The  Eratosthenes Photo Contest March 2019 has been announced!

 


REGISTRATION IS OPEN !

Welcome to the Eratosthenes Experiment platform!

  • Register by creating your account.
  • Come in contact with a registered school at the same longitude with you (this info will be provided to you by the organizing team)
  • Join efforts with the matching school and record your data
  • Calculate the circumference of the Earth

       Submit your data and take part to the Eratosthenes Photo Contest March 2019

This year, the experiment will take place on Thursday the 21st of March. You can perform the experiment in collaboration with another school on the same longtitude, if no other schools can be found on the same longitude -  for your matchup – you can consider the existence of a virtual school on the equator with experimental data 0 (shade of a one-meter stick measured at local noon). This way you can also have an accurate outcome by conducting the experiment by yourself. Schools that register till Monday 11th of March 12:00 CET will receive on Tuesday 12th of March an e-mail with the coordinates of potential matching schools along with the information (email) of their contact persons, so that they can communicate and arrange their match-up during the day of the experiment. Schools that register till Friday 15th of March 12:00 CET, will receive the same email during the day (after 16:00 CET). Schools that register on Friday 15th  of March after 12:00 CET and  until Tuesday 19th of March (15:00 CET), will receive email on Wednesday morning, 20th of March.

If you would like to perform the experiment by yourself on a date other than the 21st  of March, you can use this simulator  to find the exact angle from your school to the place where the sun rays are perpendicular to the ground. 

The Eratosthenes Experiment is organized under the support of the International Astronomical Union (IAU) in the framework of the celebrations for the IAU 100th anniversary  and the astronomical breakthroughs that have shaped science, technology and culture throughout the last century.
