| Like its predecessor, An Introduction to Physical Science, second edition, isdesigned to give students sufficient knowledge of the fundamental concepts ofphysical science to understand their physical environment and so gain an in-sight into their time and place in the world in which they live, This textbook, written primarily for first-year college students, presentsbasic concepts in the five major areas of physical science--astronomy, chemistry, geology, meteorology, and physics. Our knowledge of such things as thesolar system, the chemical periodic table, atomic theory, position, motion,equations, waves, minerals, and the elements of weather is based upon con-cepts of mass, time, space, force, and energy. The approach to physical sci-ence in this hook is essentially a presentation of these concepls and theirmany and varied relationships. The treatment of the subject matter is both descriptive and quantitative,with the relative emphases of these two approaches left up to the instructor.In this edition, most derivations of equations of the first edition have beenplaced in the appendix for use by [hose who wish to know the origin of suchequations. For the instructor who wishes to take the descriptive approachonly iu teaching physical science, it is suggested that all problems at the endof the chapters be omitted and that only the questions be used. In this edition of the textbook Chapters 1-11 present elements of bothclassical and modern physics. Chapters 12-16 cover important concepts inchemistry, while Chapters 17-20 are concerned with astronomy. Concepts inthe areas of meteorology and geology are discussed in Chapters 21~26 and27-31, respectively. By selecting chapters from the five major areas the instructor can orga-raze his course as he sees [it, or he may simply choose those topics needed farhis particular course. Specifically, the book is planned for use with or with-out a laboratory course under the two semester system. Credit hours for a se-mester s work can range from tbree to five hours, depending on the amount ofmalerial covered. It is suggested that the material on physics and chemistry |
