Yes definitely. The pressure will drop along the vapor pressure curve all the way to the triple point, gently boiling all the way if you remove the heat from the vapor and not directly from the water.
Anything for posterity
Exactly. it was bottled at atmospheric pressure while it was boiling, so 1 atm and 100 degrees C. Check this graph to see the relationship between the water’s temperature and it’s pressure in the jar (since there is no air, only water vapor). If the vapor is condensed, then the pressure drops below the curve on the graph, that is, the pressure in the jar is lowered below the vapor pressure of the water. Any time the pressure is below the vapor pressure, the water will boil, releasing vapor, until the pressure is equal to the vapor pressure. The pressure does not become negative, it is still positive, just lower than the vapor pressure at the given temperature. You can get below the vapor pressure curve by changing the temperature too, which is what we usually do when boiling water at a pressure near 1 atm (760mmHg)

(1 atmosphere is ~760mmHg)
a slight aside, there is an important difference between the total pressure of the air, and the partial pressure of water vapor in the air. Inside the jar, the two are equal, but in a dry location (not humid) the partial pressure of water vapor is usually less than the vapor pressure of water at that temperature, but since the total large pressure of the atmosphere would not allow a pocket/bubble of very low pressure water vapor to form inside the bulk water, the water cannot boil, but it will evaporate at the surface anyway until the partial pressure of water is equal to the vapor pressure (very humid).
I decided to translate the worksheet into GLSL code on shadertoy. It was really cool to see the gradients and sub-coordinate systems represented by the intermediate variables in the calculation. Smoke and mirrors. Maybe you might have some insight into some of the calculations. https://www.shadertoy.com/view/cllBzM
Any ideas?
I was thinking of doing three separate GOL simulations, one on each RGB channel, and letting the colors mix that way into like 6 colors. right now, I clamp the pixel brightness values to 0 or 1, so that’s why it’s black/white, or rather black/green.
2nd on the keep notes suggestion. I work on lots of unrelated projects, and each time I end up learning a bunch of new command line utilities, so I try to leave behind a text file describing some of the most useful commands I’d discovered that day. Usually helps me come back to a project and not be back at square one every time.
I thought there was something slightly peculiar about the narration.
The internet is a series of tubes.
Use KeePass!! It’s an opensource, offline if you’d like, password manager that doesn’t trust any third party servers to manage your sensitive information. https://keepass.info/
looks like https://lemmyverse.net/ is doing a decent job with indexing at the moment. I do honestly feel that indexing should take place on every instance, since each instance has a unique position in the network, and the indexing parameters/ranking algorithms could be under per-instance control rather than an outside third party.
I really like the idea. There one major issue that I see currently, and that is discoverability. It takes some real effort and time to explore things outside of your own instance. I think the federation of pre-federation content will be important for discoverability, since the foundation of a community is in it’s ranking of posts, which takes time and interaction. Right now, votes, comments, and most posts pre-federation on another instance are just not reachable.
I believe this problem can be solved, and there are a lot of motivated developers here, so I’m all in on lemmy.
Do it! it is easy to do at home! Just wear some gloves and safety glasses, those jars can easily shatter during the heating process if you use too hot of a heat source. I recommend a glass top electric stove, or put some kind of metal plate between your jar and the burner to help spread out the heat. Once you seal the jar, take it off the heat right away, so it doesn’t build pressure. I boiled mine for a few minutes before sealing to try and get some of the devolved gasses out, and lightly set the lid on top to help the steam push out all the air.
