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). Only the discovery of certain "form" type topics has any effect on gameplay, as it allows scholars to write new types of books; star charts, atlases, dictionaries and various historical forms.
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. Each branch is further divided into categories of topics, such as methodologies, theories, etc.
