MODERN PHYSICS presents the latest discoveries in physics, and offers a contemporary and comprehensive approach with a strong emphasis on applications. In order to illustrate the process behind scientific advances and give students a historical perspective, the authors discuss the experiments that led to key discoveries covered in the text. A flexible organization allows you to select and teach topics in your preferred sequence without compromising your student's learning experience. A sound theoretical foundation in quantum theory is included to help physics majors succeed in their upper division courses.
- This new edition features revised sections on Neutrino Oscillations, Matter-Antimatter, and Grand Unifying Theories (in Chapter 14) along with Chapter 15's new Special Topic box on Gravitational Wave Detection for expanded coverage of topics and improved clarity.
- Chapter 16 features a new section on "The Standard Model of Cosmology," a new sub-section on "Olber's Paradoz," and a revised and updated Special Topic box on the "Future of Space Telescopes."
- In order to keep the text fresh and current, a variety of the questions and problems are completely new to this edition.
- Throughout the text, a focus on the history of physics offers a human perspective and helps students understand the context in which scientific advancements have been made.
- Special Topic boxes are up-to-date applications of interest to physicists and engineers. These features show the relevance of modern physics to the real world and allow students a more in-depth look at particularly engaging topics like gravitational wave detection, the "Age of the Earth," neutrino detection, and scanning probe microscopes.
- End-of-chapter problems include over 200 questions and more than 700 problems, providing you with ample material from which to select homework assignments without repeating the same problems every year. More challenging problems are flagged to help students gauge their progress from easier to harder problems.
- Blue margin notes help guide students to important concepts for easy review.
- End-of-chapter summaries give students a quick overview of topics covered in the chapter.
- Updates on experiments and discoveries in each chapter keep the text interesting and timely.
- A large number of examples, including the Conceptual Examples introduced in the last edition, give students ample practice applying the theories they read about in the text. Examples feature a Strategy step, which helps students identify the essential steps in problem solving and improve their problem-solving skills.
- Chapter 16, "Cosmology," has been rewritten to reflect the latest research and findings and expose students to this rapidly changing body of knowledge.
- The MODERN PHYSICS Instructor's Resource CD-ROM, available to adopters, includes such dynamic lecture tools as PowerPoint® lectures, 200 pieces of line art from the text, and PDF files of the Instructor's Solutions Manual.
- The authors illustrate the importance of individual ingenuity throughout the book with short biographical features highlighting the achievements of physicists throughout history.
- A flexible organization of content makes this text appropriate for a one- or two-semester course, giving you a choice of topics without compromising overall student learning. The authors begin by laying the historical groundwork for modern physics and then go on to in-depth coverage of relativity and quantum mechanics. The latter part of the book is devoted to the sub-fields of physics (atomic, condensed matter, nuclear and particle) along with general relativity and cosmology. This organization gives you a solid foundation for the course early in the book, and then lets you draw from the later chapters of the book to enhance your teaching with additional topics of your choosing.
