This book is an elementary introduction to geometric topology and its applications to chemistry, molecular biology, and cosmology. It does not assume any mathematical or scientific background, sophistication, or even motivation to study mathematics. It is meant to be fun and engaging while drawing students in to learn about fundamental topological and geometric ideas. Though the book can be read and enjoyed by nonmathematicians, college students, or even eager high school students, it is intended to be used as an undergraduate textbook. The book is divided into three parts corresponding to the three areas referred to in the title. Part 1 develops techniques that enable two- and three-dimensional creatures to visualize possible shapes for their universe and to use topological and geometric properties to distinguish one such space from another. Part 2 is an introduction to knot theory with an emphasis on invariants. Part 3 presents applications of topology and geometry to molecular symmetries, DNA, and proteins. Each chapter ends with exercises that allow for better understanding of the material. The style of the book is informal and lively. Though all of the definitions and theorems are explicitly stated, they are given in an intuitive rather than a rigorous form, with several hundreds of figures illustrating the exposition. This allows students to develop intuition about topology and geometry without getting bogged down in technical details.

Knots are familiar objects. Yet the mathematical theory of knots quickly leads to deep results in topology and geometry. This work offers an introduction to this theory, starting with our understanding of knots. It presents the applications of knot theory to modern chemistry, biology and physics.

?? Giant molecules are important in our everyday life. But, as pointed out by the authors, they are also associated with a culture. What Bach did with the harpsichord, Kuhn and Flory did with polymers. We owe a lot of thanks to those who now make this music accessible ??Pierre-Gilles de GennesNobel Prize laureate in Physics(Foreword for the 1st Edition, March 1996)This book describes the basic facts, concepts and ideas of polymer physics in simple, yet scientifically accurate, terms. In both scientific and historic contexts, the book shows how the subject of polymers is fascinating, as it is behind most of the wonders of living cell machinery as well as most of the newly developed materials. No mathematics is used in the book beyond modest high school algebra and a bit of freshman calculus, yet very sophisticated concepts are introduced and explained, ranging from scaling and reptations to protein folding and evolution. The new edition includes an extended section on polymer preparation methods, discusses knots formed by molecular filaments, and presents new and updated materials on such contemporary topics as single molecule experiments with DNA or polymer properties of proteins and their roles in biological evolution.

Knot theory is a kind of geometry, and one whose appeal is very direct because the objects studied are perceivable and tangible in everyday physical space. It is a meeting ground of such diverse branches of mathematics as group theory, matrix theory, number theory, algebraic geometry, and differential geometry, to name some of the more prominent ones. It had its origins in the mathematical theory of electricity and in primitive atomic physics, and there are hints today of new applications in certain branches of chemistryJ The outlines of the modern topological theory were worked out by Dehn, Alexander, Reidemeister, and Seifert almost thirty years ago. As a subfield of topology, knot theory forms the core of a wide range of problems dealing with the position of one manifold imbedded within another. This book, which is an elaboration of a series of lectures given by Fox at Haverford College while a Philips Visitor there in the spring of 1956, is an attempt to make the subject accessible to everyone. Primarily it is a text book for a course at the junior-senior level, but we believe that it can be used with profit also by graduate students. Because the algebra required is not the familiar commutative algebra, a disproportionate amount of the book is given over to necessary algebraic preliminaries.

Explains the universal information code connecting every person, plant, animal, and mineral and its applications in science, health care, and cosmic unity • Examines research on consciousness, quantum physics, animal and plant intelligence, emotional fields, Kirlian photography, and the effects of thoughts, emotions, and music on water • Reveals the connections between the work of Ervin Laszlo on the Akashic field, Rupert Sheldrake on morphogenetic fields, Richard Gerber on vibrational medicine, and Masaru Emoto on the memory of water DNA dictates the physical features of an organism. But what dictates how something grows--from the division of cells in a human being to the fractal patterns of a crystal? Massimo Citro reveals that behind the complex world of Nature lies a basic code, a universal information field--also known as the Akashic field, which records all that was, is, and will be--that directs not only physical development and behavior but also energetic communication and interactions among all living and non-living things. The author examines research on consciousness, quantum physics, animal and plant intelligence, the power of intention, emotional fields, Kirlian photography, and the effects of thoughts, emotions, and music on water. Linking the work of Ervin Laszlo on the Akashic field, Rupert Sheldrake on morphogenetic fields, Richard Gerber on vibrational medicine, and Masaru Emoto on the memory of water, Citro shows how the universal information field connects every person, plant, animal, and mineral--a concept long known by shamans and expounded by perennial wisdom. Putting this science of the invisible to practical use, he explains his revolutionary system of vibrational medicine, known as TFF, which uses the information field to obtain the benefits of natural substances and medications in their “pure” informational form, offering side-effect-free remedies for health and well-being.

This book introduces the study of knots, providing insights into recent applications in DNA research and graph theory. It sets forth fundamental facts such as knot diagrams, braid representations, Seifert surfaces, tangles, and Alexander polynomials. It also covers more recent developments and special topics, such as chord diagrams and covering spaces. The author avoids advanced mathematical terminology and intricate techniques in algebraic topology and group theory. Numerous diagrams and exercises help readers understand and apply the theory. Each chapter includes a supplement with interesting historical and mathematical comments.

MATEMAX is a bilingual schoolbook of mathematical problems written with the premise that one of the fundamental ways of learning mathematics, in addition to being one of the goals of the subject, is to solve problems. The book is designed for children and young teens and aims to teach mathematics in an entertaining way. Problems are based on familiar everyday situations, and helpful hints guide students to develop strategies before diving into calculations, leading to practice in abstract thinking, an essential feature of mathematics. Presented in both English and Spanish it also provides equal access to students, parents and teachers with facility in either or both languages. An online supplement is available upon request at [email protected]. This companion book provides complete solutions, alternative methods and additional suggestions to complement the short answers contained in the book. In addition, while problems are arranged in the book as they appear naturally in life, the companion text connects the mathematical tools with standard curricula. Here is a sampling of those pages.

El libro está diseñado para niños y adolescentes y tiene como objetivo enseñar matemática de una manera entretenida. Los problemas se basan en situaciones cotidianas familiares, y sugerencias útiles guían a los estudiantes para desarrollar estrategias antes de sumergirse en los cálculos, lo que lleva a la práctica del pensamiento abstracto, una característica esencial de la matemática. Presentado tanto en inglés como en español, también proporciona un acceso igual a estudiantes, padres y maestros con facilidad en uno o ambos idiomas. Un suplemento en línea está disponible a pedido en [email protected]. Este libro acompañante proporciona soluciones completas, métodos alternativos y sugerencias adicionales para complementar las respuestas cortas contenidas en el libro. Además, mientras que los problemas están ubicados en el libro como aparecen naturalmente en la vida, el texto complementario conecta las herramientas matemáticas con los planes de estudio estándar.
