ISIS seems to be growing every passing day, but it seems like no nation is obviously taking them seriously, why is that? | I believe that outside of the direct area and terrorist fear mongering, ISIS doesn't have the capabilities for any direct assault on a foreign country.

As a German with not much knowledge about the US, please explain why Florida is so often made fun of/spoken badly about | Florida has a high percentage of the population that has moved there from somewhere else, and a small number of the people who move there are quirky if not crazy.

Are sweatshop workers better off if their factories close down? | In University I saw a documentary on sweatshops. They interviewed some of the adult workers and they basically confirmed it. If they don't work 16 hours for 10 cents a day or whatever it is, they'd have no income at all. That's what makes them evil , they operate in regions that have everything to lose if they tried to... |
Why do all SUVs have a rear windshield wiper while almost every sedan doesn't? | It has nothing to do with water being blown off of the rear window of sedans/coupes, and everything to do with dirty water from the road being blown *onto* the rear window of SUVs and minivans. Any vertical or near-vertical surface on the back end of a vehicle is going to create an area of low pressure and low turbulen... |

How is it someone can do 100 squats but can't run but a few miles? | Strong muscles that you get from squatting, still get tired, and require a lot of oxygen, but you are not really training your breath while squatting, it that's stopping you, you just pause a while and regain your breath.

Why do we make fun of France so much? | Not going to develop about the reasons behind the stupid jokes or their major inaccurateness, but I read many times the reason they're so prevalent is that there was never a major wage of immigration from France to the US and as such there is no large French community, so Francophobia doesn't actually offend anyone in ... |
why we can secure banking/investment accts online but we can't secure voting | Millions of dollars **ARE** lost daily due to internet banking.

if we Americans strive to separate church and state, why are so many polling locations in churches? | Because churches are on every corner, they are generally under-utilized on polling days, etc basically, they're convenient and free I'm a strong advocate of separation of church and state, and this doesn't bother me at all", 'Churches don't have to pay taxes, so the least they can do to "pay the government back" for th... |
Why do Black Lives Matter protesters only show up for police-involved shootings? Why are black-on-black shootings ignored? | Black on black crime is being addressed by many communities.

How do companies like EB games and Gamestop make money when the game/console creators sell the game online for the same price? | MSRP. It's a suggested retail price which gives a basic profit margin.

How are "generations" measured? Where is the cut off? | Generation X", and most recently "millennials".

Why big companies like Samsung don't create their own Operating Systems so they could compete with Mac OS X and Windows? | APPS. they'd be so far behind the apps curve that the only possible way to compete at this point would be to go the non profit open source operating system that can grow over time.Because getting started with a new operating system is *extremely* difficult. Actually making the operating system is the easy part. The har... |
Is Sharia Law a legitimate threat in the US? | Sharia Law would be insanely hard to implement into a western country.

Furthermore, there has been little to no... |
Does religious tithing create any legal obligation for the church to the contributor? | No. Tithing is a gift, and therefore it does not impose any obligations on the recipient.

What is the simplest way you can explain left vs right when it comes to politics? | The left is riding on the lie that they are still the party of JFK and that the Republicans are standing in the way of a better life for everyone, when the truth is totalitarianism has been tried to death and it doesn't work. The right is riding on the lie that they don't want what the modern left wants, but they do, t... |
Why are people so politically charged? | Because its easy to counter one to one than to debate on exigency of any action or omission by any side of political spectrum I guess we have limited our arguments to 'with us or against us' rather than on the roads we travel .

why have some famous people of Jewish ancestry anglicized their last names ( john Stewart, bob Dylan, Natalie portman, etc.)? | Because--for a minority that secretly controls the world financial system and runs Hollywood--they seem to get discriminated against an awful lot.

why is pointing at something considered rude? | I don't know the exact correlation, but pointing at someone is usually considered an accusatory action.I 've personally never been taught that it's rude to point at an object or animal unless there's some risk of causing some type of social embarrassment. Some animals recognize the pointing gesture and some don't . So ... |
Why do some companies copyright strike Youtubers for putting their logo/product/song in their videos? | Because that's what copyright is - it means it's illegal to use their material without their permission.

Why do retailers purposely damage/break their unsold items before throw it to the garbage? Why don't they donate it instead? | Because it gets people used to getting free things from a business. I worked at a McDonald's once, and they had a similar policy. No matter how nicely some homeless person asked, we weren't allowed to give them free food no matter how old it was. They get used to it, and keep coming back |
Why it takes so long for NASA to prepare one launch | When you spend a few billion dollars on something that you are strapping to the top of a rocket to send across the solar system, you are willing to spend quite a lot of time and money to make sure that it doesn't fail. |
Why does the moon cause waves in the ocean but not on smaller bodies of water like lakes? | The moon causes tides not waves. Tides happen when some of the water sloshes over to be closer to the moon.

Why do all of the victims of ISIS beheadings look so calm and nonchalant? | They're drugged, high on whatever ISIS gives them. They barely fight when getting their heads chopped off slowly. |
What is this new "Common Core" math? | The number line problems are ridiculous. As far as subtraction I've actually independently preferred the backwards way by adding up instead. As shown elsewhere. 235-182 for me 8- > 18- > 23- > 53 or 8+10+5+30. While carrying over can often be faster, I find this method to be more versatile. In the case of giving change... |

When governments print more new money, who gets it first (and gets to spend it before inflation kicks in)? | Government doesn't print it, the Fed does. The Fed != the government.

Do today's video games keep you playing like casinos do, throwing you wins once in a while to keep you playing longer? | Yes. It happens *a lot*. [Here is an article from Gamasutra] describing this balancing design. The example you gave - a game getting a tad harder as you get better - is just the tip of the iceberg, and it's rather easy to implement as well. It has nothing to do with data mining; they just keep record of your scores and... |
What is wrong with means testing? | Some benefits are means tested because they intend to keep an individual afloat while they cannot otherwise support themselves\u200b.

How do the companies that sponsor benefit from having game shows give away their products to contestants? | Because they can do it for much cheaper than the average consumer. For example, take phone cases. An average phone case will run you $25 to $50 in a store, but the store buys it for $18, and the manufacturer produces it for $10. So what appears to be an expensive item doesn't end up costing them near as much as you wou... |
Why helicopters and planes can't get out of the earth? | As everyone else has pointed out, once the atmosphere gets too thing, a wing no longer generates lift.

Can someone explain what it is about music theory that allows pretty much every song to be mashed with eachother in a way that fits? | Here's my version for kids: Music is like Mexican food. There are only a few ingredients that are put together slightly differently to make a different dish. The difference between a taco, a burrito, and Ensalada is just order and proportion. The difference between Bach and technical death metal is mostly tone and volu... |

Short selling. How can you make money betting against a stock? | Imagine that you go up to your friend and ask to borrow his car.

So you buy it back, and return it to your friend. That's short selling.You borrow sha... |
Why does feeling lonely make you want to spend more time alone? | Nothing confirms my feelings of alienation like being somewhere and seeing people connecting Or rather, I do but it requires so much effort.

How to understand camera lens F numbers | tl;dr The bigger the number, the smaller the hole, the greater the depth of field.

How do they build those rickety rope bridges? I can't wrap my brain around it... | Generally, they toss a line across that's light enough to be thrown the distance, the use that line to haul across a heavier line, which may be used to haul a heavier line, etc, until the line in place is strong enough. Once the initial line is across, you can use it to shimmy across with any other lines that need to g... |

How do banks know if a check has already been deposited? | This is the reason mobile deposit funds aren't available right away, and why the app tells you to keep the check for a number of days after depositing it.

What makes a great conductor great? and conversely what sets them apart from a random high school band teacher? | Good answers below, but I've found a lot of people don't really know what a conductor does. Hint: He's not just waving a stick in time to the music. Here's the thing about playing in an orchestra: You can't actually hear all the other instruments. If you're in the middle of the brass section, chances are you can't hear... |

How does a cars speedometer know not to increase when a cars tires are spinning? | Depending on the car and the age, it will determine speed either by a sensor in the drivetrain or use the wheel speed sensors. Depending which of those sensors it uses, it may or may not report the wrong speed. If a car is RWD and uses one of the front wheel speed sensors, when you're doing a burnout, it'll still repor... |
why it takes so many years for a county like Iran to build a nuclear weapon when the technology has been around for over 60 years? | meowtiger 's paper crane example is a great one. Now also, imagine the teacher has decided that it's against the rules to make paper cranes, so she's watching very, very closely to make sure that none of the other kids are doing it. As it happens, the paper used to make the crane is bright orange and very hard to hide,... |
Why do we use the base 10 system, and what are its benefits over other mathematical systems? | You want to use a system where you don't have to memorize too many symbols, but you also want to use as many symbols as possible to minimize the length of numbers you have to write Other than that, your choice doesn't really matter. There is some slight optimization you could do for mental arithmetic though, in the for... |
Why do people give Al Gore credit for inventing the internet? | See mypsychoticself's post. But read the whole thing, it's not very long.

If you read m... |
Why is Carfax, a commercially owned company, allowed to collect all kinds of information on our cars, and sell it to others for money? | Because they are getting info that is available to all.

Why is Nickelback so hated? | It's a singling thing. People with preferences single their in group status by revolting against out group preferences. It's the same how many redditors show their nonconformism by revolting against conservative politics when they usually aren't taking a status hit for that. Real nonconformism expresses itself as disag... |
If Reddit is not paying sub-reddit moderators, why are they working on Reddit, unpaid? | Because they enjoy the work they do. They like the community, and they want to see it flourish by helping it the best they can.

How far back in time can a modern English person go and still be able to converse with people before the English sounds foreign? | Slang would get incomprehensible pretty quickly, within a 100 years. To be able to manage a rough conversation, while still probably missing a good deal of nuance, you could probably hack it until about the end of the [great vowel shift] around 400 years ago. At that point vowels would start being pronounced differentl... |
Why does Reddit care so much about privacy? | Good question. You see a lot of people who seem to be very concerned about online privacy. But if there were some terrorist incident which was hatched and plotted on the internet a lot of these same people would be really angered if it turned out that the authorities were caught completely unaware. My feeling is that, ... |
Why does it take a long time for human babies to stand up/crawl but other mammals can stand almost immediately after birth? | Mammals that walk immediately at birth are usually prey/herd animals that need to be able to move with the herd. Momma zebra doesn't have anyway to carry a baby that can't walk. Animals that nest or predators take more time to develop to maturity after birth. Primates even more so. |
How could the US intervene so quickly in Libya but do nothing in response to the declining situation and recent massacres in Syria? | Gaddafi was going to start trading oil using a new African currency that was based on gold as opposed to trading using the American dollar or other fiat currency. This would have obvious detrimental repercussions for the US and the US economy and we just couldn't have that. I feel like this was a large factor in the US... |
Why is it bad to sleep with contacts on? | The clear cornea of your eye doesn't have any blood vessels, but is still made from living cells.
