This vividly illustrated history of the International Congress of Mathematicians- a meeting of mathematicians from around the world held roughly every four years- acts as a visual history of the 25 congresses held between 1897 and 2006, as well as a story of changes in the culture of mathematics over the past century. Because the congress is an int
This open access book on the history of the National Radio Astronomy Observatory covers the scientific discoveries and technical innovations of late 20th century radio astronomy with particular attention to the people and institutions involved. The authors have made extensive use of the NRAO Archives, which contain an unparalleled collection of documents pertaining to the history of radio astronomy, including the institutional records of NRAO as well as the personal papers of many of the pioneers of U.S. radio astronomy. Technical details and extensive citations to original sources are given in notes for the more technical readers, but are not required for an understanding of the body of the book. This book is intended for an audience ranging from interested lay readers to professional researchers studying the scientific, technical, political, and cultural development of a new science, and how it changed the course of 20th century astronomy.
This book describes the 1873 voyage of the British explorer Benjamin Leigh Smith, based on the diaries and photographs of Lieutenant Herbert C. Chermside, who joined the expedition of the seas around Svalbard. Chermside’s photographs, long believed lost, have recently been uncovered in Sweden and are being curated there by the Grenna Museum. The three unpublished diaries of Herbert Chermside were lent to the Scott Polar Research Institute in 1939 by Mrs. Benjamin Leigh Smith. For the first time, Chermside’s diaries are published in their entirety, with the original photographs shown alongside modern images of the same locations. This includes the first photographic record of the north coast of Svalbard, images that are today being used as comparative data for the study of climate change in the archipelago. The diaries have been fully transcribed and edited. Introductory chapters are included, written by specialists in the history of exploration, history of science, and the history of photography from Penn State University, the University of Gothenburg, and UiT, the Arctic University of Norway, as well as contributors from the UK and Germany. This volume is published in association with Grenna Museum, which will present Chermside’s photographs in a 2022 exhibit on Leigh Smith and A.E. Nordenskiold.
The aim of this book is to demonstrate to a wider audience, as well as to a more skilled audience, the many fascinating aspects of modern celestial mechanics. It sets out to do this without the use of mathematics. After giving the reader the technical tools needed for a basic understanding of the underlying physical phenomena (using only elementary mathematics), facts and figures are provided on historical events, modern discoveries and future applications. Contents are divided into major topics where the three "souls" of modern celestial mechanics (dynamical systems, Solar System and stellar systems, spaceflight dynamics) play a major role.

This flagship work charts a complete chronological log of orbital manned spaceflight. Included are the X-15 "astroflights" of the 1960s, and the two 1961 Mercury and Redstone missions which were non-orbital. There is an image depicting each manned spaceflight, and data boxes containing brief biographies of all the space travelers. The main text is a narrative of each mission, its highlights and accomplishments, including the strange facts and humorous stories connected to every mission. The resulting book is a handy reference to all manned spaceflights, the names of astronauts and cosmonauts who flew on each mission, their roles and accomplishments.
In its last decades, the apartheid regime was confronted with an existential threat. While internal resistance to the last whites-only government grew, mandatory international sanctions prohibited sales of strategic goods and arms to South Africa. To counter this, a global covert network of nearly fifty countries was built. In complete secrecy, allies in corporations, banks, governments and intelligence agencies across the world helped illegally supply guns and move cash in one of history's biggest money laundering schemes. Whistleblowers were assassinated and ordinary people suffered. Weaving together archival material, interviews and newly declassified documents, Apartheid Guns and Money exposes some of the darkest secrets of apartheid's economic crimes, their murderous consequences, and those who profited: heads of state, arms dealers, aristocrats, bankers, spies, journalists and secret lobbyists. These revelations, and the difficult questions they pose, will both allow and force the new South Africa to confront its past.
What happens when a seventeenth-century bad guy has twenty-first-century technology? An accident with an antigravity machine catapulted Peter Schock and Kate Dyer back to 1763. A bungled rescue attempt leaves Peter stranded in the eighteenth century while a terrifying villain, the Tar Man, takes his place and explodes onto twenty-first-century London. Concerned about the potentially catastrophic effects of time travel, the NASA scientists responsible for the situation question whether it is right to rescue Peter. Kate decides to take matters into her own hands, but things don't go as planned. Soon the physical effects of time travel begin to have a disturbing effect on her. Meanwhile, in our century, the Tar Man wreaks havoc in a city whose police force is powerless to stop him.Set against a backdrop of contemporary London and revolutionary France, The Time Thief is the sequel to the acclaimed The Time Travelers.
