Reproduction of the original: The Spanish Tragedy by Thomas Kyd

Speculate This! is a concise, provocative manifesto advocating practices of "affirmative speculation" over and against contemporary forms of speculation that quantify and contain risk to generate financial profit for a privileged few. This latter mode of speculation is predatory and familiar, its fallout evident in ongoing environmental degradation, in restrictive legal claims on natural resources in distant lands, and in the foreclosures, evictions, and unemployment resulting from the financial collapse of 2007–08. While such exploitive speculation seeks to reduce uncertainty and pin down the future, the affirmative practices championed by the authors of Speculate This! engage uncertainty, contingency, and difference, and they multiply, rather than reduce, possible futures. In these affirmative practices, social relations and the creation of goods and knowledge are not driven by the desire for financial gain or professional status. Whether manifest in open-source software, eco-communes, global activist movements, community credit networks, or experimental art, speculative living affirms our commonality. As a collaborative work coauthored by a group of anonymous scholars, Speculate This! argues for and embodies affirmative speculation.

The second edition of Applied Structural and Mechanical Vibrations: Theory and Methods continues the first edition’s dual focus on the mathematical theory and the practical aspects of engineering vibrations measurement and analysis. This book emphasises the physical concepts, brings together theory and practice, and includes a number of worked-out examples of varying difficulty and an extensive list of references. What’s New in the Second Edition: Adds new material on response spectra Includes revised chapters on modal analysis and on probability and statistics Introduces new material on stochastic processes and random vibrations The book explores the theory and methods of engineering vibrations. By also addressing the measurement and analysis of vibrations in real-world applications, it provides and explains the fundamental concepts that form the common background of disciplines such as structural dynamics, mechanical, aerospace, automotive, earthquake, and civil engineering. Applied Structural and Mechanical Vibrations: Theory and Methods presents the material in order of increasing complexity. It introduces the simplest physical systems capable of vibratory motion in the fundamental chapters, and then moves on to a detailed study of the free and forced vibration response of more complex systems. It also explains some of the most important approximate methods and experimental techniques used to model and analyze these systems. With respect to the first edition, all the material has been revised and updated, making it a superb reference for advanced students and professionals working in the field.
