Some Examples of Formation of Shells and Their Role in Establishment of Equilibrium

摘要

In this article we discuss the concept of equilibrium establishment in four most usual instances as is electrostriction and vaporization as related to the concept of equilibrium shell formation. Two more cases are then studied which are of relevance. One is the Brownian movement , the study of which is essential for pedagogical reasons as to exclusion of basic facts from statistics in a simple manner. The last one case studied is the very passage of current in a conductor. What is new in all these discussions is a simple but more detailed approach connecting the micro world to simple models of the macro world so that new comprehension be achieved. We will discuss matters in terms of order of magnitude of the quantities on what is to follow.
