Physics: An Illustrated Guide to Science is one of eight volumes of ''Facts On File's'' new ''Science Visual Resources'' set. Containing five sections, a comprehensive glossary, a Web site guide, and an index, ''Biology'' is an ideal learning tool for students and teachers of science. Full-color diagrams, graphs, charts, and maps on every page illustrate the essential elements of the subject, while parallel text provides key definitions and step-by-step explanations. The five sections include: ''Forces'' - provides an overview of Newton's laws of motion and gravity. It also describes the physics of simple machines and explains the distinction between the concepts of heat and work; ''Energy'' - examines the concept of energy in more detail. This section covers thermal conduction, radiation, and convection, as well as describes changes in energy type. The industrial production of energy as well as possible sources of renewable energy are also described here; ''Waves, Sound, and Light'' - is concerned with the wave motion of light and sound energy. The principles of superposition, interference, diffraction, polarization, and reflection are covered in this section. There is also a survey of lenses and optical instruments; and ''Electricity'' - details the basic concepts of electrical energy and magnetism. Subjects covered in this section include induction, electrostatics, electric current, electromotive force, electrolysis, transformers, and electric motors. It also includes: ''Electronics'' - is an overview of the practical issues involved in the design of devices that control the flow of electrons or other charged particles. It includes a comprehensive guide to circuit symbols, a look at microprocessors, and a thorough grounding in circuit logic.
