Book excerpt: The scientific achievements and forgotten legacy of a major Austrian research institute, from its founding in 1902 to its wartime destruction in 1945. The Biologische Versuchsanstalt was founded in Vienna in 1902 with the explicit goal to foster the quantification, mathematization, and theory formation of the biological sciences. Three biologists from affluent Viennese Jewish families—Hans Przibram, Wilhelm Figdor, and Leopold von Portheim–founded, financed, and nurtured the institute, overseeing its development into one of the most advanced biological research institutes of the time. And yet today its accomplishments are nearly forgotten. In 1938, the founders and other members were denied access to the institute by the Nazis and were forced into exile or deported to concentration camps. The building itself was destroyed by fire in April 1945. This book rescues the legacy of the “Vivarium” (as the Institute was often called), describing both its scientific achievements and its place in history. The book covers the Viennese sociocultural context at the time of the Vivarium's founding, and the scientific zeitgeist that shaped its investigations. It discusses the institute's departments and their research topics, and describes two examples that had scientific and international ramifications: the early work of Karl von Frisch, who in 1973 won the Nobel Prize in Physiology or Medicine; and the connection to Cold Spring Harbor Laboratory in New York.

Available in PDF, EPUB and Kindle. Book excerpt: On Growth and Form is a scholarly work by D'Arcy Wentworth Thompson. Thompson was a Scottish biologist, mathematician, classics scholar and a pioneer of mathematical biology. Excerpt: "Of the chemistry of his day and generation, Kant declared that it was "a science, but not science,"—"eine Wissenschaft, aber nicht Wissenschaft"; for that the criterion of physical science lay in its relation to mathematics. And a hundred years later Du Bois Reymond, profound student of the many sciences on which physiology is based, recalled and reiterated the old saying, declaring that chemistry would only reach the rank of science, in the high and strict sense, when it should be found possible to explain chemical reactions in the light of their causal relation to the velocities, tensions and conditions of equilibrium of the component molecules; that, in short, the chemistry of the future must deal with molecular mechanics, by the methods and in the strict language of mathematics, as the astronomy of Newton and Laplace dealt with the stars in their courses. We know how great a step has been made towards this distant and once hopeless goal, as Kant defined it, since van't Hoff laid the firm foundations of a mathematical chemistry, and earned his proud epitaph, Physicam chemiae adiunxit."

Available in PDF, EPUB and Kindle. Book excerpt: A harrowing account of the profoundly consequential decisions American universities made about refugee scholars from Nazi-dominated Europe--a finalist for a 2020 National Jewish Book Award The United States’ role in saving Europe’s intellectual elite from the Nazis is often told as a tale of triumph, which in many ways it was. America welcomed Albert Einstein and Enrico Fermi, Hannah Arendt and Herbert Marcuse, Rudolf Carnap and Richard Courant, among hundreds of other physicists, philosophers, mathematicians, historians, chemists, and linguists who transformed the American academy. Yet for every scholar who survived and thrived, many, many more did not. To be hired by an American university, a refugee scholar had to be world-class and well connected, not too old and not too young, not too right and not too left, and, most important, not too Jewish. Those who were unable to flee were left to face the horrors of the Holocaust. In this rigorously researched book, Laurel Leff rescues from obscurity scholars who were deemed “not worth saving” and tells the riveting, full story of the hiring decisions universities made during the Nazi era.
Download or read book Entomology written by Cedric Gillot and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of writing this book was conceived when, in the late 1960s, I began teaching a senior undergraduate class in general entomology. I soon realized that there was no suitable text for the class I intended to give. The so-called "general" or "introductory" texts reflected the traditional taxonomic approach to entomology and contained relatively little information on the physiology and ecology of insects. This does not mean that there were no books containing such information. There were several, but these were so specialized and de tailed that their use in an introductory class was limited. I hold a strong belief that an undergraduate general entomology course should provide a balanced treatment of the subject. Thus, although some time should be devoted to taxonomy, including identification (best done in the laboratory, using primar ily material which students themselves have collected, supplemented with specimens from the general collection), appropriate time should be given also to discussion of the evolution, development, physiology, and ecology of in sects. In the latter category I include the interactions between insects and Man because it is important to stress that these interactions follow normal ecological principles. Naturally, the format of this book reflects this belief. The book has been arranged in four sections, each of which necessarily overlaps with the others.
Download or read book What Makes a Good Experiment written by Allan Franklin and published by University of Pittsburgh Press. This book was released on 2016-09-07 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: What makes a good experiment? Although experimental evidence plays an essential role in science, as Franklin argues, there is no algorithm or simple set of criteria for ranking or evaluating good experiments, and therefore no definitive answer to the question. Experiments can, in fact, be good in any number of ways: conceptually good, methodologically good, technically good, and pedagogically important. And perfection is not a requirement: even experiments with incorrect results can be good, though they must, he argues, be methodologically good, providing good reasons for belief in their results. Franklin revisits the same important question he posed in his 1981 article in the British Journal for the Philosophy of Science, when it was generally believed that the only significant role of experiment in science was to test theories. But experiments can actually play a lot of different roles in science—they can, for example, investigate a subject for which a theory does not exist, help to articulate an existing theory, call for a new theory, or correct incorrect or misinterpreted results. This book provides details of good experiments, with examples from physics and biology, illustrating the various ways they can be good and the different roles they can play.
Download or read book Invertebrate Biology written by P. Calow and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Courses on the invertebrates have two principal aims: (1) to introduce students to the diversity of animal life and (2) to make them aware that organisms are marvellously integrated systems with evolutionary pasts and ecological presents. This text is concerned exclusively with the second aim and assumes that the reader will already know something about the diversity and classification of invertebrates. Concepts of whole-organism function, metabolism and adaptation form the core of the subject-matter and this is also considered in an ecological setting. Hence, the approach is multi-disciplinary, drawing from principles normally restricted to comparative morphology and physiology, ecology and evolutionary biology. Invertebrate courses, as with all others in a science curriculum, also have another aim - to make students aware of the general methods of science. And these I take to be associated with the so-calledhypothetico deductive programme. Here, therefore, I make a conscious effort to formulate simple, some might say naive, hypotheses and to confront them with quantitative data from the real world. There are, for example, as many graphs in the book as illustrations of animals. My aim, though, has not been to test out the principles of Darwinism, but rather to sharpen our focus on physiological adaptations, given the assumption that Darwinism is approximately correct. Whether or not I succeed remains for the reader to decide.
Download or read book Insect physiology written by Vincent B. Wigglesworth and published by Springer. This book was released on 2013-11-11 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: years ago extensive advances have been made in all parts of the subject. Full-sized textbooks have been devoted to it; notably The Principles of Insect Physiology by the present author, the three volume Physiology of the Insecta edited by Morris Rockstein, and Insect Biochemistry by Darcy Gilmour; and articles describing the most recent advances in the physiology and biochemistry of insects appear in the Annual Review of Entomology, in Advances in Insect Physiology and elsewhere. References in this edition have therefore been confined to such textbooks and reviews, to a few recent papers which have not yet become incorporated in this way, and to a limited number of other papers which provide useful starting-points for further reading. I The Integument The key to much of the physiology of insects is to be found in the nature of their cuticle. As was first shown by Haecke1, the cuticle is the product of a single layer of epidermal cells. It is often described as being composed of non-living material; but in fact the epidermal cells give off fine filaments contained within the so-called 'pore canals', which run through the substance of the cuticle and often come within less than a micron of the surface. Cuticle Structure As described from stained sections the cuticle consists of two primary layers, the endocuticle which makes up the greater part, and a thin refractile epicuticle on the surface, usually not more than one micron in thickness.
Download or read book Shifting Standards written by Allan Franklin and published by University of Pittsburgh Press. This book was released on 2018-11-24 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Shifting Standards, Allan Franklin provides an overview of notable experiments in particle physics. Using papers published in Physical Review, the journal of the American Physical Society, as his basis, Franklin details the experiments themselves, their data collection, the events witnessed, and the interpretation of results. From these papers, he distills the dramatic changes to particle physics experimentation from 1894 through 2009. Franklin develops a framework for his analysis, viewing each example according to exclusion and selection of data; possible experimenter bias; details of the experimental apparatus; size of the data set, apparatus, and number of authors; rates of data taking along with analysis and reduction; distinction between ideal and actual experiments; historical accounts of previous experiments; and personal comments and style. From Millikan's tabletop oil-drop experiment to the Compact Muon Solenoid apparatus measuring approximately 4,000 cubic meters (not including accelerators) and employing over 2,000 authors, Franklin's study follows the decade-by-decade evolution of scale and standards in particle physics experimentation. As he shows, where once there were only one or two collaborators, now it literally takes a village. Similar changes are seen in data collection: in 1909 Millikan's data set took 175 oil drops, of which he used 23 to determine the value of e, the charge of the electron; in contrast, the 1988-1992 E791 experiment using the Collider Detector at Fermilab, investigating the hadroproduction of charm quarks, recorded 20 billion events. As we also see, data collection took a quantum leap in the 1950s with the use of computers. Events are now recorded at rates as of a few hundred per second, and analysis rates have progressed similarly. Employing his epistemology of experimentation, Franklin deconstructs each example to view the arguments offered and the correctness of the results. Overall, he finds that despite the metamorphosis of the process, the role of experimentation has remained remarkably consistent through the years: to test theories and provide factual basis for scientific knowledge, to encourage new theories, and to reveal new phenomenon.

Download or read book Historical Atlas of Central Europe written by Paul Robert Magocsi and published by University of Toronto Press. This book was released on 2018-11-12 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central Europe remains a region of ongoing change and continuing significance in the contemporary world. This third, fully revised edition of the Historical Atlas of Central Europe takes into consideration recent changes in the region. The 120 full-colour maps, each accompanied by an explanatory text, provide a concise visual survey of political, economic, demographic, cultural, and religious developments from the fall of the Roman Empire in the early fifth century to the present. No less than 19 countries are the subject of this atlas. In terms of today's borders, those countries include Lithuania, Poland, and Belarus in the north; the Czech Republic, Austria, Slovenia, Croatia, Hungary, and Slovakia in the Danubian Basin; and Serbia, Bosnia-Herzegovina, Montenegro, Romania, Moldova, Bulgaria, Macedonia, Albania, and Greece in the Balkans. Much attention is also given to areas immediately adjacent to the central European core: historic Prussia, Venetia, western Anatolia, and Ukraine west of the Dnieper River. Embedded in the text are 48 updated administrative and statistical tables. The value of the Historical Atlas of Central Europe as an authoritative reference tool is further enhanced by an extensive bibliography and a gazetteer of place names - in up to 29 language variants - that appear on the maps and in the text. The Historical Atlas of Central Europe is an invaluable resource for scholars, students, journalists, and general readers who wish to have a fuller understanding of this critical area, with its many peoples, languages, and continued political upheaval.
Download or read book The Explosion of Life Forms written by and published by John Wiley & Sons. This book was released on 2021-04-13 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the essential characteristics of living beings is the explosion of variety in their forms that is intrinsically linked to the diversity of the environments they have adapted to. This book, the result of collaboration between international specialists, analyzes the multiplicity of these morphologies. It explores the origin of forms, their role in defining living things, and the relationship between form and function. It exposes the role of genes and epigenetics and examines the forms of bacteria, protists and plants. The Explosion of Life Forms also studies the memory of animals and their sensory processes, the forms of robots (built in the image of living things), and medical technologies aimed at restoring damaged living forms. Finally, this work questions a common principle of construction in the diversity of forms, as well as the idea of an abandonment of the form, a possible hidden defect of some modern philosophies.
