Evangelical Mind
Through an in-depth study of the thought and intellectual formation of Nathanael Burwash (1839-1918), a little-known but highly influential Canadian educator and Methodist theologian, Marguerite Van Die presents a picture of one of the most unsettling periods in the Christian church. During Burwash's life, Canadian Methodist thought and education had to deal with the impact of biblical criticism, idealist thought, and the evolutionary theory of Darwin. Burwash saw himself as following in the footsteps of an earlier generation of Methodists, led by Edgar Ryerson. This vision was reflected in his views on childhood nurture and moral nationalism and his support of university federation in Ontario.
Pigment of the Imagination
Pigment of the Imagination chronicles the story of phytochrome, the bright-blue photoreversible pigment through which plants constantly monitor the quality and presence of light. The book begins with work that led to the discovery of phytochrome and ends with the latest findings in gene regulation and expression. The phytochrome story provides a paradigm for the process of scientific discovery. This book should thus be of interest to scientists who work on phytochrome and related subjects in plant science, as well as to all scientists and science historians interested in how a scientific research field begins, develops, and matures.Documents the science and history of phytochrome research over an 80 year spanCombines information from scientific literature, archival documents, and in-person inteviewsDescribes in scholarly and readable style an elegant example of biological discoveryAccessible to researchers and students in all areas of science and history of science

The Blue Light Syndrome
Investigations on the specific effects of blue light on plants began some fifty years ago. In re cent years the growing awareness of blue-light-in duced phenomena in plants, microorganisms, and animals has accelerat ed and expanded this research into an ever-increasing variety of blue light effects in biological systems. In 1977, J .A. Schiff and W .R. Briggs proposed a specific meeting to present and summarize the various blue-light effects and to discuss their mechanisms and possible photoreceptors. In view of the variety of re sponses and the range of organisms affected by blue light the term Blue Light Syndrome seemed to be the only appropriate one for the meeting. With the help of the I...

Light in Biology and Medicine
Almost all life depends on light for its survival. It is the ultimate basis for the food we eat (photosynthesis), and many organisms make use of it in basic sensory mechanisms for guiding their behaviour, be it through the complex process of vision, or by the relatively more simple photosens itivity of microorganis~urthermore, light has profound implications for the field of medicine, both as a cause of disease (ie UV damage of DNA), and as a therapeutic agent (ie photodynamic therapy). These and other processes are the basis for the science of photobiolog~ which could be defined as the study of the effects of (visible and ultraviolet) light (from both the sun and artificial sources) on livi...
