The latest book from Cengage Learning on Thinking Through the Past, Volume I

This book asks researchers what uncertainty means for literacy research, and for how literacy plays through uncertain lives. While the book is not focused only on COVID-19, it is significant that it was written in 2020-2021, when our authors’ and readers’ working and personal lives were thrown into disarray by stay-at-home orders. The book opens up new spaces for examining ways that literacy has come to matter in the world.

This indispensable guide will equip the reader with a thorough understanding of the field of foaming chemistry. Assuming only basic theoretical background knowledge, the book provides a straightforward introduction to the principles and properties of foams and foaming surfactants. It discusses the key ideas that underpin why foaming occurs, how it can be avoided and how different degrees of antifoaming can be achieved, and covers the latest test methods, including laboratory and industrial developed techniques. Detailing a variety of different kinds of foams, from wet detergents and food foams, to polymeric, material and metal foams, it connects theory to real-world applications and recent developments in foam research. Combining academic and industrial viewpoints, this book is the definitive stand-alone resource for researchers, students and industrialists working on foam technology, colloidal systems in the field of chemical engineering, fluid mechanics, physical chemistry, and applied physics.

How rhetorical training influenced deeds as well as words in the Roman Empire
The assassins of Julius Caesar cried out that they had killed a tyrant, and days later their colleagues in the Senate proposed rewards for this act of tyrannicide. The killers and their supporters spoke as if they were following a well-known script. They were. Their education was chiefly in rhetoric and as boys they would all have heard and given speeches on a ubiquitous set of themes―including one asserting that “he who kills a tyrant shall receive a reward from the city.” In That Tyrant, Persuasion, J. E. Lendon explores how rhetorical education in the Roman world influenced not only the words of literature but also momentous deeds: the killing of Julius Caesar, what civic buildings and monuments were built, what laws were made, and, ultimately, how the empire itself should be run.
