2005-10-25 · Linear Variation Theory: Building a Better Wavefunction Piece by Piece Linear combinations of functions are a good way to build wavefunctions. The goal is to have "off the shelf" sets of functions that we can use to build wavefunctions for molecules. The objectives of Physical Chemistry: Concepts and Theory are presented. The book is organized in accordance with the mathematics used: continuum for thermodynamics; discrete for quantum theory; statistics and probabilities for statistical mechanics; and the mathematics for potential-driven changes at short and long times for kinetics.

### The Variational Method is a mathematical method that is used to approximately calculate the energy levels of difficult quantum systems. It can also be used to approximate the energies of a solvable system and then obtain the accuracy of the method by comparing the known and approximated energies.

In science and especially in mathematical studies, a variational principle is one that enables a problem to be solved using calculus of variations, which concerns finding such functions which optimize the values of quantities that depend upon those functions. For example, the problem of determining the shape of a hanging chain suspended at both ends—a catenary—can be solved using variational calculus, and in this case, the variational principle is the following: The solution
Variation Theory purely in theoretical terms, but rather attempts to explain Variation Theory through the use of actual classroom examples, which are carefully chosen to illustrate how different elements of the theory can be applied. All learning theories aim to explain learning, and all useful learning theories
Variation theory offers a theoretical framework from which to explore possible variations in experience and the resulting differences in learning and understanding.

Deming added to Shewhart's work by connecting the concept of a process. Thus, when key measures of process outcomes fall in a random pattern one learns that the variation is the result of common causes of variation from within the process. Variation Theory allows us, as teachers, to examine the learning event and the object of learning from the perspectives of both the teacher and the students in order to understand not only what This website is my attempt to assemble a collection of high-quality, sequences of questions and examples using key principles from Variation Theory. By holding key features between questions and examples constant, together with the mathematical behaviour that I call reflect, expect, check, explain and the supporting role of the teacher, I believe we can help students better understand key mathematical ideas.
