Paul Hewitt's best-selling Conceptual Physics defined the liberal arts physics course over 30 years ago and continues as the benchmark. Hewitt's text is guided by the "principle of concepts before calculations" and is famous for engaging students with real-world analogies and imagery to build a strong conceptual understanding of physical principles, ranging from classical mechanics to modern physics. The 13th Edition continues to make physics delightful for students with informative and fun Hewitt-Drew-It screencasts, updated content and applications, and new engaging activities.
