Matter and Interactions

Matter & Interactions is a calculus-based introductory physics text that reflects a modernized view of physics. It stresses reasoning from powerful physics principles and integrates contemporary insights such as the atomic nature of matter, quantized energy, and relativistic dynamics throughout the curriculum. Students engage in the full process of creating and refining physical models. Computational modeling is integrated to allow students to apply fundamental principles to more complex, realistic systems, and to explore the possible ranges of behavior of physical models.

Joining Ruth Chabay and Bruce Sherwood for this edition as authors are longtime collaborators Aaron Titus (North Carolina State University), and Stephen Spicklemire (University of Indianapolis) who have made great impacts on the new video series, interactive figures, and simulations.

The new edition is thoughtfully updated with extensive content revisions, including chapter and section level learning objectives, clarified and simplified initial presentation of key concepts and techniques, and the introduction of angular momentum earlier, before collisions.

Ruth Chabay earned a Ph.D. in physical chemistry from the University of Illinois at Urbana-Champaign; her undergraduate degree was in chemistry from the University of Chicago. She is Professor Emerita in the Department of Physics at North Carolina State University and was Weston Visiting Professor, Department of Science Teaching, at the Weizmann Institute of Science in Rehovot, Israel. She has also taught at the University of Illinois at Urbana-Champaign, Carnegie Mellon University, High Point University, and the University of North Texas. She is a Fellow of the American Physical Society and the American Association of Physics Teachers. Chabay lives in Oregon, where she enjoys the mountains, the ocean, the forests, and the Oregon wine country.

Bruce Sherwood's Ph.D. is in experimental particle physics from the University of Chicago; his undergraduate degree was in engineering science from Purdue University, after which he studied physics for one year at the University of Padua, Italy. He is Professor Emeritus in the Department of Physics at North Carolina State University. He has also taught at Caltech, the University of Illinois at Urbana-Champaign, and Carnegie Mellon University. He is a Fellow of the American Physical Society, the American Association of Physics Teachers, and the American Association for the Advancement of Science. Sherwood lives in Oregon.
In 2014 the American Association of Physics Teachers presented Chabay and Sherwood with the David Halliday and Robert Resnick Award for Excellence in Undergraduate Physics Teaching.

Aaron Titus is a Teaching Professor in the Department of Physics at North Carolina State University.
