Earth's Shape from Newton to Clairaut 1995


Banyak buku yang telah diterbitkan mengenai aspek sains dan sejarah pengkajian bentuk bumi. Tajuk ini menjadi tumpuan bidang geodesi (dan sebelumnya oleh ahli astronomi). Salah satu buku tersebut ialah The problem of the Earth's shape from Newton to Clairaut yang terbit pada 1995 tulisan John Greenberg. Buku diterbitkan oleh Cambridge University Press.



Earth's Shape from Newton to Clairaut

Deskripsi buku - source cambridge

This book investigates, through the problem of the Earth's shape, part of the development of post-Newtonian mechanics by the Parisian scientific community during the first half of the eighteenth century. In the Principia, Newton first raised the question of the Earth's shape. John Greenberg shows how continental scholars outside France influenced efforts in Paris to solve the problem, and he also demonstrates that Parisian scholars, including Bouguer and Fontaine, did work that Alexis-Claude Clairaut used in developing his mature theory of the Earth's shape. The evolution of Parisian mechanics proved not to be the replacement of a Cartesian paradigm by a Newtonian one, a replacement that might be expected from Thomas Kuhn's formulations about scientific revolutions, but a complex process instead involving many areas of research and contributions of different kinds from the entire scientific world. Greenberg both explores the myriad of technical problems that underlie the historical development of part of post-Newtonian mechanics and embeds his technical discussion in a framework that involves social and institutional history, politics, and biography.

Digital Aerial Mapping Notes - Martin Vermeer 2018


Martin Vermeer lebih dikenali sebagai seorang ahli geodesi dan kebanyakan penerbitan beliau memang mengenai geodesi. Namun ketika mencari-cari penulisan beliau terjumpa pula satu nota kuliah mengenai fotogrametri. Beliau menghasilkan penerbitan "Digital aerial mapping - a hands-on course" pada April 2018.

Chapter 15 nota tersebut bertajuk "Datums in geodesy and photogrammetry" adalah suatu yang menarik untuk dibaca.

Berikut adalah petikan preface nota oleh Vermeer;

This book grew out of a series of lectures the first author, professor of geodesy at Aalto University’s Department of the Built Environment, held as a guest lecturer at Bahir Dar University’s Institute of Land Administration in Ethiopia. The intensive course, delivered over two weeks full time, was to give the students hands-on experience using digital aerial photogrammetry software in the service of mapping the country for economic development.
