Presentation
The next robot sent to Mars by the NASA has to use a gnomon, in order to determine the geographical north of the planet. How do these thousand years old objects, which principle is to stand in the light and cast shadows, remain relevant for future research? How have they gone through centuries, and how do scholars located throughout the globe have exploited the possibilities they offered ? These are the questions that we will try to explore in a hundred and few minutes.
