"What is Life?" is a scientific exploration that delves into the intersection of physics and biology. The book presents the idea that life, at its most basic level, operates according to the laws of physics and chemistry. It introduces the concept of an "aperiodic crystal" that contains genetic information in its configuration of covalent chemical bonds, which later inspired the discovery of the structure of DNA. The book also discusses entropy and negentropy, suggesting that life feeds on negentropy to counteract the natural process of increasing entropy.

This book is a fascinating exploration of animal behavior by a renowned zoologist. It delves into the author's personal experiences and observations of animals in their natural habitats, focusing particularly on birds, dogs, and jackdaws. The author uses these observations to draw conclusions about animal psychology and behavior, often comparing it to human behavior. The book is named after the biblical King Solomon, who was said to have a ring that allowed him to understand the language of animals.

This book presents a groundbreaking exploration of human sexuality, arguing that sexual repression leads to various psychological disorders. The author, a psychoanalyst, introduces the concept of "orgastic potency", which is an individual's ability to fully surrender and discharge pent-up sexual energy during the sexual act. He contends that societal norms and moralistic attitudes towards sex often hinder this release, leading to various neuroses and other psychological issues.

This seminal work in the field of genetics presents the results of a series of experiments conducted on pea plants, which led to the discovery of fundamental laws of inheritance. The author meticulously cross-bred different varieties of peas and meticulously recorded the traits of their offspring, leading to the formulation of the principles of segregation and independent assortment. These principles, which underpin modern genetics, explain how traits are passed from parents to offspring and how different traits are inherited independently of each other.
