The book makes one wonder what the outcome would have been if he was given far more timely attention for his, at that time, unconventional theories of long range penetration and supply. On the other hand, it makes one wonder if he would have amounted much in today's athmosphere of the 'politically correct society' with his "amazing success in his getting himself disliked by people who are only too ready to be on his side", with his abrasive way of getting things done. It may well be a classic example of the adage that 'genius is never appreciated in one's time.' But many exalted figures in history considered him a military genius--the authors made it plain and clear there were many detractors too, from the ordinary soldier to Field Marshall Slim's unjust inferences in his post war memoirs.
My only complaint: the maps in the book--one gets the impression they were done in a hurry; the places mentioned which are crucial to the events described cannot be found, and I found myself having to use different atlases.
In retelling this story, the authors proved once more the truth in the saying that two heads working together are better than one.
Wingate has finally been given his due in this book. His true worth as an Army officer is finally exposed: As great as Lawrence but lacking the literary gifts.
A must-read for the professional Army or Marine Corps officer!

Colin McPhee conveys many interesting things like when bad luck happened in his home in Sayan and how they had to do a purification ceremony in regards to dispel the demons, witches and evil spirits. His wanderings in Bali to record music and study their music like the rare gamelan angklung and gamelan selonding from Tenganan who were the Bali Aga. Colin McPhee was drawn to the scintallinating sounds and metallic shimmer from the gamelan. At times there are humours accounts of what goes on between him and his friends that happen in the village or when they are touring around Bali. I found it enjoyable because, he seemed to have fitted in well with the Balinese people without too much problems compared with other writers before them spoke of barbarity and the animal like behaviour of the Balinese at certain functions. He writes with passion about what goes on and how things have changed with the colonial rule of the Dutch. The loss of autonomy by the Rajas who were reduced to poverty at times and how their obessions with cockfighting led to their ruin. Yet in times of despair and hardship they are always humble to him.
Overall the book contains a few photographs of his friends and colleagues. I found it wonderful and intriguing and as well as captiviting at times which he covers so many topics like the temple functions like Galungan, Wayang Kulit (Shadow Plays), the music club etc... This book you will grow to love like the book written by Miguel Corrovabias "Island of Bali".
When I found this book, I was almost certain I wasn't going to be disappointed. I was right. Consider, for instance, the blurb at the back of the book: "The graveryard, moreover, was a natural meeeting-place for witches and sorcerers, for every village had its suspects, owneres of books of spells that enabled the reader to change himself into a leyak--a ball of fire, a giant rat, or even a riderless motor cycle that travelled backwards. In this magic state sorcerers were indeed dangerous; they could send a man out of his wits or bring him to a lingering death."
Written by a musician, it doesn't fare so badly as a literary read. It captures the magic, mysticism, and soul of a place. A Bali experience is a sensory overload. Colin McPhee happily immersed himself in it and did a very impressive job.

Wow! Was she ever right! First of all, the book is written in a clear and pleasant conversational style. The author does not hesitate to bring in examples or to show diagrams to clarify an idea. Indeed, with a subject such as knot theory, diagrams are essential! His use of exercises is well justified however, I would say that many laypersons are unfamiliar with proof techniques and thus might have some difficulties with several of those. Algebra is used sparingly at best as Adams prefers to let his words and images convey the ideas.
All in all, I would say that this book does a wonderful job of relating a subject which is at the forefront of mathematics, to the mathematically uninitiated. Hopefully, it will stimulate even further interest.

Surprisingly complete for an introductory text, it is also amazingly understandable. Requiring only knowledge of polynomials and a mind capable of understanding twists, I found it addictive. This is one area where it pays not to think straight. After reading it twice, I still pick it up and scan it in odd moments. Problems are scattered throughout the book, and many can be solved using only a piece of string. Those that are still unsolved are clearly marked, with is good, since the statements are often very simple.
There are many applications and the number is growing all the time. One of the most profound images and statements of discovery was the pictures of the knotting of the rings of Saturn and commentator Carl Sagan saying, "We don't understand that at all. We will have to invent a whole new branch of physics to understand it." The most esoteric recent explanation of the structure of the universe is the theory of superstrings, where all objects are multi-dimensional knots. A fascinating problem in molecular biology of the gene is the process whereby DNA coils when quiescent and uncoils to be copied. One chapter is devoted to applications, although more would have been helpful.
A non-convoluted introduction to the theory of convolutions, this book belongs in every mathematical library.

Chapter 1 is an introduction to the basic terminology of knot theory, and the author gives examples of the most popular elementary knots. He points out the historical origins of the theory, one of these being the attempt by Lord Kelvin to explain the origins of the elements, interestingly. The basic operations on knots are defined, such as composition and factoring, and the famous Reidemeister moves. The proof that planar isotopies and Reidemeister moves suffices to map one projection of a knot to another is omitted. After defining links and linking numbers, the author then discusses tricolorability, and uses this to prove that there are nontrivial knots.
Chapter 2 then overviews the strategies used in the tabulation of knots.The Dowker notation, used to describe a projection of a knot, is discussed as a tool for listing knots with 13 or less crossings. The author also discusses the Conway notation, and how it is used to study tangles and mutants. Graph theory is also introduced as a technique to study knot projections. The author discusses the unsolved problem of finding an elementary integer function that gives the prime knots with given crossing number, a problem that has important ramifications for cryptography (but the author does not discuss this application).
Since knots are complicated objects, then like many other areas in topology, the strategy is to assign a quantity to a knot that will distinguish it from all other knots. Such a quantity is called an invariant, and as one might guess, no one has yet found an invariant to distinguish all nontrivial knots from each other. In the last two decades though, new powerful knot invariants have been discovered, many of these being based on concepts from theoretical physics. In chapter 3, the author discusses the unknotting number, the bridge number, and the crossing number as elementary examples of knot invariants.
Chapter 4 is more complicated, in that the author shows how to use surfaces to assist in the understanding of knots. After discussing how to triangulate an surface and the concept of a homoeomorphism between surfaces, he introduces the Euler characteristic as an invariant of surfaces. Surfaces appear in knot theory as the space in the knot's complement, and the author introduces the concept of the compressibility of a surface, also very important in three-dimensional topology. Particular attention is paid to Seifert surfaces, which, given a particular knot, are orientable surfaces with one boundary component such that the boundary component is the knot in question.
Several different types of knots are considered in chapter 5, such as torus, satellite and hyperbolic knots. The latter are particularly interesting, since their study is part of the field of hyperbolic geometry, a subject that is now undergoing intense study. The author also introduces the theory of braids and the braid group. Not only are braids very important in the study of knots, but they have taken on major importance in cryptography and dynamical systems.
Chapter 6 is very interesting, and introduces some of the more contemporary topics in knot theory. The assignment of polynomials to knots goes back to the early 20th century, but it took the work of Vaughan Jones and his use of ideas from operator theory and statistical mechanics to provide polynomial invariants of knots that were much finer than the Alexander polynomial of the 1930s. The Jones polynomial however is not introduced the way Jones did, but instead via the Kaufmann bracket polynomial. The HOMFLY polynomial is introduced as a polynomial that generalizes the Jones and Alexander polynomials.
A few applications of knot theory are discussed in Chapter 7, such as the DNA molecule and topological stereoisomers. The author also discusses the applications of knot theory to the theory of exactly solvable models in statistical mechanics, a topic that has mushroomed in the past decade. This is followed by a brief overview of applications of knot theory to graph theory in chapter 8.
Chapters 9 and 10 are an introduction to knot theory as it relates to research in the topology of 3-dimensional manifolds and the existence of knots in dimensions higher than 3. The concepts introduced, particulary the idea of a Heegaard diagram, are used extensively in the study of 3-manifolds. In addition, the author mentions the famous Poincare conjecture, albeit in non-rigorous terms. The Kirby calculus, which is a kind of generalization of the Reidemeister moves, but instead models the sequence of operations that allow one to change from one Dehn surgery description of a 3-manifold to another is briefly discussed. The author also gives a few elementary, intuitive hints about how to visualize knotted objects in high dimensions.

As opposed to many entry-level books describing Bonsai species and their care, this book is organized around case studies.
The author expects the reader to know the basics of Bonsai and takes you from there...
I particularly liked the case study based on an Elm stump collected in the wild.
Highly recommended.
In all, I guess I have found his writing style and his knowledge base combine to provide a book that I will return to often to direct my care and design of my trees. I find this book a real must for anyone beyond the beginners stage.

This is probably not the best way to take one's first step into genetics, as far as the biological and technical nuts and bolts of the subject are concerned. Yet, if I were a professor, I'd make this a required reading to all students of genetics in order for them to be further introduced to the historical and ethical sides of the matter...
Starting with Mendel's biography and scientific breakthroughs, Tudge offers a guided tour through the early, pioneering days of modern biology, explains the very basics of Mendelian and molecular genetics, then swiftly moves on to discuss several important aspects, consequences and moral and practical responsibilities derived from our present advanced and advancing knowledge of biological heredity.
I think readers with no firm foundation of genetics and evolutionary theory wouldn't grasp the basics so easily from the quick overview by the author, agile and clear though it is. Any other biology textbook will obviously fill such a bill much better...
But the book's absolute forte lies both in the introductory historical perspective and in the following essays on wildlife conservation, evolutionary psychology, genetic bio-engineering and philosophy of science (better still, philosophy after the science!).
Tudge has drawn his own conclusions, and one may or may not agree with him in some respects, especially in his last chapter... But he treats many issues in a clear, informed and scientifically sensible way, and those are exactly the issues all too often hyped up or simplistically downplayed by the media and by columnists who babble on and on, all too often unaware of what exactly they're talking about, and thus unable to convey any meaningful insights to their audiences but doubts, diffidence or, even worse, passive indifference before something apparently, but mistakenly, beyond their grasp.
The principles that lie at the basis of some modern or future biotechnologies are very much understandable instead, and should belong to everyone who wants to form an educated opinion about what's going on...
A book for the novice to learn a little bit more, and for everyone to ponder. Even the ones who think they already know better...
After a defence of Mendel and his contribution to biology, Tudge reviews what genes are and how they function. This in-depth overview is one of the best summations of genetic processes in print. This chapter alone is worth purchasing the book. Tudge traces the roles of DNA, RNA, the amino acids and proteins. He shows how even minuscule changes in any step in the sequence can lead to ineffective proteins. Such changes can be implemented in the development of the organism [or merely part of it] rendering it unfit to survive in its existing environment. Such change can also make the individual more fit if that environment is undergoing change. He reviews the history of discoveries concerning chromosomes, DNA [first called nuclein], enzymes and proteins. He reminds us that many of these finds were made while Mendel's work had sunk from sight. Tudge's list of the researchers involved and the dates of their discoveries is revealing for those not well-grounded in the history of biology. He shows how the many threads were brought together many years later.
Tudge addresses how the genetic ratios imply regular laws of inheritance. Tudge stresses the revolutionary aspect of this discovery and how it changed science's view of life. He notes how Mendelian genetics seemed to refute Darwin for some years. When these apparent discrepancies were later reconciled and molecular genetics arose as the science binding the two theories, limitless opportunities arose. Revelation of the DNA structure showed how genes could be identified and later used to understand their relation to the whole organism.
Tudge follows through with what has been achieved in genetic research and speculates on what the future might hold. He pulls no punches in his speculations and readers will be confronted with myriad possibilities. These shouldn't be discounted nor blithely cast aside as distasteful. His proposals are realistic and based on strong science.
This book should stand as Tudge's finest effort. He's written many books on science, with some focus on human evolution. Standing as a pinnacle among his publications, readers are urged to take up this volume intending to give it a careful read. His Epilogue carefully reviews the many ethical questions that arise from the new power that genetics has placed in our hands. He reminds us of the pitfalls that have been encountered in the past and to prepare for these in decision-making. Public policies, which ultimately rest in your hands, he reminds us, must be formulated on a basis of clear understanding of what is involved.
This book provides an excellent starting point for building that knowledge base. He warns us against letting events overtake us. Read him to stay abreast of what is transpiring.

Co-authored by John Bierman and Colin Smith, FIRE IN THE NIGHT is the immensely readable life story of an incredibly complex man. In a nutshell, after several brief chapters on Wingate's early life, the narrative sequentially covers his postings in Palestine, Ethiopia and, finally, India/Burma, during which time (1936-1944) he rose in rank from Lieutenant to Major General. In the British Mandate of Palestine, Orde became an ardent Zionist while fighting Arab "gangs" with Special Night Squads, the armed detachments of British regulars and Jews which he himself brought into being. In Ethiopia, his was a key role in the British victorious military effort to drive the Italians from the country and return Haile Selassie to the thrown. In India, Wingate's ultimate triumph before an untimely death was to conceive, form, train and deploy the Third Indian Division, the "Chindits", as a Special Force to insert behind Japanese lines in Northern Burma to destroy the enemy's means of communication and supply.
To my mind, the strength of this book is that it gives the reader an excellent overview of Wingate the man and soldier without getting bogged down in an overabundance of detail. Certainly, the subject of Wingate's character, obsessions and eccentricities could fill volumes. He was admired and loved by the men he literally led into battle. (He drove them hard, but he drove himself even harder.) Conversely, he was loathed by many of his officer peers and superiors for his arrogance, outspokenness, rudeness and personal slovenliness. (He was on record as calling some of his more Blimpish superiors "military apes".) But, he also had his admirers in high places, most notably Winston Churchill and Lord Louis Mountbatten, the Supreme Commander of all allied forces in Southeast Asia.
Perhaps the most endearing of Wingate's traits were his eccentricities. For example, he carried a wind-up alarm clock on his person because he considered watches unreliable. And then there was his attitude to personal nudity best illustrated by an incident during the wide press acclaim following his first Chindit campaign. An Australian correspondent invited to the general's hotel room in Delhi wrote:
"I found him sitting naked on his bed, eyes buried deep in a book. He hardly glanced up as I entered and rather gruffly asked what I wanted. ... He wasn't interested in me or my requirements, but seemed most excited about the book he was reading ... a critical commentary of Emily Bronte and her work."
Can you imagine those media hogs of the Second World War - Patton, Montgomery and MacArthur - doing that?
