Introduction to Earth Sciences I Introduction to Earth Sciences I Topic 1 The Earth's Macroscopic Properties and What They Can Tell Us To get some very basic descriptions of the Earth we will start by describing some of the simplest of all the Earth's properties - how big, how heavy, how hot, how strong - and how they were deduced. 1.1 The Earth's Size and Shape Centuries ago people had very little idea about the total size of the Earth and hardly any notion of its shape. One of the earliest attempts to estimate the Earth's size was done by Eratosthenes about 200 B.C. If the Earth were flat the "sun angle" would be the same everywhere. If the Earth is round then the "sun angle" would change and he reasoned that the amount of sun angle change had to have something to do with the Earth's total size. Because of this he knew about angles. From there he could get the circumference of the Earth which he estimated at 24,500 miles, only about 50 miles off current best estimate.

David Rumsey Historical Map Collection| Google Maps Launch Google MapsLaunch Maps in LUNA Browser The over 120 historical maps in the Google Maps have been selected by David Rumsey from his collection of more than 150,000 historical maps; in addition, there are a few maps from collections with which he collaborates. These maps can also be seen in the Gallery layer of Google Earth, Rumsey Historical Maps layer, and in the Google Earth viewers on this website. All the maps contain rich information about the past and represent a sampling of time periods (1680 to 1930), scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. The original historical maps are first made into digital images by scanning them with high resolution digital cameras. Processing and hosting of the Rumsey Historical Maps in Google Maps is provided by Geogarage.

What Is Globalization? Finally, a definition of globalization that one can understand and to which we now can relate: Question: What is the truest definition of Globalization? Answer: Tragically, Princess Diana’s death. Question: Why? An English princess with an Egyptian boyfriend crashes in a French tunnel, driving a German car with a Dutch engine, driven by a Belgian who was drunk on Scottish whiskey, followed closely by Italian paparazzi on Japanese motorcycles; treated by an American doctor, using Brazilian medicines. This is sent to you by an American, using Bill Gate’s technology and you are probably reading this on your computer, that uses Taiwanese chips and a Korean monitor, assembled by Bangladeshi workers in a Singapore plant; transported by Indian lorry-drivers, hijacked by Indonesians, unloaded by Sicilian longshoremen and trucked to you by illegal Mexican workers… And that is what Globalization is. ~ source unknown ~
