This book presents original research results on the leading edge of physics. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum, including novel ways for manufacturing extremely high-effective solar cells; the possibility of superluminal computing for hypercomputation; selected problems of philosophical reflection of freedom in physics; quantum entanglement in connection with dark energy- from historical to modern theories; laser-induced breakdown and detonation in gas-particle and gas-droplet mixtures; the paleo classical interpretation of quantum theory; and minimal length, measurability, continuous and discrete theories.
