This remarkable history encompasses not only the achievements of the early inventors and astronomers but also the less frequently recounted stories of the instrument makers and of the actual instruments. A model of unsurpassed, comprehensive scholarship, this volume covers many fields, including professional and amateur astronomy. 196 black-and-white illustrations.

A foundational work on historical and social studies of quantification What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy.

The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

"Beginning in 1580, London companies sold water to consumers through a large network of wooden mains in the expanding metropolis. This new water industry flourished throughout the 1600s, eventually expanding to serve tens of thousands of homes. By the late eighteenth century, more than 80 percent of the city's houses had water connections-making London the best-served metropolis in the world while demonstrating that it was legally, commercially, and technologically possible to run an infrastructure network within the largest city on earth. Leslie Tomory shows how new technologies imported from the Continent, including waterwheel-driven piston pumps, spurred the rapid growth of London's water industry. The business was further sustained by an explosion in consumer demand. Meanwhile, several key local innovations reshaped the industry by enlarging the size of the supply network. By 1800, the success of London's water industry made it a model for other cities in Europe and beyond as they began to build their own water networks, and it inspired builders of other large-scale urban projects, including gas and sewage supply networks."--Provided by the publisher.
