astrophysics
a branch of astronomy concerned with the study of the physical and chemical properties of material objects and energy sources situated outside the boundaries of the earth's atmosphere
atomic and molecular physics
the study of the properties of matter at the atomic or molecular scale; the study of the structure of atoms and molecules and the forces that act between positive nuclei and the negative electrons in orbits around nuclei or the interaction of electrons from one atom with those form another.
biophysics
this branch studies the physics of living organisms; it is sometimes considered to be an overlap of biology and physics; biophysics and medicine go hand in hand, as this study plays a big part in the development of life-saving machines and artificial limbs; it also has broader uses in engineering; everything from cars to sneakers is influenced by our understanding of biophysics
classic electrodynamics
this field is most broadly applied of all the branches of physics; classical electrodynamics is based on Maxwell's laws of electromagnetism, which describes all kinds of electromagnetic phenomena from atomic to global scales; it is the theoretical basis of optics, telecommunication and many other sub-fields; its domain extends over all of nature, as the 'Electromagnetic Force' is all pervading, and we live in an electromagnetic world
condensed matter physics
a sub-branch of quantum physics and statistical mechanics, which describes all phenomena that occur in matter, which is in condensed form; this includes everything from liquids, solid and gases; the physics of semiconductor devices, which make today's age of information technology possible, is a result of research developments in condensed matter physics; it describes all phenomena in bulk matter like ferromagnetism, super fluidity and superconductivity
chemical physics
this is the branch of physics involves using the principles and theories of physics to study chemical processes; it is very similar to physical chemistry and has significant overlap with it; the development of batteries, fuels, medicines and building materials all result from the work people do in chemical physics
cosmology
a branch of astronomy focused on the study of the origin, structure, and evolution in space and time of the physical universe
dynamics
a chapter of mechanics dealing with the behavior of material objects under the action of external forces
electricity
the study of the behavior of electrical charges and the fields they create in their surrounding space
electrodynamics
the study of the relations between electrical, magnetic, and mechanical phenomena; the study of the interactions between electric currents and magnetic fields created by other electric currents
field theory
a classical or quantum mechanical theoretical study of fields, based on the knowledge of the field equations, or of the commutation rules satisfied by the field operators
fluid mechanics
the study of the properties and behavior of matter in fluid (gas or liquid) state
geophysics
the physics of the earth and its environment, including the physics of fields such as meteorology, oceanography, and seismology
hydrostatics/hydronamics
the study of the mechanical behavior of fluids and of solid bodies immersed in fluids, which are in static equilibrium or in motion relative to them
magnetism
the study of magnetic properties of matter and the fields created in the surrounding space
mechanics
the study of the behavior of physical systems in terms of their position in space, under the action of external forces which may be equal or different from zero
mathematical physics
this is the branch of physics, which gives theoretical physics its tools of analysis; mathematics is the language of nature and therefore if one wants to understand nature, one must understand mathematics; mathematics brings precision to physics; it is the branch which is an overlap of pure mathematics and physics; mathematical physics techniques form the toolbox of a physicist; just like a workman must use the right kind of tools to get his job done, so must a physicist use the right mathematical tools to solve a problem; the more and more deeply we explore nature, every new law discovered can only be expressed in a new form of mathematics
molecular physics
not to be confused with Atomic Physics, molecular physics deals with entire molecules and the atoms that form them; by learning how to manipulate the elements, we can create new types of substances, ranging from durable metals to plastics and gels, that get used in many different industries
nuclear physics
the study of the properties of atomic nuclei; the study of the structure of atomic nuclei and the forces responsible for the stability or the disintegration of atomic nuclei
non-linear physics
this is a sub-field of classical mechanics, which solves the problems on macroscopic scales, which cannot be solved by classical mechanics; it is an advanced branch of mathematics, which attempts to solve non-linear differential equations of motion, which are not amenable to a solution by conventional techniques; a greater part of it is also known as 'Chaos Theory', which delves in to the organized chaos that exists in the macroscopic world; it is the most happening branch of physics currently
optical physics
this is the branch of physics concerned with the properties and behavior of light; it has applications in mechanics and computer engineering, as well as the use of lasers
optics
the study of light and vision; the study of the phenomena associated with generation, transmission and detection of electromagnetic radiation, from the short wave length edge of radio waves (1 mm) to the long wave length edge of X-ray (1 nm); the study of waves associated with particles, i.e. electron optics, neutron optics, etc.
particle physics
the study of the structure, properties and interactions of elementary particles
planetary physics
the study of the origin, structure, and evolution of planets and planetary systems
plasma physics
the study of the structure and properties of materials in plasma phase
quantum electrodynamics
a quantum theory of electromagnetic radiation; a quantum theory of the interaction of radiation with electrically charged particles, in particular with atoms and their constituent electrons
quantum mechanics
a theory of matter based on the idea that material particles may be described as waves, and waves may be described as particles
solid state physics
the study of the structure and properties of materials in solid phase
space physics
the study of planetary and interplanetary magnetized plasmas; the study of the energy flow from the sun through the solar wind and into terrestrial and planetary magnetospheres, both induced and intrinsic, and how this energy is dissipated within these magnetospheres
statics
a chapter of mechanics dealing with the equilibrium of external forces acting on material objects
statistical mechanics
the branch of physics that makes theoretical predictions about the behavior of macroscopic systems on the basis of statistical laws governing its component particles
surface physics
the study of the structure of solid surfaces; the study of physical and chemical processes occurring at the interface between solid objects and the gas or liquid environments surrounding them
thermodynamics
this is the branch of physics that studies heat and its relationship with other forms of energy; like molecular physics, there are thousands of applications for this research, ranging from manufacturing to new forms of energy
atmospheric physics
meteorology, study of tornadoes and hurricanes
Nuclear and High Energy Physics (HEP)
the structure and particles of matter, nature of the nuclei of atoms, more efficient nuclear fuel arrays for power, develop fusion as a widely available, economical energy source
applied physics
develops new and practical technologies, works with mechanical, electrical, and civil engineers
