When Nicolaus Copernicus discovered the Earth wasn’t the center of the Universe, everything changed. When Frederick Miescher discovered DNA, everything changed again. When quantum physicists discovered our physical universe isn’t real, that it’s a hologram - everything ... wait! Nothing changed - yet. Now "Butterflies are Free to Fly: A New and Radical Approach to Spiritual Evolution" examines how quantum physics and recent scientific experiments are radically changing our understanding of life, our reality, and our spirituality, giving us a new model for the way our universe works and the practical steps to take toward true joy and excitement and peace of mind.

The work of acoustical professionals is to mitigate the problems as much as possible given the constraints of time, money and practicality. For our purposes, practical room acoustics can be divided into two categories: less noise and better sound. Or in acoustical terms, soundproofing and room treatments. This book focuses on Architectural Acoustics, which is essentially human-audible sound in and around rooms of different sizes and shapes. Our intention is to simplify practical room acoustics for n ...
