[QUOTE]Originally posted by Monica: [QB] msjen jen... I happen to know how to research for it though <IMG SRC="http://www.egyptsearch.com/forums/wink.gif"> I knew it was certainly a mathematical formula based on some other mathematical formula, but I did'nt know EXACTLY WHICH <IMG SRC="http://www.egyptsearch.com/forums/tongue.gif"> I know a bit more, now. I'll share it with you, Adoula's style (very informative style by the way): [Eratosthenes made a surprisingly accurate measurement of the circumference of the Earth. Details were given in his treatise On the measurement of the Earth which is now lost. (hahahahaha) However, some details of these calculations appear in works by other authors such as Cleomedes, Theon of Smyrna and Strabo. Eratosthenes compared the noon shadow at midsummer between Syene (now Aswan on the Nile in Egypt) and Alexandria. He assumed that the sun was so far away that its rays were essentially parallel, and then with a knowledge of the distance between Syene and Alexandria, he gave the length of the circumference of the Earth as 250,000 stadia.] And stadia is a Greek measure...you go check it ...got to run <IMG SRC="http://www.egyptsearch.com/forums/rolleyes.gif"> There you go funny girl...we missed your posts! Keep posting let's reach 500 big ones on this thread, before the end of the year ...can you do it??? If you're game (as well as the other dear friends reading this)it's only 9 posts to go so here is an opening: What do you think is the difference between internet Chemistry....and face to face chemistry between people??? And how can it be that through the internet, the chats are hot and the emails sizzle (between a virtual couple) and then no reaction what so ever - in some cases - when the real encounter occurs? Looking forward to some ( 9 posts at least) interesting theories... End of the year <IMG SRC="http://www.egyptsearch.com/forums/cool.gif"> Monica QUOTE]Originally posted by msjen: [b] do you happen to know how he did that? curious jen x[/b][/QUOTE] [This message has been edited by Monica (edited 20 December 2003).] [/QB][/QUOTE]
