" ... many eminent scholars, endowed with great geometric talent, make a point of never disclosing the simple and direct ideas that guided them, subordinating their elegant results to abstract general theories which often have no application outside the particular case in question. Geometry was becoming a study of algebraic, differential or partial differential equations, thus losing all the charm that comes from its being an art." H. Lebesgue, Ler;ons sur les Constructions Geometriques, Gauthier Villars, Paris, 1949. This book is based on lecture courses given to final-year students at the Uni versity of Nottingham and to M.Sc. students at the University of the West Indies in an attempt to reverse the process of expurgation of the geometry component from the mathematics curricula of universities. This erosion is in sharp contrast to the situation in research mathematics, where the ideas and methods of geometry enjoy ever-increasing influence and importance. In the other direction, more modern ideas have made a forceful and beneficial impact on the geometry of the ancients in many areas. Thus trigonometry has vastly clarified our concept of angle, calculus has revolutionised the study of plane curves, and group theory has become the language of symmetry.

In mathematics we are interested in why a particular formula is true. Intuition and statistical evidence are insufficient, so we need to construct a formal logical proof. The purpose of this book is to describe why such proofs are important, what they are made of, how to recognize valid ones, how to distinguish different kinds, and how to construct them. This book is written for 1st year students with no previous experience of formulating proofs. Dave Johnson has drawn from his considerable experience to provide a text that concentrates on the most important elements of the subject using clear, simple explanations that require no background knowledge of logic. It gives many useful examples and problems, many with fully-worked solutions at the end of the book. In addition to a comprehensive index, there is also a useful `Dramatis Personae` an index to the many symbols introduced in the text, most of which will be new to students and which will be used throughout their degree programme.

The main object of study for this book is geometry, with group theory providing an appropriate language in which to express geometrical ideas. Key features include: An overview of the preliminaries from group theory and geometry Coverage of the discrete subgroups of the Euclidean group A clear and complete derivation and classification of the 17 plane crystallographic groups Tessellations of various spaces (they are constructed, described and classified) A brief introduction to hyperbolic geometry. Each chapter contains a number of exercises, most with solutions, and suggestions for background, alternative and further reading. The author's accessible and down-to-earth approach make this an ideal introduction for readers in the second or third year of a mathematics undergraduate course. It is also recommended for mechanical engineers, architects, physicists and crystallographers needing an understanding of 3-dimensional geometry, symmetry and trigonometry.

Tenacious, novice banker, Rian Reston, rises from a broken family to be bilked out of an immense sum in a small Colorado mountain town. He''s fired. Without money, friends or family, he contemplates suicide. At the last moment, he gets menial work on a failing cattle ranch. While there, he meets his mentor, Reggie, who hires Rian. Unbeknownst to the two, the bank employing them is owned by Scaratucci, a mobster using it to launder money. While working at the bank, Rian meets tree-hugger Missy and her friend, Tablita, a Native American woman and US Senator. Meeting Missy changes everything Rian knows and feels about love.Then, a long nation-wide power outage hits America. It inspires Rian to seek a solution to the fragile bank payment system, Rian uncovers ancient deep layers of bank deception in plain sight, with bankers pretending to take in deposits they lend in their communities. Scaratucci''s bard-quoting hitman is turned loose when Rian learns how to prevent payment pandemonium in predatory banks, as happened in 2008. To carry it out, Rian and Missy start a political movement.Tablita presents Rian''s idea to Congress and his testimony before them, raises his stature in the media''s eyes. Following his idea, the legislation threatens to end the mafia''s money laundering and banks harming people. Congress and the vacillating President are caught up in the public''s protests who are mad as hell. Public protests demand Congress pass the proposed Public Payment Act, creating a secure payment system without private banks. That spark turns Rian''s grassroots movement into a raging prairie fire that sweeps the county.
