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.

Energy, momentum and potential acoustical streaming in ideal medium
Mironov M.A.
Andreyev Acoustic Institute. Shvernik st., 4, Moscow, 117036, RussiaTwo interesting effects in the ideal medium are considered. The first one consists in the following. When body moves in an ideal medium, the medium has energy and momentum, defined through the attached mass and velocity of body. It turns out that the energy of the medium is concentrated around the body, while the momentum is placed at infinity. The second effect is concerned to acoustical streaming. The surface oscillations in an ideal medium can generate acoustical streaming - stationary flows of fluid.
