If you are interested in how medieval cathedrals came into being, and the mathematics associated with their architecture and construction, then this book is for you.
'This book starts with the story of Larry Walters, who decided to try flying a garden chair with some fifty helium weather balloons attached. Larry didn't do the maths, and ended up at 16,000 feet! Michael de Smith has written a book for all the Larrys who need or ought to do some mathematical analysis of a problem before setting out.
