Written at a level accessible to nonspecialists, including high-school students, college students in introductory courses, and the general public, this encyclopedia's purpose is to assist users in acquiring knowledge and understanding of chemistry. The 509 alphabetically arranged, signed articles were written by subject specialists and range from concise definitions to multiple-page overviews. Broad areas covered include analytical chemistry applications, biochemistry, biographies, elements, energy, environmental chemistry, medicine, organic chemistry, physical chemistry, reactions, states of matter, and structure. Examples of specific article titles are Alchemy; Artificial sweeteners; Boron; Clones; Franklin, Rosalind; Isomerism; Mole concept; Nanochemistry; Rubber; Spectroscopy; and zwitterions. In addition to explaining scientific principles, this set relates chemistry to everyday life. For example, Silly Putty (a silicone-based material) is a "liquid solid," the color of hydrangeas is determined by soil acidity, and endorphins may allow marathoners' bodies to endure long races.
