"Physics is the study and application of the fundamental laws of nature, including the laws of motion, gravity, electromagnetism, heat, and microscopic interactions. These laws govern the behavior of objects at all scales, from the smallest subatomic particles to the entire observable universe. In between, physicists study nuclear reactions, the interactions of atoms with light, properties of solids, chaotic dynamics of fluids, and the evolution of stars and galaxies, among many other applications."

If this doesn't tickle your fancy, there is always the quote from Rutherford: "In science, there is only physics; all the rest is stamp collecting."

This category includes sites about the basic laws of nature, such as the laws of motion, electromagnetism and atomic interactions.

Webpages that focus more on mathematics as it applies to physics should be placed in the Mathematical Physics subcategory.

Webpages that focus on the interdisciplinary topic of combining physics, chemistry, thermodynamics and quantum mechanics should be placed in Physical Chemistry

Submit sites about the study of the nature of space and astral bodies in Astrophysics. But, webpages that offer general statistics and data about the universe should be submitted to Astronomy.
Submissions should contain general information on physics programs and departments at actual universities. Sites related to specific people should be redirected to Physics:Physicists. Sites on specific topics should be sent to the appropriate topic category.
Non main-stream.
Astrophysics is the branch of astronomy that deals with the physics of the universe, including the physical properties (luminosity, density, temperature, and chemical composition) of celestial objects and the interstellar medium, as well as their interactions.

The Crystallography is a misleading term. Diamonds and relatives are on the peripheries of the crystallographer field of interest. Probably the better name would be the "structural chemistry" or even the "structural biology". How the basic structures of living, rapidly changing world are connected with something as static as crystals? If one want to know 3-D structures of biological molecules - one need to crystalize them, then to put them into the X-ray beam and to interpret the obtained diffraction pattern. For simplicity alternative techniques of structural biology, for example NMR, neutron and electron crystallography are also included here.

A place for sites which have gathered together many links related to physics, usually in a useful or unique way.

Science/Physics/Education is for EDUCATIONAL web sites of interest to educators, parents, students and professionals emphasizing the teaching or learning of various aspects of physics or physical science. The best sites will try to teach or instruct about physics or physical science, though clear, easy-to-follow explanations of topics are useful as well. There are both a Science/Chemistry/Education and a Science/Biology/Education category here at ODP, and they may be more appropriate for some site submissions. This category is not for software or selling of products.

    Rheology is science of flow, of deformation of liquids and solids, and of the in-between viscoelastic materials, such as asphalt, glass, dough or plastics (polymers). The properties of the materials are described by the constitutive equation (rheological equation of state) which may an include other then mechanical quantities, such as magnetic or electrical fields. Constitutive equation describes the memory of materials, effects of thermal and stress history and effects such as hysteresis.
    Rheology is an interdisciplinary field which draws on mathematics and differential geometry, chemistry, thermodynamics, polymer science and mechanics of continua. It includes as special cases hydrodynamics and theory of elasticity while studying more general cases of viscoelastic materials and of non-linear and complex fluids.

    Derivation of the constitutive equation from the microscopic properties, the structure-property relationship of materials or ''structural rheology'' generalises methods of statistical mechanics from study of N-particle systems to more complex ensembles, e.g. to three-dimensional networks of polymer chains to derive equations of rubber elasticity.
