Tierck Clafsen DeWitt and Descendants of His Son Luycas DeWitt


Book Description

The DeWitt genealogy is a fascinating study of 26 generations of the family from 1293 to the present. This work is the collaboration of descendants of the three children of Leucas, ninth child of Tierck Clafsen DeWitt. American Ambassador Lester DeWitt Ballor of UEL descent obtained a copy from The Royal Library of the Hague of Beschayving DerStad Dordrecht by Mattys Balen, Jans Zoon published in 1677. This information provided the first thirteen generations in Holland. He also received a 32-page copy of a lawsuit in 1684 by Jan DeWitt on behalf of his brother Tierck for rent owned by Pieter Janz, their sister Faelde's husband. The property was land inherited by Tierck from his father Nicholaas. It provided information on her mother Taetje Cornelisz, her father, brothers and their shipyard.







The Pursuit of Quantum Gravity


Book Description

1946 is the year Bryce DeWitt entered Harvard graduate school. Quantum Gravity was his goal and remained his goal throughout his lifetime until the very end. The pursuit of Quantum Gravity requires a profound understanding of Quantum Physics and Gravitation Physics. As G. A. Vilkovisky commented , "Quantum Gravity is a combination of two words, and one should know both. Bryce understood this as nobody else, and this wisdom is completely unknown to many authors of the flux of papers that we see nowadays." Distingished physicist Cecile DeWitt-Morette skillfully blends her personal and scientific account with a wealth of her late husband's often unpublished writings on the subject matter. This volume, through the perspective of the leading researcher on quantum gravity of his generation, will provide an invaluable source of reference for anyone working in the field.







Invading Paradise


Book Description

Invading Paradise: Esopus Settlers at War with Natives, 1659, 1663 reopens and redirects debate about causes of the two Esopus Wars in what are now Kingston and Hurley, New York. Historical studies are found inadequate to explain the conflict and its genocidal outcome. If causality is ever to be reliably decided, the principal actors in this colonial drama need study. Records of aboriginals are understandably scant, while those of settlers are full enough to give impressions of their motivations and attitudes to the frontier. This study is the first to introduce as individuals the main European immigrants involved in the wars. Were they prepared for what confronted them upon acquiring native agricultural lands? Readers are invited to consider exactly what happened to bring on violence.










Records of the Reformed Dutch Church in New Amsterdam and New York


Book Description

In scarcely 200 pages, Professor Kuhns has surveyed the factors that compelled roughly 100,000 emigrants from the Palatinate, Wurtenberg, Zweibrucken, and other principalities in southern Germany to settle in Pennsylvania between 1683 and 1776 and establish a new way of life in their adopted homeland. Most of these immigrants were farmers, and their customs and manners are recounted in an examination of housing, provisions, agricultural methods, superstitions, and so forth. There is a chapter on language, literature, and education and a separate appendix on German family names. Perhaps the most informative chapter in the book covers the extraordinarily diverse religious life of these Protestant Germans, which, while dominated by the Lutheran and Reformed churches, also accommodated Moravians, Mennonites, Brethren, Dunkards, Seventh-Day Baptists, Schwenckfelders, and others.




Supermanifolds


Book Description

This book presents a detailed exposition of the modern theory of supermanifolds, including a rigorous account of the super-analogs of all the basic structures of ordinary manifold theory. The exposition opens with the theory of analysis over supernumbers (Grassmann variables), Berezin integration, supervector spaces and the superdeterminant. This basic material is then applied to the theory of supermanifolds, with an account of the super-analog of Lie derivatives, connections, metrics, curvature, geodesics, Killing flows, conformal groups, etc. The book goes on to discuss the theory of super Lie groups, super Lie algebras, and invariant geometrical structures on coset spaces. Complete descriptions are given of all the simple super Lie groups. The final chapter contains an account of the Peierls bracket for superclassical dynamical systems, super Hilbert spaces, path integration for fermionic quantum systems, and simple models of Bose-Fermi supersymmetry. Many exercises are included to supplement the material in the text.
