Book Description
Cambridge is now world-famous as a centre of science, but it wasn't always so. Before the nineteenth century, the sciences were of little importance in the University of Cambridge. But that began to change in 1819 when two young Cambridge fellows took a geological fieldtrip to the Isle of Wight. Adam Sedgwick and John Stevens Henslow spent their days there exploring, unearthing dazzling fossils, dreaming up elaborate theories about the formation of the earth, and bemoaning the lack of serious science in their ancient university. As they threw themselves into the exciting new science of geology - conjuring millions of years of history from the evidence they found in the island's rocks - they also began to dream of a new scientific society for Cambridge. This society would bring together like-minded young men who wished to learn of the latest science from overseas, and would encourage original research in Cambridge. It would be, they wrote, a society "to keep alive the spirit of inquiry". Their vision was realised when they founded the Cambridge Philosophical Society later that same year. Its founders could not have imagined the impact the Cambridge Philosophical Society would have: it was responsible for the first publication of Charles Darwin's scientific writings, and hosted some of the most heated debates about evolutionary theory in the nineteenth century; it saw the first announcement of x-ray diffraction by a young Lawrence Bragg - a technique that would revolutionise the physical, chemical and life sciences; it published the first paper by C.T.R. Wilson on his cloud chamber - a device that opened up a previously-unimaginable world of sub-atomic particles. 200 years on from the Society's foundation, this book reflects on the achievements of Sedgwick, Henslow, their peers, and their successors. Susannah Gibson explains how Cambridge moved from what Sedgwick saw as a "death-like stagnation" (really little more than a provincial training school for Church of England clergy) to being a world-leader in the sciences. And she shows how science, once a peripheral activity undertaken for interest by a small number of wealthy gentlemen, has transformed into an enormously well-funded activity that can affect every aspect of our lives.

Book Description
Cyanotype is the most accessible and frequently used of all the alternative photographic processes. When utilized properly, it has the potential to rival other processes when it comes to detail and tonal range, but its Prussian blue color isn’t always suitable for the final photograph. Throughout history, cyanotype prints have been toned not only with various—and at times hazardous—chemicals but also with more natural ingredients like tea and coffee. Since the cyanotype itself is non-toxic, Cyanotype Toning will champion an innovative process, developed by the author, of toning cyanotypes with natural material. This process, which is easy and reliable, offers a much broader range of possible colors and even beautiful black and whites. Even duotone or tricolor prints can be attained. The book consists of two parts. Part One is a step-by-step how-to section including all the information that a student at any level needs to achieve a successfully toned print. Easy-to-understand background information is provided on how and why the process works so that readers can venture on their own into the world of natural colors. The first part also has a detailed section on all the factors that can influence the outcome, like paper choice, water quality, properties of the plants, temperature of the bath and the duration of the toning. Part Two is devoted to contemporary artists who have explored toning with botanicals and integrated the process into their creative practice. The book includes: A list of equipment and supplies needed. In depth information about useful plants and the specific properties that make them suitable for toning cyanotypes. Concise step-by-step instructions for printing cyanotypes successfully. A chart of more than 60 tested papers with recommendations on paper choice. Step-by-step generic instructions on toning with botanicals. Troubleshooting toning with botanicals. More detailed recipes for specific colors with information about the plants. Step-by-step instructions on how to print duotone and tricolor prints. A range of creative ideas on how to use the process in classrooms and with different age groups. A comprehensive list of more than 380 tested parts of plants and possible color outcomes. Using botanicals to tone cyanotypes broadens the color spectrum, enlarges creative possibilities and makes the cyanotype process even more versatile. The process is not cut and dried science but a limitless field for discovery and surprises. Cyanotype Toning provides accessible information and instructions for readers at all levels. It is comprehensive and explanatory, so that readers can expand on the subject on their own, as did the contemporary artists who share their experiences and the works they have created using this innovative toning process.

Book Description
Written by William Sheehan, a noted historian of astronomy, and Christopher J. Conselice, a professional astronomer specializing in galaxies in the early universe, this book tells the story of how astronomers have pieced together what is known about the vast and complicated systems of stars and dust known as galaxies. The first galaxies appeared as violently disturbed exotic objects when the Universe was only a few 100 million years old. From that tortured beginning, they have evolved though processes of accretion, merging and star formation into the majestic spirals and massive ellipticals that dominate our local part of the Universe. This of course includes the Milky Way, to which the Sun and Solar System belong; it is our galactic home, and the only galaxy we will ever know from the inside. Sheehan and Conselice show how astronomers’ understanding has grown from the early catalogs of Charles Messier and William Herschel; developed through the pioneering efforts of astronomers like E.E. Barnard, V.M. Slipher, Henrietta Leavitt, Edwin Hubble and W.W. Morgan; and finally is reaching fruition in cutting-edge research with state-of-the-art instruments such as the Hubble Space Telescope that can see back to nearly the beginning of the Universe. By combining archival research that reveals fascinating details about the personalities, rivalries and insights of the astronomers who created extragalactic astronomy with the latest data gleaned from a host of observa tions, the authors provide a view of galaxies – and their place in our understanding of the Universe – as they have never been seen before.

Book Description
In 1833 John Herschel sailed from London to Cape Town, southern Africa, to undertake (at his own expense) an astronomical exploration of the southern heavens, as well as a terrestrial exploration of the area around Cape Town. After his return to England in 1838, and as a result of his voyage, he was highly esteemed and became Britain's most recognized man of science. In 1847 his southern hemisphere astronomical observations were published as the Cape Results. The main argument of Ruskin's book is that Herschel's voyage and the publication of the Cape Results, in addition to their contemporary scientific importance, were also significant for nineteenth-century culture and politics. In this book it is demonstrated that the reason for Herschel's widespread cultural renown was the popular notion that his voyage to the Cape was a project aligned with the imperial ambitions of the British government. By leaving England for one of its colonies, and pursuing there a significant scientific project, Herschel was seen in the same light as other British men of science (like James Cook and Richard Lander) who had also undertaken voyages of exploration and discovery at the behest of their nation. It is then demonstrated that the production of the Cape Results, in part because of Herschel's status as Britain's scientific figurehead, was a significant political event. Herschel's decision to journey to the Cape for the purpose of surveying the southern heavens was of great significance to almost all of Britain and much of the continent. It is the purpose of this book to make a case for the scientific, cultural, and political significance of Herschel's Cape voyage and astronomical observations, as a means of demonstrating the relationship of scientific practice to broader aspects of imperial culture and politics in the nineteenth century.
