Polar semiotics is a theoretical framework in semiotics, the study of signs and symbols and their use or interpretation. This framework was notably developed by the linguist and semiotician Algirdas Julien Greimas. Polar semiotics focuses on the relationships between opposing elements in a sign system. At its core, polar semiotics suggests that meaning is constructed through a system of oppositions or binary pairs—such as presence/absence, good/evil, culture/nature, etc.
The year 1954 is significant in the history of computing for several reasons, particularly due to the development of programming languages. One notable event is the introduction of FORTRAN (short for "Formula Translation"), which was one of the earliest high-level programming languages. Developed by IBM for scientific and engineering calculations, FORTRAN made it easier for programmers to write complex mathematical expressions without needing to deal directly with machine code.
The Brusselator is a mathematical model used to describe a reaction-diffusion system, particularly in the context of chemical kinetics. It was introduced by the Belgian physicists Ilya Prigogine and his collaborators in their studies of nonlinear dynamic systems. The Brusselator model is a simplified representation of autocatalytic reactions, where the autocatalytic processes lead to the emergence of complex behaviors such as oscillations and pattern formation.
Robert K. Logan is a Canadian scholar, author, and researcher known for his work in the fields of media studies, communication, and the history of technology. He has been influential in exploring the relationship between language and media, as well as the impact of technologies on human communication and culture. Logan is particularly noted for his theories related to the interplay of the medium and the message, building on the ideas of Marshall McLuhan, a prominent figure in media studies.
