The exact sciences, sometimes called the exact mathematical sciences,
are those sciences "which admit of absolute precision in their results"; especially the
mathematical sciences. Examples of the exact sciences are mathematics,
optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultra ...

astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest ...
, and
physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which rel ...

Leibniz, and
Kant to the
logical positivists took as paradigms of rational and
objective knowledge. These sciences have been practiced in many cultures from antiquity to modern times. Given their ties to mathematics, the exact sciences are characterized by accurate

measurements.
The distinction between the quantitative exact sciences and those sciences that deal with the causes of things is due to
Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical Greece, Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatet ...

natural philosophy
Natural philosophy or philosophy of nature (from Latin ''philosophia naturalis'') is the philosophical study of physics, that is, nature and the physical universe. It was dominant before the development of modern science.
From the ancient wor ...
and considered the exact sciences to be the "more natural of the branches of mathematics."
Thomas Aquinas
Thomas Aquinas, OP (; it, Tommaso d'Aquino, lit=Thomas of Aquino; 1225 – 7 March 1274) was an Italian Dominican friar and priest who was an influential philosopher, theologian and jurist in the tradition of scholasticism; he is known wi ...
employed this distinction when he pointed out that astronomy explains the
spherical shape of the Earth by mathematical reasoning while physics explains it by
material causes. This distinction was widely, but not universally, accepted until the
scientific revolution
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed ...
of the 17th century.
Edward Grant has proposed that a fundamental change leading to the new sciences was the unification of the exact sciences and physics by
Kepler,
Newton, and others, which resulted in a quantitative investigation of the physical causes of natural phenomena.
Linguistics
Linguistics is the scientific study of human language. It is called a scientific study because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language, particularly its nature and structure. Lingu ...
and
comparative philology have also been considered exact sciences, most notably by
Benjamin Whorf.
