ERATOSTENES' EXPERIMENT
On Friday, September 22nd, 2023 (the day of the autumn equinox), at solar noon at 1:02 pm, our students in première will perform Eratosthenes’ historic experiment in the schoolyard! Equipped with a gnomon (an astronomical instrument consisting of a vertical rod casting the sun’s shadow on the ground), they’ll be able to determine the earth’s circumference.
