Physics

"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.

Academic Departments

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.

Alternative

Non main-stream.

Astrophysics

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.

Please submit your site to the most appropriate category. Submitting to an incorrect category may delay review of your site.
Please submit only websites that have English language content to this category and its subcategories. If your site is in a language other than English, please submit it to the appropriate category of World.

Chats and Forums

This category is for sites for chatrooms and online discussion forums that are dedicated to physics in general.

Note that discussions dedicated to specific topics in Physics should go under the topical category in question.

This category is only for chat rooms and online discussion forums that are dedicated to Physics

Please submit only once, and only to this category if your site is dedicated to Physics in general. Thanks!

Classical Mechanics

Non-quantum and non-relativistic physics. Study of motion of "bodies" - physical objects. Concepts involved: force, velocity, acceleration, etc.

This category is specifically for sites on this formulation of classical mechanics.

Computational

This category lists sites pertaining to the use of computer simulations of physical systems and numerical methods for solving physics equations.

Sites should contain information on the use of computers to analyze physics research. Sites pertaining to education or demonstrations should be sent to Physics:Software, and site pertaining to computers without reference to physics should be sent to Computers

Condensed Matter

Condensed matter physics deals with the macroscopic and microscopic physical properties of matter. The most familiar examples of condensed phases are solids and liquids, which arise from the bonding and electromagnetic force between atoms.

Conferences

Physics Conferences Homepages providing Conference Announcements, Schedules, Application forms etc. This category also covers Physics meetings, workshops, summer schools and other events.

Conferences, meetings, workshops, summer schools and other events. Please do not submit the homepage of your institute, but the homepage of the Conference.

Crystallography

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.

Directories

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

Education

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.

Organizations

Organizations are groups of people working together towards a common goal. This category is for organizations that do not themselves conduct scientific research but aim to spread information about such research. They organize meetings, publish journals and provide research grants for scientists in the field.

There are separate categories for many of the different branches of science.
Please submit your site to the most appropriate category. Submitting to an incorrect category may delay review of your site.

Research Groups and Centers

Most research activities will either occur in academic departments or in research institutes (which may either be in universities or external). Both of these are included in this category.

Rheology

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.

Software

Sites should be focused on physics software which is either educational, used for demonstations, or tools of use in physics research. Sites related to computational physics or simulations of physical systems should be sent to Science/Physics/Computational/

Thermodynamics

Thermodynamics is the physics of energy, heat, work, entropy and the spontaneity of processes. It is closely related to statistical mechanics from which many thermodynamic relationships can be derived. Thermodynamics usually refers to equilibrium thermodynamics of quasistatic processes. Time-dependent thermodynamic processes are studied by non-equilibrium thermodynamics.

Please submit sites related to either classical thermodynamics. Please submit Statistical Mechanics sites in the appropriate category, not here.

Please submit only topical journals dealing with vacuum.

Weblogs

A weblog (often shortened just to blog) is a user-generated website where entries are made in journal style and displayed in reverse chronological order. This category is for blogs about breaking physics news or personal views on physics.
