Finance is a quantitative discipline.
Both theoretical and empirical finance rely heavily on the skills and knowledge that are second nature to many majors which rely heavily on mathematics and statistics. For example, the famous Black and Scholes option pricing model in finance is the solution to a partial differential equation which is the heat exchange equation from physics. Other theories and techniques from mathematics and physics such as chaos theory and stochastic processes are used to develop financial models. Thus the finance discipline is becoming increasingly complex and dependent on the skills physics, mathematics, statistics, and other mathematically oriented majors possess.
