There is space for 35 addresses per alphabet with plenty of room to enter name, address, phone, fax, and e-mail. The paper is of very good quality and so is the binding (so far). I look forward to using mine which was a present and I would most likely give this to someone as a birthday or anniversary present as well.

I know the beauty of the land and the feeling of a line tighten under a heavy fish, Everything is so real, from the sound of the water and the singing of a reel being stripped of its line down to the irritating buzzing of the bugs. He speaks of the friendships on the river so accurately one knows it is not fiction.
A wonderful read that I tore through and will sit down again to read it again to savour anything I may have missed.
My only regret is there were only 5 stars to give it.

Contains sound sensible advice, adopts gentle training methods ... with interesting chapters on dog nutrition and medication/inoculations that take an alternative (holistic?) approach ... worth considering ...
Oh ... and don't let the number '25' fool you ... the author covers almost all the issues commonly faced by dog owners everywhere ...
This book is very clearly written, well organinsed and makes for easy reading ... useful for all dog owners ... very good for first time dog owners ...

and start putting its commonsense advice into practice.
Of all the instructional books I've read in ANY category (and
I say this as a professional writer myself), this one stands
out for its clarity, sense of humor, and easy readability.
However, for the next edition, let there be more diagrams!
In spite of the authors' brilliant description of the swing -- the
best I have read yet -- I wish they'd have included a diagram
of a solid take-away, my own personal golf bugaboo.
(Perhaps the authors assume we already know how to do it.)
All the same, for a relatively small cash outlay you can't beat
this book.
But you will beat your friends.
solid golf book if you actually follow the direction they provide.....
In addition to the course management stuff, there is also good advise on working the ball and some basic mechanics for good putting, chipping and pitching. This book combined with Bob Rotella's Golf Is Not A Game Of Perfect really helped me to lower my scores.
If you hit it well on the range but always seem to have a few big numbers that wreck your score, this book and Dr. Bob's will definitely help you. I also read and am a big fan of the Pelz putting and short game books as well as Hogan's 5 essentials for the full swing. And of course what library would be complete without Harvey Penick's Little Red Book.
Also, not to ramble, but for general golf fun I like Bill Murrey's Cinderella Story and John Feinstein's A Good Walk Spoiled.
I got the Tiger book and wasn't overly impressed.

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.
