Book excerpt: Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1890-1891, Vol. 20 The method of staining nerve-fibres which I have employed consists of a modified use of Weigert's haematoxylin. The tissue which was stained by this method was for the most part killed in hot water, although I have also successfully stained nerve-fibres which were killed in chromic acid and Kleinenberg's picro-sulphuric acid. Sections of the optic nerve which had been mounted on the slide and carried into water were treated for about half a minute with an aqueous solution of potassic hydrate 11670. They were then thoroughly rinsed in distilled water and transferred to Weigert's haematoxylin. Here they remained for about three hours at a temperature of 50 C. They were then rinsed again in distilled water, carried through the grades of alcohol, and after being dehydrated with alcohol of about they were cleared in turpentine and mounted in benzole balsam. Each nerve-fibre when so treated had a distinct blue-gray outline. The sections do not over stain even when they are kept in the dye for a prolonged period, and there is of course no subsequent decoloring. This method yields fair results when applied to nerves from any part of the lobster's body, but it is especially successful in treating that portion of the optic nerve which intervenes between the retina and the optic ganglion.

Book excerpt: Excerpt from Bulletin of the Museum of Comparative Zoölogy at Harvard College, in Cambridge, 1898-1899, Vol. 32 Clusters of nematocysts are found in the numerous wart-like pro tuberances (figs. 24 and 29, Plates X. And XI.) which are thickly scattered over the exumbrella surface of the disk, the palps, and the tentacles. These protuberances are thickly clustered near the centre of the disk, where they appear as little hemispherical projections above the general surface near the outer edges of the disk, however, they are elongate in' shape, and at the extreme edge they are again hemispherical (see Figs. 19, 26, 28, and If a weak solution of picric acid in 50% alcohol is allowed to permeate the sea water in which the medusa is living the nematocysts are exploded with great energy. Ordinarily they then present the appearance shown in Figure 21, Plate IX., but occasionally one finds one resembling that shown in Figure 22, where the main shaft of the thread is tightly coiled in a right-handed helix, and a small ellipsoidal mass of protoplasm (p) is borne upon the free extremity. It is very difficult to imagine how such a thread could be turned outward in the ordinary manner, and it is probable that the extreme stimulation caused by the picric acid produced an abnormal discharge of the nematocysts. The nematocysts which exhibited this peculiar structure were invariably immature in development, and were only about one tenth as numerous as the ordinary normal ones.

Book excerpt: Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1904-1906, Vol. 46 Less a stranger to fame than Cecco is Giovanni Boccaccio, prince of story-tellers (l3l3 - l375), one of whose early amusements consisted in gathering fossil shells near his home in the Valdelsa, hard by Florence. Unusually intelligent and well educated himself, he deplored the pre vailing ignorance of his age, and aided largely in reviving the study of classic literature in Italy. Amongst his more serious Latin works is a Geographical Dictionary,1 a laborious but indiscriminating compilation.

Download or read book Consilience written by E. O. Wilson and published by Vintage. This book was released on 2014-11-26 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: NATIONAL BESTSELLER • "A dazzling journey across the sciences and humanities in search of deep laws to unite them." —The Wall Street Journal One of our greatest scientists—and the winner of two Pulitzer Prizes for On Human Nature and The Ants—gives us a work of visionary importance that may be the crowning achievement of his career. In Consilience (a word that originally meant "jumping together"), Edward O. Wilson renews the Enlightenment's search for a unified theory of knowledge in disciplines that range from physics to biology, the social sciences and the humanities. Using the natural sciences as his model, Wilson forges dramatic links between fields. He explores the chemistry of the mind and the genetic bases of culture. He postulates the biological principles underlying works of art from cave-drawings to Lolita. Presenting the latest findings in prose of wonderful clarity and oratorical eloquence, and synthesizing it into a dazzling whole, Consilience is science in the path-clearing traditions of Newton, Einstein, and Richard Feynman.

Download or read book Passionate Curiosities written by Lauren Elizabeth Talalay and published by Kelsey Museum Publications. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Passionate Curiosities explores the collections held in the University of Michigan's Kelsey Museum of Archaeology through the lens of the people whose intellectual interests, financial backing, and social networks brought artifacts to Ann Arbor from the 1880s to the 1990s. Through purchases and expeditions, these individuals shaped the Museum's internationally recognized antiquities from the ancient civilizations of Greece, Rome, North Africa, Egypt, and the Near East, extensive photographic documentation of these regions from the early 1900s, and significant assemblages of early Christian and Islamic visual culture. An intriguing array of personalities--from archaeologists, missionaries, and diplomats to industrialists, bankrollers, and inventors--weave through these pages. They include Ernst Herzfeld, the eminent Orientalist who helped forge antiquities legislation in Iran; Luigi Cesnola, the rapacious harvester of Cypriot sites; Esther Van Deman, the pioneering feminist and scholar of Roman construction techniques; and Samuel Goudsmit, the renowned nuclear physicist and avid Egyptologist. World-famous dealers who established standards in antiquities connoisseurship likewise populate these sagas. Readers will encounter Edgar J. Banks, a swashbuckling purveyor of Mesopotamian antiquities and entrepreneur of biblical documentary films; Maurice Nahman, the "lion of Cairo"; and the colorful members of the Tano dealer dynasty in Egypt. This copiously illustrated book will interest general readers as well as scholars curious about the holdings of the Kelsey, early collectors and dealers, and the history of museums.
Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by OUP Oxford. This book was released on 2010-01-08 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Download or read book Trust in Numbers written by Theodore M. Porter and published by Princeton University Press. This book was released on 2020-08-18 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: A foundational work on historical and social studies of quantification What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy.

Download or read book Invention of Hysteria written by Georges Didi-Huberman and published by MIT Press. This book was released on 2004-09-17 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first English-language publication of a classic French book on the relationship between the development of photography and of the medical category of hysteria. In this classic of French cultural studies, Georges Didi-Huberman traces the intimate and reciprocal relationship between the disciplines of psychiatry and photography in the late nineteenth century. Focusing on the immense photographic output of the Salpetriere hospital, the notorious Parisian asylum for insane and incurable women, Didi-Huberman shows the crucial role played by photography in the invention of the category of hysteria. Under the direction of the medical teacher and clinician Jean-Martin Charcot, the inmates of Salpetriere identified as hysterics were methodically photographed, providing skeptical colleagues with visual proof of hysteria's specific form. These images, many of which appear in this book, provided the materials for the multivolume album Iconographie photographique de la Salpetriere. As Didi-Huberman shows, these photographs were far from simply objective documentation. The subjects were required to portray their hysterical "type"—they performed their own hysteria. Bribed by the special status they enjoyed in the purgatory of experimentation and threatened with transfer back to the inferno of the incurables, the women patiently posed for the photographs and submitted to presentations of hysterical attacks before the crowds that gathered for Charcot's "Tuesday Lectures." Charcot did not stop at voyeuristic observation. Through techniques such as hypnosis, electroshock therapy, and genital manipulation, he instigated the hysterical symptoms in his patients, eventually giving rise to hatred and resistance on their part. Didi-Huberman follows this path from complicity to antipathy in one of Charcot's favorite "cases," that of Augustine, whose image crops up again and again in the Iconographie. Augustine's virtuosic performance of hysteria ultimately became one of self-sacrifice, seen in pictures of ecstasy, crucifixion, and silent cries.
Download or read book Painted Love written by Hollis Clayson and published by Getty Publications. This book was released on 2003-10-30 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this engrossing book, Hollis Clayson provides the first description and analysis of French artistic interest in women prostitutes, examining how the subject was treated in the art of the 1870s and 1880s by such avant-garde painters as Cézanne, Degas, Manet, and Renoir, as well as by the academic and low-brow painters who were their contemporaries. Clayson not only illuminates the imagery of prostitution-with its contradictory connotations of disgust and fascination-but also tackles the issues and problems relevant to women and men in a patriarchal society. She discusses the conspicuous sexual commerce during this era and the resulting public panic about the deterioration of social life and civilized mores. She describes the system that evolved out of regulating prostitutes and the subsequent rise of clandestine prostitutes who escaped police regulation and who were condemned both for blurring social boundaries and for spreading sexual licentiousness among their moral and social superiors. Clayson argues that the subject of covert prostitution was especially attractive to vanguard painters because it exemplified the commercialization and the ambiguity of modern life.

Download or read book Complexity written by M. Mitchell Waldrop and published by Open Road Media. This book was released on 2019-10-01 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: “If you liked Chaos, you’ll love Complexity. Waldrop creates the most exciting intellectual adventure story of the year” (The Washington Post). In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell—and what the origin of life some four billion years ago can tell us about the process of technological innovation today. This book is their story—the story of how they have tried to forge what they like to call the science of the twenty-first century. “Lucidly shows physicists, biologists, computer scientists and economists swapping metaphors and reveling in the sense that epochal discoveries are just around the corner . . . [Waldrop] has a special talent for relaying the exhilaration of moments of intellectual insight.” —The New York Times Book Review “Where I enjoyed the book was when it dove into the actual question of complexity, talking about complex systems in economics, biology, genetics, computer modeling, and so on. Snippets of rare beauty here and there almost took your breath away.” —Medium “[Waldrop] provides a good grounding of what may indeed be the first flowering of a new science.” —Publishers Weekly
