Sextants at Greenwich consists of two main sections: The introductory chapters and the catalogue of navigating instruments of the National Maritime Museum. The first section gives a general overview of the history of celestial navigation with an emphasis on the instruments that were developed and used for that purpose, between about 1450 and the 1970s. The instruments in the catalogue form the main thread in these chapters. The catalogue consists of 347 entries of instruments for celestial navigation, the octants, sextants and related instruments preserved in the National Maritime Museum. Each entry includes the place of the object's origin, its maker, the object's date, inscriptions (by the maker and/or relating to an owner), the graduated scale, the instrument's dimensions and a general description that includes details such as used materials and detached parts. Finally the object's provenance (previous owners and/or users) and references to literature on its history and handling are given.

This book describes in detail the various theories on the shape of the Earth from classical antiquity to the present day and examines how measurements of its form and dimensions have evolved throughout this period. The origins of the notion of the sphericity of the Earth are explained, dating back to Eratosthenes and beyond, and detailed attention is paid to the struggle to establish key discoveries as part of the cultural heritage of humanity. In this context, the roles played by the Catholic Church and the philosophers of the Middle Ages are scrutinized. Later contributions by such luminaries as Richer, Newton, Clairaut, Maupertuis, and Delambre are thoroughly reviewed, with exploration of...
A timely examination of the ways in which sixteenth-century understandings of the world were framed by classical theory.
By examining in detail the material life of pre-industrial peoples around the world, Fernand Braudel significantly changed the way historians view their subject. Originally published in the early 1980s, Civilization traces the social and economic history of the world from the Middle Ages to the Industrial Revolution, although his primary focus is Europe. Braudel skims over politics, wars, etc., in favor of examining life at the grass roots: food, drink, clothing, housing, town markets, money, credit, technology, the growth of towns and cities, and more. Volume I describes food and drink, dress and housing, demography and family structure, energy and technology, money and credit, and the growth of towns.
A journey in the history of science across the shifting religious, epistemic, and technical practices on a remarkable sixteenth-century voyage.
This book presents a realistic and thoroughly spiritual outlook upon the entire created reality. It lets us envisage that various created entities are participant in a relationship with God that becomes increasingly one of an intimate personal quality; that is, a relationship of love. It thus invites discernment that the universal reality is valuable in its own right and not only as a good for the use of humanity. Drawing mainly upon Scripture, ancient writers (especially Maximus the Confessor), as well as contemporary natural sciences, this book encourages the reader to perceive human salvation not as a lifting of humanity out of creation, but as a transformation into God's presence in the midst of the wider created order. It shows that Christian faith at its best does not exclude the wider creation but provides us with insight and hope for a harmonious being-in-God that is inclusive of creation. It shows that Christian faith can be a resource that helps overcome the ecological crisis.
