  • It’s not just that the phenomenon isn’t familiar to my experience, it doesn’t even theoretically correspond to physics as I understand it. Probably you know the things I’m about to say and are speaking informally, but for clarity and to establish common vocabulary I’m going to nail some stuff down according to science.

    You can’t see water in its vapour form. You can see when vapour condenses back into tiny liquid droplets in midair (fog, mist, or colloquially “steam” but not really steam) or on cold surfaces (like when it fogs or “steams up” a mirror).

    Water vapour can’t carry substances with it when it goes through the phase transition from liquid to vapour. Anything that is dissolved in the liquid water remains behind as residue. When water vapour condenses back into liquid, it is pure water. This is how distillation works. Piss is just water with stuff dissolved in it. If you evaporate piss and then condense the vapour in a separate container, you get pure water.

    (Things get complicated when there is something dissolved in the water that has a similar vapour pressure, like alcohol or solvents, but those shouldn’t be present in your urine.)

    I think maybe you just have pee that has an unusual or unusually strong odour, and the hot, continuously agitated water makes the smell more obvious than when you use a toilet or urinal. But the scent doesn’t mean you are being bathed in piss vapour, it’s just a normal smell.

    This is probably a problem with how the question is being asked, but…

    A .py file is not an application. It might be a component of an application but there is no general way to “install” a .py file. If you are coming from microsoft, you can think of a .py file as similar to a .bat file, but it might also be more like a .dll file.

    If the .py file contains a script meant to be run like a .bat file, you can to run it from wherever you saved it using the Python interpreter. That is what is occurring in this example from your page:

    python3 rectarg.py R230122W.cht R230122W.txt output.tif --target_dpi 300 --background GS10 --label_axis_visible X=B

    The user is using the python3 command to run the rectarg.py script from the current directory, and passing it arguments with the rest of the commandline. This doesn’t require installing rectarg.py, just knowing the path (or in this case, being in that path).
