Physics
Physics is the branch of science concerned with the discovery and
characterization of universal laws which govern matter, energy, space, and time.
The role of physics, then, is to provide a logically ordered picture of nature
in agreement with experience.
Since antiquity, natural philosophers have sought to explain physical phenomena
such as the movement of the planets and the nature of matter, and this pursuit
was formerly the study known as "physics" (once spelled physike, in imitation of
Aristotle). The emergence of modern physics as a science distinct from natural
philosophy began with the scientific revolution of the 16th and 17th centuries
and continued through the dawn of modern physics in the early 20th century. The
field has continued to expand, with a growing body of research leading to
discoveries such as the Standard Model of fundamental particles and a detailed
history of the universe, along with revolutionary new technologies like nuclear
weapons and semiconductors. Research today progresses on a vast array of topics,
including high-temperature superconductivity, quantum computing, the search for
the Higgs boson, and the attempt to develop a theory of quantum gravity. Firmly
grounded in observations and experiments, with a rich set of theories expressed
in elegant mathematics, physics has made a multitude of contributions to
science, technology, and philosophy.
Discoveries in physics resonate throughout the natural sciences, and physics has
been described as the "fundamental science" because other fields such as
chemistry and biology investigate systems whose properties are based upon the
laws of physics.[1] Chemistry, for example, is the science of substances formed
by atoms and molecules in bulk, but the properties of chemical compounds are
determined by the physical properties of their underlying molecules. Accelerator

Research in physics is progressing constantly on a large number of fronts, and
is likely to do so for the foreseeable future .In condensed matter physics, the
greatest unsolved theoretical problem is the explanation for high-temperature
superconductivity. Strong efforts, largely experimental, are being put into
making workable spintronics and quantum computers. Learn Physics, SCHOOLS
