Abstract

In order to use the framework of general system theory (GST) to unify the three mechanics subjects of classical mechanics, quantum mechanics, and relativistic mechanics, a new general system theory (NGST) is developed based on a new ontology of ether and minds as the fundamental existences in the world. Based on this new ontology, many fundamental concepts have been detected to be ambiguously defined nowadays and particularly lack of ontological support. In our previous work, some of the fundamental concepts such as universe, world, time, space, matter, ether, mind, life, field, force have been redefined. The purpose of this paper is to clarify the concepts of energy, heat, work, entropy, and information in our NGST. This is an important and necessary step in the development of the NGST.
