[NSFW]Does the Quran really say this? If not, how is it being interpreted by ISIS? | [
"I don't have an answer for you, but the New Testament does not, in any way, condone what happened in the Crusades. That was a scenario where a bunch of people thought they were doing good by attempting to recapture the holy land, then found Bible verses to \"make it okay\""

"I'm not sure what you know about the terrorists and radicalized Muslims but believe it or not Islam does not approve of their actions.

What makes computer hacking difficult, and not something a computer itself does? | [
"Well in some cases, it does. But that's another story. Consider what computers do: very simple tasks, *very* fast. They don't (usually) screw up. Now hacking consists, fundamentally, of finding cases where people told the computer to do the wrong thing. At a very basic level, this is a deviation from expected beha... | [
"Missile launch systems are not connected to the Internet. That would be really stupid to do, for precisely this reason. But also, hackers aren't nearly as good as you think they are.

Why do some biscuits take longer to completely soak if completely covered by liquids instead of slowly dunked? | [
"When you dunk the biscuit, the tea replaces the air inside the biscuit. The air has to be able to escape the biscuit for this to happen. This is easy if part of the biscuit is still dry, because the surface is porous. But when you completely dunk the biscuit the porous surface is covered by tea, which resists the ... | [
"Bread has a lot of moisture (google says 40%). So, leaving it out leads to the liquid evaporating out and drying out the bread. Crackers have very little moisture, that's why they can last much longer than bread. So, when you leave them out, they absorb the moisture from the surrounding environment."

What is a Jehovah's witness? What's that all about? | [

How do us humans know how to have sex? | [
"If nothing else, experimentation with sticking one thing into another and having it feel good.

Why, if I live in Jackson, MS, my Amazon package went from South Carolina to North Carolina (the opposite direction). | [
"Not if it had to have it's own truck to do so. Most of the carriers use a \"star and connector\" model for delivery. For a long time, every fedex package that left it's \"region\" was routed through TN because this simplified logistics and made economic sense. Increased volume has allowed for more local replicatio... | [

Why don't cars sound like the explosions in their engines? | [
"Because cars have a longer exhaust pipe, which may be wrapped in insulation (near the headers) and the engine is usually kept in an engine compartment that's often insulated as well. Finally the exhaust pipes are connected to a muffler and catalytic convertor. All of that helps suppress the sound of the engine. A ... | [

Why are Pit Bulls a more dangerous and unpredictable dog compared to other breeds? | [
"They're not. Unfortunately, a fairly large majority of pitbulls are located in lower-class, poverty stricken urban cities/neighborhoods. This could be because they have a large build compared to other breeds. But, because these dogs are usually trained to \"protect\" and \"intimidate,\" it's just a case of classic... | [
"Two reasons - the first being that most people don't feel the need to train smaller dogs since they're easier to just pick up and move around. A well trained dog will stop barking when you tell it to. The second reason is that some breeds are more aggressive than others. Most small dogs do tend to be aggressive, b... | eli5_question_answer | {

Why does smoking cigarettes make my hangover seem a thousand times worse? | [

"Because God want to punish you with cancer for sinning. Just kidding, it's probably because alcohol changes the way sensory information is processed in the brain and makes everything more likable. Smoking is better, crappy food tastes better, ugly girls look better, etc."

when resetting electronics such as a wireless router, why does the amount of time matter with regards to unplugging the device? | [

Why does a single repeating drip of water drive us crazy when a small trickle of water does not? | [
