From the Delaware River to the shores of Lake Erie, Pennsylvania's diverse watery habitats are home to more than 200 species of aquatic plants. In Aquatic Plants of Pennsylvania: A Complete Reference Guide, botanists Timothy A. Block and Ann Fowler Rhoads have assembled the first identification guide specific to the Keystone State yet useful throughout the Mid Atlantic region. Organized and written in a way that will make information easily accessible to specialists and nonspecialists alike, the book highlights the diversity and vital ecological importance of this group of plants, providing photographs, illustrations, descriptions, and identification keys for all emergent, floating-leaved, and submergent aquatic plants found in the Commonwealth.

An introductory chapter on aquatic plant ecology covers topics such as evolution, form, and reproduction of aquatic plants, vegetation zones, types of aquatic ecosystems, and rare and endangered species. Information on invasive plants, such as Eurasian water-milfoil and curly pondweed, that threaten Pennsylvania's aquatic ecosystems will be especially useful to watershed organizations, citizen monitoring projects, lake managers, and natural resource agency personnel. An illustrated identification key guides the reader through a series of steps to properly identify a specimen based on its characteristics. Each of the more than 200 listings provides a plant's taxonomy, detailed description, distribution map, and expert botanical illustrations. Many also include color photographs of the plants in their natural habitats.

The Arch Lake human burial site, discovered in 1967 in eastern New Mexico, contains the third-oldest known remains in North America. Since its original excavation and removal to Eastern New Mexico University’s Blackwater Draw Museum, the 10,000 radiocarbon-year-old burial has been known only locally. In February 2000 an interdisciplinary team led by Douglas W. Owsley reexamined the osteology, geology, archaeology, and radiocarbon dating of the burial. In this first volume in Peopling of the Americas Publications—released by Texas A&M University Press for the Center for the Study of the First Americans—Arch Lake Woman presents the results of this recent analysis of the skeleton and site. In addition to color and black-and-white illustrations, Arch Lake Woman includes extensive tables describing the team’s discoveries and comparing their results with those of other ancient burials.

The great mathematician Archimedes, a Sicilian Greek whose machines defended Syracuse against the Romans during the Second Punic War, was killed by a Roman after the city fell, yet it is largely Roman sources, and Greek texts aimed at Roman audiences, that preserve the stories about him. Archimedes' story, Mary Jaeger argues, thus becomes a locus where writers explore the intersection of Greek and Roman culture, and as such it plays an important role in Roman self-definition. Jaeger uses the biography of Archimedes as a hermeneutic tool, providing insight into the construction of the traditional historical narrative about the Roman conquest of the Greek world and the Greek cultural invasion of Rome. By breaking down the narrative of Archimedes' life and examining how the various anecdotes that comprise it are embedded in their contexts, the book offers fresh readings of passages from both well-known and less-studied authors, including Polybius, Cicero, Livy, Vitruvius, Plutarch, Silius Italicus, Valerius Maximus, Johannes Tzetzes, and Petrarch. "Jaeger, in her meticulous and elegant study of different ancient accounts of his life and inventions...reveal more about how the Romans thought about their conquest of the Greek world than about 'science'." ---Helen King, Times Literary Supplement "An absolutely wonderful book on a truly original and important topic. As Jaeger explores neglected texts that together tell an important story about the Romans' views of empire and their relationship to Greek cultural accomplishments, so she has written an important new chapter in the history of science. A genuine pleasure to read, from first page to last." ---Andrew Feldherr, Associate Professor of Classics, Princeton University "This elegantly written and convincingly argued project analyzes Archimedes as a vehicle for reception of the Classics, as a figure for loss and recovery of cultural memory, and as a metaphorical representation of the development of Roman identity. Jaeger's fastening on the still relatively obscure figure of the greatest ancient mathematician as a way of understanding cultural liminality in the ancient world is nothing short of a stroke of genius." ---Christina S. Kraus, Professor and Chair of Classics, Yale University "Archimedes and the Roman Imagination forms a useful addition to our understanding of Roman culture as well as of the reception of science in antiquity. It will make a genuine contribution to the discipline, not only in terms of its original interpretative claims but also as a fascinating example of how we may follow the cultural reception of historical figures." ---Reviel Netz, Professor of Classics, Stanford University Cover art: Benjamin West.

Art Nature Dialogues offers interviews with artists working with, in, and around nature and the environment. The interviews explore art practices, ecological issues, and values as they pertain to the siting of works, the use of materials, and the ethics of artmaking. John K. Grande includes interviews with Hamish Fulton, David Nash, Bob Verschueren, herman de vries, Alan Sonfist, Nils-Udo, Michael Singer, Patrick Dougherty, Ursula von Rydingsvard, and others.

Part ethnography and part historical study, The Artificial Ear is based on interviews with researchers who were pivotal in the early development and implementation of the new technology necessary for cochlear implants. Through an analysis of the scientific and clinical literature, Stuart Blume reconstructs the history of artificial hearing from its conceptual origins in the 1930s, to the first attempt at cochlear implantation in Paris in the 1950s, and to the widespread clinical application of the "bionic ear" since the 1980s.

This book provides the historical background for a central issue in the history of science: the influence of artisans, craftsmen, and other practitioners on the emergent empirical methodologies that characterized the “new sciences” of the late sixteenth and seventeenth centuries. Long offers a coherent account and critical revision of the “Zilsel thesis,” an influential etiological narrative which argues that such craftsmen were instrumental in bringing about the “Scientific Revolution.”

Artisan/Practitioners reassesses the issue of artisanal influence from three different perspectives: the perceived relationships between art and nature; the Vitruvian architectural tradition with its appreciation of both theory and practice; and the development of “trading zones”—arenas in which artisans and learned men communicated in substantive ways. These complex social and intellectual developments, the book argues, underlay the development of the empirical sciences.

This volume provides new discussion and synthesis of a theory that encompasses broad developments in European history and study of the natural world. It will be a valuable resource for college-level teaching, and for scholars and others interested in the history of science, late medieval and early modern European history, and the Scientific Revolution.

This book offers an informed and revealing account of NASA’s involvement in the scientific understanding of the Earth’s atmosphere. Since the nineteenth century, scientists have attempted to understand the complex processes of the Earth’s atmosphere and the weather created within it. This effort has evolved with the development of new technologies—from the first instrument-equipped weather balloons to multibillion-dollar meteorological satellite and planetary science programs. Erik M. Conway chronicles the history of atmospheric science at NASA, tracing the story from its beginnings in 1958, the International Geophysical Year, through to the present, focusing on NASA’s programs and research in meteorology, stratospheric ozone depletion, and planetary climates and global warming. But the story is not only a scientific one. NASA’s researchers operated within an often politically contentious environment. Although environmental issues garnered strong public and political support in the 1970s, the following decades saw increased opposition to environmentalism as a threat to free market capitalism. Atmospheric Science at NASA critically examines this politically controversial science, dissecting the often convoluted roles, motives, and relationships of the various institutional actors involved—among them NASA, congressional appropriation committees, government weather and climate bureaus, and the military.
