Units and Dimensions - RIT
... Units and Dimensions In physics we measure quantities such the length of a room or the mass of an electron. The measurement results in a “physical quantity” consisting of a pure number and a unit. Physicists also discuss dimensions of physical quantities. The System International (SI) is based on 4 ...

hydrodynamics of a rotating strongly interacting fermi gas
... Strongly interacting Fermi gases are unique quantum fluids that can be used to model other strongly interacting systems in nature, such as the quark-gluon plasma of the big bang, high temperature superconductors, and nuclear matter. This is made possible through the use of a collisional resonance, p ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
