v50.14 · v0.47.05 This article is about the current version of DF.Note that some content may still need to be updated. |

Topics (also Tech or Innovations) are part of knowledge.
There are around 300 innovations that can be discovered. Many of them have requirements, and many do not, so it's kind of a tech forest/grassland rather than a tree. Notably missing are innovations related to practical labors in the game (which will be added later in development).
Several innovations require innovations from other branches, and since all knowledge is individually tracked, that implies some investigators will need to be at least well-read if not skilled in various topics (there aren't currently joint research projects). There are some old and new mechanisms in place to ensure this happens.
There are 9 "branches" of the knowledge system.
Astronomy

|---|---|
| The process of surveying land | |
| The forces that govern wind patterns | |
| The process of economic data collection | |
| The placement of economic information on maps | |
| The construction and use of the surveying staff |
The geography innovations include several related to cartography.
History
Innovations for historians are, in part, writing forms like biography, and then any historian that reads a biography can start writing them as well. Innovations include comparative biographies describing multiple people, and matters of sourcing, etc.
Historians can start to understand how cultural differences and state bias affects source reliability and think a bit about social forces.
| Topic | Description |
|---|---|
| Archaeology | The method of collecting and evaluating artifacts to learn about history and culture |
| Cultural History | The method of accurately and comprehensively describing cultures and civilizations" |
| Source Reliability | The reliability of sources |
| Personal Interviews | Using personal interviews as sources |
| Autobiographical Adventures | The method of writing a biography of oneself, particularly as it concerns a military campaign or adventure |
| Discourse on the cause of historical events | |
| The method of writing the history of a single individual | |
| The method of comparing and contrasting different cultures | |
| The role of cultural differences in source reliability and interpretation | |
| The compilation of brief biographies into one large collection | |
| The compilation of family lineages and methods of displaying them artfully | |
| Compiling several biographies to compare and contrast the subjects' character and to gain insight into history | |
| The exploration of how history would be different if some key past events had transpired differently the notion of historical, governmental and social cycles | |
| The notion of historical, governmental and social cycles | |
| Historical Causation | The causes of historical events |
Mathematics
| Topic | Description |
|---|---|
| Positional Notation | |
| Large Sums | Simple formulas for certain arbitrarily large sums |
| Equations | The technique of balancing and completion for solving equations |

Natural science
Toady on natural science innovations:
And so on through the other seven branches - there are innovations in naturalist writings, for example, and then they can investigate specific critters with those in mind when they get down to work observing foraging behavior or performing dissections.
Naturalists can build a theory of rainbows using water-filled spheres and a camera obscura, and they can calculate the height of the atmosphere based on atmospheric refraction using the law of refraction (though it tries not to get into the actual shape of the world, since that might vary).
| Topic | Description |

| Physical Features | The classification of creatures by their physical features |
| Climactic Adaptation | The way that creatures are suited to the climates in which they live |
| Migratory Patterns | The migratory patterns of creatures |

| Foraging Behavior | The foraging behavior and diet of creatures |
| Reproductive Behavior | The reproductive behavior of creatures |
| Social Behavior | The social behavior of creatures |
| Dissection | The dissection of creatures |
Philosophy
The specific view that a philosopher takes on, say, the nature of beauty or methods of education will depend on their individual/cultural values, where they apply, and a philosopher that encounters a philosophy book on beauty can then provide their own take (having acquired the innovation).
Toady on philosophy innovations:
For fields like philosophy, I've tried not to make judgments about which ideas are "right" or anything like that, but rather which subjects can be thought about at all.
