With his vibrant and illustrative style, along with an increasingly refined didactics, Peter Atkins has revolutionized learning and teaching in physical chemistry. His style is distinctive and unparalleled. The 5th edition of the "little" Atkins for natural and engineering sciences features a new, innovative concept that helps overcome all obstacles. The material is divided into 15 focus chapters. At the beginning of each focus, connections between the sections within that focus are established to highlight the links between different areas of physical chemistry. Each section starts with a motivation, an outline of key ideas, and the prerequisites that readers should have to understand the section. Numerous worked examples, summaries, comprehension tests, and tips for the correct use of technical language help reinforce the learned concepts and enable targeted learning and revision. For the first time, the 5th edition also includes a workbook with worked solutions to over 800 problems. The "little" Atkins is and remains a must-have for anyone starting out in physical chemistry. It is also available in an attractive deluxe set with the workbook.
