Hybrid quantum dynamics explores the interaction and evolution of systems combining both quantum and classical degrees of freedom, offering a way to study complex phenomena that can't be fully captured by either quantum or classical mechanics alone.
Constructor theory expresses physical laws exclusively in terms of which physical transformations, or tasks, are possible versus which are impossible, and why.
Information science is, or should be, involved with the whole concept of knowledge
in whatever form its manifestations may take.
Jesse Shera (1973, 286)
Apparently, there is not a uniform conception of information science. The field
seems to follow different approaches and traditions: for example, objective
approaches versus cognitive approaches, and the library tradition versus the
documentation tradition versus the computation tradition. The concept has
different meanings, which imply different knowledge domains. Different knowledge
domains imply different fields. Nevertheless, all of them are represented by the
same name, information science. No wonder that scholars, practitioners, and
students are confused.
Chaim Zins (2007, 341)
The chunky concepts which make up our field’s intellectual core (e.g. knowledge,
information, communication, representation) are neither owned by information
science nor likely to be assembled into an entirely credible canon without the
judicious...
Meaning and Purpose: Bridging the Gap from Mathematics to the Third Story: This project complements the Templeton project of Prof. Heylighen’s group on the origin of goal-directedness, which aims to develop a mathematical model based on Chemical Organization Theory for the origin of life, and the origin of goal-directed social systems. It proposes to make the link between this mathematical model and the philosophical idea of the Third Story as an alternative to traditional religious and scientific stories. This will require explaining the mechanisms of self-organization and emergence of autopoietic networks that form the basis of the model into a more intuitive narrative that would bridge the gap between mathematical demonstrations and a third story understandable by the broad public. The project would focus on the emergence of a common purpose in a group of individuals who are initially all pursuing their individual, selfish purposes, but who through interaction discover the...
In quantum field theory, the Casimir effect (or Casimir force)[1] is a physical force acting on the macroscopic boundaries of a confined space which arises from the quantum fluctuations of a field. The term Casimir pressure is sometimes used when it is described in units of force per unit area.[2][3] It is named after the Dutch physicist Hendrik Casimir, who predicted the effect for electromagnetic systems in 1948.

In the same year Casimir, together with Dirk Polder, described a similar effect experienced by a neutral atom in the vicinity of a macroscopic interface which is called the Casimir–Polder force.[4] Their result is a generalization of the London–van der Waals force and includes retardation due to the finite speed of light. The fundamental principles leading to the London–van der...
