What is the weird tingling feeling people often get when they watch ASMR (or other things)
I think I get it? But when people are doing something for me, and I'm learning from what they're doing.
Why do westerners prefer black tea while Asian countries prefer green tea?
My guess is that black tea is fermented and the West wasn't able to get their hands on fresh green tea- so tea in the west is generally black - while tea growing counties can use fresh tea leaves . Black tea is still popular in Asia though.
Does substituting the recommended 8 hours sleep a night for 5-6 hours and a cup of delectable coffee in the morning have any long-term side effects?
Yes. You'll still suffer from sleep deprivation over time if you aren't getting enough sleep, with all of the ill effects of that. Not everyone *needs* 8 hours of sleep, but if you are getting less than you naturally would need there is no drug that will make up for it in the long run.
How does the UK justify that they have a reasonable claim over the Falkland Islands?
Strategically they hold almost no significance, although oil may change that. At the time of discovery they were uninhabited and there was no official claim to the territory. It's now a case of we have British citizens who live there and they voted in favour of remaining British in a referendum so, the islands will remain British. Just because an island is close to your country, doesn't mean you can stake a claim to it.The British settled there. So the inhabitants of the islands are of British decent and want to be under the British crownBecause the people who live there want them to. It's the same logic used to justify pretty much every legitimate claim. When asked, the people of the Falklands say that they are British and that they want to remain that way. When asked if they would like to be ruled by Argentina they decline. But even if they weren't part of Britain, that wouldn't mean they default to being Argentinian. It's an island far outside Argentinian coastal waters with it's own distinct history, culture and ethnicity. They would default to being their own independent state. Argentina is trying the same imperialist bullshit that Britain tried in Ireland, or Japan in South Korea. "It's near, it's smaller, therefore it is mine". When has that ever ended well? The fact that the people live on an island makes absolutely no difference in that regard. From the early 20th Century onwards we 've been using self determination as the basis for legitimate claims of sovereignty and the people of the Falklands have spoken unequivocally in that regard. Arcane historical claims are not, nor have ever been, a reasonable justification for war. Geographic proximity doesn't even make any sense, Argentina is the same distance from the Falklands as the Falklands is from Argentina, the argument that the Falklands should be ruled by Argentina is the same as the one that Argentina should be ruled by the Falklands. The only thing that matters is what the people say.
Why is it okay to drink Everclear but it isn't okay to drink ethanol?
While lab-grade EtOH does contain methanol so that it's not safe for public consumption, I'd like to clear up something missing on this thread. 1) There's practically no such thing as 100% ethanol. It's hygroscopic and if exposed to air, absorbs water vapor pretty rapidly2) You can't take wine, or everclear for example and distill it to 100%. An Ethanol/water mixture has an azeotrope that fundamentally prevents distillation beyond 95.63% FYI: If anyone has great ideas on how to break azeotropes, you will make a lot of money.
Why does the US use commas and periods differently on currency than other countries?
Probably because that's how it's done in the UK. Why the UK uses different methodology is a different question! :p
How does Jurrasic Park, a 22 year old movie, have some of the best CG I've ever seen?
There's only 15 minutes of dinosaurs in the movie and only 6 minutes of that is CGI. There's a good chance what you think is amazing CGI is actually animatronics. The CGI is still very good though.
Why are Americans so patriotic?
It's pretty easy when the US has been one of the most dominant international powers for the last century and *especially* in the post-WW2 period. We saw European powers crumble & lose empires while we helped rebuild them. Economically, we're not doing as well as we were in the 1960s but nobody has really threatened our position.
Why haven't we started using nuclear energy to generate electricity at a large scale?
Because nuclear energy creates really bad waste that is very dangerous, difficult to control, and a lot of it. Also, it's a very fragile operation that must be controlled very precisely. This makes it very expensive and slow to set up and maintain. Finally, it makes a nasty mess when it fails that's really hard to clean up.
What exactly are those people at the doors of Walmart checking on your receipt? And can they legally stop you from leaving after you have already paid for the items you are leaving with?
Everywhere I have shopped its less about checking the contents of my cart than it is about marking my receipt. This prevents theft as follows: For example: At Lowes or HomeDepot: Builder needs 20 2x4's, 4 peices of sheet rock, and 2 tubs of spackel. Builder and helper each assemble a cart with 10 2x4's, 2 peices of sheetrock and one tub of spackle. Builder pays, leaves store, loads truck, meets helper and hands off recipe. Helper takes recipt and leaves the store via a diffrent exit. Builder only pays for half of the materials. A store that checks and marks recipts as they leave will catch the helper when he tries to leave. This scheme can also be used in instances where you only need one item: buy one, take one, return one with recipt ", 'loss prevention and no they can't legally stop you unless they want to accuse you of theft. only at membership places like costco and sam's club can they legally stop you. me at fry's yesterday while walking out. girl next to exit door "may i see your receipt please?" as i walk out, i stare at her blankly and proceed to continue walking out. after i 've walked out "have a nice day"
Why do dogs have different breeds with very noticeable differences, while cats appear to be pretty much the same just in different colors?
While /u/thejennadaisy is right, there's a bit more to it. It's true that we've been selectively breeding dogs for a long time; however, if we'd been doing the same with cats the outcome wouldn't be very different from what we have today. Dogs' DNA is very easy to 'manipulate' by selective breeding. If a change occurs in their DNA, the outcome is very likely to be a healthy dog, that looks a bit different. In cats, when a mutation occurs, it's much more likely the cat won't be healthy, or even viable. So it's a lot harder to get different breeds of cat than dogs.Because cats were all bred for the same purpose.
How is renewable energy more feasible than the alternative if it relies upon rare-earth materials?
1. You spend a lot more energy transporting coal and oil than you would for electricity. 2. Lithium and other chemicals used in battery production are not one time uses. It's not a perfect solution, but it's a better one.
What do they mean when they say Jupiter is a "gas" planet? Could a rocket be shot through it? Could an astronaut (or spacecraft) "land" on it?
For the purposes of this discussion, the density, pressure, and temperature at the center are actually something akin to, but not quite like, a star. Imagine the pressure at the bottom of the ocean, and double it many, many times. It's postulated that it may hail in the center of some gas planets diamond hail. Hot and dense enough for diamonds to form like ice like our water cycle on steroids. Nothing could survive.
Is crooked teeth an advantageous trait in humans? Is wanting "Straight" teeth purely a cosmetic desire?
No, look at the wild animals. You don't see them with wonky teeth. People with bad teeth can survive and reproduce the trait, but wild animals can't afford it. Dogs and people live cushy lives compared to animals and so they can have bad teeth. Here's a woman who identifies a coydog skull as not a coyote or coywolf skull by the fact that it has bad teeth, something you don't see in wild animals: _URL_0_
What causes 'speed wobble' while riding bicycles/skateboards etc. at high speeds
Two wheeled vehicles experience load shift between the front and rear wheel when accelerating/decelerating. The front wheel/steering mechanism can momentarily lose traction when the rear wheel picks up traction . This only needs to be a very small and imperceptible interruption to the front wheel/steering mechanisms grip on the road. Death wobble kicks in when the front wheel momentarily loses traction and there is a lateral accompanying the rear wheels pick up in traction. When the front wheel regains traction it cannot grip smoothly because of this small lateral movement. This starts the wobble which then grows because the front wheel can turn side to side . You can slow and stop the wobble by gripping the handle bars tight but is often unsuccessful. Experienced bike riders will usually apply the front brake to shift more weight onto the front wheel which forces more traction into the rubber and reduces the wobble. You can also help avoid a wobble by having more air in your front tyre because it effectively stiffens the rubber. Hope that makes sense. _URL_0_
Is the edge of a circle with an infinite radius curved or straight?
straight" and "curved" kind of break down. It is necessary to extend those definitions to handle infinity, and there is often no one correct way to do thatThe curvature of a circle is defined to be the reciprocal of the radius: κ ≡ 1/r Take the limit as r → ∞, then κ → 0. I.e. path with zero curvature is a straight line.
This prediction video—it outsmarted me. Is it possible to win?
No, if you follow the instructions it's impossible to end on the square he removes, wherever you go.
Laws that require you to prove you're 21 (or other age) if you're under age X
The point is that if someone looks 40 then there's hardly any chance that they are under 21, so there's no need to check their id. Even if they are much younger than they look, and it turns out they are actually only 32 and not 40.
The universe is constantly expanding. Well what is it expanding into?
My understanding is that the universe is expanding into NOTHING. There is literally nothing out there. I don't just mean there isn't anything out there, I mean that it actually doesn't exist. Before the big bang there wasn't anything. Not even empty space, there was literally nothing, nothing existed. The Big bang caused the expansion of the universe and the creation of space for said universe to expand into.
Why is it not okay to pet guide dogs? I mean, those dogs need love too.
When these dogs are working, they need to be able to fully focus on their job. People's life might literally be at stake. As such, these dogs have been very well trained to associate work time with wearing their vest, and play time with them not wearing a vest. That is when they get all those obvious signs of love and affection and free play time. By petting them while they are working, you are not only distracting them, but you are also compromising their training.
Why is it, in China, when horrendous crimes are being taken place, pedestrians just keep walking?
There's one from the US with a vid of a guy coming to a girl's rescue as she's being mugged. He gets stabbed and the girl just leaves him after the mugger runs away. Vid keeps going as everyone just walks around him as he's begging them to help him. I'd try to find a link, but I'm on my phone. Not just China, dude, people are shitty everywhere. A lot of people simply can't be bothered. Part of it may be due to cultural insensitivity or due to the area they live in. However, to brighten your day, after nearly all horrible events, like 9/11 or the Boston Marathon bombing, you will see people helping everywhere. Canada took in so many Americans, many civilians opening up their homes to let random Americans stay while everything was frantic. Injured runners and bystanders were still trying to help those who were worse off. So, yeah, people do suck, but there's always good people too.
How can my phone with a 5 inch screen be 1080p, but my TV which has a 55 inch screen hot be 11 times the resolution? If that makes sense.
Well there are 8K tvs being made which is quite a bit higher 1080p 16 times to be exact. Of course these tv's costs thousands of dollars though and there's basically 0 actual 8k content out there so there's the issue of practicality as well. Add in that 8k is really only useful for really large screens like 100 inch because otherwise it's a case of diminishing returns. Most people cant afford those tv's some people cant even fit such a tv in their place of residence. Long story short though there's no reason to have a 55in tv be 8k you literally won't see a difference because the pixel density will already be so much that you cant tell and the tv will be exponentially more expensive. Phone are actually reaching the point of diminishing returns as well. 2k - 4k resolution at 5in is pretty much the max that people can discern any difference and we won't benefit from any higher unless we go even bigger which is unlikely for smartphones.They could, but it would cost hundreds of thousands of dollars, especially due to the fact that you need a speedy computer to process data on all those pixels. There is a reason why your phone and your TV cost about the same amount of money.
Why can't we do like a hundred airstrikes a day against ISIS
ISIS aren't exactly in big castles of evil. They're fortified in towns and villages containing people who aren't fighters, including women and children. If we launched air strikes against them, then they would be telling the truth when they say that the West murders innocents
Why are bathrooms all gender specific, rather than having one restroom with all stalls, for both genders?
From an economic standpoint, it's significantly cheaper to provide a men's room with urinals than to provide 2 gender neutral/nonspecific restrooms or one big restroom with stalls. Stalls take up more room, cost more to build, cost more to maintain, and are harder to clean. What a lot of politically minded gender-baiting people tend to forget is, that's its one thing to take over a men's room and pretend it's gender neural at your local college, but it's a whole OTHER set of costly economic problems to actively build new facilities for this purpose somewhere else. You are basically telling society to build bigger, more expensive bathrooms to cater to less than 1% of the population. That's never going to happen no matter how progressive or tolerant a society may be. The cost/benefit is simply not there.
Why is fruit good for you but fruit juice bad for you?
Fruit juice isn't bad for you, per se, but too much of it is still too much sugar in your diet. The same is true of fruit, it's just generally a lot harder to eat so much fruit it becomes a problem.Even 100% juice has more sugar and less fiber than eating an actual piece of fruit. In moderation 100% juice is fine, just be mindful of the relatively high calorie content and that it will not be able to "full you up" as well as a solid fruit full of fiberYour body can digest liquid faster than a solid, so the natural sugars in that fruit are absorbed quicker.
When commercials say "call within the next 5 minutes" do they really mean it?
In the world of sales this is referred to as a 'call to action'. The central notion being that you will never sell anything if you don't ask a customer for the sale. This is paired with a sense of urgency. If I feel like I may miss out on something by not acting, chances are I will make a decision to act.Think about it logically for a second. How would they know you called within 5 minutes? The commercial is on a bunch of channels at a bunch of random times. It's a ploy. They are playing on the fact that people make decisions when pushed. "Oh crap, this is a limited time offer! I better hurry up and order!"', "it's just a ploy to get you to call without taking the time to think it through. even if you called an hour later and asked for the same offer you would still get it. also, they will use the value of the free gifts to overcome any objections to price you may have.
Why can my eyeglasses take constant dropping and abuse while my phones screen is so delicate?
Speak for yourself, every pair of glasses I've ever owned have been horribly scratched the first time I dropped them on pavement. Even if I paid for the 'anti-scratch' coating and shit. They don't shatter though, because they're usually plastic and they weigh a lot less than a phone. Glass lenses are uncommon in eyeglasses because they will have to be a lot thicker than plastic, and therefore weigh more. Plastic phones are nearly impossible to shatter, but they scratch more easily than glass.Your glasses, at least in the US, have to withstand the impact of a 5/8th inch diameter steel ball dropped from 50 inches, as required by the FDA.In my experience repairing both iPhones and androids it has to do, not with the strength of the glass itself, but with the flexibility of the phones. While Apples have prestine engineering under the hood, they have a solid, aluminum case whereas most droids are plastic. When an iPhone hits the ground, it doesn't have any flexibility to distribute the force. I throw my android across the rooms as a demonstration to most of my clients and haven't broken the screen yet. They still stick with Apple and I have several returning customers because of it. Edit 1: Spelling.
How do reddit "power users" like /u/pepsi_next submit 100+ links every 5 minutes and not get banned as bots?
Reddit is about aggregating content. It's in their interest to have content. What pepsi and the other power users do is find stuff, then know which subs look for that sort of content. Its really easy with porn since there are so many niche subs out there. A single photo could go in /r/bustypetite /r/redheads /r/realgirls /r/girlsmiringirls and /r/trashyboners and do well in all of them. The same can be done with SFW content. Say you have a high quality photo of a young girl with heterochromia and a cat with the same condition. You coul put it in /r/pics, /r/awww and /r/mildlyinteresting .
The vaccination war: Aren't the only people at risk those who don't vaccinate
The very young and the immunocompromised cannot take some vaccines. And sometimes vaccines don't take you remain vulnerable to the disease even after vaccination. If vaccination rates are high enough, those factors don't matter. Even if the 1 in 1000 vulnerable person is unlucky enough to exposed, they are unlikely to run into another one of the 1 in 1000 before being treated. When those numbers drop to 1 in 10, disease is likely to reach everyone who is vulnerable.
Why isn't Google+ really popular?
G+ is actually an okay social site. It takes some time to tailor it to be good. Think of when you first logged in to reddit, you unsubscribed from a bunch of generic subreddits and selected ones you are actually interested in. In G+ you do this with individuals. So it takes some time to make it work well. Not everyone wants to spend time on this kind of customization. Most people just want something to work out of the box, so to speak. I think it's unpopular because google borked it's rollout. Instead of letting it grow organically, drawing people in as more and more interesting people generate content, google tried to push people in, which has caused some backlash.
Why do dogs love their bellies being rubbed?
Doesn't everyone love a belly rub? Dogs just usually aren't as selective about who rubs it", 'My dog hates it. She is one alpha bitch.I was rubbing my roommate's cat's belly the other day, when I noticed his penis was becoming erect. I stopped touching the cat, who then started furiously licking its penis. It then spent the next several minutes rubbing against *everything*. I'm pretty sure rubbing an animal's belly is a lot like foreplay.Anecdote here: the vagus nerve runs along the anterior abdomen. In theory dogs like it for the same reason people like hugs.
why the King James version of the bible is widely accepted when it was the actual bible rewritten for a king? Or is that completely false?
Here's my attempt to ELI5, rather than like an historian. The bible was first translated into English after the reformation; the period when the Protestants split from the Catholic Church. This was around the time of Henry VIII; in the mid 1500's. Protestantism gained a strong movement in England during this time thanks to people like Thomas Cromwell and later queen Elizabeth. They were advocates of providing ordinary citizens with English translations rather than the Latin that it had been written in for centuries. The Catholics wanted to keep parishioners dependent on priests for knowledge of god; whereas Protestants wanted to experience God's word privately or on their own with no middle man. It was revolutionary at the time to own a bible, much less one translated into English- in fact it was heresy and people were burned for it by the church. Eventually, as Protestantism became the official religion of England, the bible was translated into English. The King James Version is one of these translations; he just happened to be king during the time of the translation.
I am 31 years old and could never understand algebra in HS or college. I had to do some math today and suddenly everything clicked and suddenly I get it. WTF happened?
I think along with what others have said, a lot of it comes down to attitude. If you go in to something wanting to learn it and enjoying it, you'll learn more. But unfortunately, school systems rarely do a good job of that.
Why are energy drinks with zero sugar or calories bad for me?
don't have an answer to this but I'd like to know the answer myself. Suspect that whatever is wrong with diet drinks they're certainly the lesser of the evils compared to the sugared alternatives.Have my upvote because I too was wondering the same thing as I down my 2nd *monster zero ultra blue* of the day
How much can my company monitor while using wifi?
The answer to your question isn't a clear cut answer. It depends on what their systems are setup to watch for. Really, they could track everything you do at any given time. PS: Get a VPN and it will encrypt your data so they can't see it anymore. They'll still know it's you on your phone though.
how is the job market able to accommodate the increasing number of college graduates per year?
It's not the end-all answer but people retire and die. New businesses start. Not all graduates get jobs. That, at least, accommodates a decent percentage of graduates.
Jury Duty/Jury Nullification (USA)
So, every time I see one of these threads I ask this and no one ever replies. Can someone just link to where in the constitution it describes jury nullification, and then also link to a court case within the last 10 years that it was used? Those 2 links would clear up a lot and be a great peace of mind to readers who come to these threads fearing they'll read misinformation.
I can't think of a single Chinese food that has cheese?
Cheese is hard to come by in Asian countries, as they have no interest in it. Supermarkets don't sell it and it needs to be imported, or purchased in specialist areas.
In the U.S., how does policy allowing coal mining waste drain into streams help create more jobs? How is it in any way beneficial?
Let's say you have two mines/factories/whatever that are otherwise identical, but one needs to build pollution control facilities and pay pollution control staff, and the other company doesn't. Which one can sell its product for a lower price? If you ignore the external effects of the pollution, healthcare and cleanup, assuming those things get paid for, then it is cheaper to not have regulations. Even if you do pay for those things, it can be other industries essentially subsidising the polluting one by paying a larger share of tax for cleanup. Of course it's madness. But if you think China is 'winning' by building hundred of coal generating stations a year and making so much airborne pollutants it is toxic, then you think mimicking that will level the competitive playing field. China is understandably a bit bipolar on the issue, with efforts to cut pollution but the need to meet energy demands of a wealthier population.
Why is gold so valuable? What keeps the price so stable/high? Why is it a good investment?
First, I wouldn't call the price of gold very stable, and I wouldn't call it a good investment either -- the price rises much slower than stocks, but it makes a decent hedge against inflation. Why is it valuable? Because people value it. Why? It's scarce, divisible, fungible, durable and pretty. Scarceness: basically every physical thing is scarce, but gold is at a particular sweet spot. It's much more scarce than iron or aluminium, but not so scarce as platinum. It's also much easier to refine than any of these. For example, native Americans were basically using stone tools when Europeans arrived, but they had gold jewelry. Divisible and fungible: unlike diamonds, a piece of gold can be split up or melted down and still have the same value. Same weights of the same purity of gold have the same value --- unlike the natural differences which occur in diamonds. Durable: gold doesn't rust like iron or tarnish like silver. It doesn't easily form compounds with other elements. One even needs to use a special mixture of acids the dissolve it. The noble gasses are less reactive, of course, but gasses are difficult to contain.
Since millions of years ago there was a much higher oxygen content, did fire behave any differently?
There is a two part podcast, Visions of Fire, on CBC Radio's Ideas. I know, It is not the answer you're looking for, but that podcast is featuring many interesting facts about fire. You can find it on TuneIn.
Why is the primary braking force on a motorcycle applied to the front wheel?
Op, there is more to it than your question asks! Different driving conditions require different braking techniques. Such as on turns. Or wet roads, etc. Good basic info here from the MSF: _URL_0_ For what it's worth, from a teen on into my mid-late 20's, I rode M/C, some years even my only form of transportation. Got married, had kids, you know the story. Got off the bikes. Then after the kids had grown up and on their own, time to hit the road again when in my mid-50's. So, to get a discount on insurance, I took a State endorsed Motorcycle Safety Class. . Man, I thought I was a good, safe rider back then. But even in this basic class I learned lots. Cannot highly recommend enough for anyone getting up on 2-wheels. Even the instructors said they would take the advanced course every few years to stay sharp.
Why is the picture-in-picture feature basically dead in modern TVs?
Dude! I would love to watch the NFL games on Sunday while playing video games wake up TV MFG's
How are dice fair?
Cheap dice are not fair. They are molded, then dipped in paint and then tumbled until all the paint wears off of the surfaces and is only left in the holes. This causes the faces and corners to wear unevenly. Casino dice are much less rounded on the corners, and aren't tumbled during manufacture. They are much more fair.
if a movie isn't finished, how are the trailers made?
Well the process of cutting a movie can take a long time. A film maker might not have the final cut approved yet, maybe there is a back and forth going on with the MPAA over what rating the film is going to get, and all the cuts that might need made to get the rating the studio wants aren't complete yet. However, if they've wrapped shooting they can cut together a trailer to get the hype machine going.
What's Going on When the Gas Pump Shuts Off Every Few Seconds? How can I prevent it?
It sounds like the automatic cutoff feature that is designed to stop you overfilling your tank. Basically it's telling you that your fuel tank is as full as you needs it to be. Time to pay and go home.
Why do warmer regions (tropical/desert) seem to have so many more poisonous/venomous plants and animals?
My knowledge is based on my AP Enviro Science class. Basically, there is a higher level of biodiversity This is caused by a few things. Firstly, in nicer weather, plants grow better. It's basically a year-round spring in these places. When things keep growing, animals keep eating and energy gets passed around. That creates a problem for the plants and animals being consumed. They need a way to defend themselves. Our good friend evolution, or some deity if that's your thing, takes care of that for them. Over time, they become poisonous. I hope I answered the question. Feel free to correct me if I'm wrong.
Why is 60 a common level cap for RPGs?
There's no fundamental reason why it couldn't be 50 or 70 or 64 for all it matters. So there are two parts that go into it. First is pacing design second is marketing. I'll talk about marketing first because it's easier to understand. What people have found over the years is various psychological tricks you can play on people to get them to think your game is better. Oh Everquest had a level cap of 50, but you have a level cap of 60, that must mean your game has more in it . right bullshit. But that's marketing for you. The second problem is pacing, and keeping enough rewards that people feel like they're achieving something as they play. This also means you need to give the player something at each level. D & D had a 20 level system at once point, but each level gave you a lot of stuff. That makes sense in Pen and paper where calculating leveling up is a relative inconvenient process. But in a computer system leveling up is easy, so you can do the same thing, just . break it up into 60 parts rather than 20. 60 happens to be a convenient number for some developers to work with maybe that equates to 10 active abilities, 30 talent points and 20 passive abilities , but the idea is to break up the process into small chunks player can understand, and where they can appreciate what they are working for and what they're getting at each step, and that it takes a reasonable amount of time between steps. If I wanted to release an MMO tomorrow and make the level cap 20 what would that image evoke for you as compared to WoW at what, 95 now, GuildWars2 at 80, FFXIV at 50 etc. The number doesn't actually mean anything, but how people perceive the number matters and people perceive 60 to be a good number, which makes it a good number.
What is actually going on when i pop my back? How does this compare/contrast to when I crack my knuckles?
I've cracked my lower/middle back, knees, elbows, fingers, shoulders, ankles and neck. I have done this since I was young and am now 46 and have no signs of any kind of joint pains. I lift a bit and think this contributes to healthy joints. I was told that when you crack a joint it releases synovial fluid which acts like a lubricant and might ease tightness, hence the relief felt? Im no Dr .just my guess. But I did want to share that after many years of knuckle cracking i have no issues ", 'I have this weird thing that I can do if I put my arms out to my sides and pull them back. I can pop, whatever that area is about 6 inches above my sternum. Damn it feels good when I do it!I think I may have [Spinal Instability], since my lower back cracks almost every time I move. It hurts after a while.Soooo.. all in all popping my knuckles and back doesn't fuck up my joints and cause arthritis like my parents told me??
how people can be tracked with fingerprints. Is there some sort of universal database of everyone's fingerprints? What?
You may notice in shows like CSI and NCIS, if your parents let a little tyke like you watch them, they look up fingerprints in a database called AFIS, the Automated Fingerprint Identification System. This is a real place where any fingerprints on record can be compared with the one you're trying to match.
Why do teeth rot inside our heads while we're alive, but can remain intact for thousands of years after we die?
I don't know for sure, but I can give v you a few reasons that certainly are involved. 1) corpses get dry pretty quickly, at least on the millions of years timescale. This makes them less hospitable to would be teeth eaters. 2) teeth are the hardest thing in the human body. Hence they have the greatest chance of staying intact long enough to become fossils. 2a) it's important to note fossils are not the original thing, but rather minerals that filled the cavity where the thing was, replacing it with harder rock. 3) our teeth break down because plaque eat the food in our teeth and produce an acid- therefore, no food, no acid. 4) it should be noted-I'm currently studying human and primate evolution- that there are many species we've identified for which we have no bones except a couple of teeth, most only a couple millimeters wide.
Why are some shots administered to muscle and some to a vein?
A more rare reason no one mentioned yet is patient resistance. Getting a needle into a vein can't easily be done of the person getting the shot is struggling with everything they've got. I only saw one example while I was an ER tech. A person on several drugs had crashed their car into a house then punched through a window then he drove to the ER and parked about 5 feet from the door. The person wasn't bleeding badly but was freaking out. They didn't make it past registration/triage before they got aggressive and violent. Security came and subdued them then myself and nurse helped hold the person down. While they were being subdued a nurse had grabbed a dose of something to make the person manageable, I believe it was some kind of strong muscle relaxer or benzo. Once a doc gave the order the nurse gave the person the shot in their arm. No way they could have gone for a vein without a huge chance of missing the vein completely or even sticking one of the guys holding them down.
What are the arguments for lobbying?
Even the smartest, most well informed person in the world doesn't know about every subject in the world. One day, they are making legislation regarding fishing rights off the coast of Alaska. The next, they are discussing radio frequency distribution. And so on and so on. In order to become informed about these subjects, they rely on experts, who happen to be lobbyists.
Why do mirrors only reverse images horizontally?
They don't. They flip front to back. Stand in front of a mirror. Point left. Reflection points in the same direction. Point up. Reflection points the same way. Point at your reflection ", 'Imagine yourself lying on your side, looking at a mirror. Are you flipped left to right relative to yourself, or left to right relative to the room? It depends on how you imagine yourself turning to get to that position. If you roll over, then your left hand would be where the image of the right hand is. But if you turn around a vertical axis, your head is where the image of the feet are. Likewise, when standing in front of a mirror, you could imagine yourself flipping head over heels and your inverted top to bottom.
Why are spicy foods spicy going in and coming out but not sweet and sour foods?
You don't have taste buds in your ass. Capsicum, the chemical in spicy foods, isn't a taste, but a physical reaction to the chemical that burns so it burns your mouth, burns your eye if you rub it after slicing jalapeños, and it hurts coming out.
How would you put out a magnesium fire?
Firefighter here - you can extinguish magnesium engine blocks in car fires with LOTS of water. I couldn't give an exact reason but off the top of my head I would imagine that the water's ability to absorb the heat from the chemical reaction overwhelms the magnesium's ability to continue to burn at the very high temperatures it does.
Why are shadows always black?
Black is the absence of light. A shadow is something blocking light. That said, most shadows aren't black. They are a darker shade of the original color because some light is still getting to it to reflect. But your brain is oretty good at autocorrecting for this.
How do bees/wasps instinctively know how to create a perfect hexagon?
They don't. I keep bees and they often make their cells only somewhat hexagonal. Especially once they get build-up and other schmutzle in there
How are diesel and gasoline engines different?
Fundamentally, diesel engines work like a firestick. If you compress air, it heats up. If you spray some fuel into it, and then heat it past the ignition point by compressing it, the fuel ignites and the heat released re-examine the gasses, pushing the rod back out of the firestick. Diesels have a compression ratio of about 16:1 to make this happen. Contrast this to petrol engines which have a compression ratio around 10:1. They don't ignite the fuel through compression, they use a spark plug to start the fuel burn. After that, it's all the same. Now the reason diesels are allowed near the sensitive radio station is because sparks and high voltage ignition circuitry produce electrical noise. A diesel has no ignition system beyond the compression in the cylinder itself, so there is no electrical interference to upset the radio station.Gasoline uses a spark from a spark-plug to ignite the gas, Diesel just needs to be compressed enough to get hot and then ignites. When spark-plugs go off they make a teeny-tiny arc of electricity which also sends out a wave of electromagnetic energy, which radio telescopes can detect.
If minimum raise is increased how will it benefit those who already have jobs?
Theoretically it will benefit those who work in minimum wage jobs, since they'll earn more money. In actuality, it's more complicated than that, since inflation will also increase and sooner or later they'll get stuck in a similar or worse situation to the one they're in now.
Why is critical thinking not taught as a standalone, staple subject in the same way maths, English or other subjects are?
I don't know in US or Australia or anywhere else. I got teachings on critical thinking while studying Philosophy in Highschool . The teacher was emphasizing it when comparing one author to others. Also got very heavy logical training in that class: discourse analysis, modus tolens & ponens, truth tables, reductio ad absurdum etc.I still remember that class as the most profitable in terms of learning how to think, even if the subject itself is easily forgotten.I agree that this is something that should be taught earlier in school. I got some legit critical thinking courses in college but never knew there were best practices for that kind of thing until then. On a side note, this book is free and awesome: _URL_0_Critical thinking was an optional module in my college. mainly aimed at students looking to go to universityBecause the advertising lobby and the politics lobby lobbied the politicians to secretly prevent this subject from being taught in elementary school. People who grow up with critical thinking skills are far more difficult for the people who subsist on manipulation to manipulate. I have no evidence for this hypothesis but it is clearly not in the best interest of the political elite for the common American to be able to see through their BS. If normal Americans realized how far they were bent over and exactly what the government was doing behind them, they might wake up.Hmmm. Simple question, complicated answer. When modern schooling was established, they were basically rearing children in such a was as to make them perfect for factory labor, ya know, speak when spoken too, ask to use the restroom, sitting in rows, graded on an a to f standard the same way that products are graded. Critical thinking was not exactly something that was necessary, and may have even been harmful to the work force that they were being tailor made for. Education still hasn't caught up to the times. Even when it was unveiled it was outdated.
Why 4-chan and its troll lean so much to the right of the political spectrum
I think largely because it's unmoderated and anonymous, meaning the more unstable amongst us are able to post whatever crazy things they want to post, putting off more moderate people, and attracting extremists.
What is the purpose of the puffy ball on top of a winter snow hat?
I'm so sorry that I can't find a source, but I have an answer to this. The pom pom originally hung down from the top of the hat and stayed next to the face. With the pom pom in this position, the hood was held away from the ear so that a hunter could still hear, even with a hood on. Now it's mostly there for style, I guess.Thats decoration man. Its just for decoration. Thats it and thats all man. We do it for decoration.This is the least Canadian sentence I've ever heard.I knewn someone whose brain was saved by his pompom. He was a kid, playing stupid kid games, and his friend hit him over the head with a shovel. He still bled and had a headache, but thankfully no cracked skullwhen traditionally knitted, you 'd gather the strings at the end to make it a hat shape and these turn out to be the pompom/puffy ball. otherwise, it would be a knitted tube shape thing. hard to explain. these days hats are just made with them for decoration. lol "winter snow hat" yes I'm Canadian.Also it gives you something to do with some of the leftover yarn, since you probably won't have enough left to make another hat or matching mittens or whatever. And they look cute on little kids; you have to have your fun before they get old enough to rebel against your whimsy.I thought it was to prevent snow buildup. Thats why some are on strings. As you move, the ball moves and help knock snow off the cap.
Why are so many US food products not sold overseas, despite the market for them?
Food in Europe is regulated to a much greater degree. Far fewer chemicals and dangerous preservatives. For example. McDonald's fries in the UK have 4 ingredients. In the USA it is 14.
How do they ensure such precise amounts of fat (say 20% fat / 80% lean) in ground beef?
I used to work on large scale grinding systems for hamburger and sausage factories. One particular system had a tank of pure fat and ground up pigs with a somewhat know lean percent. When the ground hog traveled across the factory on a conveyor it passed a big optical sensor. It used UV light to measure the lean point OKly. Then as much pure fat was pumped in to the mixture as allowed. I could go on about the meat factories but y'all might stop eating sausage. That's not the point. Sausage is a gift from god.The meat/fat ratio is determined by the fat content of the lean . For instance most of the rump is 80/20, the shoulder is usually 70/30, the loin 90/10 and so on. This is fat INSIDE the meat, not the white stuff around it. The butcher can declare meat/fat content of the ground meat by knowing where the meat came from. Adding fat to the ground meat is simple math from there and its "watering down" to a desired ratio usually for burger meatI worked at Costco meat department for a short time and for the ground beef we would take a small sample and put it in a matching that would squish/heat it up and tell you the exact fat percentage. They take their precision seriously.
- If deadly viruses, like ebola, ultimately kill the host, how do they evolve, or persist to an epidemic level?
If animals, like humans, ultimately die, how do they evolve, or persist to spread? It's because it takes a shorter amount of time to spread to a new host than it does to kill the current host. Similar to how humans, or other animals, reproduce and spread before they died. They reproduce and the next generation continues on, they go to the new hosts, the new towns, etc. While the virus they were essentially born from stays where they are. Those small communities with no medical attention ultimately act as their own quarantine. They aren't large enough for regular travel to and from, so the virus doesn't spread. And people ask this kind of question assuming that the virus is intelligent somehow, that it's trying to kill the person and reproduce. It's only intention is reproducing, the death of the host is a side effect of the immune system attacking it.
Do supercomputers have similar parameters like ram or hdd size or something entirely different?
Supercomputers are generally built to the particular specifications of their application, which means they don't have any well defined specifications. You might for example have a render farm for a movie production team which is optimized for video rendering, or you might have a computer which simulates molecular interactions in order to do pharmaceutical research. While both of those applications require far more computing power than the average computer the types of computation differ and the setup would differ. Some supercomputers can perform up to ~~96~~ 93 PFLOPs, or 96 quadrillion floating point operations per second .
Why many employers hold your first paycheck
It is not legal in the US to hold a paycheck as you described. But what is probably actually happening is there is no paycheck to hold. You don't get paid on Friday for the same week, you are paid for previous weeks. So if you started on a pay week there is no paycheck that payday for you.Nobody is "holding" your paycheck. If they are, that's illegal. Your paycheck will tell you the start and end dates for the pay period. Most companies are about a week behind to allow them to process payroll. As an example. The pay period for January 1 - 14 is likely to have checks issued on the 21st. If you started January 15, you won't receive a paycheck on the 21st. You'll receive your paycheck on February 4th. It's a long time to wait, but that's because the pay period could be for 2 weeks with one week to give the employer time to process the payroll which includes tabulating hours, submitting them to a company to ensure proper employer/employee taxes are taken out and checks are issued.They're not holding it. You just have to wait for payday. Your first check will be for the same time period that your coworkers are being paid for. Depending on pay frequency and when you started in pay period, you could wait up to two months for first check.
How does the sushi on those sushi-go-rounds (conveyer belts) stay fresh? They aren't chilled and no where I dine do they look monitored time-wise.
So I have restaurant knowledge but the majority of this is speculation because I've never worked in this type of joint. A reputable restaurant will have some sort of policy regarding when things get pulled. American food laws, though they vary per state sometimes, generally say that things don't need to be held at temp if it's only out for four hours. Four hours isn't enough time to develop anything that'd hurt you. As far as sushi goes, order sushi and stick it in the fridge for a while. It's an unpleasant experience. The rice hardens up and the fish is too cold to truly taste. Sushi is meant to be room temp. A reputable conveyor belt sushi place will have a means of tracking when things go in and come off, and they're baking the waste into the price you pay. A disreputable restaurant won't give a shit about when things come off and will gladly feed you no matter what.
Why has Facebook had so much more staying power than MySpace did?
In short, The code was messy. Just a sampling of some issues. It didn't work well across all browsers, or with screen readers. The site was prone to phishing attacks. Spyware was frequent. Spam was everywhere. Users were able to add their own code to the website, which meant that the pages looked awful with ugly background and flashing elements, but perhaps more importantly, that hackers had an easy time exploiting the site by injecting script. For instance, a hacker once wrote a script that made him friends automatically with everyone who viewed their page, and afterwards, everyone who viewed the page the pages of those people as well, until he had millions of friends in a few days time. If these issues were fixed early on, we might still be friends with Tom.
If older cartoons and animated movies were drawn by hand, how did they get the coloring so even and clean, unlike paintings for example?
To add to what everyone else has listed here as far as frames go they painted far less background frames and body frames. You've noticed the background loop I'm sure. You'll also see that most cartoon characters have some form of break at their neck, sometimes its a tie, or a collar or something along those lines. That allowed to them to use the same body frames but just paint new head frames .
Why do different languages have different words for countries?
Because laguage users come up with their own words for things, and they don't always adopt somebody else's word for that place, even when those people actually live there. So, French people know Germans existed, but they didn't talk to them much, so they called them Allemand Meanwhile, Germans call themselves Deutch, and their homeland deutchland. Later on, more Germans and French people start talking to each other, but both groups already have names for Germans, so the French keep their own word, because deutch doesn't sound very french, and why switch?
Does genetic testing ever reveal good news?
This is a bizarre question, but I'll bite. Any time you are revealed to not have a genetic predisposition to a certain disease, that counts as good news. No predisposition towards colon cancer? Awesome. That counts as good news.You do have to realize the question is almost like asking "does the mechanic ever give you good news?" Most people go to the mechanic for a tune-up, or when something is wrong. The mechanic performs a series of diagnostic tests as part of the routine maintenance, or to address the complaint. It is not their job to appraise the value of the vehicle and comment on the good parts. Likewise, "genetic testing" is done with a purpose - to see if you have some genetic disorder to be worried about. With that in mind, you should see how ill-formed the question is. The answer to your question is "because most tests are done to see if there is bad news". Also keep in mind that "genetic testing" is not one, singular test where you input pages and pages of DNA, and the computer spits out pages and pages of information on every single gene. They look for specific areas, with a specific purpose in mind. So even if some genetic testing can be for "beneficial" genes, you won't get the "good news" if you're not testing for it - and there is little reason to test for it in most situations.CONGRATULATIONS YOU DON'T HAVE HUNTINGTON'S That's how you can have good news, they tell you don't have something, or have the least worst thing. Maybe you find out that you have a higher chance of kidney cancer, you may consider that better than say, heart cancer, because kidneys are more common and can come from a live donor, and there's dialysis for failing kidneys, failing hearts get complicated.
Why is it unhealthy to consume Human Meat and is it still unhealthy if you cook it?
Not sure why you'd want to eat the long pig. Have you seen them? Disgusting creatures. Long story short is you can eat human meat, and certainly people have done so for survival purposes. But cannibalism increases risks of certain diseases. Others have mentioned prions. These are defective human specific proteins that didn't fold quite right. The problem is they're a similar shape to useful proteins, to the point where the body can't really tell the difference. Think of like trying to screw a metric nut onto an imperial bolt. You might be able to get it to fit, but you're asking for trouble. Something's going to come loose or otherwise break eventually. Eventually these bad proteins build up and start blocking normal biological processes. In the brain, this causes a wasting disease similar to Alzheimer, called Kuru. It was first documented in an indigenous tribe in Papua New Guinea, who consumed their dead as part of a funerary ritual. One individual was infected with prions, and the others got the disease by consuming them. These prions aren't necessarily destroyed by cooking.
Why do MLMs seem to be growing while simultaneously all other purchasing trends are focused on cutting out middlemen (Amazon Prime, Costco, etc.)
For most MLMs, the product is not the product. The product is made to look like the product, because that's the only way it is legal. However, the actual product is the 'business', the notion of being able to quit your day job by promoting, selling, and signing other people to the business. The items being sold are marketed as being so special that they can only come from a single source, a special proprietary process of the company, the mind of the founder, or a secret special formula, it's how the company convinces people that regular retail doesn't suit the product or the goals of the company. This gives many MLMs immunity from the current online shopping trends by convincing people that it is necessary to have 'trained representatives' sell the product, and they making it appealing by building a model where anyone can be a representative and potentially make a lot of money. Though, at least in the income dislaimers I've seen, less than 5 percent generally make more than minimum wage on a regular basis.
Why has the entire world standardized on Arabic numeral (1,2,3.. etc), even though we aren't standardized on alphabet or language?
three", and not really for doing calculations. **tl;dr** Middle East was the center of major trade routes in the middle ages. Arabic numerals were more efficient than most existing number systems, and were spread throughout the globe. **** *edit: spelling/grammarThai, Laos and Cambodia have ours too, ๑ ๒ ๓ ๔ ๕ ๖ ๗ ๘ ๙ ๐', "try this one, OP, in Ethiopia they don't even use the same calendar OR clock we do! _URL_5_
At roughly what age does learning a new skill (an instrument, a language, ect) become more difficult?
It is more of a continuous degradation of brains ability to generate new cells, also known as neuroplasticity. It's at its peak in very young childhood and then gets continuously lower. EDIT: I realized I didn't quite answer the question, so to make it clear, difficultness of learning brand new things gets progressively harder as neuroplasticity decreases, there is no breaking point
Why does the United States have a disproportionately high number of the top ranked colleges/universities compared to the rest of the world?
Okay wow I can't believe that no one has mentioned this But elite institutions are all private run, unlike most rest of the world that has state funding for all of it's schools, it makes it more competitive, and the alumni donation thing makes investment capabilities soar. T
Why were lions such a commonly used symbol in the dark/middle ages, when none existed in the nations where they were used?
What's the more powerful symbol for a lord wanting to show his power over other lords as well as the common folk that are supposed to serve him unquestioningly? The local breed of foxes, which everyone's seen, everyone knows isn't a huge threat, etc. Or a lion, that roams huge lands they've never seen before, could kill a hundred men with one swipe of its paw and whose roar causes thunder? Family crests were about sending a message. Once word gets around that this big maned cat is brave, fearsome, etc. then people will associate it with the family.
Why is incest between two consenting adults considered wrong?
For the same reason that we consider smoking or drinking while pregnant to be wrong: maybe nothing will happen, but you've got a higher chance of bringing a child with a painful life into the world. If there's an easy way to avoid those odds, we should be taking it.because one"whoops" and you get one-eyed, knuckle dragging retards for kidsIt appears nature, not just nurture, has some answers to this question. Researchers are just beginning to tease out, so this is not a definitive answer , but it appears as though there are drastically different networks in the brain that are "activated" when humans think about sex with a relative, compared to those that activate we think about other disgusting things like feces or heinous crimes. In other words, there is evidence that this disgust is hard wired, not just taught to us by society.I've been told that cousins are far enough apart to have kids as safely as anybody else. That said, I think it's just gross. Also, that would have to be the most awkward break up possible.
Why do human beings, as a species, get such enjoyment from picking on each other and hurting each others' feelings, even among supposed friends?
Well really some people don't care about other people because they literally cant feel guilt or empathy. Some do it so they don't get picked on themselves. Some don't know that they are taking things to far. Mostly it is just like with other social animals they have the instinct to establish a pecking order.
Why doesn’t the United States have a high speed rail system?
The US and Europe are about equal in land mass. However when it comes to population density, it's a much different story. The total cost per person for the same amount of lines built would be drastically higher in the US. Also the amount of people it serves per square mile would be reduced. Realistically for the US's population density, it doesn't make sense .yet. American culture also favors owning your own things and doing things the way you want on your own time. If I want to right now I can pack whatever I need and travel wherever I want in the continental US and not have to fight anything or go through anyone to do it. Solution that solves both problems. Tesla is testing out hyperspeed tubes for travel that can take individual vehicles . This can solve both problems.
Why did humans evolve with such vast differences between individuals' singing abilities? Was this ever a part of natural selection in the se way as looks, intelligence or physical capability?
Singing is also a relative term. What one culture counts as good singing abilities may not relate to anothers. Consider the throat singing done in Arctic cultures. It's just a skill, rather than an evolutionary function.
Why I have to worry about polarity (which way I plug it in) when I plug things into a wall socket
It depends. If the device ultimately is running on DC electricity, then it probably doesn't matter, as most AC DC converters use something called a bridge rectifier to do the job which will automatically work out which side is positive and which is negative or ground. Things like lamps also don't matter, and you correctly understand why. The problem comes about if the product is poorly designed, and what should be the neutral wire touches the body of the device . If a wayward electrician happened to install the outlet with the wires reversed, you would be exposed to mains electricity by touching the device. Another reason is that sound systems generally all need to be plugged in such that the power they receive is in the same phase, or you will get some hum in the sound. If you flip over a plug you will get power that is out of phase with the other outlets on that breaker.You need it for safety, mostly the mentioned switch thing, plus for traditional screw in light bulbs, which have the screw shell as part of the circuit. That needs to be connected to neutral, so that it does not become dangerously live. Some equipment have high impedance bond to neutral, which may ever so subtly "light" the chassis if polarity were reversed.
Why do they leave the lights on at night when there is no one at school?
Many places have a school house lighting law that mandates primary lights in school buildings be left on. Why, I'm not really sure. Claims cover burglary deterrent, safe zones, old ballast lights aren't easy to start up, etc. I've always thought that it had to do with making a public building a safe place to go, day or night. If you're in danger you have a well lit place to seek shelter, even if you can't get inside, and wait for police who routinely patrol the building. But some places have internal lights, which can't be seen from the outside, that never shut off. I'm a teacher and in my classroom, with no external windows, I have one light that can't be shut down. When I turn my main lights on it goes off, when I turn my lights off it comes on. I suppose another reason is fire safety, if the lights are off and people need to get out quickly, they don't have time to get the hall lights up. We also leave extra lights on in particular problem areas to deter people from trying to get in and to give non-night vision cameras adequate light.I was told that while it is partly for security reasons but that having fewer cycles of the ballasts control box of florescent lighting fixtures means that they need to be replaced less often which is a pain in the arse and they contain PCBs. Anyone know if there is any truth to that??
Why do people generally dislike Piers Morgan?
I don't know what you're talking about. He's very, very nice and never interrupts people.Because hes a cunt? I had a good laugh when he was trying to lecture you yanks on gun control haha!Something about wiretapping when he worked for the Daily mirror.Because when he was editor of the Daily Mirror he allowed hoax photos of military personnel abusing an Iraqi to be published claiming them to be real despite the fact there were a number of glaring errors in the shots. The Queen's Lancashire Regiment claimed that this had damaged their reputation and put British service men and women in danger. EDIT: He was fired for this after the paper conceded the photos were not real.
Why is it more likely to be windy when it's cold?
I'm pretty sure it's in some way to do with pressure, I think when it's warm there are low pressures, therefore low wind, and vice versa.
In relation to BitCoin 'mining', what is stopping someone like Google with vast supercomputer supply from making money though this?
Isnt the creator of bitcoin unknown? Arent miners putting tons of computing hours into extending a formula, which is unique and thus identifiable as currency? I think it's possible for bitcoin to have an alternative, parallel existence: the value of the currency trivial compared to the computing hours put in to extend a formula.
What exactly is a VPN, and how does it work?
A VPN is like an invisible tube that connects from one person or place to another person or place. This tube lets people secretly share computer stuff between the two, or let's one person or place use the Internet that's at the other place.
Why do cuisines incorporate more spices in hotter climates than in cool ones?
Spices don't grow in cold climates. It's as simple as that, really. In English cuisine, for example, herbs are widely used because they grew wild in England whereas spices needed to be imported at exorbitant costs.In addition to preventing spoilage, spices helped to cover up the taste of spoiled meat, which is actually reasonably safe to eat when fully cooked.I've heard its to make you sweat, which evaporates and makes you feel cooler.
Capital Gains tax and Income Tax, why do rich people have lower rates?
Income tax is a direct tax on the money you make from things like wages and salary. The rate you get taxed depends on the money you make, and the marginal rates vary from 0 to 36%. This is how most of us pay most of our taxes, because this is how we make most of our money. Capital gains are, generally speaking, investment income. They are taxed at a much lower rate on the grounds that, but the time you receive money from the investments, they've already been taxed . The reason that this becomes an issue is that, in general, rich people make a lot more of their money from capital gains, and this end up paying a lower percentage of their income in taxes. So, let's look at a real consequence of this, by taking a simplified example. Person A is a computer programmer making 80,000 a year. In the simplest case, this person will pay about 14,500 in taxes for an effective tax rate of about 18%. Person B is a millionaire that doesn't work at all, and makes 80,000 a year from long-term investments. In the simplest case, this person will pay about 6500 in taxes for an effective tax rate of about 8%. Note that either person could take advantage of this, but middle class people like person A are lucky to have 100,000 to invest, and therefore would be unlikely to make more than 10,000 a year this way . Person B, with millions to invest can not only take advantage of better investment opportunities than those available to Person A, B can also spend money up front to reduce future tax burdens So, the bottom line is, a really rich person can make more money than a middle class person without even working, and when looking solely at income vs. taxes paid, they will pay a lower percentage of their income than the working person.
Why are horses so submissive to humans?
In addition to what others have said, I'd add that horses do not necessarily perceive size and strength the way we do. Humans are genetically trained to look for patterns and be smart about stuff. Horses don't necessarily realize that you are smaller than them and that they could kill you easily. I've seen my oldest daughter grab a huge horse by it's bottom lip and pull it across the pasture even back when she was like 14. If you act like you're in charge, they don't always realize you're not. They will challenge you, but if you're smart enough to react in the right way, they back down. In short, we're smarter than they are and experienced people know how to convince the horse that they're in charge.
Why cant nerve's causing discomfort / constant pain be "killed"
It's been tried in cases of 'phantom pain', when people feel pain in limbs that aren't there because they were amputated. The phantom pain tends to return anyway. If it's being made at the ends of the amputated nerves, the new ends after the cut cause it again. If it's being made in the brain, messing with the nerves wouldn't help.
Why does America need a $58bn increase in the military budget if it's already more than the next 8 countries combined?
2 primary reasons. There was a requirement to be able to wage two full wars. This means that while they are fighting a war in iraq, that they can still defend other territories as needed. This leads to the other reason: that there exists many contractual agreements with other countries that while they have stations on foreign soil, that they would agree to defend said soil. It takes large sums of money/resources to defend one's country in order to abide by certain un standards, and some countries can get away with this requirement because the american army is their defense. There are other reasons, but the bulk of why the NA budget is so enormous is because of these. The reason places like norway doesn't have a military budget is because the usa does it for them.
How does massive amounts of snow not cause flooding as it all melts?
It doesn't melt all at once and melted it's less water.Remember also that 13" of snow = 1" of rain. So a 4" rainfall is 4\'4" of snow. Now a 4" rainfall will flood things like hell, but snow melts pretty slowly. So it's 4" over 1-2 weeks, which is often not flood levels. Also snow "drifts" against walls. It's probably 1\' taller against the wall than the average snow level, higher if the windspeed is high.My area is pretty close to sea level, and at least once every spring we have a big rain while there's still snow on the ground and the ground is still frozen. Our storm drains back up, streets flood , the sidewalks are walled in by piles of packed icy snow so rain accumulates in the sidewalks, and the flooded sidewalks have a nice solid layer of slick ice under the water that's developed from months of people packing down snow by walking on it. It's REALLY fun. But then it all melts and we get on with our lives. Having quality reason boots with great traction helps.Sublimation- a portion of the snow evaporates directly into the atmosphere.
How do they transform Fenway Park into a football field with almost no evidence that it usually is a baseball field?
Just take out all the clay. It's a big pain in the ass, that's why the raiders just play over the infield for the part of the football season that overlaps with the baseball season, and the field looks normal again once baseball ends and they can remove the infield.When did they transform Fenway to a football field?
Why can't scientists just make better antibiotics?
People are working on it. However, this isn't as simple as taking some current antibiotic and turning a volume knob :) It requires several levels of time consuming, expensive, and complex clinical trials. It takes a long time to know for sure that whatever you've come up with both works and is safe for use.
Why are we trying to colonize on Mars rather than Venus?
Venus, while similar to Earth, has a runaway greenhouse gas effect that causes the planet to have a temperature of nearly 900 degrees F, making it inhospitable to pretty much everything we would want to use there. We don't have the means to fix that problem. We can, however, engineer equipment that works in cold temperatures in places like Mars.
Investing money for the future.
> I'm 17 looking to invest with money around 100$ to 300$. I recently had a similar conversation with a friend and I think my advice still applies -- at a young age with small-ish amounts of money then traditional investments won't do much for you. Yeah sometimes people get lucky with picking up some investment that explodes and they sell for a much higher price then they bought it but if it were that easy then everybody would do it. What investing can do for most people is help steadily make you a little bit of money on the side of your normal income at the risk of losing some of your savings. What it won't do is turn your $100 into $500, at least not quickly. If you're planning to go to college, then saving for that is possibly the best investment you could make for yourself. Even $100 could get you several weeks of tutoring which could mean the difference between an A and a C in a class. Or to think about it another way, if a college loan has a 5% interest rate and you pay it back after a year, then putting $100 into your college fund instead of taking that $100 in a loan means you just saved $5, which is a decent return on $100 worth of investment.
Bacteria become resistant to antibacterial products but why not bleach and alcohol?
I know this isn't ELI5, but these are the underlying mechanisms. Bacteria are little guys with cell walls to protect them from the world. When we put something in say a dish to kill said bacteria, they react in different ways in order to protect themselves. When a bunch of a substance comes to the bacteria, it has four choices: refuse, spit it out, tolerate, neutralize. This sounds similar to humans with foods, but back to bacteria. The bacterium crawls over to your antibiotic in question and several things can happen. If the bacteria doesn't recognize it , then it may be absorbed as possible food/pass through the cell wall. If the bacteria has learned that this antibiotic can hurt it and has a protein to identify it before it gets in, the bacteria will ignore the substance. If the bacteria absorbs the substance, then proteins inside can identify it as a hazard and then spit it out . The bacteria can also recognize the substance, and make a protein to break up the substance so it is no longer a threat. Finally, the bacteria can just learn to tolerate the substance through continued exposure . So how come bleach/alcohol ALWAYS seem to work? They're such small substances that you can't stop it from getting in, that it can't be broken down further, or if it is broken down then it will become more toxic than the precursor. Other redditors have ELI5'ed this, but a full answer may help some understand it a little better.Alcohol desicates the outer protective layer of bacteria and eventually kills them. Hydrochlorite, the main component of bleach, is a very disruptive agent that will also disrupt the cell walls of bacteria.
