What Is Life is a seminal work by the Nobel Prize-winning physicist and pioneering molecular biologist Erwin Schroedinger. For enthusiasts of physics, this book is a must-read.Schroedinger explores the essence of genetic phenomena in biological organisms through the lens of physics, delving into the significant role of consciousness in the evolution of life. With engaging prose, he guides readers through daunting topics such as the mysterious genetic code, the emergence of mutations, molecular stability, aperiodic crystals, order and disorder, life and entropy, and the natural selection of consciousness and behavior. This work breaks down the boundaries between physics and biology, offering us a glimpse into the past, present, and future of life.What Is Life inspired scientists to investigate life’s mysteries from the perspective of microphysics, directly leading to the birth of molecular biology. Its contents created a stir in academic and intellectual circles, earning Schroedinger the praise of renowned contemporary physicist Simone as "a remarkable philosopher among physicists."
