The passage discusses two significant contributions to the field of mathematics and chemistry. In mathematics, it highlights Carl Boyer's book, which traces the development of modern calculus from its early origins to the present, emphasizing the contributions of various mathematicians such as Newton, Maclaurin, Bernoulli, Euler, and Lagrange. The book is praised for its engaging narrative and comprehensive coverage of the basic concepts. In chemistry, the passage reviews Dr. Wilfred W. Scott's fifth edition of "Standard Methods of Chemical Analysis," edited by Prof. N. Howell Furnam. This manual, covering both pure and applied analysis, has expanded to 2,700 pages, reflecting the rapid growth of analytical chemistry. The first volume focuses on the analysis of important chemical elements, with new methods for gallium, germanium, hydrogen, oxygen, and rhenium. The second volume covers sampling, applied analysis, and special techniques, including acidimetry, alkalimetry, gas analysis, metallography, and spectrographic analysis. The manual is noted for its accuracy and the inclusion of an author index, making it an essential resource for analytical chemists.The passage discusses two significant contributions to the field of mathematics and chemistry.
