Science has its roots in human curiosity. It is the process of exploration and research that has led to a better understanding of our surroundings: Copernicus set the Earth in its right place in our models of the Universe, Charles Darwin elucidated the mechanism of the evolution of living species, and Albert Einstein brought out the intimate connection between energy, space, and time. This book provides a reliable guide to acquaint oneself with the scientific process. It explains in easy terms how scientific investigation has historically developed to reach our present understanding of the world around us. It also discusses the place of science in modern society in relation to culture and to the technological advances that it brings.
