Dwarven Academy of Science: The New Knowledge Center
« on: December 27, 2013, 01:37:36 am »

This post is intended to be a compendium of community research and science projects, with a probable bias toward recent topics. I intend to update this post from time to time, as new projects come out or as I become aware of older ones. This compendium is incomplete at the moment (as evidenced by the fact that the "personal projects" section is 40% of the post), so if you see anything you want to see here, please tell me!

As this post is an outgrowth of several requests for a compendium of my personal projects, I have included a prominent section to show off my own work.

I looked into this but didn't pursue investigation of it's finer details.

!!SCIENCE!! on mechanics, casting and accidentally the whole pathfinding

The pathfinding effects seem to have the most promise. I read some post where the OP had problems with cast-in mechanisms becoming unsupported but I suspected it was due to them being built on top of dfliquids'd obsidian which seems to do some weird things especially (or at least) In Ocean biomes.

Happy new year!

Ahhh.. the treegrowth experiment. Proof that negative results are valuable to science! (Eat your hearts out out michaelson and moorley!)

That was a fun and easy experiment.

I really do want to revisit it concerning growthrates of cavern mosses though.
Until DFHack gets better tools, I can't reasonably get that though.

(Don't suppose I could bribe quietust or DaVinci to make me a dfhack scriptlet to count grasses over a range, could I? As long as it isn't *too* costly, I might be coaxed into offering some form of financial or material compensation for the request. Does not need to be fancy. Just needs to report number of grassy/mossy tiles, and their densities over a ranged selection using the look cursor. If either is interested, the can PM me a price and preferred method. No pressure though.)

Perhaps Zivilin could elaborate, but I found this post (from another thread) very useful with regards to experiment design:

This is a seminal piece of research! I think the methodology presented here should be a model for future investigations, where possible.  This work and its method:

1. Allows for a control group, which can be used to determine the significance of the results.
2. Avoids feedback problems inherent in having experimental groups with different equipment fighting each other. 
3. Gathered fine-grained data (# bolts used) rather than less precise binary data (dead/alive), providing superior statistics.
4. Was transparent and easy to understand, so the results were clear.
5. Discusses its weaknesses and limitations.

What I've learned:

1. Run a few controls to determine variance.
2. Each experimental group should perform identical tasks, i.e. face identical enemies.
3. Consider the type and quality of data gathered. Perhaps time to kill, or number of dead enemies after a given amount of time, etc.
4. Presentation is important.

Science is more than just setting things on fire for lols.

Maybe 1% or so, yeah. Mostly still setting things on fire.

Perhaps Zivilin could elaborate, but I found this post (from another thread) very useful with regards to experiment design:

[...]
1. Run a few controls to determine variance.
2. Each experimental group should perform identical tasks, i.e. face identical enemies.
3. Consider the type and quality of data gathered. Perhaps time to kill, or number of dead enemies after a given amount of time, etc.
4. Presentation is important.
[...]

Every project has its own nuances. In general:

1. Familiarize Yourself thoroughly with the researched subject. Decide on exactly what You are setting out to prove/disprove.
2. Think long and hard on what types of parameters/data will conclusively prove/disprove Your hypothesis.
3. Design an objective experimental setup.
4. Identify all conceivable variables that may influence Your setup, and modify the setup to eliminate them. Repeat until satisfied that all variables are eliminated, or at least accounted for.
5. Ascertain that Your results proved/disproved Your hypothesis. See if any other interesting research byproducts can be extracted from collected data.
6. Present the results in a clear manner, to the best of Your abilities.

And while I'm posting, I believe Modding material properties vs. how the properties are used by the game has a place in this compendium, possibly under a new "Game Mechanics" subsection. It has a treasure trove of material and combat mechanics-related information, forum-exclusive.

Updated the OP to include everyone's suggestions, plus a couple other things. I decided to add the "modding material properties" post to the "Military Science" section, since weaponry/armor/combat is the primary (almost the only) practical application of material science.

Sooner or later, I'll probably have to come up with some guidelines on what I can add to the OP, so it doesn't get to be overwhelmingly long. I'd like to have some quasi-objective criteria, if possible. Any thoughts?

I think this belongs in here:

http://www.bay12forums.com/smf/index.php?topic=129994.msg4620472#msg4620472

It is a method for digging through a 2 layer aquifed with nothing but a pick and without exposing to the surface. I've successfully applied the method, e.g. here: http://www.bay12forums.com/smf/index.php?topic=133272.msg4815920#msg4815920

I re-checked since i was casting obsidian anyway, and mechanisms that get cast in obsidian generally become "hanging" and can no longer be supported from above or below. Unless you dig them out, obviously...

The "k" menu doesn't show this, you have to "q"uery them. They'll remain responsive to power and switch signals and will not immediately deconstruct, but if e.g. you build and remove a connecting axle, mechanisms try to pop out of the obsidian (and will get crushed if there's no open space on the same z-level nearby). The concept would be to cast the mechanism or axle into obsidian, then remove the casing and build supporting/connecting machinery. Transporting power through walls should work this way, as long as the support isn't entirely made up of gearboxes that get disengaged sometimes.

This was properly cast obsidian, i don't do dfhack.

On the other hand, !!SCIENCE!! is literally on fire. It's important to state the distinction between the two when posting - you could save lives!

EDIT: We really should have a seperate science subforum.
