Abstract

In the quest to formulate useful mathematical models of aspects of the world, it turns out on surprisingly many occasions that the model becomes clearer, more compact, or more tractable if one introduces some form of variational principle. This means that one can find a quantity, such as energy or entropy, which obeys a minimization, maximization or saddle-point law.
