What's the reason most trains don't know their assigned tracks until right before arrival when most planes have assignments up to a day in advance? | I think Its because they only can go on certain ways where are railroads, and If only one is late, then the whole thing is messed up .

What exactly am I downloading/uploading on a speedtest? | I've looked into this. I was not able to recognize a file format. Here's how I'd do it: DOWNLOAD TEST: I'd make sure the client pulls data and then deletes it quickly.

We can recognize that this distortion has a shape and we see the glass. This is also why a perfectl... |
Let say we dig hole into earth, how is the atmospheric pressure down there? | Atmospheric pressure increases with depth, just like it decreases with altitude, because you have more air above you pushing down. However, you'd have to have a pretty deep hole to feel any noticeable effects - to feel 2 atmospheres you'd need a hole nearly 4 miles deep, because air is relatively light. Contrast this w... |
Why do some songs or events give you the chills? | /r/asmr should give you a good example of sounds, /r/frisson should give you good examples of music that cause this phenomena EDIT: Never actually answered the question, there's not enough research on the topic yet.
