In the framework of evolutionary physics, we must deal with goal functions instead of state functions: ecodynamic models must be based on relations evolving in time; far-from-equilibrium thermodynamics Prigogine is the foundation for a new description of nature. But if energy and mass are intrinsically conservative and entropy is intrinsically evolutionary, how can entropy be calculated on the basis of energy and mass quantities entropy paradox? This question is still unanswered and all we can do is note that the ecodynamic viewpoint is different from that of classical physics and classical ecology.
This paper is an attempt to deal with these concepts.
Indeed, the study of real-time systems, in other words systems in which temporal evolution plays a primary role, has made interesting advances. Specifically, the properties to describe in these systems are not only qualitative, properties which classical temporal logic can express, but also quantitative. Nature is evolutionary in character. The more one seeks to comprehend her, in the etymological sense of enclosing, imprisoning, in our mental schemes, the more she creates relations and complexity, memories and creative possibilities.

Ecological economists are inclined to acknowledge that much of what is important in human well-being is not analyzable from a strictly economic standpoint and suggests an interdisciplinary approach combining social and natural sciences as a means to address this. The potential for the substitution of man-made capital for natural capital is an important debate in ecological economics and the economics of sustainability. Models of Controlled Technological Renovation. Wikiquote has quotations related to: Ecological economics. Rather than try to show the huge range of ways that mathematics is assisting biologists in understanding the vast landscape of modern biology, I will take a look at a rather small domain, which offers ways to look at some traditional topics from a novel point of view. Ecological economics is distinguishable from neoclassical economics primarily by its assertion that the economy is embedded within an environmental system.

The problems of interrelation between human economics and natural environment include scientific, technical, economic, demographic, social, political and.

A system model of two-sector economics in which energy and production sectors act separately is described.
Production is divided into two sectors — the first sector makes the final product, and the second sector — produces energy required for a final product. The models for the production sectors are written down. The system model as a system of differential equation is obtained.
Based on the distribution of productive capacity according to the technologies, the parametric representation of ecological and economical production function is shown. Skip to main content.
