Physics
is the study of energy and its interaction
with matter. Because of the primacy of
energy in terms of the history of the
universe, because all matter must interact
with energy to express its properties
and engage in transformations, and because
energy is the key player when matter is
decomposed into its most basic parts,
physics is often considered to be the
fundamental science.
