This book presents a readable and accessible coverage of chemistry, decade by decade, during the twentieth century. Its primary audiences include high school and college chemistry teachers, their students, professional scientists and the lay public interested in science. Each decade is covered by a chapter with milestones, drawings, photographs, sidebars, a “scientist of the decade,” and recommended reading. Chapter 11 is titled: “The Early Twenty-first Century: A Chemical Odyssey.” There is a comprehensive list of Nobel Prizes in chemistry (1901-2000) as well as an extensive list of book, journal and website sources of information. There is simply no other book that has attempted this coverage in a manner accessible to a broad readership.
