This note presents an expression of radiated sound pressure from a con"ned source in terms of the spherical harmonic functions. In the expression, the spherical harmonic functions are interpreted as the radiating modes and their superposition results in various radiation patterns. The orthonormal pr
Rapidly moving sources create pairs in the vacuum and lose energy. In consequence of this, the velocity of charged bodies in their center-of-mass frame cannot approach the speed of light closer than a certain limit which depends only on the coupling constant. The vacuum back-reaction secures the obs
