For a one-semester course in liberal arts physics.
Hobson has four unifying themes: How do we know?, the significance of post-Newtonian physics (modern physics), energy, and the social context of physics. These themes become evident in the writing and pedagogy throughout the fourth edition.
New To This Edition
- Updated, extensively revised chapters on relativity:
- Cleanly separates special and general relativity chapters (Chapters 10 and 11), so instructors can present and omit material as they choose.
- All cosmological material is now gathered into Chapter 11, making this topic easier for instructors to teach.
- More modern, straightforward treatment of quantum physics Simplifies presentation for instructors and makes material more interesting; avoids the confusion associated with wave-particle duality.
- New and updated societal topics, such as nuclear terrorism Lends relevance and urgency to the material, demonstrating the importance of physics in students' lives and in society.
- Added and improved ''How Do We Know'' subsections Emphasizes the processes of science.
- Conventional terms and symbols used to replace several unconventional terms and symbols from the previous edition. For example:
- In the modern physics chapters, "v" rather than "s" is now used for speed.
- "Matter field" is now used instead of "psi field."
- Quantum "uncertainty" is now used instead of quantum "indeterminacy."
