Physics (from Ancient Greek: φυσική (ἠπιστήμη),
romanized: physikḗ (epistḗmÄ"), lit. 'knowledge of nature', from
Ï†Ï ÏƒÎ¹Ï‚ phýsis 'nature') is the natural science that studies
matter,[a] its motion and behavior through space and time, and the
related entities of energy and force. Physics is one of the most
fundamental scientific disciplines, and its main goal is to understand
how the universe behaves.[b]Physics is one of the oldest academic
disciplines and, through its inclusion of astronomy, perhaps the
oldest. Over much of the past two millennia, physics, chemistry,
biology, and certain branches of mathematics were a part of natural
philosophy, but during the Scientific Revolution in the 17th century
these natural sciences emerged as unique research endeavors in their
own right.[c] Physics intersects with many interdisciplinary areas of
research, such as biophysics and quantum chemistry, and the boundaries
of physics are not rigidly defined. New ideas in physics often explain
the fundamental mechanisms studied by other sciences and suggest new
avenues of research in academic disciplines such as mathematics and
philosophy. Physics Top Movies & Young Movies
