Belief of religious thought, "belief-that" instead belonged to epistemological considerations. To "believe in" someone or something is a distinct concept from "believing-that." There are at least these types of belief-in: Economic beliefs are beliefs which are reasonably and necessarily contrary to the tenet of rational choice or instrumental rationality. Studies of the Austrian tradition of the economic thought, in the context of analysis of the influence and subsequent degree of change resulting from existing economic knowledge and belief, has contributed the most to the subsequent holistic collective analysis. Insofar as the truth of belief is expressed in sentential and propositional form
Principle of least action starting point is the "action", denoted formula_1 (calligraphic S), of a physical system. It is defined as the integral of the Lagrangian "L" between two instants of time "t" and "t" - technically a functional of the "N" generalized coordinates q = ("q", "q", ... , "q") which define the configuration of the system: where the dot denotes the time derivative, and "t" is time. Mathematically the principle is where "δ" (lowercase Greek delta) means a "small" change. In words this reads: In applications the statement and definition of action are taken together: The action and Lagrangian both contain the
