Eckerman, C. (2011). Cars &vehicles (9) However, a simplified version of the method has been preserved, as described by Cleomedes.[15]. The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations. Eratosthenes was born in approximately 276 BC. The exact length of the units (stadia) he used is doubtful, and the accuracy of his result is therefore uncertain. The most enduring contribution of the Guidelines has been the articulation of the five fundamental themes of geography: 1) location; 2) place; 3) relationships within places (human-environmental interaction); 4) relationships between places (movement); and 5) regions. 2011. "Eratosthenes." [16] A geometric calculation reveals that the circumference of the Earth is the distance between the two cities divided by the difference in shadow angles expressed as a fraction of one turn. He may have measured the distances from Earth to both the Moon and to the Sun, but the historical accounts of both deeds are rather cryptic. and more. He also claimed that the rivers source was lakes. If you ask any geographer to name a person who was responsible for the founding of their discipline, theyre likely to say, Ptolemy.

A librarian named Hipparchus later placed lines of longitude at regular intervals, and this was improved even more by Ptolemy, who added cardinal directions and divided degrees into minutes and seconds. He calculated the size of the Earth using geometry and ratios based on sun observations. Who succeeded Eratosthenes as the chief librarian of Alexandria?
