'How Round is your Circle?' includes chapters on: hard lines; how to draw a straight line; four-bar variations; building the world's first rules; dividing the circle; falling aprat; follow my leader; all approximations are rational; all a matter of balance; and finding some equilibrium.

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.

Making is good for you. Exploring crafts can be relaxing and therapeutic : the projects in this book are accessible to anyone who is inspired to recycle old clothes and textiles into unique, decorative, useful projects. Our forbears improvised tools to recycle their worn clothes - mostly dark suiting or mill waste if they lived near a mill. Usually they made mats for their cold floors or as draft excluders across doors. Nowadays you can choose from so many more colors and textures - painting with rags! Try one project or more. You will be able to use the techniques to design and make your own one-off items for your home or as hand-made gifts. The techniques here are traditional and simple - you will be surprised at how drab fabrics become transformed. Simple designs work best and you can even improvise as you work. If a fabric runs out, then use another - I call that organic design! Hooking is the best technique for pictorial detail and different techniques could be combined for original wall art. Historically, rugs were made by several people sitting round a horizontal frame with the children cutting the pieces of rag which were prodded into the hessian (burlap) backing to make a shaggy mat. There is a prodded project (for purists) but you can also achieve the same effect without a frame by progging, which can be done on table or thigh (carefully). Warning – this craft can be addictive!
