Historians of Technology have failed to include the larger contribution and influence of Ctesibius’ compressor-driven Hydraulis with its pneumatic pumps, keyboard, and organ pipes in the path of critical preparatory events leading up to the ‘Latent’ Industrial Revolution. One should also realize that Ctesibius had all the parts and sub-assemblies on hand to invent the first Steam Hydraulis or Calliope, as illustrated on the front book cover of this work. From the 'Fertile Crescent' of the Persian Empire to the Hellenistic Library of Alexandria, Vitruvius writing brought the Hydraulis to the Abbey of St. Gall in 1414 during the Renaissance. Its path then took it through Italy, Germany, and the Paris of Louis XIV along the Arch of Industrial Reawakening. This was the Hydraulis 2-millennium path from Antiquity to its return reigniting the 'Latent' Industrial Revolution.

Each volume of the Dictionary of World Biography contains 250 entries on the lives of the individuals who shaped their times and left their mark on world history. This is not a who's who. Instead, each entry provides an in-depth essay on the life and career of the individual concerned. Essays commence with a quick reference section that provides basic facts on the individual's life and achievements. The extended biography places the life and works of the individual within an historical context, and the summary at the end of each essay provides a synopsis of the individual's place in history. All entries conclude with a fully annotated bibliography.

The Second International Congress on Photosynthesis Research took place in Stresa, Italy during June 24-29, 1971; two centuries after the discovery of Photosynthesis by Joseph Priestley in 1971. This important anniversary was celebrated at the Congress by a learned account of Priestley's life and fundamental discoveries given by Professor Robin HILL, F. R. S. Professor HILL's lecture opens the first of the three volumes which contains the contributions presented at the Congress. The manuscripts have been distributed into three volumes. Volume I con tains contributions in the areas of primary reactions and electron transport; Volume II ion transport and photophosphorylation, and Volume III carbon assimilation, regulatory phenomena, developmental aspects, and from the two special sessions of the Congress devoted to evolution and photorespiration. It is realized that this division is necessarily somewhat arbitrary since many contributions relate to more than one of the above mentioned titles. However, the large number of contributions (over 3000 typed pages) made it impossible to publish the proceedings in less than three volumes. The printing of these volumes and the organization of the Congress were made possible by a contribution from the Consigio Nazionale delle Ricerche of Italy. The generous support of the Istituto Lombardo Acca demia di Scienze e Lettere to the publication of these proceedings is gratefully acknowledged. The editors wish to express their appreciation to all the scientists who contributed the results of the investigations, for their coopera tion; and to Drs.

Profiles the eminent 18th century natural philosopher Henry Cavendish, best known for his work in chemistry and physics and one of the most baffling personalities in the history of science. In these chapters we are introduced to the psychology of science and of scientists and we learn about Cavendish’s life and times. His personality is examined from two perspectives: one is that he had a less severe form of autism, as has been claimed; the other is that he was eccentric and a psychological disorder was absent. Henry Cavendish lived a life of science, possibly more completely than any other figure in the history of science: a wealthy aristocrat, he became a dedicated scientist. This study brings new information and a new perspective to our understanding of the man. The scientific and non-scientific sides of his life are brought closer together, as the author traces topics including his appearance, speech, wealth, religion and death as well as Cavendish’s life of natural philosophy where objectivity and accuracy, writing and recognition all played a part. The author traces aspects of Cavendish’s personality, views and interpretations of him, and explores notions of eccentricity and autism before detailing relevant aspects of the travels made by our subject. The author considers the question “How do we talk about Cavendish?” and provides a useful summary of Cavendish’s travels. This book will appeal to a wide audience, from those interested in 18th century history or history of science, to those interested in incidences of autism in prominent figures from history. This volume contains ample relevant illustrations, several interesting appendices and it includes a useful index and bibliography.

'I never knew air could be so interesting' Bill Bryson 'A wonderful lesson in how science works' Simon Singh, Daily Telegraph ____________________ We not only live in the air, we live because of it. At ground level air transforms miraculously; it wraps our planet in a blanket of warmth, while the outer layer of our atmosphere soaks up violent flares from the sun. And air is about much more than just breathing. At ground level air transforms miraculously into solid food, and without it every creature on earth would starve; it wraps our planet in a blanket of warmth; radio signals bounce off a floating mirror of metal in the air to travel round the world; and the outer layer of our atmosphere soaks up flares from the sun more violent than all the world's nuclear warheads put together. Gabrielle Walker traces a journey of groundbreaking scientific discovery, from the Italian Renaissance scientist Torricelli, disciple of Galileo, who realised that we live at the bottom of a dense ocean of air, to the West Virginian farmhand William Ferrel, who unlocked the secrets of the trade winds by making calculations with a pitchfork on the back of a barn door. Then there is the hapless 1920s inventor Thomas Midgley, who when trying to solve a refrigeration problem inadvertently created chemicals that punched a hole in the sky, and the extraordinary American discovery at the height of the Cold War that space itself is radioactive. ____________________ 'A blend of science writing and historical anecdote that is hard to fault ... Walker's account of half a dozen scholars and their inspired hunches, painstaking experiments, wrong turns and dazzling discoveries is like a good detective story' New Statesman

Through a collection of works from key thinkers in natural philosophy, the second edition of The Scientific Background to Modern Philosophy illuminates the central role scientific writing played in developing modern philosophical thought. This revised and expanded edition includes many new translations and incorporates works by foundational eighteenth- and nineteenth-century thinkers not in the first edition, including selections from works by Jean-Baptiste, le Rond d’Alembert, Denis Diderot, Émilie Du Châtelet, Jean-Jacques Rousseau, Joseph Priestley, Immanuel Kant, Carl Linnaeus, William Paley, and Charles Robert Darwin. These new additions provide students with a more comprehensive understanding of the scientific context in which the major philosophical works of the modern era were written and complement the selections from works by Nicolaus Copernicus, Francis Bacon, Galileo Galilei, René Descartes, Robert Boyle, Christiaan Huygens, and Isaac Newton that are retained from the first edition.
