The development of calculus is traced by Carl Boyer, who presents a vivid and fearless account of its evolution from ancient times to the present. The book focuses on the foundational concepts of modern calculus, providing a stimulating overview of its history. It includes a comprehensive bibliography and is an important addition to mathematical literature. The fifth edition of "Standard Methods of Chemical Analysis" by Dr. Wilfred W. Scott is a comprehensive manual for analytical chemists and advanced students. It consists of two volumes, covering 2,700 pages, an increase of nearly 1,000 pages from the fourth edition. The first volume covers analytical methods for chemical elements, with many chapters expanded and rewritten. New methods for gallium, germanium, hydrogen, oxygen, and rhenium are included, though some methods are incomplete. The second volume has undergone significant changes, divided into two parts. Part 1 deals with sampling and applied analysis, with chapters updated and expanded. Part 2 covers special techniques, including acidimetry, alkalimetry, gas analysis, and spectrographic analysis. The manual is free from errors, though some typographical issues exist. The revision has greatly enhanced its value for analytical chemists.The development of calculus is traced by Carl Boyer, who presents a vivid and fearless account of its evolution from ancient times to the present.
