Nonlinear waves and shocks in relativistic two-fluid hydrodynamics
... Nonlinear waves were extensively studied in the framework of magnetohydrodynamics (MHD) and two-fluid hydrodynamics. A typical analysis sequence is as follows: onedimensionality assumption, model equation construction, and stationary solution analysis with particular attention to solitons. Although ...

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.
