Opis: Creating Symmetry - Frank Farris

This lavishly illustrated book provides a hands-on, step-by-step introduction to the intriguing mathematics of symmetry. Instead of breaking up patterns into blocks--a sort of potato-stamp method--Frank Farris offers a completely new waveform approach that enables you to create an endless variety of rosettes, friezes, and wallpaper patterns: dazzling art images where the beauty of nature meets the precision of mathematics. Featuring more than 100 stunning color illustrations and requiring only a modest background in math, Creating Symmetry begins by addressing the enigma of a simple curve, whose curious symmetry seems unexplained by its formula. Farris describes how complex numbers unlock the mystery, and how they lead to the next steps on an engaging path to constructing waveforms. He explains how to devise waveforms for each of the 17 possible wallpaper types, and then guides you through a host of other fascinating topics in symmetry, such as color-reversing patterns, three-color patterns, polyhedral symmetry, and hyperbolic symmetry. Along the way, Farris demonstrates how to marry waveforms with photographic images to construct beautiful symmetry patterns as he gradually familiarizes you with more advanced mathematics, including group theory, functional analysis, and partial differential equations. As you progress through the book, you'll learn how to create breathtaking art images of your own. Fun, accessible, and challenging, Creating Symmetry features numerous examples and exercises throughout, as well as engaging discussions of the history behind the mathematics presented in the book.Preface vii 1 Going in Circles 1 2 Complex Numbers and Rotations 5 3 Symmetry of the Mystery Curve 11 4 Mathematical Structures and Symmetry: Groups, Vector Spaces, and More 17 5 Fourier Series: Superpositions of Waves 24 6 Beyond Curves: Plane Functions 34 7 Rosettes as Plane Functions 40 8 Frieze Functions (from Rosettes!) 50 9 Making Waves 60 10 PlaneWave Packets for 3-Fold Symmetry 66 11 Waves, Mirrors, and 3-Fold Symmetry 74 12 Wallpaper Groups and 3-Fold Symmetry 81 13 ForbiddenWallpaper Symmetry: 5-Fold Rotation 88 14 Beyond 3-Fold Symmetry: Lattices, Dual Lattices, andWaves 93 15 Wallpaper with a Square Lattice 97 16 Wallpaper with a Rhombic Lattice 104 17 Wallpaper with a Generic Lattice 109 18 Wallpaper with a Rectangular Lattice 112 19 Color-ReversingWallpaper Functions 120 20 Color-Turning Wallpaper Functions 131 21 The Point Group and Counting the 17 141 22 Local Symmetry in Wallpaper and Rings of Integers 157 23 More about Friezes 168 24 Polyhedral Symmetry (in the Plane?) 172 25 HyperbolicWallpaper 189 26 Morphing Friezes and Mathematical Art 200 27 Epilog 206 A Cell Diagrams for the 17 Wallpaper Groups 209 B Recipes forWallpaper Functions 211 C The 46 Color-ReversingWallpaper Types 215 Bibliography 227 Index 229
