Young learners will explore what a screw is and how it is useful.

Pressing Down explores the benefits and uses of the lever. RobbO and RobbEE learn how a lever can be formed in three different ways to do different kinds of work--lift and lower, separate, and open.

The author aims to show how the emergence of intelligent and autonomous bombs and missiles equipped with artificial perception and decision-making capabilities represents a profound historical shift in the relation of human beings both to machines and to information.

In War and Conflict in the Middle Ages, Stephen Morillo offers the first global history of armed conflict between 540 and 1500 or as late as 1800 CE, an age shaped by climate change and pandemics at both ends. Examining armed conflict at all levels, and ranging across China and the central Asian steppes to southwest Asia, western Europe, and beyond, Morillo explores the technological, social, cultural, and environmental determinants of warfare and the tools and tactics used by warriors on land and at sea. Part I explains the geographical, political, and technological rules that shaped patterns of military activity everywhere. Part II explores how these rules played out in various historical contexts. Armed conflict played a central role in the making of the medieval world, and medieval people used war and conflict to create, expand, and defend their communities and identities. But the devastating effects of climate change and epidemic disease continually reshaped these communities and the nature of their conflicts. Broad in its scope and rich in detail, War and Conflict in the Middle Ages will be the go-to guide for students and aficionados of military history, medieval history, and global history.

This book uses history in two ways: as the source of ideas about strategy and as examples to illustrate the elements by showing their application to specific campaigns and their utility in understanding the role of strategy in military operations. The focus is on American military campaigns from the American Indian Wars to the War in the Gulf. Those case studies are used to illustrate the strategy behind land, sea, and air campaigns. Over a fifth of the book examines the U.S. war against Japan because it furnishes such fine examples of independent and interdependent operations on land, on the sea, and in the air. The cases studied are not only intended to illustrate strategic ideas but also to show the utility of the author's distinctive approach to organizing military strategy. The book will appeal to military professionals, students of military science, and enthusiasts.
