Our knowledge of abundances, in both stellar and interstellar contexts, comes almost enti rely from line analysis, as does a major fraction of our ability to model stellar atmospheres. As new facets of the universe become observable so the techniques of high reso lution spectroscopy are brought to bear, with great reward. Improved instruments, such as echelle spectrographs, employ ing detectors of high quantum efficiency, have revolutioned our ability to observe high quality line profiles, although until now this ability has been confined to the brightest stars. Fabry-Perot interferometers and their modern deriva tives are bringing new ranges of resolving power to studies of atomic and ionic interstellar lines, and of course radio techniques imply exceedingly high resolution for the cool interstellar medium of molecules and radicals. Telescopes in space are extending the spectral range of these types of observations. Already the Copernicus and IUE high resolution spectrographs have given us a tantalizing glimmer of what it will be like to obtain ultraviolet spectra with resolution and signal to noise ratio approaching those obtainable on the ground. Fairly soon Space Telescope will be producing high resolution spectroscopic data of unparal leled quali ty and distance range. As often happens in astro physics the challenge is now coming from the observers to the theorists to provide interpretational tools which are adequate to the state of the data.

Available in PDF, EPUB and Kindle. Book excerpt: As in the case of "The Bases of Design," to which this is intended to form a companion volume, the substance of the following chapters on Line and Form originally formed a series of lectures delivered to the students of the Manchester Municipal School of Art. There is no pretension to an exhaustive treatment of a subject it would be difficult enough to exhaust, and it is dealt with in a way intended to bear rather upon the practical work of an art school, and to be suggestive and helpful to those face to face with the current problems of drawing and design. These have been approached from a personal point of view, as the results of conclusions arrived at in the course of a busy working life which has left but few intervals for the elaboration of theories apart from practice, and such as they are, these papers are now offered to the wider circle of students and workers in the arts of design as from one of themselves. They were illustrated largely by means of rough sketching in line before my student audience, as well as by photographs and drawings. The rough diagrams have been re-drawn, and the other illustrations reproduced, so that both line and tone blocks are used, uniformity being sacrificed to fidelity. WALTER CRANE. Outline, one might say, is the Alpha and Omega of Art. It is the earliest mode of expression among primitive peoples, as it is with the individual child, and it has been cultivated for its power of characterization and expression, and as an ultimate test of draughtsmanship, by the most accomplished artists of all time. The old fanciful story of its origin in the work of a lover who traced in charcoal the boundary of the shadow of the head of his sweetheart as cast upon the wall by the sun, and thus obtained the first profile portrait, is probably more true in substance than in fact, but it certainly illustrates the function of outline as the definition of the boundaries of form. Silhouette As children we probably perceive forms in nature defined as flat shapes of colour relieved upon other colours, or flat fields of light on dark, as a white horse is defined upon the green grass of a field, or a black figure upon a background of snow. Definition of Boundaries To define the boundaries of such forms becomes the main object in early attempts at artistic expression. The attention is caught by the edges—the shape of the silhouette which remains the paramount means of distinction of form when details and secondary characteristics are lost; as the outlines of mountains remain, or are even more clearly seen, when distance subdues the details of their structure, and evening mists throw them into flat planes one behind the other, and leave nothing but the delicate lines of their edges to tell their character. We feel the beauty and simplicity of such effects in nature. We feel that the mind, through the eye resting upon these quiet planes and delicate lines, receives a sense of repose and poetic suggestion which is lost in the bright noontide, with all its wealth of glittering detail, sharp cut in light and shade. There is no doubt that this typical power of outline and the value of simplicity of mass were perceived by the ancients, notably the Ancient Egyptians and the Greeks, who both, in their own ways, in their art show a wonderful power of characterization by means of line and mass, and a delicate sense of the ornamental value and quality of line. Formation of Letters Regarding line—the use of outline from the point of view of its value as a means of definition of form and fact—its power is really only limited by the power of draughtsmanship at the command of the artist. From the archaic potters' primitive figures or the rudimentary attempts of children at human or animal forms up to the most refined outlines of a Greek vase-painter, or say the artist of the Dream of Poliphilus, the difference is one of degree.

Book excerpt: This volume of The Handbook of Research in Middle Level Education is a significant contribution to the literature on middle level schools because it is written specifically with policymakers in mind. Middle level scholars have illuminated the most important issues concerning the education of young adolescents of which policymakers must be knowledgeable. It is only by having informed policymakers that middle level schools can truly thrive and provide the kind of education that every young adolescent deserves. The future of our country depends on it.

Available in PDF, EPUB and Kindle. Book excerpt: Drawing on various perspectives and analysis, the Handbook problematizes Middle East politics through an interdisciplinary prism, seeking a melioristic account of the field. Thematically organized, the chapters address political, social, and historical questions by showcasing both theoretical and empirical insights, all of which are represented in a style that ease readers into sophisticated induction in the Middle East. It positions the didactic at the centre of inquiry. Contributions by forty-four scholars, both veterans and newcomers, rethink knowledge frames, conceptual categories, and fieldwork praxis. Substantive themes include secularity and religion, gender, democracy, authoritarianism, and new "borderline" politics of the Middle East. Like any field of knowledge, the Middle East is constituted by texts, authors, and readers, but also by the cultural, spatial, and temporal contexts within which diverse intellectual inflections help construct (write–speak) academic meaning, knowing, and practice. By denaturalizing notions of singularity of authorship or scholarship, the Handbook plants a dialogic interplay animated by multi-vocality, multi-modality, and multi-disciplinarity. Targeting graduate students and young scholars of political and social sciences, the Handbook is significant for understanding how the Middle East is written and re-written, read and re-read (epistemology, methodology), and for how it comes to exist (ontology).

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1996. The First World War was the single most important event of the twentieth century. This volume concentrates on non-U.S. aspects of the conflict. Organized alphabetically, its more than 600 detailed entries offer information and insight on such subjects as the causes of the conflict, major battles and campaigns, weapons systems (including military aviation, chemical warfare, the submarine, and the tank), and the terms of the peace. Some 350 biographies provide information on the roles played in the conflict by generals, admirals, and civilian leaders. There are also biographies of individuals who were shaped by the war, such as Charles De Gaulle, Adolf Hitler, Benito Mussolini, and Joseph Stalin; essays on each of the countries involved in the conflict; new appraisals of such subjects as military medicine and artillery tactics; and essays on such diverse subjects as art, literature, and music in the war. Each entry has references for additional reading, and a subject index provides easy access. The volume is an excellent reference source for scholar and neophyte alike.
