Why it's expected for companies profits to grow for each year forever...
Most companies that you know of, like Microsoft or Samsung, are funded by selling parts of the company called shares. Each share shows ownership of a *tiny* part of the organization as a whole. So say company A sells 10,000 shares to raise money for their operations and I buy 100. I technically own 1% of the company. However, here is another important thing. The value of the company changes over time. At the start when company A was selling its shares it might have been worth $100,000 so each share was worth $10. But if the company doubles its worth next year then each share might be worth $20 . And now the shares that I have bought have doubled in value also. I am now richer because the company grew. And remember I said that public limited companies primarily fund themselves from these shares. So when investors who buy shares see that company A has some great growth they will be more inclined to invest in company A because the investors want to make money too. So, in order to attract more investors so it can raise money for its operations company A must always be growing otherwise the shareholders will become unhappy, and don't forget some of them might own more than just 1% of the shares and therefore more than 1% of the company and so have a lot of influence and invested a lot. EDIT: Inflation is also pretty important too. Money because less valuable over time so if some bigshot investor spends $50 million on shares for a company and there is not growth. Next year that money will be worth $550,000 less at current inflation rates. Nobody wants to lose money so they won't invest in a stagnant company
Disregarding microscopic life forms, why is it so difficult for us to find intelligent extraterrestrial life when so many planets, stars and universes exist?
In all the history of the Earth, it has only had intelligent life which could possibly talk to other planets for 50 years. Out of several billion years. How long will we remain capable of this? The chances of two different intelligent lifeforms existing around the same time and location to be able to communicate is small. Possibly we are the first in our galaxy. Possibly we are the last in our galaxy. Other galaxies are far too far away to even consider communication being viable with. Alternatively, once a species starts communicating outside it's solar system, it's eaten by a grue.Space is really really really big. Traveling at 17000 kilometers per SECOND, it will take voyager 1 over 70,000 years to reach the nearest star system.
by the act of taking honey are we not killing the bees? I mean the reason why they make honey is to survive the periods of the year that flowers are not available.
* beekeepers raise bees in areas where they is an ample supply of food sometimes they plant flowers explicitly for the bees* honey bees are chosen for their ability to produce honey the varieties human use produce far more honey than they need* humans don't take all the honey, they leave plenty behind for the bees
Why can my phone load and play 1080p videos seamlessly but when it comes to some .gif/.gifv it takes minutes to load/stutters like King George VI?
Also video is composed using a codec, most of which are more and more standardized. Some of these standardized codecs, like Mpeg2, Mpeg4, h264 and very recently h265 are being accelerated by the SoC . So even though it's more work, your phone has an offload engine for that work which makes it very easy. In some video playback apps, this is called hardware vs software decoding. Software is the CPU doing it without the special accelerator. Hardware is leveraging that offload accelerator.
it's 2015 why don't window wipers wipe the whole windshield?
Because you're going to have to make a system that goes vertical or horizontal. To do this for going to have to introduce a joint that is going to have to be manipulated adding more complexity, more parts, tight tolerances, more weight and use more electricity to the system. All of this for a system that is going to clear what, 15% more of the windows surface? Doesn't seen worth it.
If all of the gold in the federal reserve bank of NY disappeared, what would happen to the economy?
Not to stray off topic.. but your girlfriend isn't capable of explaining this to you? She's in school for economics and can't explain this basic, basic concept? I'd want my money back.
What are the fundamental differences between a software engineer and a software developer?
systems architect" and a few other things. My job has always been pretty much the same shit. Writing software is writing software. In some places, being an "engineer" carries the connotation of being more structured & rigorous but in others, they just slap the title on every code monkey they have. If you're looking at schools, the only real way to compare them is to look at the curriculum20+ year industry vet here. For me, the difference is simple: A Software Developer thinks of the affirmative cases, the "green light" cases. A Software Engineer is somebody who thinks through all the negative cases, the "red light" cases. If they are building a self-driving car, the Software Developer's car performs better .. as long as its a clear sunny day, there's light traffic, everybody obeys all traffic laws, and the GPS nav is correct. The Software Engineer's car will get you home safe on a rainy night, with traffic jams, safely past the idiot who runs a red light and the deer that jumps out of the forest, handles the unexpected Detour signs, and doesn't even care that the GPS systems are down. If you're building a website, the Software Developer can whip up a slick UI with all the basics working in a day or two. The Software Engineer will deliver a site with encrypted communications, strong security, robust enough to survive a bot-net attack, that degrades nicely when the database is down for maintenanceThis is not always true but usually they differ by what "level" of programming you are doing. Usually asoftware engineer is somebody who works on low level programming where the hardware directly effects how your program. Then a software developer might be a web developer or something. I know this isn't always true, but it is the only slight way to differentiate them I have seen.
How does soaking a piece of clothing in milk remove red wine stains?
Drycleaner/Fabricare Specialist here. The industry standard is a Tannin Stain Remover applied to the stain, with steam added to increase the action of spotting agent. In my experience, it is the best option. It doesn't work 100% of the time, but it's more reliable than anything else I know of.
Why people say "African americans", It just isnt a thing in any country I'm aware of or any other race or ethnic group, I don't get it so why?
In the UK, the first generation of people that came over on the [Windrush] , called themselves 'Afro-Caribbean'. Their children also referred to themselves as such but their children refer to themselves as British.
What's the point of the UN if the US can conduct strikes without the UN's support
If you're going to spit on someone, it's polite to ask them before you do it, even if you were going to do it anyways and the person you're spitting on can't stop you from spitting on them.The UN was made to prevent another catastrophic world war, but even the founders admitted its weakness and only saw it as a first step.Because the world doesn't revolve around America, there are other countries too
Why do I feel tired all day but when I get into bed I'm wide awake?
Insomnia can be brought on by behavioral reinforcement. If you stay awake in bed, lying down not sleeping, you are encouraging for you to repeat that behavior in bed next time. Stimuli encourage behaviors; in this case, the bed is encouraging wakefulness because you're continually doing it. So if you're awake in bed for over 15, 20 minutes, get away from the bed and go do something else. The point is is to encourage your body to be wakeful in other rooms of the house, but in your bed you only want to encourage other behaviors like sleep.
How a body detox works?
Detox is basically a scam, not based in proper scientific evidence. With so many things in life, you can't trust the people selling it, or the celebrities endorsing it. What you can trust tends to be peer-reviewed evidence based in clinical trials.The only real "detox" would be swallowing charcoal or saltwater to puke up some poison you just ingested.The spa treatments or anything you pay for are as bad as everyone else says. People who mean a proper detox as in lowering the level of useless chemicals in your body have a better word for it, like diet or better living. When you eat saturated fat laden food you definitely get more fat in you. Most of the other bad chemicals in the world go out your body naturally , you can speed this up by eating and drinking anything that doesn't add more unhealthy chemicals. Exercising is of limited use, your kidneys clean your blood/water and the waste goes to your bladder.
How come when im in complete darkness and look at something I cant see it very well, but when looking away I can clearly see it in my peripheral?
Because, the cells responsible for your peripheral vision are called rods, they are much more sensitive to that the other photoreceptor cells in you eyes called cones. Although you have both in all places in your eye, rods are more concentrated at the edge. This makes our peripheral vision much more light sensitive that our foveal vision the catch is that rods can't detect color unlike their less light sensitive cousins cones. Here's a trick cover one eye for 30 minutes your eye will acclimate and put more energy into the rods giving you greater vision in the dark, it's said pirates used this trick to see when they went below deck which is why they wore eye patches.
When doctors/paramedics shine a torchlight into your eyes, what are they searching for?
Pupil dilation If your pupils don't dilate, you may have suffered head trauma/brain damage and need medical attention ASAP
How come water expands when it freezes if the molecules become more tightly packed together when a liquid becomes a solid?
Water depends strongly on hydrogen bonding, a weak attraction between the polar hydrogens of one molecule and the polar oxygen molecules of two adjacent molecules. This is responsible for many of water's properties. In a liquid state, there is enough energy present to constantly break and reform these bonds, letting water flow and move. When heat energy is removed, the water sets up in a rigid crystalline structure. There is no longer energy sufficient to break the hydrogen bonds, so it maintains its shape. Since molecules can't move past each other in this state, they are separated by the fixed distance of the length of hydrogen bonds. I think, anyway.
Why is the EU freedom of movement policy so rejected by the British, but so pushed by other EU member states?
I've often wondered if it's something to do with the number of EU migrants coming to Britain to work vs the number of British migrants going to EU countries to work. Does anyone have figures for this?
Why do I remember the lyrics to a song that I haven't heard since 1994, but I can't remember what I did a few days ago?
What you did five days ago didn't have a good beat, nor could you dance to it.
How do SSRI's work?
Serotonin is released from one brain cell to the next, the current belief is that more serotonin equals happier outlook. After the serotonin is released it is absorbed back into the brain cell that released it to be used again. SSRI's stop the serotonin from being absorbed back, meaning the brain cell receiving keeps receiving the same serotonin over and over. This means happier outlook. Selective really just means the drug affects serotonin releasers more than it affects dopamine or various other transmitters.
If the US believes in the separation of church and state, why does each political party reference 'God' so frequently?
political party isn't a government thing. You and your friends can start its own political party. There are many political parties. Just because there has been the same 2 largest ones for decades, does not mean others don't exist.
Why does paralysis occur? Why don't nerve cells regenerate and reconnect like other cells?
The reason is that central nerve cells are longer than other cells in the body and would need to reconnect in precisely the same way that they connected before. When you are born, the central nervous system grows as an interconnected unit. Once severed, the body has no mechanism to identify the correct neural path to make the right connection. Your body's healing is a local process that happens exclusively at the injury sight. It would be sort of like going to your breaker box in your house and cutting clean through all of the wires coming out of it, then trying to put them back together without checking to see where they go. Except in the nervous system a mistake might be worse than leaving it disconnected. There was never an evolutionary need to develop a mechanism since damage to the central nervous system almost always fatal to the organism.So the other comments seem to be from an evolutionary stand point here's the science part Nervous system: axons are myelinated individually with Schwann cells. Think of those "pigs in a blanket" hot dog bites. If an axon is damaged, the myelination grows back individually, and the axon is repaired. Central Nervous system : axons are myelinated with oligodendrocytes. Oligodendrocytes have a similar purpose as the Schwann cell EXPECT each oligodendrocyte is connected to and responsible for multiple axons. Once it is damaged, it cannot grow back by itself. Visualize this as an octopus, and each tentacle has an axon at the end, and once the octopus dies, the whole system is dead.
Why has France been targeted so often in terrorist attacks recently?
A large poorly integrated Muslim minority, many of whom live in Paris which is a badly run city in which the poor and immigrants are marginalised in the 'banlieu' suburbs. It's an environment that breeds resentment.
If nearly all the countries are in debt or in a financial crisis, where is all the money going?
I'm not going to claim I'm a financial genius who understands how all of this works, but I think this link holds the answer somewhere:_URL_2_
How can tineye find a single picture amongst billions in a second but a 5000 row VLOOKUP in Excel takes much longer?
There are a million ways to index random objects. Lets say you have a million images as files, and as /u/kentnl says, you could convert each one to a unique number. So then you have your target picture, and you convert that to a number. Lets say for your target picture, the first digit of the hash number is 7. Well you can discard all the other pictures that don't start with a 7. Should be about 90% that you can discard. From a million we are now down to 100k Take the second number in your target file hash and compare it to the second number in the rest of the files, should be able to discard another 90%, now we are down to 10Kand we repeat a couple more times and we are down to 100 files or less. Those four searches can be done by a powerful server in less than a second. Then you can start comparing the entire hash to the entire hash of the remaining hundred files to find any exact matches.
Why do vitamin pills smell so awful?
Because a lot of the compounds you're taking smell, or have to be stabilized or accompanied by compounds that smell. For instance, thiamine smells like sweat socks. Some multivitamins have hydrogen sulfide, which is a bit skunky or like a rotten egg. To contain the smells most multivitamins have a thin coating, but it's not going to be completely impermeable, it's only designed to shield you from the smell long enough to swallow. Sitting in the jar for a long time, however, the smells will permeate and collect until you open it and vent it. Also, as the pills get knocked around the coating can get chipped off.Biotin, thiamin , and selenium are usually in multivitamins. Sulphur compounds are rank even in tiny amounts.
Is there a reason most people always say they would save an animal over a person in an emergency situation?
I do not understand this behavior AT ALL. I would, in all circumstances, save the human and never the animal. But then again, I'm highly allergic to most animals and therefore have never formed a close bond with any pet mostly they are only going to poison me, so it's not difficult to choose the human even if they are kind of a dick.
Are there serious hurdles, specifically for Tech companies, that deter employers from facilitating Work From Home options?
Because your company had a 1980s vision of how their 21st century enterprise should function. The gains of WFH are tremendous. Increased quality of life from not commuting, annual fuel expense reduction, the comfort of being in one's home and not a staid office. I honestly believe that jobs requiring you to report to the office will be rare in 30 years. Interacting in person 2-3 times per month is sufficient to collaborate effectively with co-workers.
How come when you drive backwards, your car tends to feel like it swerves more when you turn the steering wheel then when you are driving forward?
The car feels more 'swervy' going backwards because you are behind the pivot point instead of in front of it. Also the inertia of rear steer is different on your body so you feel thrown around a bit too.
Why do hamsters enjoy running in wheels while other rodents (like rats and ferrets) do not?
My hamster is so lazy She will run on her wheel maybe a few hours in total per week.. And when putting her in her exercise ball she explores for only a minute before finding my feet and then just sits in her wheel waiting to be cuddled She is a perfectly healthy and young hamster so medical is not the reason It's just pure laziness. And then I grew up have 2 rats ..one whom loved her wheel, and the other hated it.. So my guess Each rodent has different likes and dislikes
How did World War 2 catalyze an economic surge in the US, but Afghanistan, Iraq and now possibly Syria put us further in debt?
The money spent and % of GDP was much higher in WWII. We're talking about $4 trillion in WWII spending compared to about $1 trillion. WWII spending counted for at least 35% of GDP* while post 9/11 wars amounted to just 1.2%, even if you include all of defense spending it is still only about 4-5%. So while the numbers thrown about with the wars costing us a ton, it is still a drop in the bucket. *GDP=The value of officially recognized goods/services produced by a country.
Why does uploading slow down my connection so much versus downloading?
It's like two pipes, You have a large pipe coming in that carries everything you are downloading and a small pipe going out that takes everything you upload. So because the D/L pipe is larger it can carry more data before it gets blocked up. However that small pipe can't take as much of a load so gets blocked up easier when you are trying to force a big file through it. This doesn't have to be the case though. You have 20/20 BB, which will give you as much up as down. Must will not provide you with this though and will provide something more a long 20/4, Here you have dl of 20mb and up of 4mb. You upload is going to get blocked quicker.As many people say your upload and download speeds are usually significantly lopsided. But if you have a provider like version fios you get 50/50 upload and download
What's in it for the people who keep uploading movies and software to torrent sites
The New Yorker wrote an article about something similar, it's called [The Man Who Broke the Music Business] It's about the early days of MP3 sharing, but it still relates to your question. If you don't want to read a long New Yorker article, the first half basically says that they're in these 'release groups' who go through enormous effort to get content ASAP, sometimes employing people from the inside to get stuff before release. Members who obtain top-level content are given a number of perks, such as priority access to other members' content, as well as acceptance and respect. And then there's a pride of inviting your friends over to play a video game that isn't even released or available on torrent sites yet. There's also competition among release groups to launch stuff as early as possible, again as a matter of pride. The second half of the article focuses on the eventual break up of the group and a court trial. I suggest reading the whole thing because the build-up to the last line is absolute gold, which I won't spoil here.the thing about "warez" is that the people who make games/movie/software available for free by removing the DRM from it, don't expect anything in return. they aren't in it for money . it's all about the free sharing of information, but corporate merica doesn't take kindly to the free sharing of information, so that's why words like "piracy" and "hacking" is spouted by the media whenever the topic is brought up. What happens in Somalia is ACTUAL piracy; the free sharing of information isn't.
Why don't women's pants have functional pockets?
And now I have this gigantic Samsung it's even more difficult to find jeans that fit my phone in.
why is it we can we send a robot outside of our solar system, and exploring the surface of an entirely different planet, but the deepest oceans are unknown to us?
No one has ever sent a probe to a planet outside of our Solar System. They've only been looked at through telescopes. Probes have been sent to planets in our solar system. Things don't have to be that strong to withstand 1 less atmospheric pressure. They do have to be strong to withstand the absolute crushing pressure of the bottom of the ocean.
Why can't commercial airplanes deploy Parachutes for use in case of emergency landings where all other manoeuvres or options to save the plane have failed?
It's not economical. For the 99.999 percent of flights where it's not needed it would cost the airline money to be there since it would add drag and weight that could be used for passengers instead. It sucks but it's not an option. There will always be aviation accidents and the industry does what it can to reduce them but remember there are thousands of flights each day that land normally. Your fate would be astronomical if the airlines added all the ideas thrown out . Planes are pretty damn safe.
If we are counting years from the birth of Christ then why is birth of Christ(Christmas) every December 25th instead of last day of the month
The idea of counting years since the birth of christ didn't show up until around the 6th century, and it didn't change the days and months of the existing julian calendar, which had been in use for nearly 600 years at that point.
The difference between polygons and voxels
Object made out of polygons is like a papercraft, basically hollow inside and made out of flat surfaces. In order for computer to calculate such an object, it just needs to know where points/corners of these surfaces are and how they are connected. A game character may have a couple thousands of these points. The coolest thing about it is that you can paint over them, adding detail where geometry just isn't enough. Object made out of voxels is like an object made out of LEGO. You need a lot of them, a lot of a lot to make character that doesn't look like made out of blocks. That means computer needs to calculate a lot of points and how they interact together, how bright/shaded they are ect. Also painting over them would be a bitch. In papercraft you can simply paint an eye on a surface, with voxels you would have to arrange differently coloured LEGOs.voxels are like polyhedra, that is they are 3-d
How are houses investments? It seems like they're just more expensive all around than renting.
It's worth noting that when studied properly, homes historically appreciated at [just 0.7%] per year, adjusted for inflation. When your grandparents bought a house in 1960 for $40,000 and it sold for $300,000 in 2000, a lot of that was just ordinary inflation $40,000 in 1960 had the spending power of $232,000 in 2000. We do a lot of funny math about home appreciation. If you bought a house for $300k and did a $70k in remodels and $30k in repairs, then sold it for $450k in 6 years it's a bit unfair to claim that as a $150k profit . It's really more like $50k, or 16.6%, which is barely beating inflation over 6 years. When you look at a house that hasn't been invested in at all over many years, it rarely has actually gone up drastically in sale value. Usually it's the kind of house that needs a lot of work, or it will just sell for a paltry amount to house flippers.
Why is the windows task manager able to close programs almost instantly while right clicking to close a program on taskbar doesn't?
I like to go to Windows command line and execute TASKKILL. It's sort of like playing a DOS version of Assassin's Creed.
Why are certain human senses more prone to annoyance than others? I.e. hearing the same thing over and over is annoying, while seeing the same thing over and over is not
Well I've got a test for you. Don't pay for Direct TV access on a three hour United flight and watch their promotion bullshit loop the whole time. I could turn the screen off directly in front of me, but nearly every other screen I could see was on the loop. It was maddening. And to be honest, since I didn't have headphones plugged in, it was even more annoying because I didn't have the additional context. I would have agreed with you, but when looking away really isn't that easy, trust me, it's annoying.
Solar Cell Electricity, where does it go when the battery is full.
Kind of disappointed nobody has mentioned a load dump device yet. It describes exactly what you're talking about. we don't see it so much on the solar end, but for wind power generation it sure does. Especially during long windy stretches and you're not using as much as you're generating. _URL_0_ I've heard of people using large HPS on small scale wind although not ideal. But I believe the water heater variant is pretty common up here for people with boilers. usually off grid running their boilers off nat. gas/lp/oil. You don't really notice, other than you just happen to run more efficiently on the boiler side.
How can Netflix instantly stream very high quality/HD content but other online video players require significant buffering and much longer load times?
Really what it boils down to is that Netflix has a much larger network of servers to accommodate for the traffic. Wherever you are located, when you begin to play a title it will pick the closest server to you that has the content stored on it, and you will download the data straight from that particular server. So let's say you play an episode of Family Guy, but the closest Netflix server to you doesn't have that title - it will try the next closest server, and so on. This way, you don't have everyone in a particular country drawing from the same server, so it cuts down on bandwidth and allows for a more streamlined experience. Other online video players it depends on who you're talking about, but the less legit they are the less servers they have available for you to stream from, which results in many more people pulling from the same server, and there is a good chance it is located far away from you. Most pirate sites use servers that are overseas and privately hosted, so you don't have much of a range to download the content from. Aside from that, services like Netflix generally have more powerful servers that allow you to pre-load things as soon as it knows what title you're looking for, as well as load a lower quality version of said title so you get you content quicker. As you watch the title, the quality improves as it starts downloading the higher quality image. There are other features companies like Netflix have along this realm, but the big thing is really the quality of the server, the bandwidth allowance, and the location. Source: I'm an investigator for an anti-piracy organization.
Why do fountain drinks at different restaurants taste different?
Most restaurants rarely clean their syrup lines. I'm a refrigeration guy and many of the restaurants I've been in are frankly disgusting.
How could it be that American schools are second-rate, but American higher education is the best in the world?
Professor here. Much of the discrepancy lay in two complementary factors. The first is obviously money. K-12 schools are taxpayer funded . This means that the funding is going to have a politically tolerable cap, determined primarily through what people are willing to pay in homeowners taxes . There is no competition for the most part, so schools become slow, ponderous and underfunded. The political and administrative burdens placed on classroom teachers are borderline intolerable. The opposite is true for most colleges: with the severe decrease in state funding, colleges generate income through tuition, grants, and endowments. This creates a marketplace competition that forces prices down and quality up. On top of that, the quality of teachers are shockingly different. In some states, teachers only have to score in the bottom 20% of teacher exams; for tenure track faculty positions, it's not unusual to have dozens or sometimes hundreds of applicants for one position, so we hire world-class academicians for reasonable prices. On top of all that, there's a self-selection bias. College is expensive and not required in the US, so only people who want more education are going to sacrifice the time and money to learn more about the world. K-12 is largely mandatory, so you've got a larger distribution of abilities. The better the student, the better the outcome, no matter how the quality of teaching stacks up.
Why is CPU development slowed to a crawl? What is the next "hurdle" in CPU innovation that needs to be overcome?
Physics. Both processor speed and transistor size are edging towards physical limits - transistors are so small that there are too few atoms in them for them to work correctly, and clock speeds are so high that signals - at speeds close to the speed of light - can't move far enough before the next clock cycles hits. We are mostly working around those constraints, but there's only so far the work-arounds can take you. There's also Intel's monopoly. When you are pretty much the only company producing computer CPUs, there's no incentive to improve. Expect to see things start to happen now AMD has released there quite impressive Ryzen range.
How do drug addicts stop being drug addicts? Why can some people do it and others can't?
well not everyone who uses drugs is an addict. in fact i smoke poke and i enjoy it when it snows. but, I can totally stop whenever I want. It's all about self control. Someone who eat McDonald's every 3 days while not working out is some how the good guy. Yet, I'm lifting everyday, eating a kale salad and enjoying some powder, somehow I'm destroying myself? Don't get me wrong drugs do have their negative effects. You must practice self restraint and be self motivated not to get stuck in a hole. Enjoy the benders but remember to come back.
What is happening when we feel someone/something staring at us?
Confirmation bias. You forget all the times you look and no one is staring because that isn't interesting, but turning and seeing someone stare is a 'big event' to you once you think you 'feel someone looking at you' so your brain likes it more. Also as you turn your head if there was anyone looking in your general direction they will be more likely to look at you.
Why doesn't the one dollar US bill have no details to help determine if it's a counterfeit?
The time and effort that goes into counterfeiting $1 bills make it incredibly unprofitable to do so. You'd be better off counterfeiting higher denominations or committing another type of monetary fraud.Well it does. It is on rag paper, uses special ink, and does have printed security patterns on it.
What is 'octane' in fuel and how does it make your vehicle preform better or worse?
ELI5: This is one of the few areas in which you can use the word retard and be politically correct. Higher octane fuel has a higher resistance to detonation meaning you can jam pack the combustion chamber full of fuel and oxygen - it doesn't want to explode. You can take advantage of this by retarding the timing of the spark to maximize power output. I hope that was ELI5.
can your hair really turn grey from stress? and how?
When I was 22 I lost my 3 year old son, and a gray patch appeared within 10 days. Still got the skunk patch to this day. I'm 34 now.
why I'm not bald despite the fact that I lose about twenty strands of hair in the shower a day?
In the last year I've gone almost completely bald due to alopecia. Trust me, if your hair was falling out in a serious way it would be in gobs . At the peak of my hair loss I could clean out the drain twice per shower, and remove as much hair as I might normally remove in a month.
Why strong, muscular animals such as gorillas don't need to lift weights to build a ton of muscle mass but humans do?
It's partly due to genetics, the fact that gorillas are as big as they are requires them to have a lot of muscle just to move themselves, and so their body's homeostasis will work to maintain that muscle mass to an extent. But it is also lifestyle, being an animal in the wild is tough, and you have to work for every bit of food you eat. So part of the reason they are so muscular is the same reason why longshoremen 80 years ago were super muscular or farmers or railway workers or any other trade that requires manual labor. Working your muscles builds them up.Gorillas DO lifts weights. They climb trees all day. Effectively doing pull ups constantly. And when they rough house, they do it with other gorillas who are HUGE.Too be fair, while not that muscular, humans were probably pretty jacked back in the day. Scientists correct ke if I'm wrong, but I'm sure that pre-civilization humans were probably in mostly good shape. Now that we have a culture of sitting down and relaxation without the worry of predators, things have changed.
Is the sound of wind caused by the wind hitting things? Or the wind hitting its own particles? Or something else entirely?
It is friction my friend. Air is very good at making sounds through friction, take your mouth for example: most of the sounds you make when you speak are through friction between air and a part of your mouth. The sound 'th' as in 'thought' is called a voiceless dental fricative as it is made because of the friction between your tongue and your front teeth. So on a larger scale with fast winds the friction is inevitable.
Why do Third World Countries have problems with possessing water, when the earth is 79% of it and we have the technology to purify water?
Water treatment is very expensive in the modern world , and the sheer scale of the problem is astronomical, with much higher populations than say 150 years ago when much of the developed world's treatment systems started. If you are thinking specifically about South Africa right now, there are some specific factors are play. Cities get water from many different places, but mostly its rivers, it is just a matter of what is the source of the river, and how much do they dam it up to store. Johannesburg has been in a drought for a couple of years, so historically they have had rivers feed reservoirs then the reservoirs supply the city and I am guessing the waste is down stream. But you can only store so much in a reservoir, and they have run out. Consider the issue of sheer numbers. If you have some river and 10 people live along it you need relatively little treatment. 10 million, or 100 million and you have a problem. Add in industrial runoff rather than just human waste and its very hard to clean the water at all.
Why don't I stutter when I'm alone?
I've read that children learning to read have an easier time reading when they practice in front of their dogs or cats. I'd be interested to know if a similar principal could apply with you? Maybe you can try speaking in front of a dog and then graduate to 1 person followed by a group of people . have you thought of that?
Why do numbers to the power of 0 always become 1?
An additional way to see the same thing Speaking casually, the exponent in, say, 5^4 tells us how many times we're multiplying 5, right? OK, then 5^1 ought to be what we get if we multiply exactly one 5. But multiplication is what's called a binary operation , so multiply that single 5 by **what**? Well, by the thing *t* such that 5 & times; *t* = 5, in other words by 1. Fine, so for any integer *n*, the expression 5^*n* should mean the product 1 & times; 5 & times; & times; 5, where there are exactly *n* multiplications by 5. Thus when *n* = 0, you get 5^0 = 1.
Why are the latest phones upwards of $700-$800, while the latest tablets are only around $200-$300
I think you are overgeneralizing a bit, there are definitely tablets out there that can cost just as much as a phone. It all depends on what features each product has. An iphone with hundreds of gigs of storage it definitely going to cost more than some off-brand tablet with only 32 gb of storage. Likewise you can also find cheaper phones out there compared to more high end tablets. But lets say, for the sake of argument, your generalization is true. It could easily be explalined by supply and demand. Cell phone have a much larger user base than tablets, pretty much everyone owns a cell phone. This isn't as true for tablets. So the price would be higher based upon the higher demand.
Why are there so few engineers and scientists in politics?
I work in politics, my two best friends are mechanical engineers. My friends are both extremely intelligent, but their type of intelligence doesn't translate well into things that aren't black and white. The know that the table needs to hold x amount of weight, so they know that the legs should be y strength. Politics deals largely in philosophical ideas. A number of the things we might want have never been implemented before, or that way. I work specifically in campaigns, so I deal a lot with emotional appeals. See the [Willie Horton Ad], or [LBJ's 'Daisy' Ad]. Much of my job requires charisma and charm. I have to sweet talk people with big egos and media types. Yeah, there is science to it, but it's not cut and dry. When I talk politics with them, they get frustrated because something seems so obvious to them and they don't get why everyone else doesn't just do it.As an engineer, I would rather work on engineering problems than be embroiled in the drama of politics. I think that, in general, people who put in the time to become experts in STEM areas are more interested in doing STEM-related work than in government. People who major in, say, political science probably want to be in politics.That's like asking why are there no doctors driving taxis.
How these type of walls stay intact when sea levels react the top.
The pressure of a liquid at a given depth depends *only* on that depth, not the total volume of liquid. Which means that whether it's holding back a swimming pool or an ocean, a wall holding back a liquid at rest only has to be designed to handle the pressure at a given depth. A ten-foot wall only has to be built to hold back the pressure given by a ten-foot column of water. Maybe more, because you want to be able to deal with the force of waves and moving water. But the bottom line is that whether you rope off a small section of wall and pour a swimming pool's worth of water against it, or the whole ocean against it, the force it takes is only related to the height of the water column it's holding back.
Why is it so hard for tinkerers to use parts of consumer electronics (smartphone cameras, etc) for their projects?
Even if they aren't using fragile SMDs, the process of removing components can damage them if you aren't careful. The heat can damage semiconductors in particular. Passive components like resistors and capacitors not so much, but these components are so cheap anyway that it's not a priority.We live in an age where building something new often costs less time, money, and effort, than re-purposing old parts. To make something out of spare parts these days only happens out of necessity, where access to new materials is more costly or time consuming.
How do we know for sure that cancer and other deceases aren't caused by being constantly exposed to small radiations from electronic devices and 3G, 4G, WiFi, LTE, Bluetooth-signals?
A danish study over 20 years, found absolutely no correlation between cellphone usage and cancer rates. Other long-term studies came to the same conclusion, and even cellphone network towers have never been seriously linked to cancer rates. Here's a few results from long term studies: _URL_0_ Which concurs which what other posters here said, that RF waves simply aren't strong enough to change or break DNA.
Why most Canadians seem to dislike French Canadians
1. Biligualism can be a pain, especially in western Canada where there aren't many French speakers2. They have a double standard when it comes to bilingualism they want the rest of Canada to speak both French and English, but try to have as little English as possible in Quebec3. French Canadians often appear to act as though French speakers first and Candians second4. Similarly, Bloc Quebecois is a national political party looking out for the interests of Quebec no one else puts province over country like this5. Bloc Quebecois is often in a position to break ties in parliment, but demands concessions for Quebec in order to do so.6. There have been two referenda for Quebec to succeed from Canada
Why do Men and Women have different size numbers for the same size article of clothing? Why not let them be the same?
IDK about clothing but for shoes, women's feet are narrower relative to the length compared to men's feet
How can somebody like Tom Cruise be so successful in life and yet simultaneously come across as a complete nut?
Acting is not a profession in which you need to be sane to achieve success. In fact, you don't even need to be intelligent, or good at it. Just look at the Kardashians. Or Shia LaBeouf.
/ What is color?
The atom is the smallest part of matter that still retains its physical properties . So yeah, if you get any fixed amount of gold atoms only, it will always be golden; the same golden. Since most objects are not made of single kinds of atoms, but substances, we have to think about the color of the molecule that composes that object. But since almost nothing is made of a single kind of molecule, we have to think about the product of that heterogeneity. That's why macroscopically, gold may be of different colors. Because it's not pure.
As a Non-American, why the hate for Obama and what he's done?
The last time I checked the president's current approval rating is 44%. This is low when compared to other presidents at this point in their administration but it also means that those who disapprove only make up 56%. Not that big of a gap. The reason he is perceived as being so hated is largely based on human nature. People generally complain much louder than they praise, and are more apt to make their opinions heard if they are unhappy. He has done some unpopular things, yes, and more people are unhappy with him than are pleased. But American politics are so polarized right now due to how extremely opposed the major parties are that this would be the case with any president trying to push for any meaningful change.People have a huge misconception that the PotUS actually has any power. The President can only do so much and there requires a lot of coordination between the Senate and House to actually accomplish anything', "I'd consider myself mostly neutral and ambivalent. The liberal crowd feels like he isn't liberal enough, while conservatives think he's too liberal. He's seen as a hypocrite by both. And the ACA isn't actually free health care- that's why there's an issue, for the most part. Instead of being government-supplied healthcare, it's more like government-mandated healthcare you still have to purchase. If you don't, then there's a fine that costs more than the healthcare would. And as for the whole communist Muslim thing, that's mostly just the *radical* conservatives being racist and extremely reactive to liberal ideas. No one really listens to what they have to say, they're just really loud about it.
Nutritional Supplements, what should i be ingesting and what is purely hype?
Creatine. It actually works. You'll notice you'll get a bit more out of your workouts and it'll help w/ recovery as well. It's also relatively harmless as long as you stay hydrated. The only real noticeable 'downside' in my experience is putting on extra water weight. Not really a big deal unless you're trying to make weight for a competition or those numbers on the scale just mean A LOT to you for some reason. Anyway, this page will explain it in-depth. _URL_0_
Ancient Warfare - why did we regress?
I think economics is a big factor as well. Standing professional armies are very expensive to train and supply. As Rome declines and disappears, the new rulers of Europe find it becomes too expensive to pay for the training and equipment of a standing army that requires wages paid to it and a constant stream of food and other supplies. It becomes much easier to organize forces only in times of war, have these soldiers supply their own equipment, and only campaign during seasons where foraging is possible to sustain your army. Also, don't forget that the Eastern Roman Empire did not decline with the Western Empire, the Eastern army continued its professional status and continued making advancements and bettering itself.
Is there a technical reason why in America tax is added to the final price as oppose to being included in the final amount?
A few reasons. * Some customers may waive the taxes, e.g. another business purchasing for resale. They'll pay the sticker price, no tax added.* It's marketing, just like gas stations that price gasoline to a fraction of a penny. Nobody wants to be the first to show a higher price than they have to.* Convenience of pricing, since the register can add the tax automatically. If the tax changes you only need to adjust the register, not reprice everything in the store.
I have multiple pairs of Levi's 513s, 33W 30L. Why are every single one of them completely different?
As others have said, it's just poor quality control. They could make them more uniform, but they would cost more money.
How come the Europeans advanced faster technologically than the Native Americans/ Africans?
One thing that is being ignored here is that Native Americans actually had their own technologies developed independent of Europeans. For example, there is evidence that Native Americans modified the landscape on a massive scale. [Here] is an article containing some of that evidence. Charles C. Mann's *1491* goes into a great amount of detail about how indigenous people actually had history and technology before the arrival of Europeans. According to Mann, popular perceptions of Native American cultures prior to Columbus's arrival are incorrect--the reason Native American cultures seemed primitive to early Europeans is that disease preceded the arrival of all but the earliest Europeans, so the primitive cultures that Europeans saw were actually disease ravished skeletons of civilizations.
Why does water feel much colder/warmer at the same temperatures as air?
Water has a high specific heat . this means that it requires a large of amount of energy to raise the temperature of water, but something like gasoline requires very little energy to raise the temperature. so if you have a bathtub full of hot water it will be hotter for longer than a bathtub of hot gasoline. if you had a tub of cold water it would require very large amounts of heat to warm the water up, so if the air went from freezing to hot during the day, the water would warm up a little but wouldn't get enough heat to make the water any warmer. thats why it takes months for lakes and ponds to warm up after the winter months because, it requires so much energy to heat water up. some youtube education_URL_0_ _URL_1_
What effect does the curvature of the Earth have on really large buildings, roads and other infrastructure?
Earth's curvature changes its height, on average, 11cm per km. This is far, far less than natural local variations in terrain. Therefore it has no effect on people making buildings.For some structures you have to take this into account. If something is both very high and very long, it becomes a factor. Suspension bridges often fit this bill. The Verrazano–Narrows Bridge in NYC was designed to account for the 1-5/8" difference in the distance between the top of the top of the towers and their foundations.
What happens when a state passes a law that contradicts with the Constitution in the United States?
I think the key thing to understand is that someone must claim damages and file a suit. The states can make any law they want to no matter how unconstitutional. But if they do, someone will file a lawsuit claiming damages which if nesc can be taken all the way up to the supreme court who decides on the constitutionality if it hasn't already been done. This was the case not too long ago with gay marriage. California made laws that prevented same sex couples from getting married. Some couples claimed damages from not having the same rights as everyone else. It went to the Supreme court who rules those California laws unconstitutional.
How do programs that are not for commercial use detect that they are in fact being used for commercial purposes?
It depends on the program. Some programs impose arbitrary limits that would be unlikely to effect personal use , but would with commercial use others use watermarking to 'spoil' the files on non commercial/student versions A lot though, simply rely on honesty, or only offering differing levels of support and access to updates.
Why are there "Morning People" and "Night People?" What makes somebody operate better in the morning as opposed to in the evening?
I'm going to assume it's something to do with daily routines and sleep patterns.Read somewhere that genetics may play a part in this.
Bernie Sanders wants to 'break up' the big 6 corporations on Wall Street.... What does this actually mean?
Specifically he wants to break up the 6 biggest banks in the United States. While there a a lot of good arguments on both sides of the discussion, Sanders' drive is to avoid future 'too big to fail' situations like the ones that occurred in 2008/2009.
How was bread stored throughout most of history without it going bad? Was stale bread just the norm?
First, the crust is pretty much designed to keep the bread fresh. It seals in the moisture. You'd get a bunch of small loaves and those would keep for a bit without going *too* stale. You'd generally finish eating a loaf fairly quickly. And if it went stale, you ate stale bread.
Why are minorities likely to see the majority(read: white people) attractive but no so much the other way around?
In the magazines and on TV, the goddesses we're presented with as these fountains of beauty are virtually all white. Racism and exclusion pervades mass culture. This tendency to find whites more attractive is taught.
The act of cutting a piece of paper or any other material. How does it work on the microscopic/atomic level?
The simplest explanation I can come up with is that your cutting tool comes in between intermolecular forces holding the material intact. In your example, your scissors force an edge in between hydrogen bonds, causing the bonds move farther apart, which after some distance reduces the probability of their affecting each other to pretty much 0. Some materials are sharper than others because they expose an edge that isn't as wide. Of course, they're more brittle for basically the same reasons . Disclaimer: Not an expert.Question: if you do cut paper, why does not lead to the edges breaking the chain and lead to a new compound along the edges?Basically the pressure that you apply with scissors or knife is stronger than the bonds between molecules, so they just break apart. Imagine squeezing some lego bricks quite hard and how they would split off even though they are stuck together to begin withIn some sense, you are kind of asking how material hold together in the first place. For paper and many other things you might commonly cut, there are long-chain molecules held together by intermolecular forces. The manufacturing techniques take fairly weak materials and repeatedly join them together by further intermolecular forces, into very strong materials. [That is, there are a number of layers by which the long-chain molecules combine to make fibers.] When cutting, you are penetrating a large number of these individually weak forces.Warning, dated references. Much like a single pair of headphones, paper is made of thousands of strings we call fibers. Instead of unweaving these headphone-like strings for the next week, scissors press the fibers in opposite directions to break apart at a much faster rate. Sometimes when the scissors do not line up properly, the paper's fibers resist being broken apart. The sharper the scissors, the closer the press is to each other- making a clean cut more molecular than just ripping the paper.
If I have an electrical circuit, run a current through it, and then suddenly interrupt the circuit, what happens to the electricity still within the circuit?
If you are talking about a simple circuit, the simple answer is nothing happens to it, it just stops flowing. Electricity is the flow of electrons. Voltage is how hard the electrons are being pushed. When you apply voltage to an electron it moves. This movement is what is referred to as electricity. When you interrupt the circuit it no longer has anywhere to go, so it stops moving. It's like when you turn your water off at a sink, the water is still in the pipes, but now that you've closed the valve, the water has no where to go so it stops moving.
Feelings/ urges experienced during menstrual period
It just sucks, really. Every woman has a different experience but I know for me and my friends the PMS that occurs the week before is the worse. The hunger is extreme, no matter what I eat, I'm still hungry and I am completely not in control of my emotions and feel fat and ugly. This usually only lasts a day, but it is a very terrible day. The cramps are more of a constant lower back pain, and just a general feeling of being in mild-moderate pain and incredibly uncomfortable. Again, this only lasts a few days and the rest of the week is fine and so is the next few weeks until the PMS begins again the next month.
Could you, in theory, build a giant artillery gun with the range of an ICBM?
Yes, in theory. [Gerald Bull] was a researcher and engineer who tried to develop Nazi Germany's [V-3 cannon] into a full-fledged satellite launch system. He was best known for his work on the US/Canadian Project HARP and for Iraq's Project Babylon.
Why do plastic milk jugs always have gross little dried flakes of milk crust around the edge of the cap? No other containers of liquid (including milk-based ones) seem to have this problem.
the jug design matters. kwik trip used to use nicer, higher quality design that minimized the milk that got 'stuck' to the top that causes the stinky dried milk. but they changed to a cheaper design, similar to that used by most other dairies, a few years ago.
why is it that long distance shooters tend to use bolt action rifles? Can a magazine fed semi-auto not do the same job?
The long and short of it is that semi automatics use bullet energy to re-cock and expend the spent casing, they have more moving parts, and this makes it more difficult to have the same tolerances as well as changing consistency from shot to shot. Bolt action is simpler, easier to make with precision, and very consistent. The accuracy of a rifle comes down to consistency and precision. Precision means that all of the parts fit together with very close tolerances and with a minimum amount of slop or wiggle. The more mechanically complex a rifle is, the harder it is to make each part with precision. It's not impossible to create a semi automatic rifle with accuracy but it is difficult and expensive, and as parts wear it can change. Consistency means that each time a cartridge is chambered, fired, and ejected, it is done the same way. All rifles must warm up with a few cold shots first but after the initial shot a good rifle will do this predictably. What you don't want is for things to change in an unpredictable way from shot to shot. Part of this is the design of the rifle, how heavy it is, how tight the tolerances, and how it deals with heat. The other part of this is the ammunition, whether the grain count is reliable and each round fires like the other rounds. Bolt action rifles push the range and consistency out to the edge from precision parts, a predictable cold vs hot bore shot, and the bolt mechanism is robust, easy to clean, and simple. You want a minimum amount of factors that can affect the shot so it's more predictable and a simpler mechanism reduces these factors. Semiautomatic rifles of today can meet or exceed the range of bolt action rifles of yesterday, but they are more finicky and more prone to drift as the different parts wear out, and cleaning is much more important as the gas pressure must re-cock the firing mechanism and expend the spent casing. This takes energy from the bullet and also changes from shot to shot with environment and how clean it is.
Why is it said that Florida, Arizona, and Nevada could only grow with air conditioning when many of history's great cities flourished in similar climates long before the invention of A/C?
While Singapore largely developed in it's early days because of its strategic location as a trading hub for SE Asia it is interesting to note that its former President - Lee Kuan Yew hailed the Air-Conditioner as one of mankind's great inventions and credits it with helping to propel GDP growth from the 1960's when it was first introduced by increasing efficiency in the public and private sector. Singapore GDP growth averaged over 7% from the 60's and helped Singapore change from a developing to highly advanced economy over a short period of time. You could argue Air-Conditioning helped play a part in this. Lee himself liked to live his entire waking life at 22C reduced to 19C at night while sleeping.
How did people decide on seconds/minutes/hours? How the heck do we even know how long a 'second' is?
1 second used to be defined as 1/86400th of a day -all of these numbers have a relatively high number of factors and are easily divisible into segments, or periods of time. If I remember correctly I think the French were looking at using a decimal system for time a couple of hundred years ago. I believe a day of 10 hours made up of 100 minutes of 100 seconds was proposed . Which as mentioned in another post, isn't as easily divisible. On a slight tangent the most accurate clocks nowadays take a second to be roughly 9 000 000 000 vibrations of a Caesium atom-hence the atomic clock.
Why does it cost upwards of $50 to ship from USA to Australia, yet I can get the same thing from Amazon with $10 shipping.
I make and ship things to Australia regularly. The cost hike for smaller guys like me is due to the fact that we are covering the cost of the discounts that bigger shippers like Amazon are enjoying. It's also a lack of consumer oversight and protection. Even the price of shipping supplies in the US is ridiculous. There are a few manufacturers left for things like bubble wrap and the like and they gouge you for it and there doesn't seem to be a way to get around it for a small operation like mine without a hefty investment in alternative packaging machines. I'm constantly running into supply issues due to the fact of past mergers of larger companies have erased the competition and now operate like a monopoly. At this phase it really is a monopoly. On top of all that you have UPS and Fedex trying to end USPS and lawmakers are backing them up with straddling USPS with nearly impossible financial demands for its retirees. The same thing is going on in Canada. I do expect to pay more to ship but not 5x more than a larger corporation. And it's not due to bulk shipping because shipping is a regular occurrence with metrics that can be tracked. Currently I take a few dollar hit for every international order I fulfill to try and save them some money. Transit times are also becoming less reliable. It's a mess. I can order something from China via airmail for less than I could ship it to a US destination form within the US.
Why Can't We Clone Dinosaurs?
It's tricky to get DNA of an extinct specie before the DNA catalogues. Let's use Dodo bird as an example. Even with the best preserved Dodo-bird , the DNA is still unusable. If we can get pass the degraded DNA issues, there are still a major problem with finding a compatible surrogate mother.
How can medical studies with very small sample sizes be deemed as credible?
It depends on the question you are asking and the rigor of your controls. A very rigorously controlled study can get pretty good results IF you ask the right question. I've worked in drug and device research, and Small studies are usually enough to get an idea of a safe drug dose, look at whether it seems to work well enough to keep studying, or maybe test some new device where the changes from existing technology aren't that great. As littleelf says, too, for rare diseases, smaller samples may be deemed acceptable because there's no practical way to test in larger groups.
How/why there is a difference between 4/4 time and 2/2 time in music
Hey guys, I've struggled with time signatures for years, I just don't understand them. It's like some weird mental barrier keeping me from understanding. So explanations that are *literally* aimed at a five year old would be great for me. Edit: thanks for the explanations guys. I'm reading them all but am now too drunk to respond coherently so here's your en masse gratitude.This thread is comedy gold! The OP is drunk and has very little understanding of music notation and simply cannot grasp the concept. And the responders are seemingly all trained musicians trying and failing to explain what is a completely elementary concept.I'm not a music pro, but I've always learned that in 2/2 the first beat is accentuated, the second is not. In 4/4 the first is also accentuated, the second is not and then the third is also accentuated, the fourth. BUT the third is not as strongly accentuated as the first is. This gives another feel than just 2x 2/2. Am I wrong or does this sound reasonable too?
how come that one asteroid killed all the dinosaurs all over the planet? and how didn't it destroy the earth with it?
_URL_2_ The wiki page is pretty good. The basic answer is that it killed lots of things, not just non-avian dinosaurs, mostly through secondary effects of the impact . it wasn't nearly big enough to destroy the planet itself, but it made the planet inhospitable for a few years, enough to all but wipe out the largest dinosaurs.
Why do Brits use mix between imperial and metric systems, and not just stick to one?
Metric is great for scientists. It's all power-of-tens and the measurements dovetail into each other well So, it's easy to use, and easy to convert. But, for the rest of us non-scientists, it's more convenient to have a measurement system based on 'real-world' things. Even if they are somewhat approximate. Like the length of a foot , or the distance from nose to the tips of your fingers , or 1000 walking paces , or the volume of two cupped hands . Other measures are based on halving/doubling. 1 Gallon = 2 half gallons = 4 quarts = 8 pints = 16 cups. Makes dividing easy- just split it in half. So, metric for scientists, and 'Imperial' for the rest of us. :-)", 'Same in America my friend. Excerpt from an article about it:"A football field traffics in yards while most footraces prefer meters. Mechanics measure the power of an automobile engine in horsepower , but express the same engine's displacement in liters. Air pressure is denoted in all sorts of ways: pounds per square inch for tire pressure, inches of mercury for surface atmospheric pressure and millibars for air pressure aloft."I think most of us are getting better at being able to work in both. I can use feet and inches and metres and centimetres comfortably, lbs and kilos is quite simple to work out , as is miles and kilometres . However with fluids I work in litres, have no idea about oz/ gallons, apart from MPG.Traditionalism, probably. We even used [alcohol proof] until the 80s. We use miles, and measure heights in feet and inches, and sometimes weight in stones although I still like to think that we're better with using the metric system than the Americans. Give us that, at least ;)
Why is going to the cinema considered a social experience? You're expected to sit in silence until it ends.
I don't think it is. I go to the movies by myself all the time. I arrive right before the movie starts, usually right when the lights go down. It's incredibly easy to find a single seat, and no one even knows you're there by yourself, they're already watching the screen. When the movie's over most people head straight to their car. It's actually incredibly hassle free and a better experience than going with friends.
how/why imgur became the defacto image hosting service for reddit.
Alright then guys, I know why Imgur became popular for reddit, why isn't it popular elsewhere?", 'Because _URL_1_ went to shit with their uploading system and how they restricted uses.> I'm pretty new to reddit Redditor for two years.Damn. Every single answer here is missing one of the KEY reasons. Front page links/pictures would crash many websites. The comments would be full of frantic hunts for mirrors. Imgur was the de facto mirror of choice. Then, everyone just stopped bothering with the original website and loaded it into imgur first.I'm surprised nobody brought up the conspiracy theory that reddit owns imgur and uses it as another source of ad revenue so they give it priority on reddit. .Because the person behind it is a redditor.We trust that person more than an outsider.It's free and has always been pretty reliable. It grew from there and based on those factors, and others mentioned elsewhere in this thread. Other image hosts have cropped up here and there that reddit seems to accept. Included among those is _URL_2_ .
How has the Student Loan bubble not popped?
Mainly because student loans stick with you forever, you can't use bankruptcy to get out of them. They will always be there .
Why does the NRA wield so much power?
They don't. Jimmy Kimmel is lying and has politicized a tragedy before the blood's dried. Imagine that.
How can hospitals charge as much as they do?
In addition to the high costs issue and the captive market issue, another issue is actually the reliance on health insurance. Hospitals can't charge ordinary people hundreds of thousands of dollars for surgeries; people simply don't have that cash. But large insurance companies do. By going through the middle man , it makes it easier for hospitals to charge significantly higher prices than they otherwise could as the final cost ends up being dispersed among the entire base of insurance customers. Proof you ask? Well anecdotally, I've seen multiple cases on reddit where hospitals quickly negotiate down their prices when the invoice is going to an actual person and not an insurance company . Healthcare is also one of those complex areas where price is often taken as an indicator of quality, and seeing as no-one wants their lives in the hands of the cheapest doctor available, the normal demand law does not apply. I have only a very, very basic grasp of economics, so any econ major is free to correct me on this.That capitalism for you. In the UK, we had a socialist government after WW2 who brought in the welfare state, free; health care, education, school meals etc. Meaning even you had no money at all you could still be healthy and educated. The down side is we pay a lot more tax than you guys.That is so ridiculous. I knew of a girl Who was hospitalized for about a month before she passed away, and just to add to the burden her family received a bill that was close to $1,000,000 for the treatment. It's so awful.
Why do people key cars?
Well, it's a beautiful, expensive car. There are a lot of people who spite those who can afford the luxuries in life that they themselves can't. So, they key your car because of that.
Why are some people so prone to cavities?
Oh, I have personal experience here! There are a number of reasons that one can be prone. In my case, my jaw is small and compacted. It's really hard to get everything out and my teether are together tightly enough that I can shear most floss through normal usage. Grinding teeth in your sleep can also be a problem. I had to get a bite guard and thats helped reduce the number of cavities I get.Low mouth pH is the cause of cavities but there are a lot of factors that affect this. Diet , frequency of eating, medication being taken , genetics, and the dominate flora of bacteria in your mouth. Bruxism and acid reflux can also play a role.Brushing, flossing, etc are only part of the equation. Your diet is also part of the health of your teeth.
