"The Principle of Least Action originates in the idea that, if Nature has a purpose, it should follow a minimum or critical path. This simple principle (and its variants and generalizations) applies to optics, mechanics, electromagnetism, relativity and quantum mechanics, and pr…

This text brings history and the key fields of physics together to present a unique technical discussion of the principles of least action.
This book presents tutorial overviews for many applications of variational methods to molecular modeling. Topics discussed include the Gibbs-Bogoliubov-Feynman variational principle, square-gradient models, classical density functional theories, self-consistent-field theories, p…
