A concise introductory text on solid mechanics. This book presents the foundations of stress, strain and elasticity theory and consistently employs the use of vectors and Cartesian tensor notation.

In essence, this text is written as a challenge to others, to discover significant uses for Cayley number algebra in physics. I freely admit that though the reading of some sections would benefit from previous experience of certain topics in physics - particularly relativity and electromagnetism - generally the mathematics is not sophisticated. In fact, the mathematically sophisticated reader, may well find that in many places, the rather deliberate progress too slow for their liking. This text had its origin in a 90-minute lecture on complex numbers given by the author to prospective university students in 1994. In my attempt to develop a novel approach to the subject matter I looked at complex numbers from an entirely geometric perspective and, no doubt in line with innumerable other mathematicians, re-traced steps first taken by Hamilton and others in the early years of the nineteenth century. I even enquired into the possibility of using an alternative multiplication rule for complex numbers (in which argzlz2 = argzl- argz2) other than the one which is normally accepted (argzlz2 = argzl + argz2). Of course, my alternative was rejected because it didn't lead to a 'product' which had properties that we now accept as fundamental (i. e.

This substantial book features poems from the five decades of John Powell Ward's career. It opens with early, uncollected pieces – some of which were experimental and concrete – moves on to the traditionally styled poems of the 70s and 80s and then towards a late flowering in the 90s, which features a startling shift in style and a new focus on letters and the alphabet. His wider concerns: history, the human peril to the natural world, tragic public events (such as the King's Cross Fire), are played out across a formal grid of beautiful complexity. These strikingly original, ambitious poems are both profoundly moving and technically adroit. This volume offers the reader a wide selection from the author's six published books, along with several new poems."In no other time but our own, perhaps, would a poet feel obliged to wrap up his moralizing in such delicate phraseology, or make such a backdoor affair of his faith. Ward, however, manages brilliantly, combining an uncompromising integrity with a contemporary flair for understatement... One is left with the impression of having been told the truth cleanly and with warmth." The Times Literary Supplement"A major contribution to late twentieth century poetry."Bulletin of the Welsh AcademyJohn Powell Ward was born in Suffolk and educated at the Universities of Toronto, Cambridge and Wales. Editor of Poetry Wales from 1975 to 1980, he is the author of critical works on Wordsworth and R.S. Thomas among others, and editor of the Border Lines series. He has also published several volumes of poetry.

This book is intended as an introductory text on Solid Mechanics suitable for engineers, scientists and applied mathematicians. Solid mechanics is treated as a subset of mathematical engineering and courses on this topic which include theoretical, numerical and experimental aspects (as this text does) can be amongst the most interesting and accessible that an undergraduate science student can take. I have concentrated entirely on linear elasticity being, to the beginner, the most amenable and accessible aspect of solid mechanics. It is a subject with a long history, though its development in relatively recent times can be traced back to Hooke (circa 1670). Partly because of its long history solid mechanics has an 'old fashioned' feel to it which is reflected in numerous texts written on the subject. This is particularly so in the classic text by Love (A Treatise on the Mathematical Theory of Elasticity 4th ed., Cambridge, Univ. Press, 1927). Although there is a wealth of information in that text it is not in a form which is easily accessible to the average lecturer let alone the average engineering student. This classic style avoiding the use of vectors or tensors has been mirrored in many other more 'modern' texts.
