Paperback. Condizione: Very Good. Knowledge is a big subject, says Stuart Firestein, but ignorance is a bigger one. And it is ignorance--not knowledge--that is the true engine of science. Most of us have a false impression of science as a surefire, deliberate, step-by-step method for finding things out and getting things done. In fact, says Firestein, more often than not, science is like looking for a black cat in a dark room, and there may not be a cat in the room. The process is more hit-or-miss than you might imagine, with much stumbling and groping after phantoms. But it is exactly this "not knowing," this puzzling over thorny questions or inexplicable data, that gets researchers into the lab early and keeps them there late, the thing that propels them, the very driving force of science. Firestein shows how scientists use ignorance to program their work, to identify what should be done, what the next steps are, and where they should concentrate their energies. And he includes a catalog of how scientists use ignorance, consciously or unconsciously--a remarkable range of approaches that includes looking for connections to other research, revisiting apparently settled questions, using small questions to get at big ones, and tackling a problem simply out of curiosity. The book concludes with four case histories--in cognitive psychology, theoretical physics, astronomy, and neuroscience--that provide a feel for the nuts and bolts of ignorance, the day-to-day battle that goes on in scientific laboratories and in scientific minds with questions that range from the quotidian to the profound. Turning the conventional idea about science on its head, Ignorance opens a new window on the true nature of research. It is a must-read for anyone curious about science. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.

Paperback. Condizione: Very Good. Environmental science (ecology, conservation, and resource management) is an increasingly quantitative field. A well-trained ecologist now needs to evaluate evidence generated from complex quantitative methods, and to apply these methods in their own research. Yet the existing books and academic coursework are not adequately serving most of the potential audience - instead they cater to the specialists who wish to focus on either mathematical or statistical aspects, and overwhelmingly appeal to those who already have confidence in their quantitative skills. At the same time, many texts lack an explicit emphasis on the epistemology of quantitative techniques. That is, how do we gain understanding about the real world from models that are so vastly simplified? This accessible textbook introduces quantitative ecology in a manner that aims to confront these limitations and thereby appeal to a far wider audience. It presents material in an informal, approachable, and encouraging manner that welcomes readers with any degree of confidence and prior training. It covers foundational topics in both mathematical and statistical ecology before describing how to implement these concepts to choose, use, and analyse models, providing guidance and worked examples in both spreadsheet format and R. The emphasis throughout is on the skilful interpretation of models to answer questions about the natural world. Introduction to Quantitative Ecology is suitable for advanced undergraduate students and incoming graduate students, seeking to strengthen their understanding of quantitative methods and to apply them successfully to real world ecology, conservation, and resource management scenarios. The book has been read, but is in excellent condition. Pages are intact and not marred by notes or highlighting. The spine remains undamaged.

Soft cover. Condizione: New. iii, 53 pages : illustrations ; 28 cm. Contents: Abstract -- Introduction -- The Marias River Canyon geoecosystem. Geologic setting ; Geomorphology of the Marias River Canyon ; Climatic setting ; Flora and large vertebrate fauna ; Overview of regional prehistory ; Archaeological site context -- Late Holocene depositional environments of the Marias River Canyon. Marias River depositional environment ; Alluvial-fan depositional environment ; Hillslope depositional environment -- Archaeological materials and geologic context of the Goose Bill Site Complex (24CH887). Site description ; Archaeological materials and stratigraphic context -- Archaeological and geological materials from the Sparrowhawk Site (24CH301). Site setting ; Archaeological materials and their context ; Stratigraphic context and age -- Geoecology : plant communities and ungulate niches. Plant communities ; Use of plants by native Americans ; Relations between depositional units and plant communities ; Ungulate niches -- Geoecological implications for archaeology -- Conclusions. The Marias River canyon in north-central Montana served during late Holocene time as a locus of human activity in an ecologically and geologically dynamic landscape. This volume presents the results of interdisciplinary research, synergistically combining geologic, ecologic, and archaeologic approaches focused on examining the ways that Late Precontact peoples depended upon the animal (bison) and plant resources of a changing landscape subject to erosion and sediment transport as dominant surficial processes. Connections between erosion and deposition, plant community distribution, large mammal niches, and native peoples' place in the Marias River canyon geoecosystem, as well as the role of tributary-junction alluvial fans as repositories of archaeological materials and vertebrate faunal remains are emphasized.
