A practical guide 'Spreadsheets for Chemists' shows chemists of all levels how to use spreadsheet programs in their daily work. It highlights the possibilities provided by Lotus 1-2-3, the most widely used spreadsheet program in the sciences. Apart from hundreds of example fragments, it features: * Detailed discussion of the most relevant functions and all the () macro commands. * An accompanying diskette containing 57 worksheets involving many different fields of chemical research and teaching. * An extensive glossary of spreadsheet terms. * Three appendices covering 1-2-3's competitors and add-in packages, the use of Windows-based spreadsheets and how what-if analysis and back-solving is applied. Although the disk examples were developed for Lotus 1-2-3 DOS Versions 2.x (x=2-4), the worksheets are compatible with the newer Windows versions and those of their main competitors, Borland's Quattro Pro and Microsoft's Excel. Several compatible spreadsheets (AsEasyAs, Proqube) might also be as used as inexpensive alternatives. The author is a senior scientist at the Nuclear Research Centre in Karlsruhe, Germany. He has been using spreadsheet software for nearly ten years successfully in a variety of chemical problems.
