Physics print that page


Physics is one of the oldest academic disciplines , perhaps the oldest through its inclusion of astronomy . [ 6 ] Over the last two millennia, physics was a part of natural philosophy along with chemistry , certain branches of mathematics , and biology , but during the Scientific Revolution

Spin (physics) print that page

In quantum mechanics and particle physics , spin is a fundamental characteristic property of elementary particles , composite particles ( hadrons ), and atomic nuclei . [ note 1 ] All elementary particles of a given kind have the same spin quantum number , an important part of a particle | 2011/10/3 1:15:00

Computational physics print that page


Computation now represents an essential component of modern research in accelerator physics , astrophysics , fluid mechanics , lattice field theory / lattice gauge theory (especially lattice quantum chromodynamics ), plasma physics (see plasma modeling ), solid state physics and soft

Atomic physics print that page

The term atomic physics is often associated with nuclear power and nuclear bombs , due to the synonymous use of atomic and nuclear in standard English . However, physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons | 2011/4/28 9:36:42

Moscow Institute of Physics and Technology print that page


Kapitsa argued for the need for such a school, which he tentatively called the Moscow Institute of Physics and Technology , to better maintain and develop the country's defense potential. The institute would follow the principles outlined above, and was supposed to be governed by a board of

Digital physics print that page

In physics and cosmology , digital physics is a collection of theoretical perspectives based on the premise that the universe is, at heart, describable by information , and is therefore computable . Therefore, the universe can be conceived as either the output of a computer program or | 2011/4/25 1:16:44

Parity (physics) print that page

In physics , a parity transformation (also called parity inversion ) is the flip in the sign of one spatial coordinate . In three dimensions, it is also commonly described by the simultaneous flip in the sign of all three spatial coordinates: A 3×3 matrix representation of P would | 2011/8/6 8:25:32

Causality (physics) print that page

equal probability of stopping at each position. [ edit ] Various concepts of cause and effect in physics In physics it is useful to interpret certain terms of a physical theory as causes and other terms as effects. Thus, in classical (Newtonian) mechanics a cause may be represented by | 2011/8/9 3:03:46

Plasma (physics) print that page


In physics and chemistry , plasma is a state of matter similar to gas in which a certain portion of the particles are ionized . Heating a gas may ionize (reduce the number of electrons in) its molecules or atoms, thus turning it into a plasma, which contains charged particles: positive

Particle physics print that page


Modern particle physics research is focused on subatomic particles , including atomic constituents such as electrons , protons , and neutrons (protons and neutrons are actually composite particles called baryons , made of quarks ), particles produced by radioactive and scattering processes
