This is often the 1st scholarly selection of articles concerned about the cultural astronomy of the African continent. It weaves jointly astronomy, anthropology, and Africa and it comprises African myths and legends concerning the sky, alignments to celestial our bodies came upon at archaeological websites and at locations of worship, rock paintings with celestial imagery, and medical considering published in neighborhood astronomy traditions together with ethnomathematics and the production of calendars.

Study into the geological tactics working on Mars is dependent upon interpretation of pictures and different facts back via unmanned orbiters, probes and landers. Such interpretations are in keeping with our wisdom of strategies taking place on the earth. Terrestrial analog experiences hence play a major position in realizing the geological positive aspects saw on Mars.

In the afternoon the tip of the shadow traces a pattern in the sand similar to that of the morning. The patterns are mirror images of each other, lying across an imaginary line of symmetry. That line pointed to a mysterious area to the north, around which all the stars of the sky revolve. This realm of the north, where stars never set, was viewed by the Egyptians as a timeless place of eternity. There is more to the gnomon, for it also measures time by the tip of its moving shadow. The patterns on the sand are symmetrical about that time when the sun reaches its highest point in the sky, when the shadow is shortest.
S. (1990): Methods of Data Analysis in the Social and Behavioural Sciences. Enugu. Auto Century Publishing Co. Ltd. A Brief Outline on the Geographical Background of Africa Basil U. Eze Introduction This write-up makes an attempt at presenting a basic outline on some of the physical and human features with which to identify the continent of Africa. Even in a study such as African Cultural Astronomy a researcher needs to know about Africa. This is strictly a basic outline but promises to be an interesting reading.
The mechanical clocks needed to be calibrated by sundials, probably at the time of local solar noon. When the entire dial is tilted toward the north celestial pole and the gnomon is exactly parallel to the axis of the earth, one has constructed a miniature earth. When the dial is tilted to the earth’s pole it mimics the earths equatorial plane, as illustrated in this picture of the sun dial at the University of Colorado (Figure 4). Experiments 1. Establish the direction to true north. a. Approximate Method: The easiest method to establish north-south is to erect a gnomon and place markers at the tip of the shadow over the course of the day and note where is it shortest.
