LINDA? What is LINDA? 
LINDA is our atmospherics system. There are various theories on the origin of this name, but that is not why we are here. We are here to understand how gas dissipate, how pipelines and eventually pipenets are formed, and the more technical parts of atmospherics.

For a technical breakdown of our atmospherics subsystem and how everything works, refer to https://github.com/tgstation/tgstation/blob/master/code/modules/atmospherics/Atmospherics.md

==Pipeline and Pipenet Theory==
If there is one part of Atmospherics 301 that you should read, this is it.

Our pipes does not simulate flow. Every interlinked pipe is combined into a single pipeline, and every pipeline member is subject to gas sharing. <b>This gas sharing is instantaneous</b>. Lets take the picture on the picture to our right as an example. The gas from the canister will immediately appear on the first node of the volume pump because both of them are connected through the same pipeline, even if the pipes are ten, twenty, or a hundred times longer. As long as two things are part of the same line they will equalize instantly.

<b>The amount that each part of the pipeline gets in the aforementioned gas sharing process is determined by their volume.</b> The first node of the gas pump will get 200/(210+1000+200) of the gas present in the pipeline, the pipes themselves will get 210/(210+1000+200), and the canister will get 1000/(210+1000+200). <b> Most atmospheric devices perform actions only on the gas directly present in their nodes.</b> The pump will only be able to pump this 200/(210+1000+200) portion of the gas allotted to it to the second node. The pipeline will then redo the gas sharing, just with less gas in it (because a part of it has been pumped away), and the process can repeat again.

This means that for bigger and bigger pipelines, each machinery will have a smaller and smaller share of the total volume and will be able to perform work on less and less gas. This is why taking gas out of the huge distribution loop is tedious and long, this is why some supermatter setups will lack moles directly inside the chamber if you expand the cooling space loop too much, this is why thermomachines are less reliable on very huge pipe networks.

==LINDA: Active Turfs and Excited Groups==
Our atmospherics system: LINDA, work based of concepts of active turfs and excited groups.
A turf (tile) will become active when any gas changes happen, be it a plasma canister being opened, a breach occuring, or as simple as scrubber taking CO2 out. A turf will also become activated if a wall is deconstructed, necessitating it to be filled. These active turfs will combine into an excited group and equalize every several iteration of the subsystem ticking. This is LINDA in it's simplest, most abridged form.

==Superconduction==
On high temperatures, superconduction occurs. Superconduction transfers heat between gases in the air and the objects in the world, most notably floors, windows and walls. If these objects are too hot they will break or melt.

Another very visible effect of superconduction is on super hot turf based fires (incinerator springs to mind). Reinforced floors have the temperature of 20 degrees Celsius and a very very high heat capacity. This means that these reinforced floors will almost always never move their temperature and stay at 20 degrees. Very hot gas mixtures on top of reinforced floors will constantly try to share heat with the floor and lose energy. <b>In other words, reinforced floors constantly cool your fires down.</b> This makes reaching very high temperatures on turfs very difficult.

It is possible to try and circumvent this phenomenon by burning things inside a canister or pipes.
