Cloth. Zustand: Fine. Zustand des Schutzumschlags: Very Good. First Edition. Hardcover. First Edition. A Book of Animals. Very slight shelf wear to top edge of D/J. This fascinating and lively book exxplores and unusual aspect in the animal kingdom - the part animals have played in our cultural and religious life through the centuries, and our ever-changing relationship with animals both wild and domestic. In an amazing variety of ways we have been inspired, frightened, awed and befriended by the animals, art, literature are rich in association which are still all around us, often turning up in the most unexpected places in modern everyday life. Illustrations. 176 pp. (We carry a wide selection of titles in The Arts, Theology, History, Politics, Social and Physical Sciences. Academic and Scholarly books and Modern First Editions ,and all types of Educational Reference Literature.). William Geldart (illustrator).…

Taschenbuch. Zustand: Neu. Neuware - Why does the Moon's altitude and azimuth (where it rises and sets) vary from night to night What do people from the equator to polar regions see The Moon is a creature of the tropics: from the northern hemisphere at mid-latitudes we see it to the south and similarly, from the southern hemisphere to the north. It moves above and below the Earth's equatorial plane during the month so we see it in slightly different positions each night. As you move away from tropical latitudes it will appear progressively lower, and due to the Earth's fixed tilt, the Moon is seen higher in winter than in summer. The Moon's apparent altitude depends on your latitude on Earth and the Moon's declination (the angle it makes with the Earth's equatorial plane). The formula for maximum altitude is given. The Moon can only be seen at the zenith within, at the most, 28.5° latitude north and south. The author presents charts of the Moon's altitude as seen from various latitudes in summer and winter and discuss upper and lower transits.…

Taschenbuch. Zustand: Neu. Neuware - Observations were made over a great lake with a clear view to the horizon of moonsets that displayed a duplicate image below. This is known as an Etruscan Vase or an Omega effect because of the shape. The cause of the inferior image is considered: refraction, reflection, or gravitation. 'Since the phenomenon is only seen from a low vantage point looking over a level surface to a clear horizon it underscores the importance of the observer's position.'The cause of the inferior image observed on the horizon during Moon/Sun set/rise is examined. A refraction model suggests that light from the geometric moon beyond the horizon passes through air layers of different temperature and density to bend down to the observer. Yet this is inadequate in explaining the rising inferior image which is robust and not mirage-like. The author considers if refraction, reflection or gravitation play a role in its appearance. …

Taschenbuch. Zustand: Neu. Neuware - One of our pervasive conditions is to be immersed in radiation, but what we see is constrained to the visual spectrum, to a sensitivity of about 1/10th of a second, and by our position. Rather than being limitations, these constraints provide a framework in which we can navigate, examine and think about the world. The author considers the taken-for-granted phenomena of moonlight on water and sunlight on snow to show that our position is crucial: when we move bright specular reflections follow us on top of the diffuse background.…

Taschenbuch. Zustand: Neu. Neuware - We assume we move about in a three-dimensional world and this is borne out by experience. Interestingly, the whole visualized environment emanates from a vanishing point on the horizon and is focussed on each individual observer. The author discusses Newton's Inverse Square Law, Max Jammer's Concepts of Space and considers how various geometries (Euclidean, Hyperbolic, Spherical) may coexist for the observer.…

Taschenbuch. Zustand: Neu. Neuware - Imagine standing on the shore of a large lake looking to a clear horizon. The Moon is moderately high and casts a sparkling line on the water that is distinctly centred on you.The author considers such common situations as moonlight on water and sunlight on snow to show that our position is crucial: when we move bright specular reflections follow us on top of a diffuse background.…

Taschenbuch. Zustand: Neu. Neuware - Observations were made over a great lake with a clear view to the horizon of moonsets that displayed a duplicate image below. This is known as an Etruscan Vase or an Omega effect because of the shape. Three causes of the inferior image are considered: refraction, reflection, or gravitation. 'Since the phenomenon is only seen from a low vantage point looking over a level surface to a clear horizon it underscores the importance of the observer's position.'. …

Taschenbuch. Zustand: Neu. Neuware - Why does the Moon's altitude and azimuth (its position along the horizon) vary from night to night What do people at the equator or in polar regions see The Moon is a creature of the tropics: from mid-to-high latitudes, about midnight we look towards the equator to see it at its highest altitude, and it will appear progressively lower as you move away from the tropics. From high latitudes it undulates just above the horizon for multiple days and nights. From whatever latitude, each night the Moon's path and altitude vary because its orbit is tilted relative to the Earth's equator, and due to the fixed axial tilt of the Earth in its orbit, the Moon appears higher in winter than in summer.…

Taschenbuch. Zustand: Neu. Neuware - Des observations ont été effectuées au-dessus d'un grand lac offrant une vue dégagée sur l'horizon des couchers de lune, dont l'image était reproduite en dessous. Ce phénomène est appelé effet vase étrusque ou effet Oméga en raison de sa forme. Trois causes sont envisagées pour expliquer cette image de qualité inférieure: la réfraction, la réflexion ou la gravitation. Comme ce phénomène n'est visible que depuis un point d'observation bas, surplombant une surface plane vers un horizon dégagé, il souligne l'importance de la position de l'observateur.…
