Eratosthenes festivity 2018

Eratosthenes festivity 2018

The Eratosthenes Festivity has become an annual tradition that takes place every year on 21 June at the Bibliotheca Alexandrina; It is designed for preparatory school students, and includes a series of activities that revolve around the methodology Eratosthenes applied in measuring the Earth’s circumference 2000 years ago. On the 21st of June, the day of summer solstice, the 21st century school students conduct Eratosthenes’ experiment on the BA Plaza, and in Aswan (Upper Egypt) to measure the circumference of Earth.

This year, the PSC team has reached out for more partners in order to promote the goal of the event. We had international partners: Argentina, Brazil, Colombia, Italy, Slovinia, Croatia, France, Greece, India, Romania, Tunisia. In addition, we had local partners from the Exploration Centers for Science and Technology. The Festivity comprises a fieldtrip to Elephantine Island in Aswan, interactive workshops and lectures.
