Nonlinear pattern formation occurs throughout nature, in everything from sand ripples on a beach, snowflakes, the population ecology of lemmings, and much, much more. Faraday waves are an archetypical nonlinear pattern formation system for laboratory study, and the same experimental system can be used to observe oscillons, a soliton-like localized excitation. This experiment is inspired by research carried out by Prof. Stephen Morris's Experimental Nonlinear Physics Group.
