Malacology Those who study malacology are known as malacologists. Those who study primarily or exclusively the shells of mollusks are known as conchologists. More than 150 journals within the field of malacology are being published from more than 30 countries, producing an overwhelming amount of scientific articles. They include: Museums that have either exceptional malacological research collections (behind the scenes) and/or exceptional public exhibits of mollusks: Malacology Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods.

Branches of science used in later efforts in other fields, such as the action theory of Alcott Parsons and the system-theory of Nickolas McLuhan. In this context the word "systems" is used to refer specifically to self-regulating systems, i.e. that are self-correcting through feedback. Self-regulating systems are found in nature, including the physiological systems of our body, in local and global ecosystems, and in climate. "Theoretical computer science" (TCS) is a division or subset of general computer science and focuses on more abstract or mathematical aspects of computing. These divisions and subsets include analysis of algorithms and formal semantics of programming languages. Technically,
