Here is a fascinating and nontechnical introduction to the ubiquitous effects of symmetry. Starting with geometrical elements of symmetry, the author reveals the beauty of symmetry in the laws of physics, biology, astronomy, and chemistry. He shows that symmetryand asymmetry form the founda tion of relativity, quantum mechanics, solid-state physics, and .ato mic, subatomic, and elementary particle physics, and so on. The author would like to attract the reader's attention to the very idea of symmetry and help him to discern a wide variety of the manifestations of symmetry in the surrounding world, and, above all, to demonstrate .the most important role played by symmetry in the scientific comprehension of the world and in human creative effort. And in the end is the dialogue with the Reader which is the style of Tarasov's other books on Calculus and Quantum Mechanics.
