There would be no life on Earth without light from the Sun, and life would not be as highly evolved as it is had it not made the best use of light's energy and information for using photosynthesis, biological clocks, and vision. In Light and Life, Michael Gross explores six major aspects of the complex and fascinating interplay between light and life, ranging from the mythical role of the Sun in ancient cultures to the latest advances in scientific research, covering photosynthesis, bioluminescence, vision, perception, and biological clocks. - ;Light, like no other physical phenomenon, is linked in a wide variety of ways with the biological phenomenon of life. We can read this page because light is reflected from it, and carries the information to the retina; the oxygen we breathe was produced by photosynthesis; our sense of alertness relies on our biological clock, set using the cues of light and dark. Michael Gross explores the symbiotic relationship of light and life in this intriguing and entertaining book. Starting with astronomy and our relationship with the Sun and dependence on photosynthesis, he then turns to some of the stranger outcomes of the relationship - bioluminescent creatures, and their evolutionary significance. Finally he looks at the influence of light on biological time-keeping, the focus of much current scientific research. Life would not be here without light, and it would not have evolved as it has done had it not made the best possible use of light's energy and information content for using photosynthesis, biological clocks, and vision. This book explores all these aspects of the fascinating interplay of these two phenomena in a lively manner using many intriguing examples. -

The new edition of this authoritative text provides an interdisciplinary treatise of all aspects of the interactions between light and the living world. It starts with a description of the physics of light, and how to deal with it in experiments and observations. The phenomena described in the rest of the book covers all organisms: how light is used by organisms for obtaining energy for life processes, for gathering information about the environment, and for communicating with others of the same or other species. The book also describes "bad" effects of light in causing disease or contributing to formation of environmental toxins. New techniques used by scientists to investigate life processes using light are also explored in the volume. Written by experts in the field, Photobiology: The Science of Life and Light, 3e is a valuable and accessible resource for both advanced undergraduates and established researchers.

Light and Life in the Universe: Selected Lectures in Physics, Biology and the Origin of Life is a collection of lectures given at the 1964 Nuclear Research Foundation Summer Science School for High School Students, held at the University of Sydney, Australia, on January 6-17, 1964. The papers explore various aspects of life, both on earth and in the universe generally. Emphasis is placed on the ""units"" of living matter, how life may have started on earth, and the possibility of life on other planets. This book is comprised of 15 chapters and begins with a brief description of some of the properties of atoms and how they join up to form molecules, as well as some of the properties of the central core of each atom. The discussion then turns to electromagnetic radiation, highlighting the difficulties originally encountered by Ernest Rutherford's picture of the atom. Subsequent chapters focus on the influence of gravitational fields; the origin of the solar system; the evolution of life on earth; and link between the primordial atmosphere and the origin of life. The functions of proteins, the practical effects of biology on humans, and the replication of living molecules are also considered. This monograph is written specifically for fourth-year high school students interested in astronomy, physics, chemistry, and biology.

Without light there would be no life in the sea. Since the seas were the cradle for the evolution of all life forms, the theme of this book is central to our understanding of the interaction between living organisms and their environments. To express the breadth of research in this area, leading experts in topics as diverse as satellite imagery and molecular biology have contributed to this collection of essays on light and life in the sea, first published in 1990. Intended for all with an interest in the marine environment, this book aims to present the reader with a sampler of the exciting research that is underway and to provide an introduction to its broad compass.

Nora Heysen grew up at The Cedars near the Adelaide Hills town of Hahndorf, and was deeply influenced by her father, Hans Heysen. Nora Heysen: Light and life explores a notable career spanning seven decades, during which the artist painted some of Australia's most outstanding self-portraits, became the country's first female war artist, and was the first woman to win the prestigious Archibald Prize. Curator and author Jane Hylton has written extensively on Australian art and has curated numerous exhibitions. In 2000 she left the position of Curator of Australian Art at the Art Gallery of South Australia to become a freelance consultant.
