The closed orbits of three-dimensional flows form knots and links. This book develops the tools - template theory and symbolic dynamics - needed for studying knotted orbits. This theory is applied to the problems of understanding local and global bifurcations, as well as the embedding data of orbits in Morse-smale, Smale, and integrable Hamiltonian flows. The necesssary background theory is sketched; however, some familiarity with low-dimensional topology and differential equations is assumed.

"In Search of a Perfect World" examines the basic questions of human life on Earth: Who are we? Where did we come from? Why are we here? And where are we going? In attempting to answer these questions, humans have formed religious, social and political groups and launched wars to remove impediments to their visions of a more-perfect world. Intentional or utopian communities have been similarly inspired. Throughout the world, many cultures have maintained a belief that the world was once a better, more harmonious place and -and will be again, after some form of cataclysm and the arrival of a savior or redeemer. This phenomenon, in some societies, is known as millennialism.
