Astronomy & Geography
The word astronomy means star. The Greeks named and studied over 850 stars, which is very impressive for their time period considering their lack of technology. Hipparchus was pretty brave in thinking that the Earth revolved around the sun because in those days people were killed for not thinking that everything in the universe revolved around the Earth.
Ptolemy wrote a book identifying around 8,000 places on Earth. They also invented longitude and latitude. The name geography means writing of the Earth. In Greece they had mild winters and long hot summers. Lastly Ptolemy knew that the Earth was round.
