The application of statistical and mathematical methods in the field of economics to test and quantify economic theories and the solutions to economic problems.

It is similar to the field of Physics in that one of the major goals is to search for a unified theory - the unification of the theoretical-quantitative and empirical-quantitative approach to economic problems.

In other words, the search for the application of mathematical models to one of the most complex subjects-- human behavior and social ills.

We will save the world not though God, but through Mathematics, as they are one and the same.
