Eratosthenes 2018

Students from all continents cooperate and collaborate to reproduce one of the science's 10 most beautiful experiments of all time: Eratosthenes' measurement of the Earth's circumference.

Project Journal

  • June is over and was a very fruitful month though difficult to make measurements because of the unusual unsteady weather in Europe and because most of the schools were having exams Making this video for June solstice was a GREAT pleasure!
    Looking forward a report from Alexandia's Library (we have sent them MANY good measurements).

    Have a beautiful summer, dear friends!
    Maybe we could have "holidays postcards" with our measurements if we visit a special place during summer, couldn't we? ;)
