through space time and all that derives from these, such as energy and
force. Physics is the general analysis of nature, conducted in order
to understand how the world and universe behave.
Physics is the science of matter and energy and of interactions
between the two, grouped in traditional fields such as acoustics,
optics, mechanics, thermodynamics, and electromagnetism. Modern
extensions also include atomic and nuclear physics, cryogenics, solid-
state physics, particle physics, and plasma physics.
Physics covers a wide range of phenomena, from the smallest sub-atomic
particles, to the largest galaxies. The most basic parts of physics
are mechanics and field theory. Mechanics is concerned with the motion
of particles or bodies under the action of given forces. The physics
of fields is concerned with the origin, nature, and properties of
gravitational, electromagnetic, nuclear, and other force fields.
Physics uses the scientific method to test the validity of a physical
theory, using a methodical approach to compare the implications of the
theory in question with the associated conclusions drawn from
experiments and observations conducted to test it.
Contemporary research in physics can be broadly divided into condensed
matter physics; atomic, molecular, and optical physics; particle
physics; astrophysics; geophysics and biophysics.
Condensed matter physics is the field of physics that deals with the
macroscopic physical properties of matter. Atomic, molecular, and
optical physics (AMO) is the study of matter-matter and light-matter
interactions on the scale of single atoms or structures containing a
few atoms. Particle physics is the study of the elementary
constituents of matter and energy, and the interactions between them.
It may also be called "high energy physics", because many elementary
particles do not occur naturally, but are created only during high
energy collisions of other particles, as can be detected in particle
accelerators. Astrophysics and astronomy are the application of the
theories and methods of physics to the study of stellar structure,
stellar evolution, the origin of the solar system, and related
problems of cosmology. Applied physics is a general term for physics
research which is intended for a particular use. An applied physics
curriculum usually contains a few classes in an applied discipline,
like geology or electrical engineering.
Physics is used heavily in engineering. For example, Statics , a
subfield of mechanics, is used in the building of bridges and other
structures.
Research in physics is continually progressing on a large number of
fronts. In condensed matter physics, an important unsolved theoretical
problem is that of high-temperature superconductivity. Many condensed
matter experiments are aiming to fabricate workable spintronics and
quantum computers. In particle physics, the first pieces of
experimental evidence for physics beyond the Standard Model have begun
to appear.
