An experienced civil engineer presents the physics and fundamentals underlying the many fields of engineering. Far from a dry exposition, this unique primer probes real-world examples to show how the engineer’s way of thinking can illuminate questions from the simple to the profound: Why shouldn’t soldiers march across a bridge? Why do buildings want to float and cars want to fly? What is the difference between thinking systemically and systematically? This is an informative resource, offering many provocative insights into familiar principles.
