Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the twentieth century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman, but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. The philosopher Karl Popper hailed it as a "beautiful and important book." It appears here together with Mind and Matter, his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times. Brought together with these two classics are Schrödinger's autobiographical sketches, published and translated here for the first time, which offer a fascinating fragmentary account of his life as a background to his scientific writings.--Publisher description.
