"A large part of accents is the pronunciations of various sounds, the stress patterns of words and the 'rhythm' of sentences. The last two are lost when singing, generally, because songs have their own stresses and rhythms that take precedence. The pronunciations of vowels and other stuff *is* kept in song, but the... | [

Why is coffee such an expensive rarity in a lot of sci-fi movies set in the future on Earth? Are we running out of coffee? | [
"Coffee is grown, we will never run out realistically. Coffee is seen as a staple drink and is very important culturally, many people can not get through the day without their coffee in the morning. One way that sci-fi writers can make a universe seem very dystopian is by taking something that we consider a necessi... | [
"We aren't running out of natural resources. That used to be an argument for environmentalism, but it died in the 70's or 80's with studies that showed there's tons of oil left in the ground and plentiful natural resources for a long time. The problem is that we are destroying our global ecosystems with fossil fuel... | eli5_question_answer | {

What exactly is a "Mhz" when talking about CPU's? | [
"Basically the MHz is the amount of instructions that can be executed per second. M stands for million, so a one megahertz processor can do a million instructions per second. G is billion, so a gigahertz processor can do a billion istructions per second. The main purpose of overclocking is to increase the hertz co... | [
"Numbering is just a nice way of differentiating the new cards from the old cards. Occasionally it switches. For instances, years ago, NVidia was making cards with thousand series (4XXX up to 9XXX). Then for some reason, they decided not to do 10XXX and started with hundred series (2XX up to currently 6XX). As for ... | eli5_question_answer | {

If I buy a bottle of $10 wine now and save it for 20 years, does it become a rare and expensive wine? | [
"No. Aging wine in the bottle does nothing to improve quality and seldom does anything to increase its value."
] | [
"To me more expensive wine is noticeably better than cheap wine, but there is definitely diminishing return in quality the more expensive it is. For example, a 20 dollar bottle of wine is generally a lot better than a 10 dollar bottle. A 50 dollar bottle is better than a 20, but not that much better.

With the rise of digital distribution, why is a rating of Ao/NC-17 for a non-porn movie/game rated still seen as a kiss of death? | [
"Certain countries, like Germany, are very strict when it comes to what gets released in their countries. An AO/NC-17 game might have to be censored, or even blocked from release. That is a significant loss of sales. While digital distribution can help with this somewhat, its still pretty bad if your game is banned... | [
"In the US, originally, the rating system had an \"X\" rating for movies that either did not meet criteria to be rated at \"R\" (which was meant for mature audiences and not for children) or not rated at all. Few movies took the \"X\" rating because it meant that most theaters would not distribute the film, making ... | eli5_question_answer | {

How come car's MPG doesn't seem to be getting better over the decades? | [
"Cars today have, on average, better fuel economy than they did 20 years ago. The improvement isn't as dramatic as you might expect because they've had to increase weight to meet modern safety standards."
] | [
"As for the latter question, some cars have a display that uses information from the cars sensors to estimate fuel efficiency. But you can also measure fuel efficiency by using the car's odometer (easy if you use the \"trip\" function) and assuming that a gas station pump fills the tank to the same level if left to... | eli5_question_answer | {

Why does the taste of something diminish rapidly? Example, swirling a fruit yogurt drink around the tounge quickly becomes tasteless, yet swallow and immediately take another sip and it is bursting with flavor again. How is the taste sucked out? | [
"It's called neural adaption. You are sensitive to changing stimuli. Constant stimuli are filtered out by your nervous system. All of your senses have this quality. For instance, your eyes constantly move even when you're looking straight ahead in order to negate this. Otherwise, your vision would fade just like th... | [
"A huge percentage of \"taste\" actually occurs through the olfactory receptors (smell). Particles move more quickly when that are hot and can be more easily received by the nose. We are able to detect more flavor when food is hot. This is why icecream tastes sweeter the more it melts, our nose can start picking up... | eli5_question_answer | {
