This highly unusual book is a serious inquiry into Schroedinger's question, "What is life?", and at the same time a celebration of life itself. It takes the reader on a voyage of discovery through many areas of contemporary physics, from non-equilibrium thermodynamics and quantum optics to liquid crystals and fractals, all necessary for illuminating the problem of life. In the process, the reader is treated to a rare and exquisite view of the organism, gaining novel insights, not only into the physics but also into "the poetry and meaning of being alive". This book is intended for all who love the subject.
