Hot Molecules, Cold Electrons: From the Mathematics of Heat to the Development of the Trans-Atlantic Telegraph Cable
Paul J. Nahin, Princeton Univ. Press, Princeton, NJ, $24.95, 232 pages, March 2020, ISBN: 978-0-691-19172-0
Heat, like gravity, shapes nearly every aspect of our universe — from how milk dissolves in coffee to how molten planets cool. The heat equation, a cornerstone of modern physics, demystifies these processes and provides a mathematical illustration of heat diffusion through matter. This book presents the mathematics and history behind the equation, explaining how this foundational idea brought about one of the greatest technological advancements of the modern era.
Readers learn of the discovery, derivation, and solving of the heat equation in the nineteenth century by French mathematical physicist Joseph Fourier, as well as its application by Scottish physicist William Thomson to develop the trans-Atlantic telegraph cable. The cable reduced the time to transfer messages between continents from weeks to minutes. Anyone with a background in basic calculus and physics can understand the book’s mathematical and scientific explanations. Scientists and engineers will appreciate the accompanying MATLAB code, which aids readers interested in solving the heat equation themselves.
The Handbook of Continuous Crystallization
Nima Yazdanpanah and Zoltan K. Nagy, Royal Society of Chemistry, London, U.K., $175, 609 pages, Feb. 2020, ISBN: 978-1-78801-214-0
Continuous crystallization is critical to the fine chemical and pharmaceutical industries. It is an area of intense research, because improvements in continuous crystallization technologies can reduce costs and improve product quality, providing significant financial gains.
This book presents fundamental and applied knowledge related to this processing technique, paying particular attention to applications, scaleup, and process intensification. Beginning with crystallization techniques and control strategies, readers learn about experimental methods and computational tools. Case studies from fine and bulk chemical and pharmaceutical applications employ new mathematical tools that put theory into context. The handbook is suitable for...
