Speed of light, speed at which light waves propagate through different materials. In a vacuum, the speed of light is 299,792,458 meters per second. The speed of light is considered a fundamental constant of nature. Its significance is far broader than it
An all speed scheme for the Isentropic Euler equations is presented in this paper. When the Mach number tends to zero, the compressible Euler equations converge to their incompressible counterpart, in which the density becomes a constant. Increasing approximation errors and severe stability constraints...
Mass-Speed EquationSubstance RedistributionBasic Particle Model (BPM)This work provides that, when an object is accelerated, the substance quantity included in the object should remain a constant with that substance being redistributed within the object. For the same object, a different mass ...

Nature tries to minimize the expected value for the action, in which the particle’s velocity is consider to be a control parameter of the optimization. The principles formulated above are not new in this paper. However, attributing them to a single author would not be correct, as they have...
The sound speed decreases from the surface down to h = 1200 m and then increases from h = 1200 m to the bottom of the ocean (h = 4800 m). Figures which present the ray pattern for horizontal distances up to 150 km and for frequencies between 25 and 200 Hz clearly point out the ...
