A comprehensive introduction to physics is provided by this book which devotes many sections to basic physics and applications of fundamental principles. The text treats physics as an experimental science, not as an abstract discipline. It relates physics to everyday and other scientific fields, with an emphasis on life sciences and biology. There is extensive use of examples involving biological and chemical systems and alternative energy sources. Entire sections and chapters are devoted to applications of physics, covering subjects such as nerve conduction, ionizing radiation, and nuclear magnetic resonance.
