Why do we suddendly lose motivation when close to finishing a task? The last 20% is always the hardest to me. | I've seen it described as a 'fear of finishing', related to worries about having nothing to do afterwards and fears about being unneeded.

Why isn't it a good idea to purchase a single lottery ticket to win the super lottos that come around for hundreds of millions of dollars? | I have two views on lottery tickets. 1. Let's say you buy a $1 ticket everyday for a jackpot of $10,000,000. You're life is not going to be affected much by losing a dollar a day which only sums up to $365 a year. For a working class, that's not that much. Literally just vending machine money. However, if you just so h... |
Why can we randomly feel our pulses in parts of our body for a few seconds? | Medical student with my cardiology exam this monday. This is called a [Pulse Pressure Wave], and is due to the pressure generated by the heart during systole.

how do the gills on a fish filter out the oxygen from the water? | Fish don't break the H2O of water apart to get at the oxygen that's in the water molecules themselves. That would require more energy than is produced by using that oxygen later in its metabolism.

Breaking surface tension didn't help at all, as your body still has to deal with a hitting a significantly dense medium that your body has to displace at high velocity.Still fatal. As I understand it, the deceleratio... |
Why does water appear to be white when coming down from a tap really fast or a waterfall? | Almost any clear substance with a different refractive index than air will look white if broken up into a lot of small bits. Take water, foam a bunch of air into it so it's essentially a bunch of tiny water pieces, and it will look white.

Where would air go if you would release some in space? Eli5 | When something like that happens, the ejection of the air from whatever container its in into space is going to cause the air particles to travel with a certain velocity.

How does download / upload speed affect online game play-ability? | The download speed doesn't affect your gaming experience unless it's abysmally slow. Usually you don't need more than half an Mbps.

Before you let your kid out on the internet, make sure you teach them how to use it in a ... |
I'm concerned that ELI5 is essentially becoming AskReddit | I think that the complex explanations are caused by people trying to explain this to a hypothetical five-year-old.

Why is it that when my computer is doing something, the "time remaining" estimate fluctuates so much and is rarely accurate? | A decent analogy would be how long it will take to drive somewhere. You know how far it is and you know how fast you are going at any given time. But you can't predict the traffic you'll run into on the way.

why don’t we make coffee like we do tea, by seeping the grounds in a bag? | I would argue that a French press is pretty similar to the way we make loose-leaf tea. As others have said, the tea leaves need more contact with the water so a drip-type coffee maker wouldn't work with regular tea. |

We have a numbe... |

What stops underground sewer water from freezing during outdoor sub-zero temperatures? | Pipes do burst in extreme cold sometimes, but generally the frost line doesn't extend very far underground. Once you get more than a few feet underground the temperature doesn't really ever stray very far from the long term average, which for most places people actually live is above freezing. |
Why are hospital buildings (in the US) generally built taller than surrounding city property? | I always think of hospitals like air craft carriers, where the whole reason the ship exists is to put 24 pilots within striking distance of their target. Everyone else on the ship is literally support for those pilots. Hospitals are similar. You have all this infrastructure to support a few Dr's. But their patients nee... |
What determines the ending of road names? (Ave, St, Rd, Trl, Blvd, etc...) | In a lot of municipalities, the direction the street runs also has something to do with it.

How are terrorist attacks still happening despite NSA blanket collection of communication data? | There isn't much of a concept behind this. How do people speed on the freeway with all the cops? How do people download movies and music with the riaa and mpaa monitoring sites? Because they can't watch everything all the time, some communication is done in person only or using innocent sounding code words. |
Why can't you pick up a bullet and put it back in your gun and shoot it again? | If the bullet is out of its casing, then there's no gunpowder to propel it. It's just a piece of metal with no primer or gunpowder. |
How can something be "more hydrating" than water? | No no. All of these posts are missing the main reason why glucose and sodium are added to rehydrating drinks. Its not just about osmotic gradients. It's about glucose and sodium channels being coupled with the gates that allow water absorption in your GI tract. If you want to maximize absorption of water after whatever... |
