog's dream to construct the ultimate shit tornado but to this day there is no record of it actually happening.

Why does a runny nose (post nasal drip) irritate my throat?
|
The mucous sliding out of your sinus cavity and down the back of your throat is drier and irritating. It can prevent moisture from reaching the tissues at the back of your throat. You should give nasal irrigation a try, using either a Neti pot or a squeeze bottle designed for the purpose. Neil-Med is the brand I use, they also make packets of salt you can add to the Neti pot/squeeze bottle that has just the right amount of salt in it. You can also try saline nasal sprays--I prefer Simply Saline, some sprays have a chemical taste.

Itchiness! Why do we feel "itchy" and why does scratching make the sensation go away?
|
Your body is made of cells. Your brain, being part of your body, is also made of cells. Each cell has different things it can do. Cells in your brain let you think, feel, and experience. Your skin, another part of you body, is also made of cells. But there are different typed of cells in your skin. There are "skin cells" and "nerve cells", among others. There are many different types of nerve cells in your skin. These different types of nerve cells can detect different things that happen on your skin. Some of them can detect hot and cold, some can detect smooth and rough, and some can detect when you're pushing on something. You get itchy when the nerve cells in your skin detect something itchy. Then, the nerve cells can send a signal to the cells in your brain, telling your brain that you have an itch. The nerve cells in your skin are triggered by something moving against your skin—so an itch tells your that there's a bug or something small on you. But sometimes you feel itchy, even when there's no bug. That happens because your skin is irritated and the nerve cells are sending signals that they shouldn't be sending. The best thing you can to to stop the itch is to wait for the inflammation to go away, and try to ignore the false signal.

A priori and a posteriori with easy examples
|
A priori means independent from experience, thus 2 plus 2 will always be 4 and can't be changed. It will always exist no matter what - we can't influence the answer. A poseriori means you have observed it happen. Like President Trump is the president of the US. That's based on what you observed. That knowledge wouldn't exist without human observation. Hope that helps.a priori is something you assume. A posteriori is something you learn/observe. examples: 2+2 = 4 is "a priori" because it flows from the assumptions of mathematics, before we know anything about the actual universe or the example. We know it by pure thought experiment. A priori usually refers to something you are putting forward as an assumption, to guide further analysis. So, "assume, a priori, that we win the war, then what do we do?" Now, the parallel a posteriori might be, "I just checked my bad I have 4 apples." That's not about addition or math, it's something you 've actually observed about the physical world. Another example might be something like "we just won this battle, what should we do next?"

What Do ISPs Gain From Throttling Internet Speeds?
|
It keeps them from having to upgrade their network. You could offer everyone the top speed but then if more than X number of people used it they would run out of bandwidth and it'd all come crashing down. They throttle in order to keep this from happening so everyone gets the speed they pay for ideally. Now they've abused it and refused to upgrade their network when they should but that's a whole other point.

What do people mean when they say something "became a commodity".
|
Commodities, generally speaking, are goods and services that have little to no differentiation across a market. Gold, for example, is a commodity because all gold is basically the same; there's no functional difference between gold mined in Colorado and gold mined in West Africa. Agricultural and mineral raw materials are usually commodities. Commodities are often traded on large open markets, like the Chicago Mercantile Exchange. So, no. Porn doesn't really qualify. The commenter may be misusing the word, or they may mean it like a metaphor that porn was widely produced and easy to get.
