H. W. Roesky K. Mockel Chemical Curiosities Spectacular Experiments and Inspired Quotes over 9000 copies of the German edition sold in 18 months The remarkable achievement of the "Roesky/Mockel" is the linkage between the world of the human spirit, expressed in literature and historical continuity, and the art of chemical demonstration. One expects Goethe to move freely in the pages of "Chemical Curiosities", but Whitman, Nietzsche, Thomas Mann, Salvador Dali, Montaigne, and the prophet Jeremiah! They serve too, authentically and ingeniously, in the authors deeply humanistic approach to science. The chemical and literary strands of this book are so ably intertwined. Roald Hoffmann

Written for calculus based general chemistry courses, particularly honours level or accelerated courses, Chemical Principles helps students develop chemical insight by showing the connections between fundamental chemical ideas and their applications. Unlike other texts, it begins with a detailed picture of the atom then builds toward chemistry's frontier, continually demonstrating how to solve problems, think about nature and matter, and visualize chemical concepts in the same ways as working chemists. The new edition incorporates features that extend the book's emphasis on modern techniques and applications while strengthening its problem solving approach. Atkins/Jones is the only book for this course featuring integrated book specific media that provides students with effective study help via a variety of electronic tools. The website at ... has been developed simultaneously with the text and offers a range of tools for problem solving and chemical exploration.

Most people remember chemistry from their schooldays as largely incomprehensible a subject that was fact rich but understanding poor smelly and so far removed from the real world of events and pleasures that there seemed little point except for the most introverted in coming to terms with its grubby concepts spells recipes and rules Peter Atkins wants to change all that In this Very Short Introduction to Chemistry he encourages us to look at chemistry anew through a chemist s eyes in order to understand its central concepts and to see how it contributes not only towards our material comfort but also to human culture Atkins shows how chemistry provides the infrastructure of our world through the chemical industry the fuels of heating power generation and transport as well as the fabrics of our clothing and furnishings By considering the remarkable achievements that chemistry has made and examining its place between both physics and biology Atkins presents a fascinating clear and rigorous exploration of the world of chemistry its structure core concepts and exciting contributions to new cutting edge technologies ABOUT THE SERIES The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every sub
