Of all the arts, photography has perhaps the closest association with science and technology: the physics of light and colour combined with chemistry to capture images. Lo-Fi Photography is an ideal introduction to the science that lies behind photography and the array of simple methods that can be used to capture light and create images. From making homemade cameras to accessible techniques, the goal of this book is to provide all readers with access to this interesting form of creative photography via how-to guides, plans and some tips and tricks. In addition to the theory and hands-on guidance, this book also explores Lo-Fi photography as a distinct art form and provides further reading and excellent sources for diving even deeper into the world of experimental photography. Lo-Fi Photography is both a superb introduction to anyone curious about the science of photography and a first-rate guide to the world of experiemental photography for inquisitive photographers.

A brief overview of astronomy and cosmology is presented in five different ways, through the lenses of space, time, evolution, process, and structure. Specific topics are chosen for their contribution to a "big picture" understanding of the interconnectedness of knowledge in astronomy and cosmology. Thus, many topics (stellar astronomy for example) are treated in multiple sections, but from different viewpoints¿for example, sizes and distances of stars (space); when stars appeared in the history of the universe (time); stellar evolution (evolution); hydrostatic equilibrium and stellar spectra (process); and stellar structure (structure). Some topics traditional to the introductory astronomy curriculum¿eclipses and lunar phases, for example¿are omitted altogether as they are inessential for the big-picture goals of the book, and excellent summaries are easily available elsewhere. On the other hand, the book treats some topics not usually covered in an introductory astronomy course, forexample the roles played by equilibrium processes and symmetry in our understanding of the universe. The level is for the beginning undergraduate, with only basic skills in rudimentary algebra assumed. But more advanced students and teachers will also find the book useful as both a set of practical tools and a point of departure for taking stock (in five different ways) of the current state of knowledge in astronomy and cosmology.

Uses art photography as a point of departure for learning about physics, while also using physics as a point of departure for asking fundamental questions about the nature of photography as an art. Although not a how-to manual, the topics centre around hands-on applications, illustrated by photographic processes easily accessible to students.

Uses art photography as a point of departure for learning about physics, while also using physics as a point of departure for asking fundamental questions about the nature of photography as an art. The topics centre around hands-on applications, most-often illustrated by photographic processes that are inexpensive and easily accessible to students.
