What physical effects are involved?, Ian Stewart asks this question and gives the answer that “equations are the lifeblood of mathematics, science and technology”, and adds that “… they reveal deep and beautiful patterns and regularities”.

What physical mechanisms govern waves in non-conservative systems?,equationis also conservative and admits infinitely many conserved quantities : . These equations express the conservation of mass, momentum, and energy, respectively. The accuracy of a numerical method can be checked by calculating these conserved quantities at every time step.

What is wave motion?,As surprising as it may sound, there is no simple answer to this question. Better not ask what a waveis, but ask what can be said about a wave, explains J. Pierce . The confusion is caused by the wavemotion itself, which can be related to propagating disturbances or oscillations. Nevertheless, let us first present some definitions.

Book 2015low the analytical sequence from elementary understandings to complicated cases, following a step-by-step path towards increased knowledge. The focus is on waves in elastic solids, although some examples also concern non-conservative cases for the sake of completeness. Special attention is paid to t
