Saturn's largest moon most likely uninhabitable

A study led by Western astrobiologist Catherine Neish shows the subsurface ocean of Titan—the largest moon of Saturn—is most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead ...

New chip opens door to AI computing at light speed

University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing ...

A physical qubit with built-in error correction

There has been significant progress in the field of quantum computing. Big global players, such as Google and IBM, are already offering cloud-based quantum computing services. However, quantum computers cannot yet help with ...

Andean farmers use age-old technique amid climate change

From the sky, they look like huge, circular patterns made by aliens—but in fact, they are an age-old technique farmers have brought back to fight the climate crisis on the Andean plateaus of Puno.

Astrophysical jet caught in a 'speed trap'

The science fiction author Arthur C. Clarke selected his own seven wonders of the world in a BBC television series in 1997. The only astronomical object he included was SS 433. It had attracted attention already in the late ...

System

System (from Latin systēma, in turn from Greek σύστημα systēma) is a set of interacting or interdependent entities forming an integrated whole.

The concept of an 'integrated whole' can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the set and elements not a part of the relational regime.

The scientific research field which is engaged in the study of the general properties of systems include systems theory, systems science, systemics and systems engineering. They investigate the abstract properties of the matter and organization, searching concepts and principles which are independent of the specific domain, substance, type, or temporal scales of existence.

Most systems share common characteristics, including:

The term system may also refer to a set of rules that governs behavior or structure.
