BigBang Theory (essay) A cosmological model to explain the origins of matter,energy, space, and time, the Big Bang theory asserts that the universe began ata certain point in the distant past-current estimates put it at roughly 13.7 billionyears ago-expanding from a primordial state of tremendous heat and density. Theterm is also used more generally to describe the vast explosion that erupted atthe beginning of space and time, bring...
Nonlinear multi-wave coupling and resonance inelastic structures Kovriguine DA Solutions to the evolution equationsdescribing the phase and amplitude modulation of nonlinear waves are physicallyinterpreted basing on the law of energy conservation. An algorithm reducing thegoverning nonlinear partial differential equations to their normal form isconsidered. The occurrence of resonance at the expense of nonlinear mult...
