“Observing the Sun” is for amateur astronomers at all three levels: beginning, intermediate, and advanced. The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun. Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations. Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. “Observing the Sun” provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun.

John Davenall Turner, one of western Canada's first and most respected artists, lived in both Edmonton and Calgary, and painted the countryside around him in its various moods for almost all of his eighty years. Turner's reminiscences are written with style, panache, and wit. Includes 31 color reproductions of John Davenall Turner's paintings and many of his humourous drawings.

Follow the Sun will guide you through all aspects of architectural photography, from the genre’s rich history to the exciting new approaches brought by the advent of the digital age. It explains how to use the powerful tools of digital photography while employing many of the skills and traditions of the established genre. Written to be accessible to professionals, amateurs, and students alike, this book will be useful for photographers exploring architecture as fine artists, on editorial assignments, or on commercial shoots. Key features include: • Example photographs and diagrams • Historical background of architectural photography • Advice on essential equipment • How to plan a shoot to your advantage • How to use tilt-shift lenses for architecture • Editing workflow and strategies • Interviews with architectural photographers Peter Aaron, Magda Biernat, Ty Cole, and Elizabeth Felicella.

Space Fluid Hydromechanics is an original research treatise dealing with the nature of presently debated or unknown phenomena in the universe. Theories advanced: Space is filled with a fluid of essentially zero viscosity. This fluid is structured in filaments, not discrete particles. This structure is seen from the microscopic to the telescopic. Nebulae seen in the night sky are not universes of billions of suns, but are seen by reflected sunlight. This also applies to the Milky Way. The mechanics of this space fluid not only accounts for the physical world we see, but also for the phenomena of electricity, magnetism, light, heat, and pressure. These phenomena are characteristics of the Earth's space field. The indicated space pressure near the Earth is in the vicinity of one hundred billion pounds per square inch. There is only one source of available energy, and this source is differential space pressure. There exists electrodynamic space fields in size from a single cell to planetary nebulae. An atomic blast creates an instantaneous space field. The Earth's space field has optical properties. We can never know with exactness the size, position, or distance of any object in space until these factors are applied. The true nature of the "rid shift" is primarily due to light being refracted by the Earth's space field. A constantly compensating equilibrium is maintained among all the objects in the solar system. The calamitous misinterpretation of the MichelsonaEUR"Morley experiment. The real interpretation. The factors that make the Sun hot make the Earth relatively warm. The surface of the Earth would be frozen at hundreds of degrees below zero if the Earth's only source of heat was radiation from the Sun. The objections to the currently supposed size of the universe and the distances to celestial objects. Why there is the spectrum displacement toward the red. There is no positive evidence that any object seen in space is a Sun similar to our own or a collector of suns. He mentions possible exceptions. The probable anatomy of what we see in space is shown in figure 164.

Trajectories followed by vehicles propelled by a constant thrust directed parallel to the velocity vector were calculated in nondimensional form for a range of initial thrust-weight ratios from 10 to 10−4 and for a range of jet velocities from those attainable with chemical rockets to infinity. Trajectories are presented both for the departure outward from any circular orbit and the inward return to any circular orbit. Results are given in the form of curves of radial distance, energy per unit mass (hyperbolic velocity), trajectory inclination, and velocity and angular distance as functions of time. Utilization of these charts to estimate weight requirements for interplanetary missions is discussed.
