Abstract
It presents examples of aesthetic spectacles of nature involving physics and mathematics. It sets out the basic theory of waves in strings, wave equation and its Solutions, and its generalisation to two-dimensional case. It is discussed the case of flexible membranes and rigid plates. It explains how to get beautiful diagrams of nodal lines (Chladni figures) formed on oscillating
plates of various geometries and activated by various methods. In general, it works with materials for everyday use and easily accessible. It describes the experience of using the plates in teaching Physics and discusses how the motivation that awakens in students can be taken to impro ve achievements in this subject.
