The new INQUIRY INTO PHYSICS, Fourth Edition maintains the perfect balance of quantitative and conceptual material by carefully incorporating problem solving into a discernible conceptual framework. The text integrates simple mathematics so students can see the practicality of physics and have means of testing its validity. Throughout the text, Ostdiek and Bord emphasize the relevance of physics to our daily lives. Students will find applied examples throughout the chapters, such as music synthesizers, liquid mirror telescopes, and nuclear-powered spacecraft. The text also periodically reviews the historical development of physics, material that has proven popular with liberal-arts majors using earlier editions.
