" Science is
a systematic discipline
that builds and organises
knowledge in the form of testable hypotheses and predictions about
the universe. Modern
science is typically divided into two or three
major branches: the natural
sciences (e.g., physics , chemistry ,
and biology ),
which study the physical
world ;
and the social
sciences (e.g., economics , psychology ,
and sociology ),
which study individuals and societies. Applied
sciences are
disciplines that use scientific knowledge for
practical purposes, such as engineering and
medicine. While
sometimes referred to as the formal
sciences ,
the study of logic , mathematics ,
and theoretical
computer science (which
study formal
systems governed
by axioms and
rules) are
typically regarded as separate because they rely
on deductive
reasoning instead
of the scientific
method or empirical
evidence as
their main methodology." Source
