As the most widely adopted new physics text in more than 50 years, Knight’s Physics for Scientists and Engineers was published to widespread critical acclaim from professors and students. In the Third Edition, Knight builds on the research-proven instructional techniques he introduced in the first and second editions, as well as national data of student performance, to take student learning even further. Knight’s unparalleled insight into student learning difficulties, and his impeccably skillful crafting of text and figures at every level-from macro to micro-to address these difficulties, results in a uniquely effective and accessible book, leading students to a deeper and better-connected understanding of the concepts and more proficient problem-solving skills.   For the Third Edition, Knight continues to apply the best results from educational research, and to refine and tailor them for this course and its students. New pedagogical features (Chapter Previews, Challenge Examples, and Data-based Examples), end-of-chapter problem sets enhanced through analysis of national student metadata, fine-tuned and streamlined content, and an even more robust MasteringPhysics® program take the hallmarks of the previous editions-exceptionally effective conceptual explanation and problem-solving instruction-to a new level.
