This book highlights a broad range of modern information technology tools, techniques, investigations and open challenges, mainly with applications in systems research and computational physics. Divided into three major sections, it begins by presenting specialized calculation methods in the framework of data analysis and intelligent computing. In turn, the second section focuses on application aspects, mainly for systems research, while the final section investigates how various tasks in the basic disciplines-mathematics and physics-can be tackled with the aid of contemporary IT methods. The book gathers selected presentations from the 3rd Conference on Information Technology, Systems Research and Computational Physics (ITSRCP'18), which took place on 2-5 July 2018 in Krakow, Poland. The intended readership includes interdisciplinary scientists and practitioners pursuing research at the interfaces of information technology, systems research, and computational physics.

This book illustrates the applicability of the seminal and controversial metaphor of the "invisible hand" in modern sociological theory. It shows that sociologists have long been part of a field mainly associated with economists and political philosophers. Though unlike the framing that builds directly on Adam Smith, sociological theory focuses on undesirable and perverse outcomes. Furthermore, the sociological angle favors the explanation of invisible hand-like mechanisms as contingent upon social structures and broader processes. Thus, it goes beyond its classical formulation in terms of interdependence, interaction and aggregation of individual actions. This book gathers contributions of remarkable authors who are linked directly either with the invisible hand metaphor, with the spontaneous order phenomenon or with the unintended consequences issue and aims to describe the traditional and contemporary applicability of the sociological framing of the invisible hand for social sciences.
