Order and Disorder is a non-mathematical introduction to the most important ideas in sciences for university students not majoring in a scientific area. The objective is to prepare non-science students to make life and political decisions involving science and to understand the advances in sciences as covered and reported in the mass media. The book is significantly comprehensive in physics and chemistry, providing the essential background to discuss and gain a better appreciation of selected topics in biological and neurological sciences, as well as astronomy and geology. The topics are integrated with the recurring theme of order and disorder the organization achieved in the face of its never-ending drive towards disorganization. The book also lends an insight into some considerations in the philosophy of science, as well as the applications of science to health and to a variety of professions. Reading experience is enhanced by the provisions of illuminating examples, supplementary readings and a summary for each chapter. New terminologies, that appear for the first time in the content, are set off in bold italics and annotated in the glossary. Where basic principles are introduced and explained, these are highlighted prominently in bold for ease of reference. Stimulating discussion questions are presented at the end of each chapter, giving readers some food for thought.
