What Is Life (Attached with "My World View")

Schrödinger is one of the founders of quantum power in the 20th century and is also known as the "father of modern physics". He is famous in the public circle for the allusion of "Schrödinger's cat". This book is a speech delivered by Schrödinger in the 1930s, in which Schrödinger described his views on the nature of life. Different from common understanding, Schrödinger pointed out that the essential difference between life and non-life is that life can be self-sustaining, self-replicating, self-repairing and other properties, and these properties are based on the basic principles of quantum mechanics. This is of great value for us to think about the meaning of life.

When it comes to what life is, most people will answer it as a philosophical question, but Schrödinger introduced biology and physics to answer, thereby proposing the concept of entropy. Living organisms produce positive entropy, and then move toward the dangerous state of maximum entropy, that is, death. A system that is isolated or in a uniform environment will increase entropy. It's just like we place items randomly and are too lazy to put them in the right place, so we keep the organism at a relatively low level of entropy, allowing ordered things to go in and disordered things to flow out.

What is life? Regarding this issue, this book introduces to us his theories of "gene is a molecule", "life maintenance relies on continuous intake of order and discharge of disorder" and "entropy" in a popular science tone, which is very interesting. If you look through a high school biology textbook, you will find that the genetic theory in the first half of the book is very rigorous, which was very novel for me. After graduating from high school, knowledge once again touched my brain inexplicably. The subsequent discussion of negentropy surprised me even more. If I hadn't tried to read a boring book, I might not have known the balance between order and disorder in life.

Sometimes I wonder what life is. If there is life, why is there death? Why do we have to experience life, separation and death? It seems that Schrödinger's book only knows his theory of entropy increase. He combined physics and biology and put forward the famous saying "life depends on negative entropy for survival". Entropy is a measurable physical quantity. Living organisms continuously increase entropy and move toward maximum entropy, which is death. In order to avoid this state, living organisms can only maintain their survival by avoiding this state by constantly acquiring negentropy from the environment.

1944 Was the most anxious year of the Second World War. It was also the year when Schrödinger creatively integrated the strengths of various schools and integrated facts and theories under the premise of facing difficulties in the development of the discipline at that time. This book starts from the issues that classical physicists should study, including the basis of physical laws and the objects included in biological motion. It extends to various conceptual elaborations and logical judgments related to genetics; it can be said that while inheriting the old doctrine, it integrates its own creative judgments into it, and finally rises to the philosophical level, making scientific analysis and empirical judgment on the consciousness and will of human beings, a higher creature with both curiosity and feeling.

This book resonated with me, especially Schrödinger's view of combining biology with quantum mechanics, which reminded me of my own married life. As the book says, life is a complex and mysterious topic that requires us to constantly explore and understand. And I also deeply realized in my marriage that the relationship between two people is also so complicated and requires constant learning and adaptation. The content of this book is both profound and enlightening, making me think more deeply about life.

This is an introductory book to life sciences and is important for learning. It can also provide some ideas for research.

Physical biology, Schrödinger's whimsical ideas, and the many possibilities given to living things, can be used to make up for the lack of theory in biology [Like] [Like] [Like]
