Category Theory in Physics, Mathematics, and Philosophy (Springer Proceedings in Physics #235)
by Marek Kuś Bartłomiej SkowronThe contributions gathered here demonstrate how categorical ontology can provide a basis for linking three important basic sciences: mathematics, physics, and philosophy. Category theory is a new formal ontology that shifts the main focus from objects to processes.The book approaches formal ontology in the original sense put forward by the philosopher Edmund Husserl, namely as a science that deals with entities that can be exemplified in all spheres and domains of reality. It is a dynamic, processual, and non-substantial ontology in which all entities can be treated as transformations, and in which objects are merely the sources and aims of these transformations.Thus, in a rather surprising way, when employed as a formal ontology, category theory can unite seemingly disparate disciplines in contemporary science and the humanities, such as physics, mathematics and philosophy, but also computer and complex systems science.
Catenary Optics
by Xiangang LuoThis book offers the first comprehensive introduction to the optical properties of the catenary function, and includes more than 200 figures. Related topics addressed here include the photonic spin Hall effect in inhomogeneous anisotropic materials, coupling of evanescent waves in complex structures, etc. After familiarizing readers with these new physical phenomena, the book highlights their applications in plasmonic nanolithography, flat optical elements, perfect electromagnetic absorbers and polarization converters. The book will appeal to a wide range of readers: while researchers will find new inspirations for historical studies combining mechanics, mathematics, and optics, students will gain a wealth of multidisciplinary knowledge required in many related areas. In fact, the catenary function was deemed to be a “true mathematical and mechanical form” in architecture by Robert Hooke in the 1670s. The discovery of the mathematical form of catenaries is attributed to Gottfried Leibniz, Christiaan Huygens and Johann Bernoulli in 1691. As the founders of wave optics, however, Hooke and Huygens did not recognize the importance of catenaries in optics. It is only in recent decades that the link between catenaries and optics has been established.
Caterpillars in the Middle: Tritrophic Interactions in a Changing World (Fascinating Life Sciences)
by Robert J. Marquis Suzanne KopturCaterpillars are excellent model organisms for understanding how multiple selective forces shape the ecology and evolution of insects, and organisms in general. Recent research using the tools of modern molecular biology, genetics, metabolomics, microbial ecology, experiments conducted at a global level, network analysis, and statistical analyses of global data sets, combined with basic natural history, are yielding exciting new insights into caterpillar adaptations and ecology. The best way to view these research advances is within a framework of tri-trophic interactions. This is a timely topic for research given the central role of caterpillars and plants in the ecology and trophic structure of terrestrial communities. This book is unique in that it contains chapters from a team of experts on a diversity of key topics within caterpillar-plant interactions. This volume brings together contributions by researchers from around the globe, working in both tropical and temperate habitats, and in human-managed and more natural habitats. It is a significant contribution to our understanding of insect biology, and the role that insects, as represented by caterpillars, play in a world increasingly dominated by humans and one in which threats to insect biodiversity are mounting.Chapter 11 is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
Catfishes, a Highly Diversified Group: Volume 1: Their Outstanding Biology
by Roberto E. Reis Gloria ArratiaThe order of Catfishes (Siluriformes) is one of the largest in number of families, genera, and species. The group is found in most freshwaters and shallow saltwater bodies around the world. Its extraordinary evolutionary and biogeographic pathways leave many open questions on its origin and large diversification that make its study a complex subject, yet a fascinating field for research. Catfishes, a Highly Diversified Group is divided into two volumes. Volume 1 (Their Outstanding Biology, 14 chapters) aims to rectify the incomplete information on the enormous morphological diversity of the group, special habits and adaptations to specific environments, and morpho-functional characteristics of the catfishes. Volume 2 (Evolution and Phylogeny, 18 chapters) deals with evolutionary mechanisms and major evolutionary trends within Siluriformes, investigating new avenues concerning fossil and extant catfishes and relationships within and among families, using morphological and molecular evidence.

Catharanthus roseus: Current Research and Future Prospects
by Tariq Aftab M. Masroor A. Khan M. NaeemHistorical uses of Catharanthus roseus in the treatment of diabetes, fever, malaria, regulation of menstrual cycle, throat infection and chest complaints have been reported. Only few plants have the anticancer properties and periwinkle is one of them. The physiologically important and antineoplastic alkaloids, vinblastine and vincristine, are mainly present in leaves and antihypertensive alkaloids are found in roots such as ajmalicine, serpentine and reserpine. Vincristine and vinblastine have extensive use in modern medicine as potential anticancer compounds. Above medicinal properties are worth attracting the attention of plant scientists to increase the secondary metabolites of this plant.

Cathedrals Of Science: The Personalities And Rivalries That Made Modern Chemistry
by Patrick CoffeyIn Cathedrals of Science, Patrick Coffey describes how chemistry got its modern footing-how thirteen brilliant men and one woman struggled with the laws of the universe and with each other. They wanted to discover how the world worked, but they also wanted credit for making those discoveries, and their personalities often affected how that credit was assigned. Gilbert Lewis, for example, could be reclusive and resentful, and his enmity with Walther Nernst may have cost him the Nobel Prize; Irving Langmuir, gregarious and charming, "rediscovered" Lewis's theory of the chemical bond and received much of the credit for it. Langmuir's personality smoothed his path to the Nobel Prize over Lewis. Coffey deals with moral and societal issues as well. These same scientists were the first to be seen by their countries as military assets. Fritz Haber, dubbed the "father of chemical warfare," pioneered the use of poison gas in World War I-vividly described-and Glenn Seaborg and Harold Urey were leaders in World War II's Manhattan Project; Urey and Linus Pauling worked for nuclear disarmament after the war. Science was not always fair, and many were excluded. The Nazis pushed Jewish scientists like Haber from their posts in the 1930s. Anti-Semitism was also a force in American chemistry, and few women were allowed in; Pauling, for example, used his influence to cut off the funding and block the publications of his rival, Dorothy Wrinch. Cathedrals of Science paints a colorful portrait of the building of modern chemistry from the late 19th to the mid-20th century.

Cats and Conservationists: The Debate Over Who Owns the Outdoors (New Directions in the Human-Animal Bond)
by Anna L. Peterson Dara M. WaldCats and Conservationists is the first multidisciplinary analysis of the heated debate about free-roaming cats. The debate pits conservationists against cat lovers, who disagree both on the ecological damage caused by the cats and the best way to manage them. An impassioned and spirited conflict, it also sheds light on larger questions about how we interpret science, incorporate diverse perspectives, and balance competing values in order to encourage constructive dialogue on contentious social and environmental issues. <p><p>On one side of the cat debate stand many environmentalists, especially birders and conservation organizations, who believe that outdoor cats seriously threaten native wildlife. On the other side are many animal welfare advocates, who believe that outdoor cats generally do not pose a major ecological threat and that it is possible for cats and wildlife to coexist. They believe that it is possible, mainly through trap-neuter-return projects (TNR), to keep free-roaming cat populations in check without killing large numbers of cats. <p><p>Careful analysis suggests that there remain important questions about the science on both cat predation and TNR effectiveness. Yet both sides of the conflict insist that the evidence is clear-cut. This false certainty contributes to conflict between conservationists and cat lovers, and obscures common goals that could generate constructive discussions and collaborative efforts among scientists, policymakers, conservationists, and animal welfare advocates. Cats and Conservationists aims to facilitate such collaboration in order to manage outdoor cats and minimize the damage they cause. It also offers models for constructive debates about the public role of science in other polarized public conflicts over science and environmental topics.
