As a citizen sailor of the late 1960's I spent three eventful years aboard a US Navy destroyer, the USS Furse (DD-882) including intensive operations in Vietnam as well as in the Atlantic and Indian Oceans in over 150,000 Nautical miles at sea. Those three years stand out as the most intense and formative of my adult life. Among the events I witnessed were running aground, colliding with another ship, being hit by enemy fire, and a murder on board. But many everyday challenges and events loom equally large for what they taught me about myself and about human nature in our tightly packed and tight-knit shipboard community. Letters written home almost every day along with declassified logs from the ship provide a window into life aboard a Navy destroyer. Re-entry to civilian life at the height of the Vietnam war illuminates these turbulent times as well as what citizen soldiers/sailors faced in that era.
Entangled with anxiety? Twisted with trepidation? Contorted with conflicts? From snarls in the workplace to hitches on the homefront, most of us find ourselves shaking our heads thinking: Is there any way to untangle this mess I call life? Greg Willits, Catholic author, media trailblazer, husband, and father, has experienced his share of knots, and he's here to assure you that there's no tangle you can't undo provided you have the right tools. Greg becomes your friend and (sometimes hilarious) companion in this endeavor, sharing his own experiences and those of others, as well as Scripture and Catholic teaching, walking along side you as you begin to untie the knots in your life. Tied in Knots begins to pull the thread so that you: See the knots in your life maybe for the first time Uncover your joy where it is, or where it went Look at who you really are and how that reveals God s will Rediscover what you love and make the time to start doing it again Create a concrete plan (finally) for finding true joy and lasting peace
More recently, Khovanov introduced link homology as a generalization of the Jones polynomial to homology of chain complexes and Ozsvath and Szabo developed Heegaard-Floer homology, that lifts the Alexander polynomial. These two significantly different theories are closely related and the dependencies are the object of intensive study. These ideas mark the beginning of a new era in knot theory that includes relationships with four-dimensional problems and the creation of new forms of algebraic topology relevant to knot theory. The theory of skein modules is an older development also having its roots in Jones discovery. Another significant and related development is the theory of virtual knots originated independently by Kauffman and by Goussarov Polyak and Viro in the '90s. All these topics and their relationships are the subject of the survey papers in this book.

This book brings together twenty essays on diverse topics in the history and science of knots. It is divided into five parts, which deal respectively with knots in prehistory and antiquity, non-European traditions, working knots, the developing science of knots, and decorative and other aspects of knots.Its authors include archaeologists who write on knots found in digs of ancient sites (one describes the knots used by the recently discovered Ice Man); practical knotters who have studied the history and uses of knots at sea, for fishing and for various life support activities; a historian of lace; a computer scientist writing on computer classification of doilies; and mathematicians who describe the history of knot theories from the eighteenth century to the present day.In view of the explosion of mathematical theories of knots in the past decade, with consequential new and important scientific applications, this book is timely in setting down a brief, fragmentary history of mankind's oldest and most useful technical and decorative device — the knot.
