Physics (originates from Greek word physis means "nature") is a part of natural philosophy and a natural science that
involves the study of matter and its motion through
space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature,
conducted in order to understand how the universe behaves.
Physics is one of the oldest academics disciplines , perhaps
the oldest through its inclusion of astronomy. Over the last
two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 17th century, the natural sciences emerged
as unique research programs in their own right. 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 of other sciences,
while opening new avenues of research in areas such as mathematics and
philosophy.
Physics also makes significant contributions through advances in
new technologies that arise from theoretical
breakthroughs. For example, advances in the understanding of electromagnetism or Nuclear Physics led
directly to the development of new products which have dramatically transformed
modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the
development of ; industrialization and advances in mechanics inspired the development of calculus.
