This book applies basic principles of physics to conduct forensics-style re-examinations of several historical events. The authors familarize readers with introductory-level physics while demonstrating how physics concepts can be utilized to resolve historical debates about unsolved mysteries and controversial events. Each chapter introduces a new physics concept, then applies that concept to case studies in detail. The authors also identify the advantages of using case studies as a pedagogical approach to understanding physics. This second edition expands the number of physics principles and case studies covered. The book provides readers with the tools of a good forensic physicist and the ability to utilize them for real-world applications.
