How do you draw a straight line? How do you determine if a circle is really round? These may sound like simple or even trivial mathematical problems, but to an engineer the answers can mean the difference between success and failure. How Round Is Your Circle? invites readers to explore many of the same fundamental questions that working engineers deal with every day--it's challenging, hands-on, and fun. John Bryant and Chris Sangwin illustrate how physical models are created from abstract mathematical ones. Using elementary geometry and trigonometry, they guide readers through paper-and-pencil reconstructions of mathematical problems and show them how to construct actual physical models themselves--directions included. It's an effective and entertaining way to explain how applied mathematics and engineering work together to solve problems, everything from keeping a piston aligned in its cylinder to ensuring that automotive driveshafts rotate smoothly. Intriguingly, checking the roundness of a manufactured object is trickier than one might think. When does the width of a saw blade affect an engineer's calculations--or, for that matter, the width of a physical line? When does a measurement need to be exact and when will an approximation suffice? Bryant and Sangwin tackle questions like these and enliven their discussions with many fascinating highlights from engineering history. Generously illustrated, How Round Is Your Circle? reveals some of the hidden complexities in everyday things.… (more)

This book is an interesting inspection into the practical problems of Engineering. While Mathematics is somewhat esoteric and deals with imaginary solutions and ideas, the consequences of Mathematics is very real. This book takes some problems in Engineering that might be trivial to a Mathematician and puts it into a real-world setting. For instance, how does one draw a straight line? With a Ruler or a Straight Edge, this answer is quite simple, but how does one produce a straight edge in the first place?

With plenty of projects and ideas for hands-on learning, this book can make an invaluable addition to your library. ( )
