The chapter discusses two examples of approximations in the modeling of phenomena.
Cornell has long been a leader in theoretical astrophysics the modeling of phenomena in our solar system, galaxy, distant galaxies and the early universe.
Like the physical and biological sciences, which consist of bodies of knowledge and formal models of phenomena spanning many application disciplines, the information sciences involve thought paradigms, tools, and techniques with broad applicability.
This is due to their role as solutions of fractional order differential and integral equations, as the better mathematical models of phenomena of various physical, engineering, automatization, chemical, biological, Earth science, economics etc. nature.
Depending on the nature of the target, such models are either models of phenomena or models of data.

The main references on fractional calculus also point out the power and usefulness of this topic to the modeling of phenomena in a wide range of scientific fields.
Integer-order impulsive differential equations have become important in recent years as mathematical models of phenomena in both physical and social sciences.
On the other hand, impulsive differential equations have become important in recent years as mathematical models of phenomena in both the physical and the social sciences.
Modeling of phenomena based on conventional mathematical tools (e.g., differential equations) is not appropriate for dealing with ill-defined and uncertain problems.
