An exact science is any field of science capable of accurate quantitative expression or precise predictions and rigorous methods of testing hypotheses, especially reproducible experiments involving quantifiable predictions and measurements. Physics and Chemistry can be considered as exact sciences in this sense.
The term implies a dichotomy between these fields and others, such as the humanities.
