"Basically, I found a very neat way to derive the standard wave equation in 1+1 dimensions. The only assumption I needed was that the speed of the wave is constant.

Wave kinetic equation for fibre lasers. Kinetic theory describes an average (macroscopic) probabilistic evolution of complex system. Starting from basic microscopic dynamic equations governing the ...

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...
