This column is devoted to looking at a particular technological system - machines. Machines can be simple or complex and are used throughout the ancient and modern worlds. For example, the wheel is a simple machine found in the ancient world, yet indispensable in the modern world. However, the lawn mower is a complex machine invented in modern times and unheard of in the ancient world. As children learn about machines past and present, how they operate and how they are used, they gain a sense of how humans have controlled their world over time.
