This is a perfect example of the most rarest of all things: a technical book that is an utter joy to read.
I have no engineering, maths or physics beyond GCSEs, and was concerned that the book would quickly go over my head. However, Gordon writes with a clarity and simplicity that makes the material accessible. He discusses the main concepts in structural engineering, and gives hundreds of examples, from plants to skeletons to boats to planes and buildings. Occasionally I got lost by the formulas or discussions of maths , but not only was that very rarely, it was also down to my own ignorance.
The real joy of this book is Gordon himself: his personality comes across wonderfully in the text, and I was often left chuckling at his remarks. I'd never expected to laugh when reading a book on engineering. I've read many novels which couldn't compare to this book, in terms of the writing skill of the author. The final chapter, on the philosophy of chapters, is outstanding.
I can't recommend this book enough, whether you're specificly looking for a book on engineering, or whether you're simply looking for your next book.
