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

Topic Description
Geocentric Model The theory that the sun moves around the world
Daylight And Seasons The variation of daylight with the season
The relationship between the lunar and solar year

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
Historical Causes Discourse on the cause of historical events
Biography The method of writing the history of a single individual
Cultural Comparison The method of comparing and contrasting different cultures
The role of cultural differences in source reliability and interpretation
Biographical Anthology The compilation of brief biographies into one large collection
Genealogy The compilation of family lineages and methods of displaying them artfully
Biographical Comparison Compiling several biographies to compare and contrast the subjects' character and to gain insight into history
Alternate 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
Cyclic History 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
Very Large Numbers Notation for very large numbers
Nothingness A symbol for nothingness

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
The origin of rainfall through evaporation and condensation

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.
