#10565 Physical Geography - Latitude and Longitude: A Global Address (Run time 33 min.) DVD $79.95
Every point on earth has a unique global address, which is described by the system of latitude and longitude. With today's satellite navigation systems, we can find latitude and longitude positions with an accuracy of a few centimeters. This program describes how the system of latitude and longitude works, clearly defining key terms and concepts with the use of diagrams, illustrations, and video footage. The history of latitude and longitude is examined, from the early experiments and charts of Eratosthenes and Ptolemy to the inventions of the late 18th century allowing mariners to find longitude at sea. The video also reviews the use of latitude and longitude today, including electronic navigation and Global Positioning System satellite technology. This video is an excellent resource for geography, world history, and earth science classes. A Cambridge Educational Production. Correlates to the National Science Education Standards developed by the National Academies of Science, Project 2061 Benchmarks for Science Literacy from the American Association for the Advancement of Science, and the National Geography Standards from the National Geographic Society.One 30-minute video.

#34260 Physical Geography - The True Image of the Earth (Run time 30 min.) DVD $89.95
Galileo's recantation in 1633 opened a gap between Christianity and science, a separation that widened as the first great age of European exploration came to a close. This program studies the second great age ushered in during the latter half of the 18th century amidst a thickening web of French and British colonialism-an age in which maps and charts facilitated political and economic objectives far more than religious concerns. In this program, the voyages of James Cook, the mapping of the Sahara, and the arbitrary partitioning of the Middle East clearly demonstrate the use of cartography in the service of empire.
