First published in 1967. The impression is sometimes given that the Atomic Theory was revived in the early years of the nineteenth century by John Dalton, and that continuously from then on it has played a vital role in chemistry. The aim of this study is to revise this over-simplified picture. Atomic explanations seemed to chemists to go beyond the facts, to fail to lend themselves to mathematical expression, and to deny the ultimate simplicity and unity of all matter. Most, therefore, rejected them. Meanwhile, physicists were developing a whole range of atomic theories to explain the physical properties of bodies in terms of very simple atoms or particles. During the last thirty years of the century the position changed, as physicists and chemists came to agree on a common atomic theory. But the last prominent opponents of atomism were not converted until the early years of the twentieth century, by which time studies of radioactivity had made it clear that the billiard-ball Daltonian atom must, in any case, be abandoned.

The Principles of Biology sequence (BI 211, 212 and 213) introduces biology as a scientific discipline for students planning to major in biology and other science disciplines. Laboratories and classroom activities introduce techniques used to study biological processes and provide opportunities for students to develop their ability to conduct research.

In Molecules, bestselling author Theodore Gray demonstrates, through stunning, never-before-seen images and illustrations, how the elements of the periodic table combine to form the molecules that make up our world. Everything physical is made up of the elements and the infinite variety of molecules they form when they combine with each other. In Molecules, Theodore Gray takes the next step in the story that began with the periodic table in his best-selling book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Here, he explores, through fascinating stories and trademark stunning photography, the most interesting, essential, useful, and beautiful of the millions of chemical structures that make up every material in the world. Gray begins with an explanation of how atoms bond to form molecules and compounds, as well as the difference between organic and inorganic chemistry. He then goes on to explore the vast array of materials molecules can create, including: soaps and solvents; goops and oils; rocks and ores; ropes and fibers; painkillers and dangerous drugs; sweeteners; perfumes and stink bombs; colors and pigments; and controversial compounds including asbestos, CFCs, and thimerosal. Big, gorgeous photographs, as well as diagrams of the compounds and their chemical bonds, rendered with never before seen beauty, fill the pages and capture molecules in their various states. As he did in The Elements, Gray shows us molecules as we've never seen them before. It's the perfect book for his loyal fans who've been eager for more and for anyone fascinated with the mysteries of the material world.
