The Story of Variable Stars is a book written by Leon Campbell that explores the fascinating world of variable stars. The book provides a comprehensive overview of these stars, which are stars that change in brightness over time. The author delves into the history of variable star research, from the early observations made by ancient astronomers to the modern-day techniques used by astrophysicists.Campbell also explores the different types of variable stars, including pulsating stars, eclipsing binaries, and cataclysmic variables. He explains the physics behind these phenomena and how they can be used to study the properties of stars and the universe as a whole.The book is written in a clear and accessible style, making it suitable for both amateur and professional astronomers. It includes numerous illustrations and diagrams to help readers understand the concepts and phenomena discussed.Overall, The Story of Variable Stars is a fascinating and informative book that provides a comprehensive overview of this important area of astronomy. It is a must-read for anyone interested in the study of stars and the universe.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

This series of dialogues between the spiritual and the scientific is framed by Klein's deep knowledge of cell biology.

It was a time of destruction of lives and futures and of rebirth and rebuilding. In his lively style with a wide sweep of insights Peter Lindenfeld recounts his personal and often intimate experiences, a microcosm of life during a time spanning nearly a century. The seemingly stable atmosphere of his childhood in Vienna is destroyed by the Anschluss, the annexation of Austria by Nazi Germany. The forced exodus leads him to North America, first to Vancouver, then to New York and a life that melds his original culture with that of his new environment, creating a richness-in science and music, and in intellectual and political life-that transcends both.

My 'discovery' of the Polish School of philosophy of medicine stemmed from my studies in the genesis of Ludwik Fleck's epistemology. These studies, and my interest in the scientific roots of Fleck's epistemology were a nearly 'natural' result of my own biography: like Fleck I had been trained, an had worked as an immunologist, and had later switched to studies in the social history of medicine and biology. Moreover, it so happened that Fleck's book, Genesis and Development of a Scientific Fact -the description of a science as it is, not as it should be -was the first epistemological study in which I found echos of my experience in the laboratory. My interest in Fleck was also highlightened by the fact that in his works, and, as I discovered later, in the works of his predecessors of the Polish School of philosophy of medicine, was formulated the problem that had stimulated my interest in the history of medicine and biology, and is still central to my present investigations: the relationships between biological knowledge and clinical practice. The writing of the book was made possible through to the help of many colleagues and friends. The unfailing support for my research, whatever its subject might be, from my colleagues from Unit 158 of INSERM and in particular from its head Patrice Pinell, has made my study of the Polish School possible.

No Place to Fall is Victor Saunders' follow up to his Boardman Tasker Prize winning debut book Elusive Summits . Covering three expeditions in Nepal, the Karakoram and the Kumaon, each shares the exhilaration of attempting new alpine-style routes on terrifyingly committing mountains. In 1989 Victor Saunders and Steve Sustad completed a difficult route on the West Face of Makalu II , only to be brought to a storm-bound halt above 7,000 metres while descending. Without food or bivouac gear, they endured a tortuous descent after a night in the open. Two years later the pair were with a small team in the Hunza valley exploring elusive access to a giant hidden pillar on the unvisited South-East Face of Ultar , one of the highest and most shapely of the world's unclimbed peaks. In 1992 Victor Saunders was part of a joint Indian-British team climbing various peaks in the Panch Chuli range. A happy and successful expedition narrowly avoided ending in tragedy when Stephen Venables broke both legs in a fall on the descent from Panch Chuli V and Chris Bonington survived another fall going to his aid. The dramatic evacuation of Venables, in which the author took a major part, forms an exciting climax to a story of cutting-edge, alpine-style climbing in the world's highest mountains. No Place to Fall offers enviable mountain exploration, enriched by sharing the lives of the mountain peoples along the way. Victor Saunders casts a perceptive, if bemused, eye over his fellow climbers and reflects on the calculation of risk that drives them back year after year to chance their lives in high places.
