The title of this book is derived from a graduate course in which Professor Egon Orowan presented to M.I.T. students a clear and simple picture of the basic concepts in crystal plasticity and the mechanics of fracture of materials. Since the publication of his pioneering papers on dislocations and atomic mechanisms of fracture in the early 1930's,Professor Orowan has been one of the principal contributors to the field of physics of plasticity and strength. During the past 10 to 15 years, (...) the perfection of many direct experimental methods has caused a great increase of activity in the elucidation of the effects of dislocations on mechanical and physical properties. Equally intensive activity is taking place in the field of physics and mechanics of fracture processes. Professor Ali Argon felt that the retirement of Professor Orowan from the M.I.T. faculty was an appropriate occasion to take stock of the developments in the immediate past and to produce a needed synthesis of this technologically important field. For this purpose he invited 37 of the world's leading figures in the field to contribute theoretical papers of original work. The 17 papers on the Physics of Plasticity fall into two categories: Individual Dislocations and Basic Deformation Mechanisms, and Hardening Mechanisms and Dislocation Dynamics. The 10 papers on the Physics of Strength concentrate on Cracks and Fracture, and Geology. (shrink)

As graduates embark on the next phase of their lives, what better way to get them accustomed to the rat race they are about to enter than by introducing them to the philosophy of Jean-Paul Sartre? Cleverly told through the story of a pair of rats trapped in the labyrinth of existence, this allegory humorously conveys the key ideas of Sartre's existential philosophy in graphic-novel form - accessible for students and readers of all ages."--Back cover.

Bertrand Russell’s trip to China (1920–21) led him to write numerous articles about China culminating in _The Problem of China_. This paper reconsiders _The Problem of China_ using Edward Said’s discussion of Orientalism and contextualizes it with Russell’s other published and unpublished writings on China and the reactions of his Chinese contemporaries. I argue that Russell’s views reflect his prior philosophy and Western influences more than an analysis of his trip and reveal that this was what his Western readers wanted. (...) Moreover, his reliance on the research of other scholars and popular writers was unusual, even at the time. He was an intellectually honest but relatively unqualified and imprecise interpreter, not a Said-style Orientalist. He recognized Orientalism, but was unable to avoid reproducing Orientalist stereotypes. These findings help us understand both how Russell processed foreign phenomena and the origins of Western perceptions of China in the 1920s. (shrink)

The discovery of the noble gases and their incorporation into the periodic system are examined in this paper. A chronology of experimental reports on argon and helium and the properties relevant to their nature and position in the periodic system is presented. Proposals on the nature of argon and helium that appeared in the aftermath of their discovery are examined in light of the various empirical and theoretical considerations that supported and contradicted them. ``The piece that would not (...) fit'' refers not only to argon, the element that at first seemed not to fit into the periodic system, but also to the piece or pieces of evidence that various researchers and observers were prepared to discard or discount in coming to terms with the newly discovered gases.

Rayleigh and Ramsay discovered the inert gas argon in the atmospheric air in 1895 using a carefully designed sequence of experiments guided by an informal statistical analysis of the resulting data. The primary objective of this article is to revisit this remarkable historical episode in order to make a case that the error‐statistical perspective can be used to bring out and systematize (not to reconstruct) these scientists' resourceful ways and strategies for detecting and eliminating error, as well as dealing (...) with Duhemian ambiguities and underdetermination problems as they arose in the context of their local research settings. *Received December 2009; revised January 2010. †To contact the author, please write to: Department of Economics, 3016 Pamplin Hall, Virginia Tech, Blacksburg, VA 24061; e‐mail: [email protected].

It is well-known to scholars that the simile of the wool spinner described in Verg. Aen. 8.407–413 reworks on a verbal level Ap. Rhod. Argon. 3.291–295. Comparing Verg. Aen. 8.410 and Ap. Rhod. Argon. 3.291, this paper aims to suggest that in Ap. Rhod. Argon. 3.291 Virgil read a different text from that generally accepted by modern editors.
