Science Newsletter of the Faculty fo Physics
This is a new bulletin, which, as we hope, will bring fresh, updated information on scientific news, research activities, and related events in the life of our department to our staff members, undegraduate and graduate students, postdocs, collaborators and partners. We greatly hope that this Science Newsletter will help us to find new partners in research and shorten the way from fundamental research to applications and innovations, from our fundamental discoveries to their successful implementations in not too distant future.
XIV National School-Seminar "Wave phenomena in inhomogeneous media"
The conference papers from the School-Seminar «Waves-2014» will be submitted for publishing in the Memoirs of the Faculty of Physics journal.

Strongly nonlinear phenomena in acoustics
O.V. Rudenko
Department of Acoustics, Faculty of Physics, M.V.Lomonosov Moscow State University. Moscow 119991, Russia.The difference between strongly nonlinear waves and waves with strongly displayed weak nonlinearity is pointed out. The classification of strongly nonlinear systems is given. The simplest structural features of meta-materials having high nonlinearity are described. Examples of mathematical models having sufficient generality and interesting for nonlinear wave physics are given. Particle-like properties of singular solutions, as well as some unusual phenomena are pointed out. Accretion, self-trapping and self-splitting can exemplify such phenomena.
