Econophysics is a relatively new interdisciplinary field that combines principles of economics and physics to study financial systems. Synonyms for the term econophysics can include financial physics or quantitative finance, which both identify the application of mathematical and physical models to the study of financial markets. Other potential synonyms for econophysics include financial engineering, mathematical finance, or even financial astrophysics, which highlights the systems-level approach to examining markets similar to how astrophysicists look at celestial bodies. While the term econophysics may be the most commonly used descriptor, these synonyms all represent the same fundamental goal of exploring financial systems through mathematical models and quantitative analysis.
