The event, ‘On the Footsteps of Eratosthenes’, hosted by the Planetarium Science Center (PSC) at the Bibliotheca Alexandrina, brings together students from Alexandria and Aswan in Egypt working together via video-conference to calculate the Earth’s circumference, following the steps taken by Eratosthenes the third librarian of the ancient library of Alexandria. Students will be able to compare results on their calculations of the Earth’s circumference, and the degree of inclination of the Earth’s axis on 21 June, the first day of the summer solstice and the longest in the Solar year.
The PSC is hosting Mr. Denis Savoie, Director of the Palais de la Decouverte, France, to supervise the workshop and answer the students’ questions.
