Review
"One of the great science classics of the 20th century.... This is the book that provided the inspiration that gave birth to molecular biology and the discovery of DNA." Research News and Opportunities in Science and Theology

"...delightful...Schrödinger writes in a naturally relaxed and pleasant tone that leads us through the difficulties of his subject...It is well worth the trouble. For the serious student of origin-of-life theories, it is the obvious place to start." The Boston Book Review

Product Description
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' by 'a great man to whom I owe a personal debt for many exciting discussions'. It appears here together with Mind and Matter, his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times. Schrodinger asks what place consciousness occupies in the evolution of life, and what part the state of development of the human mind plays in moral questions. Brought together with these two classics are Schrödinger's autobiographical sketches, published and translated here for the first time. They offer a fascinating fragmentary account of his life as a background to his scientific writings, making this volume a valuable additon to the shelves of scientist and layman alike.

5.0 out of 5 stars Not leading edge, but a highly readable classic., August 25, 2002

By	Earl Dennis (San Francisco, California United States) - See all my reviews

It is not surprising that a genius would have interesting things to say. Physicist Erwin Schrodinger was an affable genius whose comments about life, molecular biology, mind, qualia, and a number of topics are interesting and relevant even today.

This edition of 'What is Life?' by Cambridge University Press also contains Schrodinger's essay entitled 'Mind and Matter,' along with some autobiographical notes. What is Life? is a well paced 1944 version of molecular genetics that is still valid today. Crick and Watson didn't discover the structure of DNA til 1953, so Schrodinger didn't know of replisomes and error correcting polymerase III, but this essay shows how well developed molecular biology was by this time. Crick and Watson were certainly in the right place at the right time by clearing up a minor bottleneck in the broader science of molecular genetics. Mainly what Schrodinger, the formulator of the quantum mechanical wave equation of atoms, wants to accomplish is to reconcile quantum effects with biology. What is Life? makes an excellent synthesis of quantum physics and biology. Where modern scientists like physicist Roger Penrose and chemist Graham Cairns-Smith fail at this correlation Schrodinger is eminently successful. Although this essay is somewhat dated it is stimulating and rewarding to read.

The second essay entitled 'Mind and Matter' written in 1956 is very similar to modern efforts in describing abstract neuro and cognitive science. It tackles many of the same topics as moderns Daniel Dennett, Gerald Edelman, and Antonio Damasio do. Schrodinger artfully blends the idealism of Schopenhauer with his own personal physicist's point of view and crafts a perfectly enjoyable, reflective discussion on the concept of mind. I actually enjoyed Mind and Matter more than What is Life? as it showed the intellectual range of Schrodinger better. His discussion of what he calls objectivation, or how the subjective and objective dynamics of the scientific observer influence one another was great.

Lastly, a brief selection of Schrodinger's writing about his own life rounds out this brief, thoughtful collection of essays by a world class scientist. This relaxing little book still exhibits the ability to invoke serious thought about the nature of life and the implications of consciousness.

4.0 out of 5 stars Scaled up quantum theory that tries..., January 20, 2000

By A Customer

...and almost succeeds in uniting the dissimilar worlds of Biochemistry/cellular mechanics with the subatomic and atomic worlds. Undoubtedly if this book (series of essays/thoughts/lectures) had been written twenty years later, it would be quite different, but as is, it makes some startlingly accurate predictions about the nature of heredity in biological systems. This book is NOT 'quantum mechanics explains life', it is however, the masterwork of one of quantum theories brightest stars, relating the abstract world of subatomic particles to, well, DNA, before anyone knew what it did. Alas, for poor Schrodinger, probabalistic interpretation is much less useful at such a macroscopic level, and the mathematics behind even 'good approximations' of VERY SMALL macromolecules are nearly infinitely more complex than those for, say helium, which cannot be solved exactly (too many variables) itself. But he knew that already, and shows it here. But regardless of any 'after-the-fact' criticism, Schrodinger built something palpable and incredible out of scaling and deduction from the quantum level up. The fact that he struck so close to the mark speaks volumes for the man and for quantum theory in general. Biology is rather more difficult to quantify with wave equations than an alpha particle...not that Schrodinger attempts such an undertaking here, but the point should be understood as pertaining to his background, at least. At any rate, this book is probably not the most pedestrian work one could find on the subject, nor the easiest read. It is however, some awfully foresighted ideas about nature, and is heartily recomended reading for anyone with an in-depth knowledge of biology and chemistry (quantum chemistry/physics would be a good *background* course here), and should be required reading for any molecular biology/biochemistry regimen. This book deserves five stars, and if it wasn't for that article in the late fifties that used quantum tunneling theory to dispute the fact that DNA could be the genetic material of the cell, (not authored by Schrodinger, but using an extension of his ideas, as in most quantum computation) it would have gotten them. Barring that, this is, to my knowledge, the best book about life ever written by a physicist, and contains philosophical insight befitting the greatest sages and philosophers. Or Dr. Schrodinger.

5.0 out of 5 stars Book connects the hard sciences to the life sciences., April 23, 1997

By A Customer

What Is Life? Erwin Schrodinger This book is the compilation of a series of lectures by a Nobel Luareate in quantum physics and attempts to reconcile the biological requirements of living cells to the probabalistic nature of the atom as defined by quantum mechanics. These lectures were originally give in the 1940's and 50's prior to the discovery of DNA, RNA, gene mapping, and other techniques taken for granted by today's biologists. The basic tenant of quantum physics is that all atomic structure can be described only by the mathematics of probability. The exact orbit of an electron or its velocity cannot be determined. One can only state the probability of the location or velocity. Protons and neutrons are thought to change back and forth into one another in a random fashion. The very process of physical measurement introduces errors which preclude accurate measurements. This is modern physics - random events governed by probabilities. Compare this to the biology of living cells. Genetics reproduce specific inherited characteristic for generations. Why does the random atomic behavior not interrupt or change genetic traits? How does humanity think logically using randomly behaving atoms and hence molecules and compounds? This little book attempts and succeeds in theoretically reconciling these two worlds. The author predicts the structure of DNA. He anticipates current studies in how small numbers of randomly acting atoms are constrained to be deterministic. In the latter lectures, he enters the world of metaphysics to discuss "Mind and Matter, Determinism and Free Will, Ethics, and Science and Religion." This book is less than 300 pages long, but encylopic in scope. Be warned that it must be savored to be understood. It cannot be speed read nor can it be read only once to be understood. Finally, two much later in time companion books are "The Quantum Self" and "The Dancing Wu Li Masters" expand the concepts presented by this book. Both are available from Amazon. Joseph I.
