This book investigates various aspects of information fields, not only theoretical, but with an additional emphasis on its applications. This book aims to provide a universal framework for understanding tempo-spatial information storage and communication in both quantum physical and biological regimes. This book is divided into two main parts: Part 1: this section introduces fundamental concepts of information fields theory within the physical realm, including well-established notions such as quantum potential and quantum entanglement. Part 2: this section addresses quantum fields phenomena in the biological realm, classified as biopsychical.
