Why can't you leave a baby alone? | [
"It? Nothing. Which also puts it at a lot of risk if say, your house catches on fire. Or if it does manage to roll over or get a limb stuck in between the crib slats. And yes, you are going to say 'but I am only at the store for five minutes', but you cannot guarantee that. Something might happen at the store that ... | [

Why english words are written and pronounced differently? | [
"Because languages are not designed. They evolve naturally. Any dynamic system that evolves over time is prone to fall into local minima - which is a fancy way of saying, it tends to make mistakes and then _stick_ with those mistakes even when there's a better way of doing things."

Most animals lick their fur to clean it. So, how come they don't get their mouths full of fur which would be extremely annoying and uncomfortable? | [
"Yes, they do. Cats vomit balls of fur every now and then. Their tongues are different than human tongues and probably don't *feel* it as gross and annoying as you imagine."
] | [
"It's a counter-intuitive reason - it's *because* they lick themselves all day. Cats have very abrasive tongues covered with small spines pointing back toward the throat, which serve as a mini-comb when licking upwards (which you may notice your cat always does when licking itself.) Your average indoor cat won't h... | eli5_question_answer | {

LSD and other psychoactive drugs are known for their visual hallucinations. What would happen if a blind person were to experience these hallucinations? | [
"It would depend why they're blind. LSD plays with the thalamus, the part of the brain responsible for deciding which signals go where. If someone had a functional visual center and damaged eyes, they would experience vivid daydreams of visual phenomena that aren't quite as realistic as sight. If they have a damage... | [
"If the dose of any psychedelic is high enough, you lose connection with reality through traditional means. If your brain is visual and creative enough, this is where you can get full blown hallucinations. Personally I've only had them on DMT"

The Reality of Gravity Versus The Sensation | [
"We don't directly perceive the deep physical reality of *anything.* We can't see that light is photons. We can't tell that heat is vibrating molecules. We can't feel that digestion is acids dissolving our food. We can't tell that an electric shock is electrons. It's no different with gravity. We perceive what our ... | [

Is washing dishes under hot water (but cool enough not to burn you) actually more sanitary than washing in cool/cold water? | [
"The simple answer is yes. By raising the temperature, you kill off bacteria that only thrive at lower temperatures. However, the practical value of this isn't all that significant. Unless the heat is quite high and the dishes are exposed to the heat for a longer period of time, you won't kill all the bacteria."
] | [
"It may be too hot to shower in, but it's the temperature needed for washing dishes/clothes/etc. There are plenty of uses for hot water besides washing your body, and some of those uses work better with very hot (hotter than you can stand) water."

Why do we only name an element after it is synthesized when we knew it could in theory exist? | [

"Try everything they could think of break it down, and see if any of them worked.

In a cellular network, is each channel specified for each user? Can there be multiple users on the same channel without any interference? How do telecom companies assign a specific bandwidth to all of its customers? | [
"No, each user doesn't get a dedicated channel. Each phone jumps around a wide range of different channels from moment to moment, in a synchronized dance along with the tower it's talking with. The tower attempts to balance the bandwidth needs of all the phones it's currently handling."

"The A in ADSL stands for Asymmetric. The common need for most is that you download much more than you send, mostly getting a big number of data packets, whilst sending only a few small packets that acknowledge the data.
