What is a Pineal Gland, DMT, medically real or just stuff coming out of fake imagination. | [
"The Pineal Gland is a small gland in the brain that primarily produces melatonin, a chemical used by the body to regulate sleep and act as an antioxidant for the nervous system. I assume you mean the drug DMT, which is a psychedelic drug that is structurally somewhat similar to melatonin which is present in very s... | [
"Many great scholars have asked the same question. A group named Haddaway was exploring that very question themselves. Back in the '90's there was an entire institution devoted to the question known as The Roxbury. There were no conclusive results. No real signs were found. Is it a chemical reaction?

In terms of internet speeds, why are download and upload speeds so different? | [
"The reason for the difference is that most people download more data than upload. When you visit a page, the page sends you a lot more data then you send it. On the flip side, the web server needs a stronger upload speed as it is sending files places instead of receiving them mostly. The biggest upload speed need ... | [
"Your connection is capable of a high speed, such as the one reported in the speed test, but that does not guarantee that other services will always provide that speed.

Why is it so hard to hear lyrics right? | [
"Often sole audio queues are hard for the human brain to interpret as a majority of our communication is at least two fold: auditory and visual. Without lips to follow it’s super hard to know definitely what is being said, especially when the lyrics are ambiguous or muddled in the first place. Brain Games did a seg... | [

Why are glasses always drier than plastic cups after the dishwasher's done? | [

"They run the pump one way when circulating the water to wash the dishes - this way round it sucks water against the filter.

why do airplane flight tracks always make big arcs, rather than a “straight line” directly to your destination? | [
"Because the earth is round and what you're seeing is a projection on a 2D map of the shortest path on a sphere (the Earth)."

"Anyone that travels from point A to point B without turning left or right is using a great circle route. Great circle is just a way to describe what a direct route looks like on a flat map.

why is it then when you repeat a simple word over and over sometimes it’ll all the sudden sound almost foreign coming out of your own mouth? | [
"It’s called semantic satiation. With repetition, the neural pathway specific to the word becomes fatigued. These pathways are what connect signifier (word) to signified (meaning). So when the pathway erodes, the words become gibberish."

Why does it seem as though big movies with similar plots/themes are often released at the same time? | [

"Because the small budget allows for even bad movies to still turn a profit.

When charging anything, how does it know when it is full battery and to stop charging? Also what happens when you keep something plugged in on full charge? | [
"It depends on the battery type. For lithium cells, the charger usually turns off when the charge current drops below some threshold, typically around 3 % of rated capacity or if the current drops to a steady value. For longest lifetime, it is advantageous to terminate charge on lithium cells before they reach the... | [
"If there is nothing plugged in, then no it will not use any electricity. For electricity to flow, there must be a complete circuit, and to complete the circuit you must plug something in. Some devices draw current even when they are off if they are plugged in, that may be what she is thinking of."

How do explosives function? | [
"Explosives essentially are a very violent chemical reaction. The explosive burns at a very rapid rate, and that creates an area of high pressure, on the detonation point, which expands into the area of low pressure around it (the air).

Why are updates to video games so large, sometimes larger than the game itself? | [

How are nuclear bombs tested without having devastating effects on the environment? | [
"Test sites are radioactive for a time, but they are kept as far away from civilization as possible to limit contamination. It also depends on what kind of test it is.
