Can you explain [LI5] why Marijuana is illegal? | There is a good body of evidence that the motivation is actually the clothing industry. See, Hemp is actually a really strong, durable material. Shirts made from the stuff literally last decades. During the earlier part of the 20th century there were strong lobbying from the nylon industry about this, in particular from Du Pont. Even though hemp isn't marijuanna *per se* it is part of the plant, and so the whole thing has to go. |
How did warfare work in the 1500-1700s? | Army size increased by a lot, because having a huge infantry became much more useful in volleys and such. And logistics wasn't quite there yet, so these huge armies would essentially raze the surrounding countryside for food and supplies. That pushes out the civilian population and makes guerilla warfare less practical, since you can't hide among nearby civilian populations in between attacks. Good infrastructure didn't really exist, and what did wasn't meant for groups of this size. You could basically march around for months and months on end without ever coming into contact with the enemy army or getting very far. All this basically means that if you were the invading force, it made the most sense to head towards fixed points: forts, towns, cities, etc. So sieges were the most common tactic for basically all of that time period in Europe. So, to answer your question directly, battles ended when one of the groups gave up, just like it did in earlier time periods. This could be because of lack of food during a seige, number of deaths, people getting scared, etc. Lack of mobility/infrastructure would also be part of why commanders met during cease fires. If you want to negotiate at all quickly, it has to be face-to-face, and you can't exactly bring in someone of higher rank/importance if it'll take weeks or months to get there and back. |
The Difference Between the Use of the Army and the Marines | As my Dad would say, the Army guys just **A**ren't **R**eally **M**arines **Y**et. |
How can people make their vision blurry at will? | Mentally visualize a point at your current focal distance - the distance from your eyes, where you're seeing sharply. Now move that point further away and let your eyes focus on that new distance. You may want to practice moving the point forwards and back a bit until you feel comfortable doing so. Once you've got it, let the point zoom outward to infinity and have your eyes follow. |
What really happens when you "write something off on your taxes"? | Generally people are referring to deductions. You make X amount of money, which means you need to pay Y amount of taxes. But, some things aren't taxed the same way. If you have kids or a business, or one of a thousand other situations, you can often 'write off' certain expenses - meaning stuff that you shouldn't have been taxed on. The result is you either lower your tax bill or get a refund back if you've ended up paying more than you needed to. |
Why are mascots a big part of American sports but not so much in Europe? | Because Americans love entertainment along with their sports, think about the Superbowl for example and it's insane halftime shows. It's also about team spirit and the competitiveness with sports. Australians love it too, we also have mascots. |
How Do I Drive In The Snow? | Start slowing down early for lights so you don't get caught needing to use too much brake. Also avoid braking too much going down hills and instead used the lower gears to slow your car. Make sure you have good snow tires and check that you have a good amount of windshield wiper fluid. The salty mixture they use to prevent ice is painfully annoying on your windshield. Lastly, use your lights if there is a lot of snow coming down and try to follow the tail lights of the people in front of you. |
Why do the majority of people have a desire to control others? | The will to power and primate hierarchy. It's just in our genes to want to create as good an environment for ourselves as we can and take power over people that we can . Of course it's probably some kind of pathology if you've got a strong desire to control others. |
How to set up a company from A to Z | I suggest getting an accountant asap. They will help you figure out if you need to incorporate, LLC, etc. Tax-wise, they can make a big difference I had started my business as sole-proprietorship but I'm getting killed on taxes this year. Had I gone to an accountant at the beginning, I would have incorporated from the get-go and saved money on taxes. But that all depends on what your business is like so their knowledge is necessary. My accountant helped me with my tax ID number and all that too. |
Why is Dennis Hastert being indicted for deliberately structuring cash withdrawals to avoid bank reporting requirements when it is legal to withdraw less than $10,000 without reporting it? | He was withdrawing more than $10,000. He just pretended he was making a bunch of unrelated withdrawals less than $10,000 so the bank wouldn't make a report about it. That's a crime. |
Why is there no other color for pee? | Because we've evolved to use as much of what we eat/drink. The kidneys filter out what we don't and we excrete the waste, which is generally the same thing . The more waste the more deep yellow the urine is, the less waste the clearer. Similarly, feces tends to be brown because of the excess hemoglobin from dead blood cells regardless of what you eat .I have had both clear and yellow pee, as well as red. What do you mean? Would coffee actually make pee turn black? |
If light takes so long to reach Earth, isn't the viewable Universe COMPLETELY different than what we are seeing? | When we look at the night sky, we're looking at the past. The star you're looking at has probably not been there for a long time. **EDIT:** Not sure why I'm being downvoted. Stars and galaxies do move and shift location. A star could go supernova right now, but we would not be able to observe it until years later, depending on its distance.Has anyone ever tried to make a model that factors in the distance of stars and how long they last, giving an idea what the sky actually looks like right now? Is that even feasible? |
why on some streets the house numbers skip a number. | So, my street address is 301. The house next door should be 303, one would think. But it's not. It's 307. Why? Because my property takes up three lots. |
Explain it like I'm an old white guy, what is the difference between rap and hip-hop? | Most of the answers here are only getting it partly right. DJ Afrika Bambaataa was one of the originators of HipHop. At the outset, he identified four elements to Hip Hop culture: rapping, breakdancing, graffiti and djing. These days, most people don't practice all four. But the word Hip Hop still refers to those elements, with rapping and DJing being the most popularly associated with the term.Hip Hop is a culture with 4 main elements to represent them; 1. Emcees who are lyricists that rap on tracks. 2. B-Boys who are the dancers to the music 3. Graffiti which is the visual art form of Hip Hop 4. DJs who are the ones that mix and play and spread the musical part of Hip Hop. There is also the lost element which ultimately began the rise of hip hop which is 5. Knowledge The term Hip Hop comes from the roots of being Hip which means to be aware and Hop which is a movement to keep it moving and be aware of the world around youCheck out a movie called "Style Wars". All you need to know. _URL_0_"Rapping" itself is the vocal piece of the music, the same as "singing". There is no difference between rap music and hip-hop music. There is no difference other than contrived ass definitions from people that think all mainstream hip-hop is bad. The one exception I can think of would with instrumental hip-hop. It 'd be weird to tall that rap music, because there are no lyrics. "Hip-hop" is a culture/movement too. |
Up until about ten years ago, people in photos taken with flash almost always came out with red eyes, but now you never see people with red eyes in pictures - what happened? | The red-eye effect is caused by the camera flash reflecting off the back of the subject's eyes. Newer cameras and phones have special lights and sensors that prevent this. |
How is Greenland considered the largest island? | If you were to include continents in your definition of islands, Australia still wouldn't be the largest Island, because then you would also have to include 'Islands' like the Americas or Afro-Eurasia. |
why doesn't reddit just automatically have the features on RES? Everything is improved, so why not just adopt it? | This was asked before and the answer we came to was about bandwidth costs. The standard reddit page is only a small size . However with all the features of RES, there's much more content being loaded on the page and this increases the page size . When you take into account the millions of hits reddit gets, if each page is 50KB bigger, and you have millions of people refreshing the page or going to different subreddits, it all adds up in cost. By having RES as an optional extra, it means only those who want it can use it and reddit doesn't have to spend additional money on people who don't want it or who will not use it. |
What is it about cancer that actually kills you? | Cancer cells are normal cells turned into useless waste-of-space cells. They no longer work the way they should. Worse, they might just keep growing and making more dud cells. Sometimes this doesn't matter if it's small enough, or they just don't grow very much, like a skin mole, but sometimes they can grow very fast, or they cause other places in your body to grow dud cells. In the case of brain cancer, one threat is the cancer cells grow so big and so fast it acts like a wrench in the machine of how the brain normally works. Treating it is like trying to clean up an oil spill in church - you don't want to disturb how things are going, but what you can do is limited by what's allowed in. |
Why are there so many different cryptocurrencies? | They have different purposes. Bitcoin I suspect is the most reliable due to the large number of people depending on it to work correctly, so it will receive more scrutiny. But if you're attempting to use Bitcoin like cash -- an anonymous currency -- it doesn't work. However, other coins like Monero are designed to use a public ledger in an anonymous way, so it can behave like cash. For some micropayments, Bitcoin is already too expensive, even though you can go all the way down to just 1 satoshi, a fraction of a cent. That fraction is too big. Last , you may want the value of your coin not to fluctuate with the whims of the global cryptocurrency market, but with something that is more stable, by linking it to a particular use of the coin. So you get coin that is created for particular uses. |
When a house burns to the ground, why is the chimney still standing solidly behind the remnants? | It's not always but it does happen a lot, the chimney is fire proofed and a free standing smaller rectangular structure so it's one of the stronger parts of most house designs. |
How does a gun actually propel bullets? | Big 'POW' behind the bullet pushes it quickly through the tube that spins it! Not for 5 year olds.As you pull the trigger of a gun with a round in the chamber, another piece in turn causes the firing pin of the weapon to slam onto the primer , causing a mini explosion inside the chamber, as the gas pushes the lead forward it spirals through the barrel. The lead then exits the barrel and toward its target. |
How come a large portion of African Americans are such devout Christians? | After the end of slavery, churches were a form of networking, empowerment, and community-building. It was a way to grow together and grow stronger. Combine that with years of having Christian morality, rhetoric, and imagery pummeled into your head, and you've produced a devout population. It's not a one-sided issue. Slaves have said *religion had given me hope* to *the religious are the most brutal* . |
What do mile markers represent, and what are they used for? | They indicate where you are along a road -- typically measured from some starting point such as a border. They are used by maintenance crews and emergency crews to indicate exactly where something happened , if it's not near a clear landmark. |
Why do people tend to overeat food but not to over-drink water? | I find people rarely overeat healthy foods. It's the same with liquids. There are a lot of people that over-drink sodas. |
Why is the Daily Mail not generally seen as an unacceptable source for news, the same way that every other tabloid paper in the world is? | _URL_0_ The daily mail are racist scum that supported the nazi's and run blatantly anti-semitic articles in the run up to WWII. _URL_1_hurrah-for-the-blackshirts/ _URL_1_", 'I am American and I see it as a Tabloid, does the UK not?You have a double negative in your question which is confusing people. |
Why does it seem that the overwhelming majority of comedians lean left on the political spectrum? | Simple. Most of the ideas representing conservative/reactionary thought naturally lends itself to a portrait of mean-spiritedness. This may sound biased, but it's actually a huge disadvantage for those aligned to the right of the political spectrum. For example, speaking disparagingly of those on the lower rungs of the socio-economic ladder comes off as cruel and callous. Alternatively, a typically liberal comic has a much easier target at a billionaire and his/her ill-gotten gains. Another example: speaking freely about sex. For most people whose ideas of acceptable sexual behavior is informed by an immutable religious commandment–they will most likely be aligned with a culture that maintains tradition/status quo. Comedians operate off a natural shock-value of pushing the envelope on said issue. Thus, a conservative entertainer cannot speak on such an issue without the risk of alienating conservative audiences. But there are conservative comedic acts. Most members of the Blue Collar Comedy troupe appeal to conservative ideals, but potential audiences are often dismayed that their brand of humor often appeals to the lowest common denominator, typically expressing disapproval of how things are generally always changing in a manner that makes them less familiar . While some of these critiques may be valid, it paints a portrait of conservative comedy being crotchety and mean. |
How does bail/bail bondsmen work? | You'd pay the bail bondsman $5000 which you don't get back, he gets you out of jail by promising to pay the $50,000 if you don't appear in court. If you fail to appear he can hire bounty hunters to track you down and force you to appear in court in order to get his $50,000 back. If you are in a position to post $50,000 cash or you can put up the title to your house as insurance then you get 100% of that money back when you appear in court. |
Why is a single worldwide government not possible? | Well, it's not impossible, certainly not in the modern age with our current military and communications technology. The problem is that everywhere is different. There are so many different cultures living in so many different circumstances that a single government, with a single set of laws and so on, would never work for everyone. You'd basically have to more or less stamp out all the different cultures first . So unless you're up for the world's biggest genocide ever, no world government. But you *could*, technically, do it. But it'd be hard, and it probably still wouldn't work well. It's far easier to deal with local issues locally. Consider that the USA has military bases in 130 countries. A traditional empire would've annexed all 130 countries and tried to govern the whole thing. That would be incredibly unwieldy. The USA just puts bases everywhere and leaves the local governments intact , though under the watchful eyes of US soldiers. That's a lot easier for the USA, and it also means a lot less fighting. And that's why we don't have anything close to a one-world government: it'd be worse for everyone involved.If the people governed have the feeling that they are being lead by a worldwide government, then it will be possible. If the people governed have the feeling that they are being ruled by a worldwide government, then it will be nasty. Currently there are several global communities where nations participate in: The United Nations, the World Trade Organisation, the North Atlantic Treaty, the Organization of the Petroleum Exporting Countries etc. They are all based on individual countries coming together to chase a common goal. That is most likely the best we will get with regards to global governments.Have you ever been to a local municipal town meeting? There is your answer. You can't even get a few 'Neighbors' to agree. |
How do GPS apps like Google Maps know so accurately what traffic is like and where road work is happening? | Former traffic reporter here. There's a few ways they gather the data. Much of it is actually supplied by government databases. The transportation department uses a combination of CCTV cameras and sensors in the road to gather information on collisions, traffic speed, etc. They'll also have a master list of all planned roadwork for the day. For large cities, the app company may actually have people manually inputting data. Which was part of my job when I worked for a reasonably well known, but now defunct traffic app. I'd watch traffic cameras, get phone calls from motorists, listen to police scanners, and input that into our backend. A lot of apps rely on UGC to fill in gaps. Waze is best known for this. UGC isn't as accurate but it's good enough for most purposes. The app will also use your phone's GPS to monitor your speed. An algorithm then makes an average speed for a particular stretch of road, then compare it to the speed limit.The GPS switch on your phone is on. Every so often it sends a little message back to google saying "hey, I'm here" with the co-ordinates. a short time later it does the same thing. Back at base, google can look at the two messages and can figure out how far you moved. Now imagine everyone else's phone on the same road does the same. This creates a trend in data, for example it might show that there are 50 cars all doing 10mph. That is abnormal and therefore gets shown as a red section on the map. So there is a bit more to it but thats the basis. |
how a black man and a white man with all the same size body parts have distinct voices where you can tell their nationalities apart before even seeing them | I know what you mean it's not about the accent or pronunciation. It's more about the pitch. I've always wondered this.I worked for a black dude that sounded like a white cowboy from central Texas. I talked to him over the phone first, so when I walked in and a tall white cowboy looking dude said "Howdy." I asked if he was my boss. A few moments later I found out why he gave such a chuckle.There are 3 different explanations for what you ask 1)Different races have different morphology in their body, that includes their lips, the inside of their mouth, nostrils, etc.; All of this will influence the sound of a person's voice, but this will be very hard to hear and it will change from person to person 2) there are some psychological effects that can make you believe that you can differentiate between races by voice alone it may be that you're being Influenced by stereotypes from the past or it may be something similar to the Buba/Kiki effect, that makes you relate, in your head, the low-pitched or high-pitched sounds, with the race that you think that makes more sense, similar to if you see two people, one skinny and another fat, you would think that the fat one would have a lower pitched voice than the skinny one There is also the chance that it's both or some other psychological effect 3) people, when growing up, tend to imitate different tendencies, which will shape the way they speak.This is dialect and accent, which are learned, plus simply the depth of your voice, which varies a lot between people. Rick Astley, for instance, is quite white, but people hearing him on the radio thought he was Black, which hurt his ratings. |
why the founding fathers of
America believed in freedom and liberty
for all men yet were slave owners? | I suggest you read [A People's History of the United States by Howard Zinn,] if you'd like to know more. |
Why is it detrimental to laptop batteries if left plugged in for extended periods of time and do mobile phones fall victim to this dame problem over time? | It's a myth. Old battery types, such as NiCd had such problems. Modern batteries are quite robust, and handled by intelligent charging circuitry. You can pretty much abuse them whatever way you want. Run them dry , keep them topped up at all time, cycle them, it doesn't matter. There might be a measureable difference, but it won't be a noticeable difference. So, with modern batteries, it doesn't matter. Use them as you like, and stop perpetuating a myth based on something that doesn't apply anymore. Chances are that the device is olde before the batteries are old anyway. |
Why did the allies expect the Maginot Line to work? | You're forgetting that Belgium was not defenseless. There were [several major fortresses around Liege] and around [Namur]. The idea was that these fortresses would hold the Germans back until French forces arrived, holding Germany back. The plan ran into several issues. 1) Belgium claimed neutrality, preventing French forces from backing up the Belgian lines prior to invasion 2) Belgium somehow didn't believe the impending invasion, leading in forts being undermanned. 3) The German forces moved far faster than expected 4) The forts were build to fight ww1, not ww2. Air defenses were severely inadequate. As an example, the [Fortress of Eben-Emael] was the largest fortress in the world, and supposedly impenetrable. The Germans landed ~80 men in Gliders, and completely disabled it in a matter of minutes. Other fortresses on the line were bombed or disabled in other ways. |
Why can I eat large quantities of fast food but only small quantities of healthier food? | Complex carbohydrates vs Simple carbohydrates. The Food Doctor books are really good at tackling this; essentially about how the increase in fiber will make your food take slower to digest, and how the milder effect on your blood sugar increases appetite control. So whole wheat, starchy vegetables, legumes etc are counted as complex and are often touted as the healthier alternative. I don't know if it answers your question in it's entirety, but it can explain why you feel fuller after brown pasta than with white. Regarding the McDonalds: looking at the calorie tables they've provided, you only get 2-3 grams of fiber per burger. It is recommended that women have 25g a day, and that men have 38g. This could explain why you don't get the same full feeling when consuming the same amount of calories from a different source. So if you had 4 Big Macs, you would consume 2200 calories but only 12 grams of fiber which is less than half for a woman, and less than a third for a man. Hope this helps :') |
Why do I need to dial nine to call people outside of my company building? | '9' is just the standard number to tell your Business Telephone System that the number you are about to dial is not an internal number but an external one. It just tells your phone system to send the call outside of the company. Some modern systems are smart enough to know that a number is external vs internal, and don't require it anymore so the requirement may be going away as businesses upgrade their telephone systems.Most phone systems at work think that when you pick up the phone, you're going to be calling someone else inside the building, usually by just dialing their extension . By dialing 9 first, you're saying "hey, the call I'm about to make needs to be routed outside the building". |
Why is the USA made up of different huge states (with different laws) instead of 50 independent countries? | You've probably been told this already, but if you read The Federalist Papers , not even the whole thing just the first few articles, there are very, very solid arguments on why having The Articles of Confederation is terrible. |
Is there anything that tastes salty but isn't salt? | All alkali metal ions have similar salty taste profiles, because it's caused by those positive ions entering specialised taste receptor cells in your taste buds - of which there can be up to about 100 on each - so there's a good bit of resolution when it comes to that. The further you go down the alkali metal group the less salty it will taste, because the ions get hella big. In the case of hydrogen ions however, that infers a tart or sour taste. Other basic flavours come from more complex proteins in the receptor, but any combination of which is responsible for a given taste.Magnesium. Specifically in magnesium citrate. It is extremely salt-like taste and can also cause massive diarrhea. |
Why do we have 2 machines for washing and drying clothes? Why isn't it 1 machine like for dishes? | That have ones that are combo washer/dryer, but they are completely terrible. You can't readily accomplish this with a good forced-air dryer, so they have to use the substandard condenser drying method. Condenser-based drying uses more energy, is rougher on the clothes , takes longer, and produces inferior results. Basically, you will only seem them where there is no space for a proper washer/dryer or even a stackable.I used to have an apt that came with a combo washer/dryer. It was a piece of absolute garbage. Decent at washing, but the best I ever got was warm dampness after running a "drying" cycle. |
Why do countries that generate a lot of energy through nuclear power plants, such as Switzerland, want to remove nuclear power if they have seen no negative consequences from it? | TL;DR: Fear, plus solar seems to get more and more efficient. If you are interested in various pro/contra i'd suggest you take a look at this playlist. Sintetic, animated and easy to follow ELI5 level.[Kurzgesagt] |
I've often heard people say that America is lawsuit-happy, but how exactly is that different from Europe? Do other countries not have so many lawyers? | Such silly lawsuits are often seen as childish and they are thrown out of court. Often such trolls will get fines from the court for wasting the court's time too. |
Why most of security footage isn't high quality? | You have to store a lot of it. You need to decide what capacity you want available. A few hours? A few days? Weeks? It gets expensive to store all that, and it gets ridiculously expensive if you also want it to be high quality. Remember, the vast majority of the time you're recording nothing. That's a lot of hard drive space and money wasted for no good reason. Of course, there are clever ways around that. For instance, you can use an image processing technique to detect motion or change in your image, and only record when motion is taking place. But this is only useful if you're recording a mostly unused entryway or corridor. Using this to record in a supermarket would be pointless - it would still be recording all the time. |
Why staying in the same place is universally accepted as giving you better chances to get found when lost on a hike? | Staying put also allows you to conserve energy, create some form of shelter and maybe do signalling devices, a fire.These help you survive - you're protected from elements, you are warm and you are conserving energy. It is much easier to find a stationary target than a moving one |
How did Hitler advance in the ranks of the national socialist party? | Basically, he was a very effective speaker, and won quite a lot of new members for the growing Nazi Party. He also had managed to win over quite a few wealthy donors. In 1921, we dramatically left the party in a huff over a proposed merger with the German Socialist Party. The Nazi Party, though, really needed somebody as charismatic and effective as Hitler, and wanted him back. In return, Hitler demanded some changes to the party organisation. The party accepted, and promoted Hitler to party leader with all the changes he'd demanded, making it easy for him to centralize power and steer the party in the direction he wanted it to go.He was reasonably bright, articulate, verbose, and charismatic. He used his skills to hit particular points of contention to raise his own popularity and further the agendaNot to mention germany went nearly bankrupt so anyone with a plan to get them back on track was seen as a godsend. |
Why are old houses built better than new construction? | I do see homes with hardwood floors. Ours does, and it's not a high end home, but hardwood is popular in Boston suburbs. On the flip side, unless it's been upgraded or the builder was at the leading edge, that 1930s home probably has knob and tube wiring, or at most two wire wiring, with maybe one or two outlets per room, and a fuse box instead of circuit breakers, and maybe just 60 amp service. GFCI outlets would be an upgrade. The bathtub might not have had a shower originally. One thing people haven't mentioned is that labor was proportionately cheaper back then. Homes use sheetrock now because plaster skimcoats require more skill and labor. A good hardwood floor requires some expertise for the finish coat; laminate or prefinished hardwood is cheaper. |
Why do people buy insurance, as opposed to saving the money you would've put in, and using that in times of need? | You probably can't save that much money yourself, and there's always a chance you'll need it relatively soon. You can't plan ahead and save up for something like meningitis or a stroke or cancer, they just come at you out of nowhere and can happen at a very wide range of ages and can cumulatively cost more than you'd make in a decade to treat. So we as a society invented insurance to pool the risk, some end up needing it and some do not, but you can't know which group you're in until you're just about dead.You can withdraw from the pool of risk before you have contributed more than you will have taken out. Consider the scenario where you get in a car accident a month after your insurance starts: you would have paid in maybe $50 into insurance but would get thousands of dollars of benefits from that accidentOne probably should do just that for small items such as a new television or home appliance, but large items such as a house are simply too expensive fir the average person to save for. |
why is there no widespread kitchen utility that can freeze something in the time that a microwave can heat something? | They have blast freezers for food processing plants and speed chillers in some fancy restaurants. There is even a chain of ice cream shops that uses liquid nitrogen to instantly freeze custom made ice cream. As for home use, they are very expensive to own and operate, and most home buyers won't want one. |
How does getting the wind knocked out of you work? | Your diaphragm is paralyzed from the blow you get to your stomach, therefore, you can't use it to breathe, and you get a short of breath feeling. |
is the US senate undemocratic? | It's a Democratic Republic because you democratically choose Representatives. The Senate is the way it is so states with high populations can't simply take all the money. It's undemocratic because people and money are involved. Happy birthday I hope 6 treats you better than 5 |
Why don't film production companies hire movie critics to help them make a good movie? | I know what a good soup tastes like, but that doesn't mean I know how to make a good soup. I can taste a lot of completed soups and tell you which ones I liked and why, but asking me to taste soups as they're being made and predicting whether they'll be good would be difficult. |
If the US unemployment rate is less than 10%, why do i keep hearing that every job posting gets hundreds of applicants? | Firstly, the unemployment rate measures the number of people who are still in the job market. If you stopped collecting unemployment, and stopped going to the unemployment office to have them help you look for work, you're not being counted in that number. Second, If there are hundreds of people in the job market, each job opening can get hundreds of applicants . Also, people who are working can also apply for a job if they think it's better than what they currently have. |
How is premium petrol different from regular, and how is it made differently? | Since no one has answered yet, I'll take a stab at your question, but I'm in no way an expert, this is just my understanding on the subject. Premium gas is not really made differently, it just has a higher amount of octane compared to regular gas. Octane makes fuel harder to burn, so in higher compression motors, it will help prevent detonation . Detonation is why some cars require premium gas, not because they are fuel connoisseurs and require only the finest fuel. Still, in cars that require premium, you can get away with just regular as long as you're not taking the motor to high RPMs. With that being said, there are also additives that are usually added to premium fuels which can range from useful to useless. Which additives are added usually depends on the company making the fuel. The stuff they add is usually the same stuff you can find in a car shop that you add to your gas tank to clean injectors, or unfreeze gas lines, etc. |
What happens if a national crisis occurs while the President of the United States has been drinking at a social event or privately? | No one let's the President drink to excess while he is the President. There are teams of people surrounding him to ensure that he is always prepared for anything. Some of our Presidents were drunks, but we learned that lesson and now the President is more of a Prisoner, and monitored very closely. If the President wanted to imbibe more than appropriate, some Secret Service would appear and usher him off to his room before that happened. However, on the off chance that it did happen, the Vice President could declare the President unfit for duty. It really hasn't happened. There are teams of people in place making sure it doesn't. |
If Hitler was a socialist, a leftist political ideology, why are Neo Nazi parties like the Golden Dawn considered the 'far right'? | Nazism and fascism on the whole doesn't neatly fit on the left/right political spectrum that people like to use to simplify political conversations. That being said, Hitler was not a Leftist. |
Why do Li-Ion batteries lose their capacity when you overcharge them? | Most of them are susceptible to heat, which is what will happen when you overcharge any battery. Heat is usually the primary reason why batteries have shorter lives. This applies to regular batteries as well, which is why they suggest you store them in a cool, dry place. Rechargeable batteries like to be charged also and kept charged. If they aren't charged, some of them can eventually develop issues also. But overheating a battery will affect its life for sure, which is why you should use an intelligent charger, or some kind of timer that shuts off the charging once it is complete or shortly thereafter. Or, disconnect it yourself. Belkin and other manufacturers make timers you can plug things into. The one I have has settings for .5, 3, and 6 hours. I use the 3 hour setting for my laptop and my phone. Plug it in, hook it to the device, click the top and it shuts off after 3 hours so the battery doesn't overheat. It also goes without saying if you're charging your battery, its probably not best to do it in your 100 degree car. The heat of the car plus the heat from the charge is a double whammy. |
How can people believe with so much confidence in something that is obviously false. | At a fundamental level it has a lot to do with people's tendency to conflate their ideas with their identity. Thus, a person might perceive a critique of their ideas as an attack on them as a person, and they can no more simply submit to such an attack than they could if someone were to physically attack them. In extreme cases, plain and clear factual information that directly, immediately, and soundly contradicts one's beliefs is less important than maintaining one's identity . This is why things like the Socratic Method are more effective means of persuasion than simply throwing facts at the person you're arguing with; the idea that they're mistaken has to be *their* idea, not yours, or it will be rejected without even being considered. Much of the goal of critical thinking classes is to get people to overcome this habit and to get comfortable with the idea that they *will* be wrong often, and that recognizing when they're wrong creates a chance to become less wrong. But whether critical thinking is taught widely is largely a matter of culture. Sad to say, it is not highly valued in the US, among other places. |
Why did we (USA) bomb Iraq today? What does this mean for our country? | We have always bombed iraq. [Our fathers did it], our [fathers' fathers did it], and our children will continue to do it for generations to come. Its a tradition!", 'They are going to kill all these people! Lets kill all of them! |
How do planes flying in tight formation (i.e. the Blue Angels) not get screwed up by the other planes' jet wash or other machine-made turbulence? | The effect of the other planes is at its strongest when landing or taking off I don't think it causes as much of an issue when your actually in the air as there's so much room for the air to move in |
What is the .1% of bacteria that Lysol doesn't kill? | Nothing kills 100% of bacteria. In fact, most antibacterial soaps kill 99.9% of bacteria, because for a product to be classified as a decontaminant it has to reduce bacterial levels by a factor of 1000. So it's just a marketing tool to imply that their product is good, when in fact all similar products do exactly the same. Disinfectants like iodine will reduce bacteria by a factor of 10 000 within 5 minutes. It's also important to remember that when dealing with bacteria you have to think in logarithmic terms, since they multiply exponentially. When you think in log terms, Lysol is actually pretty weak; you have 10^8 bacteria on your hands on average, and Lysol will bring it down to 10^5, so still 100K bacteria sitting on your hands. Iodine will bring it down to 10^3, so 1000 left. |
Why do humans have dominant hands? Do other species have dominant sides as well? | I'm in no way an expert. All I can do is point out that there are crustacean species that have larger claws on one side. Basically, if it helps you survive to have one appendage that is better at details, and one that is better at broad strokes or strength, those traits continue. It's probably a leftover, and there is no evolutionary pressure to prefer one side or the other. Right handedness is just more likely, due to genes and it already being more common. |
Why does Hollywood continually cast people in who are 20+ to play teenagers? | Because it feeds into a fantasy of what that market wants. It's the same way they use older children to advertise toys. A child is more receptive to an older child playing with them than a child their own age or younger. Most teens feel as if they're adults and are dealing with adult subject matter, such as sex or work, so they want that reflected in the characters portraying them. Adults who look young. |
Why does running long distance kill my appetite? | Some animals have the strongest bite, or the sharpest eyes. These animals stand out for their exceptional ability. Aside from intelligence, humans are the best in the animal kingdom at one other thing: long-distance running. Humans are the best long-distance runners in the world—we have the best stamina for running of any animal. Humans can, with the exception of sprinting, outrun both prey and predators 100% of the time. If you chase a deer across open country barefooted, eventually it will collapse from exhaustion and you will be able to kill it with your bare hands. We've evolved this trait over many thousands of years and it has served us well. It has shaped our bodies. It has shaped our culture: imagine human warfare if marching were impossible beyond a period of 15-20 minutes. Consequently, your body has many adaptations that make it better at running. Digesting food? That takes energy. If we're running long-distance, we must be chasing prey or escaping a predator right? Processing food doesn't matter right now. Of course your appetite won't be suppressed by swimming, or lifting weights, or whatever—those things aren't running. Running is a special human activity. To paraphrase a certain American politician, your body has ways of shutting it down because it 'knows' what's going on. TL;DR: humans are extremely specialised runners, moreso than any other animal, and, consequently, shut down unnecessary bodily functions during prolonged running to conserve energy. |
Why is it that dry-firing (pulling the trigger without any ammunition) bad for airsoft/real guns? | The energy of the cocked gun is supposed to be transfered to the objective . When there is no pellet or cartridge, that energy goes to smacking the hammer or slide into the frame of the weapon that normally holds the pellet or cartridge. This mis-directed force can deform the parts, especially over repeated occurrence. And maybe not just at the relatively sturdy points of contact. Guns are actually very close tolerance, precision machines designed to deal with specific forces in specific ways. Dry-fire impact forces are _not_ the forces they are designed to regularly experience. EDIT: Modern materials and designs largely make this an urban legend for modern real guns. I'll take /u/starchbased at his word that the airsoft was going to break no matter what; I didn't draw any distinction there for lack of info but his analysis sounds spot on. The rim-fire point also sounds good. I'd amplify that a modern gun made with modern metals probably needs to be dry fired _hundreds_ of times to be bad, if even then. But a side arm from WWII or before likely had real issues even with a sliding pin. The age of idiot-proof firearm construction is probably younger than I am. |
Why do "healthy" foods cost so much more than "unhealthy" ones? | Fast food is definitely a different story. Those guys sell how many burgers in a day? Compared to the farmer and producers who put lots of time and money into creating healthy organic foods. Healthy food, you pay for the effort that gets put into making it then distributing it to places that don't produce it themselves. In some cases healthy food is more expensive compared to Mcdonalds. BUT. I can go to the store and spend $40 and have veg fruit and healthy protien for a week. Or spend $40 & get a bunch of pop, pizza pops, pizzas, canned ravioli, chips that'll roughly last the same amount of time. I'm just going based off of my own opinions and life experiences! Just how I think about it! Who knows if its bullshit or not. |
Why the US has tipping instead of servers being paid more | one word: capitalism. the best servers get the best tips, most business, last longest, and work harder for those tips. they have an incentive to excel. america is money and capitalism driven; without a incentive to work harder and do better, most people won't. |
Why are the red lines on the British flag not centered? | Wow, I've never noticed that before. It looks off like it's a mistake but having read some other comments I know it's like that on purpose ", 'The british flag is made up of three flags layered on top of each other, the english one, the northern irish one and the scottish one. Since the irish flag has the red X and the scottish one the white X, some duder thought back in the day "Why not keep both colors in the X?" and that's why the lines are offset. |
why is it that when you're very sick and throwing up, laying down on the floor feels so comfortable | This is anecdotal, but I had nervous nausea for some years so I've puked sooooo many times and spent many hours on the bathroom floor. I definitely agree with what everyone says, but I also want to make the point that a lot of it is probably psychological. The bathroom floor is close to the toilet, and even if you puke directly on the floor, it's a lot easier to clean up than bedsheets, pillows etc. It just means less hassle. Also, right after puking, you get really relaxed so the easiest thing is to just lay down right where you were. Sometimes I've puked in a bucket next to the bed, and leaning right back into the bed felt even better than laying on the bathroom floor. I don't think the floor in itself is more comfortable, I think it's just because it's close and hassle-free. |
How are the people on the Discovery Channel show "Moonshiners" not in prison? | Explain like I'm five has just turned into lazy people getting their questions answered. It used to be complex topics that couldn't be easily understood with just a quick google answered by knowledgeable redditors. |
How can the average person prove the earth is round? | I'm not suggesting you actually do this, but this is how you *could* do it: Put a stick in the ground, face north, and measure the angle of the sticks shadow from north, at a particular time. The next day, travel a few miles south, and repeat the same procedure, at the same time. There will be a difference in the angles, and after a bit of thinking you realise that that could only happen on a curved surface, not a flat one. That's how they did it about 2500 years ago. |
Why do British people sound American when they sing? | Lots of exceptions mentioned in this thread, but I get what you're saying when it comes to rock/pop music. It's because British bands were influenced by the American rock'n'roll singers of the 50s. The Beatles - the most influential band of AT LEAST the 60s - did American accents when singing because they were imitating their heroes. Same with the Stones. It just sounds cooler to a lot of rock singers. edit: grammar |
How is the world able to function if most people don't know how the things they use everyday even work? | Why would they need to know how it works? They just need to know how to use it. Ancient humans didn't know how fire worked, but that didn't stop them from figuring out how to use it to help them spread out over the entire world. Very few people back in the day new how gunpowder worked, but that didn't stop them from using guns in wars. All you need is a handful of specialized people to know how something works and how to make it. Everyone else just needs to know how to use it. History is full of examples of technology like this. It'd be impossible for 99% of the people to learn how every single device they use works. |
Why do home air conditioners have to suck air from outside? Why can't they suck air from inside and just make that air cold? | Nothing can 'make' cold, it can only put the heat elsewhere. Putting it outside is the most practical way to do it for home-use. Just thermodynamics; your fridge is also spewing out warm air to keep it cold inside. |
Why do immigrant activists think illegal immigrants should be allowed to stay in the US even though they are breaking the law? | Even though the U.S. allows more LEGAL immigrants than all other nations combined, people still want more. We cannot take all people from all over the world, there has to be a limit. The limit is easily high enough already. Take Mexico for example. They have some of the harshest laws against illegal immigration which is usually targeted at the Guatemalans that illegally enter Mexico to work. The Mexican government understands that it is bad for a country to allow an unlimited number of very poor people to sneak into its country. But, if you say that in the U.S., people will call you racist. Read some of Ceasar Chavez's writings. He was very against illegal immigration because he said it drives down wages for the poor that are legally here. His message has been corrupted by today's crusaders. |
Why can't we divide by 0? | Think about what happens when you divide by less than 1. 1/=2, 1/=4, 1/=8 And so on. As the number you divide by gets closer to 0, your answer gets larger and larger. For every number you can name, no matter how large, there is a fraction that you can divide 1 by to get to that number. That fraction will always be the inverse of that number. Now tell me, what is 0 the inverse of? It's uh Undefined.division by zero is "undefined" exactly because there is no definition of division by zero that EVER makes any sense because multiplication of any fixed value x by zero is ALWAYS zero, meaning there is no way to ever "undo" it and recover the original fixed value x. There are many mathematical structures where division is undefined for some values, but it is ALWAYS THE CASE that division by zero is undefinedWell, when you're talking about dividing, you could say, "x pieces of y" Lets say X= 4 and Y= 0 That means that you're saying "4 pieces of 0" And because 0 doesn't physically exist as anything, dividing by zero doesn't workIf you split 10 apples between 5 people, everyone has 2 apples. If you split 12 oranges between 3 people, everyone has 4 oranges. If you split 2 pears between 0 people, how many pears does everyone have?How do you cut something in to no pieces? |
With the presence of Airplane Mode, why do air stewards still insist that we turn off our mobile phones? | Electronic devices are to be turned off during landing and take-off. It has little to do with interference, for instance you're not allowed earphones on with a simple mp3 player either. It's because landing and take-off are *the* most dangerous parts of the journey, for safety reasons they want you to be able to follow any instructions in the event of an emergency. That would be severely hindered if everyone was wearing earphones, watching movies, on the phone, etc.I thought I would clarify some conflicting information here. It is my understanding that the FAA has recently allowed cell phones to be on throughout the flight as long as they are in airplane mode. HOWEVER, it is up to each individual airline to decide how and when they would like to implement this. Quite a few airlines have jumped on board with this right away, but some airlines like Frontier choose to keep the old rules for nowI don't know what all of you are complaining about because that "everything needs to be off" rule was overridden a few months ago. Flew yesterday and the steward said "You're free to use electronic devices but they need to be on safe or airplane mode"', "They don't anymore. You are perfectly allowed to keep your phone on and use it during take off and landing. As long as it is airplane mode, you can use it from gate to gate. Source: I fly a lot for my job.I was on JetBlue a couple weeks ago. The only thing we had to turn off was laptops and that was only because they were big enough to be a danger if they go flying around the cabin.Phones are no longer required to be off. If there was the slightest chance that cell phones could actually interfere with proper operation of a plane, they wouldn't even allow phones to be carried on. |
How does it not hurt when guys run, also how do guys sleep on their stomach with no pain? | With regarding to your first question, the mass of the penis and scrotum isn't that much for it to gain much momentum when running. Also, the location they are in doesn't really rotate when running. With regarding to the second question, the penis and the scrotum are generally soft and flexible and there is enough space between the legs for them to be stored safely without interfering with the inability to roll over on your belly. |
I see meteors enter our atmosphere a lot, how do they not hit ISS or satellites? | Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space. |
why does this propeller appear differently in these two photographs, vertically vs. horizontally? | Here's a video that shows how the line-by-line capture of the image plus the rotation of the propeller gives you those weird shapes: _URL_2_ Here's another one that explains why not all cameras work that way: _URL_2_ |
Can humans eat a version of kibble, like a food that just contains everything in it? | I've often wished for a food product like this. I eat the same thing day in and day out during the week for breakfast and lunch already, so having something more convenient and, here's the kicker, still healthful, would be great. This kibble could come in a variety of flavors, you know, like dog food does. So I could get a scoop of biscuits n' gravy for breakfast, a scoop of bacon cheeseburger for lunch, and call it good. I'm just sayin, if I didn't have to futz around with cooking and preparation and could still be healthful that'd be awesome. While I'm dreaming I'd also like a pony :/", 'I know some grad students who worked in a primate research lab. Grad students are poor, gorilla food is close enough to human. Most of them just ate it for lunch while at work and ate normal food at night or something like that, but I know some people who ate nothing but gorilla chow for a week at a timeWell there is Soylent - _URL_3_ Also eggs contain pretty much everything you /need/, but as a tonne of people have already said we /need/ diversity in our diets, so we could survive, but it would have pretty bad repercussions. |
Why does music in 4/4 time sounds more natural to us? | It's cultural. Many other cultures use very different timing. Indian music is one of note, I believe. I've often heard that a lot of religious music from ~400 years ago was in waltz form as the 3 represented the holy trinity. |
How do websites know when I'm using an ad blocker ? | There are many ways. One would be using JavaScript to check if the advert you requested to be placed in a part of the site is actually there, not hidden and is containing what you expect is there. The elements on a webpage can have ID's and Classes tied to them including the box you are going to put the ad's in and using Javascript you can query these ID's to see if they exist, they are visible to the user, the size, the contents and more. If these checks fail then you then show a notice or basically put the page into a state where it becomes unusable. There are many things an Adblocker can do to get around these. For example a list could be created of the functions that the Adblocker Blocker use and override them on page load to break the adblocker. But it quickly becomes a game of cat and mouse trying to one up each other. For example Facebook now tries to hides its ad's in the HTML code by using the same ID's/Classes as the rest of the timeline. |
Why the French and English didn't constantly invade each other during their wars, despite being narrowly separated? | Don't be fooled by the short distance and the sophistication of modern shipping in to thinking it would have been an easy journey. The experience of the Spanish Armada also befell many others. Think of how long it took the Romans to conquer areas of Britain long after they'd conquered Gaul which included modern day France. 200 or so years! And Britain had been renowned for many centuries for it's mineral wealth and became one of the most important provinces when it *was* finally conquered, so it wasn't as if they weren't motivated to nab it! There was trade to and from Britain from the continent - but an army that needs to carry heavy weapons and horses etc is a lot more difficult to transport over water than trade-cargo. Julius Caesar finally managed to persuade his army to risk the journey, which was pretty much considered a suicide mission by experienced Roman sailors, but only because of his immense political power, if he'd been weak it's highly possible that the army would have rebelled rather than risked the journey. We don't have as many bad ship wrecks nowadays of course, but that's because we have the shipping forecasts, the royal national lifeboat instition, the coast guard, GPS and SAT nav, radio and sonar etc etc etc and even with all this modern know how ship wrecks do still occur To emphasise: A Roman soldier would have sooner agreed to shepherd an Elephant over the Alps than to sail with full armour, weaponry, horses etc across the channel", 'tactics and technology, it would be hard for any large group of ships at the time to show up without warning, a mass of swordsman charging the beach would be struck down by archers, a group of archers would be dead before they found a target. It wasn't until Colt "made all men equal" that you could have a thing like the Marine Corps I realize that this is oversimplified, but it is ELI5, be kind. |
Why do multivitamins have 5% daily value for some vitamins/nutrients and 1500% for others? | Other answers are good but there are other interesting factors in play for specific nutrients. Potassium recommended daily intake in the United States is 4700mg. Besides the fact that few people could swallow a pill that large, and that you're better off taking in potassium throughout the day rather than all at once, there's another factor that not many people know about. The FDA only allows supplements to contain a maximum of 99mg of potassium per pill. This is because a large, solid block of potassium slowly dissolving in your stomach could cause tissue damage. The larger a pill is, the more time it takes to dissolve, and a large potassium pill could potentially eat a hole in your stomach. Besides limiting pills to 99mg of potassium, supplement makers are also forbidden from recommending that you take more than one pill at a time, since pills taken together could settle in the same spot in your stomach and cause damage. So to get all your potassium from pills, not only would you need 47 of them, you'd need to space them out throughout the day. Larger extended-release potassium pills are available by prescription. |
Are mentally ill people aware of their current mental state? | I have a bipolar and if I'm very manic or depressive I'm not aware of my thoughts or actions. I'm thoroughly convinced that they are normal. It isn't until after when I stabilize that I realize how wrong I am. But whenever I get back in that state I don't realize I'm acting that way. I just think I'm having a good or bad day without realizing the fact that it's extremely exaggerated compared to how normal people feel. |
Why was acting quality in movies and TV shows a lot worse a few decades ago? | If you're referring to the 80's, it's because everyone was high on cocaine. And they couldn't have given a shit about acting or writing in movies. |
How come game creators can't make the game with the same graphics as they show in the trailers? | It's the difference between a train set, and a remote control car. The train follows a fixed route. It only ever follows that route, and you only need to build that route. The RC car goes everywhere. It needs to be able to react to whatever the user is doing, and you need to build the whole room in the game. It takes a lot more work. |
Why do trucks that carry liquids have cylindrical tankers? Wouldn't you be able to carry more volume in a rectangular container? | Like others have said, it's all about pressure. A liquid pushes out perpendicular to the wall of the container, to simplify it. So when you have the corner of a rectangle there is equal pressure pushing down, against side 1 and against side 2 creating enormous pressure on that seam. On a cylinder it is equally distributed because perpendicular to the side is an arc, like how an arch Is so strong. Then you have a welded seam on a rectangle which can be a weak points whereas a cylinder is mostly just 1 piece rolled into a tank. There is probably a better way of phrasing all this. |
What is a "credit score" and why is it so important in US? | In Australia credit reports show defaults and applications for credit only. I moved house once, the gas bill of $120 wasn't forwarded to our new address in the 30 days we had mail forwarding set up. 4 years later we applied for a loan to buy another house the bank required an explanation as to why we had skipped in the gas bill we knew nothing about. Defaults stay on your record for 7 years. |
How did game developers for old games like Super Mario put graphics, music, logic, etc using just tens of kilobytes? | Image-wise, They used a sprite sheet with extreme efficiency. Musically, the sounds were handled similarly with a handful of tones used at different speeds to create strings of tones that were then used at different speeds to create music and sound effects. The media content that comprised the entirety of the game could easily have been 13 tones x how ever many scales and a single, large image with an incredibly small amount of colors, corners and edges likely reused as available. The rest was text, also used efficiently and cleanly. Coukd have even been more efficient than that. |
house party noise VS. construction noise at night? | I've never seen road construction near a residential area at 3 AM. I would like to see a source saying that the premise you are setting up actually occurs.There is a fine line between what govt does in the name of development and enforcement, but after a while both fuck you up. |
Why can't I breathe in when a gust of fast wind hits my face? For example, while in an open windowed and fast car or bus | I'm just glad to know I'm not the only person that happens to. It has been the thing that scares me about skydiving more than the height really. |
How come since 1986, we haven't been able to perfect the concorde, or at least create something similar? | Because there really isn't a lot of value of a 4 hour flight from NY to London over an 8 hour one. Add in airport hassle and customs, and you are really looking at 6 hours vs. 10. With the time change, you are pretty much wasting a day either way. And since it took about as much fuel as a 747, with a quarter of the passengers, they had to charge 4 times as much to get there 4 hours sooner. Finally, since supersonic flight creates sonic booms, those planes could only be operated over the ocean, making them inflexible to incorporate into a fleet. |
Why can I not use my own wifi router in a hotel room to provide internet to all my personal devices? | I've done it before many times. If you logged in first with a laptop you may have to spoof your Mac address on the router. Many routers have a button to do that in the wan config. |
Why aren't pet tarantulas venomous glands/claws removed before selling them to people, like some zoos do with snakes? | Tarantulas are chill. They don't bite people. I had one for durned near a decade when I was young. You can't defang or devenom them - they need that to eat. |
How do producers prevent child actors in horror movies from getting extremely scared? | Film sets look like film sets not like horror movies. There are tons of distractions booms, cameras, lights etc. Even when little kids are screaming it's because they're being asked to. Disclaimer: disregard my last in the case of The Exorcist, in which case I think she got really fucked up. Also don't include CURSED movies like Poltergeist.You have to keep in mind what the set looks like. There are usually dozens of people just barely out of camera. A lot of the time, the background is radically different just out of the camera's view. You could Google Image Search "behind the scenes" to see what this looks like, but here's one famous example from The Shining, because dealing with the child was well known: _URL_0_', "[it's the making of a 'scary' music video, and not a movie; but it might give a little insight.] |
I've heard that recent neuroscience has debunked the "left brain-right brain" idea. What do we know about the two halves of the brain? | We don't know a damned thing about the brain. We know certain chemicals act on certain neurotransmitters, how bits bind with other bits, but anything further than that is purely speculation. We don't *know* any more about the brain than the guys who measured skulls back in the victorian times to gauge criminality and other naughty things people might have gotten up to. It's a mystery yet to be truly explored because almost any testing relies on subjective experience and not objective fact. We can do double blind experiments and the like, where the subject is told they may or may not go through the experiment on that particular date, but the results always come down to personal experience. |
How is it that Red Bull costs $3 per can when it is for all practical purposes a soda? | Companies often charge what the market is willing to pay for their product. A burger and fries at ~~Steak 'n Shake~~ Jack in the Box is twice as expensive as a burger and fries at McDonald's, but people are willing to pay more for ~~Steak 'n Shake~~ Jack in the Box. Same goes for Red Bull -- they have huge brand recognition, they can charge how ever much people are willing to pay. And to be fair, even though Red Bull is usually priced at a huge premium, I often see it in gas stations 2 for $2.50 or other such promotions._URL_0_ Red Bull has things like Taurine and vitamins that increase the cost compared to soda. Also, they design and market Red Bull as something distinct from soda. In America, people drink soda like water. [In 2000 Americans were drinking 1 gallon a week!] Red Bull is more trying to compete with the coffee market. Some people like a frappuchino at Starbucks and others will take a Monster or Redbull. People are willing to pay because the drink is marketed as a 1 or less per day kind of "supplement". Even soda is way over priced. Why are you OK paying 1.79 for a a nickel of syrup in a paper cup? its because marketing has made most people unable to go to a restaurant and have a waterThe creator of redbull came out to say "how would people know it was a premium product if it didn't have a premium price?" As well as "what should it matter to you what it tastes like" Reference: [_URL_2_]', "I find it interesting how much the market changed in 25 years. In the late 80's Pepsi made a Pepsi AM with extra caffeine and it flopped. |
How can a movie theater charge you extra for buying tickets online when it actually saves them money if more people do it | It doesn't save them money right away, and they aren't set up to do it, so the hired a middleman and give them a cut. |
Why is it ok for girls to experiment with other girls but it's frowned upon when guys do the same? Why is there always a double standard? | When it comes to news on gay marriage or popular photos and stories on gay marriage, what type of couple do you see the most? I'd venture to guess you've seen more white, male marriage photos. Is that a double standard? |
How do LEDs get so hot despite putting out so much light and using relatively little power? | Most of the energy is released as light, but still not all of it. If you compare an LED to an incandescent bulb they will both get hot, but the LED gets hot only in one small spot, while the incandescent bulb gets hot all the way around. Here's a picture:_URL_0_ |
how would this (cost effective 3D printed houses) affect the economy and housing prices in America's future when America starts doing it? | its not the house itself as it is the property the house is located on. 10000 square feet in lincoln nebraska is much cheaper than 10000 square feet in manhattan. cheaper conztruction wouldn't change this much. there have already been tons of improvements over the last century to make construction quicker and cheaper, such as drywall replacing plaster, prefabricated insulated roof panels, and even prefab foundations. 3d printing is another step in this direction. all of these have made bigger, more spacious housing cheaper and more common. |
