The educational project 'Sea the Curve: The Experiment of Geosphere' seeks to reaffirm the spherical shape of the Earth using modern methodologies and international participation, scheduled for March 20, 2026, coinciding with the spring equinox. This initiative, which is a collaboration between the Foundation of Eugenides and the National Observatory of Athens, draws inspiration from the methodology of Eratosthenes. It brings together the school community, scientific research, and Greek shipping in an experiment with global significance.

The initiative involves participation from 60 schools in Greece and the diaspora, along with 15 Greek-owned vessels that will conduct measurements at sea, covering an impressive geographical range from England to Madagascar and across the Mediterranean to the Indian Ocean. During the event, students, educators, and sailors will simultaneously measure the length of the shadow of a vertical rod at different geographical latitudes, sending their collected data for analysis. This hands-on approach not only demonstrates the scientific principle of Earth's shape but also fosters collaboration among various communities.

In today's era, where misinformation about Earth's shape persists, such initiatives serve both educational and scientific purposes by engaging young minds and highlighting the importance of empirical evidence in understanding our planet. The collaborative nature of this project also emphasizes the role of international cooperation in advancing scientific literacy and promotes the intersection of education and maritime industry, showcasing how traditional scientific methods can still have relevant applications in the 21st century.
