The book of Erwin Schrodinger about life evokes a variety of basic questions concerning the understanding of life in terms of modern physics rather than biochemistry. Problems of organization and regulation of biological systems cannot be understood by revealing only the chemical processes of the living state. A group of reputable physicists - among them the followers of Heisenberg and Frohlich - and biologists came to this same conclusion though several workshops on this topic. This book contains their contributions, written from different viewpoints of theoretical physics and modern biology.
