  2. Theoretical physics - Wikipedia

    en.wikipedia.org/wiki/Theoretical_physics

    Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics , which uses experimental tools to probe these phenomena.

  3. Systems theory - Wikipedia

    en.wikipedia.org/wiki/Systems_theory

    Systems theory is manifest in the work of practitioners in many disciplines, for example the works of physician Alexander Bogdanov, biologist Ludwig von Bertalanffy, linguist Béla H. Bánáthy, and sociologist Talcott Parsons; in the study of ecological systems by Howard T. Odum, Eugene Odum; in Fritjof Capra's study of organizational theory; in the study of management by Peter Senge; in ...

  4. List of types of systems theory - Wikipedia

    en.wikipedia.org/.../List_of_types_of_systems_theory

    This list of types of systems theory gives an overview of different types of systems theory, which are mentioned in scientific book titles or articles. [1] The following more than 40 types of systems theory are all explicitly named systems theory and represent a unique conceptual framework in a specific field of science .

  5. Systems science - Wikipedia

    en.wikipedia.org/wiki/Systems_science

    Systems science, also referred to as systems research or simply systems, [1] is a transdisciplinary [2] field that is concerned with understanding simple and complex systems in nature and society, which leads to the advancements of formal, natural, social, and applied attributions throughout engineering, technology and science, itself.

  6. Theory - Wikipedia

    en.wikipedia.org/wiki/Theory

    The English word theory derives from a technical term in philosophy in Ancient Greek.As an everyday word, theoria, θεωρία, meant "looking at, viewing, beholding", but in more technical contexts it came to refer to contemplative or speculative understandings of natural things, such as those of natural philosophers, as opposed to more practical ways of knowing things, like that of skilled ...

  7. Applied mechanics - Wikipedia

    en.wikipedia.org/wiki/Applied_mechanics

    Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. [1] In short, when mechanics concepts surpass being theoretical and are applied and executed, general mechanics becomes applied mechanics.

  8. Theoretical computer science - Wikipedia

    en.wikipedia.org/wiki/Theoretical_computer_science

    Information theory is a branch of applied mathematics, electrical engineering, and computer science involving the quantification of information. Information theory was developed by Claude E. Shannon to find fundamental limits on signal processing operations such as compressing data and on reliably storing and communicating data.

  9. Dynamical systems theory - Wikipedia

    en.wikipedia.org/wiki/Dynamical_systems_theory

    Dynamical systems theory and chaos theory deal with the long-term qualitative behavior of dynamical systems.Here, the focus is not on finding precise solutions to the equations defining the dynamical system (which is often hopeless), but rather to answer questions like "Will the system settle down to a steady state in the long term, and if so, what are the possible steady states?", or "Does ...
