Physics cannot show that a corporal, godlike figure exists in the universe. However, the major religions of the world, especially Christianity, describe God as a spiritual energy and not corporal. Quantum physics says there exists a universal energy that has the attributes of God. This energy has consciousness and creativity. All matter is composed of this energy. This energy was responsible for the Big Bang. Professor emeritus William Tiller, a physicist at Stanford University, has shown this energy can interact with human consciousness. This book takes you through a non-mathematical proof of the physics of these assertions.
The propagation of sound in a laboratory model consisting of a surface layer of water overlying a thick bottom layer of sand was experimentally investigated. The variations of pressure amplitude as a function of receiver depth, range, and transverse location were measured for the source at constant depth in the surface layer of water. Three frequencies for which only the lowest mode propagates were used in this investigation. The measurements of pressure amplitude as a function of depth and range were found in good agreement with normal mode theory, when absorption in the bottom was taken into consideration. Keywords include: Sound propagation, Shallow water, Normal modes, Shallow water facility, Theses.
The Handbook of Acoustics belongs on the reference shelf of every engineer, architect, research scientist, or designer with a professional interest in the propagation, control, transmission, and effects of sound.
This book represents the proceedings of the Conference on Underwater Acoustics, held in September 1992, to bring together all the various disciplines involved in a forum to present the latest research on all aspects of marine acoustics.
