Tiny village is latest victim of the 'The hum' Vortex Shedding in a Cylinder Wake. Soliton. In mathematics and physics, a soliton is a self-reinforcing solitary wave (a wave packet or pulse) that maintains its shape while it travels at constant speed.
Solitons are caused by a cancellation of nonlinear and dispersive effects in the medium. (The term "dispersive effects" refers to a property of certain systems where the speed of the waves vary according to frequency.) Solitons arise as the solutions of a widespread class of weakly nonlinear dispersive partial differential equations describing physical systems. Definition[edit] A single, consensus definition of a soliton is difficult to find.
