Physics 11E provides students with the skills that they need to succeed in this course, by focusing on conceptual understanding; problem solving; and providing real-world applications and relevance. Conceptual Examples, Concepts and Calculations problems, and Check Your Understanding questions help students to understand physics principles. Math Skills boxes, multi-concept problems, and Examples with reasoning steps help students to improve their reasoning skills while solving problems. “The Physics Of” boxes show students how physics principles are relevant to their everyday lives.
Available/sold separately, WileyPLUS to accompany Physics 11E continues to build on rich multimedia enhancements that encourage student engagement. ORION, the adaptive study guide, diagnoses student’s strengths and weaknesses, leading them to the specific content and media needed to help them effectively learn. All ORION practice problems have hints and feedback. The course includes 259 short lecture videos, one for each course section, that explain the basic concepts and learning objectives. In addition, 150 Chalkboard problem-solving videos and guided online tutorials along with vector drawing questions enrich WileyPLUS. These features are designed to facilitate flipping the classroom, and to encourage students to remain within the WileyPLUS environment, as opposed to pursuing the “pay-for-solutions” websites and searching uncurated web content that short circuits and can confuse their learning process.

David Young received his Ph.D. in experimental condensed matter physics from Florida State University in 1998. He then held a post-doc position in the Department of Chemistry and the Princeton Materials Institute at Princeton University before joining the faculty in the Department of Physics and Astronomy at Louisiana State University in 2000. His research focuses on the synthesis and characterization of high-quality single crystals of novel electronic and magnetic materials. He is the coauthor of almost 200 research publications that have appeared in peer-reviewed journals. Professor Young has received multiple awards for outstanding teaching of undergraduates.
Shane Stadler received his Ph.D. in experimental condensed matter physics from Tulane University in 1998. He went on to accept a National Research Council Postdoctoral Fellowship with the Naval Research Laboratory where he researched artificially structured magnetic materials. He then joined the faculty in the Department of Physics at Southern Illinois University before joining the faculty of the Department of Physics and Astronomy at Louisiana State University in 2008.
