The Optics Of Life

Optics--a field of physics focusing on the study of light--is also central to many areas of biology, including vision, ecology, botany, animal behavior, neurobiology, and molecular biology. The Optics of Life introduces the fundamentals of optics to biologists and nonphysicists, giving them the tools they need to successfully incorporate optical measurements and principles into their research. Sönke Johnsen starts with the basics, describing the properties of light and the units and geometry of measurement. He then explores how light is created and propagates and how it interacts with matter, covering topics such as absorption, scattering, fluorescence, and polarization. Johnsen also provides a tutorial on how to measure light as well as an informative discussion of quantum mechanics. The Optics of Life features a host of examples drawn from nature and everyday life, and several appendixes that offer further practical guidance for researchers. This concise book uses a minimum of equations and jargon, explaining the basic physics of light in a succinct and lively manner. It is the essential primer for working biologists and for anyone seeking an accessible introduction to optics. Some images inside the book are unavailable due to digital copyright restrictions.

This full-colour undergraduate textbook, based on a two semester course, presents the fundamentals of biological physics, introducing essential modern topics that include cells, polymers, polyelectrolytes, membranes, liquid crystals, phase transitions, self-assembly, photonics, fluid mechanics, motility, chemical kinetics, enzyme kinetics, systems biology, nerves, physiology, the senses, and the brain. The comprehensive coverage, featuring in-depth explanations of recent rapid developments, demonstrates this to be one of the most diverse of modern scientific disciplines. The Physics of Living Processes: A Mesoscopic Approach is comprised of five principal sections: • Building Blocks • Soft Condensed Matter Techniques in Biology • Experimental Techniques • Systems Biology • Spikes, Brains and the Senses The unique focus is predominantly on the mesoscale — structures on length scales between those of atoms and the macroscopic behaviour of whole organisms. The connections between molecules and their emergent biological phenomena provide a novel integrated perspective on biological physics, making this an important text across a variety of scientific disciplines including biophysics, physics, physical chemistry, chemical engineering and bioengineering. An extensive set of worked tutorial questions are included, which will equip the reader with a range of new physical tools to approach problems in the life sciences from medicine, pharmaceutical science and agriculture.

Twilight of the Idols presents a vivid, compressed overview of many of Nietzsche’s mature ideas, including his attack on Plato’s Socrates and on the Platonic legacy in Western philosophy and culture. Polt provides a trustworthy rendering of Nietzsche’s text in contemporary American English, complete with notes prepared by the translator and Tracy Strong. An authoritative Introduction by Strong makes this an outstanding edition. Select Bibliography and Index.

Have you wondered why the sky is blue? Why the sunset is red? How hummingbirds show us their many colors? Why the road ahead sometimes seems to have water on it, when it does not? Have you wondered how telescopes work to give a magnified image of distant objects? How do microscopes provide a magnified image of close objects? How do spectroscopes, eye glasses, cameras, binoculars, and similar instruments work? How do the simple rear view mirrors in cars dim and provide wide fields of view? In this book, William L. Wolfe attempts to describe many of the natural phenomena caused by light, and the optical devices that use it in terms everyone can understand.

Friedrich Hölderlin must be considered not only a significant poet but also a philosophically important thinker within German Idealism. In both capacities, he was crucially preoccupied with the question of tragedy, yet, surprisingly, this book is the first in English to explore fully his philosophy of tragedy. Focusing on the thought of Hegel, Nietzsche, Heidegger, and Reiner Schürmann, Véronique M. Fóti discusses the tragic turning in German philosophy that began at the close of the eighteenth century to provide a historical and philosophical context for an engagement with Hölderlin. She goes on to examine the three fragmentary versions of Hölderlin's own tragedy, The Death of Empedocles, together with related essays, and his interpretation of Sophoclean tragedy. Fóti also addresses the relationship of his character Empedocles to the pre-Socratic philosopher and concludes by examining Heidegger's dialogue with Hölderlin concerning tragedy and the tragic.
