Max Bourne's works on the dynamics of crystal lattices played an important role in the construction of the theory of a solid body and are now considered classical. These studies were started together with Theodor von Karman under the influence of one of Einstein's early articles (1907), in which an attempt was made to describe the specific heat of crystals using Planck's quantum considerations. Bourne and Carman set out to explain the properties of solids, based on the idea of their structure. The first joint work (1912) contains the main ideas of crystal lattice dynamics: identification of independent degrees of freedom of the crystal with normal modes of oscillations of the whole body (Planck's formula was applied to normal modes); periodic boundary conditions (born — Karman conditions) to eliminate surface effects; analysis based on three-dimensional Fourier transform and representation of acoustic and optical branches of the vibrational spectrum. They also demonstrated the transition to a continuous medium model in the long-wave limit.]]> 2018-12-23 19:03:34 UTC https://padlet.com/ds_dota_fk/ux5vump6brqz/wish/316569720
