Systems science is an transdisciplinary[1] field that studies the nature of systems—from simple to complex—in nature, society, cognition, engineering, technology and science itself. To systems scientists, the world can be understood as a system of systems. The field aims to develop interdisciplinary foundations that are applicable in a variety of areas, such as psychology, biology, medicine, communication, business management, engineering, and social sciences.
Systems science covers formal sciences such as complex systems, cybernetics, dynamical systems theory, information theory, linguistics or systems theory. It has applications in the field of the natural and social sciences and engineering, such as control theory, operations research, social systems theory, systems biology, system dynamics, human factors, systems ecology, systems engineering and systems psychology. Themes commonly stressed in system science are (a) holistic view, (b) interaction between a system and its embedding environment, and (c) complex (often subtle) trajectories of dynamic behavior that sometimes are stable (and thus reinforcing), while at various 'boundary conditions' can become wildly unstable (and thus destructive). Concerns about Earth-scale biosphere/geosphere dynamics is an example of the nature of problems to which systems science seeks to contribute meaningful insights.

Systems art is art influenced by cybernetics, and systems theory, that reflects on natural systems, social systems and social signs of the art world itself.
Systems art emerged as part of the first wave of the conceptual art movement extended in the 1960s and 1970s. Closely related and overlapping terms are anti-form movement, cybernetic art, generative systems, process art, systems aesthetic, systemic art, systemic painting, and systems sculptures.

Selected biography -
Peter (Petre) Stoica (born 1949) is a researcher and educator in the field of signal processing and its applications to radar/sonar, communications and bio-medicine. He is a professor of Signals and Systems Modeling at Uppsala University in Sweden, and a Member of the Royal Swedish Academy of Engineering Sciences, the United States National Academy of Engineering (International Member), the Romanian Academy (Honorary Member), the European Academy of Sciences, and the Royal Society of Sciences. He is also a Fellow of IEEE, EURASIP, IETI, and the Royal Statistical Society.
He is known for his theoretical contributions to system identification and modeling, spectral analysis, array signal processing, space-time coding, and waveform design for active sensing. His practical contributions include the areas of wireless communications, microwave imaging for breast cancer detection, radar/sonar systems, acoustic source mapping, landmine and explosive detection, and magnetic resonance spectroscopy and imaging. His books on System Identification, Spectral Analysis, and Space-Time Coding for Wireless Communications have been used in both undergraduate and graduate courses and are highly cited (his works rank in the top 1% by citations for the field of engineering).
He has been included on the ISI list of the 250 most highly cited researchers in engineering in the world. (Full article...)Did you know
- ... that the American biologist Christopher Langton in the late 1980s is one of the founders of the field of artificial life.
- ... that self-organization is a process of attraction and repulsion in which the internal organization of a system, normally an open system, increases in complexity without being guided or managed by an outside source?
- ... that the Yugoslavian Mihajlo D. Mesarovic in 1970s wanted to provide a unified and formalized mathematical approach to all major systems concepts.
- ... that the anthropologist, linguist, and cyberneticist Gregory Bateson's most noted writings are Steps to an Ecology of Mind (1972) and Mind and Nature (1980).
