April Fools' Day

Special event : zero shadow


It is the 3rd time we could experiment with a partner observing the same experimental conditions as Eratosthenes in Aswan.

The figures and calculations are so easy on such a day?

This event is a double one, as it happens on 1st april. .. This isn't a joke!
