The Universe

In this book the author gives a complete picture of the physical laws that appear to regulate the functioning of the Universe from the atomic to the cosmic world. The book makes a description of the main fields of physics: classical physics, relativity, quantum mechanics and particle physics as they are applied to the atomic world and the cosmos to describe how the whole Universe has evolved to the present state. The description concentrates on the essentials, describing our present knowledge of those physical laws and outlining our limitations in understanding the whole picture. The description is done essentially without equations, except for a few important and simple ones. The text includes a short Annex for mathematically inclined readers who wish to see how the physical principles and laws expressed in words can be visualized in the language of mathematics. However, the book can be read totally without referring to that Annex. Also, The Universe explains in depth those laws and outlines their limitations. However, the author does it in a simple language that should be understandable to non-specialists. In particular, the author occasionally uses two young characters placed in various situations to explain the physics involved in those situations by means of their observations. The author uses also numerous simple pictures and graphics that make the text more easily comprehensible. von Vanier, Jacques
