Books by John Bryant

A midnight crime and a freak death at an animal sanctuary result in a disparate herd of rescued horses and ponies taking to the roads, led by their unique leader, 'Lady Patricia.' Does she have a destination in her mind? Why was the equine exodus raised in the House of Commons? Who is assisting her quest for freedom? Why is a former commando involved? Who wants to kill her?

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.

If you want to experience something, run a marathon' - Emil ZatopekThe London Marathon salutes 25 years of the London Marathon by exploring the incredible physical and mental challenge that lies at the very heart of marathon running.

The years 1953-54 marked the conquests of 2 unattainable peaks - Mt Everest and the Four Minute Mile. This is the story of the long quest for the 'Magic Mile', almost 200 years in the making. The methods the runners used, the secrets they uncovered, were passed through the generations, until the quest reached its climax on the 6th May 1954.
